Referring to fig. 2, fig. 2 is a flowchart of a method for determining a collision resource according to an embodiment of the present invention, where the method is applied to a terminal, as shown in fig. 2, and includes the following steps:

step 201, determining whether there are conflict time resources in a plurality of service cells of the terminal according to activation information of a secondary cell (Scell), wherein the plurality of service cells include the secondary cell, and the conflict time resources refer to: different time resources are configured for the uplink and the downlink of different service cells;

wherein the activation information includes at least one of:

the state of the secondary cell and the command receiving time;

Wherein, the secondary cell may be one or more. The plurality of cells may belong to a plurality of cells of the network device, or may belong to a plurality of cells of the same network device.

The uplink and downlink configuration of the different service cells may be that, on the same time resource, both the service cells are configured as downlink time resources and the other service cells are configured as uplink time resources, or that, on the same time resource, both the service cells are configured as downlink reception and the other service cells are configured as uplink transmission. This results in a half duplex (half duplex) terminal being unable to transmit simultaneously with the multiple serving cells on the time resource, resulting in collisions.

The determining whether the conflict time resources exist in the multiple service cells of the terminal according to the activation information of the secondary cells may be determining the state of each secondary cell according to the activation information of the secondary cells, and then determining whether the conflict time resources exist in the multiple service cells of the terminal according to the state of each secondary cell, or determining whether the conflict time resources exist in the multiple service cells of the terminal according to the state of each secondary cell and the primary cell. For example: it can determine whether the downlink transmission configuration of a certain secondary cell conflicts with the uplink/downlink/flexible resource configuration of other cells, and whether the uplink/downlink transmission configuration of a certain secondary cell conflicts with the uplink/downlink/flexible resource configuration of other cells. If the time resource a of an activated secondary cell is a downlink time resource, and the time resource a is an uplink time resource according to the time resource a of another activated secondary cell, it is determined that the time resource a is a collision time resource.

In addition, the determining whether the conflict time resource exists in the plurality of service cells of the terminal may be determining whether the conflict time resource exists, and determining which time resource the conflict time resource is.

In the embodiment of the present invention, the time resource may include at least one of the following: symbols, slots, subframes, such as orthogonal frequency division multiplexing (Orthogonal frequency division multiplex, OFDM) symbols. Of course, this is not limited, and for example: the time resource may be a newly defined time resource in a subsequent protocol, such as a smaller time resource than the symbol.

It should be noted that the conflict time resource may be one or more time resources. The terminal may be a half duplex (half duplex) terminal.

Optionally, the terminal may meet at least one of the following conditions:

the network is configured with a plurality of service cells of the terminal and is configured with half duplex behavior enabled;

the terminal does not have the capability to transmit and receive simultaneously on multiple serving cells;

the terminal reports the capability of supporting the behavior of the half-duplex terminal;

the terminal is not configured for listening to the downlink control information format (DCI format) 2-0.

In the embodiment of the invention, whether the conflict time resources exist in the plurality of service cells of the terminal can be determined, so that the transmission of the terminal can be selectively transmitted in the conflict time resources, the conflict is avoided, the transmission performance of the terminal is improved, and whether the transmission on the plurality of service cells can be transmitted can be determined, so that the resources on each service cell can be more fully utilized. In addition, according to the activation information of the auxiliary cell, whether the conflict time resources exist in a plurality of service cells of the terminal is judged, so that the understanding of the sending and receiving between the network equipment and the terminal is consistent aiming at the conflict time resources, the utilization rate of uplink and downlink resources is improved, and the excessive discarding of uplink and downlink transmission is avoided.

As an optional implementation manner, the uplink and downlink configuration of the different serving cells include: at least one of a first time resource, a second time resource, a third time resource, and a fourth time resource;

wherein, on the first time resource, the configuration of the serving cell is uplink time resource and the configuration of the serving cell is downlink time resource;

on the second time resource, the configuration of the serving cell is uplink transmission, and the configuration of the serving cell is downlink reception;

on the third time resource, the configuration of the serving cell is uplink transmission, and the configuration of the serving cell is downlink time resource;

on the fourth time resource, the configuration of the serving cell is uplink time resource, and the configuration of the serving cell is downlink receiving.

The first time resource may be understood as an uplink time resource configured in some serving cells, and a downlink time resource configured in other serving cells; the second time resource may be understood as being configured for uplink transmission in some serving cells and configured for downlink reception in other serving cells; the third time resource may be understood as being configured as uplink transmission in some serving cells, and configured as downlink resource in other serving cells; the fourth time resource may be understood as being configured as an uplink resource in some serving cells and configured as a downlink reception in other serving cells.

In this embodiment, resources with uplink and downlink time resource conflicts may be determined, and resources with uplink and downlink transmission conflicts may also be determined. That is, the collision is that uplink and downlink symbols are configured in different service cells on the same time resource, or uplink and downlink transmissions are opposite, or uplink and downlink transmissions are not matched with uplink and downlink symbols.

As an optional implementation manner, the determining whether there are conflict time resources in the multiple service cells of the terminal according to the activation information of the secondary cell includes:

judging whether conflict time resources exist in a plurality of service cells of the terminal according to configuration information of an activated cell in the plurality of service cells;

wherein the active cell comprises:

an activated secondary cell; or alternatively

A primary cell and an active secondary cell.

Wherein the activated secondary cell is determined according to activation information of the secondary cell.

In this embodiment, whether the conflict time resource exists in the multiple service cells of the terminal is determined only according to the configuration information of the activated cell, and whether the time resource conflict exists in the uplink and downlink between the multiple service cells is determined without using the configuration information of the deactivated secondary cell. The method can avoid consistent understanding of the conflict time resources by the network equipment and the terminal, thereby improving the resource utilization rate and the transmission performance.

Optionally, the configuration information includes at least one of:

uplink transmission configuration information of an activated uplink Bandwidth Part (BWP);

downlink receiving configuration information of the activated downlink BWP;

uplink sending configuration information of a service cell;

downlink receiving configuration information of a serving cell;

configuration information of uplink resources;

configuration information of downlink resources;

configuration information of flexible resources.

It should be noted that the content of the configuration information of different active cells may be the same or different, where the content refers to at least one of the foregoing multiple items. For example: some of the active cell's configuration information includes flexible resource's configuration information, while other active cell's configuration information does not include flexible resource's configuration information. In addition, the uplink transmission configuration information and the downlink reception configuration information of the serving cell may be understood as uplink transmission configuration information and downlink reception configuration information of the active cell, because the active cell is the serving cell. The configuration information may be RRC configuration information, but may be other configuration information, and is not limited thereto.

In addition, the active uplink BWP may be a dormant uplink BWP (dormant BWP) or a non-dormant uplink BWP, and the active downlink BWP may be a dormant downlink BWP (dormant BWP) or a non-dormant downlink BWP.

Further, the configuration information for the dormant downlink BWP may be at least one of the following configuration information:

CSI-RS and synchronization signal blocks (Synchronization Signal Block, SSB).

Wherein, the CSI-RS may include at least one of:

CSI-RS for BFD, CSI-RS for CSI measurement.

The uplink resource, the downlink resource and the flexible resource may be an uplink symbol, a downlink symbol and a flexible symbol, or may be an uplink time slot, a downlink time slot and a flexible time slot, or may be an uplink subframe, a downlink subframe and a flexible subframe.

In addition, the uplink transmission configuration information may include configuration information of at least one of:

physical random access channel (Physical Random Access Channel, PRACH), sounding reference signal (Sounding Reference Signal, SRS), physical uplink shared channel (Physical uplink shared channel, PUSCH) and physical uplink control channel (Physical Uplink Control Channel, PUCCH);

the downlink reception configuration information may include configuration information of at least one of:

a physical downlink shared channel (Physical downlink shared channel, PDSCH), a channel state information reference signal (Channel state indication reference signal, CSI-RS), and a physical downlink control channel (Physical downlink control channel, PDCCH).

Optionally, in the case that the terminal receives the activation command, the activated secondary cell may include a secondary cell activated by the activation command; or alternatively

In the case that the terminal receives the deactivation command, the activated secondary cell may not include the secondary cell deactivated by the deactivation command.

For example: if a secondary cell is an active serving cell, downlink reception of an active downlink BWP configuration of the active Scell, uplink transmission of an active uplink BWP configuration, downlink reception of the Scell configuration, uplink transmission of the Scell configuration may be used, and RRC configuration of at least one of uplink time resources, downlink time resources, and flexible time resources of the Scell configuration may determine whether there is a collision with other serving cells.

Also for example: if a certain auxiliary cell is a deactivated service cell, whether the resources of the service cell conflict or not is not judged.

Or a certain secondary cell is a deactivated serving cell, the UE considers all symbols on the deactivated serving cell as flexible symbols. For example: for a deactivated secondary cell of the plurality of serving cells, all time resources of the deactivated secondary cell are flexible time resources. Where the time resource may be a symbol, a slot, or a subframe.

Since whether a plurality of service cells collide or not is judged on each time resource, only uplink transmission configured by high-level signaling, or downlink received cells, or time resources configured by high-level signaling as downlink or uplink are considered, that is, flexible time resources configured by high-level signaling are not considered, and if a symbol of a certain service cell is configured as a flexible symbol by high-level signaling, the determination of a reference service cell not included by the cell is performed. The determining of the reference serving cell includes determining a cell with a lowest cell index value among a plurality of serving cells, that is, determining a cell with a lowest cell index value, wherein the cell is configured as a flexible symbol without considering symbols by higher layer signaling. The UE performs the determination of the reference service cell in the cell of which the uplink transmission or the downlink reception is configured in the higher layer signaling of the time resource or the higher layer signaling is configured as the downlink or the uplink time resource. Further, if the symbol of a certain serving cell is configured as a flexible symbol by higher layer signaling, the serving cell does not make a determination as to whether there is a conflicting time resource with a reference serving cell or other serving cells on the symbol.

Thus if for a deactivated secondary cell the UE assumes time resources on the serving cell as flexible time resources, the secondary cell is not included in the determination of the reference serving cell according to the rules described above. Further, the secondary cell does not make a determination as to whether there is a conflicting time resource with the reference serving cell or other serving cells.

Optionally, in the case that the terminal receives the activation command:

the activated secondary cell at the first time comprises a secondary cell activated by the activation command; and/or

The activated secondary cell does not comprise the secondary cell activated by the activation command at the second time;

the difference between the first time and the receiving time of the activation command is greater than or equal to T1 time, the difference between the second time and the receiving time of the activation command is less than or equal to T1 time, and the T1 time is the time delay of activating the secondary cell.

In this embodiment, the active cell for determining the conflict time resource may be accurately determined according to the T1 time, so that it may be more effectively ensured that the network device and the terminal understand the conflict time resource consistently. For example: the terminal receives MAC-CE to instruct the secondary cell to activate, the terminal uses the downlink receiving of the activated downlink BWP configuration of the activated Scell, the uplink sending of the activated uplink BWP configuration, the downlink receiving of the Scell configuration, the uplink sending of the Scell configuration, the RRC configuration of at least one of the uplink time resource, the downlink time resource and the flexible time resource of the Scell configuration to determine whether conflict exists with other service cells, wherein when judging a plurality of service cell conflict time resources before the T1 time, the secondary cell is considered to be a deactivated cell.

Optionally, the time resource of the secondary cell activated by the activation command at the second time is a flexible time resource.

For example: the terminal considers the time resource of the deactivated secondary cell as flexible time resource, and the terminal considers the time resource of the secondary cell as flexible time resource before the time of T1.

Thus if for a deactivated secondary cell the UE assumes time resources on the serving cell as flexible time resources, the secondary cell is not incorporated into the reference serving cell determination until time T1, as per the rules described above. Further, the secondary cell does not make a determination as to whether there is a conflicting time resource with the reference serving cell or other serving cells.

Optionally, in the case that the terminal receives the deactivation command:

the activated secondary cell at a third time comprises a secondary cell deactivated by the deactivation command; and/or

At a fourth time the activated secondary cell does not include the secondary cell deactivated by the deactivation command;

the difference between the third time and the receiving time of the deactivation command is less than or equal to a T2 time, the difference between the fourth time and the receiving time of the activation command is greater than or equal to the T2 time, and the T2 time is a time delay of deactivating the secondary cell.

In this embodiment, the deactivation cell that is not used for judging the conflict time resource may be accurately determined according to the T2 time, so that it may be more effectively ensured that the network device and the terminal understand the conflict time resource consistently. For example: the terminal receives the MAC-CE indication to deactivate the secondary cell, and stops using the downlink receiving of the activated downlink BWP configuration of the activated secondary cell, the uplink sending of the activated uplink BWP configuration, the downlink receiving of the Scell configuration, and the uplink sending of the Scell configuration, and the RRC configuration of at least one of the uplink time resource, the downlink time resource and the flexible time resource of the Scell configuration determines whether conflicts exist with other service cells, wherein the secondary cell is considered to be the activated cell when judging a plurality of service cell conflict time resources before the T2 time.

Optionally, at the fourth time, the time resource of the secondary cell deactivated by the deactivation command is a flexible time resource.

For example: and the terminal considers the time resource of the deactivated auxiliary cell as flexible time resource, and the terminal considers the time resource of the auxiliary cell as flexible time resource after the T2 time.

Thus if for a deactivated secondary cell the UE assumes time resources on the serving cell as flexible time resources, the configuration on the secondary cell after the T2 time is not incorporated into the reference serving cell determination, as per the rules above. Further, the secondary cell does not make a determination as to whether there is a conflicting time resource with the reference serving cell or other cells.

As an alternative embodiment, the configuration information of the deactivated secondary cells in the plurality of serving cells is not used to determine whether there are conflicting time resources in the plurality of serving cells.

As an alternative embodiment, the method further comprises:

and determining a reference serving cell (reference cell) in the plurality of serving cells according to the activation information of the secondary cell.

In this embodiment, since the reference serving cell of the plurality of serving cells is determined according to the activation information of the secondary cell, it is ensured that the network device is consistent with the terminal's understanding of the reference serving cell.

Optionally, the reference serving cell is: the cell with the lowest cell index value in the activated cells in the plurality of service cells;

wherein the active cell comprises:

an activated secondary cell; or alternatively

A primary cell and an active secondary cell.

It should be noted that, the activated secondary cell may refer to the above determination of the activated cell for determining the conflict time resource, which is not described herein.

Optionally, the plurality of serving cells are within one frequency band, or within one frequency band combination.

In this embodiment, determination of the conflict time resources and determination of the reference serving cell among the plurality of serving cells in the same frequency band can be achieved, and determination of the conflict time resources and determination of the reference serving cell among the plurality of serving cells in the same frequency band combination can be achieved.

As an alternative embodiment, the following actions may be performed for the above mentioned conflict time resource terminal:

if at least one of the time resources is a higher layer signaling indicating downlink time resource on the reference serving cell or a higher layer signaling indicating receiving PDCCH, PDSCH) or CSI-RS on the reference serving cell, not transmitting PUCCH, PUSCH or PRACH on the time resources on the other serving cells;

If the time resource in the time resource of the other service cell is the downlink time resource indicated by the higher layer signaling in the reference service cell or the higher layer signaling is indicated to be used for receiving the PDCCH, the PDSCH or the CSI-RS in the reference service cell, the SRS is not transmitted in the time resource of the other service cell.

If at least one of the time resources of other service cells is an uplink time resource indicated by a higher layer signaling on the reference service cell or is indicated by the higher layer signaling to be used for transmitting uplink SRS, PUCCH, PUSCH or PRACH on the reference service cell, receiving PDCCH, PDSCH or CSI-RS indicated by the higher layer signaling on the time resources of other service cells;

the high-layer signaling indicates downlink on other service cells and the time resource for transmitting SRS, PUCCH, PUSCH or PRACH on the reference service cell is flexible time resource;

and indicating the high-layer signaling to be uplink on other service cells and indicating the time resource for receiving the PDCCH, the PDSCH or the CSI on the reference service cell by the high-layer signaling as flexible time resource.

As an alternative embodiment, all time resources of a Dormant secondary cell (dorman Scell) of the multiple serving cells are flexible time resources, wherein the Dormant secondary cell is in active state and the active BWP is a secondary cell that is Dormant BWP (Dormant BWP).

Where the time resource may be a symbol, a slot, or a subframe.

Since whether a plurality of service cells collide or not is judged on each time resource, only uplink transmission configured by high-level signaling, or downlink received cells, or time resources configured by high-level signaling as downlink or uplink are considered, that is, flexible time resources configured by high-level signaling are not considered, and if a symbol of a certain service cell is configured as a flexible symbol by high-level signaling, the determination of a reference service cell not included by the cell is performed. The determining of the reference serving cell includes determining a cell with a lowest cell index value among a plurality of serving cells, that is, determining a cell with a lowest cell index value, wherein the cell is configured as a flexible symbol without considering symbols by higher layer signaling. The UE performs the determination of the reference service cell in the cell of which the uplink transmission or the downlink reception is configured in the higher layer signaling of the time resource or the higher layer signaling is configured as the downlink or the uplink time resource. Further, if the symbol of a certain serving cell is configured as a flexible symbol by the higher layer signaling, and no higher layer signaling is configured for uplink transmission or downlink reception on the symbol, the serving cell does not make a determination on whether there is a conflict time resource between the symbol and the reference serving cell or other serving cells.

Thus if for (dorman Scell) the UE assumes time resources on the serving cell as flexible time resources.

Optionally, the all time resources include:

the network side configures downlink time resources and uplink time resources.

The downlink time resource and the uplink time resource configured by the network side may be a downlink time resource and an uplink time resource configured by a higher layer signaling, for example: even if higher layer signaling configures the symbols of the dormant serving cell as downlink time resources or uplink time resources, the UE ignores these configurations, assuming these time resources are flexible time resources.

The secondary cell is not included in the determination of the reference serving cell, as per the rules above. Further, the secondary cell does not make a determination as to whether there is a conflicting time resource with the reference serving cell or other serving cells.

As an alternative embodiment, configuration information of a Dormant secondary cell (dorman Scell) of the plurality of serving cells is not used when determining a reference serving cell of the plurality of serving cells;

or determining a reference serving cell in the plurality of serving cells according to configuration information of an activated cell in the plurality of serving cells, wherein the activated cell comprises: an activated secondary cell, or a primary cell and an activated secondary cell, wherein the activated secondary cell is a non-dormant secondary cell;

Wherein the Dormant secondary cell (dorman Scell) is in active state and active BWP is the Dormant BWP (Dormant BWP) secondary cell.

The configuration information of the active cell may be all or part of configuration information of the active cell.

In this embodiment, the determination may be performed without depending on the configuration information of the dormant secondary cell in determining the reference serving cell.

As an alternative embodiment, the configuration information of the Dormant secondary cell (dorman Scell) in the multiple serving cells is not used to determine whether there are conflicting time resources in the multiple serving cells of the terminal; or judging whether conflict time resources exist in a plurality of service cells of the terminal according to configuration information of an activated cell in the plurality of service cells, wherein the activated cell comprises: an activated secondary cell, or a primary cell and an activated secondary cell, wherein the activated secondary cell is a non-dormant secondary cell;

In this embodiment, it may be determined whether the conflict time resource exists in the multiple service cells of the terminal, and the determination is not performed according to the configuration information of the dormant secondary cell.

Optionally, the configuration information of the dormant secondary cell includes at least one of the following:

configuration information of uplink resources;

transmission configuration of semi-persistent scheduling (SPS) PDSCH;

transmission configuration of SRS;

transmission configuration of PUCCH.

Optionally, the CSI-RS is not used for at least one of:

radio Resource Management (RRM) measurements, beam Failure Detection (BFD), and Channel State Information (CSI) measurements.

In this embodiment, the CSI-RS may be implemented to be CSI-RS used for applications other than the RRM measurement, BFD, and CSI measurement, so that the transmission configuration of the CSI-RS that may be used for the RRM measurement, BFD, and CSI measurement may be used to determine a serving reference cell, and to determine whether there are conflicting time resources in multiple serving cells of the terminal.

It should be noted that, as an implementation manner of the network device side corresponding to the embodiment shown in fig. 2, a specific implementation manner of the embodiment may refer to a related description of the embodiment shown in fig. 2, so that in order to avoid repetitive description, the embodiment is not repeated. In this embodiment, it may also be determined whether there are conflicting time resources in multiple serving cells of the terminal.

The conflict resource judging method provided by the embodiment of the invention is illustrated by a plurality of embodiments:

example 1:

if the network configures a plurality of Serving cells, and if a deactivated Serving cell exists, the terminal only uses uplink and downlink transmission configuration of the activated Scell, or uplink and downlink resource configuration, to determine whether uplink and downlink between the plurality of Serving cells collide (i.e. the above-mentioned collision time resource). And determining whether uplink and downlink conflict (namely the conflict time resource) among a plurality of serving cells is caused or not by not using uplink and downlink transmission configuration of the deactivated Scell or uplink and downlink resource configuration.

Example 2:

in this embodiment, in one frequency band (frequency band), all serving cells are scells, specifically as follows:

if all cells are active scells, then the cell with the lowest multiple serving cell secondary cell index (serving cell Scell index) is the reference cell.

If an inactive Scell is included, the cell with the lowest index in the active Scell is the reference cell.

For example, in one frequency band, if 3 scells are included, the index values are n1, n2, n3, where n1< n2< n3, respectively, and if three scells are active scells, the cell with index value n1 is a reference cell; if Scell n1 is a deactivated cell, n2 is reference Scell.

Example 3:

after receiving the activation or deactivation command of the Scell, the terminal determines the conflict time resource according to the activation delay of the Scell, which is specifically as follows:

if the terminal receives the indication of the Scell activation by the MAC-CE, the terminal uses the downlink receiving of the activated downlink BWP configuration of the activated Scell, the uplink sending of the activated uplink BWP configuration, the downlink receiving of the Scell configuration, the uplink sending of the Scell configuration, and the RRC configuration of at least one of the uplink time resource, the downlink time resource and the flexible time resource of the Scell configuration determines whether conflicts exist with other serving cells or not; before the time of T1, the Scell is considered as a deactivated cell, and uplink and downlink transmission configuration or uplink and downlink resource configuration on the Scell is not used to determine whether a plurality of serving cells collide with each other.

Wherein after the secondary cell activation command (SCell activation command) is received at slot n, the secondary cell activation command is sent to the cellThe T1 can be equal to the HARQ feedback time T _HARQ Scell activation delay T _activation Time for CSI reporting T _{CSI_Reporting} In connection with, for example, a terminal being no later than a slotThere is a need to be able to report valid CSI and perform Scell activation actions. That is, T1 is +.>The NR slot length is the number of slots contained in 1 ms.

Wherein T is _HARQ T in ms for the time between the downlink data transmission (DL data transmission) and the HARQ feedback _{CSI_Reporting} The method comprises the steps of receiving the time delay of the uncertainty of the first CSI-RS resource, processing the time delay of the CSI reporting, and obtaining the time delay corresponding to the uncertainty of the first CSI reporting resource. The T is _activation Time delay for activating Scell, T according to different scenes and configurations _activation The times are different, for example: may be related to at least one of the following factors:

whether Scell is a known Scell;

configuration of radio resource management measurement time configuration (SS block based RRM Measurement Timing Configuration, SMTC) period;

whether the UE configures periodic or persistent CSI reporting;

the frequency band of the Scell;

whether the band has an already activated cell.

For example: if the activated Scell is a known Scell and belongs to the frequency range FR1, T is the case if the number of secondary cell emulated periods (measurement cycle) is less than or equal to 160ms _activation May be equal to T _FirstSSB +5ms；

In case the secondary cell measurement cycle is greater than 160ms, T _activation May be equal to T _{SMTC_MAX} +T _rs +5ms。

In addition, if the activated Scell is unknownAnd belongs to the frequency range FR1, then T in case of one Scell detection _activation May be equal to 2×T _{SMTC_MAX} +2×T _rs +5ms。

In addition, if the activated secondary cell belongs to the frequency range FR2 and there is at least one activated serving cell on the frequency band of FR2 and the following condition is satisfied, T _activation May be equal to T _FirstSSB +5ms：

Wherein, in the case of one detection of Scell, T _activation May be equal to 2×T _{SMTC_MAX} +2×T _rs +5ms。

If the activated Scell belongs to FR2 and there is at least one activated serving cell on the band of FR2, and the following condition is satisfied, the Tactization_time is tfirstssb+5ms:

SMTC configured with the Scell

The SSB on the activated other Scell and the SSB of the Scell can guarantee spatial quasi co-location.

Wherein T is as described above _{SMTC_MAX} The method comprises the following steps: maximum value of SMTC period corresponding to the plurality of secondary cells;

t as described above _FirstSSB The method comprises the following steps: at n+T _HARQ After +3ms, time from the next SSB;

t as described above _rs The method comprises the following steps: if the SMTC configuration of the secondary cell is received in the signaling of the added secondary cell, T _rs Is the SMTC period. Otherwise, the SSB is the same in frequency and the subcarrier spacing is the same, and the SMTC period is configured through the high-layer signaling measObjectNR.

Example 4:

if the terminal receives the MAC-CE indication to deactivate the Scell, the terminal stops using the downlink receiving of the activated downlink BWP configuration of the activated Scell, the uplink sending of the activated uplink BWP configuration, the downlink receiving of the Scell configuration, the uplink sending of the Scell configuration, and the RRC configuration of at least one of the uplink time resource, the downlink time resource and the flexible time resource of the Scell configuration determines whether collision exists with other serving cells or not after the T2 time; when judging a plurality of service cell conflict time resources before the time of T2, considering the Scell as an activated cell, wherein:

the T2 may be n+t_harq+x ms, where X is a number greater than or equal to 0.

THARQ is the time between downlink DL data transmission and HARQ feedback.

Example 5:

the activated BWP of the activated Scell may be dormant BWP, i.e. dorman BWP, except that the Scell may be in activated and deactivated states. In case the active BWP is a dorman BWP, the terminal may only need to perform at least one of the following operations on the BWP: beam failure detection (beam failure detection), CSI measurement, other RRC configurations are not valid. Such as RACH configuration, SRS configuration, PUCCH configuration, configuration grant (PUSCH configuration, PDCCH search space set (search space set) configuration, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) PDSCH configuration, etc.

When determining whether uplink and downlink configurations of a plurality of serving cells collide, for a scell that activates BWP to be dorman BWP, the UE may still use configuration information (e.g., RRC configuration) of the downlink BWP, and may determine whether there is a collision with other serving cells on the corresponding resource only by using the following downlink configuration:

CSI-RS and/or SSB.

Wherein, the CSI-RS may include at least one of:

CSI-RS for BFD, CSI-RS for CSI measurement.

Or, the terminal uses uplink and downlink transmissions of other downlink BWP or configuration of uplink BWP except for dorman BWP to determine whether there is an uplink and downlink configuration conflict with other serving cells. The BWP may be at least one of:

a first non-dormant BWP (first non dormant BWP);

the first to activate downlink BWP (first Active Downlink BWP);

the network side indicates the BWP through RRC signaling.

The BWP may be a downlink BWP, and the corresponding uplink BWP is an uplink BWP with the same ID as the downlink BWP.

Wherein, the first-non-dorman-BWP is configured by the network, and when the terminal receives the DCI indicating that the activated BWP of the Scell is the BWP of the dorman, the UE uses the BWP as the activated DL BWP.

The first actionlowlinkbwp described above is network configured, and when the Scell is activated, the UE uses the BWP as an activated BWP. The terminal uses the downlink configuration in first-non-dorman-BWP or first ActiveDown-LinkBWP as the downlink configuration of the scell that activates downlink BWP as dorman BWP, the configuration of the uplink BWP with the same BWP ID as the uplink configuration of the scell that activates uplink BWP as dorman BWP, and judges whether the configuration of the serving cell collides with the uplink and the downlink of other serving cells according to the downlink or the uplink configuration.

Or, the network may instruct, by using the RRC, one BWP-ID, and the UE uses the configuration of the uplink BWP or the downlink BWP corresponding to the ID, as a configuration judgment of the serving cell and uplink/downlink collision of other serving cells.

Example 6:

the network may configure the terminal with a plurality of serving cells, wherein the activation BWP of at least one scell is dorman BWP, and the terminal has no configuration information of PDSCH on the dorman BWP or obtains PDSCH configuration information, but does not use the configuration information, where the configuration information includes information such as PDSCH time domain resource allocation.

In the case where the network uses the HARQ-Ack codebook (i.e., the semi-static codebook) of Type 1 (Type-1) for the HARQ-Ack feedback configured for the terminal, the terminal may determine PDSCH occalation and determine the HARQ-Ack codebook according to the configuration of the time domain resource allocation of the PDSCH in the active downlink BWP of the active BWP on each serving cell.

Further, in the case where the active downlink BWP of one or more serving cells of the UE is dorman BWP, there is no PDSCH occasin on the serving cells, i.e. there is no PDSCH in the HARQ-Ack codebook, due to the configuration of PDSCH or not being used. Therefore, the bit length in the HARQ-Ack codebook fed back by the terminal can be reduced, the transmission performance of HARQ-Ack feedback can be improved, or the resources occupied by HARQ-Ack feedback bits can be reduced.

Or, in case that the active downlink BWP of one or more serving cells of the terminal is dorman BWP, the UE determines occalation of the PDSCH using PDSCH configuration of other downlink BWP except dorman BWP and determines HARQ-Ack codebook based on the occalation. PDSCH configuration of the downlink BWP of the serving cell may be used as follows:

first-non-dormant-BWP

firstActiveDownlinkBWP

BWP indicated by the network through RRC signaling

Wherein, the first-non-dorman-BWP is configured by the network, and when the UE receives the DCI indicating that the activated BWP of the Scell is the BWP of the dorman, the UE uses the BWP as the activated DL BWP.

The first actionlowlinkbwp is network-configured, and the UE uses the BWP as an activated BWP after the Scell is activated. The UE uses the PDSCH configuration in first-non-dorman-BWP or first actiondownlink BWP as the PDSCH configuration of the scell that activates downlink BWP to dorman BWP and is used to determine the HARQ-Ack codebook.

Alternatively, the network may instruct one BWP through RRC, and the UE uses PDSCH configuration in the BWP as PDSCH configuration of the scell that activates downlink BWP as dorman BWP and uses for determining HARQ-Ack codebook.

The determining of the HARQ-Ack codebook is determining the length of the HARQ-Ack codebook, the bit sequence in the codebook and other information.

Example 7:

The activated BWP of the activated Scell may be dormant BWP, i.e. dorman BWP, except that the Scell may be in activated and deactivated states. In case the active BWP is a dorman BWP, the terminal may only need to perform at least one of the following operations on the BWP: beam failure detection (beam failure detection), CSI measurement, preferably partial SRS transmission, other RRC configurations are not valid. Such as RACH configuration, SRS configuration, PUCCH configuration, configuration grant (PUSCH configuration, PDCCH search space set (search space set) configuration, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) PDSCH configuration, etc. Preferably, for SRS transmission, only partial SRS transmission may be supported, for example, SRS with a period greater than a preset value or a configuration value may be transmitted.

In determining whether uplink and downlink configurations of a plurality of serving cells collide, the UE ignores an uplink symbol or a downlink symbol of the RRC configuration for scells that activate BWP to dorman BWP, and the UE assumes all symbols for scells that activate BWP to dorman BWP to be flexible symbols.

If the symbol of the Scell has no valid RRC configured transmission or reception, the serving cell is not used as a serving cell for reference cell determination, because the symbol of the Scell is assumed to be a flexible symbol. And determining a reference service cell in other cells judged to be downlink symbols or uplink symbols.

If the symbol of the Scell contains the uplink transmission or the downlink reception of the effective RRC configuration, if the effective RRC configuration contains downlink transmission, the symbol is determined to be a downlink symbol; if the validated RRC configuration contains uplink transmission, the symbol is determined to be an uplink symbol. The uplink transmission of the RRC configuration includes configuration information of at least one of: physical random access channel PRACH, sounding reference signal SRS, physical uplink shared channel PUSCH, physical uplink control channel PUCCH; the downlink reception of the RRC configuration includes configuration information of at least one of: a physical downlink shared channel PDSCH, a channel state information reference signal CSI-RS and a physical downlink control channel PDCCH.

On each symbol, according to whether the symbol in the plurality of service cells is an uplink symbol or a downlink symbol, firstly, determining a reference cell in the plurality of service cells, wherein the reference cell is the service cell with the lowest service cell index (number). The plurality of service cells include a primary cell, a primary secondary cell, or an activated secondary cell.

After determining a reference cell of the plurality of cells, it is determined on which cell to transmit or receive based on the configuration or scheduling of the reference cell and other cells. Comprises the following steps:

The embodiment of the invention can be realized specifically as follows:

determining whether conflict exists between configured Serving cells according to the actually activated Scell, and determining corresponding terminal behaviors;

the reference cells in each frequency band or each frequency band combination are determined according to the actually activated scells.

After receiving the activation or deactivation command of a certain Scell, the UE assumes that the Scell is a deactivated cell or an activated cell, and determines whether there is an uplink/downlink collision between Serving cells, before the maximum time delay of activation or deactivation.

Therefore, the terminal can determine whether a plurality of serving cells collide or not according to the activated Scell, so that the utilization ratio of uplink and downlink resources is improved, and excessive discarding of uplink and downlink transmission is avoided. And in the process of activating or deactivating the Scell, using the maximum time delay as the effective time of the uplink and downlink configuration of the Scell, and avoiding the ambiguity of the uplink and downlink configuration between the network equipment and the terminal.
