Description

Communication method and communication device

Technical Field

The present application relates to the field of communications, and more particularly, to a method of communication and a communication device.

Background

In the ongoing standardization of 5G by the third generation partnership project (3rd Generation Partnership Project,3GPP), the maximum supported carrier bandwidth to 400MHz is considered. However, for the terminal side, not all terminal devices can support operations of communication, measurement, etc. of 400MHz bandwidth due to the costs of various different types of terminal devices. Meanwhile, in order to achieve the flexibility of system implementation and scheduling, in the discussion process of 5G, the network side agrees to send a plurality of synchronous signal blocks (Synchronization Signal block, SS blocks, SSB) on a wide bandwidth so that terminal equipment can measure or initially access on different SSBs.

Some SSBs of the plurality of SSBs on a bandwidth are not associated with the remaining system messages (REMAINING SYSTEM Information, RMSI). At the initial access time, the terminal device does not know which SSB to associate RMSI with before entering the network, since there is no advance information. Therefore, the terminal device needs to do synchronization search and detection of system messages for the frequency point of the synchronization frequency where each SSB is located. And when the terminal equipment detects that the current SSB is not associated RMSI, detecting the next candidate synchronous frequency point in sequence. This increases the detection complexity of the terminal device and the delay of network entry (RMSI successfully detected).

Therefore, in a system with multiple SSBs flexibly configured on a bandwidth, how to effectively reduce the detection complexity of the terminal device is a technical problem to be solved.

The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

Fig. 3 is a schematic diagram of a network architecture to which an embodiment of the present invention may be applied, and the network architecture may be a network architecture diagram of a New Radio Access (NR) in a next-generation wireless communication system. In the network architecture diagram, the network device may be divided into one centralized unit (centralized unit, CU) and a plurality of transmission reception points (transmission reception point, TRP)/Distributed Units (DUs), i.e. bandwidth-based units (bandwidth based unit, BBU) of the network device are reconfigured into DUs and CU functional entities. It should be noted that the form and number of the centralized units and TRP/DUs do not constitute limitations of the embodiments of the present invention. The configuration of the centralized units corresponding to each of the network devices 1 and 2 shown in fig. 2 is different, but the functions of each are not affected. It will be understood that the TRP/DU in the range of the centralized unit 1 and the dotted line is a constituent element of the network device 1, the TRP/DU in the range of the centralized unit 2 and the solid line is a constituent element of the network device 2, and the network device 1 and the network device 2 are network devices (or referred to as base stations) involved in the NR system.

The CU may handle wireless higher layer protocol stack functions, such as radio resource control (radio resource control, RRC) layer, packet data convergence layer protocol (PACKET DATA Convergence Protocol, PDCP) layer, etc., and even support a part of core network functions sinking to the access network, termed edge computing network, capable of meeting the higher demands of future communication networks on network latency for emerging services such as video, network purchase, virtual/augmented reality.

The S1-C interface illustrated in fig. 3 may be a standard interface between a network device and a core network, and the specific S1-C connected device is not shown in fig. 3.

Fig. 4 is a schematic diagram showing the structure of a synchronization signal block according to an embodiment of the present invention. It should be understood that fig. 4 is only an example and is not limiting on the embodiments of the present invention.

As shown in fig. 4, the synchronization signals, including the primary synchronization signal (primary synchronization signal, PSS) and the secondary synchronization signal (secondary synchronization signal, SSS), together with the physical broadcast channel (Physical Broadcast Channel, PBCH) may constitute one SSB, i.e., the NR primary synchronization signal (NR-PSS), the NR secondary synchronization signal (NR-SSS) and the NR physical broadcast channel (NR-PBCH) are transmitted in one SSB. For brevity, NR-PSS, NR-SSS, and NR-PBCH in a synchronization signal block may be abbreviated as PSS, SSS, and PBCH, respectively.

In addition, a plurality of SSBs may constitute one synchronization signal burst (SS burst set), and the SS burst set is periodically transmitted. That is, the network device transmits SSBs by using a periodic SS burst set transmission method, where each SS burst set includes a plurality of SSBs.

It should be understood that the names of the synchronization signal blocks and the synchronization signal pulse sets are not limited in this embodiment of the present invention, that is, they may be expressed as other names. For example, SSB may also be expressed as SS/PBCH block.

Fig. 5 shows a schematic diagram with multiple SSBs configured on one bandwidth. It should be understood that fig. 5 is only an example and is not limiting on embodiments of the present invention.

As shown in fig. 5, SSB3 is associated with RMSI, and SSB1 and SSB2 are not associated RMSI among 3 SSBs on one bandwidth. Under the condition of no information, the terminal equipment needs to search for the synchronization and detect RMSI for the frequency point of the synchronization frequency where each SSB1, SSB2 and SSB3 is located. And when the terminal equipment detects that the current SSB is not associated RMSI, detecting the next candidate synchronous frequency point in sequence. This greatly increases the detection complexity of the terminal device and the delay of network access.

In view of this, the embodiment of the invention provides a technical scheme, which can reduce blind detection of terminal equipment, reduce detection complexity of the terminal equipment, and reduce power consumption and time delay of the terminal equipment.

It should be appreciated that RMSI described above may also be transformed into other control information. In addition, the technical scheme of the embodiment of the invention can be applied to a cellular and relay scene and a D2D scene. In the embodiment of the present invention, control information is described as an example. For cellular and relay scenarios, the control information may be a system message (system information, SI), such as RMSI, or other system message (other system information, OSI). For the D2D scene, the control information is control information for a transmitting end to schedule a receiving end to receive data. However, the embodiment of the present invention is not limited thereto.

It should also be understood that for cellular and relay scenarios, the physical broadcast channel in the embodiments of the present invention may be a PBCH, and the synchronization signal identification may be a physical cell identification. For D2D scenarios, the physical broadcast channel in the embodiment of the present invention may be a physical sidelink broadcast channel (PHYSICAL SIDELINK Broadcast Channel, PSBCH), and the synchronization signal identifier may be a synchronization signal area identifier of the D2D link. However, the embodiment of the present invention is not limited thereto.

It should also be appreciated that the association of SSBs with control information may include, but is not limited to, the following:

mode one: the association indicates that there is control information being sent on the same time domain resource as the SSB or on time domain resources subsequent to the SSB in a protocol-specified or predefined manner. This subsequent time domain resource has a certain temporal correspondence with SSB. For example: adjacent to SSB, or spaced apart for a period of time.

Mode two: the association is resource configuration information indicating control information associated with the terminal device through a physical broadcast channel in the SSB. Such as the location of the resource pool of the control information, or the configuration of the indication information of the control information, etc.

Fig. 6 shows a schematic flow chart of a method of communication of one embodiment of the invention. The first device in fig. 6 is a transmitting device, and may be, for example, a network device or a terminal device described above; the second device is a receiving device, which may be, for example, the terminal device described above.

The first device determines first indication information 610, wherein the first indication information indicates a resource location of a second synchronization signal block associated with control information.

In the embodiment of the present invention, when the first device sends the synchronization signal block (denoted as a first synchronization signal block), the first device determines the resource position of the synchronization signal block (denoted as a second synchronization signal block) associated with the control information, and further indicates the resource position of the second synchronization signal block to the second device in the first synchronization signal block.

It should be appreciated that the resource location may include: time domain location, or frequency domain location, or time frequency location. For example, when the first indication information indicates a time domain position, it indicates that the second synchronization signal block and the first synchronization signal block may not be on the same time slot. The frequency domain position is described below as an example, but the embodiment of the present invention is not limited thereto.

Alternatively, the resource location of the second synchronization signal block may be an absolute location of the second synchronization signal block in the bandwidth or a relative location with respect to the first synchronization signal block.

For example, the first indication information may indicate a frequency offset value of the second synchronization signal block from the first synchronization signal block, or the first indication information may indicate a frequency position of the physical resource block (Physical Resource Block, PRB) of the second synchronization signal block in the current carrier.

It is to be understood that the second synchronization signal block may be identical to the first synchronization signal block, i.e. this is the case when the first synchronization signal block is associated with the control information. Accordingly, in this case, the relative deviation value of the time domain resource or the frequency domain resource indicated by the first indication information is 0, or the indicated absolute position in the bandwidth is the position of the first synchronization signal block.

Alternatively, the first device may determine the first indication information when the first synchronization signal block is not associated with the control information.

That is, the control information is associated with the first synchronization signal block, and the first indication information may not be required. The first device configures the first indication information when the first synchronization signal block is not associated with the control information.

The first device sends 620 a first synchronization signal block, wherein a physical broadcast channel in the first synchronization signal block carries the first indication information.

The first device sends the first indication information carried in a physical broadcast channel in the first synchronization signal block to the second device.

Alternatively, in one embodiment of the present invention, the first indication information may be carried in a reserved field of the physical broadcast channel.

Alternatively, in one embodiment of the present invention, the physical broadcast channel may be reset. For example, the physical broadcast channel may include a three-part field, wherein,

Optionally, the first field and the second field partially or completely overlap in bits occupied by the physical broadcast channel.

For example, as shown in fig. 7, field 1 and field 2 are valid when SSB associates or does not associate control information, and are the third fields described above; fields 3-6 are the first fields described above when SSB associates control information; the fields 3 'and 4' are valid when SSB does not associate control information, and for the second field, the first indication information may be carried in the fields 3 'and 4'.

That is, when the current SSB does not associate with the control information, other fields in the physical broadcast channel field except for a part of fields that must be used in measurement may be disabled, and after the other fields are disabled, the remaining bits may be reconfigured to be a new field for carrying the first indication information.

Taking PBCH as an example, when the SSB does not associate with control information, in the PBCH, except for the super frame number (HYPER FRAME number, HFN), the SSB time sequence number (SSB time index), other original fields, such as "RMSI control resource", "subcarrier offset value of synchronization signal in PRB", "system frame number (SYSTEM FRAME number, SFN)" and the like, will fail, and the PBCH bit left by the field after failure can be used to carry the first indication information.

For an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) system that performs 8192-point fast fourier transform (Fast Fourier Transformation, FFT), it is assumed that one PRB occupies 12 subcarriers, and there are 8192/12=682 PRBs at maximum. Up to 682 PRBs using 10 bits (indicating a maximum of 1024 values) may indicate the PRB frequency positions of all SSBs associated with RMSI.

Optionally, in an embodiment of the present invention, the physical broadcast channel further carries third indication information, where the third indication information indicates whether the synchronization signal identifier of the first synchronization signal block is the same as the synchronization signal identifier of the second synchronization signal block.

In particular, in some possible designs, the synchronization signal identification of the first synchronization signal block may be different from the synchronization signal identification of the second synchronization signal block. In this case, it may be indicated whether the synchronization signal identification of the first synchronization signal block is identical to the synchronization signal identification of the second synchronization signal block by carrying third indication information in the physical broadcast channel.

Optionally, in an embodiment of the present invention, the physical broadcast channel further carries fourth indication information, where the fourth indication information indicates a synchronization signal identifier of the second synchronization signal block.

Specifically, in addition to indicating the resource location of the second synchronization signal block, the synchronization signal identification of the second synchronization signal block may also be indicated by carrying fourth indication information in the physical broadcast channel. For example, in the case that the synchronization signal identification of the first synchronization signal block is different from the synchronization signal identification of the second synchronization signal block, the detection complexity of the second device may be further reduced by indicating the synchronization signal identification of the second synchronization signal block through the physical broadcast channel.

By using the technical scheme, after the first synchronous signal block is detected, the second equipment can directly acquire the resource position of the second synchronous signal block, so that blind detection is not needed, and the second equipment can directly cut to the corresponding resource position for searching, thereby reducing the detection complexity of the second equipment and reducing the searching calculation time, power consumption and time delay of the second equipment.

Optionally, the first device may further indicate to the second device whether the first synchronization signal block is associated with the control information.

The manner in which the first device indicates to the second device whether the first synchronization signal block is associated with the control information may be explicit, e.g. by means of a corresponding bit indication; the transmission mode of the first synchronization signal block may be implicit, for example, and will be described below.

Optionally, in an embodiment of the present invention, the physical broadcast channel further carries second indication information, where the second indication information indicates whether the first synchronization signal block is associated with the control information.

This embodiment is an explicit indication. For example, the second indication information may be carried by a bit in a physical broadcast channel, indicating whether the first synchronization signal block is associated with the control information.

Optionally, in an embodiment of the present invention, the first device may further determine a transmission manner of the first synchronization signal block, where the transmission manner indicates whether the first synchronization signal block is associated with the control information; and transmitting the first synchronous signal block according to the transmission mode.

This embodiment is an implicit indication. The first device indicates, through different transmission modes of the first synchronization signal block, that the first synchronization signal block is associated with the control information or that the first synchronization signal block is not associated with the control information, respectively.

For example, the first device may perform the flow shown in fig. 8. In 801, it is determined whether or not a synchronization signal block is associated with control information, if so, 802 is executed, and the synchronization signal block is transmitted using a first transmission scheme, otherwise 803 is executed, and the synchronization signal block is transmitted using a second transmission scheme.

Optionally, the transmission method may include a mapping method of the synchronization signal sequence in the frequency domain, an orthogonal cover code (Orthogonal Coverage Code, OCC), a synchronization signal identifier, a cyclic redundancy check (Cyclic Redundancy Check, CRC) mask of the physical broadcast channel, or scrambling of the physical broadcast channel, which are described below, but the embodiment of the present invention is not limited thereto.

Optionally, in one embodiment of the present invention, the transmission mode of the first synchronization signal block includes a mapping mode of a synchronization signal sequence in the first synchronization signal block in a frequency domain;

The first device may:

When the first synchronous signal block is associated with the control information, determining that the mapping mode is a first mapping mode in a plurality of preset mapping modes; and/or

And when the first synchronous signal block is not related to the control information, determining that the mapping mode is a second mapping mode in the plurality of preset mapping modes.

Specifically, the first device may determine, according to whether the first synchronization signal block is associated with the control information, a mapping manner of a synchronization signal sequence in the first synchronization signal block in a frequency domain, and for association or non-association, different mapping manners are respectively adopted.

For example, the sequence of SSS or PSS may be mapped from low frequency to high frequency in two mapping manners as shown in fig. 9, and control information may be associated with the SSB; the mapping of the sequence of SSS or PSS from high frequency to low frequency to another mapping may correspond to SSB without associated control information and vice versa.

Optionally, in an embodiment of the present invention, the transmission mode of the first synchronization signal block includes a value of an orthogonal cover code modulated on a transmission symbol of the first synchronization signal block;

The first device may:

When the first synchronization signal block is associated with the control information, determining that the value of the orthogonal cover code is a first value in a plurality of preset values; and/or

And when the first synchronous signal block is not related to the control information, determining the value of the orthogonal cover code as a second value in the plurality of pre-fetch values.

Specifically, the first device may determine, according to whether the first synchronization signal block is associated with the control information, a value of an orthogonal cover code modulated on a transmission symbol of the first synchronization signal block, and for association or non-association, respectively adopt different values of orthogonal cover codes.

For example, the values of different orthogonal cover codes as shown in fig. 10 may be adopted to indicate that the first synchronization signal block is associated with the control information or that the first synchronization signal block is not associated with the control information, respectively; alternatively, the values of different orthogonal cover codes as shown in fig. 11 may be used to indicate that the first synchronization signal block is associated with the control information or that the first synchronization signal block is not associated with the control information, respectively. In fig. 10, OCC is modulated on 2 PBCH symbols, and in fig. 11, is modulated on PSS, PBCH, SSS and PBCH4 symbols, where "+" means to multiply data or symbols on all subcarriers by +1 and "-" means to multiply data or symbols on all subcarriers by "-1".

Optionally, in one embodiment of the present invention, the transmission mode of the first synchronization signal block includes a range to which the synchronization signal identifier used by the first synchronization signal block belongs;

The first device may:

Determining that a synchronization signal identity used by the first synchronization signal block belongs to a first subset when the first synchronization signal block correlates the control information; and/or

When the first synchronization signal block is not associated with the control information, it is determined that the synchronization signal identification used by the first synchronization signal block belongs to a second subset.

Specifically, in this embodiment, the synchronization signal identifiers of the two subsets may be set to respectively correspond to the associated control information or the unassociated control information. For example, the first subset may be a set of synchronization signal identifications of the synchronization signal blocks (i.e., actual synchronization signal identifications), and the second subset may be a set of synchronization signal identifications obtained by adding a predetermined value to the synchronization signal identifications in the first subset, wherein the predetermined value is greater than a difference between a maximum value and a minimum value in the first subset.

For example, if the set of actual synchronization signal identifications is { 0-503 }, the first subset may be { 0-503 }, and the second subset may be { 504-1007 }; if the actual set of synchronization signal identifications is { 0-1007 }, the first subset may be { 0-1007 }, and the second subset may be { 1008-2015 }.

The synchronization signal identifier used by the first synchronization signal block may belong to the first subset, that is, the synchronization signal identifier of the first synchronization signal block (i.e., the actual synchronization signal identifier) is adopted, or may belong to the second subset, that is, the sum of the synchronization signal identifier of the first synchronization signal block (i.e., the actual synchronization signal identifier) and a predetermined value is adopted. The two cases may correspond to associated control information or unassociated control information, respectively.

That is, the first device may:

determining that a synchronization signal identifier used by the first synchronization signal block is a synchronization signal identifier of the first synchronization signal block when the first synchronization signal block is associated with the control information, and/or determining that the synchronization signal identifier used by the first synchronization signal block is a sum of the synchronization signal identifier of the first synchronization signal block and a predetermined value when the first synchronization signal block is not associated with the control information; or alternatively

Determining that a synchronization signal identifier used by the first synchronization signal block is a sum of the synchronization signal identifier of the first synchronization signal block and a predetermined value when the control information is associated with the first synchronization signal block, and/or determining that the synchronization signal identifier used by the first synchronization signal block is the synchronization signal identifier of the first synchronization signal block when the control information is not associated with the first synchronization signal block;

For the case that the synchronization signal identifier used by the first synchronization signal block is the sum of the synchronization signal identifier of the first synchronization signal block and a predetermined value, the second device may subtract the detected synchronization signal identifier used by the first synchronization signal block by the predetermined value to obtain the synchronization signal identifier of the first synchronization signal block, so that the measurement of the neighbor cell of the initial search of the second device is not affected.

For example, if the actual synchronization signal identifier has a value ranging from {0 to 503}, the two subsets may be {0 to 503} and {504 to 1007}, respectively. Assuming that the synchronization signal of the first synchronization signal block is identified as 1, 1 may be used when the first synchronization signal block correlates with the control information; where the first synchronization signal block is not associated with the control information, 505 may be used, and the second device may derive the actual synchronization signal identity 1 by subtracting it by a predetermined value (504), or vice versa. If the actual synchronization signal identification has a value ranging from {0 to 1007}, the two subsets may be {0 to 1007} and {1008 to 2015}, respectively. Assuming that the synchronization signal of the first synchronization signal block is identified as 1, 1 may be used when the first synchronization signal block correlates with the control information; when the first synchronization signal block is not associated with the control information, 1009 may be used, and the second device may obtain the actual synchronization signal identification 1 by subtracting it by a predetermined value (1008), and vice versa.

Optionally, in one embodiment of the present invention, the transmission mode of the first synchronization signal block includes a CRC mask used by a physical broadcast channel in the first synchronization signal block;

The first device may:

Determining that the CRC mask is a first CRC mask of a plurality of predetermined CRC masks when the first synchronization signal block correlates the control information; and/or

When the first synchronization signal block is not associated with the control information, the CRC mask is determined to be a second CRC mask of the plurality of predetermined CRC masks.

Specifically, the first device may determine a CRC mask used by a physical broadcast channel in the first synchronization signal block according to whether the first synchronization signal block is associated with the control information, and employ different CRC masks for association or non-association, respectively.

For example, when the CRC length of the physical broadcast channel is 16 bits, two different CRC masks of "0000000000000000" and "0000000011111111" may be used to indicate association or non-association.

The CRC masking process is as follows:

yc(n)＝(xc(n)+sc(n))mod 2,n＝0,1,..,N-1

where N is the number of check bits of the CRC, xc represents the original CRC check bits, sc is a mask equal to the CRC, and yc is the check bits after the CRC is added.

Optionally, in one embodiment of the present invention, the transmission mode of the first synchronization signal block includes a scrambling sequence adopted by a physical broadcast channel in the first synchronization signal block;

The first device may:

Determining the scrambling sequence as a first scrambling sequence of a plurality of predetermined scrambling sequences when the first synchronization signal block correlates with the control information; and/or

And determining the scrambling sequence as a second scrambling sequence of the plurality of predetermined scrambling sequences when the first synchronization signal block is not associated with the control information.

Specifically, the first device may determine, according to whether the first synchronization signal block is associated with the control information, a scrambling sequence adopted by a physical broadcast channel in the first synchronization signal block, and respectively adopt different scrambling sequences for association or non-association.

For example, information or coded bits before or after physical broadcast channel coding may be correspondingly scrambled. Different sequences are used to correspond to different states (associated or not). The scrambling process may be as follows:

y(n)＝(x(n)+s(n))mod 2,n＝0,1,..,L-1

Wherein L is the information or code bit length of the physical broadcast channel, x is the information or code bit of the physical broadcast channel before scrambling, s is the scrambling sequence, and y is the information or code bit of the physical broadcast channel after scrambling. Different s are generated according to different states. Different states may correspond to different scrambling sequences, or may correspond to initial values of different scrambling sequences.

By adopting the technical scheme, the second equipment only needs to detect the actual transmission mode of the first synchronous signal block, so as to determine whether the first synchronous signal block is associated with control information or not, and no blind detection of a physical broadcast channel is needed, thereby reducing the detection complexity of the second equipment and reducing the power consumption and time delay of the second equipment.

The second device obtains the first indication information carried by the physical broadcast channel in the first synchronization signal block 630.

On the receiving side, the second device receives the first synchronization signal block and acquires the first indication information therein, so that the resource position of the second synchronization signal block can be directly known.

Optionally, the second device may also first determine whether the first synchronization signal block is associated with the control information. And when the first synchronous signal block is determined not to be associated with the control information, acquiring first indication information carried by a physical broadcast channel in the first synchronous signal block. And receiving the control information according to the first synchronous signal block when the first synchronous signal block is determined to be related to the control information.
