All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for indicating a bundling size of a physical resource block according to an embodiment of the present invention, and the method is applied to the wireless communication system shown in fig. 1. As shown in fig. 2, the method includes the following steps.

S210, the network equipment sends downlink control information DCI.

When the higher layer parameter PRB-Bundling Type is configured as dynamic Bundling, the PRB Bundling size is indicated by Downlink Control Information (DCI). The network equipment sends DCI to the terminal equipment, and indicates the PRB bundling size which can be used by the terminal equipment through the DCI.

In the embodiment of the present application, when the higher layer parameter PRB-Bundling Type is configured as dynamic Bundling, the network device may configure 3 sets of Bundling sizes, that is, a first set of Bundling sizes (PRB Bundling sizes), a second set of Bundling sizes, and a third set of Bundling sizes, through higher layer signaling.

Wherein the third set of bundling sizes is different from both the first set of bundling sizes and the second set of bundling sizes, the first set of bundling sizes and the second set of bundling sizes configured by higher layer signaling.

For example, the third set of bundling sizes may also be configured as non-network high layer information, i.e. the third set of bundling sizes are defined by the protocol. That is, the network device may configure 2 bundling sizes, i.e., the first bundling size and the second bundling size, through higher layer signaling, and a third bundling size is defined in the protocol.

Specifically, the first set of bundling sizes may include one or 2 bundling sizes, the second set of bundling sizes includes one bundling size, and the third set of bundling sizes may include one or more bundling sizes. For example, the third set of bundling sizes may include at least one of the following information: 1 Resource Block (RB), 2 RBs, 4 RBs, 6 REs, etc., without limitation.

For example, the network device may also configure the terminal device with one or more physical resource block bundling sizes predefined in the protocol. For example, the network device pre-configures one RB or 6 REs to the terminal device through Radio Resource Control (RRC) signaling, and when the network device indicates that the terminal device physical Resource block bundling size is the pre-configured physical Resource block bundling size, the terminal device may select a physical Resource block bundling size to use from the pre-configured one or more physical Resource block bundling sizes.

S220, the terminal equipment receives the downlink control information DCI and determines the physical resource block bundling size of the physical downlink shared channel PDSCH and/or the physical uplink shared channel PUSCH according to the DCI.

In the embodiment of the application, the terminal device determines the bundling size of the physical resource block according to the indication of the network device. For example, when the DCI indicates that the physical resource block bundling size is a bundling size in a first set of bundling sizes, the terminal device determines the physical resource block bundling size from the first set of bundling sizes; when the DCI indicates that the physical resource block bundling size is a bundling size in a second set of bundling sizes, the terminal equipment determines the physical resource block bundling size from the second set of bundling sizes; when the DCI indicates that the physical resource block bundling size is a third set of bundling sizes, the terminal device determines the physical resource block bundling size from the third set of bundling sizes.

For example, when the DCI indicates that the physical resource block bundling size is a pre-configured or predefined bundling size for the network device, the terminal device determines the physical resource block bundling size from one or more pre-configured or predefined bundling sizes. In the present application, the bundling size of the Physical resource block may be applicable to a Physical Downlink Shared Channel (PDSCH) and/or a Physical Uplink Shared Channel (PUSCH) scheduled and/or activated by the DCI.

It can be seen that, in the method for indicating the physical resource block bundling size provided in the embodiment of the present application, the terminal device receives the downlink control information DCI, and determines the physical resource block bundling size of the physical downlink shared channel PDSCH and/or the physical uplink shared channel PUSCH according to the DCI, so as to dynamically indicate the physical resource block bundling size.

Referring to fig. 3, fig. 3 is a flowchart illustrating another method for indicating a bundling size of a physical resource block according to an embodiment of the present application, and the method is applied to the wireless communication system shown in fig. 1. As shown in fig. 3, the method includes the following steps.

S310, the network equipment sends Downlink Control Information (DCI), wherein the DCI comprises a first bit field, the first bit field is used for indicating whether a first field in the DCI is effective, and the first field is used for indicating the physical resource block bundling size of the PDSCH and/or the PUSCH.

Wherein the PRB Bundling size is indicated by the DCI when the higher layer parameter PRB-Bundling Type is configured as dynamic Bundling. The network equipment sends DCI to the terminal equipment, and indicates the PRB bundling size which can be used by the terminal equipment through the DCI.

In the embodiment of the present application, when the higher layer parameter prb-Bundling Type is configured as dynamic Bundling, the network device may configure 3 sets of Bundling sizes, that is, the first set of Bundling sizes, the second set of Bundling sizes, and the third set of Bundling sizes, through higher layer signaling.

For example, the third set of bundling sizes may also be configured by non-network high layer information, i.e. the third set of bundling sizes are defined by the protocol. That is, the network device may configure 2 bundling sizes, i.e., the first bundling size and the second bundling size, through higher layer signaling, and a third bundling size is defined in the protocol.

Wherein the third set of bundling sizes is different from both the first set of bundling sizes and the second set of bundling sizes, and the first set of bundling sizes and the second set of bundling sizes are configured by higher layer signaling.

Specifically, the first set of bundling sizes may include one or 2 bundling sizes, the second set of bundling sizes includes one bundling size, and the third set of bundling sizes may include one or more bundling sizes. Illustratively, the third set of bundling dimensions may include at least one of: 1 RB, 2 RB, 4 RB, 6 RE, etc., without limitation.

For example, the network device may also configure the terminal device with one or more physical resource block bundling sizes predefined in the protocol. For example, the network device pre-configures a bundling size of one RB or 6 REs to the terminal device through RRC signaling, and when the network device indicates that the terminal device physical resource block bundling size is the pre-configured physical resource block bundling size, the terminal device may select a physical resource block bundling size to use from the pre-configured one or more physical resource block bundling sizes.

The first field is a PRB bundling size indicator field, and the PRB bundling size indicator field is used for indicating a physical resource block bundling size. When the value of the PRB bundling size indicator field is 0, the terminal device may determine that the physical resource block bundling size is the bundling size in the second set of bundling sizes. When the value of a PRB bundling size indicator field is 1, if only 1 bundling size is configured for a first set of bundling sizes, the terminal device may determine that the physical resource block bundling size is the bundling size in the first set of bundling sizes; if the first set of bundling sizes configures 2 bundling sizes, and when the scheduled PRBs are consecutive and the number of the scheduled PRBs is greater than half of the number of the PRBs of the BWP where the scheduled PRBs are located, the terminal device may determine that the physical resource block bundling size is a wideband, that is, the same as the bandwidth of the scheduled PRBs; otherwise the terminal device may determine the physical resource block bundling size to be 2 RBs or 4 RBs in the first set of bundling sizes.

In the embodiment of the present application, the network device newly defines a first bit field in the DCI, where the first bit field is used to indicate whether a PRB bundling size indicator field in the DCI is valid. The first bit field is 1bit, and the 1bit may be an additional 1bit in the DCI, or an existing 1bit in the DCI, for example, if the 1bit in the reserved field in the DCI is set as the first bit field, this is not limited in the embodiment of the present application.

Optionally, if the value of the first bit field is a first value, the first bit field indicates that a first field in the DCI is valid; and if the first bit field value is a second value, the first bit field indicates that the first field in the DCI is invalid.

Wherein the first value can be 1 or 0. When the first value is 1, the second value is 0; when the second value is 0, the first value is 1. For example, when the value of the first bit field is 0, the first bit field is used to indicate that the PRB bundling size indicator field is valid; and when the value of the first bit field is 1, the first bit field is used for indicating that the PRB bundling size indicator field is invalid. For example, when the value of the first bit field is 1, the first bit field is used to indicate that the PRB bundling size indicator field is valid; and when the value of the first bit field is 0, the first bit field is used for indicating that the PRB bundling size indicator field is invalid.

It should be noted that, the name of the field specifying the PRB bundling size in the DCI in the current standard is the PRB bundling size indicator field, but names specifying the same meaning in other standards are also applicable to this application, that is, this application does not limit the names of these parameters.

S320, the terminal equipment receives the downlink control information DCI and determines the physical resource block bundling size of the physical downlink shared channel PDSCH and/or the physical uplink shared channel PUSCH according to the DCI.

In the embodiment of the application, the terminal device determines the bundling size of the physical resource block according to the indication of the network device. The physical resource block bundling size may be applicable to PDSCH and/or PUSCH scheduled and/or activated by DCI.

Optionally, the determining, by the terminal device, the physical resource block bundling size of the PDSCH and/or the PUSCH according to the DCI includes: if the first field in the DCI is invalid, the terminal device determines that the physical resource block bundling size of the PDSCH and/or PUSCH is a bundling size in a third set of bundling sizes, where the third set of bundling sizes includes at least one physical resource block bundling size defined by a higher layer configuration or a protocol.

Specifically, when the first bit field indicates that the PRB bundling size indicator field is valid, the terminal device may obtain a physical resource block bundling size of the PDSCH and/or the PUSCH according to the indication of the PRB bundling size indicator field. When the first bit field indicates that the PRB bundling size indicator field is invalid, the terminal device may determine that a physical resource block bundling size of the PDSCH and/or PUSCH is a bundling size in the third set of bundling sizes. For example, when the first bit field takes a value of 0 and indicates that the PRB bundling size indicator field is invalid, the terminal device may determine that the physical resource block bundling size of the PDSCH and/or PUSCH is 1 RB or 6 REs.

For example, when the first bit field indicates that the PRB bundling size indicator field is invalid, the terminal device may determine a physical resource block bundling size of the PDSCH and/or PUSCH as a bundling size in a third set of bundling sizes defined in the protocol.

In the embodiment of the application, the terminal device indicates the physical resource block bundling size of the PDSCH and/or the PUSCH according to the newly defined first bit field in the DCI, can determine the physical resource block bundling size, introduces a new bundling size, and can dynamically indicate the physical resource block bundling size.

Referring to fig. 4, fig. 4 is a flowchart illustrating another method for indicating a bundling size of a physical resource block according to an embodiment of the present application, and the method is applied to the wireless communication system shown in fig. 1. As shown in fig. 4, the method includes the following steps.

S410, the network equipment sends Downlink Control Information (DCI), wherein the DCI comprises a first bit field, the first bit field is used for indicating whether a first field in the DCI is effective, and the first field is used for indicating the physical resource block bundling size of the PDSCH and/or the PUSCH.

For example, the network device may also configure the terminal device with one or more physical resource block bundling sizes predefined in the protocol. For example, the network device pre-configures one RB or 6 REs to the terminal device through RRC signaling, and when the network device indicates that the terminal device physical resource block bundling size is the pre-configured physical resource block bundling size, the terminal device may select a physical resource block bundling size to use from the pre-configured one or more physical resource block bundling sizes.

The first field is a PRB bundling size indicator field, and the PRB bundling size indicator field is used for indicating a physical resource block bundling size. When the value of the PRB bundling size indicator field is 0, the terminal device may determine that the physical resource block bundling size of the PDSCH and/or the PUSCH is the bundling size in the second set of bundling sizes. When the value of a PRB bundling size indicator field is 1, if only 1 bundling size is configured for a first set of bundling sizes, the terminal device may determine that the physical resource block bundling size of the PDSCH and/or the PUSCH is the bundling size in the first set of bundling sizes; if the first set of bundling sizes configures 2 bundling sizes, and when the scheduled PRBs are consecutive and the number of the scheduled PRBs is greater than half of the number of the PRBs of the BWP where the first set of bundling sizes is located, the terminal device may determine that the physical resource block bundling size of the PDSCH and/or the PUSCH is a wideband, that is, the same as the bandwidth of the scheduled PRBs; otherwise, the terminal device may determine the physical resource block bundling size of the PDSCH and/or PUSCH to be 2 RBs or 4 RBs in the first set of bundling sizes.

In the embodiment of the present application, the network device newly defines a first bit field and a second bit field in the DCI, where the first bit field is used to indicate whether a PRB bundling size indicator field in the DCI is valid, and the second bit field is used to indicate a physical resource block bundling size of the PDSCH and/or PUSCH when the first bit field indicates that the PRB bundling size indicator field is invalid. The first bit field and the second bit field may be both 1bit, that is, 2bit, where the 2bit may be an additional 2bit added in the DCI, or may also be an existing 2bit in the DCI, and for example, the 2bit in the reserved field in the DCI is set as the first bit field and the second bit field, which is not limited in this embodiment of the present application.

Wherein, the first value can be 1 or 0. When the first value is 1, the second value is 0; when the second value is 0, the first value is 1. For example, when the value of the first bit field is 0, the first bit field is used to indicate that the PRB bundling size indicator field is valid; and when the value of the first bit field is 1, the first bit field is used for indicating that the PRB bundling size indicator field is invalid. For example, when the value of the first bit field is 1, the first bit field is used to indicate that the PRB bundling size indicator field is valid; and when the value of the first bit field is 0, the first bit field is used for indicating that the PRB bundling size indicator field is invalid.

Further, when the first bit field indicates that the PRB bundling size indicator field is invalid, the second bit field is valid, and the second bit field is used for indicating the physical resource block bundling size of the PDSCH and/or PUSCH.

S420, the terminal equipment receives the downlink control information DCI and determines the physical resource block bundling size of the physical downlink shared channel PDSCH and/or the physical uplink shared channel PUSCH according to the DCI.

Specifically, when the first bit field indicates that the PRB bundling size indicator field is valid, the terminal device may obtain a physical resource block bundling size of the PDSCH and/or the PUSCH according to the indication of the PRB bundling size indicator field. When the first bit field indicates that the PRB bundling size indicator field is invalid, the terminal device may determine the physical resource block bundling size of the PDSCH and/or PUSCH according to the second bit field. For example, when the first bit field value is 0 and indicates that the PRB bundling size indicator field is invalid, if the second bit field value is 1, the terminal device may determine that the physical resource block bundling size of the PDSCH and/or PUSCH is a bundling size in a third set of bundling sizes, such as 1 RB or 6 REs; if the second bit field value is 0, the terminal device may determine that the physical resource block bundling size of the PDSCH and/or the PUSCH is a preconfigured or predefined bundling size, or the terminal device may determine that the physical resource block bundling size of the PDSCH and/or the PUSCH is a bundling size in a third set of bundling sizes, such as 1 RB or 6 REs.

For example, when the first bit field indicates that the PRB bundling size indicator field is invalid, the terminal device may determine the physical resource block bundling size of the PDSCH and/or PUSCH according to the second bit field as a bundling size in a third set of bundling sizes defined in the protocol, such as 1 RB or 6 REs.

It should be noted that, the name of the field indicating the PRB bundling size in the DCI specified in the current standard is a PRB bundling size indicator field, but names specifying the same meaning in other standards are also applicable to the present application, that is, the present application does not limit the names of these parameters.

That is, the network device may configure 2 bundling sizes, i.e., the first bundling size and the second bundling size, through high layer signaling, and a third bundling size is defined in the protocol.

Wherein the first value may be 1 or 0. When the first value is 1, the second value is 0; when the second value is 0, the first value is 1.
