Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure. The communication system may include, but is not limited to, one or more network devices and one or more terminal devices, such as a network device 101 and a terminal device 102 in fig. 1, where the network device 101 in fig. 1 is a base station, the terminal device 102 is a handset, and the terminal device 102 may establish a wireless link with the network device 101 for communication.

In the communication system shown in fig. 1, a network device may send multicast or broadcast data to a terminal device through a first PDSCH, where a first PRB bundling size of the first PDSCH may be preset, or the terminal device may determine according to indication information sent by the network device.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining a bundling size according to an embodiment of the present application, where the method for determining a bundling size is applicable to the communication system shown in fig. 1, and is explained from the perspective of interaction between a network device and a terminal device. Optionally, if the first PRB bundling size of the first PDSCH is determined according to indication information sent by the network device, the method for determining the bundling size further includes step S201, and the following steps are respectively described:

s201, a network device sends indication information to a terminal device, wherein the indication information is used for determining a first Physical Resource Block (PRB) bundling size of a first Physical Downlink Shared Channel (PDSCH), and the first PDSCH carries multicast or broadcast service data.

S202, the terminal equipment determines a first Physical Resource Block (PRB) bundling size of a first Physical Downlink Shared Channel (PDSCH), the first PDSCH bears multicast or broadcast service data, and the first PRB bundling size is a preset bundling size or a bundling size determined according to indication information.

In this embodiment of the present application, the first PDSCH is a PDSCH carrying multicast or broadcast service data, the first PDSCH may be a group common-common PDSCH, the first PDSCH may be scheduled or activated by a first PDCCH, CRC of the first PDCCH is scrambled by a first Radio Network Temporary Identity (RNTI), the first RNTI may be an RNTI allocated by a Network device to a terminal device for transmitting MBS, optionally, the first RNTI may be a G-RNTI or a G-CS-RNTI, and the specific naming of the first RNTI is not limited in this application.

The PRB bundling size (PRB bundling size) of the present application refers to bundling a certain number of PRBs together to form a physical resource block bundle (PRB bundle), for example, the PRB bundling size is 2, which refers to bundling 2 PRBs together to form one physical resource block bundle. The terminal device and/or the network device may assume the same precoding (precoding) to apply to the PRBs in the same physical resource block binding.

The first PRB bundling size of the first PDSCH refers to the number of PRBs included in one physical resource block bundling when bundling at least one PRB in a PRB set, where the at least one PRB in the PRB set is a PRB for transmitting the first PDSCH. Optionally, if the network device configures the first Frequency-domain Resource or the related configuration for transmitting the MBS, the PRB in the PRB set may be a PRB Resource in the configured first Frequency-domain Resource, such as the network device configures a Common Frequency-domain Resource (CFR) for the MBS, the PRB in the PRB set may be a PRB Resource in a CFR, and the network device may configure the CFR through CFR configuration information, it should be noted that the first Frequency-domain Resource or the related configuration configured by the network device for transmitting the MBS may not be named as a CFR, where the CFR is merely an example, and the corresponding configuration information for configuring the CFR may also not be named as CFR configuration information.

In a first optional embodiment, the first PRB bundling size of the first PDSCH may be a preset bundling size, for example, the protocol specifies a group-common PDSCH carrying multicast or broadcast traffic data with a bundling size of 2, and it may be understood that other values may also be used, such as 4 or wideband. The terminal device may determine a preset bundling size as a first PRB bundling size of the first PDSCH.

In a second alternative embodiment, the first PRB bundle size of the first PDSCH may be determined according to indication information sent by the network device, where the indication information is used to directly or indirectly indicate the first PRB bundle size, and the following is respectively set forth in a first manner and a second manner:

first, the indication information may include a first PRB bundling size of the first PDSCH, which may be 2 or 4 or wideband, where wideband refers to bundling all PRBs used for transmitting the first PDSCH together into physical resource block bundling.

Optionally, the indication Information including the first PRB bundling size may be sent through Downlink Control Information (DCI), where the DCI may be carried by a first PDCCH, the CRC of the first PDCCH may be scrambled by a first RNTI, the first RNTI may be an RNTI allocated by a network device to a terminal device for transmitting an MBS, and optionally, the first RNTI may be a G-RNTI or a G-CS-RNTI. It can be appreciated that if the first PRB bundling size is indicated through the DCI, the PRB bundling type in the higher layer configuration information, which may be CFR configuration information, should be configured as dynamic bundling. Optionally, the field name for carrying the PRB Bundling Type may be PRB-Bundling Type, and of course, may also be other names, for example, the field name may be PRB-Bundling Type-r17, and this application is not limited in this application. The name of the specific dynamic content binding in the field may be dynamic bundling, and may also be other names, such as dynamic bundling-r17, which is not limited in this application.

Optionally, the indication information including the first PRB bundling size may also be indicated by a higher layer parameter, that is, the higher layer parameter includes the first PRB bundling size, where the name of the higher layer parameter is not limited, and may be, for example, bundling size or bundling size-r 17. It is understood that, if the first PRB bundling size is indicated by the higher layer parameter, the PRB bundling type in the higher layer configuration information should be configured as static bundling, that is, the content of the field for carrying the PRB bundling type is static bundling, and the name of the static bundling is not limited, such as static bundling or static bundling-r17.

For example, the terminal device may not expect the PRB bundling type to be configured as dynamic bundling, i.e. the first PRB bundling size is indicated by the higher layer parameter and not dynamically indicated, e.g. by DCI.

In the second mode, the first PRB bundling size of the first PDSCH may be indirectly determined through a state value of the indication information, which may also be referred to as a value of the indication information. For example, the indication information is at least one bit in a certain field, and the state value of the indication information may be a value of the at least one bit. For example, the field may be a bundling size indicator field in a DCI, the field may include a bit, a status value of the indication information may be a value of 0 or 1, optionally, the DCI may be carried by a first PDCCH, and the CRC of the first PDCCH is scrambled by a first RNTI, where the first RNTI may be an RNTI allocated by the network device to the terminal device for transmitting the MBS, and optionally, the first RNTI may be a G-RNTI or a G-CS-RNTI, which is not limited by the specific naming of the application, and the first PDSCH may be scheduled or activated by the first PDCCH.

Specifically, optionally, different state values of the indication information may correspond to different bundling size sets, where the bundling size set includes at least one PRB bundling size, for example, if the state value of the indication information is a first state value, the first bundling size set may include one or two PRB bundling sizes. And if the state value of the indication information is a second state value, corresponding to a second bundling size set, wherein the second bundling size set comprises a PRB bundling size, and the first bundling size set and the second bundling size set can be configured by a higher layer. The first state value may be 1, the second state value may be 0, and it is understood that, if the indication information includes a plurality of bits, the first state value may be a value of the plurality of bits, for example, the indication information includes 2 bits, the first state value may be 01, and the second state value may be 11, which is not limited in this application.

The terminal device may determine a bundling size in the second bundling size set as the first PRB bundling size if the state value of the indication information is the second state value. If the state value of the indication information is a first state value and the first bundling size set comprises a PRB bundling size, determining the PRB bundling size as the first PRB bundling size; if the state value of the indication information is the first state value and the first bundling size set includes two PRB bundling sizes, it may be further determined whether the PRB set satisfies a target condition, where the PRB set includes at least one PRB used for transmitting the first PDSCH, if the PRB set satisfies the target condition, a preset bundling size in the first bundling size set may be determined as the first PRB bundling size, and if the PRB set does not satisfy the target condition, one bundling size in the first bundling size set except the preset bundling size may be determined as the first PRB bundling size, and optionally, the preset bundling size may be a wideband. For example, the first bundling size set may be (2, wideband) or (4, wideband), and if the PRB set satisfies the target condition, the first PRB bundling size is wideband, and if the PRB set does not satisfy the target condition, the first PRB bundling size is 2 or 4.

Optionally, if the network device configures a first frequency-domain resource, such as a CFR, for transmitting the MBS, and the PRBs in the set of PRBs are in the first frequency-domain resource, the target condition may include: all PRBs in the PRB set are continuous, and the number of PRBs in the PRB set is greater than half of the total number of PRBs of the first frequency domain resource where the first PDSCH is located. Optionally, if the network device does not configure the first frequency domain resource, such as not configure the CFR, the target condition may include: all PRBs in the PRB set are continuous, and the number of PRBs in the PRB set is greater than half of the total number of PRBs of a wideband Part (BWP) in which the first PDSCH is located.

Optionally, the terminal device does not expect that the first bundling size set includes two PRB bundling sizes, that is, the first bundling size set includes only one PRB bundling size, but does not include two PRB bundling sizes, when the state value of the indication information is a first state value, the PRB bundling size in the first bundling size set may be directly used as the first PRB bundling size, and when the state value of the indication information is a second state value, the PRB bundling size in the second bundling size set may be directly used as the first bundling PRB size.

It is to be understood that, in the design of indirectly indicating the first PRB bundling size through the indication information in the second manner, the PRB bundling type of the higher layer configuration information may be configured to be dynamically bundled, and optionally, the higher layer configuration information may be configuration information of the first frequency domain resource, such as CFR configuration information.

Alternatively, if the network device is not configured with the first frequency domain resource, such as not configured with the CFR, the first PRB bundling size of the first PDSCH may be preset.

In the embodiment of the present application, a first PRB bundling size of a first PDSCH carrying multicast or broadcast service data may be preset, or the first PRB bundling size of the first PDSCH may be determined through indication information of a network device, so as to implement determination of the bundling size of the first PDSCH carrying multicast or broadcast service data.
