The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
In order to better understand the embodiments of the present application, the following terms refer to the embodiments of the present application:

RNTI: radio Network Temporary identity
C-RNTI: cell RNTI cell radio network temporary identifier
G-RNTI: group RNTI group radio network temporary identifier

MAC CE: multiple Access Channel control element MAC control unit
In LTE release 8/9, multicast service transmission is implemented by a multicast single frequency network (MBSFN) transmission mechanism, and multiple cells need to schedule the same service on the same time-frequency domain resource synchronously, because the time-frequency domain resource is reserved, even if there is not so many data scheduling, it cannot be used for other data transmission, so the MBSFN mechanism causes serious resource waste. A single cell point-to-multipoint (SC-PTM) transmission mechanism is introduced for broadcast multicast services at Release 14. The UE interested in the broadcast multicast service in one cell can receive the dynamically scheduled broadcast multicast service according to the configuration information, and different cells can flexibly and dynamically schedule the broadcast multicast service without synchronization.
In LTE, a plurality of channels are introduced, a Multicast Control Channel (MCCH) is used for bearing configuration information of broadcast multicast service, a Multicast Traffic Channel (MTCH) is used for bearing scheduling data of the broadcast multicast service, and the MCCH and the MTCH are mapped on a physical shared channel (DSCH). Introducing a plurality of Radio Network Temporary Identifiers (RNTIs) for scrambling different data to be scheduled, using a single cell radio network temporary identifier (SC-RNTI) for scrambling a physical control channel (PDCCH) and scheduled MCCH data, using a group radio network temporary identifier (G-RNTI) for scrambling the PDCCH and scheduled MTCH data, associating one G-RNTI with each broadcast multicast service, and selectively receiving different broadcast multicast services by the UE.
The SC-PTM broadcast multicast transmission mechanism shares the whole resource with the unicast service, and the base station dynamically schedules and supports the transmission of the broadcast multicast service and the unicast service in the same slot.
Partial carrier Bandwidth (BWP): in the 5G system, terminals with different bandwidth reception capabilities are supported. In order to support terminals of different bandwidth capabilities, the 3GPP organization proposes the definition of partial carrier Bandwidths (BWPs), each BWP having the following Numerology characteristics: subcarrier spacing, CP type, frequency domain location, bandwidth length. Meanwhile, in order to save power consumption of the terminal, after the terminal device and the network device complete RRC connection, the network device configures one or more BWPs for the terminal according to bandwidth receiving capability of the terminal device and service requirements. These BWPs need to be limited to the maximum reception bandwidth of the UE. The terminal/network can adaptively adjust the used BWP according to the service requirement and the load condition of the terminal, the activation and deactivation of the BWP can be carried out through RRC signaling or scheduling DCI, if the BWP ID is changed in the scheduling DCI, the UE needs to carry out BWP conversion, the radio frequency center frequency point is converted to the indicated new BWP, and data is transmitted and received on the new BWP according to the resource position indicated by the DCI.
And (3) broadcast multicast: starting from release R17 to support NR broadcast multicast service, LTE may be seen as having only one BWP, but in NR the base station will configure UE with different BWPs, including same or different BWP number, same or different BWP position, same or different BWP subcarrier spacing, same or different BWP bandwidth length, and only one BWP is active at a time.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a multicast service resource indication system according to an embodiment of the present invention, as shown in fig. 1, a system architecture diagram 100 of model management includes network devices 101 and terminal devices 102, the number of the terminal devices 102 is not limited to one, the network devices 101 and the terminal devices 102 can be in communication connection, and the connection mode includes a wired connection and a wireless connection.

The network device 101 indicates a first target MBS BWP identifier in the first BWP set to the terminal device 102 (the first terminal device) according to the MBS BWP set configuration as the first BWP set, and sends a first indication message carrying the first target MBS BWP identifier to the terminal device 102, where the first indication message is used to indicate the terminal device 102 to receive MBS data according to the BWP indicated by the first target MBS BWP identifier, so that the terminal device in the non-connected state or the non-activated state can also receive the MBS service; further, the network device 101 configures a second BWP set corresponding to the unicast partial carrier bandwidth BWP for the terminal device 102 (second terminal device) interested in the MBS data, determines a second target MBS BWP identifier according to the first BWP set and the second BWP set, and sends a second indication message carrying the second target MBS BWP identifier to the terminal device 102, where the second indication message is used to indicate the terminal device 102 to receive the MBS data according to the BWP indicated by the second target MBS BWP identifier, and the network device uses the BWP corresponding to the overlay identifier (second target MBS BWP identifier) without performing corresponding conversion on the BWP to support transmission of the multicast service, and meanwhile, improves transmission efficiency of the multicast service.

Referring to fig. 2, fig. 2 is a method for indicating multicast service resources disclosed in the embodiment of the present application, where the method mainly uses a network device as an execution subject to perform related explanation, and specifically includes the following steps:
s201, the network device configures an MBS BWP set as a first BWP set.
The network device (such as a base station) configures an MBS BWP set for the terminal device through a system message or a Multicast Control Channel (MCCH), and each MBS BWP in the MBS BWP set has a corresponding MBS BWP identifier. The terminal device herein may include a terminal device in a connected state, and may also include a terminal device in a non-connected state or a non-activated state, and the number of the terminal devices is not limited. The MBS BWP is aggregated with one or more MBS BWPs, the number of MBS BWPs configured for each terminal device may be the same or different, the locations of the MBS BWPs may be the same or different, and the subcarrier intervals of the MBS BWPs may be the same or different. For the sake of convenience of differentiation, the embodiments of the present application name this MBS BWP set as the first BWP set. In one embodiment, the first BWP set may be indicated by way of system information.
In a possible implementation manner, after configuring the first BWP set for the terminal device through the system message or the multicast control channel, the network device further needs to configure a corresponding control resource set CORESET and a common search space CSS for each BWP in the first BWP set, so that the terminal device can monitor a Physical Downlink Control Channel (PDCCH) scheduled by the MBS according to the CORESET and the CSS. Wherein, the CORESET and the CSS are both used for determining the corresponding specific position of the MBS in the frequency domain. Further, parameter set numerology used by each BWP is also included in the first BWP set, and is used to indicate subcarrier spacing, CP type, frequency domain position, and bandwidth length, etc. In some possible implementations, one or more BWPs in the first BWP set correspond to one parameter set numerology, and each BWP in the first BWP set is configured with a control resource set CORESET and a common search space CSS.
S202, the network device indicates the first target MBS BWP identification in the first BWP set to the first terminal device, and sends a first indication message carrying the first target MBS BWP identification to the first terminal device, wherein the first indication message is used for indicating the first terminal device to receive MBS data according to the BWP indicated by the first target MBS BWP identification.
The first terminal device is mainly used for exemplarily indicating that the terminal device is in an idle state or an inactive state. Step S202 is mainly for the network device to determine a BWP for the idle or inactive terminal device to receive MBS data, so that the idle or inactive terminal device may also receive MBS data.
In a possible implementation manner, the network device indicates, to the first terminal device, the first target MBS BWP identifier in the first BWP set, which may specifically be: the network device selects a first BWP or a preset nth BWP in the first BWP set, and indicates the first BWP or the preset nth BWP in the first BWP set as the first target MBS BWP identifier to the first terminal device. Specifically, the method comprises the following steps. The network device configures an identification list of corresponding MBS BWPs for each SCS in SIB or MCCH, each MBS BWP corresponds to an identification (common index), in this case, the network device selects the MBS BWP identifier corresponding to the first BWP in the list as the first target MBS BWP identifier (in this case, mostly default, if the network device does not specify BWP, the mode is defaulted), or the network device selects the MBS BWP identifier corresponding to the nth BWP in the list as the first target MBS BWP identifier, wherein N is an integer greater than 1, mainly for distinguishing between the first BWP and the second BWP, the preset nth BWP may be specifically set according to the requirement of a developer, or may be determined according to a preset condition, where the preset condition may be a bandwidth or a subcarrier interval corresponding to the BWP. Specifically, as shown in fig. 3a, in the protocol, a parameter point a is defined, which points to a position where the starting RB of the CRB is 0, so that all positions in the subsequent BWP are obtained by relative displacement of this position. In one example, when the subcarrier spacing SCS is 15KHz, the Initial DL BWP (Initial downlink BWP), the Default MBS BWP (Default MBS DWP), and the MBS BWP N (nth MBS BWP) may be included in the corresponding set; in another example, when SCS is 30KHz, the respective set may include MBS BWP1, MBS BWP2, and MBS BWP M.
Further, after determining the first target MBS BWP identifier, the network device sends a first indication message carrying the first target MBS BWP identifier to the first terminal device, where the indication message is mainly used to indicate that the first terminal device can receive MBS data according to the BWP indicated by the first target MBS BWP identifier.
S203, the network device configures a second BWP set corresponding to the unicast partial carrier bandwidth BWP for the MBS data-interested second terminal device, and determines a second target MBS BWP identification according to the first BWP set and the second BWP set.
The second terminal device is mainly used for exemplarily indicating that the terminal device is a terminal device in a connected state with the network device, and similarly, the number of the second terminal devices is multiple. Step S203 is mainly to determine the second target MBS BWP identifier from the overlapped BWPs in the first BWP set and the second BWP set, so that the network device can send MBS data to the terminal device without performing BWP conversion.
In a possible implementation manner, before the network device configures a second BWP set corresponding to the unicast partial carrier bandwidth BWP for a second terminal device interested in MBS data, the network device may further receive request information sent by the second terminal device, where the request information is mainly used to indicate that the second terminal device is interested in MBS data, or when the second terminal device establishes a connection with the network, the second terminal device carries the request information through an RRC signaling message, so that the network device knows that the second terminal device is interested in MBS data according to the request information, that is, the second terminal device wants to receive MBS data sent by the network device.
In a possible implementation manner, the network device configures a second BWP set corresponding to the unicast partial carrier bandwidth BWP for the MBS data interested second terminal device, specifically: the network device configures a second BWP set corresponding to the unicast partial carrier bandwidth BWP for the second terminal device according to the first BWP set configured in step S202, where each BWP in the second BWP set also corresponds to a BWP id. The BWP frequency domain in the second BWP set contains the BWPs in the first BWP set because, for a large broadband terminal device, its unicast BWP band is larger than the MBS BWP band. Specifically, as shown in fig. 3b, based on the subcarrier spacing SCS1 of MBS BWP1, the corresponding BWP at UE1, BWP at UE2, and BWP at UE3 all overlap MBS BWP1, and based on the subcarrier spacing SCS2 of MBS BWP2, the corresponding BWP at UE4, BWP at UE5, and BWP at UE6 all overlap MBS BWP 2. Each BWP in the second BWP set is also configured with a corresponding core set and a CSS, so that the second terminal device can monitor the PDCCH scheduled by the BMS according to the core set and the CSS. In some possible embodiments, one or more BWPs in the second BWP set correspond to one parameter set numerology. Wherein one BWP in the second BWP set and one or more BWPs in the first BWP set overlap in frequency domain.
Further, the network device determines, according to the first BWP set and the second BWP set, a second target MBS BWP identifier, which specifically is: the network device determines an overlapped first BWP identification set according to the first BWP set and the second BWP set, where the obtained overlapped first BWP identification indicates that the BWP identification is the identification of the corresponding BWP in the first BWP set, and the overlap indicates that there is a frequency domain overlap portion between the MBS BWP of the first BWP set and the BWP in the second BWP set. Specifically, as shown in fig. 3b, since BWP of UE1, BWP of UE2, and BWP of UE3 all overlap MBS BWP1, the identity corresponding to MBS BWP1 may be identified as one BWP in the overlapping first BWP identity set. Further, the network device selects one BWP identifier from the overlapped first BWP identifier sets as the second target MBS BWP identifier, which may specifically be: the network device selects a first BWP identifier or a preset mth BWP identifier from the overlapped first BWP identifier set, and takes the BWP identifier corresponding to the first BWP identifier or the preset mth BWP identifier as a second target MBS BWP identifier, where M is an integer greater than 1. It should be noted that, if the network device does not set the preset mth BWP identifier, the network device defaults that the first BWP identifier in the overlapped first BWP identifier set is the second target MBS BWP identifier.
S204, the network device sends a second indication message carrying the second target MBS BWP identification to the second terminal device, and the second indication message is used for indicating the second terminal device to receive MBS data according to the BWP indicated by the second target MBS BWP identification.
In a possible implementation manner, after determining the second target MBS BWP identifier, the network device sends a second indication message carrying the second target MBS BWP identifier to the terminal device, where the second indication message is mainly used to indicate that the second terminal device can receive MBS data according to the BWP indicated by the second target MBS BWP identifier.
In one possible implementation, the second indication message may be a UE-specific RRC signaling indication message.
In a possible implementation manner, after the network device sends the first indication message to the second terminal device, the network device synchronously obtains a second terminal device group to receive the MBS data, and the second terminal device group may indicate that there is more than one second terminal device capable of receiving the MBS data. In this case, each second terminal device in the second terminal device group has a second target MBS BWP identifier carried by the second indication information, and the network device compares the second target MBS BWP identifiers corresponding to each terminal device in the second terminal device group, and sends corresponding MBS data according to different comparison results. If the comparison result indicates that the second target MBS BWP identifications are the same identification, the network device sends the MBS data to the terminal devices of the second terminal device group according to the BWP indicated by the second target MBS sbwp identification, that is, sends the MBS data to multiple second terminal devices at the same time.
Further, if the comparison result indicates that the second target MBS BWP identifications are not the same identification, the network device sends MBS data to the corresponding terminal device on the BWP indicated by each second target MBS BWP identification according to the numerology used by the BWP corresponding to each second target MBS BWP identification.
In a possible implementation, for no terminal device interested in MBS data, in this case, the network device may also configure the second BWP set, just without sending MBS data to the terminal device on the corresponding BWP.
In this embodiment, a network device configures an MBS BWP set as a first BWP set, indicates a first target MBS BWP identifier in the first BWP set to a first terminal device, and sends a first indication message carrying the first target MBS BWP identifier to the first terminal device, where the first message is used to indicate the first terminal device to receive MBS data according to the BWP indicated by the first target MBS BWP identifier, further configures a second BWP set corresponding to a unicast partial carrier bandwidth BWP for a second terminal device interested in MBS data, determines a second target MBS BWP identifier according to the first BWP set and the second BWP set, and sends a second indication message carrying the second target MBS BWP identifier to the second terminal device, where the second indication message is used to indicate the second terminal device to receive MBS data according to the BWP indicated by the second target MBS BWP identifier. By the embodiment, the overlapping identifier (second target MBS BWP identifier) is utilized to support the transmission of the multicast service without performing corresponding conversion on the BWP, and meanwhile, the efficiency of receiving the multicast service by the terminal equipment is improved.
Referring to fig. 4, fig. 4 is another multicast service resource indication method disclosed in the application embodiment, where the method mainly uses a manner of interaction between a terminal device and a network device to perform related explanation, and specifically may include the following steps:
s401, the network device configures a first BWP set for the first terminal device and the second terminal device.
