These terms are only used to distinguish information of the same type from one another.

[0054] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.
[0055] In related technologies, MBMS (Multimedia Broadcast and Multicast Service) or MBS (Multicast Broadcast Service) is described as follows:
[0056] In 5G NR (New RAT (Radio Access Technology) systems, MBS services can be transmitted via the PDSCH (Physical Downlink Shared Channel) channel, which is scheduled by the PDCCH (Physical Downlink Control Channel). This PDCCH, which schedules MBS services, can be indicated by a scheduling identifier specific to MBS services (e.g., M-RNTI (MBS Radio Network Temporary Identity)).
[0057] MBS services can be identified by the following "MBS service identifier":
[0058] ① TMGI (Temporary Mobile Group Identity);
[0059] ② MBS Session ID;
[0060] ③ MBS QoS flow ID (MBS service flow identifier).
[0061] The transmission modes of MBS services can include the following two:
[0062] Transmission Mode 1: The UE needs to enter the connected state to receive the transmission configuration information of the MBS service in order to receive the MBS service;
[0063] Transmission Mode 2: The UE can receive the transmission configuration information of MBS service and receive MBS service in IDLE (idle mode) or INACTIVE (inactive mode) state.
[0064] In the aforementioned transmission mode 2, the network device (e.g., the base station) will send the transmission configuration information of the MBS service to the UE by combining system information and multicast control channel (e.g., MCCH (Multicast Control Channel)) information.
[0065] The system information mentioned above provides the MCCH transmission configuration information. For example, in a 4G LTE (Long Term Evolution) SC-PTM (Single Cell Point-to-Multipoint) system, network equipment (e.g., base stations) provides SC-MCCH (Single Cell–MCCH) channel configuration information in System Information Block 20 (SIB20), which may include:
[0066] ① The repetition period of the SC-MCCH channel (e.g., sc-mcch-RepetitionPeriod). Figure 1 20 wireless frames);
[0067] ② The system frame transmission time offset of the SC-MCCH channel (e.g., sc-mcch-Offset). Figure 1 , 1 radio frame), where SFN mod sc-mcch-RepetitionPeriod=sc-mcch-Offset, where, System Frame Number (SFN) is abbreviated as "SFN";
[0068] ③ The first subframe of the SC-MCCH channel (e.g., sc-mcch-FirstSubframe). Figure 1 (1st subframe)
[0069] ④ The duration of continuous scheduling of the SC-MCCH channel (e.g., sc-mcch-duration). Figure 1 (4 subframes), the continuous scheduling time starting from the subframe position indicated by sc-mcch-FirstSubframe;
[0070] ⑤ The change cycle of the SC-MCCH channel (e.g.) Figure 1 40 radio frames. The control signaling content transmitted through this SC-MCCH channel is the same during this change cycle.
[0071] When the information content of the multicast control channel changes, the network device (e.g., a base station) indicates the change in the information content of the multicast control channel in the first subframe of the repetition period of the multicast control channel (e.g., ...). Figure 1In subframe 1, the SC-MCCH channel information is indicated to have changed. When the UE receives this change indication, it can immediately re-receive the changed multicast control channel information (e.g., ...) from the subframe in which the change indication was received. Figure 1 After the UE receives the SC-MCCH channel information change indication in subframe 1, the UE receives the SC-MCCH channel information content in subframe 1.
[0072] The multicast control channel provides the transmission configuration information for the data channel of multicast services (e.g., MTCH (Multicast Traffic Channel)). For example, in a 4G LTE SC-PTM system, network equipment (e.g., base stations) provides the multicast traffic channel (SC-MTCH (Single Cell–MTCH)) configuration of its own cell and MBS service information of neighboring cells in the SC-MCCH control signaling, which may include:
[0073] ① The multicast service channel configuration InfoList for this cell (e.g., sc-mtch-InfoList);
[0074] ② NeighbourCellList of MBS services in neighboring cells (e.g., sc-ptm-NeighbourCellList).
[0075] Among them, ① "Multicast service channel configuration of this cell" may include:
[0076] 1. MBS session information (e.g., service identifier (e.g., TMGI-1) and session identifier (e.g., session-1));
[0077] 2. Scheduling identifier (e.g., the identifier G-RNTI-1 of the PDCCH used to schedule this MBS service);
[0078] 3. SC-MTCH scheduling information (e.g., sc-mtch-schedulingInfo, including: DRX (Discontinuous Reception) discontinuous scheduling time information for a specific MBS service (e.g., reception period and start offset (i.e., schedulingPeriodStartOffsetSCPTM); service reception duration within the period (i.e., onDurationTimerSCPTM))).
[0079] The following description, with reference to the accompanying drawings, details the beam determination method, apparatus, communication equipment, and computer storage medium provided in this disclosure.
[0080] Figure 2 This is a flowchart illustrating a beam determination method provided in an embodiment of the present disclosure, which can be applied to a terminal (i.e., user equipment), such as a mobile terminal like a mobile phone or tablet computer.
[0081] The beam determination method of this disclosure can also be executed by the beam determination device provided in this disclosure. The device can be configured in a communication device (e.g., a user equipment) to extract multicast control information from multicast control information transmission resources and determine the beam corresponding to the multicast control information according to the association between the multicast control information transmission resources and the beam, thereby effectively improving the reliability of the user equipment in receiving multicast control information under multiple beams.
[0082] like Figure 2 As shown, the method for determining the beam may include:
[0083] Step 201: Extract multicast control information from the multicast control information sending resources.
[0084] In this embodiment, multicast control information transmission resources can be transmitted by a base station. It should be noted that the base station described in this embodiment may include multiple cells providing services to user equipment. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with wireless user equipment (e.g., a mobile terminal) via one or more sectors on the air interface, or other names. The base station can be a network device.
[0085] In one embodiment of this disclosure, the multicast control information may include at least one of multicast control channel information and multicast control channel change indication.
[0086] In another embodiment of this disclosure, the multicast control information transmission resource may include one or more of the following: multicast control information scheduling control signaling transmission resource, multicast control information data transmission resource, and multicast control channel change indication transmission resource.
[0087] Specifically, the base station can transmit multicast control information transmission resources via a beam. After receiving the multicast control information transmission resources, the user equipment can parse them to obtain the multicast control channel information within the resources. It should be noted that the beam described in this embodiment can be a downlink beam signal.
[0088] In this embodiment of the disclosure, the base station can transmit multicast control information transmission resources through multiple beams. The multiple beams can be all the beams in the base station that can be used to transmit the multicast control information transmission resources, or at least one beam among all the beams that can be used to transmit the multicast control information transmission resources, determined by the base station according to a preset association relationship.
[0089] Step 202: Determine the beam corresponding to the multicast control information based on the association between multicast control information transmission resources and beams.
[0090] It should be noted that the association between the multicast control information transmission resources and the beam described in this embodiment can be pre-stored in the user equipment's storage space for easy retrieval and use. This storage space is not limited to physical storage space, such as a hard drive; it can also be the storage space of a server connected to the electronic device (e.g., a hospital server) (cloud storage space). The association between the multicast control information transmission resources and the beam described in this embodiment can be generated within the base station and pre-sent to the user terminal via Radio Resource Control (RRC) signaling, or it can be an association agreed upon by the base station and the user terminal (e.g., an agreement on beam number and multicast control information transmission resources), which can be automatically generated by the base station and the user terminal respectively, without any limitations here.
[0091] Specifically, after the user equipment extracts the multicast control channel information from the multicast control information transmission resources, it can retrieve the association relationship between the multicast control information transmission resources and the beam from its own storage space, and determine the beam corresponding to the multicast control information based on the association relationship.
[0092] In this embodiment, multicast control information is first extracted from multicast control information transmission resources, and the beam corresponding to the multicast control information is determined based on the association between the multicast control information transmission resources and the beam. This effectively improves the reliability of user equipment receiving multicast control information under multi-beam conditions.
[0093] To clearly illustrate the previous embodiment, in this embodiment of the disclosure, the base station can obtain multicast control information to be sent and obtain multicast control information transmission resources, and send the multicast control information transmission resources through multiple beams, wherein the multicast control information transmission resources carry multicast control information, and the multiple beams can be all beams in the base station that can be used to send the multicast control information transmission resources.
[0094] Specifically, the base station can provide "multicast control channel information transmission resources". (For example, multicast control information is sent to the UE through the MCCH channel in the logical channel, and the MCCH signaling is sent to the UE through the PDSCH of the PDCCH scheduling (e.g., the PDCCH identified by MC-RNTI). The base station provides listening resources for the PDCCH that transmits the MCCH signaling through the SIB15 (System Information Block 15) system information (e.g., CORESET (control resource set)-1 (i.e., frequency domain resources) and / or SearchSpace-1 (i.e., time domain resources (e.g., transmission period))).
[0095] The “multicast control channel information transmission resources” may include scheduling control signaling transmission resources (e.g., PDCCH transmission resources, used to schedule the transmission of MCCH signaling), that is, the aforementioned multicast control information scheduling control signaling transmission resources; and data transmission resources (e.g., PDSCH resources, used to transmit MCCH signaling), that is, the aforementioned multicast control information data transmission resources.
[0096] Furthermore, the base station can also provide "multicast control channel change indication transmission resources." (For example, the multicast control channel change indication is sent to the UE via the DCI (Downlink Control Information) in the PDCCH (e.g., the PDCCH identified by N-RNTI). The base station can provide listening resources (e.g., CORESET-2 and / or SearchSpace-2) for the PDCCH that transmits the "multicast control channel change indication" through SIB15 system information.)
[0097] Therefore, it can be seen that the base station can provide "multicast control information transmission resources", which may include one or more of the following: multicast control information scheduling control signaling transmission resources, multicast control information data transmission resources, and multicast control channel change indication transmission resources.
[0098] Then, the base station can obtain the multicast control information to be sent, put the multicast control information to be sent into the corresponding multicast control information transmission resource, and send the multicast control information transmission resource through multiple beams.
[0099] Furthermore, in this embodiment of the present disclosure, the base station can obtain multicast control information to be transmitted, obtain multicast control information transmission resources, determine the beam carrying the multicast control information transmission resources according to the association relationship between the multicast control information transmission resources and the beam, and then transmit the multicast control information transmission resources through the beam, wherein the multicast control information transmission resources carry multicast control information.
[0100] Specifically, the base station can provide "multicast control information transmission resources," acquire the multicast control information to be transmitted, and place the multicast control information to be transmitted into the corresponding multicast control information transmission resources. Then, the base station obtains the association relationship between the multicast control information transmission resources and the beam, and determines the beam carrying the multicast control information transmission resources based on this association relationship. This association relationship can be agreed upon through a protocol. For example, if the base station provides listening resources for the PDCCH used to transmit MCCH signaling (e.g., CORESET-1 and / or SearchSpace-1) through SIB15 system information, then for multiple PDCCH resources in the MCCH signaling transmission cycle, the protocol stipulates that the x-th PDCCH resource (or all PDCCH resources) can be used to transmit "multicast control information transmission resources," where x can be a positive integer, without any limitation. Finally, the multicast control information transmission resources are transmitted through the determined beam.
[0101] In one embodiment of this disclosure, such as Figure 3 As shown, the method for determining the beam may further include:
[0102] Step 301: Obtain the configuration information of the multicast control information transmission resources. The configuration information may be the configuration identifier of the Physical Downlink Control Channel (PDCCH), which may be the search space.
[0103] In this embodiment of the disclosure, the configuration information can be sent from the base station to the user equipment via Radio Resource Control (RRC) signaling. The base station can generate the configuration information based on the association between multicast control information transmission resources and beams, and the association can be directly specified by the base station. For example, the base station can specify the association between beam numbers and multicast control information transmission resources.
[0104] Specifically, the base station can directly designate certain beams for transmitting multicast control information resources as needed, and establish and save the association between the beam numbers of these beams and the multicast control information transmission resources for later retrieval. For example, the base station configures a PDCCH resource configuration SearchSpace-1 for MCCH signaling transmission, and for this SearchSpace-1, the base station designates its associated beam-1 (e.g., SSB-1). (For example, if the base station configures a PDCCH resource configuration SearchSpace-1 for MCCH signaling transmission, and this SearchSpace-1 configuration indicates that there are 2 PDCCH resources (i.e., PDCCH-1 and PDCCH-2) for every 10 slots, then the base station can indicate that PDCCH-1 corresponds to SSB-1, and PDCCH-2 corresponds to SSB-2.)
[0105] Simultaneously, the base station can generate configuration information based on this association and send this configuration information to the user equipment via Radio Resource Control (RRC) signaling. The user equipment receives the multicast control information sent by the base station, which contains the configuration information for the transmission resources.
[0106] Step 302: Determine the association between multicast control information transmission resources and beams based on the configuration information.
[0107] Specifically, after receiving the configuration information of the multicast control information transmission resources sent by the base station, the user equipment can parse the configuration information to determine the association between the multicast control information transmission resources and the beam. For example, the base station configures the PDCCH resource configuration SearchSpace-1 for the transmission of MCCH signaling, and for this SearchSpace-1, the base station specifies its associated beam-1 (e.g., SSB-1). (For example, if the base station configures the PDCCH resource configuration SearchSpace-1 for the transmission of MCCH signaling, and this SearchSpace-1 configuration indicates that there are 2 PDCCH resources (i.e., PDCCH-1 and PDCCH-2) for every 10 slots, then the base station can indicate that PDCCH-1 corresponds to SSB-1, and PDCCH-2 corresponds to SSB-2.)
[0108] In one embodiment of this disclosure, such as Figure 4 As shown, the method for determining the beam may further include:
[0109] Step 401: Obtain the group number of the multicast control information transmission resource.
[0110] In this embodiment of the disclosure, the group number can be a group number agreed upon in the protocol, wherein the protocol can stipulate that "multicast control information transmission resources with specific numbers" correspond to "beams with specific numbers". The "multicast control information transmission resources" are grouped according to the "number of beams corresponding to the transmission resources", and the group number corresponding to the "multicast control information transmission resource" corresponds to the specific beam number. The beam identification information may include at least one of the following: CSI-RS (Channel State Information-Reference Signal) identifier (e.g., CSI-RS-1), SSB identifier (e.g., SSB-1), etc.
[0111] Step 402: Determine the association between the multicast control information transmission resources and the beams based on the group numbers of the multicast control information transmission resources. The multicast control information transmission resources can be grouped in an interleaved manner according to time sequence or in consecutive groups. The total number of these groups can be determined by the total number of beams. For example, if the total number of beam numbers (e.g., SSB numbers) obtained by the user equipment from system information is 'a', then the total number of groups for the multicast control information transmission resources is also 'a', and the SSB numbers are the same as the group numbers of the multicast control information transmission resources. Here, 'a' can be a positive integer.
[0112] Specifically, after extracting the multicast control channel information from the multicast control information transmission resources, the user equipment can obtain the protocol-defined packet number (i.e., the packet number of the multicast control information transmission resources), and can interleave the "multicast control information transmission resources" according to the packet number in chronological order. For example, see [link to relevant documentation]. Figure 5 In one MCCH information transmission cycle, there are 8 PDCCH transmission resources (i.e., 1 / 2 / 3 / 4 and 6 / 7 / 8 / 9). The system information SIB-1 indicates that the cell has 4 beams (i.e., SSB-1 / 2 / 3 / 4). These 8 PDCCHs are divided into 4 beam groups, where PDCCH-1 / 6 can correspond to beam-1 (i.e., SSB-1), PDCCH-2 / 7 can correspond to beam-2 (i.e., SSB-2), PDCCH-3 / 8 can correspond to beam-3 (i.e., SSB-3), and PDCCH-4 / 9 can correspond to beam-4 (i.e., SSB-4).
[0113] Alternatively, the "Multicast Control Information Transmission Resources" can be grouped consecutively according to the group number, i.e., divided into the same group, for example, see [link to relevant documentation]. Figure 6 In one MCCH information transmission cycle, there are 8 PDCCH transmission resources (i.e., 1 / 2 / 3 / 4 and 6 / 7 / 8 / 9). The system information SIB-1 indicates that the cell has 2 beams (i.e., SSB-1 / 2). These 8 PDCCHs are then divided into 2 beam groups, where PDCCH-1 / 2 / 3 / 4 correspond to beam-1 (i.e., SSB-1), and PDCCH-6 / 7 / 8 / 9 correspond to beam-2 (i.e., SSB-2).
[0114] Therefore, the user equipment can determine the association between the multicast control information transmission resources and the beam based on the aforementioned group number, and determine the beam corresponding to the multicast control information based on the association, wherein the beam can be at least one.
[0115] Furthermore, in one embodiment of this disclosure, after determining the beam corresponding to the multicast control information based on the association between the multicast control information transmission resource and the beam, the method may further include, if there are multiple determined beams, determining a target beam from among the multiple determined beams, and monitoring the multicast control information transmission resource corresponding to the target beam to obtain the multicast control information transmitted by the target beam.
[0116] It should be noted that the defined beams described in this embodiment are multiple, which means that these multiple beams can all be used to carry multicast control information transmission resources, and the user terminal can obtain multicast control information transmission resources from any one of these multiple beams.
[0117] Specifically, after determining the multiple beams corresponding to the multicast control information, the user equipment can select at least one beam from these beams and monitor its content. The user equipment can select at least one beam (i.e., the target beam) from the multiple beams according to a preset selection strategy, which can be calibrated according to actual conditions. Then, the user equipment monitors the multicast control information transmission resources corresponding to the at least one beam to obtain the multicast control information transmitted by that at least one beam.
[0118] Furthermore, assuming that the multicast control information received by the user equipment is a multicast control channel change indication, after receiving the multicast control channel change indication, the user equipment can control the multicast control channel to change according to the multicast control channel change indication. When making the change, the user equipment can determine the beam associated with the multicast control channel change indication and receive the multicast control channel information through the "multicast control channel information transmission resource" associated with the beam.
[0119] To clearly illustrate the previous embodiment, in one embodiment of this disclosure, determining a target beam from a plurality of defined beams may include acquiring the signal quality of the plurality of beams and selecting the target beam based on the signal quality.
[0120] Specifically, after determining the multiple beams corresponding to the multicast control information, the user equipment can detect the signal quality of each of the multiple beams, take the beam with the best signal quality as the target beam, and listen to the multicast control information transmission resources corresponding to the target beam to obtain the multicast control channel change indication sent by the target beam.
[0121] To clearly illustrate the previous embodiment, in another embodiment of this disclosure, determining the target beam from a plurality of defined beams may include acquiring the signal quality of the plurality of beams, selecting beams with signal quality greater than a quality threshold as candidate beams, and selecting the target beam from the plurality of candidate beams. The quality threshold can be calibrated according to actual conditions; for example, the quality threshold may be a quality threshold agreed upon in a protocol, or a quality threshold specified in the aforementioned configuration information.
[0122] Specifically, after determining the multiple beams corresponding to the multicast control information, the user equipment can detect the signal quality of each of the multiple beams, and select the beams whose signal quality is greater than the quality threshold as candidate beams. Then, it can randomly select at least one beam from the candidate beams as the target beam and listen to the content carried by it.
[0123] For example, see Figure 5 If the user equipment detects that the signal quality of SSB-1 is good (e.g., the RSRP (Reference Signal Received Power) measurement result of SSB-1 is greater than or equal to the quality threshold), then the user equipment may only listen to PDCCH-1 / 6. See also Figure 6 If the user equipment detects that the signal quality of SSB-1 is good, the user equipment can listen to PDCCH-1 / 2 / 3 / 4 only.
[0124] Furthermore, in one embodiment of this disclosure, the above-described beam determination method may further include acquiring spatial information of the beam, wherein the spatial information is used for receiving multicast control information, and the spatial information may include at least one of Doppler translation information, Doppler propagation information, average delay information, delay spread information, and spatial receiver parameter information.
[0125] It should be noted that the spatial information described in this embodiment may be the spatial information of the signal on the beam, and the beam may be the target beam mentioned above.
[0126] Specifically, the user equipment can acquire the spatial information of the signal on the received beam (e.g., the target beam) and use this spatial information for the physical channel associated with that beam for transmitting "multicast control information". For example, if the PDCCH resource-1 corresponding to the MCCH information reception is associated with SSB-1, then the spatial information of SSB-1 can be used for receiving the PDCCH channel of that PDCCH resource-1. As another example, if the PDCCH resource-1 corresponding to the MCCH information reception is associated with SSB-1, then the spatial information of SSB-1 can be used for receiving the PDSCH channel scheduled by that PDCCH resource-1.
[0127] Furthermore, in embodiments of this disclosure, when the "multicast control channel change indication transmission resource" is included in the "multicast control channel information transmission resource," the "multicast control channel change indication transmission resource" can be allocated according to the following allocation method:
[0128] When the aforementioned association is a relationship agreed upon by the base station and user terminal protocol, and the "multicast control channel information transmission resources" are grouped in an interleaved manner according to time sequence, the "multicast control channel change indication transmission resources" can be the "multicast control channel information transmission resources" corresponding to y consecutive beams in the xth group. For example, see Figure 5 In one MCCH information transmission cycle, there are 8 PDCCH transmission resources (i.e., 1 / 2 / 3 / 4 and 6 / 7 / 8 / 9). The system information SIB-1 indicates that the cell has 4 beams (i.e., SSB-1 / 2 / 3 / 4). These 8 PDCCHs can be divided into 4 beam groups, where PDCCH-1 / 6 corresponds to beam-1 (i.e., SSB-1), PDCCH-2 / 7 corresponds to beam-2 (i.e., SSB-2), PDCCH-3 / 8 corresponds to beam-3 (i.e., SSB-3), and PDCCH-4 / 9 corresponds to beam-4 (i.e., SSB-4). PDCCH-1 / 2 / 3 / 4 correspond to consecutive beams-1 / 2 / 3 / 4, so they are numbered as group 1. PDCCH-6 / 7 / 8 / 9 correspond to consecutive beams-1 / 2 / 3 / 4, so they are numbered as group 2. Then the PDCCH-1 / 2 / 3 / 4 of the first group is "Multicast Control Channel Change Indicator Transmission Resource".
[0129] When the aforementioned association is the association agreed upon by the base station and user terminal protocol, and the "multicast control information transmission resources" are continuously grouped (divided into the same group), the "multicast control channel change indication transmission resource" is the x-th resource in the resources corresponding to each beam. For example, see... Figure 6 In one MCCH information transmission cycle, there are 8 PDCCH transmission resources (i.e., 1 / 2 / 3 / 4 and 6 / 7 / 8 / 9). System information SIB-1 indicates that the cell has 2 beams (i.e., SSB-1 / 2). These 8 PDCCHs can be divided into 2 beam groups, where PDCCH-1 / 2 / 3 / 4 correspond to beam-1 (i.e., SSB-1), and PDCCH-6 / 7 / 8 / 9 correspond to beam-2 (i.e., SSB-2). The first resource of beam-1 and beam-2 (i.e., PDCCH-1 / 6) is the "Multicast Control Channel Change Indication Transmission Resource".
[0130] According to the beam determination method of this disclosure, multicast control information is extracted from multicast control information transmission resources, and the beam corresponding to the multicast control information is determined based on the association between the multicast control information transmission resources and the beam. This ensures that user equipment can receive multicast control information under different beams, thereby effectively improving the reliability of user equipment receiving multicast control information under multiple beams.
[0131] Figure 7 This is a flowchart illustrating another beam determination method provided in this embodiment, applicable to the network side, such as a base station. It should be noted that the base station described in this embodiment may include multiple cells providing services to user equipment. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with wireless user equipment (e.g., a mobile terminal) via one or more sectors on the air interface, or other names. The base station can be a network device.
[0132] The beam determination method of this disclosure can also be executed by the beam determination device provided in this disclosure. The device can be configured in a communication device (e.g., a base station) to acquire multicast control information to be transmitted, acquire multicast control information transmission resources, determine the beam carrying the multicast control information transmission resources according to the association between the multicast control information transmission resources and the beam, and then transmit the multicast control information transmission resources through the beam, thereby effectively improving the reliability of user equipment receiving multicast control information under multiple beams.
[0133] like Figure 7 As shown, the method for determining the beam may include:
[0134] Step 701: Obtain the multicast control information to be sent. The multicast control information may include at least one of multicast control channel information and multicast control channel change indication.
[0135] Step 702: Obtain multicast control information transmission resources, and determine the beam carrying the multicast control information transmission resources based on the association between the multicast control information transmission resources and the beam. The multicast control information transmission resources may include one or more of the following: multicast control information scheduling control signaling transmission resources, multicast control information data transmission resources, and multicast control channel change indication transmission resources.
[0136] Step 703: Send multicast control information transmission resources via beam, wherein the multicast control information transmission resources carry multicast control information.
[0137] Specifically, the base station can provide "multicast control channel information transmission resources". (For example, multicast control information is sent to the UE through the MCCH channel in the logical channel, and the MCCH signaling is sent to the UE through the PDSCH of the PDCCH scheduling (e.g., the PDCCH identified by MC-RNTI). The base station provides listening resources for the PDCCH that transmits the MCCH signaling through the SIB15 (System Information Block 15) system information (e.g., CORESET (control resource set)-1 (i.e., frequency domain resources) and / or SearchSpace-1 (i.e., time domain resources (e.g., transmission period))).
[0138] The “multicast control channel information transmission resources” may include scheduling control signaling transmission resources (e.g., PDCCH transmission resources, used to schedule the transmission of MCCH signaling), that is, the aforementioned multicast control information scheduling control signaling transmission resources; and data transmission resources (e.g., PDSCH resources, used to transmit MCCH signaling), that is, the aforementioned multicast control information data transmission resources.
[0139] Furthermore, the base station can also provide "multicast control channel change indication transmission resources." (For example, the multicast control channel change indication is sent to the UE via the DCI (Downlink Control Information) in the PDCCH (e.g., the PDCCH identified by N-RNTI). The base station can provide listening resources (e.g., CORESET-2 and / or SearchSpace-2) for the PDCCH that transmits the "multicast control channel change indication" through SIB15 system information.)
[0140] Therefore, it can be seen that the base station can provide "multicast control information transmission resources", which may include one or more of the following: multicast control information scheduling control signaling transmission resources, multicast control information data transmission resources, and multicast control channel change indication transmission resources.
[0141] Then, the base station can obtain the multicast control information to be sent and place it into the corresponding multicast control information transmission resource. The base station can then obtain the association between the multicast control information transmission resource and the beam, and determine the beam carrying the multicast control information transmission resource based on this association. This association can be agreed upon through a protocol. For example, if the base station provides listening resources for the PDCCH used to send MCCH signaling (e.g., CORESET-1 and / or SearchSpace-1) through SIB15 system information, then for multiple PDCCH resources in the MCCH signaling transmission cycle, the protocol stipulates that the x-th PDCCH resource (or all PDCCH resources) can be used to send the "multicast control information transmission resource," where x can be a positive integer, without any limitation. Finally, the multicast control information transmission resource is sent through the determined beam.
[0142] The base station can also directly specify the association between the multicast control information transmission resources and the beam.
[0143] In this embodiment, multicast control information to be transmitted is first acquired, and multicast control information transmission resources are acquired. The beam carrying the multicast control information transmission resources is determined based on the association between the multicast control information transmission resources and the beam. Then, the multicast control information transmission resources are transmitted through the beam. This effectively improves the reliability of user equipment receiving multicast control information under multi-beam conditions.
[0144] Furthermore, in one disclosed embodiment, the above-mentioned beam determination method further includes generating configuration information based on the association between multicast control information transmission resources and beams, and transmitting the configuration information through radio resource control (RRC) signaling.
[0145] Specifically, the base station can directly designate certain beams for transmitting multicast control information resources as needed, and establish and save the association between the beam numbers of these beams and the multicast control information transmission resources for later retrieval. For example, the base station configures a PDCCH resource configuration SearchSpace-1 for MCCH signaling transmission, and for this SearchSpace-1, the base station designates its associated beam-1 (e.g., SSB-1). (For example, if the base station configures a PDCCH resource configuration SearchSpace-1 for MCCH signaling transmission, and this SearchSpace-1 configuration indicates that there are 2 PDCCH resources (i.e., PDCCH-1 and PDCCH-2) for every 10 slots, then the base station can indicate that PDCCH-1 corresponds to SSB-1, and PDCCH-2 corresponds to SSB-2.)
[0146] Simultaneously, the base station can generate configuration information based on this association and send this configuration information to the user equipment via Radio Resource Control (RRC) signaling. The user equipment receives the multicast control information sent by the base station, which contains the configuration information for the transmission resources.
[0147] Optionally, the multicast control information transmission resources include one or more of the following: multicast control information scheduling control signaling transmission resources, multicast control information data transmission resources, and multicast control channel change indication transmission resources.
[0148] It should be noted that the above refers to... Figures 2 to 6 The explanation of the provided beam determination method embodiment also applies to the beam determination method of this embodiment, and will not be repeated here.
[0149] According to the beam determination method of this disclosure, firstly, multicast control information to be transmitted is acquired, and multicast control information transmission resources are acquired. Then, the beam carrying the multicast control information transmission resources is determined based on the association between the multicast control information transmission resources and the beam. Finally, the multicast control information transmission resources are transmitted through the beam. This ensures that the user equipment can receive multicast control information under different beams, thereby effectively improving the reliability of the user equipment receiving multicast control information under multiple beams.
