Description

Technical Field

[0001] (Cross - reference to related applications) This application is filed based on the Chinese patent application with application number 202010785850.2 and filing date August 6, 2020, and claims the priority of the Chinese patent application. All the contents of the Chinese patent application are hereby incorporated herein by reference. This application relates to the technical field of wireless communication, and particularly relates to information communication methods, information receiving methods, information setting methods, information sending methods, resource setting methods, and devices.

Background Art

[0002] As a requirement of related technologies, it is to specify the basic functions of the Radio Access Network (RAN) for broadcast / multicast to terminals in the connected state (RRC CONNECTED).

[0003] As shown in FIG. 1, in the conventional technology, the modification means of the Single Cell - Multicast Control Channel (SC - MCCH) is that the entire MCCH information is periodically transmitted based on the "repetition period". The "Modification period" is defined as an integer multiple of the "repetition period". After the terminal (UE) receives the MCCH update indication (Change notification) in the nth modification period, it waits for the next modification period to read the change of the MCCH information. The method of realizing the update of the SC - MCCH information by notifying the period and the modification period (tens of milliseconds) through such upper - layer RRC signaling consumes a long time and the terminal is slow to obtain the MCCH modification information.

[0177] To further clarify the objectives, technical means, and advantages of the embodiments of this disclosure, the technical means of the embodiments of this disclosure will be clearly and completely described below with reference to the drawings of the embodiments. Clearly, the embodiments described are some, but not all, embodiments of this disclosure. Any other embodiments obtained by a person skilled in the art based on the embodiments of this disclosure described are within the scope of protection of this disclosure.

[0178] As shown in Figure 2, Figure 2 is a flowchart of an information communication method provided by an embodiment of the present disclosure, the method being applied to network-side equipment and including step 21.

[0179] Step 21: Send first Downlink Control Information (DCI) scrambled with a first Radio Network Temporary Identifier (RNTI) to the terminal, and the first DCI is used to indicate whether the control information for one multicast service and / or broadcast service has been updated, or to indicate update-related information. The aforementioned control information includes configuration information for multicast services and / or broadcast services.

[0180] The embodiments of this disclosure utilize DCI to indicate whether the control information for multicast and / or broadcast services has been updated, thereby accelerating the acquisition of multicast control channel (MCCH) correction information by terminals, enabling faster acquisition of accurate multicast and / or broadcast data, meeting low latency requirements, and being applicable to 5G multi-application scenarios.

[0181] Selectively, the configuration information for one multicast service and / or broadcast service is: List of Temporary Mobile Group Identity (TMGI) The session identifier (Session ID) corresponding to the TMGI in the TMGI list, The group corresponding to TMGI in the TMGI list is RNTI (G-RNTI), The bandwidth part (BWP) corresponding to the TMGI in the TMGI list, Subcarrier interval corresponding to TMGI in the TMGI list, Logical channels and / or logical channel groups corresponding to TMGI in the TMGI list, Discontinuous Reception (DRX) settings corresponding to TMGI in the TMGI list. Upstream resource settings for Hybrid Automatic Repeat request (HARQ) feedback corresponding to TMGI in the TMGI list, and, The list of TMGIs includes at least one upstream resource setting for reporting Channel State Information (CSI) corresponding to the TMGI.

[0182] Naturally, the configuration information for multicast and / or broadcast services on the MCCH may further include, in addition to at least one of the above, at least one of the following: a synchronization signal / physical broadcast channel signal block (or synchronization signal block, SSB, i.e., an SS / PBCH Block which may include a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcast channel), a Channel State Information Reference Signal (CSI-RS), a Transmission Configuration Indicator (TCI), and beams.

[0183] PBCH stands for Physical Broadcast Channel. SSB stands for Synchronization Signal and PBCH block (abbreviated as SSB).

[0184] Selectively, the aforementioned first DCI is, Changes in the control information for multicast and / or broadcast services, Whether or not the control information for multicast services and / or broadcast services has changed. Changed control information for the multicast service and / or broadcast service, The type of control information for the multicast service and / or broadcast service that has changed, and It is used to instruct at least one of the following: to read resource information of the control information of the changed multicast service and / or broadcast service.

[0185] If the first DCI is selectively used to indicate that control information for multicast and / or broadcast services has changed, the first DCI may further... The configuration information for the multicast service and / or broadcast service has changed. The transmission method for the multicast service and / or broadcast service has been changed from a single-cell single-point-to-multipoint (SC-PTM) transmission method to a multi-cell single-point-to-multipoint (i.e., MBMS) transmission method. The transmission method for the multicast service and / or broadcast service has been changed from a multi-cell single-point-to-multipoint transmission method to a single-cell single-point-to-multipoint transmission method. The transmission method for the multicast service and / or broadcast service has been changed from a single-point to multipoint transmission method to a single-point to single-point transmission method. The transmission method for the multicast service and / or broadcast service has been changed from a single-point to single-point transmission method to a single-point to multi-point transmission method. The multicast or broadcast service whose control information for the multicast service and / or broadcast service has changed, We have added a new group of multicast and / or broadcast services. The group of existing multicast and / or broadcast services has been deleted. We have updated our existing multicast and / or broadcast service group. The fact that HARQ feedback for the multicast service and / or broadcast service has been turned off or on, This is used to indicate that CSI feedback for the multicast service and / or broadcast service has been turned on or off, or at least one of these.

[0186] In the embodiments of this disclosure, one scheduling unit (e.g., one time slot) can specify one or more of the above information.

[0187] For example, if a single cell has one Single Cell Multicast Control Channel (SC-MCCH), updating the SC-MCCH information can be achieved with a single PDCCH, eliminating the need for the conventional method of updating SC-MCCH information by notifying the period and correction period. The specific method is as follows.

[0188] The MCCH state can be indicated using one of the DCI fields of the PDCCH, and the message can be scrambled with a new RNTI, or it can be scrambled using SC-RNTI.

[0189] The MCCH state indicator-2 bits are determined based on Table 1 below.

[0190] [Table 1]

[0191] Alternatively, the MCCH state indicator-4 bits are determined based on Table 2 below.

[0192] [Table 2]

[0193] If it is 11 in Table 1 or 1111 in Table 2, it is Messages-8. If it is 01 or 0001, this field is reserved and the UE can ignore Tables 3 and 4 below.

[0194] [Table 3]

[0195] or [Table 4]

[0196] Next, the UE determines, based on the contents of this DCI, whether the SC-MCCH information has been changed, and selectively determines, specifically, which multicast service's SC-MCCH information has been changed, and / or the specific changes, and where the changed SC-MCCH information can be read.

[0197] Finally, the UE reads the SC-PTM configuration information based on the modified SC-MCCH information.

[0198] Also, for example, if one cell has multiple SC-MCCHs, Step 1: Different SC-RNTIs belong to different groups, and the correspondence between different multicast services and SC-RNTIs is established using RRC messages. Step two: Updating SC-MCCH information can be achieved with a single PDCCH, eliminating the need for the conventional method of updating SC-MCCH information by notifying the period and correction period. The specific method is as follows:

[0199] The MCCH state can be indicated using one of the DCI fields of the PDCCH, and the message can be scrambled with a new RNTI, or it can be scrambled using SC-RNTI. The MCCH state indicator-2 bits are determined based on the following table. [Table 4A] If it's 11, it's Messages-8 bits. If it's 01, this field is reserved, and the UE can ignore Table 5 below.

[0200] [Table 5]

[0201] Next, the UE determines, based on the contents of this DCI, whether the SC-MCCH information has been changed, and selectively determines, specifically, which multicast service's SC-MCCH information has been changed, and / or the specific changes, and where the changed SC-MCCH information can be read.

[0202] Selectively, the first DCI is, The configuration information for the multicast service and / or broadcast service has changed. The transmission method for the multicast service and / or broadcast service has been changed from a single-cell single-point-to-multipoint transmission method to a multi-cell single-point-to-multipoint transmission method. The transmission method for the multicast service and / or broadcast service has been changed from a multi-cell single-point-to-multipoint transmission method to a single-cell single-point-to-multipoint transmission method. The transmission method for the multicast service and / or broadcast service has been changed from a single-point to multipoint transmission method to a single-point to single-point transmission method. The transmission method for the multicast service and / or broadcast service has been changed from a single-point to single-point transmission method to a single-point to multi-point transmission method. The multicast or broadcast service whose control information for the multicast service and / or broadcast service has changed, We have added a new group of multicast and / or broadcast services. The group of existing multicast and / or broadcast services has been deleted. We have updated our existing multicast and / or broadcast service group. The fact that HARQ feedback for the multicast service and / or broadcast service has been turned off or on, This is used to indicate that CSI feedback for the multicast service and / or broadcast service has been turned on or off, or at least one of these.

[0203] Selectively, after sending the first DCI scrambled with the first RNTI to the terminal, The first DCI may include information to indicate that control information for multicast services and / or broadcast services has changed, and / or If the control information for multicast services and / or broadcast services includes a resource for change information, it includes transmitting change information for the control information of the multicast services and / or broadcast services.

[0204] Selectively, the method further, A step of broadcasting the control information of each multicast service and / or broadcast service from among the control information of multiple multicast services and / or broadcast services, or A step of broadcasting control information for a first multicast service and / or broadcast service among control information for multiple multicast services and / or broadcast services, wherein the control information for the other multicast services and / or broadcast services among the multiple multicast services and / or broadcast services is the same as the control information for the first multicast service and / or broadcast service, The control information includes at least one of the following: repetition period, offset amount, start subframe, and correction period.

[0205] In embodiments of this disclosure, if there are multiple SC-MCCHs in a cell, for example, if there are 10 SC-MCCHs, one method is to still broadcast scheduling information such as the repetition period, offset amount, start subframe and correction period of each set of SC-MCCHs via system messages, or When scheduling information parameters such as the information transmission repetition period, offset amount, start subframe, and correction period are the same across multiple multicast groups, one set is broadcast first, and then multicast group information is added. Alternatively, if the repetition cycles of transmission information from different groups are the same, in order to maintain good forward compatibility and save signaling overhead, it is not necessary to broadcast the repetition cycles, offset amounts, start subframes, and correction cycles of multiple sets of SC-MCCH in a system message. Instead, scheduling information such as the repetition cycle, offset amount, start subframe, and correction cycle of only one set of SC-MCCH is still broadcast in the system message, and the UE derives the occurrence time of the corresponding group's SC-MCCH based on the ID numbers of the different groups.

[0206] As shown in Figure 3, Figure 3 is a flowchart of an information communication method provided by an embodiment of the present disclosure, the method being applied to network-side equipment and including step 31.

[0207] Step 31: A second DCI, scrambled with a second RNTI, is sent to the terminal, and the second DCI is used to indicate whether the control information for one multicast service and / or broadcast service set has been updated, or to indicate update-related information. The aforementioned control information includes configuration information for multicast services and / or broadcast services.

[0208] The embodiments of this disclosure utilize DCI to indicate whether the control information for multicast and / or broadcast services has been updated, thereby accelerating the acquisition of multicast control channel (MCCH) correction information by terminals, enabling faster acquisition of accurate multicast and / or broadcast data, meeting low latency requirements, and being applicable to 5G multi-application scenarios.

[0244] As shown in Figure 7, Figure 7 is a flowchart of an information receiving method provided by an embodiment of the present disclosure, the method being applied to a terminal and including the following step 71.

[0245] Step 71: Determine the monitoring occasions for one or more multicast messages on the physical downlink control channel PDCCH, and receive multicast information on the monitoring occasions for the multicast messages on the physical downlink control channel PDCCH. The occasion for one multicast message is the monitoring occasion for one group of multicast messages in the PDCCH. A PDCCH monitoring occasion for a single multicast message includes at least one time slot. Each time slot included in the monitoring occasion of a PDCCH for a single multicast message contains at least one time symbol. Multicast information, DCI for scheduling multicast services via the network. DCI, for scheduling multicast service configuration information over the network. DCI information for the control channel of multicast services. DCI, for scheduling information on the control channel of multicast services via the network. DCI scheduling information for multicast service control channel information. DCI, for scheduling correction information for the control channel of multicast services via the network. DCI of correction information for the control channel of multicast services, and The DCI includes at least one of the following: correction information for the control channel of a multicast service, scheduling information, and DCI.

[0246] Multicast messages are content attached to PDSCH, multicast information refers to monitored content, and terminals can use multicast information to find the resources that send multicast messages.

[0247] In the embodiments of this disclosure, the term "receive" in "determine the monitoring occasions for one or more multicast messages on the physical downlink control channel PDCCH and receive multicast information on the monitoring occasions for the multicast messages on the physical downlink control channel PDCCH" also means "monitor" or "discover."

[0248] In the embodiments of this disclosure, for monitoring occasions (MOs) that monitor multicast scheduling information and / or multicast service information, particularly for idle and connected terminals, multicast scheduling information and / or multicast service information can be received using a common search space. The terminals can then wake up in the corresponding scheduling time slot and monitor the PDCCH and the corresponding PDSCH, eliminating the need to continuously monitor the SC-RNTI's PDCCH and thereby reducing power consumption.

[0249] Taking the monitoring of multicast scheduling information as an example, a terminal monitors multicast scheduling information within a multicast scheduling information occasion (MO) during each period in which it reads multicast scheduling information. An MO is a group of PDCCH monitoring occasions and can contain multiple time slots (e.g., subframes or orthogonal frequency division multiplexing (OFDM) symbols) within which it can transmit the DCI of a multicast scheduling message.

[0250] Selectively determining the monitoring occasions for the physical downlink control channel PDCCH of one or more multicast messages is: Determining the monitoring occasion for the PDCCH of multicast messages based on the multicast message search space or set of multicast message search spaces, The search space for multicast messages, A method by which a UE reads information about a set of Nth-class PDCCH common search spaces for multicast message search space configuration from a PDCCH common configuration set by an RRC message, wherein the common search space is used in a DCI format that is scrambled with cyclic redundancy check (CRC) by multicast-RNTI in the primary cell. A method by which a UE reads a search space of a common identifier type from a PDCCH-specific configuration set by an RRC message, wherein the search space is used for a DCI format in which CRC scrambling is performed by multicast-RNTI in the primary cell. If the UE does not discover the setting of information for a Type N PDCCH common search space set for multicast message search space configuration using RRC messages, the association between PDCCH monitoring occasions and SSB block indices for a Type N PDCCH common search space set is the same as the association between PDCCH monitoring occasions and Type 0 PDCCH common search spaces, and This includes determining by at least one method of finding the CCE aggregation level and the number of PDCCH candidates for each CCE aggregation level in the common search space set of PDCCHs of class N, using a table lookup. Information on the common search space set of PDCCH of Class N, and / or information on search spaces identified as common types, Search space number, The first instruction information used to indicate the first time symbol in the control resource set within a single slot used for monitoring the PDCCH of a multicast message. Second instruction information used to specify the monitoring period and time offset amount used for monitoring the PDCCH monitoring occasion of multicast messages, Third directive information used to indicate the start symbol and / or duration in one monitoring cycle used for monitoring occasions of the PDCCH of multicast messages, A fourth directive information in bitmap format that indicates the monitoring time slot and / or monitoring time symbol used for monitoring occasions of the PDCCH of multicast messages, A fifth directive in bitmap format that indicates the monitoring time symbol in one time slot used for monitoring occasions of the PDCCH of multicast messages, A sixth instruction information used to indicate the start symbol and / or duration of one time slot used for monitoring occasions of the PDCCH of multicast messages, and This includes at least one of seven directive pieces of information used to indicate an index of the control resource set associated with this search space.

[0251] Selectively, the monitoring occasions of one or more multicast messages in the PDCCH constitute an occasion for a single multicast message.

[0252] The following explains, with examples, how to determine the MF and MO for monitoring multicast scheduling messages.

[0253] Based on the PDCCH Search Space set, a set of PDCCH candidates for monitoring by the terminal is defined, and the search space set may be a common search space set or a search space set specific to the terminal. The terminal uses a TypeN-PDCCH common search space set which adds the X-SearchSpace setting to PDCCH-ConfigCommon (PDCCH common settings), and is used for configuring the DCI format in which the CRC is scrambled by multicast-RNTI in the primary cell. If the UE is not provided with the higher-level parameter MB-SearchSpace for the type x-PDCCH common search space set, the association between the PDCCH monitoring occasions and the SS / PBCH block index for the type X-PDCCH common search space set is the same as the association for the TYPE 0-PDCCH common monitoring occasions, and the X-PDCCH common search space set allows the Control Channel Element (CCE) aggregation level and the number of PDCCH candidates for each CCE aggregation level in the X-PDCCH common search space set to be found by table lookup. Based on the X-Search Space defined by the protocol and the monitoring occasions of the first PDCCH configured by RRC signaling, the monitoring occasions of the PDCCH for monitoring multicast scheduling information are determined, and / or the network determines whether the monitoring occasions of the PDCCH for multicast scheduling are the same as the RMSI, and PDCCH candidates are monitored in one or more search space sets of the X-PDCCH Common Search Space Set.

[0254] For each monitoring time slot and / or monitoring time symbol that indicates PDCCH monitoring occasions for multicast messages in bitmap format, for example, if there are two Monitoring-periodicity-PDCCH-slots, then each slot has eight PDCCH monitoring occasions (MO). Specifically, the RRC can define the start OFDM time symbol and which specific symbols need to be monitored. For example, if it is 001111011100000111101111000, then symbols #2, 3, 4, 5, #7, 8, 9, and 10 need to be monitored. Or, If there are two Monitoring-periodicity-PDCCH-slots, then within each slot there are four PDCCH monitoring occasions. The symbols to be monitored in the first slot are #2, 3, 4, and 5, and the symbols to be monitored in the second slot are #7, 8, 9, and 10. Specifically, the RRC can define the start OFDM time symbol and which specific symbols (e.g., 00111100000000000001111000) need to be monitored.

[0255] Selectively, the method further, The process includes the step of determining a multicast scheduling radio frame (MF), which is a system frame containing one or more MOs or MO origins.

[0256] A multicast scheduling radio frame (MF) is a system frame that may contain one or more MOs or MO origins.

[0257] Selectively, the above method, The process includes the step of selecting one or more beams for receiving multicast scheduling information.

[0258] The SSB / CSI-RS is relevant to beam information.

[0259] In multibeam operation, the UE can assume that the same multicast scheduling message is repeated on all transmitted beams, and therefore the UE can select one or more beams to receive the multicast scheduling message.

[0260] Selectively, one multicast message occasion is a monitoring occasion for Y multicast messages in the PDCCH, where Y is determined based on the number of SSBs actually sent from the cell.

[0261] MO is for a group of Y consecutive PDCCH monitors, where Y is determined based on the number of SSBs actually transmitted by the cell.

[0262] Selectively, one multicast message occasion is a PDCCH monitoring occasion for one group of multicast messages. The monitoring occasion for the Zth PDCCH in a multicast message corresponds to the Zth SSB being sent, where Z is a positive integer.

[0263] The meaning of the Zth PDCCH monitoring occasion is that one multicast message occasion consists of Y multicast message PDCCH monitoring occasions, and therefore the Zth PDCCH monitoring occasion is the Zth PDCCH monitoring occasion within these Y multicast message PDCCH monitoring occasions.

[0264] As shown in Figure 7a, Figure 7a is a flowchart of an information transmission method provided by an embodiment of the present disclosure, which is applied to network-side equipment and includes the following step 701.

[0265] Step 701: Send multicast information on the monitoring occasion of one or more multicast messages on the physical downlink control channel PDCCH.

[0267] The step of selectively transmitting multicast information on the monitoring occasion of the physical downlink control channel PDCCH for one or more multicast messages is: Associating the monitoring occasion of the multicast message's PDCCH with the corresponding multicast message's search space or multicast message's search space set, The search space for multicast messages, A method for configuring the PDCCH common settings set by the Radio Resource Control RRC message, using information for the Nth class PDCCH common search space set for multicast message search space configuration, wherein this common search space is used in the DCI format where the cyclic redundancy check code CRC is scrambled by multicast-RNTI in the primary cell, and A method of configuring a PDCCH-specific configuration set by an RRC message, wherein the identifier is a common type search space, and the search space is used for the DCI format in which CRCs are scrambled by multicast-RNTI in the primary cell, comprising at least one of these methods, Information on the common search space set of PDCCH of Class N, and / or information on search spaces identified as common types, Search space number, First instruction information used to indicate the first time symbol in the control resource set within one slot used for monitoring occasions of the PDCCH of multicast messages, Second instruction information used to specify the monitoring period and time offset amount used for monitoring the PDCCH monitoring occasion of multicast messages, Third directive information used to indicate the start symbol and / or duration in one monitoring cycle used for monitoring occasions of the PDCCH of multicast messages, A fourth directive information in bitmap format that indicates the monitoring time slot and / or monitoring time symbol used for monitoring occasions of the PDCCH of multicast messages.

[0272] Selectively, one multicast message occasion is a PDCCH monitoring occasion for one group of multicast messages. The monitoring occasion for the Zth PDCCH in a multicast message corresponds to the Zth SSB being sent, where Z is a positive integer.

[0273] As shown in Figure 7b, Figure 7b is a flowchart of an information receiving method provided by an embodiment of the present disclosure, the method being applied to a terminal and including the following steps 711.

[0274] Step 711: Determine the monitoring occasion for one or more multicast messages on the PDCCH, and receive multicast information on the multicast message occasion.

[0275] In the embodiments of this disclosure, the term "receive" in "determine the monitoring occasions for one or more multicast messages on the physical downlink control channel PDCCH and receive multicast information on the monitoring occasions for the multicast messages on the physical downlink control channel PDCCH" also means "monitor" or "discover."

[0276] In the embodiments of this disclosure, regarding the monitoring occasions of the PDCCH that monitor multicast scheduling information and / or multicast service information, particularly for idle and connected terminals, multicast scheduling information and / or multicast service information can be received using a common search space. The terminals only need to wake up in the corresponding scheduling time slot to monitor the PDCCH and the corresponding PDSCH, eliminating the need to continuously monitor the multicast RNTI's PDCCH and reducing power consumption.

[0277] The monitoring occasion for multicast messages in the PDCCH is determined based on the multicast message search space or the set of multicast message search spaces.

If the UE does not discover the setting of information for a Type N PDCCH common search space set for multicast message search space configuration using RRC messages, the association between PDCCH monitoring occasions and SSB block indices for a Type N PDCCH common search space set is the same as the association between PDCCH monitoring occasions and Type 0 PDCCH common search spaces, and The number of PDCCH candidates for each CCE aggregation level in the common search space set of PDCCHs of class N is determined by at least one of the following methods: table lookup, Information on the common search space set of PDCCH of Class N, and / or information on search spaces identified as common types, Search space number, The first instruction information used to indicate the first time symbol in the control resource set within a single slot used for monitoring the PDCCH of a multicast message. Second instruction information used to specify the monitoring period and time offset amount used for monitoring the PDCCH monitoring occasion of multicast messages, Third directive information used to indicate the start symbol and / or duration in one monitoring cycle used for monitoring occasions of the PDCCH of multicast messages, A fourth directive information in bitmap format that indicates the monitoring time slot and / or monitoring time symbol used for monitoring occasions of the PDCCH of multicast messages, A fifth directive in bitmap format that indicates the monitoring time symbol in one time slot used for monitoring occasions of the PDCCH of multicast messages, A sixth instruction information used to indicate the start symbol and / or duration of one time slot used for monitoring occasions of the PDCCH of multicast messages, and This includes at least one of seven directive pieces of information used to indicate an index of the control resource set associated with this search space.

[0279] Based on the PDCCH Search Space set, a set of PDCCH candidates for monitoring by the terminal is defined, and the search space set may be a common search space set or a search space set specific to the terminal. The terminal uses a common search space set of TypeN-PDCCH, which is a combination of PDCCH-ConfigCommon (PDCCH common settings) and X-SearchSpace settings, and is used for configuring the DCI format where the CRC is scrambled by multicast-RNTI in the primary cell. If the UE is not provided with the higher-level parameter MB-SearchSpace for the type x-PDCCH common search space set, the association between the PDCCH monitoring occasions and the SS / PBCH block index for the type X-PDCCH common search space set is the same as the association for the TYPE 0-PDCCH common monitoring occasions, and the X-PDCCH common search space set allows the Control Channel Element (CCE) aggregation level and the number of PDCCH candidates for each CCE aggregation level in the X-PDCCH common search space set to be found by table lookup. Based on the X-Search Space defined by the protocol and the monitoring occasions of the first PDCCH configured by RRC signaling, the monitoring occasions of the PDCCH for monitoring multicast scheduling information are determined, and / or the network determines whether the monitoring occasions of the PDCCH for multicast scheduling are the same as the RMSI, and PDCCH candidates are monitored in one or more search space sets of the X-PDCCH Common Search Space Set.

[0280] For each monitoring time slot and / or monitoring time symbol that indicates PDCCH monitoring occasions for multicast messages in bitmap format, for example, if there are two Monitoring-periodicity-PDCCH-slots, then each slot has eight PDCCH monitoring occasions (MO). Specifically, the RRC can define the start OFDM time symbol and which specific symbols need to be monitored. For example, if it is 001111011100000111101111000, then symbols #2, 3, 4, 5, #7, 8, 9, and 10 need to be monitored. Or, If there are two Monitoring-periodicity-PDCCH-slots, then within each slot there are four PDCCH monitoring occasions. The symbols to be monitored in the first slot are #2, 3, 4, and 5, and the symbols to be monitored in the second slot are #7, 8, 9, and 10. Specifically, the RRC can define the start OFDM time symbol and which specific symbols (e.g., 00111100000000000001111000) need to be monitored.

[0281] Selectively, the above method, The process includes the step of selecting one or more beams for receiving multicast scheduling information.

[0282] The SSB / CSI-RS is relevant to beam information.

[0283] In multibeam operation, the UE can assume that the same multicast scheduling message is repeated on all transmitted beams, and therefore the UE can select one or more beams to receive the multicast scheduling message.

[0284] Selectively, one multicast message occasion is a PDCCH monitoring occasion for one group of multicast messages. The occasion for one multicast message is the monitoring occasion for Y multicast messages in the PDCCH, where Y is determined based on the number of SSBs actually sent from the cell. MO is for a group of Y consecutive PDCCH monitors, where Y is determined based on the number of SSBs actually transmitted by the cell. Selectively, one multicast message occasion is a PDCCH monitoring occasion for one group of multicast messages. The monitoring occasion for the Zth PDCCH in a multicast message corresponds to the Zth SSB being sent, where Z is a positive integer.

[0285] As shown in Figure 8, Figure 8 is a flowchart of an information transmission method provided by an embodiment of the present disclosure, which is applied to network-side equipment and includes the following step 81.

[0286] Step 81: Within the repetition period of the multicast service and / or broadcast service control information, every t time domain units, n multicast service and / or broadcast service control information is sent to the terminal, where n and t are positive integers.

[0287] In the embodiments of this disclosure, control information for multiple multicast and / or broadcast services can be transmitted separately, thereby allowing a terminal to monitor the control information corresponding to the corresponding transmission time, and it is not necessary to receive control information for all multicast and / or broadcast services.

[0288] In the prior art, all multicast and / or broadcast control information is transmitted on a single MCCH. Furthermore, all multicast scheduling information in the prior art is transmitted on a single SC-MCCH, and embodiments of this disclosure introduce various multicast SC-MCCHs. SC-MCCH information for multiple multicasts broadcast from the network is generated by a Distribute Unit (DU) node and then transmitted to a Centralized Unit (CU) node for broadcasting. Before generating system information related to the SC-MCCH, the DU node needs to obtain information from the CU such as the TMGI, session identifier, UE of interest, and associated Quality of Service (QoS) related to the multicast service.

[0289] Selectively, within the repetition cycle of the multicast service and / or broadcast service control information, every t time domain units, before transmitting n multicast service and / or broadcast service control information to the terminal, the method further: The process includes a transmission step of transmitting first information to a terminal, wherein the first information is used to indicate a first transmission time, and the first transmission time is the transmission time within the corresponding time domain unit of the control information for the n multicast and / or broadcast services.

[0290] Selectively, the first information is Information for indicating the start time of the first transmission time, Information for indicating the duration of the first transmission time, and Information for indicating a first offset amount, including at least one piece of information such that the first offset amount is an offset amount between the first transmission time and the position of the SSB RMSI.

[0291] As shown in Figure 9, Figure 9 is a flowchart of an information receiving method provided by an embodiment of the present disclosure, the method being applied to a terminal, and includes the following step 91.

[0292] Step 91: The network device receives n multicast and / or broadcast service control information every t time domain units within the repetition period of multicast and / or broadcast service control information, where n and t are positive integers.

[0293] In conventional technology, all multicast and / or broadcast control information is transmitted through a single MCCH.

[0294] In the embodiments of this disclosure, control information for multiple multicast and / or broadcast services can be transmitted separately, thereby allowing a terminal to monitor the control information corresponding to the corresponding transmission time, and it is not necessary to receive control information for all multicast and / or broadcast services.

[0295] Selectively receiving n multicast and / or broadcast service control information transmitted from network-side equipment at intervals of t time domain units within the repetition cycle of multicast and / or broadcast service control information is: Within the aforementioned repetition period, time-domain units corresponding to control information for multicast services and / or broadcast services are acquired. This includes monitoring control information for the corresponding multicast and / or broadcast services in the aforementioned time-domain unit.

[0296] Selectively, the time-domain unit is SFN mod sc-mcch-RepetitionPeriod=sc-mcch-Offset+(sc-mcch-Repetition Period)

number

[0297] In embodiments of this disclosure, when a network-side device transmits control information for multicast and / or broadcast services for n multicast and / or broadcast services every t time domain units within the repetition cycle of the control information for multicast and / or broadcast services, the terminal can derive the occurrence time of the SC-MCCH for the corresponding group based on the ID number of a different group, and thereby receive the SC-MCCH only at the occurrence time and not at other times.

[0298] The aforementioned time-domain unit may be a wireless frame.

[0299] Selectively receiving n multicast and / or broadcast service control information transmitted from network-side equipment at intervals of t time domain units within the repetition cycle of multicast and / or broadcast service control information is: Receiving the first information transmitted from the network-side device, and The second transmission time includes receiving control information for n multicast and / or broadcast services, wherein the first information is used to indicate the second transmission time, and the second transmission time is the transmission time of the control information for the n multicast and / or broadcast services within the corresponding time domain units.

[0300] In embodiments of the present disclosure, the terminal further acquires specific time slots and / or symbols to be monitored within the radio frame that needs to be monitored. A specific PDCCH monitoring time slot within a radio frame may point to the first time symbol in the control resource set within a time slot for PDCCH monitoring.

[0301] If there are two Monitoring-periodicity-PDCCH-slots, then each slot has eight PDCCH monitoring occasions (MOs). Specifically, the RRC can define the start OFDM time symbol and which specific symbols need to be monitored. For example, if the time is 001111011100000111101111000, then symbols #2, 3, 4, 5, #7, 8, 9, and 10 need to be monitored. Or, If there are two Monitoring-periodicity-PDCCH-slots, then within each slot there are four PDCCH monitoring occasions. The symbols to be monitored in the first slot are #2, 3, 4, and 5, and the symbols to be monitored in the second slot are #7, 8, 9, and 10. Specifically, the RRC can define the start OFDM time symbol and which specific symbols (e.g., 00111100000000000001111000) need to be monitored.

[0302] Selectively, the first information is Information for indicating the start time of the second transmission time, Information for indicating the duration of the second transmission time, and Information for indicating a first offset amount, the information being that the first offset amount is an offset amount between the second transmission time and the position of the SSB RMSI.

[0303] Specifically, the specific monitoring occasion within a single radio frame can be determined by defining the start symbol and duration. Here, the duration can be defined in CORESET-time-duration (Control Resource Set Duration). For example, the start symbols are #2 and #7, and the duration is four symbols. Alternatively, the SC-MCCH position can be derived based on the period and position information of the SSB transmitted by the RRC by defining the offset amount from the position of the SSB RMSI.

[0304] Similarly, this method can also be applied to reading SC-PTM information from idle and inactive UEs.

[0305] As shown in Figure 10, Figure 10 is a flowchart of a resource configuration method provided by an embodiment of the present disclosure, which is applied to network-side equipment and includes the following step 101.

[0306] Step 101: Send the configuration information to the terminal. The aforementioned configuration information is used to indicate a first symbol information and / or a second symbol information in a single time slot, wherein the first symbol is a symbol for transmitting unicast information, and the second symbol is a symbol for transmitting multicast information and / or broadcast information. The first symbol information is the number of time symbols and / or PRBs occupied by the first symbol, The second symbol information is the number of time symbols and / or PRBs occupied by the second symbol.

[0307] Selectively, the configuration information is further used to indicate that a row of reference signals has been inserted for every y symbols in the time slot, and / or that the configuration information is further used to indicate that a reference signal has been inserted for every x subcarriers in the frequency domain corresponding to the time slot, wherein the reference signals are reference signals used for multicast and / or broadcast.

[0308] The reference signal may be an SSB of one cell or a set of SSBs, or a shared SSB or set of SSBs in a multicast and / or broadcast area, and / or Selectively, the reference signal may be a unified CSI-RS or a set of CSI-RS provided to terminals in a multicast and / or broadcast group, or it may be a shared CSI-RS or set of CSI-RS in a multicast and / or broadcast area.

[0309] It is necessary to selectively exchange the reference signal information between different network nodes. The aforementioned x and y are positive integers, where x is determined based on the subcarrier interval and y is determined based on the subcarrier interval. The unicast information includes at least one of a reference signal, control signaling, and data corresponding to the unicast. The multicast information includes at least one of a reference signal, control signaling, and data corresponding to multicast. The broadcast information includes at least one of a reference signal, control signaling, and data corresponding to the broadcast.

[0310] Selectively, x and y are positive integers, where x is determined based on the subcarrier interval and y is further determined based on the measurement accuracy.

[0311] In current MBMS systems, MCCH messages can only be transmitted via Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) subframes. MBSFN subframes are dedicated subframes that can transmit only one data block. When a UE reads an MBSFN subframe at the appropriate time, it can obtain an MCCH message. Because an MBSFN subframe can only transmit one data block, that single data block may be used to transmit an MCCH message or other data. However, if the MCCH message cannot occupy all of the MBSFN subframe's resources, other data cannot be transmitted to the MBSFN subframe, resulting in wasted resources.

[0312] Furthermore, MBSFNs are divided into two types: dedicated carrier MBSFNs and unicast mixed carrier MBSFNs. The design of the MBSFN reference signal (RS) has special requirements. In a single radio frame of a mixed carrier MBSFN system, generally, most resources are used for unicast services, and only individual subframes are used for MBSFN services. A typical scenario is that an isolated MBSFN subframe is inserted within a series of unicast subframes. As a result, a terminal receiving this MBSFN subframe cannot perform interpolation channel estimation between the RSs of adjacent subframes, as it would when receiving a unicast signal. Therefore, the design of the MBSFN RS must be able to support channel estimation within a single isolated subframe. In the embodiments of this disclosure, the disclosure breaks away from the method of using MBSFN subframes as the smallest design unit in LTE and uses MBSFN time slots as the smallest design unit. This is because, although 5GNR supports multiple subcarrier intervals, the length of the radio frame and subframe are the same under different subcarrier interval settings. The radio frame length is 10 ms, and the subframe length is 1 ms. The number of time slots in each subframe differs. In a normal cyclic prefix (CP), the number of symbols in each time slot is the same, and each is 14. That is, the number of time symbols in one subframe of an NR differs, but the number of time symbols in each time slot is the same. Of the 14 time symbols, b time symbols are taken and unicast PDCCH, CSI-RS, and Demodulation Reference Signal (DM-RS) is transmitted, and then 14-b time symbols are used to transmit the MBMSFN reference signal, control channel, and data channel. b can be determined based on the required measurement accuracy, the size of the bandwidth of different frequency bands, and the multicast service load.Furthermore, the positions of these b time symbols may be fixedly defined, for example, as the preceding b, the following b, or the intermediate b, or their specific positions may be indicated by signaling. MBSFN-SlotConfig::=SEQUENCE{ radioframeAllocationPeriod ENUMERATED {n1, n2, n4, n8, n16, n32}, radioframeAllocationOffset INTEGER (0..7), slotAllocation CHOICE { oneFrame BIT STRING (SIZE(6)) of symbolAllocation, fourFrames BIT STRING (SIZE(24) of symbolAllocation) } }-- ASN1STOP

[0313] When a terminal of an adjacent cell measures an adjacent cell, only the unicast reference signal of these b time symbols may be measured.

[0314] In an MBSFN subframe, the first and second symbols typically employ a CP (Control Panel) and retain a unicast pilot, allowing them to be used for channel transmission such as PDCCH, Physical Control Format Indicator Channel (PCFICH), and Physical Hybrid ARQ Indicator Channel (PHICH). Other symbols in the subframe are used for MBSFN signal transmission.

[0315] On the other hand, depending on the specific subcarrier spacing, one MBSFN reference signal (RS) is inserted for every x subcarriers in the frequency domain, and one column of RS is inserted for every y OFDM symbols in the time domain.

[0316] Due to differences in measurement accuracy, SCS, and PRB width, the RS insertion interval differs across different SCSs; a wider SCS spacing results in a lower RS ​​density. The density of the reference signal of the subcarrier is also considered. For time symbols, the reference signal density is further considered. RS can play a role in channel demodulation in 5G MBMS.

[0317] The integration of multiple cells significantly increases the number of multipaths, making the frequency selectivity of MBSFN signals much greater than that of unicast signals, thus requiring a larger RS ​​frequency domain density. However, the time symbol lengths of different subcarrier intervals are also different.

[0318] Therefore, x, y, and b all correspond to the numerical values ​​of the subcarrier interval. This correspondence can be determined in the form of a table. Alternatively, it is set by RRC message / MAC CE / PDCCH signaling. Alternatively, after defining multiple correspondence tables and corresponding index numbers, the index numbers are set using RRC messages / MAC CE / PDCCH signaling. Alternatively, after setting up tables with multiple correspondences and corresponding index numbers using RRC signaling, the index numbers can be set using MAC CE / PDCCH signaling.

[0319] As shown in Figure 11, Figure 11 is a flowchart of a resource configuration method provided by an embodiment of the present disclosure, which is applied to a terminal and includes the following step 111.

[0320] Step 111: Receive configuration information sent from the network-side device. The configuration information transmitted to the terminal is used to indicate a first symbol information and / or a second symbol information in one time slot, wherein the first symbol is a symbol for transmitting unicast information, and the second symbol is a symbol for transmitting multicast information and / or broadcast information. The first symbol information is the number of time symbols and / or PRBs occupied by the first symbol, The second symbol information is the number of time symbols and / or PRBs occupied by the second symbol.

[0321] Selectively, the configuration information is further used to indicate that a row of reference signals has been inserted for every y symbols in the time slot, and / or that the configuration information is further used to indicate that a reference signal has been inserted for every x subcarriers in the frequency domain corresponding to the time slot, wherein the reference signals are reference signals used for multicast and / or broadcast.

[0322] Selectively, the reference signal may be an SSB of one cell or a set of SSBs, or a shared SSB or set of SSBs in a multicast and / or broadcast area, and / or Selectively, the reference signal may be a unified CSI-RS or a set of CSI-RS provided to terminals in a multicast and / or broadcast group, or it may be a shared CSI-RS or set of CSI-RS in a multicast and / or broadcast area.

[0323] It is necessary to selectively exchange the reference signal information between different network nodes. The aforementioned x and y are positive integers, where x is determined based on the subcarrier interval and y is determined based on the subcarrier interval. The unicast information includes at least one of a reference signal, control signaling, and data corresponding to the unicast. The multicast information includes at least one of a reference signal, control signaling, and data corresponding to multicast. The broadcast information includes at least one of a reference signal, control signaling, and data corresponding to the broadcast.

[0324] Selectively, x and y are positive integers, where x is determined based on the subcarrier interval and y is further determined based on the measurement accuracy.

[0325] As shown in Figure 12, Figure 12 is a flowchart of an information measurement method provided by an embodiment of the present disclosure, which is applied to a terminal and includes the following steps 121.

[0326] Step 121: Receive resource configuration information transmitted from a network-side device, which is resource configuration information for the multicast service and / or broadcast service of an adjacent cell.

[0327] Step 122: Measure or not measure the resource corresponding to the resource configuration information.

[0328] In the embodiments of this disclosure, MBSFN configuration information is exchanged between base stations and / or cells, or the base station and / or cell obtains MBSFN configuration information of adjacent cells from the network management unit. The base station and / or cell then notifies terminals of the MBSFN configuration information of adjacent cells via signaling, thus eliminating the need to transmit unicast signals and channel information in MBSFN unit resource blocks. When a terminal measures the signal quality of an adjacent cell, it ignores the MBSFN resources, or, if the terminal has MBMS services, it measures only the MBSFN resources.

[0329] The step of selectively measuring or not measuring the resource corresponding to the resource configuration information is: If the terminal has only unicast services, the resource corresponding to the resource configuration information will not be measured. If the terminal has only multicast and / or broadcast services, measure the resources corresponding to the resource configuration information, or If the terminal has unicast services, multicast services, and / or broadcast services, this includes measuring the resources corresponding to the resource configuration information.

[0330] In the embodiments of this disclosure, a terminal can measure the corresponding MBSFN resources for a specific MBMS service. If the UE has a unicast service, the UE ignores these MBSFN resources when measuring the signal quality of adjacent cells. If the UE has both a unicast service and an MBMS service, it reports measurement information for both types of resources.

[0331] The unicast service is configured on a dedicated activated BWP, the multicast service is configured on the initial BWP, or on a BWP associated with the initial BWP, and the system message indicates the relationship between the BWP that sends the multicast service and the initial BWP, for example, the offset relationship between Corset and Search space.
