Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a service receiving method, sending method and device. Background Art

[0002] The Multicast and Broadcast Service (MBS) service supports sending the same data to multiple user equipment (UE) using the same resources on the air interface, thereby improving the resource utilization of the air interface. In particular, for reduced capability UE (referred to as redcap UE) and normal UE, possible MBS service enhancements consider receiving normal UE and redcap UE on the same time-frequency resources, so as to further save the air interface resources occupied by the base station to send a certain MBS service.

[0003] However, in the current mechanism of scheduling MBS services with Downlink Control Information (DCI), the frequency domain resource location of the base station scheduling MBS services depends on the Common Frequency Domain Resources (CFR) configuration. The base station configures different CFRs for normal UE and redcap UE. Since different CFR configurations may correspond to different frequency domain resource starting positions and lengths, after the terminal obtains the CFR configuration, it parses the frequency domain location indication information field in the DCI scheduling according to the starting position and length of the CFR. This will result in inconsistent parsing between normal UE and redcap UE for the same DCI scheduling, and thus the redcap UE will not be able to correctly parse the multicast broadcast services sent by the base station and will not be able to correctly receive the MBS services. Summary of the invention

[0067] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0068] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0069] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0070] For ease of understanding, some contents involved in the embodiments of the present application are described as follows:

[0071] In the initial version of the New Radio (NR) that supports MBS services, multicast services are only supported in the connected state, and broadcast services support terminals in the idle, inactive, and connected states. Whether for broadcast or multicast, the main consideration is normal UE, and the base station configures the common frequency domain resources CFR for receiving MBS services for normal terminals. Whether MBS services support redcap UE reception depends on the base station / terminal implementation.

[0072] The embodiments of the present application provide a service receiving method, a sending method and a device. The method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0073] like Figure 1 As shown, a service receiving method provided in an embodiment of the present application includes:

[0074] Step 101: A terminal obtains indication information sent by a network device, wherein the indication information is used to instruct a first type of terminal to parse relevant configuration of scheduling information of a multicast broadcast service, and the first type of terminal is a reduced capability Redcap terminal.

[0075] That is, the network device will send indication information to the terminal with reduced capability (redcap UE) to instruct the redcap UE to parse the relevant configuration of the scheduling information of the MBS. After the terminal obtains the indication information, if it is a redcap UE, it will execute the next step.

[0076] Step 102: The terminal parses the scheduling information according to the indication information to obtain frequency domain resources corresponding to the scheduling information.

[0077] In this step, when the terminal acts as a redcap UE, it will complete the parsing of the scheduling information according to the indication information obtained in step 101, and obtain the frequency domain resources used for the transmission of the multicast broadcast service.

[0078] Step 103: The terminal receives the multicast broadcast service on the frequency domain resources.

[0079] In this step, the terminal completes the reception of the multicast broadcast service using the frequency domain resources obtained in step 102 .

[0080] In this way, the terminal executes the above steps 101-103, and can obtain the indication information sent by the network device to learn the relevant configuration of the redcap UE to parse the scheduling information of the multicast broadcast service, so that when the terminal is a redcap UE, the scheduling information is parsed according to the indication information, and the frequency domain resources used for the transmission of the multicast broadcast service are obtained, and the reception of the multicast broadcast service is completed, avoiding the problem of not being able to correctly receive the MBS service due to the inability to correctly parse the scheduling information.

[0081] Optionally, the indication information includes at least one of the following:

[0082] The search space used by the first type of terminals;

[0083] The scrambling code used by the first type of terminals;

[0084] The service identifier of the multicast broadcast service supported by the first type of terminals;

[0085] The parsing mode indication used by the first type of terminal is used to instruct the first type of terminal to use a first parsing mode or a second parsing mode, wherein the first parsing mode is different from the second parsing mode.

[0086] That is, the indication information includes one or more of the above contents to assist the terminal to parse the scheduling information when it is a redcap UE, and complete the reception of the MBS service on the frequency domain resources for transmitting the MBS service.

[0087] It should be noted that, in this embodiment, the indication information can also be understood as information used to instruct the redcap UE to use a parsing method to parse the scheduling information.

[0088] Among them, the indication information can implicitly indicate (associate) the parsing method used by the redcap UE through the search space used by the redcap UE, the scrambling code, and the service identifier of the MBS service supported for reception. For example, the indication information includes that the search space used by the redcap UE is search space A. If the redcap UE monitors the scheduling information of the MBS service in the search space A, the scheduling information monitored in the search space A is parsed according to the parsing method used by the redcap UE to obtain the frequency domain resources for the MBS service transmission, and complete the reception of the MBS service. Alternatively, the indication information includes the scrambling code 1 used by the redcap UE. After the redcap UE receives the scheduling information in the search space for monitoring the MBS service, it needs to use the scrambling code 1 to descramble the scheduling information, and parse the scheduling information according to the parsing method used by the redcap UE to obtain the frequency domain resources for the MBS service transmission, and complete the reception of the MBS service. Alternatively, the indication information includes that the service identifier of the MBS service supported by the redcap UE is a temporary mobile group identifier (TMGI) 1. If the redcap UE receives the scheduling information of TMGI1, it needs to parse the scheduling information according to the parsing method used by the redcap UE.

[0089] In addition, the indication information may include an indication of the parsing method used by the redcap UE to explicitly indicate the parsing method used by the redcap UE when parsing the scheduling information. In one implementation, the indication information includes an independent 1-bit information as an indication of the parsing method used by the redcap UE; in one implementation, the indication of the parsing method used by the redcap UE may be jointly indicated with one or more of the search space, scrambling code, and service identifier. For example, for a certain TMGI, or for a certain scrambling code, or a certain search space, an additional 1-bit information is added as an indication of the parsing method used by the redcap UE, "1" indicates that the redcap UE uses the second parsing method, and "0" indicates that the redcap UE uses the first parsing method.

[0090] Optionally, in this embodiment, the parsing mode indicates association with at least one of the following:

[0091] Search space;

[0092] Scrambling code;

[0093] Service identifier of the multicast broadcast service.

[0094] That is to say, when the indication information includes an indication of the parsing method used by the first type of terminal, the indication of the parsing method is associated with at least one of the search space, the scrambling code and the service identifier of the MBS service. In this way, even if the indication information does not indicate other content or indicates part of the content, the redcap UE can complete the parsing based on the information associated with the indication of the parsing method. For example, when the indication information includes a 1-bit information indicating the parsing method used by the redcap UE, and indicates that the redcap UE uses the second parsing method, the terminal can determine which MBS services of the cell need to use the second parsing method to parse their scheduling information based on the service identifier associated with the 1-bit information; the terminal can also determine which scrambling codes need to be monitored for scheduling information corresponding to the scrambling codes associated with the 1-bit information to use the second parsing method for parsing; the terminal can also determine which search spaces need to be monitored for scheduling information based on the search space associated with the 1-bit information to use the second parsing method for parsing.

[0095] Optionally, in this embodiment, the terminal parses the scheduling information according to the indication information to obtain the frequency domain resources corresponding to the scheduling information, including:

[0096] The terminal uses the common frequency domain resource CFR configuration of the second type of terminal as a reference configuration according to the indication information or the second parsing mode indicated in the indication information, and parses the frequency domain resource indication field in the scheduling information to obtain the frequency domain resource, wherein the second type of terminal is a terminal without reduced capability; or

[0097] The terminal uses the CFR configuration of the first type of terminal as a reference configuration, parses the frequency domain resource indication field in the scheduling information, and determines the position of the virtual resource block according to the indication information or the second parsing method indicated in the indication information; and obtains the frequency domain resources based on a mapping process from the virtual resource block position to the physical resource block.

[0098] That is, the network device instructs the redcap UE to adopt one of the above methods to implement the parsing of the scheduling information. That is, the second parsing method can be to use the CFR configuration of the normal UE as a reference configuration, parse the frequency domain resource indication field in the scheduling information to obtain the frequency domain resources; the second parsing method can also be to use the CFR configuration of the redcap UE as a reference configuration, parse the frequency domain resource indication field in the scheduling information, so as to first determine the virtual resource block position, and then obtain the frequency domain resources based on the mapping process of the virtual resource block position to the physical resource block.

[0099] Specifically, considering that the network device determines the frequency domain resource indication field in the scheduling information based on the CFR configuration of the normal UE, in the first mode, although the terminal is a redcap UE, it needs to know the CFR configuration of the normal UE, and use the CFR configuration of the normal UE as a reference configuration to parse the frequency domain resource indication field in the scheduling information to obtain the frequency domain resources for transmitting the MBS service. For example, if the frequency domain resource indication field indicates the second position after the starting position of the CFR, and the frequency domain resources of 3 consecutive positions, the terminal determines the frequency domain resources based on the starting position of the CFR indicated in the CFR configuration of the normal UE. In another mode, the terminal is a redcap UE, and uses the CFR configuration configured for it by the network device as a reference configuration to parse the frequency domain resource indication field in the scheduling information, first obtain the virtual resource block position, and then combine the mapping of the virtual resource block position to the physical resource block, and use the reverse mapping process of the virtual resource block position to the physical resource block, and finally obtain the frequency domain resources for transmitting the MBS service. For example, in the same frequency domain resource indication field as in the above example, the terminal first determines the virtual resource block position based on the starting position of the CFR indicated in the CFR configuration of the redcap UE, assuming that there is a deviation of 5 physical resource blocks in the mapping of the virtual resource block position to the physical resource block, then combined with the deviation of 5 physical resource blocks, the required frequency domain resources can be determined by the determined virtual resource block position.

[0100] In addition, optionally, in this embodiment, the first parsing method is to use the CFR configuration of the terminal itself as a reference configuration and parse the frequency domain resource indication field in the scheduling information to obtain the frequency domain resources.

[0101] Optionally, in this embodiment, the terminal obtains the indication information sent by the network device, including:

[0102] The terminal receives at least one of the following items carrying the indication information:

[0103] Radio Resource Control RRC reconfiguration message;

[0104] System information;

[0105] Control channel MCCH for broadcast services;

[0106] MCCH for multicast services;

[0107] Non-access stratum NAS message.

[0108] That is, the terminal receives the indication information, which may be receiving at least one of an RRC reconfiguration message, system information, a control channel (Main Control Channel, MCCH) for broadcast services, an MCCH for multicast services, and a non-access stratum (NonAccess Stratum, NAS) message. Of course, one or more of the received RRC reconfiguration message, system information, MCCH for broadcast services, MCCH for multicast services, and NAS messages carry the indication information. Accordingly, the network device sends the indication information to the terminal by sending at least one of the above items.

[0109] MCCH is a logical channel. The NAS message is included in the RRC reconfiguration message of the air interface.

[0110] It should be known that, in this embodiment, one implementation of the scheduling information is DCI, and the DCI is used to schedule the MBS service. The terminal parses the scheduling information, that is, parses the frequency domain resource indication field of the DCI.

[0111] It should also be known that, in this embodiment, the scrambling code may be a Group Radio Network Temporary Identifier (G-RNTI), or a Group Configured Scheduling RNTI (G-CS-RNTI), etc.

[0112] It should be noted that the terminal described in the embodiment of the present application is a redcap UE, that is, it is for redcap UE. If a normal UE receives the indication information, it does not need to use the parsing method used by the redcap UE to parse the scheduling information.

[0113] like Figure 2 As shown, an embodiment of the present application provides a service sending method, including:

[0114] Step 201: A network device sends indication information, where the indication information is used to instruct a first type of terminal to parse relevant configuration of scheduling information of a multicast broadcast service, where the first type of terminal is a reduced capability Redcap terminal.

[0115] In this way, the network device sends indication information to instruct the redcap UE to parse the relevant configuration of the MBS scheduling information for reducing the redcap UE, so that when the terminal is a redcap UE, it parses the scheduling information according to the obtained indication information, obtains the frequency domain resources used for MBS service transmission, and completes service reception.

[0116] Optionally, the method further comprises:

[0117] The network device sends the multicast broadcast service on the frequency domain resources corresponding to the scheduling information.

[0118] Therefore, after receiving the indication information and obtaining the frequency domain resources corresponding to the scheduling information, the terminal can receive the MBS service sent by the network device on the frequency domain resources.

[0119] Optionally, the indication information includes at least one of the following:

[0120] The search space used by the first type of terminals;

[0121] The scrambling code used by the first type of terminals;

[0122] The service identifier of the multicast broadcast service supported by the first type of terminals;

[0123] The parsing mode indication used by the first type of terminal is used to indicate whether the first type of terminal uses a first parsing mode or a second parsing mode, wherein the first parsing mode is different from the second parsing mode.

[0124] That is, the indication information includes one or more of the above contents to assist the terminal to parse the scheduling information when it is a redcap UE, and complete the reception of the MBS service on the frequency domain resources for transmitting the MBS service.

[0125] It should be noted that, in this embodiment, the indication information can also be understood as information used to instruct the redcap UE to use a parsing method to parse the scheduling information.

[0126] Among them, the indication information can implicitly indicate (associate) the parsing method used by the redcap UE through the search space used by the redcap UE, the scrambling code, and the service identifier of the MBS service supported for reception. For example, the indication information includes that the search space used by the redcap UE is search space A. If the redcap UE monitors the scheduling information of the MBS service in the search space A, the scheduling information monitored in the search space A is parsed according to the parsing method used by the redcap UE to obtain the frequency domain resources for the MBS service transmission, and complete the reception of the MBS service. Alternatively, the indication information includes the scrambling code 1 used by the redcap UE. After the redcap UE receives the scheduling information in the search space for monitoring the MBS service, it needs to use the scrambling code 1 to descramble the scheduling information, and parse the scheduling information according to the parsing method used by the redcap UE to obtain the frequency domain resources for the MBS service transmission, and complete the reception of the MBS service. Alternatively, the indication information includes that the service identifier of the MBS service supported by the redcap UE is a temporary mobile group identifier (TMGI) 1. If the redcap UE receives the scheduling information of TMGI1, it needs to parse the scheduling information according to the parsing method used by the redcap UE.

[0127] In addition, the indication information may include an indication of the parsing method used by the redcap UE to explicitly indicate the parsing method used by the redcap UE when parsing the scheduling information. In one implementation, the indication information includes an independent 1-bit information as an indication of the parsing method used by the redcap UE; in one implementation, the indication of the parsing method used by the redcap UE may be jointly indicated with one or more of the search space, scrambling code, and service identifier. For example, for a certain TMGI, or for a certain scrambling code, or a certain search space, an additional 1-bit information is added as an indication of the parsing method used by the redcap UE, "1" indicates that the redcap UE uses the second parsing method, and "0" indicates that the redcap UE uses the first parsing method.

[0128] Optionally, the parsing mode indication is associated with at least one of the following:

[0129] Search space;

[0130] Scrambling code;

[0131] Service identifier of the multicast broadcast service.

[0132] That is to say, when the indication information includes an indication of the parsing method used by the first type of terminal, the indication of the parsing method is associated with at least one of the search space, the scrambling code and the service identifier of the MBS service. In this way, even if the indication information does not indicate other content or indicates part of the content, the redcap UE can complete the parsing based on the information associated with the indication of the parsing method. For example, when the indication information includes a 1-bit information indicating the parsing method used by the redcap UE, and indicates that the redcap UE uses the second parsing method, the terminal can determine which MBS services of the cell need to use the second parsing method to parse their scheduling information based on the service identifier associated with the 1-bit information; the terminal can also determine which scrambling codes need to be monitored for scheduling information corresponding to the scrambling codes associated with the 1-bit information to use the second parsing method for parsing; the terminal can also determine which search spaces need to be monitored for scheduling information based on the search space associated with the 1-bit information to use the second parsing method for parsing.

[0133] Optionally, the network device sends the indication information, including:

[0134] The network device sends the indication information by at least one of the following:

[0135] RRC reconfiguration message;

[0136] System information;

[0137] MCCH for broadcast services;

[0138] MCCH for multicast services;

[0139] NAS message.

[0140] That is, the network device sends the indication information to the terminal, and the network device may send at least one of an RRC reconfiguration message, system information, MCCH for broadcast services, MCCH for multicast services, and NAS messages. Of course, one or more of the sent RRC reconfiguration message, system information, MCCH for broadcast services, MCCH for multicast services, and NAS messages carry the indication information. Then, the terminal obtains the indication information by receiving at least one of the above items.
