Description

[0002] User Equipment (UE, also known as terminal) can be configured with multiple Group Radio Network Temporary Identifiers (G-RNTI). However, in the carrier aggregation scenario, there may be multiple service cells transmitting the same multicast / broadcast service (MBS) at the same time or multiple MBSs on one service cell. In order to receive the multicast service, the terminal needs to monitor all configured G-RNTIs on each service cell. Even if the MBS service corresponding to a certain G-RNTI is not sent on a certain service cell, the terminal needs to monitor the G-RNTI on the service cell, which will cause unnecessary terminal power consumption.

[0096] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The information monitoring, transmission method, device, terminal and network equipment provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0097] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1 As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (User Equipment, UE), for example: it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device).

The above-mentioned base station 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0098] First, based on the technical solution provided in this application, some technical terms that may be involved are introduced.

[0099] As an important service type, Multimedia Broadcast Multicast Service (MBMS) has existed for a long time. However, it currently only supports unicast services. In view of the importance of MBMS services to certain vertical fields (such as Internet of Vehicles and public safety), support for MBMS (called MBS in 5G, and will be referred to as MBS in the following) will be added.

[0100] MBS is divided into multicast service (carried on a multicast session, hereinafter referred to as multicast service or multicast session) and broadcast service. Among them, user equipment (UE, also known as terminal) in any radio resource control (RRC) state can receive broadcast service. Multicast service only supports UE in RRC connected state.

[0101] When a UE receives a multicast session in a connected state, the network sends the multicast configuration required for receiving the multicast session to the UE through a dedicated RRC message. Currently, for a UE configured with carrier aggregation, only one serving cell can be configured with the Common Frequency Resource (CFR) for multicast reception, and the UE can be configured with one to multiple G-RNTIs.

[0102] Based on the analysis, an embodiment of the present application provides an information monitoring and transmission method, apparatus, terminal and network equipment to reduce the power consumption of a terminal configured with carrier aggregation when receiving multicast broadcast services.

[0103] Among them, 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.

[0104] like Figure 2 As shown, the embodiment of the present application provides an information monitoring method, which is executed by a terminal and includes:

[0105] Step S201: determining whether configuration information sent by a network device is received, wherein the configuration information is used to indicate a mapping relationship between a group radio network temporary identifier G-RNTI and at least two serving cells configured for the terminal.

[0106] It should be noted that a carrier aggregation terminal will be configured with at least two serving cells, namely, a primary serving cell and at least one secondary serving cell.

[0107] Step S202, when the configuration information is received, using the G-RNTI corresponding to the first service cell in the mapping relationship, monitors the control information of the multicast broadcast service encrypted by the G-RNTI on the first service cell, and the first service cell belongs to at least one of the service cells configured for the terminal.

[0108] It should be noted that the multicast broadcast service is MBS, and it can be understood that the terminal can receive the multicast service in this way, and can also receive the broadcast service in this way.

[0109] It should be noted that the embodiment of the present application, based on the mapping relationship between G-RNTI and service cell, enables the terminal to know which G-RNTI-encrypted multicast broadcast service control information needs to be monitored on each service cell, so as to monitor the control information of specific multicast broadcast services on the corresponding service cell, thereby avoiding blind detection of multicast broadcast services and saving terminal power consumption.

[0110] Optionally, in one implementation, the configuration information includes at least one of the following:

[0111] A11. first indication information, where the first indication information is used to indicate a G-RNTI corresponding to each serving cell configured for the terminal;

[0112] It should be noted that this method can be understood as the network device configuring the corresponding G-RNTI for each service cell configured for the terminal; for example, the network device configures a correspondence mapping table, the first field in the table is the service cell identifier, and the corresponding second field is the G-RNTI corresponding to the service cell. The terminal can find out which G-RNTIs correspond to the service cell through a certain service cell identifier.

[0113] Optionally, in one implementation, the first indication information is transmitted in at least one of the following forms:

[0114] A111. Transmit the first indication information through the G-RNTI configuration add modification list (g-RNTI-ConfigToAddModList) element field;

[0115] In this case, it can be understood as adding the first indication information in g-RNTI-ConfigToAddModList.

[0116] It should be noted that the g-RNTI-ConfigToAddModList is located in the cell media access control cell group configuration (MAC-CellGroupConfig).

[0117] A112. Transmitting the first indication information through a primary cell configuration (SpCellConfig) element field and / or a secondary cell configuration (SCellConfig) element field, where the first indication information is determined by a G-RNTI configuration indication added to the primary cell configuration element field and / or the secondary cell configuration element field;

[0118] It should be noted that the G-RNTI configuration indication is used to indicate the G-RNTI corresponding to the primary cell or the secondary cell.

[0119] This method can be understood as adding the G-RNTI configuration indication in SpCellConfig and / or SCellConfig to indicate the first indication information to the terminal.

[0120] A113. Transmit the first indication information through a CFR multicast configuration (CFR-ConfigMulticast) element field, where the first indication information is determined by a G-RNTI configuration indication added to the CFR multicast configuration element field;

[0121] This method can be understood as adding the G-RNTI configuration indication in CFR-ConfigMulticast to indicate the first indication information to the terminal.

[0122] A12. second indication information, where the second indication information is used to indicate a serving cell corresponding to each G-RNTI configured for the terminal;

[0123] It should be noted that this method can be understood as the network device configuring the corresponding service cell for each G-RNTI configured for the terminal; for example, the network device configures a correspondence mapping table, the first field in the table is the G-RNTI identifier, and the corresponding second field is the service cell corresponding to the G-RNTI. The terminal can find out which service cells correspond to the G-RNTI through a certain G-RNTI identifier.

[0124] Optionally, in this case, the terminal generally configures each G-RNTI to correspond to a primary serving cell or to correspond to all serving cells.

[0125] It should be noted that in this case, the terminal decides whether to monitor a certain G-RNTI on the primary serving cell or monitor a certain G-RNTI on all serving cells based on the instruction of the network device.

[0126] Optionally, in an implementation manner, the implementation manner of using the G-RNTI corresponding to the first serving cell in the mapping relationship to monitor the control information of the multicast broadcast service scrambled by the G-RNTI on the first serving cell includes at least one of the following:

[0127] B11. When the first target G-RNTI corresponds to the primary serving cell, using the first target G-RNTI, monitoring control information of the multicast broadcast service scrambled by the first target G-RNTI on the primary serving cell;

[0128] It should be noted that, when the network device only instructs to monitor a specific G-RNTI on the primary serving cell, the terminal only needs to monitor the control information of the multicast broadcast service scrambled by the G-RNTI on the primary serving cell.

[0129] B12. When the second target G-RNTI corresponds to at least two serving cells configured for the terminal, using the second target G-RNTI to monitor control information of the multicast broadcast service scrambled by the second target G-RNTI on the activated serving cell;

[0130] It should be noted that when the network device instructs to monitor a specific G-RNTI on multiple service cells of carrier aggregation, the terminal needs to monitor the control information of the multicast broadcast service encrypted by the G-RNTI on the activated service cell in the indicated service cell.

[0131] For example, when the network device instructs to monitor a specific G-RNTI on all serving cells of the carrier aggregation, the terminal needs to monitor the control information of the multicast broadcast service scrambled by the G-RNTI on the activated serving cells among all the indicated serving cells.

[0132] Optionally, in an implementation manner, the mapping relationship between the G-RNTI and at least two serving cells configured for the terminal includes at least one of the following:

[0133] The mapping relationship between C11, G-RNTI and the identity of the serving cell;

[0134] C12, mapping relationship between G-RNTI and serving cell index;

[0135] C13, the mapping relationship between G-RNTI and the number of the serving cell in the serving cell configuration index list.

[0136] That is, the serving cell may be indicated by an identifier, an index and / or a number in a serving cell configuration index list.

[0137] Optionally, in one implementation, the method further includes:

[0138] In case that the configuration information is not received, control information of the multicast broadcast service scrambled by at least one G-RNTI configured for the terminal is respectively monitored on at least two serving cells configured for the terminal.

[0139] In this case, it can be understood that if the terminal does not receive the configuration information of the network device, in order to ensure that the terminal can receive multicast broadcast services, the terminal needs to listen to the control information of each G-RNTI-scrambled multicast broadcast service in each service cell of the configured carrier aggregation.

[0140] Optionally, in one implementation, the implementation of monitoring control information of a multicast broadcast service scrambled by at least one G-RNTI configured for the terminal includes:

[0141] Determine a serving cell configured with CFR among at least two serving cells configured for the terminal;

[0142] In the determined service cell configured with the CFR, control information of the multicast broadcast service scrambled by at least one G-RNTI configured for the terminal is monitored.

[0143] In this case, it can be understood that if no configuration information is received, the control information of each G-RNTI-scrambled multicast broadcast service is monitored separately only in the service cell configured with CFR.

[0144] The specific application examples of the embodiments of the present application are described below.

[0145] Application scenario 1: The terminal receives the MBS based on the first indication information

[0146] The specific implementation process includes:

[0147] Step S11: The network device sends configuration information to the connected terminal, where the configuration information includes first indication information;

[0148] This can be achieved by at least one of the following:

[0149] D11. Add the first indication information to the g-RNTI-ConfigToAddModList element field of the existing cell MAC-CellGroupConfig.

[0150] D12. Add G-RNTI configuration information to the existing cell SpCellConfig and / or SCellConfig

[0151] D13. Add G-RNTI configuration information in the existing cell CFR-ConfigMulticast.

[0152] Step S12: The terminal receives the configuration information sent by the network, and uses the G-RNTI corresponding to the first serving cell in the mapping relationship to monitor the control information of the multicast broadcast service scrambled by the G-RNTI on the first serving cell;

[0153] That is to say, the terminal first determines which G-RNTI should be monitored on which service cell based on the configuration information; then monitors the control information of the MBS encrypted by the corresponding G-RNTI on the corresponding service cell, determines the transmission resource location of the MBS service data through the control information, and receives the MBS service data based on the transmission resource location.

[0154] Application scenario 2: The terminal receives the MBS based on the second indication information

[0155] The specific implementation process includes:

[0156] Step S21: The network sends configuration information to the connected terminal, where the configuration information includes second indication information; the indication information indicates whether the UE monitors the G-RNTI only on the PCell or on all serving cells.

[0157] Step S22: The terminal receives the configuration information sent by the network device, and uses the G-RNTI corresponding to the first serving cell in the mapping relationship to monitor the control information of the multicast broadcast service scrambled by the G-RNTI on the first serving cell;

[0158] That is to say, the terminal first determines whether a certain G-RNTI corresponds only to the primary service cell (PCell) or to all service cells based on the configuration information; if a certain G-RNTI corresponds only to the PCell, the UE only listens to the control information of the MBS encrypted by the G-RNTI on the PCell, determines the transmission resource location of the MBS service data through the control information, and receives the MBS service data according to the transmission resource location; if a certain G-RNTI corresponds to all service cells, the terminal listens to the control information of the MBS encrypted by the G-RNTI on all activated service cells, determines the transmission resource location of the MBS service data through the control information, and receives the MBS service data according to the transmission resource location.

[0159] Application Scenario 3: In the carrier aggregation scenario, no configuration information of network devices is received

[0160] The specific implementation process includes:

[0161] Step S31: The terminal in the RRC connected state determines a serving cell configured with CFR;

[0162] It should be noted that, in this step, the terminal in the RRC connected state first receives the MBS configuration, which includes the G-RNTI configuration and the CFR configuration; and then determines the serving cell configured with the CFR based on the MBS configuration.

[0163] Step S32: The terminal monitors control information of the multicast broadcast service scrambled by at least one G-RNTI configured for the terminal on all serving cells configured with CFR;

[0164] That is to say, in this case, the terminal needs to listen to the control information of the MBS encrypted by each G-RNTI on all service cells configured with CFR, determine the transmission resource location of the MBS service data through the control information, and receive the MBS service data according to the transmission resource location.

[0165] In summary, the embodiment of the present application proposes a method in which a terminal under carrier aggregation receives the MBS corresponding to the corresponding G-RNTI on the corresponding service cell according to the configuration information. Compared with the current mechanism in which the terminal cannot distinguish which service cell sends which MBS corresponding to which G-RNTI, the embodiment of the present application can effectively reduce the power consumption of the terminal under carrier aggregation when receiving multicast broadcast services.
