Description

[Technical Field]

[0001] The present application relates to the technical field of 5G multicast, and in particular to a method and apparatus for transmitting and receiving discontinuous reception commands. [Background technology]

[0002] In the prior art, considering the characteristic that data flow transmitted between a transmitting end and a receiving end is sudden, a discontinuous reception (DRX) scheme is proposed, in which a discontinuous reception cycle consisting of an on duration (active period) and an opportunity for DRX (sleep period) is set for a receiving end in an RRC_CONNECTED state, and when the receiving end is in the active period, it monitors a PDCCH (Physical Downlink Control Channel) and receives data transmitted from the transmitting end on a corresponding PDSCH (Physical Downlink Shared Channel), and when the receiving end is in the sleep period, it does not monitor the PDCCH or receive corresponding data. In other words, by setting a discontinuous reception scheme for the transmitting end and the receiving end in a communication system and controlling the receiving end to use a discontinuous reception cycle, when there is no data to be transmitted between the transmitting end and the receiving end, the receiving circuit of the receiving end is turned off / on intermittently and cyclically, thereby reducing the power loss of the receiving end and improving the battery life.

[0003] Accordingly, in the prior art, a discontinuous reception method is introduced for 5G unicast services to form a unified standard. Specifically, a receiving end receiving a 5G unicast service starts a drx-onDurationTimer timer when it enters an active period, and if a PDCCH scrambled by a C-RNTI (Cell-Radio Network Temporary Identifier) is monitored during the operation period of the drx-onDurationTimer timer, it correspondingly starts a drx-InactivityTimer timer and monitors whether a PDCCH scrambled by a C-RNTI is present in each subframe during the operation period of the drx-InactivityTimer timer. If the receiving end receives an indication information during the operation period of the drx-InactivityTimer timer, it restarts the drx-InactivityTimer timer to further extend the active period of the receiving end. If the receiving end receives a discontinuous reception command, it restarts the drx-onDurationTimer timer and When the rx-InactivityTimer timer stops running, the drx-InactivityTimer timer times out, or an intermittent reception command is received, if the receiving end does not have a short intermittent reception cycle set, it directly uses the long intermittent reception cycle; if the receiving end has a short intermittent reception cycle set, it uses the short intermittent reception cycle to start or restart the drx-ShortCycleTimer timer; when the drx-ShortCycleTimer timer times out, the receiving end uses the long intermittent reception cycle; if the receiving end receives a long intermittent reception command, it stops running the drx-ShortCycleTimer timer and uses the long intermittent reception cycle.

[0004] However, in the prior art, the discontinuous reception method for 5G multicast services has not yet been established, let alone a unified standard. This is because the transmission process of multicast services mainly uses the technology of transmitting data from one data source to multiple target receivers to achieve unified control of multiple receivers. However, in the existing unicast, based on the one-to-one technology, the transmitter sends a discontinuous reception command, and the receiver monitors and receives the PDCCH scrambled by C-RNTI during the active period, receives the discontinuous reception command, starts a corresponding timer, and uses the discontinuous reception period. If the existing technical solution for 5G unicast services is directly applied to multicast scenarios, that is, if a discontinuous reception command is indicated on the PDCCH scrambled by the C-RNTI and sent to each of a group of user equipments corresponding to reception of a certain multicast service, then on the one hand, the transmitting end needs to send multiple discontinuous reception commands to different receiving ends, respectively, resulting in a waste of resources. On the other hand, if the 5G standard directly introduces a discontinuous reception mode for multicast services based on the existing discontinuous reception mode for unicast services, and these two discontinuous reception modes are configured independently, then after receiving the discontinuous reception command, the receiving end will have difficulty distinguishing whether the command is for a unicast service or a multicast service, and will be unable to determine which configuration parameters corresponding to discontinuous reception to use. If the C-RNTI is directly replaced with the group radio network temporary identifier, then the specific operations performed by user equipment after receiving the discontinuous reception command, such as the received command structure, will need to be redefined and subdivided and designed. For these reasons, the prior art does not provide any corresponding technical suggestions, let alone any corresponding operation plans.

[0005] Therefore, there is currently an urgent need for a method for transmitting and receiving intermittent reception commands for multicast services. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0018] The present application will now be further described with reference to the drawings and specific examples, which are not intended to limit the present application.

[0019] 3GPP (registered trademark) (3rd Generation Partnership Project) has proposed multicast technology to make effective use of mobile network resources, enabling a single data source to transmit data to multiple target user devices, thereby realizing resource sharing in the core network and access network and improving the utilization of network resources, especially air interface resources. The multicast service defined by 3GPP not only realizes plain text low-speed message-based multicast and broadcast, but also realizes higher-speed multimedia service broadcast and multicast, and can provide a variety of rich video, audio, and multimedia services.

[0020] This application provides a method and device for discontinuous data reception for multicast services. It should be noted that the multicast service described in this application may be a groupcast service, a broadcast service, or may be called MBS (Multicast Broadcast Service), and this application does not limit this.

[0021] Among them, in the method for transmitting an intermittent reception command according to the present application, The transmitting end indicates an DNR command via a physical downlink control channel, and scrambles the physical downlink control channel with a radio network temporary identifier, the radio network temporary identifier corresponding to a multicast service and including a group radio network temporary identifier used to indicate a group of user equipments receiving the service; The transmitting end sends an intermittent receiving command.

[0022] In a further intermittent reception command transmission method according to the present application, The transmitting end indicates an discontinuous reception command through a physical downlink control channel, and scrambles the physical downlink control channel using a radio network temporary identifier; The transmitting end indicates a group wireless network temporary identifier, a temporary mobile group identifier, and / or a session identifier in the discontinuous reception command and / or the multiple access control subheader; The transmitting end sends an intermittent receiving command.

[0023] The transmission method of the present invention actually includes two methods. In the first transmission method, the transmitting end transmits a discontinuous reception command, in which the physical downlink control channel (PDCCH) indicating the discontinuous reception command is scrambled by a group radio network temporary identifier (GNR), which corresponds to a multicast service and is used to indicate a group of user equipments to receive the service.

[0024] In the (2) type transmission method, the transmitting end transmits an discontinuous reception command, and indicates a group wireless network temporary identifier and / or a temporary mobile group identifier and / or a session identifier in the discontinuous reception command, where the group wireless network temporary identifier and / or the temporary mobile group identifier and / or the session identifier correspond to at least one type of multicast service and are used to indicate a group of user equipments to receive the service.

[0025] Wherein, the Group Radio Network Temporary Identifier is used to indicate a group of user equipments receiving a certain multicast service, and for convenience of description in this application, it will be referred to as G-RNTI (Group-Radio Network Temporary Identifier), and in this application, the G-RNTI, the multicast service, the Temporary Mobile Group Identity (TMGI), and the group of user equipments receiving the service correspond to each other. The Discontinuous Reception Command is used to instruct the receiving end to receive the service in a discontinuous reception manner, and in this application, for convenience of description, it may be referred to as DRX command (Discontinuous Reception Command).

[0026] Accordingly, when the type (1) transmission method is adopted, the transmitting end scrambles the PDCCH indicating the discontinuous reception command with the G-RNTI, and the receiving end receiving the service corresponding to the G-RNTI acquires the PDCCH addressed by the corresponding G-RNTI when blindly detecting the PDCCH, acquires the DCI carried in the PDCCH, and finally receives the discontinuous reception command carried in the PDSCH indicated by the DCI. Meanwhile, the receiving end that does not receive the service will not receive the service, much less in a discontinuous reception manner, due to the PDCCH addressed by the G-RNTI that it cannot acquire, thereby achieving the purpose that the receiving end that receives the discontinuous reception command can receive the service corresponding to the G-RNTI in a discontinuous reception manner.

[0027] Accordingly, when the (2) type transmission method is adopted, the transmitting end indicates the G-RNTI in the discontinuous reception command it sends, and the receiving end receiving the service corresponding to the G-RNTI obtains the G-RNTI through the discontinuous reception command after receiving the discontinuous reception command, and receives the service corresponding to the G-RNTI in a discontinuous reception manner, thereby achieving the purpose that the receiving end receiving the discontinuous reception command can receive the service corresponding to the G-RNTI in a discontinuous reception manner.

[0028] Thus, for multicast services, the transmitting end can know in advance the settings, frequencies, and priority levels of different multicast services, and by exchanging information with the receiving end, the transmitting end can know in advance the power consumption status and service reception status of different receiving ends, etc., and by adopting the above-mentioned transmission method to send an intermittent reception command, it can control all user equipments corresponding to one or more services or some of the user equipments to receive the services in an intermittent reception manner, or it can control different user equipments to receive one or more services out of all the services they are receiving in an intermittent reception manner.

[0029] In addition, the G-RNTI can be regarded as a type of identifier, and the service identifier can be represented by a Session ID or a TMGI. Therefore, although these three have different meanings and are defined independently in the standard, they are in a mapping relationship with each other, and the mapping relationship between these three is set by the network.

[0030] There is a correspondence relationship between a G-RNTI (Group Radio Network Temporary Identifier), a Session ID (Session Identifier), a TMGI (Temporary Mobile Group Identifier), a service, and a group of user equipment receiving the service. Based on this, when the purpose of discontinuous reception is realized by the instruction content in the discontinuous reception command, the present application may directly implement it in the manner of "indicating G-RNTI in the discontinuous reception command, and the receiving end uses the discontinuous reception cycle corresponding to G-RNTI for the service corresponding to G-RNTI", or may use the Temporary Mobile Group Identifier TMGI and the Session Identifier Session ID instead of G-RNTI, i.e., "indicating Session ID in the discontinuous reception command, and the receiving end uses the discontinuous reception cycle corresponding to Session ID for the service corresponding to Session ID", "indicating TMGI in the discontinuous reception command, and the receiving end uses the discontinuous reception cycle corresponding to TMGI for the service corresponding to TMGI", or "indicating Session ID and TMGI in the discontinuous reception command, and the receiving end uses the discontinuous reception cycle corresponding to TMGI for the service corresponding to TMGI". The discontinuous reception command may be implemented in other ways, such as "indicating G-RNTI and Session ID in the discontinuous reception command, and the receiving end uses a discontinuous reception cycle corresponding to the service commonly corresponding to G-RNTI and Session ID," "indicating G-RNTI and Session ID in the discontinuous reception command, and the receiving end uses a discontinuous reception cycle corresponding to the service commonly corresponding to G-RNTI and Session ID," "indicating G-RNTI, TMGI and Session ID in the discontinuous reception command, and the receiving end uses a discontinuous reception cycle corresponding to the service commonly corresponding to G-RNTI, TMGI and Session ID," etc., all of which are equivalent technical solutions and can achieve the same technical effect. Therefore, when implementing the method of type (2), the present application may further include an operation of indicating TMGI and / or Session ID in the discontinuous reception command, and the transmitting end sending the discontinuous reception command.Accordingly, after receiving the discontinuous reception command, the receiving end obtains the TMGI and / or Session ID through the discontinuous reception command and receives the service corresponding to the TMGI and / or Session ID (which is also the service corresponding to the G-RNTI) in a discontinuous reception manner, so that the receiving end that receives the discontinuous reception command finally receives the service in a discontinuous reception manner. Whether the discontinuous reception command transmitted by the transmitting end indicates the G-RNTI or the TMGI and / or Session ID, the only difference is the content specified in the discontinuous reception command, and the remaining operations are the same. Therefore, in subsequent embodiments of the present application, the part indicating the TMGI and / or Session ID will not be repeated, but will be expanded to include the part indicating the G-RNTI, and accordingly, the part of obtaining the TMGI and / or Session ID indicated in the discontinuous reception command when performing a corresponding reception method will not be repeated.

[0031] In addition, there is a correspondence relationship between a G-RNTI (Group Radio Network Temporary Identifier), a Session ID (Session Identifier), a TMGI (Temporary Mobile Group Identifier), a service, and a user equipment identifier (i.e., C-RNTI) possessed by each of a group of user equipments receiving the service. Therefore, similarly, when the transmitting end achieves the purpose of enabling a receiving end receiving a service corresponding to the G-RNTI to receive a discontinuous reception command indicated by the G-RNTI, when performing the method (2), the present application further includes an operation of addressing a PDCCH indicating the discontinuous reception command with a C-RNTI corresponding to the receiving end. Accordingly, when the receiving end blindly detects the PDCCH, it can obtain the PDCCH addressed by its corresponding C-RNTI (Cell-Radio Network Temporary Identifier), obtain the DCI carried in the PDCCH, receive the discontinuous reception command carried in the PDSCH indicated by the DCI, and obtain the G-RNTI indicated in the discontinuous reception command, finally enabling the receiving end to receive the service corresponding to the G-RNTI in a discontinuous reception manner. It should be noted that the implementation of the type (2) method may employ an operation of scrambling the PDCCH indicating the discontinuous reception command with the G-RNTI, and the implementation of the type (2) method is not limited by the scrambling method. Here, the C-RNTI refers to a unique radio network temporary identifier configured by the transmitting end for the receiving end in the communication system and directly corresponding to the receiving end. The C-RNTI corresponds only to the receiving end itself and has no relation to the service being received by the receiving end, while the G-RNTI corresponds directly to a service and also corresponds to a group of user equipments that receive the service. Thus, although the user equipment and the receiving end are essentially the same, the present application also distinguishes between the commonly seen corresponding meanings and correspondences of different names, such as the transmitting end of a communication system typically describing a device that receives data transmitted from the transmitting end as the receiving end, and the service in a communication system typically describing a device that receives the service as the user equipment.Furthermore, in this application, a device that transmits a service is referred to as a "transmitting end" and a device that receives a service is referred to as a "receiving end," but there is no limitation on the specific devices of the transmitting end and the receiving end. For example, if this application is applied to a mobile terminal communication system, such as wireless communication of a mobile phone device, the transmitting end is a base station, and the receiving end and user equipment are both mobile phone devices. If this application is applied to another communication system, such as ad hoc network communication of a smart car, to realize software upgrade, the transmitting end is a smart car or base station V1 that transmits a software package, and the receiving end is a smart car V2 that receives the software package. The user equipment receiving a service means that the smart car V2 receives the software package and performs the upgrade.

[0032] As described above, the transmitting end can transmit a discontinuous reception command through the above-mentioned transmission method and control the receiving end to receive the service corresponding to the G-RNTI in a discontinuous reception manner.

[0033] This application is The receiving end receives a discontinuous reception command indicated by a physical downlink control channel addressed by a radio network temporary identifier including a G-RNTI, the physical downlink control channel corresponding to a type of multicast service and used to indicate a group of user equipments receiving the service; The receiving end provides a method for receiving an discontinuous reception command, including: after receiving the discontinuous reception command, using a discontinuous reception cycle corresponding to the G-RNTI for the service corresponding to the G-RNTI.

[0034] This application is The receiving end receives an intermittent reception command; The receiving end obtains a G-RNTI, a TMGI, and / or a Session ID indicated in the discontinuous reception command and / or a MAC subheader; The receiving end further provides a method for receiving an discontinuous reception command, including: after receiving the discontinuous reception command, using a corresponding discontinuous reception cycle for the service corresponding to the G-RNTI, and / or TMGI, and / or Session ID.

[0035] The receiving method of the present invention actually includes two types. In type (1) receiving method, the receiving end receives a discontinuous reception command, and addresses the PDCCH indicating the discontinuous reception command by a G-RNTI corresponding to at least one multicast service and used to indicate a group of user equipments receiving the service. After receiving the discontinuous reception command, the receiving end uses the discontinuous reception cycle corresponding to the G-RNTI for the service corresponding to the G-RNTI.

[0036] In the type (2) receiving method, the receiving end receives a discontinuous reception command corresponding to at least one multicast service and indicating a G-RNTI and / or TMGI and / or Session ID used to indicate a group of user equipments receiving the service. After receiving the discontinuous reception command, the receiving end uses the discontinuous reception cycle corresponding to the G-RNTI for the service corresponding to the G-RNTI. Note that this execution method only limits the content of the instruction in the discontinuous reception command, but does not limit the address method of the PDCCH indicating the discontinuous reception command. That is, when the type (2) receiving method is executed, whether the PDCCH addressed by the G-RNTI or the PDCCH addressed by the C-RNTI corresponding to the receiving end itself is monitored, the identifier (G-RNTI and / or TMGI and / or Session ID) in the discontinuous reception command is received and acquired, and finally, the receiving end that receives the service can receive the service corresponding to the identifier in a discontinuous reception manner. When executing the type (2) receiving method, the received discontinuous reception command may indicate TMGI, Session ID, TMGI and Session ID, G-RNTI and TMGI, G-RNTI and Session ID, or G-RNTI, TMGI and Session ID, and the receiving end obtains the identifier (G-RNTI and / or TMGI and / or Session ID) in the discontinuous reception command and uses the corresponding discontinuous reception cycle for the service corresponding to the identifier.

[0037] Specifically, the receiving end receives the service in a discontinuous reception manner according to the received discontinuous reception command; Among them, correspondingly, when adopting the type (1) receiving method, the receiving end blindly detects the PDCCH addressed by the G-RNTI based on the G-RNTI corresponding to the service being received by the receiving end, receives the DCI carried in the PDCCH, receives the discontinuous reception command carried in the PDSCH indicated by the DCI, and uses the discontinuous reception cycle corresponding to the G-RNTI for the service corresponding to the G-RNTI. For example, receiving ends d and e are both receiving service C. Therefore, when receiving data sent from the transmitting end, receiving ends d and e can both detect the PDCCH addressed by G-RNTI through blind detection, receive the DCI carried in the PDCCH, and obtain the discontinuous reception command carried in the PDSCH indicated by the DCI. Thus, for service C corresponding to G-RNTI, receiving ends d and e both use the discontinuous reception cycle corresponding to G-RNTI to receive data of service C in a discontinuous reception manner, that is, receiving ends d and e only turn on the receiving circuit during the active period of the discontinuous reception cycle to receive data of service C, and turn off the receiving circuit during the sleep period to not receive data of service C.

[0038] Whereas, when the receiving method (2) is adopted, the receiving end uses the discontinuous reception cycle corresponding to the G-RNTI for the service corresponding to the G-RNTI according to the G-RNTI indicated in the received discontinuous reception command. For example, when the receiving end d is simultaneously receiving multiple services, such as service C and service D, and the receiving end d finds that all the received discontinuous reception commands indicate only the G-RNTI corresponding to service C and no G-RNTI corresponding to service D, the receiving end uses the discontinuous reception cycle corresponding to G-RNT for service C, receives the data of service C in the discontinuous reception manner, and receives the data of service D in the normal continuous reception manner for service D.

[0039] Furthermore, when adopting the type (2) receiving method, the following operation may be performed: the receiving end directly addresses the PDCCH by the corresponding C-RNTI, and correspondingly, when the receiving end blindly detects the PDCCH, it can obtain the PDCCH addressed by the C-RNTI corresponding to itself, obtain the DCI carried in the PDCCH, receive the discontinuous reception command carried in the PDSCH indicated by the DCI, and obtain the G-RNTI indicated in the discontinuous reception command, so as to finally enable the receiving end to receive the service corresponding to the G-RNTI in a discontinuous reception manner.

[0040] As described above, the receiving end can receive the discontinuous reception command through the above-mentioned receiving method and use the discontinuous reception period corresponding to the G-RNTI, allowing the receiving end to receive the service corresponding to the G-RNTI in the discontinuous reception manner.

[0041] The present application provides a method for transmitting an intermittent reception command, and the intermittent reception command may be RRC (Radio Resource Control) layer information, or PHY (Physical Layer) information, or RLC (Radio Link Control) layer information, or PDCP (Packet Data Convergence Protocol) layer information, or MAC (Medium Access Control) layer information.

[0042] The present application provides a method for receiving an DRX command, where the DRX command received by a receiving end may be RRC layer information, or PHY information, or RLC layer information, or PDCP layer information, or MAC layer information.

[0043] Specifically, for example, if the discontinuous reception command is RRC layer information, parameters related to the discontinuous reception command and / or the long discontinuous reception command are set for the G-RNTI and / or the corresponding service. Each of the above parameters has two value assignment methods. For example, if the assigned value is 1, it indicates that the discontinuous reception command is enabled and the receiving end uses the discontinuous reception cycle corresponding to the G-RNTI after receiving it. If the assigned value is 0, it indicates that the discontinuous reception command is not enabled and the receiving end ignores the discontinuous reception information after receiving it. When the first type of transmission method and the first type of reception method are adopted, the PDCCH indicating the RRC layer message is scrambled with the G-RNTI. Accordingly, the RRC layer message is received by all receiving ends that receive the multicast service corresponding to the G-RNTI.

[0044] If the discontinuous reception command is a MAC layer message, the discontinuous reception command is a MAC CE (MAC Control Element), and accordingly, the discontinuous reception command may be described as a DRX command MAC CE (Discontinuous Reception Command MAC Control Element).

[0045] In addition, in a communication system, there are multiple multicast services and multiple G-RNTIs corresponding to user equipments receiving the multiple multicast services, and the discontinuous reception cycle corresponding to different G-RNTIs is different. That is, when a transmitting end sends a discontinuous reception command and a receiving end receives the discontinuous reception command, the discontinuous reception cycle that is entered correspondingly is the discontinuous reception cycle corresponding to the G-RNTI. For example, when a receiving end d receives a multicast service C and a multicast service D, the receiving end d receives the G-RNTI sent from the transmitting end. C After receiving the discontinuous reception command corresponding to service C, for service C, the discontinuous reception cycle corresponding to service C is used, and the G-RNTI corresponding to service C is CThe receiving end d receives the data of service C with the discontinuous reception setting parameters corresponding to D When an intermittent reception command corresponding to service D is received, the G-RNTI corresponding to service D is D and G-RNTI corresponding to service D. D The receiving end receives data for service D with the discontinuous reception setting parameters corresponding to G-RNTI. Therefore, for each G-RNTI, the present application collectively refers to all setting parameters for controlling the discontinuous reception operation of the multicast service corresponding to that G-RNTI as the discontinuous reception setting for multicast, and the receiving end using the discontinuous reception cycle corresponding to the G-RNTI (using the discontinuous reception cycle corresponding to the G-RNTI) and receiving data corresponding to the G-RNTI with the discontinuous reception setting corresponding to the G-RNTI both mean that the receiving end receives the service of G-RNTI with the setting parameters in the discontinuous reception setting for multicast corresponding to the G-RNTI. It should be noted that the terms "discontinuous reception mode," "discontinuous reception mode for multicast," "discontinuous reception setting," "discontinuous reception setting for multicast," etc. have the same meaning and can be interchanged.

[0046] The present application provides a method for transmitting an discontinuous reception command, in which a transmitting end configures a corresponding multicast-targeted discontinuous reception setting for a G-RNTI before transmitting the discontinuous reception command.

[0047] In an embodiment of the present invention, before the transmitting end sends the discontinuous reception command, the transmitting end configures a corresponding multicast target discontinuous reception configuration for G-RNTI, where the multicast target discontinuous reception configuration includes any of the following parameters: multicast target active period timer, multicast target continuous active period timer, multicast target discontinuous reception long cycle, multicast target discontinuous reception long cycle start subframe, and multicast target discontinuous reception long cycle start timeslot, in other words, before sending the discontinuous reception command, the transmitting end can further configure at least one of the corresponding parameters for G-RNTI in any order.

[0048] In another embodiment of the present invention, the transmitting end may set at least one of the following parameters for the G-RNTI in any order: active period timer for multicast; continuous active period timer for multicast; discontinuous reception long cycle for multicast; discontinuous reception long cycle start subframe for multicast; discontinuous reception long cycle start timeslot for multicast; discontinuous reception short cycle for multicast; and discontinuous reception short cycle counter for multicast.

[0049] The present application further provides a method for receiving an discontinuous reception command, in which a receiving end receives a discontinuous reception setting for a configured multicast corresponding to the G-RNTI before receiving the discontinuous reception command.

[0050] Specifically, before sending a DRX command corresponding to the G-RNTI, the transmitting end further sets a discontinuous reception setting for multicast corresponding to the G-RNTI, so that the receiving end uses the discontinuous reception cycle corresponding to the G-RNTI after receiving the discontinuous reception command, and receives the multicast service corresponding to the G-RNTI in the discontinuous reception cycle with the discontinuous reception setting for multicast corresponding to the G-RNTI.

[0051] In an embodiment of the present invention, before the receiving end receives the discontinuous reception command, the receiving end sets a discontinuous reception setting for multicast corresponding to the G-RNTI, and the discontinuous reception setting for multicast includes any parameters of an active period timer for multicast, a continuous active period timer for multicast, a discontinuous reception long cycle for multicast, a discontinuous reception long cycle start subframe for multicast, and a discontinuous reception long cycle start time slot for multicast. In other words, before receiving the discontinuous reception command, the receiving end can further set at least any of the above parameters corresponding to the G-RNTI in any order.

[0052] In another embodiment of the present invention, the receiving end may set at least one of the following parameters, in any order, corresponding to the G-RNTI: an active period timer for multicast, a continuous active period timer for multicast, a discontinuous reception long cycle for multicast, a discontinuous reception long cycle start subframe for multicast, a discontinuous reception long cycle start time slot for multicast, a discontinuous reception short cycle for multicast, and a discontinuous reception short cycle counter for multicast.

[0053] The parameters set in the discontinuous reception configuration for multicast described in this application include an active period timer for multicast.

[0054] The multicast active period timer here is used to represent the duration monitoring time at the start of the discontinuous reception cycle, i.e., the length of the multicast active period. Correspondingly, the transmitting end can configure the corresponding multicast active period timer for the receiving end to time based on the length of the corresponding multicast active period so as to monitor the PDCCH and receive DCI during the active period. The names "length of the multicast active period" and "multicast active period timer" may be expressed as "drx-onDurationTimer" or "drx-onDurationTimerPTM", or other names such as "drx-PTMonDurationTimer", where PTM stands for point to multipoint. The "duration monitoring time" may also be referred to as "duration reception time" or "duration." The terms "discontinuous reception cycle," "discontinuous reception cycle for multicast," "long discontinuous reception cycle," "long discontinuous reception cycle," and "long discontinuous reception cycle for multicast" have the same meaning and are interchangeable. Therefore, when the active period timer for multicast is used to represent the duration monitoring time at the start of the discontinuous reception cycle, it may be described as "drx-onDurationTimerP™ is set as the duration at the start of the discontinuous reception cycle." The present application does not limit this. Also, when the receiving end monitors the PDCCH during the active period and receives DCI, it may be described as "when drx-onDurationTimerP™ is running, the receiving end monitors the PDCCH and receives DCI."

[0055] After the receiving end receives or transmits data instructed in a certain subframe, it is likely that it will continue to be instructed in the next few subframes. Therefore, in order to reduce the delay, the receiving end is configured to be continuously positioned in an active period after being instructed, i.e., to set a continuous active period and continuously monitor the PDCCH during the continuous active period.

[0056] The parameters set in the discontinuous reception configuration for multicast described in this specification include a continuous active period timer for multicast.

[0057] The continuous active period timer for multicast here is used to represent the continuous monitoring time after the PDCCH is monitored at the receiving end, i.e., the length of the continuous active period for multicast, and correspondingly, for the receiving end, a corresponding continuous active period timer for multicast is configured to count based on the length of the continuous active period for multicast so that the receiving end continues to monitor the PDCCH and receive DCI during the continuous active period. The names "length of continuous active period for multicast" and "continuous active period timer for multicast" may be expressed as "drx-InactivityTimer", "drx-InactivityTimerPTM", or other names, such as "drx-PTMInactivityTimer", and the present application is not limited thereto. When the continuous active period timer for multicast is used to represent the continuous monitoring time after the PDCCH is monitored at the receiving end, it may be described that the drx-InactivityTimerPTM is set as the duration after the PDCCH is monitored at the receiving end. The receiving end continues to monitor the PDCCH and receive DCI during the continuous active period, which means that the receiving end continues to monitor the PDCCH and receive DCI while the continuous active period timer for multicast is running.

[0058] The parameters set in the discontinuous reception setting for multicast described in the present application may further include the length of the long discontinuous reception cycle for multicast. The "length of the long discontinuous reception cycle for multicast" and the "long discontinuous reception cycle for multicast" have the same meaning and are interchangeable.

[0059] The term "discontinuous reception long cycle for multicast" used herein is used to represent the total time length of the discontinuous reception long cycle for multicast that is activated by the receiving end. Correspondingly, the transmitting end may further configure a corresponding discontinuous reception long cycle timer for the receiving end to time based on the discontinuous reception long cycle for multicast, so that the receiving end monitors the PDCCH and receives DCI during the active period and continuous active period of the discontinuous reception long cycle for multicast. The names "discontinuous reception long cycle for multicast", "discontinuous reception long cycle timer for multicast", etc. may be expressed as "drx-LongDRXCycle-PTM", "drx-LongCycle-PTM", or other names such as "drx-PTMLongDRXCycle", "drx-DRXCycle", "drx-DRXCyclePTM", etc., and the present application does not limit this. The fact that the multicast discontinuous reception long cycle is used to represent the total time length of the discontinuous reception long cycles for multicast initiated by the receiving end may be described as drx-LongCycle-PTM being set to represent the total time length of the long DRX cycles used by the receiving end.

[0060] The parameters set in the discontinuous reception configuration for multicast described in the present application may further include a discontinuous reception long cycle start subframe for multicast.

[0061] The discontinuous reception long cycle start subframe for multicast is used to indicate that the receiving end will use the discontinuous reception long cycle for multicast from the subframe, and the discontinuous reception long cycle start subframe for multicast is usually represented by "drx-LongCycleStartOffsetPTM", but may be represented by other names such as "drx-LongCycleStartOffset", "drx-PTMLongCycleStartOffset", etc., and this application does not limit this. The use of the discontinuous reception long cycle start subframe for multicast to indicate that the receiving end will enter the discontinuous reception long cycle for multicast from the subframe may be described as "drx-LongCycleStartOffsetPTM is set to indicate that the receiving end will use the long DRX cycle from the drx-LongCycleStartOffsetPTM", or "drx-StartOffsetPTM is set to indicate that the receiving end will use the long DRX cycle from the drx-StartOffsetPTM". "drx-LongCycleStartOffsetPTM" and "drx-StartOffsetPTM" have the same meaning and can be substituted for each other.

[0062] The parameters set in the discontinuous reception setting for multicast described in the present application may further include a discontinuous reception long cycle start time slot for multicast.

[0063] The discontinuous reception long cycle start timeslot for multicast is used to instruct a receiving end to use a discontinuous reception long cycle for multicast from the start timeslot in the start subframe, and is usually represented by "drx-SlotOffsetPTM", but may be represented by other names, such as "drx-PTMSlotOffset", "drx-SlotOffset", etc., and this application does not limit this. The use of the discontinuous reception long cycle start timeslot for multicast to instruct a receiving end to enter a discontinuous reception long cycle for multicast from the start timeslot in the start subframe may be described as drx-SlotOffsetPTM being set to instruct a receiving end to enter a long DRX cycle from the drx-SlotOffsetPTM in the drx-StartOffsetPTM.

[0064] The parameters set in the discontinuous reception setting for multicast described in the present application may further include a discontinuous reception short cycle for multicast.

[0065] The multicast target discontinuous reception short cycle here is used to represent the total length of the multicast target discontinuous reception short cycle entered / activated by the receiving end. Correspondingly, the receiving end further sets a corresponding multicast target discontinuous reception short cycle so as to monitor the PDCCH and receive DCI during the active period and continuous active period of the multicast target discontinuous reception short cycle, and sets the multicast target discontinuous reception short cycle timer to time based on the multicast target discontinuous reception short cycle. The name "multicast target discontinuous reception short cycle timer" may be expressed as "drx-shortDRXCycle", "drx-shortDRXCyclePTM", or other names, such as "drx-PTMshortDRXCycle". The name "multicast target discontinuous reception short cycle", "discontinuous reception short cycle", etc. may be expressed as "drx-shortcyclePTM". This application does not limit this.

[0066] The parameters set in the discontinuous reception setting for multicast described in the present application may further include a discontinuous reception short cycle counter for multicast.

[0067] The multicast discontinuous reception short cycle counter here is used to indicate the total number of multicast discontinuous reception short cycles that the receiving end can enter consecutively. Correspondingly, the total number of multicast discontinuous reception short cycles may be further set in the receiving end, and the receiving end uses the multicast discontinuous reception short cycle and starts the multicast discontinuous reception short cycle counter to count the total number of multicast discontinuous reception short cycles, thereby controlling the receiving end to receive services in consecutive multicast discontinuous reception short cycles. In other words, the multicast discontinuous reception short cycle at this time can also be considered as the length of the total cycle of the multicast discontinuous reception short cycles corresponding to the number. For example, if the number of intermittent reception short cycles for multicast is 2, after the receiving end finishes one intermittent reception short cycle for multicast, it can continue to receive services, etc. using a second intermittent reception short cycle for multicast. The "intermittent reception cycle counter for multicast" may usually be expressed as "drx-ShortCycleTimer" or "drx-ShortCycleTimerPTM", or may be expressed using other names, such as "drx-PTMShortCycleTimer" or "drx-ShortDRXCycleTimer", and this application does not restrict this.

[0068] In addition, the set long discontinuous reception cycle for multicast may be the same as or different from the length of the active period and the length of the continuous active period in the set short discontinuous reception cycle for multicast. That is, when the length of the short cycle active period and the length of the continuous active period are the same as the length of the long cycle active period and the length of the continuous active period, the receiving end monitors the PDCCH with the initially set active period length and / or the length of the continuous active period, and when the DRX command received at the receiving end instructs the receiving end to use the long cycle or the short cycle, the receiving end receives the corresponding service with the same active period length or the length of the continuous active period. When the length of the short cycle active period and the length of the continuous active period are different from the length of the long cycle active period and the length of the continuous active period, the transmitting end The active period length, the short cycle active period length, the short cycle continuous active period length, the long cycle active period length, and the long cycle continuous active period length are set in the DRX command, and the receiving end monitors the PDCCH with the active period length and / or the continuous active period length accordingly, and receives services with the short cycle active period length and / or the short cycle continuous active period length if the DRX command received at the receiving end instructs the receiving end to use a short cycle, while receiving services with the long cycle active period length and / or the long cycle continuous active period length if the DRX command instructs the receiving end to use a long cycle.

[0069] In some special cases, if the transmitting end finds that the preset discontinuous reception setting for multicast does not meet the current service needs, it can adjust the current discontinuous reception setting for multicast, for example, by re-assigning values to the parameters of the discontinuous reception setting for multicast and re-setting the setting with the adjusted discontinuous reception setting for multicast. That is, after receiving each discontinuous reception command, the receiving end always uses the discontinuous reception cycle for multicast based on the corresponding preset discontinuous reception setting for multicast. The transmitting end sets the discontinuous reception setting for multicast corresponding to G-RNTI only once, and then transmits discontinuous reception commands as needed based on the status of the service corresponding to G-RNTI at the current time and at a future time and the status of the receiving end receiving the service. After receiving the discontinuous reception command corresponding to G-RNTI, the receiving end uses the discontinuous reception cycle for multicast based on the parameters set in the previously received discontinuous reception setting for multicast and performs operations with the parameters set in the discontinuous reception setting for multicast.

[0070] That is, the transmitting end mentioned below sets the discontinuous reception setting DRX configuration0 for multicast corresponding to G-RNTI0 in advance at the receiving end (i.e., sets one set of parameters corresponding to G-RNTI0 and used for discontinuous reception), and after receiving the discontinuous reception command, the receiving end uses the discontinuous reception cycle in the discontinuous reception setting for multicast corresponding to G-RNTI (i.e., operates with the set "parameter value of the discontinuous reception cycle corresponding to G-RNTI0"), runs the discontinuous reception long cycle timer for multicast in the discontinuous reception setting for multicast corresponding to G-RNTI (i.e., times with the set parameter value of "drx-LongCycle-PTM corresponding to G-RNTI0"), and The drx-onDurationTimerPTM with the intermittent reception setting for the multicast corresponding to G-RNTI0 is started (i.e., it starts timing using the parameter value of the set "intermittent reception short-cycle timer for the multicast corresponding to G-RNTI0"), the drx-onDurationTimerPTM with the intermittent reception setting for the multicast corresponding to G-RNTI0 is started (i.e., it starts timing using the parameter value of the set "drx-onDurationTimerPTM corresponding to G-RNTI0"), and the drx-InactivityTimerPTM with the intermittent reception setting for the multicast corresponding to G-RNTI0 is started (i.e., it starts timing using the parameter value of the set "drx-InactivityTimerPTM corresponding to G-RNTI0").

[0071] The short discontinuous reception cycle is merely a transitional state between continuous reception and a long discontinuous reception cycle. That is, it enters an active period after a short sleep period. On the other hand, if the receiving end has not received data after several short cycles, this indicates that the service is sparse at this time and for a certain period in the future, and the long discontinuous reception cycle can be used. That is, the active period cannot be entered until a long sleep period has passed. Accordingly, in this application, the purpose of sending the discontinuous reception command from the transmitting end is to cause the receiving end to use the discontinuous reception cycle after receiving the discontinuous reception command. Whether to instruct the receiving end to use the long discontinuous reception cycle for multicast or the short discontinuous reception cycle for multicast involves selecting a balance between saving power and delaying data reception. On the one hand, controlling the receiving end to use the long discontinuous reception cycle for multicast means that the receiving end will be in sleep mode for a longer period, which is beneficial to extending the battery life of the receiving end. On the other hand, controlling the receiving end to use the short discontinuous reception cycle for multicast when new data is being transmitted is beneficial to the receiving end's fast response.Therefore, the present application provides two types of discontinuous reception commands to distinguish between a transmitting end sending different discontinuous reception commands to cause a receiving end to use different discontinuous reception cycles, i.e., a short discontinuous reception cycle for multicast or a long discontinuous reception cycle for multicast. The discontinuous reception commands include a first command and a second command, the first command is a discontinuous reception command for multicast, and the second command is a long discontinuous reception command for multicast. When the discontinuous reception command received by the receiving end is a command from the transmitting end to instruct the receiving end to use the long discontinuous reception cycle, the discontinuous reception command is essentially a long discontinuous reception command for multicast. and if the discontinuous reception command received at the receiving end is a discontinuous reception command from the transmitting end instructing the receiving end to use a short discontinuous reception cycle, then the discontinuous reception command is essentially a multicast-targeted discontinuous reception command, where "long" is relative, that is, the "long discontinuous reception command for multicast" of the present invention may be called an "intermittent reception command for multicast", and the "discontinuous reception command for multicast" of the present invention may be called a "short discontinuous reception command for multicast". In practice, the wording of the command names does not change the essence of the operation targeted by the command, and the present application does not limit the wording of the command names. The "DRX command" and the "multicast-targeted DRX command" of the present invention have the same meaning and are interchangeable.

[0072] The present application provides a method for discontinuous reception of data, in which the receiving end can use the drx-LongCycle-PTM corresponding to the G-RNTI for the service corresponding to the G-RNTI after receiving a discontinuous reception command.

[0073] Specifically, when one or more multicast broadcast services become very sparse, the transmitting end can send an discontinuous reception command (the discontinuous reception command here means instructing the receiving end to use a long discontinuous reception command for multicast with a long discontinuous reception cycle for the multicast service), and accordingly, after receiving the discontinuous reception command, the receiving end will use the long discontinuous reception cycle for multicast to receive the service in the active period of the long discontinuous reception cycle for multicast, regardless of whether a short discontinuous reception cycle for multicast is set in the discontinuous reception setting for multicast corresponding to the pre-set G-RNTI (i.e., regardless of whether the parameter of the "short discontinuous reception cycle for multicast" corresponding to the G-RNTI is pre-set).

[0074] It should be noted that the use of the discontinuous reception long cycle for the multicast corresponding to the G-RNTI described in this application means using the parameters of the discontinuous reception long cycle for the multicast corresponding to the set G-RNTI, which essentially means using the discontinuous reception long cycle for the multicast corresponding to the G-RNTI.

[0075] The present application further provides a method for receiving an discontinuous reception command, in which after a receiving end receives an discontinuous reception command, it determines whether a drx-onDurationTimerPTM corresponding to a G-RNTI is running, and if YES, stops the drx-onDurationTimerPTM.

[0076] The essence of the operation here is to stop drx-onDurationTimerPTM, and determining whether it is currently running or not is merely to ensure the correct execution of the receiving method. It should be noted that drx-onDurationTimerPTM may also be stopped directly without determining whether it is currently running or not.

[0077] The present application further provides a method for receiving an intermittent reception command, in which after a receiving end receives an intermittent reception command, it can determine whether a drx-InactivityTimerPTM is operating in an intermittent reception setting for multicast corresponding to a G-RNTI, and if YES, stops the drx-InactivityTimerPTM.

[0078] The essence of the operation here is to stop the drx-InactivityTimerPTM, and determining whether it is currently running or not is merely to ensure the correct execution of the receiving method. It should be noted that it is also possible to stop the drx-InactivityTimerPTM directly without determining whether it is currently running or not.

[0079] The present application further provides a method for receiving an intermittent reception command, in which after a receiving end receives an intermittent reception command, it determines whether an intermittent reception short cycle counter for multicast corresponding to G-RNTI is operating, and if YES, stops the intermittent reception short cycle counter for the multicast.

[0080] The essence of the operation here is to stop the intermittent reception short cycle counter for multicast, and determining whether it is currently operating or not is merely to ensure the correct execution of the receiving method. It should be noted that the intermittent reception short cycle counter for multicast may be directly stopped without determining whether it is currently operating or not.

[0081] For example, in the communication system, both user equipment b and user equipment c are receiving service B, and service B is in a very sparse transmission state. The transmitting end pre-configures the receiving ends b and c with a multicast DRX configuration 2 corresponding to G-RNTI2 of service B (i.e., configures a set of parameters corresponding to G-RNTI2 and used for discontinuous reception), and then sends a discontinuous reception command to service B. Upon receiving the discontinuous reception command, the receiving ends b and c use the multicast DRX long cycle in the multicast DRX configuration corresponding to G-RNTI2, run the multicast DRX long cycle timer corresponding to G-RNTI2, and stop the operation of the drx-onDurationTimerPTM and drx-InactivityTimerPTM corresponding to G-RNTI2.

[0082] In addition, the discontinuous reception cycle entered for the service corresponding to the G-RNTI of the present application, and the timer and counter in the operating discontinuous reception cycle all have a corresponding relationship with each other.

[0083] In the present application, when an discontinuous reception command is received at the receiving end and a discontinuous reception short cycle for multicast corresponding to the G-RNTI has already been set, Provided is a method for receiving an intermittent reception command that enables a receiving end to use an intermittent reception short cycle for multicast in an intermittent reception setting for multicast corresponding to the G-RNTI for a service corresponding to the G-RNTI.

[0084] Specifically, when one or more multicast broadcast services become sparse, the transmitting end can send an intermittent reception command (the intermittent reception command here is to instruct the user equipment to use the multicast-targeted intermittent reception command with an intermittent reception short cycle for the multicast service) and accordingly, after receiving the intermittent reception command, the receiving end will preferentially use the multicast-targeted intermittent reception short cycle based on the set multicast-targeted intermittent reception setting, and receive the service in the corresponding multicast-targeted intermittent reception mode. For example, in a communication system having service A and user equipment a, user equipment b, and user equipment c receiving service A, when the transmitting end discovers that service A has become sparse, it transmits an discontinuous reception command, and after receiving the discontinuous reception command, the receiving ends a, b, and c use the short discontinuous reception cycle for multicast corresponding to the G-RNTI corresponding to service A for service A, turn on the corresponding receiving circuit to receive service A during the active period for multicast or the continuous active period for multicast of the short discontinuous reception cycle for multicast, and turn off the corresponding receiving circuit to not perform a receiving operation during the sleep period of the short discontinuous reception cycle for multicast.

[0085] In the present application, when an intermittent reception command is received at the receiving end and an intermittent reception short cycle for multicast corresponding to the G-RNTI has already been set, The receiving end provides a method for receiving an intermittent reception command, which can start an intermittent reception short cycle counter for a multicast corresponding to the G-RNTI for a service corresponding to the G-RNTI.

[0086] Specifically, when one or more multicast broadcast services become sparse, the transmitting end can send an DREC command (the DREC command here is to instruct the user equipment to use a DREC command for multicast targeted at a short DREC cycle for the multicast service), and accordingly, after receiving the DREC command, the receiving end receives the service at a continuous DREC short cycle for multicast targeted at a short DREC cycle according to the DREC counter for multicast targeted at a short DREC cycle in the DREC setting for multicast. For example, in a communication system having service A and user equipment a, user equipment b, and user equipment c receiving service A, when the transmitting end finds that service A has become sparse, it transmits a multicast-targeted discontinuous reception command, and after receiving the discontinuous reception command, the receiving ends a, b, and c use the first corresponding multicast-targeted discontinuous reception short cycle for service A if the number of multicast-targeted discontinuous reception short cycles in the pre-configured multicast-targeted discontinuous reception setting corresponding to the G-RNTI corresponding to service A is 2, and after the first multicast-targeted discontinuous reception short cycle is finished, continue to use the second multicast-targeted discontinuous reception short cycle. The present application provides a method for receiving an discontinuous reception command, in which the receiving end starts a multicast-targeted discontinuous reception short cycle counter corresponding to the G-RNTI at the first symbol after receiving the discontinuous reception command.

[0087] In other words, when the receiving end receives an intermittent reception command (here, the intermittent reception command instructs the user equipment to use an intermittent reception command for multicast with an intermittent reception short cycle for the multicast service), it starts the intermittent reception short cycle counter for multicast corresponding to the G-RNTI at the first symbol after receiving the intermittent reception command, thereby using one or more intermittent reception short cycles for multicast indicated by the count value of the intermittent reception short cycle counter for multicast.

[0088] In the present application, an intermittent reception short cycle for multicast corresponding to the G-RNTI has already been set at the receiving end, and an intermittent reception command is received. The receiving end, for the service corresponding to the G-RNTI, Using a short discontinuous reception cycle for multicast corresponding to the G-RNTI, A method for receiving an intermittent reception command that starts an intermittent reception short cycle counter for multicast corresponding to the G-RNTI is provided.

[0089] In this application, the discontinuous reception cycle entered for the service corresponding to the G-RNTI, the timer and counter in the running discontinuous reception cycle all have a corresponding relationship with each other.

[0090] For example, assume that user equipment a and user equipment b in a communication system are both receiving service A, and service A is in a sparse state. The transmitting end pre-configures the receiving ends a and b with a discontinuous reception setting DRX configuration 1 for multicast corresponding to G-RNTI1, which corresponds to service A (i.e., configures one set of parameters corresponding to G-RNTI1 and used for discontinuous reception, in the receiving ends), and then transmits a discontinuous reception command for service A. Upon receiving the discontinuous reception command, the receiving ends a and b use the discontinuous reception short cycle for multicast in the discontinuous reception setting multicast DRX configuration 1 for multicast corresponding to G-RNTI1, and start the discontinuous reception short cycle timer for multicast and the discontinuous reception short cycle counter for G-RNTI1.

[0091] In the present application, an intermittent reception command is received at the receiving end, but an intermittent reception short cycle for multicast corresponding to the G-RNTI is not set, For the service corresponding to the G-RNTI, a receiving end is provided with a method for receiving an intermittent reception command, which allows the receiving end to use an intermittent reception long cycle for multicast corresponding to the G-RNTI.

[0092] Specifically, when a receiving end receives an intermittent reception command (here, the intermittent reception command instructs the receiving end to use an intermittent reception command targeted at multicast with an intermittent reception short cycle for a multicast service), if the intermittent reception setting targeted at multicast corresponding to the G-RNTI being received by the receiving end does not include an intermittent reception short cycle targeted at multicast (i.e., if the parameter for "intermittent reception short cycle targeted at multicast" corresponding to the G-RNTI is not set at the receiving end), the intermittent reception long cycle targeted at multicast in the intermittent reception setting targeted at multicast corresponding to the G-RNTI is used for the service corresponding to the G-RNTI.

[0093] This application is When the receiving end receives an discontinuous reception command and the discontinuous reception short cycle for the multicast corresponding to the G-RNTI has already been set, the receiving end shall, for the service corresponding to the G-RNTI: Using a short discontinuous reception cycle for multicast corresponding to the G-RNTI, activating an intermittent reception short cycle counter for multicast corresponding to the G-RNTI; When the receiving end receives an discontinuous reception command but the discontinuous reception short cycle for the multicast corresponding to the G-RNTI is not set, the receiving end shall, for the service corresponding to the G-RNTI: and using a long discontinuous reception cycle for multicast corresponding to the G-RNTI.

[0094] The present application provides a method for receiving an intermittent reception command that is 0 bits in length.

[0095] Specifically, the length of the discontinuous reception command is 0 bits, that is, the discontinuous reception command does not include any G-RNTI or any information.

[0096] The discontinuous reception command in this application is a MAC layer message, and the MAC layer message here refers to a MAC CE (MAC Control Element, a control element of the multi-access control layer), where the MAC CE has a corresponding MAC subheader, and the MAC CE and the MAC subheader together constitute a MAC subPDU. The length of the discontinuous reception command is 0 bits, which means that the length of the MAC CE is 0 bits.

[0097] If the MAC subheader includes R and LCID (Logical Channel ID), the MAC CE is a fixed-sized MAC CE, and if the MAC subheader includes R, F, LCID, and L, the MAC CE is a variable-sized MAC CE, and the MAC subheader also includes other structures, which are not listed here. Accordingly, in order to enable the receiving end to obtain the received MAC layer message as a discontinuous reception command and further achieve the purpose of receiving multicast services in a discontinuous reception manner, the present application can use the LCID in the MAC subheader to indicate the type of the corresponding MAC CE as a discontinuous reception command, and a specific indication process may be as follows:

[0098] The present application provides a method for receiving an intermittent reception command, in which an LCID is included in a MAC subheader and the LCID can be used to indicate a corresponding MAC CE as an intermittent reception command (unicast intermittent reception command or unicast long intermittent reception command).

[0099] The PDCCH addressed by the G-RNTI is monitored at the receiving end, and the value of the LCID received by the receiving end indicates the type of the corresponding MAC CE as an discontinuous reception command (the discontinuous reception command is a unicast discontinuous reception command or a unicast long discontinuous reception command), and at this time, regardless of whether the corresponding MAC CE includes a G-RNTI (this G-RNTI is not limited to being the same as other G-RNTIs in this paragraph, such as the G-RNTI for addressing the PDCCH), that is, whether the MAC CE is 0 bit or includes at least one G-RNTI, the service corresponding to the G-RNTI for addressing the PDCCH will enter the discontinuous reception cycle corresponding to the G-RNTI (the discontinuous reception cycle is a short discontinuous reception cycle for multicast or a long discontinuous reception cycle for multicast).

[0100] When the PDCCH addressed by the C-RNTI is monitored at the receiving end, and the LCID received by the receiving end indicates the corresponding MAC CE as a unicast discontinuous reception command or a unicast long discontinuous reception command, further analysis leads to the following: If the MAC CE does not include the G-RNTI, the receiving end uses the existing unicast discontinuous reception short cycle or unicast discontinuous reception long cycle for the unicast service being received.

[0101] Specifically, referring to the assigned values of LCID in 3GPP TS 38.321, a first type of LCID assigned value table is provided. As shown in Table 1 below, if the LCID takes a value of 59, the corresponding MAC CE is indicated as a unicast long discontinuous reception command; if the LCID takes a value of 60, the corresponding MAC CE is indicated as a unicast discontinuous reception command; thus, the receiving end monitors the PDCCH addressed by the C-RNTI. If the LCID received by the receiving end takes a value of 59 and the MAC CE does not include G-RNTI, the receiving end uses the existing unicast discontinuous reception long cycle for the received unicast service; if the PDCCH addressed by the C-RNTI is monitored by the receiving end, the LCID received by the receiving end takes a value of 60 and the MAC CE does not include G-RNTI, the receiving end uses the existing unicast discontinuous reception short cycle for the received unicast service.

[0102] [Table 1] Table 1. Type 1 LCID allocation value table

[0103] If the MAC CE includes one G-RNTI, the receiving end uses the short discontinuous reception cycle for multicast corresponding to the G-RNTI or the long discontinuous reception cycle for multicast corresponding to the G-RNTI only for the service corresponding to the G-RNTI. Correspondingly, if the MAC CE further includes one Session ID or TMGI, the receiving end uses the long discontinuous reception cycle for multicast corresponding to the Session ID or TMGI. The operation of including the Session ID or TMGI is the same as the operation of including the G-RNTI, and will not be repeated. If the MAC CE includes multiple G-RNTIs, the receiving end may further use a multicast-targeted DNR short cycle or a multicast-targeted DNR long cycle for each of the multiple services corresponding to the multiple G-RNTIs received by the receiving end. For each G-RNTI included in the MAC CE, the receiving end may sequentially determine whether the receiving end is in a user equipment group corresponding to the G-RNTI, that is, whether the receiving end receives the service corresponding to the G-RNTI. If the result is NO, the G-RNTI may be ignored and no operation may be performed. If the result is YES, the receiving end may use a multicast-targeted DNR short cycle or a multicast-targeted DNR long cycle for the service of the G-RNTI. Correspondingly, the MAC CE may further include multiple Session IDs or TMGIs, and may use a multicast-targeted DNR long cycle corresponding to the Session IDs or TMGIs. The operation involving a Session ID or TMGI is the same as the operation involving a G-RNTI, and therefore will not be described again.

[0104] Furthermore, in this embodiment, not only can the receiving end achieve the purpose of using a multicast-targeted intermittent receiving cycle for multicast services, but also it can avoid changing or adjusting the existing communication protocol and avoid increasing the complexity of the communication system.

[0105] The present application provides a method for receiving an intermittent reception command, in which an LCID (Logical Channel ID) is included in a MAC subheader, and the LCID can be used to indicate a corresponding MAC CE as an intermittent reception command (common intermittent reception command or common long intermittent reception command).

[0106] It should be noted that the common intermittent reception command here is merely for instructing the receiving end to receive the service in an intermittent reception manner using an intermittent reception cycle, and is not limited to instructing the receiving end to use a unicast intermittent reception cycle for a unicast service, or to instructing the receiving end to use an intermittent reception cycle targeted at multicast for a multicast service.

[0107] In this application, a common discontinuous reception configuration is pre-configured for all services received by a receiving end corresponding to a C-RNTI. In this application, all services include multiple unicast services and multiple multicast services. The multiple unicast services share a set of configuration parameters, including drx-onDurationTimer, drx-InactivityTimer, drx-LongCycle, drx-LongCycleStartOffset, drx-SlotOffset, drx-shortcycle, and drx-ShortCycleTimer. A G-RNTI corresponding to each multicast service corresponds to a set of parameters, namely, drx-onDurationTimerPTM corresponding to the G-RNTI, drx-InactivityTimerPTM corresponding to the G-RNTI, drx-LongCycle-PTM corresponding to the G-RNTI, drx-LongCycleStartOffset-PTM corresponding to the G-RNTI, and drx-SlotOffsetPTM corresponding to the G-RNTI.

[0108] The receiving end monitors the PDCCH addressed by the G-RNTI, and indicates the corresponding MAC CE with the LCID received by the receiving end as a common discontinuous reception command or a common long discontinuous reception command. For the service corresponding to the G-RNTI, the receiving end performs at least one of the following operations: activate drx-LongCycle-PTM for the G-RNTI, and / or stop drx-onDurationTimerPTM for the G-RNTI, and / or stop drx-InactivityTimerPTM for the G-RNTI. Note that in this application, the common discontinuous reception command is used to control discontinuous reception operation of unicast services and / or discontinuous reception operation of multicast services, and the type of service to which the discontinuous reception command is applied is limited by different scrambling schemes. Therefore, the common discontinuous reception command may be called a discontinuous reception command when controlling a unicast service, and may be called a discontinuous reception command when controlling a multicast service. The common discontinuous reception command may be expressed as "Common DRX command MAC CE" or "DRX command MAC CE", and this patent is not limited thereto.

[0109] When the PDCCH addressed by the C-RNTI is monitored by the receiving end, and the LCID received by the receiving end indicates the corresponding MAC CE as a common discontinuous reception command or a common long discontinuous reception command, the receiving end uses the long discontinuous reception cycle for all received unicast services or enters the short discontinuous reception cycle. For unicast services, if the MAC CE is the common discontinuous reception command and the discontinuous reception setting for a set of unicast services shared by the receiving end corresponding to the C-RNTI has already been configured and the short discontinuous reception cycle is set in the discontinuous reception setting, the receiving end uses the short discontinuous reception cycle corresponding to the discontinuous reception setting of the unicast service; otherwise, the receiving end uses the long discontinuous reception cycle corresponding to the discontinuous reception setting of the unicast service. The principle of the common long discontinuous reception command is similar and will not be repeated here. Further analysis leads to the following: If the MAC CE does not include G-RNTI, the receiving end uses a common discontinuous reception short cycle or a common discontinuous reception long cycle for all the services it is receiving. In addition, if the receiving end uses a discontinuous reception short cycle for all the services it is receiving, if a discontinuous reception setting for multicast corresponding to the G-RNTI has already been configured for the service corresponding to each G-RNTI, it uses a discontinuous reception short cycle for multicast corresponding to the discontinuous reception setting for multicast, and if a discontinuous reception setting for multicast corresponding to the G-RNTI has not been configured, it uses a common discontinuous reception short cycle for multicast corresponding to the common discontinuous reception setting or a common discontinuous reception short cycle corresponding to the common discontinuous reception setting. On the other hand, for a unicast service, if a discontinuous reception setting for the unicast service has already been configured for the receiving end corresponding to the C-RNTI, it uses a discontinuous reception short cycle corresponding to the discontinuous reception setting for the unicast service, and if a discontinuous reception setting for the unicast service has not been configured for the receiving end corresponding to the C-RNTI, it uses a common discontinuous reception short cycle corresponding to the common discontinuous reception setting. The long period is similar and will not be repeated here.

[0110] In one preferred embodiment, the values of LCID are as shown in Table 2 below. For example, if the LCID takes a value of 64, the corresponding MAC CE is indicated as a common long discontinuous reception command; if the LCID takes a value of 65, the corresponding MAC CE is indicated as a common discontinuous reception command. Thus, when the PDCCH addressed by the C-RNTI is monitored at the receiving end, if the LCID received by the receiving end takes a value of 64, the receiving end uses a common long discontinuous reception cycle for all the unicast services being received; when the PDCCH addressed by the C-RNTI is monitored at the receiving end and the LCID received by the receiving end takes a value of 65, the receiving end uses a common short discontinuous reception cycle for all the unicast services being received. When the PDCCH addressed by the G-RNTI is monitored at the receiving end, if the LCID received by the receiving end takes a value of 64 or 65, the receiving end uses a discontinuous reception cycle corresponding to the G-RNTI for the multicast service corresponding to the received G-RNTI. It should be noted that the possible values of LCID here are merely enumerated, and that in practice, when the possible value of LCID is 59, the LCID may be used to indicate that the corresponding MAC CE is a common long discontinuous reception command, and when the possible value of LCID is 60, the LCID may be used to indicate that the corresponding MAC CE is a common discontinuous reception command.

[0111] [Table 2] Table 2: Type 2 LCID Assignment Value Table

[0112] The present application provides a method for receiving an intermittent reception command, in which an LCID is included in a MAC subheader and the LCID can be used to indicate the corresponding MAC CE as an intermittent reception command (an intermittent reception command intended for multicast or a long intermittent reception command intended for multicast).

[0113] In addition, the present application has already pre-configured common discontinuous reception settings for multicast for all multicast services received by the receiving end corresponding to C-RNTI, and the common discontinuous reception settings for multicast include a common active period timer for multicast, a common continuous active period timer for multicast, a common discontinuous reception long cycle for multicast, a common discontinuous reception long cycle start subframe for multicast, a common discontinuous reception long cycle start time slot for multicast, a common discontinuous reception short cycle for multicast, and a common discontinuous reception short cycle counter for multicast.

[0114] When a PDCCH addressed by the G-RNTI is monitored at a receiving end, and the LCID received by the receiving end indicates the corresponding MAC CE as a multicast-targeted discontinuous reception command or a multicast-targeted long discontinuous reception command, regardless of whether the MAC CE includes the G-RNTI, the multicast-targeted short discontinuous reception cycle or the multicast-targeted long discontinuous reception cycle corresponding to the G-RNTI can still be used for the service corresponding to the G-RNTI. Note that, in this application, the MAC CE as the multicast-targeted discontinuous reception command may be referred to as "DRX command MAC CE for multicast," "DRX command for multicast," "PTM DRX command MAC CE," etc., or by other names, and the application is not limited thereto. Correspondingly, the MAC CE as the multicast-targeted long discontinuous reception command may be referred to as "Long DRX command MAC CE for multicast," "Long DRX command for multicast," "PTM Long DRX command MAC CE," etc., or by other names, and the application is not limited thereto.

[0115] When the PDCCH addressed by the C-RNTI is monitored at the receiving end, and the LCID received by the receiving end indicates the corresponding MAC CE as a DNR command for multicast or a LDR command for multicast, further analysis leads to the following: If the MAC CE does not include G-RNTI, the receiving end uses a multicast-targeted discontinuous reception short cycle or a multicast-targeted discontinuous reception long cycle for all the multicast services being received. Note that when a multicast-targeted discontinuous reception short cycle is used for all the multicast services being received by the receiving end, if a multicast-targeted discontinuous reception setting corresponding to the G-RNTI is set for the service corresponding to each G-RNTI, the multicast-targeted discontinuous reception short cycle corresponding to the multicast-targeted discontinuous reception setting is used, and if a multicast-targeted discontinuous reception setting corresponding to the G-RNTI is not set, the multicast-targeted common discontinuous reception short cycle corresponding to the multicast-targeted common discontinuous reception setting is used, and the long cycle is the same as that, so it will not be described again here.

[0116] In one preferred implementation, the value of LCID is as shown in Table 3 below. For example, if the value of LCID is 64, the corresponding MAC CE is indicated as a long discontinuous reception command for multicast; if the value of LCID is 65, the corresponding MAC CE is indicated as a discontinuous reception command for multicast. Thus, the receiving end monitors the PDCCH addressed by the C-RNTI. If the value of LCID received by the receiving end is 64 and the MAC CE does not include G-RNTI, the receiving end uses the long discontinuous reception cycle for multicast for all the received multicast services; if the value of PDCCH addressed by C-RNTI is 65 and the MAC CE does not include G-RNTI, the receiving end uses the short discontinuous reception cycle for multicast for all the received multicast services.

[0117] [Table 3] Table 3: Type 3 LCID Assignment Value Table

[0118] If one G-RNTI is included in the MAC CE, the receiving end uses the multicast-targeted discontinuous reception short cycle or multicast-targeted discontinuous reception long cycle corresponding to the G-RNTI only for the service corresponding to the G-RNTI. Correspondingly, if one Session ID or TMGI is further included in the MAC CE, the receiving end uses the multicast-targeted discontinuous reception short cycle or multicast-targeted discontinuous reception long cycle corresponding to the Session ID or TMGI. The operation of including a Session ID or TMGI is the same as the operation of including a G-RNTI, and will not be described again. If a MAC CE includes multiple G-RNTIs, the receiving end may further use a multicast-targeted DREC short cycle or a multicast-targeted DREC long cycle for each of a plurality of services corresponding to the plurality of G-RNTIs received by the receiving end. For each G-RNTI included in the MAC CE, the receiving end may sequentially determine whether the receiving end is in a user equipment group corresponding to the G-RNTI, that is, whether the receiving end receives a service corresponding to the G-RNTI. If the result is NO, the G-RNTI is ignored and no operation is performed. If the result is YES, the receiving end uses a multicast-targeted DREC short cycle or a multicast-targeted DREC long cycle corresponding to the G-RNTI for the service corresponding to the G-RNTI. Correspondingly, a plurality of Session IDs or TMGIs may also be included in the MAC CE, and the multicast-targeted DREC short cycle or the multicast-targeted DREC long cycle corresponding to the Session IDs or TMGIs is used. The operation involving a Session ID or TMGI is the same as the operation involving a G-RNTI, and will not be described again.

[0119] The present application provides a method for receiving an intermittent reception command, in which an LCID is included in a MAC subheader and the LCID can be used to indicate a corresponding MAC CE as an intermittent reception command (an intermittent reception command targeted at a multicast corresponding to a G-RNTI or a long intermittent reception command targeted at a multicast corresponding to a G-RNTI).

[0120] When a PDCCH addressed by the G-RNTI is monitored at the receiving end, and the LCID received by the receiving end indicates the corresponding MAC CE as an discontinuous reception command for multicast corresponding to the G-RNTI or a long discontinuous reception command for multicast corresponding to the G-RNTI, the short discontinuous reception cycle for multicast corresponding to the G-RNTI or the long discontinuous reception cycle for multicast corresponding to the G-RNTI can still be used for the service corresponding to the G-RNTI, regardless of whether the MAC CE includes the G-RNTI.

[0121] When the PDCCH addressed by the C-RNTI is monitored at the receiving end, and the LCID received by the receiving end indicates the corresponding MAC CE as a discontinuous reception command for multicast corresponding to the G-RNTI or a long discontinuous reception command for multicast corresponding to the G-RNTI, further analysis leads to the following: If the MAC CE does not include the G-RNTI, the receiving end uses the short discontinuous reception cycle for multicast or the long discontinuous reception cycle for multicast corresponding to the G-RNTI only for the service corresponding to the G-RNTI.

[0122] In one preferred implementation method, the values of LCID are as shown in Table 4 below. For example, if the LCID value is 64, the corresponding MAC CE is designated as a long discontinuous reception command for the multicast corresponding to G-RNTI1; if the LCID value is 65, the corresponding MAC CE is designated as a discontinuous reception command for the multicast corresponding to G-RNTI1; if the LCID value is 66, the corresponding MAC CE is designated as a long discontinuous reception command for the multicast corresponding to G-RNT2; if the LCID value is 67, the corresponding MAC CE is designated as a discontinuous reception command for the multicast corresponding to G-RNTI2; ..., if the LCID value is 63+2N-1, the corresponding MAC CE is designated as a long discontinuous reception command for the multicast corresponding to G-RNTI3; NIf the LCID value is 63+2N, the corresponding MAC CE is set as G-RNTI N When the receiving end monitors the PDCCH addressed by the C-RNTI, and the LCID received by the receiving end has a value of 64 and the MAC CE does not include G-RNTI, the receiving end uses the discontinuous reception long cycle for the multicast corresponding to G-RNTI1 for the multicast service corresponding to G-RNTI1 being received; when the receiving end monitors the PDCCH addressed by the C-RNTI, and the LCID received by the receiving end has a value of 65 and the MAC CE does not include G-RNTI, the receiving end uses the discontinuous reception short cycle for the multicast corresponding to G-RNTI1 for the multicast service corresponding to G-RNTI1 being received.

[0123] [Table 4] Table 4: LCID assignment value table for the fourth type

[0124] When one G-RNTI is included in the MAC CE, the receiving end uses the short discontinuous reception cycle for multicast or the long discontinuous reception cycle for multicast corresponding to the G-RNTI for the service corresponding to the G-RNTI, where the G-RNTI included in the MAC CE is the same as the G-RNTI indicated in the LCID received by the receiving end. Correspondingly, one Session ID or TMGI is further included in the MAC CE, and the short discontinuous reception cycle for multicast or the long discontinuous reception cycle for multicast corresponding to the Session ID or TMGI is used. The operation when a Session ID or TMGI is included is the same as the operation when a G-RNTI is included, and will not be described again.

[0125] If the MAC CE includes multiple G-RNTIs, the receiving end may further use a multicast-targeted DREC short cycle or a multicast-targeted DREC long cycle for each of the multiple services corresponding to the multiple G-RNTIs received by the receiving end. For each G-RNTI included in the MAC CE, the receiving end may sequentially determine whether the receiving end is in a user equipment group corresponding to the G-RNTI, that is, whether the receiving end receives a service corresponding to the G-RNTI. If the result is NO, the G-RNTI may be ignored and no operation may be performed. If the result is YES, the multicast-targeted DREC short cycle or multicast-targeted DREC long cycle corresponding to the G-RNTI may be used for the service corresponding to the G-RNTI. Correspondingly, if the MAC CE further includes multiple Session IDs or TMGIs, the multicast-targeted DREC short cycle or multicast-targeted DREC long cycle corresponding to the Session IDs or TMGIs may be used. The operation involving a Session ID or TMGI is the same as the operation involving a G-RNTI, and will not be described again.

[0126] Furthermore, the above-mentioned "Common Long DRX command and Common DRX Command", "Multicast Common Long DRX command and Multicast Common DRX command", "G-RNTI1Long DRX command MAC CE corresponding to G-RNTI1 and G-RNTI1DRX command MAC CE corresponding to G-RNTI1", "G-RNTI2Long DRX command MAC CE corresponding to G-RNTI2 and G-RNTI2DRX command MAC CE corresponding to G-RNTI2" ... "G-RNTI N Long-term discontinuous reception command G-RNTI corresponding to NLong DRX command MAC CE and G-RNTI N Intermittent reception command G-RNTI corresponding to N For "DRX command MAC CE", any combination can be added in the LCID assignment value table.

[0127] The present application further provides a method for transmitting an intermittent reception command, wherein the intermittent reception command is a MAC layer message, and a G-RNTI, and / or a temporary mobile group identifier, and / or a session identifier are indicated in the intermittent reception command and / or its corresponding MAC subheader.

[0128] Specifically, the discontinuous reception command sent by the transmitting end is a MAC layer message, and the transmitting end may indicate the G-RNTI, and / or the temporary mobile group identifier, and / or the session identifier in the discontinuous reception command, i.e., the MAC layer message, and send the discontinuous reception command, i.e., the MAC layer message, to the receiving end; may indicate the G-RNTI, and / or the temporary mobile group identifier, and / or the session identifier in the MAC sub-header corresponding to the MAC layer message and send the discontinuous reception command, i.e., the MAC layer message, to the receiving end; or may indicate the G-RNTI, and / or the temporary mobile group identifier, and / or the session identifier in both the MAC layer message and its corresponding MAC sub-header and send the discontinuous reception command, i.e., the MAC layer message, to the receiving end, thereby enabling the receiving end to receive the service corresponding to the G-RNTI, and / or the temporary mobile group identifier, and / or the session identifier in a discontinuous reception manner after receiving the MAC layer message and its corresponding MAC sub-header.

[0129] In addition, the present application does not limit the method of indicating the G-RNTI, and the G-RNTI, and / or temporary mobile group identifier, and / or session identifier may be directly included in the discontinuous reception command and / or the corresponding MAC sub-header, or information corresponding to the G-RNTI, and / or temporary mobile group identifier, and / or session identifier may be marked in the discontinuous reception command and / or the corresponding MAC sub-header.

[0130] Preferably, the present application further provides a method for receiving a discontinuous reception command in which a G-RNTI, and / or a Temporary Mobile Group Identifier, and / or a Session Identifier is indicated in the discontinuous reception command and / or its corresponding MAC subheader.

[0131] Specifically, if the discontinuous reception command of the receiving end is a MAC layer message, i.e., MAC CE, it can further determine whether G-RNTI is indicated in MAC CE, or whether G-RNTI is indicated in the MAC sub-header corresponding to MAC CE, or whether G-RNTI is indicated in both MAC CE and its corresponding MAC sub-header. If any of the above conditions is met, the receiving end will receive the service corresponding to G-RNTI in a discontinuous reception manner.

[0132] Preferably, the present application further provides a method for receiving an intermittent reception command including at least a G-RNTI. Specifically, the intermittent reception command may include one G-RNTI or multiple G-RNTIs.

[0133] If the discontinuous reception command is a MAC CE, regardless of whether the MAC CE contains only one G-RNTI, multiple G-RNTIs, or no G-RNTI, after receiving the MAC CE, the receiving end needs to use the corresponding discontinuous reception cycle in conjunction with the address status of the PDCCH and the indication status of the MAC subheader corresponding to the MAC CE. The specific operation status has been clearly described above and will not be repeated here.

[0134] In addition, the method of including the G-RNTI in the MAC CE may include the G-RNTI directly, or may include an identifier of the service corresponding to the G-RNTI, which may be called a Session ID.

[0135] In addition, the MAC CE may directly include at least one G-RNTI and / or corresponding session ID and / or corresponding session ID, or may not include a G-RNTI and / or corresponding session ID and / or corresponding session ID, i.e., may be 0 bits in length.

[0136] The following provides four examples to specifically describe the implementation process of the present invention.

[0137] Example 1 In this embodiment, as shown in FIG. Step A1, in which the receiving end checks whether the discontinuous reception command indicated by the PDCCH addressed by the G-RNTI is received, and if YES, proceeds to step A21 to step A23; For a service corresponding to the G-RNTI, the receiving end uses step A21 of drx-LongCycle-PTM for the G-RNTI; Step A22 in which the receiving end stops the drx-onDurationTimerPTM for the G-RNTI; The receiving end provides another method for receiving the discontinuous reception command, including step A23 of stopping the drx-InactivityTimerPTM for the G-RNTI.

[0138] When step A22 is executed, the drx-onDurationTimerPTM may be stopped directly, or the drx-onDurationTimerPTM may be stopped by first determining whether the drx-onDurationTimerPTM is running in the discontinuous reception setting for multicast corresponding to the G-RNTI, and if the result is YES, the drx-onDurationTimerPTM may be stopped. There is no essential difference between these two operation methods, except that the latter has higher stability in the execution of the algorithm during the operation process.

[0139] When step A23 is executed, the drx-InactivityTimerPTM may be stopped directly, or it may be determined first whether the drx-InactivityTimerPTM is running in the discontinuous reception setting for multicast corresponding to the G-RNTI, and if the result is YES, the drx-InactivityTimerPTM may be stopped. There is no essential difference between these two operation methods, except that the latter has higher stability in algorithm execution during the operation process.

[0140] Preferably, during execution, this embodiment may further execute A24 to stop the discontinuous reception short cycle counter for multicast, or determine whether the discontinuous reception short cycle counter for multicast in the discontinuous reception setting for multicast corresponding to G-RNTI is running, and if the determination is YES, to stop the discontinuous reception short cycle counter for multicast. This step takes into consideration the situation where the discontinuous reception short cycle counter for multicast is running so that the receiving end uses the drx-LongCycle-PTM corresponding to the G-RNTI normally and without interference. Furthermore, in executing step A24, the receiving end stops the discontinuous reception short cycle counter for multicast corresponding to the G-RNTI at the first symbol after receiving the discontinuous reception command.

[0141] This embodiment is often applied to a scenario in which the service corresponding to the G-RNTI becomes sparse over a certain period of time.

[0142] In this embodiment, the discontinuous reception command received at this time is a MAC CE, and the LCID included in the MAC subheader corresponding to the MAC CE is used to indicate the corresponding MAC CE as the discontinuous reception command.

[0143] Wherein, the LCID can be used to indicate the corresponding MAC CE as a discontinuous reception command for unicast service or a long discontinuous reception command for unicast service; Or, the LCID can be used to indicate the corresponding MAC CE as a common discontinuous reception command or a common long discontinuous reception command; Or, the LCID can be used to indicate the corresponding MAC CE as a discontinuous reception command for all multicast services or a long discontinuous reception command for all multicast services; Alternatively, the LCID can be used to instruct the corresponding MAC CE as an discontinuous reception command targeted at the multicast corresponding to the G-RNTI or Session ID or TMGI, or as a long discontinuous reception command targeted at the multicast corresponding to the G-RNTI or Session ID or TMGI.

[0144] The LCID value may be 59, or 60, or some other value.

[0145] In this embodiment, the MAC CE may be 0 bits in length, or may include a G-RNTI and / or a service identifier or TMGI corresponding to the G-RNTI.

[0146] Example 2 In this embodiment, as shown in FIG. Step B1, in which the receiving end checks whether an discontinuous reception command is received, which is indicated by a PDCCH addressed by a C-RNTI or a G-RNTI and indicates one or more G-RNTIs and / or service identifiers Session ID(s) and / or TMGI corresponding to the G-RNTIs, and if the result is YES, the receiving end proceeds to any one of steps B21 to B23; For a service corresponding to the G-RNTI, the receiving end uses the drx-LongCycle-PTM for the G-RNTI in step B21; Step B22, in which the receiving end stops the drx-onDurationTimerPTM for the G-RNTI; The receiving end provides another method for receiving the discontinuous reception command, including step B23 of stopping the drx-InactivityTimerPTM for the G-RNTI.

[0147] In step B1, it is necessary to sequentially determine each G-RNTI or TMGI or Session ID(s) included in the MAC CE, and sequentially determine whether the receiving end is in the user equipment group corresponding to the G-RNTI or Session ID, that is, whether the receiving end is receiving the service corresponding to the G-RNTI or Session ID. If the result is NO, the G-RNTI is ignored and steps B21 to B23 are not executed. If the result is YES, steps B21 to B23 are executed, and it is important to note that the discontinuous reception short cycle or drx-LongCycle-PTM for the multicast corresponding to the G-RNTI is used for the service corresponding to the G-RNTI or Session ID.

[0148] When performing step B22, the drx-onDurationTimerPTM may be stopped directly, or the drx-onDurationTimerPTM may be first determined to be running in the discontinuous reception setting for multicast corresponding to the G-RNTI, and if the result is YES, the drx-onDurationTimerPTM may be stopped. There is no essential difference between these two operation methods, except that the latter has higher stability in algorithm execution during the operation process.

[0149] When step B23 is executed, the drx-InactivityTimerPTM may be stopped directly, or the drx-InactivityTimerPTM may be first determined to be running in the discontinuous reception setting for multicast corresponding to the G-RNTI, and if the result is YES, the drx-InactivityTimerPTM may be stopped. There is no essential difference between these two operation methods, except that the latter has higher stability in the execution of the algorithm during the operation process.

[0150] Preferably, during execution, this embodiment may further execute B24 to stop the discontinuous reception short cycle counter for multicast, or determine whether the discontinuous reception short cycle counter for multicast in the discontinuous reception setting for multicast corresponding to G-RNTI is running, and if the determination is YES, to stop the discontinuous reception short cycle counter for multicast. This step takes into consideration the situation where the discontinuous reception short cycle counter for multicast is running so that the receiving end uses the drx-LongCycle-PTM corresponding to the G-RNTI normally and without interference. Furthermore, in executing step B24, the receiving end stops the discontinuous reception short cycle counter for multicast corresponding to the G-RNTI at the first symbol after receiving the discontinuous reception command.

[0151] This embodiment is often applied to a scenario in which the receiving end is instructed to receive a service corresponding to a G-RNTI via a dedicated path, or the current receiving end has limited power budget and the service corresponding to the G-RNTI, TMGI, or Session ID has a low priority level among the currently received services.

[0152] In this embodiment, the discontinuous reception command received at this time is a MAC CE, and the LCID included in the MAC subheader corresponding to the MAC CE is used to indicate the corresponding MAC CE as the discontinuous reception command.

[0153] Among them, if the MAC CE does not include G-RNTI, The LCID can be used to indicate the corresponding MAC CE as an intermittent reception command, If the MAC CE contains one G-RNTI, The LCID can be used to indicate the corresponding MAC CE as a common discontinuous receive command or a common long discontinuous receive command; Alternatively, the LCID can be used to indicate the corresponding MAC CE as a multicast-targeted discontinuous reception command or a multicast-targeted long discontinuous reception command; Alternatively, the LCID can be used to instruct the corresponding MAC CE as an discontinuous reception command targeted at the multicast corresponding to the G-RNTI or Session ID or TMGI, or as a long discontinuous reception command targeted at the multicast corresponding to the G-RNTI or Session ID or TMGI.

[0154] On the other hand, if the MAC CE contains multiple G-RNTIs, The LCID can be used to indicate the corresponding MAC CE as a common discontinuous receive command or a common long discontinuous receive command; Alternatively, the LCID can be used to indicate the corresponding MAC CE as a multicast-targeted discontinuous reception command or a multicast-targeted long discontinuous reception command.

[0155] In this embodiment, the MAC CE may not include a G-RNTI and may be 0 bits in length, or may include one or more G-RNTIs and / or a Session ID, which is an identifier of a service corresponding to the G-RNTI.

[0156] Example 3 The method of receiving the intermittent reception command implemented in this embodiment is as shown in FIG. Step C1, in which the receiving end checks whether the discontinuous reception command indicated by the PDCCH addressed by the G-RNTI is received, and if YES, proceeds to step C2; Step C2 in which the receiving end checks whether the drx-shortcyclePTM corresponding to the G-RNTI is set, and if the drx-shortcyclePTM corresponding to the G-RNTI is set, the receiving end proceeds to step C3, and if the drx-shortcyclePTM corresponding to the G-RNTI is not set, the receiving end proceeds to step C4; For a service corresponding to the G-RNTI, the receiving end starts or restarts the drx-ShortCycleTimerPTM corresponding to the G-RNTI and / or uses the drx-shortcyclePTM corresponding to the G-RNTI; and step C3. Step C4 includes, for a service corresponding to the G-RNTI, the receiving end using a long DRX cycle corresponding to the G-RNTI.

[0157] In step C3, the receiving end starts the intermittent reception short cycle counter for multicast in the intermittent reception setting for multicast corresponding to the G-RNTI at the first symbol after receiving the intermittent reception command.

[0158] This embodiment is often applied to a scenario in which the service corresponding to the G-RNTI becomes sparse over a certain period of time.

[0159] In this embodiment, the discontinuous reception command received at this time is a MAC CE, and the LCID included in the MAC subheader corresponding to the MAC CE is used to indicate the corresponding MAC CE as the discontinuous reception command.

[0160] Wherein, the LCID can be used to indicate the corresponding MAC CE as a discontinuous reception command for unicast service or a long discontinuous reception command for unicast service; Or, the LCID can be used to indicate the corresponding MAC CE as a common discontinuous reception command or a common long discontinuous reception command; Alternatively, the LCID can be used to indicate the corresponding MAC CE as a discontinuous reception command for all multicast services or a long discontinuous reception command for multicast for all multicast services; Alternatively, the LCID can be used to instruct the corresponding MAC CE as an discontinuous reception command targeted at the multicast corresponding to the G-RNTI or Session ID or TMGI, or as a long discontinuous reception command targeted at the multicast corresponding to the G-RNTI or Session ID or TMGI.

[0161] In this embodiment, the MAC CE may be 0 bits in length, and may include a G-RNTI and / or a service identifier Session ID or TMGI corresponding to the G-RNTI.

[0162] Example 4 In this embodiment, as shown in FIG. The receiving end checks whether an discontinuous reception command is received, which is indicated by a PDCCH addressed by a C-RNTI or a G-RNTI and indicates one or more G-RNTIs and / or service identifiers Session ID(s) and / or TMGI corresponding to the G-RNTIs, and if the result is YES, proceeds to step D2; Step D2 in which the receiving end checks whether a drx-shortcycle PTM corresponding to the G-RNTI is set, and if a drx-shortcycle PTM corresponding to the G-RNTI is set, proceeds to step D3, and if a drx-shortcycle PTM corresponding to the G-RNTI is not set, proceeds to step D4; Step D3: for a service corresponding to the G-RNTI, the receiving end starts or restarts the drx-ShortCycleTimerPTM corresponding to the G-RNTI and / or uses the drx-shortcyclePTM corresponding to the G-RNTI; For a service corresponding to the G-RNTI, the receiving end provides a receiving method of the discontinuous reception command, including step D4, using a long DRX cycle corresponding to the G-RNTI.

[0163] In step D1, it is necessary to sequentially determine each G-RNTI or Session ID(s) included in the MAC CE to determine whether the receiving end is in the user equipment group corresponding to the G-RNTI or Session ID, that is, whether the receiving end is receiving the service corresponding to the G-RNTI or Session ID. If the result is NO, the G-RNTI is ignored and steps D2 to D4 are not executed. If the result is YES, steps D2 to D4 are executed and it is important to note that the discontinuous reception short cycle or drx-LongCycle-PTM for the multicast corresponding to the G-RNTI is used for the service corresponding to the G-RNTI or Session ID.

[0164] In step D3, the receiving end starts the discontinuous reception short cycle counter for multicast in the discontinuous reception setting for multicast corresponding to the G-RNTI at the first symbol after receiving the discontinuous reception command.

[0168] On the other hand, if the MAC CE contains multiple G-RNTIs, Session IDs, or TMGIs, The LCID can be used to indicate the corresponding MAC CE as a common discontinuous receive command or a common long discontinuous receive command; Alternatively, the LCID can be used to indicate the corresponding MAC CE as a multicast-targeted discontinuous reception command or a multicast-targeted long discontinuous reception command.

[0169] In this embodiment, the MAC CE may be 0 bits in length, and may include one or more G-RNTIs and / or the identifier Session ID or TMGI of the service corresponding to the G-RNTIs.
