[0002] In wireless communication systems, discontinuous reception (DRX) has been introduced to ensure efficient data transmission while reducing the power consumption of terminal devices.

[0003] When the network device sets the DRX function for the terminal device, the terminal device can enter a sleep state at some moments, so that the terminal device does not need to continuously monitor a physical downlink control channel (PDCCH). When the terminal device needs to monitor the PDCCH, the terminal device can be woken up from the sleep state, so as to reduce the power consumption of the terminal device to a certain extent.

[0165] The terms "system" and "network" may be used interchangeably in embodiments of the present application.

[0166] The following further describes the technical solutions in the present application in detail with reference to the accompanying drawings herein.

[0167] FIG. 1 is a schematic diagram of a communication system to which an embodiment of the present application is applied. As shown in FIG. 1, a terminal device 130 can access a wireless network, for example, communicate with other terminal devices, to obtain a service of an external network (e.g., the Internet) through the wireless network or communicate with other devices through the wireless network. The wireless network includes a radio access network (RAN) device 110 and a core network (CN) device 120. The RAN device 110 is configured to enable the terminal device 130 to access the wireless network, and the CN device 120 is configured to manage the terminal device and provide a gateway for communication with the external network. It should be understood that the number of devices in the communication system shown in FIG. 1 is used merely as an example. The embodiment of the present application is not limited to such. During practical application, the communication system may further include more terminal devices 130 and more RAN devices 110, and may further include other devices.

[0168] FIG. 2a is a schematic diagram of another network architecture to which an embodiment of the present application is applied. As shown in FIG. 2a, the network architecture includes a CN device, a RAN device, and a terminal device. The RAN device includes a baseband device and a radio frequency device. The baseband device may be implemented by one node, or may be implemented by multiple nodes. The radio frequency device may be implemented independently apart from the baseband device, or may be integrated into the baseband, or some functions are implemented independently and some functions are integrated into the baseband device. For example, in an LTE communication system, a RAN device (eNB) includes a baseband device and a radio frequency device. The radio frequency device may be located remotely relative to the baseband device. For example, a remote radio unit (RRU) is a remote radio unit located relative to the BBU.

[0169] The communication between the RAN device and the terminal device follows a specific protocol layer structure. For example, the control plane protocol layer structure may include protocol layer functions such as a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, and a physical layer. The user plane protocol layer structure may include protocol layer functions such as a PDCP layer, an RLC layer, a MAC layer, and a physical layer. In a possible implementation, a service data adaptation protocol (SDAP) layer may be further included above the PDCP layer.

[0170] A RAN device may implement the functions of protocol layers such as RRC, PDCP, RLC, and MAC by using one node or multiple nodes. For example, in an evolved structure, a RAN device may include a CU and a DU, and multiple DUs may be controlled by one CU in a centralized manner. As shown in Figure 2a, the CU and DU may be divided based on the protocol layers of a radio network. For example, the functions of the PDCP layer and the protocol layers above the PDCP layer are set on the CU, and the functions of the protocol layers below the PDCP, such as the RLC layer and the MAC layer, are set on the DU.

[0171] The division based on the protocol layer is only an example, and the division may alternatively be performed based on other protocol layers, such as the RLC layer. The RLC layer and functions of the protocol layers above the RLC layer are set on the CU, and functions of the protocol layers below the RLC layer are set on the DU. Alternatively, the division is performed on the protocol layers. For example, some functions of the RLC layer and functions of the protocol layers above the RLC layer are set on the CU, and the remaining functions of the RLC layer and functions of the protocol layers below the RLC layer are set on the DU. Also, the division may alternatively be performed in other ways. For example, the division is performed based on delay. Functions whose processing time needs to satisfy delay requirements are set on the DU, and functions whose processing time does not need to satisfy delay requirements are set on the CU.

[0172] Furthermore, the radio frequency device may not be located in the DU, may be independently integrated, may be integrated in the DU, or may be partly located remotely from the DU and the remaining part integrated in the DU, which is not limited here.

[0173] Figure 2b is a schematic diagram of another network architecture to which an embodiment of the present application is applied. In contrast to the network architecture shown in Figure 2a, in Figure 2b, the control plane (CP) and user plane (UP) of a CU are further separated and may be implemented as different entities, i.e., a control plane (CP) CU entity (i.e., a CU-CP entity) and a user plane (UP) CU entity (i.e., a CU-UP entity).

[0174] In the above network architecture, the signaling generated by the CU may be sent to the terminal device via the DU, or the signaling generated by the terminal device may be sent to the CU via the DU. The DU may transparently transmit the signaling to the terminal device or the CU by directly encapsulating the signaling in the protocol layer without parsing the signaling. In the following embodiment, the transmission or reception of the signaling by the DU includes this scenario when the transmission of such signaling between the DU and the terminal device is included. For example, the signaling of the RRC layer or the PDCP layer is finally processed as the signaling of the PHY layer and transmitted to the terminal device, or converted from the received signaling of the PHY layer. In this architecture, the signaling of the RRC layer or the PDCP layer may be transmitted by the DU, or may be transmitted by the DU and the radio frequency device.

[0175] The network architecture shown in FIG. 1, FIG. 2a, or FIG. 2b is applicable to communication systems in various radio access technologies (RATs). For example, the communication system may be an LTE communication system, a 5G (also called new radio (NR)) communication system, a transition system between an LTE communication system and a 5G communication system, or indeed a future communication system, where the transition system may be called a 4.5G communication system. The network architecture and service scenarios described in the embodiments of the present application are intended to more clearly describe the technical solutions in the embodiments of the present application, and do not constitute limitations on the technical solutions provided in the embodiments of the present application. Those skilled in the art may recognize that with the evolution of communication network architectures and the emergence of new service scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems. For example, the present invention may be applicable to broadcast-multicast scenarios.

[0176] The apparatus in the following embodiments of the present application may be arranged in a terminal device or a network device based on the functions implemented by the apparatus. When the above CU-DU structure is used, the network device may be a CU node, a DU node, or a RAN device including a CU node and a DU node.

[0177] The multicast or multicast service referred to in the embodiments of this application may be a multicast and broadcast service (or multicast / broadcast service, MBS) in a new radio (NR) system. MBS was introduced in 3GPP to efficiently use the resources of a mobile communication network, and provides a point-to-multipoint service in a mobile communication network in which a data source transmits data to multiple users, thereby realizing network resource sharing and improving the utilization of resources, especially air interface resources. NR MBS supports multicast and broadcast.

[0178] In the embodiments of the present application, "multicast" can alternatively be replaced by terms such as "multiple simultaneous transmissions." Thus, a multicast service can alternatively be replaced by a multiple simultaneous transmission service.

[0179] The same service and / or the same content data can be provided simultaneously to a group / multiple terminal devices by multicasting.

[0180] A multicast may be specific to a particular group of terminal devices, and the terminal devices may need to perform a "group join process."

[0181] Thus, unicasting can be understood as providing the same service and / or the same content data to one terminal device at the same time, whereas unicasting can be understood as one piece of data having to be sent to each device separately if that data needs to be sent to multiple devices.

[0182] In wireless communication systems, in order to further reduce the power consumption of terminal devices while ensuring effective data transmission, a discontinuous reception (DRX) function is introduced to control the behavior of monitoring the physical downlink control channel PDCCH by the terminal device. When a network device configures the DRX function for a terminal device, the terminal device can enter a sleep state at some moments, so that the terminal device does not need to continuously monitor the physical downlink control channel PDCCH. When the terminal device needs to monitor the PDCCH, the terminal device is woken up from the sleep state, which can reduce the power consumption of the terminal device to a certain extent.

[0183] The following briefly describes DRX with reference to FIG. 3. FIG. 3 is a schematic diagram of a DRX cycle according to an embodiment of the present application. As shown in FIG. 3, a DRX cycle may include a duration (e.g., an on duration) or a wake-up time (e.g., an on duration) and a sleep time (e.g., a DRX opportunity). The on duration is the time that the terminal device waits to receive a PDCCH after being woken up. During this period, the terminal device monitors the PDCCH. If the terminal device successfully decodes the PDCCH, the terminal device may remain in a wake-up state or extend the active time. The DRX period opportunity is the sleep time of the terminal device. During this period, the terminal device does not need to monitor the PDCCH and can reduce power consumption. It can be understood that the longer the sleep time of the terminal device, the lower the power consumption of the terminal device, but the higher the delay of the service transmission of the terminal device accordingly.

[0184] The DRX capability of the terminal device may be configured by the network device. It should be understood that even if the network device configures the DRX capability for the terminal device, the terminal device may monitor the PDCCH according to the requirements of other medium access control MAC layer processes. That is, if the other MAC layer processes require the terminal device to continue to monitor the PDCCH, the terminal device needs to continuously monitor the PDCCH regardless of the current DRX status.

[0185] (1) Unicast DRX:

[0186] If no DRX group is configured (or in other words, in R15), DRX parameters are configured by the network device for each terminal device MAC entity or for the terminal device, i.e., the MAC entity of one terminal device uses one set of DRX parameters.

[0187] In a carrier aggregation (CA) scenario, a terminal device performs one DRX for all active cells using the same set of DRX parameters.

[0188] In a multi-radio dual connectivity (MR-DC) scenario, a master node (MN) and a secondary node (SN) correspond to the MAC entity of a terminal device separately. Therefore, the terminal device has two independent sets of DRX parameters and performs two DRX for MN and SN. In other words, the terminal device performs one DRX with one set of DRX parameters for all active serving cells in a master cell group (MCG), and another DRX with another set of DRX parameters for all active serving cells in a secondary cell group (SCG).

[0189] If a DRX group is not configured, the DRX active time may include any one or more of the following: the operation time of the drx-onDurationTimer; the operation time of the drx-InactivityTimer; the operation time of the drx-RetransmissionTimerDL; the operation time of the drx-RetransmissionTimerUL; the operation time of the drx-RetransmissionTimerSL; the operation time of the drx-RetransmissionTimerDL-PTM corresponding to multicast; the time during which a scheduling request SR is transmitted on the PUCCH and the SR is waiting for processing; the time during which a PDCCH scrambled by using the C-RNTI and indicating a new transmission is not received after successfully receiving an RAR in a non-contention based random access process (i.e., after a successful non-contention based RA), etc.

[0190] The network device controls the DRX operation by setting the following parameters by using RRC messages: drx-onDurationTimer: This is the period at the start of the DRX cycle. The position at which the drx-onDurationTimer starts can be calculated based on parameters set by the base station and a formula specified in the protocol. drx-InactivityTimer: The period after a PDCCH occasion during which the scheduling of a new uplink or downlink transmission is indicated. The terminal device receives a PDCCH indicating that there is a new uplink or downlink transmission (i.e. a new transmission is scheduled) and starts or restarts the drx-InactivityTimer. drx-RetransmissionTimerDL: The maximum duration until a DR retransmission is received. The drx-RetransmissionTimerDL is started if the drx-HARQ-RTT-TimerUL has elapsed and the data has not been successfully decoded. drx-RetransmissionTimerUL: The maximum duration until which a grant for a UR retransmission is received. At the first symbol after drx-HARQ-RTT-TimerUL has elapsed, the drx-RetransmissionTimerUL is started for the corresponding HARQ process. drx-HARQ-RTT-TimerDL: The minimum duration before the MAC entity expects to receive a DL allocation for HARQ retransmission. Either the terminal device receives a PDCCH indicating that a downlink transmission is present or the terminal device receives data in the configured downlink allocation and starts or restarts the drx-HARQ-RTT-TimerDL. drx-HARQ-RTT-TimerUL: the minimum duration before the MAC entity expects to receive a UL HARQ retransmission grant. The terminal device transmits a MAC protocol data unit (PDU) in a configured uplink grant or the terminal device receives a PDCCH indicating a UL transmission and starts or restarts drx-HARQ-RTT-TimerUL. ● drx-RetransmissionTimerSL: The maximum duration until a grant for SL retransmission is received. ● drx-HARQ-RTT-TimerSL: The minimum duration before which a grant for SL retransmission is expected to be received.

[0191] Compared to R15, the R16 standard protocol adds the features of DRX groups and DCI with CRC scrambled by power saving radio network temporary identifier (PS-RNTI, DCP) to unicast DRX.

[0192] Below is a brief explanation of DRX Groups and DCPs.

[0193] DRX group: In one MAC entity, different DRX groups are distinguished for different frequency ranges, in other words, DRX groups are distinguished for frequency ranges (FR1 and FR2), i.e. the concept of a secondary DRX group is introduced for cells in FR2.

[0194] For cells / DRX groups in FR1, there is a separate set of parameters, drx-onDurationTimer and drx-InactivityTimer, and for cells / DRX groups in FR2, there is a separate set of parameters, drx-onDurationTimer and drx-InactivityTimer. Other DRX parameters are common.

[0195] Each DRX group performs one DRX, i.e., in a MAC entity, there may be two DRX groups and two DRX are performed.

[0196] If a DRX group is configured, the active time of the DRX group may include any one or more of the following: an operation time of the drx-onDurationTimer for the DRX group; an operation time of the drx-InactivityTimer for the DRX group; an operation time of the drx-RetransmissionTimerDL corresponding to the DRX group (or of any cell in the DRX group); an operation time of the drx-RetransmissionTimerUL corresponding to the DRX group (or of any cell in the DRX group); an operation time of the drx-RetransmissionTimerSL corresponding to the DRX group (or of any cell in the DRX group); an operation time of the drx-RetransmissionTimerDL-PTM corresponding to the multicast corresponding to the DRX group; the time during which a scheduling request SR is transmitted on the PUCCH and the SR is waiting for processing; the time during which a PDCCH scrambled by using the C-RNTI and indicating a new transmission is not received after successfully receiving an RAR in the non-contention based random access process (i.e., after a successful non-contention based RA), etc.

[0197] DCP: When the network device configures the DCP function for the terminal device, the terminal device monitors the DCI including the CRC scrambled by the PS-RNTI before the drx-onDurationTimer is started to determine whether to start the drx-onDurationTimer, thereby further reducing the power consumption of the terminal device.

[0198] For example, when the DCP capability is configured for a terminal device, the terminal device may determine whether to start the drx-onDurationTimer based on several of the following methods.

[0199] Method 1: If a network device configures ps-wakeup for a terminal device and the terminal device does not detect a scrambled DCI by using the PS-RNTI, the terminal device may start a drx-onDurationTimer.

[0200] Method 2: If the network device does not configure ps-wakeup for the terminal device, and the terminal device detects a scrambled DCI by using the PS-RNTI, and the DCI instructs the terminal device to wake up, the terminal device starts the drx-onDurationTimer.

[0201] (2) Multicast DRX:

[0202] Multicast DRX and unicast DRX are independent, and multicast DRX parameters can be per group RNTI (G-RNTI) and / or per group configured scheduling RNTI (G-CS-RNTI), with multicast DRX being performed per G-RNTI and / or G-CS-RNTI.

[0203] Each multicast DRX active time may include any one or more of the following: drx-onDurationTimerPTM, drx-InactivityTimerPTM, or drx-RetransmissionTimerDL-PTM, which are specific to the G-RNTI or G-CS-RNTI.

[0204] The multicast DRX function may be described as follows:

[0205] The network device controls the multicast DRX operation by setting the following parameters by using RRC messages: drx-onDurationTimerPTM: This is the period at the start of the DRX cycle. The position at which drx-onDurationTimerPTM starts is calculated based on parameters set by the base station and a formula specified in the protocol. drx-InactivityTimerPTM: The period after a PDCCH occasion during which the scheduling of a new DL transmission is indicated. The terminal device receives a PDCCH indicating that there is a new uplink or downlink transmission (i.e. a new transmission is scheduled) and starts or restarts the drx-InactivityTimerPTM. drx-RetransmissionTimerDL-PTM: The maximum duration until a DR retransmission is received. If drx-HARQ-RTT-TimerDL-PTM has elapsed and the data was not successfully decoded, the drx-RetransmissionTimerDL-PTM is started. drx-HARQ-RTT-TimerDL-PTM: The minimum duration before a DL retransmission is expected to be received, the minimum duration before an expected DL retransmission, or the minimum duration before an expected DL retransmission is received. At the terminal, the device receives a PDCCH indicating that a downlink transmission is present or the terminal device receives data in the configured downlink allocation and starts or restarts the drx-HARQ-RTT-TimerDL-PTM.

[0206] (3)CSI report: The following briefly describes a solution in which a terminal device reports CSI to a network device in R15 and R16.

[0207] In R15 (or in other words, when DCP monitoring is not configured and DRX group is not configured), the solution for the terminal device to report CSI based on unicast DRX includes any one or more of the following: If symbol n is not within the active time of DRX, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH and skips transmitting the CSI on the terminal device PUCCH; or ● If CSI masking is configured for the terminal device and the drx-onDurationTimer is not running at symbol n, the terminal device skips transmitting CSI on the PUCCH.

[0208] In R16 (or in other words, when DCP monitoring is configured), the solution for the terminal device to report CSI based on unicast DRX includes any one or more of the following: ● if DCP monitoring is configured for the terminal device, symbol n is within the period of drx-onDurationTimer, the drx-onDurationTimer in the current DRX period has not started, and symbol n is not within the active time of DRX, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH; ● if DCP monitoring is configured for the terminal device, symbol n is within the period of drx-onDurationTimer, the drx-onDurationTimer in the current DRX period has not been started, symbol n is not within the active time of DRX, and ps-TransmitPeriodicL1-RSRP is not set by true for the terminal device, ps-TransmitPeriodicL1-RSRP being true indicates that the terminal device needs to report periodic CSI, which is L1-RSRP in this case, and the terminal device skips transmitting periodic CSI, which is L1-RSRP, on the PUCCH; ● if DCP monitoring is configured for the terminal device, symbol n is within the period of drx-onDurationTimer, the drx-onDurationTimer in the current DRX period has not been started, symbol n is not within the DRX active time, and ps-TransmitOtherPeriodicCSI is not set by true for the terminal device, ps-TransmitOtherPeriodicCSI being true indicates that the terminal device needs to report non-L1-RSRP periodic CSI in this case, and the terminal device skips transmitting non-L1-RSRP periodic CSI on the PUCCH; ● if DCP monitoring is not configured for the terminal device and symbol n is not within the period of drx-onDurationTimer, or if the drx-onDurationTimer in the current DRX period is started and symbol n is not within the active time of DRX, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH, and the terminal device skips transmitting the CSI on the PUCCH; ●If DCP monitoring is not configured for the terminal device and symbol n is not within the period of drx-onDurationTimer, or the drx-onDurationTimer in the current DRX period has started, CSI masking is configured for the terminal device, and the drx-onDurationTimer is not running at symbol n, the terminal device skips transmitting CSI on the PUCCH.

[0209] In R16 (or in other words, when DCP monitoring is configured), other solutions for a terminal device to report CSI based on unicast DRX include any one or more of the following: ● if symbol n is not within the period of drx-onDurationTimer, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH in the DRX group, and the terminal device skips transmitting the CSI on the PUCCH in the DRX group; ● If CSI masking is configured for the terminal device and the drx-onDurationTimer for the DRX group is not running at symbol n, the terminal device skips transmitting CSI on the PUCCH within the DRX group.

[0210] Please note that for the contents related to DRX and CSI reporting, please refer to 3GPP TS 38.321: “NR; Medium Access Control (MAC); Protocol specification”. The details will not be described again here.

[0211] It is known that in R15 and R16, there is no solution for how a terminal device reports CSI in the presence of multicast DRX, or in other words, in the presence of coexistence of unicast DRX and multicast DRX.

[0212] In a scenario where multicast DRX is not configured for some or all of the multicasts that the terminal device receives or joins, based on the prior art, if unicast DRX is not within the active time, or if neither multicast DRX nor unicast DRX is within the active time, the terminal device does not report CSI / SRS and cannot assist the base station in scheduling. In a scenario where multicast DRX is not configured for some or all of the multicasts that the terminal device receives or joins, how does the UE report CSI to facilitate the base station in multicast scheduling?

[0213] Furthermore, if a separate multicast DRX is configured for multicast, how does the UE report CSI?

[0214] In view of this, the embodiments of the present application provide a communication method and a communication device for reporting CSI in the case where unicast DRX and multicast DRX coexist.

[0215] It should be noted that in the embodiment of the present application, the terminal device is used as an example for description, or the terminal device may be replaced by a MAC entity of the terminal device, etc. This is not limited in the present application.

[0216] In the embodiments of the present application, no transmission may be understood as no reporting.

[0217] In the embodiment of the present application, sending may be understood as reporting.

[0218] In the present application, "not belonging to" is understood to mean "not in".

[0219] In the present application, "belonging to" is understood to mean "within".

[0220] In the embodiments of the present application, "associated" may be understood as "corresponding."

[0221] It should be noted that in an embodiment of the present application, the preset conditions include conditions 1 / 2 / 3 / 4 / 10 / 11 / 12 / 13 may be understood as when the preset conditions include a condition or when the preset conditions include conditions 1 / 2 / 3 / 4 / 10 / 11 / 12 / 13.

[0222] With reference to FIG. 4 and FIG. 5, the following describes in detail the communication method and communication device provided in the embodiments of the present application.

[0225] It should be noted that the first time may be understood as a period of time, or as a point in time or an instant. This is not limited in the embodiment of the present application. For example, the first time may alternatively be understood as any one or more of the following: one or more symbols, one or more slots, one or more subframes, one or more frames, etc. For example, the first time may be understood as symbol n. For example, the first time may be called a first instant.

[0226] It should be noted that condition 1 is the first condition, condition 2 is the second condition, condition 3 is the third condition, condition 4 is the fourth condition, condition 10 is the tenth condition, condition 11 is the eleventh condition, condition 12 is the twelfth condition, and condition 13 is the thirteenth condition.

[0230] It should be noted that in different conditions, the "first CSI" and / or "the terminal device skips transmitting the first CSI at the first time" may be different or may be the same, which is not limited in this application.

[0231] Condition 1: The first time does not belong to the active time of the first discontinuous reception DRX set, and the first time does not belong to the active time of the second DRX set.

[0232] The first DRX may be for controlling monitoring of control information specific to a terminal device.

[0233] It should be noted that the first DRX may alternatively be for controlling monitoring of control information that is not specific to a terminal device, which is not limited in this application.

[0234] For example, the first DRX may use the following RNTIs: cell RNTI (C-RNTI), cancellation indication RNTI (CI-RNTI), configured scheduling RNTI (CS-RNTI), interruption RNTI (INT-RNTI), slot format indication RNTI (SFI-RNTI), semi-persistent CSI RNTI (SP-CSI-RNTI), transmit power control physical uplink control channel RNTI (transmit power control-PUCCH-RNTI, TPC-PUCCH-RNTI), transmit power control physical uplink shared channel RNTI (transmit power control-PUSCH-RNTI, TPC-PUSCH-RNTI), transmit power control sounding reference signal RNTI (transmit power control-Sounding Reference Signal RNTI), and a transmission power control physical uplink shared channel RNTI (transmit power control-Sounding Reference Signal RNTI). The control information may be for controlling monitoring of control information specific to one or more of the sidelink RNTI (SL signal-RNTI, TPC-SRS-RNTI), AI-RNTI, sidelink RNTI (SL-RNTI), sidelink configured scheduling RNTI (SLCS-RNTI), or sidelink semi-persistent scheduling V2X RNTI (SL semi-persistent scheduling V-RNTI).

[0235] For example, the first DRX may be a unicast DRX or a DRX group (eg, one DRX group).

[0236] For example, the active time of the first DRX may include any one or more of the following: an operating time of an on-duration timer (e.g., drx-onDurationTimer) corresponding to the unicast; an operating time of an inactivity timer (e.g., drx-InactivityTimer) corresponding to the unicast; or an operating time of a retransmission timer corresponding to the unicast.

[0237] For example, the operation times of the retransmission timers corresponding to unicast may include any one or more of the following: a downlink retransmission timer (e.g., drx-RetransmissionTimerDL), an uplink retransmission timer (e.g., drx-RetransmissionTimerUL), or a sidelink retransmission timer (e.g., drx-RetransmissionTimerSL).

[0238] For example, the on-duration timer / on-duration timer corresponding to unicast indicates the duration that the terminal device waits to receive control information (eg, DCI) after being woken up.

[0239] For example, an inactivity timer / inactivity timer corresponding to a unicast may indicate a period of time after control information scheduling a new transmission or a period of time after new transmission data.

[0240] For example, a retransmission timer / retransmission timer corresponding to unicast indicates the duration for which the communication device receives retransmitted data / DCI and / or retransmission resources.

[0241] For example, a downlink retransmission timer / downlink retransmission timer corresponding to unicast indicates the duration for which the communication device receives downlink retransmission data / DCI and / or downlink retransmission resources.

[0242] For example, an uplink retransmission timer / uplink retransmission timer corresponding to unicast indicates the duration for which the communication device receives uplink retransmission data / DCI and / or uplink retransmission resources.

[0243] For example, the sidelink retransmission timer / sidelink retransmission timer corresponding to unicast indicates the duration for which the communication device receives sidelink retransmission data / DCI and / or sidelink retransmission resources.

[0244] Optionally, the active time of the first DRX may further include the operation time of a retransmission timer corresponding to multicast (eg, drx-RetransmissionTimerDL-PTM).

[0245] For example, the active time of the first DRX may include any one or more of the following: an operation time of an on-duration timer (e.g., drx-onDurationTimer) corresponding to the DRX group; an operation time of an inactivity timer (e.g., drx-InactivityTimer) corresponding to the DRX group; or an operation time of a retransmission timer corresponding to the DRX group.

[0246] Optionally, the active time of the first DRX may further include the operation time of a retransmission timer (eg, drx-RetransmissionTimerDL-PTM) corresponding to the multicast corresponding to the DRX group.

[0247] For example, a retransmission timer corresponding to a multicast indicates the duration for which a communication device receives retransmitted data / DCI and / or retransmission resources corresponding to the multicast.

[0248] It should be noted that the first DRX active time may further include other times, which is not limited in this application. For example, the content of the first DRX active time can be found in 3GPP TS 38.321: “NR; Medium Access Control (MAC); Protocol specification”.

[0249] The second DRX set may include at least one multicast DRX, and the at least one multicast DRX may include a first multicast DRX, and the first multicast DRX may be for controlling monitoring of control information related to the first multicast service.

[0250] For example, the second DRX set may include a DRX corresponding to a multicast / multicast service received by the terminal device, or a DRX corresponding to a multicast / multicast service in which the terminal device joins.

[0251] For example, the second DRX set may include a DRX corresponding to any multicast / multicast service / all multicast / multicast services received by the terminal device, or a DRX corresponding to any multicast / multicast service / all multicast / multicast services in which the terminal device participates.

[0252] For example, the second DRX set may be associated with a first multicast service set, where the first multicast service set may include the first multicast service.

[0253] For example, the first multicast service set may include multicasts / multicast services received by the terminal device or multicasts / multicast services in which the terminal device participates.

[0254] For example, the first multicast service set may include any multicast / multicast services / all multicast / multicast services received by the terminal device, or any multicast / multicast services / all multicast / multicast services in which the terminal device participates.

[0255] For example, the first multicast service may be understood as a multicast service associated with the first G-RNTI and / or the first G-CS-RNTI, or a multicast associated with the first G-RNTI and / or the first G-CS-RNTI.

[0256] For example, control information relating to the first multicast service may include or be understood as control information associated with (or scrambled using) the first G-RNTI and / or the first G-CS-RNTI, and / or control information scrambled using a unicast RNTI (e.g., a C-RNTI and / or a CS-RNTI).

[0257] It should be noted that the first multicast DRX may alternatively be for controlling the monitoring of other control information, which is not limited in this application.

[0258] For example, the active time of multicast DRX may include any one or more of the following: the operation time of an on-duration timer (e.g., drx-onDurationTimerPTM) corresponding to the multicast (e.g., G-RNTI and / or G-CS-RNTI); the operation time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to the multicast (e.g., G-RNTI and / or G-CS-RNTI); or the operation time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to the multicast (e.g., G-RNTI and / or G-CS-RNTI).

[0259] For example, the on-duration timer / on-duration timer corresponding to multicast indicates the duration that a terminal device waits to receive control information (eg, DCI) after being woken up.

[0260] For example, an inactivity timer corresponding to a multicast may indicate a period of time after control information scheduling a new transmission or a period of time after new transmitted data.

[0261] For example, the active time of the first DRX may include any one or more of the following: an operation time of an on-duration timer (e.g., drx-onDurationTimerPTM) corresponding to the first multicast service (or the first G-RNTI and / or the first G-CS-RNTI); an operation time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to the first multicast service (or the first G-RNTI and / or the first G-CS-RNTI); or an operation time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to the first multicast service (or the first G-RNTI and / or the first G-CS-RNTI).

[0374] For example, if condition 1, condition 6, and condition 7 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI or the third CSI at the first time.

[0375] For example, if DCP is configured for a terminal device, and symbol n is within the duration of the on-duration timer corresponding to unicast, and the on-duration timer corresponding to unicast is not started or restarted, and symbol n is neither within the active time of unicast DRX nor within the active time of multicast DRX, the terminal device shall: skipping, by the terminal device, transmitting semi-persistent CSI configured on a PUSCH; If the terminal device is not configured to need to report L1-RSRP periodic CSI or L1-RSRP CSI, the terminal device skips transmitting L1-RSRP periodic CSI on the PUCCH; or If the terminal device is not configured to need to report non-L1-RSRP periodic CSI or non-L1-RSRP CSI, the terminal device may skip transmitting non-L1-RSRP periodic CSI on the PUCCH. Execute one or more of the following:

[0376] For example, if DCP is configured for a terminal device, and symbol n is within the duration of the on-duration timer corresponding to unicast, and the on-duration timer corresponding to unicast is not started or restarted, and symbol n is neither within the active time of a DRX group nor within the active time of a multicast DRX, then for or within the DRX group, the terminal device shall: skipping, by the terminal device, transmitting semi-persistent CSI configured on a PUSCH; If the terminal device is not configured to need to report L1-RSRP periodic CSI or L1-RSRP CSI, the terminal device skips transmitting L1-RSRP periodic CSI on the PUCCH; or If the terminal device is not configured to need to report non-L1-RSRP periodic CSI or non-L1-RSRP CSI, the terminal device may skip transmitting non-L1-RSRP periodic CSI on the PUCCH. Execute one or more of the following:

[0377] Condition 2: The first time does not belong to the active time of the first DRX set, and the first time belongs to the active time of the third DRX set.

[0378] The third DRX set includes at least one multicast DRX, and the at least one multicast DRX includes a second multicast DRX, where the second multicast DRX is for controlling monitoring of control information related to the second multicast service.

[0379] For example, the third DRX set may include a DRX corresponding to a multicast / multicast service received by the terminal device, or a DRX corresponding to a multicast / multicast service in which the terminal device joins.

[0380] For example, the third DRX set may be associated with a second multicast service set, where the second multicast service set may include a second multicast service.

[0381] For example, the second multicast service set may include multicasts / multicast services received by the terminal device or multicasts / multicast services in which the terminal device joins.

[0382] For example, the second multicast service may be understood as a multicast service associated with the second G-RNTI and / or the second G-CS-RNTI, or a multicast associated with the second G-RNTI and / or the second G-CS-RNTI.

[0383] For example, control information regarding the second multicast service may include / be understood as control information associated with (or scrambled by using) the second G-RNTI and / or the second G-CS-RNTI, and / or control information scrambled by using a unicast RNTI (e.g., a C-RNTI and / or a CS-RNTI).

[0384] It should be noted that the second multicast DRX may alternatively be for controlling the monitoring of other control information, which is not limited in this application.

[0385] For example, the active time of the second multicast DRX may include any one or more of the following: an operation time of an on-duration timer (e.g., drx-onDurationTimerPTM) corresponding to the second multicast service (or the second G-RNTI and / or the second G-CS-RNTI); an operation time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to the second multicast service (or the second G-RNTI and / or the second G-CS-RNTI); or an operation time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to the second multicast service (or the second G-RNTI and / or the second G-CS-RNTI).

[0386] For example, the active time of the third DRX set may include any one or more of the following: an active time of a DRX set corresponding to the second multicast service set, an active time of a DRX set corresponding to a G-RNTI set and / or a G-CS-RNTI set corresponding to the second multicast service set, or an active time of a DRX set corresponding to a G-RNTI set and / or a G-CS-RNTI set corresponding to the third DRX set.

[0387] For example, the active time of the third DRX set may include any one or more of the following operation times: drx-onDurationTimerPTM, drx-InactivityTimerPTM, or drx-RetransmissionTimerDL-PTM, which are specific to the G-RNTI set and / or G-CS-RNTI set corresponding to the third DRX set.

[0388] It should be noted that the active time of the third DRX set may further include other times, which is not limited in this application.

[0389] Optionally, the pre-set condition may include condition 2, and "the terminal device transmits the first CSI at the first time" may include, for the third cell set, skipping the terminal device from transmitting the first CSI at the first time.

[0390] The third cell set includes at least one cell, and the third cell set is not associated with a third DRX set.

[0391] It should be noted that "for the third cell set, the terminal device skips transmitting the first CSI at the first time" may include / be understood as any one of the following: the terminal device skipping transmitting a CSI (e.g., the first CSI) within the third cell set at the first time, or the terminal device skipping transmitting a CSI specific to the third cell set (e.g., the first CSI) at the first time.

[0392] It should be noted that when "the terminal device skips transmitting CSI (e.g., the first CSI) in the third cell set at the first time," whether the terminal device transmits CSI specific to the third cell set in another cell or cell group is not limited in this application.

[0393] It should be noted that when "the terminal device skips transmitting CSI specific to the third cell set (e.g., the first CSI) at the first time," whether the terminal device transmits CSI specific to other cells or cell sets within the third cell set is not limited in this application.

[0394] For example, the sixth cell set is associated with the third DRX set or the second multicast service set.

[0395] The sixth set of cells includes at least one cell.

[0396] The third cell set not being associated with the third DRX set may be understood as the third cell set not being associated with the second multicast service set.

[0397] For example, the third cell set may be understood as / include a cell / cell set other than the cell / cell set associated with the second multicast service set, or a cell / cell set other than the sixth cell set.

[0398] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1. If the first time is not within the unicast active time but within the multicast DRX active time corresponding to multicast 1, for cells 2 and 3, the terminal device skips transmitting the first CSI at the first time. The first DRX is unicast DRX, the third DRX set is multicast DRX corresponding to multicast 1, the third cell set is cell 2 and cell 3, and the sixth cell set is cell 1.

[0399] Optionally, a third set of cells is associated with the first DRX.

[0400] For example, the association of a third cell set with the first DRX may be understood as the cells included in the third cell set using the same DRX parameters (e.g., parameters relating to the first DRX) and the reception of control information of the cells included in the third cell set being controlled by the same DRX (e.g., the first DRX).

[0401] Optionally, the sixth cell set is associated with the first DRX.

[0402] For example, the association of a sixth cell set with the first DRX may be understood as the cells included in the sixth cell set using the same DRX parameters (e.g., parameters relating to the first DRX) and the reception of control information of the cells included in the sixth cell set being controlled by the same DRX (e.g., the first DRX).

[0403] Optionally, the first set of cells includes a third set of cells.

[0404] For example, the third cell set is a subset of the first cell set, or the third cell set is equal to the first cell set.

[0405] For example, the first cell set includes the sixth cell set.

[0406] For example, the sixth cell set is a subset of the first cell set, or the sixth cell set is equal to the first cell set.

[0407] Optionally, the first set of cells includes a third set of cells and a sixth set of cells.

[0408] For example, the third cell set and the sixth cell set are equal to the first cell set.

[0409] For example, the third cell set and the sixth cell set do not have an intersection set.

[0410] For example, the third DRX set may include a DRX received by the terminal device and corresponding to a multicast / multicast service associated with the first cell set / first DRX, a DRX corresponding to a multicast / multicast service in which the terminal device participates and associated with the first cell set / first DRX, or a DRX corresponding to a multicast / multicast service associated with the first cell set / first DRX.

[0411] For example, the second multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX, a multicast / multicast service in which the terminal device joins and associated with the first cell set / first DRX, or a multicast / multicast service associated with the first cell set / first DRX.

[0412] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, namely cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, namely cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1. If the first time is not within the active time of the first DRX group but within the active time of the multicast DRX corresponding to multicast 1, for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 3), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, and the third DRX set is a multicast DRX corresponding to multicast 1, where the first cell set is cell 1, cell 2, and cell 3, the third cell set is cell 2 and cell 3, and the sixth cell set is cell 1.

[0413] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. If the first time is not within the active time of the first DRX group but is within the active time of the multicast DRX corresponding to multicast 1 and the active time of the multicast DRX corresponding to multicast 2, for cells other than both cell 1 and cell 2 in the first cell set (i.e., cell 3), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, the third DRX set is the multicast DRX corresponding to multicast 1 and the multicast DRX corresponding to multicast 2, the first cell set is cell 1, cell 2, and cell 3, the third cell set is cell 3, and the sixth cell set is cell 1 and cell 2.

[0414] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, the terminal device receives multicast 2 in cell 2, and the terminal device receives multicast 4 in cell 4. If the first time is not within the active time of the first DRX group but is within the active time of the multicast DRX corresponding to multicast 1, for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 3), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, and the third DRX set is a multicast DRX corresponding to multicast 1, where the first cell set is cell 1, cell 2, and cell 3, the third cell set is cell 2 and cell 3, and the sixth cell set is cell 1.

[0415] In some embodiments, whether the first time period belongs to the active time period of the third DRX set may be determined by the terminal device.

[0416] Optionally, the first time period belonging to the active time of the third DRX set includes: the terminal device determining that the first time period belongs to the active time of the third DRX set.

[0417] Optionally, the terminal device determining that the first time belongs to an active time of a third DRX set may include:

[0418] (1) the terminal device determines that the first time belongs to an active time of the third DRX set based on or by taking into account any one or more of an assignment (e.g., a received multicast-related assignment) received at and / or before the fourth time, a multicast-related DRX command MAC CE, or a multicast-related long DRX command MAC CE; and / or (2) The terminal device may determine that the first time does not belong to the active time of the second DRX set based on or by taking into account any one or more of an assignment (e.g., a received multicast-related assignment), a multicast-related DRX command MAC CE, or a multicast-related long DRX command MAC CE received at and / or before the fourth time, where the received assignment (e.g., a received multicast-related assignment) may be an assignment received in the sixth cell set or the first cell set, and / or an assignment received related to the second multicast service set, optionally, the multicast-related DRX command MAC CE may be a multicast-related DRX command MAC CE received in the sixth cell set or the first cell set, and / or a DRX command MAC CE related to the second multicast service set, and optionally, the multicast-related long DRX command MAC CE may be a multicast-related long DRX command MAC CE received in the sixth cell set or the first cell set, and / or a long DRX command MAC CE related to the second multicast service set.

[0419] The fourth time period is determined based on the first time period and the third duration.

[0420] For example, the interval between a fourth time and a first time is a third duration, with the fourth time occurring before the first time.

[0421] Similarly, the third duration may be a parameter set by the network device, may be calculated based on a formula or algorithm, or may be specified in a protocol, which is not limited in this embodiment of the present application. For example, the third duration is 4 ms.

[0422] It should be noted that the fourth time and the second time may be the same or different, which is not limited in this embodiment of the present application.

[0423] It should be noted that the third duration and the first duration may be the same or different, which is not limited in this embodiment of the present application.

[0424] Optionally, the first time not belonging to the active time of the first DRX set and the first time belonging to the active time of the third DRX set includes the terminal device determining that the first time does not belong to the active time of the first DRX set and determining that the first time belongs to the active time of the third DRX set.

[0425] Optionally, the terminal device determining that the first time does not belong to the active time of the first DRX set and determining that the first time belongs to the active time of the third DRX set may include:

[0426] (1) The terminal device may determine that the first time does not belong to the active time of the first DRX set and that the first time belongs to the active time of the third DRX set by based on or taking into account any one or more of a grant, an allocation, a DRX command MAC CE, a long DRX command MAC CE, a multicast-related DRX command MAC CE, or a multicast-related long DRX command MAC CE received at and / or before the sixth time, and / or by based on or taking into account a scheduling request transmitted at and / or before the sixth time; and / or (2) The terminal device may determine that the first time does not belong to the active time of the first DRX set and that the first time does not belong to the active time of the third DRX set based on or by taking into account any one or more of a grant, allocation, DRX command MAC CE, long DRX command MAC CE, multicast-related DRX command MAC CE, or multicast-related long DRX command MAC CE received at and / or before the sixth time, and / or based on or by taking into account a scheduling request transmitted at and / or before the sixth time, where the received grant and allocation may be a grant and allocation received in the first cell set or the sixth cell set.

[0427] Optionally, the grant includes a unicast related grant.

[0428] Optionally, the allocations include unicast related allocations and / or multicast related allocations.

[0429] Optionally, the DRX command MAC CE includes a unicast related DRX command MAC CE.

[0430] Optionally, the long DRX command MAC CE includes a long DRX command MAC CE associated with a unicast.

[0431] Optionally, the scheduling request comprises a unicast related scheduling request.

[0432] The sixth time period is determined based on the first time period and the fifth duration.

[0433] For example, the interval between the sixth time and the first time is the fifth duration, with the sixth time being before the first time.

[0434] It should be understood that the fifth duration may be a parameter set by the network device, may be calculated based on a formula or algorithm, or may be specified in a protocol, which is not limited in this embodiment of the present application. For example, the fifth duration is 4 ms.

[0435] Optionally, the preset conditions include condition 2, and the first CSI may be replaced with / may include / may be a fourth CSI.

[0436] The 4th CSI is: Semi-persistent CSI, periodic CSI, CSI configured on the physical uplink shared channel PUSCH; Semi-persistent CSI configured on PUSCH, CSI configured on the physical uplink control channel PUCCH; Periodic CSI configured on the PUCCH, or Semi-persistent CSI configured on PUCCH may include any one or more of the following:

[0437] Optionally, the pre-set condition may include condition 2, and "the terminal device skips transmitting the first CSI at the first time" may be replaced with "the terminal device skips transmitting the fourth CSI at the first time."

[0438] Optionally, skipping the terminal device from transmitting the fourth CSI at the first time can include the following: skipping the terminal device from transmitting semi-persistent CSI; skipping, by the terminal device, transmitting periodic CSI; skipping, by the terminal device, transmitting the configured CSI on the PUSCH; The terminal device skips transmitting the configured semi-persistent CSI on the PUSCH; skipping, by the terminal device, transmitting the configured CSI on the PUCCH; skipping, by the terminal device, transmitting periodic CSI configured on the PUCCH; skipping, by the terminal device, transmitting the configured semi-persistent CSI on the PUCCH; skipping, by the terminal device, transmitting CSI on the PUCCH; skipping, by the terminal device, transmitting periodic CSI on the PUCCH; skipping, by the terminal device, transmitting semi-persistent CSI on the PUCCH; skipping, by the terminal device, transmitting CSI on the PUSCH; Skipping the terminal device from transmitting semi-persistent CSI on the PUSCH may include any one or more of the following:

[0439] For example, if condition 2 is satisfied, the terminal device skips transmitting the first CSI or the fourth CSI at the first time.

[0440] For example, if condition 2 is satisfied, for the third cell set, the terminal device skips transmitting the first CSI or the fourth CSI at the first time.

[0441] For example, if symbol n is not within the active time of unicast DRX but is within the active time of multicast DRX, for a cell or set of cells other than the cell associated with the multicast (e.g., the cell associated with the multicast for which symbol n is within the active time of multicast DRX), the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0442] For example, if symbol n is not within the active time of a DRX group but is within the active time of a multicast DRX associated with the DRX group, for a cell or set of cells other than the cell associated with the multicast in the DRX group (e.g. the cell associated with the multicast for which symbol n is within the active time of the multicast DRX), or in a cell or set of cells other than the cell associated with the multicast in the DRX group (e.g. the cell associated with the multicast for which symbol n is within the active time of the multicast DRX), the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0443] Optionally, the third cell set is not associated with the fifth multicast service set.

[0444] The fifth multicast service set includes at least one multicast service, and the at least one multicast service includes a ninth multicast service.

[0445] Multicast DRX is not set for the ninth multicast service.

[0446] For example, the fifth multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0447] For example, the fifth multicast service set may include a multicast / multicast service received by the terminal device and for which multicast DRX is not set, a multicast / multicast service joined by the terminal device and for which multicast DRX is not set, or a multicast / multicast service for which multicast DRX is not set.

[0448] For example, the fifth multicast service set may include any one or more / all multicast / multicast services received by the terminal device and for which multicast DRX is not set, or any one or more / all multicast / multicast services joined by the terminal device and for which multicast DRX is not set.

[0449] For example, the twelfth cell set is associated with the fifth multicast service set.

[0450] The twelfth cell set includes at least one cell.

[0451] For example, the third cell set not being associated with the fifth multicast service set may be understood as the third cell set not being associated with the twelfth cell set.

[0452] For example, the third cell set may be understood as / include a cell / cell set other than the cell / cell set associated with the fifth multicast service set, or a cell / cell set other than the twelfth cell set.

[0453] It should be noted that condition 2 may be replaced by the first time not belonging to the active time of the first DRX. That is, it is not essential that the first time belongs to the active time of the third DRX set. For example, in the case where there is a fifth multicast service set / a twelfth cell set, condition 2 may be that the first time does not belong to the active time of the first DRX. In this way, for / in the cells corresponding to the multicast where DRX is not configured, the UE can report CSI.

[0454] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the first time is neither within the active time of unicast DRX nor within the active time of multicast DRX corresponding to multicast 1, for cells 3 and 1, the terminal device skips transmitting the first CSI at the first time. The first DRX is unicast DRX, the third DRX set is multicast DRX corresponding to multicast 1, the third cell set is cell 3 and cell 1, and the twelfth cell set is cell 2.

[0455] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the first time is not within the active time of unicast DRX but is within the active time of multicast DRX corresponding to multicast 1, for cell 3, the terminal device skips transmitting the first CSI at the first time. The first DRX is unicast DRX, the third DRX set is multicast DRX corresponding to multicast 1, the third cell set is cell 3, the sixth cell set is cell 1, and the twelfth cell set is cell 2.

[0456] For example, if symbol n is not within the active time of unicast DRX, for a cell or set of cells other than the cell associated with the multicast for which multicast DRX is not configured, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0457] For example, if symbol n is not within the active time of unicast DRX but is within the active time of multicast DRX in which the terminal device participates, for cells or cell sets other than both the cell associated with the multicast (e.g., the cell associated with the multicast for which symbol n is within the active time of multicast DRX) and the cell associated with the multicast for which multicast DRX is not set, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0458] Optionally, the fifth multicast service set / twelfth cell set is associated with the first DRX / first cell set.

[0459] For example, the fifth multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX and in which multicast DRX is not set, a multicast / multicast service in which the terminal device participates and associated with the first cell set / first DRX and in which multicast DRX is not set, or a multicast / multicast service associated with the first cell set / first DRX and in which multicast DRX is not set.

[0460] For example, the fifth multicast service set may include any one or more / all multicast / multicast services received by the terminal device and associated with the first cell set / first DRX and for which multicast DRX is not configured, any one or more / all multicast / multicast services joined by the terminal device and associated with the first cell set / first DRX and for which multicast DRX is not configured, or any one or more / all multicast / multicast services associated with the first cell set / first DRX and for which multicast DRX is not configured.

[0461] For example, the association of the 5th multicast service set / 12th cell set with the 1st DRX / 1st cell set may be understood as the cells included in the 12th cell set using the same DRX parameters (e.g., parameters relating to the 1st DRX) and the reception of control information of the cells included in the 12th cell set being controlled by the same DRX (e.g., the 1st DRX).

[0462] Optionally, the first set of cells includes a twelfth set of cells.

[0463] For example, the twelfth cell set is a subset of the first cell set, or the twelfth cell set is equal to the first cell set.

[0464] Optionally, the first set of cells includes a third set of cells and a twelfth set of cells.

[0465] For example, the third cell set and the twelfth cell set are equal to the first cell set.

[0466] For example, the third cell set and the twelfth cell set do not have an intersection set.

[0467] For example, if symbol n is not within the active time of the DRX group, for a cell or set of cells other than the cell associated with the multicast for which multicast DRX is not configured in the DRX group, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0468] Optionally, the first set of cells includes the third set of cells, the sixth set of cells, and the twelfth set of cells. Alternatively, optionally, the first set of cells includes the third set of cells and the union of the sixth set of cells and the twelfth set of cells.

[0469] For example, the third cell set, the sixth cell set, and the twelfth cell set are equal to the first cell set.

[0470] For example, the third cell set and the twelfth cell set do not have an intersection set.

[0471] For example, the third cell set and the union of the sixth cell set and the twelfth cell set have no intersection set.

[0472] It should be noted that the sixth cell set and the twelfth cell set may or may not have an intersection set, and this is not a limitation in the present application.

[0473] It should be noted that the sixth set of cells and the twelfth set of cells may be the same or different, and this is not a limitation in this application.

[0474] For example, if symbol n is not within the active time of a DRX group but is within the active time of a multicast DRX that the terminal device joins and is associated with the DRX group, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH and / or the terminal device skips transmitting the CSI on the PUCCH for a cell or cell set other than the cell associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of the multicast DRX) and the cell associated with the multicast for which multicast DRX is not configured in the DRX group. For example, the terminal device includes / has two DRX groups, where the first DRX group corresponds to three cells, i.e. cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, i.e. cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the first time is not within the active time of the first DRX group or within the active time of the multicast DRX corresponding to multicast 1, for cells other than cell 2 in the first cell set (i.e., cell 3 and cell 1), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, the third DRX set is the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, the third cell set is cell 3 and cell 1, and the twelfth cell set is cell 2.

[0475] For example, the terminal device includes / has two DRX groups, the first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the first time is not within the active time of the first DRX group but is within the active time of the multicast DRX corresponding to multicast 1, for cells other than both cell 1 and cell 2 in the first cell set (i.e., cell 3), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, and the third DRX set is the multicast DRX corresponding to multicast 1, where the first cell set is cell 1, cell 2, and cell 3, the third cell set is cell 3, the sixth cell set is cell 1, and the twelfth cell set is cell 2.

[0476] For example, the terminal device includes / has two DRX groups, the first DRX group corresponding to three cells, i.e., cell 1, cell 2, and cell 3, and the second DRX group corresponding to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, the terminal device receives multicast 2 in cell 2, and the terminal device receives multicast 4 in cell 4. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the first time is not within the active time of the first DRX group but is within the active time of the multicast DRX corresponding to multicast 1, for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 3), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, and the third DRX set is a multicast DRX corresponding to multicast 1, where the first cell set is cell 1, cell 2, and cell 3, the third cell set is cell 2 and cell 3, the sixth cell set is cell 1, and the twelfth cell set is cell 1.

[0477] For example, for a cell set or cell other than the third cell set (e.g., the sixth cell set and / or the twelfth cell set), the terminal device may transmit the first CSI or CSI at the first time. For example, in a cell or cell set associated with the fifth multicast service set, the terminal device may transmit the first CSI at the first time. Alternatively, in a cell or cell set associated with the ninth multicast service set, the terminal device may transmit the first CSI at the first time.

[0478] In this embodiment of the present application, when a multicast DRC is not set in a multicast in which a terminal device participates, the terminal device may report CSI, so that the base station can obtain CSI, which helps the base station perform multicast scheduling.

[0479] Optionally, the preset conditions include condition 2, and the preset conditions may further include condition 5.

[0480] Optionally, the pre-set conditions may include condition 2, and the method 400 of the present application may further include condition 5 being satisfied.

[0481] For example, if condition 2 and condition 5 are satisfied, the terminal device skips transmitting the first CSI or the fourth CSI at the first time.

[0482] For example, if condition 2 and condition 5 are satisfied, for the third cell set, the terminal device skips transmitting the first CSI or the fourth CSI at the first time.

[0483] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of an on-duration timer corresponding to unicast, or the on-duration timer corresponding to unicast is started or restarted and symbol n is not within the active time of unicast DRX but is within the active time of multicast DRX, then for cells or cell sets other than one or both of the cells associated with multicast (e.g., the cells associated with multicast for which symbol n is within the active time of multicast DRX) and / or the cells associated with multicast for which multicast DRX is not configured, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0484] For example, if DCP is not configured for the terminal device, and symbol n is not within the duration of an on-duration timer corresponding to unicast, or an on-duration timer corresponding to unicast is started or restarted, and symbol n is not within the active time of a DRX group but is within the active time of a multicast DRX associated with the DRX group, for a cell or cell set other than one or both of the cells associated with the multicast (e.g., the cells associated with the multicast for which symbol n is within the active time of the multicast DRX) and / or the cells associated with the multicast for which multicast DRX is not configured in the DRX group, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH. Optionally, the preset condition may include condition 2, and the first CSI may be replaced with / may include / may be the fifth CSI.

[0485] The 5th CSI is: Semi-persistent CSI, CSI configured on PUSCH, Semi-persistent CSI configured on PUCCH, CSI, which is Layer 1 reference signal received power L1-RSRP; CSI without L1-RSRP, Periodic CSI, which is L1-RSRP; Periodic CSI without L1-RSRP CSI, which is configured on PUCCH and is L1-RSRP, CSI configured on PUCCH and not L1-RSRP, Periodic CSI configured on the PUCCH and L1-RSRP; or Periodic CSI configured on PUCCH and not L1-RSRP may include any one or more of the following:

[0486] Optionally, the pre-set condition may include condition 2, and "the terminal device skips transmitting the first CSI at the first time" may be replaced with "the terminal device skips transmitting the fifth CSI at the first time."

[0487] Optionally, skipping the terminal device from transmitting the fifth CSI at the first time can include the following: skipping the terminal device from transmitting semi-persistent CSI; skipping, by the terminal device, transmitting the configured CSI on the PUSCH; skipping, by the terminal device, transmitting the configured semi-persistent CSI on the PUCCH; The terminal device skips transmitting CSI that is L1-RSRP; skipping, by the terminal device, transmitting non-L1-RSRP CSI; The terminal device skips transmitting periodic CSI that is L1-RSRP; The terminal device skips transmitting non-L1-RSRP periodic CSI; The terminal device skips transmitting CSI that is configured on the PUCCH and is L1-RSRP; The terminal device skips transmitting CSI that is configured on the PUCCH and is not L1-RSRP; The terminal device skips transmitting periodic CSI that is configured on the PUCCH and is L1-RSRP; The terminal device skips transmitting periodic CSI that is configured on the PUCCH and is not L1-RSRP; The terminal device skips transmitting CSI, which is L1-RSRP, on a PUCCH; The terminal device skips transmitting non-L1-RSRP CSI on the PUCCH; The terminal device skips transmitting periodic CSI, which is L1-RSRP, on the PUCCH; or The terminal device skips transmitting non-L1-RSRP periodic CSI on the PUCCH. may include any one or more of the following:

[0488] Optionally, the preset conditions include condition 2, and the preset conditions may further include condition 6.

[0489] Optionally, the preset conditions include condition 2, and the method may further include condition 6 being satisfied.

[0490] For example, if condition 2 and condition 6 are satisfied, the terminal device skips transmitting the first CSI or the fifth CSI at the first time.

[0491] For example, if condition 2 and condition 6 are satisfied, for the third cell set, the terminal device skips transmitting the first CSI or the fifth CSI at the first time.

[0492] For example, if DCP is configured for a terminal device, symbol n is within the duration of the on-duration timer corresponding to unicast, the on-duration timer corresponding to unicast is not started or restarted, and symbol n is not within the active time of unicast DRX but is within the active time of multicast DRX, then for cells or cell sets other than one or both of the cells associated with multicast (e.g., the cells associated with multicast for which symbol n is within the active time of multicast DRX) and / or the cells associated with multicast for which multicast DRX is not configured, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI / periodic CSI on the PUCCH.

[0493] For example, if DCP is configured for the terminal device, and symbol n is within the duration of the on-duration timer corresponding to unicast, and the on-duration timer corresponding to unicast is not started or restarted, and symbol n is not within the active time of the DRX group but is within the active time of multicast DRX, for a cell or cell set other than one or both of the cell associated with the multicast (e.g., the cell associated with the multicast for which symbol n is within the active time of multicast DRX) and / or the cell associated with the multicast for which multicast DRX is not configured in the DRX group, or in a cell or cell set other than one or both of the cell associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of multicast DRX) and / or the cell associated with the multicast for which multicast DRX is not configured in the DRX group, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH and / or the terminal device skips transmitting CSI / periodic CSI on the PUCCH. Optionally, the preset condition includes condition 1, and the preset condition may further include condition 7.

[0494] Optionally, the preset conditions include condition 2, and the method may further include condition 7 being satisfied.

[0495] For example, if condition 2 and condition 7 are satisfied, the terminal device skips transmitting the first CSI or the fifth CSI at the first time.

[0496] For example, if condition 2 and condition 7 are satisfied, for the third cell set, the terminal device skips transmitting the first CSI or the fifth CSI at the first time.

[0497] For example, if condition 2, condition 6, and condition 7 are satisfied, the terminal device skips transmitting the first CSI or the fifth CSI at the first time.

[0498] For example, if condition 2, condition 6, and condition 7 are satisfied, for the third cell set, the terminal device skips transmitting the first CSI or the fifth CSI at the first time.

[0499] For example, if DCP is configured for a terminal device, and symbol n is within the duration of the on-duration timer corresponding to unicast, and the on-duration timer corresponding to unicast is not started or restarted, and symbol n is not within the active time of unicast DRX but is within the active time of multicast DRX, then for cells or cell sets other than one or both of the cells associated with multicast (e.g. the cells associated with multicast for which symbol n is within the active time of multicast DRX) and / or the cells associated with multicast for which multicast DRX is not configured, the terminal device shall: skipping, by the terminal device, transmitting semi-persistent CSI configured on a PUSCH; If the terminal device is not configured to need to report L1-RSRP periodic CSI or L1-RSRP CSI, the terminal device skips transmitting L1-RSRP periodic CSI on the PUCCH; or If the terminal device is not configured to need to report non-L1-RSRP periodic CSI or non-L1-RSRP CSI, the terminal device may skip transmitting non-L1-RSRP periodic CSI on the PUCCH. Execute one or more of the following:

[0500] For example, if DCP is configured for a terminal device, and symbol n is within the duration of the on-duration timer corresponding to unicast, and the on-duration timer corresponding to unicast is not started or restarted, and symbol n is neither within the active time of the DRX group nor within the active time of the multicast DRX, then for a cell or set of cells other than one or both of the cells associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of the multicast DRX) and / or the cells associated with the multicast for which multicast DRX is not configured within the DRX group, or in a cell or set of cells other than one or both of the cells associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of the multicast DRX) and / or the cells associated with the multicast for which multicast DRX is not configured within the DRX group, the terminal device shall skipping, by the terminal device, transmitting semi-persistent CSI configured on a PUSCH; If the terminal device is not configured to need to report L1-RSRP periodic CSI or L1-RSRP CSI, the terminal device skips transmitting L1-RSRP periodic CSI on the PUCCH; or If the terminal device is not configured to need to report non-L1-RSRP periodic CSI or non-L1-RSRP CSI, the terminal device may skip transmitting non-L1-RSRP periodic CSI on the PUCCH. Execute one or more of the following:

[0501] Condition 3: Neither the first nor the second timer is operating during the first time.

[0502] During the operation of the first timer, the terminal device monitors control information specific to the terminal device.

[0503] It should be noted that during the operation of the first timer, the terminal device may alternatively monitor control information that is not specific to the terminal device, which is not limited in this application.

[0504] For example, while the first timer is running, the terminal device may monitor the scrambled control information by using any one or more of the following RNTIs: C-RNTI, CI-RNTI, CS-RNTI, INT-RNTI, SFI-RNTI, SP-CSI-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, TPC-SRS-RNTI, AI-RNTI, SL-RNTI, SLCS-RNTI, or SL Semi-Persistent Scheduling V-RNTI.

[0505] For example, the first timer may be associated with a first DRX.

[0506] For example, the first timer may be associated with unicast.

[0507] For example, the first timer may be an on duration timer (eg, drx-onDurationTimer), an on duration timer for unicast DRX (eg, drx-onDurationTimer), or an on duration timer for a DRX group (eg, drx-onDurationTimer).

[0508] For example, the on-duration timer indicates the time that the terminal device waits to receive control information (eg, DCI) after being woken up.

[0509] The second set of timers includes at least one multicast timer, and the at least one multicast timer includes a third multicast timer, and during the operation of the third multicast timer, the terminal device monitors control information related to the third multicast service.

[0510] For example, the multicast timer may be an on duration timer corresponding to multicast (eg, drx-onDurationTimerPTM) or an on duration timer for multicast DRX (eg, drx-onDurationTimerPTM).

[0511] For example, the second set of timers may include a multicast timer corresponding to a multicast / multicast service received by the terminal device or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins.

[0512] For example, the second timer set may include a multicast timer corresponding to any multicast / multicast service / all multicast / multicast services received by the terminal device, or a multicast timer corresponding to any multicast / multicast service / all multicast / multicast services in which the terminal device participates.

[0513] For example, the second timer set may be associated with a third multicast service set, and the third multicast service set may include a third multicast service.

[0514] For example, the third multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0515] For example, the third multicast service set may include any multicast / multicast services / all multicast / multicast services received by the terminal device, or any multicast / multicast services / all multicast / multicast services in which the terminal device participates.

[0516] For example, the third multicast service may be understood as a multicast service associated with the 3G-RNTI and / or the 3G-CS-RNTI, or a multicast associated with the 3G-RNTI and / or the 3G-CS-RNTI.

[0517] For example, control information relating to the third multicast service may include / be understood as control information associated with (or scrambled by using) the 3G-RNTI and / or the 3G-CS-RNTI, and / or control information scrambled by using a unicast RNTI (e.g., a C-RNTI and / or a CS-RNTI).

[0518] It should be noted that during the operation of the third multicast timer, the terminal device may alternatively monitor other control information, which is not limited in this application.

[0519] For example, the third multicast timer may be a timer for the third multicast service, a drx-onDurationTimerPTM for the third multicast service, a timer for the 3G-RNTI and / or the 3G-CS-RNTI, or a drx-onDurationTimerPTM for the 3G-RNTI and / or the 3G-CS-RNTI.

[0520] Optionally, the preset condition may include condition 3, and "the terminal device skips transmitting the first CSI at the first time" may include, for the first cell set, the terminal device skipping transmitting the first CSI at the first time.

[0521] The first cell set includes at least one cell, and the first cell set is associated with a first DRX or a first timer.

[0522] For example, the first timer is an on-duration timer (eg, drx-onDurationTimer) corresponding to a DRX group (eg, a first DRX group).

[0523] It should be understood that for the relevant description of "for the first cell set, the terminal device skips transmitting the first CSI at the first time", reference should be made to the above relevant description. For the sake of brevity, the details will not be described again.

[0524] Optionally, the first set of cells includes a fourth set of cells.

[0525] For example, the fourth set of cells may be a subset of the first set of cells, or the fourth set of cells may be equal to the first set of cells.

[0526] A fourth cell set is associated with the second timer set, the fourth cell set including at least one cell.

[0527] It can be understood that the second timer set is associated with the first timer.

[0528] For example, the second timer set may include a multicast timer corresponding to a multicast / multicast service received by the terminal device and associated with the first cell set / first timer / first DRX, a multicast timer corresponding to a multicast / multicast service in which the terminal device participates and associated with the first cell set / first timer / first DRX, or a multicast timer corresponding to a multicast / multicast service associated with the first cell set / first timer / first DRX.

[0529] For example, the second timer set may include a multicast timer corresponding to any multicast / multicast service / all multicast / multicast services received by the terminal device and associated with the first cell set / first timer / first DRX, a multicast timer corresponding to any multicast / multicast service / all multicast / multicast services in which the terminal device participates and associated with the first cell set / first timer / first DRX, or a multicast timer corresponding to any multicast / multicast service / all multicast / multicast services associated with the first cell set / first timer / first DRX.

[0530] For example, the third multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first timer / first DRX, a multicast / multicast service in which the terminal device participates and associated with the first cell set / first timer / first DRX, or a multicast / multicast service associated with the first cell set / first timer / first DRX.

[0531] For example, the third multicast service set may include any multicast / multicast service / all multicast / multicast services received by the terminal device and associated with the first cell set / first timer / first DRX, any multicast / multicast service / all multicast / multicast services in which the terminal device participates and associated with the first cell set / first timer / first DRX, or any multicast / multicast service / all multicast / multicast services associated with the first cell set / first timer / first DRX.

[0532] For example, the second timer set is a multicast timer set associated with the first timer or the first DRX, or a multicast timer set corresponding to a multicast service set associated with the first cell set.

[0533] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1. If neither the timer of the first DRX group nor the timer of the multicast DRX corresponding to multicast 1 is running at a first time, for the first DRX group / first cell set, the terminal device skips transmitting a first CSI at a first time. The first timer is the timer of the first DRX group, and the second timer set is the timer of the multicast DRX corresponding to multicast 1, where the first cell set is cell 1, cell 2, and cell 3, and the fourth cell set is cell 1.

[0534] For example, a terminal device includes / has two DRX groups, a first DRX group corresponding to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponding to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. If neither the timer of the first DRX group nor the timer of the multicast DRX corresponding to multicast 1 and the timer of the multicast DRX corresponding to multicast 2 are running at the first time, for the first DRX group / first cell set, the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the second timer set is the timer of the multicast DRX corresponding to multicast 1 and the timer of the multicast DRX corresponding to multicast 2, the first cell set is cell 1, cell 2, and cell 3, and the fourth cell set is cell 1 and cell 2.

[0535] For example, a terminal device includes / has two DRX groups, a first DRX group corresponding to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponding to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, the terminal device receives multicast 2 in cell 2, and the terminal device receives multicast 4 in cell 4. If neither the timer of the first DRX group nor the timer of the multicast DRX corresponding to multicast 1 and the timer of the multicast DRX corresponding to multicast 2 are running at the first time, for the first DRX group / first cell set, the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the second timer set is the timer of the multicast DRX corresponding to multicast 1 and the timer of the multicast DRX corresponding to multicast 2, the first cell set is cell 1, cell 2, and cell 3, and the fourth cell set is cell 1 and cell 2.

[0536] In some embodiments, whether the first timer is running at the first time may be determined by the terminal device.

[0537] Optionally, the first timer not running may include the terminal device determining that the first timer is not running.

[0538] Optionally, the terminal device determining that the first timer is not running may include:

[0539] (1) the terminal device may determine that the first timer is not running based on or by taking into account any one or more of a grant, an assignment, a DRX command MAC CE, or a long DRX command MAC CE received at and / or before the seventh hour, and / or based on or by taking into account a scheduling request transmitted at and / or before the seventh hour; and / or (2) The terminal device may determine that the first timer is not running based on or by taking into account any one or more of a grant, assignment, DRX command MAC CE, or long DRX command MAC CE received at and / or before the seventh time, and / or based on or by taking into account a scheduling request transmitted at and / or before the seventh time, where the received grant and assignment may be a grant and assignment received in the first cell set.

[0544] Optionally, the scheduling request comprises a unicast related scheduling request.

[0545] The seventh time is determined based on the first time and the sixth duration.

[0546] For example, the interval between the seventh time and the first time is the sixth duration, with the seventh time being before the first time.

[0547] For example, the sixth duration may be a parameter set by the network device, may be calculated based on a formula or algorithm, or may be specified in a protocol, which is not limited in this embodiment of the present application. For example, the sixth duration is 4 ms.

[0548] In some embodiments, whether the second timer set is running at the first time may be determined by the terminal device.

[0549] Optionally, the second timer set not being activated includes the terminal device determining that the second timer set is not activated.

[0550] Optionally, the terminal device determining that the second timer set is not activated may include:

[0552] The eighth time period is determined based on the first time period and the seventh duration.

[0553] For example, the interval between the eighth time and the first time is the seventh duration, with the eighth time being before the first time.

[0554] It should be understood that the seventh duration may be a parameter set by the network device, may be calculated based on a formula or algorithm, or may be specified in a protocol, which is not limited in this embodiment of the present application. For example, the seventh duration is 4 ms.

[0561] Optionally, the scheduling request comprises a unicast related scheduling request.

[0562] The ninth hour is determined based on the first hour and the eighth duration.

[0563] For example, the interval between the 9th time and the 1st time is the 8th duration, with the 9th time being before the 1st time.

[0564] For example, the eighth duration may be a parameter set by the network device, may be calculated based on a formula or algorithm, or may be specified in a protocol, which is not limited in this embodiment of the present application. For example, the eighth duration is 4 ms.

[0565] Optionally, the preset conditions include condition 3, and the first CSI may be replaced with / may include / may be the sixth CSI.

[0566] The 6th CSI is: Semi-persistent CSI, periodic CSI, CSI configured on the physical uplink shared channel PUSCH; Semi-persistent CSI configured on PUSCH, CSI configured on the physical uplink control channel PUCCH; Periodic CSI configured on the PUCCH, or Semi-persistent CSI configured on PUCCH may include any one or more of the following:

[0569] For example, if condition 3 is satisfied, the terminal device skips transmitting the first CSI or the sixth CSI at the first time.

[0570] For example, if condition 3 is satisfied, for the first cell set, the terminal device skips transmitting the first CSI or the sixth CSI at the first time.

[0571] For example, if neither the on-duration timer corresponding to unicast nor the on-duration timer corresponding to multicast is running at symbol n, the terminal device skips transmitting CSI on the PUCCH.

[0572] For example, if neither the on-duration timer corresponding to the DRX group unicast nor the on-duration timer corresponding to the multicast associated with the DRX group is running at symbol n, the terminal device skips transmitting CSI on the PUCCH.

[0573] Optionally, the preset conditions include condition 3, and the preset conditions may further include condition 5.

[0576] For example, if condition 3 and condition 5 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI or the sixth CSI at the first time.

[0577] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of the on-duration timer corresponding to unicast, or the on-duration timer corresponding to unicast is started or restarted and neither the on-duration timer corresponding to unicast nor the on-duration timer corresponding to multicast is running at symbol n, the terminal device skips transmitting CSI on the PUCCH.

[0578] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of the on-duration timer corresponding to a unicast, or the on-duration timer corresponding to a unicast is started or restarted and neither the on-duration timer corresponding to the DRX group nor the on-duration timer corresponding to a multicast associated with the DRX group is running at symbol n, then the terminal device skips transmitting CSI on the PUCCH for or within the DRX group.

[0580] Optionally, the pre-set conditions may include condition 3, and the method 400 of the present application may further include condition 8 being satisfied.

[0581] Condition 8 may include that the terminal device obtains the first information.

[0582] The first piece of information is: The terminal device should transmit CSI during the operation of a unicast timer (e.g., a first timer) and / or during the operation of a multicast timer; The terminal device should be limited to transmitting CSI while a unicast timer (e.g., a first timer) is running and / or while a multicast timer is running, or That the terminal device should transmit CSI only while the unicast timer (e.g., the first timer) is running and / or while the multicast timer is running. It may indicate any one or more of the following:

[0583] For example, the unicast timer may include / be an on duration timer corresponding to the unicast (eg, drx-onDurationTimer) and / or an on duration timer corresponding to the DRX group (eg, drx-onDurationTimer).

[0584] "Transmitting CSI while a unicast timer (e.g., the first timer) is running and / or while a multicast timer is running" may include / be understood as any one or more of the following: transmitting CSI on a PUCCH while a unicast timer (e.g., the first timer) is running and / or while a multicast timer is running.

[0585] For example, the first information may be transmitted by a network device. For example, the network device may transmit the first information to the terminal device by using an RRC message.

[0586] For example, the first information may be CSI mask information (also referred to as CSI masking information or CSI-masking information). The CSI mask information may instruct the terminal device to transmit CSI during the operation of drx-onDurationTimer and / or during the operation of drx-onDurationTimerPTM.

[0587] Therefore, when the terminal device acquires the first information, during an active time other than both / one of the operating periods of the unicast timer and / or the multicast timer, or during a time other than both / one of the operating periods of the unicast timer and / or the multicast timer, the terminal device skips transmitting CSI, or the terminal device skips transmitting CSI on the PUCCH.

[0588] It should be noted that "the terminal device acquires the first information" may include / be replaced with a CSI mask being set for the terminal device.

[0589] It should be noted that "the terminal device does not acquire the first information" may include / be replaced with that the CSI mask is not set for the terminal device.

[0590] For example, if condition 3 and condition 8 are satisfied, the terminal device skips transmitting the first CSI or the sixth CSI at the first time.

[0591] For example, if condition 3 and condition 8 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI or the sixth CSI at the first time.

[0592] For example, if CSI masking is configured for a terminal device and neither the on-duration timer corresponding to unicast nor the on-duration timer corresponding to multicast is running at symbol n, the terminal device skips transmitting CSI on the PUCCH.

[0593] For example, if CSI masking is configured for a terminal device and neither the on-duration timer corresponding to the DRX group nor the on-duration timer corresponding to the multicast associated with the DRX group is running at symbol n, then the terminal device skips transmitting CSI on the PUCCH for or within the DRX group.

[0594] For example, if condition 3, condition 5, and condition 8 are satisfied, the terminal device skips transmitting the first CSI or the sixth CSI at the first time.

[0595] For example, if condition 3, condition 5, and condition 8 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI or the sixth CSI at the first time.

[0596] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of the on-duration timer corresponding to unicast, or the on-duration timer corresponding to unicast is started or restarted, and CSI masking is configured for the terminal device and neither the on-duration timer corresponding to unicast nor the on-duration timer corresponding to multicast is running at symbol n, the terminal device skips transmitting CSI on the PUCCH.

[0597] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of the on-duration timer corresponding to unicast, or the on-duration timer corresponding to unicast is started or restarted, and CSI masking is configured for the terminal device and neither the on-duration timer corresponding to the DRX group nor the on-duration timer corresponding to the multicast associated with the DRX group is running at symbol n, then the terminal device skips transmitting CSI on the PUCCH for or within the DRX group.

[0598] Condition 4: The first timer is not running at the first time, but the third timer set is running.

[0599] The third set of timers includes at least one multicast timer, and the at least one multicast timer includes a fourth multicast timer, and during operation of the fourth multicast timer, the terminal device may monitor control information related to the fourth multicast service.

[0600] For example, the third set of timers may include a multicast timer corresponding to a multicast / multicast service received by the terminal device or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins.

[0601] For example, the third timer set may be associated with a fourth multicast service set, and the fourth multicast service set may include a fourth multicast service.

[0602] For example, the fourth multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0603] For example, the fourth multicast service may be understood as a multicast service associated with the 4G-RNTI and / or the 4G-CS-RNTI, or a multicast associated with the 4G-RNTI and / or the 4G-CS-RNTI.

[0604] For example, control information regarding the fourth multicast service may include / be understood as control information associated with (or scrambled by using) the 4G-RNTI and / or the 4G-CS-RNTI, and / or control information scrambled by using a unicast RNTI (e.g., a C-RNTI and / or a CS-RNTI).

[0605] It should be noted that during the operation of the fourth multicast timer, the terminal device may alternatively monitor other control information, which is not limited in this application.

[0606] For example, the fourth multicast timer may be a timer for the fourth multicast service, a drx-onDurationTimerPTM for the fourth multicast service, a timer for the 4G-RNTI and / or the 4G-CS-RNTI, or a drx-onDurationTimerPTM for the 4G-RNTI and / or the 4G-CS-RNTI.

[0607] Optionally, the pre-set condition may include condition 4, where "the terminal device transmits the first CSI at the first time" may include, for the fifth cell set, skipping the terminal device from transmitting the first CSI at the first time.

[0608] The fifth cell set includes at least one cell, and the fifth cell set is not associated with the third timer set.

[0609] "For the fifth cell set, the terminal device skips transmitting the first CSI at the first time" as follows: the terminal device skipping transmitting CSI (e.g., the first CSI) in the fifth cell set at the first time; or The terminal device skips transmitting CSI (e.g., the first CSI) specific to the fifth cell set at the first time. It should be noted that the term "a" may include / be understood as any one of the following:

[0610] It should be noted that when "the terminal device skips transmitting CSI (e.g., the first CSI) in the fifth cell set at the first time," whether the terminal device transmits CSI specific to the fifth cell set in another cell or cell group is not limited in this application.

[0611] It should be noted that when "the terminal device transmits CSI (e.g., the first CSI) specific to the fifth cell set at the first time," whether the terminal device transmits CSI specific to another cell or cell set within the fifth cell set is not limited in this application.

[0612] For example, the seventh cell set is associated with the third timer cell or the fourth multicast service set.

[0613] The seventh cell set includes at least one cell.

[0614] It should be appreciated that the fifth cell set not being associated with the third timer set may be understood as the fifth cell set not being associated with the fourth multiservice set.

[0615] For example, the fifth cell set may be understood as / include a cell / cell set other than the cell / cell set associated with the fourth multicast service set, or a cell / cell set other than the seventh cell set.

[0616] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1. If, at a first time, an on-duration timer corresponding to unicast is not running but an on-duration timer corresponding to multicast 1 is running, then for cells 2 and 3, the terminal device skips transmitting a first CSI at the first time. The first timer is an on-duration timer corresponding to unicast, the third timer set is an on-duration timer corresponding to multicast 1, the fifth cell set is cell 2 and cell 3, and the seventh cell set is cell 1.

[0617] Optionally, the fifth cell set is associated with the first timer or the first DRX.

[0618] For example, the association of a fifth cell set with a first timer or a first DRX may be understood as cells in the fifth cell set using the same DRX parameters (e.g., parameters relating to the first timer or the first DRX) and reception of control information of cells included in the fifth cell set being controlled by the same DRX (e.g., the first timer or the first DRX).

[0619] Optionally, the seventh cell set is associated with the first DRX.

[0620] For example, the association of a seventh cell set with the first DRX may be understood as the cells included in the seventh cell set using the same DRX parameters (e.g., parameters relating to the first DRX) and the reception of control information of the cells included in the seventh cell set being controlled by the same DRX (e.g., the first DRX).

[0621] Optionally, the first set of cells includes a fifth set of cells.

[0622] For example, the fifth cell set is a subset of the first cell set, or the fifth cell set is equal to the first cell set.

[0623] For example, the first cell set includes the seventh cell set.

[0624] For example, the seventh cell set is a subset of the first cell set, or the seventh cell set is equal to the first cell set.

[0625] Optionally, the first set of cells includes a fifth set of cells and a seventh set of cells.

[0626] For example, the fifth and seventh cell sets are equal to the first cell set.

[0627] For example, the fifth cell set and the seventh cell set do not have an intersection set.

[0628] For example, the third timer set may include a multicast timer corresponding to a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX / first timer, a multicast timer corresponding to a multicast / multicast service in which the terminal device participates and associated with the first cell set / first DRX / first timer, or a multicast timer corresponding to a multicast / multicast service associated with the first cell set / first DRX / first timer.

[0629] For example, the fourth multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX / first timer, a multicast / multicast service in which the terminal device participates and associated with the first cell set / first DRX / first timer, or a multicast / multicast service associated with the first cell set / first DRX / first timer.

[0630] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1. If, at a first time, the on-duration timer of the first DRX group is not running but the on-duration timer of the multicast DRX corresponding to multicast 1 is running, for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 3), the terminal device skips transmitting the first CSI at the first time. The first timer is the on-duration timer of the first DRX group, and the third timer set is the on-duration timer of the multicast DRX corresponding to multicast 1, where the first cell set is cell 1, cell 2, and cell 3, and the fifth cell set is cell 2 and cell 3.

[0631] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. If, at a first time, the on-duration timer of the first DRX group is not running, but the on-duration timer of the multicast DRX corresponding to multicast 1 and the on-duration timer of the multicast DRX corresponding to multicast 2 are running, for cells other than both cell 1 and cell 2 in the first cell set (i.e., cell 3), the terminal device skips transmitting the first CSI at the first time. The first timer is the on-duration timer of the first DRX group, and the third timer set is the on-duration timer of the multicast DRX corresponding to multicast 1 and the on-duration timer of the multicast DRX corresponding to multicast 2, where the first cell set is cell 1, cell 2, and cell 3, and the fifth cell set is cell 3.

[0632] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, the terminal device receives multicast 2 in cell 2, and the terminal device receives multicast 4 in cell 4. If, at a first time, the on-duration timer of the first DRX group is not running but the on-duration timer of the multicast DRX corresponding to multicast 1 is running, then for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 3), the terminal device skips transmitting the first CSI at the first time. The first timer is the on-duration timer of the first DRX group, and the third timer set is the on-duration timer of the multicast DRX corresponding to multicast 1, where the first cell set is cell 1, cell 2, and cell 3, and the fifth cell set is cell 2 and cell 3.

[0633] In some embodiments, it may be determined by the terminal device that the third timer set is running at the first time.

[0634] Optionally, the third timer set running includes the terminal device determining that the third timer set is running.

[0635] Optionally, the terminal device determining that the third timer set is running may include:

[0636] (1) the terminal device determines that a third timer set is running based on or by taking into account any one or more of an assignment (e.g., a received multicast-related assignment) received at and / or before the tenth hour, a multicast-related DRX command MAC CE, or a multicast-related long DRX command MAC CE; and / or (2) The terminal device may determine that the third timer set is running based on or by taking into account any one or more of an assignment (e.g., a received multicast-related assignment) received at and / or before the tenth time, a multicast-related DRX command MAC CE, or a multicast-related long DRX command MAC CE, where the received assignment (e.g., a received multicast-related assignment) may be an assignment received in the seventh cell set or the first cell set and / or a received assignment related to the fourth multicast service set, optionally, the multicast-related DRX command MAC CE may be a multicast-related DRX command MAC CE received in the seventh cell set or the first cell set and / or a DRX command MAC CE related to the fourth multicast service set, and optionally, the multicast-related long DRX command MAC CE may be a multicast-related long DRX command MAC CE received in the seventh cell set or the first cell set and / or a long DRX command MAC CE related to the fourth multicast service set.

[0637] The tenth time is determined based on the first time and the ninth duration.

[0638] For example, the interval between the 10th time and the 1st time is the 9th duration, with the 10th time occurring before the 1st time.

[0639] It should be understood that the tenth duration may be a parameter set by the network device, may be calculated based on a formula or algorithm, or may be specified in a protocol, which is not limited in this embodiment of the present application. For example, the tenth duration is 4 ms.

[0640] Optionally, determining that the first timer is not running but the third timer set is running at the first time includes the terminal device determining that the first timer is not running but the third timer set is running.

[0641] Optionally, the terminal device determining that the first timer is not running but the third timer set is running may include:

[0642] (1) the terminal device may determine that the first timer is not running but the third timer set is running based on or by taking into account any one or more of a grant, an assignment, a DRX command MAC CE, a long DRX command MAC CE, a multicast-related DRX command MAC CE, or a multicast-related long DRX command MAC CE received at and / or before the eleventh hour, and / or based on or by taking into account a scheduling request transmitted at and / or before the eleventh hour; and / or (2) The terminal device may determine that the first timer is not running but the third timer set is running based on or by taking into account any one or more of a grant, allocation, DRX command MAC CE, long DRX command MAC CE, multicast-related DRX command MAC CE, or multicast-related long DRX command MAC CE received at and / or before the 11th hour, and / or based on or by taking into account a scheduling request transmitted at and / or before the 11th hour, where the received grant and allocation may be a grant and allocation received in the first cell set or the seventh cell set.

[0643] Optionally, the grant includes a unicast related grant.

[0644] Optionally, the allocations include unicast related allocations and / or multicast related allocations.

[0645] Optionally, the DRX command MAC CE includes a unicast related DRX command MAC CE.

[0646] Optionally, the long DRX command MAC CE includes a long DRX command MAC CE associated with a unicast.

[0647] Optionally, the scheduling request comprises a unicast related scheduling request.

[0648] The eleventh time is determined based on the first time and the tenth duration.

[0649] For example, the interval between the 11th time and the 1st time is the 10th duration, with the 11th time being before the 1st time.

[0650] It should be understood that the tenth duration may be a parameter set by the network device, may be calculated based on a formula or algorithm, or may be specified in a protocol, which is not limited in this embodiment of the present application. For example, the tenth duration is 4 ms.

[0651] Optionally, the preset conditions include condition 4, and the first CSI may be replaced with / may include / may be the seventh CSI.

[0652] The 7th CSI is: Semi-persistent CSI, periodic CSI, CSI configured on the physical uplink shared channel PUSCH; Semi-persistent CSI configured on PUSCH, CSI configured on the physical uplink control channel PUCCH; Periodic CSI configured on the PUCCH, or Semi-persistent CSI configured on PUCCH may include any one or more of the following:

[0653] Optionally, the pre-set condition may include condition 4, and "the terminal device skips transmitting the first CSI at the first time" may be replaced with "the terminal device skips transmitting the seventh CSI at the first time."

[0654] Optionally, skipping the terminal device from transmitting the seventh CSI at the first time can include: skipping the terminal device from transmitting semi-persistent CSI; skipping, by the terminal device, transmitting periodic CSI; skipping, by the terminal device, transmitting the configured CSI on the PUSCH; The terminal device skips transmitting the configured semi-persistent CSI on the PUSCH; skipping, by the terminal device, transmitting the configured CSI on the PUCCH; skipping, by the terminal device, transmitting periodic CSI configured on the PUCCH; skipping, by the terminal device, transmitting the configured semi-persistent CSI on the PUCCH; skipping, by the terminal device, transmitting CSI on the PUCCH; skipping, by the terminal device, transmitting periodic CSI on the PUCCH; skipping, by the terminal device, transmitting semi-persistent CSI on the PUCCH; skipping, by the terminal device, transmitting CSI on the PUSCH; Skipping the terminal device from transmitting semi-persistent CSI on the PUSCH may include any one or more of the following:

[0655] For example, if condition 4 is satisfied, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0656] For example, if condition 4 is satisfied, for the fifth cell set, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0657] For example, if, at symbol n, the on-duration timer corresponding to unicast is not running but the on-duration timer corresponding to multicast is running, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than the cell associated with the multicast (e.g., the cell associated with the multicast for which symbol n is within the active time of the multicast DRX).

[0658] For example, if, at symbol n, the on-duration timer corresponding to the DRX group is not running but the on-duration timer corresponding to the multicast associated with the DRX group is running, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than the cells associated with the multicast in the DRX group (e.g. the cells associated with the multicast for which symbol n is within the active time of the multicast DRX) or in cells or cell sets other than the cells associated with the multicast in the DRX group (e.g. the cells associated with the multicast for which symbol n is within the active time of the multicast DRX).

[0659] Optionally, the fifth cell set is not associated with the seventh multicast service set.

[0660] The seventh multicast service set includes at least one multicast service, and the at least one multicast service includes an eleventh multicast service.

[0661] Multicast DRX is not set for the 11th multicast service.

[0662] For example, the seventh multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0663] A multicast / multicast service received by a terminal device may include / be understood as a multicast / multicast service that is / has been / is being received by the terminal device and / or a multicast / multicast service for which the terminal device obtains settings relating to the multicast / multicast service.

[0664] For example, the seventh multicast service set may include a multicast / multicast service received by the terminal device and for which multicast DRX is not set, a multicast / multicast service joined by the terminal device and for which multicast DRX is not set, or a multicast / multicast service for which multicast DRX is not set.

[0665] For example, the seventh multicast service set may include any one or more / all multicast / multicast services received by the terminal device and for which multicast DRX is not set, or any one or more / all multicast / multicast services joined by the terminal device and for which multicast DRX is not set.

[0666] For example, the thirteenth cell set is associated with the seventh multicast service set.

[0667] The thirteenth cell set includes at least one cell.

[0668] For example, the fifth cell set not being associated with the seventh multicast service set may be understood as the fifth cell set not being associated with the thirteenth cell set.

[0669] For example, the fifth cell set may be understood as / include a cell / cell set other than the cell / cell set associated with the seventh multicast service set, or a cell / cell set other than the thirteenth cell set.

[0670] It should be noted that condition 4 may be replaced by the first timer not running. That is, it is not essential that the first time belongs to the active time of the third DRX set. For example, in the case where there is a seventh multicast service set / thirteenth cell set, condition 4 may be that the first timer is not running. In this way, the UE can report CSI for / in the cells corresponding to the multicast where DRX is not configured.

[0671] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If, at a first time, the on-duration timer of the first DRX is not running, and the on-duration timer of the multicast DRX corresponding to multicast 1 is also not running, then for cells 3 and 1, the terminal device skips transmitting the first CSI at the first time. The first DRX is unicast DRX, the third timer set is the on-duration timer of the multicast DRX corresponding to multicast 1, the fifth cell set is cell 3 and cell 1, and the thirteenth cell set is cell 2.

[0672] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If, at a first time, the on-duration timer of the first DRX is not running but the on-duration timer of the multicast DRX corresponding to multicast 1 is running, then for cell 3, the terminal device skips transmitting the first CSI at the first time. The first DRX is unicast DRX, the third timer is the on-duration timer of the multicast DRX corresponding to multicast 1, the fifth cell set is cell 3, the seventh cell set is cell 1, and the thirteenth cell set is cell 2.

[0673] For example, if the on-duration timer corresponding to the unicast is not running at symbol n, for a cell or cell set other than the cell associated with the multicast for which multicast DRX is not set, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0674] For example, if, at symbol n, the on-duration timer corresponding to the unicast is not running but the on-duration timer corresponding to the multicast in which the terminal device participates is running, for cells or cell sets other than both the cell associated with the multicast (e.g., the cell associated with the multicast for which symbol n is within the active time of the multicast DRX) and the cell associated with the multicast for which multicast DRX is not set, the terminal device skips transmitting the semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0675] Optionally, the seventh multicast service set / thirteenth cell set is associated with the first DRX / first cell set.

[0676] For example, the seventh multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX and in which multicast DRX is not set, a multicast / multicast service in which the terminal device participates and associated with the first cell set / first DRX and in which multicast DRX is not set, or a multicast / multicast service associated with the first cell set / first DRX and in which multicast DRX is not set.

[0677] For example, the seventh multicast service set may include any one or more / all multicast / multicast services received by the terminal device and associated with the first cell set / first DRX and for which multicast DRX is not configured, any one or more / all multicast / multicast services joined by the terminal device and associated with the first cell set / first DRX and for which multicast DRX is not configured, or any one or more / all multicast / multicast services associated with the first cell set / first DRX and for which multicast DRX is not configured.

[0678] For example, the association of the 7th multicast service set / 13th cell set with the 1st DRX / 1st cell set may be understood as the cells included in the 13th cell set using the same DRX parameters (e.g., parameters relating to the 1st DRX) and the reception of control information of the cells included in the 13th cell set being controlled by the same DRX (e.g., the 1st DRX).

[0679] Optionally, the first set of cells includes a thirteenth set of cells.

[0680] For example, the thirteenth cell set is a subset of the first cell set, or the thirteenth cell set is equal to the first cell set.

[0681] Optionally, the first set of cells includes a fifth set of cells and a thirteenth set of cells.

[0682] For example, the fifth and thirteenth cell sets are equal to the first cell set.

[0683] For example, the fifth cell set and the thirteenth cell set do not have an intersection set.

[0684] For example, at symbol n, if the on-duration timer corresponding to the DRX group is not running, but the on-duration timer corresponding to the multicast that the terminal device joins and associated with the DRX group is running, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than the cell associated with the multicast for which multicast DRX is not configured in the DRX group.

[0685] Optionally, the first set of cells includes the fifth cell set, the seventh cell set, and the thirteenth cell set. Alternatively, optionally, the first set of cells includes the fifth cell set and the union of the seventh cell set and the thirteenth cell set.

[0686] For example, the fifth cell set, the seventh cell set, and the thirteenth cell set are equal to the first cell set.

[0687] For example, the fifth cell set and the thirteenth cell set do not have an intersection set.

[0688] For example, the fifth cell set and the union of the seventh cell set and the thirteenth cell set have no intersection set.

[0689] It should be noted that the seventh cell set and the thirteenth cell set may or may not have a common subset set, and this is not a limitation in this application.

[0690] It should be noted that the seventh and thirteenth cell sets may be the same or different, and this is not a limitation in this application.

[0691] For example, if, at symbol n, the on-duration timer corresponding to the DRX group is not running but the on-duration timer corresponding to the multicast that the terminal device joins and is associated with the DRX group is running, then for a cell or set of cells other than both the cell associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of the multicast DRX) and the cell associated with the multicast for which multicast DRX is not set in the DRX group, the terminal device skips transmitting the configured semi-persistent CSI on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0692] For example, a terminal device includes / has two DRX groups, a first DRX group corresponding to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponding to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If, at the first time, neither the on-duration timer of the first DRX group nor the on-duration timer of the multicast DRX corresponding to multicast 1 is running, for cells other than cell 2 in the first cell set (i.e., cell 3 and cell 1), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, the third timer set is the on-duration timer of the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, the fifth cell set is cell 3 and cell 1, and the thirteenth cell set is cell 2.

[0693] For example, a terminal device includes / has two DRX groups, a first DRX group corresponding to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponding to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If, at a first time, the on-duration timer of the first DRX group is not running, but the on-duration timer of the multicast DRX corresponding to multicast 1 is running, for cells other than both cell 1 and cell 2 in the first cell set (i.e., cell 3), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, the third timer set is the on-duration timer of the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, the fifth cell set is cell 3, the seventh cell set is cell 1, and the thirteenth cell set is cell 2.

[0694] For example, a terminal device includes / has two DRX groups, where a first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and a second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, the terminal device receives multicast 2 in cell 2, and the terminal device receives multicast 4 in cell 4. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If, at a first time, the on-duration timer of the first DRX group is not running but the on-duration timer of the multicast DRX corresponding to multicast 1 is running, then for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 3), the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, the third timer set is a multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2 and cell 3, the fifth cell set is cell 2 and cell 3, the seventh cell set is cell 1, and the thirteenth cell set is cell 1.

[0695] For example, for a cell set or cell other than the fifth cell set (e.g., the seventh cell set and / or the thirteenth cell set), the terminal device may transmit the first CSI or CSI at the first time. For example, in a cell or cell set associated with the seventh multicast service set, the terminal device may transmit the first CSI at the first time. Alternatively, in a cell or cell set associated with the eleventh multicast service set, the terminal device may transmit the first CSI at the first time.

[0696] In this embodiment of the present application, when a multicast DRC is not set in a multicast in which a terminal device participates, the terminal device may report CSI, so that the base station can obtain CSI, which helps the base station perform multicast scheduling.

[0697] Optionally, the preset conditions include condition 4, and the preset conditions may further include condition 5.

[0698] Optionally, the pre-set conditions may include condition 4, and the method 400 of the present application may further include condition 5 being satisfied.

[0699] For example, if condition 4 and condition 5 are satisfied, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0700] For example, if condition 4 and condition 5 are satisfied, for the fifth cell set, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0701] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of the on-duration timer corresponding to unicast, or the on-duration timer corresponding to unicast is started or restarted, and at symbol n, the on-duration timer corresponding to unicast is not activated but the on-duration timer corresponding to multicast is activated, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than one or both of the cells associated with multicast (e.g., the cells associated with multicast for which symbol n is within the active time of multicast DRX) and / or the cells associated with multicast for which multicast DRX is not configured.

[0702] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of the on-duration timer corresponding to unicast or the on-duration timer corresponding to unicast is started or restarted and, for symbol n, the on-duration timer corresponding to the DRX group is not running but the on-duration timer corresponding to the multicast associated with the DRX group is running, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than one or both of the cells associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of multicast DRX) and / or the cells associated with the multicast for which multicast DRX is not configured within the DRX group, or in cells or cell sets other than one or both of the cells associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of multicast DRX) and / or the cells associated with the multicast for which multicast DRX is not configured within the DRX group.

[0703] Optionally, the preset conditions include condition 4, and the preset conditions may further include condition 8.

[0704] Optionally, the pre-set conditions may include condition 4, and the method 400 of the present application may further include condition 8 being satisfied.

[0705] For example, if condition 4 and condition 8 are satisfied, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0706] For example, if condition 4 and condition 8 are satisfied, for the fifth cell set, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0707] For example, if CSI masking is configured for a terminal device and, at symbol n, the on-duration timer corresponding to unicast is not running but the on-duration timer corresponding to multicast is running, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than both / one of the cells associated with multicast (e.g., the cells associated with multicast for which symbol n is within the active time of multicast DRX) and / or the cells associated with multicast for which multicast DRX is not configured.

[0708] For example, if CSI masking is configured for a terminal device and, at symbol n, the on-duration timer corresponding to unicast is not running but the on-duration timer corresponding to multicast is running, the terminal device skips transmitting CSI on the PUCCH for a cell or cell set other than the cell associated with multicast (e.g., the cell associated with multicast for which symbol n is within the active time of multicast DRX) and / or the cell associated with multicast for which multicast DRX is not configured in the DRX group, or in a cell or cell set other than the cell associated with multicast (e.g., the cell associated with multicast for which symbol n is within the active time of multicast DRX) and / or the cell associated with multicast for which multicast DRX is not configured in the DRX group.

[0709] For example, if condition 4, condition 5, and condition 8 are satisfied, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0710] For example, if condition 4, condition 5, and condition 8 are satisfied, for the fifth cell set, the terminal device skips transmitting the first CSI or the seventh CSI at the first time.

[0711] For example, if DCP is not configured for a terminal device and symbol n is not within the duration of the on-duration timer corresponding to unicast, or the on-duration timer corresponding to unicast is started or restarted, and CSI masking is configured for the terminal device and, for symbol n, the on-duration timer corresponding to unicast is not running but the on-duration timer corresponding to multicast is running, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than both / one of the cells associated with multicast (e.g., cells associated with multicast for which symbol n is within the active time of multicast DRX) and / or cells associated with multicast for which multicast DRX is not configured.

[0712] For example, if DCP is not configured for the terminal device and symbol n is not within the duration of the on-duration timer corresponding to unicast, or the on-duration timer corresponding to unicast is started or restarted and CSI masking is configured for the terminal device and, for symbol n, the on-duration timer corresponding to the DRX group is not running but the on-duration timer corresponding to the multicast associated with the DRX group is running, the terminal device skips transmitting CSI on the PUCCH for cells or cell sets other than the cell associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of multicast DRX) and / or the cell associated with the multicast for which multicast DRX is not configured in the DRX group, or in cells or cell sets other than the cell associated with the multicast (e.g. the cell associated with the multicast for which symbol n is within the active time of multicast DRX) and / or the cell associated with the multicast for which multicast DRX is not configured in the DRX group.

[0713] Condition 10: The first timer is not running at the first time, and the first time does not belong to the active time of the fourth DRX set.

[0714] The fourth DRX set includes at least one multicast DRX, and the at least one DRX includes a fourth multicast DRX, where the fourth multicast DRX is for controlling monitoring of the control information related to the fifth multicast service.

[0715] For example, the fourth DRX set may include a DRX corresponding to a multicast / multicast service received by the terminal device, or a DRX corresponding to a multicast / multicast service in which the terminal device joins.

[0716] For example, the fourth DRX set may include a DRX corresponding to any multicast / multicast service / all multicast / multicast services received by the terminal device, or a DRX corresponding to any multicast / multicast service / all multicast / multicast services in which the terminal device participates.

[0717] For example, the fourth DRX set may be associated with a sixth multicast service set, and the sixth multicast service set may include a fifth multicast service.

[0718] The sixth multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0719] For example, the sixth multicast service set may include any multicast / multicast services / all multicast / multicast services received by the terminal device, or any multicast / multicast services / all multicast / multicast services in which the terminal device participates.

[0720] For example, the fifth multicast service may be understood as a multicast service associated with the 5G-RNTI and / or the 5G-CS-RNTI, or a multicast associated with the 5G-RNTI and / or the 5G-CS-RNTI.

[0721] The fourth multicast DRX may alternatively be for controlling the terminal device to monitor other control information, which should be noted that this is not limited in this application.

[0722] For example, control information relating to the fifth multicast service may include / be understood as control information associated with (or scrambled by using) the 5G-RNTI and / or the 5G-CS-RNTI, and / or control information scrambled by using a unicast RNTI (e.g., a C-RNTI and / or a CS-RNTI).

[0723] For example, the active time of the fourth multicast DRX may include any one or more of the following: an operation time of an on-duration timer (e.g., drx-onDurationTimerPTM) corresponding to the fifth multicast service (or the 5th multicast service and / or the 5th G-RNTI and / or the 5th CS-RNTI); an operation time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to the fifth multicast service (or the 5th G-RNTI and / or the 5th CS-RNTI); or an operation time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to the fifth multicast service (or the 5th G-RNTI and / or the 5th CS-RNTI).

[0724] For example, the active time of the fourth DRX set may include any one or more of the following: the active time of the DRX set corresponding to the sixth multicast service set, the active time of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the sixth multicast service set, or the active time of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the sixth DRX set.

[0725] For example, the active time of the 4th DRX set may include any one or more of the following: the operation times of drx-onDurationTimerPTM, drx-InactivityTimerPTM, or drx-RetransmissionTimerDL-PTM that are specific to the G-RNTI set and / or G-CS-RNTI set corresponding to the 4th DRX set.

[0726] Optionally, the preset condition includes condition 10, and skipping the terminal device from transmitting the first CSI at the first time includes, for the first cell set, skipping the terminal device from transmitting the first CSI at the first time.

[0727] It should be understood that for the description of "for the first cell set, the terminal device skips transmitting the first CSI at the first time", reference should be made to the above related description. For the sake of brevity, the details will not be described again.

[0728] Optionally, the first set of cells includes an eighth set of cells.

[0729] For example, the eighth cell set is a subset of the first cell set, or the eighth cell set is equal to the first cell set.

[0730] The eighth cell set is associated with the fourth DRX set, the eighth cell set including at least one cell.

[0731] It can be understood that the fourth DRX set may be associated with the first DRX.

[0732] For example, the fourth DRX set may include a DRX received by the terminal device and corresponding to a multicast / multicast service associated with the first cell set / first DRX, a DRX corresponding to a multicast / multicast service in which the terminal device participates and associated with the first cell set / first DRX, or a DRX corresponding to a multicast / multicast service associated with the first cell set / first DRX.

[0733] For example, the fourth DRX set may include a DRX corresponding to any / all multicast / multicast services received by the terminal device and associated with the first cell set / first DRX, a DRX corresponding to any / all multicast / multicast services in which the terminal device participates and associated with the first cell set / first DRX, or a DRX corresponding to any / all multicast / multicast services associated with the first cell set / first DRX.

[0734] In some examples, the fourth DRX set may include / be a multicast DRX set associated with the first DRX set or a multicast DRX set corresponding to a multicast service associated with the first cell set.

[0735] For example, a terminal device includes / has two DRX groups, a first DRX group corresponding to three cells, namely cell 1, cell 2, and cell 3, and a second DRX group corresponding to three cells, namely cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1. If the timer of the first DRX group is not running at the first time and the first time is not within the active time of the multicast DRX corresponding to multicast 1, for the first DRX group / first cell set, the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fourth DRX set is the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, and the eighth cell set is cell 1.

[0736] For example, a terminal device includes / has two DRXs, a first DRX group corresponding to three cells, namely cell 1, cell 2, and cell 3, and a second DRX group corresponding to three cells, namely cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. If the timer of the first DRX group is not running at the first time, and the first time is not within the active time of the multicast DRX corresponding to multicast 1 or the active time of the multicast DRX corresponding to multicast 2, for the first DRX group / first cell set, the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fourth DRX set is the multicast DRX corresponding to multicast 1 and the multicast DRX corresponding to multicast 2, the first cell set is cell 1, cell 2, and cell 3, and the eighth cell set is cell 1 and cell 2.

[0737] It should be understood that for other descriptions of the fourth DRX set, reference should be made to the above related descriptions of the second DRX set. For the sake of brevity, details will not be described again.

[0738] In some embodiments, it may be determined by the terminal device that the first time does not belong to the active time of the fourth DRX set.

[0739] Optionally, the first time not belonging to the active time of the fourth DRX set includes: the terminal device determining that the first time not belongs to the active time of the fourth DRX set.

[0740] It should be understood that for a specific explanation of the terminal device determining that the first time does not belong to the active time of the fourth DRX set, reference should be made to the relevant description of the terminal device determining that the first time does not belong to the active time of the second DRX set.

[0741] In other embodiments, determining that the first time does not belong to the active time of the first timer and that the first time does not belong to the active time of the fourth DRX set includes the terminal device determining that the first time does not belong to the active time of the first timer and that the first time does not belong to the active time of the fourth DRX set.

[0742] It should be understood that for the technical solution, the terminal device should refer to the above related description of determining that the first time does not belong to the active time of the first timer and that the first time does not belong to the active time of the fourth DRX set. For the sake of brevity, the details will not be described again.

[0743] Optionally, the preset conditions include condition 10 and the 1st CSI may be replaced with / which may include / which may be the 8th CSI.

[0744] For the 8th CSI, please refer to the relevant description of the 2nd CSI.

[0745] Optionally, the pre-set conditions may include condition 10, and "the terminal device skips transmitting the first CSI at the first time" may be replaced with "the terminal device skips transmitting the eighth CSI at the first time."

[0746] It should be understood that for a description of the content included in a terminal device skipping transmitting the 8th CSI at the first time, reference should be made to the above related description of the content included in a terminal device skipping transmitting the 2nd CSI at the first time.

[0747] Optionally, the preset conditions include condition ten, and the preset conditions may further include condition five.

[0748] Optionally, the pre-set conditions may include condition 10, and the method 400 of the present application may further include condition 5 being satisfied.

[0749] For example, if condition 10 and condition 5 are satisfied, the terminal device skips transmitting the first CSI or the eighth CSI at the first time.

[0750] For example, if condition 10 and condition 5 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI or the eighth CSI at the first time.

[0751] Optionally, the preset conditions include condition 10, and the preset conditions may further include condition 6.

[0752] Optionally, the preset conditions include condition 10, and the method may further include condition 6 being satisfied.

[0753] For example, if condition 10 and condition 6 are satisfied, the terminal device skips transmitting the first CSI at the first time.

[0754] For example, if condition 10 and condition 6 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI at the first time.

[0755] Optionally, the preset conditions include condition 10, and the preset conditions may further include condition 7.

[0756] Optionally, the preset conditions include condition 10, and the method may further include condition 7 being satisfied.

[0757] For example, if condition 10 and condition 7 are satisfied, the terminal device skips transmitting the first CSI at the first time.

[0758] For example, if condition 10 and condition 7 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI at the first time.

[0759] For example, if condition 10, condition 6, and condition 7 are satisfied, the terminal device skips transmitting the first CSI at the first time.

[0760] For example, if condition 10, condition 6, and condition 7 are satisfied, for the first cell set, the terminal device skips transmitting the first CSI at the first time.

[0761] Condition 11: The first timer is not running at the first time, and the first time belongs to the active time of the fifth DRX set.

[0762] The fifth DRX set includes at least one multicast DRX, and the at least one multicast DRX includes a fifth multicast DRX, where the fifth multicast DRX is for controlling monitoring of the control information related to the sixth multicast service.

[0763] For example, the fifth DRX set may include a DRX corresponding to a multicast / multicast service received by the terminal device, or a DRX corresponding to a multicast / multicast service in which the terminal device joins.

[0764] For example, the fifth DRX set may include a DRX corresponding to any multicast / multicast service / all multicast / multicast services received by the terminal device, or a DRX corresponding to any multicast / multicast service / all multicast / multicast services in which the terminal device participates.

[0765] For example, the fifth DRX set may be associated with a seventh multicast service set, and the seventh multicast service set may include a sixth multicast service.

[0766] For example, the seventh multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0767] For example, the sixth multicast service may be understood as a multicast service associated with the 6G-RNTI and / or the 6G-CS-RNTI, or a multicast associated with the 6G-RNTI and / or the 6G-CS-RNTI.

[0768] For example, control information relating to the sixth multicast service may include / be understood as control information associated with (or scrambled by using) the 6G-RNTI and / or the 6G-CS-RNTI, and / or control information scrambled by using a unicast RNTI (e.g., a C-RNTI and / or a CS-RNTI).

[0769] It should be noted that the fifth multicast DRX may alternatively be for controlling the monitoring of other control information, which is not limited in this application.

[0770] For example, the active time of the 5th multicast DRX may include any one or more of the following: an operation time of an on-duration timer (e.g., drx-onDurationTimerPTM) corresponding to the 6th multicast service (or the 6th G-RNTI and / or the 5th G-CS-RNTI); an operation time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to the 6th multicast service (or the 6th G-RNTI and / or the 6th G-CS-RNTI); or an operation time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to the 2nd multicast service (or the 6th G-RNTI and / or the 6th G-CS-RNTI).

[0771] For example, the active time of the 5th DRX set may include any one or more of the following: the active time of the DRX set corresponding to the 6th multicast service set, the active time of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the 6th multicast service set, or the active time of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the 7th DRX set.

[0772] For example, the active time of the 5th DRX set may include any one or more of the following: operation times of drx-onDurationTimerPTM, drx-InactivityTimerPTM, or drx-RetransmissionTimerDL-PTM that are specific to the G-RNTI set and / or G-CS-RNTI set corresponding to the 5th DRX set.

[0773] It should be noted that the active time of the fifth DRX set may further include other times, which is not limited in this application.

[0774] Optionally, the preset condition may include condition 11, and skipping the terminal device from transmitting the first CSI at the first time may include skipping the terminal device from transmitting the first CSI at the first time for a ninth cell set.

[0775] The ninth cell set includes at least one cell, and the ninth cell set is not associated with the fifth DRX set.

[0776] For example, the 14th cell set is associated with the 5th DRX set or the 7th multicast service set.

[0777] The fourteenth set of cells includes at least one cell

[0778] The ninth cell set not being associated with the fifth DRX set may be understood as the ninth cell set not being associated with the seventh multicast service set.

[0779] For example, the ninth cell set may be understood as / include a cell / cell set other than the cell / cell set associated with the seventh multicast service set, or a cell / cell set other than the fourteenth cell set.

[0780] Optionally, the ninth cell set is associated with the first DRX.

[0781] For example, the association of a 9th cell set with the 1st DRX may be understood as the cells included in the 9th cell set using the same DRX parameters (e.g., parameters relating to the 1st DRX) and the reception of control information of the cells included in the 9th cell set being controlled by the same DRX (e.g., the 1st DRX).

[0782] Optionally, the fourteenth cell set is associated with the first DRX.

[0783] For example, the association of a 14th cell set with the first DRX may be understood as the cells included in the 14th cell set using the same DRX parameters (e.g., parameters relating to the first DRX) and the reception of control information for the cells included in the 14th cell set being controlled by the same DRX (e.g., the first DRX).

[0784] Optionally, the first set of cells includes a ninth set of cells.

[0785] For example, the ninth cell set is a subset of the first cell set, or the ninth cell set is equal to the first cell set.

[0786] In some embodiments, the terminal device includes / has two DRX groups, where the first DRX group corresponds to three cells, namely cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, namely cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1. If the timer of the first DRX group is not running at the first time but the first time is within the active time of the multicast DRX corresponding to multicast 1, for cells other than cell 1 in the first cell set (i.e. cell 2 and cell 3), the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fifth DRX set is the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, and the ninth cell set is cell 2 and cell 3.

[0787] In some embodiments, the terminal device includes / has two DRX groups, where the first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. If the timer of the first DRX group is not running at the first time, but the first time is within the active time of the multicast DRX corresponding to multicast 1 and the active time of the multicast DRX corresponding to multicast 2, for cells other than both cell 1 and cell 2 in the first cell set (i.e., cell 3), the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fifth DRX set is the multicast DRX corresponding to multicast 1 and the multicast DRX corresponding to multicast 2, the first cell set is cell 1, cell 2, and cell 3, and the ninth cell set is cell 3.

[0788] Optionally, the ninth cell set is not associated with the eighth multicast service set.

[0789] The eleventh multicast service set includes at least one multicast service, and the at least one multicast service includes a twelfth multicast service.

[0790] Multicast DRX is not configured for the twelfth multicast service.

[0791] It should be understood that for the twelfth multicast service, reference should be made to the above related description of the second multicast service.

[0792] For example, the 15th cell set is associated with the 8th multicast service set.

[0793] The fifteenth cell set includes at least one cell.

[0794] For example, the ninth cell set not being associated with the eighth multicast service set may be understood as the ninth cell set not being associated with the fifteenth cell set.

[0795] For example, the ninth cell set may be understood as / include a cell / cell set other than the cell / cell set associated with the eighth multicast service set, or a cell / cell set other than the fifteenth cell set.

[0796] It should be noted that condition 11 may be replaced by the first timer not running at the first time. That is, it is not essential that the first time belongs to the active time of the 5th DRX set. For example, in the case where there is an 8th multicast service set / 15th cell set, condition 11 may be that the first timer is not running at the first time. In this way, the UE can report CSI for / in the multicast-enabled cells for which DRX is not configured.

[0797] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the timer of the first DRX group is not running at the first time, and the first time is not within the active time of multicast DRX corresponding to multicast 1, for cells 3 and 1, the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fifth DRX set is the multicast DRX corresponding to multicast 1, the ninth cell set is cell 3 and cell 1, and the fifteenth cell set is cell 2.

[0798] For example, a terminal device includes / has three cells, namely cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the timer of the first DRX group is not running at the first time, and the first time is within the active time of multicast DRX corresponding to multicast 1, for cell 3, the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fifth DRX set is the multicast DRX corresponding to multicast 1, the ninth cell set is cell 3, the fourteenth cell set is cell 1, and the fifteenth cell set is cell 2.

[0799] For example, if the on-duration timer corresponding to the unicast is not running at symbol n, for a cell or cell set other than the cell associated with the multicast for which multicast DRX is not set, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0800] For example, if the on-duration timer corresponding to a unicast is not running at symbol n but symbol n is within the active time of a multicast DRX in which the terminal device participates, for cells or cell sets other than both the cell associated with the multicast (e.g., the cell associated with the multicast in which symbol n is within the active time of the multicast DRX) and the cell associated with the multicast in which multicast DRX is not set, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0801] Optionally, the eighth multicast service set / the fifteenth cell set is associated with the first DRX / the first cell set.

[0802] For example, the eighth multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX and in which multicast DRX is not set, a multicast / multicast service in which the terminal device participates and associated with the first cell set / first DRX and in which multicast DRX is not set, or a multicast / multicast service associated with the first cell set / first DRX and in which multicast DRX is not set.

[0803] For example, the eighth multicast service set may include any one or more / all multicast / multicast services received by the terminal device and associated with the first cell set / first DRX and for which multicast DRX is not configured, any one or more / all multicast / multicast services joined by the terminal device and associated with the first cell set / first DRX and for which multicast DRX is not configured, or any one or more / all multicast / multicast services associated with the first cell set / first DRX and for which multicast DRX is not configured.

[0804] For example, the association of the 8th multicast service set / 15th cell set with the 1st DRX / 1st cell set may be understood as the cells included in the 15th cell set using the same DRX parameters (e.g., parameters relating to the 1st DRX) and the reception of control information of the cells included in the 15th cell set being controlled by the same DRX (e.g., the 1st DRX).

[0805] Optionally, the first set of cells comprises a fifteenth set of cells.

[0806] For example, the fifteenth cell set is a subset of the first cell set, or the fifteenth cell set is equal to the first cell set.

[0807] Optionally, the first set of cells includes a ninth set of cells and a fifteenth set of cells.

[0808] For example, the ninth cell set and the fifteenth cell set are equal to the first cell set.

[0809] For example, the ninth cell set and the fifteenth cell set do not have an intersection set.

[0810] For example, if the on-duration timer corresponding to the DRX group is not running at symbol n, for a cell or set of cells other than the cell associated with the multicast for which multicast DRX is not configured in the DRX group, the terminal device skips transmitting semi-persistent CSI configured on the PUSCH and / or the terminal device skips transmitting CSI on the PUCCH.

[0811] Optionally, the first set of cells includes a ninth cell set, a fourteenth cell set, and a fifteenth cell set. Alternatively, optionally, the first set of cells includes a ninth cell set and a union of the fourteenth cell set and the fifteenth cell set.

[0812] For example, the ninth cell set, the fourteenth cell set, and the fifteenth cell set are equal to the first cell set.

[0813] For example, the ninth cell set and the fifteenth cell set do not have an intersection set.

[0814] For example, the ninth cell set and the union of the fourteenth cell set and the fifteenth cell set have no intersection set.

[0815] It should be noted that the fourteenth cell set and the fifteenth cell set may or may not have an intersection set, and this is not a limitation in the present application.

[0816] It should be noted that the 14th cell set and the 15th cell set may be the same or different, and this is not a limitation in the present application.

[0817] For example, the terminal device includes / has two DRX groups, the first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the timer of the first DRX group is not running at the first time and is not within the active time of the multicast DRX corresponding to multicast 1 at the first time, for cells other than cell 2 in the first cell set (i.e., cell 3 and cell 1), the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fifth DRX set is the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, the ninth cell set is cell 3 and cell 1, and the fifteenth cell set is cell 2.

[0818] For example, the terminal device includes / has two DRX groups, the first DRX group corresponds to three cells, i.e., cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, i.e., cell 4, cell 5, and cell 6. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. Multicast DRX is configured for multicast 1, and multicast DRX is not configured for multicast 2. If the timer of the first DRX group is not running at the first time and the first time is within the active time of multicast DRX corresponding to multicast 1, for cells other than both cell 1 and cell 2 in the first cell set (i.e., cell 3), the terminal device skips transmitting the first CSI at the first time. The first timer is the timer of the first DRX group, the fifth DRX set is the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, the ninth cell set is cell 3, the fourteenth cell set is cell 1, and the fifteenth cell set is cell 2.

[0819] It should be understood that for cell sets or cells other than the 9th cell set (e.g., the 14th cell set and / or the 15th cell), the terminal device may transmit the first CSI or CSI at the first time. For example, in a cell or cell set associated with the 8th multicast service set, the terminal device may transmit the first CSI at the first time. Alternatively, in a cell or cell set associated with the 12th multicast service set, the terminal device may transmit the first CSI at the first time.

[0820] In this embodiment of the present application, when a multicast DRC is not set in a multicast in which a terminal device participates, the terminal device may report CSI, so that the base station can obtain CSI, which helps the base station perform multicast scheduling.

[0822] Optionally, the first time not belonging to the active time of the fifth DRX set includes: the terminal device determining that the first time not belongs to the active time of the fifth DRX set.

[0824] In another embodiment, determining that the first time does not belong to the active time of the first timer and that the first time belongs to the active time of the fifth DRX set includes the terminal device determining that the first time does not belong to the active time of the first timer and that the first time belongs to the active time of the fifth DRX set.

[0825] It should be understood that for the technical solution, reference should be made to the above relevant description that the terminal device determines that the first time does not belong to the active time of the first DRX set, and that the first time belongs to the active time of the third DRX set.

[0838] Optionally, the preset conditions include condition 11, and the preset conditions may further include condition 7.

[0839] Optionally, the preset conditions include condition 11, and the method may further include that condition 7 is satisfied.

[0840] For example, if condition 11 and condition 7 are satisfied, the terminal device skips transmitting the first CSI at the first time.

[0841] For example, if condition 11 and condition 7 are satisfied, for the ninth cell set, the terminal device skips transmitting the first CSI at the first time.

[0842] For example, if condition 11, condition 6, and condition 7 are satisfied, the terminal device skips transmitting the first CSI at the first time.

[0845] The fourth set of timers includes at least one multicast timer, and the at least one multicast timer includes a fifth multicast timer, and during operation of the fifth multicast timer, the terminal device may monitor control information related to the seventh multicast service.

[0846] For example, the fourth set of timers may include a multicast timer corresponding to a multicast / multicast service received by the terminal device or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins.

[0847] For example, the fourth timer set may include multicast timers corresponding to any multicast / multicast service / all multicast / multicast services received by the terminal device, or any multicast / multicast service / all multicast / multicast services in which the terminal device participates.

[0848] A fourth timer set not running at a first time may be understood as none of the timers in the fourth timer set running at the first time.

[0849] For example, the fourth timer set may be associated with an eleventh multicast service set, where the eleventh multicast service set includes a seventh multicast service.

[0850] For example, the fourth set of timers may include a multicast timer corresponding to a multicast / multicast service received by the terminal device or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins.

[0851] For example, the fourth timer set may include multicast timers corresponding to any multicast / multicast service / all multicast / multicast services received by the terminal device, or any multicast / multicast service / all multicast / multicast services in which the terminal device participates.

[0852] For example, the eleventh multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0853] For example, the eleventh multicast service set may include any multicast / multicast services / all multicast / multicast services received by the terminal device, or any multicast / multicast services / all multicast / multicast services in which the terminal device participates.

[0855] For example, control information relating to the seventh multicast service may include / be understood as control information associated with (or scrambled by using) the 14G-RNTI and / or the 14G-CS-RNTI, and / or control information scrambled by using a unicast RNTI (e.g., a C-RNTI and / or a CS-RNTI).

[0856] It should be noted that during the operation of the fifth multicast timer, the terminal device may alternatively monitor other control information, which is not limited in this application.

[0857] The fifth multicast timer may be a timer for the seventh multicast service, a drx-onDurationTimerPTM for the seventh multicast service, a timer for the 14G-RNTI and / or the 14G-CS-RNTI, or a drx-onDurationTimerPTM for the 14G-RNTI and / or the 14G-CS-RNTI.

The terminal device receives multicast 1 in cell 1. If the first time is not within the active time of the first DRX group and the timer of the multicast DRX corresponding to multicast 1 is not running, for the first DRX group / first cell set, the terminal device skips transmitting the first CSI at the first time. The first DRX is the first DRX group, the fourth timer set is the timer of the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, and the tenth cell set is cell 1.
