Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202210957937.2, entitled "COMMUNICATION METHOD AND COMMUNICATION APPARATUS," filed with the State Intellectual Property Office of China on August 10, 2022, which is incorporated herein by reference in its entirety.

[0002] TECHNICAL FIELD Embodiments of the present application relate to the field of communications, and more particularly to a communication method and a communication device. [Background technology]

[0003] In wireless communication systems, discontinuous reception (DRX) is introduced to reduce the power consumption of terminal devices while ensuring effective data transmission. When a network device configures a DRX function for a terminal device, the terminal device may enter a dormant state at a certain moment, so the terminal device does not need to continuously monitor a physical downlink control channel (PDCCH). When the PDCCH needs to be monitored, the terminal device can be woken up from the dormant state. This can reduce the power consumption of the terminal device to a certain extent.

[0004] Bandwidth part (BWP) is supported in new radio (NR). After multicast is introduced in NR, the configuration message of BWP may include information about multicast common frequency resource (CFR).

[0005] In the prior art, if multicast DRX is within a valid time or if multicast DRX is not configured for multicast, the terminal device may report CSI that is not required. Summary of the Invention [Means for solving the problem]

The following provides an explanation by using an example in which the access network device is a base station. Multiple network devices in a communication system may be the same type of base station or different types of base stations. A base station may communicate with a terminal device, or may communicate with the terminal device via a relay station. A terminal device may communicate with multiple base stations with different access technologies. The core network device is configured to implement functions such as mobility management, data processing, session management, and policy and charging.The names of devices implementing core network functions in systems of different access technologies may be different, which is not limited in this application.

[0103] To better understand the communication method disclosed in the embodiments of the present application, relevant concepts in the embodiments of the present application will be briefly described.

[0104] 1. Multicast and broadcast services (MBS) The multicast or multicast service referred to in the embodiments of this application may be MBS in a new radio (NR) system. MBS was introduced by 3GPP to efficiently use mobile communication network resources and provides a point-to-multipoint service in which a data source transmits data to multiple users in a mobile communication network, thereby implementing network resource sharing and improving resource utilization, especially air interface resources. NR MBS supports multicast and broadcast.

[0105] 2. Multicast and Unicast Multicast may include any one or more of broadcast in a multimedia broadcast multicast service (MBMS) or MBS, groupcast in MBMS or MBS, multicast in MBMS or MBS, groupcast in V2X, multicast in V2X, broadcast in V2X, multicast or groupcast, groupcast, and broadcast.

[0106] The groupcast service may include / be replaced with any one or more of a broadcast service, a multicast service, an MBS service, an MBS broadcast service, an MBS multicast service, a V2X multicast service, and a V2X broadcast service.

[0107] Data corresponding to a multicast service may be referred to as multicast data.

[0108] The unicast may include one or both of a unicast and a unicast in V2X. Optionally, the unicast may be understood as a unicast transmission.

[0109] A multicast service may also be understood as a multicast session or an MBS session.

[0110] The term "groupcast" in the embodiments of the present application may also be replaced with a noun such as "multicast." Correspondingly, the term "groupcast service" may also be replaced with a multicast service.

[0111] Multicasting may provide the same service and / or the same content data to a group / multiple terminal devices at the same time.

[0112] For example, the multicast may be to a specific group of terminal devices, which may require the terminal devices to perform a "group joining process."

[0113] Correspondingly, unicasting can be understood as providing the same service and / or the same content data to one terminal device at the same time. Unicasting can be understood as follows: if one piece of data needs to be transmitted to multiple devices, the data needs to be transmitted to each device separately.

[0114] 3. Discontinuous reception (DRX) In a wireless communication system, in order to further reduce the power consumption of a terminal device while ensuring that data can be transmitted effectively, a DRX function is introduced to control the behavior of monitoring the PDCCH by the terminal device. When a network device configures the DRX function for a terminal device, the terminal device may enter a dormant state at a certain moment, so the terminal device does not need to continuously monitor the PDCCH. When the PDCCH needs to be monitored, the terminal device can be woken up from the dormant state. This can reduce the power consumption of the terminal device to a certain extent.

[0115] Below, DRX will be briefly explained with reference to FIG.

[0116] FIG. 2 is a diagram of a DRX cycle according to an embodiment of the present application. As shown in FIG. 2, a DRX cycle may include a duration (e.g., on-duration) or awake time (e.g., on-duration) and a sleep time (e.g., opportunity for DRX). The duration period is the length of time that the terminal device waits to receive the PDCCH after waking up. During this duration period, the terminal device monitors the PDCCH. If the terminal device can successfully decode the PDCCH, the terminal device may stay awake or extend the validity time. The sleep time period is the sleep time of the terminal device. During this period, the terminal device does not need to monitor the PDCCH to reduce power consumption. It can be understood that a longer sleep time of the terminal device indicates lower power consumption of the terminal device, but a corresponding increase in the delay of service transmission of the terminal device.

[0117] The DRX function of the terminal device may be configured by the network device. Note that even if the network device configures the DRX function for the terminal device, the terminal device may monitor the PDCCH based on the requirements of another medium access control (MAC) layer process. Specifically, when another MAC layer process requests the terminal device to continue monitoring the PDCCH, the terminal device in this case needs to continuously monitor the PDCCH regardless of the DRX state.

[0118] 3.1 Unicast DRX When a DRX group is not configured (or in R15), DRX parameters are configured by the network device for the MAC entity of each terminal device, or each terminal device, i.e., the MAC entity of one terminal device, uses one set of DRX parameters.

[0119] In a carrier aggregation (CA) scenario, the terminal device uses the same set of DRX parameters for all active cells and performs one set of DRX.

[0120] In a multi-radio dual connectivity (MR-DC) scenario, a master node (MN) and a secondary node (SN) each correspond to a MAC entity of one terminal device. Therefore, the terminal device has two independent sets of DRX parameters for the MN and the SN and performs two sets of DRX. Specifically, the terminal device performs one set of DRX for all active serving cells in a master cell group (MCG) using one set of DRX parameters, and performs another set of DRX for all active serving cells in a secondary cell group (SCG) using another set of DRX parameters.

[0121] When no DRX group is configured, the DRX valid time is drx-onDuration Timer operation time, drx-InactivityTimer operation time, drx-RetransmissionTimerDL operation time, drx-RetransmissionTimerUL operation time, drx-RetransmissionTimerSL operation time, The time a scheduling request (SR) is sent on the physical uplink control channel (PUCCH) and the SR is waiting to be processed, and The time during which a PDCCH scrambled by the C-RNTI and indicating that no new transmissions have been received after the random access response (RA) is successfully received in a non-contention-based random access process (i.e., after a successful non-contention-based random access (RA)). may include any one or more of:

[0122] A network device controls DRX operation by configuring any one or more of the following parameters by using Radio Resource Control (RRC) messages: drx-onDurationTimer: The period at the beginning of the DRX cycle. The point at which the drx-onDurationTimer is started or restarted may be calculated based on parameters configured by the base station and formulas specified in the protocol. drx-InactivityTimer: A period of time after a PDCCH occasion when a new uplink or downlink transmission is indicated. For example, a terminal device receives a PDCCH (e.g., a PDCCH scrambled by a C-RNTI or a CS-RNTI) indicating that there is a new uplink or downlink transmission (i.e., a new transmission scheduled), and the drx-InactivityTimer is started or restarted. drx-RetransmissionTimerDL: The maximum length of time before a downlink (DL) retransmission is received. For example, if drx-HARQ-RTT-TimerUL expires and the data is not successfully decoded, drx-RetransmissionTimerDL is started or restarted. drx-RetransmissionTimerUL: The maximum length of time until a grant for uplink (UL) retransmission is received, e.g., at the first symbol after drx-HARQ-RTT-TimerUL expires, drx-RetransmissionTimerUL is started or restarted for the corresponding HARQ process. Drx-HARQ-RTT-TimerDL: The minimum length of time until a DL allocation for HARQ retransmission is expected by the MAC entity, or until a DL allocation for HARQ retransmission is expected to be received by the MAC entity. For example, a terminal device receives a PDCCH (e.g., a PDCCH scrambled by C-RNTI or CS-RNTI) indicating a downlink transmission, or the terminal device receives data in a configured downlink allocation (e.g., SPS resources related to unicast), and drx-HARQ-RTT-TimerDL is started or restarted after the feedback, where RTT stands for Round Trip Time. drx-HARQ-RTT-TimerUL: The minimum length of time until a UL HARQ retransmission grant is expected by the MAC entity or until a UL HARQ retransmission grant is expected to be received by the MAC entity. For example, the terminal device transmits a MAC protocol data unit (PDU) in a configured uplink grant (e.g., SPS resources related to unicast), or the terminal device receives a PDCCH indicating a UL transmission, and drx-HARQ-RTT-TimerUL is started or restarted. drx-RetransmissionTimerSL: The maximum time until a grant for sidelink (SL) retransmission is received, and drx-HARQ-RTT-TimerSL: The minimum length of time until an SL retransmission grant is expected or until an SL retransmission grant is expected to be received.

[0123] Compared to R15, the R16 standard protocol adds the features of DRX group and DCI with CRC scrambled by power saving radio network temporary identifier (PS-RNTI, DCP) to unicast DRX.

[0124] Below is a brief description of the DRX group.

[0125] DRX group: In one MAC entity, different DRX groups are distinguished based on different frequency ranges. For example, DRX groups are distinguished based on frequency range (FR)1 and FR2. In other words, the concept of a secondary DRX group is introduced for cells in FR2. Each cell belongs to one DRX group.

[0126] For each cell group / DRX group in FR1 and FR2 there is a set of drx-onDurationTimer and drx-InactivityTimer parameters, and other DRX parameters are shared.

[0127] Each DRX group performs one set of DRX, ie, in one MAC entity, there may be two DRX groups and two sets of DRX are performed.

[0128] When a DRX group is configured, the validity period of the DRX group is The operation time of the drx-onDurationTimer in the DRX group, The operation time of the drx-InactivityTimer for the DRX group, The activation time of the drx-RetransmissionTimerDL corresponding to the DRX group (or of any cell in the DRX group), The validity period of the drx-RetransmissionTimerUL corresponding to the DRX group (or the activation period of any cell in the DRX group), The activation time of the drx-RetransmissionTimerSL corresponding to the DRX group (or of any cell in the DRX group), The time when an SR is sent on the PUCCH and the SR is waiting to be processed, and The time during which a PDCCH scrambled by the C-RNTI and indicating that no new transmissions are received after an RAR is successfully received in a non-contention-based random access process (i.e., after a successful non-contention-based RA). may include any one or more of:

[0129] Below is a brief description of DCP.

[0130] DCP: When the network device configures the DCP function for the terminal device, the terminal device monitors the DCI with CRC scrambled by the PS-RNTI at a time before the drx-onDurationTimer is started to determine whether to start the drx-onDurationTimer, thereby further reducing the power consumption of the terminal device.

[0131] For example, when the DCP function is configured for a terminal device, the terminal device may determine whether to start the drx-onDurationTimer in several of the following ways:

[0132] Method 1: When a network device configures ps-wakeup for a terminal device and the terminal device does not detect a DCI scrambled by a PS-RNTI, the terminal device may start a drx-onDurationTimer.

[0133] Method 2: If the network device does not configure ps-wakeup for the terminal device, and the terminal device detects a DCI scrambled by PS-RNTI, and the DCI indicates that the terminal device is to be woken up, the terminal device starts the drx-onDurationTimer.

[0134] Multicast DRX Multicast DRX and unicast DRX are independent. Multicast DRX parameters may be for each G-RNTI and / or G-CS-RNTI (per G-RNTI and / or G-CS-RNTI), and multicast DRX is performed for each G-RNTI and / or G-CS-RNTI (per G-RNTI and / or G-CS-RNTI). Note that there may also be a specific association or interaction between unicast DRX and multicast DRX. For example, when receiving a DCI scrambled by a G-RNTI, the terminal device may also start or restart the drx-HARQ-RTT-TimerDL of the unicast DRX and / or stop the drx-RetransmissionTimerDL of the unicast DRX.

[0135] For one multicast, or for one G-RNTI or G-CS-RNTI, the active time of multicast DRX may include any one or more of the operating time of the drx-onDurationTimerPTM for the G-RNTI or G-CS-RNTI, the operating time of the drx-InactivityTimerPTM for the G-RNTI or G-CS-RNTI, or the operating time of the drx-RetransmissionTimerDL-PTM for the G-RNTI or G-CS-RNTI.

[0136] The multicast DRX function can be described as follows.

[0137] A network device controls multicast DRX operation by configuring any one or more of the following parameters by using RRC messages: drx-onDurationTimerPTM: The period at the beginning of the DRX cycle. The point at which drx-onDurationTimerPTM is started or restarted is calculated based on parameters configured by the base station and formulas specified in the protocol. drx-InactivityTimerPTM: A period after a PDCCH opportunity when new DL transmission scheduling is indicated. For example, a terminal device receives a PDCCH (e.g., a PDCCH scrambled by a G-RNTI or a G-CS-RNTI) indicating that there is a new downlink transmission (i.e., a new transmission scheduling), and the drx-InactivityTimerPTM is started or restarted. drx-RetransmissionTimerDL-PTM: The maximum time period for which a DL retransmission must be received. For example, if drx-HARQ-RTT-TimerDL-PTM expires and the data is not successfully decoded, drx-RetransmissionTimerDL-PTM is started or restarted. And drx-HARQ-RTT-TimerDL-PTM: The minimum length of time until a DL retransmission is expected or until a DL retransmission is expected to be received. For example, the terminal device receives a PDCCH (e.g., a PDCCH scrambled by a G-RNTI or a G-CS-RNTI) indicating a downlink transmission, or the terminal device receives data in a downlink allocation of a multicast configuration, and drx-HARQ-RTT-TimerDL-PTM is started or restarted.

[0138] It should be noted that any one or more of drx-RetransmissionTimerDL, drx-HARQ-RTT-TimerDL, drx-RetransmissionTimerUL, drx-HARQ-RTT-TimerUL, drx-RetransmissionTimerSL, drx-HARQ-RTT-TimerSL, drx-HARQ-RTT-TimerDL-PTM, and drx-RetransmissionTimerDL-PTM are for each HARQ process (per HARQ process). For example, a terminal device maintains different drx-HARQ-RTT-TimerDL for different HARQ processes. For example, a terminal device maintains different drx-RetransmissionTimeUL for different HARQ processes. For example, a terminal device maintains different drx-HARQ-RTT-TimerDL-PTM for different HARQ processes. For example, a terminal device maintains different drx-RetransmissionTimerDL-PTM for different HARQ processes.

[0139] It should be noted that one or both of the drx-HARQ-RTT-TimerDL-PTM and the drx-RetransmissionTimerDL-PTM may be for each G-RNTI and / or G-CS-RNTI (per G-RNTI and / or G-CS-RNTI) or for each multicast / multicast service (per multicast / multicast service). For example, a terminal device maintains different drx-HARQ-RTT-TimerDL-PTMs for different G-RNTIs and / or G-CS-RNTIs or different multicasts / multicast services. For example, a terminal device maintains different drx-RetransmissionTimerDL-PTMs for different G-RNTIs and / or G-CS-RNTIs or different multicasts / multicast services.

[0140] Please note that for DRX-related content, please refer to 3GPP TS 38.321: "NR; Medium Access Control (MAC); Protocol specification", and the details will not be described again here.

[0141] 4. Channel state information (CSI) and channel sounding reference signal (SRS) transmission For example, accurate CSI enables the transmitting end to perform appropriate data processing on the data to be transmitted, such as determining precoding, modulation and coding schemes, thereby improving the efficiency of data transmission and system performance.

[0142] Typically, a terminal device may measure a reference signal transmitted by a network device to obtain CSI and feed the CSI back to the network device so that the network device performs link adaptation for subsequent data transmission.

[0143] For example, the CSI configuration information may be configured by the network device by using dedicated radio resource control (RRC) signaling.

[0144] For example, in wireless communications, SRS is used to estimate uplink channel frequency domain information to perform frequency selective scheduling and to estimate downlink channels to perform downlink beamforming.

[0145] The following briefly describes how the terminal device transmits CSI and SRS to the network device at R15, R16, and R17.

[0146] In R15 (or when DCP monitoring is not configured and a DRX group is not configured), the measures by which the terminal device transmits CSI and SRS in unicast DRX include one or both of the following: (1) If symbol n is not within the DRX valid time, the terminal device does not transmit semi-persistent CSI configured on the PUSCH, the terminal device does not transmit CSI on the PUCCH, or the terminal device does not transmit periodic SRS or semi-persistent SRS. (2) If CSI-masking is configured for the terminal device and the drx-onDurationTimer does not operate for symbol n, the terminal device does not transmit CSI on the PUCCH.

[0147] In R16 (or when DCP monitoring is configured), the strategies for the terminal device to transmit CSI and SRS in unicast DRX include any one or more of the following: (1) If DCP monitoring is configured for the terminal device, and symbol n is within the period of drx-onDurationTimer, and the drx-onDurationTimer in the current DRX cycle is not started, and symbol n is not within the DRX valid time, the terminal device: (1.1) The terminal device does not transmit semi-persistent CSI configured on the PUSCH, and the terminal device does not transmit periodic SRS or semi-persistent SRS; (1.2) If ps-TransmitPeriodicL1-RSRP being true is not configured for the terminal device, and ps-TransmitPeriodicL1-RSRP being true indicates that the terminal device needs to report periodic CSI, which in this case is L1-RSRP, the terminal device does not transmit periodic CSI, which is L1-RSRP, on the PUCCH; and (1.3) If ps-TransmitOtherPeriodicCSI being true is not configured for the terminal device, and ps-TransmitOtherPeriodicCSI being true indicates that the terminal device needs to report non-L1-RSRP periodic CSI in this case, the terminal device does not transmit non-L1-RSRP periodic CSI on the PUCCH. Any one or more of the following may be performed. (2) If DCP monitoring is not configured for the terminal device, or symbol n is not within the period of drx-onDurationTimer, or the drx-onDurationTimer in the current DRX cycle is started and symbol n is not within the DRX validity time, the terminal device does not transmit semi-persistent CSI configured on the PUSCH, the terminal device does not transmit CSI on the PUCCH, or the terminal device does not transmit periodic SRS or semi-persistent SRS. (3) If DCP monitoring is not configured for the terminal device, or symbol n is not within the period of drx-onDurationTimer, or the drx-onDurationTimer in the current DRX cycle is started, and if CSI-masking is configured for the terminal device and the drx-onDurationTimer does not operate for symbol n, the terminal device does not transmit CSI on the PUCCH.

[0148] In R16 (or when a DRX group is configured), other ways in which a terminal device transmits CSI and SRS in unicast DRX include one or both of the following. (1) If symbol n is not within the valid time of one DRX group, in that DRX group, the terminal device does not transmit semi-persistent CSI configured on the PUSCH, the terminal device does not transmit CSI on the PUCCH in the DRX group, or the terminal device does not transmit periodic SRS or semi-persistent SRS in the DRX group. (2) If CSI-masking is configured for a terminal device and the drx-onDurationTimer for one DRX group does not operate for symbol n, the terminal device does not transmit CSI on the PUCCH in the DRX group.

[0149] In R17 (or when there is multicast), the strategies for the terminal device to transmit CSI and SRS include any one or more of the following: (1) If DCP monitoring is configured for the terminal device, symbol n is within the period of drx-onDurationTimer, and the drx-onDurationTimer in the current DRX cycle is not started, if symbol n is not within the validity time of unicast DRX, and if the terminal device is not configured to transmit CSI and / or SRS based on multicast DRX, the terminal device performs any one or more of the following: (1.1) The terminal device does not transmit semi-persistent CSI configured on the PUSCH, and the terminal device does not transmit periodic SRS or semi-persistent SRS; (1.2) If ps-TransmitPeriodicL1-RSRP is true and is not configured for the terminal device, the terminal device does not transmit periodic CSI that is L1-RSRP on the PUCCH; and (1.3) If ps-TransmitPeriodicCSI is true and is not configured for the terminal device, the terminal device does not transmit non-L1-RSRP periodic CSI on the PUCCH. (2) If unicast DCP monitoring is configured for the terminal device, symbol n is within the period of drx-onDurationTimer, and the drx-onDurationTimer in the current DRX cycle is not started, if symbol n is not within the validity time of unicast DRX, if the terminal device is configured to transmit CSI and / or SRS based on multicast DRX, and if symbol n is not within the validity time of all multicast DRX in which the UE participates, and multicast DRX is configured for each multicast in which the UE participates, the terminal device performs any one or more of the following: (2.1) The terminal device does not transmit semi-persistent CSI configured on the PUSCH, and the terminal device does not transmit periodic SRS or semi-persistent SRS; (2.2) If ps-TransmitPeriodicL1-RSRP is true and is not configured for the terminal device, the terminal device does not transmit periodic CSI that is L1-RSRP on the PUCCH; and (2.3) If ps-TransmitPeriodicCSI is true and is not configured for the terminal device, the terminal device does not transmit non-L1-RSRP periodic CSI on the PUCCH. (3) If DCP monitoring is not configured for the terminal device, or symbol n is not within the period of drx-onDurationTimer, or the drx-onDurationTimer in the current DRX cycle is started, if symbol n is not within the validity time of one DRX group, and if the terminal device is not configured to transmit CSI and / or SRS based on multicast DRX, in the DRX group, the terminal device does not transmit semi-persistent CSI configured on the PUSCH, the terminal device does not transmit CSI on the PUCCH in the DRX group, or the terminal device does not transmit periodic SRS and semi-persistent SRS in the DRX group. (4) If DCP monitoring is not configured for the terminal device, or symbol n is not within the period of the drx-onDurationTimer, or the drx-onDurationTimer in the current DRX cycle is started and symbol n is not within the validity time of one DRX group, if the terminal device is configured to transmit CSI and / or SRS based on multicast DRX, and if symbol n is not within the validity time of all multicast DRXs that the UE joins and is associated with the DRX group, and multicast DRX is configured for each multicast that the UE joins and is associated with the DRX group, then in the DRX group, the terminal device does not transmit semi-persistent CSI configured on the PUSCH, the terminal device does not transmit CSI on the PUCCH in the DRX group, or the terminal device does not transmit periodic SRS and semi-persistent SRS in the DRX group. (5) If DCP monitoring is not configured for the terminal device, or symbol n is not within the period of the drx-onDurationTimer, or the drx-onDurationTimer in the current DRX cycle is started, and if the terminal device is not configured to transmit CSI and / or SRS based on multicast DRX, and if CSI-masking is configured for the terminal device and the drx-onDurationTimer for one DRX group does not operate for symbol n, the terminal device does not transmit CSI on the PUCCH in the DRX group.

[0151] 5. Bandwidth Part (BWP) and Common Frequency Resource (CFR)

[0152] For example, BWP may be understood as a subset of the cell bandwidth. For example, BWP may be understood as a portion of the cell bandwidth. For example, the cell bandwidth includes the BWP. For example, BWP may alternatively be equal to the cell bandwidth.

[0153] For example, for one cell, a terminal device may acquire one or more BWP configurations and may perform BWP switching. However, there is only one active BWP at a particular time. The terminal device may perform transmission or reception on the active BWP. For example, for the active BWP, the terminal device may perform any one or more of the following: transmitting on an UL-SCH, transmitting on an RACH, monitoring a PDCCH, transmitting a PUCCH, reporting CSI, transmitting an SRS, receiving a DL-SCH, transmitting a PSBCH, transmitting a PSCCH, transmitting a SL-SCH, transmitting a PSFCH, receiving a PSFCH, receiving a PSBCH, receiving a PSCCH, and receiving a SL-SCH.

[0154] For example, the CFR may be understood as a subset of the cell bandwidth or BWP. For example, the CFR may be understood as a portion of the cell bandwidth or BWP. For example, the cell bandwidth or BWP includes the CFR. For example, the CFR may be equal to the cell bandwidth or BWP.

[0155] For example, for one cell, a terminal device may obtain the configuration of one or more BWPs, and the configuration information of one of the BWPs may include information about the multicast CFR. The terminal device may receive multicast services / data over the multicast CFR. For example, if the configuration message of the terminal device's active BWP includes information about the multicast CFR, the terminal device may include information about the multicast CFR and receive multicast services / data over the BWP or the multicast CFR, or if the configuration message of the terminal device's active BWP does not include information about the multicast CFR, the terminal device cannot receive multicast services / data over the BWP.

[0156] It should be noted that although BWP or CFR is used for purposes of description herein, the name BWP or CFR is not limited to BWP or CFR, or may be another name.

[0157] Problem 1: In the prior art, in the following two scenarios, even if the configuration message of the active BWP of the terminal device does not include information about the multicast CFR, the terminal device transmits CSI and / or SRS. However, if the configuration message of the active BWP of the terminal device does not include information about the multicast CFR, the terminal device cannot (or may not) receive the multicast service / data, or the terminal device does not receive the multicast service / data. It can be understood that transmitting CSI and / or SRS in this case is meaningless and may increase the power consumption of the terminal device. For example, in this scenario, the network device may not perform related multicast scheduling, so the terminal device does not need to transmit CSI and / or SRS. Alternatively, the network device needs to perform related multicast scheduling, but since the terminal device does not receive the multicast service / data, the network device does not need to consider the CSI and / or SRS of the terminal device when performing multicast scheduling, and therefore the terminal device does not need to transmit CSI and / or SRS.

[0158] Scenario 1: Multicast DRX is not configured for some or all of the multicasts in which the end device participates.

[0159] Scenario 2: When the multicast DRX of the multicast that the terminal device joins is within the valid time, or when the drx-onDurationTimerPTM of the multicast that the terminal device joins is activated.

[0160] In view of this, embodiments of the present application provide a communication method and a communication device for transmitting CSI and / or SRS when it is considered whether a BWP configuration message includes information about multicast CFR.

[0161] It should be noted that in the embodiment of the present application, a terminal device is used as an example for explanation. Alternatively, the terminal device may be replaced by a MAC entity of the terminal device, another entity of the terminal device, or another device. This is not limited in the present application.

[0162] In the embodiment of the present application, "not sending" can be understood as "not reporting".

[0163] In the embodiments of the present application, "send" may be understood as "report."

[0164] In the embodiments of the present application, "not belonging to" is understood as "not in" or "not present in".

[0165] In the embodiments of the present application, "belonging to" is understood as "being in" or "being in".

[0166] In the embodiments of the present application, "associated" may be understood as "corresponding."

[0167] In the embodiments of the present application, "not including" may be understood as "not present."

[0168] In the embodiment of the present application, the bandwidth portion may be understood as a bandwidth segment and may be replaced with / .

[0169] In the embodiment of the present application, CFR may be understood as / replaced as multicast CFR or multicast-related CFR.

[0170] In the embodiments of the present application, "start" can be understood as "start" or "restart" and can be replaced with / .

[0171] It should be noted that in the embodiments of the present application, the inclusion of the preset conditions in conditions 1, 2, 3, 4, 5, or 6 may be understood as "if the preset conditions include conditions 1, 2, 3, 4, 5, or 6" or "because the preset conditions include conditions 1, 2, 3, 4, 5, or 6."

[0172] The following describes in detail the communication method provided in the embodiment of the present application with reference to Figure 3. As shown in Figure 3, the method may include step 310.

[0173] 310: If a predetermined condition is met, the terminal device does not transmit first channel state information (CSI) at a first time, and the predetermined condition includes any one or more of condition 1, condition 2, condition 3, condition 4, condition 5, and condition 6.

[0174] Optionally, "satisfying a preset condition" may include the terminal device determining that the preset condition is satisfied.

[0175] 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 embodiments of the present application. For example, the first time may be understood as any one or more of one or more symbols, one or more slots, one or more subframes, one or more frames, etc.

[0176] For example, the first time may be understood as the symbol n. For example, the first time may also be understood as the first instant.

[0177] Note 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 5 is the fifth condition, and condition 6 is the sixth condition.

[0181] It should be noted that in different conditions, the "first CSI" may be different or the same, and / or the "terminal device does not transmit the first CSI at the first time" may be different or the same, which is not limited in this application.

[0182] Condition 1: The first time does not belong to the valid time of the first DRX, and the configuration message of the first BWP does not contain information about CFR.

[0183] The first DRX may be used to control the monitoring of terminal device specific control information.

[0184] It should be noted that the first DRX may also be used to control monitoring of control information that is not terminal device specific control information, which is not limited in this application.

[0185] For example, the first DRX may be used to control monitoring of control information for any one or more of 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-SRS-RNTI), AI-RNTI, sidelink RNTI, SL-RNTI), sidelink configured scheduling RNTI (SLCS-RNTI), and sidelink semi-persistent scheduling V2X RNTI (SL semi-persistent scheduling V-RNTI).

[0186] For example, the first DRX may be a unicast DRX or a DRX group (eg, one DRX group).

[0187] For example, the effective time of the first DRX may include any one or more of the operating time of a duration timer (e.g., drx-onDurationTimer) corresponding to the unicast, the operating time of an inactivity timer (e.g., drx-InactivityTimer) corresponding to the unicast, or the operating time of a retransmission timer corresponding to the unicast.

[0188] For example, the retransmission timer corresponding to unicast may include any one or more of 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).

[0189] For example, a duration timer corresponding to duration timer / unicast indicates the length of time that a terminal device waits to receive control information (eg, DCI) after being woken up.

[0190] For example, an inactivity timer corresponding to inactivity timer / unicast indicates a period of time after newly transmitted data or control information for scheduling a new transmission.

[0191] For example, a retransmission timer corresponding to a retransmission timer / unicast indicates the length of time for which a terminal device receives a retransmission (eg, DCI, data, and resources).

[0192] For example, a downlink retransmission timer corresponding to a downlink retransmission timer / unicast indicates the length of time for a terminal device to receive a downlink retransmission (eg, DCI, data, and resources).

[0193] For example, an uplink retransmission timer corresponding to an uplink retransmission timer / unicast indicates the length of time for which a terminal device receives an uplink retransmission (eg, DCI, data, and resources).

[0194] For example, a sidelink retransmission timer corresponding to a sidelink retransmission timer / unicast indicates the length of time for which a terminal device receives a sidelink retransmission (e.g., DCI, data, and resources).

[0195] For example, the effective time of the first DRX may include any one or more of the operation time of a duration timer (e.g., drx-onDurationTimer) corresponding to the DRX group, the operation time of an inactivity timer (e.g., drx-InactivityTimer) corresponding to the DRX group, or the operation time of a retransmission timer corresponding to the DRX group.

[0196] It should be noted that the effective time of the first DRX may further include other times, which is not limited in this application. For example, for the content of the effective time of the first DRX, please refer to 3GPP TS 38.321: "NR; Medium Access Control (MAC); Protocol specification."

[0197] Optionally, the present application may further include the terminal device obtaining a configuration message of the first BWP. For example, the configuration of the first BWP may be carried in RRC-specific signaling (e.g., an RRC reconfiguration message) or a broadcast message / system information (e.g., SIB1). This is not limited in the present application.

[0198] The first BWP contains the valid BWP.

[0199] Optionally, in the present application, "the configuration message of the BWP does not include information about the CFR" may include that the BWP does not include the CFR.

[0200] For example, the valid BWPs may include the active BWPs, the active BWPs of the terminal device, or all active BWPs of the terminal device.

[0201] For example, the configuration message of the first BWP includes a configuration message corresponding to the first BWP.

[0202] For example, information about a CFR includes CFR-related configuration information.

[0203] For example, "the configuration message of the first BWP does not include information about the CFR" includes that information about the CFR does not exist in the configuration message of the first BWP.

[0204] Optionally, the first BWP may include all valid BWPs. Optionally, the first BWP includes valid BWPs of cells / cell sets corresponding to multicasts in which the terminal device joins or receives. Optionally, the first BWP includes valid BWPs of cells / cell sets corresponding to all multicasts in which the terminal device joins.

[0205] For example, the terminal device corresponds to or operates in multiple cells, and the first BWP includes valid BWPs corresponding to the multiple cells.

[0206] For example, if symbol n is not within the valid time of unicast DRX and the configuration message of each valid BWP does not include information about CFR, the terminal device does not transmit the configured semi-persistent CSI on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH.

[0207] Optionally, the preset condition includes condition 1, and "the terminal device does not transmit the first CSI at the first time" may include the terminal device not transmitting the first CSI at the first time for the first cell set.

[0208] The first cell set includes at least one cell, and the first cell set is associated with a first DRX.

[0209] For example, the first DRX is a DRX group (eg, the first DRX group). The first cell set is a cell set corresponding to the DRX group (eg, the first DRX group).

[0210] Optionally, the first BWP is associated with a first DRX or a first cell set.

[0211] In the present application, "a BWP (e.g., a first BWP or a second BWP) is associated with a first DRX or cell set (e.g., a first cell set)" may be understood as a cell / cell set corresponding to a BWP (e.g., a first BWP or a second BWP) being associated with the first DRX or cell set (e.g., a first cell set).

[0212] Optionally, the first BWP may include all valid BWPs associated with the first DRX or the first cell set. Optionally, the first BWP includes valid BWPs of cells / cell sets corresponding to multicasts that the terminal device joins or receives and that are associated with the first DRX or the first cell set. Optionally, the first BWP includes valid BWPs of cells / cell sets corresponding to all multicasts that the terminal device joins or receives and that are associated with the first DRX or the first cell set.

[0213] For example, the first cell set includes a plurality of cells, and the first BWP includes all valid BWPs corresponding to the plurality of cells.

[0214] For example, if symbol n is not within the validity time of one DRX group and the configuration message of each valid BWP related to that DRX group does not include information about the CFR, then for or in that DRX group, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH.

[0215] It should be noted that "the terminal device does not transmit the first CSI for the first cell set at the first time" may include / be understood as either the terminal device not transmitting CSI (e.g., the first CSI) in the first cell set at the first time or the terminal device not transmitting CSI (e.g., the first CSI) for the first cell set at the first time.

[0216] With regard to "the terminal device does not transmit CSI (e.g., the first CSI) in the first cell set at the first time," it should be noted that this application does not limit whether the terminal device transmits CSI for the first cell set in another cell or cell group.

[0217] With regard to "the terminal device does not transmit CSI (e.g., the first CSI) for the first cell set at the first time," it should be noted that this application does not limit whether the terminal device transmits CSI for another cell or cell set in the first cell set.

[0218] In the description regarding "the terminal device does not transmit the first CSI for the first cell set at the first time," it should be noted that "the first cell set" may be replaced with "may include / be understood as / the first DRX." For example, "for the first cell set" may include / be understood as "for the first DRX." For example, "in the first cell set" may include / be understood as "in the first DRX." For example, "for the first cell set" may include / be understood as "for the first DRX."

[0219] In some embodiments, whether the first time belongs to the valid time of the first DRX may be determined by the terminal device.

[0220] Optionally, the first time not belonging to the valid time of the first DRX includes the terminal device determining that the first time not belongs to the valid time of the first DRX.

[0221] Optionally, the terminal device determining that the first time does not belong to the validity time of the first DRX includes: (1) The terminal device may determine that the first time does not belong to the first DRX validity time based on or in consideration of any one or more of a grant, an allocation, a DRX Command MAC CE, and a Long DRX Command MAC CE received at and / or before the second time, and / or based on or in consideration of a scheduling request transmitted at and / or before the second time; and / or (2) The terminal device may determine, based on or taking into account any one or more of a grant, an allocation, a DRX Command MAC CE, and a Long DRX Command MAC CE received at and / or before the second time, and / or based on or taking into account a scheduling request transmitted at and / or before the second time, that the first time does not belong to the first DRX validity time, and the received grant and allocation may be a grant and allocation received in a first cell set.

[0222] Optionally, the grant includes a unicast related grant.

[0223] Optionally, the allocations include unicast-related allocations.

[0224] Optionally, the DRX Command MAC CE includes a unicast-related DRX Command MAC CE.

[0225] Optionally, the Long DRX Command MAC CE includes a unicast-related Long DRX Command MAC CE.

[0226] Optionally, the scheduling request comprises a unicast-related scheduling request.

[0227] The second time period is determined based on the first time period and the first length of time.

[0228] For example, the interval between the second time and the first time is the first length of time, and the second time occurs before the first time.

[0229] For example, the first time length may be a parameter configured by the network device, or may be calculated according to a formula or algorithm, or may be specified in a protocol. This is not limited in the embodiments of the present application. For example, the first time length is 4 ms.

[0230] Optionally, the preset conditions include condition 1, and the first CSI may be replaced with / may include / may be the second CSI.

[0231] Optionally, the preset condition includes condition 1, and "the terminal device does not transmit the first CSI at the first time" may be replaced with "may include / may be the terminal device does not transmit the second CSI at the first time."

[0232] Optionally, the preset conditions include condition 1, and the preset conditions may further include condition 7.

[0233] Optionally, the preset conditions may include condition 1, and the method in the present application may further include that condition 7 is satisfied.

[0234] Optionally, the preset conditions include condition 1, and the first CSI may be replaced with / may include / may be the third CSI.

[0235] Optionally, the preset condition includes condition 1, and "the terminal device does not transmit the first CSI at the first time" may be replaced with "may include / may be the terminal device does not transmit the third CSI at the first time."

[0236] Optionally, the preset conditions include condition 1, and the preset conditions may further include condition 8.

[0237] Optionally, the preset conditions may include condition 1, and the method in the present application may further include that condition 8 is satisfied.

[0238] Optionally, the preset conditions include condition 1, and the preset conditions may further include condition 9.

[0239] Optionally, the preset conditions may include condition 1, and the method in the present application may further include that condition 9 is satisfied.

[0240] For example, if condition 1, condition 8, and condition 9 are met, the terminal device does not transmit the first CSI or the third CSI at the first time.

[0241] For example, if condition 1, condition 8, and condition 9 are satisfied, the terminal device does not transmit the first CSI or the third CSI at the first time for the first cell set.

[0242] For example, if a DCP is not configured for a terminal device, or symbol n is not within the time length of the duration timer corresponding to unicast, or the duration timer corresponding to unicast is not started or restarted, and symbol n is not within the validity time of a DRX group, and the configuration message of each valid BWP related to that DRX group does not include information about CFR, then for or in that DRX group, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH.

[0243] For example, when DCP is configured for a terminal device, and symbol n is within the time length of the duration timer corresponding to unicast, and the duration timer corresponding to unicast is not started or restarted, if symbol n is not within the valid time of unicast DRX, and if the configuration message of each valid BWP does not contain information about CFR, the terminal device: The terminal device does not transmit semi-persistent CSI configured on the PUSCH; If the terminal device is not configured to report L1-RSRP periodic CSI or CSI, the terminal device does not transmit L1-RSRP periodic CSI on the PUCCH; or If the terminal device is not configured to report non-L1-RSRP periodic CSI or CSI, the terminal device shall not transmit non-L1-RSRP periodic CSI on the PUCCH. Any one or more of the following may be implemented.

[0244] Condition 2: The first time does not belong to the valid time of the first DRX, the configuration message of the second BWP includes information about CFR, and the first time does not belong to the valid time of the second DRX set.

[0245] The second DRX set may include at least one multicast DRX, and the at least one multicast DRX may include the first multicast DRX, and the first multicast DRX may be used to control monitoring of control information related to a third multicast service.

[0246] 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 participates, or a DRX corresponding to a multicast / multicast service received by the terminal device and associated with the second BWP, or a DRX corresponding to a multicast / multicast service in which the terminal device participates and associated with the second BWP.

[0247] "Associated with the second BWP" may include "associated with a cell / set of cells corresponding to the second BWP."

[0248] For example, the second DRX set may include a DRX corresponding to any one / all of the multicast / multicast services received by the terminal device, or a DRX corresponding to any one / all of the multicast / multicast services in which the terminal device participates, or a DRX corresponding to any one / all of the multicast / multicast services received by the terminal device and associated with the second BWP, or a DRX corresponding to any one / all of the multicast / multicast services in which the terminal device participates and associated with the second BWP.

[0249] For example, the second DRX set may be associated with a tenth multicast service set, and the tenth multicast service set may include a third multicast service.

[0250] For example, the tenth multicast service set may include a multicast / multicast service received by the terminal device, or a multicast / multicast service in which the terminal device joins, or a multicast / multicast service received by the terminal device and associated with the second BWP, or a multicast / multicast service in which the terminal device joins and associated with the second BWP.

[0251] For example, the tenth multicast service set may include any one / all of the multicasts / multicast services received by the terminal device, or any one / all of the multicasts / multicast services in which the terminal device participates, or any one / all of the multicasts / multicast services received by the terminal device and associated with the second BWP, or any one / all of the multicasts / multicast services in which the terminal device participates and associated with the second BWP.

[0252] For example, the third 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.

[0253] For example, the control information regarding the third multicast service may include / be understood as control information associated with (or scrambled by) the first G-RNTI and / or the first G-CS-RNTI.

[0254] It should be noted that the first multicast DRX may also be used to control the monitoring of other control information, which is not limited in this application.

[0255] For example, the validity time of multicast DRX may include any one or more of the operation time of a 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).

[0256] For example, a duration timer corresponding to a duration timer / multicast indicates the length of time that a terminal device waits to receive control information (eg, DCI) after being woken up.

[0257] For example, an inactivity timer corresponding to a multicast indicates a period of time after newly transmitted data or control information for scheduling a new transmission.

[0258] For example, a retransmission timer corresponding to a multicast indicates the length of time for a terminal device to receive a retransmission (eg, DCI, data, and resources) corresponding to the multicast.

[0259] For example, the validity time of the first multicast DRX is an operating time of a duration timer (e.g., drx-onDurationTimerPTM) corresponding to the third multicast service (or the first G-RNTI and / or the first G-CS-RNTI); the running time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to the third multicast service (or the first G-RNTI and / or the first G-CS-RNTI); or The operation time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to the third multicast service (or the first G-RNTI and / or the first G-CS-RNTI). may include any one or more of:

[0287] For example, the second DRX set may include all multicast DRXs associated with the first DRX, or all multicast DRXs associated with the first cell set.

[0295] The third time period is determined based on the first time period and the second time period.

The configuration message of the active BWP of cell 1 includes information about the CFR. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 1. Multicast DRX is configured for each of multicast 1 and multicast 2. If the first time is not within the validity time of the first DRX group, the validity time of the multicast DRX corresponding to multicast 1, or the validity time of the multicast DRX corresponding to multicast 2, the terminal device does not transmit the first CSI at the first time for the first DRX group / first cell set, the first DRX is the first DRX group, the ninth multicast service set is multicast 1 and multicast 2, the first cell set is cell 1, cell 2, and cell 3, the tenth cell set is cell 1, and the second BWP is the valid BWP of cell 1.

[0361] For example, if condition 2, condition 7, and condition 14 are met, the terminal device does not transmit the first CSI or the second CSI at the first time for the first cell set.

[0365] For example, if condition 2, condition 8, condition 9, and condition 14 are satisfied, the terminal device does not transmit the first CSI or the third CSI at the first time for the first cell set.

[0366] For example, if a DCP is not configured for the terminal device, or symbol n is not within the time length of the duration timer corresponding to unicast, or the duration timer corresponding to unicast is not started or restarted, or symbol n is not within the validity time of one DRX group, or if the configuration message of the valid BWP related to the DRX group contains information about CFR, and symbol n is not within the validity time of all multicast DRX related to the DRX group, and multicast DRX is configured for each multicast related to the DRX group in which the UE joins, then for or in that DRX group, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH.

[0371] 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 participates, or a DRX corresponding to a multicast / multicast service received by the terminal device and associated with the second BWP, or a DRX corresponding to a multicast / multicast service in which the terminal device participates and associated with the second BWP.

[0372] For example, the third DRX set may be associated with a twelfth multicast service set, which may include a fourth multicast service.

[0373] For example, the twelfth multicast service set may include a multicast / multicast service received by the terminal device, or a multicast / multicast service in which the terminal device joins, or a multicast / multicast service received by the terminal device and associated with a second BWP, or a multicast / multicast service in which the terminal device joins and associated with a second BWP.

[0374] For example, the fourth multicast service may be understood as a multicast service associated with the third G-RNTI and / or the third G-CS-RNTI, or a multicast associated with the third G-RNTI and / or the third G-CS-RNTI.

[0375] For example, control information regarding the fourth multicast service may include / be understood as control information associated with (or scrambled by) the third G-RNTI and / or the third G-CS-RNTI.

[0376] It should be noted that the second multicast DRX may also be used to control the monitoring of other control information, which is not limited in this application.

[0377] For example, the validity time of the second multicast DRX is the operation time of a duration timer (e.g., drx-onDurationTimerPTM) corresponding to the fourth multicast service (or the third G-RNTI and / or the third G-CS-RNTI); the running time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to the fourth multicast service (or the third G-RNTI and / or the third G-CS-RNTI), or The operation time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to the fourth multicast service (or the third G-RNTI and / or the third G-CS-RNTI). may include any one or more of:

[0378] For example, the validity time of the third DRX set may include any one or more of the validity time of the DRX set corresponding to the twelfth multicast service set, the validity time of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the twelfth multicast service set, or the validity time of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the third DRX set.

[0379] For example, the validity time of the third DRX set is The operation time of the drx-onDurationTimerPTM, the operation time of the drx-InactivityTimerPTM, or the operation time of the drx-RetransmissionTimerDL-PTM for the G-RNTI set and / or G-CS-RNTI set corresponding to the third DRX set. may include any one or more of:

[0380] It should be noted that the validity time of the third DRX set may further include other times, which is not limited in this application.

[0381] Optionally, the preset condition includes condition 3, and "the terminal device does not transmit the first CSI at the first time" may include the terminal device not transmitting the first CSI for the second cell set at the first time.

[0382] It should be noted that "the terminal device does not transmit the first CSI for the second cell set at the first time" may include / be understood as either the terminal device not transmitting CSI (e.g., the first CSI) in the second cell set at the first time or the terminal device not transmitting CSI (e.g., the first CSI) for the second cell set at the first time.

[0383] With regard to "the terminal device does not transmit CSI (e.g., the first CSI) in the second cell set at the first time," it should be noted that this application does not limit whether the terminal device transmits CSI for the second cell set in another cell or cell group.

[0384] With regard to "the terminal device does not transmit CSI (e.g., the first CSI) for the second cell set at the first time," it should be noted that this application does not limit whether the terminal device transmits CSI for another cell or cell set in the second cell set.

[0385] The second set of cells includes at least one cell.

[0386] Optionally, the second cell set is not associated with the third DRX set.

[0387] For example, the sixth cell set is associated with the third DRX set or the twelfth multicast service set.

[0388] The sixth cell set includes at least one cell.

[0389] The second cell set not being associated with the third DRX set may be understood as the second cell set not being associated with the twelfth multicast service set / sixth cell set.

[0390] For example, the second cell set may include a cell / cell set other than the cell / cell set associated with the twelfth multicast service set / third DRX set, or a cell / cell set other than the sixth cell set.

[0391] For example, a terminal device includes / has three cells: cell 1, cell 2, and cell 3. The configuration message of the effective BWP of cell 1 includes information about the CFR. The terminal device receives multicast 1 in cell 1. If the first time is not within the valid time of unicast DRX but is within the valid time of multicast DRX corresponding to multicast 1, the terminal device does not transmit the first CSI at the first time for cells 2 and 3, the first DRX is unicast DRX, the third DRX set is multicast DRX corresponding to multicast 1, the second cell set is cell 2 and cell 3, the sixth cell set is cell 1, and the second BWP is the effective BWP of cell 1.

[0392] For example, if symbol n is not within the validity time of unicast DRX, if the configuration message of the valid BWP includes information about CFR, and if symbol n is within the validity time of multicast DRX in which the terminal device participates, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or does not transmit CSI on the PUCCH for cells or cell sets other than the cell related to the multicast (e.g., the cell related to the multicast such that symbol n is within the validity time of multicast DRX).

[0393] Optionally, the second set of cells is not associated with the first set of multicast services.

[0394] The first set of multicast services includes at least one multicast service, and the at least one multicast service includes a fifth multicast service.

[0395] For example, the first multicast service set may include a multicast / multicast service received by the terminal device, or a multicast / multicast service in which the terminal device joins, or a multicast / multicast service received by the terminal device and associated with a second BWP, or a multicast / multicast service in which the terminal device joins and associated with a second BWP.

[0396] For example, the first set of multicast services may include a multicast / multicast service received by the terminal device and for which multicast DRX is not configured, or a multicast / multicast service joined by the terminal device and for which multicast DRX is not configured, or a multicast / multicast service received by the terminal device and associated with a second BWP and for which multicast DRX is not configured, or a multicast / multicast service joined by the terminal device and associated with a second BWP and for which multicast DRX is not configured, or a multicast / multicast service associated with a second BWP and for which multicast DRX is not configured.

[0397] For example, the first multicast service set may include any one or more / all of the multicast / multicast services received by the terminal device and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services joined by the terminal device and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services received by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services joined by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services associated with the second BWP and for which multicast DRX is not configured.

[0398] For example, the eighth cell set is associated with the first multicast service set.

[0399] The eighth cell set includes at least one cell.

[0400] For example, the second cell set not being associated with the first multicast service set may be understood as the second cell set not being associated with the eighth cell set.

[0401] For example, the second cell set may include a cell / cell set other than the cell / cell set associated with the first multicast service set, or a cell / cell set other than the eighth cell set.

[0402] For example, a terminal device includes / has three cells: cell 1, cell 2, and cell 3. The configuration message of the valid BWP of cell 1 includes information about CFR. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 1. Multicast DRX is configured for multicast 1, and no multicast DRX is configured for multicast 2. If the first time is neither within the valid time of unicast DRX nor within the valid time of multicast DRX corresponding to multicast 1, the terminal device does not transmit the first CSI at the first time for cell 3 and cell 2, the first DRX is unicast DRX, the second cell set is cell 3 and cell 2, and the eighth cell set is cell 1.

[0403] For example, if symbol n is not within the validity time of unicast DRX, the configuration message of the valid BWP includes information about CFR, and there is a multicast for which multicast DRX is not configured, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH for cells or cell sets other than the cells related to the multicast for which multicast DRX is not configured.

[0404] For example, the second cell set may include cells / cell sets other than the cells / cell sets associated with the 12th multicast service set / third DRX set and the cells / cell sets associated with the first multicast service set, or cells / cell sets other than the sixth cell set and the eighth cell set.

[0405] For example, a terminal device includes / has three cells: cell 1, cell 2, and cell 3. The configuration messages of the valid BWPs of cell 1 and cell 2 include information about CFR. 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 no multicast DRX is configured for multicast 2. If the first time is not within the valid time of unicast DRX but is within the valid time of multicast DRX corresponding to multicast 1, the terminal device does not transmit the first CSI at the first time for cell 3, the first DRX is unicast DRX, the third DRX set is multicast DRX corresponding to multicast 1, the second cell set is cell 3, the sixth cell set is cell 1, and the eighth cell set is cell 2.

[0406] For example, if symbol n is not within the validity time of unicast DRX and the configuration message of the valid BWP contains information about CFR, if symbol n is within the validity time of multicast DRX in which the terminal device participates, and if there is a multicast for which multicast DRX is not configured, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or does not transmit CSI on the PUCCH to cells or cell sets other than the cell related to the multicast (e.g., the cell related to the multicast for which multicast DRX is not configured) and the cell related to the multicast for which multicast DRX is not configured.

[0407] Optionally, the second cell set is associated with the first DRX / first cell set.

[0408] For example, the association of a second cell set with a first DRX may be understood as the same DRX parameters (e.g., parameters relating to the first DRX) being used for the cells included in the second cell set, and the reception of control information for the cells included in the second cell set being controlled by the same DRX (e.g., the first DRX).

[0409] Optionally, the third DRX set / sixth cell set is associated with the first DRX / first cell set.

[0410] For example, the association of a sixth cell set with the first DRX may be understood as the same DRX parameters (e.g., parameters relating to the first DRX) being used for the cells included in the sixth cell set, and the reception of control information for the cells included in the sixth cell set being controlled by the same DRX (e.g., the first DRX).

[0411] Optionally, the first set of cells includes the second set of cells.

[0412] For example, the second set of cells is a subset of the first set of cells, or the second set of cells is equal to the first set of cells.

[0413] Optionally, the first set of cells includes a sixth set of cells.

[0414] 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.

[0415] Optionally, the first set of cells includes the second set of cells and the sixth set of cells.

[0416] For example, the second cell set and the sixth cell set are equal to the first cell set.

[0417] For example, there is no intersection between the second set of cells and the sixth set of cells.

[0418] For example, the third DRX set may include a DRX corresponding to a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX, or 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, or a DRX corresponding to a multicast / multicast service received by the terminal device and associated with the second BWP, or a DRX corresponding to a multicast / multicast service in which the terminal device participates and associated with the second BWP, or a DRX corresponding to a multicast / multicast service associated with the second BWP.

[0419] For example, the twelfth multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX, or 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, or a multicast / multicast service received by the terminal device and associated with the second BWP, or a multicast / multicast service in which the terminal device joins and associated with the second BWP.

[0420] For example, the second cell set may include a cell / cell set other than the cell / cell set associated with the 12th multicast service set / third DRX set in the first cell set, or a cell / cell set other than the sixth cell set.

[0421] For example, a terminal device includes / has two DRX groups, where the first DRX group corresponds to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, cell 4, cell 5, and cell 6. The configuration message of the effective BWP of cell 1 includes information about the CFR. The terminal device receives multicast 1 in cell 1. If the first time is not within the valid time of the first DRX group but is within the valid time of the multicast DRX corresponding to multicast 1, the terminal device does not transmit the first CSI at the first time for cells other than cell 1 in the first cell set (i.e., cells 2 and 3), 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 second cell set is cell 2 and cell 3, the sixth cell set is cell 1, and the second BWP is the effective BWP of cell 1.

[0422] Optionally, the first multicast service set / eighth cell set is associated with the first DRX / first cell set.

[0423] For example, the first multicast service set may include a multicast / multicast service received by the terminal device and associated with the first cell set / first DRX, for which multicast DRX is not configured, or a multicast / multicast service joined by the terminal device and associated with the first cell set / first DRX, for which multicast DRX is not configured, or a multicast / multicast service associated with the first cell set / first DRX, for which multicast DRX is not configured, or a multicast / multicast service received by the terminal device and associated with the second BWP, for which multicast DRX is not configured, or a multicast / multicast service joined by the terminal device and associated with the second BWP, for which multicast DRX is not configured, or a multicast / multicast service associated with the second BWP, for which multicast DRX is not configured.

[0424] For example, the first multicast service set may include any one or more / all of the 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, or any one or more / all of the 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 of the multicast / multicast services associated with the first cell set / first DRX and for which multicast DRX is not configured, any one or more / all of the multicast / multicast services received by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services joined by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services associated with the second BWP and for which multicast DRX is not configured.

[0425] For example, the association of the first multicast service set / eighth cell set with the first DRX / first cell set may be understood as the same DRX parameters (e.g., parameters relating to the first DRX) being used for the cells included in the eighth cell set, and the reception of control information for the cells included in the eighth cell set being controlled by the same DRX (e.g., the first DRX).

[0426] Optionally, the first set of cells includes an eighth set of cells.

[0427] 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.

[0428] Optionally, the first set of cells includes the second set of cells and the eighth set of cells.

[0429] For example, the second cell set and the eighth cell set are equal to the first cell set.

[0430] For example, there is no intersection between the second cell set and the eighth cell set.

[0431] For example, the second cell set may include a cell / cell set in the first cell set other than the cell / cell set associated with the first multicast service set, or a cell / cell set other than the eighth cell set.

[0432] For example, a terminal device includes / has two DRX groups, where the first DRX group corresponds to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, cell 4, cell 5, and cell 6. The configuration message of the active BWP of cell 1 includes information about CFR. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 1. Multicast DRX is configured for multicast 1, and no multicast DRX is configured for multicast 2. If the first time is not within the validity time of the first DRX group or the validity time of the multicast DRX corresponding to multicast 1, the terminal device does not transmit the first CSI at the first time for cells other than cell 1 in the first cell set (i.e., cell 3 and cell 1), 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 second cell set is cell 3 and cell 1, and the eighth cell set is cell 2.

[0433] For example, if symbol n is not within the validity time of one DRX group, and the configuration message of the valid BWP associated with the DRX group contains information about CFR, and there is a multicast associated with the DRX group for which multicast DRX is not configured, then the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH for cells or cell sets other than the cells associated with the multicast for which multicast DRX is not configured on / in the DRX group.

[0434] Optionally, the first set of cells includes the second set of cells, the sixth set of cells, and the eighth set of cells. Alternatively, optionally, the first set of cells includes the union of the sixth set of cells, the eighth set of cells, and the second set of cells.

[0435] For example, the second cell set, the sixth cell set, and the eighth cell set are equal to the first cell set.

[0436] For example, there is no intersection between the second cell set and the eighth cell set.

[0437] For example, there is no intersection between the second cell set and the union of the sixth and eighth cell sets.

[0438] It should be noted that there may be an intersection between the sixth set of cells and the eighth set of cells, or there may be no intersection between the sixth set of cells and the eighth set of cells, and this is not a limitation in the present application.

[0439] It should be noted that the sixth set of cells may be the same as or different from the eighth set of cells, and this is not a limitation in the present application.

[0440] For example, the second cell set may include, in the first cell set, cells / cell sets other than the cells / cell sets associated with the 12th multicast service set / third DRX set and the cells / cell sets associated with the first multicast service set, or cells / cell sets other than the sixth cell set and the eighth cell set.

[0441] For example, if symbol n is not within the validity time of a DRX group, if the configuration message of the valid BWP associated with the DRX group contains information about CFR, if symbol n is within the validity time of multicast DRX associated with the DRX group in which the terminal device participates, or if there is a multicast associated with the DRX group for which multicast DRX is not configured, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit 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 validity time of multicast DRX) and the cell associated with the multicast for which multicast DRX is not configured on / in the DRX group.

[0442] For example, the terminal device may transmit the first CSI or CSI at the first time for a cell set or cell other than the second cell set (e.g., the sixth cell set and / or the eighth cell set). For example, in a cell or cell set associated with the first 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 fifth multicast service, the terminal device may transmit the first CSI at the first time.

[0443] In some embodiments, whether the first time belongs to the validity time of the third DRX set may be determined by the terminal device.

[0444] Optionally, the first time belongs to the validity time of the third DRX set includes the terminal device determining that the first time belongs to the validity time of the third DRX set.

[0445] Optionally, the terminal device determining that the first time belongs to the validity time of the third DRX set includes: (1) The terminal device determines that the first time period belongs to the validity time of the third DRX set based on or in consideration of one or both of an allocation (e.g., a received multicast-related allocation) and a multicast-related DRX Command MAC CE received at and / or before the fourth time period; and / or (2) The terminal device may determine, based on or in consideration of either or both of an allocation (e.g., a received multicast-related allocation) and a multicast-related DRX Command MAC CE received at and / or before the fourth time, that the first time does not belong to the validity time of the third DRX set.

[0446] 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 a received assignment related to the twelfth multicast service set.

[0447] 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 for the twelfth multicast service set.

[0448] The fourth time period is determined based on the first time period and the third time period.

[0449] For example, the interval between the fourth time and the first time is a third length of time, and the fourth time occurs before the first time.

[0450] Similarly, the third time period may be a parameter configured by the network device, or may be calculated according to a formula or algorithm, or may be specified in a protocol. This is not limited in the embodiments of the present application. For example, the third time period is 4 ms.

[0451] It should be understood that the fourth time period may be the same as or different from the second time period, which is not limited in the embodiments of the present application.

[0452] It should be noted that the third time length may be the same as or different from the first time length, which is not limited in the embodiments of the present application.

[0466] Optionally, the preset conditions include condition 3, and the method in the present application may further include that condition 9 is satisfied.

[0467] For example, if condition 3, condition 8, and condition 9 are satisfied, the terminal device does not transmit the first CSI or the fifth CSI at the first time.

[0468] For example, if condition 3, condition 8, and condition 9 are satisfied, the terminal device does not transmit the first CSI or the fifth CSI at the first time for the second cell set.

[0469] Condition 4: The first timer does not operate at the first time, and the configuration message of the first BWP does not include information about the CFR. During the operation time of the first timer, the terminal device monitors control information specific to the terminal device.

[0470] During the operation time of the first timer, the terminal device may also monitor control information that is not specific to the terminal device, which is not limited in the present application.

[0471] For example, at the operating time of the first timer, the terminal device may monitor control information scrambled by 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, and SL Semi-Persistent Scheduling V-RNTI.

[0479] Optionally, the terminal device determining that the first timer does not run comprises: (1) the terminal device determines that the first timer does not run based on or in consideration of any one or more of a grant, an allocation, a DRX Command MAC CE, and a Long DRX Command MAC CE received at and / or before the seventh time, and / or based on or in consideration of a scheduling request transmitted at and / or before the seventh time; and / or (2) The terminal device may include determining that the first timer does not operate based on or in consideration of any one or more of a grant, an allocation, a DRX Command MAC CE, and a Long DRX Command MAC CE received at and / or before the seventh time, and / or based on or in consideration of a scheduling request transmitted at and / or before the seventh time, wherein the received grant and allocation may be a grant and allocation received in a first cell set.

[0480] Optionally, the grant includes a unicast related grant.

[0481] Optionally, the allocations include unicast-related allocations.

[0482] Optionally, the DRX Command MAC CE includes a unicast-related DRX Command MAC CE.

[0483] Optionally, the Long DRX Command MAC CE includes a unicast-related Long DRX Command MAC CE.

[0484] Optionally, the scheduling request comprises a unicast-related scheduling request.

[0485] The seventh time period is determined based on the first time period and the sixth time period.

[0486] For example, the interval between the seventh time and the first time is a sixth time length, and the seventh time occurs before the first time.

[0487] It should be understood that the sixth period of time may be a parameter configured by the network device, or may be calculated according to a formula or algorithm, or may be specified in a protocol. This is not limited in the embodiments of the present application. For example, the sixth period of time is 4 ms.

[0488] Optionally, the preset condition includes condition 4, and the first CSI may be replaced with / may include / may be the sixth CSI.

[0489] Optionally, the preset condition includes condition 4, and "the terminal device does not transmit the first CSI at the first time" may be replaced with "may include / may be the terminal device does not transmit the sixth CSI at the first time."

[0490] Optionally, the preset conditions include condition 4, and the preset conditions may further include condition 7.

[0491] Optionally, the preset conditions may include condition 4, and the method in the present application may further include that condition 7 is satisfied.

[0492] Optionally, the preset conditions include condition 4, and the preset conditions may further include condition 10.

[0493] Optionally, the preset conditions include condition 4, and the method in the present application may further include that condition 10 is satisfied.

[0494] For example, if condition 4, condition 7, and condition 10 are met, the terminal device does not transmit the first CSI or the sixth CSI at the first time.

[0495] For example, if condition 4, condition 7, and condition 10 are met, the terminal device does not transmit the first CSI or the sixth CSI at the first time for the first cell set.

[0496] For example, if CSI masking is configured for a terminal device, if the duration timer corresponding to unicast does not run for symbol n, and if the configuration message for each valid BWP does not include information about CFR, the terminal device does not transmit CSI on the PUCCH.

[0497] For example, if CSI masking is configured for a terminal device, if the duration timer corresponding to one DRX group does not run for symbol n, and if the configuration message of each active BWP associated with the DRX group does not include information about CFR, the terminal device will not transmit CSI on the PUCCH for or in the DRX group.

[0498] For example, if DCP is not configured for the terminal device, or symbol n is not within the time length of the duration timer corresponding to unicast, or the duration timer corresponding to unicast is started or restarted, if CSI masking is configured for the terminal device, if the duration timer corresponding to one DRX group does not run for symbol n, and if the configuration message of each valid BWP associated with the DRX group does not include information about CFR, the terminal device does not transmit CSI on the PUCCH for or in the DRX group.

[0499] Condition 5: The first timer does not operate at the first time, the configuration message of the second BWP includes information about the CFR, and the second timer set does not operate at the first time.

[0500] The second timer set includes at least one multicast timer, and the at least one multicast timer includes the first multicast timer. During the operation time of the first multicast timer, the terminal device monitors control information related to the seventh multicast service.

[0501] For example, the multicast timer may be a duration timer corresponding to multicast (eg, drx-onDurationTimerPTM) or a duration timer for multicast DRX (eg, drx-onDurationTimerPTM).

[0502] For example, the second timer set 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, or a multicast timer corresponding to a multicast / multicast service received by the terminal device and associated with the second BWP, or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins and associated with the second BWP.

[0503] For example, the second timer set may include multicast timers corresponding to any one / all of the multicasts / multicast services received by the terminal device, or multicast timers corresponding to any one / all of the multicasts / multicast services in which the terminal device joins, or multicast timers corresponding to any one / all of the multicasts / multicast services received by the terminal device and associated with the second BWP, or multicast timers corresponding to any one / all of the multicasts / multicast services in which the terminal device joins and associated with the second BWP.

[0504] For example, the second timer set may be associated with a thirteenth multicast service set, and the thirteenth multicast service set may include a seventh multicast service.

[0505] For example, the thirteenth multicast service set may include multicast / multicast services received by the terminal device or multicast / multicast services in which the terminal device joins.

[0506] For example, the thirteenth multicast service set may include any one / all of the multicasts / multicast services received by the terminal device, or any one / all of the multicasts / multicast services in which the terminal device joins.

[0507] For example, the seventh multicast service may be understood as a multicast service associated with the fourth G-RNTI and / or the fourth G-CS-RNTI, or a multicast associated with the fourth G-RNTI and / or the fourth G-CS-RNTI.

[0508] For example, control information regarding the seventh multicast service may include / be understood as control information associated with (or scrambled by) the fourth G-RNTI and / or the fourth G-CS-RNTI.

[0509] It should be noted that during the operation time of the first multicast timer, the terminal device may also monitor other control information, which is not limited in this application.

[0510] For example, the first multicast timer may be a timer for the seventh multicast service, or a drx-onDurationTimerPTM for the seventh multicast service, or a timer for the fourth G-RNTI1 and / or the fourth G-CS-RNTI, or a drx-onDurationTimerPTM for the fourth G-RNTI and / or the fourth G-CS-RNTI.

[0511] Optionally, the preset condition includes condition 5, and "the terminal device does not transmit the first CSI at the first time" may include the terminal device not transmitting the first CSI at the first time for the first cell set.

[0512] The first set of cells is associated with a first timer.

[0513] For example, the first timer is a duration timer (eg, drx-onDurationTimer) corresponding to one DRX group (eg, the first DRX group).

[0514] It should be understood that for a related description of "the terminal device does not transmit the first CSI for the first cell set at the first time," reference is made to the related description above. For the sake of brevity, the details will not be described again.

[0515] Please note that for the content of the second BWP, please refer to the explanation of condition 2. The details will not be explained again here.

[0516] Optionally, the second BWP may include one or more valid BWPs for the second timer set or the fifth cell set.

[0517] Optionally, the second timer set is associated with the first cell set, or the first DRX, or the first timer.

[0518] The first set of cells may be understood to include the fifth set of cells.

[0519] For example, the fifth set of cells is a subset of the first set of cells, or the fifth set of cells is equal to the first set of cells.

[0520] A fifth set of cells is associated with the second set of timers, the fifth set of cells including at least one cell.

[0521] 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, or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins 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, or a multicast timer corresponding to a multicast / multicast service received by the terminal device and associated with the second BWP, or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins and associated with the second BWP, or a multicast timer corresponding to a multicast / multicast service associated with the second BWP.

[0522] For example, the second timer set may include a multicast timer corresponding to any one / all of the multicast / multicast services received by the terminal device and associated with the first cell set / first timer / first DRX, or a multicast timer corresponding to any one / all of the multicast / multicast services in which the terminal device joins and associated with the first cell set / first timer / first DRX, or a multicast timer corresponding to any one / all of the multicast / multicast services associated with the first cell set / first timer / first DRX, or a multicast timer corresponding to any one / all of the multicast / multicast services received by the terminal device and associated with the second BWP, or a multicast timer corresponding to any one / all of the multicast / multicast services in which the terminal device joins and associated with the second BWP, or a multicast timer corresponding to any one / all of the multicast / multicast services associated with the second BWP.

[0523] For example, the thirteenth 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, or a multicast / multicast service in which the terminal device joins 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.

[0524] For example, the thirteenth multicast service set may include any one / all of the multicast / multicast services received by the terminal device and associated with the first cell set / first timer / first DRX, or any one / all of the multicast / multicast services in which the terminal device joins and associated with the first cell set / first timer / first DRX, or any one / all of the multicast / multicast services associated with the first cell set / first timer / first DRX.

[0525] For example, the second timer set is a set of multicast timers 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.

[0526] For example, a terminal device includes / has two DRX groups, where the first DRX group corresponds to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, cell 4, cell 5, and cell 6. The configuration message of the effective BWP of cell 1 includes information about the CFR. The terminal device receives multicast 1 in cell 1. If the timer of the first DRX group does not run at the first time and the timer of the multicast DRX corresponding to multicast 1 does not run at the first time, the terminal device does not transmit the first CSI at the first time for the first DRX group / first cell set, 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, the first cell set is cell 1, cell 2, and cell 3, the fifth cell set is cell 1, and the second BWP is the effective BWP of cell 1.

[0527] In some embodiments, whether the second timer set operates at the first time may be determined by the terminal device.

[0528] Optionally, the second timer set not operating at the first time includes the terminal device determining that the second timer set does not operate at the first time.

[0529] Optionally, the terminal device determining that the second timer set does not run comprises: (1) the terminal device determines that the second timer set does not operate based on or in consideration of one or both of an assignment (e.g., a received multicast-related assignment) and a multicast-related DRX Command MAC CE received at and / or before the eighth time; and / or (2) The method may include the terminal device determining, based on or in consideration of one or both of an assignment (e.g., a received multicast-related assignment) and a multicast-related DRX Command MAC CE received at and / or before the eighth time, that the second timer set does not operate, where the received assignment (e.g., the received multicast-related assignment) may be an assignment received in the fifth cell set or the first cell set, and / or a received assignment for the thirteenth multicast service set. Optionally, the multicast-related DRX Command MAC CE may be a multicast-related DRX Command MAC CE received in the fifth cell set and / or a DRX Command MAC CE for the thirteenth multicast service set.

[0530] The eighth time period is determined based on the first time period and the seventh time period.

[0531] For example, the interval between the eighth time and the first time is a seventh time length, and the eighth time occurs before the first time.

[0532] It should be understood that the seventh period of time may be a parameter configured by the network device, or may be calculated according to a formula or algorithm, or may be specified in a protocol. This is not limited in the embodiments of the present application. For example, the seventh period of time is 4 ms.

[0533] Optionally, the preset condition includes condition 5, and the first CSI may be replaced with / may include / may be the sixth CSI.

[0534] The sixth 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:

[0535] Optionally, the preset condition includes condition 5, and "the terminal device does not transmit the first CSI at the first time" may be replaced with "may include / may be the terminal device does not transmit the sixth CSI at the first time."

[0536] Optionally, the terminal device not transmitting the sixth CSI at the first time includes: The terminal device does not transmit semi-persistent CSI; The terminal device does not transmit periodic CSI; The terminal device does not transmit CSI configured on the PUSCH; The terminal device does not transmit semi-persistent CSI configured on the PUSCH; The terminal device does not transmit configured CSI on the PUCCH; The terminal device does not transmit periodic CSI configured on the PUCCH; The terminal device does not transmit semi-persistent CSI configured on the PUCCH; The terminal device does not transmit CSI on the PUCCH; The terminal device does not transmit periodic CSI on the PUCCH; The terminal device does not transmit semi-persistent CSI on the PUCCH; The terminal device does not transmit CSI on the PUSCH, or The terminal device does not transmit semi-persistent CSI on the PUSCH. may include any one or more of:

[0537] For example, if condition 5 is met, the terminal device does not transmit the first CSI or the sixth CSI at the first time.

[0538] For example, if condition 5 is met, the terminal device does not transmit the first CSI or the sixth CSI at the first time for the first cell set.

[0539] For example, if the duration timer corresponding to unicast does not run for symbol n, if the configuration message of the valid BWP includes information about CFR, and if the k duration timer corresponding to multicast does not run for symbol n, the terminal device does not transmit CSI on the PUCCH.

[0540] For example, if the duration timer corresponding to one DRX group does not run for symbol n, if the configuration message of the active BWP associated with the DRX group contains information about CFR, and if each duration timer corresponding to a multicast associated with the DRX group does not run for symbol n, the terminal device does not transmit CSI on the PUCCH for or in the DRX group.

[0541] Optionally, the preset conditions include condition 5, and the preset conditions may further include condition 7.

[0542] Optionally, the preset conditions may include condition 5, and the method in the present application may further include condition 7 being satisfied.

[0543] Optionally, the preset conditions include condition 5, and the preset conditions may further include condition 10.

[0544] Optionally, the preset conditions may include condition 5, and the method in the present application may further include condition 10 being satisfied.

[0545] Condition 10 may include the terminal device obtaining first information.

[0546] The first information may indicate any one or more of: that the terminal device transmits CSI at the operating time of a unicast timer (e.g., the first timer) and / or the operating time of a multicast timer; that the terminal device is restricted to transmitting CSI at the operating time of a unicast timer (e.g., the first timer) and / or the operating time of a multicast timer; or that the terminal device transmits CSI only at the operating time of a unicast timer (e.g., the first timer) and / or the operating time of a multicast timer.

[0547] For example, the unicast timer may / may include a duration timer corresponding to the unicast (eg, drx-onDurationTimer) and / or a duration timer corresponding to the DRX group (eg, drx-onDurationTimer).

[0548] "Transmitting CSI at the operation time of a unicast timer (e.g., a first timer) and / or the operation time of a multicast timer" may include / be understood as any one or more of transmitting CSI on a PUCCH at the operation time of a unicast timer (e.g., a first timer) and / or transmitting CSI on a PUCCH at the operation time of a multicast timer.

[0549] For example, the first information may be transmitted by the network device. For example, the network device may transmit the first information to the terminal device by using an RRC message.

[0550] For example, the first information may be CSI-mask information (or referred to as CSI masking information or CSI-masking information). The CSI-mask information may indicate to the terminal device to transmit CSI at the activation time of the drx-onDurationTimer and / or the activation time of the drx-onDurationTimerPTM.

[0551] Correspondingly, when the terminal device acquires the first information, the terminal device does not transmit CSI or does not transmit CSI on the PUCCH during an effective time other than the operation time of the unicast timer and / or the operation time of the multicast timer, or during a time other than the operation time of the unicast timer and / or the operation time of the multicast timer.

[0552] Please note that "the terminal device acquires the first information" may include / be replaced with a CSI-mask being configured for the terminal device.

[0553] Please note that "the terminal device does not acquire the first information" may include that a CSI-mask is not configured for the terminal device / may be replaced with " / ".

[0554] For example, if condition 5, condition 7, and condition 10 are met, the terminal device does not transmit the first CSI or the sixth CSI at the first time.

[0555] For example, if condition 5, condition 7, and condition 10 are satisfied, the terminal device does not transmit the first CSI or the sixth CSI at the first time for the first cell set.

[0556] Optionally, the preset conditions include condition 5, and the preset conditions may further include condition 14.

[0557] Optionally, the preset conditions include condition 5, and the method in the present application may further include condition 14 being satisfied.

[0558] For example, if condition 5, condition 7, and condition 14 are satisfied, the terminal device does not transmit the first CSI or the sixth CSI at the first time.

[0559] For example, if condition 5, condition 7, and condition 14 are satisfied, the terminal device does not transmit the first CSI or the sixth CSI at the first time for the first cell set.

[0560] For example, if condition 5, condition 10, and condition 14 are satisfied, the terminal device does not transmit the first CSI or the sixth CSI at the first time.

[0561] For example, if condition 5, condition 10, and condition 14 are satisfied, the terminal device does not transmit the first CSI or the sixth CSI at the first time for the first cell set.

[0562] For example, if condition 5, condition 7, condition 10, and condition 14 are satisfied, the terminal device does not transmit the first CSI or the sixth CSI at the first time.

[0563] For example, if condition 5, condition 7, condition 10, and condition 14 are satisfied, the terminal device does not transmit the first CSI or the sixth CSI at the first time for the first cell set.

[0564] For example, if DCP is not configured for the terminal device, or symbol n is not within the time length of the duration timer corresponding to unicast, or the duration timer corresponding to unicast is started or restarted, if CSI masking is configured for the terminal device, if a duration timer corresponding to one DRX group does not run for symbol n, if the configuration message of an active BWP related to the DRX group includes information about CFR, or if each duration timer corresponding to multicast related to the DRX group does not run for symbol n and multicast DRX is configured for each multicast associated with the DRX group that the UE joins, the terminal device does not transmit CSI on the PUCCH for or in the DRX group.

[0565] Condition 6: Includes conditions C and D.

[0566] Condition C: The first timer does not operate at the first time, and the configuration message of the second BWP includes information about the CFR.

[0567] Condition D: The third timer set runs at the first time and / or there is no multicast DRX configured for the second multicast service set.

[0568] The third timer set may include at least one multicast timer, and the at least one multicast timer may include a second multicast timer. During the operation time of the second multicast timer, the terminal device may monitor control information related to the eighth multicast service.

[0569] For example, the third timer set 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, or a multicast timer corresponding to a multicast / multicast service received by the terminal device and associated with the second BWP, or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins and associated with the second BWP.

[0570] For example, the third timer set may be associated with the fourteenth multicast service set, and the fourteenth multicast service set may include the eighth multicast service.

[0571] For example, the fourteenth multicast service set may include a multicast / multicast service received by the terminal device, or a multicast / multicast service in which the terminal device participates, or a multicast / multicast service received by the terminal device and associated with a second BWP, or a multicast / multicast service in which the terminal device participates and associated with a second BWP.

[0572] For example, the eighth multicast service may be understood as a multicast service associated with the fifth G-RNTI and / or the fifth G-CS-RNTI, or a multicast associated with the fifth G-RNTI and / or the fifth G-CS-RNTI.

[0573] For example, control information regarding the eighth multicast service may include / be understood as control information associated with (or scrambled by) the fifth G-RNTI and / or the fifth G-CS-RNTI.

[0574] It should be noted that during the operation time of the second multicast timer, the terminal device may also monitor other control information, which is not limited in this application.

[0575] For example, the second multicast timer may be a timer for the eighth multicast service, or a drx-onDurationTimerPTM for the eighth multicast service, or a timer for the fifth G-RNTI and / or the fifth G-CS-RNTI, or a drx-onDurationTimerPTM for the fifth G-RNTI and / or the fifth G-CS-RNTI.

[0576] Optionally, the preset condition includes condition 6, and "the terminal device does not transmit the first CSI at the first time" may include the terminal device not transmitting the first CSI at the first time for the third cell set.

[0577] It should be noted that "the terminal device does not transmit the first CSI for the third cell set at the first time" may include / be understood as either the terminal device not transmitting CSI (e.g., the first CSI) in the third cell set at the first time or the terminal device not transmitting CSI (e.g., the first CSI) for the third cell set at the first time.

[0578] With regard to "the terminal device does not transmit CSI (e.g., the first CSI) in the third cell set at the first time," it should be noted that this application does not limit whether the terminal device transmits CSI for the third cell set in another cell or cell group.

[0579] With regard to "the terminal device does not transmit CSI (e.g., the first CSI) for the third cell set at the first time," it should be noted that this application does not limit whether the terminal device transmits CSI for another cell or cell set in the third cell set.

[0580] The third set of cells includes at least one cell.

[0581] Optionally, the third set of cells is not associated with a third set of timers.

[0582] For example, the seventh cell set is associated with the third timer set or the fourteenth multicast service set.

[0583] The seventh cell set includes at least one cell.

[0584] It should be understood that the third cell set not being associated with the third timer set can be understood as the third cell set not being associated with the 14th multicast service set / 7th cell set.

[0585] For example, the third cell set may include a cell / cell set other than the cell / cell set associated with the fourteenth multicast service set / third timer set, or a cell / cell set other than the seventh cell set.

[0586] For example, a terminal device includes / has three cells: cell 1, cell 2, and cell 3. The terminal device receives multicast 1 in cell 1. If a duration timer corresponding to unicast does not operate at the first time but a duration timer corresponding to multicast 1 operates at the first time, the terminal device does not transmit a first CSI for cells 2 and 3 at the first time, the first timer is a duration timer corresponding to unicast, the third timer set is a duration timer corresponding to multicast 1, the third cell set is cell 2 and cell 3, and the seventh cell set is cell 1.

[0587] For example, if the duration timer corresponding to the unicast does not operate for symbol n, if the configuration message of the valid BWP includes information about the CFR, and if the duration timer corresponding to the multicast in which the terminal device participates operates for symbol n, the terminal device does not transmit the semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH for cells or cell sets other than the cell related to the multicast (e.g., the cell related to the multicast such that symbol n is within the valid time of the multicast DRX).

[0588] Optionally, the third cell set is not associated with the second multicast service set.

[0589] The second set of multicast services includes at least one multicast service, and the at least one multicast service includes a sixth multicast service.

[0590] For example, the second multicast service set may include multicast / multicast services received by the terminal device, or multicast / multicast services in which the terminal device joins, or multicast / multicast services received by the terminal device and associated with the second BWP, or multicast / multicast services in which the terminal device joins and associated with the second BWP.

[0591] A multicast / multicast service received by a terminal device may include / be understood as a multicast / multicast service that will be received / has been received / is being received by the terminal device, and / or a configured multicast / multicast service related to the multicast / multicast service and obtained by the terminal device.

[0592] For example, the second set of multicast services may include multicast / multicast services received by the terminal device and for which multicast DRX is not configured, or multicast / multicast services joined by the terminal device and for which multicast DRX is not configured, or multicast / multicast services received by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or multicast / multicast services joined by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or multicast / multicast services associated with the second BWP and for which multicast DRX is not configured.

[0593] For example, the second multicast service set may include any one or more / all of the multicast / multicast services received by the terminal device and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services joined by the terminal device and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services received by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services joined by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services associated with the second BWP and for which multicast DRX is not configured.

[0594] For example, the ninth cell set is associated with the second multicast service set.

[0595] The ninth cell set includes at least one cell.

[0596] For example, the third cell set not being associated with the second multicast service set may be understood as the third cell set not being associated with the ninth cell set.

[0597] For example, the third cell set may 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 ninth cell set.

[0598] For example, a terminal device includes / has three cells: 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 1. Multicast DRX is configured for multicast 1, and no multicast DRX is configured for multicast 2. If the duration timer of the first DRX does not operate at the first time and the duration timer of the multicast DRX corresponding to multicast 1 does not operate at the first time, the terminal device does not transmit the first CSI at the first time for cell 3 and cell 2, the first DRX is unicast DRX, the third cell set is cell 3 and cell 2, and the ninth cell set is cell 1.

[0599] For example, if the duration timer corresponding to a unicast does not run for symbol n, if the configuration message of the valid BWP includes information about CFR, and if there is a multicast for which multicast DRX is not configured, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or does not transmit CSI on the PUCCH for cells or cell sets other than the cells related to the multicast for which multicast DRX is not configured.

[0600] For example, the third cell set may include cells / cell sets other than the cells / cell sets associated with the 14th multicast service set / third timer set and cells / cell sets associated with the second multicast service set, or cells / cell sets other than the seventh cell set and the ninth cell set.

[0601] For example, if the duration timer corresponding to a unicast does not operate for symbol n, if the configuration message of the valid BWP includes information about CFR, if the duration timer corresponding to a multicast in which the terminal device participates operates for symbol n, and if there is a multicast for which multicast DRX is not configured, the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit CSI on the PUCCH to cells or cell sets other than the cell related to the multicast (e.g., the cell related to the multicast for which multicast DRX is not configured) and the cell related to the multicast for which multicast DRX is not configured.

[0602] Optionally, the third set of cells is associated with the first timer or the first DRX.

[0603] For example, the association of a third cell set with a first timer or a first DRX may be understood as the same DRX parameters (e.g., parameters relating to the first timer or the first DRX) being used for the cells included in the third cell set, and the reception of control information for the cells included in the third cell set being controlled by the same DRX (e.g., the first timer or the first DRX).

[0604] Optionally, the third timer set / seventh cell set is associated with the first DRX / first cell set / first timer.

[0605] For example, the association of the seventh cell set with the first DRX may be understood as the same DRX parameters (e.g., parameters relating to the first DRX) being used for the cells included in the seventh cell set, and the reception of control information for the cells included in the seventh cell set being controlled by the same DRX (e.g., the first DRX).

[0606] Optionally, the first set of cells includes a third set of cells.

[0607] For example, the third set of cells is a subset of the first set of cells, or the third set of cells is equal to the first set of cells.

[0608] Optionally, the first set of cells includes a seventh set of cells.

[0609] 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.

[0610] Optionally, the first set of cells includes a third set of cells and a seventh set of cells.

[0611] For example, the third cell set and the seventh cell set are equal to the first cell set.

[0612] For example, there is no intersection between the third and seventh cell sets.

[0613] 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, or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins 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, or a multicast timer corresponding to a multicast / multicast service received by the terminal device and associated with the second BWP, or a multicast timer corresponding to a multicast / multicast service in which the terminal device joins and associated with the second BWP.

[0614] For example, the fourteenth 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, or a multicast / multicast service joined by the terminal device 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, or a multicast / multicast service received by the terminal device and associated with the second BWP, or a multicast / multicast service joined by the terminal device and associated with the second BWP.

[0615] For example, the third cell set may include a cell / cell set other than the cell / cell set associated with the 14th multicast service set / third timer set in the first cell set, or a cell / cell set other than the seventh cell set.

[0616] For example, a terminal device includes / has two DRX groups, where the first DRX group corresponds to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponds to three cells, cell 4, cell 5, and cell 6. The configuration message of the active BWP of cell 1 includes information about the CFR. The terminal device receives multicast 1 in cell 1. If the duration timer of the first DRX group does not operate at the first time and the duration timer of the multicast DRX corresponding to multicast 1 operates at the first time, the terminal device does not transmit the first CSI at the first time for cells other than cell 1 in the first cell set (i.e., cells 2 and 3), the first timer is the duration timer of the first DRX group, and the third timer set is the duration timer of the multicast DRX corresponding to multicast 1, the first cell set is cell 1, cell 2, and cell 3, and the third cell set is cell 2 and cell 3.

[0617] Optionally, the second multicast service set / ninth cell set is associated with the first DRX / first cell set.

[0618] 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, for which multicast DRX is not configured, or a multicast / multicast service joined by the terminal device and associated with the first cell set / first DRX, for which multicast DRX is not configured, or a multicast / multicast service associated with the first cell set / first DRX, for which multicast DRX is not configured, or a multicast / multicast service received by the terminal device and associated with the second BWP, for which multicast DRX is not configured, or a multicast / multicast service joined by the terminal device and associated with the second BWP, for which multicast DRX is not configured, or a multicast / multicast service associated with the second BWP, for which multicast DRX is not configured.

[0619] For example, the second multicast service set may include any one or more / all of the 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, or any one or more / all of the 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 of the multicast / multicast services associated with the first cell set / first DRX and for which multicast DRX is not configured, any one or more / all of the multicast / multicast services received by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services joined by the terminal device and associated with the second BWP and for which multicast DRX is not configured, or any one or more / all of the multicast / multicast services associated with the second BWP and for which multicast DRX is not configured.

[0620] For example, the association of the second multicast service set / ninth cell set with the first DRX / first cell set may be understood as the same DRX parameters (e.g., parameters relating to the first DRX) being used for the cells included in the ninth cell set, and the reception of control information for the cells included in the ninth cell set being controlled by the same DRX (e.g., the first DRX).

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

[0622] 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.

[0623] Optionally, the first set of cells includes a third set of cells and a ninth set of cells.

[0624] For example, the third cell set and the ninth cell set are equal to the first cell set.

[0625] For example, there is no intersection between the third and ninth cell sets.

[0626] For example, the third cell set may include a cell / cell set in the first cell set other than the cell / cell set associated with the second multicast service set, or a cell / cell set other than the ninth cell set.

[0627] For example, if the duration timer corresponding to one DRX group does not run for symbol n, if the configuration message of the active BWP related to the DRX group contains information about CFR, and if there are multicasts associated with the DRX group for which multicast DRX is not configured, the terminal device does not transmit CSI on the PUCCH for cells or cell sets other than the cells associated with the multicasts for which multicast DRX is not configured on / in the DRX group.

[0628] Optionally, the first set of cells includes a third set of cells, a seventh set of cells, and a ninth set of cells. Alternatively, optionally, the first set of cells includes a union of the seventh set of cells, the ninth set of cells, and the third set of cells.

[0629] For example, the third cell set, the seventh cell set, and the ninth cell set are equal to the first cell set.

[0630] For example, there is no intersection between the third and ninth cell sets.

[0631] For example, there is no intersection between the third cell set and the union of the seventh and ninth cell sets.

[0632] It should be noted that there may be an intersection between the seventh and ninth cell sets, or there may be no intersection between the seventh and ninth cell sets, and this is not a limitation in the present application.

[0633] It should be noted that the seventh set of cells may be the same as or different from the ninth set of cells, and this is not a limitation in this application.

[0634] For example, the third cell set may include, in the first cell set, cells / cell sets other than the cells / cell sets associated with the 14th multicast service set / third timer set and the cells / cell sets associated with the second multicast service set, or cells / cell sets other than the seventh cell set and the ninth cell set.

[0635] For example, if the duration timer corresponding to one DRX group does not run for symbol n, if the configuration message of the valid BWP associated with the DRX group contains information about CFR, if the duration timer corresponding to a multicast that the terminal device joins and that is associated with the DRX group runs for symbol n, and if there is a multicast associated with the DRX group for which multicast DRX is not configured, then the terminal device does not transmit semi-persistent CSI configured on the PUSCH and / or the terminal device does not transmit 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 validity time of the multicast DRX) and the cell associated with the multicast for which multicast DRX is not configured on / in the DRX group.

[0636] For example, the terminal device may transmit the first CSI or CSI at the first time for a cell set or cell other than the third cell set (e.g., the seventh cell set and / or the ninth cell set). For example, in a cell or cell set associated with the second 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 sixth multicast service, the terminal device may transmit the first CSI at the first time.

[0637] In some embodiments, it may be determined by the terminal device that the third timer set operates at the first time.

[0638] Optionally, operating the third timer set includes the terminal device determining that the third timer set is operating.

[0639] Optionally, the terminal device determining that the third timer set is running comprises: (1) The terminal device determines that a third timer set is activated based on or in consideration of one or both of an assignment (e.g., a received multicast-related assignment) and a multicast-related DRX Command MAC CE received at and / or before the tenth time; and / or (2) The method may include the terminal device determining, based on or in consideration of one or both of an assignment (e.g., a received multicast-related assignment) and a multicast-related DRX Command MAC CE received at and / or before the tenth time, that the third timer set operates, where the received assignment (e.g., the received multicast-related assignment) may be an assignment received in the seventh cell set or the first cell set, and / or a received assignment for the fourteenth 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 for the fourteenth multicast service set.

[0640] The tenth time period is determined based on the first time period and the ninth time period.

[0641] For example, the interval between the tenth time and the first time is a ninth time length, and the tenth time occurs before the first time.

[0642] It should be understood that the ninth period of time may be a parameter configured by the network device, or may be calculated according to a formula or algorithm, or may be specified in a protocol. This is not limited in the embodiments of the present application. For example, the ninth period of time is 4 ms.

[0643] Optionally, the preset condition includes condition 6, and the first CSI may be replaced with / may include / may be the seventh CSI.

[0644] The seventh 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:

[0645] Optionally, the preset condition includes condition 6, and "the terminal device does not transmit the first CSI at the first time" may be replaced with "may include / may be the terminal device does not transmit the seventh CSI at the first time."

[0646] Optionally, the terminal device not transmitting the seventh CSI at the first time includes: The terminal device does not transmit semi-persistent CSI; The terminal device does not transmit periodic CSI; The terminal device does not transmit CSI configured on the PUSCH; The terminal device does not transmit semi-persistent CSI configured on the PUSCH; The terminal device does not transmit configured CSI on the PUCCH; The terminal device does not transmit periodic CSI configured on the PUCCH; The terminal device does not transmit semi-persistent CSI configured on the PUCCH; The terminal device does not transmit CSI on the PUCCH; The terminal device does not transmit periodic CSI on the PUCCH; The terminal device does not transmit semi-persistent CSI on the PUCCH; The terminal device does not transmit CSI on the PUSCH, or The terminal device does not transmit semi-persistent CSI on the PUSCH. may include any one or more of:

[0647] For example, if condition 6 is met, the terminal device does not transmit the first CSI or the seventh CSI at the first time.

[0648] For example, if condition 6 is met, the terminal device does not transmit the first CSI or the seventh CSI at the first time for the third cell set.

[0649] Optionally, the preset conditions include condition 6, and the preset conditions may further include condition 7.

[0650] Optionally, the preset conditions may include condition 6, and the method in the present application may further include condition 7 being satisfied.

[0651] Optionally, the preset conditions include condition 6, and the preset conditions may further include condition 10.

[0652] Optionally, the preset conditions include condition 6, and the method in the present application may further include that condition 10 is satisfied.

[0653] For example, if CSI masking is configured for a terminal device, if a duration timer corresponding to unicast does not run for symbol n, if the configuration message for the valid BWP includes information about CFR, if a duration timer corresponding to multicast runs for symbol n, and if there is a multicast for which multicast DRX is not configured, the terminal device does not transmit CSI on the PUCCH to 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 validity time of the multicast DRX) and / or the cell associated with the multicast for which multicast DRX is not configured.

[0654] For example, if CSI masking is configured for a terminal device, if a duration timer corresponding to one DRX group does not run for symbol n, if a configuration message of an active BWP associated with the DRX group contains information about CFR, if a duration timer corresponding to a multicast associated with the DRX group runs for symbol n, and if there is a multicast associated with the DRX group for which multicast DRX is not configured, the terminal device does not transmit CSI on the PUCCH for cells or cell sets other than cells related to the multicast (e.g., cells related to the multicast for which symbol n is within the validity time of multicast DRX) and / or cells related to the multicast for which multicast DRX is not configured on / in the DRX group, or in cells or cell sets other than cells related to the multicast (e.g., cells related to the multicast for which symbol n is within the validity time of multicast DRX) and / or cells related to the multicast for which multicast DRX is not configured on / in the DRX group.

[0655] For example, if condition 6, condition 7, and condition 10 are met, the terminal device does not transmit the first CSI or the seventh CSI at the first time.

[0656] For example, if condition 6, condition 7, and condition 10 are satisfied, the terminal device does not transmit the first CSI or the seventh CSI at the first time for the third cell set.

[0657] Optionally, the pre-set condition may further include step 420 / condition 11.

[0658] Optionally, the method may further include step 420 .

[0659] 420: The terminal device obtains fifth information, where the fifth information indicates to the terminal device to transmit CSI based on multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer) or based on multicast.

[0660] Condition 11 may include the terminal device obtaining fifth information, where the fifth information indicates to the terminal device to transmit CSI based on multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer).

[0661] "Transmitting CSI based on multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer)" may be understood as any one or more of transmitting CSI based on unicast DRX (e.g., a unicast DRX / DRX group validity time and / or a unicast DRX / DRX group duration timer) and transmitting CSI based on multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer). The multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer) needs to be taken into consideration for transmitting the CSI. The unicast DRX (e.g., a unicast DRX / DRX group validity time and / or a unicast DRX / DRX group duration timer) and the multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer) need to be taken into consideration for transmitting the CSI.

[0662] Optionally, this step may be performed before step 410 .

[0663] The terminal device may acquire the fifth information according to the method steps in the above-described embodiments. For example, if the terminal device does not acquire the fifth information, the terminal device needs to transmit CSI based on multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer).

[0664] Optionally, the fifth information may be transmitted to the terminal device by the network device. Optionally, the granularity of the fifth information may be per terminal device or per multicast / multicast service (e.g., per G-RNTI and / or G-CS-RNTI). This is not limited in the present application. Optionally, among various terminal devices, some terminal devices may acquire the fifth information, and some terminal devices may not acquire the fifth information. This is not limited in the present application.

[0665] It may be understood that if condition 11 is not satisfied, the terminal device does not take into account one or more of whether multicast DRX is within the validity time, whether the multicast timer is running, whether multicast DRX is configured for multicast, and whether the configuration message of the BWP includes information about multicast CFR when deciding whether to transmit CSI.

[0666] For example, if condition 11 is not satisfied, condition 1, 2, or 3 may be replaced by the first time period not belonging to the first discontinuous reception (DRX) valid time. For example, if condition 11 is not satisfied, condition 4, 5, or 6 may be replaced by the first timer not running at the first time period.

[0667] Optionally, the method may further include step 430 .

[0668] 430: The terminal device transmits sixth information to the network device, where the sixth information indicates whether the terminal device can transmit CSI based on the multicast DRX (e.g., the multicast DRX validity time and / or the multicast DRX duration timer), and / or the terminal device transmits seventh information to the network device, where the seventh information indicates whether the terminal device wants to transmit CSI based on the multicast DRX (e.g., the multicast DRX validity time and / or the multicast DRX duration timer).

[0669] The sixth information is used by the terminal device to report to the network device an ability to transmit CSI based on multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer), and the seventh information is used by the terminal device to report to the network device whether the terminal device wants or does not want to transmit CSI based on multicast DRX (e.g., a multicast DRX validity time and / or a multicast DRX duration timer), which helps the network device select a mode.

[0670] Optionally, this step may be performed before step 410 .

[0671] It should be noted that the order of steps in this embodiment of the present application is not limited in the present application.

[0672] It should be noted that the order of determining different conditions in this embodiment of the present application is not limited in the present application.

[0673] It should be noted that in the method provided in this embodiment of the present application, it is limited in some cases that the terminal device does not transmit CSI (e.g., the first CSI). It can be understood that the terminal device may transmit CSI in cases other than the cases limited in this embodiment of the present application.

[0674] In this embodiment of the present application, the terminal device does not transmit the first CSI at the first time if a preset condition is met, which solves the problem of how the terminal device reports CSI in a scenario where the configuration message of the BWP may or may not include information about multicast CFR, avoids unnecessary CSI reporting, and thereby reduces the power consumption of the terminal device.

[0675] 4 is a diagram of another communication method according to an embodiment of the present application. As shown in FIG. 4, the method may include step 410.

[0676] 410: If a preset condition is met, the network device does not receive the first CSI at the first time.

[0677] It should be understood that step 410 refers to the relevant description in step 310. For example, in the technical measures in step 410, in some cases, the terminal device does not transmit CSI, and correspondingly, the network device does not receive CSI. Or, in some cases, the terminal device transmits CSI, and correspondingly, the network device receives CSI. Or, the terminal device acquires some information, for example, the first information, the second information, and the fifth information described above, and correspondingly, the network device transmits the information. Or, the terminal device does not acquire some information, for example, the third information and the fourth information described above, and correspondingly, the network device does not transmit the information. Or, the terminal device transmits some information, for example, the sixth information and the seventh information described above, and correspondingly, the network device receives the information. For brevity, the details will not be described again here.

[0678] It should be noted that "not receiving the first CSI" may include / be understood as any one or more of not decoding / not analyzing the CSI (e.g., the first CSI).

[0679] It should be noted that "the network device does not receive the first CSI at the first time" may include / be understood as any one or more of the network device not receiving CSI (e.g., the first CSI) on a PUCCH at the first time, the network device not decoding CSI (e.g., the first CSI) on a PUSCH at the first time, the network device determining not to receive the first CSI at the first time, and the network device determining that the terminal device does not transmit the first CSI at the first time.

[0680] In this embodiment of the present application, a network device does not receive a first CSI at a first time if a preset condition is met. This solves the problem of how a network device receives CSI in a scenario where a BWP configuration message may or may not include information about multicast CFR. A feasible method is provided. When receiving CSI, the network device not only considers unicast DRX and / or multicast DRX (or multicast), but also considers whether the BWP configuration message includes information about multicast CFR. Therefore, when receiving CSI or decoding / analyzing data / CSI, the network device can correctly determine whether CSI is present. This helps improve decoding accuracy and communication quality (e.g., improve reliability). In this way, the network device does not need to constantly receive CSI, thereby saving energy for the network device. In addition, the network device can use PUCCH resources where CSI is not transmitted, thereby improving resource utilization.

[0681] It should be noted that in the embodiment of FIG. 3 and / or the embodiment of FIG. 4, the first CSI may be replaced with a first SRS (Sounding Reference Signal), and the CSI may be replaced with an SRS. This may be used as a separate embodiment or two embodiments. The separate embodiment or two embodiments may be combined with the embodiment of FIG. 3 and / or the embodiment of FIG. 4, or may be used as independent embodiments.

[0682] Optionally, the first SRS may include a periodic SRS and / or a semi-persistent SRS.

[0683] For example, the terminal device does not transmit the first CSI and / or the first SRS at the first time if a preset condition is met.

[0684] Problem 2: In the prior art, when a terminal device switches to BWP, even if the configuration message of the BWP does not include information about multicast CFR, the timer of the multicast DRX of the terminal device continues to run, and the multicast DRX continues to be within the valid time. Therefore, the terminal device also transmits CSI and / or SRS. However, if the configuration message of the valid BWP of the terminal device does not include information about multicast CFR, the terminal device cannot (or may not) receive the multicast service / data, or the terminal device does not receive the multicast service / data. It can be understood that transmitting CSI and / or SRS in this case is meaningless, and the power consumption of the terminal device may increase.

[0685] The following describes another communication method provided in an embodiment of the present application with reference to FIG.

[0686] 510: When the terminal device is switched to the third BWP, the terminal device stops the timer corresponding to the multicast DRX.

[0687] The configuration message of the third BWP does not contain information about the CFR.

[0688] Optionally, "switching to a third BWP" may include switching from a fifth BWP to the third BWP.

[0689] For example, the configuration message of the fifth BWP contains information about the CFR.

[0690] For example, "when the terminal device is switched to the third BWP" may include after the terminal device is switched to the third BWP.

[0691] For example, the third BWP may be understood as the effective BWP.

[0692] For example, "switching to a third BWP" may include enabling the third BWP.

[0693] The timers corresponding to multicast DRX include one or more of a fourth timer, a fifth timer, a sixth timer, and a seventh timer.

[0694] The fourth timer is a duration timer corresponding to multicast DRX (eg, drx-onDurationTimerPTM).

[0695] The fifth timer is an inactivity timer corresponding to multicast DRX (eg, drx-InactivityTimerPTM).

[0696] The sixth timer is a retransmission timer corresponding to multicast DRX (eg, drx-RetransmissionTimerDL-PTM).

[0697] The seventh timer is an RTT timer corresponding to multicast DRX (for example, drx-HARQ-RTT-TimerDL-PTM).

[0698] For example, a duration timer corresponding to a duration timer / multicast DRX indicates the length of time that a terminal device waits to receive control information (eg, DCI) after being woken up.

[0699] For example, an inactivity timer corresponding to multicast DRX indicates a period after newly transmitted data or control information for scheduling a new transmission.

[0700] For example, a retransmission timer corresponding to a multicast DRX indicates the length of time for a terminal device to receive a retransmission (eg, DCI, data, and resources) corresponding to the multicast.

[0701] Optionally, the timers corresponding to multicast DRX include timers corresponding to all multicast DRX.

[0702] Optionally, the timer corresponding to multicast DRX includes a timer corresponding to multicast DRX associated with a third BWP.

[0703] Optionally, the timers corresponding to multicast DRX include timers corresponding to all multicast DRX and associated with a third BWP.

[0704] In this embodiment of the present application, when the terminal device switches to the third BWP and the configuration message of the third BWP does not include information about CFR, the terminal device stops the timer corresponding to multicast DRX, which avoids unnecessary CSI reporting and thereby reduces the power consumption of the terminal device.

[0705] 6 is a diagram of another communication method according to an embodiment of the present application. As shown in FIG. 6, the method may include step 610.

[0706] 610: When the terminal device is switched to the third BWP, the network device stops the timer corresponding to the multicast DRX.

[0707] It should be understood that for step 610, reference is made to the related description in step 510. For example, in the technical measures in step 610, in some cases, the terminal device stops a timer corresponding to multicast DRX, and correspondingly, the network device stops a timer corresponding to multicast DRX. For the sake of brevity, the details will not be described again here.

[0708] In this embodiment of the present application, when the terminal device switches to the third BWP and the configuration message of the third BWP does not include CFR configuration information, the network device stops the timer corresponding to multicast DRX. In this way, the network device does not need to constantly receive CSI, thereby saving energy for the network device. In addition, the network device can use PUCCH resources on which CSI is not transmitted, thereby improving resource utilization.

[0709] Question 3: In the prior art, when multicast DRX is configured for a terminal device, a multicast DRX timer (e.g., drx-onDurationTimerPTM) of the terminal device is started, and multicast DRX is within a valid time. Therefore, the terminal device transmits CSI and / or SRS. However, if the configuration message of a valid BWP of the terminal device does not include information about multicast CFR, the terminal device cannot (or may not) receive multicast services / data, or the terminal device does not receive multicast services / data. It can be understood that transmitting CSI and / or SRS in this case is meaningless and may increase the power consumption of the terminal device.

[0710] Hereinafter, with reference to FIG. 7, another communication method provided in an embodiment of the present application will be described.

[0711] 710: If the configuration message of the fourth BWP includes information about CFR and multicast DRX is configured for the terminal device, the terminal device performs multicast DRX.

[0712] For example, the fourth BWP is a valid BWP for the terminal device.

[0713] Configuring multicast DRX for a terminal device may include configuring multicast DRX for the terminal device for any one or more of the 15th multicast service, the 6th G-RNTI, and the 6th G-CS-RNTI, or configuring multicast DRX for any one or more of the 15th multicast service, the 6th G-RNTI, and the 6th G-CS-RNTI.

[0714] Optionally, the terminal device performing multicast DRX may include the terminal device starting an eighth timer and / or the terminal device monitoring a PDCCH during the effective time of the multicast DRX.

[0715] The eighth timer is a duration timer corresponding to multicast DRX (eg, drx-onDurationTimerPTM).

[0716] Optionally, the terminal device starting the eighth timer may include the terminal device starting the eighth timer drx-SlotOffsetPTM after the first subframe.

[0717] The first subframe is determined according to the formula: [(SFN×10)+subframe number] modulo (drx-LongCyclePTM)=drx-StartOffsetPTM.

[0718] For example, SFN is the system frame number. For example, subframe number is the first subframe. For example, drx-LongCyclePTM is the multicast DRX cycle. For example, drx-StartOffsetPTM is the subframe before the start of multicast DRX. For example, drx-StartOffsetPTM is the offset of multicast DRX.

[0719] For example, the drx-LongCyclePTM, drx-StartOffsetPTM, and drx-SlotOffsetPTM are configured by the network device for the terminal device and are used to determine the start opportunity of the drx-onDurationTimerPTM.

[0720] For example, drx-LongCyclePTM indicates the time length of a DRX cycle. For example, drx-StartOffsetPTM indicates the subframe where the DRX cycle starts. For example, drx-StartOffsetPTM is used when calculating the frame number and subframe number of the starting opportunity for drx-onDurationTimerPTM. It can be understood that drx-StartOffsetPTM is used to determine the subframe within a frame where drx-onDurationTimerPTM starts.

[0721] For example, drx-SlotOffsetPTM indicates a delay before the start of drx-onDurationTimerPTM and is an offset in a subframe used when the start opportunity of drx-onDurationTimerPTM is calculated. For example, the value range of drx-SlotOffsetPTM is 0 ms to (31 / 32) ms, with an accuracy of (1 / 32) ms. It can be understood that after the terminal device determines the subframe in which drx-onDurationTimerPTM in a frame starts based on drx-SlotOffsetPTM, the terminal device determines the specific (1 / 32) ms in which drx-onDurationTimerPTM in the subframe (i.e., the subframe determined based on drx-StartOffset) starts based on drx-SlotOffsetPTM.

[0722] Optionally, the multicast DRX is associated with any one or more of the 15th multicast service, the 6th G-RNTI, and the 6th G-CS-RNTI.

[0723] The cell corresponding to the fourth BWP or the fourth BWP is associated with any one or more of the multicast DRX, the 15th multicast service, the sixth G-RNTI, and the sixth G-CS-RNTI.

[0724] In this embodiment of the present application, if the configuration message of the fourth BWP includes information about CFR and multicast DRX is configured for the terminal device, the terminal device performs multicast DRX, which avoids unnecessary CSI reporting and thereby reduces the power consumption of the terminal device.

[0725] 8 is a diagram of another communication method according to an embodiment of the present application. As shown in FIG. 8, the method may include step 810.

[0726] 810: If the configuration message of the fourth BWP includes the configuration information of the CFR and multicast DRX is configured for the terminal device, the network device performs multicast DRX.

[0727] It should be understood that for step 810, reference may be made to the relevant description in step 710. For example, in the technical measures in step 810, in some cases, the terminal device activates a timer corresponding to multicast DRX, and correspondingly, the network device activates a timer corresponding to multicast DRX. For the sake of brevity, the details will not be described again here.

[0728] In this embodiment of the present application, when a network device and a terminal device operate on the fourth BWP, if the configuration message of the fourth BWP includes information about CFR and multicast DRX is configured for the terminal device, the network device performs multicast DRX, and performs multicast DRX when the above-mentioned conditions are met. In this way, the network device does not need to constantly receive CSI, thereby saving energy for the network device. In addition, the network device can use PUCCH resources on which CSI is not transmitted, thereby improving resource utilization.
