Description

Technical Field

[0001] This application claims the priority of Chinese Patent Application No. 202210957937.2, filed with the China National Intellectual Property Administration on August 10, 2022, under the title of "COMMUNICATION METHOD AND COMMUNICATION APPARATUS", the entire content of which is incorporated herein by reference.

[0002] Embodiments of this application relate to the field of communications, and more specifically, to communication methods and communication apparatuses.

Background Art

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

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

[0005] In the prior art, when the multicast DRX is within the effective time or the multicast DRX is not configured for multicast, the terminal device may report unnecessary CSI.

Alternatively, a network device could be a network device in a future advanced public land mobile network (PLMN), for example.

[0103] To better understand the communication method disclosed in the embodiments of this application, relevant concepts in the embodiments of this application are briefly explained.

[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 effectively utilize mobile communication network resources and provides a point-to-multipoint service in which a data source transmits data to multiple users on a mobile communication network, thereby implementing network resource sharing and improving resource utilization, particularly air interface resources. NR MBS supports multicast and broadcast.

[0105] 2. Multicast and Unicast Multicast may include any one or more of the following: multimedia broadcast multicast service (MBMS) or broadcast in 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] Groupcast services may include / may be replaced by any one or more of the following: broadcast services, multicast services, MBS services, MBS broadcast services, MBS multicast services, V2X multicast services, and V2X broadcast services.

[0107] Data that corresponds to multicast services can be called multicast data.

[0108] Unicast can include either or both of the unicast and unicast in V2X. Optionally, unicast can be understood as unicast transmission.

[0109] Multicast services can also be understood as multicast sessions or MBS sessions.

[0110] In the embodiments of this application, "groupcast" can be replaced with other nouns such as "multicast." Correspondingly, the groupcast service can be replaced with a multicast service.

[0111] Multicast allows the same service and / or the same content data to be delivered simultaneously to one group / multiple terminal devices.

[0112] For example, multicast may be directed to a specific group of terminal devices, and these terminal devices may need to perform a "group joining process."

[0113] In contrast, unicast can be understood as providing the same service and / or the same content data to a single terminal device simultaneously. Unicast can be understood as follows: If one piece of data needs to be sent to multiple devices, the data must be sent to each device separately.

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

[0115] The following is a brief explanation of DRX with reference to Figure 2.

[0116] Figure 2 shows a DRX cycle according to an embodiment of this application. As shown in Figure 2, a DRX cycle may include a duration (e.g., on-duration) or wake-up time (e.g., on-duration) and a sleep time (e.g., opportunity for DRX). The duration is the length of time the terminal device waits after being woken up to receive the PDCCH. During this duration, the terminal device monitors the PDCCH. If the terminal device is able to successfully decode the PDCCH, it may remain awake or extend its validity period. The sleep time is the sleep time of the terminal device. During this time, the terminal device does not need to monitor the PDCCH to reduce power consumption. It can be understood that a longer sleep time for the terminal device indicates lower power consumption, but correspondingly, it may result in increased delays in the terminal device's service transmission.

[0117] The DRX functionality of a terminal device may be configured by a network device. Even when a network device configures the DRX functionality for a terminal device, it should be noted that the terminal device may still 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 must then continuously monitor the PDCCH regardless of its DRX status.

[0118] 3.1 Unicast DRX When a DRX group is not configured (or in R15), the 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 executes one set of DRX.

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

[0121] When a DRX group is not configured, the DRX validity period is: drx-onDuration Timer operating time, drx-InactivityTimer operating time, Operating time of drx-RetransmissionTimerDL, Operating time of drx-RetransmissionTimerUL, Operating time of drx-RetransmissionTimerSL, The time spent waiting for a scheduling request (SR) to be sent over the physical uplink control channel (PUCCH) and for the SR to be processed, and The time at which a PDCCH, scrambled by C-RNTI and indicating that no new transmissions are received after a random access response (RAR), can be successfully received in a non-contention-based random access process (i.e., after a successful non-contention-based random access (RA)). It may include any one or more of the following.

[0122] Network devices control DRX operation by configuring any one or more of the following parameters using Radio Resource Control (RRC) messages. drx-onDurationTimer: The duration at the beginning of a DRX cycle. The position at which drx-onDurationTimer is started or restarted can be calculated based on the parameters configured by the base station and the formula specified in the protocol. drx-InactivityTimer: The period following a PDCCH occasion that indicates a new uplink or downlink transmission. For example, when a terminal device receives a PDCCH (e.g., a PDCCH scrambled by C-RNTI or CS-RNTI) indicating that there is a new uplink or downlink transmission (i.e., a new transmission scheduling), the drx-InactivityTimer is started or restarted. drx-RetransmissionTimerDL: The maximum time until a downlink (DL) retransmission is received. For example, if drx-HARQ-RTT-TimerUL expires and data decoding is unsuccessful, drx-RetransmissionTimerDL is started or restarted. drx-RetransmissionTimerUL: The maximum time until a grant for uplink (UL) retransmission is received. For example, in the first symbol after drx-HARQ-RTT-TimerUL has expired, drx-RetransmissionTimerUL is started or restarted for the corresponding HARQ process. Drx-HARQ-RTT-TimerDL: The shortest time until a DL allocation for HARQ retransmission is expected by the MAC entity, or the shortest time 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) to indicate that there is a downlink transmission, or a terminal device receives data in a configured downlink allocation (e.g., an SPS resource associated with unicast), and drx-HARQ-RTT-TimerDL is started or restarted after the feedback, with RTT representing Round Trip Time. drx-HARQ-RTT-TimerUL: The shortest time duration until the UL HARQ retransmission grant is expected by the MAC entity, or the shortest time duration until the UL HARQ retransmission grant is expected to be received by the MAC entity. For example, a terminal device sends a MAC protocol data unit (PDU) on a configured uplink grant (e.g., an SPS resource associated with 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. drx-HARQ-RTT-TimerSL: The shortest time duration until the expected time of an SL retransmission grant or the shortest time duration until the expected time of an SL retransmission grant being received.

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

[0124] The following is a brief explanation of the DRX group.

[0125] DRX Groups: Within a single 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 secondary DRX groups 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 executes one set of DRX, meaning that in one MAC entity, there may be two DRX groups, and two sets of DRX will be executed.

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

[0129] The following is a brief explanation of DCP.

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

[0131] For example, when the DCP function is configured for a terminal device, the terminal device may decide whether or not to start the drx-onDurationTimer in one of the following ways:

[0132] Method 1: If a network device configures ps-wakeup for a terminal device and the terminal device does not detect DCI scrambled by PS-RNTI, the terminal device may start 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 that is scrambled by PS-RNTI, and the DCI indicates that the terminal device should be woken, the terminal device starts drx-onDurationTimer.

[0134] 3.2. 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 specific associations or interactions between unicast DRX and multicast DRX. For example, when receiving DCI scrambled by a G-RNTI, a terminal device may also start or restart the unicast DRX's drx-HARQ-RTT-TimerDL and / or stop the unicast DRX's drx-RetransmissionTimerDL.

[0135] For a single multicast or for a single G-RNTI or G-CS-RNTI, the multicast DRX active time may include any one or more of the following: 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] Network devices control multicast DRX operation by configuring any one or more of the following parameters using RRC messages. drx-onDurationTimerPTM: The duration at the beginning of a DRX cycle. The location where drx-onDurationTimerPTM is started or restarted is calculated based on the parameters configured by the base station and the formula specified in the protocol. drx-InactivityTimerPTM: The period following a PDCCH opportunity that indicates a new DL transmit scheduling. For example, a terminal device receives a PDCCH (e.g., a PDCCH scrambled by G-RNTI or G-CS-RNTI) indicating that there is a new downlink transmit (i.e., a new transmit scheduling), and the drx-InactivityTimerPTM is started or restarted. drx-RetransmissionTimerDL-PTM: The maximum time until a DL retransmission is received. For example, if drx-HARQ-RTT-TimerDL-PTM expires and data decoding is unsuccessful, drx-RetransmissionTimerDL-PTM is started or restarted. drx-HARQ-RTT-TimerDL-PTM: The shortest time duration until a DL retransmission is expected, or the shortest time duration until a DL retransmission is expected to be received. For example, a terminal device receives a PDCCH (e.g., a PDCCH scrambled by G-RNTI or G-CS-RNTI) to indicate that there is a downlink transmission, or a terminal device receives data in a downlink allocation in a multicast configuration, causing drx-HARQ-RTT-TimerDL-PTM to be started or restarted.

[0138] Note that any one or more of the following are for each HARQ process (per HARQ process): 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. For example, a terminal device maintains different drx-HARQ-RTT-TimerDLs for different HARQ processes. For example, a terminal device maintains different drx-RetransmissionTimeULs for different HARQ processes. For example, a terminal device maintains different drx-HARQ-RTT-TimerDL-PTMs for different HARQ processes. For example, a terminal device maintains different drx-RetransmissionTimerDL-PTMs for different HARQ processes.

[0139] Note that either or both of the drx-HARQ-RTT-TimerDL-PTM and drx-RetransmissionTimerDL-PTM are specific to each G-RNTI and / or G-CS-RNTI (per G-RNTI and / or G-CS-RNTI) or to 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 for different multicast / multicast services.

[0140] For details regarding DRX, please refer to 3GPP TS 38.321: "NR; Medium Access Control (MAC); Protocol specification". Further details will not be explained here.

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

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

[0143] For example, CSI configuration information can be configured by a network device 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 a method for terminal devices to transmit CSI and SRS to network devices in R15, R16, and R17.

[0146] In R15 (or when DCP monitoring is not configured and no DRX group is configured), the methods by which a terminal device transmits CSI and SRS over unicast DRX include one or both of the following: (1) If symbol n is not within the DRX validity period, the terminal device will not transmit a semi-persistent CSI consisting of PUSCH, the terminal device will not transmit a CSI on PUCCH, or the terminal device will not transmit a periodic SRS or a semi-persistent SRS.

(1.2) If ps-TransmitPeriodicL1-RSRP is not configured for the terminal device and ps-TransmitPeriodicL1-RSRP being true indicates that the terminal device should report a periodic CSI which is L1-RSRP in this case, the terminal device will not transmit a periodic CSI which is L1-RSRP on PUCCH, and (1.3) If ps-TransmitOtherPeriodicCSI is not configured to be true for the terminal device, and ps-TransmitOtherPeriodicCSI being true indicates that the terminal device needs to report a periodic CSI that is not L1-RSRP in this case, the terminal device will not transmit a periodic CSI that is not L1-RSRP on PUCCH. Perform any one or more of the following. (2) If DCP monitoring is not configured for the terminal device, or symbol n is not within the duration of the drx-onDurationTimer, or if the drx-onDurationTimer is started in the current DRX cycle and symbol n is not within the DRX validity period, the terminal device will not transmit a semi-persistent CSI configured on PUSCH, the terminal device will not transmit a CSI on PUSCH, or the terminal device will not transmit a periodic SRS or a semi-persistent SRS.

[0148] In R16 (or when a DRX group is configured), alternative methods for a terminal device to transmit CSI and SRS over unicast DRX include one or both of the following: (1) If symbol n is not present within the validity period of a DRX group, in that DRX group, the terminal device will not transmit a semi-persistent CSI consisting of a PUSCH, the terminal device will not transmit a CSI on a PUCCH in the DRX group, or the terminal device will not transmit a periodic SRS or semi-persistent SRS in the DRX group. (2) If CSI-masking is configured for a terminal device and drx-onDurationTimer for one DRX group does not operate for symbol n, the terminal device will not send a CSI on PUCCH in the DRX group.

[0149] In R17 (or when multicast is present), the methods by which a terminal device transmits CSI and SRS include any one or more of the following: (1) If DCP monitoring is configured for the terminal device, and symbol n is within the duration of the drx-onDurationTimer, and the drx-onDurationTimer is not started in the current DRX cycle, and symbol n is not within the validity period of the unicast DRX, and the terminal device is not configured to send CSI and / or SRS based on multicast DRX, the terminal device shall perform any one or more of the following: (1.1) The terminal device does not transmit a semi-persistent CSI configured on PUSCH, and the terminal device does not transmit a periodic SRS or a semi-persistent SRS.

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

[0152] For example, BWP can be understood as a subset of cell bandwidth. For example, BWP can be understood as part of cell bandwidth. For example, cell bandwidth includes BWP. For example, BWP may be equivalent to cell bandwidth.

[0153] For example, for a single cell, a terminal device may acquire the configuration of one or more BWPs, and the terminal device may perform BWP switching. However, at a given time, there is only one active BWP. On that active BWP, the terminal device may perform transmission or reception. For example, for an active BWP, the terminal device may perform any one or more of the following: transmit on UL-SCH, transmit on RACH, monitor PDCCH, transmit PUCCH, report CSI, transmit SRS, receive DL-SCH, transmit PSBCH, transmit PSCCH, transmit SL-SCH, transmit PSFCH, receive PSFCH, receive PSBCH, receive PSCCH, and receive SL-SCH.

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

[0155] For example, for a single 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 a multicast CFR. The terminal device may receive multicast services / data on the multicast CFR. For example, if the configuration message of a terminal device's active BWP includes information about a multicast CFR, the terminal device may receive multicast services / data on the BWP or multicast CFR, or if the configuration message of a terminal device's active BWP does not include information about a multicast CFR, the terminal device may not receive multicast services / data on the BWP.

[0156] While BWP or CFR are used in this description, please note that the names BWP or CFR are not limited to BWP or CFR, and other names may be used.

[0157] Problem 1: In conventional technology, in the following two scenarios, the terminal device sends a CSI and / or SRS even if the configuration message of the terminal device's active BWP does not contain information about multicast CFRs. However, if the configuration message of the terminal device's active BWP does not contain information about multicast CFRs, the terminal device may not receive (or may not receive) multicast services / data, or the terminal device may not receive multicast services / data. It can be understood that sending a CSI and / or SRS in this case is meaningless and may increase the terminal device's power consumption. For example, in this scenario, the network device may not perform the relevant multicast scheduling, so the terminal device does not need to send a CSI and / or SRS. Alternatively, the network device needs to perform the relevant multicast scheduling, but the terminal device does not receive multicast services / data, so the network device does not need to consider the terminal device's CSI and / or SRS when performing multicast scheduling, and therefore the terminal device does not need to send a CSI and / or SRS.

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

[0159] Scenario 2: When the multicast DRX of the multicast in which the terminal device participates is active, or when the drx-onDurationTimerPTM of the multicast in which the terminal device participates is active.

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

[0161] Note that in the embodiments of this application, the terminal device is used as an illustrative example. Alternatively, the terminal device may be replaced by the MAC entity of the terminal device, another entity of the terminal device, or another device, but this is not limited to this application.

[0162] In the embodiments of this application, "do not transmit" may be understood as "do not report".

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

[0164] In the embodiments of this application, “not belonging to” is understood as “not in” or “not existing.”

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

[0166] In the embodiments of this application, “associated” may be understood as “corresponding.”

[0167] In the embodiments of this application, “not included” may be understood as “not present.”

[0168] In the embodiments of this application, the bandwidth portion may be understood as / replaced by a bandwidth segment.

[0174] In the optional category, "meeting pre-set conditions" may include the terminal device determining when pre-set conditions are met.

[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 to the embodiments of this 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.

It may include any one or more of the following.

[0181] It should be noted that under different conditions, the “first CSI” may be different or the same, and / or the condition “the terminal device does not transmit the first CSI at a first time” may be different or the same. This is not limited to the present application.

[0182] Condition 1: The first time does not fall within the validity period of the first DRX, and the configuration message of the first BWP does not contain information about the 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 the monitoring of control information that is not specific to the terminal device. This is not limited to the present application.

[0185] For example, the first DRX may be used to control the 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 (PUCCH-RNTI, TPC-PUCCH-RNTI), Transmit Power Control-Physical Uplink Sharing Channel RNTI (PUSCH-RNTI, TPC-PUSCH-RNTI), Transmit Power Control-Sounding Reference Signal RNTI (TPC-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 could be a unicast DRX or a group of DRXs (for example, a single group of DRXs).

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

[0188] For example, a retransmission timer for unicast may include any one or more of the following: a downlink retransmission timer (e.g., drx-RetransmissionTimerDL), an uplink retransmission timer (e.g., drx-RetransmissionTimerUL), or a sidelink retransmission timer (e.g., drx-RetransmissionTimerSL).

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

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

[0191] For example, a retransmission timer / unicast-compatible retransmission timer indicates the length of time a terminal device will receive a retransmission (e.g., DCI, data, and resources).

[0192] For example, a downlink retransmission timer / unicast-compatible downlink retransmission timer indicates the length of time a terminal device will receive downlink retransmissions (e.g., DCI, data, and resources).

[0193] For example, an uplink retransmission timer corresponding to an uplink retransmission timer / unicast indicates the length of time a terminal device will receive an uplink retransmission (e.g., DCI, data, and resources).

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

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

[0196] It should be noted that the validity period of the first DRX may further include other periods, which are not limited to this application. For example, see 3GPP TS 38.321: "NR; Medium Access Control (MAC); Protocol specification" for the content of the validity period of the first DRX.

[0197] Optionally, this application may further include a terminal device receiving a configuration message for 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 broadcast message / system information (e.g., SIB1). This is not limited to this application.

[0198] The first BWP includes the active BWP.

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

[0200] For example, an active BWP may include a working BWP, an active BWP on a terminal device, or all working BWPs on a terminal device.

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

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

[0203] For example, "The configuration message of the first BWP does not contain information about the CFR" means that information about the CFR is not present in the configuration message of the first BWP.

[0204] Optionally, the first BWP may include all active BWPs. Optionally, the first BWP may include active BWPs for cells / cell sets corresponding to multicasts that the terminal device participates in or receives. Optionally, the first BWP may include active BWPs for cells / cell sets corresponding to all multicasts that the terminal device participates in.

[0205] For example, a terminal device may support or operate across multiple cells, and the first BWP may include an active BWP that supports multiple cells.

[0206] For example, if symbol n is not within the validity period of a unicast DRX and each valid BWP configuration message does not contain information about the CFR, the terminal device will not send a semi-persistent CSI configured on PUSCH, and / or the terminal device will not send a CSI on PUSCH.

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

[0208] The first set of cells contains at least one cell, and the first set of cells is associated with the first DRX.

[0209] For example, the first DRX is a DRX group (for example, the first DRX group). The first set of cells is the set of cells corresponding to the DRX group (for example, the first DRX group).

[0210] Optionally, the first BWP is associated with either the first DRX or the first set of cells.

[0211] In this application, "a BWP (e.g., a first BWP or a second BWP) is associated with a first DRX or a set of cells (e.g., a first set of cells)" can be understood as "a cell / set of cells corresponding to a BWP (e.g., a first BWP or a second BWP) is associated with a first DRX or a set of cells (e.g., a first set of cells)."

[0212] Optionally, the first BWP may include all active BWPs associated with the first DRX or the first cell set. Optionally, the first BWP may include active BWPs for multicast-compatible cells / cell sets that terminal devices join or receive and that are associated with the first DRX or the first cell set. Optionally, the first BWP may include active BWPs for all multicast-compatible cells / cell sets that terminal devices join or receive and that are associated with the first DRX or the first cell set.

[0213] For example, the first cell set contains multiple cells, and the first BWP contains all valid BWPs corresponding to those multiple cells.

[0214] For example, if symbol n is not within the validity period of a DRX group, and each valid BWP configuration message associated with that DRX group does not contain information about the CFR, then the terminal device will not send a semi-persistent CSI configured on the PUSCH, and / or the terminal device will not send a CSI on the PUSCH, to or within that DRX group.

[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 be understood to include / include either the terminal device not transmitting a CSI (e.g., the first CSI) within the first cell set at the first time, or the terminal device not transmitting a CSI for the first cell set (e.g., the first CSI) at the first time.

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

[0217] Regarding the statement "the terminal device does not transmit a CSI for the first cell set (e.g., the first CSI) at the first time," please note that this application does not limit whether the terminal device transmits a CSI for another cell or cell set within the first cell set.

[0218] In the statement "The terminal device does not transmit the first CSI at the first time for the first set of cells," note that "the first set of cells" may be replaced with "may include / may be understood as including the first DRX." For example, "for the first set of cells" may be understood as including / may be including "for the first DRX." For example, "in the first set of cells" may be understood as including / may be including "in the first DRX." For example, "for the first set of cells" may be understood as including / may be including "for the first DRX."

[0219] In some embodiments, whether the first time falls within the validity period of the first DRX can be determined by the terminal device.

[0220] Optionally, the fact that the first time does not belong to the validity period of the first DRX includes the terminal device determining that the first time does not belong to the validity period of the first DRX.

[0221] The terminal device may optionally decide that the first time period does not belong to the validity period of the first DRX. (1) A terminal device may determine that the first time does not belong to the valid time of the first DRX based on or in consideration of any one or more of grants, assignments, DRX Command MAC CEs, and Long DRX Command MAC CEs received in and / or before the second time, and / or based on or in consideration of scheduling requests sent in and / or before the second time, and / or (2) A terminal device may determine that a first time does not belong to the valid time of a first DRX, based on or in consideration of any one or more of grants, assignments, DRX Command MAC CEs, and Long DRX Command MAC CEs received in a second time and / or before the second time, and / or based on or in consideration of scheduling requests sent in a second time and / or before the second time, wherein the received grants and assignments may be grants and assignments received in a first cell set.

[0222] Optionally, grants include unicast-related grants.

[0223] Optional, the assignment includes unicast-related assignments.

[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 includes a unicast-related scheduling request.

[0227] The second time is determined based on the first time and the first time duration.

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

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

[0230] Optionally, the preset condition includes condition 1, and the first CSI may be / may include / may be replaced by 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 / may include / may be replaced by the terminal device not transmitting the second CSI at the first time.

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

[0233] Optionally, the pre-set conditions include Condition 1, and the method in the present application may further include that Condition 7 is satisfied.

[0234] Optionally, the pre-set conditions include Condition 1, and the first CSI may be / may include / may be replaced by the third CSI.

[0235] Optionally, the pre-set conditions include Condition 1, and "the terminal device does not transmit the first CSI at the first time" may be / may include / may be replaced by the fact that the terminal device does not transmit the third CSI at the first time.

[0236] Optionally, the pre-set conditions include Condition 1, and the pre-set conditions may further include Condition 8.

[0237] Optionally, the pre-set conditions include Condition 1, and the method in the present application may further include that Condition 8 is satisfied.

[0238] Optionally, the pre-set conditions include Condition 1, and the pre-set conditions may further include Condition 9.

[0239] Optionally, the pre-set conditions include Condition 1, and the method in the present application may further include that Condition 9 is satisfied.

[0240] For example, when 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.

[0241] For example, when 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 DCP is not configured for a terminal device, or symbol n is not within the duration of a unicast-compatible duration timer, or a unicast-compatible duration timer is not started or restarted, and symbol n is not within the validity period of a DRX group, and the configuration messages for each valid BWP associated with that DRX group do not contain information about the CFR, then to or within that DRX group, the terminal device will not send a semi-persistent CSI configured on PUSCH, and / or the terminal device will not send a CSI on PUSCH.

[0243] For example, if DCP is configured for a terminal device, and symbol n is within the duration of the unicast-corresponding duration timer, and the unicast-corresponding duration timer is not started or restarted, if symbol n is not within the validity period of the unicast DRX, and each valid BWP configuration message does not contain information about the CFR, then the terminal device will The terminal device does not transmit a semi-persistent CSI configured on PUSCH. If the terminal device is not configured to report periodic CSIs or CSIs that are L1-RSRP, the terminal device will not send periodic CSIs that are L1-RSRP on PUCCH, or If the terminal device is not configured to report periodic CSIs or CSIs that are not L1-RSRP, the terminal device will not send periodic CSIs that are not L1-RSRP on PUCCH. Any one or more of these may be implemented.

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

[0245] The second DRX set may include at least one multicast DRX, and 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 relating to the third multicast service.

[0246] For example, the second DRX set may include DRXs corresponding to multicast / multicast services received by the terminal device, or DRXs corresponding to multicast / multicast services in which the terminal device participates, or DRXs corresponding to multicast / multicast services received by the terminal device and associated with the second BWP, or DRXs corresponding to multicast / multicast services in which the terminal device participates and is associated with the second BWP.

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

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

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

[0250] For example, the tenth multicast service set may include a multicast / multicast service received by a 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 is associated with the second BWP.

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

[0252] For example, the third multicast service may be understood as a multicast service associated with a first G-RNTI and / or a first G-CS-RNTI, or a multicast associated with a first G-RNTI and / or a first G-CS-RNTI.

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

[0254] Note that the first multicast DRX may also be used to control the monitoring of other control information. This is not limited in this application.

[0255] For example, the validity period of a multicast DRX may include any one or more of the following: the operating time of a duration timer (e.g., drx-onDurationTimerPTM) corresponding to multicast (e.g., G-RNTI and / or G-CS-RNTI); the operating time of an inactivity timer (e.g., drx-InactivityTimerPTM) corresponding to multicast (e.g., G-RNTI and / or G-CS-RNTI); or the operating time of a retransmission timer (e.g., drx-RetransmissionTimerDL-PTM) corresponding to multicast (e.g., G-RNTI and / or G-CS-RNTI).

[0256] For example, a duration timer that supports duration timers / multicast indicates the length of time a terminal device waits after being awakened to receive control information (e.g., DCI).

[0257] For example, a multicast-compatible inactivity timer indicates the period after newly transmitted data or control information to schedule a new transmission.

[0258] For example, a multicast-compatible retransmission timer indicates the length of time a terminal device can receive multicast-compatible retransmissions (e.g., DCI, data, and resources).

[0259] For example, the validity period of the first multicast DRX is The operating time of the 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 operating time of the 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 operating time of the 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). It may include any one or more of the following.

[0260] For example, the validity period of the second DRX set may include any one or more of the validity periods of the DRX set corresponding to the 10th multicast service set, the validity period of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the 10th multicast service set, or the validity periods of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the second DRX set.

[0261] For example, the validity period of the second DRX set is The operating time of drx-onDurationTimerPTM, drx-InactivityTimerPTM, or drx-RetransmissionTimerDL-PTM for the G-RNTI set and / or G-CS-RNTI set corresponding to the second DRX set. It may include any one or more of the following.

[0262] It should be noted that the effective time of the second DRX set / multicast DRX / first multicast DRX may further include other times, and this is not limited to this application.

[0263] Optionally, this application may further include a terminal device receiving a configuration message for a second BWP. For example, the configuration for the second BWP may be carried in RRC-specific signaling (e.g., an RRC reconfiguration message) or broadcast message / system information (e.g., SIB1). This is not limited to this application.

[0264] The second BWP includes the active BWP.

[0265] Optionally, in this application, "the BWP configuration message includes information about the CFR" may include "the BWP includes the CFR".

[0266] For example, the configuration message for the second BWP includes the configuration message corresponding to the second BWP.

[0267] For example, "The configuration message of the second BWP includes information about the CFR" means that the configuration message of the second BWP includes information about the CFR.

[0281] The fourth set of cells is associated with the second set of DRX cells, and the fourth set of cells contains at least one cell.

[0282] For example, the second DRX set may include DRX corresponding to multicast / multicast services received by terminal devices and associated with the first cell set / first DRX, or DRX corresponding to multicast / multicast services in which terminal devices participate and are associated with the first cell set / first DRX, or DRX corresponding to multicast / multicast services associated with the first cell set / first DRX, or DRX corresponding to multicast / multicast services received by terminal devices and associated with the second BWP, or DRX corresponding to multicast / multicast services in which terminal devices participate and are associated with the second BWP, or DRX corresponding to multicast / multicast services associated with the second BWP.

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

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

[0377] For example, the validity period of the second multicast DRX is: The operating time of the duration timer (e.g., drx-onDurationTimerPTM) corresponding to the fourth multicast service (or third G-RNTI and / or third G-CS-RNTI), The operating time of the 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 operating time of the 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). It may include any one or more of the following.

[0378] For example, the validity period of the third DRX set may include any one or more of the validity periods of the DRX set corresponding to the 12th multicast service set, the validity period of the DRX set corresponding to the G-RNTI set and / or G-CS-RNTI set corresponding to the 12th multicast service set, or the validity periods 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 period of the third DRX set is The operating time of drx-onDurationTimerPTM, drx-InactivityTimerPTM, or drx-RetransmissionTimerDL-PTM for the G-RNTI set and / or G-CS-RNTI set corresponding to the third DRX set. It may include any one or more of the following.

[0380] It should be noted that the effective time of the third DRX set may include other times, but is not limited to this application.

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

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

[0383] Regarding the statement "the terminal device does not transmit a CSI (e.g., the first CSI) in the second cell set in the first time," it should be noted that this application is not limited to whether the terminal device transmits a CSI for the second cell set in a different cell or cell group.

[0384] Regarding the statement "the terminal device does not transmit a CSI for the second cell set (e.g., the first CSI) in the first time," please note that this application does not limit whether the terminal device transmits a CSI for another cell or cell set within the second cell set.

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

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

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

[0388] The sixth set of cells contains at least one cell.

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

[0390] For example, the second cell set may include cells other than those associated with the 12th multicast service set / 3rd DRX set, or cells other than the 6th cell set.

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

[0392] For example, if symbol n is not within the validity period of a unicast DRX, if the configuration message of an active BWP contains information about the CFR, and symbol n is within the validity period of a multicast DRX in which the terminal device participates, the terminal device will not send a semi-persistent CSI configured on PUSCH to any cell or set of cells other than the multicast-related cell (for example, the multicast-related cell in which symbol n is within the validity period of the multicast DRX), and / or the terminal device will not send a CSI on PUSCH.

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

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

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

[0396] For example, the first multicast service set may include multicast / multicast services that are received by terminal devices and for which multicast DRX is not configured, or multicast / multicast services that terminal devices participate in and for which multicast DRX is not configured, or multicast / multicast services for which multicast DRX is not configured, or multicast / multicast services that are received by terminal devices and associated with a second BWP and for which multicast DRX is not configured, or multicast / multicast services that terminal devices participate in and associated with a second BWP and for which multicast DRX is not configured, or multicast / multicast services that are 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 multicast / multicast services that are received by a terminal device and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that a terminal device participates in and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that are received by a terminal device, associated with a second BWP and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that a terminal device participates in, associated with a second BWP and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that are associated with a second BWP and for which a multicast DRX is not configured.

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

[0399] The eighth set of cells contains at least one cell.

[0400] For example, the fact that the second set of cells is not associated with the first set of multicast services can be understood as the second set of cells not being associated with the eighth set of cells.

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

[0402] For example, a terminal device has / contains three cells: cell 1, cell 2, and cell 3. The configuration message for the active BWP of cell 1 contains information about the CFR. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 1. A multicast DRX is configured for multicast 1, and there is no multicast DRX configured for multicast 2. If the first time is neither within the validity period of the unicast DRX nor within the validity period of the multicast DRX corresponding to multicast 1, the terminal device does not send the first CSI for cells 3 and 2 in the first time, the first DRX is a 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 period of a unicast DRX, and the configuration message of a valid BWP contains information about a CFR, and there is a multicast for which a multicast DRX is not configured, the terminal device will not send a semi-persistent CSI configured on PUSCH to any cell or set of cells other than the cell associated with the multicast for which a multicast DRX is not configured, and / or the terminal device will not send a CSI on PUSCH.

[0404] For example, the second cell set may include cell sets other than those associated with the 12th multicast service set / 3rd DRX set and cell sets associated with the first multicast service set, or cell sets other than the 6th and 8th cell sets.

[0405] For example, a terminal device contains / has three cells: cell 1, cell 2, and cell 3. The configuration messages of the valid BWPs for cell 1 and cell 2 contain information about the CFR. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 2. A multicast DRX is configured for multicast 1, and there is no multicast DRX configured for multicast 2. If the first time is not within the valid time of the unicast DRX but is within the valid time of the multicast DRX corresponding to multicast 1, the terminal device does not send the first CSI for cell 3 in the first time, the first DRX is a unicast DRX, the third DRX set is the 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 period of a unicast DRX and the configuration message of an active BWP contains information about the CFR, if symbol n is within the validity period of a multicast DRX in which the terminal device participates, and there is multicast for which no multicast DRX is configured, the terminal device will not send a semi-persistent CSI configured on PUSCH to cells or sets of cells other than the multicast-related cells (for example, the multicast-related cell for which symbol n is within the validity period of a multicast DRX) and to the multicast-related cells for which no multicast DRX is configured, and / or the terminal device will not send a CSI on PUSCH.

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

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

[0414] For example, the sixth set of cells is a subset of the first set of cells, or the sixth set of cells is equal to the first set of cells.

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

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

[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 DRX corresponding to multicast / multicast services received by terminal devices and associated with the first cell set / first DRX, or DRX corresponding to multicast / multicast services in which terminal devices participate and are associated with the first cell set / first DRX, or DRX corresponding to multicast / multicast services associated with the first cell set / first DRX, or DRX corresponding to multicast / multicast services received by terminal devices and associated with the second BWP, or DRX corresponding to multicast / multicast services in which terminal devices participate and are associated with the second BWP, or DRX corresponding to multicast / multicast services associated with the second BWP.

[0419] For example, the 12th multicast service set may include multicast / multicast services received by terminal devices and associated with the first cell set / first DRX, or multicast / multicast services in which terminal devices participate and are associated with the first cell set / first DRX, or multicast / multicast services associated with the first cell set / first DRX, or multicast / multicast services received by terminal devices and associated with the second BWP, or multicast / multicast services in which terminal devices participate and are associated with the second BWP.

[0420] For example, the second cell set may include cells other than those associated with the 12th multicast service set / 3rd DRX set in the first cell set, or cells other than the 6th cell set.

[0421] For example, a terminal device includes / has two DRX groups, the first DRX group corresponding to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponding to three cells, cell 4, cell 5, and cell 6. The configuration message for the valid 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 within the valid time of the multicast DRX corresponding to multicast 1, the terminal device does not send the first CSI at the first time for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 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 valid 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 multicast / multicast services that are received by terminal devices and associated with the first cell set / first DRX, for which no multicast DRX is configured; multicast / multicast services that terminal devices participate in and are associated with the first cell set / first DRX, for which no multicast DRX is configured; multicast / multicast services that are associated with the first cell set / first DRX, for which no multicast DRX is configured; multicast / multicast services that are received by terminal devices and associated with the second BWP, for which no multicast DRX is configured; multicast / multicast services that terminal devices participate in and are associated with the second BWP, for which no multicast DRX is configured; or multicast / multicast services that are associated with the second BWP, for which no multicast DRX is configured.

[0424] For example, the first multicast service set may include any one or more / all multicast / multicast services that are received by a terminal device, associated with the first cell set / first DRX, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that a terminal device participates in, associated with the first cell set / first DRX, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that are associated with the first cell set / first DRX, and for which no multicast DRX is configured; any one or more / all multicast / multicast services that are received by a terminal device, associated with the second BWP, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that a terminal device participates in, associated with the second BWP, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that are associated with the second BWP, and for which no multicast DRX is configured.

[0425] For example, the association of a first multicast service set / eighth cell set with a first DRX / first cell set can be understood as the same DRX parameters (e.g., parameters for 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 the eighth set of cells.

[0427] For example, the eighth set of cells is a subset of the first set of cells, or the eighth set of cells is equal to the first set of cells.

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

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

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

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

[0432] For example, a terminal device includes / has two DRX groups, the first DRX group corresponding to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponding to three cells, cell 4, cell 5, and cell 6. The configuration message of the active BWP for cell 1 contains information about the CFR. The terminal device receives multicast 1 in cell 1, and the terminal device receives multicast 2 in cell 1. There is no multicast DRX configured for multicast 1, and no multicast DRX configured for multicast 2. If the first time is not within the validity period of the first DRX group or the validity period of the multicast DRX corresponding to multicast 1, the terminal device does not send the first CSI at the first time for any cells in the first cell set other than cell 1 (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 period of one DRX group, and the configuration message of a valid BWP associated with the DRX group contains information about the CFR, and there is a multicast associated with the DRX group for which no multicast DRX is configured, then the terminal device will not send a semi-persistent CSI configured on PUSCH, and / or the terminal device will not send a CSI on PUSCH to any cell or set of cells other than those associated with the multicast for which no multicast DRX is configured on / within the DRX group.

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

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

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

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

[0438] It should be noted that there may be an intersection between the sixth and eighth sets of cells, or there may not be an intersection between them. This is not limited to 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. This is not limited to the present application.

[0440] For example, the second cell set may include, in the first cell set, cell sets other than those associated with the 12th multicast service set / 3rd DRX set and cell sets associated with the first multicast service set, or cell sets other than the 6th cell set and the 8th cell set.

[0441] For example, if symbol n is not within the lifetime of a DRX group, if the configuration message of the valid BWP associated with the DRX group contains information about the CFR, if symbol n is within the lifetime of a multicast DRX associated with a DRX group in which the terminal device participates, or if there is multicast associated with a DRX group for which no multicast DRX is configured, the terminal device will not send a semi-persistent CSI configured on PUSCH to cells or sets of cells other than the multicast-related cells (e.g., multicast-related cells for which symbol n is within the lifetime of a multicast DRX) and multicast-related cells for which no multicast DRX is configured on / within the DRX group, and / or the terminal device will not send a CSI on PUSCH.

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

[0443] In some embodiments, whether the first time falls within the valid time of the third DRX set can be determined by the terminal device.

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

[0445] The terminal device can optionally determine that the first time period belongs to the valid time period of the third DRX set. (1) The terminal device determines that the first time falls within the valid time of the third DRX set, based on or taking into consideration either or both of the allocations received in and / or before the fourth time (e.g., received multicast-related allocations) and multicast-related DRX Command MAC CEs, and / or (2) The terminal device may determine, based on or taking into consideration, either an assignment received in and / or before the fourth time (e.g., a received multicast-related assignment) and / or a multicast-related DRX Command MAC CE, that the first time does not belong to the valid time of the third DRX set.

[0446] A received allocation (for example, a received multicast-related allocation) may be an allocation received in the sixth cell set or the first cell set, and / or an allocation received for the twelfth multicast service set.

[0447] Optionally, multicast-related DRX Command MAC CEs may be multicast-related DRX Command MAC CEs received in the sixth cell set or the first cell set, and / or DRX Command MAC CEs relating to the twelfth multicast service set.

[0448] The fourth time is determined based on the lengths of the first and third time periods.

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

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

[0451] It should be understood that the fourth time may be the same as or different from the second time. This is not limited to the embodiments of this application.

[0452] It should be noted that the third time length may be the same as or different from the first time length. This is not limited to the embodiments of this application.

[0459] Optionally, the pre-set conditions include condition 3, and the first CSI can be / may include / be replaced with the fifth CSI.

[0460] The fifth CSI is Semi-persistent CSI, CSI, configured on PUSCH. Semi-persistent CSI configured on PUCCH, CSI is the layer 1 reference signal received power (L1-RSRP).

[0466] Optionally, the pre-set conditions include condition 3, and the method in this application may further include the satisfaction of condition 9.

[0467] For example, if conditions 3, 8, and 9 are met, the terminal device does not transmit the first CSI or the fifth CSI in the first time period.

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

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

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

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

[0488] Optionally, the pre-set conditions include condition 4, and the first CSI can be replaced with / may include / the sixth CSI.

[0489] Optionally, the pre-set conditions include condition 4, and "the terminal device does not transmit the first CSI at the first time" can be replaced with "the terminal device does not transmit the sixth CSI at the first time."

[0490] Optionally, the pre-set conditions include condition 4, and the pre-set conditions may further include condition 7.

[0491] Optionally, the pre-set conditions include condition 4, and the method in this application may further include the satisfaction of condition 7.

[0492] Optionally, the pre-set conditions include condition 4, and the pre-set conditions may further include condition 10.

[0493] Optionally, the pre-set conditions include condition 4, and the method in this application may further include satisfying condition 10.

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

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

[0496] For example, if CSI masking is configured for a terminal device, and the duration timer corresponding to the unicast does not operate for symbol n, and each active BWP configuration message does not contain information about the CFR, the terminal device will not send a CSI over the PUCCH.

[0497] For example, if CSI masking is configured for a terminal device, and the duration timer corresponding to one DRX group does not operate for symbol n, and the configuration message for each active BWP associated with the DRX group does not contain information about the CFR, the terminal device will not send a CSI over 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 duration of the unicast-compatible duration timer, or if the unicast-compatible duration timer is started or restarted, if CSI masking is configured for the terminal device, if the duration timer for one DRX group does not operate for symbol n, and the configuration message for each active BWP associated with the DRX group does not contain information about the CFR, the terminal device will not send a CSI over PUCCH for or in the DRX group.

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

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

[0501] For example, a multicast timer could be a duration timer that corresponds to multicast (e.g., drx-onDurationTimerPTM) or a duration timer related to multicast DRX (e.g., drx-onDurationTimerPTM).

[0502] For example, the second timer set may include multicast timers corresponding to multicast / multicast services received by the terminal device, or multicast timers corresponding to multicast / multicast services in which the terminal device participates, or multicast timers corresponding to multicast / multicast services received by the terminal device and associated with the second BWP, or multicast timers corresponding to multicast / multicast services in which the terminal device participates and is associated with the second BWP.

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

[0504] For example, the second timer set may be associated with the 13th multicast service set, and the 13th multicast service set may include the 7th multicast service.

[0505] For example, the 13th multicast service set may include multicast / multicast services received by terminal devices, or multicast / multicast services in which terminal devices participate.

[0506] For example, the 13th multicast service set may include one or all multicast / multicast services received by the terminal device, or one or all multicast / multicast services in which the terminal device participates.

[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 as a multicast service associated with the fourth G-RNTI and / or the fourth G-CS-RNTI.

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

[0509] It should be noted that during the operating time of the first multicast timer, the terminal device may also monitor other control information. This is not limited to the present application.

[0510] For example, the first multicast timer could 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, pre-set conditions include condition 5, and "the terminal device does not transmit the first CSI at the first time" may include "the terminal device does not transmit the first CSI at the first time for the first cell set."

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

[0513] For example, the first timer is a duration timer (e.g., drx-onDurationTimer) that corresponds to one DRX group (e.g., the first DRX group).

[0514] For a relevant explanation of "the terminal device does not transmit the first CSI at the first time for the first cell set," it should be understood that one should refer to the relevant explanation above. For brevity, further details will not be explained again.

[0515] Please note that for details regarding the second BWP, please refer to the explanation of Condition 2. Further details will not be explained here.

[0516] Optionally, the second BWP may include one or more active BWPs relating to 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 can be understood as containing 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] The fifth set of cells is associated with the second set of timers, and the fifth set of cells contains at least one cell.

[0521] For example, the second timer set may include multicast timers corresponding to multicast / multicast services received by a terminal device and associated with the first cell set / first timer / first DRX, or multicast timers corresponding to multicast / multicast services in which a terminal device participates and is associated with the first cell set / first timer / first DRX, or multicast timers corresponding to multicast / multicast services in which a terminal device participates and is associated with the first cell set / first timer / first DRX, or multicast timers corresponding to multicast / multicast services received by a terminal device and associated with the second BWP, or multicast timers corresponding to multicast / multicast services in which a terminal device participates and is associated with the second BWP, or multicast timers corresponding to multicast / multicast services in which a terminal device participates and is associated with the second BWP.

[0522] For example, the second timer set may include multicast timers that are received by the terminal device and correspond to one or all multicast / multicast services associated with the first cell set / first timer / first DRX, or multicast timers that the terminal device participates in and corresponds to one or all multicast / multicast services associated with the first cell set / first timer / first DRX, or multicast timers that correspond to one or all multicast / multicast services associated with the first cell set / first timer / first DRX, or multicast timers that are received by the terminal device and correspond to one or all multicast / multicast services associated with the second BWP, or multicast timers that the terminal device participates in and corresponds to one or all multicast / multicast services associated with the second BWP, or multicast timers that correspond to one or all multicast / multicast services associated with the second BWP.

[0523] For example, the 13th multicast service set may include multicast / multicast services received by a terminal device and associated with the first cell set / first timer / first DRX, or multicast / multicast services in which a terminal device participates and is associated with the first cell set / first timer / first DRX, or multicast / multicast services associated with the first cell set / first timer / first DRX.

[0524] For example, the 13th multicast service set may include one or all multicast / multicast services received by a terminal device and associated with the first cell set / first timer / first DRX, or one or all multicast / multicast services joined by a terminal device and associated with the first cell set / first timer / first DRX, or one or all 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 set of multicast services associated with the first cell set.

[0526] For example, a terminal device includes / has two DRX groups, the first DRX group corresponding to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponding to three cells, cell 4, cell 5, and cell 6. The configuration message for the valid 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 operate in the first time, and the timer of the multicast DRX corresponding to multicast 1 does not operate in the first time, the terminal device does not send the first CSI for the first DRX group / first cell set in the first time, the first timer is the timer of the first DRX group, the second timer set is the timer of the multicast DRX corresponding to multicast 1, 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 valid BWP of cell 1.

[0527] In some embodiments, whether a second set of timers operates at a first time can be determined by a terminal device.

[0528] Optionally, the non-operation of the second timer set during the first time period includes the terminal device determining that the second timer set will not operate during the first time period.

[0529] The terminal device may optionally decide that the second timer set does not activate. (1) The terminal device decides that the second timer set will not operate based on, or taking into consideration, either or both of the following: an assignment received in the eighth time and / or before the eighth time (e.g., a received multicast-related assignment) and / or a multicast-related DRX Command MAC CE, and / or (2) The terminal device may determine that the second timer set does not operate based on, or taking into consideration, either or both of the following: an assignment received in the eighth time and / or before the eighth time (e.g., a received multicast-related assignment) and / or a multicast-related DRX Command MAC CE, the received assignment (e.g., a received multicast-related assignment) may be an assignment received in the fifth cell set or the first cell set, and / or an assignment received relating to 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 relating to the thirteenth multicast service set.

[0530] The eighth time is determined based on the length of the first and seventh time periods.

[0531] For example, the interval between the eighth time and the first time is the length of the seventh time, and the eighth time precedes the first time.

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

[0533] Optionally, the pre-set conditions include condition 5, and the first CSI can be replaced with / may include / be replaced with the sixth CSI.

[0534] The 6th CSI is Semi-persistent CSI, periodic CSI, CSI configured over a physical uplink shared channel (PUSCH), Semi-persistent CSI configured on PUSCH, CSI configured on the physical uplink control channel (PUCCH), Periodic CSI composed on PUCCH, or Semi-persistent CSI configured on PUCCH It may include any one or more of the following.

[0535] Optionally, the pre-set conditions include condition 5, and the phrase "the terminal device does not transmit the first CSI at the first time" can be replaced with "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 is: The terminal device does not send a semi-persistent CSI. The terminal device does not transmit periodic CSI. The terminal device does not transmit the CSI configured on PUSCH. The terminal device does not transmit a semi-persistent CSI configured on PUSCH. The terminal device does not transmit the CSI configured on PUCCH. The terminal device does not transmit the periodic CSI configured on PUCCH. The terminal device does not transmit semi-persistent CSI configured on PUCCH. The terminal device does not send CSI over PUCCH. The terminal device does not transmit periodic CSI on PUCCH. The terminal device does not send semi-persistent CSI over PUCCH. The terminal device does not send CSI on PUSCH, or The terminal device does not send semi-persistent CSI on PUSCH. It may include any one or more of the following.

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

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

[0539] For example, if the duration timer corresponding to unicast does not operate for symbol n, and the configuration message of the valid BWP contains information about CFR, and the duration timer k corresponding to multicast does not operate for symbol n, the terminal device will not send a CSI over PUCCH.

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

[0541] Optionally, the pre-set conditions include condition 5, and the pre-set conditions may further include condition 7.

[0542] Optionally, the pre-set conditions include condition 5, and the method in this application may further include the satisfaction of condition 7.

[0543] Optionally, the pre-set conditions include condition 5, and the pre-set conditions may further include condition 10.

[0544] Optionally, the pre-set conditions include condition 5, and the method in this application may further include satisfying condition 10.

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

[0546] The first piece of information may indicate that the terminal device transmits CSIs during 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 limited to transmitting CSIs during 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 CSIs only during the operating time of a unicast timer (e.g., the first timer) and / or the operating time of a multicast timer.

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

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

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

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

[0551] Accordingly, when a terminal device obtains the first information, the terminal device does not send a CSI during the valid time other than the operating time of the unicast timer and / or the operating time of the multicast timer, or during the time other than the operating time of the unicast timer and / or the multicast timer, or the terminal device does not send a CSI on PUCCH.

[0552] Please note that "the terminal device obtains the first information" may or may not include / may include the CSI-mask being configured for the terminal device.

[0553] Please note that "The terminal device does not acquire the first information" may or may not include / may include the CSI-mask not being configured for the terminal device.

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

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

[0556] Optionally, the pre-set conditions include condition 5, and the pre-set conditions may further include condition 14.

[0557] Optionally, the pre-set conditions include condition 5, and the method in this application may further include satisfying condition 14.

[0558] For example, if conditions 5, 7, and 14 are met, the terminal device does not transmit the first CSI or the sixth CSI in the first time period.

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

[0560] For example, if conditions 5, 10, and 14 are met, the terminal device does not transmit the first CSI or the sixth CSI in the first time period.

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

[0562] For example, if conditions 5, 7, 10, and 14 are met, the terminal device does not transmit the first CSI or the sixth CSI in the first time period.

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

[0564] For example, if DCP is not configured for the terminal device, or symbol n is not within the duration of the duration timer corresponding to unicast, or if 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 operate for symbol n, if the configuration message of the valid BWP associated with the DRX group contains information about the CFR, or if each duration timer corresponding to multicast associated with the DRX group does not operate for symbol n, and multicast DRX is configured for each multicast associated with the DRX group in which the UE participates, the terminal device will not send a CSI over PUCCH for or in the DRX group.

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

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

[0567] Condition D: The third timer set is active in 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 at least one multicast timer may include a second multicast timer. During the operating time of the second multicast timer, the terminal device may monitor control information relating to the eighth multicast service.

[0569] For example, the third timer set may include multicast timers corresponding to multicast / multicast services received by the terminal device, or multicast timers corresponding to multicast / multicast services in which the terminal device participates, or multicast timers corresponding to multicast / multicast services received by the terminal device and associated with the second BWP, or multicast timers corresponding to multicast / multicast services in which the terminal device participates and is associated with the second BWP.

[0570] For example, the third timer set may be associated with the 14th multicast service set, and the 14th multicast service set may include the 8th multicast service.

[0571] For example, the 14th multicast service set may include multicast / multicast services received by a terminal device, or multicast / multicast services in which a terminal device participates, or multicast / multicast services received by a terminal device and associated with a second BWP, or multicast / multicast services in which a 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 as a multicast associated with the fifth G-RNTI and / or the fifth G-CS-RNTI.

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

[0574] It should be noted that during the operating time of the second multicast timer, the terminal device may also monitor other control information. This is not limited to the present application.

[0575] For example, the second multicast timer could 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 pre-set conditions include condition 6, and "the terminal device does not transmit the first CSI at the first time" may include "the terminal device does not transmit 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 in the first time" may be understood to include / include either the terminal device not transmitting a CSI (e.g., the first CSI) within the third cell set in the first time, or the terminal device not transmitting a CSI (e.g., the first CSI) for the third cell set in the first time.

[0578] Regarding the statement "the terminal device does not transmit a CSI (e.g., a first CSI) in the third cell set in the first time," please note that this application is not limited to whether the terminal device transmits a CSI for the third cell set in another cell or cell group.

[0579] Regarding the statement "the terminal device does not transmit a CSI for the third cell set (e.g., the first CSI) in the first time," please note that this application does not limit whether the terminal device transmits a CSI for another cell or cell set within the third cell set.

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

[0581] Optionally, the third set of cells is not associated with the 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 set of cells contains at least one cell.

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

[0585] For example, the third cell set may include cells other than those associated with the 14th multicast service set / third timer set, or cells other than those associated with the 7th cell set.

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

[0587] For example, if the duration timer corresponding to unicast does not operate for symbol n, if the configuration message of an active BWP contains information about the CFR, and the duration timer corresponding to multicast in which the terminal device participates operates for symbol n, the terminal device will not send a semi-persistent CSI configured on PUSCH to any cell or set of cells other than the multicast-related cell (for example, a multicast-related cell in which symbol n is within the validity period of the multicast DRX), and / or the terminal device will not send a CSI on PUCCH.

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

[0589] The second multicast service set includes at least one multicast service, and 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 a terminal device, or multicast / multicast services in which a terminal device participates, or multicast / multicast services received by a terminal device and associated with the second BWP, or multicast / multicast services in which a terminal device participates and is associated with the second BWP.

[0591] Multicast / multicast services received by a terminal device may be understood to include / are received / are currently received multicast / multicast services that will be received / are currently received by the terminal device, and / or multicast / multicast services in a configuration related to multicast / multicast services that are acquired by the terminal device.

[0592] For example, the second multicast service set may include multicast / multicast services that are received by terminal devices and for which multicast DRX is not configured, or multicast / multicast services that terminal devices participate in and for which multicast DRX is not configured, or multicast / multicast services for which multicast DRX is not configured, or multicast / multicast services that are received by terminal devices and associated with the second BWP and for which multicast DRX is not configured, or multicast / multicast services that terminal devices participate in and associated with the second BWP and for which multicast DRX is not configured, or multicast / multicast services that are 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 multicast / multicast services that are received by a terminal device and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that a terminal device participates in and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that are received by a terminal device, associated with a second BWP and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that a terminal device participates in, associated with a second BWP and for which a multicast DRX is not configured, or any one or more / all multicast / multicast services that are associated with a second BWP and for which a multicast DRX is not configured.

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

[0595] The ninth set of cells contains at least one cell.

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

[0597] For example, the third cell set may include cell / cell sets other than those related to the second multicast service set, or cell / cell sets other than the ninth cell set.

[0598] For example, a terminal device contains / 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. A multicast DRX is configured for multicast 1, and there is no multicast DRX configured for multicast 2. If the duration timer of the first DRX does not activate in the first time, and the duration timer of the multicast DRX corresponding to multicast 1 does not activate in the first time, the terminal device does not send the first CSI for cells 3 and 2 in the first time, the first DRX is a 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 unicast does not operate for symbol n, if the configuration message of an active BWP contains information about a CFR, and there is a multicast for which a multicast DRX is not configured, the terminal device will not send a semi-persistent CSI configured on PUSCH to cells or sets of cells other than those associated with the multicast for which a multicast DRX is not configured, and / or the terminal device will not send a CSI on PUSCH.

[0600] For example, the third cell set may include cell sets other than those associated with the 14th multicast service set / third timer set and cell sets associated with the second multicast service set, or cell sets other than the 7th and 9th cell sets.

[0601] For example, if the duration timer corresponding to unicast does not operate for symbol n, if the configuration message of an active BWP contains information about the CFR, if the duration timer corresponding to a multicast that the terminal device participates in operates for symbol n, and there is multicast for which a multicast DRX is not configured, the terminal device will not send a semi-persistent CSI configured on PUSCH to cells or sets of cells other than the multicast-related cells (for example, the multicast-related cell for which symbol n is within the validity period of the multicast DRX) and to the multicast-related cells for which a multicast DRX is not configured, and / or the terminal device will not send a CSI on PUSCH.

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

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

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

[0609] For example, the seventh set of cells is a subset of the first set of cells, or the seventh set of cells is equal to the first set of cells.

[0610] Optionally, the first cell set includes the third cell set and the seventh cell set.

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

[0612] For example, there is no intersection between the third set of cells and the seventh set of cells.

[0613] For example, the third timer set may include multicast timers corresponding to multicast / multicast services received by a terminal device and associated with the first cell set / first DRX / first timer, or multicast timers corresponding to multicast / multicast services in which a terminal device participates and is associated with the first cell set / first DRX / first timer, or multicast timers corresponding to multicast / multicast services in which a terminal device participates and is associated with the first cell set / first DRX / first timer, or multicast timers corresponding to multicast / multicast services received by a terminal device and associated with the second BWP, or multicast timers corresponding to multicast / multicast services in which a terminal device participates and is associated with the second BWP.

[0614] For example, the 14th multicast service set may include multicast / multicast services received by a terminal device and associated with the first cell set / first DRX / first timer, or multicast / multicast services in which a terminal device participates and is associated with the first cell set / first DRX / first timer, or multicast / multicast services in which a terminal device participates and is associated with the first cell set / first DRX / first timer, or multicast / multicast services received by a terminal device and associated with the second BWP, or multicast / multicast services in which a terminal device participates and is associated with the second BWP.

[0615] For example, the third cell set may include, in the first cell set, cells other than those related to the 14th multicast service set / third timer set, or cells other than the 7th cell set.

[0616] For example, a terminal device includes / has two DRX groups, the first DRX group corresponding to three cells, cell 1, cell 2, and cell 3, and the second DRX group corresponding to three cells, cell 4, cell 5, and cell 6. The configuration message of the active BWP for 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 in the first time, and the duration timer of the multicast DRX corresponding to multicast 1 operates in the first time, the terminal device does not send the first CSI in the first time for cells other than cell 1 in the first cell set (i.e., cell 2 and cell 3), the first timer is the duration timer of the first DRX group, 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 multicast / multicast services that are received by terminal devices and associated with the first cell set / first DRX, for which no multicast DRX is configured; multicast / multicast services that terminal devices participate in and are associated with the first cell set / first DRX, for which no multicast DRX is configured; multicast / multicast services that are associated with the first cell set / first DRX, for which no multicast DRX is configured; multicast / multicast services that are received by terminal devices and associated with the second BWP, for which no multicast DRX is configured; multicast / multicast services that terminal devices participate in and are associated with the second BWP, for which no multicast DRX is configured; or multicast / multicast services that are associated with the second BWP, for which no multicast DRX is configured.

[0619] For example, the second multicast service set may include any one or more / all multicast / multicast services that are received by a terminal device, associated with the first cell set / first DRX, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that a terminal device participates in, associated with the first cell set / first DRX, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that are associated with the first cell set / first DRX, and for which no multicast DRX is configured; received by a terminal device, associated with the second BWP, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that a terminal device participates in, associated with the second BWP, and for which no multicast DRX is configured; or any one or more / all multicast / multicast services that are associated with the second BWP, and for which no multicast DRX is configured.

[0620] For example, the association of a second multicast service set / ninth cell set with a first DRX / first cell set can be understood as the same DRX parameters (e.g., parameters for 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 the ninth set of cells.

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

[0623] Optionally, the first cell set includes the third cell set and the ninth cell set.

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

[0625] For example, there is no intersection between the third set of cells and the ninth set of cells.

[0626] For example, the third cell set may include, in the first cell set, cell / cell sets other than those related to the second multicast service set, or cell / cell sets other than the ninth cell set.

[0627] For example, if the duration timer corresponding to one DRX group does not operate for symbol n, and the configuration message of the active BWP associated with the DRX group contains information about the CFR, and there is multicast associated with the DRX group for which multicast DRX is not configured, the terminal device will not send a CSI on PUCCH for any cell or cell set other than the cell associated with the multicast for which multicast DRX is not configured on / within the DRX group.

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

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

[0630] For example, there is no intersection between the third set of cells and the ninth set of cells.

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

[0632] It should be noted that there may be an intersection between the seventh set of cells and the ninth set of cells, or there may not be an intersection between the seventh set of cells and the ninth set of cells. This is not limited to 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. This is not limited to the present application.

[0634] For example, the third cell set may include, in the first cell set, cell sets other than those associated with the 14th multicast service set / third timer set and cell sets associated with the second multicast service set, or cell sets other than the 7th and 9th cell sets.

[0635] For example, if the duration timer corresponding to one DRX group does not operate for symbol n, if the configuration message of the active BWP associated with the DRX group contains information about the CFR, if a terminal device joins and the duration timer corresponding to the multicast associated with the DRX group operates for symbol n, and there is multicast associated with the DRX group for which no multicast DRX is configured, the terminal device will not send a semi-persistent CSI configured on PUSCH, and / or the terminal device will not send a CSI on PUSCH to cells or sets of cells other than the multicast-related cells (for example, multicast-related cells for which symbol n is within the validity period of the multicast DRX) and multicast-related cells for which no multicast DRX is configured on / within the DRX group.

[0636] For example, a terminal device may transmit a first CSI in 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, a terminal device may transmit a first CSI in the first time for a cell or cell set associated with the second multicast service set. Alternatively, a terminal device may transmit a first CSI in the first time for a cell or cell set associated with the sixth multicast service.

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

[0638] The optional activation of a third timer set includes the terminal device deciding that the third timer set is activated.

[0639] The terminal device decides, by choice, that a third timer set is activated. (1) The terminal device determines that the third timer set will operate based on, or taking into consideration, either or both of the following: an assignment received at and / or before the 10th time (e.g., a received multicast-related assignment) and / or a multicast-related DRX Command MAC CE, and / or (2) A terminal device may determine that a third timer set is activated based on, or taking into consideration, either or both of the following: an assignment received at and / or before the 10th time (e.g., a received multicast-related assignment) and / or a multicast-related DRX Command MAC CE, wherein the received assignment (e.g., a received multicast-related assignment) may be an assignment received in the 7th cell set or the 1st cell set, and / or an assignment received relating to the 14th multicast service set. Optionally, the multicast-related DRX Command MAC CE may be a multicast-related DRX Command MAC CE received in the 7th cell set or the 1st cell set, and / or a DRX Command MAC CE relating to the 14th multicast service set.

[0640] The tenth time is determined based on the length of the first and ninth time periods.

[0641] For example, the interval between the 10th time and the 1st time is the length of the 9th time, and the 10th time precedes the 1st time.

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

[0643] Optionally, the pre-set conditions include condition 6, and the first CSI can be replaced with / may include / be replaced with the seventh CSI.

[0644] The 7th CSI is Semi-persistent CSI, periodic CSI, CSI configured over a physical uplink shared channel (PUSCH), Semi-persistent CSI configured on PUSCH, CSI configured on the physical uplink control channel (PUCCH), Periodic CSI composed on PUCCH, or Semi-persistent CSI configured on PUCCH It may include any one or more of the following.

[0645] Optionally, the pre-set conditions include condition 6, and "the terminal device does not transmit the first CSI at the first time" can be replaced with "the terminal device does not transmit the seventh CSI at the first time."

[0646] Optionally, the terminal device not transmitting the 7th CSI at the first time is: The terminal device does not send a semi-persistent CSI. The terminal device does not transmit periodic CSI. The terminal device does not transmit the CSI configured on PUSCH. The terminal device does not transmit a semi-persistent CSI configured on PUSCH. The terminal device does not transmit the CSI configured on PUCCH. The terminal device does not transmit the periodic CSI configured on PUCCH. The terminal device does not transmit semi-persistent CSI configured on PUCCH. The terminal device does not send CSI over PUCCH. The terminal device does not transmit periodic CSI on PUCCH. The terminal device does not send semi-persistent CSI over PUCCH. The terminal device does not send CSI on PUSCH, or The terminal device does not send semi-persistent CSI on PUSCH. It may include any one or more of the following.

[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 for the third cell set at the first time.

[0649] Optionally, the pre-set conditions include condition 6, and the pre-set conditions may further include condition 7.

[0650] Optionally, the pre-set conditions include condition 6, and the method in this application may further include the satisfaction of condition 7.

[0651] Optionally, the pre-set conditions include condition 6, and the pre-set conditions may further include condition 10.

[0652] Optionally, the pre-set conditions include condition 6, and the method in this application may further include satisfying condition 10.

[0653] For example, if CSI masking is configured for a terminal device, if the duration timer corresponding to unicast does not operate for symbol n, if the configuration message for an active BWP contains information about the CFR, if the duration timer corresponding to multicast operates for symbol n, and there is multicast for which no multicast DRX is configured, the terminal device will not send CSI over PUCCH to cells or sets of cells other than the multicast-related cells (for example, multicast-related cells for which symbol n is within the validity period of the multicast DRX) and / or multicast-related cells for which no multicast DRX is configured.

[0654] For example, if CSI masking is configured for a terminal device, if the duration timer corresponding to one DRX group does not operate for symbol n, if the configuration message of the active BWP associated with the DRX group contains information about the CFR, if the duration timer corresponding to the multicast associated with the DRX group operates for symbol n, and there is multicast associated with the DRX group for which no multicast DRX is configured, the terminal device will not send a CSI on PUCCH to cells or sets of cells other than multicast-related cells (for example, multicast-related cells where symbol n is within the validity period of the multicast DRX) and / or multicast-related cells for which no multicast DRX is configured on / within the DRX group, or to cells or sets of cells other than multicast-related cells (for example, multicast-related cells where symbol n is within the validity period of the multicast DRX) and / or multicast-related cells for which no multicast DRX is configured on / within the DRX group.

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

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

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

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

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

[0660] Condition 11 may also include the terminal device obtaining a fifth piece of information, which instructs the terminal device to send a CSI based on a multicast DRX (e.g., multicast DRX validity period and / or multicast DRX duration timer).

[0661] "Sending a CSI based on multicast DRX (e.g., multicast DRX expiration time and / or multicast DRX duration timer)" can be understood as any one or more of the following: sending a CSI based on unicast DRX (e.g., unicast DRX / DRX group expiration time and / or unicast DRX / DRX group duration timer), and sending a CSI based on multicast DRX (e.g., multicast DRX expiration time and / or multicast DRX duration timer). Multicast DRX (e.g., multicast DRX expiration time and / or multicast DRX duration timer) must be considered for sending a CSI. Unicast DRX (e.g., unicast DRX / DRX group expiration time and / or unicast DRX / DRX group duration timer) and multicast DRX (e.g., multicast DRX expiration time and / or multicast DRX duration timer) must be considered for sending a CSI.

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

[0663] The acquisition of the fifth piece of information by the terminal device may be carried out according to the method steps in the embodiments described above. For example, if the terminal device does not acquire the fifth piece of information, the terminal device must send a CSI based on the multicast DRX (e.g., the multicast DRX validity period and / or the multicast DRX duration timer).

[0664] Optionally, the fifth information may be transmitted to terminal devices by a 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 to this application. Optionally, among various terminal devices, some terminal devices may acquire the fifth information, while others may not. This is not limited to this application.

[0665] If condition 11 is not met, it can be understood that when a terminal device decides whether to send a CSI, it does not consider one or more of the following: whether the multicast DRX is within its valid time, whether the multicast timer is activated, whether the multicast DRX is configured for multicast, and whether the BWP configuration message contains information about multicast CFR.

[0666] For example, if condition 11 is not met, conditions 1, 2, or 3 may be replaced by the first time not falling within the valid time of the first intermittent reception (DRX). For example, if condition 11 is not met, conditions 4, 5, or 6 may be replaced by the first timer not operating during the first time.

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

[0668] 430: The terminal device sends a sixth piece of information to the network device indicating whether or not the terminal device can send a CSI based on multicast DRX (e.g., multicast DRX validity period and / or multicast DRX duration timer), and / or the terminal device sends a seventh piece of information to the network device indicating whether or not the terminal device wants to send a CSI based on multicast DRX (e.g., multicast DRX validity period and / or multicast DRX duration timer).

[0669] The sixth piece of information is used by the terminal device to report to the network device its ability to send a CSI based on multicast DRX (e.g., multicast DRX validity period and / or multicast DRX duration timer), and the seventh piece of information is used by the terminal device to report to the network device whether it wants to send a CSI or not, based on multicast DRX (e.g., multicast DRX validity period and / or multicast DRX duration timer). This helps the network device select a mode.

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

[0671] Please note that the order of steps in this embodiment of the present application is not limited herein.

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

[0673] It should be noted that in the methods provided in this embodiment of the present application, the cases in which a terminal device does not transmit a CSI (e.g., a first CSI) are limited to certain circumstances. It can be understood that a terminal device may transmit a CSI in circumstances other than those limited to in this embodiment of the present application.

[0674] In this embodiment of the present application, the terminal device does not transmit a first CSI at a first time if a pre-set condition is met. This solves the problem of how the terminal device reports a CSI in a scenario in which the BWP configuration message may or may not contain information about multicast CFRs, avoiding unnecessary CSI reporting and thereby reducing the power consumption of the terminal device.

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

[0676] 410: If the pre-configured conditions are met, the network device does not receive the first CSI at the first time.

[0677] For step 410, it should be understood that the relevant explanation in step 310 is needed. For example, in the technical measures in step 410, in some cases the terminal device does not send a CSI, and correspondingly the network device does not receive a CSI. Or, in some cases the terminal device sends a CSI, and correspondingly the network device receives a CSI. Or, the terminal device receives some information, for example, the first, second, and fifth pieces of information described above, and correspondingly the network device sends that information. Or, the terminal device does not receive some information, for example, the third and fourth pieces of information described above, and correspondingly the network device does not send that information. Or, the terminal device sends some information, for example, the sixth and seventh pieces of information described above, and correspondingly the network device receives that information. For brevity, further details are not explained here.

[0678] Please note that "not receiving the first CSI" may be understood to include / be interpreted as including any one or more of not decoding / analyzing the CSI (e.g., the first CSI).

[0679] It should be noted that "the network device does not receive the first CSI at a first time" may be understood to include / include any one or more of the following: the network device does not receive a CSI (e.g., the first CSI) on the PUCCH at a first time; the network device does not decode a CSI (e.g., the first CSI) on the PUSCH at a first time; the network device decides not to receive the first CSI at a first time; and the network device decides that the terminal device does not transmit the first CSI at a 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 pre-configured condition is met. This solves the problem of how a network device receives a CSI in a scenario in which the BWP configuration message may or may not contain information about multicast CFRs. A feasible method is provided. When a CSI is received, the network device not only considers unicast DRX and / or multicast DRX (or multicast), but also considers whether the BWP configuration message contains information about multicast CFRs, so that when receiving a CSI or decoding / analyzing data / CSI, the network device can correctly determine whether a CSI is present. This helps improve the accuracy of decoding and improves communication quality (e.g., improve reliability). In this way, the network device does not always need to receive a CSI, thereby saving energy for the network device. In addition, the network device can use PUCCH resources that do not receive CSIs, thereby improving resource utilization.

[0681] Note that in the embodiment of Figure 3 and / or the embodiment of Figure 4, the first CSI may be replaced by a first SRS (Sounding Reference Signal), and the CSI may be replaced by an SRS. This may be used as another embodiment or two embodiments. The other embodiment or two embodiments may be used in combination with the embodiment of Figure 3 and / or the embodiment of Figure 4, or as independent embodiments.

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

[0683] For example, a terminal device will not transmit a first CSI and / or a first SRS at a first time if pre-configured conditions are met.

[0684] Problem 2: In conventional technology, when a terminal device is switched to BWP, even if the BWP configuration message does not contain information about multicast CFR, the multicast DRX timer on the terminal device continues to operate, and the multicast DRX remains active. Therefore, the terminal device also transmits CSI and / or SRS. However, if the configuration message of the terminal device's active BWP does not contain information about multicast CFR, the terminal device cannot (or may not) receive multicast services / data, or does not receive multicast services / data at all. It can be understood that in this case, transmitting CSI and / or SRS is meaningless, and the terminal device's power consumption may increase.

[0685] Hereinafter, with reference to Figure 5, another communication method provided in the embodiments of this application will be described.

[0686] 510: If the terminal device is switched to a third BWP, the terminal device stops the timer that corresponds to multicast DRX.

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

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

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

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

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

[0692] For example, "Switch to the third BWP" could include enabling the third BWP.

[0693] The timers that support multicast DRX include one or more of the fourth timer, fifth timer, sixth timer, and seventh timer.

[0694] The fourth timer is a duration timer that supports multicast DRX (for example, drx-onDurationTimerPTM).

[0695] The fifth timer is an inactivity timer (e.g., drx-InactivityTimerPTM) that corresponds to multicast DRX.

[0696] The sixth timer is a retransmission timer that corresponds to multicast DRX (for example, drx-RetransmissionTimerDL-PTM).

[0697] The seventh timer is an RTT timer that corresponds 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 a terminal device waits after being awakened to receive control information (e.g., DCI).

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

[0700] For example, a retransmission timer for multicast DRX indicates the length of time a terminal device will receive multicast-compatible retransmissions (e.g., DCI, data, and resources).

[0701] Optionally, timers that support multicast DRX include timers that support all multicast DRX.

[0702] Optionally, the timers corresponding to multicast DRX include timers corresponding to multicast DRX associated with the third BWP.

[0703] Optionally, the timers that support multicast DRX include timers that support all multicast DRX and are associated with a third BWP.

[0704] In this embodiment of the present application, if a terminal device is switched to a third BWP and the configuration message of the third BWP does not contain information about the CFR, the terminal device stops the timer corresponding to the multicast DRX. This avoids unnecessary CSI reporting and thereby reduces the power consumption of the terminal device.

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

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

[0707] For step 610, it should be understood that the relevant explanation in step 510 is necessary. For example, in the technical measures in step 610, in some cases, the terminal device stops the timer corresponding to multicast DRX, and in response, the network device stops the timer corresponding to multicast DRX. For brevity, the details will not be explained again here.

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

[0709] Problem 3: In conventional technology, when multicast DRX is configured for a terminal device, the multicast DRX timer on the terminal device (e.g., drx-onDurationTimerPTM) is started, and the multicast DRX is within its active time. Therefore, the terminal device sends a CSI and / or SRS. However, if the valid BWP configuration message on the terminal device does not contain information about multicast CFR, the terminal device may not receive (or may not receive) multicast services / data, or the terminal device may not receive multicast services / data at all. In this case, sending a CSI and / or SRS is meaningless, and it can be understood that the terminal device's power consumption may increase.

[0710] Hereinafter, with reference to Figure 7, another communication method provided in the embodiments of this application will be described.

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

[0712] For example, the fourth BWP is the active BWP of the terminal device.

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

[0714] Optionally, for a terminal device to perform multicast DRX may include the terminal device starting an eighth timer and / or the terminal device monitoring the PDCCH during the multicast DRX's lifetime.

[0715] The eighth timer is a duration timer that corresponds to multicast DRX (for example, drx-onDurationTimerPTM).

[0716] Optionally, a terminal device starting an eighth timer may include the terminal device starting the eighth timer after drx-SlotOffsetPTM from 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 multicast DRX offset.

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

[0720] For example, drx-LongCyclePTM indicates the duration of a DRX cycle. For example, drx-StartOffsetPTM indicates the subframe in which a DRX cycle begins. For instance, drx-StartOffsetPTM is used when calculating the frame number and subframe number for the start opportunity of drx-onDurationTimerPTM. It can be understood that drx-StartOffsetPTM is used to determine the subframe within a frame in which drx-onDurationTimerPTM begins.

[0721] For example, drx-SlotOffsetPTM indicates the delay before the start of drx-onDurationTimerPTM and is an offset used when the opportunity to start drx-onDurationTimerPTM is calculated within a subframe. For example, the range of values ​​for drx-SlotOffsetPTM is from 0ms to (31 / 32)ms, with a precision of (1 / 32)ms. After a terminal device determines, based on drx-SlotOffsetPTM, which subframe in which drx-onDurationTimerPTM will start, it can be understood that the terminal device then determines, based on drx-SlotOffsetPTM, the specific (1 / 32)ms within that subframe (i.e., the subframe determined based on drx-StartOffset) in which drx-onDurationTimerPTM will start.

[0722] Optionally, a multicast DRX may be associated with any one or more of the following: 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 following: multicast DRX, multicast service 15, G-RNTI 6, and G-CS-RNTI 6.

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