[0043] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0044] 1. Introduction to eXtended Reality (XR)

[0045] XR services include augmented reality (AR), virtual reality (VR) and mixed reality (MR). Currently, popular XR services use H.264 encoding technology to achieve image data compression, save traffic and ensure image quality. The existing H.264 technology encodes image data into three types of image frames:

[0046] I frame, i.e. intra-coded picture, is a complete picture frame that can be generated and presented independently of other frames.

[0047] P frame, i.e. predicted picture, contains only the image change information relative to the previous frame. The receiver needs to combine the previous frame to generate the current frame and display it on the receiving terminal.

[0048] B frame, namely Bidirectional predicted picture, is used to indicate the change information of the current frame relative to the previous frame and the following frame. The receiver needs to combine the previous frame and the following frame to generate the current frame.

[0049] The above-mentioned front frames and back frames are sorted according to the frame presentation time or the image acquisition time of the source end. The actual sending and receiving time may be adjusted according to the image decoding time of the receiver. For example, the sender can send according to the order of the image frame decoding time of the receiver.

[0050] Different frame types correspond to different frame encoding methods, resulting in different degrees of image compression. Among them, the compression degree of I frame is relatively low (that is, the frame data volume is the largest), the compression degree of P frame is moderate (that is, the frame data volume is moderate), and the compression degree of B frame is the highest (that is, the frame data volume is the smallest).

[0051] There are two ways to transmit XR images, one based on frame slice combination and the other based on frame set (Group of Pitcture, GoP).

[0052] Among them, the transmission method based on slice combination: a data frame is cut into multiple data blocks, and then the blocks of multiple image frames are dispersed and combined into multiple data blocks for transmission, so as to achieve the purpose of smoothing the flow of XR business data flow. This method greatly reduces the flow fluctuation caused by the difference in the amount of I / P / B frame data, but due to the cross transmission between graphic frames, the transmission delay of image frames is significantly increased;

[0053] Transmission methods based on frame sets, such as Figure 2As shown in the figure: According to the periodic characteristics of the video stream, the video frames are divided into video frame combinations according to the period of the I frame. An I frame and all the P frames and B frames from the subsequent frame to the next I frame constitute a frame combination. The image frames are transmitted and played at the receiving end according to the frame period. The time interval between the frame arrival times of adjacent image frames is a frame period. The transmission method based on the frame set avoids mixed transmission between image frames, so that the generated image frames are transmitted in time. Due to the different compression levels between I, P, and B frames, the frame data rate fluctuates.

[0054] 2. Protocol Data Unit (PDU) set

[0055] Currently in the relevant discussions of 3GPP, XR's business data is modeled as a PDU set. A PDU set includes a group of PDUs, so that the quality of service (QoS) is managed according to the PDU set when the data is transmitted in the wireless network. According to the above-mentioned different video data transmission methods, a PDU set can correspond to an image frame, for example, a complete P frame or B frame, or an XR business data slice; another image frame can contain several PDU sets. For example, when the image frame is transmitted according to the left and right eye lines of sight, the left eye image data of an image frame corresponds to a PDU set, and the right eye image data corresponds to another PDU set; in addition, when the image is transmitted in the visual axis direction and the non-visual axis direction, the image data in the visual axis direction corresponds to one PDU set, and the image data in the non-visual axis direction corresponds to another PDU set. The above is only an example to illustrate the modeling of the PDU set. The modeling of the PDU set may take other forms and does not constitute a limitation on the implementation methods of the present application.

[0056] 3. Transmission of XR Services in NR Networks

[0057] According to the current 3GPP protocol, when an uplink XR data packet of the UE arrives at the Packet Data Convergence Protocol (PDCP) layer buffer from the application layer, the PDCP discard timer (PDCP discardTimer) will be started according to the initial value of the base station pre-configured value. During the operation of the PDCP discardTimer, the base station can schedule the UE to transmit the data packet to the base station. If the corresponding PDCP discardTimer times out and the data is still not successfully transmitted, the data packet is discarded.

[0058] 4. NR measurement interval

[0059] When it is necessary to perform neighbor cell measurements, the receiving channel needs to be used; when performing measurements, one or more parameters (frequency, beam parameters, receiving signal equalization algorithm, etc.) used by the receiving channel to perform measurements are different from the corresponding parameters used to perform data reception; in this case, the same receiving channel cannot perform measurement and data reception tasks at the same time. When the UE's receiving channel is used for measurement, the UE will not be able to receive data, resulting in a measurement interval. The configuration parameters related to the measurement interval include the period and offset of the measurement interval, the length of the measurement interval, etc. For a diagram of the measurement interval, see Figure 3 According to the current 3GPP protocol, during a UE's measurement interval, the UE cannot perform data transmission.

[0060] 5. Non-transmittable time window

[0061] Due to hardware limitations, in order to ensure normal measurement, the UE needs to suspend the use of the receiving channel to perform data reception and instead perform the measurement task. The resulting measurement window is the measurement interval. The UE performs the measurement task within the measurement interval. Due to the software and hardware correlation between uplink transmission and downlink reception and the correlation between uplink and downlink data / signaling transmission, uplink transmission is sometimes restricted or impossible within the measurement interval.

[0062] In addition, when the UE's transceiver channel parameters need to be adjusted or used for other purposes, for example, switching cells or carriers, switching bandwidth parts (Bandwidth Part, BWP), carrier activation or deactivation, etc., the UE needs to adjust the transceiver channel to a new frequency range or perform a random access process, and cannot perform data transmission and reception at the same time, thus generating a data non-transmission time window.

[0063] 6. Discontinuous Reception (DRX) Mechanism

[0064] The description of NR connected state DRX has been defined in the relevant protocols. According to the DRX definition, DRX is configured with a periodic time window in the active state. The UE needs to remain active at least in the activation window (defined by the DRX receive duration timer (drx-onDurationTimer)), including receiving scheduling from the base station, downlink data reception and uplink data transmission. If there is scheduling command reception or data transmission during the activation window, the UE needs to extend the active state time according to the predefined mechanism (for example, a mechanism based on the DRX inactivity timer (drx-InactivityTimer)) and preconfigured parameters in order to receive or send more data.

[0065] The Radio Resource Control (RRC) controls the operation of DRX by configuring the following DRX parameters:

[0066] drx-onDurationTimer: duration when the DRX cycle starts;

[0067] DRX slot offset (drx-SlotOffset): delay before starting drx-onDurationTimer;

[0068] drx-InactivityTimer: the duration after a PDCCH event occurs, where the Physical Downlink Control Channel (PDCCH) indicates that the Media Access Control (MAC) entity has made a new uplink (UL) or downlink (DL) transmission;

[0069] DRX downlink retransmission timer (drx-RetransmissionTimerDL) (for each DL Hybrid Automatic Repeat reQuest (HARQ) process except the broadcast process): the maximum duration until a DL retransmission is received;

[0070] DRX uplink retransmission timer (drx-RetransmissionTimerUL) (per UL HARQ process): maximum duration until a UL retransmission grant is received;

[0071] DRX long cycle start offset (drx-LongCycleStartOffset): defines the long DRX cycle (DRX cycle) and DRX start offset (drx-StartOffset) of the subframe where the long DRX and short DRX cycles start;

[0072] DRX short cycle (drx-ShortCycle): short DRX cycle, where drx-ShortCycle is an optional parameter;

[0073] DRX short cycle timer (drx-ShortCycleTimer): The terminal should follow the duration of the short DRX cycle, where drx-ShortCycleTimer is an optional parameter;

[0074] DRX Downlink HARQ Round Trip Timer (drx-HARQ-RTT-TimerDL) (for each DL HARQ process except the broadcast process): the minimum duration that the MAC entity expects before allocating a DL for a HARQ retransmission;

[0075] DRX Uplink HARQ Round Trip Timer (drx-HARQ-RTT-TimerUL) (per UL HARQ process): minimum duration expected by the MAC entity before UL HARQ retransmission;

[0076] Power-saving wakeup (ps-Wakeup): Start the configuration of the related drx-onDurationTimer when the downlink control information (DCI with CRC scrambled by PS-RNTI, DCP) with cyclic redundancy check (CRC) scrambled by PS-RNTI (Power Saving Radio Network Temporary Identity, PS-RNTI) is monitored but not detected, where the ps-Wakeup is an optional parameter;

[0077] Energy-saving transmission of other periodic CSI (ps-TransmitOtherPeriodicCSI): configures the periodic CSI of reporting non-Layer 1 Reference Signal Received Power (L1-RSRP) on the Physical Uplink Control Channel (PUCCH) within the time period specified by drx-onDurationTimer when DCP is configured but the related drx-onDurationTimer is not started. The ps-TransmitOtherPeriodicCSI is an optional parameter.

[0078] Energy-saving transmission periodic L1-RSRP (ps-TransmitPeriodicL1-RSRP): If DCP is configured but the related drx-onDurationTimer is not started, periodic CSI, i.e. L1-RSRP, is sent on PUCCH at the time interval specified by drx-onDurationTimer, where ps-TransmitPeriodicL1-RSRP is an optional parameter.

[0079] The protocol for the UE to determine the activation time according to the timer configured by DRX is described as follows:

[0080] When DRX is configured, the activation time of the serving cells in the DRX group includes the following times:

[0081] The drx-onDurationTimer or drx-InactivityTimer configured for the DRX group is running; or,

[0082] The drx-RetransmissionTimerDL, drx-RetransmissionTimerUL or drx-RetransmissionTimerSL of any serving cell in the DRX group is running.

[0083] It can be seen that when any of the following DRX timers is running, the UE should be in an active state and can receive scheduling from the base station for data transmission and reception: drx-onDurationTimer, drx-InactivityTimer drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, drx-RetransmissionTimerSL.

[0084] The following is a detailed description of the discontinuous reception control method provided by the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0085] See also Figure 4 , Figure 4 is a flow chart of a discontinuous reception control method provided by an embodiment of the present application, which can be executed by a terminal, such as Figure 4 As shown, the following steps are included:

[0086] Step 401: The terminal performs DRX control according to a relative position relationship between a first time window and a first activation time;

[0087] The first time window is a time window in which data cannot be transmitted, and the first activation time is an activation time of the terminal determined according to the DRX configuration.

[0088] In this embodiment, the first time window is a time window in which data cannot be transmitted, for example, a time window in which data cannot be transmitted due to measurement or adjustment of radio frequency parameters of the transceiver channel. It should be noted that the first time window can also be called a non-transmittable time window.

[0089] The above-mentioned DRX configuration may include DRX parameters for controlling DRX operation. For example, the above-mentioned DRX configuration may include but is not limited to at least one of the following: drx-onDurationTimer, drx-SlotOffset, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, drx-LongCycleStartOffset, drx-ShortCycle, drx-ShortCycleTimer, drx-HARQ-RTT-TimerDL, drx-HARQ-RTT-TimerUL, ps-Wakeup, ps-TransmitOtherPeriodicCSI, ps-TransmitPeriodicL1-RSRP.

[0090] In some optional embodiments, the first activation time may be determined according to the DRX timer in the DRX configuration. Exemplarily, the first activation time may include the operating time period of the DRX timer, for example, the first activation time may include the operating time period of at least one of drx-onDurationTimer, drx-InactivityTimer drx-RetransmissionTimerDL, drx-RetransmissionTimerUL and drx-RetransmissionTimerSL. It should be noted that the terminal is in an active state during the activation time and can receive the scheduling of the network side device to send and receive data.

[0091] The relative position relationship between the first time window and the first activation time can be used to indicate whether the first time window overlaps with the first activation time. Exemplarily, when there is no overlap between the first time window and the first activation time, the terminal can send and receive data based on the first activation time; when there is overlap between the first time window and the first activation time, the terminal can adjust the activation time of the terminal, for example, it can compensate for the length of time the activation time of the terminal is occupied by the first time window; or, it can control the suspension or stop of the application of the DRX configuration according to the first time window, for example, suspend or stop the application of the DRX configuration in the second time window determined according to the first time window. Since the terminal is in the activation time during the time period of suspending or stopping the application of the DRX configuration, the network side device can have more time to schedule the terminal for data transmission, thereby reducing the impact of the first time window on the data transmission of the terminal.

[0092] The discontinuous reception control method provided in the embodiment of the present application is that the terminal performs DRX control according to the relative position relationship between the first time window and the first activation time; wherein the first time window is a time window in which data cannot be transmitted, and the first activation time is the activation time of the terminal determined according to the DRX configuration. Since the relative position relationship between the first time window and the first activation time is taken into account when performing DRX control, this is conducive to reducing the impact of the first time window on the data transmission of the terminal, and further helps to improve the reliability of data transmission.

[0093] Optionally, the terminal performs DRX control according to a relative position relationship between the first time window and the first activation time, including:

[0094] In a case where there is an overlap between the first time window and the first activation time, the terminal performs a first operation, where the first operation includes at least one of the following:

[0095] adjusting the activation time of the terminal;

[0096] Determine a second time window as the activation time of the terminal, the second time window being a time window determined according to the first time window;

[0097] suspending or stopping application of part or all of the DRX configuration within the second time window;

[0098] The DRX configuration is applied after a second time window.

[0099] In this embodiment, the second time window may at least cover part or all of the first time window.

[0100] It is understandable that, in the case where there is an overlap between the first time window and the first activation time, the first time window will occupy at least part of the activation time of the terminal. If the terminal still receives data based on the occupied activation time and receives and sends data, it is easy to affect the data transmission quality, especially the data transmission quality of delay-sensitive services. Therefore, in the embodiment of the present application, when there is an overlap between the first time window and the first activation time, the terminal performs the first operation to reduce the impact of the first time window on data transmission. The following examples are given for different situations.

[0101] In case one, when there is an overlap between the first time window and the first activation time, the terminal adjusts the activation time of the terminal, for example, the length of the activation time of the terminal or the position of the activation time of the terminal can be adjusted to reduce the overlapping part between the activation time of the terminal and the first time window, thereby reducing the impact of the first time window on data transmission.

[0102] In case 2, when there is an overlap between the first time window and the first activation time, the terminal determines the second time window as the activation time of the terminal, so that the network side device can schedule the terminal more flexibly.

[0103] Case three, when there is an overlap between the first time window and the first activation time, the terminal suspends or stops applying part or all of the DRX configuration in the second time window, that is, the terminal does not use the DRX mechanism to send and receive data in the second time window, or all or part of the operating behaviors based on the DRX configuration are canceled in the second time window, so that the network side equipment can schedule the terminal more flexibly.

[0104] It should be noted that, when the DRX configuration is suspended, the relevant parameters of the DRX configuration may retain the parameter values ​​when it is suspended, or the relevant parameters of the DRX configuration are not initialized or reset; when the DRX configuration is stopped, the relevant parameters of the DRX configuration may be initialized or reset.

[0105] Case 4: When there is an overlap between the first time window and the first activation time, the terminal applies the DRX configuration after the second time window, and the terminal may not apply the DRX configuration or stop applying the DRX configuration or suspend applying the DRX configuration before the end of the second time window, so that the network side device can schedule the terminal more flexibly. For example, the terminal starts to apply the DRX configuration before the second time window, suspends or stops applying the DRX configuration within the second time window, and continues to apply the DRX configuration after the end of the second time window.

[0106] Optionally, the first activation time is an activation time determined according to a DRX timer;

[0107] The adjusting the activation time of the terminal includes at least one of the following:

[0108] Adjusting the initial value of the DRX timer;

[0109] Adjusting the start time of the DRX timer;

[0110] Restarting the DRX timer at or after an end time of the first time window;

[0111] The DRX timer is suspended at a first moment, and continues to run at or after an end moment of the first time window, wherein the first moment is a start moment at which the first activation time overlaps the first time window.

[0112] Exemplarily, the first activation time may include an operating time period of the DRX timer. Optionally, the DRX timer includes at least one of the following:

[0113] DRX receive duration timer drx-onDurationTimer;

[0114] DRX inactivity timer drx-InactivityTimer;

[0115] DRX downlink retransmission timer drx-RetransmissionTimerDL;

[0116] DRX uplink retransmission timer drx-RetransmissionTimerUL;

[0117] DRX side link retransmission timer drx-RetransmissionTimerSL.

[0118] Among them, the above-mentioned drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL and drx-RetransmissionTimerSL can refer to the above-mentioned related instructions and are not repeated here.

[0119] The initial value (Initial Value) of the DRX timer can be understood as the timing duration of the DRX timer, that is, the DRX timer times out after running the initial value after being started.

[0120] In one embodiment, when there is an overlap between the first time window and the first activation time, the terminal can adjust the initial value of the DRX timer, for example, the initial value of the DRX timer can be increased to compensate for the portion of the terminal's activation time occupied by the first time window.

[0121] In another embodiment, when there is an overlap between the first time window and the first activation time, the terminal can adjust the start time of the DRX timer, for example, postpone the start time of the DRX timer to after the above-mentioned first time window, so that the adjusted activation time of the terminal does not overlap with the first time window.

[0122] In another embodiment, when there is an overlap between the first time window and the first activation time, the terminal can adjust the activation time of the terminal by restarting the DRX timer. Specifically, when the terminal determines that there is or will be a first time window that squeezes the activation time defined by the terminal according to the DRX timer, the terminal restarts the DRX timer at or after the end of the first time window.

[0123] In another embodiment, when there is an overlap between the first time window and the first activation time, the terminal can adjust the activation time of the terminal by suspending the operation of the DRX timer. Specifically, when there is an overlap between the first time window and the activation time defined by the DRX timer (i.e., the operation time of the DRX timer), the terminal can suspend the operation of the DRX timer and continue to run the DRX timer at or after the end of the first time window.

[0124] It should be noted that the above-mentioned continuing to run the DRX timer at or after the end time of the first time window can be understood as continuing to run the DRX timer at or after the end time of the first time window according to the remaining timing duration of the DRX timer at the suspension time. For example, if the above-mentioned DRX timer is started at time t1, the initial value is T1, and it is suspended at time t2, then the remaining timing duration of the above-mentioned DRX timer at time t2 is: T1-(t2-t1), and at or after the end time of the first time window, the DRX timer continues to run according to T1-(t2-t1).

[0125] Optionally, the first activation time is an activation time determined according to the DRX timer when the initial value of the DRX timer is a first initial value;

[0126] The adjusting the initial value of the DRX timer includes:

[0127] Adjusting the initial value of the DRX timer from the first initial value to a second initial value;

[0128] The second initial value is agreed upon by a protocol or configured by a network side device, or the second initial value is determined based on at least one of the following: the first initial value, the first time window, the overlapping part between the first time window and the first activation time, and the first offset value.

[0129] The first offset value may be agreed upon by a protocol or configured by a network-side device. The second initial value may be greater than the first initial value.

[0130] Exemplarily, the network side device may configure a first initial value and a second initial value for the DRX timer, wherein the second initial value is greater than the first initial value, and the initial value of the DRX timer adopts the first initial value by default. In the case where the initial value of the DRX timer is the first initial value, if there is an overlap between the activation time of the terminal determined according to the operating time period of the DRX timer and the first time window, the initial value of the DRX timer may be adjusted to adopt the second initial value.

[0131] Optionally, the second initial value is one of the following:

[0132] The sum of the first initial value and the length of the first time window;

[0133] a sum of the first initial value and the length of the overlapping portion between the first time window and the first activation time;

[0134] The sum of the first initial value and the first offset value.

[0135] In some optional embodiments, multiple offset values ​​can be agreed upon by a protocol or configured by a network-side device, and the first offset value can be the offset value with the smallest difference with the first duration among the multiple offset values, wherein the first duration is the length of the overlapping part between the first time window and the first activation time.

[0136] Optionally, the adjusting the start time of the DRX timer includes:

[0137] The start time of the DRX timer is adjusted to the end time of the first time window or later.

[0138] In this embodiment, the start time of the DRX timer is adjusted to the end time of the first time window or later, so that the running time period of the adjusted DRX timer does not overlap with the first time window.

[0139] It should be noted that, when adjusting the start time of the DRX timer, the initial value of the DRX timer may be changed or may remain unchanged, which is not limited in this embodiment.

[0140] Optionally, the suspending or stopping applying part or all of the DRX configuration within the second time window includes at least one of the following:

[0141] Not starting a DRX timer used to determine an activation time or a sleep time of the terminal within the second time window;

[0142] The terminal does not enter a sleep time period according to the timeout of the DRX timer within the second time window.

[0143] Exemplarily, for the DRX timer used to determine the activation time or sleep time of the terminal not being started within the second time window, it can be understood that the terminal is always in the activation time within the second time window, that is, the above-mentioned second time window is the activation time of the terminal. In this way, the network side device can have more time to schedule the terminal for data transmission, thereby reducing the impact of the first time window on data transmission and improving the reliability of data transmission.

[0144] Exemplarily, for not determining whether the terminal enters the sleep time based on the expiration of the DRX timer within the second time window, it can be understood that if the DRX timer used to determine the activation time or sleep time of the terminal times out within the second time window, the terminal is not considered to enter the sleep time, but continues to be considered to be in the activation time. This allows the network side device to have more time to schedule the terminal for data transmission, thereby reducing the impact of the first time window on data transmission and improving the reliability of data transmission.

[0145] Optionally, the first operation includes suspending or stopping applying part or all of the DRX configuration within the second time window, and the method further includes at least one of the following:

[0146] The terminal calculates, within the second time window, a start time of the drx-onDurationTimer according to a DRX cycle and an offset parameter;

[0147] The terminal calculates the DRX cycle start time or end time according to the DRX cycle and offset parameter within the second time window;

[0148] When the second moment is outside the second time window, the terminal cancels the suspension of applying the DRX configuration or continues to apply the DRX configuration from the second moment; wherein the second moment is the start moment of the drx-onDurationTimer calculated according to the DRX cycle and offset parameters, or the second moment is the start moment or end moment of the DRX cycle calculated according to the DRX cycle and offset parameters.

[0149] In this embodiment, the terminal calculates the start time of drx-onDurationTimer or the start time of the DRX cycle or the end time of DRX according to the DRX cycle and offset parameters within the second time window. This is conducive to canceling the suspension of the DRX configuration or continuing to apply the DRX configuration as soon as possible after the end of the second time window.

[0150] Optionally, when the number of first time windows is N, the number of second time windows is M, and each of the second time windows covers at least one first time window among the N first time windows, N is a positive integer, and M is a positive integer less than or equal to N.

[0151] In one implementation, multiple first time windows may correspond to one second time window. Taking the first time window as a measurement interval and the second time window as a DRX configuration pause window as an example, one measurement interval configuration includes multiple measurement intervals, and the multiple measurement intervals correspond to one DRX configuration pause window, and the DRX configuration pause window covers all measurement intervals based on the measurement interval configuration, such as Figure 5a It should be noted that this implementation is applicable to the case where the period of the non-transmittable time window (ie, the first time window) is short or the interval between adjacent non-transmittable time windows is small.

[0152] In another embodiment, multiple first time windows may correspond to multiple second time windows. When there are multiple non-transmittable time windows (i.e., first time windows), each or each group of non-transmittable time windows corresponds to a second time window, and these non-transmittable time windows may be periodic or non-periodic, and these non-transmittable time windows may be of equal length or unequal length. Taking the first time window as a measurement interval and the second time window as a DRX configuration pause window as an example, each measurement interval of a measurement interval configuration corresponds to a DRX configuration pause window, such as Figure 5b It should be noted that this implementation is applicable to the case where the period of occurrence of the non-transmittable time window is relatively long or the interval between adjacent non-transmittable time windows is relatively large.

[0153] In some optional embodiments, the DRX configuration may suspend operation from the first non-transmission time window of the non-transmission time window configuration (e.g., the measurement interval configuration) until the suspension is canceled (i.e., continues to operate) at the end of the last non-transmission time window of the non-transmission time window configuration.

[0154] Optionally, the first operation includes suspending or stopping applying part or all of the DRX configuration in the second time window, and the method further includes:

[0155] The terminal receives a first activation instruction from a network side device;

[0156] The first activation instruction is used to instruct activation of the DRX configuration.

[0157] In this embodiment, when the first operation includes suspending or stopping the application of part or all of the DRX configuration in the second time window, if the network side device determines that the DRX configuration needs to be applied, it can send a DRX configuration activation command (i.e., the above-mentioned first activation instruction), and the terminal can stop suspending the application of part or all of the DRX configuration or continue to apply the DRX configuration based on the above-mentioned DRX configuration activation command, thereby improving the flexibility of DRX control.

[0158] See also Figure 6 , Figure 6 is a flow chart of a discontinuous reception control method provided by an embodiment of the present application, which can be executed by a network side device, such as Figure 6 As shown, the following steps are included:

[0159] Step 601: The network side device determines the activation time of the terminal according to the relative position relationship between the first time window and the first activation time; wherein the first time window is a time window in which data cannot be transmitted, and the first activation time is the activation time of the terminal determined according to the DRX configuration;

[0160] Step 602: The network side device schedules the terminal according to the activation time of the terminal.

[0161] The relative position relationship between the first time window and the first activation time can be used to indicate whether the first time window overlaps with the first activation time. Exemplarily, when there is no overlap between the first time window and the first activation time, the network side device can schedule the terminal based on the first activation time; when there is an overlap between the first time window and the first activation time, the network side device can adjust the activation time of the terminal and schedule the terminal based on the adjusted activation time.

[0162] Optionally, the network side device determines the activation time of the terminal according to a relative position relationship between the first time window and the first activation time, including:

[0163] In a case where there is an overlap between the first time window and the first activation time, the network side device determines the activation time of the terminal according to the first information;

[0164] The first information includes at least one of the following: the first time window, the DRX configuration, and the second information;

[0165] The second information is used by the terminal to adjust the activation time of the terminal when there is an overlap between the first time window and the first activation time.

[0166] In this embodiment, in the case where there is an overlap between the first time window and the first activation time, the network side device can determine the activation time of the terminal based on the first information. Exemplarily, the network side device can determine the activation time of the terminal based on the running time period of the DRX timer configured by the DRX and the first time window. For example, the running time period of the DRX timer configured by the DRX (i.e., the first activation time) is postponed to the time period after the first time window as the activation time of the terminal; or, the running time period of the DRX timer configured by the DRX (i.e., the first time period) is extended to the time period after the second time length as the activation time of the terminal, and the second time length is the length of the overlapping part between the first time window and the running time period of the DRX timer configured by the DRX; or, the network side device can determine the activation time of the terminal based on the second information and the DRX configuration. For example, if the second information includes a second initial value, the initial value of the DRX timer configured by the DRX can be adjusted to the second initial value, and the running time period of the DRX timer is determined as the activation time of the terminal.

[0167] It is understandable that the network-side device may adjust the activation time of the terminal in the same manner as the terminal, so as to ensure consistency in the understanding of the activation time of the terminal by the network-side device and the terminal.

[0168] Optionally, the method further comprises:

[0169] The network side device sends second information to the terminal;

[0170] The second information is used to configure the terminal to adjust the activation time of the terminal when there is an overlap between the first time window and the first activation time.

[0171] In some optional embodiments, the second information may be provided in a corresponding DRX configuration, or may be provided in a non-transmittable time window related configuration (eg, MG configuration).

[0172] Optionally, the first activation time is an activation time determined according to a DRX timer, and the second information includes at least one of the following: a second initial value, a first offset value;

[0173] The second initial value is used to adjust the initial value of the DRX timer, and the first offset value is used to adjust the initial value of the DRX timer.

[0174] Optionally, the method further comprises:

[0175] The network side device sends a first activation instruction to the terminal;
