The base station is not limited to a specific technical term, and it should be noted that only a base station in an NR system is taken as an example in the embodiments of the present application, but the specific type of the base station is not limited.

[0046] The time matching method provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings and some embodiments and application scenarios.

[0047] XR(eXtended Reality) services include AR(Augmented Reality) services, VR(Vitual Reality) services, and MR(Mixed AR and VR) services. Currently, popular XR services use H.264 encoding technology to compress image data, save traffic, and ensure image quality.

[0048] The existing H.264 technology encodes image data into three types of image frames:

[0049] I frame (Intra-coded picture), a complete image frame, can be generated and presented without relying on other frames;

[0050] P frame (Predicted picture), only contains image change information relative to the previous frame, the receiving party needs to combine the previous frame to generate the current frame, and complete the display on the receiving terminal;

[0051] B frame (Bidirectional predicted picture), used to indicate the change information of the current frame relative to the previous frame and the next frame. The receiving party needs to combine the previous frame and the next frame to generate the current frame.

[0052] The above-mentioned previous frame and next frame refer to the order of frame presentation time or image acquisition time of the source end. The actual sending and receiving time may be adjusted according to the image decoding time of the receiving party, for example, the sender can send according to the image frame decoding time sequence of the receiving party.

[0053] 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 lower (i.e. the frame data volume is the largest), the compression degree of P frame is moderate (i.e. the frame data volume is moderate), and the compression degree of B frame is the highest (i.e. the frame data volume is the smallest).

[0054] XR image has two transmission modes, one is based on frame slice combination, and the other is based on frame set (group of picture, GoP).

[0055] The transmission mode based on slice combination: a data frame is cut into multiple data blocks, and then the cut blocks of multiple image frames are dispersed and combined into multiple data blocks for transmission, so as to achieve the purpose of smooth XR service data flow. This method greatly reduces the flow fluctuation caused by the difference in I / P / B frame data volume, but due to the cross transmission between image frames, the transmission delay of image frames is obviously increased;

[0056] The transmission mode based on frame set (see Figure 2 , wherein, Figure 2Fig. 1 is a schematic diagram of XR image frame transmission based on frame set GoP: According to the periodicity of the video stream, the video frames are divided into video frame combinations according to the period of I frames, one I frame and all P and B frames before the next I frame, which constitute a frame combination. Image frames are transmitted and played at the receiving end according to the frame period, and the time interval between the arrival times of adjacent image frames is a frame period. The transmission method based on frame set avoids mixed transmission between image frames, so that the generated image frames are transmitted in time. Due to the different compression degrees of I, P and B frames, the frame data rate fluctuates.

[0057] The current measurement and reporting has periodic measurement and reporting, semi-static periodic measurement and reporting, and measurement and reporting triggered by the serving base station on demand. Similarly, there are three ways to send Sounding Reference Signal (SRS): periodic transmission, semi-static periodic transmission and on-demand transmission. Scheduling request (SR) uses periodically configured Physical Uplink Control Channel (PUCCH) resources for transmission.

[0058] The arrival time period granularity of XR video frames (8.33, 16.67, 33.33 ms) does not match the configuration granularity of the transmission period and offset of Channel state information reference signal (CSI-RS) (number of slots or symbols), the reporting period and offset of Channel state information (CSI) (number of slots or symbols), the transmission period and offset of SRS (number of slots or symbols) and the PUCCH period and offset of SR (number of slots or symbols), which leads to:

[0059] The initial CSI-RS resource and CSI reporting that adapt to the image frame arrival time and the SRS resource become unsuitable for the image frame arrival time due to the accumulation of time offset;

[0060] The initial periodic SR resource that adapts to the image frame arrival time becomes unsuitable for the uplink image frame arrival time due to the accumulation of time offset;

[0061] This mismatch will cause the timeliness of CSI / SRS measurement and CSI reporting to deteriorate, and the SR cannot be sent in time, further leading to a decrease in spectral efficiency or an increase in transmission delay of data transmission.

[0062] Assuming that the periodicity of CSI-RS, CSI reporting, PUCCH-SR and SRS can be extended, the periodicity and offset of any integer time slots can be configured. Figure 3 A diagram of the cumulative offset of CSI-RS and CSI reporting relative to the arrival time of a video frame within one I-frame period, Figure 4 A diagram of the cumulative offset of PUCCH-SR relative to the arrival time of a video frame within one I-frame period, Figure 5 A diagram of the cumulative offset of SRS relative to the arrival time of a video frame within one I-frame period. The periodicity of CSI-RS, CSI reporting, PUCCH-SR and SRS is taken as an example of 16.5ms (33 slots, corresponding to SCS 30KHz). Within one I-frame period, the cumulative offset time reaches 1.84ms (11*(16.67-16.5)ms). After a number of I-frame periods, the cumulative offset will make the configured CSI-RS, CSI reporting, PUCCH-SR and SRS window and the arrival time of the image frame cumulatively offset, resulting in a decrease in spectral efficiency and an increase in delay in data transmission, including:

[0063] The time granularity of the periodicity and offset of periodic CSI-RS and periodic CSI reporting does not match the frame arrival time granularity of downlink XR services, causing the cumulative offset between CSI-RS transmission and / or CSI reporting and the arrival time of XR service image frames, resulting in untimely CSI measurement or transmission of CSI reports, causing the base station to only schedule based on outdated CSI, reducing the spectral efficiency of downlink frame data transmission;

[0064] The time granularity of the periodicity and offset of periodic uplink SRS does not match the image frame data arrival time granularity, causing the cumulative offset between SRS transmission and the arrival time of XR service image frames, causing the base station to only schedule uplink data based on outdated uplink channel measurements after a period of time, reducing the efficiency of uplink image frame data transmission;

[0065] The time granularity of the periodicity and offset of periodic PUCCH-SR signals does not match the image frame arrival time granularity of XR services, causing the cumulative offset between PUCCH-SR transmission and the arrival time of XR service image frames, resulting in the XR terminal being unable to transmit SR in a timely manner, increasing the transmission delay of the above image frame data.

[0066] To solve the above problems, the embodiments of the present application provide a time matching method. Figure 6 One of the flowcharts of the time matching method provided by the embodiments of the present application includes:

[0067] Step 600, the terminal matches a first time window with a data transmission window of a target service based on the re-matching configuration of a first periodic template; or,

[0068] The terminal adjusts the first time window according to the time offset value of the first time window and the target window, so as to match the first time window with the data transmission window of the target service, wherein the target window is a time window determined according to the data transmission window of the target service.

[0069] In some optional embodiments, the terminal re-matches each first periodic pattern with the arrival time or sending time of an image frame based on the configuration manner of periodic pattern re-matching.

[0070] The first periodic pattern includes at least one first time window, and each first time window corresponds to a data transmission window of a target service.

[0071] The first time window includes at least one of a first periodic signal transmission time window and a periodic information reporting time window.

[0072] Optionally, the first periodic signal transmission time window is a time domain window of a periodic signal resource, which can be any one of a start sending time, a termination sending time or a continuous sending time of the periodic signal, or can be any one of a start receiving time, a termination receiving time or a continuous receiving time of the periodic signal.

[0073] The periodic information reporting time window is a time window of periodic information sending, which can be any one of a start sending time, a termination sending time or a continuous sending time of the periodic information.

[0074] Optionally, the periodic signal can be a CSI-RS, a PUCCH-SR or an SRS; and the periodic information can be a CSI report.

[0075] Optionally, the data transmission window of the target service is an arrival time of XR service image frame data.

[0076] For example, the n-th CSI-RS receiving time window, the n-th CSI reporting time window, the n-th PUCCH-SR sending time window and the SRS sending time window in each first periodic pattern correspond to an arrival time of an image frame data, and n is a positive integer greater than or equal to 1.

[0077] Optionally, the first periodic signal transmission time window and the periodic information reporting time window in each first periodic pattern are determined according to a preconfigured period and offset.

[0078] Optionally, the CSI-RS receiving time window, the CSI reporting time window, the PUCCH-SR sending time window and the SRS sending time window in each first periodic pattern are determined according to a preconfigured period and offset.

[0079] In some optional embodiments, the terminal matches the first time window with the data transmission window of the target service based on the re-matching configuration mode of automatic correction.

[0080] Optionally, the network-side device configures a desired period and offset (i.e., target period and offset) according to the arrival or sending time of the image frame, and the terminal ensures that the CSI-RS receiving time window, the CSI reporting time window, the SRS sending time window, and the PUCCH-SR sending time window always match the XR image frame arrival time according to the desired period and offset. It can be understood that the terminal automatically corrects according to the time offset values of the CSI-RS receiving time window, the CSI reporting time window, the SRS sending time window, and the PUCCH-SR sending time window and the respective target windows, so that the subsequent CSI-RS receiving time window, the CSI reporting time window, the SRS sending time window, and the PUCCH-SR sending time window match the XR image frame to be sent / received.

[0081] That is, the terminal adjusts the first time window according to the time offset value of the first time window and the target window, so that the first time window matches the data transmission window of the target service, wherein the target window is a time window determined according to the data transmission window of the target service.

[0082] It should be noted that the matching in the embodiments of the present application means that the first periodic signal transmission time window and the periodic information reporting time window appear at the desired time, so as to ensure the uplink and downlink adaptive performance, improve the transmission efficiency, and reduce the transmission delay.

[0083] The first periodic signal transmission time window and the periodic information reporting time window appear at the desired time, including:

[0084] The CSI-RS receiving time window and the CSI reporting time window appear at the desired time, so that the CSI can be measured and reported in time, and the downlink adaptive performance is ensured;

[0085] The SRS sending time window and the PUCCH-SR sending time window appear at the desired time, so that the uplink channel can be measured in time, the SR can be transmitted in time, the uplink adaptive performance is improved, and the uplink transmission delay is reduced.

[0086] Optionally, adjusting the first time window means adjusting the period and offset of the periodic signal.

[0087] In the embodiments of the present application, the periodic signal transmission time window or the periodic information reporting time window is matched with the data transmission window of the target service through the re-matching configuration mode based on the periodic template or the re-matching configuration mode of automatic correction, which can ensure the uplink and downlink adaptive performance, improve the transmission efficiency, and reduce the transmission delay.

[0088] Optionally, the terminal re-matches each first time window in the first periodic template with a data transmission window of a target service, so that a difference between a position where each first time window occurs and a target position is less than a first threshold X;

[0089] re-matches each first time window in the first periodic template with a data transmission window of a target service, so that a difference between a position where each first time window occurs and a target position is less than a first threshold X;

[0090] wherein the first threshold X is a maximum relative offset of the first time window in the first periodic template from the target position.

[0091] wherein the target position matches a data transmission window of a corresponding target service.

[0092] A first periodic template contains an integer number of time windows (e.g. CSI-RS reception time windows, CSI reporting time windows, PUCCH-SR transmission time windows or SRS transmission time windows), and the time windows in each template are periodic, and the occurrence of the template is also periodic.

[0093] Each first time window corresponds to a data transmission window of a target service. Optionally, taking a target service data XR service image frame as an example, the time length of a template is exactly equal to N (a positive integer) target service data transmission (image frame) periods. Each window in the template corresponds to an image frame. If the first window occurs exactly at a desired position (referred to as a target position, which matches the arrival time of the corresponding image frame), the relative cumulative offset of the last window in the template from the target position due to the mismatch of time granularity is X = (N-1)*(picture frame period - window period). Each window in the template is re-matched with an image frame, and the maximum value of the difference between the position where the window occurs and the target position is X, which does not continue to increase with time; if N is small enough, X does not exceed the maximum acceptable value.

[0094] Figure 7 A re-matching mode of CSI-RS reception time windows and CSI reporting time windows based on a periodic template (SCS 30KHz, frame period = 50 / 3ms, CSI-RS period = 16.5ms, i.e. 33 slots, CSI report period = 33 slots) is shown, and the first CSI-RS reception time window or CSI reporting time window in the template occurs at a target position, and the maximum cumulative offset between the position where the window occurs and the corresponding target position is 0.33ms. Through this periodic template re-matching configuration mode, the maximum offset of the CSI-RS reception time window or CSI reporting time window from the desired window occurrence time is controlled below a given value.

[0095] Optionally, the period and offset of the first periodic template are configured to the terminal by the network-side device through an RRC message.

[0096] For example, the network-side device needs to configure the period and offset of the CSI-RS template to the terminal through an RRC message, so that the position of each CSI-RS receiving time window in the first periodic template deviates from the target CSI-RS receiving time window by less than a threshold. The PUCCH-SR template and the SRS template are configured similarly, and examples are not given here.

[0097] Optionally, the adjusting the first time window according to the time offset value of the first time window from the target window comprises:

[0098] In the case that the time offset value of the first time window from the target window exceeds a first preset threshold, adjusting the period and offset of the first time window; or,

[0099] Every preset time, adjusting the period and offset of the first time window according to the time offset value of the first time window from the target window.

[0100] The embodiments of the present application give the trigger condition for adjusting the first time window.

[0101] In an implementation, in the case that the time offset value of the first time window from the target window exceeds a first preset threshold, the terminal adjusts the period and offset of the first time window.

[0102] Optionally, whenever the time difference between the CSI-RS, the CSI report, the SRS and the PUCCH-SR and the target image frame reaches the respective offset threshold, the UE adjusts the period and offset configuration of the CSI-RS, the CSI report, the SRS and the PUCCH-SR.

[0103] Optionally, the network side device configures a period and offset (CSI-RS window, CSI reporting window, PUCCH-SR transmission window or SRS transmission window) in absolute time of the 5G system, which is used to determine the time when the target window appears, serves the corresponding image frame, and matches the data transmission requirement of the corresponding image frame. Since the 5G system time is fine enough, it can be assumed that the accumulated offset between the target window and the served image frame can be ignored. The network side device also provides a period and offset configuration of an effective window (CSI-RS receiving time window, CSI reporting time window, PUCCH-SR transmission time window or SRS transmission time window) for the terminal or the network side device to determine the actual appearance time of the effective window and perform transmission, measurement and reporting operations. The period and offset are configured in the time granularity (slot, OFDM symbol, etc.) of the 5G-RAN, resulting in an offset between the appearance time of the effective window and the appearance time of the target window that cannot be ignored and accumulates over time.

[0104] When the lag offset of the effective window relative to the target window exceeds a threshold, the terminal or the network side device compensates the position of the subsequent effective window by an offset, reducing the offset of the effective window relative to the target window to an acceptable range. When the lead offset of the effective window relative to the target window exceeds another threshold, the terminal or the network side device compensates the position of the subsequent effective window by an offset, reducing the offset of the effective window relative to the target window to an acceptable range. The above two thresholds can be modeled as the same threshold, for example, when the absolute value of the accumulated offset of the effective window and the target window exceeds a preset threshold, the terminal or the network side device compensates the position of the subsequent effective window by an offset, reducing the offset of the effective window relative to the target window to an acceptable range.

[0105] In another implementation, every preset time, the terminal adjusts the period and offset of the first time window according to the time offset value of the first time window and the target window.

[0106] Optionally, every specified time, the terminal adjusts the period and offset configuration of the CSI-RS, the CSI report, the SRS and the PUCCH-SR.

[0107] Optionally, before adjusting the first time window according to the time offset value of the first time window and the target window, the method further comprises:

[0108] Receiving the PDCCH command or the MAC CE sent by the network side device, wherein the PDCCH command or the MAC CE is used to instruct the terminal to adjust the first time window.

[0109] It can be understood that the terminal receives a physical downlink control channel (PDCCH) command sent by the network side device, and adjusts the first time window according to the indication of the command.

[0110] Optionally, the terminal receives a media access control control element (MAC CE) sent by the network side device, and adjusts the first time window according to the indication of the MAC CE.

[0111] Optionally, the adjusting of the first time window according to the time offset value of the first time window and the target window comprises:

[0112] In a case where the time offset value of the first time window and the target window exceeds a second preset threshold, adjusting the period and offset of the first time window according to a first target adjustment amount;

[0113] The first target adjustment amount is indicated by the network side device through a first dynamic signaling, and the first dynamic signaling comprises downlink control information (DCI), a media access control control element (MAC CE), or radio resource control (RRC) signaling.

[0114] According to the time difference between the position of the target window and the effective window (i.e., the actual CSI-RS receiving actual window, the CSI reporting time window, the PUCCH-SR sending time window, or the SRS sending time window), the terminal receives a dynamic instruction sent by the network side device, and adjusts the position of the effective window.

[0115] The dynamic instruction can be sent by DCI, MAC CE, or RRC signaling, and the dynamic instruction carries an offset amount of forward or backward adjustment of the effective window of the UE, i.e., a first target adjustment amount. The DCI can be identified by a pre-configured RNTI.

[0116] Optionally, before the adjusting of the first time window according to the time offset value of the first time window and the target window, the method further comprises:

[0117] Receiving the first dynamic signaling sent by the network side device, the first dynamic signaling further carrying a first effective time;

[0118] The adjusting of the period and offset of the first time window according to the first target adjustment amount comprises:

[0120] Optionally, the received dynamic instruction can take effect immediately or at a given time point, for example, at a certain position of the next radio frame, at which time the first dynamic signaling carries not only the target adjustment amount but also a first effective time.

[0121] The terminal adjusts the period and offset of the first time window according to the first target adjustment amount at the first effective time.

[0122] Optionally, the first time window matches a data transmission window of a target service, including:

[0123] The first time window is within a first preset time range before a data transmission window of a corresponding target service. The first preset time range is determined according to a time offset relative to the data transmission window of the target service.

[0124] It can be understood that the first time window within the first preset time range before the data transmission window of the corresponding target service can enable the CSI to be measured and reported in time, ensure the downlink adaptive performance, or enable the uplink channel to be measured in time, the SR to be transmitted in time, improve the performance of the uplink adaptive, and reduce the uplink transmission delay.

[0125] Optionally, the first periodic signal transmission time window includes at least one of the following: a channel state information reference signal (CSI-RS) reception time window, a physical uplink control channel scheduling request (PUCCH-SR) transmission time window, and a sounding reference signal (SRS) transmission time window.

[0126] The periodic information reporting time window includes a channel state information (CSI) report transmission time window.

[0127] Optionally, the first time window matches a data transmission window of a target service, including at least one of the following:

[0128] The CSI-RS reception time window is within a first time range before a corresponding downlink data reception time window.

[0129] The PUCCH-SR transmission time window is within a second time range before a corresponding uplink data transmission time window.

[0130] The SRS transmission time window is within a third time range before a corresponding uplink data transmission time window.

[0131] The CSI report transmission time window is within a fourth time range before the downlink data reception time window.

[0132] The first time range is determined by at least one of a minimum time offset and a maximum time offset relative to the CSI-RS reception time window.

[0133] The second time range is determined by at least one of a minimum time offset and a maximum time offset relative to the PUCCH-SR transmission time window.

[0134] The third time range is determined by at least one of a minimum time offset and a maximum time offset relative to the SRS transmission time window.

[0135] The fourth time range is determined by at least one of a minimum time offset and a maximum time offset relative to the CSI report transmission time window.

[0136] Optionally, the target service is an extended reality (XR) service, wherein the XR service includes an augmented reality (AR) service, a virtual reality (VR) service, or a mixed reality service.

[0137] The data transmission window of the target service corresponds to an arrival time of an image frame of the XR service.

[0138] In the embodiments of the present application, by means of the configuration mode based on periodic template rematching or the configuration mode of automatic correction rematching, the periodic signal transmission time window or the periodic information reporting time window is matched with the arrival time of the image frame of the XR service, which can ensure the uplink and downlink adaptive performance, improve the XR service transmission efficiency, and reduce the XR service transmission delay.

[0139] Figure 8 As shown in FIG. 2, the method includes the following steps. Figure 8

[0140] In step 800, the network side device matches a second time window with a data transmission window of a target service based on rematching configuration of a second periodic template.

[0141] In step 800, the network side device matches a second time window with a data transmission window of a target service based on rematching configuration of a second periodic template.

[0142] It can be understood that, consistent with the terminal side, the network side device also needs to match the second time window with the data transmission window of the target service.

[0143] The second time window includes at least one of the following: a second periodic signal transmission time window, a periodic information receiving time window.

[0144] ​It should be noted that the second-cycle signal transmission time window is for the network-side equipment and is related to the first-cycle signal transmission time window. For example, if the first-cycle signal transmission time window is the CSI-RS reception time window, then the second-cycle signal transmission time window is the CSI-RS transmission time window.

[0145] In some alternative implementations, the network-side device is configured to rematch each second periodic pattern with the arrival or transmission time of the image frame based on a periodic pattern rematch configuration.

[0146] The second periodic template includes at least one second time window, and each second time window corresponds to a data transmission window of a target service.

[0147] Optionally, the second periodic signal transmission time window is a time-domain window of the periodic signal resource, which can refer to any point in time among the start time, end time, or continuous transmission time of the periodic signal, or any point in time among the start time, end time, or continuous reception time of the periodic signal.

[0148] The periodic information reception time window is the time window for receiving periodic information, which can be the start time of reception, the end time of reception, or any point in time during continuous reception of periodic information.

[0149] Optionally, the periodic signal can be CSI-RS, PUCCH-SR, or SRS; the periodic information can be a CSI report. The data transmission window of the target service is the arrival time of the XR service image frame data.

[0150] For example, the nth CSI-RS transmission time window, the nth CSI report reception time window, the nth PUCCH-SR reception time window, and the SRS reception time window within each second periodic template correspond to the arrival time of an image frame data, where n is a positive integer greater than or equal to 1.

[0151] Optionally, the second periodic signal transmission time window and the periodic information reception time window within each second periodic template are determined according to a pre-configured period and offset.

[0152] Optionally, the CSI-RS transmission time window, CSI report reception time window, PUCCH-SR reception time window, and SRS reception time window within each second periodic template are determined according to a pre-configured period and offset.

[0153] In some alternative implementations, the network-side device uses an auto-correction rematch configuration to match the second time window with the data transmission window of the target service.

[0154] Optionally, the network-side device configures a desired period and offset (i.e., target period and offset) according to the arrival or sending time of the image frame, and then ensures that the CSI-RS sending time window, the CSI report receiving time window, the SRS receiving time window, and the PUCCH-SR receiving time window always match the XR image frame arrival time according to the desired period and offset. It can be understood that the network-side device automatically corrects the time offset value of the CSI-RS sending time window, the CSI report receiving time window, the SRS receiving time window, and the PUCCH-SR receiving time window from the respective target window, so that the subsequent CSI-RS sending time window, the CSI report receiving time window, the SRS receiving time window, and the PUCCH-SR receiving time window match the XR image frame to be sent / received.

[0155] That is, the network-side device adjusts the second time window according to the time offset value of the second time window from the target window, so that the second time window matches the data transmission window of the target service, wherein the target window is a time window determined according to the data transmission window of the target service.

[0156] It should be noted that the matching in the embodiments of the present application means that the second periodic signal transmission time window and the periodic information receiving time window appear at the expected time, so as to ensure the uplink and downlink adaptive performance, improve the transmission efficiency, and reduce the transmission delay.

[0157] The second periodic signal transmission time window and the periodic information receiving time window appear at the expected time, including:

[0158] The CSI-RS sending time window and the CSI report receiving time window appear at the expected time, so that the CSI can be measured and reported in time, and the downlink adaptive performance is ensured;

[0159] The SRS receiving time window and the PUCCH-SR receiving time window appear at the expected time, so that the uplink channel can be measured in time, the SR can be transmitted in time, the uplink adaptive performance is improved, and the uplink transmission delay is reduced.

[0160] In the embodiments of the present application, by the configuration mode of re-matching based on the periodic template or the configuration mode of automatic correction re-matching, the periodic signal transmission time window or the periodic information receiving time window matches the data transmission window of the target service, which can ensure the uplink and downlink adaptive performance, improve the transmission efficiency, and reduce the transmission delay.

[0161] Optionally, the network-side device matches the second time window with the data transmission window of the target service based on the re-matching configuration of the second periodic template, including:

[0162] re-matching each second time window in the second periodic template with a data transmission window of a target service, so that a difference between a position where each second time window appears and a target position is less than a second threshold Y;

[0163] wherein the second threshold Y is a maximum relative offset of a second time window in the second periodic template from the target position;

[0164] wherein the target position matches a data transmission window of a corresponding target service.

[0165] A second periodic template contains an integer number of time windows (e.g. CSI-RS transmission time windows, CSI reporting reception time windows, SRS reception time windows and PUCCH-SR reception time windows), and the time windows in each template present periodicity, and the appearance of the template is also periodic.

[0166] Each of the second time windows corresponds to a data transmission window of a target service. Optionally, taking data of a target service as an example of XR service image frame. The time length of a template is exactly equal to M (positive integer) target service data transmission (image frame) periods. Each window in the template corresponds to an image frame. If the first window appears exactly at the desired position (referred to as the target position, the target position matches the arrival time of the corresponding image frame), the relative cumulative offset of the last window in the template from the target position due to the mismatch of time granularity is Y = (M-1)*(picture frame period-window period). Each window in the template is re-matched with the image frame, and the maximum difference between the position where the window appears and the target position is Y, which does not continue to increase with time; if M is small enough, Y does not exceed the maximum acceptable value.

[0167] Optionally, further comprising:

[0168] determining a period and offset configuration of a first periodic template;

[0169] sending the period and offset configuration of the first periodic template to a terminal through an RRC message;

[0170] wherein the first periodic template includes at least one first time window, and each of the first time windows corresponds to a data transmission window of a target service.

[0171] For example, a network side device determines a period and offset configuration of a first periodic template, and sends the period and offset configuration to a terminal through an RRC message, so that the position of each CSI-RS reception time window in the first periodic template deviates from a target CSI-RS reception time window by less than a threshold. PUCCH-SR template and SRS template are configured similarly, and examples are not given here.

[0172] Optionally, the adjusting the second time window according to the time offset value of the second time window and the target window comprises:

[0173] In a case where the time offset value of the second time window and the target window exceeds a first preset threshold, adjusting the period and offset of the second time window; or,

[0174] Every preset time, adjusting the period and offset of the second time window according to the time offset value of the second time window and the target window.

[0175] The embodiment of the present application gives a trigger condition for adjusting the second time window.

[0176] In an implementation, in a case where the time offset value of the second time window and the target window exceeds a first preset threshold, the network side device adjusts the period and offset of the second time window.

[0177] Optionally, whenever the time difference between the CSI-RS, the CSI report, the SRS and the PUCCH-SR and the target image frame reaches the respective offset threshold, the network side device adjusts the period and offset configuration of the CSI-RS, the CSI report, the SRS and the PUCCH-SR.

[0178] Optionally, the network side device configures a period and offset (CSI-RS window, CSI report window, PUCCH-SR transmission window or SRS transmission window) whose period and offset can be configured according to the absolute time of the 5G system, for determining the time when the target window appears, serving the corresponding image frame, matching the data transmission requirement of the corresponding image frame, since the 5G system time is fine enough, it can be assumed that the offset accumulation between the target window and the served image frame can be ignored. The network side device also provides a period and offset configuration of an effective window (CSI-RS receiving time window, CSI report time window, PUCCH-SR transmission time window or SRS transmission time window) for determining the actual appearance time of the effective window, performing the operation of sending, measuring and receiving the terminal report, whose period and offset are configured by using the time granularity (slot, OFDM symbol, etc.) of the 5G wireless access network (5G-RAN), resulting in that the time when the effective window appears has an offset from the time when the target window appears, which cannot be ignored and accumulates over time.

[0179] When the lagging offset of the valid window relative to the target window exceeds a threshold, the terminal or the network side device compensates the position of the subsequent valid window by an offset, reducing the offset of the valid window relative to the target window to an acceptable range. When the leading offset of the valid window relative to the target window exceeds another threshold, the terminal or the network side device compensates the position of the subsequent valid window by an offset, reducing the offset of the valid window relative to the target window to an acceptable range. The above two thresholds can be modeled as the same threshold, for example, when the absolute value of the cumulative offset of the valid window and the target window exceeds a preset threshold, the terminal or the network side device compensates the position of the subsequent valid window by an offset, reducing the offset of the valid window relative to the target window to an acceptable range.

[0180] In another implementation, at a preset time, the network side device adjusts the period and offset of the second time window according to the time offset value of the second time window relative to the target window.

[0181] Optionally, at a specified time, the network side device adjusts the period and offset configuration of the CSI-RS, the CSI report, the SRS and the PUCCH-SR.

[0182] Optionally, the method further comprises:

[0183] sending a PDCCH command or a MAC CE to the terminal, the PDCCH command or the MAC CE being used to instruct the terminal to adjust the first time window.

[0184] sending a PDCCH command or a MAC CE to the terminal, the PDCCH command or the MAC CE being used to instruct the terminal to adjust the first time window.

[0185] Optionally, the adjusting the second time window according to the time offset value of the second time window relative to the target window comprises:

[0186] when the time offset value of the second time window relative to the target window exceeds a second preset threshold, adjusting the period and offset of the second time window according to a second target adjustment amount; or

[0188] wherein the second target adjustment amount is determined based on the time offset value of the second time window relative to the target window.

[0189] It can be understood that the network side device adjusts the period and offset of the second time window according to the second target adjustment amount in the case that the time offset value of the second time window and the target window exceeds the second preset threshold, or adjusts the period and offset of the second time window according to the second target adjustment amount at the second effective time.

[0195] The second time window is within a second preset time range before the data transmission window of the corresponding target service. The second preset time range is determined according to the time offset relative to the data transmission window of the target service.

[0196] It can be understood that the second time window is within a second preset time range before the data transmission window of the corresponding target service, which can enable the CSI to be measured and reported in time, ensure the downlink adaptive performance, or enable the uplink channel to be measured in time, the SR to be transmitted in time, improve the performance of uplink adaptive, and reduce the uplink transmission delay.

[0197] Optionally, the second periodic signal transmission time window includes at least one of the following: a channel state information reference signal (CSI-RS) transmission time window, a physical uplink control channel scheduling request (PUCCH-SR) reception time window, and a sounding reference signal (SRS) reception time window.
