The time matching method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios in conjunction with the accompanying drawings.

XR (eXtended Reality) business includes AR (Augmented Reality) business, VR (Vitual Reality) business and MR (Mixed AR and VR) business. Currently, popular XR services use H.264 encoding technology to achieve image data compression, saving traffic and ensuring image quality. Existing H.264 technology encodes image data into three types of image frames:

I frame (Intra-coded picture) is a complete image frame that can be generated and presented independently of other frames;

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

B frame (Bidirectional predicted picture), 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.

The preceding frames and subsequent frames are sorted according to the frame presentation time or the image acquisition time of the source. The actual sending and receiving time may be adjusted according to the image decoding time of the receiver. For example, the sender can Frames are sent in decoding time order.

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 amount of frame data is the largest), the degree of compression of P frame is moderate (that is, the amount of frame data is moderate), and the degree of compression of B frame is the highest (that is, the amount of frame data is the smallest).

There are two transmission methods for XR images, the transmission method based on frame slice combination and the transmission method based on group of pitcture (GoP).

Slicing-based transmission combination transmission method: cut a data frame into multiple data blocks, and then disperse and combine the slices of multiple image frames into multiple data blocks for transmission, so as to achieve the purpose of smoothing the flow of an XR business data flow. This method greatly reduces the traffic fluctuation caused by the difference in the data volume of I/P/B frames, but due to the cross transmission between graphics frames, the transmission delay of image frames is obviously increased;

Transmission mode based on frame set (see Figure 2, wherein Figure 2 is a schematic diagram of XR image frame transmission based on frame set GoP): according to the periodicity of the video stream, the video frame is divided into video frame combinations according to the period of the I frame, An I frame and all the P frames and B frames before the next I frame constitute a frame combination. Image frames are transmitted and played at the receiver according to the frame period, and the time interval between the frame arrival times of adjacent image frames is a frame period. The frame set-based transmission method avoids mixed transmission between image frames, so that the generated image frames can be transmitted in time. The frame data rate fluctuates due to the different degrees of compression between I, P, and B frames.

The current measurement and report includes periodic measurement and report, semi-static periodic measurement and report, and measurement and report triggered by the serving base station on demand. Similarly, there are three ways to send the Sounding Reference Signal (SRS): periodic transmission, semi-static periodic transmission and on-demand transmission. A scheduling request (Scheduling request, SR) is transmitted using periodically configured physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources.

The granularity of the arrival time period of the XR video frame (8.33, 16.67, 33.33ms) and the configuration granularity of the transmission period and offset of the channel state information reference signal (Channel state information reference signal, CSI-RS) (number of slots or symbols number), channel state information (Channel state information, CSI) reporting cycle and offset configuration granularity (number of slots or symbols), SRS transmission cycle and offset configuration granularity (number of slots or symbols) And the situation that the PUCCH period of SR and the offset configuration granularity (number of slots or symbols) do not match, resulting in:

The CSI-RS resources and CSI reporting and SRS resources that initially basically adapt to the arrival time of the image frame become incompatible with the arrival time of the image frame due to the accumulation of time offsets;

The periodic SR resources that initially adapt to the arrival time of the image frame become unsuitable for the arrival time of the uplink image frame due to the accumulation of time offset;

This mismatch will lead to poor timeliness of CSI/SRS measurement and CSI reporting, and SR cannot be sent in time, further resulting in reduced spectral efficiency of data transmission or increased transmission delay.

Assuming that the periods of CSI-RS, CSI report, PUCCH-SR and SRS can be extended, the period and offset of any integer time slot can be configured. Figure 3 is a schematic diagram of the cumulative offset of CSI-RS and CSI reports relative to the video frame arrival time within an I frame period, and Figure 4 is the cumulative offset of the PUCCH-SR relative to the video frame arrival time within an I frame period Figure 5 is a schematic diagram of the cumulative offset of the SRS relative to the video frame arrival time within one I frame period. The period of CSI-RS, CSI report, PUCCH-SR and SRS is 16.5ms (33slots, corresponding to SCS 30KHz) as an example. In one I frame period, the cumulative offset time reaches 1.84ms (11*(16.67-16.5)ms). After several I frame periods, the inner product offset will make the configured CSI-RS, CSI report, PUCCH-SR and The cumulative offset between the SRS window and the arrival time of the image frame is very large, resulting in a decrease in the spectral efficiency of data transmission and an increase in delay, including:

The period and offset time granularity of periodic CSI-RS and periodic CSI reports do not match the frame arrival time granularity of the downlink XR service, resulting in a gap between CSI-RS transmission and/or CSI report and XR service image frame arrival time Offset accumulation leads to untimely CSI measurement or untimely sending of CSI reports, causing the base station to schedule based on outdated CSI, reducing the spectrum efficiency of downlink frame data transmission;

The time granularity of the cycle and offset of the uplink periodic SRS does not match the arrival time granularity of the uplink image frame data, resulting in the accumulation of offsets between the SRS transmission and the arrival time of the XR service image frame. As a result, the base station can only use the outdated Uplink channel measurement is used for uplink data scheduling, which reduces the efficiency of uplink image frame data transmission;

The period and offset time granularity of the periodic PUCCH-SR signal do not match the arrival time granularity of the image frame of the XR service, resulting in the accumulation of offsets between the transmission of the PUCCH-SR and the arrival time of the image frame of the XR service, resulting in the failure of the XR terminal to timely Sending SR increases the sending delay of the above image frame data.

In order to solve the above problem, the embodiment of the present application provides a time matching method. FIG. 6 is one of the schematic flow diagrams of the time matching method provided in the embodiment of the present application, including:

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

The terminal adjusts the first time window according to the time offset value between the first time window and the target window, so that the first time window matches the data transmission window of the target service, where the target window is based on The time window determined by the data transmission window.

In some optional implementation manners, the terminal re-matches each first periodic pattern with the arrival time or sending time of the image frame based on a periodic pattern re-matching configuration.

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.

Wherein, the first time window includes at least one of the following: a first period signal transmission time window, and a period information reporting time window.

Optionally, the first periodic signal transmission time window is the time domain window of the periodic signal resource, which may refer to any time point in the periodic signal start sending time, end sending time or continuous sending time, or refer to the periodic signal Any time point in the start receiving time, end receiving time or continuous receiving time of .

The periodic information reporting time window is the time window for periodic information transmission, which may be any time point in the period information start sending time, end sending time or continuous sending time.

Optionally, the periodic signal may be CSI-RS, PUCCH-SR or SRS; the periodic information may be a CSI report.

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

For example, the nth CSI-RS receiving time window, the nth CSI reporting time window, the nth PUCCH-SR sending time window and the SRS sending time window in each first periodic template are related to the Corresponding to arrival time, n is a positive integer greater than or equal to 1.

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

Optionally, the CSI-RS receiving time window, CSI reporting time window, PUCCH-SR sending time window and SRS sending time window in each first periodic template are determined according to a pre-configured period and offset.

In some optional implementation manners, the terminal matches the first time window with the data transmission window of the target service based on an automatic corrected rematching configuration manner.

Optionally, the network-side device configures an ideal period and offset (i.e. target period and offset) according to the arrival or transmission time of the image frame, and the terminal ensures the CSI-RS receiving time window and CSI reporting time window according to the ideal period and offset , The SRS transmission time window and the PUCCH-SR transmission time window always match the arrival time of the XR image frame. It can be understood that, according to the CSI-RS reception time window, CSI report time window, SRS transmission time window, PUCCH-SR transmission time window and the time offset value of their respective target windows, the terminal automatically corrects, so that subsequent CSI-RS reception The time window, the CSI reporting time window, the SRS sending time window and the PUCCH-SR sending time window match the XR image frames to be sent/received.

That is, the terminal adjusts the first time window according to the time offset value between 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 based on the target The time window determined by the data transmission window of the business.

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

The first periodic signal transmission time window and the periodic information reporting time window appear at the expected time, including:

The CSI-RS receiving time window and CSI reporting time window appear at the desired time, so that CSI can be measured and reported in time to ensure downlink adaptive performance;

The SRS transmission time window and the PUCCH-SR transmission time window appear at the expected time, so that the uplink channel can be measured in time, and the SR can be transmitted in time, so as to improve the performance of uplink adaptation and reduce the uplink transmission delay.

Optionally, adjusting the first time window refers to adjusting the period and offset of the periodic signal.

In the embodiment of the present application, the periodic signal transmission time window or the periodic information reporting time window matches the data transmission window of the target business through the configuration method based on periodic template rematching or the automatic correction rematching configuration method, which can ensure that the upper and lower Uplink adaptive performance, improved transmission efficiency, and reduced transmission delay.

Optionally, the terminal matches the first time window with the data transmission window of the target service based on the re-matching configuration of the first periodic template, including:

Re-matching each first time window in the first periodic template with the data transmission window of the target service, so that the difference between the position where each first time window appears and the target position is smaller than the first threshold X;

Wherein, the first threshold X is the maximum relative offset between the first time window in the first periodic template and the target position;

Wherein, the target location matches the data transmission window of the corresponding target service.

A first periodic template contains an integer number of time windows (for example, CSI-RS reception time window, CSI report time window, PUCCH-SR transmission time window or SRS transmission time window), and the time windows in each template are periodic , the appearance of the template is also periodic.

Each of the first time windows corresponds to a data transmission window of a target service. Optionally, the data of the target service is an XR service image frame as an example for illustration. The time length of a template is exactly equal to N (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 (called the target position, and the target position matches the arrival time of the corresponding image frame), then the relative accumulation of the last window in the template and the target position due to time granularity mismatch The offset is X=(N-1)*(picture frame period–window period). The window in each template is re-matched with the image frame. The maximum difference between the position of the window and the target position is X, which will not continue to increase with time; if N is small enough, X will not exceed the acceptable maximum value.

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

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

For example, the network side device needs to configure the period and offset of the CSI-RS template to the terminal through the RRC message, so that the position of each CSI-RS receiving time window in the first periodic template is the same as that of the target CSI-RS receiving time window. The deviation is less than a threshold. The configurations of the PUCCH-SR template and the SRS template are similar to this, and no examples are given here.

Optionally, the adjusting the first time window according to the time offset value between the first time window and the target window includes:

When the time offset value between the first time window and the target window exceeds a first preset threshold, adjust the period and offset of the first time window; or,

The period and offset of the first time window are adjusted according to the time offset value between the first time window and the target window every preset time.

The embodiment of the present application provides a trigger condition for adjusting the first time window.

In an implementation manner, when the time offset value between the first time window and the target window exceeds a first preset threshold, the terminal adjusts the period and offset of the first time window.

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

Optionally, the network side device configures a period and offset (CSI-RS window, CSI report window, PUCCH-SR transmission window or SRS transmission window), and its period and offset can be configured according to the absolute time of the 5G system for Determine the time when the target window appears, serve the corresponding image frame, and match the data transmission requirements 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 is negligible. The network-side device also provides a cycle and offset configuration of an effective window (CSI-RS receiving time window, CSI reporting time window, PUCCH-SR sending time window or SRS sending time window), which is used by the terminal or network-side device to determine the effective window The actual time of occurrence of the actual occurrence time, perform transmission, measurement and reporting operations, and its cycle and offset adopt the time granularity (time slot, Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing)) of 5G wireless access network (5G wireless access network, 5G-RAN) Frequency Division Multiplexing, OFDM) symbols, etc.) configuration, resulting in the time when the effective window appears and the time when the target window appears has a non-negligible offset, and it accumulates over time.

When the lag offset of the effective window relative to the target window exceeds a threshold, the terminal or network-side device compensates the position of the subsequent effective window forward by an offset, reducing the offset of the effective window relative to the target window to an acceptable range Inside. When the advanced offset of the effective window relative to the target window exceeds another threshold, the terminal or network side equipment compensates the position of the subsequent effective window backward by an offset, reducing the offset of the effective window relative to the target window to an acceptable level within range. The above two thresholds can be modeled as the same threshold. For example, when the absolute value of the cumulative offset between the effective window and the target window exceeds a preset threshold, the terminal or the network side device will compensate the position of the subsequent effective window by an offset, minus The offset of the small effective window relative to the target window is within an acceptable range.

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

Optionally, the terminal adjusts the cycle and offset configurations of CSI-RS, CSI report, SRS and PUCCH-SR every specified time.

Optionally, before adjusting the first time window according to the time offset value between the first time window and the target window, the method further includes:

Receive a PDCCH command or MAC CE sent by the network side device, where the PDCCH command or MAC CE is used to instruct the terminal to adjust the first time window.

It can be understood that the terminal receives a physical downlink control channel (Physical Downlink Control Channel, PDCCH) command sent by the network side device, and adjusts the first time window according to the instruction of the command.

Optionally, the terminal receives a media access control layer control element (Media Access Control Control Element, MAC CE) sent by the network side device, and adjusts the first time window according to an instruction of the MAC CE.

When the time offset value between the first time window and the target window exceeds a second preset threshold, adjust the period and offset of the first time window according to the first target adjustment amount;

Wherein, the first target adjustment amount is indicated by the network side device through the first dynamic signaling, and the first dynamic signaling includes downlink control information DCI or medium access control layer control unit MAC CE or radio resource control RRC signaling .

According to the time difference between the position of the above target window and the effective window (that is, the actual CSI-RS reception window, CSI report time window, PUCCH-SR transmission time window or SRS transmission time window), the terminal receives the dynamic command sent by the network side device , to adjust the position of the effective window.

The dynamic command can be sent by DCI, or by MAC CE or RRC signaling. The dynamic command carries the forward or backward adjustment offset of the effective window of the UE, that is, the first target adjustment amount. Wherein, the DCI may be identified by a pre-configured RNTI.

At this time, in addition to carrying the target adjustment amount, the first dynamic signaling, Also carries the first effective time.
