The data packets of the XR service can arrive at the buffer of the sending device at a fixed frequency (for example, 60 Hz, 90 Hz, 120 Hz) and wait for transmission. It can also be understood that there is a fixed arrival period (for example, when the fixed frequency is 60 Hz) , the arrival period is 16.67 milliseconds (ms)). XR services have service requirements of ultra-high bandwidth and ultra-low latency.

When the network device 130 is a core network, it can be connected to at least one base station, is a key control node in the communication system, and is mainly responsible for signaling processing functions, such as but not limited to functions such as access control, mobility management, and session management. .

In this application, the device for implementing the function of the network device 130 may be the network device 130 , or a device capable of supporting the network device 130 to realize the function, such as a chip system, and the device may be installed in the network device 130 .

As shown in FIG. 1 , the XR device 110 can directly connect with the network device 130 and transmit data for implementing XR services (XR data packets for short), or can connect and transmit XR data packets through the first device 120 and the network device 130 . Illustratively, the XR device 110 may send the acquired data to the XR server at a fixed first frequency (eg, 60 hertz (Hz), 90 Hz, 120 Hz) based on the need for graphics generation (for implementing AR effects and/or MR effects). The image of the current scene (ie the XR packet). Optionally, the above image may be an image acquired by the XR device 110 (eg, an AR device or an MR device) through a built-in camera. The XR server may be the first device 120 or the network device 130 . If the XR server is the network device 130, and the XR device 110 transmits data packets through the first device 120 and the network device 130, the first device 120 may send the above-mentioned image uploaded by the XR device 110 to the network device 130 at a fixed second frequency, The second frequency and the first frequency may be the same or different. The above process may be an uplink transmission process of XR data packets. Alternatively, to implement the downlink transmission process of the XR data packets, specifically, the XR server may acquire the XR data packets at a fixed third frequency, and send them to the XR device 110 . The XR server may be the first device 120 or the network device 130 . If the XR server is the network device 130, and the XR device 110 transmits data packets through the first device 120 and the network device 130, the first device 120 may send the XR data delivered by the network device 130 to the XR device 110 at a fixed fourth frequency Bag. The third frequency and the first frequency may be the same or different. The fourth frequency and the third frequency may be the same or different.

It should be noted that the above-mentioned fixed first frequency, second frequency, third frequency, and fourth frequency may be the frequency of the service data packet of the sending device, and optionally, may be the buffer ( buffer) frequency. For example, the XR data packet arrives at the buffer of the XR device 110 at the first frequency, that is, the sending device is the XR device 110 at this time, and the receiving device is the first device 120 or the network device 130 . The XR data packet arrives at the buffer of the first device 120 at the second frequency, that is, the sending device is the first device 120 at this time, and the receiving device is the XR device 110 or the network device 130 . During the downlink transmission, the XR data packet arrives at the buffer of the XR server at the third frequency, that is, the sending device is the XR server, and the receiving device is the XR device 110 or the device that relays transmission (eg, the first device 120 ). The XR data packet arrives at the buffer of the first device 120 at the fourth frequency, that is, the sending device is the first device 120 at this time, and the receiving device is the XR device 110 or the network device 130 .

It can be understood that the XR service has a fixed frequency, that is, the XR data packet arrives at the buffer of the sending device at a fixed frequency, and it can also be understood that there is a fixed arrival period. For example, when the frequency of the XR service is 60Hz, the arrival period is 1/60×1000=16.67 milliseconds (ms); or when the frequency is 90Hz, the arrival period is 1/90×1000=11.11ms; or when the frequency is 120Hz, the arrival period It is 1/120×1000=8.33ms. Understandably, every time an arrival period passes, an XR data packet arrives at the buffer of the sending device, and this moment can be called the arrival moment.

It should be noted that the form and quantity of the XR device 110, the first device 120, and the network device 130 shown in FIG. 1 are only used for example, and are not limited in this embodiment of the present application.

In current wireless communication scenarios (such as NR scenarios), uplink transmission can include two scheduling methods, dynamic scheduling and configured grant (CG) (also called scheduling-free), and downlink transmission can include dynamic scheduling and pre-configured grant (also called scheduling-free). Semi-persistent scheduling (semi-persistent scheduling, SPS)) two scheduling methods. Next, the above scheduling method is described by taking the transmission process between the UE and the base station as an example:

In the uplink transmission of dynamic scheduling, if the UE has data to be transmitted, it can send a scheduling request to the base station and report the amount of data to be transmitted. , the UE can send data to the base station through the configured transmission resources, and there are more signaling interactions and higher transmission delay. The uplink-free scheduling does not require the UE to send a scheduling request every time it transmits uplink data, nor does it need to wait for the base station to grant the scheduling of uplink resources. Instead, the UE performs a periodic transmission process autonomously on the pre-configured or activated transmission resources, avoiding dynamic scheduling. The extra delay introduced (ie, the delay caused by scheduling requests and grant scheduling). The uplink scheduling-free transmission modes may include two types: type 1 (type1) and type 2 (type2). The transmission parameters of type 1 are pre-configured by the base station through signaling at the radio resource control (radio resource control, RRC) layer. When there is data to be transmitted, the UE can directly use the pre-configured type1 transmission parameters without additional scheduling information, that is, it can directly send uplink data based on the pre-configured transmission period and on pre-configured or activated resources. For the type2 transmission mode, the base station not only configures transmission parameters through the signaling of the RRC layer, but also needs to activate uplink transmission through additional scheduling information: downlink control information (DCI), where DCI can indicate time-frequency resources. The specific configuration, modulation and coding scheme (modulation and coding scheme, MCS) level, multiple input multiple output (multiple input multiple output, MIMO) parameters, etc. After receiving the DCI, the UE can directly use the preconfigured transmission parameters when there is data to be transmitted, that is, the uplink data can be sent on the preconfigured or activated resources based on the preconfigured transmission period. Understandably, there is a transmission opportunity every time a transmission period elapses, and the UE can send uplink data only when the transmission opportunity arrives (this moment may be referred to as a transmission moment). If the UE has data to be transmitted, but the transmission opportunity has not arrived, it needs to wait until the transmission opportunity arrives before sending the data; if the transmission opportunity arrives, but the UE does not have data to be transmitted, the UE may not send the data, that is, skip this transmission opportunity.

In the downlink transmission of dynamic scheduling, the UE can always listen to the physical downlink control channel (PDCCH) and judge whether it is a cell radio network temporary identifier (C-RNTI) carried by the PDCCH. If the scheduling signaling for the own UE is the scheduling signaling for the own UE, the data sent by the base station is received based on the scheduling signaling. Every time the base station transmits downlink data, it needs to send a PDCCH to instruct the UE to receive the downlink data. There are many interactive signaling and high transmission delay. In the downlink SPS, the base station can configure the transmission period for the UE through the signaling of the RRC layer, and configure the transmission parameters of the downlink SPS such as the configured scheduling-radio network temporary identifier (CS-RNTI). The base station can complete processes such as SPS activation, deactivation, and retransmission through the PDCCH. Correspondingly, the UE can judge whether the SPS is activated by listening to the PDCCH, and obtain information of transmission resources. When performing downlink transmission for the first time, the base station can send the PDCCH scrambled by CS-RNTI to activate the SPS and indicate the transmission resources. After the SPS is activated, the UE may receive data sent by the base station on the preconfigured or activated resources based on the preconfigured transmission period. The UE may still receive PDCCH indicating new data transmission after SPS activation. Therefore, the base station can implement multiple downlink transmission processes by sending one PDCCH, reducing signaling overhead and transmission delay.

The communication system shown in Figure 1 can be applied to real-time broadband communication (RTBC) scenarios, aiming to support large bandwidth and low interaction delay. The goal is to achieve a given delay and certain reliability requirements. Increase the bandwidth by 10 times to create an immersive experience when people interact with the virtual world. XR services with ultra-high bandwidth and ultra-low latency requirements pose more severe challenges to current communication systems (eg, NR). Compared with dynamic scheduling, uplink-free scheduling and downlink SPS can better meet the low-latency requirements of XR services. However, both uplink-free scheduling and downlink SPS require the sending device to send data to the receiving device based on the pre-configured transmission cycle. The value is relatively limited and does not match the arrival period (that is, the difference between the ith transmission time in the transmission cycle and the ith arrival time in the arrival cycle is large, and i is a non-negative integer), so the transmission opportunity is easily wasted (also It can be understood that the scheduling resources are wasted), and the transmission delay is also relatively large.

Exemplarily, assuming that the frequency of the XR service is 60Hz, that is, the arrival period of the XR data packet is 16.67ms, then the subcarrier interval is 15kHz, the transmission period can be 10ms, 16ms and 20ms, which are similar to the arrival period, However, the difference between the ith transmission time in the transmission cycle and the ith arrival time in the arrival cycle is large, and i is a non-negative integer, so the transmission opportunity is easily wasted, and the transmission delay is also large. Specific examples of the transmission process are shown in Figures 2-5 below.

Referring to FIG. 2, FIG. 2 exemplarily shows a schematic diagram of transmission of an XR data packet.

As shown in Figure 2, the frequency of the XR service is 60Hz, that is, the arrival period T1 of the XR data packet to the buffer of the sending device is 16.67ms, that is, a new XR data packet arrives every T1, and the XR data packet arrives at the time of arrival. The sequence may be referred to as packet 0, packet 1, packet 2, . . . Each data packet can correspond to an arrival time, which can be characterized as data packet i corresponding to arrival time i, where i is a non-negative integer. For example, data packet 0 corresponds to arrival time 0 (ie, 0), and data packet 1 corresponds to arrival time 1 (ie, 16.67ms). The data packet j arrives after the arrival of the data packet 0 after j×T1, so the actual arrival time of the data packet j=the arrival time 0 of the data packet 0+j×T1, where j is a positive integer. It should be noted that the arrival time of any data packet is relative to the preset initial time 0, not the actual time. And without considering jitter, the present application takes the arrival time 0 of the data packet 0 as the preset initial time 0 as an example for description. Therefore, the arrival time j=j×T1 of the data packet j.

As shown in Figure 2, the transmission period T2 for the sending device to send data to the receiving device is 10ms, that is, there is a transmission opportunity every T2, which can be called transmission opportunity 0, transmission opportunity 1, Transmission Opportunity 2, …. The time when each transmission opportunity arrives may be referred to as the transmission time corresponding to the transmission opportunity, that is, it is characterized as the transmission time i corresponding to the transmission opportunity i. For example, transmission opportunity 0 corresponds to transmission time 0 (ie, 0), and transmission opportunity 1 corresponds to transmission time 1 (ie, 10 ms). The transmission opportunity j arrives after the arrival of the transmission opportunity 0 after j×T2, so the transmission time j corresponding to the transmission opportunity j=the transmission time 0 corresponding to the transmission opportunity 0+j×T2. It should be noted that any transmission moment is relative to the preset initial moment 0, not an actual moment. And without considering the initial offset, the present application takes the transmission time 0 as the preset initial time 0 as an example for description. Therefore, the transmission time j=j×T2 corresponding to the transmission opportunity j.

As shown in Figure 2, the arrival time 0 of the data packet 0 is equal to the transmission time 0 corresponding to the transmission opportunity 0 (both are 0), that is to say, the XR data packet arrives and the transmission opportunity arrives, then the sending device can use this transmission opportunity. (ie, transport opportunity 0) sends the incoming XR packet (ie, packet 0). The transmission time 1 is 10ms, and the arrival time 1 is 16.67ms, which means that the transmission opportunity arrives but the XR data packet does not arrive, the sending device can only skip this transmission opportunity (ie transmission opportunity 1), and transmission opportunity 1 is wasted (ie, the scheduled transmission resources used at transmission time 1 are wasted). For data packet 1, there is currently no transmission opportunity, that is, the XR data packet arrives but the transmission opportunity does not arrive, the sending device needs to wait for the next transmission opportunity (ie transmission opportunity 2) to arrive before sending data packet 1. The transmission time 3 of the transmission opportunity 2 is 20ms, so the sending device needs to wait for 20-16.67=3.33ms before using the transmission opportunity 2 to send the data packet 1, that is, the transmission delay of the data packet 1 is 3.33ms. The transmission process of the subsequent data packets is similar to the transmission process of the above-mentioned

data packets

0 and 1, and will not be described again.

As shown in Figure 2, transmission opportunity 1, transmission opportunity 3, transmission opportunity 6, and transmission opportunity 8 are all wasted, and the transmission delay of data packet 2 (ie, 40-33.34=6.66ms), the transmission delay of data packet 5 (ie 90-83.35=6.65ms) is larger.

In some embodiments, in order to avoid wasting transmission opportunities, the transmission period may also be set to a larger value than the arrival period, and a specific example is shown in FIG. 3 .

Referring to FIG. 3, FIG. 3 exemplarily shows a schematic diagram of transmission of another XR data packet. Wherein, Fig. 3 is similar to Fig. 2, except that the transmission period T2 is changed to 20ms, and at this time, T2 is greater than the arrival period T1=16.67ms.

As shown in FIG. 3 , the sending device uses the transmission opportunity i to send the data packet i, that is, one data packet uses one transmission opportunity, and there is no problem that the transmission opportunity is wasted, but the transmission delay of the data packet gradually increases. For example, compared with the transmission delay of packet 1, which is 20-16.67=3.33ms, the transmission delay of packet 2 increases to 40-33.34=6.66ms, and the transmission delay of packet 3 increases to 60-50=10ms . In this way, the transmission delay of subsequent XR data packets will increase, and the service delay will be uncontrollable, which cannot meet the low-latency requirements of XR services, affecting user experience.

In some embodiments, the encoder used to encode the XR data packets may generate a certain degree of jitter, that is, the time interval between the arrival of two adjacent XR data packets may not be the arrival period T1, which may be greater than the arrival period T1. The period T1 may also be smaller than the arrival period T1. For example, the time delay generated by jitter obeys a Gaussian distribution, for example, the time interval between the arrival of XR data packets obeys a Gaussian distribution with a mean of T1ms and a standard deviation of 3ms. As shown in Figure 3 above, the arrival time 0 before the jitter of the data packet 0 is the initial time 0, and the arrival time 0 fluctuates after the jitter occurs, such as 2.5ms. It should be noted that the fact that the time is a negative number only indicates that the time is a certain time before the initial time 0, not an actual time. An example of the transmission process considering jitter is shown in Figure 4 below.

Referring to FIG. 4, FIG. 4 exemplarily shows a transmission process of another XR data packet. Among them, Figure 4 is similar to Figure 2, the arrival period T1 is 10ms, the difference is: the arrival time of the XR data packet in Figure 4 may be unstable, for example, the arrival time 0 of the data packet 0 fluctuates, as shown in Figure 4 The arrival time 0 of the packet 1 is 3.5ms, and the arrival time 1 of the data packet 1 fluctuates, as shown in Figure 4, the arrival time 1 is 21.5ms.

And compared with Figure 2, Figure 4 also introduces an initial offset to reduce the impact of jitter (such as wasted transmission opportunities, increased transmission delay, etc.), that is, Figure 4 introduces a first offset offset1=5ms . Exemplarily, the initial offset may be the parameter timeDomainOffset in the 3rd generation partnership project (3rd generation partnership project, 3GPP) Release 17, which is used to indicate that the UE is in the time domain relative to the time domain reference system frame number (system frame number, SFN) (timeReferenceSFN) offset. That is, the UE may start periodic data transmission after receiving the timeDomainOffset after the SFN indicated by the timeReferenceSFN. Optionally, the initial offset may be determined by the UE itself. Compared with the transmission time i shown in Figure 2, in Figure 4 where the first offset offset1 is introduced, the transmission time i is delayed by offset1. For example, the transmission time 0 in Figure 2 is 0, while the transmission time 0 in Figure 4 is 0+offset1 =5ms. Although offset1 avoids the waste of transmission opportunity when some data packets are jittered, for example, if there is no offset1, when data packet 0 is jittered, transmission opportunity 0 will be wasted. However, the effect is not good, and the transmission period and the arrival period still do not match. For example, in Figure 4, transmission opportunity 1, transmission opportunity 4, transmission opportunity 6, and transmission opportunity 9 are all wasted, and the transmission delay of data packet 4 (75-66.68 = 8.32ms) is larger.

In some embodiments, the transmission period may also be set to a value closest to the arrival period, and a specific example is shown in FIG. 5 .

Referring to FIG. 5, FIG. 5 exemplarily shows a transmission process of another XR data packet.

As shown in Figure 5, the frequency of the XR service is 120 Hz, that is, the arrival period T1 is 8.33 ms. The transmission period T2 is set to the closest value to T1, that is, 8ms. Figure 5 also considers the effect of jitter, so in Figure 5, the arrival time of the XR data packet is also unstable. For example, the arrival time 6 of the data packet 6 fluctuates. The arrival time 6 in FIG. 5 is 53.5ms, and the arrival time 7 of the data packet 7 fluctuates. The arrival time 7 in FIG. 5 is 61.2ms. The conventions of XR data packets, arrival time, transmission opportunity, transmission time and initial time 0 are similar to those in Figure 2 above. The difference is that Figure 5 also introduces an initial offset to reduce the impact of jitter, that is, the introduction of the first An offset offset1=5ms, so the transmission time in FIG. 5 is delayed by offset1, for example, the transmission time 1 is the initial time 0 delayed by offset1, that is, 5ms.

As shown in Figure 5, although the transmission of data packet 0 to data packet 5 is good, the transmission opportunity 6 is wasted, and the transmission delay of data packet 6 (61-53.5=7.5ms), the transmission time of data packet 7 The delay (69-61.2=7.8ms), the transmission delay of the data packet 8 (77-69.5=7.5ms), and the transmission delay of the data packet 9 (85-77.5=7.5ms) are relatively large.

In the above-mentioned transmission process of the XR data packet, although the transmission period is adjusted and the initial offset is introduced, there are still problems that transmission opportunities are wasted and the transmission delay is relatively large.

In order to solve the above problem, the present application provides a scheduling transmission method, which can be applied to a sending device and a receiving device. The sending device and the receiving device can transmit service data packets based on preset configuration parameters.

Optionally, the above configuration parameters may be uplink scheduling-free or downlink SPS configuration parameters.

Optionally, the above configuration parameters may include a transmission period value and a time domain offset configured for every N consecutive transmission periods, that is, a periodic time domain offset (periodicalTimeDomainOffset).

Optionally, the above configuration parameters may include N time-domain offsets configured for every N consecutive transmission periods, that is, a periodic grouping time-domain offset (groupPeriodicalTimeDomainOffset), at least two of the N time-domain offsets different.

Optionally, the above configuration parameter may include values of N consecutive transmission periods, that is, a period group (groupPeriodicity), and at least two of the N values are different. That is, the transmission period may be changed periodically.

Optionally, the above N is a positive integer, and the value of N may be determined according to the period of the service data packet.

The present application can match the transmission period with the period of the service data packet (for example, the arrival period of the XR data packet) through the above configuration parameters, for example, the transmission time i is greater than the arrival time i, and the difference between the transmission time i and the arrival time i is smaller than the preset time difference (for example, 5ms), so as to avoid wasting transmission opportunities and reduce transmission delay.

Next, the electronic devices provided in the embodiments of the present application are exemplarily introduced.

Please refer to FIG. 6 , which shows a schematic structural diagram of an electronic device 200 . The electronic device 200 may be any one of the devices shown in FIG. 1 , such as the XR device 110 , the first device 120 or the network device 130 . That is to say, the electronic device 200 may be a sending device that sends XR data packets, or may be a receiving device that receives XR data packets. The electronic device 200 may include a processor 210, a memory 220, and a transceiver 230, and the processor 210, the memory 220, and the transceiver 230 are connected to each other through a bus.

The processor 210 may be one or more central processing units (central processing units, CPUs). In the case where the processor 210 is a CPU, the CPU may be a single-core CPU or a multi-core CPU. In some embodiments, the processor 210 may include multiple processing units, such as an application processor (AP), a modem (modem), and the like. Wherein, different processing units may be independent devices, or may be integrated in one or more processors. The memory 220 may include, but is not limited to, random access memory (RAM), read-only memory (ROM), erasable programmable read only memory (EPROM), Or portable read-only memory (compact disc read-only memory, CD-ROM). The memory 220 is used for storing relevant computer programs and information, optionally, the memory 220 is used for storing configuration parameters of uplink-free scheduling and downlink SPS; optionally, the memory 220 is used for storing XR data packets. The transceiver 230 is configured to receive and transmit information, such as uplink-free scheduling, downlink SPS configuration parameters, and XR data packets.

In some embodiments, the electronic device 200 may implement wireless communication technologies such as GSM, CDMA, WCDMA, SCDMA, UMTS, LTE, NR, or future networks through the processor 110 and the transceiver 230 . The electronic device 200 may communicate with other electronic devices through any wireless communication technology, such as transmitting uplink-free scheduling, downlink SPS configuration parameters, and XR data packets.

The processor 210 in the electronic device 200 is configured to read the computer program code stored in the memory 220 and execute the scheduling transmission method shown in FIG. 16 . The electronic device 200 is the terminal or network device shown in FIG. 16 .

Next, the XR data packet transmission process implemented by applying the scheduling transmission method provided by the present application is exemplarily introduced.

Embodiment 1: The transmitting device and the receiving device can realize the transmission process of the XR data packet through the preset periodic time domain offset (periodical Time Domain Offset), thereby reducing or avoiding the time domain offset caused by the mismatch between the transmission period and the arrival period. . Among them, every N consecutive transmission cycles, the periodicTimeDomainOffset takes effect once. Specifically, starting from the first transmission time, the transmission time after every N consecutive transmission cycles is delayed by the periodicTimeDomainOffset. The specific example is shown in Figure 7-Figure 9 below. .

Please refer to FIG. 7 , which exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, Fig. 7 is similar to Fig. 2 and Fig. 3 above, and the difference is that the frequency of the XR service is 60 Hz, that is, the arrival period T1 is 16.67 ms. The difference is that FIG. 7 not only introduces a periodic time domain offset (periodicalTimeDomainOffset), that is, the second offset offset2=5ms in FIG. 7, but also introduces a new value of the transmission period T2=15ms.

At the same time, FIG. 7 also introduces an initial offset, that is, the first offset offset1=5ms in FIG. 7 . Therefore, compared with the transmission time without offset1, in FIG. 7 where offset1 is introduced, the transmission time is delayed by offset1. For example, before offset1 is introduced, the transmission time 0, transmission time 1, transmission time 2, and transmission time 3 in the transmission cycle are: 0, 15ms, 30ms, 45ms in sequence; after the introduction of offset1, in the transmission cycle shown in Figure 7, Transmission time 0, transmission time 1, transmission time 2, and transmission time 3 are all delayed by offset1=5ms, that is, 5ms, 20ms, 35ms, and 50ms in sequence.

As shown in FIG. 7 , the second offset offset2 takes effect once every N=3 transmission cycles starting from transmission time 0 (ie, 5ms). Therefore, compared with the transmission process in which offset2 is not introduced, every N=3 transmission cycles in FIG. 7 The transmission time after the transmission period is delayed by an offset2. That is to say, the transmission times after i times of N=3 transmission cycles from the transmission time 0 are all delayed by i×offset2. For example, after 1 N=3 transmission cycles from transmission time 0 (ie 5ms), transmission time 4, transmission time 5 and transmission opportunity 6 in the next N=3 transmission cycles are delayed by offset2, such as after offset2 is introduced In Figure 7, the transmission time 4=65+offset2=70ms.

The value of N may be determined according to the arrival period, that is, since the sum of every three arrival periods (3×16.67=50ms) is an integer, N=3. The second offset offset2 can satisfy that the sum of N consecutive transmission periods T2 and offset2 is equal to the sum of N arrival periods T1, that is, it satisfies N×T2+offset2=N×T1, so offset2=N×T1-N×T2 =3×16.67-3×15=5ms.

Optionally, N consecutive transmission periods and offset2 may form a new period: the preset period T0=N×T2+offset2=3×15+5=50ms. The preset period may include N consecutive transmission periods, that is, N+1 transmission moments have passed. Wherein, the start time of the preset period is the transmission time that arrives first among the N+1 transmission times, and the end time is the time when the last transmission time of the N+1 transmission times passes through offset2. For example, for the first preset period starting from the initial time 0, the starting time is the transmission time 0 (ie 5ms), that is, the time when the initial time 0 passes the first offset offset1 (ie 5ms); the end time is the transmission time 3 (ie 50ms) passes through the moment of offset2 (ie 5ms) (ie 55ms), it can also be understood as the time from the start time (ie 5ms) after N×T2+offset2 (ie 3×15+5=50ms) time (ie 5+50=55ms).

Comparing FIG. 2 , FIG. 3 and FIG. 7 , it can be seen that FIG. 7 introduces a new value of the transmission period and introduces a second offset offset2. Therefore, compared with FIG. 2, transmission opportunity 1, transmission opportunity 3, transmission opportunity 6, and transmission opportunity 8 in FIG. 7 are not wasted; and, compared with FIG. 5ms), the matching of the transmission period and the arrival period is realized, and the user experience is better.

Comparing FIG. 4 and FIG. 7 , it can be seen that although the first offset offset1 remains unchanged, FIG. 7 introduces a new value of the transmission period and introduces the second offset offset2. Therefore, even if there is no jitter in the XR data packet in Figure 4, transmission opportunity 1, transmission opportunity 4, and transmission opportunity 6 are still wasted, while in Figure 7, these transmission opportunities are not wasted, and the transmission delay of the data packet is small. (for example, less than or equal to 5ms), the user experience is better.

In some embodiments, the initial offset can also be adjusted, for example, by increasing the first offset offset1 to 10ms, so as to achieve the expectation that the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, so as to avoid A specific example of the impact of jitter on XR data packets is shown in Figure 8 below.

Referring to FIG. 8, FIG. 8 exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, compared with Fig. 7, during the transmission process shown in Fig. 8, the XR data packet may be jittered, and the jitter situation is the same as that shown in Fig. 4 above, and will not be repeated. In order to avoid the waste of transmission opportunities and the increase of transmission delay caused by jitter, it is expected that the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, then the first offset can be adjusted to offset1=10ms . Therefore, compared with the transmission process shown in FIG. 7 , the transmission moments shown in FIG. 8 are all delayed by 5ms.

Comparing Figure 4 with Figure 8, it can be seen that although the XR data packets are all jittered and the first offset offset1 remains unchanged, Figure 8 introduces a new value of the transmission period and introduces a second offset offset2. Therefore, compared with Fig. 4, the transmission opportunity 1, transmission opportunity 4, and transmission opportunity 6 in Fig. 8 are not wasted, and the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, thereby reducing the The impact of XR packet jitter (that is, the transmission opportunity is wasted and the transmission delay is large), the user experience is better.

It should be noted that, in the specific implementation, the arrival time i of the data packet i is not necessarily at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, or 4ms earlier than the transmission time i due to jitter, that is to say, the above 5ms is only are expected values and should not be construed as limitations. In addition, the expected value can also be set to other values, for example, 3ms, and the first offset offset1 can be set to 8ms. The application does not limit the specific values of the expected value and the initial offset.

In some embodiments, a new transmission period value may not be introduced, and only a periodic time domain offset (periodicalTimeDomainOffset) may be introduced. A specific example is shown in FIG. 9 below.

Referring to FIG. 9, FIG. 9 exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, Fig. 9 is similar to Fig. 5 above, and the similarities are: the frequency of the XR service is 120Hz, that is, the arrival period T1 is 8.33ms; the transmission period T2 is 8ms, the first offset offset1=5ms; the jitter of the XR data packet It is also consistent with the jitter situation in Figure 5 above. The difference is that a periodic time domain offset (periodicalTimeDomainOffset) is introduced in FIG. 9 , that is, the second offset offset2=1ms in FIG. 9 .

As shown in FIG. 9 , every N=3 transmission cycles starting from transmission time 1 (ie, 5 ms), the second offset offset2 takes effect once. Therefore, compared with the transmission process shown in FIG. 5 without introducing offset2, in FIG. 9 The transmission time after every N=3 transmission cycles is delayed by one offset2. That is to say, the transmission times after i times of N=3 transmission cycles from the transmission time 0 are all delayed by i×offset2. For example, after 1 N=3 transmission cycles from transmission time 0 (ie 5ms), transmission time 4, transmission time 5 and transmission time 6 in the next N=3 transmission cycles are delayed by offset2, such as transmission time 4 In FIG. 5 , it is 37ms, and in FIG. 9 after introducing offset2, transmission time 4=37+offset2=38ms. After 2 N=3 transmission cycles from transmission time 0, transmission time 7, transmission time 8, and transmission time 9 in the next N=3 transmission cycles are all delayed by 2×offset2, such as transmission time 7 in Figure 5 is 61ms, and the transmission time 7=61+2×offset2=63ms in FIG. 9 after the introduction of offset2.

The value of N may be determined according to the arrival period T1, that is, since the sum of every three arrival periods (3×8.33=25ms) is an integer (the transmission period T2 is an integer), N=3. The second offset offset2 can be determined according to N, the arrival period T1 and the transmission period T2, which can satisfy the sum of N consecutive transmission periods T2 and offset2 equal to the sum of N arrival periods T1, that is, N×T2+offset2 =N×T1, so offset2=N×T1-N×T2=3×8.33-3×8=1ms.

Optionally, N consecutive transmission periods and offset2 may form a new period: the preset period T0=N×T2+offset2=3×8+1=25ms. The preset period may include N consecutive transmission periods, that is, N+1 transmission moments have passed. Wherein, the start time of the preset period is the transmission time that arrives first among the N+1 transmission times, and the end time is the time when the last transmission time of the N+1 transmission times passes through offset2. For example, for the first preset period starting from the initial time 0, the starting time is the transmission time 0 (ie 5ms), that is, the time when the initial time 0 passes the first offset offset1 (ie 5ms); the end time is the transmission time 3 (ie 29ms) passes through the moment of offset2 (ie 1ms) (ie 30ms), it can also be understood as N×T2+offset2 (ie 3×8+1=25ms) after the above starting time (ie 5ms) time (ie 5+25=30ms).

Comparing Figure 5 and Figure 9, it can be seen that although the XR data packets are all jittered, and the first offset offset1 and the transmission period T2 remain unchanged, Figure 9 introduces a second offset offset2. Therefore, compared with Figure 5, the transmission opportunity 6 in Figure 9 is not wasted, and the transmission delay of the data packet 6 (54-53.5=0.5ms), the transmission delay of the data packet 7 (63-61.2=1.8ms), The transmission delay of packet 8 (71-69.5=1.5ms) and the transmission delay of packet 9 (79-77.5=1.5ms) are both small, thereby reducing the impact of XR packet jitter (that is, transmission The opportunity is wasted, the transmission delay is large), and the user experience is better.

Not limited to the above-mentioned cases, in specific implementation, the transmission period may also have other values, for example, when the arrival period is 16.67ms, the transmission period is 17ms, which is not limited in this application.

Not limited to the cases listed above, in specific implementation, N may also have other values. When the transmission period is less than the arrival period, N can be determined according to the arrival period T1, the transmission period T2 and the initial offset (ie, the first offset offset1), that is, the following formula is satisfied:

0≤N×T2+offset1-N×T1≤x

That is, N satisfies the following formula:

Among them, T1-T2≤offset1, x is a non-negative number, optionally, x is the tolerable waiting delay of the XR data packet, that is, the maximum tolerable delay of the arrival period and the transmission period.

Exemplarily, assuming that the arrival period is T1=16.67ms, and the transmission period is T=15ms, the values of N, the first offset offset1 and x may have various situations. Assuming that x is less than 5ms, for example, 3ms, and T1-T2=1.67ms≤offset1, assuming that the value of offset1 is 2ms, N satisfies max(0.6,1)≤N≤1.2, so the value of N is 1. Or assume that x is greater than or equal to 5ms, for example, 5ms, and assume that the value of offset1 is 4ms, then N satisfies max(0.6,1)≤N≤2.4, so the value of N is 1 or 2. Or suppose that x is 5ms and offset1 is 5ms, then N satisfies max(0,1)≤N≤3, so the value of N includes 1, 2 and 3. Or suppose that x is 5ms and offset1 is 7ms, then N satisfies max(-1.2,1)≤N≤4.2, so the values of N include 1, 2, 3 and 4. Or suppose that x is 5ms and the offset1 value is 10ms, then N satisfies max(-2.99,1)≤N≤6, so the value of N includes 1, 2, 3, 4, 5 and 6, for example, in Figure 8 above N can also take a value of 1, 2, 4, 5, or 6.

When the transmission period is greater than the arrival period, N can be determined according to the arrival period T1 and the transmission period T2, that is, the following formula is satisfied:

N×T2-N×T1≤y

That is, N satisfies the following formula:

Among them, y is a non-negative number, and optionally, y is the tolerable waiting delay of the XR data packet, that is, the maximum tolerable delay of the arrival period and the transmission period.

Exemplarily, assuming that the initial offset is 0ms, the transmission period T2=17ms, and the arrival period T1=16.67ms, the values of N and y can be in various situations. For example, if y is 2ms, N satisfies N≤6.06, so the values of N include 1, 2, 3, 4, 5, and 6.

Alternatively, N can also be directly determined. For example, in the above Figure 7, N can also be an integer multiple of 3 such as 6, 9, etc., or any positive integer such as 1, 2, 4, and 5. Or, when the frequency of the XR service is 90Hz, the arrival period T1 is 11.11ms, and N is an integer multiple of 9, 18, etc. (9×11.11=100ms, that is, the sum of 9 arrival periods is an integer), or 1, 3, 6, 10, etc. any positive integer. This application does not limit the value manner of N.

Not limited to the above listed cases, in specific implementation, the periodic time domain offset (periodicalTimeDomainOffset), that is, the above offset2 may also have other values, but offset2=N×T1−N×T2 is required to be satisfied. It can be understood that there is a situation where offset2 is less than 0 at this time. For example, the arrival period is 16.67ms, the transmission period is 17ms, and when N is 3, offset2=3×16.67-3×17=-1ms.

Not limited to the cases listed above, in a specific implementation, the periodic time domain offset (periodicalTimeDomainOffset), that is, the above offset2 may not be the N+1th transmission in every N consecutive transmission periods (that is, a preset period). After the moment (it can also be understood as between two preset periods), for example, in Figure 7 above, offset2 is located between the first preset period and the second preset period, that is, the first preset period After the third transmission time (ie, transmission time 3). offset2 can be before or after any one of the N+1 transmission moments in every N consecutive transmission cycles (ie, a preset cycle). For example, in Figure 7 above, offset2 is located before the Nth transmission moment, that is, The offset1 is located before the transmission time 2 of the first preset period, and is located before the transmission time 5 of the second preset period. At this time, the transmission time 0 to the transmission time 6 are respectively: 5ms, 20ms, 40ms (that is, after the transmission time 1 after T2+offset2=15+5=20ms), 55ms (the first preset period), 70ms, 90ms ( That is, after the transmission time 4, T2+offset2=15+5=20ms) and 105ms (the second preset period).

In the transmission process shown in the first embodiment, a periodic time domain offset (periodicalTimeDomainOffset) is introduced to reduce or avoid the time domain offset caused by the mismatch between the transmission period and the arrival period, so as to realize the transmission period and the arrival period. cycle matching. In addition, combined with the introduction of a new transmission period value, adjusting the existing initial offset further reduces the impact of XR packet jitter, avoids wasting transmission opportunities, reduces transmission delay, and provides a better user experience.

Embodiment 2: The transmitting device and the receiving device can realize the transmission process of the XR data packet through the pre-configured periodic grouping time domain offset (groupPeriodicalTimeDomainOffset), wherein, every N consecutive transmission cycles, the groupPeriodicalTimeDomainOffset takes effect once, and the periodicTimeDomainOffset includes N times. The domain offset is respectively configured for N consecutive transmission cycles, specifically: starting from the first transmission time, the transmission time after every N consecutive transmission cycles is delayed by the above N time domain offsets, specifically Examples are shown in Figures 10-12 below.

Please refer to FIG. 10 , FIG. 10 exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, Fig. 10 is similar to Fig. 2 and Fig. 3 above, and the difference is that the frequency of the XR service is 60 Hz, that is, the arrival period T1 is 16.67 ms. The difference is that FIG. 10 not only introduces the periodic grouping time domain offset (groupPeriodicalTimeDomainOffset), that is, offset3, offset4, and offset5 in FIG. 10 .

As shown in Figure 10, every N=3 transmission cycles starting from transmission time 0 (ie 0ms), groupPeriodicalTimeDomainOffset={offset3, offset4, offset5} takes effect once. Therefore, compared with the transmission process in which groupPeriodicalTimeDomainOffset is not introduced, in Figure 10, In every N=3 transmission periods starting from transmission time 0, the first transmission period becomes T2+offset3, the second transmission period becomes T2+offset4, and the third transmission period becomes T3+offset5. After every N=3 transmission cycles, N+1 transmission moments have passed, and the N time domain offsets in groupPeriodicalTimeDomainOffset correspond to the last N consecutive transmission moments in the N+1 transmission moments, that is, N+1 transmission moments. The k-th arriving transmission time in the transmission time is delayed by offset(k-1). For example, for the first N=3 transmission periods that elapse from transmission time 0 (ie, 0 ms), N+1=4 transmission times have elapsed: transmission opportunity 0, transmission opportunity 1, transmission opportunity 2, and transmission opportunity 3. The above offset3, offset4, and offset5 correspond to transmission opportunity 1, transmission opportunity 2, and transmission opportunity 3 in turn, that is, transmission time 1 in Figure 10 is delayed by offset3 (ie 2ms) compared to transmission time 1 (ie 15ms) without groupPeriodicalTimeDomainOffset introduced in Figure 10, which is 15 +2=17ms; the transmission time 2 in Figure 10 is delayed by offset3+offset4=2+2=4ms compared to the transmission time 2 (ie 30ms) without groupPeriodicalTimeDomainOffset, which is 30+4=34ms; the transmission time 3 in Figure 10 The delay offset3+offset4+offset5=2+2+1=5ms is delayed from the transmission time 3 (ie, 45ms) in which the groupPeriodicalTimeDomainOffset is not introduced, that is, 45+5=50ms. For the value of N, reference may be made to the description of FIG. 7 above, and details are not repeated here.

Optionally, N consecutive transmission periods and groupPeriodicalTimeDomainOffset may form a new period: the preset period T0=N×T2+offset3+offset4+offset5=3×15+2+2+1=50ms. The preset period may include N consecutive transmission periods, that is, N+1 transmission moments have passed. The start time of the preset period is the transmission time that arrives first among the N+1 transmission times, and the end time is the last transmission time that arrives among the N+1 transmission times. For example, for the first preset period starting from the initial time 0, the starting time is the transmission time 0 (ie 0ms), and the end time is the transmission time 3 (ie 50ms). That is, after the start of 0ms), the time of N×T2+offset3+offset4+offset5=3×15+5=50ms (ie, 0+50=50ms) passes.

Comparing FIG. 2 , FIG. 3 and FIG. 10 , it can be seen that FIG. 10 introduces a new value of the transmission period, and introduces a third offset offset3 , a fourth offset offset4 and a fifth offset offset5 . Therefore, compared with Fig. 2, the transmission opportunity 1, transmission opportunity 3, transmission opportunity 6, and transmission opportunity 8 in Fig. 10 are not wasted; and, compared with Fig. 3, the transmission delay of the data packet is smaller (for example, less than 1ms). ), the matching of the transmission period and the arrival period is realized, and the user experience is better.

In some embodiments, the initial offset can also be adjusted, for example, the first offset offset1 is set to 5ms, so as to achieve the expectation that the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, so as to avoid XR A specific example of the impact of packet jitter is shown in Figure 11 below.

Please refer to FIG. 11 , FIG. 11 exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, compared with Fig. 10, during the transmission process shown in Fig. 11, the XR data packet may be jittered, and the jitter situation is the same as that shown in Fig. 4 above, and will not be repeated here. In order to avoid the waste of transmission opportunities and the increase of transmission delay caused by jitter, it is expected that the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, then set the first offset offset1=5ms, so , compared with the transmission process shown in FIG. 10 , the transmission moments shown in FIG. 11 are all delayed by offset1 (ie, 5ms).

Comparing Figure 4 and Figure 11, it can be seen that although the first offset offset1 remains unchanged, Figure 11 introduces a new value of the transmission period, and introduces a third offset offset3, a fourth offset offset4 and a fifth offset Shift offset5. Therefore, compared with Fig. 4, the transmission opportunity 1, transmission opportunity 4, and transmission opportunity 6 in Fig. 11 are not wasted, and the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, thereby reducing the The impact of XR packet jitter (that is, the transmission opportunity is wasted and the transmission delay is large), the user experience is better.

It should be noted that, in the specific implementation, the arrival time i of the data packet i is not necessarily at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, or 4ms earlier than the transmission time i due to jitter, that is to say, the above 5ms is only are expected values and should not be construed as limitations. In addition, the expected value may also be set to other values, for example, 3ms, and the first offset offset1 may be set to 3ms, and the specific values of the expected value and the initial offset are not limited in this application.

In some embodiments, a new transmission period value may not be introduced, but only a periodic grouping time domain offset (groupPeriodicalTimeDomainOffset) may be introduced. A specific example is shown in FIG. 12 below.

Please refer to FIG. 12, FIG. 12 exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, Fig. 12 is similar to Fig. 5 above, and the similarities are: the frequency of the XR service is 120Hz, that is, the arrival period T1 is 8.33ms; the transmission period T2 is 8ms, the first offset offset1=5ms; the jitter of the XR data packet It is also consistent with the jitter situation in Figure 5 above. The difference is that a periodic grouping time domain offset (groupPeriodicalTimeDomainOffset) is introduced in FIG. 12 , that is, offset3 , offset4 , and offset5 in FIG. 12 .

As shown in FIG. 12 , groupPeriodicalTimeDomainOffset={offset3, offset4, offset5} takes effect once every N=3 transmission cycles starting from transmission time 1 (ie, 5ms). Therefore, compared with the transmission process shown in FIG. 5 that does not introduce groupPeriodicalTimeDomainOffset , in Figure 12, in every N=3 transmission cycles starting from transmission time 0, the first transmission cycle becomes T2+offset3, the second transmission cycle becomes T2+offset4, and the third transmission cycle becomes T3 +offset5. N+1 transmission moments have passed every N=3 transmission periods, and the N time domain offsets in the groupPeriodicalTimeDomainOffset correspond to the last N consecutive transmission moments in the N+1 transmission moments respectively. For example, for the first N=3 transmission periods that elapse from transmission time 0 (ie, 5 ms), N+1=4 transmission times have elapsed: transmission opportunity 0, transmission opportunity 1, transmission opportunity 2, and transmission opportunity 3. The above offset3, offset4, and offset5 correspond to transmission opportunity 1, transmission opportunity 2 and transmission opportunity 3 in turn, that is, the transmission time 1 in Figure 12 is delayed by offset3 (ie 0.4ms) compared to the transmission time 1 (13ms) shown in Figure 5, that is is 13+0.4=13.4ms; the transmission time 2 in Figure 12 is delayed by offset3+offset4=0.4+0.4=0.8ms compared to the transmission time 2 (ie 21ms) shown in Figure 5, which is 21+0.8=21.8ms; The transmission time 3 in 12 is delayed by offset3+offset4+offset5=0.4+0.4+0.2=1ms compared to the transmission time 3 (ie 29ms) shown in FIG. 5 , that is, 29+1=30ms. For the value of N, reference may be made to the description of FIG. 9 above, and details are not repeated here.

Optionally, N consecutive transmission periods and groupPeriodicalTimeDomainOffset may form a new period: the preset period T0=N×T2+offset3+offset4+offset5=3×8+0.4+0.4+0.2=25ms. The preset period may include N consecutive transmission periods, that is, N+1 transmission moments have passed. The start time of the preset period is the transmission time that arrives first among the N+1 transmission times, and the end time is the last transmission time that arrives among the N+1 transmission times. For example, for the first preset period starting from the initial time 0, the starting time is the transmission time 0 (ie 5ms), that is, the time when the initial time 0 passes the first offset offset1 (ie 5ms); the end time is the transmission time 3 (ie 30ms) can also be understood as a time (ie, 5+25=30ms) after N×T2+offset3+offset4+offset5=3×8+1=25ms after the start time (ie 5ms).

Comparing Figure 5 and Figure 12, it can be seen that although the XR data packets are all jittered, and the first offset offset1 and the transmission period T2 remain unchanged, Figure 12 introduces offset3, offset4 and offset5. Therefore, compared with Figure 5, the transmission opportunity 6 in Figure 12 is not wasted, and the transmission delay of the data packet 6 (55-53.5=1.5ms), the transmission delay of the data packet 7 (63.4-61.2=2.2ms), The transmission delay of packet 8 (71.8-69.5=2.3ms) and the transmission delay of packet 9 (80-77.5=2.5ms) are both small, thereby reducing the impact of XR packet jitter (that is, transmission The opportunity is wasted, the transmission delay is large), and the user experience is better.

Not limited to the cases listed above, in the specific implementation, N can also have other values. For example, in Figure 11 above, N can directly take the value of an integer multiple of 3 such as 6, 9, or 1, 2, 4, 5, etc. any positive integer. Or, when the frequency of the XR service is 90Hz, the arrival period T1 is 11.11ms, and N is an integer multiple of 9, 18, etc. (9×11.11=100ms, that is, the sum of 9 arrival periods is an integer), or 1, 3, 6, 10, etc. any positive integer. This application does not limit the value manner of N.

Not limited to the cases listed above, offset3, offset4, and offset5 may also have other values. For example, the values in FIG. 12 are 0.1ms, 0.5ms, 0.4ms, etc. This application includes the periodic grouping time domain offset (groupPeriodicalTimeDomainOffset). The value of the N time domain offsets is not limited, but the sum of the N time domain offsets is required to be N×T1-N×T2, which is also the periodic time domain offset (periodicalTimeDomainOffset) in the first embodiment, That is, the second offset offset2 shown in Figures 7-9 above. It can be understood that there is a situation where the sum of the N time-domain offsets is less than 0. For example, when the arrival period is 16.67ms, the transmission period is 17ms, and N is 3, the sum of the N time-domain offsets As 3×16.67-3×17=-1, offset3, offset4, and offset5 can be respectively -0.1ms, -0.5ms, and -0.4ms. Assuming that the initial offset offset1 = 0, the transmission time 0 to transmission time 3 (ie, the first preset period) before the N time domain offsets are not used are: 0ms, 17ms, 34ms, 51ms, and these N time-domain offsets are used. Transmission time 0 to transmission time 3 before the time domain offset are: 0ms, 16.9ms, 33.4ms, and 50ms, respectively.

Not limited to the cases listed above, in a specific implementation, the N time domain offsets in the periodic grouping time domain offset (groupPeriodicalTimeDomainOffset), that is, the above offset3, offset4, and offset5 may also not be in every N consecutive transmission cycles (ie, After the first N consecutive transmission moments in a preset cycle), for example, in Figure 10 above, offset3, offset4, and offset5 are respectively located in the first 3 transmission moments in the first preset cycle (ie, transmission time 0, transmission time 1 and after the transmission time 2). Any one of the N time domain offsets may be before or after any transmission moment in every N consecutive transmission periods (ie, a preset period), for example, it may be within the next N consecutive transmission times. Before the transmission time, in Figure 10 above, offset3, offset4, and offset5 are located before transmission time 1, transmission time 2, and transmission time 3, respectively. At this time, transmission time 0 to transmission time 3 are respectively: 0ms, 17ms, 34ms, 50ms . Or it can be partly before the transmission time and partly at the transmission time. In Figure 10 above, offset3 and offset4 are located before transmission time 0 and transmission time 1, and offset5 is located after transmission time 2. At this time, transmission time 0 to transmission time 3 are respectively : 2ms, 19ms, 34ms, 50ms.

Not limited to the cases listed above, offset1 can also have other values, such as 3ms, to assist the above-mentioned newly introduced periodic grouping time domain offset (groupPeriodicalTimeDomainOffset), optionally and the value of the newly introduced transmission period, to realize the transmission period and the matching of the arrival period.

Not limited to the above-mentioned cases, in the specific implementation, other new transmission period values may also be introduced. For example, when the arrival period is 8.33ms, the transmission period may be set to 7ms, which is not limited in this application.

In the transmission process shown in the second embodiment, a periodic grouping time domain offset (groupPeriodicalTimeDomainOffset) is introduced, so that the time domain offset caused by the mismatch between the transmission period and the arrival period can be reduced or avoided, wherein the groupPeriodicalTimeDomainOffset includes the configuration to N time domain offsets for N consecutive transmission cycles, the difference (instant delay) between transmission time i and arrival time i is more uniform and stable. The experience is better. In addition, combined with the introduction of a new transmission period value, the existing initial offset is adjusted to further reduce the impact of the XR data packet jitter, avoid wasting transmission opportunities, and reduce transmission delay.

Embodiment 3: The transmitting device and the receiving device can implement the transmission process of the XR data packet through a pre-configured periodic grouping (groupPeriodicity), wherein, every N consecutive transmission periods, the groupPeriodicity takes effect once, and the groupPeriodicity includes these N consecutive transmission periods. The values of the N consecutive transmission periods may be the same or different. That is to say, the transmission period during which the sending device sends the XR data packet to the receiving device may not be a fixed value, but fluctuate periodically. Specific examples are shown in Figures 13-15 below.

Please refer to FIG. 13, FIG. 13 exemplarily shows a transmission process of another XR data packet. Among them, Fig. 13 is similar to Fig. 2 and Fig. 3 above, and the difference is that the frequency of the XR service is 60 Hz, that is, the arrival period T1 is 16.67 ms. The difference is that Fig. 13 also introduces periodic grouping (groupPeriodicity), namely T21, T22, T23 in Fig. 13 .

As shown in Figure 13, every N=3 transmission periods starting from transmission time 1 (ie 0ms), groupPeriodicity={T21, T22, T23} takes effect once, so compared to the transmission process without groupPeriodicity, in Figure 13, In every N=3 transmission periods starting from transmission time 0, the first transmission period becomes T21, the second transmission period becomes T22, and the third transmission period becomes T23. The sum of N consecutive transmission periods included in groupPeriodicity is equal to the sum of N arrival periods, that is, T21+T22+T23=N×T1. For example, for the first N=3 transmission periods that elapse from transmission time 0 (ie 0ms), the transmission period between transmission opportunity 0 and transmission opportunity 1 is T21=17ms, and the transmission period between transmission opportunity 1 and transmission opportunity 2 is T21=17ms. The transmission period is T22=17ms, and the transmission period between transmission opportunity 2 and transmission opportunity 3 is T23=16ms. T21+T22+T23=17+17+16=50ms=N×T1=3×16.67. Moreover, due to the change in the periodic interval, the transmission time 2 is no longer the time 15ms after transmission time 0 (ie 0ms) (ie 0+15=15ms), but the time after the transmission time 0 after T21 (ie 0 +17=17ms). Similarly, the transmission time 2 is also the time T22 after the transmission time 1 (ie 17+17=34ms), and the transmission time 3 is also the time after the transmission time 2 and the time T23 (ie 34+16=50ms). For the value of N, reference may be made to the description of FIG. 7 above, and details are not repeated here.

Optionally, N consecutive transmission periods represented by groupPeriodicity may constitute a new period: the preset period T0=T21+T22+T23=17+17+16=50ms. The preset period may include N continuous transmission periods represented by groupPeriodicity, and the values of the N continuous transmission periods may be the same or different, and the specific values are not limited. The start time of the preset period is the transmission time that arrives first among the N+1 transmission times, and the end time is the last transmission time that arrives among the N+1 transmission times. For example, for the first preset period starting from the initial time 0, the starting time is the transmission time 0 (ie 0ms), and the end time is the transmission time 3 (ie 50ms). That is, after the start of 0ms), the time T21+T22+T23=17+17+16=50ms (ie, 0+50=50ms) passes.

Comparing Figure 2, Figure 3 and Figure 13, it can be seen that Figure 13 introduces T21, T22 and T23. Therefore, compared with Fig. 2, the transmission opportunity 1, transmission opportunity 3, transmission opportunity 6, and transmission opportunity 8 in Fig. 13 are not wasted; and, compared with Fig. 3, the transmission delay of the data packet is smaller (for example, less than 1ms ), the matching of the transmission period and the arrival period is realized, and the user experience is better.

In some embodiments, the initial offset can also be adjusted, for example, the first offset offset1 is set to 5ms, so as to achieve the expectation that the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, so as to avoid XR A specific example of the impact of packet jitter is shown in Figure 14 below.

Please refer to FIG. 14 , which exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, compared with Fig. 13, in the transmission process shown in Fig. 14, the XR data packet may be jittered, and the jitter situation is the same as that shown in Fig. 4 above, and will not be repeated. In order to avoid the waste of transmission opportunities and the increase of transmission delay caused by jitter, it is expected that the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, then set the first offset offset1=5ms, so , compared with the transmission process shown in FIG. 13 , the transmission moments shown in FIG. 14 are all delayed by offset1 (ie, 5ms).

Comparing Fig. 4 and Fig. 14, we can see that although the first offset offset1 remains unchanged, Fig. 14 introduces T21, T22 and T23. Therefore, compared with Fig. 4, the transmission opportunity 1, transmission opportunity 4, and transmission opportunity 6 in Fig. 14 are not wasted, and the arrival time i of the data packet i is at least 5ms earlier than the transmission time i corresponding to the transmission opportunity i, thereby reducing the The impact of XR packet jitter (that is, the transmission opportunity is wasted and the transmission delay is large), the user experience is better.

Please refer to FIG. 15 , which exemplarily shows a schematic diagram of transmission of another XR data packet. Among them, Figure 15 is similar to Figure 5 above, and the same is that the frequency of the XR service is 120Hz, that is, the arrival period T1 is 8.33ms, and the first offset offset1=5ms; the jitter of the XR data packet is also the same as that in Figure 5 above. The jitter is the same. The difference is that FIG. 15 introduces periodic grouping (groupPeriodicity), namely T21 , T22 and T23 in FIG. 15 .

As shown in Figure 15, every N=3 transmission periods starting from transmission time 0 (ie 5ms), groupPeriodicity={T21, T22, T23} takes effect once, so compared to the transmission process shown in Figure 5 without groupPeriodicity 15 , in every N=3 transmission cycles starting from transmission time 1, the first transmission cycle becomes T21, the second transmission cycle becomes T22, and the third transmission cycle becomes T23. The sum of N consecutive transmission periods included in groupPeriodicity is equal to the sum of N arrival periods, that is, T21+T22+T23=N×T1. For example, the first N=3 transmission periods that have passed since transmission time 0 (ie, 5ms), the transmission period between transmission opportunity 0 and transmission opportunity 1 is T21=8.4ms, and the transmission period between transmission opportunity 1 and transmission opportunity 2 is T21=8.4ms. The transmission period is T22=8.4ms, and the transmission period between transmission opportunity 2 and transmission opportunity 3 is T23=8.2ms. T21+T22+T23=8.4+8.4+8.2=25ms=N×T1=3×8.33. Moreover, due to the change in the periodic interval, the transmission time 1 is no longer the time after transmission time 0 (ie 5ms) after 8ms (ie 5+8=13ms), but the time after T21 after transmission time 0 (ie 5ms). +8.4=13.4ms). Similarly, the transmission time 2 is also the time T22 after the transmission time 1 (ie 13.4+8.4=21.8ms), and the transmission time 3 is also the time after the transmission time 2 and the time T23 (ie 21.8+8.2=30ms). For the value of N, reference may be made to the description of FIG. 9 above, and details are not repeated here.

Optionally, N consecutive transmission periods represented by groupPeriodicity may constitute a new period: the preset period T0=T21+T22+T23=8.4+8.4+8.2=25ms. The preset period may include N continuous transmission periods represented by groupPeriodicity, and the values of the N continuous transmission periods may be the same or different, and the specific values are not limited. The preset period may include N consecutive transmission periods, that is, N+1 transmission moments have passed. Wherein, the start time of the preset period is the transmission time that arrives first in the above-mentioned N+1 transmission times, and the end time is the transmission time that arrives last in the above-mentioned N+1 transmission times. For example, for the first preset period starting from the initial time 0, the starting time is the transmission time 0 (ie 5ms), that is, the time when the initial time 0 passes the first offset offset1 (ie 5ms); the end time is the transmission time 3 (ie 30ms) can also be understood as the time T21+T22+T23=8.4+8.4+8.2=25ms (ie 5+25=30ms) after the above starting time (ie 5ms).

Comparing Figure 5 and Figure 15, it can be seen that although the XR data packets are all jittered and the first offset offset1 remains unchanged, Figure 15 introduces T21, T22 and T23. Therefore, compared with Fig. 5, the transmission opportunity 6 in Fig. 15 is not wasted, and the transmission delay of the data packet 6 (55-53.5=1.5ms), the transmission delay of the data packet 7 (63.4-61.2=2.2ms), The transmission delay of packet 8 (71.8-69.5=2.3ms) and the transmission delay of packet 9 (80-77.5=2.5ms) are both small, thereby reducing the impact of XR packet jitter (that is, transmission The opportunity is wasted, the transmission delay is large), and the user experience is better.

Not limited to the cases listed above, T21, T22, and T23 may also have other values, for example, the values in FIG. 13 are 18ms, 15ms, 17ms, etc. The value is not limited, but the sum of the N consecutive transmission periods is required to be N×T1.

Not limited to the cases listed above, in the specific implementation, N can also have other values. For example, in Figure 13 above, N can also take the value of an integer multiple of 6, 9, etc. 3, or any one of 2, 4, 5, etc. positive integer. Or, when the frequency of the XR service is 90Hz, the arrival period T1 is 11.11ms, and N is an integer multiple of 9, 18, etc. (9×11.11=100ms, that is, the sum of 9 arrival periods is an integer), or 1, 3, 6, 10, etc. any positive integer. This application does not limit the value manner of N.

In the transmission process shown in the third embodiment, the transmission period is independently configured for each transmission opportunity in every N consecutive transmission periods by introducing a period group (groupPeriodicity), so as to realize the matching between the transmission period and the arrival period. In addition, combined with the introduction of a new transmission period value, adjusting the existing initial offset further reduces the impact of XR packet jitter, avoids wasting transmission opportunities, reduces transmission delay, and provides a better user experience.

The above description takes the sending device sending data based on the configured transmission period as an example, but it can be understood that the receiving device will also receive data based on the above transmission period after negotiating the above transmission period with the transmitting device.

It is not limited to the XR data packets of the XR services listed above. In the specific implementation, the data to be transmitted can also be the data of other services that arrive periodically, and can also be the data of other services that arrive aperiodically. Not limited.

It is not limited to the above-mentioned unit of transmission period and transmission time (that is, ms). In a specific implementation, the unit can also be a symbol. For example, when the subcarrier interval is 15 kilohertz (kHz), 14 can be transmitted in 1 ms. symbol, so the first cycle interval in Figure 15 above is 8ms, which can be understood as the first cycle interval of 8 × 14 symbols, and the transmission time 0 in Figure 15 above is 5ms, which can be understood as the position of the transmission time 0. The position where the 5×14 symbols are located, which may also be referred to as the starting symbol of transmission time 0, is the 5×14th symbol. When the sub-carrier spacing is 30 kHz, 2 × 14 symbols can be transmitted in 1 ms, and when the sub-carrier spacing is 60 kHz, 4 × 14 symbols can be transmitted in 1 ms. The unit conversion process of the transmission period and transmission time is consistent with the above-mentioned sub-carrier spacing of 15 kHz. ,No longer. Alternatively, the unit may also be a time slot (slot), and this application does not limit the specific unit.
