[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0038] Communication system architecture

[0039] The following describes a communication system applicable to an embodiment of the present application by taking FIG1 as an example.

[0040] As shown in Figure 1, communication system 10 may include base station 101, base station 102, base station 105, terminal device 103, and terminal device 104. Communication system 10 is a dual connectivity architecture, where base station 101 is a primary base station, and base stations 102 and 105 are secondary base stations.

[0041] The base station in Figure 1 can be any device with wireless transceiver capabilities, including but not limited to: an evolutionary Node B (NodeB, eNB, or e-NodeB) in long term evolution (LTE), a gNodeB or gNB or a transmission receiving point (TRP) in new radio (NR), and subsequent evolutions of the Third Generation Partnership Project (3GPP). A base station can be: a macro base station, a micro base station, a pico base station, a small base station, a relay station, or a balloon base station. Multiple base stations can support networks using the same technology mentioned above, or networks using different technologies mentioned above. A base station can include one or more co-located or non-co-located TRPs. A base station can also be a radio controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. A base station can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move according to the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0042] The terminal device in Figure 1 is a device with wireless transceiver function, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (for example, on airplanes, balloons and satellites, etc.). The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a terminal in industrial control, a vehicle-mounted terminal device, a terminal device in self-driving, a terminal device in assisted driving, a terminal device in remote medical care, a terminal device in a smart grid, a terminal device in transportation safety, a terminal device in a smart city, a terminal device in a smart home, etc. The embodiments of the present application do not limit the application scenarios. Terminal equipment may also be sometimes referred to as terminal, user equipment (UE), access terminal, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal device, wireless communication device, machine terminal, UE agent, or UE device. Terminals can be fixed or mobile.

[0043] As an example and not a limitation, in the embodiments of the present application, the terminal device may be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0044] XR services and their resource scheduling

[0045] XR is considered a technology with great potential. The optimal form and development trend of promoting large-scale XR applications will become one of the typical applications of future communications. Therefore, supporting XR services in wireless communication systems is a key aspect of system design.

[0046] The types of XR may include one or more of the following: augmented reality (AR), mixed reality (MR), virtual reality (VR), etc.

[0047] High data rates are a key characteristic of XR services. With the continuous development of wireless cellular communication technologies, particularly 5G, spectrum efficiency is increasing, available frequency bands are becoming wider, and transmittable data rates are increasing. This makes it increasingly feasible to support XR services using cellular communication technologies. However, XR services, with their large data volumes, place stringent requirements on transmission latency. Therefore, to minimize latency in XR service transmission, base stations must be informed of relevant XR service parameters to help them determine more appropriate scheduling strategies.

[0048] XR service parameters can be categorized into four categories: data volume, latency, timing, and other parameters. Data volume parameters may include average data volume and maximum data volume, while latency parameters may include maximum allowable latency. Timing parameters may include the timing, period, and jitter range of data arrival at the access layer. Other parameters include protocol data unit (PDU) set importance parameters.

[0049] For the above four types of parameters, data volume related parameters, delay related parameters and other parameters can be notified to the base station by the core network control network element without the need for transmission on the wireless interface.

[0050] Among the timing-related parameters, the period depends on the characteristics of the XR service, such as the sampling rate, so the period usually does not change over time. Therefore, the period can also be notified to the base station by the core network control network element. The timing of data arrival at the access layer can be divided into two categories: the timing of uplink (UL) data arriving at the access layer of the terminal device and the timing of downlink (DL) data arriving at the access layer of the base station. Currently, 3GPP has decided that the timing of uplink data arriving at the access layer of the terminal device is reported to the base station by the terminal device through the UAI message; the timing of downlink data arriving at the access layer of the base station has not yet been determined by which network element to notify the base station. As for the jitter range, the jitter range of uplink data depends on the encoding speed of each video frame by the XR encoder inside the terminal, so it can only be notified to the base station by the terminal device; the jitter range of downlink data depends on the encoding speed of the server side and the link required for data transmission from the XR server to the base station, so it can also be notified to the base station by the network device.

[0051] As can be seen from the above, among the relevant parameters of XR services, the timing of uplink data reaching the access layer and the jitter range can be notified to the base station by the terminal device through a UAI message. The following uses Figure 2 to illustrate the process of UAI messages.

[0052] Referring to Figure 2, the process of a terminal device reporting a UAI message to a base station may include steps S210-S230. In step S210, the base station sends an RRC reconfiguration request message to the terminal device. The RRC reconfiguration request is used to configure radio resources for the terminal device. In step S220, the terminal device sends an RRC reconfiguration complete message to the base station. The RRC reconfiguration complete message is used to notify the base station that the RRC reconfiguration process is complete. After the RRC reconfiguration process is completed, the terminal device determines whether to report a UAI message. If so, the terminal device reports the UAI message to the base station as shown in step S230.

[0053] After receiving the UAI message from the terminal device, the base station can perform secondary configuration of radio resources for the XR service based on the relevant parameters of the XR service in the UAI message. For example, the base station indicates to the terminal device through secondary configuration the specific time domain location of the radio resources used to transmit the XR service. Taking Figure 3 as an example, after the terminal device completes the UAI reporting process, it can continue to execute steps S310-S330.

[0054] In step S310 , the base station modifies the radio configuration related to the XR service.

[0055] In step S320, the base station sends an RRC reconfiguration request message to the terminal device, which includes the modified radio configuration related to the XR service.

[0056] In step S330, the terminal device sends an RRC reconfiguration completion message to the base station, indicating that the reconfiguration process is completed.

[0057] Reporting of UAI messages in dual-connection scenarios

[0058] In the dual-connectivity scenario shown in Figure 1, the terminal device is configured with a primary base station and a secondary base station, corresponding to the master cell group (MCG) and secondary cell group (SCG), respectively. When reporting a UAI message, the terminal device can report it to the base station corresponding to the primary cell group or the secondary cell group, that is, to the primary base station or the secondary base station. The following describes the UAI message reporting process in the dual-connectivity scenario in conjunction with Figure 4.

[0059] 4 , in step S410 , it is determined whether the parameters triggering the terminal device to report UAI are related to the SCG, if so, the process proceeds to step S420 , otherwise, the process proceeds to step S430 .

[0060] In step S420, it is determined whether the signaling radio bearer 3 (SRB3) of the SCG is in an active state. If the SRB3 of the SCG is in an active state, the process proceeds to step S440; otherwise, the process proceeds to step S450.

[0061] In step S430, the terminal device reports a UAI message to the base station corresponding to the MCG.

[0062] In step S440, the terminal device reports a UAI message to the base station corresponding to the SCG.

[0063] In step S450, the terminal device reports a UAI message to the base station corresponding to the MCG, and the primary base station then transparently transmits the message to the secondary base station.

[0064] However, when the terminal device reports the parameters related to the XR service through the UAI message, the terminal device does not know whether the XR service is configured in the MCG or SCG, resulting in the terminal device not knowing which base station to report the UAI message to. If the understanding of the terminal device and the base station is inconsistent, communication confusion may occur. For example, the MCG configures wireless resources for the XR service, but does not clearly indicate which XR service the wireless resources are used to transmit. The terminal device may report the UAI message of the XR service to the SCG, and the MCG will not be able to adjust the wireless resources of the XR service in time according to the UAI message.

[0065] Based on the above problems, the embodiments of the present application are described in detail below.

[0066] Example 1

[0067] FIG5 is a flow chart of a wireless communication method provided in Embodiment 1 of the present application. The method in FIG5 can be executed by a terminal device configured with an MCG and an SCG.

[0068] 5 , in step S510 , a terminal device sends a first message to a first base station. The first message includes first information associated with a first XR service.

[0069] In some implementations, the first information may be a parameter associated with the first XR service.

[0070] In some implementations, the first message may be a UAI message.

[0071] In some implementations, the first base station is a primary base station corresponding to the primary cell group, such as the base station 101 shown in FIG1 .

[0072] In some implementations, the first base station is a secondary base station corresponding to the secondary cell group, such as the base station 102 or the base station 105 shown in FIG1 .

[0073] In some implementations, the first base station is a primary base station and a secondary base station, that is, the terminal device sends the first message to both the primary base station and the secondary base station.

[0074] The method shown in FIG5 clarifies the base station to which the terminal device reports service-related parameters in a dual-connection scenario, thereby helping to avoid communication confusion.

[0075] In some implementations, the first base station is a base station corresponding to a first resource parameter. The first resource parameter may be used to transmit a first XR service.

[0076] In some implementations, the first resource parameter may be a CG resource parameter.

[0077] In some implementations, the association between the first resource parameter and the first XR service is based on an RRC reconfiguration message indication. For example, the primary base station or the secondary base station may configure one or more sets of uplink resource parameters in the RRC reconfiguration message, and indicate the association between the one or more sets of uplink resource parameters and one or more XR services (i.e., indicating which set of uplink resource parameters is configured for which XR service).

[0078] In some implementations, the terminal device may determine the first base station based on the association relationship between the first resource parameter indicated in the RRC reconfiguration message and the first XR service. For example, after determining that the first XR service corresponds to the first resource parameter, the terminal device may determine whether the first resource parameter corresponds to the primary base station (or MCG) or the secondary base station (or SCG). If the first resource parameter corresponds to the primary base station, the terminal device may send the first message to the primary base station (in this case, the first base station mentioned above is the primary base station); if the first resource parameter corresponds to the secondary base station, the terminal device may send the first message to the secondary base station (in this case, the first base station mentioned above is the secondary base station).

[0079] In some implementations, if only one of the primary base station and the secondary base station is configured with CG resource parameters, the first base station is the base station configured with CG resource parameters among the primary base station and the secondary base station. In the case where only one base station is configured with CG resource parameters, the terminal device may default to the base station configured with CG resource parameters to be used to transmit the first XR service, so the terminal device may directly send the first message (including the first XR-related parameters) to the base station configured with the CG resource parameters.

[0080] In some implementations, the first base station determines based on the second information sent by the main base station, and the second information is used to indicate that the first XR service is configured in the main cell group; or, the first base station determines based on the second information sent by the main base station, and the second information is used to indicate that the first XR service is configured in the secondary cell group; or, the first base station determines based on the second information sent by the secondary base station, and the second information is used to indicate that the first XR service is configured in the main cell group; or, the first base station determines based on the second information sent by the secondary base station, and the second information is used to indicate that the first XR service is configured in the secondary cell group. For example, if the second information indicates that the first XR service will be configured in the MCG, the terminal device can determine that the first base station is the main base station corresponding to the MCG, and send a first message to the main base station. For another example, if the second information indicates that the first XR service will be configured in the secondary cell group, the terminal device can determine that the first base station is the secondary base station corresponding to the secondary cell group, and send a first message to the secondary base station.

[0081] In some implementations, if the first XR service is configured in a secondary cell group and the secondary cell group is in an inactive state (the inactive state of the secondary cell group may mean that the SRB3 of the secondary cell group is inactive), the first message is transparently transmitted to the secondary base station through the primary base station. For example, when the above-mentioned second information indicates that the first XR service is configured in a secondary cell group and the secondary cell group is inactive, the terminal device can send the first message to the primary base station, which is transparently transmitted to the secondary base station via the primary base station. In this way, the delay in sending the first message due to the secondary cell group being in an inactive state can be avoided.

[0082] In some implementations, the second information is carried in an RRC message, a medium access control control element (MAC CE), a packet data convergence protocol (PDCP) control PDU, or an application layer message.

[0083] In some implementations, the second information occupies one or more bits, and the one or more bits include a first value and a second value, where the first value is used to indicate that the first XR service is configured in a primary cell group (or primary base station), and the second value is used to indicate that the first XR service is configured in a secondary cell group (or secondary base station). For example, the second information can be a Boolean variable with a first value of 0 and a second value of 1. When the value of the second information is 0, it indicates that the first XR service is configured in an MCG; when the value of the second information is 1, it indicates that the first XR service is configured in an SCG.

[0084] In some implementations, if the terminal device is configured with multiple secondary cell groups, the second information is also used to indicate the target secondary cell group in which the first XR service is configured among the multiple secondary cells (i.e., clearly indicating which secondary cell group in which the first XR service is configured), and the first base station is the base station corresponding to the target secondary cell group.

[0085] In some implementations, if there are multiple XR services, the second information may also be used to indicate in which cell group each XR service is configured. For example, the second information indicates that the first XR service is configured in the primary cell group and the second XR service is configured in the secondary cell group. The terminal device may send parameters related to the first XR service to the base station corresponding to the primary cell group through the first message, and send parameters related to the second XR service to the base station corresponding to the secondary cell group.

[0086] In some implementations, the first base station may be determined based on the implementation of the terminal device. That is, the terminal device may autonomously determine whether to send the first message to the primary base station or to the secondary base station based on actual needs. For example, the terminal device may autonomously decide whether to send the first message to the primary base station, to the secondary base station, or to both the primary base station and the secondary base station.

[0087] In some implementations, the first base station may be determined based on protocol provisions.

[0088] In some implementations, the first base station corresponds to a cell group with a larger cell bandwidth in the primary cell group and the secondary cell group. The cell group with a larger bandwidth can support a higher transmission rate and is more suitable for transmitting XR services.

[0089] In some implementations, the first base station corresponds to a cell group in frequency range 2 (FR2) in the primary cell group and the secondary cell group. For example, if the primary cell group is in frequency range 2, the primary base station can be used as the first base station to send the first message to the primary base station. For another example, if the secondary cell group is in frequency range 2, the secondary base station can be used as the first base station to send the first message to the secondary base station. FR2 cells have a larger bandwidth and a higher transmission data rate, making them more suitable for transmitting XR services.

[0090] In some implementations, the first message includes third information. The third information is used to indicate that the terminal device prefers to transmit the first XR service through the primary base station or the secondary base station. For example, the terminal device can indicate to the first base station through the third information that it prefers to transmit the first XR service through the MCG (or primary base station). The introduction of the third information helps the base station configure or schedule the transmission of the first XR service according to the preferences of the terminal device. Furthermore, if there are multiple first XR services, the terminal device can also indicate through the third information which of the primary base station or the secondary base station it prefers to transmit the XR service through.

[0091] In some implementations, the first information (i.e., parameters related to the first XR reported to the base station via UAI) may include one or more of the following: the timing when the uplink data arrives at the access layer of the terminal device; and the jitter time range of the uplink data.

[0092] In some implementations, the timing of the arrival of downlink data at the access layer of the base station can be notified to the base station by the core network or the XR server, instead of being reported through the first message. However, the core network and the XR server do not know the correspondence between the wireless frame number and the subframe number on the base station side. If the core network and the XR server notify the time when the downlink data arrives at the base station access layer, they can only use absolute time notification, that is, the common time value of both parties. This requires the base station and the XR server to maintain synchronized clocks, which is a relatively high requirement. In addition, a base station may transmit XR service-related parameters from multiple XR servers. The clocks of these XR servers are different. The terminal device needs to maintain the clocks of multiple XR servers, which is more complicated.

[0093] Therefore, in some other implementations, the first information may also include the timing when the downlink data arrives at the access layer of the base station. In other words, the timing when the downlink data arrives at the access layer of the base station may also be reported by the terminal device.

[0094] In some implementations, the first information may use the system frame number (SFN) number, subframe number, symbol sequence number, etc. of the cell to indicate the timing when the uplink data arrives at the access layer of the terminal device and / or the timing when the downlink data arrives at the access layer of the base station. The cell may be a cell in the cell group to which the terminal device reports the first information, such as a primary cell (PCell), or other cells in the cell group. For example, if the terminal device reports the first information to the MCG, the cell refers to a cell within the MCG. However, if the terminal device intends to report the first information to the SCG and forward the first information to the MCG via the SCG, and the final XR service is still transmitted through the MCG, then the cell is a cell in the MCG. For another example, if the terminal device reports the first information to the SCG, then the cell refers to a cell within the SCG. However, if the SCG has not yet been activated, the terminal device intends to report the first information to the MCG and forward the first information to the SCG via the MCG, and the final XR service is still transmitted by the SCG, then the cell is a cell in the SCG.

[0095] In some implementations, the first information may also use absolute time to indicate the timing when uplink data arrives at the access layer of the terminal device and / or the timing when downlink data arrives at the access layer of the terminal device.

[0096] In other implementations, the first information may also use relative time to indicate the timing when the uplink data arrives at the access layer of the terminal device and / or the timing when the downlink data arrives at the access layer of the terminal device. For example, the relative time may be the time difference between the time when the first information is sent and the time when the uplink data (or downlink data) arrives at the access layer of the terminal device.

[0097] Example 2

[0098] The previous text describes the secondary configuration process of the XR service in conjunction with Figure 3. The secondary configuration process of the XR service is relatively complex and may cause waste of resources. In response to the above problems, the following text describes the second embodiment of the present application in detail with reference to Figure 6.

[0099] Figure 6 is a flow chart of a wireless communication method provided in Embodiment 2 of the present application. The method in Figure 6 can be applied to common communication scenarios, and can also be applied to the dual-connection scenario shown in Figure 1 .

[0100] Referring to Figure 6, in step S610, the terminal device receives an RRC reconfiguration message sent by the base station. The RRC reconfiguration message includes a first CG resource parameter, which is used to transmit the first XR service, and the first CG resource parameter does not include the time domain offset value (or time domain offset parameter) of the first CG resource. That is, the base station can indicate to the terminal device through the RRC reconfiguration message that the first CG resource is a CG resource configured for the first XR service, but does not indicate the time domain offset value of the first CG resource.

[0101] In step S620a, the terminal device determines the time domain offset value of the first CG resource according to the timing when the service data of the first XR service arrives at the access layer.

[0102] In some implementations, the terminal device may determine the time domain offset value of the first CG resource based on a predefined rule according to the timing when the service data of the first XR service arrives at the access layer. For example, when the period of the first CG resource is 16ms, the frame and subframe information of the timing when the uplink data arrives at the access layer is: SFN = 0, subframe number = 6 (see 710 in Figure 7), the terminal device may determine that the time domain offset value of the first CG resource is 6.

[0103] In step S620b, the base station determines the time domain offset value of the first CG resource according to the timing when the service data of the first XR service arrives at the access layer. The base station can determine the time domain offset value of the first CG resource in a similar manner to the terminal device, which will not be repeated here.

[0104] In the second embodiment of the present application, the terminal device and the base station can independently determine the time domain offset value of the CG resource corresponding to the XR service, thereby eliminating the need for secondary configuration. This can simplify the secondary configuration process of the XR service and avoid waste of resources.

[0105] In some implementations, after receiving the RRC reconfiguration message, the terminal device may send an RRC reconfiguration complete message to the base station.

[0106] In some implementations, as shown in FIG8 , the method further includes step S820. In step S820, the terminal device sends a UAI message to the base station. The UAI message includes first information indicating a timing when service data of the first XR service arrives at the access layer. The timing when the service data of the first XR service arrives at the access layer in step S620b can be determined by the base station using the first information.

[0107] In some implementations, the first information is used to indicate one or more of the following: a timing when uplink data arrives at an access layer of a terminal device; a timing when downlink data arrives at an access layer of a base station.

[0108] The following describes in more detail the wireless communication method provided in the second embodiment of the present application in conjunction with the specific examples in Figures 9A and 9B. It should be noted that the examples in Figures 9A and 9B are merely intended to help those skilled in the art understand the embodiments of the present application, and are not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. Based on the examples of Figures 9A and 9B given, those skilled in the art can obviously make various equivalent modifications or changes, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0109] As shown in Figure 9A, in step S910, the base station sends an RRC reconfiguration message to the terminal device. The RRC reconfiguration message configures the first CG resource for the first XR service, but does not indicate the time domain offset value of the first CG resource (assuming that the first CG resource period is 16ms).

[0110] In step S920, the terminal device sends an RRC reconfiguration completion message to the base station to indicate the completion of the RRC reconfiguration process.

[0111] It should be noted that, in the related art, the configuration of the CG resource takes effect after the terminal device sends the RRC reconfiguration completion message to the base station. Unlike the related art, in the embodiment of the present application, after the terminal device sends the RRC reconfiguration completion message to the base station, the configuration of the first CG resource has not yet taken effect. It needs to wait until the terminal device reports the UAI message to the base station and determines the time domain offset value of the first CG resource before it takes effect (see steps S930 to S940).

[0112] In step S930 , the terminal device reports a UAI message to the base station to indicate a timing when uplink data of the first XR service arrives at the access layer.

[0113] In step S940a and step S940b, the terminal device and the base station respectively determine the time domain offset value of the first CG resource.

[0114] For example, assuming that the timing when the uplink data arrives at the access layer is the time domain position pointed to by the reference mark 910 in Figure 9B, that is, the time domain position of system frame number SNF=0 and subframe number=6, then the time domain offset value of the first CG resource can be determined to be 6.

[0115] For example, the timing when the uplink data arrives at the access layer is the time domain position pointed to by the reference mark 920 in Figure 9B, that is, the time domain position of system frame number SNF=1 and subframe number=9. Then, by moving forward one cycle (16ms) from this moment, the time domain offset value of the first CG resource is determined to be 3.

[0116] Example 3

[0117] As mentioned above, after the terminal device sends a UAI message to the base station, the base station adjusts the resources used to transmit the first XR service based on the first information in the UAI message. However, if the terminal device frequently reports the first information to the base station, it may cause a waste of wireless resources.

[0118] Based on the above problems, the present application provides another wireless communication method.

[0119] The wireless communication method provided in Example 3 of the present application is described in detail below with reference to FIG10 . The method includes step S1010. In step S1010, a terminal device receives configuration parameters sent by a base station. The configuration parameters are used to configure an inhibit timer, which is used to inhibit the reporting of first information. For example, while the inhibit timer is running, the terminal device is prohibited from reporting the first information to the base station. After the inhibit timer expires, the terminal device can report the first information to the base station. Configuring the inhibit timer when reporting a UAI message by the terminal device helps avoid frequent reporting of the first information to the base station by the terminal device, which wastes radio resources. If the content reported in the UAI message comes from the application layer of the terminal device, and the application layer is unaware of the configuration of the inhibit timer by the base station, it is possible that the application layer frequently notifies the access layer of modifications to the first information, while the access layer is unable to report. Therefore, in some implementations, the terminal device sends indication information to the application layer of the terminal device, indicating the value of the inhibit timer. Notifying the application layer of the value of the inhibit timer can avoid frequent notification of the first information by the application layer.

[0120] In some implementations, the method of FIG. 10 further includes: if the base station reconfigures resource parameters for the XR service, the terminal device sending a first UAI message to the base station, and the sending of the first UAI message ignores the prohibit timer. For example, if the base station changes the bearer of an XR service from an SCG to an MCG, the terminal device reports the first UAI message to the base station regardless of whether the prohibit timer has expired.

[0121] In some implementations, the prohibition timer includes a first prohibition timer and a second prohibition timer, the first prohibition timer is used to prohibit reporting of the first information, and the second prohibition timer is used to prohibit reporting of the second parameter, the first information is used to indicate the timing when the uplink data of the XR service arrives at the access layer of the terminal device, and the second parameter is used to indicate the timing when the downlink data of the XR service arrives at the access layer of the base station. The update frequency of the first information and the second parameter may be different, wherein the update frequency of the first information mainly depends on the encoding and source on the terminal device side, and the update frequency of the second parameter mainly depends on the encoding speed of the source encoder and the delay required for data to be transmitted from the XR application server to the base station. Therefore, when the terminal device reports to the base station through the UAI message at the same time the timing when the uplink data arrives at the access layer of the terminal device and the timing when the downlink data arrives at the access layer of the base station, these two parameters can use two independent prohibition timers to increase flexibility.

[0122] As an example, the size relationship between the values ​​of the first prohibition timer and the second prohibition timer can be shown in Figure 11, where T1 is the moment when the terminal device reports the UAI message to the base station, and the UAI message includes the timing when the uplink data of the XR service arrives at the access layer of the terminal device and the timing when the downlink data of the XR service arrives at the access layer of the base station. T2 is the value of the first prohibition timer, and T3 is the value of the second prohibition timer. Then the terminal device can report the timing when the uplink data of the XR service arrives at the access layer of the terminal device again after T2, and can report the timing when the downlink data of the XR service arrives at the access layer of the base station again after T3. Therefore, in the interval between T2 and T3, the terminal device can report to the base station again the timing when the uplink data arrives at the access layer of the terminal device. In this way, the utilization rate of the XR service transmission resources is increased, making the transmission of the XR service more flexible.
