[0044] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the present disclosure will be further described in detail below with reference to the drawings and embodiments. It can be understood that the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. The specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0045] It should be noted that in this document, relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any such actual relationship or order between such entities or actions.

[0046] In the related art, the fifth generation mobile communication technology (5G) user plane air interface protocol stack is shown in FIG. 1, including: SDAP (Service Data Adaptation Protocol) layer, PDCP (Packet Data Convergence Protocol) layer, RLC (Radio Link Control) layer, MAC (Media Access Control) layer and PHY (Physical Layer).

[0047] When a QoS flow (Quality of Service flow) arrives at the SDAP layer, the SDAP layer performs mapping of the QoS flow to a DRB (Data Radio Bearer), and forms an SDAP PDU (Protocol Data Unit) after the mapping. The SDAP PDU is a PDCP SDU (Service Data Unit). The PDCP layer performs operations such as header compression and encryption on the PDCP SDU, and then delivers the PDCP SDU to the RLC layer. The RLC layer then encapsulates an RLC PDU according to MAC layer scheduling information, and delivers the RLC PDU to the MAC layer. The MAC layer encapsulates the received RLC PDU into a MAC PDU, and then delivers the MAC PDU to the PHY layer for transmission.

[0048] The principle of mapping of the QoS flow to the DRB by the SDAP layer is as follows: since the QoS attributes of the data packets in a QoS flow are basically the same, a QoS flow can only be mapped to one DRB. Each DRB maps data to the RLC layer, and the RLC layer transmits the data to the MAC layer. The MAC layer sees the data packets from the RLC layer. The RLC layer sends each data associated with a DRB to the MAC layer through a data channel. The data channel between the RLC layer and the MAC layer is a logical channel.

[0049] The MAC layer is responsible for performing scheduling on the data packets of each logical channel from the upper layer (i.e., the RLC layer). When scheduling, the MAC layer is responsible for sorting the relevant data according to the priority of the logical channel of the data, and sending the data to the uplink resource.

[0050] Therefore, the functions of the MAC layer include the following two parts:

[0051] (1) Configuration of mapping restrictions of logical channels, and selection of logical channels;

[0052] (2) Resource allocation.

[0053] For the configuration of mapping restrictions of logical channels in (1), the RRC (Radio Resource Control) layer in the 5G control plane air interface protocol stack configures the following at least one piece of information for each logical channel: priority, Prioritised Bit Rate (PBR), Bucket Size Duration (BSD), and the like.

[0054] The RRC layer configures mapping restrictions for each logical channel, i.e., based on the current uplink resource, only the data of the logical channel whose mapping restriction and the uplink resource match can be transmitted on the current uplink resource.

[0055] For example, for a specific uplink resource, if the logical channel is configured with an allowedSCS-List, then if the subcarrier spacing of the uplink resource is within the list, the data in the logical channel can be further transmitted on the uplink resource based on subsequent resource allocation steps.

[0056] Therefore, it is necessary to select a logical channel based on the configuration of the mapping restriction of the logical channel, i.e., if the logical channel is configured with a mapping restriction, only when the mapping restriction is met, the logical channel can be selected to participate in the current uplink resource allocation; if no mapping restriction is configured, the logical channel can be directly selected to participate in the current resource allocation.

[0057] For the resource allocation in (2), the uplink resource allocated by the base station to the terminal is for one user. In order to guarantee the fairness between different services in the uplink transmission of the terminal and avoid that some services have no uplink resource, the resource allocation mechanism based on logical channel priority (LCP) and priority-based bit rate (PBR) is currently used.

[0058] The resource allocation mechanism based on LCP and PBR is as follows 1 to 3:

[0059] 1. When the terminal obtains an uplink resource grant (UL grant), for the logical channel whose token number in the token bucket is greater than zero (Bj>0), the first round of resource allocation is performed according to the PBR for each logical channel with data transmission demand in descending order of logical channel priority.

[0060] 2. After the first round of resource allocation is completed, Bj of each logical channel is updated as Bj minus the data packet size of all MAC SDUs allocated to the logical channel in the first round of resource allocation.

[0061] 3. If there is still remaining resource after the first round of resource allocation is completed, the second round of resource allocation is performed for each logical channel in descending order of the priority of the logical channel with data transmission demand (without considering the principle of Bj>0).

[0062] In addition, the 5G system introduces an extended reality (XR) service, which is divided into three categories: an augmented reality (AR) service, a virtual reality (VR) service, and a mixed reality (MR) service.

[0063] The XR service is modeled according to a data frame, and the same data frame can be divided into a plurality of packet data units (PDUs). FIG. 2 is a schematic diagram of a data frame of an XR service, in which the definition of a PDU set is as follows: one or more PDUs corresponding to one information unit (slice / tile) form a PDU set.

[0064] The XR service supports multi-modal, in which a plurality of high-layer service streams of one user terminal need to be coordinated and transmitted with certain synchronization requirements when transmitted over the air. In addition, the XR service also has a strong latency constraint requirement.

[0065] The related art only considers the priority of a logical channel (LCP) and a priority-based bit rate (PBR) when performing logical channel selection and uplink resource allocation, but the XR service has a latency requirement, and the related art cannot meet the latency requirement of the XR service, nor can it guarantee the transmission of high-priority services.

[0066] FIG. 3 is a flowchart of an uplink logical channel selection method provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 3, the uplink logical channel selection method can include, but is not limited to, steps 301 and 302:

[0067] In step 301, configuration information sent by a network device is obtained, and the configuration information includes a semi-static resource for sending first data.

[0068] The semi-static resource includes:

[0069] The semi-static resource for sending latency-critical data, and / or the semi-static resource for sending data in a logical channel carrying latency-critical data, and / or a dedicated semi-static resource for sending data in a logical channel carrying latency-critical data.

[0070] It should be noted that the semi-static resource for sending latency-critical data may not have latency-critical data in the data sent in the process of sending data. The data sent in the logical channel carrying latency-critical data can not include latency-critical data, or can include latency-critical data.

[0071] The delay-critical data is data corresponding to data packets in a logical channel whose remaining delay is less than a preset delay threshold, or the delay-critical data is data corresponding to data packets in a data packet set in a logical channel, at least one data packet in the data packet set having a remaining delay less than a preset delay threshold; wherein the preset delay threshold is a threshold configured by a network device or a threshold agreed by a protocol.

[0072] In this embodiment, the logical channel carrying the delay-critical data is, for example, a logical channel configured to use a dedicated logical channel priority when there is delay-critical data.

[0073] In some embodiments, the first data can be XR service data or other service data. If the first data is XR service data, the semi-static resource for transmitting the XR service data includes:

[0074] The semi-static resource for transmitting the XR service delay-critical data, and / or the dedicated semi-static resource for transmitting the XR service data, and / or the semi-static resource for transmitting the delay-critical data and non-delay-critical data in the logical channel carrying the XR service delay-critical data.

[0075] In this embodiment, the configuration information includes at least one of the following (1) to (3):

[0076] (1) Configure Grant (CG) resource.

[0077] (2) Index information of the CG resource.

[0078] (3) First indication information, used to indicate a CG resource for preferentially transmitting delay-critical data, a CG resource for transmitting data in a logical channel carrying delay-critical data, or a CG resource for transmitting data having a synchronization transmission requirement.

[0079] The CG resource is the semi-static resource for transmitting the first data.

[0080] In some embodiments, the configuration information can further include a dynamic resource for transmitting the first data.

[0081] In step 302, based on the constraint condition of the semi-static resource, an uplink logical channel satisfying the constraint condition is selected.

[0082] In this embodiment, the constraint condition includes at least one of the following:

[0083] (1) There is delay-critical data in the uplink logical channel of the terminal;

[0084] (2) The data existing in the uplink logical channel of the terminal is data with a synchronous transmission requirement.

[0085] For example, the constraint condition specifically includes at least one of the following (A) to (E):

[0086] (A) The remaining latency of the data existing in the uplink logical channel of the terminal is less than a preset latency threshold, and the preset latency threshold is a threshold configured by the network device or a threshold agreed by a protocol.

[0087] (B) The uplink logical channel of the terminal has latency-critical data.

[0088] (C) The mapping restriction of the uplink logical channel of the terminal is configured with allowed identification or index information of a semi-static resource.

[0089] (D) The mapping restriction of the uplink logical channel of the terminal is configured with allowed identification of latency-critical data.

[0090] (E) The data existing in the uplink logical channel of the terminal is data with a synchronous transmission requirement.

[0091] For example, the constraint condition can also be that the configured uplink grant resource is configured with allowed use identification of a logical channel with latency-critical data. This constraint condition is used in combination with at least one of the above constraint conditions (A) to (E).

[0092] In some embodiments, when the uplink logical channel satisfying the constraint condition is selected, the uplink logical channel satisfying the constraint condition can be selected in descending order of the priority of the uplink logical channel.

[0093] It can be seen that after the uplink logical channel satisfying the constraint condition is selected, the at least one uplink logical channel selected or the data in the at least one uplink logical channel selected allows use of the configured information, for example, the semi-static resource for transmitting the first data in the allowed use configuration information. The terminal can transmit the data in the at least one uplink logical channel selected on the semi-static resource for transmitting the first data, and / or transmit the first data on the semi-static resource for transmitting the first data. The terminal can also use the at least one uplink logical channel selected for the uplink resource allocation process.

[0094] Therefore, by obtaining the configuration information sent by the network device, the configuration information including the semi-static resource for sending the first data, and then selecting the uplink logical channel satisfying the constraint condition, the constraint condition can consider the delay requirement and / or the synchronization transmission requirement, so that the selected at least one uplink logical channel can transmit the delay urgent data and / or the data (for example, high priority service data) with the synchronization transmission requirement using the semi-static resource for sending the first data, and the delay urgent data transmission delay requirement is met while the synchronization transmission of the high priority service data is guaranteed.

[0095] FIG. 4 is a flow diagram of an uplink resource allocation method provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 4, the uplink resource allocation method can include but is not limited to steps 401 and 402:

[0096] In step 401, the priority of the selected at least one uplink logical channel is updated.

[0097] For example, for the selected at least one uplink logical channel, the priority is updated based on whether there is delay urgent data, including (1) and / or (2):

[0098] (1) If there is delay urgent data in the uplink logical channel, the priority of the uplink logical channel is set to the channel priority of the delay urgent data.

[0099] (2) If there is no delay urgent data in the uplink logical channel, the priority of the uplink logical channel is set to the channel priority of the delay urgent data.

[0100] The channel priority of the delay urgent data can be the highest priority in the priority of the at least one uplink logical channel. The channel priority of the delay urgent data can be the existing priority of the logical channel for sending the XR service data.

[0101] It can be seen that when the priority of the selected at least one uplink logical channel is updated, for the uplink logical channel with delay urgent data, the channel priority of the delay urgent data (for example, the preset highest priority or the priority configured by the network device) is used; for the uplink logical channel without delay urgent data, the channel priority of the delay urgent data is used.

[0102] In step 402, based on the updated priority of the uplink logical channel, the first round of resource allocation is performed.

[0103] Based on (1) and / or (2) described above, the priority of the updated uplink logical channel for the selected at least one uplink logical channel is the channel priority with delay-critical data or the channel priority without delay-critical data, and thus the first round of resource allocation is performed based on the channel priority with delay-critical data or the channel priority without delay-critical data.

[0104] The channel priority with delay-critical data or the channel priority without delay-critical data is used to perform the first round of resource allocation, including the following two ways:

[0105] Way one: for one or more uplink logical channels with a number of tokens in the token bucket greater than zero (Bj>0) in the selected at least one uplink logical channel, the first round of resource allocation is performed for the one or more uplink logical channels in descending order of the priority of the one or more uplink logical channels.

[0106] For example, if there is no delay-critical data in the one or more uplink logical channels, for the one or more uplink logical channels with a number of tokens in the token bucket greater than zero (Bj>0), the first round of resource allocation is performed for the one or more uplink logical channels in descending order of the channel priority without delay-critical data.

[0107] Way two: for the selected at least one uplink logical channel, the first round of resource allocation is performed for the selected at least one uplink logical channel in descending order of the priority of the at least one uplink logical channel.

[0108] For example, if there is delay-critical data in the at least one uplink logical channel, the first round of resource allocation is performed for the selected at least one uplink logical channel in descending order of the priority of the at least one uplink logical channel without considering the principle that the number of tokens in the token bucket is greater than zero (Bj>0).

[0109] It can be seen that, in the embodiments of the present disclosure, after the uplink logical channel is selected in the selection process of the uplink logical channel, the priority of the selected at least one uplink logical channel is updated, and then the first round of resource allocation is performed for the updated uplink logical channel, and the resource is preferentially allocated to the delay-critical data, so that the transmission requirement of the data with delay requirement can be better met, and the user experience is improved.

[0110] In some embodiments, after the first round of resource allocation is performed based on the priority of the uplink logical channel with the updated priority in step 402, the uplink resource allocation method further includes steps 403 and 404 not shown in FIG. 4:

[0111] In step 403, after the first round of resource allocation is performed, if there is remaining resource, the priority of the at least one uplink logical channel is updated again.

[0112] wherein the remaining resources can be used by logical channels that do not contain transmission delay-critical data and / or do not contain data that requires synchronous transmission.

[0113] For example, the priority of the at least one uplink logical channel is updated again, including (1) and / or (2):

[0114] (1) For the uplink logical channel whose priority has been updated to the priority of the channel that contains delay-critical data, the priority is updated again. The uplink logical channel whose priority has been updated to the priority of the channel that contains delay-critical data refers to the logical channel whose priority has been set to the priority of the channel that contains delay-critical data based on whether there is delay-critical data before the first round of resource allocation.

[0115] (2) For the uplink logical channel configured with the priority of the channel that contains delay-critical data, the priority is updated again.

[0116] wherein the priority is updated again in (1) and / or (2) includes (A) or (B):

[0117] (A) If there is delay-critical data in the uplink logical channel, the priority of the uplink logical channel is set to a first priority.

[0118] (B) If there is no delay-critical data in the uplink logical channel, the priority of the uplink logical channel is set to a second priority.

[0119] wherein the first priority is higher than the second priority, or the first priority is the highest priority among the priorities of the at least one uplink logical channel. Optionally, the first priority can be the same as or different from the priority of the channel that contains delay-critical data, and the second priority can be the same as or different from the priority of the channel that does not contain delay-critical data. The first priority and / or the second priority is configured by the network device.

[0120] For example, the network device configures that the priority of the logical channel corresponding to condition 1 is the first priority, and the priority of the logical channel corresponding to condition 2 is the second priority. Wherein condition 1 is that the uplink logical channel contains delay-critical data, that is, the remaining delay of the data in the uplink logical channel is less than the delay threshold indicated by the threshold information, so when the uplink logical channel meets condition 1, the priority of the uplink logical channel is updated to the first priority. Condition 2 is that the uplink logical channel does not contain delay-critical data, so when the uplink logical channel meets condition 2, the priority of the uplink logical channel is updated to the second priority. Wherein the first priority and the priority of the channel that contains delay-critical data used in the first round of allocation can be the same or different. The second priority and the priority of the channel that does not contain delay-critical data used in the first round of allocation can be the same or different.

[0121] In step 404, a second round of resource allocation is performed based on the priority of the re-updated uplink logical channel.

[0122] For example, without considering the principle that the number of tokens in the token bucket is greater than zero (Bj>0), the second round of resource allocation is performed on the re-updated uplink logical channel in descending order of the priority of the re-updated uplink logical channel.

[0123] Embodiment one

[0124] This embodiment discloses an interaction process between a terminal (UE) and a network device (gNB), which involves the selection of an uplink logical channel. The interaction process includes the following steps 1 to step 4:

[0125] Step 1: The UE obtains configuration information sent by the gNB.

[0126] The configuration information includes semi-static resources for sending XR service data. The semi-static resources include semi-static resources for sending XR service delay-critical data and / or dedicated semi-static resources for sending XR service data.

[0127] The configuration information further includes CG resources (i.e., the above-mentioned semi-static resources are CG resources), index information of the CG resources, and first indication information (the first indication information is used to indicate CG resources for preferentially sending XR service delay-critical data, dedicated CG resources for sending XR service data, or CG resources for sending data with synchronization transmission requirements).

[0128] Step 2: The UE selects an uplink logical channel that satisfies the constraint condition based on the constraint condition of the semi-static resources for sending XR service data.

[0129] The constraint condition specifically includes at least one of the following (A) to (E):

[0130] (A) The remaining delay of the uplink logical channel of the terminal in which there is data is less than a preset delay threshold, and the preset delay threshold is a threshold or a protocol agreed threshold.

[0131] (B) There is delay-critical data in the uplink logical channel of the terminal.

[0132] (C) The mapping restriction of the uplink logical channel of the terminal is configured with allowed identification or index information of the semi-static resources.

[0133] (D) The mapping restriction of the uplink logical channel of the terminal is configured with allowed identification of XR service delay-critical data;

[0134] (E) there is data in the uplink logical channel of the terminal that needs to be transmitted synchronously.

[0135] Step 3: The UE performs an uplink resource allocation process on the at least one uplink logical channel selected in step 2.

[0136] The uplink resource allocation process can follow the scheme of the related art, or the uplink resource allocation process in Embodiment Two can be used.

[0137] Step 4: The UE transmits the data of the at least one uplink logical channel selected in step 2 to the network device on the allocated uplink resources. Optionally, the UE transmits the first data (e.g., XR service data) and / or the data of the uplink logical channel that meets the constraint condition on the semi-static resources in the configuration information. Optionally, the UE performs the selection process of the uplink logical channel described above when performing new transmission.

[0138] Embodiment Two

[0139] This embodiment provides an uplink resource allocation process. Specifically, it includes the following steps A to step D:

[0140] Step A: Priority update is performed on the at least one uplink logical channel selected in step 2 of Embodiment One.

[0141] For example, for the selected at least one uplink logical channel, priority update is performed based on whether there is XR service latency urgent data, including (1) and / or (2):

[0142] (1) If there is XR service latency urgent data in the uplink logical channel, the priority of the uplink logical channel is set to the priority of the channel with latency urgent data.

[0143] (2) If there is no XR service latency urgent data in the uplink logical channel, the priority of the uplink logical channel is set to the priority of the channel without latency urgent data.

[0144] Step B: Based on the updated priority of the uplink logical channel, a first round of resource allocation is performed.

[0145] In the first round of resource allocation, if there is XR service latency urgent data in the uplink logical channel, i.e., the uplink logical channel with high priority and considering latency, the uplink resource allocation process is performed in descending order of LCP (Logical Channel Prioritization) priority without considering the principle that the number of tokens in the token bucket is greater than zero (Bj>0).

[0146] Step C: After performing the first round of resource allocation, if there is remaining resources, the priority of the at least one uplink logical channel is updated again.

[0147] For example, the re-updating the priority of the at least one uplink logical channel comprises (1) and / or (2):

[0148] (1) re-updating the priority for the uplink logical channel with the latency-critical data.

[0149] (2) re-updating the priority for the uplink logical channel without the latency-critical data.

[0150] The re-updating the priority mentioned in (1) and (2) is in Mode One or Mode Two:

[0151] Mode One: if there is latency-critical data in the uplink logical channel, the priority of the uplink logical channel is set to a first priority.

[0152] The first priority can be the same as or different from the channel priority with latency-critical data used in the first round of allocation.

[0153] Mode Two: if there is no latency-critical data in the uplink logical channel, the priority of the uplink logical channel is set to a second priority.

[0154] The first priority is higher than the second priority. The second priority can be the same as or different from the channel priority without latency-critical data used in the first round of allocation.

[0155] For example, the network device configures that the logical channel priority corresponding to condition 1 is the first priority, and the logical channel priority corresponding to condition 2 is the second priority. The condition 1 is that the uplink logical channel has latency-critical data, i.e., there is data in the uplink logical channel with a remaining latency less than the latency threshold indicated by the threshold information, so when the uplink logical channel meets the condition 1, the priority of the uplink logical channel is updated to the first priority. The condition 2 is that the uplink logical channel has no latency-critical data, so when the uplink logical channel meets the condition 2, the priority of the uplink logical channel is updated to the second priority.

[0156] It should be noted that if the uplink logical channel does not meet the condition 1, the priority of the uplink logical channel reverts to the priority that does not meet the condition 1, i.e., the second priority. Here, the reverting process is performed once after each resource allocation, including the resource allocation process of the second round of resource allocation without considering Bj>0.

[0157] Step D: performing the second round of resource allocation based on the priority of the uplink logical channel re-updated.

[0158] For example, without considering the principle that the number of tokens in the token bucket is greater than zero (Bj>0), the logical channels are arranged in descending order of the priority of the updated uplink logical channels, and the second round of resource allocation is performed on the updated uplink logical channels. Wherein, without considering the principle that the number of tokens in the token bucket is greater than zero (Bj>0), it can be understood that when Bj<0 or Bj=0, the logical channel can participate in the relevant resource allocation.

[0159] It can be seen that, before performing the second round of resource allocation, that is, before the resource allocation process without considering the principle that the number of tokens in the token bucket is greater than zero (Bj>0), the priority of the uplink logical channel related to the XR service or the first data is updated, so as to ensure the fairness of data transmission. Because in the second round of resource allocation, it is possible that in the first round of resource allocation process, the UE has included the data with a remaining delay less than the delay threshold in the resource allocation based on the condition that Bj>0 or without considering the condition that Bj>0, and the priority of the uplink logical channel corresponding to the data needs to be calculated as the original priority (for example, the second priority).

[0160] Optionally,

[0161] After performing the first round of resource allocation, if there is remaining resource, the second round of resource allocation is performed using the priority of the uplink logical channel used in the first round of resource allocation; or

[0162] After performing the first round of resource allocation, the number of tokens of the uplink logical channel is updated, and if there is remaining resource, the second round of resource allocation is performed based on the priority of the uplink logical channel used in the first round of resource allocation or using the same uplink logical channel priority as that used in the first round of resource allocation; or

[0163] After performing the first round of resource allocation, if there is remaining resource, the second round of resource allocation is performed, and the first round of resource allocation and the second round of resource allocation use the same uplink logical channel priority.

[0164] It should be noted that in the embodiments of the present disclosure, after performing the first round of resource allocation, the UE performs the update of the number of tokens in the token bucket, and if there is remaining resource, the second round of resource allocation is performed.

[0165] It should be noted that in the embodiments of the present disclosure, optionally, the first round of resource allocation process includes arranging the uplink logical channels for which the channel priority of the delay-critical data is configured for Bj>0 or Bj is not constrained and other selected logical channels in descending order of priority, and allocating resources. Specifically, when allocating resources, resources are preferentially allocated to data of high-priority logical channels. In the second round of resource allocation, all uplink logical channels selected according to the logical channel selection process (may not consider the specific value of Bj) are arranged in descending order of priority, and resources are allocated. Here, the priority of all uplink logical channels selected according to the logical channel selection process can be the same as the priority of the related logical channels in the first round of resource allocation, or the second round of resource allocation does not update the priority of the uplink logical channels. In the first round of resource allocation and the second round of resource allocation, the UE uses the same uplink logical channel priority for the selected logical channels. In this way, the complexity of the resource allocation process can be reduced.

[0166] It should be noted that the delay-critical data mentioned in the embodiments can be directly indicated by a higher layer that there is delay-critical data in the data to be transmitted, for example, the PDCP layer directly indicates that there is delay-critical data in the data to be transmitted in the PDCP layer and / or the RLC layer, and for example, the RLC layer directly indicates that there is delay-critical data in the data to be transmitted in the RLC layer. Optionally, the RLC layer determines whether there is delay-critical data through a delay threshold. The delay threshold can be a threshold value at the bearer level, or can be a delay-critical related threshold value configured for the PDCP layer or the RLC layer, or can be a newly configured delay-critical related threshold value for the MAC layer.

[0167] Determining whether there is delay-critical data through a delay threshold specifically includes obtaining a delay threshold configured by a network device, the delay threshold being used to evaluate whether there is delay-critical data, and if the remaining delay of a data packet is lower than the delay threshold, it is determined that there is delay-critical data, or if the remaining delay of at least one data packet in a data packet set is lower than the delay threshold, it is determined that there is delay-critical data.

[0168] It should be noted that the semi-static resources or resources in all embodiments of the present disclosure can also be used to transmit non-delay-critical data. Delay-critical data can be defined as delay-critical data. Non-delay-critical data can be defined as non-delay-critical data.

[0169] It should be noted that the XR service delay-critical data mentioned in all embodiments of the present disclosure can be extended to other delay-critical data.

[0170] It should be noted that, for the foregoing method embodiments, in order to simply describe, they are all expressed as a combination of a series of actions, but those skilled in the art can understand that the embodiments of the present disclosure are not limited to the action sequence described, because according to the embodiments of the present disclosure, certain steps can be performed in other sequences or simultaneously.
