[0074] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0075] First, the nouns involved in the embodiments of this application are introduced:

[0076] Extended Reality (XR): A broad umbrella for multiple heterogeneous use cases and services, studied and outlined in SA1, SA2, and SA4, including but not limited to TR 22.842 and TR 26.928. Illustrative examples of XR use cases include augmented reality (AR), virtual reality (VR), and mixed reality (MR).

[0077] Extended Reality and Media Services (XRM): XR (Extended Reality) and Media Services.

[0078] Video Slice: A spatially distinct region in a video frame that is encoded separately from other regions in the same frame.

[0079] Packet Data Unit set (PDU set): A PDU set consists of one or more PDUs that carry the payload of an information unit generated at the application layer. For example, the information unit is an XRM frame or a video clip. These pieces of information have the same importance requirements at the application layer. The application layer requires all PDUs in the PDU set to use the corresponding information unit. In some cases, when some PDUs are lost, the application layer can still recover some of the information units. It should be noted that the I-frames, P-frames, etc. mentioned later are just one form of PDU set.

[0080] I-frame: As an intra-coded picture, an I-frame is a complete picture that can be independently encoded and decoded like a JPG image file.

[0081] P-frame: As a predicted picture, a P-frame is not a complete frame and only contains image changes compared to the previous frame. If the reference frame is lost, the P-frame will not be decoded and displayed.

[0082] B-frames: As bidirectionally predicted pictures, B-frames contain the changes between the previous and next reference frames. The more reference frames there are, the higher the compression ratio. However, B-frames can only be decoded if both the previous and next reference frames are available.

[0083] A Group of Pictures (GOP): A GOP consists of a collection of consecutive video frames. The first frame of a GOP is an I-frame, and the subsequent frames can be P-frames or B-frames.

[0084] 5G network system architecture: Please refer to Figure 1. The 5G network system includes: User Equipment (3GPP's naming for mobile terminals) (User Equipment, UE), (Radio) Access Network ((R)AN), User Plane Function (UPF), Data Network (DN) and Control Plane Function.

[0085] Among them, the control plane functions include: Access and Mobility Management Function (AMF), Session Management Function (SMF), Policy Control Function (PCF) and Unified Data Manager (UDM), Application Function (AF), Network Slice Selection Function (NSSF), and Authentication Server Function (AUSF).

[0086] Among them, the UE establishes an access layer connection with the AN through the Uu air interface, exchanges access layer messages and performs wireless data transmission. The UE establishes a non-access layer (NAS) connection with the AMF through the N1 interface and exchanges NAS messages. AMF is the mobility management function in the core network, and SMF is the session management function in the core network. In addition to managing the mobility of the UE, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. PCF is the policy management function in the core network, responsible for formulating policies related to UE mobility management, session management, billing, etc. UPF is the user plane function in the core network, which transmits data with the external data network through the N6 interface and with the AN through the N3 interface.

[0087] XR / Ultra Reliability and Low Latency Communication (URLLC):

[0088] In the future, the 3GPP system will provide more extensive and in-depth support for vertical industries. For example, URLLC requires support for the transmission of services such as industrial automation (Factory Automation), transport automation (Transport Industry), and smart power (Electrical Power Distribution) in the 5G system. XR requires support for the transmission of augmented reality (AR) / virtual reality (VR) / cloud gaming (CG) services. These services generally have reliability and latency requirements, because when scheduling resources for the UE, the quality of service (QoS) requirements of data transmission must be met. From the UE's perspective, the UE power consumption issue also needs to be met to avoid unnecessary power consumption. At the same time, considering the access of a large number of UEs supporting this service, the network capacity requirements must also be guaranteed when allocating resources.

[0089] For example, for URLLC / XR, it is necessary to support services with a minimum latency of 0.5ms and 99,999% reliability. The service can be pseudo-periodic, that is, there is jitter in the service arrival time, that is, the service will not arrive at a certain point, but at any time within a range. At the same time, the service period can be a non-integer period, such as 16.67ms. In addition, the arrival time of different service flows of the same service may vary greatly. For example, for AR, the UL pose period is 4ms, but the UL video period is 16.67ms.

[0090] For AR / VR / cloud gaming, the possible business models are as follows:

[0091] VR: UL posture information + DL video stream

[0092] CG: UL control information + DL video stream

[0093] AR: UL (posture information + UL video stream) + DL video stream

[0094] The control information or posture information cycle is approximately 4ms, and the required packet size is approximately 100 bytes. The video stream cycle is approximately 16.67ms, and the required packet size is approximately 0.67Mbps.

[0095] In addition, each service is pseudo-periodic, meaning it arrives periodically. However, there is jitter in the arrival time of each period, meaning it arrives within a time range.

[0096] In particular, for AR, in uplink transmission, there is posture information and video stream information in one cycle, and the arrival time of the two streams is different.

[0097] In particular, for XR services, the data packet size is variable.

[0098] Among them, XR business features:

[0099] (i) non-integer XR flow period;

[0100] (ii) variable XR data rate;

[0101] (iii) quasi-periodic XR periodicity, so enhancement would be beneficial in this area;

[0102] (iv) There are delay requirements and it is a delay-sensitive business.

[0103] Buffer Status Report (BSR):

[0104] The terminal uses the BSR to inform the serving base station of the UE's uplink buffered data volume, so that the base station can schedule the UE according to the data volume information provided by the terminal. In order to save the BSR reporting overhead, the group reporting method is adopted. Each uplink logical channel (Logical Channel, LCH) corresponds to a logical channel group (Logical Channel Group, LCG), and multiple uplink logical channels can correspond to the same LCG. The correspondence between LCH and LCG is configured by the network through radio resource control (Radio Resource Control, RRC). Schematically, the terminal reports the BSR based on the LCG. In the new radio (NR), each terminal can support up to 8 LCGs.

[0105] Schematically, the BSR triggering conditions include the following:

[0106] 1. Uplink data arrives on a higher-priority logical channel of the UE, triggering a regular BSR.

[0107] 2. The padding portion of the uplink resources allocated to the UE after carrying other uplink data can carry a BSR Media Access Control Control Element (BSR MAC CE). In this case, a Padding BSR is issued.

[0108] 3. The retransmission BSR timer (retxBSR-Timer) times out, and there is at least one uplink logical channel with uplink data to be sent. In this case, a regular BSR is triggered.

[0109] 4. When the periodic BSR timer (periodicBSR-Timer) times out, a periodic BSR (Periodic BSR) is triggered.

[0110] If multiple logical channels trigger a regular BSR at the same time, each of these logical channels triggers a separate regular BSR.

[0111] Schematically, BSR is carried by BSR MAC CE. Based on the reporting content and form, BSR can be divided into the following four types:

[0112] 1. Short BSR;

[0113] 2. Short truncated BSR;

[0114] 3. Long BSR;

[0115] 4. Long truncated BSR;

[0116] Among the above 4 forms of BSR:

[0117] - Short BSR and Short Truncated BSR Use Short BSR and Short Truncated BSR MAC CE to carry the short BSR and short truncated BSR. The size of the BSR MAC CE corresponding to the short BSR and short truncated BSR is fixed and is defined as shown in Figure 2.

[0118] -Long BSR and long truncated BSR use long BSR and long truncated BSR MAC CE to carry the BSR MAC CE corresponding to the long BSR and long truncated BSR. The size of the BSR MAC CE is variable and is defined as shown in Figure 3.

[0119] For regular BSR and periodic BSR:

[0120] - If the number of LCGs with uplink data on the UE is greater than 1, the UE reports a long SBR, which reports the data volume of all LCGs with uplink data;

[0121] - Otherwise, the UE reports a short BSR.

[0122] For a padded BSR:

[0123] - If the number of padding bits is sufficient to carry a short BSR but insufficient to carry a long BSR,

[0124] -If the number of LCGs for uplink data is greater than 1,

[0125] - If the number of padded bits is just enough to carry the segment BSR, the UE reports a shortened truncated BSR, reporting the data volume of the LCG corresponding to the logical channel with the highest priority among the logical channels with uplink data.

[0126] -Otherwise, the UE reports a long truncation BSR. The specific LCG data volume reported is determined by the priority of the highest-priority logical channel contained in the LCG with uplink data. If the highest-priority logical channels contained in multiple LCGs with data have the same priority, the reporting priority order is further determined according to the LCG ID.

[0127] - Otherwise, the UE reports a short BSR.

[0128] - Otherwise, if the number of padded bits is sufficient to carry a long BSR, the UE reports a long BSR, reporting the data volume of all LCGs with uplink data.

[0129] NR MAC package:

[0130] Similar to Long Term Evolution (LTE), in NR, the network allocates uplink transmission resources on a per-UE basis rather than a per-bearer basis. The UE determines which radio bearer data can be placed in the allocated uplink transmission resources.

[0131] Based on the uplink transmission resources configured by the network, the UE needs to determine the amount of data to be transmitted for each logical channel in the initial transmission of the Medium Access Control Packet Data Unit (MAC PDU). In some cases, the UE also needs to allocate resources for the MAC CE.

[0132] Schematically, in order to achieve the multiplexing of uplink logical channels, a priority needs to be assigned to each uplink logical channel. For a MAC PDU of a given size, when there are multiple uplink logical channels with data transmission requirements at the same time, the resources of the MAC PDU are allocated in descending order according to the logical channel priorities corresponding to each uplink logical channel. At the same time, in order to take into account the fairness between different logical channels, the probability of the Prioritized Bit Rate (PBR) is introduced. When the UE performs logical channel multiplexing, it is necessary to first ensure the minimum data rate requirements of each logical channel, so as to avoid the situation where the uplink logical channels with high priority always occupy the uplink resources allocated to the UE by the network, resulting in the UE's other low-priority uplink logical channels being "starved".

[0133] Schematically, to implement uplink logical channel multiplexing, the network RRC configures the following parameters for each uplink logical channel:

[0134] -Logical channel priority: The smaller the priority value, the higher the corresponding priority.

[0135] -PBR: Priority Bit Rate, which indicates the minimum rate that needs to be guaranteed for this logical channel.

[0136] - Bucket Size Duration (bucketSizeDuration, BSD): This parameter determines the depth of the token bucket.

[0137] The UE's MAC uses a token bucket mechanism to implement uplink logical channel multiplexing.

[0138] The UE maintains a variable Bj for each uplink logical channel j, which indicates the number of tokens currently available in the token bucket, as follows:

[0139] 1) When the UE establishes logical channel j, it initializes Bj to 0;

[0140] 2) Before each Logical Channel Prioritization (LCP) process, the UE increases Bj by PBR*T, where T is the time interval from the last time Bj was increased to the current time;

[0141] 3) If Bj updated according to step 2 is greater than the maximum capacity of the token bucket (i.e., PBR*BSD), then Bj is set to the maximum capacity of the token bucket.

[0142] Illustratively, when the UE receives an uplink grant (UL grant) indicating a new transmission, the UE performs logical channel priority processing according to the following steps:

[0143] Step 1: For all logical channels with Bj > 0, resources are allocated in descending order of priority. The resources allocated to each logical channel must only meet the PBR requirement. That is, resources are allocated to the logical channel based on the number of tokens in its corresponding PBR token bucket. If the PBR for a logical channel is set to infinity, logical channels with lower priorities are considered only after the resources for that logical channel are met.

[0144] Step 2: Subtract the size of all MAC service data units (SDUs) multiplexed into the MAC PDU of logical channel j in step 1 from Bj.

[0145] Step 3: If there are still uplink resources remaining after executing steps 1 and 2, regardless of the size of Bj, the remaining resources are allocated to the logical channels in descending order of logical channel priority. Only when the data of the high-priority logical channels has been transmitted and the uplink grant has not been exhausted, the low-priority logical channels can be served. In other words, the UE maximizes data transmission on the high-priority logical channels.

[0146] At the same time, UE should also follow the following principles:

[0147] (1) If the entire Radio Link Control Service Data Unit (RLC SDU) can be filled into the remaining resources, the RLC SDU is not segmented;

[0148] (2) If the UE segments the RLC SDU in the logical channel, it should try to fill the largest segment possible based on the size of the remaining resources;

[0149] (3) UE should maximize data transmission;

[0150] (4) If the uplink grant size is greater than or equal to 8 bits (8 bytes) and the UE has a data transmission requirement, the UE cannot send only the padded BSR or only the padding.

[0151] Illustratively, for different signals and / or logical channels, the UE also needs to follow the following priority order (arranged in descending order of priority) when performing logical channel priority processing:

[0152] -C-RNTI MAC CE or data from UL-CCCH;

[0153] -Configured Grant Confirmation MAC CE;

[0154] - For BSR MAC CE other than padded BSR;

[0155] - Single Entry Power Headroom Report MAC CE (Single Entry PHR MAC CE) or Multiple Entry PHR MAC CE;

[0156] - Data from any logical channel except UL-CCCH;

[0157] -MAC CE for recommended bit rate query;

[0158] - BSR MAC CE for the padded BSR.

[0159] Solution 1: Design or report auxiliary information, or configure or adjust resources or parameters based on auxiliary information.

[0160] FIG4 shows an information transmission method provided by an exemplary embodiment of the present application, including the following steps:

[0161] Step 102: The terminal reports auxiliary information to the network device.

[0162] Schematically, the auxiliary information is used to indicate service information of the terminal.

[0163] Among them, in order to realize the processing of XR business, the terminal can report auxiliary information to the network equipment so that the network equipment can obtain the business information of the terminal and adjust the transmission resources or the configuration of transmission resources, thereby achieving the purpose of increasing system capacity, meeting XR business needs, and avoiding resource waste.

[0352] In addition, the characteristics of the data packet itself, such as which PDU set or data burst the PDU belongs to, the importance of the PDU set or PDU, the SN of the associated PDU set or data burst, and whether it is the first packet or the last packet of the PDU set or data burst, are also included. Optionally, the data packet characteristics can be reported via auxiliary information or carried in the data PDU header or control PDU (such as in the packet or header of at least one of the SDAP, PDCP, RLC, and MAC PDUs) at the access layer.

[0353] d) Auxiliary information reporting includes:

[0354] When the pre-configured or dynamically scheduled UL resources include multiple available resources, or multiple PUSCH occasions, the auxiliary information is transmitted in the first X resources. Optionally, X is the first resource.

[0355] Step 2: The network receives the auxiliary information reported by the UE.

[0356] Optionally, the network performs resource allocation or scheduling based on the auxiliary information, or adjusts resource configuration / RRC configuration parameters, etc. The following lists various optional implementations:

[0357] a) When multiple CG / SPS resources are configured, the UE reports auxiliary information.

[0358] In this case, the network uses the auxiliary information to adjust the configuration parameters of at least one CG / SPS and / or activate or deactivate at least one of the multiple CG / SPSs. Optionally, the auxiliary information is sent via specific CG / SPS resources among the multiple CG / SPSs, such as the first CG / SPS, the CG / SPS with a smaller index, or at least one of the first M CG / SPSs. Optionally, the auxiliary information is reported to the network before the multiple CG / SPS resources are available, such as using a dynamically adjusted grant or UCI / PUCCH / SR.

[0359] b) When multiple CG / SPS resources are configured in one CG / SPS period, the UE reports auxiliary information.

[0360] In this case, the network uses the auxiliary information to adjust the configuration / resource usage parameters of at least one CG / SPS resource location and / or activate or deactivate / use / not use at least one of the multiple CG / SPS resource locations. Optionally, the auxiliary information is sent via a specific CG / SPS resource location among the multiple CG / SPS resource locations, such as the first CG / SPS resource location or at least one of the first M CG / SPS resource locations. Optionally, the auxiliary information is reported to the network before the available resources of a CG / SPS cycle, such as using a dynamically adjusted grant or UCI / PUCCH / SR.

[0361] c) When DCI schedules multiple PUSCH or PDSCH resources, the UE reports auxiliary information.

[0362] In this case, the network adjusts the configuration / resource usage parameters of at least one PUSCH / PDSCH using the auxiliary information, and / or activates or deactivates / uses / does not use at least one of the multiple PUSCH / PDSCH resource locations. Optionally, the auxiliary information is sent via a specific PUSCH / PDSCH resource location among the multiple PUSCH / PDSCH resource locations, such as the first PUSCH / PDSCH resource location, or at least one of the first M PUSCH / PDSCH resource locations. Optionally, the DCI carries a first indication for indicating auxiliary information reporting (for example, the first indication is a special DCI indication, a special authorization indication, an auxiliary information reporting trigger indication, etc.).

[0363] d) When DCI schedules a PUSCH or PDSCH resource, or when a DCI schedules a PUSCH or PDSCH resource, or when DCI periodically schedules a PUSCH or PDSCH resource, the UE reports auxiliary information, or reports auxiliary information on the PUSCH / PDSCH.

[0364] In this case, the network uses the auxiliary information to determine whether to schedule more grants / PUSCHs / PDSCHs. Optionally, the DCI carries a first indication for indicating auxiliary information reporting (eg, a special DCI indication, a special grant indication, an auxiliary information reporting trigger indication, etc.).

[0365] e) When DCI schedules multiple PDSCH resources, or one DCI schedules multiple PDSCH resources, or DCI periodically schedules multiple PDSCH resources, the base station indicates whether to skip specific N PDSCHs on the DCI or a PDSCH at a special position.

[0366] Optionally, the specific N PDSCHs are at least one of the PDSCHs indicated by the DCI. Optionally, the specific N PDSCHs are PDSCHs following a PDSCH in a special position. The UE skips the specific N PDSCHs according to a network instruction.

[0367] In principle, the UE can report the accurate data volume and / or the remaining latency of a finer granularity unit (e.g., LCH or PDU Set). Accordingly, new report triggering criteria would be introduced, e.g.:

[0368] 1) A report is triggered when a fresh PDU set is available;

[0369] 2) A report is triggered when the latency of a PDU set buffered in the MAC layer approaches the PDSB.

[0370] Solution 2: The first reporting information (or first report) is designed or reported, or, based on the first reporting information (or first report), the configuration or adjustment of resources or parameters is achieved.

[0371] FIG5 shows an information transmission method provided by an exemplary embodiment of the present application. The method is executed by a terminal and includes the following steps:

[0372] Step 202: trigger or generate first reporting information.

[0373] Illustratively, the first reporting information is used to trigger the network device to perform at least one of resource allocation, resource adjustment, resource scheduling, parameter adjustment, and parameter configuration.

[0391] Optionally, when a data packet or a data packet of a PDU set arrives, is stored, or is available, a first duration or a first timer is started. For example, when a data packet or a data packet of a PDU set (such as the first data packet, such as determining whether it is this PDU set based on the SN number of the PDU set) arrives, is stored, or is available, the first duration or the first timer is started.

[0523] ii. If 60fps data arrives.

[0524] For example, the availability of specific periodic services / data, the arrival of specific periodic time points, or the arrival of specific periodic services / data triggers the periodic first report. Furthermore, the availability of specific periodic services / data, the arrival of specific periodic time points, or the arrival of specific periodic services / data, and the expiration of the timer corresponding to the periodic BSR (periodicBSR-Timer) or the non-operation of the timer triggers the periodic first report. Optionally, the periodic first report is a periodic BSR or an enhanced periodic BSR.

[0525] h) Data with specific identification arrives.

[0526] i. The data is a PDU or a set of PDUs.

[0527] ii. The specific identifier is at least one of an important identifier, a priority identifier, a dependent identifier, and an I frame.

[0528] i) Specific data arrives.

[0529] i. At least the first PDU in the PDU set arrives, or at least the last PDU arrives;

[0530] ii. A specific PDU in the PDU set arrives (specific position, specific number);

[0531] iii. A new PDU set arrives, such as the SN number of the new PDU set and the PDU set with the SN number of the next PDU set;

[0532] Among them, the PDU set can also be understood as the data or data packet corresponding to the PDU set; and the PDU can also be understood as the data or data packet corresponding to the PDU.

[0533] j) There is data that meets the third condition, which is as follows:

[0534] i.PDB is less than the threshold;

[0535] ii. The remaining transmission delay is less than the threshold;

[0536] iii. The time during which the data is available in the cache is greater than or equal to the threshold;

[0537] iv. The amount of data is greater than the threshold, the amount of data for the first object (such as PDU set, data burst, etc.);

[0538] v. The amount of data to be transmitted or remaining is greater than the threshold, the amount of data to be transmitted or remaining is for the first object (such as PDU set, data burst, etc.);

[0539] k) The first report may trigger MAC CE or SR or CG-UCI or PUSCH-UCI.

[0540] l) The first report may be at least one of BSR, enhanced BSR, SR, CG-UCI, and PUSCH-UCI.

[0541] i. For example, the first report triggers an SR, CG-UCI, or PUSCH-UCI, which can carry the first object identifier and / or the content of the first report in the UCI. Optionally, it can include the content of one or more first objects.

[0542] ii. For example, the first report triggers an SR, which can trigger different SRs based on the data size and / or latency information (e.g., waited latency, remaining latency), and / or data priority / importance. Optionally, different SRs correspond to different SR configurations, such as different SchedulingRequestIds, SchedulingRequestResourceIds, and different PUCCH resource locations. Optionally, each SR can include the contents of one or more of the first objects. Optionally, in the event of a resource conflict, the SR is transmitted first or is considered to have a higher priority.

[0543] iii. For example, if the first report is a BSR or an enhanced BSR, a BSR may be added or modified accordingly. Optionally, a triggered BSR may be a regular BSR, an enhanced regular BSR, or a dedicated BSR. Optionally, the content of one or more first objects may be included.

[0544] iv. Optionally, if a BSR (e.g., a regular BSR, a dedicated BSR, a periodic BSR, etc.) is triggered, or if an enhanced BSR (e.g., an enhanced regular BSR, a dedicated BSR, or an enhanced periodic BSR, etc.) is triggered, then when a MAC PDU including a BSR is generated and more than one LCH / LCG has data available, a long BSR is reported; otherwise, a short BSR or an extended short BSR is reported. Optionally, when a short BSR is reported, an 8-bit length may be used in the buffer size field.

[0545] v. Optionally, if the trigger is a first report (corresponding to triggering a first MAC CE, i.e., a new MAC CE), or an enhanced BSR (for example, an enhanced regular BSR, or a dedicated BSR, or an enhanced periodic BSR, etc.), the first MAC CE or the enhanced BSRMAC CE may carry the first object identifier and / or the content of the first report. Optionally, the MAC CE may include the content of one or more first objects. Accordingly, an extended LCID may be used to identify this MAC CE. Optionally, in the buffer size field, an existing 8-bit buffer size level table, or a 5-bit buffer size level table, or a newly added buffer size level table may be used. The newly added buffer size level table is mainly for large amounts of data, such as data amounts greater than 77284, 107669, or 150,000 bits.

[0546] Optionally, in the buffer size field, the following principles may be adopted to determine which buffer size level list to use (further, conditions may be superimposed: satisfying the above-mentioned conditions for triggering the first report, or in the case of triggering the first report):

[0547] Always use the newly added buffer size level list (the newly added list can also be 8 bits, or 16 bits, or a bit between 8 and 16 bits);

[0548] Always use 8-bit buffer size level lists;

[0549] When the data volume is less than M, the 8-bit buffer size level list is used; otherwise, the newly added buffer size level list is used.

[0550] When the data size is less than M, the 5-bit buffer size level list is used, otherwise, the 8-bit buffer size level list is used;

[0551] When the data volume is less than M, the 5-bit buffer size level list is used; otherwise, the newly added buffer size level list is used.

[0552] When the data volume is less than M, a 5-bit buffer size level list is used; when the data volume is greater than M and less than N, an 8-bit buffer size level list is used; and when the data volume is greater than N, a newly added buffer size level list is used.

[0553] Step 2. The UE generates a first MAC CE, or an enhanced BSR MAC CE, or a BSR MAC CE, or a SR, or a PUSCH-UCI / CG-UCI.

[0554] a) For example: if at least one BSR is triggered and not deleted, and the UL-SCH resource used for the new transmission can carry the BSR MAC CE + its subheader, then a BSR MAC CE can be generated.

[0555] b) For example, if at least one enhanced BSR is triggered and not deleted, and the UL-SCH resource used for the new transmission can carry the enhanced BSR MAC CE + its subheader, then an enhanced BSR MAC CE can be generated. Optionally, an enhanced periodic timer and / or retransmission timer can be started or restarted.

[0556] c) For example, if at least one first report is triggered and not deleted, and the UL-SCH resource used for the new transmission can carry the enhanced MAC CE of the first report + its subheader, then an enhanced MAC CE of the first report can be generated. Optionally, an enhanced periodic timer and / or retransmission timer can be started or restarted.

[0557] d) For example, if the first report is triggered, the SR corresponding to the first report is triggered. The SR resources or configuration used for the SR triggering may be related to the data volume and / or the delay information (waited delay, remaining delay, etc.) and / or data priority / importance. Optionally, different SRs correspond to different SR configurations, such as different SchedulingRequestId, SchedulingRequestResourceId, and different PUCCH resource locations. Optionally, each SR may include the contents of one or more of the first objects. Optionally, in the event of a resource conflict, the SR is transmitted first or the SR is considered to have a high priority.

[0558] In principle, the UE can report the accurate data volume and / or the remaining latency of a finer granularity unit (e.g., LCH or PDU Set). Accordingly, new report triggering criteria would be introduced, e.g.:

[0559] 1) A report is triggered when a fresh PDU set is available;

[0560] 2) A report is triggered when the latency of a PDU set buffered in the MAC layer approaches the PDSB.

[0561] Option 3: Timer related content.

[0562] FIG12 shows a timer configuration method provided by an exemplary embodiment of the present application, and FIG13 shows a schematic diagram of using a timer provided by an exemplary embodiment of the present application. The method is executed by a terminal and includes the following steps:

[0563] Step 402: The network device configures a timer for the terminal.

[0564] Illustratively, the timer is a timer corresponding to the first reporting information, and the duration of the first timer includes the first duration. For the description of the first reporting information, reference may be made to the foregoing content and will not be repeated here. Exemplarily, the first reporting information is a BSR.

[0565] The timer is a periodic timer or a retransmission timer. Optionally, the timer is for one of the following objects: a MAC entity; a terminal; an LCH; an LCH pair; an LCG; a PDU set; a PDU; or a data burst.

[0566] Optionally, the first duration is a duration that matches a service cycle or data rate corresponding to the terminal. In some embodiments, the first duration is an integer duration, or the first duration is a non-integer duration. For example, the first duration is 16.67ms, 60fps.

[0567] After receiving the first duration configured by the terminal for the timer, the terminal may configure the timer.

[0568] Optionally, the timer configuration method provided in the embodiment of the present application further includes at least one of the following steps:

[0569] Optional step 1: When the periodic timer times out, periodically trigger the reporting of the first reporting information.

[0570] Optional step 2: When the periodic timer times out and the second condition is met, trigger the reporting of the first reporting information.

[0571] Optionally, the first reporting information is periodic first reporting information.

[0572] Optional step 3: When the retransmission timer times out and the second condition is met, trigger the reporting of the first reporting information.

[0573] Optional step 4: When triggering at least one reporting information for the same LCG and generating a first MAC CE corresponding to the first reporting information based on the first reporting information in the at least one reporting information, cancel the triggering of other reporting information in the at least one reporting information.

[0574] Optionally, when the timer is running and there is an available UL-SCH, the first MAC CE is not multiplexed, or the timer is not restarted.

[0575] Optional step 5: When the timer is for LCH, or LCH pair, or LCG, and the timer expires, trigger the first reporting information corresponding to the LCH, or LCH pair, or LCG, or trigger the first reporting information corresponding to the terminal, or trigger the first reporting information corresponding to the MAC entity, or trigger the first reporting information corresponding to the LCH, or LCH pair, or LCG of the data to be transmitted.

[0576] Optional step 6: When the first reporting information is triggered and the UL-SCH resource for new transmission carried by the first reporting information carries the first MAC CE and its subheader, generate a first MAC CE.

[0577] Optionally, the terminal may also start or restart a timer.

[0578] Optional step 7: When the first reporting information is triggered, the UL-SCH resource for new transmission carried by the first reporting information carries the first MAC CE and its subheader, and the UL-SCH resource is one of at least one transmission resource, generate a first MAC CE.

[0579] Optionally, the first MAC CE is multiplexed into UL-SCH resources.

[0580] Optionally, other transmission resources except UL-SCH resources in at least one transmission resource do not generate MAC CE, and / or other transmission resources do not multiplex MAC CE, and / or the timer is not started or restarted.

[0581] Optionally, the terminal may also start or restart a timer.

[0582] Optionally, at least one transmission resource is a resource scheduled or preconfigured by the network device; or, at least one transmission resource is a resource scheduled or preconfigured by the network device and corresponds to a first period or a first duration; or, at least one transmission resource is a resource scheduled or preconfigured by the network device and is within the first period or the first duration.

[0583] Optional step 8: When the first reporting information is triggered, and / or there are no UL-SCH resources for carrying the first reporting information or UL-SCH resources for new transmission, and / or the network device configures a dedicated scheduling request SR resource for the terminal, trigger the reporting of the SR information corresponding to the first reporting information.

[0584] Optionally, in the event of a transmission resource conflict, SR information is transmitted first, or the transmission priority of SR information is determined to be high.

[0585] Optional step 9: When the second condition is met, the buffer status report BSR of padding is not triggered or is not supported, or the first reporting information of padding is not triggered or is not supported.

[0586] Among them, the relevant description of the second condition can be referred to the above content and will not be repeated here.

[0587] Optional step 10: When a padded BSR is triggered and the second condition is met, the format of the reported BSR is determined according to the padded bits.

[0588] Among them, the relevant description of the second condition can be referred to the above content and will not be repeated here.

[0589] Optionally, when generating a BSR media access control element MAC CE, an 8-bit buffer size level list is used in the buffer size field in the BSR MAC CE, or a new buffer size level list is added.

[0590] Optionally, the filled BSR is the filled first reporting information.

[0591] In optional step 10, the terminal may determine the format of the reported BSR according to the following method:

[0592] 1> If the number of padding bits is equal to or larger than the size of the Extended Short BSR plus its subheader but smaller than the size of the Long BSR plus its subheader:

[0593] 2> If more than one LCG has data available for transmission when the BSR is to be built:

[0594] 3> If the number of padding bits is smaller than the size of the Long Truncated BSR with zero Buffer Size field plus its subheader:

[0595] 4>Report Extended Short Truncated BSR of the LCG with the highest priority logical channel with data available for transmission.

[0596] 3>Other (else):

[0597] 4> report Long Truncated BSR of the LCG(s) with the logical channels having data available for transmission following a decreasing order of the highest priority logical channel(with or without data available for transmission)in each of these LCG(s), and in case of equal priority, in increasing order of LCGID.

[0598] 2> Otherwise (else):

[0599] 3>Report Extended Short BSR (report Extended Short BSR).

[0600] 1> Otherwise, if the number of padding bits is equal to or larger than the size of the Long BSR plus its subheader:

[0601] 2> Report Long BSR for all LCGs which have data available for transmission.

[0602] It should be understood that the steps on the terminal side and the network device side can be independently implemented as an embodiment of the timer configuration method. For specific explanations, please refer to the above content and will not be repeated here.

[0603] To sum up, in the timer configuration method provided in the embodiment of the present application, the first duration configured for the timer by the network device enables the terminal to modify the BSR configuration and / or the multiplexing conditions of the MAC CE to meet the transmission requirements of the XR service.

[0604] Among them, the timer configuration method provided in the embodiment of the present application can be used alone or in combination with the various information transmission methods given in the above content, and this application does not limit it here.

[0605] For example, the timer configuration method provided in the embodiment of the present application can be implemented as follows:

[0606] Step 1. The network configures a timer for the first report (ie, the aforementioned first reporting information) of a specific duration.

[0607] a) The first report may be a BSR.

[0608] b) The timer can be a periodic timer.

[0609] i. The timer is for one of the MAC entity, UE, LCH, LCH pair, and LCG.

[0610] c) The timer may be a retransmission timer.

[0611] i. The timer is for one of the MAC entity, UE, LCH, LCH pair, and LCG.

[0612] d) The specific duration may be a duration that matches the service cycle or data rate, such as a non-integer duration, such as 16.67ms, 60fps.

[0613] Step 2: The UE receives the network configuration and executes related processes, which may include at least one of the following:

[0614] a) The periodic timer times out, triggering the first report of the period.

[0615] b) When the periodic timer times out and at least one of the second conditions is met, triggering a first report. Optionally, the first report is a periodic first report.

[0616] c) triggering a first report when the retransmission timer times out and at least one of the second conditions is met, or when the retransmission timer times out and at least one of the second conditions is met.

[0617] d) If there are multiple first reporting triggers for the same LCG, when one of the first reports generates a first reporting MAC CE, the other first reporting triggers are canceled.

[0618] e) If there are multiple first reporting triggers for the same LCG, when the first reporting generates a first reporting MAC CE, if the timer is running, when there is an available UL-SCH, the first reporting trigger MAC CE of the LCG is not multiplexed, or the timer is not restarted.

[0619] f) If the periodic timer is for LCH, LCH pair, LCG, when the periodic timer of LCH, LCH pair, LCG expires, it triggers the first report of LCH, LCH pair, LCG, or triggers the first report of UE / MAC entity, or triggers the first report of LCH / LCG / LCH pair with data to be transmitted.

[0620] g) If the retransmission timer is for LCH, LCH pair, LCG, when the retransmission timer of LCH, LCH pair, LCG expires, it triggers the first report of LCH, LCH pair, LCG, or triggers the first report of UE / MAC entity, or triggers the first report of LCH / LCG / LCH pair with data to be transmitted.

[0621] h) When the first report is triggered, if the newly transmitted UL-SCH can carry the first reported MAC CE and its subheader, the first reported MAC CE is generated (further, the MAC CE is multiplexed into the UL-SCH). Furthermore, a timer is started or restarted.

[0622] i) In the case of a first report trigger, if the UL-SCH that can carry the newly transmitted MAC CE and its subheader can carry the first reported MAC CE, and the UL-SCH corresponds to one of multiple resources scheduled or pre-configured by the network, then a MAC CE for the first report is generated (furthermore, the MAC CE is multiplexed into the UL-SCH). Furthermore, a timer is started or restarted. Optionally, no MAC CE is generated and / or no MAC CE is multiplexed and / or a timer is started for other resources in the multiple resources.

[0623] j) In the event of a first report trigger, if the UL-SCH that can carry the newly transmitted MAC CE and its subheader can carry the first reported MAC CE and its subheader, and the UL-SCH corresponds to one of multiple resources scheduled or preconfigured by the network within a certain period or duration, then a first reported MAC CE is generated (further, the MAC CE is multiplexed into the UL-SCH). Furthermore, a timer is started or restarted. Optionally, no MAC CE is generated and / or no MAC CE is multiplexed and / or a timer is started for other resources in the multiple resources.

[0624] k) When a first report is triggered, and / or when there is no UL-SCH capable of carrying the MAC CE and its subheader for the first report, and / or when a dedicated SR is configured, trigger the SR corresponding to the first report. (Optionally, in the event of resource conflict, the SR is transmitted first or is considered to have a higher priority.)

[0625] l) When at least one of the second conditions is met, the padding BSR is not triggered or supported, or the padding first report is not triggered or supported.

[0626] m) When a padded BSR is triggered and at least one of the second conditions is met, the MAC entity will determine the format of the reported BR based on the bit position.

[0627] Optionally, the buffer size field in the BSR MAC CE may use the existing 8-bit buffer size level table, or the newly added buffer size level table (newly added buffer size level table) involved in the aforementioned embodiment.

[0628] Optionally, the BSR padding can be extended to pad the first report. The corresponding MAC CE format and / or content of the first report can reuse the existing BSR MAC CE format or modify the existing BSR MAC CE format. For example, the content of some fields can be modified, such as changing the LCG to the LC ID, PDU set identifier; or some new content can be added, such as adding delay information.

[0629] In principle, the UE can report the accurate data volume and / or the remaining latency of a finer granularity unit (e.g., LCH or PDU Set). Accordingly, new report triggering criteria would be introduced, e.g.:

[0630] 1) A report is triggered when a fresh PDU set is available;

[0631] 2) A report is triggered when the latency of a PDU set buffered in the MAC layer approaches the PDSB.

[0632] Solution 4: Uplink / downlink transmission, or efficient uplink / downlink transmission, or interaction under uplink / downlink transmission.

[0633] FIG14 shows an information transmission method provided by an exemplary embodiment of the present application, comprising the following steps:

[0634] Step 502: The network device sends instruction information to the terminal.

[0635] Illustratively, the indication information is used to instruct the terminal to process and / or use transmission resources.

[0636] Several optional implementations of step 502 are given below:

[0637] 1. In the case of downlink transmission, there are several optional implementation methods:

[0720] In NR, based on the uplink transmission resources configured by the network device, the terminal needs to determine the amount of data to transmit for each logical channel in the initial MAC PDU. In some embodiments, the terminal also allocates resources for the MAC CE. To enable uplink logical channel multiplexing, each uplink logical channel needs to be assigned a priority.

[0731] Optionally, in the LCP process, the first PDU or the first PDU set is given priority, or the LCH priority is given priority. This can be specifically implemented as follows:

[0732] During the LCP process, give priority to the first PDU, or give priority to the LCH corresponding to the first PDU, or give priority to placing the data corresponding to the first PDU into the MAC PDU, or adjust the priority of the LCH or LCH group corresponding to the first PDU to a high priority, or give priority to the first PDU set, or give priority to the LCH corresponding to the first PDU set, or give priority to placing the data corresponding to the first PDU set into the MAC PDU, or adjust the priority of the MAC PDU or LCH during the LCP process, or adjust the priority of the LCH or LCH group corresponding to the first PDU set to a high priority;

[0733] Alternatively, during the LCP process, the first PDU is given secondary priority, or the LCH of the first PDU is given secondary priority, or the data corresponding to the first PDU is placed in the MAC PDU as a secondary priority, or the priority of the LCH or LCH group corresponding to the first PDU is adjusted to the second highest priority, or the first PDU set is given secondary priority, or the LCH corresponding to the first PDU set is given secondary priority, or the data corresponding to the first PDU set is placed in the MAC PDU as a secondary priority, or the priority of the LCH or LCH group corresponding to the first PDU set is adjusted to the second highest priority.

[0734] The first PDU set is a specified PDU set and / or an associated PDU set; the first PDU is a specified PDU or a specified data packet. Optionally, the specified PDU set is a data packet with a third identifier, or the specified PDU set is the first data packet; the specified PDU is a data packet with a third identifier, or the specified PDU is the first data packet.

[0736] For example, the first data packet is a specific data packet, where the specific data packet is one of important, prioritized, having high latency requirement, having small PSDB, having latency or residual latency less than a threshold, having latency or residual latency less than a threshold (less than others, other LCHs, other LCHs of the same priority), having PSDB less than or equal to a threshold, having latency greater than threshold 1 and less than threshold 2, or having a data packet that does not meet or is about to not meet PSDB requirements.

[0737] In an embodiment of the present application, at least one of the PSDB, delay, remaining PSDB, and remaining delay is determined by MAC or PDCP statistics, wherein the MAC or PDCP determines at least one of the PSDB, delay, remaining PSDB, and remaining delay based on a first duration or a first timer.

[0738] Optionally, when a data packet or a data packet of a PDU set arrives, is stored, or is available, a first duration or a first timer is started. For example, when a data packet or a data packet of a PDU set (such as the first data packet, such as determining whether it is this PDU set based on the SN number of the PDU set) arrives, is stored, or is available, the first duration or the first timer is started.

[0739] Optionally, during the LCP process, or in the case of MAC PDU packetization, the delay / remaining delay / PSDB / remaining PSDB / duration are determined.

[0740] Optionally, the determination of PSDB, delay, remaining PSDB, remaining delay, and duration may be performed in MAC or PDCP. Exemplarily, PSDB, delay, remaining PSDB, remaining delay, and duration may be exchanged to MAC by other layers (such as PDCP).

[0741] Optionally, whether it is a data packet of a PDU set can be determined by MAC based on a high-layer packet header, or based on inter-layer interaction, or based on a control PDU.

[0742] The descriptions related to delay in the embodiments of this application are all applicable to the above content and will not be repeated here.

[0743] Optionally, during the LCP process, the number of available tokens in the token bucket corresponding to the logical channel needs to be considered, as follows:

[0744] In the LCP process, the size of the PDU set corresponding to the first logical channel is given priority before the first variable is subtracted from the MAC PDU size, or the size of the first associated PDU set corresponding to the first logical channel is given priority before the first variable is subtracted from the MAC PDU size; or

[0745] In the LCP process, the size of the PDU set corresponding to the first logical channel is considered after subtracting the first variable from the MAC PDU size, or the size of the first associated PDU set is considered after subtracting the first variable from the MAC PDU size; or

[0746] In the LCP process, the size of the PDU set corresponding to the second logical channel is given priority before the second variable is subtracted from the MAC PDU size, or the size of the second associated PDU set corresponding to the second logical channel is given priority before the second variable is subtracted from the MAC PDU size; or

[0747] In the LCP process, the size of the PDU set corresponding to the second logical channel is considered after subtracting the second variable from the MAC PDU size, or the size of the second associated PDU set is considered after subtracting the second variable from the MAC PDU size; or

[0748] In the LCP process, the sizes of the PDU sets corresponding to the first logical channel and the second logical channel having an associated relationship are given priority before the first variable and the second variable are subtracted from the MAC PDU size, or the sizes of the third associated PDU sets corresponding to the first logical channel and the second logical channel having an associated relationship are given priority before the first variable and the second variable are subtracted from the MAC PDU size;

[0749] Alternatively, in the LCP process, after subtracting the first variable and the second variable from the MAC PDU size, the size of the associated PDU set corresponding to the first logical channel and the second logical channel having an associated relationship is given priority, or after subtracting the first variable and the second variable from the MAC PDU size, the remaining size of the third associated PDU set is given priority;

[0750] Among them, the first variable is used to indicate the number of tokens available in the token bucket corresponding to the first logical channel, and the second variable is used to indicate the number of tokens available in the token bucket corresponding to the second logical channel. The first logical channel is the logical channel corresponding to the specified PDU set, and the second logical channel is the logical channel corresponding to the associated PDU set.

[0751] Optionally, the association relationship between the first logical channel and the second logical channel is determined based on at least one of RRC configuration, RRC packet header, data packet header, terminal inter-layer interaction, and high-level control PDU.

[0752] Optionally, during the LCP process or during the MAC PDU assembly process, indication information is carried in the MAC PDU, and the indication information is used to request the network device to allocate transmission resources;

[0753] The indication information is carried when one of the following situations is met: there is a specified PDU; there is an associated PDU set; there is an associated PDU set and part or all of the data of the associated PDU set cannot be carried in the MAC PDU; there is a specified PDU set; all or part of the data of the specified PDU set is not carried in the MAC PDU; all or part of the data of the specified PDU is not carried in the MAC PDU.

[0754] Optionally, the indication information is one of a request indication, auxiliary information, and first reporting information. The description of the auxiliary information and the first reporting information can be referred to the above content and will not be repeated here.

[0755] Optionally, the indication information is one of MAC CE, SR, UCI, CG-UCI, and PUSCH-UCI corresponding to the first reporting information.

[0756] Optionally, during the LCP process, if there are remaining resources in the MAC PDU, priority is given to the first PDU, or the data or remaining data of the first PDU is placed in the MAC PDU, or the first PDU set is given priority, or the data or remaining data of the first PDU set is placed in the MAC PDU; wherein the first PDU set is a specified PDU set and / or an associated PDU set.

[0757] Referring to FIG16 , an embodiment of the present application provides two optional processing methods for logical channel priorities:

[0758] Solution 1:

[0759] Optionally, the information transmission method provided in the embodiment of the present application further includes:

[0760] determining a size of remaining data of the PDU or PDU set in the third logical channel in case it is determined that data of the PDU or PDU set in the third logical channel is multiplexed into the size of the MAC PDU;

[0761] Subtract the size of the remaining data of the PDU or PDU set in the third logical channel from the third variable;

[0762] The third variable is used to indicate the number of available tokens in the token bucket corresponding to the third logical channel.

[0763] Based on the above, taking logical channel j as an example, when receiving an uplink grant indicating a new transmission, the terminal performs logical channel priority processing according to the following steps:

[0764] Step 1: For all logical channels with Bj > 0, resources are allocated in descending order of priority. The resources allocated to each logical channel must only meet the PBR requirement. That is, resources are allocated to the logical channel based on the number of tokens in its corresponding PBR token bucket. If the PBR for a logical channel is set to infinity, logical channels with lower priorities are considered only after the resources for that logical channel are met.

[0765] Step 2: Subtract the size of all MAC SDUs of logical channel j multiplexed into the MAC PDU in step 1 from Bj.

[0766] Step 3: Determine the size of the data of the PDU set in logical channel j multiplexed into the MAC PDU, and determine the size of the remaining data of the PDU set in logical channel j. Subtract the size of the remaining data of the PDU set in logical channel j from Bj.

[0767] Step 4: If there are still uplink resources remaining after executing steps 1, 2, and 3, regardless of the size of Bj, the remaining resources are allocated to the logical channels in descending order of logical channel priority. Low-priority logical channels can only be served when all data on high-priority logical channels has been transmitted and uplink grants have not been exhausted. In other words, the terminal maximizes data transmission on high-priority logical channels.

[0768] Solution 2:

[0769] Optionally, the information transmission method provided in the embodiment of the present application further includes:

[0770] Resources are allocated to the at least one logical channel according to a size of a PDU or a PDU set corresponding to the at least one logical channel.

[0771] Optionally, the fourth variable is subtracted from the size of the MAC service data unit MAC SDU multiplexed into the MAC PDU in the fourth logical channel.

[0772] Optionally, resources are allocated to at least one logical channel according to the number of tokens in the token bucket corresponding to the logical channel minus the size of the PDU or PDU set already allocated to the logical channel.

[0773] Based on the above content, still taking logical channel j as an example, when receiving an uplink grant indicating a new transmission, the terminal performs logical channel priority processing according to the following steps:

[0774] Step 1: For all logical channels with Bj > 0, allocate resources in descending order of priority. The resources allocated to each logical channel must only meet the requirements of the PDU set. That is, resources are allocated to the logical channel based on the size of the PDU set corresponding to the logical channel. Bj is calculated by subtracting the size of all MAC SDUs multiplexed into the MAC PDU for logical channel j in this step.

[0775] Step 2: For all logical channels with Bj > 0, resources are allocated in descending order of priority. The resources allocated to each logical channel must only meet the PBR requirement. This means that resources are allocated based on the number of tokens in the corresponding PBR token bucket, or based on the number of tokens in the corresponding PBR token bucket minus the size of the PDU set allocated to the logical channel in the first step. If the PBR for a logical channel is set to infinity, logical channels with lower priority are considered only after the resources for that logical channel are met.

[0776] Step 3: Subtract the size of all MAC SDUs of logical channel j multiplexed into the MAC PDU in step 2 from Bj.

[0777] Step 4: If there are still uplink resources remaining after executing steps 1, 2, and 3, regardless of the size of Bj, the remaining resources are allocated to the logical channels in descending order of logical channel priority. Low-priority logical channels can only be served when all data on high-priority logical channels has been transmitted and uplink grants have not been exhausted. In other words, the terminal maximizes data transmission on high-priority logical channels.

[0778] In summary, the method provided in the embodiment of the present application enhances the LCP process, thereby ensuring the differentiated processing between different PDUs or PDU sets mapped to the same LCH or QoS flow. It should be understood that the method provided in the embodiment of the present application can be implemented in combination with the aforementioned multiple embodiments and will not be repeated here.

[0779] For example, taking a PDU set as an example, the method provided in the embodiment of the present application can be implemented as follows:

[0780] Step 1. The UE receives an uplink authorization to transmit a new transmission;

[0781] Step 2. The UE performs the LCP process and generates a MAC PDU for transmission.

[0782] Optionally, the UE performs an LCP process based on information of different PDU sets and / or a mapping relationship between the PDU sets and the QoS flow / LCH. The LCP process includes at least one of the following:

[0783] a) The UE determines the information of different PDU sets and / or the mapping relationship between the PDU set and the QoS flow / LCH based on the RLC / PDCP / SDAP packet header or the higher-level control PDU, or the UE determines the information of different PDU sets and / or the mapping relationship between the PDU set and the QoS flow / LCH based on the inter-layer interaction within the UE, or the UE determines the mapping relationship between the PDU set and the QoS flow / LCH based on the RRC configuration, and determines the information of different PDU sets based on the higher-level packet header / inter-layer interaction / high-level control PDU.

[0784] b) During the LCP process, the UE prioritizes a specific PDU set, or prioritizes placing data of a specific PDU set into the MAC PDU, or adjusts the LCH priority in this MAC PDU or LCP process, or adjusts the priority of the LCH / LCH group corresponding to the specific PDU set to high or highest priority. A specific PDU set is a data packet with a specific identifier, or an associated PDU set; the specific identifier can be importance, priority, latency value, etc.

[0785] c) During the LCP process, the UE gives priority to a specific PDU set, or places the data of a specific PDU set into the MAC PDU, or the UE gives priority to the size of the specific PDU set corresponding to LCH J before subtracting Bj (for LCH j) from the MAC PDU size. Alternatively, during the LCP process, the UE gives low priority to a specific PDU set, or places the data of a specific PDU set into the MAC PDU, or the UE considers the size of the specific PDU set corresponding to LCH J (or the remaining size of the PDU set) after subtracting Bj (for LCH j) from the MAC PDU size. The specific PDU set is a data packet with a specific identifier, or an associated PDU set; the specific identifier can be importance, priority, delay value, etc.

[0786] d) During the LCP process, the UE gives priority to the associated PDU set, or gives priority to placing the data of the associated PDU set into the MAC PDU, or the UE gives priority to the size of the associated PDU set corresponding to the associated LCH j and k before subtracting Bj (for LCH j) and Bk (for LCH k) from the MAC PDU size.

Optionally, the association relationship between LCH j and k can be determined according to the RRC configuration, or according to the packet header, or according to the UE inter-layer interaction, or according to the high-layer control PDU.

[0787] e) During the LCP process, or during the MAC PDU assembly process, if the UE finds that there is an associated PDU set, or that there is an associated PDU set and the data of the associated PDU set cannot all be carried in the MAC PDU, or that there is an associated PDU set and part of the data of the associated PDU set cannot be carried in the MAC PDU, or that there is a specific PDU set, or that the data of the specific PDU set cannot all be carried in the MAC PDU, the UE carries indication information in the MAC PDU.

[0905] Option 7: Related content of resource selection.

[0906] Optionally, resource selection may be selection of transmission resources or selection of HARQ processes or resources.

[0907] FIG18 shows a resource selection method provided by an exemplary embodiment of the present application. The method is executed by a terminal and includes the following steps:

[0908] Step 802: Select a transmission resource or a Hybrid Automatic Repeat reQuest (HARQ) process according to at least one of the second PDU, the LCH corresponding to the second PDU, the data corresponding to the second PDU, and the logical channel priority.

[0909] Optionally, the resource selection method provided in the embodiment of the present application also includes: giving priority to the logical channel priority; or, giving priority to the second PDU; or, giving priority to the LCH corresponding to the second PDU; or, giving priority to the data corresponding to the second PDU.

[0910] Optionally, the resource selection method provided in the embodiment of the present application further includes at least one of the following:

[0911] Prioritize the logical channel priority before considering the second PDU or the LCH corresponding to the second PDU or the data corresponding to the second PDU; or

[0914] Prioritize the HARQ or resource transmission of the LCH data corresponding to the second PDU set; or

[0915] Prioritize the second PDU; or,

[0916] Prioritize the HARQ or resource transmission of the LCH data corresponding to the second PDU; or

[0917] Adjusting logical channel priorities; or,

[0918] Adjust the priority of the LCH corresponding to the second PDU to a high priority.

[0919] In an embodiment of the present application, the second PDU is a designated PDU or a designated data packet. Optionally, the designated PDU is a data packet having a third identifier, or the designated PDU is the first data packet. The third identifier is one of an importance identifier, a priority identifier, and a delay value.

[0920] Optionally, the first data packet is one of the following data packets: a data packet with an importance higher than a threshold; a data packet with a priority higher than a threshold; a data packet with a delay requirement higher than a threshold; a data packet with a PSDB less than a threshold; a data packet with a delay less than a threshold; a data packet with a remaining delay less than a threshold; a data packet with a delay higher than a first threshold and lower than a second threshold; a data packet that does not meet the PSDB requirements; a data packet that does not meet the PSDB requirements after a first moment; a data packet that does not meet the PSDB requirements within a first time period.

[0921] For example, the first data packet is a specific data packet, where the specific data packet is one of important, prioritized, having high latency requirement, having small PSDB, having latency or residual latency less than a threshold, having latency or residual latency less than a threshold (less than others, other LCHs, other LCHs of the same priority), having PSDB less than or equal to a threshold, having latency greater than threshold 1 and less than threshold 2, or having a data packet that does not meet or is about to not meet PSDB requirements.

[0922] In this embodiment of the present application, at least one of the PSDB, delay, remaining PSDB, and remaining delay is determined by statistics from a media access control (MAC) or a packet data convergence protocol (PDCP). The MAC or PDCP determines at least one of the PSDB, delay, remaining PSDB, and remaining delay based on a first duration or a first timer.

[0923] Optionally, when a data packet or a data packet of a PDU set arrives, is stored, or is available, a first duration or a first timer is started. For example, when a data packet or a data packet of a PDU set (such as the first data packet, such as determining whether it is this PDU set based on the SN number of the PDU set) arrives, is stored, or is available, the first duration or the first timer is started.

[0924] Optionally, during the resource selection process, the delay / remaining delay / PSDB / remaining PSDB / duration are determined.

[0925] Optionally, the determination of PSDB, delay, remaining PSDB, remaining delay, and duration may be performed in MAC or PDCP. Exemplarily, PSDB, delay, remaining PSDB, remaining delay, and duration may be exchanged to MAC by other layers (such as PDCP).

[0926] Optionally, whether it is a data packet of a PDU set can be determined by MAC based on a high-layer packet header, or based on inter-layer interaction, or based on a control PDU.

[0927] The descriptions related to delay in the embodiments of this application are all applicable to the above content and will not be repeated here.

[0928] In summary, the embodiments of the present application provide a new resource selection method.

[0929] Exemplarily, the resource selection method may be implemented as follows:

[0930] In the case of resource conflict, or when selecting resources for priority transmission, or during the HARQ selection process, a specific PDU or LCH / data of a specific PDU is used as one of the selection factors; or, the selection is based on LCH priority and / or a specific PDU or LCH / data of a specific PDU.

[0931] Optionally, during the resource selection process, priority is given to the LCH priority, or priority is given to a specific PDU or LCH / data of a specific PDU. For example, HARQ or grant of a high-priority LCH is transmitted first, or HARQ or grant containing a specific PDU or LCH / data of a specific PDU is transmitted first.

[0932] Optionally, during resource selection, the LCH priority is prioritized before a specific PDU or LCH / data of a specific PDU is considered. For example, in HARQ / grant selection with the same LCH priority, a specific PDU or LCH / data of a specific PDU is prioritized.

[0933] Optionally, during resource selection, a specific PDU or LCH / data of a specific PDU is prioritized over the LCH priority. For example, if both contain a specific PDU or LCH / data of a specific PDU, the one with the higher LCH priority is prioritized during HARQ / grant selection.

[0934] Optionally, during the resource selection process, priority is given to the LCH corresponding to a specific PDU, or priority is given to the HARQ / resource transmission of the LCH data corresponding to a specific PDU set, or priority is given to a specific PDU, or priority is given to the HARQ / resource transmission of the data of a specific PDU, or the LCH priority in this selection is adjusted, or the priority of the LCH / LCH corresponding to the specific PDU is adjusted to high or highest priority.

[0935] Optionally, the specific PDU is a PDU or a PDU set or a data packet.

[0936] For example, the specific PDU is an important, prioritized, low-delay, small-PSDB PDU, etc. Or, the specific PDU is a packet with a specific identifier, and the specific identifier includes any one of importance, priority, delay value, PSDB identifier, etc. Or, the specific PDU is a PDU whose delay or remaining delay or remaining PDB or remaining PSDB is less than a threshold; or, the specific PDU is a PDU whose delay or remaining delay or remaining PDB or remaining PSDB is smaller (smaller than others, other LCHs, other LCHs of the same priority); or the specific PDU is one of the associated PDUs whose PSDB is smaller or smaller than the threshold, whose delay is greater than threshold 1 and smaller than threshold 2, which does not meet or will not meet the PDB / PSDB requirements.

[0937] Illustratively, in the prioritization procedure or HARQ process selection, the UE takes the remaining latency of a PDU Set / LCH / LCG into account; or,

[0938] In the prioritization procedure or HARQ process selection, the UE takes the remaining latency of a PDU Set / LCH / LCG into account to select a prioritized resource; or

[0939] In the prioritization procedure or HARQ process selection, UE take the remaining latency of a PDU Set / LCH / LCG into account based on the indication / enabler / paremanters.

[0940] The indication / enabler / parameters may come from the network side (such as the gNB or core network), or the indication / enabler / parameters may come from the application layer or application server, or the indication / enabler / parameters may be pre-configured to the user (the indication / enabler / paremanters can be from the gNB or pre-configred at the UE).

[0941] In some embodiments, Solution 1, Solution 2, and Solution 3 may be implemented individually or in any combination.

[0942] In some embodiments, at least one of Scheme 1, Scheme 2, and Scheme 3 can be implemented in any combination with at least one of Schemes 4 to 7.

[0943] Optionally, for one or more information related to Solution 1, Solution 2, and Solution 3, if the network device allocates transmission resources, or allocates UL transmission resources based on a report, the UL transmission resource may carry an indication indicating the resource type. Optionally, the resource type indicates which data or LCH can be multiplexed on the UL transmission resource. For the UE, only data or LCH of the corresponding resource type can be multiplexed on the UL transmission resource.

[0944] Optionally, for one or more information involved in Scheme 1, Scheme 2 and Scheme 3, if the network device allocates transmission resources, or allocates UL transmission resources according to the report, an indication may be carried in the UL transmission resource to indicate the resource type or resource indication. Optionally, the resource type or resource indication is used to indicate which data or LCH can be multiplexed on the UL transmission resource, or a first LCP (LCP enhancement in Scheme 5), a first HARQ selection or a prioritization process (HARQ selection or priority selection enhancement in Scheme 7) is used. For the UE, only data or LCH of the corresponding resource type can be multiplexed on the UL transmission resource, or the UE uses a scheme corresponding to the resource indication (such as LCP, HARQ selection, or priority selection) to perform packetization or resource transmission.

[0945] Optionally, if the network device allocates transmission resources, or based on the allocation of UL transmission resources, an indication may be carried in the UL transmission resource, where the indication indicates a resource type. Optionally, the resource type indicates which data or LCH can be multiplexed on the UL transmission resource. For the UE, only data or LCH corresponding to the resource type can be multiplexed on the UL transmission resource.

[0946] Optionally, if the network device allocates transmission resources, or allocates UL transmission resources, an indication may be carried in the UL transmission resource to indicate the resource type or resource indication. Optionally, the resource type or resource indication is used to indicate which data or LCH can be multiplexed on the UL transmission resource, or a first LCP (LCP enhancement in scheme five), a first HARQ selection or a priority process (HARQ selection or priority selection enhancement in scheme seven) is used. For the UE, only data or LCH of the corresponding resource type can be multiplexed on the UL transmission resource, or the UE uses a scheme corresponding to the resource indication (such as LCP, HARQ selection, or priority selection) to perform packetization or resource transmission.

[0947] In other embodiments, packaging, resource selection, or resource transmission may be performed based on specific information.

[0948] Optionally, for LCH, or RLC, or DRB, specific indication information can be configured to indicate the resource type corresponding to the LCH, or RLC, or DRB. Optionally, when the resource type matches (such as the same as) the resource type configured or scheduled by the network, the LCH, or RLC, or DRB can be transmitted using the resources configured or scheduled by the network, or can be carried / multiplexed on the resources configured or scheduled by the network. Optionally, for LCH, or RLC, or DRB, specific information can be configured to indicate the data type corresponding to the LCH, or RLC, or DRB. Optionally, the data type can correspond to the information of the PDU set or data burst, or be the information of the PDU set or data burst (such as attributes, etc.), or the data type can be an identifier supported by the PDU set or data burst. Alternatively, the data type can also be a specific identifier.

[0949] Optionally, the specific indication information, or specific information, may be pre-configured, determined by the UE, or configured by the RRC.
