Terminal device, network device, and terminal device method

Abstract

Exemplary embodiments of the present disclosure relate to an apparatus, method, and computer storage medium for communications. A terminal device receives a configuration including a first threshold associated with a logical channel or a logical channel group, determines whether buffered data for the logical channel includes delayed data based on the configuration, determines a priority value for the logical channel, and performs an LCP procedure based on the priority value for the logical channel. Thus, by increasing the priority of the delayed data, the delayed data is multiplexed in a MAC PDU with a high priority, thereby ensuring transmission of the delayed data. Therefore, it is possible to meet service latency requirements and improve the efficiency of communications between the terminal device and a network device.

Description

[Technical Field]

[0001] FIELD Exemplary embodiments of the present disclosure relate generally to the field of communications technologies, and more particularly to apparatus, methods, and computer-readable media for communications. [Background technology]

[0002] Recently, a new work item on enhancements for extended reality (XR) services is underway in new radio (NR) Release 18 (Rel-18). To better schedule delay-sensitive traffic, delay reporting of buffered data in the uplink may be considered. Network devices may schedule uplink grants for delay-sensitive traffic according to the delay reports. However, current procedures cannot guarantee successful transmission of delayed data. For example, a specific protocol data unit (PDU) or PDU set may exceed the packet delay budget (PDB) or PDU set delay budget (PSDB). Therefore, further research on enhancements is needed.

[0034] As used herein, the term "circuitry" may refer to a hardware circuit and / or a combination of a hardware circuit and software.

As yet another example, a circuit may be any portion of a hardware processor with software, including a digital signal processor, software, and one or more memories, that cooperate to cause a device, such as a terminal device or a network device, to perform various functions.

The term "comprises" and variations thereof should be understood as open-ended terms meaning "including, but not limited to." The term "based on" should be understood as "based at least in part on." The terms "one embodiment" and "embodiment" should be understood as "at least one embodiment." The term "another embodiment" should be understood as "at least one other embodiment." Terms such as "first," "second," etc. may refer to different or the same object. The following may include other explicit and implicit definitions.

[0036] In some instances, values, procedures, or devices are referred to as "best," "lowest," "highest," "minimum," "maximum," etc. It should be understood that such descriptions are intended to illustrate that selections may be made from among many functional alternatives used, and that such selections are not necessarily better, smaller, higher, or otherwise more preferred than other selections.

[0037] It is agreed that delay reporting of buffered data in the uplink should be considered to better schedule delay-sensitive traffic for XR services. For example, several work items in Rel-18 specify buffer status report (BSR) enhancements, including at least a new BS table, and enhancements related to the capacity of buffered data delay reporting in the uplink.

[0038] The UE may perform uplink transmissions to the network. A logical channel prioritization (LCP) procedure is applied for each new transmission. Radio resource control (RRC) determines for each logical channel (LCH) per medium access control (MAC) entity: - priority (increasing priority values ​​indicate lower priority levels), - prioritisedBitRate (sets the Prioritised Bit Rate (PBR)), and - bucketSizeDuration (sets the bucket size duration (BSD:Bucket Size Duration)), The scheduling of uplink data is controlled by signaling

[0039] The following UE variables are used in the logical channel prioritization procedure: - Bj (kept for each logical channel j)

[0040] When a logical channel is established, the MAC entity should initialize the logical channel's Bj to zero. For each logical channel j, the MAC entity should: 1> Before each instance of the LCP procedure, increase Bj by the product PBR × T, where T is the time elapsed since Bj was last increased, 1> If the value of Bj is greater than the bucket size (i.e., PBR × BSD), 2> Set Bj to the bucket size.

[0041] Note that the exact timing at which the UE updates Bj between LCP procedures is determined by the UE implementation, but it is sufficient that Bj is up to date when the grant is processed by the LCP.

[0042] Some XR services may have strict latency requirements. Data with exceeded PDB / PSDB may not be useful, so uplink resources should be allocated before that. If the remaining delay budget is explicitly provided to the network, the network may have the flexibility to schedule uplink grants taking into account the remaining delay budget without exceeding the PDB / PSDB. Although the network can schedule UL grants for delay-sensitive traffic according to the remaining delay budget and / or delay buffer size, current LCP procedures cannot guarantee that delayed data should be multiplexed in the corresponding MAC PDU, which may still cause a particular PDU / PDU set to exceed the PDB / PSDB.

[0043]

[0013] An embodiment of the present disclosure provides a communication solution. In this solution, a terminal device may receive a configuration from a network device, the configuration including a first threshold associated with a logical channel (LCH) or a logical channel group (LCG). The terminal device may determine delayed data and / or non-delayed data for the LCH / LCG based on the configuration, and may further determine a priority value for another LCP procedure. This allows delayed data to be multiplexed in a MAC PDU with a higher priority, thereby solving the problem of delayed data exceeding the delay budget. This makes it possible to guarantee the latency requirements of a service and improve the efficiency of communication between the terminal device and the network device.

[0014] The principles and embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0044] 1 illustrates an exemplary communication system 100 in which some embodiments of the present disclosure may be implemented. The communication network 100 includes a network device 110 and a terminal device 120. The network device 110 may provide a service to the terminal device 120.

[0045] In system 100, assume that terminal device 120 is located within the coverage of network device 110. In some examples, the link from network device 110 to terminal device 120 is referred to as the downlink (DL), and the link from terminal device 120 to network device 110 is referred to as the uplink (UL). In the downlink, network device 110 is the transmit (TX) device (or transmitter) and terminal device 120 is the receive (RX) device (or receiver). In the uplink, terminal device 120 is the transmit TX device (or transmitter) and network device 110 is the RX device (or receiver). In some embodiments, network device 110 and terminal device 120 may communicate using a direct link / channel. The DL may include one or more logical channels, including, but not limited to, a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH). The UL may include one or more logical channels, including but not limited to a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH), where the term "channel" may refer to a carrier or a portion of a carrier consisting of a contiguous set of resource blocks (RBs) over which a channel access procedure is performed in a shared spectrum.

[0046] Communications within communication system 100, for example between network device 110 and terminal device 120, may be achieved according to any suitable communication protocol, including, but not limited to, cellular communication protocols such as first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), sixth generation (6G), wireless local area network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol now known or developed in the future. Further, the communications may utilize any suitable wireless communication technology, including, but not limited to, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplexer (FDD), Time Division Duplexer (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiple Access (OFDMA), and / or any other technology now known or developed in the future.

[0047] Embodiments of the present disclosure may be applied to any suitable scenario. For example, embodiments of the present disclosure may be implemented on a reduced-capability NR device. Alternatively, embodiments of the present disclosure may be implemented within one of NR multiple-input and multiple-output (MIMO), NR sidelink enhancements, NR systems at frequencies higher than 52.6 GHz, extended NR operation up to 71 GHz, narrowband Internet of Things (NB-IoT) / enhanced Machine Type Communication (eMTC) over non-terrestrial networks (NTN), NTN, UE power saving enhancements, NR coverage enhancements, NB-IoT and LTE-MTC, integrated access and backhaul (IAB), NR multicast and broadcast services, or multi-radio dual connectivity enhancements.

[0048] It should be understood that the number of devices (i.e., network devices 110 and terminal devices 120) and their connection relationships and types as shown in Figure 1 are for illustrative purposes only and do not imply any limitations. System 100 may include any appropriate number of devices suitable for implementing embodiments of the present disclosure.

[0049] Reference is now made to Figure 2, which is a signaling diagram illustrating a communication process 200 in accordance with some exemplary embodiments of the present disclosure. For illustrative purposes only, process 200 will be described with reference to Figure 1. Process 200 may involve network device 110 and terminal device 120.

[0050] The network device 110 transmits the setting 212 to the terminal device 120 (210). In some exemplary embodiments, the setting 212 may include at least a first threshold associated with a logical channel (LCH) or a logical channel group (LCG). For example, the LCH may be associated with delay-sensitive traffic. For ease of explanation, the first threshold may be represented as T1. In some examples, the first threshold may be related to delay or the remaining delay budget.

[0051] For ease of explanation, assume that the first LCH (represented as LCH1) is associated with an XR service having strict latency requirements. Assume that the first threshold is associated with the first LCH or the first LCG, the first LCG includes a plurality of LCHs, and the plurality of LCHs includes LCH1. Note that this example is not intended to limit the present disclosure and is merely for illustration, and although applicable to some other cases, it is not described here.

[0052] In some exemplary embodiments, the setting 212 may further include a second threshold associated with an LCH or an LCG. In some examples, the first threshold and the second threshold may be related to delay. In some exemplary embodiments, the first threshold and the second threshold may be used to determine the delay level (abbreviated as "level") of the buffered data in the terminal device 120. For ease of explanation, the second threshold may be represented as T2, and assume that T2 < T1.

[0053] In some other embodiments, configuration 212 may further include a third threshold associated with the LCH or LCG. In some examples, the first and third thresholds may be related to the remaining delay budget. In some exemplary embodiments, the first and third thresholds may be used to determine a delay level for buffered data at terminal device 120. For ease of explanation, the third threshold may be represented as T3, and it is assumed that T3 > T1.

[0054] It should be noted that the settings 212 may include more than two thresholds to determine more levels of delay, but for ease of explanation only, this disclosure describes two thresholds.

[0055] In some exemplary embodiments, the configuration 212 may be included in an RRC message or RRC signaling from the network device 110 .

[0056] In some other embodiments, network device 110 may transmit a first set of settings and a second set of settings associated with logical channels to terminal device 120. In some examples, the first set of settings may be associated with delayed data and the second set of settings may be associated with non-delayed data. In some examples, each of the setting sets may include one or more of a priority, a preferred bit rate, a bucket size duration, or a logical channel group.

[0057] In some exemplary embodiments, network device 110 may further transmit information used to determine the priority value of the LCH, which may be included in configuration 212 or may be included in a separate message different from configuration 212, and the information used to determine the priority value is described below.

[0058] In some demonstrative embodiments, terminal device 120 receives 214 settings 212. Accordingly, terminal device 120 may obtain a first threshold. In some examples, terminal device 120 may obtain a second threshold or a third threshold. Terminal device 120 may further determine whether the buffered data at terminal device 120 includes delayed data based on settings 212.

[0059] In some exemplary embodiments, one threshold is set; in other words, setting 212 includes a first threshold. Terminal device 120 may determine delayed data and / or non-delayed data based on the first threshold. In some examples, the first threshold is related to delay. Terminal device 120 may determine a delay of buffered data of the LCH. If the delay of the buffered data exceeds (or is equal to or greater than) the first threshold, terminal device 120 may determine that the buffered data is delayed data. If the delay of the buffered data is equal to or less than (or less than) the first threshold, terminal device 120 may determine that the buffered data is non-delayed data. In some other examples, the first threshold is related to a remaining delay budget. Terminal device 120 may determine a remaining delay budget of buffered data of the LCH. If the remaining delay budget of the buffered data is equal to or less than (or less than) the first threshold, terminal device 120 may determine that the buffered data is delayed data. If the remaining delay budget of the buffered data exceeds (or is equal to) the first threshold, terminal 120 may determine that the buffered data is non-delayed data.

[0060] In some other exemplary embodiments, two or more thresholds may be set. For example, setting 212 may include a first threshold and a second threshold, or setting 212 may include a first threshold and a third threshold. In some examples, the first threshold and the second threshold may be delay thresholds, i.e., they are related to delay. The terminal device may determine the delay of the buffered data of the LCH. If the delay of the buffered data exceeds (or is greater than or equal to) the first threshold, the terminal device 120 may determine that the buffered data is delayed data having a first level. For example, if the delay > T1, or the delay ≥ T1, the buffered data may be regarded as delayed data having a first level (which may be represented as level 1), such as emergency delay data. If the delay of the buffered data is less than or equal to (or less than) the first threshold and exceeds (or is greater than or equal to) the second threshold, the terminal device 120 may determine that the buffered data is delayed data having a second level. For example, if T2 < delay ≤ T1, or T2 ≤ delay < T1, the buffered data may be regarded as delayed data having a second level (which may be represented as level 2), such as non-emergency delay data. If the delay of the buffered data is less than or equal to (or less than) the second threshold, the terminal device 120 may determine that the buffered data is non-delayed data having a level 3. For example, if the delay ≤ T2, or the delay < T2, the buffered data may be regarded as non-delayed data having a third level (which may be represented as level 3), such as non-delayed data.

[0061] In some other examples, the first threshold and the third threshold may be the remaining delay budget thresholds, that is, they are related to the remaining delay budget. The terminal device may determine the remaining delay budget of the buffered data of the LCH. If the remaining delay budget of the buffered data is below (or less than) the first threshold, the terminal device 120 may determine that the buffered data is delay data having a first level. For example, if the remaining delay budget ≤ T1, or the remaining delay budget < T1, the buffered data may be regarded as delay data having a first level (which may be represented as level 1), such as emergency delay data. If the remaining delay budget of the buffered data is below (or less than) the third threshold and exceeds (or is more than) the first threshold, the terminal device 120 may determine that the buffered data is delay data having a second level. For example, if T1 < the remaining delay budget ≤ T3, or T1 ≤ the remaining delay budget < T3, the buffered data may be regarded as delay data having a second level (which may be represented as level 2), such as non-emergency delay data. If the remaining delay budget of the buffered data exceeds (or is more than) the third threshold, the terminal device 120 may determine that the buffered data is non-delay data having a level three. For example, if the remaining delay budget > T3, or the remaining delay budget ≥ T3, the buffered data may be regarded as non-delay data having a third level (which may be represented as level 3), such as non-delay data.

[0062] It should be understood that the first level is higher than the second level, and the second level is higher than the third level. In some examples, higher-level data is more urgent than lower-level data.

[0063] In some exemplary embodiments, a packet data convergence protocol (PDCP) entity of terminal device 120 may determine whether the buffered data includes delayed data. In some examples, terminal device 120 may determine a delay or remaining delay budget for the buffered data. For example, when a PDU set arrives from an upper layer, a delay timer in the PDCP layer may be started. The length of the delay timer may then be considered the delay of the buffered data, and the difference between the maximum delay budget and the length of the delay timer may be considered the remaining delay budget for the buffered data. In some examples, a PDU set may include multiple SDUs or PDUs, and the delay timer may be started at the arrival time of the first SDU / PDU belonging to the PDU set. Note that all SDUs or PDUs belonging to the same PDU set should share the delay timer and thus have the same delay and remaining delay budget.

[0064] In some other exemplary embodiments, the first threshold included in the configuration 212 may relate to the length of time of a timer associated with the delay. For example, the first threshold may be configured for the PDCP entity of the terminal device 120.

[0065] For example, when the terminal device 120 receives a packet from an upper layer, it may start a timer associated with the packet, and the length of time of the timer may be set as a first threshold (T1). If the timer expires, the terminal device 120 may determine that the packet is delayed data. For example, if the timer expires and the packet is still buffered, the buffered data including this packet is delayed data. If the timer has not expired, the terminal device 120 may determine that the packet is non-delayed data. For example, if the timer is running and the packet is buffered, the buffered data including this packet is non-delayed data. It should be understood that all SDUs or PDUs belonging to the same PDU set should share the timer.

[0066] In some examples, the buffered data in the LCH may not include delayed data. In other words, the buffered data is non-delayed data, and terminal device 120 may perform the LCP procedure in a conventional manner. For example, the priority value of the LCH may be determined based on the information element (IE) "priority." In a specific example, as shown in FIG. 2, terminal device 120 determines (220) that the buffered data includes delayed data.

[0067] Terminal device 120 determines priority values ​​for the logical channels 230. For example, terminal device 120 may increase the priority ranking of LCHs that have delay data.

[0068] In some example embodiments, a delayed data priority may be set, for example, the IE "delayedDataPriority" or the IE "offset" may be set to indicate the priority of the LCH that has delayed data, or to indicate the relative priority (with respect to the IE "priority") of the LCH that has delayed data. For ease of explanation, it is assumed that the IE "delayedDataPriority" or the IE "offset" contains the delayed data priority.

[0069] In some examples, terminal device 120 may determine a priority value of a logical channel based on a delayed data priority. For example, if a logical channel (e.g., LCH1) includes delayed data, the priority value of the logical channel (e.g., LCH1) may be the delayed data priority indicated by the IE "delayedDataPriority" or the IE "offset." For example, if a logical channel does not include delayed data, the priority value of the logical channel may be the priority indicated by the IE "priority."

[0070] In some other examples, if delayed data priority is not set, i.e., if there is no IE "delayedDataPriority" or "offset", the terminal device 120 may, for example, determine the priority value of the logical channel as the priority indicated by the IE "priority", regardless of whether there is delayed data or not.

[0071] In some examples, the priority value of a logical channel may include a first priority value for delayed data and a second priority value for non-delayed data. For example, if the buffered data of a logical channel includes delayed data and non-delayed data, terminal device 120 may determine a first priority value for the delayed data and a second priority value for the non-delayed data, where the first priority value indicates a higher priority than the second priority value. For example, the first priority value may be a delayed data priority indicated by the IE "delayedDataPriority" or the IE "offset." For example, the second priority value may be a priority indicated by the IE "priority."

[0072] In some examples, if the buffered data of a logical channel includes delayed and non-delayed data, the LCH may be viewed as two sub-logical channels, one with delayed data and the other with non-delayed data, where one sub-logical channel with delayed data may have a first priority value and the other sub-logical channel with non-delayed data may have a second priority value.

[0073] In some exemplary embodiments, terminal device 120 may determine different priority values ​​for data having different latency levels (or "levels" for short). For example, configuration 212 may include two or more thresholds (e.g., N thresholds, where N is an integer greater than 1) and multiple priority values ​​(e.g., N+1 priority values). Thus, different latency levels may be assigned different priority values. In some examples, configuration 212 may include two thresholds, such as the first and second thresholds or the first and third thresholds described above, and may further include three priority values, such as values ​​1, 2, and 3. For example, value 1 may indicate a high priority, value 2 may indicate a medium priority, and value 3 may indicate a low priority. For example, value 3 may be the priority indicated by the IE "priority."

[0074] In some examples, delayed data having a first level (e.g., emergency delayed data) may use a value of 1, i.e., a high priority level. In some examples, delayed data having a second level (e.g., non-emergency delayed data) may use a value of 2, i.e., a medium priority level. In some examples, non-delayed data having a third level (e.g., non-delayed data) may use a value of 3, i.e., a low priority level.

[0075] In some examples, a logical channel may be considered as multiple sub-logical channels, eg, N+1 sub-logical channels, with corresponding priority values.

[0076] In some exemplary embodiments, the network device 110 may transmit an indication indicating whether the delayed data should be multiplexed with a higher priority than the non-delayed data. In some examples, this indication may be carried in a new field of the downlink control information (DCI), a random access response (RAR) carrying an uplink grant, or an RRC message. In some examples, this indication may be carried in a separate IE in the RRC message, where the RRC message may be RRC signaling with a configured grant type 1 or type 2.

[0077] Thus, terminal device 120 may receive the indication. In some examples, if the indication indicates that delayed data should be multiplexed at a higher priority than non-delayed data, terminal device 120 may multiplex the delayed data at a higher priority than non-delayed data. For example, the higher priority may be the delayed data priority indicated by the IE "delayedDataPriority" or the IE "offset." In some other examples, if the indication indicates that delayed data should not be multiplexed at a higher priority than non-delayed data, or if this indication is not present, terminal device 120 may multiplex the data in a conventional manner. For example, the priority indicated by the IE "priority" may be used. For example, the absence of an indication may mean that a field or IE carrying the indication is not present.

[0078] In some exemplary embodiments, terminal device 120 may increase the priority order of a logical channel having delay data by one step. In some examples, terminal device 120 may determine a priority value of the logical channel based on the priority indicated by the IE "priority" and may further determine a priority order (e.g., an initial order) for the logical channel. In some examples, if the logical channel is an LCH having delay data, the priority order may be increased by one step. In some examples, the value of the step may be predefined or may be set by network device 110. In some examples, if the delay data of the logical channel has already been multiplexed, in other words, if the logical channel is no longer an LCH having delay data, the priority order may be reset (decreased) to the initial order.

[0079] In some examples, multiple steps may be used for each delay data. For example, different steps may be associated with delay data having different levels. In some examples, terminal device 120 may determine different steps for delay data having different levels. In some examples, terminal device 120 may increase different priorities of delay data having different levels by different steps. That is, the priorities for delay data having different levels may be increased by different steps. For example, the step used for delay data having a first level may be larger than the step used for delay data having a second level. For example, the step used for delay data having a larger delay or a smaller remaining delay budget may be larger than the step used for delay data having a smaller delay or a larger remaining delay budget.

[0080] In some exemplary embodiments, there may be two configuration sets associated with a logical channel received by network device 110, e.g., a first configuration set (Set 1) and a second configuration set (Set 2), where the first configuration set may be associated with delayed data and the second configuration set may be associated with non-delayed data. In some examples, each of the configuration sets may include one or more of parameters such as priority, prioritized bit rate, bucket size duration, or logical channel group.

[0081] In some examples, terminal device 120 may use parameters in a first configuration set for delayed data or logical channels with delayed data. In some examples, terminal device 120 may use parameters in a second configuration set for non-delayed data or logical channels without delayed data. It should be understood that at least one of the parameters (priority, prioritized bit rate, or bucket size duration) may be different for delayed and non-delayed data.

[0082] It should be noted that although this disclosure describes only two configuration sets, more configuration sets may be used for different delay levels, and for the sake of brevity, this disclosure will not provide a detailed description of embodiments with more configuration sets.

[0083] 2, terminal device 120 performs an LCP procedure 240. In some examples, a MAC entity of terminal device 120 may determine a delay buffer size for delayed data of the LCH, and the MAC entity may allocate resources for the delayed data.

[0084] In some examples, there may be multiple logical channels with buffered data, and the terminal device 120 may determine a priority ranking for the multiple logical channels according to the priority value of each logical channel, and may further allocate resources to the multiple logical channels in descending order of priority.

[0085] In some exemplary embodiments, when performing an LCP procedure, delayed data should be served before non-delayed data. In some examples, there may be more than two logical channels with delayed data, and the MAC entity may allocate resources to the delayed data in descending order of priority. In some examples, if any resources remain, all logical channels with Bj greater than 0 are served in descending order of priority, where Bj is maintained for each logical channel j in terminal device 120 and used for the LCP procedure, as described above.

[0086] In some exemplary embodiments, terminal device 120 may follow one or more rules during the LCP procedure, such as maximizing the transmission of delayed data for a logical channel or maximizing the transmission of a PDU set including delayed data. For example, terminal device 120 may maximize the transmission of delayed data for a logical channel, such as a logical channel configured with a first threshold. For example, terminal device 120 may still allocate resources to delayed data even when Bj<0. For example, terminal device 120 may maximize the transmission of a PDU set. That is, a PDU set should be transmitted as a whole if possible.

[0087] In some exemplary embodiments, the LCP procedure according to the present disclosure may be an update to the current LCP procedure. For example, the specification may be updated as follows: TIFF2026506566000002.tif102158

[0088] Additionally or alternatively, terminal device 120 may transmit (250) uplink transmission 252 to network device 110. In some examples, terminal device 120 may transmit the buffered data using the allocated resources. In some examples, if delayed data is multiplexed in a MAC PDU (e.g., at a higher priority), an indication may be carried in the MAC PDU to notify network device 110. For example, the indication to network device 110 may be carried in a MAC control element (CE). On the other side of the communication, network device 110 receives (254) uplink transmission 252, e.g., delayed data multiplexed in a MAC PDU.

[0089] 3A is a schematic diagram 310 of a scenario with two logical channels, LCH 312 and LCH 314, where LCH 312 has delayed data and LCH 314 has non-delayed data, according to some embodiments of the present disclosure.

[0090] The priority of an LCH 312 that has delayed data may be higher than the priority of an LCH 314 that does not have delayed data. For example, the priority value of the LCH 312 is determined based on the IE “delayedDataPriority” associated with the LCH 312, and the priority value of the LCH 314 is determined based on the IE “priority” associated with the LCH 314.

[0091] Terminal device 120 may multiplex delayed data in LCH 312 and then multiplex non-delayed data in LCH 314 .

[0092] 3B is a schematic diagram 320 of a scenario with two logical channels, according to some embodiments of the present disclosure. As shown in FIG. 3B, there are LCH 322 and LCH 324, where LCH 322 has delayed and non-delayed data and LCH 324 has non-delayed data.

[0093] The LCH 322 may be considered as two sub-logical channels: a sub-logical channel (SLCH) with delayed data, i.e., SLCH 321, and a sub-logical channel with non-delayed data, i.e., SLCH 323. The sub-logical channel with delayed data 321 has a higher priority than the priority of the LCH 324, and the sub-logical channel with non-delayed data 323 has a lower priority than the priority of the LCH 324. For example, the priority value of the sub-logical channel with delayed data 321 of the LCH 322 is determined based on the IE “delayedDataPriority” associated with the LCH 322, the priority value of the sub-logical channel with non-delayed data 323 of the LCH 322 is determined based on the IE “priority” associated with the LCH 322, and the priority value of the LCH 324 is determined based on the IE “priority” associated with the LCH 324.

[0094] The terminal device 120 may determine the priority order in the following order: sub-logical channel 321, LCH 324, and sub-logical channel 323. The terminal device 120 may first multiplex the delayed data in LCH 322, then multiplex the non-delayed data in LCH 324, and then multiplex the non-delayed data in LCH 322.

[0095] According to the exemplary embodiment described with reference to Figures 2 to 3B, a setting including at least one threshold may be used by the terminal device to distinguish between delayed data and non-delayed data. By increasing the priority of the delayed data, the delayed data can be multiplexed in the MAC PDU with high priority, thereby ensuring the transmission of the delayed data. Therefore, it is possible to meet the latency requirements of the service and improve the efficiency of communication between the terminal device and the network device.

[0096] 4 is a flowchart of an example method 400 implemented in a terminal device, according to some embodiments of the present disclosure. For illustrative purposes, the method 400 will be described from the perspective of the terminal device 120 and with reference to FIG.

In block 440, the terminal device 120 performs a logical channel prioritization (LCP) procedure based on the priority value for the logical channel.

[0098] In some exemplary embodiments, if the delay of the buffered data is greater than or equal to a first threshold, terminal 120 determines that the buffered data is delayed data. In some exemplary embodiments, if the delay of the buffered data is less than or equal to the first threshold, terminal 120 determines that the buffered data is non-delayed data.

[0107] In some exemplary embodiments, terminal 120 determines different priority values ​​for data having different levels.

[0108] In some exemplary embodiments, terminal device 120 receives an indication from network device 110 indicating whether delayed data should be multiplexed with a higher priority than non-delayed data. In some exemplary embodiments, if the indication indicates that delayed data should be multiplexed with a higher priority than non-delayed data, terminal device 120 multiplexes the delayed data with a higher priority than non-delayed data.

[0109] In some exemplary embodiments, the indication is carried within at least one of a DCI, an RAR carrying an uplink grant, or an RRC message.

[0110] In some exemplary embodiments, if the buffered data for a logical channel includes delayed data, terminal 120 increases the priority of the logical channel by one step.

[0111] In some exemplary embodiments, terminal 120 reduces the priority order after the delayed data has already been multiplexed.

[0112] In some exemplary embodiments, if the buffered data includes delayed data with different levels, terminal 120 determines different steps for the delayed data with different levels, and in some exemplary embodiments, terminal 120 increases the priority of the delayed data with different levels by different steps.

[0113] In some exemplary embodiments, the buffered data includes delayed and non-delayed data, with the delayed data being served before the non-delayed data.

[0114] In some exemplary embodiments, terminal device 120 receives a first set of settings and a second set of settings from network device 110, each of which includes at least one of a priority, a preferred bit rate, a bucket size duration, or a logical channel group, with the first set of settings associated with delayed data and the second set of settings associated with non-delayed data.

[0115] In some exemplary embodiments, terminal 120 maximizes transmission of delayed data for logical channels. In some exemplary embodiments, terminal 120 maximizes transmission of PDU sets that include delayed data.
