[0004] In related technologies, a terminal performs a logical channel prioritization (LCP) procedure in each case of receiving an uplink grant. Specifically, a network side configures a priority for each logical channel (LCH), and the terminal selects an LCH that can meet a condition through LCP mapping restriction in the case of receiving an uplink grant, and performs resource allocation on the selected LCH in a descending order of LCH priority. If the priorities of two LCHs are the same, the terminal implementation determines to allocate resources to the two LCHs equally.

[0054] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0055] I. Multi-Modality (MM) service

[0056] The eXtended reality (XR) service often contains multiple modalities of sub-services, such as video, haptics, and audio, etc., so the service is likely to be mapped to different Quality of Service flow (QoS flow), but there is some correlation between these QoS flows, such as the relative delay between these QoS flows needs to be less than a certain threshold to ensure synchronization.

[0057] The current core network can associate multiple QoS flows as one MM service through a Multi-Modality Service Identifier (MMSID), but the relative delay and priority have more important role in RAN side scheduling / resource allocation.

[0058] For MM service, some processing related to MM service information acquisition and RAN side scheduling is involved, which can include Logical Channel Prioritization (LCP) processing, Delay Status Report (DSR) reporting, discard processing according to priority and overdue information, etc. The processing related to LCP can include:

[0059] 1. The relative delay parameter between different QoS flows of one MM service can be between the data packets of two flows, or between two flows.

[0060] 2. When the relative priority corresponding to one QoS flow is lower than a certain threshold, the logical channel priority corresponding to the QoS flow is improved, so that the user equipment (User Equipment, UE) can be preferentially sent the data whose delay is fast to expire through logical channel priority adjustment;

[0061] 3. Configure an additional LCP priority, when there is a need to associate a multi-modal service to arrive, use the additional priority configured.

[0062] II. Media Access Control (MAC) LCP mechanism

[0063] The network configures a priority for each logical channel (LCH), when the user equipment (UE) receives an uplink grant, first selects the LCH that can meet the conditions through LCP mapping restriction, and then calculates the data size of the MAC protocol data unit (PDU) after filling the data of the logical channel selected by the LCP mapping restriction in the logical channel priority from high to low order according to the data amount Bj of the token bucket corresponding to the logical channel, that is, allocating resources, if the uplink grant is more, then fill the remaining part of each logical channel priority in the order of logical channel priority from high to low. If the priorities of two logical channels are the same, it depends on the implementation of the UE to process equally.

[0064] Among them, the above-mentioned LCP mapping restriction can include allowed subcarrier spacing (SCS) (i.e. allowed SCS), maximum physical uplink shared channel (PUSCH) duration (i.e. maxPUSCH-duration), allowed configured grant (CG) type 1 (i.e. CG type1allowed), allowed serving cell, allowed CG list, allowed physical layer priority (allowed PHY-Priority), allowed hybrid automatic repeat request (HARQ) mode (i.e. allowed HARQ mode) and the like.

[0065] The above-mentioned Bj is the data amount of the token bucket corresponding to the logical channel, and before each execution of the LCP process, Bj is incremented by the product of the prioritized bit rate (PBR) × T, where T is the time elapsed since the last increment of Bj; the maximum value of the above-mentioned Bj is PBR × bucket size duration (BSD).

[0066] The LCP processing method provided by the embodiments of the present application is described in detail below in combination with the drawings and some embodiments and application scenarios.

[0067] Please refer to FIG. 2, which is a flowchart of an LCP processing method provided by an embodiment of the present application. The method can be executed by a terminal, as shown in FIG. 2, and includes the following steps:

[0068] In step 201, the terminal executes a first operation in the case of receiving an uplink grant. The first operation includes at least one of the following:

[0069] If there is an LCH that meets the delay condition among the selected LCHs in the case of executing the LCP procedure by using the first LCP parameter, the LCP procedure is executed by using a second LCP parameter.

[0070] The resources are allocated to at least two LCHs in a first proportion. The at least two LCHs have the same priority, and there is an association relationship between the at least two LCHs.

[0071] If there is an LCH that meets the delay condition among the selected LCHs in the case of executing the LCP procedure by using the first LCP parameter, the LCP procedure is executed by using a second LCP parameter. For example, if there is an LCH that meets the delay condition among the selected LCHs in the case of executing the LCP procedure by using the first LCP parameter, the LCP parameter is adjusted, and the LCP procedure is executed by using the adjusted LCP parameter. The second LCP parameter is the adjusted LCP parameter. The adjustment of the LCP parameter can include at least one of the following: adjustment of the LCP mapping limit and adjustment of the LCP priority order. That is, there can be at least one different parameter between the first LCP parameter and the second LCP parameter: the LCP mapping limit and the LCP priority order.

[0072] In a case where the terminal receives an uplink grant, the terminal can select LCHs according to a first LCP mapping restriction configured by the network-side device, and then can perform delay monitoring on each of the selected LCHs, i.e., monitoring whether the selected LCHs meet a delay condition. For example, the delay condition can include, but is not limited to, a remaining time of a PDB of a data packet of the LCH being less than or equal to a first threshold, a remaining time of a packet set delay budget (PSDB) of a data packet set of the LCH being less than or equal to a third threshold, or a remaining time of a relative delay budget (RDB) corresponding to the LCH being less than or equal to a fifth threshold. In a case where there is an LCH that meets the delay condition, the terminal can adjust an LCP parameter, for example, can increase a priority of the LCH that meets the delay condition, or can adjust the LCP mapping restriction, and obtain a second LCP parameter. Then, the terminal can perform an LCP procedure based on the second LCP parameter. For example, if the priority of the LCH is adjusted, the terminal can perform resource allocation based on the adjusted priority order of the LCH. If the LCP mapping restriction is adjusted, the terminal can select LCHs based on the adjusted LCP restriction in a case where a new uplink grant is received.

[0073] In a case where priorities of at least two LCHs having an association relationship in the LCHs selected by the terminal are the same, when it is the turn of the at least two LCHs to be allocated resources in the LCP procedure, the terminal can allocate resources to the at least two LCHs according to a first ratio, so that a relative delay between the at least two LCHs meets a relative delay requirement. For example, in a case where the at least two LCHs include two LCHs, and the first ratio is 1:3, if there is an uplink grant of 1000B when it is the turn of the two LCHs to be allocated resources, the terminal can allocate 250B to one LCH and 750B to the other LCH according to the ratio of 1:3.

[0074] The first ratio can be a ratio configured by the network-side device, or the first ratio can be a ratio determined by the terminal. For example, the terminal can determine the first ratio according to data amounts of the at least two LCHs under a guaranteed rate.

[0075] The at least two LCHs can be any two LCHs having an association relationship in the selected LCHs. The first LCH and the second LCH have an association relationship, for example, the at least two LCHs are LCHs corresponding to two QoS flows having an association relationship. The two QoS flows having an association relationship can be two QoS flows associated with the same multi-modality service identifier (MMSID).

[0076] In the embodiments of the present application, if there is an LCH that meets the delay condition in the selected logical channel LCH when the LCP procedure is performed using the first LCP parameter, the LCP procedure is performed using the second LCP parameter, which is beneficial to make the LCH that meets the delay condition be transmitted preferentially. For at least two LCHs with the same priority, resources are allocated to the at least two LCHs according to the first proportion, which is beneficial to make the relative delay between the at least two LCHs meet the relative delay requirement, and thus the situation that the service data transmission does not meet the delay requirement can be reduced.

[0077] Optionally, the selected LCH includes a first LCH that meets the delay condition. The first LCH meeting the delay condition includes at least one of the following:

[0078] A remaining time of a packet delay budget PDB of a data packet of the first LCH is less than or equal to a first threshold, or a delay of the data packet of the first LCH is greater than or equal to a second threshold;

[0079] A remaining time of a packet set delay budget PSDB of a data packet set of the first LCH is less than or equal to a third threshold, or a delay of the data packet set of the first LCH is greater than or equal to a fourth threshold;

[0080] A remaining time of a relative delay budget RDB between a first object and a second object of the first LCH is less than or equal to a fifth threshold, or a relative delay between the first object and the second object of the first LCH is greater than or equal to a sixth threshold;

[0081] The delay of the data packet of the first LCH is greater than or equal to the PDB, or a first timer corresponding to the data packet of the first LCH is overdue, and a timing duration of the first timer is equal to the PDB;

[0082] The delay of the data packet set of the first LCH is greater than or equal to the PSDB, or a second timer corresponding to the data packet set of the first LCH is overdue, and a timing duration of the second timer is equal to the PSDB;

[0083] a relative delay between the first object and a second object of the first LCH is greater than or equal to the RDB, or a third timer corresponding to the first object of the first LCH expires, a timing duration of the third timer being equal to the RDB;

[0084] The second object is an object of a second LCH, the first object and the second object have an association relationship, and the second object is preferentially transmitted than the first object. The first object or the second object includes a data packet, a data packet set, a quality of service (QoS) flow, a logical channel, or an RB.

[0085] In the embodiment, the first LCH can be any LCH in the selected LCHs.

[0086] For the remaining time of the PDB of the data packet of the first LCH, a first timer, for example, a discard timer, can be started when the data packet is received from a higher layer, and the timing duration of the first timer is equal to the PDB. The remaining time of the PDB of the data packet of the first LCH can be the remaining time until the first timer expires (for example, remaining time till discardTimer expiry). It can be understood that the remaining time of the PDB of the data packet of the first LCH can be the time difference between the current time and the expiration of the first timer, wherein the current time can be the time when it is judged whether the first LCH meets the delay condition.

[0087] For the remaining time of the PSDB of the data packet set of the first LCH, a second timer can be started when the first data packet or the last data packet of the data packet set is received from a higher layer, and the timing duration of the second timer is equal to the PDB. The remaining time of the PSDB of the data packet set of the first LCH can be the remaining time until the second timer expires. It can be understood that the remaining time of the PSDB of the data packet set of the first LCH can be the time difference between the current time and the expiration of the second timer, wherein the current time can be the time when it is judged whether the first LCH meets the delay condition.

[0088] For the remaining time of the RDB between the first object and the second object of the first LCH, a third timer can be started when the second object associated with the first object of the first LCH is scheduled, and the timing duration of the third timer is equal to the RDB. The remaining time of the RDB between the first object and the second object of the first LCH can be the remaining time until the third timer expires. It can be understood that the RDB between the first object and the second object of the first LCH can be the time difference between the current time and the expiration of the third timer, wherein the current time can be the time when it is judged whether the first LCH meets the delay condition.

[0089] For the first timer corresponding to the data packet of the first LCH, the first timer can be started in a case that the data packet is received from the higher layer, and the first timer is considered to be overdue in a case that a timing duration of the first timer reaches the PDB.

[0090] For the second timer corresponding to the data packet set of the first LCH, the second timer can be started in a case that a first data packet or a last data packet of the data packet set is received from the higher layer, and the second timer is considered to be overdue in a case that a timing duration of the second timer reaches the PSDB.

[0091] For the third timer corresponding to the first object of the first LCH, the third timer can be started in a case that a second object having an association relationship with the first object is scheduled, and the third timer is considered to be overdue in a case that a timing duration of the third timer reaches the RDB.

[0092] It should be noted that at least one of the PDB, the RDB, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold and the sixth threshold can be configured by the network side device.

[0093] Optionally, the first LCP parameter includes at least one of the following: a first LCH priority order, a first LCP mapping limit.

[0094] And / or,

[0095] The second LCP parameter includes at least one of the following: a second LCH priority order, a second LCP mapping limit.

[0096] For the same LCH in the first LCH priority order and the second LCH priority order, the priority of at least part of the LCHs is different. For example, for the LCHs satisfying the delay condition, the priority of the first LCH in the first LCH priority order is different from the priority of the first LCH in the second LCH priority order, for example, the priority of the first LCH satisfying the delay condition in the first LCH priority order is lower than the priority of the first LCH satisfying the delay condition in the second LCH priority order; for the LCHs not satisfying the delay condition, the priority of the first LCH in the first LCH priority order can be the same as the priority of the first LCH in the second LCH priority order.

[0097] Exemplarily, the second LCP parameter can be an adjusted LCP parameter. It should be noted that, in the case that the first LCP parameter comprises a first LCH priority order and the second LCP parameter comprises a second LCH priority order, it is indicated that the LCH priority order is adjusted; in the case that the first LCP parameter comprises a first LCP mapping restriction and the second LCP parameter comprises a second LCP mapping restriction, it is indicated that the LCP mapping restriction is adjusted; in the case that the first LCP parameter comprises a first LCH priority order and a first LCP mapping restriction and the second LCP parameter comprises a second LCH priority order and a second LCP mapping restriction, it is indicated that the LCH priority order and the LCP mapping restriction are both adjusted.

[0098] Exemplarily, in the case that there is a first LCH satisfying the delay condition in the LCH selected based on the first LCP mapping restriction, the priority of the first LCH can be adjusted, for example, the priority of the first LCH can be adjusted to a target priority, the target priority can be a preconfigured or predefined priority; or the priority of the first LCH can be adjusted by M levels, M being a preconfigured or predefined value, so that the first LCH can be preferentially allocated resources in the LCP process; or the LCP mapping restriction can be adjusted, for example, the network side device can configure at least two LCP mapping restrictions for the terminal, in the case that an uplink grant is received, the terminal can select a LCH according to a first LCP mapping restriction in the at least two LCP mapping restrictions, in the case that there is a LCH satisfying the delay condition in the selected LCH, the second LCP mapping restriction in the at least two LCP mapping restrictions can be used to select a LCH. It can be understood that, in the case that the priority of the first LCH is adjusted, the LCH priority order is correspondingly adjusted.

[0099] Optionally, if there is a LCH satisfying the delay condition in the logical channel LCH selected in the case that the LCP process is performed by using the first LCP parameter, the LCP process is performed by using the second LCP parameter, comprising:

[0100] If there is a LCH satisfying the delay condition in the LCH selected by using the first LCP mapping restriction, the first LCP process is performed;

[0101] The first LCP process comprises:

[0102] The first LCH priority order is used to allocate resources for the selected LCH;

[0103] In the case that there is remaining resource after the resources are allocated for the LCHs based on the first LCH priority order, the second LCH priority order is used to allocate resources for the selected LCH.

[0104] In this embodiment, in the first round of resource allocation of the LCP process, the selected LCHs can be allocated resources based on the priority order before adjustment (i.e., the first LCH priority order); after the first round of resource allocation is completed, if there is still remaining resources, in the second round of resource allocation of the LCP process, the selected LCHs can be allocated resources based on the adjusted priority order (i.e., the second LCH priority order), so as to not only ensure the transmission of delay-sensitive data (i.e., the data of the LCHs meeting the delay condition), but also reduce the impact of the priority adjustment of the LCHs meeting the delay condition on the data transmission of some high-priority LCHs.

[0105] It should be noted that in each round of resource allocation of the LCP process, each LCH can be allocated resources according to Bj of each LCH, where Bj can refer to the related description of the foregoing embodiments, which will not be repeated here. In addition, in the case that there is no remaining resource after the LCHs are allocated resources based on the first LCH priority order, the LCP process can be ended.

[0106] Exemplarily, the following will be illustrated in combination with FIG. 3:

[0107] Referring to FIG. 3, the LCP processing method provided by the embodiment includes the following steps:

[0108] In step 301, the UE receives an uplink grant and has data to be transmitted.

[0109] In step 302, the UE determines whether the timers such as PDB, PSDB or RDB are overdue.

[0110] In this step, if the timers such as PDB, PSDB or RDB are overdue, step 303 can be performed; otherwise, step 305 can be performed.

[0111] In step 303, Bj data volume resource allocation is completed according to the initial LCH priority, and it is determined whether there is remaining resource.

[0112] In this step, the initial LCH priority can be understood as the LCH priority before the LCH priority adjustment, i.e., the first LCH priority order described above.

[0113] In this step, if there is remaining resource after the first round of resource allocation, step 304 can be performed; otherwise, the LCP process can be ended.

[0114] In step 304, the remaining data volume is allocated resources according to the adjusted LCH priority.

[0115] In the second round of resource allocation, the remaining data volume of the LCHs can be allocated resources according to the adjusted LCH priority.

[0116] Step 305, performing a traditional LCP process.

[0117] The traditional LCP process described above can be understood as a related art LCP process.

[0118] Step 306, LCP ends.

[0119] Optionally, the method further comprises:

[0120] If data of the LCH satisfying the delay condition is not transmitted after performing the first LCP process for N times in succession, the terminal performs a second LCP process upon receiving a new uplink grant;

[0121] wherein N is a positive integer, and the second LCP process comprises at least one of the following:

[0122] selecting the LCH based on the second LCP mapping restriction;

[0123] allocating resources to the selected LCH based on the second LCH priority order.

[0124] The N described above can be configured by a network side device or predefined by a protocol.

[0125] In the embodiment, if data of the LCH whose priority is promoted is not transmitted after the first LCP process for N times in succession, the terminal can perform resource allocation using the second priority order from the first round of resource allocation of the LCP process upon receiving an uplink grant next time, for example, adjusting the priority of the LCH satisfying the delay condition from the first round of resource allocation of the LCP process, and performing resource allocation based on the adjusted LCH priority order; or enabling the second LCP mapping restriction to select the LCH, which is conducive to transmitting data of the LCH satisfying the delay condition as soon as possible.

[0126] It should be noted that data of the LCH satisfying the delay condition in different first LCP processes can be the same or different, which is not limited in the embodiment.

[0127] Optionally, the method further comprises:

[0128] In a case where the adjusted priority of the third LCH is the same as the priority of the fourth LCH, the terminal preferentially allocates resources to the third LCH or preferentially allocates resources to the fourth LCH;

[0129] wherein the third LCH is an LCH of the selected LCHs whose priority is adjusted, and the fourth LCH is an LCH of the selected LCHs whose priority is not adjusted.

[0130] Exemplarily, the third LCH is an LCH satisfying the latency condition among the selected LCHs, in which case the priority of the third LCH is adjusted; and the fourth LCH is an LCH not satisfying the latency condition among the selected LCHs, in which case the terminal can not adjust the priority of the fourth LCH. It can be understood that, in the case where the priority of the third LCH is adjusted, the LCH priority order is adjusted accordingly, i.e., the LCH priority order is adjusted from the first LCH priority order to the second LCH priority order.

[0131] For example, the remaining time of the PDB of the data packet of the fourth LCH can be greater than the first threshold, the remaining time of the PSDB of the data packet set of the fourth LCH can be greater than the third threshold, or the remaining time of the RDB corresponding to the object of the fourth LCH can be greater than the fifth threshold.

[0132] In the embodiment, in the case where the adjusted priority of the third LCH is the same as the priority of the fourth LCH, the third LCH after the priority adjustment can be transmitted preferentially to ensure the transmission of latency-sensitive data (i.e., the data of the LCH satisfying the latency condition), or the fourth LCH without the priority adjustment can be transmitted preferentially to reduce the impact on the data transmission of the LCH with the originally higher priority.

[0133] Optionally, if there is an LCH satisfying the latency condition among the selected LCHs in the case where the LCP procedure is performed by using the first LCP parameter, the LCP procedure is performed by using the second LCP parameter, including:

[0134] In the case where the uplink grant is received each time, if there is an LCH satisfying the latency condition among the selected LCHs in the case where the LCP procedure is performed by using the first LCP parameter, the LCP procedure is performed by using the second LCP parameter.

[0135] In the embodiment, in the case where the uplink grant is received each time, if there is an LCH satisfying the latency condition among the selected LCHs in the case where the LCP procedure is performed by using the first LCP parameter, the LCP parameter is adjusted, and the LCP procedure can be performed based on the second LCP parameter, i.e., the LCP procedure is performed by using the second LCP parameter; otherwise, the LCP procedure can be performed according to the first LCP parameter. That is, the adjusted LCP parameter each time is only applicable to the LCP procedure of the current transmission, which is conducive to reducing the impact on the transmission of other LCHs while ensuring that the transmission of the LCH satisfying the latency condition meets the latency requirement.

[0136] Optionally, if there is a logical channel LCH that meets the delay condition among the selected LCHs when the LCP procedure is performed by using the first LCP parameter, after the LCP procedure is performed by using the second LCP parameter, the method further includes:

[0137] In a case where data of the LCH that meets the delay condition is all transmitted, or none of the selected LCHs meets the delay condition, the LCP procedure is performed by using the first LCP parameter.

[0138] In the embodiment, if there is a logical channel LCH that meets the delay condition among the selected LCHs when the LCP procedure is performed by using the first LCP parameter, the LCP procedure can be continuously performed by using the second LCP parameter until data of the LCH that meets the delay condition is all transmitted, or none of the selected LCHs meets the delay condition, and in a case where data of the LCH that meets the delay condition is all transmitted, or none of the selected LCHs meets the delay condition, the LCP procedure is performed by using the first LCP parameter again, that is, after the LCP parameter is adjusted, the adjusted LCP parameter (i.e., the second LCP parameter) can be continuously used to perform the LCP procedure in subsequent transmissions until data of the LCH that meets the delay condition is all transmitted, or none of the selected LCHs meets the delay condition, which is beneficial to quickly reduce the case that the service data transmission does not meet the delay requirement.

[0139] Optionally, a packet header of the data packet transmitted based on the second LCP parameter includes a first indication, and the first indication is used to indicate that the data packet is the data packet transmitted based on the second LCP parameter.

[0140] For example, the first indication is indicated by 1 bit of the packet header of the data packet, for example, when the bit is 1, it indicates that the data packet is the data packet transmitted based on the second LCP parameter, and when the bit is 0, it indicates that the data packet is not the data packet transmitted based on the second LCP parameter.

[0141] In the embodiment, the first indication is included in the packet header of the data packet, so that the network can more conveniently indicate that the data packet is the data packet transmitted based on the second LCP parameter.

[0142] Optionally, the method further includes:

[0143] The terminal sends first information to the network side device;

[0144] The first information includes at least one of the following: LCH identification using the second LCP parameter for transmission, the number of times each LCH uses the second LCP parameter for transmission, the data volume of each LCH using the second LCP parameter for transmission, and time information of each LCH using the second LCP parameter for transmission.

[0145] The time information may, for example, include at least one of absolute time of data transmission using the second LCP parameter and duration of data transmission using the second LCP parameter.

[0146] For example, the terminal may, in each transmission, send at least one of the following to the network side device if there is an LCH using the second LCP parameter for transmission: LCH identification (i.e., LCH ID) using the second LCP parameter for transmission, data volume of each LCH using the second LCP parameter for transmission, and time information of each LCH using the second LCP parameter for transmission; or the terminal may, in a period of time, count at least one of the following: LCH using the second LCP parameter for transmission, the number of times each LCH uses the second LCP parameter for transmission, data volume of each LCH using the second LCP parameter for transmission, and time information of each LCH using the second LCP parameter for transmission, and send to the network side device to assist the network side device in adjusting the scheduling algorithm.

[0147] In some optional embodiments, the terminal may send the first information to the network side device through a MAC CE.

[0148] Optionally, the method further includes:

[0149] The terminal receives second information from the network side device, the second information being used to indicate a strategy of adjusting the LCP parameter of the terminal, or the second information including the second LCP parameter.

[0150] For example, the second information may include at least one of the following: M, a target priority, a second LCH priority order, a second LCP mapping limit, etc., where M is a positive integer, M indicates adjusting the LCH priority by M levels, the target priority is used to indicate adjusting the LCH priority to a target priority, the second LCH priority order is used to indicate adjusting the LCH priority order to a second LCH priority order, and the second LCP mapping limit is used to indicate adjusting the LCP mapping limit to a second LCP mapping limit.

[0151] Optionally, the first proportion is a proportion of the first data volume of the at least two LCHs, and the first data volume of the LCH is a data volume to be transmitted at a guaranteed rate or a maximum data volume at a guaranteed rate of the LCH.

[0152] In the embodiment, the data amount to be transmitted of the LCH at the guaranteed rate can be understood as Bj. The maximum data amount of the LCH at the guaranteed rate can be understood as PBR x BSD. The meanings of Bj and PBR x BSD can be referred to the related description in the foregoing embodiment, and will not be described herein.

[0153] Correspondingly, the first ratio can be the ratio of Bj of the at least two LCHs, or the first ratio can be the ratio of PBR x BSD of the at least two LCHs.

[0154] Optionally, the allocating resources to the at least two LCHs according to the first ratio comprises:

[0155] In a case where the resource size required by the second data amount of the at least two LCHs is greater than the current resource size, the terminal allocates resources to the at least two LCHs according to the first ratio.

[0156] The second data amount of the LCH is the data amount to be transmitted of the LCH at the guaranteed rate.

[0157] In the embodiment, in the first round of resource allocation of the LCP process, in a case where the current resource is insufficient to be allocated to the at least two LCHs, the resources can be allocated to the at least two LCHs according to the first ratio, which is beneficial to guarantee that the relative delay requirements among the at least two LCHs are met.

[0158] Optionally, the method further comprises:

[0159] In a case where the resource size required by the second data amount of the at least two LCHs is less than or equal to the current resource size, the terminal allocates resources to each LCH of the at least two LCHs required by the second data amount corresponding to each LCH.

[0160] In a case where there is remaining resource after the resources are allocated to the selected LCHs, if the resource size required by the remaining data amount of the at least two LCHs is greater than the size of the remaining resource, the terminal allocates resources to the at least two LCHs according to a second ratio.

[0161] The remaining data amount of the LCH can be understood as the newly added data amount after the resources required by the second data amount of the LCH are allocated, wherein the remaining data amount of the LCH can be PBR x t, PBR represents the priority bit rate of the LCH, and t represents the interval from the previous allocation of resources to the LCH to the current time.

[0162] Optionally, the second ratio is a ratio of a priority bit rate (PBR) of the at least two LCHs, or the second ratio is a ratio configured by the network-side device, or the second ratio is a ratio predefined by a protocol.

[0163] Exemplarily, in the first round of resource allocation of the LCP process, in a case where the current resources are sufficient to be allocated to the at least two LCHs, the terminal can allocate resources for all data (i.e., data of the second data amount) currently transmittable by the at least two LCHs; after the first round of resource allocation is completed, if there are still remaining resources, a second round of resource allocation of the LCP process can be performed, if the current remaining resources are insufficient to be allocated to the at least two LCHs, the terminal can allocate resources for the at least two LCHs according to the second ratio; if the current remaining resources are sufficient to be allocated to the at least two LCHs, the terminal can allocate resources for all data (i.e., data of the remaining data amount) remaining transmittable by the at least two LCHs.

[0164] It should be noted that each round of resource allocation of the LCP process is performed in a descending order of LCH priority.

[0165] The embodiment allocates resources for the at least two LCHs according to the second ratio in a case where the current remaining resources are insufficient to be allocated to the remaining data amount of the at least two LCHs, which is beneficial to guarantee that the relative delay requirements among the at least two LCHs are met.

[0166] The following takes two LCHs as an example to describe the embodiment.

[0167] Referring to FIG. 4, the LCP processing method provided by the embodiment includes the following steps:

[0168] Step 401: The UE receives an uplink grant and has data to be transmitted.

[0169] Step 402: It is the turn to allocate resources for two LCHs with the same priority and having an association relationship.

[0170] The two LCHs having the association relationship are, for example, LCHs associated with the same MMSID.

[0171] Step 403: In the first round of resource allocation, it is determined whether Bj1 and Bj2 of the two LCHs can all be allocated resources.

[0172] In this step, if Bj1 and Bj2 of the two LCHs can all be allocated resources, step 405 is performed, otherwise, step 404 is performed.

[0173] Step 404, allocating resources for the two LCHs according to the ratio of Bj1 and Bj2.

[0174] Step 405, allocating resources required by Bj1 and Bj2 for the two LCHs.

[0175] Step 406, determining whether there is remaining resource after the first round of resource allocation and whether there is remaining data volume of the two LCHs to be transmitted.

[0176] In this step, if there is remaining resource after the first round of resource allocation and there is remaining data volume of the two LCHs to be transmitted, step 407 can be performed, otherwise the LCP procedure can be ended or the remaining resource can be allocated to other LCHs with remaining data volume to be transmitted.

[0177] Step 407, determining whether the remaining data volume of the two LCHs can all be allocated resources in the second round of resource allocation.

[0178] In this step, if the remaining data volume of the two LCHs can all be allocated resources, step 408 is performed, otherwise step 409 can be performed.

[0179] Step 408, allocating resources required by the remaining data volume for the two LCHs.

[0180] Step 409, allocating resources for the two LCHs according to a second ratio.

[0181] The second ratio can refer to the related description of the foregoing embodiments, which will not be repeated here.

[0182] Step 410, ending the LCP.

[0183] Optionally, the at least two LCHs include a fifth LCH and a sixth LCH, and the allocating resources for the at least two LCHs according to the first ratio includes:

[0184] allocating resources for the fifth LCH and the sixth LCH according to the first ratio in a case where the fifth LCH and the sixth LCH satisfy a first condition;

[0185] or,

[0186] allocating resources for the fifth LCH and the sixth LCH according to the first ratio in a case where the fifth LCH and the sixth LCH do not satisfy the first condition;

[0187] The fifth LCH and the sixth LCH satisfy the first condition include one of the following:

[0188] a relative latency of a fifth object of the fifth LCH and a sixth object of the sixth LCH is greater than or equal to RDB;

[0189] a relative latency of a fifth object of the fifth LCH and a sixth object of the sixth LCH is greater than or equal to a sixth threshold;

[0190] a residual time of an RDB of the fifth object of the fifth LCH and the sixth object of the sixth LCH is less than or equal to a fifth threshold;

[0191] the fifth object or the sixth object comprises a data packet, a data packet set, or a QoS flow or a logical channel or an RB.

[0192] In an embodiment, in a case where the fifth LCH and the sixth LCH satisfy a first condition, resources are allocated to the fifth LCH and the sixth LCH in a first proportion; in a case where the fifth LCH and the sixth LCH do not satisfy the first condition, resources can be allocated to the at least two LCHs in a manner of resource allocation of a related art LCP procedure, for example, resources are equally allocated to the at least two LCHs depending on terminal implementation.

[0193] In another embodiment, in a case where the fifth LCH and the sixth LCH do not satisfy the first condition, resources are allocated to the fifth LCH and the sixth LCH in the first proportion; in a case where the fifth LCH and the sixth LCH satisfy the first condition, resources can be preferentially allocated to a slower LCH among the at least two LCHs to ensure that a relative latency requirement is satisfied between the at least two LCHs.

[0194] Optionally, the method further comprises:

[0195] in a case where the fifth LCH and the sixth LCH satisfy the first condition, the terminal preferentially allocates resources to a target LCH until the fifth LCH and the sixth LCH do not satisfy the first condition, the target LCH being a slower LCH among the fifth LCH and the sixth LCH;

[0196] wherein, in a case where the fifth LCH and the sixth LCH do not satisfy the first condition, resources are allocated to the fifth LCH and the sixth LCH in the first proportion.

[0197] Exemplarily, a slower LCH among the fifth LCH and the sixth LCH can be determined by comparing and For example, if indicates that the sixth LCH is the slower LCH, the target LCH is the sixth LCH; if the fifth LCH is the target LCH; wherein, X represents the PBR of the QoS flow corresponding to the fifth LCH, Y represents the PBR of the QoS flow corresponding to the sixth LCH, x1 represents the transmission rate of the QoS flow corresponding to the fifth LCH, and y1 represents the transmission rate of the QoS flow corresponding to the sixth LCH. Alternatively, the LCH with slower transmission among the fifth LCH and the sixth LCH can be determined according to the time when the two data packets or data packet sets of the fifth LCH and the sixth LCH having the association relationship are scheduled, for example, if the first data packet or the first data packet set of the fifth LCH is scheduled earlier than the second data packet or the second data packet set of the sixth LCH, the sixth LCH is the target LCH; if the second data packet or the second data packet set of the sixth LCH is scheduled earlier than the first data packet or the first data packet set of the fifth LCH, the fifth LCH is the target LCH. The second data packet and the first data packet are two data packets having the association relationship, and the second data packet set and the first data packet set are two data packet sets having the association relationship.

[0198] In the embodiment, in the case where the fifth LCH and the sixth LCH satisfy the first condition, the terminal can preferentially allocate resources to the LCH with slower transmission among the fifth LCH and the sixth LCH until the fifth LCH and the sixth LCH do not satisfy the first condition, and then resume allocating resources to the fifth LCH and the sixth LCH according to the first proportion, which is beneficial to speed up the satisfaction of the relative delay requirement between at least two LCHs.

[0199] In some optional embodiments, in the case where the fifth LCH and the sixth LCH satisfy the first condition, the terminal preferentially allocates resources to the target LCH until the fifth LCH and the sixth LCH do not satisfy the first condition, and then can exit the scheduling optimization process, for example, can perform resource allocation according to the resource allocation manner of the LCP process of the related art.
