Description

Method and terminal equipment for allocating resources for uplink logical channel

Technical Field

The present application relates to the field of communications, and in particular, to a method and a terminal device for allocating resources for an uplink logical channel.

Background

Aiming at the characteristic of large transmission delay of wireless signals between a terminal and a satellite in a Non-Terrestrial Network (NTN) system, introduction of a Hybrid Automatic Repeat Request (HARQ) function to be enabled to reduce data transmission delay is discussed in an NTN standardization process, and transmission reliability can be ensured through Radio Link Control (RLC) Automatic Repeat Request (ARQ) retransmission under the condition that the HARQ function is disabled. Therefore, it is necessary to study how to reduce the RLC retransmission delay.

RLC retransmissions are triggered by RLC status reports, which are transmitted on a Physical Uplink Shared Channel (PUSCH) or a Physical Downlink Shared Channel (PDSCH).

For downlink transmission, the network can transmit the RLC status report preferentially by improving the priority of the RLC status report during scheduling, thereby reducing the scheduling delay of the RLC status report and triggering RLC retransmission as early as possible.

For uplink transmission, since the network allocates PUSCH resources based on the terminal, and which logical channels to transmit on the resources allocated by the network are determined by the terminal, how to reasonably perform logical channel multiplexing by the terminal is a problem to be solved urgently at present.

Currently, the third Generation Partnership Project (3 GPP) is studying NTN technology, and the NTN generally provides communication services to terrestrial users by means of satellite communication. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communication is not limited by user regions, for example, general terrestrial communication cannot cover regions where communication equipment cannot be set up, such as the sea, mountains, desert, and the like, or communication coverage is not performed due to sparse population, and for satellite communication, since one satellite can cover a large ground and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communication. Second, satellite communication has great social value. Satellite communication can be covered in remote mountainous areas, poor and laggard countries or areas with lower cost, so that people in the areas can enjoy advanced voice communication and mobile internet technology, the digital gap between the areas is favorably reduced and developed, and the development of the areas is promoted. Thirdly, the satellite communication distance is long, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites can be generally classified into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, geosynchronous Orbit (GEO) satellites, High-elliptic Orbit (HEO) satellites, and the like, according to the height of the orbits. The main studies at the present stage are LEO and GEO.

LEO satellite altitude ranges from 500km to 1500km, with a corresponding orbital period of about 1.5 hours to 2 hours. The signal propagation delay for inter-user single-hop communications is typically less than 20 ms. Maximum satellite visibility time 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal is not high.

GEO satellites, with an orbital altitude of 35786km, rotate around the earth for a period of 24 hours. The signal propagation delay for inter-user single-hop communications is typically 250 ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form dozens of or even hundreds of beams to cover the ground; one satellite beam may cover a ground area several tens to hundreds of kilometers in diameter.

The NR HARQ mechanism is described below.

NR is provided with a two-level retransmission mechanism: a HARQ mechanism of a Medium Access Control (MAC) layer and an ARQ mechanism of an RLC layer. Retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and is supplemented by the retransmission function of the RLC layer. The HARQ mechanism of the MAC layer can provide fast retransmission and the ARQ mechanism of the RLC layer can provide reliable data transmission.

HARQ uses a Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-wait protocol, the sender sends a Transport Block (TB), and then stops to wait for an acknowledgement. Thus, the sender may stop waiting for an acknowledgement after each transmission, resulting in low user throughput. Therefore, NR uses a plurality of parallel HARQ processes, and when one HARQ process is waiting for acknowledgement information, the transmitting end can continue to transmit data using another HARQ process. These HARQ processes together constitute a HARQ entity that incorporates a stop-and-wait protocol, allowing for continuous transmission of data. HARQ has a difference between uplink HARQ and downlink HARQ. Uplink HARQ is for uplink data transmission and downlink HARQ is for downlink data transmission. The two are independent of each other.

Based on the current specification of the NR protocol, the terminal has a respective HARQ entity for each serving cell. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. Currently, each uplink and downlink carrier supports a maximum of 16 HARQ processes. The base station may indicate the maximum HARQ process number to the UE through Radio Resource Control (RRC) signaling semi-static configuration according to a network deployment situation. If the network does not provide corresponding configuration parameters, the downlink default HARQ process number is 8, and the maximum HARQ process number supported by each uplink carrier is always 16. Each HARQ process corresponds to an HARQ process Identity (ID). For downlink, a Broadcast Control Channel (BCCH) uses a dedicated Broadcast HARQ process. For uplink, Msg3 transmission in the random procedure uses HARQ ID 0.

For a terminal which does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB simultaneously; for a terminal supporting downlink space division multiplexing, each downlink HARQ process may process 1 or 2 TBs simultaneously. Each uplink HARQ process of the terminal processes 1 TB simultaneously.

HARQ is classified into two types, synchronous and asynchronous, in the time domain, and non-adaptive and adaptive, in the frequency domain. The NR uplink and downlink use asynchronous adaptive HARQ mechanisms. Asynchronous HARQ, i.e. retransmission, can occur at any time, and the time interval between the retransmission of the same TB and the last transmission is not fixed. The adaptive HARQ may change the frequency domain resource and the Modulation and Coding Scheme (MCS) used for the retransmission.

The NR ARQ mechanism is introduced below.

There is one RLC entity per logical channel of the UE. An RLC entity may be configured as one of three modes, namely Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). Wherein only AM mode can support error detection and ARQ retransmission.

On the side of the gNB or the UE, one AM entity includes both the receiving side and the transmitting side, i.e., can simultaneously transmit and receive data. The AM entity provides a bi-directional data transfer service.

The AM entity transmits/receives two types of Protocol Data Units (PDUs), namely, RLC Data PDUs and RLC control PDUs. The RLC data PDU is used for transmitting data, and the RLC control PDU is used for transmitting a status report.

For AM RLC entities, by detecting the Sequence Number (SN) of the received RLC data PDU, the receiving end can know which PDUs (or segments thereof) are missing and ask the transmitting end to retransmit the missing PDUs (or segments thereof). The receiver may tell the sender which AMD PDUs were successfully received, and which AMD PDUs or segments have not been successfully received, by sending a status report. After receiving the status report, the transmitting end initiates an ARQ retransmission.

Specifically, there are two scenarios that trigger status reporting: scene 1: the transmitting end initiates polling (polling); scene 2: the Reassembly timer (t-Reassembly) times out, meaning that there is acknowledged mode Data (AM Data, AMD) PDU not received correctly. If an AMD PDU segment is received from the MAC layer and at least one byte (byte) of the corresponding Service Data Unit (SDU) is lost and t-response is not currently running, t-response is started.

Fig. 2 and 3 show RLC control PDUs in two different formats. The RLC control PDU (or RLC status PDU) includes a status report PDU payload (payload) and an RLC status PDU header, as shown in fig. 2 and 3, each line representing 8bytes (Octet, Oct). The RLC status PDU header consists of a Data/Control (D/C) indication field and a Control PDU Type (CPT) indication field, wherein the D/C field is used for indicating whether the PDU is a Data PDU or a Control PDU; the CPT field is used to indicate the category of the RLC PDU.

The status PDU payload may include: one "Acknowledge (ACK) _ SN + E1", 0 or more "not Acknowledge (Non-Acknowledge) _ SN + E1+ E2+ E3" combinations and their possible SOstart (start) and SOend (end) or NACK range fields. Wherein, the "ACK _ SN" corresponds to an SN value of an RLC data PDU that is not reported as lost in the status PDU and has not been received next. When the transmitting end receives a status PDU, the transmitting end considers AMD PDUs with SN < ACK _ SN to have been successfully received by the peer, except for those AMD PDUs indicated by NACK _ SN + E1+ E2+ E3, which are fragmented.

It should be understood that ACK _ SN is set to the SN of the next RLC data PDU that has not been received and is not indicated in the status PDU as missing. The value of ACK _ SN is related to the resource size indicated by the MAC layer. When the resource size indicated by the MAC layer is not large enough to accommodate NACK information for all RLC data PDUs lost within the reception window, the ACK _ SN is set to a value less than or equal to the upper boundary of the reception window.

"NACK _ SN" corresponds to the SN value of an AMD PDU or AMD PDU segment that is deemed missing by the receiving end. NACK _ SN may correspond to a missing AMD PDU or a missing AMD PDU segment. If an AMD PDU is lost, there will be a corresponding "NACK _ SN + E1+ E2+ E3" combination in the status PDU; if an AMD PDU segment is missing, there will be a corresponding combination of "NACK _ SN + E1+ E2+ E3+ SOstart + SOend" in the status PDU. "SOstart" and "SOend" together indicate which part of the AMD PDU with SN NACK _ SN is missing. Where "SOstart" corresponds to the location of the first byte of the lost segment in the Data field of the original AMD PDU and "SOend" corresponds to the location of the last byte of the lost segment in the Data field of the original AMD PDU.

The NR Logical Channel Priority (LCP) processing is described below.

Like LTE, in NR, the network allocates uplink transmission resources on a per user (per-UE) basis rather than on a per bearer basis, and it is up to the UE which radio bearers have data that can be put in the allocated uplink transmission resources for transmission.

Based on the uplink transmission resources configured by the network, the UE needs to determine the transmission Data amount of each logical channel in the initial transmission MAC Protocol Data Unit (PDU), and in some cases, the UE needs to allocate resources for the MAC CE. In order to realize multiplexing of uplink logical channels, a priority needs to be allocated to each uplink logical channel. For a MAC PDU with a given size, under the condition that a plurality of uplink logical channels have data transmission requirements at the same time, resources of the MAC PDU are sequentially distributed according to the descending order of the logical channel priority corresponding to each uplink logical channel. Meanwhile, in order to take fairness among different logical channels into account, probability of Prioritized Bit Rate (PBR) is introduced, and when the UE multiplexes logical channels, it is necessary to first ensure a minimum data Rate requirement of each logical channel, so as to avoid that uplink logical channels with high priority always occupy uplink resources allocated to the UE by the network, which causes other uplink logical channels with low priority of the UE to be starved.

To implement multiplexing of uplink logical channels, the network will typically configure the following parameters for each uplink logical channel through RRC: logical channel priority (priority): the smaller the value of the priority is, the higher the corresponding priority is; PBR, which represents the minimum rate that the logical channel needs to guarantee; token Bucket capacity (Bucket Size Duration, BSD): this parameter determines the depth of the token bucket.

The MAC of the UE uses a token bucket mechanism to implement uplink logical channel multiplexing. Specifically, the UE maintains a variable Bj for each uplink logical channel j, where the variable indicates the number of currently available tokens in the token bucket, and the method includes: when UE establishes a logic channel j, initializing Bj to be 0; before each LCP process, the UE increases the Bj by PBR T, wherein T is the time interval from the previous increase of the Bj to the current time; if Bj updated according to step 2 is greater than the maximum capacity of the token bucket (i.e., PBR BSD), Bj is set to the maximum capacity of the token bucket.

When the UE receives an Uplink (UL) grant (grant) indicating a new transmission, the UE performs LCP processing as follows.

Step 1: and for all the logical channels with Bj >0, allocating resources according to the sequence of the priority from high to low, wherein the resources allocated to each logical channel can only meet the requirement of PBR (provider-base ratio), namely allocating the resources for the logical channel according to the number of tokens in a PBR token bucket corresponding to the logical channel. When the PBR of a certain logical channel is set to infinity, other logical channels with lower priority than the logical channel are considered only when the resources of the logical channel are satisfied.

Step 2: the logical channel j is subtracted from Bj to the size of all MAC Service Data Units (SDUs) multiplexed into the MAC PDU in step 1.

And step 3: if there are remaining uplink resources after

steps

1 and 2 are performed, the remaining resources are sequentially allocated to the logical channels in the order of logical channel priority from high to low regardless of the size of Bj of each logical channel (i.e., regardless of whether it is greater than 0, equal to 0, or less than 0). Only when the data of the logical channel with high priority is sent and the UL grant is not exhausted, the logical channel with low priority can be served. I.e. when the UE maximizes data transmission for the logical channel of high priority.

Meanwhile, the UE should also follow the following principle: if the whole RLC SDU can be filled in the residual resources, the RLC SDU should not be segmented; if the UE segments the RLC SDU in the logical channel, the maximum segment is filled as much as possible according to the size of the residual resource; the UE should maximize the transmission of data; if the UL grant size is greater than or equal to 8bytes and the UE has a data transmission requirement, the UE cannot send only a padding Buffer Status Report (BSR) or only padding.

For different signals and/or logical channels, the following priority order (in order of priority from high to low) needs to be followed when the UE performs LCP processing: Cell-Radio Network Temporary Identifier (C-RNTI) MAC Control Element (CE) or data from UL Common Control Channel (CCCH); configuring an authorized Grant Confirmation (Configured Grant configuration) MAC CE; for BSR MAC CEs other than padding BSRs; a Single Entry (Single Entry) Power Headroom Report (PHR) MAC CE or a Multiple Entry (Multiple Entry) PHR MAC CE; data from any logical channel other than UL-CCCH; a MAC CE for Recommended bit rate query (Recommended bit rate query); BSR MAC CE for padding BSR.

Aiming at the characteristic of larger transmission delay of wireless signals between a terminal and a satellite in an NTN system, the introduction of a de-enabling HARQ function to reduce data transmission delay is discussed in the standardization process of 3GPP to NTN, and the transmission reliability can be ensured through RLC ARQ retransmission under the condition of de-enabling the HARQ function. Therefore, it is necessary to study how to reduce the RLC retransmission delay.

RLC retransmissions are triggered by RLC status reports, which are transmitted on the PUSCH or PDSCH.

For uplink transmission, the network allocates PUSCH resources based on the UE, and which logical channels to transmit on the resources allocated by the network is determined by the UE. Based on the current standard, the UE performs logical channel multiplexing based on the logical channel priority configured by the network, and the main consideration factor of the logical channel priority configuration is the requirement of Quality of Service (QoS). For each logical channel, whether RLC status PDUs or RLC data PDUs need to be transmitted is not distinguished in the logical channel multiplexing process. How to realize the fast transmission of the RLC status PDU needs to make a set of rules from the standard level.

Therefore, the present application provides a method for allocating resources for an uplink logical channel, which can solve the above problem.

Fig. 4 is a schematic flow chart of a method 200 for allocating resources for an uplink logical channel according to an embodiment of the present application. The method 200 may be performed by a terminal device, which may be, for example, the terminal device shown in fig. 1. As shown in fig. 2, the method 200 includes: s210, the terminal device determines the resource allocation priority of at least one uplink logical channel according to the bearer type of the at least one uplink logical channel, wherein the bearer type indicates that the bearer of the uplink logical channel includes an RLC status report and/or data.

Optionally, the method 200 may further include: the terminal equipment determines the bearing type of at least one uplink logical channel. Specifically, the AM entity may transmit/receive two types of PDUs, i.e., RLC data PDU and RLC control PDU, where the RLC data PDU is used to transmit data and the RLC control PDU is used to transmit a status report. Correspondingly, for any uplink logical channel, the uplink logical channel can be used for carrying the RLC status report; or, the uplink logical channel may also be used to carry data; alternatively, the uplink logical channel may also be used to carry RLC status reports and data. Thus, the terminal device determines the bearer type of each logical channel, i.e. determines that each logical channel is used to carry RLC status reports and/or data.

In S210, the terminal device may determine a resource allocation priority of each logical channel according to the bearer type of each logical channel, where the resource allocation priority is used to indicate a sequence of allocating resources for each logical channel.

As shown in fig. 2, the method 200 further includes: s220, the terminal device allocates uplink resources to the at least one uplink logical channel according to the resource allocation priority of the at least one uplink logical channel. Specifically, the terminal device determines resource allocation priorities of different logical channels according to different bearer types of the different logical channels; and allocating uplink resources for different logical channels in sequence according to different resource allocation priorities. The uplink resource may be any uplink resource, for example, the uplink resource may be a UL grant received by the terminal device and indicated by the network device, or may also be other uplink resources. The following description will be made in detail in connection with several different scenarios.

Optionally, as a first embodiment, the terminal device may set the resource allocation priority of the RLC status report corresponding to the uplink logical channel to be greater than or equal to the resource allocation priority of the data corresponding to the uplink logical channel; in addition, when allocating uplink resources, the allocation is roughly completed in two rounds, and for each round of resource allocation, resources are allocated to each uplink logical channel corresponding to the RLC status report first, and then resources are allocated to each uplink logical channel corresponding to data.

Specifically, S210 in the embodiment of the present application may include: the terminal equipment determines a first uplink logical channel set and a second uplink logical channel set in at least one uplink logical channel according to the bearing type of the at least one uplink logical channel, wherein the bearing of each uplink logical channel in the first uplink logical channel set comprises an RLC (radio link control) state report, and the bearing of each uplink logical channel in the second uplink logical channel set comprises data; the terminal equipment determines that the resource allocation priority of the uplink logical channel in the first uplink logical channel set is higher than the resource allocation priority of the uplink logical channel in the second uplink logical channel set.

That is, the terminal device divides the logical channels into two sets, and for any uplink logical channel in at least one uplink logical channel, if the uplink logical channel corresponds to the RLC status report to be transmitted, the uplink logical channel belongs to the first uplink logical channel set; if the uplink logical channel corresponds to data to be transmitted, the uplink logical channel belongs to a second uplink logical channel set; if the uplink logical channel has the RLC status report to be transmitted and the data to be transmitted at the same time, the uplink logical channel is the first uplink logical channel set and also belongs to the second uplink logical channel set. That is, there may be an uplink logical channel belonging to both the first uplink logical channel set and the second uplink logical channel set in the at least one uplink logical channel.

The terminal device determines that the resource allocation priority of the uplink logical channel in the first uplink logical channel set is higher than or equal to the resource allocation priority of the uplink logical channel in the second uplink logical channel set, and then the terminal device may allocate uplink resources to at least one uplink logical channel according to the sequence of the resource allocation priorities.

Specifically, the uplink resource allocation process can be roughly divided into two rounds, and each round can be further divided into two stages. First, a first round of resource allocation procedure is described, which may further include a first phase and a second phase. For the first stage, the terminal device sequentially allocates the uplink resources to the uplink logical channels in the first uplink logical channel set according to the order from high to low of the configuration priority of each uplink logical channel in the first uplink logical channel set, where, when allocating the uplink resources to any one uplink logical channel in the first uplink logical channel set, for example, any one uplink logical channel in the first uplink logical channel set is referred to as a first uplink logical channel here, and the resources allocated to the first uplink logical channel meet a first requirement, where the first requirement is: the resource allocated for the first uplink logical channel satisfies the requirement of the size of the minimum PDU of the RLC status report included in the first uplink logical channel.

It should be understood that, for any uplink logical channel of the terminal device, the network device may configure a logical channel priority (priority) for the uplink logical channel, for example, the smaller the value of the priority, the higher the priority of the corresponding logical channel. To distinguish from the resource allocation priority, this priority of the network device configuration is referred to herein as the configuration priority of the logical channel.

Optionally, the method 200 may further include: the terminal equipment receives RRC information sent by the network equipment, wherein the RRC information comprises at least one of the following parameters: the configuration priority of the at least one uplink logical channel, the PBR of the at least one uplink logical channel, and the token bucket capacity BSD of the at least one uplink logical channel.

For the second stage, after the resource allocation of the first stage is completed, that is, after the uplink resource is allocated to each uplink logical channel in the first uplink logical channel set in sequence according to the first requirement, if there are remaining resources, the first round of resource allocation for logical channel data is continuously performed, that is, for all uplink logical channels in the second uplink logical channel set where Bj >0, the resources are allocated in sequence from high to low in priority, and the resources allocated to each uplink logical channel can only meet the requirement of PBR.

Specifically, the remaining resources existing in the uplink resources are referred to as first uplink resources, and then in the second stage, the terminal device sequentially allocates the first uplink resources to the uplink logical channels in the second uplink logical channel set, where the token number Bj is greater than 0, according to the PBR requirement and in the order from high to low of the configuration priority of each uplink logical channel in the second uplink logical channel set. Wherein, the PBR requirement is as follows: and the resource allocated to the second uplink logical channel meets the PBR requirement of the second uplink logical channel, and the second uplink logical channel is any uplink logical channel with the token number Bj being greater than 0 in the second uplink logical channel set.

For the second stage in the first round of resource allocation process, allocating the uplink logical channel j to the resource, and subtracting the size of all the MAC SDUs multiplexed to the MAC PDU by the logical channel j from the token number Bj of the uplink logical channel j.

After the two phases of the first round of resource allocation are completed, that is, after the first uplink resource is allocated to each uplink logical channel in the second uplink logical channel set in which the token number Bj is greater than 0 in sequence according to the PBR requirement, if there are still remaining resources, the second round of resource allocation process is continued to be performed, where the second round of resource allocation process may further include a third phase and a fourth phase. For the third phase, the second round of resource allocation for RLC status reporting continues. Specifically, the resource remaining after the allocation of the first uplink resource is referred to as a second uplink resource, and the terminal device sequentially allocates the second uplink resource to the uplink logical channels in the first uplink logical channel set according to the order from high to low of the configuration priority of each uplink logical channel in the first uplink logical channel set. And only when the RLC status PDUs of the uplink logical channels with high configuration priorities are completely sent and the uplink resources are not exhausted, the resources can be allocated to the RLC status PDUs of the uplink logical channels with low configuration priorities. That is, the terminal device maximizes the transmission of RLC status PDUs of the uplink logical channel with high configuration priority.

After the resource allocation in the third stage is completed, that is, after the second uplink resource is allocated to each uplink logical channel in the first uplink logical channel set in sequence, if there are still remaining uplink resources, the remaining resources are allocated to the uplink logical channels in sequence from high to low according to the configuration priority of the uplink logical channel, regardless of the size of Bj. Specifically, the resource remaining after the allocation of the second uplink resource is referred to as a third uplink resource, and if the remaining third uplink resource exists in the second uplink resource, the terminal device sequentially allocates the third uplink resource to the uplink logical channels in the second uplink logical channel set according to the order from high to low of the configuration priority of each uplink logical channel in the second uplink logical channel set.

The first embodiment described above will be described below by way of example with reference to the accompanying drawings.

Fig. 5 is a schematic diagram illustrating a method for multiplexing an uplink logical channel according to an embodiment of the present application. As shown in fig. 5, it is assumed here that the UE establishes 4 uplink Logical Channels (LCs), which are respectively referred to as LC1, LC2, LC3 and LC 4. In addition, the UE receives the RRC configuration sent by the network device, and according to the RRC configuration, the terminal device determines that the order of the configuration priorities of the 4 logical channels is LC1> LC2> LC3> LC4, and meanwhile, the terminal device may also determine the PBR and BSD of each uplink logical channel.

When the UE receives the UL grant indication uplink initial transmission from the network, as shown in fig. 5, the UE completes logical channel multiplexing according to the following steps.

Step 1, determining candidate logical channels of the current uplink transmission.

Assuming that the current LC2 and LC3 have RLC status reports to be transmitted, the first uplink logical channel set of the current uplink transmission includes LC2 and LC 3; assuming that all of the current LCs 1, the current LCs 2 and the current LCs 4 have data to transmit, the second set of uplink logical channels for uplink transmission includes LCs 1, LCs 2 and LCs 4. And the resource allocation priority of the LC2 and the LC3 in the first uplink logical channel set is higher than that of the LC1, the LC2 and the LC4 in the second uplink logical channel set.

And 2, executing a first round of resource allocation according to the resource allocation priorities and the configuration priorities of the four uplink logical channels, wherein the step 2 specifically comprises a step 2.1 and a step 2.2.

And 2.1, firstly, sequentially allocating resources for RLC status reports of LC2 and LC3 according to the size of the minimum RLC status PDU.

And 2.2, after the step 2.1 is completed, if the residual resources exist and the token numbers Bj of the LC1, the LC2 and the LC4 are all greater than 0, allocating the resources meeting the PBR for the LC1, the LC2 and the LC4 in sequence, and updating the token numbers in the PBR token buckets of the LC1, the LC2 and the LC4 according to the resource allocation result.

And 3, after the first round of resource allocation is finished, if the residual resources exist, continuing to execute the second round of resource allocation. This step 3 may specifically comprise a step 3.1 and a step 3.2.

And 3.1, sequentially allocating resources for RLC status reports of the LC2 and the LC3 according to the size requirement of the actual RLC status PDU.

And 3.2, after the step 3.1 is finished, if the residual resources exist, allocating the residual resources to the LC1, the LC2 and the LC4 in sequence according to the residual data quantity and the residual resource quantity. As shown in fig. 5, when the resource allocation to LC1 and LC2 is completed, assuming that there are no resources left, the resource allocation to LC4 is not continued; but if, in contrast, the resources are sufficient, the LC4 may continue to be allocated resources.

Optionally, as a second embodiment, similar to the first embodiment, the terminal device may set the resource allocation priority of the RLC status report corresponding to the uplink logical channel to be greater than or equal to the resource allocation priority of the data corresponding to the uplink logical channel; however, when allocating uplink resources, the terminal device allocates resources to data corresponding to each uplink logical channel after completing resource allocation to RLC status reports corresponding to all uplink logical channels.

Specifically, the same as the first embodiment is: the terminal device determines a first uplink logical channel set and a second uplink logical channel set in the at least one uplink logical channel, and determines that the resource allocation priority of the uplink logical channel in the first uplink logical channel set is higher than the resource allocation priority of the uplink logical channel in the second uplink logical channel set, which is not described herein again for brevity.

The second embodiment is different from the first embodiment in the resource allocation procedure. Specifically, in the second embodiment, the uplink resource allocation process is roughly divided into two rounds, where the first round is resource allocation for a first uplink logical channel set, that is, the terminal device allocates the uplink resource to the uplink logical channel in the first uplink logical channel set according to the configuration priority of each uplink logical channel in the first uplink logical channel set; in the second round, resource allocation is performed on the second uplink logical channel set, that is, after the first round of resource allocation is performed, if there are remaining uplink resources, the terminal device allocates uplink resources to the uplink logical channels in the second uplink logical channel set according to the configuration priority of each uplink logical channel in the second uplink logical channel set.

First, a first round of resource allocation procedure is described, which may further include a first phase and a second phase. And for the first stage, sequentially allocating resources for the RLC status reports of the uplink logical channels according to the size of the minimum RLC status PDU according to the sequence from high to low of the configuration priority of each uplink logical channel in the first uplink logical channel set. Specifically, the first stage is the same as the first stage in the first round of resource allocation process described in the first embodiment, and for brevity, no further description is provided here.

For the second stage, after the resource allocation of the first stage is completed, that is, after the uplink resources are allocated to each uplink logical channel in the first uplink logical channel set in sequence according to the first requirement, if there are remaining resources, the remaining resources are allocated to the RLC status PDUs of each logical channel in sequence from high to low according to the amount to be transmitted and the amount of remaining resources of the remaining RLC status PDUs. Specifically, the remaining resources in the uplink resources are referred to as first uplink resources, and in the second stage, if the remaining first uplink resources exist in the uplink resources, the terminal device sequentially allocates the first uplink resources to the uplink logical channels in the first uplink logical channel set according to the order from high to low of the configuration priority of each uplink logical channel in the first uplink logical channel set.

After the two stages included in the first round of resource allocation are completed, that is, after the uplink resources are allocated to each uplink logical channel in the first uplink logical channel set, if there are remaining resources in the uplink resources, the second round of resource allocation, that is, resource allocation to logical channel data, is continuously performed.

In particular, the second round of resource allocation process may be further divided into two phases, referred to herein as a third phase and a fourth phase. In the third stage, that is, after allocating uplink resources to each uplink logical channel in the first uplink logical channel set, the remaining resources after the first round of resource allocation are referred to as fourth uplink resources, and if there is remaining fourth uplink resources in the uplink resources, the terminal device sequentially allocates the fourth uplink resources to uplink logical channels in which the number of tokens Bj in the second uplink logical channel set is greater than 0 according to a PBR requirement, where the PBR requirement is: the resource allocated to the second uplink logical channel only meets the PBR requirement of the second uplink logical channel, and the second uplink logical channel is any uplink logical channel with the token number Bj greater than 0 in the second uplink logical channel set, that is, the resource is allocated to the uplink logical channel j according to the token number Bj in the PBR token bucket corresponding to the uplink logical channel j in the second uplink logical channel set.

And for the uplink logical channel j allocated to the resource in the third stage, subtracting the size of all MAC SDUs multiplexed to the MAC PDU by the logical channel j in the resource allocation process by the token number Bj of the uplink logical channel j.

After the resource allocation in the third stage is completed, that is, after the fourth uplink resource is allocated to each uplink logical channel in the second uplink logical channel set in which the token number Bj is greater than 0 in sequence according to the PBR requirement, the remaining resources are sequentially allocated to each logical channel in the order from high to low according to the configuration priority of the logical channel regardless of the size of Bj. Specifically, the resource remaining after the fourth uplink resource allocation is referred to as a fifth uplink resource, and if the remaining fifth uplink resource exists in the fourth uplink resource, the terminal device sequentially allocates the fifth uplink resource to the uplink logical channels in the second uplink logical channel set according to the order from high to low of the priority of configuration of each uplink logical channel in the second uplink logical channel set.

The second embodiment described above will be described below by way of example with reference to the accompanying drawings.

Fig. 6 is a schematic diagram illustrating another method for multiplexing uplink logical channels according to an embodiment of the present application. As shown in fig. 6, similar to the embodiment shown in fig. 5, it is still assumed here that the UE establishes 4 uplink logical channels, referred to as LC1, LC2, LC3 and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device, and according to the RRC configuration, the terminal device determines that the order of the configuration priorities of the 4 logical channels is LC1> LC2> LC3> LC4, and meanwhile, the terminal device may also determine the PBR and BSD of each uplink logical channel.

When the UE receives the UL grant indication uplink initial transmission from the network, as shown in fig. 6, the UE completes logical channel multiplexing according to the following steps.

Similar to the embodiment shown in fig. 5, still assuming that the current LCs 2 and LC3 have RLC status reports to be transmitted, the first uplink logical channel set of the current uplink transmission includes LC2 and LC 3; assuming that all of the current LCs 1, the current LCs 2 and the current LCs 4 have data to transmit, the second set of uplink logical channels for uplink transmission includes LCs 1, LCs 2 and LCs 4. And the resource allocation priority of the LC2 and the LC3 in the first uplink logical channel set is higher than that of the LC1, the LC2 and the LC4 in the second uplink logical channel set.

And step 2, executing a first round of resource allocation, and allocating resources for the RLC status reports corresponding to the uplink logical channels, namely the LC2 and the LC3 in the first uplink logical channel set. This step 2 may specifically comprise a step 2.1 and a step 2.2.

And 2.1, sequentially allocating resources for RLC status reports of the LC2 and the LC3 according to the size of the minimum RLC status PDU.

And 2.2, after the resource allocation of the step 2.1 is finished, if the residual resources exist, allocating the resources for the RLC status reports of the LC2 and the LC3 in sequence according to the size requirement of the actual RLC status PDU.

And 3, after the resource allocation of the RLC status report in the step 2 is completed, if the resources remain, continuing to execute the second round of resource allocation, and allocating resources for the uplink logical channel data, namely allocating resources for LC1, LC2 and LC4 in the second uplink logical channel set. This step 3 may specifically comprise a step 3.1 and a step 3.2.

And 3.1, assuming that the token numbers Bj of the LC1, the LC2 and the LC4 are all larger than 0, sequentially allocating resources meeting the PBR for the LC1, the LC2 and the LC4, and updating the token numbers in the PBR token buckets of the LC1, the LC2 and the LC4 according to the resource allocation result.

And 3.2, after the resource allocation of the step 3.1 is finished, if the residual resources exist, allocating the residual resources for LC1, LC2 and LC4 in sequence according to the residual data quantity and the residual resource quantity. As shown in fig. 6, when the resource allocation to LC1 and LC2 is completed, assuming that there are no resources left, the resource allocation to LC4 is not continued; but if, in contrast, the resources are sufficient, the LC4 may continue to be allocated resources.

Optionally, as a third embodiment, similar to the second embodiment, the terminal device may set the resource allocation priority of the RLC status report corresponding to the uplink logical channel to be greater than or equal to the resource allocation priority of the data corresponding to the uplink logical channel; when allocating uplink resources, the terminal device allocates resources to data corresponding to each uplink logical channel after completing resource allocation to RLC status reports corresponding to all uplink logical channels. However, in the third embodiment, the manner of resource allocation of the uplink logical channel corresponding RLC status report by the terminal device is different from that in the second embodiment.

Specifically, the same as the first and second embodiments are: the terminal device determines a first uplink logical channel set and a second uplink logical channel set in the at least one uplink logical channel, and determines that the resource allocation priority of the uplink logical channel in the first uplink logical channel set is higher than the resource allocation priority of the uplink logical channel in the second uplink logical channel set, which is not described herein again for brevity.

The third embodiment is different from the second embodiment in the resource allocation procedure. Specifically, in the third embodiment, the uplink resource allocation process is roughly divided into two rounds, where the first round is resource allocation for a first uplink logical channel set, that is, the terminal device allocates the uplink resource to the uplink logical channel in the first uplink logical channel set according to the configuration priority of each uplink logical channel in the first uplink logical channel set; in the second round, resource allocation is performed on the second uplink logical channel set, that is, after the first round of resource allocation is performed, if there are remaining uplink resources, the terminal device allocates uplink resources to the uplink logical channels in the second uplink logical channel set according to the configuration priority of each uplink logical channel in the second uplink logical channel set.

The third embodiment is different from the first round of resource allocation procedure in the second embodiment in performing the first round of resource allocation, but the second round of resource allocation procedure in the third embodiment is the same as the second round of resource allocation procedure in the second embodiment. Therefore, the first round of resource allocation procedure of the third embodiment will be described below, and for brevity, the second round of resource allocation procedure of the third embodiment will not be described again.

In the first round of resource allocation process, the terminal equipment allocates resources for the RLC status reports of all the logical channels in sequence according to the size requirement of the RLC status PDU according to the sequence from high to low of the configuration priority of all the uplink logical channels in the first uplink logical channel set. Specifically, the terminal device allocates the uplink resource to the uplink logical channels in the first uplink logical channel set in sequence from high to low according to the configuration priority of each uplink logical channel in the first uplink logical channel set and according to the second requirement. When allocating the uplink resource to any uplink logical channel in the first uplink logical channel set, for example, any uplink logical channel in the first uplink logical channel set is referred to as a first uplink logical channel here, and the resource allocated to the first uplink logical channel meets a second requirement, where the second requirement is: the resource allocated for the first uplink logical channel satisfies the size requirement of the RLC status report included in the first uplink logical channel.

That is, only when the RLC status PDUs of the high priority logical channel are all sent and the uplink resources are not exhausted, the resources can be allocated to the RLC status PDUs of the low priority logical channel. I.e. when the terminal device is able to maximize the transmission of RLC status PDUs for the high priority logical channel.

The third embodiment described above will be described below by way of example with reference to the accompanying drawings.

Fig. 7 is a schematic diagram illustrating a further method for uplink logical channel multiplexing according to an embodiment of the present application. As shown in fig. 7, similar to the embodiment shown in fig. 6, it is still assumed here that the UE establishes 4 uplink logical channels, referred to as LC1, LC2, LC3 and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device, and according to the RRC configuration, the terminal device determines that the order of the configuration priorities of the 4 logical channels is LC1> LC2> LC3> LC4, and meanwhile, the terminal device may also determine the PBR and BSD of each uplink logical channel.

When the UE receives the UL grant indication uplink initial transmission from the network, as shown in fig. 7, the UE completes logical channel multiplexing according to the following steps.

Similar to the embodiment shown in fig. 6, still assuming that the current LCs 2 and LC3 have RLC status reports to be transmitted, the first uplink logical channel set of the current uplink transmission includes LC2 and LC 3; assuming that all of the current LCs 1, the current LCs 2 and the current LCs 4 have data to transmit, the second set of uplink logical channels for uplink transmission includes LCs 1, LCs 2 and LCs 4. And the resource allocation priority of the LC2 and the LC3 in the first uplink logical channel set is higher than that of the LC1, the LC2 and the LC4 in the second uplink logical channel set.

And step 2, executing a first round of resource allocation, and allocating resources for the RLC status reports corresponding to the uplink logical channels, namely the LC2 and the LC3 in the first uplink logical channel set. Specifically, resources are allocated for RLC status reports of LC2 and LC3 in order of the configured priorities of LC2 and LC3 according to actual RLC status PDU size requirements.

And 3.2, after the resource allocation of the step 3.1 is finished, if the residual resources exist, allocating the residual resources for LC1, LC2 and LC4 in sequence according to the residual data quantity and the residual resource quantity. As shown in fig. 7, when the resource allocation to LC1 and LC2 is completed, assuming that there are no resources left, the resource allocation to LC4 is not continued; but if, in contrast, the resources are sufficient, the LC4 may continue to be allocated resources.

Optionally, as a fourth embodiment, the terminal device may set the resource allocation priority of the uplink logical channel to which the RLC status report is to be transmitted to be greater than or equal to the resource allocation priority of the uplink logical channel to which no RLC status report is to be transmitted. In addition, when allocating uplink resources, the allocation is performed in approximately two rounds, and for each round of resource allocation, resources are sequentially allocated according to the resource allocation priority of the logical channel. And allocating resources meeting the PBR in the first round, and allocating resources according to the residual data volume to be transmitted in the second round.

Specifically, unlike the previous three embodiments, in this fourth embodiment, S210 in the method 200 may specifically include: the terminal equipment determines a first uplink logical channel set and a third uplink logical channel set in at least one uplink logical channel according to the bearing type of the at least one uplink logical channel, wherein the bearing of each uplink logical channel in the first uplink logical channel set comprises an RLC status report, and the bearing of each uplink logical channel in the third uplink logical channel set does not comprise the RLC status report; the terminal equipment determines that the resource allocation priority of the uplink logical channel in the first uplink logical channel set is higher than the resource allocation priority of the uplink logical channel in the third uplink logical channel set.

That is, the terminal device divides the logical channels into two sets, where the concept of the first uplink logical channel set is consistent with that of the first uplink logical channel set in the foregoing three embodiments, and for any uplink logical channel in at least one uplink logical channel, if the uplink logical channel corresponds to an RLC status report to be transmitted, the uplink logical channel belongs to the first uplink logical channel set; if the uplink logical channel has no RLC status report to be transmitted but has data to be transmitted, for example, the uplink logical channel is only used for carrying data, then the uplink logical channel belongs to the third uplink logical channel set. That is, each uplink logical channel belongs to at most one uplink logical channel set. If a certain uplink logical channel has a RLC status report to be transmitted and data to be transmitted at the same time, the uplink logical channel belongs to the first uplink logical channel set but does not belong to the second uplink logical channel set.

In addition, the terminal equipment determines that the resource allocation priority of the uplink logical channel in the first uplink logical channel set is higher than or equal to the resource allocation priority of the uplink logical channel in the third uplink logical channel set; for the uplink logical channels in the same uplink logical channel set, the configuration priority may be determined as a resource allocation priority, that is, the terminal device determines the configuration priority of each uplink logical channel in the first uplink logical channel set as a resource allocation priority; and the terminal equipment determines the configuration priority of each uplink logical channel in the third uplink logical channel set as the resource allocation priority.

The terminal device may allocate uplink resources to at least one uplink logical channel according to the order of the resource allocation priorities of each uplink logical channel. Specifically, the uplink resource allocation procedure can be roughly divided into two rounds. First, a first round of resource allocation process is introduced, and the terminal device allocates resources satisfying the PBR for the uplink logical channel. And for all uplink logical channels with the Bj >0 in the first uplink logical channel set and the third uplink logical channel, allocating resources according to the sequence from high to low of the resource allocation priority, wherein the resources allocated to each uplink logical channel can only meet the requirement of the PBR, namely allocating the resources for the logical channel according to the token number Bj in the PBR token bucket corresponding to the logical channel j.

Specifically, the terminal device allocates the uplink resources to the uplink logical channels with the token number Bj greater than 0 in the first uplink logical channel set and the third uplink logical channel set in sequence from high to low according to the resource allocation priority of each uplink logical channel in the first uplink logical channel set and the third uplink logical channel set and according to the PBR requirement, where the PBR requirement is: and the resource allocated to the third uplink logical channel meets the PBR requirement of the third uplink logical channel, and the third uplink logical channel is any one of the first uplink logical channel set and the third uplink logical channel set, wherein the token number Bj is greater than 0.

And for the uplink logical channel j allocated to the resources in the first round of resource allocation process, subtracting the size of all MAC SDUs multiplexed to the MAC PDU by the logical channel j from the token number Bj of the uplink logical channel j.

After the first round of resource allocation is completed, that is, after the uplink resources are allocated to each uplink logical channel with the token number Bj greater than 0 in the first uplink logical channel set and the third uplink logical channel set in sequence according to the PBR requirement, if there are remaining uplink resources, the remaining resources are allocated to each logical channel in sequence according to the resource allocation priority of the logical channel from high to low regardless of the size of Bj.

Specifically, the resource remaining after the first round of resource allocation is executed is referred to as a sixth uplink resource, and if the remaining sixth uplink resource exists in the uplink resources, the terminal device sequentially allocates the sixth uplink resource to the uplink logical channels in the first uplink logical channel set and the third uplink logical channel set according to the order from high to low of the resource allocation priority of each uplink logical channel in the first uplink logical channel set and the third uplink logical channel set.

The fourth embodiment described above will be described below by way of example with reference to the accompanying drawings.

Fig. 8 is a schematic diagram illustrating a further method for uplink logical channel multiplexing according to an embodiment of the present application. As shown in fig. 8, it is assumed here that the UE establishes 4 uplink logical channels, referred to as LC1, LC2, LC3, and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device, and according to the RRC configuration, the terminal device determines that the order of the configuration priorities of the 4 logical channels is LC1> LC2> LC3> LC4, and meanwhile, the terminal device may also determine the PBR and BSD of each uplink logical channel.

When the UE receives the UL grant indication uplink initial transmission from the network, as shown in fig. 8, the UE completes logical channel multiplexing according to the following steps.

Step 1, determining candidate logical channels and resource allocation priorities of the current uplink transmission.

Assuming that the RLC status reports to be transmitted by the current LCs 2 and the current LCs 3, the current LCs 1, the current LCs 2 and the current LCs 4 have uplink data to be transmitted, that is, the RLC status reports to be transmitted by the LCs 2 and the LC3, and the current LCs 1 and the current LCs 4 do not have the RLC status reports to be transmitted, it is determined that the first uplink logical channel set of the current uplink transmission includes the LCs 2 and the LCs 3, and the third uplink logical channel set includes the LCs 1 and the LCs 4. The resource allocation priority of the LC2 and the LC3 in the first uplink logical channel set is higher than that of the LC1 and the LC4 in the third uplink logical channel set. Therefore, the resource allocation priorities of the four uplink logical channels are LC2> LC3> LC1> LC 4.

And 2, executing the first round of resource allocation according to the sequence of the resource allocation priorities of the four uplink logical channels from high to low. Specifically, assuming that the token numbers Bj of the four logical channels are all greater than 0, resources meeting the PBR are allocated to the LC2, the LC3, the LC1 and the LC4 in sequence, and the token numbers in the PBR token buckets of the four logical channels are updated according to the resource allocation result.

And 3, after the first round of resource allocation is finished, if the residual resources exist, continuing to execute the second round of resource allocation, namely allocating the residual resources to the LC2, the LC3, the LC1 and the LC4 in sequence according to the residual data amount and the residual resource amount.

Optionally, under the condition that the first uplink logical channel set and the third uplink logical channel set are determined according to the fourth embodiment, in addition to allocating uplink resources according to the manner described in the fourth embodiment, resource allocation may also be performed in other manners according to a principle that the resource allocation priority of an uplink logical channel in the first uplink logical channel set is higher than that of an uplink logical channel in the third uplink logical channel set, which is not limited to this embodiment of the present application.

For example, in the first round of resource allocation process, only the uplink logical channels in the first uplink logical channel set may be allocated with uplink resources, and the second round of resource allocation process is the same as the fourth embodiment. Specifically, fig. 9 shows a schematic diagram of another method for uplink logical channel multiplexing according to an embodiment of the present application. As shown in fig. 9, similar to fig. 8, it is still assumed here that the UE establishes 4 uplink logical channels, referred to as LC1, LC2, LC3 and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device, and according to the RRC configuration, the terminal device determines that the order of the configuration priorities of the 4 logical channels is LC1> LC2> LC3> LC4, and meanwhile, the terminal device may also determine the PBR and BSD of each uplink logical channel.

When the UE receives the UL grant indication uplink initial transmission from the network, as shown in fig. 9, the UE completes logical channel multiplexing according to the following steps.

Assuming that the RLC status reports to be transmitted by the current LCs 2 and the current LCs 3, the current LCs 1, the current LCs 2 and the current LCs 4 have uplink data to be transmitted, that is, the RLC status reports to be transmitted by the LCs 2 and the LC3, and the current LCs 1 and the current LCs 4 do not have the RLC status reports to be transmitted, it is determined that the first uplink logical channel set of the current uplink transmission includes the LCs 2 and the LCs 3, and the third uplink logical channel set includes the LCs 1 and the LCs 4. The resource allocation priority of the LC2 and the LC3 in the first uplink logical channel set is higher than that of the LC1 and the LC4 in the third uplink logical channel set.

And 2, executing a first round of resource allocation according to the sequence from high to low of the configuration priority of the uplink logical channels in the first uplink logical channel set. Specifically, assuming that the token numbers Bj of the LC2 and the LC3 are both greater than 0, resources satisfying the PBR are allocated to the LC2 and the LC3 in turn, and the token numbers in the PBR token buckets of the two logical channels are updated according to the resource allocation result.

It should be understood that the size of the smallest PDU of the RLC status report in various embodiments of the present application may be a predefined value, for example, may be a fixed value specified by a standard; alternatively, the size of the minimum PDU of the RLC status report may be sent from the RLC layer to the MAC layer by the terminal device, that is, the RLC entity informs the MAC entity, and may be implemented by an RLC and MAC layer interface, for example.

Therefore, according to the method for allocating resources to an uplink logical channel in the embodiment of the present application, the terminal device preferentially allocates resources to the RLC status report in the process of completing uplink logical channel multiplexing according to uplink transmission resources allocated by the network device according to different logical channel bearing types, so that scheduling delay of the RLC status report can be reduced, and RLC express retransmission is achieved.

It should be understood that, in the various embodiments of the present application, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
