At present, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) is studying NTN technology. NTN generally uses satellite communications to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user area. For example, general terrestrial communication cannot cover the ocean, mountains, deserts and other areas where communication equipment cannot be installed or because of the sparse population. Satellites can cover a larger ground, and satellites can orbit the earth, so in theory every corner of the earth can be covered by satellite communications. Secondly, satellite communication has greater social value. Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed areas and promoting The development of these areas. Third, the satellite communication distance is long, and the communication cost has not increased significantly with the increase of the communication distance; finally, the satellite communication has high stability and is not restricted by natural disasters.

According to different orbital heights, communication satellites can generally be divided into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, etc. The main research at this stage is LEO and GEO.

The altitude range of LEO satellites is 500km-1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite viewing time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirement for the transmission power of the user terminal is not high.

The GEO satellite has an orbital height of 35786km and a rotation period of 24 hours around the earth. The signal propagation delay of single-hop communication between users is generally 250ms.

In order to ensure the coverage of satellites and increase the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. Ground area.

The NR HARQ mechanism is introduced below.

NR is provided with two levels of retransmission mechanisms: the HARQ mechanism of the Media Access Control (MAC) layer and the ARQ mechanism of the RLC layer. The retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and 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 Stop-and-Wait Protocol to send data. In the stop-and-wait protocol, after the sender sends a Transport Block (TB), it stops and waits for the confirmation message. In this way, the sender will stop and wait for confirmation after each transmission, which will result in very low user throughput. Therefore, NR uses multiple parallel HARQ processes. When one HARQ process is waiting for confirmation information, the sender can use another HARQ process to continue sending data. These HARQ processes together form a HARQ entity, which combines the stop-and-wait protocol to allow continuous data transmission. HARQ is divided into 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 NR protocol, the terminal has its own HARQ entity corresponding to 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 can indicate the maximum number of HARQ processes to the UE through radio resource control (Radio Resource Control, RRC) signaling semi-static configuration according to the network deployment situation. If the network does not provide corresponding configuration parameters, the default number of HARQ processes in the downlink is 8, and the maximum number of HARQ processes supported by each carrier in the uplink is always 16. Each HARQ process corresponds to a HARQ process identifier (Identity, ID). For the downlink, the Broadcast Control Channel (BCCH) uses a dedicated broadcast HARQ process. For the uplink, HARQ ID 0 is used for Msg3 transmission in the random process.

For terminals that do not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB at the same time; for terminals that support downlink space division multiplexing, each downlink HARQ process can process 1 or 2 TBs at the same time. Each uplink HARQ process of the terminal processes 1 TB at the same time.

HARQ is divided into two types, synchronous and asynchronous in the time domain, and divided into two types, non-adaptive and adaptive in the frequency domain. Both NR uplink and downlink use asynchronous adaptive HARQ mechanism. Asynchronous HARQ, that is, retransmission can occur at any time, and the time interval between the retransmission of the same TB and the previous transmission is not fixed. Adaptive HARQ can change the frequency domain resources and modulation and coding strategy (Modulation and Coding Scheme, MCS) used for retransmission.

The NR ARQ mechanism is introduced below.

Each logical channel of the UE has an RLC entity. An RLC entity can be configured as one of three modes: Transparent Mode (TM), Unacknowledged Mode (UM) and Acknowledged Mode (AM). Among them, only the AM mode can support error detection and ARQ retransmission.

On the gNB side or the UE side, an AM entity includes both a receiving side and a transmitting side, that is, it can send and receive data at the same time. AM entities provide two-way data transmission services.

The AM entity sends/receives two types of protocol data units (Protocol Data Unit, PDU), namely RLC data PDU and RLC control PDU. Among them, the RLC data PDU is used to transmit data, and the RLC control PDU is used to transmit status reports.

For AM RLC entities, by detecting the sequence number (Sequence Number, SN) of the received RLC data PDU, the receiving end can know which PDUs (or segments thereof) have been lost, and request the sending end to retransmit the lost PDU (or its segment). Subsection). The receiving end will tell the sending end which AMD PDUs have been successfully received and which AMD PDUs or segments have not been successfully received through the sending status report. After receiving the status report, the sender will initiate an ARQ retransmission.

Specifically, there are two scenarios that trigger the status report: Scenario 1: The sender initiates polling; Scenario 2: The reassembly timer (t-Reassembly) expires, which means there is confirmation mode data (AM Data, AMD). ) PDU was 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 (Service Data Unit, SDU) is lost, and t-Reassembly is not currently running, t-Reassembly is started.

Figures 2 and 3 show RLC control PDUs in two different formats. RLC control PDU (or RLC status PDU) includes a status report PDU payload and an RLC status PDU header, as shown in Figure 2 and Figure 3, each row represents an 8-bit group (Octet, Oct) . The RLC status PDU header consists of a Data/Control (D/C) indication field and a Control PDU Type (Control PDU Type, CPT) indication field. The D/C field is used to indicate that the PDU is a data PDU. It is also the control PDU; the CPT field is used to indicate the type of RLC PDU.

The status PDU payload can include: one "Acknowledge (ACK)_SN+E1", zero or more "Non-Acknowledge (NACK)_SN+E1+E2+E3" combinations and possible SOstart( Start) and SOend (end) or NACK range (range) fields. Among them, "ACK_SN" corresponds to the SN value of the next RLC data PDU that has not been reported as lost in the status PDU. When the sender receives a status PDU, except for those AMD PDUs indicated by NACK_SN and AMD PDU segments indicated by NACK_SN+E1+E2+E3, the sender thinks that AMD PDUs with SN<ACK_SN have been successfully received by the peer .

It should be understood that the ACK_SN is set to the SN of the next RLC data PDU that has not been received and is not indicated as lost in the status PDU. 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 enough to accommodate the NACK information of all RLC data PDUs that are lost within the receiving window, ACK_SN will be set to a value smaller than or equal to the upper boundary of the receiving window.

"NACK_SN" corresponds to the SN value of those AMD PDUs or AMD PDU segments deemed lost by the receiving end. NACK_SN may correspond to a missing AMD PDU, or it may correspond to a missing AMD PDU segment. If one AMD PDU is lost, there will be a corresponding "NACK_SN+E1+E2+E3" combination in the status PDU; if the missing is an AMD PDU segment, there will be a corresponding "NACK_SN+" in the status PDU E1+E2+E3+SOstart+SOend" combination. "SOstart" and "SOend" together indicate which part of the AMD PDU with SN=NACK_SN is missing. Among them, "SOstart" corresponds to the position of the first byte of the missing segment in the Data field of the original AMD PDU, and "SOend" corresponds to the position of the last byte of the missing segment in the Data field of the original AMD PDU.

The following introduces NR logical channel priority (Logical Channel Prioritization, LCP) processing.

Same as LTE, in NR, the network allocates uplink transmission resources based on each user (per-UE) instead of each bearer (per-bearer). Which radio bearer data can be put into the allocated uplink transmission resources for transmission It is determined by the UE.

Based on the uplink transmission resources configured by the network, the UE needs to determine the amount of transmission data for each logical channel in the initial transmission MAC protocol data unit (PDU). In some cases, the UE also needs to allocate resources for the MAC CE. In order to realize the multiplexing of uplink logical channels, each uplink logical channel needs to be assigned a priority. For a MAC PDU of a given size, when there are multiple uplink logical channels that have data transmission requirements at the same time, the resources of the MAC PDU are allocated in order according to the logical channel priority corresponding to each uplink logical channel in descending order. At the same time, in order to take into account the fairness between different logical channels, the probability of Prioritized Bit Rate (PBR) is introduced. When the UE performs logical channel multiplexing, it is necessary to ensure the minimum data rate requirements of each logical channel. Avoid the situation that other uplink logical channels with low priority of the UE are "starved" because the uplink logical channel with high priority always occupies the uplink resources allocated to the UE by the network.

In order to realize the multiplexing of uplink logical channels, the network usually configures the following parameters for each uplink logical channel through RRC: Logical channel priority (priority): the smaller the priority value, the higher the corresponding priority; PBR means The minimum rate that the logical channel needs to guarantee; Bucket Size Duration (BSD): This parameter determines the depth of the token bucket.

The MAC of the UE uses the token bucket mechanism to implement uplink logical channel multiplexing. Specifically, the UE maintains a variable Bj for each uplink logical channel j, which indicates the number of tokens currently available in the token bucket. The method is as follows: When the UE establishes logical channel j, initialize Bj to 0; Before the next LCP process, increase Bj by PBR*T, where T is the time interval from the time when Bj was last increased to the current time; if Bj updated according to step 2 is greater than the maximum capacity of the token bucket (ie PBR*BSD), then Set Bj to the maximum capacity of the token bucket.

When the UE receives an uplink (UL) grant indicating a new transmission, the UE performs LCP processing according to the following steps.

Step 1: For all logical channels with Bj>0, resources are allocated in order of priority from high to low. The resources allocated for each logical channel can only meet the requirements of PBR, that is, according to the PBR token bucket corresponding to the logical channel The number of tokens allocates resources for this logical channel. When the PBR of a certain logical channel is set to infinity, only when the resources of this logical channel are satisfied, will other logical channels with lower priority than it be considered.

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

Step 3: If there are remaining uplink resources after performing

steps

1 and 2, regardless of the size of the Bj of each logical channel (that is, whether greater than 0, equal to 0, or less than 0), follow the priority of the logical channel from high to low The remaining resources are allocated to each logical channel in sequence. Only when the data of the high-priority logical channels are all sent, and the UL grant has not been exhausted, the low-priority logical channels can be served. That is, at this time, the UE maximizes the data transmission of the high-priority logical channel.

At the same time, the UE should also follow the following principles: if the entire RLC SDU can be filled in the remaining resources, the RLC SDU should not be segmented; if the UE segment the RLC SDU in the logical channel, it should be based on The size of the remaining resources should be filled in the largest segment as much as possible; the UE should maximize the data transmission; if the UL grant size is greater than or equal to 8 bytes, and the UE has data transmission requirements, the UE cannot only send a padding buffer status report (Buffer Status Report, BSR) or send only padding.

For different signals and/or logical channels, when the UE performs LCP processing, it also needs to follow the following priority order (arranged in descending order of priority): Cell-Radio Network Temporary Identifier (Cell-Radio Network Temporary Identifier, C) -RNTI) MAC control element (Control Element, CE) or data from UL common control channel (common control channel, CCCH); Configured Grant Confirmation MAC CE; used for BSR MAC CE except padding BSR ; Single Entry (Single Entry) Power Headroom Report (PHR) MAC CE or Multiple Entry (Multiple Entry) PHR MAC CE; data from any logical channel except UL-CCCH; used to recommend bit rate Query (Recommended bit rate query) MAC CE; BSR MAC CE used for padding BSR.

In view of the large transmission delay of the wireless signal between the terminal and the satellite in the NTN system, the introduction of the disabling HARQ function to reduce the data transmission delay is being discussed during the 3GPP standardization process for the NTN, and the HARQ function is being disabled. Next, RLC ARQ retransmission can be used to ensure transmission reliability. Therefore, it is necessary to study how to reduce the delay of RLC retransmission.

RLC retransmission is triggered by the RLC status report, and the RLC status report is transmitted on the PUSCH or PDSCH.

For uplink transmission, since the network allocates PUSCH resources based on the UE, the UE determines which logical channels are transmitted on the resources allocated by the network. Based on current standards, the UE performs logical channel multiplexing based on the logical channel priority of the network configuration. The main consideration for the priority configuration of the logical channel is the service (Quality of Service, QoS) requirement. For each logical channel, whether RLC status PDU or RLC data PDU needs to be transmitted, there is no distinction in the process of logical channel multiplexing. How to realize the rapid transmission of RLC status PDU requires a set of rules from the standard level.

Therefore, the embodiment of the present application proposes a method for allocating resources for uplink logical channels, which can solve the above-mentioned problems.

FIG. 4 is a schematic flowchart of a method 200 for allocating resources for uplink logical channels according to an embodiment of the application. The method 200 may be executed by a terminal device. For example, the terminal device may be a terminal device as shown in FIG. 1. As shown in FIG. 2, the method 200 includes: S210. The terminal device determines the resource allocation priority of the at least one uplink logical channel according to the bearer type of the at least one uplink logical channel. The bearer type indicates that the bearer of the uplink logical channel includes RLC. Status report and/or data.

Optionally, the method 200 may further include: the terminal device determines the bearer type of the at least one uplink logical channel. Specifically, the AM entity can send/receive two types of PDUs, namely RLC data PDUs and RLC control PDUs, where RLC data PDUs are used to transmit data, and RLC control PDUs are used to transmit status reports. Correspondingly, for any uplink logical channel, the uplink logical channel can be used to carry RLC status reports; or, the uplink logical channel can also be used to carry data; or, the uplink logical channels can also be used to carry RLC status reports, and data. Therefore, the terminal device determines the bearer type of each logical channel, that is, determines that each logical channel is used to carry the RLC status report and/or data.

In this S210, the terminal device can determine the resource allocation priority of each logical channel according to the bearer type of each logical channel, and the resource allocation priority is used to indicate the sequence of resource allocation for each logical channel.

As shown in FIG. 2, the method 200 further includes: S220. The terminal device allocates uplink resources for 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 the resource allocation priority of different logical channels according to different bearer types of different logical channels; and according to the different resource allocation priority, allocates uplink resources to different logical channels in order. The uplink resource may be any uplink resource, for example, it may be a UL grant indicated by the network device received by the terminal device, or may also be other uplink resources. A detailed description will be given below in conjunction with several different situations.

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 , Roughly divided into two rounds, for each round of resource allocation, first allocate resources for each uplink logical channel corresponding to the RLC status report, and then allocate resources for each uplink logical channel corresponding to the data.

Specifically, S210 in the embodiment of the present application may include: the terminal device determines the first uplink logical channel set and the second uplink logical channel set in the at least one uplink logical channel according to the bearer type of the at least one uplink logical channel, where , The bearer of each uplink logical channel in the first uplink logical channel set includes an RLC status report, and the bearer of each uplink logical channel in the second uplink logical channel set includes data; the terminal device determines the first uplink logical channel set The resource allocation priority of the uplink logical channel in 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. For any one of the at least one uplink logical channel, if the uplink logical channel corresponds to the RLC status report to be transmitted, then the uplink logical channel belongs to the first one. The uplink logical channel set; if the uplink logical channel corresponds to the data to be transmitted, then the uplink logical channel belongs to the 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, then the uplink logical channel The channel is both the first uplink logical channel set and the second uplink logical channel set. That is, the at least one uplink logical channel may include uplink logical channels that belong to the first uplink logical channel set and the second uplink logical channel set at the same time.

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, then the terminal device can allocate the priority according to the resource Allocate uplink resources for at least one uplink logical channel.

Specifically, the uplink resource allocation process can be roughly divided into two rounds, and each round can be further divided into two stages. First introduce the first round of resource allocation process, the process can further include the first phase and the second phase. For the first stage, the terminal equipment allocates the uplink logical channels in the first uplink logical channel set in the order of the configuration priority of each uplink logical channel in the first uplink logical channel set from high to low. Uplink resource, where, when the uplink resource is allocated to any uplink logical channel in the first uplink logical channel set, for example, here any uplink logical channel in the first uplink logical channel set is referred to as the first uplink Logical channel, the resource allocated for the first uplink logical channel meets the first requirement, and the first requirement is: the resource allocated for the first uplink logical channel meets the minimum PDU of the RLC status report included in the first uplink logical channel The size requirements.

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 it. For example, the smaller the priority value, the higher the priority of the corresponding logical channel. In order to distinguish it from the resource allocation priority, the priority configured by the network device is referred to herein as the configuration priority of the logical channel.

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

For the second phase, after the resource allocation of the first phase 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 is still remaining Resources, the first round of resource allocation for logical channel data is continued, that is, for all uplink logical channels with Bj>0 in the second uplink logical channel set, resources are allocated in the order of priority from high to low, and each uplink logical channel The resources allocated by the channel can only meet the requirements of the PBR.

Specifically, here, the remaining resources existing in the uplink resources are referred to as the first uplink resources. Then, in the second stage, the terminal equipment according to the configuration priority of each uplink logical channel in the second uplink logical channel set is higher. In the lower order, and according to the PBR requirement, the first uplink resource is allocated to the uplink logical channels in the second uplink logical channel set whose token number Bj is greater than 0. Wherein, the PBR requirement is: the resource allocated for the second uplink logical channel meets the PBR requirement of the second uplink logical channel, and the second uplink logical channel is any number of tokens Bj in the second uplink logical channel set that is greater than 0 An upstream logical channel.

For the second stage in the first round of resource allocation, the uplink logical channel j allocated to the resource is subtracted from the number of tokens Bj and the logical channel j is multiplexed into the MAC PDU in the first round of resource allocation. The size of all MAC SDUs.

After completing the two stages of the first round of resource allocation, that is, in accordance with the PBR requirements, sequentially allocate the first uplink resource to each uplink logical channel in the second uplink logical channel set whose token number Bj is greater than 0 After that, if there are still remaining resources, the second round of resource allocation process is continued, and the second round of resource allocation process may further include the third stage and the fourth stage. For the third stage, the second round of resource allocation for the RLC status report will continue. Specifically, the resources remaining after the above-mentioned allocation of the first uplink resource are referred to as the second uplink resource, and the terminal equipment follows the order of the configuration priority of each uplink logical channel in the first uplink logical channel set from high to low. To sequentially allocate the second uplink resource to the uplink logical channels in the first uplink logical channel set. Only when the RLC status PDUs of the uplink logical channel with high configuration priority are all sent, and the uplink resources are not exhausted, resources can be allocated for the RLC status PDU of the uplink logical channel with low configuration priority. That is, the terminal device will maximize the transmission of the RLC status PDU of the uplink logical channel with the high configuration priority at this time.

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 turn, if there are still remaining uplink resources, regardless of the size of Bj, The remaining resources are allocated to each uplink logical channel in the order of the configuration priority of the uplink logical channel from high to low. Specifically, the resources remaining after the above-mentioned allocation of the second uplink resource are referred to as the third uplink resource. Then, if there is a third uplink resource remaining in the second uplink resource, the terminal device is in accordance with the second uplink logical channel set. The configuration priority of each uplink logical channel is in descending order, and the third uplink resource is allocated to the uplink logical channels in the second uplink logical channel set in turn.

Hereinafter, the above-mentioned first embodiment will be described as an example with reference to the accompanying drawings.

Fig. 5 shows a schematic diagram of an uplink logical channel multiplexing method according to an embodiment of the present application. As shown in FIG. 5, it is assumed that the UE has established 4 uplink logical channels (Logical Channel, LC), which are called LC1, LC2, LC3, and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device. According to the RRC configuration, the terminal device determines the configuration priority of the 4 logical channels in the order of LC1>LC2>LC3>LC4. At the same time, the terminal device can also determine each uplink logic PBR and BSD of the channel.

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

Step 1. Determine the candidate logical channel for this uplink transmission.

Assuming that the current LC2 and LC3 have RLC status reports to be transmitted, the first uplink logical channel set of this uplink transmission includes LC2 and LC3; assuming that the current LC1, LC2, and LC4 all have data to be transmitted, the second uplink transmission is the second The uplink logical channel set includes LC1, LC2, and LC4. Wherein, the resource allocation priority of LC2 and LC3 in the first uplink logical channel set is higher than the resource allocation priority of LC1, LC2 and LC4 in the second uplink logical channel set.

Step 2: Perform the first round of resource allocation according to the resource allocation priority and configuration priority of the four uplink logical channels. This step 2 may specifically include step 2.1 and step 2.2.

Step 2.1: First, allocate resources for the RLC status reports of LC2 and LC3 according to the size of the smallest RLC status PDU.

Step 2.2. After completing step 2.1, if there are remaining resources, and assuming that the number of tokens Bj of LC1, LC2, and LC4 is greater than 0, then allocate resources that meet PBR to LC1, LC2, and LC4 in turn, and according to the resource allocation result Update the number of tokens in the PBR token buckets of LC1, LC2, and LC4.

Step 3: After completing the first round of resource allocation, if there are remaining resources, continue to perform the second round of resource allocation. This step 3 may specifically include step 3.1 and step 3.2.

In step 3.1, resources are allocated for the RLC status reports of LC2 and LC3 according to the actual RLC status PDU size requirements.

Step 3.2: After completing step 3.1, if there are remaining resources, the remaining resources are allocated to LC1, LC2, and LC4 in sequence according to the amount of remaining data and the amount of remaining resources. As shown in FIG. 5, after the resource allocation for LC1 and LC2 is completed, assuming that there are no remaining resources, no more resources are allocated for LC4; but on the contrary, if resources are sufficient, resources can be allocated for LC4.

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 will allocate resources for data corresponding to each uplink logical channel after completing the resource allocation for the RLC status report corresponding to all uplink logical channels.

Specifically, the same as the first embodiment is that the terminal device determines the first uplink logical channel set and the second uplink logical channel set in the at least one uplink logical channel, and determines the uplink in the first uplink logical channel set. The resource allocation priority of the logical channel is higher than the resource allocation priority of the uplink logical channel in the second uplink logical channel set. For the sake of brevity, details are not described herein again.

The second embodiment is different from the first embodiment in the resource allocation process. Specifically, in the second embodiment, the uplink resource allocation process is roughly divided into two rounds. The first round is to allocate resources to the first set of uplink logical channels, that is, the terminal device allocates resources according to the first set of uplink logical channels. In the configuration priority of each uplink logical channel in the first uplink logical channel set, the uplink resource is allocated to the uplink logical channel in the first uplink logical channel set; the second round is the resource allocation for the second uplink logical channel set, that is, the first round is executed After resource allocation, if there are remaining uplink resources, the terminal device allocates uplink resources for 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 introduce the first round of resource allocation process, the process can further include the first phase and the second phase. For the first stage, according to the order of configuration priority of each uplink logical channel in the first uplink logical channel set, resources are allocated for the RLC status report of each uplink logical channel according to the size of the smallest RLC status PDU. 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 is not repeated here for brevity.

For the second phase, after the resource allocation of the first phase 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 is still remaining Resources, according to the remaining RLC status PDUs to be transmitted and the remaining resources, the remaining resources are allocated to the RLC status PDUs of each logical channel in the order of the logical channel configuration priority from high to low. Specifically, here, the remaining resources existing in the uplink resources are referred to as the first uplink resources. Then, in the second stage, if there are remaining first uplink resources in the uplink resources, the terminal device sets according to the first uplink logical channel. The configuration priority of each uplink logical channel in is in descending order, and the first uplink resource is allocated to the uplink logical channels in the first uplink logical channel set in turn.

After completing the two phases included in the first round of resource allocation, that is, after allocating uplink resources for each uplink logical channel in the first uplink logical channel set, if there are remaining resources in the uplink resources, continue to perform the second Round resource allocation, that is, resource allocation for logical channel data.

Specifically, the second round of resource allocation process can also be further divided into two stages, which are referred to herein as the third stage and the fourth stage. Among them, in the third stage, that is, after allocating uplink resources for each uplink logical channel in the first uplink logical channel set, the resources remaining after the first round of resource allocation are referred to here as the fourth uplink resource. There is a remaining fourth uplink resource in the uplink resources, and the terminal equipment is in the order of the configuration priority of each uplink logical channel in the second uplink logical channel set from high to low, and according to the PBR requirement, the second uplink The fourth uplink resource is allocated to the uplink logical channel with the number of tokens Bj greater than 0 in the logical channel set. The PBR requirement is: the resource allocated for the second uplink logical channel only meets the PBR requirement of the second uplink logical channel. The second uplink logical channel is any uplink logical channel in the second uplink logical channel set whose number of tokens Bj is greater than 0, that is, according to the tokens in the PBR token bucket corresponding to the uplink logical channel j in the second uplink logical channel set The number Bj allocates resources for the uplink logical channel j.

For the uplink logical channel j allocated to the resource in the third stage, the number of tokens Bj is subtracted from the size of all the MAC SDUs of the logical channel j that are multiplexed into the MAC PDU in this resource allocation process.

After completing the resource allocation in the third phase, that is, after the fourth uplink resource is allocated to each uplink logical channel in the second uplink logical channel set with the number of tokens Bj greater than 0 in sequence according to the PBR requirements, regardless of the size of Bj , The remaining resources are allocated to each logical channel in the order of the configuration priority of the logical channel from high to low. Specifically, the resources remaining after the above allocation of the fourth uplink resource is referred to as the fifth uplink resource. If there is a fifth uplink resource remaining in the fourth uplink resource, the terminal device is in accordance with the set of the second uplink logical channel. The configuration priority of each uplink logical channel is in descending order, and the fifth uplink resource is allocated to the uplink logical channels in the second uplink logical channel set in turn.

Hereinafter, the above-mentioned second embodiment will be described as an example with reference to the accompanying drawings.

FIG. 6 shows a schematic diagram of 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 that the UE has established 4 uplink logical channels, which are called LC1, LC2, LC3, and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device. According to the RRC configuration, the terminal device determines the configuration priority of the 4 logical channels in the order of LC1>LC2>LC3>LC4. At the same time, the terminal device can also determine each uplink logic PBR and BSD of the channel.

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

Step 1. Determine the candidate logical channel for this uplink transmission.

Similar to the embodiment shown in Figure 5, still assuming that the current LC2 and LC3 have RLC status reports to be transmitted, the first uplink logical channel set of this uplink transmission includes LC2 and LC3; assuming that the current LC1, LC2 and LC4 are all waiting To transmit data, the second uplink logical channel set for this uplink transmission includes LC1, LC2, and LC4. Wherein, the resource allocation priority of LC2 and LC3 in the first uplink logical channel set is higher than the resource allocation priority of LC1, LC2 and LC4 in the second uplink logical channel set.

Step 2: Perform the first round of resource allocation to allocate resources for the uplink logical channel corresponding to the RLC status report, that is, LC2 and LC3 in the first uplink logical channel set. This step 2 may specifically include step 2.1 and step 2.2.

Step 2.1: Assign resources to the RLC status reports of LC2 and LC3 in sequence according to the size of the smallest RLC status PDU.

Step 2.2: After completing the resource allocation of step 2.1, if there are remaining resources, then the RLC status reports of LC2 and LC3 are allocated in accordance with the actual RLC status PDU size requirements.

Step 3. After completing the resource allocation for the RLC status report in Step 2, if there are remaining resources, continue to perform the second round of resource allocation to allocate resources for uplink logical channel data, that is, LC1 in the second uplink logical channel set , LC2 and LC4 allocate resources. This step 3 may specifically include step 3.1 and step 3.2.

Step 3.1, assuming that the number of tokens Bj of LC1, LC2, and LC4 is greater than 0, allocate resources that meet PBR to LC1, LC2, and LC4 in turn, and update the commands in the PBR token buckets of LC1, LC2, and LC4 according to the resource allocation results Number of cards.

Step 3.2: After the resource allocation of step 3.1 is completed, if there are remaining resources, the remaining resources are allocated to LC1, LC2, and LC4 in sequence according to the amount of remaining data and the amount of remaining resources. As shown in Figure 6, after the resource allocation for LC1 and LC2 is completed, assuming that there are no remaining resources, no more resources are allocated for LC4; but if the opposite is true, if resources are sufficient, resources can be allocated for LC4.

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 will allocate resources for data corresponding to each uplink logical channel after completing the resource allocation for the RLC status report corresponding to all uplink logical channels. However, in the third embodiment, the manner in which the terminal device allocates resources for the uplink logical channel corresponding to the RLC status report is different from the second embodiment.

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

The third embodiment is different from the second embodiment in the resource allocation process. Specifically, in the third embodiment, the uplink resource allocation process is roughly divided into two rounds. The first round is to allocate resources to the first set of uplink logical channels, that is, the terminal device allocates resources according to the first set of uplink logical channels. In the configuration priority of each uplink logical channel in the first uplink logical channel set, the uplink resource is allocated to the uplink logical channel in the first uplink logical channel set; the second round is the resource allocation for the second uplink logical channel set, that is, the first round is executed After resource allocation, if there are remaining uplink resources, the terminal device allocates uplink resources for 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 process in the second embodiment when the first round of resource allocation is performed, but the second round of resource allocation process in the third embodiment is different from that of the second embodiment. The second round of resource allocation process is the same. Therefore, the first round of resource allocation process of the third embodiment will be described below, and for the sake of brevity, the second round of resource allocation process of the third embodiment will not be repeated.

In the first round of resource allocation process, the terminal equipment according to the order of the configuration priority of each uplink logical channel in the first uplink logical channel set from high to low, in turn, report the RLC status of each logical channel according to the size of the RLC status PDU. resource allocation. Specifically, the terminal equipment is in the order of the configuration priority of each uplink logical channel in the first uplink logical channel set from high to low, and according to the second requirement, is the uplink logical channel in the first uplink logical channel set in order. The logical channel allocates the uplink resource. Wherein, when the uplink resource is allocated 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 herein as the first uplink logical channel. The resource allocated to the first uplink logical channel meets a second requirement, and the second requirement is: the resource allocated to the first uplink logical channel meets 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 channels are all sent and the uplink resources are not exhausted, resources can be allocated for the RLC status PDUs of the low-priority logical channels. That is, at this time, the terminal device can maximize the transmission of the RLC status PDU of the high-priority logical channel.

The third embodiment described above will be described below with reference to the accompanying drawings.

FIG. 7 shows a schematic diagram of another method for multiplexing uplink logical channels 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 that the UE has established 4 uplink logical channels, which are called LC1, LC2, LC3, and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device. According to the RRC configuration, the terminal device determines the configuration priority of the 4 logical channels in the order of LC1>LC2>LC3>LC4. At the same time, the terminal device can also determine each uplink logic PBR and BSD of the channel.

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

Step 1. Determine the candidate logical channel for this uplink transmission.

Similar to the embodiment shown in Figure 6, still assuming that the current LC2 and LC3 have RLC status reports to be transmitted, the first uplink logical channel set of this uplink transmission includes LC2 and LC3; assuming that the current LC1, LC2 and LC4 are all waiting To transmit data, the second uplink logical channel set for this uplink transmission includes LC1, LC2, and LC4. Wherein, the resource allocation priority of LC2 and LC3 in the first uplink logical channel set is higher than the resource allocation priority of LC1, LC2 and LC4 in the second uplink logical channel set.

Step 2: Perform the first round of resource allocation to allocate resources for the uplink logical channel corresponding to the RLC status report, that is, LC2 and LC3 in the first uplink logical channel set. Specifically, according to the order of configuration priority of LC2 and LC3, resources are allocated for the RLC status reports of LC2 and LC3 according to actual RLC status PDU size requirements.

Step 3.2: After the resource allocation of step 3.1 is completed, if there are remaining resources, the remaining resources are allocated to LC1, LC2, and LC4 in sequence according to the amount of remaining data and the amount of remaining resources. As shown in Figure 7, after the resource allocation for LC1 and LC2 is completed, assuming that there are no remaining resources, no more resources are allocated for LC4; but if the opposite is true, if resources are sufficient, resources can be allocated for LC4.

Optionally, as a fourth embodiment, the terminal device may set the resource allocation priority of the uplink logical channel to be transmitted with the RLC status report to be greater than or equal to the resource allocation priority of the uplink logical channel for which no RLC status report is to be transmitted. In addition, when allocating uplink resources, it is roughly completed in two rounds. For each round of resource allocation, resources are allocated in sequence according to the resource allocation priority of the logical channel. The first round allocates resources that meet the PBR, and the second round allocates resources according to the remaining amount of data to be transmitted.

Specifically, different from the previous three embodiments, in the fourth embodiment, S210 in the method 200 may specifically include: the terminal device sets the at least one uplink logical channel in the at least one uplink logical channel according to the bearer type of the at least one uplink logical channel Determine the first uplink logical channel set and the third uplink logical channel set, where the bearer of each uplink logical channel in the first uplink logical channel set includes an RLC status report, and each uplink logical channel in the third uplink logical channel set The bearer of does not include the RLC status report; the terminal device 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 first uplink logical channel set is consistent with the concept of the first uplink logical channel set in the previous three embodiments, and for any of the at least one uplink logical channel An uplink logical channel, if the uplink logical channel corresponds to the RLC status report to be transmitted, then 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 data to be transmitted, for example, The uplink logical channel is only used to carry data, so 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 the RLC status report to be transmitted and the data to be transmitted at the same time, the uplink logical channel belongs to the first uplink logical channel set instead of the second uplink logical channel set.

In addition, 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 third uplink logical channel set; and for the same uplink logical channel set The configuration priority of each uplink logical channel in the first uplink logical channel set may be determined as the 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 the resource allocation priority; The device 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 priority of each uplink logical channel. Specifically, the uplink resource allocation process can be roughly divided into two rounds. First, the first round of resource allocation process is introduced. The terminal device allocates resources that meet the PBR for the uplink logical channel. For all the uplink logical channels with Bj>0 in the first uplink logical channel set and the third uplink logical channel, resources are allocated in the order of resource allocation priority from high to low, and the resources allocated for each uplink logical channel can only meet the requirements of PBR The requirement is to allocate resources for the logical channel j according to the number of tokens Bj in the PBR token bucket corresponding to the logical channel j.

Specifically, the terminal equipment is in the order of the resource allocation priority of each uplink logical channel in the first uplink logical channel set and the third uplink logical channel set from high to low, and according to the PBR requirement, the first uplink logical channel The uplink resource is allocated to the uplink logical channel set and the uplink logical channel with the number of tokens Bj in the third uplink logical channel set greater than 0, where the PBR requirement is: the resources allocated to the third uplink logical channel satisfy the third uplink logical channel According to the PBR requirement of the channel, the third uplink logical channel is any uplink logical channel in the first uplink logical channel set and the third uplink logical channel set with the number of tokens Bj greater than 0.

For the uplink logical channel j allocated to the resource in the first round of resource allocation, the number of tokens Bj is subtracted from the size of all the MAC SDUs of the logical channel j that are multiplexed into the MAC PDU in the first round of resource allocation. .

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

Specifically, the resources remaining after performing the first round of resource allocation are referred to herein as the sixth uplink resource. If there is a sixth uplink resource in the uplink resource, the terminal device will follow the first uplink logical channel set and The resource allocation priority of each uplink logical channel in the third uplink logical channel set is from high to low, and the first uplink logical channel set and the uplink logical channel in the third uplink logical channel set are allocated in sequence. Six uplink resources.

The fourth embodiment described above will be described below with reference to the accompanying drawings.

FIG. 8 shows a schematic diagram of another method for multiplexing uplink logical channels according to an embodiment of the present application. As shown in Figure 8, it is assumed that the UE has established 4 uplink logical channels, which are called LC1, LC2, LC3, and LC4. In addition, the UE receives the RRC configuration sent by the network device. According to the RRC configuration, the terminal device determines the configuration priority of the 4 logical channels in the order of LC1>LC2>LC3>LC4. At the same time, the terminal device can also determine each uplink logic PBR and BSD of the channel.

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

Step 1. Determine the candidate logical channel and resource allocation priority for this uplink transmission.

Assuming that LC2 and LC3 have RLC status reports to be transmitted, and current LC1, LC2, and LC4 have uplink data to be transmitted, that is, LC2 and LC3 have RLC status reports to be transmitted, and LC1 and LC4 have no RLC status reports to be transmitted, then the current uplink is determined The transmitted first uplink logical channel set includes LC2 and LC3, and the third uplink logical channel set includes LC1 and LC4. The resource allocation priority of LC2 and LC3 in the first uplink logical channel set is higher than the resource allocation priority of LC1 and LC4 in the third uplink logical channel set. Therefore, the resource allocation priority of the four uplink logical channels is LC2>LC3>LC1>LC4.

Step 2: Perform the first round of resource allocation in the order of the resource allocation priority of the four uplink logical channels from high to low. Specifically, assuming that the number of tokens Bj of the four logical channels is greater than 0, the resources that meet the PBR are allocated to LC2, LC3, LC1, and LC4 in sequence, and the commands in the PBR token buckets of the four logical channels are updated according to the resource allocation results. Number of cards.

Step 3: After completing the first round of resource allocation, if there are remaining resources, continue to perform the second round of resource allocation, that is, allocate the remaining resources to LC2, LC3, LC1, and LC4 in sequence according to the remaining data amount and the remaining resource amount.

Optionally, in the case of determining the first uplink logical channel set and the third uplink logical channel set as described in the fourth embodiment, the resource allocation priority of the uplink logical channel in the first uplink logical channel set is higher. The principle of the uplink logical channel in the third uplink logical channel set, in addition to allocating uplink resources according to the method described in the fourth embodiment, other methods may also be used for resource allocation, and the embodiment of the present application is not limited to this.

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 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 still another method for uplink logical channel multiplexing according to an embodiment of the present application. As shown in Figure 9, similar to Figure 8, it is still assumed that the UE has established 4 uplink logical channels, which are called LC1, LC2, LC3, and LC4, respectively. In addition, the UE receives the RRC configuration sent by the network device. According to the RRC configuration, the terminal device determines the configuration priority of the 4 logical channels in the order of LC1>LC2>LC3>LC4. At the same time, the terminal device can also determine each uplink logic PBR and BSD of the channel.

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

Assuming that LC2 and LC3 have RLC status reports to be transmitted, and current LC1, LC2, and LC4 have uplink data to be transmitted, that is, LC2 and LC3 have RLC status reports to be transmitted, and LC1 and LC4 have no RLC status reports to be transmitted, then the current uplink is determined The transmitted first uplink logical channel set includes LC2 and LC3, and the third uplink logical channel set includes LC1 and LC4. The resource allocation priority of LC2 and LC3 in the first uplink logical channel set is higher than the resource allocation priority of LC1 and LC4 in the third uplink logical channel set.

Step 2: Perform the first round of resource allocation in the order of configuration priority of the uplink logical channels in the first uplink logical channel set from high to low. Specifically, assuming that the number of tokens Bj of LC2 and LC3 are both greater than 0, resources satisfying PBR are allocated to LC2 and LC3 in turn, and the number of tokens in the PBR token buckets of these two logical channels is updated according to the resource allocation result.

It should be understood that the minimum PDU size of the RLC status report in each embodiment of the present application may be a predefined value, for example, it may be a fixed value specified by the standard; or, the minimum PDU size of the RLC status report may also be The terminal device is sent from the RLC layer to the MAC layer, that is, the MAC entity is notified by the RLC entity, for example, it can be implemented through an interface between the RLC and MAC layers.

Therefore, according to the method for allocating resources for uplink logical channels in the embodiment of the present application, the terminal equipment according to the different logical channel bearer types, in the process of completing the uplink logical channel multiplexing according to the uplink transmission resources allocated by the network equipment, priority is given to the RLC status report Allocate resources so that the scheduling delay of RLC status reports can be reduced, and RLC express retransmission can be realized.
