In order to facilitate understanding of the embodiments of the present application, the relevant logical channel (Logical Channel, LCH) parameters of the present application will be described.

Based on the uplink resources configured by the network device, the terminal device needs to determine the amount of data to be transmitted on each logical channel in the initial transmission Media Access Control Protocol Data Unit (MAC PDU). In some cases, the terminal device also needs to allocate resources for the Media Access Control Element (MAC CE). In order to achieve multiplexing of logical channels, each logical channel needs to be assigned a priority. For a MAC PDU of a given size, when multiple logical channels have data transmission requirements at the same time, resources for the transmission of the MAC PDU are allocated in descending order according to the priority corresponding to each uplink logical channel.

In order to take into account the fairness between different logical channels, the concept of Prioritized Bit Rate (PBR) is introduced. When the terminal device performs logical channel multiplexing, it is necessary to first ensure the minimum data rate requirement of each logical channel, so as to avoid This is a situation where other logical channels with low priority of the terminal device are "starved" because the logical channel with high priority always occupies the uplink resources allocated by the network device to the terminal device.

In order to realize the multiplexing of logical channels, network equipment configures the following parameters for each logical channel through Radio Resource Control (RRC) signaling:

Logical channel priority (priority), the smaller the priority value, the higher the corresponding priority;

PBR indicates the minimum rate that needs to be guaranteed for the logical channel;

Bucket size duration (bucketSizeDuration, BSD), this parameter determines the depth of the token bucket corresponding to the logical channel.

The Media Access Control (MAC) layer of the terminal device uses the token bucket mechanism to implement logical channel multiplexing.

Specifically, the terminal device maintains a variable Bj for each logical channel j, which indicates the number of tokens currently available in the token bucket corresponding to the logical channel. The number of tokens is set as follows:

(1) When the terminal device establishes logical channel j, it initializes Bj to 0;

(2) Before each logical channel priority (Logical Channel Prioritization, LCP) processing, the terminal device increases Bj by PBR*T, where T is the time interval from the last time Bj was increased to the current time;

(3) 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 terminal device receives an uplink grant (UL grant) indicating a new transmission, the terminal device performs LCP processing according to the following steps:

Step 1: For all logical channels with Bj>0, resources are allocated in order from high to low priority. The resources allocated to 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 in allocates resources to this logical channel. Optionally, when the PBR of a certain logical channel is set to infinity, only when the resources of this logical channel are satisfied, a logical channel with a lower priority than this logical channel will be considered.

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

Step 3: If there are remaining uplink resources after performing steps 1 and 2, regardless of the size of Bj, the remaining resources will be allocated to each logical channel in order from high to low logical channel priority. Only when the data of the high-priority logical channel has been sent and the UL grant has not been exhausted, the low-priority logical channel can be served. That is, the terminal device maximizes data transmission on high-priority logical channels.

At the same time, the MAC layer of the terminal device should follow the following principles when forming packets:

1. If the entire Radio Link Control (RLC) SDU can be filled in the remaining resources, the RLC SDU should not be segmented;

2. If the terminal device segments the RLC SDU in the logical channel, it should try to fill in the largest segment according to the size of the remaining resources;

3. Terminal equipment should maximize data transmission;

4. If the UL grant size is greater than or equal to 8 bytes, and the terminal device has data transmission requirements, the UE cannot only send a padding buffer status report (Buffer Status Report, BSR) or only padding.

For different signals and/or logical channels, the terminal equipment also needs to follow the following priority order when performing LCP processing (arranged in order from high to low priority):

Cell Radio Network Temporary Identity (C-RNTI) MAC CE or data from the Uplink Common Control Channel (Uplink Common Control CHannel, UL-CCCH);

Configured Grant Confirmation MAC CE;

Used for BSR MAC CE except padding BSR;

Single Cell (Single Entry) Power Headroom Report (PHR) MAC CE or Multiple Cell (Multiple Entry) PHR MAC CE;

Data from any logical channel except UL-CCCH;

MAC CE for Recommended bit rate query;

BSR MAC CE for padding BSR.

In the 5G network, the concept of Quality of Service (QoS) flow is introduced. Figure 2 is a schematic diagram of a QoS model in the 5G network.

Specifically, after the UE accesses the 5G network through the Uu interface, it establishes a QoS flow for data transmission under the control of the SMF entity. The SMF entity provides the QoS flow configuration information of each QoS flow to the base station, including code rate requirements and delay requirements. , bit error rate requirements and other information. For each QoS flow, the base station schedules wireless resources according to the QoS flow configuration information received from the SMF entity to ensure the QoS requirements of the QoS flow.

In the 5G network, a QoS flow can transmit both the uplink data stream (the data stream sent by the UE to the peer device through the 5G network) and the downlink data stream (the data stream sent by the peer device to the UE through the 5G network). , here the peer device may refer to the peer application server or the peer UE. The delay requirements for the upstream and downstream data flows in a QoS flow are the same. If the upstream and downstream data flows of a certain service have different latency requirements, they will be transmitted through different QoS flows. The delay here refers to the data transmission delay between the UE and UPF.
