Embodiments of the present disclosure are described below with reference to the accompanying drawings. The service data transmission and information configuration methods, devices, terminals, and base stations provided in the embodiments of the present disclosure can be applied in wireless communication systems. The wireless communication system may be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as the 5G system). Those skilled in the art can understand that the 5G New Radio (New Radio, NR) system is only Example, not limitation.

First, some concepts related to the embodiments of the present disclosure are described as follows.

1. Extended Reality (eXtended Reality, XR) business and its transmission characteristics

XR and cloud game (Cloud Game, CG) are one of the most important 5G media applications. XR contains a variety of data frames, and each frame has its own transmission characteristics and transmission requirements. For example, I-frame (Intra-coded picture) is Intra-frame coding can represent a complete picture, and P-frame (Predicted picture) is inter-frame coding, which only needs to carry different information from the previous frame. Therefore, I-frame has a large amount of data and requires high reliability; P-frame has a small amount of data and has lower reliability requirements than I-frame. XR services have requirements for low latency, high throughput, and high reliability, and require large data transmission in a short period of time, which means that the burst throughput may be much higher than the average throughput in a short period of time. For example, the burst throughput of an XR service with an average throughput of 100 Mbps can reach 300 Mbps in a short measurement window, and high reliability must be ensured at the same time. XR is an umbrella term for different types of reality, and refers to all combined real and virtual environments and human-computer interactions generated by computer technology and equipment. It includes representative forms such as augmented reality (Augmented Reality, AR), mixed reality (Mixed Reality, MR) and virtual reality (Virtual Reality, VR). In the XR service, the service characteristic requirements are for data frames, for example, for scenarios and mixed video streams, the service characteristic requirements are: period 60 frames per second (frame per second, fps); data rate 10Mbps/20Mbps; packet delay budget ( Packet Delay Budget, PDB) 30ms (mandatory) or 10/15/60ms (optional).

High throughput requirements limit the capacity of XR services. For example, simulation results under typical cell deployments show that a cell supports more than a dozen XR service users.

2. switch

The handover process of the 5G system and the process related to the terminal are mainly in the first step, the handover measurement, the sixth step, the source cell initiates the handover (through the radio resource control (Radio Resource Control, RRC) synchronous reconfiguration command) and the eighth step, the handover to the target area. In the handover measurement, the source base station sends an RRC reconfiguration message to the terminal, and the RRC reconfiguration message includes target cell information and information about the terminal's access to the target cell including random access parameters. The handover initiated by the source cell includes a random access process between the terminal and the target base station and a process in which the terminal sends the RRC reconfiguration complete message corresponding to the RRC reconfiguration message from the source base station to the target base station to the target base station. After the source cell receives the RRC synchronization reconfiguration command and determines to switch to the target cell (the source cell initiates the switch), the terminal disconnects from the source cell and initiates synchronization to the target base station. Therefore, during the process from initiating the handover to completing the handover, service data transmission is interrupted.

5G introduces a handover optimized Dual Active Protocol Stack (DAPS) with zero interruption delay. During the handover process of the terminal, the terminal establishes a connection with the target cell while maintaining the connection with the source cell, and downlink data can be sent to the terminal through the source cell and the target cell. After completing the random access process with the target cell, the terminal only sends uplink data in the target cell, but can send uplink feedback and retransmission in the source cell. The specific description is shown in Figure 1.

The protocol stack of DAPS technology is shown in Figure 2. The terminal adopts a dual packet data convergence protocol (Packet Data Convergence Protocol, PDCP) protocol stack, corresponding to the source cell and the target cell respectively. The two PDCP entities perform duplicate packet detection and packet reordering functions in the same buffer (buffer), because the downlink data packets are sent separately through the two cells, and the same data packets may be sent or may arrive Different times will be out of order.

DAPS is only applied when both the source cell and the target cell are single cells, and neither Carrier Aggregation (CA) nor Dual Connectivity (DC) can be used during the DAPS process.

Among them, the method and the device are conceived based on the same application. Since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

As shown in FIG. 3, the embodiment of the present disclosure provides a service data transmission method applied to a terminal, including:

Step S301, receiving a radio resource control RRC reconfiguration message sent by the source base station indicating terminal handover or primary cell change;

Wherein, the RRC reconfiguration message includes the configuration of the first target resource used for target service transmission;

It should be noted that the target service mentioned in the embodiments of the present disclosure refers to a service that may have a high burst of large data transmission requirements during the handover process, that is, the target service will suddenly increase the data volume during the handover process of the terminal. For example, the target service is XR service; the handover mentioned in this disclosure refers to the scene of RRC synchronous configuration, including traditional handover and primary cell change, which can be understood as DAPS handover. Usually, the RRC reconfiguration The message needs to include a DAPS indication, which is used to indicate that the handover is a DAPS handover.

It should be noted that the source base station refers to the base station accessed by the terminal before handover.

Step S302, according to the RRC reconfiguration message, map the target service data to the corresponding first target resource for transmission;

The above items are for the terminal to configure additional resources under the source base station except the primary cell. For configuring the secondary cell under the source base station, It means that the CA is available during the DAPS handover process; for the SeNB corresponding to the configuration source base station, the primary cell under the SeNB, and the secondary cell under the SeNB, it means that the DC is available during the DAPS handover process.

It should be noted that when the first target resource includes the secondary cell under the secondary base station corresponding to the source base station, it can be considered that the terminal can use uplink resources and/or downlink resources of the secondary cell under the secondary base station corresponding to the source base station.

For configuring the secondary cell under the target base station, it means that during the DAPS handover process CA is available; for the secondary base station corresponding to the configuration target base station, the primary cell under the secondary base station, and the secondary cell under the secondary base station, it means that the DC is available during the DAPS handover process.

It should also be noted that when the first target resource includes a secondary cell under the secondary base station corresponding to the target base station, it can be considered that the terminal can use uplink resources and/or downlink resources of the secondary cell under the secondary base station corresponding to the target base station.
