Embodiment Construction

[0129] figure 1 It is a schematic diagram of a communication system applied in the prior art. Such as figure 1 The communication scene shown includes: terminal device A, terminal device B, and access network equipment. After establishing a communication connection with the access network equipment, the terminal equipment can further communicate with the core network through the access network equipment. For example, in figure 1 In the example shown, it shows that when the access network device is base station E, within the coverage of base station E, both terminal device A and terminal device B can access base station E, and through the established wireless connection relationship Communicate with base station E. The communication includes: the terminal equipment sends uplink communication data to the base station, and the base station sends uplink communication data to the terminal.

Abstract

The invention provides a TA determination method and device for a terminal device. The method comprises the steps: a TA scaling factor, a subcarrier spacing parameter and a first TA are determined after the terminal device receives a TA adjustment parameter transmitted by an access network device and determines that the TA needs to be adjusted, so as to jointly adjust the first TA to obtain a second TA; when the terminal equipment determines the second TA, the TA adjustment parameter k is added, therefore, the TA adjustment method and device can be applied to determining the TA of the terminaldevice when the terminal device communicates with the satellite base station, and the terminal device can adjust the TA under the condition that the terminal device and the satellite base station jointly cause device movement.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for determining a timing advance (timing advance, TA) of a terminal device. Background technique [0002] When a terminal device communicates with an access network device (eg, a base station), if the distance between the terminal device and the access network device is relatively long, the uplink communication data sent by the terminal device to the access network device will have a large transmission delay. Therefore, the access network device will set a timing advance (TA) for the terminal device, so that the terminal device can obtain the first time of receiving the downlink communication data of the access network device through TA, and communicate with the terminal device to access The negative offset (negative offset) between the second times when the network equipment sends the uplink communication data. Furthermore, the terminal device can sen...
