Title:
COMMUNICATION METHOD AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/164514
Kind Code:
A1
Abstract:
The present application provides a communication method and a communication device. The method comprises: a terminal device acquires an uplink timing advance (TA) of a service cell; the terminal devices acquires a downlink signal time difference between the service cell and an adjacent cell; the terminal device acquires, based on the uplink TA of the service cell and the downlink signal time difference, an uplink TA of the adjacent cell; and based on a downlink subframe timing and the uplink TA of the adjacent cell, the terminal device sends an uplink signal to the adjacent cell. The uplink TA of the adjacent cell is acquired such that the terminal device can send an uplink signal to the adjacent cell based on the uplink TA of the adjacent cell. In this way, the uplink signal sent by the terminal device aligns with an uplink reception timing of the adjacent cell, thereby reducing the interference of the uplink signal sent by the terminal device to the adjacent cell, and improving the communication property of the terminal device and the adjacent cell.
