Abstract

Provided are a wireless communication method, a terminal device and a network device, which can dynamically implement carrier activation or deactivation, reduce the effective time delay of carrier activation or deactivation, avoid unnecessary PDCCH monitoring and measurement by the terminal device, and reduce power consumption. The wireless communication method comprises the steps that the terminal device detects first DCI on a PDCCH search space corresponding to a first carrier, wherein a first information domain in the first DCI indicates a second carrier; and in response to the first DCI, the terminal device activates or deactivates the second carrier.

Description

[0001] This application is a divisional application with the application number 2019800340042 and the title of the invention "wireless communication method, terminal equipment and network equipment". technical field [0002] The embodiments of the present application relate to the communication field, and more specifically, to a wireless communication method, a terminal device, and a network device. Background technique [0003] Carrier Aggregation (Carrier Aggregation, CA) technology can enable a terminal device to use multiple component carriers to simultaneously transmit and receive data, improve data transmission rate, and improve system work efficiency. In the CA system, the activation and deactivation of the carrier can be implemented through Media Access Control Control Element (Media Access Control Control Element, MAC CE) signaling or based on timer (Timer) control. However, the MAC CE mode or the Timer-controlled carrier activation and deactivation mode has a certa...
