Abstract

The present application provides a transmission method, a terminal device, and a network device. The transmission method includes: the method includes: after the terminal device receives the first message sent by the network device for instructing to activate a secondary carrier cell, send a message to the network device sending a second message, where the second message is used to indicate a preset time; the terminal device receives a third message sent by the network device according to the preset time, where the third message is used to indicate triggering resynchronization of the secondary carrier cell. The transmission method of the present application helps to quickly save the time for triggering the resynchronization of the uplink secondary carrier cell and improve the uplink throughput.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a transmission method, terminal equipment and network equipment. Background technique [0002] As the carrier aggregation (Carrier Aggregation, CA) industry matures day by day, there are more and more demands on uplink CA. In order to solve the uplink CA demodulation performance in different coverage scenarios, the protocol introduces Multiple Timing Advances (Multiple Timing Advances, MTA). Moreover, MTA-based uplink two-carrier aggregation has been gradually commercialized. For example, South Korea's LG U+ has been successfully commercialized, and multiple operators are actively preparing for testing, and commercialization is imminent. According to the protocol, after the terminal device receives the message of activating the secondary carrier, there is a delay in the activation taking effect, and the maximum support is 34ms. [0003] For uplink 2 carrier cell (Ca...
