Abstract

The present invention provides a cell processing method, a terminal device, and a network device, wherein the cell processing method includes: sending MAC CE signaling to the terminal device, and the MAC CE signaling is used to activate a secondary cell; according to the MAC CE signaling , activating the downlink SP RS; sending the downlink SP RS to the terminal device according to the sending time of the downlink SP RS, and the downlink SP RS is used for the terminal device to activate the secondary cell. The solution of the present invention enables the terminal equipment to obtain the downlink SP RS for activating the secondary cell in time after demodulating the MAC CE signaling, thereby avoiding increasing the activation time of the secondary cell and improving resource utilization.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a cell processing method, terminal equipment and network equipment. Background technique [0002] In the future-oriented fifth-generation (5Generation, 5G) mobile communication system, in order to improve the reliability of the 5G system, it is necessary to adjust the frequency offset, time offset, Doppler frequency shift, Doppler spread, and delay of the 5G system. Expansion, etc. for accurate estimation. At the same time, in order to reduce the signaling overhead, the reference signal should be avoided to appear all the time, and a tracking reference signal (Tracking Reference Signal, TRS) can be introduced. At the receiving end, the channel parameters can be accurately estimated according to the periodic TRS to improve the accuracy of demodulation. [0003] In order to improve spectrum efficiency and meet the demand for higher peak rates, carrier aggregati...
