Transmission method of TA in wireless communication, electronic equipment and storage medium

Abstract

The invention discloses a TA transmission method in wireless communication, electronic equipment and a storage medium, and relates to the technical field of wireless communication. The transmission method comprises the steps that after TA measurement and calculation are completed, when the base station prepares to issue TA adjustment amount to the user terminal, whether pdsch data transmission exists between the base station and the user terminal or not is judged, if yes, the base station issues the TA adjustment amount to the user terminal along with the pdsch data, otherwise, a TA issuing time window is set, and it is judged that the TA adjustment amount is within the TA issuing time window; whether pdsch data transmission exists between the base station and the user terminal or not is judged, if yes, the base station issues the TA adjustment amount to the user terminal along with the pdsch data, and if not, the base station independently issues the TA adjustment amount to the user terminal. According to the invention, the TA issuing time window is set, and when the TA is sent along with the pdsch data, pdsch and pdsch resources are saved, so that the spectrum utilization rate of the base station is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a TA transmission method, electronic equipment and storage medium in wireless communication. Background technique [0002] In a wireless communication system, TA is the timing advance of UE terminal uplink channel (PUSCH / PUCCH / SRS / DMRS) signal transmission. The base station calculates the difference between the expected TA value and the currently measured TA value by measuring the uplink timing advance of the uplink channel (PUSCH / PUCCH / SRS / DMRS), and sends the TA value that needs to be adjusted in advance or delayed to the terminal , so as to adjust the TA of the terminal, so that the signal transmitted by the uplink channel of the terminal reaches the base station within the expected time alignment range, so that the base station completes the reception and demodulation of the uplink channel. [0003] The trigger condition for base station TA adjustment...

Problems solved by technology

It can be seen that in the existing TA adjustment value transmission method, as long as there is a TA that needs to be delivered, the PDCCH and PDSCH will be consumed, so that the spectrum utilization rate of the base station is low.
