Title:
SIGNAL TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/221335
Kind Code:
A1
Abstract:
Provided are a signal transmission method and apparatus. The method comprises: a terminal device acquiring first configuration information and second configuration information, wherein the first configuration information is used for indicating a frequency hopping bandwidth configuration of a sounding reference signal (SRS), and the second configuration information is used for indicating a terminal-device-level SRS bandwidth configuration; and when the terminal device determines, according to the first configuration information and the second configuration information, to perform frequency hopping transmission on a first SRS, in the process of transmitting the first SRS, performing one instance of switching of an antenna for sending the first SRS each time when the detection of the whole cell-level SRS bandwidth is completed by using frequency hopping.
