Abstract

The present invention provides a configuration method, a terminal and a network side device, belonging to the technical field of wireless communications, the configuration method applied to the network side device comprising the steps of: issuing configuration information, the configuration information being used for indicating an association relationship between a reference signal for channel detection and a downlink reference signal. In the invention, the terminals with the same association relationship adopt the same SRS resource, so that the feedback time delay can be reduced and the uplink overhead can be reduced in a high-capacity scene (such as a high-speed rail).

Description

technical field

[0001] The present invention relates to the technical field of wireless communication, in particular to a configuration method, a terminal and a network side device. Background technique

[0002] The existing uplink reference signalβ€”Sounding Reference Signal (SRS) configuration for channel sounding cannot meet the requirements of large-capacity and low-latency scenarios, such as high-speed rail scenarios. Specifically, each symbol (symbol) of the existing SRS can only have a maximum capacity of 4*12, a total of 48 terminals, and 3 uplink time slots in a 5ms subframe. If two symbols per uplink time slot are used for 4 antennas to send SRS in turn, then A maximum of 72 terminals can be accommodated in a 5ms subframe. According to the simulation results, the maximum cyclic shift (CS) is set to 2 in high-speed scenarios, otherwise intersymbol interference will occur. That is, a maximum of 12 terminals can be accommodated in a 5ms subframe, and the uplink overhe...
