Abstract

The invention discloses a method and a device for resource configuration of an uplink sounding reference signal (SRS). The method comprises the steps of: determining data transmission time of business data of a terminal by a network element of an access network; configuring uplink SRS resources and SRS resource effectiveness time for the terminal by the network element of the access network according to the data transmission time, wherein the SRS resources and the effectiveness time are used for indicating that the terminal is only allowed to transmit the SRS by using the SRS resources within the effectiveness time; and transmitting the configured SRS resources and the effectiveness time to the terminal by the network element of the access network. According to the invention, on one hand, the terminal can be ensured to transmit the SRS by using the SRS resources within the effectiveness time without increasing extra signaling expense, and on the other hand, the SRS resources can be ensured to be used by other terminals within the time beyond the effectiveness time, so that the utilization rate of the SRS resources is improved.

Description

technical field

[0001] The present invention relates to the field of communications, in particular, to a resource configuration method and device for an uplink sounding reference signal. Background technique

[0002] In a broadband wireless communication system, in order to assist a network element of an access network in performing uplink channel estimation and measurement, a user equipment (User Equipment, UE for short) needs to send an uplink reference signal. Orthogonal sequence codes are generally used for uplink reference signals to reduce mutual interference of uplink reference signals between different UEs. The network element of the access network obtains the uplink channel quality of different UEs by measuring the uplink reference signals of different UEs, and performs frequency-selective radio resource scheduling for the UEs based on this. In addition, the uplink reference signal can also assist uplink synchronization. For example, in the third-generation mobile ...
