Abstract

The invention discloses a sounding reference signal resource allocation method, a system and a device, which belong to the field of the mobile communication. The method comprises the following steps that: the present community area of the user terminal UE is obtained; the frequency band resource which is allocated in the community area according to the inter-cell interference coordination ICIC algorithm is of an SRS resource which is allocated to the UE. The system comprises a base station. The device comprises a base station device. According to the restriction of the UE usable frequency band and the physical layer real-time interference measurement result of the ICIC algorithm, the accuracy and the validity of the SRS resource allocation are improved, and reference is provided to the service coordination by transmitting the quality of SRS sounding sub-channel.

Description

technical field

[0001] The present invention relates to the field of mobile communication, in particular to a method, system and equipment for resource allocation of sounding reference signals. Background technique

[0002] In the LTE (Long Term Evolution, long-term evolution) system cell, multiple UEs (User Equipment, user terminals) share time-frequency resources using PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel), and the scheduler follows the scheduling principle, such as The current channel quality of each sub-channel determines which time-frequency resources are allocated to which UEs in which time interval.

[0003] Among them, the estimation of the quality of each sub-channel is mainly through the UE sending an SRS (Sounding Reference Signal, Sounding Reference Signal) according to the sounding bandwidth and transmission power sent by the base station, and then the base station measures the channel quality according to the SRS. Since the SRS...
