Problems solved by technology

[0005] However, in the current SRS resource allocation method, if the available frequency band of the UE located at the edge of the cell is limited, this factor is not considered when allocating the SRS bandwidth, so that the UE may be allocated SRS resources exceeding its available bandwidth, for example, let the UE Sending sounding reference signals on the full bandwidth every time, resulting in unnecessary waste of resources, resulting in the tension of SRS resources

Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] An embodiment of the present invention provides a method for allocating sounding reference signal SRS resources, see figure 1 , methods include:

[0024] 101: Obtain the cell area where the user terminal UE is currently located;

[0025] 102: Allocate SRS resources for the UE according to the frequency band resources allocated in the cell area by the inter-cell interference coordination ICIC algorithm.

[0026] The embodiment of the present invention provides a method for allocating SRS resources to allocate SRS resources for the UE in the frequency band divided by the cell area where the UE is currently located according to the ICIC algorithm, so as to improve the accuracy and efficiency of SRS resourc...

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...
