Embodiment Construction

[0027] In order to better understand the spirit of the present invention, it will be further described below in conjunction with some preferred embodiments of the present invention.

[0028] First of all, in order to facilitate the explanation and understanding of the present invention, it needs to be explained that the terms "serving base station", "non-serving base station", "cooperative base station" and "non-cooperative base station" in the present invention are all relative to a user equipment In terms of. Wherein, "serving base station" refers to a base station currently providing communication services for a user equipment, and other base stations other than the "serving base station" are "non-serving base stations" for the user equipment. "Coordinated base station" refers to a base station that performs coordinated multi-point with the user equipment, and "non-cooperative base station" refers to a base station that does not perform coordinated multi-point with the user...

Abstract

The invention provides a method for measuring a sounding reference signal (SRS) in a coordinated multi-point (CoMP) and equipment, wherein the SRS is sent by user equipment of a serving base station to a coordinated base station. The method comprises the following steps: receiving a CoMP request that is sent by the serving base station and is used for multi-point coordination of the user equipment; carrying out CoMP SRS configuration on the user equipment based on the CoMP request and sending CoMP SRS configuration information to the serving base station; and receiving the SRS sent by the user equipment. With utilization of the method, a problem that the coordinated base station can not measure or can not accurately measure an SRS sent by user equipment of a serving base station can be solved. Moreover, the provided method and the equipment are suitable for various CoMP scenes; and further development and application of the CoMP technology can be promoted greatly.

Description

technical field [0001] The present invention relates to a method and equipment for measuring SRS (Sounding Reference Signal, SRS) in Coordinated Multi-Point (CoMP, Coordinated Multi-Point), and in particular to a user equipment corresponding to a serving base station participating in Coordinated Multi-Point A method and device for enhancing the measurement of SRS sent by other coordinated non-serving base stations (coordinated base stations). Background technique [0002] The SRS is an uplink reference signal, which is mainly used for measuring channel state information (Channel States Information, CSI) of an uplink (Uplink, UL) in an FDD / TDD system. In addition, due to the mutual dissimilarity of the uplink and downlink channels in the TDD system, the SRS is also used in the TDD system to obtain downlink (Downlink, DL) channel state information. The SRS usually occupies the last symbol of an uplink transmission subframe, and may also occupy symbols in an uplink pilot time ...
