Embodiment Construction

[0054] In the embodiment of the present invention, when the network side determines that the uplink air interface resources are insufficient, it sends downlink reference signals to all user equipments, and notifies all user equipments to perform channel measurement according to the downlink reference signals, and notifies all user equipments to cancel or reduce the uplink reference signals. The sending of the signal.

[0055]Wherein, the density of the uplink reference signals is: the density of the uplink reference signals that needs to be configured when performing channel measurement based on the uplink reference signals; the all user equipments are: all user equipments that need to upload the uplink reference signals.

[0056] In the embodiment of the present invention, all the user equipments mentioned are: user equipments that need to complete "user discovery, measurement or channel estimation" through reference signals; and for some static ones, it is not necessary to pe...

Abstract

Disclosed is a method for configuring a reference signal. The method comprises: when a network side determines that uplink air-interface resources are insufficient, the network side sends a downlink reference signal to a user equipment, instructs the user equipment to measure according to the downlink reference signal, and instructs the user equipment to cancel or to reduce sending of uplink reference signals. Also disclosed are a device for implementing the method and a base station.

Description

technical field [0001] The present invention relates to channel measurement technology in the communication field, in particular to a reference signal configuration method, device, base station and user equipment. Background technique [0002] Currently, it is an important candidate technical solution of the 3GPP R12 Small Cell Enhancement project that the small base station monitors the user's uplink sounding reference signal (Sounding Reference Signal, SRS) for small base station discovery. Relevant discussions point out that the future Small Cell can not only discover small base stations based on downlink symbols and reference signals such as the primary synchronization signal / secondary synchronization signal, cell-specific reference signal (CRS) and reference signals like the traditional LTE system, but also can The discovery of the small base station is realized by monitoring the user's uplink SRS by the small base station, so as to solve the interference problem of a l...
