Abstract

The embodiment of the invention provides a transmission method, a base station and user equipment for measurement reference signals; the transmission method for the measurement reference signals comprises the following steps: user equipment is grouped; the numbers of the user equipment in group, measurement reference signal resources preserved for the group and a measurement resource unit included in the measurement reference signal resources are notified to the user equipment; a PDCCH (physical downlink control channel) transmits triggering information to the user equipment, wherein the triggering information comprises a triggering command part which is used for indicating the triggered user equipment in the group; therefore, the triggered user equipment can transmit the measurement reference signals on a searched measurement resource unit after finding out the measurement resource unit distributed for the triggered user equipment, so as to reduce demands on the measurement reference signal resources; beside, in the embodiment of the invention, the signaling expense of the PDCCH is low.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for sending a measurement reference signal, a base station, and user equipment. Background technique [0002] Long Term Evolution (hereinafter referred to as: LTE) and Long Term Evolution-Advanced (hereinafter referred to as: LTE-A) systems both use Single Carrier Frequency Division Multiple Access (Single Carrier Frequency Division Multiple Access) in the uplink; Abbreviation: SC-FDMA) access method. Taking the period of the SC-FDMA symbol as the basic time unit, the duration of each SC-FDMA symbol is about 1 / 14 millisecond. Each SC-FDMA symbol is divided into multiple subcarriers in the frequency domain, and the interval between subcarriers is set to 15kHz in the LTE protocol. [0003] In the LTE protocol, time-frequency resources are divided into uniform units called resource elements (Resource Elements; hereinafter referred to as...
