Patent ID: 8717938

Claim:
A method for configuring user equipments (UEs) to send a sounding reference signal, comprising: notifying user equipments, by a base station, to a-periodically send a sounding reference signal, and sending configuration information down to the UEs for the UEs to a-periodically send the sounding reference signal (SRS); wherein, sending configuration information down to the UEs further comprising: through a downlink control information the base station carrying an indication information of the sounding reference signal for the user equipments a-periodically sending to the base station; and through a higher layers signaling the base station configuring N resources or ways for the UEs sending the sounding reference signal a-periodically; wherein N is an integer from 1 to 20; wherein the indication information indicates whether the user equipments needs to a-periodically send the sounding reference signal on the uplink component carrier and through which one of the N resources and ways to perform the sending; so that the user equipments a-periodically send the sounding reference signal on an uplink component carrier according to the received indication information.
