Abstract:
1. A method for transmitting a sounding reference signal a periodically in a wireless communication system, comprising: configuring parameters of the sounding reference signal for a channel to be sounded by a user equipment so as to allocate resources of the sounding reference signal to the user equipment; transmitting, through a high layer signaling, information containing the resources of the sounding reference signal allocated to the user equipment to the user equipment; and transmitting, through a low layer signaling, an activation signal to the user equipment so as to activate the user equipment to transmit the sounding reference signal, wherein the parameters of the sounding reference signal comprise frequency resource of the user equipment, code division resource of the user equipment, a corresponding bit position of the user equipment in the low layer signaling or a number of times that the sounding reference signal being transmitted when the user equipment is activated, and wherein the low layer signaling activates one or more user equipments at one time, and if a plurality of user equipments are activated, the plurality of user equipments correspond to different bit positions from each other in the low layer signaling.
