Abstract
The present invention provides a massive carrier aggregating method performed by a terminal in a wireless communication system, the method comprising the steps of: controlling a plurality of sounding reference signal (SRS) transmission powers with respect to a plurality of SRS cells to be triggered, respectively; and simultaneously transmitting a plurality of SRSs relating to the plurality of SRS cells to be triggered to a network, wherein the plurality of SRS transmission powers are different from each other.
Claims16
A method for massive carrier aggregation in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- receiving a sounding reference signal (SRS) triggering message from a network;
- determining an SRS triggering target cell based on the SRS triggering message;
- and
- sending an SRS for the determined SRS triggering target cell,
- wherein the SRS triggering message comprises information indicative of a plurality of cells triggering an SRS in a massive carrier aggregation.
A method for massive carrier aggregation in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- coordinating a plurality of pieces of SRS transmission power for a plurality of sounding reference signal (SRS) triggering target cells, respectively;
- and
- sending a plurality of SRSs related to the plurality of SRS triggering target cells to a network simultaneously based on the coordinated transmission power,
- wherein the plurality of pieces of SRS transmission power is different.
A method for massive carrier aggregation in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- determining a transmission of a sounding reference signal (SRS) related to an (N-K) cell of N cells configured in the UE by a massive carrier aggregation based on transmission power;
- and
- sending at least one SRS related to the (N-K) cell to a network based on the determination,
- wherein the N is a natural number having a value of 2 or more and the K is a natural number having a value smaller than the N.
