Abstract
A method, for a base station, for transmitting Position Reference Signals (PRS) in a wireless communication system is provided. The method comprises mapping PRS to Resource Elements (REs) of a frame structure, and transmitting the frame structure such that the power used to transmit REs containing PRS is higher than the power used to transmit REs not containing PRS. Methods, for a User Equipment (UE), for transmitting PRS in a wireless communication system are also provided. One method comprises measuring the signal strength from one or more base stations, and transmitting PRS with a power determined based on the measurements. Another method comprises receiving signaling from a base station, and transmitting PRS with a power determined based on the signaling.
Claims14
A method of operating a User Equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, configuration information for a sound reference signal (SRS), the configuration information including an offset;
- identifying path loss of a downlink from a non-serving cell based on the received configuration information for the SRS;
- determining a transmission power of the SRS based on the offset and the path loss of the downlink from the non-serving cell;
- in case that the determined transmission power of the SRS is lower than a predetermined maximum transmission power, transmitting the SRS based on the determined transmission power of the SRS.
(canceled)
A User Equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver;
- and
- at least one processor configured to:
- receive via the transceiver, from a base station, configuration information for a sound reference signal (SRS), the configuration information including an offset
- identify path loss of a downlink from a non-serving cell based on the received configuration information for the SRS,
- determine a transmission power of the SRS based on the offset and the path loss of the downlink from the non-serving cell, and
- in case that the determined transmission power of the SRS is lower than a predetermined maximum transmission power, transmit via the transceiver, the SRS based on the determined transmission power of the SRS.
