Uplink signal transmitting and receiving method and device in a wireless communication system

摘要

A method and an apparatus for transmitting and receiving an uplink signal by a mobile terminal in a wireless communication system are provided. The first mobile terminal includes a receiver configured to receive, from a base station, a power control variable determined based on an interference value for a first receive beam used in order to receive an uplink signal of the first mobile terminal from among a plurality of receive beams of the base station, to receive, from the base station, neighboring receive beam allocation data indicating whether any of the receive beams in the plurality of receive beams, different from the first receive beam, is being used for uplink signal reception, to determine an uplink transmit power value based on the received power control variable and neighboring receive beam allocation data, and to transmit an uplink signal to the base station by using the determined uplink transmit power value.

主权项

1. A method for transmitting an uplink signal by a first mobile terminal in a wireless communication system, the method comprising:
receiving from a base station, a power control variable determined based on an interference value for a first reception beam used for reception of the uplink signal of the first mobile terminal among multiple reception beams of the base station; receiving from the base station, neighboring reception beam allocation information indicating whether to use other reception beams different from the first reception beam among the multiple reception beams for reception of the uplink signal; determining an uplink transmission power value based on the received power control variable and the received neighboring reception beam allocation information; and transmitting the uplink signal to the base station based on the determined uplink transmission power value.
