Method for transmitting power headroom report, and apparatus for same

摘要

Disclosed are a method for transmitting a power headroom report (PHR) and a terminal apparatus for same. The method for transmitting a PHR from a terminal in a network, which includes a base station and at least one cooperative node performing cooperative communication with the base station, includes a step of determining a sounding reference symbol (SRS) transmission power for transmitting SRSs in a specific serving cell, wherein the determined SRS transmission power is a value determined for the transmission of the SRSs to a plurality of nodes including a first node corresponding to the base station and the at least one cooperative node.

主权项

1. A method of transmitting a power headroom report (PHR) by a user equipment (UE) in a network in which a base station and one or more cooperative nodes for performing cooperative communication with the base station exist, the method comprising:
determining a sounding reference signal (SRS) transmit power for transmitting a SRS in a specific serving cell; and determining a PHR value for the SRS by subtracting the determined SRS transmit power from a maximum transmit power value configured for the UE for the specific serving cell, wherein the determined SRS transmit power is a value for transmission to a plurality of nodes among a first node corresponding to the base station and one or more cooperative nodes.
