METHODS FOR POWER HEADROOM REPORTING, RESOURCE ALLOCATION, AND POWER CONTROL

摘要

A method of reporting power headroom for a user equipment (UE) to a base station is disclosed. The method comprises generating power headroom information by subtracting a first value associated with physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) transmit power from a second value associated with a maximum UE transmit power in a subframe if a simultaneous PUCCH and PUSCH transmission is allowed. Further, transmitting the power headroom information to the base station. The first value is generated based on nominal PUCCH power information, UE specific PUCCH power information, a value associated with a PUCCH format provided by RRC signaling, path-loss information, a PUCCH format dependent value and information based on power control information transmitted by the UE.
