Method and apparatus for enhancing cell-edge user performance and signaling radio link failure conditions via downlink cooperative component carriers


Abstract

A method and apparatus are described. A wireless transmit/receive unit (WTRU) includes circuitry that determines transmission power levels associated with physical uplink shared channel (PUSCH) transmissions over a plurality of uplink component carriers. On a condition that maximum power scaling is required, the circuitry prioritizes providing power to a physical uplink control channel (PUCCH) over providing power to a physical uplink shared channel (PUSCH) having uplink control information (UCI) and prioritize providing power to the PUCCH and PUSCH having UCI over a PUSCH not having UCI. The circuitry transmits the PUCCH, the PUSCH having UCI or at least one PUSCH not having UCI over the plurality of uplink component carriers.
