Method and apparatus for selecting and reselecting an uplink primary carrier
Abstract
A method and apparatus are described for using an uplink (UL) primary carrier for long term evolution-advanced (LTE-A) to support hybrid automatic repeat request (HARQ) feedback, a channel quality indicator (CQI), a scheduling request (SR), power headroom, and at least one buffer status report in the context of asymmetrical deployment and symmetrical deployment. A method, implemented by a wireless transmit/receive unit (WTRU), for multi-carrier operations, includes transmitting control information on a physical uplink shared channel (PUSCH) on a condition that PUSCH transmissions are occurring on at least one of multiple uplink component carriers (UL CCs), and transmitting the control information on a physical uplink control channel (PUCCH) on a condition that the PUSCH transmissions by the WTRU are not occurring on any of the multiple UL CCs.
