| 发明名称 | Method and apparatus for random access in multicarrier wireless communications | ||
| 摘要 | Methods and apparatus for random access in multicarrier wireless communications are disclosed. Methods and apparatus are provided for physical random access channel (PRACH) resource signaling, PRACH resource handling, preamble and PRACH resource selection, random access response (RAR) reception, preamble retransmission, and transmission and reception of subsequent messages. A method for maintaining an allowed multicarrier uplink (UL) random access channel (RACH) configuration set by adding an UL carrier to the allowed RACH configuration set provided that a triggering event occurs and performing a random access (RA) procedure using the allowed RACH configuration set. A method for sending data in multicarrier wireless communications by determining a set of available UL carriers and selecting an UL carrier from the set of available UL carriers. | ||

| 主权项 | 1. A method implemented in a wireless transmit/receive unit (WTRU) for maintaining an allowed multicarrier uplink (UL) random access channel (RACH) configuration set, comprising: the WTRU adding an UL carrier to the allowed multicarrier UL RACH configuration set, on a condition that a triggering event occurs; and the WTRU performing a random access (RA) procedure using the allowed multicarrier UL RACH configuration set. | ||
