    摘要: Techniques for configuring and switching a resource assignment mode for a plurality of component carriers are disclosed. A wireless transmit/receive unit (WTRU) has a capability of supporting multiple resource assignment modes such that a resource assignment mode is configured for a plurality of component carriers that are allocated for the WTRU, and the WTRU attempts to decode a control channel based on the configured resource assignment mode. The resource assignment mode may be configured for the WTRU via higher layer signaling. The resource assignment mode may be specific to the WTRU, or specific to a component carrier or a group of component carriers. The resource assignment mode may be configured separately for a downlink component carrier and an uplink component carrier. The resource assignment mode includes a separate assignment mode with component carrier indication, a separate assignment mode without component carrier indication, or a joint assignment mode.

    摘要: A method of decoding enhanced uplink absolute grant channel (E-AGCH) transmissions in a wireless transmit/receive unit (WTRU). E-AGCH data is received, the E-AGCH data including a cyclic redundancy check (CRC) part and a data part, the CRC part having been masked with a WTRU identity (ID). The CRC part and the data part are demultiplexed and the CRC part is demasked with a first WTRU ID. A first CRC is performed with the data part and the CRC part demasked with the first WTRU ID. The data part is decoded on a condition that the first CRC passes.
