摘要： A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. An enhanced uplink medium access control (MAC-e/es) entity processes a received scheduling grant to calculate a serving grant. The MAC-e/es entity determines whether both a hybrid automatic repeat request (H-ARQ) process for scheduled data and scheduled data are available. If an H-ARQ process for scheduled data and scheduled data are available, the MAC-e/es entity determines whether a serving grant exists. The MAC-e/es entity calculates a remaining power based on maximum allowed power and restricts an E-DCH transport format combination (E-TFC) based on the remaining power. The MAC-e/es entity selects an E-TFC using the serving grant and generates a MAC-e protocol data unit. The MAC-e/es entity may process the received scheduled grant is at each transmission time interval or may store the received scheduled grant in a grant list until there is E-DCH data to transmit.

摘要： A wireless transmit/receive unit (WTRU) receives a downlink subframe having multiple component carriers, each component carrier having control information encoded in a physical downlink control channel (PDCCH). The WTRU performs a blind decoding of control information in a first PDCCH located within a first component carrier to obtain a location of a second PDCCH located within a second component carrier, where the location of the second PDCCH is relative to a location of the first PDCCH as control channel element offset. The WTRU decodes the second PDCCH at the obtained location.

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 for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.
