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.

Discontinuous reception (DRX) operations for wireless communications implementing carrier aggregation are disclosed. Physical downlink control channel implementation for carrier aggregation is also disclosed. DRX methods are disclosed including a common DRX protocol that may be applied across all component carriers, an individual/independent DRX protocol that is applied on each component carrier, and hybrid approaches that are applied across affected component carriers. Methods for addressing the effects of loss of synchronization on DRX, impact of scheduling request on DRX, uplink power control during DRX, and DRX operation in measurement gaps are disclosed.

A method and apparatus for detecting an overlap of an E-DCH transmission or retransmission in TTIs that overlap with an assigned uplink compressed mode gap is disclosed. More specifically, detecting an overlap of an E-DCH transmission or retransmission in TTIs that overlap with an uplink compressed mode gap assigned by a Node B when a WTRU is configured with a 2 ms TTI is disclosed. After detecting the overlap of the E-DCH transmission or retransmission and the uplink compressed mode gap, the E-DCH transmission or retransmission is paused.

摘要:
Techniques for component carrier-specific reconfiguration are disclosed. A wireless transmit/receive unit (WTRU) is capable of transmitting or receiving via multiple component carriers. The WTRU may perform component carrier reconfiguration on a component carrier basis to add, remove or replace a component carrier. Discontinuous reception (DRX) and/or discontinuous transmission (DTX) may be performed on at least one component carrier, wherein DRX and/or DTX patterns on the component carriers may not overlap each other. A random access procedure may be performed at the target cell on one component carrier while other component carriers are inactive. The component carrier-specific reconfiguration or handover of a component carrier or a channel may be implemented in coordinated multiple point transmission (CoMP), wherein a handover of a control channel, not a traffic channel, may be performed. Alternatively, a handover of a traffic channel may be performed.

摘要:
Methods of mapping, indicating, encoding and transmitting uplink (UL) grants and downlink (DL) assignments for wireless communications for carrier aggregation are disclosed. Methods to encode and transmit DL assignments and UL grants and map and indicate the DL assignments to DL component carriers and UL grants to UL component carriers are described. Methods include specifying the mapping rules for DL component carriers that transmit DL assignment and DL component carriers that receive physical downlink shared channel (PDSCH), and mapping rules for DL component carriers that transmit UL grants and UL component carriers that transit physical uplink shared channel (PUSCH) when using separate coding/separate transmission schemes.
