摘要： Methods and apparatus are described for providing compatible mapping for backhaul control channels, frequency first mapping of control channel elements (CCEs) to avoid relay-physical control format indicator channel (R-PCFICH) and a tree based relay resource allocation to minimize the resource allocation map bits. Methods and apparatus (e.g., relay node (RN)/evolved Node-B (eNB)) formapping of the Un downlink (DL) control signals, Un DL positive acknowledgement (ACK)/negative acknowledgement (NACK) and/or relay-physical downlink control channel (R-PDCCH) (or similar) in the eNB to RN (Un interface) DL direction are described. This includes time/frequency mapping of above-mentioned control signals into resource blocks (RBs) of multimedia broadcast multicast services (MBMS) single frequency network (MBSFN)-reserved sub-frames in the RN cell and encoding procedures for these. Also described are methods and apparatus for optimizing signaling overheads by avoiding R-PCFICH and minimizing bits needs for resource allocation.

摘要： A method and apparatus for supporting a random access using a random access channel (RACH) are disclosed. Each of a plurality of wireless transmit/receive units (WTRUs) sends a random access request to a base station on an uplink RACH preamble. A RACH Response, sent by the base station, is received by each WTRU. A control signal portion of the RACH Response indicates the location of the RACH Response message portion. The RACH Response control signal comprises multiple control channel elements (CCE), where each WTRU is allocated a respective CCE to provide its unique RACH Response control signal. The WTRU is configured to locate its intended CCE from among the multiple CCEs sent by the base station.

摘要： A method and apparatus are provided for multi-cell cooperation when multiple cells are cooperating to transmit data to a plurality of wireless transmit/receive units (WTRUs), and each cell is using a common precoding matrix. The level of information exchanged among the cells may depend on the particular cooperation architecture. The cells may share information such as channel state information (CSI), a channel quality indicator (CQI), or both. The cells may share rank indications reported by the WTRUs. The cells may also share the data that is being transmitted to the WTRUs. The method and apparatus may also determine precoding vectors for closed-loop precoding; a CQI, CSI and rank, and distributed space-time/frequency coding with multi-cell cooperation. The method and apparatus may also perform hybrid automatic repeat request (HARQ) with multi-cell cooperation, and downlink control signaling.
