    Abstract: 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 (Access Indication Channel, AICH, message), sent by the base station, is received by each WTRU. The received RACH response signal comprises a control portion (Physical downlink control channel, PDCCH), and a data portion (Physical downlink shared channel, PDSCH). The 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. Blind decoding.

    Abstract: An apparatus for receiving system information updates includes a wireless transmit receive unit (WTRU) configured to receive a system frame number. The WTRU is also configured to receive system information messages in a modification period. The modification period has a boundary determined by the system frame number. The WTRU is configured to receive system information change notification after a first modification change boundary and determines that the system information is valid until a second modification change boundary.

    Abstract: 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.

    Abstract: Methods and apparatus are described for providing compatible mapping for baekhaul 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 devolved Node-B (eNB)) for mapping 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 (MFJMS) 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.
