摘要： A wireless communication method and apparatus are disclosed for assigning different phases, (i.e., time periods), to perform data transmissions over designated frequency bands in a cooperative relaying system. In phase 1, a relay station (RS) listens to a wireless transmit/receive unit (WTRU) and successfully receives b information bits. In phase 2, the RS and WTRU cooperatively transmit these b information bits to the destination. These transmissions may be performed in a unicast scheme, wherein a WTRU sends information to a selected RS in phase 1, and the RS forwards the information to a base station (BS) in phase 2. The transmission may also be performed in a multicast scheme, wherein the WTRU sends information to the RS and the BS in phase 1, and the RS transmits a subset the information to the BS in phase 2.

摘要： A method and apparatus for cooperative relaying in wireless communications is provided. An efficient and simplified relay scheme is disclosed that transitions between different modes on a per packet basis using scheduling information or switching information included in the packet, without requiring link reconfiguration. The cooperative relay scheme benefits further from the use of cooperative relaying protocols that emphasize centralized scheduling. One protocol emphasizes physical layer cooperation via synchronized transmissions and distributed space-time coding and the other protocol emphasizes medium access control (MAC) layer cooperation using different MAC flows or messages.

摘要： A method and an apparatus for sending a signal on a contentious feedback channel for a downlink shared service and for estimating a number of wireless transmit/receive units (WTRUs) are disclosed. When a transmission criterion associated with a physical random access feedback channel (P-RAFCH) is satisfied, a physical resource is randomly selected among a plurality of physical resources assigned for the P-RAFCH and a pre- configured signal is sent using the selected physical resource. A Node-B receives the pre-configured signal from a plurality of WTRUs and calculates a number of the WTRUs based on a number of used physical resources. The transmission criterion is at least one of successful reception of a data packet on a downlink physical channel, successful reception of a data block on a data service, reception of a signaling command, occurrence of a measurement event, and failure to receive a transmission after a specified number of times.

摘要： A method for network coding of packets between End Nodes (ENs) and a Relay Node (RN) in wireless communications can be performed at the RN. This method may include: receiving a new packet at the RN from one of the ENs; determining the source node of the new packet at the RN; providing a buffer for each EN; determining whether the buffer associated with the EN that is not the source of the new packet (non-source buffer) has the new packet buffered and based upon such determination, either: (1) storing the new packet in the EN buffer that is the source of the new packet on a condition that the non-source buffer is empty; or (2) network coding the new packet with an existing packet in the non-source buffer.

摘要： Method and apparatus for controlling a transmit power of a mobile station are disclosed. Mobile stations in direct communication on a cross link (XL) receive control parameters from a base station. A first mobile station (a receiving mobile station) may calculate a correction parameter for power offset for transmissions from a second mobile station (a transmitting mobile station) to the first mobile station, and send it to the second mobile station. The correction parameter may be generated within the maximum and minimum limits. The second mobile station may calculate a transmit power level for a transmission to the first mobile station based on the correction parameter, measurements on resources allocated for cross links for mobile station-to-mobile station direct communications, an interference measurement received from the first mobile station, and a path loss to the first mobile station.
