    摘要: A method and apparatus for combined medium access control (MAC) and radio link control (RLC) processing are disclosed. For uplink processing, a combined MAC/RLC (CMR) entity generates an SDU descriptor and allocates protocol data unit (PDU) descriptor resources. A protocol engine (PE) populates a PDU descriptor for each PDU carrying at least a portion of the SDU and generates a MAC PDU in a physical layer shared memory based on the SDU descriptor and the PDU descriptor. The MAC PDU is generated while moving RLC SDU data from the bulk memory to the physical layer shared memory. For downlink processing, received MAC PDUs are stored in the physical layer shared memory. The PE reads MAC and RLC headers in the MAC PDU and populates an SDU segment descriptor (SD) and corresponding PDU descriptors for each SDU segment. The CMR entity merges SDU SDs that comprise a same RLC SDU.

    摘要: A method and apparatus for neighbor discovery in a wireless communication system are disclosed. A neighbor seeking wireless transmit/receive unit (WTRU) may send a first beacon based on configuration information provided by the network. The neighbor WTRUs receive the first beacon and may send either a report to the network or send a second beacon to the neighbor seeking WTRU. The network may then provide neighbor WTRU information to the neighbor seeking WTRU. The neighbor discovery may be performed within a pre-defined group of WTRUs that is formed based on proximity to the WTRU and/or an attribute of the WTRU. The neighbor discovery procedure may be performed to find neighbor WTRUs in case where a WTRU fails to find any network. A neighbor list may be generated by the neighbor seeking WTRU by measuring reference signals transmitted by neighbor WTRUs on an uplink to the network.

    摘要: A method and apparatus for establishing peer-to-peer communication and performing forwarding under the control of a cellular network are described. A seeking wireless transmit/receive unit (WTRU) may receive a timing signal from at least one discoverable WTRU controlled by a base station. The seeking WTRU may estimate the quality of a radio link (i.e., path loss) between the seeking WTRU and the discoverable WTRU, and determine, (e.g., based on a threshold established by the base station), whether or not to report the estimated radio link quality to a base station that controls the discoverable WTRU. The power of the timing signal may be ramped up in predetermined steps such that the transmission power at any given time is known and may be used by the seeking WTRU for estimating the radio link quality. The timing signal may include at least one of a primary preamble or a secondary preamble.

    摘要: Data traffic may be mapped such that it may be routed via a component carrier. The data traffic may be mapped based on QoS, traffic offload, or the like. This may provide the ability to map certain data to specific component carriers. For example, this may provide a user subscription model with the ability to map one or more services to license exempt (LE) carriers, but not to other carriers. As another example, a user downloading a high definition movie may not want this to be counted towards his or her monthly quota on a licensed carriers or may want to pay flat rate to access supplementary carriers for such services. Allowing data to be mapped such that it may be routed via a component carrier via a component carrier may allow the user to map the data for the high definition movie to a LE carrier.
