摘要： Techniques for performing peer discovery to enable peer-to-peer (P2P) communication are disclosed. In an aspect, a proximity detection signal used for peer discovery may be generated based on one or more physical channels and/or signals used in a wireless network. In one design, a user equipment (UE) may generate a proximity detection signal occupying at least one resource block based on a SC-FDMA modulation technique. In another design, the UE may generate a proximity detection signal occupying at least one resource block based on an OFDMA modulation technique. The UE may generate SC-FDMA symbols or OFDMA symbols in different manners for different physical channels. In yet another design, the UE may generate a proximity detection signal including a primary synchronization signal and a secondary synchronization signal. For all designs, the UE may transmit the proximity detection signal to indicate its presence and to enable other UEs to detect the UE.

摘要： Systems and methodologies are described that facilitate employing flexible signaling of resource block assignments on a control channel. Resource blocks associated with an uplink or downlink channel can be split into a plurality of groups, and group-specific signaling constraints can be utilized with each of these groups. For example, the group-specific signaling constraints can relate to minimum resource block allocation units, signaling structures (e.g., bitmap structure, contiguous allocation structure, tree-based structure, . . . ), and the like utilized for sending assignment indications that allocate resource blocks within the respective groups. Further, an access terminal can have a common understanding of the group-specific signaling constraints; thus, a received assignment indication can be deciphered by the access terminal by utilizing the group-specific signaling constraints.

摘要： Method and apparatus for facilitating inter-cell connections, such as during a forward handover or radio link failure (RLF), are disclosed. A user terminal such as a UE may store identity information associated with a source cell, and use this information in accessing target or other cells subsequent to radio link failure so as to facilitate access to context information of the user terminal. A base station may be configured to improve handover performance by associating context information with a newly assigned terminal identity. Handover performance may be enhanced by facilitating connection processing in the event of inability to retrieve user terminal context from a source cell.

摘要： Methods and apparatuses are provided that facilitate allocating a portion of a resource block to a power-limited device for communicating therewith. The power-limited device may not be capable of transmitting over an entire resource block due to power limitations; thus, a portion of the resource block can be assigned thereto, allowing for allocating at least a different portion of the resource block to at least one different device to optimize communications over the resource block. In addition, the portion of the resource block can be allocated across one or more bundled time transmit intervals (TTI) to allow for effective communication of time-sensitive data, such as voice over internet protocol (VoIP).

摘要： Techniques for delivering data recovered by a HARQ entity in proper order to higher layers in a CDMA system. In a method, packets are received from the HARQ entity by the re-ordering entity and missing packets among the received packets are detected. Packets may be transmitted in a sequential order based on transmission sequence numbers (TSNs) assigned to the packets, and missing packets may be detected based on the TSNs of the received packets. Delivery of received packets later than the missing packets are stalled because higher layers expect data in-order. A determination is thereafter made whether each missing packet is (1) subsequently received from the HARQ entity or (2) lost, by successively eliminating HARQ channels that may be used to send the missing packet. Received packets previously stalled by each missing packet are delivered after the missing packet is determined to be lost or received.
