    摘要: Providing for base station (BS) acquisition in semi-planned or unplanned wireless access networks is described herein. By way of example, a signal preamble can be dynamically allocated to wireless signal resources, such that the preamble is scheduled to different resource(s) across different cycles of the signal. Dynamic allocation can be pseudo-random, based on collision feedback, or determined by a suitable algorithm to mitigate collisions from a dominant interferer. In addition, dynamic scheduling can be particular to a type of BS to significantly reduce collisions from BSs of disparate types. In at least one aspect, a preamble resource can be sub-divided into multiple frequency sub-carrier tiles. Control channel information can be transmitted on each tile of a group of such tiles, further mitigating effects of a dominant interferer on a subset of the tile group.

    摘要: Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell-specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning subframes. Resource elements within the positioning subframe can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, portions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.

    摘要: Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. For example, the bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UEs may use the bitmap to control their operation. For example, a UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. In another aspect, a base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UEs communicating with the relay station.

    摘要: Techniques for supporting peer-to-peer (P2P) communication in a wide area network (WAN) are disclosed. In an aspect, interference coordination between P2P devices engaged in P2P communication and WAN devices engaged in WAN communication may be performed based on a network-controlled architecture. For the network-controlled architecture, P2P devices may detect other P2P devices and/or WAN devices and may send measurements (e.g., for pathloss, interference, etc.) for the detected devices to the WAN (e.g., serving base stations). The WAN may perform resource partitioning and/or association for the P2P devices based on the measurements. Association may include selection of P2P communication or WAN communication for a given P2P device. Resource partitioning may include allocation of resources to a group of P2P devices for P2P communication. The WAN may send the results of association and/or resource partitioning to the P2P devices, which may communicate in accordance with the association and/or resource partitioning results.

    摘要: Techniques for determining resources to use for peer-to-peer (P2P) communication are disclosed. In an aspect, a network entity may receive feedback information (e.g., resource usage information and/or channel state information) from P2P devices and may perform resource partitioning based on the feedback information to allocate some of the available resources for P2P communication. The allocated resources may observe little or no interference from devices engaged in wide area network (WAN) communication. In another aspect, P2P groups may perform resource negotiation via a WAN connection (e.g., with little or no involvement by the WAN) to assign the allocated resources to different P2P groups. In yet another aspect, a device may autonomously determine whether to communicate with another device directly or via a WAN, e.g., whether to initiate P2P communication with another device and whether to terminate P2P communication. In yet another aspect, a network entity may participate in resource negotiation by P2P devices.

    摘要: Techniques for performing interference management to support peer-to-peer (P2P) communication in a wide area network (WAN) are described. In an aspect, interference management may be performed in a coordinated manner for/by a set of server nodes, which may include a P2P server and at least one neighbor server node of the P2P server. The P2P server may be a UE communicating peer-to-peer with at least one other UE or P2P client. Interference management may be performed for the set of server nodes to reduce interference to the P2P server and/or the at least one P2P client. In one design, active sets may be determined for UEs. The active set of each UE may include nodes received with sufficient strength by that UE. The set of server nodes may be determined based on the active sets of the P2P server, the at least one P2P client, and possibly other UEs.

    摘要: Techniques for supporting communication in an asynchronous TDD wireless network are described. In an aspect, downlink transmissions and uplink transmissions may be sent on different carriers in an asynchronous TDD wireless network to mitigate interference. In one design, a station (e.g., a base station or a UE) may send a first transmission on a first carrier in a first time period and may receive a second transmission on a second carrier in a second time period. The station may only transmit, or only receive, or neither in each time period. In one design, allocation of carriers for the downlink and uplink may be performed when strong interference is detected, e.g., by a base station or a UE. When strong interference is not detected, the first and second carriers may each be used for both the downlink and uplink.
