    摘要: Methods, apparatuses, and computer program products are disclosed for encoding/decoding a wireless control signal. For encoding, control bits are received and encoded with a first error control code so as to create a first set of encoded bits. The encoded bits are then encoded with a second error control code so as to create a second set of encoded bits, which are modulated as beacon tones and subsequently transmitted. For decoding, beacon tones corresponding to a set of control bits are received and subsequently demodulated so as to ascertain a set of demodulated bits. The demodulated bits are then decoded with a decoder so as to ascertain a set of decoded bits. The decoded bits are then decoded with a second decoder so as to ascertain a second set of decoded bits, which includes the set of control bits.

    摘要: Techniques for mitigating interference on control channels in a wireless communication network are described. In an aspect, high interference on radio resources used for a control channel may be mitigated by sending a request to reduce interference to one or more interfering stations. Each interfering station may reduce its transmit power on the radio resources, which may then allow the control channel to observe less interference. In one design, a user equipment (UE) may detect high interference on radio resources used for a control channel by a desired base station. The UE may send a request to reduce interference on the radio resources to an interfering base station, which may reduce its transmit power on the radio resources. The UE may receive the control channel on the radio resources from the desired base station and may observe less interference from the interfering base station.

    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 establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon. In particular, the signals can be spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassignment value, which allows devices to utilize persistent channels in communicating data to one another.

    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 are disclosed. In an aspect, P2P communication may be supported with a symmetric waveform for a P2P downlink and a P2P uplink. In one design, a first UE generates a first signal based on a particular waveform (e.g., a downlink waveform or an uplink waveform for a wireless network) and transmits the first signal to a second UE for P2P communication. The first UE also receives a second signal generated by the second UE based on the particular waveform and transmitted to the first UE for P2P communication. In another aspect, a proximity detection signal may be transmitted in a portion of a subframe instead of the entire subframe. The remaining portion of the subframe may be used to transmit control information and/or other information to support P2P communication.
