Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus of a device-to-device (D2D) link receives from a base station an indication of an acceptable level of interference that the base station can tolerate on an uplink resource. The uplink resource is allocated to a user equipment (UE) for a wide area network (WAN) transmission. The acceptable level of interference is a level of interference that the base station can tolerate on the uplink resource while the base station receives the WAN transmission from the UE. The apparatus determines a level of interference to the UE's transmission at the base station and performs a D2D communication on the uplink resource allocated to the second UE for the WAN transmission if the determined level of interference is less than the acceptable level.

Abstract: Methods and apparatus for reducing and/or eliminating the effect of self-interference are described. Various described methods and apparatus are well suited for use in DSRC WAVE systems in which a wireless communications device may acquire and use two DSRC channels, e.g., use one channel for reception while using another channel for transmission at the same time. A wireless communications device which is receiving a signal of interest on a first channel supports concurrent transmission on second channel, e.g., an adjacent channel. Controlled transmission timing synchronization with respect to the received signal of interest facilitates interference estimation and removal. Interference due to spillover energy from the transmission on the adjacent channel is estimated and removed from a received signal to facilitate recovery of the signal of interest.

Abstract: Power efficient methods and apparatus for detecting wireless terminals in a relatively small geographic area are described. Wireless terminals transmit discovery signals and/or other signals which may be detected by an access point. Various described methods and apparatus are well suited for embodiments where multiple access points, which obtain power from a common power source and/or via a common power bus, with limited power delivery capability. To address power constraints, access points are controlled by a gateway device coupled to the access points so that one or more access points perform monitoring at different times with one or more access points having their receivers powered off while another access point monitors for wireless terminal signals. Power consumption from the common power source is managed by controlling power consumption associated with monitoring operations performed by one or more access points coupled to a common power source.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling distributed frequency synchronization based on a fastest node clock rate. In one example, a first UE is equipped to determine that a fastest clock rate is faster than an internal clock rate of the first UE by more than a first positive offset, and adjust the internal clock rate based on the determined fastest clock rate. In an aspect, the fastest clock rate is associated with a second UE of one or more other UEs from which synchronization signals may be received. In another example, a UE is equipped to obtain GPS based timing information, adjust an internal clock rate based on the GPS based timing information, and transmit a synchronization signal at an artificially earlier time in comparison to a scheduled time of transmission associated with the adjusted internal clock rate.

Abstract: A user equipment (UE) device includes a VLC receiver including a photodiode and a radio receiver. The UE device supports a plurality of alternative technologies, communications protocols, and/or frequencies. During a first mode of operation, e.g., a discovery mode, a low reverse bias voltage value is applied to the photodiode. The low reverse bias voltage is adequate to support the recovery of small amounts of communicated information, and the power consumed by the battery of the UE device is relatively low. During discovery, information communicated includes, e.g., a light transmitter ID, an access point ID, services available at the access point, configuration information for a light receiver and/or for an auxiliary radio receiver. During a second mode of operation, e.g., a data traffic mode, the reverse bias voltage applied to the photodiode is set to a high reverse bias voltage to support higher data rate using VLC.

Abstract: Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).
