    摘要： A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.

    摘要： Disclosed embodiments pertain to a method on a UE may comprise determining a first absolute position of the UE at a first time based on GNSS measurements from a set of satellites. At a second time subsequent to the first time, the UE may determine a first estimate of displacement of the UE relative to the first absolute position using non-GNSS measurements. Further, at the second time, the UE may also determine a second estimate of displacement relative to the first absolute position and/or a second absolute position of the UE based, in part, on: the GNSS carrier phase measurements at the first time from the set of satellites, and GNSS carrier phase measurements at the second time from a subset comprising two or more satellites of the set of satellites, and the first estimate of displacement of the UE.

    摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a serving base station. The serving base station receives channel feedback from a plurality of UEs. The channel feedback is based on predetermined phase rotations used by the serving base station. The serving base station selects at least one UE of the UEs for a data transmission based on the received channel feedback. The serving base station maps at least one data stream to a set of resource blocks. The serving base station transmits the set of resource blocks to the at least one UE with a phase rotation determined based on the predetermined phase rotations.

    摘要： Methods and apparatus for determining a portion of a channel, e.g., a peer discovery channel, to use in a communications network, e.g., an ad hoc peer to peer network, are described. In the communication network, the channel includes a recurring set of time/frequency resources. A device monitors the congestion level and decides to use a whole channel or a fraction of a channel (e.g., ½. ¼) as a function of the congestion level. The device may change the fraction of the channel it occupies as the congestion level changes. The device broadcasts control information indicating the fraction of the channel it occupies. The device may be a mobile wireless terminal.

    摘要： Efficient methods for wirelessly communicating file content under varying conditions are described. A wireless device determines, based on mobility and/or geographic location, if the wireless device is to operate in a first mode of communication operation in which received portions of said file are re-transmitted or a second mode of communication operation in which combinations of portions of said file are transmitted. The wireless device transmits packets communicating received file portions when it is determined that the wireless device is to operate in said first mode of operation and transmits packets communicating combinations of file portions, e.g., linear combinations of file portions, when it is determined that the wireless device is to operate in said second mode of operation. The contents of a file may be obtained from some packets which communicate distinct portions of the file and other packets which communicate combinations of distinct portions of the file.
