Abstract: Methods, systems, and devices are described for wireless communication. A serving base station may transmit a signal to user equipment (UE) using directional beamforming. The UE may receive the transmission from the serving base station and may also receive a signal from a neighbor base station using directional beamforming. The UE may then generate an interference report based on the two transmissions, and send report to the serving base station. The serving base station may generate a local interference graph based on the interference report, exchange interference information with the neighbor base station(s), and schedule subsequent transmissions to the UE based on the exchanged interference information. In some cases, the scheduling is based on distributed information exchange and prioritization. In other cases, the scheduling may be managed by a centralized controller.

Abstract: A beamforming configuration is changed during a cyclic prefix that precedes a symbol period. For example, the beamforming configuration for a transmitter can be changed during an orthogonal frequency-division multiplexing (OFDM) cyclic prefix that precedes a fast Fourier transform (FFT) window. At the receiver, the cyclic prefix is reconstructed based on the chips received during FFT window. In this way, there is no loss of data signaling due to the transmitter reconfiguring its beamforming.

Abstract: 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.

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.
