Abstract: Various aspects of the disclosure relate to communicating random access information and uplink control information. In some aspects, a user equipment (UE) or other suitable apparatus transmits physical uplink control channel (PUCCH) information concurrently with random access channel (RACH) information transmitted by another UE or other apparatus. For example, the RACH access information and the PUCCH information may be frequency division multiplexed orthogonal tones. The disclosure relates in some aspects to using downlink-uplink (DL-UL) channel reciprocity to determine symbol and/or tone locations. For example, a base station or other suitable apparatus may initially sweep across different directions in different time slots to transmit signals during a synchronization sub-frame. A UE or other suitable apparatus can then find an appropriate RACH symbol from its best synchronization beam index and transmit PUCCH information in those symbols.

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: 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.
