Abstract: Transmitting data via frame reconfiguration comprises encoding, at a source node, the data into a plurality of frame configurations, each of the plurality of frame configurations comprising a sequence of uplink and downlink subframes, and communicating, via an antenna of the source node, using the plurality of frame configurations, wherein a target node is configured to identify the plurality of frame configurations and decode the data.

Abstract: Systems and methods are described for enhanced multi-antenna transmission. At a multi-antenna system of a first access node, implicit transmit symbols are assigned to a plurality of antennas. At least two antennas are selected from the plurality of antennas to simultaneously transmit explicit symbols to a wireless device. The explicit symbols are used at the wireless device to decode the implicit transmit symbols.

Abstract: A transmit power level of a wireless device is adjusted based on an uplink interference to neighboring sectors caused by the transmit power level. The wireless device can estimate the uplink interference using a reference signal transmitted by each neighboring sector. The uplink interference is based on a loss of signal strength of the reference signal as measured at the wireless device, i.e. a path loss. A determination is made to adjust the transmit power level of the wireless device so as to improve a coverage area of the serving sector, without generating excessive interference in neighboring sectors. Consequently, a transmit power level increase is based on a function of the data demand of the wireless device, the interference caused to neighbors, and the load on neighboring sectors.
