摘要:
One exemplary embodiment exploits the non-uniformity of the interference at the downlink STA to maximize the full-duplex MU UL OFDMA transmission throughput performance. A first exemplary technology adjusts the transmit power of the uplink STAs so that the interference caused at the downlink STA is uniform (or substantially uniform) across OFDMA sub-channels. By doing so, the AP can optimize uplink transmission performance (e.g., aggregate link throughput) without degrading downlink transmission performance (e.g., in terms of the MCS used). A second exemplary technology uses OFDMA transmission for downlink, even if there is only one downlink STA, and adjusts the MCS for each downlink sub-channel based on the interference caused by UL STAs on each sub-channel. This allows the DL throughput to be maximized (and higher than a single 20MHz OFDM transmission).

摘要:
An example implementation may include transmitting, by a first base station to a second base station, a beam-specific power down request value for one or more beams. Another example implementation may include receiving, by a second base station from a first base station, a beam-specific power down request value for one or more beams, and decreasing, by the second base station, transmit power for one or more transmit beams based on the beam-specific power down request value for the one or more beams.

A user equipment (UE) performing transmit power control (TPC) transmission slot assignment includes a receiver, a determining means and a slot allocator. The UE receives one or more TPC commands from two or more radio links, determines a TPC combining period in accordance with a primary slot position, wherein a primary TPC symbol transmission of the primary radio link is present at the primary slot position; a slot allocator that allocates a secondary slot position for a secondary TPC symbol transmission of the secondary radio link in accordance with the TPC combining period. A method and a radio base station are also included herein.

摘要:
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine separate uplink (UL) power limitations for multiple transmission time interval (TTI) durations based on distinct power control parameters. In some cases, an adjustment factor or a power backoff may be applied to communications using one TTI duration to ensure that total transmit power does not exceed a threshold. The UE and the serving base station may also identify one or more demodulation reference signal (DMRS) windows. UL data transmissions may be demodulated based on a DMRS sent during the same window. Transmit power control (TPC) commands may be applied at the beginning of each window. However, if an UL transmission is scheduled at the beginning of the window, the UE may wait until a DMRS transmission or until no more transmissions are scheduled for the window before applying the TPC adjustment.
摘要:
A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device determines when a first transceiver chain of the wireless device is to receive a first data signal. The wireless device then transmits a second data signal via a second transceiver chain of the wireless device based at least in part on the determination. The wireless device further suspends the transmission of the second data signal in response to the determination that the first transceiver chain is to receive the first data signal.
