Disclosed herein are apparatuses, systems, and methods using or implementing dynamic beamforming in control channels, by transmitting downlink control channels to user equipment (UEs) in a number of orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A first OFDM symbol of the number of OFDM symbols can be transmitted using first beamforming parameters in a first direction, and a second OFDM symbol of the number of OFDM symbols can be transmitted using second beamforming parameters different from the first beamforming parameters and in a second direction different from the first direction. The number of OFDM symbols used, as well as other parameters, can be dynamically adjusted in subsequent subframes. Other embodiments are described.

Resonator control techniques for wireless power transmitting units are described. One or more novel parameters may be defined for use in conjunction with dominant PRU selection on the part of a PTU. In various embodiments, each of a plurality of PRUs may determine values for one or more such parameters, and may report those values to the PTU. In some embodiments, the PTU may identify a parameter to be used as a selection criterion, and may identify the dominant PRU based on the respective values reported for that parameter by the plurality of PRUs. Other embodiments are described and claimed.

Devices and methods of providing symmetric UL and DL ACK/NACKs is generally described. UL ACK/NACKs of different UEs are multiplexed and received by a UE with a PUSCH. The receiving UE in response transmits the DL ACK/NACK. The ACK/NACK may be transmitted in a localized or distributed manner among subbands that may be adjacent or each may have blocks separated by blocks of a different subband. The ACK and NACK may use independent resources or the NACK may not be transmitted on the single ACK/NACK resource, the lack of an ACK serving as a NACK. The ACK/NACK may be transmitted using a beamforming weight shaped by the received PUSCH/PDSCH. The ACK/NACK symbol may be located in the first symbol, adjacent to the PUSCH/PDSCH, or at the end of a TTI. If adjacent, the UL grant or UL assignment may indicate whether the ACK/NACK resource is used by the PUSCH/PDSCH.
