Abstract: Embodiments of a system and method for beamforming in a Wireless Network are generally described herein. In some embodiments, an enhanced Node B (eNB) transmits to User Equipment (UE), from a plurality (Nc) of antenna ports of a plurality (Nt) of transmit antennas, a data signal where signal power is allocated in eigen beams, each of the Nt transmit antennas having antenna ports that are adjustable in elevation and in azimuth. The eNB also determines and transmits to the UE a Pc set of the largest principal eigen beams of the data signal and receives, as feedback from the UE, a precoding matrix that identifies the antenna port from which strongest energy in the data signal is detected at the UE. The eNB uses the precoding matrix for beamforming.

Abstract: A user equipment (UE) can reserve shared spectrum between two wireless protocols upon the request from a tower. For example, an enhanced node B (eNB or eNodeB) transmits a message to associated UEs including a set of candidate UEs, a length of time to reserve, and a frequency band to use. UEs perform medium sensing on the specified spectrum if a UE finds its identifier in the set of candidate UEs. Candidate UEs transmit a clear to send (CTS) message with channel reservation information if the medium is idle. A result of the success or failure of the CTS transmission attempt is sent back to the eNB. Upon receiving the feedback information from the UEs, the eNB starts sending data to those UEs that sent the positive feedback on the channel reservation.

Abstract: Embodiments of an access point (AP) may comprise memory and processing circuitry coupled to the memory, and transceiver circuitry coupled to the processing circuitry. The processing circuitry of the AP may be configured to encode a trigger frame to allocate a center 26 tone RU of an 80 MHz channel for an HE-trigger-based PPDU, the center 26 tone RU having an adjacent upper 20 MHz subchannel and an adjacent lower 20 MHz subchannel. In an embodiment, the center 26 tone RU is for a station (STA) and wherein the trigger frame indicates to the STA to transmit a pre-HE-STF preamble on one of the adjacent upper 20 MHz subchannel, the adjacent lower 20 MHz subchannel, or both the adjacent upper and lower 20 MHz subchannels, and configure the wireless device to transmit the trigger frame to the station.

Abstract: Techniques for improving CSI (Channel State Information) in connection with FD (Full Dimension)-MIMO (Multiple Input Multiple Output) are discussed. A first set of techniques can employ hierarchical cell common class B CSI-RS for improved beam selection. A second set of techniques can provide improved CSI feedback based on eigenvalue(s) and co-phase associated with a precoder. Various embodiments can employ either or both of the first set of techniques and/or the second set of techniques.
