摘要： Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to transceivers and receivers for wireless communications are described. The various aspects include an apparatus of a communication device including an antenna array and processing circuitry coupled to the antenna array. The processing circuitry is configured to initialize a beam tracking algorithm based on received signals received at the antenna array, wherein antenna phases used in the beam tracking are bound by an upper phase limit and a lower phase limit, to generate a beam tracking result. The processing circuitry is further configured to generate a calibration vector based on the beam tracking result and receive subsequent transmissions using a codebook adapted based on the calibration vector.

摘要： A client station (STA), when operating in a wireless network, receives data sent by an access point (AP) on a first channel comprising at least one subchannel. During reception of the data on the first channel, the STA monitors channel availability of an additional set of one or more subchannels. In response to a detected availability of at least one newly-available subchannel, the STA sends at least one notification to the AP identifying STA-side availability of the newly-available subchannel(s). The STA subsequently receives data from the AP on the newly-available subchannel(s), which is sent in response to the at least one notification. The AP, when communicating data to the STA, receives the at least one notification from the STA and, in response thereto, initiates data transmission on one or more of the newly-available channel(s).

摘要： An array of antenna elements is energized as a plurality of concentric rings of the antenna elements, each of the concentric rings energized with a respective signal from a first transceiver, the signal having a continuously varying progressive phase between the antenna elements to generate n respective electromagnetic orbital angular momentum (OAM) beams each having a respective OAM mode m where m ranges from 0 to ±n. The beams are contemporaneously generated orthogonal to each other. The circumferential phase profile of the signal for a concentric ring of α antenna elements is 2πm radians, and the progressive phase difference between each of the α antenna elements is 2πm/α radians. The first transceiver transmits the beams to a second transceiver which demodulates them and sends demodulation quality information to the first transceiver for determination of whether to transmit the beams in full multiplexing, full diversity or partial diversity.

摘要： A technology for a user equipment (UE) is disclosed that is operable in an anchor-booster architecture of a multiple radio access technology (multi-RAT) heterogeneous network (HetNet). Control information to an anchor cell can be transmitted from a wireless wide area network (WWAN) node in the multi-RAT UE. Data packets of the multi-RAT UE can be selected for transmission via one of the WWAN node and a wireless local area network (WLAN) node in the multi-RAT UE using a multi-RAT coordination function (MRCF) module. Each data packet from one of the WWAN node and the WLAN cell can be transmitted to a multi-RAT small cell evolved node B (SC-eNode B) based on the selection by the MRCF module.

摘要： Techniques involving beamforming are disclosed. For example, For instance an apparatus may select a first mobile station served by a first base station and a second mobile station served by a second base station. Based on this selection, a quality metric may be determined that is based on a strength of a user link and a strength of an interfering link. The user link is associated with service of the first mobile station and the interfering link is associated with service of the second mobile station. When the quality metric is greater than a predetermined threshold, the apparatus may designate the first and second mobile stations as suitable for beamforming service in a same resource allocation. Also, techniques are disclosed for determining whether a mobile station is a cell edge mobile station.
