Abstract: Methods, apparatus, and computer-readable media are described to use multi-finger beamforming for multimeter wave communications. A base station associates with first and second user equipment. Weight sum rates are determined for the user equipment. Transmissions are scheduled to the user equipment based on the weight sum rates. Data is encoded for the first user equipment and transmitted based on the schedule. Data is encoded for the second user equipment and transmitted based on the schedule. The transmissions are multiplexed in the power domain.

Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises baseband circuitry including one or more processors to decode a secondary synchronization signal (SSS) or a beam reference signal (BRS) received from an evolved Node B (eNB) to select a Tier-1 sector for receiving downlink transmissions from the eNB, decode a downlink control channel message received from the eNB at one or more fixed time offsets after the UE decodes the SSS to obtain index information for the Tier-1 sector to identify the Tier-1 sector, and if the Tier-1 sector has changed initiate a random access procedure to select an updated Tier-1 sector, and generate an updated Tier-1 sector index message to report to the eNB.

Abstract: In a radio access network, user equipment (UE) is to encode signaling for sector-sweep transmission to a base station via a plurality of directional beams in a millimeter-wave radio band over a random-access shared channel during at least one contention period, and determine a transmission power setting for the directional transmission. The transmission power setting is based on a targeted received signal characteristic to be achieved at the base station using a selected beam direction, and the transmission power setting is determined based on transmission parameters of the UE and reception parameters of the base station, and on channel characteristics. The UE is to initiate transmission of the signaling using the transmission power setting for the plurality of directional beams, wherein the signaling is transmitted to be received according to a targeted received signal characteristic to be achieved at the base station.

Abstract: 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).

Abstract: Embodiments of a system and method for selecting a duplex mode for a service operating in a Wireless Network are generally described herein. In some embodiments, a mobile device may receive one or more traffic packets related to an establishment or a re-establishment of a service at the mobile device, and may select a duplex mode for the service. In some embodiments, the mobile device may be an IEEE 802.11 Station (STA). The mobile device may be configured to select full-duplex as the duplex mode when a delay requirement associated with the service is less than a predetermined delay threshold and when a calibration overhead associated with the mobile device or the service is less than a predetermined calibration overhead threshold. In addition, the mobile device may also be configured to select time-division duplex (TDD) or frequency-division duplex (FDD) as the duplex mode when the delay requirement is less than the delay threshold and when the calibration overhead is less than the calibration overhead threshold.
