    Abstract: Hybrid beam-forming (BF) radio communications are carried out between a base station (BS) and a set of user equipment (UEs) within a service area. The hybrid BF operations include a sector-sweep operation to identify analog beam-forming (BF) parameters for individual ones of the set UEs within the service area. A first subset of UEs is selected from among the set of UEs, the first subset of UEs being subject to channel quality assessment (CQA). The UEs of the first subset are configured to transmit CQA signaling, the CQA signaling being based on the analog BF parameters. Digital BF parameters are computed for the UEs of the first subset based on the CQA signaling.

    Abstract: Logic may beamform a set of collaborative access points (C-APs) to facilitate spatial reuse. Logic may transmit a collaborative beamforming (CBF) announcement to initiate CBF and to inform the stations of the order of channel sounding by and identifiers for access points (APs) in the set. Logic may transmit channel sounding and receive one or more feedback reports in response. Logic may transmit one or more report polls to trigger the feedback reports from the remaining stations associated with the set. Logic may request more extensive channel information from primary stations associated with an AP and less extensive channel information from secondary stations associated with the AP. Logic may transmit channel information from each AP in the set for each primary and secondary station. Logic may transmit the channel information to a central server to schedule simultaneous transmissions between multiple APs and multiple primary stations on a channel.

    Abstract: A technology that is operable to schedule data transfer for a multiple user multiple-input and multiple-output (MU-MIMO) communications network is disclosed. In one embodiment, an enhanced node B (eNode B) is configured with circuitry configured to receive a sounding signal from each of a plurality of user equipment (UEs). One or more major paths of the sounding signals from each of the plurality of UEs are determined. An angle of arrival (AoA) is determined that is associated with each of the one or more major paths. The plurality of UEs are grouped into one or more candidate MU-MIMO sets using the AoAs associated with each of the one or more major paths. Data transmissions are scheduled for one or more of the candidate UEs of the candidate MU-MIMO set on one or more of the major paths of each of the candidate UEs.

    Abstract: Certain embodiments herein relate to scheduling interference between wireless devices in a manner that reduced interference associated with full duplex communication. Signal strength and interference information associated with communication between wireless devices may be collected and forwarded to a processing device, such as a central controller. The central controller may utilize such information to generate a conflict graph that depicts interference relationships between the wireless devices. Using the conflict graph, the central controller may determine whether requested communications may be scheduled along with concurrently scheduled communications without resulting in interference affecting the communications. In one embodiment, a requested communication may be scheduled with other concurrently scheduled communications if the aggregated throughput is increased with the addition of the requested communication.

    Abstract: Methods, apparatus, systems and articles of manufacture to enable spatial reuse in a wireless network are disclosed. An example apparatus includes a beamforming report collector to collect a plurality of beamforming reports. An access point and mobile station pair identifier is to include a first access point and mobile station pair in a collaborative beamforming set. The access point and mobile station pair identifier is to identify a second access point and mobile station pair based on one of the plurality of beamforming reports. An interference estimator is to estimate an amount of interference caused by inclusion of the second access point and mobile station pair in the collaborative beamforming set. The access point and mobile station pair identifier is to add the second access point and mobile station pair to the collaborative beamforming set when the estimated amount of interference is less than an interference threshold.
