  • Patent number: 11205845
    Abstract: A wireless radio communication apparatus and method in which directional transmission, also known as beamforming, training is performed on transmissions between multiple wireless radio communication devices participating in a local network. A sector level sweep (SLS) process uses transmitter sector sweep (TXSS) training, which includes transmitting a sector sweep (SSW) followed by generating sector sweep (SSW) feedback to other nodes in the local network, with optimum transmit sector information being exchanged between nodes. Embodiments include a power save mode, a delayed SSW feedback mode, and an embedded polling and feedback mode.

  • Patent number: 11076335
    Abstract: An apparatus and method for communicating via a routing protocol in a wireless network having directional transmission capabilities. Reliable peer stations are identified using Beamforming (BF) training feedback metrics. Routing discovery messages are transmitted by unicast to reliable peer stations, with neighborhood discovery lists disseminated among peer stations in a unicast mode. From the above information, routing tables are constructed with best routing between a source and a destination station, wherein messages can be routed using said routing table from a source peer station, through intermediate peer stations, to a destination peer station. In addition, other embodiments are described, including a simplified two-hop routing apparatus and method.

  • Patent number: 9948368
    Abstract: A wireless communication system with directional transmission for simultaneously relaying communications between an access point (AP) and multiple radio nodes in the network which are in a first category that supports multiple-input-multiple-output (MIMO) capability, or a second category having different signal processing capabilities. Utilizing a superframe, which is a modification of an existing protocol, a relaying service period (SP) controls multiple simultaneous training and data transmission frames. The AP selects a relay device from the radio nodes based on metrics selected from signal strength, estimation of air time, category of radio node, AoA/AoD, power connectivity. This allows data to be communicated in a MIMO hop from said AP to the selected relay device, with a multi-user (MU) MIMO hop from the selected relay device and a destination radio node (client).

  • Patent number: 9877350
    Abstract: Beamformed directional wireless communications are described that provide for spatial re-use that allows multiple pairs of peer-to-peer (P2P) links to communicate simultaneously over the same channel in the same spatial vicinity, without contention, and independent of centralized control. The spatial re-use improves network throughput by sharing spectrum resource among multiple links. Beamformed training includes obtaining best sector and least sector information by all stations. Prior to performing an independent P2P communication, antenna array sector information is checked, to assure that the sector to be selected is not impinging interference on other P2P interactions, then a request is made to a target station. The target station also refers to its sector information, and if no conflict is found it accepts and acknowledges the request, upon which it receives the P2P communication.
