摘要： Devices and methods that support two-stage sensing are disclosed. A STA in accordance with the disclosure may comprise a transmitter and a receiver. The receiver may receive, from an initiating STA, a first probe request including physical (PHY) layer capabilities associated with a first sensing. The transmitter may transmit, to the initiating STA, a non-trigger based NDP. The receiver may then receive, from the initiating STA, first sensing information based on the non-trigger based NDP and an indication that the initiating STA requests a second sensing. Next, the transmitter may transmit, to a plurality of multi-user (MU) sensing STAs, a second probe request, wherein the second probe request includes PHY layer capabilities associated with the second sensing. The transmitter may then transmit, to the plurality of MU sensing STAs, a trigger-based NDP to enable the plurality of MU sensing STAs to perform the second sensing based on the trigger-based NDP.

摘要： Device discovery at long ranges using directional antenna patterns for both transmission and reception of discovery beacon messages and discovery beacon response messages. Omnidirectional band transmissions to assist aiming a directional antenna are also described. Further, discovery beacons that include only those information elements which are necessary for device discovery are discussed, as well as separate scheduling beacons. The discovery beacon may include more robust encoding to increase discovery range or may be transmitted using a narrower channel to improve signal to noise ratio.

摘要： Techniques may be used for interference measurement and management in directional mesh networks, including centralized and/or distributed approaches. A centralized node, such as an operations and maintenance (OAM) center, may use feedback from nodes in the mesh network to partition the nodes in the mesh network into clusters based on interference levels. Interference measurement reports may be used by the centralized node to update cluster membership. An initiating node in the mesh network may use topographical information to generate an initial interference cluster, and interference measurement frame (IMF) scheduling information may be used to schedule transmissions within the interference clusters. Techniques for opportunistic measurement campaigns, simultaneous measurement campaigns, link failure detection, and link re-acquisition in directional mesh networks may also be used.

Embodiments may include transmitting, by a first STA, data to a second STA during one or more link intervals (LIs) in a scheduling interval (SI) of a mesh super-frame.

摘要： A method and apparatus are disclosed for communication in a Millimeter Wave Hotspot (mmH) backhaul system which uses mesh nodes. A mmH mesh node may receive a control signal which includes a total number of available control slots. The mesh node may determine the number of iterations of a resource scheduling mechanism that can be made during the time period of all available control slots, based on the number of neighbor nodes for the mesh node. Further, the mesh node may receive control slot information, including information about traffic queues and priorities. The mesh node may then perform resource scheduling using the resource scheduling mechanism based on the currently received control slot information and control slot information received in previous iterations of resource scheduling. The mesh node may also adjust a preamble based on a time between a last packet transmission and a current packet transmission to a neighboring node.
