Abstract: A station (STA) may include an antenna and a processor operatively coupled to the antenna. The antenna and the processor may be configured to receive a request message from an access point (AP). The request message may include identity information of one or more other STAs and an indication to perform measurements of the one or more other STAs. The antenna and the processor may be further configured to perform the measurements of the one or more STAs to determine a link metric associated with each STA of the one or more other STAs. The antenna and the processor may be further configured to send a reply message to the AP after the link metric associated with each STA of the one or more STAs is determined. The reply message may include results of the determination.

Abstract: 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.

Abstract: Methods and apparatus are described. A long term evolution (LTE) base station includes a processor and a transceiver, which transmit first LTE data to a wireless transmit/receive unit (WTRU) using LTE frequencies. The LTE data is at a time defined by LTE transmission time interval (TTI) boundaries. The processor maps an LTE class of second LTE data to an access class associated with IEEE 802.11e access and transmits the second LTE data to the WTRU using an IEEE 802.11 associated frequency. A transmission time of the second LTE data is based on an LTE TTI boundary after sensing that an IEEE 802.11 associated frequency is not busy.

Abstract: A method and apparatus for improving and performing mmW beam tracking is disclosed. Localization methods to improve prediction of the position of a WTRU are described, which may allow a millimeter wave base station (mB) to appropriately select a modified beam and to perform more efficient handover. WTRUs may report directional signal strength measurements to mBs, which may then be used to generate a directional radio environment map (DREM) for use in identifying secondary links to use when a primary link fails. Additional localization techniques using internal/external information for prediction are described. Historical data use and the use of data obtained from mB-mB cooperation including feedback information and reference signaling information are also described. Methods for beam tracking for directional relays and initial beam training optimization are described as well. Finally, WTRU localization precision improvement, beamwidth adaptation, and assisted beam tracking and handover methods are also described.

Abstract: A method to reserve a directional channel, such as in an unlicensed spectrum for instance, is disclosed. In an example embodiment, the method may be performed by a receiving node, such as a user equipment (UE) for instance. In such method, the receiving node may receive an enhanced directional transmit request message from a transmitting node and transmit an enhanced directional transmit confirmation message using one or more first beams, with at least one first beam being directed in a first direction towards the transmitting node. Further, the receiving node may transmit at least one additional enhanced directional transmit confirmation message using one or more second beams, with at least one second beam being directed in a second direction towards a potentially interfering node. In the method, the second direction is a different direction than the first direction.

Abstract: Systems, methods, and instrumentalities are disclosed herein for pre-processing for channel state information (CSI) compression in wireless system. A WTRU may receive configuration information that indicates a reference signal and a data processing model for channel state information (CSI) compression. The WTRU may determine CSI associated with a channel using the reference signal. The WTRU may determine a channel condition associated with pre-processing. The WTRU may select a pre-processing type from a plurality of pre-processing types based on the data processing model and the determined channel condition associated with pre-processing. The WTRU may pre-process the CSI associated with the channel based on the selected pre-processing type. The WTRU may generate compressed CSI by compressing the pre-processed CSI using the data processing model for CSI compression. The WTRU may send the compressed CSI to a network.
