Abstract: Systems, methods, and devices for device-to-device (D2D) distributed scheduling are disclosed herein. User equipment (UE) is configured to measure a received power level for a reference signal received from a target UE and measure received power levels for reference signals received from one or more non-target UEs. The UE is configured to generate a resource usage map for the target UE and the one or more non-target UEs. The UE is configured to determine a priority, with respect to the target UE, for each resource element group based on the resource usage map and an anticipated signal-to-interference ratio (SIR). The UE is configured to transmit data to the target UE during one or more resource element groups with the highest priorities for the target UE.

The apparatus of the HEW station includes circuitry configured to: generate a HE preamble comprising a legacy signal (L-SIG) field followed by a HE-SIG-A1 field, wherein the HE-SIG-A1 field is encoded individually. The circuitry may be further configured to transmit the HE preamble on at least one from the following group: multiple subcarriers of a sub-channel and multiple sub-channels. The circuitry may be configured to transmit the HE preamble with a cyclic prefix (CP) of the HE-SIG-A field that is longer than 0.8 micro-seconds (μs).
