Abstract: A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.

Abstract: Apparatuses, methods, and computer readable media for signaling high efficiency short training field are disclosed. A high-efficiency wireless local-area network (HEW) station is disclosed. The HEW station may comprise circuitry configured to: receive a trigger frame comprising an allocation of a resource block for the HEW station, and transmit a high efficiency short training field (HE-STF) with a same bandwidth as a subsequent data portion, wherein the transmit is to be in accordance with orthogonal frequency division multiple access (OFDMA) and wherein the transmit is within the resource block. A subcarrier allocation for the HE-STF may match a subcarrier allocation for the subsequent data portion. The HE-STF and the subsequent data portion may be transmitted with a same power. A total power of active subcarriers of the HE-STF may be equal to or proportional to a second total of data subcarriers and pilot subcarriers of the subsequent data portion.

Abstract: Embodiments for long training field (LTF) sequences or other types of sequences in uplink multi-user multiple-input multiple-output communications are provided. The LTF sequences can permit channel estimation, including determination of carrier frequency offsets. In some embodiments, an LTF sequence can be formatted and/or conveyed without reliance on pilot tones. In other embodiments, the LTF sequence can rely on pilot tones, where a sequence associated with the pilot tones can include elements that are orthogonal among transmitter station devices that communicate according to MU-MIMO.

Abstract: Embodiments described herein relate generally to a user equipment (“UE”) that is to transmit and receive signals associated with synchronization. The UE may be receive signals associated with synchronization from a plurality of synchronization sources, such as an evolved Node B (“eNB”), a global navigation satellite system (“GNSS”), or another UE. The UE may synchronize to a signal received from a synchronization source based on a priority associated with that synchronization source and/or signal. However, if the UE does not receive any signals associated with synchronization, the UE may generate and transmit a signal that indicates a request for synchronization.
