Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and an evolved Node Bs (“eNBs”) in a plurality of frequency bands. An eNB may transmit cross-carrier, cross-subframe scheduling information to a UE in a licensed frequency band. In response reception of the scheduling information, the UE may sense a wireless transmission medium to determine if the medium is idle. If the medium is idle, the UE may generate and transmit a request to reserve the medium in the unlicensed frequency band (e.g., a Clear-to-Send message). The eNB may transmit downlink data to the UE in the unlicensed frequency band. Other embodiments may be described and/or claimed.

Abstract: Embodiments of an access point (AP), a user station (STA), and a method for range estimation in a wireless network are generally described herein. For example, the AP may encode a common information field of a first trigger frame to include a trigger frame type configured to check the readiness of associated and unassociated STAs. The AP may transmit the first trigger frame to STAs and receive feedback from the STAs. The AP may further encode, based on the feedback, a common information field of a second trigger frame to include one of: a trigger frame type that solicits negotiation packets from associated and unassociated STAs using an association identifier (AID) and a pre-AID; or a trigger frame type that solicits channel sounding packets from associated and unassociated STAs using an AID and a pre-AID. The AP may further transmit the second trigger frame to the STAs.

Abstract: This disclosure describes systems, methods, and devices related to a bidirectional location measurement report (LMR) feedback. A responding device may determine a first location measurement report (LMR) feedback type of an initiating device. The responding device may determine a second LMR feedback type of the responding device. The responding device may determine a common availability window, defined by a common start time and a common end time, for an exchange of a first LMR and a second LMR, wherein the common availability window is based on the first LMR feedback type and on the second LMR feedback type. The responding device may cause to send the first LMR to the initiating device during the common availability window. The responding device may identify the second LMR received from the initiating device during the common availability window.

Abstract: Methods, apparatus, and computer-readable media are described to encode a trigger frame for a second station (STA2). A first sounding frame for the STA2 is generated. The first timestamp is associated with a transmission of the first sounding frame. A second sounding frame from the STA2 based upon the first sounding frame is decoded. The second sounding frame includes a holding time indication associated with a second timestamp and a third timestamp. A fourth timestamp is associated with receiving the second sound frame. The holding time indication is protected. A round-trip time is calculated based upon the first timestamp, the holding time indication, and the fourth timestamp.
