Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform calibration of a transceiver chain to maintain or improve operation of a device or comply with legal or protocol requirements. The UE may receive one or more wireless signals indicating a first set of resources where the first device is scheduled to transmit or receive communications. The UE may calibrate a wireless transceiver chain of the first device in a second set of resources. The second set of resources excludes the first set of resources and includes at least a portion of a third set of resources. The third set of resources are resource in which the first device has an option to transmit or receive communications based on a protocol configuration.

Abstract: Methods, systems, and devices for wireless communications are described that provide for refinement of receive beam beamforming parameters at a user equipment (UE). A UE may transmit two or more signals in an uplink transmission that have different beamforming parameters. A base station receiving the uplink transmission may measure the two or more signals, and identify a first signal of the two or more signals based at least in part on the measuring. The base station may inform the UE of the identified first signal, which the UE may use to set receive beam beamforming parameters for one or more subsequent downlink transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support multi-band operation. Different frequency bands may experience different communication characteristics (e.g., frequency-dependent fading), which may result in undesirable interference patterns and/or coverage gaps. The described techniques provide for discovery procedures for multi-band operation. The discovery procedures may allow for improved throughput, improved energy efficiency, reduced signaling overhead, as well as other benefits for a wireless communications system. Generally, the described techniques provide for efficient discovery reference signal (DRS) transmissions over multiple frequency bands. The timing of the DRS transmissions across the different bands may be related or the DRS transmission timing for each band may be determined independently.

Abstract: Disclosed embodiments facilitate efficient positioning of stations (STAs) on wireless networks. A method on an Access Point may determine, at a first time, availability of the Access Point (AP) for positioning; and transmit, based at least in part, on the determination, information indicative of the AP's availability for positioning. The transmitted information may comprise one or more of: STA-AP location determination availability, STA-AP location determination capability, whether AP-AP positioning is being performed; and/or the next scheduled AP-AP ranging session. In some embodiments, a STA may initiate location determination to determine a location of the STA based, at least in part, on indications of availability for positioning for one or more Access Points (APs) communicatively coupled to the STA. Each indication of availability may correspond to a distinct AP of the one or more APs, and the location determination may comprise either: STA-AP location determination, or passive location determination.

Abstract: This disclosure provides systems, methods and apparatuses for detecting a presence of long training fields (LTFs) in packet extensions of high-efficiency (HE) packets. An apparatus requests a length of packet extensions to be used for a ranging operation. The apparatus receives an HE packet including a packet extension containing a selected number of LTFs based at least in part on the requested packet extension length. The apparatus performs the ranging operation based on a determination that the packet extension contains LTFs. In some aspects, the apparatus detects a presence of LTFs in the packet extension based on a bit provided in the HE packet. In some other aspects, the apparatus detects a presence of LTFs in the packet extension by extracting sequences from the packet extension.
