Abstract: Methods and apparatus for using code-division multiple access (CDMA) to transmit information via orthogonal frequency-division multiplexing (OFDM) to convey information from user terminals to an access point (AP) in a wireless local area network (WLAN) are provided. By using CDMA to convey information, a propagation delay between an access point (AP) and a user terminal may be determined by the AP, and timing adjustment information based on the delay may be sent to the user terminal. In this manner, subsequent uplink (UL) transmissions from multiple user terminals may be received simultaneously by the AP, despite the multiple user terminals having potentially different propagation delays.

Abstract translation: 提供了使用码分多址（CDMA）通过正交频分复用（OFDM）发送信息以将信息从用户终端传送到无线局域网（WLAN）中的接入点（AP）的方法和装置。 通过使用CDMA来传送信息，可以由AP确定接入点（AP）和用户终端之间的传播延迟，并且可以将基于延迟的定时调整信息发送到用户终端。 以这种方式，尽管多个用户终端具有潜在的不同传播延迟，但是可以由AP同时接收来自多个用户终端的后续上行链路（UL）传输。

Abstract: Monostatic radar (314) with progressive length transmission may be used with half-duplex systems or with full-duplex systems to reduce self-interference. The system transmits a first signal (350) for a first duration (302) and receives a first reflection (324) of the first signal from a first object (316) during a second duration (304). The system transmits a second signal (352) for a third duration (306) longer than the first duration and receives a second reflection (328,330) of the second signal from a second object (318) during a fourth duration (308). The system calculates a position of the first object and the second object based on the first reflection and the second reflection. The first signal, first duration, and second duration are configured to detect reflections from objects (316) within a first distance of the system. The second signal, third duration, and fourth duration are configured to detect reflections from objects (318) between the first distance and a second distance from the system.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a user equipment measures at least a line-of-sight path and a non-line-of-sight path of a first downlink positioning reference signal (DL-PRS) from a first transmission-reception point, measures at least an LOS path and an NLOS path of a second DL-PRS from a second TRP, measures at least an LOS path and an NLOS path of a third DL-PRS from a third TRP, and enables a location of a non-participating target object to be determined based, at least in part, on reference signal time difference (RSTD) measurements between a time of arrival of the LOS path of the first DL-PRS and the ToAs of the NLOS paths of the first, second, and third DL-PRS. In an aspect, the non-participating target object does not participate in determining its own location.

Abstract: Bi-static radio-based object location detection can include determining, by a wireless device, a location of a remote wireless device; obtaining a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determining a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA. In another example, a wireless device includes a wireless transceiver; a non-transitory computer-readable medium; and a processor communicatively coupled to the wireless transceiver and non-transitory computer-readable medium, the processor configured to determine a location of a remote wireless device; obtain a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determine a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an aggregation capability to communicate in parallel over a plurality of wireless links. The wireless device may in some cases broadcast this aggregation capability (e.g., periodically). Additionally or alternatively, the wireless device may transmit the aggregation capability in response to a request received from another wireless device. In some cases, the first wireless device may transmit a request to a second wireless device inquiring about aggregation capabilities of the second wireless device. The second wireless device may respond with its aggregation capabilities (e.g., or may broadcast its aggregation capabilities independently of receiving the response). The wireless devices may establish a multi-link session based at least in part on the indicated aggregation capabilities.

Abstract: Reuse of transmission resources is discussed in which a transmitting node may reuse an entire remaining overlapping basic service set (OBSS) transmission opportunity (TXOP) instead of being limited to reuse based on a per-frame basis. The node may reuse the remaining TXOP if the expected caused interference to other nodes using the resources is below a predetermined threshold. Spatial reuse information may be classified into different mode based on the manner in which the spatial reuse information is obtained by the transmitting node. The manner in which the expected caused interference may be determine may be associated with the particular spatial reuse mode.
