Abstract: Wireless communications devices with existing peer to peer links transmit, e.g., in accordance with a recurring schedule, quality of service related information corresponding to the existing links. The transmitted quality of service related information is, e.g., information indicating an obtained quality of service for the existing link. In some embodiments, quality of service related information is communicated in one of: a peer discovery signal, a connection ID broadcast signal and a contention resolution signal. A wireless communications device seeking to establish a new peer to peer link receives quality of service related information corresponding to existing links and estimates a quality a service achievable on the new desired potential link based on the received quality of service related information. The wireless communications device decides whether or not to establish the new peer to peer link based on its quality of service estimate.

Abstract: Methods and apparatus for efficiently scheduling links in wireless communications networks are described. Various described methods and apparatus are well suited for use in ad hoc wireless networks in which scheduling decisions are made in a distributed and/or decentralized manner. In some embodiments, the links in a network, e.g., in a peer to peer ad hoc network, are adaptively grouped based on comparable link channel gain. Exemplary signaling used, in some but not necessarily all embodiments, by devices to estimate channel gains include broadcast connection identifier signals and reverse broadcast connection identifier signals. Grouping links into sets based on comparable link channel gain, and selectively ordering the scheduling priorities of the different groups, is used to improve scheduling efficiency, e.g., decrease the likelihood that unnecessary yielding occurs.

Abstract: In some aspects, a system may receive, from a first one-dimensional radar array, first information based at least in part on first reflections associated with an azimuthal plane. The system may further receive, from a second one-dimensional radar array, second information based at least in part on second reflections associated with an elevation plane. Accordingly, the system may detect an object based at least in part on the first information and may determine an elevation associated with the object based at least in part on the second information. Numerous other aspects are described.

Abstract: Methods, systems, computer-readable media, and apparatuses for transmitting and receiving radar signals from a radar source while minimizing interference with other radar sources are presented. A transmit signal comprising a first chirp sequence is generated according to a set of waveform parameters, with least one waveform parameter being varied for one or more chirps in the first chirp sequence. Additionally, each chirp of the first chirp sequence can be phase-modulated. A receive signal comprising a second chirp sequence and corresponding to the transmit signal reflected off an object in a surrounding environment is then sampled to determine one or more attributes of the object. In some embodiments, the attributes include distance and speed values calculated using Discrete Fourier Transforms (DFTs). Other attributes that can be calculated from the receive signal include azimuth angle and elevation angle.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink message to a user equipment (UE). The base station may allocate a receive time window associated with receiving an uplink message from the UE responsive to the downlink message, wherein the receive time window is allocated based at least in part on a maximum propagation round trip time (RTT) associated with UEs within a coverage area of the base station and a frame size of the uplink message. The base station may monitor the receive time window for the uplink message from the UE. The base station may receive the uplink message from the UE during the receive time window.
