Abstract: Certain aspects of the present disclosure provide techniques for radar detection by an apparatus. In certain aspects a method for radar detection by an apparatus includes selecting one or more radar transmission parameters based on a reference time, wherein the reference time is common to at least a group of vehicles. The method further includes performing radar detection using the selected radar transmission parameters and the reference time.

Abstract: Methods, systems, and devices for radar signaling s are described. In some systems, devices may select radar parameters (e.g., frequency modulated continuous wave waveform parameters) to support coexistence for multiple radar sources in the system. To reduce mutual interference between radar waveforms in a system, a user equipment may detect interference from at least one interference source (e.g., another device transmitting a radar waveform) and may select waveform parameters for transmission of a radar waveform based on the detected interference. For example, the user equipment may determine slopes, frequency offsets, codewords, or a combination thereof used by nearby devices in the system (e.g., per chirp or for a waveform) and may select waveform parameters that result in low mutual interference with the determined slopes, frequency offsets, codewords, or combination thereof. The user equipment may transmit the radar waveform according to the selected waveform parameters.

Abstract: Wireless communications systems and methods related to mitigating maximum permissible exposure (MPE) constraints based on user equipment (UE) feedback are provided. A first wireless communication device transmits, to a second wireless communication device, a plurality of reports, each report indicating an allowable transmission power level at the first wireless communication device satisfying an MPE parameter. The first wireless communication device receives, from the second wireless communication device, a first configuration based on an MPE profile associated with the first wireless communication device in response to the plurality of reports. The first wireless communication device transmits, to the second wireless communication device, a first communication signal over a first beam based on the first configuration.

Abstract: Methods, systems, and devices for wireless communications are described for phase error estimation and correction with sub-symbol resolution. A transmitting device may precode symbols (e.g., phase tracking reference signal (PT-RS) symbols) using a discrete Fourier transform (DFT). The transmitting device may map the DFT-precoded symbols to sets of adjacent subcarriers of a wireless signal, and may map other symbols to other subcarriers of the wireless signal. A receiving device may receive the wireless signal and may compare time domain representations of the DFT-precoded symbols with time domain representations of known reference symbols. The receiving device may estimate a phase error with sub-symbol resolution in the time domain based at least in part on the comparison, and may apply a phase correction in either the time or frequency domain to the other symbols.

Abstract: Methods, systems, and devices for wireless communications are described. A milimeter wave (mmW) user equipment (UE) may initiate handover from one base station to another. The handover procedure may not include random access channel (RACH) transmissions, and thus may be a localized RACH-less handover. The UE may initiate handover to a new base station based on the relative location of the UE and the new base station, some predetermined time, a handover configuration identifying a beam associated with the second base station or based on the characteristics of the signals from each base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink transmission to a base station is to occur in accordance with an uplink timing advance value representing an amount of time that the uplink transmission takes from transmission at the UE to reception at the base station. The UE may perform an autonomous open-loop adjustment to the uplink timing advance value. The UE may transmit the uplink transmission to the base station in accordance with the adjusted uplink timing advance value. The base station may transmit an indication of a set of uplink timing advance values for a UE to use for uplink transmissions, each of the set of uplink timing advance values representing an amount of time that an uplink transmission is expected to take from transmission at the UE to reception at the base station.

Abstract: High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.
