Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a measurement configuration, from a second wireless device, to support full-duplex operation using a shared resource. The first wireless device may transmit, via the shared resource, a first signal via a first transmission beam using a first antenna array of the first wireless device. The first wireless device may monitor, in accordance with the measurement configuration, the shared resource using a first receive beam via a second antenna array of the first wireless device. The first wireless device may then transmit a measurement report to a second wireless device based on the monitoring. The second wireless device may transmit, to the first wireless device, a duplexing configuration configuring the full-duplex operation of the first wireless device based on the measurement report.

Abstract: Various aspects include methods for beam sweep configuration of a millimeter wave (MMW) repeater in a fifth generation (5G) network during random access channel (RACH) procedures. Various embodiments include receiving an RACH 1 message relayed by an MMW repeater, determining a beam sweep schedule for use by the MMW repeater in relaying a random access response (RAR) message in response to the RACH 1 message, wherein the beam sweep schedule indicates a series of RAR messages to be sent successively and a different transmit (TX) beam sweep configuration to be used by the MMW repeater for each of the series of RAR messages, generating an RAR control message indicating the beam sweep schedule, sending, by the processor of the network device, the RAR control message to the MMW repeater, and sending the series of RAR messages to the MMW repeater.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a collective antenna array that includes both a downlink antenna array and an uplink antenna array for communications with a second wireless device. Accordingly, the first wireless device and the second wireless device may perform a beam training procedure on the collective antenna array, and the first wireless device may then use beam weights identified for the collective antenna array as the beam weights for the specific downlink antenna array and the uplink antenna array. For example, the first wireless device and the second wireless device may perform downlink beam training to obtain a best downlink receive beam to use and then determine an uplink transmit beam to use based on the downlink receive beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

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 wireless communications are described. A wireless device may dynamically select subsets of antenna elements within an array based on power consumption and link performance and/or a configuration of components at the wireless device. For example, a wireless device may identify an antenna array having multiple antenna elements, and the wireless device may select respective subsets of antenna elements (e.g., subarrays) for uplink and downlink transmissions. In such cases, the selection may be based on a tradeoff of power consumption at the device and link performance. Additionally or alternatively, the selection may be based on a configuration and/or constraints on a number of radio frequency (RF) components of the wireless device. The wireless device may communicate based on the dynamic selection of different subsets of antenna elements of an array for uplink and downlink communications.

Abstract: Certain aspects of the present disclosure provide techniques for signaling information regarding beams used for data and control transmissions to a UE. For example, a method for wireless communications by a user equipment (UE), may generally include signaling information to a base station (BS) that the UE is seeking recovery of a beamformed link between the BS and the UE, and participating in recovery of the beamformed link in accordance with the information. A method for wireless communications by a base station (BS), may generally include receiving information from a user equipment (UE) that the UE is seeking recovery of a beamformed link between the BS and the UE, and participating in recovery of the beamformed link in accordance with the information.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may include multiple antenna arrays used to support wireless communications. The antenna arrays may be located at different parts of the UE and may allow the UE to flexibly perform beamforming communications. The antenna arrays maybe configured as antenna sets, and the size of each antenna set may vary based on the configuration of the UE. For example, a UE may include a foldable display having multiple foldable display units, and the communication parameters used for transmission and reception of signals via the antenna arrays may depend on the configuration of the foldable display units. In some aspects, a state of the foldable display units or the arrangement of the antenna arrays relative to one another may be used to configure and perform beamforming communications between the UE and a base station.
