Abstract: Disclosed are techniques for receive beam selection for measuring a reference radio frequency (RF) signal. In an aspect, a first node determines a type of measurement to be performed on the reference RF signal, selects a receive beam based on the type of measurement to be performed on the reference RF signal, generates the selected receive beam, receives, from a second node, using the generated receive beam, the reference RF signal transmitted on a wireless channel, and performs one or more measurements on the received reference RF signal according to the type of the measurement to be performed.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include a set of patch antennas in a quasi-linear arrangement along a top linear edge and one or more side linear edges of the UE in addition to a curved part between the two linear edges. For example, a first subset of the patch antennas may be linearly arranged on a first edge along the UE (e.g., the top of the UE), a second subset of the patch antennas may be linearly arranged along a second edge of the UE that is at an angle relative to the first edge (e.g., a side of the UE), and at least one patch antenna may be non-linearly arranged (e.g., quasi-linearly) on a curved line formed between the first subset of the patch antennas and the second subset of the patch antennas.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a first IAB node determining an adjustment to at least one parameter corresponding to a cell coverage of the first IAB node based at least in part on a geographic proximity of a cell relative to the first IAB node. For example, the first IAB node may determine to adjust the parameters based reference signal measurements, signal quality measurements (e.g., received from child nodes or user equipments (UEs)), etc. In another example, the first IAB node may receive an instruction from a central unit (CU) of the IAB network to adjust the at least one parameter. The first access node may transmit an indication of the adjustment to the at least one parameter. For example, the first access node may signal the adjustments to the CU, child IAB nodes, UEs and/or, other IAB nodes.

Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: Aspects of the disclosure relate to methods and apparatus for scheduling traffic between a transmitting device and a receiving device. A transmitting device negotiates with a receiving device to reserve a plurality of slots for communicating data with the receiving device. The transmitting device then sends, at a beginning of one slot of the reserved plurality of slots, a request-to-send (RTS) message indicating a number of slots of the reserved plurality of slots the transmitting device intends to use for transmitting the data. The transmitting device receives, from the receiving device, a clear-to-send (CTS) message in each slot of the number of slots based on the RTS message and transmits the data to the receiving device in each slot of the number of slots upon receiving the CTS message in each slot. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a millimeter wave repeater may communicate with a base station using a first set of antennas and a first beamforming configuration for the first set of antennas, the first beamforming configuration being selected from a beamforming codebook that includes multiple beamforming configurations; and communicate with one or more user equipments (UEs) using a second set of antennas and a second beamforming configuration for the second set of antennas, the second beamforming configuration being a fixed configuration that does not change for different communications between the second set of antennas and the one or more UEs. Numerous other aspects are provided.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a client wireless device may transmit a random access channel (RACH) preamble on a first time domain resource to a recipient such as a host wireless device. The client wireless device may later transmit a second RACH message to the recipient on a second time domain resource after the first time domain resource. The second time domain resource may be defined by a mapping from the first time domain resource. The recipient may transmit a third RACH message establishing a communication session between the host wireless device and the client wireless device. The second RACH message may include one or more of: an identifier of the wireless device; an identifier of the recipient of the second RACH message; a resource configuration for subsequent RACH messages; or timing information.

Abstract: Methods, systems, and devices for wireless communications are described that improve privacy in wireless communications, such as communications by a user equipment (UE), which may in some cases be a vehicle UE. For example, various vehicle-to-everything (V2X) transmissions may be unencrypted, and a vehicle may be expected to periodically change one or more identifiers it uses for various communication services. Privacy may be enhanced, for example, via encryption key roll-over, as well as roll-over of one or more other identifiers associated with a UE that may potentially be used by an observer to track the UE. The UE may transmit a message that includes an updated lower layer identifier (e.g., a layer-2 (L2) identifier) to another UE in a V2X unicast communications link, which may trigger a change in identifiers of a set of identifiers and an updated security context. All or a portion of the message may be encrypted.
