    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for determining a helper UE group to facilitate communications with a target using sidelinks. A helper UE may determine a sidelink channel correlation with at least one other UE, report to a base station channel diversity information, UE state information, UE traffic pattern information, sidelink channel measurements, and the determined sidelink channel correlation; and receive an indication from the gNB if the UE is a member of a helper UE group. A base station may transmit a control message to at least one UE; receive a report comprising sidelink channel correlation information, sidelink channel diversity information, and UE state information, from each of the at least one UE, in response to transmitting the control message; and determine a helper UE group based on the received report.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration information from a base station that indicates a set of resources for the UE to establish sidelink communications with another UE in a wireless network. The UE may transmit a first set of reference signals using a first set of beams to determine a set of neighboring candidate UEs for a sidelink connection. The UE may then transmit a second set of reference signals on a second set of beams to the neighboring candidate UEs, and may select a second UE located in the determined neighboring set using various beam scanning procedures. The UE may identify a transmit beam associated with the second UE, and may establish the sidelink connection using the identified transmit beam.

    Abstract: Wireless communications systems and methods related to coordinated beam refinement and coordinated beam failure recovery (BFR) in a wireless communication network are provided. A first wireless communication device communicates, with a second wireless communication device of a group of wireless communication devices, a communication signal using a first beam characteristic. The first wireless communication device receives, from the second wireless communication device, at least one of beam feedback information or a beam change request. The first wireless communication device transmits, to the group of wireless communication devices in response to the at least one of the beam feedback information or the beam change request, a beam configuration indicating a second beam characteristic to be used by the group of wireless communication devices for communicating with the first wireless communication device, the second beam characteristic being different from the first beam characteristic.

    Abstract: Methods, systems, and devices for wireless communications are described that provide beam determination in beamformed wireless communications. A base station may transmit multiple repetitions of control information for a subsequent scheduled transmission. A user equipment (UE) may receive one of the multiple repetitions, determine the control information, and adjust beamforming parameters for the scheduled transmission. The UE may have a scheduling threshold that corresponds to a time needed for the UE to adjust beamforming parameters for the scheduled transmission, and the UE may identify the beamforming parameters for the scheduled transmission from any one of the multiple repetitions of control information, which may be transmitted using different downlink transmission beams, before or after the scheduling threshold, or combinations thereof.

    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.
