Abstract: Methods, systems, and devices for wireless communication are described. An aerial UE may receive control signaling that indicates a plurality of beam measurement configurations that the aerial UE is to use for beam measurement and reporting associated with a plurality of beams. The aerial UE may monitor a set of beams of the plurality of beams in accordance with a subset of beam measurement configurations of the plurality of beam measurement configurations based on a current time, a current location of the aerial UE, or both, for example. The aerial UE may transmit a measurement report indicating one or more measurements of a subset of beams of the set of beams in accordance with the subset of beam measurement configurations. In some examples, the subset of beam measurement configurations may be associated with an altitude threshold, a three-dimensional zone, or a combination thereof.

Abstract: Wireless communications are described. A user equipment (UE) may receive a configuration message identifying a set of resources available for a plurality of UEs for transmission of feedback indications of multi-cast (or broadcast) transmission to the plurality of UEs, the set of resources comprising a plurality of subsets of resources, each subset of resources being associated with a corresponding channel metric for each UE of the plurality of UEs receiving the multi-cast transmission. The UE may determine that a feedback indication is to be provided in response to the multi-cast transmission. The UE may select, based at least in part on a channel metric of the UE, a first subset of the plurality of subsets of resources to use for transmitting a feedback message including the feedback indication. The UE may transmit the feedback message for the multi-cast transmission using resources within the selected first subset of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message to a base station, the UE capability message including an indication of a UE type, wherein the UE type is associated with at least one of a reduced bandwidth, or a reduced number of antennas, or a combination thereof for the UE. The UE may receive, based at least in part on the UE capability message, a downlink grant for downlink resources for a data transmission in accordance with a resource allocation scheme, wherein the resource allocation scheme is associated with the UE type and a supported bandwidth part of the UE. The UE may monitor a wireless channel based at least in part on the downlink grant. The UE may receive the data transmission based at least in part on the monitoring of the wireless channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more retransmissions of an initial group-common transmission. The UE may receive, in accordance with a first SPS configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first RNTI. The UE may transmit feedback information for the group-common transmission. The UE may then receive a downlink control information (DCI) message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel. The DCI may indicate that either the group-common retransmission is associated with the first RNTI or that the unicast retransmission is associated with a second RNTI that may be different from the first RNTI.

Abstract: In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate configuration, or reconfiguration of PUR allocation for the UE that may be used for uplink transmissions, or release of the PUR allocation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to the base station, a beam recovery request including an indication of a multicast beam, where the beam recovery request is transmitted based at least in part on a unicast uplink grant, and where the unicast uplink grant comprises a set of uplink resources for a multicast beam recovery procedure based at least in part on a failure of the multicast beam associated with multicast communications between the UE and the base station. The UE may receive, from the base station in response to the beam recovery request, a response message including an indication of a second uplink grant, an indication of a second beam for communications between the UE and the base station, or both. The UE may transmit a first uplink transmission via the second uplink grant, the second beam, or both.
