Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an uplink message on an uplink channel associated with a special cell (Spcell) to trigger maximum permissible exposure (MPE) reporting based at least in part on an MPE event. The UE may transmit an MPE medium access control (MAC) control element (MAC-CE) to report the MPE event, wherein the MPE MAC-CE is transmitted on a physical uplink shared channel associated with the Spcell or a secondary cell. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for handling maximum permissible exposure (MPE) events. In some cases, a UE may be configured to detect one or more MPE events and report certain measurements that may help address or avoid the detected MPE event (e.g., adding or removing a cell and/or performing a handover of the UE to another cell).

Abstract: Methods, systems, and devices for wireless communications are described to support determination of an uplink beam for uplink transmissions. A base station may configure a user equipment (UE) with multiple sets of sounding reference signal (SRS) resources that may be used for uplink transmissions from the UE. In some cases, each set of SRS resources may be configured with one associated channel state information reference signal (CSI-RS) resource, and each CSI-RS resource may correspond to an uplink beam. The base station may transmit a downlink control message to the UE, indicating one or more selected SRS resource sets and one or more selected SRS resources within each of the one or more selected SRS resource sets. The UE may transmit an uplink transmission with a beam associated with the indicated SRS resource set.

Abstract: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may receive from a base station (BS), an uplink (UL) scheduling grant indicating subband precoding information and a resource allocation spanning a plurality of subbands. The UE may determine a plurality of subband precoders based on the subband precoding information. Each precoder of the plurality of subband precoders may be associated with a subband of the plurality of subbands. The UE may transmit to the BS, an UL communication signal in the resource allocation using the plurality of subband precoders.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a first configuration for a first sounding reference signal (SRS) set and a second configuration for a second SRS set, the first SRS set to be transmitted using a first group of antennas of the UE and the second SRS set to be transmitted using a second group of antennas of the UE; determine a size of a downlink control information (DCI) field to be included in an uplink DCI communication scheduling a physical uplink shared channel (PUSCH) transmission, the DCI field to indicate a selected SRS set; receive the uplink DCI communication scheduling the PUSCH transmission; and identify the selected SRS set based at least in part on the determined size of the DCI field and information carried in the DCI field. Numerous other aspects are provided.

Abstract: A user equipment (UE) and a network entity may communicate to identify characteristics of a network and/or link that the UE and the network entity can use for communication. However, the UE may lack information indicating which reference signals the UE is to measure and which reference signals the UE can forgo measuring to reduce power consumption, network traffic, or message overhead, among other examples. Some aspects described herein enable a network entity to provide a UE with configuration information to enable the UE to perform event-driven reporting. For example, a network entity may provide a UE with codebook information or location information with which the UE can identify which non-serving cells, of a plurality of available non-serving cells, the UE is to measure and report on. In this way, the network entity and the UE enable reduced power consumption, network traffic, or message overhead.
