Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for selecting a PRACH occasion (RO) based on downlink quality, access congestion, latency (e.g., time to next available RO), beam correspondence, random access in previous transmissions, or combinations of these factors. The user equipment (UE) may detect access congestion of synchronization signal blocks (SSBs) and select the less congested SSB in the RO selection. The UE may detect the access congestion by receiving a back-off indicator from the base station, detecting a contention resolution failure, or the number or media access control (MAC) subheaders in a random access response. In some cases, the ROs associated with different SSBs have different latencies and the UE may select the earliest available RO.

Abstract: Techniques and devices for wireless communication are described. A communication device may identify a set of beam level selection parameters. The set of beam level selection parameters may include traffic information, channel information, application information, or any combination thereof. The communication device may select, based on the identified set of beam level selection parameters, a beam level, from a set of beam levels, different from a baseline beam level associated with the wireless communication. The selected beam level may be associated with a number of antenna elements different from a number of antenna elements associated with the baseline beam level. The communication device may perform the wireless communication based on the selected beam level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a minimum slot offset based at least in part on a determination of a minimum wake-up signal (WUS) gap capability associated with the UE, wherein the minimum WUS gap capability corresponds to a capability of the UE to support a WUS gap having a minimum gap size, wherein the minimum slot offset indicates a minimum time period between a physical downlink control channel (PDCCH) occasion and a physical downlink shared channel (PDSCH) occasion scheduled by the PDCCH; and monitor the PDCCH occasion for a downlink grant based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first throughput on a first beam of the UE, wherein the first beam is associated with a first number of antenna elements. The UE may identify an estimated maximum throughput of the UE. The UE may communicate, based at least in part on the first throughput being greater than the estimated maximum throughput, using a second beam, the second beam having a second throughput that is greater than the estimated maximum throughput, and the second beam being associated with a second number of antenna elements lesser than the first number of antenna elements.

The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.
