Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may determine a beam configuration associated with a set of directional beams of a base station. The beam configuration may include a set of identifiers associated with the set of directional beams. The UE may determine beam position information associated with a coverage area of each directional beam of the set of directional beams based on the beam configuration. Additionally or alternatively, the UE may determine beam classification information associated with the coverage area of each directional beam of the set of directional beams based on the beam configuration. The UE may select a directional beam of the set of directional beams based on the beam position information and the beam classification information, and communicate with the base station using the selected directional beam.

Abstract: Aspects are provided which allow coverage enhancement and support in NTNs for repetition, frequency hopping, and antenna switching during msgA transmissions based on a preamble-to-PO mapping. In one aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with at least one PO for two-step random access, where the PO spans a time interval greater than one slot. In another aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with a plurality of POs for two-step random access. In a further aspect, the base station provides the UE a plurality of configurations each indicating a PO for two-step random access. In an additional aspect, the base station provides the UE a configuration indicating a guard band for a PO for two-step random access, where the guard band is indicated in units of subcarriers spanning less than one PRB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a loss of coherence associated with the UE. The UE may perform at least one adjustment to a transmission parameter or a reception parameter based at least in part on the indication of the loss of coherence. For example, the adjustment to the transmission parameter may include adjusting a transmit power, adjusting a transmit frequency, adapting a transmission time, changing an antenna port, or a combination thereof. Additionally, or alternatively, the adjustment to the reception parameter may include refraining from joint channel estimation across a plurality of slots, adjusting a downscaling parameter or a frequency tuning associated with at least one reception antenna, refraining from blind decoding, or a combination thereof.
