Abstract: Apparatus, methods, and computer-readable media for facilitating per bandwidth part TCI state or spatial relation are disclosed herein. For example, aspects disclosed herein provide techniques for enabling a UE (e.g., a reduced capability UE) to associate at least one of a TCI state or a spatial relation with respective hopping regions. An example method for wireless communication at a UE includes determining, while communicating using a first frequency range comprising a first set of frequency hops, at least one of a TCI state or a spatial relation for communicating using a second frequency range comprising a second set of frequency hops. The example method also includes communicating, after switching communication from the first frequency range to the second frequency range, using the second frequency range based on the determined at least one of the TCI state or the spatial relation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information indicating at least one of a power amplifier sharing configuration or a phase noise sharing configuration for a plurality of layers of a single-carrier communication. The UE may receive, from the base station, a phase tracking reference signal (PTRS) configuration for the plurality of layers based at least in part on at least one of the power amplifier sharing configuration or the phase noise sharing configuration. The UE may perform the single-carrier communication in accordance with the PTRS configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit sounding reference signals (SRSs) on a plurality of beams to a base station using a set of SRS resources indicated by the base station. The UE may receive, from the base station, an SRS resource indicator indicating one or more SRS resources of the set of SRS resources and determine a combined transmit beam from the plurality of beams based at least in part on the SRS resource indicator. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive, while connected to a first cell associated with a physical cell identifier (PCI) and a first cell global identifier (CGI), a message that includes an indication to connect to a second cell, associated with the PCI and a second CGI, responsive to detecting the second CGI in a system information message associated with the PCI. The wireless node may connect to the second cell based at least in part on detecting the second CGI in the system information message associated with the PCI. 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 receive an indication of a search space configuration that identifies one or more parameters associated with demodulation reference signals (DMRSs) for a physical downlink control channel (PDCCH) communication. The UE may decode a PDCCH candidate associated with the PDCCH communication, based at least in part on the one or more parameters associated with the DMRSs, wherein the PDCCH candidate is aggregated over one or more PDCCH monitoring occasions. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for blind decoding and channel estimation (BD/CE) limitations and configuration of new radio (NR) physical downlink control channel (PDCCH) repetition. A method that may be performed by a user equipment (UE) includes receiving, from a base station, an indication of at least one blind detection limit for detecting a control channel from a set of blind detection limits and monitoring for the control channel based on the received indication of the at least one blind detection limit for detecting the control channel.

Abstract: Aspects of disclosure relate to a network node for changing a physical cell identifier (PCI). The network node transmits a first signal based on a first PCI during a first synchronization signal block (SSB) occasion, transmits a second signal based on the first PCI during a second SSB occasion, and transitions from the first PCI to a second PCI. During a transition period, the network node transmits the first signal based on the second PCI during the first SSB occasion, and continues to transmit the second signal based on the first PCI during the second SSB occasion. After an end of the transition period, the network node continues to transmit the first signal based on the second PCI during the first SSB occasion, and ceases transmission of the second signal based on the first PCI during the second SSB occasion. Other aspects and features are also claimed and described.

Abstract: To provide a more robust connection and better coverage, a UE may be configured to receive an SFN PDSCH through a plurality of beams from a plurality of TRPs including a first TRP and a second TRP, the plurality of beams being based on configured DL TCI states. The UE may be further configured to transmit a same PUSCH through each of the plurality of beams. In addition, the same PUSCH may be transmitted through a first beam of the plurality of beams n times, and transmitted through a second bream of the plurality of beams m times, where n and m are integers greater than or equal to one.
