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: To facilitate more flexible blind detection, a UE may be configured receive PDCCH in a set of consecutive slots, the set of consecutive slots comprising at least two slots. The UE may be further configured to perform blind detection on each PDCCH received in the set of consecutive slots based on a first PDCCH blind detection limit and a second PDCCH blind detection limit, the first PDCCH blind detection limit being a single-slot limit, the second PDCCH blind detection limit being a multi-slot limit.

Abstract: Aspects relate to configuring a delay between a downlink control channel and a downlink/uplink. For example, the base station determines first search spaces indicating potential locations for a first downlink control channel and/or second search spaces indicating potential locations for a second downlink control channel. The base station configures and transmits first delays and/or second delays. Each first delay indicates a respective time delay between a resource location of the first downlink control channel and a resource location of a downlink data associated with the first downlink control channel and is configured for a respective first search space of the first search spaces. Each second delay indicates a respective time delay between a resource location of the second downlink control channel and a resource location of an uplink data associated with the second downlink control channel and is configured for a respective second search space of the second search spaces.

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: A scheduled entity measures a power level of a demodulation reference signal (DMRS) prior to blind decoding a physical downlink control channel (PDCCH) candidate associated with the DMRS. The scheduled entity performs blind decoding of the PDCCH candidate if the power level is above a predetermined threshold or foregoes blind decoding if the power level is below the predetermined threshold. A scheduling entity transmits a blind decoding configuration setting to the scheduled entity. The scheduling entity enables, via the blind decoding configuration setting, measurement, at the scheduled entity, of power levels of a plurality of DMRSs prior to blind decoding a plurality of respective PDCCH candidates associated with the plurality of DMRSs. Only PDCCH candidates associated with DMRSs having power levels that are above the predetermined threshold are blind decoded. A predetermined number of PDCCH candidates are scheduled for blind decoding. Blind decoding stops when the predetermined number is reached.

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.
