Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a bandwidth part (BWP) hopping configuration indicating a set of hops for a BWP of the UE. The UE may identify a radio link failure (RLF) during a time period configured by the set of hops. The UE may disable the BWP hopping configuration based at least in part on identifying the RLF. The UE may initiate a random access procedure on a BWP that is associated with the random access procedure. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing a bandwidth of a user equipment (UE). The UE has a narrower bandwidth part (NBWP) that follows a NBWP hopping pattern and allows the UE to hop frequency over time within a larger bandwidth. The UE receives a configuration of one or more NBWP hopping patterns for one or more configured NBWPs, each configured NBWP having a bandwidth less than or equal to a maximum configurable bandwidth of a bandwidth part. The UE determines an active NBWP hopping pattern for an active NBWP of the one or more configured NBWPs. The UE communicates on frequency domain resources for a frequency domain hop indicated by the active NBWP hopping pattern applied to the active NBWP. The UE may receive an indication of whether to switch the active NBWP hopping pattern.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for control signal transmission. One aspect provides a method for wireless communication by a user equipment (UE). The method generally includes receiving, from a base station (BS), a message indicating multiple configurations for physical uplink control channel (PUCCH) transmission; selecting, from a sequence database, a sequence to be used for the transmission of a PUCCH in accordance with one of the multiple configurations indicated by the message from the base station; and transmitting the PUCCH using the selected sequence.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical downlink control channel (PDCCH) scheduling a physical downlink shared channel (PDSCH). The UE may transmit a physical uplink control channel (PUCCH) based on a PUCCH repetition factor, wherein the PUCCH repetition factor is indicated by a location of a control channel element (CCE) of the PDCCH, a PUCCH resource indicator (PRI) bitfield of the PDCCH, and at least one of: one or more parameters of the PDCCH, or one or more parameters of the PDSCH. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may receive, from a base station, a physical downlink control channel (PDCCH) indicating a configuration for one or more of demodulation reference signal (DMRS) bundling that is to be used for channel estimation by the base station for a first group of physical uplink control channels (PUCCHs) or frequency hopping for a second group of PUCCHs. The apparatus may transmit, to the base station, one or more PUCCHs based at least in part on the configuration. Numerous other aspects are described.

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, an indication that indicates a blockage event as a cause for a change in one or more of rank information or channel quality information, wherein the blockage event is associated with a differential signal power between a first polarization and a second polarization. The UE may receive, from the base station, a transmission based at least in part on the indication that indicates the blockage event as the cause for the change in one or more of the rank information or the channel quality information. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for narrowband random access channel (RACH) occasions. A method that may be performed by a user equipment (UE) includes receiving, from a network entity, a configuration indicating one or more frequency resources for a RACH procedure, wherein the one or more frequency resources are arranged within a set of frequency resources allocated for RACH transmissions. The method further includes performing the RACH procedure based at least in part on the configuration.

Abstract: A base station may select whether to configure one or more second RACH reference slots associated with a plurality of first RACH reference slots in a RACH configuration period. The one or more second RACH reference slots may be new RACH reference slots, and the plurality of first RACH reference slots may be previously existing RACH reference slots. The base station may identify, upon selecting to configure the one or more second RACH reference slots, a RACH reference slot configuration including the one or more second RACH reference slots associated with the plurality of first RACH reference slots in the RACH configuration period. The base station may transmit, to at least one UE, an indication of the RACH reference slot configuration including the one or more second RACH reference slots associated with the plurality of first RACH reference slots.
