Abstract: Methods, systems, and devices for wireless communications are described. The network may configure a user equipment (UE) with measurement objects indicating the synchronization signal blocks (SSB)s to be measured for neighbor cells. A UE may receive control signaling from the network indicating a switch from a first bandwidth part (BWP) to a second BWP. The first BWP may be associated with a first cell measurement type for neighbor cells (e.g., inter-frequency or intra-frequency) and a first reference SSB. The second BWP may be associated with a second, different, cell measurement type for neighbor cells and a second, different, reference SSB. After the BWP switch, the UE may perform measurements on SSBs associated with neighbor cells based on the second cell measurement type.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication that the UE is to perform radio resource management (RRM) measurements at a first periodicity. The UE may identify an RRM measurement relaxation grouping to which the UE belongs based on at least one of a mobility of the UE or a location of the UE within a cell, such as whether the UE is near a cell-edge, or whether the UE is stationary or moving in accordance with low-mobility, or a combination thereof. The UE may determine a first relaxation parameter from a plurality of relaxation parameters based on measurement relaxation criterion associated with the cell, where the plurality of relaxation parameters may be associated with the RRM measurement relaxation grouping. The UE may perform the RRM measurements at a second periodicity that is based on the first relaxation parameter.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a grant scheduling repetition-based system information block transmissions for the UE, the grant indicating a mapping configuration identifying time-frequency resources for a second repetition of a system information block transmission relative to a first repetition of the system information block transmission. The UE may receive, in a first subset bandwidth of a system bandwidth, the first repetition of the system information block transmission according to the grant. The UE may receive, in a second subset bandwidth of the system bandwidth, the second repetition of the system information block transmission according to the grant and based at least in part on the mapping configuration.

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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for measurement without gaps for narrow bandwidth part (BWP) hopping. A user equipment (UE) may measure one or more synchronization signal blocks (SSBs) while performing BWP hopping according to a hopping pattern. The UE may receive data and measure an SSB in a same frequency hop during a same measurement window without a gap. A base station (BS) may transmit a control message to the UE to configure an active BWP for the UE, a set of measurement windows, a hopping pattern, and a set of SSBs that occur within a set of frequency hops to support the measurement without gaps. The active BWP may be defined for measurement purposes to reduce ambiguity. The control message may support alignment of a measurement window with an active frequency hop to support measurement without gaps.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with a frequency hopping pattern for communication between the UE and a base station, and also may be configured with a measurement gap pattern for measurement of one or more reference signals from one or more neighboring base stations. One or more switching timings of a set of switching timings of the frequency hopping pattern may be aligned with a reference point associated with the measurement gap pattern, which may provide aligned switching gaps in the frequency hopping pattern and the measurement gap pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message that indicates a first initial uplink bandwidth part for use by the UE in communications with a network entity, the message also indicating a plurality of random access occasions, at least one of the plurality of random access occasions being in frequency resources that are outside of the first initial uplink bandwidth part. The UE may select a random access occasion of the plurality of random access occasions for transmission of a random access preamble from the UE to the network entity. The UE may transmit, as part of a random access procedure, the random access preamble within the random access occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A synchronization signal block (SSB) may be dynamically scheduled within an operating bandwidth of a user equipment (UE), where the operating bandwidth of the UE is outside of a frequency resource in which a cell defining SSB (CD-SSB) is scheduled. For example, a UE may operate in a reduced capability mode or an enhanced reduced capability mode where the UE may operate in a narrower bandwidth than the serving cell bandwidth. Control signaling may dynamically configure an SSB for the UE within the operating bandwidth of the UE. The UE may monitor for the non-cell defining SSB (NCD-SSB) and skip monitoring for the CD-SSB based on the dynamically configured NCD-SSB. For example, a reduced capability UE or an enhanced reduced capability UE may monitor for the NCD-SSB without performing RF retuning between receiving the control signaling and monitoring for the NCD-SSB.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), such as a UE with reduced capabilities, may switch from a first bandwidth part (BWP) to a second BWP to receive system information for a carrier that includes the first and second BWPs. The UE may switch to the second BWP to receive system information based on a trigger (e.g., control signaling or an expiration of a timer) and then switch back to the first BWP without additional signaling to continue operation. In some examples, the UE may receive additional signaling (e.g., data, control signaling, reference signals) in the second BWP. In some examples, a BWP switching duration may include additional time to process the system information received in the second BWP, for example if the system information includes instructions to switch to a third BWP (e.g., rather than returning to the first BWP).
