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).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability of the UE to support a restricted bandwidth for data signaling. The UE may receive an indication of a bandwidth part for control signaling and an indication of a set of frequency domain resources for the data signaling. The set of frequency domain resources may correspond to a subset of the bandwidth part in accordance with the restricted bandwidth. The UE may communicate the control signaling over the bandwidth part and data signaling over the set of frequency domain resources. In some cases, the bandwidth restriction may correspond to a bandwidth size for the set of frequency domain resources or a number of resource blocks in the set of frequency domain resources.

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: 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: Certain aspects of the present disclosure provide techniques for providing direct current locations of bandwidth parts (BWPs) in a BWP hopping pattern. Certain aspects relate to a method for wireless communication by a user equipment (UE). In some examples, the UE may receive, from a base station (BS), a request for uplink direct current location information of the UE, wherein the UE is configured to transmit to the BS on an uplink according to a frequency hopping pattern for hopping between a plurality of uplink bandwidth parts corresponding to different frequency bandwidths. In some examples, the UE may transmit, to the BS, at least one uplink direct current location applicable to the plurality of uplink bandwidth parts. In some examples, the UE may transmit, to the BS, on the uplink according to the frequency hopping pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate measurement gap information to a base station. For example, a UE may receive signaling configuring hopping patterns for multiple bandwidth parts (BWPs). Each BWP may include resource blocks having a bandwidth that is less than a threshold bandwidth support by the UE. The UE may transmit control signaling indicating measurement gap information for frequency spectrum bands, and the control signaling may indicate whether a measurement gap is applicable for measurements. The indication may be based on hopping patterns and a frequency-domain location of signals to be measured. The UE may determine a measurement gap pattern for an active BWP based on an association between the measurement gap pattern and the active BWP, or between the measurement gap pattern and a hopping pattern. The UE may perform measurements on signals based on the measurement gap pattern.

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.
