Beam management for bandwidth part not including synchronization signal block

A method for wireless communication at a user equipment (UE), comprising:

• communicating with a base station over a first bandwidth part of a carrier;
• receiving a signal configuring a set of periodic channel state information reference signals (CSI-RSs) for the first bandwidth part of the carrier, wherein each periodic CSI-RS of the set of periodic CSI-RSs is spatially quasi-collocated with a synchronization signal in a second bandwidth part;
• measuring the set of periodic CSI-RSs in the first bandwidth part based at least in part on the set of periodic CSI-RSs being spatially quasi-collocated with the synchronization signal in the second bandwidth part;
• and
• determining a beam for communicating with the base station over the first bandwidth part based at least in part on the measuring.

A method for wireless communication at a base station, comprising:

• communicating with a user equipment (UE) over a first bandwidth part of a carrier;
• transmitting a beam failure recovery (BFR) configuration signal configuring a set of periodic channel state information reference signals (CSI-RSs) in the first bandwidth part and a set of synchronization signals in a second bandwidth part, wherein the set of periodic CSI-RSs in the first bandwidth part are spatially separate from the set of synchronization signals in the second bandwidth part;
• transmitting the set of periodic CSI-RSs in the first bandwidth part and the set of synchronization signals in the second bandwidth part;
• receiving a measurement report from the UE indicating a beam index associated with a periodic CSI-RSI of the set of CSI-RSs;
• and
• setting a beam for communicating with the UE over the first bandwidth part based at least in part on the measurement report.
