Beam correlation across frequency bands

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

• transmitting, to a user equipment (UE), a configuration indicating a mapping between a plurality of beam identifiers and a plurality of angle coverage ranges for each beam identifier of the plurality of beam identifiers, wherein each angle coverage range of the plurality of angle coverage ranges corresponds to an operating frequency of a plurality of operating frequencies within at least one frequency band;
• transmitting a first signal at a first operating frequency of the plurality of operating frequencies using a first beam identifier of the plurality of beam identifiers, the first signal transmitted within a first angle coverage range of the plurality of angle coverage ranges that corresponds to the first operating frequency in accordance with the configuration;
• and
• transmitting a second signal at a second operating frequency of the plurality of operating frequencies using a second beam identifier of the plurality of beam identifiers, the second signal transmitted within a second angle coverage range of the plurality of angle coverage ranges that corresponds to the second operating frequency in accordance with the configuration.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station, a configuration indicating a mapping between a plurality of beam identifiers and a plurality of angle coverage ranges for each beam identifier of the plurality of beam identifiers, wherein each angle coverage range of the plurality of angle coverage ranges corresponds to an operating frequency of a plurality of operating frequencies within at least one frequency band;
• determine a frequency switch from a first operating frequency of the plurality of operating frequencies to a second operating frequency of the plurality of operating frequencies;
• and
• select a second beam identifier of the plurality of beam identifiers based at least in part on the frequency switch and the mapping, the selected second beam identifier corresponding to the second operating frequency and a second angle coverage range based on the mapping.
