Claims

A method of wireless communication performed by a user equipment (UE), the method comprising:
receiving information from a base station (BS) identifying a control resource set (CORESET) for one or more shared radio frequency spectrum channels, comprising:
the CORESET includes a plurality of resource blocks based at least in part on resource block granularity associated with the one or more shared radio frequency spectrum channels;
A location of the CORESET within one of the one or more shared radio frequency spectrum channels is indicated relative to a reference frequency associated with the one or more shared radio frequency spectrum channels. , step and
and communicating with the BS using the CORESET.

communicating with the BS based at least in part on the CORESET;
