1. A method for wireless communications by a user equipment (UE), comprising:
detecting an occurrence of a threshold number of beam failures for a connection between the UE and a first cell in a set of cells;
identifying a candidate beam for restoring the connection between the UE and the first cell in the set of cells in response to detecting the occurrence of the threshold number of beam failures;
transmitting, to one or more second cells in the set of cells other than the first cell, a beam failure recovery (BFR) request including an identification of the candidate beam;
receiving, from the one or more second cells in the set of cells other than the first cell, a BFR response in response to transmitting the BFR request, wherein the BFR response is received according to a restriction rule, wherein the restriction rule allows the BFR response to be received from any cell in the set of cells other than the first cell, and wherein the restriction rule further defines a gap between receipt of the BFR response and resuming communications with the set of cells based on a numerology of one of: the cell from which the BFR response is received or a failed cell on which a beam failure was detected; and
resuming communications with the set of cells based on the BFR response.
