1. An apparatus for wireless communications at a user equipment (UE), comprising:
one or more memories comprising instructions; and
one or more processors configured to execute the instructions and cause the apparatus to:
receive assistance information, from a network entity, indicating a mapping between beams across different remote radio heads (RRHs), wherein the mapping indicates one or more beams from a first RRH within a same direction as one or more beams from a second RRH, and wherein the assistance information further indicates additional information comprising a distance between projections of adjacent beam peaks; and
use the assistance information to perform beam management when the UE is moving from a coverage area of one RRH to a coverage area of another RRH.
