1. A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors coupled to the one or more memories, the one or more processors individually or collectively configured to:
receive, from a network entity and on a primary cell that uses a first subcarrier spacing (SCS), one or more synchronization signal block (SSB) transmissions associated with the first SCS; and
receive, from the network entity and on a secondary cell that uses a second SCS, a plurality of initial access transmissions associated with the second SCS,
wherein a time location of a first initial access transmission, of the plurality of initial access transmissions, that uses a beam is within, or a threshold time before or after, a time location of an SSB transmission, of the one or more SSB transmissions, that uses the beam,
wherein a time gap exists between the first initial access transmission and a second initial access transmission of the plurality of initial access transmissions, wherein the first initial access transmission and the second initial access transmission use consecutive beams according to a beam pattern, and
wherein a starting time of the first initial access transmission that uses a first beam, of the consecutive beams and relative to a time location of a first SSB transmission of the one or more SSB transmissions, is different from a starting time of the second initial access transmission that uses a second beam, of the consecutive beams, relative to a time location of a second SSB transmission of the one or more SSB transmissions.
