1. A method of communications, comprising:
transmitting, by a network node, a synchronization signal block (SSB) to a user equipment (UE), the synchronization signal block (SSB) comprising a plurality of beams;
transmitting, by the network node, a panel activation request to the user equipment (UE); and
receiving, by the network node, in response to the transmitting of the synchronization signal block (SSB) and the panel activation request:
a first transmission of a physical random access channel (PRACH) using a first physical random access channel (PRACH) resource of a first set of physical random access channel (PRACH) resources, the first set of physical random access channel (PRACH) resources configured for the plurality of the beams associated with the SSB,
a second transmission of the physical random access channel (PRACH) using a second physical random access channel (PRACH) resource of a second set of physical random access channel (PRACH) resources, the second transmission comprising a panel activation message and the second set of physical random access channel (PRACH) resources configured for indicating one or more panels activated at the user equipment (UE), and
wherein the first transmission and the second transmission are received using a same receive (Rx) beam at the network node, the second transmission directly following the first transmission on the receive (Rx) beam, the first transmission and the second transmission being received without a transmitting of a signal to the user equipment (UE) in between the receiving of the first transmission and the receiving of the second transmission.
