Waveform for synchronization and beam management of a secondary cell

A network node for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• transmit, to a user equipment (UE), synchronization reference signals (RSs) of a primary cell (PCell) of a wireless network, the RSs of the primary cell configured to support synchronization with the PCell;
• transmit an indication to activate a secondary cell (SCell) of the wireless network;
• transmit an RS of the SCell, the RS of the SCell being associated with one or more of:
• a reduced candidate beams list for an initial beam search, relative to a candidate beams list for initial beam searches without synchronization with the PCell, or
• a reduced time domain range for transmitting the RS of the SCell;
• and
• communicate via the secondary cell based at least in part on the synchronization with the secondary cell.

A method of wireless communication performed by a user equipment (UE), comprising:

• obtaining synchronization with a primary cell (PCell) of a wireless network;
• receiving an indication to activate a secondary cell (SCell) of the wireless network;
• receiving a reference signal (RS) of the SCell, reception of the RS of the SCell, based at least in part on obtaining synchronization with the PCell, comprising one or more of:
• using a reduced candidate beams list for an initial beam search, relative to a candidate beams list for initial beam searches without synchronization with the PCell;
• or
• using a reduced time domain range for receiving the RS of the SCell;
• obtaining synchronization with the SCell based at least in part on the RS of the SCell;
• identifying a beam pair for communicating via the SCell based at least in part on the RS of the SCell;
• and
• communicating via the SCell based at least in part on the synchronization with the SCell and using the beam pair.
