Multiple beam operations in wireless communication systems

A user equipment (UE) comprising:

• a processor;
• and
• a transceiver configured to receive or transmit signals, from a base station (BS) or to the BS, based on an operation mode comprising a first operation mode corresponding to a first value or a second operation mode corresponding to a second value, wherein the operation mode is identified by a UE transmit (Tx) scheme and a UE receive (Rx) scheme,
• wherein a configuration information including the first value and the second value is identified based on indication information included in a synchronization signal and physical broadcast channel (PBCH) block (SSB).

A method of a base station (BS), the method comprising:

• determining a configuration information of a user equipment (UE) based on indication information included in a synchronization signal and physical broadcast channel (PBCH) block (SSB), the configuration information corresponding to a first value or a second value;
• determining, based on the configuration information, an operation mode to identify a UE transmit (Tx) scheme and a UE receive (Rx) scheme, wherein the operation mode comprises a first operation mode corresponding to the first value or a second operation mode corresponding to the second value;
• and
• transmitting or receive signals based on the determined operation mode.
