Method and apparatus for improving coexistence performance by measurements in wireless communication systems

A network entity for a coexistence operation in a wireless communication system, the network entity comprising:

• a transceiver configured to receive, from a base station (BS), a registration request comprising a first measurement report based on a first measurement of first signals, wherein the first measurement is based on the first signals transmitted from neighbor BSs over channels the BS shares with the neighbor BSs before transmission of a spectrum access grant to the BS;
• and
• at least one processor operably connected to the transceiver, the at least one processor configured to generate the spectrum access grant based on the registration request comprising the first measurement report,
• wherein the transceiver is further configured to transmit, to the BS, the spectrum access grant for a second measurement of second signals transmitted from the neighbor BSs over the channels the BS shares with the neighbor BSs performed after transmitting the spectrum access grant to the BS.

A method of operating a base station (BS) for a coexistence operation in a wireless communication system, the method comprising:

• performing a first measurement of first signals received from neighbor BSs over channels that are shared with the neighbor BSs before receipt of a spectrum access grant from a network entity;
• generating a registration request comprising a first measurement report based on the first measurement of the first signals;
• transmitting, to the network entity, the registration request comprising the first measurement report of the first signals;
• receiving the spectrum access grant from the network entity;
• and
• performing a second measurement of second signals received from the neighbor BSs over the channels that are shared with the neighbor BSs after receiving the spectrum access grant from the network entity.
