Method for supporting beam correspondence and apparatus thereof

A method for supporting beam correspondence, the method performed by a user equipment (UE) and comprising:

• determining beam correspondence based on at least a beam correspondence tolerance requirement,
• wherein the beam correspondence tolerance requirement includes a delta effective isotropic radiated power (EIRP) of 3 dB,
• wherein the delta EIRP of 3 dB is determined based on a first EIRP and a second EIRP,
• wherein the first EIRP is based on a beam the UE chooses, and
• wherein the second EIRP is the highest EIRP based on an uplink beam sweeping;
• transmitting UE capability information to the base station,
• wherein the UE capability information includes first information related a capability of supporting beam correspondence, based on the determined the beam correspondence.

An apparatus operable for a user equipment (UE) to support beam correspondence, the apparatus comprising:

• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• determining beam correspondence based on at least a beam correspondence tolerance requirement,
• wherein the beam correspondence tolerance requirement includes a delta effective isotropic radiated power (EIRP) of 3 dB,
• wherein the delta EIRP of 3 dB is determined based on a first EIRP and a second EIRP,
• wherein the first EIRP is based on a beam the UE chooses, and
• wherein the second EIRP is the highest EIRP based on an uplink beam sweeping;
• transmitting UE capability information to the base station,
• wherein the UE capability information includes first information related a capability of supporting beam correspondence, based on the determined the beam correspondence.

A user equipment (UE) to support beam correspondence, the apparatus comprising:

• a transceiver;
• at least one processor operably connectable to the transceiver;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• determining beam correspondence based on at least a beam correspondence tolerance requirement,
• wherein the beam correspondence tolerance requirement includes a delta effective isotropic radiated power (EIRP) of 3 dB,
• wherein the delta EIRP of 3 dB is determined based on a first EIRP and a second EIRP,
