Publication number: 20230147527Abstract: Solutions pertaining to allocating antennas of a user equipment (UE) between connections using different RATs are proposed. A UE has a first connection to a first network and a second connection to a second network, each connection employing a respective radio access technology (RAT). During operation, the UE may identify a precondition of reconfiguring the connections. For example, the UE may intend to change a multi-input-multi-output (MIMO) setting of the first connection in order to release some antennas that can be allocated to the second connection to relieve a communication bottleneck thereof. Prior to reconfiguring the connections, the UE may communicate its intent to the first network. The UE may not reconfigure the connections until a confirmation is received from the first network.Type: ApplicationFiled: November 1, 2022Publication date: May 11, 2023Inventors: Chiao-Chih Chang, Che-Li Lin
