User device, wireless communication method implemented by user device

Abstract

The invention relates to a wireless communication technique for antenna circuit diversity and simultaneous multi-SIM operation management. Specifically, the invention relates to a user device, a wireless communication method performed by the user device (UE) capable of communicating via a link with the first subscriber identification module (SIM). The transmission path can be mapped to one or more primary antennas suitable for determining whether the UE supports at least one of frequency-division duplex (FDD) or time-division duplex (TDD) antenna switching diversity when simultaneously performing wireless communication associated with the first SIM and wireless communication associated with the second SIM. The UE can also communicate via at least one receive link associated with a second SIM. At least one receive link can be mapped to one or more secondary antennas, depending on whether the UE supports at least one of the antenna switching diversity (FDD) or antenna switching diversity (TDD) types.
