Abstract:
1. A system for use in a wireless device, the system comprising: first wireless protocol circuitry, wherein the first wireless protocol circuitry is configured to receive, transmit, and process first signals according to a first wireless protocol, wherein the first wireless protocol circuitry is configured to generate a request to perform a transmission or reception; second wireless protocol circuitry, wherein the second wireless protocol circuitry is configured to receive, transmit, and process second signals according to a second wireless protocol, wherein the second wireless protocol circuitry is configured to generate a request to perform a transmission or reception; a switch coupled to an antenna, wherein the antenna is used to perform wireless reception and transmission of the first signals and wireless reception and transmission of the second signals; and coexistence circuitry coupled to the first wireless protocol circuitry and the second wireless protocol circuitry; wherein the coexistence circuitry is configured to: receive a request from the first wireless protocol circuitry to perform transmission or reception; determine priority information for the first wireless protocol circuitry and the second wireless protocol circuitry in response to the request; determine a state of the second wireless protocol circuitry; determine a position of the switch based on the priority information for the first wireless protocol circuitry, the priority information of the second wireless protocol circuitry, and the state of the second wireless protocol circuitry; and wherein the coexistence circuitry uses a table to determine a desired switch position of the switch for performing the transmission or reception by the first wireless protocol circuitry, wherein the desired switch position is used as the position of the switch depending on the priority information for the first wireless protocol circuitry, the priority information of the second wireless protocol, and the state of the second wireless protocol circuitry.
