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; wherein the first wireless protocol circuitry and the second wireless protocol circuitry are configured to share at least one first antenna, wherein the first wireless protocol circuitry is configured to use at least one second antenna that is not shared with the second wireless protocol circuitry; coexistence circuitry configured to: receive a request from the first wireless protocol circuitry to perform transmission or reception; determine if the second wireless protocol circuitry is performing a transmission or reception; determine if the first wireless protocol circuitry is able to perform the transmission or reception using the at least one second antenna without using the at least one first antenna; determine whether to allow the first wireless protocol circuitry to perform transmission or reception based on the determination of whether if the first wireless protocol circuitry is able to perform transmission or reception using the at least one second antenna without using the at least one first antenna; and determine whether the requested transmission or reception from the first wireless protocol circuitry will conflict with a future transmission or reception of the second wireless protocol circuitry; wherein said determining if the first wireless protocol circuitry is able to perform the transmission or reception using the at least one second antenna without using the at least one first antenna is performed if either the second wireless protocol circuitry is performing a transmission or reception or if the requested transmission or reception will conflict with the future transmission or reception of the second wireless protocol circuitry.
