Abstract

In a particular aspect, a method includes performing a first communication operation associated with a first frequency band using an antenna of a wireless device. The first communication operation is initiated by first communication circuitry of the wireless device. The first communication circuitry is associated with a first communication protocol. The method further includes, based on a duration of a second communication operation, performing the second communication operation associated with a second frequency band using the antenna of the wireless device. The second communication operation is initiated by second communication circuitry of the wireless device. The second communication circuitry is associated with a second communication protocol that is different than the first communication protocol. The first frequency band at least partially overlaps the second frequency band.

based on a duration of a second communication operation, performing the second communication operation associated with a second frequency band using the antenna of the wireless device, wherein the second communication operation is initiated by second communication circuitry of the wireless device, wherein the second communication circuitry is associated with a second communication protocol that is different than the first communication protocol, and wherein the first frequency band at least partially overlaps the second frequency band; and
performing periodic communication operations associated with the second frequency band using the antenna, wherein the periodic communication operations are performed multiple times, and wherein the periodic communication operations include the second communication operation.

2. The method of claim 1 , further comprising causing a switch to couple the second communication circuitry to the antenna prior to performing the second communication operation.

3. The method of claim 1 , further comprising disabling data transmission from the first communication circuitry to the antenna during performance of the second communication operation.

4. The method of claim 1 , further comprising performing a third communication operation associated with the first frequency band using the antenna after completion of the second communication operation.

5. The method of claim 1 , wherein the second frequency band comprises a 5 gigahertz (GHz) channel.

6. The method of claim 1 , wherein a criticality bit associated with the periodic communication operation indicates whether the periodic communication operation is critical.

7. The method of claim 1 , further comprising performing a third communication operation associated with the first frequency band using the antenna after performance of the second communication operation and prior to performance of another of the periodic communication operations.
