Dual band wireless local area network (WLAN) transceiver

摘要

Dual band wireless local area network (WLAN) transceiver. A wireless communication device includes at least two different transceivers (or radios) therein to effectuate communications with other wireless communication devices using at least two respective frequency bands. Each of these two transceivers may have different respective circuitry (e.g., each may have a different respective power amplifier (PA) and/or other circuitry components). Coordination is made regarding when certain components of one transceiver turn on and operate when another transceiver may be transmitting or receiving communications. For example, the turn on of a PA and/or other circuitry components (e.g., such as components using or requiring high current) within one transceiver can be coordinated as to minimize deleterious effects regarding the operation of another transceiver. Moreover, latency existent within each of the respective transceiver chains within the wireless communication device (e.g., including baseband and radio portions) is accounted for regarding their respective concurrent operation.

1. A method for execution by a wireless communication device, the method comprising:
operating a first radio to support communications via a first band; operating a second radio to support communications via a second band; when the first radio receives a first communication, estimating location of a first guard interval within the first communication and turning on at least one analog component within the second radio at a beginning of the first guard interval based on the second radio subsequently transmitting a second communication; and when the first radio transmits a third communication, turning on the at least one analog component within the second radio at a beginning of a second guard interval within the third communication based on the second radio subsequently transmitting a fourth communication.
