Abstract:
Embodiments of methods and systems according to the application can transmit voice data by using a wireless LAN and a Bluetooth. One system embodiment can include a headset, an AP, and a terminal device to communicate with the headset according to a first protocol (e.g., Bluetooth) to transmit downlink voice data to the headset and to receive uplink voice data from the headset and to communicate with the AP according to a second protocol (e.g., wireless LAN) to transmit the uplink voice data to the AP and to receive the downlink voice data from the AP. The terminal device can receive the downlink voice data from the AP after the terminal device sends a PS-Poll frame to the AP within a period during which a transmission/reception between the terminal device and the headset is not to be performed.
