1. A method for operating a device in both a first network and a second network, the method comprising:
- monitoring transmission of synchronous connection oriented slots over the second network;
informing an access point (AP) in the first network not to transmit to the device before the end of a synchronous connection oriented slot by setting a network allocation control at the AP, wherein the network allocation control expires at the end of the synchronous connection oriented slot;
transmitting a power save trigger to the AP to retrieve buffered data from the AP, wherein the power save trigger is a power save poll, a data frame with a power management control, or an unscheduled asynchronous power save trigger, wherein the data frame with the power management control is transmitted in a next-inter synchronous connection oriented gap after sending clear to send data; and
transmitting data to the AP.

Abstract
Systems and methods for coexistence of WLAN and Bluetooth networks are described. At least one embodiment includes a method for operating a wireless device in both a 802.11 network and a Bluetooth network. In accordance with some embodiments, the method comprises monitoring transmission of Synchronous Connection Oriented (SCO) slots over the Bluetooth network, informing an access point (AP) in the 802.11 network not to transmit to the device before the end of an SCO slot, transmitting a power save trigger to the AP to retrieve buffered data from the AP, and transmitting data to the AP.

11. A wireless communication device capable of operating in both a first network and a second network, the device comprising
a timer module configured to monitor and determine a timing of synchronous connection slots; - and
a communications module configured to; notify an access point not to transmit data based on the timing of the synchronous connection slots; and transmit a power save control to retrieve the data from the access point, wherein the communications module notifies the access point not to transmit the data by setting a network allocation control such that the network allocation control expires at the end of a synchronous connection slot, wherein the power save control is a power save poll frame, a data frame with power management data, or an unscheduled asynchronous power save trigger frame, wherein the data frame with the power management data is transmitted in a next-inter synchronous connection slot gap after sending a clear to send frame. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for operating a wireless device in both a first network and a second network, the method comprising:
-
determining an end of a first synchronous slot; setting a network allocation control that ends at the same time as the end of the first synchronous slot at an access point (AP) in the first network so that the AP stops transmitting data to the device; transmitting a power save control to the AP to retrieve buffered data from the AP, wherein the power save control is one of a power save poll, a data frame with a power management control not set, and an unscheduled asynchronous power control, wherein the data frame with the power management control not set is transmitted in synchronous slot gap after sending a clear to send control; transmitting data to the AP during a period set by the network allocation control and prior to a beginning of the first synchronous slot; and receiving other data from the AP after the end of the first synchronous slot. - View Dependent Claims (18, 19, 20)
