First Claim
1. A method for communication, comprising:
- in a wireless device, establishing a first connection with a base station (BS) of a long-range wireless data network, and a second connection on a Wireless Local Area Network (WLAN);
selecting in the wireless device a time interval for communicating over the second connection;
in preparation for the selected time interval, causing the BS to refrain from scheduling data transmission from the wireless device to the BS over the first connection during the time interval, by reporting to the BS prior to the time interval that no data is pending for transmission from the wireless device, even when some data is actually pending for transmission to the BS; and
communicating using the wireless device over the second connection on the WLAN during the time interval;
wherein reporting that no data is pending is performed even when some data is pending for transmission to the BS, so as to cause the BS to schedule transmission of the pending data outside the time interval.

Abstract
A method for communication in a wireless device (24) includes establishing a first connection with a base station (BS-28) of a long-range wireless data network, and a second connection on a Wireless Local Area Network (WLAN). A time interval (96) is selected in the wireless device for communicating over the second connection. In preparation for the selected time interval, the BS is caused to refrain from scheduling data transmission from the wireless device to the BS over the first connection during the time interval, by reporting to the BS prior to the time interval that no data is pending for transmission from the wireless device. The wireless device communicates over the second connection on the WLAN during the time interval.

7. A wireless device, comprising:
-
a Radio Frequency (RF) front end, which is configured to exchange RF signals so as to communicate on a long-range wireless data network and on a Wireless Local Area Network (WLAN); and baseband circuitry, which is configured to establish, via the RF front end, a first connection with the BS of the long-range wireless data network and a second connection on the WLAN, to select a time interval for communicating over the second connection, to cause the BS, in preparation for the selected time interval, to refrain from scheduling data transmission from the wireless device to the BS over the first connection during the time interval by reporting to the BS prior to the time interval that no data is pending for transmission from the wireless device, even when some data is actually pending for transmission to the BS, and to communicate using the wireless device over the second connection on the WLAN during the time interval; wherein reporting that no data is pending is performed even when some data is pending for transmission to the BS, so as to cause the BS to schedule transmission of the pending data outside the time interval.

8. A method for communication, comprising:
-
in a wireless device, establishing a first connection with a base station (BS) of a long-range wireless data network in an interleaved sequence of uplink intervals, for transmitting to the BS, and downlink intervals, for receiving from the BS; establishing in the wireless device, concurrently with the first connection, a second connection with a station of a Wireless Local Area Network (WLAN) that is located in close proximity to the wireless device; and preventing interference from out-of-band transmission of the station on the second connection to reception of the BS on the first connection, by transmitting signals from the wireless device to the station so as to block the station from transmitting during the downlink time intervals; wherein preventing the interference comprises scheduling transmissions from the wireless device to the station such that respective acknowledgements from the station occur during the uplink intervals of the first connection. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
