System and method for avoiding interference in a dual-signal device
First Claim
1. A method of operating a dual-signal wireless transceiver, comprising:
- transmitting and receiving first wireless signals via a first local transceiver using a first mode of a first protocol;
receiving a first request from a remote transceiver to transmit and receive second wireless signals via a second local transceiver using a first mode of a second protocol, after transmitting and receiving the first wireless signals;
transmitting and receiving third wireless signals via the first local transceiver using a second mode of the first protocol after receiving the first request;
disabling the second local transceiver from transmitting the second wireless signals while the receiving of the third wireless signals is being performed; and
transmitting and receiving the second wireless signals using a second mode of the second protocol, after the transmitting and receiving of the third wireless signals;
wherein the first protocol is a Worldwide Interoperability for Microwave Access (WiMAX) protocol;
wherein the first mode of the first protocol is a normal mode of operation of the WiMAX protocol;
wherein the second mode of the first protocol is a power save mode of operation of the WiMAX protocol;
wherein the power save mode of operation of the WiMAX protocol further involves allocating first, second, third, and fourth contiguous data frames,wherein the first data frame includes a first downlink portion and an unused portion,wherein the second data frame includes an uplink portion and a second downlink portion, andwherein the third and the fourth data frames are sleep frames.

Abstract
A dual-signal wireless transceiver is provided, comprising: a first wireless transceiver circuit configured to transmit and receive first signals using a first protocol; a second wireless transceiver circuit configured to transmit and receive second signals using a second protocol; and a control circuit configured to generate control signals to control operation of the first and second wireless transceiver circuits, wherein the first wireless transceiver circuit is configured to disable second transmission operations by the second wireless transceiver during first transmission operations by the first wireless transceiver circuit through the use of a shutdown signal. In this method, the second protocol allows the second wireless transceiver to retransmit first signals whose transmission was disabled by the shutdown signal. Furthermore, the second protocol is a Bluetooth protocol, and the first protocol is a wireless protocol other than the Bluetooth protocol.
