Abstract:
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, and wherein the third and the fourth data frames are sleep frames.
