Measuring signal strength in a multiple-input multiple-output antenna environment

1. A method of operating a wireless communication device, comprising:

operating the wireless communication device in a M by N multiple-input multiple-output (MIMO) mode, wherein M is a number of antennas transmitting to the communication device from a first base station, and wherein N a number of receiving antennas and receivers, and wherein M is an integer greater than zero and N is an integer greater than one;

operating the wireless communication device in an M by N−1 MIMO mode while a first one of the N receiving antennas and a first one of the N receivers receives wireless communication from a second base station;

operating the wireless communication device in a MIMO mode wherein a data stream is split into multiple lower rate data streams and each data stream is transmitted from a different transmit antenna in the same frequency channel; and

operating the wireless communication device in a space-time coding MIMO mode while scanning for the second base station.

2. The method of claim 1 , wherein M=2 and N=2.

3. The method of claim 1 , further comprising:

receiving M streams of data on a single frequency channel; and,

receiving a single stream of data on the single frequency channel.

4. The method of claim 3 , further comprising:

receiving a control message from the first base station to switch the wireless communication device from spatial multiplexing MIMO mode to space-time coding MIMO mode.

5. The method of claim 3 , further comprising:

sending a request to the first base station to switch the wireless communication device from spatial multiplexing MIMO mode to space-time coding MIMO mode.

6. The method of claim 5 , wherein the wireless communication device begins scanning after the request to the first base station is granted.
