Abstract

As disclosed herein is a multiple-input multiple-output (MIMO) radio transceiver which may include a plurality of antennas operatively coupled to a first integrated circuit (IC). The first IC and the plurality of antennas may receive a first radio signal on a first radio frequency (RF) carrier and a second radio signal on a second RF carrier. The first RF carrier and the second RF carrier may be different carriers. The first radio signal and the second radio signal may have different bandwidths. The first IC may demodulate the first received radio signal to produce a first baseband signal and the second received radio signal to produce a second baseband signal. A second IC may be operatively coupled to the first IC and may recover data from at least the first baseband signal and the second baseband signal.

First claim

The invention claimed is:

1. A mobile apparatus comprising:
a plurality of antennas;
a first integrated circuit operatively coupled to the plurality of antennas, the first integrated circuit and the plurality of antennas configured to simultaneously receive a first radio data signal on a first radio frequency (RF) carrier allocated to a radio communications system and a second radio data signal on a second RF carrier allocated to the radio communications system; wherein the first RF carrier and the second RF carrier are different carriers, and wherein the first radio data signal and the second radio data signal have bandwidths different from each other;
the first integrated circuit further configured to demodulate the first received radio data signal to produce a first baseband signal and demodulate the second received radio data signal to produce a second baseband signal; and
a second integrated circuit, operatively coupled to the first integrated circuit, configured to recover data from at least the first baseband signal and the second baseband signal.

2. The apparatus of claim 1 , wherein the at least first baseband signal or the at least second baseband signal of the received signals is received using a multiple-input multiple-output (MIMO) scheme.

3. The apparatus of claim 1 , wherein the first integrated circuit is a single integrated circuit.

4. The apparatus of claim 1 , wherein the second integrated circuit is a baseband processor.

5. The apparatus of claim 1 , wherein a bandwidth for the first radio data signal is larger than a bandwidth for the second radio data signal.

6. The apparatus of claim 1 , wherein the bandwidths are frequency bandwidths.

7. The apparatus of claim 1 , wherein the first radio data signal and the second radio data signal are received at different data rates.

8. A method for use by a mobile apparatus comprising:
receiving, by a plurality of antennas and a first integrated circuit of the apparatus, simultaneously a first radio data signal on a first radio frequency (RF) carrier allocated to a radio communications system and a second radio data signal on a second RF carrier allocated to the radio communications system; wherein the first RF carrier and the second RF carrier are different carriers, and wherein the first radio data signal and the second radio data signal have bandwidths different from each other;
demodulating, by the first integrated circuit of the apparatus, the first received radio data signal to produce a first baseband signal and demodulating, by the first integrated circuit of the apparatus, the second received radio data signal to produce a second baseband signal; and
recovering, by a second integrated circuit of the apparatus, data from at least the first baseband signal and the second baseband signal.

9. The method of claim 8 , wherein the at least first baseband signal or the at least second baseband signal of the received signals is received using a multiple-input multiple-output (MIMO) scheme.

10. The method of claim 8 , wherein the first integrated circuit is a single integrated circuit.

11. The method of claim 8 , wherein the second integrated circuit is a baseband processor.

12. The method of claim 8 , wherein a bandwidth for the first radio data signal is larger than a bandwidth for the second radio data signal.

13. The method of claim 8 , wherein the bandwidths are frequency bandwidths.

14. The method of claim 8 , wherein the first radio data signal and the second radio data signal are received at different data rates.
