Transceiver arrangement

1. An arrangement for a receiver which is adapted to allow carrier aggregation in a wireless communication system, comprising a plurality of radio frequency (RF) blocks, each of which is inherently adapted to operate substantially across one of the following particular groups of frequency ranges, in MHz, of:

A) 698-960;

B) 1428-1660;

C) 1710-2200;

D) 2300-2690;

E) 3400-3800;

the arrangement being adapted to operate in a multiple antennas and/or a multiple input/multiple output (MIMO) system, wherein, for each channel/antenna, there are provided two RF amplifiers adapted for group A, one RF amplifier adapted for group C and one RF amplifier adapted for group D, the arrangement further adapted to operate over two channels of a MIMO system, and having an input and/or output to the respective antenna of each channel; wherein for each channel there is a first multiplexer to multiplex the output from one of the RF amplifiers adapted for group A, with the output from the RF amplifier adapted for group C, and a second multiplexer to multiplex the output from the other group A adapted amplifier with the output from the group C adapted amplifier and the output from the group D adapted amplifier.

2. The arrangement of claim 1 further adapted for downlink, and wherein the frequency ranges for groups A, B and C are in the region, in MHz, of:

A) 728-960;

B) 1476-1559;

C) 1805-2200.

3. The arrangement of claim 1 further adapted for uplink, and wherein the frequency ranges for groups A, B and C are in the region, in MHz, of:

A) 698-915;

B) 1428-1660

C) 1710-2020.

4. The arrangement of claim 1 , wherein said frequency ranges are such so as to at least span the following E-UTRA frequency bands, for each corresponding group:

A) 5, 6, 8, 12-14, 17-20;

B) 11, 21, 24;

C) 1-4, 9, 10, 23, 25, 33-37, 39;

D) 7, 38, 40, 41;

E) 42, 43.

5. The arrangement of claim 1 wherein said radio frequency blocks comprise RF amplifiers.

6. The arrangement of claim 5 wherein said RF amplifiers are tunable across the range of the group.

7. The arrangement of claim 1 , wherein the RF blocks are adapted for three groups.

8. The arrangement of claim 7 , wherein the RF blocks are adapted for groups A, C and D.

9. The arrangement of claim 8 which is adapted to provide inter-band carrier aggregation for any of the following carrier aggregation schemes, wherein the following letters represent said groups into which the aggregated bands fall: A-A, A-C, A-D and C-D.

10. The arrangement of claim 1 further arranged such that the multiplexing is performed after down-conversion of the outputs from the RF amplifiers.

11. The arrangement of claim 1 , further including, for each channel, one RF amplifier adapted for group E and/or one RF amplifier adapted for group B.

12. The arrangement of claim 11 wherein the outputs from the amplifier(s) adapted for groups E and/or B have inputs to a multiplexer.

13. The arrangement of claim 1 , which provides intra-band carrier aggregation with respect to any band provided by the RF amplifiers.

14. The arrangement of claim 1 , having means for feeding the output of the band C RF amplifier to both multiplexers simultaneously so as to support intra-band carrier aggregation for bands in frequency group C.

15. The arrangement of claim 1 , having outputs of said multiplexers fed into IF support chains able to support IF paths of up to 100 MHz.

16. A user equipment or base station including an arrangement as claimed claim 1 .
