1. A communications method, for an apparatus capable of Carrier Aggregation (CA), wherein the apparatus comprises a plurality of processing engines and antennas, comprising:
determining whether the apparatus is configured in a single component carrier for a first group of the antennas; activating a second group of the antennas when the apparatus is configured in the single component carrier, wherein the first group of antennas are configured for a first part of the processing engines and the second group of antennas are configured for a second part of the processing engines when the apparatus is configured in the single component carrier, wherein the first part of the processing engines and the second part of the processing engines share a MIMO pre-processor; performing a symbol combining processing, wherein the first part of the processing engines and the second part of the processing engines share a MIMO pre-processor, wherein the first part of the processing engines and the second part of the processing engines share a MIMO pre-processor and a MIMO detector, and using an antenna selector, connected with the MIMO detector, to select the antennas to activate according to indicators from the MIMO detector.
