After the UE 300 allocates the available transceiver resources 310 to the available CCs 220, FIG. 2A shows the UE 300 transmitting an allocation message 206 to the at least one eNB 102 of the carrier aggregation capable network 100. Here, the allocation message 206 indicates the allocation of the available transceiver resources 310 to the available CCs 220. The UE 300 may transmit the allocation message 206 over the first CC1 220a corresponding to the primary CC 220P. The at least one eNB 102 may use the allocation message 206 to identify the transceiver resources 310 allocated to each available CC 220 at the UE 300 and thereafter send instructions to the UE 300 to activate each of the CCs 220 for operation in the CA mode. FIG. 2B shows the UE 300 operating on each of the component carriers CC1-CCn component carriers (CCs) 220 are aggregated and jointly used for transmission of data 208 between the UE 300 and the eNB 102. FIG. 2B shows the UE 300 supporting a 4×4 MIMO configuration while operating on the first CC1 and supporting the 2×2 MIMO configuration while operating on the remaining CCn. The UE 300 is not configured to support MIMO configurations while operating on the second CC2.
