45、mponents. 5 Support of wider bandwidth 5.1 General LTE-Advanced extends LTE Rel.-8 with support for Carrier Aggregation, where two or more component carriers (CCs) are aggregated in order to support wider transmission bandwidths up to 100MHz and for spectrum aggregation. It shall be possible to conf
46、igure all component carriers which are LTE Rel-8 compatible, at least when the aggregated numbers of component carriers in the UL and the DL are the same. Not all component carriers may necessarily be LTE Rel-8 compatible. A terminal may simultaneously receive or transmit one or multiple component c
47、arriers depending on its capabilities: ETSI ETSI TR 136 912 V14.0.0 (2017-04)93GPP TR 36.912 version 14.0.0 Release 14- An LTE-Advanced terminal with reception and/or transmission capabilities for carrier aggregation can simultaneously receive and/or transmit on multiple component carriers. - An LTE
48、 Rel-8 terminal can receive and transmit on a single component carrier only, provided that the structure of the component carrier follows the Rel-8 specifications. Carrier aggregation is supported for both contiguous and non-contiguous component carriers with each component carrier limited to a maxi
49、mum of 110 Resource Blocks in the frequency domain using the LTE Rel-8 numerology It is possible to configure a UE to aggregate a different number of component carriers originating from the same eNB and of possibly different bandwidths in the UL and the DL. In typical TDD deployments, the number of component carriers and the bandwidth of each component carrier in UL and DL will be the same. Component carriers originating from the same eNB need not to provide the same coverage. The spacing between centre frequencies of contiguously aggregated componen
