The study item covers technology components to be considered for the e
46、volution of E-UTRA, e.g. to fulfil the requirements on IMT-Advanced. This technical report covers all RAN aspects of these technology components. 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)
47、are aggregated in order to support wider transmission bandwidths up to 100MHz and for spectrum aggregation. It shall be possible to configure 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 c
48、omponent carriers may necessarily be LTE Rel-8 compatible. A terminal may simultaneously receive or transmit one or multiple component carriers depending on its capabilities: ETSI ETSI TR 136 912 V15.0.0 (2018-07)93GPP TR 36.912 version 15.0.0 Release 15- An LTE-Advanced terminal with reception and/
49、or transmission capabilities for carrier aggregation can simultaneously receive and/or transmit on multiple component carriers. - An LTE 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 maximum of 110 Resource Blocks in the frequency domain using the LTE Rel-8 numerology It is possible to configure a UE to ag
