Web4.1.7 Relation between bandwidth part and carrier aggregation. CA is a bandwidth-extension technology supported since the LTE-Advanced era, which can aggregate multiple component carriers (CC) for simultaneous reception or transmission. According to the range of aggregated carriers, CA can be divided into intraband CA and interband CA. WebLink adaptation is the means where network adapts the MCS transmitted (downlink), or instructs the device to adapt its MCSs (uplink). For EC-GSM-IoT link adaptation also involves the adaptation of the CC used. For the network to take a decision on the appropriate downlink MCS, the device is required to continuously measure (and …
