In this paper, we focus on intra-band CA with contiguous CCs and inter-band CA with non-contiguous CCs.
Three types of CA have been defined by 3GPP [2]: 1) intra-band CA with contiguous CCs, 2) intra-band CA with non-contiguous CCs, and 3) inter-band CA with non-contiguous CCs.
Option a) is only applicable for intra-band CA with contiguous CCs, because it cannot filter undesired frequency bands between the non-contiguous CCs.
Two contiguous CCs each with 20 MHz bandwidth are configured for intra-band CA in this scenario.

This algorithm targeted the CA of inter-band non-contiguous CCs.
● A concept of CA is utilized here which corresponds to the aggregation of contiguous and non-contiguous CCs.
Note that, unlike MSSLM and PSLM, in SSLM, the complexity increases only linearly with a larger P. To evaluate MIMO CA systems without complexity burden, we use two non-contiguous CCs (300 MHz apart) and Nt = 2 antennas for both UL and DL system.
LTE handsets can carry out this operation when all the CCs are contiguous, including the licensed LTE band [2].
