Carrier Aggregation (CA) allows the network and User Equipment (UE) to aggregate carrier frequencies in licensed, unlicensed, or Shared Access (SA) bands of the same or different spectrum bands to boost the achieved data rates. This work aims to provide a detailed study on CA techniques for 5G New Radio (5G NR) networks while elaborating on CA deployment scenarios, CA-enabled 5G networks, and radio resource management and scheduling techniques. We analyze cross-carrier scheduling schemes in CA-enabled 5G networks for Downlink (DL) resource allocation. The requirements, challenges, and opportunities in allocating Resource Blocks (RBs) and Component Carriers (CCs) are addressed. The study and analysis of various multiband scheduling techniques are made while maintaining that high throughput and reduced power usage must be achieved at the UE. Finally, we present CA as the critical enabler to advanced systems while discussing how it meets the demands and holds the potential to support beyond 5G networks, followed by discussing open issues in resource allocation and scheduling techniques.

“…The fifth‐generation (5G) of mobile communications drives network services across different sectors, including finance, transport, education, health, and so on 1 . Emerging spectrum resources and the application of carrier aggregation 2 allow more channel capacity and a faster communication rate. However, they also bring more sophisticated spectrum scheduling and great challenges to the compatibility of broadband transmitters because the carrier aggregation can be noncontinuous and continuous.…”

This paper proposes a single and dual-band compatible digital predistortion (SDBC-DPD) for broadband transmitters with carrier aggregation. Since complicated spectrum scheduling, the stimuli of the power amplifiers (PAs) can be single-band and dual-band. The proposed SDBC-DPD scheme can well linearize a dual-band signal in a conventional 1-D-DPD way utilizing a spectrum splicing and segmentation method. A series of experiments were carried out on a dual-band test bench based on a 3.0-4.0 GHz PA. The stimuli with different bandwidths and sampling rates were used in the experiments. Measurement results show that the SDBC-DPD can well mitigate the nonlinearity in the dual-band signals and needs a much lower sampling rate for model identification.
