LTE-Advanced represents the next generation of mobile broadband. ARM and CEVA look at the design considerations that are required to realize LTE-A devices. This paper presents an overview of the challenges in managing the constraints of throughput, low latency, and low power consumption. It then proposes a solution combining the technologies delivered by ARM and CEVA, using their CPU and DSP technologies. It also looks at wider system level design such as power saving modes, debug and trace along with the support of multi-mode operation, addressing not only LTE-A and LTE but also HSPA+, TD-SCDMA and other wireless technologies.
