Abstract:
In this paper, we focus on the resource scheduling of Long Term Evolution - Advanced (LTE-A) with Carrier Aggregation (CA). Application of CA meets the demand of bandwidth in LTE-A by aggregating several discrete carriers together. With different fading characters, the aggregated carriers have different coverage between each other. Considering the backward compatibility, there exist both LTE-A and LTE users. In order to improve the performance of LTE users and cell edge users, an improved proportional fair (PF) scheduling algorithm suitble to multi-carrier system is proposed. In this algorithm, a variable to limit the number of carriers each user can access is set, and a carrier weight factor which is composed of carrier coverage weight factor and user category weight factor is introduced. Simulation results show that the proposed algorithm can effectively improve the performance of cell edge users and LTE users.
