摘要/Abstract

摘要： 视频服务需求的快速增长对于视频流畅播放提出了巨大挑战,从用户体验角度分析,视频播放中的卡顿时间可能是最重要指标之一。随着5G网络技术的发展,非正交多址接入(NOMA)技术被重点关注,NOMA技术具有叠加编码和连续干扰消除2个特点,根据这2个特点实现数据的并行传输。利用NOMA技术的并行传输能力来提高基站为用户提供视频的实时性。在用户需求视频名称和视频分辨率给定的情况下,通过联合基站-用户配对方式和基站功率分配来降低视频播放时的卡顿时间。通过对问题进行建模,并提出1个两步启发式算法对问题进行求解,第1步为确定基站与用户的配对方式,第2步为分配基站的发射功率。实验结果表明,基于NOMA的传输调度方案与传统的传输调度方案相比,用户需求的平均卡顿时间有明显的下降,相对于在不采用NOMA机制时,在2-SIC接收机情况下,用户平均卡顿时间减少了55.56%。

Abstract: The rapid growth in demand for video services poses a significant challenge for smooth video playback. From a user-experience perspective, the jamming time during video playback may be one of the most critical indicators. With the development of 5G network technology, Non-Orthogonal Multiple Access (NOMA) technology has received special attention. The NOMA technology has two characteristics: Superimposed Coding(SC)and Continuous Interference Cancellation(SIC). Parallel data transmission can be achieved based on these characteristics. The parallel transmission capability of NOMA technology is used to improve the real-time performance of Base Stations(BS) that provide videos to users. By combining BS user pairing and BS power allocation, the jamming time during video playback can be shortened, given the video name and resolution required by the user. By modeling the problem and proposing a two-step heuristic algorithm to solve it, the first step is to determine the pairing method between the BS and user, and the second step is to allocate the transmission power of the BS. The experimental results show that, compared with traditional transmission scheduling schemes, the NOMA-based transmission scheduling scheme exhibits a significant decrease in the average jamming time required by users. Compared with the case of 2-SIC receivers without the NOMA mechanism, the average jamming time of users decreases by 55.56%.

Key words: jamming time, Non-Orthogonal Multiple Access(NOMA), video transmissions, Superimposed Coding(SC), power allocation
