Abstract

With the development of the 5G vertical industry, significantly improving uplink experience and shortening latency without changing downlink experience is a new requirement and challenge for networks. The uplink coverage of the 5G network is different from that of the downlink coverage due to different antenna quantity settings, meanwhile, the 5G network can better compensate for the problem of large loss caused by high frequency bands on the base station side. As a result, the downlink coverage performance is far greater than the uplink coverage in 5G network. This paper proposes an uplink and downlink decoupling SUL technology for enhancing uplink coverage performance of 5G network and an uplink enhancement technology for coordinating NR TDD and NR FDD so as to uplink data is transmitted on the SUL spectrum or the NR FDD spectrum by time-sharing of the uplink data. This greatly increases the available uplink time-frequency resources for 5G UEs.
