A Novel Uplink Coverage and Capacity Enhancement Scheme in NR TDD Network

The NR TDD network adopts large bandwidth and high frequency band networking, and the characteristics of high frequency band will lead to large 5G wireless pathloss. On the uplink, the UE transmit power and the antenna port configuration of the terminal is less than those of the base station. In the process of services, users may encounter service difficulties due to the limited uplink coverage performance. This document describes a coverage and capacity enhancement solution. The coverage enhancement solution is based on MR and MDT data from the n28 band, which indicates the limitation scenarios of the n41 band. The MR and MDT sampling points have been collected in the maintenance platform as well as intra-system and different frequency points and RSRP of the 5G cell in the n28 band. The capacity enhancement solution is based on the overlay scenario of the NR TDD network with strong master control, the uplink time slot is added to the class A cell and the uplink capacity can be improved without interfering with class B cell.
