Title: Enabling URLLC in Uplink: Technical Realization, Challenges and Approaches
Speaker: Aleksei Shashin, IITP RAS, MIPT.
Abstract: Ultra-reliable low-latency communications (URLLC) is the key feature of fifth-generation cellular networks (5G). This service allows data transmission with about 1 ms latency and 99.999% reliability. In uplink, users suffer from additional delay caused by transmission of channel resource requests, which makes harder to provide low latency. To satisfy strict quality of service requirements, 3GPP significantly modified the specifications. In particular, a novel uplink channel access method was introduced called grant-free. With this method, the base station selects the user’s transmission parameters in advance to meet strict URLLC requirements even in case of channel degradation. The seminar will be devoted to discussing the technological aspects of enabling URLLC in the uplink. Special attention will be paid to the transmission parameters selection problem and approaches of its solution.
