Abstract
The described technology is generally directed towards time division duplex (TDD) pattern configuration for cellular networks. Example methods can calculate TDD pattern configurations for use in 5G and subsequent generation networks. TDD pattern configurations can be calculated based on traffic demand, which can be estimated based on data channel demands, control channel requirements, user equipment (UE) capabilities, UE radio frequency (RF) conditions, and/or target quality of service (QoS) levels. Time offsets between downlink (DL) and uplink (UL) transmissions can be adjusted to meet service latency requirements and hardware limitations. Cells can opportunistically adopt different TDD patterns according to their individual traffic demands using semi-static and dynamic TDD pattern reconfiguration.
