Description

Telecommunication system Introduction to the invention The present disclosure is in the field of telecommunications systems. In fifth generation ("5G") cellular telecommunication systems, communication of user data may be accomplished primarily through 5G communication. In addition to being connected via 5G, user equipment ("UE") may also be connected via fourth generation long term evolution ("LTE") simultaneously to enhance overall system capacity and reliability. The dominant mode of 5G communication may be below 6 gigahertz ("sub-6") in some cases. However, in some cases, a cell group operating in millimeter wave mode ("mmWave") (5G mode, which may provide a higher average downlink speed) may be added. However, the inventors have noted that when mmWave secondary cell groups are added, communication quality may decrease until connection with the mmWave secondary cell groups is completed and communication is established and stabilized. Such degradation in quality may be due to scheduling and resource allocation, not due to changing channel conditions or environmental factors, and may occur even when the user equipment is stationary at a fixed location. In systems where timely and reliable communication is important, degradation in quality may be a disadvantage. Furthermore, as long as the signal conditions of the mmWave communication are sufficient, the connection of the mmWave communication in the current system may occur even if the user equipment does not need it, it is possible that, at least for a period of time, an interruption associated with establishing the mmWave communication will actually result in a reduced communication quality. Furthermore, the operation of the cellular telecommunication system may be enhanced by valuable operation information that the user equipment may provide. Disclosure of Invention A method for operating a cellular telecommunications system for communicating with user equipment includes operating in a first mode and a second mode, the second mode being a backup or complement of communications in the first mode. The method also includes adding one or more secondary cell groups operating in a third mode, and after adding the one or more secondary cell groups, communicating in the first mode, the second mode, and the third mode. The first mode may have a higher average downlink throughput than the second mode. Further, the secondary cell group may operate at a higher average downlink throughput than the first mode and the second mode. The first mode may be a fifth generation ("5G") sub-6 gigahertz ("sub-6") communication mode, the second mode may be a long term evolution ("LTE") communication mode, and the secondary cell group may operate in a millimeter wave ("mmWave") communication mode. In a method for operating a cellular telecommunication system, the estimated time of connection may be a function of Ps, pe and v, where Ps is the location where the user equipment provides measurement reports to the telecommunication system, pe is the location where the user equipment releases at least one mmWave cell, and v is the average speed of the user equipment. Alternatively, the estimated time of connection may be a function of Pc, pe, pi and v, where Pc is the position at which the user equipment receives the millimeter wave measurement configuration, pe is the position at which the user equipment releases the at least one mmWave cell, pi is the position at which the user equipment enters the mmWave coverage, and v is the average speed of the user equipment. In a method for operating a cellular telecommunication system, a first mode may carry control plane data for controlling the telecommunication system and first user plane data of a user equipment. The second mode may carry second user plane data of the user equipment. The third mode may carry third user plane data of the user equipment.
