Scheduling of data transmission from internet of things user equipment to a base station of a cellular network

摘要

Data transmissions are scheduled from internet of things (IoT) user equipment (UEs) to a base station (BS) that serves those IoT UEs in a cellular network. A BS may broadcast synchronization information to the IoT UEs that allows the BS to calculate and use a schedule for receiving data transmissions from the UEs. This information can include a total number of the IoT UEs being serviced, a length of a spreading code to use in the schedule, a time domain periodicity of available resources, and a maximum number of the IoT UEs that can send data to the BS at one time. Each IoT UE can independently apply a mathematical operation to the broadcast information it receives to calculate and use the schedule. The BS can receive the data transmissions from each of the IoT UEs according to that schedule.
