  • Patent number: 10764907
    Abstract: 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.

The usage data is analyzed for an average group usage of each category across the sessions and a variation of the average group usage of each category across the sessions. Individual usage data is also collected for usage activities of at least one user on the categories of content. The individual usage data reflects an aggregated usage of each category for the at least one user. Category usage is estimated on each category for the at least one user based on a weighted combination of the aggregated usage and the average group usage according to the variation.
