Abstract

Embodiments of the present disclosure relate to dynamic partition resource allocation in 5G networks. Disclosed herein are apparatuses, systems, and methods for Dynamic Resource Allocation (DRA) of resources for Machine Type Communications (MTC) using or implementing as secondary partitions within a system bandwidth. The allocation other than the secondary partition is configured as a primary partition for communications other than MTC. When the DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC, the apparatus may perform MTC communication in the secondary partition. In addition, if the device is a device other than MTC, the device may avoid performing communication in the secondary partition. Other embodiments are also described.
