Abstract
A user equipment device (UE) may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and additional optimization requirements. The UE may use physical channels and procedures (e.g. it may receive and decode control channels) in a manner compatible with and not infringing on the operation of other UEs operating in the same network, while allowing the network more flexibility to assign resources. Specifically, resources for EPDCCH on UE-specific SS and EPDCCH on common SS may be shared. That is, the resources for two search spaces may be overlaid partially or in full, giving the network more flexibility in allocating resources. Furthermore the DCI formats for MPDCCH may be extended to devices operating according to the new device category, which enables the coverage enhancement of MTC for these devices.
