Abstract
User equipment and base stations can enable access to secondary radio access technology (S-RAT) a cross radio access technology (RAT) scheduling between a primary RAT (P-RAT) and a secondary RAT (S-RAT) and/or cross-scheduling in a same RAT with different optimizations and use/partition for different applications (e.g. a regular partition with a carrier resource (referred to as P-RAT) and an additional resource partition/region for device-to-device (D2D) or machine-type-communication (MTC) application (referred to as S-RAT)). Cross-RAT/partition-scheduling can include when S-RAT is scheduled by P-RAT or when P-RAT is scheduled by S-RAT.
