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.
Claims25
A user equipment (UE) comprising:
- one or more wireless transceivers configured to communicate using a first radio access technology (RAT) and a second RAT, wherein the first RAT and second RAT are serviced by one or more enhanced node Bs (eNBs);
- circuitry configured to:
- receive from one of the one or more eNBs scheduling information for the second RAT using the first RAT;
- and
- receive or transmit a message according to the scheduling information using the second RAT.
A computer program product comprising a computer-readable storage medium storing program code for causing one or more processors to perform a method, the method comprising:
- transmitting scheduling information using a first radio access technology (RAT) partition for a second RAT partition;
- and
- receiving from a user equipment (UE) or transmitting to a UE a message according to the scheduling information using the second RAT partition.
A wireless device configured to:
- determine downlink time and frequency synchronization information for a primary radio access technology (P-RAT) provided by one or more base stations;
- decode access information data provided by the one or more base stations using the P-RAT for a secondary radio access technology (S-RAT);
- detect downlink synchronization signal using the S-RAT within a search window provided by the one or more base stations;
- and
- transmit or receive data using the S-RAT to the one or more base stations based at least in part on the access information from the P-RAT.
