RELAY SCHEME BETWEEN NARROW FREQUENCY BAND AND BROAD FREQUENCY BAND DEVICES

摘要

Methods, systems, and devices are described for improving uplink communications of machine type communication (MTC) devices. In some embodiments, an MTC device may perform a discovery operation on a first narrow frequency band, establish a first communication link with a discovered relay device on a second narrow frequency band, and transmit MTC data on the second narrow frequency band to the discovered relay device to be relayed to a third device on a second communication link on a broad frequency band. In another embodiment, a first device may participate in a discovery operation with a second device. The first device may establish a communication link with the second device on a first narrow frequency band and receive data from the second device on a second narrow frequency band. The first device may relay the data to a third device over a second communication link on a broad frequency band.
