Abstract
The invention relates to a method for providing information from a machine device, in particular from a sensor device (S1), to a radio access network (RAN), comprising: transmitting, by the machine device (S1), a plurality of Random Access Channel preambles (P1 to P3) over a Random Access Channel, the information being encoded by transmitting the Random Access Channel preambles (P1 to P3) with frequency offsets (Δf) relative to each other. The invention also relates to a machine device, in particular to a sensor device (Sn), adapted to perform the encoding, and to a receiving device for decoding the encoded information.
Claims15
Method for providing information from a machine device, in particular from a sensor device, to a radio access network, comprising:
- transmitting, by the machine device, a plurality of Random Access Channel preambles over a Random Access Channel,
- wherein
- the information is encoded by transmitting the Random Access Channel preambles with pre-selected frequency offsets relative to each other.
Machine device, in particular sensor device, comprising:
- a transmission unit adapted for transmitting a plurality of Random Access Channel preambles over a Random Access Channel to a radio access network, and
- an encoding unit for encoding information to be provided to the radio access network over the Random Access Channel,
- wherein
- the encoding unit is adapted to encode the information by selecting frequency offsets between the Random Access Channel preambles to be transmitted by the transmission unit.
System for a radio access network comprising:
- a base station for communicating over a Random Access channel with at least one machine device wherein the base station is adapted to decode the information encoded in pre-selected frequency offsets between Random Access Channel preambles transmitted by the at least one machine device, and
- a plurality of machine devices, each comprising a transmission unit adapted for transmitting a plurality of Random Access Channel preambles over a Random Access Channel to a radio access network and an encoding unit for encoding information to be provided to the radio access network over the Random Access Channel, wherein the encoding unit is adapted to encode the information by selecting frequency offsets between the Random Access Channel preambles to be transmitted by the transmission unit.
