Abstract
Systems and methods described herein may introduce an intermediary device between radio access networks using a first spectrum and user equipment using a second spectrum. The intermediary device may process communication signals from either the first spectrum or the second spectrum into a format usable by the other of the first spectrum or the second spectrum. The intermediary device may be referred to as a multi-radio access technology (multi-RAT) translator.
Claims19
An electronic device comprising:
- a receiver;
- a transmitter;
- and
- processing circuitry coupled to the receiver and the transmitter, the processing circuitry configured to
- receive a signal from a base station having a first frequency in a first frequency spectrum at the receiver,
- convert the signal from the first frequency to a second frequency in a second frequency spectrum, and
- transmit the signal having the second frequency to user equipment using the transmitter based on a previously received scheduling data including a time shift from the user equipment, the scheduling data generated based on a Physical Downlink Control Channel (PDCCH) message directly received by the user equipment from the base station.
4 more elements
A method comprising:
- receiving, via a translator device configured to intercept communications between a base station and user equipment, an input signal from the base station via a first frequency spectrum;
- generating, via the translator device, an output signal communicable on a second frequency spectrum based on the input signal;
- receiving, via the translator device, scheduling data from the user equipment, the scheduling data including a time shift, the scheduling data generated based on a Physical Downlink Control Channel (PDCCH) message directly received by the user equipment from the base station;
- and
- transmitting, via the translator device, the output signal to the user equipment via the second frequency spectrum based on the scheduling data.
2 more elements
A system comprising:
- a first device configured to use a first frequency spectrum;
- a second device configured to use a second frequency spectrum;
- and
- an intermediary device coupled to the first device and the second device, the intermediary device configured to
- receive a first signal having a first frequency of the first frequency spectrum from the first device,
- generate a second signal having a second frequency of the second frequency spectrum from the first device based on the first signal,
- receive scheduling data from the second device, the scheduling data including a time shift, the scheduling data generated based on a Physical Downlink Control Channel (PDCCH) message directly received by the second device from the first device, and
- transmit the second signal to the second device based on the scheduling data.
