Abstract
A multi radio access technology layer (MRL) is a convergence layer solution, located between the protocol layers and the technology-dependent MAC layers. The MRL layer is technology independent and uses the information received from the underlying technologies to select the most appropriate uplink and downlink technologies to match the respective service requirements.
Claims8
A method of multi radio access technology (multi-RAT) communication, the method comprising:
- receiving, at a multi radio access technology layer (MRL) entity, a PDCP data packet -via a first physical (PHY) layer type, a first data packet of a first protocol type;
- determining from the received PDCP data packet whether the PDCP data packet is an LTE data packet or a Wi-Fi data packet;
- encapsulating, at the MRL entity, the first PCDP data packet of the first protocol type in a MAC data packet if the PCDP data packet is an LTE data packet of the second protocol type, wherein the first protocol type and the second protocol type are not a same protocol type;
- and
- transmitting, from the MRL entity via a second PHY layer type, the encapsulated MAC data packet via an LTE protocol with an LTE control message of the second protocol type, wherein the first PHY layer type and the second PHY layer type are not a same PHY layer type.

A radio base station comprising:
- a processor configured to:
- communicate via a multi radio access technology layer (MRL) to receive, via the MRL a PDCP data packet;
- determine from the received PDCP data packet whether the PDCP data packet is an LTE data packet or a Wi-Fi data packet;
- encapsulate the PCDP data packet in a MAC data packet if the PCDP data packet is an LTE data packet;
- and
- transmit the encapsulated MAC data packet via an LTE protocol with an LTE control message.
