Abstract
A wireless communication system includes a plurality of communication devices. The RF transceiver includes a transmitter and a plurality of receivers, each receiving signal from an associated communication device. A Enhanced Node B (eNB) can communicate with a plurality of communication devices in a Multiple-Input Multiple-Output (MIMO) system. The Node B includes a transmitter and plurality of antenna configured to transmit control information. The wireless communication system may utilize licensed and unlicensed RF spectrum. Long Term Evolution (LTE) is transmitted according to licensed and unlicensed spectrum. The invention deals with swapping between primary carrier and secondary carrier(s) for licensed and unlicensed spectrum.
Claims15
A wireless communication method in a UE comprising:
- measuring a network signal strength;
- sending a measurement report;
- and
- receiving a report to inform a serving cell of an interference capability of the UE and of measurements of signals received by the UE from the serving cell and a neighbor cell.
A method of measuring interference capability comprising:
- transmitting a measurement for load capabilities and DL measurements;
- receiving a request to report load capabilities and a measurement parameter;
- determining the measurement parameter;
- and
- generating and transmitting a report, wherein load capabilities and the measurement parameter is reported.
A wireless communication system comprising:
- a primary carrier capable of controlling signaling, mobility, and user data;
- a secondary carrier capable of providing best effort user data in downlink;
- wherein a licensed and an unlicensed carrier between the primary carrier and the secondary carrier can be swapped for a UE.
A wireless communication system comprising:
- a multi-mode UE haying a processor configured to promote measurements of a signal strength in the wireless communication system and run an application that increasingly demands higher data rates;
- a primary component carrier, wherein the primary component carrier is a main carrier and is one of a licensed carrier and an unlicensed carrier;
- a secondary component, wherein the secondary component is a secondary carrier and is one of a licensed carrier and an unlicensed carrier;
- wherein the multi-mode UE determines the primary component carrier according to loading on the carriers;
- and
- wherein the multi-mode UE swaps between a licensed carrier and an unlicensed carrier.
