Signaling Method To Enable Controlled TX Deferring In Mixed License and Unlicensed Spectrum In Carrier Aggregation In Future LTE-A Networks
First Claim
1. A method, comprising:
- establishing a connection between a User Equipment (UE) and a base station (eNB) utilizing licensed and unlicensed frequency bands;
generating a transmission deferring indication regarding a first component carrier locating on an unlicensed band, in case the first component carrier is occupied; and
deactivating data transmission on the first component carrier according to the transmission deferring indication for deferring the data transmission on the first component carrier.

Abstract
The present invention discloses a signaling method, an apparatus and a computer program for controlled transmission signal deferring utilizing both licensed and unlicensed frequency bands for carrier aggregation. In the method, a connection is established between a User Equipment and a base station. For example, based on a sensed interference level, a transmission deferring indication is generated regarding a secondary component carrier locating on an unlicensed band, in case the secondary component carrier is occupied. This indication may be generated and sent either by the base station or by the User Equipment. Finally, the secondary component carrier is deactivated for data transmission, for deferring data transmission for a certain time period. After the deferring time has passed, the data transmission can be re-performed on the same secondary component carrier, or through switching to another secondary component carrier in unlicensed spectrum.
