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.

A method, apparatus and computer program product are provided facilitating flexible time sharing among systems. A method and apparatus may generate a secondary component carrier transmission plan including planned on and off durations.

The planned off durations correspond to a time interval in which the devices may deactivate from the unlicensed band or remain disconnected from the unlicensed band. The method and apparatus may also enable provision of the plan to the devices via a licensed band of a primary component carrier and detecting a medium of the unlicensed band prior to the expiration of the time period to determine whether the medium is available in order to decide whether to turn on transmissions to the unlicensed band after one of the planned off durations.

Innovations in intra block copy ('BC') prediction facilitate handling of special cases when chroma blocks are merged for purposes of the intra BC prediction. For example, encoding includes intra BC prediction for a set of adjacent units (e.g., prediction units of a coding unit).

The encoding includes special case handling for any derived BV value referencing sample values outside a boundary (e.g., picture boundary, slice boundary, tile boundary). The special case handling can use constraints on values of the BVs, clipping of the derived BV value, or padding of sample values at the boundary. In some implementations, corresponding decoding includes special case handling.
