Inheritance in sample array multitree subdivision
A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks.

Rather, similarities may effectively exploited by using the multitree subdivision. |

Multi-view coding with effective handling of renderable portions
A proposed intermediate way of handling the renderable portion of the first view results in more efficient coding. Instead of omitting the coding of the renderable portion completely, even more efficient coding of multi-view signals entails merely suppressing the coding of the residual signal within the renderable portion, whereas the prediction parameter coding still takes place from the non-renderable portion of the multi-view signal across the renderable portion so that prediction parameters for the renderable portion may be exploited for predicting parameters for the non-renderable portion. The additional coding rate for transmitting the prediction parameters for the renderable portion may be kept low as this merely aims at forming a continuation of the parameter history across the renderable portion to serve as a basis for prediction parameters of other portions of the multi-view signal. Expressed differently, the prediction parameters for the renderable portion need not perfectly predict the texture within the renderable portion of the first view to keep the residual signal within the renderable portion low. |

Synchronization in mixed OFDM sub-carrier spacing scenarios
A wireless communication device receives OFDM radio signals having different numerologies (i.e. different sub-carrier spacing) and determines whether the transmission, by one or more transmitting nodes, of the OFDM signals are coordinated. The meaning of “coordinated” is to be understood as the OFDM signals are time-synchronized and the determination of whether the OFDM signals are coordinated may involve such actions as reading broadcast or receiving configuration message transmitted in the system, determining a relation (for instance cell/access point beam identity) between transmitted synchronization or reference signals. If the OFDM signals are determined to be coordinated, time and/or frequency offset for the second OFDM signal having the second subcarrier spacing is derived based on the time and/or frequency offset associated with the first OFDM signal having the first subcarrier spacing. |
