Method and apparatus for transmitting layers for scalable data services

摘要

The present invention relates to a radio access network and a communication method in a wireless system comprising a radio access network and a plurality of mobile terminals. To enable a user terminal to carry out inter-frequency measurements without additional significant requirements on processing time, the RAN notifies a mobile terminal to perform inter-frequency measurements, transmits transmission data of a scalable data service to the mobile terminal, wherein the transmission data comprises a plurality of importance layers, and schedules the importance layers of the transmission data, wherein the scheduling comprises selecting a subset of the plurality of importance layers for transmission.
