Method and device for handling data in certain layers according to certain protocols in a mobile communications system

摘要

The scope of the present invention is a method for data transfer in a digital mobile communications system, in which method it is handled data in certain layers according to certain protocols, in a certain layer out of said layers it is transferred user data in radio blocks (RB) over a physical radio channel between a mobile station and a fixed mobile communications network, for the transfer of said certain layer it is formed in the radio block (RB) a payload of a certain size comprising check bits (CHB) connected with the performing of the transfer and transfer bits (TB) available for the transfer of user data, each radio block (RB) is channel coded using a certain coding method and the size of said payload is dependent on the coding method. In the transfer bits (TB) of the radio block to be coded using at least a certain coding method it is transferred user data in a first part of the transfer bits and in a second part of the transfer bits it is transferred fill bits in such a way that it is chosen for the transfer of user data a number of transfer bits divisible by eight.
