Problems solved by technology

[0012] Given this maximum number of bits, a short code sequence can be used for the encoding of these bits, but the consequence of this is that data is lost during transmission
[0013] Whereas if a long code sequence and coded bits are used and then divided according to "chunks", then it is very difficult to find a suitable code length for the respective modulation
Independent coordination of coding on the one hand and adaptively adjustable modulation on the other hand can only be very difficult for the required optimal efficient data transmission

Embodiment Construction

[0024] The two data blocks DP2 and DP3 of the third layer are merged into a data block DP23 as a link layer data block on the second layer, and the data block DP1 of the third layer reaches the second layer as a data block DP11.

[0025] The data block DP11 has a header RB11 and the data block DP23 has a header RB23, where each header RB11, RB23 contains its own CRC code and control information.

[0026] The data block DP11 and the header RB11 are jointly externally coded, and the data block DP23 and the header RB23 are jointly externally coded. The external code is selected in consideration of the service quality requirements and the selected communication level.

[0027] For external coding, if the code length assigned to a "chunk" is suitable for meeting the error correction requirements of the observed data packet, for example, ordinary error correction codes can also be used.

[0028] Through external coding, a new data block DP111 is formed by the data block DP11 and the header ...

Abstract

The present invention relates to a method for encoding data blocks for transferring to a radiocommunications system consisting in encoding at least one data block according to predetermined quality-of-service requirements with the aid of a first code and in subsequently encoding said encoded by the first code data block according to the radio transmission properties of a usable radiotransmission source with the aid of a second code.

Description

Technical field [0001] The invention relates to a method for encoding data blocks for transmission on a radio communication system. Background technique [0002] In the third and fourth generation mobile communication networks, the so-called "multi-carrier" transmission method that modulates multiple carriers at the same time is becoming increasingly important. A typical multi-carrier transmission method is the so-called "Orthogo- [0003] Nal Frequency Division Multiplexing, OFDM"-a radio transmission method in which a carrier called "Subcarrier" is used to transmit symbols. The advantage of the multi-carrier transmission method is high data transmission rate at low reception costs. In addition, The fluctuations in time relative to the characteristics of the radio transmission channel are very robust. [0004] In a large number of radio transmission methods (also included in OFDM radio transmission) radio transmission resources called so-called "chunks" are used. A "chunk" determ...
