Method and device for interpreting of transport format combination indicators
First Claim
1. A communication device comprising a physical layer (L1) and two or more higher layers (L2/L3), said physical layer comprising means to acquire a data modulated waveform signal (3), comprising at least one data block and an indicator of the format of said data block, means to process said block and indicator, in order to be able to map the received block onto a number of transport channels (24,25) in the higher layers, characterized in that said physical layer (L1) comprises:
- a shared memory block (30), wherein lookup tables (35,38) for transport formats (40) and transport format indicators (37) can be saved, allowing the physical layer (L1) to identify transport formats for one or more transport channels, a connection (32) between the physical layer (L1) and the higher layers which allows said lookup tables to be loaded into said shared memory block (30) from the higher layers, a finite state machine (31), capable of acquiring the transport format from the shared memory block (30).

Abstract
The present invention is related to a communication device comprising a physical layer (L1) and two or more higher layers (L2/L3), said physical layer comprising means to acquire a data modulated waveform signal (3), comprising at least one data block and an indicator of the format of said data block, means to process said block and indicator, in order to be able to map the received block onto a number of transport channels (24,25) in the higher layers, characterized in that said physical layer (L1) comprises:
a shared memory block (30), wherein lookup tables (35,38) for transport formats (40) and transport format indicators (37) can be saved, allowing the physical layer (L1) to identify transport formats for one or more transport channels,
a connection (32) between the physical layer (L1) and the higher layers which allows said lookup tables to be loaded into said shared memory block (30) from the higher layers,
a finite state machine (31), capable of acquiring the transport format from the shared memory block (30).

6. A method of processing a data modulated waveform signal (3), comprising the steps of
Receiving by a receiving device, a data modulated waveform signal (3), comprising at least one data block and at least one indicator of the format of said data block, said receiving device comprising a physical layer (L1), and a number of higher layers (L2/L3), transferring said data block over a physical data channel (20), while transferring said indicator over a physical control channel (21), decoding and demultiplexing said data block, in order to map said data block onto at least one transport channel (24,25), decoding said indicator of the format of said data block, resulting into one code (36) for the format of said data block, looking up in a first table (35), an indicator (37) to the format for each transport channel which corresponds to the code (36) for the format of said data block, said first table being present in a shared memory block (30), which is implemented in said physical layer (L1), looking up in a second table (38), all transport formats (40), which correspond to said indicator (37) to the format for each transport channel, said second table being present in said shared memory block (30), which is implemented in said physical layer (L1), mapping said data block onto said at least one transfer channel (24,25), in the correct transport format.
