2016-02-05edge: Support MCS data block encodingJacob Erlbeck1-0/+243
Currently only GPRS data block encoding is supported. This commit adds rlc_data_to_dl_append_egprs which does the EGPRS specific extension and chunk handling. It extends Encoding::rlc_data_to_dl_append to use that function for MCS coding schemes. Sponsored-by: On-Waves ehf
2016-02-05edge: Select implementation by mode in rlc_data_to_dl_appendJacob Erlbeck1-13/+13
Currently the GPRS data block encoding is applied to every coding scheme, even if an MCS is selected. This commit renames the actual encoding function to rlc_data_to_dl_append_gprs (not exported) and puts selection code into Encoding::rlc_data_to_dl_append. This requires an additional cs argument.

2016-02-05edge: Add Encoding::rlc_data_to_dl_appendJacob Erlbeck2-0/+253
This function appends a single chunk to an RLC downlink data block. The implementation is basically taken from the gprs_rlcmac_dl_tbf::create_new_bsn method without the TBF related functionality and any side effects. Note that it still only supports GRPS. Sponsored-by: On-Waves ehf
2016-02-05edge: Add encoder for downlink RLC data blocksJacob Erlbeck1-0/+70
Currently the (GPRS) RLC block encoding is done by setting the header fields directly in gprs_rlcmac_dl_tbf::create_new_bsn. This is much more complex with EGPRS, since the data fields are not byte aligned, the header formats depend on the header type, and the mapping of bits to bytes is LSB first. This commit adds Encoding::rlc_write_dl_data_header which writes the header according to the given gprs_rlc_data_header structure. Encoding::rlc_copy_from_aligned_buffer is also added to copy byte sequences into the message. Note that the actual encoding of data units is not yet present. Sponsored-by: On-Waves ehf
2016-02-05edge: Add init functions for gprs_rlc_data_infoJacob Erlbeck2-0/+20
Add the functions gprs_rlc_data_info_init_dl/ul which initialise a gprs_rlc_data_info structure depending on the coding scheme. The fields num_data_blocks, data_offs_bits, cs, and the data_blocks are valid after this call. The other fields are set to 0. The data blocks are initialised to the correct data_len, e == 1 (no extension header field), cv == 15 (not a final block). The other data block fields are set to 0. The gprs_rlc_data_block_info can also be initialised separately by using the gprs_rlc_data_block_info_init function. Sponsored-by: On-Waves ehf
2016-02-05edge: Fix RLC message sizeJacob Erlbeck1-4/+4
Currently the RLC message length that is obtained from the DSP is reduced by 1 if the last byte of the buffer includes spare bits. While this worked well with GPRS, these bits are being used to encode RLC blocks in EGPRS mode. Thus this last byte must not be chopped off. The functionality of the code is not affected by this, since the modified length value is not used. This commit adds GprsCodingScheme::usedSizeDL/UL to return the number of bytes needed to encode the message block. If there are single bits at the end that are to be used (EGPRS), the functions return the number of full bytes plus 1 (which is the buffer size reported by the DSP and returned by sizeUL/sizeDL). The commit also removes the len parameter from rcv_data_block_acknowledged. Sponsored-by: On-Waves ehf
2016-02-05edge: Rename gprs_rlc_ul_header_egprs and gprs_rlc_ul_data_block_infoJacob Erlbeck1-1/+1
These struct names are more specific than necessary. They are used for GPRS (uplink) already. In downlink direction, only a few fields will be added to the header struct. Add addition, gprs_rlc_ul_header_egprs does not map directly to an encoded header, like many other 'header' structs do. Change the names to fit both modes and both directions: gprs_rlc_ul_header_egprs -> gprs_rlc_data_info gprs_rlc_ul_data_block_info -> gprs_rlc_data_block_info Sponsored-by: On-Waves ehf
2016-02-01edge: Add methods and operators to GprsCodingSchemeJacob Erlbeck1-3/+4
Add a few new operators and methods to support the use of GprsCodingScheme instead of the plain integer currently used. Sponsored-by: On-Waves ehf
2016-02-01edge/test: Rename test_rlc_decoder to test_rlc_unit_decoderJacob Erlbeck2-4/+4
This test only covers RLC data units and not whole RLC messages. Sponsored-by: On-Waves ehf
2015-12-16edge: Add test cases for rlc_data_from_ul_dataJacob Erlbeck2-0/+314
This checks the example test cases given in appendix B of TS 44.060. Sponsored-by: On-Waves ehf
2015-12-15edge: Add information about data blocks to GprsCodingSchemeJacob Erlbeck1-0/+4
This commit adds the methods maxDataBlockBytes and numDataBlocks which provide information about the data areas within RLC messages. In these areas, the extension bytes, TLLI, and the LLC data are stored. Sponsored-by: On-Waves ehf
2015-12-15edge: Add header type property to GprsCodingSchemeJacob Erlbeck1-0/+6
The header type depends on the coding scheme, for GPRS there is a single data header type per direction, for EGPRS there are 3 per direction. In addition, control block header types are used with CS-1 only, so there is one of the per direction altogether for GRPS and EGPRS. This commit adds the header type enum and two methods headerTypeData and headerTypeControl. Sponsored-by: On-Waves ehf

This test checks constructors, predicates, and operators of the GprsCodingScheme class. Sponsored-by: On-Waves ehf
