profile0x0000

Asked by regulararmy

Dear Didier:
    In the codes of library, there is profile0x0000, however,there is no 0x0000 profile mentioned in the LTE 36.331 protocol document for RRC.
    if I make use of your codes in a realization of soft production, the RRC layer firstly must configure the profile parameters for lower layer,however,there is no 0x0000 according to the LTE 36.331.so,what can I do for that? I wonder if no configuration means profile0x0000 in your code,please.

Regards

The 0x0000 profile is defined in RFC3065. It is the Uncompressed profile.

If you don't want the Uncompressed (0x0000) profile, do not enable it. For example in the simple_rohc_program [1], remove the call to:
  rohc_activate_profile(compressor, ROHC_PROFILE_UNCOMPRESSED);

Didier
