Thanks for your inputs.
>what exactly is your definition of 'rach_type'? Could you please either add a reference to the document where this notion is >specified, or if there is none, a specification of its value range.
We propose to use following enum as 'rach_type'
GPRS_8_BIT_RACH = 0,
This is not specified in standard, this is introduced as part of proposed interface changes between osmo-bts and osmo-pcu.
Osmo-bts should get the RACH information from L1 APIs and fill the appropriate 'rach_type' and send to osmo-pcu.
Osmo-bts can distinguish between 8 bit RACH and 11 bit RACH using 'u8Size' parameter in PH-RA-IND premetive.
There is still open point on how osmo-bts distinguishes between types of 11 bit RACH based on received layer 1 message.
Let me know if you have any inputs.
