Hello All,

We are currently working on providing the support of 11 bit RACH support  in osmoPCU  as mentioned in Bug #1548  at https://projects.osmocom.org/projects/osmopcu/issues

We have identified  impacts to be in  osmo-pcu, osmo-bts and osmocore

Main changes identified are

osmo-pcu:

· In  file pcuif_proto.h,   modify “uint8_t ra” to “uint16_t ra”   in  struct  gsm_pcu_if_rach_ind

· Corresponding function prototypes due to change in data type

· 11 bit RACH handling in bts.cpp

· Changes in encoding.cpp to support  immediate assignment  with EGPRS allocation

osmocore:

· In file l1sap.h,   modify “uint8_t ra” to “uint16_t ra”  in   structure “struct ph_rach_ind_param”

· Function prototype changes

osmobts:

· Function prototype changes due to change in data type

Please let us know your valuable feedback.

We plan to  have a separate branch from master for this development. Please let us know the procedure to do this.

Regards

Prasad
