Patch Set 3: (5 comments) Commit Message: https://gerrit.osmocom.org/c/osmo-pcu/+/31145/comment/d194fa9d_ead8e5e1 PS3, Line 11: and the BSC also must instruct the BTS to transmit the via PCH instead of "to transmit the via PCH" transmit the what? https://gerrit.osmocom.org/c/osmo-pcu/+/31145/comment/27ae5f07_7bf71751 PS3, Line 14: This commit description seems to be saying that the fact that the DL TBF Imm Ass is sent over PDCH is ericsson specific. But it is actually not. Patchset: PS3: I am fine with keeping the 2 messages right now, but we should probably try to deprecate and eventually get rid of one of them (the one without TLLI?). We could even add a different primitive with specific uint16_t prgroup and uint32_t tlli fields to it.
