Patch Set 3: (1 comment) Commit Message: https://gerrit.osmocom.org/c/osmo-bts/+/33829/comment/beda57bc_479483c1 PS3, Line 12: Even though it would work to : use the paging group 0, it is more appropriate to send the IMMEDIATE : ASSIGNMENT through the AGCH then. > So again (asking to understand better), what do we win by sending DL TBF assignment over AGCH instea […] The assignment is potentially scheduled/transmitted a lot quicker to the MS, meaning the latency to transmit first packets to it goes down. Furthermore, we reduce the congestion on PCH for paging group 0. -- To view, visit https://gerrit.osmocom.org/c/osmo-bts/+/33829 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bts Gerrit-Branch: master Gerrit-Change-Id: Iaa3e5cdcf86578821e149b3e23482a0bcee19f7b Gerrit-Change-Number: 33829 Gerrit-PatchSet: 3 Gerrit-Owner: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-Attention: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: dexter <pmaier(a)sysmocom.de> Gerrit-Comment-Date: Sun, 23 Jul 2023 16:02:50 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-MessageType: comment
