( https://gerrit.osmocom.org/c/osmo-bts/+/29578 ) Change subject: osmo-bts-trx: handle MTS 0b0110 indicating an Access Burst ...................................................................... Patch Set 1: (1 comment) Patchset: PS1: Because the BTS has no access to the internal scheduler state of the PCU. Only the PCU knows that a particular PDCH block is expected to be received in form of four Access Bursts instead of Normal Bursts, because it's the PCU who polls the MS. Given the dynamic nature of PDCH, the BTS cannot make assumptions on whether an Uplink block is a PACKET_CONTROL_ACK or not. We could introduce some special PCUIF message indicating that N-th block is going to be in form of Access Bursts, but given the scheduling advance (i.e. latency between UL and DL) I think it would be hard to make this work reliably. SI13 contains the default value, which can be overridden in the polling message. -- To view, visit https://gerrit.osmocom.org/c/osmo-bts/+/29578 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bts Gerrit-Branch: master Gerrit-Change-Id: I0fbb63006797e6be386d1f76ed97fff098c036fc Gerrit-Change-Number: 29578 Gerrit-PatchSet: 1 Gerrit-Owner: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Tue, 04 Oct 2022 16:11:35 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
