<ul></ul><p>It is seen that, <abbr title="May be all Nokia, May be other MS as well">E52</abbr> asks RLC UL MODE as UM. And there is no IE to indicate the RLC mode for UL in prior rel6 versions in Packet UL assignment. But PCU currently supports only AM mode. so there is out of sync between RLC mode at MS and PCU. With this, even if 1 RLC block needs to be re transmitted from MS, PCU waits indefinitely. But MS keeps sending only fresh RLC blocks. and PCU keeps printing "out of window". and we see data break at end to end testing(using Iperf).</p>
<p>So with this analysis, we conclude it is mandatory to support RLC UM mode at least for UL direction. In our testing we have also seen that, we can have different RLC mode for UL and DL direction.</p> OsmoPCU - Bug #1838: Nokia E52 doest reply to PUAN message properlyhttps://projects.osmocom.org/issues/1838?journal_id=26332016-12-16T10:08:56Zarvind.sirsikar
