pespin gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-pcu/+/23520 to look at the new patch set (#2). Change subject: Pick unreserved UL FN when allocating an SBA ...................................................................... Pick unreserved UL FN when allocating an SBA Make sure an unreserved FN is picked and reserved when allocating and scheduling an SBA. In practice this has no change in behavior right now, since anyway using an offset of 52 FNs ensure no USF or POLL has alredy been scheduled that far in the future. Since it's also impossible to allocate more than 1 SBA per PDCH and RTS FN, we are also safe about multiple SBAs being allocated, because we use a hardcoded offset of 52. However, that could change in the future, when we dynamically tweak the current offset of 52 FN based on information from BTS about its AGCH queue load: * If load is high, we may need to increase the offset since it will take more time for the BTS to transmit the TBF and hence we must reserve a TBF starting time further in the future (higher FN). * If load turns low, we may schedule next SBA a bit more nearby in time than the previously allocated SBA, hence here there could be a collision.
