All the issues can be tracked under milestone, https://gitlab.eurecom.fr/oai/openairinterface5g/milestones/7
|
|
|
|
|
|
* PUCCH issues -> RK: **L1L2 signalling issue**, https://gitlab.eurecom.fr/oai/openairinterface5g/issues/48
|
|
|
* SR not detected well / falsly detected -> improved (commited in L1L2 signalling branch)
|
|
|
* Power control: RK is testing and making changes in L1L2 signalling branch
|
|
|
* UL scheduling: **L1L2 signalling issue**, https://gitlab.eurecom.fr/oai/openairinterface5g/issues/48
|
|
|
* very low/fluctuating throughput
|
|
|
* PUSCH never decoded in first or second round for all (possible) PRB
|
|
|
sizes between 24 and 45. 48 works again. no problems in ulsim though. -> FK
|
|
|
* check BSR
|
|
|
* format0 retransmissions (works better when turned off)
|
|
|
* all subframes activated
|
|
|
* bugs in CQI reporting in 10Mhz (no. subbands)
|
|
|
* MAC CE only sent when there is DL traffic
|
|
|
* Find cause of "other failure" -> RK
|
|
|
* this is a radio link failure of UL, when the UE cannot get the UL (for example when SR is not received)
|
|
|
* Failures leading to ConnectionReestablishment (milestone: Conn reestablish procedures) (NN to look into this)
|
|
|
* We send ReestablishmentReject, this will lead to a re-attach using STMSI
|
|
|
* Current workaround: We send ReestablishmentReject, this will lead to a re-attach using STMSI, but only after a very long time
|
|
|
* UE removal (L1/Partial-L2): NN (L1/L2/L3)
|
|
|
* UE removal from failed PRACH/MSG3 L1/L2 Connection procedure ok
|
|
|
* UE removal from RRC not ok (RRCConnectionRelease), does not remove
|
|
|
lower layers (for all the layers of eNB)
|
|
|
* Attach procedure using STMSI -> **(This is very critical issue. Lot of UEs do not work
|
|
|
because of this behaviour). Navid/Lionel wants to take a look.**
|
|
|
* eNB should not drop UE after 10 errors, at least not in MAC. PHY can drop it, but MAC need to reconfigure PHY once UE sends CRNTI CE
|
|
|
* Raymond already included an activity timer and a connection timer (instead of the consecutive error count). only when that is reached, UE is remove from MAC.
|
|
|
* Attach procedure using STMSI -> **(This is very critical issue. Lot of UEs do not work because of this behaviour). Navid/Lionel wants to take a look.**
|
|
|
* need to keep UE context in RRC until timer expires
|
|
|
* to be decided: shall eNB keep context even when it crashes? i.e. in a file?
|
|
|
* check if we can send ConnectionReject. Does that have any other side effects on UE? Lets just try it!
|
|
|
* Part of the fix is already applied
|
|
|
* TM2 (L1)
|
|
|
* Most things fixed, but more testing needed (USRP ok 5/10MHz, ExpressMIMO2 tbc)
|
|
|
* No available CCE resources for UE: **L1L2 signalling issue**
|
|
|
* fixed in L1/L2 branch (https://gitlab.eurecom.fr/oai/openairinterface5g/issues/48)
|
|
|
* this branch should be merged back to develop soon
|
|
|
* UE drops the connection and comes back with S-TMSI.
|
|
|
* Timing advance issue (L1L2 signalling has a fix)
|
|
|
|
|
|
## Fixed
|
|
|
|
|
|
* RLC AM has issues -> issue 65 -> fixed in branch, but not yet merged
|
|
|
* CAT 3 UE has throughput issues: This issue has been fixed an merged.
