WebApr 5, 2024 · Unlike LTE, HARQ re-transmissions are asynchronous in 5G NR uplink direction. When an UL transport block is erroneously received (CRC error) by the gNodeB, the UE may be asked to re-transmit the same packet. The UE would miss the re-transmission request (grant) from the gNodeB if it is not in active state at the time of re-transmission request.

WebAbstract—In this paper, we use a New Radio (NR) simulator, based on ns-3, to assess the impact of 5G NR numerologies on the end-to-end (E2E) latencies in a realistic and complex scenario, including TCP and UDP flows. As expected, we found that TCP goodput increases with the numerology, since a larger numerology allows reducing the round-trip ...

WebFeb 8, 2024 · When UE is in RRC_IDLE or RRC_INACTIVE, request for OSI will trigger a random access procedure. UE will read SI scheduling information from SIB1 and UE will determine the broadcast status from “si-BroadcastStatus” for an SI message. If “si-BroadcastStatus” is “broadcasting”, the UE would acquire the required SIB normally. WebUCI (Uplink Control Information) is carried by PUCCH channel in 5G NR. UCI consists of HARQ (Hybrid Automatic Repeat Request) feedback, CSI (Channel State Information) and SR (Scheduling Request). Refer 5G NR PUCCH >> for more information.
