Abstract: Systems and methods of reducing control plane latency in a 5G IAB network are described. SRs transmitted between nodes indicate that a control plane PDU is to be transmitted. The SRs use periodic resources or OCCs reserved for control plane signaling and are initiated by an RRC message or RACH from the UE. The SRs are initiated if the LCD field in the MAC subheader of the RRC message indicates the CCCH or the DCCH logical channel. If the PDU is available after the original resource, a resource is used that is provided via another grant, which is periodically provided or automatically initiated due to failure to transmit on the original grant. The SR or RRC message can also specify a delayed timeslot for the grant. For contention-based procedures the RACH preamble is randomly selected or selected from among a set of RACH preambles assigned for RRC procedures.

Abstract: Various embodiments herein relate to techniques for ultra-reliable and low latency communication (URLLC) in wireless cellular networks. For example, embodiments include hybrid automatic repeat request (HARQ) enhancements for URLLC. Additionally, embodiments include techniques for determining a HARQ identifier (ID) for multi-transport block (TB) transmissions, such as multi-TB configured grant transmissions and/or multi-TB transmissions in unlicensed spectrum.

Abstract: An apparatus and system for reducing URLLC latency are described. A single packet mode is described in which, when a packet arrives at the PDCP layer for transmission, an indication is sent to a scheduler with the expected size of the packet after ciphering. The packet is then sent to the RLC layer and concurrently submitted to the ciphering engine to enable ciphering to occur in parallel with the other activities. The scheduler determines the expected TB size for transmission of the packet by determining the size of the PDCP, MAC, and RLC headers. The scheduler matches the resource allocation for transmission to the expected TB size.

Abstract: Systems and methods of providing uplink in-order packet delivery of a QoS flow offloaded in a 5G network are described. An uplink forwarding tunnel is established between a source and target node after a determination is made to offload a QoS flow of a UE to the target node. The source node receives a SDAP PDU from the UE that contains an end marker and, in response, sends a GTP-U end marker packet to the target node via the uplink forwarding tunnel. The target node buffer packets associated with the QoS flow received from the UE after establishment of the uplink forwarding tunnel until the GTP-U end marker packet is received from the target node via the uplink forwarding tunnel and, in response, sends the buffered packets to the 5GC.

The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has San offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

Abstract: A method for low overhead system information acquisition (LOSIA) is disclosed. The LOSIA method includes several techniques for transmitting common channels in a next generation Radio Access Technology (xRAT). Instead of transmitting system information in a periodic, static, cell-specific, wideband manner, the transmission is triggered by user equipment in an “on demand” manner. The LOSIA method allows the network to control the overhead, bandwidth, and periodicity, as well as other characteristics. The LOSIA method employs several different techniques to trigger the information upon which the network can act, for example, by transmitting different payloads depending on the received trigger.

In another embodiment, only one node provides the reporting configuration but configures the UE to provide reporting to one node or both MN and SN.
