Abstract: This disclosure provides techniques for recovery techniques to address link failure in multi-hop backhaul relay network. For example, a central unit (CU) node receives, uplink transmissions originating from a user equipment (UE) via a backhaul relay including a first distributed unit (DU) node and a second DU node. The CU then receives a first UL status message associated with a link failure between the first DU node the second DU node. Then the CU generates a second UL status message indicating a sequence number (SN) of a lost packet caused by the link failure or a SN of a last successfully received packet before the link failure, and transmits the second UL status message to the first DU node.

Abstract: A next generation NodeB (gNB) implements a radio access network (RAN) convergence functionality for new radio (NR) and wireless local area network (WLAN) access, the gNB further implementing a split architecture comprising a central unit (CU) and a distributed unit (DU) for each of the NR access and WLAN access. The gNB receives a data packet for transmission to a user equipment (UE) implementing the RAN convergence functionality, the data packet comprising one of a control plane (CP) packet or a user plane (UP) packet. The gNB splits the data packet via a convergence layer residing on the NR CU or a convergence layer residing on the WLAN CU and transmits the split data packet over the NR access and the WLAN access.

Abstract: There is provided a base station comprising a data storage device configured to store data corresponding to a first codebook and a second codebook. The first codebook being different from the second codebook. The base station also comprising one or more processors configured to precode reference signals to be transmitted to a user equipment (UE) and precode, using the second codebook, data streams on a common resource element to prevent the data streams from interfering with each other.
