Abstract: Described are methods, systems and devices for eliminating redundant retransmissions in radio link layer (RLC) acknowledged mode (AM) data transmissions and receptions. In some embodiments, when an RLC service data unit (SDU) has not been completely received, the value of a state variable may be selectively set based on whether or not a contiguous set of byte segments of the RLC SDU have been received. This prevents the retransmission of byte segments that are either currently being transmitted or have not yet been transmitted. In other embodiments, the selective setting of the state variable may be triggered by the expiration of a reassembly timer. The described implementations may improve the data transmission of RLC SDUs in high data rate scenarios, which may be ubiquitous in 5G implementations.

Abstract: The invention describes a method and a computer network for fault tolerant message transmission. Nodes of the network are connected to form a ring network. Nodes in the network form a summation group. For transmitting messages from the nodes of the summation group to a switch edge, nodes of the summation group generate and send summation frames. If a node participating in the summation group determines the non-arrival of a summation frame, it generates first recovery frame, inserts its message into said recovery frame, and sends this first recovery frame in the direction of the summation frame, which it was expecting. After sending the first recovery frame, it generates a second recovery frame, inserts its messages into said second right direction recovery frame, and sends said second right direction recovery frame to the switch.
