Disclosed is a method comprising obtaining a reliability estimate indicating transmission success probability for a plurality of transmission legs and assigning a data packet type to a subset of the plurality of transmission legs based at least partly on said reliability estimate.

Leg selection for improved reliability of multi-connectivity

Disclosed are two methods, the first method comprising receiving a plurality of data packets, producing a coded data packet by coding together at least two data packets, wherein at least one of the at least two data packets is comprised in the received plurality of data packets or in a coding buffer, transmitting the at least two data packets to a first subset of legs, transmitting the coded data packets to a second subset of legs, and determining if the at least two data packets are to be duplicated based on, at least partly, one or more of the following: a notification, a condition, or a first indication. The second disclosed method comprises receiving a data packet and an indication of a coding function and parameters used for coding two or more data packets, determining if the received data packet is a coded data packet and if it is, determine if one or more internal buffers comprise a minimum set of data packets for generating the coded data packet, using sequence numbers assigned to each data packet, and if the one or more internal buffers comprise the minimum set of data packets, retrieve the minimum set of data packets from the one or more internal buffers, and decoding the coded data packet using the minimum set of data packets and the coding function and parameters indicated by the indication received.

Reliability of multi-connectivity

Systems, methods, apparatuses, and computer program products for real-time uplink (UL) power control are provided. One method may include estimating, by a network node, a power allocation function for determining power allocation across a plurality of legs that transmit simultaneously, the power allocation function being based on radio channel statistics and network performance metrics. The method may then include signaling, to a user equipment, the power allocation function and the parameters used to compute an output of the power allocation function.
