A method of flow control performed by a primary Radio Link Control, RLC, entity operating at an RLC protocol layer in a wireless communication network , the primary RLC entity implemented by a processing apparatus (18-1) and the method comprising: receiving RLC Service Data Units, SDUs, incoming from a Packet Data Convergence Protocol, PDCP, entity operating at a PDCP protocol layer in the wireless communication network , the RLC SDUs carrying user traffic for a User Equipment, UE, ; providing respective shares of the RLC SDUs, or RLC Protocol Data Units, PDUs, formed therefrom, to two or more Downlink, DL, connections that communicatively couple the wireless communication network to the UE , each DL connection including one or more radio links and having an associated secondary RLC entity that provides RLC PDU segmentation, as needed, for RLC PDU transmissions on the one or more radio links ; and dynamically determining the respective shares in dependence on feedback received at the primary RLC entity for the two or more DL connections , the feedback relating to throughputs of the two or more DL connections , wherein: each of the two or more DL connections is associated with one or more Medium Access Control, MAC, entities operating at a MAC protocol layer in the wireless communication network , each MAC entity providing MAC-layer processing for one or more of the one or more radio links included in the DL connection ; and the one or more MAC entities associated with the respective DL connections exchange MAC-related signaling that experiences delay; and a control interval used by the primary RLC entity for dynamically determining the respective shares accounts for the delay. receiving RLC Service Data Units, SDUs, incoming from a Packet Data Convergence Protocol, PDCP, entity operating at a PDCP protocol layer in the wireless communication network , the RLC SDUs carrying user traffic for a User Equipment, UE, ; providing respective shares of the RLC SDUs, or RLC Protocol Data Units, PDUs, formed therefrom, to two or more Downlink, DL, connections that communicatively couple the wireless communication network to the UE , each DL connection including one or more radio links and having an associated secondary RLC entity that provides RLC PDU segmentation, as needed, for RLC PDU transmissions on the one or more radio links ; and dynamically determining the respective shares in dependence on feedback received at the primary RLC entity for the two or more DL connections , the feedback relating to throughputs of the two or more DL connections , wherein: each of the two or more DL connections is associated with one or more Medium Access Control, MAC, entities operating at a MAC protocol layer in the wireless communication network , each MAC entity providing MAC-layer processing for one or more of the one or more radio links included in the DL connection ; and the one or more MAC entities associated with the respective DL connections exchange MAC-related signaling that experiences delay; and a control interval used by the primary RLC entity for dynamically determining the respective shares accounts for the delay. each of the two or more DL connections is associated with one or more Medium Access Control, MAC, entities operating at a MAC protocol layer in the wireless communication network , each MAC entity providing MAC-layer processing for one or more of the one or more radio links included in the DL connection ; and the one or more MAC entities associated with the respective DL connections exchange MAC-related signaling that experiences delay; and a control interval used by the primary RLC entity for dynamically determining the respective shares accounts for the delay. <EOS>
