Abstract
A method performed by a network node for retransmitting a Radio Link Control, Protocol Data Unit (RLC PDU), to a UE is provided. The UE and the network node operate in a wireless communications network. The UE is configured to use Discontinuous Reception (DRX). When an RLC PDU transmitted to the UE is indicated to not being received by the UE, the network node determines (601) a time until a first DRX on-duration time period that is possible to allow time for Hybrid Automatic Repeat Request (HARQ) operations to complete a retransmission of a Medium Access Control (MAC) PDU. The MAC PDU is associated to the RLC PDU. The network node then initiates a retransmission (603) of the RLC PDU to the UE according to the determined time.
