Abstract: Systems, methods, apparatuses, and computer program products for reducing latency in 5G/NR are provided. One method may include determining, by a network node, to apply selective reordering of one or more data units received at a user equipment, and indicating the decision to apply selective reordering to the user equipment. The selective reordering temporarily alters packet data convergence protocol window behaviour in the user equipment such that a packet data convergence protocol layer in the user equipment is caused to deliver, to upper layer(s), the stored data units with an associated count value that is less than the count value associated with a data unit at the user equipment and/or the stored data units with consecutively associated count values starting from the count value associated with a data unit at the user equipment.

Abstract: While a transmission time interval (TTI) length of other than 1 ms is in effect for communication between mobile and network nodes, at least one timer related to discontinuous reception (DRX) is implemented according to a rule that defines a time duration of the timer different from a time duration of the same timer implemented when the TTI length is defined as 1 ms. There are a plurality of such DRX-related timers, and in certain embodiments each is associated with one rule of a set of rules for implementing the respective timer when the TTI length is other than 1 ms; and in particular examples the timers are associated with groups for this purpose and all the timers of at least one of the groups is implemented according to the same rule of the set. Thus new DRX parameters need not be sent anytime the TTI length changes.
