  • METHODS AND APPARATUSES FOR SKIPPING TRANSPORT BLOCK TRANSMISSION DEPENDING ON UPLINK CONTROL INFORMATION TRANSMISSION
    Publication number: 20190200381
    Abstract: Systems, methods, apparatuses, and computer program products for skipping TB transmission depending on UCI transmission are provided. One method includes receiving, by a UE, a configuration message from a network node. The configuration message may indicate to the UE a configuration of skipping uplink (UL) transmission when there is no uplink data. The method may then include determining whether the UE is requested for uplink control information (UCI) transmission for a subframe with UL grant. If it is determined that the UE is requested for UCI transmission, then the method may include generating and transmitting a transport block containing padding buffer status report (BSR).

  • DISCONTINUOUS RECEPTION TIMER OPERATION FOR CHANGED TTI LENGTH
    Publication number: 20190045440
    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.
