According to the present invention, in order to allow enhancement in the transmitting efficiency of a transmission system using link aggregation, if the bandwidth usage rates of the physical links constituting the LAG are imbalanced, identification information of a factor packet that serves as a factor for the imbalance is estimated on the basis of a distribution rule and the second information about a data amount. In addition, the factor packet is distributed to physical links to which the factor packet is distributed, and a packet that is not the factor packet is distributed according to the distribution rule, which is based on, for each of the physical links constituting the LAG, a remaining bandwidth obtained by subtracting the usage bandwidth of the factor packet distributed to said physical link from the maximum available bandwidth of said physical link.

A data traffic analyzer is configured for detecting bursty data traffic on a data path. The data traffic analyzer measures data traffic parameters of the data path and analyzes the data traffic parameters of the data path to detect a bursty traffic pattern based on comparing the data traffic parameters to a time interval threshold T.sub.Limit which defines gaps between bursty data traffic. The measured traffic parameters include: i) a data traffic volume and/or a protocol data unit (PDU) count transmitted on the data path; and ii) a time stamp T.sub.LPU characterizing the last path usage (LPU) of the data path.

Various examples and schemes pertaining to on-demand network configuration of vehicle-to-everything (V2X) user equipment (UE) autonomy in New Radio (NR) mobile communications are described. An apparatus implemented in a first user equipment (UE) receives a signaling from a network node of a wireless network. Based on the signaling, the apparatus operates simultaneously in a network-controlled mode and an autonomous mode such that: (a) the first UE operates in the network-controlled mode with respect to resource allocation on a first sidelink with a second UE, and (b) the first UE operates in the autonomous mode with respect to resource allocation on a second sidelink with the second UE or a third UE.
