摘要： Various communication systems may benefit from the appropriate control of the timing of communication. For example, certain wireless communication systems may benefit from packet data convergence protocol windows, for example in the case of split bearers being in use. A method can include transmitting a plurality of protocol data units over a bearer mapped to a plurality of logical channels. The protocol data units can be transmitted in a radio link control unacknowledged mode. The method can also include managing at least one transmission characteristic of the transmitted plurality of protocol data units.

摘要： In accordance with example embodiments as described herein there is at least an apparatus and method to perform determining that at least one packet data convergence protocol data unit of a packet data convergence protocol sublayer are duplicate packet data convergence protocol data units of the packet data convergence protocol sublayer having been submitted for transmission on two or more carriers in a communication network; signaling to a control sublayer an indication of each packet data convergence protocol data unit that is a duplicate packet data convergence protocol data unit; and based on the indication, preventing a trigger of a radio link failure when a number of retransmissions based on the duplicate packet data convergence protocol data units reaches a threshold number of retransmissions. Further, there is at least an apparatus and method to perform transmitting packet data convergence protocol data unit duplicates over two or more carriers; receiving an indication that indicates packet data convergence protocol data unit has been correctly transmitted via one of two or more carriers; and upon receiving the indication, instructing to discard other packet data convergence protocol duplicates over carriers other than the one of two or more carriers with a successful delivery.
