The present disclosure relates to method and apparatus for reporting processing delay related information in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving a configuration on measurements and reporting of reordering statistics; measuring a reordering delay (RD); calculating the reordering statistics; and sending a radio resource control (RRC) message including the reordering statistics based on a pre-defined condition.

An embodiment is a data sequence correction method. The data sequence correction method including temporarily saving data with sequence information imparted thereto in a ring buffer, the ring buffer having a predetermined number of storage regions corresponding to the sequence information, and being provided with a monitoring section made up of one, or two or more consecutive sequence numbers, and an acceptance section in which a start or a second sequence number of the monitoring section is a start sequence number, and the sequence number ahead by a count of storage regions of the ring buffer including the start of the monitoring section is an end sequence number.

Methods and apparatuses are provided for generating a protocol data unit (PDU). An apparatus may comprise a processor configured to provide a medium access control (MAC) entity and a segmentation entity. The MAC entity may indicate an amount of data associated with the segmentation entity to be multiplexed by the MAC entity. The segmentation entity may segment, based on the indicated amount of data, a service data unit (SDU) into a segment, and the MAC entity may multiplex the segment into a MAC protocol data unit (PDU). The MAC PDU may include a field that indicates whether the segment is included and whether the segment is a last segment. The apparatus may further comprise a transmitter configured to transmit the MAC PDU.

A processor is configured to receive, from a first device, a plurality of first-direction packets belonging to a flow of communication, pass the first-direction packets to a second device, receive, from the second device, a plurality of second-direction packets belonging to the flow, pass the second-direction packets to the first device, calculate, after receiving each of at least some of the second-direction packets, an estimated in-flight number, by assuming that the second-direction packet acknowledges receipt of a number of the first-direction packets that is based on an estimated average number of received first-direction packets acknowledged by the second-direction packets, the estimated in-flight number being an estimated volume of payload data, contained at least partly in the first-direction packets, that has been passed by the processor to the second device but has not yet been received by the second device, and to regulate the flow, based on the estimated in-flight number.
