    Abstract: The invention relates to a method for performing a data transmission between a sending entity and a receiving entity. The sending entity provides the data in form of data packets being ordered in a sequence. In order to make the data transmission more efficient when packet reordering occur on the communication link between the protocol entities, the receiver entity at a reception of a data packet which is out of the sequence order, delays a triggering of a reordering procedure for providing the sequence order at the receiver by means of a delay parameter whereby during the duration of the delay the establishment of the sequence order of the incoming data packets is controlled by means of a controlling parameter.

    Abstract translation: 本发明涉及一种用于在发送实体和接收实体之间执行数据传输的方法。 发送实体以按照顺序排列的数据包的形式提供数据。 为了使数据传输在协议实体之间的通信链路上发生分组重排序时更有效,接收端实体在接收到不符合序列顺序的数据分组时延迟触发重新排序过程以提供 通过延迟参数在接收机处的序列顺序,由此在延迟的持续时间期间,通过控制参数来控制输入数据分组的序列顺序的建立。

    Abstract: UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n=the number of bits in C/T field.
