摘要:
An object of the present invention is to provide a mechanism for improving the performance of a radio access network. The object is achieved by a data packet (200) in a first network node (110). The first network node (110) is adapted to transmit the data packet (200) to a second network node (120), over a radio link (130). The first network node (110) and second network node (120) are comprised in a wireless communications network (100). The data packet (200) comprising a data packet header (210) and a data packet payload (220). The data packet header (210) comprising at least one length indicator (211, 212, 213, 214, 215). The data packet payload (220) comprising a number of consecutive packet data units (221, 222, 223), of the same specific size. The number of consecutive data units (221, 222, 223), of the same size is indicated in the data packet header (210) using a first length indicator of the at least one length indicators (211, 212, 213, 214, 215).

The present invention relates to a UE, base station network node and methods thereof in a cellular mobile communication system. One method concerns handover from a first radio base station to a second radio base station wherein, it comprises the steps receiving a notification from the first radio base station that currently serves said UE, said notification indicating the last packet to be transmitted to this user equipment from said first radio base station on a first connection; and informing the second radio base station by a request to commence transmission from this second radio base station when the notified last packet is received at the UE.

The present invention relates to a base station and a method in a mobile telecommunication network for allocating and de-allocating uplink base station processing resources to a mobile terminal. The base station are adapted to communicate to a mobile terminal on an uplink channel supporting macro-diversity, and the base station is adapted to be a non-serving base-station without control of the resource allocation to the mobile-terminal. The base station comprises means for predicting a likelihood of successful decoding of a future transmission, and means for allocating or de-allocating processing resources based on said prediction.

The present invention relates to a method and to a transceiver (100) of a telecommunications system capable in exchanging protocol data units (PDUs) with another transceiver(s). Each PDU being identified using a sequence number. The transceiver, according to the present invention, is arranged to receive from the other transceiver a status report indicating positively acknowledged PDUs and negatively acknowledged PDUs. The transceiver (100) is further configured to compare sequence numbers in the report with previously acquired sequence numbers from previous reports and to prevent retransmissions of one or several PDUs based on the comparison.
摘要:
A method in a user equipment (UE) includes transmitting, to a first radio base station, one or more protocol data units (PDUs) that are each associated with a respective Internet Protocol (IP) packet. The method also includes receiving one or more feedback indications from the first radio base station, each indicating whether a corresponding PDU was successfully received, and transmitting a retransmission of at least one PDU based on the feedback indications. Additionally, the method includes determining a time point for performing a cell change based on whether the first radio base station has not successfully received all of the PDUs associated with IP packets for which a complete IP packet has been transmitted and performing the cell change at the determined time point.

A method for configuring a connection between first and second peer entities in a wireless telecommunications network comprises sending a hash value between the first and second peer entities, the hash value being a compact representation of information relating to a connection configuration procedure between the first and second peer entities.
摘要:
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.
摘要:
An object of the present invention is to provide a mechanism for improving coverage in a wireless communications system. The object is achieved by a method in a sending node (210) for transmitting a data unit to a receiving node (220). The data unit comprises a number of bits. The sending node (210) and the receiving node (220) are both comprised in a wireless communications system (200). According to the method, the sending node (210) obtains (606, 810) a value n associated with the data unit. Then, the sending node (210) selects (608, 814) a transmission time instance depending on n, such that a function exists that uniquely associates the selected transmission time instance with n. Finally, the sending node (210) transmits (612, 818) the data unit to the receiving node (220) in the selected transmission time instance, without the value n.
