摘要： A radio base station suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver and a status report requester. The transceiver is configured to facilitate wireless transmission between the radio base station and a wireless terminal over an air interface, including transmission of a radio link bearer for the connection over a downlink from the radio base station to the wireless terminal. The status report requester is configured to determine, according to one or more pre-defined criteria, whether to request from the wireless terminal a status report for a radio bearer prior to the radio base station transferring user data for the connection to another radio base station in conjunction with a handover.

摘要： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

摘要： A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer of the client device.

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.

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： According to the invention data in a number of logical downlink intended for one or more mobile terminals are received in a first mapping unit, where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel and processes said data.
