摘要： Measurement handling is of interest in a user equipment, UE, in connected mode, with the UE being configured with multiple downlink component carriers, CCs. The UE evaluates (S1) the signal quality of one specific CC of the configured CCs against a configurable threshold to determine the need for neighbor cell measurements. The UE performs (S2) neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold. In this way, robust and efficient measurement handling is provided, even though the UE is configured with multiple component carriers.

摘要： A user equipment connection supervision method in a user equipment, of a network node initiated random access procedure to force a declaration of connection failure is provided. The user equipment is connected to a wireless communication network via a wireless connection to the network node. After receiving (401) one or more commands from the network node, to perform random access procedure, the user equipment performs one or more attempts to initiate random access procedure by sending (402) one or more access request messages to the network node as a response to the received command. When no response to the sent access request message is received from the network node within a predetermined threshold value, the user equipment declares (406) failure of the wireless connection.

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： 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 user equipment unit (30) and a base station node (28) which is configured for operation with a synchronous HARQ protocol and with capability of sending data on an E-DCH channel either (1) in a nominal mode in single transmission time intervals of a predetermined length, or (2) in an extended mode in a pseudo transmission time interval. The pseudo transmission time interval comprises a first transmission time interval in which the data is transmitted and a second transmission time interval in which the data is re-transmitted. The second transmission time interval is consecutive to the first transmission time interval, and the first transmission time interval and the second transmission time interval are each of the (same) predetermined length.

摘要： The present invention relates to a method and an arrangement for reducing a state transition time from a power saving state for a user equipment (18) in a communication network. The state transition time is reduced by retaining in the user equipment (18) one or more information parameter, such as the radio network temporary identifier for a high speed downlink shared channel (H-RNTI), when performing a state transition to said power saving state so as to enable a time reduction when said user equipment switches back from said power saving state.

摘要： A method and nodes for providing adaptive segmentation in a higher protocol layer interacting with a lower protocol layer. An adaptable segmentation limit (200, 204), defining a threshold of a largest Protocol Data Unit (PDU) that is to be submitted to a lower protocol layer, is deployed at a higher protocol layer interacting with the lower protocol layer. For each Service Data Unit (SDU; 201, 203) arriving at the higher protocol layer, it is determined if the respective SDU can fit into the segmentation limit or not. Each SDU that do not fit into the segmentation limit is segmented into PDUs (205, 206) which are smaller than or equal to the segmentation limit, while no segmentation is performed on SDUs that fit into the segmentation limit.

摘要： The present invention relates to a node and a method thereof for a mobile telecommunication network connectable to a controlling node and wirelessly connectable to mobile terminals. The node is adapted to have an uplink connection to a mobile terminal, wherein the mobile terminal is adapted to have a second uplink connection to at least a second node such that data transmitted from the mobile terminal may be received at the node and at the at least the second node. The node comprises means for estimating whether data transmitted from the mobile terminal received at the at least the second node is received stronger than the data received at said node and means for discarding data received from the mobile terminal if it is estimated that the data is received stronger at the at least the second node than the data received at said node.

摘要： Select diversity in cellular radio communications involving both the radio access network and the mobile radio ensures that an optimal base station cell under a current condition is selected for communicating with the mobile radio. A candidate set of radio base station cells is defined for a radio connection between the radio network and the mobile radio. Packets are sent via the radio network to each of multiple radio base stations having a cell in the candidate set. The mobile radio detects a current quality of communication for the radio connection, and based on that detected quality, the candidate cell set may change. The mobile radio selects one of the cells in the candidate cell set to send a next or specific data packet based on one or more selection criteria.

摘要： The present invention relates to methods and arrangements to enhance transmission quality in a Push-to-Talk system comprising a sending mobile unit MB1, and a receiving mobile unit MB2 used by a receiving subscriber B. The receiving unit MB2 comprises a Play-Out-Buffer POB and a Repeat Buffer RB, whereby a stream of sequences 15-19,25-29,35-39 is sent from the sending unit MB1 to the receiving unit MB2. The method comprises the following steps:—The incoming stream of sequences 15-19,25-29,35-39 is collected into the Repeat Buffer RB and into the Play-Out-Buffer POB. The Play-Out-Buffer has a storage size and a point for commencing play-out that provides low voice delay, and the Repeat Buffer has a storage size that provides high sound quality. —The incoming stream is played-out from the Play-Out-Buffer POB to the receiving subscriber B. —Replay is commenced of a defined part 36-39 of the sequences 15-19,25-29,35-39 collected in the Repeat Buffer RB.
