    摘要: The invention relates to an OFDM-transmitter, comprising means for transforming (400) data to be transmitted in frequency-to-time transformation to a basic waveform containing waveform components representing subbands of the spectrum of the signal. The transmitter comprises means for forming (402) at least one alternative waveform from components of the basic waveform, where at least one component in the alternative waveform is delayed in time, and means for selecting (414) a waveform for transmission from the group of waveforms, containing the basic waveform and the at least one alternative waveform. The invention also relates to a method for transmitting an OFDM signal, a method for processing an OFDM signal and an OFDM signal processing arrangement.

    摘要: The present invention relates to a method and network element for classification of bit strings such as data packets on a per-flow basis, wherein a plurality of classification fields are searched for in respective search trees based on a matching procedure in which an index value is obtained in a leaf node of a search tree for each classification field. Index values obtained in said searching step are used to derive a policy to be applied to said data packet, wherein the number of index values is reduced by combining intermediate results of the searching step or the deriving step. Thereby, computational efficiency can be improved and memory requirements reduced.

    摘要: The invention relates to a method for supporting a handover of a mobile station (1) from a first radio access unit (3, 8) of a wireless communication network (2) to a second radio access unit (4, 9) of a wireless communication network (2). In order to improve a context transfer in the case of a handover of the mobile station (1), the mobile station (1) transmits information about its activity state to the second radio access unit (4, 9) when it is to be handed over to the second radio access unit (4, 9). The invention relates equally to such a mobile station, to such a second radio access unit, to a wireless communication system comprising such a mobile station and such a second radio access unit, and to a software code causing the transfer of information at the mobile station.

    摘要: Piggy-backed requests for resources are handled in a packet-switched communications system. A terminal arrangement sends an access request to a network element in order to request permission to use communications resources for transmitting a data packet found in a transmission buffer of the terminal arrangement. Knowledge is established about a predicted data packet which is to appear in the transmission buffer of the terminal arrangement in the near future. The terminal arrangement transmits to the network element an access request for predicted traffic, requesting permission to use communications resources for transmitting said predicted data packet once it appears. Said access request for predicted traffic is piggy-backed onto another transmission.

    摘要: This invention relates to a method for setting up transfer-related resources, comprising assigning (401) an identifier (12a, 212a) to at least one data unit (12, 212), wherein said identifier associates said at least one data unit with a first entity (10, 210, 510) in a first network node (501), transferring (404) said at least one data unit from said first node to a second node (502), and setting up a second entity (11, 211, 511) in said second network node after at least one of said at least one data units has been transferred from said first network node to said second network node, wherein said second entity is associated with said at least one data unit via said identifier and wherein said first and second entity jointly implement a function related to the transfer of said at least one data unit. The invention further relates to a computer program, a computer program product, a system and a device.
