    摘要： A method in a network node in control of a cell in a cellular telecommunication network for reducing intra-cell interference between user equipments (UE) residing in said cell and performing random access (RA). The method comprises the steps of arranging groups of preamble sequences where the sequences within each group are orthogonal to each other, assigning one such group to the cell, from which group the UEs performing RA randomly selects a preamble, and assigning one or more additional group(s) of preamble sequences to said cell if the RACH or traffic load exceeds a certain threshold. The invention further relates to a radio network node in a cellular telecommunication system, capable of carrying out said method.

    摘要： A technique for detecting one or more access bursts (112) in a random access channel (110) is described. Each access burst includes a transmission preamble, the transmission preamble being a member of a preamble set including sequences of preamble symbols that can be obtained by cyclically shifting a basic preamble sequence. A detector (118, 120) in a radio base station (108) determines correlation information indicative of a correlation of a single correlation preamble with each of the one or more received transmission preambles, wherein the correlation preamble is a member of the preamble set. The one or more access bursts are detected based on the correlation information.

    摘要： A cellular communications system that utilizes OFDM in its radio interface is capable of utilizing either a first subcarrier spacing or a second subcarrier spacing. Which of these is presently in use is indicated by generating a first type of synchronization signal in response to the first subcarrier spacing presently being in use, and generating a second type of synchronization signal in response to the second subcarrier spacing presently being in use. Whichever of the first type of synchronization signal and the second type of synchronization signal was generated is transmitted. To distinguish between the first and second types of synchronization signals, a time domain representation of the second type of synchronization signal includes a plurality of instances of the first type of synchronization signal.
