摘要： A method for a terminal of a cellular telecommunication system for determining system information about a node of a network of the telecommunication system is disclosed. The telecommunication system enables determination of the system information by the terminal from information transmitted from at least one cell operated by the node, where the telecommunication system employs Orthogonal Frequency Division Multiple Access. The method comprises receiving a transmission signal, comprising reference symbols and synchronisation symbols, from a network node of the at least one cell; estimating, for each transmit antenna of the network node, a preliminary channel estimate based on the received reference symbols; and estimating a pre-coding vector, being associated with transmission by at least one transmit antenna of the network node of the at least one cell, for the synchronisation symbols. Corresponding features for computer program, decoder and terminal are also disclosed.

摘要： A method for investigating a signal in an OFDMA transmission is disclosed. The method comprises receiving the OFDMA transmission and obtaining a resource grid comprising resource elements of the transmission; determining a set of pairs of the resource elements, wherein the resource elements of the pair are disjoint; for each pair, comparing signals of the resource elements of the pair; determining a statistical test value based on the comparisons; and processing the statistical test value to obtain a desired output about the signal. A computer program for implementing the method, a receiver arrangement adapted to perform such investigation, and a communication apparatus using such receiver arrangement are also disclosed.
