    摘要： In a heterogeneous network, low power cells are detected by correlating a first and second signal originating from an unknown cell, such as synchronization signals, e.g., SSS received in a first and second time period (e.g., subframes 0 and 5 of a frame with corresponding sets of possible SSS signals. The cell identities for the candidate cells can be used to determine corresponding reference symbol sequences for the candidate cells. The final determination of the cell identity is then made by correlating a third signal originating from the unknown cell, such as a reference signal received in a third time period (e.g., an almost blank subframe or a broadcast subframe) with the set of reference signals for the candidate cells. The correct cell identity is determined to be the cell identity yielding the greatest correlation with its corresponding reference signal.

    摘要： Example embodiments presented herein are directed towards a first radio node (400), and corresponding methods therein, for determining a bandwidth of a second radio node (402). The first and second radio nodes are configured for use in a communications network. The bandwidth is determined based on a correlation between a signal received form the second radio node and at least one known signal which are transmittable on one or more known radio resources. Such bandwidth determination eliminates the need for the wireless terminal to receive such information via system information broadcasted from a cell.

    摘要： The present disclosure relates to a method of radio communication between a first radio device and a second radio device using a first frequency resource and a first communication protocol by means of a network node, at least one of the radio devices being served by said network node. The method comprises determining a second frequency resource to use for non-network assisted device-to-device (D2D) communication between the first and second radio devices in case of a radio link failure between said at least one radio device and the network node. The method also comprises determining a second communication protocol to use for the non-network assisted D2D communication between the first and second radio devices in the case of a radio link failure between said at least one radio device and the network node.
