    摘要： The present invention is directed to methods for adjusting a guard period in a cellular wireless communication system, to a base station adapted to adjust a guard period, and to a network management entity for adjusting a guard period. One method comprises the steps: obtaining (S1) an indication of at least one downlink frame for an interference measurement; transmitting (S2) during the at least one indicated downlink frame an interference signal; measuring (S3) interference at least during a part of the guard period succeeding the indicated downlink frame; and setting (S4) at least one of an end time of at least one subsequence.

    摘要： In cooperative signal communication between a mobile terminal (200) and a plurality of access nodes (100-1, 100-2, 100-3), cooperation signals (20), e.g. received signals or signals to be transmitted, are communicated with the access nodes (100-1, 100-2, 100-3). The cooperation signals (20) are quantized according to a quantization parameter, e.g. quantization depth and/or quantization type, which is adapted on the basis of a cooperative communication parameter. The cooperative communication parameter is a characteristic of the cooperative communication process, e.g. modulation scheme.

    摘要： According to an embodiment of the invention, a method of operating a control node for communication with at least one receiving node is provided. The communication is structured in frames comprising several subframes (1) which may be divided into subbands in the frequency domain. The method comprises transmitting a control channel in a search area (8) of one of the subframes (1). The search area (8) comprises a configurable time span and may span one or more of the subbands.

    摘要： Some embodiments provide a method for transmitting a downlink control channel in at least one block of resources. The downlink control channel comprises a set of resource element groups. The method may be executed by a transmitting node, e.g., an eNB. The transmitting node first determines whether to transmit the downlink control channel using localized or distributed transmission. Responsive to determining to use localized transmission, the transmitting node performs the transmission such that all resource element groups in the set that are comprised in the same block of resources are mapped to the same antenna port, and the antenna port depends on which subset of resource element groups in the block of resources are used for the downlink control channel.
