摘要： Disclosed herein are apparatus, methods and computer program products for transmitting signals in different frequency sub-bands used in a particular cell of a cellular wireless communications system in accordance with a power sequence and for selecting modulation schemes to be used in transmitting the signals in the different frequency sub-bands in dependence on signal transmission power allocated to the sub-bands in the power sequence. In the power sequence, signals to be transmitted in at least one sub-band are allocated a higher signal transmission power level than signals to be transmitted in other sub-bands used in the particular cell of the cellular wireless communication system. The differing signal transmission power levels allocated to the different sub-bands typically results in different SINR for signals transmitted at the higher signal transmission power levels and signal transmitted at the lower signal transmission power levels. In order to reduce the SINR difference between signals transmitted in the different sub-bands, modulation schemes are selected in dependence on the signal transmission power levels allocated to signals transmitted in the sub-bands.

摘要： Frequency resources for common control regions of a control channel are defined or determined as a function of at least bandwidth and an identifier of a specific cell. Communications between a wireless network and a mobile device are then done using the defined/determined frequency resources of the common control regions of the control channel. In the non-limiting embodiments: the bandwidth is bandwidth of a cell or of a component carrier; the frequency resources are defined/determined further as a function of an offset value; the common control regions are of an ePDCCH and the offset value differs from a channel edge offset value for common control regions of all other ePDCCHs of all other adjacent cells or all other transmit nodes in the same cell; and the frequency resources comprise frequency stripes (which may be interleaved by resource element groups) distributed in frequency across the bandwidth.

摘要： An approach for providing interference measurements for device-to-device communication is disclosed. A logic generates a control signal to instruct a plurality of stations to perform measurement relating to interference or path loss by the stations. The logic then receives measurement information from the stations and determines, based on the measurement information, whether resources are to be scheduled to provide direct communication between two of the stations.

摘要： A first parameter such as an indicator of modulation and coding scheme MCS for a first shared channel SCH codeword and a second parameter for a second SCH codeword are determined. From a locally stored mapping rule a bit sequence that explicitly indicates the first parameter and that implicitly indicates the second parameter is chosen, and a first control channel CCH codeword is transmitted with the explicit bit sequence that explicitly indicates the first parameter for the first SCH codeword and a second CCH codeword is sent companion to the first CCH codeword, wherein the second parameter for the second SCH codeword is implicitly indicated by the explicit bit sequence of the first CCH codeword. The receiving party determines the second parameter by its own locally stored mapping rule, and an indicator in each CCH codeword may be used to inform the receiver that the two (or more) CCH codewords are associated with one another and to use its mapping rule to determine the second parameter.
