摘要： Methods and apparatus are disclosed for scheduling sub-carriers in an Orthogonal Frequency Division Multiplexing (OFDM) communication system. In an exemplary method, channel quality metric values for each of a plurality of sub-channels are determined, in view of a selected mobile terminal. For each of two or more threshold levels for the channel quality metric, sub-carrier groups composed of sub-carriers corresponding to sub-channels having channel quality metric values superior to the threshold level are identified, and an estimated data throughput is calculated for each of the identified sub-carrier groups. One or more of the identified sub-carrier groups is allocated to the selected mobile terminal according to the estimated data throughputs.

摘要： The present invention relates to methods and arrangements in a multi-antenna radio communication system, in particular to methods and arrangements for improved multiple HARQ transmission in such systems. While HARQ transmission schemes, as known in the art, only can consider the fact whether or not a transmission attempt has been successful the present invention provides a HARQ retransmission scheme that considers the reception quality for already performed transmissions of a same data packet when selecting a resource allocation for necessary re-transmissions. Resource allocation for retransmissions is based on a pre-defined metric indicating a quality of the reception of the previous transmission attempts. Such a metric can be derived from a quality measure derived in the receiver unit, e.g. a CQI or CSI-based value, or an appropriate measure of the mutual information, e.g. the accumulated conditional mutual information (ACMI).

摘要： A mechanism for increasing a sectorization order in a first sector of an antenna array. The object is achieved by a method in a network node. The network node and antenna array are comprised in a wireless communication system. The antenna array is deployed with a first sectorization. The network node comprises a first number of signal connections. Each signal connection is adapted to transmit and receive signals. The method comprises the step of splitting the first number of connections into a number of groups. Each one of the respective connection groups corresponds to one respective virtual sector resulting in a number of virtual sectors. The method further comprises the step of mapping the number of virtual sectors to the first sector, such that the first sector is split into the number of virtual sectors.

摘要： A method of adapting resource allocation parameters to reach one or more quality targets with improved accuracy is proposed. New information measurements based on the so-called mutual information, preferably at block-level, are introduced. The MI-based information measurements of a previous transmission, the channel prediction of a subsequent transmission and one or more quality requirements, are used to determine the amount and type of resources, e.g. time, frequency and power resources, that are to be used for the subsequent transmission. The resource allocation can for example comprise power allocation and/or link adaptation and the invention enables an advantageous implementation with cooperative link-adaptation and power allocation. The proposed method is useful in connection with ARQ/HARQ retransmissions.
