摘要： Method and arrangement in a base station for adjusting a channel quality indicator value of a wireless transmission between the base station and a user equipment. The base station, the user equipment and a relay node are comprised in a multi-hop wireless communication system and adapted to intercommunicate in a first transmission mode and a second transmission mode. The method comprises sending a radio signal to be received by the user equipment, obtaining a measurement of the channel quality indicator value, determining if the transmission mode of the sent radio signal is different from the transmission mode of the obtained channel quality indicator value measurement, and adding a channel quality indicator offset value to the channel quality indicator value, if the transmission mode of the relay node is determined to be the first transmission mode while the channel quality indicator was measured and obtained in the second transmission mode.

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 (SINR) 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 (910) for the channel quality metric, sub-carrier groups (940) 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 a method in a base station (14, 400) and a base station (14, 400) for predicting a frequency dependent Channel State Information, CSI for scheduling and link adaptation of resource blocks of an operating bandwidth, based on frequency band CSI information related to at least one UE, the method comprising the steps receiving a wideband CSI related to UE (step 302), receiving a UE-selected subband CSI for a bandwidth part (step 302), calculating the difference: the UE-selected subband CSI for the bandwidth part minus a non UE-selected SB CSI the wideband CSI (steps 314, 328, 338), and updating a non UE-selected SB CSI for at least the bandwidth part, based on the calculated difference (steps 318, 332, 342). A faster more reliable prediction method based on UE-selected SB CSI values, is hereby achieved.

摘要： Relay reporting in a wireless network is implemented by efficiently allocating radio resources based on the nature or criticality of the type of relay report. According to an embodiment, a method of communicating with a relay located in a wireless network includes instructing the relay when to transmit reports based on a mapping of different categories of relay reports to one or more different reporting schemes. Reports are received from the relay based on the relay report category and the corresponding reporting scheme. According to another embodiment, a method of reporting information from a relay to a network node of a wireless network includes generating different categories of reports at the relay for transmission to the network node. A reporting scheme associated with each report category is identified and each report is transmitted to the network node in accordance with the reporting scheme identified for the corresponding report category.
