Abstract: The present invention relates to a method and a network node for selecting transmission mode to a cell providing Multicasting/Broadcasting Multimedia Service, MBMS, which cell is served by the network node in a MBMS single frequency network and comprising at least one user equipment receiving or requesting MBMS data. The network node obtains (601) a first parameter related to a quality of the MBMS experienced by the at least one user equipment and compares Based the first parameter with a predefined first threshold value. Based on the result of comparison the network node selects (604) a transmission mode to the cell.

Abstract: A radio base station and a method therein are provided for determining where in a cell a UE, being served by the radio base station, is located. The method includes receiving at least a first and subsequently a second Reference Signal Received Power (RSRP) value from the UE, and comparing the received first and second RSRP values. The method further includes selecting a first threshold value based on the comparison indicating increasing RSRP values corresponding to the UE moving towards a cell-center area, or selecting a second threshold value based on the comparison indicating decreasing RSRP values corresponding to the UE moving towards a cell-edge area. Further, the method includes determining whether the UE is located in the cell-center area or the cell-edge area using the selected threshold value.

Abstract: A base station in a LTE system and a method for use in the base station (400) are provided for allocating power in downlink transmissions for a UE. A report is received, from the UE, comprising a Reference Signal Received Quality, RSRQ, indicating a current channel quality of a downlink transmission with multiple subcarriers. A fairness factor used for achieving fairness in scheduling between UEs served by the base station is retrieved, from a resource management scheduler of the base station; and a combined factor is determined based on the received RSRQ and the retrieved fairness factor, for resource blocks, RBs, related to the downlink transmissions, the RBs comprising subcarriers pertaining to resources to be allocated to the UE. Then, a power is determined for the resource RBs based on the determined combined factor; and the determined power for the downlink transmission for the UE is allocated.

Abstract: The embodiments disclose a method for adaptive resource allocation by an AP in a radio communication network utilizing MIMO-BF. The method comprises: calculating the PMI correlations between a first UE being served by the AP and each of a plurality of candidate UEs to be allocated resources by using the latest PMIs reported by the respective UEs, wherein the PMI correlation is indicated by the phase difference between the first UE and a candidate UE, and the plurality of candidate UEs are within the coverage of the AP; prioritizing the plurality of candidate UEs to be allocated resources in accordance with the calculated PMI correlations; selecting one or more second UEs from the plurality of candidate UEs based on the priority of the plurality of candidate UEs; and allocating resources to the one or more second UEs so as to serve them subsequently.
