    摘要： A base station (BS) and method for controlling handover in a wireless communication system. The BS serves a first cell in a first cell layer overlapping with a second cell layer, and the first cell has a different distribution of configured amounts of uplink and downlink resources than a second cell in the second cell layer. The BS monitors amounts of uplink and downlink resources utilized by a user equipment (UE) in the first cell and adjusts at least one parameter controlling handover of the UE to the second cell based on the resources utilized by the UE, and on information regarding configured amounts of uplink and downlink resources in the first and second cells. This increases the likelihood that the UE will be served by one of the first and second cells in which the configured amounts of resources better matches the amounts of resources utilized by the UE.

    摘要： A method in a first base station having a first coverage area at least partly overlapping with a second coverage area of a second base station, the first base station operating within a first transmission power range and the second base station operating within a second transmission power range. The method includes determining radio link quality of a user equipment (UE1) connected to the first base station and being located in an adjustable extended coverage range of the second base station; requesting from the second base station, interference related measurements for unused physical channels or for physical channels at least partially overlapping with physical channels used by UE1 and having the radio link quality falling below a threshold value; and deciding for UE1, based on the interference related measurements, whether a handover to the second base station should be performed.

    摘要： A method for cell selection comprises obtaining of user equipment specific information for a user equipment that is present in a first cell of a first base station. The user equipment specific information comprises information of a prevailing radio situation and information of a present decoding performance. A present capability of the user equipment for handling increased interference and a measure of a cell selection offset required to cover the user equipment by a second cell is estimated from the user equipment specific information. It is decided on modifying a cell selection offset for handover between the first cell and the second cell, in dependence on the estimated present capability of the user equipment for handling increased interference and the cell selection offset required to cover the user equipment by the second cell.

    摘要： A method in a first network node (110) for coordinating data transmissions between wireless devices (121, 122) and two or more antennas associated with at least one second network node (210, 310) in a wireless communication network (100) is provided. The wireless devices (121, 122) are served by the at least one second network node (210, 310) and the at least one second network node (210, 310) is configured to perform coordinated data transmission or reception. First, the first network node (110) identifies two or more groups of wireless devices based on mutual spatial correlation between the wireless devices (121, 122). Then, the first network node (110) selects a subset of wireless devices from two or more of the identified groups of wireless devices based on a criterion that relates to a data rate of each of the wireless devices. The first network node (110) then schedules wireless devices from the selected subset of wireless devices for the coordinated data transmission or reception of the at least second and third network node (210, 310). The first network node (110) then coordinates the data transmission or reception between the two or more antennas comprised in the at least one second network node (210, 310) and the scheduled wireless devices.A first network node and a computer program are also provided.

    摘要： A method in a user equipment for obtaining a Modulation and Coding Scheme, MCS is provided. The MCS is to be used for a transmission between the user equipment and any one or more out of the network node or a second network node. The user equipment has knowledge about a modulation and coding index table. The user equipment receives (201) one or more offset values from the network node. The user equipment obtains (205) an MCS indicator related to said transmission. The user equipment then obtains (206) the MCS from the modulation and coding index table based on the MCS indicator and the one or more offset values.
