    Abstract: The present disclosure generally relates to managing a radio access node cluster (4) comprising a plurality of radio access nodes (2). By determining connectivity metrics and comparing to predefined thresholds, a decision is taken if a radio access node (2) of the radio access node cluster (4) is to be detached from radio access node cluster (4) or if a neighboring radio access node (6) is to be added to the radio access node cluster (4). All radio access nodes belonging to the radio access node cluster (4) share a common cell identifier.

    Abstract: A first radio network node (110) and a method therein for measuring interference as well as a second radio network node (120) and a method therein for enabling the first radio network node to measure interference are disclosed. The first radio network node (110) obtains (201) configuration information for indicating a designated subframe in which a reference signal for measurement of the interference is to be transmitted by the second radio network node (120). The second radio network node (120) obtains (202) configuration information for configuring a designed subframe for transmission of a reference signal. The first radio network node (110) receives (205), in the designated subframe indicated by the configuration information, the reference signal transmitted by the second radio network node (120). The first radio network node (110) determines (206) a value of the interference based on the reference signal.

    Abstract: The present disclosure relates to a method and device (10) for enabling downlink (DL) coordinated multipoint (CoMP) communication. In particular it relates to a method of enabling CoMP in legacy user equipments, i.e. devices that only measures and reports the channel quality of the link to its primary serving point. The method comprises the steps receiving the at least one DL channel quality measurement (SI), receiving at least one uplink (UL) measurement of the respective UL channels from the wireless device to one of the multiple access points (S2), and estimating a coordinated DL multipoint channel quality of a coordinated multipoint channel corresponding to one or more different coordinated transmission states of the access points, based on the at least one DL channel quality measurement and the received UL measurements, by assuming that the DL path gains from the multiple access points to the wireless device are proportional to the UL path gains to the multiple access points for respective access point, thereby predicting link quality of inter-access-points-coordinated DL multipoint transmissions from the access points.

    Abstract: The present disclosure introduces allocation of resources to one or more UEs based on a determined allocation priority and/or allocation probability in, e.g., Time Division Duplex (TDD) based radio communication networks. The disclosed technology provides the ability for a subframe to be configured as a “flexible” subframe, which can be dynamically allocated as either a downlink subframe or an uplink subframe. For each “flexible” subframe, an allocation priority and/or allocation probability is determined and subsequent resource allocation to user equipments (UEs) can be based on the determined allocation priority and/or allocation probability. Hereby, it is made possible to reduce interference in, e.g., TDD based radio communication networks.
