摘要： A method is described performed by a network node for supporting cell selection of user equipments, UEs, in a wireless communication network. The wireless communication network comprises low power nodes, LPN (230, 240), and high power nodes, HPN (210, 220). The LPNs and the HPNs are arranged to transmit signals wirelessly to UEs (251-254). The method comprises identifying (302) cell range expansion, CRE, areas of a group of LPNs, which CRE areas experience interference from a group of HPNs. The method further comprises counting (306) the number of HPNs in the group of HPNs and the number of LPNs in the group of LPNs, and when the numerical relation between the number of LPNs and the number of HPNs fulfills a predefined criterion, triggering (310) connection of a UE situated in any of the identified CRE areas to the LPN of the identified CRE area in which the UE is situated, and 221 when the numerical relation between the number of LPNs and the number of HPNs does not fulfill the predefined criterion, triggering (312) connection of a UE situated in any of the identified CRE areas to one of the HPNs of the group of HPNs.

摘要： A method is provided to determine radio channel metrics for radio communication between a plurality of remote radio heads and a wireless device. The method is performed in a remote radio head controller and comprising: selecting a first set of at least one remote radio head; selecting a second set of at least one remote radio head; configuring at least one switch such that only the remote radio heads of the first set communicate radio signals using a first radio branch; configuring at least one switch such that only the remote radio heads of the second set communicate radio signals using a second radio branch; determining a first radio channel metric for radio communication with the wireless device using the first radio branch; and determining a second radio channel metric for radio communication with the wireless device using the second radio branch.

摘要： A method is provided. The method includes determining a set of beam indexes including a first beam index and a second beam index; and determining a set of candidate matching networks. The method further includes performing an assigning step, where the assigning step includes: (a1) assigning a first matching network from the set of candidate matching networks to a first beam index; and (a2) assigning a second matching network from the set of candidate matching networks to a second beam index. The first matching network is different from the second matching network.

摘要： It is presented a method for controlling uplink contribution from a plurality of remote radio heads in a combiner. The method is performed in a remote radio head controller and comprises the steps of: determining a first set of at least one remote radio head; determining a second set of at least one remote radio head, wherein the first set and the second set are disjoint; selecting a first uplink carrier for a first wireless device; selecting a second uplink carrier for a second wireless device; and applying a configuration such that the at least one remote radio head of the first set refrains from contributing on a first channel with uplink signals on the second uplink carrier and that the at least one remote radio head of the second set refrains from contributing on the first channel with uplink signals on the first uplink carrier.

摘要： A method for inserting control data in a modulator comprising a plurality of frequency component inputs and a modulator output. The method is performed in the modulator and comprises receiving primary data subcarriers on respective frequency component inputs which are assigned for receiving primary data, receiving at least one control data subcarrier on a respective frequency component input which is not assigned to primary data, combining all frequency component inputs to one output signal, and providing the output signal on the output for transmission to a demodulator over a point-to-point medium.
