Abstract: There is described a method of controlling a basestation in a cellular wireless communications network, the method comprising, within the basestation, autonomously and dynamically adapting a maximum value for a total transmit power of the basestation, such that interference between the basestation and other access points in the vicinity is minimized.

Abstract: A basestation receives a table containing information about a plurality of other basestations of the cellular communications network. The basestation and the plurality of other basestations are connected to a local area network. The operation of receiving the table includes receiving the table over the local area network from one of the other basestations. The table contains information for use by the basestation in automatically configuring itself. In the event that the basestation changes its configuration, the basestation updates said table with changed information and rebroadcasts the updated table to the other basestations.

Abstract: A basestation forms part of a group of basestations within a cellular communications network, and selects an identifying code for use in identifying transmissions from the basestation. The basestation receives from a management node a first list of identifying codes and a second list of identifying codes, wherein the identifying codes of the first list can appear in neighbor cell lists of basestations outside said group, and wherein the identifying codes of the second list can not appear in neighbor cell lists of basestations outside said group. The basestation determines whether there is at least one identifying code either in the first list of identifying codes or the second list of identifying codes that is not used by any other basestation in said group.

Abstract: A neighbor cell list is formed, for use in a basestation of a cellular communications network. For each of a plurality of neighbor cells, a value of a first component is assigned, depending on whether or not the basestation can detect signals transmitted from said neighbor cell. A value of a second component is assigned, depending on a history of successful or unsuccessful handover attempts to said neighbor cell. The values of the first and second components are combined to form a weighting parameter, for use in determining a handover priority to be given to said neighbor cell in the neighbor cell list.

Abstract: In a femtocell basestation of a cellular communications network, there is a potential difficulty that the basestation may be unable to select a scrambling code for its transmissions, without the risk of interference with other basestations using the same scrambling code. The femtocell basestation receives from a management system a list comprising at least one allowed scrambling code for femtocell basestations, and also detects, in information broadcast by at least one macrocell basestation, at least one allowed scrambling code available in an area containing the basestation. If it is determined that use of each scrambling code that is allowed and is available in an area containing the basestation would cause interference with another femtocell basestation, a parameter is set to ensure that a user equipment would perform a location update when moving between the coverage areas of said basestation and the other femtocell basestation. The parameter may be a MIB and/or SIB value tag.

Abstract: A basestation for a cellular communications network is intended to provide coverage over a small area, which may be within an area that already has cellular coverage from one or more existing basestations. The basestation is therefore able to detect signals transmitted from the other basestations, in order to make measurements of the radio environment. In particular, the basestation may be able to receive signals periodically on the system downlink frequencies.

Abstract: A downlink power is set for transmissions from a basestation of a cellular communications network, the cellular communications network comprising a group of such basestations. A target value for a signal strength with which the transmissions should be received, and a target value for a pathloss, based on measured values for pathlosses between basestations of the group, are both set. The downlink power is calculated, based on the target value for the signal strength, and on the target value for the pathloss.

Abstract: A basestation, for use in a cellular communications network, has a mechanism for reporting its transmit power. When the transmit power of the basestation is outside a reportable range, it reports an adjusted transmit power within the reportable range, and also transmits an adjustment factor, by which the adjusted transmit power differs from the transmit power. The basestation is also configured to adapt its power settings based on a reported transmit power of at least one other basestation, and is further configured to detect the reported transmit power of the at least one other basestation and to detect an adjustment factor transmitted separately by the at least one other basestation, and to adapt its power settings based on a sum of the reported transmit power and the adjustment factor.
