Abstract: A node (100, 200) of a cellular network obtains reports of measurements for a given cell (20) of the cellular network. The measurements are performed by one or more communication devices (10) associated with a surrounding cell (21) of the given cell. Each measurement indicates a received signal strength of a signal (RS) from the given cell (20). On the basis of the received signal strengths, the node (100) determines a level of interference generated by the given cell (20) with respect to the surrounding cell (21).

Abstract: A network node and a method performed by the network node for congestion control in a Radio Base Station, RBS, are provided. The method comprises determining that the RBS is congested. The method further comprises determining an interference level in a neighboring RBS caused by wireless devices currently being served by the RBS, or determining a level of inter-cell coupling between the RBS and the neighboring RBS. Still further, method comprises increasing a value of an average received signal level target, P0, for wireless devices currently being served by the RBS if the RBS is congested, if the determined interference level in the neighboring RBS is below an interference threshold or if the level of inter-cell coupling is below a coupling threshold.

Abstract: Known HO performance indicators comprise Retainability Rate and HO Successful Rate. The Retainability Rate is defined as the ratio between abnormal connection releases and the total number of releases, and HO Successful Rate is defined as the ratio of successful HOs and the total number of HO attempts. The application proposes two new HO performance indicators LowCqiRateWhenHo (522) and LowUISinrRateWhenHo (524). These two HO performance indicators are based on radio link conditions before a HO for the DL and UL channels respectively. The indicator LowCqiRateWhenHo is defined as the ratio of low, i.e. below a threshold (514). CQI measurement samples of users (502) just before a HO and is as a measure of DL connection quality during HO. The indicator LowUISinrRateWhen Ho is defined as the ratio of low, i.e. below a threshold (516). SINR measurement samples (506) in UL just before a HO and is as a measure of UL connection quality during HO.

Abstract: A method and a network node (110) for obtaining a nominal power “P0” of transmissions on an uplink channel and a pathloss compensation factor “?” are disclosed. The cell (101) is associated to a non-regular scenario, at least partly defined by respective locations of further cells of the cellular network (100). The further cells are neighbors to the cell (101), which is located at a location within the cellular network (100). The network node (110) generates, for each further cell, a respective regular scenario in relation to the cell (101). The generation is at least based the respective location corresponding to said each further cell and the location of the cell (101). The network node (110) determines, also for each further cell, a respective P0 and a respective ? for each respective regular scenario.

Abstract: An offset is monitored which is applied by at least one access node (100) of a cellular network to adapt a signal quality value determined for a radio connection to a communication device (10). The adapted signal quality value is applied in a first control loop to select, a modulation and coding scheme for the radio connection. The offset is adapted in a second control loop, starting from an initial value and depending on feedback information concerning transmissions on the radio connection. Depending on the monitored offset, the initial value of the offset to be applied by the at least one access node (100) with respect to further radio connections to communication devices is determined.
