摘要： A user equipment method and a user equipment in idle mode, for enabling the compilation of information concerning the radio coverage within a cell of a base station. The user equipment is configured to communicate with the base station. The method comprises the actions of detecting a loss of coverage and transmitting coverage information, to be received by the base station. A network node receives the coverage information from the idle mode user equipment. The received coverage information is identified as information related to the occurrence of lost coverage for the user equipment. Thereafter is the received coverage information logged and usable for adjusting the transmission power of the base station and/or for network planning purposes.

摘要： In a mobile station for use in a cellular radio system, the mobile station is adapted to increase radio measurements relating to the currently best cell at times when the user is preparing to set up a call in order to increase the likelihood that a mobile station is camping in the correct cell when setting up a call. This is obtained by adding a third mode to the already existing idle and active modes. The additional mode provides for an increased amount of idle mode measurements compared to the conventional idle mode.

摘要： Systems and methods for identifying Passive Intermodulation (PIM) products are disclosed. Some embodiments use RAN Performance Measurement (PM) counters, of actual DL Traffic Load to correlate with UL noise and interference counters. By using counters, the DL traffic is correlated to the increase in noise and interference in order to determine which DL carrier combinations are causing degradation to which UL carriers. In this way, aggressor-victim grouping can be identified through normal downlink traffic load with uplink interference to identify passive intermodulation products. This can be done for all aggressor-victim groups within a radio base station site or cluster of sites. Also, some embodiments enable estimating the maximum PIM interference created by the aggressor carriers. This helps operators to quantify the impact of PIM and can enable them to take counter measures. These embodiments are Radio Access Technology (RAT) agnostic and operator agnostic for the aggressors within a site.

摘要： The invention discloses a method (700) for finding differences in path loss between a plurality of RF paths between a first (120, 130) and a second (120, 130) transceiver in a wireless communications system (100). During defined 5 intervals of time (SACCH1-SACCH4), only one RF path is used to transmit from one of said transceivers to the other of said transceivers, and the receiving transceiver measures the strength of the signal received during at least a number of said intervals, thus making it possible to compare signal strength and thereby path loss between different RF paths, which in turn 10 makes it possible to find imperfections in one or more of said RF paths.
