摘要： Method and arrangement in a Radio Base Station RBS in a wireless communication system, for handling load coupling in softer handover. The method in an RBS involves receiving (702) signals from a plurality of UEs connected to the RBS, using a category 1 receiver. Further, the load experienced by the respective UEs is determined (704). The effect of load coupling in softer handover of at least one of the UEs connected to the RBS is estimated (706), and, when the estimated effect of load coupling of a UE fulfills a predefined criterion (708:1), at least one entity in the RBS is modified (710), such that the effect of load coupling is reduced or avoided.

摘要： A method and apparatus for reducing an effect of user interference on other users in an uplink of a radio access network using interference suppression. A user, for example, the user experiencing the highest interference, is selected from a plurality of users using the radio access cell. A perceived Rise over Thermal value for the user after interference suppression is predicted in the event that scheduling grants to an interfering user in the radio access network are altered. On the basis of the prediction, scheduling grants to the interfering user are altered, thereby reducing the interference for the selected user.

摘要： A radio base station and a method therein for scheduling an uplink radio resource to a first user equipment in a wireless communication system which employs CDMA are provided. The method includes measuring an Interference Suppression (IS) gain for each user equipment in a set of user equipments currently being served by the radio base station. The method further includes determining a user constellation pertaining to information regarding the different user equipments in the set of user equipments and their respective bitrates, and updating a table of IS gains with the measured IS gain in bins corresponding to the determined user constellation. The method further includes predicting a load based on at least the updated table, and scheduling the uplink radio resource to the first user equipment at least partly based on the predicted load.

摘要： A method for reporting positioning data from a node B in a cellular communication system comprises performing (210), in a node B, of a measurement of a time of radio signal propagation concerning signalling with a first user equipment within a coverage of the node B. The measurement gives a time value. The time value is coded (212), in the node B, as a multi-symbol time report sequence. Auxiliary positioning information data concerning the first user equipment is obtained (214) in the node B. At least one symbol of the multi-symbol time report sequence is modified (216) (218) in the node B, for representing the auxiliary positioning information data. The modified multi-symbol time report sequence is reported from the node B. A positioning method, a node B and a positioning node are also disclosed.

摘要： Embodiments herein relate to a method in a radio network node (12) for enabling management of radio resources in a radio communications network, which radio network node (12) serves a first cell (11). The radio network node measures a received total power value at the radio network node (12) in the first cell (11). The radio network node (12) computes a factor indicating a load in the first cell (11). The radio network node (12) estimates a noise floor level in the first cell (11). The radio network node (12) computes a utilization probability value of the load in the first cell (11) and a neighbor cell interference value simultaneously in a non-linear interference model. This is based on the measured received total power value, the computed factor, and the estimated noise floor level in the first cell (11), which neighbor cell interference value is an interference from at least one second cell (14) affecting said first cell (11), and where at least one of the utilization probability value of the load in the first cell (11) and the neighbor cell interference value is to be used for managing radio resources in the radio communications network.

摘要： A method for noise rise estimation in a wireless communication system comprises measuring of received total wideband power a plurality of times and computing an estimate of a noise floor measure based on a number of the measured received total wideband powers. An interference whitening is performed based on one of GRAKE, GRAKE−and chip equalizer. A useful signal power for the first user after interference whitening is determined. A first user noise floor compensation factor is derived based on combining weights for the first user used in the interference whitening. A code power to interference ratio measure for said first user is obtained. A noise rise measure is calculated, based at least on the useful signal power for the first user after interference whitening, the first user noise floor compensation factor, the code power to interference ratio measure for the first user and the noise floor measure.

摘要： The present invention relates to a method and arrangement in a wireless communication system, e.g. an evolved UMTS Terrestrial Radio Access Network, for improved scheduling and admission control of the uplink by providing an improved determining of power-related quantities, e.g. neighbor cell interference levels, for specific tones and providing more accurate recursive estimation of noise-related quantities, e.g. noise floor power estimates, for specific tones. The method and arrangement obtains a neighbor cell interference measure for each subset of tones from at least a noise floor measure for each subset of tones based on combined power quantities from the total uplink power per subset of tones and dividing said noise floor measure into sub noise floor measures for each subset of tones, said dividing dependent on the bandwidth of each subset of tones.
