摘要： A cellular radio communication system includes a first serving cell and a second non-serving cell. A mobile radio is currently served by a first base station in the first cell. An uplink radio transmission from the mobile radio will cause or causes inter-cell interference in the second non-serving cell. Accordingly, an estimate is made of the inter-cell interference in the second non-serving cell associated with the mobile radio's uplink transmission. If the estimated inter-cell interference in the second non-serving cell exceeds a predetermined threshold, then control is performed so that the inter-cell interference in the second non- serving cell is limited, e.g., by managing radio resources so that the estimated inter-cell interference in the second non-serving cell is or becomes less than the predetermined threshold.

摘要： The invention relates to a method and device (14) of controlling bit rate of a terminal (11, 12, 13) included in a group of terminals. To this end, a method is provided comprising the steps of acquiring a predetermined QoS parameter for the terminal, which parameter stipulates target QoS to be given to the terminal relative to other terminals in the group, and acquiring either one or both of (a) at least one measure of a channel condition of the terminal and (b) at least one capacity measure of the terminal. Further, the method comprises the step of controlling the bit rate of the terminal on the basis of a reference weighting factor created by a combination of the acquired predetermined QoS parameter, the acquired at least one measure of a channel condition of the terminal and/or the acquired at least one capacity measure of the terminal.

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： Control of uplink transmit power for a first mobile station operating with scheduled uplink data transmissions. A change in uplink scheduled status for the first mobile station is detected (301). Filtering of uplink interference measurements for the first mobile station is adapted (302) to account for the detected change in uplink scheduled status for the first mobile station. Alternatively a change in uplink scheduled status for a second mobile station is detected and a current filtering state for filtering of uplink interference measurements for the first mobile station is adjusted by applying an estimated expected change in interference associated with the detected change. A signal quality for uplink transmissions from the first mobile station is determined (303) based on measurements of received signal strength from the mobile station and the filtered uplink interference measurements. An uplink transmit power command is generated (304) for the first mobile station based on a comparison of the estimated signal quality to a signal quality target.

摘要： A method, a mobile station and a computer program for controlling uplink transmit power of a mobile station capable of operating with scheduled uplink data transmissions. Uplink transmit power level for the mobile station is updated (304) based on received (303) uplink power control commands. Upon detecting a change (301) in uplink scheduled status for the mobile station, the process of updating (304) the uplink transmit power level is adjusted to account for the detected change in uplink scheduled status.

摘要： This disclosure relates to a Radio Network Controller, RNC, (102, 200) a base station (106, 300), and to methods therein. By extracting (204, 304) information from one or more flows of Protocol Data Units, PDUs, which information is accessible on a certain protocol layer only, congestion control is enabled and performed on another protocol layer based on said information. The present disclosure avoids that inappropriate PDUs are discarded, which else would inappropriately affect the user performance.
