Abstract: THE PRESENT INVENTION RELATES TO METHODS AND ARRANGEMENTS IN A BASE STATION AND A USER EQUIPMENT FOR DETERMINING AN UPLINK TRANSMISSION TIMING CORRECTION FOR COMMUNICATION IN A TELECOMMUNICATION SYSTEM IN WHICH AGGREGATION OF COMPONENT CARRIERS IS APPLIED. THE BASE STATION RECEIVES A SIGNAL FROM THE USER EQUIPMENT ON A UPLINK (UL) COMPONENT CARRIER AND MEASURES THE ARRIVAL TIME OF THE SIGNAL. A TIMING CORRECTION OF THE UL TRANSMISSION TIMING BASED ON THE ARRIVAL TIME OF THE SIGNAL IS DETERMINED. THEREUPON THE BASE STATION DETERMINES FOR WHICH OF THE UPLINK COMPONENT CARRIERS USED BY THE USER EQUIPMENT THE TIMING CORRECTION IS VALID. THE TIMING CORRECTION AND THE VALIDITY INFORMATION IS SENT TO THE USER EQUIPMENT. THE USER EQUIPMENT ADJUSTS THE UL TRANSMISSION TIMING FOR EACH UL COMPONENT CARRIER THE TIMING CORRECTION IS VALID FOR. (FIG 5)

Abstract: Some embodiments herein relate to method in a user equipment (10) for determining a transmit power to be used by the user equipment when transmitting in a radio communications network, which user equipment (10) is served by a radio network node (12,12') in the radio communications network. The user equipment (10) receives, from the radio network node (12,12'), an indication indicating a set of power control parameters out of multiple sets of power control parameters, which multiple sets of power control parameters are stored at the user equipment (10). The user equipment (10) determines a transmit power based on the indicated set of power control parameters.

Abstract: THE PRESENT INVENTION RELATES TO A MOBILE TERMINAL DEVICE (401), A BASE STATION (400) AND A METHOD THAT MAKE IT POSSIBLE TO USE A CHANNEL QUALITY INDICATOR, CQI, REPORTING FORMAT FOR CQI REPORTING FROM THE MOBILE TERMINAL DEVICE TO THE BASE STATION, WHICH CQI REPORTING FORMAT DEPENDS ON A SELECTED TRANSMIT ANTENNA CONFIGURATION. THE MOBILE TERMINAL DEVICE (400) IS ARRANGED TO RECEIVE A SIGNAL (404) FROM A NUMBER OF TRANSMIT ANTENNAS, WHICH SIGNAL INCLUDES A NUMBER OF SUBCARRIERS (412), AND TO DETERMINE THE CQI, REPORTING FORMAT FOR A COLLECTION OF THE SUBCARRIERS BASED ON THE SELECTED TRANSMIT ANTENNA CONFIGURATION. THE MOBILE TERMINAL DEVICE IS FURTHER ARRANGED TO DETERMINE A NUMBER OF CQI VALUES (409) RELATING TO SAID SUBCARRIERS IN ACCORDANCE WITH THE DETERMINED CQI REPORTING FORMAT AND TO TRANSMIT THE CQI VALUES TO THE BASE STATION IN A FEEDBACK SIGNAL (408). THE CQI REPORTING FORMAT IS ADAPTED TO THE SELECTED TRANSMIT ANTENNA CONFIGURATION SUCH THAT THE GRANULARITY OF CQI REPORTING DEPENDS ON THE SELECTED TRANSMIT ANTENNA CONFIGURATION.
