Abstract: To configure uplink sounding signal transmission in a wireless communication network, sets of configuration parameters for uplink sounding signal transmissions are determined for a given mobile terminal. Each of the sets of configuration parameters comprises a priority, a frequency-domain parameter and a time-domain parameter. The sets of configuration parameters are transmitted to the mobile terminal, thereby configuring the mobile terminal to generate different sounding signals and use the priorities to select from among the different sets of configuration parameters in the event of a sounding signal transmission collision.

Abstract: To configure uplink sounding transmissions by mobile terminals in a wireless communication network, sets of configuration parameters for uplink sounding signal transmissions are determined for a given mobile terminal. Each of the sets of configuration parameters comprising frequency-domain and/or time-domain parameters. The sets of configuration parameters are transmitted to the mobile terminal, thereby enabling the mobile terminal to generate different sounding signals used by the wireless communication network to estimate different properties associated with at least one of uplink signals and uplink channels.

Abstract: A method of scheduling wireless data transmissions between a mobile terminal (701) and a base station using multiple component carrier signals is disclosed. The method comprises the steps of: receiving in the mobile terminal information from the base station indicating available component carriers; detecting in the mobile terminal at least one dynamic parameter indicative of the mobile terminal's current ability to handle component carriers having non-contiguous bandwidths; determining in the mobile terminal in dependence of the at least one dynamic parameter which of the available component carriers to utilize; and transmitting from the mobile terminal to the base station information indicating the component carriers determined to utilize.

Abstract: Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal is configured to effectively ignore “UP” transmit power control commands in the event that the mobile terminal is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal, a plurality of transmit power control commands are received. An accumulated power control value is adjusted in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal is not in a power-limited state. Transmit power settings for each transmission are calculated based on the accumulated power control value and the one or more radio link parameters.

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 an 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.

Abstract: A base station determines multiple different sets of configuration parameters for uplink sounding signal transmissions for a mobile terminal. Each of the multiple different sets of configuration parameters comprises frequency-domain and time-domain parameters. Each of the time-domain parameters indicates a time offset (in number of subframes) of a sounding signal, and a period (in number of subframes) of the sounding signal. The base station transmits information representing the multiple different sets of configuration parameters to the mobile terminal. The mobile terminal receives the information from the base station and generates different sounding signals based on the multiple different sets of configuration parameters.
