摘要： The embodiments herein relate to a method in a base station for adjusting transmission power in a communications network. The base station determines a first number m; P of historical transmit power control, TPC, commands based on a signal power and an interference level. The base station determines a second number 2k; n+Q of current TPC commands based on the first number m; P of historical TPC commands, or based on the first number m; P of historical TPC commands and a third number n−K of signal power and interference level pairs. The base station transmits a sequence of TPC commands comprising the first number of historical TPC commands and the second number of current TPC commands to the user equipment to adjust the user equipment's transmission power.

摘要： Methods and devices are provided whereby a cellular radio network, in particular a node in the network is configured to dynamically transmit data to UE from different cells while considering information that is not known to a central node, such as an RNC. This can in accordance with some embodiments be accomplished by decoupling the procedure of handling a set of cells form which simultaneous transmission of data to a UE can take place.

摘要： A minimum value or range for a transmit power gain factor is determined that controls the transmit power level over an enhanced uplink data channel relative so as to ensure delivery of a minimum data service requirement over the enhanced uplink data channel. The minimum value or range for the enhanced uplink data channel power gain factor may be determined based on a selected enhanced uplink transmission format and/or a maximum number of allowable transmission attempts over the enhanced uplink data channel for a communications session so that the required Quality of Service (QoS) for the communications session can be fulfilled and an expected uplink coverage gain can be reached. The minimum value or range for the enhanced uplink data channel power gain factor is also compatible with other techniques to increase enhanced uplink coverage such as autonomous retransmission and improved L2 techniques.
