20110014907 | METHODS AND ARRANGMENTS IN A WIRELESS COMMUNICATIONS SYSTEM - The present invention relates to methods and arrangements for uplink retransmissions from a user equipment to a radio base station in a UTRAN with enhanced uplink. The UE transmits a subframe comprising physical control channel(s) and physical data channel(s) in an initial transmission. According to the present invention, one or more of the physical control channels are transmitted with a lower transmission power level in all or some of the retransmitted subframes in the uplink. This results in reduced control overhead (a smaller part of the transmission power resource is used for control signaling) and thus reduced interference from the overhead. At the same time, the transmission power resource no longer used for the physical control channel information, can be used to increase the transmission power level of the physical data channel information in these retransmitted subframes, which improves the uplink coverage. | 01-20-2011 |

20120033755 | Transmit Mode Switching for MIMO Base Stations - In a transmitter using at least two transmitting antennas a STTD transmitter is used in combination with a common pre-coding transmitter for power amplifying power balancing. A selector can be provided for selecting data/channels transmitted using STTD and common pre-coding such that for one channel type, STTD or common pre-coding is used whereas the combination of both STTD and common pre-coding is used for a different data/channel type. By selectively using both STTD and common pre-coding for power amplifier power balancing, an improved power balancing is achieved. At the same time, the STTD gain is obtained in the relevant cases but the STTD loss in other cases is avoided. | 02-09-2012 |

20130183994 | Reducing Interference in a Radio Access Network - 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. | 07-18-2013 |
20130225225 | DEVICE AND METHOD FOR TRANSMIT POWER CONTROL - A controlling node for a cellular communications system, arranged to determine and transmit commands for Transmit Power Control, TPC, to one or more Mobile Terminals, MTs, in at least one cell in the system. The controlling node is arranged to classify an MT as being in one of a number of states, and to use differing methods for determining an MT's TPC command depending on which state the MT is in, so that one method is used for determining TPC commands to an MT in the active state and another method is used for determining TPC commands to an MT in the passive state. | 08-29-2013 |
20130231159 | HANDLING CONTROL CHANNELS IN A WCDMA SYSTEM - A radio base station for use in a Wideband Code Division Multiple Access network. The radio base station comprises a receiver for receiving radio signals transmitted over the air by users, and a first processor for processing the received signals in order to recover signals for a first group of users, the “cancellers”, and a first set of control signals for a second group of users, the “cancellees”. The radio base station further comprises an interference canceller for performing interference cancellation on the received signals using the recovered signals in order to generate an interference cancelled signal, a second processor for subsequently processing the interference cancelled signal in order to recover a second set of control signals for the cancellees, and a controller for using the control signals to control the transmission of data towards said cancellees. | 09-05-2013 |
