摘要： A method in a terminal for providing an ACK/NAK message to a base station is provided. The terminal counts the number of assigned downlink subframes detected from the base station resulting in k. The terminal then establishes whether each of a number of transport blocks comprised in the counted k downlink subframes is correctly received or not. In the case when each one of the transport blocks, comprised in the k downlink subframes is estimated as correctly received the terminal provides to the base station an encoded ACK message for the k subframes, which comprises k, the number of subframes.

摘要： Method and arrangement in a terminal for receiving data packets from a base station and providing feedback to the base station. The feedback concerns the reception status of the received data packets and may comprise an ACK/NAK. The method comprises receiving and decoding data packets from the base station in a subframe. It is further established whether any data packet within the received subframe is not correctly received and detected whether any subframe, expected to be received, has been missed. Further, acknowledgement information ACK/NAK is generated, a scrambling code selected with which the ACK/NAK is scrambled. The scrambled ACK/NAK is then sent to the base station, concerning the reception status of the data packets within the received subframes.

摘要： The invention is a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation. The signaling mechanism allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers. Semi-statically reserved resources for the transmission of control information on the uplink component carrier may be dynamically shared byuser terminals that are assigned multiple downlink component carriers for downlink transmissions. Implicit or explicit resource indication can be used in combination with dynamic resource indication.

摘要： A method and an arrangement (800) in a radio network node (120) for adapting transmission power of resource elements for demodulation reference signals, referred to as "reference elements" are provided. The radio network node (120) is configured for multiple-input multiple-output transmission, referred to as "MIMO transmission", to a user equipment (110). The MIMO transmission comprises at least three layers. Two consecutive subcarriers of a resource block carry at least three reference elements. A first subcarrier of the resource block carries data elements. The radio network node (120) adapts transmission power of said at least three reference elements such that an average transmission power, over said two consecutive subcarriers, of said at least three reference elements is equal to a transmission power, for the first subcarrier, of the data elements for said at least three layers. The radio network node (120) uses the adapted transmission power to transmit, to the user equipment (110), said at least three reference elements.

摘要： A method in a base station, for adapting Sounding Reference Signals (SRS) power control setting in a user equipment is provided. An SRS specific fractional pathloss compensation factor "α sounding " value is decided based on a specific purpose for using SRS received from the user equipment. The α sounding value is decided independent of a value of a data specific fractional pathloss compensation factor "α data " to be used for data transmission to the base station. The user equipment is informed to use the decided α sounding value for adapting the SRS power control setting in the user equipment. This enables the user equipment to send SRS, using power according to the adapted power control setting.

摘要： The present invention relates to methods and arrangements in a wireless communication system that enable the use of multi-codeword transmission and ACK/NACK compression with low performance loss. It also enables the use of advanced receivers of reasonable complexity. This is achieved by a solution based on the even distribution of the symbols of separately coded blocks of information bits over the available physical resources before transmission. Each physical resource will thus carry a mixture of symbols from all blocks of information bits, which results in a more similar channel quality for the blocks of information bits. A compressed ACK/NACK message corresponding to the blocks of information bits will thus be more accurate and the performance loss due to the ACK/NACK compression can be reduced.

摘要： A method of selecting at least one communication link in a wireless communication network is proposed, comprising the steps of transmitting from at least one transmitting node in the network a pilot signal from each of at least two transmitter antennas of the transmitting node, receiving the pilot signals from the at least two transmitter antennas in a receiving terminal, estimating, in the terminal, a covariance matrix of the channel, based on the pilot signals received, determining the pathloss for each antenna based on the covariance matrix, selecting one of at least two possible links for the communication between the terminal and the transmitting nodes. The terminal is enabled to measure on each transmitter antenna individually, which provides a better tool for link selection and cell selection.
