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 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： The technology disclosed provides the ability for a subframe to be configured as a "flexible" subframe. As a result, at least three different types of sub frames in a TDD system may be configured: a downlink ("DL") subframe, an uplink ("UL") subframe, and a "flexible" subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

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.
