摘要： A method performed in a wireless network includes receiving signals within a downlink frequency domain to enable channel estimation and measuring two or more signals only for two or more frequency bands of the downlink frequency domain that correspond to two or more uplink frequency bands associated with a scheduling grant or channel allocation that correspond to physical uplink channel frequency bands. The method also includes calculating path loss values for each of the frequency bands and calculating a total power based on the path loss values corresponding to the frequency bands. The method further includes determining a power allocation per frequency band based on the calculated total power to be applied to an uplink transmission and allocating the total power.

摘要： Methods and apparatus for generating, transmitting, and processing error control information in a wireless communication system are disclosed. The error control information is designed so that the probability of a NACK-to-ACK error in transmission is lower than the probability for an ACK-to-NACK error. Multiple ACK/NACK bits are transmitted along with one or more side information bits that indicate the relative quantities of ACK values and NACK values among the ACK/NACK bits. In an exemplary method for generating error control information in a communication device, a plurality of ACK/NACK bits indicating whether corresponding transport blocks were successfully received are generated. One or more side information bits are formed as a function of the ACK/NACK bits, the side information bits indicating the relative quantities of ACK values and NACK values among the ACK/NACK bits, and transmitted along with the ACK/NACK bits to the remote communication node.

摘要： Method and arrangements for scheduling transmission resources in a first node in a cell comprised within a wireless communication network. The first node is arranged to communicate over a communication channel with at least one user equipment within the cell. The communication is made by using a frame comprising uplink resources and downlink resources with a switching point between the downlink resources and the uplink resources. The method comprises the step of obtaining a parameter referring to the expected transmission quality of the communication and/or the expected coherence properties of the communication channel. The method also comprises scheduling a transmission on an uplink or downlink resource. The resource is located on a time distance from the switching point. The time distance is based on the obtained parameter.

摘要： A terminal is configured to receive data packets from a base station and provide feedback to the base station. The feedback concerns the reception status of the received data packets and may comprise an ACK/NAK. A method in the terminal 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, and a scrambling code is 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： 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 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.
摘要翻译：本发明涉及无线通信系统中的方法和装置，其能够使用多码字传输和具有低性能损失的ACK / NACK压缩。它还可以使用合理复杂的高级接收机。这是通过基于在传输之前的可用物理资源上的分开编码的信息比特块的符号的均匀分布的解决方案来实现的。因此，每个物理资源将携带来自所有信息比特块的符号的混合，这导致信息比特块的更相似的信道质量。因此，与信息比特块相对应的压缩ACK / NACK消息将更加准确，并且可以减少由于ACK / NACK压缩引起的性能损失。
