Abstract: A radio communication system includes a plurality of mobile station apparatuses and a base statement apparatus. Each of the mobile station apparatuses selects the lowest number and the second lowest number of control channel elements (CCEs) in which downlink allocation information is detected, and obtains two combinations, to be applied to transmission antennas, of a physical resource block (PRB), a cyclic shift amount, and an orthogonal code sequence in the time domain, on the basis of values by adding the numbers of CCEs to an offset value broadcast by the base station apparatus. Each of the mobile station apparatuses spreads pilot signals using spread codes based on the two combinations, arranges the spread pilot signals in PRBs corresponding to the signals, and transmits the signals through the transmission antennas.

Abstract: 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.

Abstract: An allocation of downlink resources is received, which are monitored on I layers for data. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of those resources is selected an algorithm from among a first algorithm that bundles them in a first mode and a second algorithm that bundles them in a second mode. The selected algorithm is used on the generated resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate I reply bits which are then transmitted. At the network side a NACK reply bit is received, based on a pattern of the allocated downlink resources, a first algorithm that bundles them in a first mode or a second algorithm that bundles them in a second mode is selected. A bundling window and layer combination are determined from the selected algorithm, which gives the resource for retransmitting the NACK'd data.
