摘要： Pilot signal sequences with a low Peak-to-average ratio are generated by a method comprising the steps of providing a first signal sequence consisting of a first number, m, of signal elements and known to have a frequency spectrum with either identical or nearly identical non-zero amplitude values in a first frequency interval, performing an invertible first transformation of the first signal sequence into a first frequency spectrum in the first frequency interval, the first frequency spectrum consisting of m first frequency samples, performing a second transformation of the first frequency spectrum into a second frequency spectrum consisting of n frequency samples in the first frequency interval, the n frequency samples being formed by the m first frequency samples and a third number, n minus m, of additional second frequency samples, which have zero amplitude, such that the second frequency spectrum has m frequency spikes distributed over the second frequency interval, and performing a third transformation, which forms an inverse of the first transformation, to the second frequency spectrum to obtain a second signal sequence forming the pilot signal sequence.]

摘要： A communication method and a communication arrangement in a Code Division Multiple Access radio system is provided According to one embodiment, at least two transceivers of the radio system communicate with a packet switched connection through a radio interface. The quality of the packet switched connection is measured and a target Signal Interference Ratio is adjusted based on the quality measurement. When a transceiver receiving packets transmits a request to retransmit in the case of failure in reception of at least one packet, a transceiver transmitting packets is configured to retransmit each packet requested as a response to the request. The target Signal Interference Ratio for retransmission of a packet is set lower than the target Signal Interference Ratio for the first transmission of the corresponding packet.

摘要： According to an embodiment a user equipment UE transmits uplink control signals using one or more chunks of uplink frequency spectrum that contain a simultaneous uplink shared channel; and for the case where there is no simultaneous uplink shared channel available, the UE transmits uplink control signals using only a single chunk of uplink frequency spectrum. In various embodiments the control signals are ACK/NACK control signals transmitted on an uplink control channel, the uplink shared channel comprises a chunk-specific uplink control channel, and each chunk comprises a component carrier of a LTE-A system. Downlink assignment index bits may be included in a downlink grant to the UE which indicates how many chunks in total are allocated in a current downlink subframe. The UE can also use ACK/NACK control signal bundling over chunks in addition to either or both of chunk- specific ACK/NACK control signals or ACK/NAK control signal multiplexing.
