Title:
METHOD FOR TRANSMITTING UPLINK SIGNAL
Document Type and Number:
Japanese Patent JP2023041067
Kind Code:
A
Abstract:
To provide a method for transmitting ACK/NACK signals and control information by efficiently arranging them in a resource area while taking priorities between the ACK/NACK signals and the control information other than the ACK/NACK signals into consideration in the transmission of uplink signals.SOLUTION: A method for transmitting uplink signals including ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals, is disclosed. The method serially multiplexes the control signals and the data signals, sequentially maps the multiplexed signals in this way within a specific resource region composed of a plurality of symbols and a plurality of virtual subcarriers by a time axis priority mapping method, and after that, arranges the ACK/NACK signals to both symbols adjacent to a symbol to which a reference signal is transmitted among the plurality of symbols. Thus, the uplink signals can be transmitted by improving receiving reliability of signals having a high priority.SELECTED DRAWING: Figure 6
