Abstract: A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined. The sequence is a sequence {fn} consisting of 12 elements, fn represents an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition. Then, the 12 elements in the sequence {fn} are respectively mapped to 12 subcarriers, to generate a first signal, and the first signal is sent. By using the determined sequence, when the signal is sent by using the PUCCH, a low correlation between sequences can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and a relatively small cubic metric (CM) value can be maintained. Therefore, a requirement of a communication application environment in which the signal is sent by using the PUCCH is met.

Abstract: Embodiments of the present disclosure provide, among other implementations, sequence determining methods. One example method provides a sequence group, and one sequence group number is corresponding to at least two sequences, where one sequence is used for mapping to consecutive subcarriers, and at least one other sequence is used for mapping to equally-spaced subcarriers. In some embodiments of the present disclosure, as high as possible cross-correlation between a sending signal obtained after equally-spaced mapping is performed on a sequence in a sequence group can be determined, and a sending signal obtained after continuous mapping is performed on another sequence in the group.

Abstract: A data sending method, a related device, and a system are described. The method includes sending, by a network device, resource location information of a first reference signal and a physical channel to a terminal, where a first time-frequency resource on which the first reference signal is mapped overlaps a second time-frequency resource corresponding to the physical channel. An overlapping resource is not used to transmit the physical channel, and a third time-frequency resource in the second time-frequency resource other than the overlapping resource is used to transmit the physical channel. Alternatively, an overlapping resource is used to send a second reference signal; or an overlapping region is used to send a second reference signal, where the terminal skips sending the first reference signal, and the second reference signal is orthogonal to the first reference signal.

Abstract: A sequence distributing and sequence processing method and apparatus in a communication system are provided. The sequence distributing method includes the following steps: generating sequence groups including a number of sequences, the sequences in the sequence groups are determined according to the sequence time frequency resource occupation manner which is supported by the system; distributing the sequence groups to cells. The method avoids the phenomenon that signaling transmission is needed to distribute the sequences to the cells for different time frequency resource occupation manner, and saves in so far as possible the wireless network transmission resource occupied during the process of distributing the sequences through distributing the sequence groups comprising a number of sequences to the cells.
