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 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: The present disclosure provides an information transmission method, including: generating first information; determining a first sequence from N candidate sequences based on the first information; and sending the first sequence. The first information belongs to N candidate information. A mapping between the first information and the first sequence belongs to P mappings. Each of the P mappings includes a mapping between the N candidate information and the N candidate sequences. The N candidate sequences are generated based on N dedicated cyclic shift values and a first initial cyclic shift value. In at least two mappings, dedicated cyclic shift values used to generate candidate sequences corresponding to a same candidate information are different, where the same candidate information belongs to L candidate information in the N candidate information, both P and L are integers greater than 1, and the L is less than or equal to N.

Abstract: This application discloses methods an apparatuses for sending and receiving uplink control information in the field of communications technology. In some implementations, a terminal device may receive first downlink control information (DCI) from a network device; determine, based on the received first DCI, that an uplink shared channel scheduled by using the first DCI is used to send only uplink control information (UCI); and send first UCI to the network device through the uplink shared channel scheduled by using the first DCI. In other words, the network device indicates to the terminal device by using DCI so that the terminal device can determine, based on an indication of the network device, whether the uplink shared channel scheduled by using the DCI is used to send only the UCI.
