Abstract: This application provides a sequence-based signal processing method and apparatus. 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} including N elements, and fn is an element in the sequence {fn}. The determined sequence {fn} is a sequence that meets a preset condition. Then the N elements in the sequence {fn} are respectively mapped to N subcarriers to generate and send a first signal. With the determined sequence, when the signal is sent by using the PUCCH, a low cross-correlation between sequences can be maintained, and a relatively small peak to average power ratio (PAPR) value and a relatively small and cubic metric (CM) value can be maintained. Therefore, a requirement in a communications application environment in which the signal is sent by using the PUCCH is met.

Abstract: This application provides a sequence-based signal processing method, a signal processing apparatus, a computer readable storage medium, and a computer program product. A sequence meeting a requirement in an environment in which a signal is sent by using a reference signal or a control channel is determined, where the sequence is a sequence {fn} including N elements, fn is an element in the sequence {fn}, and the determined sequence {fn} meets a preset condition; then the N elements in the sequence {fn} are mapped to N subcarriers respectively, to generate a first signal; and the first signal is sent. By using the foregoing determined sequence, weak cross-correlation between sequences can be maintained, and a relatively small PAPR value and a relatively small CM value of the reference signal or the control channel can be maintained, to meet a requirement in a communications application environment in which the signal is sent by using the reference signal or the control channel, particularly when a data signal on which π/2-BPSK modulation is performed is sent or frequency shaping is performed on the reference signal or the control channel.

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: The present invention relates to the field of mobile communications technologies, and in particular, to a method for sending and receiving information. The user equipment in embodiments of the present invention may determine a frame structure of a serving cell, where in addition to an uplink subframe and a downlink subframe, the frame structure in the embodiments of the present invention further includes a first subframe, and the first subframe includes a first symbol used for downlink transmission, a first GP, and a second symbol used for uplink transmission. More symbols used for downlink transmission and more symbols used for uplink transmission than those in a frame structure in the prior art are introduced by introducing the first subframe, thereby improving downlink transmission and effectively reducing a value of k, that is, reducing a service delay in feeding back a HARQ-ACK.
