    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} 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: This application discloses a signal transmission method, including: mapping a first sequence into a first subcarrier group, and mapping a second sequence into a second subcarrier group. The subcarriers included in the first subcarrier group and the second subcarrier group are subcarriers on a same time domain symbol. The subcarriers in each of the first subcarrier group and the second subcarrier group are evenly distributed subcarriers. The first sequence is a Fourier transform sequence of a third sequence. The second sequence is a Fourier transform sequence of a fourth sequence. The elements at a same location in the third sequence and the fourth sequence are not both non-zero elements.

    Abstract: The present disclosure describes a message transmission method. In one example method, a first signal is received by a first device from a second device using a radio channel. A second signal, corresponding to and different from the received first signal, is transmitted by the second device to the first device. Information carried by the second signal corresponds to one of M state values. A first sequence corresponding to one or more subcarriers occupied by the second signal is directly proportional to a product of a preset second sequence and a third sequence in a state sequence set. Channel information of the radio channel is estimated by the first device according to the received first signal and the preset second sequence. The information carried by the second signal is determined by the first device according to the estimated channel information of the radio channel and the received first signal.

    Abstract: A method and apparatus for allocating and processing sequences in a communication system is disclosed. The method includes: dividing sequences in a sequence group into multiple sub-groups, each sub-group corresponding to its own mode of occupying time frequency resources; selecting sequences from a candidate sequence collection corresponding to each sub-group to form the sequences in the sub-group by: the sequences in a sub-group i in a sequence group k being composed of n sequences in the candidate sequence collection, the n sequences making a |ri/Ni−ck/Np1| or |(ri/Ni−ck/Np1) modu mk,i| function value the smallest, second smallest, till the nth smallest respectively; allocating the sequence group to cells, users or channels. It prevents the sequences highly correlated with the sequences of a specific length from appearing in other sequence groups, thus reducing interference, avoiding the trouble of storing the lists of massive sequence groups.

    Abstract: Method and apparatus are provided for mapping and detecting a control channel. For the same aggregation level, according to a signaling length of a control channel corresponding to a component carrier, a corresponding search space is determined for at least two control channels that have the same signaling length, so as to enable the at least two control channels that have the same signaling length to use the same search space. The at least two control channels having the same signaling length are mapped to the determined corresponding search space. Therefore, conflicts between the control channels are reduced, and the number of times of blind detection of the control channels is also reduced.

    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: This application relates to a sequence detection method and a device. In embodiments of this application, K candidate frequency domain root sequences may be first filtered based on a differentiation result of received first sequence and differentiation results of candidate frequency domain root sequences, and a candidate frequency domain root sequence to which the first sequence actually corresponds only needs to be determined based on the first sequence and the K candidate frequency domain root sequences. For example, there are U candidate frequency domain root sequences. In this case, a current calculation amount is calculation of U*Cs cross correlation values. In embodiments of this application, a calculation amount is calculation of only L*U+K*Cs, where Cs represents a quantity of sampled time domain cyclic shift values, and L represents a quantity of differentiation granularities.
