The preset condition is xn=y(n+M)mod K, where

M∈{0, 1, 2, . . . , 5}, a length of the first sequence is K=6, n=0, 1, . . . , K−1, A is a non-zero complex number, and j=√{square root over (−1)}. The first signal is a signal modulated by using π/2 binary phase shift keying (BPSK). The first frequency-domain resource comprises K subcarriers each having a subcarrier number of k, k=u+L*n+delta, L is an integer greater than or equal to 2, delta∈{0, 1, . . . , L−1}, u is an integer, and subcarrier numbers of the K subcarriers are numbered in ascending or descending order of frequencies.-

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.

Abstract: An uplink transmission method and a communication apparatus. A terminal device receives first indication information indicating at least two uplink carriers to effectively reduce control signaling overheads. The terminal device sends uplink transmission on the at least two uplink carriers based on the first indication information. The uplink transmission is sent on the at least two uplink carriers in response to control signaling overheads being reduced. The use of the at least two uplink carriers increases an uplink capacity.

Abstract: Embodiments of this application disclose example data processing methods and example apparatuses. One example method includes determining, by a first terminal device based on a parameter group, a first sequence including N elements, where the parameter group includes a first parameter, a second parameter, and a cyclic shift value, the first sequence is obtained by performing cyclic shift on a second sequence based on the cyclic shift value, and the second sequence is determined based on the first parameter and the second parameter. The first terminal device can then send a signal to a network device based on the first sequence.

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: 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, where the sequence is a sequence {fn} consisting of N elements, fn is an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition; then, the N elements in the sequence {fn} are respectively mapped to N subcarriers to generate a first signal; and the first signal is sent. By using the determined sequence, when a signal is sent by using a PUCCH, a low sequence correlation can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and cubic metric (CM) value can also be maintained, thereby meeting a requirement of a communication application environment in which a signal is sent by using a PUCCH.

Abstract: This application relates to the field of wireless communications technologies, and in particular, to a data processing method, apparatus, and system. This application provides a data processing method. A transmit device uses a sequence to carry data and a reference signal. The transmit device carries the two channels of data on an odd element and an even element of the sequence, respectively. The transmit device successively maps the sequence that carries the two channels of data to allocated subcarriers, and then sends the data in an orthogonal frequency division multiplexing (OFDM) manner. This application is intended to decrease cubic metric (CM)/peak-to-average ratio of a transmitted signal of an orthogonal frequency division multiplexing OFDM system through sequence design and mapping of the two channels of data to subcarriers, thereby improving link quality of an entire transmission system.

Abstract: A slot type indication method and an apparatus and a slot type determining method and an apparatus are provided. Under the slot type indication method, a first indication information can be generated by a network device. The first indication information indicates a slot type of a first slot. When the slot type of the first slot is a predefined type, the first indication information further indicates whether a second slot is an uplink-only slot, and the first slot is a slot that includes a downlink control channel. The first indication information can be sent, by the network device, by using the downlink control channel of the first slot.
