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 provides example reference signal (RS) transmission methods and example communication apparatuses. One example reference signal transmission method includes receiving, by a terminal device, first information in a first time unit, where the first information triggers the terminal device to transmit a RS. The terminal device can then transmit the RS in a second time unit, where the second time unit is indicated by a time offset indicator n in valid uplink transmission time units starting from the first time unit.

Abstract: A signal sending method, a signal receiving method, and a device are provided. A part that is of a first signal and that is carried on the kth subcarrier in the ith subcarrier group in N subcarrier groups is xi,nid(k), and a sequence {si,nid(k)} related to xi,nid(k) is one of enumerated sequences. The enumerated sequences are sequences with relatively good cross-correlation. Therefore, for two subcarrier groups, provided that selected {si,nid(k)} is two of the enumerated sequences, cross-correlation between signals carried in the two subcarrier groups can be ensured to be relatively good, thereby reducing interference between the signals and improving channel estimation performance.

Abstract: The present disclosure relates to signal processing methods and apparatus. One example method includes determining a first sequence {x(n)} based on a preset condition and a sequence {s(n)}, generating a reference signal of a first signal by using the first sequence, and sending the reference signal on a first frequency-domain resource. The preset condition is xn=y(n+M)mod K, where y n = A · e j × π × s n 8 , 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: This application provides an uplink power control method and apparatus. A network side device sends a plurality of pieces of configuration information of an RACH to UE, and indicates, by using a scheduling message of the RACH, identifier information of the configuration information of the RACH used by the UE. The UE calculates a transmit power of the RACH based on the configuration information that is of the RACH and that is corresponding to the identifier information, and sends a random access preamble to the network side device based on the transmit power of the RACH.
