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 , 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 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.

Abstract: This application provides a physical broadcast channel sending/receiving method and an apparatus. In the method, after receiving two broadcast channel signals on two corresponding physical broadcast channels at two time-frequency resource locations, the terminal device determines that information other than an offset of a corresponding time-frequency resource location is the same in two pieces of broadcast information carried in the two broadcast channel signals, obtains a time offset difference between the foregoing two time-frequency resource locations, and generates a scrambling sequence based on the time offset difference; and the terminal device separately descrambles the two broadcast channel signals based on the scrambling sequence and a preset scrambling sequence, thereby implementing joint decoding on the two broadcast channel signals, to obtain one piece of broadcast information.

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: 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.

Abstract: In response to a user equipment (UE) sending data to a first network side device over a first channel and to a second network side device over a second channel, a method includes determining that the first channel separately overlaps the second channel and a third channel. The method further includes allocating, according to priorities of the first channel and the second channel, a first transmit power to the first subframe j and a second transmit power to the second subframe i. The first transmit power is less than or equal to a first power upper limit. A sum of the first transmit power and the second transmit power is less than or equal to a first threshold. A sum of third transmit power of the third subframe i+1 and the first power upper limit is less than or equal to a preset threshold.
