Abstract: Embodiments of this disclosure provide a communication method and apparatus, a terminal device, a network device, and a medium. In the method, the terminal device receives first scheduling information from the network device, where the first scheduling information indicates a set of shared channel transmission occasions and a first beamforming manner of a shared channel. The terminal device receives second scheduling information from the network device, where the second scheduling information indicates a control channel transmission occasion and/or a second beamforming manner of a control channel. If the terminal device determines that time domain resources of the control channel transmission occasion and one or more shared channel transmission occasions in the set of shared channel transmission occasions at least partially overlap, the terminal device determines at least one shared channel transmission occasion from the set based on at least one of the first beamforming manner and the second beamforming manner.

Abstract: This application provides a data transmission method, terminal device, and network device. The method includes: sending, by a terminal device, at least one precoded reference signal on at least one reference signal resource corresponding to a first PRG, where different precoding matrixes are used for different reference signals, and the first PRG is a PRG used to transmit a reference signal; receiving, by the terminal device, resource indication information, where the resource indication information indicates a reference signal resource that is corresponding to a second PRG and that is in the at least one reference signal resource, and the second PRG is a PRG used to transmit a physical uplink shared channel (PUSCH); and sending, by the terminal device, a precoded PUSCH on the second PRG based on the resource indication information, where a precoding matrix used for the PUSCH is a precoding matrix used for a reference signal sent on the reference signal resource corresponding to the second PRG. In this way, a precoding matrix used to transmit the PUSCH on the second PRG can be effectively selected.

Abstract: This application provides a reference signal transmission method and an apparatus, used in a multipoint coordination transmission scenario. In one example method, a frequency domain resource that carries a target reference signal in a frequency domain resource or a time domain resource that is associated with each QCL assumption may be separately determined, and then the target reference signal carried on the frequency domain resource that is associated with the QCL assumption is separately received by using the corresponding QCL assumption.

Abstract: This disclosure provides example wireless communication methods and communication apparatuses. One example method includes that a network device sends indication information of m first symbol groups used for repeated transmission of a first transport block (TB) to a terminal. The terminal and the network device determine, according to a same rule, a quasi co-location (QCL) assumption corresponding to each of second symbol groups actually used when the first TB is sent or received.

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.
