Abstract: A signal sending method and apparatus, to improve channel estimation performance are provided. A reference signal is sent on one or more consecutive symbols, and modulation data is sent on an adjacent symbol previous to the one or more consecutive symbols in time domain and an adjacent symbol next to the one or more consecutive symbols in time domain. A sum of the modulation data carried in the symbol previous to the one or more consecutive symbols and the modulation data carried in the symbol next to the one or more consecutive symbols is zero or the modulation data is the same. According to the application, after time-domain filtering, the reference signal is not interfered with by the adjacent modulation data, so that channel estimation performance can be ensured.

Abstract: The present disclosure provides example communication methods and example communication apparatuses for non-coherent transmission. One example communication method includes determining P1 first symbols based on a first to-be-modulated bit, where P1=M×N1, N1 is a quantity of resource units used to carry the P1 first symbols, M is a positive integer, and N1 is an integer greater than 1. P2 second symbols are determined based on a second to-be-modulated bit, where P2=M×N2, and N2 is an integer greater than 1. P3 third symbols are determined based on the P1 first symbols and the P2 second symbols, where P3=M×N3, N3 is a quantity of resource units used to carry the P3 third symbols, and N3 is less than or equal to N2. The P1 first symbols and the P3 third symbols are sent.

Abstract: A method, device, and storage medium are disclosed that determine beam information of an antenna port for a frequency domain resource not used for transmitting uplink data and/or uplink control information. In one embodiment, a first device determines, based on first configuration information, that a beam for sending a first uplink reference signal on a first antenna port is also a beam for sending a second uplink reference signal on a second antenna port, and sends the first uplink reference signal on the first antenna port. Beam information of the first antenna port can be determined based on beam information of the second antenna port, and the first uplink reference signal can be sent based on the determined beam information of the first antenna port. This can spare beam configuration performed by a network side for the first frequency domain resource, and reduce overheads for transmitting configuration information.

Abstract: A signal transmission method and apparatus are provided, to resolve a problem that because a PAPR of a signal is comparatively high, a waveform distortion of the signal is comparatively serious after power amplification is performed on the signal by using a PA. The method includes: separately performing phase rotation on M pieces of modulated data to obtain M pieces of phase-rotated data, where a phase factor for performing phase rotation on the M pieces of modulated data is determined based on M. The method further includes: determining time domain data based on the M pieces of phase-rotated data, and sending the time domain data to a receive end.

Abstract: Embodiments of this application provide a non-coherent data transmission method and a communication apparatus. In the method, a transmit end device determines, in a first constellation, a first constellation point corresponding to first to-be-modulated bits, where the first constellation point corresponds to P first symbols, P=M*N, M is a positive integer, and N is an integer greater than 1; and sends the P first symbols on N resource units by using M antenna ports, or sends P second symbols determined based on the P first symbols, and foregoes sending demodulation reference signals of the P first symbols or the P second symbols. In the method, a constellation is designed, and each constellation point in the constellation corresponds to a plurality of resource units so that data can be transmitted with no need to transmit a reference signal, and only the data needs to be transmitted.
