Abstract: This application provides a reference signal indication method and apparatus. The method includes: transmitting, by a terminal device, a PTRS to a network device based on a time domain density; and receiving, by the network device, the PTRS transmitted by the terminal device based on the time domain density, where the time domain density is a density in a discrete Fourier transform spread orthogonal frequency division multiplexing DFT-s-OFDM waveform. Therefore, successful PTRS transmission can be ensured.

Abstract: Example reference signal transmission methods and apparatus are described. In one example method, a base station divides a transmission bandwidth into a plurality of frequency domain units, and sends reference signal sending configuration information to a terminal. The terminal transmits a reference signal on one or more frequency domain units. The one or more frequency domain units and another frequency domain unit form a part of the transmission bandwidth supported by the base station. The terminal sends the reference signal on the one or more frequency domain units to the base station based on the reference signal sending configuration information.

Abstract: An embodiment of this application provides a method for transmission in a time interval. The time interval includes one or more first time units and one or more second time units. The one or more first time units are used to transmit a first-type signal, and a quantity of first time units is associated with a quantity of first-type signals. The one or more second time units are used to transmit a second-type signal. In the method, a receiving node may obtain time unit information, where the time unit information is used to obtain a location of the one or more second time units, that is, determine a time domain location of the second-type time-frequency resource in the time interval. Then, the receiving node may receive or send the second-type signal on the second-type time-frequency resource.

Abstract: A first communication device determines a DMRS sequence based on a cover code in a set of cover codes; and thereafter determines a DMRS by mapping the DMRS sequence onto one or more PRBs. The cover code is dependent on a DMRS antenna port index, and cover codes in the set of cover codes are orthogonal to each other in each PRB, and wherein a maximum correlation power between two cover codes in the set of cover codes is larger than 0 in each half PRB. Finally, the first communication device transmits the DMRS via a DMRS antenna port having DMRS antenna port index to a second communication device which receive the DMRS and associated data signal. The second communication device demodulates the associated data signal based on the received DMRS and the DMRS sequence.

Abstract: This application relates to the field of wireless communications technologies, and in particular, to a sounding reference information (SRS) transmission method, to resolve a problem of when to transmit an SRS. In the method, user equipment (UE) receives SRS resource configuration information sent by a base station. The UE receives downlink control information (DCI) sent by the base station. The UE sends an SRS in a determined slot and symbol, where the determined symbol is determined by the UE based on the SRS resource configuration information.
