    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: A method for implementing Customized Ringing Signal (CRS) services is provided. The method includes: receiving a call request initiated by a caller terminal; obtaining a policy of playing a CRS tone according to the call request, where the policy is a policy of playing a CRS tone, namely, a caller CRS tone or a callee CRS tone, or a policy of filtering the CRS tone; and playing the CRS tone to a callee according to the policy. By setting a policy of playing the CRS tone to the callee in the network or the callee terminal, the users enjoy the CRS services at their own discretion.

    Abstract: This application provides a method for reporting port information, a terminal device, and a network device. The method includes: determining, by a terminal device, an uplink signal, where the uplink signal includes information about a phase tracking reference signal PTRS port of the terminal device, or the uplink signal includes information about the PTRS port and information about a DMRS port, or the uplink signal includes a correspondence between the PTRS port and the DMRS port; and sending, by the terminal device, the uplink signal to a network device. In embodiments of this application, the terminal device reports the uplink signal to the network device, so that the network device does not need to configure different PTRS ports for DMRS ports, to avoid configuring excessive PTRS ports, thereby saving PTRS port resources.

    Abstract: This application discloses a reference signal transmission method and apparatus. A base station sends a first reference signal and a second reference signal, where the first reference signal is sent by using a first group of antenna ports, the second reference signal is sent by using a second group of antenna ports, the first group of antenna ports include at least two antenna ports, and the second group of antenna ports include at least two antenna ports; and second reference signals are mapped to a same time-frequency resource, or second reference signals sent on the at least two antenna ports in the second group of antenna ports are mapped to a same time-frequency resource. According to the foregoing solution, second reference signals transmitted on different ports are mapped to a same time-frequency resource, thereby reducing a quantity of occupied time-frequency resources.
