Abstract: This application discloses a reference signal transmission method and an apparatus. A network node sends reference signals by mapping the reference signals to at least one resource unit, where the at least one resource unit includes a plurality of sub-resource units; and the network node receives, from the terminal, measurement information related to part of the plurality of sub-resource units. The terminal selects, based on configuration information of the reference signals, part of the measurement information to report, so that a quantity of channel resources occupied by the measurement information is reduced.

Abstract: This application discloses a reference signal configuration method and apparatus. Before a network device sends reference signals aperiodically, the network device sends configuration information to a terminal device, where the configuration information is used to indicate a timeslot offset of one or more reference signal resource sets. Therefore, the network device can flexibly send reference signals in different timeslots, thereby reducing a quantity of times of reference signal triggering and measurement result reporting, and improving efficiency of a communications system.

Abstract: Embodiments provide a method for transmitting a reference signal between a base station and a terminal. In this method, a parameter is determined by a terminal based on frequency domain location information of a frequency domain resource unit. The parameter is used to determine a sequence of the reference signal, and the reference signal is carried on the frequency domain resource unit. The reference signal can be sent to the base station by the terminal. In some embodiments, the reference signal sent by the base station can be received by the terminal. According to this method, a peak-to-average power ratio when a single terminal sends data to a base station can be reduced, and communication interference between different cells can be canceled or reduced as much as possible.

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 demodulation reference signal (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.
