Abstract: Example interference measurement methods and apparatus are described. One example method includes that a terminal device receives configuration information of an interference measurement resource from a network side device. The terminal device performs first interference measurement by using a first measurement resource. The first measurement resource is a proper subset of the interference measurement resource. A quantity of resource elements of the first measurement resource that are located in a same symbol is M, where M≥2. A spacing in frequency domain between two adjacent resource elements of the M resource elements of the first measurement resource that are located in the same symbol is more than one subcarrier.

Abstract: A signal sending and receiving method includes: receiving, by a terminal device, at least one piece of resource configuration information for determining N reference signal resource groups, and each of the N reference signal resource groups includes at least one reference signal resource; and sending a reference signal on a resource in an ith reference signal resource group in the N reference signal resource groups by using a jth antenna group corresponding to the ith reference signal resource group, where the jth antenna group includes at least one antenna. The N reference signal resource groups correspond to N antenna groups, and any two of the N antenna groups are different.

Abstract: This application discloses a resource indication method, a network device, and a terminal device, to improve utilization of a resource mapped to a DMRS port. The method includes: sending, by a network device, configuration information to a terminal device, so that the terminal device determines, based on the configuration information, that a second resource in first resources is used to transmit first information or that a third resource in first resources is not used to transmit first information, where the first resources are resources mapped to a DMRS port. In this way, the terminal device can multiplex the resources mapped to the DMRS port. When some of the first resources are not used to transmit a DMRS, the resources may be indicated to determine whether the resources may be used to transmit the first information, for example, the first information may be data, control information, or other information different from DMRS information, thereby ensuring maximum use of the resources mapped to the DMRS port, and improving resource utilization.

Abstract: This application provides an information transmission method and a communications device. A first communications device sends first indication information to a second communications device, where the first indication information indicates a frequency resource used by the second communications device to send data in a time unit and a frequency resource used by the second communications device to receive data in the time unit, the frequency resource used to send data and the frequency resource used to receive data belong to a same frequency band, the frequency resource used to send data and the frequency resource used to receive data are differentiated based on frequencies in the time unit, and the frequency band is a segment of continuous frequency resources in frequency domain. In the foregoing information transmission method, the first communications device can flexibly allocate the frequency resources based on a network requirement, thereby improving resource utilization.

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.
