Abstract: This application provides a method for reporting a terminal device capability and a communications apparatus. The method includes: The terminal device generates first indication information and sends the first indication information to a network device. The first indication information is used to indicate one or more frequency domain parameters and one or more of the following capability parameters associated with each frequency domain parameter: a port quantity, a spatial domain parameter, a reference signal resource quantity, and a total port quantity. The frequency domain parameter is used to indicate a maximum quantity of frequency domain units that can be supported by the terminal device. The frequency domain unit is a frequency domain unit based on which the terminal device feeds back a PMI. Each capability parameter group may be used to indicate one combination of a plurality of parameters that can be supported by the terminal device.

Abstract: A service flow scheduling method and apparatus, and a system. When transmission quality of a service flow with a higher priority does not meet a service level requirement corresponding to the service flow, a first network device adjusts, to a first threshold, a transmission rate threshold of an HQoS model for a service flow with a lower priority, where the first threshold is less than a current data transmission rate of the service flow with a lower priority. By performing traffic shaping on the service flow with a lower priority, a bandwidth resource of a downlink port of the first network device may give way to the service flow with a higher priority, to ensure that the service flow with a higher priority meets the service level requirement of the service flow with a higher priority.

Abstract: The present disclosure relates to reference signal resource configuration methods and apparatus. In one example reference signal resource configuration method, a terminal receives sounding reference signal (SRS) resource configuration information from a base station. In response to determining that at least two SRS resources indicated by the SRS resource configuration information are located on a same orthogonal frequency division multiplexing (OFDM) symbol, the terminal maps one of the at least two SRS resources to the OFDM symbol.
