Abstract: A rate matching method including: determining a receiving capability of a receive end, where the receiving capability is used to indicate a maximum data processing volume of the receive end in a first transmission time, and/or the receiving capability is used to indicate a maximum data buffer volume of the receive end in a first transmission time; the first transmission time is used to transmit a first transport block to which a first code block belongs; determining NCB based on the receiving capability, where NCB represents a code block size used for rate matching; performing rate matching on the first code block based on NCB. The receive end can adjust, based on a processing capability and/or a buffer capability that are/is of the receive end in a period of time, the code block size used for rate de-matching, to avoid insufficiency in processing capability and/or buffer overflow at the receive end.

Abstract: This application provides a communication method, a communications apparatus, and a readable storage medium. The communication method includes: determining a second moment based on a first moment and a first processing delay, where the first moment is an estimated earliest moment at which a terminal device can send feedback information for first downlink data, the first processing delay is an estimated delay in processing second downlink data by the terminal device, a time unit used by the second downlink data is after a time unit used by the first downlink data, and the second moment is after the first moment; and sending indication information to the terminal device, where the indication information is used to indicate the terminal device to send feedback information for the second downlink data at the second moment or after the second moment. This application can avoid increasing processing resources, to save resources.

Abstract: A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

Abstract: Embodiments of this application disclose a method, an apparatus, and a system for positioning a terminal device. Location measurement data for a to-be-positioned terminal device is obtained by a terminal-side measurement function entity and/or an access-side measurement function entity, where the location measurement data includes a channel estimation and/or a channel impulse response that are/is obtained based on a corresponding downlink/uplink reference signal. The terminal-side measurement function entity and/or the access-side measurement function entity report/reports the location measurement data to a positioning service function entity in a network, so that the positioning function entity can estimate a location of the terminal device based on the location measurement data, thereby positioning the terminal device and improving positioning accuracy. This technical solution can be applied to both a single-base-station-based positioning environment and a multi-base-station-based positioning environment, to position the terminal device.
