Abstract: A method for determining time information is disclosed. The method includes: obtaining, by a network node, information sent by a terminal device; and determining, by the network node, at least one of the following based on the information: a first time interval between downlink scheduling and downlink data transmission, a second time interval between the downlink data transmission and a feedback message sent by the terminal device after the terminal device receives downlink data, and a third time interval between uplink scheduling and uplink data transmission, where the information may include at least one of a subcarrier spacing, an operating band, and a bandwidth that are supported by the terminal device, and further include a first smallest value and/or a second smallest value and/or a third smallest value corresponding to the at least one item. Therefore, flexibility and accuracy of determining the time information are improved.

Abstract: A timing advance determining method and a device are provided. In the method, a network device determines, based on a correspondence between a parameter set and a TA granularity, TA information used by a terminal on an occupied frequency domain resource, where the parameter set includes a subcarrier spacing and a cyclic prefix type of a symbol; the network device sends the TA information to the terminal; and the terminal determines, based on the correspondence between a parameter set and a TA granularity, a TA granularity corresponding to the frequency domain resource occupied by the terminal, and determines, based on the TA granularity and the TA information, a TA value used by the terminal on the occupied frequency domain resource.

Abstract: Embodiments described provide a data transmission method, a network device, and a terminal device. The method includes: sending, by a network device, control information corresponding to target data to a terminal device on a control resource, where the control resource and a data resource have a correspondence, and the control resource is used by the terminal device to determine the data resource on which the target data is received; and sending, by the network device based on the correspondence, the target data to the terminal device on the data resource. In the embodiments, after sending the control information corresponding to the target data on the control resource, the network device can send the target data on the data resource based on the correspondence between the control resource and the data resource, so that terminal devices having different bandwidth capabilities are able to receive the target data.

Abstract: The communication method includes: sending, by a CMTS (cable modem terminals stem), a reference signal within a first time period by using a valid subcarrier in a first spectrum, where the first time period is a time period within which none of CMs (cable modems) connected to the CMTS sends a signal in the first spectrum; performing, by the CMTS based on an interfering signal received by the CMTS within the first time period, channel interference estimation on a channel that is used during signal reception of the CMTS and that occupies the first spectrum, where the interfering signal is a signal obtained after the reference signal passes through the channel; and canceling, by the CMTS based on a result of the channel interference estimation, interference from a first signal received by the CMTS to a second signal received by the CMTS.

Abstract: The present invention provides a power adjustment method, a network management system, a CMTS, and a CM. The power adjustment method includes: obtaining, by a network management system, a first SNRCM between two CMs connected to a CMTS, where the first SNRCM represents a signal ratio of a signal sent by the CMTS to a first CM and received by the first CM to a signal sent by a second CM to the CMTS and received by the first CM; and sending, by the network management system, indication information to the CMTS based on the first SNRCM, and a first relationship between an SNRCM and a transmit power at which the CMTS sends a signal to the CM.

Abstract: The present disclosure provides example channel parameter estimation methods and related apparatuses. In one example method, a cable modem (CM) obtains a second data frame through a downlink channel between the CM and a cable modem termination system (CMTS). The second data frame is generated after a first data frame sent by the CMTS is modulated through the downlink channel, a zero-bit-loaded symbol of the first data frame includes no valid codeword, but includes a zero-bit-loaded NCP and an idle codeword identified by the zero-bit-loaded NCP, and the idle codeword includes a data sequence used for channel parameter estimation. The CM can estimate a channel parameter of the downlink channel based on a data sequence in an obtained zero-bit-loaded symbol of the second data frame and the data sequence in the zero-bit-loaded symbol of the first data frame.
