    Abstract: Embodiments provide a communication method, a network device, and a terminal device. Under the method, a network device can send SRS configuration information of a first transmission resource and of a second transmission resource to a terminal device. The first transmission resource is a switching source carrier or bandwidth part. The second transmission resource is a switching destination carrier or bandwidth part. The SRS configuration information of the first and second transmission resource includes a first OFDM symbol set and a second OFDM symbol set respectively. Some and all symbols in the first set and second set may be used by the terminal device to send an SRS on the first and second transmission resource respectively. In various embodiments, the network device configures one or more symbols for the terminal device to transmit an SRS, so that high-frequency channel measurement can be better supported.

    Abstract: Provided are a method and an apparatus for canceling interference, to resolve a problem that performance of interference cancellation is poor because accuracy of equalizer coefficients obtained by a CMTS through calculation is not sufficiently high. A specific solution is as follows: (101) A CMTS calculates L equalizer coefficients of an L-tap filter according to a preamble sequence by using an adaptive algorithm, and performs adaptive equalization on a received signal by using the L equalizer coefficients, where L is a positive integer greater than 24; and (102) the CMTS selects K equalizer coefficients from the L equalizer coefficients, and sends a ranging response message carrying the K equalizer coefficients to a cable modem CM, so that the CM performs pre-equalization on a to-be-sent signal according to the received K equalizer coefficients, where K is a positive integer less than or equal to L.

    Abstract: The present invention discloses a method for indicating pilot state, a radio network controller. The method includes: acquiring, by an RNC, state information of a scheduled non-precoded pilot, where the state information of the scheduled non-precoded pilot indicates activated state or deactivated state of the scheduled non-precoded pilot; and sending, by the RNC, 4Tx MIMO mode configuration signaling to a UE, where the configuration signaling carries the state information of the scheduled non-precoded pilot, so that the UE acquires state of the scheduled non-precoded pilot according to the state information of the scheduled non-precoded pilot when being configured to 4Tx MIMO mode. The method for indicating pilot state and the radio network controller according to embodiments of the present invention can reduce physical-layer signaling overheads and reduce a delay in acquiring state of a scheduled non-precoded pilot by the UE in 4Tx MIMO mode.
