Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives an identifier of a filtering protocol version from an access network device, and then sends first capability information of the terminal device to the access network device based on the filtering protocol version. In this method, the terminal device may report capability information based on the filtering protocol version sent by the access network device. Compared with a manner in which the terminal device directly reports the capability information, this method can effectively reduce a communication problem caused by mismatch between a protocol version supported by the terminal device and a protocol version supported by the access network device and/or a protocol version supported by a core network device.

Abstract: Embodiments provide a method for generating a random access channel ZC sequence, and an apparatus. A method for generating a random access channel ZC sequence includes: generating, by a base station, notification signaling, where the notification signaling instructs user equipment (UE) to generate a random access ZC sequence by using a second restricted set in a random access set; and sending, by the base station, the notification signaling to the UE, so that the UE generates the random access ZC sequence by using the second restricted set, where the random access set includes an unrestricted set, a first restricted set, and the second restricted set; and the second restricted set is a random access set that the UE needs to use when a Doppler frequency shift of the UE is greater than or equal to a first predetermined value.

Abstract: This application relates to the field of mobile communications, and in particular, to technologies of obtaining channel state information in a wireless communications system. In a channel information obtaining method, a base station obtains channel state matrix information of some channels based on uplink reference information sent by a terminal and partial channel state information of channels between the base station and the terminal, to obtain channel state matrix information of the channels between the base station and the terminal. Base on this method, relatively complete channel state matrix information of the channels between the base station and the terminal can be obtained. This helps the base station select an appropriate parameter to transmit data to the terminal without causing an additional delay, performance loss, or cost increase, or consuming more time-frequency resources used for the uplink reference signal.
