Abstract: The present invention provides a method for transmitting and receiving a control channel, a base station, and a user equipment. The method for transmitting a control channel includes: determining m PRB pairs used for transmitting a control channel to be transmitted; when a distributed transmission mode is used for transmission, determining an aggregation level L of the control channel to be transmitted; determining, according to the aggregation level L, a first control channel candidate at the aggregation level L; and placing control information of the control channel to be transmitted, on physical resources to which the first control channel candidate is mapped, and transmitting the control information. The present invention improves multiplexing efficiency of control channels of different modes.

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.
