Abstract: Embodiments of the present invention provide a control information sending method, receiving method, and device. The control information sending method includes: determining a first subframe of a first radio frame on a first carrier, where the first subframe includes a control region; sending control information in the control region of the first subframe of the first radio frame to a user equipment, where the control information includes a PDCCH; and sending an ePDCCH in a second subframe of the first radio frame to the user equipment. According to the embodiments of the present invention, when control information borne on an ePDCCH cannot be sent in a first radio frame, a PDCCH can still be sent to a user equipment through a control region in a first subframe, thereby achieving purposes of performing uplink/downlink scheduling for the user equipment and downlink feedback for uplink data of the user equipment.

Abstract: Methods and apparatuses for sending a multicast control channel are provided. One example method includes a terminal device receiving first configuration information, where the first configuration information indicates N modification periods, and N is an integer greater than 1. The terminal device determines, based on the first configuration information, a modification period corresponding to a first service, and monitors a modification notification of an MCCH based on the modification period corresponding to the first service. Therefore, in some instances, services with different latency sensitivities can correspond to different modification periods to meet latency requirements of different services and ensure an electricity saving effect of the terminal device.
