Abstract: The application pertains to determining a rank of channel loss extent. A base station sends to a terminal a signaling indicating that there are N ranks of channel loss extent. Each rank has a corresponding number of random access preamble repetitions. The base station receives from the terminal device one or more transmissions of a random access preamble in a first number of repetitions of the random access preamble. The base station determines the rank of channel loss extent according to a random access preamble group in which the received random access preamble is located, or the first number of repetitions of the received random access preamble. A channel loss is a reference signal received power (RSRP). After determining the rank of channel loss extent, the base station determines a second number of repetitions corresponding to the determined rank of channel loss extent, for sending or receiving uplink/downlink information.

Abstract: A control information communication method, a base station, and user equipment are provided. A determination is made whether downlink control information (DCI) is used for multicast transmission or for paging. When the DCI is determined to be used for multicast transmission, the DCI is scrambled by using a single cell radio network temporary identifier (SC-RNTI). The DCI includes indication information and scheduling information, the indication information indicating whether a multicast control channel is updated. When the DCI is determined to be used for paging, the DCI is scrambled by using a paging radio network temporary identifier (P-RNTI). The scrambled DCI can be sent to user equipment by using a first downlink control information format.
