Abstract: Method and apparatus are provided for mapping and detecting a control channel. For the same aggregation level, according to a signaling length of a control channel corresponding to a component carrier, a corresponding search space is determined for at least two control channels that have the same signaling length, so as to enable the at least two control channels that have the same signaling length to use the same search space. The at least two control channels having the same signaling length are mapped to the determined corresponding search space. Therefore, conflicts between the control channels are reduced, and the number of times of blind detection of the control channels is also reduced.

Abstract: In a signal transmission method and apparatus, a network device sends scheduling information of at least one of two carriers whose communication directions are opposite on a target OFDM symbol; a terminal device performs channel transmission of a target carrier on the target OFDM symbol based on the scheduling information, where the target carrier is one of carriers that are of the two carriers whose communication directions are opposite and that have channel transmission on the target OFDM symbol; and the network device performs channel transmission on the target OFDM symbol and the target carrier. A time domain resource may be allocated to a carrier on which transmission scheduling is currently performed, thereby improving transmission resource utilization and reducing a waiting delay.

Abstract: This application provides a random access method, a communication apparatus, and a communication system. The method includes: A base station sends first indication information to a terminal, to indicate that statuses of one or more RACH resources in a RACH resource set are available or unavailable, where each RACH resource in the RACH resource set corresponds to one common signal in a common signal set, and each common signal in the common signal set corresponds to one or more RACH resources in the RACH resource set. The terminal selects an available first RACH resource from the RACH resource set based on the first indication information, and sends a RACH signal to the base station on the first RACH resource.
