UPLINK SIGNAL CONTROL METHOD AND APPARATUS

摘要

The present invention relates to the field of communications technologies, and in particular, to an uplink signal control method and apparatus, which are used to resolve a problem that when UE is not within primary carrier signal coverage of a micro cell, the micro cell cannot control uplink transmission of the UE on a primary carrier. The uplink signal control method of the present invention includes: determining, by a first network device, uplink control configuration information for user equipment (UE), where the uplink control configuration information includes information about a control channel occupied by control information, which is transmitted by a second network device on a second carrier, for controlling an uplink transmission action of the UE on a first carrier; and notifying, by the first network device, the uplink control configuration information to the second network device, and sending the uplink control configuration information to the UE or instructing the second network device to send the uplink control configuration information to the UE.
