Abstract: The present invention relates to the field of communications technologies, and in particular, to a CSI reporting method, a CSI receiving method, and an apparatus, to resolve a technical problem that PUCCH resource overheads are relatively large during CSI reporting. In embodiments of the present invention, at least two PUCCH resources are configured for each downlink carrier group. CSI that needs to be reported in one uplink subframe may be obtained, and a format of a corresponding PUCCH resource is determined according to the to-be-reported CSI. For example, the determined format is referred to as a first format. Then, all of the to-be-reported CSI is reported after being added to a first first-format PUCCH resource.

Abstract: The present invention discloses a downlink control information sending method and device, and a downlink control information receiving method and device. The sending method includes: sending, by a base station device, downlink control information DCI on a physical downlink control channel PDCCH of a downlink subframe, where the DCI is used to instruct user equipment UE to receive physical downlink shared channel PDSCH information in an uplink subframe; and sending the PDSCH information in the uplink subframe. In this way, the base station can effectively schedule an uplink subframe, and a purpose of transmitting a downlink service by using an uplink subframe is achieved, which not only improves utilization of a wireless spectrum resource corresponding to the uplink subframe, but also effectively diverts load pressure of a wireless spectrum resource corresponding to a downlink subframe. Therefore, overall utilization of wireless spectrum resources of a system is improved.

Abstract: This application provides a communication method and a communication apparatus. In the method, a terminal device obtains first information, where the first information is associated with a mode of communication between a first network device and the terminal device and/or a mode of communication between a second network device and the terminal device, and the communication mode includes any one of the following: whether uplink transmission is activated, or whether downlink transmission is activated; and the terminal device determines to communicate with the first network device and/or the second network device based on the first information. In other words, in a network device, an uplink transmission module configured to receive an uplink signal is disabled, or a downlink transmission module configured to send a downlink signal is disabled.

Abstract: A method and an apparatus for assisting a terminal in measuring are provided, which relate to the field of communications network technologies and may implement correct measurement on signal strength of a micro base station, thereby preventing UE from incorrectly determining the signal strength of the micro base station. In embodiments of the present invention, a first base station receives a measurement result for a second base station sent by UE, where the first base station provides a service for the UE; the first base station determines, according to the measurement result, whether a handover operation needs to be started; when the handover operation needs to be started, the first base station instructs the second base station to start up, and hands over the UE to the second base station for a service provided by the second base station.
