The invention discloses a method and a device for feeding back hybrid channel state information, and a method and a device for processing feedback information. The method for feeding back the hybrid channel state information comprises the following steps of: estimating a channel state, and generating channel state information according to a result of channel estimation; measuring performance of the downlink according to the channel state information, and generating a control bit for indicating whether base station arrangement is modified or not according to the measurement result; when the control bit indicates that the base station arrangement is modified, sending the control bit and the channel state information to a base station; and when the control bit indicates that the base stationarrangement is not modified, only sending the control bit to the base station. By the method of the embodiment of the invention, whether the hybrid state information is fed back or not is judged according to the performance of the downlink, the expenditure of channel state information at transmitter (CSIT) feedback is reduced, and better downlink transmission performance is provided.

The invention provides a resource configuration method, a terminal and a network device, and solves the problem that a clear method for configuring semi-persistent resources does not exist yet when aplurality of different beams or transmission points are adopted to transmit and receive data to UE. The resource configuration method provided by the embodiment of the invention comprises the following steps: acquiring resource configuration information of semi-persistent resources, wherein the resource configuration information comprises identification information of a plurality of transmission carriers and resource allocation information corresponding to the identification information of each transmission carrier; and determining at least one of available resource position information of thetransmission carrier in each resource period and a hybrid automatic repeat request (HARQ) process number available in each resource period according to the resource configuration information of the semi-persistent resources. According to the invention, different semi-persistent resources are configured on different uplink transmission carriers and/or downlink transmission carriers, the utilization rate of the semi-persistent resources under multiple transmission carriers is improved, and meanwhile, the time delay generated by scheduling during data transmission is reduced.
