In a specific solution, a first network device sends a first signal to a second network device. The first signal is used for the second network device to determine a first measurement pilot according to the first signal, and send the first measurement pilot to the first network device. The first network device receives the first measurement pilot sent by the second network device, and measures the first measurement pilot to obtain first CSI. The first CSI includes at least one of a CQI, a PMI, an RI, or port selection information.

    Abstract: Methods and apparatus are provided for transmitting channel quality information. User equipment receives a control signaling for uplink scheduling. The control signaling for uplink scheduling includes at least one modulation and coding scheme (MCS) field, a channel quality information request field, and a resource block allocation field indicating the number of resource blocks (RBs), NRB, allocated to the user equipment for transmitting the channel quality information. When the channel quality information of multiple downlink carriers is requested, the user equipment transmits only the channel quality information on the uplink shared channel according to the allocated RBs to the base station if: the MCS bit field corresponding to one transport block indicates a MCS corresponding to a retransmitted data packet; the request bit field indicates a request for the channel quality information; and the NRB is equal to or less than a threshold which is related to the number of the downlink carriers and a maximum number of RBs which can be allocated for transmitting only the channel quality of one downlink carrier.
