Method for acquiring uplink grant information, ue, and base station

User equipment (UE), comprising:

• a radio transceiver configured to obtain configuration signaling, wherein the configuration signaling comprises a code channel number of a downlink control channel;
• and
• a processor configured to monitor, on at least one code channel of the downlink control channel according to the configuration signaling, a channel that bears uplink grant information.

A method for acquiring uplink grant information, the method comprising:

• obtaining, by a base station, configuration signaling comprising a code channel number of a downlink control channel that UE needs to monitor;
• and
• sending, by the base station on at least one code channel of the downlink control channel according to the configuration signaling, a channel that bears uplink grant information of the UE, so that the UE monitors, on the at least one code channel of the downlink control channel, the channel that bears the uplink grant information.

A base station, comprising:

• a transceiver configured to obtain configuration signaling, wherein the configuration signaling comprises a code channel number of a downlink control channel that a user equipment (UE) needs to monitor;
• and
• a processor configured to send, on at least one code channel of the downlink control channel according to the configuration signaling by using the transceiver, a channel that bears uplink grant information of the UE, so that the UE monitors, on the at least one code channel of the downlink control channel, the channel that bears the uplink grant information.
