Cross-subband or cross-carrier scheduling method, base station and user equipment

A cross-subband or cross-carrier scheduling method, comprising:

• receiving downlink control information transmitted by a base station on a first subband or a first carrier, where the downlink control information comprises an identification number of a second subband or a second carrier allocated for a user equipment and a first start symbol and a first end symbol for scheduling the user equipment to transmit and receive data using a time-frequency resource on the second subband or the second carrier, wherein the downlink control information further comprises a scheduling indication for indicating the user equipment to detect scheduling information after a predetermined time;
• and
• transmitting or receiving data using the time-frequency resource on the second subband or the second carrier based on the downlink control information.

A base station, comprising:

• a determining circuitry, configured to determine a first start symbol and a first end symbol for scheduling a user equipment to transmit and receive data using a time-frequency resource on a second subband or a second carrier, based on a first numerology corresponding to a first subband or a first carrier and a second numerology corresponding to the second subband or the second carrier;
• and
• a transmitting circuitry, configured to transmit downlink control information to the user equipment on the first subband or the first carrier, so that the user equipment can transmit and receive data using the time-frequency resource on the second subband or the second carrier according to the downlink control information, where the downlink control information comprises an identification number of the second subband or the second carrier allocated for the user equipment and the start symbol and the first end symbol determined by the determining circuitry for scheduling the user equipment to transmit and receive data using the time-frequency resource on the second subband or the second carrier.

A user equipment, further comprising:

• a receiving circuitry, configured to receive downlink control information transmitted by a base station on a first subband or a first carrier, where the downlink control information comprises an identification number of a second subband or a second carrier allocated for a user equipment and a first start symbol and a first end symbol for scheduling the user equipment to transmit and receive data using a time-frequency resource on the second subband or the second carrier, wherein the downlink control information further comprises a scheduling indication for indicating the user equipment to detect scheduling information after a predetermined time;
• and
• a data transceiving circuitry, configured to transmit or receive data using the time-frequency resource on the second subband or the second carrier based on the downlink control information received by the receiving circuitry.
