Information transmission method, device, and system

An apparatus, comprising:

• first circuitry configured to:
• when a terminal and a network device need cross-carrier scheduling, receive downlink control information from the network device in a first transmission time interval of a scheduling cell, wherein the downlink control information indicates radio resource allocation information in K consecutive second transmission time intervals of a scheduled cell, and K is an integer greater than or equal to 2;
• and
• second circuitry configured to perform communication with the network device according to the downlink control information.

A network device, comprising:

• first circuitry configured to:
• when a terminal and a network device need cross-carrier scheduling, send downlink control information to the terminal in a first transmission time interval of a scheduling cell, wherein the downlink control information indicates radio resource allocation information in K consecutive second transmission time intervals of a scheduled cell, and K is an integer greater than or equal to 2;
• and
• second circuitry configured to perform communication with the UE.
