Information sending method and receiving method, information sending apparatus and receiving apparatus, and storage medium

A method for receiving information in a direct-connection communication scenario, comprising:

• determining, by a receiving device, a plurality of candidate frequency-domain locations at which a sending device sends control information, wherein the control information occupies a number of m of different frequency-domain resources in a frequency-division multiplexing manner for repetitive transmission, a frequency-domain bandwidth of each of the m different frequency-domain resources is a first frequency-domain bandwidth, and m is an integer greater than 1;
• performing, by the receiving device, blind detection of the control information, according to the plurality of candidate frequency-domain locations;
• and
• receiving, after the control information is successfully received, by the receiving device, the user data on a target frequency-domain resource, according to the control information, wherein a frequency-domain bandwidth of the target frequency-domain resource is n times of the first frequency-domain bandwidth, the target frequency-domain resource comprises the m frequency-domain resources, n is an integer greater than 1, and m is less than or equal to n.

An apparatus for sending information in a direct-connection communication scenario, comprising:

• a processor;
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• determine a first frequency-domain bandwidth occupied by control information to be sent and a second frequency-domain bandwidth occupied by user data corresponding to the control information, wherein the second frequency-domain bandwidth is n times of the first frequency-domain bandwidth, and n is an integer greater than 1;
• occupy a number of m of different frequency-domain resources in a frequency-division multiplexing manner to repeatedly transmit the control information to a receiving device m times, wherein a frequency-domain bandwidth of each of the m different frequency-domain resources is the first frequency-domain bandwidth, and m is an integer less than or equal to n, and greater than 1;
• and
• occupy a target frequency-domain resource to send the user data to the receiving device, wherein a frequency-domain bandwidth of the target frequency-domain resource is the second frequency-domain bandwidth, and the target frequency-domain resource comprises the m different frequency-domain resources.
