Method, device and medium for transmitting information

A method for transmitting information, performed by a base station, comprising:

• performing a downlink data transmission by using an idle channel resource after a successful channel detection of an unlicensed spectrum resource, comprising:
• determining a time-domain range of a transmission region, the transmission region being a region corresponding to a resource available to an unlicensed spectrum;
• and
• performing the downlink data transmission by using the unlicensed spectrum resource corresponding to the time-domain range,
• wherein the determining the time-domain range of the transmission region comprises:
• determining the time-domain range of the transmission region in accordance with preset time-domain resource configuration information;
• determining resource configuration information corresponding to a preceding downlink transmission resource for carrying the downlink data transmission, the resource configuration information at least including:
• time-domain resource configuration information;
• determining a scheduling instruction for the preceding downlink transmission resource according to the resource configuration information;
• sending the scheduling instruction to a terminal to enable the terminal to acquire target information sent by the base station from buffered data information according to the scheduling instruction;
• in response that the preset time-domain resource configuration information is time-domain resource configuration information of a first-type at a time when scheduling the preceding downlink transmission resource, which is appointed by the system;
• the determining the scheduling instruction for the preceding downlink transmission resource according to the resource configuration information comprises:
• determining an information field configured to indicate the preset time-domain resource configuration information;
• carrying indication information corresponding to the time-domain resource configuration information of the first-type in the information field, and generating the scheduling instruction.

A terminal, comprising:

• a processor;
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• buffer data information carried by an unlicensed spectrum resource;
• acquire a target scheduling instruction issued by a base station, the target scheduling instruction being configured to indicate resource configuration information of a preceding downlink transmission resource, and the preceding downlink transmission resource referring to the unlicensed spectrum resource that has completed transmission for downlink data before the base station issues scheduling information on the resource;
• acquire target information sent by the base station from the buffered data information according to the target scheduling instructions;
• wherein the processor is configured to acquire the target scheduling instruction by:
• receiving a scheduling instruction issued by the base station;
• determining whether a current scheduling instruction includes the resource configuration information of the preceding downlink transmission resource;
• and
• determining that the current scheduling instruction belongs to the target scheduling instruction in response that the current scheduling instruction includes the resource configuration information of the preceding downlink transmission resource;
• wherein the processor is configured to acquire target information sent by the base station from the buffered data information according to the target scheduling instruction by:
• determining a time-frequency range of the preceding downlink transmission resource according to the resource configuration information of the preceding downlink transmission resource;
• and
• parsing the target information from the buffered data information corresponding to the time-frequency range.
