Electronic device and method for use in radio communication, and computer-readable storage medium

An electronic apparatus for wireless communications, comprising:

• processing circuitry, configured to:
• determine a plurality of partial sensing windows separated from each other in a time domain,
• wherein in the plurality of partial sensing windows, a user equipment performing sidelink communications senses at least a part of time-frequency resources in a resource pool for the sidelink communications;
• and
• determine a partial sensing-resource selection window and one or more resource selection windows,
• wherein the partial sensing-resource selection window is a time-frequency window defined by a plurality of previous partial sensing windows after triggering resource selection, an occupancy state of time-frequency resources in the partial sensing-resource selection window is known to the user equipment, and the user equipment selects time-frequency resources in the one or more resource selection windows to perform the sidelink communications,
• wherein the partial sensing-resource selection window covers the one or more resource selection windows,
• wherein, in a case that the user equipment performs a hybrid automatic retransmission request (HARQ) transmission, the processing circuitry is further configured to determine, based on a maximum number of times of transmission of a single data packet in the HARQ transmission, a lower limit of a time domain size of the partial sensing-resource selection window.
