Title:
GUARD TIME INTERVAL DETERMINATION METHOD AND APPARATUS, COMMUNICATION APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/168579
Kind Code:
A1
Abstract:
The present disclosure relates to a guard time interval determination method and apparatus, a communication apparatus, and a storage medium. The guard time interval determination method comprises: determining a time domain range corresponding to an uplink subband for uplink transmission in a downlink slot; and determining a guard time interval before the time domain range or within the time domain range according to a pre-agreed rule. According to the present disclosure, a terminal can determine the time domain range corresponding to the uplink subband for uplink transmission configured for the terminal by a network device in the downlink slot, and then can determine the guard time interval before the time domain range or within the time domain range. The terminal does not expect to receive downlink data or send uplink data within the guard time interval, but can perform switching from downlink reception to uplink transmission, so as to ensure that the terminal has completed the switching when uplink transmission is required, such that uplink transmission can be performed in a timely manner, thereby avoiding interference with uplink transmission caused by delay in uplink transmission.
