AI Technical Summary

⚠Technical Problem

In a half-duplex FDD system, uplink and downlink data from user equipment may conflict at the same time, resulting in data loss. Existing technologies are unable to effectively avoid such conflicts.

⚗Method used

By introducing a time offset, the uplink data transmission of user equipment is delayed, allowing it to transmit only after receiving downlink data, thus avoiding uplink and downlink data conflicts. This time offset can be at the beam coverage area level, determined based on the propagation delay range from the satellite to the user equipment.

🎯Benefits of technology

It effectively avoids uplink and downlink data conflicts, saves network equipment computing resources, and improves the accuracy and efficiency of data transmission.

Abstract

The present application discloses a collision avoidance method and a communication apparatus. The method comprises: receiving first control information (DCI), the first DCI being used for indicating a time domain resource of uplink data and a first time offset, the first time offset being a time length at least reserved between a first symbol and a second symbol, the first symbol being a first symbol of scheduled uplink data, and the second symbol being the last symbol of last scheduled downlink data before the scheduled uplink data; and on the basis of the time domain resource of the uplink data and the first time offset, sending the uplink data. Use of the described method can avoid conflicts between uplink and downlink data.
