AI Technical Summary

Technical Problem

In wireless communication systems, transmission conflicts may occur when multiple terminal devices use the same uplink resource, resulting in low data packet transmission success rate and difficulty in properly transmitting uplink data and receiving downlink data, which can easily lead to abnormal situations.

Method used

By selecting M transmission resources in the transmission window, ensuring that these resources do not overlap with the downlink reception window in the time domain, and canceling data packet transmission or adjusting the timing of feedback information reception when a collision is detected, the data packet transmission and feedback process are optimized by using scrambling codes and indication information processing.

Benefits of technology

It effectively avoids conflicts between uplink transmission and downlink reception, improves data packet transmission success rate and communication reliability, and reduces power consumption and access latency.

Abstract

A transmission control method, apparatus, and system are disclosed, capable of rationally performing uplink transmission and downlink reception to avoid anomalies, and applicable to NTN systems, such as satellite communication systems. The method includes: a first communication device determining M transmission resources within a first transmission window, the M transmission resources being used to transmit M data packets; wherein each of the M data packets is associated with a downlink reception window, the downlink reception window being used to receive feedback information for the data packets. The method further includes: if the i-th transmission resource among the M transmission resources overlaps in the time domain with one or more downlink reception windows, the first communication device cancels the transmission of data packets on the i-th transmission resource; or, the first communication device selects M transmission resources from N transmission resources, the M transmission resources not overlapping in the time domain with the downlink reception windows.
