DATA TRANSMISSION CONTROL METHOD AND SYSTEM IN BEIDOU COMMUNICATION SYSTEM, AND RELATED APPARATUS

Document Type and Number:

WIPO Patent Application WO/2023/011329

Kind Code:

A1

Abstract:

A data transmission control method and system in a Beidou communication system, and a related apparatus. In the method, a terminal can split, in an MDCP layer, one MDCP SDU into one or more pieces of MDCP segment data of a fixed length, and add a next indication field to a header of each piece of MDCP segment data to obtain an MDCP PDU, and the next indication field may be used for indicating that the current MDCP PDU is a starting frame or an intermediate frame or a last frame in continuously sent frames, or a frame that is sent separately. The terminal can send one or more MDCP PDUs to a Beidou network device. The Beidou network device can combine a plurality of MDCP PDUs into one MDCP SDU according to the next indication fields in the MDCP PDUs. By implementing the method, even under a constraint that the Beidou communication system and the rate are limited, the terminal can still reliably transmit data to the Beidou network device.
