Radio link protocols for enhancing efficiency of multi-link communication systems

摘要

Embodiments disclosed herein relate to a new set of radio link protocols (RLPs) configured to provide for efficient data transmission in a multi-link communication system. In an embodiment, an upper-layer packet is segmented into link-layer packets to be transmitted over a plurality of communication links, each including a first sequence number in accordance with a predetermined order. A second sequence number is further added to each link-layer packet to be transmitted for the first time. The second sequence number is configured to be in a sequence space associated with a particular communication link, and may be used for detection of missing packets.

1. A method for data processing in a multi-link communication system, comprising:
receiving link-layer packets corresponding to an upper-layer packet through different communication links, wherein each link-layer packet comprises a plurality of sequence numbers; receiving a flush message from a sender, the flush message indicating an end of a burst of data and including a last link-layer packet transmitted; determining, upon reception of the flush message, whether there is a gap in one of the plurality of sequence numbers of the received link-layer packets that has not been reported previously; and sending a message to the sender, if at least one gap in one of the plurality of sequence numbers of the received link-layer packets is detected.
