Problems solved by technology

[0002] If an end-device includes two or more uplink grants with overlapping time resources, the end-device may have some already generated MAC Protocol Data Units (PDUs) that end up being de-prioritized and thus not fully sent
Also, in Unlicensed New Radio (NR-U) a similar situation can arise where the generated PDU cannot be sent due to a listen before talk (LBT) failure

Abstract

The embodiment of the invention relates to equipment, a method, a device and a computer readable storage medium for resource selection of transmission of pending data units. The method includes determining a set of allowed HARQ processes for transmitting a data unit based on at least one condition if it is determined that the data unit is not successfully transmitted using a resource associated with an original HARQ process; a further resource associated with the target HARQ process is selected from the set of allowed HARQ processes, and the data unit is transmitted to the second device using the further resource. In this manner, a scheme for conditional HARQ handover is proposed so that the pending MAC PDU can be retransmitted quickly. Meanwhile, retransmission of the pending MAC PDU does not affect other scheduling services.

Description

technical field [0001] Embodiments of the present disclosure relate generally to the field of telecommunications, and in particular to an apparatus, method, apparatus, and computer-readable storage medium for resource selection for transmission of pending data units. Background technique [0002] If the end device includes two or more uplink grants with overlapping time resources, the end device may have some MAC Protocol Data Units (PDUs) that have been generated, which are eventually de-prioritized and thus not fully transmitted . Also, in Unlicensed New Radio (NR-U), a similar situation may arise where the generated PDU cannot be sent due to a listen-before-talk (LBT) failure. [0003] A "generated but not sent" MAC PDU may be considered a pending MAC PDU. For dynamically granted de-prioritized PUSCH, such MAC PDUs may be stored in the HARQ buffer and may allow the network device to schedule retransmission resources associated with the same HARQ process, ie, with the or...
