ERROR CORRECTION FOR DATA PACKETS IN SHORT-RANGE WIRELESS COMMUNICATIONS SYSTEMS

A first device may establish, with a second device, a logical link associated with short-range communications. The first device may receive a first packet carried on the logical link. When the first PDU data fails the decoding check, the first device may determine, based on the logical link, a first operational mode from a plurality of operational modes for error correction, the first device may receive a set of retransmission packets on the logical link, each of the set of retransmission packets including respective PDU data that is a retransmission of the first PDU data, and the first device may apply, based on the first PDU data included in the first packet and the respective PDU data included in each of the set of retransmission packets, the first operational mode for error correction. 第一设备可以与第二设备建立与短距通信相关联的逻辑链路。第一设备可以接收逻辑链路上承载的第一分组。当第一PDU数据未通过解码校验时，第一设备可以基于逻辑链路而从用于错误纠正的多个操作模式确定第一操作模式，第一设备可以在逻辑链路上接收重发分组集合，重发分组集合中的每个重发分组包括作为第一PDU数据的重发的相应PDU数据，并且第一设备可以基于被包括在第一分组中的第一PDU数据和被包括在重发分组集合中的每个重发分组中的相应PDU数据来应用用于错误纠正
