Abstract

The invention discloses a method for transmitting an RLC layer status report control PDU, comprising: a user equipment receives configuration information sent by a network device, the configuration information includes at least one control PDU format; the user equipment selects the at least one One of the control PDU formats generates a status report control PDU, and reports the status report control PDU. The embodiment of the invention also provides related equipment. The format of the status report control PDU reported by the user equipment in the embodiment of the present invention can be diversified, and in some cases, the requirements of diverse scenarios can be met.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for transmitting an RLC layer state report control PDU and related equipment. Background technique [0002] In the existing radio link control (Radio Link Control, RLC) retransmission feedback mechanism, when the RLC transmits a protocol data unit (Protocol Data Unit, PDU), it will configure a sequence number (sequence number) for each PDU, and send The end sends PDUs according to the configured sequence numbers. Subsequently, the receiving end feeds back the PDU receiving status of the receiving end to the sending end through a PDU status report (status reportPDU). The sender decides which PDUs to retransmit based on the PDU status report. [0003] According to the LTE RLC protocol, the status report PDU fed back by the receiving end includes the maximum sequence number of the PDU currently successfully received by the receiving end, and the sequence number of ...
