AI Technical Summary

Problems solved by technology

For communication device #1, because the LCID #α is a reserved value or an invalid value, an error occurs when parsing the sub-PDU carrying LCID #α, which in turn causes communication device #1 to be unable to determine how to process the entire MAC PDU

Abstract

The present application provides a method and device for processing a media access control protocol data unit, the method includes: obtaining a media access control MAC protocol data unit PDU, the MAC PDU includes N sub-PDUs, each sub-PDU includes a logical channel identifier LCID, the The N sub-PDUs are arranged according to the first order, and N is a positive integer; according to the first order, the parsing process for the N sub-PDUs is performed, and when the first sub-PDU is parsed, the parsing process is stopped, and the parsing is retained. The second sub-PDU, wherein the second sub-PDU includes at least one sub-PDU that is located before the first sub-PDU in the first order among the N sub-PDUs, and the value of the LCID included in the first sub-PDU is specified The reserved value can thus provide a processing method for the MAC PDU when the value of the LCID is an invalid value or a reserved value.

Description

technical field [0001] The present application relates to the field of communications, and, more particularly, to methods of processing media access control protocol data units. Background technique [0002] At present, there is known a technology for processing a Media Access Control (Media Access Control, MAC) Protocol Data Unit (Protocol Data Unit, PDU). In this technology, the MAC PDU is composed of multiple sub-PDUs, and each sub-PDU carries For logical channel identification (Logical Channel Identify, LCID), the communication protocol specifies a variety of LCID-corresponding processing methods, so that each sub-PDU can be analyzed based on the LCID carried in each sub-PDU. [0003] With the development of communication technology, the version of the communication protocol changes gradually, and the processing method of LCID stipulated by different versions of the communication protocol may change. Note that the processing method of LCID#α is not defined in the commun...
