Format-optimized MAC (Media Access Control) packet determination method and system

Abstract

The invention discloses a format-optimized MAC (Media Access Control) packet determination method which is implemented in a way that: determining an ACMAC (Access Channel Media Access Control) packaging format which can be supported by the terminal and network between the terminal side and the network side, wherein the ACMAC packaging format comprises variable-length ACMAC packaging format. The invention also discloses a format-optimized MAC (Media Access Control) packet determination system which comprises a determination unit for determining the ACMAC packaging format which can be supported by the terminal and network, wherein the ACMAC packaging format comprises variable-length ACMAC packaging format. By using the method and system disclosed by the invention, data can be transmitted after optimizing the packaging of the ACMAC so as to support the scene of low-rate transmission.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a method and system for determining a MAC packet with an optimized format in an access channel. Background technique [0002] In a code division multiple access (CDMA) wireless communication system, the data transmitted through the air link needs to be encapsulated by the protocol stack, that is, when the data passes through the layers of the sender's protocol stack, the header and tail corresponding to the protocol layer need to be added. When data passes through each layer of the receiver's protocol stack, the header and tail corresponding to the protocol layer need to be removed, so as to standardize and simplify the data transmission process. However, this encapsulation method also brings a problem. Due to layer-by-layer encapsulation, a large amount of resources are used to transmit these encapsulated format information, that is, overhead information, which reduces the resour...

Problems solved by technology

[0011] It can be seen from the above table 3 that the head / tail information of the existing MAC encapsulation is designed based on the existing higher data rate, which can guarantee the transmission at a higher access channel rate, but cannot guarantee low The transmission at high speed is mainly due to the fact that the overhead information encapsulated by the existing ACMAC is too large, which makes it impossible to transmit at all or the transmission efficiency is very low in the case of low speed. Therefore, the new requirement is: in order to support low-speed transmission scenarios, The encapsulation of ACMAC must be optimized before data transmission

However, no effective solution exists for this new requirement
