Abstract

The invention relates to a method for constructing a protocol data unit (PDU) of a media access layer (MAC layer) of a wireless communication system. The method comprises the following steps: constructing an MAC PDU in different sections, wherein one MAC Sub-PDU comprises four parts, that is, a synchronous code of N bit, an MAC head, an MAC Payload and a cyclic redundancy check code (CRC) of K bit. The invention further relates to an SDU (Service Data Unit) on the MAC layer and control information unit recovery method. By adopting the method, the throughput rate of the system is increased, and the precious shortage resource is saved.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to a method for constructing a protocol data unit (PDU) of a medium access layer (MAC layer) in a wireless communication system, a MAC layer service data unit (SDU) and a MAC layer control information unit after demultiplexing at a receiving end (Control Element) recovery method. Background technique

[0002] Due to the particularity of the propagation environment, the physical layer of the wireless communication system often generates bit errors during transmission. And because of the existence of bit errors, it will lead to the spread of errors, which greatly reduces the system throughput and wastes precious air interface resources. Taking the LTE system as an example, the construction method of the MAC layer PDU is as follows: figure 1 As shown, each sub-header in the MAC header corresponds to a MAC Control element, MAC SDU or padding in the MAC payload in turn.
