Signal simulation method and device for wireless connection aggregation MAC layer protocol data unit

Abstract

The invention belongs to the technical field of wireless communication testing, and provides a signal simulation method and device for a wireless connection aggregation MAC layer protocol data unit. The method comprises the following steps: simulating communication data transmitted by a plurality of user terminals at the same time; simulating a process of simultaneously performing data interaction on communication data transmitted by a plurality of user terminals on corresponding user terminal-communication terminal channels based on an aggregated MAC layer protocol data unit; the generation process of the aggregated MAC layer protocol data unit comprises the following steps of: clustering parameters generated by the aggregated MAC layer protocol data unit in a multi-user scene into three types of parameters according to parameter attributes; the first type of parameters are user configuration types, the second type of parameters are aggregation MAC layer protocol data setting types, and the third type of parameters are MAC head setting types; correspondingly integrating the first type of parameters and the second type of parameters into a first list and a second list respectively; the second type parameter setting item is configured as an attribute column of the first list; and the third type parameter setting item is configured as an attribute column of the second list.

Description

technical field [0001] The invention belongs to the technical field of wireless communication testing, and in particular relates to a signal simulation method and device for aggregating MAC layer protocol data units in a wireless connection. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the rapid growth of the number of handheld electronic devices and the continuous development of wireless network services, people increasingly expect wireless local area networks to have higher rates. In order to improve the throughput of the MAC layer, the IEEE 802.11n standard proposes an aggregated MAC layer protocol data unit (A-MPDU), which has been used until now, and the latest WIFI standard also adopts this technology. A-MPDU aggregates the MAC layer protocol data units (MPDUs) encapsulated by 802.11 packets. By sending several MPDUs at a ti...

Problems solved by technology

[0004] The inventors found that the signal simulation efficiency of the wireless connection aggregation MAC layer protocol data unit is low at present, and the main reason is that the data processing logic based on the protocol standard is not fully considered in the generation process of the wireless connection aggregation MAC layer protocol data unit. The relationship between different types of parameters in the setting item list is relatively scattered and confusing, and the operation process is more cumbersome, and the process of generating A-MPDU data takes more time, thereby reducing the signal simulation efficiency of the wireless connection aggregation MAC layer protocol data unit
