Wireless network medium access control system and channel parameter regulation method

Abstract

The invention discloses a wireless network media access control system and the channel parameter adjusting method of the system. The system comprises a base station and a terminal; the terminal comprises a measuring module used for measuring the downlink channel information and storing the channel information in the channel information table and a feedback module used for calculating the channel information statistical value, constructing the report message of the channel information and sending the feedback report message to the corresponding base station; the base station comprises a request module used for selecting a feedback mode, constructing the request message of the channel information and sending the request message to the terminal when the base station requests the terminal to send the current feedback channel information; the base station comprises a first adjustment module used for controlling the physical layer to adjust the downlink transmission power and a second adjustment module used for determining the power value needed to be adjusted of each terminal, storing the power adjusted value and the identification of the corresponding terminal in the uplink power adjustment table, counting the number of the terminals needed to be adjusted in power and adjusting the uplink transmission power of the corresponding terminal. The wireless network media access control system and the channel parameter adjusting method of the system make the wireless network media access control be well realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless network medium access control system and a channel parameter adjustment method thereof. Background technique [0002] Wireless Metropolitan Area Network (802.16 WirelessMAN) is a broadband network capable of providing high-speed wireless access within a metropolitan area (see Carl Eklund, Roger B. Marks, "IEEE Standard 802.16: A Technical Overview of the WirelessMANTM Air Interface for BroadbandWireless Access”, IEEE C802.16-02 / 05, 2002). The IEEE 802.16 working group released IEEE Std 802.16-2004 on October 1, 2004, which defines the air interface physical layer (PHY) and media access control layer (MAC) specifications of the wireless metropolitan area network broadband wireless access system. [0003] IEEE Std 802.16e was released in February 2006, which defines the air interface specifications for mobile broadband wireless access systems. [0004] H...

Problems solved by technology

[0004] However, the 802.16 protocol, that is, the wireless metropolitan area network protocol standard, only proposes several channel information feedback methods and general power control methods, and does not provide the specific implementation methods of the channel information feedback workflow and power control, making its Wireless network media access control is not well implemented
