Description
Technical field
The method and network transmitted the present invention relates to information in mobile communication technology field more particularly to TDMA system are set
Standby, user equipment.
Background technology
TDMA (Time based on WLAN (Wireless Local Area Networks, Wireless LAN)
Division multiple access, time division multiple acess) system is a kind of novel networking mode, it uses the physics of WLAN
The upper layer techniques of layer technology and TDMA, the two are rightly merged, to meet the application of special scenes.
In the TDMA system based on WLAN, user's time-derived channel resource, each user occupancy transmission data for a period of time.
The system uses WLAN physical layer mechanisms, between base station and user when transmission data, is needed before each frame data there are one leading sequence
Row, the sequence occupy a bit of time, when user has multiple frames to need to send, time that targeting sequencing occupies with transmission frame
Number and be multiplied.Techniques of frame aggregation is introduced in wlan system, polymerize multiple data frames to reduce targeting sequencing occupancy
Time.Meanwhile in data transmit-receive, need to reply ACK/NACK confirmation messages by BA control frames, when between user and base station
When persistently there is data transmit-receive, accordingly BA control frames also need frequently to send, for the limited channel distributed to user in system
More valid data are transmitted in holding time, are sent simultaneously by the way of BA, BAR control frame and data frame aggregation in WLAN
Information and date information is controlled, and reduces the time of targeting sequencing occupancy.TDMA system based on WLAN inherits techniques of frame aggregation,
Support data frame polymerize transmission with data frame, to save targeting sequencing time when data are sent, has the more time for having
Imitate data transmission.
Link circuit self-adapting is an important component in wireless resource management, the TDMA system based on WLAN without
It is also occupied an important position in line Resource Management Algorithm.AMC (Adaptive Modulation and Coding, Adaptive Modulation
Coding) it is a kind of important link adaptation techniques, the MCS (Modulation of link can be adaptively adjusted using AMC algorithms
And Coding Scheme, modulating-coding strategy), the variation of link is tracked, ensures the quality of data transmission.
In traditional wlan system, it is adaptive selected what user used using the Measurement and Data Processing of WLAN physical layers
MCS.In the TDMA system based on WLAN, base station can also be measured using WLAN physical layers, obtain measurement data and evidence
This adjustment MCS.But in control frame and when data frame aggregation, the measurements of WLAN physical layers cannot be distinguished data type, it is unified into
Row measures and feedback, the MCS obtained using these metrical informations can not be well adapted for the performance requirement of control frame, and
