Technical field

The invention belongs to wireless communication field, relate in particular to wireless communication system and equipment.

Background technology

In recent years, the wireless communication system that is applied to short-and-medium communication distance have wireless local area network technology WiFi based on 802.11 standards, bluetooth (Bluetooth) system based on 802.15 and by mobile communication system derivative and come towards Femto technology of indoor application etc.

WiFi technology based on 802.11 is the current the widest a kind of wireless network transmission technology of using.Because the WiFi system has adopted carrier sense/conflict to avoid (CSMA/CA, Carrier Sense Multiple Access with Collision Avoidance) mechanism, system effectiveness is lower, and is larger to waste of radio resources.The basic reason that causes this problem is that CSMA/CA mechanism is a kind of random division multiple accessing access mechanism based on competition, access point (AP, Access Point) and website (STA, Station), perhaps between different STA, can by the right to use of CSMA/CA mechanism competition Radio Resource, compete simultaneously wireless channel, just bump this moment, causes the waste of Radio Resource.For fear of collision, have CSMA/CA mechanism and require AP or STA to need random back when the competition wireless channel, when all AP and STA keep out of the way, though wireless channel is available free, be not used, this is also the significant wastage to wireless channel.For above-mentioned reasons, 802.11 system effectivenesies are lower.For example: 802.11g system physical layer peak rate can reach 54Mbps, but transmission control protocol (TCP, Transmission Control Protocol) layer under large packet downloading service achievable rate not higher than 30Mbps, under the small data packets business, because the expense ratio increases, but peaking speed is lower.Although there is above-mentioned shortcoming, 802.11 systems are flexible, do not rely on centralized control mechanism, therefore also can realize lower equipment cost.

Femto technology based on the 3GPP standard is from mobile communication system evolution and the new technology that covers in a kind of faced chamber that comes.Based on the data statistics to the 3G system, about 70% data service all occurs in indoor, so indoor high-speed rate data access scheme is just particularly important.The Femto base station is called femto base station, and volume small and exquisite (approximate with Wi-Fi) is disposed flexibly.Owing to coming from mobile communication system evolution, Femto has almost inherited the base station all characteristics of mobile communication system.Femto equipment is just in conjunction with its limited coverage, and the less application scenarios features such as access user reduce the device processes ability, and then reduces equipment cost.Consider from duplex mode, identical with mobile communication system, the Femto base station can be divided into Frequency Division Duplexing (FDD) (FDD, Frenqucy Division Duplexing) and time division duplex (TDD, Time Division Duplexing) two classes duplex mechanism.FDD up-downgoing carrier resource is symmetrical, and there is certain wasting of resources when making the FDD system in the face of data service in the asymmetrical service feature of data service up-downgoing data traffic.TDD system uplink downlink is operated on same carrier wave, is that uplink downlink distributes different Radio Resources by the time division resource, therefore can the asymmetrical data service of better adaptive up-downgoing business demand than FDD.Yet, the TDD duplex mode of mobile communication system (comprise Femto system), up-downgoing resource static allocation, in the face of the different Various types of data business of demand, for example: browsing page, mobile video, moving game, machine is difficult to realize the dynamic adaptation of business demand and resource division to machine (M2M, machine-to-machine) etc.Compare with Wi-Fi, because Femto has adopted based on the centralized control mechanism of dispatching, between base station or AP and terminal, perhaps do not exist between terminal due to the waste of radio resources that competition conflicts and random back causes, so link efficiency is higher.

Although the Femto system is also by being scheduling to uplink and downlink communication, be different terminal distribution Radio Resources, but the frame structure of its static configuration can not mate the Radio Resource of up-downgoing flexible allocation, can not change with less granularity self adaptation business, when business and resource distribution when unbalance or can cause and queue up when long, the user experiences reduction, perhaps can cause the channel capacity waste.
