Technical field

The invention belongs to wireless communication field, relate in particular to a kind of wireless communications method, 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 GSM derive and come towards Femto technology of indoor application or the like.

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 CollisionAvoidance) mechanism, system effectiveness is lower, and is bigger 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); Between the perhaps different STA, can compete wireless channel simultaneously through the right to use of CSMA/CA mechanism competition Radio Resource; Just bump this moment, causes waste of radio resources.For fear of collision, have CSMA/CA mechanism and require AP or STA when the competition wireless channel, to need random back, when all AP and STA keep out of the way,, be not used though wireless channel has the free time, this also is 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; (for example: FTP Download) achievable rate is not higher than 30Mbps (under the small data packets business but the TCP layer is under big packet downloading service; Because the expense ratio increases, but peaking speed is lower).Though 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 GSM 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 advantages of small volume (approximate with Wi-Fi) is disposed flexibly.Owing to coming from GSM evolution, all characteristics of GSM have almost been inherited in the Femto base station.Femto equipment just combines its limited coverage, and less access user waits the application scenarios characteristic, the device processes ability is reduced, and then reduce equipment cost.Consider that from duplex mode identical with GSM, the Femto base station can be divided into FDD and two types of duplex mechanism of TDD.FDD up-downgoing carrier resource symmetry, and the asymmetrical service feature of data service up-downgoing data traffic makes the FDD system have certain wasting of resources when facing data service.TDD system uplink downlink is operated on the same carrier wave, is that uplink downlink distributes different Radio Resources through 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 GSM (comprising the 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; M2M (machine-to-machine) etc. are difficult to realize the dynamic adaptation of business demand and resource division.Compare with Wi-Fi,, do not exist between base station or AP and terminal or the terminal owing to the waste of radio resources that competition conflicts and random back causes, so link efficiency is higher owing to Femto has adopted the centralized control mechanism based on scheduling.

Though the Femto system is also through being scheduling to uplink and downlink communication; Be the different terminal distributing radio resource; But the frame structure of its static configuration can not be up-downgoing flexible allocation Radio Resource, can not change with smaller particles degree self-adapted service, when professional with resource distribution when unbalance or can cause queuing when long; User experience reduces, and perhaps can cause the channel capacity waste.

System dynamics configuration communication frame among the present invention, thus realization specifically realizes through following method neatly to the up-downgoing scheduling of resource of each terminal equipment:

Step s1101: the network equipment obtains schedule information.

Wherein, schedule information comprises the dispatching requirement (for example: the service quality QoS demand of business to be scheduled and queue length, different business, service priority or the like) of the different business stream of each terminal equipment or each terminal equipment.

Wherein, Step s1101 also possibly comprise: (can the network equipment obtain the state information of descending transmission channel or the ability that quality information depends on terminal equipment to obtain state information or the quality information of transmission channel of the network equipment to each terminal equipment; If terminal equipment does not support that the network equipment can not rely on this channel information scheduling).

In the descending scheduling transmission, the frame period is confirmed to be accomplished by the scheduler of network equipment side.Scheduler is from the MAC or the high-rise down dispatch information that obtains of the network equipment.

Step s1102: the scheduler of the network equipment is accomplished dispatching algorithm, according to down dispatch information, or according to the state or the quality information of schedule information and channel, is all or part of terminal equipment scheduling transmission resources that business demand is arranged.

Each terminal equipment can pass through the time-division, and frequency division, sign indicating number divide, sky divides or transfer resource is shared in the combination of above-mentioned multiplex mode.

Step s1103: the network equipment calculates dispatching cycle in this frame according to the transfer resource of dispatching in this frame, confirms the structure of this frame;

The structure of confirming this frame also possibly comprise step afterwards: the frame length that calculates this frame.

Step s1104: the structure of this frame of network equipment broadcasting, and send the descending scheduling signaling.

Wherein, can pass through system information channel, perhaps system information channel combines with control channel, perhaps the structure of other these frames of channel radio;

Can send the descending scheduling signaling through control channel or other channels.

Wherein, step s1104 also possibly comprise step: the frame length of broadcasting this frame.

At this moment, through system information channel, perhaps system information channel combines with control channel, perhaps structure of other these frames of channel radio and/or frame length.

Through said process, realized dynamic-configuration to frame structure.

Receive the descending scheduling signaling of network equipment transmission when terminal equipment after; Check system information channel and control channel; According to system information and descending scheduling signaling; Calculate to obtain the transfer resource that each terminal equipment takies, confirm downlink transfer cycle, uplink transmission cycle and calculate the frame length of this frame;

If step s1104 not only broadcasts the structure of this frame and also broadcasted frame length, then terminal equipment directly obtains the frame length of this frame, does not need to calculate.

Come the detailed description system how through the dynamic-configuration frame structure through specifically describing an embodiment 12 below, thereby realize neatly up-downgoing scheduling of resource each terminal equipment.
