Embodiment
Below in conjunction with drawings and Examples, the embodiment of the application is described in further detail.Following examples for illustration of the application, but are not used for limiting the scope of the application.
Those skilled in the art understand, in the embodiment of the application, the size of the sequence number of following each step does not also mean that the priority of execution sequence, and the execution sequence of each step should be determined with its function and internal logic, and should not form any restriction to the implementation process of the embodiment of the present application.
In addition, terms such as " first ", " second " in the application, only for distinguishing different step, equipment or module etc., neither representing any particular technology implication, also not representing the inevitable logical order between them.
Fig. 1 is the flow chart reconfiguring the method for antenna described in the application's embodiment, and as shown in Figure 1, described method can comprise:
S120: the current transmission quality that can provide determining an equipment;
S140: the current transmission quality that can provide in response to described equipment is greater than the service quality QoS of at least one business, and the difference of the QoS of the described current transmission quality that can provide and described at least one business is greater than at least one margin threshold, reconfigures at least one antenna of described equipment.
The method reconfiguring antenna described in the embodiment of the present application, the transmission quality that can provide when an equipment is current be greater than the service quality (Quality of Service) of one or more business and the difference of the QoS of the described current transmission quality that can provide and described at least one business is greater than at least one margin threshold time, mean that the current antenna participating in communication has redundancy, can reconfigure the antenna of equipment.Thus avoid the waste of resource.
In the embodiment of the application, the above-mentioned current transmission quality that can provide can comprise the current transmission rate that can provide and/or current time delay.
Exemplary, in the embodiment of the application, transmission rate is also called bandwidth, be in the unit interval from certain network a bit to another point by " the maximum data rate ".Conventional unit is bps (bit per second), i.e. how many bits per second.Current time delay refers in the buffer queue being grouped in described equipment to be waited in line to send experienced time delay.
In an optional execution mode, if the current transmission quality that can provide is the current transmission rate that can provide, as shown in Figure 2, the current transmission quality that can provide of described equipment is provided in above-mentioned S120, can comprises:
S121: determine the first channel condition; Wherein, to be described equipment carry out by the antenna of current use and at least one Correspondent Node equipment the channel condition that communicates to described first channel condition;
S122: at least according to described first channel condition, determines the current transmission rate that can provide of described equipment.
Exemplary, above-mentioned first channel condition can carry out for described equipment the first channel matrix of communicating by the antenna of current use and at least one Correspondent Node equipment.Channel matrix describes the channel characteristics of the spatial channel allocation that M and N root antenna is formed between any two, and this channel characteristics can comprise amplitude, frequency and phase component feature etc.After determining channel matrix, just according to selected transmission mode, code encoding/decoding mode etc., the transmission rate that described equipment can provide in theory can be determined.If described equipment carries multiple business simultaneously, then the transmission rate that described equipment can provide in theory can be deducted by the transmission rate that other business take, the current transmission rate that can provide just can be provided.Such as, if described equipment can provide the transmission rate of 10M in theory, business 1 and business 2 occupy 5M, then the current transmission rate that can provide of described equipment only has 5M.
The selection of data-transmission mode, generally can determine according to the ability of channel condition and equipment, also can adjust.But, once determine transmission mode, then can according to the size of coded system determination transmission block of 3GPP standard definition and the size of bit rate of eating dishes without rice or wine.
The selection of code encoding/decoding mode is then more flexible.In systems in practice, therefore the ability supported according to mobile phone, the power consumption, transmission power capabilities etc. of mobile phone, can select different channel coding/decoding modes neatly, and the actual like this message transmission rate that can realize also follows selected coded system difference and different.Such as, enter to have more (Multiple In Multiple Out in open loop more, MIMO) in system, when transmitting terminal does not obtain the channel feedback information of receiving terminal, on each parallel channel, data flow can be distributed power equably and be taked identical code encoding/decoding mode, and its data are more general than closed-loop MIMO system little.
As shown in Figure 3, described equipment can be a mobile electronic device, and described Correspondent Node equipment can be a base station BS 1.Described mobile electronic device is configured with 8 antennas (A1, A2, A3, A4, A5, A6, A7, A8), and described base station BS 1 is configured with 2 antennas (a1, a2).If 8 of described mobile electronic device antennas are all for the reception of downstream signal, then the channel condition (second channel matrix) communicated between described mobile electronic device with described base station BS 1 is:
In actual applications, described equipment may only use a part of antenna to communicate with described base station BS 1, such as, supposes that current 3 antennas (A1, A2 and A5) that employ of described equipment communicate with described base station BS 1.Therefore, above-mentioned first channel matrix can be:
Can find out, above-mentioned first channel matrix is the subset of above-mentioned second channel matrix.In order to obtain above-mentioned first channel matrix, in the embodiment of the application, as shown in Figure 4, determine the current transmission quality that can provide of an equipment at above-mentioned S120 before, described method can also comprise:

Still for the scene shown in Fig. 3.In this scenario, described mobile electronic device can be made in advance to be communicated with base station BS 1 by its 8 antennas, then adopt following formula 1 to calculate second channel matrix:
Y=H*x+n ... formula 1
Wherein, y is the signal vector that described mobile electronic device receives, and H is second channel matrix, and x is the signal vector that base station BS 1 is launched, and n is noise vector.Mutual by advance, mobile electronic device just can know x, thus after measurement obtains y, just can determine H.

S123: determine that described equipment carries out the length of the current transmit queue communicated by the antenna of current use and at least one Correspondent Node equipment;
S124: at least according to the length of described current transmit queue, determines described current time delay.
The queuing delay of a specific cluster will depend on quantity that arrive in advance, that wait in line the grouping to link transmission.If this queue is empty, and currently do not have other to be grouped in transmission, then the queuing delay of this grouping is 0.On the other hand, if flow is very large, and other groupings many are also waiting to be transmitted, and this queuing delay will be very large.Under extreme case, when network occur congested cause packet loss time, this time delay just can be considered as infinity.

Similar, above-mentioned 3rd channel condition also can be characterized by the 3rd channel matrix.Described 3rd channel matrix also can be the subset of above-mentioned second channel matrix.
For scene shown in Fig. 3, if the antenna set determined is 2 antennas (A1, A2), then the 3rd channel matrix can be:
According to described 3rd channel matrix, just can predict, if described equipment is communicated with Correspondent Node by described antenna set, transmission rate will reach how many.
S142B: be greater than the bandwidth threshold specified in the QoS of described at least one business in response to described anticipated transmission speed, and the difference of the bandwidth threshold specified in the QoS of described anticipated transmission speed and described at least one business is not more than at least one speed margin threshold, described antenna set is reconfigured, makes described equipment by the data of the described at least one business of described antenna set transmission.
If the transmission rate estimated can meet the requirement of QoS, and the difference of the bandwidth threshold specified in the QoS of described anticipated transmission speed and described at least one business is not more than at least one speed margin threshold, just described antenna set is reconfigured, such as, change the operating frequency of described antenna set, make described equipment can by the data of described antenna set transport service.
