101, described processor obtains the quality wireless channel indicated value for reflecting the wireless channel between AP and mobile terminal.
102, described processor is according to the wireless channel indicated value got, and changes the phase-shift phase of described phase shifter, points to target device to make the principal stresses angle of the compound direction figure of described each antenna.
Particularly, the device of described adjustment antenna pattern can be arranged on use MIMO technology AP and/or mobile terminal on; Wherein, described AP can be such as the network equipment that WLAN gateway, WIFI hot spot etc. support WLAN agreement; Described mobile terminal supports WLAN agreement.Wherein, described target device is described AP or described mobile terminal: if described device is arranged on described AP, then described target device is described mobile terminal; If described device is arranged on the mobile terminal, then described target device is described AP; Optionally, if described mobile terminal and described AP are provided with described device simultaneously, then Handshake Protocol can be set between described AP and described mobile terminal, according to network and user's request, side (described AP side or described mobile terminal side is only opened at synchronization, to open described AP side) the function of compound direction figure of adjustment multiple antennas, and the side (described mobile terminal side or described AP side are described mobile terminal side herein) of not opening adjustment function is target device.Described wireless channel indicated value, for reflecting the quality of the wireless channel between described AP and described mobile terminal, such as, can be reference signal strength instruction (Received Signal Strength Indication is called for short RSSI) or throughput (Throughput).In said device for each antenna in mimo system is configured with and each self-corresponding phase shifter; Described processor obtains the wireless channel indicated value of receive channel, and according to the described wireless channel indicated value got, change the phase-shift phase of described phase shifter, thus regulate the directional diagram (Antenna pattern) of described each antenna, make the principal stresses angle of the compound direction figure of described each antenna point to target device.
The method of the adjustment antenna pattern that the embodiment of the present invention provides, by being respectively each antenna configuration phase shifter corresponding with each antenna, and according to the wireless channel indicated value got, change the phase-shift phase of described phase shifter, thus regulate the directional diagram of each antenna, to make the principal stresses angle of the compound direction figure of described each antenna point to target device, achieve the change of the relative position according to mobile terminal and AP, the compound direction figure of dynamic conditioning multiple antennas, improves the throughput of system.
On the basis of above-described embodiment, change the mode of the phase-shift phase of described phase shifter, as long as the phase-shift phase that changes described phase shifter can be reached through thus make the principal stresses angle of the compound direction figure of described each antenna point to the mode of target device, can be such as, according to the rule pre-set only change a phase shifter phase-shift phase or, change one by one each phase shifter phase-shift phase or, change the phase-shift phase of multiple phase shifter, but the embodiment of the present invention is not once limited simultaneously.

If RSSI1 is greater than RSSI0, illustrate that the direction of sensing to target device of the principal stresses angle of the compound direction figure of described each antenna is close, therefore, the phase-shift phase continuing to increase phase shifter is f1+ ▽ f, (the concrete value of f1 and ▽ f can be arranged according to actual needs, ▽ f is the adjustment step-length of phase-shift phase) and the RSSI value after adjusting is obtained after the phase-shift phase of each adjustment phase shifter, the phase-shift phase determining how to adjust phase shifter is made comparisons with the previous RSSI value got, until when this wireless channel indicated value got is not more than the previous wireless channel indicated value got, illustrate that the principal stresses angle of the compound direction figure of described each antenna points to target device, therefore the phase-shift phase after adjustment previous for phase shifter is fixed up.Therefore, the method for the adjustment antenna pattern that the embodiment of the present invention provides can make described target device be in the signal cover of the principal stresses angle of the compound direction figure of described each antenna, thus the throughput of maximum target device to greatest extent.
If RSSI1 is less than RSSI0, illustrate that the sensing of the principal stresses angle of the compound direction figure of described each antenna deviate from the direction of target device, therefore, the phase-shift phase reducing phase shifter is-f1, and the RSSI value RSSI2 of the phase-shift phase obtaining phase shifter when being-f1, if RSSI2 is less than RSSI1, the phase-shift phase then continuing to reduce phase shifter is-f1-▽ f, and the RSSI value obtain adjustment after the phase-shift phase of each adjustment phase shifter after, the phase-shift phase determining how to adjust phase shifter is made comparisons with the previous RSSI value got, until when this wireless channel indicated value got is not less than the previous wireless channel indicated value got, illustrate that the principal stresses angle of the compound direction figure of described each antenna points to target device, therefore the phase-shift phase after adjustment previous for phase shifter is fixed up.
On the basis of above-described embodiment, the trigger condition of the phase-shift phase of adjustment phase shifter can be limited further by the threshold value preset, avoid the phase-shift phase frequently adjusting phase shifter, that is: if described processor determines that the difference of the initial value of this wireless channel indicated value got and described wireless channel indicated value is greater than first threshold, then the phase-shift phase of described phase shifter is progressively increased until the difference of this wireless channel indicated value got and the previous wireless channel indicated value got is not more than described first threshold.If described processor determines that the difference of the initial value of this wireless channel indicated value got and described wireless channel indicated value is less than Second Threshold, then progressively reduce the phase-shift phase of described phase shifter until the difference of this wireless channel indicated value got and the previous wireless channel indicated value got is not less than described Second Threshold.Wherein, first threshold and/or Second Threshold can be positive number or negative, both absolute value can equal also can be different, can determine according to the factor such as network condition and user's actual need in reality.
