First embodiment
In order to solve dual-antenna terminal in the prior art because user's grip etc. easily causes communication of mobile terminal matter
Amount declines, and the problem of influenceing power consumption of terminal and Consumer's Experience, the present embodiment proposes a kind of multi-antenna terminal, the present embodiment pair
The quantity for the antenna with base station communication is added in multi-antenna terminal, and existing circuit is improved, is increased
Antenna gating circuit, the antenna gating circuit can select two groups between antenna and radio circuit from multigroup antenna
Antenna as primary antenna and auxiliary antenna, and by primary antenna and auxiliary antenna respectively with the main transmitting-receiving path of radio circuit and auxiliary reception
Path connects.The setting up of the antenna gating circuit of the present embodiment allows the multi-antenna terminal of the present embodiment in multiple antennas
Any selection and switching primary antenna and auxiliary antenna, and terminal antenna quantity increases the selection face for increasing major-minor antenna, relatively
In the dual-antenna terminal that can only switch major-minor antenna in two antennas in the prior art, the day of the multi-antenna terminal of the present embodiment
Line options face is wider, can more tackle because user grip etc. reason caused by antenna occlusion antenna transmitting-receiving hydraulic performance decline, influence eventually
The problems such as holding power consumption.
The hardware configuration of the multi-antenna terminal of the present embodiment is illustrated with reference to Fig. 4.
As shown in figure 4, the multi-antenna terminal of the present embodiment includes at least three groups of antennas 411,412 ... 41M, antenna gating
Circuit 42, radio circuit 43 and BBP 44.
In the present embodiment, antenna gating circuit 42 includes the gating sub-circuit for selecting 1 switch selection circuit to form by multiple N
421 and one 2 select 2 switch selection circuits 422.Each N selects 1 switch selection circuit to have 2 first interfaces and one
Individual second interface, any one in 2 first interfaces can be connected with second interface.Gating sub-circuit 421 externally shows
With with X (X is not less than antenna sets number) individual first interface and two second interfaces, it is possible to achieve it is any in X first interface
Two first interfaces and second interface connect one to one.
The radio circuit 43 of the present embodiment is including main transmitting-receiving path 431 and 432 (TX and PRX in Fig. 4) all the way (same
At the individual moment, 431 only have a path to connect with 432) and auxiliary receiving path 433 (DRX in Fig. 4) all the way；Described 2 select 2 to open
Close in selection circuit A sides (shown in Fig. 4) two interfaces, interface and the main transmitting-receiving communication, another with it is described auxiliary
Receiving path connects；The gating sub-circuit 421 includes X first interface and two second interfaces, and described 2 select 2 switches to select
Circuit 422 each one second interface of orifice, each antenna in the interface of B sides two connect with least one first interface,
So that each antenna, which can pass sequentially through the N, selects 1 switch selection circuit, it can access described 2 and select 2 switch selection circuit B sides
At least one interface in two interfaces；The BBP 44 selects 2 switches selection electricity with the gating sub-circuit 421 and 2
Road 422 connects, and for obtaining switching command, controls the gating sub-circuit and 2 to select 2 switches selection electricity by the switching command
Road is by the target primary antenna selected from the antenna and the main transmitting-receiving communication, and will be selected from the antenna
The auxiliary antenna of target connects with the auxiliary receiving path.
The antenna gating circuit 42 of the present embodiment is to realize that X selects 2 by more devices, and the group number of antenna can be 3 tunnels, 4 tunnels, 5
Road etc., the present embodiment are not limited this.More in view of antenna amount, antenna gating circuit 42 is more complicated, the present embodiment
The antenna amount of multi-antenna terminal be preferably 3 groups.The position and the group number and terminal of antenna that the antenna of the present embodiment is set
Shape it is related.The present embodiment illustrates how 3 antennas are set by taking Conventional mobile terminals as an example, when antenna sets number is 3 groups,
At least just like three kinds of set-up modes shown in Fig. 5 (a) (b) (c).As shown in Fig. 5 (a), three groups of antennas 411,412 and 413 are distinguished
It is arranged on top, bottom left and the bottom right of multi-antenna terminal；As shown in Fig. 5 (b), three groups of antennas 411,412
With 413 tops, middle part and bottom for being separately positioned on multi-antenna terminal；As shown in Fig. 5 (c), three groups of antennas 411,412 and 413
It is separately positioned on the top left side, top right side and bottom of multi-antenna terminal.Triantennary can be arranged on terminal in the present embodiment
Different surfaces on, every group of antenna may be located on position, the present embodiment such as front or the back side or the side of terminal not to be had to this
There is restriction.When multi-antenna terminal the antenna group number be 3, as shown in fig. 6, it is described gating sub-circuit 421 include two 2 choosing
1 switch selection circuit 4211,4212, described 2 selects 1 switch selection circuit to include two first interfaces and 1 second interface, Mei Gexuan
The second interface of logical sub-circuit and described 2 select 2 switch selection circuits 422 B sides an orifice；One group in three groups of antennas
Antenna is respectively communicated with two 2 first interfaces for selecting 1 switch selection circuit, remaining antenna and remaining first interface one simultaneously
One corresponding connection.It should be appreciated that in the present embodiment, above-mentioned two 2 selects 1 switch selection circuit to form 3 gatings for selecting 2

The working parameters of antenna or auxiliary antenna are compared with corresponding predetermined threshold value, if the workability of primary antenna or auxiliary antenna
Energy parameter is less than corresponding predetermined threshold value, then judges to meet antenna switching condition.Wherein, it is contemplated that the transmitting-receiving performance to primary antenna
Requirement it is typically higher than auxiliary antenna, predetermined threshold value corresponding to primary antenna or auxiliary antenna could be arranged to different values.Additionally, it is contemplated that
If in some an extreme time of antenna receive and dispatch performance drastically deteriorate, even if some when this group of antenna antenna performance
Parameter is not below corresponding predetermined threshold value, is also very likely dropped in very short time afterwards under predetermined threshold value, so this
BBP can also regularly continuously acquire the antenna performance parameters of the major-minor two-way antenna to work in embodiment；
For example, for each work antenna, the working parameters of work antenna are continuously obtained according to default time interval,
Judge whether the master of current work or the working parameters of auxiliary antenna deteriorate in preset time period, and calculate deterioration amount
Size, compare the size of the deterioration amount and default change threshold, if deterioration amount is less than default change threshold, judgement is unsatisfactory for
Antenna switching condition, if deterioration amount is more than or equal to predetermined threshold value, judgement meets antenna switching condition.Wherein, when default
Between interval advantageously smaller than equal to preset time period size so as to meeting that the judgement of antenna switching condition is more accurate
