106 performances that access terminal may be subject to and from access terminal 106 Received signal strength and the impact of blocking that transmits.Such as, because an object (such as, hand or health) has blocked antenna, therefore equipment performance may seriously be affected.Under some scenes, this impact may cause call drop or paging failure.In addition, in some instances, block and may cause higher transmitting power, it may cause increasing the interference of communication network, and produces high power consumption.Therefore, the system, the apparatus and method that are used for selecting the antenna for Signal reception and/or transmission based on the various performance characteristicses of antenna are needed.This selection can depend on many factors, hereafter will describe these factors in detail.Depend on these factors, can be one or more for what improve that the mode of Signal reception/transmission select in antenna.
Fig. 4 is according to some embodiments, in figure 3 shown access terminal 106 the functional block diagram of a part.In some cases, access terminal and 106 can comprise two antenna 370a and 370b.This accesses terminal and can also comprise two radiating circuit 330a, 330b, two receiving circuit 340a, 340b, commutation circuit 360 and processor/controllers 320.Antenna 370a and 370b can be used by any one in radiating circuit and receiving circuit (it comprises radiating circuit 330a, 330b and receiving circuit 340a, 340b).In certain embodiments, radiating circuit 330a, 330b and receiving circuit 340a, 340b can send and receive the information be associated with specific wireless access technology separately.Such as, radiating circuit 330a and receiving circuit 340a may be used for sending and receiving only data communication, and radiating circuit 330b and receiving circuit 340b may be used for sending and receiving voice communication.
As described above, radiating circuit 330a, 330b and receiving circuit 340a, 340b can use multiple antenna 370a and 370b to carry out sending and receiving simultaneously.But, as described above, based on any one in many factors, an antenna (such as, antenna 370b) performance may with another antenna (such as, antenna 370b) to compare better, described many factors can relate to but be not limited to: the adjacency of the layout of the antenna on 106 that accesses terminal, exterior object and antenna 370a and 370b or intrinsic antenna performance.In addition, during operation, some radiating circuit can have different data transport priority or transmitting power selection.
The various factors affecting antenna performance can comprise some operating conditions, wherein these operating conditions cause the one or more sensitivity decrease (desense) in antenna 370a and 370b, or otherwise cause one or more performance characteristicses of antenna 370a and/or 370b to reduce.Such as, the hand of user may be held and access terminal 106, thus it is one or more in fact to block in antenna 370a and 370b.For another example, accessing terminal 106 may be placed with antenna 370a and/or 370b is operated with so not desirable reception and/or transmitting situation.These scenes may reduce the power level of Received signal strength, therefore make more to be difficult to receive and demodulate signal.These scenes also may make to be difficult to effectively transmit.Such as, may overall signal strength be reduced to one or more the blocking in antenna 370a and 370b, make radiating circuit 330a, 330b and 330n may need to increase power level.But for the transmitted power level increased, access terminal 106 radio frequency (RF) safety requirements of obeying supervision possibly, and may need to access terminal 106 before coming into the market, and operates under specific guideline.Such as, the equipment operated near human body is assessed, to determine the specific absorption rate (" SAR ") that their electromagnetic wave produces.SAR is the time speed of the electromagnetic energy absorption of per unit mass in lossy dielectric, and it can be expressed as:
SAR ( r ) = &sigma; ( r ) &rho; ( r ) | E ( r ) | rms 2 (formula 1) wherein, E (r) is the exogenous electric field at a r place, and σ (r) and ρ (r) is corresponding equivalent conductivity and mass density respectively.In one aspect, these safely instruction principles can limit the amount of the transmitted power level of permission.Therefore, when one or more in antenna 370a and 370b are blocked, the maximum transmit power level of permission can be reduced significantly to avoid exceeding SAR restriction.
Due to access terminal 106 operation may affect the performance of antenna 370a and/or 370b, therefore can expect the dynamical system and the method that have for receiving circuit 340a, 340b and radiating circuit 330a, 330b being coupled to antenna 370a and/or 370b, embodiment as described herein provides.Therefore, some aspect of each embodiment described herein is aimed at: switch radiating circuit 330a, 330b and receiving circuit 340a, 340b, to be undertaken sending and receiving by different antenna 370a and 370b, thus improve access terminal 106 performance.Such as, may expect that the receiving circuit 340b receiving limit priority communication is received by the antenna 370b compared with antenna 370a with more best performance characteristic.In addition, if receiving circuit 340b and/or radiating circuit 330b is coupled to peak performance antenna 370b, then other reception and/or radiating circuit power requirement can realize the performance of improvement.In one embodiment, the switching at runtime of radiating circuit and receiving circuit can alleviate hand/health and block, and can allow to select antenna by this way, to meet supervision restriction with the minimum cost of performance loss, and/or realize good transmitting and receiving situation.In addition, in one aspect, emitting antenna selecting can allow to alleviate interference, and minimum amount of transmission power can be used to provide target service quality.
