Specific embodiment

When terminal device because position changes depart from the coverage of existing wave beam when, can by adjustment There is the width of wave beam to expand the coverage of existing wave beam, so as to realize that existing wave beam changes position Terminal device covering again.Consequently, it is possible to can then avoid because terminal device position changes again The DOA of computing terminal equipment.Just technical scheme provided in an embodiment of the present invention is described in detail below.

Fig. 1 is the schematic diagram according to the communication system 100 of one embodiment of the invention.As shown in figure 1, communication System 100 includes access device 102 and multiple terminal devices 104~108.Access device 102 can be example Such as, but not limited to, base station, terminal device 104~108 can be such as but not limited to mobile phone, panel computer, on The mobile devices such as network interface card, notebook computer.

Access device 102 constructs multiple downlink wave beams 110~114 using beamforming technique, so as to end End equipment 104~108 sends downstream signal.Specifically, access device 102 passes through wave beam 110 to terminal Equipment 104 sends downstream signal, downstream signal is sent to terminal device 106 by wave beam 112, by ripple Beam 114 sends downstream signal to terminal device 108.

It should be noted that it should be apparent to a person skilled in the art that during implementing, communication system 100 Comprising access device and the quantity of terminal device can be configured according to specific needs, its particular number is simultaneously It is non-to be only limitted to shown in Fig. 1.

Fig. 2 is according to the wave beam change schematic diagram of one embodiment of the invention.As shown in Fig. 2 access device 202 The wave beam 204 of terminal device (not shown) is pointed in generation one.Terminal device is in position A, at the A of position Within the coverage of wave beam 204.

Then, terminal device is moved to position B from position A, as shown in Fig. 2 position B is in wave beam 204 Coverage outside.

Terminal device leaves the coverage of wave beam 204, and terminal device can be caused to receive the letter of downstream signal Number quality, (Signal to Interference plus Noise Ratio plus make an uproar at signal and interference for example, SINR Acoustic ratio), decline to a great extent.When the signal quality that terminal device detects downstream signal is less than a predetermined threshold value When, it may be determined that beam angle adjusting parameter, and it is sent to access device 202.It can be appreciated that the default threshold Value can be used to assess whether terminal device is within the coverage of wave beam 204.Access device 202 is subsequent The width of wave beam 204 is redefined according to the beam angle adjusting parameter, so that terminal device is in width Within the coverage of the wave beam 204 spent after redefining.For ease of description, width is redefined it Wave beam 204 afterwards is labeled as wave beam 204 '.After as width is redefined shown in dotted-line ellipse in Fig. 2 Wave beam 204, i.e. wave beam 204 '.The location of terminal device B is within dotted-line ellipse, i.e. Terminal device in width redefine after the wave beam 204 i.e. coverage of wave beam 204 ' within.No Indigestibility, what terminal device also can be regular or lasting determines corresponding beam angle adjustment according to signal quality Parameter is simultaneously sent to access device 202, and without just determining that wave beam is wide only when signal quality is less than predetermined threshold value Degree adjusting parameter is simultaneously sent to access device 202.

Additionally, Fig. 2 also show the beam direction of wave beam 204.Within the coverage of wave beam 204, Closer to the position of beam direction, the signal quality of downstream signal is better.For example, comparing position A, position C closer to beam direction, therefore, signal quality at the C of position is better than position A.If consequently, it is possible to eventually End equipment is moved to position C from position A, and the signal quality of its downstream signal for being received can increase. If the signal quality that terminal device detects downstream signal increases, it is also possible to determine beam angle adjustment ginseng Number, and it is sent to access device 202.In this case, access device 202 can be adjusted according to beam angle Whole parameter reduces the width of wave beam 204.

The process just to beam angle adjustment is described in detail below.

Fig. 3 is the flow chart according to the beam angle method of adjustment 300 of one embodiment of the invention.Specific real During existing, beam angle method of adjustment 300 can be performed by being such as, but not limited to terminal device.

Step 302, beam angle adjusting parameter is determined according to received signal quality.

It can be appreciated that the signal from access device that is received by terminal device of above-mentioned received signal quality Quality.

Step 304, the beam angle adjusting parameter is sent to access device.

It should be apparent to a person skilled in the art that received signal quality can carry out table especially by down channel quality Levy.

During implementing, step 302 can be implemented as, the received signal quality be less than or When person is equal to predetermined threshold value, beam angle adjusting parameter is determined according to received signal quality.Implementing Cheng Zhong, above-mentioned predetermined threshold value can be configured according to specific needs.Additionally, the predetermined threshold value also can be by terminal Equipment and access device are consulted to determine.It can be appreciated that just determining when received signal quality is less than predetermined threshold value Beam angle adjusting parameter, it is possible to decrease beam angle adjusts frequency, so as to reduce terminal device and access device Processing load.It should be apparent to a person skilled in the art that received signal quality means less than predetermined threshold value User is removing the scope of wave cover.

During implementing, step 302 can be implemented as, the received signal quality be higher than or When person is equal to another predetermined threshold value, beam angle adjusting parameter is determined according to received signal quality.It can be appreciated that Received signal quality is improved, and explanation to a certain extent means that user moves towards beam center. In this case, the width of wave beam can be reduced by setting beam angle adjusting parameter.In beam angle quilt After diminution, the power of wave beam will be concentrated more, and wave cover is apart from farther.During implementing, Above-mentioned predetermined threshold value can be configured according to specific needs.Additionally, the predetermined threshold value also can by terminal device and Access device is consulted to determine.It can be appreciated that just determining that wave beam is wide when received signal quality is less than predetermined threshold value Degree adjusting parameter, it is possible to decrease beam angle adjusts frequency, so as to reduce the treatment of terminal device and access device Burden.It should be apparent to a person skilled in the art that received signal quality means to use higher than another predetermined threshold value Moved towards beam center at family.

On the other hand, step 302 can also be implemented as, regular or lasting according to received signal quality Determine beam angle adjusting parameter.The advantage of beam angle adjusting parameter is periodically determined according to received signal quality It is, it is possible to decrease determine the frequency of beam angle adjusting parameter, so as to reduce determination beam angle adjusting parameter The burden that this operation brings to terminal device.Lasting determines that beam angle is adjusted according to received signal quality The advantage of parameter is, when received signal quality changes, beam angle can be adjusted rapidly, Beam angle is adjusted much sooner.

During implementing, the beam angle adjusting parameter can expect the beam angle number of degrees, such as This one, step 302 can specifically, determine received signal quality it is corresponding expect the beam angle number of degrees.Example Such as, by received signal quality and the corresponding relation between the beam angle number of degrees can be expected, such as table 1 below, Expect the beam angle number of degrees to determine that received signal quality is corresponding.

Received signal quality	Expect the beam angle number of degrees

Table 1

Wherein, the corresponding expectation beam angle number of degrees of each received signal quality for being recorded in table 1 can be according to history Statistics, experimental result, simulation result or empirical results etc. are configured.

During implementing, beam angle adjusting parameter can also be the adjustment number of degrees, consequently, it is possible to walk Rapid 302 specifically include：

If for example, expecting that the beam angle number of degrees are 30 degree, the current beam width number of degrees are 25 degree, then adjust The number of degrees are 5 degree.

It can be appreciated that the current beam width number of degrees are the beam angle of the wave beam for currently pointing to terminal device The number of degrees, access device is exactly based on the wave beam and sends downstream signal to terminal device.

During implementing, beam angle adjusting parameter can also be degree offset amount, consequently, it is possible to Step 302 is specifically included：

During implementing, above-mentioned default adjusting step can be configured according to specific needs, for example should Default adjusting step could be arranged to 2 degree.Additionally, the default adjusting step also can be by terminal device and access Equipment consults to determine.

Because the width of wave beam can both expand, it is also possible to reduce, therefore the above-mentioned adjustment number of degrees and degree offset Amount both can be positive number, or negative.

During implementing, the beam angle adjusting parameter can also be expectation beam angle numbering, Consequently, it is possible to step 302 expects beam angle numbering specifically, determining that received signal quality is corresponding.Example Such as, by received signal quality and the corresponding relation between beam angle numbering can be expected, such as table 2 below, Expect beam angle numbering to determine that received signal quality is corresponding.

Table 2

During implementing, beam angle adjusting parameter can also be width numbering side-play amount, such one Come, step 302 is specifically included：

It should be apparent to a person skilled in the art that when received signal quality be related to expect beam angle numbering or During width numbering side-play amount, in the case of necessary, wave beam should be also stored in access device and/or terminal device Width is numbered and the corresponding relation between the beam angle number of degrees, so that access device is compiled according to expectation beam angle Number the corresponding beam angle number of degrees are searched, and the beam angle of terminal device is adjusted according to the beam angle number of degrees. Beam angle number and the beam angle number of degrees between corresponding relation can using such as but not limited to following table 3 come Realize：

Beam angle is numbered	The beam angle number of degrees

Table 3

It can be appreciated that the current beam width numbering is the beam angle of the wave beam for currently pointing to terminal device Numbering, access device is exactly based on the wave beam and sends downstream signal to terminal device.

It should be apparent to a person skilled in the art that record has some parameters related to wave beam in terminal device, Such as but not limited to the current beam width number of degrees and current beam width are numbered.It can be appreciated that in beam angle After adjusting successfully, terminal device needs to carry out above-mentioned parameter the modification of adaptability.For example, using expectation The beam angle number of degrees update the current beam width number of degrees.Again for example, being worked as using expecting that beam angle numbers to update Preceding beam angle numbering.Terminal device can be after the confirmation message from access device be received, to above-mentioned ginseng Number carries out the modification of adaptability, wherein, the confirmation message is used to indicate beam angle to adjust successfully.

During implementing, received signal quality can be divided into multiple different intervals, each is interval One beam angle of correspondence.Consequently, it is possible to determine that beam angle is adjusted according to received signal quality in step 302 Whole parameter, it should be appreciated that determine beam angle adjusting parameter according to interval belonging to received signal quality；Connect Receive signal quality and expect the corresponding relation between the beam angle number of degrees, it should be understood that received signal quality institute Category is interval and expects the corresponding relation between the beam angle number of degrees；Received signal quality is compiled with expectation beam angle Corresponding relation between number, it should be understood that interval belonging to received signal quality to number it with beam angle is expected Between corresponding relation.

In reality scene, terminal device is likely to be in high-speed mobile scene, it is also possible in low speed movement Or in static scene.In high-speed mobile scene, the received signal quality of terminal device may occur quickly Change (fluctuating very big), if for example, terminal device periodically determines received signal quality, front and rear two Having a long way to go between the received signal quality of secondary determination, by the gap and the cycle for determining received signal quality Between the received signal quality velocity of wave motion that is reflected of ratio it is also very big.In low speed movement or static In scene, the received signal quality of terminal device may occur slowly to change even constant, if for example, Terminal device periodically determines received signal quality, then the gap between the front and rear received signal quality for determining twice Less even without gap, reflected by the ratio between the cycle of the gap and determination received signal quality Received signal quality the velocity of wave motion also very little, even zero come.It should be apparent to a person skilled in the art that Scene residing for terminal device is not limited only to high-speed mobile scene, low speed mobile context and static scene.Root According to the translational speed or current state of terminal device, other scenes may further be provided.

No matter which kind of scene terminal device is in, in a kind of possible implementation, what method 300 determined The need for beam angle adjusting parameter should can adapt to concrete scene.For example, in high-speed mobile scene, The beam angle adjusting parameter that method 300 determines should ensure that terminal device is (such as pre- in a period of time If time span) in all the time according to the beam angle adjusting parameter adjust after wave beam coverage it It is interior, and be unlikely to need frequently to adjust wave beam because of the coverage of the wave beam after user departs from adjustment quickly Width.In other words, the beam angle adjusting parameter for determining according to method 300 is adjusted to the width of wave beam Whole, the wave beam that adjustment is obtained should not can just cover the position that terminal device is currently located, and be also contemplated that After terminal device movement a period of time, the scope that wave beam is covered obtained in adjustment is remained able to. Therefore, the scope that the wave beam that adjustment is obtained is covered should be greater than just covering what terminal device was currently located The scope that the wave beam of position is covered.Therefore, compared to low speed mobile context and static scene, terminal device is worked as When in high-speed mobile scene, the adjustment amplitude that beam angle adjusting parameter to be reflected should be bigger.Example Such as, when beam angle adjusting parameter is to expect the beam angle number of degrees, compared to low speed mobile context and static field The expectation beam angle number of degrees under scape, high-speed mobile scene should be bigger.So, just can guarantee that terminal Equipment is still within the corresponding beam coverage of the expectation beam angle number of degrees after movement a period of time.

If wanting it is determined that scene during beam angle adjusting parameter residing for reference terminal equipment, method The various corresponding relations being related to during 300 descriptions, such as but not limited to received signal quality and expectation wave beam Corresponding relation between the width number of degrees, the corresponding relation between received signal quality and expectation beam angle numbering And the corresponding relation between beam angle numbering and the beam angle number of degrees, it is likely that needs set according to terminal Standby residing scene is respectively provided with.Additionally, above-described other specification, such as but not limited to predetermined threshold value With default adjusting step, it is configured also dependent on the scene residing for terminal device.In this case, eventually End equipment can be according to residing for itself scene, need to use during the determination for determining beam angle adjusting parameter Corresponding relation and parameter.

During implementing, the scene residing for terminal device can be indicated by scene identity.Terminal sets It is standby itself can be determined according to the degree of fluctuation of received signal quality residing for scene, so that it is determined that scene identity. The degree of fluctuation of received signal quality can adopt in various manners to determine.If for example, terminal device is periodically true Determine received signal quality, then between the received signal quality that above-mentioned fluctuation situation determines twice before and after being presented as Gap, by the gap and determine received signal quality cycle between the reception that is reflected of ratio believe Number quality fluctuation speed, or received signal quality variance.Terminal device and access device can store reception Corresponding relation between the degree of fluctuation and scene identity of signal quality, to determine correspondence according to degree of fluctuation Scene.

Generally, access device can set initial scene for terminal device, and the scene identity of the scene is sent To user.During implementing, access device can by cell-specific (cell-specific) signaling, Terminal device group (UE (User Equipment) group-specific) dedicated signaling or terminal device (UE-specific) dedicated signaling, scene identity is sent to terminal device.

When terminal device judges that residing scene changes, terminal device can also feed back to access device and become The scene identity of the scene after change.Terminal device can individually feed back scene identity, additionally, scene identity can be wrapped It is contained in beam angle adjusting parameter and feeds back to access device.
