Fig. 2 is the schematic flow chart of the method 200 of the scanning beam of the embodiment of the present invention.As shown in Fig. 2, this method 200 includes:
210, when terminal device rotates behavior, the first instruction information is sent to the network equipment.
Specifically, sending the first instruction information to the network equipment when terminal device rotates behavior, which is used to indicate the class letter of the rotation behavior, so that the network equipment is that the terminal device distributes running time-frequency resource according to the class letter.
That is, the class letter of the rotation behavior of the first instruction information instruction that the network equipment can be sent by receiving terminal apparatus, distributes running time-frequency resource for the terminal device.
Optionally, terminal device can send channel state information (Channel State Information, CSI) to the network equipment, which may include the first instruction information.
Optionally, before 210, terminal device can send third to the network equipment and indicate that information, third instruction information are used to indicate the function that the terminal device has identification rotation behavior.For example, terminal device sends third instruction information when starting first time, to the network equipment.In another example terminal device periodic network equipment sends third instruction information etc..
It should be understood that the class letter in the embodiment of the present invention, can refer to the grade of the rotation behavior, it can also be only a mark for classifying to the rotation behavior.The embodiment of the present invention is not especially limited.
It should also be understood that the rotation behavior in the embodiment of the present invention refers to the translation and/or rotation that the terminal device occurs in solid space
Turn, alternatively, the translation and/or rotation that occur in plane space.Wherein, translating and/or rotating is only a kind of incidence relation for describing affiliated partner, indicates may exist three kinds of relationships.Specifically, translation and/or rotation can indicate: only translating, exist simultaneously translation and rotation, only rotate these three situations.
For example, terminal device (rigid body) can be divided into 6 freedom degrees in a free solid space as one embodiment.That is, terminal device can translate on 3 orthogonal directions, it can also be rotated by axis of 3 orthogonal directions, thus have 6 freedom degrees.
Specifically, as shown in figure 3, by taking three-dimensional system of coordinate as an example, x-axis is perpendicular to mobile phone screen, y-axis is parallel to the short side of mobile phone screen, and z-axis is parallel to the long side of mobile phone screen, and 6 freedom degrees are respectively as follows: to be translated along x-axis, translates along y-axis, it translates along z-axis, is rotated around x-axis, rotated around y-axis, rotated around z-axis.
In another example, as another embodiment, terminal device (rigid body) is restrained in a plane, then there was only three degree of freedom in this face, i.e., terminal device can also rotate by axis of the vertical direction of the plane to translate on planar 2 orthogonal directions, thus have 3 freedom degrees.
Specifically, by taking two-dimensional coordinate system as an example, if this face is the X-Y plane in Fig. 3, this 3 freedom degrees be respectively as follows: along the moving of X-axis, along Y-axis move and rotation about the z axis.
It should be noted that above-mentioned 6 kinds of freedom degrees and 3 kinds of freedom degrees are the exemplary descriptions to the rotation behavior of terminal device in the embodiment of the present invention, example of the present invention is not limited to this.
Optionally, in embodiments of the present invention, terminal device can generate the first instruction information by obtaining the rotational parameters of the rotation behavior.Wherein, which refers to the parameter value that the rotation behavior to the terminal device is quantified.For example, the rotational parameters may include at least one in angular speed, angular acceleration and rotational angle.
Specifically, terminal device obtains the rotational parameters of the rotation behavior by sensor.For example, acceleration sensor, gyroscope and earth inductor etc. are used to detect the motor behavior of carrier.Wherein, gyroscope is called angular-rate sensor, is to be different from accelerometer (G-sensor), rotational angular velocity when his measurement physical quantity is deflection, inclination.On the terminal device, complete 3D movement only can not be measured or reconstructed with accelerometer, do not detect the movement of rotation, G-sensor can only detect axial line movement.But gyroscope then can do good measurement to the movement of rotation, deflection, and the actual act of user, the i.e. corresponding rotational parameters of rotation behavior of terminal device can be thus judged with Accurate Analysis.This can be implemented to those skilled in the art, and the embodiment of the present invention does not repeat.
Below for terminal device after knowing these rotational parameters, it is illustrated according to the implementation that these rotational parameters generate the first instruction information.
Optionally, in embodiments of the present invention, terminal device can be according to the rotational parameters and the first mapping relation information, the class letter of the rotation behavior is determined first, wherein, first mapping relation information may include at least one class letter rotational parameters corresponding at least one class letter；Then, which is generated according to the class letter.For example, the first instruction information includes the class letter.
For example, above-mentioned class letter can be the information of 1bit.Specifically, when the rotational parameters of terminal device are more than that first threshold is less than second threshold, this class letter is 1, and when rotational parameters are more than second threshold and are less than third threshold value, this class letter is 2, and so on.
It should be understood that above-mentioned class letter is that 1bit information is merely illustrative.The embodiment of the present invention is without being limited thereto, for example, the class letter can also directly include the rotational parameters.
220, the response message of first instruction message of network equipment transmission is received, which includes the instruction information of the running time-frequency resource
Specifically, terminal device receives the response message of first instruction message of network equipment transmission, which disappears
Breath includes the instruction information of the running time-frequency resource.
In other words, after the network equipment receives the first instruction information that terminal device is sent, the class letter according to the rotation behavior of first instruction message instruction is terminal device distribution running time-frequency resource；And the response message of the first instruction information is generated according to the running time-frequency resource, which includes the instruction information of the running time-frequency resource.The response message of the first instruction information is sent to the terminal device.
Optionally, the network equipment determines the quantity of candidate beam according to the class letter and the second mapping relations, which includes the quantity of the corresponding candidate beam of each class letter at least one class letter and at least one class letter；According to the quantity of the candidate beam, the running time-frequency resource is distributed for the terminal device.
Specifically, the network equipment in the embodiment of the present invention can determine that the quantity for needing the candidate beam scanned, the quantity of the candidate beam then scanned as needed are that terminal device distributes running time-frequency resource according to the class letter in the first instruction information.
230, according to the instruction information of the running time-frequency resource, on the running time-frequency resource, signal is sent to the network equipment by least one candidate beam
Specifically, terminal device is according to the instruction information of the running time-frequency resource, on the running time-frequency resource, signal is sent to the network equipment by least one candidate beam, so that the network equipment determines strongest first wave beam of signal gain in this at least one candidate beam.Wherein, which is the part wave beam in the configuration wave beam of the terminal device.In other words, the network equipment receives the terminal device by this at least one candidate beam and sends signal, wherein at least one candidate beam is the part wave beam in the configuration wave beam of the terminal device；Also, by the intensity for comparing signal at least one candidate beam, strongest first wave beam of signal gain can be determined at least one candidate beam.
The basic ideas of beamforming technique are, divide space into multiple regions, terminal device is in some specific timeslice, to one to several regions issue wave beam, pass through some time piece in this way, wave beam can be issued in whole spaces, i.e. the network equipment can also scan whole spaces, and all wave beams that can issue terminal device in the embodiment of the present invention are referred to as the configuration wave beam of the terminal device.It is using the advantages of beamforming technique: antenna energy is focused on a direction, more strong signal on some direction can be obtained, reach more preferable communication distance or rate.But certain several direction can only be focused on.
Since signal decrease may have multiple situations.For example, signal blocks, i.e. terminal device and network and the network equipment all do not move, but there is shelter among the network equipment and terminal device；Alternatively, resulting in centre since the movement of user causes terminal device to send movement and being blocked.In another example terminal device rotates, such as 90 degree of user's pirouette, other conditions do not change.
But, for the network equipment, the reason of being not aware that the decrease or interruption of signal, when can only weaken or interrupt in discovery communication, it is scanned comprehensively by the configuration wave beam to terminal device, the strongest wave beam of signal gain is redefined, communication is re-established, this can occupy very more running time-frequency resources.
The method of the scanning beam of the embodiment of the present invention, it can make the network equipment that the part wave beam in configuration wave beam to terminal device only be needed to be scanned by rotational parameters,, determine strongest first wave beam of signal gain, in turn, when terminal device sends rotation behavior, the network equipment is re-established in communication process, the effectively less occupancy of running time-frequency resource.
It should be noted that each configuration wave beam of terminal device is corresponding with a wave beam mark.For example, the configuration wave beam of terminal device is 8, i.e. one wave beam of every 45 ° of configurations, wherein this 8 wave beams can respectively correspond to a mark.For example, this 8 wave beams corresponding wave beam mark difference 0#, 1#, 2#, 3#, 4#, 5#, 6#, 7#, then when terminal device sends signal by 1# wave beam, the network equipment carries out reception signal by scanning 1# wave beam.It should also be understood that in the embodiment of the present invention
Candidate beam refer to terminal device according to rotational parameters determine the stronger wave beam of possible signal gain.
In embodiments of the present invention, optionally, in the configuration wave beam of the terminal device, terminal device can determine the corresponding wave beam mark of at least one candidate beam according to the running time-frequency resource and the rotational parameters；According to the corresponding wave beam mark of at least one candidate beam, the signal is sent at least one candidate beam.In other words, the network equipment can determine that the quantity for needing the candidate beam scanned, the quantity of the candidate beam then scanned as needed are that terminal device distributes running time-frequency resource according to the class letter in the first instruction information.
Specifically, terminal device calculates the maximum quantity for the wave beam that can be sent by the running time-frequency resource indicated in the response message after receiving the response message of the first instruction information of network equipment transmission；According to the rotational parameters and the maximum quantity, the corresponding wave beam mark of at least one candidate beam is determined；Then, it is identified according to the corresponding wave beam of at least one candidate beam, sends the signal at least one candidate beam.
Optionally, which is M, and terminal device can determine the rotational angle of the rotation behavior according to the rotational parameters；Second wave beam of the terminal device is compensated into the rotational angle according to first direction and obtains third wave beam, which is that used wave beam when the rotation behavior does not occur for the terminal device, which is the opposite direction of the rotation behavior；By the corresponding wave beam mark of M wave beam for closing on the third wave beam, it is determined as the corresponding wave beam mark of at least one candidate beam.
For example, rotation can be clockwise or counterclockwise in the system of plane motion.
Assuming that the maximum quantity is M, the wave beam that terminal device uses before the behavior of rotating is identified as 2# wave beam, its rotation behavior is to rotate clockwise 30 °, then terminal device is when determining that the possible wave beam of candidate beam identifies, it can be by 2# wave beam according to 30 ° of rotation counterclockwise, the corresponding third wave beam in the compensated region of 2# wave beam is obtained, the corresponding wave beam of M wave beam for closing on third wave beam is identified, is determined as the corresponding wave beam mark of at least one candidate beam.
It is above-mentioned only illustratively to be illustrated that the embodiment of the present invention carry out in three dimensions angle and not grow by the system of plane motion and angle compensation.Can also be compensated by angular speed and angular acceleration etc..The embodiment of the present invention is not especially limited.
It should be understood that terminal device can first be determined to the maximum quantity of the candidate beam sent when determining that the corresponding wave beam of at least one candidate beam identifies according to running time-frequency resource, then directly determine candidate beam mark.It can also be first ranked up according to candidate beam of the rotational parameters to terminal device, then directly determine that the corresponding wave beam of candidate beam identifies in order according to running time-frequency resource, the embodiment of the present invention is not especially limited.
In embodiments of the present invention, optionally, after the network equipment determines the corresponding wave beam mark of the first wave beam, second indication information can be sent to terminal device, which is used to indicate the corresponding wave beam mark of first wave beam.
It should be noted that, in embodiments of the present invention, first instruction information is used to indicate the class letter of rotation behavior, and second indication information is used to indicate the wave beam mark of first wave beam, and third instruction information is used to indicate the function whether terminal device has detection rotation behavior.
That is, " first ", " second " and " third " is not construed as limiting the range of the embodiment of the present invention just to distinguish different information, and to the not restriction such as the quantity of information, type.
