It is well suited to use multiple antenna technologies to increase coverage and capacity on such a high spectrum. Therefore, Massive MIMO (MM) is undoubtedly one of the important means to improve the efficiency of 5G spectrum.

The beamforming technology in related cellular communication mainly performs the direction direction problem of beamforming. For example, in LTE, the channel is determined according to channel feedback (FDD system) or according to channel reciprocity (TDD system). The signal thus changes the direction of the beam to the purpose of beamforming such that the direction of the beamforming changes according to the direction of movement of the terminal within the cell.

detailed description

In various embodiments of the present disclosure, the first device acquires beam configuration information, where at least two beams of the beam configuration information have different beam widths; and acquires link information for communicating with the second device; A beam width corresponding to the link information is determined in the beam configuration information, and a beam corresponding to the beam width is determined as a beam that communicates with the second device.

The implementation of the technical solution will be described in detail below with reference to the accompanying drawings.

Embodiment 1

A first embodiment of the present disclosure provides a method for allocating a beam, which is applied to a first device. As shown in FIG. 1, the method includes:

S101. When acquiring beam configuration information, at least two beams in the beam configuration information have different beam widths.

Here, the first device may include a communication device that communicates with the base station, the TRP, the terminal, and the like. When the first device is a base station and a TRP, the second device is a terminal; when the first device is a terminal, the second device is a base station or a TPR. .

The first device has a multi-antenna array with beamforming capability, and can generate beams of various beam widths, and the beam width of each beam can be determined by the weighting coefficient of the array elements of the antenna array corresponding to each beam. When the weighting coefficients of the array elements of the antenna array are different, beams of different beam widths can be generated.

The first device acquires beam configuration information including information such as the number of beams, the beam index number, and the beam width corresponding to each beam. In the beam configuration information, at least two beams have different beam widths, where the beam can pass through the beam. The index number indicates a different beam. Here, the configured beam In the configuration information, the widths of the beams may be different, or the beams of the partial beams may be the same. For example, the beam configuration information of a device is beam 1, beam 2, beam 3, and beam 4. The corresponding beam widths are beam width 1, beam width 2, beam width 3, and beam width 4. There are at least two different values for the beam width 1 to the beam width 4.

S102. Obtain link information for communicating with the second device.

When the first device communicates with the second device, obtain link information of the link that the two devices communicate with; the communication here may be a data communication after the first device establishes a connection with the second device, or may be the first device Accessing the second device or the second device to access the communication performed by the first device. Here, when a wireless connection is established between the first device and the second device, there is communication between the two, and there is a link for performing communication. The communication that the first device accesses the second device or the second device accesses the first device may be the communication that the terminal accesses the base station or the terminal accesses the TRP.

And obtaining the link information for communicating with the second device, at least one of: acquiring an amount of link transmission service data with the second device; acquiring a link with the second device RRC connection status: wherein the RRC connection status includes an idle status or a connection status. The link parameter that the first device obtains the link communication with the second device may be the link transmission service data volume or the link RRC connection state, and may also acquire the link RRC connection state and the link transmission service data amount. When the link RRC connection state and the link transmission service data amount are simultaneously acquired, if the acquired link RRC connection state is the idle state, the link transmission service data amount may be considered to be zero.

S103. Determine a beam width corresponding to the link information from the beam configuration information, and determine a beam corresponding to the beam width as a beam that communicates with the second device.

After obtaining the link parameters, the terminal allocates a beam for communication according to the obtained link parameters, for example:

Determining a beam width corresponding to the link information from the beam configuration information includes: selecting, according to an allocation policy, a beam width corresponding to the amount of the transmission service data from the beam configuration information; wherein the allocating In the policy, the value of the beamwidth corresponding to the first transmission service data volume is greater than the value of the beamwidth corresponding to the second transmission service data volume, and the first transmission service data volume is smaller than the second transmission service data volume.

Determining a beam width corresponding to the link information from the beam configuration information further includes: selecting a beam width corresponding to the RRC connection state from the beam configuration information according to an allocation policy; wherein the allocating In the policy, when the RRC connection state is the idle state, the corresponding beam width is the first beam width; when the RRC connection state is the connected state, the corresponding beam width is the second beam width; and the first beam width is The value is greater than the value of the second beam width.

When the acquired parameter is the amount of the transmission service data of the link, the beam used by the first terminal and the second terminal to perform communication is allocated according to the data traffic of the link, where the allocation strategy of the allocated beam is a preset allocation rule: A beam with a relatively narrow beam width is allocated for a link with a large amount of traffic data, and a beam with a relatively large beam width is allocated for a link with a large amount of data for transmission. Here, the amount of data of the transport service can be compared with the same device. The amount of transmission service data of the link in different time segments of the link is determined, and may also be determined according to the amount of transmission service data of the links of different devices in the same time period.

For example, for the same time period, the second device that communicates with the first device includes device A and device B. The amount of transmission service data of the link communicating with the device A is D _A , and the amount of transmission service data of the link communicating with the device B is D _B , D _A > D _B , and the beam allocated by the device A is The beamwidth is less than the beamwidth of the beam allocated for device B. For another example, the amount of transmission service data of the link that the second device device C communicates with the first device with the first device is D _C1 , and the transmission of the link between the device C and the first device after a period of time The traffic data volume is D _C2 and D _C1 > D _C2 , and the beam for communicating the device C with the first device is switched from beam 1 to beam 2, wherein the beam width of beam 1 is smaller than the beam width of beam 2.

When the obtained link parameter is the RRC connection state of the link, the beam used by the first terminal and the second terminal to perform communication is allocated according to the RRC connection state, where the beam width of the beam allocated by the idle state and the connection state is different, The beamwidth of the beam allocated for the link in the idle state is greater than the beamwidth allocated for the link in the connected state. Here, the beamwidth of the allocated beams may be relative to different states of the same device, or may be relative to different states between different devices. For example, when the first device communicates with the device D, the beam width of the beam allocated for the link in the idle state is greater than the beam width of the beam allocated for the link in the connected state; for example, when the first device and the device E and When the device F performs communication, the RRC connection state of the link in which the first device communicates with the device E is in an idle state, and the RRC connection state of the link in which the first device communicates with the device F is in a connected state, The beamwidth of the beam allocated by the link of the communication is greater than the beamwidth of the beam allocated for the link communicating with device F.

And when the amount of the transmission service data and the RRC connection status of the link for communicating with the first device is not changed, and the distance between the communication between the first device and the second device is changed, the first device and the second device are allocated. The beam used by the communicating link is switched, and the beamwidths of the two beams that are switched can be kept consistent.

In an embodiment of the present disclosure, the method further includes: setting a measurement period according to the RRC connection state; wherein,

When the RRC connection state is the idle state, the set measurement period is the first measurement period; when the RRC connection state is the connected state, the set measurement period is the second measurement period; the value of the first measurement period Greater than the value of the second measurement period. Here, according to different RRC connection states, the set measurement periods are different, so that when the RRC connection state is different, the beam widths of the beams are different. The measurement period used is different.

For example, when the RRC connection state of the link between the terminal and the base station is idle, a beam with a wide beam width can be allocated, and the measurement signal of the channel quality measurement signal, the synchronization signal, and the like is transmitted through the allocated beam. When the measurement period of the measurement signal is relatively large, it can ensure that the frequency of measurement is lower when the terminal moves, and the frequency of switching between the beams is reduced. When the RRC connection status of the link between the terminal and the base station is in the connection state, a beam with a narrow beam width can be allocated, and the measurement signal such as the channel quality measurement signal and the synchronization signal is transmitted through the allocated beam, and when the measurement signal is transmitted. When the measurement period is relatively small, it can ensure that the terminal can switch to the beam for communication in time when moving, thereby improving data transmission efficiency.

In the actual application, when the beam configuration information is set, the beam allocation information may be directly generated according to the allocation policy and the beam configuration information, where the beam allocation information may include a beam index number, a beam width, a corresponding data transmission rate, and a corresponding In the RRC connection state or the like, when the beam configuration is performed, the beam is directly allocated according to the beam allocation information and the beam allocation information corresponding to the allocation policy.

In the embodiment of the present disclosure, a device including different beam widths is configured for the device for performing communication, and the link information is used to communicate from the beams of different beam widths according to link information such as the amount of transmission service data and the RRC connection state of the link. The corresponding beams are allocated, so that the beams that communicate between the devices can be adjusted according to the link parameters, thereby reducing the energy consumption of the devices. When the amount of transmission traffic of the link is small, by configuring a wider beamwidth, the measurement period can be increased, and the switching frequency can be reduced, thereby saving power and providing a user experience. When the amount of transmission traffic of the link is large. By configuring a narrower beam, the channel quality is improved, thereby improving data transmission efficiency.

Embodiment 2

In this embodiment, the first device is a TRP as an example, and the distribution beam provided by the embodiment of the present disclosure is used. The method is explained.

In the case of a higher frequency spectrum, since the coverage of a network node (such as a base station) is limited, if the cell coverage radius is very small according to the definition of the traditional cell, the transmission and reception point TRP is generally introduced in the 5G, in a TRP situation. In the following, it is equivalent to a conventional base station, but in some cases, a cell may be covered by more than one TRP (equivalent to a base station), but is jointly covered by multiple TRPs, thereby increasing the coverage radius of the cell.

The TRP includes a multi-antenna array with beamforming capabilities, can generate beams of multiple beamwidths, and the resulting beamwidth can be configured, and the devices communicating with the TRP include UE1 and UE2. As shown in FIG. 2, the TRP includes beams of various beam widths: beam j, beam j+1, beam i, beam i+1, and beam i+2. Among them, the beam widths of beam i, beam i+1 and beam i+2 are narrower for these types of beams, and the beam widths of beam j and beam j+1 are wider.

When the TRP performs beam allocation, the link parameter of the link that the TRP communicates with the UE is obtained: the RRC state of the link, where the acquired RRC connection state includes an idle state and a connected state.

The TRP configures the beamwidth according to the RRC state of the UE. For example, when the RRC connection state is in an idle state, a wider beamwidth is used, and for example, a channel quality measurement signal and a synchronization signal are transmitted on the allocated beam. The measurement signal, the measurement period for transmitting the measurement signal can be set longer; when the RRC state is in the connected state, a narrower beam width is used. A measurement signal such as a channel quality measurement signal and a synchronization signal is transmitted on the allocated beam, and the measurement period in which the measurement signal is transmitted may be set shorter.

In the idle state, the beam width is wider, and the measurement period is set to be relatively longer. When the UE moves, the frequency of measurement is lower, and the switching frequency is lower, thereby saving energy.

In the connected state, the beam width is narrow, and the measurement period is set relatively short. When the UE moves, the corresponding beam with good channel state can be obtained in time. Thereby improving the efficiency of data transmission.

Here, the beam configuration information of the TRP may be broadcast to the terminal in the form of bits in the form of broadcast system information. When a terminal enters the initial access of the cell, the beam configuration information of the TRP can be obtained through system information. The beam configuration information of the TRP can also be sent to the terminal by using a dedicated channel after the terminal randomly accesses.

The beam allocation information of the TRP is as shown in Table 1, wherein the beams of the TRP have different beam widths, including: beamwidth 1, beamwidth 2, beamwidth i. The beams in the beam configuration information are arranged according to the beam width from the largest to the smallest, that is, the beam width 1 corresponds to the maximum beam width, and the beam width i, the corresponding beam width is the smallest. At this time, the data traffic of the link corresponding to each beam width is determined according to the allocation policy and the beam configuration information, for example, the corresponding beamwidth is allocated according to the amount of transmission service data with the terminal. Here, as shown in Table 1, M ₁ , M ₂ ... M _i-1 respectively indicate the magnitude of the amount of traffic data, and the values of M ₁ , M ₂ ... M _i-1 are sequentially increased. When the amount of transmission service data between the TRP and the terminal is obtained, the beam allocation is performed according to the beam allocation information shown in Table 1. When the amount of service data is small, a wide beam path is allocated, and when the amount of service data is large, the allocation is relatively large. Large beam path. For example, when the number of transmission services of the link in which the TRP communicates with the terminal is X, and M ₂ <X<M ₁ , the beam width of the beam used by the determined TRP to communicate with the terminal is the beam width 2.

In this embodiment, a method for allocating a beam provided by an embodiment of the present disclosure is described by taking a first device as a UE as an example.

The UE includes a multi-antenna array with beamforming capabilities, can generate beams of multiple beamwidths, and the resulting beamwidth can be configured. It contains beam paths with multiple beamwidths. Only two beamwidth beams are shown in this embodiment, one being a narrower beamwidth and the other being a wider beamwidth. As shown in FIG. 2, the UE includes beams of various beam widths: beam j, beam j+1, beam i, beam i+1, and beam i+2. The beam widths of the beam i, the beam i+1, and the beam i+2 are narrow, and the beam widths of the beam j and the beam j+1 are wide.

The terminal configures the beamwidth according to the RRC state of the link between the terminal and the base station, and adopts a wider beamwidth when the RRC state is in the idle state (Idle state); when the RRC state is in the connected state, Narrower beamwidth.
