The following describes the embodiments in further detail with reference to the accompanying drawings.
Example one
An embodiment of the present invention provides a method for allocating a beam, which is applied to a first device, and as shown in fig. 1, the method includes:
s101, when beam configuration information is obtained, the beam widths corresponding to at least two beams in the beam configuration information are different;
here, the first device may include a communication device that communicates with a base station, a TRP, a terminal, etc., and when the first device is the base station, the TRP, the second device is the terminal; when the first device is a terminal, the second device is a base station or a TPR.
The multi-antenna array with the beam forming capability of the first device can generate beams with various beam widths, and the beam width of each beam can be determined by the weighting coefficient of the array element of the antenna array corresponding to each beam. When the array elements of the antenna array have different weighting coefficients, beams with different beam widths can be generated.
The first device obtains its own beam configuration information including information such as the number of beams, beam index numbers, and beam widths corresponding to the beams, wherein in the beam configuration information, the beam widths corresponding to at least two beams are different, and here, different beams can be indicated by the beam index numbers. Here, in the allocated beam allocation information, the widths of the respective beams may be different, or the beams of the partial beams may be the same. Such as: the beam configuration information of a certain device is beam 1, beam 2, beam 3, and beam 4, and the corresponding beam widths are beam width 1, beam width 2, beam width 3, and beam width 4, respectively. Wherein there are at least two different values for beamwidth 1 to beamwidth 4.
S102, obtaining link information communicated with the second equipment;
when the first equipment communicates with the second equipment, link information of a link for communicating the first equipment and the second equipment is acquired; the communication here may be data communication after the first device establishes connection with the second device, or may be communication performed by the first device accessing the second device or the second device accessing the first device, where when the wireless connection is established between the first device and the second device, there is communication between the first device and the second device, and there is a link for performing communication. The communication performed by the first device accessing the second device or the second device accessing the first device is specifically the communication performed by the terminal accessing the base station or the terminal accessing the TRP.
The obtaining of the link information for communicating with the second device includes at least one of: acquiring link transmission service data volume between the second equipment and the second equipment; acquiring an RRC connected state of a link with the second device: wherein the RRC connected state comprises: an idle state or a connected state. The link parameter for the first device to perform link communication with the second device may be a link transmission traffic data volume or a link RRC connection state, or may also be obtained simultaneously. When the link RRC connection state and the link transmission traffic data amount are simultaneously acquired, the link transmission traffic data amount may be considered to be zero when the acquired link RRC connection state is the idle state.
S103, determining a beam width corresponding to the link information from the beam configuration information, and determining a beam corresponding to the beam width as a beam for communicating with the second device.
After the link parameters are obtained, allocating beams for communication to the terminal according to the obtained link parameters, specifically:
the determining, from the beam configuration information, a beam width corresponding to the link information includes: selecting a beam width corresponding to the transmission service data volume from the beam configuration information according to an allocation strategy; in the allocation strategy, a value of a beam width corresponding to a first transmission service data volume is greater than a value of a beam width corresponding to a second transmission service data volume, and the first transmission service data volume is smaller than the second transmission service data volume.
The determining the beam width corresponding to the link information from the beam configuration information further comprises: selecting a beam width corresponding to the RRC connection state from the beam configuration information according to an allocation strategy; in the allocation strategy, when the RRC connection state is an idle state, the corresponding beam width is a first beam width; when the RRC connection state is a connection state, the corresponding beam width is a second beam width; the value of the first beamwidth is greater than the value of the second beamwidth.
When the acquired parameter is the transmission service data volume of the link, allocating a beam used by the first terminal and the second terminal for communication according to the data service volume of the link, wherein an allocation strategy of the allocated beam is a preset allocation rule: and allocating a beam with a narrower beam width for the link with large transmission service data amount, and allocating a beam with a wider beam width for the link with large transmission service data amount.
Such as: for the same time period, the second device communicating with the first device includes device a and device B. Wherein the number of transmission services of the link communicating with the device AData volume is DAThe transmission traffic data volume of the link communicating with the device B is DB，DA>DBThen the beamwidth of the beam allocated for device a is smaller than the beamwidth of the beam allocated for device B. For another example: the transmission service data volume of a link, which is communicated with the first equipment by the second equipment C, is DC1After a period of time, the transmission traffic data volume of the link where the device C communicates with the first device is DC2And D isC1>DC2The beam of the device C communicating 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.
And when the acquired link parameter is the RRC connection state of the link, allocating a beam used by the first terminal and the second terminal for communication according to the RRC connection state, wherein the beam widths of the beams allocated in the idle state and the connection state are different, and the beam width of the beam allocated to the link in the idle state is larger than the beam width allocated to the link in the connection state. Here, the beam width size of the allocated beam may be with respect to different states of the same device or with respect to different states between different devices. Such as: when the first device communicates with the device D, the beam width of the beam allocated to the idle-state link is greater than the beam width of the beam allocated to the connection-state link; for another example: when the first device communicates with the device E and the device F, the RRC connection state of the link where the first device communicates with the device E is an idle state, and the RRC connection state of the link where the first device communicates with the device F is a connection state, then the beam width of the beam allocated to the link where the first device communicates with the device E is greater than the beam width of the beam allocated to the link where the first device communicates with the device F.
When the transmission traffic data volume and the RRC connection state of the link for communicating with the second device do not change and the distance between the first device and the second device changes, the beams used by the link for communicating allocated to the first device and the second device are switched, and the beam widths of the two switched beams can be kept the same.
In the embodiment of the present invention, the method further includes: setting a measurement period according to the RRC connection state; wherein,
when the RRC connection state is an idle state, setting a measurement period as a first measurement period; when the RRC connection state is a connection state, setting a measurement period as a second measurement period; the value of the first measurement period is greater than the value of the second measurement period. Here, the measurement period is set to be different depending on the RRC connection state, so that the beam width of the beam is different and the measurement period used is different when the RRC connection state is different.
Such as: when the RRC connection state of the link between the terminal and the base station is an idle state, a beam with a wider beam width can be allocated, the transmission of measurement signals such as channel quality measurement signals and synchronization signals can be carried out through the allocated beam, and when the measurement period for transmitting the measurement signals is relatively large, the measurement frequency is lower when the terminal moves, and the switching frequency between the beams is reduced. When the RRC connection state of the link between the terminal and the base station is a connection state, a beam with a narrower beam width can be distributed, the distributed beam is used for sending measurement signals such as channel quality measurement signals and synchronization signals, and when the measurement period for sending the measurement signals is relatively small, the terminal can be ensured to be switched to the beam for communication in time when moving, and the data transmission efficiency is improved.
In practical application, when the beam configuration information is set, the beam allocation information can be directly generated according to the allocation policy and the beam configuration information, wherein the beam allocation information can include a beam index number, a beam width, a corresponding data transmission rate, a corresponding RRC connection state, and the like, so that when the beam configuration is performed, the beam is directly allocated according to the beam allocation information corresponding to the beam configuration information and the allocation policy.
In the embodiment of the invention, beams with different beam widths are configured for communication equipment, and corresponding beams are allocated for the communication links from the beams with different beam widths according to link information such as transmission service data volume and RRC connection state of the links, so that the beams for communication between the equipment can be adjusted according to link parameters, and the energy consumption of the equipment is reduced. Furthermore, when the transmission service data volume of the link is small, the measurement period can be increased and the switching frequency is reduced by configuring the wider beam width, so that the electric quantity is saved, the user experience is provided, and when the transmission service data volume of the link is large, the channel quality is improved by configuring the narrower beam, so that the data transmission efficiency is improved.
Example two
In this embodiment, the method for allocating beams provided by the embodiment of the present invention is further described by taking the first device as the TRP as an example.
It should be noted that in the case of higher frequency spectrum, because the coverage area of a network node (e.g. a base station) is limited, and the cell coverage radius is very small if defined according to the conventional cell, the concept of a transmission reception point TRP is generally introduced in 5G, and in the case of one TRP, it is equivalent to the conventional base station, but in some cases, a cell may be covered by more than one TRP (equivalent to the base station) and is covered by a plurality of TRPs jointly, thereby increasing the coverage radius of the cell.
The TRP includes a multi-antenna array with beamforming capability, beams of various beamwidths may be generated, and the generated beamwidths may be configured, and devices in communication with the TRP include UE1 and UE 2. As shown in fig. 2, the TRP includes beams with various beam widths: beam j, beam j +1, beam i +1, and beam i + 2. Among them, the beam widths of the beam i, the beam i +1 and the beam i +2 are narrower, and the beam widths of the beam j and the beam j +1 are wider.
When the TRP performs beam allocation, acquiring link parameters of a link for communication between the TRP and the UE: and the RRC state of the link, wherein the acquired RRC connection state comprises an Idle state (Idle state) and a connected state (connected state).
The TRP configures a beam width according to an RRC state with the UE, specifically: when the RRC connection state is in an Idle state (Idle state), a wider beam width is used, and a measurement signal such as a channel quality measurement signal and a synchronization signal is transmitted on the allocated beam, and a measurement period for transmitting the measurement signal may be set longer; when the RRC state is in a connected state, a narrower beam width is employed. A measurement signal such as a channel quality measurement signal, a synchronization signal, is transmitted on the allocated beam, and a measurement period for transmitting the measurement signal may be set shorter.
In an idle state, the beam width is wide, the measurement period is relatively long, the measurement frequency is low when the UE moves, and the switching frequency is also low, so that the purpose of energy conservation is achieved.
In the connected state, the beam width is narrow, the measurement period is relatively short, and when the UE moves, the UE can obtain the corresponding beam in a good channel state in time. Thereby improving the efficiency of data transmission.
Here, the beam configuration information of the TRP may be broadcast in the form of bits to the terminal by broadcasting system information. When a terminal enters a cell for initial access, the terminal can obtain the beam configuration information of the TRP through system information. The beam configuration information of the TRP may also be transmitted to the terminal using a dedicated channel after the terminal has random access.
When the beam allocation information of the TRP is shown in table 1, wherein the beams of the TRP have different beam widths, the method includes: beamwidth 1, beamwidth 2 … beamwidth i. The beams in the beam configuration information are arranged from large to small according to the beam width, that is, the beam width 1 corresponds to the largest beam width, and the beam width i corresponds to the smallest beam width. At this time, each beam width is determined according to the allocation strategy and the beam configuration informationThe data traffic of the corresponding link, specifically, the corresponding beam width is allocated according to the transmission traffic data volume of the terminal. Wherein, as shown in Table 1, M1，M2…Mi-1Respectively representing the size of the traffic data amount, and M1，M2…Mi-1Are sequentially increased. When acquiring the transmission service data volume between the TRP and the terminal, allocating beams according to the beam allocation information shown in Table 1, allocating wider beam paths when the service data volume is smaller, and allocating larger beam paths when the service data volume is larger. Such as: when the transmission traffic quantity of a link where TRP communicates with a terminal is X, and M2<X<M1Then, the beam width of the determined TRP for communication with the terminal is beam width 2.
Table 1 beam allocation information
| Kind of beam width | Transmitting traffic data volume |
| Beam width 1 | Less than M1 |
| Beam width 2 | Greater than M1 and less than M2 |
| 。。。 | 。。。 |
| Beam width i | Greater than Mi-1 |
EXAMPLE III

The UE includes a multi-antenna array with beamforming capability, may generate beams of various beamwidths, and the generated beamwidths may be configured. It contains beam paths of various beamwidths. In this embodiment, only two beamwidths of beams are shown, one being a narrower beamwidth and the other being a wider beamwidth. As shown in fig. 2, the UE includes beams with various beam widths: beam j, beam j +1, 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 beam width according to the RRC state of a link between the terminal and the base station, and adopts a wider beam width when the RRC state is in an Idle state (Idle state); when the RRC state is in the linked state, a narrower beam width is employed.
