Description

Beam processing method, device and storage medium

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office, the application number is 201911089926.1, and the invention title is "a beam processing method, device, and storage medium" on November 8, 2019, the entire content of which is incorporated by reference In this application.

Technical field

This application relates to the field of communication technology, and in particular to a beam processing method, device, and storage medium.

Background technique

Compared with the low frequency band, the millimeter wave frequency band has a larger free bandwidth. The fifth generation mobile communication technology (5th generation mobile networks, 5G) adopts the millimeter wave frequency band to obtain a high transmission rate. But at the same distance, the millimeter wave frequency band has greater path loss than the low frequency band. Therefore, communication systems that use the millimeter-wave frequency band usually use large-scale array antennas, through which narrow beams are fired to obtain array gain and overcome the high path loss of the millimeter-wave frequency band. High-frequency propagation will also be affected by obstructions in the propagation path, introducing additional loss relative to the path loss. When high-frequency communication systems are applied to indoor coverage scenarios, indoor coverage scenarios include open indoor scenarios, such as airport and railway station halls, and indoor multiple partition scenarios, such as hotels, hospitals, and office buildings. For indoor open scenes, the main loss of signal propagation is path loss, and the sites that can be deployed are relatively sparse. For indoor multi-partition scenarios, the signal propagation will be blocked by walls, seats, etc., which will introduce additional propagation path loss. Therefore, the sites need to be deployed more densely.

Although a product can be applied to the above-mentioned multiple different scenarios, considering the diversity and uncertainty of the multi-partition scenario, it is usually planned with the coverage required by the open scenario. For example, based on the target reference signal received power (RSRP), the transmitter array gain can be derived, and then the antenna array selection and beam design can be performed. If all scenarios use the same beam, it may cause greater interference to the neighboring area. For example, if a site is deployed in a room, even if penetration loss is introduced due to the wall, it may cause greater interference to the neighboring area. Therefore, how to solve the neighboring cell interference problem caused by the above-mentioned fixed beam design has become an urgent problem to be solved.

Module to achieve the purpose of this application program.

When the current high-frequency communication system is applied to indoor coverage scenarios, indoor coverage scenarios include indoor open scenes and indoor multiple partition scenes. Due to the diversity and uncertainty of multi-partition scenarios, network planning and deployment are usually carried out first with the coverage required by the open environment. When planning and deploying the coverage required by the open environment, you can first determine the target reference signal received power RSRP_target corresponding to the coverage required by the open environment. The RSRP_target is the RSRP that the coverage required by the open environment is expected to be achieved. For example, it can be based on the edge rate. Determine the modulation and coding method of the edge, where the modulation and coding method has a mapping relationship with the signal to interference plus noise ratio (SINR), which can be obtained through link simulation, and then the required SINR is determined according to the modulation and coding method. Then determine the RSRP_target (for example, SINR*noise floor=RSRP_target). Based on the RSRP_target, the array gain of the transmitter can be derived, and based on this, the antenna array selection and beam design are performed, and the network deployment and planning are completed. Generally, RSRP_target=Tx_power+Tx_ant_array_gain-PL_target, where Tx_power is the transmit power of the antenna array, Tx_ant_array_gain is the current array gain or the array gain that can be obtained through the current beam, and PL_target is the path loss that can be accepted or allowed by the network design or planning Or the maximum path loss, PL_target is determined by the coverage distance, frequency band and environment required by the open environment. When Tx_power and PL_target are determined, the array gain of the antenna array can be determined. Currently, when deploying and planning the network according to the coverage required by this open environment, if the actual scenes are mostly multiple partition scenes, over-coverage problems may occur. When all the scenes use the same beam, it will cause damage to neighboring areas. Great interference.

Based on the foregoing problems, the embodiments of the present application provide a beam adjustment method. After network deployment, the network device can determine the allowable adjustment amount for downlink signal transmission by testing the first RSRP of one or more beams, and compare the adjustment amount based on the adjustment amount. The transmit power and/or array gain of the beam are adjusted to solve the problem of neighboring cell interference caused by the fixed beam design.

FIG. 2 is a schematic diagram of an embodiment of a beam adjustment method provided by an embodiment of the application.

Referring to FIG. 2, an embodiment of the beam adjustment method provided by the embodiment of the present application includes:

201. The network device determines the first RSRP according to the minimum value of the reference signal received power RSRP corresponding to each beam in one or more beams.

The one or more beams in the embodiment of the present application may refer to one or more beams among all the beams corresponding to the network device. In the embodiment of this application, the minimum value of the RSRP corresponding to each beam in one or more beams may be the uplink reference signal (sounding reference signal, SRS) corresponding to each beam in the one or more beams. Measurement, or receiving measurement report information (for example, physical layer L1-RSRP) of the one or more beams by the terminal device. Since the distance between the terminal equipment and the network equipment within the coverage of the same beam may be different, the minimum RSRP corresponding to a beam may correspond to the RSRP of the terminal equipment furthest from the network equipment within the coverage of the beam, or It is the minimum value of RSRP corresponding to the beam reported by multiple terminals. In the embodiments of this application, the beam information sent by the network device is not visible to the terminal device, and the terminal device can identify the pilot resource sent through the beam. Generally, different beams correspond to different pilot resources, or beams and pilot resources one by one. Correspondingly, when performing channel test feedback, the pilot resource identifier and the corresponding RSRP can be carried in the RSRP test report information. For example, the resource identifier can be a synchronization signal block (synchronization signal block, SSB) index, a downlink reference signal (channel state information reference signal, CSI-RS) index or CSI-RS resource index. The network device can associate the beam used when the resource is sent according to the resource identification, so that the RSRP of different beams can be distinguished.

In the embodiment of the present application, the network device may only obtain the minimum value of the RSRP corresponding to one beam. For example, the minimum value of the RSRP corresponding to the one beam is 12 dB. In the embodiment of the present application, the network device may also obtain the minimum value of RSRP corresponding to each of the multiple beams. For example, the minimum value of RSRP corresponding to beam 1 is 12 dB, and the minimum value of RSRP corresponding to beam 2 is 15 dB. The minimum RSRP corresponding to beam 3 is 18dB. After obtaining the minimum value of the RSRP corresponding to each beam in the one or more beams, the network device determines the first RSRP according to the minimum value of the one or more RSRP.

In the embodiment of the present application, when the network device only obtains the minimum RSRP corresponding to one beam, the first RSRP is the minimum RSRP. Optionally, when the network device obtains the minimum value of the RSRP corresponding to each beam in the multiple beams, the first RSRP in the embodiment of the present application may be the minimum value of the multiple RSRP corresponding to the one or more beams. RSRP. For example, when multiple beams are beam 1, beam 2, and beam 3, the minimum value of RSRP corresponding to beam 1 is 12 dB, the minimum value of RSRP corresponding to beam 2 is 15 dB, and the minimum value of RSRP corresponding to beam 3 is 18 dB. At this time, the first RSRP is 12 dB corresponding to beam 1. Optionally, when the network device obtains the minimum value of the RSRP corresponding to each beam in the multiple beams, the first RSRP in the embodiment of the present application may be the average of the minimum values of the multiple RSRP corresponding to the one or more beams. value. For example, when multiple beams are beam 1, beam 2, and beam 3, the minimum value of RSRP corresponding to beam 1 is 12 dB, the minimum value of RSRP corresponding to beam 2 is 15 dB, and the minimum value of RSRP corresponding to beam 3 is 18 dB. At this time, the first RSRP is 15dB.

202. The network device determines the adjustment amount according to the first RSRP and the second RSRP, where the second RSRP is a preset parameter.

In the embodiment of the present application, after obtaining the first RSRP obtained by actual measurement, the network device determines the adjustment amount allowed by the network device when transmitting the downlink signal according to the first RSRP and the second RSRP. The second RSRP in the embodiment of the present application is a preset parameter. That is, the second RSRP in the embodiment of the present application may be a preset parameter. For example, the modulation and coding method of the edge may be determined based on the edge rate, the required SINR is determined according to the modulation and coding method, and finally the second RSRP (eg, SINR*noise floor=second RSRP) is determined.

Optionally, the second RSRP in the embodiment of the present application may be determined according to the first transmission power and the first array gain. The first transmit power is the transmit power of the antenna array with one or more beams currently configured, and the first array gain is the array gain of the antenna array with one or more beams currently configured or an array that can be obtained by the current one or more beams Gain. For example, the second RSRP=first transmit power+first array gain-target path loss, where the target path loss may be the maximum path loss that can be received during network design or planning or the maximum allowable path loss. It should be noted that the second RSRP in the embodiment of the present application may also be determined in other ways, which is not limited in the embodiment of the present application.

The adjustment amount in the embodiment of the present application is used to adjust the first transmission power and/or the first array gain of the antenna array.

Optionally, the adjustment amount in the embodiment of the present application=first RSRP-second RSRP.

Optionally, in order to make the adjustment more robust, a margin can also be introduced, and the margin is related to the difference in the receiving capability of the receiving end. That is: the adjustment amount = the first RSRP-the second RSRP-the margin. Since the receiving capabilities of the receiving end may be different, the margin may be "maximum receiving antenna gain-minimum receiving antenna gain".

203. The network device adjusts the first transmit power and/or the first array gain of the currently configured one or more beams according to the adjustment amount.

In the embodiment of the present application, after determining the adjustment amount according to the first RSRP and the second RSRP, the network device adjusts the first transmission power and/or the first array gain of the antenna array currently configured for one or more beams according to the adjustment amount .

In the embodiments of the present application, when the first RSRP is greater than the second RSRP, it means over coverage. Therefore, the first transmit power and/or first array gain currently configured for one or more beams can be adjusted to reduce the current The configured first transmit power and/or first array gain reduces the coverage area and reduces interference to neighboring cells.

There are three adjustment methods in the embodiment of this application, namely: the network device adjusts the first transmission power according to the adjustment amount; the network device adjusts the gain of the first array according to the adjustment amount; the network device adjusts the first transmission power and the first transmission power at the same time. Array gain. When the network device adjusts the gain of the first array, it mainly adjusts the gain of the array by broadening the beam, cutting the beam, or adjusting the beam direction, that is, adjusting the beam weight. You can specify in advance which adjustment method the network device uses to adjust. It is understandable that adjustment methods can also be screened through actual adjustment requirements. For example, when the adjustment amount exceeds the power adjustment range or the single adjustment range such as beam broadening, the method of simultaneously adjusting the first transmission power and the first array gain can be selected. Optionally, when adjusting the first transmission power and the first array gain at the same time, different adjustment granularities can be used. For example, coarse-grained adjustment (such as 3dB granularity) can be implemented through beam broadening, and fine-grained adjustment (such as 1dB or 0.1dB, etc.) can be implemented through transmit power adjustment.

In the embodiment of the present application, after network deployment, the network device can determine the allowable adjustment amount during downlink signal transmission by testing the first RSRP of one or more beams, and perform the transmission power and/array gain of the beam based on the adjustment amount. Adjust to solve the neighbor interference problem caused by the fixed beam design.

Optionally, based on the embodiment of FIG. 2, when the network device does not change the first transmission power after determining the adjustment amount according to the first RSRP and the second RSRP, but chooses to adjust the gain of the first array, it can adjust The adjustment of the gain of the first array is realized by means of beam weight or beam broadening. Please refer to FIG. 3, which is a schematic diagram of an embodiment in which a network device adjusts the gain of the first array according to an adjustment amount provided in an embodiment of the present application.

Fig. 3 is a schematic diagram of an embodiment in which a network device adjusts the gain of the first array according to an adjustment amount according to an embodiment of the application, including:

2031. The network device determines the second array gain according to the adjustment amount and the first array gain.

In the embodiment of the present application, after the network device determines the adjustment amount according to the first RSRP and the second RSRP and chooses to adjust the first array gain, the network device first determines the second array gain according to the adjustment amount and the first array gain. The array gain is a new array gain that satisfies the network coverage. When the first RSRP is greater than the second RSRP, it indicates that the network has deployed coverage. At this time, the second array gain = the first array gain-the adjustment amount.

2032. The network device determines the target beam weight according to the second array gain.

In the embodiment of the present application, after determining the second array gain according to the adjustment amount and the first array gain, the network device determines the target beam weight according to the second array gain, and the target weight is a new beam weight that satisfies the second array gain. value.

Optionally, in this embodiment of the present application, the network device may determine the target beam weight by online generation, for example, a discrete Fourier transform (DFT) weight may be used.

Specifically, the method for the network device to determine the target beam weight by online generation may be: the network device first determines the target number N of new antenna elements according to the second array gain G, for example, root G=10*log(N) dB calculates the value of the target number N. When there are K beams, given the beam number K, a new beam weight can be obtained according to the following formula, and the new beam weight is the target beam weight:

Among them, n _i is the antenna element, i=0,1,2,...N-1.

Optionally, in this embodiment of the application, the network device may also pre-generate and store weights that satisfy various array gains. After the network device determines the second array gain according to the adjustment amount and the first array gain, the network device determines the second array gain according to the second array gain. The gain directly or indirectly obtains the pre-stored beam weights. details as follows:

a. There is a correlation between the array gain and the beam weight.

After determining the second array gain, the network device directly determines the beam weight corresponding to the second array gain according to the association relationship.

b. There is an association between the number of antenna elements and the beam weight.

After the network device determines the second array gain, it first determines the target number of antenna elements according to the second array gain. For example, the target number of antenna elements corresponding to the second array gain can be calculated according to the array gain G=10*log(N)dB. Then, the target beam weight is obtained according to the target number of the antenna elements and the correlation relationship.

c. There is an association between beam width and beam weight.

After determining the second array gain, the network device first determines the beam width according to the second array gain. For example, according to the formula array gain G=10*log(32000/(3dB horizontal wave width*3dB vertical wave width)) dB, determine the beam width corresponding to the second array gain, and then determine the target beam according to the beam width and the correlation relationship Weight.

2033. The network device configures the beam weight of the antenna array to be the target beam weight, so that the array gain of one or more beams meets the second array gain.

In the embodiment of the present application, after determining the target beam weight corresponding to the second array gain, the network device performs the configuration of the target beam weight.

It should be noted that the network device in the embodiment of the present application includes a baseband module and a radio frequency module of an antenna array, and the radio frequency module of the antenna array may be an intermediate radio frequency module or an active antenna unit (AAU).

Optionally, in the embodiment of the present application, the baseband module may determine the second array gain, and determine the target beam weight by online generation or pre-stored according to the second array gain, and finally configure the target beam weight to the radio frequency Module.

Optionally, in the embodiment of the present application, the baseband module may determine the second array gain, or the target number of antenna elements corresponding to the second array gain, or the beam width corresponding to the second array gain, and then the baseband module The above information is sent to the radio frequency module, and the radio frequency module obtains the target beam weight by online generation or pre-stored method, and configures the target beam weight.
