The donor base station is a form of a radio station, and refers to a radio transceiver station that performs information transfer with a UE through a mobile communication switching center in a certain radio coverage area. The relay device can regenerate and amplify signals, often serving as a relay node of the donor base station, so as to forward and amplify signals from the donor base station or the UE, thereby expanding the coverage area of the cell.

However, when the relay device accesses the donor base station, a certain noise is introduced into the donor base station, so that the equivalent thermal noise level of the donor base station is increased, and the sensitivity of the receiver of the donor base station is reduced to different degrees, thereby affecting the uplink coverage of the donor base station.

Taking NCR (Network Controlled Repeater) as a relay device as an example, the effect of access of the relay device on the uplink coverage of the donor base station is described as follows:

When the NCR accesses the donor base station, the thermal noise level of the donor base station is converted from the original actual thermal noise level of the donor base station to the equivalent thermal noise level of the donor base station, and the equivalent thermal noise level can be determined by the following formula:

Equivalent thermal noise level=10×lg (KTB) +nf+g-PL

Wherein 10×lg (KTB) is the actual thermal noise level of the base station, NF is the noise figure of NCR, G is the amplification factor of NCR, and PL is the signal attenuation in the signal transmission process from NCR to the donor base station.

From the above equation, the NCR access will raise the thermal noise level of the donor base station by (nf+g-PL) dB, so that the receiver of the donor base station will have a reduced sensitivity, thereby affecting the uplink coverage of the donor base station.

In order to solve the above-mentioned problems in the related art, the present application proposes to control the change of the thermal noise level of the donor base station caused by the access of the relay device by reasonably changing the beam gain of the relay device and/or the beam gain of the donor base station after the access of the relay device, so as to reduce the influence of the access of the relay device on the uplink coverage area of the donor base station. The beam gain setting method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

In a first aspect, a flowchart of a beam gain setting method according to an embodiment of the present application may include at least one of:

A-1: the relay device receives indication information of a first beam gain sent by the network side device, and sets the beam gain according to the indication information of the first beam gain, wherein the indication information of the first beam gain is used for indicating the relay device to set or adjust the beam gain.

A-2: the relay device sends a beam training request to the network side device, and sets a beam gain by setting a receiving beam or a sending beam of a beam training reference signal, wherein the beam training request is used for requesting the network side device to schedule the beam training reference signal.

A-3: the relay device sends a second beam gain adjustment request to the network side device, where the second beam gain adjustment request is used to request the network side device to adjust the beam gain.

The relay device may be relevant devices such as NCR, RIS (Reconfigurable Intelligence Surface, intelligent super surface) and the like, which can be used as a relay node between the access network device and the UE, the UE may be the terminal device 11 in fig. 1, the network side device may be the access network device in fig. 1, such as a host base station or an artificial intelligence processing node newly defined at the access network side, and may also be the core network device in fig. 1, which should have a scheduling capability for relevant resources and functions of the access network device, and examples of the terminal device, the access network device and the core network device may be referred to above, which will not be repeated herein.

For item a-1, the indication information of the first beam gain is used for indicating the relay device to set or adjust the beam gain of the transmission beam of the uplink signal. For example, the instruction information of the first beam gain may instruct the relay device to set the beam gain of the transmission beam WB1 of the uplink signal to K1 (dB), or instruct the relay device to decrease the original beam gain of the transmission beam WB1 by K2 (dB), and the relay device may set a specific value of the beam gain of the transmission beam WB1 according to the received instruction information of the first beam gain. For another example, assuming that there is channel reciprocity of the channel from the base station to the relay device, the relay device determines the uplink beam through the downlink beam training procedure (i.e., the indication information of the first beam gain may instruct the relay device to set or adjust the beam gain of the reception beam of the downlink signal, so as to set the beam gain of the transmission beam of the uplink signal). For example, when the relay device receives the indication information of the first beam gain including the downlink beam indication and/or the gain adjustment indication, the relay device changes the gain of the downlink receiving beam, and uses the changed downlink receiving beam as the uplink transmitting beam, so as to change the gain of the uplink transmitting beam, and for example, for the case that the relay device determines the uplink transmitting beam through the uplink beam training process, the base station sends the indication information to the relay device to indicate the adjustment information of the uplink transmitting beam of the relay device (i.e. the indication information of the first beam gain directly indicates the relay device to adjust the beam gain of the transmitting beam of the uplink signal, and when the relay device performs the beam training again, the gain of the uplink transmitting beam is changed.

Aiming at the item A-2, the relay equipment requests the base station to schedule uplink reference signal transmission resources or transmit downlink beam training reference signals so as to be capable of carrying out beam training again and further finding out a proper uplink beam, and larger interference caused to base station reception is avoided. And the relay equipment performs new round of beam training on the receiving beam or the transmitting beam of the beam training reference signal according to the beam training reference signal scheduled by the network side equipment. For example, the relay device performs a round of training adjustment on the transmission beam WB1 of the uplink signal according to the uplink beam training reference signal, if the beam gain of the transmission beam WB1 after the round of training adjustment does not reach the set requirement (for example, the beam gain does not reach K1 (dB)), the relay device sends a beam training request to request the base station to schedule the uplink reference signal transmission resource again (i.e., request the network side device to schedule the uplink beam training reference signal again), and the relay device performs a new round of beam training on the transmission beam WB1 according to the rescheduled uplink beam training reference signal until the beam gain of the transmission beam WB1 reaches the set requirement, thereby implementing the beam gain setting on the transmission beam; or based on the reciprocity of the channel, the relay device sends the downlink beam training reference signal through the multi-time request base station to perform multi-round training adjustment on the received beam WB2 of the downlink signal until the received beam WB2 with the beam gain of K1 (dB) is obtained, and then the received beam WB2 is used as the transmitted beam WB1' of the uplink signal, so that the beam gain setting of the transmitted beam is realized.

And aiming at the item A-3, the indication information of the second beam gain is used for indicating the network side equipment to adjust the beam gain of the receiving beam of the uplink signal. For example, the second beam gain instruction information may request the network side device to set the beam gain of the reception beam WB3 of the uplink signal to K1 (dB), or may request the network side device to reduce the original beam gain of the reception beam WB3 by K2 (dB), so that the network side device sets a specific value of the beam gain of the reception beam WB3 according to the received second beam gain instruction information.

In the implementation, the relay device executes at least one of the items a-1 to a-3, and realizes setting of the beam gain through interaction with the network side device, so that the change of the thermal noise level of the network side device is controlled through setting of the beam gain, and further the influence of access of the relay device on the uplink coverage area is reduced.

Taking NCR as a relay device as an example, the implementation principle of controlling the change of the thermal noise level of the network device by setting the beam gain through the interaction between the relay device and the network device will be described:

Fig. 2 is a schematic diagram of a signal amplifier network, which includes a BS (Base Station), NCR and UE. The upstream base station (i.e., donor base station) may control transmission parameters of the NCR, such as the receive/transmit beam between the NCR and the base station or between the NCR and the UE, etc. The NCR includes an MT (mobile termination, terminal module) and an Fwd unit (forwarding unit). Wherein, the MT can establish a connection with an upstream base station through a control link, and the BS can control transmission/reception related parameters (such as parameters of power, amplification factor, beam, on/off of signal transmission, etc.) of a backhaul link between the NCR and the base station or ACCESS LINK (access link) between the NCR and the UE by transmitting control signaling to the MT in the NCR.

The access of the NCR will raise the thermal noise level of the BS (NF+G-PL) dB, at which time if the signal attenuation from the NCR to the BS is too small, the thermal noise level of the BS will rise substantially, so that the uplink coverage of the BS is reduced. Considering that the noise figure NF and the amplification factor G of the NCR can be generally regarded as fixed parameters that do not change, the signal attenuation PL of the NCR to the BS can be increased to maintain or increase the uplink coverage of the BS at the time of the access of the NCR. The signal attenuation PL is mainly determined by path loss and beam gain, so the application is based on a control link between the MT and an upstream base station, and can control the signal attenuation PL between the BS and the NCR by setting the beam gain (for example, increasing the signal attenuation PL by reducing the beam gain) under the condition of unchanged amplification factor G so as to reduce the thermal noise level of the BS, thereby being capable of maintaining or increasing the uplink coverage of the BS during the NCR access, and further reducing the influence of the NCR access on the uplink coverage.

As can be seen from the above steps, in the embodiment of the present application, the network side device instructs the relay device to change its own beam gain by sending the first beam gain instruction information to the relay device, or the relay device sends the beam training request to the network side device, according to the scheduling of the beam training reference signal by the network side device, changes the own beam gain of the relay device, or the relay device sends the second beam gain adjustment request to the network side device, instructs the network side device to change its own beam gain, so that based on the interaction between the relay device and the network side device, the beam gain of the relay device and/or the beam gain of the network side device are controllably changed, so as to control the change of the thermal noise level of the donor base station caused by the access of the relay device by reasonably changing the beam gain, thereby reducing the influence of the access of the relay device on the uplink coverage of the donor base station.

Embodiment one

The present embodiment describes a case where the relay device receives the indication information of the first beam gain transmitted by the network side device. An embodiment one will be described below with reference to fig. 3. As shown in fig. 3, the interaction between the relay device and the network side device includes the following steps:

Step S301: the network side equipment sends indication information of the first beam gain to the relay equipment.

In the implementation, the network side device measures the uplink interference/noise intensity caused by the relay device after the relay device is accessed or started, and if the interference/noise intensity is larger, the network side device can instruct the relay device to reduce the beam forming gain (namely the beam gain) of the sending beam by sending the indication information of the first beam gain, so that the uplink interference/noise intensity caused by the relay device after the relay device is accessed or started is reduced, and the influence of the relay device access or the relay device on the uplink coverage area is reduced.

Step S302: the relay equipment receives the indication information of the first beam gain sent by the network side equipment, and sets the beam gain according to the indication information of the first beam gain.

Wherein the indication information of the first beam gain includes at least one of:

B-1: indication information of a transmission beam, the indication information of the transmission beam being used for indicating an attribute of the transmission beam used by the relay device, the attribute including at least one of: beam identification, beam direction, beam width;

B-2: adjustment indication information of a first beam gain, wherein the adjustment indication information of the first beam gain is used for indicating the relay equipment to reduce the beam gain of a transmitting beam;

b-3: and the indication information of the first beam gain is used for indicating the relay equipment to set the beam gain of the sending beam.

For the B-1 term, the beam identification indicates the beam that needs to be used by the transmit beam of the relay device, and it is understood that different beams have different beam properties, so the beam gain of the transmit beam can be correspondingly changed by changing the beam that needs to be used by the transmit beam.

For item B-2, the adjustment indication information of the first beam gain is used to inform the relay device that the beam gain of the current transmission beam is too high, and the relay device needs to reduce the beam gain of its own transmission beam, which may carry a change value (e.g. increase or decrease by 5 dB) compared with the current beam gain. After receiving the adjustment instruction information of the first beam gain, the relay device can correspondingly adjust the beam gain of the relay device.

As a possible implementation manner, after receiving the adjustment instruction information of the first beam gain, the relay device sets the beam gain of the transmitting beam according to whether the parameter value generated by the transmitting uplink signal is not higher than or lower than the threshold value pre-negotiated with the network side device. The threshold value is used for indicating the threshold of the rise of the thermal noise level, so that the rise of the thermal noise level is prevented from being too large, and the uplink coverage area is reduced sharply.

For item B-3, the indication information of the first beam gain is used to inform the relay device how much beam gain of the transmit beam needs to be set, which may carry a specific value (e.g., 5 dB) of the required beam gain.

Second embodiment

The present embodiment describes a case where the relay device sends a beam training request to the network side device. The second embodiment will be described below with reference to fig. 4. As shown in fig. 4, the interaction between the relay device and the network side device includes the following steps:

Step S401: and the relay equipment sends a beam training request to the network equipment.

The relay device may send a beam training request to the network side device after receiving the indication information of the first beam gain from the network side device, or after determining that the access of the relay device may cause greater interference/noise to the reception of the network side device, so as to change the beam gain.

Step S402: and the network side equipment receives the beam training request sent by the relay equipment and schedules a beam training reference signal according to the beam training request.

Wherein the beam training request comprises: a request for requesting the network side device to send a downlink beam training reference signal; or a request for requesting the network side device to schedule the relay device to send an uplink beam training reference signal.

Step S403: the relay device sets a beam gain by setting a reception beam or a transmission beam of the beam training reference signal.

For the case of a request for requesting the network side device to send a downlink beam training reference signal, the network side device sends a multi-round downlink beam training reference signal to the relay device, so that the relay device performs multi-round training on a receiving beam of the downlink beam training reference signal until the beam gain of the receiving beam meets a setting requirement (for example, the rising amount of the generated thermal noise level is not higher than a threshold value or accords with a specific value of the beam gain indicated by the network side device, etc.), then the relay device uses the receiving beam to send an uplink signal (i.e. uses the receiving beam as a sending beam), thereby determining the situation of the uplink beam through the downlink beam training, and further realizing setting of the beam gain of the sending beam, where the downlink beam training reference signal may be CSI-RS (CHANNEL STATE Information-REFERENCE SIGNAL, channel state Information reference signal).

Aiming at the situation that the network side equipment requests to schedule the relay equipment to send the uplink beam training reference signal, the relay equipment requests the network side equipment to schedule corresponding resources so as to support the relay equipment to send multiple rounds of uplink beam training reference signals to the network side equipment, and the relay equipment performs multiple rounds of training on the sending beam of the uplink beam training reference signals so as to set the beam gain of the sending beam, wherein the uplink beam training reference signals can be SRS (Sounding REFERENCE SIGNAL, channel Sounding reference signals).

As a possible implementation manner, the relay device sets a beam gain, including:

The relay device sets a parameter value of a parameter related to a beam gain of a transmission beam;

Wherein the parameters related to the beam gain of the transmit beam include at least one of:

beam gain;

a beam width;

A beam direction;

a beam hierarchy;

the beam type;

Beam coverage.

In the implementation, the controllable change of the beam gain can be directly realized by setting the specific value of the beam gain of the transmission beam, or can be indirectly realized by setting the specific value of other parameters related to the beam gain of the transmission beam. For example, the beam gain may be indirectly changed by changing the beam width (the narrower the beam, the greater the beam gain), or the beam may be divided into multiple levels according to the beam width or gain, the beam gain may be indirectly changed by selecting beams of different beam levels, or the beam gain may be indirectly changed by changing the beam direction (the smaller the beam normal direction deviates from the direction in which the counterpart device is located), or the beam gain may be indirectly changed by changing the beam type (one specific value/range value of the beam corresponds to the beam gain, or one type of the beam corresponds to one beam width, or one range of the beam corresponds to one beam width, etc.), or the beam gain may be indirectly changed by changing the beam coverage (the smaller the beam coverage, the greater the beam gain). Thus, setting of the beam gain is achieved by setting the parameter value of the parameter related to the beam gain of the transmission beam.

Embodiment III

The present embodiment describes a case where the relay device transmits a request for adjusting the second beam gain to the network side device. The third embodiment will be described below with reference to fig. 5. As shown in fig. 5, the interaction between the relay device and the network side device includes the following steps:

step S501: the relay equipment sends a second beam gain adjustment request to the network equipment;

Step S502: and the network side equipment receives the second beam gain adjustment request sent by the relay equipment and adjusts the beam gain according to the second beam gain adjustment request.

In the implementation, when the relay device cannot effectively control the uplink coverage area by setting the own beam gain, for example, when the relay device cannot obtain a transmitting beam meeting the setting requirement through beam training, the relay device can request the network side device to change the own beam gain, at this time, the relay device does not need to change the beam gain of the own transmitting beam, and the network side device adjusts the beam gain of the own receiving beam, so that the network side device adjusts the beam gain of the receiving beam, changes the signal attenuation PL, and further controls the change of the thermal noise level caused by the access of the relay device. The interaction process of the relay device requesting the network side device to adjust the beam gain of the relay device is similar to the interaction process of the network side device instructing the relay device to change the beam gain of the relay device, and will not be repeated here.

In a second aspect, an embodiment of the present application provides another beam gain setting method, which includes at least one of the following:
