The following description is presented to enable one skilled in the art to better understand the embodiments of the present application.

Base station control amplifier (Network Controlled Repeater, NCR):

the NCR node is also called a smart repeater (smart repeater). The NCR node is used for expanding the coverage of a cell and comprises the steps of receiving and amplifying downlink signals from an upstream base station, so that the signal strength reaching UE is increased; the uplink signal from the UE is amplified such that the strength of the uplink signal from the UE to the upstream base station increases.

The NCR node may receive control from an upstream base station, i.e., the base station may control the transmit parameters of the smart amplifier, such as the switching of the NCR node and the transmit beam, to improve the efficiency of the amplifier and reduce interference. In the network structure shown in fig. 2, which comprises 3 network nodes, the intermediate network node is a forwarding device, such as an NCR node, which comprises a terminal module (Mobile Termination, MT) and a relay module (RU, or forwarding module), and the signal amplifier is not excluded from comprising only one of the MT or RU. Wherein the MT can establish a connection with an upstream base station, and the base station can instruct the transmission/reception related parameters of the MT/RU of the signal amplifier through the MT and the signal amplifier interaction control signaling.

The operating principle of NCR nodes:

for downlink transmission, the NCR node forwards signals sent by the base station to the UE, and the forwarding process comprises the steps of receiving signals from the base station, amplifying the signals and sending the signals to the UE; for uplink transmission, the NCR node forwards the signal sent by the UE to the base station, and the forwarding process includes receiving the signal from the UE, amplifying the signal, and sending the signal to the base station.

When the NCR node forwards signals, the receiving antenna provides receiving gain, the transmitting antenna provides transmitting gain and the power amplifier provides amplification gain of the forwarded signals. Through uplink signal forwarding, the signal received by the base station from the UE is enhanced, so that interference can be better resisted.

RAN system uplink scheduling principle:

the uplink scheduling of the current RAN may be performed based on the uplink pending data amount of the UE, the reported available power headroom of the UE (i.e., the power headroom value indicated by the power headroom report (Power Headroom Report, PHR)) and some other optional information, such as an uplink power control command sent to the UE after the last time the PHR reported by the UE was received. The larger the uplink waiting data volume of the UE and the larger the available power allowance of the UE, the larger the uplink transmission data block of the UE which can be scheduled by the base station, namely the base station can schedule higher MCS and more frequency resources for the UE. According to current power control algorithms, the uplink transmit power of a UE is determined jointly by the UE to base station propagation loss, base station target received power, modulation and coding scheme (Modulation and coding scheme, MCS), frequency resources and received power control commands. If the MCS corresponding to the uplink scheduling transmission of the base station is too high and/or the frequency resource is too wide, the required uplink transmission power exceeds the maximum uplink transmission power of the UE, so that the uplink transmission requirement cannot be met.

The uplink power headroom of the UE is defined as a ratio of the maximum transmission power or the remaining transmission power of the UE to the current actual transmission power.

The information transmission 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.

As shown in fig. 3, an embodiment of the present application provides an information transmission method, including:

step 301: the forwarding device sends first information to the network side device, wherein the first information comprises at least one of forwarding power allowance and actual forwarding power of the forwarding device, and the forwarding device is used for forwarding information interacted between the network side device and the terminal.

Optionally, the information interacted by the network side device and the terminal includes at least one of an air interface synchronization signal, configuration signaling and quantity.

Optionally, the forwarding device is a base station control amplifier (Network Controlled Repeater, NCR).

The actual forwarding power is the forwarding power used when the forwarding device forwards the data interacted by the network side device and the terminal.

It should be noted that, the forwarding power headroom of the forwarding device may also be described as a forwarding power headroom or a transmission power headroom of a forwarding module in the forwarding device, such as a forwarding power headroom or a transmission power headroom of an RU in the NCR. The above-described forwarding power headroom of the forwarding device may also be described as a transmit power headroom of the forwarding device. The actual forwarding power of the forwarding device specifically refers to the actual forwarding power of the forwarding module or the actual transmitting power of the forwarding module in the forwarding device.

In the embodiment of the application, the forwarding device sends the first information to the network side device, so that the network side device determines the forwarding power allowance of the forwarding device according to the first information, so that the network side device can schedule the terminal based on the forwarding power allowance of the forwarding device and the power allowance of the terminal, thereby ensuring that the forwarding power of the forwarding device can meet the forwarding power of the scheduled uplink transmission, ensuring that the uplink transmission signal strength actually reaching the network side device meets the corresponding requirement, further reducing the error rate of the uplink transmission of the UE, and improving the reliability of the uplink transmission.

Optionally, before the forwarding device sends the first information to the network side device, the forwarding device further includes:

the forwarding device determines the forwarding power margin according to the ratio of the maximum forwarding power to the actual forwarding power of the forwarding device or the ratio of the residual forwarding power to the actual forwarding power of the forwarding device;

or the forwarding device determines the forwarding power margin according to the ratio of the maximum forwarding power of the forwarding device to the actual total transmission power or the ratio of the residual forwarding power of the forwarding device to the actual total transmission power;

Wherein the remaining forwarding power is determined according to a difference between the maximum forwarding power of the forwarding device and an actual forwarding power or an actual total transmission power.

The maximum forwarding power may be configured by the network side device or may be agreed by a protocol. In a specific embodiment of the present application, the forwarding power headroom is determined by at least one of the following formulas:

PH(dB)＝Pmax-repeat(dBm)-Prepeat(dBm)；

PH(dB)＝Prest-repeat(dBm)-Prepeat(dBm)；

wherein PH represents the forward power margin, pmax-repeat represents the maximum forward power, prerepeat represents the actual forward power, and Prest-repeat represents the remaining forward power. The remaining forwarding power = maximum forwarding power-actual forwarding power.

Optionally, the forwarding device includes a terminal module and a forwarding module, and optionally, the forwarding module may be specifically an RU;

the actual total transmission power of the forwarding device is determined based on the actual transmission power of the terminal module and the actual forwarding power of the forwarding module.

Optionally, in the case that the uplink transmission of the terminal module and the forwarding transmission of the forwarding module are performed in a frequency division multiplexing manner, the forwarding device determines the forwarding power margin according to a ratio of a maximum forwarding power of the forwarding device to an actual total transmission power, or according to a ratio of a remaining forwarding power of the forwarding device to the actual total transmission power.

Specifically, the forwarding power headroom is determined by at least one of the following formulas:

PH(dB)＝Pmax-repeat(dBm)-10Xlog10(Prepeat(mW)+P _MT (mW))；

PH(dB)＝Prest-repeat(dBm)-10Xlog10(Prepeat(mW)+P _MT (mW))；

wherein PH represents the forwarding power margin, pmax-repeat represents the maximum forwarding power, repeat represents the actual forwarding power of the forwarding module, and P _MT Representing the actual transmit power of the terminal module, prest-repeat represents the remaining forward powerThe rate. The remaining forwarding power = maximum forwarding power-actual total forwarding power.

In a specific embodiment of the present application, please refer to fig. 4, which illustrates a case that the power headroom of the terminal is greater than the forwarding power headroom of the forwarding device, the base station may determine the dynamic range of the signal strength of the UE reaching the base station based on the power headroom of the terminal and the forwarding power headroom of the forwarding device, so as to avoid that the forwarding power of the required forwarding device exceeds the maximum forwarding power of the forwarding device in the scheduling process of the UE.

Optionally, the forwarding device sends first information to a network side device, including:

for the same carrier, the forwarding device sends at least one uplink transmission corresponding first information to network side equipment;

the forwarding device comprises a terminal module and a forwarding module, and the primary uplink transmission comprises at least one of forwarding by the forwarding module and transmitting by the terminal module.

For example, for the same carrier, the forwarding device sends the first information corresponding to at least one time slot to the network side device, where the at least one time slot is a time slot corresponding to at least one uplink transmission.

Optionally, the forwarding device sends the first information corresponding to the uplink transmission at least once to a network side device, including:

the forwarding device sends a power headroom report, wherein the power headroom report comprises a time identifier corresponding to at least one uplink transmission and first information corresponding to each time identifier in the at least one uplink transmission.

Alternatively, the time identifier may be a slot number, and of course, may be a symbol number. The network side equipment can determine the uplink transmission corresponding to the first information through the time mark.

For example, the forwarding device sends a power headroom report to the network side device, where the power headroom report includes a slot number of the at least one slot and first information corresponding to each slot number.

Optionally, the forwarding device sends first information to a network side device, including one of the following:

(a) The forwarding device sends first information to network side equipment according to the sending period;

(b) The forwarding equipment sends first information to network side equipment according to the reporting instruction;

(c) And the forwarding equipment sends first information to the network side equipment under the condition that the triggering condition of the power headroom report is met.

For (a), the network side device may configure periodic power reporting to the forwarding device, and the network side device configures reporting period (transmission period) and time offset to the forwarding device. The time offset may be indicated by a radio frame/slot/symbol sequence number or an offset time relative to the beginning of a radio frame.

For (b), the network side device may instruct the forwarding device to report the first information in real time. Through the instant indication, the network side equipment can instruct the forwarding equipment to report once or a plurality of subsequent reports, and the forwarding equipment receives the indication and reports the first information.

Optionally, for (c), the triggering condition of the power headroom report includes at least one of:

a first item: the required forwarding power is greater than or equal to the maximum forwarding power of the forwarding device;

the second item: the difference between the required forwarding power and the maximum forwarding power is greater than or equal to a first difference threshold;

third item: the forwarding power of the forwarding device is greater than or equal to a first forwarding power threshold;

Fourth item: the forwarding power of the forwarding device is less than or equal to the second forwarding power threshold;

the fifth item: the ratio of the change in the forwarding power of the forwarding device exceeds a first ratio threshold.

The second item described above can be divided into two cases, case 1: the required forwarding power is larger than the maximum forwarding power of the forwarding device, and the difference between the required forwarding power and the maximum forwarding power is larger than a first difference threshold; case 2: the required forwarding power is less than the maximum forwarding power of the forwarding device and the difference between the required forwarding power and the maximum forwarding power is greater than a second difference threshold. The above case 1 may be regarded as a case where the forwarding power headroom of the forwarding device is smaller, where the forwarding device is triggered to send the first information to the network side device so that the network side device avoids that the required forwarding power exceeds the maximum forwarding power of the NCR node, and the above case 2 may be regarded as a case where the forwarding power headroom of the forwarding device is larger, where the forwarding device is triggered to send the first information to the network side device so that the network side device schedules a larger uplink transmission data block for the terminal through the NCR node. The first and third items may be regarded as triggering transmission of the first information when the transmission power margin of the transmission device is small, and the fourth item may be regarded as triggering transmission of the first information when the transmission power margin of the transmission device is large. The first information is triggered to be sent under the condition that the forwarding power margin of the forwarding device is large, so that the network side device can also determine whether an uplink signal of a terminal is forwarded through the NCR node, and further determine whether an uplink radio frequency signal forwarding service needs to be provided through the NCR node. In this way, the network side device can perform related control operations on the NCR node, for example, whether the uplink forwarding of the NCR node can be temporarily turned off, so as to save the power consumption of the NCR node.

For the fifth item, when the change proportion of the forwarding power of the forwarding device exceeds the first proportion threshold, that is, when the change of the forwarding power is large, the first information is timely reported to the network side device, so that the network side device can correspondingly adjust according to the first information.

the forwarding equipment sends first information through uplink control information, a media access control unit (MAC CE) or Radio Resource Control (RRC) signaling;

wherein, the uplink control information is carried by a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH.

Optionally, before the forwarding device sends the scheduling request to the network side device by using the preconfigured uplink scheduling request resource, the method further includes:

and the forwarding equipment receives configuration information of uplink scheduling request resources from network side equipment.

In the embodiment of the application, the MT has no uplink transmission permission in general cases because the terminal module in the forwarding equipment has no own service. Here, when the forwarding device has a first information reporting requirement and no available uplink transmission permission, the protocol may predefined a scheduling request corresponding to the first device reporting requirement of the forwarding device or the network side device may configure an uplink PUSCH resource used by the forwarding device to transmit the first information. Optionally, when the network side device does not configure the PUCCH resource corresponding to the scheduling request, the terminal module may request an uplink transmission grant for forwarding the first information with a certain PUCCH resource configured by the network side device.

In the embodiment of the application, the forwarding device sends the first information to the network side device, so that the network side device determines the forwarding power allowance of the forwarding device according to the first information, so that the network side device can schedule the terminal based on the forwarding power allowance of the forwarding device and the power allowance of the terminal, thereby ensuring that the forwarding power of the forwarding device can meet the forwarding power of the scheduled uplink transmission, ensuring that the uplink sending signal strength actually reaching the network side device meets the corresponding requirement, and further reducing the error rate of the uplink transmission of the UE.
