In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

Multi-user interference

The 5G NR system introduces two services: URLLC (Ultra Reliable Low Latency Communication) and Enhanced Mobile Broadband (eMBB). The characteristic of URLLC is to achieve ultra-high reliability (for example, 99.999%) transmission within an extreme delay (for example, 1 ms), and the characteristic of eMBB is that it is insensitive to delay, but the number of transmissions can be large. For the scenario where URLLC and eMBB coexist, in order to realize URLLC instant transmission, URLLC and eMBB may conflict, that is, URLLC occupies resources that have been allocated to eMBB. When URLLC and eMBB transmission conflict, URLLC and eMBB will interfere with each other, thereby affecting the demodulation performance of URLLC and eMBB. Retransmission can solve this impact, but it will increase the transmission delay of URLLC.

Figure 2 shows the problem of transmission conflict between upstream URLLC and eMBB. There are two main stream solutions: 1) Stop eMBB transmission to reduce the interference to URLLC. 2) Increase the URLLC transmission power, even if eMBB interference exists, it can ensure that the URLLC received signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) meets the demodulation requirements. The former eliminates the interference completely, but needs to increase the complexity of the terminal for eMBB. The latter guarantees the received SINR by increasing the useful signal power, and only requires URLLC to be enhanced.

Closed loop power control

NR Rel15 uses group common DCI (Group common DCI) (such as DCI format 2_2) and UE specific DCI (UE specific DCI) (such as DCI format 0_0/0_1) to indicate closed loop power adjustment. Among them, the closed-loop adjustment power includes the following two modes, mode 1) cumulative adjustment; mode 2) absolute value adjustment. For mode 1), if the terminal receives power adjustment information a at time n, it adjusts the uplink transmission power a db; if the terminal receives power adjustment information b at time n+x, it adjusts the uplink transmission power a+b db , And so on. For mode 2), if the terminal receives power adjustment information a at time n, it adjusts the uplink transmission power a db; if the terminal receives power adjustment information b at time n+x, it adjusts the uplink transmission power b db to And so on. The closed-loop power adjustment mode used by the terminal is configured by high-level signaling.

It can be seen from the above technical solutions that increasing the URLLC transmission power can ensure the received SINR by increasing the useful signal power, but it is necessary to ensure that the user pilots of the URLLC and eMBB are orthogonal. If the TPC mechanism is used directly, if the terminal is required to increase the transmission power of service data, the network sends TPC signaling indicating the power increase. After that, if the terminal is required to reduce the transmission power of the service data, the network sends the TPC signal indicating the power decrease. In this way, it can be ensured that the transmission power of service data is within the normal range and will not cause excessive interference to other service data. In this case, when URLLC and eMBB transmission conflict, at least two TPC signaling transmissions are required, and the signaling overhead is relatively large. To this end, the following technical solutions of the embodiments of the present application are proposed.

FIG. 3 is a schematic flow chart 1 of the power adjustment method provided by an embodiment of the application. As shown in FIG. 3, the power adjustment method includes the following steps:

Step 301: The terminal receives power control information.

In the embodiment of the present application, the terminal receives power control information sent by a network device, where the network device may be a base station, such as a gNB.

In an optional implementation manner of the present application, the power control information may be TPC signaling or an open-loop parameter (open-loop parameter). It should be noted that the specific implementation of the power control information is not limited to the above two types.

It should be noted that the "terminal reception" involved in the embodiments of the present application can also be replaced by "terminal analysis" or "terminal reception and analysis".

Step 302: The terminal determines the first power adjustment amount and the power adjustment timeliness corresponding to the first power adjustment amount based on the power control information.

In the embodiment of the present application, the power control information includes at least one power adjustment amount, and the terminal determines the first power adjustment amount to be used from the at least one power adjustment amount, and determines that the first power adjustment amount corresponds to Timeliness of power adjustment.

Further, optionally, the terminal adjusts the transmission power based on the first power adjustment amount; the terminal determines the duration of the adjusted transmission power based on the timeliness of the power adjustment. In the embodiment of the present application, the terminal adjusts the transmit power based on the first power adjustment amount, which can be adjusted by using any of the following models: mode 1) cumulative adjustment; mode 2) absolute value adjustment.

In the embodiment of the present application, the adjustment of the transmission power has timeliness (referred to as the timeliness of power adjustment), and the terminal determines the duration of the adjusted transmission power based on the timeliness of the power adjustment. Specifically, the power adjustment timeliness may be the first timeliness or the second timeliness. It should be noted that the first timeliness may also be referred to as long-term effectiveness, and the second timeliness may also be referred to as fixed time window effectiveness. The two types of timeliness are described below.

First timeliness (also called long-term effectiveness)

The duration of the adjusted transmission power corresponding to the first timeliness includes the time between the first start moment and the first end moment; the first end moment is the moment when the first event occurs.

Further, optionally, the first starting moment is the time when the terminal receives the power control information.

It should be noted that when the timeliness of the power adjustment is long-term effective, the start time of the transmit power adjustment is the time when the terminal receives (or detects) the power control information, and the transmit power adjustment The end time is not limited. Further, the end time of the transmission power adjustment is determined based on the moment when the first event occurs. In an example, the first event is that the terminal receives power control information again.

During specific implementation, after the terminal adjusts the transmission power from the first transmission power to the second transmission power based on the first power adjustment amount, the second transmission power is maintained unchanged until the power control information is received again.

Second timeliness (also known as fixed time window validity)

The duration of the adjusted transmission power corresponding to the second timeliness includes the time between the second start time and the second end time; the second start time is the start time of the first time window, and the first time window The second end time is the end time of the first time window.

Optionally, the length of the first time window is fixed.

In an optional implementation manner, the first time window includes at least one data transmission opportunity after the first time, and the first time is the time when the terminal receives (or detects) the power control information.

In another optional implementation manner, the first time window includes at least one time unit after the first time, and the first time is the time when the terminal receives (or detects) the power control information, The time unit is a symbol (symbol) or a time slot (slot).

In the embodiment of the present application, the length of the first time window is preset or configured by higher layer signaling.

In specific implementation, after the terminal adjusts the transmission power from the first transmission power to the second transmission power based on the first power adjustment amount, the second transmission power is maintained unchanged within the first time window, and the After the first time window ends, the transmission power is restored from the second transmission power to the first transmission power, and the first transmission power is maintained unchanged until the power control information is received again.

In the embodiment of the present application, the terminal may determine the power adjustment timeliness corresponding to the first power adjustment amount in any of the following ways:

● Manner 1: The terminal determines the timeliness of power adjustment corresponding to the first power adjustment amount based on the first threshold information.

Specifically, if the first power adjustment amount is less than or equal to the first threshold information, the terminal determines that the power adjustment timeliness corresponding to the first power adjustment amount is the first timeliness; if the first power adjustment If the power adjustment amount is greater than the first threshold information, the terminal determines that the power adjustment timeliness corresponding to the first power adjustment amount is the second timeliness.

In the embodiment of the present application, the first threshold information is preset or configured by higher layer signaling.

● Method 2: If the first power adjustment amount belongs to the first power adjustment amount set, the terminal determines that the power adjustment timeliness corresponding to the first power adjustment amount is the first timeliness; if the first power If the adjustment amount belongs to the second power adjustment amount set, the terminal determines that the power adjustment timeliness corresponding to the first power adjustment amount is the second timeliness.

Here, the first power adjustment amount set includes at least one power adjustment amount, and the power adjustment timeliness corresponding to each power adjustment amount in the first power adjustment amount set is the first timeliness; the second power adjustment The quantity set includes at least one power adjustment quantity, and the power adjustment timeliness corresponding to each power adjustment quantity in the second power adjustment quantity set is the second timeliness.

Further, optionally, the intersection of the first power adjustment set and the second power adjustment set is empty, that is, the first power adjustment set and the second power adjustment set have no intersection.

In the embodiment of the present application, at least one of the first power adjustment set and the second power adjustment set is preset or configured by higher layer signaling.

For example, a terminal receives high-layer signaling (such as RRC signaling) sent by a network device (such as a base station), the high-layer signaling carries first configuration information, and the first configuration information includes the first power adjustment set And/or the second power adjustment set.

Take another example: the terminal determines the first power adjustment set and/or the second power adjustment set according to the agreement.

It should be noted that the “pre-setting” involved in the embodiment of the present application can also be replaced by “agreement agreement”.

Optionally, the "transmission power" involved in the embodiment of the present application can also be replaced with "uplink transmit power" or "uplink power".

In the technical solution of the embodiment of the present application, when the transmission conflict between URLLC and eMBB occurs, one TPC signaling is used to adjust the transmission power of URLLC. The terminal adjusts the transmission power according to the power adjustment amount in the TPC signaling, and after the time limit is over , Adjust the transmission power back to the normal range by itself, reducing the signaling overhead. The technical solution of the embodiment of the present application improves the useful signal power of the service data by adjusting the transmission power of the service data, and ensures that the SINR of the service data meets the requirements of service data transmission.

FIG. 4 is a schematic diagram 2 of the flow of the power adjustment method provided by an embodiment of the application. As shown in FIG. 4, the power adjustment method includes the following steps:

Step 401: The terminal receives power control information, and obtains a first power adjustment amount from the power control information.

Step 402: The terminal determines the power adjustment timeliness corresponding to the first power adjustment amount, if it is the first timeliness, execute step 403, and if it is the second timeliness, execute step 404.

Here, the first timeliness is used to indicate that the timeliness of the transmission power adjustment is long-term effective. The second timeliness is used to indicate that the timeliness of the transmission power adjustment is effective in a fixed time window.

Step 403: The terminal adjusts the transmission power according to the first power adjustment amount, and the adjustment of the transmission power is effective for a long time until step 401 is executed again.

Step 404: The terminal adjusts the transmission power according to the first power adjustment amount, and the adjustment of the transmission power is effective in a fixed time window.

Step 405: The terminal judges whether the end time of the first time window is reached, if yes, execute step 406, if no, the adjustment of the transmission power remains unchanged.

Step 406: cancel the current transmission power adjustment until step 401 is executed again.

The following describes the technical solutions of the embodiments of the present application with specific application examples.

Example one

(1) The network device receives the uplink URLLC service transmission request, and determines the transmission resources allocated to the URLLC according to the data volume of the URLLC, the encoding rate that the terminal can currently use, and other information. If the transmission resource allocated for URLLC conflicts with the resource allocated for eMBB use, it is necessary to consider adjusting the power of URLLC.

Since the scheduling decision and scheduling information transmission of URLLC and eMBB are not synchronized, and URLLC is sensitive to delay, that is, there is not enough time to wait for the transmission of idle resources. Therefore, resource conflict between URLLC and eMBB is inevitable, as shown in Figure 5. It shows that the terminal 3 transmitting eMBB and the terminal 2 transmitting URLLC conflict.

(2) The network device transmits power control information to adjust the transmission power of the URLLC, so that the URLLC has a sufficient SINR during decoding to ensure the reliability of the URLLC.

If the network equipment predicts that the interference energy of terminal 3 is X dB (such as 3dB), the power control information instructs terminal 2 to increase the transmit power by X dB (such as 3dB), so that the SINR of terminal 2 remains unchanged, and its reliability meets expectations aims. In general, the network equipment will determine the power control information (that is, the power adjustment amount) according to the conflict situation, and send the power control information to the terminal.

(3) The terminal receives power control information, the power control information includes at least a power adjustment amount (increase or decrease), and the power control information is carried in the scheduling DCI for transmission, or can be carried in the TPC dedicated DCI for transmission.

The terminal receives the PDCCH according to the established PDCCH detection rule, and analyzes whether the current PDCCH contains the DCI sent to the terminal and the type of DCI.

The value range of the power adjustment in the power control information should include: 1) Long-term adjustment set A (ie, the first power adjustment set), which can be used for long-term effective power adjustment; 2) Fixed time window effective adjustment set B (that is, the second power adjustment set) can be used for effective power adjustment in a fixed time window. Among them, the long-term adjustment amount set A and the fixed time window effective adjustment amount set B are two independent sets without intersection.

(4) The terminal performs corresponding operations based on the power control information. For example, the transmission power is adjusted according to the power control information, and the power adjustment is effective for a long time or for a fixed time window. The service data is transmitted based on the power adjustment result.

The agreement stipulates the timeliness determination threshold TH _{p of the} power adjustment information, or stipulates a set of adjustment amounts used for power adjustment with different timeliness. Power adjustment is effective for a long time, which means that the transmission power is adjusted according to the current power control information, and the adjusted transmission power is maintained until the power control information is successfully parsed next time. The power adjustment fixed time window is effective, which means that the transmission power is adjusted according to the current power control information, and the adjusted transmission power is maintained within the agreed effective time window (that is, the first time window). After the effective time window, the transmission power returns to before the adjustment . The effective time window agreed here can be one or several data transmission opportunities after receiving the power control information, or it can be several symbols or time slots. In principle, it should at least include the conflict time between URLLC and eMBB.

For a specific example, the current terminal transmission power is (P ₁ +δ ₀ ), when the power adjustment amount δ ₁ indicated in the DCI, the cumulative power adjustment mode transmission power needs to be adjusted to (P ₁ +δ ₀ +δ ₁ ), absolute In the value power adjustment mode, the transmission power needs to be adjusted to (P ₁ +δ ₁ ).

Case 1) When δ _{1 is} greater than TH _p , or when δ ₁ belongs to the fixed time window adjustment set B, it is considered that the current power adjustment is only maintained within the effective time window. After the effective time window, the power adjustment fails and the transmission power needs to be adjusted back. (P ₁ +δ ₀ ), before the next power control information analysis is successful, the transmission power is equal to (P ₁ +δ ₀ ).

Case 2) When δ _{1 is} not greater than TH _p , or when δ ₁ belongs to the long-term effective adjustment set A, the current power adjustment is considered to be effective for a long time. Before the next power control information analysis is successful, the transmission power is equal to (P ₁ +δ ₀ + δ ₁ ) or (P ₁ +δ ₁ ).

When the terminal uses power control information, it needs to select different aging information (ie, adjust the effective time) based on different power adjustments. In this way, both the above cases 1) and 2) can use the TPC transmission mechanism, and the terminal does not need to perform additional Signaling detection. In case 1), at the end of the effective time window, the power adjustment is invalid. When there is no conflict between URLLC and eMBB, the interference caused by the power adjustment to the system can be avoided.

Through the above solution, when URLLC and eMBB resources conflict, the transmission power of URLLC is adjusted (increased), so that URLLC has sufficient SINR during decoding, thereby ensuring the reliability of URLLC transmission. Moreover, with the current power control information, no additional PDCCH transmission/detection requirements are added. One TPC signaling can realize the adjustment of the transmission power, and make the power adjustment invalid after the aging time expires, which can save signaling overhead.

Example two

(1) The terminal receives power control information, the power control information includes at least a power adjustment amount (increase or decrease), and the power control information is carried in the TPC dedicated DCI for transmission.

(2) The terminal performs corresponding operations based on the power control information. For example, the transmission power is adjusted according to the power control information, and the power adjustment is effective for a long time or for a fixed time window. If there are data transmission resources configured in advance, the service data is transmitted based on the power adjustment result.

For a specific example, the current terminal transmission power is (P ₁ +δ ₀ ), when the power adjustment amount δ ₁ indicated in the DCI, if the cumulative power adjustment mode is used, the transmission power needs to be adjusted to (P ₁ +δ ₀ +δ ₁ ). If the absolute value power adjustment mode is used, the transmission power needs to be adjusted to (P ₁ +δ ₁ ).

Case 1) When δ _{1 is} greater than TH _p , or when δ ₁ belongs to the fixed time window adjustment set B, it is considered that the current power adjustment is only maintained within the effective time window. After the effective time window, the power adjustment fails and the transmission power needs to be adjusted back. (P ₁ +δ ₀ ), before the next power control information analysis is successful, the transmission power is equal to (P ₁ +δ ₀ ). For CG-GRANT's URLLC data transmission, if it occurs within the valid time window, the power (P ₁ +δ ₀ +δ ₁ ) or (P ₁ +δ ₁ ) is used to send the data. If the data transmission occurs after the time window, power (P ₁ +δ ₀ ) is used to send the data.

Case 2) When δ _{1 is} not greater than TH _p , or when δ ₁ belongs to the long-term effective adjustment set A, the current power adjustment is considered to be effective for a long time. Before the next power control information analysis is successful, the transmission power is equal to (P ₁ + δ ₀ +δ ₁ ) or (P ₁ +δ ₁ ). For CG-GRANT's URLLC data transmission, power (P ₁ +δ ₀ +δ ₁ ) or (P ₁ +δ ₁ ) is used to send data.

It should be noted that the transmission power adjustment of the technical solution of the embodiment of the application is mainly for uplink data, and is not limited to this. The technical solution of the embodiment of the application can also be applied to the adjustment of the transmission power of other signals, such as uplink control. Channel, side line data.

It should be noted that the embodiment of the present application takes the transmission conflict of URLLC and eMBB as an example for description, and it is not limited to this. Other situations of service transmission conflicts of different levels may be applicable to the technical solutions of the embodiments of the present application.
