Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a power control method, apparatus, device, and computer readable storage medium.

Background technique

In the existing spectrum sensing, the high and low priority judgment of the service is implemented by using a Reference Signal Receiving Power (RSRP) decision threshold. In this way, it is possible to consider the exclusion of longer distances for high-priority users, and the exclusion of relatively close distances for low-priority users, thereby indirectly reflecting the priority service high-priority services. However, from the final effect, the received signal strength indication (RSSI) exclusion and time-frequency resource spatial multiplexing and frequency division multiplexing itself do not reflect the difference between high and low priorities.

In addition, in the case of the same Modulation and Coding Scheme (MCS), the difference between the signal to interference plus noise ratio (SINR) of the service is different from the priority (PPPP) difference. It is also possible to consider whether the service is segmented, and for segmented services, it may be considered to increase its SINR requirement. The current sensing process only considers PPPP differences.

In the related art, the power control process of the Physical Sidelink Shared Channel (PSSCH) can be regarded as only related to the number of physical resource blocks (PRBs), but the transmission power is used as a transmission parameter, and there is no The specific process cannot reflect the difference in business of different priorities.

Detailed ways

Specific embodiments of the present disclosure will be further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the disclosure, but are not intended to limit the scope of the disclosure.

As shown in FIG. 1, the power control method of the embodiment of the present disclosure includes:

Step 101: Determine priority information of a current service to be transmitted.

The current to-be-transmitted service may refer to the service currently being processed. Different services can have different priority information, and the priority information of different services can be preset. For example, the voice call service can be set to have a higher priority, and the short message service has a lower priority.

Step 102: Determine, according to the priority information of the current to-be-transmitted service, the sending power of the current to-be-transmitted service.

In the embodiment of the present disclosure, the transmission power of the current to-be-transmitted service may be determined by combining different application scenarios and priority information of the current to-be-transmitted service.

Scene 1: Transmission mode 3 (Mode 3) in single-carrier scenario and transmission mode 4 (Mode 4) in coverage

(1) In this scenario, the current to-be-transmitted services of different priorities may have different transmit powers based on different expected receive powers of different priorities. When other network conditions are the same, the higher the priority, the higher the expected received power, and the higher the corresponding transmit power. The terminal side can be notified by means of parameter configuration, and a high expected power value is set for high priority, for example, a gain of 1 dB is added for high priority.

In a specific application, the expected received power corresponding to the current to-be-transmitted service may be set first, and then the transmit power of the current to-be-transmitted service is calculated by using the expected received power.

Specifically, the sending power of the current to-be-transmitted service is calculated by using the expected received power according to the following formula:

In the above formula, for mode3 or in-mode mode4 (regardless of whether Constant Bit Rate (CBR) control is enabled), the priority of different services can be reflected by the expected received power P _{O_PSSCH, 3} or P _{O_PSSCH, 4.} difference.

(2) In this scenario, the current to-be-transmitted services of different priorities may have different transmission powers based on different power spectral densities of different to-be-transmitted services. In the case where other network conditions are the same, the higher the priority, the larger the power spectral density, and the higher the corresponding transmission power.

In a specific application, the power spectral density corresponding to the current to-be-transmitted service may be set first, and then the power spectral density is used to calculate the transmit power of the current to-be-transmitted service.

Specifically, the sending power of the current to-be-transmitted service is calculated according to the following formula:

The P _PSSCH indicates the transmission power of the current to-be-transmitted service, the M _PSSCH indicates the transmission bandwidth of the PSSCH, the M _PSCCH indicates the transmission bandwidth of the PSCCH, the P _CMAX indicates the maximum transmission power allowed by the UE, and the P _{O_PSSCH, i} indicates the transmission mode 3 or the transmission mode.

Scenario 2: Transmission mode 3 (Mode 3) in the carrier aggregation scenario and transmission mode 4 (Mode 4) in the coverage.

In this scenario, it is assumed that the current to-be-transmitted service includes a first to-be-transmitted service and a second to-be-transmitted service, wherein the first to-be-transmitted service has a higher priority than the second to-be-transmitted service.

Then, in this step, the preset total transmit power may be obtained first, and then the transmit power of the first to-be-transmitted service is determined. And determining, in the remaining transmit power, whether the remaining transmit power meets a transmit requirement of the second to-be-transmitted service. And when the remaining transmit power meets the sending requirement of the second to-be-transmitted service, determining a transmit power for the second to-be-transmitted service; otherwise, the second to-be-transmitted service may not be transmitted. The remaining transmit power is equal to the total transmit power minus the transmit power of the first to-be-transmitted service.

In a specific application, under Carrier Aggregation (CA), when one subframe is transmitted, and the subframe needs to carry both high-priority services and low-priority services, the power distribution of each carrier is as follows:

Power resources are allocated preferentially for carriers carrying high priority services. The calculation method of the transmission power requirement covering the mode 4 and the mode 3 can be determined according to the calculation method in the prior art. Calculating the remaining power resources, allocating the remaining power resources to carriers carrying low priority services or determining whether the remaining power resources can meet the transmission requirements of carriers carrying low priority services. Sent if the demand is met, or not if the demand is not met.

In this scenario, the power requirements for the high- and low-priority services can be implemented according to the existing protocol, or can be implemented according to the calculation method of the scenario 1.

Specifically, in this scenario, if the expected received power of the first to-be-transmitted service is considered, the expected received power corresponding to the first to-be-transmitted service may be set, wherein the priority of the first to-be-transmitted service is increased. High, the value of the expected received power is increased, and the transmit power of the first to-be-transmitted service is calculated by using the expected received power. Specifically, the sending power of the first to-be-transmitted service is calculated according to the following formula:

Specifically, in this scenario, if the power spectral density of the first to-be-transmitted service is considered, the power spectral density corresponding to the first to-be-transmitted service may be set, where the priority of the first to-be-transmitted service is The value of the power spectral density increases, and the transmission power of the first to-be-transmitted service is calculated by using the power spectral density.

Specifically, the sending power of the first to-be-transmitted service is calculated according to the following formula:

The P _PSSCH represents the transmission power of the first to-be-transmitted service, the M _PSSCH represents the transmission bandwidth of the PSSCH, the M _PSCCH represents the transmission bandwidth of the PSCCH, the P _CMAX represents the maximum transmission power allowed by the UE, and the P _{O_PSSCH, i} represents the transmission mode 3 or the transmission. The expected received power in mode 4, α _{PSSCH, i} represents the higher layer parameter in transmission mode 3 or transmission mode 4, i=3 or 4; n represents the power spectral density of the PSCCH relative to the PSSCH carrying the first to-be-transmitted service Offset; PL represents the estimated link path loss.

Scene 3, Out of Transmission Mode 4 (Mode 4)

In this scenario, the power spectral density of the current to-be-transmitted service is determined according to the priority information of the current to-be-transmitted service, where the power spectral density increases as the priority of the current to-be-transmitted service increases. Increase. Then, according to the power spectral density, the transmission power of the current to-be-transmitted service is determined.

For example, suppose that full power transmission is considered in this scenario, and the current set scheduling allocation (SA) has a gain of 3 dB with respect to data (data). Therefore, in practical applications, it may be considered that services of different priorities are different from SA. Power Spectral Density (PSD), which in turn calculates the power distribution of SA and data when transmitting at full power.

For example, the settings in Table 1 below can be used:

Table 1

When the SA indicates a low priority service, the SA has a gain of 3 dB compared to data; when the SA indicates a high priority service, the SA has a gain of only 2 dB compared to data.

Scenario 4: Transmission mode 3 (Mode 3) in the carrier aggregation scenario and transmission mode 4 (Mode 4) outside the coverage.

In this scenario, it is assumed that the current to-be-transmitted service includes the first to-be-transmitted service and the second to-be-transmitted service, wherein the first to-be-transmitted service has a higher priority than the second to-be-transmitted service.

Specifically, determining, according to the priority of the first to-be-transmitted service and the priority of the second to-be-transmitted service, the first power spectral density of the first to-be-transmitted service and the second to-be-transmitted service a second power spectral density, wherein the first power spectral density is greater than the second power spectral density, and determining, according to the first power spectral density and the second power spectral density, respectively, the sending of the first to-be-transmitted service Power and transmission power of the second to-be-transmitted service.

Specifically, the calculation method of the transmission power of the first to-be-transmitted service is taken as an example, and can be calculated according to the following formula:

The P _{PSSCH, 1} indicates the transmission power of the first to-be-transmitted service, M _{PSSCH, 1} indicates the transmission bandwidth of the PSSCH carrying the first to-be-transmitted service, and M _{PSSCH, 2} indicates the transmission bandwidth of the _PSSCH carrying the second to-be-transmitted service. M _PSCCH indicates the transmission bandwidth of the PSCCH, P _CMAX indicates the maximum transmission power allowed by the UE, P _{O_PSSCH, i} indicates the expected reception power in the transmission mode 3 or the transmission mode 4, and α _{PSSCH, i} indicates the transmission mode 3 or the transmission mode 4 a high-level parameter, i=3 or 4; n1 represents a power spectral density offset of a PSSCH carrying the second to-be-transmitted service with respect to a PSSCH carrying the first to-be-transmitted service; n2 represents a PSCCH with respect to the bearer The power spectral density offset of the PSSCH of the traffic to be transmitted, and PL represents the estimated link path loss.

The calculation method of the transmission power of the second to-be-transmitted service is the same.

For a certain resource and bearer (determining the service with the determined priority on the resource), under Carrier Aggregation (CA), when transmitting once, the subframe needs to carry both high-priority services and low-priority carriers. For service, each carrier power allocation can be determined based on the power spectral density.

For example, the PSDs of different priority services may be determined according to the mapping relationship in Table 2 below, and the transmit power values on the respective SAs and resources carrying different data are determined.

Table 2

As can be seen from the above description, in the embodiment of the present disclosure, the transmission power of the current to-be-transmitted service can be determined according to the priority information of the current to-be-transmitted service, thereby ensuring the QoS of the high-priority service.

In practical applications, there may be other different application scenarios.

For example, when applied in a single carrier coverage scenario, when determining the transmission power, the high priority traffic has a higher transmission power, and the low priority traffic has a lower transmission power. For the specific implementation method, refer to the description of scenario one above.

For another example, when applied to a single carrier coverage scenario, when determining the transmission power, the high priority traffic has a higher transmission power, and the low priority traffic has a lower transmission power. For the specific implementation method, refer to the description of the above scenario 3.

For another example, under the CA, the services sent at one time (at the same time point) have both high priority and low priority (different service packets are multiplexed together to select one resource to be sent together), and power is preferentially allocated for high priority. For the specific implementation method, refer to the description of the foregoing scenario 2; when it is applied to the outside of the coverage, the specific implementation method may refer to the description of the foregoing scenario 3.

For another example, under the CA, the services sent at one time (at the same time point) have both high priority and low priority (the different time points of different service packets triggering the selection of resources, but only the same subframe is selected), and The high and low priority power values are different. For the specific implementation method, refer to the description of the foregoing scenario 2; when it is applied to the outside of the coverage, the specific implementation method may refer to the description of the foregoing scenario 3.

For another example, under the CA, different high and low priority services are sent at different times. For large-segment segmentation, where multiple carriers are occupied, the total power transmitted may be in the largest protocol regardless of the coverage or coverage. Each carrier divides the power in units of PRB, and considers the PSD between SA and data.

For another example, under CA, at different times, high and low priority services are sent. For a large packet segmentation, a scenario that occupies multiple carriers. Within the coverage, the total power can be calculated according to the above scenario 1, and then each carrier divides the power in units of PRB, while considering the PSD between SA and data.

In the embodiment of the present disclosure, if the priority of the service is not distinguished, the power spectrum offset (PSD offset) of the PSCCH with respect to the PSSCH is a fixed value of 3 dB. Assume that the priority of the service is differentiated, assuming that the PSD offset of the PSCCH is 3 dB with respect to the PSSCH carrying the high priority service, and the PSD offset of the PSSCH carrying the high priority service is 1 Db with respect to the PSSCH carrying the low priority service, then the single carrier In the scenario, if the high-priority service is sent, the power spectrum offset of the PSCCH relative to the PSSCH carrying the high-priority service is 3; if the low-priority service is sent, the PSCCH is relative to the PSSCH carrying the low-priority service. The power spectrum offset has a value of 4.

With the solution of the embodiments of the present disclosure, optimization of the existing sensing process can be achieved. The high-priority high-power spectral density and low-priority low-power spectral density have the following effects on the sensing process:

Resource exclusion: the same receiving RSRP, high priority is equivalent to considering the exclusion of longer distances; low priority equivalents exclude relatively low distances;

Resource selection: When RSSI is sorted, the difference between high and low priorities is also considered.

Time-frequency domain collision: From the perspective of SINR, it is assumed that all resources occupy the same size. If different powers are used, the power density spectrum is different. In this way, no matter whether "partial resource overlap collision/interference or collision/interference of all resources overlap occurs, for a user, collision/interference low priority user equivalent is less interference, high priority user pair The interference is larger. It is equivalent to the high-priority user, which has large receiving power, small interference, and large equivalent SINR; low-priority users have small receiving power, large interference, and the equivalent SINR is small;

The frequency domain near-far effect: equivalent to improving the power of high-priority services and improving the decoding rate of high-priority services.

As shown in FIG. 2, the power control apparatus of the embodiment of the present disclosure includes:
