Description

Beam determination method, device, communication equipment and storage medium Technical field

The present disclosure relates to but is not limited to the field of communication technology, and in particular, to a beam determination method, device, communication equipment and storage medium.

Background technique

In related technologies, the uplink beam selection of user equipment (User Equipment, UE) is selected based on the reference signal receiving power (RSRP) of the beam. At the same time, the uplink co-frequency and homogeneity principle of Time Division Duplexing (TDD) UE can be used to select the uplink beam in the same direction as the downlink beam direction to achieve better coverage.

When considering the UE uplink beam, the impact of the UE's Special Absorb Rate (SRA) needs to be additionally considered. Since SAR considers the UE's requirements for human body radiation, there are specific power limit requirements for the UE's uplink transmit power. The UE's power reduction is mainly reported to the UE through the Maximum allowed UE output power reduction (P-MPR). UE. Currently, since there is only one fixed P-MPR for each UE in the calculation of UE uplink power, the configuration or scheduling of uplink beams is inaccurate.

In order to facilitate understanding by those skilled in the art, the embodiments of the present disclosure enumerate multiple implementations to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided in the embodiments of the present disclosure can be executed alone or in combination with the methods of other embodiments in the embodiments of the present disclosure. They can also be executed alone or in combination. It is then executed together with some methods in other related technologies; the embodiments of the present disclosure do not limit this.

In order to better understand the technical solution described in any embodiment of the present disclosure, first, a partial description of the related technology is provided:

In some application scenarios, in UE uplink power calculation, P-MPR has only one fixed value for each UE. In this way, the UE does not need to additionally consider the impact of P-MPR power backoff when selecting uplink beams.

In the new NR technology, beam-level P-MPR reporting is introduced, that is, each beam has its own unique P-MPR value. When performing P-MPR reporting, due to the limit of the UE's reporting capability, the UE needs to report at least one beam according to its own capabilities for reference by the base station for subsequent configuration.

As shown in Figure 2, a schematic diagram of the UE's uplink beam and downlink beam selection is provided. For example, the selected uplink beams are r1, r2, r3 and r4; the selected downlink beams are t1, t2, t5 and t6.

In other application scenarios, considering the UE's uplink performance is not only the UE's uplink power (such as RSRP), but also the duration of the uplink transmission (such as the maximum uplink transmission time). In some specific application scenarios, the priority may be higher than the UE's uplink power (such as RSRP). More power. Regarding the SAR requirements of the UE, one is the power and the other is the uplink transmission time; therefore, in the scheduling of the UE by the network equipment, the maximum uplink duty cycle (maxuplink duty cycle) is also a factor that affects the SAR and uplink performance. In the embodiment of the present disclosure, the maximum uplink duty cycle is positively correlated with the maximum uplink transmission time.

Based on the RSRP and maximum uplink transmission time, the UE needs to formulate a strategy to provide the base station with enough information to make beam selection and uplink scheduling decisions; otherwise, it will cause the loss of uplink coverage, or the uplink transmission rate will slow down, or uplink coverage will need to be long-term. The business cannot be scheduled for a long enough time, resulting in performance degradation.

As shown in Figure 3, an embodiment of the present disclosure provides a beam determination method, which is executed by a UE, including:

Step S31: Send at least one capability information of at least one beam of the UE, where the capability information is used to determine the beam used by the UE for transmission;

Among them, the capability information includes at least one of the following:

RSRP and P-MPR;

Maximum upstream transmission time;

RSRP and maximum uplink transmission time;

RSRP, P-MPR and maximum uplink transmission time.

Here, the UE may be various mobile terminals or fixed terminals. For example, the UE may be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU, Road Side Unit), a game control platform or a multimedia device, etc.

Sending at least one capability information of at least one beam of the UE in step S31 may be: sending at least one capability information of at least one beam to the network device.

Here, the network equipment may be network elements or functions of various core networks or access networks. For example, the network device may be a logical node that can be flexibly deployed in the communication network, and the network device is not limited here.

In some embodiments, the network device may be a base station; the base station may be various types of base stations, for example, it may be a 2G base station, a 3G base station, a 4G base station, a 5G base station or an evolved base station.

In one embodiment, the capability information may also include: the maximum uplink duty cycle. Here, the maximum uplink duty cycle is positively correlated with the maximum uplink transmission time.

In one embodiment, the at least one beam of the UE includes at least one uplink beam of the UE. Here, the beam used by the UE for transmission is determined, that is, the uplink beam used by the UE for uplink transmission is determined.

At least one beam in step S31 refers to at least one beam reported. For example, the UE supports M beams, and the UE can select at least one capability of N beams from the M beams to report; the N beams are at least one beam in step S31.

Exemplarily, the UE sends two pieces of capability information of at least one beam to the network device; where the capability information includes: RSRP and P-MPR. In this way, after receiving the capability information of the at least one beam, the network device may determine one or more beams for scheduling the UE based on the RSRP and P-MPR included in the capability information of the at least one beam. In the embodiment of the present disclosure, the plurality is two or more.

Exemplarily, the UE sends a piece of capability information of at least one beam to the network device, where the capability information includes: maximum uplink transmission time. In this way, after receiving the capability information of the at least one beam, the network device may determine to schedule one or more beams of the UE based on the maximum uplink transmission time included in the capability information of the at least one beam.

In this embodiment of the present disclosure, at least one capability information of at least one beam can be reported by the UE, where the capability information is used to determine the beam used by the UE for transmission; this allows the UE to report beam-level capability information, such as the RSRP and P of the beam. -MPR, or the maximum uplink transmission time of the beam, or the RSRP and maximum uplink transmission time of the beam, or the RSRP, P-MPR and maximum uplink transmission time of the beam, so that the network device receives the beam level capability information of the UE , the beam of the UE that needs to be scheduled can be accurately determined according to the actual situation.

For example, the power backoff (P-MPR) of the power of different beams (RSRP) of the UE can be taken into account, so that the beam for scheduling the UE determined by the network device can meet the requirements of the SAR and provide uplink coverage. For another example, the maximum uplink transmission time of different beams of the UE can be taken into consideration, and different maximum uplink transmission times can be determined for different services, thereby improving the uplink transmission rate and taking into account the uplink coverage.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: determining the P-MPR of at least one beam based on SAR safety information.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: determining the maximum uplink transmission time of at least one beam based on SAR safety information.

For SAR security information, the maximum uplink transmission times of different beams of the determined UE are the same or different.

In this embodiment of the present disclosure, the UE can determine the P-MPR and/or the maximum uplink transmission time of at least one beam based on the SAR security information; in this way, the P-MPR and/or the maximum uplink transmission time of at least one beam that needs to be reported can be accurately determined. Transmission time so that the network equipment can determine the appropriate scheduled beam for each UE.

In this way, in the embodiments of the present disclosure, the beam-level capability information of the UE can be accurately determined.

It should be noted that those skilled in the art can understand that the methods provided by the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

As shown in Figure 4, an embodiment of the present disclosure provides a beam determination method, which is executed by a UE, including:

Step S41: Based on the reporting capability information of the UE, determine at least one beam that needs to be reported.

In some embodiments of the present disclosure, at least one beam in step S41 may be at least one beam in step S31. In step S41, at least one beam that needs to be reported is determined, that is, at least one capability information of at least one beam that the UE needs to send is determined.

Here, the reporting capability information is used to indicate the UE's reporting beam capability.

In one embodiment, the reporting capability information is used to indicate the ability to report the number of beams. For example, the UE supports the second number of beams, and the reporting capability of the UE is the ability to report the first number of beams.

In some embodiments, the number of beams reported by the UE is: the number of beams reported by the UE reporting capability information.

In some embodiments, step S41 includes: selecting the first number of beams as at least one beam from the second number of beams based on the reporting capability information of the UE indicating that the first number of beams is reported and the UE supports the second number of beams. Report; the first quantity is less than or equal to the second quantity.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: reporting a first number of beams based on the reporting capability information indication of the UE and the UE supporting a second number of beams, and selecting the first number from the second number of beams. beams are reported as at least one beam; the first number is less than or equal to the second number.

Here, the second number of beams are beams supported by the UE; the first number of beams are beams that the UE needs to report.

Here, the first number of beams may be randomly selected from the second number of beams.

For example, the reporting capability of the UE is the ability to report N beams; the UE supports M beams, so the UE can select N beams from the M beams for reporting; here, M and N are both integers greater than 0, and M is greater than or equal to N. Here, M may be the second quantity, and N may be the first quantity.

In this way, in this embodiment of the present disclosure, the UE may select the first number of beams indicated by the UE reporting capability information from the second number of beams supported by the UE as at least one beam for reporting. In this way, the UE can be made to report at least one capability information of at least one beam if it meets the reporting capability.

In another embodiment, reporting capability information is also used to indicate the ability to report the capability information. For example, the UE may determine at least one beam that needs to be reported based on at least one capability of the beams supported by the UE.

In some embodiments, selecting the first number of beams from the second number of beams as at least one beam for reporting includes:

Based on the difference between the RSRP and the P-MPR of at least one beam in the second number of beams, determine the first number of beams whose difference satisfies the first predetermined range for reporting; or,

Based on the difference between the RSRP and the P-MPR of each beam in the second number of beams, a first number of beams whose differences satisfy the first predetermined range are determined and reported.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: determining at least one beam that needs to be reported based on the P-MPR of the second number of beams supported by the UE.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: based on a difference between RSRP and P-MPR of at least one beam in a second number of beams, determining a first number of beams whose difference satisfies a first predetermined range. Beam is reported.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: based on the difference between RSRP and P-MPR of each beam in the second number of beams, determining a first number of beams whose differences satisfy a first predetermined range Make a report.

Here, the first number of beams whose differences satisfy the first predetermined range are determined to be reported, including but not limited to one of the following:

Determine the first number of beams with the smallest difference to report;

The first number of beams with the largest difference is determined and reported.

In one embodiment, the RSRP may be L1-RSRP.

In one embodiment, the difference between RSRP and P-MPR is P=(L1-RSRP)-(P-MPR).

For example, the UE supports M beams, and the UE's reporting capability is to report N beams. The UE determines the difference between the RSRP and P-MPR of the M beams; then the UE determines that the N beams with the smallest difference between the RSRP and the P-MPR are at least one beam that needs to be reported, and sends the RSRP and P-MPR of the N beams. -MPR. Here, M is the second quantity and N is the first quantity.

In this way, in the embodiment of the present disclosure, if the difference between the RSRP and the P-MPR of the beam is a relatively small value, the RSRP can be relatively large and the P-MPR can be relatively large; in this way, the impact of the beam on human body radiation can be considered Small simultaneous uplink coverage is relatively strong.

For example, the UE supports M beams, and the UE's reporting capability is to report N beams. The UE determines the difference between RSRP and P-MPR of M beams; then the UE determines that the N beams with the largest difference between RSRP and P-MPR are at least one beam that needs to be reported, and sends the RSRP and P-MPR of the N beams. -MPR. Here, M is the second quantity and N is the first quantity.

In this way, in the embodiment of the present disclosure, if the difference between the RSRP and the P-MPR of the beam is a relatively large value, the P-MPR can be relatively small when the RSRP is the same; in this way, the P-MPR can be relatively small when the path loss is the same. The performance of the beam is relatively good, that is, the uplink coverage is relatively strong.

Of course, in other embodiments, the difference satisfying the first predetermined range is not limited to: the first number of values with the smallest difference or the first number of values with the largest difference; the difference can also satisfy the first predetermined range. Yes: the difference is less than or equal to the first value and greater than or equal to the second value, where the first value is greater than the second value.

In some embodiments, selecting the first number of beams from the second number of beams as at least one beam for reporting includes:

Based on the maximum uplink transmission time of at least one beam in the second number of beams, determine the first number of beams whose maximum uplink transmission time satisfies the second predetermined range for reporting; or,

Based on the maximum uplink transmission time of each beam in the second number of beams, a first number of beams whose maximum uplink transmission time satisfies the second predetermined range are determined and reported.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: based on the maximum uplink transmission time of at least one beam among the second number of beams, determining a first number of beams whose maximum uplink transmission time satisfies a second predetermined range. Report.

Embodiments of the present disclosure provide a beam determination method, executed by a UE, including: based on the maximum uplink transmission time of each beam in the second number of beams, determining a first number of beams whose maximum uplink transmission time satisfies a second predetermined range for reporting. .

Here, the first number of beams whose maximum uplink transmission time satisfies the second predetermined range are determined to be reported, including but not limited to one of the following:

Determine the first number of beams with the largest maximum uplink transmission time and report them;

Determine the first number of beams with the smallest maximum uplink transmission time and report them.

For example, the UE supports M beams, and the UE's reporting capability is to report N beams. When the UE determines the maximum uplink transmission time of M beams, the UE determines that the N beams with the largest maximum uplink transmission time are at least one beam that needs to be reported, and sends the maximum uplink transmission time of the N beams. Here, M is the second quantity and N is the first quantity.

In this way, in the embodiment of the present disclosure, if the determined maximum uplink transmission time of the reporting beam is relatively large, services requiring relatively long uplink transmission time and/or low reliability requirements may be applied.

For example, the UE supports M beams, and the UE's reporting capability is to report N beams. When the UE determines the maximum uplink transmission time of the M beams, the UE determines that the N beams with the smallest maximum uplink transmission time are at least one beam that needs to be reported, and sends the maximum uplink transmission time of the N beams. Here, M is the second quantity and N is the first quantity.

In this way, in the embodiment of the present disclosure, if the determined maximum uplink transmission time of the reporting beam is relatively small, services requiring a relatively short uplink transmission time and/or a relatively high reliability requirement may be applied.

Of course, in other embodiments, the maximum uplink transmission time satisfying the second predetermined range is not limited to: the first number of values with the smallest maximum uplink transmission time or the first number of values with the largest maximum uplink transmission time; the maximum uplink transmission time The time satisfying the second predetermined range may also be: the maximum uplink transmission time is less than or equal to the third value and greater than or equal to the fourth value, where the third value is greater than the fourth value.

In some embodiments, selecting a first number of beams from the second number of beams as at least one beam for reporting includes one of the following:

Based on the difference between the RSRP of at least one beam in the second number of beams and the maximum uplink transmission time, determine the first number of beams with the smallest difference for reporting;

Based on the difference between the RSRP of at least one beam in the second number of beams and the maximum uplink transmission time, determine the first number of beams with the largest difference for reporting;

Based on the difference between the RSRP of each beam in the second number of beams and the maximum uplink transmission time, determine the first number of beams with the smallest difference for reporting;

Based on the difference between each RSRP in the second number of beams and the maximum uplink transmission time, the first number of beams with the largest difference is determined and reported.

In this way, in the embodiment of the present disclosure, it may also be determined that the first number of beams need to be reported based on the difference between the RSRP of at least one beam in the second number of beams and the maximum uplink transmission time.

In some embodiments, the number of beams reported by the UE is less than or equal to the number of reported beams indicated by the UE's reporting capability information.

In some embodiments, step S41 includes:

Based on the reporting capability information of the UE and the service information of the UE, at least one beam that needs to be reported is determined.

Embodiments of the present disclosure provide a beam determination method, which is executed by a UE, including: determining at least one beam that needs to be reported based on the reporting capability information of the UE and the service information of the UE.

Here, the at least one beam that needs to be reported may be: at least one beam among the first number of beams. For example, if the reporting capability information of the UE indicates reporting a first number of beams, then at least one beam that needs to be reported is less than or equal to the first number of beams.

Here, the service information at least includes the transmission time of the service.

For example, the UE supports M beams, and the UE's reporting capability is to report N beams. The UE determines the maximum uplink transmission time of the M beams and determines that the transmission time of the service is the first duration; then the UE determines that the N beams with the maximum uplink transmission time greater than the first duration are at least one beam that needs to be reported, and sends the N The maximum uplink transmission time of the beam.
