Detailed ways

The application will be further described in detail below with reference to the drawings and embodiments.

As mentioned earlier, high-frequency communication has the following characteristics:

1) Adopting the analog-digital hybrid beamforming architecture, the operation based on the beam (especially the analog beam) is very different from the low frequency, and it is also a feature of the protocol design. For this, the beam management is designed in the related technology Related processes;

2) High frequencies are easily affected by occlusion, which can easily cause beam switching or even communication interruption. In view of this, in the R15 version, the multi-panel counter-blockage is also properly considered in the beam management.

Currently, the Mutli-TRP transmission mechanism is being discussed. For high frequencies, Mutli-TRP is also an effective means to counter blockage. Therefore, it is necessary to further appropriately enhance beam management to improve the robustness of high-frequency communications.

However, the related process of beam management in the related technology does not support the Mutli-TRP transmission mechanism well, so that it cannot reflect the characteristics of the Mutli-TRP transmission mechanism to effectively counter blockage, thereby reducing the robustness of the system.

The following is a detailed analysis of the reason why the related procedures of beam management in related technologies cannot support the Mutli-TRP transmission mechanism well.

First, the downlink beam management process in related technologies is described.

For the downlink, beam measurement and reporting can be performed based on SSB and/or CSI-RS. Taking the use of CSI-RS for beam measurement and reporting as an example, in the NR system, N (greater than or equal to 1) reporting settings can be configured for the user terminal (UE) (which can be referred to as CSI reporting configuration (CSI) -ReportConfig)), M (greater than or equal to 1) resource settings (Resource Settings) (can be called CSI resource configuration (CSI-ResourceConfig)), 1 or 2 trigger states lists (used for dynamic Multiple CSI resource sets (CSI Resource Sets) in aperiodic CSI Resource Setting, including aperiodic trigger state list (aperiodicTriggerStateList) and semi-persistent physical uplink shared channel trigger state list (semiPersistentOnPUSCH-TriggerStateList)). Each CSI Reporting Setting can be configured to be a periodic, semi-continuous or aperiodic reporting method. When the report quantity (reportQuantity) in the radio resource control (RRC) signaling is configured as cri-RSRP (instructs the UE to report the CSI-RS resource indicator) CSI-RS (NZP CSI-RS) for downlink beam measurement and L1-RSRP reporting, the network side will use the resources for channel measurement in RRC signaling (resourcesForChannelMeasurement) Associate a CSI Resource Setting for each CSI Reporting Setting. The time domain behavior of CSI Reporting Setting and the time domain behavior of CSI Resource Setting need to satisfy the relationship shown in Table 1.

Table 1

Among them, each CSI Resource Setting may include S (greater than or equal to 1) CSI Resource Sets, and each CSI Resource Set may include several NZP CSI-RS Resources. For periodic or semi-continuous CSI Resource Setting, the restriction is S=1. The network side can configure the group-based beam reporting (groupBasedBeamReporting) in RRC signaling to be enabled or disabled. When groupBasedBeamReporting is configured to be enabled, the UE reports two different CRIs each time. And the UE can receive data on the NZP CSI-RS resources corresponding to these two CRIs at the same time; when groupBasedBeamReporting is configured as disabled, the UE reports nrofReportedRS CRIs each time.

For example, the next-generation base station (gNB) can configure a periodic CSI Reporting Setting for the UE and associate it with a periodic CSI Resource Setting. The CSI Resource Setting includes 1 CSI Resource Set, and the CSI Resource Set includes Several NZP CSI-RS Resources. When groupBasedBeamReporting is configured as disabled, the UE reports nrofReportedRS CRIs each time, but the UE may not be able to receive data on the NZP CSI-RS resource (beam) corresponding to these CRIs at the same time. This is because: in actual application, the base station sends to the UE For data, the beam corresponding to the CRI with the largest L1-RSRP is generally used, as shown in Figure 1. When groupBasedBeamReporting is configured as enabled, the UE reports 2 CRIs at a time. This can be used for gNB Multi-panel transmission and there are multiple UEs. In the panel scenario, for example, the UE can use two panels to receive the data transmitted by the NZP CSI-RS resource corresponding to the two CRIs at the same time, so that the gNB can use different panels to use the two CRIs respectively when actually sending data to the UE. The corresponding beam sends data to the UE, as shown in Figure 2.

Secondly, analyze in detail the reason why the related procedures of beam management in related technologies cannot well support the Mutli-TRP transmission mechanism.

The Multi-TRP transmission mechanism is another effective means to combat blockage. As shown in Figure 3, a typical scenario is that TRP1 and TRP2 use different beams to transmit data with the UE’s Panel 1 and Panel 2 to reduce the occurrence of blockage. The probability.

At present, the related processes of beam management in related technologies cannot well support such operations in the above scenarios. In other words, in the presence of Multi-TRP, if the related processes of beam management in related technologies are directly used, there will be some The specific analysis is as follows:

The first possible operation method is: in the scenario shown in Figure 3, the network side configures two periodic CSI Reporting Setting for the UE, namely CSI Reporting Setting 1 and CSI Reporting Setting 2; and CSI Reporting Setting 1 is associated A periodic CSI Resource Setting 1, which contains 1 CSI Resource Set 1, and CSI Resource Set 1 contains 5 NZP CSI-RS Resources (NZP CSI-RS Resource 1-1 to NZP CSI-RS Resource 1-5), Corresponding to the 5 Tx beams (transmit beams) of TRP1, the network side configures the groupBasedBeamReporting=disabled of CSI Reporting Setting 1 for the UE, and nrofReportedRS=2; CSI Reporting Setting 2 is associated with a periodic CSI Resource Setting 2, which includes 1 CSI Resource Set 2, CSI Resource Set 2 contains 5 NZP CSI-RS Resources (NZP CSI-RS Resource 2-1 to NZP CSI-RS Resource 2-5), corresponding to the 5 Tx beams of TRP2, and the network side gives the UE Configure groupBasedBeamReporting of CSI Reporting Setting 2 as disabled, and nrofReportedRS=2.

Then, for CSI Reporting Setting 1, suppose that after measurement, the UE finds that using panel 1 to receive NZP CSI-RS Resource 1-1 has better performance, and using Panel 2 to receive NZP CSI-RS Resource 1-2 has better performance, so the UE will report CRI 1-1 (corresponding to NZP CSI-RS Resource 1-1) and CRI 1-2 (corresponding to NZP CSI-RS Resource 1-2); for CSI Reporting Setting 2, it is assumed that after measurement, the UE finds that the panel 1 is used to receive NZP CSI -RS Resource 2-1 performance is better, using Panel 2 to receive NZP CSI-RS Resource 2-2 performance is better, so UE will report CRI 2-1 (corresponding to NZP CSI-RS Resource 2-1) and CRI 2-2 (Corresponding to NZP CSI-RS Resource 2-2).

In this case, the problem is that when the network side performs Multi-TRP transmission according to the information reported by the user, it first needs to determine which beam each TRP uses to transmit to the UE, and the beams used by different TRPs require the UE. It can be received at the same time. However, the gNB cannot make such a judgment only based on the CRI 1-1 and CRI 1-2, CRI 2-1 and CRI 2-2 reported by the UE. So it may appear: if TRP 1 uses beam 1-1 and TRP 2 uses beam 2-1 for Multi-TRP transmission, then these two beams correspond to the UE's Panel 1, but if the UE uses Panel 1 to receive data, It is possible that the data of beam 1-1 and beam 2-1 cannot be received at the same time, or there is great interference between the data transmitted by TRP1 and TRP2.

The second possible operation method is: in the scenario shown in Figure 3, the network side configures a periodic CSI Reporting Setting for the UE; the CSI Reporting Setting is associated with a periodic CSI Resource Setting, which contains 1 CSI Resource Set , CSI Resource Set contains 10 NZP CSI-RS Resources (NZP CSI-RS Resource 1-1 to NZP CSI-RS Resource 1-5 and NZP CSI-RS Resource 2-1 to NZP CSI-RS Resource 2-5), Corresponding to the 5 Tx beams of TRP1 and the 5 Tx beams of TRP2 respectively, the network side configures the groupBasedBeamReporting of the CSI Reporting Setting for the UE as enabled.

Assuming that after measurement, the UE finds that using panel 1 to receive NZP CSI-RS Resource 1-1 has the best performance, followed by NZP CSI-RS Resource 2-1, using Panel 2 to receive NZP CSI-RS Resource1-2 has the best performance, and NZP CSI -RS Resource 2-2 second, so UE will report CRI 1-1 and CRI 1-2. In this case, the problem is that the network side cannot determine which beam each TRP uses to transmit to the UE. This is because according to the report result of the UE, CRI 1-1 and CRI 1-2 both correspond to TRP. The beam of 1 does not have the beam of TRP 2, but the probability of TRP 1 being blocked is much greater than the probability of being blocked when TRP 1 and TRP 2 are used for Multi-TRP transmission, that is, TRP 1 uses Beam 1-1 and TRP 2 uses Beam 2 -2 The Multi-TRP transmission system is more robust.

The third possible operation method is: in the scenario shown in Figure 3, the network side configures two periodic CSI Reporting Setting for the UE, namely CSI Reporting Setting 1 and CSI Reporting Setting 2; and CSI Reporting Setting 1 is associated A periodic CSI Resource Setting 1, which contains 1 CSI Resource Set 1, and CSI Resource Set 1 contains 5 NZP CSI-RS Resources (NZP CSI-RS Resource 1-1 to NZP CSI-RS Resource 1-5), Corresponding to the 5 Tx beams of TRP1, the network side configures the groupBasedBeamReporting of CSI Reporting Setting 1 as enabled for the UE; CSI Reporting Setting 2 is associated with a periodic CSI Resource Setting 2, which includes 1 CSI Resource Set 2, CSI Resource Set 2 Contains 5 NZP CSI-RS Resources (NZP CSI-RS Resource 2-1 to NZP CSI-RS Resource 2-5), corresponding to the 5 Tx beams of TRP2, and the network side configures the UE with CSI Reporting Setting 2’s groupBasedBeamReporting as enabled .

Then, for CSI Reporting Setting 1, suppose that after measurement, the UE finds that using panel 1 to receive NZP CSI-RS Resource 1-1 has better performance, and using Panel 2 to receive NZP CSI-RS Resource 1-2 has better performance, so the UE will report CRI 1-1 (corresponding to NZP CSI-RS Resource 1-1) and CRI 1-2 (corresponding to NZP CSI-RS Resource 1-2); for CSI Reporting Setting 2, the UE measured and found that panel 1 was used to receive NZP CSI- RS Resource 2-1 has better performance, using Panel 2 to receive NZP CSI-RS Resource 2-2 has better performance, so UE will report CRI 2-1 (corresponding to NZP CSI-RS Resource 2-1) and CRI 2-2 ( Corresponding to NZP CSI-RS Resource 2-2).

In this case, the problem is that when the network side performs Multi-TRP transmission according to the information reported by the user, it first needs to determine which beam each TRP uses to transmit to the UE, and the beams used by different TRPs require the UE. It can be received at the same time. However, gNB cannot make such a judgment only based on the CRI 1-1 and CRI 1-2, CRI 2-1 and CRI 2-2 reported by the UE. Specifically, according to the report result of the UE, The network side knows that the UE can receive Beam 1-1 and Beam 1-2 at the same time, and it can also receive Beam 2-1 and Beam 2-2 at the same time, but the network side still does not know TRP 1 uses Beam 1-1 and TRP 2 uses Beam 2 -1 Is it possible to perform Multi-TRP transmission at the same time? I don’t know whether TRP 1 uses Beam 1-1 and TRP2 uses Beam 2-2 whether it can perform Multi-TRP transmission at the same time.

In summary, the beam management process in the Rel 15 protocol cannot well support high-frequency Multi-TRP data transmission, and cannot well enable its features against high-frequency blockage, which will reduce the robustness of the system.

Based on this, in various embodiments of the present application, one channel state information report configuration configured by the network side for the terminal is associated with Q1>1 channel state information resource configuration for channel measurement (English expression as Channel Measurement), so that The terminal reports the Q2 group beam information, so that the network side can determine the beam used by each TRP according to the Q2 group beam information.

The embodiment of the application provides a data transmission method, which is applied to a network device (a base station (such as gNB in a fifth-generation mobile communication technology (5G) system, etc.), etc.), as shown in FIG. 4, the method includes:

Step 401: For one channel state information report configuration configured by the terminal (expressed as CSI Reporting Setting in English), configure Q1 channel state information resource configurations (expressed as CSI Resource Setting in English) for the channel state information report configuration;

Wherein, when configuring the channel state information report configuration, the configuration report quality parameter (reportQuantity in English) is CRI-RSRP; Q1 is an integer greater than 1.

In practical applications, beam measurement and reporting can be performed based on CSI-RS, beam measurement and reporting based on SSB, or beam measurement and reporting based on CSI-RS and SSB. Therefore, the form of channel state information can be CSI-RS can also be SSB, CSI-RS and SSB.

Based on this, the network device will configure the terminal with a specific form of channel state information. When performing beam measurement and reporting based on CSI-RS, configure it as CSI-RS; when performing beam measurement and reporting based on SSB, configure It is SSB; when performing beam measurement and reporting based on CSI-RS and SSB, it is configured as CSI-RS and SSB.

Here, in actual application, when configuring the channel state information report configuration, the network device may configure the expression form of the channel state information.

In actual applications, in order to reduce signaling overhead, the configuration information in step 401 can be configured using existing configuration messages. Taking CSI-RS as an example, for example, the following information is added to the existing configuration messages:

In practical applications, more than or equal to one channel state information report configuration can be configured for the terminal, and for each channel state information report configuration, more than one channel state information resource configuration is associated with the corresponding channel state information report configuration.

In practical applications, the channel state information report configuration configured for the terminal can be configured in a periodic, semi-continuous or aperiodic reporting manner.

Step 402: Receive the Q2 group beam information reported by the terminal based on the configuration information.

Among them, Q2 is less than or equal to Q1.

Each group of beam information can include multiple (or can be understood as several) first signal indicators and corresponding L1-RSRPs.

In practical applications, when Q2 is smaller than Q1, the network device needs to further configure the value of Q2 so that the terminal can learn the number of groups of reported beam information.

Based on this, in an embodiment, when configuring the channel state information report configuration, the method may further include:

Configure the value of Q2.

That is, the value of Q2 is indicated in the channel state information report configuration.

Here, in actual application, the network device may determine the value of Q2 as required.

Correspondingly, when Q2 is less than Q1, when the terminal reports the Q2 group of beam information, it can also report the identifier of the channel state information resource configuration corresponding to each group of beam information, so that the network device can know the corresponding group of beam information Channel state information resource configuration.

Based on this, in an embodiment, when receiving the Q2 group beam information reported by the terminal based on the configuration information, the method may further include:

Receive the identifier of the channel state information resource configuration corresponding to each group of beam information reported by the terminal, such as index related information.

In actual application, when configuring the channel state information report configuration, it is necessary to configure the group-based beam reporting parameters (in English expressed as groupBasedBeamReporting). The group-based beam reporting parameters can be configured as enabled or disabled. The network device may determine that the group-based beam report parameter is configured as enabled or disabled according to needs.

Wherein, when the configuration group-based beam report parameter is disabled, each group of beam information reported by the terminal is configured to include M first signal indicators and L1-RSRP corresponding to each first signal indicator; The terminal can simultaneously receive the channel state information resources corresponding to the X first signal indicators, and the X first signal indicators are from different groups in the Q2 group beam information.

When the group-based beam report parameter is configured as enabled, each group of beam information reported by the terminal includes N first signal indicators and L1-RSRP corresponding to each first signal indicator; the terminal can simultaneously receive N first signal indicators The channel state information resource corresponding to a signal indicator, or the channel state information resource corresponding to different groups of combined beam information in the Q2 group of beam information can be simultaneously received.

Here, the value of M is the same as the number of CRI reports (nrofReportedRS) that the terminal reports each time when the group-based beam reporting parameter (ie groupBasedBeamReporting) in the related technology is configured as disabled. Therefore, in this embodiment of the application, the M Defined as nrofReportedRS.

The value of N can be determined according to needs. For example, the value of N can be determined according to the number of panels of the terminal's antenna, and for example, it can be determined according to the number of beams that the terminal can receive at the same time. The value of N can be 2, etc.

In practical applications, beam measurement and reporting can be performed based on CSI-RS and/or SSB.

Based on this, in an embodiment, the first signal includes CSI-RS and/or SSB.

Wherein, the first signal is determined according to the expression form of the channel state information configured by the network device; specifically, when the expression form of the configured channel state information is CSI-RS, the first signal includes CSI-RS ; When the configured channel state information is expressed as SSB, the first signal includes SSB; when the configured channel state information is expressed in CSI-RS and SSB, the first signal includes CSI-RS and SSB .

When the first signal includes CSI-RS, the first signal indicator includes CRI; when the first signal includes SSB, the first signal indicator includes the SSB sequence number; when the first signal includes In the case of CSI-RS and SSB, the first signal indicator includes CRI and SSB sequence number.

Correspondingly, an embodiment of the present application provides a data transmission method applied to a terminal. As shown in FIG. 5, the method includes:

Step 501: Receive configuration information;

Here, the configuration information includes a channel state information report configuration, and Q1 channel state information resource configurations associated with the channel state information report configuration; Q1 is an integer greater than 1.

More specifically, the configuration information may include more than or equal to one channel state information report configuration, and more than one channel state information resource configuration associated with each channel state information report configuration.

Step 502: When the report quality parameter in the channel state information report configuration is CRI-RSRP, report the Q2 group beam information to the network side based on the configuration information.
