detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

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

1) Using the analog-digital hybrid beamforming architecture, the operation based on the beam (especially the analog beam) is a big difference from the low frequency, and it is also a feature that the protocol design focuses on. For this, beam management is designed in related technologies related processes;

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

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

However, the relevant process of beam management in the related art cannot well support the Mutli-TRP transmission mechanism, so that the Mutli-TRP transmission mechanism cannot reflect the feature of effectively resisting blockage, thereby reducing the robustness of the system.

The reason why the related process of beam management in the related art cannot well support the Mutli-TRP transmission mechanism will be analyzed in detail below.

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

For downlink, beam measurement and reporting can be performed based on synchronization signal/physical broadcast channel block (SSB) and/or channel state information reference signal (CSI-RS). Taking beam measurement and reporting using CSI-RS as an example, in the NR system, N (greater than or equal to 1) reporting configurations (Reporting Settings) (which can be called CSI reporting configurations (CSI -ReportConfig)), M (greater than or equal to 1) resource configuration (ResourceSettings) (can be called CSI resource configuration (CSI-ResourceConfig)), 1 or 2 trigger state lists (trigger states lists) (for dynamic Trigger multiple CSI resource sets (CSI Resource Sets) in the aperiodic CSI Resource Setting, including the aperiodic trigger state list (aperiodicTriggerStateList) and the semi-persistent physical uplink shared channel trigger state list (semiPersistentOnPUSCH-TriggerStateList)). Each CSI Reporting Setting can be configured as a periodic, semi-persistent or aperiodic reporting method. When the report quality (reportQuantity) in the radio resource control (RRC) signaling is configured as cri-RSRP (instructing the UE to report CSI-RS resource indication symbol (CRI) and L1-Reference Signal Received Power (RSRP)), that is, according to the non-zero power (NZP CSI-RS) to perform downlink beam measurement and L1-RSRP reporting, the network side will pass the channel used in RRC signaling The measured resources (resourcesForChannelMeasurement) associate a CSIResource Setting with each CSI Reporting Setting, and the time-domain behavior of the CSI Reporting Setting and the time-domain behavior of the CSI Resource Setting need to satisfy the relationship shown in Table 1.

Table 1

Wherein, each CSI Resource Setting may include S (greater than or equal to 1) CSI ResourceSets, and each CSI Resource Set may include several NZP CSI-RS Resources. For periodic or semi-persistent CSI Resource Setting, the constraint S=1. The network side can enable or disable group-based beam reporting (groupBasedBeamReporting) in RRC signaling. When groupBasedBeamReporting is configured as enabled, the UE reports 2 different CRIs each time. And the UE can receive data on the NZP CSI-RS resource 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 ReportingSetting for the UE and associate it with a periodic CSI Resource Setting. The CSI Resource Setting contains 1 CSI Resource Set, and the CSI Resource Set contains several NZP CSI-RS Resource. 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, because in actual applications, the base station sends data to the UE Generally, the beam corresponding to the CRI with the largest L1-RSRP is used, as shown in Figure 1; when groupBasedBeamReporting is configured as enabled, the UE reports 2 CRIs each time, which can be used for gNB Multi-panel transmission and the UE also has multiple panels 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 when actually sending data to the UE. The beam sent to the UE sends data, as shown in FIG. 2 .

Secondly, a detailed analysis is made on the reason why the related process of beam management in the related art 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 UE's Panel 1 and Panel 2, thereby reducing the occurrence of blockage The probability.

At present, the relevant process of beam management in related technologies cannot well support the operation in the above scenario. The problem is analyzed in detail as follows:

The first possible operation mode is: in the scenario shown in Figure 3, the network side configures two periodic CSI Reporting Settings for the UE, namely CSI Reporting Setting 1 and CSI Reporting Setting 2; and CSI Reporting Setting 1 is associated with A periodic CSI Resource Setting 1, which contains 1 CSI Resource Set 1, CSI Resource Set 1 contains 5 NZP CSI-RS Resources (NZP CSI-RSResource 1-1 to NZP CSI-RS Resource 1-5), respectively Corresponding to the five Tx beams (transmission beams) of TRP1, the network side configures groupBasedBeamReporting=disabled of CSI Reporting Setting 1 for UE, and nrofReportedRS=2; CSI Reporting Setting 2 is associated with a periodic CSI Resource Setting2, which contains 1 CSI Resource Set 2, CSI Resource Set 2 includes 5 NZP CSI-RS Resources (NZP CSI-RS Resource2-1 to NZP CSI-RS Resource 2-5), corresponding to the 5 Tx beams of TRP2, and the network side configures CSI Reporting for the UE The groupBasedBeamReporting of Setting 2 is disabled, and nrofReportedRS=2.

Then, for CSI Reporting Setting 1, assuming that after measurement, 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 UE will report CRI 1-1 (corresponding to NZP CSI-RS Resource 1-1) and CRI1-2 (corresponding to NZP CSI-RSResource 1-2); for CSI Reporting Setting 2, it is assumed that after measurement, the UE finds that panel 1 is used to receive NZP CSI-RS Resource 2-1 has better performance, using Panel2 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 -RSResource 2-2).

In this case, the problem is that when the network side performs Multi-TRP transmission according to the user's reported information, it first needs to determine which beam each TRP uses to transmit to the UE, and the beams used by different TRPs need UE 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 beam2-1 for Multi-TRP transmission, then both beams correspond to UE's Panel 1, but if UE uses Panel 1 to receive data, there is It may not be possible to receive the data of beam1-1 and beam2-1 at the same time, or there is a lot of interference between the data transmitted by TRP1 and TRP2.

The second possible operation mode 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 ResourceSetting, which contains 1 CSI Resource Set, CSI Resource Set contains 10 NZP CSI-RSResources (NZP CSI-RS Resource 1-1 to NZP CSI-RS Resource 1-5 and NZP CSI-RSResource 2-1 to NZP CSI-RS Resource 2-5), corresponding to TRP1 The 5 Tx beams of TRP2 and the 5 Tx beams of TRP2, the network side configures groupBasedBeamReporting of CSI Reporting Setting to enabled for UE.

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 NZPCSI-RS Resource 2-1, using Panel 2 to receive NZP CSI-RS Resource1-2 has the best performance, and NZPCSI-RS Resource 2-2 is next, 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, because according to the reported results of the UE, both CRI 1-1 and CRI 1-2 correspond to the TRP 1 beam, there is no TRP 2 beam, but the probability of TRP 1 being blocked is much greater than the probability of being blocked when using TRP 1 and TRP 2 for Multi-TRP transmission, that is, TRP 1 uses Beam1-1 and TRP2 uses Beam2-2 The Multi-TRP transmission system is more robust.

The third possible operation mode is: in the scenario shown in Figure 3, the network side configures two periodic CSI Reporting Settings for the UE, namely CSI Reporting Setting 1 and CSI Reporting Setting 2; and CSI Reporting Setting 1 is associated with A periodic CSI Resource Setting 1, which contains 1 CSI Resource Set 1, CSI Resource Set 1 contains 5 NZP CSI-RS Resources (NZP CSI-RSResource 1-1 to NZP CSI-RS Resource 1-5), respectively Corresponding to the 5 Tx beams of TRP1, the network side configures groupBasedBeamReporting of CSI Reporting Setting 1 to enabled for UE; CSI Reporting Setting 2 is associated with a periodic CSI Resource Setting 2, which contains 1 CSI Resource Set2, and CSI Resource Set 2 contains 5 The NZP CSI-RS Resource (NZP CSI-RS Resource 2-1 to NZPCSI-RS Resource 2-5) corresponds to the five Tx beams of TRP2 respectively, and the network side configures groupBasedBeamReporting of CSI ReportingSetting 2 for the UE as enabled.

Then, for CSI Reporting Setting 1, assuming that after measurement, 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 UE will report CRI 1-1 (corresponding to NZP CSI-RS Resource 1-1) and CRI1-2 (corresponding to NZP CSI-RSResource 1-2); for CSI Reporting Setting 2, UE has measured and found that panel 1 is used to receive NZPCSI-RS Resource 2- 1 performance is better, use 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 RSResource 2-2).

In this case, the problem is that when the network side performs Multi-TRP transmission according to the user's reported information, it first needs to determine which beam each TRP uses to transmit to the UE, and the beams used by different TRPs need UE It can be received at the same time. However, gNB cannot make such a judgment 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 reported result of the UE, The network side knows that the UE can receive Beam1-1 and Beam1-2 at the same time, and can also receive Beam2-1 and Beam2-2 at the same time, but the network side still does not know whether TRP 1 uses Beam1-1 and TRP 2 uses Beam2-1. Multi-TRP transmission, and it is not known whether TRP 1 uses Beam1-1 and TRP2 uses Beam2-2 to perform Multi-TRP transmission at the same time.

To sum up, the beam management process in the Rel 15 version protocol cannot well support high-frequency Multi-TRP data transmission, and cannot well enable its anti-high-frequency blockage characteristics, which will reduce the robustness of the system.

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

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

Step 401: For one channel state information reporting configuration (expressed as CSI ReportingSetting in English) configured by the terminal, associate Q1 channel state information resource configurations (expressed as CSIResource Setting in English) with the channel state information reporting 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 can also be performed based on SSB, and beam measurement and reporting can also be performed based on CSI-RS and SSB. Therefore, the expression form of channel state information can be CSI-RS can also be SSB, and can also be CSI-RS and SSB.

Based on this, the network device will configure the specific form of channel state information for the terminal. 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 a representation form of the channel state information.

In practical applications, in order to reduce signaling overhead, the existing configuration message can be used to configure the configuration information in step 401. Taking CSI-RS as an example, for example, the following information is added to the existing configuration message:

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

In actual application, the channel state information reporting configuration configured for the terminal may be configured in a periodic, semi-persistent or aperiodic reporting manner.

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

Wherein, Q2 is less than or equal to Q1.

Each set of beam information may include multiple (or 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 know the number of groups of beam information reported.

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 to say, 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 smaller 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 at the same time, so that the network device can know the information corresponding to each 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 identification of the channel state information resource configuration corresponding to each group of beam information reported by the terminal, such as index related information and the like.

In practical applications, when configuring the channel state information report configuration, you need to configure the group-based beam reporting parameter (groupBasedBeamReporting in English). The group-based beam reporting parameter can be configured as enabled or disabled. The network device may determine that the group-based beam reporting parameter is configured as enabled or disabled as required.

Wherein, when the group-based beam reporting parameter is configured as disabled, each group of beam information reported by the terminal is configured to include M first signal indicators and the L1-RSRP corresponding to each first signal indicator; this means that the The terminal can receive channel state information resources corresponding to X first signal indicators at the same time, and the X first signal indicators are respectively from different groups in the Q2 group of beam information.

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

Here, the value of M is the same as the number of CRIs (nrofReportedRS) reported by the terminal each time when the group-based beam reporting parameter (ie, groupBasedBeamReporting) is configured as disabled in the related art. Therefore, in the embodiment of the present invention, the M Defined as when 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 (panels) of the terminal antenna, and for example, it can be determined according to the number of beams that the terminal can receive simultaneously. The value of N may be 2 or the like.

In practical applications, beam measurement and reporting may 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 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 in the form of SSB, the first signal includes SSB; when the configured channel state information is in the form of 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 an SSB sequence number; when the first signal includes In case of CSI-RS and SSB, the first signal indicator includes CRI and SSB.

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

Step 501: receiving 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.
