The network device may be a base station, and the base station may include various forms of macro base stations, micro base stations, relay stations, and access points. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in an LTE network, it is called an evolved NodeB (evolved NodeB, eNB, or eNodeB), and in a third generation (3rd Generation, 3G) network, it is called a Node B (Node B), or a subsequent evolutionary communication system. Network equipment, etc. However, the wording does not constitute a restriction.

As shown in FIG. 1, the present invention provides an embodiment of a beam quality measurement method 100. The method can be executed by a terminal device. In other words, the method can be executed by software or hardware installed on the terminal device. The method includes the following steps:

S102: Receive multiple RSs.

In this embodiment, the multiple RSs are sent by the network device through the target transmission beam, and the terminal device uses the target reception beam to receive the multiple RSs. The details are shown in Fig. 2, where Fig. 2 shows that the network device is a Transmission Receive Point (TRP) as an example.

The foregoing multiple RSs may be reference signals used for beam quality measurement. Specifically, for example, the foregoing multiple RSs are all channel state information reference signals (CSI-RS); for another example, the foregoing multiple RSs are all channel state information reference signals (CSI-RS). Synchronization signal block (Synchronization Signal and PBCH block, SSB for short); for another example, the multiple RSs are a combination of one or more CSI-RSs and one or more SSBs.

Optionally, the multiple RSs mentioned above satisfy the Quasi Co-Location (QCL) relationship, and the QCL relationship is used to indicate that the resources of the multiple RSs have one or more identical or similar communication characteristics. Each RS can adopt the same or similar communication configuration.

S104: Determine the beam quality index of the target beam pair based on the received multiple RSs.

The target beam pair includes a transmitting beam and a receiving beam. As shown in FIG. 2, the transmitting beam is the transmitting beam of the network device transmitting the above-mentioned multiple RSs; the receiving beam is the receiving beam of the terminal device receiving the multiple RSs.

Optionally, in this step, the terminal device may determine the beam quality index of the target beam pair based on the received multiple RSs and all the antenna ports corresponding to the multiple RSs.

In this embodiment, the terminal device may jointly calculate the beam quality index on the resource elements (Resource Elements, RE) of the multiple RSs. The beam quality index may include CSI parameters or calculated beam quality.

Optionally, the beam quality indicators may include reference signal received power (RSRP), reference signal receiving quality (RSRQ), and signal to interference plus noise ratio (SINR). ) At least one of.

Optionally, the terminal device may calculate the beam quality indicators respectively obtained by multiple RSs through at least one of the following algorithms to obtain the beam quality indicators of the target beam pair: linear average; geometric average; harmonic average; square average; weighted average ; The minimum value is maximized; the maximum value is minimized. Of course, the algorithm in the embodiment of the present invention is not limited to the above examples and simple changes thereof.

Specifically, for example, there are two multiple RSs, namely the first RS and the second RS. The terminal device can compare the beam quality index of the first RS (for example, RSRP) and the beam quality index of the second RS (and the beam quality index of the first RS). The types of beam quality indicators are the same, for example, all of them are RSRP) to perform a linear average operation, and the obtained result is used as the beam quality indicator of the target beam pair.

The beam quality measurement method provided by the embodiment of the present invention can be divided into the following three processes:

P-1: The UE measures the multiple transmit beams of the TRP and the receive beam of the UE, and selects the transmit beam of the TRP and the receive beam of the UE. Typical scenario: TRP scans multiple transmit beams, and UE scans multiple receive beams. The UE reports the selected at least one TRP transmission beam to the TRP.

P-2: The UE measures multiple transmit beams of the TRP and selects the transmit beam of the TRP. Typical scenario: Compared with P-1, it can be regarded as a special case of P-1 to achieve a small range and more accurate transmission beam scanning. The UE reports the selected at least one TRP transmission beam to the TRP.

P-3: The UE measures multiple receive beams of the UE on the same transmit beam of the TRP, and selects the receive beam of the UE. The UE does not report to the TRP.

Optionally, for the foregoing processes P-1 and P-2, after S104 of the foregoing embodiment determines the beam quality index of the target beam pair based on multiple RSs, the following step may be further included: sending a beam measurement report, the beam measurement report Including the above-mentioned beam quality index and the identification of the target RS.

There is an association relationship between the identification of the target RS and the transmission beams of the multiple RSs sent by the network device. In this way, after the network device receives the identification of the target RS, it can identify the transmission beams that send the multiple RSs. Data or signal can be transmitted between the transmitting beam and the terminal device.

The identifier of the target RS is information that can distinguish the target RS from other RSs. For example, the sequence used by the target RS may be used as the signal identifier, or the cyclic shift of the sequence generating the target RS may be used as the signal identifier, or The number of the target RS is the signal identifier.

For example, if the target RS is SSB, the identifier of the target RS is SSB index; for another example, if the target RS is CSI-RS, the identifier of the target RS is CSI-RS index.

In the beam quality measurement method provided by the embodiment of the present invention, a terminal device receives multiple RSs and jointly determines the beam quality index of the target beam pair through the multiple RSs. Compared with the related art, using one RS to determine the beam quality index of the target beam pair In terms of the solution, the measurement accuracy of the beam quality can be improved, the time-domain filtering time can be reduced, and the purpose of faster and more accurate beam training can be achieved.

The implementation principle of the beam quality measurement method provided by the embodiment of the present invention will be explained in detail below:

In the related art, one RS corresponds to one beam, and the network device cannot achieve the effect of improving the speed and accuracy of beam training by increasing the RS. For example, assuming that the terminal device can use 8 receiving beams, and the network device configures the terminal device with 16 RSs, then the network can correspond to one beam of the terminal device for every 2 RSs. However, the terminal device can only perform detection on each RS's own RE, and in the beam report, the terminal device can only report each RS's own beam quality, so that resources cannot be utilized to the maximum.

The embodiment of the present invention proposes multiple RSs to jointly detect the beam quality index of the target beam pair. The same is the above example. The terminal device can measure the quality of the beam on the REs of the 2 RSs and linearly average the beam quality, so that the beam measurement is converged. The speed has doubled. If a beam uses more RSs to detect, the convergence speed of the beam measurement can be improved even more.

Moreover, the network equipment can flexibly configure beam training according to the number of RS resources in the system, the number of terminal equipment, and the type of terminal equipment service to improve system performance.

For example, when the number of terminal devices is relatively large, the RS for beam training of each terminal device is relatively less configured (still can be more than one), and the training speed is reduced; when the number of terminal devices is relatively small, the RS for beam training of each terminal device is relatively small. You can configure more to speed up training. For example, assuming that the number of terminal devices in the current cell is small, network devices can send more RSs, and multiple RSs improve the accuracy of beam measurement. Assuming that the number of terminal devices in the current cell is large, the network devices can send fewer RSs, reducing the occupied downlink resources, and increasing the downlink system capacity.

For important services with high channel quality requirements, more RSs can be configured to make beam training more accurate; for services with general channel quality requirements, the beam training requirements can be reduced.

For the aforementioned reduction of time-domain filtering time, the principle will be explained in detail as follows:

Since the terminal equipment has errors in beam detection (or measurement), the beam itself will also change over time, and the result of a single measurement is often inaccurate. Therefore, the results of the beam measurement need to be filtered in the time domain, and multiple time measurements are used to improve the measurement accuracy and reduce the influence of time variation. Furthermore, it is necessary to perform layer 3 filtering on the basis of the result of layer 1 filtering to further improve the quality of beam measurement.

In the embodiment of the present invention, by increasing the number of RSs and jointly determining the beam quality index of the target beam pair through multiple RSs, the measurement accuracy of the beam quality can be improved. At the same time, the time domain resources of these multiple RSs can be relatively close, and can even occupy the same time domain resources (differentiated by frequency domain), which can reduce or even omit the above-mentioned layer 1 filtering and layer 3 filtering, thus reducing the time domain filtering time.

Optionally, the embodiment of the present invention may also consider implementing the function of multiple RS joint detection under the condition that the impact on the existing protocol is as small as possible. In order to achieve the above effect, the embodiment of the present invention considers three different configuration methods. , Are all methods with minor changes to the existing protocol. The following three embodiments will be divided into three embodiments to introduce in detail the specific configuration method for multiple RSs to jointly detect a single beam.

Example one

The foregoing multiple RSs (the multiple RSs received in S102 of the embodiment 100, the subsequent similarities) are configured through high-level signaling, and the high-level signaling includes one of the following:

1) CSI measurement configuration signaling (CSI-MeasConfig);

2) CSI report configuration signaling (CSI-ReportConfig);

3) CSI resource configuration signaling (CSI-ResourceConfig);

4) Non-zero power CSI-RS resource set signaling (NZP-CSI-RS-ResourceSet); or

5) CSI-SSB resource set signaling (CSI-SSB-ResourceSet).

For example, in the high-level configuration signaling, the state of a certain high-level signaling is configured to be "on", and the high-level signaling can instruct the terminal device to receive the multiple RSs.

In the first embodiment, when the terminal device sends the beam measurement report, the beam measurement report includes the identification of the target RS, and the target RS may be among all RSs associated with the above-mentioned high-level signaling:

The largest identification number;

The smallest identification number;

The first configuration;

The last configured; or

Any one.

It can be understood that in the cases where the target RS has the largest identification number, the smallest identification number, the first configuration, or the last configuration among all RSs associated with the above-mentioned high-level signaling, the network device is configuring the terminal device In the above multiple RSs, it is already known which target RS is subsequently reported by the terminal device.

In the case that the target RS is any one of all RSs associated with the above-mentioned high-level signaling, when the network equipment configures the above-mentioned multiple RSs, it usually does not know which RS identification may be reported by the terminal equipment subsequently, and the network equipment Only after receiving the identifier of the (target) RS included in the beam measurement report, the (target) RS can be used for beam-related instructions subsequently.

It should be noted that, the first/last configured RS mentioned in the various embodiments of this specification can specifically refer to the order of RS in the configuration as the first/last. For example, the network device is configured at the same time If there are multiple RSs, the first configured RS is the first in the configuration sequence, and the last configured RS is the last in the configuration sequence.

It should also be noted that, in the high-level signaling "associated" RS mentioned in the various embodiments of this specification, the "associated" can also be replaced by other similar technical terms, for example, "indication", "configuration" Wait.

Specifically, for example, when the high-level signaling is CSI measurement configuration signaling (CSI-MeasConfig), the high-level signaling can be associated with CSI resource configuration signaling (CSI-ResourceConfig), and CSI resource configuration signaling can be used to configure resource sets The above-mentioned multiple RSs are included in the resource set. In this case, the RS associated with the high-level signaling—CSI measurement configuration signaling may be multiple RSs included in the resource set configured by the CSI resource configuration signaling. Similarly, CSI measurement configuration signaling can also directly configure RS resources and/or RS resource sets. The high-level signaling—RS associated with CSI measurement configuration signaling may be multiple RSs configured and/or multiple RS resource sets. RS.

For another example, when the high-level signaling is CSI resource configuration signaling (CSI-ResourceConfig), the high-level signaling can configure a resource set, and the above-mentioned multiple RSs are included in the resource set. In this case, the high-level signaling— The RS associated with CSI resource configuration signaling can also be referred to as high-level signaling—RS configured by CSI resource configuration signaling.

For another example, when the high-level signaling is CSI report configuration signaling (CSI-ReportConfig), the high-level signaling can be associated with the CSI resource configuration signaling, and the CSI resource configuration signaling can be used to configure a resource set. It is included in the resource set. In this case, the RS associated with the high-level signaling—CSI report configuration signaling may be multiple RSs included in the resource set configured by the CSI resource configuration signaling.

Optionally, the target RS included in the beam measurement report may be instructed by the configuration of the network device, may also be independently selected by the terminal device, or may be agreed upon by a protocol. For example, the protocol stipulates that the target RS included in the beam measurement report sent by the terminal device is the first configured among all RSs associated with high-level signaling.

Optionally, the repetition configuration (repetition) of the above-mentioned high-level signaling may be in the on state, so that the network device can repeatedly send the above-mentioned multiple RSs through the same transmitting beam, so that the terminal device can scan its multiple receiving beams to determine the beam One or more receive beams with better quality.

Optionally, the RSs associated with the above-mentioned high-level signaling in the first embodiment are all configured with the same QCL information.

Optionally, the QCL information of the RS associated with the above-mentioned high-level signaling (except the target RS, because the RS associated with the above-mentioned high-level signaling may also include the target RS) in the first embodiment follows the QCL information of the target RS. RS is the RS used for beam measurement report among the above multiple RSs. In this embodiment, if the RS (except the target RS) associated with high-level signaling is configured with QCL information, no matter whether the QCL information of these RSs is the same as the QCL information of the target RS, these RSs can ignore the originally configured QCL information, and Follow the QCL information of the target RS; of course, if the RS (except the target RS) associated with the high-level signaling is not configured with QCL information, these RSs can directly follow the QCL information of the target RS.

The largest identification number;

The smallest identification number;

The first configuration;

The last configured;

Any one; or

Indicated by the network device (for example, the network device is separately marked in the RS list).

Optionally, the target RS included in the beam measurement report may be instructed by the configuration of the network device, may also be independently selected by the terminal device, or may be agreed upon by a protocol. For example, the protocol stipulates that the target RS included in the beam measurement report sent by the terminal device is the first configured in the RS list.

Optionally, the RSs in the RS list are included in the same resource set. Of course, the RSs in the RS list can also belong to different resource sets.
