In the embodiment of the present invention, the network device is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like.

As shown in fig. 1, an embodiment of the present invention provides a beam quality measurement method 100, which may be performed by a terminal device, in other words, may be performed by software or hardware installed in the terminal device, and includes the following steps:

s102: a plurality of RSs are received.

In this embodiment, the multiple RSs are transmitted by the network device through the target transmit beam, and the terminal device receives the multiple RSs with the target receive beam. Specifically, as shown in fig. 2, fig. 2 shows that the network device is a Transmission Receive Point (TRP) as an example.

The multiple RSs may be Reference signals used for beam quality measurement, and specifically, for example, the multiple RSs are all Channel State Information Reference signals (CSI-RSs); for another example, the RSs are all Synchronous Signal Blocks (SSBs); for another example, the RSs are a combination of one or more CSI-RSs and one or more SSBs.

Optionally, the multiple RSs satisfy a Quasi Co-Location (QCL) relationship, where the QCL relationship is used to indicate that the resources of the multiple RSs have one or more same or similar communication features, and the multiple RSs may adopt the same or similar communication configurations.

S104: a beam quality indicator for the target beam pair is determined based on the received plurality of RSs.

The target beam pair includes a transmission beam and a reception beam, as shown in fig. 2, the transmission beam being a transmission beam for the network device to transmit the RSs; the reception beam, i.e., the reception beam in which the terminal device receives the plurality of RSs.

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

In this embodiment, the terminal device may jointly calculate a beam quality indicator on Resource Elements (REs) of the plurality of RSs, where the beam quality indicator may include CSI parameters (parameters), calculated beam quality, or the like.

Optionally, the beam Quality indicator may include at least one of Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).

Optionally, the terminal device may calculate the beam quality indicators obtained by the multiple RSs respectively through at least one of the following algorithms to obtain the beam quality indicator of the target beam pair: linear averaging; geometric averaging; blending and averaging; square averaging; 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 example and its simple variation.

Specifically, for example, the number of the plurality of RSs is two, and the plurality of RSs are a first RS and a second RS, respectively, and the terminal device may perform linear average operation on the beam quality indicator (for example, RSRP) of the first RS and the beam quality indicator (the beam quality indicator of the first RS is the same type, for example, both RSRP) of the second RS, and use an obtained result as the beam quality indicator of the target beam pair.

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

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

P-2: the UE measures a plurality of transmission beams of the TRP and selects a transmission beam of the TRP. Typical scenario: achieving a more accurate transmit beam sweep over a small range than P-1 can be seen as a special case of P-1. 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 a receive beam of the UE. The UE does not report to the TRP.

Optionally, for the above processes P-1 and P-2, after determining the beam quality indicator of the target beam pair based on the multiple RSs in S104 of the above embodiment, the following steps may be further included: and sending a beam measurement report, wherein the beam measurement report comprises the beam quality index and the identification of the target RS.

The identifier of the target RS and the transmission beam transmitted by the network device to the multiple RSs have an association relationship, so that the network device can recognize the transmission beam transmitting the multiple RSs after receiving the identifier of the target RS, and can subsequently perform data or signal transmission between the terminal device and the transmission beam.

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

Specifically, 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 a CSI-RS, the identifier of the target RS is a CSI-RS index.

According to the beam quality measuring method provided by the embodiment of the invention, the terminal equipment receives the multiple RSs, and jointly determines the beam quality index of the target beam pair through the multiple RSs, so that compared with a scheme of determining the beam quality index of the target beam pair by adopting one RS in the related art, the beam quality measuring method can improve the beam quality measuring precision, reduce the time domain filtering time and achieve the purpose of faster and more accurate beam training.

The following explains in detail the implementation principle of the beam quality measurement method provided by the embodiment of the present invention:

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 may employ 8 receiving beams and the network device configures the terminal device with 16 RSs, the network may correspond to the terminal device with one beam every 2 RSs. However, the terminal device can only detect on its own RE, and in the beam report, the terminal device can only report the beam quality of each RS, which makes it impossible to utilize the resources to the maximum extent.

The embodiment of the present invention provides a beam quality index for jointly detecting a target beam pair by multiple RSs, which is also the above example, and a terminal device may measure the quality of the beam on REs of 2 RSs and perform linear averaging, so that the convergence rate of beam measurement is doubled. If one beam is detected using more RSs, 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, the number of terminal equipment and the service type of the terminal equipment in the system, and the system performance is improved.

For example, when the number of terminal devices is large, the RS for beam training of each terminal device is configured to be relatively few (may still be multiple), and the training speed is reduced to some extent; when the number of the terminal devices is small, the RS for the beam training of each terminal device can be configured more relatively, and the training is accelerated. For example, assuming that the number of terminal devices in the current cell is small, the network device may send a larger number of RSs, and the multiple RSs improve the accuracy of beam measurement. Assuming that the number of terminal devices in the current cell is large, the network device can transmit fewer RSs, thereby reducing occupied downlink resources and improving downlink system capacity.

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

For the above mentioned reduction of the temporal filtering time, the following will explain its principle in detail:

because the terminal device has an error in beam detection (or measurement), the beam itself may change over time, and the result of a single measurement is often inaccurate. Therefore, the result of the beam measurement needs to be subjected to layer 1 filtering in the time domain, and measurement accuracy is improved and the influence of time variation is reduced through multiple measurements in time. Even, layer 3 filtering is performed on the basis of the result of layer 1 filtering, so as to further improve the quality of beam measurement.

In the embodiment of the invention, the beam quality index of the target beam pair is determined by combining the multiple RSs by increasing the number of the RSs, so that the measurement precision of the beam quality can be improved. Meanwhile, the time domain resources of the multiple RSs can be relatively close to each other, and even the same time domain resources can be occupied (through frequency domain differentiation), so that the layer 1 filtering and the layer 3 filtering can be reduced or even omitted, and the time domain filtering time can be reduced.

Optionally, in the embodiment of the present invention, it may also be considered that a function of jointly detecting multiple RSs is implemented under the condition that the influence on the existing protocol is as small as possible, and in order to achieve the above effect, three different configuration methods, all of which are methods with a small change on the existing protocol, are considered in the embodiment of the present invention, and a specific configuration method for jointly detecting a single beam by multiple RSs is described in detail in the following three embodiments.

Example one

The RS (the RS received in S102 of the embodiment 100, and the following similar) is configured through higher layer signaling, and the higher layer signaling includes one of the following:

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

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

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).

Specifically, for example, the state of a certain higher layer signaling is configured to be "on" in the higher layer configuration signaling, and the terminal device may be instructed to receive the multiple RSs through the higher layer signaling.

In a first embodiment, when the terminal device sends a beam measurement report, the beam measurement report includes an identifier of a target RS, where the target RS may be in all RSs associated with the higher layer signaling:

the identification number is largest;

the identification number is the smallest;

a first configuration;

the last one is configured; or

Either one of them.

It can be understood that the identification number of the target RS is the largest among all RSs associated with the higher layer signaling; the identification number is the smallest; in these cases, the network device knows which specific target RS is reported by the terminal device subsequently when configuring the multiple RSs for the terminal device.

In this case, when configuring the plurality of RSs, the network device generally does not know which RS identifier the terminal device may subsequently report, and the network device knows only after receiving the identifier of the (target) RS included in the beam measurement report, and may subsequently use the (target) RS for beam correlation indication.

It should be noted that, the first/last configured RS mentioned in the embodiments of the present specification may specifically mean that the RS is in the first/last configuration order, for example, the network device configures multiple RSs simultaneously, then the RS in the first configuration is the first in the configuration order, and the RS in the last configuration is the last in the configuration order.

It should be further noted that, in the embodiments of the present specification, the RS of the higher layer signaling "association" is mentioned, where "association" may also be replaced by other similar technical terms, such as "indicate", "configure", and the like.

Specifically, for example, when the higher layer signaling is CSI measurement configuration signaling (CSI-MeasConfig), the higher layer signaling may be associated with CSI resource configuration signaling (CSI-resourceconconfig), and the CSI resource configuration signaling may be used to configure a resource set, where the multiple RSs are included in the resource set. Similarly, the CSI measurement configuration signaling may also directly configure an RS resource and/or an RS resource set, and the RS associated with the higher layer signaling — CSI measurement configuration signaling may be multiple RSs configured by the RS resource and/or multiple RSs included in the RS resource set.

For another example, when the higher layer signaling is CSI resource configuration signaling (CSI-ResourceConfig), the higher layer signaling may configure a resource set, and the multiple RSs are included in the resource set, in this case, the RS associated with the higher layer signaling-CSI resource configuration signaling may also be referred to as an RS configured by the higher layer signaling-CSI resource configuration signaling.

For another example, when the higher layer signaling is CSI report configuration signaling (CSI-report configuration), the higher layer signaling may be associated with CSI resource configuration signaling, and the CSI resource configuration signaling may be used to configure a resource set, where the multiple RSs are included in the resource set, in this case, the RS associated with the higher layer 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 indicated by the network device configuration, may be selected by the terminal device autonomously, or may be agreed by the protocol. Specifically, for example, the target RS included in the beam measurement report sent by the protocol-agreed terminal device is configured first in all RSs associated with the higher layer signaling.

Optionally, the repetition on configuration (repetition) of the higher layer signaling may be in an on state, so that the network device may repeatedly transmit the multiple RSs through the same transmission beam, which is convenient for the terminal device to scan multiple reception beams thereof to determine one or multiple reception beams with better beam quality.

Optionally, in the first embodiment, the RSs associated with the higher layer signaling all configure the same QCL information.

Optionally, in the first embodiment, QCL information of the RS associated with the higher layer signaling (except for the target RS, since the RS associated with the higher layer signaling may also include the target RS) follows QCL information of the (follow) target RS, which is an RS used for beam measurement report in the plurality of RSs. In this embodiment, if the QCL information is configured, the RS associated with the higher layer signaling (except for the target RS), regardless of whether the QCL information of the RS is the same as that of the target RS, may ignore the originally configured QCL information and follow the QCL information of the target RS; of course, if the RSs associated with the higher layer signaling (except the target RS) are not configured with QCL information, these RSs may directly follow the QCL information of the target RS.

Example two

The RSs are included in a RS list (list) configured by the network device, where the RS list includes identifiers of the RSs.

In this embodiment, the network device may configure one or more RS lists. In one example, the network device configures a plurality of RS lists, one RS list is associated with one transmission beam of the network device, and any two RS lists are associated with different transmission beams.

In the second embodiment, when the terminal device sends the beam measurement report, the beam measurement report includes an identifier of a target RS, and the target RS may be in an RS list:

the identification number is the largest;

the identification number is the smallest;

a first configuration;

the last configuration;

either one of them; or

Indicated by the network device (e.g., the network device is separately labeled in the RS list).

Optionally, the target RS included in the beam measurement report may be indicated by the network device configuration, may be selected by the terminal device autonomously, or may be agreed by the protocol. Specifically, for example, the target RS included in the beam measurement report sent by the protocol-agreed terminal device is configured first in the RS list.

Optionally, RSs in the RS list are contained in the same resource set (resource set). Of course, the RSs in the RS list may belong to different resource sets.

EXAMPLE III

The plurality of RSs are configured with the same QCL information, or one RS of the plurality of RSs is configured with QCL information of another one or more RSs.

Optionally, the multiple RSs configure the same QCL information, and when the terminal device transmits a beam measurement report, the beam measurement report includes an identifier of a target RS, where the target RS is:

the identification number is the largest;

the identification number is the smallest;

a first configuration;

the last one is configured; or

Either one of them.

Optionally, the target RS included in the beam measurement report may be indicated by the configuration of the network device, may be selected autonomously by the terminal device, or may be agreed by a protocol.

Optionally, the multiple RSs configure the same QCL information, and when the terminal device sends a beam measurement report, the beam measurement report includes an identifier of a target RS, where the target RS is an RS in CSI report configuration (CSI-report configuration) associated with the multiple RSs, and a report quantity (reportQuantity) is configured as one of the following RSs:

a channel state information reference signal Resource Indicator (CSI-RS Resource Indicator, CRI) -RSRP;

SSB-Index (Index) -RSRP;

CRI-SINR；

SSB-Index-SINR。

in this embodiment, if there are a plurality of RSs that satisfy the above requirement (i.e., RSs whose report amount is configured as one of the above), the target RS included in the beam measurement report may be any one of the RSs that satisfy the requirement, or the RS whose identification number is the largest; or the identification number is the smallest.

Optionally, the multiple RSs configure the same QCL information, and when the terminal device transmits a beam measurement report, the beam measurement report includes an identifier of a target RS, where the target RS:

preferably SSB;

preferably CSI-RS;

the priority is determined according to the priority selected by the terminal equipment, for example, the terminal equipment selects the target RS as SSB preferentially; or

Is determined according to the priority of the network device configuration, for example, the network device configuration indicates that the target RS is preferred to be the SSB.

Optionally, the target RS included in the beam measurement report may be indicated by the configuration of the network device, may be selected autonomously by the terminal device, or may be agreed by a protocol. Specifically, for example, the target RS included in the beam measurement report sent by the protocol-agreed terminal device is configured first in the RS list.

Optionally, in case that one RS of the plurality of RSs is configured as QCL information of the other one or more RSs, the "one RS" is the target RS, i.e., the target RS of the plurality of RSs is configured as QCL information of the other one or more RSs.

Optionally, in the high-level signaling to which at least one RS of the multiple RSs belongs, a certain high-level signaling is configured to be "on" to trigger the joint detection of the wave number quality index of the target beam pair by the multiple RSs in this embodiment.

Optionally, a certain higher layer signaling is configured to be "on" in the configuration information of at least one RS of the multiple RSs to trigger the joint detection of the wave number quality index of the target beam pair by the multiple RSs in this embodiment.

Optionally, the multiple RSs are included in the same resource set. Of course, the multiple RSs may belong to different resource sets.

In the foregoing embodiments, in the case that the terminal device transmits a beam measurement report, the beam measurement report includes an identifier of a target RS, and the target RS is associated by a higher layer signaling; or RS associated with higher layer signaling, preferably or necessarily target RS (i.e. RS carried in beam measurement report); wherein, the higher layer signaling mentioned in this embodiment includes one of the following:

failure detection resource signaling (failureDetectionResources);

beam failure detection resource list signaling (beamFailureDetectionResourceList);

radio link monitoring configuration signaling (radio link monitoring config);

the radio link listens for reference signal signaling (radiolinkmentiringrs).

In this embodiment, the terminal device may select one RS from the multiple RSs associated with the higher layer signaling as a target RS; or, the RS associated with the higher layer signaling needs to be or preferentially the RS carried in the beam measurement report.

In the embodiment, different purposes of the RS are considered, and for RS types with high requirements on timeliness, for example, the RS used for Beam Failure Detection (BFD) or the RS used for Radio Link Monitoring (Radio Link Monitoring), the wavenumber quality index of a target Beam pair can be jointly detected by multiple RSs according to protocol requirements or preferentially.

In this embodiment, optionally, the high-layer signaling includes a radio link monitoring rs signaling, and a destination signaling in the radio link monitoring rs signaling is configured as one of the following:

beam failure (beamFailure);

a radio link failure (rlf);

both of which comprise (booth).

Specifically, for example, the signaling purpos in the radiolinkmultioringrs is configured as "beamFailure"/"rlf"/"both".

In the foregoing embodiments, in a case that a terminal device sends a beam measurement report, the beam measurement report includes an identifier of a target RS, where the target RS is associated by a higher layer signaling; or RS associated with higher layer signaling, preferably or necessarily target RS (i.e. RS carried in beam measurement report); wherein, the higher layer signaling mentioned in this embodiment includes one of the following:

candidate beam reference signal list signaling (candidate beamersist);

candidate beam resource list signaling (candidabeamresourcelist), candidabeamrslist, includes a reference signal list (CSI-RS and/or SSB) indicating the recovered candidate beams and associated random access parameters.

In this embodiment, the terminal device may select one RS from the multiple RSs associated with the higher layer signaling as a target RS; or, the RS associated with the higher layer signaling may be an RS carried in the beam measurement report.

The embodiment considers different purposes of the RS, and for RS types with high timeliness requirements, for example, RS for a New candidate beam (New candidate beam) in Beam Failure Recovery (BFR), the wave number quality index of a plurality of RS joint detection target beam pairs can be required or prioritized by a protocol.

In the foregoing embodiments, in a case where a terminal device sends a beam measurement report, the beam measurement report includes an identifier of a target RS, and in a CSI report configuration (CSI-report configuration) associated with the target RS, a report quantity (reportQuantity) is configured as one of the following; or in the CSI reporting configuration associated with the multiple RSs, the RS associated when the reporting quantity is configured as one of the following RS, must or preferentially be the target RS (i.e. the RS carried in the beam measurement report):
