The following first introduces the contents related to the scheme provided in the embodiments of the present application.

As shown in fig. 1, it shows a process based on aperiodic measurement reporting in the prior art, which mainly includes the following steps:

step 11: the base station selects a beam according to the measurement information reported by the terminal and carries out beam indication/updating (through MAC-CE or DCI 1);

step 12: the terminal performs HARQ/ACK feedback on the beam indication;

step 13: the new beam takes effect;

step 14: the base station sends DCI2, the terminal is triggered to carry out beam measurement on the appointed CSI-RS resource and report the measurement result on the indicated PUSCH resource;

step 15: and the terminal performs receiving measurement on the CSI-RS resource indicated by the base station in the step 14 by using the receiving beam of the beam indicated by the base station in the step 11 according to the indication of the base station, and reports a measurement result on the corresponding PUSCH resource according to the indication in the DCI 2.

Based on the above, embodiments of the present application provide a beam indicating method, a terminal, and a base station, so as to solve the problem in the prior art that a time delay of a beam measurement reporting process of aperiodic measurement is large when a beam is updated.

As shown in fig. 2, a beam indication method provided in an embodiment of the present application is applied to a terminal, and includes:

step S101, receiving a target beam for receiving indicated by a base station through a first bit of a first signaling, and beam measurement indication information of the target beam indicated by a second bit of the first signaling; or receiving beam measurement indication information of a target beam indicated by a second signaling by a base station when the target beam indicated by the base station through the first signaling is used for receiving is received;

in this step, specifically, the first signaling is a DCI signaling or a MAC-CE; the second signaling is DCI signaling; and the beam measurement indication information is used for triggering the terminal to carry out beam measurement and report on the target beam.

For example, the base station issues DCI1 for beam indication, where the DCI1 includes a Transmission Configuration Indicator (TCI state) state 1; the DCI1 includes a first bit indication in a first signaling for TCI state1, and the QCL type D RS included in the TCI state1 is a Synchronization Signal Block (SSB) 1 to indicate the terminal to receive/transmit a subsequent downlink/uplink Signal with a beam for receiving the SSB 1. Meanwhile, the base station indicates the terminal to perform subsequent aperiodic measurement reporting through a second bit (for example, 1 bit) in the DCI 1.

For example, the base station issues a beam indication DCI1, and simultaneously issues an independent uplink DCI2 to transmit beam measurement indication information, where the beam measurement indication information is used for the terminal to trigger beam measurement and reporting on a target beam.

Step S201, after the target wave beam is measured according to the wave beam measurement indication information, the measurement result information is reported.

In this step, when receiving the target beam indicated by the base station for reception to the terminal, the terminal triggers beam measurement on the target beam according to the received beam measurement indication information, where a reference signal resource used for beam measurement may be determined according to a predefined manner and according to a beam indication, or may be obtained through high-level configuration. The resources used for reporting the beam measurement result can be determined in a predefined manner.

In this embodiment, as a manner, a base station indicates, to a terminal, a target beam for reception through a first bit of a first signaling, and indicates, to the terminal, beam measurement indication information of the target beam through a second bit of the first signaling; or as another mode, when the base station indicates the target beam for receiving to the terminal through the first signaling, the base station indicates the beam measurement indication information of the target beam to the terminal through the second signaling; further, the terminal reports the measurement result information after measuring the target beam according to the beam measurement indication information. In this embodiment, since the signaling for triggering the beam measurement is not sent to the terminal after the new beam is generated, the processing time for beam measurement and reporting can be shortened, and the time delay in the beam measurement reporting process can be reduced.

Specifically, the second bit is one or more bits in the first signaling.

For example, one or more bits in the first signaling may be carried through an existing indication field. For example, "0001" indicates that the terminal performs beam measurement on TCI state 0. "0000" indicates that the terminal does not perform beam measurement for TCI state 0. Or, one or more bits in the first signaling may also be carried by an independently defined indication field. For example, a bit "0" indicates that beam measurement is performed on the indicated TCI state, and a bit "1" indicates that beam measurement is not performed on the indicated TCI state.

In an embodiment, the first signaling is associated with the second signaling.

In this embodiment, the terminal may quickly decode the second signaling through the first signaling and the association relationship between the first signaling and the second signaling, thereby reducing the processing delay.

Specifically, the first signaling is associated with the second signaling and is one of the following:

the 1 st: the first signaling comprises an indication domain used for triggering beam measurement, and the first signaling is associated with the second signaling through the indication domain;

for example, when the first signaling and the second signaling are DCI signaling, the associating the first signaling with the second signaling may include: the DCI signaling (first signaling) for the beam indication includes a DCI field for triggering beam measurement signaling (second signaling).

The 2 nd: the first signaling is associated with the second signaling on a time resource.

For example, the DCI signaling (second signaling) for triggering beam measurement is DCI for triggering first Channel State Information (CSI) reporting by the DCI signaling (first signaling) for triggering beam indication in the same time window (several slots).

Further, in an embodiment, the first signaling further includes a third bit, where the third bit is used as indication information indicating whether beam directions of associated reference signals are the same.

In this embodiment, the associated reference signals are the first reference signal and the CSI-RS, the first reference signal and the CSI-RS are associated through a quasi-co-located QCL, and the same beam direction of the associated reference signal indicated in the first signaling may be used to optimize the receiving beam; when the beam directions indicating the associated reference signals are not the same, it can be used to optimize the transmit beams.

In an embodiment, the method further includes: the terminal determines the resource for reporting the beam measurement result through at least one of the following modes:

mode A1: determining a Physical Uplink Shared Channel (PUSCH) which is latest scheduled after a time slot of a Physical Downlink Control Channel (PDCCH) carrying the first signaling as a resource for reporting a beam measurement result of the terminal; mode A2: determining a latest available PUSCH as a resource for reporting a beam measurement result by the terminal;

mode C: and determining the configured PUSCH based on the granted grant (granted) as a resource for reporting the beam measurement result of the terminal.

In an embodiment, after the step S101, the method further includes: the terminal determines a target reference signal resource used for beam measurement of a target beam by at least one of the following methods:

the first method is as follows:

in this method, a fixed set of CSI-RS resources dedicated to beam measurement is configured by RRC as a target reference signal resource for beam measurement.

Illustratively, the target reference signal Resource is a fixed non-zero power channel state information reference signal Resource set (NZP CSI-RS Resource set) configured by Radio Resource Control (RRC): { CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4}, as a set of CSI-RS resources dedicated for beam measurement.

The second method comprises the following steps:

Specifically, the second mode includes one of the following:

the first method comprises the following steps:

For example, a first non-zero power channel state information reference signal Resource Set (NZP-CSI-RS-Resource Set) M time slots after a time slot in which a PDCCH for carrying DCI1 (first signaling) is located is used as a reference signal Resource for beam measurement. The terminal receives and measures a reference signal for beam measurement with a reception beam of QCL type-D source RS contained in the TCI state.

And the second method comprises the following steps:

determining a set of channel state information reference signal (CSI-RS) resources associated with a first reference signal through a quasi co-located QCL as the target reference signal resource; wherein the first reference signal is a quasi co-located QCL type D source reference signal (QCL type D source RS) in a TCI state of a transmission control indication used for the first signaling;

for example, the associated CSI-RS resource set is configured within the QCL type-D source RS in the beam indication signaling (first signaling) by means of higher layer signaling configuration. For example, the target reference signal resource may be a resource in a CSI-RS resource set 1 associated with SSB1 configured by the base station through RRC before the base station transmits the first signaling, where SSB1 is a target beam indicated in the first signaling.

The beam indication and beam measurement reporting process of the present application is described in the following three specific embodiments.

Example 1: the determination mode of the target reference signal resource is as follows: a first mode (a fixed channel state information reference signal (CSI-RS) resource set which is configured by a higher layer and is specially used for beam measurement is determined as the target reference signal resource); and the case where the base station simultaneously transmits the beam measurement indication information through the same signaling indicating the beam is exemplified. The method can specifically comprise the following steps:

step one, a base station issues DCI1 for beam indication, a first bit in the DCI1 includes a Transmission Configuration Indicator (TCI) state1, and a QCL type D RS included in the TCI state1 is SSB1, which indicates a terminal to receive/transmit a subsequent downlink/uplink signal with a beam receiving the SSB 1. Meanwhile, the base station indicates the terminal to perform subsequent aperiodic measurement reporting through a second bit (for example, 1 bit) in the DCI 1.

The aperiodic measurement resource is a fixed NZP CSI-RS resource set configured by RRC: { CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4}.

Specifically, the configuration fields are as follows:

step two, the terminal receives the indication of the base station and determines that the non-periodic measurement report exists subsequently;

step three, the terminal determines that the measurement resources of the aperiodic CSI-RS are as follows: { CSI-RS1, CSI-RS2, CSI-RS3, and CSI-RS4};

and step four, the terminal receives the { CSI-RS1, CSI-RS2, CSI-RS3 and CSI-RS4} by using the wave beam for receiving the SSB1, and measures the received wave beam to obtain L1-RSRP1, L1-RSRP2, L1-RSRP3 and L1-RSRP4.

And step five, the terminal reports the beam CRI3+ L1-RSRP3 on the latest scheduled PUSCH after the time slot of the PDCCH carrying the DCI1 indicated by the beam according to the predefined resource indication.

And step six, the base station receives the report of the terminal, and transmits the PDCCH/PDSCH by using the wave beam for transmitting the CSI-RS3 in the subsequent downlink transmission.

Example 2:

as shown in fig. 3, a beam measurement reporting procedure based on a hierachical architecture is taken as an example, and a second method (a CSI-RS resource set, which is determined as the target reference signal resource and associated with a first reference signal through a quasi-co-located QCL) is described as an example.

First, the base station configures an SSB resource set { SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, SSB8} by RRC, while the base station configures a CSI-RS resource set associated with this SSB resource set. As shown in fig. 4, a diagram is shown in which SSB3 is associated with a set of CSI-RS resources { CSI-RS4, CSI-RS5, CSI-RS6 }. Wherein, the related reference signals are quasi co-located QCL. The QCL-type D RS of each CSI-RS resource in the set of CSI-RS resources is the same SSB signal. For example, QCL-type D RS in the 8 CSI-RS resources { CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4, CSI-RS5, CSI-RS6, CSI-RS7, CSI-RS8} contained in CSI-RS resource set 1 are SSB 1.

Specifically, the beam measurement reporting may include the following steps:

in step 31, the base station triggers beam measurements.

Specifically, the base station configures a trigger state (CSI aperiodicity trigger state) of the channel state information aperiodic and SSB measurement set { SSB1, SSB2, SSB3, SSB4}. And in the nth time slot, the base station issues DCI1, and the terminal is triggered to measure and report the SSB resource set.

And 32, the terminal carries out beam measurement reporting according to the indication of the base station.

Specifically, the terminal measures Layer 1Reference Signal Received Power (L1-RSRP for short) of the SSB measurement set { SSB1, SSB2, SSB3, SSB4}, and sorts the measured L1-RSRP values to obtain L1-RSRP1> L1-RSRP3> L1-RSRP2> L1-RSRP4. The terminal reports the maximum and second largest L1-RSRP beams SSB1, SSB3 and corresponding L1-RSRP1, L1-RSRP3 values.

And step 33, the base station selects a beam according to the measurement result reported by the terminal, performs beam indication, and triggers (trigger) fine beam measurement.

The base station receives the report of the terminal, determines that the new beam is the transmitting beam of SSB1, and updates QCL type D source RS contained in TCI-state in beam indication DCI2 by using SSB 1; wherein the QCL type D source RS contained in the TCI-state in DCI2 is indicated by a first bit. Meanwhile, the base station instructs the terminal to perform subsequent aperiodic measurement report through 1 bit (second bit) in the DCI 2.

Wherein, the aperiodic measurement resource (target reference signal resource) is a resource in the CSI-RS resource set 1 associated with the SSB1 previously configured by the base station through RRC. The non-periodic measurement report resource (the resource reported by the beam measurement result) is determined in a predefined mode; for example, the transmission is performed on the latest scheduled PUSCH after the slot where the PDCCH carrying the beam indication DCI1 is located, or on the latest available PUSCH resource, or on a configured scheduled PUSCH resource.

Step 34: and the terminal receives the beam indication DCI2 of the base station and performs ACK feedback on the beam indication.

Step 35: the new beam takes effect.

Step 36: and the terminal reports the beam measurement result according to the indication of the base station.

The terminal receives the CSI-RS resource set 1 by using the wave beam for receiving the SSB1 according to the indication of the base station, and measures the CSI-RS1, the CSI-RS2, the CSI-RS3, the CSI-RS4, the CSI-RS5, the CSI-RS6, the CSI-RS7 and the CSI-RS8 contained in the resource set to obtain the corresponding L1-RSRP which is ordered from large to small: L1-RSRP2, L1-RSRP3, L1-RSRP5, L1-RSRP1, L1-RSRP4, L1-RSRP7, L1-RSRP8 and L1-RSRP6.

The terminal reports the beam CRI2+ L1-RSRP2 according to a predefined resource indication, such as the latest scheduled PUSCH after the time slot in which the PDCCH carrying the beam indication DCI is located. And the base station receives the report of the terminal, and transmits the PDCCH/PDSCH by using the wave beam for transmitting the CSI-RS in the subsequent downlink transmission.

Example 3: take the case that the base station transmits the beam measurement indication information through different signaling when transmitting the beam indication signaling as an example. The method can specifically comprise the following steps:

step one, a base station configures the following resources:

the CSI-RS resource set 1 is { CSI-RS1, CSI-RS2, CSI-RS3 and CSI-RS4};

the CSI-RS resource set 2 comprises { CSI-RS5, CSI-RS6, CSI-RS7 and CSI-RS8};

CSI-RS resource set 3: { CSI-RS9, CSI-RS10, CSI-RS11, CSI-RS12}.

The CSI measurement resource and the CSI aperiodically triggered State (CSI aperiodically Trigger State) of the CSI are CSI-RS resource sets 1.

And step two, in the nth time slot, the base station issues DCI1, and the trigger terminal performs measurement reporting on the CSI-RS resource set 1.

And step two, the terminal measures the L1-RSRP of the CSI-RS1, the CSI-RS2, the CSI-RS3 and the CSI-RS4 according to the indication of the base station and sequences the obtained L1-RSRP measurement values to obtain L1-RSRP1> L1-RSRP2> L1-RSRP4> L1-RSRP3.

And step three, the terminal reports the largest and second largest L1-RSRP wave beams CSI-RS1 and CSI-RS2 and the corresponding L1-RSRP1 and L1-RSRP2.

Step four, the base station receives the report of the terminal, determines that the new wave beam is the sending wave beam of the CSI-RS1, and uses the CSI-RS1 to update the qcl-type D source RS contained in the TCI-state in the wave beam indication DCI 2; a base station issues a beam indication DCI2, and simultaneously issues an independent uplink DCI3 to trigger aperiodic measurement reporting; the uplink DCI3 for triggering the aperiodic measurement report is a DCI triggering CSI report first in the same time window (for example, M =2 time slots) as the DCI2 indicated by the beam.

And step five, the terminal decodes the DCI2 indicated by the beam, and the terminal receives and decodes the DCI3 triggering CSI reporting at the first time (M =2 time slots) in the same time window by using the beam indicated by the DCI 2.

Step six, the terminal performs HARQ/ACK feedback on the beam indication of the DCI2, and in the resource indicated by the DCI 3: and measuring on CSI-RS resources { CSI-RS9, CSI-RS10, CSI-RS11 and CSI-RS12} which have the same QCL-type D RS as the CSI-RS1 to obtain corresponding L1-RSRP which is sequenced from large to small: L1-RSRP10, L1-RSRP12, L1-RSRP11, L1-RSRP9.

The terminal reports the measurement result on the PUSCH resources indicated in DCI 3.

And step seven, the base station receives the report of the terminal, and transmits the PDCCH/PDSCH by using the wave beam for transmitting the CSI-RS10 in the subsequent downlink transmission.

As shown in fig. 5, an embodiment of the present application provides a beam indication method, which is applied to a base station, and includes:

step S201, a target beam indicated by a first bit of a first signaling and used for receiving is sent to a terminal, and beam measurement indication information of the target beam indicated by a second bit of the first signaling is sent to the terminal; or, when a target beam for reception is indicated to the terminal through the first signaling, beam measurement indication information of the target beam indicated through a second signaling is sent to the terminal.

In this step, specifically, the first signaling is a DCI signaling or a media access control unit MAC-CE; the second signaling is DCI signaling; and the beam measurement indication information is used for triggering the terminal to carry out beam measurement and report on the target beam.

For example, the base station issues DCI1 for beam indication, a first bit of DCI1 includes a Transmission Configuration Indicator (TCI state) state1, a QCL type D RS included in TCI state1 is SSB1, and the terminal instructs the reception/Transmission of a subsequent downlink/uplink signal using a beam for receiving SSB 1. Meanwhile, the base station indicates the terminal to perform subsequent aperiodic measurement reporting through a second bit (for example, 1 bit) in the DCI 1.

For example, the base station issues a beam indication DCI1, and simultaneously issues an independent uplink DCI2 to transmit beam measurement indication information, where the beam measurement indication information is used for a terminal to trigger beam measurement and reporting on a target beam.

In this embodiment, as a manner, a base station indicates, to a terminal, a target beam for reception through a first bit of a first signaling, and indicates, to the terminal, beam measurement indication information of the target beam through a second bit of the first signaling; or as another way, when the base station indicates the target beam for receiving to the terminal through the first signaling, the base station indicates the beam measurement indication information of the target beam to the terminal through the second signaling, so that the terminal reports the measurement result information after measuring the target beam according to the beam measurement indication information. The signaling for triggering the beam measurement is not sent to the terminal after the new beam is generated, so that the processing time of the heatstroke prevention measurement and reporting can be shortened, and the time delay of the beam measurement reporting process is reduced.

Specifically, the second bit is one or more bits in the first signaling.

For example, the second bit in the first signaling may be carried by an existing indication field. For example, "0001" indicates that the terminal performs beam measurement on TCI state 0. "0000" indicates that the terminal does not make beam measurements for TCI state 0. Or, one or more bits in the first signaling may also be carried by an independently defined indication field. For example, a bit "0" indicates that beam measurement is performed on the indicated TCI state, and a bit "1" indicates that beam measurement is not performed on the indicated TCI state.

In an embodiment, the first signaling is associated with the second signaling. In this embodiment, the terminal may quickly decode the second signaling through the first signaling and the association relationship between the first signaling and the second signaling, thereby reducing the processing delay.

Specifically, the first signaling is associated with the second signaling in one of the following two ways:

mode 1): the first signaling comprises an indication domain used for triggering beam measurement, and the first signaling is associated with the second signaling through the indication domain;

for example, when the first signaling and the second signaling are DCI signaling, associating the first signaling with the second signaling may include: the DCI signaling (first signaling) for the beam indication includes a DCI field for triggering beam measurement signaling (second signaling).

Mode 2): the first signaling is associated with the second signaling on a time resource.

In this embodiment, the associated reference signals are the first reference signal and the CSI-RS, the first reference signal and the CSI-RS are associated through quasi-co-location, and when the same beam direction of the associated reference signal is indicated in the first signaling, the first signaling may be used to optimize the receiving beam; when the beam directions indicating the associated reference signals are not the same, it can be used to optimize the transmit beam.

In an embodiment, the method further includes: and indicating resources reported by the beam measurement result of the sink terminal by at least one of the following modes:

mode A1: indicating a latest scheduled Physical Uplink Shared Channel (PUSCH) after a time slot of a Physical Downlink Control Channel (PDCCH) carrying the first signaling as a resource mode A2 for reporting a beam measurement result by the terminal: indicating a latest available PUSCH as a resource for reporting a beam measurement result by the terminal;

mode C: and indicating the configured PUSCH based on the authorized grant base as a resource for reporting the beam measurement result of the terminal.

In an embodiment, when the base station indicates the target beam for receiving to the terminal, the base station further includes: indicating a target reference signal resource used by the terminal for beam measurement by at least one of the following methods:

mode B1:

Mode B2:

indicating the target reference signal resource according to a predefined rule.

Specifically, the predefined rule in the mode B2 specifically includes one of the following:

the 1 st: configuring a set of CSI-RS resources associated with a first reference signal through a quasi co-located QCL; indicating the set of CSI-RS resources as the target reference signal resource; the first reference signal is a quasi co-located QCL type D source reference signal in a TCI state used by the first signaling.

For example, the target reference signal resource may be a resource in a CSI-RS resource set 1 associated with SSB1 configured by the base station through RRC before the base station sends the first signaling, where SSB1 is a target beam indicated in the first signaling.

As shown in fig. 3, a beam measurement reporting procedure based on the hierarchical architecture is taken as an example to describe the determination manner of the second target reference signal resource.

First, the base station configures by RRC the set of SSB resources { SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, SSB8}, while the base station configures the set of CSI-RS resources associated with this set of SSB resources. As shown in fig. 4, a diagram is shown in which SSB3 is associated with a set of CSI-RS resources { CSI-RS4, CSI-RS5, CSI-RS6 }. Wherein, the related reference signals are quasi co-located QCL. The QCL-type D RS of each CSI-RS resource in the set of CSI-RS resources is the same SSB signal. For example, QCL-type D RS in 8 CSI-RS resources { CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4, CSI-RS5, CSI-RS6, CSI-RS7, CSI-RS8} contained in the CSI-RS resource set 1 are SSB 1.

Specifically, the beam measurement reporting may include the following steps:

in step 31, the base station triggers beam measurements.

Specifically, the base station configures a Trigger State (CSI adaptive Trigger State) of Aperiodic channel State information and SSB measurement set { SSB1, SSB2, SSB3, SSB4}. And in the nth time slot, the base station issues the DCI1, and the trigger terminal performs measurement report on the SSB resource set.

And step 32, the terminal carries out beam measurement reporting according to the indication of the base station.

Specifically, the terminal measures Layer 1Reference Signal Received Power (L1-RSRP for short) of the SSB measurement set { SSB1, SSB2, SSB3, SSB4}, and sorts the measured L1-RSRP values to obtain L1-RSRP1> L1-RSRP3> L1-RSRP2> L1-RSRP4. The terminal reports the largest and second largest L1-RSRP beams SSB1, SSB3 and corresponding L1-RSRP1, L1-RSRP3 values.

And step 33, the base station selects a beam and carries out beam indication according to the measurement result reported by the terminal, and the base station triggers (trigger) fine beam measurement.

And the base station receives the report of the terminal, determines that the new beam is the transmitting beam of the SSB1, and updates the QCL type D source RS contained in the TCI-state in the first bit of the beam indication DCI2 by using the SSB 1. Meanwhile, the base station instructs the terminal to perform subsequent aperiodic measurement report through a second bit (for example, 1 bit) in the DCI 2.

Step 35: the new beam takes effect.

And step 36: and the terminal reports the beam measurement result according to the indication of the base station.

The terminal receives the CSI-RS resource set 1 by using the beam for receiving the SSB1 according to the indication of the base station, and measures the CSI-RS1, the CSI-RS2, the CSI-RS3, the CSI-RS4, the CSI-RS5, the CSI-RS6, the CSI-RS7 and the CSI-RS8 contained in the resource set to obtain corresponding L1-RSRP ordered from large to small: L1-RSRP2, L1-RSRP3, L1-RSRP5, L1-RSRP1, L1-RSRP4, L1-RSRP7, L1-RSRP8 and L1-RSRP6.

The 2 nd:

a reference signal resource associating a time domain location with a first resource, indicated as the target reference signal resource; the first resource is a time domain resource where a downlink physical control channel (PDCCH) bearing a first signaling is located;

the first signaling is signaling indicating a target beam for receiving to the terminal by the base station.

For example, a first non-zero power channel state information reference signal Resource Set (NZP-CSI-RS-Resource Set) M time slots after a time slot in which a PDCCH for carrying DCI1 (first signaling) is located is used as a reference signal Resource for beam measurement. The terminal receives and measures reference signals for beam measurement with reception beams of QCL type-D source RS included in the TCI state.

Note that the association described in the mode B2 includes: QCL is between the associated reference signals.
