Technical field

This application relates to the field of communications, and in particular to a method and communication device for updating beams.

Background technique

In the communication process, such as high-frequency communication, network equipment and terminal equipment communicate through directional beams.

Generally speaking, the selection of receiving and transmitting beams of the terminal equipment needs to rely on the beam indication information provided by the network equipment. For example, the network equipment sends a signaling to the terminal equipment, which can indicate the physical uplink control channel of the terminal equipment. channel, PUCCH) resource transmission beam. After receiving the signaling, the terminal device can determine the transmission beam of the PUCCH resource.

In actual communication, there may not be many transmit beams available to the terminal device, such as a few or a dozen. There may even be only two or three transmit beams with better performance. In other words, it is very likely that the transmission beams of multiple resources are the same.

Then, for multiple resources with the same transmission beam, when the transmission beam needs to be updated, how does the terminal device know the updated transmission beam for the multiple resources?

That is, when the terminal device receives the signaling instructing to update the transmission beam of one resource, the terminal device can update the transmission beam and the transmission beams of all resources with the same resource at the same time based on the signaling. In this way, not only the signaling overhead can be saved, but also the flexibility is high. For example, for resources with different transmission beams, the terminal device can still select multiple transmission beams for communication.

Send beam.

Based on the above technical solution, when the transmission beams of multiple resources are the same, the network device can instruct the terminal device to update the transmission beams of the multiple resources through a single signaling. For example, the signaling sent by the network device instructing to update the transmission beams includes The ID of one resource, correspondingly, the terminal device can also update the transmission beams of multiple resources based on one signaling. That is, when the terminal device receives the signaling instructing to update the transmission beam of one resource, the terminal device can update the transmission beam and the transmission beams of all resources with the same resource at the same time based on the signaling. In this way, not only the signaling overhead can be saved, but also the flexibility is high. For example, for resources with different transmission beams, the terminal device can still select multiple transmission beams for communication.

Optionally, the one or more available beams include one transmission beam.

With reference to the second aspect, in some implementations of the second aspect, the indication information is indicated by 1 bit in the third signaling, or the indication information is indicated by the third signaling in the Reserved field indication.

Optionally, the first signaling includes first beam update information of multiple resources, which means that the first signaling is used to activate the same beam for multiple resources. Optionally, the second signaling includes second beam update information for the first resource. In other words, the second signaling includes only the second beam update information for the first resource, which means that the second information Let it be used to activate the beam for the first resource.

Wherein, "only including" is only relative to the first resource and the second resource. In other words, the second signaling includes the beam update information of the first resource but does not include the beam update information of the second resource. It does not limit the second signaling to only include the second beam update information, and may not include other content. For example, the second signaling may also include content such as resource ID.

Based on the above technical solution, after the terminal device updates the transmission beam of the second resource based on the second signaling, the beam update information of the first resource is no longer valid for the second resource. In other words, after receiving the beam update information of the first resource, the terminal device updates the transmission beams of all resources except the second resource (these resources are the same as the transmission beam of the first resource).

detailed description

The technical solution in this application will be described below in conjunction with the drawings.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of this application. The terms used in the description of the application herein are only for the purpose of describing specific embodiments, and are not intended to limit the application.

The embodiments of the present application may be applied to a beam-based communication system, for example, a 5G system or a new radio (NR) system.

To facilitate the understanding of the embodiments of the present application, some terms related to the embodiments of the present application are first introduced below.

1. Beam

A beam is a kind of communication resource, and different beams can be considered as different resources. The embodiment of the beam in the NR protocol can be a spatial domain filter, or a spatial filter, a spatial parameter, or a spatial relation. The beam used to transmit a signal can be called a transmission beam (Tx beam), can be called a spatial domain transmission filter or a spatial transmission parameter (spatial transmission parameter); the beam used to receive a signal can be called To receive the beam (reception beam, Rx beam), it may be called a spatial domain receive filter (spatial domain receive filter) or a spatial receive parameter (spatial RX parameter).

The transmitting beam may refer to the distribution of signal strength in different directions in space after a signal is transmitted through the antenna, and the receiving beam may refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space.

In the embodiments of the present application, the available beams are mentioned many times, and it should be understood that the available beams may include one or more transmit beams, or may include one or more receive beams, which is not limited. In the following embodiments, for ease of description, the usable beams include transmitting beams as examples for exemplification.

In addition, the beam may be a wide beam, or a narrow beam, or other types of beams. The beam forming technology may be beamforming technology or other technology. The beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, or a hybrid digital/analog beamforming technology, etc.

Beams generally correspond to resources. For example, when performing beam measurement, network equipment uses different resources to measure different beams. The terminal equipment feeds back the measured resource quality, and the network equipment knows the quality of the corresponding beam. During data transmission, the beam information is also indicated by its corresponding resource. For example, the network device indicates the PDSCH beam information of the terminal device through the TCI resource in the DCI.

Optionally, multiple beams with the same or similar communication characteristics may be regarded as one beam.

One or more antenna ports can be included in a beam for transmitting data channels, control channels, and sounding signals. One or more antenna ports forming a beam can also be regarded as an antenna port set.

In addition, in beam measurement, each beam of the network device corresponds to a resource, so the resource index can be used to uniquely identify the beam corresponding to the resource.

2. Resources

In beam measurement, the resource index can be used to uniquely identify the beam corresponding to the resource. Resources can refer to uplink signals or downlink signals.

The uplink signal includes, but is not limited to: sounding reference signal (SRS) and demodulation reference signal (DMRS).

Downlink signals include but are not limited to: channel state information reference signal (CSI-RS), cell-specific reference signal (CS-RS), UE-specific reference signal (user equipment specific reference signal, US-RS), demodulation reference signal (demodulation reference signal, DMRS), and synchronization signal/physical broadcast channel block (synchronization signal/physical broadcast channel block, SS/PBCH block). Among them, the SS/PBCH block may be referred to as a synchronization signal block (synchronization signal block, SSB) for short.

The resources can be configured through radio resource control (radio resource control, RRC) signaling.

In terms of configuration structure, a resource is a data structure, including its corresponding uplink/downlink signal related parameters, such as the type of uplink/downlink signal, the resource element that carries the uplink/downlink signal, the transmission time and period of the uplink/downlink signal , The number of ports used to send uplink/downlink signals, etc.

Each uplink/downlink signal resource has a unique index to identify the uplink/downlink signal resource. It is understandable that the index of the resource may also be referred to as the identifier of the resource, which is not limited in the embodiment of the present application.

It should be understood that the resources mentioned in the embodiments of the present application may be downlink signal resources or uplink signal resources.

3. Spatial relation (SR)

The spatial relationship can also be called uplink TCI (uplink TCI, UL TCI). The spatial relationship can be used to determine the transmission beam of the uplink signal. The spatial relationship can be determined by beam training. The reference signal used for beam training may be, for example, an uplink reference signal, such as SRS, or a downlink reference signal, such as SSB or CSI-RS.

During the communication process, the terminal device may determine the transmitting beam based on the spatial relationship indicated by the network device, and the network device may determine the receiving beam based on the same spatial relationship.

In the embodiment of the present application, the sending beam indication can also be replaced with a spatial relation indication or a spatial filter indication. Regarding the receiving beam, in the embodiment of the present application, the receiving beam indication can also be replaced with a QCL indication.

4. Carrier Aggregation (CA)

In order to efficiently use the fragmented spectrum, the system supports aggregation between different carrier components (CC, or carrier components). The technology of aggregating two or more carriers to support a larger transmission bandwidth can be called carrier aggregation. CA includes continuous in-band, discontinuous in-band, discontinuous in-band, etc.

In addition, CA allows PDCCH and PDSCH to be in the same CC or different CCs, that is, cross-carrier scheduling is allowed.

5. Bandwidth part (BWP)

The bandwidth may represent a continuous segment of frequency domain resources, for example, the bandwidth may be BWP. In the embodiments of the present application, "BWP" and "CC" can be used interchangeably. When the difference is not emphasized, the meanings to be expressed are the same.

The BWP may be a group of continuous frequency domain resources on the carrier, and the frequency domain resources that different BWPs can occupy may partially overlap or not overlap each other. Bandwidths of frequency domain resources occupied by different BWPs may be the same or different, which is not limited in this application.

In the embodiment of the present application, different bandwidth parts may correspond to different numerology. The definition of the bandwidth part can refer to the existing technology, such as but not limited to various proposals for NR. With the continuous development of technology, the above definition may also change. The technical solutions of the embodiments of the present application can be applied to 5G systems or New Radio (NR) systems, beam-based communication systems, or beam-based multi-carrier communication systems, etc.

6. Quasi-coordinate

Quasi-colocation: or quasi-co-location (QCL). The colocation relationship can be used to indicate that multiple resources have one or more identical or similar communication features. For multiple resources with a colocation relationship, the same or similar communication configuration can be adopted. For example, if two antenna ports have a co-location relationship, then the large-scale characteristics of the channel transmitting one symbol on one port can be inferred from the large-scale characteristics of the channel transmitting one symbol on the other port. In other words, the signals corresponding to the antenna ports with the QCL relationship have the same parameters, or the parameters of one antenna port can be used to determine the parameters of the other antenna port that has the QCL relationship with the antenna port, or two antenna ports Have the same parameters, or the parameter difference between the two antenna ports is less than a certain threshold. Wherein, the parameter or large-scale characteristic may include one or more of the following: delay spread, Doppler spread, Doppler shift, average delay (average delay) delay), average gain, spatial reception parameters (spatial Rx parameters). Among them, the spatial reception parameters can include one or more of the following: angle of arrival (angle of arrival, AOA), average AOA, AOA extension, angle of departure (angle of departure, AOD), average departure angle AOD, AOD extension, reception Antenna spatial correlation parameters, transmit antenna spatial correlation parameters, transmit beam, receive beam, and resource identification.

7. Spatial QCL

Airspace quasi-parity can be considered a type of QCL. Spatial can be explained from two perspectives: from the sending end or from the receiving end.

From the perspective of the transmitting end, if the two antenna ports are quasi-co-located in the spatial domain, it means that the corresponding beam directions of the two antenna ports are spatially consistent, that is, the spatial filters are the same.

From the perspective of the receiving end, if the two antenna ports are spatially quasi-co-located, it means that the receiving end can receive the signals sent by the two antenna ports in the same beam direction, that is, the receiving parameter QCL is the same.

8. Cell

The cell is described by the higher layer from the perspective of resource management or mobility management or service unit. The coverage of each network device can be divided into one or more serving cells, and the serving cell can be regarded as composed of certain frequency domain resources. In this embodiment of the application, the cell can be replaced with a serving cell or CC. In the embodiments of this application, "cell", "serving cell" and "CC" are used interchangeably. When the difference is not emphasized, the meanings to be expressed are the same. Similarly, "serving cell index", "serving cell ID (ID)", "cell ID" and "CC ID" are used interchangeably. When the difference is not emphasized, what they want to express The meaning is the same.

The communication system applied in the embodiments of the present application may include one or more network devices and one or more terminal devices. A network device can transmit data or control signaling to one or more terminal devices. Alternatively, multiple network devices may simultaneously transmit data or control signaling for one terminal device.

As an example and not a limitation, FIG. 1 is a schematic diagram of a communication system 100 applied in an embodiment of this application. The communication system 100 includes a terminal device 110 and a plurality of network devices 120 (the network device 120a and the network device 120b as shown in FIG. 1). The network device can transmit one or more analog beams simultaneously through one or more radio frequency channels to transmit data to the terminal device. As shown in Figure 1, the network device sends beam 1, beam 2, beam 3, and beam 4 at the same time. For example, network device 120a sends beam 1 and beam 2, and network device 120b sends beam 3 and beam 4, beam 1, beam 2, Both beam 3 and beam 4 can be used to transmit data to the terminal device 110.

As mentioned above, the terminal device's selection of receiving and transmitting beams depends on the network device to provide beam indication information.

Network equipment can use signaling, such as high-level signaling (such as radio resource control (RRC), medium access control-control element (MAC-CE)) or physical layer signaling ( The following control information (downlink control information, DCI)) configures one or more available beams for the terminal device. Take the transmit beam as an example. For example, the network device can use the RRC+MAC-CE+DCI method to configure the physical uplink shared channel (PUSCH) beam for the terminal device; another example, the network device can also use the RRC+MAC-CE method as The terminal device is configured with a physical uplink control channel (PUCCH) beam; another example, the network device can also use the RRC+MAC-CE or RRC+DCI method to configure the SRS beam for the terminal device. These beam indication methods are carried out through spatial relations.

The following takes the beam indication mode of PUCCH as an example for exemplary description.

Assuming there are multiple PUCCH resources (PUCCH resources), beam indication can be performed for each PUCCH resource separately.

For example, in high-level signaling (such as RRC), a beam list is configured for all PUCCH resources in a BWP, such as a spatialrelation list. For all PUCCH resources, one or more available beams can be configured by adding and releasing the cell PUCCH-SpatialRelationInfo.

In order to better understand the beam configuration architecture, as an example and not a limitation, the following is the specific format of the beam configuration in the R15 protocol.

For example, for PUCCH resource, one or more available beams can be configured by adding and releasing the information element PUCCH-SpatialRelationInfo. The format can be as follows:

spatialRelationInfoToAddModList SEQUENCE(SIZE(1..maxNrofSpatialRelationInfos)) OF PUCCH-SpatialRelationInfo,

spatialRelationInfoToReleaseList SEQUENCE(SIZE(1..maxNrofSpatialRelationInfos)) OF PUCCH-SpatialRelationInfoId,

...

For another example, control-resource set (CORESET) configuration: For each CORESET, multiple possible beams are configured by adding and releasing TCI state (TCI state).

Exemplarily, for the PDCCH, the network device can configure the TCI state list for the terminal device through the TCI state addition mode list (tci-StatesPDCCH-ToAddList) in the RRC message. The format can be as follows:

tci-StatesPDCCH-ToAddList SEQUENCE(SIZE(1..maxNrofTCI-StatesPDCCH))OFTCI-StateId,

...

Exemplarily, for the PDCCH, the network device can configure the TCI state list for the terminal device through the TCI state release mode list (tci-StatesPDCCH-ToReleaseList) in the RRC message. The format can be as follows:

tci-StatesPDCCH-ToReleaseList SEQUENCE(SIZE(1..maxNrofTCI-StatesPDCCH))OFTCI-StateId,

...

For another example, CSI-RS configuration: For all CSI-RS resources, multiple possible beams are configured by adding and releasing TCI-State.

Exemplarily, the network device can configure the TCI state list for the terminal device through the TCI state addition mode list (tci-StatesToAddModList) in the RRC message. The format can be as follows:

tci-StatesToAddModList SEQUENCE(SIZE(1..maxNrofTCI-States)) OF TCI-State,

...

Exemplarily, the network device can configure the TCI state list for the terminal device through the TCI state release mode list (tci-StatesToReleaseList) in the RRC message. The format can be as follows:

tci-StatesToReleaseList SEQUENCE(SIZE(1..maxNrofTCI-States)) OF TCI-StateId,

...

For another example, PDSCH TCI configuration: For PDSCH, multiple possible beams are configured by adding and releasing TCI-State.

tci-StatesToAddModList SEQUENCE(SIZE(1..maxNrofTCI-States)) OF TCI-State,

...

tci-StatesToReleaseList SEQUENCE(SIZE(1..maxNrofTCI-States)) OF TCI-StateId,

...

It should be understood that the foregoing is only an exemplary description for ease of understanding, and does not limit the protection scope of the embodiments of the present application.

Network equipment can activate one or more spatial relations through high-level signaling (such as MAC CE signaling). Or it can be understood that, for the PUCCH resource, the network device can indicate the transmission beam of the PUCCH resource by sending the MAC-CE to the terminal device. The following is an example description with reference to FIG. 2.

Fig. 2 is a schematic diagram of the format of MAC CE in the prior art. As shown in the figure, an octet (Oct, octet) in the figure represents a byte composed of 8 bits (bits). The MAC CE includes an identifier (ID) of a serving cell (serving cell), an ID of a BWP, and an indication bit used to indicate whether each beam is activated.

Specifically, Si in the MAC CE is used to indicate whether each beam is activated. Each Si can occupy one bit, and i corresponds to the spatial relationship of PUCCH-SpatialRelationInfoID i in the RRC message above. For example, i is equal to the value of SpatialRelationInfoID, or i can also be the position of the spatial relation list configured by high-level signaling (such as RRC). The value of Si can be 1 or 0, 1 can represent that the beam corresponding to Si is selected and activated, and 0 can represent that the beam corresponding to Si is not selected and activated.

As shown in Figure 2, if the value of S1 is 1, it means that the spatial relationship of PUCCH-SpatialRelationInfoID is 1 or the first one of the spatial relation list configured by RRC is activated, then the terminal device uses the transmission beam indicated by the spatial relationship to send Uplink signal.

It should be understood that FIG. 2 is only an exemplary illustration, and its specific format does not limit the protection scope of the embodiments of the present application.

For example, FIG. 2 shows 8 Si, namely S0 to S7, and the application is not limited thereto. In the embodiment of the present application, for example, more or less Si may be included.

For another example, in FIG. 2, each Si represents one beam as an example for illustration, and the application is not limited thereto. In the embodiment of the present application, for example, S0 to S7 may represent a sequence with a total length of 8 bits, then S0 to S7 may be 256 beams (that is, 2 to the 8th power).

The foregoing description is made by taking the network device as the terminal device instructing the PUCCH transmission beam as an example, and the application is not limited thereto. For example, the network device may also send signaling (such as MAC-CE signaling, RRC signaling, etc.) to the terminal device, and the signaling may be used to send a physical downlink shared channel in the indicated serving cell. PDSCH) Configure the TCI state. For another example, the network device may also send signaling (such as MAC-CE signaling, RRC signaling, etc.) to the terminal device, and the signaling may be used to configure the TCI state for the PUSCH in the indicated serving cell. For another example, the network device can also send signaling (such as MAC-CE signaling, RRC signaling, etc.) to the terminal device, and the signaling can be used to send the physical downlink control channel in the indicated serving cell. , PDCCH) configure the TCI state.

Among them, the activated TCI state indicated by the MAC CE can be understood as: the TCI state configured for the serving cell and BWP indicated by the MAC, that is, when the PDSCH, PUSCH or BWP is transmitted on the BWP in the serving cell In the case of PDCCH, the receiving beam can be determined based on the information indicated by the TCI status.

In some scenarios, for example, the relative positions of the terminal device and the network device have changed, and the network device needs to update the transmission beam of the resource (for example, PUCCH resource) for the terminal device, and send the beam update information to the terminal device.

In the prior art, for each resource that needs to be updated to send a beam, a network device needs to send a MAC-CE signaling to indicate beam information. Taking PUCCH resource as an example, there can be as many as 128 PUCCH resources in R15. For example, when the transmission beams of 128 PUCCH resources need to be updated, the network device needs to send 128 MAC-CE signaling to indicate the update beam.

In addition, in actual communication, there may not be many beams available to the terminal device, such as a few or a dozen. There may even be only two or three beams with better performance. In other words, it is very likely that the transmission beams of multiple resources are the same.

Then, when the transmission beams of multiple resources are the same, and the transmission beams of one resource are the same, the transmission beams of other resources will generally be updated accordingly. If multiple MAC-CEs are sent to update the transmission beam of each resource, the resource is wasted.

In view of this, an embodiment of the present application proposes a method that can reduce the signaling overhead of the beam indicator.

FIG. 3 is a schematic flowchart of a method 300 for updating a beam according to an embodiment of the application. The method 300 may include the following steps.

310. The network device generates and sends first signaling to the terminal device, where the first signaling includes information about one or more available beams of the first resource. Correspondingly, the terminal device receives the first signaling.

Optionally, the first resource may include one or more resources, and the resource may include an uplink signal resource or a downlink signal resource.

For example, the first resource may include one or more PUCCH resources; for another example, the first resource may include one or more SRS resources/SRS resource sets; for another example, the first resource may include one or more PDCCH resources, namely CORESET ; For another example, the first resource may include one or more CSI-RS resources/CSI-RS resource sets; for another example, the first resource may include one or more resources for uplink signals or downlink signals, and so on.

In the following embodiments, for ease of understanding and without loss of generality, the first resource is recorded as resource #1 as an example for illustrative description.

The available beam, for example, may indicate a beam configured by a network device for a terminal device, or may indicate a beam that can be selected by the terminal device to send a beam. As shown in FIG. 2, the available beams may include beams corresponding to S0 to S7 configured by the network device.

The available beams may include one or more transmission beams, in other words, the transmission beams are part or all of the available beams. The transmitting beam refers to the beam used in the communication process, and can also be called the active beam. For example, taking the PUCCH as an example, the sending beam means a sending beam for the terminal device to send an uplink signal to the network device.

The available beams may also include one or more receiving beams, in other words, the receiving beams are part or all of the available beams. The receiving beam refers to the beam used in the communication process, and can also be referred to as the active beam. For example, taking a physical downlink control channel (PDCCH) as an example, the receiving beam refers to the receiving beam when the terminal device receives the downlink signal sent by the network device. The resource receiving beam, for example, may be a PDCCH receiving beam, a physical downlink shared channel (physical downlink shared channel, PDSCH) receiving beam, or a downlink signal (such as CSI-RS) receiving beam, etc.

In the following embodiments, for ease of description, the resource is an uplink signal resource (such as PUCCH resource), and the available beam includes a transmission beam as an example for exemplification. Those skilled in the art should understand that the resources in the following embodiments can all be replaced by downlink signal resources, and the transmission beam can be replaced by the reception beam.

Optionally, the one or more available beams include one transmission beam. The information of one or more available beams, for example, may include the ID of the one or more available beams, and so on. It should be understood that the usable beam may also include multiple transmission beams. For ease of understanding, the following embodiments are all exemplified by taking the usable beam including one transmission beam as an example.

In the embodiments of this application, the activation of the transmission beam is mentioned many times, and those skilled in the art can understand its meaning. It is used to indicate the transmission beam or the transmission beam indication, or it may also indicate the spatial relation indication, in other words, Indicates the transmit beam used during communication. It should be understood that in the embodiments of the present application, the sending beam indication can be replaced with a spatial relation indication or a spatial filter indication.

Optionally, the first signaling may be higher layer signaling, such as MAC-CE signaling and/or RRC signaling. Any signaling that can implement this function belongs to the protection scope of the embodiments of the present application.

Exemplarily, the first signaling is MAC-CE signaling. MAC-CE signaling is used to activate one or more beams (ie, transmit beams) for resource #1. For example, the network device sends MAC-CE signaling to the terminal device, and the MAC-CE signaling includes the transmission beam information of resource #1. After receiving the MAC-CE signaling, the terminal device can determine the transmission beam of resource #1.

Exemplarily, the first signaling is a combination of MAC-CE signaling and RRC signaling. RRC signaling is used to configure the beam list, and MAC-CE signaling is used to activate one or more beams (ie, transmit beams) of resource #1.

Exemplarily, the first signaling is RRC signaling. The beam list configured by the RRC signaling has only one beam, and this beam is also a transmitting beam.

Exemplarily, the first signaling is RRC signaling. The RRC signaling is used to configure the beam list, and by default the first one or more beams in the beam list are transmission beams.

In the following embodiments, for ease of understanding and without loss of generality, the first signaling is marked as signaling #1 as an example for illustrative description.

In any of the following situations, the network device can instruct resource #1 to send beams.

Case 1: One signaling activates multiple transmit beams for one resource.

That is, in case 1, the network device sends signaling #1 to the terminal device, and the signaling #1 is used to indicate the transmission beam of the terminal device resource #1. Correspondingly, after receiving the signaling #1, the terminal device can determine the transmission beam of the resource #1.

For example, taking the resource as PUCCH resource and the signaling as MAC-CE signaling as an example, the network device sends MAC-CE signaling to the terminal device, and the MAC-CE signaling is used to indicate the transmission beam of the terminal device PUCCH resource. Correspondingly, after receiving the MAC-CE signaling, the terminal device can determine the transmission beam of the PUCCH resource.

Case 2: One signaling activates multiple transmission beams for multiple resources.

That is, in case 2, the network device sends signaling #1 to the terminal device, and the signaling #1 is used to indicate the transmission beam of multiple resources of the terminal device, and the multiple resources include resource #1. Correspondingly, after receiving the signaling #1, the terminal device can determine the transmission beams of the multiple resources (including the transmission beams of resource #1).

For example, taking the resource as PUCCH resource and the signaling as MAC-CE signaling as an example, the network device sends MAC-CE signaling to the terminal device, and the MAC-CE signaling is used to instruct the terminal device to transmit beams of multiple PUCCH resources. Correspondingly, after receiving the MAC-CE signaling, the terminal device can determine the transmission beams of the multiple PUCCH resources.

Case 2 can be implemented through multiple solutions, and the implementation of Case 2 is described in detail below.

In any of the above cases, the terminal device can determine the transmission beam of resource #1 according to the received signaling #1.

320. The network device generates and sends second signaling to the terminal device, where the second signaling includes information about one or more available beams of the second resource, where the transmission beam of the first resource and the transmission beam of the second resource are the same. Correspondingly, the terminal device receives the second signaling.

The transmission beam is the same, and those skilled in the art can understand its meaning. For example, the same transmission beam may be embodied as the spatial relation ID is the same or related. Wherein, the spatial relation ID is related, which may be reflected in that the reference signal identifiers in the spatial relation cell are the same or related. The reference signal identification is related, which can be embodied that the uplink signal and the downlink signal are related.

Optionally, the second resource may include one or more resources, and the resource may be an uplink signal resource or a downlink signal resource.

For example, the second resource may include one or more PUCCH resources; for another example, the second resource may include one or more SRS resources/SRS resource sets; for another example, the second resource may include one or more PDCCH resources, namely CORESET ; For another example, the second resource may include one or more CSI-RS resources/CSI-RS resource sets; for another example, the second resource may include one or more uplink signal or downlink signal resources and so on. In the embodiment of the present application, the transmission beam is taken as an example for description, so the second resource here is an uplink signal resource.

In the following embodiments, for ease of understanding and without loss of generality, the second resource is recorded as resource #2 as an example for illustrative description.

As described in step 310, the available beams may include one or more transmit beams, or the available beams may include one or more receive beams. In the embodiments of the present application, the available beam includes one transmission beam as an example for exemplification.

Optionally, the second signaling may be higher layer signaling, such as MAC-CE signaling and/or RRC signaling. Any signaling that can implement this function belongs to the protection scope of the embodiments of the present application. The second signaling is similar to the first signaling. For the second signaling, refer to the description of the first signaling in step 310.

In the following embodiments, for ease of understanding and without loss of generality, the second signaling is marked as signaling #2 as an example for illustrative description.

Similarly, the network device can indicate the transmission beam for resource #2 through any of the above-mentioned case 1 and case 2.

In a possible implementation manner, signaling #1 and signaling #2 may be independent and different signaling (such as MAC-CE signaling), for example, the above case 1. The network device indicates the transmission beam of resource #1 for the terminal device through signaling #1, and the network device indicates the transmission beam of resource #2 for the terminal device through signaling #2.

In a possible implementation manner, signaling #1 and signaling #2 may be the same signaling, such as in one MAC-CE signaling, such as case 2 above. The network device indicates the transmission beams of resource #1 and resource #2 for the terminal device through a signaling.

Step 320 is similar to step 310, and there is no sequence.

330. The network device generates and sends third signaling to the terminal device, where the third signaling includes beam update information of the first resource. Correspondingly, the terminal device receives the third signaling.

In other words, the network device sends the third signaling to the terminal device, and the third signaling includes the beam update information of resource #1. In the embodiment of the present application, after receiving the third signaling, the terminal device can update the transmission beams of resource #1 and resource #2 at the same time. This is described below in conjunction with step 340.

When the sending beam of the resource needs to be updated, the network device sends a signaling to the terminal device to indicate beam update information. If the transmission beams of multiple resources are the same, when the transmission beam of one of the resources is the same, the other transmission beam will generally be updated accordingly.

Take four PUCCH resources as an example for illustrative description, for example, they are respectively recorded as PUCCH resource#1, PUCCH resource#2, PUCCH resource#3, and PUCCH resource#4, and PUCCH resource#1 and PUCCH resource#2 are currently sent The beams are the same. Then when the transmission beam of PUCCH resource#1 is updated, the transmission beam of PUCCH resource#2 is also updated accordingly; or when the transmission beam of PUCCH resource#2 is updated, the transmission beam of PUCCH resource#1 is also updated accordingly .

Optionally, the third signaling may be higher layer signaling, such as MAC-CE signaling. Any signaling that can implement this function belongs to the protection scope of the embodiments of the present application.

In the following embodiments, for ease of understanding and no loss of generality, the third signaling is marked as signaling #3 as an example for illustrative description.

In a possible implementation, the format of signaling #3 is the same as that of signaling #2 or signaling #1. For example, the MAC-CE signaling shown in FIG. 2 will not be repeated here.

In a possible implementation, the format of signaling #3 is different from the format of signaling #2 or signaling #1. The following describes step 340.

It should be understood that the beam update information is only a naming and does not limit the protection scope of the embodiments of the present application.

340. Based on the beam update information of the first resource, the terminal device updates the transmission beam of the second resource. In other words, based on the beam update information of resource #1, the terminal device updates the transmission beam of resource #2.

In other words, after receiving signaling #3, the terminal device not only updates the transmission beam of resource #1, but also updates the transmission beam of resource #2.

Optionally, signaling #3 includes indication information, and the indication information is used to instruct the terminal device to update the transmission beam of resource #2 based on the beam update information of resource #1. Wherein, the indication information may be an implicit indication or a display indication.

After receiving the signaling #3, the terminal device can implement the update resource #2 transmission beam based on any of the following methods.

Method 1: The protocol predefines such rules.

That is to say, no matter how the transmission beams of the current resource #1 and resource #2 are configured, after the terminal device receives the signaling instructing to update the beam, it defaults to update the transmission beams of the same resource as the transmission beam.

Taking resource #1 and resource #2 as examples, for example, the terminal device receives signaling #3, and signaling #3 includes beam update information of resource #1. After receiving signaling #3, the terminal device not only updates the transmission beam of resource #1, but also updates the transmission beam of resource #2. For another example, the terminal device receives signaling #3, and signaling #3 includes beam update information of resource #2. After receiving signaling #3, the terminal device not only updates the transmission beam of resource #2, but also updates the transmission beam of resource #1.

It should be understood that the foregoing description only takes resource #1 and resource #2 as examples, and the application is not limited thereto. After the terminal device receives the signaling #3, the signaling #3 includes the beam update information of any one of the multiple resources with the same transmission beam. The terminal device can update the transmission beam of each of the multiple resources based on the signaling #3.

In method 1, signaling #3 can be the same as existing MAC-CE signaling (such as R15 MAC-CE signaling).

Method 2: Use an existing or newly added field in the signaling, and the length of the field may be, for example, 1 bit.

Using signaling #3 as the MAC-CE signaling, any R field in the MAC-CE signaling can be used. In other words, the network device can indicate whether the terminal device wants to update the transmission beams of all resources with the same transmission beam through the reserved field in the MAC-CE signaling. Alternatively, the network device may indicate whether the terminal device wants to update the transmission beams of all resources with the same transmission beam through a 1-bit field in the MAC-CE signaling.

Take the resource as PUCCH resource, signaling #3 as MAC-CE signaling, and the reserved R field as an example. Assume that the MAC-CE signaling includes a PUCCH resource ID. For example, when R=0, the MAC-CE signaling only updates the transmission beam of the PUCCH resource identified by the PUCCH resource ID; when R=1, this MAC-CE signaling updates the transmission beam of the PUCCH resource identified by the PUCCH resource ID And the transmission beams of other PUCCH resources that are the same as the PUCCH resource ID transmission beam.

Take resource #1 and resource #2 as examples for specific description.

In step 330, the terminal device receives the MAC-CE signaling, and the MAC-CE signaling includes the beam update information of resource #1. When R=0 in the MAC-CE signaling, the MAC-CE signaling only updates the transmission beam of the resource #1; when R=1 in the MAC-CE signaling, the MAC-CE signaling Update the transmission beams of the resource #1 and resource #2.

Method 3: Introduce new MAC-CE signaling.

This application does not limit the format of the new MAC-CE signaling. For example, the MAC-CE signaling may include the same content as the existing MAC-CE signaling: CC ID, BWP ID, PUCCH resource ID, Spatial relation activation information. Different from the existing MAC-CE signaling, the new MAC-CE signaling can use the logical channel identifier (LCID) in the MAC-CE signaling to identify the new MAC-CE signaling. The function of the order. In other words, after the terminal device receives the MAC-CE signaling of this ID, it can learn that the MAC-CE signaling is used to indicate the update of the transmission beam for all resources with the same transmission beam.

Method 4: Based on any one of the several implementation methods in the case 2 above.

In case 2, the network device sends a signaling to the terminal device, and the signaling is used to instruct the terminal device to update the transmission beam of multiple resources, and the multiple resources include resource #1 and resource #2. Correspondingly, after receiving the signaling, the terminal device can determine the transmission beams of the multiple resources.

In other words, the several implementation manners in case 2 are also applicable to the scenario of updating the beam. This is described in detail below.

Therefore, based on the above technical solution, the updated transmission beam can be indicated by using the same resource as the transmission beam as a unit. In other words, the network device instructs the terminal device to update the transmission beams of multiple resources with the same transmission beam through a signaling. This not only saves overhead, but also the terminal device can still have multiple beam selections, so it is more flexible.

Optionally, before step 310, the method 300 may further include step 301.

301. The network device configures a beam list of resources.

The network device can configure the resource beam list through any of the following implementations.

Implementation method A uses the same method as the prior art.

Taking the resource as the PUCCH resource as an example, as mentioned above, a spatial relation list (that is, a transmission beam list) is configured for all PUCCH resources in each BWP in high-level signaling (such as in RRC).

The RRC configuration can be sent through the PDSCH. According to the size of the configuration information, it may be divided into one or more transport blocks (TB) and sent in one or more time units (such as time slots (slot)). There is no restriction on this.

Implementation method B is to configure a transmission beam list for a terminal device.

In other words, the network device configures the sending beam list with the terminal device as a unit. The network device configures a transmission beam list for the terminal device, and the transmission beam list may be applicable to multiple CCs of the terminal device.

Implementation C, configure a transmit beam list for one CC.

In other words, the network device is configured to send the beam list in units of CC. For one CC, the network device configures a transmission beam list, and the transmission beam list may be applicable to multiple BWPs of one CC of the terminal device. For example, if there are 4 BWPs in one CC of the terminal device, the transmission beam list of this configuration can be applied to the 4 BWPs.

Implementation method D, configure the cell-level transmit beam list.

In other words, the network device configures the sending beam list in a cell. The network device configures a transmission beam list for the cell, and the transmission beam list may be applicable to all terminal devices in the cell.

The foregoing exemplarily introduces four implementation manners, and the embodiments of the present application are not limited thereto. The embodiment of the present application does not limit the specific configuration method of the beam list of the network device configuration resource.

The following takes the signaling as MAC-CE signaling and the PUCCH resource as an example to describe the implementation of Case 2 in detail.

Case 2 includes at least one or more of the following implementation methods.

Implementation mode 1: PUCCH resource ID in MAC-CE signaling is replaced with PUCCH resource set ID (PUCCH resource set ID).

The PUCCH resource set may include multiple PUCCH resources. After receiving the MAC-CE signaling, the terminal device determines the transmission beams of all PUCCH resources belonging to the PUCCH resource set (that is, the multiple PUCCH resources). Or, after receiving the MAC-CE signaling, the terminal device determines to update the transmission beams of all PUCCH resources (that is, the multiple PUCCH resources) belonging to the PUCCH resource set.

As shown in Figure 4, the MAC-CE signaling includes PUCCH resource set ID. Assuming that S2 is 1, after receiving the MAC-CE signaling, the terminal device determines that the transmission beams of all PUCCH resources (that is, the multiple PUCCH resources) belonging to the PUCCH resource set are beams corresponding to S2. Or, the terminal device determines that all PUCCH resources belonging to the PUCCH resource set (that is, the multiple PUCCH resources) updated transmission beams are beams corresponding to S2.

Implementation mode 2, PUCCH resource ID of MAC-CE signaling is replaced with PUCCH resource group ID (PUCCH resource group ID).

The PUCCH resource group may include multiple PUCCH resources. After receiving the MAC-CE signaling, the terminal device determines the transmission beams of all PUCCH resources belonging to the PUCCH resource group (that is, the multiple PUCCH resources). Or, after receiving the MAC-CE signaling, the terminal device determines to update the transmission beams of all PUCCH resources (that is, the multiple PUCCH resources) belonging to the PUCCH resource group.

As shown in Figure 5, the MAC-CE signaling includes PUCCH resource group ID. Assuming that S2 is 1, after receiving the MAC-CE, the terminal device determines that the transmission beams of all PUCCH resources (that is, the multiple PUCCH resources) belonging to the PUCCH resource group are beams corresponding to S2. Alternatively, the terminal device determines that all PUCCH resources belonging to the PUCCH resource group (that is, the multiple PUCCH resources) updated transmission beams are beams corresponding to S2.

Implementation mode 3, the PUCCH resource ID in the MAC-CE signaling is replaced with multiple PUCCH resource IDs.

As shown in Figure 6, the MAC-CE signaling includes multiple PUCCH resource IDs, such as PUCCH resource 1, PUCCH resource 2, ... in Figure 6. Assuming that S2 is 1, after receiving the MAC-CE, the terminal device determines that the transmission beams belonging to the multiple PUCCH resources are the beams corresponding to S2. Alternatively, the terminal device determines that the updated transmission beam belonging to the multiple PUCCH resources is the beam corresponding to S2.

Implementation manner 4, the MAC-CE signaling does not include specific PUCCH resource ID, including CC or BWP information, and the MAC-CE signaling is used to instruct the PUCCH to send beam indication information.

As shown in Figure 7, the MAC-CE signaling includes serving cell ID and BWP ID, and does not include PUCCH resource ID. Assuming that S2 is 1, after receiving the MAC-CE, the terminal device determines that the transmission beams of all PUCCH resources belonging to the serving cell ID and BWP ID are beams corresponding to S2. Or, the terminal device determines that the updated transmission beams of all PUCCH resources belonging to the serving cell ID and BWP ID are the beams corresponding to S2.

That is to say, in the implementation manner 4, the MAC-CE signaling may indicate transmission beams for all PUCCH resources in the CC or BWP.

In the implementation manner 4, the indication information can be displayed and carried in the MAC-CE, or the function of the MAC-CE can be identified by a logical channel identifier (logical channel identifier, LCID) in the MAC-CE. In other words, when the terminal device receives the MAC-CE with this ID, it can learn that the MAC-CE indicates the sending beam for all PUCCH resources in the CC or BWP.

It should be understood that in some of the foregoing embodiments, PUCCH resource is taken as an example for exemplification, and this application is not limited thereto. For example, the foregoing PUCCH resource can be replaced with other uplink signal resources and so on.

It should also be understood that the foregoing embodiment uses the transmission beam as an example for description, and this application is not limited to this. For example, the resource in the foregoing embodiment can be replaced with a downlink signal resource, and the transmission beam can be replaced with a reception beam. In this case, The received beam indication can be replaced with QCL indication.

It should also be understood that, in the foregoing embodiment, the sending beam indication can be replaced with a spatial relation indication, or the sending beam indication can be replaced with a spatial filter indication.

Based on the above technical solution, when the transmission beams of multiple resources are the same, the network device can instruct the terminal device to update the transmission beams of multiple resources through a single signaling. Accordingly, the terminal device can also update multiple transmission beams based on one signaling. The transmission beam of the resource. In this way, not only the signaling overhead can be saved, but also the flexibility is high. For example, for resources with different transmission beams, the terminal device can still select multiple transmission beams for communication.

FIG. 8 is a schematic flowchart of a method 400 for updating beams according to an embodiment of this application. The method 400 may include the following steps.

410. The network device sends signaling #A to the terminal device, where the signaling #A is used to activate the same transmission beam for multiple resources. Correspondingly, the terminal device receives the signaling #A, and based on the signaling #A, the transmission beams of multiple resources can be determined.

In other words, the signaling #A is used to activate beams for multiple resources, that is, the signaling #A includes information about one or more available beams of the multiple resources, and the available beams include one or more transmission beams. .

For the description of the transmit beam, refer to the description in the method 300, and details are not repeated here. It should be understood that the embodiments of the present application are not limited thereto. The transmitting beam can be replaced with a receiving beam, and the corresponding resources can be replaced with downlink signal resources.

Taking the PUCCH resource as an example, the network device activates transmission beams for multiple PUCCH resources. That is, the network device sends signaling to the terminal device, and the signaling includes beam update information for multiple PUCCH resources. After receiving the signaling, the terminal device can determine the multiple PUCCH resources based on the signaling. Send beam.

The signaling #A may be high-level signaling, such as MAC-CE signaling. Any signaling that can implement this function belongs to the protection scope of the embodiments of the present application.

It should be understood that the signaling #A in the method 400 is similar to the signaling #3 in the method 300. For details, reference may be made to the description of the foregoing method 300, which will not be repeated here.

It should be understood that, for ease of understanding and without loss of generality, signaling #A is taken as an example for illustration. The signaling #A is only a naming, and does not limit the protection scope of the embodiments of the present application. For example, the signaling #A can also become R16 signaling.

The network device may activate transmission beams for multiple PUCCH resources through any one of the implementation manners in the case 2 in the above method 300. The following takes MAC-CE signaling as an example to briefly describe multiple implementation methods.

Implementation method 1, PUCCH resource ID in MAC-CE signaling is replaced with PUCCH resource set ID.

For example, as shown in Figure 4, the signaling #A sent by the network device to the terminal device includes the PUCCH resource set ID. Signaling #A can be used to indicate the transmission beams of all PUCCH resources belonging to the PUCCH resource set ID.

Implementation mode 2, PUCCH resource ID in MAC-CE signaling is replaced with PUCCH resource group ID.

For example, as shown in Figure 5, the signaling #A sent by the network device to the terminal device includes the PUCCH resource group ID. Signaling #A is used to indicate the transmission beams of all PUCCH resources belonging to the PUCCH resource group ID.

For example, as shown in Figure 6, the signaling #A sent by the network device to the terminal device includes multiple PUCCH resource IDs. The signaling #A may be used to indicate the transmission beams of multiple PUCCH resources corresponding to the multiple PUCCH resource IDs.

Implementation manner 4, the MAC-CE signaling does not include specific PUCCH resource ID, including CC or BWP information, and the MAC-CE is used to instruct the PUCCH to send beam indication information.

For example, as shown in Figure 7, the signaling #A sent by the network device to the terminal device includes serving cell ID and BWP ID, but does not include PUCCH resource ID. Signaling #A can be used to indicate the transmission beams of all PUCCH resources belonging to the serving cell ID and BWP ID.

420. The network device sends signaling #B to the terminal device, where the signaling #B is used to update the sending beam for a certain resource. Accordingly, the terminal device receives signaling #B.

In other words, the signaling #B is used to activate a beam for a certain resource, that is, the signaling #B includes information about available beams of a resource, and the available beams include one or more transmission beams.

The network device can update the transmission beam for a certain resource through signaling #B. For distinction, the resource indicated by signaling #B is recorded as resource #B.

The signaling #B may be high-level signaling, such as MAC-CE signaling and/or RRC signaling. Any signaling that can implement this function belongs to the protection scope of the embodiments of the present application. Signaling #B is similar to signaling #1 or signaling #2 in method 300, and signaling #B can refer to the description of signaling #1 in step 310.

It should be understood that, for ease of understanding and without loss of generality, signaling #B is taken as an example for illustration. Signaling #B is only a naming, and does not limit the protection scope of the embodiments of the present application. For example, signaling #B can also become R15 signaling.

Step 420 and step 410 have no sequence.

After receiving the signaling #B, the terminal device can update the transmission beam of the resource #B.

430. The terminal device updates the transmission beam of resource #B.

Assuming that resource #B belongs to one of the multiple resources in step 420, the transmission beam indicated by signaling #A may be different from the transmission beam indicated by signaling #B. In this case, at least the following two cases are included.

Case A: The terminal device determines the transmission beam of resource #B based on one of the signaling. In other words, for the transmission beam of resource #B, there is only one active spatialrelation at a time.

For case A, the terminal device can determine the transmission beam of resource #B based on any of the following methods.

Manner 1: The terminal device determines the transmission beam of resource #B based on signaling #B.

That is to say, through pre-regulation, when signaling #A and signaling #B appear at the same time, the terminal device determines the transmission beam of resource #B based on signaling #B. For example, if the signaling #A received by the terminal device indicates that the transmission beam of resource #B is beam 1, and the signaling #B received by the terminal device indicates that the transmission beam of resource #B is beam 2, the terminal device determines that the transmission beam of resource #B The transmit beam is beam 2.

Manner 2: The terminal device determines the transmission beam of resource #B based on the priority rule.

The priority rule may be stipulated in the protocol, or a rule set in advance, or it may be notified to the terminal device by the network device, and there is no strict limitation on this.

Exemplarily, the priority rule may be: UE level<CC level<BWP level<resource set level (e.g. PUCCH resource set level)<resource group level (e.g. PUCCH resource group level)<resource level (e.g. PUCCH resource level). This approach can increase flexibility.

For example, the UE level may indicate a transmission beam indicating all resources belonging to the UE.

Assume that the signaling #A received by the terminal device indicates that the transmission beam of the UE is beam 1. In other words, the signaling #A indicates that the transmission beam of all resources of the UE is beam 1, and the signaling # received by the terminal device B indicates that the transmission beam of resource #B is beam 2, and the UE-level priority is lower than the resource-level priority, so the terminal device determines that the transmission beam of resource #B is beam 2.

For another example, the resource group level may indicate a transmission beam indicating all resources belonging to the resource group.

Assume that the signaling #A received by the terminal device indicates that the transmission beam of the resource group is beam 1. In other words, the signaling #A indicates that the transmission beam of all resources belonging to the resource group is beam 1, and the terminal device receives Signaling #B indicates that the transmission beam of resource #B is beam 2. Then, according to the priority of the resource group level lower than the priority of the resource level, the terminal device determines that the transmission beam of resource #B is beam 2.

For another example, the CC level may indicate a transmission beam indicating all resources belonging to the CC level.

Assume that the signaling #A received by the terminal device indicates that the transmission beam of the CC is beam 1. In other words, the signaling #A indicates that the transmission beam of all resources belonging to the CC is beam 1, and the signaling received by the terminal device #B indicates resource #B's transmission beam is beam 2, and then according to the priority of the CC level lower than the priority of the resource level, the terminal device determines that the transmission beam of resource #B is beam 2.

Exemplarily, the priority rule may be: multiple resources>single resource. For example, UE level>CC level>BWP level>resource set level (for example, PUCCH resource set level)>resource group level (for example, PUCCH resource group level)>resource level (for example, PUCCH resource level). This way can reduce signaling overhead, and can reduce time delay.

For example, the BWP level may indicate a transmission beam indicating all resources belonging to the BWP.

Assume that the signaling #A received by the terminal device indicates that the transmission beam of the BWP is beam 1. In other words, the signaling #A indicates that the transmission beam of all resources of the BWP is beam 1, and the signaling # received by the terminal device B indicates that the transmission beam of resource #B is beam 2, and the priority of multiple resources is higher than the priority of a single resource, so the terminal device determines that the transmission beam of resource #B is beam 1.

For another example, the resource set level may indicate a transmission beam indicating all resources belonging to the resource set.

Assume that the signaling #A received by the terminal device indicates that the transmission beam of the resource set is beam 1. In other words, the signaling #A indicates that the transmission beam of all resources belonging to the resource set is beam 1, and the terminal device receives Signaling #B indicates that the transmission beam of resource #B is beam 2. Then, according to the priority of multiple resources higher than the priority of a single resource, the terminal device determines that the transmission beam of resource #B is beam 2.

Exemplarily, the priority rule may be: signaling #B <signaling #A

That is, when signaling #A (for example, R16 signaling) and signaling #B (for example, R15 signaling) occur simultaneously, the terminal device determines the transmission beam of resource #B based on signaling #B.

Manner 3: The terminal device determines the transmission beam of resource #B based on the order of receiving the signaling.

Exemplarily, the terminal device may determine the transmission beam of resource #B based on the first received signaling.

For example, the terminal device first receives signaling #A, and signaling #A indicates that the transmission beam of resource #B is beam 1, then the terminal device receives signaling #B, and signaling #B indicates the transmission beam of resource #B If it is beam 2, the terminal device determines that the transmission beam of resource #B is beam 2.

Exemplarily, the terminal device may determine the transmission beam of resource #B based on the most recently received signaling.

For example, the terminal device first receives signaling #A, and signaling #A indicates that the transmission beam of resource #B is beam 1, then the terminal device receives signaling #B, and signaling #B indicates the transmission beam of resource #B If it is beam 2, the terminal device determines that the transmission beam of resource #B is beam 1.

Case B: The terminal device determines the transmission beam of resource #B based on signaling #A and signaling B. In other words, for the transmission beam of resource #B, there can be multiple active spatial relations at a time.

For example, the terminal device receives signaling #A and signaling #B, and signaling #A indicates that the transmission beam of resource #B is beam 1, and signaling #B indicates that the transmission beam of resource #B is beam 2, then the terminal device The transmission beams for determining resource #B include beam 1 and beam 2.

Optionally, the method 400 may further include 440.

440. The network device sends a signaling #C to the terminal device, where the signaling #C is used to send beams for multiple resource updates. Correspondingly, the terminal device receives the signaling #C, and based on the signaling #C, the transmission beams of multiple resources can be updated.

In other words, the signaling #C includes beam update information of multiple resources.

The signaling #C may be high-level signaling, such as MAC-CE signaling. Any signaling that can implement this function belongs to the protection scope of the embodiments of the present application.

It should be understood that the signaling #C is only a naming and does not limit the protection scope of the embodiments of the present application. For example, the signaling #C can also become R16 signaling.

The network device may update transmission beams for the multiple resources through any one of the implementation manners in step 410. I won't repeat them here.

Optionally, the transmission beam of resource #B updated by signaling #B in step 430 is no longer updated by signaling #C.

That is to say, assuming that in step 430, the terminal device updates the transmission beam of resource #B based on signaling #B, then after receiving signaling #C, the terminal device only updates the resources except resource #B among multiple resources. The transmission beam is not updated for resource #B.

Optionally, the transmission beam of the resource #B updated by the signaling #B in step 430 is determined according to the indication information in the signaling #C whether to be updated by the signaling #C.

That is to say, assuming that in step 430, the terminal device updates the transmission beam of resource #B based on signaling #B, then after receiving signaling #C, the terminal device determines whether to use the indication information in signaling #C. Update the transmission beam of resource #B.

The network device may use an existing or newly added field in the signaling to indicate whether the terminal device updates the transmission beam of the resource, and the length of the field may be, for example, 1 bit. Taking the signaling #C as the MAC-CE signaling as an example, any R field in the MAC-CE signaling can be used to indicate whether the transmission beam of the resource #B is updated by the signaling #C.

For example, the terminal device receives MAC-CE signaling, and when R=0 in the MAC-CE signaling, the MAC-CE signaling instructs to update the transmission beams of the multiple resources (including resource #B); When R=1 in the MAC-CE signaling, the MAC-CE signaling instructs to update the transmission beam of resources other than resource #B among the multiple resources.

Optionally, the method 400 may further include 401.

401: The network device configures a beam list of resources.

Optionally, the resources may include uplink signal resources and may also include downlink signal resources.

For example, the resource may include one or more PUCCH resources; for another example, the resource may include one or more SRS resource/SRS resource set; for another example, the resource may include one or more PDCCH resources, namely CORESET; another example , The resource may include one or more CSI-RS resource/CSI-RS resource set; for another example, the resource may include one or more uplink signal or downlink signal resources and so on.

Step 401 is similar to step 301, which is concise here and will not be repeated here.

It should be understood that, in some of the above embodiments, resource #B in multiple resources is taken as an example for description, but this does not limit the application. The related description of resource #B in this article can be applied to multiple resources. Every resource.

It should also be understood that in some of the foregoing embodiments, PUCCH resource is taken as an example for exemplification, and the application is not limited thereto. For example, the foregoing PUCCH resource can be replaced with other uplink signal resources and so on.

Based on the above technical solution, when the transmission beams of multiple resources are the same, the network device can instruct the terminal device to update the transmission beams of the multiple resources through a single signaling. Accordingly, the terminal device can also update multiple transmission beams based on one signaling. The transmission beam of resources can save signaling overhead. In addition, when multiple beam indications have conflicts, for example, when the above-mentioned signaling #A and signaling #B appear at the same time, the conflict can be avoided through a pre-defined priority rule or a default rule.
