Description

Method and apparatus for indicating spatial relationship information

technical field

The present disclosure relates to the field of communications, and more particularly to methods and devices for indicating spatial relationship information.

background

In New Radio (NR) 3GPP Specification Release 15, beam indication is done on a per Physical Uplink Control Channel (PUCCH) resource basis. For a given bandwidth part (BWP) in a serving cell, a terminal device may be configured with 4 sets of PUCCH resources, and in each set of PUCCH resources, the terminal device may be configured with one or more PUCCH resources. For transmission on each PUCCH resource, the terminal device is configured with spatial relationship information that may include one or more reference signal resource IDs, such as the parameter PUCCH-spatialRelationInfo. Each of these reference signal resources is used to provide information about which transmission beam is used by the terminal device for transmission on that PUCCH resource. For example, if the reference signal resource is a sounding reference signal (SRS) resource, the terminal device will use the same transmission beam for the SRS resource on transmissions on that PUCCH resource. If the reference signal resource is a Channel State Information Reference Signal (CSI-RS) resource or a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block, the terminal device will use the same The uplink transmit beam corresponding to the receive beam for resource transmission or SS/PBCH block transmission. The base station (eg gNB) can configure only one PUCCH-spatialRelationInfo value to the PUCCH resource, and when the gNB wants to switch the transmission beam of the PUCCH resource, the gNB can reconfigure this parameter. The base station can also configure multiple PUCCH-spatialRelationInfo values to the PUCCH resource in Radio Resource Control (RRC), and then use Medium Access Control (MAC) Control Element (CE) signaling to activate one of those configured PUCCH-spatialRelationInfo values One, as the current transmission beam of the PUCCH resource. If the base station wants to switch the transmission beam of a PUCCH resource, the base station can use a MAC CE message to indicate another PUCCH-spatialRelationInfo value of the PUCCH resource. The base station can use the MAC CE message to indicate the PUCCH-spatialRelationInfo value of each PUCCH resource. The advantage of this method is flexibility, and the base station is allowed to apply different transmission beams on different PUCCH resources. But the disadvantage is MAC CE signaling overhead. In a given BWP, a terminal device may be configured with up to 128 PUCCH resources. In general, all PUCCH resources in the same frequency band may use the same "best" transmission beam for transmission. In order to update the transmission beams of all these PUCCH resources, 128 MAC CE messages need to be transmitted, because the above method only allows beam indication per PUCCH resource. Therefore, new methods for beam indication of PUCCH resources are needed for the purpose of lower signaling overhead.

Fig. 1 shows a schematic diagram of an exemplary application scenario where the implementation of the present disclosure can be applied. The communication system shown in FIG. 1 may include a terminal device 10 and a network device 20 . The network device 20 is configured to provide communication services for the terminal device 10, and is connected to a core network (not shown). The terminal device 10 accesses the network by searching for a synchronization signal or a broadcast signal or the like transmitted by the network device 20 to communicate with the network. The arrows shown in FIG. 1 may indicate uplink/downlink transmissions over the cellular link between the terminal device 10 and the network device 20 .

5G wireless systems are typically multi-beam based systems in frequency range 2 (FR2), where multiple transmit and receive analog beams are used by base stations and/or terminal devices to combat large path losses in high frequency bands. In high-band systems such as millimeter-wave systems, base stations and terminal equipment can be deployed with a large number of antennas, so that large-gain beamforming can be used to overcome large path loss and signal blocking. Due to hardware limitations and costs, base stations and terminal equipment may only be equipped with a limited number of transmit and receive units (TXRU). Therefore, a hybrid beamforming mechanism can be utilized in both the base station and the terminal equipment. In order to obtain the best link quality between the base station and the terminal device, the base station and the terminal device need to align the analog beam direction for a specific downlink or uplink transmission. For downlink transmission, they need to find the best base station transmit beam and end device receive beam pair, while for uplink transmission, they need to find the best end device transmit beam and base station receive beam pair.

For communication between a terminal device and a base station, the base station and the terminal device need to determine which transmit and receive beams are to be used. When a terminal device moves, the beams used by the base station and the terminal device for communication may change. In the 3GPP 5G specification, the functions of beam measurement and reporting, beam indication and beam switching are defined to support such multi-beam based operation.

In the beam measurement and reporting function, the terminal device can measure one or more transmission beams of the base station, and then the terminal device can select the best transmission beam and report its selection to the base station. By measuring the transmit beam of the base station, the terminal device can also measure one or more receive beams and then select the best receive beam for a particular transmit beam of the base station. In this function, the base station can also measure one or more transmission beams of the terminal device, and then select the best transmission beam of the terminal device for uplink transmission. In order to support the measurement of the transmission beam of the base station, the base station can transmit multiple reference signal (RS) resources, and then configure the terminal equipment to measure those RS resources. The terminal device may then report the index of one or more selected RS resources selected based on some measurement metric, eg Layer 1 Reference Signal Received Power (L1-RSRP). To support measurement of a terminal device's transmit beam for uplink transmissions, the base station may configure the terminal device to transmit one or more uplink RS resources (eg, Sounding Reference Signal (SRS) resources), and then the base station may measure those RS resources. The base station can determine which transmit beam of the terminal device is best for uplink transmission based on measurements such as the L1-RSRP of those RS resources.

In the function of beam indication, for downlink transmission, the base station can indicate to the terminal device which transmit beam of the base station is used for transmission, so that the terminal device can use an appropriate receive beam to receive the downlink transmission. For Physical Downlink Control Channel (PDCCH) transmission, the base station may indicate to the terminal equipment an identification (ID) of one transmit beam of the base station. For Physical Downlink Shared Channel (PDSCH) transmission, the base station may use Downlink Control Information (DCI) in the PDCCH to indicate the ID of one transmission beam used to transmit the corresponding PDSCH. For uplink transmissions from a terminal device, the base station may also indicate to the terminal device which transmit beam of the terminal device should be used. For example, for Physical Uplink Control Channel (PUCCH) transmission, the terminal device should use the transmission beam indicated by the base station through the configuration of spatial relation information (eg PUCCH-SpatialRelationInfo). For Sounding Reference Signal (SRS) transmission, the terminal device should use the transmission beam indicated by the base station through the configuration of the spatial relationship information. For Physical Uplink Shared Channel (PUSCH) transmission, the terminal device shall use the transmit beam indicated by the information element contained in the scheduling DCI.

The function of beam switching is used by the base station to switch the transmission beam for downlink or uplink transmission. This function is useful when the transmission beam used for the transmission is currently out of date due to, for example, movement of the terminal device. When the base station finds that the transmission beam currently used for downlink transmission is bad or the base station finds another transmission beam better than the current transmission beam, the base station may send signaling to the terminal device to notify the change of the transmission beam. Similarly, the base station may switch the uplink transmission beams of the terminal devices used to transmit some uplink transmissions.

In communication systems such as New Radio (NR) systems, downlink (DL) signals may include control signaling for transmitting DL Control Information (DCI) over the PDCCH channel, data signals for transmitting information packets over the PDSCH channel, and some types of reference Signal. The DCI may indicate information on how the PDSCH is transmitted, including eg resource allocation and transmission parameters of the PDSCH. The base station can transmit one or more types of reference signals for different purposes, including the demodulation reference signal (DM-RS), which is transmitted with the PDSCH and can be used by the terminal device to demodulate the PDSCH, can be used by the terminal device to Channel State Information Reference Signal (CSI-RS), which measures the CSI of the transmission beam of the base station or the downlink channel between the base station and the terminal equipment, and the Phase Tracking Reference Signal (PT-RS), which is also together with the PDSCH is transmitted and can be used by end devices to estimate the phase noise caused by imperfections in the radio frequency (RF) part of the transmitter and receiver, which is then compensated for when decoding the PDSCH. In NR, DL resource allocation for PDCCH, PDSCH, and reference signals is performed in Orthogonal Frequency Division Multiplexing (OFDM) symbols and in units of Physical Resource Block (PRB) groups. Each PRB contains some eg 12 Resource Elements (REs) in the frequency domain. A transmission bandwidth (BW) of one downlink transmission consists of frequency resource units called resource blocks (RBs), and each RB consists of some, eg 12, subcarriers or REs.

The uplink (UL) signal transmitted by the terminal device to the base station may include a data signal that transmits a data packet through the PUSCH channel, an uplink control signal that transmits UL control information (UCI) that may be transmitted on the PUSCH or PUCCH channel, and an UL reference Signal. The UCI may carry a Scheduling Request (SR) used by the terminal device to request uplink transmission resources, a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) feedback for PDSCH transmission, or a CSI report. A terminal device may transmit one or more types of uplink reference signals for different purposes, including DM-RS transmitted with PUSCH transmission and used by the base station to demodulate PUSCH, also transmitted with PUSCH and transmitted by PT-RS used by the base station to estimate the phase noise caused by imperfections in the RF section, which the base station can then perform on the phase noise when decoding the PUSCH, and used by the base station to measure one or more end-device transmission beams or end-device The SRS signal of the CSI of the uplink channel between the base station and the base station. Similarly, UL resource allocation for PUSCH, PUCCH and UL reference signals is performed in units of OFDM symbols and PRB groups.

The transmission intervals of a DL or UL channel/signal are called slots, each slot contains some eg 14 symbols in the time domain. In the NR system, the duration of one slot may be 1, 0.5, 0.25 or 0.123 milliseconds for subcarrier spacing of 15KHz, 30KHz, 60KHz and 120KHz, respectively. The NR system supports flexible basic parameter sets, and the appropriate DFDM subcarrier spacing can be selected based on deployment scenarios and service requirements. In NR systems, DL and UL transmissions may use different sets of basic parameters.

In the current design, spatial relationship information is updated/indicated per PUCCH resource. In one BWP, a terminal device can be configured with up to 128 PUCCH resources. Therefore, even in a general deployment, most of the PUCCH resources in one BWP may use the same transmission beam, according to the current design base station (e.g. gNB) will have to transmit up to 128 MACCE messages to update the transmission beams of those PUCCH resources , which results in unnecessarily large signaling overhead.

For multiple transmit/receive point (multi-TRP) transmissions, a terminal device may apply different transmission beams on PUCCH resources targeting different TRPs. The design in version 15 supports this. However, unnecessarily large signaling overhead is still a problem here, since all PUCCHs targeting the same TRP usually use the same transmission beam, and the number of TRPs in a multi-TRP transmission is usually not large, eg 2.

In this disclosure, a method and apparatus for indicating spatial relationship information for beam indication of a PUCCH channel are proposed. In this disclosure, a "beam" may correspond to an RS resource, which may be a CSI-RS resource, an SRS resource, an SS/PBCH block, or any other type of RS.

As shown in FIG. 2 , the method for indicating spatial relationship information according to an exemplary implementation of the present disclosure may include actions 210 and 220 .

In action 210, the network device sends an indication of the spatial relationship information to the terminal device.

In action 220, the terminal device applies the spatial relationship information indicated by the network device to the transmission on the plurality of PUCCH resources.

In an exemplary implementation, the spatial relationship information may include at least first spatial relationship information and second spatial relationship information, and the network device may configure first high-level parameters. The value of the first high-level parameter may at least include a first value and a second value, the first spatial relationship information may correspond to the first high-level parameter that is the first value, and the second spatial relationship information may correspond to the first high-level parameter that is the second value. A high-level parameter.

In one exemplary implementation, assume that there are two TRPs in a multi-TRP transmission scenario. Those skilled in the art can understand that there may be another number of TRPs in the multi-TRP transmission scenario, and these two TRPs are only used as examples herein. A terminal device may be configured with a first higher layer parameter, for example called PDCCH group ID, which may take two possible values: a first value and a second value, and the first higher layer parameter may be configured into a control resource set (CORESET ), the CORESET is configured to the terminal device. A first higher layer parameter may be used to identify a TRP in a multi-TRP transmission. Examples of values for higher layer parameters may be 0 or 1. For example, the first value may be 0 and the second value may be 1, or alternatively, the first value may be 1 and the second value may be 0, without limitation in the implementation of the present disclosure. In another example of identifying a TRP by a first high-level parameter, in a configuration of a CORESET, the first high-level parameter may be "yes" or "no", wherein a CORESET with a configuration in which the first high-level parameter is "yes" may be Used by one TRP while a CORESET with a configuration in which the first higher layer parameter is "none" can be used by another TRP. In the implementation of the present disclosure, there is no limit to the specific way of identifying the TRP through the first high-level parameter. For the convenience of description and as an example, in the following exemplary implementation, different values (for example, two values) of the first high-level parameter are used to identify TRP in multi-TRP transmission.

The first spatial relationship information (such as the first PUCCH-SpatialRelationInfo value) with the first high-layer parameter as the first value and the second spatial relationship information (such as the second PUCCH-SpatialRelationInfo value) with the first high-layer parameter as the second value may be indicated to the terminal device. value). Then for the transmission on the PUCCH resource, the terminal device may be requested to select one of the first spatial relationship information and the second spatial relationship information to apply to the transmission on the PUCCH resource based on the UCI report content carried in the transmission.

In an exemplary implementation, the terminal device applying the spatial relationship information to the transmission on multiple PUCCH resources may include: for the transmission on the PUCCH resources, the terminal device selects the first spatial relationship information based on the UCI carried in the transmission and one of the second spatial relationship information to be applied to the transmission on the PUCCH resource.

In an exemplary implementation, the UCI content carried in a transmission on one PUCCH resource may be any one or more of the following: Affirmative Scheduling Request (SR); PDSCH transmission or activated Semi-Persistent Scheduling (SPS) PDSCH HARQ-ACK information of received DCI format or DCI format indicating SPS PDSCH release; HARQ-ACK information of PDSCH without corresponding PDCCH using high layer parameter sps-Config; CSI report example.

In an exemplary implementation, for transmission on the first PUCCH resource, if the UCI carried in the transmission is SR or contains SR, the terminal device may be requested to apply the first spatial relationship information or the second spatial relationship information to Transmission in the first PUCCH resource.

In an exemplary implementation, if the first PUCCH resource is configured for SR transmission, the terminal device may be requested to apply the first spatial relationship information to the transmission in the first PUCCH resource. In other words, if the first PUCCH resource is configured by a higher layer parameter (such as SchedulingRequestResourceConfig) in the configured set of SR in PUCCH transmission using PUCCH format 0 or PUCCH format 1, the terminal device can be requested to set the first spatial relationship The information applies to transmissions in the first PUCCH resource. Optionally, in such a case, the terminal device may be requested to apply the second spatial relationship information to the transmission in the first PUCCH resource. There is no limit to this in the implementation of the present disclosure.

In an exemplary implementation, for transmission on the second PUCCH resource, if the UCI carried in the transmission contains HARQ- ACK information, the terminal device may be requested to apply the first spatial relationship information to the transmission in the second PUCCH resource; if the UCI carried in the transmission contains the DCI associated with the first high layer parameter set to the second value format scheduled PDSCH transmission HARQ-ACK information, the terminal device may be requested to apply the second spatial relationship information to the transmission in the second PUCCH resource.

For example, for a CORESET, a terminal device may be configured with an association between a CORESET and a first higher layer parameter. A CORESET configuration may be associated with a first higher layer parameter set to a first value. A CORESET configuration may be associated with a first higher layer parameter set to a second value. For example, the terminal device may be configured with CORESET, and in the configuration information of CORESET, the first high layer parameter may be set as the first value or the second value.

In an exemplary implementation, the network device can configure the association between the first high-layer parameter and the CORESET used to transmit the DCI format for scheduling PDSCH transmission, so that the terminal device can select the first spatial relationship information and the second spatial relationship information based on the association. One of the spatial relationship information is applied to the transmission of the HARQ-ACK information for the PDSCH transmission on the PUCCH resource.

For example, if the HARQ-ACK information is for a DCI format (e.g. DCI format 0_1 or 1_1 ) scheduled PDSCH, the terminal device may be requested to apply the first spatial relationship information to transmission in the second PUCCH resource. If the HARQ-ACK information is scheduled for a DCI format (eg DCI format 0_1 or 1_1) detected in the PDCCH in the search space associated with the CORESET (the CORESET is associated with the first higher layer parameter set to the second value) PDSCH, the terminal device may be requested to apply the second spatial relationship information to transmission in the second PUCCH resource.

In an exemplary implementation, the network device may configure the association between the first high layer parameter and the SPS configuration of the SPS PDSCH transmission, so that the terminal device can select one of the first spatial relationship information and the second spatial relationship information based on the association Transmission of HARQ-ACK information applied to SPS PDSCH transmission on PUCCH resources.

In one example, for HARQ-ACK information transmitted by SPS PDSCH, the SPS configuration may be associated with the value of the first higher layer parameter. The terminal device may be requested to use the associated value of the first higher layer parameter to determine which spatial relationship information is to be applied for the PUCCH transmission.

For example, a terminal device can be configured with SPS PDSCH transmission through the high layer parameter sps-config. In sps-config, the association with the first layer parameters can be configured. sps-config may be associated with a first higher layer parameter set to a first value. sps-config may be associated with a first higher layer parameter set to a second value.

For transmissions in PUCCH resources with UCI containing HARQ-ACK information for PDSCH transmissions without corresponding PDCCH transmissions using higher layer parameter sps-config, if sps-config with the first higher layer parameter set to the first value If associated, the terminal device may be requested to apply the first spatial relationship information.

For transmissions in PUCCH resources with UCI containing HARQ-ACK information for a PDSCH transmission without a corresponding PDCCH transmission using the higher layer parameter sps-config, if sps-config with the first higher layer parameter set to the second value If associated, the terminal device may be requested to apply the second spatial relationship information.

In an exemplary implementation, for HARQ-ACK information for SPS PDSCH transmissions, a terminal device may be requested to determine spatial relationship information for PUCCH transmissions from the PDCCH in which the DCI format activating the SPS transmission is detected. A PDCCH may be associated with a first higher layer parameter. If a PDCCH (in which a DCI format activating SPS transmission is detected) is associated with a first higher layer parameter set to a first value, the terminal device may be requested to apply the first spatial relationship information to the PUCCH transmission. If a PDCCH (in which a DCI format activating SPS transmission is detected) is associated with the first higher layer parameter set to a second value, the terminal device may be requested to apply the second spatial relationship information to the PUCCH transmission.

In an exemplary implementation, the network device can configure the association between the first high-layer parameter and the CORESET used to transmit the DCI format for activating SPSPDSCH transmission, so that the terminal device can select the first spatial relationship information and the second spatial relationship information based on the association. One of the spatial relationship information is applied to the transmission of the HARQ-ACK information of the SPS PDSCH transmission on the PUCCH resource.

For example, for a CORESET, a terminal device may be configured with an association between a CORESET and a first higher layer parameter. A CORESET configuration may be associated with a first higher layer parameter set to a first value. A CORESET configuration may be associated with a first higher layer parameter set to a second value.

For transmissions in PUCCH resources with UCI containing HARQ-ACK information for a PDSCH transmission without a corresponding PDCCH transmission, the PDSCH transmission is determined by the DCI format detected in the PDCCH in the search space associated with the CORESET (e.g. DCI format 0_1 or 1_1) is activated and the CORESET is associated with the first higher layer parameter set to the first value, the terminal device may be requested to apply the first spatial relationship information.

For transmissions in PUCCH resources with UCI containing HARQ-ACK information for a PDSCH transmission without a corresponding PDCCH transmission, the PDSCH transmission is determined by the DCI format detected in the PDCCH in the search space associated with the CORESET (e.g. DCI format 0_1 or 1_1) is active and the CORESET is associated with the first higher layer parameter set to the second value, the terminal device may be requested to apply the second spatial relationship information.

In an exemplary implementation, for the HARQ in the PUCCH resource of the DCI format that activates the SPS PDSCH transmission (such as DCI format 1_0 or DCI format 1_1) or the DCI format that indicates the release of SPS transmission (such as DCI format 1_0 or DCI format 1_1) - ACK information, the terminal device may be requested to determine the spatial relationship information for PUCCH transmission from the PDCCH (where the DCI format is detected). If a PDCCH (where a DCI format is detected) is associated with a first higher layer parameter set to a first value, the terminal device may be requested to apply the first spatial relationship information to the PUCCH transmission. If a PDCCH (where the DCI format is detected) is associated with the first higher layer parameter set to the second value, the terminal device may be requested to apply the second spatial relationship information to the PUCCH transmission.

In an exemplary implementation, the network device may configure the association between the first high-layer parameter and the CORESET used to transmit the DCI format for activating SPSPDSCH transmission or indicating the release of SPS PDSCH transmission, so that the terminal device can select the first layer based on the association. One of the first spatial relationship information and the second spatial relationship information is applied to the transmission of HARQ-ACK information in DCI format on the PUCCH resource.

For example, for a CORESET, a terminal device may be configured with an association between a CORESET and a first higher layer parameter. A CORESET configuration may be associated with a first higher layer parameter set to a first value. A CORESET configuration may be associated with a first higher layer parameter set to a second value.

PUCCH resource for UCI with HARQ-ACK information in DCI format (e.g. DCI format 1_0 or DCI format 1_1) that activates SPS PDSCH transmission or indicates release of SPS PDSCH transmission (e.g. DCI format 1_0 or DCI format 1_1) A terminal device may be requested to apply the first space if the DCI format is detected in the PDCCH in the search space associated with the CORESET (the CORESET is associated with the first higher layer parameter set to the first value) relationship information. The terminal device may be requested to apply the second spatial relationship information if a DCI format is detected in the PDCCH in the search space associated with the CORESET (the CORESET is associated with the first higher layer parameter set to the second value).

In an exemplary implementation, the network device may configure the association between the first high-layer parameter and the CSI report configuration of the CSI report, so that the terminal device can select one of the first spatial relationship information and the second spatial relationship information based on the association To be applied to the transmission of CSI on the PUCCH resource.

In an exemplary implementation, for CSI reporting on PUCCH resources, the terminal device may be requested to determine spatial relationship information for PUCCH transmission according to the CSI reporting settings configuring the CSI reporting. In the configuration of CSI reporting settings, a CSI reporting configuration may be associated with a first higher layer parameter. For CSI reporting on PUCCH resources, the terminal device shall apply spatial relationship information corresponding to the value of the first higher layer parameter associated with the CSI report configuration that configures the CSI report.

In an exemplary implementation, for CSI reporting on PUCCH resources, if the CSI reporting configuration is not associated with the first higher layer parameter, the terminal device may be requested to apply the corresponding first higher layer parameter set to the first value or the spatial relationship information corresponding to the first high-level parameter set to the second value.

In an exemplary implementation, for transmission on PUCCH resources, if UCI carries a PDSCH transmission scheduled by a DCI format not associated with the first higher layer parameter, or an SPS transmission not associated with the first higher layer parameter, or activates The DCI format of SPS PDSCH transmission but not associated with the first high layer parameter, or the HARQ-ACK information indicating the DCI format of SPS release but not associated with the first high layer parameter, the terminal device can be requested to apply the corresponding The spatial relationship information of the first higher layer parameter of a value or corresponds to the spatial relationship information of the first higher layer parameter set to a second value.

In an exemplary implementation, the spatial relationship information may be indicated by high-layer signaling, and the high-layer signaling may include the value of the first high-layer parameter and an indication of the corresponding spatial relationship information.

As an example, as shown in Figure 3, a MAC CE message indicating/activating spatial relation information (such as PUCCH-SpatialRelationInfo value) for PUCCH resources may be designed, wherein:

The field "serving cell ID" indicates the identity of the serving cell to which the MAC CE is applied.

The field "BWP ID" indicates the UL BWP to which the MAC CE is applied.

A field "P" represents a value of a first layer parameter to which the MAC CE is applied.

A field of bits S ₇ S ₆ S ₅ S ₄ S ₃ S ₂ S ₁ S ₀ indicates spatial relationship information for PUCCH resources.

In an exemplary implementation, PUCCH resources may be configured with a PUCCH group ID. A network device (eg gNB) may signal the spatial relationship information for the first PUCCH group ID, and then the terminal device may be requested to apply the indicated spatial relationship information to all PUCCH resources configured with the first PUCCH group ID.

In an exemplary implementation, in the configuration of the PUCCH resource, the terminal device may be configured with a high layer parameter PUCCH group ID. For example, the high layer parameter PUCCH group ID can take the value 0 or 1.

A network device (eg gNB) may use higher layer signaling such as a MAC CE message to signal spatial relation information (eg PUCCH-SpatialRelationInfo value), and a PUCCH group ID value. After receiving this message, the terminal device may be requested to apply the indicated spatial relationship information to all PUCCH resources configured with a PUCCH group ID having the indicated PUCCH group ID value.

In an exemplary implementation, in the configuration of the PUCCH of the BWP, the terminal device may be configured with one or more sets of PUCCH resource IDs. The gNB may use higher layer signaling such as one MAC CE message to signal the spatial relation information (eg PUCCH-SpatialRelationInfo value) and the group ID of a set of PUCCH resource IDs. After receiving the message, the terminal device may be requested to apply the indicated spatial relationship information to all PUCCH resources whose PUCCH resource IDs are included in the indicated PUCCH resource ID group.

In an exemplary implementation, a network device (such as a gNB) may signal spatial relationship information (such as a PUCCH-SpatialRelationInfo value) and a set of one or more PUCCH resource ID information to a terminal device, and the terminal device may be indicated by the request hypothesis The spatial relationship information for will be applied to all PUCCH resources as indicated in the signaled set of one or more PUCCH resource IDs. As an example, as shown in Figure 4, a MAC CE indicating/activating spatial relation information (such as PUCCH-SpatialRelationInfo value) for PUCCH resources may be designed, wherein:

The field "serving cell ID" indicates the identity of the serving cell to which the MAC CE is applied.

The field "BWP ID" indicates the UL BWP to which the MAC CE is applied.

A field of bits S ₇ S ₆ S ₅ S ₄ S ₃ S ₂ S ₁ S ₀ indicates spatial relationship information for PUCCH resources.

Field of bits P ₀ P ₁ ...P _(N-3)×8+7 : each of these bits corresponds to a UL specified by "Serving Cell ID" and "BWP ID" in the same MAC CE message An active PUCCH resource in the BWP. Bit P ₀ corresponds to the PUCCH resource with the lowest resource ID, bit P ₁ corresponds to the PUCCH resource with the second lowest resource ID, and so on. Each bit indicates whether the indicated spatial relationship information is to be applied to the corresponding PUCCH resource. If the _Pi field is set to 1, the indicated spatial relationship information will be applied to the corresponding PUCCH resource. If the _Pi field is set to 0, the indicated spatial relationship information will not be applied to the corresponding PUCCH resource.

其中M是在给定UL BWP中的活动的PUCCH资源的总数。The value of N can be:

where M is the total number of active PUCCH resources in a given UL BWP.

Those skilled in the art can understand that, in order to update the spatial relationship information, a process similar to that of the above exemplary implementation may be applied to indicate the updated value of the spatial relationship information to the terminal device.

An advantage of implementations of the present disclosure is flexibility. Network devices (eg gNBs) have complete flexibility to "group" the PUCCH resources for uplink beam indication according to the deployment scenario. Network equipment can dynamically change the grouping of PUCCH resources.

According to the implementation of the present disclosure, the terminal device can be configured with, for example, two pieces of spatial relationship information of PUCCH resources (such as two values of PUCCH-SpatialRelationInfo), and for one transmission on one PUCCH resource, the terminal device can be based on UCI content and The association of the PDCCH transmission carried in this transmission dynamically determines which spatial relationship information should be applied. The proposed method can avoid statically dividing PUCCH resources into two groups, which will lead to waste of PUCCH resources.

According to the implementation of the present disclosure, in a multi-TRP system, PUCCH resources can be shared by all TRPs. Therefore, the configuration of PUCCH resources has greater flexibility and is more efficient.
