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 apparatus for indicating special relationship information.

Background

In New Radio (NR)3GPP specification release 15, beam indication is performed 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 PUCCH resource sets, and in each PUCCH resource set, the terminal device is configured with one or more PUCCH resources. For transmission on each PUCCH resource, the terminal device is configured with spatial relationship information, e.g. the parameter PUCCH-spatial relationship info, which may contain one or more reference signal resource IDs. Each of these reference signal resources is used to provide information about which transmission beam the terminal device uses 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 the 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 an uplink transmission beam corresponding to a reception beam used to receive CSI-RS resource transmissions or SS/PBCH block transmissions on the PUCCH resource. The base station (e.g., the gNB) may configure only one PUCCH-spatial relationship info value to the PUCCH resource, and the gNB may reconfigure the parameter when the gNB wants to switch a transmission beam of the PUCCH resource. The base station may also configure a plurality of PUCCH-spatial relationship info values to a PUCCH resource in Radio Resource Control (RRC), and then activate one of those configured PUCCH-spatial relationship info values as a current transmission beam of the PUCCH resource using Medium Access Control (MAC) Control Element (CE) signaling. If the base station wants to switch a transmission beam of one PUCCH resource, the base station may indicate another PUCCH-spatial relationship info value of the PUCCH resource using the MAC CE message. The base station may indicate a PUCCH-spatial relationinfo value of each PUCCH resource using the MAC CE message. The advantage of this approach 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 for all these PUCCH resources, 128 MAC CE messages need to be transmitted, since the above method only allows beam indication per PUCCH resource. Therefore, a new method for beam indication of PUCCH resources is needed for the purpose of lower signaling overhead.

A terminal device in implementations of the present disclosure may refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. An access terminal may be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, a terminal device in a 5G network or a terminal device in an evolved Public Land Mobile Network (PLMN), and so forth, without limitation in implementations of the present disclosure.

A network device (e.g., a base station) in implementations of the present disclosure may be a device for communicating with a terminal device, and the network device may be a Base Transceiver Station (BTS) in a GSM or CDMA system, a node b (nb) in a WCDMA system, an evolved base station (eNB or eNodeB) in an LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device (e.g., a gNB) in a 5G network, or a network device in an evolved PLMN, etc., which are not limited in implementations of the present disclosure.

FIG. 1 illustrates a schematic diagram of an exemplary application scenario in which implementations of the present disclosure may 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 a communication service 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 terminal device 10 and 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 the high frequency band. In high frequency band systems, such as millimeter wave systems, base stations and terminal devices may be deployed with a large number of antennas, so that large gain beamforming may be used to overcome large path loss and signal blocking. Due to hardware limitations and costs, base stations and terminal devices may only be equipped with a limited number of transmit and receive units (TXRUs). Thus, the hybrid beamforming mechanism may be utilized in both the base station and the terminal device. 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 particular downlink or uplink transmission. For downlink transmissions they need to find the best base station transmit beam and terminal device receive beam pair, and for uplink transmissions they need to find the best terminal device transmit beam and base station receive beam pair.

For communication between the terminal device and the base station, the base station and the terminal device need to determine which transmit and receive beams are to be used. As the 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 may measure one or more transmission beams of the base station, and then the terminal device may select the best transmission beam and report its selection to the base station. By measuring the transmit beams of the base station, the terminal device may 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 may also measure one or more transmit beams of the terminal device and then select the best transmit beam of the terminal device for uplink transmission. To support measuring the transmit beams of the base station, the base station may transmit multiple Reference Signal (RS) resources and then configure the terminal device to measure those RS resources. The terminal device may then report an index of one or more selected RS resources selected based on some measurement metric, such as layer 1 reference signal received power (L1-RSRP). To support measuring the transmit beams of the terminal device for uplink transmissions, the base station may configure the terminal device to transmit one or more uplink RS resources (e.g., Sounding Reference Signal (SRS) resources), which the base station may then measure. The base station may determine which transmit beam of the terminal device is best for uplink transmission based on measuring, for example, L1-RSRP of those RS resources.

In the beam indication function, for downlink transmission, the base station may indicate to the terminal device which transmit beam of the base station is used for transmission so that the terminal device may receive the downlink transmission using the appropriate receive beam. For Physical Downlink Control Channel (PDCCH) transmissions, the base station may indicate to the terminal device the Identity (ID) of one of the base station's transmit beams. For Physical Downlink Shared Channel (PDSCH) transmission, the base station may indicate an ID of one transmission beam for transmitting a corresponding PDSCH using a downlink control channel (DCI) in the PDCCH. For uplink transmissions from the 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 a transmission beam indicated by the base station through configuration of spatial relationship information (e.g., PUCCH-spatial relationship info). For Sounding Reference Signal (SRS) transmission, the terminal device should use a transmission beam indicated by the base station through configuration of spatial relationship information. For Physical Uplink Shared Channel (PUSCH) transmission, the terminal device should use the transmission beam indicated by the information element contained in the scheduling DCI.

The function of beam switching is used by the base station to switch transmission beams for downlink or uplink transmission. This function is useful when the transmission beam used for 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 that is better than the current transmission beam, the base station may send signaling to the terminal device to inform of the change of the transmission beam. Similarly, the base station may switch the uplink transmission beam of the terminal device for transmitting some uplink transmissions.

In a communication system, such as a New Radio (NR) system, Downlink (DL) signals may include control signaling that conveys DL Control Information (DCI) over a PDCCH channel, data signals that convey information packets over a PDSCH channel, and some types of reference signals. The DCI may indicate information on how the PDSCH is transmitted, including, for example, resource allocation and transmission parameters of the PDSCH. The base station may transmit one or more types of reference signals for different purposes, including demodulation reference signals (DM-RS) transmitted with the PDSCH and usable by the terminal device to demodulate the PDSCH, channel state information reference signals (CSI-RS) usable by the terminal device to measure CSI of a transmission beam of the base station or a downlink channel between the base station and the terminal device, and phase tracking reference signals (PT-RS) also transmitted with the PDSCH and usable by the terminal device to estimate phase noise caused by imperfections in Radio Frequency (RF) parts in the transmitter and receiver, and then compensate for the phase noise when decoding the PDSCH. In NR, DL resource allocation to PDCCH, PDSCH and reference signals is performed in units of Orthogonal Frequency Division Multiplexing (OFDM) symbols and in units of Physical Resource Block (PRB) groups. Each PRB contains some, e.g. 12, Resource Elements (REs) in the frequency domain. The transmission Bandwidth (BW) for one downlink transmission consists of frequency resource elements called Resource Blocks (RBs), and each RB consists of some, e.g., 12, subcarriers or REs.

Uplink (UL) signals transmitted by the terminal device to the base station may include data signals conveying data packets over a PUSCH channel, uplink control signals conveying UL Control Information (UCI) that may be transmitted in a PUSCH or PUCCH channel, and UL reference signals. The UCI may carry Scheduling Requests (SRs) used by the terminal device to request uplink transmission resources, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for PDSCH transmissions, or CSI reports. The terminal device may transmit one or more types of uplink reference signals for different purposes, including DM-RS transmitted with PUSCH transmission and usable by the base station to demodulate PUSCH, PT-RS also transmitted with PUSCH and usable by the base station to estimate phase noise caused by imperfections in the RF section and which the base station may then mute the phase noise when decoding PUSCH, and SRS signals used by the base station to measure CSI for one or more terminal device transmission beams or uplink channels between the terminal device 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 interval of a DL or UL channel/signal is called a slot, each slot containing some, e.g. 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 msec for subcarrier spacing of 15KHz, 30KHz, 60KHz, and 120KHz, respectively. NR systems support a flexible set of basic parameters 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 base parameters.

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

For multiple transmit/receive point (multi-TRP) transmissions, a terminal device may apply different transmission beams on PUCCH resources targeted for different TRPs. The design in release 15 can support this. However, an unnecessarily large amount of signaling overhead remains a problem here, since all PUCCHs targeted to the same TRP typically use the same transmission beam, and the number of TRPs in a multi-TRP transmission is typically not large, e.g. 2.

In the present disclosure, methods and devices for indicating spatial relationship information for beam indication of PUCCH channels are presented. In the present 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, a method for indicating spatial relationship information according to an exemplary implementation of the present disclosure may include acts 210 and 220.

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

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

In one exemplary implementation, the spatial relationship information may include at least first and second spatial relationship information, and the network device may configure the first higher layer parameter. The value of the first higher layer parameter may include at least a first value and a second value, the first spatial relationship information may correspond to the first higher layer parameter being the first value, and the second spatial relationship information may correspond to the first higher layer parameter being the second value.

In one exemplary implementation, it is assumed that there are two TRPs in a multiple TRP transmission scenario. The skilled person will appreciate that there may be an additional number of TRPs in a multiple TRP transmission scenario, these two TRPs being considered herein as examples only. The terminal device may be configured with a first higher layer parameter, e.g. called PDCCH group ID, which may take two possible values: the first and second values, and the first higher layer parameter may be configured to a control resource set (CORESET) configured to the terminal device. The first higher layer parameter may be used to identify a TRP in a multiple TRP transmission. Examples of values for the 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, which is not limited in implementations of the present disclosure. In another example of identifying a TRP by a first higher layer parameter, in the configuration of CORESET, the first higher layer parameter may be "present" or "absent", wherein CORESET having a configuration in which the first higher layer parameter is "present" may be used by one TRP, and CORESET having a configuration in which the first higher layer parameter is "absent" may be used by another TRP. The particular manner in which a TRP is identified by a first higher layer parameter is not limited in implementations of the present disclosure, and for ease of description and by way of example, different values (e.g., two values) of the first higher layer parameter are used to identify a TRP in a multiple TRP transmission in the exemplary implementations below.

First spatial relationship information (e.g., a first PUCCH-SpatialRelationInfo value) in which the first higher layer parameter is a first value and second spatial relationship information (e.g., a second PUCCH-SpatialRelationInfo value) in which the first higher layer parameter is a second value may be indicated to the terminal device. Then, for transmission on a PUCCH resource, the terminal device may be requested to select one from the first spatial relationship information and the second spatial relationship information to apply to transmission on the PUCCH resource based on UCI report content carried in the transmission.

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

In one exemplary implementation, the UCI content carried in the transmission on one PUCCH resource may be any one or more of the following: a positive Scheduling Request (SR); HARQ-ACK information of a DCI format transmitted by a PDSCH or activated for semi-persistent scheduling (SPS) PDSCH reception or indicating a DCI format for SPS PDSCH release; HARQ-ACK information of the PDSCH without the corresponding PDCCH using the high-layer parameter sps-Config; CSI reporting examples.

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

In one 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 transmission in the first PUCCH resource. In other words, if the first PUCCH resource is configured by a higher layer parameter (e.g., scheduling request resource config) in the configured set of SRs in PUCCH transmission using PUCCH format 0 or PUCCH format 1, the terminal device may be requested to apply the first spatial relationship information to transmission in the first PUCCH resource. Alternatively, 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 limitation to this in the implementation of the present disclosure.

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

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

In one exemplary implementation, the network device may configure an association between the first higher layer parameter and a CORESET used to transmit a DCI format scheduling a PDSCH transmission to enable the terminal device to select one of the first spatial relationship information and the second spatial relationship information to apply to transmission of HARQ-ACK information for a PDSCH transmission on a PUCCH resource based on the association.

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

In one example implementation, the network device may configure an association between the first higher layer parameter and an SPS configuration of SPS PDSCH transmissions to enable the terminal device to select one of the first spatial relationship information and the second spatial relationship information to apply to transmission of HARQ-ACK information for SPS PDSCH transmissions on PUCCH resources based on the association.

In one example, the SPS configuration may be associated with a value of a first higher layer parameter for HARQ-ACK information for SPS PDSCH transmission. 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 to the PUCCH transmission.

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

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

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

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

In one exemplary implementation, the network device may configure an association between the first higher layer parameter and a CORESET used to transmit a DCI format activating an SPS PDSCH transmission to enable the terminal device to select one of the first spatial relationship information and the second spatial relationship information to apply to transmission of HARQ-ACK information for the SPS PDSCH transmission on the PUCCH resource based on the association.

For example, for CORESET, the end device may be configured with an association between CORESET and the first higher layer parameters. The CORESET configuration may be associated with a first higher layer parameter set to a first value. The 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 PDSCH transmissions without a corresponding PDCCH transmission, the PDSCH transmission being activated by a DCI format (e.g., DCI format 0_1 or 1_1) detected in the PDCCH in the search space associated with CORESET and the CORESET being 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.

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

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

In one exemplary implementation, the network device may configure an association between the first higher layer parameter and a CORESET used to transmit a DCI format that activates or indicates release of SPS PDSCH transmission to enable the terminal device to select one of the first spatial relationship information and the second spatial relationship information to apply to transmission of HARQ-ACK information for the DCI format on the PUCCH resource based on the association.

For transmission in PUCCH resources with HARQ-ACK information containing a DCI format (e.g., DCI format 1_0 or DCI format 1_1) activating an SPS PDSCH transmission or a DCI format indicating a release of an SPS PDSCH transmission (e.g., DCI format 1_0 or DCI format 1_1), the terminal device may be requested to apply the first spatial relationship information if the DCI format is detected in a PDCCH in a search space associated with a CORESET (CORESET is associated with a first higher layer parameter set to a first value). The terminal device may be requested to apply the second spatial relationship information if the DCI format is detected in the PDCCH in the search space associated with CORESET (CORESET is associated with the first higher layer parameter set to the second value).

In one exemplary implementation, the network device may configure an association between the first higher layer parameter and a CSI reporting configuration of the CSI report to enable the terminal device to select one of the first spatial relationship information and the second spatial relationship information to apply to transmission of the CSI on the PUCCH resource based on the association.

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

In one 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 spatial relationship information corresponding to the first higher layer parameter set to a first value or spatial relationship information corresponding to the first higher layer parameter set to a second value.

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

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

As an example, a MAC CE message indicating/activating spatial relationship information (e.g., PUCCH-SpatialRelationInfo value) for PUCCH resources may be designed as shown in fig. 3, where:

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

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

The field "P" indicates a value of a first higher layer parameter of the application MAC CE.

Bit S₇ S₆ S₅ S₄ S₃ S₂ S₁ S₀Indicates spatial relationship information for PUCCH resources.

In one exemplary implementation, PUCCH resources may be configured with a PUCCH group ID. The network device (e.g., the gNB) may signal 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 one exemplary implementation, in the configuration of PUCCH resources, a terminal device may be configured with a higher layer parameter PUCCH group ID. For example, the higher layer parameter PUCCH group ID may take the

value

0 or 1.

The network device (e.g., the gNB) may use higher layer signaling such as a MAC CE message to signal spatial relationship information (e.g., PUCCH-SpatialRelationInfo value), and a PUCCH group ID value. Upon receiving the 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 one exemplary implementation, in the configuration of PUCCH for BWP, the terminal device may be configured with one or more sets of PUCCH resource IDs. The gNB may use higher layer signaling, e.g., a MAC CE message, to signal spatial relationship information (e.g., PUCCH-SpatialRelationInfo value) and a group ID for a group of PUCCH resource IDs. Upon 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 one exemplary implementation, a network device (e.g., a gNB) may signal spatial relationship information (e.g., PUCCH-spatial relationinfo values) and a set of one or more PUCCH resource ID information to a terminal device, which may be requested to assume that the indicated spatial relationship information is to be applied to all PUCCH resources as indicated in the signaled set of one or more PUCCH resource IDs. As an example, a MAC CE indicating/activating spatial relationship information (e.g., PUCCH-SpatialRelationInfo value) for PUCCH resources may be designed as shown in fig. 4, where:

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

Bit P₀P₁…P_(N-3)×8+7The field of (c): each of these bits corresponds to a one specified by "serving cell ID" and "BWP ID" in the same MAC CE messageOne active PUCCH resource in UL BWP. Bit P₀Corresponding to PUCCH resource with lowest resource ID, bit P₁Corresponding 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 a corresponding PUCCH resource. If P is_iThe field is set to 1, and the indicated spatial relationship information will be applied to the corresponding PUCCH resource. If P is_iThe field is set to 0, the indicated spatial relationship information will not be applied to the corresponding PUCCH resource.

The value of N may be:

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

The skilled person will appreciate that for updating the spatial relationship information, a similar procedure to that of the above exemplary implementation may be applied for indicating the updated value of the spatial relationship information to the terminal device.

An advantage of the implementation of the present disclosure is flexibility. The network device (e.g., the gNB) has full flexibility to "group" PUCCH resources for uplink beam indication according to the deployment scenario. The network device can dynamically change the grouping of PUCCH resources.

According to implementations of the present disclosure, a terminal device may be configured with, for example, two pieces of spatial relationship information (e.g., two values of PUCCH-spatial relationship info) for a PUCCH resource, and for one transmission on one PUCCH resource, the terminal device may dynamically determine which spatial relationship information should be applied based on UCI content and an association with a PDCCH transmission carried in the transmission. The proposed method may avoid statically dividing PUCCH resources into two groups, which would result in a waste of PUCCH resources.

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