Description

[Technical field]

[0001] FIELD Exemplary embodiments of the present disclosure relate generally to the field of communications technologies, and more particularly to methods, apparatus, and media for handling panel-related information. [Background technology]

[0002] In order to meet the increasing demand for wireless data traffic, several schemes have been proposed and implemented, with Multiple Input Multiple Output (MIMO) technology being considered as a powerful scheme to achieve high data throughput in communication systems. MIMO includes a feature that facilitates the use of multiple antenna elements in a network device (e.g., base station, BS) for both sub-6 GHz and above-6 GHz frequency bands.

[0003] It is further proposed that a terminal device (e.g., user equipment) may be deployed with multiple antenna elements (sometimes referred to as panels). In the 3rd-generation partnership project (3GPP) Release 17 (Rel-17), it is agreed that a terminal device and a network device may exchange panel-related information. Specifically, a list of capability parameter sets (sometimes referred to as "UE#" or "capability value set") may be reported to the network device. It is also proposed to send a correspondence report (e.g., beam report) to the network device indicating a correspondence between each reported reference signal (RS) index and one of the capability parameter sets in the reported list, so that the terminal device can perform a user equipment (UE)-initiated panel activation and selection procedure. However, details for handling panel-related information (e.g., configuration, reporting, and feedback) still need to be further described.

For example, a circuit may be a combination of analog and / or digital hardware circuitry and software / firmware. As yet another example, a circuit may be any portion of a hardware processor having software, including a digital signal processor, software, and one or more memories, that cooperate to cause a device, such as a terminal device or a network device, to perform various functions.

As used herein, the term "circuitry" also includes an implementation of only a hardware circuit or one or more processors, or a portion of a hardware circuit or one or more processors and its (or their) associated software and / or firmware.

[0042] As mentioned above, it is proposed that a terminal device may be deployed with multiple antenna elements (sometimes referred to as panels). It is further agreed that the terminal device may inform the network device of panel-related information. However, details for handling panel-related information (e.g., configuration, reporting, and feedback) need to be further explained.

[0043] Please refer to Fig. 1, which shows an interaction timing 100 between a network device and a terminal device in a related solution. In the specific example of Fig. 1, the terminal device is deployed with two panels, panel #1 and panel #2 (indexed as panel #1 and panel #2), which correspond to UE capability value sets #1 and #2, respectively. Furthermore, the UE capability value set #1 is associated with beams #1 and #2 and supports a 2-port sounding reference signal (SRS), and the UE capability value set #2 is associated with beams #3 and #4 and supports a 4-port SRS.

[0044] In operation, the terminal device determines which beams can be used for uplink transmission for different panels, for example by measuring downlink RS, and the terminal device may expose some of its panel capabilities and structures to the network device. As shown in Figure 1, at time T1, the terminal device may report a list of UE capability value sets (110), for example via RRC signaling. However, it is still open as to which parameters should be included in the UE capability value set.

[0045] It has also been agreed that a correspondence report indicating the correspondence between each reported RS index and one of the UE capability value sets is sent to the network device. As shown in FIG. 1, at time T2, the terminal device sends a correspondence report associated with panel #2 (i.e., UE capability value set #2) to the network device (120), and sends another correspondence report associated with panel #1 (i.e., UE capability value set #1) (130). However, the format of the correspondence report and how to set the reporting of the correspondence report are still pending.

[0046] Furthermore, due to the complex communication environment, it is not guaranteed that the transmission of the correspondence report is always successful. As shown in FIG. 1, the transmission of the other correspondence report fails. In this case, after transmitting the other correspondence report, the terminal device may consider applying the UE capability value set #1, but the network device still applies the UE capability value set #2. Therefore, the failure to transmit the other correspondence report causes a misalignment in uplink transmission capability between the network device and the terminal device. In the specific example of FIG. 1, after time T3, the network device may request the terminal device to transmit SRS / Physical Uplink Shared Channel (PUSCH) on four antenna ports, which cannot be supported by the terminal device. In addition, the network device may schedule the terminal device to transmit on beams #3 and #4, but the terminal device only supports transmitting on beams #1 and #2. In short, the misalignment between the network device and the terminal device makes it impossible to continue the communication between the network device and the terminal device normally.

[0047] Therefore, a feedback mechanism for correspondence reporting appears to be needed. This can be solved by introducing a new message / signaling, including a new Radio Network Temporary Identifier (RNTI) or a new Downlink Control Information (DCI) format or field, for feedback on correspondence reporting. However, the introduction of a new message / signaling may cause undesirable additional overhead and complexity. In this case, it is necessary to further explain how to realize the feedback mechanism for correspondence reporting.

[0048] In addition, the correspondence report may cause switching / changing between different panels / UE capability sets / RSs / beams. Such switching / changing needs to be coordinated in both the network device and the terminal device. Therefore, the switching operation in the network device and the terminal device during the feedback procedure should also be specified in detail.

[0049] As can be seen with reference to Figure 1, during the period between time T1 and time T2, there is no correspondence report transmitted to the network device, so both the network device and the terminal device do not know which panel / UE capability value set / RS / beam should be applied. Therefore, it is also desirable to propose a solution on how to perform the initial transmission between the network device and the terminal device.

[0050] Additionally, fallback procedures are usually required during communication procedures. Currently, the fallback procedures after sending the correspondence report are still open.

[0051] In addition to the above, there are still other open issues, including but not limited to whether the UE capability value set can be common across all bandwidth parts (BWPs) / component carriers (CCs) within the same band or band combination, or whether / how to perform downlink-only panel-related information reporting, how to configure the time domain behavior of correspondence reporting, etc.

[0052] Some of the embodiments solve at least some of the outstanding problems set forth above. It should be understood that the above exemplified problems are provided for illustrative purposes only and no limitations are implied. None of these outstanding problems and the problems solved by the present disclosure are limited to the above exemplified problems.

[0053] Generally speaking, a panel as described herein refers to one or more antenna elements deployed in an area of ​​a terminal device, and in this regard, the terms "panel," "antenna element," "antenna array," "transmit / receive point," "TRP" (and their equivalents) may be used interchangeably.

[0054] In some embodiments, the terminal device may be configured to have a list of transmission configuration indicator (TCI) state (e.g., up to M TCI states) configurations with tci-StateId. Each TCI state includes quasi-co-located (QCL) RSs for demodulation reference signals (DM-RSs) of physical downlink shared channels (PDSCHs) and DM-RSs of physical downlink control channels (PDCCHs) in a component carrier (CC), references for providing CSI-RSs and (if applicable) for determining unlink TX spatial filters for dynamic and configured grant-based physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resources, and parameters for providing SRSs. The quasi-co-located relationship is configured by higher layer parameters qcl-Type1 of the first RS and qcl-Type2 of the second RS (if configured). The quasi-co-located type corresponding to each DL RS is given by higher layer parameter qcl-Type in QCL-Info and can be one of the following values: - "typeA": {Doppler shift, Doppler spread, average delay, delay spread} - "type B": {Doppler shift, Doppler spread} - "type C": {Doppler shift, average delay} - "typeD": {spatial reception parameters}

[0055] The terms "TCI", "TCI state", "TCI identity", "TCI ID", and "TCI state ID" may be used interchangeably.

[0056] The terms "set of capability parameters", "capability value set", and "UE capability value set" may be used interchangeably.

[0057] Additionally, in this specification, the terms "CC identity / index", "cell identity / index", and "serving cell identity / index" (and their equivalents) may be used interchangeably.

[0058] In some embodiments, the terms “RS,” “beam,” “set of QCL parameters,” “TCI state,” “QCL ​​type,” “QCL ​​type D,” “spatial receive parameters,” “spatial domain parameters,” “spatial domain filter,” “spatial domain transmit filter,” “spatial domain receive filter,” “spatial receive parameters,” and “spatial relationship information” have similar meanings and may be used interchangeably.

[0059] In some embodiments, a panel / capability set may refer to a downlink panel / capability set, an uplink panel / capability set, a panel / capability set with reserved / specific state, a panel / capability set type, a panel / capability set state, an RS resource, an RS resource set, an antenna port, an antenna port group, a beam, or a beam group.

[0060] In some embodiments, the panel identity information may refer to a panel index / identity, a downlink panel index / identity, an uplink panel index / identity, a panel type indication, a panel state indication, a capability value set index, an RS resource set index / identity, an antenna port index / identity, an antenna port group index / identity, or a beam group index / identity. Example environment

[0061] FIG. 2 illustrates an example communications environment 200 in which example embodiments of the present disclosure may be practiced.

[0062] The communication environment 200 includes a network device 210 and a terminal device 220, which can communicate with the terminal device 220 via a physical communication channel or link. Additionally, the network device 210 may provide more than one serving area. In the example of FIG. 2, the network device 210 provides a (serving) cell 260.

[0063] In the specific example of the communication environment 200, a link from the terminal device 220 to the network device 210 is referred to as an uplink, and a link from the network device 210 to the terminal device 220 is referred to as a downlink. Furthermore, the communication environment supports MIMO such that the network device 210 and the terminal device 220 communicate via different beams to enable directional communication. In the downlink, the network device 210 is a transmitting (TX) device (or transmitter) and the terminal device 220 is a receiving (RX) device (or receiver), and the network device 210 may transmit downlink transmissions to the terminal device 220 via one or more beams. As shown in FIG. 2, the network device 210 transmits downlink transmissions to the terminal device 210 via beams 240-1 to 240-3.

[0064] Accordingly, in the uplink, network device 210 is an RX device (or receiver), terminal device 220 is a TX device (or transmitter), and terminal device 210 may transmit uplink transmissions to network device 220 via one or more beams. As shown in FIG. 2, terminal device 220 transmits uplink transmissions to network device 210 via beams 230-1 to 230-3. For purposes of explanation, beams 230-1 to 230-3 or beams 240-1 to 240-3 will be referred to collectively or individually as beams 230 or beams 240, respectively.

[0065] Additionally, the terminal device 220 may be deployed with more than one panel. As shown in FIG. 2, the terminal device 220 is deployed with panels 250-1 and 250-2. Hereinafter, the panels 150-1 and 250-2 may be referred to as a first panel 250-1 and a second panel 250-2, respectively. In some embodiments, the panels 250-1 and 250-2 may each correspond to a different set of capability parameters.

[0066] In some embodiments, a panel may be associated with one or more RS / beams, and thus, terminal device 220 may use a particular panel to transmit a directional signal to network device 210 via a particular beam associated with an RS.

[0067] In some embodiments, different panels correspond to different panel types / capability sets. For example, panels 250-1 and 250-2 may correspond to different numbers of SRS ports, frequency resources (frequency bands, CCs, beams, etc.), and any other suitable capability parameters (e.g., capability sets).

[0068] In addition, in the embodiment of Fig. 2, the exchange of panel-related information is supported. Specifically, in the embodiment of Fig. 2, the network device 210 and the terminal device 220 may exchange capability-related information and related settings, and the terminal device 220 may report a correspondence relationship report to the network device 210.

[0069] In some embodiments, terminal device 220 may perform UE-initiated panel activation and selection via reporting a list of UE capability sets.

[0070] In some embodiments, one or more RSs (e.g., Synchronization Signal / Physical Broadcast Channel (SS / PBCH) blocks, SSBs, Sounding Reference Signals, SRSs, CSI-RSs, etc.) may be associated with a beam. The terminal device 220 may measure on the beams / RSs and transmit the measurement results to the network device 210, for example, via a correspondence report.

[0071] In addition, the correspondence between each reported CSI-RS and / or SSB resource index and one capability parameter in the capability parameter set in the reported list is determined by the terminal device 220 / set by the network device 210 and notified to the network device 210 in the beam reporting instance.

[0072] In some embodiments, the index of the corresponding capability parameter is reported together with the SSB Resource Indicator (RI) / CSI-RS Resource Indicator (CRI) and L1-RSRP / SINR pairs (up to four pairs, with 7-bit absolute value and 4-bit differential value) in the uplink control information for beam reporting.

[0073] Additionally, the terminal device 220 may report one index for all CRI / SSB RIs reported in one beam report. Alternatively, the terminal device 220 may report one index for each CRI / SSB RI reported in one beam report.

[0074] In some embodiments, DL-only reporting is supported, which is described in the following text.

[0075] In some embodiments, the network device 210 provides configurations for correspondence reporting (e.g., time domain behavior of correspondence reporting, format of correspondence reporting) and resources (e.g., Physical Uplink Control Channel (PUCCH) / Physical Uplink Shared Channel (PUSCH) resources, beams, RS, etc.), which also indicate when, how, and where to report the correspondence report.

[0076] In some embodiments, correspondence reporting may be configured to have any suitable time domain behavior. One example of a time domain behavior is periodic. Another example of a time domain behavior is semi-persistent. Yet another example of a time domain behavior is aperiodic.

[0077] Communications in the communication environment 200 may conform to any suitable standard, including, but not limited to, Long Term Evolution (LTE), LTE-Evolution, LTE-Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), and the like. Furthermore, communications may be performed according to any currently known or future developed generation of communications protocols. Examples of communications protocols include, but are not limited to, first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G), 5.5G, 5G-Advanced networks, or sixth generation (6G) communications protocols.

[0078] It should be understood that the number of network devices, terminal devices, panels, and cells and their interrelationships are used for illustrative purposes only and do not imply any limitations. Communications environment 200 may include any suitable network devices, terminal devices, panels, and cells suitable for implementing embodiments of the present disclosure. Additionally, it should be understood that one or more additional terminal devices may be located within each cell.

[0079] It should also be appreciated that in some instances, communication environment 200 may include only homogeneous network deployments or only heterogeneous network deployments. Process Example

It should be appreciated that the interactions may be realized in one signaling / message or multiple signaling / messages, including system information, RRC messages, DCI messages, uplink control information (UCI) messages, media access control (MAC) control elements (CE), etc. The present disclosure is not limited in this respect.

In the following, some operations are described from the perspective of the terminal device 220, but it should be understood that the corresponding operations should be performed by the network device 210. Similarly, some operations are described from the perspective of the network device 210, but it should be understood that the corresponding operations should be performed by the terminal device 220.

[0085] Additionally, terminal device 220 may be configured with more than one panel (e.g., panel 250-1 and panel 250-2) and support more than one capability set. Both panels and capability sets may be indexed according to ascending or descending order. Exemplary Process for Exchanging Capability-Related Information

[0086] Optionally, the terminal device 220 and the network device 210 may communicate capability-related information and related settings to enable related functions according to the present disclosure described below. During this interactive procedure, certain rules for setting and reporting correspondence reports may be defined, and related redefined / newly introduced parameters may be exchanged between the terminal device 220 and the network device 210. Additionally, the network device 210 may enable or disable related functions according to the present disclosure.

[0087] 3, terminal device 220 transmits capability-related information to network device 210 (310). According to some embodiments of the present disclosure, more fields indicating the panel capabilities of terminal device 220 are included in the capability-related information (e.g., via one or more capability reports). In this way, better alignment of panel capabilities and panel structures between network device 210 and terminal device 220 can be achieved.

[0088] Additionally, the capability related information and related settings may be carried in any suitable signaling / messages, including but not limited to RRC messages, DCI messages, MAC CE, etc. Thus, existing signaling structures may be reused and updated to accommodate reporting of CSI reports associated to capability parameter sets.

[0089] In some embodiments, the capability-related information may indicate capability-related information indicating multiple capability value sets (e.g., L capability value sets, where the value of L may be a positive integer) supported by the terminal device 220.

[0090] In some embodiments, one capability value set may be associated with one or more RSs (e.g., SSB resource indicator, SSBRI, CSI-RS resource indicator, CRI), and one RS may also be associated with one or more capability value sets. In other words, the correspondence between capability value sets and RSs may be one-to-one, one-to-many, many-to-one, or many-to-many.

[0091] Furthermore, the capability value set may include multiple capability parameters. One capability parameter included in the set is the maximum number of SRS ports (represented as “Nx”). The maximum number of SRS ports Nx refers to Nx radio frequency (RF) chains for uplink transmission and Nx layers for PUSCH.

[0092] Alternatively or additionally, other ability parameters included in the set are: - identity information for the ability set; ● Maximum number of SRS ports, ● Maximum number of SRS resources, ● Maximum number of SRS resource sets; ● Coherence type (e.g., fully coherent, partially coherent, non-coherent, and combinations thereof); ● Maximum number of uplink layers; ● Maximum number of downlink layers; ● Maximum number of RS (e.g. CSI-RS) ports, - the maximum number of codewords, or ● Maximum number of MIMO layers; The parameter may be any suitable parameter, including but not limited to:

[0093] By reporting more capability parameters within each capability value set to the network device 210 , the network device 210 can better understand the capabilities of the terminal device 220 and facilitate more appropriate scheduling for the terminal device 220 .

[0094] Furthermore, in addition to a list of capability value sets, more capability-related information may be communicated to the network device 210, as described below.

[0095] In some embodiments, one capability value set corresponds to a panel (physical or logical entity) installed in the terminal device 220. In other words, each capability value set corresponds to one panel. In this case, the values ​​of capability parameters included in different capability value sets may be the same.

[0096] Alternatively or additionally, in some embodiments, one capability value set may correspond to a particular panel type, where the capability parameters included in different capability value sets have different (or at least partially different) values. In one exemplary embodiment, the type of panel may be defined by the number of SRS ports supported, e.g., Type #1 corresponds to 1-port SRS, Type #2 corresponds to 2-port SRS, Type #3 corresponds to 4-port SRS, etc.

[0097] Also, in some embodiments, the capability-related information indicates whether a symmetric antenna structure (i.e., a symmetric panel) or an asymmetric antenna structure (i.e., an asymmetric panel) is deployed in the terminal device. Alternatively or additionally, in some embodiments, the capability-related information indicates a respective number of capability value sets corresponding to each particular type of capability value set.

[0098] In one particular exemplary embodiment, the capability-related information indicates a capability value set #1 (including a capability value of 2-port SRS) each having a number of 2, which means that the terminal device 220 is equipped with two panels and both panels can support 2-port SRS. In another particular exemplary embodiment, when the terminal device 220 is equipped with two panels, the capability-related information indicates a capability value set #2 (including a capability value of 4-port SRS) and a symmetric antenna structure, which means that the terminal device 220 is equipped with two panels and both panels can support 4-port SRS. For the sake of brevity, other exemplary embodiments will not be described one by one.

[0099] Alternatively or additionally, in some embodiments, one set of capability scores may correspond to a particular panel state. In one exemplary embodiment, a panel state may be defined by the number of panels activated, e.g., state #1 corresponds to single panel transmission, state #2 corresponds to two simultaneous panels transmission, state #3 corresponds to four simultaneous panels transmission, etc. This exemplary embodiment is particularly suited to scenarios where multiple simultaneous panel transmission is supported.

[0100] In one exemplary embodiment, the capability-related information further indicates an association relationship between the plurality of capability value sets. In some embodiments, the capability-related information indicates whether one capability value of the reported capability value set is a subset of another reported capability value set.

[0101] In one particular exemplary embodiment, the capability-related information indicates whether a reported capability value set (e.g., ID information) having a smaller value is a subset of a reported capability value set having a larger value, in other words, the reported capability value set having a larger value refers to a simultaneous multi-panel state and the reported capability value set having a smaller value refers to a single-panel state.

[0102] For example, the capability related information indicates capability value set #1 (including capability values ​​of 2-port SRS) and capability value set #2 (including capability values ​​of 2-port SRS), and indicates that capability value set #1 having 2-port SRS is a subset of capability value set #2 having 4-port SRS. Such capability related information means that the terminal device 220 can transmit up to 4-port SRS in simultaneous multi-panel and transmit up to 2-port SRS in single-panel.

[0103] Alternatively or additionally, in some embodiments, the capability-related information may indicate whether the terminal device 220 supports applying two or more capability value sets in parallel. Additionally, the capability-related information may further indicate the number of capability value sets supported to be applied in parallel by the terminal device 220. For example, the capability-related information indicates capability value set #1 (including capability values ​​of a 2-port SRS) and capability value set #2 (including capability values ​​of a 4-port SRS), and capability value sets #1 and #2 can be used simultaneously, which means that the terminal device 220 can support a maximum of 6-port SRS.

[0104] Additionally, the concept of a capability value set status may be introduced. Specifically, the capability value set status may indicate that the capability value set is used for uplink transmission or that the capability value set is used for downlink transmission. Additionally, the capability value set status may indicate some reserved status, for example, the capability value set application status indicating whether the capability value set has already been applied or will be applied. Alternatively or additionally, in some embodiments, the capability value setting status may indicate whether the applied capability value set has been changed or will be changed. In one particular exemplary embodiment, the capability value set status may indicate one of the capability value set being used for uplink, the capability value set being used for downlink (i.e., for downlink panel only / not related to uplink panel), the capability value set not suitable for uplink transmission (i.e., the terminal device 220 cannot use the reported capability value set for uplink transmission), whether the applied capability value set has been changed or will be changed, etc.

[0105] By incorporating the concept of a capability value set state, in some embodiments, the capability-related information may also indicate whether terminal device 220 supports reporting a correspondence report for downlink transmissions. Additionally, the capability-related information may also indicate whether terminal device 220 supports reporting a status of a reserved capability value set.

[0106] As described above, identity information of a capability set may be included in the capability set, and thus the identity information may be used to identify / index the capability set.

[0107] Furthermore, the identity information of the capability value set may be indicated in either an explicit manner or an implicit manner. Specifically, the terminal device may report the explicit identity information (e.g., number / index) of the capability value set to the network device 210. Alternatively, for the implicit manner, the identification information of the capability value set is not necessarily included in the capability-related information. In this case, the number / index of the related capability value set may be implied. In one particular exemplary embodiment, the number / index of the capability value set is determined according to an ascending or descending order based on the number of SRS ports associated with the capability value set. In another particular exemplary embodiment, the number / index of the capability value set is determined according to an ascending or descending order based on the reporting order of the capability value set.

[0108] In some embodiments, the number / index of the capability value sets to be reported / determined may be represented as a bit sequence (e.g., a panel information field) in the correspondence report so that the capability value sets may be indicated / reported to the network device 210. The bit size of the bit sequence included in the correspondence report is determined based on a first number, i.e., L, of capability-related parameter sets supported by the terminal device 220. Specifically, the bit size is calculated as ceil(log2(L)).

[0109] Alternatively or additionally, in some embodiments, the bit size of the bit sequence included in the correspondence report is determined based on a second number of states of the capability set supported by the terminal device 220. In one particular exemplary embodiment, one or more specific indexes / identities, e.g., N, may be assigned to indicate that the capability set is used for downlink, where N may be "1" or other positive integer. Considering such specific indexes, the bit size of the bit sequence included in the correspondence report may be calculated as ceil(log2(L+N)).

[0110] In another particular exemplary embodiment, one or more particular index / identity information values, e.g., M, may be assigned to indicate that the capability value set is to be used for the reserved state, where M may be "1" or other positive integer. Considering such particular indexes, the bit size of the bit sequence included in the correspondence report may be calculated as ceil(log2(L+M)).

[0111] It should be understood that such an indexing mechanism may be used to index any interaction procedure between network device 210 and terminal device 220, for example, a set of capability values ​​contained in a correspondence report as described below.

[0112] Alternatively or in addition, in some embodiments, the capability-related information may indicate other capabilities of the terminal device 220, including, but not limited to, whether the terminal device 220 supports determining the feedback state of a correspondence report, whether the terminal device 220 supports reporting the state of a capability value set, whether the terminal device 220 supports obtaining the correspondence with a time limit, or the number of capability value sets included in a correspondence report supported by the terminal device 220.

[0113] It should be understood that the above illustrated capability-related information is provided for illustrative purposes only and no limitation is to be implied. In some other exemplary embodiments, any suitable capability-related information may be used.

[0114] With continued reference to FIG. 3, the network device 210 sends 320 one or more settings to the end device 220 .

[0115] In one exemplary embodiment, the one or more configurations may be generated based on capability-related information received from terminal device 220. In another exemplary embodiment, the measurement configurations are generated independently of the capability-related information.

[0116] In one exemplary embodiment, the one or more configurations indicate an associative relationship between at least one transmission parameter and a set of capability values.

[0117] An example of a transmission parameter is a resource for transmitting an SRS, such as an SRS resource set and an SRS resource. Specifically, at least one of an SRS resource set, an SRS resource, and an SRS port may be associated with a capability set. For example, the one or more settings associate an SRS resource set #1 with a capability set #1, and the number of ports of the SRS resource in the SRS resource set #1 is less than the number of SRS ports reported in the capability set #1.

[0118] Additionally, in one exemplary embodiment, terminal device 220 performs SRS transmission based on both the at least one configuration and one or more capability sets currently applied in terminal device 220. In other words, terminal device 220 is not expected to transmit all configured SRS resources, but may select SRS resources according to its current panel state (i.e., the currently applied panel).

[0119] Another example of the transmission parameter is a resource for transmitting a PUCCH. Specifically, at least one of a PUCCH resource, a PUCCH resource set, and a PUCCH resource group may be associated with a capability value set.

[0120] Other examples of transmission parameters are the TCI state and resources for transmitting the downlink RS. Specifically, the TCI state, the downlink RS resource / resource set / port may also be associated with a capability value set.

[0121] Table 1 below illustrates an exemplary association relationship between transmission parameters and two capability value sets. Table 1. Exemplary association relationships TIFF2025501592000002.tif85158

[0122] Alternatively or additionally, in some embodiments, the one or more settings indicate a reporting volume of the correspondence report. In other words, the network device 210 may set the content to be included in the correspondence report. By indicating the reporting volume, the network device 210 may instruct the terminal device 220 to report panel information, such as identification information of a capability value set as described above, SSBRI / CRI, RSRP / SINR, associated correspondence, etc.

[0123] Alternatively or additionally, in some embodiments, the one or more configurations indicate a time domain behavior of the correspondence reporting.

[0124] In one particular embodiment, the one or more settings indicate that the correspondence report is a periodic report. Additionally, the period of the correspondence report can be linked to other periodic beam reports without panel information reports. For example, the correspondence report is set to have a first period by the at least one setting, and the first period is aligned with a second period of the beam report, and the first period is a multiple of the second period. In other words, if the beam report is set to have a period T, which is N times (i.e., N*T) the period set for the beam report without panel information (e.g., SSBRI / cri-rsrp / SINR), every N*T beam reports (SSBRI / CRI-RSRP / SINR) can be replaced with a panel information beam report (i.e., a correspondence report).

[0125] In some embodiments, semi-persistent and / or aperiodic time domain behaviors may be configured to be associated with periodic time domain behaviors. Specifically, in some embodiments, triggering of semi-persistent and aperiodic time domain behaviors is conditional. In some embodiments, semi-persistent and / or aperiodic time domain behaviors are triggered / allowed only if periodic time domain behaviors are configured. Additionally, in some embodiments, aperiodic time domain behaviors are triggered / allowed only if semi-persistent time domain behaviors are configured.

[0126] It should be understood that the association / setting restrictions between periodic, semi-persistent and aperiodic time-correlated reporting may be indicated either in an explicit manner (e.g., indicating links between different reports) or in an implicit manner.

[0127] Alternatively or additionally, the one or more settings indicate information about a time limit for obtaining a correspondence report. Alternatively or additionally, the one or more settings indicate a number of capability value sets associated with one correspondence report. Other information indicated by the one or more settings may be described in the following text.

[0128] It should be understood that the above illustrated interaction procedures are given for illustrative purposes only and do not imply any limitations. In some other embodiments, any other suitable interaction procedures may be performed. Exemplary Process for Initial Transmission

[0129] As mentioned above, if the correspondence report is not sent to the network device 210, both the network device 210 and the terminal device 220 do not know which panel / capability value set / beam should be applied. In the following embodiment, this outstanding problem can be well addressed.

[0130] According to some embodiments of the present disclosure, the initial transmission comprises: at least a period between reporting a set of capability scores and sending said first correspondence report; a period of time between an initial access and transmission of said first correspondence report; - a period of time between an initial configuration and the sending of said first correspondence report; or - the period between an initial setup and sending of said first correspondence report.

[0131] It should be understood that the above time periods are given for illustrative purposes only and no limitation is implied. In some other embodiments, the initial transmission may be performed within a suitable time period during which the network device 210 and the terminal device 220 are unaware of the transmission parameters (e.g., panel, capability set, beam, RS, etc.). The present disclosure is not limited in this respect.

[0132] In the particular exemplary embodiment of FIG. 3, during period 370 (i.e., at least the period between reporting the capability value set and transmitting the first correspondence report), terminal device 220 and network device 210 may communicate with each other using a default capability value set 330, which may be referred to as an initial transmission.

[0133] In this way, because network device 210 and terminal device 220 have a common understanding of communication parameters (i.e., capability value set / panel), network device 210 and terminal device 220 can communicate with each other even if a correspondence report has not been sent to network device 210.

[0134] The default performance parameter set may be determined by any suitable policy / rule. In one exemplary embodiment, the performance parameter set with the minimum / maximum / pre-defined index value may be used as the default performance parameter set. Alternatively, in another embodiment, the performance parameter set with the minimum / maximum number of SRS ports may be used as the default performance parameter set. Alternatively, in another embodiment, the performance parameter set with the lower or lowest index value may be used as the default performance parameter set.

[0135] An example of a default ability set is: ● A set of ability scores with lower abilities; ● A set of ability scores with higher abilities; - the ability set having a lower ability set index; ● The ability set with the higher ability set index; ● The last used ability score set, ● A set of predefined ability scores; A set of capability values ​​set by either the terminal device 220 or the network device 210; It is shown as:

[0136] It should be understood that the above-mentioned default capability value set is given for illustrative purposes only and does not imply any limitation. In some other exemplary embodiments, any suitable policy / rule may be applied to determine the default capability parameter set. In other words, it may be any predefined rule known on both the network device 210 side and the terminal device 220 side, or may be signaled to each other by the network device 210 / terminal device 220 via signaling (e.g., configuration / capability related signaling).

[0137] In some embodiments, the terminal device 220 transmits information about the default capability set during a random access (RA) procedure. Specifically, the information about the default capability set is carried on one physical random access channel (PRACH). In one exemplary embodiment, the information about the default capability set is included in message 3 during a four-step RA. Alternatively, in another exemplary embodiment, the information about the default capability set is included in message A during a two-step RA.

[0138] In some embodiments, the network device 210 may generate a scheduling message that is generated according to a default capability set, and in response, the terminal device 220 may transmit an uplink transmission to the network device 220 by applying the default capability set.

[0139] In some embodiments, the scheduling message / uplink transmission is associated with the SRS transmission. Specifically, only the SRS resource set / resource / port associated with the default capability set is scheduled / used / expected. For example, if the terminal device 220 reports two capability sets, namely, capability set #1 corresponding to SRS with up to 2 ports and capability set #2 corresponding to SRS with up to 4 ports, during the initial transmission, if the capability set with the lower capability is assumed as the default capability set, the SRS resource with 4 ports is not scheduled / transmitted. In other words, the terminal device 220 does not expect (or is not expected) to transmit SRS with more than 2 ports.

[0140] Alternatively or additionally, in some embodiments, the scheduling message / uplink transmission is associated with a PUSCH transmission, specifically, only SRS resource sets / resources / ports associated with the default capability set are scheduled / used / assumed.

[0141] For example, if terminal device 220 reports two capability value sets, i.e., capability value set #1 corresponding to a PUSCH with up to two layers and capability value set #2 corresponding to a PUSCH with up to four layers, if the capability value set with the lower capability is assumed as the default capability value set, then during initial transmission, network device 210 should not schedule PUSCH transmission with a number of layers greater than the lower reported value (i.e., two layers), and terminal device 220 does not expect (or is not expected) to transmit a PUSCH with more than two layers.

[0142] Additionally, in some embodiments, during initial transmission, uplink transmission / scheduling may be performed using a spatial domain transmit filter associated with the assumed RS, where the assumed RS should be associated with a default capability value set. In other words, the uplink transmit beam for SRS / PUCCH / PUSCH should be associated with a default capability value set.

[0143] Examples of possible RSs include the last PRACH beam / RS, the RS / beam used for initial access, etc.

[0144] Thus, the original transmission between the terminal device 220 and the network device 210 is well taken care of. Exemplary Process for Obtaining Correspondence Reports

[0145] The terminal device 220 may measure the signal quality of the RS, which may be configured by the network device 210 or depending on the UE implementation, such as RSRP, SINR, coupling loss, path loss, UL transmit power, etc. Then, the terminal device 220 may include such measurement results in the correspondence report. In order to select a more appropriate panel / capability value set and avoid the out-of-date problem of the correspondence report, a configuration on the time limit for obtaining the measurement results / correspondence report may be introduced.

[0146] As previously mentioned, capability related information and settings regarding time limits may be exchanged between the terminal device 220 and the network device 210 .

[0147] Specifically, the network device 210 may transmit information regarding a time restriction for obtaining the correspondence report to the terminal device 220. In one exemplary embodiment, the time restriction may be set by a newly introduced higher layer parameter (represented as timeRestrictionForPanelCorrespondence). Alternatively, in another exemplary embodiment, the time restriction may be set by reusing a conventional parameter (e.g., timeRestrictionForChannelMeasurements, timeRestrictionForInterferenceMeasurements). In some embodiments, the terminal device 220 may report whether a time restriction was applied when obtaining the correspondence report. Specifically, one additional bit may be included in the correspondence report to indicate whether a time restriction was applied when obtaining the correspondence report and whether the reported correspondence report was obtained based on the time restriction.

[0148] Using information about the time limit set by the network device 210, the terminal device 220 may obtain a correspondence report accordingly. Specifically, if the terminal device 220 is not configured to have a time limit, the terminal device 220 should obtain / derive a correspondence report by measuring multiple RSs (e.g., CSI-RS or SSB). Correspondingly, if the terminal device 220 is configured to have a time limit, the terminal device 220 should obtain / derive a correspondence report by measuring only the last RS (the most recent CSI-RS or SSB). Additionally, the RS used to obtain / derive the correspondence report should be earlier than the reference resource.

[0149] In some embodiments, the reference resource is the RS (denoted as Pf) transmitted at the transmission opportunity. In some embodiments, Pf=Pn-Tref, where Tref is predefined or configured by the network device 210 and can have different values ​​depending on the downlink or uplink numerology, carrier aggregation configuration, time domain behavior configuration, time restriction configuration, etc.

[0150] Reference is now made to FIG. 4, which illustrates an interaction timing 400 according to some embodiments of the present disclosure. As illustrated in FIG. 4, before a transmission opportunity (i.e., Pn) for transmitting a correspondence report, there are multiple transmission opportunities (i.e., Pf as illustrated in FIG. 4) for receiving an RS before a reference resource. If the terminal device 220 is not configured to have a time limit, the terminal device 220 may obtain / derive the correspondence report based on multiple RSs (i.e., RSs transmitted at transmission opportunities P0 to Pm). Accordingly, if the terminal device 220 is configured to have a time limit, the terminal device 220 may obtain / derive the correspondence report by measuring only the last RS (i.e., RS transmitted at transmission opportunity Pm).

[0151] In some embodiments, when measuring signal quality, the terminal device 220 may apply two capability value sets (i.e., the currently used capability value set and the new capability value set) and determine whether to report a correspondence report associated with the new capability value set based on the measurement results.

[0152] In one particular exemplary embodiment, the terminal device 220 is currently applying the one or more capability value sets (referred to as old capability value sets) and expects to switch to one or more other capability value sets (referred to as new capability value sets). When measuring RS, the terminal device 220 may activate / apply both the new capability value set and the old capability value set. The terminal device 220 then compares the measurement results on both the new capability value set and the old capability value set and determines whether to report the correspondence associated with the new capability value set.

[0153] Alternatively, the terminal device 220 may apply a new capability value set when measuring the RS, in which case the terminal device 220 compares the measurement results with previous measurement results associated with the old capability value set.

[0154] Additionally, comparison of measurements may be achieved based on criteria related to RSRP, SINR, coupling loss, path loss, unlink transmit power, and the like. Exemplary Process for Generating and Indexing Correspondence Reports

[0155] As described above, the terminal device 220 may send a correspondence report to the network device 210. According to some embodiments of the present disclosure, the correspondence report may include more fields and indicate more information. Furthermore, the identity information may be redefined so that a new capability set state may be introduced. The following text describes more details about the correspondence report.

[0156] In some embodiments, the correspondence report includes identity information for each of the capability score sets represented in the correspondence report.

[0157] As described above, each capability value set may correspond to a panel (physical entity) deployed in the terminal device, a particular panel type, and a status of the capability value set. When reporting capability-related information, the capability value set may be indexed by identity information, where the identity information may be an index of the capability value set, an index of a panel deployed in the terminal device 220, or a status of the capability value set. The indexing mechanism used to report capability-related information as described above can also be used when reporting the correspondence report. For the sake of brevity, similar content is omitted, and some additional functions are described below.

[0158] Additionally, the status of the capability value set may have more diverse definitions. Specifically, the status of the capability value set may indicate that the capability value set is used for the uplink or that the capability value set is used for the downlink. Additionally, the status of the capability value set may indicate some reserved status, for example, the application status of the capability value set indicating whether the capability value set has already been applied or will be applied. Alternatively or additionally, in some embodiments, the status of the capability value setting may indicate whether the applied capability value set has been changed or will be changed. In one particular exemplary embodiment, the status of the capability value set may indicate one of: a capability value set being used for the uplink, a capability value set being used for the downlink (i.e., for the downlink panel only / not associated with the uplink panel), a capability value set not suitable for uplink transmission (e.g., the terminal device 220 cannot use the reported beam for uplink transmission), whether the (activated / applied) uplink capability value set / panel has been changed or whether the (activated / applied) uplink capability value set / panel will be changed, whether the applied capability value set has been changed or will be changed, etc.

[0159] In short, the correspondence report may include a panel information field (i.e., identity information), and further, some values ​​of the panel information field may be reserved and used to indicate newly defined / introduced downlink only states and some reserved states.

[0160] Additionally, the bit size of the panel information field included in the correspondence report may be determined based on at least one of the number of capability value sets, the number of panels deployed in the terminal device 220, and the number of states of the capability value set. In one particular exemplary embodiment, the bit size of the panel information field is determined based on either or both of the number of reserved states and the number of capability value sets.

[0161] Additionally, the reserved states may be selectively reported and configured. Specifically, the terminal device 220 may report which reserved states are supported by the terminal device 220. In response, the network device 210 may enable / disable some of the reserved states.

[0162] In some embodiments, the reserved states may be represented in ascending / descending order.

[0163] In some embodiments, the number of capability value sets associated with one correspondence report may be set. In one particular exemplary embodiment, one correspondence report is associated with one capability value set. Alternatively, one correspondence report is associated with two or more capability value sets.

[0164] In some embodiments, the number of RSs / beams associated with one capability set may also be set. In one particular exemplary embodiment, in the correspondence report, each RS / beam corresponds to one capability set.

[0165] In short, terminal device 220 may generate a correspondence report in an appropriate format. Table 2 below shows four possible formats of the correspondence report. Table 2 shows the four possible formats for correspondence reporting. TIFF2025501592000003.tif97162

[0166] In the above Table 2, "Panel Information" refers to identification information of the capability value set, "SSBRI / CRI" refers to information of the RS / beam, and "RSRP / SINR" refers to the measurement result of the corresponding RS / beam. Additionally or alternatively, the first RSRP / SINR is a 7-bit value, and each of the remaining RSRP / SINRs is represented by a 4-bit differential RSRP / SINR value calculated with reference to the first RSRP / SINR.

[0167] In some embodiments, as seen in format 1 / 2 above, one capability value set corresponds to one RS / beam (i.e., one panel per SSBRI / CRI). By using format 1 / 2, terminal device 220 may report different uplink RS / beam selections for different panels.

[0168] In some embodiments, one correspondence report corresponds to one capability value set, as can be seen from Format 3. Using Format 3, terminal device 220 indicates that all reported SSBRI / CRI (i.e., RS / beams) are available as uplink RS / beams when terminal device 220 uses this panel for uplink transmission.

[0169] In some embodiments, the network device 210 may set the number of capability sets (denoted as "X", where X<the number of capability sets set to be reported) to be included in the correspondence report. For each capability set reported, one or more RSs / beams may be reported. Additionally, the remaining RSs / beams may be used for the downlink. The above Format 4 indicates that the number of capability sets included in one correspondence report is "2".

[0170] In some embodiments, the content or format of the correspondence report may be determined based on a time limit setting. Specifically, when a time limit is applied, only the most recent RS can be used to obtain the correspondence report, and in particular, for a terminal device 220 that cannot support multiple active panels at the same time, only one panel can be used to obtain / derive the correspondence report. In one particular exemplary embodiment, when a time limit is applied when obtaining the correspondence report, the terminal device 220 transmits a correspondence report with one capability value set index, regardless of the set number of capability value set indexes. In another particular example, when a time limit is applied, the terminal device 220 transmits a correspondence report corresponding to one capability value set (e.g., format 3), and when a time limit is not applied, the terminal device 220 transmits a correspondence report in which one capability value set corresponds to one RS / beam (e.g., format 1 / 2) or the set number of capability value sets is included (e.g., format 4).

[0171] In addition to the above, the network device 210 may send a configuration indicating the RS resources to the terminal device 220 in an information element (IE) of "RS resource set". Furthermore, one parameter of "repetition" may be included in the IE of "RS resource set". If the parameter of "repetition" is enabled (i.e., the value of the parameter of repetition is "on"), the network device 210 transmits all CSI-RS resources on the same Tx beam. In other words, there is only one beam for downlink transmission, and the information of the one beam is known to the network device 210. In this case, there is no need to report the RS / beam information to the network device 210. Therefore, some other improvements may be performed by either the network device 210 or the terminal device 220.

[0172] In some embodiments, the terminal device 220 is not expected to be configured to report a correspondence report when the parameter "repetition" included in the RS resource set is enabled / "on". For example, the parameter "report quantity" included in the configuration is used to indicate to the terminal device 220 to report a correspondence report including identity information of the capability value set. In this case, the parameter (report quantity) indicating to report identity information of the capability value set and the "repetition" set as "on" are not enabled / configured to the terminal device 220 at the same time.

[0173] According to some embodiments of the present disclosure, even if the terminal device 220 is configured to report a correspondence relationship report when the “repetition” parameter included in the RS resource set is enabled / “on”, the terminal device 220 can still successfully handle such a scenario, as described below.

[0174] In some embodiments, if the value of the repetition parameter included in the RS resource set is "on", terminal device 220 disables reporting of correspondence reports.

[0175] Alternatively or additionally, in some embodiments, if the value of the repetition parameter included in the RS resource set is "on", the terminal device 220 transmits a correspondence report associated with one RS.

[0176] Alternatively or additionally, in some embodiments, if the value of the repetition parameter included in the RS resource set is “on”, the terminal device 220 transmits a correspondence report with one capability value set index, regardless of the number of capability value set indexes set.

[0177] Alternatively or additionally, in some embodiments, if the value of the repetition parameter included in the RS resource set is "on", the terminal device 220 transmits a correspondence report without including information about the RS.

[0178] Additionally, the correspondence report may include other information / fields. In some embodiments, the terminal device 220 may indicate whether the correspondence was obtained based on a time limit. In one particular exemplary embodiment, the correspondence report includes an indication having one bit, where the indication indicates whether the correspondence report was determined based only on the most recent downlink RS.

[0179] Terminal device 220 may then generate a correspondence report and transmit the correspondence report to network device 210 (340). Example process of the feedback mechanism

[0180] As mentioned above, the correspondence report may cause a change / switch of the panel / beam / RS / capability value set. For this reason, the transmission state of the correspondence report should be aligned between the network device 210 and the terminal device 220. As a result, a feedback mechanism for the correspondence report is needed.

[0181] According to some embodiments of the present disclosure, the terminal device 220 and the network device 210 communicate with each other (350) according to a feedback status of the correspondence report, where the feedback status may be ACK or NACK. Alternatively, the feedback status may be ACK, NACK, or "not transmitted / detected" (i.e., no ACK / NACK). It should be understood that if a feedback mechanism for the correspondence report is introduced, the absence of ACK / NACK should be interpreted as "NACK".

[0182] In order to avoid introducing any new messages / signaling (including a new Radio Network Temporary Identifier RNTI for feedback on correspondence reporting, or a new Downlink Control Information DCI), some existing messages / signaling (hereinafter referred to as feedback messages) may be used to indicate the feedback status.

[0183] An example of a feedback message is a TCI activation command or a TCI indication. Specifically, if the TCI activation command or the TCI indication includes information about a TCI state at least partially associated with at least one RS indicated by the correspondence report, the feedback status of the correspondence report is ACK. Correspondingly, if the TCI activation command or the TCI indication includes information about a TCI state unrelated to the RS indicated by the correspondence report, the feedback status of the correspondence report is NACK. Alternatively, if the TCI activation command or the TCI indication includes information about a TCI state associated with at least one RS having more ports than the maximum SRS port of the capability value set in the correspondence report, the feedback status of the correspondence report is NACK. Additionally, the TCI activation command or the TCI indication is the first one received immediately after the transmission of the correspondence report. Alternatively, the TCI activation command or the TCI indication is the first one received within a certain period of time after the transmission of the correspondence report. In some embodiments, the TCI activation command or the TCI indication is conveyed via MAC CE signaling or DCI. In some embodiments, the TCI activation command or TCI indication includes combined TCI states for both uplink and downlink, or uplink-only TCI states, In some embodiments, the TCI activation command or TCI indication includes TCI states that apply to all physical channels / signals including PDCCH, PDSCH, PUCCH, PUSCH, or that apply only to a subset of physical channels / signals, e.g., PUSCH.

[0184] Another example of a feedback message is a DCI message for scheduling a PUSCH, the DCI message including an SRS resource indicator (SRI). In some embodiments, if the SRI points to an SRS resource that has more ports than the maximum SRS port associated with the capability set in the correspondence report, the feedback status of the correspondence report is NACK, otherwise the feedback status is ACK. In some other embodiments, if the SRI points to an SRS resource that has a number of ports that does not match the maximum SRS port associated with the capability set in the correspondence report, the feedback status of the correspondence report is NACK, otherwise the feedback status is ACK.

[0185] Another example of the feedback message is a DCI message for scheduling a PUSCH, the DCI message including a transmit precoding matrix indicator (TPMI) for the DCI for scheduling a PUSCH. In some embodiments, if the TPMI indicates a layer number that is greater than the maximum SRS port number corresponding to the capability value set in the correspondence report, the feedback status of the correspondence report is NACK, otherwise the feedback status is ACK. Additionally, the DCI for scheduling a PUSCH is the first one received immediately after the transmission of the correspondence report. Alternatively, the DCI for scheduling a PUSCH is the first one received within a certain period after the transmission of the correspondence report.

[0186] Another example of the feedback message is a PDCCH order for triggering an RA / RACH procedure. Specifically, since the RA procedure may be used for timing alignment of the capability set / panel associated with the reported correspondence report, a PDCCH order may be used to indicate that the status of the correspondence report is ACK. Additionally, after receiving the PDCCH order, the terminal device 220 transmits a RACH together with the reported panel in the correspondence report. Additionally, the PDCCH order is the first one received immediately after the transmission of the correspondence report. Alternatively, the PDCCH order is the first one received within a certain period after the transmission of the correspondence report.

[0187] Another example of a feedback message is a signaling for controlling the transmission power of the terminal device 220. Specifically, the signaling for controlling the transmission power may be used to indicate that the status of the correspondence report is ACK. In one particular exemplary embodiment, the signaling for controlling the transmission power includes a transmit power control (TPC) field for TPC for SRS / PUCCH / PUSCH that triggers a power adjustment for the panel / capability value set associated with the correspondence report. Additionally, in some embodiments, the signaling for controlling the transmission power is a DCI message having a format 2-2 or 2-3 for TPC without uplink grant. Additionally, the signaling for controlling the transmission power is the first one received immediately after the transmission of the correspondence report. Alternatively, the signaling for controlling the transmission power is the first one received within a certain period after the transmission of the correspondence report.

[0188] Another example of the feedback message is a message that triggers the terminal device 220 to report a correspondence report. In one particular exemplary embodiment, the message used to trigger the activation of the aperiodic correspondence report or the semi-persistent correspondence report is used to indicate that the status of the correspondence report is NACK. For example, the periodic correspondence report is configured, but the network device 210 fails to receive the expected periodic correspondence report. Therefore, the network device 210 may send a message that triggers the terminal device 220 to report the aperiodic correspondence report or the semi-persistent correspondence report. Thus, the message implies a failed transmission of the periodic correspondence report indicating the NACK status.

[0189] Another example of the feedback message is a message for activating SRS transmission. Specifically, the aperiodic or semi-persistent SRS transmission associated with the capability value set may be used to train the uplink codebook, the precoder used for the non-codebook-based uplink transmission, or the uplink beam for the capability value set associated with the correspondence report. In some embodiments, the SRS transmission may be the SRS resource set / resource / port associated with the corresponding capability value set, as shown in Table 1. Thus, the message for activating SRS transmission may be used to indicate the ACK state.

[0190] Another example of the feedback message is a message for activating CSI report transmission. Specifically, aperiodic or semi-persistent CSI reporting may be used to train a downlink receive beam associated with a capability value set. Additionally, the triggered / activated CSI reporting may be configured to disable reporting of identity information of the capability value set (i.e., the parameter of "report quantity" is set to be "none") and the parameter of repetition within resource set is set to be "on". In some embodiments, the CSI report transmission may be based on the downlink RS resources associated with the corresponding capability value set, as shown in Table 1.

[0191] In order to reduce signaling overhead, the correspondence report may be conditionally transmitted / received, in other words, in some scenarios, the terminal device 220 does not expect to receive a feedback message, and the network device 210 does not transmit a feedback message.

[0192] In some embodiments, the feedback message is sent / received only if the reported correspondence report is at least partially different from the previous correspondence report, in other words, the reported correspondence report may update the previous correspondence report.

[0193] In one particular exemplary embodiment, a correspondence report indicating a correspondence between at least one first set of capability values ​​and at least one first RS is reported from terminal device 220 to network device 210. In some embodiments, a feedback message is sent / received when the at least one correspondence is at least partially different from a second correspondence, the second correspondence being currently applied in terminal device 220 or associated with the last correspondence report.

[0194] Alternatively or additionally, in some other embodiments, the feedback message is sent / received when at least one first capability value set associated with the correspondence report differs at least in part from the at least one second capability value set currently applied in the terminal device 220 or associated with the last correspondence report.

[0195] Alternatively or additionally, in some other embodiments, the feedback message is transmitted / received when at least one first RS associated with the correspondence report is at least partially different from the at least one second RS, which is currently being used in the terminal device 220 or is associated with the last correspondence report.

[0196] Furthermore, two or more second correspondence reports may be taken into consideration when determining whether to send / receive a feedback message, where the second correspondence report may refer to one or more correspondence reports sent within a certain time interval.

[0197] Alternatively or additionally, in some other embodiments, a feedback message is sent / received when the correspondence reporting is configured to have a specific time domain behavior. In other words, a feedback message is not sent / received when the correspondence reporting is configured to have a specific time domain behavior. In particular, periodic feedback is not preferred due to the larger signaling overhead it may cause. In some embodiments, a feedback message is not sent / received when the correspondence reporting is periodic. In some embodiments, when both periodic correspondence reporting and aperiodic / semi-persistent correspondence reporting are configured, a feedback message is not sent / received for periodic correspondence reporting.

[0198] In some embodiments, update / override rules may be defined when determining whether to send / receive a feedback message.

[0199] In one particular exemplary embodiment, the comparison of the correspondence report with the at least one second correspondence report (e.g., a currently applied correspondence report, a last correspondence report, or a correspondence report sent within a certain time interval) is performed only if the correspondence report and the at least one second correspondence report are configured to have the same time domain behavior (e.g., periodic, aperiodic, and semi-persistent).

[0200] Alternatively or additionally, in another particular exemplary embodiment, whether to send / receive a feedback message may be determined based on a priority of the time domain behaviors. One example of a priority is aperiodic time domain behavior, semi-persistent time domain behavior / periodic time domain behavior. Another example of a priority is periodic time domain behavior, aperiodic time domain behavior / semi-persistent time domain behavior. Another example of a priority is aperiodic time domain behavior, semi-persistent time domain behavior, and periodic time domain behavior. Another example of a priority is periodic time domain behavior, aperiodic time domain behavior, and semi-persistent time domain behavior. In other embodiments, other priorities may be applied.

[0201] Alternatively or additionally, in some other embodiments, whether to send / receive a feedback message is determined based on identity information of the capability value set associated with the correspondence report. Specifically, the feedback message is sent / received if the identity information indicates a status of a particular capability value set. In one particular exemplary embodiment, the feedback message is sent / received if the identity information indicates that the capability value set is used for the uplink. Alternatively, in another particular exemplary embodiment, the feedback message is sent / received if the identity information indicates that the capability value set is not used for the downlink. Alternatively, in another particular exemplary embodiment, the feedback message is sent / received if the identity information indicates a status of not reserved.

[0202] In some embodiments, the message is sent / received within a certain period after the correspondence report. In other words, if the terminal device 220 fails to receive the feedback message within a certain period after sending the correspondence report, the terminal device 220 determines the feedback status to be NACK.

[0203] In this way, the signaling overhead caused by the feedback mechanism is minimized.

[0204] In addition to the above, operations on a newly reported capability set should be aligned in both the terminal device 220 and the network device 210 .

[0205] In some embodiments, the operation of applying the newly reported capability set is controlled by the network device 210 .

[0206] In one particular exemplary embodiment, the newly reported capability set is applied in response to sending a feedback message about the correspondence report.

[0207] Alternatively, in another particular exemplary embodiment, the newly reported set of capability values ​​is applied in response to an SRS transmission from terminal device 220 to network device 210 after receiving the feedback message.

[0208] Alternatively, in some embodiments, operations on the newly reported capability set are controlled by terminal 220 .

[0209] In one particular exemplary embodiment, in response to sending a correspondence report, the newly reported set of capability scores is applied.

[0210] Alternatively, in another particular exemplary embodiment, the newly reported set of capability values ​​is applied depending on the time since sending the correspondence report exceeding a preset period of time.

[0211] Additionally, in some embodiments, when there are multiple RSs indicated by the first correspondence relationship, the terminal device 220 transmits an uplink transmission with a spatial domain transmit filter associated with an RS having the best signal quality among the multiple RSs.

[0212] Additionally, if the operation of applying the newly reported capability value set is controlled by the terminal device 220 and a failed transmission of the correspondence report occurs, the terminal device 220 should fall back to a previous operation state. Specifically, if the terminal device 220 fails to receive a feedback message indicating an ACK for the correspondence report or a feedback message indicating a NACK for the correspondence report, the terminal device 200 disables application of the newly reported capability value set.

[0213] In addition to the above, the operations for the currently used capability set (also referred to as the second capability set) should also be aligned in both the terminal device 220 and the network device 210 .

[0214] In some embodiments, the second set of capability scores continues to be applied after a period of time following sending the correspondence report.

[0215] Alternatively, in some other embodiments, the second set of capability values ​​continues to be applied until a message is received from the network device 210 indicating an ACK for the correspondence report.

[0216] Alternatively, in some other embodiments, the second set of capability values ​​continues to be applied until a message is received from the network device 210 indicating an ACK for the correspondence report.

[0217] Alternatively, in some other embodiments, the second capability value set continues to be applied until the next transmission opportunity for the correspondence report, in other words, until transmitting another correspondence report to the network device 210.

[0218] Additionally, the transmit power of terminal device 220 is controlled by network device 210. Specifically, the transmit power of terminal device 220 may operate in an accumulation mode, in which terminal device 220 maintains an accumulated power control adjustment state and adjusts the transmit power according to TPC commands from network device 210.

[0219] According to some embodiments of the present disclosure, terminal device 220 resets its accumulation of power control adjustment states in response to applying the newly reported correspondence.

[0220] For better understanding, some exemplary operations are described with reference to the following two specific embodiments and FIG. 5, where FIG. 5 illustrates an interaction timing 500 according to some embodiments of the present disclosure. Some exemplary operations for one particular exemplary embodiment

[0221] In this particular exemplary embodiment, the operation of applying the newly reported capability set is controlled by the network device 210 .

[0222] 5, first, the terminal device 220 and the network device 210 apply a second capability value set. Then, the terminal device 220 sends a correspondence report to the network device 210 at time T1, and receives a feedback message at time T2. Furthermore, time T3 refers to the first transmission opportunity for the SRS after receiving the feedback message.

[0223] In some embodiments, after sending the correspondence report to the network device 210 at time T1, the terminal device 220 keeps the newly reported one activated for a while so that the terminal device 220 can switch to the newly reported one.

[0224] In some embodiments, terminal device 220 keeps the newly reported correspondence report activated for a preset period of time after sending the correspondence report.

[0225] Alternatively, in some embodiments, the terminal device 220 keeps the newly reported one activated until the next transmission opportunity for the correspondence report, which includes a periodic correspondence report, an aperiodic correspondence report, or a semi-persistent correspondence report.

[0226] Alternatively, in some embodiments, terminal device 220 keeps the newly reported one activated until sending a feedback message. As shown in FIG. 5, terminal device 220 keeps the newly reported one activated until time T2.

[0227] In the embodiment of FIG. 5, the operation of applying the newly reported capability value set is controlled by the network device 210 .

[0228] In some embodiments, the terminal device 220 and the network device 210 apply the newly reported capability value set after sending the feedback message. As shown in FIG. 5, the terminal device 220 and the network device 210 start applying the newly reported capability value set from time T2. Additionally, an offset (e.g., X time units) may be applied. In other words, the start time of applying the newly reported capability value set is X time units after time T2.

[0229] In some embodiments, the terminal device 220 resets the accumulation of power control adjustment states in response to applying the newly reported capability value set. Specifically, when the newly reported capability value set is applied (i.e., immediately after an uplink panel switch), the TPC control should not be accumulated regardless of the power setting. In one particular exemplary embodiment, the terminal device 220 resets the accumulation of PUSCH / PUCCH / SRS power control adjustment state 1 or all states or a subset of states associated with the newly reported capability value set. Optionally, the instruction in the TPC command field may represent an absolute value or an accumulated value. In one particular exemplary embodiment, a 0 in the TPC command field may represent -4db as an absolute value and -1db as an accumulated value. In another particular embodiment, the terminal device 220 applies the absolute value according to the instruction in the TPC command field regardless of the power setting. In other words, the terminal device 220 does not apply the accumulated value according to the instruction in the TPC command field regardless of the power setting.

[0230] The operation for the second ability score set currently being used is described as follows.

[0231] In some embodiments, the terminal device 220 and the network device 210 continue to apply the second set of capability values ​​until they apply the newly reported set of capability values. Additionally, an offset (e.g., X time units) may be considered.

[0232] Furthermore, the SRS is used to train the uplink beam / precoder / codebook associated with the newly reported capability value set. Before obtaining the trained result, the terminal device 220 may not be able to use the newly reported capability value set. Therefore, in some embodiments, the terminal device 220 and the network device 210 continue to apply the second capability value set until the first SRS transmission (i.e., time T3). Alternatively, in some embodiments, after the feedback message is received, a different panel / beam assumption is applied to the PUCCH / PUSCH transmission before the first SRS transmission (i.e., time T3).

[0233] Additionally, the triggering / activation of SRS transmission is conditional. Specifically, if the feedback message indicates NACK, the terminal device 220 does not trigger / activate SRS transmission (i.e., does not trigger / activate SRS transmission at time T3). Some exemplary operations relating to another specific exemplary embodiment

[0234] 5, first, the terminal device 220 and the network device 210 apply a second capability value set. Then, the terminal device 220 sends a correspondence report to the network device 210 at time T1, and receives a feedback message at time T2.

[0235] In some embodiments, terminal device 220 receives a feedback message using a downlink panel corresponding to the newly reported capability set, and if the feedback message is a TCI activation command, terminal device 220 applies the reported capability set using the indicated TCI.

[0236] In this particular exemplary embodiment, the operation of applying the newly reported capability value set is controlled by terminal device 220, which means that the newly reported capability value set is applied before time T2.

[0237] Additionally, terminal device 220 may report RS / beam information (e.g., reported SSBRI / CRI for uplink transmission) to apply the newly reported capability value set.

[0238] Alternatively, the assumed RS / beam may be used when applying the newly reported capability set. In one particular exemplary embodiment, if more than one SSBRI / CRI (RS / beam information) is reported, some rules for selecting the RS / beam may be predefined, for example specifying that the SSBRI / CRI with the best reported RSRP / SINR should always be applied.

[0239] In some embodiments, the terminal device 220 and the network device 210 apply the newly reported capability value set when sending the correspondence report. As shown in FIG. 5, the terminal device 220 and the network start applying the newly reported capability value set from time T1. Additionally, an offset (e.g., X time units) may be applied. In other words, the start time of applying the newly reported capability value set is X time units after time T1.

[0240] The operation for the second ability score set currently being used is described as follows.

[0241] In some embodiments, the terminal device is required to keep the currently used second set of capability values ​​activated for a period of time (eg, a predefined period of time).

[0242] In some embodiments, the terminal device 220 and the network device 210 continue to apply the second set of capability values ​​until they apply the newly reported set of capability values. Additionally, an offset (e.g., X time units) may be considered.

[0243] Further, a power control operation is performed in terminal device 220. Specifically, terminal device 220 resets the accumulation of power control adjustment states in response to applying the newly reported capability value set. Specifically, when the newly reported capability value set is applied (i.e., immediately after an uplink panel switch), TPC control should not be accumulated regardless of the power setting. In one particular exemplary embodiment, terminal device 220 resets the accumulation of PUSCH / PUCCH / SRS power control adjustment state 1 or all states or a subset of states associated with the newly reported capability value set.

[0244] Additionally, as described above, if the terminal device 220 fails to receive a feedback message indicating an ACK for the correspondence report or a feedback message indicating a NACK for the correspondence report, the terminal device 200 disables application of the newly reported capability value set. In this case, TPC commands should not be accumulated by the terminal device 220.

[0245] Optionally, the instruction in the TPC command field may represent an absolute value or a cumulative value. In one particular example embodiment, a 0 in the TPC command field may represent -4db as an absolute value and -1db as a cumulative value. In another specific embodiment, the terminal device 220 applies the absolute value according to the instruction in the TPC command field regardless of the power setting. In other words, the terminal device 220 does not apply the cumulative value according to the instruction in the TPC command field regardless of the power setting. Example process of the feedback mechanism

[0246] As mentioned above, after sending the correspondence report, in some specific scenarios, the terminal device 220 and the network device 210 may need to communicate with each other using a default set of capability values.

[0247] Continuing to refer to FIG. 3, if a fallback condition is met, the terminal device 220 and the network device 210 fall back to applying a default set of capability values ​​(360).

[0248] Some detailed operations will be described with reference to Figures 6A and 6B. In the specific example of Figures 6A and 6B, T1 indicates a time for sending a correspondence report, and T2 indicates an expected time for receiving a feedback message about the correspondence report. It should be understood that the fallback operation does not depend on the feedback mechanism described above.

[0249] In accordance with this disclosure, the time for applying the default capability score set may be defined by any suitable fallback condition.

[0250] In some embodiments, the terminal device 220 determines that the fallback condition is met when the time period since the terminal device 220 transmits the correspondence report exceeds a predefined period. In other words, the terminal device 220 and the network device 210 fall back to applying the default capability value set after a certain period (time interval 610 as shown in FIG. 6B) since the terminal device 220 transmits the correspondence report. As shown in FIG. 6A, the terminal device 220 and the network device 210 fall back to applying the default capability value set at time T3. As can be seen, the implementation of this embodiment is independent of the feedback mechanism.

[0251] Alternatively, in some embodiments, the terminal device 220 determines that the fallback condition is met if the terminal device 220 fails to receive a message indicating an ACK for the correspondence report after a certain period of time after transmitting the correspondence report.

[0252] Alternatively, in some embodiments, terminal device 220 determines that the fallback condition is met when terminal device 220 fails to receive a message indicating an ACK for the correspondence report at a transmission opportunity for receiving the message after a certain period of time (time interval 660 as shown in FIG. 6B) after transmitting the correspondence report. As shown in FIG. 6B, terminal device 220 and network device 210 fall back to applying the default capability value set at time T4.

[0253] Alternatively, in some embodiments, terminal device 220 determines that the fallback condition is met if terminal device 220 receives a message indicating a NACK for the correspondence report.

[0254] Alternatively, in some embodiments, terminal device 220 determines that the fallback condition is met if the capability value set associated with the correspondence report is set to have a higher capability.

[0255] Alternatively, in some embodiments, terminal device 220 determines that the fallback condition is met if the correspondence reports are aperiodic.

[0256] Alternatively, in some embodiments, terminal device 220 determines that a fallback condition is met if a BWP switch, a CC switch, secondary cell activation, and cross cell scheduling occur.

[0257] Alternatively, in some embodiments, terminal device 220 determines that the fallback condition is met if terminal device 220 operates in a power saving mode (eg, DRX mode).

[0258] Alternatively, in some embodiments, terminal device 220 determines that the fallback condition is met if a new capability set / RS / beam is reported via a correspondence report.

[0259] It should be understood that the above examples for determining whether a fallback condition is met can be used separately or in combination. Additionally, in some other embodiments, any suitable rules and factors may be used to determine whether a fallback condition is met.

[0260] Additionally, the definition of the default capability set (i.e., which capability set may be used as the default capability set) is the same as that described for the initial transmission in this disclosure. For the sake of brevity, some content is omitted here. Example method

[0261] 7 is a flow chart of an example method 700 according to some embodiments of the present disclosure. For example, the method 700 may be implemented in the terminal device 220 as shown in FIG.

[0262] At block 710, the terminal device 220 transmits a correspondence report to the network device 210 indicating a first correspondence between the at least one first set of capability values ​​and the at least one first RS.

[0263] In block 720, the terminal device 220 communicates with the network device 210 according to the feedback status of the correspondence report, where the feedback status is one of: ACK or NACK.
