[0001] The disclosure relates generally to wireless communications, including but not limited to systems and methods for prediction of channel state information (CSI) related information (e.g., signal to interference plus noise ratio (SINR) , reference signal received power (RSRP) , or channel quality indicator (CQI) ) and invalidity indication.BACKGROUND
[0002] The standardization organization Third Generation Partnership Project (3GPP) is currently in the process of specifying a new Radio Interface called 5G New Radio (5G NR) as well as a Next Generation Packet Core Network (NG-CN or NGC) . The 5G NR will have three main components: a 5G Access Network (5G-AN) , a 5G Core Network (5GC) , and a User Equipment (UE) . In order to facilitate the enablement of different data services and requirements, the elements of the 5GC, also called Network Functions, have been simplified with some of them being software based so that they could be adapted according to need.SUMMARY
[0003] The example embodiments disclosed herein are directed to solving the issues relating to one or more of the problems presented in the prior art, as well as providing additional features that will become readily apparent by reference to the following detailed description when taken in conjunction with the accompany drawings. In accordance with various embodiments, example systems, methods, devices and computer program products are disclosed herein. It is understood, however, that these embodiments are presented by way of example and are not limiting, and it will be apparent to those of ordinary skill in the art who read the present disclosure that various modifications to the disclosed embodiments can be made while remaining within the scope of this disclosure.
[0004] At least one aspect is directed to a system, a method, an apparatus, or a computer-readable medium for prediction of CSI-related information (e.g., SINR, RSRP, or CQI) and invalidity indication. A wireless communication device (e.g., UE, terminal) may receive from a wireless communication node (e.g., base station, TRP) a channel state information (CSI) reporting setting. The wireless communication device may transmit to the wireless communication node at least one predicted quantity based on the CSI reporting setting. The CSI reporting setting is associated with a first set of one or more resource settings for at least one of channel measurement or interference measurement, and a second set of one or more resource settings for reporting the at least one predicted quantity or for at least one of channel measurement or interference measurement.
[0005] At least one aspect is directed to a system, a method, an apparatus, or a computer-readable medium for prediction of CSI-related information (e.g., SINR, RSRP, or CQI) and invalidity indication. A wireless communication node may transmit to a wireless communication device, a channel state information (CSI) reporting setting. The wireless communication node may receive from the wireless communication device at least one predicted quantity based on the CSI reporting setting. The CSI reporting setting can be associated with a first set of one or more resource settings for at least one of channel measurement or interference measurement and a second set of one or more resource settings for reporting the at least one predicted quantity or for at least one of channel measurement or interference measurement.
[0006] In some implementations, the first set of one or more resource settings comprises at least one of a resource setting for channel measurement; a resource setting for channel measurement and interference measurement; a first resource setting for channel measurement and a second resource setting for interference measurement; or a third resource setting for channel measurement, a fourth resource setting for interference measurement, and / or a fifth resource setting for interference measurement.
[0007] In some implementations, each channel measurement resource for the first resource setting for channel measurement is associated with an interference measurement resource for the second resource setting for interference measurement, according to an order of the channel measurement resource in a channel measurement resource set for the first resource setting for channel measurement and / or an order of the interference measurement resource in a interference measurement resource set for the second resource setting for interference measurement.
[0008] In some implementations, each channel measurement resource for the third resource setting for channel measurement is resource-wise associated with an interference measurement resource for the fourth resource setting for interference measurement, according to an order of the channel measurement resource in a channel measurement resource set for the third resource setting for channel measurement and / or an order of the interference measurement resource in an interference measurement resource set for the fourth resource setting for interference measurement. In some implementations, each channel measurement resource for the third resource setting for channel measurement is resource-wise associated with an interference measurement resource for the fifth resource setting for interference measurement, according to an order of the channel measurement resource in a channel measurement resource set for the third resource setting for channel measurement and / or an order of the interference measurement resource in an interference measurement resource set for the fifth resource setting for interference measurement. In some implementations, each interference measurement resource for the fourth resource setting for interference measurement is resource-wise associated with an interference measurement resource for the fifth resource setting for interference measurement, according to an order of the interference measurement resource in an interference measurement resource set for the fourth resource setting for interference measurement and / or an order of the interference measurement resource in an interference measurement resource set for the fifth resource setting for interference measurement.
[0009] In some implementations, a channel measurement resource for the first resource setting for channel measurement and an interference measurement resource for the second resource setting for interference measurement are quasi-co-located (QCLed) with respect to “typeD. ” In some implementations, a channel measurement resource for the third resource setting for channel measurement, an interference measurement resource for the fourth resource setting for interference measurement, and / or an interference measurement resource for the fifth resource setting for interference measurement are QCLed with respect to the “typeD. ” In some implementations, the wireless communication device is not expected or necessary to measure resources in the second set of one or more resource settings. In some implementations, the second set of one or more resource settings comprises at least one of a resource setting for predicted quantity reporting, a first resource setting, or a second resource setting. In some implementations, each first resource from a first resource set associated with the first resource setting corresponds to a second resource from a second resource set associated with the second resource setting, according to an order of the first resource in the first resource set and / or an order of the second resource in the second resource set.
[0010] In some implementations, the first resource and the second resource are QCLed with respect to “typeD. ” In some implementations, the at least one predicted quantity comprises at least one of a predicted CSI-reference signal (CSI-RS) resource indicator (CRI) or synchronization signal block resource indicator (SSBRI) or a predicted CSI-related information. In some implementations, the predicted CRI or SSBRI, k, corresponds to a (k+1) -th entry of resources in a corresponding resource set associated with the first or second set of one or more resource settings, k being an integer no smaller than 0. In some implementations, the predicted CSI-related information comprises a predicted layer 1 signal to interference plus noise ratio (L1-SINR) or a predicted layer 1 reference signal received power (L1-RSRP) . In some implementations, the at least one predicted quantity is determined based on at least one of: the at least one of channel measurement or interference measurement performed by the wireless communication device according to the first set of one or more resource settings, or predictions performed by the wireless communication device for configured resources associated with the second set of one or more resource settings. In some implementations, the wireless communication device is configured with one or more associated identifiers (IDs) .
[0011] In some implementations, the wireless communication device is configured with a first associated ID and a second associated ID. In some implementations, the first associated ID is associated with a first resource set of the first set of one or more resource settings, and the second associated ID is associated with a second resource set of the second set of one or more resource settings. In some implementations, the wireless communication device is configured with only one associated ID. In some implementations, the only one associated ID is associated with a resource set of the second set of one or more resource settings.
[0012] In some implementations, all reference signals (RSs) for determining a QCL assumption for first resources in a resource set of the first set of one or more resource settings is same as, a subset of, among, or mapped to all RSs for determining the QCL assumption for second resources in the resource set of the second set of one or more resource settings. In some implementations, a resource set of the first set of one or more resource settings is same as, a subset of, among, or mapped to the resource set of the second set of one or more resource settings. In some implementations, when different resource sets are associated with a same associated ID, at least one of resources from the different resource sets can share same or substantially similar properties or a same or substantially similar downlink spatial transmitter (Tx) filter for resources or resource sets among those different resource sets; or a same or substantially similar spatial receiver (Rx) parameter may be used by the wireless communication device for measurement on the resources from those different resource sets.
[0013] In some implementations, the wireless communication device may transmit to the wireless communication node a performance indicator that indicates whether the at least one predicted quantity is valid or at least partially invalid. In some implementations, the wireless communication node may receive from the wireless communication device a performance indicator that indicates whether the at least one predicted quantity is valid or at least partially invalid.
[0014] In some implementations, the performance indicator is associated with at least one of: each of the at least one predicted quantity; at least a portion of the at least one predicted quantity corresponding to a same time instance, or time interval associated with the CSI reporting setting; or the at least one predicted quantity. In some implementations, the at least one predicted quantity comprises a predicted CSI-reference signal (CSI-RS) resource indicator (CRI) or synchronization signal block resource indicator (SSBRI) , and wherein the predicted CRI or SSBRI is designated to be a value indicating that the at least one predicted quantity is invalid or at least partially invalid, or at least a portion of the at least one predicted quantity is invalid, or one of the at least one predicted quantity is invalid.
[0015] In some implementations, the one of the at least one predicted quantity comprises at least one of: a corresponding CRI, a corresponding SSBRI, and / or a corresponding predicted CSI-related information. In some implementations, the portion of the at least one predicted quantity corresponds to a same time instance or time interval associated with the CSI reporting setting. In some implementations, the value is the same as or greater than a number of resources in a resource set of the first or second set of one or more resource setting. In some implementations, a bit-width of the predicted CRI or SSBRI is an integer that is equal to or no smaller than log2 (M+1) , M being the number of resources in the resource set of the first or second set of one or more resource setting.
[0016] In some implementations, the at least one predicted quantity comprises a first predicted CSI-reference signal (CSI-RS) resource indicator (CRI) or synchronization signal block resource indicator (SSBRI) and a second CRI or SSBRI, and wherein the first CRI or SSBRI has a same value as the second CRI or SSBRI, indicating the at least one predicted quantity is invalid or at least partially invalid, or at least a portion of the at least one predicted quantity is invalid. In some implementations, the first CRI or SSBRI and the second CRI or SSBRI are invalid, or wherein the portion of the at least one predicted quantity corresponds to a same time instance or time interval associated with the CSI reporting setting.BRIEF DESCRIPTION OF THE DRAWINGS

[0025] For example, the BS 102 may operate at an allocated channel transmission bandwidth to provide adequate coverage to the UE 104. The BS 102 and the UE 104 may communicate via a downlink radio frame 118, and an uplink radio frame 124 respectively. Each radio frame 118 / 124 may be further divided into sub-frames 120 / 127 which may include data symbols 122 / 128. In the present disclosure, the BS 102 and UE 104 are described herein as non-limiting examples of “communication nodes, ” generally, which can practice the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communications, in accordance with various embodiments of the present solution.
[0026] FIG. 2 illustrates a block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. The system 200 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 of FIG. 1, as described above.
[0027] System 200 generally includes a base station 202 (hereinafter “BS 202” ) and a user equipment device 204 (hereinafter “UE 204” ) . The BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected with one another as necessary via a data communication bus 220. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected with one another as necessary via a data communication bus 240. The BS 202 communicates with the UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for transmission of data as described herein.
[0028] As would be understood by persons of ordinary skill in the art, system 200 may further include any number of modules other than the modules shown in FIG. 2. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software can depend upon the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a suitable manner for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure
[0029] In accordance with some embodiments, the UE transceiver 230 may be referred to herein as an “uplink” transceiver 230 that includes a radio frequency (RF) transmitter and a RF receiver each comprising circuitry that is coupled to the antenna 232.

Similarly, in accordance with some embodiments, the BS transceiver 210 may be referred to herein as a “downlink” transceiver 210 that includes a RF transmitter and a RF receiver each comprising circuity that is coupled to the antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in time duplex fashion. The operations of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operations of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 at the same time that the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is close time synchronization with a minimal guard time between changes in duplex direction.
[0030] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via the wireless data communication link 250, and cooperate with a suitably configured RF antenna arrangement 212 / 232 that can support a particular wireless communication protocol and modulation scheme. In some illustrative embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as the Long Term Evolution (LTE) and emerging 5G standards, and the like. It is understood, however, that the present disclosure is not necessarily limited in application to a particular standard and associated protocols. Rather, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternate, or additional, wireless data communication protocols, including future standards or variations thereof.
[0031] In accordance with various embodiments, the BS 202 may be an evolved node B (eNB) , a serving eNB, a target eNB, a femto station, or a pico station, for example. In some embodiments, the UE 204 may be embodied in various types of user devices such as a mobile phone, a smart phone, a personal digital assistant (PDA) , tablet, laptop computer, wearable computing device, etc. The processor modules 214 and 236 may be implemented, or realized, with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. In this manner, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, or the like. A processor may also be implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.
[0032] Furthermore, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in firmware, in a software module executed by processor modules 214 and 236, respectively, or in any practical combination thereof. The memory modules 216 and 234 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 may be coupled to the processor modules 210 and 230, respectively, such that the processors modules 210 and 230 can read information from, and write information to, memory modules 216 and 234, respectively. The memory modules 216 and 234 may also be integrated into their respective processor modules 210 and 230. In some embodiments, the memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions to be executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by the processor modules 210 and 230, respectively.
[0033] The network communication module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bi-directional communication between base station transceiver 210 and other network components and communication nodes configured to communication with the base station 202. For example, network communication module 218 may be configured to support internet or WiMAX traffic. In a typical deployment, without limitation, network communication module 218 provides an 802.3 Ethernet interface such that base station transceiver 210 can communicate with a conventional Ethernet based computer network. In this manner, the network communication module 218 may include a physical interface for connection to the computer network (e.g., Mobile Switching Center (MSC) ) . The terms “configured for, ” “configured to” and conjugations thereof, as used herein with respect to a specified operation or function, refer to a device, component, circuit, structure, machine, signal, etc., that is physically constructed, programmed, formatted and / or arranged to perform the specified operation or function.
[0034] The Open Systems Interconnection (OSI) Model (referred to herein as, “open system interconnection model” ) is a conceptual and logical layout that defines network communication used by systems (e.g., wireless communication device, wireless communication node) open to interconnection and communication with other systems. The model is broken into seven subcomponents, or layers, each of which represents a conceptual collection of services provided to the layers above and below it. The OSI Model also defines a logical network and effectively describes computer packet transfer by using different layer protocols. The OSI Model may also be referred to as the seven-layer OSI Model or the seven-layer model. In some embodiments, a first layer may be a physical layer. In some embodiments, a second layer may be a Medium Access Control (MAC) layer. In some embodiments, a third layer may be a Radio Link Control (RLC) layer. In some embodiments, a fourth layer may be a Packet Data Convergence Protocol (PDCP) layer. In some embodiments, a fifth layer may be a Radio Resource Control (RRC) layer. In some embodiments, a sixth layer may be a Non Access Stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer being the other layer. 2. Systems and Methods for prediction of CSI-related information and invalidity indication
[0035] For reporting quantity prediction at the UE side, the UE can be provided a CSI reporting setting, where the CSI reporting setting is linked with a first one or multiple resource settings for channel measurement and / or for interference measurement, and a second one or multiple resource settings for predicted quantity reporting. The reporting quantity is configured to be at least one of: predicted CRI, predicted SSBRI, or predicted CSI-related information (e.g., SINR, RSRP, or CQI) . ● The first one or multiple resource settings can include at least one of: one resource setting for channel and interference measurement, one resource setting for channel measurement, one resource setting for interference measurement. The UE may assume that the channel measurement resource and the interference measurement resource configured for one CSI reporting are resource-wise associated and QCLed with respect to ‘typeD’ . ● The second one or multiple resource settings can include at least one of: one resource setting for channel and interference measurement, one resource setting for channel measurement, one resource setting for interference measurement, or one resource setting for predicted quantity reporting. The UE is not expected to measure the resources in the second one or multiple resource settings. ● The UE shall / can determine the reported predicted CRI, predicted SSBRI, and / or predicted CSI-related information based on: measurements for the configured measurement resources associated with the first one or multiple resource settings, and / or prediction for the configured prediction resources associated with the second one or multiple resource settings. ● If only one associated ID is configured, it is associated with the resource sets of the second one or multiple resource settings. And the UE can expect that all RS for determining QCL assumption for the corresponding resources in the resource set of the first one or multiple resource settings are among or mapped to RS for determining QCL assumption for the corresponding resources in the resource set of the second one or multiple resource settings. ● The UE shall / can indicate in the UE reporting whether the reported CSI information is invalid or not. ■ The UE shall / can report performance indicator to indicate whether the corresponding CSI information is valid or not. The performance indicator can be reported per beam, per time instance, or per CSI report. ■ The UE shall / can set at least one of the reported CRI or SSBRI and / or CSI-related information (e.g., L1-SINR) to be a certain or dummy value. The dummy value of the CRI or SSBRI may be obtained by potentially extending the bitwidth of the CRI or SSBRI. The setting of certain or dummy value can be per beam, per time instance, or per CSI report, for the invalidity indication of the corresponding CSI information. ■ The UE shall / can set at least two of the reported CRI or SSBRI and / or CSI-related information (e.g., L1-SINR) to be the same value. The setting of two same values can be per time instance or per CSI report.
[0036] The benefit of CSI-related information (e.g., SINR, RSRP, or CQI) prediction may include, for example, reducing the RS resource transmission / measurement overhead, and power consumption at the UE side for the measurement of RS resource and acquirement of CSI-related information, since some CSI-related information can be predicted directly by the AI / ML model or functionality at the UE side, alleviating / mitigating the RS resource transmission and measurement overhead.
[0037] For example, in legacy, to obtain the SINR quality, 16 RS resources (or resource pairs) need to the transmitted by the NW and measured by the UE. With AI / ML model at the UE side, only 4 RS resources (or resource pairs, corresponding to the first set of one or more resource settings) need to the transmitted by the NW and measured by the UE. The measurement results of the 4 RS resources (or resource pairs) are used as model input, and the model output would be predicted SINR quality of all 16 RS resources (or resource pairs, corresponding to the second set of one or more resource settings) . Each resource pair includes one resource for channel measurement and one resource for interference.
[0038] AI or ML (Artificial Intelligence or Machine Learning) is a promising enhancement direction for mobile communication system, e.g., 5G (The fifth generation) , 5G-A (5G-Advanced) and 6G (The sixth generation) . With the introduction of AI or ML technology into the mobile communication system, the system operating efficiency is expected to be improved, e.g., reduce the overhead of reference signal via AI or ML inference and prediction. For example, AI or ML model-based beam prediction can directly predict the optimal narrow beam using measured results from an inference beam set that comprises wide beams or partial narrow beams. This approach significantly reduces the RS resource overhead required for exhaustive beam sweeping.
[0039] In some implementations, the UE is configured with at least one resource settings for channel measurement and at least one reporting settings for CSI report. Each reporting setting contains the parameters for one CSI reporting band and the CSI related quantities to be reported by the UE. For beam management, the CSI related quantities to be reported by the UE is indicated by the higher layer parameter reportQuantity in the reporting setting and mainly include CSI-RS resource indicator (CRI) , SS or PBCH Block Resource indicator (SSBRI) , L1-RSRP or L1-SINR. More specifically, the higher layer parameter reportQuantity can be set to ‘cri-RSRP’ , ‘cri-SINR’ , ‘ssb-Index-RSRP’ , and / or ‘ssb-Index-SINR’ . For example, if the higher layer parameter reportQuantity is set to ‘cri-RSRP’ , the UE shall / can report one or multiple CRI and associated L1-RSRP in a single report for each report setting, where the number of RS resources to be reported may be configured by the higher layer.
[0040] For L1-SINR reporting, if the number of RS resources to be reported per report setting is configured to be one, the reported L1-SINR value can be defined by a 7-bit value in the range [-23, 40] dB with 0.5 dB step size. If the number of measured RS resources to be reported per report setting is configured to be larger than one, the UE shall / can use differential L1-SINR based reporting, where the largest measured value of L1-SINR can be quantized to a 7-bit value in the range [-23, 40] dB with 0.5 dB step size, and the differential L1-SINR may be quantized to a 4-bit value. The differential L1-SINR value can be computed with 1 dB step size with a reference to the largest measured L1-SINR value which is part of the same L1-SINR reporting instance.
[0041] For L1-RSRP reporting, if the number of RS resources to be reported per report setting is configured to be one, the reported L1-RSRP value is defined by a 7-bit value in the range [-140, -44] dBm with 1dB step size. If the number of measured RS resources to be reported per report setting is configured to be larger than one, the UE shall use differential L1-RSRP based reporting, where the largest measured value of L1-RSRP is quantized to a 7-bit value in the range [-140, -44] dBm with 1dB step size, and the differential L1-RSRP is quantized to a 4-bit value. The differential L1-RSRP value is computed with 2 dB step size with a reference to the largest measured L1-RSRP value which is part of the same L1-RSRP reporting instance.

Furthermore, in this patent document, “beam state” may also be called as “beam” .

[0070] Implementation Example #1: CSI resource configuration for SINR prediction
[0071] For RS and / or SINR prediction or predicted quantity reporting at the UE side, the UE is provided a CSI reporting setting, where the CSI reporting setting is linked with a first one or multiple resource settings for channel measurement and / or for interference measurement, and a second one or multiple resource settings for predicted quantity reporting. The number of resources of the first one or multiple resource settings is lower or not greater than that of the second one or multiple resource settings.
[0072] FIG. 3 illustrates a configuration of the CSI resource setting in accordance with an embodiment of the disclosure. The first one or multiple resource settings for channel measurement and / or for interference measurement may include at least one of the followings. ● The first one or multiple resource settings include one resource setting for channel measurement on channel measurement resources. In some examples, the channel measurement resources may be SSB or NZP CSI-RS. ● The first one or multiple resource settings can include one resource setting for interference measurement. In some examples, the interference measurement resources may be CSI-IM or 1 port NZP CSI-RS with density 3 REs or RB. ● The first one or multiple resource settings can include one resource setting for channel and interference measurement on measurement resources. In some examples, the measurement resources may be 1 port NZP CSI-RS with density 3 REs or RB. ● The first one or multiple resource settings can include a first one resource setting for channel measurement on channel measurement resources and a second one resource setting for interference measurement on interference measurement resources. In some examples, the channel measurement resources may be SSB or NZP CSI-RS, or the interference measurement resources may be CSI-IM or 1 port NZP CSI-RS with density 3 REs or RB. Each channel measurement resource is associated with one interference measurement resource by the ordering of the channel measurement resource and interference measurement resource in the corresponding resource sets. The number of channel measurement resource equals to the number of interference measurement resource. ● The first one or multiple resource settings include a first one resource setting for channel measurement on channel measurement resources, a second resource setting for interference measurement on interference measurement resources, and a third resource setting for interference measurement on interference measurement resources. Typically, the second resource setting and the third resource setting are used for the measurement of intra-cell interference and inter-cell interference, respectively. In some examples, the channel measurement resources or the interference measurement resources may be SSB, NZP CSI-RS, or CSI-IM. In some examples, the channel measurement resources may be SSB or NZP CSI-RS, or the interference measurement resources associated with the second resource setting may be CSI-IM, or the interference measurement resources associated with the third resource setting may be 1 port NZP CSI-RS with density 3 REs or RB. Consider at least one of the followings for the one-to-one mapping between the channel measurement resource and the interference measurement resource. ■ Each channel measurement resource can be resource-wise associated with one interference measurement resource associated with the second resource setting by the ordering of the channel measurement resource and interference measurement resource in the corresponding resource sets. The number of channel measurement resource equals to the number of interference measurement resource associated with the second resource setting. ■ Each channel measurement resource can be resource-wise associated with one interference measurement resource associated with the third resource setting by the ordering of the channel measurement resource and interference measurement resource in the corresponding resource sets. The number of channel measurement resource may equal to the number of interference measurement resource associated with the third resource setting. ■ Each interference measurement resource associated with the second resource setting can be resource- wise associated with one interference measurement resource associated with the third resource setting by the ordering of the interference measurement resource in the corresponding resource sets. The number of interference measurement resource associated with the second resource setting can equal to the number of interference measurement resource associated with the third resource setting.
[0073] The UE can be provided (e.g., by a BS or TRP) with indication of the spatial Rx parameter (or quasi co-location relation) for the measurement of the channel measurement resource and / or interference measurement resource. If the first one or multiple resource settings include at least a first one resource setting for channel measurement and a second one resource setting for interference measurement, the UE may assume at least one of the followings. ● In some examples, the UE may assume that the channel measurement resource (e.g., NZP CSI-RS resource) and the interference measurement resource (e.g., CSI-IM resource or NZP CSI-RS resource) configured for one CSI reporting are QCLed with respect to ‘typeD’ . This is to indicate that a same spatial Rx parameter should be used by the UE for the measurement of the channel measurement resource and the interference measurement resource. ● In some examples, UE may apply the channel measurement resource, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the channel measurement resource, as the RS for determining ‘typeD’ assumption for the corresponding interference measurement resource configured for one CSI reporting. In some examples, UE may apply the SSB, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the NZP CSI-RS resource for channel measurement, as the RS for determining ‘typeD’ assumption for the corresponding CSI-IM resource or the corresponding NZP CSI-RS resource for interference measurement configured for one CSI reporting. ● UE may expect / determine that the channel measurement resource set and the interference measurement resource set, if any, are configured with the higher layer parameter repetition. In some examples, UE may expect that the NZP CSI-RS resource set for channel measurement and the NZP-CSI-RS resource set for interference measurement, if any, are configured with the higher layer parameter repetition. Wherein, if the higher layer parameter repetition is set to off or is absent, the UE may not assume that the RS resources within the resource set are transmitted with the same downlink spatial domain transmission filter. If the higher layer parameter repetition is set to on, the UE may assume that the RS resources within the resource set are transmitted with the same downlink spatial domain transmission filter.
[0074] A second one or multiple resource settings for predicted quantity reporting may include at least one of the following. The UE may not be expected to measure the resources in the second one or multiple resource settings. In other word, the second one or multiple resource settings are configured only for reporting purpose, and the network (or base station) may not transmit the resources in the second one or multiple resource settings. ● The second one or multiple resource settings can include one resource setting for predicted quantity reporting. In some examples, the resource associated with the second one or multiple resource settings may be SSB, CSI-IM, or NZP CSI-RS. ● The second one or multiple resource settings can include two resource settings for predicted quantity reporting, e.g., a first and a second resource settings. In some examples, the resource associated with the second one or multiple resource settings may be SSB, CSI-IM, or NZP CSI-RS. Each resource of the first resource setting can be associated with one resource of the second resource setting by the ordering of the resource in the corresponding resource sets. The number of resource of the first resource setting can be equal to the number of resource of the second resource setting. Similar as above, the UE may assume that the resource in the first resource setting and the resource in the second resource setting configured for one CSI reporting are QCLed with respect to ‘typeD’ . In some examples, UE may apply the resource in the first resource setting, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the resource in the first resource setting, as the RS for determining ‘typeD’ assumption for the corresponding resource in the second resource setting configured for one CSI reporting. In some examples, UE may expect / determine that the resource set of the first resource setting and the resource set of the second resource setting, if any, are configured with the higher layer parameter repetition. In some examples, UE may expect that the NZP CSI-RS resource set for channel measurement and the NZP-CSI-RS resource set for interference measurement, if any, are configured with the higher layer parameter repetition. ● The second one or multiple resource settings can include one resource setting for channel measurement. ● The second one or multiple resource settings can include one resource setting for channel measurement. ● The second one or multiple resource settings can include one resource setting for channel and interference measurement.
[0075] Implementation Example #2: CSI reporting configuration for SINR prediction
[0076] For RS and / or SINR prediction or predicted quantity reporting, the report quantity can be configured to be at least one of: predicted CRI or SSBRI, predicted CSI-related information (e.g., predicted L1-SINR) . Wherein, predicted CRI or SSBRI k (k≥0) corresponds to the configured (k+1) -th entry of associated resources in the corresponding resource set of the second (or first) one or multiple resource setting, and / or corresponds to the configured (k+1) -th entry of associated resources in the corresponding resource set for channel measurement of the second (or first) one or multiple resource setting, and / or corresponds to the configured (k+1) -th entry of associated resources in the corresponding resource set for interference measurement of the second (or first) one or multiple resource setting, and / or corresponds to the configured (k+1) -th entry of associated resources in the corresponding resource set for channel and interference measurement of the second (or first) one or multiple resource setting. ● In some examples, for each report setting for spatial-domain prediction (e.g., a number of future time instances N is not configured) , the UE shall / can report in a single report K different CRIs or SSBRIs of the second one or multiple resource settings, with or without corresponding predicted CSI-related information. ● In some examples, for each report setting for temporal prediction (e.g., a number of future time instances N is configured) , the UE shall / may report in a single report K different CRIs or SSBRIs of the second one or multiple resource settings for each of N time instances, with or without corresponding predicted CSI-related information. ● K≥1 is configured by the network (NW) , indicating the number of RS to be predicted and / or reported in a single report. N≥1 is configured by the NW, indicating the number of future time instances to be predicted and / or reported by the UE in a single report.
[0077] The UE shall / can determine the reported predicted CRI, predicted SSBRI, and / or predicted CSI-related information (e.g., predicted L1-SINR) based on: ● measurements (e.g., L1-SINR measurement) performed by the UE for the configured measurement resources associated with the first one or multiple resource settings, wherein, the configured measurement resources may be SSB, CSI-IM, and / or CSI-RS resources. ● prediction performed by the UE based on the measurements associated with the first one or multiple resource settings, for the configured prediction resources associated with the second one or multiple resource settings, wherein, the configured prediction resources may be SSB, CSI-IM, and / or CSI-RS resources.
[0078] Implementation Example #3: Associated ID configuration
[0079] The UE may be configured with one or two associated ID (s) . The associated ID can be configured for consistency across training and inference. ● If two associated IDs are configured, they are associated with the resource set of the first one or multiple resource settings and of the second one or multiple resource settings, respectively. ● If only one associated ID is configured, it can be associated with the resource sets of the second one or multiple resource settings. ■ In some examples, the UE can expect that all RS for determining QCL assumption for the corresponding resources in the resource set for channel and / or interference measurement of the first one or multiple resource settings are among or mapped to RS for determining QCL assumption for the corresponding resources in the resource set for channel and / or interference measurement (or predicted quantity reporting) of the second one or multiple resource settings. In other word, the RSs for determining QCL assumption for the corresponding resources in the first one or multiple resource settings can be a subset of that for the second one or multiple resource settings. In some examples, the UE can expect / determine that all RS for determining QCL assumption for the corresponding resources in the resource set of the first one or multiple resource settings are among or mapped to RS for determining QCL assumption for the corresponding resources in the resource set of the second one or multiple resource settings. ■ In some examples, UE may apply the resource of the second one or multiple resource settings, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the resource of the second one or multiple resource settings, as the RS for determining ‘typeD’ assumption for the corresponding resource of the first one or multiple resource settings configured for one CSI reporting. In some examples, UE may apply the resource of the first one or multiple resource settings, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the resource of the first one or multiple resource settings, as the RS for determining ‘typeD’ assumption for the corresponding resource of the second one or multiple resource settings configured for one CSI reporting. ■ In some examples, the UE can expect that all RS for determining ‘typeD’ assumption for the corresponding resources in the resource set of the first one or multiple resource settings are among or mapped to RS for determining ‘typeD’ assumption for the corresponding resources in the resource set of the second one or multiple resource settings. In other word, the RSs for determining ‘typeD’ assumption for the corresponding resources in the first one or multiple resource settings are a subset of that for the second one or multiple resource settings. ■ In some examples, the UE can expect that all resources in the resource set for channel and / or interference measurement associated with the first one or multiple resource setting are among or mapped to the resources in the resource set for channel and / or interference measurement (or predicted quantity reporting) associated with the second one or multiple resource setting. If a first resource is mapped to a second resource, it can mean that the two resources are QCLed with respect to ‘typeD’ or share the same RS for determining ‘typeD’ assumption. ■ In some examples, the UE can expect that all resources in the resource set of the first one or multiple resource setting are among or mapped to the resources in the resource set of the second one or multiple resource setting. ■ In some examples, the UE can expect that all resources in the resource set for channel measurement associated with the first one or multiple resource setting are among or mapped to the resources in the resource set for channel measurement (or predicted quantity reporting) associated with the second one or multiple resource setting. ■ In some examples, the UE can expect that all resources in the resource set for interference measurement associated with the first one or multiple resource setting are among or mapped to the resources in the resource set for interference measurement (or predicted quantity reporting) associated with the second one or multiple resource setting. ■ In some examples, the UE can expect that all resources in the resource set for channel and interference measurement associated with the first one or multiple resource setting are among or mapped to the resources in the resource set for channel and interference measurement (or predicted quantity reporting) associated with the second one or multiple resource setting.
[0080] If the same associated ID is configured to be associated with different resources or resource sets, the UE may assume similar or same properties (or downlink spatial Tx filter) for the resources among those different resource sets, or the UE may use similar or same spatial Rx parameter for measurement on the resources among those different resource sets, irrespective of when the corresponding resource setting (s) is configured by higher layer signalling or released.
[0081] Implementation Example #4: CSI reporting configuration for monitoring
[0082] For monitoring purpose, the UE may be configured with a first CSI reporting setting for reporting predicted CRI or SSBRI and / or predicted CSI-related information (i.e., the CSI reporting configuration for inference mentioned in implementation #2, named as inference reporting setting) , and a second CSI reporting setting for reporting prediction accuracy (named as monitoring reporting setting) .
[0083] FIG. 4 illustrates a linkage between inference reporting setting and monitoring reporting setting, in accordance with some embodiments of the present disclosure. The monitoring reporting setting is linked to the inference reporting setting by configuring the inference reporting setting ID in the monitoring reporting setting. The reporting of prediction accuracy corresponding to the monitoring reporting setting may follow the following procedures. For each of the T latest transmission occasion (s) , where the latest transmission occasion of T latest transmission occasion (s) , and / or the latest report of the inference reporting setting considered for linking, are no later than the CSI reference resource corresponding to the CSI report of the monitoring reporting setting, the UE shall consider at least one of the following. ● The UE may be provided with one monitoring resource set for channel and interference measurement. Or, the UE may be provided with one monitoring resource set for channel measurement and another monitoring resource set for interference measurement, and the monitoring resource (s) for channel measurement and the monitoring resource (s) for interference measurement configured for the monitoring reporting are resource-wise QCLed with respect to ‘typeD’ . ● The UE shall / can perform measurements (e.g., L1-SINR measurements) for the configured resources, associated with the transmission occasion of the corresponding monitoring resource set for channel and / or interference measurement of the monitoring reporting setting. ● The UE shall / can determine the best M resources based on measurements (e.g., L1-SINR measurements) of the corresponding monitoring resource set associated with the monitoring reporting setting. ● The UE shall / may check a condition: at least one of the M identified resources is mapped to one of the K reported predicted CRI or SSBRI of the linked report of the inference reporting setting. If this condition and potential some other conditions are met, the transmission occasion is counted as an accurate prediction instance; otherwise, it is not counted as an accurate prediction instance. ● The UE shall / may determine prediction accuracy as the total count of accurate prediction instances T1, or the total count of inaccurate prediction instances T2, or the ratio between the total count of accurate (or inaccurate) prediction instances and T (i.e., T1 or T or T2 or T) , or the ratio between the total count of accurate (or inaccurate) prediction instances and the sum of the total count of accurate and inaccurate prediction instances (i.e., T1 or (T1+T2) or T2 or (T1+T2) ) . ● Wherein, M is equal to a certain value (e.g., 1, or 2) or is configured by the NW. T is configured by the NW.
[0084] Wherein, the mapping between resources of the monitoring resource set for channel and / or interference measurement of the monitoring reporting setting and resources of the second one or multiple resource settings (named as prediction resource set) of the inference reporting setting may be indicated to the UE.
[0085] In some cases, the number of resources of the monitoring resource set for channel and / or interference measurement (or the resource setting associated with the monitoring reporting setting) can be the same as that of the prediction resource set (e.g., the resource set of the second one or multiple resource setting associated with the inference reporting setting) . In this case, the n-th resource in the monitoring resource set for channel and / or interference measurement is mapped to the n-th resource in that of the prediction resource set. Each monitoring resource of the monitoring resource set for channel and / or interference measurement may be resource-wise associated or mapped with one prediction resource in the prediction resource set by the ordering of the monitoring resource and prediction resource in the corresponding resource sets. ● In some examples, the UE may assume that the monitoring resource and the prediction resource are QCLed with respect to ‘typeD’ . ● In some examples, UE may apply the monitoring resource, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the monitoring resource, as the RS for determining ‘typeD’ assumption for the corresponding prediction resource. ● In some examples, UE may apply the prediction resource, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the prediction resource, as the RS for determining ‘typeD’ assumption for the corresponding monitoring resource.
[0086] In some cases, the number of resources of the monitoring resource set for channel and / or interference measurement (or the resource setting associated with the monitoring reporting setting) is smaller than that of the prediction resource set (e.g., the resource set of the second one or multiple resource setting associated with the inference reporting setting) . In this case, the mapping between the monitoring resource set for channel and / or interference measurement and the prediction resource set is indicated to the UE by a bitmap. In some examples, a X-bit bitmap with Y non-zero bits is configured to the UE (e.g., in the monitoring reporting setting) , where X is the size of prediction resource set and Y is the size of the monitoring resource set for channel and / or interference measurement. The x-th MSB (or LSB) of the bitmap corresponds to x-th resource in the prediction resource set. The y-th nonzero bit of the bitmap corresponds to or is associated or mapped with the y-th entry of associated monitoring resource set, 1≤y≤Y. ● In some examples, the UE may assume that the monitoring resource and the associated or mapped prediction resource are QCLed with respect to ‘typeD’ . ● In some examples, UE may apply the monitoring resource, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the monitoring resource, as the RS for determining ‘typeD’ assumption for the corresponding associated or mapped prediction resource. ● In some examples, UE may apply the prediction resource, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the prediction resource, as the RS for determining ‘typeD’ assumption for the corresponding associated or mapped monitoring resource.
[0087] Implementation Example #5: Invalidity indication in UE reporting
[0088] Limited by the model generalization and dynamic UE-side additional conditions (e.g., UE speed, UE rotation, UE dropping) , the model deployed at the UE side may not work well all the time and invalid CSI information may be generated and / or reported by the UE. Note that the CSI information may include CRI or SSBRI and / or CSI-related information (e.g., L1-RSRP, L1-SINR) . To avoid any wrong interpretation at the NW side, the UE shall indicated in the UE reporting whether the reported CSI information is invalid, implying that those reported CSI information may not be considered for the subsequent NW scheduling. Here, the term ‘invalid’ is used intended to be interpreted in the inclusive sense, unless otherwise explicitly indicated. For example, ‘invalid’ can refer to inaccurate, untrustworthy, unreliable, undependable, wrong, incorrect, failure.
[0089] For the indication of invalidity, the UE reporting shall / can follow at least one of the following rules.

[0091] The UE shall / can report performance indicator to indicate whether the corresponding CSI information is valid or not. If the performance indicator is set to a first value (e.g., 1) , it may indicate that the corresponding CSI information is valid. Otherwise, if the performance indicator is set to a second value (e.g., 0) , it can indicate that the corresponding CSI information is invalid. ● The performance indicator can be reported per CRI, SSBRI, resource, beam, or CSI-related information. Each reported CRI, SSBRI, resource, beam, CSI-related information is associated with a performance indicator. By setting the performance indicator to different values, the validity of the corresponding CRI, SSBRI, resource, beam, CSI-related information can be indicated to the NW. ● The performance indicator can be reported per time instance. For each report setting for temporal prediction, a number of future time instances N is configured to the UE. Reported CSI information of each time instance is associated with a performance indicator. By setting the performance indicator to different values, the validity of the CSI information of the corresponding time instance can be indicated to the NW. ● The performance indicator can be reported per reporting instance. The performance indicator may be reported in each single report. In other word, all reported CSI information of each reporting instance is associated with a performance indicator. By setting the performance indicator to different values, the validity of the CSI information of the corresponding reporting instance can be indicated to the NW.
[0092] Method#2: Reporting of certain or dummy value for the CRI or SSBRI and / or CSI-related information
[0093] The UE shall / can set at least one of the reported CRI or SSBRI to be a certain or dummy value. By setting at least one reported CRI or SSBRI to a certain or dummy value, or by setting all reported CRIs or SSBRIs to a certain or dummy value, the UE indicates that the corresponding reported CSI information is invalid. ● In some examples, e.g., in legacy design, the predicted CRI or SSBRI k (k≥0 and k≤M-1) corresponds to the configured (k+1) -th entry of associated resources in the corresponding resource set of the second one or multiple resource setting. The bitwidth of the predicted CRI or SSBRI is where M is the number of resources in the corresponding resource set of the second one or multiple resource setting. ● In some examples, the predicted CRI or SSBRI k (k≥0 and k≤M-1) can correspond to the configured (k+1) -th entry of associated resources in the corresponding resource set of the second one or multiple resource setting, and predicted CRI or SSBRI k=M corresponds to an additional dummy value (i.e., no corresponding resource) . The bitwidth of the predicted CRI or SSBRI is where M is the number of resources in the corresponding resource set of the second one or multiple resource setting. ● In some examples, the predicted CRI or SSBRI k (k≥1 and k≤M) corresponds to the configured k-th entry of associated resources in the corresponding resource set of the second one or multiple resource setting, and predicted CRI or SSBRI k=0 corresponds to an additional dummy value. The bitwidth of the predicted CRI or SSBRI is where M is the number of resources in the corresponding resource set of the second one or multiple resource setting. ● The invalidity may be indicated to the NW per CSI report. In some examples, by setting at least one reported CRI or SSBRI of a single CSI report to a certain value (e.g., 0, 1, M-1, or the dummy value mentioned above) , or by setting all reported CRIs or SSBRIs of a single CSI report to a certain value (e.g., 0, 1, M-1) , the UE can indicate that the all reported CSI information in the single report is invalid. ● The invalidity may be indicated to the NW per CRI or SSBRI or resource or beam or CSI-related information. In some examples, by setting a reported CRI or SSBRI to a certain value (e.g., 0, 1, M-1, or the dummy value mentioned above) , the UE can indicate that the reported CSI information corresponding to the CRI or SSBRI is invalid. Specifically, a single report may include one or multiply CSI information corresponding to different CRIs or SSBRIs or resources or beams or CSI-related information. For the indication of validity of each CSI information, the UE may not report the corresponding CRI or SSBRI to be the certain or dummy value. For the indication of invalidity of each CSI information, the UE may report the corresponding CRI or SSBRI to be the certain or dummy value. An example US reporting is shown in Table 1. Table 1: An example UE reporting
[0094] The invalidity may be indicated to the NW per time instance. In some examples, e.g., for each report setting for temporal prediction, a number of future time instances N is configured to the UE. The UE shall / may report in a single report K (higher layer configured) CRI or SSBRI for each of the N future time instances for each report setting. For the indication of validity, the UE may not report any CRI or SSBRI to be the certain or dummy value. For the indication of invalidity of a single CSI report, the UE may report at least one CRI or SSBRI to be the certain or dummy value. Or, for the indication of invalidity of CSI information associated with a time instance, the UE may report at least one CRI or SSBRI corresponding to the time instance to be the certain or dummy value. An example US reporting is shown in Table 2. Table 2: An example UE reporting
[0095] In some examples, there are at least two dummy values for the CRI or SSBRI and / or CSI-related information. The UE shall / can set at least one of the reported CRI or SSBRI to be a certain or dummy value. By setting at least one reported CRI or SSBRI to a first certain or dummy value, or by setting all reported CRIs or SSBRIs to a first certain or dummy value, the UE can indicate that the corresponding reported CSI information is invalid. Otherwise, by setting at least one reported CRI or SSBRI to a second certain or dummy value, or by setting all reported CRIs or SSBRIs to a second certain or dummy value, the UE can indicate that the corresponding reported CSI information is valid. ● In some examples, the predicted CRI or SSBRI k (k≥0 and k≤M-1) corresponds to the configured (k+1) -th entry of associated resources in the corresponding resource set of the second one or multiple resource setting, and predicted CRI or SSBRI k=M and K=M+1 corresponds to two additional dummy values. The bitwidth of the predicted CRI or SSBRI can be where M is the number of resources in the corresponding resource set of the second one or multiple resource setting. ● In some examples, by setting at least one reported CRI or SSBRI to a first certain or dummy value (e.g., k=M) , or by setting all reported CRIs or SSBRIs to a first certain or dummy value, the UE can indicate that all reported CSI information in a single report (or the corresponding CSI information or the corresponding CSI information of the same time instance) is invalid. By setting at least one reported CRI or SSBRI to a second certain or dummy value (e.g., k=M+1) , or by setting all reported CRIs or SSBRIs to a second certain or dummy value, the UE can indicate that all reported CSI information (or the corresponding CSI information or the corresponding CSI information of the same time instance) in a single report is valid.
[0096] In some examples, the UE shall / can set at least one of the reported CSI-related information (or {CRI or SSBRI, CSI-related information} pair) to be a certain or dummy value, e.g., CRI or SSBRI=X, and / or CSI-related information=Y. By setting at least one reported CSI-related information (or {CRI or SSBRI, CSI-related information} pair) to a certain or dummy value, or by setting all reported CSI-related information (or {CRI or SSBRI, CSI-related information} pair) to a certain or dummy value, the UE can indicate that the corresponding reported CSI information is invalid. The certain or dummy value is configured by the NW, or pre-known by the NW and UE. Here, {CRI or SSBRI, CSI-related information} pair represents a CRI or SSBRI and associated CSI-related information. ● The invalidity may be indicated to the NW per CSI report. In some examples, by setting at least one reported CSI-related information (or {CRI or SSBRI, CSI-related information} pair) of a single CSI report to a certain value, or by setting all reported CSI-related information (or {CRI or SSBRI, CSI-related information} pair) of a single CSI report to a certain value, the UE can indicate that the all reported CSI information in the single report is invalid. ● The invalidity may be indicated to the NW per CRI or SSBRI or resource or beam or CSI-related information. In some examples, by setting a reported CSI-related information (or {CRI or SSBRI, CSI-related information} pair) to a certain value, the UE can indicate that the reported CSI information corresponding to the CSI-related information (or {CRI or SSBRI, CSI-related information} pair) is invalid. Specifically, a single report may include one or multiply CSI information corresponding to different CRIs or SSBRIs or resources or beams or CSI-related information. For the indication of validity of each CSI information, the UE may not report the corresponding CSI-related information (or {CRI or SSBRI, CSI-related information} pair) to be the certain or dummy value. For the indication of invalidity of each CSI information, the UE may report the corresponding CSI-related information (or {CRI or SSBRI, CSI-related information} pair) to be the certain or dummy value. ● The invalidity may be indicated to the NW per time instance. In some examples, e.g., for each report setting for temporal prediction, a number of future time instances N is configured to the UE. The UE shall report in a single report K (higher layer configured) CSI-related information (or {CRI or SSBRI, CSI-related information} pair) for each of the N future time instances for each report setting. For the indication of invalidity of CSI information associated with a time instance, the UE may report at least one CSI-related information (or {CRI or SSBRI, CSI-related information} pair) corresponding to the time instance to be the certain or dummy value.
[0097] Method#3: Reporting of duplicate CRI or SSBRI values
[0098] For the indication of invalidity, the UE shall set at least two of the reported CRI or SSBRI to be the same value. Specifically, at least two of the reported CRI or SSBRI (of the CSI report or of a same time instance associated with the CSI report) are the same, or all reported CRI or SSBRI (of the CSI report or of a same time instance associated with the CSI report) are the same. Apparently, this case is conditioned on K>1. ● In some examples, e.g., for each report setting for spatial domain prediction, a number of future time instances N is not configured to the UE. The UE shall report in a single report K (higher layer configured) CRI or SSBRI for each report setting. For the indication of validity, the UE shall report K different CRI or SSBRI for each report setting. For the indication of invalidity, the UE shall report K CRI or SSBRI for each report setting, wherein, at least two of the reported CRI or SSBRI are the same, or all reported CRI or SSBRI are the same. ● In some examples, e.g., for each report setting for temporal prediction, a number of future time instances N is configured to the UE. The UE shall report in a single report K (higher layer configured) CRI or SSBRI for each of the N future time instances for each report setting. For the indication of validity, the UE shall report K different CRI or SSBRI for each of the N future time instances for each report setting. For the indication of invalidity of a single CSI report (or reported CSI information associated with the single CSI report, or a time instance of the CSI report, or reported CSI information associated with a time instance of the CSI report) , at least two of the reported CRI or SSBRI corresponding to a same time instance are the same, or all reported CRI or SSBRI corresponding to a same time instance are the same. Or, for the indication of invalidity of reported CSI information of a time instance, the UE shall report K CRI or SSBRI for each of the N future time instances for each report setting, wherein, at least two of the reported CRI or SSBRI corresponding to the time instance are the same, or all reported CRI or SSBRI corresponding to the time instance are the same. An example US reporting is shown in Table 3. Table 3: An example UE reporting
[0099] Method#4: Reporting based on threshold for the CRI or SSBRI and / or CSI-related information
[0100] In some examples, the UE can indicate invalidity by only reporting CSI-related information (and / or CRI or SSBRI) lower or not greater than a pre-defined threshold. In some examples, the UE can indicate invalidity by only reporting CSI-related information (and / or CRI or SSBRI) larger or not lower than a pre-defined threshold. Assume that the CSI-related information is L1-RSRP, and the reporting quantity is configured to be CRI or SSBRI and L1-RSRP. For the indication of invalidity, the UE shall report K (higher layer configured) CRI or SSBRI and / or corresponding L1-RSRP for each report setting, wherein, a number of (e.g., K) reported L1-RSRP are lower or not greater than a pre-defined threshold. The threshold may be configured by the NW. Since all or a number of reported CSI-related information (e.g., L1-RSRP) are with low strength or quality, the NW can understand that the reported CSI is unreliable.
[0101] Method#5: Reporting only based on measurements
[0102] As mentioned above, the UE shall / can perform prediction for the configured prediction resources associated with the second one or multiple resource settings, based on the measurements associated with the first one or multiple resource settings. If the prediction at the UE side is not reliable, the UE shall / can perform CSI reporting only based on the measurements associated with the first one or multiple resource settings. Specifically, if all or partial or at least one resources in the resource set of the first one or multiple resource setting are among the resources in the resource set of the second one or multiple resource setting, for the indication of invalidity, all reported CRI or SSBRI shall / may corresponds to resources in the corresponding resource set of the first one or multiple resource setting. The CSI reporting content can be derived based on the measurements associated with the first one or multiple resource settings. For example, resources of the first one or multiple resource settings include resource#1, resource#3, and resources of the second one or multiple resource settings include resource#1, resource#2, resource#3, resource#4. Then, for the indication of invalidity, the UE shall or would only report CRI#0 and / or CRI#2, which correspond to the 1st and 2nd resources in the first one or multiple resource settings.
[0103] Implementation Example #6: CSI reporting configuration for data collection
[0104] For data collection at the UE side, the UE may be provided a CSI reporting setting, where the CSI reporting setting is linked with a first one or multiple resource settings for channel measurement and / or for interference measurement, and a second one or multiple resource settings for channel measurement and / or for interference measurement. The reporting quantity is configured to be none. In other word, there is no CSI report for the CSI reporting setting for data collection, or the UE shall not or is not expect to report any quantity for the CSI reporting setting for data collection.
[0105] The first one or multiple resource settings for channel measurement and / or for interference measurement (and / or the second one or multiple resource settings for channel measurement and / or for interference measurement) may include at least one of the followings. ● The number of resources of the first one or multiple resource settings is lower or not greater than that of the second one or multiple resource settings. ● The first or second one or multiple resource settings can include one resource setting for channel measurement on channel measurement resources. In some examples, the channel measurement resources may be SSB or NZP CSI-RS. ● The first or second one or multiple resource settings can include one resource setting for interference measurement. In some examples, the interference measurement resources may be CSI-IM or 1 port NZP CSI-RS with density 3 REs or RB. ● The first or second one or multiple resource settings can include one resource setting for channel and interference measurement on measurement resources. In some examples, the measurement resources may be 1 port NZP CSI-RS with density 3 REs or RB. ● The first or second one or multiple resource settings can include a first one resource setting for channel measurement on channel measurement resources and a second one resource setting for interference measurement on interference measurement resources. In some examples, the channel measurement resources may be SSB or NZP CSI-RS, or the interference measurement resources may be CSI-IM or 1 port NZP CSI-RS with density 3 REs or RB. Each channel measurement resource may be associated with one interference measurement resource by the ordering of the channel measurement resource and interference measurement resource in the corresponding resource sets. The number of channel measurement resource can equal to the number of interference measurement resource. ● The first or second one or multiple resource settings can include a first one resource setting for channel measurement on channel measurement resources, a second resource setting for interference measurement on interference measurement resources, and a third resource setting for interference measurement on interference measurement resources. Typically, the second resource setting and the third resource setting are used for the measurement of intra-cell interference and inter-cell interference, respectively. In some examples, the channel measurement resources or the interference measurement resources may be SSB, NZP CSI-RS, or CSI-IM. In some examples, the channel measurement resources may be SSB or NZP CSI-RS, or the interference measurement resources associated with the second resource setting may be CSI-IM, or the interference measurement resources associated with the third resource setting may be 1 port NZP CSI-RS with density 3 REs or RB. Consider at least one of the following for the one-to-one mapping between the channel measurement resource and the interference measurement resource. ■ Each channel measurement resource can be resource-wise associated with one interference measurement resource associated with the second resource setting by the ordering of the channel measurement resource and interference measurement resource in the corresponding resource sets. The number of channel measurement resource equals to the number of interference measurement resource associated with the second resource setting. ■ Each channel measurement resource can be resource-wise associated with one interference measurement resource associated with the third resource setting by the ordering of the channel measurement resource and interference measurement resource in the corresponding resource sets. The number of channel measurement resource equals to the number of interference measurement resource associated with the third resource setting. ■ Each interference measurement resource associated with the second resource setting can be resource- wise associated with one interference measurement resource associated with the third resource setting by the ordering of the interference measurement resource in the corresponding resource sets. The number of interference measurement resource associated with the second resource setting equals to the number of interference measurement resource associated with the third resource setting.
[0106] The UE can be provided with indication of the spatial Rx parameter (or quasi co-location relation) for the measurement of the channel measurement resource and / or interference measurement resource. If the first or second one or multiple resource settings include at least a first one resource setting for channel measurement and a second one resource setting for interference measurement, the UE may assume at least one of the followings. ● In some examples, the UE may assume that the channel measurement resource (e.g., NZP CSI-RS resource) and the interference measurement resource (e.g., CSI-IM resource or NZP CSI-RS resource) configured for one CSI reporting are QCLed with respect to ‘typeD’ . This is to indicate that a same spatial Rx parameter should be used by the UE for the measurement of the channel measurement resource and the interference measurement resource. ● In some examples, UE may apply the channel measurement resource, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the channel measurement resource, as the RS for determining ‘typeD’ assumption for the corresponding interference measurement resource configured for one CSI reporting. In some examples, UE may apply the SSB, or ‘typeD’ RS configured with qcl-Type set to ‘typeD’ to the NZP CSI-RS resource for channel measurement, as the RS for determining ‘typeD’ assumption for the corresponding CSI-IM resource or the corresponding NZP CSI-RS resource for interference measurement configured for one CSI reporting. ● UE may expect that the channel measurement resource set and the interference measurement resource set, if any, are configured with the higher layer parameter repetition. In some examples, UE may expect that the NZP CSI-RS resource set for channel measurement and the NZP-CSI-RS resource set for interference measurement, if any, are configured with the higher layer parameter repetition. Wherein, if the higher layer parameter repetition is set to off or is absent, the UE may not assume that the RS resources within the resource set are transmitted with the same downlink spatial domain transmission filter. If the higher layer parameter repetition is set to on, the UE may assume that the RS resources within the resource set are transmitted with the same downlink spatial domain transmission filter.
[0107] It should be understood that one or more features from the above / following implementations / examples / embodiments are not exclusive to the specific implementations / examples / embodiments, but can be combined in any manner (e.g., in any priority and / or order, concurrently or otherwise) .
[0108] Referring now to FIG. 5, depicted is a flow diagram of a process 500 for prediction of CSI-related information (e.g., SINR, RSRP, or CQI) and invalidity indication. The process 500 may be implemented (e.g., performed) using any of the components described herein above, such as a wireless communication device (e.g., terminal, UE 104, 204) , or a wireless communication node (e.g., BS 102, 202) . In a brief overview, a wireless communication device may receive the CSI reporting setting from the wireless communication node (510) . The wireless communication device may transmit at least one predicted quantity based on the CSI reporting setting (515) . The wireless communication node may be a base station, such as BS 102, 202. The wireless communication device may be a user equipment, such as UE 104, 204. In some implementations, the CSI reporting setting is associated with a first set of one or more resource settings for at least one of channel measurement or interference measurement, and a second set of one or more resource settings for reporting the at least one predicted quantity or for at least one of channel measurement or interference measurement.
[0109] In further detail, the wireless communication node may transmit (e.g., send) to a wireless communication device, a channel state information (CSI) reporting setting (505) . The wireless communication node may receive from the wireless communication device at least one predicted quantity based on the CSI reporting setting (520) . The CSI reporting setting is associated with a first set of one or more resource settings for at least one of channel measurement or interference measurement and a second set of one or more resource settings for reporting the at least one predicted quantity or for at least one of channel measurement or interference measurement.
[0110] In some implementations, the first set of one or more resource settings comprises at least one of a resource setting for channel measurement; a resource setting for channel measurement and interference measurement; a first resource setting for channel measurement and a second resource setting for interference measurement; or a third resource setting for channel measurement, a fourth resource setting for interference measurement, and a fifth resource setting for interference measurement.
[0111] In some implementations, each channel measurement resource for the first resource setting for channel measurement is associated with an interference measurement resource for the second resource setting for interference measurement, according to an order of the channel measurement resource in a channel measurement resource set for the first resource setting for channel measurement and / or an order of the interference measurement resource in a interference measurement resource set for the second resource setting for interference measurement.
[0112] In some implementations, each channel measurement resource for the third resource setting for channel measurement is resource-wise associated with an interference measurement resource for the fourth resource setting for interference measurement, according to an order of the channel measurement resource in a channel measurement resource set for the third resource setting for channel measurement and / or an order of the interference measurement resource in an interference measurement resource set for the fourth resource setting for interference measurement. In some implementations, each channel measurement resource for the third resource setting for channel measurement is resource-wise associated with an interference measurement resource for the fifth resource setting for interference measurement, according to an order of the channel measurement resource in a channel measurement resource set for the third resource setting for channel measurement and / or an order of the interference measurement resource in an interference measurement resource set for the fifth resource setting for interference measurement. In some implementations, each interference measurement resource for the fourth resource setting for interference measurement is resource-wise associated with an interference measurement resource for the fifth resource setting for interference measurement, according to an order of the interference measurement resource in an interference measurement resource set for the fourth resource setting for interference measurement and / or an order of the interference measurement resource in an interference measurement resource set for the fifth resource setting for interference measurement.
[0113] In some implementations, a channel measurement resource for the first resource setting for channel measurement and an interference measurement resource for the second resource setting for interference measurement are quasi-co-located (QCLed) with respect to “typeD. ” In some implementations, a channel measurement resource for the third resource setting for channel measurement, an interference measurement resource for the fourth resource setting for interference measurement, and / or an interference measurement resource for the fifth resource setting for interference measurement are QCLed with respect to the “typeD. ” In some implementations, the wireless communication device is not expected or necessary to measure resources in the second set of one or more resource settings.
[0114] In some implementations, the second set of one or more resource settings comprises at least one of a resource setting for predicted quantity reporting, a first resource setting, or a second resource setting. In some implementations, each first resource from a first resource set associated with the first resource setting corresponds to a second resource from a second resource set associated with the second resource setting, according to an order of the first resource in the first resource set and an order of the second resource in the second resource set.
[0115] In some implementations, the first resource and the second resource are QCLed with respect to “typeD. ” In some implementations, the at least one predicted quantity comprises at least one of a predicted CSI-reference signal (CSI-RS) resource indicator (CRI) or synchronization signal block resource indicator (SSBRI) or a predicted CSI-related information. In some implementations, the predicted CRI or SSBRI, k, corresponds to a (k+1) -th entry of resources in a corresponding resource set associated with the first or second set of one or more resource settings, k being an integer no smaller than 0. In some implementations, the predicted CSI-related information comprises a predicted layer 1 signal to interference plus noise ratio (L1-SINR) or a predicted layer 1 reference signal received power (L1-RSRP) .
[0116] In some implementations, the at least one predicted quantity is determined based on at least one of: the at least one of channel measurement or interference measurement performed by the wireless communication device according to the first set of one or more resource settings, or predictions performed by the wireless communication device for configured resources associated with the second set of one or more resource settings. In some implementations, the wireless communication device is configured with one or more associated identifiers (IDs) . In some implementations, the wireless communication device is configured with a first associated ID and a second associated ID. In some implementations, the first associated ID is associated with a first resource set of the first set of one or more resource settings, and / or the second associated ID is associated with a second resource set of the second set of one or more resource settings.
[0117] In some implementations, the wireless communication device is configured with only one associated ID.In some implementations, the only one associated ID is associated with a resource set of the second set of one or more resource settings. In some implementations, all reference signals (RSs) for determining a QCL assumption for first resources in a resource set of the first set of one or more resource settings is same as, a subset of, among, or mapped to all RSs for determining the QCL assumption for second resources in the resource set of the second set of one or more resource settings. In some implementations, a resource set of the first set of one or more resource settings is same as, a subset of, among, or mapped to the resource set of the second set of one or more resource settings.
[0118] In some implementations, when different resource sets are associated with a same associated ID, at least one of resources from the different resource sets share same or substantially similar properties or a same or substantially similar downlink spatial transmitter (Tx) filter for resources or resource sets among those different resource sets; or a same or substantially similar spatial receiver (Rx) parameter is used by the wireless communication device for measurement on the resources from those different resource sets. In some implementations, the wireless communication device may transmit to the wireless communication node a performance indicator, e.g., a performance indicator that indicates whether the at least one predicted quantity is valid or at least partially invalid.
[0119] In some implementations, the wireless communication node may receive from the wireless communication device a performance indicator, e.g., a performance indicator that indicates whether the at least one predicted quantity is valid or at least partially invalid. In some implementations, the performance indicator is associated with at least one of: each of the at least one predicted quantity; at least a portion of the at least one predicted quantity corresponding to a same time instance or time interval associated with the CSI reporting setting; or the at least one predicted quantity. In some implementations, the at least one predicted quantity comprises a predicted CSI-reference signal (CSI-RS) resource indicator (CRI) or synchronization signal block resource indicator (SSBRI) , and wherein the predicted CRI or SSBRI is designated to be a value indicating that the at least one predicted quantity is invalid or at least partially invalid, or at least a portion of the at least one predicted quantity is invalid, or one of the at least one predicted quantity is invalid.
[0120] In some implementations, the one of the at least one predicted quantity comprises at least one of: a corresponding CRI, a corresponding SSBRI, and / or a corresponding predicted CSI-related information. In some implementations, the portion of the at least one predicted quantity corresponds to a same time instance or time interval associated with the CSI reporting setting. In some implementations, the value is the same as or greater than a number of resources in a resource set of the first or second set of one or more resource setting.
[0121] In some implementations, a bit-width of the predicted CRI or SSBRI is an integer that is equal to or no smaller than log2 (M+1) , M being the number of resources in the resource set of the first or second set of one or more resource setting. In some implementations, the at least one predicted quantity comprises a first predicted CSI-reference signal (CSI-RS) resource indicator (CRI) or synchronization signal block resource indicator (SSBRI) and a second CRI or SSBRI, and wherein the first CRI or SSBRI has a same value as the second CRI or SSBRI, indicating the at least one predicted quantity is invalid or at least partially invalid, or at least a portion of the at least one predicted quantity is invalid. In some implementations, the first CRI or SSBRI and the second CRI or SSBRI are invalid, or wherein the portion of the at least one predicted quantity corresponds to a same time instance or time interval associated with the CSI reporting setting.
