Description

Technical Field

[0001] This manual relates to wireless communication. Background Technology

[0002] A communication system can be a facility that enables communication between two or more nodes or devices (such as fixed or mobile communication devices). Signals can be carried on wired or wireless carrier waves.

[0003] Examples of cellular communication systems are based on the architecture standardized by the 3rd Generation Partnership Project (3GPP). The development of 5G New Radio (NR) is part of the ongoing evolution of mobile broadband to meet 5G requirements, similar to the early evolution of 3G and 4G wireless networks. Furthermore, in addition to mobile broadband, 5G targets emerging use cases. The goal of 5G is to deliver significant improvements in wireless performance, which can include new levels of data rates, latency, reliability, and security. 5G NR can also be extended to efficiently connect massive Internet of Things (IoT) and can provide new types of mission-critical services. For example, ultra-reliable and low-latency communication (URLLC) devices may require high reliability and very low latency. Additionally, non-terrestrial networks are being developed where signals between base stations (or gNBs) and UEs can be relayed via satellite.

[0004] Another example is 6G, which is designed to continue the shift of hosting network functions in cloud platforms. Deployment will move from dedicated telecom cloud platforms to general public, private, or hybrid clouds that can be located on-premises, at the (remote) edge, or at a central site. 6G will provide a unified orchestration interface for service management in distributed clouds, complemented by segment-specific abstractions, such as those for 6GRAN. Artificial intelligence and machine learning technologies are expected to be integral to the 6G architecture. They are the technologies needed to realize the vision of a truly cognitive network that adapts itself to a variety of scenarios and deployments. Summary of the Invention

[0021] It should be understood that although terms such as "first," "second," etc., preceding nouns may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another, and they do not restrict the order of the nouns. For example, without departing from the scope of the exemplary embodiments, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. As used herein, the term "and / or" includes any and all combinations of one or more of the listed terms.

[0022] As used herein, unless explicitly stated otherwise, the execution step “in response to A” does not indicate that the step is performed immediately after “A” occurs, and may include one or more intermediate steps.

[0023] Figure 1 This is a block diagram of wireless network 130. Figure 1 In the wireless network 130, user equipment 131, 132, 133, and 135 (which may also be referred to as mobile stations (MS) or user equipment (UE)) can connect to (and communicate with) base station 134, which may also be referred to as access point (AP), enhanced node B (eNB), gNB, or RAN (radio access network) node. BS (or AP) 134 provides radio coverage within cell 136, including providing radio coverage to user equipment (or UE) 131, 132, 133, and 135. BS 134 is also connected to core network 150 via N2 or NG interface 151. Although only four user equipment (or UE) are shown connected to or attached to one BS 134, any number of user equipment and / or BSs can be provided.

[0024] At least some of the functions of a BS (e.g., NG-RAN, gNB, Access Point (AP), Base Station (BS), or (e)Node B (eNB), RAN node) can also be performed by any node, server, or host that can be operatively coupled to a transceiver (such as a remote wireless head). For example, some functions of a BS can be performed at least partially in a central / centralized unit (CU) and / or distributed unit (DU). Therefore, a 5G network architecture can be based on a so-called CU-DU split. A gNB-CU (central node) can control multiple spatially separated gNB-DUs, at least acting as a transmit / receive (Tx / Rx) node. However, in some embodiments, a gNB-DU (also referred to as a DU) may include, for example, a Radio Link Control (RLC), Media Access Control (MAC) layer, and a Physical (PHY) layer, while a gNB-CU (also referred to as a CU) may include layers above the RLC layer, such as the Packet Data Convergence Protocol (PDCP) layer, Radio Resource Control (RRC), and Internet Protocol (IP) layer. Other functional splits are also possible.

[0025] According to the illustrative example, a radio access network (RAN) can be part of a mobile telecommunications system. The RAN can include one or more BSs or RAN nodes that implement radio access technologies, such as allowing one or more UEs to access the network or core network (CN). Thus, for example, the RAN (RAN nodes, such as BSs or gNBs) can reside between one or more user equipments or UEs and the core network. According to the example embodiment, each RAN node (e.g., BS, eNB, gNB, CU / DU…) or BS can provide one or more wireless communication services for one or more UEs or user equipments, such as allowing UEs to wirelessly access the network via the RAN node. Each RAN node or BS can perform or provide wireless communication services, such as allowing a UE or user equipment to establish a wireless connection to the RAN node, and sending and / or receiving data from one or more UEs. For example, after establishing a connection to a UE, the RAN node or network node (e.g., BS, eNB, gNB, CU / DU…) can forward data received from the network or core network to the UE, and / or forward data received from the UE to the network or core network. RAN nodes or network nodes (e.g., BS, eNB, gNB, CU / DU, etc.) can perform a wide variety of other radio functions or services, such as broadcasting control information to UEs (e.g., system information or on-demand system information), paging UEs when data to be delivered to them is available, assisting UEs in handover between cells, scheduling resources for uplink data transmission from (multiple) UEs and downlink data transmission to (multiple) UEs, and sending configuration information to configure one or more UEs. These are just a few examples of one or more functions that a RAN node or BS can perform.

[0026] User equipment or user node (user terminal, user equipment (UE), mobile terminal, handheld wireless device, etc.) can refer to portable computing devices that operate with or without a subscriber identification module (SIM), including but not limited to the following types of devices: mobile station (MS), mobile phone, cellular phone, smartphone, personal digital assistant (PDA), cell phone, device using a wireless modem (alarm or measuring device, etc.), laptop and / or touchscreen computer, tablet computer, tablet phone, game console, laptop, vehicle, drone, sensor and multimedia device, as an example, or any other wireless device. It should be understood that user equipment can also be (or can include) a virtually exclusive uplink-only device, an example of which is a camera or camcorder that loads image or video clips onto the network. Furthermore, user node can include user equipment (UE), user equipment, user terminal, mobile terminal, mobile station, mobile node, subscriber equipment, subscriber node, subscriber terminal, or other user node. For example, a user node can be used to communicate wirelessly with one or more network nodes (e.g., gNB, eNB, BS, AP, CU, DU, CU / DU) and / or with one or more other user nodes, regardless of the technology or radio access technology (RAT).

[0027] In 5G (which may be referred to as New Radio (NR)) (as an illustrative example), the core network 150 may be referred to as the 5G core network (5GC), which may include Access and Mobility Management Functions (AMF). For example, an AMF may include the following functions (e.g., some AMF functions may be supported in a single instance of an AMF): termination of the RAN Control Plane (CP) interface (N2), termination of the Non-Access Stratum (NAS) (or N1), NAS encryption and integrity protection, registration management, connection management, reachability management, mobility management, lawful interception, etc. The 5GC may also include Session Management Functions (SMF), which may include one or more of the following functions (one or more SMF functions may be supported in a single instance of an SMF): session management (e.g., session establishment, modification, and release, including tunnel maintenance between User Plane Functions (UPF) and BS 134), IP address allocation and management (including optional authorization), selection and control of (multiple) UPFs, configuring traffic routing at UPFs to route traffic to appropriate destinations, etc. In LTE (as an illustrative example), the core network 150 may be referred to as the Evolved Packet Core (EPC), which may include a Mobility Management Entity (MME) that can handle or assist user equipment in mobility / handover between BSs, one or more gateways that can forward data and control signals between the BS and a packet data network or the Internet, and other control functions or blocks.

[0028] Furthermore, the technologies described in this paper can be applied to various types of user equipment or data service types, or to user equipment that can run multiple applications of different data service types. New 5G (NR) development can support a variety of applications or data service types, such as Machine-Type Communication (MTC), Enhanced Machine-Type Communication (eMTC), Internet of Things (IoT) and / or Narrowband IoT user equipment, Enhanced Mobile Broadband (eMBB), and Ultra-Reliable and Low-Latency Communication (URLLC). Many of these new 5G (NR) related applications typically require higher performance than previous wireless networks.

[0029] The Internet of Things (IoT) can refer to a growing group of objects that can have internet or network connectivity, enabling them to send and receive information from other network devices. For example, many sensor-type applications or devices can monitor physical conditions or states and, for instance, send reports to servers or other network devices when events occur. Machine-type communication (MTC or machine-to-machine communication) can be characterized, for example, by the fully automated generation, exchange, processing, and actuation of data between intelligent machines with or without human intervention. Enhanced Mobile Broadband (eMBB) can support data rates significantly higher than those currently available in LTE.

[0030] Ultra-Reliable and Low-Latency Communication (URLLC) is a new type of data service or a new use case that can be supported for new radio (5G) systems. This enables emerging new applications and services such as industrial automation, autonomous driving, vehicle safety, and eHealth services. As an illustrative example, 3GPP aims to provide services with a corresponding Block Error Rate (BLER) of 10. -5 And reliable connections with U-plane (user / data plane) latency not exceeding 1ms. Therefore, for example, URLLC user equipment / UEs may require significantly lower block error rates and lower latency (with or without the need for high reliability simultaneously) compared to other types of user equipment / UEs. Thus, for example, URLLC UEs (or URLLC applications on UEs) may require much shorter latency compared to eMBB UEs (or eMBB applications running on UEs).

[0031] The technologies described herein can be applied to a wide variety of wireless technologies or wireless networks, such as 5G (New Radio (NR)), cmWave and / or millimeter-wave band networks, IoT, MTC, eMTC, eMBB, URLLC, 6G, etc.) or any other wireless network or wireless technology. These example networks, technologies, or data service types are provided as illustrative examples only.

[0032] 3GPP Release 18 studied and standardized signaling for dynamic spatial and power adaptation for Network Energy Saving (NES). Spatial and power adaptation is performed using a joint signaling framework for CSI reports. Specifically, CSI reports were enhanced in Release 18 to support multiple Channel State Information-Reference Signal (CSI-RS) configurations that can be associated with different antenna mute modes. Different sub-configurations are introduced within a single CSI report configuration, which can be associated with different antenna and / or power adaptation modes (e.g., different antenna mute modes and / or different power levels). Different antenna mute modes can allow one or more (or portions of) antenna elements or panels to save energy.

[0033] In version 18, the primary CSI report configuration can be configured to report one or more report quantities, such as one or more of the following: Rank Indicator (RI), Precoding Matrix Indicator (PMI), Channel Quality Indicator (CQI), or other report quantities, as well as other information such as beam or resource indicators, such as Channel State Information - Reference Signal Resource Indicator (CRI or cri) or Synchronization Signal Block Resource Indicator (SSBRI or ssbri). The primary CSI report configuration can also configure report types, such as periodic report types, semi-persistent report types, or non-periodic report types.

[0034] However, as required by Release 18, each sub-configuration within a single CSI reporting configuration will reuse (i.e., follow) the same report quantity (e.g., cri-RI-PMI-CQI, cri-RI-CQI, etc.) and the same report type (e.g., periodic, semi-persistent, or non-periodic report type) as the overall or main CSI reporting configuration. This lack of flexibility in sub-configurations is provided to reduce configuration overhead. Therefore, Release 18 requires that each sub-configuration within a CSI report must report the same (multiple) report quantities as the main CSI reporting configuration and must have or use the same report type as the main CSI reporting configuration. Thus, Release 18 provides limited or no flexibility in reporting CSI information for sub-configurations within a CSI reporting configuration; for example, it does not allow sub-configurations to report different report quantities or use different report types to report CSI information than the main CSI reporting configuration.

[0035] This could mean, for example, based on version 18: For periodic CSI reporting: If the network is using this NES antenna adaptation, multiple sub-configurations are configured. During each periodic reporting period, the UE must report the CSI for all sub-configurations, and for each sub-configuration, the CSI must include all reporting amounts configured for the overall or main CSI reporting configuration.

[0036] For non-periodic CSI reporting: The trigger state for non-periodic reporting needs to be configured with multiple sub-configurations. When triggered, the UE must report CSI (Channel State Information) for all sub-configurations, including all reporting amounts configured for the overall or main CSI reporting configuration for each sub-configuration.

[0037] For semi-persistent CSI reporting: The current configuration supports MAC-CE (Media Access Control Element) to enable / disable semi-persistent CSI reporting for different sub-configurations; however, this is a slow mechanism and is limited to the semi-persistent reporting type. Furthermore, activating a sub-configuration does not provide the flexibility to change the amount of CSI reporting required for that sub-configuration, meaning that the activated sub-configuration still needs to report the same amount of CSI reporting as the primary CSI reporting configuration.

[0038] One issue involves the significant overhead of CSI reporting from multiple antenna mute modes when many sub-configurations exist. The number of transport (Tx) antennas (or antenna elements) should increase from a maximum of 64 Tx antennas in 5G to 256 transport antennas or 512 Tx antennas in 6G (super mMIMO). As the number of Tx antennas (or antenna elements) increases, the number of spatial adaptation modes (or antenna mute modes) for which the UE should report performance also increases, and CSI feedback from multiple antenna mute modes can become very large. Furthermore, from both the UE's and the network's perspectives, always requesting UE CSI feedback for all antenna modes or antenna mute modes (many sub-configurations) can be highly inefficient, as the network must process CSI-RS transmissions for each of the many sub-configurations (different antenna modes), resulting in overhead in signaling and energy consumption.

[0039] Therefore, in version 18, there is a tight relationship or match between the report types and report volumes configured in the main or overall CSI reporting configuration and those used by each sub-configuration (e.g., each sub-configuration must now use the same report types and report the same (multiple) report volumes as the main or overall CSI reporting configuration). This is very inflexible for sub-configurations and can significantly increase reporting overhead as the number of antenna mute modes increases.

[0040] Therefore, a more flexible approach is provided for reporting Channel State Information (CSI) for one or more sub-configurations, where each sub-configuration does not need to use the same CSI reporting volume(s) and does not need to use the same CSI reporting type as the main or overall CSI configuration. Instead, according to an example embodiment, sub-configuration-specific CSI reporting volumes (e.g., the CSI reporting volume selected for that sub-configuration) and sub-configuration-specific CSI reporting types (e.g., the CSI reporting type selected for reporting CSI information for that sub-configuration) can be used to report CSI information for one or more sub-configurations of the CSI reporting configuration. This approach provides greater flexibility for reporting CSI information for sub-configurations and can significantly reduce signaling overhead and energy consumption.

[0041] According to an example embodiment, the UE (or user equipment) may receive a CSI reporting configuration that includes multiple sub-configurations. The UE may also receive a reporting quantity indication (or a first indication) that activates a CSI reporting quantity in a set of one or more CSI reporting quantities. After a reporting quantity for a sub-configuration is activated, that reporting quantity will be reported for that sub-configuration. The reporting quantity indication may be sub-configuration specific; for example, the reporting quantity may be sub-configuration specific or provided for a specific sub-configuration. Different reporting quantities may be received by the UE for different sub-configurations. Thus, for example, for each of one or more sub-configurations of the CSI reporting configuration, the UE may receive a sub-configuration specific reporting quantity indication that activates (or causes to activate) the sub-configuration specific reporting quantity for that sub-configuration. The UE may measure the activated CSI reporting quantity for the sub-configuration and then transmit a CSI report to the gNB including the measured activated CSI reporting quantity for the sub-configuration.

[0042] Some example CSI reporting quantities can be indicated to be reported (via a first indication). These example CSI reporting quantities may include a rank indicator (RI), a precoding matrix indicator (PMI), a channel quality indicator (CQI), or other reporting quantities, or combinations thereof. Some example reporting quantities may include, for example: cri-RI, cri-PMI, cri-CQI, cri-RI-PMI-CQI, cri-RI-CQI, cri-RSRP (reference signal received power), or other quantities or combinations thereof. These are merely some example CSI reporting quantities, and each CSI reporting quantity may include one or more quantities.

[0043] The UE can determine the sub-configuration-specific CSI reporting amount to be reported for each sub-configuration based on the received reporting indication (or first indication). Alternatively, in the case of one or more sub-configurations, the UE can determine the sub-configuration-specific reporting amount to be reported for each of the one or more sub-configurations based on the received sub-configuration-specific reporting amount indication (or first indication). The UE can then transmit a CSI report including the activated CSI reporting amount (or multiple activated CSI reporting amounts) for each of the one or more sub-configurations.

[0044] The UE can also receive a report type indication (e.g., a second indication) from a network node or gNB indicating the CSI report type for a sub-configuration (the CSI report type to be used to report CSI information for the sub-configuration). The UE can determine a sub-configuration-specific CSI report type based on the report type indication for each sub-configuration. The UE can report CSI information for a sub-configuration (e.g., including multiple active CSI report quantities) by transmitting a CSI report for the indicated report type (as indicated by the report type indication). The sub-configuration-specific CSI report type can be one of several CSI report types, and can be, for example, at least one of the following: periodic report type; non-periodic report type; or semi-persistent report type.

[0045] In this way, a more flexible method for reporting CSI information for sub-configurations can be provided, wherein a sub-configuration-specific reporting amount (e.g., one or more sub-configurations of the CSI reporting configuration are indicated and / or activated) can be reported for each sub-configuration, and / or a sub-configuration-specific reporting type (e.g., the indicated reporting type for each sub-configuration of one or more sub-configurations of the CSI reporting configuration) can be used to report CSI information for each sub-configuration.

[0046] Furthermore, in some cases, a sub-configuration indication or activation indication (e.g., a third indication) can be received by the UE to activate the sub-configuration. For example, once the sub-configuration is activated, the activated CSI reporting quantity can be reported for the sub-configuration via the indicated CSI reporting type. Alternatively, the UE receiving a reporting quantity indication to activate the CSI reporting quantity for the sub-configuration can also operate to activate the sub-configuration (e.g., in this case, the reporting quantity indication can operate to activate both the sub-configuration and the CSI reporting quantity).

[0047] Furthermore, the CSI reporting configuration may include a main CSI configuration for reporting CSI information, and multiple sub-configurations for reporting sub-configuration-specific CSI information, which includes the activated CSI reporting volume for each of the multiple sub-configurations. Thus, each sub-configuration may report a sub-configuration-specific reporting volume (as activated by a reporting volume indicator) and / or this information may be reported for each sub-configuration via a sub-configuration-specific reporting type (e.g., as indicated by a sub-configuration-specific reporting type indicator), wherein the CSI reporting volume and CSI reporting type for each sub-configuration may be independent of other sub-configurations and different from and / or independent of the CSI reporting volume and / or CSI reporting type for the main CSI configuration.

[0048] Furthermore, each of the multiple sub-configurations may be associated with one (or different) antenna mute mode, transmit power level (e.g., different transmit power levels or power offsets), and / or may be associated with a portion of bandwidth (e.g., different portions of bandwidth). Additionally, the CSI reporting configuration including the sub-configurations may be received via Radio Resource Control (RRC) messages, while report quantity indications (e.g., first indications), report type indications (e.g., second indications), and / or sub-configuration indications (e.g., third indications) may be received via Downlink Control Information (DCI) or Media Access Control (MAC) control elements (MAC CE).

[0049] Furthermore, for example, for each sub-configuration, the UE can transmit a CSI report for that sub-configuration, which may include a default CSI report amount for the sub-configuration or one or more activated CSI report amounts for the sub-configuration (if any CSI report amounts are activated). For example, if a default CSI report amount is specified by the sub-configuration, but no CSI report amount is activated, and the sub-configuration is activated, the UE can report the default CSI report amount for the sub-configuration. Additionally, for each sub-configuration, one or more received report amounts indicate a first report amount that can be deactivated (thus deactivating reports of that amount for the sub-configuration) and / or a second report amount that can be activated (thus activating reports of that amount).

[0050] Figure 2 This is a signaling diagram illustrating the operation of a network according to an example embodiment. Figure 3 This is a diagram illustrating CSI reporting configuration 310, which includes a main CSI reporting configuration 312 and one or more sub-configurations, such as sub-configuration #0 (e.g., associated with space mode or antenna mute mode #0), sub-configuration #1 (e.g., associated with space mode or antenna mute mode #1)... and sub-configuration #N (e.g., associated with space mode or antenna mute mode #N). Although as... Figure 3As shown, each sub-configuration is associated with a spatial mode (antenna mute mode), but one or more sub-configurations may alternatively be associated with a power level or power offset level or a portion of the bandwidth of the main configuration 312.

[0051] like Figure 2 As shown, UE 210 can communicate and / or connect to gNB 212 or other network nodes. Figure 2 Step 1, gNB 212 transmits CSI report configuration 310 to UE 210 (e.g., Figure 3 This includes the main configuration 312 of CSI report configuration 310 and one or more sub-configurations. Figure 2 At step 2, gNB 212 transmits the Channel State Information-Reference Signal (CSI-RS) received by UE 210, for example, CSI-RS transmissions corresponding to different spatial modes (antenna mute mode). Figure 2 In step 3, UE 210 measures one or more CSI report quantities for the primary configuration and one or more active CSI report quantities for each active sub-configuration. Also in step 3, UE 210 transmits CSI information via one or more CSI reports, for example, for the primary configuration and one or more active sub-configurations associated with different spatial modes. For example, UE 210 can transmit CSI information via report types and including one or more CSI report quantities for the primary configuration and each active sub-configuration. For example, UE 210 can measure and report only the CSI report quantities active for each (active) sub-configuration. For example, having the UE measure and report only the active CSI report quantities can reduce the UE's processing and signaling overhead. As described above, the number of activated CSI reports for each sub-configuration is specific to the sub-configuration (e.g., a set of activated CSI reports for a sub-configuration that may be separate, different and / or independent from the number of activated CSI reports for other sub-configurations, and separate, different and / or independent from the number of CSI reports to be reported for the main CSI configuration).

[0052] refer to Figure 3The main configuration 310 can configure the UE to report CSI information specific to the UE, and the sub-configurations can configure the UE to report specific CSI information for each sub-configuration (e.g., a default reporting amount or multiple activated reporting amounts for the sub-configuration). For example, a default CSI reporting amount for a sub-configuration can be provided to the UE or signaled via a sub-configuration (e.g., via a Radio Resource Control (RRC) configuration message), while the CSI reporting amount and / or CSI reporting type for a sub-configuration can be dynamically signaled to the UE via downlink control information (DCI) or media access control (MAC) control element (MAC CE) or other signals. Alternatively, the default CSI reporting amount can be signaled to the UE via dynamic signaling (e.g., DCI or MAC CE).

[0053] Therefore, a more flexible approach is provided, in which the main configuration and various sub-configurations can have or be configured to have different reporting volumes or sub-configuration-specific reporting volumes, and the various sub-configurations can be configured with different (or sub-configuration-specific) reporting types. Thus, for one or more sub-configurations, the UE can report sub-configuration-specific (multiple) CSI reporting volumes (e.g., the default CSI reporting volume indicated by the sub-configuration if no CSI reporting volume is activated, or the activated sub-configuration-specific (multiple) CSI reporting volumes), and the UE can report this CSI information for the sub-configuration via a sub-configuration-specific reporting type. In this way, for various sub-configurations, the UE does not need to report the same sub-configuration-specific CSI reporting volumes as it reports for the main configuration, and each sub-configuration does not need to use the same reporting type as the main configuration. Furthermore, within the sub-configurations of the CSI reporting configuration, each sub-configuration can have different or independent (sub-configuration-specific) (multiple) CSI reporting volumes and / or CSI reporting types, which provides improved flexibility for reporting CSI information for one or more sub-configurations.

[0054] Figure 4 This is a flowchart illustrating the operation of a user equipment according to an example embodiment. Operation 410 includes the user equipment (e.g., UE) receiving a Channel State Information (CSI) report configuration including multiple sub-configurations from a network node. Operation 420 includes the user equipment receiving from the network node a first indication (e.g., a reporting amount indication) for a sub-configuration among the multiple sub-configurations, the first indication activating a CSI reporting amount for the sub-configuration, wherein the first indication is specific to the sub-configuration. Furthermore, operation 430 includes the user equipment transmitting a CSI report to the network node, the CSI report including the activated CSI reporting amount for the sub-configuration.

[0055] Figure 5This is a flowchart illustrating the operation of a network node according to an example embodiment. Operation 510 includes transmitting a Channel State Information (CSI) report configuration, comprising multiple sub-configurations, from the network node (e.g., gNB) to the user equipment. Operation 520 includes transmitting from the network node to the user equipment a first indication (e.g., a reporting amount indication) for one of the multiple sub-configurations, the first indication activating a CSI reporting amount for the sub-configuration, wherein the first indication is specific to the sub-configuration. Furthermore, operation 530 includes receiving a CSI report from the user equipment by the network node, the CSI report including the activated CSI reporting amount for the sub-configuration.

[0056] Figure 6 This is a flowchart illustrating the operation of a user equipment according to another example embodiment. Operation 610 includes the user equipment receiving a Channel State Information (CSI) report configuration comprising multiple sub-configurations from a network node. Operation 620 includes the user equipment receiving from the network node an indication of a CSI report type for one of the multiple sub-configurations, wherein the indication or CSI report type is specific to the sub-configuration. Operation 630 includes the user equipment transmitting a CSI report of the indicated CSI report type for the sub-configuration to the network node.

[0057] Figure 7 This is a flowchart illustrating the operation of a network node according to another example embodiment. Operation 710 includes the network node transmitting a Channel State Information (CSI) report configuration comprising multiple sub-configurations to a user equipment. Operation 720 includes the network node transmitting from the user equipment an indication of a CSI report type for one of the multiple sub-configurations, wherein the indication or CSI report type is specific to the sub-configuration. And, operation 730 includes the network node receiving a CSI report of the indicated CSI report type for the sub-configuration from the user equipment.

[0058] For each of the multiple sub-configurations, the UE may receive a report quantity indication (e.g., a first indication) that activates a CSI report quantity specific to the sub-configuration; and for each of the multiple sub-configurations, the UE may receive or activate a report type indication (e.g., a second indication) for a CSI report type specific to the sub-configuration, wherein the report type indication (e.g., the second indication) or the CSI report type is specific to the sub-configuration.

[0059] The UE can determine the CSI reporting amount to be activated for the reporting sub-configuration based on the reporting amount indication (e.g., a first indication) received by the user equipment and based on the received first indication.

[0060] A network node (e.g., a gNB) can transmit information about a set of CSI reporting quantities, and a UE can receive information indicating a set of CSI reporting quantities, wherein the CSI reporting quantities activated based on a first indication (e.g., a reporting quantity indication) are CSI reporting quantities within the set of CSI reporting quantities. The indicated set of CSI reporting quantities may be common to many sub-configurations (or provided or signaled to many sub-configurations), and the first indication may specifically activate one or more CSI reporting quantities for a particular sub-configuration within the set of CSI reporting quantities. Alternatively, the indicated set of CSI reporting quantities may be used for a particular sub-configuration, and the first indication may specifically activate one or more of them for that particular sub-configuration.

[0061] A network node (e.g., gNB) may transmit a second indication for a subconfiguration and a UE may receive a second indication for a subconfiguration (e.g., a report type indication), wherein the CSI report type may include at least one of the following report types: periodic report type; non-periodic report type; or semi-persistent report type, and wherein the second indication or CSI report type is specific to the subconfiguration.

[0062] Sub-configurations can be associated with different things, such as: each of a plurality of sub-configurations can be associated with an antenna mute mode; each of a plurality of sub-configurations can be associated with a transmit power level or transmit power level offset; each of a plurality of sub-configurations can be associated with a portion of the bandwidth of the main configuration of the CSI report configuration, wherein the portion of the bandwidth associated with each sub-configuration is less than the bandwidth of the main configuration; or at least one of a plurality of sub-configurations can be associated with an antenna mute mode, and wherein at least one of a plurality of sub-configurations can be associated with a transmit power level or transmit power level offset.

[0063] In addition, the CSI reporting configuration may include: a main configuration or CSI reporting configuration for reporting CSI information; and multiple sub-configurations for reporting CSI information specific to the sub-configurations, which may include at least one CSI reporting quantity for each of the multiple sub-configurations.

[0064] As described above, the report type indication can be received by the UE via dynamic signaling to indicate the CSI report type for a sub-configuration. The UE can transmit CSI reports via the indicated or activated CSI report type for a sub-configuration, which includes the activated CSI report amount for each of the multiple sub-configurations.

[0065] In some cases, at least one of multiple sub-configurations may indicate a default CSI reporting amount; wherein the absence of a received reporting amount indication (e.g., a first indication) for a sub-configuration indicates that a default CSI reporting amount should be reported. Furthermore, for example, each of the multiple sub-configurations may include a set of one or more CSI reporting amounts, which may be reported by the UE (or user equipment) for the sub-configuration if a CSI reporting amount in that set is activated or indicated as the default CSI reporting amount. Additionally, for each sub-configuration, the UE may transmit a report (e.g., using a report type indicated by a report type indication) that includes the default CSI reporting amount for the sub-configuration (e.g., if no CSI reporting amount is activated) or one or more activated CSI reporting amounts for the sub-configuration.

[0066] Reporting volume indications can be used to activate and / or deactivate one or more CSI reporting volumes for one or more sub-configurations. For example, a reporting volume indication (e.g., a first indication) may include an indication for deactivating a first CSI reporting volume and an indication for activating a second CSI reporting volume to be reported for a sub-configuration. Furthermore, the UE may receive an indication for deactivating a first CSI reporting volume previously activated for a first sub-configuration, causing the UE to stop reporting the first CSI reporting volume for the first sub-configuration. Additionally, for example, the UE may receive information and an indication that fails to indicate the activation of a first CSI reporting volume previously activated for a first sub-configuration, which is used to activate a second CSI reporting volume for the first sub-configuration, causing the UE to stop reporting the first CSI reporting volume for the first sub-configuration and report the second CSI reporting volume for the first sub-configuration.

[0067] According to an example embodiment, the UE can receive a CSI reporting configuration including one or more sub-configurations from a network node (e.g., a gNB), where each sub-configuration may be associated with, for example, an antenna mute mode. A CSI reporting configuration including multiple sub-configurations may include (or may be configurable) a set of CSI reporting quantities, where some CSI reporting quantities in the set can be activated, and some CSI reporting quantities in the set can be deactivated. For example, activation and / or deactivation of the sub-configuration-specific CSI reporting quantities(s) can be performed via dynamic signaling, such as transmitting DCI or MAC CE to the UE via the network node, for example, to activate (or enable) and / or deactivate (or deactivate) one or more sub-configuration-specific CSI reporting quantities for one or more sub-configurations.

[0068] The UE can also receive dynamic indications or dynamic signaling from network nodes (e.g., via DCI or MAC CE), which indicate which CSI reporting volume(s) to activate and / or deactivate for a given sub-configuration (e.g., dynamic signaling can be used to activate and / or deactivate one or more (sub-configuration-specific) CSI reporting volumes for each sub-configuration). Based on the received CSI reporting configuration (which may indicate a set of CSI reporting volumes) and dynamic signaling (e.g., which may indicate the activation and / or deactivation of one or more CSI reporting volumes from the set of CSI reporting volumes for each sub-configuration), the UE can determine the CSI reporting volume to be reported for each sub-configuration. Furthermore, based on information provided in the CSI reporting configuration or dynamic signaling (which may indicate a sub-configuration-specific CSI reporting type for each of the one or more sub-configurations), the UE can determine the CSI reporting type to be used for reporting CSI information (e.g., the default CSI reporting volume or multiple activated CSI reporting volumes for each of the one or more sub-configurations of the CSI reporting configuration). Then, for each of one or more sub-configurations, the UE can determine the amount of CSI reports to be reported and / or the type of CSI reports to be used to report the amount of CSI reports, and can determine the size of the CSI reports to be triggered or transmitted to the network node.

[0069] Additionally, at least one sub-configuration of the CSI reporting configuration can indicate the codebook type to be used by the UE to report at least one activated CSI reporting quantity for the sub-configuration, wherein the codebook type is specific to the sub-configuration. For example, the main CSI configuration of the CSI reporting configuration can indicate that a Type II codebook will be used to report CSI information for the main CSI configuration, and one or more sub-configurations can indicate a sub-configuration-specific codebook type (e.g., Type I codebook, or Type II codebook, or other codebook type) to be used by the UE to report activated CSI reporting quantities for the sub-configuration. For example, the main CSI configuration indicates that a Type II codebook should be used to report CSI information for the main CSI configuration; sub-configuration #1 indicates that a Type I codebook will be used to report activated CSI reporting quantities for sub-configuration #1; and sub-configuration #2 indicates that a Type II codebook will be used to report activated CSI reporting quantities for sub-configuration #2. Each sub-configuration can indicate a (sub-configuration specific) codebook type that is independent of the codebook type to be used (or configured for use) by other sub-configurations and / or configured for use by the main CSI configuration.

[0070] Furthermore, the use of sub-configuration-specific (multiple) CSI report volumes, sub-configuration-specific report types, and / or sub-configuration-specific codebook types for one or more sub-configurations may refer to or include (multiple) CSI report volumes, CSI report types, and / or codebook types indicated or configured for each sub-configuration, which may be separate, different, and / or independent from (multiple) CSI report volumes, CSI report types, and / or codebook types indicated or configured for other sub-configurations of the main CSI configuration and / or CSI reporting configuration.

[0071] Example: A set of CSI reporting quantities may include, for example: cqi-ri-pmi, broadband cqi, and type 1-pmi.

[0072] In one example, the network can enable / disable (activate or deactivate) certain CSI reporting quantities for each sub-configuration (e.g., each space mode or each antenna mute mode, which is associated with the sub-configuration) after configuration. For example, for all sub-configurations that are not currently in use, the CSI reporting quantity including "pmi" reporting can be disabled (deactivated) in the CSI reporting configuration, while initially only the "wideband cqi" quantity can be activated to maintain general monitoring performance.

[0073] In one example, a network node may instruct to dynamically enable certain CSI reporting volumes (e.g., cqi-ri-pmi) for a short period of time to temporarily explore the performance of certain sub-configurations. This activation can be done based on the current load level and the current group of active UEs.

[0074] Note that the sub-configuration used by the network in a given time slot / period will depend on a complete set of scheduled UEs within that time slot / period and is most heavily influenced by UEs (e.g., cell edge UEs). Therefore, the sub-configuration to be used can also change when the set of UEs with data changes. And this can also occur very dynamically based on UE mobility.

[0075] Additionally, the network can dynamically activate / deactivate reporting (or perform reporting) types (e.g., periodic, aperiodic, semi-persistent) for a given sub-configuration. In other words, the reporting type is decoupled from the antenna mute resource configuration, thereby enabling dynamic activation or deactivation of CSI reporting types for each sub-configuration.

[0076] For example, a single 8-port CSI-RS resource configuration can be used to provide periodic, aperiodic, or semi-persistent CSI reporting based on the activated CSI reporting type. For semi-persistent or aperiodic reporting in a sub-configuration, the network (e.g., network nodes) can indicate the uplink (e.g., Physical Uplink Shared Channel (PUSCH)) resources to be used for reporting CSI information. If no indication is given, the UE can use the resources provided in the CSI reporting configuration. This is in Figure 9 As shown in the diagram. This allows the network to flexibly request rapid, non-periodic reports for different sub-configurations and determine which sub-configuration may require periodic or more frequent reporting.

[0077] Figure 8 This is a diagram illustrating flexible multi-CSI reporting according to an example embodiment. (Reference) Figure 8 UE 802 can communicate with gNB 804. At 810, gNB 804 transmits RRC configuration, which may include CSI reporting configuration, which includes one or more sub-configurations, such as subConfig#1, subConfig#2, and subConfig#3. One or more sub-configurations may indicate a default CSI reporting amount. For example, the CSI reporting configuration transmitted to UE 802 at 810 may indicate a default CSI reporting amount for cqi-ri-pmi for subConfig#1. In this example, no default CSI reporting amount is configured for subConfig#2 or subConfig#3.

[0078] refer to Figure 8 Resources have been configured (e.g., for CSI reporting times 814, 820, 824, and 830) and UE reporting for CSI information is indicated to UE 802 via the CSI reporting configuration at 810. Therefore, UE 802 can measure any default or activated CSI reporting quantity for one or more sub-configurations, and then report these reporting quantities to gNB 804 using the reporting type indicated by dynamic signaling for the sub-configuration, such as at CSI reporting times provided for persistent reporting. At CSI reporting time 814, UE 802 can transmit a CSI report including periodic reports (if indicated by dynamic signaling), which includes the default reporting quantity for cqi-ri-pmi for subConfig#1, since UE 802 has not yet received dynamic signaling activating any set of CSI reporting quantities for subConfig#1. Therefore, at 812 and for CSI reporting time 814, UE 802 will report the default reporting quantity (cqi-ri-pmi) to gNB 804.

[0079] In addition, such as Figure 8 As shown, at 816, UE 802 receives dynamic signaling from gNB 804, which indicates CSI reporting quantity #1 for subConfig#2 and CSI reporting quantity #2 for subConfig#3, and its operation is to activate or enable these CSI reporting quantities for subConfig#2 and subConfig#3. No CSI reporting quantity is indicated for subConfig#1; therefore, the UE will continue to report the default CSI reporting quantity for subConfig#1, while also reporting the activated CSI reporting quantities for subConfig#2 and subConfig#3. At 818 and 822, during CSI reporting times 820 and 824 respectively, the UE transmits CSI reports or CSI information, including: the default CSI reporting quantity (cqi-ri-pmi) for subConfig#1 (because UE802 has not yet received an indication of the CSI reporting quantity for subConfig#1, the CSI reporting quantity for subConfig#1 has not yet been activated, and the default CSI reporting quantity for subConfig#1 will be reported), the activated CSI reporting quantity #1 (cqi-ri) for subConfig#2 (which is activated at 816 via dynamic signaling), and the activated CSI reporting quantity #2 (ri) for subConfig#3 (which is activated at 816 via dynamic signaling).

[0080] refer to Figure 8At 826, UE 802 receives dynamic signaling (e.g., DCI or MAC CE) that only indicates CSI reporting quantity #3 for subConfig#2 (but does not indicate or activate CSI reporting quantities for subConfig#1 or subConfig#3). In this case, because a default CSI reporting quantity has not yet been configured for subConfig#3 (via RRC configuration at 810), and because the dynamic signaling at 826 fails to include a CSI reporting quantity for subConfig#3 (therefore, the previously activated CSI reporting quantity will be deactivated for subConfig#3), the next CSI report at 828 during CSI reporting timing 830 will not include a CSI reporting quantity for subConfig#3. At 828, UE 802 will transmit a CSI report that includes the default CSI reporting quantity (cqi-ri-pmi) for subConfig#1 and the activated (via signaling 826) reporting quantity #3 (cqi-ri-pmi) for subConfig#2 (activated at 826). In this example, dynamic signaling at 816 and 826 can indicate, for example, persistent report types for subConfig#1, subConfig#2, and subConfig#3. Resources for persistent reporting (e.g., time-frequency resources to be used by the UE to transmit persistent reports during CSI reporting times) can be provided or indicated to UE 802 via an RRC message at 810 or via dynamic signaling.

[0081] Figure 9This diagram illustrates flexible multi-CSI reporting according to another example embodiment, where resources are configured for uplink timings of semi-persistent or non-periodic reporting. In this example, dynamic signaling at 920 indicates the CSI reporting quantity #1 for subConfig#2 and the reporting quantity #2 for subConfig#3, and also indicates the reporting type for semi-persistent or non-periodic reporting for subConfig#2 and subConfig#3, and further indicates the resources to be used for reporting. Therefore, dynamic signaling at 920 indicates the CSI reporting quantity (causing its activation) and the CSI reporting type for each of subConfig#2 and subConfig#3. Since no CSI reporting quantity or CSI reporting type is indicated for subConfig#1 via dynamic signaling 920, the default CSI reporting quantity for subConfig#1 is reported at the next CSI reporting timings 924 and 930 via the default CSI reporting type for subConfig#1, 922. Based on the dynamic signaling at 920, CSI reports for subConfig#2 and subConfig#3 will be transmitted at 926 during the indicated uplink timing 928, based on the newly scheduled time-frequency resources (indicated via the dynamic signaling at 920). Later, the UE may receive another dynamic signaling indicating the CSI report quantity #3 for subConfig#2. The report type for subConfig#2 can be indicated as periodic (alternatively, uplink resources may not be indicated, which implicitly means that reports for subConfig#2 should use periodic resources (periodic reporting)). Therefore, the UE can report the default CSI report quantity for subConfig#1 and the dynamically indicated CSI report quantity for subConfig#2 in the next periodic CSI report timing.

[0082] Figure 10This is a diagram illustrating flexible multi-CSI reporting according to another example embodiment. UE 802 can communicate or connect to gNB (or other network node) 804. At step 1, UE 802 transmits an RRC message including a CSI reporting configuration, which includes: a report quantity indicating the size of the CSI report or the size of the report data of the CSI report, a set of CSI report quantities (reportQuantitySubset), a first sub-configuration identified as subConfig#1 (CSI-ReportsubConfig#1), and a second sub-configuration identified as subConfig#2 (CSI-ReportsubConfig#2), wherein both subConfig#1 and subConfig#2 are inactive (therefore, the report quantities of these subConfigs will not be reported at this time). Furthermore, a default CSI report quantity (reportQuantity = default value) is indicated for subConfig#1, but no default CSI report quantity is indicated for subConfig#2. UE 802 sends an acknowledgment (ACK) at step 2.

[0083] exist Figure 10 At step 3, gNB 804 transmits dynamic signaling or dynamic indication (e.g., via DCI or MAC CE) to UE 802. The dynamic signaling or dynamic indication activates subConfig#1 (the CSI report quantity not indicated via dynamic signaling) and subConfig#2 (reportQuantity#1 is indicated or activated for subConfig#1). Figure 10 Step 4 involves the UE sending an ACK.

[0084] exist Figure 10In step 5, based on the dynamic signaling received in step 3, UE 802 activates subConfig#1, where the CSI report quantity is set to the default CSI report quantity (since the dynamic signaling in step 3 does not indicate the CSI report quantity, the default CSI report quantity will be used to report subConfig#1); and activates subConfig#2, where reportQuantity is set to reportQuantity#1. The UE uses the default uplink resources provided in the CSI report configuration to transmit these CSI reports (e.g., periodic reports) for subConfig#1 and subConfig#2. UE 802 determines the UCI bits and CSI report size (e.g., for both subConfig#1 and subConfig#2) based on the report quantity of each activated subconfiguration. In step 6, UE 802 transmits (multiple) CSI reports via the uplink resources for subConfig#1 and subConfig#2.

[0085] Figure 11 This is a diagram illustrating a flexible multi-CSI report according to yet another example embodiment. Figure 11 and Figure 10 The diagrams are similar or identical, with differences described below. Figure 11 In step 1, the uplink resource list can be indicated in the CSI report configuration. Figure 11 At step 3, dynamic signaling (dynamic indication or dynamic activation) indicates the uplink resources for subConfig#2 (and indicates reportQuantity#1 for subConfig#2). Therefore, in this example, an aperiodic or semi-persistent report type can be indicated for subConfig#2 at step 3, and the uplink resources for this CSI report for subConfig#2 can be indicated. Figure 11 In step 5, the UE determines the uplink resources for transmitting the CSI report for subConfig#2 based on the uplink resources indicated in step 3. Figure 11 In step 6, UE 802 transmits a CSI report for subConfig#2 via the uplink resources indicated by the dynamic signaling in step 3, and can transmit a CSI report for subConfig#1 (or any or all subconfigurations) via the resources indicated by the CSI report configuration in step 1.

[0086] Figure 12 This is a diagram illustrating the operation of a user equipment (or UE) according to an example embodiment. Figure 12At step 1, the UE receives an RRC configuration with CSI reports for one or more sub-configurations (e.g., the UE receives a CSI report configuration including one or more sub-configurations). Figure 12 In step 2, the UE check should be included in the sub-configuration of the report. Figure 12 In step 3, the UE determines whether it has received dynamic signaling. If no dynamic signaling is received, the process proceeds to step 4, where the UE prepares a CSI report without any sub-configurations, assuming no sub-configurations are activated, and transmits the report on the uplink resources configured in the CSI report configuration of step 1 (or on default resources such as periodic UL resources). If sub-configuration activation is not required, the default reporting amount will be reported for the sub-configurations (those sub-configurations that indicate the default CSI reporting amount in the sub-configuration). Otherwise, a CSI report is prepared in step 4 without reporting any sub-configurations because no sub-configurations are activated.

[0087] exist Figure 12 In step 3, if dynamic signaling is received, then in step 7, for the listed sub-configurations to be activated, the UE sets the reporting quantity to the corresponding value indicated in the dynamic indication / signaling, or sets the reporting quantity to the default value of the reporting quantity (if no reporting quantity for the sub-configuration is indicated in the dynamic signaling), and for the deactivated sub-configurations, removes them from the list to be reported. Figure 12 At step 8, the UE determines the UCI bits for the CSI report size based on the reporting volume for each subConfig (for each subConfig). Figure 12 In step 5, the UE determines whether uplink resources have been received in dynamic signaling. If yes, a CSI report is prepared in step 6, which includes the sub-configurations to be reported via the indicated uplink resources (indicated via dynamic signaling). If no, proceed to step 4, where the UE prepares a CSI report including reports for at least one sub-configuration(s) indicated to be active in step 7, and transmits the report on the uplink resources configured as in the CSI report configuration of step 1 (or on default, such as periodic UL resources), since no uplink resources were provided in step 5.
