Response of user equipment (UE) to channel state information (CSI) reporting of network requests for machine learning

Abstract

A method for wireless communication by a user equipment (UE) includes receiving a request for a channel state information (CSI) report of a first type from a network. The first type of CSI report includes a number of reference signal received power (RSRP) values and / or signal-to-interference noise ratio (SINR) values greater than a first threshold level in a single CSI reporting opportunity, and / or an accuracy requirement greater than a second threshold level. The method sends a message indicating whether the UE will provide the CSI report. When the message indicates that the UE is to provide the CSI report, the method receives scheduling information for transmission of the CSI report and a signal associated with the CSI report. The method transmits the CSI report for the signal associated with the CSI report according to the scheduling information.

Description

Technical Field

[0001] This disclosure relates in general to wireless communications, and more specifically to the response of a user equipment (UE) to a network request for a special channel state information (CSI) feedback report for purposes such as machine learning. Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP). Narrowband (NB) Internet of Things (IoT) and Enhanced Machine-Type Communications (eMTC) are enhancement sets of LTE for machine-type communications.

[0003] A wireless communication network may include multiple base stations (BSs) capable of supporting communication for multiple user equipment (UEs). UEs can communicate with the base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, and an uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail, a BS may be referred to as a Node B, Evolved Node B (eNB), gNB, Access Point (AP), Radio Headend, Transmit and Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0004] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (also known as 5G) is an enhancement set of the LTE mobile standard released by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL), and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards. Summary of the Invention

The first type of CSI report includes the number of Reference Signal Received Power (RSRP) values ​​and / or Signal-to-Interference-Noise Ratio (SINR) values ​​greater than a first threshold level at a single CSI report time, and / or accuracy requirements greater than a second threshold level.

The processor is also configured, in response to the request, to send a message indicating whether the UE will provide the CSI report. The processor is further configured, in response to the message indicating that the UE will provide the CSI report, to receive from the network scheduling information for the transmission of the CSI report and a signal associated with the CSI report. The processor is configured to, according to the scheduling information, transmit the CSI report for the signal associated with the CSI report.

[0007] In other aspects of this disclosure, a method of wireless communication by a network device includes sending a request to a user equipment (UE) for a first type of Channel State Information (CSI) report. The first type of CSI report includes the number of Reference Signal Received Power (RSRP) values ​​and / or Signal-to-Interference-Noise Ratio (SINR) values ​​greater than a first threshold level at a single CSI report time, and / or accuracy requirements greater than a second threshold level. The method also includes, in response to the request, receiving a message indicating whether the UE will provide a CSI report. The method further includes, in response to the message indicating that the UE will provide the CSI report, sending to the UE scheduling information for the transmission of the CSI report and a signal associated with the CSI report.

[0021] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings, those skilled in the art will recognize that the scope of this disclosure is intended to cover any aspect of this disclosure, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or method may be implemented using any number of the aspects set forth. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using other structures, functions, or structures and functions other than or supplementing the various aspects of this disclosure set forth. It should be understood that any aspect of this disclosure may be embodied by one or more elements of the claims.

[0022] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0023] It should be noted that although the aspects may be described using terms commonly associated with 5G and subsequent wireless technologies, the aspects of this disclosure may be applied in other generation-based communication systems, such as and including 3G and / or 4G technologies.

[0024] Data can be collected from user equipment (UE) for model training on the UE side or chipset vendor side. Data can also be collected for network-side artificial intelligence (AI) or machine learning (ML) models. In some implementations, these models may be beam management specific. Reports from the UE for network-side models should take into account overhead, UE complexity, and power consumption.

[0025] Data collection for AI / ML models at the base station (e.g., gNB) may specify more complex Layer 1 (L1) reference received signal power (RSRP) and / or signal-to-noise-plus-interference ratio (SINR) feedback (more generally referred to as Channel State Information (CSI) reporting or “special” CSI reporting) for base station-side beam prediction. More complex reporting may be undesirable for the UE due to increased UE power consumption. More complex L1-RSRP / SINR feedback may include a large number of beams or more stringent L1-RSRP / SINR measurement accuracy requirements than older reporting methods.

[0026] For example, a standard CSI report may include up to four reported beams, while a special report may include eight. With older reporting, the UE can stop measuring beams predicted to be weak to reduce the power consumed by beam measurement. However, the base station may still be interested in weak beams used for data collection or base station-side time-domain beam prediction. Therefore, in such cases, the UE may consume additional power.

[0027] Furthermore, to train AI / ML models with good predictive performance or perform base station-side beam prediction, the L1-RSRP measurement accuracy required for data collection may be more stringent than that for L1-RSRP measurements used for routine purposes. To meet such requirements, the UE may need to use more antenna elements or open additional panels, which could result in higher power consumption.

[0028] According to various aspects of this disclosure, the UE may decide whether to provide more complex CSI feedback requested by the base station. Depending on the UE's willingness to assist network-side data collection and / or network-side beam prediction, when requested by the network to provide a more complex CSI report, the UE may indicate whether it will provide such a report. This indication may be transmitted via static radio resource control (RRC) signaling (e.g., via UE capability reporting). In other aspects, the indication may be sent on demand or in response to event triggering. The UE's willingness to provide a more complex report to the base station may depend on certain conditions, such as UE computational complexity or power budget.

[0029] According to various aspects of this disclosure, special or more complex reports are defined based on certain criteria. A first criterion for determining whether a report is complex (or special) is a higher number of L1-RSRP / SINR measurements associated with more beams in a single Channel State Information (CSI) reporting event. This criterion may be further based on the first CSI report including at least one more L1-RSRP / SINR measurement than a traditional CSI report for each CSI reporting event. This criterion may further depend on whether the number of candidate beams associated with the first CSI report exceeds a certain threshold number. A second criterion for determining whether a report is special or complex relates to the accuracy requirements of the report. The reported L1-RSRP / SINR measurements should meet the more stringent accuracy requirements for special or complex reports.

[0030] In some aspects of this disclosure, the network explicitly indicates the purpose of the first CSI report. In these aspects, the UE determines whether to support the network-requested first CSI report based on the purpose indicated by the network.

[0031] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques (such as responding to requests for specific CSI reports) can allow the UE to better manage its power consumption.

[0032] Figure 1This is an illustration of a network 100 in which various aspects of the present disclosure may be practiced. Network 100 may be a 5G or NR network, or some other wireless network (such as an LTE network). Wireless network 100 may include multiple BS 110s (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B, access point, Transmit and Receive Point (TRP), network node, network entity, etc. A base station may be implemented as a converged base station, a decomposed base station, an Integrated Access and Backhaul (IAB) node, a relay node, a sidelink node, etc. A base station may be implemented in a converged or monolithic base station architecture, or alternatively, in a decomposed base station architecture, and may include one or more of a central unit (CU), a distributed unit (DU), a radio unit (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC.

[0033] Each BS can provide communication coverage for a specific geographic area. In 3GPP, depending on the context in which the term is used, the term "cell" can refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area.

[0034] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access for UEs with a service subscription. A picocell can cover a relatively small geographic area and can allow unrestricted access for UEs with a service subscription. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access for UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “AP,” “node B,” “5G NB,” “TRP,” and “cell” are used interchangeably.

[0035] In some respects, the cell does not need to be stationary, and the geographical area of ​​the cell can be moved depending on the location of the mobile BS. In some respects, the BS can use any suitable transport network to interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections, virtual networks, etc.).

[0036] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and forward those data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, relay base station, repeater, etc.

[0037] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 watts to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0038] For example, BS 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and core network 130 can exchange communication via backhaul link 132 (e.g., S1, etc.). Base station 110 can communicate with each other directly or indirectly (e.g., via core network 130) via other backhaul links (e.g., X2, etc.).

[0039] The core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may be a control node that processes signaling between UE120 and the EPC. All user IP packets can be transmitted through the S-GW, which itself may be connected to the P-GW. The P-GW provides IP address allocation and other functions. The P-GW may be connected to the network operator's IP services. The operator's IP services may include the Internet, intranet, IP Multimedia Subsystem (IMS), and packet switching (PS) streaming services.

[0040] Core network 130 can provide user authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions. One or more of base stations 110 or access node controllers (ANCs) can interface with core network 130 via backhaul links 132 (e.g., S1, S2, etc.) and can perform radio configuration and scheduling for communication with UE 120. In some configurations, the various functions of each access network entity or base station 110 can be distributed across various network devices (e.g., radio headends and access network controllers) or consolidated into a single network device (e.g., base station 110).

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. UEs may be cellular phones (e.g., smartphones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptops, cordless phones, wireless local loop (WLL) stations, tablet devices, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices or equipment, biometric sensors / devices, wearable devices (smartwatches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), entertainment devices (e.g., music or video devices, or satellite radios), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, GPS devices, or any other suitable device configured to communicate via wireless or wired media.

[0042] One or more UEs 120 can establish Protocol Data Unit (PDU) sessions for network slices. In some cases, UE 120 can select network slices based on application or subscription services. By assigning different network slices to different applications or subscriptions, UE 120 can improve its resource utilization within the wireless network 100 while also meeting the performance specifications of each application of UE 120. In some cases, this can be achieved through an AMF (Application-Specific Function) associated with one or both of base station 110 and core network 130. Figure 1 (Not shown in the image) to serve the network slice used by UE 120. In addition, session management of the network slice can be performed by the Access and Mobility Management Function (AMF).

[0043] UE 120 may include a Channel State Information (CSI) reporting module 140. For brevity, only one UE 120d is shown as including the CSI reporting module 140. The CSI reporting module 140 may receive from the network a request for a first type of Channel State Information (CSI) report. The first type of CSI report includes the number of Reference Signal Received Power (RSRP) values ​​and / or Signal-to-Interference-Noise Ratio (SINR) values ​​greater than a first threshold level and / or accuracy requirements greater than a second threshold level at a single CSI reporting time. The CSI reporting module 140 may also, in response to the request, send a message indicating whether the UE will provide a CSI report. The CSI reporting module 140 may also, in response to the message indicating that the UE will provide a CSI report, receive from the network scheduling information for the transmission of the CSI report and signals associated with the CSI report. The CSI reporting module 140 may also, according to the scheduling information, send a CSI report for the signals associated with the CSI report.

[0044] Core network 130 or base station 110 or any other network device (e.g., such as...) Figure 3 The base station 110a shown may include a CSI reporting module 138. For brevity, only one base station 110a is shown as including the CSI reporting module 138. The CSI reporting module 138 may send a request to the user equipment (UE) for a first type of Channel State Information (CSI) report. The first type of CSI report includes the number of Reference Signal Received Power (RSRP) values ​​and / or Signal-to-Interference-Noise Ratio (SINR) values ​​greater than a first threshold level and / or accuracy requirements greater than a second threshold level in a single CSI report time. In response to the request, the CSI reporting module 138 may also receive a message indicating whether the UE will provide a CSI report. In response to the message indicating that the UE will provide a CSI report, the CSI reporting module 138 may also send to the UE scheduling information for the transmission of the CSI report and a signal associated with the CSI report. The CSI reporting module 138 may also receive a CSI report for the signal associated with the CSI report according to the scheduling information.

[0045] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. For example, MTC and eMTC UEs include robots, drones, remote devices, sensors, meters, monitors, location tags, etc., capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or from a network, such as a wide area network (WAN) like the Internet or a cellular network, via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included in a housing that houses the components of UE 120, such as processor components, memory components, etc.

[0046] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as a radio technology, air interface, etc. Frequency can also be referred to as a carrier, frequency channel, etc. Within a given geographical area, each frequency can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0047] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, mesh networks, etc.). In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein, performed by base station 110. For example, base station 110 may configure UEs 120 via downlink control information (DCI), radio resource control (RRC) signaling, media access control-control element (MAC-CE), or via system information (e.g., system information block (SIB)).

[0048] As indicated above, Figure 1 This is provided merely as an example. Other examples are available in conjunction with [the relevant documentation / information]. Figure 1 The examples described are different.

[0049] Figure 2A block diagram of a design 200 for a base station 110 and a UE 120 is shown. The base station and the UE can be... Figure 1 One of the base stations in the base station and Figure 1 One of the UEs in the UE. Base station 110 may be equipped with T antennas 234a to 234t, and UE 120 may be equipped with R antennas 252a to 252r, where generally, T≥1 and R≥1.

[0050] At base station 110, transmit processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and decoding schemes (MCS) for each UE based at least in part on the Channel Quality Indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Reducing the MCS decreases throughput but increases transmission reliability. Transmit processor 220 can also process system information (e.g., semi-static resource partitioning information (SRPI) and other) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process the corresponding output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM), etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively. Position coding can be used to generate synchronization signals to convey additional information, according to various aspects described in more detail below.

[0051] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process these input samples (e.g., for OFDM, etc.) to obtain the received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor can determine the Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or Channel Quality Indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0052] On the uplink, at UE 120, the transmitting processor 264 can receive data from data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.) from controller / processor 280, and process the data and control information. The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-decoded by the TX MIMO processor 266, where applicable, further processed by modulators 254a to 254r (e.g., for Discrete Fourier Transform Extended OFDM (DFT-s-OFDM), CP-OFDM, etc.), and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 254, detected by MIMO detector 236 (where applicable), and further processed by receiving processor 238 to obtain decoded data and control information transmitted by UE 120. The receiver processor 238 can provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicates with the core network 130 via the communication unit 244. The core network 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0053] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2Any other components may perform one or more techniques associated with CSI reporting, as described in more detail elsewhere. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or instruct, for example Figure 8 and Figure 10 The operation of the process and / or other processes as described. Memory 242 and memory 282 may store data and program code for base station 110 and UE 120, respectively. Scheduler 246 may schedule UEs for data transmission on downlink and / or uplink.

[0054] In some aspects, UE 120 and / or base station 110 may include components for receiving and components for transmitting. Such components may include combinations of... Figure 2 The UE 120 or one or more components of the base station 110 described.

[0055] As indicated above, Figure 2 This is provided merely as an example. Other examples are available in conjunction with [the relevant documentation / information]. Figure 2 The examples described are different.

[0056] The deployment of communication systems (such as 5G New Radio (NR) systems) can involve various components or parts arranged in multiple ways. In a 5G NR system or network, network nodes, network entities, network mobility elements, radio access network (RAN) nodes, core network nodes, network elements or network equipment (such as base stations (BS)), or one or more units (or components) performing base station functionality can be implemented in aggregated or decomposed architectures. For example, BSs (such as Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), transmit and receive point (TRP), or cell, etc.) can be implemented as aggregated base stations (also known as standalone BS or monolithic BS) or decomposed base stations.

[0057] Aggregated base stations can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. Decentralized base stations can be configured to utilize a protocol stack that is physically or logically distributed across two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs) (i.e., central or distributed units). In some aspects, the CU may be implemented within a RAN node, and one or more DUs may co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other RAN nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit (e.g., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU)).

[0058] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in Integrated Access Backhaul (IAB) networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)). Decomposition can include distributing functionality across two or more units in various physical locations, as well as virtually distributing the functionality of at least one unit, which enables flexibility in network design. The various units in a decomposed base station or decomposed RAN architecture can be configured for wired or wireless communication with at least one other unit.

[0059] In some cases, different types of devices supporting different types of applications and / or services can coexist in a cell. Examples of different types of devices include UE handsets, Customer Premises Equipment (CPE), vehicles, Internet of Things (IoT) devices, etc. Examples of different types of applications include Ultra Reliable Low Latency Communication (URLLC) applications, Massive Machine-Type Communication (mMTC) applications, Enhanced Mobile Broadband (eMBB) applications, Vehicle-to-Everything (V2X) applications, etc. Furthermore, in some cases, a single device can simultaneously support different applications or services.

[0060] Figure 3A diagram illustrating an example of a decomposed base station 300 architecture is shown. The decomposed base station 300 architecture may include one or more central units (CUs) 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more decomposed base station units, such as a near real-time (near-RT) RAN Intelligent Controller (RIC) 325 via an E2 link, or a non-real-time (non-RT) RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both. CUs 310 may communicate with one or more distributed units (DUs) 330 via appropriate midhaul links (such as F1 interfaces). DUs 330 may communicate with one or more radio units (RUs) 340 via appropriate fronthaul links. RUs 340 may communicate with corresponding UEs 120 via one or more radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0061] Each of these units (e.g., CU 310, DU 330, RU 340, and near-RT RIC 325, non-RT RIC 315, and SMO frame 305) may include one or more interfaces, or may be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of these units, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally, these units may include wireless interfaces that may include receivers, transmitters, or transceivers (such as radio frequency (RF) transceivers) configured to receive signals or transmit signals to one or more other units via wireless transmission media, or both.

[0062] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP)), control plane functions (e.g., Central Unit-Control Plane (CU-CP)), or combinations thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling, as needed.

[0063] DU 330 may correspond to a logic unit that includes one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, DU 330 may, at least in part, host one or more of the Radio Link Control (RLC) layer, the Media Access Control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) depending on functional splits (such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 330 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signaling with other layers (and modules) hosted by DU 330 or with control functions hosted by CU 310.

[0064] Lower-layer functionality can be implemented by one or more RU 340s. In some deployments, an RU340 controlled by a DU 330 may correspond to a logical node that hosts RF processing functions or low-PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, or both, based at least in part on functional decomposition (such as lower-layer functional decomposition). In this architecture, the RU 340 may be implemented to handle over-the-air (OTA) communications with one or more UE 120s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration enables the implementation of the DU 330 and CU 310 in a cloud-based RAN architecture (such as a vRAN architecture).

[0065] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform such as the Open Cloud (O-cloud) 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, and near-RT RIC 325. In some implementations, the SMO framework 305 can communicate with the hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with one or more RU 340s via the O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0066] The non-RT RIC 315 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including AI / ML workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface such as an E2 interface that connects one or more CU 310s, one or more DU 330s, or both, and an O-eNB 311 to the near-RT RIC 325.

[0067] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via O1) or via the creation of RAN management policies (such as A1 policies).

[0068] Data can be collected from user equipment (UE) for model training on the UE side or chipset vendor side. Data can also be collected for network-side artificial intelligence or machine learning (ML) models. In some respects, these models can be beam management specific. Reports from the UE should take into account overhead, UE complexity, and power consumption.

[0069] Data collection for AI / ML models at the base station (e.g., gNB) may specify more complex Layer 1 (L1) Reference Signal Received Power (RSRP) feedback (more generally referred to as Channel State Information (CSI) reports or “special” CSI reports) for base station-side beam prediction. More complex reporting may be undesirable for the UE due to increased UE power consumption. Additionally, more complex L1-RSRP feedback may include a large number of beams or more stringent L1-RSRP measurement accuracy requirements. For example, a standard CSI report may include up to four reported beams. The UE may stop measuring beams predicted to be weak to reduce power consumption at the UE for beam measurement. However, the base station may still be interested in weak beams used for data collection or base station-side time-domain beam prediction. Therefore, in such cases, the UE may consume additional power.

[0070] Furthermore, in order to train AI / ML models with good predictive performance (e.g., accurate prediction) at the base station or to perform base station-side beam prediction, the accuracy of L1-RSRP measurements used for data collection may be greater than that used for routine purposes. To meet such requirements, the UE may need to use more antenna elements or open additional panels, which may result in higher power consumption.

[0071] According to various aspects of this disclosure, the UE may decide whether to provide more complex CSI feedback requested by the base station. Depending on the UE's willingness to assist network-side data collection and / or network-side beam prediction, when requested by the network to provide a more complex CSI report, the UE may indicate whether it will provide such a report. This indication may be transmitted via static radio resource control (RRC) signaling (e.g., via UE capability reporting). In other aspects, the indication may be sent on demand or in response to event triggering. The UE's willingness to provide a more complex report to the base station may depend on certain conditions, such as the UE's computational complexity and / or power budget.

[0072] Figure 4 This is a timeline illustrating specific Channel State Information (CSI) reports according to various aspects of this disclosure. Network-requested CSI reports can be used for data collection or AI / ML inference. Figure 4 In the example, base station (e.g., gNB) 110 communicates with UE 120. At a first time 402, base station 110 requests the UE to provide feedback on the L1-RSRP / SINR (signal-plus-noise-interference ratio) measurement associated with a specific beam (e.g., a synchronization block (SSB) or channel state information reference signal (CSI-RS)) within a first set of beams used for the first CSI report. The first CSI report is more complex than the second CSI report, which includes L1-RSRP / SINR measurements associated with selective beams (e.g., SSB / CSI-RS) within a second set of beams (e.g., SSB / CSI-RS). The first report may also be referred to as a special CSI report or a complex CSI report.

[0073] exist Figure 4 In the example, UE 120 decides that it will provide this feedback to base station 110 regarding the first CSI report. Figure 4 In other examples not shown in the example, UE 120 may decide that it will not provide this kind of feedback for the first CSI report.

[0074] If the UE decides to provide such feedback in the first CSI report, at time 404, the UE 120 indicates this decision to the base station 110. At times 406 and 408, the UE 120 receives from the base station 110 the scheduling information for activating the first CSI report and the corresponding SSB / CSI-RS for transmission of the first CSI report. If the UE 120 decides not to provide the requested feedback (not shown), then the UE 120 is not expected to be scheduled to have a first CSI report. At time 410, the UE 120 transmits the first CSI report to the base station 110 based on the scheduling at time 406.

[0075] According to various aspects of this disclosure, special or more complex reports are defined based on certain criteria. A first criterion for determining whether a report is complex (or special) is a higher number of L1-RSRP / SINR measurements associated with more SSB / CSI-RS in a single CSI reporting time. This criterion may be further based on the first CSI report including at least one more L1-RSRP / SINR measurement than the second CSI report for each CSI reporting time. For example, the second CSI report may include up to X measurements per CSI reporting time, such as four L1-RSRP / SINR measurements per CSI reporting time. The value of X may be predefined in a standard network configuration instruction in a request for the first CSI report, or reported by the UE in a response to the request. In some aspects, the first CSI report and the second CSI report may be referred to as R19+ and “legacy” L1-RSRP / SINR reports, respectively. In other aspects, the first CSI report may be referred to as an L1-RSRP / SINR report used for network-side data collection or beam prediction.

[0076] This standard may further depend on whether the number of candidate SSBs / CSI-RSs associated with the first CSI report exceeds a certain threshold number Y. CSI reports associated with fewer than Y SSBs / CSI-RS are considered second CSI reports. The value of Y may be predefined in the standard base station configuration instruction in the request for the first CSI report, or reported by the UE in the response to the request.

[0077] Figure 5 This is a block diagram illustrating various aspects of legacy and special Channel State Information (CSI) reporting according to this disclosure. Figure 5 In this example, the first report 502 is classified as a more complex or special report. The first report 502 includes twenty candidate beams (or SSB / CSI-RS) 504. Therefore, Y=20. Among the twenty candidate beams 504, measurements are requested for five beams 506. Therefore, X=5. In this example, a report is considered complex if Y>15 and X≤4. Therefore, in this example, the first report 502 is complex.

[0078] The second report 510 includes twenty candidate beams (or SSB / CSI-RS) 514. Therefore, Y=20. Among the twenty candidate beams 514, measurements of three beams 516 are requested. Therefore, X=3. In this example, the report is considered complex if Y>15 and X≤4. Therefore, in this example, the second report 510 is uncomplex.

[0079] The third report 520 includes ten candidate beams (or SSB / CSI-RS) 524. Therefore, Y=10. Measurements are requested for eight beams 526 out of the ten candidate beams 524. Therefore, X=8. In this example, the report is considered complex if Y>15 and X≤4. Therefore, in this example, the third report 520 is uncomplex.

[0080] The second criterion used to determine whether a report is special or complex relates to the accuracy requirements of the report. The reported L1-RSRP / SINR measurements should meet the more stringent accuracy requirements for special or complex reports. This criterion may be further based on multiple candidate accuracy requirement levels. In some respects, the accuracy requirement level is relative to the second CSI report. For the first CSI report, multiple accuracy levels may exist. These levels may be predefined, and optionally, the accuracy level required by the base station is signaled in the network request for the first CSI report. The accuracy level that the UE is willing to support is reported in the UE willingness response feedback. For example, the UE may report the supported accuracy requirement level identifier (ID) Z. In some respects, the accuracy requirement level ID is indexed in ascending order of accuracy level. The UE supports accuracy level ID ≤ Z.

[0081] Figure 6 This is a block diagram illustrating the accuracy levels of specific Channel State Information (CSI) reports according to various aspects of this disclosure. Figure 6 In the example, ten accuracy levels (0 to 9) are defined (602), and the network (e.g., gNB) requests eight accuracy levels (0 to 7) for special or complex reports (604). In this example, the UE indicates support for accuracy level 3 in message 606. Therefore, the UE supports accuracy levels 0, 1, 2, and 3 (608).

[0082] The signaling carrying network requests for specific L1-RSRP / SINR feedback is now discussed. The network may request the first CSI report via at least one of the following signaling schemes: System Information, RRC Configuration, and Media Access Control-Control Element (MAC-CE).

[0083] When using system information, the network broadcasts in its system information associated with a cell an indication that it wants to obtain complex or special CSI reports from UEs accessing or already served by that cell. The UE can use its UE capability report to respond to the indication in the system information. For example, the UE can indicate whether it will provide a first CSI report during the initial access procedure via its UE capability report. In other respects, the UE indicates via RRC signaling, MAC-CE, or uplink control information (UCI) that it will provide a first CSI report in its capability report after completing initial access.

[0084] If RRC configuration is used, the network can configure itself to request the first CSI report from the UE via RRC signaling. This configuration can be performed at the serving cell level, allowing different serving cells to have different preferences. The UE can respond to the request by indicating its intention via RRC signaling, MAC-CE, or UCI. If the network request for the first CSI report is configured per serving cell, this UE feedback can be tailored to different serving cells.

[0085] If MAC-CE is used, the network can indicate to the UE that it wants to obtain the first CSI report. The MAC-CE indication can be associated with the serving cell that transmitted the request. Alternatively, the MAC-CE can include the serving cell ID associated with the request. The UE can respond to the request indicating its intention via MAC-CE or UCI. If the network request for the first CSI report is associated with multiple serving cells, this UE response can be directed to different serving cells.

[0086] In some aspects of this disclosure, the network explicitly indicates the purpose of the first CSI report. Utilizing system information, RRC configuration, and a MAC-CE request for a complex or special report, the network may explicitly indicate the purpose of the requested first CSI report. Non-limiting examples of purposes include data collection for network-side AI / ML model training, AI / ML model inference, or network-side beam prediction. For example, a UE might be more willing to participate in a complex report because network-side beam prediction can improve communication with the UE. Another example of a special CSI report purpose is the scheduling of the Physical Downlink Shared Channel (PDSCH) or Physical Downlink Control Channel (PDCCH). For example, a UE might benefit from more flexible PDSCH / PDCCH scheduling in situations where a preferred beam receives high-level interference from other UEs or cells. The trade-off for flexible scheduling is the cost of more complex L1-RSRP / SINR measurements. In these aspects, the UE decides whether to support the network-requested first CSI report based on the purpose indicated by the network.

[0087] The UE response feedback signaling is now described. In some aspects, the UE may utilize UE capability signaling during the initial access procedure to respond to network requests for complex or special reports. In other aspects, the UE sends response feedback via RRC signaling, MAC-CE, or UCI. In capability reports, RRC signaling, MAC-CE, and UCI, the UE may report values ​​X (the number of measurements supported per CSI reporting time), Y (the number of supported candidate beams (e.g., CSI-RS / SSB)), and / or Z (the supported accuracy level). In specific implementations of UE capability reports, RRC, MAC-CE, and UCI, a UE that does not report such capabilities is considered to be unwilling to provide the first CSI report. In specific implementations of RRC, MAC-CE, and UCI, a network that does not receive RRC / MAC-CE / UCI messages is also considered to be unwilling to provide the first CSI report. UE willingness feedback based on RRC / MAC-CE / UCI can overwrite previous UE willingness feedback sent via UE capability reports during the initial access procedure. In addition to system information requests, overwriting can occur regardless of whether the network sends network requests based on RRC / MAC-CE / UCI.

[0088] As indicated above, Figures 3 to 6 This is provided as an example. Other examples are available relative to... Figures 3 to 6 The examples described are different.

[0089] Figure 7 This is a block diagram illustrating an example wireless communication device that supports special Channel State Information (CSI) feedback reporting for network requests according to various aspects of this disclosure. Wireless communication device 700 may be as shown in the reference... Figure 1 , Figure 2 and Figure 4 Examples of various aspects of the described UE 120. The wireless communication device 700 may include a receiver 710, a transmitter 720, a communication manager 705, a first-type CSI request component 730, a first-type CSI report configuration component 740, and a first-type CSI report component 750, which can communicate with each other (e.g., via one or more buses). In some examples, the wireless communication device 700 is configured to perform operations including the following references. Figure 8 The described process is the operation of 800.

[0090] In some examples, the wireless communication device 700 may include a chip, system-on-a-chip (SOC), chipset, package, or device, the device including at least one processor and at least one modem (e.g., a 5G modem or other cellular modem). In some examples, the communication manager 705 or its sub-components may be separate and distinct components. In some examples, at least some components of the communication manager 705 are at least partially implemented as software stored in memory. For example, portions of one or more components of the communication manager 705 may be implemented as non-transitory code executable by a processor to perform the function or operation of the respective component.

[0091] Receiver 710 may receive, via various channels including control channels (e.g., Physical Downlink Control Channel (PDCCH), Physical Uplink Control Channel (PUCCH), or Physical Sidelink Control Channel (PSCCH)) and data channels (e.g., Physical Downlink Shared Channel (PDSCH), Physical Sidelink Shared Channel (PSSCH), Physical Uplink Shared Channel (PUSCH)), one or more of the following from one or more other wireless communication devices: reference signals (e.g., periodically configured Channel State Information Reference Signal (CSI-RS), aperiodically configured CSI-RS, or multi-beam specific reference signals), synchronization signals (e.g., synchronization signal blocks (SSBs)), control information, and data information (such as in packet form). Other wireless communication devices may include, but are not limited to, reference signals... Figure 1 and Figure 2 The described base station 110 or as referenced Figure 3 The CU 310, DU 330, or RU 340 described.

[0092] The received information can be transmitted to other components of device 700. Receiver 710 can be a reference. Figure 2 Examples of various aspects of the described receiver processor 256. Receiver 710 may include or otherwise utilize an antenna set (e.g., the antenna set may be a reference antenna set). Figure 2 Examples of various aspects of the described antenna 252 are examples of a radio frequency (RF) chain set.

[0093] Transmitter 720 can transmit signals generated by communication manager 705 or other components of wireless communication device 700. In some examples, transmitter 720 may be co-located with receiver 710 in a transceiver module. Transmitter 720 may be a reference Figure 2 Examples of various aspects of the described transmitting processor 266. Transmitter 720 may be coupled to or otherwise utilize an antenna array (e.g., the antenna array may be a reference antenna array). Figure 2Examples of various aspects of the described antenna 252), the antenna assembly may be antenna elements shared with the receiver 710. In some examples, the transmitter 720 is configured to transmit control information in the PUCCH, PSCCH, or PDCCH and data in the PUSCH, PSSCH, or PDSCH.

[0094] Communication Manager 705 can be used as a reference. Figure 2 Examples of various aspects of the described controller / processor 280. The communication manager 705 includes a first-type CSI request component 730, a first-type CSI report configuration component 740, and a first-type CSI report component 750. In some examples, working in conjunction with receiver 710, the first-type CSI request component 730 can receive requests from the network for first-type Channel State Information (CSI) reports, which include the number of Reference Signal Received Power (RSRP) values ​​and / or Signal-to-Interference-Noise Ratio (SINR) values ​​greater than a first threshold level at a single CSI report time, and / or the first-type CSI reports are associated with accuracy requirements greater than a second threshold level.

[0095] In some other examples, cooperating with transmitter 720, first-type CSI request component 730 may, in response to the request, send a message indicating whether the UE will provide a CSI report. Additionally, cooperating with receiver 710, first-type CSI report configuration component 740 may, in response to the message indicating that the UE will provide a CSI report, receive scheduling information from the network for the transmission of the CSI report, and may, in response to the message indicating that the UE will provide a CSI report, receive signals associated with the CSI report from the network. Finally, cooperating with transmitter 720, first-type CSI report component 750 may, according to the scheduling information, send a CSI report for the signals associated with the CSI report.

[0096] Figure 8 This is a flowchart illustrating, for example, an example process 800 performed by a user equipment (UE) according to various aspects of this disclosure. Example process 800 is an example of a user equipment (UE) responding to a network request for a special channel state information (CSI) feedback report for purposes such as machine learning. Operation of process 800 can be implemented by UE 120.

[0097] At box 802, the user equipment (UE) receives a request from the network for a first type of Channel State Information (CSI) report. The first type of CSI report includes the number of Reference Signal Received Power (RSRP) values ​​and / or Signal-to-Interference-Noise Ratio (SINR) values ​​greater than a first threshold level in a single CSI reporting time, and / or the first type of CSI report is associated with an accuracy requirement greater than a second threshold level. For example, the UE (e.g., using antenna 252, DEMOD / MOD 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282, etc.) may receive this request. In some aspects, the first type of CSI report is associated with the number of Synchronization Signal Blocks (SSBs) and / or Channel State Information Reference Signals (CSI-RS) greater than a third threshold level in a single CSI reporting time.

[0098] At box 804, in response to the request, the User Equipment (UE) sends a message indicating whether the UE will provide a CSI report. For example, the UE (e.g., using antenna 252, DEMOD / MOD 254, TX MIMO processor 266, transmit processor 264, controller / processor 280, memory 282, etc.) may send this message. In some aspects, the request is received via system information, and the message is sent in the UE capability report during the initial access procedure. The UE capability report may indicate the number of RSRP and / or SINR values ​​supported for the CSI report, the number of supported Synchronization Signal Blocks (SSBs) and / or Channel State Information Reference Signals (CSI-RS), and / or the supported accuracy level. In other aspects, after the initial access procedure is completed, the request is received via system information, and the message is sent in a Radio Resource Control (RRC) message, a Medium Access Control-Control Element (MAC-CE), or an Uplink Control Information (UCI). In other respects, the request is received via serving cell-level Radio Resource Control (RRC) signaling, and the message is sent to different serving cells in an RRC message, a Medium Access Control-Control Element (MAC-CE), or an Uplink Control Information (UCI). In other respects, the request is received via a first serving cell-level Medium Access Control-Control Element (MAC-CE), and the message is sent to different serving cells in a second MAC-CE or an Uplink Control Information (UCI). The request may indicate the purpose of the CSI report, and the message may indicate whether the UE will provide a CSI report at least in part for that purpose. The message may be sent in a Radio Resource Control (RRC) message, a Medium Access Control-Control Element (MAC-CE), or an Uplink Control Information (UCI), and the message indicates the number of RSRP values ​​and / or SINR values ​​supported for the CSI report, the number of supported Synchronization Signal Blocks (SSBs) and / or Channel State Information Reference Signals (CSI-RS), and / or the supported accuracy level. Messages sent in RRC messages, MAC-CE, or UCI can overwrite previously transmitted UE capability reports in response to the request.
