Association and mapping between beam sets

Abstract

Aspects of the present disclosure relate to a UE, a processor for wireless communication, a network entity, a method, and a computer readable medium for association and mapping between beam sets. The UE receives a CSI report configuration corresponding to a first set of beams and associated with a CSI resource configuration, and indication information indicating a second set of beams associated with the CSI resource configuration. The UE also receives a CSI RS or SSB for the second set of beams based on the CSI resource configuration and the indication information. The UE transmits a beam report for the first set of beams. In this way, the effective pattern of the measurement beam set, the report beam set, and the measurement beam set between the network and the UE may be aligned in a simple and effective manner.

Description

Technical Field

[0001] This disclosure relates to wireless communications, and more specifically to user equipment (UE), network entities, processors and methods for wireless communications, and computer-readable media for association and mapping between beam sets. Background Technology

[0002] A wireless communication system may include one or more network communication devices, such as base stations, which may also be referred to as eNodeBs (eNBs), next-generation NodeBs (gNBs), or other suitable terms. Each network communication device (such as a base station) may support wireless communication for one or more user communication devices, which may also be referred to as user equipment (UEs), or other suitable terms. The wireless communication system may support wireless communication with one or more user communication devices by utilizing the resources of the wireless communication system (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)). Additionally, the wireless communication system may also support wireless communication across various radio access technologies, including third-generation (3G) radio access technology, fourth-generation (4G) radio access technology, fifth-generation (5G) radio access technology, and other suitable radio access technologies after 5G (e.g., sixth-generation (6G)).

[0003] Artificial intelligence or machine learning (AI / ML) for beam management in terms of spatial beam prediction (BM-case1) and temporal beam prediction (BM-case2) has been discussed in the 3GPP working groups. AI / ML for beam management can be categorized into two types based on which side the AI / ML model is deployed: network (NW)-side AI / ML models and UE-side AI / ML models. In AI / ML-based beam management, a beam set (set B) is measured, and the measurement results are then fed into an AI / ML model that predicts another beam set (set A), where set B can be a subset of set A or different from set A. Lifecycle management (LCM) manages the AI / ML model throughout its lifecycle, and it is performed based on either function or model. Regardless of whether the LCM of the AI / ML model is function-based or model-based, multiple AI / ML models with different combinations of sets A and B can be supported at the UE side for AI / ML models. The use of multiple AI / ML models can be controlled by the UE. In other aspects, the variable set B pattern can be supported by AI / ML models for model generalization in different scenarios. Therefore, the understanding of efficient combinations of sets B and A, as well as efficient set B patterns, should be aligned with NW and UE. Summary of the Invention

[0040] The principles of this disclosure will now be described with reference to some embodiments. It should be understood that these embodiments are described for illustrative purposes only and to assist those skilled in the art in understanding and implementing this disclosure, and do not imply any limitation on the scope of this disclosure. The disclosure described herein can be implemented in various ways other than those described below. In the following description and claims, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0041] References to "an embodiment," "example embodiment," "embodiment," "some embodiments," etc., in this disclosure indicate that the embodiments(s) described may include a particular feature, structure, or characteristic, but not every embodiment necessarily must include that particular feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same(s) embodiments(s). Moreover, when a particular feature, structure, or characteristic is described in connection with an embodiment, those skilled in the art will recognize that in conjunction with other embodiments (whether explicitly described or not) such a feature, structure, or characteristic may affect such a feature, structure, or characteristic within the scope of their knowledge.

[0042] It should be understood that although the terms “first” and “second” may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, a first element may also be referred to as a second element without departing from the scope of the embodiments, and similarly, a second element may also 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. In some examples, values, processes, or apparatus are referred to as “best,” “lowest,” “highest,” “minimum,” “maximum,” etc. It should be understood that such descriptions are intended to indicate that selection can be made from a number of functional alternatives used, and that these selections are not necessarily better, smaller, higher, or otherwise preferred than other selections.

[0043] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the embodiments. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” used herein are also intended to include the plural forms. Furthermore, it should be understood that the terms “comprising,” “including,” “having,” “comprising,” and / or “containing,” when used herein, specify the presence of said features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof. For example, the term “comprising” and variations thereof should be understood as open terms meaning “including, but not limited to.” The term “based on” should be understood as “at least partially based on.” The terms “one embodiment” and “embodiment” should be understood as “at least one embodiment.” The term “another embodiment” should be understood as “at least one other embodiment.” The use of expressions such as “A and / or B” can mean “A only” or “B only” or “both A and B.” Other explicit and implicit definitions may be included below.

[0044] AI / ML models used for beam management are categorized into two types based on which side they are deployed on: NW-side AI / ML models and UE-side AI / ML models. In AI / ML-based beam management, a beam set (set B) is measured, and the measurement results are then fed into an AI / ML model that predicts another beam set (set A), where set B is a subset of set A, or different from set A. For UE-side AI / ML models, multiple AI / ML models with different combinations of sets A and B can be supported at the UE. The use of multiple AI / ML models can be controlled by the UE. In other aspects, variable set B patterns can be supported by AI / ML models for model generalization in different scenarios. Therefore, the understanding of effective combinations of sets B and A, and effective set B patterns, should be aligned between the NW and UE.

[0045] Note that in this disclosure, the term "set B" refers to the set of beams measured at the UE or NW, while the term "set A" refers to the set of beams used for beam management based on measurement predictions and reports from set B, for example, by using AI / ML. Set B may be a subset of set A, or may be different from set A. Also note that each beam in set B can be configured via either the Channel State Information Reference Signal (CSI-RS) resource or the Synchronization Signal / Physical Broadcast Channel (SSB) resource.

[0046] A solution is proposed to address the aforementioned issues. According to embodiments of this disclosure, a UE can receive a channel state information (CSI) report configuration for beam reports used for AI model inference output, wherein the CSI report configuration is linked to a CSI resource configuration for at least one first beam set, and a second beam set is associated with the CSI report configuration via indication information.

[0047] In some embodiments, indication information may be included in a Radio Resource Control (RRC) (re)configuration used to link a CSI reporting configuration or CSI resource configuration for a first beam set to a second beam set. The CSI resource configuration may reuse legacy Rel-17 CSI resource settings. CSI-ResourceConfig The CSI resource configuration associated with the CSI reporting configuration for the first beam set (set A) may include a non-zero power (NZP) CSI-RS resource set used for beam measurements of a second beam set (set B) with variable beam patterns. Additionally, another indication should be sent to the UE to identify the beams within the second beam set. This indication should include resource indicators for N CSI-RS resources in the CSI-RS resource set, N Transmission Control Indicator (TCI) status IDs for the N CSI-RS resources, and N Tx beam identifiers corresponding to the N CSI-RS resources, enabling the UE to have knowledge of the actual CSI-RS resources to be transmitted, the Tx beams of each CSI-RS resource, and the corresponding Rx beams. Alternatively, the CSI resource configuration associated with the CSI reporting configuration for the first beam set (set A) may contain Y>=1 NZP CSI-RS resource sets, which correspondingly correspond to Y possible second beam sets to be measured (set B), and one of the Y beam sets used for beam measurement may also be indicated by NW. After AI / ML model inference, the prediction results may be reported via CRIs corresponding to the identifiers of the top K predicted beams or the top K predicted beams within the first beam set.

[0048] In some embodiments, the indication information can indicate CSI-RS resources for a second beam set based on the CSI resource configuration for a first beam set. A new CSI-RS resource set can be introduced to enable a more flexible CSI-RS resource configuration for beam measurement. The new CSI-RS resource set may contain two parts regarding CSI-RS resources: one part defines a list of basic parameters for the CSI-RS resources, and the other part defines a list of resource mappings for the CSI-RS resources. The former is used for the larger beam set, while the latter is used for a smaller beam set, which may be a subset of the larger beam set. In this case, CSI-RS resources for the second beam set (set B) can be selected from the CSI resource configuration for the first beam set and indicated to the UE via Media Access Control (MAC) Control Element (MAC CE) signaling. Assuming the CSI-RS resource set is configured for the first beam set, a subset of the CSI-RS resources in the CSI-RS resource set will be indicated to the UE, and the UE should assume that CSI-RS is transmitted only using the indicated resources. The CSI-RS resource set is defined by the new CSI-RS resource set described above. After AI / ML model inference, the UE will report the prediction results in the beam report corresponding to the CSI report configuration, including the CRI corresponding to the first K beams of the prediction.

[0049] In some embodiments, after AI / ML model inference, the UE will report the predicted Layer 1 reference signal received power (L1-RSRP) corresponding to the first K predicted beams.

[0050] Note that the Tx beam is represented by a CSI-RS resource or SSB resource used for beam management and corresponds in this disclosure to a downlink spatial domain transmission filter for a base station (e.g., gNB); and the Rx beam corresponds to a downlink spatial domain reception filter, which can be indicated by quasi-co-location (QCL) information contained in the TCI state.

[0051] The aspects of this disclosure are described in the context of wireless communication systems. Figure 1Examples of wireless communication systems 100 that may be implemented in some embodiments of this disclosure are shown. Wireless communication system 100 may include one or more network entities 102 (also referred to as network devices (NEs)), one or more UEs 104, a core network 106, and a packet data network 108. Wireless communication system 100 may support various radio access technologies. In some implementations, wireless communication system 100 may be a 4G network, such as an LTE network or an advanced LTE (LTE-A) network. In some other implementations, wireless communication system 100 may be a 5G network, such as an NR network. In other implementations, wireless communication system 100 may be a combination of 4G and 5G networks, or other suitable radio access technologies, including IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20. Wireless communication system 100 may support radio access technologies beyond 5G. Additionally, wireless communication system 100 may support technologies such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), or Code Division Multiple Access (CDMA).

[0052] One or more network entities 102 may be distributed across a geographical area to form a wireless communication system 100. One or more network entities among the network entities 102 described herein may be, include, or may be referred to as network nodes, base stations, network elements, radio access networks (RAN), base transceiver stations, access points, NodeBs, eNodeBs (eNBs), next-generation NodeBs (gNBs), or other suitable terms. Network entities 102 and UE 104 may communicate via communication link 110, which may be a wireless or wired connection. For example, network entities 102 and UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) via a Uu interface. In a 3GPP non-terrestrial network (NTN), network entity 102 in satellite form may communicate directly with UE 104 using an NR / LTE Uu interface. This satellite may be a transparent satellite or a regenerated satellite. For an NTN with a transparent satellite, a terrestrial base station may communicate with the UE via the satellite. For an NTN with a regenerated satellite, the base station may be located on the satellite and communicate directly with the UE.

[0053] Network entity 102 may provide a geographic coverage area 112 for which it may support services (e.g., voice, video, packet data, messaging, broadcasting, etc.) for one or more UEs 104 within the geographic coverage area 112. For example, network entity 102 and UE 104 may support wireless communication of signals associated with services (e.g., voice, video, packet data, messaging, broadcasting, etc.) based on one or more radio access technologies. In some implementations, network entity 102 may be mobile, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but different geographic coverage areas 112 may be associated with different network entities 102. The information and signals described herein may be represented using a variety of different techniques and methods. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be mentioned in the description may be represented by voltage, current, electromagnetic waves, magnetic fields or particles, light fields or particles, or any combination thereof.

[0054] One or more UEs 104 may be distributed across a geographical area of ​​the wireless communication system 100. UE 104 may include or be referred to as a mobile device, wireless device, remote device, remote unit, handheld device, or subscriber device, or some other suitable term. In some implementations, UE 104 may be referred to as a unit, station, terminal, or client, among other examples. Alternatively or additionally, UE 104 may be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine Type Communication (MTC) device, among other examples. In some implementations, UE 104 may be stationary within the wireless communication system 100. In some other implementations, UE 104 may be mobile within the wireless communication system 100.

[0055] One or more UEs 104 can be devices of different forms or with different capabilities. Some examples of UEs 104 are shown in... Figure 1 It is shown in the middle. For example... Figure 1 As shown, UE 104 can communicate with various types of devices, such as network entity 102, other UE 104, or network devices (e.g., core network 106, packet data network 108, relay devices, integrated access and backhaul (IAB) nodes, or another network device). Alternatively or additionally, UE 104 can support communication with other network entities 102 or UE 104, which can act as relays in the wireless communication system 100.

[0056] UE 104 can also support direct wireless communication with other UE 104s via communication link 114. For example, UE 104 can support direct wireless communication with another UE 104 via a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular V2X deployments, communication link 114 may be referred to as a side link. For example, UE 104 can support direct wireless communication with another UE 104 via a PC5 interface.

[0057] Network entity 102 may support communication with core network 106, or with another network entity 102, or both. For example, network entity 102 may interface with core network 106 via one or more backhaul links 116 (e.g., via S1, N2, N2, or another network interface). Network entities 102 may communicate with each other via backhaul links 116 (e.g., via X2, Xn, or another network interface). In some implementations, network entities 102 may communicate directly with each other (e.g., between network entities 102). In some other implementations, network entities 102 may communicate with each other or indirectly (e.g., via core network 106). In some implementations, one or more network entities 102 may include sub-components, such as access network entities, which may be an example of an access node controller (ANC). The ANC may communicate with one or more UEs 104 via one or more other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmit-receive points (TRPs).

[0058] In some implementations, network entity 102 can be configured in a decomposed architecture that can utilize a protocol stack physically or logically distributed across two or more network entities 102, such as an Integrated Access Backhaul (IAB) network, an Open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 102 may include one or more of the following: a Central Unit (CU), a Distributed Unit (DU), a Radio Unit (RU), a RAN Intelligent Controller (RIC) (e.g., a Near-RT RIC, a Non-RT RIC), a Service Management and Orchestration (SMO) system, or any combination thereof.

[0059] An RU can also be referred to as a radio head, intelligent radio head, remote radio head (RRH), remote radio unit (RRU), or transmit-receive point (TRP). One or more components of network entity 102 in the decomposed RAN architecture can be co-located, or one or more components of network entity 102 can be located in distributed locations (e.g., separate physical locations). In some implementations, one or more network entities 102 in the decomposed RAN architecture can be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0060] The functional division among CU, DU, and RU can be flexible and can support different functions depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combination thereof) are performed at the CU, DU, or RU. For example, the functional division of the protocol stack can be adopted between the CU and DU, such that the CU can support one or more layers of the protocol stack, while the DU can support one or more different layers of the protocol stack. In some implementations, the CU can host upper-layer protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functions and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU can connect to one or more DUs or RUs, and one or more DUs or RUs can host lower-layer protocol layer functions and signaling, such as Layer 1 (L1) (e.g., Physical Layer (PHY)) or L2 (e.g., Radio Link Control (RLC), Media Access Control (MAC)) functions, and each can be at least partially controlled by the CU 160.

[0061] Alternatively, or alternatively, the functional division of the protocol stack can be adopted between DU and RU, such that DU can support one or more layers of the protocol stack, while RU can support one or more different layers of the protocol stack. DU can support one or more different cells (e.g., via one or more RUs). In some implementations, the functional division between CU and DU or between DU and RU can be within the protocol layer (e.g., some functions for the protocol layer can be performed by one of CU, DU, or RU, while other functions of the protocol layer are performed by a different one of CU, DU, or RU).

[0062] The CU can be further functionally divided into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU can connect to one or more DUs via mid-range communication links (e.g., F1, F1c, F1-u), while the DUs can connect to one or more RUs via front-end communication links (e.g., open front-end (FH) interfaces). In some implementations, the mid-range or front-end communication links can be implemented based on interfaces (e.g., channels) between layers of a protocol stack, supported by corresponding network entities 102 communicating via such communication links.

[0063] Core network 106 can support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. Core network 106 can be an evolved packet core (EPC) or a 5G core network (5GC), which may include control plane entities that manage access and mobility (e.g., Mobility Management Entity (MME), Access and Mobility Management Functions (AMF)) and user plane entities that route or interconnect packets to external networks (e.g., Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Functions (UPF)). In some implementations, the control plane entities may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management (e.g., data bearers, signaling bearers, etc.) for one or more UEs 104 served by one or more network entities 102 associated with core network 106.

[0064] Core network 106 can communicate with packet data network 108 via one or more backhaul links 116 (e.g., via S1, N2, N2, or another network interface). Packet data network 108 may include application server 118. In some implementations, one or more UEs 104 may communicate with application server 118. UE 104 may establish a session (e.g., Protocol Data Unit (PDU) session, etc.) with core network 106 via network entity 102. Core network 106 can use the established session (e.g., established PDU session) to route traffic (e.g., control information, data, etc.) between UE 104 and application server 118. A PDU session may be one example of a logical connection between UE 104 and core network 106 (e.g., one or more network functions of core network 106).

[0065] In the wireless communication system 100, network entity 102 and UE 104 can use the resources of the wireless communication system 100 (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communication). In some implementations, network entity 102 and UE 104 can support different resource structures. For example, network entity 102 and UE 104 can support different frame structures. In some implementations, such as in 4G, network entity 102 and UE 104 can support a single frame structure. In some other implementations, such as in 5G and other suitable radio access technologies, network entity 102 and UE 104 can support various frame structures (i.e., multiple frame structures). Network entity 102 and UE 104 can support various frame structures based on one or more digital technologies.

[0066] One or more digital technologies may be supported in the wireless communication system 100, and the digital technologies may include subcarrier spacing and cyclic prefix. The first digital technology (e.g., μ =0) can be associated with the first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first digital technique (e.g., ...) associated with the first subcarrier spacing (e.g., 15 kHz) is... μ =0) can utilize one time slot per subframe. Second digital technologies (e.g., μ =1) can be associated with the second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. The third digital technology (e.g., μ =2) can be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth digital technology (e.g., μ =3) can be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth digital technology (e.g., μ =4) can be associated with the fifth subcarrier spacing (e.g., 240 kHz) and the normal cyclic prefix.

[0067] The time intervals of resources (e.g., communication resources) can be organized according to frames (also called radio frames). Each frame can have a duration, for example, 10 milliseconds (ms). In some implementations, each frame can include multiple subframes. For example, each frame can include 10 subframes, and each subframe can have a duration, for example, 1 ms. In some implementations, each frame can have the same duration. In some implementations, each subframe of a frame can have the same duration.

[0068] Alternatively or concurrently, the time intervals of resources (e.g., communication resources) can be organized according to time slots. For example, a subframe may include a certain number (e.g., quantity) of time slots. The number of time slots in each subframe may also depend on one or more digital technologies supported in the wireless communication system 100. For example, a first digital technology, a second digital technology, a third digital technology, a fourth digital technology, and a fifth digital technology (i.e., ...) associated with corresponding subcarrier intervals of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz. μ =0、 μ =1、 μ =2、 μ =3、 μ =4) One time slot per subframe, two time slots per subframe, four time slots per subframe, eight time slots per subframe, and 16 time slots per subframe can be used, respectively. Each time slot can include a certain number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of time slots in a subframe can depend on the digital technique. For a normal cyclic prefix, a time slot can include 14 symbols. For an extended cyclic prefix (e.g., for a 60 kHz subcarrier spacing), a time slot can include 12 symbols. The relationship between the number of symbols per time slot, the number of time slots per subframe, and the number of time slots per frame for both normal and extended cyclic prefixes can depend on the digital technique. It should be understood that for the first digital technique (e.g., quantity) associated with the first subcarrier spacing (e.g., 15 kHz), μ The reference of =0 can be used interchangeably between subframes and time slots.

[0069] In the wireless communication system 100, the electromagnetic (EM) spectrum can be divided into various categories, frequency bands, frequency channels, etc., based on frequency or wavelength. For example, the wireless communication system 100 can support one or more operating frequency bands, such as frequency range names FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7.125 GHz - 24.25 GHz), FR4 (52.6 GHz - 114.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), and FR5 (114.25 GHz - 300 GHz). In some implementations, network entity 102 and UE 104 can perform wireless communication on one or more operating frequency bands. In some implementations, FR1 can be used by network entity 102 and UE 104, as well as other devices or apparatuses, for cellular communication services (e.g., control information, data). In some implementations, FR2 can be used by network entity 102 and UE 104, as well as other devices or apparatuses, for short-range, high-data-rate capabilities.

[0070] FR1 can be associated with one or more digital technologies (e.g., at least three digital technologies). For example, FR1 can be associated with the following: a first digital technology (e.g., μ =0), which includes a 15 kHz subcarrier spacing; second digital technology (e.g., μ =1), which includes a 30 kHz subcarrier spacing; third digital technology (e.g., μ =2), which includes a subcarrier spacing of 60 kHz. FR2 can be associated with one or more digital technologies (e.g., at least two digital technologies). For example, FR2 can be associated with a third digital technology (e.g., μ =2), which includes a 60 kHz subcarrier spacing; fourth digital technology (e.g., μ =3), which includes a subcarrier spacing of 120 kHz.

[0071] Figure 2 Examples of beam reporting process flows based on the association and mapping between beam sets, according to some exemplary embodiments of this disclosure, are shown. Process flow 200 may involve UE 201 and network entity (e.g., base station) 202. Process flow 200 can be applied to references Figure 1 The wireless communication system 100 shown, for example, UE 201 can be any of UE 104, and network entity 202 can be any of network entity 102. It should be understood that process flow 200 can also be applied to other communication scenarios.

[0072] At 210, network entity 202 can send channel state information (CSI) report configuration and indication information 215 corresponding to the first beam set to UE 201. Accordingly, at 220, UE 201 can receive CSI report configuration and indication information 215 from network entity 202.

[0073] CSI report configuration can be associated with CSI resource configuration, and indication information can specify the second beam set associated with that CSI resource configuration. CSI report configuration and indication information 215 can be sent and received separately. Based on the CSI report configuration and indication information, UE 201 and network entity 202 can align the association and mapping relationship between the first beam set and the second beam set, which will refer to the appendix... Figures 3 to 8 It is described in detail.

[0074] At 230, network entity 202 may transmit a CSI reference signal (CSI-RS) or synchronization signal / PBCH block (SSB) 235 for the second beam set based on CSI resource configuration and indication information. Accordingly, at 240, UE 201 may receive CSI-RS and SSB from network entity 202. In some embodiments, resources of CSI-RS or SSB may be configured for the second beam set, with each resource corresponding to one beam of the second beam set.

[0075] At position 250, UE 201 can measure the received CSI-RS or SSB. For example, UE 201 can determine the L1-RSRSP for each beam in the second beam set. In some embodiments, UE 201 can be configured with an AI / ML model for predicting measurements of the first beam set. The AI / ML model can receive measurements of the second beam set as input and generate measurements of the first beam set as output.

[0076] At 260, UE 201 may send a beam report 265 for the first beam set to network entity 202 based on CSI RS or SSB measurements and CSI report configuration. Correspondingly, at 270, network entity 202 receives the beam report 265 for the first beam set. In some embodiments, UE 201 may predict CSI-RS measurements for the first beam set based on CSI RS measurements for the second beam set, and send a beam report 265 for the first beam set based on the CSI report configuration and the predicted CSI-RS measurements. For example, UE 201 may report the prediction results in the beam report 265 corresponding to the CSI report configuration. The beam report 265 may include CSI-RS resource indicators (CRI) or beam identifiers(s) corresponding to the predicted first K (positive integer) beams and the corresponding L1-RSRPs in the first beam set. For better understanding, in the following text, the first beam set may be interchangeably referred to as set A, and the second beam set may be interchangeably referred to as set B.

[0077] Figure 3 A schematic diagram illustrating examples of associations and mappings between beam sets according to some exemplary embodiments of this disclosure is shown. UE 201 may be configured with a CSI reporting configuration 301 for beam reporting associated with an AI / ML model, wherein the CSI reporting configuration 301 is associated with a CSI resource configuration 302 for beam measurements, and the CSI resource configuration 302 may include a CSI-RS resource set 303, such as an NZP CSI-RS resource set or a CSI synchronization signal / PBCH block (SSB) resource set. For simplicity, CSI-RS resource set and CSI-RS are used hereinafter.

[0078] CSI report configuration 301 can be linked to set A via an indicator 304, where the indicator 304 can be an identifier or index of set A, or an indicator corresponding to a CSI-RS resource set of set A. The indicator 304 can be configured in the RRC parameters of CSI report configuration 301, or in the RRC parameters of CSI resource configuration 302 for beam measurements of set B. CSI resource configuration 302 can include at least one CSI-RS resource set 303 for set B. In some embodiments, the indication information can specify a CSI-RS resource, CSI-RS resource set, or CSI-SSB resource set for a second beam set.

[0079] UE can be based on Figure 2 The indication information received at point 220 is the CSI-RS used for beam measurement. The indication information can specify to the UE the CSI-RS resources used for beam measurement of set B, and an identifier for the beams in set B, where the CSI-RS resources can be elements of a CSI-RS resource set corresponding to the CSI-RS resource configuration. Based on the indication information, the UE can determine the CSI-RS resources for set B from the possible sets B 305. Furthermore, measurements for set B 306 can be input to the AI / ML model 307 deployed at the UE, and predicted measurements for set A 308 are output from model 307.

[0080] Figure 4 Examples of indication information for measuring beam sets according to some exemplary embodiments of the present disclosure are shown. As shown, the indication information may include a CSI-RS resource set ID, resource indicators indicating N CSI-RS resources in the CSI-RS resource set, for example, the number N represents the first N CSI-RS resources of the set. The indication information may also include N TCI states for the selected N CSI-RS resources, wherein each TCI state is used to determine the Rx beam for CSI-RS reception and measurement; and N beam identifiers corresponding to the N CSI-RS resources for identifying beams in set B, wherein each identifier indicates a Tx beam or a pair of beams in set B.

[0081] The indication information can be configured by the NW (e.g., network entity 202) in the RRC, for example, in the RRC parameters. CSI- ResourceConfig A new IE is introduced, and it can be updated via RRC reconfiguration or MAC CE. Using this indication information, the CSI-RS resource set can be indicated by NW to be used for any possible set B, the size of which is no larger than the size of the CSI-RS resource set.

[0082] The second indication information can be sent based on a UE request for set B. For example, the UE can request set B to be aligned with the AI / ML model in the UE that is used for prediction of the current activity of set A, and then the NW can send indication information to indicate the CSI-RS resources for set B.

[0083] For example, a CSI-RS resource set can contain M (positive integer) CSI-RS resources for measuring up to M beams; and set B can contain N (<=M) beams for AI model input; and indication information is configured in the RRC for the default set B and associated with the CSI-RS resource set. Before receiving a MAC CE to update the indication information for beam measurements of set B, the UE can receive CSI-RS based on the indication information for beam measurements of the default set B. Then, the UE receives CSI-RS for beam measurements of set B based on the latest indication information. Specifically, the MAC CE can contain a CSI-RS resource set ID to indicate the CSI-RS resource set, resource indicators to indicate the first N CSI-RS resources selected from the CSI-RS resource set for set B, the TCI status IDs of the N CSI-RS resources, and the corresponding N Tx beam identifiers, such as... Figure 4 As shown in the image.

[0084] CSI-RS resource sets can have three types of time behavior: periodic, semi-persistent, and aperiodic. For these three types of CSI-RS resource sets, the CSI-RS resource set can be configured by RRC, and the associated indication information can also be configured by RRC. In some embodiments, the second indication information can be updated via RRC reconfiguration or MAC CE.

[0085] For periodic CSI-RS resource sets, the UE can determine the timing of CSI-RS based on RRC configuration and receive CSI-RS for the default set B beam measurement; and if the indication information is updated by RRC reconfiguration or MAC CE, the UE can receive CSI-RS for set B beam measurement based on the most recently received indication information.

[0086] For a semi-persistent CSI-RS resource set, this set can be activated by a MAC CE. Once activated, the UE can receive CSI-RS for set B beam measurements based on the RRC configuration before receiving the RRC reconfiguration or MAC CE for updating indication information. If the second indication information is updated by RRC reconfiguration or MAC CE, the UE can receive CSI-RS for set B beam measurements based on the most recently received second indication information.

[0087] For a non-periodic CSI-RS resource set, the set can be triggered by downlink information (DCI) (e.g., DCI format 0-1 / 0-2). After the set is triggered, the UE can receive CSI-RS for set B beam measurements based on the most recently received second indication information.

[0088] For the three types of CSI-RS resource sets, time requirements (T) may need to be met. proce This is the minimum time interval used by network entity 202 to send CSI-RS based on the indication information after sending an RRC reconfiguration or MAC CE carrying indication information. This time interval is defined as the interval between the last symbol of the Physical Uplink Control Channel (PUCCH) transmission carrying the Hybrid Automatic Repeat Request (HARQ)-ACK information corresponding to the Physical Downlink Control Channel (PDSCH) carrying RRC reconfiguration or MAC CE and the first symbol of the CSI-RS transmission. This time interval can be required to be longer than the time required for the UE to obtain the indication information from network entity 202.

[0089] In some embodiments, the UE may assume that N CSI-RSs are transmitted in the first N CSI-RS resources of the CSI-RS resource set, and that the Rx beam used to receive CSI-RSs is determined by the TCI state indicated for each CSI-RS resource, where the Tx beam is associated with a Tx beam identifier, and the Rx beam is determined by the TCI state corresponding to the Tx beam identifier. The reason for indicating the Tx beam is to allow the UE to determine the input data format for the AI / ML model. For example, in the first resource of the N CSI-RS resources, the measured L1-RSRP corresponds to a Tx beam with a first beam identifier and an Rx beam defined by the QCL type D RS indicated by the first TCI state. Therefore, all measured L1-RSRPs in set B can be acquired by the UE, and the UE has knowledge of the Tx-Rx beam pairs of these measured L1-RSRPs. Furthermore, the UE predicts the first K beams in set A based on the measurement results from the AI / ML model, the output of which is aligned with set A.

[0090] In some embodiments, the UE can report the first K beams in set A in a beam report corresponding to the CSI report settings. The content of the beam report may include the CRI of the CSI-RS resource in the CSI-RS resource set corresponding to set A, or the identifier of the beam in set A, such as the relative beam ID in the set. In addition, the beam report may also include the predicted RSRP corresponding to the first K beams.

[0091] Figure 5A schematic diagram illustrating another example of the association and mapping between beam sets according to some exemplary embodiments of this disclosure is shown. For model inference, the UE may be configured with (multiple) CSI reporting configurations 501 for beam reporting, wherein (multiple) CSI reporting configurations may be associated with CSI resource configurations 502 for beam measurements of set B, and CSI resource configurations 502 may contain Y ≥ 1 CSI resource sets, such as resource sets 503-1, 503-2, 503-3, and 503-4 (individually or collectively referred to as "503"), such as the NZP CSI-RS resource set or the CSI-SSB resource set. Each CSI-RS or CSI-SSB resource set is associated with a set B. For simplicity, the CSI-RS resource set is used below.

[0092] The CSI report configuration is linked to set A via indication 504, which can be an identifier for set A or an identifier for the CSI-RS resource set corresponding to set A. Indication 504 for set A can be configured in the RRC parameters of CSI report configuration 501 or in the RRC parameters of CSI-RS resource settings 502 for set B beam measurements, as shown below. Figure 5 As shown in the image.

[0093] For Y=1, meaning the CSI resource configuration includes a single CSI-RS resource set for the second beamset, then set A linked to CSI report configuration 501 is associated with a single set B. In this case, the indication information may include updates to the single CSI-RS resource set. For example, reconfiguring a new CSI-RS resource set for the CSI report configuration via RRC, the new set B can be associated with set A.

[0094] For Y>1, the UE can also be indicated to have one CSI-RS resource set in one of the Y CSI-RS resource sets used for beam measurements of set B. The indication information may include the CSI report configuration ID and the CSI-RS resource set ID. The indication information can be carried by MAC CE signaling. The indication information can be sent based on a UE request for set B; for example, the UE requests set B to be aligned with the AI / ML model of the current activity used for prediction in set A, and then the NW sends an indication to specify the CSI-RS resources for set B.

[0095] Additionally, the UE may be indicated to have a CSI-RS reporting configuration corresponding to set A. For example, the indication information may include an identifier of the CSI reporting configuration.

[0096] Similarly, CSI-RS resource sets can have three types of temporal behavior: periodic, semi-persistent, and aperiodic. For periodic CSI-RS resource sets, the UE can determine the timing of CSI-RS based on RRC configuration and receive CSI-RS for beam measurements of the default set B. If the indication information is updated via RRC reconfiguration or MAC CE, the UE will update its knowledge of CSI-RS for the new set B.

[0097] For a semi-persistent CSI-RS resource set, this set is activated by MAC CE. After the set is activated, the UE can receive CSI-RS for beam measurements of the default set B based on the RRC configuration. Upon receiving this indication information, the UE can update its knowledge of the CSI-RS set for the new set B. After activation via MAC CE, the UE receives and measures the CSI-RS for the updated set.

[0098] For a non-periodic CSI-RS resource set, the set is triggered by DCI (e.g., DCI format 0-1 / 0-2). After the set is triggered, the UE receives CSI-RS for set B beam measurements based on the most recently received indication information.

[0099] The UE can receive CSI-RS for ensemble B-beam measurements based on the most recently indicated CSI-RS resource set. For the three types of CSI-RS resource sets, time requirements (T) may need to be met. proce This is the minimum time interval used by a network entity to send CSI-RS based on the indication information after sending an RRC reconfiguration or MAC CE carrying indication information. This time interval is defined as the interval between the last symbol of the PUCCH transmission carrying HARQ-ACK information corresponding to the PDSCH carrying RRC reconfiguration or MAC CE and the first symbol of the CSI-RS transmission. This time interval can be required to be longer than the time required for the UE to obtain the indication information.

[0100] Then, the UE uses the CSI-RS resources in the CSI-RS resource set to measure the beams transmitted by the NW and obtains the measurement results for set B. Furthermore, based on the measurement results, the UE can predict the top K beams within set A using an AI / ML model whose output is aligned with set A. The UE can report the top K beams in set A in a beam report corresponding to the CSI report settings. This beam report may include the CRI of the CSI-RS resources corresponding to the CSI-RS resource set of set A, or the identifier of the beams in set A, such as the relative beam ID in set A. The beam report may also include the corresponding predicted RSRP.

[0101] Figure 6A schematic diagram illustrating further examples of associations and mappings between beam sets according to some exemplary embodiments of this disclosure is shown. The UE can receive a CSI report configuration 601 for beam reports used for AI model inference output. A CSI report configuration 602 is linked to a CSI resource configuration 602, wherein the CSI resource configuration 602 comprises a CSI-RS resource set 603.

[0102] As shown in the figure, the CSI-RS resource set 603 is configured with a resource list 604 for basic parameters of CSI-RS resources associated with set A; and a resource pool 605 for time-domain and frequency-domain resource mapping of CSI-RS resources associated with set B. In some embodiments, set B may be a subset of set A. Additionally, the CSI-RS resource set 603 has a CSI-RS resource set ID.

[0103] Resource list 604 defines basic parameters for each CSI-RS resource in the CSI-RS resource set. In some embodiments, entries in resource list 604 may include: a resource identifier indicating the CSI-RS resource corresponding to a beam in set A; a periodicity indicating the periodicity of the CSI-RS resource; a scrambling identifier for the CSI-RS; a power control offset indicating the power offset from the PDSCH resource element (RE) to the CSI-RS RE; and a power control offset for the secondary synchronization signal (SSS) indicating the power offset from the CSI-RS RE to the SSSRE. Additionally, the TCI status for all CSI-RS in the set may also be included in the basic resource parameters; for example, each entry in resource list 604 may contain a TCI status ID.

[0104] Resource pool 605 can define the time-domain and frequency-domain resource mappings of at least a portion of the CSI-RS resources in CSI-RS resource set 603. In some embodiments, entries in resource pool 605 can define the positions of multiple orthogonal frequency division multiplexing (OFDM) symbols in the time slots of the CSI-RS resources and the subcarrier occupancy in the physical resource block (PRB). Entries may include: a resource mapping identifier (RM ID) indicating the frequency domain allocation within the PRB of the CSI-RS resource; the time offset of the CSI-RS within a period; the time domain allocation within the PRB of the CSI-RS resource (e.g., indicating the value of the first OFDM symbol in the PRB for the CSI-RS resource); the code division multiplexing (CDM) type of the CSI-RS resource; the number of ports used for the CSI-RS; the density of the CSI-RS resources measured in RE, ports, or PRB; and an indication for wideband or partial-band CSI-RS.

[0105] The UE can also receive indication information for CSI-RS resources used for beam measurements of set B. This indication information is used to select some CSI-RS resources from CSI resource configuration 602. This indication information can be configured in RRC, for example, in RRC parameters. CSI-ResourceConfig A new IE is introduced, and it can be reconfigured by RRC or updated by MAC CE.

[0106] Figure 7 Further examples of indication information for measuring beam sets, according to some exemplary embodiments of this disclosure, are shown. For example... Figure 7 As shown, the indication information may include: the serving cell ID indicating the cell to which the indication information is applied; the bandwidth portion (BWP) of the BWP to which the indication information is applied; the CSI-RS resource set ID indicating the CSI-RS resource set; a first bitmap (RS0, RS1...RSn-1) indicating at least one entry in the resource list 604 of the CSI-RS resource set; and a second bitmap (RS0, RM1...RMm-1) indicating at least one entry in the resource pool 605. For example, the UE can receive the indication information sent from the base station via the MAC CE to indicate the resources from n CSI-RS resources in the set. m Each resource and its corresponding resource mapping.

[0107] In some embodiments, indication information may be sent based on a UE request for set B. For example, a UE may request set B aligned with a currently active AI / ML model deployed at the UE for prediction of set A, and then the network entity sends indication information to specify CSI-RS resources for set B. Similarly, the CSI-RS resource set may have three types of temporal behavior: periodic, semi-persistent, and aperiodic.

[0108] Figure 8 A schematic diagram illustrating a process for generating a beam report based on information indicating a variable mode of a measurement beam set, according to some example embodiments of this disclosure. The variable modes of set B can be defined in the MAC CE carrying the indication information, such as... Figure 7 As shown in the image.

[0109] Upon receiving a MAC CE, the UE can determine the basic parameters of the CSI-RS resources and the time-domain and frequency-domain resource mappings of the CSI-RS resources in the DL BWP based on the received indication information. This DL BWP has a BWP ID in the serving cell, and the serving cell has a serving cell ID. Simultaneously, the MAC CE can activate CSI-RS resources, for example, by activating semi-persistent CSI-RS resources.

[0110] The UE can assume that the CSI-RS is transmitted by the NW in these CSI-RS resources used for beam measurements of set B, and can receive the CSI-RS based on the CSI-RS resources used for beam measurements of set B, and obtain the measurement results for set B. Based on the measurement results for set B, the UE predicts the first K beams in set A through its AI / ML model aligned with set A.

[0111] The UE can report the CRI corresponding to the CSI-RS resource in CSI-RS resource set 603 in the beam report associated with the CSI report configuration. The CSI-RS resource is associated with the predicted first K beams in set A. The beam report may also include the corresponding predicted RSRP.

[0112] In this way, CSI-RS resources can be flexibly configured to adapt to variable set B modes. Additionally, the duration of CSI-RS transmissions for set B beam measurements can be reduced using a common resource pool (e.g., resource pool 605) for CSI-RS associated with set B.

[0113] According to the reference Figures 2 to 8 Some of the embodiments discussed show that the combination of measurement beamsets and reporting beamsets, as well as the effective mode of measurement beamsets between the NW and the UE, can be aligned in a simple and efficient manner.
