Description

Technical Field

[0001] This application relates to a method, apparatus, system, and computer program, and particularly, but not exclusively, to enhanced group-based beam reporting for multi-TRP operation. Background Technology

[0002] A communication system can be viewed as a facility that enables a communication session between two or more entities (such as user terminals, base stations, and / or other nodes) by providing carrier waves between the various entities involved in the communication path. The communication system can be provided, for example, through a communication network and one or more compatible communication devices (also referred to as stations or user equipment) and / or application servers. The communication session can include, for example, data communications used to carry the communication, such as voice, video, email, text messages, multimedia, content data, Time-Sensitive Networking (TSN) streaming, and / or data in industrial applications, such as critical system messages between actuators and controllers, critical sensor data (such as measurements, video feeds, etc.) directed to the control system, etc. Non-limiting examples of the services provided include two-way or multiplexed calls, data communication or multimedia services, and access to data network systems such as the Internet.

[0003] In wireless communication systems, at least a portion of a communication session (e.g., between at least two stations or between at least one station and at least one application server (e.g., for video)) occurs via a wireless link. Examples of wireless systems include Public Land Mobile Networks (PLMNs) operating based on 3GPP radio standards such as E-UTRA, New Radio, satellite-based communication systems, and various wireless local area networks (e.g., wireless local area networks (WLANs)). Wireless systems are typically divided into cells and are therefore often referred to as cellular systems.

[0004] Users can access the communication system through appropriate communication equipment or terminals. A user's communication equipment can be referred to as user equipment (UE) or user device. The communication equipment is equipped with appropriate signal receiving and transmission devices to enable communication, such as enabling access to a communication network or direct communication with other users. The communication equipment can access one or more carriers provided by the network (e.g., a base station in a cell) and transmit and / or receive communication on one or more carriers. In carrier aggregation (CA), two or more carriers are combined into a single channel. In dual connectivity (DC), two carriers from different sites are combined; that is, the user equipment can be dual (or multi-)connected to two (or more) sites.

[0005] Communication systems and related equipment typically operate according to a given standard or specification that defines what the various entities associated with the system are allowed to do and how they should be implemented. Communication protocols and / or parameters used for connectivity are also usually defined. One example of a communication system is UTRAN (3G radio). Other examples include the Long Term Evolution (LTE) of the Universal Mobile Telecommunications System (UMTS), based on E-UTRAN radio access technology, and so-called 5G systems (5GS), including 5G or Next Generation Core (NGC) and 5G access networks based on New Radio (NR) radio access technology. The 3rd Generation Partnership Project (3GPP) is standardizing 5GS, including NR. Summary of the Invention

[0106] Before explaining the examples in detail, refer to Figures 1 to 3 A brief explanation of some general principles of wireless communication systems and mobile communication devices is provided to help understand the technical basis of the described examples.

[0107] In such Figure 1 In the illustrated wireless communication system 100, mobile communication devices or user equipment (UEs) 102, 104, 105 are provided with wireless access via at least one base station (e.g., a next-generation NB, gNB) or similar wireless transmission and / or reception node or point. The base station may be controlled or assisted by at least one suitable controller device to enable its operation and the management of mobile communication devices communicating with the base station. The controller device may be located in the radio access network (e.g., wireless communication system 100) or core network (CN) (not shown) and may be implemented as a central device or its functions may be distributed among several devices. The controller device may be part of the base station and / or provided by a separate entity such as a radio network controller. Figure 1 In the diagram, control units 108 and 109 are shown controlling corresponding macro base stations 106 and 107. The base station control units can be interconnected with other control entities. The control units typically have memory capacity and at least one data processor. Control units and functions can be distributed among multiple control units. In some systems, the control units may be additionally or alternatively located in the radio network controller.

[0108] exist Figure 1 In the diagram, base stations 106 and 107 are shown connected to a wider communication network 113 via gateway 112. Additional gateway functionality may be provided to connect to another network.

[0109] Smaller base stations 116, 118, and 120 may also be connected to network 113, for example, via a separate gateway function and / or via the controller of a macro station. Base stations 116, 118, and 120 may be pico-scale or femto-scale base stations, etc. In this example, stations 116 and 118 are connected via gateway 111, while station 120 is connected via controller device 108. In some embodiments, smaller stations may not be provided. Smaller base stations 116, 118, and 120 may be part of a second network (e.g., a WLAN) and may be WLAN access points (APs).

[0110] Communication devices 102, 104, and 105 can access the communication system based on various access technologies, such as Code Division Multiple Access (CDMA) or Wideband CDMA (WCDMA). Other non-limiting examples include Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), and various schemes such as Interleaved Frequency Division Multiple Access (IFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), and Space Division Multiple Access (SDMA).

[0111] Examples of wireless communication systems are those standardized by the 3rd Generation Partnership Project (3GPP). The latest 3GPP-based development is often referred to as Long Term Evolution (LTE) of Universal Mobile Telecommunications System (UMTS) Radio Access Technology. The various development phases of the 3GPP specification are called releases. The latest development of LTE is often referred to as LTE-Advanced (LTE-A). LTE (LTE-A) employs a radio mobility architecture called Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and a core network called Evolved Packet Core (EPC). Base stations in such systems are called Evolved or Enhanced Node Bs (eNBs) and provide E-UTRAN features such as user plane packet data aggregation / radio link control / media access control / physical layer protocols (PDCP / RLC / MAC / PHY) and control plane radio resource control (RRC) protocol termination. Other examples of radio access systems include those provided by base stations based on technologies such as Wireless Local Area Networks (WLANs) and / or WiMax (Global Microwave Access Interoperability). Base stations can provide coverage for an entire cell or similar radio service area. The core network components include the Mobility Management Entity (MME), the Serving Gateway (S-GW), and the Packet Gateway (P-GW).

[0112] Examples of suitable communication systems are the 5G or NR concepts. The network architecture in NR can be similar to that of advanced LTE. Base stations in an NR system can be referred to as next-generation node Bs (gNBs). Changes to the network architecture can depend on the need to support various radio technologies and more granular QoS support, as well as some on-demand requirements for QoS levels such as supporting user-centric QoE. Network-aware services and applications, and service and application-aware networks, can also bring changes to the architecture. These relate to information-centric networks (ICNs) and user-centric content delivery networks (UC-CDNs). NR can use multiple-input multiple-output (MIMO) antennas, far more base stations or nodes than LTE (the so-called small cell concept), including macro sites operating in cooperation with smaller sites, and may also employ various radio technologies to achieve better coverage and enhanced data rates.

[0113] Future networks can leverage Network Functions Virtualization (NFV), a network architecture concept that proposes virtualizing network node functions as "building blocks" or entities that can be operationally connected or linked together to provide services. Virtualized network functions (VNFs) can include one or more virtual machines running computer program code using standard or general-purpose type servers instead of custom hardware. Cloud computing or data storage can also be utilized. In radio communications, this can mean that node operations are performed at least partially within servers, hosts, or nodes operatively coupled to a remote radio head. Node operations can also be distributed across multiple servers, nodes, or hosts. It should also be understood that the workload allocation between core network operations and base station operations may differ from, or even not exist at all, the workload allocation in LTE.

[0114] An example 5G core network (CN) includes functional entities. The CN is connected to the UE via the radio access network (RAN). The UPF (User Platform Function), whose role is called PSA (PDU Session Anchor), can be responsible for forwarding frames back and forth between the DN (Data Network) and the tunnel established on 5G for (multiple) UEs exchanging services with the DN.

[0115] UPF is controlled by SMF (Session Management Function), which receives policies from PCF (Policy Control Function). CN may also include AMF (Access and Mobility Function).

[0116] Now refer to Figure 2 A more detailed description of possible mobile communication devices, Figure 2A schematic partial cross-sectional view of a communication device 200 is shown. Such a communication device is generally referred to as a user equipment (UE) or terminal. Suitable mobile communication devices can be provided by any device capable of transmitting and receiving radio signals. Non-limiting examples include mobile stations (MS) or mobile devices, such as mobile phones or so-called "smartphones," computers equipped with wireless interface cards or other wireless interface facilities (e.g., USB dongles), personal data assistants (PDAs), or tablet computers equipped with wireless communication capabilities, or any combination of these devices. For example, a mobile communication device can provide communication for carrying data, such as voice, email, text messaging, multimedia, etc. Therefore, users can be supplied and provided with a variety of services via their communication devices.

[0120] In the NR MIMO enhancement of Rel-16, multiple TRP is considered an important component due to the benefits of eMBB operation and the ability to improve the reliability of URLLC services.

[0121] The work item description for MIMO enhancements states that enhancements to multi-TRP / panel transmissions (including improved reliability and robustness by utilizing ideal and non-ideal backhauls) may include specifying downlink control signaling enhancements to efficiently support incoherent joint transmissions, performing studies, and specifying uplink control signaling and / or (multiple) reference signal enhancements, as needed, for multi-TRP technologies required by incoherent joint transmissions and URLLC.

[0122] In Rel-16, RAN1 discusses the URLLC scheme for PDSCH and the basic framework of incoherent joint transmission schemes based on single PDCCH and multiple PDCCH designs. In Rel-17, some objectives are described below.

[0123] Enhanced support for multi-TRP deployments, for both FR1 and FR2:

[0124] a. Using multiple TRPs and / or multiple panels, with Rel.16 reliability characteristics as a baseline, identify and specify features for improving the reliability and robustness of channels other than PDSCH (i.e., PDCCH, PUSCH, and PUCCH).

[0125] b. Identify and specify QCL / TCI-related enhancements to enable inter-cell multi-TRP operation, assuming multi-PDSCH reception based on multi-DCI.

[0126] c. Evaluate and specify beam management-related enhancements, if necessary, to enable simultaneous multi-TRP transmission and multi-panel reception.

[0127] d. Enhanced support for HST-SFN deployment scenarios:

[0128] i. Identify and specify (multiple) solutions for the QCL assumptions of DMRS, such as multiple QCL assumptions for (multiple) the same DMRS port, for DL-only transport.

[0129] ii. Evaluate and, if the advantages compared to the HST Enhanced Baseline Version 16 are demonstrated, specify the QCL / QCL class relationship between DL and UL signals (including (multiple) applicable types and related requirements) through the Unified TCI Framework.

[0130] --------<omitted text>-------------

[0131] 4. Enhance CSI measurement and reporting:

[0132] a. Evaluate and, if necessary, specify CSI reports for DL ​​multi-TRP and / or multi-panel transmissions to enable more dynamic channel / interference assumptions for NCJT, for both FR1 and FR2.

[0133] The following discussion focuses on further enhancements related to beam reporting for multi-TRP transmission based on multiple PDCCH.

[0134] How to support multi-TRP operation based on multiple DCI has been discussed. The main protocol for configuring multi-TRP based on multiple DCI is to support multi-TRP / panel transmission based on multiple PDCCHs, both intra-cell (same cell ID) and inter-cell (different cell IDs). The following RRC configuration can be used to link multiple PDCCH / PDSCH pairs with multiple TRPs. One CORESET in the “PDCCH-config” corresponds to one TRP.

[0135] Based on further discussion, RAN1 agreed to consider a higher-level index per CORESET to differentiate multi-DCI-based multi-TRP transports from other transports.

[0136] If the UE is configured by the higher-layer parameter PDCCH-Config, which contains two distinct values ​​for the CORESETPoolIndex in the ControlResourceSet used for the serving cell's active BWP, the UE can expect to receive multiple PDCCHs, which are scheduled as fully / partially / non-overlapping PDSCHs in the time and frequency domains according to the UE's capabilities. This allows the UE to be configured without joint HARQ ACK feedback or separate HARQ ACK feedback. For a CORESET without a CORESETPoolIndex, the UE can assume that the CORESET is assigned a CORESETPool index of 0.

[0137] Multi-DCI-based multi-TRP transport is designed to support both ideal and non-ideal BH scenarios. Therefore, certain Rel-15 behaviors (such as ordered operations) may be relaxed.

[0138] For multi-TRP based on multiple DCI, when the PDCCH schedules two PDSCH / PUSCH across TRPs, i.e., when the PDCCH is associated with different values ​​of CORESETPoolIndex, the following operations are allowed:

[0139] For PDCCH to PDSCH, for any two HARQ procedure IDs in a given scheduled cell, if the UE is scheduled to begin receiving a first PDSCH starting at symbol j by a PDCCH associated with the value of CORESETPoolIndex ending at symbol i, then the UE can be scheduled to receive a PDSCH that starts earlier than the end of the first PDSCH by using a PDCCH associated with a different value of CORESETPoolIndex ending later than symbol i.

[0140] For PDCCH to PUSCH, for any two HARQ procedure IDs in a given scheduling cell, if the UE is scheduled to start a first PUSCH transmission starting at symbol j by a PDCCH associated with the value of CORESETPoolIndex ending at symbol i, then the UE can be scheduled to transmit a PUSCH that starts earlier than the end of the first PUSCH by a PDCCH associated with a different value of CORESETPoolIndex ending later than symbol i.

[0141] For PDSCH to HARQ-ACK, in a given scheduled cell, the UE can receive the first PDSCH in slot i, where the corresponding HARQ-ACK is allocated to be transmitted in slot j, and the second PDSCH associated with a CORESETPoolndex different from the first PDSCH starts later than the first PDSCH, and the HARQ ACK corresponding to the second PDSCH is allocated to be transmitted in the slot preceding slot j.

[0142] These features are optional for UEs that support multiple DCI-based multi-TRP.

[0143] The discussion in Rel-16 can provide support for the basic characteristics of multi-DCI-based multi-TRP transport, which may require enhancements in different domains (identified by the Rel-17 working scope) to support FR2 operation.

[0144] The multi-DCI-based multi-TRP operation of Rel-16 in FR2 may be limited due to the lack of support for beam management, which prevents efficient operation. Figure 4 A schematic diagram of an example multi-TRP operation in FR2 is shown. When the UE uses multiple panels, not all beams are suitable for incoherent joint transmission (NCJT) toward the UE, even if these beams may be received by the UE individually (via a single TRP).

[0145] In other words, in FR2, there are few instances where a UE can simultaneously receive from two TRPs unless the UE has different panels. Unless the network knows in advance that the UE can receive from both beams, the benefits of scheduling transmissions on both beams may not be realized.

[0146] Group-based beam reporting in Rel-15 can be used for multi-TRP operation. However, using the Rel-15 beam reporting function or any other implementation-specific solution for multi-panel (MP) UEs may not efficiently support multi-TRP operation in FR2.

[0147] In Rel-15, group-based beam reporting is supported, and TS 38.214 records the following items.

[0148] If the UE is configured with CSI-ReportConfig and the higher-layer parameter reportQuantity is set to "cri-RSRP" or "ssb-Index-RSRP",

[0149] - If the UE is configured with the higher-level parameter groupBasedBeamReporting set to "Disabled", the UE does not need to update measurements for more than 64 CSI-RS and / or SSB resources, and the UE should report different CRIs or SSBRIs for each report setting in a single report nrofReportedRS (higher-level configuration).

[0150] - If the UE is configured with the higher-layer parameter groupBasedBeamReporting set to "Enabled", the UE does not need to update measurements for more than 64 CSI-RS and / or SSB resources, and the UE should report two different CRIs or SSBRIs for each report setting in a single reporting instance, where the CSI-RS and / or SSB resources can be received simultaneously by the UE using a single spatial domain receive filter or using multiple simultaneous spatial domain receive filters.

[0151] TS 38.331 records the following items:

[0152] CSI-ReportConfig Information Elements

[0153]

[0154] Group-based beam reporting mechanism and Figure 4 The example scenarios shown combine to allow the UE to report multiple combinations of beam pairs. The following discussion assumes that only 3 reports are allowed due to limited feedback overhead.

[0155] In one variant, the UE can report beam pairs (#Q1, #Q2), (#Q3, #Q1), and (#P1, #P2). In this case, there is no useful combination for multi-TRP operation. There are two possible outcomes: the network requests additional beam pairs, or the UE does not support multi-DCI-based multi-TRP.

[0156] In another variant, the UE can report beam pairs (#P1, #Q2), (#Q3, #Q2), and (#P1, #P2). However, when reporting these pairs, the network is unaware of the panel assumptions used by the UE for single-panel or multi-panel reception. Rel-15 allows the UE to report beams that can be received in a single or multiple panels, without distinguishing between the two modes.

[0157] If the network adopts a conservative approach, then for UEs with a finite beam set, multiple TRPs based on multiple DCI are supported (in this example, only (#P1, #Q2) are supported by two TRPs).

[0158] If the network adopts a less conservative approach and assumes that the (#Q3, #Q2) and (#P1, #P2) pairs are received from a single panel, then for a UE with a set of beam pairs (#P1, #Q2), (#P1, #Q3), (#P2, #Q2), (#P2, #Q3), multi-DCI-based multi-TRP is supported. However, if two combinations ((#P1, #Q3)(#P2, #Q3)) are received at the same panel, multi-DCI-based multi-TRP transmission will fail.

[0159] The issues mentioned in the examples above have different impacts on different multi-TRP schemes.

[0160] In multi-TRP transmission based on a single DCI (with ideal BH between TRPs), reported beam pairs can belong to the same or different TRPs. UE reporting can be inefficient because the network relies on multiple reports to identify beam pairs that the UE can receive simultaneously via multiple TRPs. Using a larger number of reports, beam pairs activated by TRPs can be coordinated, enabling the UE to receive data simultaneously.

[0161] In multi-TRP transmission based on multiple DCI (which can also support non-ideal BH), the beam group reported by the UE can belong to the same or different TRPs (in other words, the reporting is not controlled by the network, so the reporting efficiency is low).

[0162] Furthermore, in both ideal and non-ideal BH scenarios, the TCI state is dynamically indicated by the DCI (from each TRP). When a non-ideal BH exists, the TCI states cannot be coordinated across TRPs. Therefore, the UE cannot simultaneously receive certain beam combinations used by TRPs. To avoid this, the indicated TCI state (from TRP1) should have multiple matching TCIs in TRP2. This flexibility might require a large number of beam pairs for feedback using the Rel-15 framework (since this scheme is not network-controlled). This also takes time, and the beams may become outdated during use.

[0163] Based on the Rel-15 mechanism, at least on the network side, the RS used for beaming can be coordinated between TRPs (e.g., the CSI RS resources to be used by each TRP). Therefore, the network can distinguish whether group-based beaming reports are valid per TRP or across TRPs. However, the UE may not operate efficiently when measuring CSI-RS and may waste reporting resources (because multiple reporting instances may be needed to carry sufficient information toward the network).

[0164] According to the Rel-15 mechanism, at least on the network side, it is unclear whether the beam is received using two panels or a single panel. This information is opaque to the network.

[0165] “If the UE is configured with the higher-layer parameter group BasedBeamReporting set to ‘Enabled’, the UE does not need to update measurements for more than 64 CSI-RS and / or SSB resources, and the UE should report two different CRIs or SSBRIs for each reporting setting in a single reporting instance, where the UE can simultaneously receive CSI-RS or SSB resources through a single spatial domain receive filter or multiple simultaneous spatial domain receive filters.”

[0166] In FR2, multiple TRP transmissions use more than one panel for reception, and the above reporting mechanism helps the network determine the beams that can be used simultaneously at a TRP. Therefore, when the UE is configured with CORESET (CORESETPoolIndex has two different values), the UE behavior used for reporting assumptions should be modified.

[0167] Figure 5 A method according to an example embodiment is illustrated. This method can be performed at a user device.

[0168] In the first step S1, the method includes receiving a configuration at the user equipment that enables group-based beam reporting from the network.

[0169] In the second step S2, the method includes receiving a group-based beam report associated with a first transmission receiving point TRP or a group of TRPs, wherein the group of TRPs includes at least a first TRP and a second TRP.

[0170] In the third step S3, the method includes first determining whether at least two beams are simultaneously received at the user equipment, wherein if a group-based beam report is associated with a first TRP, then each of the at least two beams is associated with the first TRP, and if a group-based beam report is associated with a TRP group, then one of the at least two beams is associated with the first TRP, and at least one other of the at least two beams is associated with a second TRP.

[0171] If at least two beams are received simultaneously at the user equipment, then in the fourth step S4, the method includes determining, at least in part based on the first determination, to report at least two beams to the network.

[0172] Figure 6 A method according to an example embodiment is shown. This method can be performed at a network.

[0173] In the first step T1, the method includes providing the user equipment with a configuration to enable group-based beam reporting from the network.

[0174] In the second step T2, the method includes providing the user equipment with a group-based beam report indicating that it is associated with a first transmit receiving point TRP or a group of TRPs, wherein the group of TRPs includes at least a first TRP and a second TRP.

[0175] In the third step T3, the method includes receiving reports from the user equipment at the network for at least two beams simultaneously received at the user equipment, wherein if a group-based beam report is associated with a first TRP, each of the at least two beams is associated with the first TRP, and if a group-based beam report is associated with a TRP group, one of the at least two beams is associated with the first TRP, and at least one other of the at least two beams is associated with a second TRP.

[0176] Beams can be identified based on Channel State Information Reference Signal (CSI-RS) resources or Synchronization / PBCH Block (SSB) indexes. Determining whether at least two beams are received simultaneously may include: performing beam measurements for at least two beams associated with a first TRP, or one of the at least two beams associated with the first TRP and at least one other beam among the at least two beams associated with a second TRP, and determining whether at least two beams are received simultaneously by the user equipment.

[0177] In other words, when the UE is supported by multi-TRP transmission based on multi-DCI, and if the UE is configured with group-based beam reporting, the UE can be instructed to apply group-based beam reporting per TRP or across TRPs.

[0178] For event-based reporting, simultaneous reception from the first TRP (in the case of per-TRP reporting) or from the first TRP and the second TRP (in the case of cross-TRP reporting) can be configured as an event. Other events can also be configured to trigger reporting (e.g., comparing the RSRP of at least two beams with a threshold).

[0179] When group-based beam reporting is configured to be applied across TRPs, i.e., if group-based beam reporting is associated with a TRP group, the UE reports at least two beams that can be received simultaneously. The beam reporting includes reporting at least two beams, one of which is associated with a first TRP, and at least one other beam is associated with a second TRP. These two beams may include resources received at the user equipment using multiple spatial domain receive filters.

[0180] The first determining step may include determining whether a beam of at least two beams associated with a first TRP is received at the first panel, and whether at least one other beam of at least two beams associated with a second TRP is received at the second panel. That is, the UE may always maintain a given panel for a given TRP. For event-based reporting, reception of a beam of at least two simultaneous beams of a given TRP at a given panel may be configured as an event. Alternatively or alternatively, the method may include providing the network with an indicator of the first panel (e.g., panel ID) and an indicator of the second panel. This condition may not be necessary if the panel ID is reported, as the report may already indicate the panel(s) used.

[0181] In one example embodiment, based on Figure 4 In the scenario shown, the UE can report beam #P1 received from TRP#1 and beam #1 received from TRP2. In another example embodiment, based on Figure 4 In the scenario shown, the UE can report the beam #P1 received from TRP1 and the beams #Q1, Q2, ... Q#K received from TRP2, and any beam pair (beam #P1, beam #Qk) (where K = 1, ... K) can be used in multi-TRP transmission based on multi-DCI.

[0182] When group-based beam reporting is configured to be applied per TRP, i.e., if group-based beam reporting is associated with a first TRP, the UE reports at least two beams that can be received simultaneously, wherein the beam reporting includes reporting at least two beams associated with a given TRP. The at least two beams may include resources received at the user equipment using a single spatial reception filter. In an example embodiment, when group-based beam reporting is configured to be applied per TRP, if those beams can be received using a single spatial domain reception filter, the UE should only report CSI-RS and / or SSB resource indicators.

[0183] The user equipment may include at least two panels. A first determining step may include determining whether at least two beams associated with a first TRP are received at the first panel of the at least two panels. That is, the same panel is used for a given TRP. For event-based reporting, the reception of at least two simultaneous beams from the first TRP at a given panel may be configured as an event. Alternatively or alternatively, as in a cross-TRP embodiment, the method may include providing an indicator of the first panel to the network.

[0184] exist Figure 4 In the example embodiment shown, the UE can report beams #P1 and #P2 received from TRP#1.

[0185] The network can use one or two configurations (per TRP and across TRP) to determine the efficient operating mode, single TRP or multi-TRP transmission, and / or per TRP beam determination when supporting multi-DCI-based multi-TRP transmission.

[0186] In one example embodiment, TRP1 may receive beam reports per TRP as (beam #P1, beam #P2) and across TRPs as (beam #P1, beam #Q1), and the network may decide to use (beam #P1, beam #Q1) and (beam #P2, beam #Q1) to support multi-DCI-based multi-TRP transmissions.

[0187] In another example embodiment, a TRP may require multiple combinations of beam reports before determining TCI activation via MAC-CE. The TCI states activated for TRP1 (up to 8 per TRP in Rel-16) can have a many-to-many relationship with the TCI states activated for TRP2.

[0188] In another example embodiment, a TRP may restrict the use of TCI states to a given set and only change them to a different set after coordination with other TRPs. Other TRPs may also adjust the TCI states used based on this coordination.

[0189] Group-based beamforming and indications associated with a TRP group or a first TRP can be provided via RRC, MAC CE, or DCI (if the indication is explicit). In another example embodiment, the indication can be implicit (e.g., when multiple TRPs are supported based on multiple DCIs (e.g., MAC CE activates two different TCI states for the UE), cross-TRP group-based beamforming is applied)).

[0190] Group-based beam reporting, and the indication associated with a TRP group or a first TRP, can be a higher-level parameter. That is, higher-level parameters can be used to configure whether group-based beam reporting is applied across TRPs or per TRP.

[0191] In another example embodiment, the indication could be an implicit principle (without additional higher-level parameters) for determining whether group-based beam reporting is per TRP or across TRPs.

[0192] In one variant, higher-layer parameters configured within the CORESET (e.g., CORESETPoolIndex) can be used as an implicit principle in determining whether to use group-based beam reporting per TRP or across TRPs. When the UE is configured to receive multi-TRP transmissions (two different values ​​of CORESETPoolIndex are configured for CORESET), and if group-based beam reporting is configured, group-based beam reporting is applied across TRPs.

[0193] When the UE is configured to receive a single TRP transmission (a single value of CORESETPoolIndex is configured for CORESET or CORESETPoolIndex is not configured), and if group-based beam reporting is configured, group-based beam reporting is applied per TRP.

[0194] The method may include associating a beam received at the user equipment with at least one of a first TRP and a second TRP based on a configuration that enables group-based beam reporting.

[0195] Associating the beam received at the user equipment with at least one of the first TRP and the second TRP can be based on a higher-layer index or a quasi-co-address reference. The beam associated with a TRP can be further indicated based on a higher-layer index (CORESETPoolIndex) configured per CORESET, and this higher-layer index can be associated with a given CSI-RS or SSB transmission. Alternatively or alternatively, the beam associated with a TRP can be derived by the UE. Derivation at the UE can be based on a QCL reference for the CSI-RS resource.

[0196] The method may include providing at least two identifiers (e.g., the identifiers may be beam indices), each identifier being associated with one of at least two beams from the user equipment to the network.

[0197] Determining that a report includes at least two beams may include an indication of beam measurements provided for each of the at least two beams. The beam measurements of a beam may include an indication of the beam's RSRP. As in NR Rel-15, both non-differential-based and differential-based reporting for group-based beam reporting can be supported. The reporting format can be reused between non-group-based and group-based schemes. Differential reporting is used when the number of CRIs in the report is greater than 1. The specification specifies that a 7-bit length field is reserved to indicate the quantized L1-RSRP between the maximum and minimum L1-RSRP values ​​(-140 dBm to -44 dBm). Additionally, the specification reserves a 4-bit length field to indicate the differentially encoded L1-RSRP value relative to the maximum value with a 2-bit step.

[0198] If it is determined that at least two beams are not simultaneously received at the user equipment, the method may include determining the strongest beam reported to be received at the user equipment and providing the network with an indication of beam measurement for the strongest beam, as well as a zero indication.

[0199] The method may include, in response to receiving a beam measurement from the user equipment at the network, providing the user equipment with an indication from the network to enable additional group-based beam reporting, wherein the additional group-based beam reporting is associated with a TRP group or a first TRP, and modifying the state of the transport configuration indicator associated with a given TRP.

[0200] Figure 7 An example embodiment is shown in which group-based beam reporting is applied across TRPs, wherein the group-based beam reporting should have at least one beam associated with a first TRP and at least one beam associated with a second TRP. Figure 7 In the example shown, the UE can report eight CRIs (related to two different TRPs (TRP1 and TRP2)).

[0201] CR#1 to CR#4 are indicated as associated with TRP1 where CORESETPoolIndex = 0. CRI#5 to CRI#8 are indicated as associated with CORESETPoolIndex = 1. Even if the UE can receive CR#5 / #6 and CRI#7 / #8, the UE report should include beams from both TRPs.

[0202] When there are two RSs reported, the UE can use the relevant RSRP (absolute or differential) to report (CRI#2, CRI#6), where the combination can be received simultaneously.

[0203] When the number of reported RSs is 3, the UE can use the associated RSRP (absolute or differential) to report (CRI#2, CRI#6, CRI#5), where the report indicates that (CRI#2, CRI#6) and (CRI#2, CRI#5) can be received simultaneously.

[0204] When the number of reported RSs is 4, the UE can use the relevant RSRPs (absolute or differential) to report (CRI#2, CRI#3, CRI#6, CRI#5), where the report indicates that all combinations of two TRPs can be received simultaneously.

[0205] Figure 8 An example embodiment of group-based beam reporting applied per TRP is shown.

[0206] exist Figure 8 In this context, the UE can report 8 CRIs (associated with different TRPs). CRs #1 to CRs #4 are indicated as being associated with TRP1 where CORESETPoolIndex = 0. CRIs #5 to CRIs #8 are indicated as being associated with CORESETPoolIndex = 1.

[0207] The UE can use the associated RSRP (absolute or differential) to report (CRI#5, CRI#6), where the combination can be received simultaneously by a given panel.

[0208] The UE can use the relevant RSRP (absolute or differential) to report (CRI#7, CRI#8), where the combination can be received simultaneously by a given panel.

[0209] Similarly, beamgroup reporting can be performed separately for TRP1.

[0210] If there are no additional enhancements to the beam reporting panel ID from the UE using the above beam reporting, the network can configure cross-TRP group-based beam reporting to obtain feedback from the UE about other TRP beam combinations (CRI#2, CRI#6), so that the network can determine which beams the UE can receive simultaneously.

[0211] If there are additional enhancements to the panel ID reported from the UE using the aforementioned beam reports, the network can export beams that can be used simultaneously, thereby sharing panels between TRPs.

[0212] Figure 9 A signaling diagram for enhanced group-based beam reporting is shown according to an example embodiment.

[0213] exist Figure 9 In the first step shown, the network configures the UE using a CSI reporting configuration with group-based beam reporting enabled (group-based beam reporting is enabled in CSI-ReportingConfig). Within the CSI reporting configuration, the network can also indicate the relevant RS of the beam to the UE (the example above assumes non-zero power (NZP)-CSI-RS).

[0214] In the second step, the network configures or instructs cross-TRP beam reporting for upcoming CSI (group-based beam reporting) instances.

[0215] In the third step, associated NZP-CSI-RS resources (with corresponding beams) are transmitted via multiple TRPs. These CSI-RS correspond to multiple beams transmitted via multiple TRPs, giving the UE sufficient combinations to report to the network. This step can be associated with the Rel-15 P-2 phase of beam management, where CSI-RS-based DL-RS beam tracking is used for L1-RSRP. Here, the UE is configured with a set of CSI-RS resources configured to "Repeat = OFF," consisting of multiple CSI-RS resources with different TCI states (different beams).

[0216] The beam (CSI-RS) associated with each TRP can be indicated or derived by the UE (to map to different panels at the UE). This indication can be based on a higher-layer index, CORESETPoolIndex, and associated with a given CSI-RS resource (beam). Alternatively, the derivation at the UE can be based on a QCL reference for the CSI-RS resource. After the initial beam management phase (P-1 phase in Rel-15), the CSI-RS resource used (narrow beam) has been referenced to the relevant TCI state (primarily the SSB beam) for use as a QCL reference (wider beams are used in P-1 phase), and this SSB is associated with the TRP.

[0217] In the fourth step, the UE performs beam measurement, where the UE selects CSI-RS resources (across TRP) that can be received by the UE simultaneously (e.g., using multiple simultaneous spatial domain receive filters).

[0218] In the fifth step, the UE faces the network ( Figure 9 The TRP1 report is based on the group's beam report (via CSI report).

[0219] If the network is configured with up to 4 CRIs and they are associated with the L1-RSRP value to be reported, the UE can report CRIs associated with two TRPs, where the first indicated CRI can be associated with the first TRP (CORESETPoolIndex = 0).

[0220] In the sixth step, when a report is received at the network, depending on the number of combinations received, the network may trigger an additional report "across TRP" (repeating steps 3-5), or trigger a "per TRP" group-based beam report, or change / activate the TCI state per TRP via MAC-CE signaling.

[0221] In one variant, if additional reporting is required across the TRP, a different Tx beam set can be used for the TRP.

[0222] In another variation, if TRP (TRP1) uses a wider beam compared to other TRPs (TRP2), per-TRP group-based beam reporting can be triggered for TRP1. This allows for faster beam refinement of TRP1 while satisfying multi-TRP reception. This example is in... Figure 9 Steps seven through eleven are further explained.

[0223] In step seven, the network instructs each TRP to report beams based on a group. This step may not be required if the instruction is implicit (when multiple TRPs based on multiple DCIs are supported (e.g., if the MAC CE has already indicated two different TCI states for the UE)).

[0224] In the eighth step, the relevant NZP-CSI-RS resources (with corresponding beams) configured for the CSI report are transmitted via TRP1. This CSI-RS corresponds to multiple beams transmitted via the same TRP, allowing the UE to perform beam refinement.

[0225] In the ninth step, the UE performs beam measurement, where the UE selects CSI-RS resources (per TRP) that can be simultaneously received by the UE (e.g., using a single spatial domain receive filter). The UE can always maintain a given panel for a given TRP (the same panel used for TRP1 in the previous report above).

[0226] In another variant, if the panel ID can also be reported, the above restrictions may not be necessary, since the report can indicate the panel(s) in use.

[0227] In the tenth step, the UE reports a group-based beam report to the network via CSI.

[0228] In step eleven, when a report is received at the network, depending on the number of combinations received, the network may trigger an additional report "across TRP" (repeating steps 3-5), using a different mode of "per TRP" group-based beam reporting, or per TRP via MAC-CE signaling to change / activate the TCI state.

[0229] If the number of combinations reported by the UE is sufficient to support multi-TRP transmission based on multi-DCI, the network proceeds to steps twelve and thirteen.

[0230] In step twelf, the network coordinates useful TCI states toward the UE (based on the reported CRI), where multiple combinations of TCI states used in different TRPs can be received simultaneously at the UE.

[0231] In step thirteen, the TRP activates the TCI state via an independent MAC-CE message for a multi-DCI-based multi-TRP scheme or a single MAC-CE message for a single-DCI-based multi-TRP, and uses the DCI for subsequent data transmission.

[0232] In other variations, some of steps one through twelve can occur simultaneously.

[0233] Figure 10 Example signaling diagrams for reports across TRPs and per TRP group-based reports are shown.

[0234] In step 1, the UE receives a CSI-RS configuration for beam measurement and reporting, wherein the CSI reporting configuration enables group-based beam reporting.

[0235] In step 2, based on the received CSI-RS configuration, the UE can indicate or derive the beam (CSI-RS) associated with the TRP. Figure 9 In the example, CSI-RS #1 and #2 are identified as being used by TRP1, while TRP2 uses other CSI-RS.

[0236] In step 3, the UE receives the configuration or indication of "cross-TRP" group-based beam reporting for the upcoming CSI report (group-based beam reporting) instance.

[0237] In step 4, TRP1 transmits CSI-RS#1 and CSI-RS#2 (corresponding to the beam), while TRP2 transmits CSI-RS#3 and CSI-RS#4.

[0238] In step 5, the UE performs beam measurement, where the UE selects CSI-RS resources (across TRP) that can be received simultaneously by the UE (e.g., using multiple simultaneous spatial domain receive filters).

[0239] In step 6, the UE reports beam pairs based on the measured beams. If at least one beam pair from (CSI-RS#1, CSI-RS#3), (CSI-RS#1, CSI-RS#4), (CSI-RS#2, CSI-RS#3), or (CSI-RS / #2, CSI-RS#4) can be received simultaneously, the UE reports the beam pair. Otherwise, the UE may report the strongest beam, and the bit dedicated to indicating the second beam may be set to zero.

[0240] In step 7, the network node can use the reported beam pair to determine further actions. Actions may include additional CSI reports using cross-TRP group-based beam reporting, triggering per-TRP group-based beam reporting, or using the reported beam to activate the TCI state required for data transmission.

[0241] In step 8, the UE receives the configuration or indication of the “per TRP” group-based beam report for the upcoming CSI report (group-based beam report) instance.

[0242] In step 9, TRP1 transmits CSI-RS#1 and CSI-RS#2 (corresponding to beams). This is to enable additional beam combinations related to the previously reported (in step 6).

[0243] In step 10, the UE performs beam measurement, where the UE selects CSI-RS resources (per TRP) that can be received simultaneously by the UE (e.g., using a single spatial domain receive filter).

[0244] In step 11, the UE reports beam pairs based on the measured beams. If at least one beam pair from (CSI-RS#1, CSI-RS#2) can be received simultaneously, the UE reports the beam pair. Otherwise, the UE may report the strongest beam, and the bit dedicated to indicating the second beam may be set to zero.

[0245] Then repeat step 7 at the network.

[0246] In another variation, such as Figure 11 As shown, the network can trigger cross-TRP beam reports only. Figure 11 Steps 1 to 7 and Figure 10 The steps are the same as those in the previous section.

[0247] In step 7, the network determines to perform an additional cross-TRP beam report.

[0248] In step 8, TRP1 transmits CSI-RS#1 and CSI-RS#2 (corresponding to beams), while TRP2 transmits CSI-RS#5 and CSI-RS#6. Here, TRP2 transmits different beam sets to find more beam pairs that can be received simultaneously.

[0249] In step 9, similar to step 5, the UE performs beam measurement, where the UE selects CSI-RS resources (across TRP) that can be received simultaneously by the UE (using multiple simultaneous spatial domain receive filters).

[0250] In step 10, similar to step 6, the UE reports beam pairs based on the measured beams. If at least one beam pair from (CSI-RS#1, CSI-RS#5), (CSI-RS#1, CSI-RS#6), (CSI-RS#2, CSI-RS#5), or (CSI-RS#2, CSI-RS#6) can be received simultaneously, the UE reports the beam pair. Otherwise, the UE may report the strongest beam, and the bit dedicated to indicating the second beam may be set to zero.
