[001] [001] Beam indication modalities are disclosed. BACKGROUND
[002] [002] In general, all terms used in the present invention must be interpreted according to their common meaning in the relevant technical field, unless another meaning is given clearly and / or is implied from the context in which they are used. All references to an element, device, component, means, steps, etc. they must be openly interpreted as referring to at least one instance of the element, apparatus, component, means, stage, etc. unless explicitly stated otherwise. The steps of any methods described in the present invention need not be performed in the exact order disclosed, unless explicitly described as following or precedent of another step and / or if it is implied that a step must follow or precede another step. Any feature of any of the embodiments disclosed in the present invention can be applied to any other embodiment, where appropriate. Likewise, any advantage of any of the modalities can apply to any other modalities and vice versa. Other objectives, characteristics and advantages of the attached modalities will be evident from the following description.
[003] [003] At the 3GPP TSG RAN WG1 meeting # 90 (21-25 August 2017) the following agreement # 1 was signed, related to the beam indication for the downlink data channel (DL) PDSCH: TABLE 1 - Agreement #1
[004] [004] At the same 3GPP meeting, the agreed N-bit indicator field was extended to provide additional support for downlink scheduling operation as follows: TABLE 2 - Agreement # 2 • Support for DM-RS QCL indication for PDSCH via DCI signaling: o The N-bit indicator field in the agreed WF R1-1714885 is extended to support: ▪ Each state refers to one or two sets of RS, which indicates a QCL ratio for one or two DMRS port group (s), respectively • Each set of RS refers to one or more RS (s) that are QCLed with DM-RS ports within the corresponding DM-RS group • Note: RSs within a set of RS can be of different types • If there is more than one RS per set of RS, each of them can be associated with different QCL parameters, for example, an RS can be associated with spatial QCL while another RS can be associated with other parameters QCL etc. • Configuration of the RS set for each state can be done through upper layer signaling o For example, RRC / RRC + MAC CE o FFS the time when the QCL is applied in relation to the time of the QCL indication
[005] [005] With this extension, each indicator state is associated with one or two sets of RS, where each set of RS refers to one or two groups of DMRS ports of downlink, respectively. This facilitates the indication of QCL in case the multi-TRP (DL CoMP) operation is configured. Different states can correspond to different TRP pairs that support, for example, non-coherent junction transmission (NC-JT) from a pair of TRPs to the UE. The states of the indicators configured with only a single set of RS can be used to support the indication of QCL, both in the case of basic single TRP operation and in the case of multi-TRP operation with, for example, dynamic point selection ( DPS).
[006] [006] Anyway, a set of RS contains one or more DL RSs. In the case of a single DL of RS, a set contains an index for a CSI-RS or SSB. In the case of more than one DL RS, a set can contain, for example, an index for CSI-RS or SSB and a configured TRS. In this case, the PDSCH DMRS can be configured to be QCL with CSI-RS / SSB with respect to spatial parameters, but QCL with TRS with respect to non-spatial parameters (time / frequency). SUMMARY
[007] [007] Throughout this invention the following generic name for the N-bit indicator is used: Transmission Configuration Indicator (TCI). According to some embodiments, this N-bit indicator may be functionally identical to the QCL Reference Indicator (QRI) disclosed in U.S. provisional patent application no. 62544534, filed on August 11, 2017.
[008] [008] TABLE 3 (below) shows an exemplary set of TCI states that can be configured with RRC for a UE. With N-bits, up to 2N TCI states can be defined, since only one set can be selected at a time, some containing a single set of RS and others containing multiple sets of RS to support multi-TRP operations. In the case of a single basic TRP operation, all TCI states would contain only a single set of RS. Also shown is a standard TCI status that can be used, for example, to indicate QCL for the SSB beam index determined by the UE during initial access. As previously agreed, different TCI states can be used to indicate QCL for different types of RS, that is, CSI-RS SSB, periodic, semi-persistent or aperiodic. It is up to the network implementation to configure the states, depending on which mix of DL RSs are used to manage beams. TABLE 3: TCI states used to indicate QCL for PDSCH and
[009] [009] One of the FFS items in Agreement # 1 above concerns the indication or not of QCL for PDCCH, based on the beam indication states for PDSCH. This disclosure proposes the unification of the functionality of indication of
[010] [010] There are currently certain challenges.
[011] [011] One problem is that the gNB needs to configure its analog reception beam (Rx) before receiving the UL signals (PUSCH, PUCCH, SRS) transmitted from the UE. To keep the management of the UL beam under the control of the gNB (agreed upon in 3GPP), a method is needed to control the direction (s) in which the UE transmits UL signals, so that the signal (s) (s) received in the gNB align with a desired Rx beam direction of gNB.
[012] [012] Another problem is that, in some cases, a UE may not have beam matching capability, which means that it is not well calibrated enough to control its direction of Tx beam formation to transmit a UL signal, so that it aligns with the direction of beam formation of Rx to receive a DL signal. In this case, a method is required for the gNB to effectively control the directions in which the UE transmits the PUSCH, PUCCH and SRS, so that the signal (s) received in the gNB align with the direction of the beam of desired gNB Rx.
[013] [013] An additional problem is that there is no known way to perform DL beam management (DL beam selection) based on UL's RS, such as SRS. This can be beneficial in a system that relies mainly on channel reciprocity.
[014] [014] Certain aspects of the present invention and its modalities can provide solutions to these or other challenges.
[015] [015] Some embodiments of this disclosure extend the DL beam indication approach in U.S. application no. 62544534, so that the UL beam indication can be included in the same structure (unified DL and UL beam indication) and can additionally solve one or more problems identified above. One step towards achieving these goals is to allow the RS of UL and the RS of DL in the state of TCI.
[016] [016] For example, gNB signals the UE with a specific TCI, which is used in the UE for the purpose of defining the beam-forming weights of the UE (analog or digital) for the transmission of UL signals (PUSCH, PUSCH, SRS). The advantage of this is that the signals received in the gNB align with the desired gNB analog Rx beam directions, which simplifies the processing of the gNB receiver.
[017] [017] In the case of UL-matched and scaled UEs, the UE makes use of one or more DL RSs (for example, CSI-RS, SSB) that are associated with the signaled TCI in order to adjust their weights beam formation to transmit one or more from among PUSCH, PUCCH or SRS. Since the UE performed a measurement on one or more DL RSs at an earlier time, it is aware of the appropriate Rx beam formation weights associated with each DL RS. The UE then adjusts its Tx beam forming weights so that they are reciprocal to the Rx beam forming weights. Reciprocal may mean, for example, that the resulting Tx beam (s) is aligned with the Rx beam (s) or that the reciprocal spatial QCL remains between the DL RS received in the UE and the UL RS transmitted from the UE.
[018] [018] In the case of UEs without beam matching and UL staggering, the UE makes use of one or more UL RSs (for example, SRS) that are associated with the signaled TCI in order to adjust their beam forming weights of Tx. In one embodiment, gNB performed a measurement on a plurality of SRS resources at an earlier time, when each SRS resource is associated with a different UE Tx beam. Based on these measurements, the gNB indicates to the UE one or more preferred SRS resources, for example, by signaling one or more SRS resource indicators (SRIs) that the UE must associate with one or more TCI states. As the UE is aware of the Tx beam formation weights for each SRS that is already associated with the TCI signaled in the beam indication message, the UE uses the same or similar beam formation weights for the transmission of one or more of the PUSCH, PUCCH and SRS.
[019] [019] In the case of UEs with beam matching and DL scaling, gNB makes use of one or more UL RSs (eg SRS) transmitted by the UE that are associated with the signaled TCI in order to adjust their signal weights. beam formation gNB Tx. In one embodiment, gNB performed a measurement on a plurality of SRS resources at an earlier time, when each SRS resource is associated with a different UE Tx beam. Based on these measurements, the gNB indicates to the UE one or more preferred SRS resources, for example, by signaling one or more SRS resource indicators (SRIs) that the UE must associate with one or more TCI states. Assuming there is UL / DL matching on the gNB side, gNB adjusts its Tx beamforming weights so that they are reciprocal to the gNB Rx beamforming weights used to receive each SRS that is already associated with the signaled TCI . Additionally, as the UE is aware of the UE Tx beam formation weights for each SRS that is already associated with the TCI signaled in the beam indication message, the UE then adjusts its Rx beam formation weights so that they are reciprocal to the Tx beam, forming weights to receive one or more of PDSCH, PDCCH, SSB, TRS, PTRS or CSI-RS.
[020] [020] In short: • The UE adjusts its Tx spatial configuration for the transmission of UL signals, for example, PUSCH, PUCCH, SRS, based on RSs that are associated with a TCI that is signaled to the UE; • The UE adjusts its spatial Rx configuration for the reception of
[021] [021] There are, proposed in the present invention, several modalities that address one or more of the issues disclosed in the present invention.
[022] [022] For example, in one aspect a UE is provided being configured to receive a message comprising configuration information, CI, indicating that a reference signal, RS, is almost colocalized, QCL, with a transmission and adjusting a spatial configuration of Tx for transmission based on an RS associated with the received CIs.
[023] [023] In some modalities, the message is a layer 2 message, MAC-CE message, RRC message or DCI message.
[024] [024] In some modalities, the message is a DCI message and the DCI message comprises the CI and one of: a concession and UL staggering a PUSCH and a DL concession staggering a PDSCH.
[025] [025] In some modalities, the RS associated with the CI received is the RS indicated by the CI received.
[026] [026] In some modalities, the RS associated with the received CIs is one of a DL of DL and an RS of UL.
[027] [027] In some modalities, one or more sets of SR are associated with CI and the RS associated with CI is in at least one among the sets of SR associated with CI.
[028] [028] In some modalities, ICs comprise a transmission configuration indicator, TCI and the RS set (s) is / are associated with the TCI.
[029] [029] In some modalities, the UE is configured to adjust the spatial configuration of Tx so that the spatial configuration is reciprocal to a spatial configuration associated with the RS associated with the received CIs.
[030] [030] In some embodiments, the RS associated with the received CIs is a DL RS and the UE is configured to adjust the spatial configuration of Tx so that it is reciprocal to a spatial configuration of Rx associated with the RS of DL.
[031] [031] In some embodiments, the RS associated with the received CI is an UL RS included in a set of RS associated with the CI and the UE is configured to adjust the spatial configuration of Tx so that it is reciprocal to a second spatial configuration of Tx associated with the RS of UL.
[032] [032] In some modalities, the transmission is a PUSCH, PUCCH or SRS transmission.
[033] [033] In some modalities, the received CIs are associated there i) a first set of RS containing a first RS and ii) a second set of RS containing a second RS, the UE adjusts a first spatial configuration of Tx based on the first RS , the UE adjusts a second spatial Tx configuration based on the second RS, the UE uses the first spatial Tx configuration to transmit PUCCH and the UE uses the second spatial Tx configuration to transmit PUSCH.
[034] [034] In another aspect, the UE is operable to receive the CIs and adjust a spatial reception configuration, Rx, based on an RS associated with the received CIs, where one or more sets of RS are associated with the CI and the RS associated with IC is included in at least one of the sets of RS associated with IC.
[035] [035] In some embodiments, the message is a DCI message and the received DCIs additionally comprise a DL grant by staggering a PDSCH.

[037] [037] In some embodiments, the RS associated with the CI is a UL RS included in a set of RS associated with the CI and the UE is configured to adjust the spatial configuration of Rx so that the spatial configuration of Rx is reciprocal to one spatial configuration of Tx associated with the RS of UL.
[038] [038] In some modalities, the UE is configured to use the spatial Rx configuration adjusted to receive one or more among: PDCCH, PDSCH, SSB, TRS, PTRS and CSI-RS.
[039] [039] In some embodiments, the transmission is a PDSCH or PDCCH transmission.
[040] [040] Certain modalities may provide one or more of the following technical advantage (s). For example, the unified DL and UL beam indication approach disclosed can offer the following advantages: 1) Highly flexible method for the network to dynamically select different beams, from the same or different TRPs, for the transmission of DL data and control signals (PDSCH, PDCCH) and receiving UL data and control signals (PUSCH, PUCCH); 2) Greater system performance and robustness, especially for mm wave operation; 3) Simple and low-cost aerial DL signaling; and 4) Support of UEs with and without DL / UL beam matching.

[054] [054] Some of the modalities contemplated in the present invention will now be described more fully with reference to the accompanying drawings. Other modalities, however, are contained within the scope of the subject disclosed in the present invention, the disclosed subject should not be construed as limited to only the modalities established in the present invention; instead, these modalities are provided as an example to convey the scope of the subject to the technicians in the subject. Additional information can also be found in the document (s) provided in the Appendix.
[055] [055] In all of the modalities below, it is assumed that, for a specific signaled TCI for beam indication purposes, the UE has already made an association between the TCI state and one or more DL (UL) RSs (contained in one or more RS sets, respectively) in which the UE and / or gNB made previous measurements.
[056] [056] Order no. 62544534 discloses two methods to make this association, at least for DL RSs: (1) gNB explicitly signals the DL RS index (s) associated with one or more TCI states and (2) the UE determines implicitly preferred DL RSs to be associated with a TCI state when aperiodic measurements are triggered on one or more sets of DL RSs. In the implicit method, a TCI is included in the same message that triggers the measurement, so that the UE knows which TCI state the preferred DL RSs should be associated with. As disclosed in U.S. application No. 62544534, the DL RSs associated with a TCI state include, but are not limited to, CSI-RS, SSB. As disclosed in the present invention (Mode # 4), UL RSs can additionally be associated with a TCI state, and include, but are not limited to, SRS.
[057] [057] Since the implicit / explicit association between the DL / UL RSs and the TCI states was established at an earlier time, when the UE receives signaling by beam indication, it is able to use the DL or UL RSs associated with the TCI flagged as spatial QCL references. to adjust a transmission spatial filter (Tx) / spatial pre-decoder / beam for transmitting one or more UL signals, for example, PUSCH, PUCCH, SRS. In Mode # 5, the UE uses the UL RSs associated with the signaled TCI as a spatial QCL reference to adjust a spatial reception filter (Rx) / spatial precoder / beam to receive one or more DL signals, for example, PDCCH , PDSCH, SSB, TRS, PTRS or CSI-RS. In the following, the generic terms “Tx / Rx spatial configuration” are used to refer to a Tx / Rx spatial filter, spatial pre-decoder, beam-forming and / or beam weights. Mode # 1 (Direct UL beam indication for UEs with DL / UL beam matching) • By DCI, the UE receives a TCI plus an UL grant by staggering a PUSCH. • Based on a DL RS in at least one set of RS associated with the signaled TCI, the UE adjusts its Tx spatial configuration so that the Tx spatial configuration is reciprocal to the Rx spatial configuration associated with the DL RS (ie , the Rx spatial configuration used to receive the RS from DL). • The UE uses the TX spatial configuration for the purpose of transmitting one or more among PUCCH, PUSCH or SRS and associated DMRS, when applicable.
[058] [058] The spatial Rx configuration associated with the DL RS may, however, have been updated after the transmission of the TCI in the DL concession and the TCI may thus be appropriate to define the spatial Tx configuration of the UE for UL transmission. Mode # 5 (DL beam indication for gNB / UEs with DL / UL beam matching) o By DCI, the UE receives TCI plus a DL scaling assignment from PDSCH. o Based on an UL RS in at least one set of RS associated with the signaled TCI, the UE adjusts its spatial Rx configuration so that it is reciprocal to the spatial Tx configuration associated with the UL RS. o The UE uses the spatial configuration of RX for the purpose of receiving one or more of PDCCH, PDSCH, SSB, TRS, PTRS or CSI-RS and associated DMRS, when applicable. o Above, "reciprocal" can mean one or more of the following o A Tx beam from the UE is oriented in the same direction as an Rx beam or vice versa o The ports of an uplink reference signal (PUCCH DMRS, PUSCH DMRS , SRS) are reciprocally and spatially almost colocalized (QCL) with the RS ports of DL.
[059] [059] Although the subject described in the present invention can be implemented in any appropriate type of system using any suitable components, the modalities disclosed in the present invention are described in relation to a wireless network, such as the example wireless network illustrated in FIG . 1, which shows a wireless network according to some modalities. For simplicity, the wireless network of FIG. 1 represents only network 106, network nodes 160 and 160b and WDs 110, 110b and 110c. In practice, the wireless network may additionally include any additional elements suitable for supporting communication between wireless devices or between a wireless device and another communication device, such as a landline, a service provider or any other network node or of final device. Among the illustrated components, network node 160 and wireless device (WD) 110 are depicted in additional detail. The wireless network may provide communication and other types of services to one or more wireless devices to facilitate access by wireless devices and / or use the services provided by, or through, the wireless network.
[060] [060] The wireless network can comprise and / or interface with any type of communication, telecommunication, data, cellular and / or radio network or other similar type of system. In some embodiments, the wireless network can be configured to operate according to specific standards or other types of predefined rules or procedures. Thus, particular modalities of the wireless network may implement communication standards, such as the Global Mobile Communications System (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE) and / or other standards of 2G, 3G, Suitable 4G or 5G; Wireless local area network (WLAN) standards, such as IEEE 802.11 standards; and / or any other appropriate wireless communication standard, such as worldwide interoperability standards for microwave access (WiMax), Bluetooth, Z-Wave and / or ZigBee.
[061] [061] Network 106 can comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs), data packet networks, optical networks, geographically distributed networks (WANs), local area networks (LANs), wireless local area networks (WLANs), wired networks, wireless networks, metropolitan area networks, and other networks to allow communication between devices.
[062] [062] Network node 160 and WD 110 comprise several components described in more detail below. These components work together to provide a network node and / or wireless device functionality, such as providing wireless connections on a wireless network. In different modalities, the wireless network can comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations and / or any other components or systems that can facilitate or participate in communication data and / or signals or through wired or wireless connections.
[063] [063] As used in the present invention, a network node refers to equipment capable, configured, arranged and / or operable to communicate directly or indirectly with a wireless device and / or with other nodes or network equipment on the network without wireless to enable and / or provide wireless access to the wireless device and / or to perform other functions (for example, administration) on the wireless network. Examples of network nodes include, but are not limited to, access points (APs) (for example, radio access points), base stations (BSs) (for example, base stations, NodeBs, evolved NodeBs (eNBs) and NR NodeBs (gNBs)). Base stations can be categorized based on the amount of coverage they provide (or, stated differently, their transmission power level) and can also be called femto base stations, pico base stations, micro base stations or macro base stations . A base station can be a relay node or a relay donor node that controls a relay. A network node can also include one or more (or all) parts of a distributed base station, such as centralized digital units and / or remote radio units (RRUs), sometimes called remote radio heads (RRHs). Such remote radio units may or may not be integrated with an antenna like a radio integrated with the antenna. Parts of a distributed base station can also be called nodes in a distributed antenna system (DAS). Additional examples of network nodes include multi-standard radio equipment (MSR), such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs) , transmission points, transmission nodes, multicell / multicast coordination entities (MCEs), core network nodes (for example, MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (for example , E-SMLCs) and / or MDTs. As another example, a network node can be a virtual network node as described in more detail below. More generally, however, network nodes can represent any suitable device (or group of devices) capable, configured, organized and / or operable to activate and / or provide a wireless device with access to the wireless network or provide some service to a wireless device that accessed the wireless network.
[064] [064] In FIG. 1, network node 160 includes processing circuitry 170, readable medium by device 180, interface 190, auxiliary equipment 184, power source 186, power circuit assembly 187 and antenna 162. Although network node 160 illustrated in the example wireless network of FIG. 1 may represent a device that includes the illustrated combination of hardware components, other embodiments may comprise network nodes with different combinations of components. It should be understood that a network node comprises any suitable combination of hardware and / or software necessary to perform the tasks, characteristics, functions and methods disclosed in the present invention. In addition, while network node components 160 are represented as single boxes located within a larger box or nested within multiple boxes, in practice, a network node can comprise multiple different physical components that make up a single illustrated component (for example, example, device-readable medium 180 may comprise multiple separate hard drives, as well as multiple RAM modules).
[065] [065] Likewise, network node 160 can be composed of multiple physically separate components (for example, a NodeB component and an RNC component, or a BTS component and a BSC component etc.), which can have their own respective components. In certain scenarios where network node 160 comprises multiple separate components (for example, BTS and BSC components), one or more of the separate components can be shared between multiple network nodes. For example, a single RNC can control multiple NodeBs. In this scenario, each unique NodeB and RNC pair can, in some cases, be considered a single separate network node. In some embodiments, network node 160 can be configured to support multiple radio access technologies (RATs). In such embodiments, some components can be duplicated (for example, readable medium by separate device 180 for the different RATs) and some components can be reused (for example, the same antenna 162 can be shared by the RATs). Network node 160 can also include multiple sets of the various components illustrated for different wireless technologies integrated into network node 160, such as wireless technologies, GSM, WCDMA, LTE, NR, WiFi or Bluetooth. These wireless technologies can be integrated into the same or different chip or set of chips and other components within network node 160.
[066] [066] The processing circuitry 170 is configured to perform any determination, calculation or similar operations
[067] [067] The processing circuitry 170 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application specific integrated circuit, field programmable port arrangement or any other suitable computing device, resource or combination of hardware, software and / or operable coded logic to provide, alone or in conjunction with other network node components 160, such as device-readable medium 180, network node functionality
[068] [068] In some embodiments, the processing circuitry 170 may include one or more radiofrequency (RF) transceiver circuits 172 and baseband processing circuitry 174. In some embodiments, the transceiver circuitry of 174 radio frequency (RF) 172 and baseband processing circuitry 174 may be on separate chips (or chip sets), cards or units, such as radio units and digital units. In alternative embodiments, part or all of the RF transceiver circuitry 172 and baseband processing circuitry 174 may be on the same chip or set of chips, cards or units.
[069] [069] In certain embodiments, part or all of the functionality described in the present invention as being provided by a network node, base station, eNB or other network device can be performed by the processing circuitry 170 executing instructions stored in the readable medium per device 180 or memory within the processing circuit set 170 In alternative embodiments, some or all of the functionality can be provided by the processing circuit set 170 without executing instructions stored on a readable medium by a separate or discrete device, such as a wired way. In any of these modalities, whether executing instructions stored on a device-readable storage medium or not, the processing circuitry 170 can be configured to perform the described functionality. The benefits provided by this functionality are not limited only to the processing circuitry 170 or other components of network node 160, but are enjoyed by network node 160 as a whole and / or by end users and the wireless network in general.
[070] [070] Device-readable medium 180 may comprise any form of volatile or non-volatile computer-readable memory, including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (for example, a hard drive), removable storage media (for example, a flash drive, a Compact Disc (CD), or a Digital Video Disc (DVD)) and / or any other volatile or non-volatile material, readable non-transitory devices and / or computer-executable memory devices that store information, data and / or instructions that can be used by the 170 processing circuitry. device-readable medium 180 can store any appropriate instructions, data or information, including a computer program, software, an application that includes one or more logic, rules as, code, tables etc. and / or other instructions capable of being executed by the processing circuitry 170 and used by the network node 160. Device-readable medium 180 can be used to store any calculations made by the processing circuitry 170 and / or any data received via interface 190. In some embodiments, the processing circuitry 170 and the device-readable medium 180 can be considered integrated.
[071] [071] Interface 190 is used for wired or wireless signaling and / or data communication between network node 160, network 106 and / or WDs 110. As illustrated, interface 190 comprises port (s) / terminal ( is) 194 to send and receive data, for example, to and from network 106 over a wired connection. Interface 190 also includes a radio front end circuit set 192 that can be coupled to, or, in certain embodiments, a part of, antenna 162. The radio front end circuit set 192 comprises filters 198 and amplifiers 196. The radio front end circuitry 192 can be connected to antenna 162 and processing circuitry 170. The radio front end circuitry can be configured to condition the signals communicated between antenna 162 and the processing circuits 170. The radio front end circuit set 192 can receive digital data that must be sent to other network nodes or WDs over a wireless connection.

[099] [099] FIG. 3 is a schematic block diagram illustrating a virtualization environment 300, according to some modalities, in which functions implemented by some modalities can be virtualized. In the present context, virtualizing means creating virtual versions of devices or devices which can include virtualization hardware platforms, storage devices and network resources. As used in the present invention, virtualization can be applied to a node (for example, a virtualized base station or a virtualized radio access node) or to a device (for example, a UE, a wireless device or any other type communication device) or components thereof and refers to an implementation in which at least a portion of the functionality is implemented as one or more virtual components (for example, through one or more applications, components, functions, virtual machines or containers running on one or more physical processing nodes on one or more networks).
[0100] [0100] In some embodiments, some or all of the functions described in the present invention can be implemented as virtual components executed by one or more virtual machines implemented in one or more virtual environments 300 hosted by one or more hardware nodes 330. In addition, in the modalities in which the virtual node is not a radio access node or does not require radio connectivity (for example, a core network node), then the network node can be fully virtualized.
[0101] [0101] The functions can be implemented by one or more 320 applications (which can alternatively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions etc.) operating to implement some of the features, functions and / or benefits of some of the embodiments disclosed in the present invention. Applications 320 run in the virtualization environment 300, which provides hardware 330 comprising the set of processing circuits 360 and memory 390. Memory 390 contains instructions 395 executable by the set of processing circuits 360, whereby application 320 it is operative to provide one or more of the features, benefits and / or functions disclosed in the present invention.
[0102] [0102] The virtualization environment 300 comprises general-purpose or special-purpose network hardware devices 330, comprising a set of one or more processors or 360 processing circuits, which may be commercial off-the-shelf processors (COTS), Circuits Dedicated Application Specific Integrated (ASICs) or any other type of processing circuit, including digital or analog hardware components or special purpose processors. Each hardware device can comprise 390-1 memory, which can be non-persistent memory to temporarily store 395 instructions or software executed by 360 processing circuits. Each hardware device can comprise one or more 370 network interface controllers (NICs) , also known as network interface cards, which include the physical network interface 380. Each hardware device can also include non-transient, persistent and machine-readable 390-2 storage media, having stored in the 395 software and / or instructions executable by the 360 processing circuitry. Software 395 can include any type of software, including software to instantiate one or more virtualization layers 350 (also called hypervisors), software to run virtual machines 340, as well as software that allows perform functions, features and / or benefits described in relation to some modalities described in the present invention.

Different modalities of the virtual appliance instance 320 can be implemented in one or more virtual machines 340 and the implementations can be done in different ways.
[0104] [0104] During operation, the 360 processing circuitry runs software 395 to instantiate the hypervisor or the virtualization layer 350, which can sometimes be referred to as the virtual machine monitor (VMM). The virtualization layer 350 can feature a virtual operating platform that appears as network hardware for the virtual machine
[0105] [0105] As shown in FIG. 3, hardware 330 can be an independent network node with generic or specific components. Hardware 330 can comprise the 3225 antenna and can implement some functions via virtualization. Alternatively, hardware 330 may be part of a larger cluster of hardware (for example, such as in a data center or equipment within customer facilities (CPE)), in which many hardware nodes work together and are managed through Management and Orchestration (MANO) 3100, which, among others, oversees the application lifecycle management 320.
[0106] [0106] Hardware virtualization is referred to in some contexts as virtualization of network functions (NFV). NFV can be used to consolidate many types of network equipment into industry-standard high-volume server hardware, physical switches and physical storage, which can be located in data centers and equipment within the customer's facilities.
[0107] [0107] In the context of NFV, virtual machine 340 can be a software implementation of a physical machine that runs programs as if they were running on a non-virtualized physical machine. Each of the virtual machines 340 and that piece of hardware 330 that runs that virtual machine, whether the hardware dedicated to that virtual machine and / or hardware shared by that virtual machine with other virtual machines 340, forms separate virtual network elements (VNE).
[0108] [0108] Still in the context of NFV, Virtual Network Function (VNF) is responsible for handling specific network functions that run on one or more virtual machines 340 on top of the hardware network infrastructure 330 and corresponds to application 320 in FIG . 3.
[0109] [0109] In some embodiments, one or more 3200 radio units that each include one or more 3220 transmitters and one or more 3210 receivers can be coupled to one or more 3225 antennas. The 3200 radio units can communicate directly with hardware nodes 330 via one or more appropriate network interfaces and can be used in combination with virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station.
[0110] [0110] In some modalities, some signaling can be done with the use of the 3230 control system which can be used alternatively for communication between hardware nodes 330 and radio units 3200.
[0111] [0111] With reference to FIG. 4, according to one embodiment, a communication system includes a telecommunications network 410, such as a cellular network of the 3GPP type, which comprises access network 411, such as a radio access network and core network 414. The network Access points 411 comprise a plurality of base stations 412a, 412b, 412c, such as NBs, eNBs, gNBs or other types of wireless access points, each defining a corresponding coverage area 413a, 413b, 413c. Each base station 412a, 412b, 412c can be connected to core network 414 via a wired or wireless connection 415. A first UE 491 located in coverage area 413c is configured to connect wirelessly or be paged by base station 412c corresponding. A second UE 492 in coverage area 413a can be connected wirelessly to the corresponding base station 412a. While a plurality of UEs 491, 492 is illustrated in this example, the disclosed modalities are equally applicable to a situation in which a single UE is in the coverage area or where a single UE is connecting to the corresponding base station 412.
[0112] [0112] The telecommunications network 410 itself is connected to host computer 430, which can be incorporated into the hardware and / or software of an independent server, a server implemented in the cloud, a distributed server or as processing resources on a server farm . The host computer 430 may be under the ownership or control of a service provider or may be operated by the service provider or on behalf of the service provider. Connections 421 and 422 between telecommunications network 410 and host computer 430 can extend directly from core network 414 to host computer 430 or can pass through an optional intermediate network 420. The Intermediate network 420 can be one of or a combination of more from a public, private or hosted network; intermediate network 420, if any, may be a backbone network or the Internet; in particular, intermediate network 420 may comprise two or more subnets (not shown).
[0113] [0113] The communication system of FIG. 4 as a whole allows connectivity between the connected UEs 491, 492 and the host computer 430. Connectivity can be described as an overhead connection (OTT) 450. The host computer 430 and the connected UEs 491, 492 are configured to communicate data and / or signaling via OTT connection 450, using access network 411, core network 414, any intermediate network 420 and possible additional infrastructures (not shown) as intermediaries. The OTT 450 connection can be transparent in the sense that the participating communication devices through which the OTT 450 connection passes are unaware of the upstream and downstream communications routing. For example, base station 412 cannot or does not need to be informed about the past routing of a receive downlink communication with data originating from host computer 430 to be forwarded (for example, handed over) to a connected UE 491. Similarly, base station 412 need not be aware of the future routing of an outbound uplink communication from UE 491 to host computer 430.

The computer host 510 further comprises processing circuitry 518, which may have storage and / or processing capabilities. In particular, the processing circuitry 518 may comprise one or more programmable processors, application-specific integrated circuits, field programmable port arrangements or combinations thereof (not shown) adapted to execute instructions. Host computer 510 additionally comprises software 511, which is stored or accessible by host computer 510 and executable by processing circuitry 518. Software 511 includes host application 512. Host application 512 may be operable to provide service to a remote user, such as UE 530 connecting via an OTT 550 connection terminating at UE 530 and host computer 510. In providing service to the remote user, host application 512 can provide user data transmitted using the OTT connection
[0116] [0116] The communication system 500 additionally includes the base station 520 provided in a telecommunications system and comprising hardware 525 allowing it to communicate with host computer 510 and UE 530. Hardware 525 may include communication interface 526 to prepare and maintain a wired or wireless connection with a communication device interface other than the communication system 500, as well as the radio interface 527 to prepare and maintain at least the 570 wireless connection with the UE 530 located in a coverage area (not shown in FIG. 5) served by base station 520. Communication interface 526 can be configured to facilitate connection 560 with host computer 510. Connection 560 can be direct or can pass through a main network (not shown in FIG. 5) from the telecommunications system and / or through one or more intermediary networks outside the telecommunications system. In the embodiments shown, the hardware 525 of the base station 520 additionally includes a set of processing circuits 528, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable port arrangements or combinations thereof (not illustrated) adapted to execute instructions. The base station 520 additionally has software 521 stored internally or accessible via an external connection.
[0117] [0117] The communication system 500 additionally includes the UE 530 already mentioned. Your 535 hardware may include a radio interface 537 configured to prepare and maintain the wireless connection 570 with a base station that serves a coverage area in which the UE 530 is located. The UE 530 535 hardware additionally includes a set of 538 processing circuits, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable port arrangements, or combinations thereof (not shown) adapted to execute instructions. The UE 530 additionally comprises software 531 stored or accessible by the UE 530 and executable by the processing circuitry 538. The software 531 includes the client application 532. The client application 532 can be operable to provide a service to a human user or non-human via UE 530 with host computer support
[0118] [0118] Note that host computer 510, base station 520 and UE 530 illustrated in FIG. 5 can be similar or identical to the host computer 430, one of the base stations 412a, 412b, 412c and one of the UEs 491, 492 of FIG. 4, respectively. That is, the internal functioning of these entities can be as shown in FIG. 5 and, independently, the topology of the surrounding network can be the same as that of FIG. 4.
[0119] [0119] In FIG. 5, the OTT 550 connection was designed in an abstract manner to illustrate the communication between host computer 510 and UE 530 through base station 520, without explicit reference to any intermediate devices and the precise routing of messages through these devices. The network infrastructure can determine routing, which can be configured to hide from the UE 530, the service provider operating host computer 510, or both. While the OTT 550 connection is active, the network infrastructure can additionally make decisions by dynamically changing routing (for example, based on consideration of load balancing or network reconfiguration).
[0120] [0120] The wireless connection 570 between the UE 530 and the base station 520 is in accordance with the teachings of the modalities described throughout this invention. One or more of the various modalities improves the performance of the OTT services provided to the UE 530 using the OTT 550 connection, in which the wireless connection 570 forms the last segment. More precisely, the teachings of these modalities can improve network performance by allowing a TRP (for example, the base station) to transmit a beam indication (for example, a QRI) to a UE, which is configured to use the indication beam to determine an advantageous receiver and / or transmitter configuration to which the beam information associates and uses the receiver / transmitter configuration determined to receive data transmitted by the TRP and / or transmit data to the TRP, thereby providing benefits such as reduced overhead, reduced latency, and better quality of the received signal.

In addition, there may be optional network functionality to reconfigure the OTT 550 connection between host computer 510 and UE 530, in response to variations in measurement results. The measurement procedure and / or the network functionality to reconfigure the OTT connection 550 can be implemented in software511 and hardware 515 of host computer 510, in software 531 and hardware 535 of UE 530 or both.

[0183] [0183] The US provisional patent application for which that application claims priority (that is, US application No. 62 / 556,940, filed on September 11, 2017) included an appendix that contained the text of a 3GPP contribution. Some relevant aspects of the 3GPP contribution are reproduced below: Contribution
[0184] [0184] In this contribution, the remaining details of 3 topics related to beam management are discussed: 1) QCL indication (beam) from DL to PDSCH and PDCCH; 2) UL beam indication; and 3) Beam measurement and reporting.
[0185] [0185] On RAN1 # 90 (Prague), agreement 1 (see Table 1 above) was made regarding the beam indication from DL to PDSCH.
[0186] [0186] This agreement # 1 establishes that an N-bit indicator field in the DCI provides at least one QCL spatial reference to an RS DL (CSI-RS or SSB) to assist in the demodulation of PDSCH. A certain value of the indicator is called the status of the indicator and is associated with an index of the RS of DL (CRI or SSB Index). In this case of CSI-RS, the resource can be periodic, semi-persistent or aperiodic. In this agreement, it is for FFS study how the RS index of DL is associated with the status of the indicator, by means of explicit or implicit signaling during an UE measurement. This FFS point will be covered later in this section.
[0187] [0187] At the same meeting, the N-bit indicator field was extended, as shown in Agreement # 2 (see Table 2 above)
[0188] [0188] With this extension, each state of the indicator is associated with one or two sets of RS, where each set of RS refers to one or two groups of DMRS ports, respectively. This facilitates the indication of QCL if multi-TRP transmission (CoMP DL) is configured. Different states may correspond to different TRP pairs that support, for example, non-coherent junction transmission (NC-JT) from a pair of TRPs. The indicator states configured with only a single set of RS can be used to support the QCL indication, both in the case of basic transmission of single TRP and in the case of multi-TRP transmission with, for example, dynamic point selection ( DPS).
[0189] [0189] In any case, a set of RSs contains one or more RSs of
[0190] [0190] Clearly, the functionality supported by the N-bit indicator is analogous to PQI in LTE, used for the purpose of indicating QCL and PDSCH rate matching in 2D format of DCI supporting CoMP operation. One point of difference, however, is that, for NR, it is not clear the need to signal the PDSCH rate matching parameters in the same way. In addition, the indicator is not limited to the case of multi-TRP (CoMP) operation. The dynamic (spatial) indication of QCL is beneficial even for a single TRP Ondasmm (“mmWave”) operation. Therefore, this contribution proposes the adoption of a more general term for the N-bit indicator, namely, the Transmission Configuration Indicator (TCI), to capture the notion that the QCL configuration for a PDSCH transmission is dynamically indicated .
[0191] [0191] Table 3 (above) shows an exemplary set of TCI states that can be configured in RRC for a UE. With N-bits, up to 2N TCI states can be defined, some containing a single set of RS and others containing multiple sets of RS to support multi-TRP operations. In the case of a single basic TRP operation, all TCI states would contain only a single set of RS. Also shown is a standard TCI status that can be used, for example, to indicate QCL for the SSB beam index determined by the UE during initial access. As discussed earlier, different TCI states can be used to indicate QCL for different types of RS, that is, CSI-RS SSB, periodic, semi-persistent or aperiodic. It is up to the network implementation to configure the states, depending on which mix of DL RSs are used to manage beams.
[0192] [0192] One of the FFS items in Agreement # 1 above concerns the indication or not of QCL for PDCCH, based on the beam indication states for PDSCH. Employees note that it makes a lot of sense to harmonize the QCL indication functionality for PDSCH and PDCCH as much as possible. The common thread for demodulation of both PDSCH and PDCCH is that a QCL reference is required in both cases. In addition, for mm-wave operation, it may be necessary for the spatial QCL reference to be dynamically indicated to track the movement / rotation of the UE. This motivates the configuration of a common set of 2N states, in which one subset can be used for PDCCH QCL indication purposes and another potentially overlapping state subset used for PDSCH QCL indication. Examples of two of these subsets are illustrated in Table 3.
[0193] [0193] Where there are differences between PDSCH and PDCCH, QCL indications are: (1) The notion of DMRS port groups is relevant only for PDSCH; (2) A single set of DMRS ports as part of a configured CORESET is only relevant for PDCCH; (3) PDCCH can employ beams wider than PDSCH; and (4) The signaling method used to transmit the QCL indication to the UE may be different for PDSCH and PDCCH.
[0194] [0194] The first three points of difference can be addressed by implementing the network with the appropriate configuration of the TCI states. For example, point (1) is managed by gNB, ensuring that the QCL indication for PDCCH is signaled only for TCI states that contain a single RS set. Point (2) is managed by gNB by configuring potentially different CORESETs in a semi-static manner with the different TCI states used for the PDCCH QCL indication. Point (3) can be managed by gNB by associating some TCI states to RS indexes of DL that are formed based on wider beams and some with narrower beams.
[0195] [0195] It is useful to note that a CORESET in NR assumes the role of an E-PDCCH in LTE. Similar to LTE, different CORESETs associated with different TCI states can allow dynamic point switching of control channel transmissions in the case of multi-TRP operation. Even for single TRP operation, the use of different CORESETs for different TCI states can enable a robustness of the PDCCH through the UE by monitoring the different CORESETs transmitted in different beams simultaneously or similar to TDM.
[0196] [0196] Note 1: A CORESET in the NR assumes the role of an E-PDCCH in LTE. Different CORESETs associated with different Transmission Configuration Indicator (TCI) states allow dynamic beam switching of control channel transmissions on a single TRP or between multiple TRPs.
[0197] [0197] Finally, point (4) is already addressed in the existing agreements. Specifically, the indication of QCL for PDSCH is performed by the DCI, as discussed above. According to Agreement # 3 shown in Table 4 below from RAN1 # 90 (Prague), the indication of QCL for PDCCH is only by RRC or through a combination of RRC + MAC-CE signaling.
[0198] [0198] Another item of the FFS in Agreement # 3 is whether the QCL indication for PDCCH may or may not refer to an aperiodic CSI-RS feature. Whereas aperiodic CSI-RS features are supported for PDSCH beam management procedures; from the point of view of network flexibility, there seems to be no fundamental reason why aperiodic CSI-RS resources should be hindered for managing PDCCH bundles. In some scenarios, a baseline beam management procedure can use the same beam for both PDSCH and PDCCH and that beam can be determined based on aperiodic measurements. Based on the discussion above, this contribution makes the following brief proposals:
[0199] [0199] Proposal 1: The QCL indication for both PDSCH and PDCCH is based on the same or different subsets of a common set of 2N States of the Transmission Configuration Indicator (TCI). The value of N is FFS, for example, N = 3.
[0200] [0200] Proposal 2: The indication of QCL for both PDSCH and PDCCH allows the states of the Transmission Configuration Indicator (TCI) to refer to the aperiodic CSI-RS resources.
[0201] [0201] Proposal 3: The indication of QCL based on DCI for PDCCH should be supported in addition to RRC only or RRC + MAC-CE.
[0202] [0202] This contribution additionally makes the following proposal shown in Table 5 below: TABLE 5 - Proposal 4: QCL indication for PDSCH and PDCCH • A list of up to 2N Transmission Configuration Indication (TCI) states are defined for the UE at least for the purpose of indicating QCL for PDSCH DMRS and PDCCH DMRS o Each TCI state can have one or two sets of RS, according to the previous agreement the FFS: N value, for example, N = [ 8] • For PDSCH QCL indication: o The UE is signaled with the NCI bit TCI field in the DCI that selects one of the 2N defined TCI states that provide a reference to one or two sets of RS that are QCL with DMRS port (s) of PDSCH scaled to UE, as per previous agreement • For PDCCH QCL indication: o UE is configured only by RRC or RRC + MAC CE signaling with one of 2N defined TCI states that provide a reference to a set of RS that is QCL with the DMC port (s) of the PDCCH in a CORESET configur with a specific UE search space ▪ FFS: use of DCI signaling ▪ FFS: CORESET containing common search space ▪ Note: CORESETs can be configured differently for different TCI states, for example, for multi-TRP operation • Each set of RS within a TCI state refers to one or more DL RS (s) that are QCL with the ports within a PDSCH DMRS port group or QCL with the PDCCH DMRS port (s) o TCI state with two sets of RS is used only in the case of two groups of DMRS ports for PDSCH o A TCI state with one set of RS is always used in the case of DMRS for PDCCH • An RS in a set of RS can say with respect to any of the following types of DL RS: SSB o CSI-RS Periodic o CSI-RS Aperiódico o CSI-RS semi-persistent o FFS: TRS depending on the outcome of the discussions on the agenda item
[0203] [0203] The discussion and proposals above focus on harmonizing the QCL indication for both PDSCH and PDCCH by signaling a Transmission Configuration Indicator (TCI) value. However, what is still open is the signaling mechanism for defining / updating the DL RS index (CSI-RS Resource Index or SSB index) associated with each set of RS in a TCI state. This is necessary to establish / update the spatial QCL reference in a TCI state before the beam indication signaling is performed based on the signaling of a TCI state index.
[0204] [0204] Agreement # 1 identifies two FFS mechanisms for updating an RS index of DL in a set of RS: (1) explicit signaling of the RS index and (2) implicit association of the RS index (s) with the set of RS based on the measurement of the UE. Mechanism-1 (explicit update of a TCI state) is simple and must be supported. For example, a periodic beam scan, based on a large number of SSBs (up to 64 mmwaves allowed) or a large number of periodic CSI-RS resources (p-CSI-RS), can be used during a P1 procedure. The UE can be configured to periodically report the N major RSRPs and corresponding benchmark indices, for example, CRIs, SSB indices. The gNB decides which (or if all) subsets the RS indices should be associated with which state (s) of TCI. The gNB then signals the TCI status index (s), the RS index (s) and the RS index (s) from DL to the UE that updates its own configuration of TCI status with the signaled RS index (s). This updates the spatial QCL reference that the UE should use for demodulating PDCCH / PDSCH when indicated in a future QCL indication message. This reference remains valid until the next time it is updated. Updates are needed, for example, to track the movement / rotation of the UE. Of course, the required refresh rate depends on how quickly the UE moves.
[0205] [0205] Although the above process is described for p-CSI-RS resources,
[0206] [0206] Mechanism-2 (implicit update of a TCI state) is useful for aperture-fired P2 or P3 refinement procedures and must also be supported. In Mechanism-2, the UE is triggered to perform a measurement on a set or sets of aperiodic CSI-RS resources for beam management purposes on the Tx side or on the Rx side. The UE receives the measurement trigger plus a TCI status index via DCI. In the example above, the state of TCI can be the same as that started explicitly. When the UE receives the TCI status index together with the measurement trigger, the UE must interpret this as an instruction to perform the measurement and replace the RS index in each set of RS with the preferred CRI of each set of resources it measures , respectively. Such RS indices become the new QCL references for the signaled TCI state and remain valid until the next time that a measurement trigger with the same TCI index is received.
[0207] [0207] Based on the above discussion, this contribution makes the following brief proposals:
[0208] [0208] Proposal 4: Mechanism-1 (explicit update of the RS index (s) of a TCI state) is supported for SSB and p / sp / ap-CSI-RS resources. Mechanism-2 (implicitly updating the RS index (s) of a TCI state) is supported for ap-CSI-RS features. For Mechanism-2, the UE can wait for the DCI to receive a measurement trigger for the ap-CSI-RS resources plus a TCI status index.
[0209] [0209] This contribution additionally makes the following more comprehensive proposal shown in Table 6 below: Table 6 - Proposed procedures for defining / updating health status
[0210] [0210] Many of the procedures in the beam indication have been designed under the assumption that the PDCCH and PDSCH beams are updated separately. The indication schemes were designed assuming that the UE must adjust its Rx beams differently for the reception of PDCCH and PDSCH.
[0211] [0211] However, in many cases, this level of freedom is unnecessary. Both PDCCH and PDSCH must be transmitted with beams that provide the best SINR at the receiver. In many cases, this is the narrowest beam. Then, it is likely that the target BLER for PDCCH and PDSCH will be different and this will be achieved by the proper selection of the PDSCH scheduling mechanism and PDCCH format.
[0212] [0212] Note: A very common perception is that PDCCH and PDSCH are transmitted using the same beam.
[0213] [0213] In addition, the implementation of independent PDCCH and PDSCH beams leads to an increase in signaling. The extra amount depends on how often the PDCCH and PDSCH beams are updated.
[0214] [0214] Furthermore, the introduction of the possibility to switch between PDCCH and PDSCH leads to a more complex UE implementation than the case in which the Rx beam switches are limited to being between the slots. For these reasons, this contribution proposes: NR must support a configuration in which the beam indications for PDSCH are also valid for PDCCH.
[0215] [0215] In the previous section, the DL beam indication is discussed for both PDSCH and PDCCH. The DL beam indication consists of signaling a TCI to the UE that provides one or more spatial QCL references that can be used by the UE to adjust its spatial Rx configuration, that is, spatial filter / spatial precoder / beam for demodulation purposes PDSCH and PDCCH. Maintaining several different TCI states allows flexibility for gNB to dynamically switch between different Tx beams, either within a TRP or between TRPs. This is beneficial, for example, for the MU-MIMO operation, making it possible to scale different users on different candidate beams and multi-TRP operation to support one or both dynamic point selections (DPS) or non-coherent junction transmission (NC-JT ).
[0216] [0216] Although the indication of the DL beam has been discussed extensively, the indication of the UL beam has not received much attention. Of course, if the DL beam indication is used, some form of beam indication on the uplink is beneficial to assist the UE in adjusting its Tx spatial configuration, that is, spatial filter / spatial precoder / beam for the purpose of transmitting signal signals. UL (PUSCH, PUCCH and SRS). This simplifies the operation of gNB in the demodulation of PUSCH and PUCCH in which the signals received in the gNB are aligned with a direction of the desired gNB analog beam.
[0217] [0217] Since a framework for the indication of DL beam has already been agreed, it makes sense to take advantage of this framework as much as possible for the indication of UL beam. To allow the UE to adjust its Tx spatial configuration to transmit PUSCH / PUCCH / SRS, a spatial QCL reference is required. In the case of UEs with UL / DL beam matching, a natural candidate is the DL of RS (CSI-RS or SSB) associated with the TCI which is signaled in the DCI for the purpose of indicating the DL beam. This can be used by the UE to adjust its Tx spatial configuration so that it is reciprocal to the Rx spatial configuration with the DL RS. Here, reciprocal can mean that an EU Tx beam is oriented in the same direction as an Rx beam. It can also mean that the ports of the transmitted uplink reference signal (SRS or DMRS of PUSCH / PUCCH) are reciprocal and spatially almost colocalized with the ports of the RS of DL. However, the reciprocal QCL notation was not agreed in RAN1. Regardless, the notion of reciprocal beam senses is quite natural.
[0218] [0218] In the case of a DL beam indication to assist in receiving the PDSCH, it was agreed that the scaling DCIs contain the TCI field. That is, the TCI is part of an attribution or concession of DL. For the UL beam indication case, it makes sense to extend this framework so that the TCI field is included in the DCIs that also scale PUSCH. That is, the TCI can also be part of a UL concession. This can be useful in UL heavy traffic scenarios, where there can be a lot of time between DCIs that contain DL assignments.
[0219] [0219] In the above discussion, the UE uses a DL RS (CSI-RS, SSB) as a QCL spatial reference to adjust its Tx spatial configuration. However, there are at least two use cases in which it is beneficial for the UE to make use of an UL RS (for example, SRS) as a QCL spatial reference: (1) UL beam indication for UEs without UL beam matching / DL and (2) DL beam indication for reciprocity based operation. To support these use cases, it makes sense to extend the beam indication framework, so that UL RSs can also be associated with TCI states, for example, as another type of RS to be included in the RS set of a TCI status. The particular SRS associated with the state of TCI can be based on a previous gNB measurement on a set of SRS resources transmitted by the UE, for example, in a U3 procedure. Based on this measurement, the gNB explicitly flags the UE with an SRS resource indicator (SRI) indicating the preferred SRS resource together with the TCI to which the UE must associate the indicated SRI. Thus, when the TCI is signaled in DCI at a later time for the purpose of indicating the DL or UL beam, the associated UL RS provides the UE with the necessary spatial QCL reference.
[0220] [0220] For the use case (1), the UE adjusts its Tx spatial configuration so that it aligns with the Tx spatial configuration associated with the UL RS (SRS) contained in the TCI state signaled through the DCI in a concession UL. In this way, the gNB can control the direction of receiving PUSCH / PUSCH / SRS for UEs without UL / DL beam matching. For the use case (2), the UE adjusts its spatial configuration of Rx so that it is reciprocal to the spatial configuration of Tx associated with the UL RS (SRS) contained in the state of TCI signaled through the DCI in a DL concession. In this way, gNB can base its DL beam formation decisions for transmission of PDSCH / PDCCH / CSI-RS / PTRS / TRS, based on reciprocity measurements (SRS), while providing the UE with the necessary spatial QCL reference to adjust your space Rx configuration.
[0221] [0221] Based on the above discussion, the following is proposed:
[0222] [0222] Proposal 5: To allow the indication of UL beam, NR supports signaling a TCI in a DCI message containing a UL grant to assist the UE in adjusting its spatial Tx (beam) configuration for PUSCH transmission purposes / PUCCH / SRS.
[0223] [0223] Proposal 6: To allow (1) DL beam indication for reciprocity operation or (2) UL beam indication for UEs without UL / DL beam match, NR supports the inclusion of an SRS feature in a set of RS associated with a TCI state to provide the UE with a spatial QCL reference to adjust its spatial configuration Rx / Tx (beam).
[0224] [0224] On RAN1 # 90 (Prague), the following agreement # 4 was made regarding the L1-RSRP measurements based on the SSB and the configuration of the CSI-RS resources for beam management. TABLE 7 - Agreement # 4 • Support for L1-RSRP reporting of measurements in the SS block for beam management procedures • The following configurations for L1-RSRP reporting for beam management are supported • SS block only (supported mandatory by UE) • CSI-RS only (with mandatory support by UE) • SS block + CS1-RS independent L1 RSRP report • L1-RSRP junction using SS block QCL-ed + CSI-RS is optionally supported by UE (with optional support by UE) Working assumption: • For CSI-RS beam management, NR supports an upper layer configuration of a set of single-symbol CSI-RS features, where o set contains an information element (IE) indicating whether the repetition is "on / off" • Obs .: In this context, the repetition "on / off" means: "On": the UE can assume that the gNB maintains a beam Fixed Tx or "Off": The UE cannot assume that the gNB maintains a fixed Tx beam • Note: This does NOT mean necessarily mean that the CSI-RS resources in a set occupy adjacent symbols
[0225] [0225] Here, the 3rd approach listed in the first agreement: SS + CSI-RS block with independent L1 RSRP report is considered. It seems appropriate to extend the bundle and CSI management framework to include SSB-based resource configurations and reporting in a manner analogous to CSI-RS-based configurations.
[0226] [0226] A use case is considered in which SSB is used for the purpose of identifying new beams as they appear due to the movement and / or rotation of the UE. Since SSB beams typically scan most of the coverage area of a TRP, the use of SS blocks for beam management can lighten some of the load in the UE-specific CSI-RS configuration. Here, the CSI-RS is used in an aperiodic way to refine thick beams identified by means of SS block measurements, thus avoiding the configuration of the CSI-RS to sweep the entire coverage area.
[0227] [0227] FIG. 12 shows an example configuration to support this use case. In this diagram, there are two aperiodic reporting configurations linked to a resource configuration containing two sets of aperiodic CSI-RS resources used for beam refinement purposes. One set is configured with the IE repetition set to OFF (see working assumption above) and another with the repetition set to ON. The DCIs jointly select Report Configuration 1 + Set 1 when triggering a P2 procedure (gNB Tx beam scan) and jointly select Report Configuration 2 + Set 2 when triggering a P3 procedure (Rx beam scan) EU).
[0228] [0228] Furthermore, FIG. 12 shows a diagram with Resource Configuration 2, which contains a set of periodic SSB resources. This is linked to Report Configuration 3 which, in this example, is configured as periodic. Similar configurations can be constructed in a simple way for the case of semi-persistent or aperiodic reports in the SSB. In this example, the UE is configured to report the two main SSBs and the corresponding SSB indexes periodically, for example, once every 20 ms.
[0229] [0229] One consideration in configuring L1-RSRP reports based on SSB is the uplink signaling (UCI) overhead. In order to uniquely identify an SS block from an unknown and arbitrary TRP, a large number of bits may be required. The PSS and SSS together uniquely identify a cell ID and it was agreed to support around 1000 cell IDs (approximately twice as much as LTE). Therefore, this requires the order of 10 bits. Up to 64 SS blocks can be configured in an SS burst set, that is, up to 6 additional bits are required to identify the SS block time index. This results in 16 bits, and if someone counts an additional 7 bits to represent an RSRP value, at least 23 bits are required to signal an SS beam index and a corresponding RSRP measurement. This is a very high value, considering which payload sizes are being considered for PUCCH. Even if the report is restricted to the cell, 6 bits will be needed to identify the SS beam index. Note that UL signaling must be sized to handle the situation in which all 64 SSBs are transmitted, although a much smaller number of SSBs is normally used.
[0230] [0230] An approach to reduce overhead is to configure the UE using RRC with a table containing a mapping between complete SS block identities and short measurement identities. The complete SS block identity would include ~ 10bits representing the PSS / SSS identity and up to 6 bits representing the SS block time index, while the short measuring identity would be 6 bits or less, depending how many SSBs are configured. The short identity would be the one used in the measurement report. Using a short identity in this way, it would also be possible to perform measurements on a pre-configured subset of the available SS block bundles, instead of the complete set. This approach is similar to the CSI framework, in which the UE is configured with one or more sets of CSI-RS resources through RRC. Each CSI-RS resource within a set is then identified by a short identifier, the CRI.
[0231] [0231] Such an approach is shown in FIG. 12, in which the UE is configured for measurement in a set of 8 SSB resources and the configuration defined in Resource Configuration 2 contains an IE specifying the short ID configuration, that is, mapping between long and short IDs. In this case, since only 8 SSB features are configured, the short ID has only 3 bits. Using the example of 7 bits per RSRP value, the total overhead per reporting instance in this example would be 2 * 7 + 2 * 3 = 20 bits. If the RSRP resolution is reduced and / or if differential RSRP reports are used, this can be further reduced.
[0232] [0232] Based on the above discussion, the following is proposed:
[0233] [0233] Proposal 7: Extend the beam management / CSI framework to allow the configuration of a set of SSB resources within a resource configuration in which the UE should perform L1-RSRP measurements. The SSB resource set can be all or a subset of SSBs transmitted from a TRP. Extend the framework to allow the configuration of a report configuration linked to the aforementioned resource configuration. The report configuration contains at least the following parameters: behavior in the time domain = [eriodic, semi-persistent, aperiodic] and N = the number of reported RSRPs. The maximum value of N is FFS.
[0234] [0234] Proposal 8: For L1-RSRP reports in SSB, support UE configuration with a mapping between the complete SS block identity and a short measurement identity (6 or less bits). The short measurement identity is used in measurement reports and uniquely identifies an SSB resource within a set of configured SSB resources. An IE that specifies the short ID configuration associates with the configured set of SSB resources within a resource configuration.
[0235] [0235] In RAN1 # 90 (Prague), the following Agreement # 5 was made in relation to the parameters for measurement and reporting: TABLE 8 - Agreement # 5 • At least for beam reports based on non-clusters, considering the following values of parameters for further analysis - For maximum beam numbers of TX for a UE to measure in a given reporting instance: the candidate value is, for example, around K = [64] - For maximum beam numbers of TX reported by one UE per reporting instance, for example, N = [1, 2, 4, 8] - For L1-RSRP levels, the candidate value is, for example, around [100] • Considering the maximum range of L1-RSRP, for example, from X dBm to Y dBm • Considering the step size of L1-RSRP, for example, Z dB • ...
[0236] [0236] In the above agreement, the maximum number of beams that a UE is expected to measure before notification is [64]. This number corresponds to the maximum number of SSBs in a cell, so in this context, this seems reasonable, since the UE will be able to hear all SS blocks transmitted during a set of SS bursts. However, it is important to note that for aperiodic CSI-RS measurements, which are often used for refinement purposes, the number is significantly less, perhaps less than
[0237] [0237] For L1-RSRP levels, a frequently quoted number is 7 bits, corresponding to 128 levels. This number comes from the L3-RSRP reports for RRM purposes. RAN4 is still evaluating the RSRP accuracy requirements for managing beams based on CSI-RS, considering different density values, so it is too early to decide on an appropriate value. However, one observation is that differential reporting can reduce overhead. For example, if N RSRPs are reported, the largest can be quantized, for example, with 7 bits, and the differential values with a smaller number of bits.
