Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. patent application No. 17 / 819,141, filed on August 11, 2022, entitled "UPLINK TRANSMISSIONCONFIGURATION INDICATOR STATES IN A UNIFIED TRANSMISSION CONFIGURATIONINDICATOR STATE," which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for unifying uplink transmission configuration indicator (TCI) states in TCI states. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0030] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0031] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0033] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). For another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0034] In some examples, the network node 110 is or includes a network node (such as an RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0035] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. The network node may support one or more (e.g., three) cells. In some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0036] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not another base station function. In this way, a single device may include more than one base station.

[0037] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0038] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0039] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0040] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.

[0041] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0042] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0043] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0044] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., according to frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0045] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0046] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0047] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a beam indication associated with a unified transmit configuration indicator (TCI) state indication from a network node, wherein the unified TCI state indication includes an indication of one or more downlink single frequency network (SFN) TCI states; and send an uplink communication to the network node using an uplink TCI state that uses uplink resources not associated with the unified TCI state indication, wherein one or more parameters associated with the uplink TCI state are based at least in part on the unified TCI state indication or at least in part on another TCI state indication signal. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0048] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send a beam indication associated with a UE, the beam indication being associated with a unified TCI state indication, wherein the unified TCI state indication includes an indication of one or more downlink SFN TCI states; and receive uplink communications using uplink resources not associated with the unified TCI state indication, wherein the uplink communications are associated with the UE and the uplink TCI state, and wherein one or more parameters associated with the uplink TCI state are based at least in part on the unified TCI state indication or at least in part on another TCI state indication signal. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0049] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The content described is different.

[0050] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0051] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120, and may provide data symbols for UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0052] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0053] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0054] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0055] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 7 to 11 ) or any aspect of any of the methods described herein.

[0056] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 7 to 11 ) or any aspect of any of the methods described herein.

[0057] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 8 The process of 800 Fig. 9 900 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0058] In some aspects, the UE 120 includes means for receiving a beam indication associated with a unified TCI state indication from a network node, wherein the unified TCI state indication includes an indication of one or more downlink SFN TCI states; and / or sending an uplink communication using uplink resources not associated with the unified TCI state indication to the network node using an uplink TCI state, wherein one or more parameters associated with the uplink TCI state are based at least in part on the unified TCI state indication or at least in part on another TCI state indication signal. Means for the UE 120 to perform operations described herein may include, for example, one or more of the following: the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0059] In some aspects, the network node 110 includes means for sending a beam indication associated with a UE, the beam indication being associated with a unified TCI state indication, wherein the unified TCI state indication includes an indication of one or more downlink SFNTCI states; and / or means for receiving uplink communications using uplink resources not associated with the unified TCI state indication, wherein the uplink communications are associated with the UE and the uplink TCI state, and wherein one or more parameters associated with the uplink TCI state are based at least in part on the unified TCI state indication or at least in part on another TCI state indication signal. In some aspects, the means for the network node 110 to perform operations described herein may include, for example, one or more of the following: the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0060] Although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0061] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The content described is different.

[0062] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also called an independent base station or a monolithic base station) or a decomposed base station, etc. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0063] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0064] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0065] Figure 3 3 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0066] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0067] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0068] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, depending at least in part on a functional partition such as that defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like. In some aspects, the DU 330 may also host one or more low PHY layers, such as by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, and the like. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0069] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions, or low PHY layer functions (such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc.) based on functional splits (e.g., functional splits defined by 3GPP). In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of communicating with the control plane and user plane of the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0070] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0071] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0072] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0073] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The content described is different.

[0074] Figure 4 4 is a diagram illustrating an example 400 of using beams for communication between a network node and a UE according to the present disclosure. Figure 4 As shown, network node 110 and UE 120 may communicate with each other.

[0075] The network node 110 may transmit to a UE 120 located within the coverage area of ​​the network node 110. The network node 110 and the UE 120 may be configured for beamformed communications, wherein the network node 110 may transmit in the direction of the UE 120 using a directional NN transmit beam (e.g., a BS transmit beam), and the UE 120 may receive the transmission using a directional UE receive beam. Each NN transmit beam may have an associated beam identifier (ID), a beam direction or beam symbol, etc. The network node 110 may transmit downlink communications via one or more NN transmit beams 405.

[0076] UE 120 may attempt to receive downlink transmissions via one or more UE receive beams 410, which may be configured using different beamforming parameters at the receive circuitry of UE 120. UE 120 may identify a particular NN transmit beam 405 (shown as NN transmit beam 405-A) and a particular UE receive beam 410 (shown as UE receive beam 410-A) that provide relatively good performance (e.g., having the best channel quality of different measured combinations of NN transmit beams 405 and UE receive beams 410). In some examples, UE 120 may send an indication of which NN transmit beam 405 UE 120 identifies as a preferred NN transmit beam, and network node 110 may select the preferred NN transmit beam for transmissions to UE 120. Thus, UE 120 may obtain and maintain a beam pair link (BPL) for downlink communications with network node 110 (e.g., a combination of NN transmit beam 405-A and UE receive beam 410-A), which may be further refined and maintained according to one or more established beam refinement procedures.

[0077] A downlink beam (such as a NN transmit beam 405 or a UE receive beam 410) may be associated with a transmit configuration indication (TCI) state. The TCI state may indicate a directionality or characteristic of the downlink beam, such as one or more QCL attributes of the downlink beam. The QCL attributes may include, for example, Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, etc. In some examples, each NN transmit beam 405 may be associated with a synchronization signal block (SSB), and the UE 120 may indicate a preferred NN transmit beam 405 by transmitting an uplink transmission in the resources of the SSB associated with the preferred NN transmit beam 405. A specific SSB may have an associated TCI state (e.g., for an antenna port or for beamforming). In some examples, the network node 110 may indicate a downlink NN transmit beam 405 based at least in part on the antenna port QCL attributes that may be indicated by the TCI state. For different QCL types (e.g., QCL types for different combinations of Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, etc.), the TCI state may be associated with a set of downlink reference signals (e.g., SSB, and aperiodic, periodic, or semi-persistent channel state information reference signals (CSI-RS)). In the case where the QCL type indicates spatial reception parameters, the QCL type may correspond to simulated receive beamforming parameters of the UE receive beam 410 at the UE 120. Thus, the UE 120 may select the corresponding UE receive beam 410 from the BPL set based at least in part on the network node 110 indicating the NN transmit beam 405 via the TCI indication. For example, the TCI state information element may indicate a TCI state identifier (such as tci-StateID), a QCL type (such as qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, or qcl-TypeD), a cell identifier (such as ServCellIndex), a bandwidth part identifier (such as bwp-Id), or a reference signal identifier (such as NZP-CSI-RS-ResourceId or SSB-Index), and the like.

[0078] The network node 110 may maintain an activated TCI state set for downlink shared channel transmission and an activated TCI state set for downlink control channel transmission. The activated TCI state set for downlink shared channel transmission may correspond to a beam used by the network node 110 for downlink transmission on a physical downlink shared channel (PDSCH). The activated TCI state set for downlink control channel communication may correspond to a beam that the network node 110 may use for downlink transmission on a physical downlink control channel (PDCCH) or in a control resource set (CORESET). The UE 120 may also maintain the activated TCI state set for receiving downlink shared channel transmissions and CORESET transmissions. In the case where the TCI state is activated for the UE 120, the UE 120 may have one or more antenna configurations based at least in part on the TCI state, and the UE 120 may not need to reconfigure the antenna or antenna weighting configuration. In some examples, the activated TCI state set (eg, activated PDSCH TCI state and activated CORESET TCI state) for UE 120 may be configured via a configuration message, such as a radio resource control (RRC) message.

[0079] Similarly, for uplink communications, UE 120 may transmit in the direction of network node 110 using a directional UE transmit beam, and network node 110 may receive the transmission using a directional NN receive beam. Each UE transmit beam may have an associated beam ID, beam direction, or beam symbol, etc. UE 120 may transmit uplink communications via one or more UE transmit beams 415.

[0080] The network node 110 may receive uplink transmissions via one or more NN receive beams 420 (e.g., BS receive beams). The network node 110 may identify a specific UE transmit beam 415 (shown as UE transmit beam 415-A) and a specific NN receive beam 420 (shown as NN receive beam 420-A) that provide relatively good performance (e.g., having the best channel quality of different measured combinations of UE transmit beams 415 and NN receive beams 420). In some examples, the network node 110 may send an indication of which UE transmit beam 415 the network node 110 identifies as a preferred UE transmit beam, and the network node 110 may select the preferred UE transmit beam for transmissions from the UE 120. Thus, UE 120 and network node 110 may obtain and maintain a BPL for uplink communications (e.g., a combination of UE transmit beam 415-A and NN receive beam 420-A), which may be further refined and maintained according to one or more established beam refinement procedures. An uplink beam (such as UE transmit beam 415 or NN receive beam 420) may be associated with a spatial relationship. The spatial relationship may indicate a directionality or characteristic of the uplink beam (similar to one or more QCL attributes), as described above.

[0081] In some cases, in order to reduce signaling overhead, the uplink spatial relationship information may not be signaled to the UE 120. In such examples, the UE 120 may derive or determine the uplink spatial relationship information based on a default rule (e.g., a default beam rule). For example, the default rule may indicate that the UE 120 will derive or determine the uplink spatial relationship information based on a signal received via the CORESET with the lowest identifier in the active downlink bandwidth part (BWP). For example, the UE 120 may use the downlink TCI state associated with the CORESET as the source TCI state for deriving the uplink spatial relationship information. In some cases, the CORESET may be associated with two (or more) TCI states. In such examples, the UE 120 may use the first TCI state (e.g., the TCI state with the lowest identifier or index value) as the source TCI state for deriving the uplink spatial relationship information.

[0082] In a unified TCI framework, a network (e.g., network node 110) may support common TCI state ID updates and activations to provide common QCL information and / or common uplink transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication may be applied to intra-band CA as well as joint DL / UL beam indications and separate downlink / uplink beam indications. A common TCI state ID may mean that a reference signal (RS) determined according to a TCI state indicated by a common TCI state ID is used to provide a QCL type D indication and determine a UL transmit spatial filter across the set of configured CCs. In a unified TCI state framework, TCI states may be provided for downlink beams and uplink beams. In some cases, a joint uplink and downlink TCI state may be defined that indicates a common beam for both uplink and downlink communications. In some examples, separate TCI states may be defined for uplink and downlink communications, such as one or more uplink TCI states and one or more downlink TCI states.

[0083] Some networks may use different beam indication types to indicate one or more beams used for communication via a channel set. In some examples, the type of beam indication type may include a beam indication indicating that a common beam is used for multiple channels or that resources are used for reference signals; or the beam indication type includes a single beam indication indicating that a beam is used for a single channel or that resources are used for reference signals. As used herein, "unified TCI state indication" may refer to a TCI state indication using a unified TCI framework.

[0084] For example, a unified TCI state indication may include an indication of a TCI state that may be applied to multiple channels and / or reference signals. For example, in some cases, the TCI state may be used for downlink beam indication, and the spatial relationship may be used for uplink beam indication. Such beam indications may be referred to herein as "non-uniform beam indications". Non-uniform beam indications may be applied to one channel for one communication scheduled in the channel.

[0085] In some examples, the network node 110 and the UE 120 may use a unified TCI framework for both downlink beam indication and uplink beam indication. In the unified TCI framework, the TCI state indication may be used to indicate a joint downlink and uplink TCI state or to indicate a separate downlink TCI state and a separate uplink TCI state. Such a TCI state indication that may be used to indicate a joint downlink and uplink beam, a separate downlink beam, or a separate uplink beam is referred to herein as a "unified TCI state indication". The unified TCI state indication (e.g., a joint downlink and uplink TCI state indication and / or a separate downlink indication and a separate uplink TCI state indication) may be applied to multiple channels. For example, a unified TCI state indication for a joint uplink and downlink TCI state may be used to indicate a beam direction for one or more downlink channels (e.g., PDSCH and / or PDCCH) or reference signals (e.g., CSI-RS) and a beam direction for one or more uplink channels (e.g., physical uplink shared channel (PUSCH) and / or physical uplink control channel (PUCCH)) or reference signals (e.g., sounding reference signal (SRS)). A unified TCI state indication for a separate downlink TCI state may be used to indicate a beam direction for multiple downlink channels (e.g., PDSCH and PDCCH) or reference signals (e.g., CSI-RS). A unified TCI state indication for a separate uplink TCI state may be used to indicate a beam direction to be used for multiple uplink channels (e.g., PUSCH and PUCCH) or reference signals (e.g., SRS). In some examples, the unified TCI status indication can be "sticky" such that the indicated beam direction will be used for the channel and / or reference signal to which the TCI status indication applies until another indication is received.

[0086] In some examples, there may be two TCI state indication modes in the unified TCI state framework. The first mode may be a separate downlink and uplink TCI state indication mode, in which a separate downlink TCI state and a separate uplink TCI state are used to indicate the downlink beam direction and the uplink beam direction of the UE. For example, when the UE is having a maximum allowed exposure (MPE) problem, the separate downlink and uplink TCI state indication mode may be used to indicate the different beam directions of the UE for uplink beams (e.g., UE Tx beams) and downlink beams (e.g., UE Rx beams). The second mode may be a joint downlink and uplink TCI state indication mode, in which the TCI state indication is used to indicate the joint uplink and downlink beam directions to the UE. For example, when (as may be assumed in some examples) the UE has a channel correspondence between a downlink channel and an uplink channel, the joint downlink and uplink TCI state indication mode may be used, and the same beam direction may be used for both the uplink beam (e.g., UE Tx beam) and the downlink beam (e.g., UE Rx beam).

[0087] In some examples, in a unified TCI state framework, a downlink TCI state, an uplink TCI state, and / or a joint downlink and uplink TCI state may be configured for a UE via RRC signaling from a network node. A medium access control (MAC) control element (MAC-CE) sent from the network node to the UE may activate multiple RRC-configured TCI states and indicate a mapping of TCI field code points. In some examples, one TCI field code point may represent a joint downlink and uplink TCI state, and the TCI field code point may be used for a joint downlink and uplink beam indication. In some examples, one TCI field code point may represent a TCI state pair including a downlink TCI state and an uplink TCI state, and the TCI field code point may be used for separate downlink and uplink beam indications. In some examples, one TCI field code point may represent only a downlink TCI state, and the TCI field code point may be used for only a downlink beam indication. In some examples, one TCI field code point may indicate only the uplink TCI state, and the TCI field code point may be used for uplink-only beam indication. If the MAC-CE indicates a mapping to only a single TCI field code point, the MAC-CE may be used as the beam indication. In this case, the UE 120 may start applying the beam indication indicated in the MAC-CE within a specific duration (e.g., 3 ms) after sending a hybrid automatic repeat request acknowledgement (HARQ-ACK) to the network node 110 in response to the PDSCH communication carrying the MAC-CE.

[0088] If the MAC-CE indicates a mapping to more than one TCI field code point, a DCI including an indication of the TCI field code point may be used to provide a beam indication to the UE. For example, the UE 120 may receive a DCI including an indication of the TCI field code point (e.g., via PDCCH communication). The TCI field code point may be mapped to a unified TCI state indication, which may correspond to a joint downlink and uplink TCI state, a separate downlink and uplink TCI state pair, a downlink-only TCI state, or an uplink-only TCI state. In some examples, a downlink DCI (e.g., DCI format 1_1 / 1_2) may be used to provide a beam indication (e.g., an indication of a TCI field code point) regardless of whether there is a downlink assignment. The DCI including an indication of the TCI field code point may be referred to as a "beam indication DCI".

[0089] As indicated above, Figure 4 are provided as examples. Other examples can be found in Figure 4 The content described is different.

[0090] Figure 5 is a diagram illustrating an example 500 associated with SFN communications according to the present disclosure.

[0091] In some cases, the UE may operate in an SFN. An SFN may be a network configuration in which multiple cells (e.g., multiple network nodes or multiple cells associated with a single network node) simultaneously transmit the same signal through the same frequency channel. As used herein, "SFN transmission" may refer to two or more transmissions that are transmitted using the same (or substantially the same) time domain resources and frequency domain resources. For example, an SFN may be a broadcast network. An SFN may achieve an extended coverage area without using additional frequencies. For example, an SFN configuration may include multiple network nodes in an SFN area that use the same frequency to transmit one or more identical signals at the same or substantially the same time. In some aspects, an SFN configuration may include other network devices, such as multiple TRPs corresponding to the same network node. A TRP may include a network node 110, a DU, and / or a RU, and the like. Multiple TRPs may provide coverage for an SFN area. Multiple TRPs may use the same frequency to transmit one or more identical signals at the same or substantially the same time. In some examples, the same signal sent simultaneously by the multiple network nodes (and / or multiple TRPs) may include a PDSCH signal, a CORESET scheduling PDSCH and / or a reference signal (e.g., SSB, CSI-RS, tracking reference signal (TRS) or other reference signal), and so on.

[0092] One use case for SFNs may be in high mobility scenarios, such as high speed train scenarios. In such examples, UE 120 may be moving quickly (e.g., in a high speed train). TRPs may be deployed (e.g., along an expected path of UE 120, such as along the tracks of a high speed train) to provide coverage of the SFN area. The TRPs may simultaneously send SFN communications to UE 120. Thus, the likelihood that UE 120 can successfully receive SFN communications in high mobility scenarios is increased (e.g., because multiple TRPs may be sending SFN communications, as described elsewhere herein).

[0093] As indicated by reference numeral 505, an example of communications without using an SFN configuration is depicted. The TRP 510 may use a transmit (Tx) beam to transmit communications to the UE 120. The transmit beam may be associated with a TCI state. The UE 120 may use a receive (Rx) beam to receive communications (e.g., transmitted by the TRP 510). For example, the UE 120 may identify the TCI state associated with the transmit beam and may use information provided by the TCI state to receive communications.

[0094] As shown at reference numeral 515, an example of a first SFN pattern is depicted. Figure 5 As shown, the first TRP 520 (or the first network node 110) and the second TRP 525 (or the second network node 110) can send SFN communications 530 to the UE 120. For example, the first TRP 520 and the second TRP 525 can use the same frequency domain resources and the same time domain resources to send substantially the same information (e.g., SFN communications 530) to the UE 120. The first TRP 520 can use a first transmit beam to send the SFN communications 530. The second TRP 525 can use a second transmit beam to send the SFN communications 530. In this first SFN mode, the UE 120 may not be aware that the SFN communications 530 are sent on separate transmit beams (e.g., from different TRPs and / or different network nodes 110). Thus, when multiple network nodes (and / or multiple TRPs) simultaneously transmit the same signal to UE 120, the SFN configuration may be transparent to UE 120, and UE 120 may aggregate or accumulate simultaneous signal transmissions from the multiple TRPs (and / or multiple network nodes 110), which may provide higher signal quality or higher tolerance to multipath fading, among other benefits. For example, UE 120 may receive SFN communications 530 using a single receive beam (e.g., SFN communications 530 may be received using a single spatial receive direction, etc.). In other words, the TCI states of different transmit beams used to transmit SFN communications 530 may not be signaled to UE 120.

[0095] As shown at reference numeral 535, an example of a second SFN pattern is depicted. Figure 5 As shown, the first TRP 540 (or the first network node 110) and the second TRP 545 (or the second network node 110) can send SFN communication 550 to the UE 120. For example, the first TRP 540 and the second TRP 545 can use the same frequency domain resources and the same time domain resources to send substantially the same information (e.g., SFN communication 550) to the UE 120. The first TRP 540 can use a first transmit beam to send SFN communication 550. The second TRP 545 can use a second transmit beam to send SFN communication 550. In this second SFN mode, the UE 120 can be aware that the SFN communication 550 is sent on a separate transmit beam (e.g., from a different TRP and / or a different network node 110). For example, a first TCI state of a first transmit beam (e.g., associated with the first TRP 540) and a second TCI state of a second transmit beam (e.g., associated with the second TRP 545) can be signaled to the UE 120. For example, the network node 110 may send configuration information (e.g., directly to the UE 120 or via one or more network nodes) indicating that the SFN communication 550 may be a combination of transmissions from different TRPs and / or different transmission beams. The UE 120 may use information associated with the different TRPs and / or different transmission beams (e.g., the first TCI state and the second TCI state) to improve reception performance of the SFN communication 550. For example, Figure 5 As shown, UE 120 may receive SFN communications 550 using different spatial directions (e.g., different receive beams) based at least in part on the TCI state of the transmit beam associated with SFN communications 550. This may improve performance of UE 120 because UE 120 may receive SFN communications 550 with improved signal strength and / or signal quality, etc., from different transmit beams and / or different TRPs.

[0096] As indicated above, Figure 5 are provided as examples. Other examples can be found in Figure 5 The content described is different.

[0097] Figure 6 is a diagram illustrating an example 600 associated with SFN scheme indication and SFN TCI state activation according to the present disclosure.

[0098] PDCCH or PDSCH (PDCCH / PDSCH) transmissions associated with multiple TRP scenarios may be based at least in part on SFN transmissions. The same PDCCH / PDSCH transmission may be sent simultaneously from two TRPs using the same time and frequency resources, which may improve PDCCH / PDSCH reliability (for example, in high-speed UE mobility or signal blocking scenarios). In some cases, the PDCCH transmission mode may not be the same as the PDSCH transmission mode, where PDCCH transmissions may be carried from a single TRP and PDSCH transmissions may be carried from two TRPs in an SFN manner; or PDCCH transmissions may be carried from two TRPs in an SFN manner and PDSCH transmissions may be carried from a single TRP.

[0099] As indicated by reference numeral 605, the network node 110 may send configuration information and the UE 120 may receive the configuration information. For example, the configuration information may include an RRC configuration. In some examples, the SFN transmission scheme may be identified by an RRC higher layer parameter, which may indicate that PDCCH / PDSCH transmissions may be sent from two TRPs in SFN mode.

[0100] The two SFN transmission schemes may include a first SFN transmission scheme (sfnSchemeA) and a second SFN transmission scheme (sfnSchemeB). In the first SFN transmission scheme (e.g., sfnSchemeA), PDCCH / DMRS (or PDSCH / DMRS) transmission may be transmitted in an SFN manner (e.g., the same PDCCH from each TRP to achieve diversity). The DMRS transmitted by the PDCCH may be associated with two TCI states to enhance Doppler shift tracking and enable multi-beam reception of PDCCH transmission to enhance reliability. In the first SFN transmission scheme (e.g., sfnSchemeA), the first TCI state may be associated with QCL type A and QCL type D, and the second TCI state may be associated with QCL type A and QCL type D, wherein QCL type A may be associated with Doppler shift, Doppler spread, delay spread, and average delay.

[0101] In this second SFN transmission scheme (e.g., sfnSchemeB), PDCCH / DMRS (or PDSCH / DMRS) transmissions may be transmitted in a SFN manner. However, the PDCCH transmission of the first TRP may be frequency pre-compensated to align in frequency with the second PDCCH transmission of the second TRP. The TRP-based pre-compensation may be based at least in part on differential Doppler shift. The DMRS transmitted by the PDCCH may be linked to two TCI states, enabling multi-beam reception of the PDCCH transmission to enhance reliability. In this second SFN transmission scheme, the first TCI state may be associated with QCL type A and QCL type D, and the second TCI state may be associated with a new QCL type (which may be associated with average delay and delay spread) and QCL type D.

[0102] As shown by reference numeral 610, for PDCCH transmission, the CORESET may be activated with two TCI states via a MAC-CE activation command. For PDSCH transmission, the MAC-CE may indicate one or more TCI code points. A TCI code point may be associated with two (or more) TCI states. As shown by reference numeral 610, for PDSCH transmission, the network node 110 may send a DCI communication, and the UE 120 may receive the DCI communication. The DCI may indicate a TCI code point. For example, DCI formats 1_1 and 1_2 may indicate a code point with two TCI states.

[0103] As indicated by reference numeral 625, the network node 110 may transmit one or more SFN communications (e.g., PDCCH transmissions and / or PDSCH transmissions), and the UE 120 may receive one or more SFN communications (e.g., PDCCH transmissions and / or PDSCH transmissions). The UE 120 may receive the one or more SFN communications using information associated with the SFN scheme (e.g., indicated by configuration information) and the downlink SFN TCI state (e.g., indicated by MAC-CE and / or DCI). For example, the downlink SFN TCI state may include two (or more) TCI states. A first TCI state included in the downlink SFN TCI state may be associated with a first TRP (e.g., a first RU, a first network node, or a first base station), and a second TCI state included in the downlink SFN TCI state may be associated with a second TRP (e.g., a second RU, a second network node, or a second base station).

[0104] As indicated above, Figure 6 are provided as examples. Other examples can be found in Figure 6 The content described is different.

[0105] As described above, in some cases, the network (e.g., one or more network nodes 110) may use a unified TCI framework to indicate the TCI state to the UE 120. However, the unified TCI framework may generally be applied in a single TRP scenario. In some examples, the unified TCI framework may be extended to multiple TRP scenarios. For example, a TCI code point may be mapped to two TCI states, each of which is associated with a CORESET pool index. The unified TCI framework is extended to SFN scenarios so that beam indications using the unified TCI framework may update or indicate downlink SFN TCI states (e.g., two or more TCI states) for multiple downlink channels and / or multiple reference signals. However, SFN operations may be supported only for the downlink (e.g., not for the uplink) (e.g., by the UE 120). Therefore, uplink spatial relationship information and / or uplink TCI states may not be utilized to indicate some uplink resources, uplink channels, and / or uplink reference signals.

[0106] However, because the unified TCI framework is extendable to SFN scenarios, multiple TCI states (e.g., for multiple channels or reference signals) may be indicated, configured, and / or activated by the unified TCI framework. Therefore, (e.g., when the beam indication using the unified TCI framework does not indicate spatial relationship information) the UE 120 may not know which signals or TCI states will be used to derive uplink parameters or uplink spatial relationship information. In other words, the beam indication using the unified TCI framework may indicate multiple (e.g., two or more) TCI states, which are to be applied to one or more downlink channels and / or reference signals for SFN operation. However, in such scenarios, rules or procedures indicating how the UE 120 is to derive uplink parameters or uplink spatial relationship information (e.g., indicating which TCI state of the multiple TCI states and / or which downlink channel of the downlink channels will be used to derive the uplink parameters) may not be defined.

[0107] Some techniques and apparatus described herein enable uplink transmission parameter selection (e.g., uplink TCI state) in a unified TCI state framework. For example, a UE 120 may receive a beam indication associated with a unified TCI state indication. The unified TCI state indication may include an indication of one or more downlink SFN TCI states. A downlink SFNTCI state (e.g., SFN TCI code point) may include two or more TCI states (e.g., associated with downlink SFN operation). The UE 120 may use the uplink TCI state (and / or uplink spatial relationship information) to send uplink communications using uplink resources that are not associated with the unified TCI state indication (e.g., not indicated by the unified TCI state indication). One or more parameters associated with the uplink TCI state may be based at least in part on the unified TCI state indication (e.g., may be based at least in part on the TCI state included in the downlink SFN TCI state) or may be based at least in part on another TCI state indication signal.

[0108] For example, UE 120 may use configuration information including other TCI state indication signals (e.g., where the other TCI state indication signals include uplink spatial relationship information, and the one or more parameters associated with the uplink TCI state are based at least in part on the uplink spatial relationship information). For another example, UE 120 may use one of the TCI states associated with the downlink SFN TCI state to derive the one or more parameters associated with the uplink TCI state. In some aspects, UE 120 may use a first TCI state of the two or more TCI states associated with the downlink SFN TCI state to derive the one or more parameters (e.g., a TCI state associated with a lowest index value or a highest index value of the index values ​​of the two or more TCI states may be used). For another example, UE 120 may receive an indication (e.g., in a beam indication or a unified TCI state indication) of the TCI state to be used to derive the one or more parameters. In some aspects, UE 120 may derive the one or more parameters based on a TCI state associated with a last monitored CORESET (eg, a last monitored SFN CORESET or a last monitored non-SFN CORESET).

[0109] Thus, rules or procedures may be defined to indicate how the UE 120 is to derive uplink parameters for an uplink TCI state when the UE 120 receives a unified TCI state indication. Thus, the UE 120 may be enabled to determine uplink parameters and / or uplink TCI states for sending uplink communications (e.g., not indicated by the unified TCI state indication). This may improve communication performance of the UE 120 by ensuring that the UE 120 is using the correct information or TCI state to determine or derive the uplink parameters associated with the uplink TCI state.

[0110] Figure 7 is a diagram illustrating an example 700 associated with an uplink TCI state in a unified TCI state according to the present disclosure. Figure 7 As shown, one or more network nodes 110 (e.g., network node 110, CU, DU, and / or RU) may communicate with UE 120. In some aspects, network node 110 and UE 120 may be part of a wireless network (e.g., wireless network 100). UE 120 and network node 110 may be part of a wireless network (e.g., wireless network 100). Figure 7 The operations shown have previously established a wireless connection. In some aspects, UE 120 and network node 110 may (e.g., in conjunction with Figure 5 and Figure 6 Communicate using SFN transmission and / or SFN scheme) in a manner similar to that described.

[0111] In some aspects, actions described as being performed by network node 110 may be performed by multiple different network nodes. For example, a configuration action may be performed by a first network node (e.g., CU or DU), and a radio communication action may be performed by a second network node (e.g., DU or RU).

[0112] As used herein, "sending" a communication from a network node 110 to a UE 120 may refer to direct sending (e.g., from the network node 110 to the UE 120), or indirect sending via one or more other network nodes or devices. For example, if the network node 110 is a DU, indirect sending to the UE 120 may include the DU sending the communication to the RU and the RU sending the communication to the UE 120. Similarly, "sending" a communication from the UE 120 to the network node 110 may refer to direct sending (e.g., from the UE 120 to the network node 110), or indirect sending via one or more other network nodes or devices. For example, if the network node 110 is a DU, indirect sending to the network node 110 may include the UE 120 sending the communication to the RU and the RU sending the communication to the DU.

[0113] As indicated by reference numeral 705, the network node 110 may send configuration information and the UE 120 may receive the configuration information. In some aspects, the UE 120 may receive the configuration information via one or more of system information (SI) signaling, RRC signaling, one or more MAC-CEs and / or DCIs, etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for selection by the UE 120 (e.g., stored by the UE 120 and / or previously indicated by the network node 110 or another network device) and / or explicit configuration information for the UE 120 to configure itself, etc.

[0114] In some aspects, the configuration information may indicate a configuration for one or more downlink channels (e.g., PDCCH and / or PDSCH). In some aspects, the configuration information may include an SFN configuration. In some aspects, a given downlink channel configuration and / or reference signal configuration (e.g., SSB configuration and / or CSI-RS configuration) may indicate an SFN configuration associated with the given downlink channel configuration and / or reference signal configuration.

[0115] In some aspects, the configuration information may indicate that SFN operation is enabled for the UE 120. For example, for a given BWP, the configuration information may indicate that SFN operation is enabled for the UE 120 when communicating using the given BWP. For example, an RRC parameter (e.g., a higher layer parameter) may indicate whether SFN operation is enabled for a given BWP. In some aspects, the configuration information may indicate whether a downlink channel, a reference signal, and / or a CORESET, etc., is configured for SFN operation. For example, an RRC parameter may indicate whether the downlink channel, a reference signal, and / or a CORESET, etc., is configured for SFN operation.

[0116] In some aspects, the configuration information may indicate an SFN scheme to be applied by UE 120 (e.g., a first SFN transmission scheme (sfnSchemeA) or a second SFN transmission scheme (sfnSchemeB)). For example, for a given downlink channel or reference signal, the configuration information may indicate an SFN scheme to be associated with the given downlink channel or reference signal (e.g., the first SFN transmission scheme (sfnSchemeA) or the second SFN transmission scheme (sfnSchemeB)). In some aspects, the configuration information may indicate that multiple SFN schemes are enabled for a given downlink channel or reference signal (e.g., both the first SFN transmission scheme (sfnSchemeA) and the second SFN transmission scheme (sfnSchemeB)). In other aspects, the configuration information may indicate that SFN is not enabled for one or more downlink channels and / or reference signals. The configuration information may configure one or more SFN schemes for one or more downlink channels and / or reference signals configured for UE 120.

[0117] In some aspects, the configuration information may indicate that in a scenario where the UE 120 receives a beam indication (e.g., which uses a unified TCI state framework) including an indication of one or more downlink SFN TCI states, the UE 120 will derive one or more uplink parameters for an uplink TCI state. In some aspects, the configuration information may include a TCI state indication signal. The TCI state indication signal may include uplink spatial relationship information. For example, the one or more parameters associated with the uplink TCI state (e.g., to be used by the UE 120) may be based at least in part on the uplink spatial relationship information. In other words, the UE 120 may use the spatial relationship information to update signaling and / or configuration of uplink resources that are not indicated by or associated with a beam indication (e.g., which uses a unified TCI state framework) including an indication of one or more downlink SFN TCI states.

[0118] In some aspects, the configuration information may indicate that the UE 120 is to use the TCI state associated with the CORESET to derive one or more uplink parameters for an uplink TCI state (e.g., for uplink resources not indicated by a beam indication (e.g., which uses a unified TCI state architecture) or not associated with the beam indication, the beam indication including an indication of one or more downlink SFN TCI states). For example, the configuration information may indicate that the UE 120 is to derive the one or more uplink parameters using the first TCI state of the lowest ID CORESET in the most recently monitored timeslot. In some aspects, the configuration information may indicate that the CORESET will be a CORESET associated with a given type. For example, the type may include a SFNCORESET (e.g., a CORESET configured with SFN operation enabled) or a non-SFN CORESET (e.g., a CORESET not configured with SFN operation enabled or configured with SFN operation disabled). For example, the configuration information may indicate that the UE 120 will use the first TCI state of the lowest ID SFN CORESET in the latest monitored timeslot to derive the one or more uplink parameters. For another example, the configuration information may indicate that the UE 120 will use the first TCI state of the lowest ID non-SFN CORESET in the latest monitored timeslot to derive the one or more uplink parameters.

[0119] In some aspects, as shown by reference numeral 710, the network node 110 may send and the UE 120 may receive an indication of a TCI code point indicating two or more TCI states associated with a SFN scheme (e.g., a SFN transmission scheme). For example, the UE 120 may receive an indication of a downlink SFN TCI state (e.g., which includes two or more downlink TCI states). For example, the UE 120 may receive a MAC-CE indicating one or more TCI code points. The TCI code point for the SFN scheme may be associated with or mapped to two or more TCI states. For example, the UE 120 may receive a MAC-CE indicating multiple activated TCI code points. The TCI code point may be triggered via a DCI (e.g., a beam indication DCI). In other words, the MAC-CE may activate one or more TCI code points for SFN operation.

[0120] In some aspects, the UE 120 may receive a MAC-CE indicating that a CORESET is associated with two or more TCI states (e.g., a MAC-CE activating a CORESET with two or more TCI states). This may indicate that the CORESET (e.g., and the PDCCH) is associated with SFN operation because the CORESET has two (or more) activated TCI states (e.g., it may be referred to herein as an SFN CORESET). A CORESET with one (e.g., a single) activated TCI state may be referred to herein as a non-SFN CORESET. In some aspects, the CORESET TCI activation may be applicable to all component carriers associated with the UE 120 (e.g., configured for the UE). In some aspects, the UE 120 may not expect to be configured with different SFN schemes for different CORESETs within a given component carrier. In some aspects, if the CORESET is not configured with an SFN scheme through RRC, the UE 120 may not expect to receive a MAC-CE indicating two or more TCI states for the CORESET.

[0121] As indicated by reference numeral 715, the network node 110 may send a beam indication, and the UE 120 may receive the beam indication. The beam indication may be included in the DCI. For example, the beam indication may be a beam indication DCI. In some aspects, the beam indication may be associated with a unified TCI state indication (e.g., may be associated with a unified TCI framework). For example, the beam indication may include an indication of one or more TCI states applicable to multiple channels and / or reference signals. In some aspects, the beam indication may include an indication of one or more TCI states applicable to SFN operation (e.g., may indicate a downlink SFN TCI state or SFN TCI code point to be applied to one or more channels and / or reference signals). For example, the beam indication may be associated with a unified TCI state indication and may include an indication of one or more downlink SFN TCI states. Additionally, the beam indication may indicate one or more channels and / or reference signals associated with the beam indication.

[0122] In some examples, UE 120 may be associated with or configured with uplink resources not indicated by the beam indication. In some aspects, the uplink resources may be associated with a dynamic grant, a configuration grant, and / or a dedicated uplink control channel resource (e.g., a dedicated PUCCH resource), etc. For example, the uplink resources may include PUSCH resources, PUCCH resources, SRS resources, and / or SRS resource sets, etc.

[0123] As shown by reference numeral 720, UE 120 may determine one or more uplink parameters for an uplink TCI state that will be used to send uplink communications using the uplink resources not indicated by the beam indication. The one or more uplink parameters may include parameters used by UE 120 to determine transmit power, spatial direction, beam, and / or other information for sending uplink communications. For example, the one or more parameters may include power control information (e.g., power control settings, closed-loop power control parameters, and / or open-loop power control parameters), a source TCI state (e.g., a TCI state that will be used to derive the one or more uplink parameters), a source QCL signal (e.g., a signal that will be used to derive QCL information), a source path loss reference signal, and / or spatial relationship information, and the like.

[0124] In some aspects, the one or more uplink parameters may be based at least in part on another TCI state indication signal (e.g., different from the beam indication). For example, in some aspects, the UE 120 may receive and the network node 110 may send the configuration information including the other TCI state indication signal. The other TCI state indication signal may include uplink spatial relationship information. The one or more parameters associated with the uplink TCI state may be based at least in part on the uplink spatial relationship information (e.g., indicated by the configuration information).

[0125] In some aspects, the UE 120 may monitor a CORESET using the TCI state associated with the other TCI state indication signal. The CORESET may be associated with a lowest index value among the index values ​​of the CORESET monitored by the UE 120 in a given time slot. The UE 120 may determine the one or more parameters associated with the uplink TCI state based at least in part on the TCI state (e.g., for monitoring the CORESET). In other words, the UE 120 may derive the one or more uplink parameters using the TCI state of the lowest ID CORESET in the most recently monitored time slot (e.g., the first TCI state). If the CORESET is associated with multiple TCI states, the UE 120 may use the first TCI state among the multiple TCI states (e.g., as indicated by the index values ​​or identifiers of the multiple TCI states). For example, the UE 120 may derive the one or more uplink parameters using the TCI state associated with the lowest or highest identifier among the multiple TCI states.

[0126] In some aspects, the CORESET may be the last monitored CORESET associated with a type of CORESET. The type may be indicated by configuration information and / or defined or otherwise determined by a wireless communication standard (e.g., 3GPP). For example, the type of CORESET may be a SFN CORESET or a non-SFN CORESET. In other words, the UE 120 may derive the one or more uplink parameters using the TCI state (e.g., the first TCI state) for monitoring the SFN CORESET in the last monitoring timeslot. Alternatively, the UE 120 may derive the one or more uplink parameters using the TCI state (e.g., the first TCI state) for monitoring the non-SFNCORESET in the last monitoring timeslot. The "last monitoring timeslot" may refer to the (e.g., in time) most recent timeslot in which the UE 120 monitored a CORESET (e.g., a CORESET associated with the type).

[0127] In some aspects, the UE 120 may use a TCI state associated with a downlink SFN TCI state (e.g., an SFN TCI code point) to derive the one or more uplink parameters. For example, the UE 120 may use QCL information, spatial direction, and / or power control information associated with the TCI state to determine the one or more uplink parameters associated with the uplink TCI state. For example, the UE 120 may determine an antenna mode and / or beam to be used for transmission using uplink resources based at least in part on the TCI state (e.g., beam) associated with the downlink SFN TCI state. In other words, the one or more parameters associated with the uplink TCI state may be based at least in part on a downlink TCI state in the one or more downlink SFN TCI states.

[0128] As described above, a downlink SFN TCI state may be associated with two or more downlink TCI states. For example, each downlink SFN TCI code point may include two or more TCI states. In some aspects, there may be an indication of which TCI state of the two or more TCI states associated with the indicated downlink SFN TCI state will be used to derive the uplink TCI state. In some aspects, the downlink TCI state associated with the one or more downlink SFN TCI states may be associated with a corresponding index value or identifier. The downlink TCI state (e.g., to be used by UE 120 to derive the one or more uplink parameters) may be associated with the lowest index value or the highest index value in the corresponding index value. In other words, UE 120 may derive the one or more uplink parameters using the first TCI state in the indicated downlink SFN TCI state (e.g., indicated by the beam indication).

[0129] In some aspects, UE 120 may receive an indication that the downlink TCI state is to be used to derive the one or more parameters. For example, a beam indication (e.g., DCI) may include an indication of which of two or more TCI states associated with the downlink SFN TCI state the UE 120 is to use to derive the uplink TCI state and / or the uplink parameters associated with the uplink TCI state. For another example, an indication of the downlink SFN TCI state and / or SFN TCI code point (e.g., such as a MAC-CE similar to the MAC-CE described above in conjunction with reference numeral 710) may include an indication of which of two or more TCI states associated with the downlink SFN TCI state the UE 120 is to use to derive the uplink TCI state and / or the uplink parameters associated with the uplink TCI state. As another example, the configuration information may include an indication of which of the two or more TCI states associated with the downlink SFN TCI state the UE 120 will use to derive the uplink TCI state and / or the uplink parameter associated with the uplink TCI state. In some aspects, the UE 120 may not receive an indication of which of the two or more TCI states associated with the downlink SFN TCI state the UE 120 will use to derive the uplink TCI state and / or the uplink parameter associated with the uplink TCI state. Instead, which of the two or more TCI states associated with the downlink SFN TCI state the UE 120 will use may be defined or otherwise determined by a wireless communication standard (such as 3GPP).

[0130] UE 120 may determine the one or more uplink parameters using the TCI state or other signaling (e.g., as described in more detail above). Based at least in part on determining the one or more uplink parameters, UE 120 may derive or determine an uplink TCI state or spatial relationship to be used when transmitting via the uplink resource (e.g., not indicated by a beam indication).

[0131] As shown by reference numeral 725, the UE 120 may use the uplink TCI state to send an uplink communication, and the network node 110 may use the uplink TCI state to receive the uplink communication. For example, the uplink communication may be a PUCCH communication, a PUSCH communication, an SRS communication, a dynamic grant communication, and / or a configuration grant communication, etc. The UE 120 may use the one or more uplink parameters (e.g., derived and / or determined by the UE 120 as described above) to send the uplink communication. For example, the UE 120 may use power control information, spatial relationship information, and / or uplink beams (e.g., derived and / or determined by the UE 120 as described above), etc. to send the uplink communication.

[0132] Thus, rules or procedures may be defined to indicate how the UE 120 is to derive uplink parameters for an uplink TCI state when the UE 120 receives a unified TCI state indication. Thus, the UE 120 may be enabled to determine uplink parameters and / or uplink TCI states for sending uplink communications (e.g., not indicated by the unified TCI state indication). This may improve communication performance of the UE 120 by ensuring that the UE 120 is using the correct information or TCI state to determine or derive the uplink parameters associated with the uplink TCI state.

[0133] As indicated above, Figure 7 are provided as examples. Other examples can be found in Figure 7 The content described is different.
