COMMUNICATION METHOD, USER EQUIPMENT AND NETWORK NODE
[0001] The present disclosure relates to the technical field of wireless communications, and in particular to a communication method, a user equipment (UE) and a network node.
[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz, but also in "Above 6GHz" bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.
[0003] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.
[0004] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.
[0005] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.
[0006] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.
[0007] Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.
[0008] Considering the development of wireless communication from generation to generation, the technologies have been developed mainly for services targeting humans, such as voice calls, multimedia services, and data services. Following the commercialization of 5th-generation (5G) communication systems, it is expected that the number of connected devices will exponentially grow. Increasingly, these will be connected to communication networks. Examples of connected things may include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machines, and factory equipment. Mobile devices are expected to evolve in various form-factors, such as augmented reality glasses, virtual reality headsets, and hologram devices. In order to provide various services by connecting hundreds of billions of devices and things in the 6th-generation (6G) era, there have been ongoing efforts to develop improved 6G communication systems.
[0009] 6G communication systems, which are expected to be commercialized around 2030, have various significantly improved metrics compared to the current 5G communication systems. The peak data rate will reach at least 50 Gbit / s, and the user experienced data rate will reach at least 300 Mbit / s, the air-interface latency will be less than 1 ms, and the air-interface reliability will reach . In addition to the above basic communication metrics, the 6G communication systems will also have sensing capabilities, AI-related capabilities, better security, better interoperability and better sustainability.
[0010] In order for the 6G communication systems to fulfill the above metrics, more advanced air-interface technologies and network technologies need to be developed. The evolution of extreme Multiple Input Multiple Output (extreme MIMO) has been already under consideration, including the use of ultra-large scale antenna arrays, the development and evolution of distributed antenna systems, and the design of MIMO air-interface algorithms assisted by Artificial Intelligence (AI). This technology enables higher spectral efficiency, greater coverage, and precise localization and sensing capabilities. Additionally, for technologies that contribute to improve high-frequency band coverage, including metamaterial-based lenses and antennas, new antenna architectures, and reconfigurable intelligent surface (RIS), etc., they also need to be better evolved and developed.
[0011] In order to meet some of newly added functions of the 6G communication systems, new technologies need to be developed in the terms of network energy saving, air-interface security, and network security, meanwhile the feasibility of fusion technologies such as Integrated Sensing and Communication, needs to be studied.
[0012] Moreover, in order to improve the spectral efficiency and the overall network performances, the following technologies have been developed for 6G communication systems: a full-duplex technology for enabling an uplink transmission and a downlink transmission to simultaneously use the same frequency resource at the same time; a network technology for utilizing satellites, high-altitude platform stations (HAPS), and the like in an integrated manner; an improved network structure for supporting mobile base stations and the like and enabling network operation optimization and automation and the like; a dynamic spectrum sharing technology via collision avoidance based on a prediction of spectrum usage; an use of artificial intelligence (AI) in wireless communication for improvement of overall network operation by utilizing AI from a designing phase for developing 6G and internalizing end-to-end AI support functions; and a next-generation distributed computing technology for overcoming the limit of user equipment (UE) computing ability through reachable super-high-performance communication and computing resources (such as mobile edge computing (MEC), clouds, and the like) over the network. In addition, through designing new protocols to be used in 6G communication systems, developing mechanisms for implementing a hardware-based security environment and safe use of data, and developing technologies for maintaining privacy, attempts to strengthen the connectivity between devices, optimize the network, promote softwarization of network entities, and increase the openness of wireless communications are continuing.
[0013] It is expected that research and development of 6G communication systems in hyper-connectivity, including person to machine (P2M) as well as machine to machine (M2M), will allow the next hyper-connected experience. Particularly, it is expected that services such as truly immersive extended reality (XR), high-fidelity mobile hologram, and digital replica could be provided through 6G communication systems. In addition, services such as remote surgery for security and reliability enhancement, industrial automation, and emergency response will be provided through the 6G communication system such that the technologies could be applied in various fields such as industry, medical care, automobiles, and home appliances.

[0289] FIGS. 1-3 below describe various embodiments of the present disclosure implemented in wireless communications systems. The descriptions of FIGS. 1-3 are not meant to imply physical or architectural limitations to the manner in which different embodiments may be implemented. Different embodiments of the present disclosure may be implemented in any suitably-arranged communications system.
[0290] FIG. 1 illustrates an example wireless network according to embodiments of the present disclosure. The embodiment of the wireless network shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 could be used without departing from the scope of the present disclosure.
[0291] As shown in FIG. 1, the wireless network includes a base station (next generation nodeB, gNB or gNodeB) 101, a gNB 102, and a gNB 103. The gNB 101 communicates with the gNB 102 and the gNB 103. The gNB 101 also communicates with at least one network 130, such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.
[0292] The gNB 102 provides wireless broadband access to the network 130 for a first plurality of user equipments (UEs) within a coverage area 120 of the gNB 102. The first plurality of UEs includes a UE 111, which may be located in a small business; a UE 112, which may be located in an enterprise (E); a UE 113, which may be located in a WiFi hotspot (HS); a UE 114, which may be located in a first residence (R1); a UE 115, which may be located in a second residence (R2); and a UE 116, which may be a mobile device (M), such as a cell phone, a wireless laptop, a wireless personal digital assistant (PDA), or the like. The gNB 103 provides wireless broadband access to the network 130 for a second plurality of UEs within a coverage area 125 of the gNB 103. The second plurality of UEs includes the UE 115 and the UE 116, as well as subscriber stations (SS, for example, UEs) 117, 118 and 119. In some embodiments, one or more of the gNBs 101-103 may communicate with each other and with the UEs 111-116 using existing wireless communication techniques, and one or more of the UE 111-119 may communicate directly with each other (e.g., UEs 117-119) using other existing or proposed wireless communication techniques.
[0293] Depending on the network type, the term "base station" or "BS" can refer to any component (or collection of components) configured to provide wireless access to a network, such as transmit point (TP), transmit-receive point (TRP), an enhanced (or "evolved") base station (eNodeB or eNB), a 5G base station (gNB), a macrocell, a femtocell, a wireless fidelity (WiFi) access point (AP), or other wirelessly enabled devices. Base stations may provide wireless access in accordance with one or more wireless communication protocols, e.g., 3GPP 5G New Radio (NR), Long Term Evolution (LTE), LTE Advanced (LTE-A), high speed packet access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For the sake of convenience, the various names for a base station-type apparatus and functionality are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, the term "user equipment" (UE) can refer to any component such as a mobile station (MS), subscriber station (SS), remote terminal, wireless terminal, receive point, or user device. For the sake of convenience, the various names for a user equipment-type device and functionality are used interchangeably in this patent document to refer to remote wireless equipment that wirelessly accesses a BS, whether the UE is a mobile device (such as a mobile telephone or smartphone) or is normally considered a stationary device (such as a desktop computer or vending machine).
[0294] Dotted lines show the approximate extents of the coverage areas 120 and 125, which are shown as approximately circular for the purposes of illustration and explanation only. It should be clearly understood that the coverage areas associated with gNBs, such as the coverage areas 120 and 125, may have other shapes, including irregular shapes, depending upon the configuration of the gNBs and variations in the radio environment associated with natural and man-made obstructions.
[0295] As described in more detail below, one or more of the UEs 111-119 include circuitry, programing, or a combination thereof. In certain embodiments, and one or more of the gNBs 101-103 includes circuitry, programing, or a combination thereof.
[0296] Although FIG. 1 illustrates one example of a wireless network, various changes may be made to FIG. 1. For example, the wireless network could include any number of gNBs and any number of UEs in any suitable arrangement. Also, the gNB 101 could communicate directly with any number of UEs and provide those UEs with wireless broadband access to the network 130. Similarly, each gNB 102-103 could communicate directly with the network 130 and provide UEs with direct wireless broadband access to the network 130. Further, the gNBs 101, 102, and / or 103 could provide access to other or additional external networks, such as external telephone networks or other types of data networks.
[0297] FIG. 2 illustrates an example base station according to embodiments of the present disclosure. The embodiment of the gNB 102 illustrated in FIG. 2 is for illustration only, and the gNBs 101 and 103 of FIG. 1 could have the same or similar configuration. However, gNBs come in a wide variety of configurations, and FIG. 2 does not limit the scope of the present disclosure to any particular implementation of a gNB.
[0298] As shown in FIG. 2, the gNB 102 includes multiple antennas 200a-200n, multiple radio frequency (RF) transceivers 201a-201n, transmit (TX) processing circuitry 203, and receive (RX) processing circuitry 204. The gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface 207.
[0299] The RF transceivers 201a-201n receive, from the antennas 200a-200n, incoming RF signals, such as signals transmitted by UEs in the network 100. The RF transceivers 201a-201n down-convert the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 204, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 204 transmits the processed baseband signals to the controller / processor 205 for further processing.
[0300] The TX processing circuitry 203 receives analog or digital data (such as voice data, web data, electronic mail, or interactive video game data) from the controller / processor 205. The TX processing circuitry 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. The RF transceivers 201a-201n receive the outgoing processed baseband or IF signals from the TX processing circuitry 203 and up-converts the baseband or IF signals to RF signals that are transmitted via the antennas 201a-201n.
[0301] The controller / processor 205 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 205 could control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceivers 201a-201n, the RX processing circuitry 204, and the TX processing circuitry 203 in accordance with well-known principles. The controller / processor 205 could support additional functions as well, such as more advanced wireless communication functions.
[0302] For instance, the controller / processor 205 could support beam forming or directional routing operations in which outgoing signals from multiple antennas 200a-200n are weighted differently to effectively steer the outgoing signals in a desired direction. Any of a wide variety of other functions could be supported in the gNB 102 by the controller / processor 205.
[0303] The controller / processor 205 is also capable of executing programs and other processes resident in the memory 206, such as an operating system (OS). The controller / processor 205 can move data into or out of the memory 206 as required by an executing process.
[0304] The controller / processor 205 is also coupled to the backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems over a backhaul connection or over a network. The interface 207 could support communications over any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as one supporting 5G, LTE, or LTE-A), the interface 207 could allow the gNB 102 to communicate with other gNBs over a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the interface 207 could allow the gNB 102 to communicate over a wired or wireless local area network or over a wired or wireless connection to a larger network (such as the Internet). The interface 207 includes any suitable structure supporting communications over a wired or wireless connection, such as an Ethernet or RF transceiver.
[0305] The memory 206 is coupled to the controller / processor 205. Part of the memory 206 could include a random access memory (RAM), and another part of the memory 206 could include a Flash memory or other read only memory (ROM).
[0306] Although FIG. 2 illustrates one example of gNB 102, various changes may be made to FIG. 2. For example, the gNB 102 could include any number of each component shown in FIG. 2. As a particular example, an access point could include a number of interfaces 207, and the controller / processor 205 could support routing functions to route data between different network addresses. As another particular example, while shown as including a single instance of TX processing circuitry 203 and a single instance of RX processing circuitry 204, the gNB 102 could include multiple instances of each (such as one per RF transceiver). Also, various components in FIG. 2 could be combined, further subdivided, or omitted and additional components could be added according to particular needs.
[0307] FIG. 3 illustrates an example user equipment according to embodiments of the present disclosure. The embodiment of the UE 116 illustrated in FIG. 3 is for illustration only, and the UEs 111-115 and 117-119 of FIG. 1 could have the same or similar configuration. However, UEs come in a wide variety of configurations, and FIG. 3 does not limit the scope of the present disclosure to any particular implementation of a UE.
[0308] As shown in FIG. 3, the UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, TX processing circuitry 303, a microphone 304, and receive (RX) processing circuitry 305. The UE 116 also includes a speaker 306, a controller or processor 307, an input / output (I / O) interface (IF) 308, an input device 309, a touchscreen display 310, and a memory 311. The memory 311 includes an OS 312 and one or more applications 313.
[0309] The RF transceiver 302 receives, from the antenna 301, an incoming RF signal transmitted by a gNB of the network 100. The RF transceiver 302 down-converts the incoming RF signal to generate an IF or baseband signal. The IF or baseband signal is sent to the RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. The RX processing circuitry 305 transmits the processed baseband signal to the speaker 306 (such as for voice data) or to the processor 307 for further processing (such as for web browsing data).
[0310] The TX processing circuitry 303 receives analog or digital voice data from the microphone 304 or other outgoing baseband data (such as web data, e-mail, or interactive video game data) from the processor 307. The TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuitry 303 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 301.
[0311] The processor 307 can include one or more processors or other processing devices and execute the OS 312 stored in the memory 311 in order to control the overall operation of the UE 116. For example, the processor 307 could control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceiver 302, the RX processing circuitry 305, and the TX processing circuitry 303 in accordance with well-known principles. In some embodiments, the processor 307 includes at least one microprocessor or microcontroller.
[0312] The processor 307 is also capable of executing other processes and programs resident in the memory 311, such as processes for CSI reporting on uplink channel. The processor 307 can move data into or out of the memory 311 as required by an executing process. In some embodiments, the processor 307 is configured to execute the applications 313 based on the OS 312 or in response to signals received from gNBs or an operator. The processor 307 is also coupled to the I / O interface 308, which provides the UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. The I / O interface 308 is the communication path between these accessories and the processor 307.
[0313] The processor 307 is also coupled to the touchscreen display 310. The user of the UE 116 can use the touchscreen display 310 to enter data into the UE 116. The touchscreen display 310 may be a liquid crystal display, light emitting diode display, or other display capable of rendering text and / or at least limited graphics, such as from web sites.
[0314] The memory 311 is coupled to the processor 307. Part of the memory 311 could include RAM, and another part of the memory 311 could include a Flash memory or other ROM.
[0315] Although FIG. 3 illustrates one example of UE 116, various changes may be made to FIG. 3. For example, various components in FIG. 3 could be combined, further subdivided, or omitted and additional components could be added according to particular needs. As a particular example, the processor 307 could be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Also, while FIG. 3 illustrates the UE 116 configured as a mobile telephone or smartphone, UEs could be configured to operate as other types of mobile or stationary devices.
[0316] In order to make the purposes, technical solutions, and advantages of the present disclosure more clear, a further detailed description of the embodiments of the present disclosure will be provided below in conjunction with the accompanying drawings. The text and figures are provided as examples only to assist readers in understanding the present disclosure. They are not intended for and should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, based on the content disclosed herein, it is apparent to those skilled in the art that changes can be made to the illustrated embodiments and examples without departing from the scope of the present disclosure.
[0317] In the NR system, beam management is a method for finding an optimal transmission beam to improve the transmission quality of signals, thereby further improving the transmission capacity of the system. In the related art, a beam scanning technology will be used in the beam management. For example, the transmitter uses a beam to transmit a reference signal (RS) associated with it. Upon receiving the RS, the receiver calculates the received energy on the RS, i.e., Reference Signal Received Power (RSRP). The beam corresponding to the RS with the strongest energy is the optimal transmission beam. The transmitter uses the optimal transmission beam to transmit data, and the receiver can attain the strongest energy. Therefore, in order to find the optimal beam, the transmitter needs to traverse all candidate beams, i.e., the beam scanning technology.
[0318] However, in future 6G communication systems, continuing to use the current NR beam management method will face many problems. First, more RS resource overheads will be required in the 6G communication systems. This is because, in using the current beam management method based on traversal beam scanning, the RS resource overhead is directly proportional to the number of beams supported. For example, assuming a millimeter-wave product that can support 16 wide beams each supporting 10 narrow beams, it means that it will consume 176 RS resources (160 narrow beams + 16 wide beams). While in the future 6G communication systems, in order to support a greater coverage, beams will be designed to be narrower to obtain a higher beam gain. In this way, for a same angle coverage, more beams will need to be supported. For example, it is possible that a wide beam contains 40 narrow beams. In this way, for 16 wide beams, 656 RS resources (640 narrow beams + 16 wide beams) will be consumed, and these RS resources will be consumed periodically (periodically scanning the beams to update the optimal transmission beam). In addition, since each candidate beam is to be carried by at least one different Orthogonal Frequency Division Multiplexing (OFDM) symbol, the method of finding the optimal transmission beam by using traversal beam scanning will result in a huge delay. In summary, the huge RS resource overheads and large delay caused by the beam management method based on traversal beam scanning are problems that must be solved for future communication systems.
[0319] In order to solve at least one of the above technical problems or areas that need to be improved in the related art, a new beam management method can be used. For example, a Differential Beamforming (DBF)-based beam management method is an effective method to reduce RS overheads. This method may also be referred to as a differential beam method, a DBF method for beam management, or the like. This method performs the beam management based on two or three RSs, which can effectively reduce the number of beams that need to be scanned, reduce the energy consumption for beam scanning and beam measurement, reduce signaling overheads, and improve the communication efficiency.
[0320] In the embodiments of the present disclosure, considering complex application scenarios, such as a case where reference signal resources may be interfered, it is required to optimize the process of beam management. A new beam management method is proposed for this purpose.
[0321] In the embodiments of the present disclosure, the names or nomenclatures of various kinds of information described are not unique, as long as the role of the information, the content contained in the information, or the explanation or description of the information can be corresponded or associated. The information may be referred to as other names. For example, the beams in the embodiments of the present disclosure and the reference signal resources / reference signals associated with the beams correspond to each other, and the information corresponding to (or associated with, or related to, or regarding) the beams can also be replaced by the information corresponding to (or associated with, or related to, or regarding) the reference signal resources / reference signals. For example, the beam index can be an identifier of the beam, or may also be an identifier of the reference signal resource / reference signal corresponding to the beam.
[0322] Some term names involved in the embodiments of the present disclosure may adopt the term names already existing in the communication standards, such as the reference signal or reference signal resource. Some term names may be newly added or newly defined term names. These newly added or newly defined term names may also adopt other names in future communication standards, or may be described in other ways (such as a text description).
[0323] The beam management method provided in the embodiments of the present disclosure may at least include at least one of beam configuration, beam scanning, beam measurement, beam selection, measurement reporting, or beam switching.
[0324] The technical solutions of the embodiments of the present disclosure and the technical effects resulted therefrom will be described below by several exemplary implementations. It is to be noted that the following implementations may refer to, learn from or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.
[0325] In an embodiment of the present disclosure, a method performed by a UE in a communication system is provided. As shown in FIG. 4a, the method comprises:
[0326] step S101: receiving first configuration information, the first configuration information comprising information related to a first measurement quantity and a second measurement quantity, wherein a priority of the first measurement quantity is higher than a priority of the second measurement quantity;
[0327] step S102: receiving at least two reference signals related to the first measurement quantity; and
[0328] step S103: reporting, according to an interference indication and the priorities of the measurement quantities, measurement results of the measurement quantities based on the at least two reference signals.
[0329] The method according to the embodiment of the present disclosure can be performed by the UE. It can be understood that some of steps involving information interaction may be described from the UE side or from the network node side. For example, a terminal receives the configuration information, and accordingly, the network node side transmits the configuration information. For another example, a terminal reports a measurement report, and accordingly, the network node side receives the measurement report. However, it is not limited thereto.
[0330] In the embodiment of the present disclosure, the network node may include, but not limited to, a base station (BS) or a transmission reception point (TRP), or the like. For the convenience of description, in the following description, the network node may be described by taking the base station as an example.
[0331] Third configuration information may also be received, where the third configuration information includes information related to a reference signal resource set. Optionally, the third configuration information may also be described as including information for a reference signal resource or resource set. Optionally, the reference signal resources in the reference signal resource set are associated with at least two beams having an association relationship.
[0332] In the embodiment of the present disclosure, the method for beam management using at least two beams (or reference signals) having an association relationship means that the calculation of the measurement quantities for beam management requires the at least two beams (or reference signals) having the association relationship. Each beam has a reference signal corresponding to it.
[0333] Optionally, the reference signal resources in the reference signal resource set are associated with the at least two beams having the association relationship. It may also be described that the reference signal resource set includes reference signal resources having the association relationship. For example, the reference signal resources having the association relationship may include a first reference signal resource associated with a first beam and a second reference signal resource associated with a second beam, the second beam has an association relationship with the first beam, and there is at least one second beam.
[0334] It is to be noted that, in the embodiment of the present disclosure, the first beam may be replaced by the first reference signal or the first reference signal resource, and the second beam may be replaced by the second reference signal or the second reference signal resource. The description of the association relationship between the first beam and the second beam is applicable to the description of the association relationship between the first reference signal and the second reference signal, or to the description of the association relationship between the first reference signal resource and the second reference signal resource.
[0335] Optionally, the step S102 may also be described as receiving (based on the third configuration information) at least two reference signals having an association relationship, or determining at least two reference signal resources having an association relationship.
[0336] In the embodiment of the present disclosure, the association relationship means that, among multiple beams transmitted, there are at least two beams having overlapping parts, and / or the beam gains of the at least two beams have complementary peaks.
[0337] Optionally, as a specific implementation of the at least two beams (or reference signals) having the association relationship, the DBF method can be used. The DBF method is applied to two beams having the association relationship: the first beam and the second beam. The beam gains of the first and second beams have complementary peaks. When the beam gain of the first beam reaches a peak, the beam gain of the second beam is 0. The first beam is associated with the first reference signal, and the second beam is associated with the second reference signal.
[0338] Optionally, the second beam may include a third beam and a fourth beam, and correspondingly, the second reference signal may include a third reference signal and a fourth reference signal. The third beam has an association relationship with the first beam in a horizontal direction, that is, the beam gains in the horizontal direction have complementary peaks, which can be used for beam management in the horizontal direction. The fourth beam has an association relationship with the first beam in a vertical direction, that is, the beam gains in the vertical direction have complementary peaks, which can be used for beam management in the vertical direction.
[0339] Optionally, as a specific implementation of the at least two beams (or reference signals) having the association relationship, each of multiple beams transmitted has overlapping parts with at least one other beam. Optionally, the number of beams may be greater than or equal to 3. When the number of beams is greater than 3, the beams are divided into beam groups by taking three adjacent beams as a group. In a beam group consisting of three beams, the beam in the middle is referred to as the fifth beam, and the reference signal corresponding thereto is referred to as the fifth reference signal. The beams on both sides of the middle beam are referred to as the sixth beam and the seventh beam, and the reference signals corresponding thereto are referred to as the sixth reference signal and the seventh reference signal. Based on the sixth beam (the sixth reference signal) and / or the seventh beam (the seventh reference signal), it can be determined whether the transmission direction is biased towards the sixth beam or the seventh beam.
[0340] In the embodiment of the present disclosure, the type of reference signal is not limited, and the reference signal is a reference signal used for beam management. The reference signal may be a general downlink reference signal (GDRS) and / or a general uplink reference signal (GURS). The general downlink reference signal includes, but not limited to, a synchronization signal block (SSB), a physical broadcast channel (PBCH), a channel state information reference signal (CSI-RS), a positioning reference signal (PRS), or the like. The general uplink reference signal includes, but not limited to, a physical random access channel (PRACH), a sounding reference signal (SRS), or the like.
[0341] In the embodiment of the present disclosure, the UE reports measurement quantities of different priorities. The measurement quantities of different priorities at least include one of: the first measurement quantity (a measurement quantity corresponding to a first priority) and the second measurement quantity (a measurement quantity corresponding to a second priority), wherein the first priority is higher than the second priority, that is, the priority of the first measurement quantity is higher than the priority of the second measurement quantity.
[0342] Optionally, the measurement quantity of the first priority is determined based on multiple reference signals. The measurement quantity of the first priority may also be described as a measurement quantity related to the beam management method based on at least two beams (or reference signals) having an association relationship. That is, the beam management method based on at least two beams (or reference signals) having an association relationship may also be referred to as a beam management method related to the measurement quantity of the first priority.
[0343] Optionally, the beam management method based on at least two beams (or reference signals) having an association relationship may refer to obtaining angle information related to the transmission direction based on a ratio of at least two reference signals having an association relationship, and further adjusting the signal transmission direction by using a mapping relationship between the ratio and the angle information. The angle information at least includes one of: an angle deviation value, a beam pointing deviation value, an angle adjustment value, or a transmission angle value. The beam management method based on at least two beams (or reference signals) having an association relationship may also be referred to as a ratio-based beam management method.
[0344] In the embodiment of the present disclosure, a technical means of using at least two beams (or reference signals) having an association relationship to perform beam management is used to set forth the solutions. However, it is only exemplary and is for the convenience of the inventors to fully describe the technical concepts and technical principles, rather than to limit the principles of the present disclosure thereto. It can be understood that, while in the description of the present disclosure, the solutions are described by the signal transmission method based on at least two beams (or reference signals) having an association relationship, the principles disclosed in the present disclosure may be equally applied to scenarios using other technical solutions. For example, the technology of the present disclosure may also be applied to scenarios where the beam codebook design is optimized and / or other methods of using more than one beam (or reference signal) for beam management.
[0345] Optionally, the measurement quantity of the second priority is determined based on a reference signal, and the measurement quantity of the second priority may also be described as a measurement quantity related to the legacy beam management method.
[0346] Optionally, the first measurement quantity includes at least one of the following.
[0347] (1) Ratio of received signal values of at least two reference signals
[0348] The received signal values include at least one of:
[0349] 1. RSRP
[0350] The ratio of received signal values may be a ratio of RSRP. That is, upon receiving the reference signals corresponding to the two beams, the UE calculates the ratio of RSRP. As an example, the two reference signals may be at least two of the fifth reference signal, the sixth reference signal, and the seventh reference signal. The ratio of received signal values being the ratio of RSRP is applicable to the method in which the transmitter transmits multiple beams having overlapping parts for beam management.
[0351] 2. Reference Signal Received Path Power (RSRPP)
[0352] The ratio of received signal values may be a ratio of RSRPP.
[0353] When RSRPP is the received signal value, the path may be a first path in the time domain, a first path with a power value greater than (or not less than) a certain threshold in the time domain, or a path with the largest power value in the time domain. An index of the above path in a sampling path set is marked as a selected path index.
[0354] According to the selected path index corresponding to RSRPP of the first reference signal, RSRPP of the second reference signal on the selected path index is obtained to calculate the ratio. Specifically, the ratio of received signal values may be a ratio of RSRPP of the first reference signal on the selected path index to RSRPP of the second reference signal on the selected path index, and / or a ratio of RSRPP of the second reference signal on the selected path index to RSRPP of the first reference signal on the selected path index. The ratio of received signal values being the ratio of RSRPP is applicable to the beam management method using DBF.
[0355] 3. Equivalent channel estimates
[0356] The ratio of received signal values may be a ratio of equivalent channel estimates. The ratio of equivalent channel estimates may be a ratio of accumulated equivalent channel estimates, for example, a ratio of the accumulated value of frequency domain channel estimates of the second reference signal to the accumulated value of frequency domain channel estimates of the first reference signal. Alternatively, the ratio of equivalent channel estimates may be a ratio of equivalent channel estimates based on a peak, for example, a ratio of time domain channel estimates of the second reference signal and the first reference signal at a position where time domain channel estimates of the first reference signal reach a peak. The ratio of equivalent channel estimates may be a specific implementation of using the channel estimation to implement DBF-based beam management.
[0357] (2) Angle deviation value from reference direction
[0358] The angle deviation value may also be referred to as a beam pointing deviation value, or an angle adjustment value.
[0359] Optionally, the reference direction may be the normal direction (boresight direction) of the first beam, or may be a specific direction indicated by the base station. Based on the angle deviation value, the base station and / or the UE may know an angle deviation that needs to be adjusted for the correct transmission direction compared to the reference direction.
[0360] (3) Angle value corresponding to a transmission direction determined based on the ratio
[0361] It may be also referred to as a transmission angle value, which refers to an angle value corresponding to the transmission direction between the base station and the UE. The transmission angle value may be obtained by obtaining, according to the correspondence between the ratio of received signal values and the angle deviation value, the angle deviation value based on the ratio of received signal values, and then performing a calculation based on the angle deviation value and the angle value of the reference direction; or it may be obtained directly based on the ratio of received signal values according to the correspondence between the ratio of received signal values and the transmission angle value. Based on the transmission angle value, the base station and / or the UE may directly obtain the angle value corresponding to the correct transmission direction.
[0362] (4) Angle index related to the transmission direction
[0363] It may also be referred to as an expected angle index, which may be obtained based on the measurement results. Specifically, according to the transmission angle value (obtained directly, or obtained by performing a calculation based on the angle deviation value), and then according to the transmission directions or angle values of other beams, other angle indexes closest to the transmission angle value are determined. Optionally, the angle index corresponds to the beam index. Based on the expected angle index, the base station and / or the UE may directly obtain an angle corresponding to the optimal transmission beam, to achieve the optimal transmission between the base station and the UE.
[0364] (5) Beam index related to the transmission direction
[0365] It may also be referred to as an expected beam index, which may be obtained based on the measurement results. Specifically, according to the transmission angle value (obtained directly, or obtained by performing a calculation based on the angle deviation value), and then according to the transmission directions or angle values of other beams, other beam indexes closest to the transmission angle value are determined. Optionally, the beam index corresponds to the angle index. Based on the expected beam index, the base station and / or the UE may directly obtain the optimal transmission beam, to achieve the optimal transmission between the base station and the UE.
[0366] Optionally, the second measurement quantity includes at least one of:
[0367] (1) RSRP, i.e., the received power of the received reference signal;
[0368] (2) Reference Signal Received Quality (RSRQ);
[0369] (3) Signal-To-Noise and Interference Ratio (SINR); or
[0370] (4) Received Signal Strength Indicator (RSSI).
[0371] In the embodiment of the present invention, a technical means for performing beam management based on measurement quantities of different priorities is applied to signal transmission at the transmitter and / or signal reception at the receiver, so that the base station and the UE can quickly determine the transmission direction and / or reception direction of signals, which is conducive to quickly determining suitable transmit beams and / or receive beams.
[0372] In the embodiment of the present disclosure, an optional implementation is provided for the step S103. Specifically, it may comprise:
[0373] step S1031: reporting the measurement result of the first measurement quantity based on the at least two reference signals; and
[0374] step S1032: in case of receiving the interference indication, reporting the measurement result of the second measurement quantity based on at least one of the at least two reference signals.
[0375] Specifically, for different cases, the measurement quantities of different priorities may be used. In one example, when the measurement quantity of the first priority faces the interfered transmission, the measurement quantity of the second priority may be used for reporting, so as to make full use of signals that are not affected by the interfered transmission during the transmission of multiple beams. That is, the measurement quantity of the second priority may be used as a fallback mechanism to provide the measurement result of the legacy beam management method when the measurement quantity of the first priority cannot be obtained and / or the measurement quantity of the first priority is invalid, so as to improve the utilization of resources and the reliability of beam management. For another example, in some cases, the measurement quantity of the first priority may be used for reporting, so as to reduce the RS resource overhead and latency, and improve the efficiency of beam management.
[0376] In the embodiment of the present disclosure, multiple beams may be transmitted at the same time to reduce the latency caused by traversing beams in legacy beam management. The transmission of multiple beams at the same time may be the transmission of multiple beams at the same time by using multiple panels, or the transmission of multiple beams by using a same panel but in different frequency bands, for example by using a joint phase-time arrays (JPTA) technology. The calculation quantity in this method is the measurement quantity of the second priority, for example the second measurement quantity, such as RSRP. Compared with the method of configuring a new reference signal for interfered signal transmission to calculate the measurement quantity of the first priority, this method requires less delay, and further, the delay in reporting the measurement results caused by the calculation of the new measurement quantity is small.
[0377] In the embodiment of the present disclosure, the measurement quantity of the second priority (e.g., the second measurement quantity) may also provide purposes other than beam management. Optionally, the measurement quantity of the second priority may be used for channel quality estimation. For example, the RSPR reported by the UE may be used to measure the path loss to determine the transmit power.
[0378] In the embodiment of the present disclosure, the measurement quantities of different priorities may include, but not limited to, two priorities. For example, the second measurement quantity includes the second measurement quantity of a first priority and / or the second measurement quantity of a second priority. The second measurement quantity of the first priority is used for beam management, and the second measurement quantity of the second priority is used for channel quality estimation. For ease of understanding, the second measurement quantity of the first priority is described as a measurement quantity of the second A priority, and the second measurement quantity of the second priority is described as a measurement quantity of the second B priority. In other words, the measurement quantity of the second priority may be further divided into a measurement quantity of the second A priority and a measurement quantity of the second B priority.
[0379] Optionally, the measurement quantity of the second A priority includes RSRP, and the measurement quantity of the second B priority includes at least one of: RSRQ, SINR, or RSSI. The measurement quantity of the second A priority may be used to fall back to the legacy beam management method. The measurement quantity of the second B priority is a measurement quantity by which uninterfered reference signals can be used to provide channel quality estimation and other purposes.
[0380] Optionally, when the UE reports the measurement quantity of the second priority, it may further distinguish between reporting the measurement quantity of the second A priority and / or reporting the measurement quantity of the second B priority. For example, in the case of very poor channel states where the measurement quantity of the first priority and the measurement quantity of the second A priority used for beam management are both invalid, the measurement quantity of the second B priority, for example RSRQ, may be reported for interference measurement.
[0381] Specifically, for the step S1032, if it is determined that a channel measurement result meets a second condition, the measurement result of the second measurement quantity of the first priority may be reported; and if it is determined that a channel measurement result does not meet a second condition, the measurement result of the second measurement quantity of the second priority, for example RSRQ, may be reported for interference measurement. Those skilled in the art may set the case where the channel state does not meet the second condition, according to actual situations. For example, the second condition includes at least one of: the channel measurement result not meeting a predetermined value; a correlation of channel measurement results based on different reference signals being lower than a fourth threshold, etc., which will not be limited in the embodiment of the present disclosure.
[0382] In the embodiment of the present disclosure, the first configuration information may be understood as which measurement quantity of the first priority is reported, or which measurement quantity of the second priority is reported.
[0383] Optionally, the first configuration information may also include indication information indicating the measurement result of the measurement quantity of which priority is reported, for example, indicating by one or more bits that the measurement result of the measurement quantity of the first priority is reported, or indicating by one or more bits that the measurement result of the measurement quantity of the second priority is reported, or indicating by one or more bits that both the measurement result of the measurement quantity of the first priority and the measurement result of the measurement quantity of the second priority are reported. In the embodiment of the present disclosure, according to the indication of the base station, reporting the measurement quantity of the corresponding priority indicated improves the efficiency and reliability of beam management. For example, the indication information may indicate to report both the measurement quantity of the first priority and the measurement quantity of the second priority. The measurement quantity of the second priority may be used to assist in determining the accuracy of the measurement quantity of the first priority, so as to improve the reliability of beam management. Those skilled in the art may set different cases to be distinguished and the reported content corresponding to the different cases according to actual situations, which will not be limited in the embodiment of the present disclosure.
[0384] In the embodiment of the present disclosure, the first configuration information and the third configuration information are configuration information for beam management which is configured by the BS for the UE, wherein the first configuration information and the third configuration information may be transmitted to the UE at the same time or separately, and the first configuration information may also be implicitly configured by the third configuration information. That is, because the first configuration information is associated with the third configuration information, the first configuration information may be determined according to the third configuration information. The third configuration information may be a configuration related to reference signal resources, the first configuration information may be a configuration related to measurement result reporting, the third configuration information may be associated with the first configuration information, the UE may receive the reference signals based on the third configuration information, and the UE may determine which measurement quantity to measure and the measurement result of which measurement quantity to report, according to information configured in the first configuration information, and report the measurement result.
[0385] The specific names of the first configuration information and the third configuration information, and the specific configuration method for the BS to configure the first configuration information and the third configuration information for the UE, are not limited in the embodiment of the present disclosure. Optionally, the first configuration information and the third configuration information may be collectively referred to as configuration information for beam management. Optionally, the third configuration information may be referred to as a resource configuration, for example a channel state information (CSI) resource configuration, and the first configuration information may be referred to as a reporting configuration, for example a CSI reporting configuration.
[0386] Further, the signal transmission in the embodiment of the present disclosure includes at least one of: resource configuration, reporting configuration, signal transmission, measurement quantity calculation, measurement quantity reporting, etc., but not limited thereto. The resource configuration may be the resource configuration of reference signals, for example the resource configuration of CSI. The reporting configuration may be the reporting configuration of the measurement results, for example the reporting configuration of CSI. The signal transmission may be the transmission of reference signals, for example the transmission of reference signals based on the CSI resource configuration. The measurement quantity calculation and / or the measurement quantity reporting may be the reporting of the measurement results based on the reporting configuration, for example the reporting of CSI based on the CSI reporting configuration.
[0387] Optionally, the step S1031 may be described as: transmitting a first CSI report based on the at least two reference signals, wherein the first CSI report includes the measurement result of the first measurement quantity. Similarly, the step S1032 may be described as: in case of receiving an interference indication, transmitting a second CSI report based on at least one of the at least two reference signals, wherein the second CSI report includes the measurement result of the second measurement quantity.
[0388] In the embodiment of the present disclosure, the method for the UE to obtain which measurement quantity is to be reported may be at least one of: explicit, implicit, or preset.
[0389] In an optional implementation, the step S101 may be understood as an explicit method. That is, the UE explicitly receives the first configuration information (e.g. CSI reporting configuration) to determine the reporting configuration of the measurement quantity of the first priority and / or the reporting configuration of the measurement quantity of the second priority. The explicit method may allow the UE to clearly know the measurement quantity needed to be reported, and is applicable to a case where the base station has a clear reporting requirement for the measurement quantity, for example a case where the base station specifies a reporting requirement for a specific first measurement quantity in measurement quantity of the first priority and / or a specific second measurement quantity in measurement quantities of the second priority.
[0390] In another optional implementation, the UE explicitly receives the first configuration information (e.g. CSI reporting configuration), which includes the first measurement quantity of the base station (without clearly indicating the second measurement quantity), so that the UE can determine the reporting configuration of the measurement quantity of the first priority. The reporting configuration of the measurement quantity of the second priority is implicitly indicated or preset. For example, the reporting configuration of the measurement quantity of the second priority is implicitly indicated by the reporting configuration of the measurement quantity of the first priority (the first configuration information) (e.g., if the ratio of RSRP is configured for the first measurement quantity, it can be implicitly determined that the second measurement quantity is RSRP), and / or implicitly indicated by the third configuration information (e.g. CSI resource configuration) (e.g., which resource being configured for the third configuration information can implicitly indicate which corresponding measurement quantity is to be reported). In this implementation, the UE explicitly receives the reporting configuration of the measurement quantity of the first priority, which is applicable to a case where the base station has a clear reporting requirement for the measurement quantity of the first priority, for example a case where the base station specifies a reporting requirement for a specific first measurement quantity in measurement quantity of the first priority.
[0391] In yet another optional implementation, the UE implicitly determines the first measurement quantity and / or the second measurement quantity based on the third configuration information. That is, the UE implicitly determines the reporting configuration. When the UE receives the third configuration information (e.g. CSI resource configuration), that is, a configuration including at least two reference signals having an association relationship, it implicitly knows the reporting configuration of the measurement quantity of the first priority and / or the reporting configuration of the measurement quantity of the second priority. The implicit method can save signaling overhead.
[0392] In still another optional implementation, the first measurement quantity is implicitly indicated by the third configuration information, and the second information is preset. That is, the UE receives the third configuration information (e.g. CSI resource configuration, thus knowing that the CSI resource configuration includes the configuration of at least two reference signals having an association relationship), and implicitly knows the reporting configuration of the measurement quantity of the first priority. The reporting configuration of the measurement quantity of the second priority may be preset. This implementation can omit the CSI reporting configuration, thereby reducing signaling overhead.
[0393] That is, in the embodiment of the present disclosure, the step S101 may be replaced by any of the methods for obtaining which measurement quantity is to be reported.
[0394] In the embodiment of the present disclosure, the method for the UE to obtain a measurement quantity of which priority is to be reported may be at least one of: explicit, implicit, or preset.
[0395] In an optional implementation, the first configuration information may also include indication information indicating the measurement result of a measurement quantity of which priority is to be reported. That is, the UE explicitly receives the first configuration information (e.g. CSI reporting configuration) to determine a measurement quantity of which priority is to be reported. The explicit method may allow the UE to clearly know the priority of the measurement quantity to be reported, and is applicable to a case where the base station has a clear reporting requirement for the measurement quantity.
[0396] In another optional implementation, the first configuration information includes information related to the first measurement quantity and / or the second measurement quantity. The UE receives the first configuration information (e.g. CSI resource configuration, thus knowing that the CSI resource configuration includes the configuration of at least two reference signals having an association relationship), implicitly knows that the CSI reporting configuration is reporting the measurement quantity of the first priority and / or reporting the measurement quantity of the second priority, and thus reports the measurement quantity of the corresponding priority. For example, if only the reporting configuration of the measurement quantity of the first priority is configured in the first configuration information, the measurement result of the measurement quantity of the first priority is reported. Other cases are similar and will not be repeated here. Alternatively, the UE receives the second configuration information. The second configuration information includes information related to the measurement result reporting resource. Upon receiving the second configuration information, the UE implicitly knows the reporting resource of the measurement quantity of which priority is configured, and thus reports the measurement quantity of the corresponding priority.
[0397] In yet another optional implementation, the measurement quantity of which priority is to be reported may be preset. For example, the UE presets the reporting of the measurement quantity of the first priority as a default configuration (as shown in the step S1031), and when the UE receives the interference indication, and / or the UE determines that the measurement result of the measurement quantity of the first priority is invalid, it reports the measurement quantity of the second priority. Alternatively, other methods are used to report both the measurement result of the first priority and the measurement quantity of the second priority.
[0398] That is, in the embodiment of the present disclosure, based on the obtained any method of reporting the measurement quantity of which priority, the step S1031 and the step S1032 may be replaced by a method of reporting the measurement quantity of the corresponding priority.
[0399] In the embodiment of the present disclosure, the measurement result of the second measurement quantity may also be reported based on at least one of the at least two reference signals in case that the measurement result of the first measurement quantity is invalid (e.g., this can be done with or without receiving the interference indication).
[0400] In the embodiment of the present disclosure, a calculation related to CSI may be performed, and based on the CSI, it is determined whether the measurement result of the first measurement quantity is valid.
[0401] Optionally, the measurement result of the first measurement quantity being invalid comprises at least one of the following cases.
[0402] (1) If a correlation of channel states corresponding to different reference signals is lower than a first threshold, it is determined that the measurement result of the first measurement quantity is invalid.
[0403] The channel states may be obtained based on channel estimation results, the calculation related to CSI, or the like. As an example, if a correlation of the channel estimation results of different reference signals in the frequency domain and / or time domain is low, it can be determined that the channel changes too fast, which may cause the measurement result of the measurement quantity of the first priority to be invalid. Optionally, the correlation of the channel estimation results of different reference signals may be determined by calculating a similarity between the channel estimation results of different reference signals. A specific method of calculating the similarity may be set according to the actual situations, which will not be limited in the embodiment of the present disclosure.
[0404] (2) If the measurement result of the first measurement quantity exceeds a first range, it is determined that the measurement result of the first measurement quantity is invalid.
[0405] The first range may refer to a measurement range and / or a reporting range. For example, when the CSI (e.g. SINR) is outside a certain threshold range (e.g. the first range), the measurement quantity of the first priority is invalid.
[0406] (3) If the received signal value corresponding to the first measurement quantity is not within a second range, it is determined that the measurement result of the first measurement quantity is invalid.
[0407] If the received signal value participating in the calculation of the first measurement quantity is not within an expected second range, or if the received signal value participating in the calculation of the first measurement quantity does not meet the expected condition, it is determined that the measurement result of the first measurement quantity is invalid.
[0408] In the embodiment of the present disclosure, another optional implementation is provided for reporting the measurement quantities of different priorities. Specifically, as shown in FIG. 4b, it may comprise the following steps.
[0409] Step S401: The UE receives a CSI resource configuration, the CSI resource configuration comprising a configuration of at least two reference signals.
[0410] Optionally, the at least two reference signals have an association relationship.
[0411] Specifically, the association relationship of the reference signals may mean that beam gains of beams corresponding to the at least two reference signals have complementary peaks. That is, the reference signals may be a first reference signal associated with a first beam related to DBF-based beam management, and / or a second reference signal associated with a second beam.
[0412] The association relationship of the reference signals may also mean that, among multiple beams, each beam has an overlapping part with other beams. That is, the reference signals may also be a fifth reference signal associated with a fifth beam related to beam management based on multiple overlapping beams, and / or a sixth reference signal associated with a sixth beam, and / or a seventh reference signal associated with a seventh beam.
[0413] When the reference signal is the first reference signal, and / or the fifth reference signal and / or the sixth reference signal and / or the seventh reference signal, the corresponding beam transmitted by the base station is generated in a legacy manner. Thus, the corresponding second measurement quantity is a measurement quantity based on a legacy beam, which is compatible with the application scenario of the legacy measurement quantity.
[0414] In the embodiment of the present disclosure, upon receiving the CSI resource configuration, the UE can not only know information about the reference signal resources, but also implicitly know the beam management method adopted by the base station, for example, a beam management method based on at least two reference signals having an association relationship, and further knows information about the measurement quantity, for example the measurement quantity of the first priority corresponding to this beam management method.
[0415] Step S402: The UE receives a CSI reporting configuration. The CSI reporting configuration includes at least one of: the reporting configuration of the measurement quantity of the first priority (e.g. configurating the first measurement quantity), and the reporting configuration of the measurement quantity of the second priority (e.g. configurating the second measurement quantity).
[0416] Step S403: The UE receives transmission of the reference signals.
[0417] Step S404: The UE performs a calculation of the measurement quantities. The calculation of the measurement quantities includes at least one of: a calculation of the measurement quantity of the first priority (e.g. the first measurement quantity), or a calculation of the measurement quantity of the second priority (e.g. the second measurement quantity).
[0418] Step S405: The UE receives a downlink interference indication. The downlink interference indication includes a downlink preemption indication, or the like.
[0419] Step S406: The UE performs a calculation related to CSI, and determines, based on the CSI, whether the measurement quantity of the first priority is valid.
[0420] For example, the method for the UE to perform a calculation related to CSI may be a channel estimation, and the method for determining, based on the CSI, whether the measurement quantity of the first priority is valid may be that when the CSI (e.g. SINR) is outside a certain threshold range, the measurement quantity of the first priority is invalid.
[0421] Step S407: The UE performs a CSI reporting. The CSI reporting includes at least one of: the measurement quantity of the first priority and the measurement quantity of the second priority.
[0422] Step S408: The UE receives data transmission after the base station adjusts the direction.
[0423] In the embodiment of the present disclosure, an optional implementation is provided for the configuration of reporting resources for the measurement quantity of the first priority and / or the measurement quantity of the second priority. Optionally, the receiving UE may receive second configuration information.
[0424] In an optional implementation, the second configuration information includes a first reporting resource corresponding to the first measurement quantity and a second reporting resource corresponding to the second measurement quantity. That is, the measurement quantity of the first priority and the measurement quantity of the second priority are respectively configured with reporting resources. The configuration of reporting resources for the measurement quantity of the first priority and the measurement quantity of the second priority can support the reporting of measurement quantities of two priorities. In some scenarios, the reporting of the measurement quantity of the second priority can assist the base station in determining the accuracy of the measurement quantity of the first priority, and the measurement quantity of the second priority has other purposes other than beam management.
[0425] In another optional implementation, the second configuration information includes a third reporting resource corresponding to the first measurement quantity and the second measurement quantity. The step S1031 may include: reporting the measurement result of the first measurement quantity based on the second configuration information, and transmitting second indication information, the second indication information being used to indicate that the reported measurement result corresponds to the first measurement quantity. The step S1032 may include: reporting the measurement result of the second measurement quantity based on the second configuration information, and transmitting third indication information, the third indication information being used to indicate that the reported measurement result corresponds to the second measurement quantity. That is, the measurement quantity of the first priority and the measurement quantity of the second priority share the reporting resources and are distinguished by the indication information. The reporting resources shown include, but not limited to, fields. The measurement quantity of the first priority and the measurement quantity of the second priority share the reporting resources and are distinguished by the indication information, which can save signaling overhead.
[0426] In the embodiment of the present disclosure, the interference indication includes information related to interfered reference signal resources and / or uninterfered reference signal resources. In combination with the interference indication, the measurement results corrupted by interference can be determined. The measurement results corrupted by interference may be processed (it may also be described as the processing of eliminating the measurement quantities corrupted by interference, which refers to a processing method when the calculated measurement quantities contain the measurement quantities corrupted by interference), wherein the measurement quantities corrupted by interference refers to measurement quantities calculated based on the reference signals in the interfered transmission.
[0427] (1) The UE does not report the measurement results corrupted by interference.
[0428] (2) The UE reports the measurement results corrupted by interference and / or reports a corrupted measurement result flag.
[0429] (3) The measurement results corrupted by interference are removed, and filtering is performed on the measurement results not corrupted by interference for subsequent reporting. That is, among multiple measurement results, if several of them are corrupted by interference, the UE removes the measurement results corrupted by interference and processes the measurement results not corrupted by interference, for example reporting after filtering.
[0430] (4) When a proportion of the measurement results corrupted by interference reaches a second threshold, the measurement results are not reported. That is, among multiple measurement results, when several of them are corrupted by interference and the proportion of the measurement results corrupted by interference reaches or exceeds a certain threshold (e.g. the second threshold), the UE does not report the measurement results.
[0431] (5) When the proportion of the measurement results corrupted by interference reaches a third threshold, first indication information is reported, the first indication information being used to indicate that the proportion of the measurement results corrupted by interference reaches the third threshold, and / or being used to request a reallocation of the reference signal resources. That is, among multiple measurement results, when several of them are corrupted by interference and the proportion of the measurement results corrupted by interference reaches or exceeds a certain threshold (e.g. the third threshold), the UE reports an indication (the first indication information). The indication may inform the base station that the proportion of the measurement results corrupted by interference reaches or exceeds a certain threshold, and / or request the reallocation of reference resources for measurement. Optionally, the third threshold may be 50%.
[0432] (6) Among multiple measurement results, the UE removes the measurement result with the highest value, removes the measurement result with the lowest value, and performs filtering, for example moving averaging, on the remaining measurement results for subsequent reporting.
[0433] (7) Filtering is performed on multiple measurement results for subsequent reporting. For example, among the multiple measurement quantities, the UE processes the measurement results by using filtering, for example moving averaging. The method is simple and easy to implement.
[0434] In the embodiment of the present disclosure, the UE may report a UE capability (also referred to as storage capability). The UE capability includes the ability to store the received reference signals and / or the measurement results based on the reference signals until the current measurement reporting is completed. For example, before using the UE to report measurement quantities of different priorities, the UE may report its storage capability, or before using the method of reusing the reference signal resources, the UE may report its storage capability. Based on the storage capability, the base station may determine the method of reusing the reference signal resources which is suitable for the UE.
[0435] The ability to store the received reference signals may be the ability to store the reference signals after being received until the current measurement reporting is completed. Based on this ability, the base station may schedule the method of reusing the reference signal resources which is suitable for the UE, for example a reconfiguration way of resources that are not preempted.
[0436] The ability to store the measurement results may be the ability to store the measurement results based on the reference signals until the current measurement reporting is completed. Based on this ability, the base station may schedule the method of reusing the reference signal resources which is suitable for the UE, for example a configuration of new reference signal resources.
[0437] Optionally, the ability to store the measurement results comprises at least one of:
[0438] (1) the ability to store the measurement result of the first measurement quantity;
[0439] (2) the ability to store the measurement result of the second measurement quantity; or
[0440] (3) the ability to store the received signal value corresponding to a calculation of the first measurement quantity, for example RSRP and / or RSRPP and / or equivalent channel estimates.
[0441] In the embodiment of the present disclosure, for different abilities to store the measurement results, the base station can know the reporting status of the UE, and / or the base station can perform different scheduling.
[0442] In the embodiment of the present disclosure, another method performed by a UE in a communication system is provided. As shown in FIG. 5, the method comprises:
[0443] step S201: receiving third configuration information, the third configuration information comprising information related to a reference signal resource set;
[0444] step S202: receiving at least two reference signals based on the third configuration information;
[0445] step S203: in case of receiving an interference indication, determining uninterfered third reference signal resources in the reference signal resource set based on the interference indication, wherein the interference indication comprises information related to interfered fourth reference signal resources and / or the third reference signal resources;
[0446] step S204: determining fifth reference signal resources corresponding to the at least two reference signals based on the third reference signal resources; and
[0447] step S205: measuring and reporting measurement results of the at least two reference signals based on the fifth reference signal resources.
[0448] In the embodiment of the present disclosure, the reference signal resources in the reference signal resource set configured by the third configuration information may have an association relationship. The detailed description of the association relationship may refer to the above, and will not be repeated here.
[0449] Optionally, the step S202 may also be described as receiving at least two reference signals having an association relationship, or determining at least two reference signal resources having an association relationship.
[0450] In the embodiment of the present disclosure, the type of reference signals is not limited, and it can be similarly referred to in the above description, which will not be repeated here.
[0451] In the embodiment of the present disclosure, when interference occurs in the transmission of the reference signals in the time domain and / or frequency domain, the uninterfered reference signal resources can be reused to improve the utilization of resources.
[0452] For example, the uninterfered third reference signal resources in the reference signal resource set are determined based on the interference indication, the fifth reference signal resources corresponding to the at least two reference signals are determined based on the third reference signal resources, and the measurement results of the at least two reference signals are measured and reported based on the fifth reference signal resources.
[0453] In the embodiment of the present disclosure, various embodiments of the method performed by the UE in the communication system can be combined with various embodiments of the previous method performed by the UE in the communication system. For example, the step S205 can use the method of steps S101 to S103, but it is not limited thereto. Those skilled in the art can combine various embodiments of the two methods, and these combinations are applicable to the present disclosure, and should also be included in the protection scope of the present disclosure.
[0454] In the embodiment of the present disclosure, an optional implementation is provided for the step S204, which may specifically comprise:
[0455] step S2041: receiving fourth configuration information, the fourth configuration information being used to indicate that the reference signal resources are to be re-determined; and
[0456] step S2042: determining, according to the fourth configuration information, the fifth reference signal resources corresponding to the at least two reference signals based on the third reference signal resources.
[0457] The fourth configuration information may also be understood as a reference signal resource reconfiguration indication.
[0458] Optionally, the reuse of reference signal resources includes at least one of: reconfiguration of the reference signal resources, recalculation of the measurement quantities, or reporting of the recalculated measurement quantities.
[0459] In the embodiment of the present disclosure, the reconfiguration of the reference signal resources refers to a manner in which the UE receives an interference indication and / or a reconfiguration indication of the reference signal resources (fourth configuration information), and obtains time domain resources and / or frequency domain resources of new reference signal resources according to the indication. Upon receiving the interference indication and / or the reference signal resource reconfiguration indication, the UE knows that the time domain resources and / or frequency domain resources of the received reference signals were reconfigured, and calculates and / or reports the measurement quantities again based on the reconfigured reference signal resources.
[0460] In an optional implementation, the reconfiguration of the reference signal resources at least includes the reconfiguration of uninterfered (e.g. non-preempted) resources. This method does not add new reference signals. The received reference signal resources are reused to complete the measurement and reporting related to beam management.
[0461] Specifically, the reconfiguration of the time domain resources and / or frequency domain resources of the received reference signals may be explicit or implicit.
[0462] Optionally, in case of receiving the interference indication and / or the fourth configuration information, the step S204 may specifically comprise: reallocating the third reference signal resources to obtain the fifth reference signal resources, and reallocating the uninterfered reference signal resources, for example, re-dividing the uninterfered reference signal resources according to a proportion. Specifically, the proportion may be a configurated proportion of the original reference signal resources. That is, based on a proportion of reference signal resources corresponding to the at least two reference signals or a configurated proportion, the third reference signal resources are reallocated to obtain the fifth reference signal resources, and the UE can report the measurement results (which may be the measurement result of the first measurement quantity and / or the second measurement quantity) based on the re-divided fifth reference signal resources and the at least two reference signals (received, or stored due to the storage capability).
[0463] For example, for the beam management method using DBF, when the transmission of the second reference signal is interfered and the transmission of the first reference signal is not interfered, the base station re-divides the time domain and / or frequency domain resources of the first reference signal, for use as new first reference signal resources and second reference signal resources for transmission of the first reference signal and the second reference signal. When the configurated proportion of the time domain resources and / or frequency domain resources of the original first reference signal resources and second reference signal resources is 1:1, the time domain resources and / or frequency domain resources of the first reference signal are evenly divided into two parts, for use as new first reference signal resources and second reference signal resources for transmission of the first reference signal and the second reference signal. Optionally, when the second reference signal contains a third reference signal and a fourth reference signal, the resources of the original first reference signal will be divided into three parts. In this way, the uninterfered reference signal resources are fully utilized and divided according to the configurated proportion of the reference signals in the original transmission mode. When the UE uses the new reference signal resources for calculation, it can directly use a mapping relationship between the ratio of received signal values based on the original reference signals and the angle information, which is easy to implement.
[0464] For another example, the base station may indicate the time domain resource proportion and / or frequency domain resource proportion of the re-divided reference signal resources.
[0465] Optionally, the reallocating the third reference signal resources to obtain the fifth reference signal resources at least comprises: in case that the reference signal resource set comprises multiple reference signal resources and the third reference signal resources comprise partial reference signal resources among the multiple reference signal resources, determining the partial reference signal resources as the fifth reference signal resources. For example, if there are some uninterfered resources in reference signal resources corresponding to the reference signals of which transmission is interfered, the signals are transmitted using those uninterfered resources. That is, the UE may report the measurement results based on the reference signals transmitted by some uninterfered ones of reference signal resources corresponding to the interfered reference signals, and the reference signals transmitted by the reference signal resources corresponding to the uninterfered reference signals.
[0466] For example, for the beam management method using DBF, when the transmission of the second reference signal is partially interfered and the transmission of the first reference signal is not interfered, the first reference signal is transmitted in the original manner, and the second reference signal is transmitted by the uninterfered time domain resources and / or frequency domain resources of the second reference signal. In this way, the uninterfered reference signal resources are used for transmission in the original manner and are not affected by the interfered transmission of other reference signals.
[0467] Optionally, the reallocating the third reference signal resources to obtain the fifth reference signal resources at least comprises: based on the resource configuration information indicated by the interference indication and / or the fourth configuration information, determining the fifth reference signal resources in the third reference signal resources. For example, the interference indication and / or the fourth configuration information indicates the location and / or length of frequency domain and / or time domain resource elements in the third reference signal resources, to determine the fifth reference signal resources.
[0468] For example, for the beam management method using DBF, when the transmission of the second reference signal is interfered and the transmission of the first reference signal is not interfered, the base station may indicate the location of a resource used to transmit the first reference signal in the first reference signal resources, and / or the location of a resource used to transmit the second reference signal. In this way, the uninterfered reference signal resources can be fully utilized and the reference signals can be effectively transmitted.
[0469] In another optional implementation, the reconfiguration of the reference signal resources at least includes the configuration of new reference signal resources. Optionally, the configured new reference signal resources may be used for the transmission of the interfered reference signals, that is, new time domain resources and / or frequency domain resources are configured for the interfered reference signal resources for compensatory transmission, which may also be described as compensatory transmission resources for the interfered reference signal.
[0470] Optionally, beam management related to the measurement quantity of the first priority is performed on both the reference signal based on the compensatory transmission and the uninterfered reference signal, so as to make full use of the uninterfered signal transmission. Or optionally, the configured new reference signal resources support the legacy beam management method. When the beam management method related to the measurement quantity of the first priority is interfered, new resources may be reconfigured, and the uninterfered reference signal resources may be used to calculate the measurement quantity of the second priority, that is, falling back to the legacy beam management method. For the latter method, multiple beams may be transmitted at the same time to reduce the latency caused by traversing the beams in legacy beam management. The calculation quantity is the measurement quantity of the second priority, for example RSRP. Compared with the method of configuring a new reference signal for the interfered signal transmission to calculate the measurement quantity of the first priority, this method requires less delay, and further, the delay in reporting the measurement result caused by the calculation of the new measurement quantity is small.
[0471] Optionally, in case that the interference indication and / or the fourth configuration information is received, the step S204 at least comprises: after the interfered transmission, by using a non-periodic CSI resource configuration, explicitly reconfiguring the time domain resources and / or frequency domain resources for the transmission of the interfered reference signals.
[0472] Optionally, in case that the interference indication and / or the fourth configuration information is received, the step S204 at least comprises: determining the sixth reference signal resources indicated by the interference indication and / or the fourth configuration information, and the third reference signal resource as the fifth reference signal resources. Optionally, the UE implicitly notifies the time domain information and / or frequency domain information of the new reference signal resources by the interference indication and / or the reference signal resource reconfiguration indication. That is, the UE may report the measurement results, based on the reference signals received on the reference signal resources indicated by the interference indication and / or the fourth configuration information, and / or the uninterfered reference signals.
[0473] Optionally, the indication (including the interference indication and / or the reference signal resource reconfiguration indication) may implicitly notify the UE of a distance between the reconfigured reference signal resources and the original reference signal resources in the time domain resource and / or frequency domain resource. The distance may also be described as an interval, a shift, an offset, or the like. Specifically, the interference indication and / or the fourth configuration information includes a first offset. The first offset is a time domain offset and / or frequency domain offset between the sixth reference signal resources and the reference signal resources in at least two reference signal resource groups. The sixth reference signal resources are determined based on the third configuration information and the first offset.
[0474] Alternatively, the indication (including the interference indication and / or the reference signal resource reconfiguration indication) may implicitly notify the UE of a distance between the reconfigured reference signal resources and the indication in the time domain resource and / or frequency domain resource. Similarly, the distance may also be described as an interval, a shift, an offset, or the like. Specifically, the interference indication and / or the fourth configuration information include a second offset. The second offset is a time domain offset and / or frequency domain offset between the sixth reference signal resources and a first downlink resource. The first downlink resource is a downlink resource for receiving the interference indication and / or the fourth configuration information. The sixth reference signal resources are determined based on at least one of the interference indication and the fourth configuration information, and based on the second offset.
[0475] It should be noted that the offset mentioned in at least one embodiment of the present disclosure may refer to an offset between the starting position of one resource and the starting position of another resource, or may refer to an offset between the starting position of one resource and the ending position of another resource, or may refer to an offset between the ending position of one resource and the ending position of another resource, etc., which will not be limited in the embodiment of the present disclosure.
[0476] In yet another optional implementation, the reconfiguration of the reference signal resources at least includes a reassociation of the reference signal resources.
[0477] The reassociation of the reference signals refers to the establishment of a new association relationship between the uninterfered reference signal resources when encountering interfered transmission (e.g. downlink preemption). The association relationship may be the establishment of a new association relationship between the closest available reference signals that satisfy an association relationship. This method is applicable to a case where the reference signal is transmitted multiple times, for example periodic reference signal transmission and / or semi-periodic reference signal transmission and / or multiple non-periodic reference signal transmissions.
[0478] Optionally, after the current reference signal transmission is completed, new reference signal resources are allocated to establish an association relationship with the reference signals that have not established the association relationship in this transmission, for measurement and calculation, so as to make full use of all transmission resources. Alternatively, the reference signals that failed to establish the association relationship are no longer transmitted, that is, the reference signals that failed to establish the association relationship in this transmission are no longer transmitted to save transmission resources.
[0479] Specifically, in case of receiving the interference indication, the step S204 may comprise: in case that the reference signal resource set comprises at least two reference signal resource groups, determining at least one third reference signal resource in a first reference signal resource group in which the fourth reference signal resources are located, and at least one third reference signal resource in the other of the at least two reference signal resource groups except the first reference signal resource group, as the fifth reference signal resources. It may also be understood as establishing an association relationship between these third reference signal resources. Optionally, reference signals on the reference signal resources that cannot be used as the fifth reference signal resources are no longer transmitted.
[0480] For example, in using the DBF-based beam management method, the transmission of the reference signals transmitted multiple times follows: transmission of the first reference signal (denoted by reference signal 1A), transmission of the second reference signal (denoted by reference signal 2A), transmission of the first reference signal (denoted by reference signal 1B), transmission of the second reference signal (denoted by reference signal 2B), transmission of the first reference signal (denoted by reference signal 1C), and transmission of the second reference signal (denoted by reference signal 2C). The reference signal 1A and the reference signal 2A satisfy an association relationship, the reference signal 1B and the reference signal 2B satisfy an association relationship, and the reference signal 1C and the reference signal 2C satisfy an association relationship. When the reference signal 1A is interfered, the reference signal 1B and the reference signal 2A may form a new association relationship to participate in measurement and calculation, the reference signal 2B and the reference signal 1C may also form a new association relationship to participate in measurement and calculation, and so on. After completing the transmission of the reference signal 2C, new first reference signal resources may be allocated to form an association relationship with the reference signal 2C for measurement and calculation. After the reference signal 1C is transmitted, the reference signal 2C may be regarded as a reference signal that cannot establish the association relationship, and the reference signal 2C is no longer transmitted.
[0481] This method is also applicable to a beam management method where each of the multiple beams transmitted has an overlapping part with at least one other beam. When the transmission of certain reference signal is interfered, the remaining reference signals establish a new association relationship with the closest available reference signals that satisfy the association relationship, and the measurement quantities are calculated and reported based on the new association relationship.
[0482] A specific implementation of reassociation of the reference signal resources may also be a group association. The group association refers to dividing the reference signals into several groups having an association relationship. Specifically, any reference signal in each group has an association relationship with any reference signal in other groups. One reference signal is selected from each group. The measurement quantities may be calculated based on these several reference signals.
[0483] For example, when using the DBF-based beam management method, the first reference signals and the second reference signals transmitted periodically are divided into two groups, wherein the first group includes the first reference signals transmitted periodically and the second group includes the second reference signals transmitted periodically. A first group of reference signals have an association relationship with a second group of reference signals. Specifically, the beam gain of beams corresponding to the first reference signals in the first group and the beam gain of beams corresponding to any second reference signal in the second group have complementary peaks. Upon receiving the reference signals, when the UE receives the interference indication indicating that the transmission of certain reference signal is interfered, the uninterfered reference signals in the two groups are newly associated nearby, thereby completing the calculation and reporting of the measurement quantities.
[0484] In the embodiment of the present disclosure, the determining at least one third reference signal resource in a first reference signal resource group in which the fourth reference signal resources are located, and at least one third reference signal resource in the other of the at least two reference signal resource groups except the first reference signal resource group, as the fifth reference signal resources, is triggered based on at least one of the interference indication and fifth configuration information. The fifth configuration information includes configuration information related to reassociation of the reference signal resources. It may also be described as follows: the calculation of the measurement quantities by the UE based on the new association relationship may be triggered by an interference instruction and / or the configuration related to reassociation of the reference signal resources (the fifth configuration information). For example, when the UE receives the group association configuration, once the interference instruction is received, the UE knows the new association relationship, and further, the UE performs measurement based on the new association relationship. This method does not require a new instruction configuration, and the establishment of the new association relationship is implicitly indicated by the interference instruction. For another example, it may be explicitly indicated by a new configuration related to reassociation (the fifth configuration information), to instruct the UE to perform related operations.
[0485] In the embodiment of the present disclosure, the reference signal resource reconfiguration indication (fourth configuration information) may be a separate indication, or may be multiplexed with the interference indication, for example a downlink preemption indication. Specifically, the interference indication and / or the fourth configuration information includes at least one of the following.
[0486] (1) Information indicating that the reference signal resources are reconfigured;
[0487] Based on the indication information, the UE knows that the reference signals need to be re-measured.
[0488] (2) Information indicating a reconfiguration way of the reference signal resources;
[0489] For example, whether to use the reconfiguration of uninterfered (e.g. non-preempted) resources, or to use the configuration of new reference signal resources is indicated. Further, when indicating to use the reconfiguration of uninterfered (e.g. non-preempted) resources, whether to re-divide the uninterfered reference signal resources in proportion, or to receive, if there are some uninterfered resources in reference signal resources corresponding to the reference signals of which transmission is interfered, the reference signals by those uninterfered resources, is indicated; and when indicating to use the configuration of new reference signal resources, whether to configure the new reference signal resources for the transmission of interfered reference signals, or to configure the new reference signal resources to support the legacy beam management method, is indicated.
[0490] Based on the indication information, the UE knows the measurement way to be used for re-measurement.
[0491] (3) Information indicating the reference signal resources to be used for re-measurement.
[0492] For example, the time domain resource information and / or frequency domain resource information of the reference signal resources to be used for re-measurement is indicated. Based on the time-frequency information, the UE may use the corresponding reference signal resources to participate in the calculation of the measurement quantities. Specifically, when the configuration method is re-dividing the uninterfered reference signal resources in proportion, the time domain resource proportion and / or frequency domain resource proportion of the re-divided reference signal resources may be indicated. Based on the time domain resource proportion and / or the frequency domain resource proportion, the measurement results of the measurement quantities may be weighted, and angle information may be obtained according to a mapping relationship between the weighted measurement results of the measurement quantities and the angle information.
[0493] In the embodiment of the present disclosure, the recalculation of measurement quantities refers to recalculating the measurement quantities using the reconfigured reference signal resources. The method of recalculating the measurement quantities corresponds to the method of reconfiguring the reference signal resources. Specifically, the recalculated measurement quantities include at least one of: the measurement quantity of a first priority and the measurement quantity of a second priority.
[0494] In the embodiment of the present disclosure, the reporting the recalculated measurement quantities refers to reporting the measurement quantities by the time domain resources and / or frequency domain resources after completing the recalculation of measurement quantities. The base station uses a reporting result of the recalculated measurement quantities to perform beam management. Specifically, the reporting of the recalculated measurement quantities may include at least one of the following ways.
[0495] (1) Receiving configuration information related to a fourth reporting resource, the fourth reporting resource being used to transmit the measurement result based on the third configuration information and the measurement result based on the fifth reference signal resources, and reporting, based on the fourth reporting resource, the measurement results of the at least two reference signals.
[0496] This method may also be understood as reporting by the time domain resources and / or frequency domain resources used for reporting the original measurement quantities.
[0497] This method is applicable to a case where the recalculation of measurement quantities requires a short period of time and has no impact on the overall timing process.
[0498] For example, this method is applicable to a case where the configuration of new reference signal resources supports the legacy beam management method. Since the measurement quantity required by the legacy beam management method, for example the measurement quantity of the second priority, requires a short period of time, the time domain resources and / or frequency domain resources used for reporting the original measurement quantities may be used for reporting.
[0499] This method may also be applicable to a case where there is enough time between the completion of the recalculation of measurement quantities and the reporting. Optionally, when transmitting an interference instruction and / or a reference signal resource reconfiguration indication, the base station determines whether there is sufficient time for the UE to report the recalculated measurement quantities according to the time when a new reference signal is transmitted, and / or the time required to complete the calculation of new measurement quantity, and / or the completion time of the measurement report.
[0500] (2) Receiving configuration information related to a fifth reporting resource and a sixth reporting resource, the fifth reporting resource being used to transmit the measurement result based on the third configuration information, the sixth reporting resource being used to transmit the measurement result based on the fifth reference signal resources, and reporting, based on the sixth reporting resource, the measurement results of the at least two reference signals.
[0501] This method may also be understood as reconfiguring the reporting resources, for example, for the recalculated measurement quantities, reconfiguring new time domain resources and / or frequency domain resources for reporting the measurement quantities, or may be described as reconfiguring the time domain resources and / or frequency domain resources for reporting.
[0502] Specifically, the reconfiguring the reporting resources may be transmitting a non-periodic CSI reporting configuration, that is, the sixth configuration information may be a non-periodic CSI reporting configuration; or the reconfiguring the reporting resources may also be related to the interference instruction of the base station, and / or the reference signal resource reconfiguration indication (the fourth configuration information), and / or the configuration of new reference signal resources (e.g. ninth configuration information). For example, the sixth configuration information is at least one of the interference instruction, the fourth configuration information, or the ninth configuration information.
[0503] Specifically, the new reporting resource configuration may be triggered by the interference instruction, and / or the reference signal resource reconfiguration indication (the fourth configuration information), and / or the configuration of new reference signal resources (e.g. the ninth configuration information), or the UE may be implicitly notified of the new reporting resource configuration. For example, the configuration of new reference signal resources is associated with the new reporting resource configuration. For another example, the interference instruction and / or the reference signal resource reconfiguration indication may implicitly notify the UE of the time domain resources and / or frequency domain resources for reporting.
[0504] Optionally, the reporting may be performed after receiving the interference instruction and / or the reference signal resource reconfiguration indication, and / or completing the transmission of the new reference signal resources for several time domain units (e.g. several slots and / or several symbols).
[0505] The method of reconfiguring the reporting resources is flexible to use and has little impact on other channels or signal transmissions.
[0506] This method is applicable to a case where the time domain resources and / or frequency domain resources used for reporting the original measurement quantities cannot meet the demand and it is necessary to reconfigure new time domain resources and / or frequency domain resources to report the measurement quantities.
[0507] Specifically, one case may be that the time to transmit the interference instruction of the base station, and / or the reference signal resource reconfiguration indication, and / or the new reference signals is too close to the time to report the original measurement quantities, such that there is not enough time to recalculate the measurement quantities.
[0508] (3) Receiving configuration information related to a third offset, the third offset being a time domain offset and / or frequency domain offset between the fifth reporting resource and the sixth reporting resource, and reporting, based on the fifth reporting resource and the third offset, the measurement results of the at least two reference signals.
[0509] This method may also be understood as reconfiguring new time domain resources and / or frequency domain resources to report the measurement quantities, specifically by shifting the reporting resources.
[0510] The shifting of the reporting resources refers to the shifting of the time domain resources and / or frequency domain resources used for reporting the recalculated measurement quantities relative to the time domain resources and / or frequency domain resources used for reporting the original measurement quantities. Specifically, the shifting may refer to that the resources occupied by the reporting of the recalculated measurement quantities and the resources occupied by the reporting of the original measurement quantities meet a certain interval requirement, which may be for example the third offset, in the time domain and / or frequency domain.
[0511] In the embodiment of the present disclosure, the time domain resources include, but not limited to, frames, slots, short slots, symbols, etc.; and the frequency domain resources include, but not limited to, bandwidth part (BWP), half BWP, resource block (RB), resource element (RE), or the like.
[0512] For example, the shifting of the reporting resources may be reporting the measurement results of the recalculated measurement quantities after several slots and / or several symbols from the time domain resources used for reporting the original measurement quantities.
[0513] The method of shifting the reporting resources is simple and easy to implement, and no new signaling overhead is required.
[0514] In the embodiment of the present disclosure, in correspondence with the recalculation of the measurement quantities, the reporting of the recalculated measurement quantities includes at least one of: the measurement quantity of the first priority and the measurement quantity of the second priority.
[0515] In the embodiment of the present disclosure, the base station performs beam management based on the reported measurement quantities.
[0516] In the embodiment of the present disclosure, for a reference signal transmitted multiple times, the calculation and reporting method of the measurement quantities include one of the following: after the measurement quantities are calculated based on several reference signals satisfying an association relationship, each calculated measurement quantity may be reported separately; or when the reference signal is transmitted multiple times, the multiple calculated measurement quantities may be filtered to eliminate the influence of fast fading.
[0517] Specifically, the measurement results corrupted by interference may be processed based on at least one of the following ways (it may also be described as the processing of eliminating the measurement quantities corrupted by interference, which refers to a processing method when the calculated measurement quantities contain the measurement quantities corrupted by interference), wherein the measurement quantities corrupted by interference refer to the measurement quantities calculated based on the reference signal in the interfered transmission.
[0518] (1) The UE does not report the measurement results corrupted by interference.
[0519] (2) The UE reports the measurement results corrupted by interference, and / or reports a corrupted measurement result flag.
[0520] (3) The measurement results corrupted by interference are removed, and filtering is performed on the measurement results not corrupted by interference for subsequent reporting. That is, among multiple measurement results, if several of them are corrupted by interference, the UE removes the measurement results corrupted by interference and processes the measurement results not corrupted by interference, for example reporting after filtering.
[0521] (4) When a proportion of the measurement results corrupted by interference reaches a second threshold, the measurement results are not reported. That is, among multiple measurement results, when several of them are corrupted by interference and the proportion of the measurement results corrupted by interference reaches or exceeds a certain threshold (e.g. the second threshold), the UE does not report the measurement results.
[0522] (5) When the proportion of the measurement results corrupted by interference reaches a third threshold, first indication information is reported, the first indication information being used to indicate that the proportion of the measurement results corrupted by interference reaches the third threshold, and / or being used to request a reallocation of the reference signal resources. That is, among multiple measurement results, when several of them are corrupted by interference and the proportion of the measurement results corrupted by interference reaches or exceeds a certain threshold (e.g. the third threshold), the UE reports an indication (the first indication information). The indication may inform the base station that the proportion of the measurement results corrupted by interference reaches or exceeds a certain threshold, and / or request the reallocation of reference resources for measurement. Optionally, the third threshold may be 50%.
[0523] (6) The UE receives a flush-out instruction (which may also referred to as flush-out indication), the flush-out instruction being used to indicate whether the previously received reference signals and / or the measurement results based on the previously received reference signals are corrupted by interference, and / or the flush-out instruction being used to indicate whether the currently received reference signals are to be combined with the previously received reference signals, and / or the flush-out instruction being used to indicate whether the measurement results based on the currently received reference signals are to be combined with the measurement results based on the previously received reference signals. For example, when the flush-out instruction is 0, it indicates that the previously received reference signals and / or the measurement results based on the previously received reference signals are corrupted by interference, and when the flush-out instruction is 1, it indicates that the currently received reference signals are to be combined with the previously received reference signals, and / or the measurement results based on the currently received reference signals is to be combined with the measurement results based on the previously received reference signals.
[0524] (7) The UE receives a flush-out instruction, the flush-out instruction being used to indicate a flush-out process, the flush-out process being used to flush-out an eighth reference signal indicated by the flush-out instruction and the eighth reference signal before it, and / or the measurement result based on the eighth reference signal, or the flush-out process being used to flush-out a ninth reference signal indicated by the flush-out instruction and the ninth reference signal after it, and / or the measurement result based on the ninth reference signal, or the flush-out process being used to flush-out a tenth reference signal before the reference signal indicated by the flush-out instruction, and / or the measurement result based on the tenth reference signal, or the flush-out process being used to flush-out an eleventh reference signal after the reference signal indicated by the flush-out instruction, and / or the measurement result based on the eleventh reference signal. That is, in the embodiment of the present disclosure, the reference signal to be flushed out may include the reference signal indicated by the flush-out instruction, or may not include the reference signal indicated by the flush-out instruction. In a case where the reference signal to be flushed out includes the reference signal indicated by the flush-out instruction, the reference signal indicated by the flush-out instruction and the reference signal before it are referred to as the eighth reference signal, or the reference signal indicated by the flush-out instruction and the reference signal after it are referred to as the ninth reference signal. In a case where the reference signal to be flushed out does not include the reference signal indicated by the flush-out instruction, the reference signal before the reference signal indicated by the flush-out instruction is referred to as the tenth reference signal, and the reference signal after the reference signal indicated by the flush-out instruction is referred to as the eleventh reference signal. The naming of these serial numbers only indicates the distinction between reference signals in different cases, and cannot be understood as any limitation on their content, quantity, type or order. In other words, the flush-out instruction may instruct the UE to perform a flush-out process before or after a certain node. Specifically, the node may flush-out the reference signals before or after the transmission of the nth reference signal in this transmission cycle and / or the measurement results based on the reference signals.
[0525] Optionally, the UE may first report its UE capability which includes the ability to store the received reference signals and / or the measurement results based on the reference signals until the current measurement reporting is completed, that is, how many reference signals and / or the measurement results based on the reference signals the UE can store in one transmission cycle. The base station may configure the flush-out instruction based on its capability. Optionally, the transmission cycle may be the time between two pieces of downlink control information (DCI).
[0526] 8) Among multiple measurement results, the UE removes the measurement result with the highest value, removes the measurement result with the lowest value, and performs filtering, for example moving averaging, on the remaining measurement results for subsequent reporting.
[0527] (9) Filtering is performed on multiple measurement results for subsequent reporting. For example, among multiple measurement quantities, the UE processes the measurement results by using filtering, for example moving averaging. The method is simple and easy to implement.
[0528] In the embodiment of the present disclosure, the UE may report a UE capability (also referred to as storage capability). The UE capability includes the ability to store the received reference signals and / or the measurement results based on the reference signals until the current measurement reporting is completed. For example, before using the UE to report measurement quantities of different priorities, the UE may report its storage capability, or before using the method of reusing the reference signal resources, the UE may report its storage capability. Based on the storage capability, the base station may determine the method of reusing the reference signal resources which is suitable for the UE.
[0529] The ability to store the received reference signals may be the ability to store the reference signals until the current measurement reporting is completed after the reference signals are received. Based on this ability, the base station may schedule the method of reusing the reference signal resources which is suitable for the UE, for example the reconfiguration of resources that are not preempted.
[0530] The ability to store the measurement results may be the ability to store the measurement results based on the reference signals until the current measurement reporting is completed. Based on this ability, the base station may schedule the method of reusing the reference signal resources which is suitable for the UE, for example the configuration of new reference signal resources.
[0531] In the embodiment of the present disclosure, for different abilities to store the measurement results, the base station can know the reporting status of the UE, and / or the base station can perform different scheduling.
[0532] In the embodiment of the present disclosure, the flush-out instruction mentioned above may be configured based on the UE capability. The flush-out instruction is used to indicate a flush-out process. The flush-out process is used to flush-out an eighth reference signal indicated by the flush-out instruction and the eighth reference signal before it, and / or the measurement result based on the eighth reference signal, or the flush-out process is used to flush-out a ninth reference signal indicated by the flush-out instruction and the ninth reference signal after it, and / or the measurement result based on the ninth reference signal, or the flush-out process is used to flush-out a tenth reference signal before the reference signal indicated by the flush-out instruction, and / or the measurement result based on the tenth reference signal, or the flush-out process is used to flush-out an eleventh reference signal after the reference signal indicated by the flush-out instruction, and / or the measurement result based on the eleventh reference signal. For a specific implementation of the flush-out instruction, please refer to the introduction above, which will not be repeated here.
[0533] An embodiment of the present disclosure also provides a codebook generation method for simultaneously emitting beams in multiple directions to realize DBF-based beam management.
[0534] Optionally, the technology used in the embodiment of the present disclosure to simultaneously emit beams in multiple directions is the joint phase-time arrays technology, i.e., JPTA technology. Assuming that the transmitter has antenna units, corresponding to phase shifters, and true time delays (TTDs). The data on each subcarrier of the transmitter is related to the phase shifters and TTDs. Specifically, when the transmitter uses a uniform linear antenna array and the subcarrier set is , the transmitted signal on each subcarrier is:
[0535]
[0536] where is the subcarrier number, ;
[0537] is the phase of the phase shifter connected to the th antenna,
[0538] is the carrier frequency domain (including the center frequency domain) on the th subcarrier;
[0539] is the delay value of the th TTD,
[0540] is the scalar data on the th subcarrier;
[0541] is the digital beamforming value on the th subcarrier.
[0542] The total power transmitted by the base station is
[0543]
[0544] The -dimensional diagonal matrix T describes the influence of the phase shifter, and T may be referred to as a phase shift matrix; the
[0545] - dimensional vector describes the influence of the TTD, and the vector may be referred to as a delay vector.
[0546] It is to be noted that there is no restriction on the form of the antenna array here, and other antenna array forms may also be used, for example a planar array. Optionally, when the corresponding antenna array is a planar array, the corresponding phase shift matrix T is no longer a diagonal matrix, and the corresponding is a delay matrix. When , the corresponding phase shift matrix is dimensional, and the corresponding delay matrix is also dimensional.
[0547] The methods of implementing DBF-based beam management using a JPTA structure include at least one of the following.
[0548] The methods of implementing DBF-based beam management using a JPTA structure include at least one of the following.
[0549] 1. A frequency domain implementation of DBF-based beam management. The frequency domain implementation of DBF-based beam management refers to simultaneously emit at least two beams having an association relationship in the frequency domain, as shown in FIG. 6a, where the association relationship means that the beam gains of the two beams have complementary peaks. A specific implementation of the codebook includes at least one of the following.
[0550] (1) The frequency domain bandwidth of the reference signal is divided into at least two parts, wherein at least one part is used to implement the first beam (corresponding to the first reference signal), and at least another part is used to implement the second beam (corresponding to the second reference signal). Optionally, the second beam may be further divided into a third beam (corresponding to a third reference signal) and a fourth beam (corresponding to a fourth reference signal), wherein the third beam and the fourth beam have been described above and will not be described repeatedly here. When the second beam includes the third beam and the fourth beam, the corresponding frequency bandwidth will be divided into three parts. Here, by taking the division of the frequency bandwidth into two parts as an example, the frequency band range corresponding to the first beam is set to and the frequency band range corresponding to the second beam is set to where
[0551] (2) A target beam is set. Let the target beam be is the target beam on the frequency band corresponding to the first beam, satisfying:
[0552] The target beam on each subcarrier satisfies is the array response vector, denoted as Optionally, the array response vector is related to the target angle. When using a discrete Fourier transform (DFT) codebook, the array response vector is:
[0553]
[0554] where is the center frequency domain; is the target angle.
[0555] is the target beam on the frequency band corresponding to the second beam, satisfying:
[0556]
[0557] The target beam on each subcarrier satisfies is the array response vector, denoted as
[0558] Optionally, when using the DFT codebook, the array response vector is:
[0559]
[0560] (3) The phase shift matrix T and the delay vector (or matrix) are jointly determined so that the generated beam satisfies the target beam.
[0561] Based on this, as shown in FIG. 6b, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0562] step S601: the UE receives a CSI resource configuration, the CSI resource configuration comprising the definition of the association relationship related to JPTA+DBF in the frequency domain;
[0563] step S602: the UE receives a CSI reporting configuration, the CSI reporting configuration comprising a configuration of the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0564] step S603: the UE receives transmission of the reference signals;
[0565] step S604: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority based on DBF;
[0566] step S605: the UE reports the measurement result of the measurement quantity of the first priority and / or the measurement result of the measurement quantity of the second priority; or
[0567] step S606: the UE receives data transmission after the base station adjusts the direction.
[0568] In the embodiment of the present disclosure, the method of implementing DBF-based beam management in the frequency domain can simultaneously generate at least one group of beams satisfying the association relationship to implement the DBF-based beam management. Further, using this method can implement the DBF-based beam management in different directions at the same time. At this time, the frequency domain bandwidth of the reference signal may be divided in a manner that all beams of a same type are placed in one frequency band. The manner of placing beams of a same type in one frequency band can make the generated beams have a good beam pattern. For example, the frequency domain bandwidth is divided into two parts, one of which is used to implement the first beam and the other is used to implement the second beam.
[0569] 2. A time domain implementation of DBF-based beam management. The time domain implementation of DBF-based beam management refers to transmitting at least one first beam (or first reference signal) at a first occasion and transmitting at least one second beam (or second reference signal) at a second occasion, as shown in FIG. 7a. One occasion corresponds to the time for transmitting a beam (or reference signal). Optionally, the occasion may be one or more slots and / or one or more symbols. The specific implementation of the codebook includes at least one of:
[0570] (1) At least one first beam is generated at the first occasion, and a phase shift matrix and / or a delay vector (or matrix) is obtained accordingly. Optionally, when the number of first beams generated is 1, only the phase shift matrix is required, or the delay vector (or matrix) element is a constant. Assuming that the phase shift matrix is and the corresponding delay vector (or matrix) is .
[0571] Specifically, the specific implementation of the phase shift matrix and the delay vector (or matrix) includes at least one of the following.
[0572] 1) A target beam is set. Let the target beam of the first beam be where the target beam on each subcarrier satisfies is the array response vector, denoted as
[0573] Optionally, the array response vector is related to the target angle.
[0574] 2) The phase shift matrix and the delay vector (or matrix) are jointly determined so that the generated beam satisfies the target beam.
[0575] (2) At least one second beam is generated at the second occasion, wherein the generation method of the second beam includes at least one of the following.
[0576] 1) The phase shift matrix of the second beam satisfies
[0577]
[0578] and the corresponding delay vector (or matrix) is .
[0579] This method is simple to implement. Based on the phase shift matrix and / or delay vector (or matrix) of the first beam generated at the first occasion, the second beam at the second occasion can be generated. Implementing simultaneous beam management in multiple directions by using a same delay vector (or matrix) saves delay.
[0580] 2) The specific implementation of the phase shift matrix and delay vector (or matrix) of the second beam includes at least one of the following.
[0581] A target beam is set. Let the target beam of the second beam be where the target beam on each subcarrier satisfies
[0582] is the array response vector, denoted as Optionally, the array response vector is related to the target angle.
[0583] The phase shift matrix and the delay vector (or matrix) are jointly determined so that the generated beam satisfies the target beam.
[0584] Based on this, as shown in FIG. 7b, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0585] step S701: the UE receives a CSI resource configuration, the CSI resource configuration comprising the definition of the association relationship related to JPTA+DBF in the time domain;
[0586] step S702: the UE receives a CSI reporting configuration, the CSI reporting configuration comprising a configuration of the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0587] step S703: the UE receives transmission of the reference signals.
[0588] step S704: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority based on DBF;
[0589] step S705: the UE reports the measurement result of the measurement quantity of the first priority and / or the measurement result of the measurement quantity of the second priority; or
[0590] step S706: the UE receives data transmission after the base station adjusts the direction.
[0591] This method optimizes the design and generates the phase shift matrix and delay vector (or matrix) of the first beam, and the phase shift matrix and delay vector (or matrix) of the second beam, respectively, and the generated beams have a better beam pattern, thereby having a better angle estimation performance.
[0592] Based on at least one of the above embodiments, as shown in FIG. 8, the complete implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0593] step S801: the UE receives a CSI resource configuration, the CSI resource configuration comprising the reconfiguration of the interfered RS;
[0594] step S802: the UE receives a CSI reporting configuration, the CSI reporting configuration comprising a configuration of the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0595] step S803: after the base station generates a codebook, the UE receives the transmission of the reference signals;
[0596] step S804: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority based on DBF;
[0597] step S805: the UE reports the measurement result of the measurement quantity of the first priority and / or the measurement result of the measurement quantity of the second priority; and
[0598] step S806: the UE receives data transmission after the base station adjusts the direction.
[0599] Based on at least one of the above embodiments, different combinations may be applicable to different cases, and several examples are specifically described below.
[0600] Example 1
[0601] As shown in FIG. 9, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0602] step S1.1: the UE receives a CSI resource configuration, the CSI resource configuration comprising a configuration of at least two reference signals having an association relationship;
[0603] step S1.2: the UE receives a CSI reporting configuration, the CSI reporting configuration comprising a configuration of the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0604] step S1.3: the UE receives the transmission of the reference signals;
[0605] step S1.4: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0606] step S1.5: the UE receives an interference indication from the base station, for example a downlink preemption indication; or
[0607] step S1.6: the UE reports the measurement result of the measurement quantity of the second priority;
[0608] the UE receives data transmission after the base station adjusts the direction.
[0609] This example is applicable to a case where the UE receives a clear interference indication, knows that the measurement result of the first priority is invalid, and therefore reports the measurement quantity of the second priority to make full use of uninterfered reference signals. At this time, the measurement quantity of the second priority reported by the UE is based on the reference signals transmitted in an uninterfered manner. The interference indication obtained by the UE triggers the UE to report the measurement quantity of the second priority.
[0610] In this example, there is no clear order requirement between the UE receiving the interference instruction from the base station and the UE calculating the measurement quantity of the first priority and / or the measurement quantity of the second priority. Specifically, upon receiving the transmission of the reference signals, the base station can calculate the measurement quantity of the first priority and / or the measurement quantity of the second priority. When reporting, the content to be reported is selected according to the received interference indication. In addition, the UE may receive the interference indication first and then calculate the measurement quantities. Optionally, when the UE receives the interference indication first and then calculates the measurement quantities, the UE may not calculate the measurement quantity of the first priority because, at this time, the UE already knows that the measurement quantity of the first priority is invalid.
[0611] In this example, when interference occurs in the transmission of the reference signal in the time domain and / or frequency domain, the uninterfered reference signal resources can be reused.
[0612] Example 2
[0613] As shown in FIG. 10, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0614] step S2.1: the UE receives a CSI resource configuration, the CSI resource configuration comprising a configuration of at least two reference signals having an association relationship;
[0615] step S2.2: the UE receives a CSI reporting configuration, the CSI reporting configuration comprising a configuration of the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0616] step S2.3: the UE receives the transmission of the reference signals.
[0617] step S2.4: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0618] step S2.5: the UE reports the measurement result of the measurement quantity of the first priority; or
[0619] step S2.6: the UE receives data transmission after the base station adjusts the direction.
[0620] This example is applicable to a case where the UE does not receive the interference indication. In this case, for the configuration of the measurement quantities of the two priorities received, the measurement result of the measurement quantity of the first priority is valid, and the UE may report only the measurement quantity of the first priority for beam management. Optionally, this method is applicable to a case where the reporting resources of the UE are limited. In this case, only the measurement quantity of the first priority is reported, which can save the signaling overhead for reporting.
[0621] Optionally, the manner in which the UE receives the CSI reporting configuration may be explicit, implicit or preset. For details, please refer to the above description, which will not be repeated here.
[0622] Example 3
[0623] As shown in FIG. 11, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0624] step S3.1: the UE receives a CSI resource configuration, the CSI resource configuration comprising a configuration of at least two reference signals having an association relationship;
[0625] step S3.2: the UE receives a CSI reporting configuration, the CSI reporting configuration comprising a configuration of the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0626] step S3.3: the UE receives the transmission of the reference signals;
[0627] step S3.4: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0628] step S3.5: the UE performs channel estimation, the purpose of which is to determine whether the measurement quantity of the first priority is valid (normal);
[0629] step S3.6: if not, the UE reports the measurement quantity of the second priority; or
[0630] step S3.7: the UE receives data transmission after the base station adjusts the direction.
[0631] This example is applicable to a case where the UE does not receive the interference indication, but the UE determines that the measurement quantity of the first priority is invalid, so the UE reports the measurement quantity of the second priority. The measurement quantity of the second priority reported by the UE may be used to fall back to the legacy beam management method, or used for purposes other than beam management. For example, RSRP is used for path loss estimation.
[0632] Specifically, this example may be applicable to a case where the base station is unknown of the channel state and performs beam management based on at least two beams (or reference signals) having an association relationship, but the UE determines, based on the received signals, that the beam management method cannot be used currently, that is, the measurement quantity of the first priority is invalid. Further, the case where it is determined, based on the received signals, that the beam management method cannot be used currently may be as follows: the UE performs channel estimation based on the received signals and finds that the channel changes too fast. The case where it is determined that the channel changes too fast may be as follows: the correlation between channel estimates based on different reference signals in the frequency domain and / or time domain is low. Optionally, the case where the base station is unknown of the channel state may be the case of initial access.
[0633] Specifically, this example may also be applicable to a case where the UE finds that the measurement quantity of the first priority is invalid. The measurement quantity of the first priority being invalid includes one of the following: the measurement quantity of the first priority exceeds the measurement range and / or the reporting range, the received signal value participating in the calculation of the measurement quantity of the first priority is not within the expected range and / or does not meet the expected conditions, or the like.
[0634] In the reporting method, the UE reports only the measurement quantity of the second priority, which can save the signaling overhead for reporting and is applicable to a case where the reporting resources are limited. Furthermore, the UE first determines that the measurement quantity of the first priority is invalid, and falls back to the reporting of the measurement quantity of the second priority. This saves the time for the base station to receive the measurement quantity of the first priority and then reconfigure the measurement quantity of the second priority after determining that the measurement quantity of the first priority is invalid, and then the UE to perform re-measurement based on the new configuration and report.
[0635] Optionally, the manner in which the UE receives the CSI reporting configuration may be explicit, implicit or preset. For details, please refer to the above description, which will not be repeated here.
[0636] Optionally, a specific implementation of this example is as shown in FIG. 12. In FIG. 12, the behavior on the UE side includes:
[0637] step S1: the UE receives a CSI resource configuration, the CSI resource configuration comprising the resource configuration of at least two reference signals having an association relationship;
[0638] step S2 (optional): the UE receives a configuration of the measurement quantity of the first priority and / or the
[0639] measurement quantity of the second priority;
[0640] step S3: the UE receives transmission of the reference signals;
[0641] step S4: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0642] step S5 (optional): the UE performs channel estimation and determines that the measurement quantity of the first priority is invalid;
[0643] step S6: the UE reports CSI, the content of which is the measurement quantity of the second priority; and
[0644] step S7: the UE receives data reception after the direction is adjusted.
[0645] In FIG. 12, that the UE receives the configuration of the measurement quantity of the first priority and the measurement quantity of the second priority and does not receive the interference indication is taken as an example.
[0646] Optionally, the order of steps S4 and S5 may be interchanged.
[0647] Optionally, when the UE determines that the measurement quantity of the first priority is invalid based on the result of the channel estimation and / or the measurement quantity of the second priority, the measurement quantity of the first priority may not be calculated.
[0648] Example 4
[0649] As shown in FIG. 13, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0650] step S4.1: the UE receives a CSI resource configuration, the CSI resource configuration comprising a configuration of at least two reference signals having an association relationship;
[0651] step S4.2: the UE receives a CSI reporting configuration, the CSI reporting configuration comprising a configuration of the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0652] step S4.3: the UE receives the transmission of the reference signals;
[0653] step S4.4: the UE calculates the measurement quantity of the first priority and / or the measurement quantity of the second priority;
[0654] step S4.5: the UE reports the measurement quantity of the first priority and the measurement quantity of the second priority; or
[0655] step S4.6: the UE receives data transmission after the base station adjusts the direction.
[0656] This example is applicable to a case where the UE is unable to determine whether the measurement quantity is valid, and is also applicable to a case where the base station needs to report measurement quantities of two priorities, for example, the base station uses the measurement quantity of the first priority for beam management and uses the measurement quantity of the second priority for other purposes.
[0657] Optionally, the manner in which the UE receives the CSI reporting configuration may be explicit, implicit or preset, to obtain the reporting configuration of the measurement quantity of the first priority and the measurement quantity of the second priority. For details, please refer to the introduction above, which will not be repeated here.
[0658] Example 5
[0659] As shown in FIG. 14, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0660] step S5.1: the UE receives a CSI resource configuration, the CSI resource configuration comprising a configuration of at least two reference signals having an association relationship;
[0661] step S5.2: the UE receives a CSI reporting configuration, including: the UE receives, from the base station, the configuration of the measurement quantity of the first priority or the measurement quantity of the second priority;
[0662] step S5.3: the UE receives the transmission of the reference signals;
[0663] step S5.4: the UE calculates the measurement quantity of the first priority or the measurement quantity of the second priority;
[0664] step S5.5: the UE reports the measurement quantity of the first priority or the measurement quantity of the second priority; or
[0665] step S5.6: the UE receives data transmission after the base station adjusts the direction.
[0666] This example is applicable to a case where the base station specifies the measurement quantity of a priority for reporting.
[0667] Optionally, the manner in which the UE receives the CSI reporting configuration may be explicit, implicit or preset, to obtain the reporting configuration of the measurement quantity of the first priority or the measurement quantity of the second priority. For details, please refer to the introduction above, which will not be repeated here.
[0668] Example 6
[0669] As shown in FIG. 15, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0670] step S6.1: the UE reports a storage capability;
[0671] step S6.2: the UE receives a CSI resource configuration and / or a CSI reporting configuration;
[0672] step S6.3: the UE receives the transmission of the reference signals;
[0673] step S6.4: the UE calculates the measurement quantities;
[0674] step S6.5: the UE receives an interference indication and / or a reference signal resource reallocation indication (fourth configuration information);
[0675] step S6.6 (optional): the UE receives a new CSI resource configuration and / or a CSI reporting configuration;
[0676] step S6.7: the UE recalculates the measurement quantities;
[0677] step S6.8: the UE reports the measurement quantities; or
[0678] step S6.9: the UE receives data transmission after the base station adjusts the direction.
[0679] In this example, the reuse of reference signal resources is involved. For example, when interference occurs in the transmission of the reference signal in the time domain and / or frequency domain, the uninterfered reference signal resources can be reused. The reuse of reference signal resources includes at least one of: reconfiguration of reference signal resources, recalculation of measurement quantities, or reporting of recalculated measurement quantities. For example, as shown in FIG. 16, the uninterfered reference signal resources are re-divided into two or three parts. For another example, as shown in FIG. 17, the reference signal transmitted by the uninterfered part of reference signal resources corresponding to the interfered reference signal, and the reference signal transmitted by the reference signal resources corresponding to the uninterfered reference signal, continue to be used. The specific implementation has been described in detail above and will not be repeated here.
[0680] For the UE, as shown in FIG. 18, once the UE initially receives the RS, the expected RS is as shown by the dotted box in FIG. 18. After receiving the reference signal resource reallocation indication, the UE knows that the RS just received cannot be measured as expected, and it is necessary to measure it according to the reallocated resources, as shown by the bolded box in FIG. 18.
[0681] In this example, the step S6.6 may also adopt the reconfiguration of resources that are not preempted.
[0682] In this example, for the method of reporting the recalculated measurement quantities, please refer to the introduction above, which will not be repeated here.
[0683] In this example, the storage capability has been described in detail above and will not be repeated here.
[0684] In this example, the reference signal resources can be fully utilized, and the UE performs measurement, calculation and then reporting based on a new reference signal configuration.
[0685] Example 7
[0686] As shown in FIG. 19, the specific implementation of the UE reporting measurement quantities of different priorities may be at least one of:
[0687] step S7.1: the UE reports a storage capability;
[0688] step S7.2: the UE receives a CSI resource configuration in which at least two associated reference signal groups are defined;
[0689] step S7.3: the UE receives a CSI reporting configuration;
[0690] step S7.4: the UE receives the transmission of the reference signals;
[0691] step S7.5: the UE receives an interference indication and / or a configuration related to reassociation of the reference signal resources;
[0692] step S7.6: the UE calculates the measurement quantities, and the calculation of the measurement quantities being based on several reference signals that are closest to each other in the associated reference signal groups;
[0693] step S7.7 (optional): the UE receives a CSI resource configuration, the CSI resource configuration being used to allocate new reference signal resources to establish an association relationship with reference signals that have not established an association relationship in this transmission;
[0694] step S7.8: the UE receives the transmission of new reference signals;
[0695] step S7.9: the UE reports the measurement quantities; or
[0696] step S7.10: the UE receives data transmission after the base station adjusts the direction.
[0697] In this example, the storage capability has been described in detail above and will not be repeated here.
[0698] This example involves the reuse of reference signal resources, for example reassociation of the reference signal resources. For example, as shown in FIG. 20, group A includes an RS corresponding to the first beam; group B includes an RS corresponding to the second beam; the RS in group A may establish an association relationship with any RS in group B. Optionally, an association relationship may usually be established with the closest available RS. The specific implementation has been described in detail above and will not be repeated here.
[0699] In this example, after the measurement quantity calculation is completed, the time domain resources and / or frequency domain resources used for reporting the measurement quantities may be reconfigured. Specifically, the method of reconfiguring the time domain resources and / or frequency domain resources may be at least one of: shifting the reporting resources or reconfiguring the reporting resources. The specific implementation has been described in detail above and will not be repeated here. Optionally, the method of shifting the reporting resources may be transmitting the measurement quantities after several slots and / or several symbols from the time domain resources used for reporting the original measurement quantities. It is simple and easy to implement.
[0700] In this example, for the calculation and reporting method of the measurement quantities of the reference signals transmitted multiple times, please refer to the introduction above. For example, based on FIG. 19, optionally, as shown in FIGS. 21 and 22, the UE performs measurement and stores the measurement results according to the periodic RS transmission, removes the measurement results corrupted by interference, and performs filtering (e.g. averaging) on the measurement results not corrupted by interference for subsequent reporting. Or optionally, as shown in FIGS. 23 and 24, the flush-out instruction indicates whether the previous measurement results are corrupted by interference. For example, when the flush-out instruction is 0, a flush-out process is performed, and when the flush-out instruction is 1, the current measurement results are combined with the previous measurement results. Or optionally, as shown in FIG. 25, among multiple measurement results, the UE removes the measurement result with the highest value, removes the measurement result with the lowest value, and performs filtering (e.g. averaging) on the remaining measurement results. The specific implementation has been described in detail above and will not be repeated here.
[0701] In this example, the calculation of the measurement quantities by the UE based on a new association relationship may be triggered by the interference instruction and / or a configuration related to reassociation of the reference signal resources. The specific implementation has been described in detail above and will not be repeated here.
