Description

Communication methods, devices, storage media and software products

[0001] This application claims priority to Chinese Patent Application No. 202411046567.2, filed with the China National Intellectual Property Administration on July 31, 2024, entitled "Communication Method, Apparatus, Storage Medium and Program Product", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, apparatus, storage medium, and program product. Background Technology

[0003] The conclusions reached at the 117th meeting of the 3GPP Radio Access Network Working Group 1 (RAN1#117) supported the separate reporting of channel state information (CSI) measurements for two types of symbols: subband full duplex (SBFD) symbols and non-subband full duplex (non-SBFD) symbols. For example, this includes indicating reporting configurations for each symbol type separately. It also considers that some instances may be on SBFD symbols while others are on non-SBFD symbols. CSI-RS resources are configured via the network to indicate on which symbol types the terminal should receive data from. Specifically, a time-domain symbol is called an SBFD symbol if it has at least one downlink (DL) subband and at least one uplink (UL) subband. A time slot is called an SBFD time slot if all symbols within it are SBFD symbols. In the SBFD scheme, a carrier is divided into multiple subbands, and the transmission directions of different subbands can be different. However, existing technologies do not clearly define how CSI-RS resources are used for other types of measurements in SBFD scenarios. Summary of the Invention

[0004] This application discloses a communication method, device, storage medium, and program product that can improve measurement accuracy.

[0005] Firstly, embodiments of this application provide a communication method. This method can be applied to a terminal side, such as a terminal or a communication / processing module within the terminal, or a circuit or chip in the terminal responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip), or a circuit or chip in the terminal responsible for processing functions (e.g., a graphics processing unit (GPU)). Taking the application of this method to a terminal as an example, in this method, the terminal receives configuration information from a network device. The configuration information is used to configure one or more reference signal resources. The configuration information includes configuration information for a first reference signal resource, wherein the instance corresponding to the first reference signal resource appears on a sub-band full-duplex SBFD symbol or a non-sub-band full-duplex non-SBFD symbol, and the first reference signal resource is any one of the one or more reference signal resources; or, the configuration information indicates measurement and / or reporting based on the SBFD symbol or non-SBFD symbol. Furthermore, the terminal measures the reference signal based on the configuration information.

[0006] In this embodiment, the terminal measures the reference signal based on the configuration information sent by the network device, enabling the terminal to determine the symbol type to be measured. This eliminates the possibility of cross-symbol type filtering during the measurement process, ensuring the accuracy of the measurement and the consistency of the signal-to-interference-plus-noise ratio (SINR) / reference signal received power (RSRP) at different points during the filtering process.

[0007] In one possible implementation, an instance of each of the one or more reference signal resources appears on the SBFD symbol or the non-SBFD symbol.

[0008] Alternatively, instances of some of the aforementioned reference signal resources may appear on SBFD symbols, while instances of other resources may appear on non-SBFD symbols, etc.

[0009] In one possible implementation, based on the configuration information, when a first portion of an instance corresponding to the second reference signal resource appears on the SBFD symbol and a second portion appears on the non-SBFD symbol, measurement and / or reporting are performed based on the SBFD symbol or the non-SBFD symbol, wherein the second reference signal resource is any one of the one or more reference signal resources. This ensures measurement accuracy and consistency of SINR / RSRP at different points during the filtering process.

[0010] In one possible implementation, the measurement of the reference signal is completed within a measurement time, which is determined based on the time interval and / or the number of instances of the second reference signal resource appearing on the SBFD symbol or the non-SBFD symbol.

[0011] In one possible implementation, when measuring the one or more reference signal resources on the SBFD symbol, it is determined that uplink UL data will not be transmitted on the SBFD symbol if one or more of the following conditions are met:

[0012] The one or more reference signal resources are used for radio link monitoring (RLM) measurements and the T310 timer is started; the one or more reference signal resources are used for RLM, beam failure detection (BFD), or candidate beam detection (CBD) measurements; the one or more reference signal resources are used for RLM, BFD, or CBD measurements and the network device indicates that the UL data will not be transmitted on the SBFD symbol; the one or more reference signal resources are used for neighbor cell measurements and the quality of the serving cell is lower than a first preset threshold and / or the quality of the neighbor cell is higher than a second preset threshold; the one or more reference signal resources are used for neighbor cell measurements and the UL service does not include signaling transmission or preset priority data; the one or more reference signal resources are used for neighbor cell measurements and the network device indicates that the UL data will not be transmitted on the SBFD symbol; the one or more reference signal resources are used for beam measurements and during transmission configuration indicator (TCI) switching or path-loss reference signal switching.

[0013] This avoids unnecessary triggering of link or beam failures due to untimely measurements. Alternatively, it facilitates timely measurement results for terminals at cell edges. Or, it prevents measurements from impacting critical UL services, prioritizing measurements for low-priority UL services to ensure timely mobility measurements. Or, it ensures the timely completion of important processes such as TCI handover or path-loss reference signal handover.

[0014] In one possible implementation, in the event of a UL conflict between the above-described measurement and dynamic scheduling, the measurement of the reference signal is completed within a measurement time, which is determined based on the time interval and / or the number of instances of the one or more reference signal resources appearing on the SBFD symbol.

[0015] In one possible implementation, the configuration information also indicates one or more of the following: not transmitting the UL data on the SBFD symbol, the first preset threshold corresponding to the quality of the serving cell, and / or the second preset threshold corresponding to the quality of the neighboring cell.

[0016] In one possible implementation, when measuring the one or more reference signal resources on the SBFD symbol, and when transmitting UL data on the SBFD symbol, the measurement of the reference signal is completed within the measurement time, wherein the measurement time is extended according to the number of instances of the one or more reference signal resources conflicting with dynamically scheduled ULs.

[0017] In one possible implementation, the configuration information further indicates the time-domain and / or frequency-domain configuration of the SBFD symbols of the neighboring cell transmitting the one or more reference signal resources; or, the configuration information further indicates that the time-domain and / or frequency-domain configuration of the SBFD of the neighboring cell is the same as that of the serving cell.

[0018] In this way, the terminal can correctly measure the reference signal resources transmitted by the neighboring cell using the time-frequency domain configuration information of the neighboring cell's SBFD.

[0019] Secondly, embodiments of this application provide a communication method. This method can be applied to the terminal side, such as a terminal or a communication / processing module within the terminal, or circuits or chips in the terminal responsible for communication functions (such as a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip), or circuits or chips in the terminal responsible for processing functions (such as a graphics processing unit (GPU). Taking the application of this method to a terminal as an example, in this method, the terminal receives configuration information from a network device, the configuration information being used to configure one or more reference signal resources. Furthermore, the terminal measures the reference signals based on the configuration information and predefined rules, the predefined rules including: measurement and / or reporting based on SBFD symbols or non-SBFD symbols.

[0020] In this embodiment, the terminal measures the reference signal based on configuration information and predefined rules, enabling the terminal to perform measurements and / or report based on SBFD symbols or non-SBFD symbols. This eliminates the possibility of cross-symbol type filtering during the measurement process, ensuring the accuracy of the measurement and the consistency of SINR / RSRP at different points during the filtering process.

[0021] Some possible implementations and beneficial effects of the second aspect can be found in the first aspect mentioned above, and will not be elaborated further.

[0022] In one possible implementation, according to the predefined rules, when the first part of the instance corresponding to the second reference signal resource appears on the SBFD symbol and the second part appears on the non-SBFD symbol, measurement and / or reporting are performed based on the SBFD symbol or the non-SBFD symbol, wherein the second reference signal resource is any one of the one or more reference signal resources.

[0023] Thirdly, embodiments of this application provide a communication method. This method can be applied to the network side, such as access network devices, modules (e.g., circuits, chips, or chip systems) within the access network devices, or logical nodes, logical modules, or software capable of implementing all or part of the functions of the access network devices. Taking the application of this method to an access network device as an example, in this method, the access network device sends configuration information, which is used to configure one or more reference signal resources. The configuration information includes configuration information for a first reference signal resource, wherein the instance corresponding to the first reference signal resource appears on a sub-band full-duplex SBFD symbol or a non-sub-band full-duplex non-SBFD symbol, and the first reference signal resource is any one of the one or more reference signal resources; or, the configuration information indicates measurement and / or reporting based on the SBFD symbol or non-SBFD symbol.

[0024] This example, which measures the reference signal based on the configuration information sent by the network device, can eliminate the possibility of cross-symbol type filtering during the measurement process, ensuring the accuracy of the measurement and the consistency of SINR / RSRP at different points during the filtering process.

[0028] In one possible implementation, the configuration information further indicates the time-domain and / or frequency-domain configuration of the SBFD symbols of the neighboring cell transmitting the one or more reference signal resources; or, the configuration information further indicates that the time-domain and / or frequency-domain configuration of the SBFD of the neighboring cell is the same as that of the serving cell.

Taking the application of this method to a terminal as an example, in this method, the terminal receives configuration information from a network device, the configuration information being used to configure one or more reference signal resources. Then, based on the configuration information, the terminal measures the reference signals, wherein, when measuring the one or more reference signal resources on an SBFD symbol, if one or more of the following conditions are met, it is determined that uplink UL data will not be transmitted on the SBFD symbol: the one or more reference signal resources are used for Radio Link Detection (RLM) measurement.

[0030] In one possible implementation, the measurement of the reference signal is completed within a measurement time, which is determined based on the time interval and / or the number of instances of the one or more reference signal resources appearing on the SBFD symbol.

[0031] In one possible implementation, the configuration information also indicates one or more of the following: not transmitting UL data on the SBFD symbol, the first preset threshold corresponding to the quality of the serving cell, and / or the second preset threshold corresponding to the quality of the neighboring cell.

Among these, 5G communication systems can also be referred to as new radio (NR) systems.

[0070] In a communication system, a network element can send signals to or receive signals from another network element. These signals can include information, signaling, or data. The term "network element" can also be replaced by an entity, network entity, device, communication equipment, communication module, node, communication node, etc. This application uses a network element as an example for description. For instance, a communication system may include at least one terminal and at least one access network device. The access network device can send downlink signals to the terminal, and / or the terminal can send uplink signals to the access network device. Furthermore, it is understood that if the communication system includes multiple terminals, these terminals can also exchange signals; that is, both the signal-sending network element and the signal-receiving network element can be a terminal.

[0071] Referring to Figure 1a, Figure 1a is a simplified schematic diagram of a wireless communication system provided in an embodiment of this application. As shown in Figure 1a, the wireless communication system includes a wireless access network 100. The wireless access network 100 can be a future wireless access network or an existing wireless access network (e.g., 5G or 4G). One or more communication devices (120a-120j, collectively referred to as 120) can be interconnected or connected to one or more network devices (110a, 110b, collectively referred to as 110) in the wireless access network 100. Figure 1a is only a schematic diagram; the wireless communication system may also include other devices, such as core network devices, wireless relay devices, and / or wireless backhaul devices, which are not shown in Figure 1a.

[0072] For example, in practical applications, this wireless communication system can simultaneously include multiple network devices (also called access network devices) and multiple communication devices. A network device can simultaneously serve one or more communication devices. A communication device can also simultaneously access one or more network devices.

Network equipment can also be mobile switching centers and devices that function as base stations in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, as well as devices that function as base stations in future communication systems.

The network device in this application can also be a logical node, logical module, or software capable of implementing all or part of the functions of a network device.

[0075] Network devices can be fixed or mobile. For example, base stations 110a and 110b are stationary and are responsible for wireless transmission and reception in one or more cells from communication device 120. The helicopter or drone 120i shown in Figure 1a can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station 120i. In other examples, the helicopter or drone (120i) can be configured as a communication device to communicate with base station 110b.

[0076] In this application, the communication device used to implement the above-mentioned network access functions can be an access network device, a network device with some access network functions, or a device capable of supporting the implementation of access network functions, such as a chip system, hardware circuit, software module, or hardware circuit plus software module. This device can be installed in the access network device or used in conjunction with the access network device. In the method of this application, the example of an access network device being used as the communication device to implement the access network device functions is described.

Communication devices can communicate with one or more core networks via network devices. Communication devices include handheld devices with wireless connectivity, other processing devices connected to wireless modems, or vehicle-mounted devices. Communication devices can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices. Communication devices can be widely used in various scenarios, such as cellular communication, device-to-device, vehicle-to-everything (V2X), point-to-point (P2P), machine-to-machine (M2M), machine-type communication (MTC), Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, drones, robots, remote sensing, passive sensing, positioning, navigation and tracking, autonomous delivery and mobility, etc.Examples of communication equipment 120 include: 3GPP standard user equipment (UE), fixed equipment, mobile equipment, handheld devices, wearable devices, cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal computers, smart books, vehicles, satellites, Global Positioning System (GPS) devices, drones, helicopters, aircraft, ships, remote control devices, smart home devices, industrial equipment, personal communication service (PCS) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), wireless network cameras, tablets, handheld computers, mobile internet devices (MIDs), wearable devices such as smartwatches, smart point-of-sale (POS) machines, customer-premises equipment (CPE), light UE, reduced capability UE (REDCAP UE), wireless terminals in industrial control, terminals in vehicle-to-everything (V2X) systems, and self-driving cars. Wireless terminals in various scenarios include those for driving, smart grids, transportation safety, smart cities (such as smart gas pumps, high-speed rail terminals), and smart homes (such as smart speakers, smart coffee machines, and smart printers). Communication equipment 120 can be wireless devices or devices installed on wireless devices, such as communication modules, modems, or chips. Communication equipment can also be vehicle-mounted devices, such as complete vehicle units, on-board modules, on-board chips, on-board units (OBUs), or telematics boxes (T-BOXs). Communication equipment can also be referred to as terminals, terminal equipment, UEs, mobile stations (MS), and mobile terminals (MTs). Communication equipment can also be used in future wireless communication systems. Communication equipment can be used in dedicated network equipment or general-purpose equipment. The embodiments of this application do not limit the specific technology or form of the communication equipment.

[0078] For example, a communication device can be used to act as a base station. For instance, a UE can act as a scheduling entity, providing sidelink signaling between UEs in V2X, D2D, or P2P, etc. As shown in Figure 1a, cellular phone 120a and car 120b communicate with each other using sidelink signaling. Cellular phone 120a communicates with smart home device 120e without relaying communication signals through base station 110b.

[0079] In this application, the communication device used to implement the functions of the communication equipment can be a terminal, a terminal having some of the functions of the aforementioned communication equipment, or a device capable of supporting the implementation of the functions of the aforementioned communication equipment, such as a chip system. This device can be installed in the terminal or used in conjunction with the terminal. In this application, the chip system can be composed of chips or include chips and other discrete components. The technical solutions provided in this application are described using a terminal or UE as an example of the communication device.

[0080] For example, a wireless communication system typically consists of cells, with a base station managing the cell and providing communication services to multiple mobile stations (MS) within it. The base station includes a base unit (BBU) and a remote unit (RRU). The BBU and RRU can be located in different places; for example, the RRU can be deployed remotely to a high-traffic area, while the BBU is located in a central equipment room. Alternatively, the BBU and RRU can be located in the same equipment room. The BBU and RRU can also be different components within the same rack. For example, a cell can correspond to a carrier or a member carrier.

[0081] It is understood that this application can be applied between network devices and communication devices, between network devices, or between communication devices, that is, between primary devices and secondary devices. The primary device can be a network device or a communication device. When the primary device is a network device, the secondary device can be another network device or a communication device. When the primary device is a communication device, the secondary device can be another communication device.

[0082] Communication between access network devices and terminals follows a specific protocol layer structure. This protocol layer structure can include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure can include the functions of protocol layers such as the radio resource control (RRC) layer, PDCP layer, radio link control (RLC) layer, medium access control (MAC) layer, and physical layer. Similarly, the user plane protocol layer structure can include the functions of protocol layers such as the PDCP layer, RLC layer, MAC layer, and physical layer. In one possible implementation, a service data adaptation protocol (SDAP) layer can be included above the PDCP layer.

[0083] For example, the protocol layer structure between the access network device and the terminal may also include an artificial intelligence (AI) layer for transmitting data related to AI functions.

[0084] Taking data transmission between access network devices and terminals as an example, data transmission needs to pass through user plane protocol layers, such as the SDAP layer, PDCP layer, RLC layer, MAC layer, and physical layer. The SDAP layer, PDCP layer, RLC layer, MAC layer, and physical layer can also be collectively referred to as the access layer. Based on the direction of data transmission, it is divided into sending and receiving; each of these layers is further divided into a sending part and a receiving part. Taking downlink data transmission as an example, after the PDCP layer obtains data from the upper layer, it transmits the data to the RLC layer and MAC layer. The MAC layer then generates a transport block, and finally, it is wirelessly transmitted through the physical layer. Data is encapsulated in corresponding ways at each layer. For example, data received by a layer from the upper layer is considered as the SDU of that layer. After encapsulation by that layer, it becomes a Protocol Data Unit (PDU) and is then passed to the next layer.

[0085] For example, the terminal may also have an application layer and a non-access layer. The application layer can be used to provide services to applications installed on the terminal. For instance, downlink data received by the terminal can be sequentially transmitted from the physical layer to the application layer, and then provided to the application by the application layer; or, the application layer can acquire data generated by the application and sequentially transmit the data to the physical layer for transmission to other communication devices. The non-access layer can be used to forward user data, such as forwarding uplink data received from the application layer to the SDAP layer or forwarding downlink data received from the SDAP layer to the application layer.

[0086] Access network equipment can include CUs and DUs. Multiple DUs can be centrally controlled by a single CU. As an example, the interface between the CU and DU can be called an F1 interface. The control plane (CP) interface can be F1-C, and the user plane (UP) interface can be F1-U. CUs and DUs can be distinguished according to the protocol layer of the wireless network: for example, the functions of the PDCP layer and above are located in the CU, and the functions of protocol layers below the PDCP layer (such as RLC and MAC layers) are located in the DU; or, for another example, the functions of the PDCP layer and above are located in the CU, and the functions of protocol layers below the PDCP layer are located in the DU.

[0087] It is understandable that the above division of CU and DU processing functions according to protocol layers is merely an example. Other division methods are also possible. For instance, CUs or DUs can be divided into those with more protocol layer functions, or they can be divided into those with partial protocol layer processing functions. In one design, some functions of the RLC layer and the protocol layer functions above the RLC layer are located in the CU, while the remaining functions of the RLC layer and the protocol layer functions below the RLC layer are located in the DU. In another design, the functions of CUs or DUs can be divided according to service type or other system requirements, such as latency. Functions that need to meet latency requirements are located in the DU, while functions that do not need to meet this latency requirement are located in the CU. In yet another design, the CU can also have one or more core network functions. For example, the CU can be located on the network side for convenient centralized management. In yet another design, the RU of the DU is remotely located. The RU has radio frequency functionality.

[0088] For example, DU and RU can be partitioned at the physical layer (PHY). For instance, DU can implement higher-level functions in the PHY layer, and RU can implement lower-level functions. Specifically, for transmission, the functions of the PHY layer may include adding cyclic redundancy check (CRC) codes, channel coding, rate matching, scrambling, modulation, layer mapping, precoding, resource mapping, physical antenna mapping, and / or radio frequency (RF) transmission functions. For reception, the functions of the PHY layer may include CRC, channel decoding, rate matching de-scrambling, demodulation, layer mapping de-mapping, channel detection, resource demapping, physical antenna demapping, and / or RF reception functions. The higher-level functions in the PHY layer may include a subset of the PHY layer's functions, for example, functions closer to the MAC layer, while the lower-level functions in the PHY layer may include another subset of the PHY layer's functions, for example, functions closer to the RF functions. For example, higher-level functions in the PHY layer may include adding CRC codes, channel coding, rate matching, scrambling, modulation, and layer mapping, while lower-level functions in the PHY layer may include precoding, resource mapping, physical antenna mapping, and radio frequency transmission functions; or, higher-level functions in the PHY layer may include adding CRC codes, channel coding, rate matching, scrambling, modulation, layer mapping, and precoding, while lower-level functions in the PHY layer may include resource mapping, physical antenna mapping, and radio frequency transmission functions.

[0089] For example, the functionality of a CU can be implemented by a single entity or by different entities. For instance, the functionality of the CU can be further divided, separating the control plane and user plane and implementing them through different entities: a control plane CU entity (i.e., the CU-CP entity) and a user plane CU entity (i.e., the CU-UP entity). These CU-CP and CU-UP entities can be coupled with a DU to jointly complete the functions of the access network device.

[0090] In the above architecture, signaling generated by the CU can be sent to the terminal via the DU, or signaling generated by the terminal can be sent to the CU via the DU. For example, signaling from the RRC or PDCP layer will eventually be processed into physical layer signaling and sent to the terminal, or it can be transformed from received physical layer signaling. Under this architecture, the RRC or PDCP layer signaling can be considered to be sent via the DU, or via the DU and RU.

[0091] For example, any one of DU, CU, CU-CP, CU-UP, and RU can be a software module, a hardware structure, or a combination of software and hardware structures, without limitation. The different entities can exist in different forms, without limitation. For example, DU, CU, CU-CP, and CU-UP are software modules, and RU is a hardware structure. These modules and the methods they execute are also within the scope of protection of this application.

[0092] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an O-RAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU.

[0093] It should be understood that the number and type of each device in the communication system shown in Figure 1a are for illustrative purposes only, and this application is not limited thereto. In actual applications, the communication system may include more terminals, more access network devices, and other network elements, such as core network devices and / or network elements used to implement artificial intelligence functions.

[0094] It is understood that all or part of the functions implemented by one or more of the terminals, access network devices, core network devices, or network elements used to implement artificial intelligence functions can be virtualized, that is, implemented through one or more of dedicated or general-purpose processors and corresponding software modules. Among these, the terminals and access network devices involve air interface transmission, and the transmit and receive functions of this interface can be implemented in hardware. Core network devices, such as operation administration and maintenance (OAM) network elements, can also be virtualized. For example, one or more of the functions of the virtualized terminals, access network devices, core network devices, or network elements used to implement artificial intelligence functions can be implemented by cloud devices, such as cloud devices in over-the-top (OTT) systems.

[0095] The method provided in this application can be used for communication between access network devices and terminals, or for communication between other communication devices, such as communication between macro base stations and micro base stations in a wireless backhaul link, or communication between two terminals in a sidelink (SL), etc., without limitation.

[0096] In this application, the phrase "sending information to... (e.g., a terminal)" or the related illustrations in the accompanying drawings can be understood as the destination of the information being the terminal. This can include sending information directly or indirectly to the terminal. Similarly, the phrase "receiving information from... (e.g., a terminal)" or "receiving information from... (e.g., a terminal)" or the related illustrations in the accompanying drawings can be understood as the source of the information being the terminal. This can include receiving information directly or indirectly from the terminal. Information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be interpreted similarly, and will not be elaborated further here.

[0097] Figure 1b illustrates an example diagram of an O-RAN system according to this application. The O-RAN system may include other components besides those shown in Figure 1b. As shown in Figure 1b, the access network device (RAN, for example, may be an eNB, gNB, or next-generation access network device) communicates with the core network (CN) via a backhaul link and with the user equipment (UE) via an air interface.

[0098] For example, the baseband unit (BBU) in the access network equipment communicates with the core network via a backhaul link, and the radio frequency unit (RU) in the access network equipment communicates with at least one user interface (UE) via an air interface. The BBU communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0099] The BBU includes at least one control unit (CU) and at least one distributed unit (DU), which can communicate via at least one midhaul link.

[0100] Figure 1c illustrates a network element functional division and protocol layer structure diagram for an O-RAN device according to this application. In some examples, the CU is a logical node carrying the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU connects to network nodes such as the core network through interfaces, which may be interfaces such as E2 interfaces. Optionally, the CU may have some functions of the core network. The CU (e.g., the PDCP layer and higher layers) connects to the DU (e.g., the RLC layer and lower layers) through interfaces, which may be interfaces such as F1 interfaces. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, and in some examples, the signaling procedures of F1 are defined. The F1 interface supports the control plane F1-C and the user plane F1-U.

[0101] In some examples, the CU can be split into a centralized unit-control plane (CU-CP) and a centralized unit-user plane (CU-UP). The CU-CP is a logical node carrying the RRC layer and the packet data convergence protocol control plane (PDCP-C) layer, used to implement the CU's control plane functions. The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) elements, such as the access and mobility management function (AMF) in a 5G system. The AMF element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. The CU-UP is a logical node carrying the SDAP layer and the packet data convergence protocol user plane (PDCP-U) layer, used to implement the CU's user plane functions. The CU-UP can interact with network elements in the core network used to implement user plane functions. In the core network, network elements used to implement user plane functions, such as the UPF in a 5G system, are responsible for forwarding and receiving data in terminal devices. The above configuration of CU and DU is merely an example; the functions of CU and DU can be configured as needed. For example, CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For instance, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of CU or DU can be divided according to service type or other system requirements, such as by latency, placing functions that need to meet low latency requirements in the DU and functions that do not need to meet such latency requirements in the CU.

[0102] In some examples, a DU is a logical node that carries the radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which may be fronthaul interfaces. In some examples, the higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0103] In some examples, the RU is a logical node that carries both lower physical layer (lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the lower PHY includes PHY processing functions such as fast Fourier transform (FFT), inverse fast Fourier transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0104] The DU and RU can be co-located or separate. The DU and RU exchange control plane and user plane information via a fronthaul link through a lower layer split-control, user, and synchronization (LLS-CUS) interface. LLS-CUS may include LLS-C and LLS-U interfaces, respectively providing the control plane (C-plane) and user plane (U-plane). In some examples, the control plane (C-plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via an LLS-M interface on the fronthaul link; the management plane (M-plane) refers to non-real-time management operations between the DU and RU.

[0105] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0106] Figure 1d illustrates a block diagram of an example of a baseband hardware implementation according to this application, which can be implemented using a processing system including one or more processors. Processors include microprocessors (e.g., x86, advanced RISC machines (ARM)), microcontrollers, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), GPUs, programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to various functions. In other words, the processor used in the baseband can be used to implement the processes described below and any one or more of those processes.

[0107] A processing system can be implemented using a bus architecture, typically represented by a bus. A bus can include any number of interconnect buses and bridges, depending on the specific application and overall design constraints of the processing system. The bus communicatively couples various circuits together, including one or more processors (typically represented by a processor), memory, and computer-readable media (typically represented by a computer-readable media). The bus can also link various other circuits, such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further. The bus interface provides the interface between the bus and transceivers, and between the bus and the interface.

[0108] A transceiver provides a communication interface or means for communicating with various other devices via a wireless transmission medium. The transceiver may be coupled to an antenna array, and the transceiver and antenna array may be used together for communication with a corresponding network type. At least one interface (e.g., a network interface and / or a user interface) provides a communication interface or means for communication via an internal bus or via an external transmission medium.

[0109] The processor is responsible for managing the bus and general processing, including executing software stored on a computer-readable medium. When the processor executes the software, the software causes the processing system to perform the various functions described below for any particular device.

[0110] The functions that can be implemented by the processor, memory, and computer-readable medium include: encoding, decoding, rate matching, rate matching dematching, scrambling, descrambling, modulation, demodulation, layer mapping, FFT, IFFT, inverse discrete fourier transform (IDFT), precoding, resource element (RE) mapping, channel equalization, RE demapping, digital beamforming (BF), adding cyclic prefix (CP), removing CP, etc.

[0111] Figure 1e illustrates a common RAN chip architecture, divided into CU, DU, and RU. The CU is a platform that performs upper-layer L2 and L3 functions. The midhaul and backhaul interfaces are used to carry traffic between the CU and DU, as well as between the CU and the core network. The DU performs L1 and some L2 functions, while the RU performs L1 computation and RF digital functions. The fronthaul and backhaul interfaces are used to carry traffic between the RU and DU, as well as between the CU and DU. An integrated DU includes the functions of both the DU and RU.

[0112] The CU / DU hardware includes a chassis platform, motherboard, peripherals, and cooling system. The motherboard contains processing units, memory, internal I / O interfaces, and external connection ports. Its hardware accelerator is designed with interfaces, and hardware functional components include: storage for software, hardware, and system debugging interfaces, and a single-board management controller.

[0113] DU systems are typically implemented using multi-core processors and one or more hardware accelerators. Parts of the DU protocol stack can be implemented in software running on the multi-core processor, while computationally intensive L1 and L2 functions can be offloaded to FPGA / GPU-based hardware accelerators; alternatively, all L1 functions can be offloaded to FPGA / GPU-based hardware accelerators, while other protocol stack components are implemented in software running on the processor; or the entire protocol stack can be implemented in software running on the processor. Hardware accelerators support interconnection with x86 or non-x86 processors. Similarly, accelerators have multi-channel PCIe interfaces pointing to the CPU and external connections via GbE.

[0114] The RU comprises three parts: the O-RAN processing unit (OPU), which receives eCPRI frames from the O-RAN fronthaul and performs fronthaul interface operations, the lowest level L1 (encoding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The OPU can be implemented as a CPU, FPGA, or ASIC. The O-RU's digital processing unit (DPU) performs synchronization, digital downconversion (DDC) in the UL, and digital upconversion (DUC), CFR, and DPD in the downlink (DL), improving power amplifier efficiency by reducing PAPR / ACLR at the RF front-end; the DPU can be implemented as an FPGA or application-specific integrated circuit (ASIC). The O-RU's RF processing unit includes a transceiver module, up / down converters, power amplifiers (PA), low-noise amplifiers (LNA), and Tx / Rx filters. All conversions between the analog and digital domains (DAC and ADC) (e.g., frequency conversion using RF sampling, up-conversion and down-conversion, and mixing of intermediate frequency (IF) and local oscillator (LO)) are performed within the transceiver module. Note that physical and logical partitions within the RF processing unit do not require specific boundaries.

[0115] The following is an introduction to the technical terms used in this application.

[0116] 1. SBFD

[0117] 5G New Radio (NR) wireless communication systems are deployed in mid-to-high frequency bands, achieving high data rates and low latency through the use of large bandwidth. In existing Time Division Duplex (TDD) systems, the downlink (DL) typically occupies the majority of time resources, resulting in coverage imbalance between the DL and uplink (UL). Compared to Frequency Division Duplex (FDD) systems, TDD systems have poorer uplink coverage and higher latency. To address the uplink coverage and latency issues in TDD systems, 3GPP proposed the Subband Full-Duplex (SBFD) scheme. In the SBFD scheme, a carrier is divided into multiple subbands, and the transmission directions of different subbands can be different. A typical SBFD scheme is shown in Figure 2, where a carrier is divided into three subbands: the middle subband is uplink, and the top and bottom subbands are downlink.

[0118] In the SBFD scheme, base stations can simultaneously transmit and receive on SBFD symbols using different frequency domain resources (subbands). Currently, the R19 standard discussion has decided to adopt a technical approach of "full-duplex subband on the network device side and half-duplex on the terminal device side." Full-duplex subband on the network device side means that the network device can simultaneously transmit on the downlink subband and receive on the uplink subband on the SBFD symbol. Half-duplex subband on the terminal device side means that the terminal device can only receive on the downlink subband or transmit on the uplink subband on the SBFD symbol, and cannot receive or transmit simultaneously. Under the SBFD scheme, the available uplink transmission resources for the terminal device increase, which can effectively improve uplink coverage and reduce uplink latency.

[0119] A symbol is called an SBFD symbol if it has at least one DL subband and at least one UL subband. A slot is called an SBFD slot if all symbols within it are SBFD symbols. In Figure 2, the TDD configuration for five consecutive slots is DDDSU, where the second and third DL slots are configured as SBFD slots.

[0120] 2. Wireless Link Monitoring (RLM) / Beam Failure Detection (BFD) / Alternate Beam Detection (CBD) Measurement

[0121] RLM measurement is performed by the terminal on a network-specified reference signal to monitor the quality of the wireless link. The measurement results determine the reception performance of the physical downlink control channel (PDCCH) under the current link quality. If the reception performance (measured by the block error ratio (BLER)) is below a certain threshold, the terminal records an out-of-sync (OOS) event. When the number of OOS events exceeds a certain threshold, the terminal starts a T310 timer. When the T310 timer expires, it triggers RRC reconstruction. If the PDCCH reception performance under the current link quality is above a certain threshold, the terminal records an in-sync (IS) event. If the number of IS events exceeds a certain threshold before the T310 timer expires, the terminal considers the link restored.

[0122] Similar to RLM measurement, BFD measurement is performed by the terminal on a reference signal specified by the network to monitor the quality of the current serving beam. The measurement results determine the reception performance of the Physical Downlink Control Channel (PDCCH) under the current beam quality. If the reception performance (measured by the Block Error Rate (BLER)) is below a certain threshold, the terminal will record an Out-of-Sight (OOS). When the number of OOS exceeds a certain threshold within a certain time period, beam failure will be triggered, which in turn triggers CBD measurement.

[0123] CBD measurement is the process by which a terminal searches for a new available beam by measuring a reference signal specified by the network after a beam failure is triggered. When the terminal finds a reference signal whose Layer 1 Reference Signal Received Power (L1-RSRP) is higher than a certain threshold, it informs the network of the found reference signal through random access channel (RACH) or other procedures.

[0124] 3. L3 mobility measurement

[0125] In NR, terminals can perform mobility measurements on CSI-RS resources transmitted by neighboring cells. The terminal reports the measurement results to the network via L3 signaling, and the network typically uses these results for mobility (e.g., cell handover) decisions. The serving cell, in its measurement configuration, indicates the cell containing the CSI-RS resource to be measured, its frequency domain location (bandwidth and starting resource block (RB)), time domain location (period and offset), and associated synchronization signal and physical broadcast channel (PBCH) block (SSB). The time domain location is configured relative to the timing of neighboring cells. If associated SSB is configured, the terminal needs to detect its associated SSB before measuring a CSI-RS resource; the CSI-RS resource is only measured if an associated SSB is detected.

[0126] 4. L1 beam measurement

[0127] In NR, terminals can perform beam measurements on CSI-RS resources transmitted by the serving cell. The terminal reports the measurement results to the network via L1 signaling. Typically, the network uses these measurement results to select the transmission beam within the serving cell for scheduling the terminal. The serving cell will indicate information such as the frequency domain location (bandwidth and starting RB) and time domain location (period and offset) of the CSI-RS resource to be measured in its measurement configuration.

[0128] The architecture of the embodiments of this application has been described above. The methods of the embodiments of this application will be described in detail below.

[0129] Referring to Figure 3, a flowchart illustrating a communication method provided in an embodiment of this application is shown. Optionally, this method can be applied to the aforementioned communication system, such as the communication system shown in Figure 1a. The communication method shown in Figure 3 may include steps 301-302, as follows:

[0130] 301. The network device sends configuration information to the terminal, which is used to configure one or more reference signal resources. The configuration information includes configuration information for a first reference signal resource, wherein an instance corresponding to the first reference signal resource appears on an SBFD symbol or a non-SBFD symbol, and the first reference signal resource is any one of the one or more reference signal resources. Alternatively, the configuration information indicates that measurement and / or reporting is performed based on the SBFD symbol or non-SBFD symbol. Accordingly, the terminal receives the configuration information.

[0131] An instance can be understood as a single occurrence of a periodic resource. For example, if the period of a CSI-RS resource is 20ms, then multiple instances of this resource can occur at positions k, k+20, k+40, k+60, k+80… where k is the temporal position of the first occurrence.

[0132] The instance corresponding to the first reference signal resource appears on either SBFD symbols or non-SBFD symbols. This can be understood as either the instance corresponding to the first reference signal resource only appearing on SBFD symbols, or the instance corresponding to the first reference signal resource only appearing on non-SBFD symbols. As shown in Figure 4, if the instance of a resource appears on both non-SBFD symbols and SBFD symbols, then this resource cannot be used as the aforementioned first reference signal resource (as shown by instance x in Figure 4).

[0133] Understandably, the instances corresponding to the first reference signal resource appear on SBFD symbols or non-SBFD symbols. This can mean that instances corresponding to all resources (each resource) within the one or more reference signal resources appear on the same symbol (SBFD symbol or non-SBFD symbol). Alternatively, instances corresponding to some resources within the one or more reference signal resources may appear on SBFD symbols, while instances corresponding to other resources may appear on non-SBFD symbols, and so on. For example, the one or more reference signal resources include resource 1 and resource 2. Both resource 1 and resource 2 appear on SBFD symbols. Alternatively, both resource 1 and resource 2 appear on non-SBFD symbols. Or, resource 1 appears on SBFD symbols, and resource 2 appears on non-SBFD symbols.

[0134] The instances corresponding to the first reference signal resource mentioned above are all instances corresponding to that first reference signal resource.

[0135] For example, for one CSI-RS resource used for RLM / BFD / CBD measurements, the network device guarantees that all its instances appear only on SBFD symbols; for another CSI-RS resource used for RLM / BFD / CBD measurements, the network device guarantees that all its instances appear only on non-SBFD symbols. Alternatively, for all CSI-RS resources used for RLM / BFD / CBD measurements, the network device guarantees that all its instances appear only on non-SBFD symbols. For an introduction to RLM / BFD / CBD measurements, please refer to the foregoing descriptions; they will not be repeated here.

[0136] For example, for any CSI-RS resource used for L3 mobility measurement, the network device guarantees that all instances appear only on the non-SBFD symbols of the neighboring cells that sent that resource. For an introduction to L3 mobility measurement, please refer to the aforementioned records, which will not be repeated here.

[0137] The above configuration information indicates that measurements and / or reporting are based on the SBFD symbol or the non-SBFD symbol. It can be understood as an indication for a single resource (per-resource indication) or an indication for all resources (per-UE indication), etc. This scheme does not impose any restrictions on this.

[0138] In one possible implementation, when a first portion of an instance corresponding to a second reference signal resource appears on the SBFD symbol and a second portion appears on the non-SBFD symbol, measurement and / or reporting are performed based on the SBFD symbol or the non-SBFD symbol. The second reference signal resource can be any one of the one or more reference signal resources.

[0139] For example, for a CSI-RS resource used for RLM / BFD / CBD measurements, if some instances are on SBFD symbols and some instances are on non-SBFD symbols, the terminal only measures the instances of that resource appearing on the specific type of symbols. For instance, if the configuration information indicates that the resource is measured and / or reported based on SBFD symbols, the terminal only measures the instances of that resource appearing on SBFD symbols; or if the configuration information indicates that the resource is measured and / or reported based on non-SBFD symbols, the terminal only measures the instances of that resource appearing on non-SBFD symbols.

[0140] For example, for multiple CSI-RS resources used for RLM / BFD / CBD measurements, each resource may have some instances on SBFD symbols and some instances on non-SBFD symbols. The terminal will only measure the instances of these resources appearing on the specific type of symbols. For instance, if the configuration information above instructs the terminal to perform measurements and / or reporting based on SBFD symbols, the terminal will only measure the instances of these resources appearing on SBFD symbols; or if the configuration information above instructs the terminal to perform measurements and / or reporting based on non-SBFD symbols, the terminal will only measure the instances of these resources appearing on non-SBFD symbols.

[0141] For example, for three CSI-RS resources used for RLM / BFD / CBD measurements, if all instances of resource 1 are on SBFD symbols, all instances of resource 2 are on non-SBFD symbols, and some instances of resource 3 are on SBFD symbols and some are on non-SBFD symbols, then the terminal will only measure the instances of these resources appearing on symbols of specific types. For instance, if the above configuration information instructs the terminal to perform measurements and / or reporting based on non-SBFD symbols, then the terminal will only measure the instances of resources 2 and 3 appearing on non-SBFD symbols.

[0142] Optionally, for a CSI-RS resource used for L3 mobility measurement, the network device indicates the symbol type corresponding to (per-resource or per-measurement reporting), for example, the network device indicates measurement reporting for non-SFBD symbols. Alternatively, the network device indicates measurement reporting for SBFD symbols and non-SBFD symbols separately, etc., and this scheme does not restrict this.

[0143] In one possible implementation, for any CSI-RS resource used for L3 mobility measurement, the network device indicates the time-domain and / or frequency-domain configuration of the SBFD of the neighboring cell transmitting the resource, or indicates that the time-domain and / or frequency-domain configuration of the SBFD of the neighboring cell is the same as that of the serving cell. For example, the network device indicates the period of occurrence of the inner SBFD symbols of the neighboring cell and the starting time-domain position of the SBFD symbols within the period, and the frequency-domain position of the inner uplink subband and downlink subband of the neighboring cell. Alternatively, the network device may indicate that the time-domain and / or frequency-domain configuration of the SBFD of the neighboring cell is the same as that of the serving cell using 1 bit. In this way, the terminal can determine the time-domain configuration of the SBFD of the neighboring cell, and thus determine whether the CSI-RS resource transmitted by the neighboring cell is located on an SBFD symbol. If the terminal determines that the CSI-RS resource is located on an SBFD symbol of the neighboring cell, the terminal can determine the measurement bandwidth based on the frequency-domain configuration of the SBFD of the neighboring cell, for example, measuring only the portion of the resource located within the downlink subband of the neighboring cell.

[0144] This example, through configuration information, allows the terminal to determine the symbol type for measurement, eliminating the possibility of cross-symbol type filtering during the measurement process. This ensures measurement accuracy and consistency of the signal-to-interference-plus-noise ratio (SINR) / reference signal received power (RSRP) at different points during filtering. For instance, in a typical implementation, CSI-RS for RLM / BFD / CBD measurements can be restricted to non-SBFD symbols, accurately reflecting the true link quality without CLI and avoiding false link or beam failures due to CLI interference.

[0145] 302. The terminal measures the reference signal based on the configuration information.

[0146] In one possible implementation, for a CSI-RS resource used for measurement, if all its instances are on a symbol of a certain type, the terminal determines the measurement time based on the periodicity of the CSI-RS resource's occurrence. This measurement could be, for example, a CSI-RS resource used for RLM / BFD / CBD measurements, L3 mobility measurements, or L1 beamforming measurements.

[0147] In another possible implementation, when the first part of the instance corresponding to the second reference signal resource appears on the SBFD symbol and the second part appears on the non-SBFD symbol, the terminal performs measurement and / or reporting based on the SBFD symbol or the non-SBFD symbol.

[0148] In one possible implementation, the terminal completes the measurement of the reference signal within a measurement time, which is determined based on the time interval and / or the number of instances of the second reference signal resource appearing on the SBFD symbol or the non-SBFD symbol. For example, this measurement time T... measure It can be represented as: T s =t s+1 -t s ifs <S; T s =X ifs=S;

[0149] Where S is an integer greater than or equal to 1, representing the number of sample points measured, and t s+1 and t s X represents the (s+1)th and sth times the resource appears on the SBFD symbol or non-SBFD symbol. X is a number greater than or equal to 0, representing the processing time for each sample point. For example, X = 1ms or X is the length of the slot in ms.

[0150] In one possible implementation, for a CSI-RS resource used for L3 mobility measurement, if some instances are on SBFD symbols of the neighboring cell transmitting the resource and some instances are on non-SBFD symbols, the terminal measures only or separately the instances of the resource appearing on specific types of symbols, and determines the measurement time based on the time interval or the number of instances of the resource appearing on specific types of symbols. For example, the terminal only measures instances of the resource appearing on non-SBFD symbols. Optionally, for the measurement of instances appearing on SBFD symbols, the measurement time is determined based on the time interval and / or the number of instances of the CSI-RS resource appearing on SBFD symbols. For the measurement of instances appearing on non-SBFD symbols, the measurement time is determined based on the time interval and / or the number of instances of the CSI-RS resource appearing on non-SBFD symbols, etc.

[0151] In one possible implementation, for a CSI-RS resource used for L3 mobility measurement, if the resource is located on the SBFD symbol of a neighboring cell that transmitted the resource, or on the SBFD symbol corresponding to the resource, the terminal measures the resource at a frequency domain location where it is available for measurement. For example, the resource is located within the bandwidth of the neighboring cell's DL subband. This allows the terminal to avoid measuring the portion of the resource located within the uplink subband. Measuring the entire bandwidth of the resource would lead to measurement errors because the neighboring cell does not map the resource within the uplink subband.

[0152] In one possible implementation, for a CSI-RS resource used for L1 beam measurement, if some instances are on SBFD symbols of the neighboring cell transmitting the resource and some instances are on non-SBFD symbols, the terminal measures only or separately the instances of the resource appearing on specific types of symbols, and determines the measurement time based on the time interval or the number of instances of the resource appearing on specific types of symbols. Optionally, for measurements of instances appearing on SBFD symbols, the measurement time is determined based on the time interval and / or the number of instances of the CSI-RS resource appearing on SBFD symbols. For measurements of instances appearing on non-SBFD symbols, the measurement time is determined based on the time interval and / or the number of instances of the CSI-RS resource appearing on non-SBFD symbols.

[0153] In one possible implementation, when the UE performs measurements on at least one CSI-RS resource on an SBFD symbol (the specific conditions are not limited, for example, all instances of the resource are on SBFD symbols, or some instances of the resource are on SBFD symbols and some instances are on non-SBFD symbols, and the network device is configured to report measurements for SBFD symbols, etc.), if at least one instance of the CSI-RS resource conflicts with dynamically scheduled uplink UL data transmission, the terminal does not transmit UL data but performs CSI-RS. Optionally, in this case, the measurement time does not consider the impact of conflicts with dynamically scheduled UL. That is, when determining the measurement time, both instances that do not conflict and instances that conflict are considered.

[0154] Furthermore, CSI-RS is determined to be performed without transmitting UL data on the SBFD symbol if one or more of the following conditions are met:

[0155] The one or more reference signal resources are used for Radio Link Monitoring (RLM) measurements and T310 timer is started; the one or more reference signal resources are used for RLM, Beam Failure Detection (BFD) or Alternate Beam Detection (CBD) measurements; the one or more reference signal resources are used for RLM, BFD or CBD measurements and the network device indicates not to transmit the UL data on the SBFD symbol; the one or more reference signal resources are used for neighbor cell measurements and the quality of the serving cell is lower than a first preset threshold and / or the quality of the neighbor cell is higher than a second preset threshold; the one or more reference signal resources are used for neighbor cell measurements and the UL service does not include signaling transmission or preset priority data (such as high priority data); the one or more reference signal resources are used for neighbor cell measurements and the network device indicates not to transmit the UL data on the SBFD symbol; the one or more reference signal resources are used for beam measurements and when the transmission configuration indicates TCI switching or path-loss reference signal switching.

[0156] Accordingly, when one or more of the reference signal resources exist on the SBFD symbol, the network device does not schedule UL data on the SBFD symbol if one or more of the above conditions are met.

[0157] In other words, when a conflict occurs, the UE will not send UL data but will perform CSI-RS measurements if the above conditions are met. Specifically, this applies to RLM measurements and the T310 timer is started, i.e., during in-sync measurements. This avoids unnecessary triggering of link or beam failures due to untimely measurements. The first and / or second preset thresholds can be indicated by the configuration information. Optionally, the network device indicates preset thresholds for the quality of the serving cell and / or neighboring cells to resolve conflicts between CSI-RS measurements on the SBFD symbol of the serving cell and dynamically scheduled UL. For example, the terminal determines not to send UL based on the quality of the serving cell and / or neighboring cells and the preset thresholds indicated by the network device. Optionally, the quality of the neighboring cell is determined based on measurements on the associated SSB corresponding to the resource. This facilitates timely measurement results for the terminal at the cell edge. The resource is used for neighboring cell measurements, and the UL service does not include signaling transmission or high-priority data; that is, when the UL service does not include signaling transmission or high-priority data, UL data is not sent. For example, this signaling transmission includes reporting measurement results. Another example is that the terminal determines not to send UL based on the UL service. This avoids the impact of measurements on important UL services, while prioritizing measurements when UL services have low priority to ensure timely mobility measurements. Yet another example is that if CSI-RS measurements occur during TCI handover or path-loss reference signal handover, the terminal performs CSI-RS without sending UL, and the measurement time does not consider the number of instances conflicting with dynamically scheduled ULs. This ensures that important processes such as TCI handover or path-loss reference signal handover are completed in a timely manner.

[0158] In one possible implementation, when the aforementioned conflict occurs, the measurement time is determined based on the time interval and / or the number of instances of the resource appearing on the SBFD symbol. For a description of this part, please refer to the foregoing records, which will not be repeated here.

[0159] In one possible implementation, when measuring the one or more reference signal resources on the SBFD symbol, if at least one instance of the CSI-RS resource conflicts with a dynamically scheduled UL transmission, for example, if the aforementioned condition is not met, UL data is transmitted on the SBFD symbol without performing CSI-RS measurements. Optionally, the measurement of the reference signal is completed within the measurement time, wherein the measurement time is extended according to the number of instances where the one or more reference signal resources conflict with the dynamically scheduled UL.

[0160] For example, the measurement time T of L1 beam measurement measure It can be represented as: T measure =max(T)Report ,ceil((M+L1)*P)*T CSI-RS );

[0161] Among them, T Report The reporting period configured for the network, where M is the number of measured samples and L1 is the time interval. measure The number of instances of conflicts between internal CSI-RS resources and dynamically scheduled UL, where P is a relaxation factor considering conflicts between CSI-RS resources and measurement gaps, etc., and T CSI-RS The period for CSI-RS resources. L1≤L1 max L1 max This is the maximum number of extensions predefined by the standard. ceil((M+L1)*P) represents rounding over (M+L1)*P.

[0162] For example, during out-of-sync measurements (before T310 startup), the terminal sends UL data. Similarly, during BFD measurements, the terminal sends UL data. Furthermore, the terminal determines whether to send UL based on the quality of the serving cell and / or neighboring cells, and preset thresholds indicated by the network equipment. Or, the terminal determines whether to send UL based on the UL service. For instance, when the UL service is signaling transmission (including measurement reporting) or high-priority data, UL is sent first; otherwise, CSI-RS measurements are sent first.

[0163] It should be noted that the conditions shown above in the event of a conflict are merely examples, and this solution does not impose any restrictions on them.

[0164] Furthermore, the above example, which can at least be applied to RLM / BFD / CBD measurements, defines the method for the terminal to determine the symbol type for RLM / BFD / CBD measurements and the corresponding measurement time. By restricting network implementation, network configuration, or specifying terminal behavior, the possibility of cross-symbol type filtering during RLM / BFD / CBD measurements is eliminated, ensuring the accuracy of RLM / BFD / CBD measurements and the consistency of SINR / RSRP at different points during filtering. In a typical implementation, CSI-RS for RLM / BFD / CBD measurements can be restricted to non-SBFD symbols, accurately reflecting the true link quality in the absence of cross-link interference (CLI), and avoiding false link or beam failures due to CLI. This example also defines the priority of RLM / BFD / CBD measurements and dynamically scheduled UL conflicts. Prioritizing measurements allows the terminal to judge link quality more promptly. In particular, when a link problem or beam failure is detected, UL may not be received correctly, and timely restoration of the link or beam is more important than UL. Prioritizing in-sync measurement and CBD measurement is beneficial for timely restoration of the link or beam and avoids unnecessary triggering of link failure or beam failure.

[0165] Furthermore, the above example, which is at least applicable to L3 mobility measurement, defines a method for a terminal to determine whether the CSI-RS resources used for L3 mobility measurement are located on SBFD symbols in neighboring cells. It further specifies a method for a terminal to determine available resources in the frequency domain when a resource is located on an SBFD symbol in a neighboring cell, enabling the terminal to correctly measure the CSI-RS resources of neighboring cells with SBFD enabled. This example also defines a method for a terminal to determine the symbol type for L3 mobility measurement and its corresponding measurement time, enabling the terminal to measure for a specific symbol type of a neighboring cell, or to measure for different symbol types of neighboring cells separately. This example also defines the priority and corresponding measurement time when L3 mobility measurement and dynamic scheduling UL conflict, clarifying the terminal's transmission behavior.

[0166] Furthermore, the above example, which can at least be applied to L1 beam measurements, defines the measurement time for the terminal to perform L1 beam measurements on different types of symbols. This example also defines the priority when L1 beam measurements conflict with dynamically scheduled UL. Prioritizing measurements during special procedures such as TCI switching or path-loss reference signal switching helps the terminal complete these procedures more promptly, avoiding increased latency due to dynamic UL that could affect subsequent DL or UL data.

[0167] In this embodiment, the terminal measures the reference signal based on the configuration information sent by the network device, thereby enabling the terminal to determine the symbol type to be measured. This eliminates the possibility of cross-symbol type filtering during the measurement process, ensuring the accuracy of the measurement and the consistency of SINR / RSRP at different points during the filtering process.

[0168] Referring to Figure 5, a flowchart illustrating another communication method provided in an embodiment of this application is shown. Optionally, this method can be applied to the aforementioned communication system, such as the communication system shown in Figure 1a. The communication method shown in Figure 5 may include steps 501-502, as follows:

[0169] 501. The network device sends configuration information to the terminal, which is used to configure one or more reference signal resources. Accordingly, the terminal receives the configuration information.

[0170] 502. The terminal measures the reference signal based on the configuration information and predefined rules. The predefined rules include: measuring and / or reporting based on SBFD symbols or non-SBFD symbols.

[0171] The difference between this example and the embodiment shown in Figure 3 is that this example does not require configuration information, but instead determines the measurement and / or reporting based on the set symbols according to predefined rules.

[0172] In one possible implementation, measurement and / or reporting are predefined based on non-SBFD symbols. Alternatively, measurement and / or reporting are predefined based on SBFD symbols.

[0173] In another possible implementation, the symbol can be determined based on predefined conditions. For example, when an SSB is available for measurement, the UE only uses the instance of that CSI-RS resource on the SBFD symbol for measurement. Similarly, when at least one CSI-RS resource that appears only on non-SBFD symbols is available for measurement, the UE only uses the instance of that CSI-RS resource on the SBFD symbol for measurement, and so on. Of course, other conditions are also possible, and this scheme does not limit them.

[0174] In one possible implementation, when a first portion of an instance corresponding to a second reference signal resource appears on the SBFD symbol and a second portion appears on the non-SBFD symbol, measurement and / or reporting are performed based on the SBFD symbol or the non-SBFD symbol, wherein the second reference signal resource is any one of the one or more reference signal resources.

[0175] For example, for a CSI-RS resource used for RLM / BFD / CBD measurements, if some instances are on SBFD symbols and some instances are on non-SBFD symbols, the terminal only measures the instances of that resource appearing on symbols of the specific type. For instance, if the resource is predefined to be measured and / or reported based on SBFD symbols, the terminal only measures the instances of that resource appearing on SBFD symbols; or if the resource is predefined to be measured and / or reported based on non-SBFD symbols, the terminal only measures the instances of that resource appearing on non-SBFD symbols.

[0176] For example, for multiple CSI-RS resources used for RLM / BFD / CBD measurements, each resource may have some instances on SBFD symbols and some instances on non-SBFD symbols. The terminal will only measure the instances of these resources appearing on symbols of the specific type. For instance, if the predefined terminal measurement and / or reporting is based on SBFD symbols, the terminal will only measure the instances of these resources appearing on SBFD symbols; or if the predefined terminal measurement and / or reporting is based on non-SBFD symbols, the terminal will only measure the instances of these resources appearing on non-SBFD symbols.

[0177] For example, for three CSI-RS resources used for RLM / BFD / CBD measurements, if all instances of resource 1 are on SBFD symbols, all instances of resource 2 are on non-SBFD symbols, and some instances of resource 3 are on SBFD symbols and some are on non-SBFD symbols, then the terminal will only measure the instances of these resources appearing on symbols of specific types. For instance, if the terminal is predefined to perform measurements and / or reporting based on non-SBFD symbols, then the terminal will only measure the instances of resources 2 and 3 appearing on non-SBFD symbols.

[0178] In one possible implementation, the measurement of the reference signal is completed within a measurement time, which is determined based on the time interval and / or the number of instances of the second reference signal resource appearing on the SBFD symbol or the non-SBFD symbol. The calculation of this measurement time can be found in the foregoing description and will not be repeated here.

[0179] In one possible implementation, when the UE performs measurements on at least one CSI-RS resource on an SBFD symbol (the specific conditions are not limited, for example, all instances of the resource are on SBFD symbols, or some instances of the resource are on SBFD symbols and some instances are on non-SBFD symbols, and the network device is configured to report measurements for SBFD symbols, etc.), if at least one instance of the CSI-RS resource conflicts with dynamically scheduled uplink UL data transmission, the terminal does not transmit UL data but performs CSI-RS. Optionally, in this case, the measurement time does not consider the impact of conflicts with dynamically scheduled UL. That is, when determining the measurement time, both instances that do not conflict and instances that conflict are considered.

[0180] Furthermore, CSI-RS is determined to be performed without transmitting UL data on the SBFD symbol if one or more of the following conditions are met:

[0181] The one or more reference signal resources are used for Radio Link Monitoring (RLM) measurements and T310 timer is started; the one or more reference signal resources are used for RLM, Beam Failure Detection (BFD) or Alternate Beam Detection (CBD) measurements; the one or more reference signal resources are used for RLM, BFD or CBD measurements and the network device indicates not to transmit the UL data on the SBFD symbol; the one or more reference signal resources are used for neighbor cell measurements and the quality of the serving cell is lower than a first preset threshold and / or the quality of the neighbor cell is higher than a second preset threshold; the one or more reference signal resources are used for neighbor cell measurements and the UL service does not include signaling transmission or preset priority data (such as high priority data); the one or more reference signal resources are used for neighbor cell measurements and the network device indicates not to transmit the UL data on the SBFD symbol; the one or more reference signal resources are used for beam measurements and when the transmission configuration indicates TCI switching or path-loss reference signal switching.

[0182] In other words, when a conflict occurs, the UE will not send UL data but will perform CSI-RS measurements if the above conditions are met.

[0183] In one possible implementation, when the aforementioned conflict occurs, the measurement time is determined based on the time interval and / or the number of instances of the resource appearing on the SBFD symbol. For a description of this part, please refer to the foregoing records, which will not be repeated here.

[0184] In one possible implementation, when measuring the one or more reference signal resources on the SBFD symbol, if at least one instance of the CSI-RS resource conflicts with a dynamically scheduled UL transmission, for example, if the aforementioned condition is not met, UL data is transmitted on the SBFD symbol without performing CSI-RS measurement. Optionally, the measurement of the reference signal is completed within a measurement time, wherein the measurement time is extended according to the number of instances where the one or more reference signal resources conflict with the dynamically scheduled UL. The calculation of this measurement time can be found in the foregoing description and will not be repeated here.

[0185] In this embodiment, the terminal measures the reference signal based on configuration information and predefined rules, enabling the terminal to perform measurements and / or report based on SBFD symbols or non-SBFD symbols. This eliminates the possibility of cross-symbol type filtering during the measurement process, ensuring the accuracy of the measurement and the consistency of SINR / RSRP at different points during the filtering process.

[0186] Referring to Figure 6, a flowchart illustrating another communication method provided in an embodiment of this application is shown. Optionally, this method can be applied to the aforementioned communication system, such as the communication system shown in Figure 1a. The communication method shown in Figure 6 may include steps 601-602, as follows:

[0187] 601. The network device sends configuration information to the terminal, which is used to configure one or more reference signal resources. Accordingly, the terminal receives the configuration information.

[0188] 602. The terminal measures the reference signal based on the configuration information. Specifically, when measuring one or more reference signal resources on an SBFD symbol, if one or more of the following conditions are met, it is determined that uplink UL data will not be transmitted on that SBFD symbol:

[0189] The one or more reference signal resources are used for Radio Link Monitoring (RLM) measurements and T310 timer is started; the one or more reference signal resources are used for RLM, Beam Failure Detection (BFD) or Alternate Beam Detection (CBD) measurements; the one or more reference signal resources are used for RLM, BFD or CBD measurements and the network device indicates not to transmit the UL data on the SBFD symbol; the one or more reference signal resources are used for neighbor cell measurements and the quality of the serving cell is lower than a first preset threshold and / or the quality of the neighbor cell is higher than a second preset threshold; the one or more reference signal resources are used for neighbor cell measurements and the UL service does not include signaling transmission or preset priority data; the one or more reference signal resources are used for neighbor cell measurements and the network device indicates not to transmit the UL data on the SBFD symbol; the one or more reference signal resources are used for beam measurements and during TCI handover or path-loss reference signal handover.

[0190] In one possible implementation, the terminal completes the measurement of the reference signal within a measurement time, which is determined based on the time interval and / or the number of instances of the one or more reference signal resources appearing on the SBFD symbol. The calculation of this measurement time can be found in the foregoing description and will not be repeated here.

[0191] In one possible implementation, the configuration information also indicates one or more of the following: not transmitting UL data on the SBFD symbol, the first preset threshold corresponding to the quality of the serving cell, and / or the second preset threshold corresponding to the quality of the neighboring cell.

[0192] In one possible implementation, when measuring the one or more reference signal resources on the SBFD symbol, the measurement of the reference signal is completed within a measurement time while transmitting UL data on the SBFD symbol, wherein the measurement time is extended according to the number of instances where the one or more reference signal resources conflict with dynamically scheduled ULs. The calculation of this measurement time can be found in the foregoing description and will not be repeated here.

[0193] In this embodiment of the application, when the terminal performs measurement and dynamic scheduling of UL conflicts, prioritizing measurement helps the terminal to judge the link quality more promptly, avoids unnecessary triggering of link failure or beam failure, ensures that the terminal can obtain measurement results in a timely manner when it is at the cell edge, and ensures that important processes are completed in a timely manner.

[0194] It should be noted that, in the various embodiments of this application, unless otherwise specified or in case of logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0195] The methods of the embodiments of this application have been described in detail above, and the apparatus of the embodiments of this application is provided below. It is understood that the division of multiple units or modules in the various apparatus embodiments of this application is only a logical division based on function and is not intended to limit the specific structure of the apparatus. In specific implementations, some functional modules may be subdivided into more smaller functional modules, and some functional modules may be combined into a single functional module. However, regardless of whether these functional modules are subdivided or combined, the general flow executed by the apparatus is the same. For example, some apparatuses include a receiving unit and a transmitting unit. In some designs, the transmitting unit and the receiving unit can also be integrated into a communication unit, which can implement the functions implemented by the receiving unit and the transmitting unit. Typically, each unit corresponds to its own program code (or program instructions). When the program code corresponding to each unit runs on the processor, it causes the unit to be controlled by the processing unit to execute the corresponding flow and thus achieve the corresponding function.

[0196] This application also provides an apparatus for implementing any of the above methods. For example, a communication apparatus is provided that includes a module (or means) for implementing the steps performed by the terminal in any of the above methods.

[0197] For example, referring to FIG7, which is a schematic diagram of a communication device provided in an embodiment of this application, the communication device is used to implement the aforementioned communication method, such as the communication method shown in FIG3, FIG5 or FIG6.

[0198] As shown in Figure 7, the device may include a communication module 701 and a processing module 702, as detailed below:

[0199] When the communication device is used to implement the functions of the terminal: the communication module 701 is used to implement one or more operations implemented by the terminal in step 301 of the embodiment shown in FIG3, or to implement one or more operations implemented by the terminal in step 501 of the embodiment shown in FIG5, or to implement one or more operations implemented by the terminal in step 601 of the embodiment shown in FIG6.

[0200] The processing module 702 is used to implement one or more operations implemented by the terminal in step 302 of the embodiment shown in FIG3, or to implement one or more operations implemented by the terminal in step 502 of the embodiment shown in FIG5, or to implement one or more operations implemented by the terminal in step 602 of the embodiment shown in FIG6.

[0201] The above modules can be described in the description of the foregoing embodiments, and will not be repeated here.

[0202] For example, referring to Figure 8, which is a schematic diagram of another communication device provided in an embodiment of this application. This communication device is used to implement the aforementioned communication method, such as the communication method shown in Figure 3, Figure 5, or Figure 6.

[0203] As shown in Figure 8, the device may include a communication module 801, specifically as follows: when the communication device is used to implement the functions of a network device: the communication module 801 is used to implement one or more operations implemented by the network device in step 301 of the embodiment shown in Figure 3, or to implement one or more operations implemented by the network device in step 501 of the embodiment shown in Figure 5, or to implement one or more operations implemented by the network device in step 601 of the embodiment shown in Figure 6.

[0204] The above modules can be described in the description of the foregoing embodiments, and will not be repeated here.

[0205] In one possible implementation, the above communication method is applied to an O-RAN architecture, and the implementation of the communication module can be executed in the CU, DU, and RU. Execution in the CU can specifically be performed in the CU-CP. The CU-CP is a logical node carrying the RRC layer and PDCP-C layer, used to implement the CU's control plane functions. In this scheme, the implementation of the communication module can be performed by the CU-CP, for example, generating RRC signaling for configuring RLM / BFD / CBD measurements. The DU is a logical node carrying the Radio Link Control (RLC) layer, MAC layer, Higher PHY, and other functions. In this scheme, the DU can perform RLC, MAC, and Higher PHY layer processing on the RRC signaling generated in the CU-CP. The RU is a logical node carrying Lower PHY and RF processing. In this scheme, the RU can further process the RRC signaling generated in the CU-CP using Lower PHY and RF processing, and then send the RRC signaling to the UE via the air interface.

Execution in the CU can specifically be performed in the CU-CP. The CU-CP is a logical node carrying the RRC layer and PDCP-C layer, used to implement the CU's control plane functions. In this scheme, the implementation of the communication module can be performed by the CU-CP, for example, generating RRC signaling for configuring RLM / BFD / CBD measurements. The DU is a logical node carrying the Radio Link Control (RLC) layer, MAC layer, Higher PHY, and other functions. In this scheme, the DU can perform RLC, MAC, and Higher PHY layer processing on the RRC signaling generated in the CU-CP. The RU is a logical node carrying Lower PHY and RF processing. In this scheme, the RU can further process the RRC signaling generated in the CU-CP using Lower PHY and RF processing, and then send the RRC signaling to the UE via the air interface.

[0217] In this embodiment, the memory (e.g., memory 903, memory 904, memory 905) may include, but is not limited to, cache, read-only memory (ROM), random access memory (RAM), synchronous dynamic random access memory (SDRAM), hard disk drive (HDD) or solid-state drive (SSD), erasable programmable read-only memory (EPROM), or compact disc read-only memory (CD-ROM), etc. Memory is any other medium capable of carrying or storing desired program code having an instruction or data structure form and accessible by a computer, but is not limited thereto.
