Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and particularly relates to a communication method and device, a storage medium and a program product. BACKGROUND

[0002] In the conclusions of the 117th meeting of the first working group of the 3rd generation partnership project (3GPP) wireless access network (RAN1#117), it is supported to report respectively for two types of symbols (subband full duplex (SBFD) symbols and non-SBFD symbols) in channel state information (CSI) measurement, for example, to indicate the reporting configuration for each type of symbol respectively, and it is also considered that the channel state indicator-reference signal (CSI-RS) resources of some instances on SBFD symbols and some instances on non-SBFD symbols are configured by the network to indicate the terminal to receive on which type of symbol. If there are at least one downlink (DL) subband and at least one uplink (UL) subband in a time domain symbol, the symbol is called an SBFD symbol. If all symbols in a slot are SBFD symbols, the slot is called an SBFD slot. In the SBFD scheme, a carrier is divided into multiple subbands, and the transmission directions of different subbands can be different. However, the prior art does not clearly indicate how the CSI-RS resources perform other types of measurements in the SBFD scenario. SUMMARY

[0003] The present application discloses a communication method, device, storage medium and program product, which can improve the accuracy of measurement.

[0004] In a first aspect, an embodiment of the present application provides a communication method. The method can be applied to a terminal side, for example, a terminal or a communication module / processing module in the terminal, or a circuit or chip responsible for communication function in the terminal (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core, or a circuit or chip responsible for processing function in the terminal (such as a graphics processing unit (GPU)). Taking the case where the method is applied to a terminal, in the method, the terminal receives configuration information from a network device, the configuration information being used to configure one or more reference signal resources, the configuration information including configuration information of a first reference signal resource, wherein the first reference signal resource corresponds to an instance on a sub-band full duplex (SBFD) symbol or a 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 that measurement and / or reporting are based on the SBFD symbol or the non-SBFD symbol. Then, the terminal measures a reference signal based on the configuration information.

[0005] In an embodiment of the present application, the terminal measures a reference signal based on the configuration information sent by the network device, so that the terminal determines the type of symbol for measurement, eliminates the possibility of cross-symbol type filtering in the measurement process, and ensures the accuracy of the measurement and the consistency of the signal to interference plus noise ratio (SINR) / reference signal received power (RSRP) at different sample points in the filtering process.

[0006] In a possible implementation, each of the one or more reference signal resources corresponds to an instance on the SBFD symbol or the non-SBFD symbol.

[0007] Alternatively, some of the one or more reference signal resources correspond to instances on the SBFD symbol, and the other part of the resources correspond to instances on the non-SBFD symbol, and the like.

[0008] In a possible implementation, according to the configuration information, when a first part of an instance corresponding to a second reference signal resource appears on the SBFD symbol and a second part appears on the non-SBFD symbol, measurement and / or reporting are performed based on the SBFD symbol or the non-SBFD symbol, where the second reference signal resource is any one of the one or more reference signal resources. In this way, the accuracy of measurement and the consistency of SINR / RSRP at different sample points in the filtering process are ensured.

[0009] In a possible implementation, the measurement of the reference signal is completed within a measurement time, and the measurement time is determined based on a time interval and / or a number of instances in which the second reference signal resource appears on the SBFD symbol or the non-SBFD symbol.

[0010] In a possible implementation, when the one or more reference signal resources are measured on the SBFD symbol, if one or more of the following conditions is met, it is determined that no uplink (UL) data is transmitted on the SBFD symbol.

[0011] The one or more reference signal resources are used for radio link monitoring (RLM) measurement and a T310 timer is started, the one or more reference signal resources are used for RLM, beam failure detection (BFD), or candidate beam detection (CBD) measurement, the one or more reference signal resources are used for RLM, BFD, or CBD measurement and the network device indicates that no UL data is transmitted on the SBFD symbol, the one or more reference signal resources are used for neighbor cell measurement and the quality of a serving cell is lower than a first preset threshold and / or the quality of a neighbor cell is higher than a second preset threshold, the one or more reference signal resources are used for neighbor cell measurement and the UL traffic does not include signaling transmission or preset priority data, the one or more reference signal resources are used for neighbor cell measurement and the network device indicates that no UL data is transmitted on the SBFD symbol, and the one or more reference signal resources are used for beam measurement and when a transmission configuration indicator (TCI) is switched or a path-loss reference signal is switched.

[0012] In this way, unnecessary triggering of link failure or beam failure caused by untimely measurement is avoided. Alternatively, the terminal is facilitated to obtain measurement results in time when at the cell edge. Alternatively, the impact of measurement on important UL traffic is avoided, and measurement is prioritized when the UL traffic priority is low to ensure timely mobility measurement. Alternatively, important procedures such as TCI switching or path-loss reference signal switching are ensured to be completed in time.

[0013] In a possible implementation, when the one or more reference signal resources conflict with dynamically scheduled UL in the SBFD symbol, the reference signal is measured within a measurement time, which is determined based on a time interval and / or a number of instances in which the one or more reference signal resources appear on the SBFD symbol.

[0014] In a possible implementation, the configuration information further indicates one or more of the following: no UL data is transmitted 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 neighbor cell.

[0015] In a possible implementation, when the one or more reference signal resources conflict with dynamically scheduled UL in the SBFD symbol, the reference signal is measured within a measurement time, which is extended according to a number of instances in which the one or more reference signal resources conflict with dynamically scheduled UL.

[0016] In a possible implementation, the configuration information further indicates time domain and / or frequency domain configuration of the SBFD symbol of the neighbor cell that transmits 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 neighbor cell is the same as that of the serving cell.

[0017] In this way, the terminal correctly measures the reference signal resources transmitted by the neighbor cell by using the time and frequency domain configuration information of the SBFD of the neighbor cell.

[0018] In a second aspect, an embodiment of the present application provides a communication method. The method can be applied to a terminal side, for example, a terminal or a communication module / processing module in the terminal, or a circuit or chip responsible for communication functions in the terminal (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or system in package (SIP) chip containing a modem core), or a circuit or chip responsible for processing functions in the terminal (such as a graphics processing unit (GPU)). Taking the case where the method is applied to a terminal, in the method, the terminal receives configuration information from a network device, the configuration information being used to configure one or more reference signal resources. Further, the terminal measures a reference signal based on the configuration information and a predefined rule, the predefined rule including: measuring and / or reporting based on SBFD symbols or non-SBFD symbols.

[0019] In an embodiment of the present application, the terminal measures a reference signal based on configuration information and a predefined rule, so that the terminal measures and / or reports based on SBFD symbols or non-SBFD symbols, which eliminates the possibility of cross-symbol type filtering in the measurement process and ensures the accuracy of the measurement and the consistency of SINR / RSRP on different samples in the filtering process.

[0020] Some possible implementations and benefits of the second aspect can be referred to the above-mentioned first aspect, and will not be described here.

[0021] In a possible implementation, according to the predefined rule, when a first part of an instance corresponding to a second reference signal resource appears on the SBFD symbol and a second part appears on the non-SBFD symbol, the measurement and / or reporting are based on the SBFD symbol or the non-SBFD symbol, where the second reference signal resource is any one of the one or more reference signal resources.

[0022] In a third aspect, an embodiment of the present application provides a communication method. The method can be applied to a network side, for example, an access network device on the network side, a module (such as a circuit, a chip or a chip system, etc.) in the access network device, or a logic node, a logic module or software capable of realizing all or part of the functions of the access network device. Taking the case where the method is applied to an access network device, in the method, the access network device sends configuration information, the configuration information being used to configure one or more reference signal resources, the configuration information including configuration information of a first reference signal resource, where an 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 that the measurement and / or reporting are based on the SBFD symbol or the non-SBFD symbol.

[0023] In this example, the measurement of the reference signal based on the configuration information sent by the network device can eliminate the possibility of cross-symbol type filtering in the measurement process, and ensure the accuracy of the measurement and the consistency of SINR / RSRP on different sample points in the filtering process.

The communication device 120 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, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, unmanned aerial vehicle, robot, remote sensing, passive sensing, positioning, navigation and tracking, autonomous delivery and mobile, etc.Some examples of the communication device 120 are: a user equipment (UE) of the third generation partnership project (3GPP) standard, a fixed device, a mobile device, a handheld device, a wearable device, a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a notebook, a personal computer, a smart book, a vehicle, a satellite, a global positioning system (GPS) device, a drone, a helicopter, an aircraft, a ship, a remote control device, a smart home device, an industrial device, a personal communication service (PCS) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a wireless webcam, a tablet, a palm computer, a mobile internet device (MID), a wearable device such as a smart watch, a smart point of sale (POS) machine, a customer-premises equipment (CPE), a light UE, a reduced capability UE (REDCAP UE), a wireless terminal in industrial control, a terminal in Internet of Things (IoT) system, a wireless terminal in self driving, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city such as a smart fuel dispenser, a terminal on a high-speed train, and a wireless terminal in a smart home such as a smart speaker, a smart coffee machine, a smart printer, etc. The communication device 120 can be a wireless device in the above various scenarios or an apparatus used in the wireless device, e.g., a communication module, a modem, or a chip in the above devices. The communication device can also be a vehicle apparatus, e.g., a whole vehicle apparatus, a vehicle-mounted module, a vehicle-mounted chip, an on board unit (OBU), or a telematics box (T-BOX), etc. The communication device can also be referred to as a terminal, a terminal device, a UE, a mobile station (MS), a mobile terminal (MT), etc. The communication device can also be a communication device in a future wireless communication system. The communication device can be used in a dedicated network device or a general-purpose device. The embodiments of the present application do not limit specific technologies and specific device forms adopted by the communication device.

[0077] Exemplarily, the communication device can be used to act as a base station. For example, the UE can act as a scheduling entity which provides sidelink signals between UEs in V2X, D2D or P2P, etc. As shown in the figure, the cellular phone 120a and the car 120b communicate with each other by using sidelink signals. The cellular phone 120a and the smart home device 120e communicate without relaying the communication signals through the base station 110b. Figure 1a

[0078] In the present application, the communication device for realizing the function of the communication device can be a terminal, or a terminal with part of the function of the above communication device, or a device capable of supporting the realization of the function of the above communication device, such as a chip system, which can be installed in or matched with the terminal. In the present application, the chip system can be composed of a chip, or include a chip and other discrete devices. In the technical solutions provided in the present application, the communication device is exemplarily taken as a terminal or UE for description.

[0079] Exemplarily, a wireless communication system is usually composed of a cell, and a base station provides management of the cell and provides communication services to a plurality of MSs in the cell. The base station includes a BBU and a RRU. The BBU and the RRU can be placed in different places, for example, the RRU is pulled away and placed in a high traffic area, and the BBU is placed in a central machine room. The BBU and the RRU can also be placed in the same machine room. The BBU and the RRU can also be different components under one rack. Exemplarily, one cell can correspond to one carrier or a member carrier.

[0080] It can be understood that the present application can be applied between a network device and a communication device, between network devices, or between communication devices, i.e., between a primary device and a secondary device. 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.

[0081] ​The communication between the access network device and the terminal follows a certain protocol layer structure. The 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 a radio resource control (RRC) layer, a PDCP layer, a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical layer. For example, the user plane protocol layer structure can include the functions of protocol layers such as a PDCP layer, an RLC layer, a MAC layer, and a physical layer, and in one possible implementation, a service data adaptation protocol (SDAP) layer can be further included above the PDCP layer.

[0082] Exemplarily, the protocol layer structure between the access network device and the terminal can further include an artificial intelligence (AI) layer for transmitting data related to AI functions.

[0083] Taking the data transmission between the access network device and the terminal as an example, the data transmission needs to pass through the user plane protocol layers, such as the SDAP layer, the PDCP layer, the RLC layer, the MAC layer, and the physical layer. Among them, the SDAP layer, the PDCP layer, the RLC layer, the MAC layer, and the physical layer can also be collectively referred to as an access layer. According to the transmission direction of the data, each layer is divided into a sending part and a receiving part. Taking the following downlink data transmission as an example, the PDCP layer obtains data from the upper layer, transmits the data to the RLC layer and the MAC layer, generates a transport block by the MAC layer, and then performs wireless transmission through the physical layer. The data is encapsulated in each layer. For example, the data received by a layer from the upper layer of the layer is regarded as the SDU of the layer, and after encapsulation by the layer, it becomes a PDU, and is then transmitted to the next layer.

[0084] Exemplarily, the terminal can also have an application layer and a non-access layer. Among them, the application layer can be used to provide services to the application programs installed in the terminal, such as, the downlink data received by the terminal can be transmitted by the physical layer to the application layer in turn, and then provided to the application programs by the application layer; for example, the application layer can obtain the data generated by the application programs, and transmit the data to the physical layer in turn, and send to other communication devices. The non-access layer can be used to forward user data, such as forwarding the uplink data received from the application layer to the SDAP layer or forwarding the downlink data received from the SDAP layer to the application layer.

[0085] The access network device can include a CU and a DU. A plurality of DUs can be centrally controlled by one CU. As an example, the interface between the CU and the DU can be referred to as an F1 interface. Among them, the control panel (CP) interface can be F1-C, and the user panel (UP) interface can be F1-U. The CU and the DU can be divided according to the protocol layer of the wireless network: for example, the functions of the PDCP layer and above protocol layers are arranged in the CU, and the functions of the protocol layers below the PDCP layer (such as the RLC layer and the MAC layer, etc.) are arranged in the DU; for another example, the functions of the protocol layers above the PDCP layer are arranged in the CU, and the functions of the protocol layers at and below the PDCP layer are arranged in the DU.

[0086] It can be understood that the above-mentioned processing functions of the CU and the DU according to the division of the protocol layer are only an example, and can also be divided in other ways, for example, the CU or the DU can be divided into functions with more protocol layers, and for another example, the CU or the DU can also be divided into partial processing functions with protocol layers. In one design, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are arranged in the DU. In another design, the functions of the CU or the DU can also be divided according to the service type or other system requirements, for example, according to the delay, the functions that need to meet the delay requirement of the processing time are arranged in the DU, and the functions that do not need to meet the delay requirement are arranged in the CU. In another design, the CU can also have one or more functions of the core network. For example, the CU can be arranged at the network side for centralized management. In another design, the RU of the DU is remotely arranged. Among them, the RU has a radio frequency function.

[0087] Exemplarily, the DU and the RU can be divided at a physical layer (PHY). For example, the DU can implement high-layer functions in the PHY, and the RU can implement low-layer functions in the PHY. Wherein, for transmission, the functions of the PHY can include adding a cyclic redundancy check (CRC) code, channel coding, rate matching, scrambling, modulation, layer mapping, precoding, resource mapping, physical antenna mapping, and / or radio frequency transmission functions. For reception, the functions of the PHY can include CRC, channel decoding, de-rate matching, descrambling, demodulation, de-layer mapping, channel detection, resource demapping, physical antenna demapping, and / or radio frequency reception functions. Wherein, the high-layer functions in the PHY can include part of the functions of the PHY, for example, the part of the functions is closer to the MAC layer, and the low-layer functions in the PHY can include another part of the functions of the PHY, for example, the part of the functions is closer to the radio frequency functions. For example, the high-layer functions in the PHY can include adding a CRC code, channel coding, rate matching, scrambling, modulation, and layer mapping, and the low-layer functions in the PHY can include precoding, resource mapping, physical antenna mapping, and radio frequency transmission functions; or the high-layer functions in the PHY can include adding a CRC code, channel coding, rate matching, scrambling, modulation, layer mapping, and precoding, and the low-layer functions in the PHY can include resource mapping, physical antenna mapping, and radio frequency transmission functions.

[0088] Exemplarily, the functions of the CU can be implemented by one entity, or can also be implemented by different entities. For example, the functions of the CU can be further divided, that is, the control plane and the user plane are separated and implemented by different entities, respectively, as a control plane CU entity (that is, a CU-CP entity) and a user plane CU entity (that is, a CU-UP entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the functions of the access network device.

[0089] In the above architecture, the signaling generated by the CU can be transmitted to the terminal through the DU, or the signaling generated by the terminal can be transmitted to the CU through the DU. For example, the signaling of the RRC or the PDCP layer is finally processed as the signaling of the physical layer to be transmitted to the terminal, or is converted from the received physical layer signaling. In this architecture, the signaling of the RRC or the PDCP layer can be considered as being transmitted through the DU, or being transmitted through the DU and the RU.

[0090] Exemplarily, any of the above DU, CU, CU-CP, CU-UP and RU can be a software module, a hardware structure, or a software module + hardware structure, without limitation. Among them, the existence forms of different entities can be different, without limitation. For example, the DU, CU, CU-CP, CU-UP are software modules, and the RU is a hardware structure. These modules and the methods they perform are also within the protection scope of the present application.

[0091] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the O-RAN system, the CU can also be referred to as O-CU (open CU), the DU can also be referred to as O-DU, the CU-CP can also be referred to as O-CU-CP, the CU-UP can also be referred to as O-CU-UP, and the RU can also be referred to as O-RU.

[0092] It should be understood that Figure 1a The number and type of devices in the illustrated communication system are only illustrative, and the present application is not limited thereto. In actual applications, more terminals and more access network devices can also be included in the communication system, and other network elements can also be included, for example, core network devices and / or network elements for implementing artificial intelligence functions can be included.

[0093] It can be understood that all or part of the functions implemented by one or more of the terminal, the access network device, the core network device, or the network element for implementing artificial intelligence functions can be virtualized, that is, implemented by one or more of a special processor or a general processor and a corresponding software module. Among them, the terminal and the access network device involve the interface of air interface transmission, and the transceiving function of the interface can be realized by hardware. The core network device, such as the operation administration and maintenance (OAM) network element, can be virtualized. Exemplarily, one or more functions of the virtualized terminal, access network device, core network device, or network element for implementing artificial intelligence functions can be implemented by a cloud device, such as a cloud device in an over the top (OTT) system.

[0094] The method provided by the present application can be used for communication between the access network device and the terminal, and can also be used for communication between other communication devices, such as communication between a macro base station and a micro base station in a wireless backhaul link, and communication between two terminals in a sidelink (SL), etc., without limitation.

[0095] In this application, "sending information to (for example, a terminal)" or related illustrations in the drawings can be understood as the destination of the information is the terminal. It can include direct or indirect sending information to the terminal. "Receiving information from (for example, a terminal)" or "receiving information from (for example, a terminal)", or related illustrations in the drawings can be understood as the source of the information is the terminal, which can include direct or indirect receiving information from the terminal. The information between the source and the destination of the information transmission can be processed as necessary, such as format change, etc., but the destination can understand the effective information from the source. Similar expressions in this application can be similarly understood, and will not be repeated here.

[0096] As shown in Figure 1b , an example diagram of an O-RAN system is shown in this application, which can include other components in addition to the components shown in Figure 1b . As shown in Figure 1b , the access network device (RAN, which can be eNB or gNB or next generation access network device) communicates with the core network (CN) through the backhaul link, and communicates with the user equipment UE through the air interface.

[0097] For example, the baseband unit (BBU) in the access network device communicates with the core network through the backhaul link, and the radio frequency unit (RU) in the access network device communicates with at least one UE through the air interface. The BBU communicates with at least one RU through the fronthaul link, and the BBU and the RU can be co-located or not.

[0098] The BBU includes at least one control unit (CU) and at least one distributed unit (DU), which can communicate through at least one midhaul link.

[0099] As shown in Figure 1cAs shown, a figure of network element function division and protocol layer structure of an O-RAN device is shown in this application. In some examples, the CU is a logical node that carries the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer and other control functions of the access network device. The CU is connected to network nodes such as core network through some interfaces, which can be E2 interface and the like. Optionally, the CU can have part of the function of the core network. The CU (such as the PDCP layer and higher layers) is connected to the DU (such as the RLC layer and lower layers) through some interfaces, which can be F1 interface and the like. In some examples, these interfaces (such as F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (such as interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of F1 interface, which defines the signaling process of F1 in some examples. The F1 interface supports the control plane F1-C and the user plane F1-U.

[0100] In some examples, the CU can be split into a control unit-control plane (CU-CP) and a control unit-user plane (CU-UP), where the CU-CP is a logical node carrying the RRC layer and the control plane part of PDCP (PDCP-C) layer, used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function can be an access and mobility function network element, such as an access and mobility management function (AMF) in a 5G system. The AMF network element is used to be responsible for mobility management in a mobile network, such as location update of a terminal device, registration network of the terminal device, handover of the terminal device, etc. The CU-UP is a logical node carrying the SDAP layer and the user plane part of PDCP (PDCP-U) layer, used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, a UPF in a 5G system, is used to be responsible for forwarding and receiving data in a terminal device. The above configuration of the CU and the DU is only an example, and the CU and the DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, for example, according to the delay. The functions that need to meet the delay requirement are arranged in the DU, and the functions that do not need to meet the delay requirement are arranged in the CU.

[0101] In some examples, a DU is a logical node that hosts radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU is connected with the RUs through some interfaces, which can be a fronthaul interface. In some examples, the higher PHY layer includes parts of PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and other processing functions.

[0102] In some examples, an RU is a logical node that hosts lower physical layer (lower PHY) and radio frequency (RF) processing. In some examples, an RU can be a 3GPP transmission reception point (TRP) or a remote radio head (RRH) or other similar functional entity. In some examples, the lower PHY includes parts of PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, and other processing functions. The RU communicates with one or more UEs over a wireless link.

[0103] The DU and the RU can be co-located or not co-located. The DU and the RU exchange control plane information and user plane information via a lower layer split-CUS-plane (LLS-CUS) interface through a fronthaul link. The LLS-CUS can include a LLS-C interface and a LLS-U interface that provide control plane (C-plane) and user plane (U-plane), respectively. In some examples, the control plane (C-plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a LLS-M interface of the fronthaul link, and the management plane (M-plane) refers to non-real-time management operations between the DU and the RU.

[0104] 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.

[0105] like Figure 1d The diagram illustrates an example of a baseband hardware implementation, which can be implemented using a processing system comprising 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 processors used in the baseband can be used to implement the processes described below and any one or more of those processes.

[0106] 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.

[0107] 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.

[0108] The processor is responsible for managing the bus and general processing, including the execution of software stored on the computer-readable medium. The software, when executed by the processor, causes the processing system to perform the various functions described below for any particular apparatus.

[0109] The functions that the processor and memory and computer-readable medium can implement can be encoding, decoding, rate matching, de-rate matching, scrambling, descrambling, modulation, demodulation, layer mapping, FFT, IFFT, inverse discrete fourier transform (IDFT), precoding, resource element (RE) mapping, channel equalization, de-RE mapping, digital beamforming (BF), adding cyclic prefix (CP), de-CP, and the like.

[0110] As shown in Figure 1e A common architecture of RAN chips is shown in this application, which is 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 and between the CU and core network. The DU performs L1 and part of L2 functions, and the RU performs L1 computation and RF digital part functions; the fronthaul and backhaul interfaces are used to carry traffic between the RU and DU and between the CU and DU. The integrated DU includes the above-mentioned DU and RU functions.

[0111] The CU / DU hardware includes a chassis platform, a mainboard, peripherals, and cooling equipment. The mainboard contains processing units, memory, internal I / O interfaces, and external connection ports. Its hardware accelerator design has an interface, and the hardware function components include: storage of software, hardware, and system debugging interfaces, and a single-board management controller.

[0112] The DU system is usually implemented using a multi-core processor and one or more hardware accelerators. Part of the DU protocol stack can be implemented in software running on the multi-core processor, and the computationally intensive L1 and L2 functions can be offloaded to FPGA / GPU-based hardware accelerators; or all L1 functions are offloaded to FPGA / GPU-based hardware accelerators, while other protocol stack contents are implemented in software running on the processor; or all protocol stacks are implemented in software running on the processor. The hardware accelerator supports interconnection with an x86 or non-x86 processor, and for the same reason, the accelerator has a multi-channel PCIe interface pointing to the CPU and is externally connected through GbE connection.

[0113] The RU includes three parts: an O-RAN processing unit (OPU) receives eCPRI frames from the O-RAN fronthaul and performs the fronthaul interface, the lowest layer 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 digital processing unit (DPU) of the O-RU performs synchronization, digital downconverter (DDC) in the UL, digital upconverter (DUC) in the downlink (DL), CFR, and DPD to improve power amplifier efficiency by reducing the PAPR / ACLR of the RF front end; the DPU can be implemented as an FPGA or an application-specific integrated circuit (ASIC). The RF processing unit of the O-RU includes a transceiver module, up / down converter, power amplifier (PA), low noise amplifier (LNA), Tx / Rx filter. All conversions between the analog and digital domains (DAC and ADC) (for example, (RF sampling, using RF in upconversion and downconversion, intermediate frequency (IF), and local oscillator (LO) mixing for frequency conversion) are performed within the transceiver module. Note that the physical and logical partitions within the RF processing unit do not require specific boundaries.

[0114] The professional terms related to the present application are introduced as follows.

[0115] 1、SBFD

[0116] The 5G New Radio (NR) wireless communication system is deployed in the medium and high frequency bands, and high data rate and low latency are achieved by using a large bandwidth. In the existing Time Division Duplexing (TDD) system, the downlink (DL) usually occupies the main time resource, which causes an imbalance in the coverage between the DL and the uplink (UL). Compared with the Frequency Division Duplexing (FDD) system, the uplink coverage of the TDD system is poorer and the latency is larger. In view of the problems of uplink coverage and latency in the TDD system, the 3GPP proposes a sub-band full duplex (SBFD) scheme. In the SBFD scheme, one carrier is divided into multiple sub-bands, and the transmission direction of different sub-bands can be different. A typical SBFD scheme is shown in FIG. 1, in which one carrier is divided into three sub-bands, and the middle sub-band is the uplink, and the upper and lower sub-bands are the downlink. Figure 2 The 5G New Radio (NR) wireless communication system is deployed in the medium and high frequency bands, and high data rate and low latency are achieved by using a large bandwidth. In the existing Time Division Duplexing (TDD) system, the downlink (DL) usually occupies the main time resource, which causes an imbalance in the coverage between the DL and the uplink (UL). Compared with the Frequency Division Duplexing (FDD) system, the uplink coverage of the TDD system is poorer and the latency is larger. In view of the problems of uplink coverage and latency in the TDD system, the 3GPP proposes a sub-band full duplex (SBFD) scheme. In the SBFD scheme, one carrier is divided into multiple sub-bands, and the transmission direction of different sub-bands can be different. A typical SBFD scheme is shown in FIG. 1, in which one carrier is divided into three sub-bands, and the middle sub-band is the uplink, and the upper and lower sub-bands are the downlink.

[0117] In the SBFD scheme, on the SBFD symbol, the base station can achieve simultaneous transmission and reception through different frequency domain resources (subbands). Currently, in the R19 standard discussion, it is decided to adopt the technical route of "network device side subband full duplex, terminal device side half duplex", the network device side subband full duplex means that the network device can simultaneously transmit on the downlink subband and receive on the uplink subband on the SBFD symbol, and the terminal device half duplex means that the terminal device can only receive on the downlink subband or transmit on the uplink subband on the SBFD symbol, and cannot simultaneously receive or transmit. Under the SBFD scheme, the available uplink transmission resources of the terminal device are increased, which can effectively improve the uplink coverage and reduce the uplink delay.

[0118] If there is at least one DL subband and at least one UL subband on a time domain symbol, the symbol is called an SBFD symbol. If all symbols in a slot are SBFD symbols, the slot is called an SBFD slot. Figure 2 The TDD configuration of five consecutive slots is DDDSU, wherein the second and third DL slots are configured as SBFD slots.

[0119] 2. Radio link monitoring (RLM) / beam failure detection (BFD) / candidate beam detection (CBD) measurement

[0120] RLM measurement is a measurement performed by the terminal on the reference signal specified by the network to monitor the quality of the wireless link, and the received performance of the physical downlink control channel (PDCCH) under the current link quality is judged through the measurement result. If the received performance (measured by block error ratio (BLER)) is lower than a certain threshold, the terminal will record an out-of-sync (OOS). When the number of OOS exceeds a certain threshold, the terminal starts the T310 timer. When the T310 timer expires, it will trigger RRC reestablishment. If the received performance of the PDCCH under the current link quality is higher than a certain threshold, the terminal will record an in-sync (IS). If the number of IS exceeds a certain threshold before T310 expires, the terminal considers that the link is recovered.

[0121] BFD measurement is similar to RLM measurement, which is a measurement performed by the terminal on the reference signal specified by the network to monitor the quality of the current serving beam, and the received performance of the physical downlink control channel (PDCCH) under the current beam quality is judged through the measurement result. If the received performance (measured by block error ratio (BLER)) is lower than a certain threshold, the terminal will record an out-of-sync (OOS). When the number of OOS exceeds a certain threshold within a certain time length, beam failure will be triggered, and then CBD measurement will be triggered.

[0122] CBD measurement is the process that the terminal finds a new available beam by measuring the reference signal designated by the network after the beam failure is triggered. When the terminal finds the Layer 1-Reference Signal Received Power (L1-RSRP) on a reference signal is higher than a certain threshold through measurement, the found reference signal is informed to the network through random access channel (RACH) or other processes.

[0123] 3. L3 mobility measurement

[0124] In NR, the terminal can perform mobility measurement on the CSI-RS resource sent by the neighbor cell. The terminal reports the measurement result to the network through L3 signaling, and the network usually uses the measurement result to make mobility (such as cell handover) decision. The serving cell indicates the cell where the to-be-measured CSI-RS resource is located, the frequency domain position (bandwidth and starting resource block (RB)), the time domain position (periodicity and offset), and the associated synchronization signal and physical broadcast channel (physical broadcast channel, PBCH) block (synchronization signal and PBCH block, SSB) and other information in the measurement configuration. The time domain position is configured relative to the timing of the neighbor cell. If the associated SSB is configured, the terminal needs to detect the associated SSB before measuring a certain CSI-RS resource, and only in the case of detecting the associated SSB, the CSI-RS resource is measured.

[0125] 4. L1 beam measurement

[0126] In NR, the terminal can perform beam measurement on the CSI-RS resource sent by the serving cell. The terminal reports the measurement result to the network through L1 signaling, and the network usually uses the measurement result to select the transmission beam in the serving cell for scheduling the terminal. The serving cell indicates the frequency domain position (bandwidth and starting RB) and time domain position (periodicity and offset) of the to-be-measured CSI-RS resource in the measurement configuration.

[0127] The architecture of the embodiments of the present application is described above, and the method of the embodiments of the present application is described in detail below.

[0128] Referring to Figure 3 Fig. 1 is a flowchart of a communication method provided by an embodiment of the present application. Optionally, the method can be applied to the communication system described above, for example, the communication system shown in Fig. 1. As shown in Fig. 1, the method includes the following steps. Figure 1a Fig. 1 is a flowchart of a communication method provided by an embodiment of the present application. Optionally, the method can be applied to the communication system described above, for example, the communication system shown in Fig. 1. As shown in Fig. 1, the method includes the following steps.Figure 3 The illustrated communication method can include steps 301-302, as follows:

[0129] 301. The network device sends configuration information to the terminal, the configuration information being used to configure one or more reference signal resources. The configuration information includes configuration information of a first reference signal resource, wherein an instance corresponding to the first reference signal resource occurs on an SBFD symbol or a non-SBFD symbol, the first reference signal resource being any one of the one or more reference signal resources. Alternatively, the configuration information indicates that measurement and / or reporting are based on the SBFD symbol or the non-SBFD symbol. Accordingly, the terminal receives the configuration information.

[0130] The instance can be understood as one occurrence of a periodic resource. For example, if the period of a CSI-RS resource is 20 ms, the resource can have multiple instances at positions k, k+20, k+40, k+60, k+80…, where k is the time domain position of the first occurrence.

[0131] The instance corresponding to the first reference signal resource occurring on the SBFD symbol or the non-SBFD symbol can be understood as the instance corresponding to the first reference signal resource occurring only on the SBFD symbol, or the instance corresponding to the first reference signal resource occurring only on the non-SBFD symbol. Figure 4 If the instance of the illustrated resource occurs on both the non-SBFD symbol and the SBFD symbol, the resource cannot be used as the above-mentioned first reference signal resource (e.g., the instance indicated by x in the figure). Figure 4

[0132] It can be understood that the instance corresponding to the first reference signal resource occurring on the SBFD symbol or the non-SBFD symbol can be that all instances corresponding to all resources (each resource) in the one or more reference signal resources occur on the same symbol (SBFD symbol or non-SBFD symbol). It can also be that instances corresponding to some resources in the one or more reference signal resources occur on the SBFD symbol, and instances corresponding to other resources occur on the non-SBFD symbol, etc. For example, the one or more reference signal resources include resource 1 and resource 2. Wherein resource 1 and resource 2 both occur on the SBFD symbol. Or, resource 1 and resource 2 both occur on the non-SBFD symbol. Or, resource 1 occurs on the SBFD symbol, and resource 2 occurs on the non-SBFD symbol.

[0133] The instance corresponding to the above-mentioned first reference signal resource is all instances corresponding to the first reference signal resource. ​

[0134] For example, for one CSI-RS resource used for RLM / BFD / CBD measurement, the network device ensures that all instances of the resource only appear on SBFD symbols; for another CSI-RS resource used for RLM / BFD / CBD measurement, the network device ensures that all instances of the resource only appear on non-SBFD symbols. Alternatively, for all CSI-RS resources used for RLM / BFD / CBD measurement, the network device ensures that all instances of the resources only appear on non-SBFD symbols. For details of RLM / BFD / CBD measurement, refer to the foregoing description, which will not be repeated here.

[0135] For example, for any CSI-RS resource used for L3 mobility measurement, the network device ensures that all instances of the resource only appear on non-SBFD symbols of a neighbor cell that transmits the resource. For details of L3 mobility measurement, refer to the foregoing description, which will not be repeated here.

[0136] The configuration information indicating that measurement and / or reporting are based on the SBFD symbols or the non-SBFD symbols can be understood as per-resource indication or per-UE indication, and the present solution does not limit this.

[0137] In a possible implementation, when a first part of an instance corresponding to a second reference signal resource appears on the SBFD symbols and a second part of the instance appears on the non-SBFD symbols, measurement and / or reporting are based on the SBFD symbols or the non-SBFD symbols. The second reference signal resource is any one of the one or more reference signal resources.

[0138] For example, for a CSI-RS resource used for RLM / BFD / CBD measurement, if part of the instances of the resource appear on SBFD symbols and part of the instances of the resource appear on non-SBFD symbols, the terminal only measures the instances of the resource that appear on a specific type of symbol. For example, if the configuration information indicates that measurement and / or reporting of the resource are based on the SBFD symbols, the terminal only measures the instances of the resource that appear on the SBFD symbols, or if the configuration information indicates that measurement and / or reporting of the resource are based on the non-SBFD symbols, the terminal only measures the instances of the resource that appear on the non-SBFD symbols.

[0139] For example, for multiple CSI-RS resources for RLM / BFD / CBD measurement, each resource has some instances on SBFD symbols and some instances on non-SBFD symbols, the terminal only measures the instances of these resources that appear on a specific type of symbol. For example, if the above configuration information indicates that the terminal measures and / or reports based on SBFD symbols, the terminal only measures the instances of these resources that appear on SBFD symbols, or if the above configuration information indicates that the terminal measures and / or reports based on non-SBFD symbols, the terminal only measures the instances of these resources that appear on non-SBFD symbols.

[0140] For example, for three CSI-RS resources for RLM / BFD / CBD measurement, 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 instances are on non-SBFD symbols, the terminal only measures the instances of these resources that appear on a specific type of symbol. For example, if the above configuration information indicates that the terminal measures and / or reports based on non-SBFD symbols, the terminal only measures the instances of resource 2 and resource 3 that appear on non-SBFD symbols.

[0141] Optionally, for a CSI-RS resource for L3 mobility measurement, the network device indicates (per-resource or per-measurement reporting) the corresponding symbol type, for example, the network device indicates measurement and reporting for non-SFBD symbols. Alternatively, the network device indicates measurement and reporting for SBFD symbols and non-SBFD symbols, respectively, and the like, which is not limited by the present scheme.

[0142] In a 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 SBFD of the neighbor cell sending the resource, or indicates that the time domain and / or frequency domain configuration of SBFD of the neighbor cell is the same as that of the serving cell. For example, the network device indicates the period of occurrence of the intra-SBFD symbol of the neighbor cell and the starting time domain position of the SBFD symbol in the period, and the network device indicates the frequency domain positions of the intra-uplink subband and the intra-downlink subband of the neighbor cell. For another example, the network device indicates, by 1 bit, that the time domain and / or frequency domain configuration of SBFD of the neighbor cell is the same as that of the serving cell. In this way, the terminal can determine the SBFD time domain configuration of the neighbor cell, and further determine whether the CSI-RS resource sent by the neighbor cell is located on the SBFD symbol. If the terminal determines that the CSI-RS resource is located on the SBFD symbol of the neighbor cell, the terminal can determine the measurement bandwidth according to the frequency domain configuration of the SBFD of the neighbor cell, for example, only measure the part of the resource located in the downlink subband of the neighbor cell.

[0143] In this example, through the configuration information, the terminal can determine the symbol type for measurement, eliminate the possibility of cross-symbol type filtering in the measurement process, ensure the accuracy of the measurement and the consistency of the signal and interference plus noise ratio (SINR) / reference signal received power (RSRP) on different sample points in the filtering process. For example, in a general implementation, the CSI-RS used for RLM / BFD / CBD measurement can be limited to only non-SBFD symbols, which can accurately reflect the real link quality without CLI and avoid false triggering of link or beam failure due to the influence of CLI.

[0144] 302、The terminal measures the reference signal based on the configuration information.

[0145] In a possible implementation, for a CSI-RS resource used for measurement, if all instances of the CSI-RS resource are on a certain type of symbol, the terminal determines the measurement time according to the period of occurrence of the CSI-RS resource. The measurement may, for example, be RLM / BFD / CBD measurement, or CSI-RS resource used for L3 mobility measurement, or L1 beam measurement, and the like.

[0146] In another possible implementation, when a first part of the instance corresponding to the second reference signal resource is on the SBFD symbol and a second part is on the non-SBFD symbol, the terminal performs measurement and / or reporting based on the SBFD symbol or the non-SBFD symbol.

[0147] In a 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 occurring on the SBFD symbol or the non-SBFD symbol. For example, the measurement time T measure may be expressed as:

[0148]

[0149] T s = t s+1 - t s ifs<S;

[0150] T s = X ifs=S;

[0151] where S is an integer greater than or equal to 1, representing the number of samples measured, t s+1 and t s are the time points of the (s+1)th and s th instances of the resource occurring on the SBFD symbol or the non-SBFD symbol, and X is a number greater than or equal to 0, representing the processing time of each sample, for example, X = 1 ms or the length of a slot in ms.

[0152] In a possible implementation, for a CSI-RS resource used for L3 mobility measurement, if part of the instances of the resource occur on the SBFD symbol of a neighbor cell transmitting the resource and part of the instances occur on the non-SBFD symbol, the terminal only measures or respectively measures the instances of the resource occurring on a specific type of symbol, and determines the measurement time according to the time interval or the number of instances of the resource occurring on the specific type of symbol. For example, the terminal only measures the instances of the resource occurring on the non-SBFD symbol. Optionally, for the measurement of the instances occurring on the SBFD symbol, the measurement time is determined according to the time interval and / or the number of instances of the CSI-RS resource occurring on the SBFD symbol. For the measurement of the instances occurring on the non-SBFD symbol, the measurement time is determined according to the time interval and / or the number of instances of the CSI-RS resource occurring on the non-SBFD symbol, and so on.

[0153] In a possible implementation, for a CSI-RS resource used for L3 mobility measurement, if the resource is located on or corresponds to SBFD symbols of a neighbor cell which transmits the resource, the terminal measures the resource on the frequency domain location where the resource is available for measurement. For example, the resource is located within the bandwidth of a DL subband of the neighbor cell. In this way, the terminal can avoid measuring the part of the resource located within the uplink subband. Measuring the whole resource bandwidth of the resource will cause measurement error because the neighbor cell does not map the resource within the uplink subband.

[0154] In a possible implementation, for a CSI-RS resource used for L1 beam measurement, if part of the instances of the resource are on SBFD symbols of a neighbor cell which transmits the resource and part of the instances are on non-SBFD symbols, the terminal only measures or respectively measures the instances of the resource which occur on the specific type of symbols, and determines the measurement time according to the time interval or the number of instances in which the resource occurs on the specific type of symbols. Optionally, for the measurement of the instances which occur on the SBFD symbols, the measurement time is determined according to the time interval and / or the number of instances in which the CSI-RS resource occurs on the SBFD symbols. For the measurement of the instances which occur on the non-SBFD symbols, the measurement time is determined according to the time interval and / or the number of instances in which the CSI-RS resource occurs on the non-SBFD symbols.

[0155] In a possible implementation, when the UE measures at least one CSI-RS resource on the SBFD symbols (without limitation of specific conditions, for example, all instances of the resource are on the SBFD symbols, or part of the instances of the resource are on the SBFD symbols and part of the instances are on the non-SBFD symbols and the network device configures measurement reporting for the SBFD symbols, etc.), when at least one instance of the CSI-RS resource conflicts with dynamic scheduling of 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 influence of the conflict with the dynamic scheduling of UL. That is, when determining the measurement time, both the instances which do not conflict and the instances which conflict are considered.

[0156] Further, when one or more of the following conditions are met, it is determined that UL data is not transmitted on the SBFD symbols but CSI-RS is performed:

[0157] The one or more reference signal resources are used for radio link monitoring (RLM) measurement and T310 timer starting, the one or more reference signal resources are used for RLM, beam failure detection (BFD) or candidate beam detection (CBD) measurement, the one or more reference signal resources are used for RLM, BFD or CBD measurement and the network device indicates that the UL data is not transmitted on the SBFD symbol, the one or more reference signal resources are used for neighbor cell measurement and the quality of a serving cell is lower than a first preset threshold and / or the quality of a neighbor cell is higher than a second preset threshold, the one or more reference signal resources are used for neighbor cell measurement and the UL traffic 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 measurement and the network device indicates that the UL data is not transmitted on the SBFD symbol, or the one or more reference signal resources are used for beam measurement and there is a transmission configuration indication (TCI) switching or path-loss reference signal switching.

[0158] Correspondingly, when the one or more reference signal resources exist on the SBFD symbol, the network device does not schedule UL data on the SBFD symbol when one or more of the above conditions are met.

[0159] That is, when the conflict occurs, the UE does not send UL data but performs CSI-RS measurement when the above conditions are met. Among them, the above conditions for RLM measurement and T310 timer start, that is, when the measurement of In-sync is performed. In this way, unnecessary triggering of link failure or beam failure due to untimely measurement is avoided. The above first preset threshold and / or second preset threshold can be indicated by the above configuration information. Alternatively, the network device indicates the preset threshold of the quality of the serving cell and / or the neighboring cell, which is used to solve the conflict between CSI-RS measurement on the SBFD symbol of the serving cell and dynamically scheduled UL. For example, the terminal determines not to send UL according to the quality of the serving cell and / or the quality of the neighboring cell and the preset threshold indicated by the network device. Alternatively, the quality of the neighboring cell is determined according to the measurement on the associated SSB corresponding to the resource. In this way, it is beneficial for the terminal to obtain measurement results in time when at the cell edge. The above resource is used for neighboring cell measurement, and the service of the UL does not include signaling transmission or high-priority data, that is, when the service of the UL does not include signaling transmission or high-priority data, UL data is not sent. For example, the signaling transmission includes reporting of measurement results, etc. For another example, the terminal determines not to send UL according to the service of the UL. In this way, the influence of measurement on important UL service is avoided, and when the priority of the UL service is low, measurement is prioritized to ensure timely mobility measurement. For another example, if the CSI-RS measurement occurs during TCI switching or path-loss reference signal switching, the terminal does not send UL but performs CSI-RS measurement, and the measurement time does not consider the number of instances of conflict with dynamically scheduled UL. In this way, important processes such as TCI switching or path-loss reference signal switching are ensured to be completed in time.

[0160] In a possible implementation, when the above conflict occurs, the measurement time is determined based on the time interval and / or the number of instances in which the resource occurs on the SBFD symbol. For this part, refer to the foregoing description, which will not be repeated here.

[0161] In a possible implementation, when measuring the one or more reference signal resources on the SBFD symbol, when at least one instance of the CSI-RS resource conflicts with dynamically scheduled UL transmission, for example, when the above conditions are not met, UL data is sent on the SBFD symbol without performing CSI-RS measurement. Alternatively, 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 conflict between the one or more reference signal resources and dynamically scheduled UL.

[0162] For example, the measurement time T of L1 beam measurement measure which can be expressed as:

[0163] T measure = max(T Report , ceil((M+L1)*P)*T CSI-RS );

[0164] Wherein, T Report is a network configured reporting period, M is a measured sample number, L1 is a number of instances of CSI-RS resource and dynamically scheduled UL conflict within T measure , P is a relaxation factor considering the conflict between CSI-RS resource and measurement gap, T CSI-RS is a period of CSI-RS resource. L1≤L1 max , L1 max is a standard predefined maximum extension number. ceil((M+L1)*P) represents rounding up (M+L1)*P.

[0165] For example, the terminal sends UL when measuring out-of-sync (before T310 starts). For another example, the terminal sends UL data when measuring BFD. For another example, the terminal determines to send UL according to the quality of the serving cell and / or the quality of the neighbor cell and the preset threshold indicated by the network device. For another example, the terminal determines to send UL according to the UL service. For example, when the UL service is signaling transmission (including measurement reporting) or high priority data, UL transmission is preferred, otherwise, CSI-RS measurement is preferred.

[0166] It should be noted that the above conditions are only one example when a conflict occurs, and the present solution does not limit this.

[0167] Further, the above examples at least applicable to RLM / BFD / CBD measurement define the method for terminal to determine the symbol type for RLM / BFD / CBD measurement and the corresponding measurement time. By limiting the network implementation or by network configuration or by specifying the terminal behavior, the possibility of cross-symbol type filtering in the RLM / BFD / CBD measurement process is eliminated, ensuring the accuracy of RLM / BFD / CBD measurement and the consistency of SINR / RSRP on different samples in the filtering process. In general implementation, the CSI-RS used for RLM / BFD / CBD measurement can be limited to non-SBFD symbols, which can accurately reflect the true link quality without cross link interference (CLI), avoiding false triggering of link or beam failure due to CLI. The example also defines the priority when the UL of dynamic scheduling conflicts with RLM / BFD / CBD measurement. Prior measurement is beneficial for the terminal to judge the link quality more timely. In particular, when detecting link problems or beam failure, the UL is likely to be incorrectly received, and timely recovery of the link or beam is more important than the UL, and priority In-sync measurement and CBD measurement are beneficial for timely recovery of the link or beam, avoiding unnecessary triggering of link failure or beam failure.

[0168] Further, the above examples at least applicable to L3 mobility measurement define the method for terminal to determine whether the CSI-RS resource used for L3 mobility measurement in the neighbor cell is located in the SBFD symbol, and further specify the method for terminal to determine the frequency domain that can be used when a certain resource is located in the SBFD symbol of the neighbor cell, enabling the terminal to correctly measure the CSI-RS resource of the neighbor cell that has enabled SBFD. The example also defines the method for terminal to determine the symbol type for L3 mobility measurement and the corresponding measurement time, enabling the terminal to measure for a certain symbol type of the neighbor cell, or measure for different symbol types of the neighbor cell respectively. The example also defines the priority when the UL of dynamic scheduling conflicts with L3 mobility measurement and the corresponding measurement time, which clearly defines the terminal transmission behavior.

[0169] Further, the above examples at least applicable to L1 beam measurement define the measurement time for terminal to perform L1 beam measurement on different types of symbols. The example also defines the priority when the UL of dynamic scheduling conflicts with L1 beam measurement. Prior measurement during special procedures such as TCI switching or path-loss reference signal switching is beneficial for the terminal to complete these procedures more timely, avoiding the increase of the time delay of these procedures due to dynamic UL, affecting the DL or UL data after these procedures.

[0170] The terminal performs measurement of a reference signal based on configuration information sent by a network device, so that the terminal determines a symbol type for measurement, eliminates the possibility of cross-symbol type filtering in the measurement process, and ensures the accuracy of the measurement and the consistency of SINR / RSRP on different sample points in the filtering process.

[0171] Referring to Figure 5 FIG. 6 is a flowchart of another communication method provided by an embodiment of the present application. Optionally, the method can be applied to the communication system described above, for example Figure 1a the communication system shown in FIG. 1. The communication method shown in FIG. 6 can include steps 501-502, which are as follows. Figure 5

[0172] 501. The network device sends configuration information to the terminal, and the configuration information is used to configure one or more reference signal resources. Correspondingly, the terminal receives the configuration information.

[0173] 502. The terminal measures the reference signal based on the configuration information and a predefined rule. The predefined rule includes measuring and / or reporting based on SBFD symbols or non-SBFD symbols.

[0174] The difference between the embodiment shown in FIG. 6 and the embodiment shown in FIG. 5 is that the example does not need to be configured by configuration information, but determines to measure and / or report based on the set symbols based on a predefined rule. Figure 3

[0175] In one possible implementation, it is predefined to measure and / or report based on non-SBFD symbols. Alternatively, it is predefined to measure and / or report based on SBFD symbols.

[0176] In another possible implementation, it is predefined to determine the symbols based on a condition. For example, when there is an SSB for measurement, the UE only uses the instance of the CSI-RS resource on the SBFD symbol for measurement. For another example, when there is at least one CSI-RS resource that only appears on non-SBFD symbols for measurement, the UE only uses the instance of the CSI-RS resource on the SBFD symbol for measurement, and so on. Of course, other conditions are also possible, and the present solution does not limit this.

[0177] In one possible implementation, when a first part of an instance corresponding to a second reference signal resource appears on the SBFD symbol and a second part appears on the non-SBFD symbol, measurement and / or reporting are performed based on the SBFD symbol or the non-SBFD symbol, where the second reference signal resource is any one of the one or more reference signal resources.

[0178] ​​For example, for a CSI-RS resource used for RLM / BFD / CBD measurement, if part of its instances are on SBFD symbols and part of its instances are on non-SBFD symbols, the terminal only measures the instances of this resource that occur on the specific type of symbols. For example, if it is predefined that this resource is measured and / or reported based on SBFD symbols, the terminal only measures the instances of this resource that occur on SBFD symbols, or if it is predefined that this resource is measured and / or reported based on non-SBFD symbols, the terminal only measures the instances of this resource that occur on non-SBFD symbols.

[0179] For example, for a CSI-RS resource used for RLM / BFD / CBD measurement, if part of its instances are on SBFD symbols and part of its instances are on non-SBFD symbols, the terminal only measures the instances of this resource that occur on the specific type of symbols. For example, if it is predefined that this resource is measured and / or reported based on SBFD symbols, the terminal only measures the instances of this resource that occur on SBFD symbols, or if it is predefined that this resource is measured and / or reported based on non-SBFD symbols, the terminal only measures the instances of this resource that occur on non-SBFD symbols.

[0180] For example, for a CSI-RS resource used for RLM / BFD / CBD measurement, if part of its instances are on SBFD symbols and part of its instances are on non-SBFD symbols, the terminal only measures the instances of this resource that occur on the specific type of symbols. For example, if it is predefined that this resource is measured and / or reported based on SBFD symbols, the terminal only measures the instances of this resource that occur on SBFD symbols, or if it is predefined that this resource is measured and / or reported based on non-SBFD symbols, the terminal only measures the instances of this resource that occur on non-SBFD symbols.

[0181] In a 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 in which the second reference signal resource occurs on the SBFD symbols or the non-SBFD symbols. For the calculation of the measurement time, reference can be made to the foregoing description, which will not be repeated here.

[0182] In a possible implementation, when the UE measures at least one CSI-RS resource on the SBFD symbol (the specific condition is not limited, for example, all instances of the resource are on the SBFD symbol, or part of the instances of the resource are on the SBFD symbol and part of the instances are on the non-SBFD symbol, and the network device configures the measurement reporting for the SBFD symbol, etc.), when at least one instance of the CSI-RS resource conflicts with dynamic scheduling of uplink (UL) data transmission, the terminal does not send the UL data but performs the CSI-RS. Optionally, in this case, the measurement time does not consider the impact of the conflict with the dynamic scheduling of the UL. That is, when determining the measurement time, both the instances that do not conflict and the instances that conflict are considered.

[0183] Further, when one or more of the following conditions are met, it is determined that the UL data is not sent on the SBFD symbol but the CSI-RS is performed:

[0184] The one or more reference signal resources are used for radio link monitoring (RLM) measurement and a T310 timer is started, the one or more reference signal resources are used for RLM, beam failure detection (BFD) or candidate beam detection (CBD) measurement, the one or more reference signal resources are used for RLM, BFD or CBD measurement and the network device indicates that the UL data is not sent on the SBFD symbol, the one or more reference signal resources are used for neighbor cell measurement 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 measurement and the traffic of the UL 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 measurement and the network device indicates that the UL data is not sent on the SBFD symbol, and the one or more reference signal resources are used for beam measurement and when a transmission configuration indication (TCI) switching or a path-loss reference signal switching occurs.

[0185] That is, when the conflict occurs, the UE does not send the UL data but performs the CSI-RS measurement when the above conditions are met.

[0186] In a possible implementation, when the above conflict occurs, the measurement time is determined based on the time interval and / or the number of instances in which the resource appears on the SBFD symbol. For the introduction of this part, refer to the foregoing description, which is not repeated here.

[0187] 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.

[0188] 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.

[0189] Reference Figure 6 The diagram shown is a flowchart illustrating another communication method provided in an embodiment of this application. Optionally, this method can be applied to the aforementioned communication system, for example... Figure 1a The communication system shown. (As shown) Figure 6 The communication method shown may include steps 601-602, as follows:

[0190] 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.

[0191] 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:

[0192] The one or more reference signal resources are used for radio link monitoring (RLM) measurement and T310 timer starting, the one or more reference signal resources are used for RLM, beam failure detection (BFD) or candidate beam detection (CBD) measurement, the one or more reference signal resources are used for RLM, BFD or CBD measurement and the network device indicates that the UL data is not transmitted on the SBFD symbol, the one or more reference signal resources are used for neighbor cell measurement and the quality of a serving cell is lower than a first preset threshold and / or the quality of a neighbor cell is higher than a second preset threshold, the one or more reference signal resources are used for neighbor cell measurement and the traffic of the UL does not include signaling transmission or preset priority data, the one or more reference signal resources are used for neighbor cell measurement and the network device indicates that the UL data is not transmitted on the SBFD symbol, or the one or more reference signal resources are used for beam measurement and when a TCI switches or a path-loss reference signal switches.

[0193] In a possible implementation, the terminal completes measurement of the reference signal within a measurement time, which is determined based on a time interval and / or a number of instances in which the one or more reference signal resources occur on the SBFD symbol. For calculation of the measurement time, refer to the foregoing description, which is not repeated here.

[0194] In a possible implementation, the configuration information further indicates one or more of the following: no UL data is transmitted 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 neighbor cell.

[0195] In a possible implementation, when the one or more reference signal resources are measured on the SBFD symbol, the measurement of the reference signal is completed within a measurement time when UL data is transmitted on the SBFD symbol, and the measurement time is extended according to a number of instances in which the one or more reference signal resources conflict with dynamically scheduled UL. For calculation of the measurement time, refer to the foregoing description, which is not repeated here.

[0196] In the embodiments of the present application, when the terminal is in conflict with dynamically scheduled UL, the measurement is prioritized, which helps the terminal to more timely judge the link quality, avoid unnecessary triggering of link failure or beam failure, ensure that the terminal can obtain measurement results in time when at the cell edge, and ensure that important processes are completed in time.

[0197] It should be noted that, in each of the embodiments of the present application, the terms and / or descriptions of different embodiments are consistent and can be mutually referenced if there is no special description and logical conflict.
