Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and more particularly, to a method and apparatus in a node for wireless communication. BACKGROUND

[0002] Currently, in a new radio (NR) system, each synchronization signal broadcast channel block (SS / PBCH block, SSB) is used for initial access and synchronization, and the SSB is composed of a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH). In order to provide robust and instant services for terminal devices, network devices need to periodically transmit SSBs. However, periodic transmission of SSBs not only occupies redundant resources, but also causes excessive energy consumption of network devices. Network energy saving is a major requirement for 6G system design. Therefore, how to optimize the synchronization signal broadcast channel block so that the 6G system can better adapt to the current energy saving demand and the future evolution trend of the 6G physical layer is a problem that needs to be solved at the beginning of the discussion of the 6G system.

[0037] Communication system architecture The wireless communication system of embodiments of the present application can include network devices and terminal devices. The network device can be a device that communicates with the terminal device. The network device can provide communication coverage for a specific geographic area and can communicate with terminal devices located within the coverage area.

[0038] Figure 1 An example wireless communication system 100 includes a network device 110 and a plurality of terminal devices, such as terminal device 120a to terminal device 120j. Optionally, the wireless communication system 100 can include multiple network devices and each network device can include other numbers of terminal devices within its coverage, which are not limited in embodiments of the present application.

[0039] Optionally, the wireless communication system can also include network controllers, mobile management entities, and other network entities, which are not limited in embodiments of the present application.

[0040] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, for example: a 5th-generation (5G) system or a new radio (NR) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a 5G advanced system, a low-power communication system, and the like. The technical solutions provided in the present application can also be applied to future communication systems, such as a 6th-generation (6G) mobile communication system, a satellite communication system, and the like.

[0041] In the communication technology before the NR system, for a terminal device, the working mode of the terminal device can support multiple communication technologies at the same time, and each communication technology corresponds to a multiple access mode. However, with the evolution of technology, in the communication technology of the NR system and after the NR system, a single communication system can support multiple multiple access modes.

[0042] It should be understood that the multiple access mode is also called a multiple access mode or a multiple access technology, which refers to a technology for solving how to efficiently share a wireless resource (such as time / frequency / space / carrier) when multiple users access a network (such as a cell of mobile communication or a wireless local area network). That is, when multiple users share a wireless resource, the resource is divided according to time, frequency, space, coding, subcarrier, and the like, so that different users use (or access) the divided resource for communication in different division modes. Occupying different division resources is like having different addresses, and the same wireless resource can have multiple addresses, so it is called multiple access. Multiple access modes are roughly divided into two categories: orthogonal multiple access (OMA), that is, there is no interference between users; and non-orthogonal multiple access (NOMA), in which the signal of each user can interfere with other users.

[0043] The multiple access schemes contemplated by the present application include, but are not limited to, the following: frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), space division multiple access (SDMA), carrier sense multiple access with collision avoidance (CSMA / CA) non-orthogonal multiple access (NOMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and other multiple access schemes.

[0044] The symbols contemplated by the present application include, but are not limited to, the following: multi-carrier symbols, orthogonal frequency division multiplexing (OFDM) symbols, discrete fourier transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) symbols, single-carrier frequency division multiple access (SC-FDMA) symbols, filter bank multi carrier (FBMC) symbols.

[0045] The symbols contemplated by the present application can include cyclic prefix (CP).

[0046] The following description describes a new radio (NR) system for the purpose of example and uses NR terminology in much of the following description, but the techniques can also be applied to applications other than NR system applications, such as a 6th Generation (6G) communication system, a 6th Generation Radio (6GR) communication system. A wireless communication system includes terminal devices and network side devices.

[0047] The terminal device can be a mobile phone, a tablet personal computer, a laptop computer, also known as a notebook computer, a personal digital assistant (PDA), a palm computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted device (VUE), a pedestrian terminal (PUE), a smart home (a home device with wireless communication function, such as a refrigerator, a television, a washing machine, or furniture, etc.), a game console, a personal computer (PC), a teller machine, or a self-service machine, etc. The wearable device includes a smart watch, a smart bracelet, a smart earphone, smart glasses, smart jewelry (a smart bracelet, a smart necklace, a smart ring, a smart necklace, a smart ankle bracelet, a smart ankle chain, etc.), a smart wristband, smart clothing, etc. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in V2X or D2D, etc. For example, a cell phone and a car communicate with each other using sidelink signals. The cell phone and the smart home device communicate without relaying the communication signal through the base station. In addition, the terminal can also support multiple communication modes, i.e., a multi-mode terminal, and the present application is also applicable to the multi-mode terminal. It should be noted that the specific type of terminal device is not limited in the embodiments of the present application.

[0048] In some embodiments, the terminal device can be a station (ST) in a WLAN. In some embodiments, the terminal device can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device having wireless communication function, a computing device, or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a next-generation communication system (for example, an NR system), or a terminal device in a future evolved public land mobile network (PLMN) network, and the like.

[0049] The network-side device can include an access network device or a core network device, where the access network device can also be referred to as a radio access network device, a radio access network (RAN), a radio access network function, or a radio access network unit. The access network device can include a base station, a WLAN access point, or a WiFi node, etc. The base station can broadly cover various names in the following or be replaced by the following names, such as: Node B, evolved Node B (eNB), next generation Node B (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station (MeNB), secondary station (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, network communication device, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. The base station can also refer to a communication module, modem, or chip used in the aforementioned devices or apparatuses. The base station can also be a mobile switching center, a device assuming a base station function in D2D, V2X, M2M communication, a network-side device in a 6G network, a device assuming a base station function in a future communication system, etc. The base station can support networks of the same or different access technologies. Embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0050] It should be understood that the 6G system will adopt a more flexible and efficient multiple access mode. For example, the non-orthogonal multiple access (NOMA) technology transmits the data of multiple users in the same frequency band at the same time, and optimizes resource allocation and interference management by utilizing the differences between users; sparse codebooks and multi-element modulation technologies can be used to improve spectral efficiency and transmission performance. Based on interleaved multiple access, multi-user shared access-based multiple access, resource expansion-based multiple access, and UMA (unsourced multiple access).

[0051] The terms "system" and "network" are often used interchangeably in the embodiments of the present application, and the described technology can be used in the above-mentioned systems and radio technologies, as well as other systems and radio technologies.

[0052] It is worth noting that the base station can be fixed or mobile. For example, a helicopter or a drone can be configured to act as a mobile base station, and one or more cells can move according to the location of the mobile base station. In other examples, a helicopter or a drone can be configured to act as a device that communicates with another base station.

[0053] In some deployments, the network device in the embodiments of the present application can refer to a CU or a DU, or the network device includes a CU and a DU. The gNB can also include an AAU.

[0054] In the embodiments of the present application, the network device can serve a cell, and a terminal device communicates with the network device through transmission resources (for example, frequency domain resources, or spectrum resources) used by the cell. The cell can be a cell corresponding to the network device (for example, a base station), and the cell can belong to a macro base station or a base station corresponding to a small cell (small cell). The small cell in this context can include a metro cell, a micro cell, a pico cell, a femto cell, etc., which have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0055] In addition, the network device and the terminal device can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the scenarios in which the network device and the terminal device are located.

[0056] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0057] Figure 2A schematic diagram of a network architecture 200 of one embodiment of the present application is shown by way of example. The network architecture 200 illustrates a network architecture of a 5G NR / LTE / LTE-A system, which in turn can be referred to as a 5G system (5GS) / evolved packet system (EPS) network architecture. The network architecture 200 includes a network device 110, a terminal device 120, a 5G core network (5GC) / evolved packet core (EPC) 210, a home subscriber server (HSS) / unified data management (UDM) 220, and at least one of an Internet service 230. Figure 2 The network device and the terminal device in the network architecture 200 are respectively exemplified by way of example as a RAN and a UE.

[0058] As Figure 2As shown, network equipment 110 provides user plane protocol and control plane protocol termination toward terminal equipment 120. Network equipment 110 is connected to 5GC / EPC 210 over an S1 / NG interface. 5GC / EPC 210 includes mobility management entity (MME) / authentication management field (AMF) / session management function (SMF) 211, other MME / AMF / SMF 214, service gateway (S-GW) / user plane function (UPF) 212, and packet data network gateway (P-GW) / UPF 213. MME / AMF / SMF 211 is the control node that handles signaling between terminal equipment 120 and 5GC / EPC 210. Generally, MME / AMF / SMF 211 provides bearer and connection management. All user internet protocol (IP) packets are transferred through S-GW / UPF 212, which itself is connected to P-GW / UPF 213. The P-GW provides UE IP address allocation as well as other functions. P-GW / UPF 213 is connected to internet services 230. Internet services 230 include operator corresponding internet protocol services, which can include the Internet, intranet, IP multimedia subsystem (IMS), and packet switched streaming services, among others. As can be seen, network architecture 200 provides packet switched services, however those of skill in the art will readily understand that the various concepts presented throughout this application can be extended to networks or other cellular networks that provide circuit switched services.

[0059] Figure 3A and Figure 3B Figures 1A and 1B respectively illustrate a wireless protocol stack architecture diagram of one embodiment of the present application. Figure 3A and Figure 3B The 5G wireless protocol stack is taken as an example for introduction. The 5G wireless protocol stack is divided into two planes: a user plane (UP) protocol stack and a control plane (CP) protocol stack. The user plane protocol stack is the protocol cluster adopted by user data transmission, and the control plane protocol stack is the protocol cluster adopted by control signaling transmission of the 5G system. The names of the layers of each protocol stack are as follows: As Figure 3AAs shown, the user plane protocol stack, from top to bottom, includes: the Service Data Adaptation Protocol (SDAP) layer, the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, the Medium Access Control (MAC) layer, and the Physical (PHY) layer.

[0060] like Figure 3B As shown, the control plane protocol stack, from top to bottom, includes: non-access stratum (NAS); radio resource control (RRC) layer, PDCP layer, RLC layer, MAC layer, and PHY layer.

[0061] It should be understood that the different layers in the above protocol stack have different functions, and they work together through inter-layer interaction to achieve communication between terminal devices and network devices. With the development of artificial intelligence technology, AI-assisted computing has permeated the processing implementation methods of the above protocol stack. For example, the scheduling algorithm of the MAC layer and the encoding / decoding algorithm of the PHY layer can apply artificial intelligence algorithms to improve the performance of communication algorithms.

[0062] As an example, Figure 3A and Figure 3B The wireless protocol architecture described herein is applicable to the first node in this application.

[0063] As an example, Figure 3A and Figure 3B The wireless protocol architecture described herein is applicable to the second node in this application.

[0064] It should be understood that some functionalities in a wireless protocol architecture can also be implemented in one or more devices. For example, the functions of different layers in the control plane protocol stack can be implemented by multiple nodes on the network side.

[0065] It should be understood that the interpretation of the terminology in the embodiments of this application may refer to the TS36, TS37 and TS38 series of specifications of the 3rd generation partnership project (3GPP), but may also refer to the specifications of the Institute of Electrical and Electronics Engineers (IEEE).

[0066] For the convenience of understanding, some related technical knowledge involved in the embodiments of the present application is introduced first. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way as optional schemes, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0067] Carrier aggregation (CA) To meet the peak rate of a single terminal device and improve system capacity, CA technology can be used to increase the transmission bandwidth of the system. The CA technology is to combine two or more carriers to form a data channel to increase the data capacity. With the existing network spectrum, the CA technology enables operators to provide higher uplink (UL) and downlink (DL) data rates, thus improving network performance and ensuring high-quality user experience.

[0068] In the 4G system (or LTE system), 2-5 LTE member carriers or component carriers (CCs) can be aggregated together to achieve higher transmission bandwidth, for example, a maximum transmission bandwidth of 100 MHz, thereby effectively improving the uplink and downlink transmission rate. For example, as shown in Figure 4 5 20MHz carriers can be aggregated to form a 100MHz transmission bandwidth, and the terminal device can determine the maximum number of carriers that can be used for uplink and downlink transmission at the same time according to its capability.

[0069] In the LTE system, the CA technology supports continuous or discontinuous carrier aggregation, and the maximum resource that can be used by each carrier is 110 resource elements (REs). Each terminal device uses an independent hybrid automatic repeat request (HARQ) entity on each carrier, and each RE can only be mapped to a specific carrier. The physical downlink control channel (PDCCH) on each carrier is independent of each other, and the design of the eighth release (release-8, Rel-8 / R8) of the LTE can be reused, that is, the PDCCH of each carrier can be used to allocate resources for the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH) of each carrier, or the PDCCH channel on one carrier can be used to schedule the allocation of uplink and downlink resources of multiple carriers through the carrier indicator field (CIF).

[0070] In the tenth release (release-10, Rel-10 / R10) of the LTE, the number of carriers that can be aggregated is increased, for example, up to 5 carriers can be supported for aggregation. And in subsequent versions, the carrier aggregation is also constantly evolving, for example, as shown in Figure 5 The ability of carrier aggregation is further enhanced in the 5G system.

[0071] The 5G system (or new radio (NR) system) is rooted in the protocol standards of the LTE and Wi-Fi, and is a brand new radio frequency interface and radio frequency access network, which uses the best technology and means in the LTE system to meet the new requirements proposed by standardization organizations. The CA technology makes an important contribution to improving the user data throughput of the LTE system, and will also play an equally important role in the 5G system. In order to increase the capacity, global operators are actively adding CA frequency bands and functions. As an example, as shown in Table 1, different countries and regions design corresponding CA types and functions for different frequency bands.

[0072] Table 1

[0073] As Figure 5As shown, after the introduction of CA (Carrier Aggregation) technology from the 4G LTE-Advanced protocol, the initial aggregation involved 5 carriers, each with a bandwidth of 20MHz, resulting in a total bandwidth of 100MHz. This was later extended to the aggregation of 32 carriers, achieving a total bandwidth of 640MHz. With the development of communication technology, the number of carriers that can be aggregated in 5G systems has gradually increased to 16, with each carrier having a larger bandwidth. In Sub-6G systems, the maximum bandwidth of a single carrier reaches 100MHz, allowing 16 carriers to aggregate to form a bandwidth of 1.6GHz. In the millimeter-wave band, the maximum bandwidth of a single carrier reaches 400MHz, allowing 16 carriers to aggregate to form a bandwidth of 6.4GHz.

[0074] As mentioned earlier, when multiple carriers are aggregated together, they need to coordinate with each other. Therefore, these carriers are divided into primary carriers and secondary carriers. The primary carrier is used to carry signaling and manage other carriers; it can also be called the primary cell (PCell). Secondary carriers are used to extend bandwidth and enhance data rate; their addition and removal are determined by the primary carrier, and they can also be called secondary cells (SCells). The primary and secondary carriers are relative to the terminal device; different terminal devices may use different primary and secondary carriers. Furthermore, the multiple carriers participating in aggregation are not limited to the same base station; for example, these carriers can come from adjacent base stations.

[0075] SSB Synchronization signal blocks / physical broadcast channel blocks (SS / PBCH blocks, SSBs) are transmitted via beam scanning. Multiple SSBs are typically transmitted within a cell to complete one beam scan, ensuring SSB coverage of the entire cell's service area. The SSBs required to complete one beam scan can form an SSB burst set, or simply an SSB burst. The transmission configuration of the SSB burst set in time, frequency, or spatial domain is usually described by a pattern. For example... Figure 6 The SSB beam scan and SSB burst set transmission times are shown, where, Figure 6 (a) shows the airspace beam that transmits each SSB. Figure 6(b) in FIG. 1 shows the time-domain location of transmitting each SSB. The pattern of SSB burst set can be different under different frequency bands and configurations. For example, under different frequency bands, the maximum number of SSBs that one SSB burst set can include can be 4, 8 and 64, etc., and different SSBs in the SSB burst set have different SSB indexes. Figure 6 is taken as an example that one SSB burst set includes 8 SSBs, with indexes SSB 0 to SSB 7. As an example, Table 2 shows the pattern information of SSB transmission under different sub-carrier spaces (SCS) of SSB.

[0076] Table 2

[0077] In the NR system, each synchronization signal broadcast channel block (SS / PBCH block, SSB) is used for initial access and synchronization, and the SSB is composed of four parts of primary synchronization signals (PSS), secondary synchronization signals (SSS), a physical broadcast channel (PBCH) and a demodulation reference signal for PBCH (PBCH-DMRS). As an example, as shown in the SSB structure shown in Figure 7 , the SSB occupies 4 OFDM symbols in the time domain and 240 subcarriers, i.e. 20 physical resource blocks (PRBs), in the frequency domain, with the number from 0 to 239.

[0078] Wherein, the PSS and SSS are generated by m-sequence and Gold code respectively, and the user equipment receives the PSS and SSS to obtain the PCI (Physical Cell Identification). The content carried by the PBCH is partly from the MIB (main information block) of the upper layer, and the rest is provided by the physical layer. The MIB includes the high 6 bits of the system frame number, the CORESET and monitoring occasion, the residence indication, the intra-frequency cell reselection indication and other information. The information provided by the physical layer includes the low 4 bits of the system frame number, the SSB frequency domain offset and SSB index, the half-frame indication and the cyclic check. When the PBCH content in the SSB is associated with the CORESET#0 of the Type0-PDCCH, the SSB can be referred to as a cell defining SSB (CD-SSB); when the PBCH in the SSB is not associated with the CORESET#0, the SSB can be referred to as a non-cell defining SSB (NCD-SSB).

[0079] It can be seen that the SSB structure of NR is relatively fixed and not efficient and flexible enough. Specifically, on the one hand, in the dual connection scenario, the user equipment needs to be completely accessed and camped in the primary cell, and in the secondary cell configured for the user equipment by the upper layer, only synchronization needs to be completed, and then data plane tasks can be ensured to arrive, measurement and feedback can be successful. At this time, the content of the PBCH in the SSB is not necessary information, and the periodic transmission of the SSB not only occupies redundant resources, but also causes excessive energy consumption of the network equipment. On the other hand, the uplink and downlink transmission of NR has a large number of beams, and there are a large number of periodically transmitted measurement signals (such as CSI-RS and SSB) associated with the beams, which occupy air interface resources. When using SSB as a measurement signal, since the base station and the user equipment pre-store a lot of information after connection establishment, the NCD-SSB at this time does not need the PBCH information in the SSB.

[0080] From the perspective of standard evolution, the synchronization signal has been adapting to the changes of the system from 4G to 5G. The bandwidth of the 4G system is maximally 20MHz, and its broadcast channel and synchronization signal are sent separately, fixedly occupying the central 6 resource blocks (RB) of the first 4 symbols of the time slot 1. From 5G, the large bandwidth makes the process of UE searching for the synchronization block slower, and multi-beam transmission is introduced, so NR collects the synchronization signal and the broadcast channel in the SSB, periodically transmits the SSB burst set containing multiple SSBs, and each SSB in the SSB burst set can use different beams for beam scanning or use the same beam for beam scanning, so that the UE can perform combined reception.

[0081] For 6G, the system bandwidth can be as high as 200MHz or even 400MHz, and the design of SSB needs to be further optimized. The smaller the bandwidth of SSB is, the larger the channel grid can be, and the simpler the user equipment searches for SSB. On the other hand, network energy saving is a major requirement for 6G system design, and the periodically transmitted SSB will consume a lot of network energy. Therefore, how to design a flexible and optimized synchronization signal and broadcast channel so that the resource overhead is reduced and the configuration is more flexible is the main problem to be solved in the present application.

[0082] It should be understood that all or part of the following embodiments of the present application can solve at least one of the following technical problems or all technical problems.

[0083] One of the technical problems to be solved by the present application is that the periodically transmitted traditional SSB causes low network energy efficiency; One of the technical problems to be solved by the present application is that the periodically transmitted traditional SSB causes excessive network device energy consumption; One of the technical problems to be solved by the present application is that the traditional SSB occupies a large bandwidth in the frequency domain and multiple symbols in the time domain, and the network power consumption is large for each transmission of SSB; One of the technical problems to be solved by the present application is that the PBCH in the traditional SSB occupies a large amount of time domain and frequency domain resources, and consumes a large amount of power when transmitting.

[0084] One of the technical problems to be solved by the present application is that the traditional fixed SSB structure not only occupies redundant resources, but also increases the power consumption overhead of network devices and user equipment.

[0108] In some embodiments, the second burst set comprises Y second-type candidate signal blocks, and each of the second-type candidate signal blocks in the second burst set comprises at least one broadcast channel block.

[0113] As an embodiment, the second burst set includes Y second-type candidate signal blocks, each of the Y second-type candidate signal blocks is composed of a PBCH and a PBCH-DMRS.

[0114] In some embodiments, the second burst set includes Y second-type candidate signal blocks, each of the second-type candidate signal blocks in the second burst set includes at least one broadcast channel block, each of the second-type candidate signal blocks in the second burst set does not include a PSS.

[0115] In some embodiments, the second burst set includes Y second-type candidate signal blocks, each of the second-type candidate signal blocks in the second burst set includes at least one broadcast channel block, each of the second-type candidate signal blocks in the second burst set does not include a SSS.

[0116] In some embodiments, the second burst set includes Y second-type candidate signal blocks, each of the second-type candidate signal blocks in the second burst set includes at least one broadcast channel block, and each of the second-type candidate signal blocks in the second burst set does not include a PSS and an SSS.

[0117] In some embodiments, the first burst set includes X first-type candidate signal blocks, and the second burst set includes Y second-type candidate signal blocks. X and Y are both positive integers. Optionally, X and Y are not equal, e.g., X is greater than Y. Exemplarily, as shown in Figure 9A As shown, the UE receives one first burst set and one second burst set from the base station in a configuration period of 20 ms, the first burst set includes 7 synchronization signal blocks, and the second burst set includes 2 PBCHs. In this example, because the time-domain interval from the synchronization signal to the nearest PBCH block can be determined by the configuration period, the UE can better control the detection latency while ensuring timely synchronization.

[0118] In some embodiments, the first node receives a greater number of first burst sets than second burst sets in the first configuration period. Exemplarily, as shown in Figure 9B or Figure 9C As shown, the UE receives 3 first burst sets and only 2 second burst sets in a configuration period of 20 ms.

[0119] As an example, the first node receives the first burst set in a first period and receives the second burst set in a second period in the first configuration period, and the second period is greater than the first period. Exemplarily, as shown in Figure 9D As shown, the UE receives four first burst sets in a first period and receives two second burst sets in a second period in the first configuration period.

[0120] As an example, the first period and the second period each include a positive integer number of time slots.

[0121] In some embodiments, the first burst set includes X first-type candidate signal blocks, and the second burst set includes Y second-type candidate signal blocks. In the first configuration period, the first node receives a greater number of first burst sets than second burst sets, and the total number of first-type candidate signal blocks is greater than the total number of second-type candidate signal blocks. Exemplarily, as shown in Figure 9E As shown, the first burst set includes four first-type candidate signal blocks, and the second burst set includes four second-type candidate signal blocks, but in one configuration period, the first node receives three burst sets, i.e., receives three first burst sets and two second burst sets. Among them, the first-type candidate signal blocks of the first burst set are associated with the nearest second-type candidate signal blocks backward in time domain, and in a single configuration period, the total number of first-type candidate signal blocks is greater than the total number of second-type candidate signal blocks.

[0122] It should be understood that the first type of signal in the first burst set is generated by a sequence, and its main functions are: providing timing synchronization and serving as a measurement resource, demodulation is simple, carries timing information, so narrow beam scanning can be used to ensure coverage. The content carried by the broadcast channel in the second burst set, except for the SSB index and the system frame number (SFN), most of the rest remains unchanged in the system information window (SI window), so wide beam scanning can be used to ensure coverage by reducing the coding rate or modulation order. Therefore, the first burst set and the second burst set are transmitted according to the above method, which can effectively reduce the number of repetitions of the broadcast channel in the air interface, so as to save the network transmission energy. Exemplarily, as shown in (a) of FIG. 1, the base station transmits the synchronization signal through a narrow beam, and as shown in (b) of FIG. 1, the base station transmits the PBCH through a wide beam. Figure 10 Figure 10

[0123] It should be noted that the beam mentioned in the embodiments of the present application can include or replace at least one of the following: beam, physical beam, logical beam, spatial filter, spatial domain filter, spatial domain transmission filter, spatial domain reception filter or antenna port.

[0124] For users in the initial access stage, the base station is implicitly informed of the beam that can be used for downlink communication by sending a preamble in the RO (RACH Occasion, random access occasion) associated with the selected SSB; for users in the connected state, the base station and the user determine the QCL (Quasi Co-Location, quasi co-location) relationship between the reference signal ports through TCI-state (Transmission Configuration Indicator-state, transmission configuration indicator-state) and / or TCI-UL-state (Transmission Configuration Indicator-Upper State, transmission configuration indicator-upper state).

For example, as shown in Figure 9B , the center frequency of the first-burst set and the second-burst set are different by 0 subcarriers, and the frequency domain resources occupied by the two are the same. It should be understood that the first-burst set and the second-burst set are aligned in the frequency domain, which can reduce the overall bandwidth occupied by the burst set, which is conducive to the design of synchronization raster.

[0154] As one embodiment, each first-burst set in the first configuration period and each second-burst set in the first configuration period are located in the same frequency domain resource.

[0220] It can be seen that the first type of candidate signal block in the present application can only include the PSS and the SSS, or only include any one of the PSS and the SSS. Compared with the SSB structure in the NR system, the first type of candidate signal block belongs to a simplified version of SSB or a lightweight version of SSB. For ease of understanding, the first type of candidate signal block will be referred to as a Lite SSB (Lite SSB) hereinafter, and the first burst set will be referred to as a Lite SSB burst set. For example, Figure 11 As shown in FIG. 2, the UE receives the first burst set and the second burst set in the first configuration period, the first burst set including the Lite SSB 0 to the Lite SSB 7, and the second burst set including the PBCH 0 to the PBCH 1.

[0221] For example, Figure 12AAs shown, the light SSB is only composed of PSS or SSS, with the starting subcarrier and symbol position of PSS as the anchor point, and SSS offsetting the starting subcarrier of PSS by Y subcarriers in the frequency domain; SSS is separated from the starting symbol of PSS by X symbols in the time domain, X is a positive integer greater than or equal to 1, and Y is a positive integer greater than or equal to 0.

[0222] As another example, PSS and SSS are respectively mapped in two adjacent OFDM symbols in the time domain, i.e. X = 1.

[0223] As another example, PSS and SSS are respectively mapped in OFDM symbols far apart in the time domain, for example X = 5.

[0224] As another example, PSS and SSS are respectively mapped on the same subcarrier in the frequency domain, i.e. Y = 0.

[0225] As another example, PSS and SSS are respectively mapped on subcarriers far apart in the frequency domain, for example Y = 12.

[0226] As another example, as shown in Figure 12B The light SSB is only composed of PSS and SSS, and PSS and SSS are aligned in the frequency domain, while SSS is separated from the starting symbol of PSS by 1 symbol in the time domain.

[0278] As an embodiment, one first type signal in at least one first type candidate signal block in the first burst set is generated based on the first sequence and at least one cyclic shift of the first sequence.

[0279] As an embodiment, X cyclic shifts of the first sequence are used to generate X first type signals in X first type candidate signal blocks in the first burst set respectively.

[0280] It should be understood that, since the synchronization signal is generated from a sequence, the first sequence refers to the sequence used to generate at least one first type signal in the first type candidate signal blocks in the first burst set.

[0281] In other words, as an embodiment, the first node can determine the second burst set corresponding to the first burst set based on the cyclic shift of the first sequence, i.e., determine the mapping relationship between the synchronization signal and the broadcast channel.

[0282] In other words, as an embodiment, the cyclic shift of the first sequence represents the index of the synchronization signal block, at this time, the time-frequency position of the broadcast channel block in at least one of the configuration period, the radio frame, the half frame, the subframe, the time slot, etc. is known information. Alternatively, the cyclic shift of the first sequence represents the index of the synchronization signal block, and at the same time, represents the time domain distance of the broadcast channel block mapped thereto, at this time, the time-frequency position of the broadcast channel block in the above time unit is known information (or carried by the broadcast channel block itself); or, the cyclic shift of the first sequence represents the time domain distance between the synchronization signal block and the beginning and end of the above time unit, at this time, the time-frequency position of the broadcast channel block in the above time unit is known information; or, the cyclic shift of the first sequence represents the time domain distance between the synchronization signal block and the broadcast channel block mapped thereto, at this time, the time-frequency position of the broadcast channel block in the above time unit is known information (or carried by the broadcast channel block itself). For example, as shown in FIG. 6, the UE detects the synchronization signal, and determines the position of the current synchronization signal through the cyclic shift of the synchronization signal. Figure 13 ​

[0283] As an embodiment, the second node can generate one first type signal in the ith first type candidate signal block based on a frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain, i is a positive integer, 1≤i≤X; the frequency domain offset is a number of subcarriers that the first primary synchronization signal and the first secondary synchronization signal offset in frequency domain.

[0284] In an embodiment, the frequency domain offset of the first primary synchronization signal in frequency domain and the frequency domain offset of the first secondary synchronization signal in frequency domain are used to determine that one first burst set is determined from a plurality of first burst sets; In an embodiment, the frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain is used to determine an index of one first burst set in a plurality of first burst sets; In an embodiment, the frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain is used to determine a time domain position of one first burst set; In an embodiment, the frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain is used to determine a frequency domain position of one first burst set; In an embodiment, the frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain is used to determine a time domain interval between one second burst set and one first burst set; In an embodiment, the frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain is used to determine that the ith first type candidate signal block is determined from X first type candidate signal blocks included in the first burst set; In an embodiment, the frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain is used to determine an index of the ith first type candidate signal block in the X first type candidate signal blocks in the first burst set; In an embodiment, the frequency domain offset of the first primary synchronization signal and the first secondary synchronization signal in frequency domain is used to determine a time domain interval between the ith first type candidate signal block in the first burst set and the jth second type candidate signal block in the second burst set, j is a positive integer, 1≤j≤Y.

[0285] For example, Figure 14As shown, the first primary synchronization signal and the first secondary synchronization signal are two first-type signals in the first-type candidate signal block in the first burst set; and the frequency domain offset is a number Y of subcarriers by which the first primary synchronization signal and the first secondary synchronization signal are offset in the frequency domain. Based on the number Y of subcarriers by which the SSS is offset upward in the frequency domain with respect to the PSS, the UE determines a second burst set corresponding to the first burst set, i.e., determines the mapping relationship between the synchronization signal and the broadcast channel.

[0286] As an embodiment, the number of subcarriers of the frequency domain offset represents an index of the synchronization signal block, in which case the time-frequency position of the broadcast channel block in at least one of a configuration period, a radio frame, a half frame, a subframe, a time slot, etc. is known information; or the number of subcarriers of the frequency domain offset represents an index of the synchronization signal block and at the same time represents a time domain distance of the broadcast channel block to which it is mapped, in which case the time-frequency position of the broadcast channel block in the above-mentioned time unit is known information (or is carried by the broadcast channel block itself); or the number of subcarriers of the frequency domain offset represents a time domain distance of the synchronization signal block to the beginning / end of the above-mentioned time unit, in which case the time-frequency position of the broadcast channel block in the above-mentioned time unit is known information; or the number of subcarriers of the frequency domain offset represents a time domain distance of the synchronization signal block to the broadcast channel block to which it is mapped, in which case the time-frequency position of the broadcast channel block in the above-mentioned time unit is known information (or is carried by the broadcast channel block itself).

[0287] As an embodiment, the first node does not need to determine the mapping relationship between the synchronization signal and the broadcast channel through the information in the first burst set. In other words, the protocol stipulates that the time interval between the synchronization signal block and the broadcast channel is fixed, for example, as shown in Figure 15 In this way, after the first node detects the synchronization signal, it searches for the broadcast channel within a fixed range according to the time domain position of the synchronization signal. The fixed range in this embodiment can be at least one of a time slot, a subframe, a half frame, a system frame, or a synchronization block configuration period, so that after the broadcast channel is searched, the index of the synchronization signal is determined according to the time offset between the synchronization signal and the broadcast channel.

[0288] In some embodiments, the first node performs a first operation based on the first burst set, and the first operation includes at least one of broadcast channel detection, time-frequency synchronization, signal measurement, and measurement result reporting.

[0289] In order to more systematically elaborate on the above-mentioned method embodiments, the above-mentioned method will be described by way of example in combination with a specific scene example as shown in Figures 16-17

[0290] Figure 16 The method flow as shown includes steps S1615 to S1620.

[0291] ​S1615, the base station sends the first burst set and the second burst set to the UE.

[0292] The description about the first burst set and the second burst set can refer to the above embodiments.

[0293] S1620, the UE detects the first burst set and the second burst set and performs synchronization.

[0294] In this embodiment, the first burst set and the second burst set are used for initial synchronization, the UE searches the synchronization block at the specified position, which is each BWP in the service cell of the base station. The UE detects the synchronization signal and obtains the cell ID. When the synchronization signal block in the first burst set carries the cyclic shift or the frequency domain offset, the UE determines the mapping relationship between the synchronization signal and the broadcast channel based on the cyclic shift or the frequency domain offset; when the synchronization signal block in the first burst set does not carry the cyclic shift or the frequency domain offset, the UE determines the mapping relationship between the synchronization signal and the broadcast channel according to the protocol agreement. Then, the UE can detect the broadcast channel according to the mapping relationship between the synchronization signal and the broadcast channel, and perform subsequent processes such as cell search / reselection / access, etc.

[0295] Optionally, when the first burst set and the second burst set are not used for initial synchronization, the above embodiment can further include step S1610, the UE receives the first configuration information from the base station. The first configuration information can be carried in RRC signaling, MAC signaling or DCI signaling. At this time, S1620 can be replaced by: detecting the first burst set and the second burst set based on the first configuration information and performing synchronization. That is, the UE receives the detection synchronization signal block at the time-frequency position indicated by the first configuration information, and completes the downlink synchronization.

[0296] Figure 17 The method flowchart shown includes steps S1710 to S1725.

[0297] S1710, the UE receives the first configuration information from the base station.

[0298] S1715, the base station sends the first burst set and the second burst set to the UE.

[0299] S1720, the UE receives and detects the on-demand SSB burst set based on the position specified by the first configuration information, and obtains the measurement result.

[0300] For example, the measurement result can be the average of multiple measurement results of multiple light SSBs in one light SSB burst set, or the maximum of multiple measurement results of multiple light SSBs in one light SSB burst set, or the average of multiple measurement results of one light SSB in multiple light SSB burst sets.

[0301] S1725, the UE reports the measurement result. Exemplarily, in one possible case, the UE acquires measurement values of at least one SSS, performs linear averaging, generates a measurement report, and reports the same, the measurement values can be RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), and SINR (Signal to Interference plus Noise Ratio); in another possible case, the UE acquires measurement values of at least one PSS, performs linear averaging, generates a measurement report, and reports the same, the measurement values can be RSRP, RSRQ, and SINR; in still another possible case, the UE acquires measurement values of at least one DMRS of PBCH, performs linear averaging, generates a measurement report, and reports the same, the measurement values can be RSRP, RSRQ, and SINR.

The multiple antenna transmit processor 2171 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding, and beamforming processing, generating one or more spatial streams. The transmit processor 2116 then maps each spatial stream to a subcarrier, multiplexes the stream with reference signals (e.g., pilot), and then performs an inverse fast Fourier transform to generate a time-domain multicarrier symbol stream. The multiple antenna transmit processor 2171 then performs transmit analog pre-coding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 2118 converts a baseband multicarrier symbol stream provided by the multiple antenna transmit processor 2171 into a radio frequency stream, and then provides the radio frequency stream to a different antenna 2120.

The transmit processor 2168 performs modulation mapping, channel coding processing, multi-antenna transmit processor 2157 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, and then the transmit processor 2168 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, which are provided to different antennas 2152 via the transmitters 2154 after analog precoding / beamforming operation in the multi-antenna transmit processor 2157. Each transmitter 2154 first converts the baseband symbol stream provided by the multi-antenna transmit processor 2157 into a radio frequency signal, and then provides the radio frequency signal to the antenna 2152.
