Description

Communication methods and devices

[0001] This application claims priority to Chinese Patent Application No. 202510112515.9, filed on January 22, 2025, entitled "Communication Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication, and more particularly to communication methods and apparatus. Background Technology

[0003] As communication systems evolve, base stations and terminals will face challenges from greater bandwidth, faster processing speeds, and more antennas. Power consumption is one such challenge. For base stations, increased power consumption means higher operating costs; for terminals, it means more power is required. However, for terminals, the size and area of ​​batteries are limited by various factors. Furthermore, increased power consumption also brings other problems such as heat dissipation.

[0004] Currently, the power consumption of 5G mobile communication systems is about three times that of 4G systems, leading to serious heat dissipation problems and a poor user experience. Therefore, addressing the power consumption issue of communication systems is a crucial consideration. Summary of the Invention

[0005] This application provides a communication method and apparatus that uses frequency division multiplexing to perform different signals in a signal block on any one symbol, allowing signals originally distributed across different symbols to be transmitted on the same symbol. This means that symbols that were originally used separately for each signal are now idle, allowing the terminal to be configured to sleep or used to transmit other signals. This allows the terminal to configure sleep on the time slots originally occupied by other signals, thereby increasing the time-domain locations where the terminal can sleep and reducing its power consumption.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] Firstly, a communication method is provided, applied to a first device, which may be a terminal, a component of the terminal (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the terminal's functions. The method may include: receiving a first signal block. For example, the first signal block may include a first signal and a second signal. For example, the first signal may include a primary synchronization signal (PSS) and / or a secondary synchronization signal (SSS). For another example, the second signal may include a physical broadcast channel (PBCH). The first signal block is carried on at least one symbol. For example, the first signal and the second signal may be frequency-division multiplexed on any one of the at least one symbols. Communication is performed based on the first signal block. For example, synchronization may be performed based on the first signal block.

[0008] This application allows different signals in a signal block to be frequency-division multiplexed on any one symbol, enabling signals originally distributed across different symbols to be transmitted on the same symbol. This means that symbols that were originally used separately for each signal are now idle, allowing the terminal to be configured to sleep or used to transmit other signals. This allows the terminal to configure sleep on the time slots originally occupied by other signals, thereby increasing the time-domain locations where the terminal can sleep and reducing its power consumption.

[0009] In one possible design, for any symbol carrying the first signal block, the first signal can occupy a first number of first frequency domain resources, such as N. The second signal can occupy a second number of second frequency domain resources, such as M. N and M can be positive integers. A third number of first frequency domain resources can be located at one or both ends of a fourth number of second frequency domain resources. One possibility is that consecutive third number of first frequency domain resources can be located at one or both ends of consecutive fourth number of second frequency domain resources. For example, if the third number is P, these P first frequency domain resources can belong to N first frequency domain resources. The fourth number can be S, and these S second frequency domain resources can belong to M second frequency domain resources.

[0010] This application provides a specific form of frequency domain allocation for signal blocks, which enables signal blocks composed in this way to occupy as few symbols as possible while transmitting the corresponding signals, thereby increasing the time domain positions where the terminal can sleep and reducing the terminal power consumption.

[0011] In one possible design, the PSS and / or SSS in the first signal can be used for demodulation of the second signal. For example, the PSS and / or SSS can be used for demodulation of the PBCH.

[0012] In this application, the first signal, including PSS and SSS, can also be used to demodulate the second signal. When the second signal still includes DMRS, more accurate channel estimation can be achieved, and universality can be improved. When the second signal does not include DMRS, the data transmission efficiency of the second signal can be improved.

[0013] In one possible design, for any symbol carrying the first signal block, the first signal can occupy a first number of first frequency domain resources, such as N. The second signal can occupy a second number of second frequency domain resources, such as M. N and M can be positive integers. A third number of first frequency domain resources can be located at one or both ends of the M second frequency domain resources. One possibility is that a consecutive third number of first frequency domain resources can be located at one or both ends of the M second frequency domain resources. For example, if the third number is P, these P first frequency domain resources can belong to N first frequency domain resources.

[0014] This application provides a specific form of frequency domain allocation for signal blocks, which enables signal blocks composed in this way to occupy as few symbols as possible while transmitting the corresponding signals, thereby increasing the time domain positions where the terminal can sleep and reducing the terminal power consumption.

[0015] In one possible design, the number of symbols occupied by the first signal block can be less than or equal to 3.

[0016] The first signal block of this application can occupy three or even fewer symbols. Compared with the traditional synchronization signal and physical broadcast channel block (SS / PBCH block or SSB), it can free up more time domain resources so that the terminal can go to sleep and reduce the power consumption of the terminal.

[0017] In one possible design, the symbols occupied by the first signal block may include a first symbol and a second symbol. For example, the first signal carried on the first symbol may include a PSS, and the first signal carried on the second symbol may include an SSS.

[0018] This application isolates the PSS and SSS using time division, while also multiplexing the symbols with the second signal using frequency division. This improves the management efficiency of the first signal and frees up more time-domain resources for the terminal to enter sleep mode, reducing terminal power consumption.

[0019] In one possible design, the first signal block can be used for at least one of the following communication functions: initial access; channel state measurement; paging; service communication; or, sensing.

[0029] In one possible design, the method may further include receiving a second signal block. This second signal block can be used to indicate the first cycle and / or the second cycle.

[0031] In one possible design, the first signal block can be configured with multiple resource patterns. For example, the resource patterns can be uniform resource patterns. Alternatively, the resource patterns can be non-uniform resource patterns.

This allows for the appropriate mapping of the first signal block in different communication scenarios, improving system versatility.

[0219] Figure 1 is a schematic diagram of the architecture of a communication system 1000 provided in an embodiment of this application. As shown in Figure 1, the communication system 1000 includes a radio access network (RAN) 100, wherein the RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110), and may also include at least one terminal (120a-120j in Figure 1, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). The terminal 120 is wirelessly connected to the RAN node 110. Terminals and RAN nodes can be interconnected via wired or wireless means. The communication system 1000 may also include a core network 200. The RAN node 110 is connected to the core network 200 via wireless or wired means. The core network equipment in core network 200 and the RAN node 110 in RAN 100 can be independent and different physical devices, or they can be the same physical device that integrates the logical functions of the core network equipment and the logical functions of the RAN node. Communication system 1000 may also include Internet 300.

[0220] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, a future communications network, or a future radio access system as defined in the 3rd generation partnership project (3GPP). RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0221] RAN nodes, also known as radio access network devices, RAN entities, or access nodes, are used to help terminals access communication systems wirelessly. In one application scenario, an RAN node can be a base station (BS), an evolved NodeB (eNodeB / eNB), a transmission reception point (TRP), a generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a future base station in a future communication network, or a base station in a future mobile communication system. RAN nodes can be macro base stations (as shown in Figure 1, 110a), micro base stations or indoor stations (as shown in Figure 1, 110b), relay nodes, or master nodes.

[0222] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). An RU can also be called a radio frequency unit. Here, the CU performs the functions of the base station's radio resource control protocol and packet data convergence protocol (PDCP), and can also perform the functions of the service data adaptation protocol (SDAP). The DU performs the functions of the base station's radio link control layer and medium access control (MAC) layer, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as within a baseband unit (BBU). RUs can be included in radio frequency equipment, such as remote radio units (RRUs) or active antenna units (AAUs). CUs can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0223] In different systems, RAN nodes may have different names. For example, in an open radio access network (O-RAN) system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, an RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes. For ease of description, a base station is used as an example of a RAN node in the following description.

[0224] A terminal is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminals can also be called terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal. A terminal can also be a chip containing modulation and demodulation functions (e.g., a baseband chip), a system-on-chip (SoC) containing a modem module, or a system-in-package (SIP) chip.

[0225] In some examples, the core network 200 may include any core network device such as the access and mobility management function (AMF) entity, the session management function (SMF) entity, the user plane function (UPF) entity, the sensing service control function (SSCF), the sensing data processing function (SDPF), and the unified data management (UDM).

[0226] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0227] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. For terminals 120j that access the wireless access network 100 through 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol. In this case, relative to 110a, 120i is also a base station. Therefore, both base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with base station functions, and 120a-120j in Figure 1 can be called communication devices with terminal functions.

[0228] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0229] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0230] In a wireless communication system, communication devices are included, and these devices can communicate wirelessly using air interface resources. These communication devices can include network devices and terminal devices; network devices can also be called base station devices, i.e., the wireless access network devices mentioned above. Air interface resources can include at least one of time-domain resources, frequency-domain resources, code resources, and spatial resources. These communication devices can also be called communication apparatuses.

[0231] The solutions provided in this application can be applied to wireless communication between communication devices. Wireless communication can include: wireless communication between network devices and terminals, wireless communication between network devices, and wireless communication between terminals. In this application, the term "wireless communication" can also be simply referred to as "communication," and the term "communication" can also be described as "data transmission," "information transmission," or "transmission."

[0232] Currently, in the initial protocol version, 5G terminals consume approximately three times the power of fourth-generation (4G) mobile communication systems, resulting in severe heat dissipation issues and a poor user experience. With the evolution of the 3rd Generation Partnership Project (3GPP), each version has standardized terminal power-saving features. Furthermore, joint optimization with the network can further control terminal power consumption. However, despite the standardization of some terminal power-saving features, various factors, such as increased operator costs, declining network key performance indicators (KPIs), and uncertain market prospects, have prevented most of these features from being commercially deployed. Therefore, it is clear that 5G has not effectively solved the power consumption problem.

[0233] According to recommendations from the International Telecommunication Union (ITU), the scenarios and requirements for future mobile communication systems are likely to be more complex than those for 5G. As shown in Table 1, future mobile communication systems may have higher performance requirements than 5G.

[0234] Table 1

[0235] It is evident that there is significant growth potential across various metrics in future mobile communication scenarios. Consequently, terminals and network devices will face greater challenges in these future environments. For instance, the most direct consequence of this increased demand is a potential increase in device power consumption, clearly a major challenge for future mobile communication scenarios.

[0236] Compared to 5G, future mobile communication scenarios may take into account issues such as future energy shortages and the environment. Therefore, sustainability can be considered one of the inherent requirements of this mobile communication scenario.

[0237] For current 5G, some measurement characteristics have been standardized. For example, radio resource management (RRM) measurements, radio link monitoring (RLM) measurements, and beam failure recovery (BFR) measurements may involve synchronization signals and physical broadcast channel blocks (SS / PBCH blocks or SSB) and / or channel state information-reference signals (CSI-RS); for example, channel state information (CSI) measurements may involve CSI-RS; for example, beam measurements may involve SSB and / or CSI-RS; or, time-frequency synchronization / time-frequency offset estimation may involve SSB and / or tracking reference signals (TRS); or, initial access measurements may involve SSB.

[0238] The aforementioned measurements may be scattered across different times and may be reported periodically, semi-persistently, or aperiodically. Correspondingly, the measurement resources and whether reporting occurs can depend on the network device configuration and instructions. Because network device configuration is quite flexible, different measurement resources may be configured, and reporting resources may be scattered across different locations, causing terminals to be unable to sleep and to continuously wake up for measurement purposes.

[0239] Referring to Figure 2, for example, four different signals are used for different measurement scenarios, and these different signals are allocated to different resources in the time domain. In Figure 2, the white boxes represent the time domain resource locations configured for the corresponding signals. Measurement scenarios can include any of the aforementioned measurements, or any other possible measurement scenarios; this embodiment does not limit the scope. For a terminal, sleep mode is only possible if no measurement is configured on a certain time domain resource. Clearly, in the case shown in Figure 2, the terminal's sleep time is very limited. For example, the terminal may have sleep conditions, such as triggering sleep mode when it does not need to receive signals (or measure signals) for a certain duration. Therefore, there may even be situations where the terminal cannot trigger sleep mode at all.

[0240] In initial access and measurement scenarios in 5G, SSB (Special Support Bus) may be involved. For NR (Normally Infrared) deployments at high frequencies, network equipment typically uses massive MIMO (Multiple-Input Multiple-Output) antennas to enhance coverage. However, massive MIMO antennas result in very narrow beamwidths, making it difficult for a single beam to cover the entire cell. Furthermore, due to hardware limitations, network equipment usually cannot simultaneously transmit multiple beams to cover the entire cell. Some solutions propose beam sweeping to cover the entire cell. For example, the network equipment transmits one or several beam directions at a certain time, covering the required directions for the entire cell by transmitting different beams at multiple times.

[0241] For each of the aforementioned beams, a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) can be configured. The PBCH may include a demodulation reference signal (DMRS) to enable downlink synchronization by the terminal. In NR, the PSS, SSS, PBCH, and the DMRS of the PBCH can be bundled and transmitted simultaneously, i.e., the aforementioned SSB. The beam transmitting the SSB can be called the SSB beam.

[0242] For example, PSS can also be called the primary synchronization sequence. For instance, when a terminal powers on and enters the NR system, it can search for the PSS. During this phase, the terminal can search for cells on a given (or default) carrier frequency. If the terminal detects a PSS, it can synchronize to the PSS number period.

[0243] For example, SSS can also serve as a secondary synchronization sequence. For instance, when a terminal detects PSS, it can determine the timing of SSS transmission. By detecting SSS, the terminal can determine the cell's PCI.

[0244] For example, the PBCH can carry the master information block (MIB), also known as the master system information block. This MIB may include information such as the system frame number (SFN), cell block identifier, and system information block (SIB) parameter set. Terminals can use this information to obtain other system information broadcast via the network.

[0245] For example, DMRS in PBCH can be used for terminal demodulation of PBCH.

[0246] As can be seen, the SSB can serve two purposes: one is for cell search, and the other is as a reference signal for cell measurement within the terminal. By measuring the SSB, the terminal can report the layer (L1) reference signal receiving power (RSRP) and the SSB resource indicator (RI). For example, the L1-RSRP can be used in mobility management processes such as cell selection, cell reselection, and cell handover, while the SSBRI can be used for initial beam management.

[0247] To gain a deeper understanding of SSB, the time-frequency structure of SSB will be described in detail below.

[0248] In the time domain, an SSB can consist of four consecutive orthogonal frequency division multiplexing (OFDM) symbols. For example, the OFDM symbols in an SSB can be numbered from 0 to 3 in ascending order. In the frequency domain, an SSB can consist of 240 consecutive subcarriers, or it can be considered as consisting of 20 consecutive resource blocks (RBs). For example, an RB can include 12 resource elements (REs), and one RE corresponds to one subcarrier in the frequency domain. In the various embodiments of this application, OFDM symbols can also be referred to as symbols, orthogonal frequency division multiple access (OFDMA) symbols, etc., and the embodiments of this application are not limited to these terms.

[0249] Referring to Figure 3, a structure of an SSB is shown. It can be seen that the PSS occupies the first symbol (symbol 0) of the SSB in the time domain, and the SSS occupies the third symbol (symbol 2) of the SSB in the time domain; and the PSS and SSS occupy 127 subcarriers in the frequency domain, i.e., carriers 56 to 182. The PBCH can completely occupy the second symbol (symbol 1) and the fourth symbol (symbol 3) of the SSB, as well as part of the subcarriers of the third symbol (symbol 2), such as 48 subcarriers at each end of the third symbol (symbol 2), i.e., carriers 0 to 47, and carriers 192 to 239. The PBCH occupies a total of 576 subcarriers (or REs). Excluding the DMRS, the number of subcarriers (or REs) used for data transmission in the PBCH can be 432.

[0250] Of course, the PBCH mentioned above includes the time-frequency resources occupied by the DMRS. For example, the way the DMRS occupies resources in the PBCH can be seen in Figure 4, where different values ​​of v represent different mapping methods for the DMRS. For example, it can include four different DMRS mapping methods, distinguished by different values ​​of v.

[0251] In some examples, the SSB transmission period can be configured to 5ms, 10ms, 20ms, 40ms, 80ms, and 160ms, for example, indicated by the higher-layer parameter ssb-periodicityServingCell. When the terminal performs an initial cell search, or performs a cell search in idle mode or during movement, the terminal can assume an SSB transmission period of 20ms. In this way, the terminal knows the time required to search for an SSB on a certain frequency. If the UE does not find a PSS and / or SSS within this time, the terminal can switch to the next frequency of the synchronization grid to continue the search.

[0252] Network devices can transmit SSBs using beam scanning, such as transmitting SSBs across different beams via time-division multiplexing. The set of SSBs within a beam scan can be called an SSB burst set. It can be understood that the transmission period of the SSBs mentioned above (or simply the SSB period) is the transmission period of the SSB burst set (or simply the SSB burst set period). Within each SSB period, the SSB burst set is generally limited to a time interval of 5ms, for example, it can be within the first half of a frame or the second half of a frame. Figure 5 illustrates the allocation of SSB burst sets in the time domain. Assume an SSB burst set includes x SSBs, the first SSB is called SSB#0, the second SSB is called SSB#1, and so on up to the xth SSB, which is called SSB#x-1, where x can be a positive integer. Each SSB is transmitted through one beam. It can be seen that, assuming the period of the SSB burst set is 20ms, the x SSBs are transmitted within 5ms of that 20ms.

[0253] The maximum number of SSBs within an SSB burst set can vary depending on the frequency band, for example, it can vary depending on the SSB sub-carrier spacing (SCS). Table 2 shows the possible correspondence between SSB sub-carrier spacing and frequency range (FR).

[0254] Table 2

[0255] It can be seen that the larger the SCS of an SSB, the larger its bandwidth. At the same time, a larger SCS leads to a shorter OFDM duration, and consequently, a shorter duration for a single SSB.

[0256] The possible locations of SSBs within each SSB burst set (with a duration of half a frame) can be called an SSB pattern. Each SSB in this SSB pattern can also be called a candidate SSB.

[0257] The following sections will introduce several different SSB patterns.

[0258] Case A:

[0259] The SCS can be 15kHz. The index of the first symbol of a candidate SSB in its half-frame can be {2,8}+14×n′, as shown in Figure 6. Assuming the carrier frequency is less than or equal to 3GHz, n′ can be 0 or 1. Correspondingly, the candidate SSB can be located on subframe 0 (i.e., the first subframe) or subframe 1 (i.e., the second subframe) of a half-frame. The first symbol of the candidate SSB can be located on OFDM symbol 2 (i.e., the third OFDM symbol) or OFDM symbol 8 (i.e., the ninth OFDM symbol) of these subframes. Therefore, a maximum of 4 SSBs can be transmitted within each half-frame, which can be denoted as Lmax = 4.

[0260] Assuming the carrier frequency is FR1 and greater than 3 GHz, n′ can be equal to 0, 1, 2, or 3. Correspondingly, candidate SSBs can be located on subframe 0 (i.e., the first subframe), subframe 1 (i.e., the second subframe), subframe 2 (i.e., the third subframe), and subframe 3 (i.e., the fourth subframe) of a half-frame. The first symbol of a candidate SSB can be located on OFDM symbol 2 (i.e., the third OFDM symbol) or OFDM symbol 8 (i.e., the ninth OFDM symbol) of these subframes. Therefore, a maximum of 8 SSBs can be transmitted within each half-frame, denoted as Lmax = 8.

[0261] Observation reveals that OFDM symbols 0, 1, 6, 7, 12, and 13 in the time slot where the candidate SSB is located in case A are not used for the SSB. This is mainly due to considerations of communication between the physical downlink control channel (PDCCH) and the physical uplink control channel (PUCCH), as well as the coexistence of data and control channels with SCS = 30kHz.

[0262] For example, OFDM symbols 0 and 1 can be used to transmit PDCCH, and OFDM symbols 12 and 13 can be used to transmit PUCCH. When the SCS is the same, for any SCS, the first and last two OFDM symbols of each time slot must be reserved for transmitting PDCCH and PUCCH.

[0263] Referring to Figure 7, for different SCS values, OFDM symbol 6 with SCS = 15kHz can correspond to OFDM symbols 12 and 13 with SCS = 30kHz; OFDM symbol 7 with SCS = 15kHz can correspond to OFDM symbols 0 and 1 with SCS = 30kHz. As mentioned above, OFDM symbols 12 and 13 with SCS = 30kHz can transmit PUCCH, while OFDM symbols 0 and 1 can transmit PDCCH. Therefore, to reduce the impact of the SSB with SCS = 15kHz on the data and control channels with SCS = 30kHz, OFDM symbols 6 and 7 with SCS = 15kHz need to be reserved.

[0264] Situation B:

[0265] The SCS can be 30kHz. The index of the first symbol of a candidate SSB in its half-frame can be {4,8,16,20}+28×n′, as shown in Figure 8. Assuming the carrier frequency is less than or equal to 3GHz, n′ can be 0. The first symbol of a candidate SSB can be located on OFDM symbol 4 (the 5th OFDM symbol), OFDM symbol 8 (the 9th OFDM symbol), OFDM symbol 16 (the 17th OFDM symbol), or OFDM symbol 20 (the 21st OFDM symbol) in subframe 0 (the 1st subframe) of a half-frame. Therefore, a maximum of 4 SSBs can be transmitted within each half-frame, denoted as L. max =4.

[0266] Assuming the carrier frequency is FR1 and greater than 3 GHz, n′ can be equal to 0 or 1. Accordingly, candidate SSBs can be located on subframe 0 (i.e., the first subframe) or subframe 1 (i.e., the second subframe) of a half-frame. The first symbol of a candidate SSB can be located on OFDM symbol 4 (i.e., the fifth OFDM symbol), OFDM symbol 8 (i.e., the ninth OFDM symbol), OFDM symbol 16 (i.e., the seventeenth OFDM symbol), or OFDM symbol 20 (i.e., the twenty-first OFDM symbol) of these subframes. Therefore, a maximum of 8 SSBs can be transmitted within each half-frame, denoted as L. max =8.

[0267] Observation reveals that in Case B, the first four OFDM symbols and the last two OFDM symbols of the first time slot in subframes 0 and 1, and the first two OFDM symbols and the last four OFDM symbols of the second time slot, are not used for SSB transmission. This is primarily due to considerations for PDCCH and PUCCH communication, as well as the coexistence of data and control channels with SCS = 15kHz. Referring to Figure 7, for example, the first four OFDM symbols of time slot 2y with SCS = 30kHz correspond to the first two OFDM symbols of time slot y with SCS = 15kHz; these two OFDM symbols can be used to transmit PDCCH. Similarly, the last four OFDM symbols of time slot 2y+1 with SCS = 30kHz correspond to the last two OFDM symbols of time slot y with SCS = 15kHz; these two OFDM symbols can be used to transmit PUCCH. To ensure the coexistence of data and control signals with SCS = 30kHz and SCS = 15kHz, these OFDM symbols are not used for SSB transmission.

[0268] Case C:

[0269] The SCS can be 30kHz. The index of the first symbol of the candidate SSB in its half-frame can be {2,8}+14×n′, as shown in Figure 9. Similar to Figure 6, the difference is that in Figure 6, one subframe corresponds to one time slot, while in Figure 9, one subframe corresponds to two time slots.

[0270] For frequency division duplex (FDD):

[0271] Assuming the carrier frequency is less than or equal to 3 GHz, n′ can be 0 or 1. The first symbol of a candidate SSB can be located on OFDM symbol 2 (the 3rd OFDM symbol) or OFDM symbol 8 (the 9th OFDM symbol) in each time slot of subframe 0 (the 1st subframe) of a half-frame. If the OFDM symbols are numbered sequentially within two time slots, they can also be considered to be on OFDM symbols 2 (the 3rd OFDM symbol), 8 (the 9th OFDM symbol), 16 (the 17th OFDM symbol), and 20 (the 21st OFDM symbol) in subframe 0 (the 1st subframe). Therefore, a maximum of 4 SSBs can be transmitted within each half-frame, denoted as L. max =4.

[0272] Assuming the carrier frequency is FR1 and greater than 3 GHz, n′ can be equal to 0, 1, 2, or 3. Correspondingly, candidate SSBs can be located on subframe 0 (i.e., the first subframe) or subframe 1 (i.e., the second subframe) of a half-frame. The first symbol of a candidate SSB can be located on OFDM symbol 2 (i.e., the third OFDM symbol) or OFDM symbol 8 (i.e., the ninth OFDM symbol) in each time slot of these subframes. Alternatively, if numbered sequentially by two time slot OFDM symbols, they can also be considered as OFDM symbol 2 (i.e., the third OFDM symbol), OFDM symbol 8 (i.e., the ninth OFDM symbol), OFDM symbol 16 (i.e., the seventeenth OFDM symbol), or OFDM symbol 20 (i.e., the twenty-first OFDM symbol) in these subframes. Therefore, a maximum of 8 SSBs can be transmitted within each half-frame, denoted as L. max =8.

[0273] For Time Division Duplex (TDD):

[0274] Assuming the carrier frequency is less than or equal to 2.4 GHz, n′ can be equal to 0 or 1. The configuration of candidate SSBs is similar to that in FDD when the carrier frequency is less than or equal to 3 GHz, and will not be described again in the embodiments of this application.

[0275] Assuming the carrier frequency is FR1 and greater than 2.4 GHz, n′ can be equal to 0, 1, 2, or 3. The configuration of candidate SSBs is similar to that in FDD when the carrier frequency is greater than 3 GHz, and will not be described again in the embodiments of this application.

[0276] Observation reveals that in case C, although the candidate SSB has OFDM symbols 0 (i.e., the first OFDM symbol), 1 (i.e., the second OFDM symbol), 6 (i.e., the seventh OFDM symbol), 7 (i.e., the eighth OFDM symbol), 12 (i.e., the thirteenth OFDM symbol), and 13 (i.e., the fourteenth OFDM symbol) in the time slot, these symbols are not used for the SSB. This is mainly due to considerations for PDCCH and PUCCH communication, as well as the coexistence of data and control channels with SCS = 60kHz. For example, OFDM symbol 6 (i.e., the seventh OFDM symbol) with SCS = 30kHz can correspond to OFDM symbols 12 (i.e., the thirteenth OFDM symbol) and 13 (i.e., the fourteenth OFDM symbol) with SCS = 60kHz. For example, OFDM symbol 7 (i.e., the 8th OFDM symbol) with SCS = 30kHz can correspond to OFDM symbol 0 (i.e., the 1st OFDM symbol) and OFDM symbol 1 (i.e., the 2nd OFDM symbol) with SCS = 60kHz. Similar to the situation shown in Figure 7, the difference lies in the change of subcarrier spacing.

[0277] Situation D:

[0278] The SCS can be 120kHz. The index of the first symbol of a candidate SSB in its half-frame can be {4,8,16,20}+28×n′, as shown in Figure 10. Assuming the carrier frequency is FR2, n′ can be equal to 0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18. Candidate SSBs can be located on subframe 0 (i.e., the first subframe), subframe 1 (i.e., the second subframe), subframe 2 (i.e., the third subframe), subframe 3 (i.e., the fourth subframe), and subframe 4 (i.e., the fifth subframe) of a half-frame. A maximum of 64 SSBs can be transmitted within each half-frame, which can be denoted as L. max =64.

[0279] Observation reveals that, similar to case B, in case D, the first four OFDM symbols and the last two OFDM symbols in even-numbered time slots (such as the first and third time slots), and the first two OFDM symbols and the last four OFDM symbols in odd-numbered time slots (such as the second and fourth time slots), are not used for the SSB. This is mainly due to considerations for the communication of PDCCH and PUCCH, as well as the coexistence issue with the data and control channels at SCS = 60kHz. For details, please refer to the coexistence problem described in Figure 7; the embodiments in this application will not elaborate further.

[0280] Situation E:

[0281] The SCS can be 240kHz. The index of the first symbol of a candidate SSB in its half-frame can be {8,12,16,20,32,36,40,44}+56×n′, as shown in Figure 11. Specific descriptions of candidate SSB positions can be found in cases A to D, differing only in the symbol indices, which will not be repeated in this embodiment. It can be observed that in case E, the first 8 OFDM symbols and the last 8 OFDM symbols of each time slot group are not used for SSBs. In the case of SCS = 240kHz, each time slot group can include 4 time slots. This is mainly to address the coexistence issue with data and control channels with SCS = 60kHz. For example, the first 8 OFDM symbols of each time slot group with SCS = 240kHz correspond to OFDM symbol 0 (i.e., the first OFDM symbol) and OFDM symbol 1 (i.e., the second OFDM symbol) with SCS = 60kHz; and the last 8 OFDM symbols of each time slot group with SCS = 240kHz correspond to OFDM symbol 12 (i.e., the 13th OFDM symbol) and OFDM symbol 13 (i.e., the 14th OFDM symbol) with SCS = 60kHz, as shown in Figure 12.

[0282] For the case of SCS = 240kHz, the first four OFDM symbols of even-numbered time slots in each time slot group, and the last four OFDM symbols of odd-numbered time slots, are not used for the SSB. This is mainly to address the coexistence issue with the data and control channels at SCS = 120kHz. Referring to Figure 12, for example, the first four OFDM symbols of even-numbered time slots in each time slot group of SCS = 240kHz can correspond to OFDM symbol 0 (i.e., the first OFDM symbol) and OFDM symbol 1 (i.e., the second OFDM symbol) at SCS = 120kHz; and the last four OFDM symbols of odd-numbered time slots in each time slot group of SCS = 240kHz can correspond to OFDM symbol 12 (i.e., the thirteenth OFDM symbol) and OFDM symbol 13 (i.e., the fourteenth OFDM symbol) at SCS = 120kHz.

[0283] Of course, for the various possible SSB patterns, more specific configuration methods can be found in relevant technologies, which will not be elaborated upon in the embodiments of this application.

[0284] As can be seen from the SSB patterns under the different scenarios described above, excessive time-domain symbol usage in SSBs reduces the time-domain sleep time of the terminal. Referring to Figure 13, assuming the remaining time-domain resources are unused, approximately 30% of the symbols are still used for SSB transmission within a single SSB cycle. Clearly, increasing the duration of terminal sleep time and reducing the time-domain space occupied by corresponding signals are problems that need to be addressed.

[0285] Therefore, this application provides a communication method that uses frequency division multiplexing to perform different signals in a signal block on any one symbol, allowing signals originally distributed across different symbols to be transmitted on the same symbol. This means that the symbols that were originally used separately for each signal are now idle, allowing the terminal to be configured to sleep or used to transmit other signals. This allows the terminal to configure sleep on the time slots originally occupied by other signals, thereby increasing the time-domain locations where the terminal can sleep and reducing its power consumption.

[0286] The communication method and apparatus will be further described below with reference to the accompanying drawings. It is understood that the embodiments of this application use a terminal and a network device as examples to illustrate the execution of the interaction, but this application does not limit the execution subject of the interaction. The method executed by the terminal in this application can also be implemented by modules in the terminal (e.g., circuits, processors, chips, or chip systems), or by logical nodes, logical modules, or software that can implement all or part of the terminal's functions. Similarly, the method executed by the network device in this application can also be implemented by modules in the network device (e.g., circuits, processors, chips, or chip systems), or by logical nodes, logical modules, or software that can implement all or part of the network device's functions.

[0287] Figure 14 is a schematic diagram of a communication scenario provided by an embodiment of this application.

[0288] The embodiments of this application can also be applied to O-RAN network architecture. Therefore, Figure 14 illustrates a scenario under the O-RAN architecture. In the O-RAN architecture, access network devices can be divided into three functional entities: O-RU, O-DU, and O-CU. The O-RU is similar to the aforementioned RU, the O-DU is similar to the aforementioned DU, and the O-CU is similar to the aforementioned CU. The interfaces between these functional entities can be referred to the descriptions in the previous embodiments, and will not be repeated here. The O-RAN network architecture may also include a near-real-time RAN intelligent controller (RIC) and service management and orchestration (SMO).

[0289] The near real-time RIC is primarily used to collect network information and perform necessary optimization tasks. The near real-time RIC communicates with the O-CU and O-DU via the E2 interface. The near real-time RIC may include a QoS management module, a radio connection management module, an interference management module, and a mobility management module.

[0290] The SMO can include multiple functional modules, such as non-real-time RIC, configuration, policy, design, and inventory modules. The main functions of the SMO can include cloud infrastructure operation, administration, and maintenance (OAM). For example, it can operate, maintain, and manage cloud infrastructure through the O2 interface. The SMO can also operate, maintain, and manage the RAN through the O1 interface. The SMO can also include a non-real-time RIC, such as one that combines artificial intelligence (AI) and big data analytics to achieve non-real-time macro-control and intervention of the O-RAN through the A1 interface. Each functional entity in the O-RAN can function as an independent entity, communicating with the SMO independently using the O1 interface. In some examples, the SMO and near-real-time RIC can communicate via either the A1 or O1 interface; the appropriate communication path can be selected based on the specific circumstances, which will not be elaborated further in this embodiment.

[0291] Figure 15 is a schematic diagram of a communication method provided by an embodiment of this application.

[0292] This communication process is applicable to, but not limited to, the communication scenarios shown in Figures 1 and 14. This method can be applied to long-term evolution (LTE), LTE frequency division duplex (FDD) systems, LTE TDD, 5G or NR systems, future communication systems (such as future communication systems), V2X (where V2X can include vehicle-to-network (V2N), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), long-term evolution-vehicle (LTE-V), vehicle-to-everything (V2X), MTC, IoT, long-term evolution-machine (LTE-M), machine-to-machine (M2M), and D2D wireless communication scenarios. The method may include the following steps:

[0293] S101, the network device generates the first signal block.

[0294] For example, a first signal block may include a first signal and a second signal. For instance, the first signal may include the aforementioned PSS and / or SSS. Similarly, the second signal may include the aforementioned PBCH. The first signal block can be carried on at least one symbol; for example, the first signal block may occupy one or more symbols. The first signal and the second signal can be frequency-division multiplexed on any one of the at least one symbols. For example, any one of the at least one symbols can be called a target symbol. Then, the first signal and the second signal can be frequency-division multiplexed on that target symbol. Compared to a traditional SSB, the time-domain symbol containing the PSS is not frequency-division multiplexed with any other signal and / or channel. That is, the signal is exclusively used by the PSS. However, in the first signal block of this application, regardless of which symbol it occupies, the first signal, including the PSS and / or SSS, can be frequency-division multiplexed with the second signal, including the PBCH, on that symbol.

[0295] It is worth noting that in the embodiments of this application, a signal block refers to a specific time-frequency resource structure that can carry signals and / or channels. A signal refers to the signal and / or channel carried in the signal block. Here, a channel can be considered as a logical path through which a signal is transmitted. To a certain extent, mentioning a channel can evoke the signal transmitted on that channel, and mentioning a signal can evoke the channel through which the signal is transmitted. Therefore, signal and channel can be considered to have similar meanings and can be used interchangeably under certain conditions.

[0296] To a certain extent, the symbols occupied by the first signal block in this application embodiment can carry more signals and / or channels. Therefore, for a traditional SSB, the symbols occupying a PSS can be saved, and the terminal can sleep on those symbols. Alternatively, assuming there are other signals that would normally require other symbols for transmission, then in this application, the symbols corresponding to the traditional PSS can be used. This means that the symbols originally occupied by those other symbols can be saved, and the terminal can sleep on those symbols.

[0297] In some embodiments, the first signal block may be called any name such as energy-saving signal block, high-efficiency signal block, synchronization signal block, SSB, etc., and the embodiments of this application are not limited thereto.

[0298] In some embodiments, a possible structure for a first signal block is provided. For example, for any symbol carrying the first signal block, such as a target symbol, the first signal can occupy N first frequency domain resources, and the second signal can occupy M second frequency domain resources. Then, P first frequency domain resources can be located at one end or both ends of S second frequency domain resources. One possibility is that P consecutive first frequency domain resources can be located at one end or both ends of S consecutive second frequency domain resources. For example, N and M are positive integers, P first frequency domain resources belong to N first frequency domain resources, that is, P is less than or equal to N; S second frequency domain resources belong to M second frequency domain resources, that is, S is less than or equal to M. It is understood that the quantities represented by the letters in the above examples mainly reflect the size relationship of quantities, and the above letters can also be equivalently replaced by other letters or numerical values, which are not limited in this embodiment.

[0299] In other words, the first signal can occupy a first number (e.g., N) of the first frequency domain resources, and the second signal can occupy a second number (e.g., M) of the frequency domain resources. On a symbol (e.g., the target symbol) occupied by the first signal, the resources can be distributed sequentially according to a third number (e.g., P) of the first frequency domain resources and a fourth number (e.g., S) of the second frequency domain resources. The two ends of the target symbol in the frequency domain can belong to the first frequency domain resources and the second frequency domain resources, respectively. Alternatively, it can belong to both the first and second frequency domain resources simultaneously. This application does not limit the scope of the embodiments.

[0300] For example, a frequency domain resource can be understood as a frequency domain resource corresponding to a certain frequency domain unit. This could be a single RE, a single RB, a sub-band, or a frequency band, etc., and this application embodiment does not impose any limitations. Alternatively, a frequency domain resource can be understood as a complete segment of frequency domain resources, such as 24 REs, 3 RBs, etc. The above values ​​are merely illustrative examples and are not intended to limit the scope of this application embodiment.

[0301] Referring to Figure 16, one possible structure of the first signal block is shown. It can be seen that regardless of which symbol the first signal block occupies, the first and second frequency domain resources on that symbol are alternated; this can be called interleaved mapping. For example, if each first and second frequency domain resource is a complete segment of frequency domain resources, then it can be considered that the first and second signals are alternately mapped on any symbol in the first signal block. Of course, the two ends of each symbol in the frequency domain can map the same signal, such as both being the first signal or both being the second signal. Alternatively, different signals can be mapped, such as one end mapping the first signal and the other end mapping the second signal.

[0302] It is understood that Figure 16 only shows the case of two symbols, and may actually include more or fewer symbols, which is not limited in the embodiments of this application.

[0303] Figure 17 illustrates another possible structure for the first signal block. Taking an example where the first signal includes PSS and / or SSS, and the second signal includes PBCH, Figure 17 is similar to Figure 16, except that in the first signal block of Figure 17, PSS can occupy a single symbol, and the remaining symbols are interleaved between SSS and PBCH. For example, the symbols interleaved between SSS and PBCH can include one or more, such as one or two. The third symbol in the first signal block shown in the left half of Figure 17 is an optional symbol.

[0304] Assuming the symbols interleaved by SSS and PBCH are called interleaved symbols, then optionally, the symbols occupied by PSS and the aforementioned interleaved symbols can be two adjacent symbols, or separated by at least one symbol. For example, a one-symbol interval, as shown in the second symbol of the first signal block in the right half of Figure 17, is an idle symbol.

[0305] This application provides a specific form of frequency domain allocation for signal blocks, which allows signal blocks composed in this way to occupy as few symbols as possible while transmitting corresponding signals, thereby increasing the time domain positions where the terminal can sleep and reducing terminal power consumption.

[0306] In some examples, for a first signal block that alternately maps the first and second signals as described above, the first signal can be used to demodulate the second signal. For example, the second signal can be demodulated using the PSS and / or SSS in the first signal. Taking the second signal including PBCH as an example, the PSS can be used for PBCH demodulation; or, the SSS can be used for PBCH demodulation; or, both PSS and SSS can be used for PBCH demodulation. For example, a certain calculation method can be pre-configured so that the terminal receives the correct first signal. The terminal then compares the received first signal to determine the channel condition between the terminal and the network device and estimates the channel matrix. The terminal can then use this channel matrix to demodulate the second signal. Of course, a potentially correct first signal can also be pre-configured so that the terminal completes the above demodulation process for the second signal. This application does not limit the embodiments. In some cases, the terminal demodulation process can be similar to the process of demodulation via DMRS. For specific implementation, please refer to relevant technologies, which will not be repeated in this application. In this case, the second signal may still include DMRS or may not. For example, if the second signal still includes DMRS, more accurate channel estimation can be achieved with less modification to the PBCH, making the embodiments of this application more adaptable. Alternatively, if the second signal does not include DMRS, it can allocate more resources to data transmission compared to a traditional PBCH, thereby improving data transmission efficiency.

[0307] Optionally, taking the first signal block shown in Figure 17 as an example, the PBCH of this first signal block may or may not include DMRS; this application embodiment does not impose any limitations. Optionally, the device receiving the first signal block can demodulate the PBCH based on one or more of the PSS, SSS, or DMRS in the PBCH. For example, the PBCH can be demodulated using the DMRS in the PBCH; or, it can be demodulated using the SSS; or, it can be demodulated using both the SSS and the DMRS in the PBCH; or, it can be demodulated using both the PSS, SSS, and the DMRS in the PBCH. This application embodiment will not list all of these options, and does not impose any limitations.

[0308] In this embodiment, the first signal, including PSS and SSS, can also be used to demodulate the second signal. When the second signal still includes DMRS, more accurate channel estimation can be achieved, and universality can be improved. When the second signal does not include DMRS, the data transmission efficiency of the second signal can be improved.

[0309] In other embodiments, a possible structure for the first signal block is provided. For example, for any symbol carrying the first signal block, such as a target symbol, the first signal can occupy N first frequency domain resources, and the second signal can occupy M second frequency domain resources. Then, P first frequency domain resources can be located at one end or both ends of the M second frequency domain resources. One possibility is that P consecutive first frequency domain resources can be located at one end or both ends of the M second frequency domain resources. That is, on the target symbol, the first frequency domain resources can be located at one end of a complete second frequency domain resource, or at both ends of a complete second frequency domain resource. Here, a complete second frequency domain resource can be understood as the second signal occupying a continuous segment of frequency domain resources on that symbol.

[0310] Referring to Figures 18 and 19, possible structures of the first signal block are shown. For example, in Figure 18, the first frequency domain resources occupied by the first signal can be located at both ends of the second frequency domain resources occupied by the second signal. Alternatively, in Figure 19, the first frequency domain resources occupied by the first signal can be located at one end of the second frequency domain resources occupied by the second signal. In this case, the DMRS can still be retained in the second signal for the terminal to demodulate the second signal based on the DMRS.

[0311] In some examples, the mapping method of the first signal and the second signal in the first signal block shown in Figures 18 and 19 can also be called non-interleaved mapping, block frequency division mapping, etc., and the embodiments of this application do not limit this.

[0312] This application provides a specific form of frequency domain allocation for signal blocks, which allows signal blocks composed in this way to occupy as few symbols as possible while transmitting corresponding signals, thereby increasing the time domain positions where the terminal can sleep and reducing terminal power consumption.

[0313] In some embodiments, regardless of the structure of the first signal block, the number of symbols occupied by the first signal block can be less than or equal to 3. That is, compared with the traditional SSB, the first signal block of this application embodiment occupies fewer symbols. For example, it occupies 2 symbols. Alternatively, it can occupy 3 symbols or 1 symbol; this application embodiment does not limit this.

[0314] In this embodiment, the first signal block can occupy three or even fewer symbols, which can free up more time-domain resources for the terminal to hibernate and reduce terminal power consumption compared to the traditional SSB.

[0315] In some embodiments, for any of the above-described first signal block structures, the first signal on the same symbol can be either a PSS or an SSS. That is, the first signal on different symbols can respectively carry the PSS and SSS. This allows the first signal in this application to isolate the PSS and SSS using a time-division multiplexing method, while also multiplexing it with the second signal on each symbol using a frequency-division multiplexing method. This improves the management efficiency of the first signal and frees up more time-domain resources for the terminal to sleep, reducing terminal power consumption. Alternatively, for any of the above-described first signal block structures, for the same symbol, the first signal can be either a PSS or an SSS. For example, different first frequency domain resources on the target symbol can respectively carry the PSS and SSS.

[0316] S102, the network device sends a first signal block to the terminal. Correspondingly, the terminal receives the first signal block from the network device.

[0317] For example, a network device can send the first signal block generated in S101 to a terminal. The terminal receives the first signal block.

[0318] S103, the terminal communicates based on the first signal block.

[0319] For example, the terminal can complete corresponding communication based on the first signal block. For example, it can complete initial access, such as the terminal completing one or more of cell search, synchronization, or obtaining system messages based on the first signal block, or the terminal can complete any other possible communication based on the first signal block.

[0320] In some embodiments, a first signal block can be used for initial access. The terminal can then complete the initial access based on this first signal block. For example, initial access may include one or more of cell search, synchronization, or obtaining system messages. Embodiments of this application provide various functions that may be included in initial access, improving system versatility.

[0321] For example, the first signal block can be used for channel state measurement. The terminal can then perform channel state measurement based on this first signal block, such as CSI-RS measurement, to obtain the CSI. Optionally, the terminal can also report this CSI to the network device.

[0322] For example, the first signal block can be used for paging. The terminal can then complete paging based on this first signal block. For instance, the terminal can complete paging based on the access network or the core network based on this first signal block; this embodiment does not limit the scope of the application.

[0323] For example, the first signal block can be used for service communication. The terminal can then complete service communication based on this first signal block. For instance, service communication may include one or more of service data communication, AI communication, or satellite communication. The embodiments of this application provide a variety of possible service data communication scenarios, improving system versatility.

[0324] For example, the first signal block can be used for sensing. The terminal can then perform sensing based on the first signal block. For instance, the terminal can use the first signal block to sense its position, obstacles in the surrounding environment, speed, and height, etc. This embodiment of the application does not limit the scope of the sensing.

[0325] In some examples, the first signal block can be used for: initial access and sensing; or, initial access, paging and service communication; or, initial access, channel state measurement, service communication and sensing; or, initial access, channel state measurement, paging, service communication and sensing. It is understood that the first signal block in this application embodiment can also be used for any of the above possible communication functions, and this application embodiment will not list them all.

[0326] This application provides various communication scenarios in which the first signal block can be used, so that in different communication scenarios, the first signal block can be used to increase the time domain position of the terminal sleep while completing the corresponding communication, thereby reducing the terminal power consumption.

[0327] This application embodiment allows different signals in a signal block to be frequency-division multiplexed on any one symbol, enabling signals originally distributed across different symbols to be transmitted on the same symbol. This means that symbols that were originally used separately for each signal are now idle, allowing the terminal to be configured to sleep or used to transmit other signals. This allows the terminal to configure sleep on the time slots originally occupied by other signals, thereby increasing the time-domain locations where the terminal can sleep and reducing its power consumption.

[0328] In the communication method provided in this application embodiment, taking the first signal block structure shown in Figures 16, 17, 18, and 19 as an example, it is assumed that the terminal occupies 2 symbols, such as 2 OFDM symbols. It is assumed that the first signal in the first symbol is PSS, and the first signal in the second symbol is SSS; or the first signal in the first symbol is SSS, and the first signal in the second symbol is PSS. It is assumed that the SCS is 30kHz, and the corresponding frequency domain bandwidth can be 10MHz; or the SCS is 15kHz, and the corresponding frequency domain bandwidth can be 5MHz. Then each symbol can occupy 24 RBs in the frequency domain. The total length of the first frequency domain resources occupied by the PSS or SSS on each symbol can be 144 REs. The remaining 144 REs on each symbol can be used for a second signal such as PBCH.

[0329] In some cases, assuming that the frequency domain resources occupied by the first signal are considered to be in the second frequency domain resources occupied by the second signal, it can also be assumed that the second signal occupies 288 REs per symbol, of which 144 REs are used for the first signal (such as PSS and / or SSS).

[0330] Taking Figure 16 as an example, the starting position of the RE index of the first frequency domain resource corresponding to the second signal can be 0. Assuming that each second frequency domain resource on each symbol in Figure 16 occupies K REs, then the starting position of the RE index of the first frequency domain resource corresponding to the first signal can be K-1, where K is a positive integer. Then, the starting position of the RE index of the second frequency domain resource corresponding to the second signal can be K, and so on. Of course, the frequency domain resources of the first and second signals can be replaced. For example, the starting position of the RE index of the first frequency domain resource corresponding to the first signal can be 0, and the starting position of the RE index of the first frequency domain resource corresponding to the second signal can be K-1, etc. This application embodiment does not limit this.

[0331] For the symbols in Figure 17 where PSS and PBCH are interleaved, the frequency domain resource locations of each signal can be referred to the relevant description in Figure 16. For the resource location of the first symbol, PSS, refer to the resource location of PSS in related technologies. Further details are omitted in the embodiments of this application.

[0332] Taking Figure 18 as an example, the starting position of the RE index of the first frequency domain resource corresponding to the first signal can be 0. Assuming that each first frequency domain resource on each symbol in Figure 18 occupies K' REs, then the starting position of the RE index of the first frequency domain resource corresponding to the second signal can be K'-1, where K' is a positive integer. Assuming that each second frequency domain resource on each symbol in Figure 18 occupies 144 REs, then the starting position of the RE index of the second frequency domain resource corresponding to the first signal can be K'+143.

[0333] Taking Figure 19 as an example, for the structure of the two symbols on the left, the starting position of the RE index of the frequency domain resource corresponding to the first signal can be 0. Assuming that the first frequency domain resource occupies 144 REs on each symbol in Figure 19, then the starting position of the RE index of the frequency domain resource corresponding to the second signal can be 143. Similarly, for the structure of the two symbols on the right, the starting position of the RE index of the frequency domain resource corresponding to the second signal can be 0. Assuming that the second frequency domain resource occupies 144 REs on each symbol in Figure 19, then the starting position of the RE index of the frequency domain resource corresponding to the first signal can be 143.

[0334] It is understandable that the frequency domain resource locations of each signal in the first signal block can be determined, for example, through a table or a formula corresponding to the time domain location in a diagram similar to that in an SSB diagram. The principle is to map the signals at intervals as shown in Figures 16, 17, 18, or 19. Specific values ​​can be determined based on actual circumstances, and this application embodiment does not impose limitations. The amount of frequency domain resources occupied in the above examples is merely an illustrative description; more or less frequency domain resources can be occupied depending on actual circumstances, and this application embodiment does not impose limitations.

[0335] This application implements various first signal implementations that can effectively reduce time-domain symbols, lower resource overhead, and reduce terminal power consumption. For first signal blocks with structures similar to those shown in Figures 16 and 17, the PSS and / or SSS can be multiplexed for channel estimation in the PBCH, thereby reducing resource overhead and enabling compatibility with low-bandwidth communication scenarios. For first signal blocks with structures similar to those shown in Figures 18 and 19, PBCH performance is not compromised, and the performance of the PSS and / or SSS is improved through frequency division multiplexing. It is also applicable to communication scenarios with larger minimum bandwidths, such as millimeter wave (mmW) and FR3 (e.g., terahertz (THz)). The embodiments in this application are not limited to these specific scenarios.

[0336] In the communication method provided in this application embodiment, the network device can configure multiple periods for a first signal block simultaneously. For example, candidate values ​​for multiple periods of the first signal block can be pre-selected, such as those predefined by the protocol or pre-configured through other means. The candidate values ​​for multiple periods can be similar to {5ms, 10ms, 20ms, 40ms, 80ms, ...}. The network device selects multiple values ​​from these candidate values ​​to simultaneously serve as the periods of the first signal block. Alternatively, the candidate values ​​for multiple periods can be similar to {(5ms, 10ms), (10ms, 20ms), (5ms, 40ms), (10ms, 80ms), ...}. Each candidate value can correspond to two period values. The network device selects one set of candidate values ​​as the period of the first signal block. Of course, this example only shows the case where two periods are used as a set of candidate values. In other examples, a set of candidate values ​​can include values ​​of more periods, such as values ​​of three periods, etc., which is not limited in this application embodiment.

[0337] The network device in this application embodiment can configure multiple cycles for the first signal block at the same time. Compared with the traditional SSB which only configures one cycle at a time, the first signal block with different cycles can more flexibly adapt to different communication scenarios.

[0338] In some embodiments, the network device may configure multiple cycles for the first signal block, including a first cycle and a second cycle. The network device can then send the first signal block to the terminal based on the first cycle and / or the second cycle. Correspondingly, the terminal can receive the first signal block based on the first cycle and / or the second cycle. For example, the value of the first cycle can be greater than the value of the second cycle. Alternatively, the value of the second cycle can be considered less than the value of the first cycle. That is, assuming the network device configures multiple cycles for the first signal block including two cycles, the value of one cycle can be greater than the value of the other cycle. This cycle value corresponds to values ​​such as 5ms, 10ms, 20ms, etc., as mentioned above. It can also be referred to as the cycle length, cycle duration, cycle duration, etc., which are not limited in this embodiment.

[0339] For example, a network device can send a first signal block to a terminal using a first cycle. Correspondingly, the terminal can receive the first signal block based on the first cycle. Alternatively, the network device can send the first signal block to the terminal using a second cycle. Correspondingly, the terminal can receive the first signal block based on the second cycle. In other words, although the network device may configure multiple cycles for the first signal block, such as two cycles, it can still send the first signal block to the terminal using only one of these cycles. For example, it can send the first signal block using a cycle with a shorter value, or it can send the first signal block using a cycle with a longer value.

[0340] For example, a network device can simultaneously send a first signal block to a terminal using both a first cycle and a second cycle. Therefore, the terminal can also simultaneously receive first signal blocks sent by the network device based on different cycles.

[0341] In this embodiment of the application, the network device may send the first signal block in one or more cycles, so as to be able to adapt to multiple communication scenarios at the same time and improve the system's versatility.

[0342] In some examples, the network device can also inform the terminal via a second signal block which cycle the network device will subsequently use to transmit the first signal block. Therefore, the method may further include: the network device sending a second signal block to the terminal. Accordingly, the terminal receives the second signal block sent by the network device. For example, the second signal block may be used to indicate the first cycle and / or the second cycle.

[0343] For example, the second signal block can directly indicate the first period and / or the second period, and the terminal determines which period to use to receive the first signal block based on the period indicated by the second signal block. Alternatively, the second signal block can trigger the terminal to use the first period and / or the second period to receive the first signal block. Or, the second signal block can be used to activate the first period and / or the second period. The terminal then uses the corresponding period (or the activated period) to receive the first signal block.

[0344] In some examples, the structure of the second signal block can be the same as that of the first signal block. The structure of the second signal block can also differ from that of the first signal block; this application does not limit the specific implementation of the embodiments.

[0345] The network device in this application embodiment can also flexibly inform the terminal which cycle to use to receive the first signal block, so that the terminal can accurately receive the first signal block and improve communication efficiency.

[0346] In some embodiments, the first signal block may be configured with multiple resource patterns. For example, the resource pattern may be similar to the SSB pattern mentioned above, except that each SSB is replaced by the first signal block provided in the embodiments of this application. Of course, any other possible resource pattern can be used, and this application does not limit the style of the specific resource pattern.

[0347] In some examples, different resource patterns can be used for different periods, so the resource pattern for some periods can be a uniform resource pattern. For instance, within a period, the resource pattern of the first signal block is periodically configured on the corresponding time-domain resources according to a certain pattern. In this case, the period can also be considered a uniform period. On the other hand, the resource pattern for some periods can be a non-uniform resource pattern. For instance, within a period, the resource pattern of the first signal block is configured on the corresponding time-domain resources, but not generated in a fixed manner. In this case, the period can also be considered a non-uniform period, or aperiodic.

[0348] For example, consider the aforementioned multiple cycles, including a first cycle and a second cycle. For instance, both the first and second cycles are uniform cycles, or the resource patterns of the first signal block in both cycles are considered uniform resource patterns. Referring to Figure 20, assume the first signal block is configured with two cycles; the first signal block in cycle 1 corresponds to resource pattern 1, and the first signal block in cycle 2 corresponds to resource pattern 2. It can be seen that the first signal block in cycle 1 is uniformly mapped at its corresponding time-domain position according to a 20ms cycle. Similarly, the difference between cycle 2 and cycle 1 lies in the different values ​​of the cycle, such as 40ms, which will not be elaborated further in this embodiment. Referring to Figure 21, similar to Figure 20, the difference is that cycles 1 and 2 in Figure 21 are non-uniform cycles. Correspondingly, the resource patterns of the first signal block in each cycle are also non-uniform resource patterns. For example, the length of the interval between two adjacent mapped first signal blocks in cycles 1 and 2 is different.

[0349] For example, one of the two cycles may be a uniform cycle, and the other a non-uniform cycle. Alternatively, the resource pattern of the first signal block may be considered uniform in one cycle and non-uniform in the other. For a uniform cycle, mapping can be performed as shown in Figure 20; for a non-uniform cycle, mapping can be performed as shown in Figure 21. Further details are omitted in this embodiment.

[0350] In this embodiment, the first signal block can be mapped to a corresponding time-domain position within a period according to a uniform or non-uniform resource pattern. This allows for the appropriate mapping of the first signal block in different communication scenarios, improving system versatility.

[0351] In some embodiments, multiple cycles configured for a first signal block by the network device can be used for different communication functions. For example, a first signal block with one cycle can be used for initial access, while a first signal block with another cycle can be used for sensing. Alternatively, a first signal block with one cycle can be used for AI communication, while a first signal block with another cycle can be used for sensing, etc. Different communication functions can refer to the communication functions corresponding to the channels and / or signals included in the aforementioned first signal block for different communications, which will not be elaborated further in this application embodiment. Of course, other possible communication functions may also be included, and this application embodiment does not limit them. In some examples, multiple cycles can also be used to jointly implement a certain communication function, such as jointly implementing a sensing function to improve sensing performance. Alternatively, multiple cycles can all be used for initial access, the difference being that the values ​​of some cycles may be relatively larger than the values ​​of some cycles.

[0352] For example, configuring first signal blocks with different periods can be used for energy-saving and / or non-energy-saving scenarios respectively. For instance, for multiple periods of the first signal block configured in a network device, periods with relatively larger period values ​​can be used for energy-saving scenarios. This is because a larger period means that more time-domain resources can be used for terminal sleep within that period. Periods with relatively smaller period values ​​can be used for non-energy-saving scenarios. For example, some communication scenarios may require frequent signal measurements to meet requirements such as low latency and high quality of service (QoS). Such scenarios can be achieved using first signal blocks with relatively smaller period values. In some examples, different periods can both be used for energy-saving scenarios, the difference being that the energy-saving effect may differ. These two periods can be uniform periods and / or non-uniform periods, which is not limited in this application embodiment.
