Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a communication method and corresponding device. Background Technology

[0002] Each generation of wireless communication systems typically has more antennas and is deployed at higher frequencies compared to the previous generation. For example, the 4th generation (4G) is deployed at 2GHz, and 4G base stations typically use 4-transmission (4T) antennas. The 5th generation (5G) is deployed at 3.5GHz, and 5G base stations typically use 64T antennas. Compared to 4G, because 5G has more antennas and higher frequencies, it employs beam scanning to improve signal coverage. This involves using more antennas to form a narrower beam to compensate for signal attenuation caused by the higher frequency. Regarding beam scanning, taking common signals as an example, current protocols only support time-division multiplexing (TDM) scanning for multiple beams. This means that only one common beam can be transmitted at a time, and multiple common beams require multiple scanning times.

[0003] The advantage of using time-division multiplexing for scanning a common beam is that it can achieve the largest possible antenna gain at any given time, but it is not advisable from an energy-saving perspective. Specifically, multi-beam scanning using time-division multiplexing takes a long time, preventing the base station from entering sleep mode and increasing the time for terminal equipment to perform beam measurements, thus increasing the power consumption of the terminal equipment.

[0004] Future communication networks will likely employ more antennas and be deployed at higher frequencies. This means more beams will be needed to improve signal coverage, further exacerbating the power consumption issues associated with beam scanning. Summary of the Invention

[0005] This application provides a communication method for reducing power consumption caused by beam scanning. This application also provides corresponding apparatus, computer-readable storage media, and computer program products.

[0006] The first aspect of this application provides a communication method applicable to a first communication device. The method includes: receiving a target common signal; wherein the target common signal is at least one first common signal in a first signal set, the first signal set includes multiple first common signals, a first resource configuration of the first signal set includes a frequency division multiplexing configuration, at least two of the multiple first common signals are simultaneously transmitted using frequency division multiplexing, and at least one of the multiple first common signals is measured according to the first resource configuration.

[0007] In one possible implementation, the first communication device further receives resource configuration indication information, wherein the resource configuration indication information is used to indicate the first resource configuration.

[0008] In this application, the first communication device may also be a terminal device, a component or device applied to the terminal device (such as a processor, chip, or chip system), or a logic module or software that can realize all or part of the functions of the terminal device.

[0009] In this application, the target public signal and resource configuration indication information may be sent by a second communication device. The second communication device may be a network device, or a component or device applied to the network device (such as a processor, chip, or chip system, etc.), or a logic module or software that can realize all or part of the functions of the network device (such as a central unit (CU), a distributed unit (DU), or a radio unit (RU, etc.).

[0010] In this application, the first common signal includes a synchronization signal (SS), or the first common signal includes an SS and a physical broadcast channel (PBCH). The SS typically includes a primary synchronization signal (PSS) and / or a secondary synchronization signal (SSS); the PBCH typically includes a Master Information Block (MIB). The SS and PBCH are also commonly referred to as (synchronization signal and PBCH block, SSB). The MIB may include information such as the radio frame number, time-frequency resource configuration information of the physical downlink control channel (PDCCH), or the index of the first common signal, where each index value can characterize the resource location and / or the direction of the transmission beam of the first common signal.

[0011] In this application, the first signal set refers to a set that includes multiple first common signals. If the first common signal is represented by SSB, then the first signal set may include multiple SSBs. For example, if the first signal set includes 8 first common signals, then the first signal set can be represented as {SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, SSB8}.

[0012] In this application, the resource configuration indication information may be included in the first common signal or transmitted independently of the first common signal, such as through the physical downlink shared channel (PDSCH). This resource configuration indication information can at least indicate frequency division multiplexing (FDM) configuration.

[0013] In the first aspect mentioned above, for multiple signals in the first signal set, it is not necessary to transmit them one by one in the manner of time division multiplexing (TDM). Instead, at least two of the first common signals can be transmitted simultaneously in the manner of frequency division multiplexing. This shortens the time for the second communication device to transmit multiple first common signals and also shortens the time for the first communication device to measure multiple first common signals. This reduces the power consumption of the second communication device in beam scanning and the power consumption of the first communication device in signal measurement.

[0014] It should be noted that the aforementioned multiple first common signals can also be transmitted in a time-division manner using TDM.

[0015] In one possible implementation, the first resource configuration further includes a time-division multiplexing configuration, wherein at least two of the multiple first common signals are transmitted in a time-division multiplexing manner.

[0016] In this possible implementation, the first resource configuration includes not only FDM configuration but also TDM configuration. For example, in the first signal set, there are eight first common signals {SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, SSB8}. SSB1, SSB2, SSB3, and SSB4 can be transmitted using FDM at the first time, while SSB5, SSB6, SSB7, and SSB8 can be transmitted using FDM at the second time. The four first common signals transmitted at the first time and the four first common signals transmitted at the second time are TDM-transmitted first common signals. In this application, multiple first common signals are transmitted using a combination of FDM and TDM, which, while considering timing, can also reduce excessive occupation of frequency domain resources.

[0017] In one possible implementation, the method further includes: receiving at least one second common signal from a second signal set; wherein the second signal set includes multiple second common signals, and the resources of the common physical downlink control channel (PDCCH) occupied by the multiple second common signals belong to at least one common control resource set; and the resources occupied by at least two first common signals have a many-to-one association relationship with at least one common control resource set.

[0018] In this application, the second common signal may include a first PDCCH, which may include scheduling information. The scheduling information is used to schedule the PDSCH, which carries SIB1, on-demand SIs, and paging messages from system information (SI). SIB1 is information carried on the PDSCH in the necessary SIs; necessary SIs are those required for cell camping and access, while on-demand SIs are non-urgent SIs, generally including cell reselection and other auxiliary SIs. The first PDCCH may also include common control information, which may or may not schedule the PDSCH. This common control information includes at least one of the following: independent system messages that do not require PDCCH scheduling (such as some or all system messages carried in the aforementioned PBCH or MIB), paging advance indication, paging wake-up information, SI change indication, and SI indication information.

[0019] In this application, the second common signal may further include a second common PDCCH, which, unlike the first common PDCCH, is a scheduling information or common control information at the next lower level than the first PDCCH. For example, the first common PDCCH carries scheduling or control information for the cell common SI, and the second common PDCCH carries scheduling or control information for the beam common SI; wherein, a cell includes multiple beams, and a cell can be represented by a cell identifier, while a beam can be identified by an SSB index or other beam index. Alternatively, the first common PDCCH carries scheduling or control information for the area common SI, and the second common PDCCH carries scheduling or control information for the cell common SI; wherein, an area includes multiple cells, and an area can be represented by an area ID, while cells are represented by cell identifiers.

[0020] In this application, the time-frequency resources occupied by the second common signal can be composed of a control resource set (CORESET) and a common search space (CSS). The CORESET includes multiple resource blocks (RBs) in the frequency domain, and the CSS includes time-domain detection positions, such as the positions of detection symbols in specific detection time slots or further detection time slots.

[0021] In this possible implementation, the resources occupied by at least two first common signals have a many-to-one association with at least one common control resource set. In this way, when sending or receiving a second common signal, multiple second common signals can use one common control resource set to send or receive, which can improve the strength and diversity gain of the second common signal.

[0022] In one possible implementation, the resources occupied by the first common signals transmitted at different times are associated with different sets of common control resources; and / or, the resources occupied by at least two frequency division multiplexed first common signals transmitted at the same time are associated with the same set of common control resources.

[0023] In this possible implementation, the resources occupied by the first public signal correspond to the set of public control resources, which can improve the speed at which the first communication device measures the second public signal.

[0024] In one possible implementation, the above step of receiving at least one second common signal from the second signal set includes: receiving at least one second common signal from the second signal set through a first transmission mode, wherein the first transmission mode includes a single frequency network (SFN) mode or a multi-antenna port mode; wherein, in the SFN mode, multiple beams transmit the same information at the same frequency and at the same time, and in the multi-antenna port mode, multiple beams transmit information through independent antenna ports.

[0025] In this possible implementation, using SFN mode or multi-antenna port mode to receive the second common signal can improve signal strength and diversity gain.

[0026] In one possible implementation, receiving at least one second common signal from a second signal set via a first transmission mode includes: receiving at least one second common signal from a second signal set according to transmission configuration information, wherein the transmission configuration information is used to indicate at least two transmit beams in SFN mode, or at least two antenna ports in multi-antenna port mode.

[0027] In this possible implementation, the transmission configuration information can be a transmission configuration indication (TCI). The TCI can indicate which transmission receiving points (TRPs) or beams will transmit the second common signal, and the beam index can be an SSB index. Multiple antenna ports can also be associated with beam identifiers or TRP identifiers, respectively. In this application, using transmission configuration information to indicate at least two transmit beams or at least two TRPs in SFN mode, or at least two antenna ports in multi-antenna port mode, can improve the reception speed of the second common signal.

[0028] In one possible implementation, the method further includes: transmitting a random access signal according to an uplink association; wherein the uplink association is the association between multiple resources occupied by a first signal set and at least one random access resource set; wherein the at least one random access resource set is a resource used to transmit a random access signal corresponding to the first signal set, and there is a many-to-one association between the resources occupied by at least two first common signals and at least one random access resource set.

[0029] In this possible implementation, the random access resource set refers to the random access channel (RACH) resource. In this application, there is a many-to-one association between the resources occupied by at least two first common signals and at least one random access resource set. Thus, when the first communication device uses a certain random access resource set to transmit a random access signal, the second communication device can use the multiple receiving beams associated with that random access resource set to receive the random access signal, thereby improving the strength and diversity gain of the random access signal.

[0030] In one possible implementation, the resources occupied by the first common signal transmitted at different times are associated with different sets of random access resources; and / or, the resources occupied by at least two frequency division multiplexed first common signals transmitted at the same time are associated with the same set of random access resources.

[0031] In this possible implementation, the resources occupied by the first public signal correspond to the set of random access resources, which can improve the accuracy of the first communication device in sending random access signals.

[0032] A second aspect of this application provides a communication method applied to a second communication device. The method includes: determining a first resource configuration for a first signal set; wherein the first signal set includes a plurality of first common signals, and the first resource configuration includes a frequency division multiplexing configuration; transmitting a target common signal according to the first resource configuration; wherein the target common signal is at least one of the plurality of first common signals, and at least two of the plurality of first common signals are transmitted simultaneously using a frequency division multiplexing method.

[0033] In one possible implementation, the second communication device sends resource configuration indication information, which is used to indicate the first resource configuration.

[0034] In the second aspect mentioned above, for multiple signals in the first signal set, it is not necessary to transmit them one by one in the manner of time division multiplexing (TDM). Instead, at least two of the first common signals can be transmitted simultaneously in the manner of frequency division multiplexing. This shortens the time for the second communication device to transmit multiple first common signals and also shortens the time for the first communication device to measure multiple first common signals. This reduces the power consumption of the second communication device in beam scanning and the power consumption of the first communication device in signal measurement.

[0035] It should be noted that the aforementioned multiple first common signals can also be transmitted in a time-division manner using TDM.

[0036] In one possible implementation, the first resource configuration further includes a time-division multiplexing configuration, wherein at least two of the multiple first common signals are transmitted in a time-division multiplexing manner.

[0037] In one possible implementation, the method further includes: transmitting at least one second common signal from the second signal set; wherein the second signal set includes multiple second common signals, and the resources of the common physical downlink control channel (PDCCH) occupied by the multiple second common signals belong to at least one common control resource set; and the resources occupied by at least two first common signals have a many-to-one association relationship with at least one common control resource set.

[0038] In one possible implementation, the resources occupied by the first common signals transmitted at different times are associated with different sets of common control resources; and / or, the resources occupied by at least two frequency division multiplexed first common signals transmitted at the same time are associated with the same set of common control resources.

[0039] In one possible implementation, the above step of transmitting at least one second common signal from the second signal set includes: transmitting at least one second common signal from the second signal set through a first transmission mode, wherein the first transmission mode includes a single-frequency network (SFN) mode or a multi-antenna port mode; wherein, in the SFN mode, multiple beams transmit the same information at the same frequency and at the same time, and in the multi-antenna port mode, multiple beams transmit information through independent antenna ports.

[0040] In one possible implementation, the above step of transmitting at least one second common signal from the second signal set through a first transmission mode includes: transmitting at least one second common signal from the second signal set according to transmission configuration information, wherein the transmission configuration information is used to indicate at least two transmit beams in SFN mode, or at least two antenna ports in multi-antenna port mode.

[0041] In one possible implementation, the method further includes: receiving random access signals according to uplink association; wherein the uplink association is the association between multiple resources occupied by a first signal set and at least one random access resource set; wherein the at least one random access resource set is a resource used to transmit random access signals corresponding to the first signal set, and there is a many-to-one association between the resources occupied by at least two first common signals and at least one random access resource set.

[0042] In one possible implementation, the resources occupied by the first common signal transmitted at different times are associated with different sets of random access resources; and / or, the resources occupied by at least two frequency division multiplexed first common signals transmitted at the same time are associated with the same set of random access resources.

[0094] The embodiments of this application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. As those skilled in the art will understand, with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0095] First, some terms used in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0096] (1) Terminal device: can be a wireless terminal device that can receive network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0097] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be called subscriber unit, subscriber station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc.

[0098] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0099] Terminals can also be drones, robots, devices in device-to-device (D2D) communication, vehicles to everything (V2X) communication, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in telemedicine or telehealth services, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0100] Furthermore, terminal devices can also be terminal devices in future communication systems beyond the fifth generation (5G) (such as 5G Advanced communication systems) or in future evolved public land mobile networks (PLMNs). For example, 5G Advanced networks can further expand the form and function of 5G communication terminals, including but not limited to vehicles, cellular network terminals (integrating satellite terminal functions), drones, and Internet of Things (IoT) devices.

[0101] In this embodiment, the terminal device can also obtain artificial intelligence (AI) services provided by the network device. Optionally, the terminal device can also have AI processing capabilities.

[0102] (2) Network equipment: This can be equipment within a wireless network. For example, network equipment can be a RAN node (or device) that connects terminal devices to the wireless network, and can also be called a base station. Currently, some examples of RAN equipment include: base station, evolved NodeB (eNodeB), gNB (gNodeB) in 5G communication systems, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), home base station (e.g., home-evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc. In addition, in a network architecture, network equipment can include central unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including both CU and DU nodes.

[0103] Optionally, the RAN node can also be a macro base station, micro base station, indoor station, relay node, donor node, or a radio controller in a cloud radio access network (CRAN) scenario. The RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0104] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU).

Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0106] Communication between access network devices and terminal devices follows a specific protocol layer structure.

[0114] (3) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural.

And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0115] (4) In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly through the air interface or sending indirectly through the air interface by other units or modules.

The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0120] This application can be applied to long-term evolution (LTE) systems, new radio (NR) systems, or future communication systems beyond 5G. These communication systems include at least one network device and / or at least one terminal device.

[0121] Please see Figure 1 This is a schematic diagram of the architecture of the communication system used in the embodiments of this application. Figure 1 As shown, the communication system may include a radio access network 100, and optionally, the communication system may also include a core network 200 and an Internet 300. The RAN 100 includes at least one RAN node 110 (e.g., Figure 1 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). Figure 1RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1 (Not shown in the image). Terminal device 120 is wirelessly connected to RAN node 110, and RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0122] In the aforementioned communication system, the advantage of using time-division multiplexing for scanning the common beam is that it can achieve the largest possible antenna gain at any given time, but this is not advisable from an energy-saving perspective. Specifically, multi-beam scanning using time-division multiplexing takes a long time, preventing the base station from entering sleep mode and increasing the time for terminal equipment to perform beam measurements, thus increasing the power consumption of the terminal equipment.

[0123] Based on the above reasons, embodiments of this application provide a communication method for reducing power consumption caused by beam scanning. This application describes the corresponding communication process from the perspective of the interaction between a first communication device and a second communication device. The first communication device can be a terminal device, a component or device applied to a terminal device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The second communication device can be a network device, a component or device applied to a network device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the network device's functions (e.g., CU, DU, or RU).

[0124] like Figure 2 As shown, the communication method provided in this application embodiment includes:

[0125] S201. The second communication device determines the first resource configuration of the first signal set.

[0126] The first signal set includes multiple first common signals, and the first resource configuration includes frequency division multiplexing configuration.

[0127] In this application, the first common signal includes a synchronization signal (SS), or the first common signal includes an SS and a physical broadcast channel (PBCH). The SS typically includes a primary synchronization signal (PSS) and / or a secondary synchronization signal (SSS); the PBCH typically includes a Master Information Block (MIB). The SS and PBCH are also commonly referred to as (synchronization signal and PBCH block, SSB). The MIB may include information such as the radio frame number, time-frequency resource configuration information of the physical downlink control channel (PDCCH), or the index of the first common signal, where each index value can characterize the resource location and / or the direction of the transmission beam of the first common signal.

[0128] In this application, the first signal set refers to a set that includes multiple first common signals. If the first common signal is represented by SSB, then the first signal set may include multiple SSBs. For example, if the first signal set includes 8 first common signals, then the first signal set can be represented as {SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, SSB8}.

[0129] S202. The second communication device transmits a target common signal according to the first resource configuration. Correspondingly, the first communication device receives the target common signal.

[0130] Optionally, the second communication device sends resource configuration indication information, and correspondingly, the first communication device receives the resource configuration indication information. The resource configuration indication information is used to indicate the first resource configuration.

[0131] The target common signal is at least one of a plurality of first common signals, and the resource configuration indication information is used to instruct at least two of the plurality of first common signals to be transmitted simultaneously using frequency division multiplexing.

[0132] In this application, the resource configuration indication information may be included in the first common signal or transmitted independently of the first common signal, such as through the physical downlink control channel (PDCCH) or the physical downlink shared channel (PDSCH). This resource configuration indication information can at least indicate frequency division multiplexing (FDM) configuration.

[0133] If the first resource configuration only includes FDM, it means that multiple first common signals in the first signal set are transmitted simultaneously. For example, if the first signal set is {SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, SSB8}, the transmission format of these 8 first common signals can be found in [reference needed]. Figure 3A and Figure 3B To understand.

[0134] like Figure 3A As shown, these eight first common signals can be transmitted through the same second communication device, which simultaneously transmits eight beams, each beam carrying one first common signal, such as... Figure 3A The eight beams in the signal carry eight first common signals: SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, and SSB8.

[0135] like Figure 3B As shown, these eight first common signals can be transmitted through multiple second communication devices, such as... Figure 3B There are four secondary communication devices (TRP1, TRP2, TRP3, and TRP4). Each of these four secondary communication devices transmits two beams. For example, TRP1 transmits two beams that carry SSB1 and SSB2 respectively, TRP2 transmits two beams that carry SSB3 and SSB4 respectively, TRP3 transmits two beams that carry SSB5 and SSB6 respectively, and TRP4 transmits two beams that carry SSB7 and SSB8 respectively.

[0136] S203. The first communication device measures at least one of a plurality of first common signals according to the first resource configuration.

[0137] Optionally, the first communication device acquires resource configuration indication information and determines the first resource configuration based on the resource configuration indication information.

[0138] The solution provided in this application embodiment allows the second communication device to transmit multiple signals in the first signal set one by one in a time division multiplexing (TDM) manner. Instead, at least two of the first common signals can be transmitted simultaneously in a frequency division multiplexing manner. This shortens the time for the second communication device to transmit multiple first common signals and also shortens the time for the first communication device to measure multiple first common signals. This reduces the power consumption of the second communication device in beam scanning and the power consumption of the first communication device in signal measurement.

[0139] The above Figure 3A and Figure 3B This paper describes the scenario where multiple first common signals are transmitted simultaneously using FDM. In practice, the first resource configuration in this application can also include time division multiplexing (TDM) configuration, where at least two of the multiple first common signals are transmitted using TDM. That is, the transmission of multiple first common signals involves both FDM and TDM configurations. For example, in the set of eight first common signals {SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7, SSB8}, SSB1, SSB2, SSB3, and SSB4 can be transmitted using FDM at the first moment, while SSB5, SSB6, SSB7, and SSB8 can be transmitted using FDM at the second moment. The four first common signals transmitted at the first moment and the four first common signals transmitted at the second moment are first common signals transmitted using TDM. In this application, the combination of FDM and TDM can be referred to as TFDM. For details on transmitting the above eight first common signals in a TFDM scenario, please refer to [reference needed]. Figure 3C and Figure 3D To understand.

[0140] like Figure 3C As shown, these eight first common signals can be transmitted through the same second communication device. This second communication device transmits four beams at the first moment (tl), with each beam carrying one first common signal, as shown below. Figure 3C The four beams in the signal carry SSB1, SSB2, SSB3, and SSB4 respectively. The second communication device transmits the four beams at a second time (t2), each beam carrying a first common signal, such as... Figure 3C The four beams in the signal carry the four first common signals, SSB5, SSB6, SSB7 and SSB8, respectively.

[0141] like Figure 3D As shown, these eight first common signals can be transmitted through multiple second communication devices, such as... Figure 3DThere are four secondary communication devices (TRP1, TRP2, TRP3, and TRP4). TRP1 and TRP2 transmit simultaneously at the first time (t1). For example, the two beams transmitted by TRP1 carry SSB1 and SSB2 respectively, and the two beams transmitted by TRP2 carry SSB3 and SSB4 respectively. TRP3 and TRP4 transmit simultaneously at the second time (t2). For example, the two beams transmitted by TRP3 carry SSB5 and SSB6 respectively, and the two beams transmitted by TRP4 carry SSB7 and SSB8 respectively.

[0142] In this embodiment, multiple first common signals are transmitted by combining FDM and TDM, which can reduce the excessive occupation of frequency domain resources while taking into account the timing.

[0143] Optionally, such as Figure 4 As shown, the communication method provided in this application embodiment further includes:

[0144] S401. The second communication device generates at least one second common signal in a second set of signals; wherein the second set of signals includes a plurality of second common signals.

[0145] In this application, the second common signal may include a first PDCCH, which may include scheduling information. The scheduling information is used to schedule the PDSCH, which carries SIB1, on-demand SIs, and paging messages from system information (SI). SIB1 is information carried on the PDSCH in the necessary SIs; necessary SIs are those required for cell camping and access, while on-demand SIs are non-urgent SIs, generally including cell reselection and other auxiliary SIs. The first PDCCH may also include common control information, which may or may not schedule the PDSCH. This common control information includes at least one of the following: independent system messages that do not require PDCCH scheduling (such as some or all system messages carried in the aforementioned PBCH or MIB), paging advance indication, paging wake-up information, SI change indication, and SI indication information.

[0146] In this application, the second common signal may further include a second common PDCCH, which, unlike the first common PDCCH, is a scheduling information or common control information at the next lower level than the first PDCCH. For example, the first common PDCCH carries scheduling or control information for the cell common SI, and the second common PDCCH carries scheduling or control information for the beam common SI; wherein, a cell includes multiple beams, and a cell can be represented by a cell identifier, while a beam can be identified by an SSB index or other beam index. Alternatively, the first common PDCCH carries scheduling or control information for the area common SI, and the second common PDCCH carries scheduling or control information for the cell common SI; wherein, an area includes multiple cells, and an area can be represented by an area ID, while cells are represented by cell identifiers.

[0147] In this application, the resources of the common physical downlink control channel (PDCCH) occupied by multiple second common signals belong to at least one common control resource set; the resources occupied by at least two first common signals have a many-to-one association relationship with at least one common control resource set.

[0148] In this application, the time-frequency resources occupied by the second common signal can be composed of a control resource set (CORESET) and a common search space (CSS). The CORESET includes multiple resource blocks (RBs) in the frequency domain, and the CSS includes time-domain detection positions, such as the positions of detection symbols in specific detection time slots or further detection time slots.

[0149] S402. The second communication device transmits at least one second common signal from the second signal set. Correspondingly, the first communication device receives at least one second common signal from the second signal set.

[0150] In this application, the relationship between the resources occupied by the first common signal and the resources occupied by the second common signal is related to TDM and FDM; if the first common signal and the second common signal are transmitted or received using TDM, the relationship between the corresponding resources can be found in [reference needed]. Figure 5A For clarification, if the first and second common signals are transmitted or received using pure FDM, the relationship between the corresponding resources can be found in [reference needed]. Figure 5B For clarification, if the first and second common signals are transmitted or received using TFDM (TDM+FDM) mode, the relationship between the corresponding resources can be found in [reference needed]. Figure 5C To understand.

[0151] like Figure 5AAs shown, when the second communication device transmits the first and second common signals using pure TDM, the eight first common signals, namely SSB1 to SSB8, are transmitted at different times; taking PDCCH as an example, the eight second common signals, namely PDCCH1 to PDCCH8, are transmitted at different times. There is a one-to-one relationship between the resources occupied by the transmission of SSB1 to SSB8 and the resources occupied by the transmission of PDCCH1 to PDCCH8. For example... Figure 5A As shown, the resources occupied by SSB1 correspond to those occupied by PDCCH1, the resources occupied by SSB2 correspond to those occupied by PDCCH2, the resources occupied by SSB3 correspond to those occupied by PDCCH3, the resources occupied by SSB4 correspond to those occupied by PDCCH4, the resources occupied by SSB5 correspond to those occupied by PDCCH5, the resources occupied by SSB6 correspond to those occupied by PDCCH6, the resources occupied by SSB7 correspond to those occupied by PDCCH7, and the resources occupied by SSB8 correspond to those occupied by PDCCH8.

[0152] like Figure 5B As shown, when the second communication device transmits the first and second common signals using pure FDM, the eight first common signals, namely SSB1 to SSB8, are transmitted simultaneously on different frequency domain resources; while the eight second common signals, namely PDCCH1 to PDCCH8, can be transmitted simultaneously on a single common control resource set. It is evident that there is an 8-to-1 relationship between the resources occupied by the eight first common signals and the resources occupied by the eight second common signals. If the number of first common signals is N, then according to... Figure 5B If the signals are sent in the manner shown, there is an N-to-one relationship between the resources occupied by the N first common signals and the resources occupied by the second common signals, where N is an integer greater than 1.

[0153] like Figure 5C As shown, when the second communication device transmits the first and second common signals using TFDM (TDM+FDM) mode, the four first common signals, namely SSB1 to SSB4, are transmitted simultaneously using different frequency domain resources at the first moment, while the four second common signals, namely PDCCH1 to PDCCH4, can be transmitted simultaneously on the same common control resource set 1. It is evident that there is a 4-to-1 relationship between the resources occupied by SSB1 to SSB4 and the common control resource set 1 occupied by PDCCH1 to PDCCH4.

[0154] The other four first common signals, SSB5 to SSB8, are transmitted simultaneously using different frequency domain resources at the second time point, while the four second common signals, PDCCH5 to PDCCH8, can be transmitted simultaneously on another common control resource set 2. Therefore, there is a 4-to-1 relationship between the resources occupied by SSB5 to SSB8 and the common control resource set 2 occupied by PDCCH5 to PDCCH8.

[0155] The above Figure 5B The pure FDM case described above, or Figure 5C In the cases where FDM and TDM are combined, there is a many-to-one relationship between the resources occupied by at least two first common signals and at least one common control resource set. Thus, when transmitting or receiving second common signals, multiple second common signals can use a single common control resource set for transmission or reception, which can improve the strength and diversity gain of the second common signals.

[0156] From the above Figure 5C As can be seen from the introduced scheme, the resources occupied by the first common signals transmitted at different times are associated with different sets of common control resources; and / or, the resources occupied by at least two frequency division multiplexed first common signals transmitted at the same time are associated with the same set of common control resources. For example, the resources occupied by SSB1 to SSB4 transmitted simultaneously are associated with the same set of common control resources 1; the resources occupied by SSB5 to SSB8 transmitted simultaneously are associated with the same set of common control resources 2; while SSB1 and SSB5 transmitted at different times are associated with different sets of common control resources, namely, common control resource set 1 and common control resource set 2 respectively.

[0157] The relationship between the resources occupied by the first public signal and the resources occupied by the second public signal can be called a downlink correlation relationship. Figure 5B and Figure 5C The downlink relationship between the resources occupied by the first public signal and the set of public control resources can be understood as the first downlink relationship; Figure 5A The relationship between the resources occupied by the first public signal and the resources occupied by the second public signal can be understood as a second downlink correlation.

[0158] In the above S402, the second communication device can transmit at least one second common signal from the second signal set through the first transmission mode; correspondingly, the first communication device can receive at least one second common signal from the second signal set through the first transmission mode; wherein, the first transmission mode includes a single frequency network (SFN) mode or a multi-antenna port mode; wherein, in the SFN mode, multiple beams transmit the same information at the same frequency and at the same time, and in the multi-antenna port mode, multiple beams transmit information through independent antenna ports.

[0159] SFN mode refers to multiple beams or multiple TRPs transmitting the same information simultaneously on the same frequency. This information is combined into a signal on the first communication device side, which can improve the strength of the received signal.

[0160] In this application, the multi-antenna port mode refers to multiple beams or multiple TRPs transmitting the same information through independent antenna ports. This allows for independent channel equalization and soft information merging on the first communication device side, thereby obtaining diversity and merging gains.

[0161] The aforementioned first transmission mode can be indicated by transmission configuration information, which indicates at least two transmit beams in SFN mode (e.g., beams identified by SSB indexes or other signal or resource indexes that can characterize beams), or at least two antenna ports in multi-antenna port mode.

[0162] The transmission configuration information can be a transmission configuration indication (TCI). This TCI can indicate which transmission receiving points (TRPs) or beams will transmit the second common signal, and the beam index can be an SSB index. For example, SSB1 is associated with beam 1, SSB2 with beam 2, or SSB1 to SSB4 with beams 1 to 4, etc. There can be various ways to indicate the TCI, and this application does not limit this.

[0163] Multiple antenna ports can also be associated with beam identifiers or TRP identifiers, respectively. Antenna port 1 can be associated with SSB1, antenna port 2 with SSB2, or antenna ports 1 through 4 can be associated with SSB1 through SSB4, etc. This application does not limit this. The antenna ports here are generally characterized by the demodulation reference signal of the second common signal. Associating an antenna port with an SSB index, as mentioned above, is equivalent to associating the demodulation reference signal with an SSB index. For example, demodulation reference signal 1, representing antenna port 1, is associated with SSB1, and demodulation reference signal 2, representing antenna port 2, is associated with SSB2.

[0164] In this application, by transmitting configuration information to specify at least two transmit beams or at least two TRPs in SFN mode, or at least two antenna ports in multi-antenna port mode, the reception speed of the second common signal can be improved.

[0165] The transmission configuration information (indication) of the first transmission mode can be determined by the first common signal or other SIs, or it can be determined based on the pure FDM, TFDM, or first downlink correlation relationships. For example, if the first common signal is determined to use the first resource configuration, then the first transmission mode (SFN mode or multi-antenna port mode) can be used to transmit or receive the second common signal. Of course, if the first common signal is determined to use the second resource configuration, i.e., pure TDM, then the second transmission mode (non-SFN mode or single-antenna port mode) can be used to transmit or receive the second common signal.

[0166] For information on SFN mode or multi-antenna port mode, please refer to [link / reference]. Figure 6 To understand, such as Figure 6 As shown, multiple TRPs can transmit a second common signal using either SFN mode or multi-antenna port mode.

[0167] Optionally, the public PDCCH in this embodiment supports the first communication device to use a low-power receiver for reception, such as on-off keying (OOK) or a sequence receiver. Specifically, it may have at least one of the following features:

[0168] The first PDCCH uses a switching modulation signal, with the most typical low-power wake-up signal being the academic OOK or frequency-shift keying (FSK) modulation signal. Taking OOK as an example, on a given time-frequency resource, the presence or absence of energy is detected to carry the raw bit information of downlink control information (DCI). Therefore, receiving OOK signals can be done with a low-power receiver, such as using envelope detection, which can achieve at least one order of magnitude lower receiving power consumption than a normal 5G OFDM receiver. FSK performs energy detection on two separate frequency resources to carry information, and is otherwise similar in essence to OOK.

[0169] The first PDCCH employs a sequence receiver, meaning the raw information bits of the first DCI are carried through the detection of multiple candidate sequences. For example, given N time-frequency resources, where each time-frequency resource can be used to transmit M sequences, then a maximum of N*log2M raw bit information can be carried. The terminal determines the aforementioned raw bit information by blindly detecting each candidate sequence on each time-frequency resource. The sequence receiver achieves low-power reception because sequence detection can be implemented through low-power correlation operations, which is much simpler than the complex channel estimation and encoding / decoding operations of traditional receivers.

[0170] Optionally, such as Figure 7 As shown, the communication method provided in this application embodiment further includes:

[0171] S701. The first communication device determines the uplink association relationship.

[0172] The uplink association is the association between multiple resources occupied by the first signal set or multiple first common signals included therein and at least one random access resource set; wherein, at least one random access resource set is a resource used to transmit random access signals corresponding to the first signal set, and there is a many-to-one association between the resources occupied by at least two first common signals and at least one random access resource set.

[0173] In this embodiment of the application, the random access resource set includes multiple random access resources, wherein each random access resource includes three resource dimensions: time domain resources, frequency domain resources, and preamble resources. Different random access resources may have different resources in all three dimensions, or they may have different resources in one or two dimensions.

[0174] Currently, when transmitting at least two first common signals using pure TDM, there is a one-to-one or one-to-many relationship between the resources occupied by the at least two first common signals and the random access resource set.

[0175] like Figure 8A As shown, the first common signal, taking SSB as an example, includes multiple random access resource sets in the resource pool used to transmit random access signals, such as random access resource set 1 to random access resource set 9.

[0176] Figure 8AIn this process, the second communication device transmits eight first common signals, namely SSB1 to SSB8, using pure TDM. Each first common signal can be associated with one or more different random access resource sets. For example, SSB1 is associated with random access resource set 1, SSB2 with random access resource set 2, SSB3 with random access resource set 3, SSB4 with random access resource set 4, SSB5 with random access resource set 5, SSB6 with random access resource set 6, SSB7 with random access resource set 7, and SSB8 with random access resource set 8. Additionally, SSB8 is also associated with random access resource set 9. Figure 8A In the relationships shown, SSB1 to SSB7 have a one-to-one relationship with random access resource sets 1 to 7, while SSB8 has a one-to-two relationship with random access resource sets 8 and 9. Of course, Figure 8A The example provided is just for illustration; in reality, it can be a one-to-one or one-to-many relationship.

[0177] For information regarding the many-to-one relationship between the resources occupied by at least two first common signals and at least one random access resource set, please refer to [reference needed]. Figure 8B and Figure 8C To understand.

[0178] like Figure 8B As shown, when the second communication device transmits eight first common signals using pure FDM, that is, SSB1 to SSB8 are transmitted simultaneously on different frequency domain resources; wherein, the resources occupied by each first common signal can be associated with the same random access resource set, which may include Figure 8A The resources occupied by SSB1 to SSB8 shown are all associated with random access resource set 4.

[0179] Figure 8B In this context, there is an 8-to-1 relationship between the resources occupied by the 8 first common signals and the random access resource set 4 for transmitting random signals. If the number of first common signals is N, then according to... Figure 8B If the signals are sent in the manner shown, then there is an N-to-one relationship between the resources occupied by the N first common signals and the set of random access resources for sending random access signals, where N is an integer greater than 1.

[0180] like Figure 8CAs shown, when the second communication device transmits eight first common signals using TFDM (TDM+FDM) mode, the transmission occurs at two separate times. Four of the first common signals, SSB1 to SSB4, are transmitted simultaneously using different frequency domain resources at the first time. The other four first common signals, SSB5 to SSB8, are transmitted simultaneously using different frequency domain resources at the second time. The resources occupied by SSB1 to SSB4 are associated with random access resource set 2, and there is a 4-to-1 association between the resources occupied by SSB1 to SSB4 and random access resource set 2. Similarly, the resources occupied by SSB5 to SSB8 are associated with random access resource set 7, and there is a 4-to-1 association between the resources occupied by SSB5 to SSB8 and random access resource set 7.

[0181] From the above Figure 8B and Figure 8C As can be seen from the presented scheme, the resources occupied by the first common signals transmitted at different times are associated with different random access resource sets; and / or, the resources occupied by at least two frequency division multiplexed first common signals transmitted at the same time are associated with the same random access resource set. For example, the resources occupied by SSB1 to SSB4 transmitted simultaneously are associated with the same random access resource set 2; the resources occupied by SSB5 to SSB8 transmitted simultaneously are associated with the same random access resource set 7; while SSB1 and SSB5 transmitted at different times are associated with different random access resource sets, namely, random access resource set 2 and random access resource set 7, respectively.

[0182] The relationship between the resources occupied by the first common signal and the resources occupied by the random access signal can be called the uplink correlation relationship, whereby... Figure 8B and Figure 8C The uplink correlation between the resources occupied by the first public signal and the random access resource set can be understood as the first uplink correlation. Figure 8A The relationship between the resources occupied by the first public signal and the resources occupied by the random access signal can be understood as the second uplink correlation relationship.

[0183] S702. The first communication device sends a random access signal according to the uplink association. Correspondingly, the second communication device receives the random access signal according to the uplink association.

[0184] In the solution provided in this application embodiment, there is a many-to-one association between the resources occupied by at least two first common signals and at least one random access resource set. In this way, when the first communication device sends a random access signal using a certain random access resource set, the second communication device can use the multiple receiving beams associated with the random access resource set to receive the random access signal, which can improve the strength and diversity gain of the random access signal.
