Description

Technical Field

[0001] This application relates to the field of communications, and in particular, to a communication method and apparatus. Background Art

[0002] Compared with 4G networks, the transmission bandwidth of 5G networks has increased sharply. At the same time, a larger peak-to-average power ratio (PAPR) has further reduced the efficiency of power amplifiers (PAs), which has caused a sharp increase in the transmission power consumption of 5G network base stations. At the same time, the number of transmission channels of the base station has increased sharply, which has also caused a sharp increase in the static power consumption of the system. In addition, due to the increase in the deployed frequency band of 5G networks and the reduction in the coverage range, the more intensive deployment of base stations has further increased the overall power consumption of the entire network.

[0003] Currently, the power consumption of a single 5G base station is generally 2 to 3 times that of a typical 4G base station. In the 4G era, the typical power consumption of a single remote radio unit (RRU) was 660W. By the 5G era, the typical power consumption of a single active antenna unit (AAU) has increased to 1400W. The relatively high energy consumption is not conducive to environmental protection and sustainable social development on the one hand, and on the other hand, it has caused huge electricity bills. In fact, one of the main reasons for the high power consumption of 5G networks is that they need to periodically send various public signals. Typical public signals include synchronization signal / PBCH block (SSB) and system information block 1 (SIB1), etc. On the one hand, the overhead of sending these public signals is relatively large, which will cause more dynamic power consumption to increase; on the other hand, due to the need to frequently send these public signals (for example, the typical SSB / SIB1 transmission period is 20ms, that is, the base station needs to send SSB / SIB1 every 20ms), it is difficult for the base station to enter a deeper sleep state (the startup of hardware / software requires a certain delay), resulting in a relatively large static power consumption overhead on the base station side.

[0004] For this reason, researchers have proposed that the SSB transmission mode can be dynamically adjusted by configuring two sets of SSB configurations. Further, how to enable the terminal to determine the configurations of different SSBs in the scenario of dual SSB (multi-SSB) configuration is an issue worthy of attention. Summary of the Invention

[0069] Figure 1 is a schematic diagram of the architecture of the communication system 1000 to which the embodiments of the present application are applied. As Figure 1 shown, the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 may further include the Internet 300. Among them, the radio access network 100 may include at least one radio access network device (such as Figure 1 110a and 110b in Figure 1among 120a - 120j). The terminal is connected to the radio access network device wirelessly, and the radio access network device is connected to the core network by wireless or wired means. The core network device and the radio access network device can be independent different physical devices, or the functions of the core network device and the logical functions of the radio access network device can be integrated on the same physical device, or the functions of part of the core network device and part of the radio access network device can be integrated on a physical device. Terminals can be connected to each other, and radio access network devices can be connected to each other by wired or wireless means. Figure 1 This is only a schematic diagram, and other network devices may also be included in this communication system. For example, wireless relay devices and wireless backhaul devices may also be included, which are not drawn in Figure 1 the figure.

[0070] The radio access network device can be abbreviated as a network device, and can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5G mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it can also be a module or unit that completes part of the functions of a base station. For example, it can be a central unit (CU) or a distributed unit (DU). Here, the CU completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete part or all of the functions of the physical layer. For specific descriptions of the above protocol layers, reference can be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). The radio access network device can be a macro base station (such as Figure 1 110a in Figure 1In 110b), it can also be a relay node, a donor node, etc. Embodiments of the present application do not limit the specific technologies and specific device forms adopted by the radio access network device. For ease of description, the following uses a base station as an example of the radio access network device for description.

[0071] The terminal device can also be referred to as a terminal, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely applied to 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, remote medical treatment, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. Embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device. For ease of description, the following uses a terminal as an example of the terminal device for description.

[0072] The base station and the terminal can be fixed or movable. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. Embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0073] The roles of the base station and the terminal can be relative. For example, Figure 1 the helicopter or drone 120i in can be configured as a mobile base station. For the terminals 120j that access the radio access network 100 through 120i, the drone 120i is a base station; but for the base station 110a, 120i is a terminal, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between base stations. At this time, relative to 110a, 120i is also a base station. Therefore, the base station and the terminal can both be uniformly referred to as communication devices. Figure 1 110a and 110b in can be referred to as communication devices with base station functions. Figure 1 120a - 120j in can be referred to as communication devices with terminal functions.

[0074] Communication can be carried out between a base station and a terminal, between base stations, and between terminals through licensed spectrum, through unlicensed spectrum, or simultaneously through licensed and unlicensed spectra; communication can be carried out through spectra below 6 gigahertz (GHz), through spectra above 6 GHz, or simultaneously using spectra below 6 GHz and above 6 GHz. Embodiments of this application do not limit the spectrum resources used for wireless communication.

[0075] In embodiments of this application, the functions of a base station can also be performed by a module (such as a chip) in the base station or by a control subsystem including base station functions. Here, the control subsystem including base station functions can be a control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of a terminal can also be performed by a module (such as a chip or a modem) in the terminal or by a device including terminal functions.

[0076] It can be understood that in embodiments of this application, the physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH) are only examples of a downlink data channel, a downlink control channel, an uplink control channel, and an uplink data channel respectively. In different systems and different scenarios, data channels and control channels may have different names, and embodiments of this application do not limit this.

[0077] Below, some terms in embodiments of this application are explained to facilitate understanding by those skilled in the art.

[0078] 1. Subcarrier (SC): In an orthogonal frequency division multiplexing (OFDM) system, the frequency domain resources are divided into several sub-resources, and each sub-resource in the frequency domain can be called a subcarrier. A subcarrier can also be understood as the smallest granularity of frequency domain resources.

[0079] 2. Sub-carrier space: In an OFDM system, it is the interval value between the center positions or peak positions of two adjacent sub-carriers in the frequency domain. For example, the sub-carrier space in the LTE system is 15 kHz, and the sub-carrier space in the NR system of 5G can be 15 kHz, 30 kHz, 60 kHz, 120 kHz, etc.

[0080] 3. SSB:

[0081] In the current communication network, the terminal mainly conducts cell search based on searching for SSB. SSB includes two parts, namely the synchronization signal (SS) and the physical broadcast channel (PBCH). And SS includes the primary synchronization signal (PSS) and the secondary synchronization signal (SSS). Therefore, it can also be considered that SSB includes three parts. Among them, the combination of SS and PBCH can be used to obtain the cell ID, downlink timing (for example, finding the reference point for downlink transmission, such as the frame boundary), and obtaining necessary system messages (for example, obtaining the time-frequency resource location of the PDCCH corresponding to SIB1, etc.).

[0082] The SSB of NR mainly has two functions:

[0083] 1) Cell synchronization and obtaining the master information block (MIB)

[0084] Among them, PSS and SSS will carry the physical cell identifier (PCI). The terminal obtains the PCI by detecting PSS and SSS. At the same time, the PBCH of SSB will carry the SSB index. Each SSB index corresponds to a transmission position. By detecting the SSB index and the detection time, downlink timing synchronization is completed.

[0085] 2) Wide beam training

[0086] An SSB pattern will contain multiple SSB Indexes. Different SSB indexes correspond to different base station transmission beams. The terminal can select the best SSB index by detecting SSB. At the same time, the terminal can also use multiple receiving beams to receive the same SSB index with different receiving beams to complete the receiving beam training on the terminal side.

[0087] Before the terminal detects the SSB, it does not know the specific time-frequency resource location of the SSB. That is to say, the terminal needs to blindly detect the location of the SSB. However, since the cell bandwidth in NR is very wide, if the terminal tries to detect the SSB at each frequency point, it will lead to a very slow access speed of the terminal. Therefore, the NR protocol specifically defines a synchronization raster, which has different sizes in different frequency bands, namely 1200 kHz, 1.44 MHz, and 17.28 MHz. That is to say, the terminal can try to detect the SSB one by one at intervals of the synchronization raster, thereby improving the speed of the terminal detecting the SSB. Exemplarily, in the initial access, the terminal will assume that the period for the base station to send the SSB is 20 ms. That is to say, if on a synchronization raster, if the terminal waits for 20 ms and does not detect the SSB, the terminal may continue to detect on other synchronization rasters.

[0088] The time-frequency resource structure of the SSB is as Figure 2 shown. The SSB contains 4 symbols that are continuous in the time domain and occupy 20 resource blocks (RBs) in the frequency domain, that is, 240 subcarriers.

[0089] The frequency-domain position of the SSB: The position of the SSB in the frequency domain is defined by the synchronization raster, as described above.

[0090] The time-domain position of the SSB: The time-domain position of the SSB is defined by the SSB pattern. An SSB pattern specifies the time-domain position of a group of continuous SSBs in a half-frame. Currently, 3GPP has defined 5 SSB patterns for the unshared spectrum, and each SSB pattern has its own applicable subcarrier detection SCS. However, generally only 1 - 2 SSB patterns are available for each band.

[0091] It can be understood that the SSB pattern is predefined by the protocol, and at the same time, there is a one-to-one mapping relationship between different SSB patterns and SCS and bands. Table 1 below shows an example of the relationship between the SSB pattern, SCS, and bands. It should be noted that Table 1 below intercepts part of the content specified in the existing protocol.

[0092] Table 1

[0093]

[0094] In Table 1 above, Case A, Case B, Case C, etc. are specific SSB patterns.

[0095] Taking Case A as an example, Case A has the following characteristics:

[0096] (1) Case A only supports SCS of 15KHz.

[0097] (2) According to Case A, the starting OFDM symbol index of SSB in a half-frame is {2, 8} + 14·n.

[0098] Among them, when the serving frequency is less than or equal to 3GHz, n = 0, 1, that is, SSB is sent in the first 2 time slots of a half-frame, and the starting OFDM symbol corresponding to SSB in each time slot is the 3rd / 9th. That is, there are a total of 4 transmission resources for SSB.

[0099] When the serving frequency is greater than 3GHz, n = 0, 1, 2, 3, that is, SSB is sent in the first 4 time slots of a half-frame, and the starting OFDM symbol corresponding to SSB in each time slot is the 3rd / 9th. That is, there are a total of 8 transmission resources for SSB.

[0100] When the terminal detects SSB, the terminal can determine the corresponding SSB pattern according to the SCS and the frequency band it is in. Further, the MIB in the SSB carries half-frame indication information and the system frame number (SFN). Correspondingly, after the terminal receives the SSB, the terminal can know the specific frame based on the SFN in the MIB, and know the specific half-frame based on the half-frame indication information in the MIB. Since there is a one-to-one mapping relationship between a specific SSB index and a fixed time-domain position in the SSB pattern, the terminal can also determine the time slot / OFDM symbol distribution in the half-frame based on the SSB index and the SSB pattern.

[0101] At the same time, after detecting the SSB, the terminal will further receive SIB1. Among them, SIB1 contains the actual transmission period of the SSB (for example, indicated by the ssb-PeriodicityServingCell field in SIB1) and the actually transmitted SSB beam, or the actual transmission situation of the SSB (for example, indicated by the ssb-PositionsInBurst field in SIB1). For example, the ssb-PositionsInBurst field can be used to indicate which SSB indexes' corresponding SSBs are sent, or indicate on which SSB transmission opportunities the SSB is sent. Based on the above information and the detected SSB pattern, the terminal can know the actual transmission configuration of the SSB (including the period, the SSB beams sent in each period, etc.).

[0102] As can be seen from the above, the terminal determines the transmission configuration of the SSB mainly in two steps: First, at the initial access, based on the predefined mapping relationship of SCS, frequency band, and SSB pattern (for example, Table 1), determine the SSB pattern (for example, Case A); Second, after receiving SIB1, determine the actually transmitted SSB pattern according to the periodic configuration of the SSB and the actual transmission beam configuration.

[0103] In the existing network, the period of the SSB is usually relatively frequent (for example, the typical period is 20 ms); at the same time, the SSB beams transmitted in each period are the same (there is only one SSB configuration and a corresponding ssb-PositionsInBurst parameter). Therefore, researchers propose that the SSB transmission mode can be dynamically adjusted by configuring two sets of SSB configurations.

[0104] For example, as Figure 3 shown, the base station configures a set of basic SSBs or long-period SSBs to ensure basic network access and measurement performance. The period of this SSB is usually long (for example, 160 ms) and the transmitted SSB beams are relatively complete. In addition, the base station also configures a set of short-period SSBs to serve the users covered by the base station on demand. Specifically: the transmission period of the short-period SSB can vary dynamically according to the load. For example, in a medium-light load scenario, the transmission period can be lengthened or its transmission pattern can be changed to reduce the network overhead of transmitting the SSB and reduce the power consumption of the base station. For example, the transmission pattern of the short-period SSB can vary dynamically according to the distribution of terminals. When the terminals are relatively concentrated, only the SSB beams in the direction determined according to the terminal distribution can be transmitted to reduce the network overhead of transmitting the SSB and reduce the power consumption.

[0105] However, if two sets of SSB configurations are introduced, the terminal may not be able to determine on which transmission resources each of the two sets of SSBs is transmitted. In particular, when the transmission configuration of short-period SSBs changes (including changes in the transmitted SSB beams or the period of SSBs), the terminal also cannot know which specific corresponding transmission resources have changed, which may in turn affect a series of SSB-related processes, including SSB-related measurements, transmissions mapped to SSBs, etc. Among them, SSB-related measurements may involve radio link monitoring (RLM), radio resource management (RRM), bidirectional forwarding detection (BFD), beam failure recovery (BFR), synchronization, automatic gain control (AGC), etc., and transmissions mapped to SSBs may involve the random access channel (RACH), Paging, SIB1, etc.

[0106] In this application, the common signal can refer to one of SSB, PSS, SSS, PBCH, or a combination of multiple of them, or other signals that can be used for the terminal to access the network. Among them, the period of the common signal can also be referred to as the transmission period of the common signal, or the sending period of the common signal, etc., and this application does not make any limitations in this regard. The system message can refer to SIB1, or other SIBs, SIBx (where x is a positive integer and not 1), system information (SI), etc. It can be understood that the following takes the common signal as SSB and the system message as SIB1 as an example for illustration, and it is not a limitation of this application. In the following content, the system message includes A, which can also be replaced with the system message indicating A, or the system message carrying A, etc., and this application does not make any limitations in this regard. Among them, A can be a specific parameter or a corresponding relationship, etc., and specific references can be found in the following relevant descriptions. In addition, it can be understood that the system message can also include other content in addition to the content involved below.

[0107] Based on the above network system architecture and the content of the above related technical introduction, several possible communication methods are provided in the embodiments of this application, and the execution entities of each communication method are introduced by taking the base station and the terminal as examples. For example, the base station can be the access network device 110a or the access network device 110b mentioned above Figure 1 The terminal can be the one mentioned above Figure 1Any one of the terminals 120 shown. In addition, it should be understood that the base station can also be replaced by a communication device with base station functions or a chip, unit, or module inside a communication device with base station functions. The terminal can also be replaced by a communication device with terminal functions or a chip, unit, or module inside a communication device with terminal functions.

[0108] Figure 4 Exemplarily shows a possible schematic flow diagram of a communication method provided by an embodiment of the present application. As Figure 4 shown, the method includes:

[0109] Step 400: The base station sends a system message, and correspondingly, the terminal receives the system message.

[0110] In a possible implementation manner, the base station can also send N of the M common signals. Correspondingly, the terminal can detect at least one of the N common signals. The terminal can receive the corresponding system message based on the detected common signal, where M is an integer greater than 1 and N is a positive integer less than or equal to M.

[0111] For example, the base station can send a first SSB and a second SSB, and the terminal can detect the first SSB, and then determine the time-frequency position of SIB1 based on the first SSB and detect SIB1 at this time-frequency position.

[0112] Step 410: The terminal determines the transmission resource configuration of the M common signals according to the system message, where M is an integer greater than 1.

[0113] It can be understood that the transmission resource configuration of the M common signals can also be described as the transmission configuration of the M common signals, or the configuration of the M common signals, or the time-domain configuration of the M common signals, etc. The present application does not limit this.

[0114] The following describes the specific process of the terminal determining the transmission resource configuration of the M common signals in combination with possible implementation manners of the system message.

[0115] Possible implementation manner 1:

[0116] The system message includes the periods of M - 1 common signals among the M common signals except the first common signal and / or the first offsets respectively corresponding to the M - 1 common signals, where the period and / or the first offset of the first common signal can be predefined or carried by the system message.

[0117] Exemplarily, the period of the first common signal may be predefined, and the first offset of the first common signal may be carried by the system message. That is to say, the protocol predefines the period of the first common signal, and the system message further includes the first offset of the first common signal. Or, the first offset of the first common signal may be predefined, and the period of the first common signal may be carried by the system message. That is to say, the protocol predefines the first offset of the first common signal, and the system message further includes the period of the first common signal. Or, the period and the first offset of the first common signal may be predefined. That is to say, the protocol predefines the period of the first common signal and the first offset of the first common signal. Or, the period and the first offset of the first common signal are carried by the system message. That is to say, the system message further includes the period of the first common signal and the first offset of the first common signal.

[0118] It can be understood that if the protocol predefines the period of the first common signal and the first offset of the first common signal, that is, the protocol predefines the transmission resource configuration of the first common signal. At this time, the terminal can determine the transmission resource configurations of the remaining M - 1 common signals among the M common signals according to the system message.

[0119] Wherein, the i-th common signal is any one of the M common signals. Taking the i-th common signal as an example, the first offset of the i-th common signal indicates the system frame in which the transmission resource of the i-th common signal is located within the period of the i-th common signal. Or described as, the first offset of the i-th common signal indicates the time domain unit in which the transmission resource of the i-th common signal is located within the period of the i-th common signal. Or, the first offset of the i-th common signal indicates the time domain position in which the transmission resource of the i-th common signal is located within the period of the i-th common signal.

[0120] Exemplarily, the period of the i-th common signal is X system frames, and the first offset of the i-th common signal is Y system frames. Wherein, X is a positive integer, and Y is an integer greater than or equal to 0 and less than X. That is to say, the i-th common signal will be transmitted in the (Y + 1)-th system frame among every X system frames. Or rather, the i-th common signal will be transmitted in the system frame with the system frame number Z, where Z mod X = Y, and Z is an integer greater than or equal to 0.

[0121] It can be understood that the period and the first offset of the i-th common signal can be configured in units of system frames, or in milliseconds (ms), or in other time units. This application does not make any limitations in this regard.

[0122] For example, the period of the i-th SSB is two system frames, and the first offset of the i-th SSB is one system frame. That is, the i-th SSB is transmitted in the second system frame of every two system frames. Or rather, the i-th SSB is transmitted in the system frame with the system frame number Z, where Z mod 2 = 1.

[0123] For another example, the period of the i-th SSB is 20 ms, and the first offset of the i-th SSB is 10 ms. That is, the i-th SSB is transmitted in the second 10-ms period of every 20 ms.

[0124] In addition, in a possible implementation, after detecting a common signal, the terminal can determine the SFN of the system frame where the common signal is located based on the common signal. Then, after receiving the system message, the terminal can determine the periods of the M common signals and the first offsets of the M common signals according to the system message, or the system message and predefined relevant content. Thus, the terminal can determine the period and the first offset of the detected common signal based on the obtained SFN, as well as the periods of the M common signals and the first offsets of the M common signals, that is, determine the transmission resource configuration of the detected common signal and the transmission resource configurations of the other M - 1 common signals. Among them, the detected common signal is one of the M common signals.

[0125] As a possible implementation, if M = 2, the M common signals include a first common signal and a second common signal. The system message can indicate the period and the first offset value of the second common signal. Among them, the period and the first offset of the first common signal can be predefined or can also be carried by the system message. It can be understood that in the above scenario, if the period and the first offset of the first common signal are predefined, the terminal determines the period and the first offset value of the second common signal according to the system message, that is, determines the transmission resource configuration of one common signal. Exemplarily, the period of the first common signal is greater than the period of the second common signal, or the period of the first common signal is less than the period of the second common signal.

[0126] For example, as Figure 5As shown, M = 2, and the two common signals are the first SSB and the second SSB respectively. Exemplarily, the first SSB is a long-period SSB, and the second SSB is a short-period SSB. The period and the first offset of the first SSB are predefined, and the period and the first offset of the second SSB are carried by SIB1. Among them, the period of the first SSB is 8 system frames (or 80 ms), and the first offset of the first SSB is 2 system frames (or 20 ms). That is, the first SSB is transmitted in the 3rd system frame of every 8 system frames. Or rather, the first SSB is transmitted in the system frame with the system frame number Z1, where Z1 mod 8 = 2. The period of the second SSB is 2 system frames, the first offset of the second SSB is 1 system frame, and the second SSB is transmitted in the system frame with the system frame number Z2, where Z2 mod 2 = 1.

[0127] Furthermore, after detecting the SSB, the terminal can obtain the SFN where the SSB is located based on the MIB in the SSB. After receiving SIB1, the terminal determines the period and the first offset of the second SSB according to SIB1, and then, based on the obtained SFN, as well as the predefined period and the first offset of the first SSB and the period and the first offset of the second SSB carried by SIB1, determines whether the detected SSB is the first SSB or the second SBB. For example, if the SFN obtained by the terminal is 21, and it is determined that 21 satisfies Z2 mod 2 = 1, then it is further determined that the detected SSB is the second SSB. Therefore, the terminal can determine the transmission resource configuration corresponding to the detected SSB, and thus can also determine the transmission resource configuration corresponding to the undetected SSB.

[0128] With the above implementation method, the terminal can obtain the periods and the first offsets of M common signals, and thus can distinguish different common signals through different system frames, and detect the corresponding common signals on the corresponding transmission resources according to the transmission resource configurations of the M common signals.

[0129] Possible implementation method 2:

[0130] In the scenario where M = 2, the M common signals include the first common signal and the second common signal.

[0131] Example 1, the system message includes the period of the first common signal. The half-frame corresponding to the transmission resource of the second common signal can be predefined, and the period of the second common signal can be predefined or carried by the system message.

[0132] For example, the protocol predefines the half-frame and the period of the second common signal, and the system message includes the period of the first common signal.

[0133] It can be understood that if the half-frame of the second common signal is pre-defined by the protocol, the period of the second common signal, that is, the transmission resource configuration of the second common signal pre-defined by the protocol, at this time, the terminal can determine the transmission resource configuration of the first common signal according to the system message.

[0134] For another example, the half-frame of the second common signal is pre-defined by the protocol, and the system message includes the period of the first common signal and the period of the second common signal.

[0135] It can be understood that the half-frame corresponding to the transmission resource of the second common signal can be pre-defined, or it can be replaced by the half-frame corresponding to the transmission resource of the first common signal being pre-defined, or both the half-frame corresponding to the transmission resource of the first common signal and the half-frame corresponding to the transmission resource of the second common signal are pre-defined. That is to say, if the half-frame corresponding to the transmission resource of one of the two common signals is pre-defined, that is, the half-frames corresponding to the transmission resources of the two common signals are pre-defined respectively, that is, both the half-frame corresponding to the transmission resource of the first common signal and the half-frame corresponding to the transmission resource of the second common signal are pre-defined. It can also be understood that if the half-frame corresponding to the transmission resource of one common signal is pre-defined, then the half-frame corresponding to the transmission resource of the other common signal is also determined, and at this time, it may not be necessary to notify through the system message.

[0136] Example 2, the system message includes the period of the first common signal and the half-frame corresponding to the transmission resource of the first common signal, and the period of the second common signal can be pre-defined or carried by the system message.

[0137] For example, the protocol pre-defines the period of the second common signal, and the system message includes the period of the first common signal and the half-frame corresponding to the transmission resource of the first common signal.

[0138] For another example, the system message includes the period of the first common signal, the half-frame corresponding to the transmission resource of the first common signal, and the period of the second common signal.

[0139] Among them, the system message can include the half-frame corresponding to the transmission resource of the first common signal, or it can be replaced by the system message including the half-frame corresponding to the transmission resource of the second common signal, or the system message can include the half-frame corresponding to the transmission resource of the first common signal and the half-frame corresponding to the transmission resource of the second common signal.

[0140] In the above two examples, the half-frame corresponding to the transmission resource of the first common signal is different from the half-frame corresponding to the transmission resource of the second common signal. The half-frame corresponding to the transmission resource of the first common signal can be understood as the transmission resource of the first common signal being in the first half-frame or the second half-frame. The half-frame corresponding to the transmission resource of the second common signal can be understood as the transmission resource of the second common signal being in the first half-frame or the second half-frame.

[0141] In addition, the first common signal may carry half-frame indication information for indicating whether the transmission resources of the first common signal are in the first half-frame or the second half-frame. The second common signal may also carry half-frame indication information for indicating whether the transmission resources of the second common signal are in the first half-frame or the second half-frame. For example, the half-frame indication information occupies 1 bit. When the 1 bit is set to 0, it represents the first half-frame; when the 1 bit is set to 1, it represents the second half-frame. Alternatively, when the 1 bit is set to 0, it represents the second half-frame; when the 1 bit is set to 1, it represents the first half-frame. This application does not make any limitation in this regard.

[0142] Further, in a possible implementation, after detecting a common signal, the terminal may determine the half-frame corresponding to the transmission resources of the common signal based on the half-frame indication information in the common signal. If the half-frame corresponding to the transmission resources of one (or two) common signals is predefined (refer to the above Example 1), the terminal may determine which common signal the detected common signal is according to the half-frame indication information and the predefined half-frame corresponding to the transmission resources of one (or two) common signals. If the half-frame corresponding to the transmission resources of any common signal is not predefined, but the half-frames corresponding to the transmission resources of the two common signals are determined through system information (refer to the above Example 1), the terminal may determine which common signal the detected common signal is according to the half-frame indication information and the half-frames corresponding to the transmission resources of the two common signals determined through system information. Therefore, the terminal may determine the transmission resource configuration of the detected common signal, and further may also determine the transmission resource configuration of the other common signal. Herein, the common signal detected by the terminal is one of the two common signals.

[0143] For example, as Figure 6 shown, M = 2, and the two common signals are the first SSB and the second SSB respectively. Exemplarily, the first SSB is a long-period SSB, and the second SSB is a short-period SSB. The period of the first SSB and the half-frame corresponding to the transmission resources of the first SSB are predefined. The period of the second SSB is carried by SIB1. Herein, the period of the first SSB is 8 system frames (or 80 ms), and the half-frame corresponding to the transmission resources of the first SSB is the first half-frame. The period of the second SSB is 2 system frames (or 20 ms), and the half-frame corresponding to the transmission resources of the second SSB is the second half-frame. Here, the first SSB and the second SSB may exist in the same system frame, which is only for illustration and not a limitation of this application. In addition, the transmission resources of the first SSB and the transmission resources of the second SSB may also exist in different system frames, or always exist in different system frames.

[0144] In addition, the first SSB includes half-frame indication information, which indicates that the half-frame corresponding to the transmission resource of the first SSB is the first half-frame, and this half-frame indication information is carried by the MIB in the first SSB. The second SSB includes half-frame indication information, which indicates that the half-frame corresponding to the transmission resource of the second SSB is the second half-frame, and this half-frame indication information is carried by the MIB in the second SSB.

[0145] Furthermore, after detecting the SSB, the terminal can know the half-frame where the transmission resource of the detected SSB is located based on the half-frame indication information in the detected SSB. For example, if the half-frame where the SSB is located is the second half-frame, and since it is predefined that the half-frame corresponding to the transmission resource of the first SSB is the first half-frame, the terminal can determine that the detected SSB is the second SSB. Further, the terminal receives SIB1, and SIB1 includes the period of the second SSB, so that the terminal device determines the transmission resource configuration of the second SSB according to the period of the second SSB and the fact that the half-frame corresponding to the transmission resource of the second SSB is the second half-frame. In addition, the terminal can also determine the transmission resource configuration of the first SSB based on the fact that the half-frame corresponding to the transmission resource of the first SSB is the first half-frame and the period of the first SSB.

[0146] By adopting the above implementation method, the terminal can know the half-frames where the transmission resources of the first common signal and the second common signal are located respectively, and further can distinguish different common signals through different half-frames, and detect the corresponding common signals on the corresponding transmission resources according to the transmission resource configurations of the two common signals.

[0147] Possible implementation method 3:

[0148] In the scenario where M = 2, the M common signals include a first common signal and a second common signal.

[0149] The system message includes a first period. The first offset and / or the period of the first common signal is predefined or carried by the system message.

[0150] Exemplarily, the period of the first common signal can be predefined, and the first offset can be carried by the system message, that is, the protocol predefines the period of the first common signal, and the system message also includes the first offset. Or, the first offset can be predefined, and the period of the first common signal can be carried by the system message, that is, the protocol predefines the first offset, and the system message also includes the period of the first common signal. Or, the first offset and the period of the first common signal can be predefined, that is, the protocol predefines the first offset and the period of the first common signal. Or, the first offset and the period of the first common signal are carried by the system message, that is, the system message also includes the first offset and the period of the first common signal.

[0151] It can be understood that if the protocol predefines the first offset and the period of the first common signal, that is, the protocol predefines the transmission resource configuration of the first common signal. At this time, the terminal can determine the transmission resource configuration of the second common signal according to the system message.

[0152] Among them, the first period and the first offset are used to determine the first transmission resource.

[0153] It can be understood that the first transmission resource determined by the first period and the first offset includes the transmission resource of the first common signal and the transmission resource of the second common signal. Or it can be understood that the terminal can detect the first common signal according to the first transmission resource, and can also detect the second common signal. Or it can be described as that the common signal detected by the terminal according to the first transmission resource is the first common signal or the second common signal. It can also be understood that the first period is the period during which the terminal can detect the common signal, the first offset is the system frame in which the common signal that the terminal can detect is located in the first period, and the common signal that the terminal can detect is the first common signal or the second common signal.

[0154] Among them, the first offset can be configured in units of system frames, or in milliseconds (ms), or in other time units. This application does not make any limitations in this regard.

[0155] Among them, the transmission resource of the first common signal can be determined based on the period of the first common signal and the first offset. That is to say, the transmission resource that satisfies the period of the first common signal and the first offset in the first transmission resource is the transmission resource of the first common signal. And the transmission resource in the first transmission resource other than the transmission resource of the first common signal is the transmission resource of the second common signal. That is, the remaining transmission resource in the first transmission resource after removing the transmission resource of the first common signal is the transmission resource of the second common signal.

[0156] In addition, in a possible implementation manner, after the terminal detects the common signal, it can determine the SFN of the system frame where the common signal is located based on the common signal. Then, after receiving the system message, the terminal can determine the first period, the first offset, and the period of the first common signal according to the system message, or the system message and the predefined relevant content, that is, determine the transmission resource configuration of the first common signal and the transmission resource configuration of the second common signal. Thus, the terminal can determine which common signal the detected common signal is according to the obtained SFN, as well as the first period, the first offset, and the period of the first common signal, that is, determine the transmission resource configuration of the detected common signal and the transmission resource configuration of the other common signal. Among them, the detected common signal is one of the two common signals.

[0157] For example, as Figure 7As shown, M = 2, and the two common signals are the first SSB and the second SSB respectively. Exemplarily, the first period can be carried by SIB1, and the period and the first offset of the first SSB can be predefined. The first period is 2 system frames (or 20 ms), and the first offset is 1 system frame (or 10 ms). The period of the first SSB is 8 system frames (or 80 ms). That is, the terminal can detect the first SSB or the second SSB in the second system frame of every 2 system frames. Or rather, the terminal can detect the first SSB or the second SSB in the system frame with the system frame number Q1, where Q1 mod 2 = 1. From the period of the first SSB being 8 system frames and the first offset, it can be known that the first SSB is transmitted in the second system frame of every 8 system frames. Or rather, the first SSB is transmitted in the system frame with the system frame number Q2, where Q2 mod 8 = 1. Therefore, the second SSB is transmitted in the system frame with the system frame number Q3, where Q3 mod 2 = 1 and Q3 mod 8 ≠ 1.

[0158] Furthermore, after detecting the SSB, the terminal can obtain the SFN where the SSB is located based on the MIB in the SSB. After receiving SIB1, the terminal determines the first period according to SIB1, and then judges whether the detected SSB is the first SSB or the second SSB based on the obtained SFN, the predefined period of the first SSB, and the first offset. For example, if the obtained SFN of the terminal is 21, and it is determined that 21 satisfies Q3 mod 2 = 1 and Q3 mod 8 ≠ 1, then it is further determined that the detected SSB is the second SSB. Therefore, the terminal can determine the transmission resource configuration corresponding to the detected SSB, and thus can also determine the transmission resource configuration corresponding to the undetected SSB.

[0159] With the above implementation method, the terminal can obtain the distribution of the two common signals within the first period, and further can distinguish different common signals through different system frames, and detect the corresponding common signals on the corresponding transmission resources according to the transmission resource configurations of the two common signals.

[0160] Possible implementation method 4:

[0161] The system message includes the periods of M - 1 common signals among the M common signals except the first common signal, and the corresponding relationship between the periods of the M - 1 common signals and the transmission patterns of the M - 1 common signals. The period and / or the transmission pattern of the first common signal is predefined or carried by the system message.

[0162] For example, the system message includes the periods of M - 1 common signals among the M common signals excluding the first common signal, and the correspondence between the periods of the M - 1 common signals and the transmission patterns of the M - 1 common signals. The system message further includes the period of the first common signal, and the correspondence between the period of the first common signal and the transmission pattern of the first common signal.

[0163] For another example, the system message includes the periods of M - 1 common signals among the M common signals excluding the first common signal, and the correspondence between the periods of the M - 1 common signals and the transmission patterns of the M - 1 common signals. The protocol pre - defines the period of the first common signal, and the correspondence between the period of the first common signal and the transmission pattern of the first common signal.

[0164] It can be understood that if the protocol pre - defines the period of the first common signal, and the correspondence between the period of the first common signal and the transmission pattern of the first common signal, that is, the protocol pre - defines the transmission resource configuration of the first common signal. At this time, the terminal can determine the transmission resource configurations of the remaining M - 1 common signals among the M common signals according to the system message.

[0165] For another example, the system message includes the periods of M - 1 common signals among the M common signals excluding the first common signal, and the correspondence between the periods of the M - 1 common signals and the transmission patterns of the M - 1 common signals. The system message further includes the period of the first common signal, and the protocol pre - defines the correspondence between the period of the first common signal and the transmission pattern of the first common signal.

[0166] For another example, the system message includes the periods of M - 1 common signals among the M common signals excluding the first common signal, and the correspondence between the periods of the M - 1 common signals and the transmission patterns of the M - 1 common signals. The system message further includes the correspondence between the period of the first common signal and the transmission pattern of the first common signal, and the protocol pre - defines the period of the first common signal.

[0167] Exemplarily, the transmission pattern of the common signal can be Case A, or Case B, or Case C, etc., or a newly - defined transmission pattern by the protocol. Among them, the transmission patterns of multiple common signals can be pre - defined. For example, the transmission pattern of the common signal can be understood as the SSB pattern.

[0168] Exemplarily, the correspondence between the periods of M-1 common signals and the transmission patterns of the M-1 common signals can also be described as the mapping relationship between the periods of the M-1 common signals and the transmission patterns of the M-1 common signals, or, the periods of the M-1 common signals are in one-to-one mapping with the transmission patterns of the M-1 common signals. Among them, the correspondence between the periods of the M-1 common signals and the transmission patterns of the M-1 common signals can be carried by the same field.

[0169] In addition, in a possible design, the terminal receives a third common signal, and the third common signal is one of the M common signals. Among them, the third common signal carries first indication information, and the first indication information indicates the transmission pattern of the third common signal. For example, the first indication information is carried by the MIB in the SSB. Further, the terminal can determine the period of the third common signal according to the transmission pattern of the third common signal and the correspondence between the periods of the M common signals and the transmission patterns of the M common signals. It can be understood that the terminal can obtain the correspondence between the periods of the M common signals and the transmission patterns of the M common signals through system messages, or system messages and predefined related content.

[0170] It can be understood that in possible implementation manner 4, the transmission pattern of the common signal corresponding to each frequency band and SCS can be one or more.

[0171] Exemplarily, the transmission patterns of the M common signals are different from each other. Furthermore, the transmission patterns of the M common signals can make the time-domain resources corresponding to the M common signals non-overlapping, or it can be understood that the time-domain resources corresponding to the M common signals are completely orthogonal, and the time-domain resources corresponding to the M common signals are different.

[0172] For example, as Figure 8 shown, M = 2, and the two common signals are the first SSB and the second SSB respectively. Exemplarily, the first SSB is a long-period SSB, the second SSB is a short-period SSB, the period of the first SSB is 8 system frames (or 80 ms), and the period of the first SSB is predefined. The period of the second SSB is 4 system frames (or 40 ms). SIB1 can include the period of the second SSB, and third indication information, where the third indication information indicates the correspondence between the period of the first SSB and the transmission pattern of the first SSB, and the correspondence between the period of the second SSB and the transmission pattern of the second SSB. It can be understood that the first SSB and the second SSB may exist in the same system frame, or may also exist in different system frames, or always exist in different system frames, and this application does not make any limitations on this.

[0173] As shown in Table 2 below is the specific content indicated by the third indication information. The time-domain resources corresponding to Case X and the time-domain resources corresponding to Case Y do not overlap.

[0174] Table 2

[0175] SSB Period Transmission Pattern First SSB 80 ms Case X Second SSB 40 ms Case Y

[0176] Further, after detecting the SSB, the terminal can obtain the transmission pattern corresponding to the SSB based on the MIB in the SSB. For example, the transmission pattern corresponding to the SSB is Case Y. After receiving SIB1, the terminal determines the period of the second SSB and Table 2 according to SIB1, and then determines that the detected SSB is the second SSB and the period of the detected SSB is 40 ms according to Table 2. Therefore, the terminal can determine the transmission resource configuration corresponding to the detected SSB, and can also determine the transmission resource configuration corresponding to the undetected SSB.

[0177] By adopting the above implementation method, the terminal can obtain the correspondence between the periods of M common signals and the transmission patterns of the M common signals, and further can distinguish different common signals through different transmission patterns, and detect corresponding common signals on corresponding transmission resources according to the transmission resource configurations of the M common signals.

[0178] Possible implementation method 5:

[0179] The system message includes the periods of M - 1 common signals among the M common signals except the first common signal, and the correspondence between the periods of the M - 1 common signals and the second offsets of the M - 1 common signals. The period and / or the second offset of the first common signal is predefined or carried by the system message.

[0180] For example, the system message includes the periods of M - 1 common signals among the M common signals except the first common signal, the correspondence between the periods of the M - 1 common signals and the second offsets of the M - 1 common signals, the period of the first common signal, and the correspondence between the period of the first common signal and the second offset of the first common signal.

[0181] Another example is that the system message includes the periods of M - 1 common signals among the M common signals except the first common signal, the correspondence between the periods of the M - 1 common signals and the second offsets of the M - 1 common signals, and the protocol defines the period of the first common signal and the correspondence between the period of the first common signal and the second offset of the first common signal.

[0182] It can be understood that if the protocol predefines the correspondence relationship between the period of the first common signal, the period of the first common signal, and the second offset of the first common signal, that is, the protocol predefines the transmission resource configuration of the first common signal. At this time, the terminal can determine the transmission resource configurations of the remaining M-1 common signals among the M common signals according to the system message.

[0183] For another example, the system message includes the periods of the M-1 common signals among the M common signals except the first common signal, and the correspondence relationship between the periods of the M-1 common signals and the second offsets of the M-1 common signals. The protocol defines the period of the first common signal, and the system message further includes the correspondence relationship between the period of the first common signal and the second offset of the first common signal.

[0184] For another example, the system message includes the periods of the M-1 common signals among the M common signals except the first common signal, and the correspondence relationship between the periods of the M-1 common signals and the second offsets of the M-1 common signals. The system message further includes the period of the first common signal, and the protocol predefines the correspondence relationship between the period of the first common signal and the second offset of the first common signal.

[0185] Wherein, the i-th common signal is any one of the M common signals. Taking the i-th common signal as an example, the second offset of the i-th common signal indicates the offset of the transmission resource of the i-th common signal relative to the transmission resource of the second common signal. The transmission resource of the second common signal is determined based on a predefined transmission pattern. In addition, the second common signal can also be referred to as a reference common signal or a reference common signal, etc. The present application does not make any limitations in this regard.

[0186] Wherein, the second offset can be configured in units of time slots or symbols, or in units of milliseconds (ms), or in other time units. The present application does not make any limitations in this regard.

[0187] In a possible implementation manner, since there is a one-to-one mapping relationship between different predefined transmission patterns, SCS, and frequency bands, when the SCS and frequency band are determined, the predefined transmission pattern is uniquely determined, and the transmission resource of the second common information is determined based on the uniquely determined predefined transmission pattern. For example, referring to Table 1 above, the frequency band is n1, the SCS is 15KHz, and the SSBPattern is Case A, that is, the transmission pattern of the second common information is Case A, and the transmission resource of the second common information is determined based on Case A.

[0188] In a possible implementation manner, the base station can predefine a transmission pattern for the second common signal. Here, the transmission pattern can be Case A, or Case B, or Case C, etc., or a transmission pattern newly defined by the protocol. The present application does not make any limitations in this regard.

[0189] It should be noted that the second common signal may or may not belong to the M common signals. If the second common signal belongs to the M common signals, the base station may or may not send the second common signal, and this application does not make any limitation in this regard.

[0190] Exemplarily, the correspondence between the periods of the M-1 common signals and the second offsets of the M-1 common signals can also be described as the mapping relationship between the periods of the M-1 common signals and the second offsets of the M-1 common signals, or the one-to-one mapping between the periods of the M-1 common signals and the second offsets of the M-1 common signals. Among them, the correspondence between the periods of the M-1 common signals and the second offsets of the M-1 common signals can be carried by the same field.

[0191] Exemplarily, the second offsets of the M common signals are different from each other. Furthermore, the second offsets of the M common signals can make the time-domain resources corresponding to the M common signals non-overlapping, or it can be understood that the time-domain resources corresponding to the M common signals are completely orthogonal, and the time-domain resources corresponding to the M common signals are different.

[0192] In addition, in a possible design, the terminal receives a third common signal, and the third common signal is one of the M common signals. Among them, the third common signal carries second indication information, and the second indication information indicates the second offset of the third common signal. For example, the second indication information is carried by the MIB in the SSB. Further, the terminal can determine the period of the third common signal according to the second offset of the third common signal and the correspondence between the periods of the M common signals and the second offsets of the M common signals. It can be understood that the terminal can obtain the correspondence between the periods of the M common signals and the second offsets of the M common signals through system messages, or system messages and predefined relevant content.

[0193] For example, as Figure 9 shown, M = 2, and the two common signals are the first SSB and the second SSB respectively. Exemplarily, the first SSB is a long-period SSB, the second SSB is a short-period SSB, the period of the first SSB is 8 system frames (or 80 ms), and the period of the first SSB is predefined. The period of the second SSB is 4 system frames (or 40 ms). SIB1 may include the period of the second SSB, and the fourth indication information, the third indication information indicates the correspondence between the period of the first SSB and the second offset of the first SSB, and the correspondence between the period of the second SSB and the second offset of the second SSB. It can be understood that the first SSB and the second SSB may exist in the same system frame, or may also exist in different system frames, or always exist in different system frames, and this application does not make any limitation in this regard.

[0194] As shown in Table 3 below, the specific content indicated by the fourth indication information is as follows.

[0195] Table 3

[0196] SSB Period Second Offset First SSB 80 ms 0 OFDM Symbols Second SSB 40 ms 1 OFDM Symbol

[0197] Further, after detecting the SSB, the terminal can obtain the second offset corresponding to the SSB based on the MIB in the SSB. For example, the second offset corresponding to the SSB is 1 OFDM symbol. After receiving SIB1, the terminal determines the period of the second SSB and Table 3 according to SIB1, and then determines that the detected SSB is the second SSB and the period of the detected SSB is 40 ms according to Table 3. Therefore, the terminal can determine the transmission resource configuration corresponding to the detected SSB, and can also determine the transmission resource configuration corresponding to the undetected SSB.

[0198] By adopting the above implementation method, the terminal can obtain the correspondence between the periods of M common signals and the second offsets of the M common signals, and further can distinguish different common signals through different second offsets, and detect corresponding common signals on corresponding transmission resources according to the transmission resource configurations of the M common signals.

[0199] In addition, in a possible implementation, the system message can also indicate the actual transmission situation of each of the M common signals. Exemplarily, the i-th common signal is any one of the M common signals. Taking the i-th common signal as an example, the system message also indicates the index of the actually transmitted common signal corresponding to the i-th common signal. For example, it can be indicated by the ssb-PositionsInBurst field corresponding to the i-th common signal in the system message.

[0200] In another possible implementation, the system message can also indicate the actual transmission situation of each of the M-1 common signals. Exemplarily, the i-th common signal is any one of the M-1 common signals. Taking the i-th common signal as an example, the system message also indicates the index of the actually transmitted common signal corresponding to the i-th common signal. For example, it can be indicated by the ssb-PositionsInBurst field corresponding to the i-th common signal in the system message. Among them, the transmission situation of the first common signal (for example, the index of the transmitted common signal corresponding to the i-th common signal) can be predefined or indicated by the system message. That is to say, the system message can also indicate the transmission situation of the first common signal, or the protocol predefines the transmission situation of the first common signal.
