[0034] The technical solutions in the present disclosure will be described clearly and completely below with reference to the drawings in the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present disclosure.

[0035] It should be noted that in the present disclosure, the words such as “exemplarily” or “for example” are used to represent as an example, illustration or description. Any embodiment or design scheme described as “exemplarily” or “for example” in the present disclosure should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. In fact, the words such as “exemplarily” or “for example” are intended to present the related concept by way of example.

[0036] Hereinafter, the terms “first”, “second”, and the like are used only for descriptive purposes, and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with “first”, “second”, and the like can explicitly or implicitly include one or more of the features.

[0037] In the description of the present disclosure, unless otherwise specified, “ / ” means “or”, for example, A / B can mean A or B. “And / or” in this document is only a description of the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can mean: only A, only B, and A and B. In addition, “at least one” means one or more, and “multiple” means two or more.

[0038] As in the background, when performing multi-level synchronization signal block (SSB) transmission, the base station side needs to broadcast the configuration of all SSBs of all cells to all UEs. In this way, the transmission frequency and power of the base station side are high, and unnecessary signal transmission is generated, and the energy consumption is high. Correspondingly, the terminal side needs to receive and process a large amount of information, which has high computational complexity and long processing time, high energy consumption and low resource utilization.

[0039] To solve the above technical problems, the embodiments of the present disclosure provide an information transmission method, and the idea is that a first node receives one or more synchronization signal block configurations sent by a second node, and performs synchronization signal block detection based on the one or more synchronization signal block configurations. It can be understood that the embodiments of the present disclosure can first receive one or more synchronization information configurations (for example, general or preliminary synchronization information configurations), and then receive more specific synchronization information configurations as needed. In this way, the information processing amount in the initial access stage can be reduced, the resource utilization efficiency can be improved, the calculation complexity of the UE in the signal search and synchronization stage can be reduced, the processing time can be reduced, and the energy consumption can be reduced.

[0040] The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, 5G new radio (NR) mobile communication networks, future mobile communication networks, or various communication fusion systems, and the embodiments of the present disclosure are not limited thereto.

[0041] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G, and future mobile communication networks) in the embodiments of the present disclosure can at least include a first communication node and a second communication node. It should be understood that in the present example, the first communication node can be a terminal side device (including but not limited to a terminal device) in the uplink, and the second communication node can also be a network side device (including but not limited to a base station). Of course, in the downlink, the first communication node can also be a network side device, and the second communication node can be a terminal side device. In the case of device-to-device communication between the two communication nodes, the first communication node and the second communication node can both be base stations or terminal devices. The first communication node and the second communication node can be referred to as the first node and the second node, respectively.

[0042] Exemplarily, taking the first communication node as a terminal device and the second communication node as a base station as an example, FIG. 1 shows a network architecture schematic diagram of a mobile communication network provided by the embodiments of the present disclosure. As shown in FIG. 1, the mobile communication network includes a terminal device 110 and a base station 120.

[0043] The terminal device 110 can be a device with wireless transceiver function. The terminal device 110 can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; the terminal device 110 can also be deployed on the water surface (such as ships, etc.); the terminal device 110 can also be deployed in the air (such as airplanes, balloons and satellites, etc.). For example, the terminal device 110 can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal device can also be referred to as a user, a UE, an access terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent or a UE apparatus, etc. The embodiments of the present disclosure do not limit this.

[0044] In some embodiments, the base station 120 is configured to provide wireless access services for a plurality of UEs. For example, a base station provides a service area (i.e., a service coverage area, also referred to as a cell). A UE entering the service area can communicate with the base station 120 through wireless signals to receive wireless access services provided by the base station 120.

[0045] In some embodiments, the base station 120 can be a base station in long term evolution (LTE), long term evolution advanced (LTE-A) or evolved node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote extension, reconfigurable intelligent surface (RIS), routers, wireless fidelity (WIFI) devices, and various network side devices.

[0046] In some embodiments, as shown in FIG. 2, the cell types provided by the base station 120 include super cells and micro cells.

[0047] In some embodiments, as shown in FIG. 3, the effective area provided by the base station 120 includes multiple cells.

[0048] It should be noted that FIG. 1 is only an exemplary framework diagram, the number of devices included in FIG. 1, and the names of various devices are not limited, and in addition to the devices shown in FIG. 1, the communication system can also include other devices, such as core network devices.

[0049] It can be understood that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0050] The information transmission method provided by the embodiments of the present disclosure will be described below.

[0051] Some embodiments of the present disclosure provide an information transmission method, as shown in FIG. 4, the method includes the following steps:

[0052] S201, the second node sends one or more synchronization signal block configurations to the first node; correspondingly, the first node receives one or more synchronization signal block configurations.

[0053] The one or more synchronization signal block configurations are determined by the second node.

[0054] S202, the first node detects the synchronization signal block based on the one or more synchronization signal block configurations.

[0055] It can be understood that based on the information transmission method provided by the embodiments of the present disclosure, the first node receives one or more synchronization signal block configurations sent by the second node; and detects the synchronization signal block based on the one or more synchronization signal block configurations. In this way, the first node can first receive one or more synchronization information configurations (for example, general, preliminary or simplified synchronization information configurations), and then receive more specific synchronization information configurations as needed. In this way, the information processing amount in the initial access stage can be reduced, the resource utilization efficiency can be improved, the calculation complexity of the UE in the signal search and synchronization stage can be reduced, thereby reducing the processing time and reducing the energy consumption. In the embodiments of the present disclosure, the technology used is not limited to reducing the energy consumption of the network side.

[0060] Next, first, one or more synchronization signal block configurations are described:

[0061] In some embodiments, the one or more synchronization signal block configurations include at least one of the following types:

[0062] The first synchronization signal block configuration;

[0063] The second synchronization signal block configuration;

[0064] The third synchronization signal block configuration;

[0065] The fourth synchronization signal block configuration.

[0066] One third synchronization signal block corresponds to one or more fourth synchronization signal blocks.

[0067] As a possible implementation, the above step S201 can be implemented as: the second node sends (or configures) one or more synchronization signal block configurations of different uses (or types) to the first node; accordingly, the first node receives one or more types of synchronization signal block configurations.

[0068] In some embodiments, the use of the first synchronization signal block includes at least one of the following:

[0069] The synchronization signal block for channel quality measurement;

[0070] The synchronization signal block used by the node in the idle state;

[0071] The synchronization signal block suitable for the first bandwidth.

[0072] In some embodiments, the node in the idle state includes a first node in an idle state and a first node in an inactive state.

[0073] In some embodiments, the configuration information of the synchronization signal block used by the node in the idle state is included in a system information block 1 (SIB1).

[0074] Exemplarily, the synchronization signal block used by the node in the idle state is fixedly transmitted in the cell, and the first node performs initial access and synchronization by detecting the synchronization signal block used by the node in the idle state.

[0075] Exemplarily, the synchronization signal block used by the node in the idle state is periodically transmitted.

[0076] In some embodiments, the use of the second synchronization signal block includes at least one of the following:

[0077] The synchronization signal block for area access;

[0078] The synchronization signal block used by the node in the connected state;

[0079] The synchronization signal block suitable for a second bandwidth, the second bandwidth being greater than the first bandwidth.

[0080] Exemplarily, the first bandwidth can be a narrow bandwidth, and the second bandwidth can be a wide bandwidth.

[0081] In some embodiments, the configuration information of the synchronization signal block used by the node in the connected state is included in a radio resource control (RRC).

[0082] Exemplarily, the synchronization signal block used by the node in the connected state is triggered transmission. Exemplarily, the synchronization signal block used by the node in the connected state can be triggered by downlink control information (DCI) signaling or media access control control element (MAC CE) signaling.

[0083] In some embodiments, the synchronization signal block configuration used by the node in the connected state includes one or more SSB burst sets. Exemplarily, the plurality of SSB burst sets are transmitted by a predefined period. Exemplarily, the plurality of SSB burst sets are transmitted continuously in the time domain.

[0084] In some embodiments, the pattern of the first synchronization signal block and the pattern of the second synchronization signal block are different.

[0085] As a possible implementation, the pattern of the first synchronization signal block and the pattern of the second synchronization signal block are different including at least one of the following:

[0086] The transmission density of the synchronization signal block in the first synchronization signal block configuration and the synchronization signal block in the second synchronization signal block configuration are different;

[0087] The transmission number of the synchronization signal block in the first synchronization signal block configuration and the synchronization signal block in the second synchronization signal block configuration are different;

[0088] The transmission type of the synchronization signal block in the first synchronization signal block configuration and the synchronization signal block in the second synchronization signal block configuration are different.

[0089] Exemplarily, the transmission density being different includes at least one of the following: the period being different, the subcarrier spacing being different, the repetition number being different.

[0090] Exemplarily, the period of the synchronization signal block in the first synchronization signal block configuration and the synchronization signal block in the second synchronization signal block configuration being different means that the period of the synchronization signal block in the first synchronization signal block configuration and the period of the synchronization signal block in the second synchronization signal block configuration are not the same. The synchronization signal block period is the period of the synchronization signal block burst set. For example, the value of the configuration parameter ssb-periodicityServingCell is different. In an example, the period of the first synchronization signal block configuration is 20 ms, and the period of the second synchronization signal block configuration is 80 ms.

[0091] Exemplarily, the subcarrier spacing of the synchronization signal block in the first synchronization signal block configuration and the synchronization signal block in the second synchronization signal block configuration being different means that the subcarrier spacing of the synchronization signal block in the first synchronization signal block configuration and the subcarrier spacing of the synchronization signal block in the second synchronization signal block configuration are not the same. For example, the value of the configuration parameter subCarrierSpacingCommon is different. In an example, the subcarrier spacing of the first synchronization signal block configuration is 15 kHz, and the subcarrier spacing of the second synchronization signal block configuration is 30 kHz.

[0092] Exemplarily, the repetition number of the synchronization signal block in the first synchronization signal block configuration and the synchronization signal block in the second synchronization signal block configuration being different means that the repetition number of the synchronization signal block in the first synchronization signal block configuration and the repetition number of the synchronization signal block in the second synchronization signal block configuration are not the same. For example, the repetition number of the synchronization signal block in the first synchronization signal block configuration is 2 times. The repetition number of the synchronization signal block in the second synchronization signal block configuration is 4 times.

[0093] Exemplarily, the different transmission quantity includes at least one of the following: different number of SSBs transmitted in one SSB burst set, different number of SSB burst sets transmitted in one time period.

[0094] Exemplarily, the different transmission quantity of the synchronization signal blocks in the first synchronization signal block configuration and the second synchronization signal block configuration means that the number of synchronization signal blocks contained in a synchronization signal block burst set in the first synchronization signal block configuration is different from the number of synchronization signal blocks contained in a synchronization signal block burst set in the second synchronization signal block configuration. For example, the number of synchronization signal blocks contained in a synchronization signal block burst set in the first synchronization signal block configuration is 4, and the number of synchronization signal blocks contained in a synchronization signal block burst set in the second synchronization signal block configuration is 8.

[0095] Exemplarily, the different transmission type includes at least one of the following: different information carried by the synchronization signal blocks, different time domain resources of the synchronization signal blocks, different frequency domain resources of the synchronization signal blocks, and different code domain resources of the synchronization signal blocks.

[0096] Exemplarily, the different information carried by the synchronization signal blocks in the first synchronization signal block configuration and the second synchronization signal block configuration means that the content in a master information block (MIB) carried by the synchronization signal blocks in the first synchronization signal block configuration is different from the content in the MIB carried by the synchronization signal blocks in the second synchronization signal block configuration. The different content in the MIB includes: cell identification information, reference signal position information, physical downlink control channel (PDCCH) configuration information, cell barring information, and / or intra-frequency reselection information. For example, the cell identification information is a physical cell identity (PCID). The reference signal position information is dmrs-TypeA-position. The PDCCH configuration information is PDCCH-configSIB1. The cell barring information is cellBarred. The intra-frequency reselection information is intraFreqReselection.

[0097] Exemplarily, the time domain resources of the synchronization signal blocks in the first synchronization signal block configuration are different from the time domain resources of the synchronization signal blocks in the second synchronization signal block configuration, which means that the time slots occupied by the synchronization signal blocks in the first synchronization signal block configuration or the symbols occupied in one time slot are different from the time slots occupied by the synchronization signal blocks in the second synchronization signal block configuration or the symbols occupied in one time slot. For example, the synchronization signal blocks in the first synchronization signal block configuration occupy time slot 1 to time slot 2 in one subframe. The synchronization signal blocks in the second synchronization signal block configuration occupy time slot 3 to time slot 4 in one subframe.

[0098] Exemplarily, the frequency domain resources of the synchronization signal blocks in the first synchronization signal block configuration are different from the frequency domain resources of the synchronization signal blocks in the second synchronization signal block configuration, which means that the frequency domain resource units or frequency domain resource blocks occupied by the synchronization signal blocks in the first synchronization signal block configuration are different from the frequency domain resource units or frequency domain resource blocks occupied by the synchronization signal blocks in the second synchronization signal block configuration. For example, the synchronization signal blocks in the first synchronization signal block configuration occupy frequency domain resource block 0 to frequency domain resource block 19. The synchronization signal blocks in the second synchronization signal block configuration occupy frequency domain resource block 20 to frequency domain resource block 39. A frequency domain resource unit (RE) includes one or more subcarriers, and a frequency domain resource block (RB) includes one or more frequency domain resource units.

[0099] Exemplarily, the code domain resources of the synchronization signal blocks in the first synchronization signal block configuration are different from the code domain resources of the synchronization signal blocks in the second synchronization signal block configuration, which means that the spreading codes scrambled by the synchronization signal blocks in the first synchronization signal block configuration are different from the spreading codes scrambled by the synchronization signal blocks in the second synchronization signal block configuration. For example, the synchronization signal blocks in the first synchronization signal block configuration are scrambled by spreading code 1. The synchronization signal blocks in the second synchronization signal block configuration are scrambled by spreading code 2.

[0100] Exemplarily, the transmission types of the synchronization signal blocks in the first synchronization signal block configuration are different from the transmission types of the synchronization signal blocks in the second synchronization signal block configuration, which means that the uses of the first synchronization signal block configuration are different from the uses of the second synchronization signal block configuration. For example, the uses of the first synchronization signal block configuration are synchronization signal blocks used by nodes in an idle state. The uses of the second synchronization signal block configuration are synchronization signal blocks used by nodes in a connected state.

[0101] In some embodiments, the synchronization signal blocks of the fourth synchronization signal block configuration correspond to a first beam set, the first beam set includes one or more first beams, and one first beam corresponds to one first beam index; the synchronization signal blocks of the third synchronization signal block configuration correspond to a second beam set, the second beam set includes one or more second beams, and one second beam corresponds to one second beam index.

[0102] information in the second beam shared system information block in the second beam set.

[0103] In some embodiments, the association between the second beam set and the first beam set comprises:

[0104] One second beam index corresponds to one or more first beam indices.

[0105] The second beam set comprises one or more first beam groups, and the first beam group is a subset of the first beam set.

[0106] In some embodiments, the type of each synchronization signal block configuration in the one or more synchronization signal block configurations is determined according to at least one of: resource location of the synchronization signal block, information carried by the synchronization signal block.

[0107] In an example, the type of the synchronization signal block configuration is determined by the resource location.

[0108] In some embodiments, the resource location of the synchronization signal block comprises at least one of: location of time domain resource, location of frequency domain resource, location of code domain resource.

[0109] Different types of synchronization signal blocks correspond to at least one of: specific time domain resource location, frequency domain resource location, code domain resource location within a part of bandwidth.

[0110] In some embodiments, the resource location of the synchronization signal block comprises a first resource to which the synchronization signal block is mapped; and the first resource comprises at least one of the following types:

[0111] Physical Random Access Channel (PRACH);

[0112] Physical Uplink Control Channel (PUCCH);

[0113] Physical Uplink Shared Channel (PUSCH).

[0114] As a possible implementation, in the case where the type of the first resource is PRACH, the first resource comprises:

[0115] one or more PRACH occasions;

[0116] one or more pilot sequences in one PRACH occasion.

[0117] In some embodiments, the first resource is related to the synchronization signal block, comprising:

[0118] The first resource is offset from the synchronization signal block in the time domain.

[0119] The first resource is offset from the synchronization signal block in the frequency domain.

[0120] In some embodiments, the information carried by the synchronization signal block includes a type index in the synchronization signal block, one type index corresponding to one type of the synchronization signal block configuration.

[0121] In an example, the type of the synchronization signal block configuration is determined by the information carried by the synchronization signal block. For example, the type information is carried in the synchronization signal block. The type information is determined by a type index of the synchronization signal block. For example, one type of the synchronization signal block corresponds to one type index. The correspondence between the type index and the synchronization signal block is determined by a higher layer parameter.

[0122] In some embodiments, different types of synchronization signal blocks are mapped in different first resources. Exemplarily, the following implementation manners can be provided:

[0123] Implementation manner one, the third synchronization signal block and the fourth synchronization signal block are mapped in different first resources; the third synchronization signal block is mapped to the first resource according to a first proportion, and the fourth synchronization signal block is mapped to the first resource according to a second proportion, the first proportion and the second proportion have different values.

[0124] As a possible implementation manner, the mapping of the third synchronization signal block and the fourth synchronization signal block is independent of each other; the mapping of the third synchronization signal block corresponds to a first associated period, and the mapping of the fourth synchronization signal block corresponds to a second associated period; the first associated period and the second associated period are independent of each other; the first associated period and the second associated period are associated periods for the mapping of the synchronization signal block and the PRACH occasion.

[0125] As another possible implementation manner, the mapping of the third synchronization signal block and the fourth synchronization signal block is associated; the mapping of the third synchronization signal block corresponds to a first associated period, and the mapping of the fourth synchronization signal block corresponds to a second associated period; the first associated period and the second associated period constitute a third associated period; the third associated period is an associated period for the mapping of the synchronization signal block and the PRACH occasion.

[0126] In some embodiments, one or more first associated periods and / or second associated periods constitute an associated mode period.

[0127] In some embodiments, the third synchronization signal block is mapped based on a first criterion; the first criterion is that the channel quality of one or more synchronization signal blocks in the second beam set is greater than a preset channel quality threshold; in the case of meeting the first criterion, the third synchronization signal block is mapped.

[0128] In a second implementation, the synchronization signal blocks of the first beam set are mapped in different first resources; and some or all of the synchronization signal blocks in the third synchronization signal block configuration are mapped in predefined first resources.

[0129] In some embodiments, the step S202 comprises at least one of the following implementations:

[0130] detecting the synchronization signal blocks based on the first synchronization signal block configuration or the third synchronization signal block configuration, activating the second synchronization signal block configuration based on the first condition and detecting the synchronization signal blocks of the second synchronization signal block configuration or the fourth synchronization signal block configuration;

[0131] detecting the synchronization signal blocks based on the first synchronization signal block configuration or the third synchronization signal block configuration, and detecting the synchronization signal blocks of the second synchronization signal block configuration or the fourth synchronization signal block configuration based on the information carried in the first synchronization signal block configuration or the third synchronization signal block configuration;

[0132] detecting the synchronization signal blocks based on one of the first synchronization signal block configuration or the second synchronization signal block configuration, and detecting the synchronization signal blocks based on the other of the first synchronization signal block configuration or the second synchronization signal block configuration based on the first condition.

[0133] In some embodiments, the first synchronization signal block configuration and the second synchronization signal block configuration satisfy any of the following conditions:

[0134] The first synchronization signal block configuration is a synchronization signal block configuration for channel quality measurement, and the second synchronization signal block configuration is a synchronization signal block configuration for area access;

[0135] The first synchronization signal block configuration is a synchronization signal block configuration used by nodes in an idle state, and the second synchronization signal block configuration is a synchronization signal block configuration used by nodes in a connected state;

[0136] The first synchronization signal block configuration is a synchronization signal block configuration applicable to a first bandwidth, and the second synchronization signal block configuration is a synchronization signal block configuration applicable to a second bandwidth.

[0137] For example, the step S202 can be implemented as follows: the first node first detects the synchronization signal blocks based on a synchronization signal block configuration applicable to channel quality measurement, and then activates a synchronization signal block configuration applicable to area access based on the first condition and detects the synchronization signal blocks of the synchronization signal block configuration applicable to area access.

[0138] Exemplarily, the step S202 can be implemented as follows: the first node first detects the synchronization signal blocks based on the synchronization signal block configuration used by the nodes in the idle state, and then activates the synchronization signal block configuration used by the nodes in the connected state based on the first condition, and detects the synchronization signal blocks of the synchronization signal block configuration used by the nodes in the connected state.

[0139] Exemplarily, the step S202 can be implemented as follows: the first node first detects the synchronization signal blocks based on the synchronization signal block configuration suitable for the first bandwidth, and then activates the synchronization signal block configuration suitable for the second bandwidth based on the first condition, and detects the synchronization signal blocks of the synchronization signal block configuration suitable for the second bandwidth.

[0140] The first condition will be described below, and will not be described here.

[0141] In some embodiments, in the synchronization signal block configuration for channel quality measurement, the multiple synchronization signal block burst sets are periodically transmitted.

[0142] In some embodiments, in the synchronization signal block configuration for channel quality measurement, one synchronization signal block burst set includes one or more synchronization signal blocks, and each synchronization signal block is associated with a first area.

[0181] For ease of understanding, the information transmission method provided by the embodiments of the present disclosure is described below in combination with an example use scenario.

[0182] In use scenario one, a super cell and a micro cell share a set of synchronization signal block configurations.

[0183] Exemplarily, the implementation manner of the synchronization signal block detection based on the one synchronization signal block configuration in this scenario is to detect the synchronization signal block based on one configuration of the first synchronization signal block configuration, activate another configuration of the first synchronization signal block configuration based on a first condition, and detect the synchronization signal block.

[0184] Exemplarily, the first region includes a coverage area of a super cell. Exemplarily, the second region includes a coverage area of a micro cell. For example, the first region identifier includes a PCID. The second region identifier includes a virtual cell identifier (VCID).

[0185] Exemplarily, under the configuration of the super cell and the micro cell, a first synchronization signal block configuration is configured to realize the change of the synchronization signal block content transmission of each micro cell.

[0186] Exemplarily, based on FIG. 2, the cell types provided by the base station include a super cell and a micro cell. Exemplarily, in use scenario one, the super cell and the micro cell are associated through a PCID and a VCID. One PCID corresponds to one super cell, and one PCID includes one or more VCIDs, and each VCID corresponds to one micro cell. For example, as shown in FIG. 2, one PCID is associated with six VCIDs.

[0187] Exemplarily, the above-mentioned VCID information can be a sub-physical cell number or implicitly indicated in the form of a bit map (BitMap).

[0188] Exemplarily, the synchronization signal block configuration for the super cell is configured as the first synchronization signal block configuration, including the synchronization signal block for channel quality measurement. Exemplarily, the synchronization signal block configuration for the super cell is configured as the second synchronization signal block configuration, including the synchronization signal block for regional access. In some embodiments, the synchronization signal block in the synchronization signal block configuration for the super cell includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Exemplarily, the synchronization signal block in the configuration includes the PSS. Exemplarily, the synchronization signal block in the configuration includes the SSS. In some embodiments, in the synchronization signal block configuration for the super cell, a plurality of synchronization signal blocks are contained in one synchronization signal block burst. Each synchronization signal block corresponds to one micro cell. In some embodiments, the PCID information is contained in the synchronization signal block.

[0189] Exemplarily, the synchronization signal block configuration for the micro cell is configured as the first synchronization signal block configuration or the second synchronization signal block configuration for the super cell. Exemplarily, the synchronization signal block in the synchronization signal block configuration for the micro cell is different from the content carried by the synchronization signal block in the synchronization signal block configuration for the micro cell. In some embodiments, the synchronization signal block in the synchronization signal block configuration for the micro cell includes the PSS, the SSS and a master information block (MIB). In some embodiments, the synchronization signal block in the synchronization signal block configuration for the micro cell includes the MIB. For example, the MIB includes the VCID.

[0190] As shown in FIG. 5, based on the first use case, the information transmission method provided by the embodiments of the present disclosure includes:

[0191] In an example, the base station sends a set of synchronization signal block configurations (the first synchronization signal block configuration or the second synchronization signal block configuration) to the UE based on the super cell, including the synchronization signal block configuration for channel quality measurement or the synchronization signal block configuration for regional access; accordingly, the UE first receives the synchronization signal block configuration, for synchronization within the super cell, channel quality measurement and / or initial access.

[0192] For example, the synchronization signal block configuration (first synchronization signal block configuration or second synchronization signal block configuration) includes a simplified synchronization signal block configuration and a normal synchronization signal block configuration. The simplified synchronization signal block configuration can be a synchronization signal block configuration configured for a super cell. The normal synchronization signal block configuration can be a synchronization signal block configuration configured for a micro cell.

[0193] In an example, the simplified synchronization signal block configuration is a simplified SSB configuration. The normal synchronization signal block configuration is a normal SSB configuration. The simplified SSB includes a PSS and a SSS. In some embodiments, the simplified SSB can also carry a period or a set of periods of the normal SSB.

[0194] In an example, the UE performs synchronization signal block detection based on a set of received synchronization signal block configurations, and activates and detects a normal synchronization signal block configuration of a first cell based on a first condition and a best first cell detected based on a reference signal.

[0195] Exemplarily, the first condition includes that the first node transmits first information. Exemplarily, the first information includes a resource location of the synchronization signal block configuration. In some embodiments, the resource location of the synchronization signal block configuration includes a time domain location of a normal SSB in an SSB burst set. For example, the time domain location of the normal SSB in the SSB burst set is represented by a bitmap. As shown in FIG. 5, six SSBs are transmitted in one SSB burst set, and the bitmap has a length of 6 bits. When the fourth SSB is a normal SSB, the indication is '000100'. Exemplarily, the first information includes trigger information of the synchronization signal block configuration. In some embodiments, the trigger information of the synchronization signal block configuration includes 1 bit. For example, when the information is indicated as 1, it means that a certain simplified SSB needs to be converted / switched to a normal SSB. In some embodiments, the first resource is a PRACH channel. The base station determines the SSB that needs to be converted / switched through the mapping relationship between the SSB and the PRACH channel.

[0196] Exemplarily, the first condition comprises that the first node receives second signaling. Exemplarily, the second signaling comprises periodicity information of a synchronization signal block. In some embodiments, the periodicity information of the synchronization signal block comprises periodicity information of a normal SSB.

In some embodiments, the synchronization signal block configuration activation indication information comprises activation indication information of a normal SSB. For example, the time domain position of a normal SSB in a synchronization signal block burst set is represented by a bitmap. As shown in FIG. 5, six SSBs are transmitted in one synchronization signal block burst set, and the length of the bitmap is 6 bits. When the fourth SSB is a normal SSB, the indication is '000100'.

[0197] Exemplarily, the second signaling comprises DCI format 1_0, and / or DCI format 2_7.

[0198] Exemplarily, the second signaling comprises MAC CE signaling.

[0200] The first cell is a micro cell.

[0201] In an example, the normal synchronization signal block is a normal SSB.

[0202] Exemplarily, the first condition triggers the first cell to convert a simplified SSB corresponding to the first cell into a normal SSB.

[0203] In an example, the first condition activates a normal synchronization signal block corresponding to the first cell.

[0204] In an example, the normal synchronization signal block is a normal SSB. In an example, the activation of the normal synchronization signal block is to replace a simplified synchronization signal block with the normal synchronization signal block for transmission.

[0205] In some embodiments, the base station can also dynamically configure and transmit multiple normal SSBs on demand.

[0206] In some embodiments, the base station can also dynamically adjust the period of the normal SSB.

[0207] Exemplarily, the period of the normal SSB can be different from that of the simplified SSB.

[0208] Exemplarily, as shown in FIG. 6, the base station converts the simplified SSB corresponding to the first cell into a normal SSB based on the first condition, and further, the base station can dynamically configure and transmit multiple normal SSBs according to network requirements. It can be seen that the period of the normal SSB is different from that of the simplified SSB.

[0209] In some embodiments, the UE can assume that a few normal SSBs are repeated to increase the number of normal SSBs received by the UE within the normal SSB window to quickly access the cell.

[0210] The second scenario uses super cells and micro cells to respectively transmit different synchronization signal block configurations.

[0211] Exemplarily, the detection of the synchronization signal block based on the multiple different synchronization signal block configurations is implemented by detecting the synchronization signal block based on the first synchronization signal block configuration, activating the second synchronization signal block configuration based on the first condition, and detecting the synchronization signal block of the second synchronization signal block configuration. Alternatively, the detection of the synchronization signal block based on the multiple different synchronization signal block configurations is implemented by detecting the synchronization signal block based on the first synchronization signal block configuration, and detecting the synchronization signal block of the second synchronization signal block configuration or the fourth synchronization signal block configuration based on the information carried in the first synchronization signal block configuration.

[0266] In some embodiments, the SSB in the SSB configuration used by nodes in an idle state is a cell defining SSB (CD-SSB), and the SSB in the SSB configuration used by nodes in a connected state is a non-cell defining SSB (NCD-SSB). The switching between the SSB used by nodes in an idle state and the SSB used by nodes in a connected state is triggered by DCI signaling or MAC control element (MAC CE) signaling.

[0267] For example, when the cell intends to be a primary cell, the second node transmits the SSB used by nodes in an idle state, which can be detected by both nodes in an idle state and nodes in a connected state, for initial access or time-frequency synchronization. At this time, the second node informs the nodes in a connected state of the change of the SSB configuration through the second signaling (e.g., DCI signaling or MAC CE signaling). When the cell intends to be a capacity secondary cell, the second node transmits the SSB used by nodes in a connected state. At this time, only the nodes in a connected state can detect and use the SSB used by nodes in a connected state for time-frequency synchronization.

[0268] For example, the information for indicating the SSB configuration change includes one 1-bit enabling bit. When the bit takes the first value, the current base station transmits the SSB used by the node in the idle state, and when the bit takes the second value, the current base station transmits the SSB used by the node in the connected state. Alternatively, the information for indicating the SSB configuration change includes an N-bit information field. N is an integer greater than 0. In some embodiments, N is related to the number of configurable SSB configurations. For example, N = log2(K), K is an integer greater than 0, and K is the number of SSB configurations. The N-bit information field indicates the index of the SSB configuration. The SSB configuration indicated by the index is activated, and the current SSB configuration is deactivated.

[0269] For example, the DCI is used to carry the information for indicating the SSB configuration change. In some embodiments, the DCI is a DCI format 1_0 with Cyclic Redundancy Check (CRC) scrambling System Information Radio Network Temporary Identifier (SI-RNTI). In some embodiments, the DCI is a DCI format 2_7.

[0270] In some embodiments, the SSB used by the node in the connected state includes at least one of the following: CD-SSB, NCD-SSB, SSB not in syn raster.

[0271] In some embodiments, the multiple synchronization signal block configurations determined by the second node include the SSB configuration used by the node in the connected state.

[0272] As a possible implementation, the multiple synchronization signal block configurations include SSB configurations with different PCIDs. Illustratively, these SSB configurations with different PCIDs exist within one BWP activated by the terminal.

[0273] As another possible implementation, the multiple synchronization signal block configurations include SSB configurations with the same PCID.

[0274] In some embodiments, the multiple synchronization signal block configurations described above can be repeated multiple times within a period of one SSB burst set configuration, and the number of repetitions is determined by a higher layer parameter. For example, the repetition of the burst set starts from the next slot of the slot occupied by the last SSB of the last transmission of the burst set. When the specified number of repetitions is reached, the repeated transmission stops. For example, the SSB burst set is repeated once, and the first transmission is performed on slot 0 and slot 1. In the repeated transmission, the repeated SSB burst set continues to be transmitted on slot 2. For example, the repeated SSB burst set is transmitted on slot 2 and slot 3.

[0275] In some embodiments, the method of detecting the synchronization signal block based on the multiple different synchronization signal block configurations comprises: detecting the synchronization signal block based on one configuration of the first synchronization signal block, and activating another configuration of the first synchronization signal block based on the first condition and detecting the synchronization signal block. Alternatively, detecting the synchronization signal block based on one configuration of the second synchronization signal block, and activating another configuration of the second synchronization signal block based on the first condition and detecting the synchronization signal block.

[0276] For example, the first synchronization signal block configuration comprises a synchronization signal block configuration used by the node in the idle state. For example, the synchronization signal block configuration used by the node in the idle state comprises an SSB configuration used by the node in the idle state. For example, the second synchronization signal block configuration comprises a synchronization signal block configuration used by the node in the connected state. For example, the synchronization signal block configuration used by the node in the connected state comprises an SSB configuration used by the node in the connected state.

[0277] For example, the node in the idle state comprises a node in the idle mode and a node in the inactive mode. The node in the connected state comprises a node in the connected mode.

[0278] For example, the SSB configuration determined (or transmitted) by the second node (the SSB configuration configured by the second node to the first node) comprises: an SSB configuration used by the node in the idle state or an SSB configuration used by the node in the connected state. The method further comprises: the first node adapts to the SSB configuration, and detects the corresponding SSB configuration based on the first condition. For example, the first condition comprises that the first node receives the second signaling, which has the following cases:

[0279] (1) Based on the baseline period and the additional period configured by the higher layer parameter.

[0280] The higher layer parameter comprises at least one of the following: SIB1, RRC signaling.

[0281] In some embodiments, the baseline period and the additional period are switched based on the received second signaling.

[0282] In some embodiments, the baseline period and the additional period are configured by a higher layer parameter, and the additional period in the higher layer parameter is activated or deactivated by the second signaling.

[0283] For example, the activation indication information can include 1 bit. If the bit is “1”, it indicates that the additional period is activated, and the period of the synchronization signal block is the additional period. If the bit is “0”, it indicates that the additional period is deactivated, and the period of the synchronization signal block is the baseline period. Alternatively, if the bit is “0”, it indicates that the additional period is activated, and the period of the synchronization signal block is the additional period. If the bit is “1”, it indicates that the additional period is deactivated, and the period of the synchronization signal block is the baseline period.

[0284] For example, the higher layer parameter configures a baseline period of 80 ms and an additional period of 20 ms, which are period 1 and period 2 respectively. The second signaling activates or deactivates period 2. When the second signaling indicates “1”, it indicates that period 2 is activated, and the period of the synchronization signal block is 20 ms. When the second signaling indicates “0”, it indicates that period 2 is deactivated, and the period of the synchronization signal block is 80 ms.

[0285] (2) Number the periods configured by the higher layer parameter, and each period corresponds to a number.

[0286] In some embodiments, the second signaling indicates the number of the period to be switched.

[0287] For example, the activation indication information includes multiple bits. The bit length of the activation indication information is related to the number of the maximum period that can be represented. Each period is associated with an identification (ID) or each period is associated with a number. In some embodiments, the second signaling indicates the ID of the activated synchronization signal block configuration period. In some embodiments, the second signaling indicates the number of the activated synchronization signal block configuration period.

[0288] For example, the periods that can be represented are 5 ms, 10 ms, 20 ms, and 40 ms. Therefore, the bit length of the activation indication information is log2(4) = 2. For the periods that can be represented, the numbers of the periods are: the 5 ms period is numbered “00”, the 10 ms period is numbered “01”, the 20 ms period is numbered “10”, and the 40 ms period is numbered “11”. The relationship between the period and the period number is determined by the higher layer parameter. When the second signaling indicates that the activation indication information indicates “10”, it indicates that the period configured by the synchronization signal block is 20 ms.

[0289] (3) Transmission indication based on SSB burst set transmitted within a preset time period.

[0290] In some embodiments, the second signaling carries synchronization signal block transmission indication information. For example, the synchronization signal block transmission indication information can be bitmap information. Each bit in the bitmap information corresponds to an SSB burst set. For example, when the bit takes a first value, it indicates that the synchronization signal block burst set is transmitted, and when the bit takes a second value, it indicates that the synchronization signal block burst set is not transmitted. For example, bit "1" indicates that the SSB burst set is transmitted, and bit "0" indicates that the SSB burst set is not transmitted; or, bit "0" indicates that the SSB burst set is transmitted, and bit "1" indicates that the SSB burst set is not transmitted.

[0291] For example, assuming that a total of 4 SSB burst sets are transmitted within a preset time period, the bitmap information of the transmission indication uses 4 bits to indicate, and the bitmap information of the transmission indication is "1101", indicating that the first, second, and fourth SSB burst sets are transmitted, and the third SSB burst set is not transmitted.

[0292] For example, within a preset time period, the bitmap information of the current transmission indication of the SSB burst set is "1101". When adaptive changes need to be made to the transmission of the SSB in the SSB burst set, the bitmap information of the transmission indication carried by the second signaling is "1011". After receiving the second signaling, the UE receives the first, third, and fourth SSB burst sets, and does not receive the second SSB burst set.

[0293] (4) Define a synchronization signal block configuration effective time period.

[0294] In some embodiments, the second signaling carries a synchronization signal block configuration effective time period. For example, the effective time period is determined by a starting time point and the length of the effective time. For example, the effective time period is determined by a starting time point and an ending time point.

[0295] For example, the starting time point is determined by a reference time point. The reference time point can be determined by the length of the effective time and a predefined offset. For example, the starting time point P can be a system frame whose system frame number (SFN) satisfies SFN mod x=k. SFN represents the system frame number, x represents the length of the effective time, x is an integer greater than or equal to 1, and k represents a predefined offset, k is an integer greater than or equal to 0. The length of the effective time is determined by a high-level parameter.

[0296] In some embodiments, the reference time point is a last symbol of the second signaling received by the first node. In some embodiments, the reference time point is a slot of the second signaling received by the first node. In some embodiments, the reference time point is a slot of the second signaling received by the first node. In some embodiments, the reference time point is a subframe of the second signaling received by the first node. In some embodiments, the reference time point is a Radio frame of the second signaling received by the first node.

[0297] In some embodiments, the transmission of the synchronization signal block is performed when the first node is in the validity time period, and the transmission of the synchronization signal block is not performed when the first node is not in the validity time period.

[0298] In some embodiments, the synchronization signal block is transmitted according to one configuration of the synchronization signal block when the first node is in the validity time period, and the synchronization signal block is transmitted according to another configuration of the synchronization signal block when the first node is not in the validity time period.

[0299] In some embodiments, the validity time period comprises a Discontinuous Transmission (DTX) active time.

[0300] In some embodiments, the validity time period comprises a DTX inactive time.

[0301] (5) The activation indication information of the synchronization signal block configuration.

[0302] In some embodiments, a plurality of synchronization signal block configurations are configured by a high layer parameter, and one of the plurality of synchronization signal block configurations is activated or deactivated by the second signaling.

[0303] Exemplarily, the activation indication information can comprise 1 bit, for example, if the bit is valued as "1", it indicates that the synchronization signal block configuration is activated, and if the bit is valued as "0", it indicates that the synchronization signal block configuration is deactivated; or, if the bit is valued as "0", it indicates that the synchronization signal block configuration is activated, and if the bit is valued as "1", it indicates that the synchronization signal block configuration is deactivated.

[0304] Exemplarily, the higher layer parameter configures two synchronization signal block configurations, configuration 1 and configuration 2. The second signaling activates or deactivates configuration 2. When the second signaling indicates “1”, it means that configuration 2 is activated. When configuration 2 is activated, configuration 1 is deactivated. When the second signaling indicates “0”, it means that configuration 2 is deactivated. When configuration 2 is deactivated, configuration 1 is activated. In some embodiments, in configuration 1 and configuration 2, the periods of synchronization signal blocks are different. In some embodiments, in configuration 1 and configuration 2, the numbers of synchronization signal blocks in a synchronization signal block burst set are different. In some embodiments, in configuration 1 and configuration 2, the subcarrier spacings of synchronization signal blocks are different.

[0305] Exemplarily, the activation indication information includes multiple bits. The bit length of the activation indication information is related to the maximum number of synchronization signal configurations that can be represented. Each synchronization signal configuration is associated with an identification (ID). The second signaling indicates the ID of the activated synchronization signal configuration.

[0306] Exemplarily, the multiple synchronization signal block configurations configured by the higher layer parameter include an on demand synchronization signal block configuration. Exemplarily, the on demand synchronization signal block configuration includes an on demand SSB configuration. Exemplarily, the on demand synchronization signal block configuration includes an on demand triggered SSB configuration. Exemplarily, the on demand synchronization signal block configuration includes an aperiodic SSB configuration. Exemplarily, the on demand synchronization signal block configuration includes a discontinuous transmitted SSB. Exemplarily, the on demand synchronization signal block configuration is transmitted in a predefined time period. In some embodiments, the predefined time period can be determined by the number of times of synchronization signal block burst set transmission. In some embodiments, the predefined time period can be determined by a predefined time length.

[0307] In the following, the related content of the second signaling referred to above is described.

[0308] In some embodiments, the second signaling includes at least one of the following: DCI signaling, MAC CE signaling, and higher layer parameter. Exemplarily, the higher layer parameter includes RRC signaling.

[0309] Exemplarily, the second signaling includes RRC signaling and MAC CE signaling. Exemplarily, the RRC signaling activates one synchronization signal block configuration in the multiple synchronization signal block configurations. Exemplarily, the MAC CE signaling activates one synchronization signal block configuration. Exemplarily, the MAC CE signaling deactivates one synchronization signal block configuration.

[0310] Exemplarily, the second signaling comprises RRC signaling and DCI signaling. Exemplarily, the RRC signaling activates one of the plurality of synchronization signal block configurations. Exemplarily, the DCI signaling activates one synchronization signal block configuration. Exemplarily, the DCI signaling deactivates one synchronization signal block configuration.

[0311] Exemplarily, the RRC signaling configures one or more synchronization signal block configurations. Exemplarily, the one or more synchronization signal block configurations comprise a default synchronization signal block configuration. Exemplarily, the RRC signaling activates the default synchronization signal block configuration.

[0312] In some embodiments, the validity time of the second signaling is determined by a starting time point of the validity time and a length of the validity time.

[0313] The starting time point of the validity time is determined based on a reference time point.

[0314] Exemplarily, the reference time point can be determined according to the length of the validity time and a predefined offset. For example, the starting time point P can be a system frame whose system frame number satisfies SFN mod x=k. SFN represents the system frame number, x represents the length of the validity time, x is an integer greater than or equal to 1, and k represents the predefined offset, k is an integer greater than or equal to 0. The length of the validity time is determined by a higher layer parameter.

[0315] Exemplarily, the reference time point can be determined according to a time point of receiving the second signaling. For example, the reference time point is the Pth symbol after the last symbol of receiving the second signaling. For example, the reference time point is the Pth slot after the slot of receiving the second signaling. P is an integer greater than 0.

[0316] In some embodiments, the second signaling comprises first indication content and second indication content. The first indication content is used to indicate the synchronization signal block configuration in the current validity time period. The second indication content is used to indicate the synchronization signal block configuration in the next validity time period.

[0317] In some embodiments, the second signaling is repeatedly transmitted multiple times within the validity time period.

[0318] In some embodiments, the second signaling is repeatedly transmitted multiple times before the validity time period.

[0319] In some embodiments, the first condition comprises performing the operation of activating the synchronization signal block configuration upon expiry of the timer. For example, the operation of activating the synchronization signal block configuration upon expiry of the timer comprises activating one of the synchronization signal block configurations upon expiry of the timer, and activating another of the synchronization signal block configurations upon expiry of the timer. For example, a high layer parameter configures two synchronization signal block configurations, including configuration 1 and configuration 2. Within a time range in which the timer is valid, configuration 1 is used, and the first node performs synchronization signal block detection based on configuration 1. Within a time range in which the timer is invalid, configuration 2 is used, and the first node performs synchronization signal block detection based on configuration 2. In some embodiments, the synchronization signal blocks in configuration 1 and configuration 2 have different periodicities. In some embodiments, the synchronization signal blocks in configuration 1 and configuration 2 have different numbers of synchronization signal blocks in a synchronization signal block burst set. In some embodiments, the synchronization signal blocks in configuration 1 and configuration 2 have different subcarrier spacings.

[0320] For example, the operation of activating the synchronization signal block configuration upon expiry of the timer comprises activating one of the synchronization signal block configurations upon expiry of the timer, and activating another of the synchronization signal block configurations upon expiry of the timer. For example, a high layer parameter configures two synchronization signal block configurations, including two periodicities, including periodicity 1 and periodicity 2. Within a time range in which the timer is valid, periodicity 1 is used, and the first node performs synchronization signal block detection based on periodicity 1 of the synchronization signal block configuration. Within a time range in which the timer is invalid, periodicity 2 is used, and the first node performs synchronization signal block detection based on periodicity 2 of the synchronization signal block configuration.

[0321] Example 2: Application of a synchronization signal block applicable to a first bandwidth, and a synchronization signal block applicable to a second bandwidth.

[0322] For example, the detection of the synchronization signal block based on the multiple different synchronization signal block configurations is implemented by detecting the synchronization signal block based on the first synchronization signal block configuration, activating the second synchronization signal block configuration based on the first condition, and detecting the synchronization signal block of the second synchronization signal block configuration. Alternatively, the detection of the synchronization signal block based on the multiple different synchronization signal block configurations is implemented by detecting the synchronization signal block based on the first synchronization signal block configuration, and detecting the synchronization signal block of the second synchronization signal block configuration based on information carried in the first synchronization signal block configuration.

[0323] The second bandwidth is greater than the first bandwidth.

[0324] For example, the following is described by taking the second bandwidth as a wide bandwidth and the first bandwidth as a narrow bandwidth.

[0325] In some embodiments, the one or more synchronization signal block configurations determined by the second node comprise a first synchronization signal block configuration and a second synchronization signal block configuration; the first synchronization signal block comprises a SSB suitable for a narrow bandwidth; and the second synchronization signal block comprises a SSB suitable for a wide bandwidth.

[0326] In some embodiments, the first node detects a SSB suitable for a narrow bandwidth, and selects a desired BWP, and then further measures a channel quality of the selected BWP by a SSB suitable for a wide bandwidth.

[0327] In some embodiments, the first node detects a SSB suitable for a narrow bandwidth, and selects a desired carrier, and then accesses the selected carrier by a SSB suitable for a wide bandwidth.

[0328] In some embodiments, the first node detects a SSB suitable for a narrow bandwidth, and selects a desired carrier, and then accesses the selected carrier by a SSB suitable for a wide bandwidth.

[0329] In some embodiments, the first node detects a SSB suitable for a narrow bandwidth, and selects a desired carrier, and then accesses the selected carrier by a SSB suitable for a wide bandwidth.

[0330] In some embodiments, the one or more synchronization signal block configurations configured by the second node comprise a SSB suitable for a wide beam and a SSB suitable for a narrow beam.

[0331] In some embodiments, the one or more synchronization signal block configurations configured by the second node comprise a SSB suitable for a wide beam and a SSB suitable for a narrow beam.

[0332] In some embodiments, the wide beam can be a beam in the first beam set, and the narrow beam can be a beam in the second beam set; or the narrow beam can be a beam in the first beam set, and the wide beam can be a beam in the second beam set.

[0333] In some embodiments, the wide beam can be a beam in the first beam set, and the narrow beam can be a beam in the second beam set; or the narrow beam can be a beam in the first beam set, and the wide beam can be a beam in the second beam set.

[0334] In some embodiments, the SSB applicable to the narrow beam can be a synchronization signal block configured for a fourth synchronization signal block corresponding to the first beam set; the SSB applicable to the wide beam can be a synchronization signal block configured for a third synchronization signal block corresponding to the second beam set.

[0335] The burst set of the SSB applicable to the wide beam includes one or more SSBs, each SSB being numbered by an index, and each SSB representing one wide beam signal in the cell.

[0336] The burst set of the SSB applicable to the narrow beam includes one or more SSBs, each SSB being numbered by an index, and each SSB representing one narrow beam signal in the cell.

[0337] In some embodiments, the association between the second beam set and the first beam set is that one second beam index corresponds to one or more first beam indexes. For example, one SSB index applicable to the wide beam corresponds to one or more SSB indexes applicable to the narrow beam. The one or more SSB indexes applicable to the narrow beam corresponding to the one SSB index applicable to the wide beam are a subset of the indexes included in the SSB configuration applicable to the narrow beam.

[0338] For example, the first node detects a specific SSB index applicable to the wide beam, and can learn the associated SSB index applicable to the narrow beam according to the correspondence.

[0339] In some embodiments, the correspondence between the SSB index applicable to the wide beam and the SSB index applicable to the narrow beam is configured by the second node.

[0340] In an example, the correspondence between the SSB index applicable to the wide beam and the SSB index applicable to the narrow beam is in the SSB configuration applicable to the wide beam.

[0341] In an example, the SSBs in the burst set of the SSB applicable to the narrow beam share one SIB1 signal. The SIB1 signal includes the index information of the SSB applicable to the wide beam and the PRACH resource information.

[0342] For example, as shown in FIG. 9, one SSB burst set in the SSB configuration applicable to the wide beam includes 4 SSB signals. In the SSB configuration applicable to the narrow beam, one SSB burst set includes 16 SSB signals.

[0343] Based on the SSB configuration shown in FIG. 9, the first node selects SSB1.1 applicable to the wide beam as the downlink transmission beam after detection, and correspondingly, the first node can select one of SSB2.1, SSB2.2, SSB2.3, and SSB2.4 applicable to the narrow beam as the downlink transmission beam.

[0344] In some embodiments, the first node can trigger transmission of the SSB configuration applicable to the narrow beam.

[0345] Exemplarily, the first node activates the fourth synchronization signal block configuration based on a first condition. Exemplarily, the first condition comprises that the first node transmits first information. The first information comprises an index of a specified synchronization signal block configuration. Exemplarily, the index of the synchronization signal block configuration comprises an SSB index applicable to the narrow beam. Exemplarily, the SSB index applicable to the wide beam has a correspondence relationship with the first resource. The correspondence relationship is determined by a higher layer parameter. Exemplarily, the first information is transmitted on the first resource. In some embodiments, the first resource is one or more PRACH transmission occasions, or one or more pilot sequences in a PRACH transmission occasion. For example, by reporting the index of the SSB applicable to the wide beam through the first information, the second node triggers the transmission of the corresponding SSB applicable to the narrow beam according to the configured correspondence relationship (i.e., the correspondence relationship between the SSB index applicable to the wide beam and the SSB index applicable to the narrow beam).

[0346] Exemplarily, as shown in FIG. 10, the first node transmits on a specific PRACH occasion, and the second node can determine the wide beam SSB used by the first node according to the transmitted PRACH occasion and the mapping relationship of the SSB applicable to the wide beam. The first node correspondingly receives the SSB of the narrow beam under the wide beam SSB.

[0347] Exemplarily, the first node activates the fourth synchronization signal block configuration based on a first condition. Exemplarily, the first condition comprises that the first node receives second signaling. The second signaling comprises synchronization signal block transmission indication information. Exemplarily, the synchronization signal block transmission indication information is wide beam transmission indication information. Exemplarily, the wide beam transmission indication information can be bitmap information. For example, one bit in the bitmap information corresponds to one synchronization signal block. When the bit is of a first value, it indicates that the synchronization signal block (SSB) needs to be activated (enabled), and the corresponding narrow beam synchronization signal block (SSB) is activated (enabled) accordingly. When the bit is of a second value, it indicates that the synchronization signal block (SSB) needs to be deactivated (disabled), and the corresponding narrow beam synchronization signal block (SSB) is deactivated (disabled) accordingly.

[0348] Exemplarily, the second signaling comprises DCI format 1_0 and / or DCI format 2_7.

[0349] Exemplarily, the second signaling comprises MAC CE signaling.

[0350] Exemplarily, the second signaling comprises RRC signaling.

[0351] Example four, detecting synchronization signal blocks based on multiple synchronization signal block configurations, including detecting synchronization signal blocks based on the third synchronization signal block configuration, activating the fourth synchronization signal block configuration based on a first condition and detecting synchronization signal blocks of the fourth synchronization signal block configuration.

[0352] Exemplarily, the fourth synchronization signal block configuration includes SSBs applicable to single beams. Exemplarily, the third synchronization signal block configuration includes application of SSBs applicable to joint beams.

[0353] In some embodiments, the one or more synchronization signal block configurations determined by the second node include: SSBs applicable to single beams and SSBs applicable to joint beams.

[0354] Exemplarily, the single beams can be beams in the above-mentioned first beam set, and the joint beams can be beams in the above-mentioned second beam set; or, the joint beams can be beams in the above-mentioned first beam set, and the single beams can be beams in the above-mentioned second beam set. The SSBs applicable to single beams can be synchronization signal blocks of the fourth synchronization signal block configuration corresponding to the first beam set; the SSBs applicable to joint beams can be synchronization signal blocks of the third synchronization signal block configuration corresponding to the second beam set; or, the SSBs applicable to joint beams can be synchronization signal blocks of the fourth synchronization signal block configuration corresponding to the first beam set; the SSBs applicable to single beams can be synchronization signal blocks of the third synchronization signal block configuration corresponding to the second beam set.

[0355] Exemplarily, the first beam set includes one or more first beams. Exemplarily, the second beam is a first beam set. Exemplarily, the joint beam corresponds to a combination of multiple single beams. For example, the first beam set includes 4 beams, corresponding to 4 SSBs applicable to single beams. The second beam is a first beam set, including 2 first beams, i.e., the SSB of the joint beam includes 2 SSBs applicable to single beams.

[0356] In some embodiments, the mapping relationship between the SSB and the PRACH resource can include at least one of the following:

[0357] One SSB maps multiple PRACH resources;

[0358] One SSB maps one PRACH resource;

[0359] Multiple SSBs map one PRACH resource;

[0360] Multiple SSBs map multiple PRACH resources.

[0361] That is, there are two mapping relationships between SSB and PRACH resource: one SSB and PRACH resource mapping relationship, and multiple SSBs and PRACH resource mapping relationship. In the multiple SSBs and PRACH resource mapping relationship, the multiple SSBs include SSBs suitable for joint beams.

[0362] In some embodiments, the third synchronization signal block and the fourth synchronization signal block are mapped in different first resources. The third synchronization signal block includes SSBs suitable for joint beams, and the fourth synchronization signal block includes SSBs suitable for single beams. For example, the SSBs suitable for joint beams include one or more SSBs of single beams. The first resource includes PRACH resource. For example, in the SSBs suitable for single beams, one SSB maps the PRACH resource according to a first proportion; in the SSBs suitable for joint beams, one SSB group maps the PRACH resource according to a second proportion. In some embodiments, the first proportion and the second proportion can have different values. In some embodiments, the first proportion and the second proportion have the same value. The values of the first proportion and / or the second proportion are determined by a high-layer parameter.

[0363] For example, for SSBs suitable for single beams, the mapping of all transmitted SSBs suitable for single beams to PRACH resource is called a round of first mapping cycle. For SSBs suitable for joint beams, the mapping of all transmitted SSBs suitable for joint beams to PRACH resource is called a round of second mapping cycle. The first mapping cycle and the second mapping cycle are independent of each other, and the two mapping cycles have different association periods; or the two mapping cycles have the same association mode period; or the two mapping cycles have different association mode periods.

[0364] For example, the first mapping cycle and the second mapping cycle have an association relationship. For example, the first mapping cycle and the second mapping cycle form a third mapping cycle.

[0365] The third mapping cycle is associated with an association period; or the third mapping cycle is associated with an association mode period.

[0366] For example, the first mapping cycle and the second mapping cycle are independent of each other. For example, M1 times of the first mapping cycle is followed by an association period. M1 is an integer greater than or equal to 1. For example, M2 times of the second mapping cycle is followed by an association period. M2 is an integer greater than or equal to 1.

[0367] In some embodiments, the mapping of SSBs suitable for single beams to PRACH resource and / or the mapping of SSBs suitable for joint beams to PRACH resource is triggered by a first condition.

[0368] Exemplarily, the first condition comprises a timer invalidation. For example, when the timer is valid, the SSB-to-PRACH resource mapping is adapted to the single-beam SSB-to-PRACH resource mapping; after the timer is invalid, the SSB-to-PRACH resource mapping comprises the single-beam SSB-to-PRACH resource mapping and the joint-beam SSB-to-PRACH resource mapping; or, after the timer is invalid, the SSB-to-PRACH resource mapping is adapted to the joint-beam SSB-to-PRACH resource mapping.

[0369] Exemplarily, the first condition further comprises that the first node receives second signaling. The second signaling comprises DCI signaling or MAC CE signaling. For example, when the first node does not receive the second signaling, the SSB-to-PRACH resource mapping is adapted to the single-beam SSB-to-PRACH resource mapping; after the first node receives the second signaling, the SSB-to-PRACH resource mapping comprises the single-beam SSB-to-PRACH resource mapping and the joint-beam SSB-to-PRACH resource mapping; or, after the first node receives the second signaling, the SSB-to-PRACH resource mapping comprises the joint-beam SSB-to-PRACH resource mapping.

[0370] Or, when the first node does not receive the second signaling, the SSB-to-PRACH resource mapping is adapted to the joint-beam SSB-to-PRACH resource mapping; after the first node receives the second signaling, the SSB-to-PRACH resource mapping comprises the single-beam SSB-to-PRACH resource mapping and the joint-beam SSB-to-PRACH resource mapping; or, after the first node receives the second signaling, the SSB-to-PRACH resource mapping comprises the single-beam SSB-to-PRACH resource mapping.

[0371] Exemplarily, the second signaling comprises a mapping relationship between the synchronization block and the PRACH occasion. The mapping relationship between the synchronization block and the PRACH occasion comprises mapping indication information, used for switching the mapping relationship between the synchronization signal block and the PRACH occasion. For example, the SSB and the PRACH resource are mapped as the SSB and the PRACH resource mapping suitable for a single beam and / or the SSB and the PRACH resource mapping suitable for a joint beam. Exemplarily, the mapping indication information is 1 bit. When the indication information takes a first value, it indicates that the SSB and the PRACH resource are mapped as the SSB and the PRACH resource mapping suitable for a joint beam; when the indication information takes a second value, it indicates that the SSB and the PRACH resource are mapped as the SSB and the PRACH resource mapping suitable for a single beam. In some embodiments, when the indication information takes the first value, it indicates that the SSB and the PRACH resource are mapped as the SSB and the PRACH resource mapping suitable for a single beam and the SSB and the PRACH resource mapping suitable for a joint beam. When the indication information takes the second value, it indicates that the SSB and the PRACH resource are mapped as the SSB and the PRACH resource mapping suitable for a single beam.

[0372] For example, when the mapping indication information in the second signaling is '1', the SSB and the PRACH resource are mapped as the SSB and the PRACH resource mapping suitable for a single beam and the SSB and the PRACH resource mapping suitable for a joint beam. When the mapping indication information in the second signaling is '0', the SSB and the PRACH resource are mapped as the SSB and the PRACH resource mapping suitable for a single beam.

[0373] Exemplarily, the first condition comprises that the first node transmits first information. The first information is transmitted through the PUSCH, for example, reported through MSG3, reported through uplink (UL) auxiliary information.

[0374] Exemplarily, the first condition comprises that the first node transmits first information. The first information is transmitted through the PUCCH. For example, reported through uplink control information.

[0375] The first information includes trigger information of the specified synchronization signal block configuration. Illustratively, the trigger information of the synchronization signal block configuration includes mapping indication information. In some embodiments, the mapping indication information is 1 bit. When the indication information takes a first value, it indicates that the SSB and PRACH resource mapping is applicable to the joint beam SSB and PRACH resource mapping; when the indication information takes a second value, it indicates that the SSB and PRACH resource mapping is applicable to the single beam SSB and PRACH resource mapping. In some embodiments, when the indication information takes the first value, it indicates that the SSB and PRACH resource mapping is applicable to the single beam SSB and PRACH resource mapping and the joint beam SSB and PRACH resource mapping. When the indication information takes the second value, it indicates that the SSB and PRACH resource mapping is applicable to the single beam SSB and PRACH resource mapping.

[0376] For example, when the reported mapping indication information is "1", the SSB and PRACH resource mapping is applicable to the single beam SSB and PRACH resource mapping and the joint beam SSB and PRACH resource mapping. When the reported mapping indication information is "0", the SSB and PRACH resource mapping is applicable to the single beam SSB and PRACH resource mapping.

[0377] In some embodiments, the SSB and PRACH resource mapping applicable to the single beam is performed first, and then the SSB and PRACH resource mapping applicable to the joint beam is performed.

[0378] In some embodiments, the SSB and PRACH resource mapping applicable to the joint beam is performed first, and then the SSB and PRACH resource mapping applicable to the single beam is performed.

[0379] In some embodiments, the SSB and PRACH resource mapping applicable to the single beam and the SSB and PRACH resource mapping applicable to the joint beam can be determined by pre-configuration.

[0380] Exemplarily, the SSB burst set in the SSB configuration includes 4 SSB signals. A single SSB signal is an SSB signal applicable to a single beam, and an SSB signal applicable to a joint beam is an SSB signal set, which is a subset of an SSB burst set. For example, an SSB signal set SSBG1 is {SSB1.1, SSB1.2}, and SSBG2 is {SSB1.3, SSB1.4}. Assuming that there is a PRACH resource configuration as shown in FIG. 11, assuming that the mapping relationship between the SSB applicable to the single beam and the PRACH resource is 1 SSB maps 1 PRACH resource, and the mapping relationship between the SSB applicable to the joint beam and the PRACH resource is 1 SSB signal set maps 2 PRACH resources, the mapping relationship is shown in FIG. 11, SSB1.1, SSB1.2, SSB1.3, and SSB1.4 respectively map one PRACH resource; SSBG1 maps 2 PRACH resources, and SSBG2 maps 2 PRACH resources.

[0381] In some embodiments, the first condition includes that the first criterion is satisfied. Exemplarily, the SSB signal applicable to the joint beam is an SSB signal set, and the SSB-PRACH mapping of the SSB signal set needs to be determined according to the first criterion. The first criterion is that all the SSB signals applicable to the joint beam in the SSB signal set are greater than or equal to a channel quality threshold.

[0382] Exemplarily, when the first criterion is satisfied, the SSB-PRACH mapping needs to be performed on the SSB signal applicable to the joint beam. When the first criterion is not satisfied, the SSB-PRACH mapping does not need to be performed on the SSB signal applicable to the joint beam.

[0383] In some embodiments, part of the SSB signals in an SSB burst set and part of the PRACH resources have an association relationship, which is determined by a high-layer parameter.

[0384] Exemplarily, as shown in FIG. 11, an SSB burst set includes 4 SSB signals: SSB1.1, SSB1.2, SSB1.3, and SSB1.4. The PRACH resource includes 8 PRACH occasions. SSB1.1 and SSB1.2 are associated with the first 4 PRACH occasions, indicating that SSB1.1 and SSB1.2 can only be mapped on the first 4 PRACH occasions. SSB1.3 and SSB1.4 are associated with the last 4 PRACH occasions, indicating that SSB1.3 and SSB1.4 can only be mapped on the last 4 PRACH occasions.
