[0027] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure.

[0030] Currently, in mobile communication systems, some periodically transmitted public signals consume some of the network's energy and reduce the network's sleep frequency, resulting in increased network energy consumption. Therefore, how to transmit public signals and reduce network energy consumption is a technical problem that needs to be solved urgently.

[0031] Based on this, the present disclosure provides a signaling sending method and a signaling receiving method. By transmitting a first signaling signal through first configuration information to trigger the transmission of a common signal, the present disclosure reduces unnecessary common signal transmission and lowers network energy consumption. Furthermore, by reducing unnecessary common signal transmission, the network's sleep opportunities are increased, further reducing network energy consumption.

[0032] The signaling sending method and signaling receiving method provided by the present disclosure can be applied to a communication system as shown in Figure 1 , which shows a schematic diagram of the architecture of a communication system according to some embodiments.

The first node 10 can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, 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 care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the application scenarios.

[0035] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not restricted. In addition to the devices shown in Figure 1, the communication system may also include other devices (such as core network devices).

[0036] 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 intended 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. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0037] Fig. 2 shows a schematic flow chart of a signaling sending method according to some embodiments, which is applied to a first node. As shown in Fig. 2 , the method includes S101 to S102.

[0038] S101: Receive first configuration information.

[0039] In some embodiments, the first node receives the first configuration information on the first cell or on a second cell associated with the first cell.

[0040] The second cell satisfies at least one of the following conditions: the second cell is a reference cell of the first cell, the second cell is the first cell or a cell configured by the first configuration information, the second cell is an adjacent cell of the first cell, the coverage of the second cell overlaps with the coverage of the first cell, the second cell and the first cell are in the same frequency range, and there is system information block 1 SIB1 transmission on the second cell.

[0041] In this way, the first node can receive the first configuration information in the second cell associated with the first cell, which can increase the ways for the first node to obtain the first configuration information and improve the reliability of the first node receiving the first configuration information. When the first cell cannot provide the first configuration information, the first node can also obtain the first configuration information.

[0042] In some embodiments, the first configuration information includes at least one of the following: random access configuration information on the first cell, random access configuration information on the second cell, configuration information of the first signaling, a transmission mode of a common signal, and a transmission resource of a control channel for scheduling SIB1.

[0043] Exemplarily, the transmission mode of the common signal includes at least one of the following: periodic transmission, transmission N times, or transmission within a period of time. N is a positive integer and can be a predefined value, configured by a higher layer, configured by a SIB, or indicated by first configuration information. The period of time can be a predefined time, configured by a higher layer, configured by a SIB, or indicated by first configuration information.

[0044] In this way, by determining the transmission mode and transmission resources of the public signal, it can be ensured that the first node detects the public signal on the accurate time-frequency resources, avoiding additional power consumption caused by unnecessary blind detection, and can also indirectly control the transmission of the public signal by controlling the transmission of the first signaling through the relevant configuration information carried, thereby ensuring the effectiveness of the public signal transmission and improving the energy saving effect of the system.

[0045] In some embodiments, the first configuration information is carried by at least one of the following: a master information block (MIB) of the first cell, a master information block of the second cell, an SIB of the second cell, and a radio resource control (RRC) message of the second cell.

[0046] In this way, the first configuration information can be carried in multiple ways, which can improve the flexibility of the first configuration information. In addition, the MIB and SIB are broadcast information with high reliability, which can ensure the reliable transmission of the first configuration information. The RRC message can carry more information content, which can ensure the accuracy of the first configuration information.

[0047] S102: Send first signaling based on the first configuration information.

[0048] The first signaling is used to trigger transmission / stop transmission of a common signal on the first cell and / or initiate an initial access procedure on the first cell.

[0049] Exemplarily, the first signaling is used to trigger the transmission of a common signal on the first cell. Alternatively, the first signaling is used to trigger the cessation of transmission of a common signal on the first cell. Alternatively, the first signaling is used to trigger the transmission of a common signal on the first cell and is used to initiate an initial access process on the first cell. Alternatively, the first signaling is used to trigger the initiation of an initial access process on the first cell. The initial access process may be a four-step initial access process, in which msg1 in the four-step initial access process is carried in the first signaling. Alternatively, the initial access process may also be a two-step initial access process, in which msgA in the two-step initial access process is carried in the first signaling. The common signal includes at least one of the following: a synchronization signal block (SSB), a system information block 1 (SIB1), and other system information (OSI).

[0050] As an implementation manner, the first node transmits the first signaling in the first cell based on the first configuration information.

[0051] The transmission timing of the first signaling is the same as the random access channel occasion (RO) on the first cell.

[0052] Exemplarily, all random access channel opportunities on the first cell may be used for transmission of the first signaling. Alternatively, all valid random access channel opportunities on the first cell are applicable to transmission of the first signaling. Alternatively, the first node selects an appropriate random access channel opportunity from among the random access channel opportunities on the first cell based on the random access configuration information on the first cell carried in the first configuration information to transmit the first signaling.

[0053] In this way, when transmitting the first signaling in the first cell, the first node may select different random access channel opportunities according to different network conditions, so as to improve the flexibility of transmitting the first signaling.

[0054] As another implementation manner, the first node transmits the first signaling in the second cell based on the first configuration information.

[0055] The configuration information of the first signaling carried by the first configuration information can reuse the random access configuration information on the second cell carried by the first configuration information. In this way, network design and management can be simplified by reusing the random access configuration information on the second cell.

[0056] In some embodiments, the transmission timing of the first signaling includes at least one of the following: a random access channel timing RO of the first cell or the second cell, a random access channel timing with a specific index, a random access channel timing with a specific frequency domain resource, a random access channel timing within the Ath random access channel period in the random access channel association period, and a random access channel timing within the Bth SSB mapping period in the random access channel association period.

[0057] A is predefined, or A is determined by a high-level parameter, or A is indicated by the first configuration information, and A is a non-negative integer; B is predefined, or B is determined by a high-level parameter, or B is indicated by the first configuration information, and B is a non-negative integer.

[0058] Exemplarily, the transmission timing of the first signaling is a random access channel occasion (RACH occasion, RO) of the first cell or the second cell. For example, the transmission timing of the first signaling is a subset of the random access channel occasions of the first cell or the second cell. For example, when the first signaling is received and sent on the first cell, the transmission timing of the first signaling is a subset of the random access channel occasions of the first cell. When the first signaling is received and sent on the second cell, the transmission timing of the first signaling is a subset of the random access channel occasions of the second cell.

[0059] In another example, the transmission timing of the first signaling is a random access channel timing with a specific index.

[0060] As an implementation, the specific index is predefined. For example, the first random access channel opportunity of each random access cycle is used as the transmission opportunity for the first signaling. Alternatively, random access channel opportunities with even-numbered indices are used as the transmission opportunities for the first signaling. Alternatively, random access channel opportunities with odd-numbered indices are used as the transmission opportunities for the first signaling. Alternatively, the first X random access channel opportunities of each random access cycle are used as the transmission opportunities for the first signaling, where X is a predefined value or is configurable.

[0061] As another implementation, the specific index is an index that satisfies a preset condition. For example, the preset condition may be m mod N = 0. m is an index of a transmission opportunity that can be used for the first signaling, and N is an integer. N is predefined, determined by a higher-layer parameter, or indicated by the first configuration information.

[0062] In another example, the transmission timing of the first signaling is a random access channel timing with specific frequency domain resources. For example, the transmission timing of the first signaling may be a random access channel timing with a minimum frequency domain resource starting position. Alternatively, the transmission timing of the first signaling may be a random access channel timing that is offset from PRB0 by a first offset. The first offset may be predefined, determined by a higher-layer parameter, or indicated by first configuration information.

[0063] In another example, the transmission timing of the first signaling is a random access channel timing in the Ath random access channel cycle in the random access channel association cycle. For example, the transmission timing of the first signaling is a random access channel timing in the first random access channel cycle in the random access channel association cycle. Alternatively, the transmission timing of the first signaling is a random access channel timing in the last random access channel cycle in the random access channel association cycle.

[0064] In another example, the transmission timing of the first signaling is the random access channel timing within the Bth SSB mapping period in the random access channel association period. For example, the transmission timing of the first signaling is the transmission timing of the random access channel within the first SSB mapping period in the random access channel association period. Alternatively, the transmission timing of the first signaling is the transmission timing of the random access channel within the last SSB mapping period in the random access channel association period. Alternatively, the transmission timing of the first signaling is the random access channel timing remaining after an integer number of mapping periods of SSB and random access channel opportunities in the random access channel association period.

[0065] In this way, using specific transmission timings can reduce collisions between first signaling messages, thereby improving reception efficiency. By limiting the transmission of first signaling messages to specific transmission timings, random access channel resources can be more efficiently utilized. By transmitting first signaling messages at specific transmission timings, the receiver can also predict the time of receipt of the first signaling message based on the specific transmission timings, thereby improving signaling reliability. Using specific transmission timings can also ensure that the receiver can accurately identify the purpose of the received signaling, thereby improving signaling accuracy.

[0066] In some embodiments, the transmission timing of the first signaling is a random access channel timing determined by a new random access channel pattern for base station energy conservation. It should be noted that the new random access channel pattern is a pattern used to improve base station energy conservation efficiency, and transmitting the first signaling using the random access channel timing determined by the new pattern can also achieve the effect of reducing energy consumption.

[0067] In some embodiments, the transmission timing of the first signaling and the SSB satisfy an ascending mapping relationship within the random access channel association period.

[0068] The transmission timing of the first signaling and the SSB are mapped in ascending order according to the index of the transmission timing of the first signaling within the random access channel association period.

[0069] Exemplarily, as shown in FIG3 , there are three PRACH configuration periods in a physical random access channel (PRACH) association period, and each of the three PRACH configuration periods includes three random access channel opportunities (RO), namely RO1, RO2 and RO3. The transmission timing of the first signaling may be the first random access channel opportunity (RO) in the three PRACH configuration periods. The indexes of the transmission timings of the first signaling corresponding to the three random access channel opportunities for the first signaling transmission are 1, 2, and 3, respectively. In the case of a one-to-one mapping of the SSB and the transmission timing of the first signaling, the transmission timing 1 of the first signaling is associated with the index of the first actually transmitted SSB, the transmission timing 2 of the first signaling is associated with the index of the second actually transmitted SSB, and the transmission timing 3 of the first signaling is associated with the index of the third actually transmitted SSB.

[0070] In some embodiments, the configuration information of the first signaling carried by the first configuration information is a subset of the random access configuration information. Thus, by using the subset of the random access configuration information as the configuration information of the first signaling, no separate configuration is required, thereby reducing design cost and power consumption.

[0071] In some embodiments, the configuration information of the first signaling includes at least one of the following: the configuration index of the first signaling, the starting position of the frequency domain resources of the first signaling, the number of times the first signaling is frequency-division multiplexed on the same time domain resources, the receiving power of the first signaling, the power increase value of the first signaling, the mapping relationship between the first signaling and the SSB, the signaling index of the first signaling, the format of the first signaling, and the first signaling association period.

[0072] In this way, the configuration information of the first signaling can simplify the configuration process and improve the sending efficiency of the first signaling. In addition, the relevant content carried by the configuration information of the first signaling can optimize resource utilization, improve spectrum efficiency, and improve reliability.

[0073] In some embodiments, the configuration index of the first signaling carried in the first signaling configuration information is associated with at least one of the following: the format of the first signaling, the configuration period of the first signaling, the radio frame number including the transmission opportunity of the first signaling, the subframe number of the transmission opportunity of the first signaling, the starting symbol index of the transmission opportunity of the first signaling, and the duration of the transmission opportunity of the first signaling. In this way, by associating the configuration index of the first signaling with the relevant configuration parameters, configuration can be simplified, configuration flexibility and scalability can be improved, and the access process can be optimized.

[0074] In some embodiments, the configuration index of the first signaling carried by the first signaling configuration information is determined according to at least one of the following: predefined, the format of the first signaling, and the configuration period of the first signaling.

[0075] In other embodiments, the configuration index of the first signaling carried in the first signaling configuration information is one of a configuration index table of the first signaling. The configuration index table of the first signaling is a subset of a random access configuration index table. Alternatively, the configuration index of the first signaling is a subset of a random access configuration index. The configuration index of the first signaling is determined based on at least one of: a predefined value, a format of the first signaling, and a configuration periodicity of the first signaling.

[0076] In some embodiments, the value of the configuration index of the first signaling is related to at least one of the following: the function of the first signaling, the frequency range of the first cell, and the spectrum type. The frequency range can be FR1 or FR2, and the spectrum type can be paired spectrum, supplementary uplink spectrum, unpaired spectrum, etc. For example, the value of X corresponding to the paired spectrum in the frequency range FR1 is greater than or equal to 256. The value of X corresponding to the unpaired spectrum in the frequency range FR1 is greater than or equal to 263. The value of X corresponding to the frequency range FR2 is greater than or equal to 256.

[0077] It should be noted that FR1 and FR2 represent different frequency bands that can be used in mobile communication systems. For example, FR1 represents the frequency band below 6 GHz, while FR2 represents the millimeter wave frequency band above 24 GHz.

[0078] In this way, by limiting the configuration index of the first signaling through multiple attributes, it is possible to simplify the configuration, optimize the access process, and improve reliability and flexibility.

[0079] In some embodiments, the first signaling does not support frequency division multiplexing. Thus, since the first signaling does not support frequency division multiplexing, the spectrum associated with the first signaling can be released for other purposes (such as user data transmission, etc.), thereby improving spectrum efficiency.

[0080] In some embodiments, the mapping relationship between the first signaling and the SSB includes at least one of the following: the number of SSB indexes corresponding to each transmission opportunity of the first signaling, and the number of first signaling indexes corresponding to each SSB index.

[0081] In some embodiments, the association period of the first signaling includes one or more configuration periods of the first signaling. Within the association period of the first signaling, at least one transmission opportunity of the first signaling is associated with the SSB actually transmitted.

[0082] In this way, by managing the mapping of the first signaling and the SSB, or by defining the association period of the first signaling to include one or more configuration periods, and determining that there is at least one transmission opportunity of the first signaling associated with the actually transmitted SSB, the transmission reliability can be improved and it is ensured that there is a first signaling transmission opportunity that can be used for transmission in each beam direction.

[0083] In some embodiments, the first signaling is a random access preamble sequence. Alternatively, the first signaling is an uplink sequence generated based on the random access preamble sequence. Thus, defining the first signaling as a random access preamble sequence or an uplink sequence generated based on the random access preamble sequence can reduce the complexity of the first signaling and improve the robustness and versatility of the first signaling.

[0084] In some embodiments, the first signaling is associated with a signaling index, and the signaling index is determined according to at least one of the following: a predefined value, and the first configuration information. The signaling index is a random access preamble index / identifier (preamble ID).

[0085] Exemplarily, the signaling index of the first signaling is greater than 63. For example, when the base station detects that the index of the random access preamble sequence is greater than 63, it determines that the preamble sequence is the first signaling. When the base station detects that the index of the random access preamble sequence is less than or equal to 63, it determines that the preamble sequence is not the first signaling, and the preamble sequence is for initiating a random access procedure.

[0086] In another example, the value range of the signaling index of the first signaling is an integer greater than or equal to 0 and less than or equal to 63. The signaling index of the first signaling is indicated by the first configuration information.

[0087] In this way, the first signaling is associated with the signaling index, and the signaling index is determined according to the predefined value or the first configuration information, which can simplify the detection process, support flexible access strategies, and enhance security.

[0088] In some embodiments, the first signaling is generated based on at least one of the following: a specified RACH preamble format, a specified RNTI, a physical cell ID of the first cell, a first signaling length, a physical index value of a root sequence of the first signaling, a logical index value of a root sequence of the first signaling, and a first signaling index value. Generating the first signaling based on specific parameters can improve reliability, support flexible access policies, and enhance security.

[0089] In some embodiments, when a resource conflict occurs between the first signaling and other signaling, the signaling to be transmitted first is determined based on the priority of the first signaling and the priority of the other signaling.

[0090] The priority of the first signaling is a preset value or can be configured by a higher-layer parameter. For example, if the first signaling conflicts with other signaling transmitted on the physical random access channel, if the priority of the first signaling is higher than that of the other signaling, the first signaling is transmitted first. If the priority of the first signaling is lower than that of the other signaling, the other signaling is transmitted first.

[0091] In this way, by resolving resource conflicts through the priority of the first signaling, reliable transmission of key signaling, ie, signaling with a higher priority, can be effectively ensured, and flexibility in transmission of the first signaling can also be improved.

[0092] In some embodiments, the function of the first signaling is determined according to at least one of the following: predefinition, transmission timing of the first signaling, time domain resources of the first signaling, frequency domain resources of the first signaling, signaling index of the first signaling, and generation method of the first signaling.

[0093] For example, the function of the first signaling is predefined as an example. The first signaling is used to trigger the public signal transmission. Alternatively, the first signaling is used to trigger the public signal transmission and initiate the initial access process.

[0094] In another example, the function of the first signaling is determined based on the transmission timing of the first signaling. When the transmission timing of the first signaling satisfies condition A, the first signaling is used to trigger the transmission of the common signal. Otherwise, the first signaling is used to trigger the transmission of the common signal and initiate the initial access procedure. Condition A is predefined, for example, condition A is that the transmission timing index of the first signaling is equal to 1.

[0095] In another example, taking the case where the function of the first signaling is determined based on the frequency domain resources of the first signaling, when the first signaling does not use frequency division multiplexing, the first signaling is used to trigger public signal transmission. When the first signaling supports frequency division multiplexing, the first signaling is used to trigger public signal transmission and initiate an initial access procedure.

[0096] In another example, the function of the first signaling is determined based on the signaling index of the first signaling. When the signaling index of the first signaling is less than or equal to 63, the first signaling is used to initiate the initial access procedure. When the signaling index of the first signaling is greater than 63, the first signaling is used to trigger the transmission of a common signal.

[0097] In this way, running the function of configuring the first signaling according to demand can improve the flexibility and scalability of the first signaling, and when adjusting the function according to the transmission timing and time-frequency domain resources, it can also optimize resources and improve the reliability of the first signaling transmission.

[0098] In some embodiments, after sending the first signaling, the first node detects feedback information of the first signaling at a first moment. The feedback information includes at least one of the following: confirmation of successful transmission, confirmation of failure to transmit, confirmation of transmission of a common signal, confirmation of stopping transmission of a common signal, and random access response information.

[0099] Exemplarily, the feedback information may be downlink control information scrambled by a specified radio network temporary identifier (RNTI). The RNTI may be determined based on at least one of: predefined, a symbol index of the transmission timing of the first signaling, a time slot index of the transmission timing of the first signaling, a frequency domain index of the transmission timing of the first signaling, and a carrier index of the transmission timing of the first signaling. The feedback information may be carried by SIB1, and the feedback information may be random access response information. After the first node receives the feedback information carried by SIB1, the first node decodes the random access response information.

[0100] As an implementation method, the first moment is determined according to at least one of the following: a predefined time offset, a high-level configuration, the first configuration information, the transmission timing of the first signaling, the transmission time of the system information block 1 SIB1, the transmission period of the system information block 1 SIB1, the physical downlink control channel (PDCCH) common search space (CSS) type 0 control resource set (CORESET), and the physical downlink control channel common search space type 1 control resource set.

[0101] For example, the first moment is determined based on the transmission timing of the first signaling and a predefined time offset. The predefined time offset is the time offset between the first transmission timing of the first signaling and the first moment. The predefined time offset is the time offset between the last transmission timing of the first signaling and the first moment. For example, the last transmission timing of the first moment is X milliseconds away from the transmission time of the first signaling, where X ≥ 0.

[0102] As another example, the first time instant is determined based on the transmission time of system information block 1 (SIB1). The first time instant begins at the symbol next to the first SIB1 transmission end time after the first signaling. Alternatively, the first time instant begins at the symbol next to the first SIB1 transmission end time after the first signaling. Alternatively, the first time instant begins at the first symbol of the earliest CORESET configured to receive PDCCH CSS Type 1 after the Nth SIB1 transmission end time, where N ≥ 1.

[0103] In another example, the first moment may be after the first signaling is sent, when the first node is configured to receive the first symbol of the earliest control resource set of the PDCCH CSS type 1.

[0104] As another example, the first moment is determined based on the transmission period of system information block 1 (SIB1). The first moment is the first slot (time slot) after N SIB1 transmission periods after the transmission timing of the first signaling. Alternatively, the first moment is the start of the first symbol of the earliest control resource set configured to receive PDCCH CSS type 1 after N SIB1 transmission periods after the transmission timing of the first signaling. The transmission timing of the first signaling can be the first transmission timing or the last transmission timing of the first signaling.

[0105] In some embodiments, after sending the first signaling, the first node detects the feedback information within a first detection window. The starting point of the first detection window is the first moment, and the time length of the first detection window is L, where L is a positive integer.

[0106] As an implementation manner, the length L of the first detection window is determined according to at least one of the following: a predefined length, a high-layer parameter configuration, and a first information indication.

[0107] In this way, after sending the first signaling, the first node detects the feedback information at a specific time point and determines the first moment and the detection mechanism according to specific standards, which can effectively improve reliability and optimize resources.

[0108] In some embodiments, after sending the first signaling, the first node detects feedback information about the first signaling. This allows the first node to ensure that the second node successfully received the first signaling by detecting the feedback information. Furthermore, the feedback information may include relevant information about the transmission of the first signaling, such as channel quality. The first node can adjust transmission parameters based on the feedback information to optimize subsequent signaling transmissions.

[0109] In some embodiments, after sending the first signaling, the first node detects the common signal and / or downlink control information (DCI) that schedules the common signal.

[0110] In this way, after sending the first signaling, by detecting the common signal, it is confirmed whether the common signal transmission on the first cell is successfully triggered, and by scheduling the DCI of the common signal, the transmission of the common signal can be coordinated to avoid conflicts.

[0111] As an implementation, the application delay of the first signaling may be a predefined value, or may be determined based on at least one of the following: an indication of the first configuration information, and a subcarrier spacing of the first cell. The starting position of the application delay includes at least one of the following: the time when the first signaling transmission is transmitted, the time when the first signaling transmission ends, and the time when the first signaling feedback information is received.

[0112] Exemplarily, the transmission timing of the common signal is no earlier than the application delay. After sending the first signaling, the first node detects the common signal or the DCI scheduling the common signal after the application delay.

[0113] In this way, by delaying the detection of the common signal and / or the DCI for scheduling the common signal when sending the first signaling interval application, it is possible to ensure that there is sufficient time to trigger the sending of the common signal, thereby ensuring that the common signal is successfully sent.

[0114] To facilitate understanding of the signaling sending method provided by the present disclosure, four complete examples of the signaling sending method are provided below.

[0115] Example 1: A first node receives first configuration information and sends a first signaling on a second cell based on the first configuration information. The configuration information of the first signaling is random access configuration information multiplexed on the second cell. The first signaling includes a random access preamble, and the signaling index of the first signaling is a preamble greater than 63. The generation of the first signaling is related to the physical cell identifier (physical cell identifier) ​​of the first cell. The second node detects the signaling index of the first signaling at a random access channel opportunity. When the first signaling is identified, the second node triggers the transmission of a public signal on the first cell by interacting with other nodes.

[0116] Example 2: The first node receives the first configuration information and sends the first signaling on the first cell based on the first configuration information. The first node obtains the random access configuration information of the first cell in the second cell, and sends the first signaling based on the random access configuration information of the first cell. The first node determines the time-frequency domain resources of the random access channel opportunity based on the random access configuration information of the first cell. The first node detects the SSB and selects the target SSB and the random access channel opportunity corresponding to the target SSB based on the detection result. The first node sends the first signaling on the random access channel opportunity corresponding to the target SSB. In addition, the first node detects the DCI of the common signal after applying a delay after sending the first signaling, and receives system information.

[0117] Example 3: The first node receives the first configuration information and sends the first signaling on the first cell based on the first configuration information. The first node uses the random access configuration information of the first cell to send the first signaling. The first node determines the time-frequency domain resources of the random access channel opportunity based on the random access configuration information of the first cell, and selects the random access channel opportunity that can be used for the first signaling transmission. The first node detects the SSB and selects the target SSB and the transmission timing of the first signaling corresponding to the target SSB based on the detection result. The first node sends the first signaling at the transmission timing of the first signaling corresponding to the target SSB. In addition, the first node detects the DCI of the common signal after applying a delay after sending the first signaling, and receives the system information.

[0118] Example 4: A first node receives first configuration information and, based on the first configuration information, sends first signaling on a first cell. The first node uses the random access configuration information of the first cell to determine a transmission timing for the first signaling. The first node detects an SSB and, based on the detection result, selects a target SSB and a transmission timing for the first signaling corresponding to the target SSB. The first node sends the first signaling at the transmission timing for the first signaling corresponding to the target SSB.

[0119] In this way, by transmitting the first signaling through the first configuration information to trigger the transmission of the common signal, unnecessary common signal transmission can be reduced, thereby reducing network energy consumption. Furthermore, by reducing unnecessary common signal transmission, the opportunity for network dormancy can be increased, further reducing network energy consumption.
