[0028] To enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0029] 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 article is merely a description of the association relationship of associated objects, indicating that there can be three 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 "a plurality" means two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0030] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0031] The transmission of public signals consumes a significant portion of base station energy. Therefore, reducing public signal transmission is a key approach to reducing base station energy consumption. However, simply modifying the public signal configuration to an energy-efficient configuration—for example, increasing the public signal transmission period or reducing the public signal beam coverage—can significantly impact system performance and user experience. Therefore, how to transmit public signals while reducing base station energy consumption while ensuring system performance and user experience is an urgent issue.

[0032] Based on this, the present disclosure provides a public signal processing method. In the above method, the public signal configuration can be determined according to the first condition, and then the public signal can be detected or transmitted based on the public signal configuration, thereby realizing adaptive adjustment of public signal transmission or detection, thereby reducing base station energy consumption while ensuring system performance and user experience.

[0033] The common signal processing 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 provided by an embodiment of the present disclosure.

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.

[0036] 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 limited.

[0037] 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. Those skilled in the art will appreciate 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 equally applicable to similar technical problems.

[0038] FIG2 shows a flow chart of a common signal processing method provided by the present disclosure. As shown in FIG2 , the common signal processing method is applied to the first node 10 in FIG1 , and includes the following S101 - S102 .

[0039] S101. Determine a common signal configuration according to a first condition.

[0040] The first condition includes at least one of the following: first signaling, timer, terminal type, and terminal capability. The first signaling includes at least one of the following: radio resource control (RRC) signaling, system information, L1 signaling, and L2 signaling.

[0041] Exemplarily, the first signaling is transmitted or received in a primary cell (PCell) or a primary secondary cell (PSCell), and acts on at least one secondary cell (SCell).

[0042] In another exemplary embodiment, the first signaling is transmitted / received on the indicated cell. For example, the terminal receives the first signaling in the first cell, and the indication content of the first signaling is applied to the first cell. The first cell is a primary cell or a secondary cell.

[0043] In some embodiments, radio resource control (RRC) signaling is used to configure or update a common signal configuration; or, radio resource control (RRC) signaling is used to configure at least one set of common signal configurations, where the common signal configuration is one of the at least one set of common signal configurations.

[0044] Exemplarily, the common signal configuration is updated through RRC signaling reconfiguration. In response to receiving the RRC signaling, the target secondary cell adds the updated common signal configuration and applies the updated common signal configuration to achieve updated common signal configuration.

[0045] In another exemplary embodiment, RRC signaling configures at least one set of common signal configurations, and selects one set of common signal configurations from the at least one set of common signal configurations as the updated common signal configuration. Each set of common signal configurations in the at least one set of common signal configurations is associated with a common signal configuration index.

[0046] In some embodiments, one of the at least one common signal configurations configured by RRC signaling is a default common signal configuration.

[0047] Exemplarily, the default common signal configuration may be a common signal configuration with an associated common signal configuration index of 0. If no common signal configuration indication signaling is detected or the timer for the default common signal configuration does not expire, the first node detects a common signal according to the default common signal configuration. The common signal configuration indication signaling includes at least one of the following: a system information block (SIB1), L1 signaling, or L2 signaling.

[0048] In some embodiments, system information (SI) is used to configure or update a common signal configuration; or, the system information is used to configure at least one set of common signal configurations, where the common signal configuration is one of the at least one set of common signal configurations.

[0049] For example, the common signal configuration may be determined by SI. Alternatively, SI may be carried on SIB1, and the common signal configuration may also be determined by SIB1.

[0050] In another example, the SI may carry a common signal configuration update indication. Alternatively, the SI may directly carry the common signal configuration that needs to be updated.

[0051] The common signal configuration update indication may indicate an index associated with the common signal configuration, or may directly indicate the common signal configuration.

[0052] In the case where the SI configures at least one set of common signal configurations, each set of common signal configurations is associated with a common signal configuration index. In this case, the common signal configuration update indication carried by the SI can be used to indicate the index associated with the common signal configuration.

[0053] Exemplarily, when the common signal configuration update indication carried by the SI is used to indicate an index associated with the common signal configuration and is carried in SIB1, the first node finds through detection that the index of the currently used common signal configuration is inconsistent with the index of the common signal configuration carried by SIB1. The first node determines that the common signal configuration needs to be updated, and performs common signal detection according to the common signal configuration associated with the index of the common signal configuration carried by SIB1 from the first occasion.

[0054] When the common signal configuration update indication carried by the SI indicates the common signal configuration, the first node may directly detect the SI to determine the common signal configuration indicated by the SI. When the common signal configuration detected by the first node is inconsistent with the current common signal configuration, the first node determines that the common signal configuration needs to be updated. Starting from the first occasion, the first node performs common signal detection according to the common signal configuration carried by the SI.

[0055] In some embodiments, when the common signal configuration is updated, an SI change is generated. The first node detects the SI change. When the SI change is detected, the first node receives the SI, determines the updated common signal configuration based on the common signal configuration update indication carried in the SI, and performs common signal detection according to the updated common signal configuration from the first time.

[0056] For example, the first time may be the start time of a common signal change period, or the first time may be the start time of a next common signal configuration validity period.

[0057] In another example, the SI is SI transmitted on a primary cell (PCell), and the SI indicates that the updated common signal configuration is applied to the PCell.

[0058] In this way, by configuring or updating the common signal configuration through the SI, the communication system can more flexibly adapt to different network conditions. In addition, the SI can also directly carry the common signal configuration. The first node can directly detect the SI to determine whether the common signal configuration needs to be updated, which improves the efficiency of determining the common signal configuration.

[0059] In some embodiments, L1 signaling includes at least one of the following: a first bit field, a second bit field, a third bit field, a fourth bit field, and a fifth bit field.

[0060] The first bit field is used to indicate the index of the current common signal configuration or the common signal configuration associated with the current common signal configuration; the second bit field is used to indicate the index of the updated common signal configuration or the common signal configuration associated with the updated common signal configuration; the third bit field is used to indicate whether the common signal configuration is updated; the fourth bit field is used to indicate the physical random access channel (PRACH) configuration adaptation operation; the fifth bit field is used to indicate the paging occasion (PO) adaptation operation.

[0061] Exemplarily, when the first bit field is used to indicate the current common signal configuration, the first bit field may indicate all or part of the configuration of the current common signal configuration. For example, the first bit field may indicate the common signal transmission period in the current common signal configuration. For another example, the first bit field may indicate the common signal actually transmitted in the current common signal configuration. The first bit field may be presented in the form of a bitmap, the first bit field occupies multiple bits, and each of the multiple bits corresponds to the index of a common signal. When the bit is 0, it indicates that the common signal associated with the bit is not transmitted. Correspondingly, when the bit is 1, it indicates that the common signal associated with the bit is transmitted.

[0062] In another exemplary embodiment, when the first bit field can indicate all or part of the current common signal configuration, the first bit field can simultaneously indicate the common signal transmission period and the actually transmitted common signal in the current common signal configuration. For example, the first bit field can be divided into two parts. The first part is used to indicate the common signal transmission period in the current common signal configuration, and the second part is used to indicate the actually transmitted common signal in the previous common signal configuration.

[0063] It should be understood that when high-layer signaling (e.g., RRC signaling) or SI configures at least one set of common signal configurations, each set of common signal configurations in the at least one set of common signal configurations is associated with an index of a common signal configuration. In this case, the first bit field can be used to indicate the index of the common signal configuration associated with the current common signal configuration.

[0064] Exemplarily, when the second bit field is used to indicate the updated common signal configuration, the second bit field can be used to indicate all or part of the updated common signal configuration. For example, the second bit field can be used to indicate the common signal transmission period in the updated common signal configuration, which can also be referred to as the effective time of the updated common signal configuration. When the second bit field only indicates the common signal transmission period in the updated common signal configuration, the second bit field indicates that the updated common signal configuration is the same as the current common signal configuration except for the common signal transmission period, or both use the default common signal configuration. For another example, the second bit field can be used to indicate the index of the common signal actually transmitted in the updated common signal configuration. The second bit field can be presented in the form of a bitmap, which occupies multiple bits. Each bit in the multiple bits corresponds to the index of a common signal. When the bit is 0, it indicates that the common signal associated with the bit is not transmitted. Correspondingly, when the bit is 1, it indicates that the common signal associated with the bit is transmitted. For another example, the second bit field can simultaneously indicate the common signal transmission period in the updated common signal configuration and the index of the common signal actually transmitted in the updated common signal configuration. The second bit field can be divided into two parts. The first part is used to indicate the common signal transmission period in the updated common signal configuration, and the second part is used to indicate the index of the common signal actually transmitted in the updated common signal configuration.

[0065] It should be understood that when higher layer signaling (e.g., RRC signaling) or SI configures at least one set of common signal configurations, each common signal configuration in the at least one set of common signal configurations is associated with an index of a common signal configuration. In this case, the second bit field can be used to indicate the index of the common signal configuration associated with the updated common signal configuration.

[0066] Exemplarily, when the second bit field is used to indicate the index of the common signal configuration associated with the updated common signal configuration, starting from the effective time of the next common signal configuration, the current common signal configuration is updated to the common signal configuration associated with the index of the common signal configuration indicated by the second bit field.

[0067] It should be noted that the second bit field is used to indicate the index of the updated common signal configuration or the common signal configuration associated with the updated common signal configuration. The index of the updated common signal configuration or the common signal configuration associated with the updated common signal configuration can also be described as the index of the common signal configuration to be adopted or the common signal configuration associated with the common signal configuration to be adopted, which is not limited in this disclosure.

[0068] Exemplarily, the third bit field may occupy 1 bit. When the bit value is 1, it indicates that the common signal configuration has been updated. When the bit value is 0, it indicates that the common signal configuration has not been updated. For example, when the third bit field indicates that the common signal configuration has been updated, after the first node receives the updated common signal configuration, it detects the common signal according to the updated common signal configuration from the first time. The first time may be the start time of the next common signal cycle. Alternatively, the first time may also be the effective time or start time of the next common signal configuration validity period.

[0069] In another exemplary embodiment, when the third bit field indicates that the common signal configuration is updated and the common signal configuration information is carried on a physical downlink shared channel (PDSCH) (e.g., SIB1), the first node receives the PDSCH to obtain the updated common signal configuration, and detects the common signal according to the updated common signal configuration from the effective time of the next validity period of the common signal configuration.

[0070] Exemplarily, the fourth bit field is used to indicate that the PRACH configuration is adaptively adjusted according to the state of the network or channel. In this way, the communication system can better adapt to different network conditions and requirements, thereby improving the flexibility and performance of the system.

[0071] Exemplarily, the fifth bit field is used to instruct PO to perform adaptive adjustment according to the state of the network or channel, so that the communication system can better adapt to different network conditions and requirements, thereby improving the flexibility and performance of the system.

[0072] In this way, multiple bit fields carried in L1 signaling indicate different common signal configuration related functions, which can improve configuration flexibility and accuracy. In addition, the bit field can also indicate PRACH and PO adaptive adjustment, so that the communication system can adapt to different network conditions, which can improve flexibility and performance.

[0073] In some embodiments, the L1 signaling includes group common downlink control information (DCI) or cell specific downlink control information.

[0074] The search space set for L1 signaling includes at least one of the following: Type 2-physical downlink control channel common search space set (Type2-PDCCH CSS set), Type 2A-PDCCH common search space set (Type2A-PDCCH CSS set), and Type 3-PDCCH common search space set (Type3-PDCCH CSS set).

[0075] In one implementation, the L1 signaling is one of the DCI formats 2_X.

[0076] For example, for a terminal in a connected state, L1 signaling may be DCI format 2_6. The bit field associated with the common signal configuration is located after the sleep indication bit field of the secondary cell (SCell) in DCI format 2_6. Alternatively, the bit field associated with the common signal configuration is a bit field in a redefined DCI format 2_6, for example, a wake-up signal (WUS) and / or an SCell sleep indication bit field.

[0077] As another example, for a terminal in idle or inactive mode, L1 signaling may be DCI format 2_7. The bit field associated with the common signal configuration is located after the tracking reference signal (TRS) availability indication bit field in DCI format 2_7. Alternatively, the bit field associated with the common signal configuration is a bit field in a redefined DCI format 2_7, for example, a paging indication bit field and / or a TRS availability indication bit field. The validity period of the common signal configuration indicated by the bit field associated with the common signal configuration is consistent with the validity period of the TRS indicated in the TRS-related bit field in DCI format 2_7.

[0078] As another example, for a terminal in a connected state, the L1 signaling may be DCI format 2_9. The bit field related to the common signal configuration is a bit field in DCI format 2_9 or a newly added bit field.

[0079] In another example, the L1 signaling may be a paging DCI scrambled by a paging-radio network temporary identity (P-RNTI), or the L1 signaling may be a DCI format 1_0 scrambled by an SI-RNTI.

[0080] In this way, L1 signaling includes multiple search space sets, which can provide more flexible resource allocation and help meet different service requirements. In addition, L1 signaling can use different DCI formats based on different terminal states, which can more effectively utilize resources and improve configuration accuracy.

[0081] In some embodiments, the L2 signaling includes a first media access control control element (MAC CE).

[0082] The first MAC CE is a MAC CE used to activate / deactivate at least one secondary cell. For example, the first MAC CE may be a secondary cell activation / deactivation MAC CE or an enhanced secondary cell activation / deactivation MAC CE. The first MAC CE may also be referred to as a secondary carrier activation / deactivation MAC CE.

[0083] Exemplarily, the first MAC CE includes a reserved bit, and the reserved bit in the first MAC CE is used to indicate the common signal configuration. When the reserved bit R in the first MAC CE is 0, it indicates that the common signal configuration is the first common signal configuration. When the reserved bit R in the first MAC CE is 1, it indicates that the common signal configuration is the second common signal configuration.

[0084] In another exemplary embodiment, the common signal configuration indicated in the first MAC CE is only valid for a secondary cell that is activated or to be activated. Alternatively, the common signal configuration indicated in the first MAC CE is only valid during the secondary cell activation process. Alternatively, the common signal configuration indicated in the first MAC CE is always valid after the first MAC CE.

[0085] In this way, the first MAC CE limits the validity of the common signal configuration, which can improve the accuracy of the common signal configuration and ensure that the common signal configuration is adapted to the state or event of the specified secondary cell.

[0086] In some embodiments, the L2 signaling includes a Beam Failure Recovery MAC CE.

[0087] In some embodiments, the L2 signaling includes a second MAC CE.

[0088] The second MAC CE includes at least one of the following: a sixth bit field, a seventh bit field, an eighth bit field, a ninth bit field, and a reserved bit field. The sixth bit field is used to indicate activation or deactivation of at least one secondary cell; the seventh bit field is used to indicate activation or deactivation of a common signal configuration on at least one secondary cell; the eighth bit field includes an identifier of the secondary cell; and the ninth bit field includes an index of the common signal configuration of the secondary cell.

[0089] Exemplarily, the second MAC CE may carry the eighth bit field, the ninth bit field, and the reserved bit field at the same time. For example, as shown in FIG3 , FIG3 shows a schematic diagram of the structure of the second MAC CE. The second MAC CE includes multiple bytes, the eighth bit field occupies 5 bits of each byte in the multiple bytes, the ninth bit field occupies 2 bits of each byte in the multiple bytes, and the reserved bit field occupies 1 bit of each byte in the multiple bytes. The eighth bit field is used to indicate the serving cell ID (Serving cell ID) of the target cell. i ), the ninth bit field is used to indicate the index S of the common signal configuration on the target cell i .

[0090] In this way, the second MAC CE includes multiple bit fields, which can more flexibly configure the relevant parameters of the common signal configuration. In addition, the multiple bit fields can respectively implement different functions, further improving the configuration flexibility. By carrying multiple bit fields, the utilization rate of communication resources can also be improved.

[0091] In some embodiments, the first node detects the first signaling at least once within an application period associated with the common signal configuration.

[0092] Each common signal configuration is associated with an application period.

[0093] Illustratively, during the application period, the common signal configuration remains unchanged. The application period may be equal to the validity period of the common signal configuration. During the application period, the first node detects the first signaling at least once. The application period includes one or more first signaling monitoring opportunities.

[0094] It should be noted that, during the application period, the second node will not configure or transmit a different common signal configuration or common signal configuration update indication. Correspondingly, during the application period, the first node does not expect to receive a different common signal configuration or common signal configuration update indication.

[0095] In one implementation, the application period is associated with at least one of the following: a system information modification period, a default paging cycle, a discontinuous reception DRX cycle, an extended discontinuous reception e-DRX cycle, a TRS validity period, a common signal change period, and a PRACH association period.

[0096] In some other embodiments, the first node detects the first signaling within a detection time.

[0097] The detection time includes at least one of the following: a first wireless frame, a first detection window.

[0098] Exemplarily, the first radio frame satisfies at least one of the following:

[0099] odd frames;

[0100] Even frames;

[0101] (A+B) mod T = 0;

[0102] A mod T = 0.

[0103] A is a system frame number (SFN) of the second radio frame, B is a time offset, such as an RF (radio frame) offset, and T is a parameter configured or predefined by RRC.

[0104] In another exemplary embodiment, the first detection window includes at least one of the following: a starting point, an ending point, and a duration. The starting point and the ending point are associated with at least one of the following: a common signal, a PO, or a random access channel occasion (RO). For example, the ending point of the first detection window is spaced from the SSB by a first offset.

[0105] In this way, the first node can more flexibly control the reception and processing of the first signaling by detecting the first signaling within a specific time. In addition, detecting the first signaling only within a specific time can also reduce energy consumption and improve detection accuracy.

[0106] In some embodiments, the timer is associated with a common signal configuration.

[0107] The timer is used to indicate the update of the common signal configuration.

[0108] In one implementation, in response to a timer expiring, the common signal configuration is updated.

[0109] Exemplarily, when the first common signal configuration takes effect, a timer is started. When the timer times out, the common signal configuration is switched from the first common signal configuration to the second common signal configuration. When the timer times out, the first node detects the common signal based on the second common signal configuration. Alternatively, the first common signal configuration is not associated with the timer, and the second common signal configuration is associated with the timer. When the first common signal configuration takes effect, the timer is not started. When the second common signal configuration takes effect, the timer is started, and when the timer times out, the common signal configuration is switched from the second common signal configuration to the first common signal configuration. The first common signal configuration is the default common signal configuration, and the second common signal configuration is the non-default common signal configuration.

[0110] In another exemplary embodiment, the first common signal configuration is associated with a timer. When the first common signal configuration takes effect, the timer is started. When the timer times out, the common signal configuration is switched from the first common signal configuration to the second common signal configuration. The first common signal configuration is a default common signal configuration, and the second common signal configuration is a non-default common signal configuration.

[0111] In another exemplary embodiment, the timer may include multiple timers, such as a first timer, a second timer, ..., an Nth timer, etc., where N is a positive integer. The first common signal configuration may be associated with the first timer, and the second common signal configuration may be associated with the second timer. When the first common signal configuration takes effect, the first timer is started. When the first timer times out, the common signal configuration is switched from the first common signal configuration to the second common signal configuration. And when the second common signal configuration takes effect, the second timer is started. When the second timer times out, the common signal configuration is switched from the second common signal configuration to the first common signal configuration.

[0112] In one implementation, the timer is associated with a common signal change period in the common signal configuration.

[0113] Exemplarily, when the common signal configuration takes effect, a timer is started. When the timer times out, the first node detects a common signal configuration change indication and determines whether to update the common signal configuration based on the common signal change period indicated by the common signal configuration change indication.

[0114] In another exemplary embodiment, the timer may be associated with at least one of the following: a cell DTX (Discontinuous Transmission) / DRX on-duration timer and a connected DRX (C-DRX) on-duration timer. For example, a first common signal configuration is used during the operation of the cell DTX / DRX on-duration timer or the C-DRX on-duration timer, and a second common signal configuration is used when the cell DTX / DRX on-duration timer or the C-DRX on-duration timer times out.

[0115] In this way, by associating the timer with the common signal configuration, the update of the common signal configuration is indicated by the timer, which can improve the flexibility and efficiency of the update without external triggering of the update.

[0116] In some embodiments, the common signal configuration is determined by the terminal type.

[0117] For example, for terminals running wireless communication technology version 19 (R19) or earlier, the common signal configuration is a default common signal configuration or is configured by RRC signaling. For example, for terminals running R19 or later, the common signal configuration may be configured by at least one of the following: RRC signaling, SIB1, L1 signaling, L2 signaling, or a timer.

[0118] In some embodiments, the common signal configuration is determined by terminal capabilities.

[0119] For example, for a terminal that does not support the base station energy-saving terminal capability, the common signal configuration is a default common signal configuration or is configured by RRC signaling. For a terminal that supports the base station energy-saving terminal capability, the common signal configuration may be configured by at least one of the following: RRC signaling, SIB1, L1 signaling, L2 signaling, or a timer.

[0120] In this way, determining the common signal configuration based on the terminal type or terminal capability can provide more flexible configuration options. In addition, determining the common signal configuration based on the terminal type or terminal capability can improve the matching degree between the common signal configuration and the terminal, thereby improving the compatibility and applicability of the common signal configuration.

[0121] S102: Detect a common signal or transmit a common signal based on the common signal configuration.

[0122] The common signal configuration includes at least one of the following: common signal transmission period, common signal transmission period scaling factor, common signal repetition period, common signal modification period, common signal subcarrier spacing, common signal pattern, common signal index indication, common signal transmission power, common signal power offset, common signal time domain offset, and common signal configuration timer.

[0123] Exemplarily, the common signal change period may be predefined. For example, the common signal change period may be configured by RRC signaling or SIB (eg, SIB1).

[0124] In another exemplary embodiment, the common signal change period is the validity period of the common signal configuration. Alternatively, the common signal change period is the basic unit of the validity period of the common signal configuration. For example, the validity period of the common signal configuration is equal to N times the common signal change period. The common signal change period is equal to N times the system information modification period (SI modification period). The common signal change period is equal to N times the discontinuous reception (DRX) period. The common signal change period is equal to N times the extended discontinuous reception (e-DRX) period. The common signal change period is equal to N times the TRS validity duration. N is a positive integer.

[0125] Thus, the diversity of public signal configurations can adapt to more network conditions and improve the flexibility of public signal configurations. In addition, the detailed design of public signal configurations can improve the accuracy of public signal configurations.

[0126] In some embodiments, the validity period of the common signal configuration is associated with at least one of the following: an application period associated with the common signal configuration, a timer associated with the common signal configuration, a common signal change period, or a predefined time.

[0127] For example, when the validity period of the common signal configuration is associated with the application period associated with the common signal configuration, the validity period of the common signal configuration may be equal to M times the application period associated with the common signal configuration. Alternatively, when the validity period of the common signal configuration is associated with a timer associated with the common signal configuration, if the timer associated with the common signal configuration times out, the common signal configuration becomes invalid. Alternatively, when the validity period of the common signal configuration is associated with the common signal change period, the validity period of the common signal configuration may be equal to N times the common signal change period. Both N and M are positive integers.

[0128] As another example, when the validity period of the common signal configuration is associated with a predefined time, the validity period of the common signal configuration may be configured by RRC signaling or by SIB1. Alternatively, the validity period of the common signal configuration may be equal to N times the system information modification period. Alternatively, the validity period of the common signal configuration may be equal to N times the default paging cycle. Alternatively, the validity period of the common signal configuration may be equal to N times the TRS validity period. N is a positive integer.

[0129] In some embodiments, the effective time of the public signal configuration includes any one of the following: the current moment, the start time of the next application cycle of the current application cycle, the start time of the next public signal change cycle of the current public signal change cycle, and the start time of the second wireless frame.

[0130] The system frame number A of the second radio frame satisfies the following relationship:

[0131] (A+B) mod T = 0;

[0132] B is any one of the following: RF offset of the public signal configuration, predefined parameters, and high-level configuration parameters; T is any one of the following: validity period of the public signal configuration, application period associated with the public signal configuration, public signal change period, and predefined parameters.

[0133] For example, B may be configured by RRC signaling or SIB. Alternatively, B may be 0. Alternatively, B may be a cell-level parameter. T may also be configured by a higher layer or SIB.

[0134] In other embodiments, the effective time of the common signal configuration may be determined according to the time when the first node receives the first signaling.

[0135] Exemplarily, after the first node receives the first signaling, the common signal configuration takes effect immediately. Alternatively, in some embodiments, the common signal configuration takes effect after a predefined time after receiving the first signaling.

[0136] It should be noted that when the common signal configuration is adopted, a common signal configuration timer is started. When the common signal configuration timer times out, the common signal configuration is switched to a default common signal configuration or a designated common signal configuration.

[0137] In some embodiments, the common signal configuration is used for at least one of the following: a common signal configuration used by a base station to transmit a common signal, a common signal configuration used by a terminal to detect a common signal, a currently used common signal configuration, and an updated common signal configuration.

[0138] In some embodiments, the common signal includes at least one of the following: synchronization signal / physical broadcast channel block SSB, system information block SIB1, physical random access channel PRACH, paging, discovery reference signal (DRS), primary synchronization signal PSS, secondary synchronization signal SSS, channel state information-reference signal (CSI-RS).
