It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0046] In related communication technologies, DSS refers to dynamic spectrum sharing, which allows 4G LTE and 5G NR to share the same spectrum and dynamically allocate time-frequency resources to 4G users and 5G users, thereby making it possible to simultaneously deploy 4G cells and 5G cells in the same frequency band.

[0047] The main advantages of DSS technology include the following a)-c).

[0048] a) Efficient use of spectrum resources: By dynamically allocating spectrum resources, DSS can adjust the spectrum usage of 4G and 5G according to real-time needs, thereby improving spectrum utilization.

[0049] b) Smooth transition: Operators can gradually introduce 5G services without affecting existing 4G services, reducing the cost and complexity of spectrum reconstruction.

[0050] c) Enhanced network performance: DSS can provide 5G services on existing frequency bands, improving network coverage and capacity.

[0051] It is found through research that in the 4G / 5G DSS, the two wireless access technologies of LTE and NR work independently, that is, the coexistence of LTE and NR can be understood as a coexistence with low system coupling degree, thereby leading to problems such as large signaling overhead in cell camping, cell measurement and other processes of cells under different wireless access technologies when deploying cells supporting different wireless access technologies in the same frequency band based on the DSS scheme.

[0052] To this end, taking 5G wireless access technology (5G or 5G NR or NR, etc. for short) and 6G wireless access technology (6G for short) as an example, it is considered in the present application that in the process of evolution from 5G NR to 6G wireless access technology, the design of physical layer signals can be reused to some extent. For example, since the physical layer signal design of NR is relatively flexible, the physical layer signal of 6G can directly reuse the physical layer signal of NR. For another example, 6G may need to design new physical layer signals for new application scenarios (such as Wireless Sensing), including measurement signals based on frequency-modulated continuous wave (FMCW) waveform, but at the same time, it can also reuse the NR physical layer signal for data transmission, so that the NR physical layer signal set is integrated into a subset of the physical layer signal set supported by the 6G system. If 6G follows part or all of the NR physical layer signal design, the coexistence of 5G NR system and 6G system will be a coexistence with high system coupling degree. Based on this, the present application provides a communication scheme, which can realize signal reuse under different wireless access technologies and solve the problem of large signaling overhead in cell camping, cell measurement and other processes of cells under different wireless access technologies. Different wireless access technologies can include but are not limited to 4G wireless access technology, 5G, 6G or other future wireless access technologies, etc.

[0053] It should be noted that the terms "reuse", "share", "reuse", "support reuse" mentioned in the context of the present application have the same meaning, indicating that the first object can use the same signal, resource as the second object to perform a certain function, action. For example, the second cell reuses the synchronization signal of the first cell, which means that the second cell can use the synchronization signal of the first cell to enable synchronization function (of the terminal) and the like.

[0054] Based on this, the technical solutions provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and their application scenarios.

[0055] As shown in FIG. 2, a flowchart of a communication method 200 provided by an exemplary embodiment of the present application is shown, which can be executed by a terminal, but is not limited to this. In this embodiment, the method 200 can at least include the following steps.

[0056] S210, the terminal acquires a first signal of a first cell.

[0057] S220, the terminal performs a target operation according to the first signal, the target operation including at least one of operations 1-3.

[0058] Operation 1: Acquire a second signal.

[0059] The second signal is used for the terminal to camp on the second cell or for the terminal to perform a service corresponding to the second cell or to perform a measurement of the second cell, and the first cell and the second cell correspond to different wireless access technologies, such as the first cell corresponding to 5G (or 6G) and the second cell corresponding to 6G (or 5G).

[0060] That is, in the related art, when performing DSS, the first signal needs to be sent by the second cell to acquire the second signal, and the camping of the second cell or the measurement of the second cell or the execution of the service corresponding to the second cell is performed. In this embodiment, the second signal can be acquired by multiplexing the first signal of the first cell to perform the camping of the second cell or the service corresponding to the second cell, so that when the camping or measurement of the second cell is performed or the service corresponding to the second cell on the terminal is enabled, the transmission of the second signal required is reduced, the signaling overhead is reduced, the network energy is saved, the system throughput is increased, and DSS with a certain coupling degree between different wireless access technology systems is realized.

[0061] Optionally, when camping on the second cell or performing the service corresponding to the second cell, the terminal can be implemented only according to the second signal, or can be implemented according to the first signal and the second signal, which is not limited herein.

[0062] It should be noted that the "service corresponding to the second cell" mentioned in the context of the present application can be understood as the service or characteristics of the wireless access technology corresponding to the second cell, or the wireless access technology service or wireless access technology characteristics corresponding to the second cell, etc. For example, when the wireless access technology corresponding to the second cell is 6G, the service corresponding to the second cell can include but is not limited to 6G wireless sensing (Sensing) service, network energy saving (NES), non-terrestrial network (NTN), limited capability (RedCap) terminal, artificial intelligence (AI) related enhanced characteristics, etc.

[0063] The measurement of the second cell mentioned in the context of the present application can include, but is not limited to, cell measurement when performing cell reselection or selection, cell measurement involved when performing services corresponding to the second cell, etc., without limitation.

[0064] In addition, in addition to the aforementioned first cell and second cell being 5G cells or 6G cells, in the present embodiment, the first cell or the second cell can also be 4G cells or 3G cells or cells corresponding to other future mobile communication technologies, etc., without limitation.

[0065] Operation 2: Perform measurement of the second cell. Wherein the wireless access technology corresponding to the first cell and the second cell is different, such as the first cell corresponding to 5G (or 6G) and the second cell corresponding to 6G (or 5G), etc.

[0066] That is, compared with the case in the related art that the terminal needs to perform measurement of the second cell based on the signal transmitted by the second cell, in the present embodiment, the measurement of the second cell can be implemented by multiplexing the first signal of the first cell, so that when performing measurement of the second cell, the transmission of the required signal of the second cell is reduced, the signaling overhead is effectively reduced, the network energy is saved, and DSS with a certain coupling degree between different wireless access technology systems is achieved.

[0067] Exemplarily, assuming in a multi-resolution spectrum sensing (MRSS) scenario, compared with the case in the related art that the reselection evaluation of the second cell needs to be performed based on intra-frequency cell reselection and inter-frequency cell reselection, in the present embodiment, considering that in the spectrum sharing scenario, since the first cell and the second cell use the same or overlapping spectrum resources, cell measurement can be further implemented in a signal sharing manner, such as the first cell and the second cell multiplexing the same first signal, then the measurement evaluation required by the terminal when performing cell selection or reselection of the second cell can be performed based on the first signal of the first cell, so that when performing measurement of the second cell, the transmission of the required signal of the second cell is reduced, the signaling overhead is reduced, and the network energy is saved.

[0068] Operation 3: Wake up the second cell.

[0069] That is, compared with the case that the terminal needs to receive the signal sent by the second cell to wake up the second cell in the related art, the terminal can wake up the second cell by multiplexing the first signal of the first cell in the embodiment, so that the signaling overhead is effectively reduced, the network energy is saved, and the DSS with a certain coupling degree between different radio access technology systems is realized when the terminal wakes up the second cell.

[0070] In the embodiment, the terminal acquires the first signal of the first cell, acquires the second signal according to the first signal, performs measurement on the second cell, or wakes up the second cell, wherein the second signal is used for the terminal to camp on the second cell or perform a service corresponding to the second cell or perform measurement on the second cell, so that the signaling overhead is effectively reduced, the network energy is saved, and the system throughput is increased when the terminal camps on the second cell or performs measurement on the second cell or wakes up the second cell or enables the service corresponding to the second cell on the terminal by multiplexing the signal of the first cell, and the DSS with a certain coupling degree between different radio access technology systems is realized.

[0071] Based on this, for the operation 1 in the foregoing S220, that is, the case that the terminal acquires the second signal according to the first signal, the acquisition manner of the second signal provided in the embodiment can include but is not limited to at least one of the following manner 11 to manner 13.

[0072] Manner 11: The terminal acquires the second signal from the first cell.

[0073] In the manner 11, for the case that the terminal needs to camp on the second cell, the terminal can acquire the second signal from the first cell by multiplexing the first signal of the first cell to realize camping on the second cell, that is, the manner of multiplexing the first signal and the second signal of the first cell by the second cell in the manner 11 can reduce the transmission of the signal of the second cell when the terminal camps on the second cell, thereby avoiding the problem of large signaling overhead caused by the need for the second cell to send the first signal and the second signal for cell camping in the related art, saving the network energy, and increasing the system throughput.

[0074] For the case of performing the service corresponding to the second cell or performing the measurement of the second cell, in the case that the terminal supports the service corresponding to the second cell, no matter whether the terminal camps on the second cell or not, or whether the terminal is in a radio resource control (RRC) connected state in the second cell or not, the terminal can acquire the second signal of the first cell by multiplexing the first signal of the first cell, and then perform (or enable) the service corresponding to the second cell or perform the measurement of the second cell by using the second signal. That is, in the mode 11, the second cell can perform the service corresponding to the second cell or perform the measurement of the second cell by sharing the first signal and the second signal of the first cell, so that when the service corresponding to the second cell or the measurement of the second cell on the terminal is enabled or performed, the transmission of the second signal of the second cell required is reduced, the problem that the terminal needs to camp on the second cell or be in an RRC connected state in the prior art to perform the service corresponding to the second cell is avoided, the problem that the second cell needs to transmit the second signal for service performance and causes large signaling overhead is also avoided, the network energy is saved, and the system throughput is increased.

[0075] Mode 12: The terminal acquires the second signal from the second cell.

[0076] In the mode 12, the terminal acquires the second signal from the second cell by multiplexing the first signal of the first cell, so as to realize the camping of the second cell or perform the service corresponding to the second cell or perform the measurement of the second cell. That is, in the mode 12, the second cell can multiplex the first signal of the first cell, so that when the camping of the second cell or the service corresponding to the second cell or the measurement of the second cell on the terminal is enabled or performed, the transmission of the second signal of the second cell required is reduced, the problem that the second cell needs to transmit the second signal for cell camping or service performance and causes large signaling overhead is avoided, the network energy is saved, and the system throughput is increased.

[0077] Mode 13: The terminal acquires the second signal from a third cell, wherein the third cell is indicated by the first cell and has the same radio access technology as the first cell.

[0078] In the mode 13, for the case that the terminal needs to camp on the second cell, the terminal can acquire the second signal from the third cell by multiplexing the first signal of the first cell, so as to camp on the second cell. That is, in the mode 13, the second cell can multiplex the first signal of the first cell and the second signal of the third cell, so that when the terminal camps on the second cell, the transmission of the second signal of the second cell can be reduced, the problem of large signaling overhead caused by the second cell transmitting the first signal and the second signal for cell camping in the prior art can be avoided, the network energy can be saved, and the system throughput can be increased.

[0079] For the case of performing the service corresponding to the second cell or performing the measurement of the second cell, when the terminal supports the service corresponding to the second cell or the measurement of the second cell, the terminal can acquire the second signal of the third cell by multiplexing the first signal of the first cell, and then perform the service corresponding to the second cell or the measurement of the second cell by using the second signal. That is, in the mode 13, the second cell can multiplex the first signal of the first cell and the second signal of the third cell, so as to perform the service corresponding to the second cell or the measurement of the second cell, which can reduce the transmission of the second signal of the second cell when the terminal performs the service corresponding to the second cell or the measurement of the second cell, avoid the problem that the terminal needs to camp on the second cell or be in the RRC connected state to perform the service corresponding to the second cell in the prior art, avoid the problem of large signaling overhead caused by the second cell transmitting the second signal, save the network energy, and increase the system throughput.

[0080] It is worth noting that the third cell and the first cell can correspond to the same network side device. For example, in the embodiment, the first cell can be a serving cell of the terminal, and the third cell can be an energy saving cell indicated by the serving cell.

[0081] In addition, the network side device can be a base station or a TRP in a physical sense, or a cell in a logical sense, which is not limited herein.

[0082] In some embodiments, for the aforementioned case of acquiring the second signal according to the first signal, the terminal can acquire the second signal in the aforementioned manner 11-13, which can include but is not limited to: the terminal can first acquire target multiplexing pattern or signal resource configuration information, and then acquire the second signal from the second cell according to the target multiplexing pattern or signal resource configuration information. The target multiplexing pattern is the multiplexing pattern between the first signal and the second signal, and the signal resource configuration information is used to indicate the transmission resource of the second signal transmission.

[0083] That is, after receiving the first signal, the terminal can acquire the second signal according to the multiplexing pattern between the first signal and the second signal, or according to the signal resource configuration information corresponding to the second signal. In this way, the efficiency of acquiring the second signal and the reliability of the acquisition result can be improved.

[0084] It can be understood that the target multiplexing pattern can be understood as a way of implicitly indicating the transmission resource of the second signal transmission, and the signal resource configuration information can be understood as a way of explicitly indicating the transmission resource of the second signal transmission. In this embodiment, the transmission resource of the second signal transmission can include but is not limited to time domain resource, frequency domain resource, signal period, signal pattern, etc.

[0085] Optionally, the target multiplexing pattern and the signal resource configuration information can be acquired in the following ways, which can include but are not limited to: protocol agreement, configuration by the first cell, etc. For example, for the configuration by the first cell, the target multiplexing pattern and / or the signal resource configuration information can be indicated by first indication information carried in the first signal. Optionally, the first signal can be but is not limited to RRC signaling, system message, medium access control control element (MAC CE) signaling, etc.

[0086] In addition, in some embodiments, the first indication information carried in the first signal can also be used to indicate whether the second signal exists. In this way, the terminal acquires the second signal according to the first indication information, avoiding the invalid acquisition behavior that can occur when the terminal does not know whether the second signal exists and acquires the second signal, and further avoiding the problems of signaling overhead, resource waste, etc. caused by invalid acquisition behavior. For example, when the first indication information indicates that the second signal does not exist, the terminal still initiates an acquisition request for the second signal according to the first signal, resulting in invalid acquisition behavior.

[0087] Optionally, the first indication information can be carried by a reserved bit or a newly added bit in the first signal, which is not limited herein. For example, when the reserved bit or the newly added bit is 1, it means that the second signal exists, otherwise, it means that the second signal does not exist.

[0088] As an optional implementation, the first signal or the second signal mentioned in the foregoing implementations can include but is not limited to at least one of a synchronization signal, a synchronization signal block (SSB), a physical broadcast channel (PBCH), a master information block (MIB), a system message, control signaling, a tracking reference signal (TRS), a positioning reference signal (PRS), a demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS).

[0089] The synchronization signal can include but is not limited to at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). For example, in the present application, the synchronization signal can also be other reference signals that can be used for synchronization, such as a new synchronization signal designed in a future communication system (such as 6G / 7G) and the like.

[0090] The system message can be but is not limited to a system information block (SIB) 1 or other system information (OSI), and the like.

[0091] The control signaling can be but is not limited to RRC signaling, MAC CE signaling, and the like, which is not limited herein.

[0092] Based on this, in an optional implementation, the first signal and the second signal can satisfy but are not limited to at least one of the following 11)-16).

[0093] 11) the first signal is PSS, and the second signal comprises at least one of SSS, SSB, PBCH, MIB.

[0094] 12) the first signal is SSS, and the second signal comprises at least one of PSS, SSB, PBCH, MIB.

[0095] 13) the first signal is PSS and SSS, and the second signal comprises at least one of SSB, PBCH, MIB.

[0096] 14) the first signal is SSB, and the second signal comprises at least one of SSB, PBCH, MIB, SIB.

[0097] 15) the first signal comprises system message or control signaling, and the second signal comprises at least one of SSB, PBCH, MIB, system message.

[0098] 16) the first signal is first DMRS, and the second signal is second DMRS, wherein the first DMRS and the second DMRS are located in different time units. The time unit can be symbol, slot, subframe, etc., which is not limited herein.

[0099] In some embodiments, in the case that the first signal is the synchronization signal (such as PSS or SSS, etc.) or SSB, and the second signal comprises the PBCH, the PBCH in the first signal and the PBCH in the second signal are located in different time domain resources or frequency domain resources, thereby avoiding the problem of transmission resource conflict, etc. The second signal can be PBCH, or a synchronization signal, SSB, MIB, etc. comprising PBCH.

[0100] In some embodiments, in the case that the first signal and the second signal are both the PBCH, the MIB or the system message, the information carried in the second signal is different from the information carried in the first signal, or the information carried in the second signal does not include the information already carried in the first signal. That is, relative to the information carried in the first signal, the second signal can carry additional information, such as additional SIB1, additional OSI, etc. Thus, the problem of resource waste caused by repeated transmission can be avoided.

[0101] In some embodiments, the terminal obtaining the second signal according to the first signal in S210 can include but is not limited to: in a case where the first signal carries target configuration information, the terminal obtaining the second signal according to the target configuration information. The target configuration information is used to indicate request configuration information for the terminal to request to obtain the second signal, and the target configuration information corresponds to the first cell, the second cell, or the third cell.

[0102] In this embodiment, the second signal can include but is not limited to an on-demand signal such as an on-demand (OD)-SSB, an NES OD-SIB1, a 6G OD-PBCH, etc. Correspondingly, the target configuration information can also be referred to as on-demand signal request configuration information corresponding to the first cell or the second cell or the third cell, which is used to request the second signal such as the on-demand signal, and then perform cell camping of the second cell, perform (or enable) service corresponding to the second cell, or perform measurement of the second cell, etc. based on the requested second signal.

[0103] Based on this, as an optional implementation, for a case where the target configuration information corresponds to the first cell or the third cell, the terminal obtaining the second signal according to the target configuration information can include but is not limited to: in a case where the terminal determines that the target configuration information corresponds to a target cell (such as the first cell or the third cell), and a second signal corresponding to the target cell can be used for cell camping of the second cell or service corresponding to the second cell, the terminal requests the network side device corresponding to the target cell to obtain the second signal according to the target configuration information.

[0104] That is, in this implementation, the terminal does not need to know whether the first cell or the third cell supports the second cell or service corresponding to the second cell, but only needs to determine whether to request the second cell or the third cell for the second signal according to whether the second signal can be used for cell camping of the second cell or service corresponding to the second cell or measurement of the second cell. For example, if the second signal can be used for cell camping of the second cell or service corresponding to the second cell or measurement of the second cell, the terminal can request the first cell or the third cell for the second signal.

[0105] Based on this, as an optional implementation, for a case where the target configuration information corresponds to the first cell or the third cell, the target configuration information can also be referred to as on-demand signal request configuration information corresponding to the first cell or the third cell, which is used for the terminal to request the first cell or the third cell for the second signal.

[0106] Optionally, the target configuration information corresponding to the first cell or the third cell can include, but is not limited to, at least one of 21) to 24).

[0107] 21) Type of the second signal, such as SSB, TRS, PRS, DMRS, etc.

[0108] 22) Resource configuration of the second signal, such as time domain resource, frequency domain resource, signal period, signal pattern, etc.

[0109] 23) Resource configuration for requesting the second signal, such as message 1 (Msg1) related configuration information (or called preamble configuration information) or Msg3 related configuration information of a random access procedure; the Msg1 / Msg3 is used to request an on-demand signal of the first network side device.

[0110] 24) Identifier of the first network side device. Wherein, the first network side device corresponds to the target cell, such as a network side device corresponding to the first cell and / or the third cell. Wherein, the network side devices corresponding to the first cell and the third cell can be the same or different.

[0111] Optionally, the identifier of the first network side device can include, but is not limited to, physical cell identifier (PCI), cell ID, gNB-ID, etc.

[0112] Optionally, the terminal can determine in multiple ways whether the second signal corresponding to the target cell (such as the first cell or the third cell) can be used for camping on the second cell or the service corresponding to the second cell or the measurement of the second cell.

[0113] In an implementation manner, the terminal can determine, according to the type of the second signal included in the target configuration information and the terminal capability, whether the second signal corresponding to the target cell can be used for camping on the second cell or the service corresponding to the second cell or the measurement of the second cell. For example, when the terminal supports multiplexing the second signal (such as 5G PRS) of a 5G cell (i.e., the first cell) to perform the service corresponding to a 6G cell (i.e., the second cell), such as 6G wireless sensing service, and the type of the second signal included in the target configuration information includes PRS, the terminal can initiate an acquisition request of the 5G PRS to the target cell according to the target configuration information, otherwise, the terminal cannot initiate the acquisition request of the second signal.

[0114] In another implementation, in the case that the first signal further includes second indication information, the terminal can determine, according to the second indication information, that the second signal corresponding to the target cell can be used for camping of the second cell or a service corresponding to the second cell or measurement of the second cell; wherein the second indication information is used to indicate that the second cell or the service corresponding to the second cell supports multiplexing of the second signal corresponding to the target cell (such as a first cell or a third cell), such as wireless sensing, AI+X (AI assisted X, AI enhanced X), and the like.

[0115] For example, when the terminal is preparing to perform a 6G wireless sensing feature application, and the second indication information indicates that 6G wireless sensing features support multiplexing of the second signal of the target cell, the terminal can initiate a request for acquisition of the second signal according to the target configuration information.

[0116] Optionally, the second indication information can carry, but is not limited to, the target configuration information.

[0117] In addition, in addition to being able to determine that the second signal corresponding to the target cell can be used for camping of the second cell or a service corresponding to the second cell or measurement of the second cell through the foregoing manner, the terminal can also be configured with information related to whether the second signal corresponding to the target cell can be used for camping of the second cell or a service corresponding to the second cell or measurement of the second cell through protocol agreement or the like, which is not limited herein.

[0118] In addition to the foregoing case that the target configuration information corresponds to the first cell or the third cell, for the case that the target configuration information corresponds to the second cell, the process of the terminal acquiring the second signal according to the target configuration information can include but is not limited to: in the case of determining that the target configuration information corresponds to the second cell, the terminal requests a network side device corresponding to the second cell to acquire the second signal according to the target configuration information for camping of the terminal in the second cell or performing a service corresponding to the second cell or performing measurement of the second cell, and the like.

[0119] Optionally, the target configuration information corresponding to the second cell can include but is not limited to at least one of the following 31)-34).

[0120] 31) signal configuration information, used to indicate related configurations of the second signal of the second cell.

[0121] Optionally, the signal configuration information includes but is not limited to at least one of 31a)-31d).

[0122] 31a) Type of the second signal, such as SSB, MIB (or PBCH), SIB, TRS, PRS, DMRS, etc.

[0123] 31b) Resource configuration of the second signal, such as time domain resource, frequency domain resource, signal periodicity, signal pattern, etc.

[0124] 31c) Resource configuration for requesting the second signal, such as Msg1 related configuration information (or called preamble configuration information), Msg3 related configuration information; the Msg1 / Msg3 is used for requesting on-demand signal of the second cell or the network side device corresponding to the first cell.

[0125] 31d) Identification of the second network side device. Wherein, the second network side device is the network side device corresponding to the second cell or the first cell. Optionally, the identification of the second network side device can include but is not limited to PCI, cell ID, gNB-ID, etc.

[0126] 32) Third indication information, used for indicating the service supported by the second cell, such as wireless sensing service, network energy saving, non-ground network, limited capability terminal, AI related enhanced feature, etc.

[0127] 33) Fourth indication information, used for indicating that the second cell or the service corresponding to the second cell supports the signal (such as the first signal, the second signal, etc. of the first cell) of the first cell in multiplexing.

[0128] Wherein, for "the second cell supports the signal of the first cell in multiplexing", it can be understood that one or more processes in the second cell support the signal of the first cell in multiplexing, such as one or more of cell measurement, cell camping, enabling of the service corresponding to the cell, etc. in the second cell.

[0129] For "the second cell supports the signal of the first cell in multiplexing", it can be understood that: the second cell supports the signal of the first cell in multiplexing, and / or the second cell supports the signal configuration information (such as resource configuration information, signal type, etc.) of the signal of the first cell in multiplexing. Wherein, the resource configuration can include but is not limited to time domain resource, frequency domain resource, signal periodicity, etc., and the signal type includes SSB, TRS, PRS, DMRS, etc.

[0130] For example, assuming that the service corresponding to the second cell includes wireless sensing feature or artificial intelligence related enhanced feature, then the fourth indication information can indicate that the measurement signal of the wireless sensing feature or artificial intelligence related enhanced feature supports to multiplex the SSB, PRS, etc. of the first cell.

[0131] 34) a fifth indication information, used for indicating a signal of the first cell or a service corresponding to the second cell being multiplexed by the first cell, such as a first signal, a second signal.

[0132] wherein, for the signal of the first cell being multiplexed by the second cell, it can be understood as the signal of the first cell being multiplexed by one or more procedures in the second cell, such as one or more of cell measurement, cell camping, enabling of the service corresponding to the cell in the second cell, etc.

[0133] For the signal of the first cell being multiplexed by the second cell, it can be understood as: the signal of the first cell being multiplexed by the second cell, and / or, the signal configuration information of the signal of the first cell being multiplexed by the second cell, such as resource configuration information, signal type, etc. Wherein, the resource configuration can include but is not limited to time domain resource, frequency domain resource, signal period, etc., and the signal type includes SSB, TRS, PRS, DMRS, etc.

[0134] For example, assuming that the second cell is multiplexing the functions of enabling the terminal's radio resource management (RRM) measurement, synchronization, etc. of the SSB of the first cell, when the terminal wants to camp on the second cell, it only needs to request the MIB or SIB1 message of the second cell, without the need to request the synchronization signal or synchronization signal block, etc. of the second cell.

[0135] It should be noted that if the target configuration information does not exist, when the terminal considers or assumes the signal necessary for requesting to camp on the second cell, it needs to request the complete synchronization signal or synchronization signal block, etc. of the second cell.

[0136] In some embodiments, for the case that the target configuration information corresponds to the second cell, the process of the terminal requesting to obtain the second signal from the network side device corresponding to the second cell according to the target configuration information can include but is not limited to: the terminal determines to meet the first condition, and requests to obtain the second signal from the network side device corresponding to the second cell according to the target configuration information. Thus, it is ensured that the terminal requests the second signal that meets the needs.

[0137] Wherein, the first condition can include but is not limited to at least one of the following conditions 1-5.

[0138] Condition 1: The terminal supports the second cell multiplexing the first signal (such as the first signal, the second signal) of the first cell to camp on the second cell or perform the service corresponding to the second cell or perform the measurement of the second cell, etc. That is, the terminal can determine the second signal that needs to be requested according to the terminal capability supporting the multiplexed signal.

[0139] For example, assuming that the first cell is a 5G cell, the second cell is a 6G cell, and a terminal needs to request the synchronization signal or system information of the second cell to complete the camping of the second cell. Then, if the terminal (capability) supports multiplexing the SSB of the 5G cell for time-frequency synchronization or ACG, the terminal can request the MIB and SIB1 of the 6G cell, i.e., the second signal, according to the target configuration information as needed to camp on the 6G cell.

[0140] If the terminal (capability) does not support multiplexing the SSB of the 5G cell for time-frequency synchronization or ACG, the terminal needs to request the on-demand SSB (including cell synchronization signal and MIB) and SIB1 of the 6G cell to camp on the 6G cell.

[0141] Exemplarily, a possible design scheme of 5G and 6G SSBs is shown in FIG. 3a, in which the 6G SSB can multiplex the PSS and / or SSS part of the 5G SSB.

[0142] When the 6G cell does not send (periodic) 6G PBCH as shown in FIG. 3b, if the 6G terminal can perform synchronization based on the 5G SSB, the terminal only needs to request the second signal, i.e., the 6G OD-PBCH; if the 6G terminal does not support synchronization based on the 5G SSB, it needs to request the complete 6G SSB (including cell synchronization signal and MIB).

[0143] Condition 2: The terminal supports the second radio access technology multiplexing the first signal of the first radio access technology to camp on the second cell or perform the service corresponding to the second cell or perform the measurement of the second cell, etc. Wherein the second radio access technology is the radio access technology corresponding to the second cell, and the first radio access technology is the radio access technology corresponding to the first cell or the third cell.

[0144] For example, the radio access technology corresponding to the first cell is 5G, and the radio access technology corresponding to the second cell is 6G. Then, the terminal can request the second signal to the first cell or the second cell according to the target configuration information in the case of supporting 6G multiplexing the first signal of 5G, to camp on the second cell, perform the measurement of the second cell, enable the service corresponding to the second cell, etc.

[0145] It is worth mentioning that the aforementioned condition 1 can also be understood as a possible implementation of condition 2, for example, the terminal can further determine that the terminal supports the second cell under the second radio access technology to multiplex the signal of the first cell under the first radio access technology in the case of determining that condition 2 is satisfied.

[0146] Condition 3: The service supported by the second cell indicated by the third indication information includes the service corresponding to the second cell supported by the terminal or the service corresponding to the second cell that needs to be initiated by the terminal.

[0147] For example, when the service corresponding to the second cell indicated by the third indication information contains wireless sensing, the terminal supporting wireless sensing or the terminal preparing to perform wireless sensing service can initiate a request for the second signal (also called on-demand signal) according to the target configuration information to perform cell camping, measurement, and enablement of the second cell.

[0148] Condition 4: The signal of the first cell that is multiplexed by the second cell or the service corresponding to the second cell indicated by the fourth indication information includes the signal of the first radio access technology that is multiplexed by the terminal, such as the signal of the first cell (such as the first signal, the second signal, etc.) that is multiplexed by the terminal.

[0149] For example, when the terminal is preparing to perform a wireless sensing characteristic application, the wireless sensing characteristic application supports the signal of the first cell that is multiplexed, and the fourth indication information indicates that the second cell or the service corresponding to the second cell supports the execution of wireless sensing characteristics for the first signal that is multiplexed, the terminal can initiate a request for the second signal according to the target configuration information to perform cell camping, measurement, and enablement of the second cell.

[0150] Condition 5: The signal of the first cell that is multiplexed by the second cell or the service corresponding to the second cell indicated by the fifth indication information includes the signal of the first radio access technology that is multiplexed by the terminal, such as the signal of the first cell (such as the first signal, the second signal, etc.) that is multiplexed by the terminal.

[0151] In some embodiments, for the aforementioned case of the terminal obtaining the second signal, the terminal can also determine the cell identifier of the second cell according to any one of 41)-43) below. This can be used for association of second cell related configuration information, reception (such as signal decoding or descrambling, etc.) of the signal corresponding to the second cell.

[0152] 41) the first signal, or a correlation function value of the first signal, wherein the first signal comprises at least one of a PBCH, a PSS, and a SSS.

[0153] In the determining the cell identity of the second cell according to the correlation function value of the first signal, the correlation function value of the first signal can be related to other parameters, for example, the other parameters can comprise but are not limited to a PBCH, a DMRS, and the like corresponding to the second cell.

[0154] In the determining the cell identity of the second cell according to the correlation function value of the first signal, the correlation function value of the first signal can be related to other parameters, for example, the other parameters can comprise but are not limited to a PBCH, a DMRS, and the like corresponding to the second cell.

[0155] It is worth noting that the correlation function value of the first signal and the second signal can be understood as being calculated by using a correlation function (such as a linear function) on the first signal, for example, the correlation function value can be obtained by linear calculation and the like of the first signal by using a linear function, which is not limited in the present embodiment.

[0156] 42) the second signal, wherein the second signal comprises a PBCH.

[0157] 43) the first signal and the second signal, or a correlation function value of the first signal and the second signal, wherein the first signal comprises a PSS, and the second signal comprises a SSS, or the first signal comprises a SSS, and the second signal comprises a PSS.

[0158] It is worth noting that the correlation function value of the first signal and the second signal can be understood as being calculated by using a correlation function (such as a linear function) on the first signal and the second signal, for example, the correlation function value can be obtained by linear calculation and the like of the first signal and the second signal by using a linear function, which is not limited in the present embodiment.

[0159] Optionally, the cell identity of the second cell is used for decoding (or descrambling) of the second signal, wherein the second signal comprises a PBCH. For example, in the case that the scrambling of the second signal is related to the identity of the second cell, the identity of the second cell can be used for decoding of the second signal.

[0160] In some embodiments, for the operation 2 in the foregoing S220, that is, the implementation manner of the terminal performing measurement of the second cell according to the first signal of the first cell, it can comprise but is not limited to any one of the following mode 21 to mode 22.

[0161] Mode 21: the terminal measures target information of the second cell according to the first signal.

[0162] The target information includes at least one of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indication (RSSI), a signal-to-noise and interference ratio (SINR), a system frame number (SFN), an SFN time difference, a reference signal time difference, a frame time difference, a channel occupancy ratio, a channel busy ratio, a transmission-reception time difference, a carrier phase, or a downlink time offset.

[0163] Correspondingly, the first signal can include, but is not limited to, at least one of a PSS, an SSS, an SS, a DMRS, a channel state information reference signal (CSI-RS), a TRS, or a PRS.

[0164] That is, when the terminal needs to perform measurement on the second cell, and the signal transmitted by the first cell is a synchronization signal, an SSS, a PSS, a DMRS, a CSI-RS, a TRS, a PRS, or the like, the terminal can perform measurement based on the aforementioned signal transmitted by the first cell to obtain a measurement quantity, such as an RSRP, an RSRQ, an RSSI, an SINR, an SFN, an SFN time difference, a reference signal time difference, a frame time difference, a channel occupancy ratio, a channel busy ratio, a transmission-reception time difference, a carrier phase, or a downlink time offset, thereby enabling the measurement on the second cell to be performed while reducing the transmission of the signal of the second cell required.

[0165] In some embodiments, the network-side device can instruct the terminal which measurement of the second cell can be multiplexed with which type or category of signal of the first cell.

[0166] Option 22: The terminal measures target information of the second cell according to the first signal and the second signal.

[0167] In the mode 22, the implementation manners of the mode 22 are similar to the mode 21, but different from the mode 21 is that, in the mode 22, when performing the measurement of the second cell, in addition to the first signal, the second signal can also be integrated for measurement. For example, in a measurement process of the second cell, part of the measurement quantity can be measured based on the first signal, and another part of the measurement quantity can be measured based on the second signal.

[0168] For another example, the terminal can first reuse the first signal to camp on the second cell, and then perform the measurement of the second cell based on the second signal of the second cell.

[0169] It is worth noting that the first signal and the second signal in the mode 21 and the mode 22 can refer to the related description in the foregoing description, and will not be described here. For example, the second signal can be obtained according to the foregoing target multiplexing pattern or target configuration information.

[0170] In some embodiments, the terminal sends terminal capability information to the network side device corresponding to the first cell or the third cell, so that the network side device corresponding to the first cell or the second cell can clearly know the capability of the terminal, and then the related information (such as target configuration information, second signal, etc.) configured or sent for the terminal can be matched with the terminal capability.

[0171] The terminal capability information is used to indicate at least one of 51) to 53).

[0172] 51) The terminal supports that the second cell reuses the signal of the first cell or the third cell. For example, the first signal and the second signal of the first cell, and the second signal of the third cell.

[0173] 52) The terminal supports that the second radio access technology reuses the first signal of the first radio access technology, wherein the second radio access technology is the radio access technology corresponding to the second cell, and the first radio access technology is the radio access technology corresponding to the first cell or the third cell.

[0174] It is worth noting that the foregoing 51) can also be understood as a possible implementation manner of 52). For example, if the terminal supports that the second radio access technology reuses the first signal of the first radio access technology as described in 52), it can be determined that the terminal supports that the second cell corresponding to the second radio access technology reuses the first signal of the first cell corresponding to the first radio access technology.

[0175] 53) The service corresponding to the second cell supported by the terminal.

[0176] In some embodiments, the network-side device corresponding to the first cell or the second cell can further send sixth indication information to the terminal, to indicate whether the terminal supports multiplexing the first signal of the first cell, such as whether it supports multiplexing the first signal of the first cell to obtain a second signal, or whether it supports multiplexing the first signal of the first cell for measurement of the second cell, etc. Thus, it is ensured that the terminal and the network-side device have consistent understanding of the first signal.

[0177] In this case, if the terminal receives the sixth indication information, and the sixth indication information indicates that the second cell supports multiplexing the first signal of the first cell, then the terminal can obtain a second signal according to the first signal, or perform measurement of the second cell according to the first signal.

[0178] In the foregoing communication scheme provided by the present application, by multiplexing the signal of the first cell by the second cell, the signal that the second cell needs to send to enable the terminal to perform second cell camping or measurement or to execute the application corresponding to the second cell can be reduced, thereby reducing signaling overhead, obtaining network energy saving, and increasing system available resources / throughput gain.

[0179] Based on the foregoing description of the communication method, for the convenience of understanding, the communication method provided by the embodiments of the present application is exemplarily described as follows.

[0180] Example 1: The second cell multiplexes the first signal of the first cell to realize cell camping

[0181] Assuming that the first cell is a 5G cell, the second cell is a 6G cell, and the 6G cell can multiplex the first signal of the 5G cell, such as the PSS or SSS of the SSB, then only the 6G cell needs to send a second signal, such as a 6G PBCH or a 6G SIB1, to enable the terminal to camp on the 6G cell, thereby reducing the signal that the second cell needs to send to enable the terminal to camp on the second cell, thereby reducing signaling overhead, obtaining network energy saving, and increasing system available resources / throughput gain.

[0182] As shown in FIG. 3a, if a target multiplexing pattern is configured by network-side configuration or protocol agreement, after detecting the 5G SSB, the terminal can detect the 6G PBCH according to the target multiplexing pattern and the 5G SSB, and then the terminal can obtain the 6G SIB1 reception configuration based on the detected 6G PBCH to obtain SIB1.

[0183] Optionally, for the case that the target multiplexing pattern is configured by the network side, after receiving the 5G SSB and camping on the 5G cell according to the indication of the 5G SSB, the terminal can obtain the target multiplexing pattern through the configuration information of the 5G cell (such as OSI in addition to SIB, etc.).

[0184] Optionally, as shown in FIG. 3a, the first indication information can be carried in the PBCH of the 5G SSB, for indicating whether the 6G PBCH exists, if it exists, the terminal performs the aforementioned step of detecting the 6G PBCH according to the target multiplexing pattern and the 5G SSB, otherwise, it stops detecting the 6G PBCH.

[0185] Optionally, the first indication information can be carried in the 1-bit reserved bit in the NR PBCH. For example, when the 1-bit reserved bit is set to 1, it represents that the 6G PBCH exists, otherwise, it represents that the 6G PBCH does not exist.

[0186] Optionally, after receiving the 5G SSB and camping on the 5G cell according to the indication of the 5G SSB, the terminal can obtain the 6G PBCH or the 6G SIB1 through the target configuration information of the 5G cell.

[0187] Optionally, the identity of the 6G cell can be determined by at least one of the following a)-d).

[0188] a) The first signal of the 5G cell, such as the PSS or SSS of the SSB, that is, the identity of the 6G cell can reuse the cell ID determined by the PSS or SSS of the 5G cell.

[0189] b) The correlation function value of the first signal of the 5G cell (such as the PSS or SSS of the SSB), that is, the identity of the 6G cell can be based on the function value of the cell ID determined by the PSS or SSS of the 5G cell.

[0190] Optionally, the function value can also be related to other parameters, such as 6G PBCH, DMRS, etc.

[0191] c) NR PBCH or 6G PBCH

[0192] d) PSS of the 5G cell and SSS of the 6G cell, or SSS of the 5G cell and PSS of the 6G cell.

[0193] Wherein, the identity of the 6G cell determined based on the aforementioned a)-d) can be used for decoding the 6G PBCH, such as the scrambling of the 6G PBCH being related to the identity of the 6G cell.

[0194] Similarly, for the case that the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to the aforementioned case that the first cell is a 5G cell and the second cell is a 6G cell, and will not be described here.

[0195] Example 2: The second signal comes from the first cell for the terminal to camp on the second cell, perform the service corresponding to the second cell, measure the second cell, etc.

[0196] Assuming that the first cell is a 5G cell (i.e., a serving cell) and the second cell is a 6G cell, as shown in FIG. 4a, the terminal acquires the second signal as follows.

[0197] S411, the 5G cell (or the network side device corresponding to the first cell) sends a first signal to the terminal.

[0198] The first signal carries target configuration information, and the target configuration information corresponds to the first cell.

[0199] S412, the terminal determines whether the second signal corresponding to the first cell can be used for the terminal to camp on the second cell or perform the service corresponding to the second cell or perform measurement on the second cell. If so, perform S413; otherwise, the acquisition request of the second signal cannot be initiated.

[0200] S413, according to the target configuration information, a signal request message is sent to the 5G cell to request the second signal (also referred to as an on-demand signal).

[0201] S414, the first cell sends a signal request response message to the terminal according to the signal request message.

[0202] Optionally, the signal request response message can include the second signal, or the signal request response message does not include the second signal, but only as a response message to indicate that the request message is sent successfully.

[0203] When the signal request response message does not include the second signal, the first cell can send the second signal to the terminal through S415, which is not limited here.

[0204] S415, the first cell sends the second signal to the terminal according to the signal request message.

[0205] The terminal can camp on the second cell or perform the service corresponding to the second cell or perform measurement on the second cell according to the second signal, etc.

[0206] In this example 2, the terminal can request a second signal from a 5G cell via target configuration information corresponding to the 5G cell in the case of supporting 5G, 6G DSS capability, for the terminal to camp on the second cell or perform services corresponding to the second cell or perform measurement of the second cell. Thus, on the one hand, when enabling 6G application of the terminal or performing 6G cell camping or performing measurement of the 6G cell, the transmission of the required 6G signal can be reduced, the signaling overhead can be reduced, the corresponding network energy saving gain can be obtained, especially when the second signal of the 5G cell is multiplexed to perform services corresponding to the 6G cell or perform measurement of the 6G cell, so that the terminal does not need to open the 6G cell; on the other hand, the terminal does not need to know whether the 5G cell supports 6G corresponding services or whether the 6G cell camping or 6G cell measurement can be performed, and only needs to decide whether to request the second signal from the 5G cell according to whether the second signal can be used for services corresponding to the 6G cell or 6G cell camping or 6G cell measurement, thereby reducing the complexity of obtaining the second signal.

[0207] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to the foregoing example 2, and details are not repeated here to avoid repetition.

[0208] It can be understood that the related steps of this example 2 can refer to the related description in the foregoing method embodiment 200, and details are not repeated here to avoid repetition. In addition, this example 2 can include but is not limited to the foregoing S411-S415, that is, it can include more or fewer steps than the foregoing.

[0209] Example 3: The second signal is from a third cell for the terminal to camp on the second cell, perform services corresponding to the second cell, perform measurement of the second cell, etc.

[0210] Assuming that the first cell is a 5G cell (i.e., a serving cell) and the second cell is a 6G cell, as shown in FIG. 4b, the terminal obtains the second signal as follows.

[0211] S421, the 5G cell (or the network side device corresponding to the first cell) sends a first signal to the terminal.

[0212] The first signal carries target configuration information, and the target configuration information corresponds to the 5G cell (i.e., the third cell).

[0213] S422, the terminal determines whether the second signal corresponding to the third cell can be used for the terminal to camp on the second cell or perform services corresponding to the second cell or perform measurement of the second cell, and if so, S423 is performed; otherwise, the acquisition request of the second signal cannot be initiated.

[0214] S423, sending a signal request message to the 5G cell (i.e., the third cell) according to the target configuration information, for requesting the second signal (may also be referred to as on-demand signal).

[0215] S424, the third cell sends a signal request response message to the terminal according to the signal request message.

[0216] Optionally, the second signal can be included in the signal request response message, or the signal request response message does not include the second signal, but only as a response message to indicate that the request message is sent successfully.

[0217] Wherein, when the signal request response message does not include the second signal, the first cell can send the second signal to the terminal through S425, which is not limited here.

[0218] S425, the third cell sends the second signal to the terminal according to the signal request message.

[0219] Wherein, the terminal can perform the second cell camping or execute the second cell corresponding service or perform the second cell measurement according to the second signal.

[0220] In this example 3, the terminal can request the second signal from the 5G cell (i.e., the third cell) through the target configuration information corresponding to the 5G cell in the case of supporting 5G, 6G DSS capability, for the terminal camping in the second cell or executing the second cell corresponding service or performing the second cell measurement, thereby enabling the terminal to reduce the transmission of the required 6G signal when enabling the 6G application or performing the 6G cell camping or measuring the second cell, reducing the signaling overhead, and achieving corresponding network energy saving gain, especially when the second signal of the 5G cell is multiplexed to execute the 6G cell corresponding service or perform the 6G cell measurement, so that the terminal does not need to open the 6G cell; on the other hand, the terminal does not need to know whether the 5G cell supports the 6G corresponding service or whether it can realize the 6G cell camping or whether it can perform the 6G cell measurement, only needs to decide whether to request the second signal from the 5G cell according to whether the second signal can be used for the 6G cell corresponding service or 6G cell camping, thereby reducing the complexity of obtaining the second signal.

[0221] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to the foregoing example 3, and details are not repeated here to avoid repetition.

[0222] It can be understood that the relevant steps of the present example 3 can refer to the relevant description in the foregoing method embodiment 200, and details are not repeated here to avoid repetition. In addition, the present example 3 can include but is not limited to the foregoing S421-S425, that is, it can include more or fewer steps than the foregoing.

[0223] Example 4: The second signal is from a second cell for the terminal to camp on the second cell, perform a service corresponding to the second cell, measure the second cell, etc.

[0224] Assuming that the first cell is a 5G cell (i.e., a serving cell) and the second cell is a 6G cell, the terminal acquires the second signal as shown in FIG. 4c.

[0225] S431, the 5G cell (or the network side device corresponding to the first cell) sends a first signal to the terminal.

[0226] The first signal carries target configuration information, and the target configuration information corresponds to the 6G cell (i.e., the second cell).

[0227] S432, the terminal determines whether a first condition is met, if yes, S433 is performed; otherwise, the acquisition request of the second signal cannot be initiated.

[0228] The first condition can refer to the relevant description in the foregoing method embodiment 200, and details are not repeated here.

[0229] S433, according to the target configuration information, a signal request message is sent to the 6G cell (i.e., the second cell) to request the second signal (also referred to as an on-demand signal).

[0230] S434, the second cell sends a signal request response message to the terminal according to the signal request message.

[0231] Optionally, the signal request response message can include the second signal, or the signal request response message does not include the second signal, but only as a response message to indicate that the request message is sent successfully.

[0232] When the signal request response message does not include the second signal, the first cell can send the second signal to the terminal through S415, which is not limited here.

[0233] S435, the second cell sends the second signal to the terminal according to the signal request message.

[0234] The terminal can camp on the second cell, perform a service corresponding to the second cell, or measure the second cell, etc. according to the second signal.

[0235] If the second signal is used for the terminal to camp on the 6G cell or perform the service corresponding to the 6G cell, it can be understood that the terminal can reuse the first signal of the 5G cell and combine the second signal of the 6G cell, so that the terminal can camp on the 6G cell, or perform the service corresponding to the 6G cell, or perform the measurement of the second cell, etc.

[0236] For example, if the capability of the terminal supports time-frequency synchronization, automatic gain control (AGC) using 5G SSB, the terminal only needs to request the MIB or SIB1 of the 6G cell from the 6G cell in order to camp on the 6G cell supporting 6G. Otherwise, the terminal needs to request the cell synchronization signal, MIB or SIB1 of the second cell from the 6G cell.

[0237] Optionally, the signal configuration information carried in the target configuration information can include the MIB of the 6G cell. In other words, the terminal only uses the synchronization signal part of the SSB of the 5G cell to complete time-frequency synchronization and AGC.

[0238] Compared with examples 2 and 3 in which only the second signal is sent by the 5G cell to camp on the 6G cell or perform the service corresponding to the 6G cell or perform the measurement of the 6G cell, in this example 4, the 6G cell (or the 6G network side device) that can be woken up or the target configuration information corresponding to the 6G cell can be indicated by the 5G cell to obtain the second signal from the 6G cell, perform the service corresponding to the 6G cell, or camp on the 6G cell or perform the measurement of the 6G cell, etc. Thus, when camping on the second cell or measuring the second cell or enabling the service corresponding to the second cell on the terminal, the transmission of the required signal of the second cell is reduced, the signaling overhead is reduced, and the corresponding network energy saving gain is obtained.

[0239] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to that of the foregoing example 3, and thus is not described again here to avoid repetition.

[0240] It can be understood that the related steps of this example 3 can refer to the related description in the foregoing method embodiment 200, and thus is not described again here to avoid repetition. In addition, this example 3 can include but is not limited to the foregoing S431-S435, that is, it can include more or fewer steps than the foregoing.

[0241] Example 5: The second signal is from the first cell, for the terminal to camp on the second cell, perform the service corresponding to the second cell, measure the second cell, etc.

[0242] Assuming that the first cell is a 5G cell and the second cell is a 6G cell, the terminal acquires the second signal as shown in FIG. 4d according to the following procedure.

[0243] S441, the 5G cell (or the network side device corresponding to the first cell) sends a first signal to the terminal.

[0244] The first signal carries target configuration information corresponding to the 6G cell (i.e., the second cell).

[0245] S442, the terminal determines whether a first condition is met. If yes, S433 is performed; otherwise, the terminal cannot initiate an acquisition request for the second signal.

[0246] The first condition can refer to the related description in the foregoing method embodiment 200, which will not be repeated here.

[0247] S443, a signal request message is sent to the 5G cell (i.e., the first cell) according to the target configuration information, to request the second signal (also referred to as an on-demand signal).

[0248] S454, the first cell sends a signal request response message to the terminal according to the signal request message.

[0249] Optionally, the signal request response message can include the second signal, or the signal request response message does not include the second signal, but only as a response message to indicate that the request message is sent successfully.

[0250] When the signal request response message does not include the second signal, the first cell can send the second signal to the terminal through S415, which is not limited here.

[0251] S445, the first cell sends the second signal to the terminal according to the signal request message.

[0252] The terminal can perform camping on the second cell, or perform services corresponding to the second cell, or perform measurement on the second cell, etc. according to the second signal.

[0253] In Example 5, the terminal requests the second signal from the 5G cell according to the target configuration information corresponding to the 6G cell, to perform the camping or measurement of the 6G cell or perform the service corresponding to the 6G cell, thereby reducing the transmission of the second signal required when camping or measuring the second cell or enabling the service corresponding to the second cell on the terminal, reducing the signaling overhead, and achieving corresponding network energy saving gains.

[0254] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to that of Example 5 described above, and details are omitted here to avoid repetition.

[0255] It can be understood that the related steps of Example 5 can refer to the related description in the foregoing method embodiment 200, and details are omitted here to avoid repetition. In addition, Example 5 can include but is not limited to the foregoing S441-S445, that is, it can include more or fewer steps than the foregoing.

[0256] Example 6: Measurement of the second cell

[0257] Assuming that the first cell is a 5G cell and the second cell is a 6G cell, in the spectrum sharing scenario of the present application, the 5G cell and the 6G cell use the same or overlapping spectrum resources, that is, the 5G cell and the 6G cell further perform the measurement of the 6G cell through signal sharing on the basis of spectrum sharing. For example, the measurement of the 6G cell can be performed according to the first signal of the 5G cell, or the measurement of the 6G cell can be performed according to the first signal of the 5G cell and the second signal of the 5G cell (such as the first cell or the third cell) or the second cell.

[0258] Among them, assuming that the 5G cell and the 6G cell multiplex the same SSS, the terminal can perform the cell selection or reselection RSRP / RSRQ measurement and evaluation of the 6G cell based on the SSS of the 5G cell.

[0259] For example, assuming that the signals transmitted by the 5G cell are PSS, SSS, SSB, DMRS, CSI-RS, TRS, or PRS, the terminal UE can perform the measurement of the 6G cell, such as RSRP, RSRQ, RSSI, SINR, SFN, SFN time difference, reference signal time difference, frame time difference, channel occupancy rate, channel busy rate, transmission-reception time difference, carrier phase, or downlink time offset, based on one or more of the PSS, SSS, SSB, DMRS, CSI-RS, TRS, or PRS transmitted by the 5G cell.

[0260] In this case, considering that the PSS sequence is limited, such as 3, it can cause the PSS-based measurement to be inaccurate, so other signals except the PSS can be used preferentially when performing RSRP or RSRQ measurement of the 6G cell.

[0261] Optionally, in this example 6, the terminal supports multiplexing the signals of the 5G cell for the measurement of the 6G cell.

[0262] Optionally, in this example 6, the network side device can indicate the 6G cell to multiplex the signals of the 5G cell for measurement. For example, the network side device indicates which specific measurement of the 6G cell and which type of signal of the 5G cell is multiplexed for measurement.

[0263] As shown in FIG. 5, a flowchart of a communication method 500 provided by an example embodiment of the present application is shown, which can be executed by the network side device, but is not limited to this.

[0274] In some embodiments, the method further comprises: sending, by the network-side device, sixth indication information to the terminal; wherein the sixth indication information is used to indicate whether the second cell supports multiplexing of the first signal.

[0275] It can be understood that each implementation of the method embodiment 500 has the same or corresponding technical features as the foregoing method embodiment 200, and thus each implementation of the method embodiment 500 can refer to the related description of the foregoing method embodiment 200 and achieve the same or corresponding technical effects. To avoid repetition, the details are not described herein again.
