[0044] In related communication technologies, DSS refers to Dynamic Spectrum Sharing, which allows technologies such as 4G LTE and 5G NR to share the same spectrum and dynamically allocate time and frequency resources to 4G and 5G users, thereby making it possible to deploy 4G cells and 5G cells simultaneously in the same frequency band.
[0045] The main advantages of DSS technology include the following a)-c).
[0046] a) Efficient use of spectrum resources: By dynamically allocating spectrum resources, DSS can adjust the use of 4G and 5G spectrum according to real-time demand, thereby improving spectrum utilization.
[0047] b) Smooth transition: Operators can gradually introduce 5G services without affecting existing 4G services, reducing the cost and complexity of spectrum reconfiguration.
[0048] c) Enhanced network performance: DSS can provide 5G services on existing frequency bands, improving network coverage and capacity.
[0049] Research has revealed that in 4G / 5G DSS, LTE and NR operate independently. The coexistence of LTE and NR can be understood as a coexistence with low system coupling. This leads to problems such as high signaling overhead when deploying cells supporting different radio access technologies on the same frequency band based on the DSS scheme, during cell camping, cell measurement, and other processes.
[0050] In this regard, taking 5G wireless access technology (hereinafter referred to as 5G or 5G NR or NR, etc.) and 6G wireless access technology (hereinafter referred to as 6G) as examples, this application considers that the design of physical layer signals can be reused to a certain extent during the evolution from 5G NR to 6G wireless access technology. For example, since the design of NR physical layer signals is more flexible, 6G physical layer signals may be able to directly reuse NR physical layer signals. Furthermore, 6G may need to design new physical layer signals for new 6G application scenarios (such as wireless sensing), including measurement signals based on frequency modulated continuous wave (FMCW) waveforms, while simultaneously reusing NR physical layer signals for data transmission, making the NR physical layer signals a subset of the physical layer signals supported by the 6G system. If 6G uses some or all of the NR physical layer signal design, the coexistence of 5G NR systems and 6G systems may be a coexistence with a high degree of system coupling. Based on this, this application provides a communication scheme that enables signal multiplexing under different wireless access technologies, solving problems such as high signaling overhead in processes such as cell camping and cell measurement under different wireless access technologies. The different wireless access technologies may include, but are not limited to, 4G, 5G, 6G, or other future wireless access technologies.
[0051] It should be noted that the terms "reuse," "share," "reuse," and "support reuse" mentioned in the context of this application have the same meaning, indicating that the first object can use the same signals and resources as the second object to perform a certain function or action. For example, if the second cell reuses the synchronization signal of the first cell, it means that the second cell can use the synchronization signal of the first cell to enable the synchronization function (of the terminal), etc.
[0052] Based on this, the technical solutions provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0053] like Figure 2 The diagram shown is a flowchart of a communication method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.
[0054] S210, the terminal acquires the first signal of the first cell.
[0055] S220, the terminal performs a target operation according to the first signal, the target operation including at least one of the following operations 1-3.
[0056] Operation 1: Obtain the second signal.
[0057] The second signal is used for the terminal to camp on the second cell or for the terminal to perform services corresponding to the second cell or to perform measurements in the second cell. The first cell and the second cell have different wireless access technologies, such as the first cell corresponding to 5G (or 6G) and the second cell corresponding to 6G (or 5G).
[0058] In other words, compared to related technologies where DSS requires sending a first signal through a second cell to obtain a second signal for stationing in the second cell, measuring in the second cell, or executing the service corresponding to the second cell, this embodiment can obtain a second signal by reusing the first signal of the first cell for stationing in the second cell or executing the service corresponding to the second cell. This reduces the need to send the second cell signal when stationing in the second cell, measuring, or enabling the service corresponding to the second cell on the terminal, thereby reducing signaling overhead, saving network energy, increasing system throughput, and achieving DSS with a certain degree of coupling between different wireless access technology systems.
[0059] Optionally, when the terminal camps on the second cell or performs the service corresponding to the second cell, it may do so based solely on the second signal, or it may do so based on both the first and second signals; no restriction is imposed here.
[0060] It should be noted that the phrase "services corresponding to the second cell" mentioned in this application context can be understood as: the services or characteristics of the radio access technology corresponding to the second cell, or the radio access technology services or characteristics corresponding to the second cell. For example, when the radio access technology corresponding to the second cell is 6G, the services corresponding to the second cell may include, but are not limited to, 6G wireless sensing services, network energy saving (NES), non-terrestrial network (NTN), RedCap terminal, artificial intelligence (AI) related enhancement features, etc.
[0061] The "measurement of the second cell" mentioned in the context of this application may include, but is not limited to: cell measurements during cell reselection or selection, cell measurements involved in executing services corresponding to the second cell, etc., without limitation.
[0062] In addition to the aforementioned first cell and second cell being 5G or 6G cells, in this embodiment, the first cell or second cell may also be a 4G cell, a 3G cell, or a cell corresponding to other future mobile communication technologies, etc., without any restrictions.
[0063] Operation 2: Perform measurements for the second cell. The first and second cells use different wireless access technologies; for example, the first cell may use 5G (or 6G), and the second cell may use 6G (or 5G).
[0064] In other words, compared to the situation in related technologies where the terminal needs to measure the second cell based on the signal sent by the second cell, this embodiment can achieve the measurement of the second cell by reusing the first signal of the first cell. This reduces the need to send the second cell signal when measuring the second cell, effectively reducing signaling overhead, saving network energy, and realizing DSS with a certain degree of coupling between different wireless access technology systems.
[0065] For example, in a multi-resolution spectrum sensing (MRSS) scenario, compared to related technologies that require intra-frequency cell reselection and inter-frequency cell reselection for second cell reselection evaluation, this embodiment considers that in a spectrum-sharing scenario, since the first cell and the second cell use the same or overlapping spectrum resources, cell measurement can be further achieved through signal sharing. For example, if the first cell and the second cell reuse the same first signal, then the measurement evaluation required by the terminal when performing cell selection or reselection for the second cell can be based on the first signal of the first cell. This reduces the need to transmit the second cell signal when measuring the second cell, lowers signaling overhead, and saves network energy.
[0066] Operation 3: Wake up the second cell.
[0067] In other words, compared to the situation in related technologies where the terminal needs to wake up the second cell based on the signal sent by the second cell, this embodiment can wake up the second cell by reusing the first signal of the first cell. This reduces the amount of signal sent by the second cell when waking up the second cell, effectively reducing signaling overhead, saving network energy, and realizing DSS with a certain degree of coupling between different wireless access technology systems.
[0068] In this embodiment, the terminal acquires a first signal from a first cell, and acquires a second signal based on the first signal, performs measurements of the second cell, or wakes up the second cell. The second signal is used by the terminal to camp on the second cell, perform services corresponding to the second cell, or perform measurements of the second cell. Thus, by reusing the signal of the first cell, the required transmission of the second cell signal can be reduced when camping on, measuring, waking up, or enabling services corresponding to the second cell on the terminal. This effectively reduces signaling overhead, saves network energy, increases system throughput, and achieves DSS with a certain degree of coupling between different wireless access technology systems.
[0069] Based on this, for operation 1 described in S220 above, that is, the terminal obtains the second signal according to the first signal, the method of obtaining the second signal provided in this embodiment may include, but is not limited to, at least one of the following methods 11-13.
[0070] Method 11: The terminal acquires the second signal from the first cell.
[0071] In method 11, when the terminal needs to camp on the second cell, the terminal can obtain the second signal from the first cell by reusing the first signal of the first cell to achieve camping on the second cell. In other words, by reusing the first and second signals of the first cell in the second cell in method 11, the required transmission of the second cell signal can be reduced when camping on the second cell. This avoids the problem of high signaling overhead caused by the second cell needing to transmit the first and second signals for cell camping in related technologies, thus saving network energy and increasing system throughput.
[0072] Regarding the execution of services corresponding to the second cell or the execution of measurements in the second cell, if the terminal supports the services corresponding to the second cell, regardless of whether the terminal is camped in the second cell or whether the terminal is in Radio Resource Control (RRC) connection mode in the second cell, the terminal can obtain the second signal of the first cell by multiplexing the first signal of the first cell, and then execute (or enable) the services corresponding to the second cell or perform measurements in the second cell through the second signal. In other words, in this method 11, the second cell can execute services corresponding to the second cell or perform measurements in the second cell by sharing the first and second signals of the first cell. This reduces the need to transmit signals from the second cell when enabling or executing services or measurements in the second cell on the terminal, avoiding the problem in related technologies where the terminal needs to camp in the second cell or be in RRC connection mode to execute services corresponding to the second cell. It also avoids the problem of high signaling overhead caused by the second cell needing to transmit a second signal for service execution, saving network energy and increasing system throughput.
[0073] Method 12: The terminal acquires the second signal from the second cell.
[0074] In method 12, the terminal obtains the second signal from the second cell by reusing the first signal of the first cell, thereby enabling camping in the second cell, executing services corresponding to the second cell, or performing measurements in the second cell. In other words, by reusing the first signal of the first cell in the second cell, method 12 reduces the amount of signal transmission required from the second cell when camping in the second cell, enabling services corresponding to the second cell on the terminal, or performing measurements in the second cell. This avoids the problem of high signaling overhead caused by the second cell needing to send a second signal for cell camping or service execution in related technologies, saving network energy and increasing system throughput.
[0075] Method 13: The terminal acquires the second signal from a third cell, wherein the third cell is indicated by the first cell and uses the same wireless access technology as the first cell.
[0076] In method 13, when the terminal needs to camp on the second cell, the terminal can obtain a second signal from the third cell by reusing the first signal of the first cell to achieve camping on the second cell. In other words, by reusing the first signal of the first cell and the second signal of the third cell in the second cell in method 13, the required signal transmission of the second cell can be reduced when camping on the second cell. This avoids the problem of high signaling overhead caused by the second cell needing to send the first and second signals for cell camping in related technologies, thus saving network energy and increasing system throughput.
[0077] Regarding the execution of services corresponding to the second cell or the execution of measurements in the second cell, if the terminal supports services corresponding to the second cell or the execution of measurements in the second cell, regardless of whether the terminal is camped in the second cell or whether the terminal is in an RRC connection state in the second cell, the terminal can obtain the second signal of the third cell by reusing the first signal of the first cell, and then use the second signal to implement services corresponding to the second cell or execute measurements in the second cell. In other words, in this method 13, the second cell can execute services corresponding to the second cell or execute measurements in the second cell by reusing the first signal of the first cell and the second signal of the third cell. This reduces the amount of signal transmission required from the second cell when enabling services corresponding to the second cell on the terminal or executing measurements in the second cell, avoiding the problem in related technologies where the terminal needs to camp in the second cell or be in an RRC connection state to execute services corresponding to the second cell. It also avoids the problem of high signaling overhead caused by the second cell needing to transmit the second signal, saving network energy and increasing system throughput.
[0078] It is worth noting that the third cell and the first cell may correspond to the same network-side device. For example, in this embodiment, the first cell may be the serving cell of the terminal, and the third cell may be an energy-saving cell indicated by the serving cell, etc.
[0079] Furthermore, the network-side equipment can be a physical base station or TRP, or a logical cell concept, and there are no restrictions here.
[0080] In some embodiments, for the aforementioned scenario of obtaining the second signal based on the first signal, such as methods 11-13, the process of the terminal obtaining the second signal may include, but is not limited to: the terminal may first obtain a target multiplexing pattern or signal resource configuration information; and then obtain the second signal from the second cell based on the target multiplexing pattern or signal resource configuration information. Wherein, 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 resources for the transmission of the second signal.
[0081] In other words, after receiving the first signal, the terminal can acquire the second signal based on the multiplexing pattern between the first and second signals, or based on the signal resource configuration information corresponding to the second signal. This improves the efficiency of acquiring the second signal and the reliability of the acquisition results.
[0082] It is understood that the target multiplexing pattern can be interpreted as an implicit indication of the transmission resources for the second signal transmission, while the signal resource configuration information can be interpreted as an explicit indication of the transmission resources for the second signal transmission. In this embodiment, the transmission resources for the second signal transmission may include, but are not limited to, time-domain resources, frequency-domain resources, signal period, signal pattern, etc.
[0083] Optionally, the acquisition methods for the target multiplexing pattern and the signal resource configuration information may include, but are not limited to, protocol agreements or configuration by the first cell. For example, in the case of configuration by the first cell, the target multiplexing pattern and / or the signal resource configuration information may be indicated by first indication information carried in the first signal. Optionally, the first signal may be, but is not limited to, RRC signaling, system messages, and Medium Access Control Element (MAC CE) signaling.
[0084] Furthermore, in some embodiments, the first indication information carried in the first signal can also be used to indicate whether the second signal exists. This allows the terminal to acquire the second signal based on the first indication information, avoiding invalid acquisition behavior that might occur when the terminal is unsure whether the second signal exists, thus avoiding signaling overhead and resource waste caused by invalid acquisition behavior. For example, if the first indication information indicates that the second signal does not exist, but the terminal still initiates a request to acquire the second signal based on the first signal, this results in invalid acquisition behavior.
[0085] Optionally, the first indication information can be carried through a reserved bit or an added bit in the first signal, without limitation. For example, when the reserved bit or the added bit is 1, it indicates that the second signal exists; otherwise, it indicates that it does not exist.
[0086] As an optional implementation, the first signal or the second signal mentioned in the foregoing implementations may include, but is not limited to, at least one of the following: synchronization signal, synchronization signal and PBCH block (SSB), physical broadcast channel (PBCH), master information block (MIB), system message, control signaling, tracking reference signal (TRS), positioning reference signal (PRS), demodulation reference signal (DMRS), and channel state information reference signal (CSI-RS).
[0087] The synchronization signal may include, but is not limited to, at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). For example, in this application, the synchronization signal may also be other reference signals that can be used for synchronization, such as new synchronization signals designed in future communication systems (e.g., 6G / 7G).
[0088] The system message may be, but is not limited to, System Information Block (SIB) 1 or other system information (OSI), etc.
[0089] The control signaling may be, but is not limited to, RRC signaling, MAC CE signaling, etc., and is not restricted here.
[0090] Based on this, in one alternative implementation, the first signal and the second signal may satisfy, but are not limited to, at least one of the following 11)-16).
[0091] 11) The first signal is PSS, and the second signal includes at least one of SSS, SSB, PBCH, and MIB.
[0092] 12) The first signal is SSS, and the second signal includes at least one of PSS, SSB, PBCH, and MIB.
[0093] 13) The first signal is PSS and SSS, and the second signal includes at least one of SSB, PBCH, and MIB.
[0094] 14) The first signal is SSB, and the second signal includes at least one of SSB, PBCH, MIB, and SIB.
[0095] 15) The first signal includes a system message or control signaling, and the second signal includes at least one of SSB, PBCH, MIB, and system message.
[0096] 16) The first signal is a first DMRS, and the second signal is a second DMRS, wherein the first DMRS and the second DMRS are located in different time units. The time unit can be a symbol, a time slot, a subframe, etc., and is not limited here.
[0097] In some embodiments, when the first signal is the synchronization signal (such as PSS or SSS) or SSB, and the second signal includes 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 problems such as transmission resource conflicts. The second signal can be the PBCH, or a synchronization signal including the PBCH, SSB, MIB, etc.
[0098] In some embodiments, when both the first signal and the second signal are the PBCH, the MIB, or the system message, the information carried in the second signal differs from the information carried in the first signal, or the information carried in the second signal does not include information already carried in the first signal. That is, relative to the information carried in the first signal, the second signal may carry additional information, such as additional SIB1, additional OSI, etc. This avoids the resource waste caused by duplicate transmissions.
[0099] In some embodiments, the process by which the terminal obtains the second signal based on the first signal in S210 may include, but is not limited to: if the first signal carries target configuration information, the terminal obtains the second signal based on the target configuration information. The target configuration information is used to indicate request configuration information for the terminal to obtain the second signal, and the target configuration information corresponds to the first cell, the second cell, or the third cell.
[0100] In this embodiment, the second signal may include, but is not limited to, on-demand signals, such as on-demand (OD)-SSB, NES OD-SIB1, 6G OD-PBCH, etc. Correspondingly, the target configuration information may also be referred to as on-demand signal request configuration information corresponding to the first cell, the second cell, or the third cell, for requesting the on-demand signal or other second signals, and then, based on the requested second signal, performing camping in the second cell, executing (or enabling) the services corresponding to the second cell, or performing measurements in the second cell, etc.
[0101] Based on this, as an optional implementation, when the target configuration information corresponds to the first cell or the third cell, the process by which the terminal obtains the second signal according to the target configuration information may include, but is not limited to: when the terminal determines that the target configuration information corresponds to the target cell (such as the first cell or the third cell) and the second signal corresponding to the target cell can be used for camping in the second cell or for the 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.
[0102] In other words, in this implementation, the terminal does not need to know whether the first or third cell supports the second cell or the service corresponding to the second cell. It only needs to determine whether to request the second signal from the first or third cell based on whether the second signal can be used for camping in the second cell, for the service corresponding to the second cell, or for measurement in the second cell. For example, if the second signal can be used for camping in the second cell, for the service corresponding to the second cell, or for measurement in the second cell, then the terminal can request the second signal from the first or third cell.
[0103] Based on this, as an optional implementation, when the target configuration information corresponds to the first cell or the third cell, the target configuration information can also be called the on-demand signal request configuration information corresponding to the first cell or the third cell, so as to allow the terminal to request a second signal from the first cell or the third cell.
[0104] Optionally, the target configuration information corresponding to the first cell or the third cell may include, but is not limited to, at least one of 21)-24).
[0105] 21) The type of the second signal, such as SSB, TRS, PRS, DMRS, etc.
[0106] 22) Resource configuration of the second signal, such as time domain resources, frequency domain resources, signal period, signal pattern, etc.
[0107] 23) Used to request resource configuration for the second signal, such as configuration information related to message 1 (Msg1) of the random access process (or preamble configuration information) and configuration information related to Msg3; the Msg1 / Msg3 are used to request on-demand signals from the first network-side device.
[0108] 24) Identifier of the first network-side device. The first network-side device corresponds to the target cell, such as the network-side device corresponding to the first cell and / or the third cell. The network-side devices corresponding to the first cell and the third cell may be the same or different.
[0109] Optionally, the identifier of the first network-side device may include, but is not limited to, Physical Cell Identifier (PCI), cell ID, base station identifier (gNB-ID), etc.
[0110] Optionally, the terminal may determine in various ways whether the second signal corresponding to the target cell (such as the first cell or the third cell) can be used for camping in the second cell, or for services or measurements in the second cell.
[0111] In one implementation, the terminal can determine, based on the type of the second signal included in the target configuration information and the terminal's capabilities, whether the second signal corresponding to the target cell can be used for camping in the second cell, for services corresponding to the second cell, or for measurements in the second cell. For example, if the terminal supports reusing the second signal (such as 5G PRS) of a 5G cell (i.e., the first cell) to execute services corresponding to the second cell (i.e., the 6G cell), such as 6G wireless sensing services, and the type of the second signal included in the target configuration information includes PRS, then the terminal can initiate a request to acquire the 5G PRS from the target cell according to the target configuration information; otherwise, the terminal cannot initiate a request to acquire the second signal.
[0112] In another implementation, if the first signal further includes second indication information, the terminal can determine, based on the second indication information, that the second signal corresponding to the target cell can be used for camping in the second cell, or for services or measurements in the second cell; wherein, the second indication information is used to indicate that the second cell or services corresponding to the second cell support the reuse of the second signal corresponding to the target cell (such as the first cell or the third cell), such as wireless sensing, AI+X (AI-assisted X, AI-enhanced X), etc.
[0113] For example, when the terminal is ready to execute a 6G wireless sensing feature application, and the second indication information indicates that the 6G wireless sensing feature supports the reuse of the second signal of the target cell, then the terminal may initiate a request to obtain the second signal according to the target configuration information.
[0114] Optionally, the second indication information may carry, but is not limited to, the target configuration information.
[0115] In addition, besides determining through the aforementioned method whether the second signal corresponding to the target cell can be used for camping in the second cell, or for services or measurements in the second cell, the terminal can also be configured with information such as whether the second signal corresponding to the target cell can be used for camping in the second cell, or for services or measurements in the second cell, through protocol agreements or other means, without any restrictions.
[0116] Except for the case where the target configuration information corresponds to the first cell or the third cell, when the target configuration information corresponds to the second cell, the process by which the terminal obtains the second signal based on the target configuration information may include, but is not limited to: when it is determined that the target configuration information corresponds to the second cell, the terminal requests the network-side device corresponding to the second cell to obtain the second signal for the purpose of the terminal camping on the second cell, performing the service corresponding to the second cell, or performing the measurement of the second cell, etc.
[0117] Optionally, the target configuration information corresponding to the second cell may include, but is not limited to, at least one of the following 31)-34).
[0118] 31) Signal configuration information, used to indicate the relevant configuration of the second signal of the second cell.
[0119] Optionally, the signal configuration information includes, but is not limited to, at least one of 31a)-31d).
[0120] 31a) The type of the second signal, such as SSB, MIB (or PBCH), SIB, TRS, PRS, DMRS, etc.
[0121] 31b) Resource configuration of the second signal, such as time domain resources, frequency domain resources, signal period, signal pattern, etc.
[0122] 31c) is used to request resource configuration for the second signal, such as Msg1 related configuration information (or preamble configuration information) and Msg3 related configuration information; Msg1 / Msg3 is used to request on-demand signals from the network-side equipment corresponding to the second cell or the first cell.
[0123] 31d) Identifier of the second network-side device. The second network-side device is the network-side device corresponding to the second cell or the first cell. Optionally, the identifier of the second network-side device may include, but is not limited to, PCI, cellID, gNB-ID, etc.
[0124] 32) The third indication information is used to indicate the services supported by the second cell, such as wireless sensing services, network energy saving, non-terrestrial networks, limited capability terminals, AI-related enhancement features, etc.
[0125] 33) Fourth indication information, used to indicate the signal of the first cell (such as the first signal, second signal, etc. of the first cell) that the second cell or the service corresponding to the second cell supports multiplexing.
[0126] The phrase “signals of the first cell that the second cell supports reuse” can be understood as signals of the first cell that support reuse of one or more processes in the second cell, such as one or more of the following: cell measurement, cell camping, and enabling of services corresponding to the cell.
[0127] The phrase "the second cell supports the reuse of the signal from the first cell" can be understood as: the second cell supports the reuse of the signal from the first cell, and / or, the signal configuration information of the second cell supporting the reuse of the signal from the first cell, such as resource configuration information, signal type, etc. The resource configuration may include, but is not limited to, time-domain resources, frequency-domain resources, signal period, etc., and the signal type includes SSB, TRS, PRS, DMRS, etc.
[0128] For example, assuming that the service corresponding to the second cell includes wireless sensing features or artificial intelligence-related enhancement features, then the fourth indication information can indicate that the measurement signal of the wireless sensing features or artificial intelligence-related enhancement features supports the reuse of the SSB, PRS, etc. of the first cell.
[0129] 34) Fifth indication information, used to indicate the signal of the first cell that is being reused by the second cell or the service corresponding to the second cell, such as the first signal or the second signal.
[0130] In this context, "the signal of the first cell being reused by the second cell" can be understood as one or more processes being reused by the first cell in the second cell, such as cell measurement, cell camping, or enabling of the corresponding services in the second cell.
[0131] The phrase "the signal of the first cell being reused by the second cell" can be understood as: the signal of the first cell being reused by the second cell, and / or the signal configuration information of the signal of the first cell being reused by the second cell, such as resource configuration information, signal type, etc. The resource configuration may include, but is not limited to, time-domain resources, frequency-domain resources, signal period, etc., and the signal type includes SSB, TRS, PRS, DMRS, etc.
[0132] For example, assuming the second cell is reusing the SSB of the first cell to enable the terminal's Radio Resource Management (RRM) measurement, synchronization, and other functions, then 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 needing to request the synchronization signal or synchronization signal block of the second cell.
[0133] It should be noted that if the target configuration information does not exist, then when the terminal believes or assumes that it needs to request the signal necessary to camp on the second cell, it needs to request the complete synchronization signal or synchronization signal block of the second cell.
[0134] In some embodiments, when the target configuration information corresponds to the second cell, the process by which the terminal requests the second signal from the network-side device corresponding to the second cell based on the target configuration information may include, but is not limited to: the terminal, upon determining that a first condition is met, requests the second signal from the network-side device corresponding to the second cell based on the target configuration information. This ensures that the terminal obtains the second signal that meets its requirements.
[0135] The first condition may include, but is not limited to, at least one of the following conditions 1-5.
[0136] Condition 1: The terminal supports the reuse of signals from the first cell (such as the first signal and the second signal) in the second cell to camp on the second cell, perform services corresponding to the second cell, or perform measurements in the second cell. In other words, the terminal can determine which second signal to request based on the signals it can support for reuse.
[0137] For example, assuming the first cell is a 5G cell and 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 camping on the second cell, then, if the terminal's capability supports reusing 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, as needed according to the target configuration information to camp on the 6G cell.
[0138] If the terminal does not support reusing the SSB of the 5G cell for time-frequency synchronization or ACG, then 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.
[0139] For example, Figure 3a The paper demonstrates a possible design scheme for 5G and 6G SSB, in which the 6G SSB can reuse the PSS and / or SSS portions of the 5G SSB.
[0140] When 6G cells follow Figure 3b When the 6G terminal does not send (periodic) 6G PBCH, if the 6G terminal can perform synchronization based on 5G SSB, the terminal only needs to request the second signal, i.e., 6G OD-PBCH; if the 6G terminal does not support synchronization based on 5G SSB, it needs to request the complete 6G SSB (including cell synchronization signal and MIB).
[0141] Condition 2: The terminal supports the reuse of the first signal of the first wireless access technology by the second wireless access technology, so as to camp in the second cell, perform services corresponding to the second cell, or perform measurements in the second cell, etc. Wherein, the second wireless access technology is the wireless access technology corresponding to the second cell, and the first wireless access technology is the wireless access technology corresponding to the first cell or the third cell.
[0142] For example, if the wireless access technology corresponding to the first cell is 5G and the wireless access technology corresponding to the second cell is 6G, then the terminal can request the second signal from the first cell or the second cell according to the target configuration information, provided that the 6G reuses the first signal of 5G, in order to perform activities such as camping in the second cell, measuring the second cell, and enabling the services corresponding to the second cell.
[0143] It is worth noting that the aforementioned condition 1 can also be understood as a possible implementation of condition 2. For example, if the terminal determines that condition 2 is met, it can further determine that the terminal supports the reuse of the signal of the first cell under the first radio access technology by the second cell under the second radio access technology.
[0144] Condition 3: The services supported by the second cell indicated by the third indication information include: the services corresponding to the second cell supported by the terminal, or the services corresponding to the second cell that the terminal needs to initiate.
[0145] For example, if the service corresponding to the second cell indicated by the third indication information includes wireless sensing, then a terminal that supports wireless sensing, or a terminal that is preparing to execute wireless sensing services, can initiate a request for the second signal (or on-demand signal) according to the target configuration information in order to perform tasks such as camping on the second cell, measuring the second cell, and enabling the services corresponding to the second cell.
[0146] Condition 4: The signals of the second cell or the first cell whose services are supported for reuse by the second cell indicated by the fourth indication information include: the signals of the first radio access technology supported for reuse by the terminal, such as the signals of the first cell supported for reuse by the terminal (such as the first signal, the second signal, etc.).
[0147] For example, when a terminal is preparing to execute a wireless sensing feature application, the wireless sensing feature application supports the reuse of the signal of the first cell, and the fourth indication information indicates that the second cell or the service corresponding to the second cell supports the reuse of the first signal to execute the wireless sensing feature, the terminal can initiate a request for the second signal according to the target configuration information to perform camping in the second cell, measurement of the second cell, and enabling of the service corresponding to the second cell.
[0148] Condition 5: The signals of the second cell or the first cell whose services are being reused by the second cell indicated by the fifth indication information include: signals of the first radio access technology that the terminal supports reuse, such as signals of the first cell that the terminal supports reuse (e.g., first signal, second signal, etc.).
[0149] In some embodiments, when the terminal acquires the second signal as described above, the terminal can also determine the cell identifier of the second cell according to any one of the following 41)-43). This can be used for associating configuration information related to the second cell and receiving the signal corresponding to the second cell (such as signal decoding or descrambling).
[0150] 41) The first signal, or the correlation function value of the first signal, wherein the first signal includes at least one of PBCH, PSS and SSS.
[0151] In this context, when determining the cell identifier of the second cell based on the first signal, it can be understood that the identifier of the second cell can reuse the identifier of the first cell determined based on the first signal.
[0152] When determining the identifier of the second cell based on the correlation function value of the first signal, the correlation function value of the first signal may also be related to other parameters. For example, the other parameters may include, but are not limited to, the PBCH and DMRS corresponding to the second cell.
[0153] It is worth noting that the correlation function values of the first signal and the second signal can be understood as being obtained by calculating the first signal using a correlation function (such as a linear function). For example, the correlation function values can be obtained by performing linear calculations on the first signal using a linear function, etc. This embodiment does not impose any restrictions on this.
[0154] 42) The second signal, wherein the second signal includes PBCH.
[0155] 43) The first signal and the second signal, or the correlation function value of the first signal and the second signal, wherein the first signal includes PSS and the second signal includes SSS, or the first signal includes SSS and the second signal includes PSS.
[0156] It is worth noting that the correlation function values of the first signal and the second signal can be understood as being obtained by calculating the first signal and the second signal using a correlation function (such as a linear function). For example, the correlation function values can be obtained by performing linear calculations on the first signal and the second signal using a linear function, etc. This embodiment does not impose any restrictions on this.
[0157] Optionally, the cell identifier of the second cell is used for decoding (or descrambling) the second signal, wherein the second signal includes the PBCH. For example, if the scrambling of the second signal is related to the identifier of the second cell, the identifier of the second cell can be used for decoding the second signal.
[0158] In some embodiments, operation 2 in the aforementioned S220, namely the implementation of the terminal performing the measurement of the second cell based on the first signal of the first cell, may include, but is not limited to, any one of the following methods 21-22.
[0159] Method 21: The terminal measures the target information of the second cell based on the first signal.
[0160] The target information includes at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indication (RSSI), Signal-to-noise and interference ratio (SINR), System frame number (SFN), SFN time difference, Reference Signal time difference, Frame time difference, Channel occupancy rate, Channel busy rate, Transmit / receive time difference, Carrier phase, or Downlink time offset.
[0161] Correspondingly, the first signal may include, but is not limited to, at least one of PSS, SSS, SS, DMRS, Channel State Information Reference Signal (CSI-RS), TRS, and PRS.
[0162] In other words, when the terminal needs to perform measurements on the second cell, and the signal sent by the first cell is a synchronization signal, SSS, PSS, DMRS, CSI-RS, TRS, PRS, etc., the terminal can perform measurements based on the aforementioned signals sent by the first cell to obtain measurement quantities such as RSRP, RSRQ, RSSI, SINR, SFN, SFN time difference, reference signal time difference, frame time difference, channel occupancy rate, channel busy rate, transmit / receive time difference, carrier phase or downlink time offset, etc. This enables the reduction of the required transmission of signals from the second cell when performing measurements on the second cell.
[0163] In some embodiments, the network-side device may instruct the terminal which measurements of the second cell can reuse which type or class of signal from the first cell for measurement.
[0164] Method 22: The terminal measures the target information of the second cell based on the first signal and the second signal.
[0165] The implementation of method 22 is similar to that of method 21, but differs in that, in method 22, when measuring the second cell, in addition to reusing the first signal, the second signal can also be combined. For example, during a measurement of the second cell, some measurements can be obtained based on the first signal, while other measurements can be obtained based on the second signal.
[0166] For example, the terminal can first reuse the first signal to camp on the second cell, and then perform measurements on the second cell based on the second signal of the second cell.
[0167] It is worth noting that the first and second signals described in methods 21 and 22 can be referred to the relevant descriptions above, and will not be repeated here. For example, the second signal can be obtained based on the aforementioned target multiplexing pattern or target configuration information.
[0168] 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 understand the terminal's capabilities, thereby making the relevant information configured or sent for the terminal (such as target configuration information, second signals, etc.) match the terminal's capabilities.
[0169] The terminal capability information is used to indicate at least one of the following 51)-53).
[0170] 51) The terminal supports the second cell reusing the signals of the first cell or the third cell. For example, the first signal and the second signal of the first cell, the second signal of the third cell, etc.
[0171] 52) The terminal supports the second wireless access technology to reuse the first signal of the first wireless access technology, wherein the second wireless access technology is the wireless access technology corresponding to the second cell, and the first wireless access technology is the wireless access technology corresponding to the first cell or the third cell.
[0172] It is worth noting that 51) above can also be understood as a possible implementation of 52). For example, if the terminal supports the reuse of the first signal of the first wireless access technology as described in 52), then it can be determined that the terminal supports the reuse of the first signal of the first cell under the second wireless access technology by the second cell.
[0173] 53) The terminal supports the services corresponding to the second cell.
[0174] In some embodiments, the network-side device corresponding to the first cell or the second cell may also send a sixth indication message to the terminal to indicate whether the second cell 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 to perform measurements in the second cell. This ensures that the terminal and the network-side device have a consistent understanding of the first signal.
[0175] In this case, if the sixth indication information indicates that the second cell supports reusing the first signal of the first cell, then the terminal can obtain the second signal based on the first signal, or perform a measurement of the second cell based on the first signal.
[0176] In the aforementioned communication scheme provided in this application, by reusing the signal of the first cell in the second cell, the number of signals that the second cell needs to send to enable the terminal to camp in the second cell, measure or execute the application corresponding to the second cell can be reduced, thereby reducing signaling overhead and achieving network energy saving and increasing the available resources / throughput of the system.
[0177] Based on the foregoing description of the communication method, for ease of understanding, the communication method provided in the embodiments of this application is described exemplarily below, the content of which is as follows.
[0178] Example 1: The second cell reuses the first signal of the first cell to achieve cell dwell.
[0179] Assuming the first cell is a 5G cell and the second cell is a 6G cell, and the 6G cell can reuse the first signal of the 5G cell, such as the PSS or SSS of the SSB, then the terminal only needs to send the second signal, such as the 6G PBCH or 6G SIB1, to enable the terminal to camp on the 6G cell. This reduces the number of signals that the second cell needs to send to enable the terminal to camp on the second cell, thereby reducing signaling overhead and achieving network energy saving and increased system available resources / throughput.
[0180] Among them, such as Figure 3a As shown, if a target multiplexing pattern is configured through network-side configuration or protocol agreement, then after the terminal detects the 5G SSB, it can detect the 6GPBCH according to the target multiplexing pattern and the 5G SSB. Then, the terminal can obtain the 6G SIB1 reception configuration based on the detected 6G PBCH to obtain SIB1.
[0181] Optionally, in the case where the target multiplexing pattern is configured on the network side, after the terminal receives the 5G SSB and camps on the 5G cell according to the 5G SSB instruction, it can obtain the target multiplexing pattern through the configuration information of the 5G cell (such as OSI other than SIB).
[0182] Optionally, such as Figure 3a As shown, the PBCH of the 5G SSB may carry first indication information to indicate whether the 6G PBCH exists. If it exists, the terminal performs the aforementioned steps of detecting the 6G PBCH according to the target multiplexing pattern and the 5G SSB; otherwise, it stops detecting the 6G PBCH.
[0183] The first indication information can be carried in a 1-bit reserved bit in the NR PBCH. For example, when the 1-bit reserved bit is set to 1, it means that the 6G PBCH exists; otherwise, it means that it does not exist.
[0184] Optionally, after receiving a 5G SSB and camping on a 5G cell according to the 5G SSB instruction, the terminal can obtain a 6G PBCH or a 6G SIB1 through the target configuration information of the 5G cell.
[0185] Optionally, the identifier of the 6G cell can be determined by at least one of the following a)-d).
[0186] a) The first signal of the 5G cell, such as the PSS or SSS of the SSB, i.e. the identifier of the 6G cell, can reuse the cell ID determined by the PSS or SSS of the 5G cell.
[0187] b) The relevant function value of the first signal of the 5G cell (such as the PSS or SSS of the SSB), that is, the function value of the cell ID determined based on the PSS or SSS of the 5G cell for identifying the 6G cell.
[0188] Optionally, the function value can also be related to other parameters, such as 6G PBCH, DMRS, etc.
[0189] c) NR PBCH or 6G PBCH
[0190] d) The PSS of the 5G cell and the SSS of the 6G cell, or the SSS of the 5G cell and the PSS of the 6G cell.
[0191] Among them, the identifier of the 6G cell determined based on the above a)-d) can be used for the decoding of 6G PBCH, such as the scrambling of 6GPBCH being related to the identifier of the 6G cell.
[0192] Similarly, for the case where the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to that of the case where the first cell is a 5G cell and the second cell is a 6G cell, and will not be repeated here.
[0193] Example 2: The second signal originates from the first cell and is used by the terminal to camp on the second cell, execute services corresponding to the second cell, and perform measurements on the second cell, etc.
[0194] Assuming the first cell is a 5G cell (i.e., the serving cell) and the second cell is a 6G cell, then, if Figure 4a As shown, the process by which the terminal acquires the second signal is as follows.
[0195] S411, the 5G cell (or the network-side equipment corresponding to the first cell) sends the first signal to the terminal.
[0196] The first signal carries target configuration information, and the target configuration information corresponds to the first cell.
[0197] 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 to perform the service corresponding to the second cell or to perform the measurement of the second cell. If so, then S413 is executed; otherwise, the terminal cannot initiate a request to obtain the second signal.
[0198] S413, a signal request message is sent to the 5G cell according to the target configuration information to request the second signal (also known as an on-demand signal).
[0199] S414, the first cell sends a signal request response message to the terminal according to the signal request message.
[0200] Optionally, the signal request response message may include the second signal, or the signal request response message may not include the second signal, but may only serve as a response message to indicate that the request message was sent successfully.
[0201] Wherein, if the signal request response message does not include a second signal, the first cell may send a second signal to the terminal via S415, without any restrictions.
[0202] S415, the first cell sends a second signal to the terminal according to the signal request message.
[0203] The terminal can stay in the second cell or perform services corresponding to the second cell, or perform measurements of the second cell, etc., based on the second signal.
[0204] In Example 2, when the terminal supports 5G and 6G DSS capabilities, it can request a second signal from the 5G cell through target configuration information corresponding to the 5G cell. This signal is used for the terminal to camp on the second cell, perform services corresponding to the second cell, or perform measurements on the second cell. Therefore, on the one hand, when enabling 6G applications on the terminal, camping on a 6G cell, or performing measurements on a 6G cell, the required transmission of 6G signals is reduced, signaling overhead is lowered, and corresponding network energy-saving gains are achieved. In particular, by reusing the second signal from the 5G cell to perform services corresponding to the 6G cell or to perform measurements on the 6G cell, the terminal does not need to activate the 6G cell. On the other hand, the terminal does not need to know whether the 5G cell supports 6G services, whether it can camp on a 6G cell, or whether it can perform measurements on a 6G cell. It only needs to decide whether to request the second signal from the 5G cell based on whether the second signal can be used for services corresponding to the 6G cell, camping on a 6G cell, or performing measurements on a 6G cell, thereby reducing the complexity of obtaining the second signal.
[0205] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to that in Example 2 above, and will not be repeated here to avoid repetition.
[0206] It is understood that the relevant steps of this Example 2 can be referred to the relevant description in the foregoing method embodiment 200, and will not be repeated here to avoid repetition. In addition, this Example 2 may include, but is not limited to, the foregoing S411-S415, that is, it may include more or fewer steps than described above.
[0207] Example 3: The second signal originates from the third cell, and is used by the terminal to camp on the second cell, execute services corresponding to the second cell, and perform measurements on the second cell, etc.
[0208] Assuming the first cell is a 5G cell (i.e., the serving cell) and the second cell is a 6G cell, then, if Figure 4b As shown, the process by which the terminal acquires the second signal is as follows.
[0209] S421, the 5G cell (or the network-side equipment corresponding to the first cell) sends the first signal to the terminal.
[0210] The first signal carries target configuration information, and the target configuration information corresponds to the 5G cell (i.e., the third cell).
[0211] 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 to perform the service corresponding to the second cell or to perform the measurement of the second cell. If so, then S423 is executed; otherwise, the terminal cannot initiate a request to obtain the second signal.
[0212] S423, a signal request message is sent to the 5G cell (i.e., the third cell) according to the target configuration information to request the second signal (also known as an on-demand signal).
[0213] S424, the third cell sends a signal request response message to the terminal according to the signal request message.
[0214] Optionally, the signal request response message may include the second signal, or the signal request response message may not include the second signal, but may only serve as a response message to indicate that the request message was sent successfully.
[0215] Wherein, if the signal request response message does not include a second signal, the first cell may send a second signal to the terminal via S425, without any restrictions.
[0216] S425, the third cell sends a second signal to the terminal according to the signal request message.
[0217] The terminal can stay in the second cell or perform services corresponding to the second cell, or perform measurements of the second cell, etc., based on the second signal.
[0218] In Example 3, when the terminal supports 5G and 6G DSS capabilities, it can request a second signal from the 5G cell (i.e., the third cell) through target configuration information corresponding to the 5G cell. This signal is used for the terminal to camp on the second cell, perform services corresponding to the second cell, or perform measurements on the second cell. This reduces the required 6G signal transmission, lowers signaling overhead, and achieves corresponding network energy-saving gains when enabling 6G applications or camping on or measuring the second cell in the 6G cell. In particular, by reusing the second signal from the 5G cell to perform services corresponding to the 6G cell or to perform measurements on the 6G cell, the terminal does not need to activate the 6G cell. Furthermore, the terminal does not need to know whether the 5G cell supports 6G services, whether it can camp on the 6G cell, or whether it can perform measurements on the 6G cell. It only needs to decide whether to request the second signal from the 5G cell based on whether the second signal can be used for services or camping on the 6G cell, thereby reducing the complexity of obtaining the second signal.
[0219] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to that in Example 3 above, and will not be repeated here to avoid repetition.
[0220] It is understood that the relevant steps of this Example 3 can be referred to the relevant description in the foregoing method embodiment 200, and will not be repeated here to avoid repetition. In addition, this Example 3 may include, but is not limited to, the foregoing S421-S425, that is, it may include more or fewer steps than described above.
[0221] Example 4: The second signal originates from the second cell, and is used by the terminal to camp on the second cell, execute services corresponding to the second cell, and perform measurements on the second cell, etc.
[0222] Assuming the first cell is a 5G cell (i.e., the serving cell) and the second cell is a 6G cell, then, if Figure 4c As shown, the process by which the terminal acquires the second signal is as follows.
[0223] S431, the 5G cell (or the network-side equipment corresponding to the first cell) sends the first signal to the terminal.
[0224] The first signal carries target configuration information, and the target configuration information corresponds to the 6G cell (i.e., the second cell).
[0225] S432, if the terminal determines whether the first condition is met, then if it is, then execute S433; otherwise, it cannot initiate a request to obtain the second signal.
[0226] The first condition can be referred to in the relevant description in the aforementioned method embodiment 200, and will not be repeated here.
[0227] S433, a signal request message is sent to the 6G cell (i.e., the second cell) according to the target configuration information to request the second signal (also known as an on-demand signal).
[0228] S434, the second cell sends the signal request response message to the terminal according to the signal request message.
[0229] Optionally, the signal request response message may include the second signal, or the signal request response message may not include the second signal, but may only serve as a response message to indicate that the request message was sent successfully.
[0230] Wherein, if the signal request response message does not include a second signal, the first cell may send a second signal to the terminal via S415, without any restrictions.
[0231] S435, the second cell sends a second signal to the terminal according to the signal request message.
[0232] The terminal can stay in the second cell or perform services corresponding to the second cell, or perform measurements of the second cell, etc., based on the second signal.
[0233] If the second signal is used for the terminal to camp on the 6G cell or to perform the service corresponding to the 6G cell, then it can be understood that the terminal can reuse the first signal of the 5G cell and combine it with 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 measurements of the second cell, etc.
[0234] For example, if the terminal's capabilities support time-frequency synchronization and automatic gain control (AGC) using 5G SSB, then in order to camp on a 6G-enabled cell, the terminal only needs to request the 6G cell's MIB or SIB1 from the 6G cell. Otherwise, the terminal needs to request the cell synchronization signal, MIB, or SIB1 of the second cell from the 6G cell.
[0235] Optionally, the signal configuration information carried in the target configuration information may include the MIB of the 6G cell. In other words, the terminal only uses the synchronization signal portion of the SSB of the 5G cell to complete time-frequency synchronization and AGC.
[0236] Compared to Examples 2 and 3, where only the 5G cell sends a second signal to camp on the 6G cell, execute services corresponding to the 6G cell, or perform measurements on the 6G cell, in Example 4, the 5G cell can indicate a wakeable 6G cell (or 6G network-side equipment) or target configuration information corresponding to the 6G cell to obtain a second signal from the 6G cell, execute services corresponding to the 6G cell, camp on the 6G cell, or perform measurements on the 6G cell. This reduces the amount of signal transmission required from the second cell when camping on or measuring in the second cell or enabling services corresponding to the second cell on the terminal, lowering signaling overhead and achieving corresponding network energy-saving gains.
[0237] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to that in Example 3 above, and will not be repeated here to avoid repetition.
[0238] It is understood that the relevant steps of this Example 3 can be referred to the relevant description in the foregoing method embodiment 200, and will not be repeated here to avoid repetition. In addition, this Example 3 may include, but is not limited to, the foregoing S431-S435, that is, it may include more or fewer steps than described above.
[0239] Example 5: The second signal comes from the first cell and is used by the terminal to camp on the second cell, execute services corresponding to the second cell, and perform measurements on the second cell.
[0240] Assuming the first cell is a 5G cell and the second cell is a 6G cell, then, if Figure 4d As shown, the process by which the terminal acquires the second signal is as follows.
[0241] S441, the 5G cell (or the network-side equipment corresponding to the first cell) sends the first signal to the terminal.
[0242] The first signal carries target configuration information, and the target configuration information corresponds to the 6G cell (i.e., the second cell).
[0243] S442, if the terminal determines whether the first condition is met, then if it is, then execute S433; otherwise, it cannot initiate a request to obtain the second signal.
[0244] The first condition can be referred to in the relevant description in the aforementioned method embodiment 200, and will not be repeated here.
[0245] 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 known as an on-demand signal).
[0246] S454, the first cell sends a signal request response message to the terminal according to the signal request message.
[0247] Optionally, the signal request response message may include the second signal, or the signal request response message may not include the second signal, but may only serve as a response message to indicate that the request message was sent successfully.
[0248] Wherein, if the signal request response message does not include a second signal, the first cell may send a second signal to the terminal via S415, without any restrictions.
[0249] S445, the first cell sends a second signal to the terminal according to the signal request message.
[0250] The terminal can stay in the second cell or perform services corresponding to the second cell, or perform measurements of the second cell, etc., based on the second signal.
[0251] Compared to Example 4, where the terminal requests a second signal from the 6G cell based on the target configuration information corresponding to the 6G cell to camp on, measure, or execute services corresponding to the 6G cell, in Example 5, the terminal requests a second signal from the 5G cell based on the target configuration information corresponding to the 6G cell to camp on, measure, or execute services corresponding to the 6G cell. This reduces the amount of signal transmission required from the second cell when camping on, measuring, or enabling services corresponding to the second cell on the terminal, thereby lowering signaling overhead and achieving corresponding network energy-saving gains.
[0252] Similarly, when the first cell is a 6G cell and the second cell is a 5G cell, the implementation process is similar to that in Example 5 above, and will not be repeated here to avoid repetition.
[0253] It is understood that the relevant steps of this Example 5 can be referred to the relevant description in the foregoing method embodiment 200, and will not be repeated here to avoid repetition. In addition, this Example 5 may include, but is not limited to, the foregoing S441-S445, that is, it may include more or fewer steps than described above.
[0254] Example 6: Measurement of the second cell
[0255] Assuming the first cell is a 5G cell and the second cell is a 6G cell, in the spectrum-sharing scenario of this application, the 5G cell and the 6G cell use the same or overlapping spectrum resources. That is, based on spectrum sharing, the 5G cell and the 6G cell further measure the 6G cell through signal sharing. For example, the 6G cell can be measured based on the first signal of the 5G cell, or it can be measured based on 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.
[0256] If the 5G cell and the 6G cell reuse the same SSS, then the terminal's RSRP / RSRQ measurement and evaluation of cell selection or reselection of the 6G cell can be based on the SSS of the 5G cell.
[0257] For example, assuming that the signal transmitted by the 5G cell is PSS, SSS, SSB, DMRS, CSI-RS, TRS, or PRS, then when the terminal UE is measured in the 6G cell, the measurement quantities such as RSRP, RSRQ, RSSI, SINR, SFN, SFN time difference, reference signal time difference, frame time difference, channel occupancy rate, channel busy rate, transmit / receive time difference, carrier phase, or downlink time offset, etc., can be based on one or more of the PSS, SSS, SSB, DMRS, CSI-RS, TRS, or PRS transmitted by the 5G cell.
[0258] Considering the limited number of PSS sequences (e.g., three), PSS-based measurements may be inaccurate. Therefore, when performing RSRP or RSRQ measurements for 6G cells, other signals besides PSS should be used preferentially.
[0259] Optionally, in this Example 6, the terminal supports reusing the signal of a 5G cell for 6G cell measurement.
[0260] Optionally, in Example 6, the network-side device may instruct the 6G cell to reuse the signal from the 5G cell for measurement. For example, the network-side device may instruct the 6G cell to perform a specific measurement and to reuse a particular type or category of signal from the 5G cell for measurement.
[0261] like Figure 5 The diagram shown is a flowchart of a communication method 500 provided in an exemplary embodiment of this application. This method 500 can be executed by, but is not limited to, a network-side device, specifically by hardware and / or software installed in the network-side device. In this embodiment, the method 500 may include at least the following steps.
[0262] S510, the network-side device sends the first signal to the terminal.
[0263] The network-side device corresponds to the first cell, and the first signal is used by the terminal to perform at least one of the following: acquire a second signal; perform measurement of the second cell; wake up the second cell; wherein the second signal is used by the terminal to camp on the second cell, or perform the service corresponding to the second cell, or perform measurement of the second cell, and the wireless access technologies corresponding to the first cell and the second cell are different.
[0264] In some embodiments, acquiring the second signal includes at least one of the following: acquiring the second signal from the first cell; acquiring the second signal from the second cell; acquiring the second signal from a third cell, wherein the third cell is indicated by the first cell and uses the same radio access technology as the first cell.
[0265] In some embodiments, the first signal or the second signal includes at least one of the following: synchronization signal, synchronization signal block SSB, physical broadcast channel PBCH, master information block MIB, system message, control signaling, demodulation reference signal DMRS, channel state information reference signal CSI-RS, tracking reference signal TRS, and positioning reference signal PRS.

[0267] In some embodiments, when the first signal is the synchronization signal or SSB and the second signal includes 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.
[0268] In some embodiments, when both the first signal and the second signal are 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.
[0269] In some embodiments, the first signal carries at least one of the following: target configuration information, which is used to indicate that the terminal requests to obtain the request configuration information of the second signal, and the target configuration information corresponds to the first cell, the second cell, or the third cell; and first indication information, which is used to indicate whether the second signal exists, signal resource configuration information, and target multiplexing pattern, wherein the signal resource configuration information is used to indicate the transmission resources for the transmission of the second signal, and the target multiplexing pattern is a multiplexing pattern between the first signal and the second signal.

[0272] In some embodiments, the method further includes: the network-side device sending a sixth indication information to the terminal; wherein the sixth indication information is used to indicate whether the second cell supports multiplexing the first signal.
[0273] It is understood that each implementation in this method embodiment 500 has the same or corresponding technical features as the aforementioned method embodiment 200. Therefore, each implementation in this method embodiment 500 can refer to the relevant description in the aforementioned method embodiment 200 and achieve the same or corresponding technical effects. To avoid repetition, it will not be described again here.
[0274] like Figure 6 The diagram shown is a flowchart of a communication method 600 provided in an exemplary embodiment of this application. This method 600 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the communication method 600 may include at least the following steps.
[0275] S610, the terminal receives target configuration information from the first cell.
[0276] The target configuration information is used to instruct the terminal to request configuration information for obtaining a second signal. The second signal is used for the terminal to camp on a second cell, or to perform services corresponding to the second cell, or to perform measurements in the second cell. The first cell and the second cell have different wireless access technologies.
[0277] In other words, in this embodiment, the terminal can reuse the target configuration information from the first cell to obtain the second signal for the terminal to camp on the second cell or for the terminal to perform services corresponding to the second cell or perform measurements of the second cell. This enables the terminal to reduce the transmission of request configuration information for requesting the second signal when camping on the second cell, enabling services corresponding to the second cell on the terminal, or performing measurements of the second cell, thereby reducing signaling overhead, saving network energy, increasing system throughput, and realizing DSS with a certain degree of coupling between different wireless access technology systems.
[0278] For example, assuming the first cell is a 5G cell and the second cell is a 6G cell, the terminal can request to obtain a second signal based on the target configuration information sent by the 5G cell, in order to camp on the 6G cell, enable the service corresponding to the 6G cell on the terminal, or perform measurements on the 6G cell. This reduces the amount of request configuration information sent in the 6G cell to request the second signal, reduces signaling overhead, saves network energy, increases system throughput, and realizes DSS with a certain degree of coupling between different wireless access technology systems.
[0279] Optionally, the target configuration information may correspond to the first cell, the second cell, or the third cell.
[0280] Optionally, the target configuration information can be transmitted in various ways, such as being carried in the first signal, like system messages, RRC signaling, MAC CE signaling, etc.
[0281] In some embodiments, when the terminal determines that the target configuration information corresponds to a target cell and that the second signal corresponding to the target cell can be used for the terminal to camp on the second cell, perform services corresponding to the second cell, or perform measurements on 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; wherein, the target cell includes the first cell or the third cell, the third cell is indicated by the first cell and has the same radio access technology as the first cell.
[0282] In some embodiments, the target configuration information is further used to instruct the service corresponding to the second cell to support the reuse of the second signal corresponding to the target cell. The relevant features regarding the target configuration information further instructing the service corresponding to the second cell to support the reuse of the second signal corresponding to the target cell can be found in the description of the second indication information in the aforementioned method embodiment 200, and will not be repeated here.
[0283] In some embodiments, the method further includes: the terminal requesting to obtain the second signal from the network-side device corresponding to the second cell or the first cell according to the target configuration information; wherein the target configuration information includes at least one of the following: third indication information for indicating the services supported by the second cell; fourth indication information for indicating the signal of the first cell that is being reused by the second cell or the services corresponding to the second cell; and fifth indication information for indicating the signal of the first cell that is being reused by the second cell or the services corresponding to the second cell.
[0284] In some embodiments, the method further includes: the terminal sending terminal capability information to the network-side device; wherein the terminal capability information is used to indicate at least one of the following: the terminal supports the second radio access technology to reuse 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; the terminal supports the service corresponding to the second cell.
[0285] It is understood that the various implementations in this method embodiment 600 (such as the type of the second signal, the target configuration information, the process by which the terminal requests the second signal based on the target configuration information, etc.) have the same or corresponding technical features as those in the aforementioned method embodiment 200. Therefore, the various implementations in this method embodiment 600 can refer to the relevant descriptions in the aforementioned method embodiment 200 and achieve the same or corresponding technical effects. To avoid repetition, they will not be described again here.
[0286] like Figure 7 The diagram shown is a flowchart of a communication method 700 provided in an exemplary embodiment of this application. This method 700 can be executed by, but is not limited to, a network-side device, specifically by hardware and / or software installed in the network-side device. In this embodiment, the communication method may include at least the following steps.
[0287] S710, the network-side device sends target configuration information to the terminal.
[0288] The network-side device corresponds to the first cell, and the target configuration information is used to instruct the terminal to request configuration information for obtaining the second signal. The second signal is used for the terminal to camp on the second cell or for the terminal to perform services corresponding to the second cell or to perform measurements in the second cell. The first cell and the second cell have different wireless access technologies.
[0289] In some embodiments, the target configuration information corresponds to a first cell, a second cell, or a third cell, wherein the third cell is indicated by the first cell and uses the same radio access technology as the first cell.
[0290] In some embodiments, when the target configuration information corresponds to the first cell or the third cell, the target configuration information is further used to indicate that the service corresponding to the second cell supports multiplexing the second signal corresponding to the target cell.
[0291] In some embodiments, when the target configuration information corresponds to the second cell, the target configuration information includes at least one of the following: third indication information for indicating the services supported by the second cell; fourth indication information for indicating the signal of the first cell that is being reused by the second cell or the service corresponding to the second cell; and fifth indication information for indicating the signal of the first cell that is being reused by the second cell or the service corresponding to the second cell.

[0293] It is understood that each implementation in this method embodiment 700 has the same or corresponding technical features as the aforementioned method embodiment 600.
