[0120] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems using configuration methods for other resources, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, LTE and NR).

[0121] In some cases, IoT devices are often powered by traditional batteries with limited lifespans, negatively impacting the user experience. The expected astronomical growth in the number of IoT devices, coupled with the massive scale of these devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. Eliminating traditional batteries significantly reduces device size and cost, paving the way for a variety of new applications.

[0122] In some implementations, various Low Power Wide Area (LPWA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), and Reduced Capability (RedCap), have been developed to meet the growing demands of various vertical sectors. These LPWA technologies offer low cost, low power consumption, and large-scale connectivity, meeting the requirements of many applications. However, many use cases and applications remain unaddressed. First, battery-powered devices are not suitable, such as in extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, and humid environments). Second, maintenance-free devices are required (e.g., devices without traditional batteries requiring replacement). Finally, ultra-low complexity, very small device size / form factor (e.g., mm thickness), and extended lifecycles are required. Ambient-powered IoT devices are promising technologies that can address these unmet needs. Ambient-powered IoT devices are IoT devices powered by energy harvesting, either without batteries or with limited energy storage capabilities (e.g., using capacitors). Energy is collected from radio waves, light, motion, heat, or any other suitable power source.

[0123] Energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as BLE, LoRa, NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only at the microwatt level, which is unable to drive these types of nodes to work. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve "Intelligent Connection of Everything". The methods that can be used include backscatter transmission (Backscatter Communications) technology.

[0124] In order to save energy in the network, network equipment has proposed SSB / SIB-less cells and cells that send SSBs and / or SIBs based on an on-demand mechanism (on demand).

[0125] In some embodiments, the SSB / SIB-less cell does not send SSBs and / or SIBs.

[0126] In some embodiments, the SSB / SIB-less cell does not send SSBs and / or SIBs.

[0127] In some embodiments, a cell that sends SSBs and / or SIBs based on an on-demand mechanism sends SSBs and / or SIBs according to network side requirements and / or terminal requirements.

[0128] The content broadcast by the cell in the NR system may include: MIB, SIB1 and other system information (OSI). The RMSI may include at least SIB1.

[0129] In some embodiments, the remaining minimum system information (RMSI) may include MIB and SIB1.

[0130] As shown in Figure 1B, the MIB may include configuration information for SIB1. For example, the MIB includes configuration information for scheduling resources. The scheduling resources may include Physical Downlink Control Channel (PDCCH) resources. The downlink control information (DCI) sent on the PUCCH resources is used to schedule SIB1. SIB1 can also be used to configure scheduling resources for OSI. In some embodiments, SIB1 may also include information required for accessing the corresponding cell and unified access control (UAC) parameters.

[0131] For example, SIB2 may include cell reselection information, which is mainly related to the serving cell.

[0132] For example, SIB3 may include reselection information related to the current serving frequency and the same-frequency neighboring cells.

[0133] For example, SIB4 may include reselection information related to other NR frequencies and inter-frequency neighboring cells.

[0134] For example, SIB5 may include Evolved-(Universal Mobile Telecommunications System, UMTS) Universal Terrestrial Radio Access (E-UTRA) frequency and E-UTRA neighbor cell related reselection information.

[0135] For example, SIB6 may include an Emergency Telecommunications Warning System (ETWS) primary notification.

[0136] For example, SIB7 may include ETWS secondary notification.

[0137] For example, SIB8 may include a Commercial Mobile Alert System (CMAS) warning notification.

[0138] For example, SIB9 may include information related to positioning system time and world time.

[0139] In some embodiments, SIB1 may include: cell selection configuration, cell access configuration, OSI scheduling configuration and / or cell common configuration, access control-related configuration parameters and / or cell capability-related configuration parameters.

[0140] In some embodiments, the RMSI control resource set (CORESET) is configured by the MIB. The RMSI CORESET has at least three resource location relationships with the SSB. The CORESET includes one or more PDCCH resources. The PDSCH can be used to transmit the SIB.

[0141] The terminal can obtain the resource location of the PDCCH based on the PBCH in the SSB, and further monitor the DCI based on the resource location of the PDCCH, and receive the RMSI according to the scheduling of the monitored DCI.

[0142] FIG1C shows diagrams of CORESET and SSB in different multiplexing modes of a communication system.

[0143] Figure 1 is used for a time division multiplexing (TDM) communication system. Figure 2 is used for a TDM and frequency division multiplexing (FDM) communication system. Figure 3 is used for an FDM communication system.

[0144] In some embodiments, for Network Energy Saving (NES), the system information sent by the network side is reduced.

[0145] In some embodiments, in addition to sending MIB and SIB1, the network device requests other SIBs on demand. That is, when the terminal needs other SIBs, the terminal sends a System Information (SI) request to the network device. After receiving the SI request, the network device determines whether to broadcast the corresponding SIB.

[0146] The SI request may include: an SI request based on message 1 (Message 1, Msg1) of the random access request and / or an SI request based on message 3 of the random access request.

[0147] In some embodiments, the SI request based on Msg1 may use reserved random access preamble (Preamble) and / or random access channel (RACH) resources.

[0148] In some embodiments, the SI request based on Msg3 does not require the reservation of RACH resources and random access preamble.

[0149] The SI request based on Msg3 can be defined as RRCSystemInfoRequest message (Msg3).

[0150] The terminal learns whether to use the SI request based on Msg1 or the SI request based on Msg3 by reading the system information.

[0151] If the base station provides the configuration information of the SI request (eg, si-Request-Config) in the system information (SIB1), the SI request based on Msg1 is used; otherwise, the SI request based on Msg3 is used.

[0152] After receiving the SI request, the base station may send an SI request confirmation to the terminal.

[0153] After receiving the SI request confirmation, the terminal receives SI in the current modification period. After receiving SI, the terminal knows that the modification period has ended or that SI has been received. If RACH fails during the SI request process, the subsequent behavior of the UE depends on the UE implementation.

[0154] FIG1D shows a method for information interaction between a network device and a terminal, which may include:

[0155] Network devices broadcast MIBs;

[0156] Network devices broadcast SIB1;

[0157] The terminal sends an SI request;

[0158] Network devices send system information.

[0159] In some embodiments, some terminals support network energy saving, while others do not. Terminals that support network energy saving may support different network energy saving mechanisms. For example, some terminals support SSB / SIB-less cells but do not support on-demand SSB and / or SIB. To enable terminals to access more types of cells and reduce the number of cells that can only be accessed in certain situations, an embodiment of the present disclosure provides a cell configuration method.

[0160] As shown in FIG2 , an embodiment of the present disclosure provides a method for transmitting DCI, which is performed by a communication system. The method may include:

[0161] S2101: The terminal sends first information to the network device.

[0162] In some embodiments, the terminal sends a radio resource control (RRC) message, a media access control (MAC) layer signaling, or uplink control information (UCI) containing the first information to the network device.

[0163] In some embodiments, the first information is used by the network device to determine the capabilities and / or expectations of the terminal.

[0164] In some embodiments, the first information is used by the network device to determine the cell type of the secondary cell supported and / or desired by the terminal.

[0165] In some embodiments, the first information may be used by the network device to directly or indirectly determine the capabilities of the terminal.

[0166] For example, the first information is capability information, which can be used to indicate the cell types supported by the terminal.

[0167] In some embodiments, the capability information may include, but is not limited to, at least one of the following:

[0168] First capability information, indicating whether the terminal supports cells of the first type and / or the second type;

[0169] second capability information, indicating whether the terminal supports cells of the first type on one or more frequency bands;

[0170] third capability information, indicating whether the terminal supports cells of the second type on one or more frequency bands;

[0171] Fourth capability information, indicating whether the terminal supports the first type of cell in one or more frequency band combinations; a frequency band combination (BC) may include one or more frequency bands;

[0172] fifth capability information, indicating whether the terminal supports the second type of cell in one or more frequency band combinations;

[0173] Sixth capability information, indicating whether the terminal supports the first type of cell on one or more feature sets; the feature set (FS) may include but is not limited to a combination of one or more of the following: a frequency band, a frequency band combination, a carrier component and / or a combination of one or more carriers;

[0174] Sixth capability information, indicating whether the terminal supports the second type of cell on one or more feature sets; the feature set (FS) may include but is not limited to a combination of one or more of the following: a frequency band, a frequency band combination, a carrier component and / or a combination of one or more carriers;

[0175] seventh capability information, indicating whether the terminal supports a first type of cell on one or more component carriers;

[0176] eighth capability information, indicating whether the terminal supports the second type of cell on one or more component carriers;

[0177] Ninth capability information, indicating whether the terminal supports the first type of cell within the same frequency range;

[0178] Tenth capability information, indicating whether the terminal supports the second type of cell within the same frequency range;

[0179] eleventh capability information, indicating whether the terminal supports the first type of cell within the heterofrequency range;

[0180] The twelfth capability information indicates whether the terminal supports a second type of cell within the heterofrequency range.

[0181] In some embodiments, the capability information is further used to indicate at least one of the following:

[0182] The cell types supported by the terminal on one or more frequency bands;

[0183] The cell types supported by the terminal on one or more frequency band combinations;

[0184] Feature set of cell types supported by the terminal; the feature set (FS) may include, but is not limited to, a combination of one or more of the following: frequency band, frequency band combination, carrier component and / or carrier;

[0185] The cell types supported by the terminal on one or more carriers;

[0186] The cell types supported by the terminal on one or more component carriers;

[0187] The cell types supported by the terminal on the same-frequency cell;

[0188] The cell types supported by the terminal on the inter-frequency cell.

[0189] For another example, the first information may be expectation information, which may be used to indicate the cell types supported by the terminal and the cell types it expects to access or reside in. In this case, the expectation information is equivalent to implicitly indicating the cell types supported by the terminal.

[0190] In some embodiments, the desired information is used to indicate the type of cell the terminal desires to access or reside in based on its operating state and / or energy state. For example, if the terminal is currently idle by the user, indicating a low processing and communication demand, the terminal can indicate to the network device through the desired information that it desires to operate in a cell of the first type, taking into account the terminal's capabilities.

[0191] As another example, if the terminal currently has business to transmit or is expected to have business data to transmit, it means that the terminal is in a working state with high communication requirements. Based on the terminal's capabilities, it can indicate to the network device through expected information that it expects to work in the second type of cell.

[0192] For example, if the current power consumption of the terminal is low, in order to save power consumption, the terminal can express its desire to work on the first type of cell, and expect to be a first type of cell and configure the first type of cell to facilitate the terminal to monitor the reference cell of SSB and / or SIB1, reduce the sending of the terminal's request information, and save the terminal's power consumption.

[0193] In some embodiments, the first information may include both capability information and expectation information. The capability information indicates the cell types supported by the terminal, and the expectation information indicates the cell type that the terminal expects to access or reside in. In this case, if the expectation information indicates that the cell type that the terminal expects to access and / or reside in is a cell type that the terminal does not support, the expectation information is invalid.

[0194] In some embodiments, the desired information may include: sorting information of the first type and the second type. For example, the terminal sorts the cell types it desires to operate in according to the degree of preference.

[0195] In some embodiments, the desired information may include: first type and second type priority information. For example, a higher priority indicates a higher preference of the terminal, and vice versa.

[0196] In short, the first information indicates the capabilities and / or expectations (or willingness) of the terminal.

[0197] In some embodiments, the first information may be user assistance information (UAI).

[0198] S2102: The network device configures the cell type of the first cell for the terminal.

[0199] In some embodiments, the network device may be an access network device.

[0200] In some embodiments, the network device configures the cell type of the first cell for the terminal.

[0201] In some embodiments, the cell types of the first cells configured by the network device for terminals with different capabilities may be the same or different.

[0202] In some embodiments, the cell type of the first cell at the terminal location and the actual cell type of the first cell may be the same or different.

[0203] In some embodiments, the network device configures the cell type of the first cell for the terminal according to the capabilities of the terminal and the capabilities of the first cell.

[0204] For example, in some embodiments, the network device configures the cell type of the first cell for the terminal to a cell type supported by both the terminal and the first cell according to the capabilities of the terminal and the capabilities of the first cell.

[0205] For example, for terminal A, only SSB / SIB-less cells are supported, but the first cell is actually an on-demand SSB / SIB cell. In this case, the network equipment of the first cell supports on-demand transmission of SSB / SIB, and in fact, it also supports SSB / SIB-less. Therefore, in order to enable terminal A to access the first cell, the network equipment can configure the first cell as an SSB / SIB-less cell.

[0206] In some embodiments, the first network device of the first cell configures the first cell type.

[0207] In some embodiments, the first network device of the second cell configures the first cell type.

[0208] In some embodiments, the second cell may be a neighboring cell of the first cell.

[0209] In some embodiments, for carrier aggregation and / or dual connectivity scenarios, the second cell may be a primary cell and the first cell may be a secondary cell; or, the second cell may be a primary secondary cell and the first cell may be a regular secondary cell.

[0210] In some embodiments, the first cell may be a serving cell or a camped cell of the terminal.

[0211] In some embodiments, the first cell may be a target cell or a candidate cell that the terminal needs to access or camp on.

[0212] In some embodiments, the cell type includes a first type and / or a second type.

[0213] In some embodiments, the first type of cell is a cell that does not transmit a synchronization signal broadcast block (SSB) and / or does not transmit a system information block (SIB). For example, an SSB / SIB-less cell may not transmit an SSB and / or SIB. For example, an SSB / SIB-less cell may not transmit an SSB and / or SIB1.

[0214] In some embodiments, the second type of cell is a cell that sends SSB and / or SIB on demand.

[0215] The on-demand transmission of SSB and / or SIB may include but is not limited to at least one of the following:

[0216] The cell sends SSB and / or SIB according to its own needs. For example, when the cell wants to establish downlink synchronization with the terminal or reestablish a downlink connection, it can be considered that a demand has been generated, and therefore the cell can actively broadcast SSB and / or SIB.

[0217] The cell sends SSB and / or SIB according to the needs of the terminal. For example, when the terminal needs to obtain SSB and / or SIB, it can send a request to the network device. In this way, the network device will know that the terminal needs to obtain SSB and / or SIB, and then determine whether to broadcast SIB.

[0218] In some embodiments, the terminal may request SSB and / or SIB from a cell that does not periodically send SIB by sending a wake-up signal (WUS).

[0219] In some embodiments, the cell type may further include: a third type. The third type of cell is a cell that periodically transmits SSBs and / or SIBs. The third type of cell periodically transmits SSBs and / or SIBs according to a semi-static configuration, a periodic configuration, and / or a dynamic configuration.

[0220] Assuming that the first cell is a cell that supports on-demand transmission of SSB and / or SIB, the first configuration is set to the first type or the second type according to the capability of the terminal, including at least one of the following:

[0221] The terminal has a first capability but does not have a second capability, and configures the cell type of the first cell to be the first type;

[0222] The terminal has the first capability and the second capability, and configures the cell type of the first cell to be the first type or the second type.

[0223] In some embodiments, the first capability is: the capability to camp on or access a cell of the first type.

[0224] In some embodiments, the second capability is a capability of camping on or accessing a cell of the second type.

[0225] In some embodiments, the terminal has the first capability and the second capability, and configuring the cell type of the first cell to the first type or the second type includes:

[0226] The terminal has the first capability and the second capability, and the cell type of the first cell is configured as the first type or the second type according to a requirement of the terminal.

[0227] The terminal has the first capability and the second capability, and configuring the cell type of the first cell to the first type or the second type according to a requirement of the terminal includes at least one of the following:

[0228] When the terminal has the first capability and the second capability and the terminal expects to access or camp on a cell of the first type, configuring the cell type of the first cell to be the first type;

[0229] The terminal has the first capability and the second capability and expects to access or camp on a cell of the second type, configuring the cell type of the first cell to the second type;

[0230] When the terminal supports the first type of cell and the second type of cell and the terminal expects to access or camp on the first type of cell and the second type of cell, the cell type of the first cell is configured as the first type or the second type according to network configuration.

[0231] In some embodiments, the network configuration may include but is not limited to local configuration of the network device, for example, configuration of the network device by a communication operator.

[0232] In some embodiments, when the terminal supports the first type of cell and supports the second type of cell and when the terminal expects to access or camp on the first type of cell or the second type of cell, the cell type of the first cell is configured as the first type or the second type according to network requirements.

[0233] For example, the load of the first cell that currently supports on-demand transmission of SSB and / or SIB is relatively heavy. For terminals that support on-demand transmission of SSB and / or SIB, the first configuration can also be set to the first type instead of the second type.

[0234] In some embodiments, if the first cell currently supports on-demand transmission of SSB and / or SIB, that is, the first cell supports acting as the first type and the second type, but may not support the third type. Therefore, in this case, if the terminal does not support on-demand transmission of SSB and / or SIB, does not support on-demand transmission of SSB / SIB1, and does not support SSB / SIB-less, that is, the terminal only supports periodic transmission of SSB and / or SIB, then considering network energy saving, the access and / or residence of such a terminal may be prohibited.

[0235] S2103: The network device sends a first configuration to the terminal.

[0236] In some embodiments, the network device sends the first configuration to the terminal according to the cell type of the first cell.

[0237] In some embodiments, the first network device sends the first configuration to the terminal according to the cell type of the first cell.

[0238] In some embodiments, the second network device sends the first configuration to the terminal according to the cell type of the first cell.

[0239] In some embodiments, the cell type of the first cell is a first type, and the first configuration includes at least one of the following:

[0240] A reference cell configuration, used to indicate a second cell referenced by the first cell;

[0241] The reference signal configuration is used by the terminal to determine the timing of the first cell.

[0242] For example, a first cell of the first type may not send an SSB and / or an SIB, and the terminal may discover the first cell based on an SSB sent by a reference cell on behalf of the cell of the first type.

[0243] For another example, a first cell of the first type may not send an SIB, and the terminal may receive, in the reference cell, an SIB sent by the reference cell instead of the cell of the first type.

[0244] In some embodiments, the reference signal configuration may be used to configure the terminal to obtain a reference signal for timing of the first cell. For example, the reference signal may include, but is not limited to, a tracking reference signal. Based on this timing, the terminal may maintain synchronization with the first cell.

[0245] In other embodiments, the reference signal configuration may not be limited to a reference signal used to configure the timing of the first cell. For example, the reference signal may also include but is not limited to a channel state information reference signal.

[0246] In some embodiments, the cell type of the first cell is the second type, and the first configuration includes: a request configuration, used by the terminal to request SSB and / or SIB from the first cell.

[0247] The request configuration may include configuration parameters such as resource configuration of the first request and / or the second request.

[0248] In some embodiments, the request may be an SI request based on Msg1 or an SI request based on Msg3.

[0249] In other embodiments, if the SI request is based on Msg1, the request configuration may include: information of a first random access preamble code, the first random access preamble code is used by the terminal to request SSB and / or SIB based on the random access request message.

[0250] In some embodiments, the information of the first random access preamble may include, but is not limited to, an index of the first random access preamble, or information such as a generation algorithm. For example, the length of the first random access strong preamble used to request an SSB and / or SIB may be different from the length of the second random access preamble used by the terminal when requesting service access, or the algorithm used may be different. In this case, the first random access preamble information may also be information indicating the length of the first random access preamble.

[0251] The first random access preamble is equivalent to a random access preamble reserved for triggering the first cell to send SSB and / or SIB.

[0252] In some embodiments, the number of first random access preamble codes may be one or more.

[0253] In some embodiments, when there are multiple first random access preambles, the SSB and SIB may correspond to different first random access preambles.

[0254] In some embodiments, when there are multiple first random access preambles, different SIBs may correspond to different first random access preambles.

[0255] S2104: The network device sends second information to the terminal.

[0256] In some embodiments, the second information is used to change the cell type of the first cell configured for the terminal.

[0257] In some embodiments, when the cell type of the first cell at the terminal location is changed or the actual cell type of the first cell is changed, the network device may send second information to the terminal.

[0258] For example, the first cell supports on-demand SSB / SIB and SSB / SIB-less. If the current cell type of the first cell is SSB / SIB-less and the first cell receives that its reference cell does not continue to replace the first cell to send SSB and / or SIB, the actual cell type of the first cell can be switched to the second type, and the network device can send a message to the terminal that the cell type of the second cell is changed from the first type to the second type.

[0259] In some embodiments, the second information includes at least one of the following:

[0260] A first instruction is used to instruct a type change of the first cell;

[0261] The second configuration is the configuration after the cell type of the first cell is changed.

[0262] Exemplarily, the cell type of the first cell configured for the terminal may be changed between a first type and a second type.

[0263] For example, the second information may indicate that the cell type of the first cell configured for the terminal may be changed from the first type to the second type.

[0264] For another example, the second information may indicate that the cell type of the first cell configured for the terminal can be changed from the second type to the first type.

[0265] In some embodiments, the first instruction may be any instruction sent by the network device. For example, the first instruction may be a layer (Layer, L) 1 instruction and / or an L2 instruction.

[0266] In some embodiments, the first instruction may be: downlink control information DCI.

[0267] In some embodiments, the DCI may indicate a change in the type of the first cell configured for the terminal through one or more bits.

[0268] In some embodiments, two bit values ​​of a bit in the first instruction represent change or no change, respectively.

[0269] In some embodiments, the first instruction is sent only when the cell type of the first cell configured for the terminal needs to be changed. When the terminal receives the first instruction, it believes that the cell type of the first cell configured for it by the network device has been changed.

[0270] In some embodiments, terminals are divided into two terminal groups based on whether they support on-demand transmission of SSBs and / or SIBs. One terminal group has all terminals that do not support on-demand transmission of SSBs and / or SIBs and support SSB / SIB1-less. Another terminal group has all terminals that support on-demand transmission of SSBs and / or SIBs and support SSB / SIB1-less.

[0271] In some embodiments, the DCI may be a group DCI, so that the network device of the first cell can send a group DCI to inform all terminals in a terminal group of the change in the cell type configured for them by the network device. For example, assuming that the cell type of the first cell configured for the terminal by the network device before the change is the first type, after receiving the group DCI indicating the change, it can be considered that the cell type of the first cell configured for the terminal by the network device has changed from the first type to the second type.

[0272] In some embodiments, the DCI may be dedicated DCI, which may indicate to a single terminal that the cell type of a first cell configured for the terminal by the network device has changed. Thus, assuming that the cell type of the first cell configured for the terminal by the network device was the first type before the change, upon receiving the dedicated DCI indicating the change, the network device may deem that the cell type of the first cell configured for the terminal has changed from the first type to the second type.

[0273] In some embodiments, the first instruction may be a first medium access control MAC element CE.

[0274] Exemplarily, the first MAC CE may include a bitmap, and the bitmap may indicate a cell type change of a cell using only one bit. For example, the first MAC CE may include a bitmap, and the bitmap may indicate a cell type change of a secondary cell of the terminal using only one bit.

[0275] For example, the first MAC CE may include a bitmap, where the bitmap uses only one bit to indicate the cell type of a cell. In this way, after receiving the current first MAC CE, the terminal compares it with the previously received first MAC CE. If the value of the indicator bit changes, it indicates that the cell type of the first cell configured for the terminal by the network device has changed.

[0276] Figure 1E is a schematic diagram of a first MAC CE. The first MAC CE shown in Figure 1E includes four octets (Ocelet, Oct), namely Oct1, Oct2, Oct3, and Oct4. Each octet includes 8 bits. One bit can indicate a cell type change or the changed cell type.

[0277] In some embodiments, the first MAC CE has a first logical channel identifier; the first logical channel identifier is different from a second logical channel identifier of the second MAC CE; and the second MAC CE is different from the first MAC CE.

[0278] Exemplarily, the second MAC CE may be a MAC CE indicating activation of the secondary cell.

[0279] As another example, the second MAC CE may be a MAC CE indicating activation or deactivation of semi-persistent scheduling resources.

[0280] In short, the second MAC CE may be various types of MAC CEs in related technologies.

[0281] In the embodiment of the present disclosure, in order to facilitate the terminal to distinguish MAC CEs with different functions, a dedicated first logical channel identifier is set for the first MAC CE. In this way, the terminal can determine whether the currently received MAC CE is the first MAC CE based on different logical channel identifiers.

[0282] In some embodiments, the MAC CE indicating the cell type change of the first cell configured by the network device for the terminal may be a MAC CE with remaining bits in the related art. In this case, the network device does not need to design a dedicated first logical channel identifier.

[0283] In some embodiments, the second configuration after the cell type of the first cell is changed may be sent to the terminal together with the first instruction, or the first instruction and the second configuration may be sent separately using different network messages.

[0284] In some other embodiments, when the network device sends the cell configuration of the first cell for the first time, it can send both cell configurations of the first cell, namely the first type and the second type, to the terminal. When the cell type of the first cell configured for the terminal by the network device is subsequently changed, the terminal can directly use the corresponding cell configuration according to the changed cell type. In this case, the network device does not need to temporarily send the cell configuration after the cell type is changed when the first cell type configured for the terminal is changed.

[0285] In some embodiments, the second information includes a second configuration.

[0286] Since the cell type of the first cell configured for the terminal changes, the cell configuration of the first cell also changes. In this case, the second information directly carries the second configuration of the cell type after the change of the first cell. The terminal will know the change of the cell type and the cell configuration after the change of the cell type at the same time.

[0287] When the second information includes the second configuration, the second information may or may not include the first instruction.

[0288] It is worth noting that if the cell type of the first cell has not changed, S2104 can be omitted. If the terminal capabilities can be determined based on the terminal type, or the access network device requests the terminal capabilities from the core network device based on the terminal identification information, S2101 can be omitted.

[0289] As shown in FIG3 , an embodiment of the present disclosure provides a cell configuration method, which is performed by a network device and may include:

[0290] S3101: Receive first information.

[0291] In some embodiments, the relevant description of the network device and the first information can be found in the corresponding embodiment of Figure 2.

[0292] S3102: Configure the cell type of the first cell for the terminal.

[0293] In some embodiments, optional implementations of S3102 may refer to S2102 of the corresponding embodiment of FIG. 2 .

[0294] S3103: Send the first configuration.

[0295] In some embodiments, optional implementations of S3103 may refer to S2103 in the corresponding embodiment of FIG. 2 .

[0296] S3104: Send the second information.

[0297] In some embodiments, optional implementations of S3104 may refer to S2104 of the corresponding embodiment of FIG. 2 .

[0298] It is worth noting that if the cell type of the first cell has not changed, S3104 can be omitted. If the terminal capabilities can be determined based on the terminal type, or the access network device requests the terminal capabilities from the core network device based on the terminal identification information, S3101 can be omitted.

[0299] As shown in FIG4 , an embodiment of the present disclosure provides a cell configuration method, which is executed by a terminal and may include:

[0300] S4101: Send the first message.

[0301] In some embodiments, optional implementations of S4101 may refer to S2103 of the corresponding embodiment of FIG. 2 .

[0302] S4102: Receive the first configuration.

[0303] In some embodiments, an optional implementation of the first configuration can be seen in the corresponding embodiment of FIG. 2 .

[0304] S4103: Receive the second information.

[0305] In some embodiments, optional implementations of the second information can refer to the corresponding embodiment of FIG. 2 .

[0306] It is worth noting that if the cell type of the first cell has not changed, S4103 can be omitted. If the terminal capabilities can be determined based on the terminal type, or the access network device requests the terminal capabilities from the core network device based on the terminal identification information, S4101 can be omitted.

[0307] The embodiments of the present invention provide that based on the auxiliary information provided by the terminal, the network side decides whether to configure the terminal with an SSB-less SCell or an on-demand SSB SCell, or depends on which mode the terminal chooses to work in, thereby increasing the flexibility of terminal implementation. At the same time, the network side also provides dynamic switching of the cell type configured for the terminal based on MAC CE or DCI to meet the flexibility of network operation.

[0308] First, the terminal may report its capability to support cell types. For example, in an on-demand SSB cell, the terminal may report its capability to support inter-band SSB-less and / or inter-band SSB-less.

[0309] The capability of a terminal may be per band, per terminal, per band combination (BC), or per feature set (FS).

[0310] For example, for terminals that only support inter-frequency SSB-less SCell capabilities and / or support intra-frequency SSB-less SCells, the network side can configure the on-demand SSB cell as an SSB-less cell. This operation of configuring an on-demand SSB cell as an SB-less cell can be referred to as an SSB-less operation. If a secondary cell of the terminal that is actually an on-demand SSB is configured as an SSB-less SCell, this operation of the network device can be referred to as an SSB-less SCell operation.

[0311] SSB-less SCell operation can be considered a fallback for on-demand SSB SCell. That is, an on-demand SSB SCell can be configured as an on-demand SSB SCell or an SSB-less SCell cell.

[0312] Auxiliary information indicating in an uplink RRC message whether the terminal prefers (i.e., expects or desires) to operate in an on-demand SSB SCell or an SSB-less SCell. For example, an enumerated type field is used to indicate the type of operation, where the enumerated value can be: on-demand SSB SCell operation, SSB-less SCell operation, or both. This auxiliary information can be the priority or ranking of the cell types that the terminal can or expects to operate in.

[0313] Before the terminal reports, the network configures whether the terminal can report the request or auxiliary information.

[0314] After the terminal reports, the network configures the terminal's cell type for a certain SCell to be: on-demand SSB SCell, SSB-less SCell, or both. If it is both, it depends on the working mode adopted by the terminal.

[0315] The network side configures the operating mode of the terminal target Scell ​​and the configuration parameters corresponding to the operating mode, such as on-demand SSB SCell operation and SSB-less SCell operation. Further RRC message notification gives the initial operating mode configured by the network side, which is on-demand SSB SCell operation or SSB-less SCell operation.

[0316] SSB-less SCell operation related parameters may include but are not limited to: reference cell configuration, and / or tracking reference signal (TRS) configuration, etc.

[0317] The on-demand SSB SCell related configuration parameters may include but are not limited to: configuration parameters of the requested SSB, such as the index of a specially designated random access preamble code (preamble index).

[0318] The network side can dynamically indicate through DCI or MAC CE whether the target SCell operates as an on-demand SSB SCell or an SSB-less SCell.

[0319] The format of the MAC CE may be: defining a new logical channel identifier (LCID) or an enhanced logical channel identifier (eLCID) for identifying the MAC CE.

[0320] The i-th bit in the bitmap corresponds to the i-th secondary cell. For example, Ci corresponds to the cell index of the secondary cell. The value of Ci, for example, a corresponding bit value of "0" indicates operation in an on-demand SSB SCell, while a comparison bit value of "1" indicates operation in an SSB-less SCell.

[0321] The benefit of this dynamic switching is that it increases network-side flexibility. It is also beneficial for future 5G and 6G dynamic spectrum sharing, dynamically shutting down SSB transmission and not allowing terminal requests to meet 6G data transmission and reception, avoiding 5G interference with 6G, and better realizing dynamic spectrum sharing between 5G and 6G.

[0322] The working mode of the secondary cell (SCell) is configured based on the terminal capability report, either on-demand SSB SCell or SSB-less SCell.

[0323] Based on the auxiliary information reported by the terminal or the preferred secondary cell (SCell) operation mode, the secondary cell (SCell) is configured to operate in on-demand SSB SCell or SSB-less SCell.

[0324] Dynamically switch the working mode based on DCI / MAC CE, on-demand SSB SCell or SSB-less SCell.
