Furthermore, multiple systems may be combined (e.g., a combination of LTE and NR, such as the systems defined in 6G).

[0139] On-demand SSB and / or SIB1 technology is one of the important candidate technologies. In the on-demand SSB and / or SIB1 technology, SSB and / or SIB1 are no longer sent periodically, but are sent according to the needs of the base station or terminal.

[0140] As shown in Figure 1B, a base station in an energy-saving state stops periodically transmitting SSBs and / or SIB1s, or transmits SSBs and / or SIB1s using a more sparse time-domain pattern. This energy-saving state may be a cell implementing the aforementioned NES mechanism, for example, a cell that is performing discontinuous transmission.

[0141] When a terminal has a SSB and / or SIB1 request, it sends a wake-up signal (WUS) to the base station. After receiving the WUS, the base station enters the normal state and sends SSB and / or SIB1. The normal state may be a non-energy-saving state.

[0142] In some embodiments, the base station stops sending SSBs and / or SIB1s after sending one or more SSB bursts or SS bursts, based on the network traffic load, the number of resident terminals, the traffic type, the time period, etc. When the base station stops sending SSBs and / or SIBs, it indicates that the base station has returned to a power-saving state.

[0143] To save network energy, a technology for reducing SSB and / or SIB1 in the time domain, namely SSB / SIB1-less technology, is proposed. In the SSB / SIB1-less technology, the SSB and / or SIB1 corresponding to the non-anchor cell of the terminal will be obtained through the anchor cell. The anchor cell can broadcast the SSB and / or SIB1 of multiple cells. For non-anchor cells (non-anchor cells), there is no need to periodically broadcast SSB and / or SIB1 information, thereby achieving the purpose of network energy saving.

[0144] In view of this, there may be one or more different types of cells, and the types of these cells can be distinguished according to the following situations: periodically sending the SSB of this cell; periodically sending the SIB1 of this cell; sending the SSB of this cell based on the on-demand mode; sending the SIB1 of this cell based on the on-demand mode; periodically sending the SSB of this cell and the SSB of other cells; periodically sending the SIB1 of this cell and the SIB1 of other cells; not sending the SSB of this cell; not sending the SIB1 of this cell; periodically sending the SSB of this cell and sending the SIB1 of this cell based on the on-demand mode, periodically sending the SIB1 of this cell and sending the SSB of this cell based on the on-demand mode, periodically sending the SSB of this cell and the SIB1 of other cells and sending the SSB of this cell based on the on-demand mode, periodically sending the SIB1 of this cell and the SIB1 of other cells and sending the SSB of this cell based on the on-demand mode. Periodically send the SIB1 of this cell and send the SSB of this cell based on the non-demand mode, periodically send the SSB of this cell and the SSB of other cells and send the SIB1 of this cell based on the non-demand mode, periodically send the SIB1 of this cell and the SIB1 of other cells and send the SSB of this cell based on the non-demand mode.

[0145] Exemplarily, the non-on-demand transmission may refer to the base station periodically transmitting the corresponding SSB or SIB1 based on semi-continuous or periodic configuration.

[0146] The above cells also affect the behavior of the terminal. For example, if the cell where the terminal is located sends the corresponding SIB1 of the cell based on the on-demand mode, during the period when the base station does not send SIB1, the terminal may need to send WUS on demand to trigger the corresponding SIB1 transmission. For example, if the cell where the terminal is located periodically sends the SIB1 of the cell and the SIB1 of other cells, the terminal will receive multiple cell SIB1s based on the configuration signaling, and reside in the cell corresponding to the SIB1 as needed based on the received SIB1 information.

[0147] In some embodiments, SSB and SIB1 are periodically sent at a determined time-frequency resource location according to a period predefined by the protocol and / or configured by the network side.

[0148] As shown in Figure 1C, an SSB occupies multiple consecutive OFDM symbols in the time domain. For example, an SSB may occupy four symbols. The SSB may include: Primary Synchronization Signals (PSS), Secondary Synchronization Signals (SSS), and PBCH information.

[0149] The New Radio (NR) system supports five SSB time domain transmission scenarios. The subcarrier spacing used to transmit SSB in scenarios A to E shown in Figure 1C is different, for example, some are 15kHz and some are 30kHz. Alternatively, the carrier frequency range (FR) for transmitting SSB in scenarios A to E shown in Figure 1C is different. In short, the time domain patterns of these scenarios depend on factors such as the subcarrier spacing (SCS) of SSB, the operating frequency, the communication standard of time division multiplexing and / or frequency division multiplexing, and so on.

[0150] Different SSB transmission conditions correspond to the number of SSBs in an SSB burst and the time domain resource positions occupied within the burst. The duration of an SSB burst is 5ms. Typically, the SSB transmission period is 20ms. Furthermore, the base station can configure the SSB transmission period and time domain pattern through the relevant information carried in SIB1. The maximum SSB transmission period is 160ms.

[0151] SIB1 is scheduled via DCI format 1-0 transmitted in the Type 0 Common Search Space (CSS) of Type 0. The synchronization signals and corresponding time-frequency resource locations associated with the Type-0 CSS can be indicated by the Master Information Block (MIB) or configured via SIB1 or RRC signaling. The transmission period and time-frequency resource locations depend on the SSB / SIB1 multiplexing pattern and the indication information carried in the DCI format 1-0 that schedules its transmission.

[0152] The base station needs to periodically transmit SIB1 so that terminals can obtain system information in a timely manner. In addition to the resource overhead incurred by SIB1 transmission itself, the control resource set (CORESET) used by the PDCCH transmission that schedules SIB1 transmission also occupies considerable time domain resources. SIB1 transmission can be illustrated in Figure 1D. Figure 1D shows different time domain configurations of two SSBs, SIB1, and CORESET#0.

[0153] Taking SIB1 as an example, which is scheduled by DCI format 1-0 transmitted in the common search space (Type0-(Common Serarch Space, CSS), Type0-CSS), and the SS related to Type-0 CSS and the corresponding time-frequency resource position are indicated by MIB, the corresponding SIB1 acquisition method is shown in Figure 1E.

[0154] In some embodiments, SSB may include two types of cell definition (Cell Defined, CD)-SSB and non-cell definition (Non Cell Defined, NCD)-SSB. CD-SSB is associated with SIB1, CD-SSB is associated with CORESET#0 corresponding to SIB1, and / or CD-SSB is associated with search space (SearchSpace, SS)#0 corresponding to SIB1. NCD-SSB is not associated with at least one of SIB1, CORESET#0 corresponding to SIB1, and SS#0 corresponding to SIB1. Ultimately, the network device schedules SIB1 through downlink control information (Downlink Control Inforamtion, DCI). For example, SIB1 is scheduled using DCI format 0-1. The DCI can be scrambled with System Information Radio Network Temporary Identity (SI-RNTI).

[0155] Currently, SSB and SIB1 need to be sent periodically. Even when the number of terminals assigned to a base station is small or the service load is extremely low, the base station still needs to periodically send SSB and SIB1 so that the terminals can complete time-frequency synchronization, automatic gain control (AGC) settings, secondary cell activation (Scell ​​activation), cell selection and / or cell reselection, and other related operations, as well as obtain system information. The periodic mandatory transmission of downlink signals will undoubtedly reduce the chances of the base station entering the sleep state, increase unnecessary energy consumption on the base station side, and increase the operator's operating costs.

[0156] Table 1 shows the time domain resource usage for SSB and SIB1 in different configuration / deployment scenarios. Considering that the time domain resource usage can reach up to 17.14%, in this scenario, the base station will not have the opportunity to enter a dormant state, which greatly limits the use of energy-saving technologies on the base station side and increases network operating costs.

[0184] In some embodiments of the first aspect, if a terminal in the first cell is unable to receive the first transmission, the terminal determines that the first cell is a second-category cell. Exemplarily, if the terminal in the first cell is unable to receive the first transmission and the failure to receive the first transmission is not due to a link failure of the terminal, the terminal determines that the first cell is a second-category cell.

[0185] In some embodiments of the first aspect, under the condition that the terminal determines that the first cell is a second type cell, if the terminal in the first cell cannot receive the first transmission, the terminal determines that the cell transmits the corresponding SSB / SIB1 based on the on demand mode.

[0327] In some embodiments, the third set may contain candidate values ​​for Kssb that are different from the candidate values ​​for Kssb contained in the fourth set.

[0328] For example, the third set may include even candidate values ​​for Kssb, and the fourth set may include odd candidate values ​​for Kssb.

[0329] For another example, the third set may include odd candidate values ​​of Kssb, and the fourth set may include even candidate values ​​of Kssb.

[0334] In some other embodiments, the candidate values ​​of Kssb included in the third set and the fourth set are determined according to a frequency range (FR) used by the first cell.

[0335] In some embodiments, if the frequency range used by the first cell is FRa, Kssb may be jointly indicated by PBCH information and MIB. For example, ssb-SubcarrierOffest may be jointly indicated by one bit of PBCH information and an indication bit of ssb-SubcarrierOffest in MIB.

[0336] In some embodiments, the frequency range used by the first cell is FRb, and Kssb may be indicated solely by the indication bit of ssb-SubcarrierOffest in the MIB.

[0337] In some embodiments, FRa and FRb are different. For example, Fra is located in Frequency Range 1 (FR1), and FRb is located in Frequency Range 2 (FR2).

[0340] The first cell is a first type cell, and it is determined that the PBCH information of the first cell has a second check code.

[0341] In some embodiments, different verification methods may correspond to different verification sequences, different verification algorithms, etc.

[0342] In this way, the type of the first cell can be implicitly indicated through different verification methods of the PBCH information.

[0343] In some embodiments, determining the type of the first cell according to a verification method of the PBCH information of the first cell includes at least one of the following:

[0344] A first check code used in the PBCH information of the first cell is generated based on a first check algorithm, and the first cell is determined to be a first-category cell;

[0345] The second check code used in the PBCH information of the first cell is generated based on a second check algorithm, and the first cell is determined to be a second type cell.

[0346] In some embodiments, the first check algorithm and the second check algorithm may be different cyclic redundancy check (CRC) algorithms.

[0347] Exemplarily, the verification method may refer to a method of calculating CRC in Downlink Physical-Layer processing.

[0348] Among them, the method of calculating CRC may include: g CRC24A (D), g CRC24B (D), g CRC24C (D), g CRC16 (D), g CRC11 (D) or g CRC11 (D), etc. The method of calculating CRC can also be called a check algorithm.

[0349] For example, the first verification algorithm may be g CRC24C (D).

[0350] For example, the second verification algorithm may be g CRC24A (D) or g CRC24B (D).

[0351] In some embodiments, the first check algorithm is a CRC check algorithm for PBCH information in the related art.

[0352] In some embodiments, the second verification algorithm is different from the first verification algorithm.

[0353] The above is merely an example of a verification method for the PBCH information of the first cell, and the specific implementation is not limited to the above example.

[0354] In some embodiments, according to the type of the first cell, setting the scheduling instruction for sending the first transmission in the first cell and / or the scheduling content of the scheduling instruction includes at least one of the following:

[0355] The first cell is a second type cell and does not send a scheduling instruction N times; N is a positive integer; exemplarily, the first cell is a second type cell and does not send a scheduling instruction N times consecutively at a reception opportunity of the first transmitted scheduling instruction; N is a positive integer;

[0356] The first cell is a second type cell and does not send a scheduling instruction for scheduling the first transmission for X times; X is a positive integer. For example, the first cell is a second type cell and does not send a scheduling instruction for scheduling the first transmission for X consecutive times at the reception opportunity of the scheduling instruction for the first transmission.

[0357] In some embodiments, the first cell is a second type cell, and the first cell does not schedule the first transmission during X times of receiving scheduling instructions capable of scheduling the first transmission; X is a positive integer.

[0358] Exemplarily, the scheduling instruction of the SIB may be downlink control information (DCI).

[0359] In some embodiments, if the first cell is a second type cell, the first cell fails to send DCI for N consecutive times or fails to send DCI for scheduling SIB for X consecutive times during the monitoring time of DCI capable of scheduling SIB.

[0360] In some embodiments, N and X may be any positive integers and may be configured or predefined by the network.

[0361] In some embodiments, N and X may be equal or unequal.

[0362] In some embodiments, the first cell is a second type cell and does not send scheduling instructions N times within the first time window.

[0363] In some embodiments, the first cell is a second type cell and does not send a scheduling instruction for scheduling the first transmission X times within the first time window.

[0364] The first time window may be determined by network signaling configuration or a predefined method, including but not limited to a protocol agreement.

[0365] Exemplarily, the starting position of the first time window is the period of the DCI of the first transmission currently scheduled by the terminal for blind detection.

[0366] Exemplarily, the starting position of the first time window is a period in which the terminal currently receives the first transmission based on the configuration.

[0367] In some embodiments, the first cell is a first type cell and determines to send the first transmission according to the configuration of the first transmission.

[0368] In some embodiments, the first cell is a second-category cell and determines to send the first transmission on demand. For example, the first cell is a second-category cell and determines to send the first transmission based on the first cell's own needs. For another example, the first cell is a second-category cell and determines to send the first transmission based on a triggering of a second transmission sent by a terminal.

[0369] In some embodiments, the first cell is a second type cell and determines not to send the first transmission.

[0370] S2102: The terminal determines the type of the first cell.

[0371] In some embodiments, terminals may be divided into two types, namely first type terminals and second type terminals.

[0372] For example, the first type of terminal may be a terminal that supports NES technology. The second type of terminal may be a terminal that does not support NES technology. The terminal that does not support NES technology may include but is not limited to a legacy terminal.

[0373] In some embodiments, S2102 may include: the first type terminal determining the type of the first cell.

[0374] In some embodiments, the second type terminal may skip the step of determining the type of the first cell.

[0375] In some embodiments, the second type terminal may execute S2102, and when determining that the first cell is a second type terminal, may re-camp on the first type cell through cell reselection and / or cell switching.

[0376] In some embodiments, the first cell is a first type cell or a second type cell. For the description of the first type cell and the second type cell, please refer to the description of step S2100.

[0377] In some embodiments, the manner in which the terminal determines the type of the first cell can be divided into two categories:

[0378] Category 1: Determine the type of the first cell according to a predefined method.

[0379] In some embodiments, the type of the first cell is determined according to a predefined method such as protocol agreement. Specifically, the terminal may determine the type of the first cell according to the cell attributes of the first cell and various types of cell attributes agreed upon in the protocol.

[0380] In some embodiments, the cell attributes may include: cell status, cell transmission mode, and / or sent downlink transmissions of the cell.

[0381] The cell status may include: whether the cell is in an energy-saving state. If the cell is in an energy-saving state, the first cell may be a second-category cell. If the cell is not in an energy-saving state, the first cell is a first-category cell. The energy-saving state may include a state in which SSBs and / or SIBs are not transmitted, or a state in which SSBs and / or SIBs are transmitted on demand.

[0382] In some embodiments, if the first cell sends SSB and / or SIB periodically, the first cell is a first-category cell; otherwise, it may be a second-category cell.

[0383] In some embodiments, if the first cell sends SSB on demand and / or SIB periodically, the first cell is a second type cell; otherwise, it may be a second type cell.

[0384] In some other embodiments, the network device determines the type of the first cell according to a frequency range used by the first cell, for example, the frequency band to which the first cell belongs.

[0385] At this time, the terminal does not need to receive information from the network device, and can determine whether the first cell is a first-category cell or a second-category cell according to a predefined method.

[0386] Category 2: The terminal determines the type of the first cell according to downlink transmission on the network side.

[0387] Exemplarily, the terminal determines the type of the first cell according to one or more downlink transmissions sent by the network device in S2101.

[0388] Also illustratively, the first type terminal determines the type of the first cell according to one or more downlink transmissions sent by the network device in S2101.

[0389] In the embodiment of the present disclosure, there are multiple ways to determine the type of the first cell based on downlink transmission on the network side. Several optional ways are provided below:

[0390] In some embodiments, the type of the first cell is determined based on the second transmitted configuration information. For example, the type of the first cell may be determined based on the purpose of the second transmitted configuration information.

[0391] In some embodiments, the second transmission is used to trigger the sending of the first transmission.

[0392] Since the second transmission is used to trigger the first transmission sent by the second type cell, if the terminal receives the configuration information of the second transmission for the first cell, it is equivalent to the network side implicitly indicating that the first cell is a second type cell.

[0393] For example, the terminal may receive the configuration information of the second transmission from the first cell or a neighboring cell of the first cell.

[0394] In some embodiments, the type of the first cell is determined according to whether the configuration information of the second transmission is used to trigger the first transmission of the first cell.

[0395] For example, if the second transmission configured by the configuration information does not act on the first cell but acts on other cells, it can be determined that the first cell is a first-category cell.

[0396] For example, the first cell is cell A and the second transmission is WUS. If the terminal receives the configuration information of the WUS of the first cell and the terminal can send WUS according to the configuration information of the WUS, and the WUS can trigger the first cell to send SSB and / or SI, then it can be confirmed that the first cell is a second-class cell, otherwise it can be a first-class cell.

[0397] In some embodiments, if the configuration information is used by the terminal to send the second transmission, the first cell is a second-category cell. Alternatively, if the configuration information is not used by the terminal to send the second transmission, the first cell is a first-category cell. That is, the type of a first cell can be distinguished based on whether the configuration information for the second transmission is configured for the cell.

[0398] In some embodiments, if the terminal receives configuration information and determines that the configuration information is used to send a second transmission that triggers the first cell to send a first transmission, the terminal determines that the first cell is a second type cell.

[0399] In some embodiments, if the terminal does not receive any configuration information corresponding to the second transmission used to trigger the first cell to send the first transmission, and / or the terminal can receive the first transmission based on the corresponding first transmission configuration information, the terminal determines that the first cell is a first type cell.

[0400] In some embodiments, the second transmission may be referred to as a wake-up signal (WUS). The configuration information of the second transmission is the configuration information of the WUS.

[0401] In some embodiments, if the configuration information is used to send a WUS that triggers the first cell to send a first transmission, the first cell is a second-category cell. If the configuration information is not used to send a WUS that triggers the first cell to send a first transmission, the first cell is a first-category cell. That is, the type of the first cell can be distinguished based on the WUS configuration information.

[0402] In some embodiments, if the terminal receives configuration information and determines that the configuration information is used to send a WUS that triggers the first cell to send a first transmission, the terminal determines that the first cell is a second type cell.

[0403] In some embodiments, if the terminal does not receive any configuration information corresponding to the WUS used to trigger the first cell to send the first transmission, and / or the terminal can receive the first transmission based on the corresponding first transmission configuration information, the terminal determines that the first cell is a first type cell.

[0404] Here, any configuration information of the second transmission does not correspond to the first cell, that is, any second transmission is not used to trigger the first cell to send the first transmission, which means that the first cell is a first type cell rather than a second type cell.

[0405] The cell receiving the second transmission may be a corresponding second-category cell or a cell associated with the second-category cell. For example, the cell associated with the second-category cell may include: a neighboring cell of the second-category cell, a primary cell associated with the second-category cell, or a secondary cell associated with the second-category cell.

[0406] In some embodiments, the cell receiving the second transmission may be a cell of the first type. After receiving the second transmission, the cell of the first type notifies the cell of the second type of trigger information corresponding to the second transmission through information exchange.

[0407] In some embodiments, the terminal determines the cell identity (ID) corresponding to the first cell based on the SSB of the first cell, and compares it with the cell ID applied to the second transmitted configuration information to determine whether the second transmitted configuration information corresponds to the first cell. If the second transmitted configuration information corresponds to the first cell, it can be confirmed that the first cell is a second type cell; otherwise, it can be determined that the first cell is a first type cell.

[0408] In some embodiments, the configuration information of the second transmission is carried in the cell configuration of the first cell, or the configuration information of the second transmission is carried in the cell configuration of the third cell.

[0409] The second transmitted configuration information may be carried in the cell configuration of the first cell itself or in the cell configuration of other cells.

[0410] In some embodiments, the third cell is a primary cell of the terminal and the first cell is a secondary cell of the terminal.

[0411] In some embodiments, the third cell is a secondary cell of the terminal and the first cell is a primary cell of the terminal.

[0412] For example, the third cell may be the primary cell of the terminal. The cell configuration of the primary cell may carry the second transmission configuration information of one or more secondary cells of the terminal. In this way, the corresponding secondary cell is a second type cell.

[0413] In some embodiments, the configuration information of the second transmission is carried in the cell configuration of the first cell.

[0414] For example, if the first cell is a secondary cell, the cell configuration may include but is not limited to a secondary cell configuration (ScellConfig).

[0415] For another example, if the first cell is a serving cell, the cell configuration may include but is not limited to a serving cell configuration (servingCellConfig).

[0416] In some embodiments, the type of the first cell is determined according to the cell configuration of the first cell.

[0417] In some embodiments, the cell configuration of the first cell may explicitly or implicitly indicate the type of the first cell.

[0418] One or more explicit indication bits are carried in the cell configuration of the first cell, indicating the type of the first cell.

[0419] In some other embodiments, whether the cell configuration carries the second transmission configuration is used to implicitly indicate whether the first cell is a second type cell.

[0420] In some embodiments, whether the cell configuration of the first cell includes a state of the first indication field is used to implicitly indicate the type of the first cell.

[0421] In some embodiments, the cell configuration of the first cell includes a first indication field, determining that the first cell is a first type cell, and the cell configuration of the first cell does not include the first indication field, determining that the first cell is a second type cell.

[0422] In other embodiments, the cell configuration of the first cell includes the first indicator field, and the first cell is determined to be a second-category cell, and the cell configuration of the first cell does not include the first indicator field, and the first cell is determined to be a first-category cell.

[0423] In some embodiments, the indication content of the second indication field included in the cell configuration of the first cell determines that the first cell is a first type cell or a second type cell.

[0424] Exemplarily, a second indication field is added to the cell configuration of the first cell, and different indication contents of the second indication field correspond to whether the first cell is a first-category cell or a second-category cell.

[0425] In some embodiments, the first indicator field has a first value, indicating that the first cell is a first-category cell. The first indicator field has a second value, indicating that the first cell is a second-category cell.

[0426] In some embodiments, the cell configuration includes: a secondary cell ScellConfig configuration.

[0427] In some embodiments, the type of the first cell is determined based on a master information block (MIB) of the first cell.

[0428] In some embodiments, the type of the first cell is determined based on the value of one or more indication bits of the spare bits, synchronization signal broadcast block-subcarrier spacing offset (ssb-SubcarrierOffest), demodulation reference signal type A position (DRMS-typeA-Position), downlink control channel SIB1 configuration (pdcch-ConfigSIB1), cell barring indication (CellBarred), intraFreqReselections, and common subcarrier spacing (subcarrierSpacingCommon) in the MIB of the first cell.

[0429] In some embodiments, the MIB may include one or more indication bits. One approach is to multiplex indication bits indicating other information to indicate the type of the first cell. Another approach is to use idle bits in the MIB to indicate the type of the first cell.

[0430] In some embodiments, the type of the first cell is determined based on the value of a spare bit in the MIB of the first cell. Exemplarily, the spare bit may be any bit in the MIB that has no specific indication meaning.

[0431] In some embodiments: the type of the first cell is determined according to the value of the synchronization signal broadcast block-subcarrier spacing offset ssb-SubcarrierOffest indication bit in the MIB of the first cell.

[0432] Exemplarily, the ssb-SubcarrierOffest indication bit in the MIB not only indicates the value of an ssb-SubcarrierOffest, but also corresponds the value to the type of the first cell. In this way, when the terminal receives this MIB, it can know the value of the ssb-SubcarrierOffest on the one hand, and the type of the first cell on the other hand based on the ssb-SubcarrierOffest indication bit.

[0433] In some embodiments: the type of the first cell is determined according to the value of the system frame number SFN indication bit in the MIB of the first cell.

[0434] Exemplarily, the type of the first cell may be indicated by the correspondence between the SFN indicated by the MIB and the type of the first cell.

[0435] In some embodiments: the type of the first cell is determined according to the value of the demodulation reference signal DRMS-Type A position indication bit in the MIB of the first cell.

[0436] Exemplarily, a correspondence between the DRMS ​​type A indication bit and value and the type of the first cell may be established, thereby implementing type indication of the first cell.

[0437] In some embodiments: the type of the first cell is determined according to the value of a cell barred indication bit in the MIB of the first cell.

[0438] Exemplarily, the cell barred indication bit may directly or indirectly indicate the type of the first cell.

[0439] In some embodiments: the type of the first cell is determined according to the value of the subcarrier spacing subcarrierSpacingCommon indication bit in the MIB of the first cell.

[0440] Exemplarily, the common subcarrier spacing subcarrierSpacingCommon indication bit may directly or indirectly indicate the type of the first cell.

[0441] In some embodiments, the value of at least one indicator bit in the MIB of the first cell is within a first set, indicating that the first cell is a first-category cell. In some embodiments, the value of at least one indicator bit in the MIB of the first cell is within a second set, indicating that the first cell is a second-category cell.

[0442] Exemplarily, determining the type of the first cell according to the value of the synchronization signal broadcast block-subcarrier spacing offset ssb-SubcarrierOffest indication bit in the MIB of the first cell includes:

[0443] The value of the ssb-SubcarrierOffest indication bit in the MIB of the first cell is within the first set, and the first cell is determined to be a first-category cell;

[0444] The value of the ssb-SubcarrierOffest indication bit in the MIB of the first cell is within the second set, and the first cell is determined to be a second type cell.

[0445] In some embodiments, both the first set and the second set may include one or more alternative ssb-SubcarrierOffest values. The first set corresponds to a first type of cell, and the second set corresponds to a second type of cell. In this case, the terminal may determine the type of the first cell based on the set of bit values ​​indicated by the ssb-SubcarrierOffest indicator bit.

[0446] In some embodiments, the values ​​of the first set and the second set may be predefined by network configuration or protocol agreement.

[0447] In some embodiments, the values ​​in the first set and the second set may be configured by the network device, or may be predefined by protocol agreement or the like.

[0448] Exemplarily, the values ​​of the first set are even numbers, and the values ​​of the second set are odd numbers. Exemplarily, the values ​​of the first set are odd numbers, and the values ​​of the second set are even numbers. Furthermore, exemplarily, the first set includes a value range that is different from the value range of the second set. For example, the values ​​of the first set may all be smaller than the values ​​of the second set, or the values ​​of the first set may all be larger than the values ​​of the second set.

[0449] Exemplarily, the values ​​of the second set correspond to the reserved state, and the values ​​of the first set correspond to states other than the reserved state. Exemplarily, taking CORESET#0 corresponding to SIB1 as determined based on Table 2, the first set corresponds to indexes 0, 1, 2, ..., 13 in Table 2, and the second set corresponds to indexes 14 and 15 in Table 2.

[0450] If the bit corresponding to pdcch-ConfigSIB1 indicates index=14 in the table, the cell corresponding to the SSB where the MIB carrying pdcch-ConfigSIB1 is located belongs to the second type of cell.

[0451] In some embodiments, the value of the ssb-SubcarrierOffest indication bit in the MIB includes the last bit of the ssb-SubcarrierOffest indication bit in the MIB.

[0452] In some embodiments, the type of the first cell is determined by the value of the downlink control channel SIB1 configuration (pdcch-ConfigSIB1) indication bit in the MIB of the first cell.

[0453] In some embodiments, the value of the cell barred indication bit in the MIB of the first cell is determined according to the type of the first cell.

[0454] In some embodiments: the type of the first cell is determined according to the value of the intraFreqReselections indication bit in the MIB of the first cell.

[0455] Exemplarily, the type of the first cell may be directly or indirectly indicated by the intraFreqReselections indication bit.

[0456] In some embodiments, the type of the first cell is determined based on physical broadcast channel (PBCH) information of the first cell.

[0457] In some embodiments, the type of the first cell is determined based on reserved bits of the PBCH information of the first cell.

[0458] In some embodiments, the PBCH information indicates It is the first value, and the reserved bit is the first bit.

[0459] In some embodiments, the Equal to the maximum number of candidate synchronization signal broadcast blocks SSB in a half frame.

[0460] In some embodiments, the Equal to the maximum number of SSBs contained in an SSB burst.

[0461] In some embodiments, the first value may be 10.

[0462] In some embodiments, the PBCH information indicates For the second value, the reserved bits are the second bit and / or the third bit.

[0463] In some embodiments, the second value may be less than or equal to 8. In some embodiments, the first bit may include but is not limited to

[0464] In some embodiments, the second bit may be

[0465] In some embodiments, the cell may broadcast an SSB, which will include a primary synchronization signal, a secondary synchronization signal, and PBCH information.

[0466] The PBCH information may be any information carried on the PBCH. In the embodiment of the present disclosure, the first cell may indicate the type of the first cell through the PBCH information.

[0467] In some embodiments, the type of the cell is determined based on the value of Kssb.

[0468] When Kssb belongs to the first set, the cell associated with SSB is a first type cell.

[0469] When Kssb belongs to the second set, the cell associated with SSB is a second type of cell.

[0470] The first set may be determined based on signaling or a predefined manner.

[0471] In some embodiments, in the FR1 scenario, the second set is a Kssb greater than or equal to 24, and in the FR2 scenario, the second set is a Kssb greater than or equal to 12.

[0472] In some embodiments, in the FR1 scenario, the first set is a Kssb less than 24, and in the FR2 scenario, the second set is a Kssb less than 12.

[0473] In some embodiments, the second set is Kssb with an even value, and the first set is Kssb with an odd value.

[0474] In some embodiments, the second set is Kssb with odd values, and the first set is Kssb with even values.

[0475] In some embodiments, in the FR1 scenario, the first set is an even number Kssb less than 24, and in the FR2 scenario, the second set is an even number Kssb less than 12.

[0476] In some embodiments, in the FR1 scenario, the first set is an odd number Kssb less than 24, and in the FR2 scenario, the second set is an odd number Kssb less than 12.

[0477] In some embodiments, in the FR1 scenario, the first set is an odd number Kssb less than 24, and in the FR2 scenario, the second set is an odd number Kssb less than 12.

[0478] In some embodiments, in the FR1 scenario, the first set is an even number Kssb less than 24, and in the FR2 scenario, the second set is an even number Kssb less than 12.

[0479] In some embodiments, when the first cell belongs to the second type of cell, the SSB of the corresponding cell may be a cell that is not associated with CORESET#0 or Remaining minimum system information (RMSI) or SIB1, that is, in the FR1 scenario, the corresponding Kssb is greater than or equal to 24, and in the FR2 scenario, Kssb is greater than or equal to 12.

[0480] In some embodiments, the second set is Kssb equal to 30 in FR1 scenario, and the second set is Kssb equal to 14 in FR2 scenario.

[0481] In some embodiments, in the FR1 scenario, the first set is Kssb not equal to 30, and in the FR2 scenario, the second set is Kssb not equal to 14.

[0482] In some embodiments, the terminal determines Kssb based on network signaling, and determines the subcarrier spacing (kSSB-offset) based on Kssb.

[0483] In some embodiments, the network signaling may be MIB, or MIB and PBCH information.

[0484] In some embodiments, the kSSB-offset is equal to the SSB lowest subcarrier multiplied by N CRB The offset of the lowest subcarrier, the N CRB It is the lowest CRB that has frequency domain intersection with CRB.

[0485] In some embodiments, Kssb is less than a specified value, for example, less than 24 for FR1, or less than 12 for FR2, and the subcarrier spacing can be considered equal to kSSB-offset=Kssb.

[0486] In some embodiments, Kssb is greater than or equal to a specified value, and the subcarrier spacing kSSB-offset can be determined based on Kssb.

[0487] Exemplarily, the designated value may include but is not limited to any value greater than or equal to 24, for example, 30. The network signaling may include but is not limited to: MIB, PBCH information, SIB and other signaling sent by the network side.

[0488] Exemplarily, the designated value may include but is not limited to any value greater than or equal to 12, for example, 14. The network signaling may include but is not limited to: MIB, PBCH information, SIB and other signaling sent by the network side.

[0489] Exemplarily, under the condition that Kssb is greater than or equal to a specified value, the terminal determines the subcarrier spacing kSSB-offset based on predefined rules, and the predefined rules include but are not limited to: kSSB-offset=Kssb-N1; kSSB-offset=Kssb mod M1

[0490] The N1 and M1 are determined based on signaling instructions or predefined rules.

[0491] Exemplarily, N1 is equal to 9 or 10;

[0492] Exemplarily, M1 is equal to 24 (corresponding to FR1), and M1 is equal to 12 (corresponding to FR1 or corresponding to FR2).

[0493] For example, for a terminal that supports network energy saving, after receiving an SSB and reading the corresponding Kssb=30, it can determine based on signaling that the cell is a second-class cell, and determine the frequency domain position of the CRB based on Kssb. The specific method is as follows:

[0494] The terminal determines the lowest subcarrier of SSB and N based on Kssb-offset CRB The offset of the lowest subcarrier, N CRB The lowest CRB that has frequency domain intersection with the CRB. Kssb-offset = Kssb-9, or Kssb-offset = Kssb mod 24. This can be applied to scenarios where Kssb = 30 or other Kssb values.

[0495] Exemplarily, for a terminal that supports network energy saving, under the condition that the cell is determined to be a second-category cell based on signaling, the corresponding pdcch-ConfigSIB1 can be read to determine the corresponding SearchSpace#0 or CORESET#0.

[0496] In some embodiments,

[0497] The type of the first cell is determined according to the MIB and PBCH information of the first cell.

[0498] In this method, the MIB and PBCH information of the first cell are combined to jointly determine the type of the first cell. Exemplarily, the type of the first cell is determined by combining at least one indicator bit of the MIB and PBCH information.

[0499] In some embodiments, the first cell is determined to be a second type cell based on the value of the subcarrier offset Kssb jointly indicated by the MIB and the PBCH.

[0500] Exemplarily, the maximum value indicated by the indicator bit of Kssb is small, and only the indicator bit of MIB can be used. When the maximum value indicated by the indicator bit of Kssb is large, the indicator bits of MIB and PBCH information can be occupied simultaneously. In this case, Kssb indicated by both MIB and PBCH information can be mapped to the type of the first cell. Therefore, determining the type of the first cell based on Kssb jointly indicated by MIB and PBCH information is an optional method for MIB and PBCH information to jointly indicate the type of the first cell.

[0501] In some embodiments, the first cell is determined to be a second-category cell based on the value of the subcarrier offset Kssb jointly indicated by the MIB and PBCH, including at least one of the following: the value of the subcarrier offset Kssb jointly indicated by the MIB and PBCH is within the third set, and the first cell is determined to be a first-category cell; the value of the subcarrier offset Kssb jointly indicated by the MIB and PBCH is within the fourth set, and the first cell is determined to be a second-category cell.

[0502] In some embodiments, MIB is transmitted based on PBCH. According to the value of the subcarrier offset Kssb jointly indicated by MIB and PBCH, it can be understood that joint indication is based on ssb-SubcarrierOffest in MIB and other bits in PBCH.

[0503] In some embodiments, the third set may contain candidate values ​​for Kssb that are different from the candidate values ​​for Kssb contained in the fourth set.

[0504] For example, the third set may include even candidate values ​​for Kssb, and the fourth set may include odd candidate values ​​for Kssb.

[0505] For another example, the third set may include odd candidate values ​​of Kssb, and the fourth set may include even candidate values ​​of Kssb.

[0506] For example, the candidate values ​​of Kssb included in the third set are all greater than the candidate values ​​of Kssb included in the fourth set.

[0507] For another example, the candidate values ​​of Kssb included in the fourth set are all greater than the candidate values ​​of Kssb included in the third set.

[0508] In some embodiments, the candidate values ​​of Kssb included in the third set and the fourth set are predefined, for example, predefined by a protocol.

[0509] In other embodiments, the alternative values ​​of Kssb included in the third set and the fourth set are configured by the network device.

[0510] In some other embodiments, the candidate values ​​of Kssb included in the third set and the fourth set are determined according to a frequency range (FR) used by the first cell.

[0511] In some embodiments, the type of the first cell is determined based on a verification method of the PBCH information of the first cell.

[0512] In some embodiments, different verification methods may correspond to different verification sequences, different verification algorithms, etc.

[0513] In this way, the type of the first cell can be implicitly indicated through different verification methods of the PBCH information.

[0514] In some embodiments, determining the type of the first cell according to a verification method of the PBCH information of the first cell includes at least one of the following: successfully verifying the PBCH information of the first cell using a first verification algorithm, thereby determining that the first cell is a cell of the first type;

[0515] The PBCH information of the first cell is successfully verified using a second verification code algorithm, and the first cell is determined to be a cell of the second type. In some embodiments, the first verification algorithm and the second verification algorithm can both be cyclic redundancy check (CRC) verification algorithms.

[0516] In some embodiments, the type of the first cell is determined according to a reception condition of the first transmission by the terminal in the first cell.

[0517] In some embodiments, the terminal may pre-determine the first cell as a first-type cell, and thus periodically monitor the first transmission; and subsequently determine the type of the first cell based on a reception status of the first transmission.

[0518] For example, after camping on the first cell, the terminal can first regard the first cell as a first-class cell and monitor the first transmission for multiple periods. If the first transmission is not received, the first cell can be considered as a second-class cell. Otherwise, the first cell can be considered as a first-class cell.

[0519] For example, the terminal may camp on the first cell before the first cell is converted into the second type cell. For example, the first cell may be changed from the first type cell to the second type cell through state switching.

[0520] For another example, the first cell may be a cell that sends SSB but does not send SIB or sends SIB on demand. In this case, the terminal can normally reside on the first cell, but the type of the first cell needs to be further determined.

[0521] For another example, the terminal may reside on the first cell by replacing the SSB sent by the first cell with other cells. In this way, after the first terminal resides on the first cell, it is necessary to further determine the type of the first cell.

[0522] In some embodiments, the multiple periods may be periods continuously distributed in the time domain, or specified specific periods.

[0523] In some embodiments, if the terminal fails to receive the first transmission M times in a row at a reception opportunity of the first transmission, the terminal determines that the first cell is a second type cell. In some embodiments, M is a positive integer. Specifically, M is equal to 1, 2, or 3.

[0524] In some embodiments, the value of M may be configured by the network or determined based on a predefined method.

[0525] In some embodiments, the terminal failing to receive the first transmission M times in a row at the reception timing of the SSB may include: the terminal failing to receive the SSB at M consecutive time domain transmission positions of the SSB according to the configuration of the SSB.

[0526] In some embodiments, the terminal failing to receive the first transmission M times consecutively at a SIB reception opportunity may include: the terminal failing to receive the SSB at M consecutive time-domain transmission positions of the SIB according to the configuration of the SIB. Figure 1D illustrates a time-domain configuration of an SSB and / or SIB, showing that an SSB and SIB may have one or more reception opportunities in a time slot.

[0527] For example, after the terminal resides in the first cell, if the terminal fails to monitor the SSB at M consecutive SSB reception opportunities, the first cell can be considered as a second type cell.

[0528] For another example, after the terminal camps on the first cell, if the terminal does not receive SIB1 in M ​​consecutive SIB1 reception opportunities, the first cell may be considered as a second type cell.

[0529] In some embodiments, the reception opportunity may include, but is not limited to, a reception time window determined based on the configuration of the first transmission. For example, a first time window is configured for SIB1. One first time window may be a reception opportunity for SIB1. A second time window is configured for SSB. One second time window may be a reception opportunity for SSB.

[0530] In some embodiments,

[0531] The type of the first cell is determined according to a reception status of the first transmitted scheduling instruction by the terminal in the first cell.

[0532] In some embodiments, if the terminal fails to receive the scheduling instruction N times in a row at the reception timing of the first transmitted scheduling instruction, the terminal determines that the first cell is a second type cell; N is a positive integer.

[0533] In some embodiments, if the terminal receives a scheduling instruction that can schedule the first transmission for X consecutive times but fails to schedule the first transmission, the terminal determines that the first cell is a second-category cell; X is a positive integer.

[0534] Exemplarily, the scheduling instruction of the SIB may be downlink control information (DCI).

[0535] In some embodiments, if the terminal fails to receive DCI for N consecutive times during the monitoring time of the DCI scheduling SIB, it means that the first cell has no need to schedule SIB transmission, which means that it is very likely that the first cell is a second type cell.

[0536] In other embodiments, the terminal receives DCI that can schedule SIB during the listening time of DCI scheduling SIB, but the DCI does not schedule SIB for X consecutive times, which means that the first cell may currently be sending SIB on demand, and therefore it is very likely that the first cell is a second type cell.

[0537] In some embodiments, N and X may be any positive integers and may be configured or predefined by the network.

[0538] In some embodiments, N and X may be equal or unequal.

[0539] In some embodiments, if the terminal does not monitor the DCI scheduling SIB within a continuous period after camping on the first cell, it means that the first cell does not send SIB, and the first cell can be considered as a second-class cell; otherwise, the first cell can be considered as a first-class cell.

[0540] In some embodiments, the terminal has previously received the SIB sent by the first cell, but has not received either the SIB or the DCI scheduling the SIB for a long period of time starting from a certain period of time. It is possible that the first cell has changed its cell settings from a first type cell to a second type cell.

[0541] In some embodiments, the terminal determines the state of the cell based on the following method: If the terminal does not receive the corresponding first transmission within the first time window, the terminal determines that the cell is a first sub-type cell or a second sub-type cell in the second type of cell.

[0542] In some embodiments, the first time window starts with the blind detection period of the current first transmission where the terminal is located, and N consecutive blind detection periods of the first transmission.

[0543] In some embodiments, the first time window starts with the current first transmission period of the terminal and includes N consecutive first transmission periods.

[0544] In some embodiments, the first sub-category cell is an on-demand cell, and the second sub-category cell is a cell that is prohibited from terminal access.

[0545] In some embodiments, the terminal stores state information of the cell.

[0546] In some embodiments, after receiving the second transmission configuration information corresponding to the cell, the cell is determined to be a first sub-category cell; otherwise, the cell is determined to be a second sub-category cell.

[0547] In some embodiments, the type of the first cell is determined based on a reception condition of whether a first transmission of the first cell is received from a second cell.

[0548] In some embodiments, the terminal does not receive the first transmission of the first cell from the second cell and determines that the first cell is a second type cell; the terminal receives the first transmission of the first cell from the second cell and determines that the first cell is a second type cell.

[0549] In some embodiments, some cells of the first category may replace cells of the second category in sending the first transmission.

[0550] In some embodiments, if the terminal receives the first transmission of the first cell from the second cell, it means that the first cell may not send the first transmission itself or sends the first transmission on demand, that is, the first cell is a second type cell.

[0551] In some embodiments, for example, the first cell is a primary cell of the terminal, and the second cell is a secondary cell of the terminal. If the terminal monitors the SSB and / or SIB1 of a secondary cell on the primary cell, the corresponding secondary cell may be considered to be a second type cell.

[0552] Exemplarily, the first transmission sent by the second cell instead of the first cell may carry the cell identifier and / or cell index of the second cell. In this way, when the terminal receives the first transmission sent by the second cell, it knows to which cell the corresponding first transmission belongs.

[0553] In some embodiments of the first aspect, a terminal in a first cell receives the first transmission based on semi-static configuration and / or periodic configuration and / or indication signaling, where the first cell is a first type cell;

[0554] In some embodiments of the first aspect, the first cell is a second type cell, and the first cell transmits the first transmission based on an on-demand mode.

[0555] In some embodiments of the first aspect, the second-type cell transmitting the first transmission in on-demand mode includes at least one of the following:

[0556] The base station autonomously determines whether to transmit the first transmission based on the cell communication status;

[0557] The base station determines whether to transmit the first transmission based on the second transmission sent by the terminal.

[0558] In some embodiments of the first aspect, a terminal in a first cell is unable to receive the first transmission on the time-frequency domain resources determined by the semi-static configuration and / or periodic configuration and / or indication signaling within a first time range based on the semi-static configuration and / or periodic configuration and / or indication signaling; and can receive the first transmission on the time-frequency domain resources determined based on the configuration and / or indication signaling within a second time range, and the first cell is a second type cell.

[0559] In some embodiments of the first aspect, the first cell is a second-category cell, and the first cell does not transmit the first transmission.

[0560] In some embodiments of the first aspect, a terminal in a first cell cannot receive the first transmission, and the cell is a second type cell.

[0561] S2103: The terminal determines a method for receiving the first transmission.

[0562] In some embodiments, the terminal determines the first transmission mode based on the first cell.

[0563] In some embodiments, the terminal determines the manner in which to receive the first transmission based on a type of the first cell.

[0564] In some embodiments, the terminal determines, based on a type of the first cell, a manner of receiving the first transmission based on the first cell.

[0565] In some embodiments, if the first cell is a first type cell, the terminal receives the first transmission according to the configuration of the first transmission of the first cell.

[0566] Exemplarily, the configuration of the first transmission may include: semi-static configuration and / or periodic configuration.

[0567] In some embodiments, the first cell is a first type cell, and it is determined to receive the first transmission according to the configuration of the first transmission when camping on the first cell.

[0568] In some embodiments, if the first cell is a first type cell, the terminal may continue to determine a method for receiving the first transmission from the network side based on a condition of receiving the first transmission based on the first cell.

[0569] In some embodiments, if the first cell is a first type cell and the terminal fails to receive the first transmission based on the configuration of the first cell, it may be because the terminal fails to receive the first transmission due to link failure in the first cell. In this case, in order to successfully receive the first transmission from the first cell, the terminal performs link recovery and receives the first transmission from the first cell after the link is recovered.

[0570] Link recovery here may include but is not limited to beam recovery.

[0571] In some embodiments, if the first cell is a first type cell and the terminal fails to receive the configuration of the first transmission based on the first cell, it may be that the terminal's connection failure in the first cell causes the failure to receive the first transmission. In this case, in order to successfully receive the first transmission from the first cell, the terminal performs connection re-establishment, and the terminal receives the first transmission from the first cell based on the re-established connection.

[0572] It is worth noting that link recovery and connection reestablishment are different processes for the terminal to maintain communication with the first cell.

[0573] In some embodiments, under the condition that the terminal fails to receive the configuration of the first transmission based on the first cell, if the terminal determines that the first cell is a first-type cell, the terminal determines that the failure to receive the first transmission may be caused by the connection failure in the first cell, and the terminal performs link recovery and connection with the first cell, or terminal cell switching or cell reselection to establish connections with other cells.

[0574] If the first cell is a first-category cell, it is determined to perform cell switching or cell reselection.

[0575] In some embodiments, if the terminal determines that the first cell is a first type cell and the terminal fails to receive the first transmission in the first cell, it determines to perform cell switching or cell reselection, thereby changing the terminal's resident cell to another cell to receive the first transmission from the other cell.

[0576] In some embodiments, if the first cell is a first-category cell and the measurement result of the first cell is less than a specified threshold, it is determined to perform cell handover or cell reselection.

[0577] The serving cell of the terminal is changed through cell switching or cell reselection, and the terminal receives the first transmission from the changed serving cell.

[0578] In some embodiments, if the first cell is a first type cell and the terminal fails to continuously receive the first transmission from the first cell, or the terminal still cannot successfully receive the first transmission from the first cell after link recovery or connection re-establishment, it means that the first cell is not suitable for the terminal to continue to reside, and the terminal can change the service cell through processes such as cell selection, cell switching or cell reselection.

[0579] In some embodiments, the first cell is a second type cell, and determining triggers the first cell to send the first transmission.

[0580] In some embodiments, if the first cell is a cell of the second type, it is determined whether the first cell sends the first transmission on demand.

[0581] If the first cell sends the first transmission on demand, the terminal may trigger the first cell to send the first transmission by sending the second transmission.

[0582] In some embodiments, when the first cell is a second-category cell, the terminal determines whether to continue receiving the first transmission from the first cell based on whether the terminal has a configuration for the second transmission of the first cell.

[0583] For example, the first cell is a second-type cell and the terminal has not obtained the configuration of the second transmission corresponding to the first cell, and determines not to continue to receive the first transmission from the first cell. The terminal determines to perform cell switching and / or cell reselection to change the service cell, and receives the first transmission from the replaced service cell.

[0584] Exemplarily, the first cell is a second type cell, and the first cell sends the first transmission according to the demand of being searched by the terminal. In this case, the network side does not need to provide the terminal with the configuration of the second transmission corresponding to the first cell.

[0585] As another example, if the first cell is a second type cell and the terminal does not obtain the configuration of the second transmission corresponding to the first cell, the terminal determines to continue receiving the first transmission from the first cell, and triggers the first cell to send the first transmission by sending the second transmission.

[0586] At this time, the second transmission of the terminal can be sent directly by the terminal to the first cell, or sent to the fourth cell, and the fourth cell sends the first transmission to the first cell through the interface or tunnel between base stations.

[0587] In some embodiments, the first cell is a second type cell, and determining to send the first transmission based on the trigger includes at least one of the following:

[0588] a second transmission sent to the terminal or receiving a second transmission sent by a fourth cell;

[0589] The first transmission is sent to the terminal based on the second transmission.

[0590] In some embodiments, the fourth cell may be a neighboring cell of the first cell.

[0591] In some embodiments, the fourth cell may be a primary cell of the first cell.

[0592] In some embodiments, the fourth cell and the first cell may be any cells with overlapping coverage.

[0593] In other embodiments, if the first cell is a second type cell and the first cell does not send the first transmission, the terminal can change the serving cell when it needs to receive the first transmission. Exemplarily, the terminal changes the serving cell through cell selection, cell switching, and / or cell reselection.

[0594] In some embodiments, if the terminal fails to receive a configuration of a first transmission based on a first cell, and if the terminal determines that the first cell is a second-category cell, the terminal determines that the cell may be in a state where the first transmission is sent on demand. If the terminal requires the first transmission, the terminal sends a request message requesting transmission of the first transmission information.

[0616] In some embodiments, the optional method of S4102 can refer to any optional method of step S2101.

[0617] For terminals that support network energy-saving technology, it is determined based on a predefined method or indication signaling whether the cell is an on-demand SSB / SIB1 cell or an SSB / SIB1-less cell, and the corresponding SSB / SIB1 reception method is determined.

[0618] Exemplarily, an SSB / SIB1-less cell may be a cell that does not send SSB and / or SIB.

[0619] In some embodiments, the on-demand SSB / SIB1 cell and / or the SSB / SIB1-less cell is the aforementioned second type cell. The first type cell may be a cell other than the second type cell.

[0620] Terminal side:

[0621] A terminal supporting network energy saving determines the cell type based on the following scheme and determines whether to receive downlink transmission based on the different cell types. The downlink transmission may include downlink signals and / or downlink channel information. The downlink transmission may include at least SSB and / or SIB1.

[0622] Method 1: A terminal supporting network energy saving determines that a cell is an on-demand SIB1 / SSB cell based on the following method, and requests the base station to send SSB and / or SIB1 by sending a WUS to the base station.

[0623] The terminal determines, according to a predefined method, that the cell is an on-demand SIB1 / SSB cell.

[0624] The terminal does not receive SIB1 / SSB within the first time window.

[0625] The first time window is determined based on a signaling indication or a predefined method.

[0626] The terminal determines that the cell corresponding to the WUS configuration is an on-demand SIB1 / SSB cell. The WUS configuration is obtained based on this cell or other cells.

[0627] The terminal receives the signaling configuration and determines that the cell is an on-demand SIB1 / SSB cell.

[0628] Signaling can be based on SCellConfig configuration.

[0629] Signaling can be based on MIB indications.

[0630] The signaling may be based on the reserved bits of the PBCH or a check method indication.

[0631] Method 2: A terminal supporting network energy saving determines that a cell is a SIB1 / SSB-less cell based on the following method and obtains the corresponding SIB1 / SSB information based on other cells:

[0632] The terminal determines, according to a predefined method, that the cell is an on-demand SIB1 / SSB cell.

[0633] The terminal does not receive SIB1 / SSB within the first time window.

[0634] The first time window is determined based on a signaling indication or a predefined method.

[0635] The terminal receives SIB1 / SSB that does not belong to the current cell in another cell, and determines that the cell corresponding to the SIB1 / SSB is the cell of the on-demand SIB1 / SSB.

[0636] The terminal receives the signaling configuration and determines that the cell is an on-demand SIB1 / SSB cell.

[0637] Signaling can be based on MIB indications.

[0638] The signaling may be based on the reserved bits of the PBCH or a check method indication.

[0639] Base station side:

[0640] A base station supporting network energy saving determines whether to send downlink signals and / or channels based on different cell types, where the signals and / or channels include at least SSB and / or SIB1.

[0641] Method 1: A base station supporting network energy saving indicates that the cell is an on-demand SIB1 / SSB cell based on the following indication signaling, and sends SSB and / or SIB1 based on the on-demand mode:

[0642] The base station sends the WUS configuration corresponding to the on-demand SIB1 / SSB cell.

[0643] The base station sends the following indication signaling to indicate that the cell is an on-demand SIB1 / SSB cell.

[0644] Signaling can be based on SCellConfig configuration.

[0645] Signaling can be based on MIB indications.

[0646] The signaling may be based on the reserved bits of the PBCH or a check method indication.

[0647] Method 2: A base station supporting network energy saving indicates that a cell is a SIB1 / SSB-less cell based on the following indication signaling, and stops sending the corresponding SSB / SIB1.

[0649] Signaling can be based on SCellConfig configuration.

[0650] Signaling can be based on MIB indications.

[0651] The signaling may be based on the reserved bits of the PBCH or a check method indication.

[0652] In this embodiment, it is assumed that the terminal supports network energy-saving technology. The corresponding base station can also support network energy-saving technology. The base station can choose to stop transmitting some downlink signals or channels based on network load, the number of resident terminals, service type, service period, etc. Of course, this patent does not impose any restrictions on the decision-making process and strategy of whether to transmit some downlink signals or channels.

[0653] As mentioned above, the embodiments of the present disclosure mainly define different cells for different behaviors of base stations or terminals. For example, cells can be distinguished by anchor cells or non-anchor cells, or by first-class cells or second-class cells, wherein first-class cells (anchor cells) and second-class cells (non-anchor cells) correspond to different behaviors of sending system information / downlink signals or receiving uplink signals on the network side. Correspondingly, the terminal determines different ways of obtaining system information / downlink signals or sending or receiving uplink signals based on the behaviors of different network-side system cells.

[0654] Downlink transmission includes but is not limited to: SSB, SIB1, TRS, PDCCH, PDSCH, CSI-RS, and other newly defined downlink reference signals, such as PSS and / or SSS, DRS, etc.

[0655] The uplink signal may include but is not limited to at least one of the following: PRACH, SRS, PUCCH, PUSCH, and other newly defined uplink reference signals.

[0656] The embodiments of the present disclosure mainly use SSB and SIB1 as examples to illustrate the embodiments of the present disclosure. It is worth noting that the embodiments of the present disclosure can also be applied to other information / signals, and the embodiments of the present disclosure are not limited to this.

[0657] It is worth noting that the embodiment of the present disclosure uses the first type of cell and the second type of cell to distinguish the different network side behaviors of sending SSB / SIB1 and the corresponding behaviors of obtaining SSB / SIB1. However, the embodiment of the present disclosure does not limit the concepts that need to be introduced. For example, the first type of cell in the embodiment of the present disclosure may refer to a cell in which the network side sends SSB / SIB1 based on the existing semi-static configuration, but a cell that meets the above characteristics is not necessarily defined based on the first type of cell.

[0658] The following examples illustrate possible application scenarios of the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited to the following scenarios:

[0659] Scenario 1: On-demand SSB transmission.

[0660] Network equipment chooses to send SSB on demand based on the number of access users and / or service requirements.

[0661] This scenario mainly corresponds to the terminal being in a connected state and connected to a Scell.

[0662] When the network side is in the on-demand SSB period and does not send the corresponding SSB, the terminal can trigger the corresponding SSB transmission based on the corresponding WUS.

[0663] In this scenario, cells can be divided into first-category cells and second-category cells based on the characteristics of SSB transmission in the cells.

[0664] The description of the first type of cells and the second type of cells can be as follows:

[0665] Category 1 cells: cells where the base station normally sends SSBs based on semi-static configuration;

[0666] Type II cells: cells where the base station sends SSBs based on the on-demand mode;

[0667] Example 1.1:

[0668] Distinguish between first-category cells and second-category cells based on network configuration signaling:

[0669] Exemplarily, the base station may indicate that the Scell ​​is a first-category cell or a second-category cell through a newly defined field in the RRC signaling SCellConfig.

[0670] For example, the base station may indicate that the corresponding Scell ​​is one of the first type cell and / or the second type cell through Scell ​​activation signaling.

[0671] The first type of cells and the second type of cells are distinguished based on the configuration of the WUS.

[0672] Exemplarily, the base station may send the WUS configuration based on a secondary cell configuration (SCellConfig) information element (IE) or other IEs.

[0673] In one embodiment, the WUS configuration may indicate whether the corresponding secondary cell is a first-category cell or a second-category cell.

[0674] In one embodiment, the first type of cells and the second type of cells are distinguished based on the cells to which the WUS configuration is applied.

[0675] For example, the WUS configuration may be based on the Pcell configuration or the Scell ​​configuration. After receiving the WUS configuration and the cell corresponding to the WUS configuration, the terminal determines that the cell corresponding to the WUS configuration is a second-category cell.

[0676] After receiving the WUS configuration, if the terminal determines that the corresponding secondary cell Scell ​​is a first-category cell, the terminal receives the corresponding SSB based on the SSB corresponding semi-static signaling configuration.

[0677] Example 1.3: Exemplarily, it can be determined based on a predefined manner.

[0678] If the terminal does not receive the corresponding SSB within the first time window, the terminal determines that the cell is a second type cell.

[0679] The first time window may be determined based on signaling or a predefined manner.

[0680] Exemplarily, the first time window is N consecutive configured SSB periods.

[0681] The starting position of the first time window is the period in which the terminal currently receives the SSB. N is determined based on a predefined or signaling configuration, and illustratively, N=3.

[0682] If it is determined that the corresponding Scell ​​is a second type cell, the terminal sends a WUS as needed to request the transmission of the corresponding SSB.

[0683] If it is determined that the corresponding Scell ​​is a second type cell, the terminal determines that it cannot receive the corresponding SSB within a period of time.

[0684] The WUS that triggers SSB transmission can be sent on the primary cell or the secondary cell.

[0685] In some embodiments, the WUS may be specific RRC signaling, MAC CE signaling, or a physical layer signal.

[0686] Based on the above scenario, the way in which the terminal obtains SSB may be as shown in FIG. 5A or FIG. 5B .

[0687] As shown in FIG5A , the downlink transmission method performed by the terminal may include:

[0688] Step 1: Determine that the cell is a first-class cell;

[0689] Step 2: The gNB of the second type of cell stops sending SSB.

[0690] Step 3: The terminal attempts to receive SSB but fails.

[0691] Step 4: The terminal sends WUS;

[0692] Step 5: gNB receives WUS;

[0693] Step 6: gNB sends SSB.

[0694] As shown in FIG5A , the downlink transmission method performed by the terminal may include:

[0695] Step 1: Determine that the cell is a second-category cell;

[0696] Step 2: Send SSB;

[0697] Step 3: The terminal fails to receive SSB.

[0698] Step 4: The terminal continues to try to receive SSB.

[0699] If the terminal determines that the cell is a first-class cell scenario, if the terminal cannot normally receive the corresponding SSB, the terminal confirms that the reception failure is from the transmission link. Based on this, the terminal can continue to try to receive the SSB, or initiate cell switching, cell search and other processes.

[0700] Scenario 2: On-demand SIB1 in a single-carrier scenario

[0701] The network can choose to send SIB1 on-demand based on user access and / or service requirements. This scenario primarily applies to terminals in idle and / or inactive states. When the network is in an on-demand SIB1 period and does not send the corresponding SIB1, the terminal can trigger the corresponding SIB1 transmission based on the corresponding WUS.

[0702] If the terminal sends the corresponding WUS, it needs to obtain the corresponding WUS configuration.

[0703] Considering that the scenario mainly corresponds to a single carrier scenario.

[0704] In a single carrier scenario, the terminal may not be able to obtain the corresponding WUS configuration through other cells and can only obtain the corresponding WUS configuration through the current cell. As shown in Figure 5C, there is no terminal in the cell, reducing the transmission of common signals or channels. When a terminal enters, the base station is awakened and the transmission of common signals or channels is started. As shown in Figure 5D, in the time domain, the terminal does not send SIB1 before monitoring WUS, but can send reference signals such as SSB and / or DRS, and starts periodic transmission or one-time transmission of SIB1 after monitoring WUSD.

[0705] In this scenario, based on the characteristics of SIB1 transmission in the cell, the cell can be divided into the first type of cell and the second type of cell. The first type of cell: a cell where the base station normally transmits SIB1 based on semi-static configuration.

[0706] Second type of cell: a cell where the base station sends SIB1 based on the on-demand mode.

[0707] The first type of cells and the second type of cells may be distinguished in at least one of the following ways:

[0708] Embodiment 2.1: The first type of cell and the second type of cell may be determined based on a predefined method.

[0709] If the terminal does not receive the corresponding SIB1 within the first time window, the terminal determines that the cell is a second type cell.

[0710] The first time window may be determined based on signaling or a predefined manner.

[0711] Exemplarily, the first time window is N consecutive configured SIB1 periods, and the SIB1 period may be a blind detection period of a type 0 CSS for scheduling SIB1.

[0712] The starting position of the first time window is the period of the terminal's current blind detection of type 0 CSS. N is determined based on a predefined or signaling configuration manner. For example, N=3.

[0713] For example, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects DCI1_0 of the SI-RNTI check based on the above Searchspace#0 and CORESET#0.

[0714] If the terminal fails to detect the corresponding DCI of the scheduling SIB1 for M consecutive blind detection periods, the cell is determined to be a second-category cell.

[0715] If the terminal fails to detect the corresponding scheduling SIB1 for M consecutive blind detection periods, and fails to receive the corresponding SIB1 when the corresponding DCI is detected blindly, the terminal determines that the cell is a second type cell.

[0716] Exemplarily, the terminal determines the state of the cell in the following manner: If the terminal does not receive the corresponding SIB1 within a first time window, the terminal determines the type of the corresponding cell. The first time window starts with the current SIB1 blind detection period of the terminal and N consecutive configured SIB1 periods.

[0717] The corresponding cell may be a cell corresponding to on-demand SIB1, or a cell that the terminal is prohibited from accessing.

[0718] The terminal stores the status information of the cell.

[0719] After receiving the configuration of the WUS corresponding to the cell, the terminal determines that the cell may be the cell corresponding to the on-demand SIB1. Otherwise, the cell may be a cell that the terminal is prohibited from accessing.

[0720] M is determined based on a predefined or signaling configuration. For example, M=1.

[0721] A blind detection period here may be the aforementioned receiving opportunity.

[0722] For example, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects the DCI1_0 of the SI-RNTI verification based on the above Searchspace#0 and CORESET#0, and successfully receives the corresponding SIB1.

[0723] If the terminal successfully camps on the cell and needs to obtain updated system information, for example, if the terminal fails to blindly detect the corresponding DCI scheduling SIB1 for M consecutive blind detection periods, and / or blindly detects the corresponding DCI but does not receive the corresponding SIB1, the terminal determines that the cell is a second-category cell. M is determined based on a predefined or signaling configuration, and illustratively, M=1.

[0724] For example, when a terminal enters a network coverage area from outside the network coverage area, it needs to obtain updated system information; or when a terminal switches from a network using other wireless access technologies to the current network, it needs to obtain system information.

[0725] Embodiment 2.2: exemplary differentiation between first-category cells and second-category cells based on WUS configuration.

[0726] The WUS configuration is used for the terminal to send a WUS on the configured resources, and the WUS can trigger SIB1 transmission.

[0727] Exemplarily, if the terminal searches for the SSB corresponding to the cell through cell search, and obtains the corresponding WUS configuration based on the SSB.

[0728] As another example, the terminal attempts to and successfully receives the corresponding WUS configuration before receiving the SSB but receiving the SIB1, and the terminal determines that the cell is a second type cell.

[0729] For example, if the terminal searches for the SSB corresponding to the cell through a cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects DCI1_0 of the SI-RNTI check based on the above Searchspace#0 and CORESET#0, and successfully receives the corresponding SIB1. The terminal successfully receives the corresponding WUS configuration, and the terminal determines that the cell is a second type cell.

[0730] Embodiment 2.3: Exemplarily, the distinction may be based on indication signaling, and the indication signaling may be carried based on MIB or MIB and PBCH.

[0731] Example 2.3-1: The indication signaling may be an idle bit in the MIB. For example, if the idle bit indication is 0, it indicates that the corresponding cell is a first-category cell; if the idle bit indication is 1, it indicates that the corresponding cell is a first-category cell.

[0732] The indication signaling may be the last bit of ssb-SubcarrierOffset in the MIB. For example, if the idle bit indication is 0, it indicates that the corresponding cell is a first-category cell; if the idle bit indication is 1, it indicates that the corresponding cell is a first-category cell.

[0733] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding MIB, it can determine based on signaling whether the cell to which it belongs is a first-category cell or a second-category cell.

[0734] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding MIB, they will determine that they are idle (idle bits are reserved), and the legacy terminals ignore the information field indication.

[0735] Example 2.3-2: The indication signaling may be Kssb. Kssb is jointly indicated based on ssb-SubcarrierOffset and information bits within the PBCH.

[0736] Example 2.3-2-1: The SSB of the corresponding cell may be the cell associated with CORESET#0.

[0737] For FR1, Kssb is greater than or equal to 0 and less than or equal to 23.

[0738] For FR2, Kssb is greater than or equal to 0 and less than or equal to 13.

[0739] When Kssb belongs to the first value set, the cell associated with SSB is a first type cell.

[0740] When Kssb belongs to the second value set, the cell associated with SSB is a second type of cell.

[0741] The first value set may be determined based on signaling or a predefined method. For example, the first value set corresponds to an even number for Kssb, and the second value set corresponds to an odd number for Kssb. For another example, the first value set includes a value range that is different from the value range of the second value set.

[0742] Exemplarily, the indication signaling can also be an indication bit corresponding to the radio frame number (systemFrameNumber, SFN), subCarrierSpacingCommon, dmrs-TypeA-Position, cellBarred, intraFreqReselection, etc. When the indication bit belongs to the first value set, the cell associated with the SSB is a first type cell.

[0743] When Kssb belongs to the second value set, the cell associated with SSB is a second type of cell.

[0744] This embodiment of the present disclosure will not be elaborated on this.

[0745] For terminals that support network energy saving, after receiving SSB and reading the corresponding Kssb, it can determine based on signaling whether the cell to which it belongs is a first type cell or a second type cell, and determine the frequency domain position of CRB based on Kssb.

[0746] For terminals that do not support network energy saving, after receiving SSB and reading the corresponding Kssb, the frequency domain position of CRB can be determined based on Kssb.

[0747] Example 2.3-2-2: The SSB of the corresponding cell may be a cell that is not associated with CORESET#0.

[0748] For FR1, Kssb is greater than or equal to 24.

[0749] For FR2, Kssb is greater than or equal to 13.

[0750] When Kssb belongs to the first value set, the cell associated with SSB is a first type cell.

[0751] When Kssb belongs to the second value set, the cell associated with SSB is a second type of cell.

[0752] The first value set may be determined based on signaling or a predefined method. For example, the second value set corresponds to Kssb=30,

[0753] The first value set is that Kssb is not equal to 30.

[0754] Exemplarily, for a terminal that supports network energy saving, after receiving the SSB and reading the corresponding Kssb=30, it can be determined based on signaling that the cell is a second-type cell, and the frequency domain position of the CRB can be determined based on Kssb.

[0755] The specific method is as follows:

[0756] The terminal determines the lowest subcarrier of SSB and N based on Kssb-offset CRB The offset of the lowest subcarrier, N CRB It is the lowest CRB that has frequency domain intersection with CRB.

[0757] Kssb-offset=Kssb-9, or Kssb-offset=Kssb mod 24; this method can be applied to the scenario where Kssb=30, and can also be applied to scenarios with other Kssb values.

[0758] For example, for a terminal supporting network energy saving, under the condition that the cell is determined to be a second-category cell based on signaling, the corresponding pdcch-ConfigSIB1 can be read to determine the corresponding SearchSpace#0 or CORESET#0;

[0759] For legacy terminals that do not support network energy saving, when the Kssb of the corresponding SSB meets the above conditions, it can be determined that the SSB is not associated with CORESET#0. During the cell search process, the terminal continues to search for other SSBs to obtain the SSB associated with CORESET#0.

[0760] Embodiment 2.4: differentiation can be based on indication signaling.

[0761] The indication signaling may be carried based on the PBCH.

[0762] Example 2.4-1: The indication signaling may be a reserved bit in the PBCH.

[0763] For example, Conditional Bit, or Less than or equal to 8 or bit.

[0764] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding PBCH reserved bit, it can be determined based on the signaling that the cell to which it belongs is one of the first type of cell or the second type of cell.

[0765] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding PBCH, the legacy terminal ignores the reserved bit information field indication. Exemplarily, the reserved bit can be determined based on Table 4:

[0766] Table 4

[0767] Example 2.4-2:

[0768] The indication signaling can be a different CRC within the PBCH. For example, a new CRC is introduced, and a base station supporting network energy conservation checks the PBCH based on the newly introduced CRC and sends the corresponding signal. A terminal supporting network energy conservation demodulates the corresponding PBCH based on the new CRC check and, upon successful reception of the PBCH, determines that the cell is a Category II cell.

[0769] A terminal supporting network energy saving demodulates the corresponding PBCH based on the existing CRC check and, after successfully receiving the PBCH, determines that the cell is a Class I cell. A terminal not supporting network energy saving demodulates the corresponding PBCH based on the existing CRC check and fails to successfully demodulate the corresponding PBCH, and continues the cell search process.

[0770] For example, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects the SI-RNTI verified DCI1_0 based on the above Searchspace#0 and CORESET#0.

[0771] If the terminal fails to detect the corresponding DCI scheduling SIB1 for M consecutive blind detection periods, and / or detects the corresponding DCI but does not receive the corresponding SIB1, the terminal determines that the cell is a second-category cell. M is determined based on a predefined or signaling configuration, and illustratively, M=1.

[0772] Exemplarily, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects the DCI1_0 verified by SI-RNTI based on the above Searchspace#0 and CORESET#0, and successfully receives the corresponding SIB1. If the terminal successfully camps on the cell, and when it needs to obtain updated system information, for example, the terminal returns from out of coverage, or the terminal after entering the network from another RAT, if the terminal does not blindly detect the DCI of the corresponding scheduling SIB1 for M consecutive blind detection periods, and / or blindly detects the corresponding DCI but does not receive the corresponding SIB1, the terminal determines that the cell is a second type cell. M is determined based on a predefined or signaling configuration method. Exemplarily, M=1;

[0773] Scenario 3: Multi-carrier on-demand SIB1 transmission scenario.

[0774] The network side chooses to send SIB1 on demand based on the access user and / or service requirements, etc. This scenario mainly corresponds to terminals in idle and / or inactive states.

[0775] As shown in Figure 5E, when the network side is in the on-demand SIB1 period and does not send the corresponding SIB1, the terminal can trigger the corresponding SIB1 transmission based on the corresponding WUS.

[0776] If the terminal sends WUS to trigger the network side to send SSB and / or SIB1, the terminal needs to obtain the WUS configuration.

[0777] Considering that the scenario mainly corresponds to a multi-carrier scenario, in the multi-carrier scenario, the terminal can obtain the corresponding WUS configuration only for the anchor cell, or can obtain the corresponding WUS configuration based on the anchor cell or non-anchor cell.

[0778] In this scenario, two types of cells are defined, namely first type cells and second type cells.

[0779] Category 1 cell: a cell where the base station normally sends SIB1 based on semi-static configuration. For example, the cell may be a cell that sends WUS configuration of other cells. For example, the cell may be an anchor cell.

[0780] Second type of cell: a cell in which the base station sends SIB1 based on the on-demand mode. Exemplarily, the cell may send the WUS configuration of the cell or other cells. Exemplarily, the cell may not send the corresponding WUS configuration. Exemplarily, the cell may be a non-anchor cell.

[0781] The two cells can be distinguished based on the following:

[0782] Example 3.1: It can be determined based on a predefined method.

[0783] If the terminal does not receive the corresponding SIB1 within the first time window, the terminal determines that the cell is a second-category cell. The first time window can be determined based on signaling or a predefined method. Exemplarily, the first time window is N consecutive configured SIB1 periods, and the SIB1 period can be a blind detection period for the type 0 CSS that schedules SIB1. The starting position of the first time window is the period of the terminal's current blind detection of the type 0 CSS. N is determined based on a predefined or signaling configuration method. Exemplarily, N = 3.

[0784] Exemplarily, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects the DCI1_0 of the SI-RNTI check based on the above Searchspace#0 and CORESET#0. If the terminal fails to blindly detect the DCI of the corresponding scheduling SIB1 for M consecutive blind detection cycles, and / or blindly detects the corresponding DCI but does not receive the corresponding SIB1, the terminal determines that the cell is a second type cell. M is determined based on a predefined or signaling configuration method, and exemplarily, M=1.

[0785] For example, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects the DCI1_0 of the SI-RNTI verification based on the above Searchspace#0 and CORESET#0, and successfully receives the corresponding SIB1.

[0786] If the terminal successfully camps on the cell and needs to obtain updated system information, for example, if the terminal fails to blindly detect the corresponding DCI scheduling SIB1 for M consecutive blind detection periods, and / or blindly detects the corresponding DCI but does not receive the corresponding SIB1, the terminal determines that the cell is a second type cell. M is determined based on a predefined or signaling configuration method, and illustratively, M=1;

[0787] Exemplarily, if the terminal does not obtain the WUS configuration of the cell corresponding to the SSB, the terminal will continue to search for other cells. For example, the terminal obtains the WUS configuration of the second type of cell based on the SSB of the first type of cell. After obtaining the WUS configuration, the terminal returns to the second type of cell based on cell selection or cell reselection, and sends the SIB1 transmission corresponding to the WUS request.

[0788] For example, if the terminal does not obtain the WUS configuration of the cell corresponding to the SSB, the terminal will continue to search for other cells, for example, the SSB of the first type of cell, to obtain the WUS configuration of the second type of cell. After obtaining the WUS configuration, the terminal sends a WUS request for the second type of cell in the first type of cell. The WUS request carries information about the second type of cell. After the first type of cell base station transmits the request to the second type of cell base station through information exchange, the second type of cell base station receives the WUS.

[0789] Exemplarily, under the condition that the terminal has obtained the WUS configuration of the cell corresponding to the SSB, the terminal will send the SIB1 transmission corresponding to the WUS request in the second type of cell.

[0790] Embodiment 3.2: The first type of cells and the second type of cells may be distinguished based on WUS configuration. The WUS configuration is used for the terminal to send a WUS on the configured resources to trigger corresponding SIB1 transmission.

[0791] For example, if the terminal searches for the SSB corresponding to the cell through a cell search and obtains the WUS configuration corresponding to the cell based on the SSB, or if the terminal attempts to and successfully receives the WUS configuration corresponding to the cell before receiving the SSB but before receiving the SIB1, the terminal determines that the cell corresponding to the WUS configuration is a second type cell.

[0792] For example, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects DCI1_0 of the SI-RNTI check based on the above Searchspace#0 and CORESET#0, and successfully receives the corresponding SIB1. The terminal successfully receives the WUS configuration corresponding to the cell, and the terminal determines that the cell is a second type cell.

[0793] Exemplarily, if the terminal searches for the SSB corresponding to the first type of cell through cell search and successfully receives the WUS configuration of the specific cell in the first type of cell, the terminal determines that the cell corresponding to the WUS configuration is the second type of cell.

[0794] Embodiment 3.3: The first type of cells and the second type of cells can be distinguished based on indication signaling.

[0795] The indication signaling may be carried based on the MIB or the MIB and the PBCH.

[0796] Example 3.3-1: The indication signaling may be an idle bit in the MIB.

[0797] Exemplarily, if the spare bit indication is 0, it indicates that the corresponding cell is a first-category cell; if the spare bit indication is 1, it indicates that the corresponding cell is a first-category cell.

[0798] The indication signaling may be the last bit of the ssb-SubcarrierOffset in the MIB. For example, if the spare bit indication is 0, it indicates that the corresponding cell is a first-category cell. If the spare bit indication is 1, it indicates that the corresponding cell is a first-category cell.

[0799] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding MIB, it can determine based on signaling whether the cell to which it belongs is a first-category cell or a second-category cell.

[0800] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding MIB, the legacy terminal ignores the information field indication of the idle bit.

[0801] Example 3.3-2: The indication signaling may be Kssb. Kssb is jointly indicated based on ssb-SubcarrierOffset and information bits within the PBCH.

[0802] Example 3.3-2-1: Exemplarily, the SSB of the corresponding cell may be the cell associated with CORESET#0, that is, the corresponding Kssb is greater than or equal to 0 and less than or equal to 23 (for FR1), and Kssb is greater than or equal to 0 and less than or equal to 13 (for FR2). When Kssb belongs to the first value set, the cell associated with the SSB is a first-category cell; when Kssb belongs to the second value set, the cell associated with the SSB is a second-category cell.

[0803] The first value set may be determined based on signaling or a predefined method. For example, the first value set corresponds to an even number for Kssb, and the second value set corresponds to an odd number for Kssb.

[0804] Exemplarily, the indication signaling may also be an indication bit corresponding to SFN (systemFrameNumber), subCarrierSpacingCommon, dmrs-TypeA-Position, cellBarred, intraFreqReselection, etc. When the indication bit belongs to the first value set, the cell associated with the SSB is a first type of cell, and when Kssb belongs to the second value set, the cell associated with the SSB is a second type of cell. This embodiment of the present disclosure will not be described in detail.

[0805] For terminals that support network energy saving, after receiving SSB and reading the corresponding Kssb, it can determine based on signaling whether the cell to which it belongs is a first type cell or a second type cell, and determine the frequency domain position of CRB based on Kssb.

[0806] For terminals that do not support network energy saving, after receiving SSB and reading the corresponding Kssb, the frequency domain position of CRB can be determined based on Kssb.

[0807] Example 3.3-2-2:

[0808] The SSB of the corresponding cell may be a cell not associated with CORESET#0, that is, the corresponding Kssb is greater than or equal to 24 (for FR1), or Kssb is greater than or equal to 13 (for FR2). When Kssb belongs to the first value set, the cell associated with the SSB is a first type of cell. When Kssb belongs to the second value set, the cell associated with the SSB is a second type of cell.

[0809] The first value set may be determined based on signaling or a predefined manner. For example, the second value set corresponds to Kssb=30, and the first value set corresponds to Kssb not being equal to 30.

[0810] In some embodiments, the terminal determines Kssb based on network signaling and determines the subcarrier spacing based on Kssb.

[0811] In some embodiments, Kssb is less than a specified value and the subcarrier spacing may be considered equal to Kssb.

[0812] In some embodiments, Kssb is greater than or equal to a specified value, and the subcarrier spacing may be determined based on Kssb.

[0813] Exemplarily, the designated value may include but is not limited to any value greater than or equal to 24, for example, 30. The network signaling may include but is not limited to: MIB, PBCH information, SIB and other signaling sent by the network side.

[0814] For example, for a terminal that supports network energy saving, after receiving an SSB and reading the corresponding Kssb=30, it can determine based on signaling that the cell is a second-class cell, and determine the frequency domain position of the CRB based on Kssb. The specific method is as follows:

[0815] The terminal determines the lowest subcarrier of SSB and N based on Kssb-offset CRB The offset of the lowest subcarrier, N CRB The lowest CRB that has frequency domain intersection with the CRB. Kssb-offset = Kssb-9, or Kssb-offset = Kssb mod 24. This can be applied to scenarios where Kssb = 30 or other Kssb values.

[0816] For example, for a terminal supporting network energy saving, under the condition that the cell is determined to be a second-category cell based on signaling, the corresponding pdcch-ConfigSIB1 can be read to determine the corresponding SearchSpace#0 or CORESET#0;

[0817] For legacy terminals that do not support network energy saving, when the Kssb of the corresponding SSB meets the above conditions, it can be determined that the SSB is not associated with CORESET#0. During the cell seach process, the terminal continues to search for other SSBs to obtain the SSB associated with CORESET#0.

[0818] Embodiment 3.4: differentiation can be based on indication signaling.

[0819] The indication signaling can be carried based on the PBCH, that is, the cell type can be distinguished through the PBCH information.

[0820] Example 3.4-1: The indication signaling may be a reserved bit in the PBCH. For example, Conditional Bit, or Less than or equal to 8 or bit.

[0821] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding PBCH reserved bit, it can be determined based on the signaling that the cell to which it belongs is one of the first type of cell or the second type of cell.

[0822] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding PBCH, the legacy terminals ignore the reserved bit information field indication.

[0823] Example 3.4-2: The indication signaling may be a different CRC in the PBCH. For example, a new CRC is introduced, and the base station supporting network energy saving checks the PBCH based on the newly introduced CRC and sends the corresponding information.

[0824] The terminal supporting network energy saving demodulates the corresponding PBCH based on the new CRC check, and after successfully receiving the PBCH, determines that the cell is a second type cell.

[0825] The terminal supporting network energy saving demodulates the corresponding PBCH based on the existing CRC check, and after successfully receiving the PBCH, determines that the cell is a first-category cell.

[0826] The terminal that does not support network energy saving demodulates the corresponding PBCH based on the existing CRC check, but fails to successfully demodulate the corresponding PBCH and continues to perform a cell search process.

[0827] For example, if the terminal determines that the cell is a second-category cell and has not obtained the corresponding SIB1, under the condition that the terminal has not obtained the WUS configuration of the cell corresponding to the SSB, the terminal will continue to search for other cells, for example, the SSB of the first-category cell, to obtain the WUS configuration of the second-category cell. After obtaining the WUS configuration, the terminal returns to the second-category cell based on cell selection or cell reselection, and sends a WUS request for the corresponding SIB1 transmission;

[0828] For example, if the terminal determines that the cell is a second-category cell and has not obtained the corresponding SIB1, and if the terminal has not obtained the WUS configuration of the cell corresponding to the SSB, the terminal will continue to search for other cells, such as the SSB of the first-category cell, to obtain the WUS configuration of the second-category cell. After obtaining the WUS configuration, the terminal sends a WUS request for the second-category cell in the first-category cell. The WUS request carries information about the second-category cell. After the first-category cell base station transmits the request to the second-category cell base station through information exchange, the second-category cell base station receives the WUS request.

[0829] For example, if the terminal determines that the cell is a second-class cell and has not obtained the corresponding SIB1, under the condition that the terminal has obtained the WUS configuration of the cell corresponding to the SSB, the terminal will send a WUS request in the second-class cell to transmit the corresponding SIB1.

[0830] For example, if the terminal determines that the cell is a second-category cell and successfully obtains the corresponding SIB1, the terminal can receive the corresponding WUS configuration based on the cell. If it subsequently needs to obtain and update the SIB1, the terminal can send a WUS request based on the configuration to obtain the corresponding SIB1.

[0831] Scenario 4: SIB1 / SSB-less cell

[0832] The network side chooses not to send SIB1 / SSB based on access users and / or service requirements.

[0833] This scenario mainly applies to terminals in idle and / or inactive states. As shown in Figure 5F, when the cell corresponding to carrier component (CC) 3 or CC2 does not send the corresponding SIB1 / SSB, the terminal can obtain the SIB1 / SSB of CC2 or CC3 based on CC1.

[0834] The embodiments of the present disclosure take SIB1 as an example to illustrate the solutions of the embodiments of the present disclosure. Other signals, such as SSB, are also within the protection scope of the solutions of the embodiments of the present disclosure and are not limited thereto.

[0835] Based on this scenario, the correspondence can be defined as follows:

[0836] Type 1 cell: a cell where the base station normally sends SIB1 based on semi-static configuration. For example, the cell may send SIB1 information of at least one cell including the cell itself. For example, the cell may be CC1 corresponding to Figure 5F;

[0837] Second type of cell: a cell where the base station does not send SIB1. For example, the cell may be CC2 corresponding to FIG5F ;

[0838] The two cells can be distinguished based on the following:

[0839] Embodiment 4.1: The type of the cell may be determined based on a predefined manner.

[0840] If the terminal does not receive the corresponding SIB1 within the first time window, the terminal determines that the cell is a cell of the second type. The first time window may be determined based on signaling or a predefined method.

[0841] Exemplarily, the first time window is N consecutive configured SIB1 periods, and the SIB1 period may be a blind detection period of a type 0 CSS for scheduling SIB1.

[0842] The starting position of the first time window is the period of the terminal's current blind detection of type 0 CSS. N is determined based on a predefined or signaling configuration manner. For example, N=3.

[0843] For example, if the terminal searches for the SSB corresponding to the cell through cell search, and determines the information corresponding to Searchspace#0 and CORESET#0 based on the MIB configuration in the SSB, and blindly detects the SI-RNTI verified DCI1_0 based on the above Searchspace#0 and CORESET#0.

[0844] If the terminal fails to detect the corresponding DCI scheduling SIB1 for M consecutive blind detection periods, and / or detects the corresponding DCI but does not receive the corresponding SIB1, the terminal determines that the cell is a second-category cell. M is determined based on a predefined or signaling configuration, and illustratively, M=1.

[0845] For example, if the terminal fails to obtain the SIB1 of the cell corresponding to the SSB, the terminal will continue to search for other cells, for example, the SSB of the first type of cell, to obtain the SIB1 of the second type of cell. After obtaining the SIB1, the terminal returns to the second type of cell based on cell selection or cell reselection, receives the corresponding SSB, and can initiate a RACH process based on the SSB and the obtained SIB1 of the second type of cell.

[0846] Exemplarily, under the condition that the terminal has obtained SIB1 of the cell corresponding to the SSB, the terminal can initiate a RACH process in the second type of cell.

[0847] Exemplarily, the terminal determines the state of the cell based on the following method: If the terminal does not receive the corresponding SIB1 within a first time window, the terminal determines that the cell is a first subclass cell or a second subclass cell in the second class cell. The first time window starts with the blind detection period of the current SIB1 in which the terminal is located and N consecutive configured SIB1 periods.

[0848] The first sub-category cell is a cell corresponding to the on-demand SIB1, and the second sub-category cell is a cell prohibited to the terminal.

[0849] The terminal stores the status information of the cell.

[0850] After receiving the WUS configuration corresponding to the cell, the cell is determined to be a first sub-category cell; otherwise, the cell is determined to be a second sub-category cell.

[0851] Example 4.2: The cell types may be distinguished based on SIB1.

[0852] Exemplarily, if the terminal searches for the SSB corresponding to the first type of cell through cell search and successfully receives the SIB1 of the specific cell in the first type of cell, the terminal determines that the cell corresponding to the SIB1 is the second type of cell.

[0853] Example 4.3: Exemplarily, the distinction can be based on indication signaling, which can be carried based on the MIB or the MIB and PBCH. Example 4.3-1: The indication signaling can be an idle bit in the MIB. Exemplarily, if the idle bit indicates 0, it indicates that the corresponding cell is a first-category cell. If the idle bit indicates 1, it indicates that the corresponding cell is a first-category cell.

[0854] The indication signaling may be the last bit of ssb-SubcarrierOffset in the MIB. For example, if the idle bit indication is 0, it indicates that the corresponding cell is a first-category cell; if the idle bit indication is 1, it indicates that the corresponding cell is a first-category cell.

[0855] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding MIB, it can determine based on signaling whether the cell to which it belongs is a first-category cell or a second-category cell.

[0856] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding MIB, the idle bit reservation is determined. The legacy terminal ignores the information field indication. Alternatively, the ssb-SubcarrierOffset is used to determine the CRB offset of the SSB.

[0857] Example 4.3-2: The indication signaling may be Kssb. Kssb is jointly indicated based on ssb-SubcarrierOffset and information bits within the PBCH.

[0858] Example 4.3-2-1: Exemplarily, the SSB of the corresponding cell may be a cell associated with CORESET#0.

[0859] For FR1, Kssb is greater than or equal to 0 and less than or equal to 23.

[0860] For FR2, KssbKssb is greater than or equal to 0 and less than or equal to 13.

[0861] When Kssb belongs to the first value set, the cell associated with SSB is a first type cell.

[0862] When Kssb belongs to the second value set, the cell associated with SSB is a second type of cell.

[0863] The first value set may be determined based on signaling or a predefined method. For example, the first value set corresponds to an even number for Kssb, and the second value set corresponds to an odd number for Kssb.

[0864] Exemplarily, the indication signaling may also be an indication bit corresponding to SFN (systemFrameNumber), subCarrierSpacingCommon, dmrs-TypeA-Position, cellBarred, intraFreqReselection, etc. When the indication bit belongs to the first value set, the cell associated with the SSB is a first type of cell, and when Kssb belongs to the second value set, the cell associated with the SSB is a second type of cell. This embodiment of the present disclosure will not be described in detail.

[0865] For terminals that support network energy saving, after receiving SSB and reading the corresponding Kssb, it can determine based on signaling whether the cell to which it belongs is a first type cell or a second type cell, and determine the frequency domain position of CRB based on Kssb.

[0866] Exemplarily, under the condition that the terminal determines that the cell is a second-category cell, if the terminal has obtained SIB1 information corresponding to the second-category cell, the terminal receives the cell SSB and may attempt to access the cell.

[0867] For example, if the terminal determines that the cell is a second-category cell and still has not obtained the SIB1 information corresponding to the second-category cell, the terminal will continue to search for SSBs of other cells until it finds a first-category cell and obtains the corresponding SIB1 information.

[0868] For terminals that do not support network energy saving, after receiving SSB and reading the corresponding Kssb, the frequency domain position of CRB can be determined based on Kssb.

[0869] Example 4.3-2-2: The SSB of the second type of cell may be a cell that is not associated with CORESET#0.

[0870] For FR1, Kssb is greater than or equal to 24.

[0871] For FR2, Kssb is greater than or equal to 13.

[0872] Exemplarily, the SSB of the first type of cell may be a cell associated with CORESET#0.

[0873] For FR1, the corresponding Kssb is less than 24.

[0874] For FR2, Kssb is less than 13.

[0875] When Kssb belongs to the first value set, the cell associated with SSB is a first type cell. When Kssb belongs to the second value set, the cell associated with SSB is a second type cell.

[0876] The first value set may be determined based on signaling or a predefined manner. For example, the second value set corresponds to Kssb=30.

[0877] The first value set is that Kssb is not equal to 30.

[0878] For example, for a terminal that supports network energy saving, after receiving an SSB and reading the corresponding Kssb, it can determine that the cell is a second-category cell based on signaling, and determine the frequency domain position of the CRB based on Kssb. The specific method is as follows:

[0879] The terminal determines the SSB lowest subcarrier and N_ based on Kssb-offset CRB The offset of the lowest subcarrier, NCRB is the lowest CRB that has frequency domain intersection with CRB.

[0880] N_ CRB The common resource block (CRB) with the smallest frequency domain index among the CRBs where the SSB is located and has an overlapping frequency domain.

[0881] Kssb-offset is the offset of Kssb.

[0882] For FR1, Kssb-offset=Kssb-8, or Kssb-offset=Kssb mod 24.

[0883] For FR2, Kssb-offset=Kssb-4, or Kssb-offset=Kssbmod 12.

[0884] Illustratively, during a cell search process, under the condition that the terminal determines that the cell is a second-category cell, if the terminal has acquired SIB1 information corresponding to the second-category cell, the terminal receives the cell SSB and may attempt to access the cell.

[0885] For example, if the terminal determines that the cell is a second-category cell and still has not obtained the SIB1 information corresponding to the second-category cell, the terminal will continue to search for SSBs of other cells until it finds a first-category cell and obtains the corresponding SIB1 information.

[0886] For legacy terminals that do not support network energy saving, when the Kssb of the corresponding SSB meets the above conditions, it can be determined that the SSB is not associated with CORESET#0. During the cell seach process, the terminal continues to search for other SSBs to obtain the SSB associated with CORESET#0.

[0887] Example 4.4: Exemplarily, the distinction can be based on indication signaling, and the indication signaling can be carried based on PBCH.

[0888] Example 4.4-1: The indication signaling may be a reserved bit in the PBCH. For example, Conditional Bit, or Less than or equal to 8 or bit.

[0889] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding PBCH reserved bit, it can be determined based on the signaling that the cell to which it belongs is one of the first type of cell or the second type of cell.

[0890] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding PBCH, the legacy terminals ignore the reserved bit information field indication.

[0891] Embodiment 4.4-2: The indication signaling may be a different CRC in the PBCH. For example, a new CRC is introduced, and the base station supporting network energy saving checks the PBCH based on the newly introduced CRC and sends the corresponding information.

[0892] The terminal supporting network energy saving demodulates the corresponding PBCH based on the new CRC check, and after successfully receiving the PBCH, determines that the cell is a second type cell.

[0893] A terminal supporting network energy saving demodulates the corresponding PBCH based on the existing CRC check and, after successfully receiving the PBCH, determines that the cell is a Class I cell. A terminal not supporting network energy saving demodulates the corresponding PBCH based on the existing CRC check and fails to successfully demodulate the corresponding PBCH, and continues the cell search process.

[0894] For example, if the terminal determines that the cell is a second-category cell and has not obtained the corresponding SIB1, the terminal will continue to search for other cells, for example, the SSB of the first-category cell, to obtain the SIB1 of the second-category cell. After obtaining the SIB1, the terminal returns to the second-category cell based on cell selection or cell reselection;

[0895] For example, if the terminal determines that the cell is a second-class cell and has not obtained the corresponding SIB1, under the condition that the terminal has obtained the WUS configuration of the cell corresponding to the SSB, the terminal will send a WUS request in the second-class cell to transmit the corresponding SIB1.

[0896] Exemplarily, if the terminal determines that the cell is a second-category cell and successfully obtains the corresponding SIB1, the terminal may continue to receive other system information based on the cell, or initiate a RACH process.

[0897] The embodiments of the present disclosure mainly determine different cell types based on different scenarios and design methods, which is conducive to achieving consistent understanding between base stations and terminals and reducing terminal operation complexity.
