[0138] like Figure 1A As shown, the communication system 100 includes a terminal 101 and a network device 102. The network device 102 may include an access network device and / or a core network device.

[0148] 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 the terminal.
[0149] like Figure 1BAs shown, the base station in the energy-saving state stops periodically sending SSB and / or SIB1, or uses a sparser time domain pattern to send SSB and / or SIB1. The energy-saving state may be a cell that implements the aforementioned NES mechanism. For example, a cell that is transmitting discontinuously.
[0150] When the terminal has a SSB and / or SIB1 requirement, it will send 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.
[0151] In some embodiments, the base station stops sending SSB and / or SIB1 after sending one or more SSB bursts or SS bursts according to the network service load, the number of resident terminals, the service type, the time period, etc. When the base station stops sending SSB and / or SIB, it means that the base station returns to the energy-saving state.
[0152] In order to save network energy consumption, 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 terminal, the SSB and / or SIB1 corresponding to the non-anchor cell 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.
[0153] 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 sending the SSB of this cell based on the on-demand mode, periodically sending the SSB of this cell and the SSB of other cells and sending the SIB1 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 SIB1 of this cell and send SSB of this cell based on non-demand mode, periodically send SSB of this cell and SSB of other cells and send SIB1 of this cell based on non-demand mode, periodically send SIB1 of this cell and SIB1 of other cells and send SSB of this cell based on non-demand mode.
[0154] Exemplarily, non-on-demand may refer to the base station periodically transmitting the corresponding SSB or SIB1 based on semi-continuous or periodic configuration.
[0155] The above cells also have an impact on 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 on demand based on the received SIB1 information.
[0156] 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.
[0157] like Figure 1CAs shown, one SSB occupies multiple consecutive OFDM symbols in the time domain. For example, one SSB may occupy 4 symbols. SSB may include: Primary Synchronization Signals (PSS), Secondary Synchronization Signals (SSS) and PBCH information.
[0158] The New Radio (NR) system supports 5 SSB time domain transmission situations. Figure 1C The subcarrier spacing used for transmitting SSB in cases A to E shown is different, for example, some are 15kHz and some are 30kHz. Or, Figure 1C The carrier frequency range (FR) of the SSB transmission in the cases A to E shown is different. In short, the time domain patterns of these cases depend on factors such as the subcarrier spacing (SCS) of the SSB, the operating frequency, the communication format of time division multiplexing and / or frequency division multiplexing, etc.
[0159] The transmission conditions of different SSBs correspond to the number of SSBs in an SSB burst and the time domain resource positions occupied in the burst. The duration of an SSB burst is 5ms. Typically, the transmission period of SSB is 20ms. Furthermore, the base station can configure the transmission period and time domain pattern of SSB through the relevant information carried in SIB1. The maximum transmission period of SSB is 160ms.
[0160] SIB1 is scheduled by DCI format 1-0 transmitted in the common search space (Type0-(Common Serarch Space, CSS), Type0-CSS) of type 0. The synchronization signal related to Type-0 CSS and the corresponding time-frequency resource location can be indicated by the master information block (Master Information Block, MIB), and can also be configured through SIB1 or RRC signaling. Its transmission period and time-frequency resource location depend on the SSB / SIB1 multiplexing pattern and the indication information carried in the DCI format 1-0 that schedules its transmission.
[0161] The base station needs to send SIB1 periodically so that the terminal can obtain system information in a timely manner. In addition to the resource overhead caused by the SIB1 transmission itself, the control resource set (CORESET) used by the PDCCH transmission that schedules the SIB1 transmission also occupies considerable time domain resources in the time domain. SIB1 transmission can be as follows Figure 1D shown. Figure 1D Different configurations of two SSBs, SIB1 and CORESET#0 in the time domain are given.
[0162] Taking SIB1 as an example, the DCI format 1-0 is transmitted in the common search space of type 0 (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 is obtained as follows: Figure 1E shown.
[0163] 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. Finally, 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 (System Information Radio Network Temporary Identity, SI-RNTI).
[0164] Currently, SSB and SIB1 need to be sent periodically. Even if the number of terminals assigned to the base station is small or the service load is extremely low, the base station still needs to send SSB and SIB1 periodically so that the terminal 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 and obtain system information. The periodic mandatory transmission of downlink signals will undoubtedly reduce the chance of the base station entering the sleep state, increase the unnecessary consumption of energy on the base station side, and increase the operating costs of operators.
[0165] Table 1 shows the time domain resource ratio of SSB and SIB1 in different configuration / deployment scenarios. Considering that the time domain resource ratio is up to 17.14%, in this scenario, the base station side will have no chance to enter the sleep state, which greatly limits the use of energy-saving technologies on the base station side and increases the operating cost of the network.
[0166]
[0167] Table 1
[0168] like Figure 2 As shown, the embodiment of the present disclosure provides a downlink transmission method, comprising: Figure 1A The communication system shown is executed. The method may include:
[0169] S2100: The network device determines a method for sending downlink transmission to the terminal according to the type of the first cell.
[0170] In some embodiments, the network device may be an access network device. Exemplarily, the network device may include: a base station of a first cell.

In some embodiments, the first cell may be a serving cell or a neighboring cell of the terminal. In some embodiments, the serving cell of the terminal may include a primary cell and a secondary cell. Exemplarily, the first cell may be a primary cell and / or a secondary cell.
[0171] In some other embodiments, the first cell may also be a candidate cell of the terminal. The candidate cell may be a cell prepared as a serving cell. For example, the terminal may switch to the candidate cell by cell switching or cell reselection. After the terminal switches to the candidate cell, the candidate cell may be used as a serving cell after the terminal cell is replaced.
[0172] The other cells associated with the first cell may include but are not limited to: a second cell and / or a third cell.
[0173] In some embodiments, the second cell and / or the third cell may be neighboring cells of the first cell.
[0174] In some embodiments, the second cell and / or the third cell may be any cell having overlapping coverage with the first cell.
[0175] In some embodiments, the second cell and / or the third cell may be a primary cell of the first cell.
[0176] In some embodiments, the network device determines, according to a type of the first cell, a manner of sending the first transmission based on the first cell.
[0177] In some embodiments, in some embodiments, the first cell may be a first type cell or a second type cell.
[0178] In some embodiments, the first type of cells and the second type of cells may be cells of different states.
[0179] Exemplarily, the first type of cell is in a first state, the second type of cell is in a second state, and the energy consumption of the second type of cell is lower than that of the first type of cell.
[0180] Exemplarily, the first type of cells do not implement the NES mechanism, and the second type of cells implement the NES mechanism.
[0181] In some embodiments, the first type of cell and the second type of cell may be cells with different transmission mechanisms for public downlink transmission. For example, the first type of cell may be a cell that periodically transmits public downlink transmission. For another example, the second type of cell may be a cell that does not transmit public downlink transmission, or a cell that transmits public downlink transmission on demand, or the second type of cell is a cell that transmits the first transmission on behalf of other cells. In some embodiments, the public downlink transmission here is an example of the first transmission.
[0182] In some embodiments, the cell that sends the first transmission on demand may be a cell that sends the first transmission based on an on-demand mode. Exemplarily, in the on-demand mode, the second transmission sent by the terminal may trigger the cell to send the first transmission.
[0183] In some embodiments, in a scenario where the first transmission of the second type cell is sent by other cells, the other cells may periodically replace the second type cell to send the first transmission, or the other cells may send the first transmission of the second type cell based on an on-demand mode, or the other cells may send the first transmission of the second type cell based on the triggering of the second transmission of the terminal.
[0184] In some embodiments, the cell that sends the first transmission for the second type cell or the cell that sends the second transmission for the second type cell on demand may be a first type cell. Specifically, the first type cell may be an anchor cell. The second type cell may be a non-anchor cell.
[0185] In some embodiments, the first cell is a first type of cell, and the first cell transmits the first transmission based on semi-static configuration and / or periodic configuration and / or indication signaling.
[0186] In some embodiments, the first cell is a first type cell, and a terminal in the first cell receives a first transmission based on a semi-static configuration and / or a periodic configuration and / or an indication signaling.
[0187] In some embodiments, the first cell is a second type cell, and the first cell transmits the first transmission based on an on-demand mode.
[0188] In some embodiments, transmitting the first transmission in the on-demand mode in the second type cell includes at least one of the following: the base station autonomously determines whether to transmit the first transmission based on the cell communication status; the base station determines whether to transmit the first transmission based on the second transmission sent by the terminal.
[0189] In some embodiments, the first cell is a second type cell, and a terminal in the first cell cannot receive a 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.
[0190] 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. In some embodiments of the first aspect, if a terminal in the first cell cannot receive the first transmission, the terminal determines that the first cell is a second-category cell. Exemplarily, if the terminal in the first cell cannot receive the first transmission and the failure to receive the first transmission is not caused by a link failure of the terminal, the terminal determines that the first cell is a second-category cell.
[0191] In some embodiments, 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.
[0192] Exemplarily, under the condition that the terminal determines that the first cell is a second-category cell, if the terminal in the first cell cannot receive the first transmission, the terminal determines that the reception failure of the first transmission is caused by a link failure of the terminal.
[0193] In some embodiments, the public downlink transmission may include: a cell-level downlink signal and / or downlink channel information.
[0194] Exemplarily, in some embodiments, public downlink transmission may include but is not limited to at least one of the following: SSB; System Information Block (SIB), exemplarily, the SIB may include but is not limited to SIB1 and / or SIBn, where n may be any positive integer greater than or equal to 2; Physical Downlink Control Channel (PDCCH) information and / or Physical Downlink Shared Channel (PDSCH) information.
[0195] In some implementations, the first type of cells may be anchor cells and the second type of cells may be non-anchor cells.
[0196] In some embodiments, the first type of cell and the second type of cell may be cells with different transmission mechanisms for the first transmission. The first type of cell sends the first transmission based on a semi-static configuration and / or a periodic configuration. For example, the first type of cell sends the first transmission with a semi-static period according to the semi-static configuration. For example, the first type of cell sends the first transmission with a configured period according to the periodic configuration.
[0197] For the first type of cell, the terminal can receive the first transmission at a corresponding time according to the semi-static configuration and / or periodic configuration, and the terminal does not need to actively request the network side to send the first transmission.

[0257] If a cell is associated with SIB1 or CORESET#0 or type 0 physical downlink control channel common search space (Type0 Physical Downlink Control Channel Common Search Space, PDCCH CSS), it means that the cell will send SIB1. If a cell is not associated with SIB1, CORESET#0 and type 0 physical downlink control channel common search space (Type0 Physical Downlink Control Channel Common Search Space, PDCCH CSS), it can be considered that the cell will not send SIB1.
[0258] In some embodiments, the cell is associated with a Type 0 Physical Downlink Control Channel Common Search Space (PDCCH CSS), which means that the cell is considered to be associated with a CORESET corresponding to the Type 0 Physical Downlink Control Channel Common Search Space (PDCCH CSS), which means that the cell is considered to be associated with SIB1.

[0264] In some other embodiments, the first information indicates a possible cell type of the first cell, and the actual type of the first cell may need to be determined in combination with the second information and / or the third information. Exemplarily, when the first information indicates a possible type of the first cell, the type of the first cell may be accurately determined in combination with the first information and the second information.
[0265] Exemplarily, the first information and the second information may come from the same cell or from different cells. For example, the first information may come from an anchor cell, and the second information may come from a non-anchor cell, in which case the first information and the second information come from different cells. The anchor cell may be the first cell, and the non-anchor cell may be the second cell. Alternatively, the anchor cell may be the second cell and the non-anchor cell may be the first cell. For another example, the first information and the second information may both come from the anchor cell, for example, the first information and the second information are both sent by the second cell, and the second information is used to configure the second transmission of the first cell.

[0267] In some embodiments, the first information indicates that the first cell is a second type cell and the second information indicates that the value of the subcarrier offset Kssb of the first cell does not meet the first condition, and the current scenario is determined to be an error scenario.
[0268] In some embodiments, if the terminal determines that the scenario is an incorrect scenario, the terminal cannot determine the type of the corresponding cell, or the terminal abandons the type judgment of the corresponding cell, or the terminal determines that the type of the cell is incorrect, or the terminal still determines that the first cell is a second type cell when the value of the subcarrier offset Kssb of the first cell does not meet the first condition, or the terminal determines that the cell is a cell that transmits the second transmission on demand, or the terminal determines that the cell is an existing legacy cell.
[0269] In some embodiments, the terminal may determine the frequency domain position of the CRB grid of the corresponding cell based on the first parameter, and the frequency domain position of the CRB grid may be used by the terminal to determine the frequency domain position of the corresponding CORESET#0, and / or, the frequency domain position of the CRB grid may be used by the terminal to determine the frequency domain position of the corresponding SIB1. In some embodiments, the first information and the third information may be used together to determine whether the first cell is a second type of cell that sends a first transmission based on an on-demand mechanism, or a second type of cell that does not send a first transmission. For example, if the first information indicates that the first cell is a second type of cell, and the terminal receives the third information for the first cell sent by the network device, it may indicate that the first cell is a second type of cell that sends a first transmission based on an on-demand mechanism, otherwise it may indicate that the first cell is a second type of cell that does not send a first transmission.
[0270] In some embodiments, the first parameter may be another subcarrier offset parameter Should The value range of can be a positive integer greater than or equal to 0 and less than 24.

For another example, the third set may include an odd number of alternative values of Kssb, and the fourth set may include an even number of alternative values of Kssb. In an example, the alternative values of Kssb contained in the third set are all greater than the alternative values of Kssb contained in the fourth set. For another example, the alternative values of Kssb contained in the fourth set are all greater than the alternative values of Kssb contained in the third set. In some embodiments, the alternative values of Kssb included in the third set and the fourth set are predefined, for example, predefined by a protocol. In other embodiments, the alternative values of Kssb included in the third set and the fourth set are configured by a network device. In other embodiments, the alternative 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.
[0325] In some embodiments, the frequency range used by the first cell is FRa, then Kssb may be jointly indicated by the PBCH information and the MIB. For example, ssb-SubcarrierOffest is jointly indicated using one bit of the PBCH information and the indication bit of ssb-SubcarrierOffest in the MIB. In some embodiments, the frequency range used by the first cell is FRb, then Kssb may be separately indicated by the indication bit of ssb-SubcarrierOffest in the MIB. In some embodiments, FRa and FRb are different. Exemplarily, Fra is located in frequency range 1 (Frequency Range 1, FR1), and FRb is located in frequency range 2 (FrequencyRange 1, FR2).
[0326] In some embodiments, according to the type of the first cell, determining the verification method of the physical broadcast channel PBCH information of the first cell includes at least one of the following: if the first cell is a first type cell, determining that the PBCH information of the first cell has a first verification code; if the first cell is a first type cell, determining that the PBCH information of the first cell has a second verification code. In some embodiments, different verification methods may correspond to different verification sequences, different verification algorithms, etc. In this way, the type of the first cell can be implicitly indicated by different verification methods of the PBCH information.
[0327] In some embodiments, the type of the first cell is determined according to a verification method of the PBCH information of the first cell, including at least one of the following: a first verification code used by the PBCH information of the first cell is generated based on a first verification algorithm, and the first cell is determined to be a first type of cell; a second verification code used by the PBCH information of the first cell is generated based on a second verification algorithm, and the first cell is determined to be a second type of cell. In some embodiments, the first verification algorithm and the second verification algorithm may be different cyclic redundancy check (CRC) algorithms. Exemplarily, the verification method may refer to a method of calculating CRC in Downlink Physical-Layer processing. 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. For example, the first check algorithm can be g CRC24C (D). Exemplarily, the second verification algorithm may be g CRC24A (D) or g CRC24B (D) In some embodiments, the first check algorithm is a CRC check algorithm for PBCH information in the related art. In some embodiments, the second check algorithm is different from the first check algorithm.
[0328] The above is merely an example of the verification method of the PBCH information of the first cell, and the specific implementation is not limited to the above example.
[0329] In some embodiments, according to the type of the first cell, the scheduling instruction and / or the scheduling content of the scheduling instruction for sending the first transmission in the first cell are set, including at least one of the following: the first cell is a second-type cell, and the scheduling instruction is not sent N times; N is a positive integer; exemplarily, the first cell is a second-type cell, and the scheduling instruction is not sent N times in succession at the reception timing of the scheduling instruction of the first transmission; N is a positive integer; the first cell is a second-type cell, and the scheduling instruction for scheduling the first transmission is not sent X times; X is a positive integer, exemplarily, the first cell is a second-type cell, and the scheduling instruction for scheduling the first transmission is not sent X times in succession at the reception timing of the scheduling instruction of the first transmission. In some embodiments, the first cell is a second-type cell, and the scheduling instruction received by the first cell at the reception timing of the scheduling instruction capable of scheduling the first transmission does not schedule the first transmission X times; X is a positive integer. Exemplarily, the scheduling instruction of the SIB may be downlink control information (DCI). In some embodiments, if the first cell is a second-type cell, the first cell does not send DCI N times in succession or does not send DCI for scheduling SIB for X times in succession during the listening time of the DCI capable of scheduling the SIB.
[0330] In some embodiments, N and X may be any positive integers, which may be configured or predefined by the network. In some embodiments, N and X may be equal or unequal.

In some embodiments, the first cell is a second type cell, and no scheduling instruction is sent for scheduling the first transmission X times within the first time window. The first time window may be determined by network signaling configuration or a predefined method. The predetermined method includes but is not limited to protocol agreement. Exemplarily, the starting position of the first time window is the period of the DCI of the terminal currently blindly checking the scheduling of the first transmission. Exemplarily, the starting position of the first time window is the period of the terminal currently receiving the first transmission based on the configuration.
[0332] In some embodiments, the first cell is a first type cell, and it is determined to send the first transmission according to the configuration of the first transmission. In some embodiments, the first cell is a second type cell, and it is determined to send the first transmission on demand. For example, the first cell is a second type cell, and it is determined to send the first transmission according to the needs of the first cell itself. For another example, the first cell is a second type cell, and it is determined to send the first transmission based on the triggering of the second transmission sent by the terminal. In some embodiments, the first cell is a second type cell, and it is determined not to send the first transmission.
[0333] In some embodiments, the network device determines whether to send configuration information for the second transmission based on the type of the first cell, which may include at least one of the following: when the first cell is a first type cell, determining not to send configuration information for the second transmission for the first cell; when the first cell is a second type cell that sends the first transmission based on an on-demand mode, determining to send configuration information for the second transmission for the first cell; when the first cell is a second type cell that does not send the first transmission, determining not to send configuration information for the second transmission for the first cell.
[0334] In some embodiments, the second transmission may be an uplink transmission that triggers the first cell to send the first transmission. In some embodiments, the second transmission may be a wake-up signal (WUS).

[0336] In some embodiments, the value of the first parameter indicated by the third information is at least used to determine the frequency domain position of the common resource block CRB of the second type of cell. Further, the frequency domain position of the CRB can be used to determine the frequency domain position of CORESET#0.
[0337] In some embodiments, the value of the first parameter indicated by the third information can be further used to determine whether the corresponding second-type cell is a cell that sends the first transmission by an on-demand mechanism or a cell that does not send the first transmission; for example, if the value of the first parameter is greater than 24, the corresponding second cell can be considered to be a cell that does not send the first cell, otherwise the corresponding second-type cell can be considered to be a cell that sends the first transmission by an on-demand mechanism.
[0338] In some embodiments, when the first cell is a first type cell, it is determined not to send the third information. In some embodiments, when the first cell is a second type cell that sends the first transmission based on an on-demand mechanism, it is determined to send the third information. In some embodiments, when the first cell is a second type cell based on not sending the first transmission, it is determined not to send the third information.
[0339] In some embodiments, the third information may be included in the configuration information of the second transmission. Alternatively, the third information and the configuration information of the second transmission are carried in the same IE or the same message. In some embodiments, the configuration information of the second transmission may include but is not limited to the configuration information of the WUS.

In some embodiments, it is determined whether to send the third information according to the value range of Kssb indicated by the second information. In some embodiments, for a cell using FR1, when the value of Kssb indicated by the second information is greater than 23, it is determined to send the third information, otherwise it is determined not to send the third information. In some embodiments, for a cell using FR2, when the value of Kssb indicated by the second information is greater than 11, it is determined to send the third information, otherwise it is determined not to send the third information.
[0341] S2102: The terminal determines the type of the first cell.
[0342] In some embodiments, the terminals may be divided into two types, namely, first type terminals and second type terminals.
[0343] 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.
[0344] In some embodiments, S2102 may include: the first type terminal determines the type of the first cell.
[0345] In some embodiments, the second type terminal may skip the step of determining the type of the first cell.
[0346] 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.
[0347] In some embodiments, the first cell is a first type cell or a second type cell. For the related description of the first type cell and the second type cell here, refer to the related description of step S2100.
[0348] In some embodiments, the manner in which the terminal determines the type of the first cell can be divided into two categories: the first category: determining the type of the first cell according to a predefined method; the second category: the terminal determines the type of the first cell according to downlink transmission on the network side.
[0349] 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.
[0350] In some embodiments, the cell attributes may include: cell status, cell transmission mode and / or sent downlink transmissions of the cell.
[0351] The cell state may include: whether the cell is in an energy-saving state, and 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 SSB and / or SIB is not sent, or a state in which SSB and / or SIB is sent on demand.
[0352] In some embodiments, if the first cell sends SSB and / or SIB periodically, the first cell is a first type cell, otherwise it may be a second type cell. In some embodiments, if the first cell sends SSB and / or SIB periodically on demand, the first cell is a second type cell, otherwise it may be a second type cell. In other embodiments, the network device determines the type of the first cell based on the frequency range used by the first cell, for example, the frequency band to which it belongs. At this time, the terminal can determine whether the first cell is a first type cell or a second type cell according to a predefined method without receiving information from the network device. Exemplarily, the terminal determines the type of the first cell based on one or more downlink transmissions sent by the network device in S2101. Again exemplarily, the first type terminal determines the type of the first cell based on one or more downlink transmissions sent by the network device in S2101.
[0353] In the embodiment of the present disclosure, there are multiple ways to determine the type of the first cell according to the downlink transmission on the network side. Several optional ways are provided below:
[0354] In some embodiments, the type of the first cell is determined according to the configuration information of the second transmission. For example, the type of the first cell may be determined according to the purpose of the configuration information of the second transmission.
[0355] In some embodiments, the second transmission is used to trigger the sending of the first transmission. Since the second transmission is the first transmission used to trigger the sending of the second type of cell. If the terminal receives the configuration information of the second transmission for the first cell, it can be equivalent to the network side implicitly indicating that the first cell is a second type of cell. For example, the terminal can receive the configuration information of the second transmission from the first cell or the neighboring cell of the first cell. 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. 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 type of cell. 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, 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 type of cell, otherwise it can be a first type of cell. In some embodiments, the configuration information is used for the terminal to send the second transmission, which indicates that the first cell is a second type of cell. Or, if the configuration information is not used for the terminal to send the second transmission, it indicates that the first cell is a first type of cell. That is, the type of the first cell can be distinguished according to whether the second transmission configuration information is configured for a cell.
[0356] 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.
[0357] In some embodiments, if the terminal does not receive any configuration information corresponding to the second transmission for sending a triggering first cell to send a first transmission, and / or the terminal can receive the first transmission based on the corresponding first transmission configuration information, then the terminal determines that the first cell is a first type cell. In some embodiments, the second transmission may be referred to as a wake-up signal (WakeUp Signal, WUS). The configuration information of the second transmission may include configuration information of the WUS.
[0358] In some embodiments, the configuration information is used to send a WUS that triggers the first cell to send a first transmission, indicating that 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, it indicates that the first cell is a first-category cell. That is, the type of the first cell can be distinguished based on the configuration information of the WUS.
[0359] 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.
[0360] 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.
[0361] 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.
[0362] The cell receiving the second transmission may be a corresponding second type cell or a cell associated with the second type cell. For example, the cell associated with the second type cell may include: a neighboring cell of the second type cell, a primary cell associated with the second type cell, or a secondary cell associated with the second type cell.
[0363] 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.
[0364] In some embodiments, the terminal determines the cell identity (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 transmission configuration information to determine whether the second transmission configuration information corresponds to the first cell. If the second transmission 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.
[0365] In some embodiments, the second transmitted configuration information is carried in the cell configuration of the first cell, or the second transmitted configuration information is carried in the cell configuration of the third cell. 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.
[0366] In some embodiments, the third cell is a primary cell of the terminal and the first cell is a secondary cell of the terminal. In some embodiments, the third cell is a secondary cell of the terminal and the first cell is a primary cell of the terminal. For example, the third cell may be a primary cell of the terminal, and in the cell configuration of the primary cell, the configuration information of the second transmission of one or more secondary cells of the terminal may be carried, so that the corresponding secondary cell is a second type cell.
[0367] In some embodiments, the configuration information of the second transmission is carried in the cell configuration of the first cell. For example, if the first cell is a secondary cell, the cell configuration may include but is not limited to the secondary cell configuration (ScellConfig). For another example, if the first cell is a serving cell, the cell configuration may include but is not limited to the serving cell configuration (servingCellConfig).
[0368] In some embodiments, the type of the first cell is determined according to the cell configuration of the first cell. In some embodiments, the cell configuration of the first cell may explicitly or implicitly indicate the type of the first cell. One or more bits of explicit indication are carried in the cell configuration of the first cell to indicate the type of the first cell. In other embodiments, whether the cell configuration carries a configuration of a second transmission to implicitly indicate whether the first cell is a second type cell. In some embodiments, whether the cell configuration of the first cell includes a state of a first indication domain is used to implicitly indicate the type of the first cell. In some embodiments, the cell configuration of the first cell includes a first indication domain, determining that the first cell is a first type cell, and the cell configuration of the first cell does not include the first indication domain, determining that the first cell is a second type cell. In other embodiments, the cell configuration of the first cell includes a first indication domain, determining that the first cell is a second type cell, and the cell configuration of the first cell does not include the first indication domain, determining that the first cell is a first type cell.
[0369] 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.
[0370] 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.
[0371] In some embodiments, the first indication field has a first value, indicating that the first cell is a cell of the first type. The first indication field has a second value, indicating that the first cell is a cell of the second type.
[0372] In some embodiments, the cell configuration includes: a secondary cell ScellConfig configuration.
[0373] In some embodiments, the type of the first cell is determined according to a master information block MIB of the first cell.
[0374] 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.
[0375] In some embodiments, the MIB may include one or more indication bits. One way is to multiplex indication bits indicating other information to indicate the type of the first cell. Another way is to use idle bits in the MIB to indicate the type of the first cell.
[0376] In some embodiments: the type of the first cell is determined according to 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.
[0377] 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.
[0378] 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 a terminal receives such a 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.
[0379] 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.
[0380] 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.
[0381] 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.
[0382] 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.
[0383] 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. Exemplarily, the type of the first cell may be directly or indirectly indicated by the cell barred indication bit.
[0384] 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. Exemplarily, the common subcarrier spacing subcarrierSpacingCommon indication bit can directly or indirectly indicate the type of the first cell.
[0385] In some embodiments, the value of at least one indicator bit in the MIB of the first cell is within the first set, indicating that the first cell is a first type cell. In some embodiments, the value of at least one indicator bit in the MIB of the first cell is within the second set, indicating that the first cell is a second type cell. Exemplarily, the type of the first cell is determined according to the value of the synchronization signal broadcast block-subcarrier spacing offset ssb-SubcarrierOffest indicator bit in the MIB of the first cell, including: the value of the ssb-SubcarrierOffest indicator bit in the MIB of the first cell is within the first set, determining that the first cell is a first type cell; the value of the ssb-SubcarrierOffest indicator bit in the MIB of the first cell is within the second set, determining that the first cell is a second type cell.
[0386] In some embodiments, both the first set and the second set may include one or more ssb-SubcarrierOffest alternative values. The first set corresponds to the first type of cell, and the second set corresponds to the second type of cell. At this time, the terminal can determine the type of the first cell according to the set of bit values indicated by the ssb-SubcarrierOffest indicator bit.
[0387] In some embodiments, the values of the first set and the second set may be predefined by network configuration or protocol agreement. In some embodiments, the values in the first set and the second set may be configured by a network device, or may be predefined by protocol agreement. 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. Exemplarily, the first set contains 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 greater than the values of the second set. Exemplarily, the values of the second set correspond to the reserved state, and the values of the first set correspond to other states other than the reserved state. Exemplarily, taking the determination of CORESET#0 corresponding to SIB1 based on Table 2 as an example, the first set corresponds to indexes 0, 1, 2, ..., 13 in Table 2, and the second set corresponds to indexes 14, 15 in Table 2. 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.
[0388] 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. 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. In some embodiments, according to the value of the cell barred indication (CellBarred) indication bit in the MIB of the first cell, according to the type of the first cell. In some embodiments: according to the value of the intraFreqReselections indication bit in the MIB of the first cell, the type of the first cell is determined. Exemplarily, the type of the first cell can be directly or indirectly indicated by the intraFreqReselections indication bit of the intraFreqReselections.
[0389] In some embodiments, the type of the first cell is determined based on the physical broadcast channel (PBCH) information of the first cell. In some embodiments, the type of the first cell is determined based on the reserved bits of the PBCH information of the first cell. In some embodiments, the type of the first cell is determined based on the reserved bits of the PBCH information of the first cell. is the first value, and the reserved bit is the first bit.

The PBCH information may be any information carried on the PBCH. In the embodiments of the present disclosure, the first cell may indicate the type of the first cell through the PBCH information.
[0391] In some embodiments, the type of the cell is determined according to the value of Kssb. When Kssb belongs to the first set, the cell associated with the SSB is a first type of cell. When Kssb belongs to the second set, the cell associated with the SSB is a second type of cell. The first set can be determined based on signaling or a predefined method. 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. 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. In some embodiments, the second set is a Kssb with an even value, and the first set is a Kssb with an odd value.

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. In some embodiments, in the FR1 scenario, the second set is a Kssb equal to 30, and in the FR2 scenario, the second set is a Kssb equal to 14. 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. In some embodiments, the terminal determines Kssb according to network signaling, and determines the subcarrier spacing (k SSB-offset ). In some embodiments, the network signaling may be MIB, or MIB and PBCH information. SSB-offset Equal to the lowest subcarrier of SSB and N CRB The lowest subcarrier offset, N CRBis the lowest CRB that has frequency domain intersection with CRB. 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 to be equal to k SSB-offset = Kssb. In some embodiments, Kssb is greater than or equal to a specified value, and the subcarrier spacing k can be determined based on Kssb. SSB-offset . Exemplarily, the specified 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. Exemplarily, the specified 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. Exemplarily, under the condition that Kssb is greater than or equal to the specified value, the terminal determines the subcarrier spacing k based on a predefined rule. SSB-offset , predefined rules include but are not limited to: k SSB-offset =Kssb-N1; k SSB-offset =Kssb mod M1. N1 and M1 are determined based on signaling instructions, and can also be determined based on predefined rules. Exemplarily, N1 is equal to 9 or 10; Exemplarily, M1 is equal to 24 (corresponding to FR1), and M1 is equal to 12 (corresponding to FR1 or corresponding to FR2). 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-class cell, and the frequency domain position of the CRB is determined based on Kssb. The specific method is as follows: The terminal determines the lowest subcarrier of the SSB and N based on Kssb-offset. CRB The lowest subcarrier offset, N CRB The lowest CRB that has frequency domain intersection with the CRB. Kssb-offset = Kssb-9, or Kssb-offset = Kssb mod24. It can be applied to the scenario of Kssb = 30, and can also be applied to other Kssb value scenarios. Exemplarily, for a terminal that supports network energy saving, under the condition that the cell is determined to be a second-class cell based on signaling, the corresponding pdcch-ConfigSIB1 can be read to determine the corresponding SearchSpace#0 or CORESET#0.
[0392] In some embodiments, the type of the first cell is determined based on the MIB and PBCH information of the first cell. 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 indication bit of the MIB and PBCH information.
[0393] 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.
[0394] Exemplarily, the maximum value indicated by the indication bit of Kssb is small, and only the indication bit of MIB can be used. When the maximum value indicated by the indication bit of Kssb is large, the indication bits of MIB and PBCH information can be occupied at the same time. At this time, 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 way for MIB and PBCH information to jointly indicate the type of the first cell.
[0395] 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 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 type 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 type cell.
[0396] 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 performed based on ssb-SubcarrierOffest in MIB and other bits in PBCH.
[0397] 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.
[0398] For example, the third set may include even candidate values for Kssb, and the fourth set may include odd candidate values for Kssb.
[0399] For another example, the third set may include odd candidate values of Kssb, and the fourth set may include even candidate values of Kssb.
[0400] 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.
[0401] 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.
[0402] 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.
[0403] In other embodiments, the alternative values of Kssb included in the third set and the fourth set are configured by a network device. In other embodiments, the alternative values of Kssb included in the third set and the fourth set are determined according to the frequency range (Frequency Range, FR) used by the first cell. In some embodiments, the type of the first cell is determined according to the verification method of the PBCH information of the first cell. In some embodiments, different verification methods may correspond to different verification sequences, different verification algorithms, etc. In this way, the type of the first cell can be implicitly indicated by different verification methods of the PBCH information.
[0404] In some embodiments, determining the type of the first cell according to the verification method of the PBCH information of the first cell includes at least one of the following: the PBCH information of the first cell is successfully verified using a first verification algorithm, and the first cell is determined to be a first type of cell;
[0405] The PBCH information of the first cell is successfully verified using the second verification code algorithm, and the first cell is determined to be a second type cell. In some embodiments, the first verification algorithm and the second verification algorithm can both be cyclic redundancy check (CRC) verification algorithms.
[0406] 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.
[0407] 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 according to the reception status of the first transmission.
[0408] For example, after camping on the first cell, the terminal may first regard the first cell as a first-type cell and monitor multiple cycles of the first transmission. If the first transmission is not received, the first cell may be considered as a second-type cell. Otherwise, the first cell may be considered as a first-type cell.
[0409] 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.
[0410] 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.
[0411] 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.
[0412] In some embodiments, the multiple periods may be periods continuously distributed in the time domain, or specified specific periods.
[0413] In some embodiments, the terminal fails to receive the first transmission for M consecutive times at the reception opportunity of the first transmission, and 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.
[0414] In some embodiments, the value of M may be configured by the network or determined based on a predefined method.
[0415] 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.
[0416] In some embodiments, the terminal failing to receive the first transmission M times in a row at the reception timing of the SIB 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 This is a time domain configuration of SSB and / or SIB. It can be seen that SSB and SIB may have one or more reception opportunities in one time slot.
[0417] For example, after the terminal resides in the first cell, if the terminal fails to monitor the SSB for M consecutive SSB reception opportunities, the first cell can be considered as a second-type cell.
[0418] For another example, after the terminal resides in the first cell, if the terminal does not receive SIB1 in M consecutive SIB1 reception opportunities, the first cell can be considered as a second type cell.
[0419] In some embodiments, the reception timing 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 timing for SIB1. A second time window is configured for SSB. One second time window may be a reception timing for SSB.
[0420] In some embodiments,
[0421] The type of the first cell is determined according to a reception status of the terminal in the first cell with respect to the scheduling instruction of the first transmission.
[0422] In some embodiments, if the terminal fails to receive the scheduling instruction N times in a row at the reception timing of the scheduling instruction of the first transmission, it determines that the first cell is a second type cell; N is a positive integer.
[0423] 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, it is determined that the first cell is a second-category cell; X is a positive integer.
[0424] Exemplarily, the scheduling instruction of the SIB may be downlink control information (DCI).
[0425] 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.
[0426] In other embodiments, if 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, it 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.
[0427] In some embodiments, both N and X may be any positive integers and may be configured or predefined by the network.
[0428] In some embodiments, N and X may be equal or unequal.
[0429] In some embodiments, if the terminal does not monitor the DCI scheduling SIB for 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-type cell, otherwise the first cell can be considered as a first-type cell.
[0430] In some embodiments, if 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.
[0431] 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.
[0432] In some embodiments, the first time window starts with the current blind detection period of the first transmission where the terminal is located, and N consecutive blind detection periods of the first transmission.
[0433] In some embodiments, the first time window starts with the current first transmission period in which the terminal is located, and N consecutive first transmission periods.
[0434] In some embodiments, the first sub-type cell is an on-demand cell, and the second sub-type cell is a cell that is prohibited from terminal access.
[0435] In some embodiments, the terminal stores status information of the cell.
[0436] In some embodiments, after receiving the second transmission configuration information corresponding to the cell, the cell is determined to be a first sub-type cell; otherwise, the cell is determined to be a second sub-type cell.
[0437] 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.
[0438] 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-category cell; the terminal receives the first transmission of the first cell from the second cell, and determines that the first cell is a second-category cell.
[0439] In some embodiments, some cells of the first category may replace cells of the second category to send the first transmission.
[0440] 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.
[0441] 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.
[0442] 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, so that when the terminal receives the first transmission sent by the second cell, it knows to which cell the corresponding first transmission belongs.
[0443] In some embodiments, a terminal in a first cell receives a first transmission based on a semi-static configuration and / or a periodic configuration and / or an indication signaling, and the first cell is a first type of cell;
[0444] In some embodiments, the first cell is a second type cell, and the first cell transmits the first transmission based on an on-demand mode.
[0445] In some embodiments, the on-demand mode transmission of the first transmission by the second type of cell comprises at least one of the following:
[0446] The base station autonomously determines whether to transmit the first transmission based on the cell communication status;
[0447] The base station determines whether to transmit the first transmission based on the second transmission sent by the terminal.
[0448] In some embodiments of the first aspect, a terminal in a first cell is unable to receive a 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 by the configuration and / or indication signaling within a second time range, and the first cell is a second type cell.
[0449] In some embodiments, the first cell is a second type cell and the first cell does not transmit the first transmission.
[0450] In some embodiments, a terminal in the first cell cannot receive the first transmission, and the cell is a second type cell.
[0451] In some embodiments, whether the first cell is a second type of cell is determined based on the configuration information of the second transmission.
[0452] Exemplarily, the second transmitted configuration information is applied to the first cell, and the first cell is determined to be a second type cell.
[0453] In some embodiments, the second transmission may be received by the first cell itself, or may be received by other cells instead of the first cell. In either case, if the second transmission is directed to the first cell (ie, related to the first cell), it can be determined that the first cell may be a second type cell.
[0454] Exemplarily, when there is no configuration information for the second transmission of the first cell, under the condition that the first cell is a second type cell, it is determined that the first cell is a second type cell that does not send the first transmission.
[0455] Exemplarily, when there is configuration information for the second transmission of the first cell and / or corresponding indication information is received, the indication information indicates that other cells replace the first cell to receive the second transmission or replace the first cell to send the first transmission, and the first cell is determined to be a second type of cell in which the other cells replace the first transmission. Exemplarily, the indication information can be configuration information or other information, such as system information, RRC, MAC CE or DCI, etc., and the present invention is not limited to this.
[0456] Also exemplarily, when there is configuration information for the second transmission of the first cell and / or corresponding indication information is received, the indication information indicates that the second transmission is received by the first cell itself or the first transmission is sent by the first cell itself, and the first cell is determined to be a cell that sends the first transmission in an on-demand mode. Exemplarily, the indication information may be configuration information or other information, such as system information, RRC, MAC CE or DCI, etc., and the present invention is not limited to this.
[0457] In some embodiments, based on one or more of the aforementioned first information, second information and third information, it is determined which type of second type cell the first cell is. The specific determination method can be explicitly or implicitly indicated by the first information, second information and third information.
[0458] In some embodiments, the type of the first cell is determined based on whether configuration information of the second transmission is received, and the second transmission is used to trigger the sending of the first transmission.
[0459] Exemplarily, after receiving second transmission configuration information for the first cell, it is determined that the first cell is a second type cell.
[0460] Exemplarily, after receiving configuration information for the second transmission of the first cell, it is determined that the first cell is a second type cell that sends the first transmission based on an on-demand mechanism.
[0461] In some embodiments, when it is determined that the first cell is a second type cell based on the configuration information of the second transmission, it can be further determined based on the configuration information of the second transmission that the first cell is a second type cell that sends the first transmission based on an on-demand mode, or a second type cell that does not send the first transmission, or a second type cell that sends the first transmission by other cells.
[0462] In some embodiments, the first cell is determined to be a first type of cell or a second type of cell or the first cell is a specific type of the second type of cell (for example, a second type of cell that sends a first transmission based on an on-demand mode, or a second type of cell that does not send a first transmission, or a second type of cell that sends a first transmission on behalf of other cells) based on one or more methods such as a predefined method, based on a reception condition of the first transmission of the first cell, based on whether the reception condition of the first transmission of the first cell is received from the second cell, etc.
[0463] In summary, in the embodiments of the present disclosure, all methods for determining whether the first cell is a first type cell or a second type cell or a specific type of the second type cell can also be used to determine the specific type of the second type cell to which the first cell belongs.
[0464] Specifically, whether the first cell is a second-category cell may be determined according to the method provided in any one of the aforementioned embodiments.
[0465] In some embodiments, when a second type of cell is determined, it is also possible to determine whether the first cell is a second type of cell that sends a first transmission based on an on-demand mechanism, a second type of cell that does not send a first transmission, or a second type of cell in which other cells send the first transmission, based on whether configuration information for a second transmission for the first cell is received.
[0466] Exemplarily, when it is determined that the first cell is a second-category cell and configuration information for the second transmission of the first cell is not received, the first cell is determined to be a second-category cell that does not send the first transmission. When it is determined that the first cell is a second-category cell and configuration information for the second transmission of the first cell is received, the first cell is determined to be a second-category cell that sends the first transmission based on an on-demand mechanism, or a second-category cell in which the first transmission is sent by other cells.
[0467] S2103: The terminal determines a method for receiving the first transmission. In some embodiments, the terminal determines a method for receiving the first transmission based on the first cell.
[0468] In some embodiments, the terminal determines the manner based on receiving the first transmission according to the type of the first cell.
[0469] In some embodiments, the terminal determines, according to a type of the first cell, a manner of receiving the first transmission based on the first cell.
[0470] 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.
[0471] Exemplarily, the configuration of the first transmission may include: semi-static configuration and / or periodic configuration.
[0472] In some embodiments, the first cell is a first type of cell, and it is determined to receive the first transmission according to the configuration of the first transmission when camping in the first cell.
[0473] In some embodiments, if the first cell is a first type of cell, the terminal may continue to determine the manner of receiving the first transmission from the network side according to a condition in which the terminal receives the first transmission based on the first cell.
[0474] 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 because the link failure of the terminal in the first cell caused the failure of the first transmission reception. 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.
[0475] Link recovery here may include but is not limited to beam recovery.
[0476] 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.
[0477] It is worth noting that link recovery and connection reestablishment are different processes for the terminal to maintain communication with the first cell.
[0478] 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 judges 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.
[0479] If the first cell is a first type cell, it is determined to perform cell switching or cell reselection.
[0480] 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.
[0481] In some embodiments, if the first cell is a first type cell and the measurement result of the first cell is less than a specified threshold, it is determined to perform cell switching or cell reselection.
[0482] 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.
[0483] 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 cell selection, cell switching or cell reselection processes.
[0484] In some embodiments, the first cell is a second type cell, and determining triggers the first cell to send the first transmission.
[0485] 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.
[0486] 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.
[0487] 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 according to whether the terminal has a configuration for the second transmission of the first cell.
[0488] 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.
[0489] Exemplarily, the first cell is a second type cell, and the first cell sends a first transmission according to a demand that the first cell is searched by the terminal. In this case, the network side does not need to provide the terminal with a configuration of a second transmission corresponding to the first cell.
[0490] Also exemplarily, if 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, 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.
[0491] 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.
[0492] 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:
[0493] a second transmission sent to the terminal or receiving a second transmission sent by a fourth cell;
[0494] The first transmission is sent to the terminal based on the second transmission.
[0495] In some embodiments, the fourth cell may be a neighboring cell of the first cell. In some embodiments, the fourth cell may be a primary cell of the first cell. In some embodiments, the fourth cell and the first cell may be any cells with overlapping coverage.
[0496] In some 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.
[0497] 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 second type cell, the terminal determines that the cell may be in a state of sending the first transmission on demand. Under the condition that the terminal needs the first transmission, the terminal sends a request message to request the transmission of the first transmission information.
[0498] In some embodiments, a first parameter is determined according to the third information; and a frequency domain position of a common resource block CRB of a second type of cell that sends a first transmission in an on-demand mode is determined according to the first parameter. The frequency domain position of the CRB can be used by the terminal to determine the frequency domain position of CORESET#0, and based on CORESET#0, monitor the reception of downlink control information (Downlink Control Information, DCI) of the scheduling SIB1 of the second type of cell that sends the first transmission based on the on-demand mechanism. If the DCI is successfully received, SIB1 is received according to the resource position scheduled by the DCI.

[0500] S3101: Receive downlink transmission.
[0501] In some embodiments, the terminal receives downlink transmission from the network side.

[0509] In some embodiments, the first type of terminal determines the manner of receiving the first transmission based on the first cell according to the type of the first cell.
[0510] In some embodiments, after the second type cell determines that the first cell is a second type cell, the terminal resides on other cells through processes such as cell reselection and / or cell switching, and receives the first transmission from the other cells.
[0511] For example, any optional embodiment of the terminal determining the manner of receiving the first transmission can be referred to in Figure 2 S2103 of the corresponding embodiment.
[0512] It is worth noting that: S3101 may be an optional step. The terminal may determine the type of the first cell according to a predefined method such as protocol agreement without receiving downlink transmission from the network side. In this case, S3101 may be omitted.

[0521] For terminals that support network energy-saving technology, whether the cell is an on-demand SSB / SIB1 cell or an SSB / SIB1-less cell is determined based on a predefined method or indication signaling, and the corresponding SSB / SIB1 reception method is determined.
[0522] Exemplarily, an SSB / SIB1-less cell may be a cell that does not send SSB and / or SIB.
[0523] 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 other cells other than the second type cell.
[0524] Terminal side:
[0525] The terminal supporting network energy saving determines the type of the cell based on the following scheme, and determines whether to receive downlink transmission based on the types of different cells. The downlink transmission may include downlink signals and / or downlink channel information. The downlink transmission includes at least SSB and / or SIB1.
[0526] 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.
[0527] The terminal determines the cell as an on-demand SIB1 / SSB cell according to a predefined method.
[0528] The terminal does not receive SIB1 / SSB within a first time window. The first time window is determined based on a signaling indication or a predefined method.
[0529] 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. The terminal receives the signaling configuration and determines that the cell is an on-demand SIB1 / SSB cell. The signaling can be based on the SCellConfig configuration. The signaling can be based on the MIB indication. The signaling can be based on the reserved bit or check method indication of the PBCH.
[0530] 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 corresponding SIB1 / SSB information based on other cells: the terminal determines that a cell is an on-demand SIB1 / SSB cell according to a predefined method.
[0531] The terminal does not receive SIB1 / SSB within the first time window. The first time window is determined based on signaling indication or predefined method. The terminal receives SIB1 / SSB that does not belong to this cell in other cells, and the terminal determines that the cell corresponding to SIB1 / SSB is an on-demand SIB1 / SSB cell. The terminal receives signaling configuration and determines that the cell is an on-demand SIB1 / SSB cell. Signaling can be based on MIB indication. Signaling can be based on reserved bits or verification method indication of PBCH.
[0532] Base station side:
[0533] A base station supporting network energy saving determines whether to send a downlink signal and / or channel based on the types of different cells, and the signal and / or channel includes at least SSB and / or SIB1.
[0534] Method 1: A base station supporting network energy saving indicates that a 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: the base station sends the WUS configuration corresponding to the on-demand SIB1 / SSB cell.
[0535] The base station sends the following indication signaling to indicate that the cell is an on-demand SIB1 / SSB cell. The signaling can be based on SCellConfig configuration. The signaling can be based on MIB indication. The signaling can be based on PBCH reserved bits or verification mode indication.
[0536] 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.
[0537] The base station sends the following indication signaling to indicate that the cell is a SIB1 / SSB-less cell. The signaling can be based on SCellConfig configuration. The signaling can be based on MIB indication. The signaling can be based on the reserved bit or check method indication of PBCH.
[0538] In this embodiment, it is assumed that the terminal is a terminal that supports network energy-saving technology. The corresponding base station may be a base station that supports network energy-saving technology. The base station can choose to stop sending some downlink signals or channels according to the network load, the number of resident terminals, the type of service, the service period, etc. Of course, this patent does not limit the decision-making process and strategy of whether the base station sends some downlink signals or channels. The embodiment scheme of the present disclosure mainly defines different cells for different behaviors of base stations or terminals. Exemplarily, the cell can be distinguished by anchor cell or non-anchor cell, or by first type of cell or second type of cell, wherein the first type of cell (anchor cell) and the second type of cell (non-anchor cell) correspond to different behaviors of sending system information / downlink signal or receiving uplink signal on the network side. Correspondingly, the terminal determines different ways of obtaining system information / downlink signal or sending or receiving uplink signal based on the behavior of sending system cells of different networks. Downlink transmission includes but is not limited to: SSB, SIB1, TRS, PDCCH, PDSCH, CSI-RS, other newly defined downlink reference signals, such as PSS and / or SSS, DRS, etc. Uplink signals may include but are not limited to at least one of the following: PRACH, SRS, PUCCH, PUSCH, other newly defined uplink reference signals.
[0539] The embodiments of the present disclosure mainly take 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.
[0540] 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 behaviors of sending SSB / SIB1 on different network sides, as well as the corresponding behaviors of obtaining SSB / SIB1. However, the embodiment of the present disclosure does not limit the concepts that need to be introduced. Exemplarily, 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 an existing semi-static configuration, but a cell that meets the above characteristics is not necessarily defined based on the first type of cell.
[0541] The following lists the possible application scenarios of the embodiments of the present disclosure for exemplary description, but the embodiments of the present disclosure are not limited to the following scenarios:
[0542] Scenario 1: On-demand SSB transmission. The network device chooses to send SSB on demand based on the number of connected users and / or service requirements. This scenario mainly corresponds to the terminal being in a connected state and connected to the Scell. When the network side is in an on-demand SSB period and does not send the corresponding SSB, the terminal can trigger the corresponding SSB transmission based on the corresponding WUS.
[0543] In this scenario, the cells can be divided into the first type of cells and the second type of cells according to the characteristics of the cells sending SSB. The descriptions of the first type of cells and the second type of cells can be as follows: First type of cells: cells where the base station normally sends SSB based on semi-static configuration; Second type of cells: cells where the base station sends SSB based on the on-demand mode;
[0544] Example 1.1:
[0545] Distinguish between the first type of cell and the second type of cell based on the configuration signaling of the network: illustratively, the base station may indicate that the Scell is a first type of cell or a second type of cell through a newly defined field in the RRC signaling SCellConfig.
[0546] Exemplarily, the base station may indicate, through secondary cell activation (Scell activation) signaling, that the corresponding Scell is one of the first type cell and / or the second type cell.
[0547] Example 1.2:
[0548] The first type of cell and the second type of cell are distinguished based on the configuration of WUS. Exemplarily, the base station may send the WUS configuration based on the secondary cell configuration (SCellConfig) information element (Inforation Element, IE) or other IE. In one embodiment, the WUS configuration may indicate that the corresponding secondary cell is a first type of cell or a second type of cell. In one embodiment, the first type of cell and the second type of cell are distinguished based on the cell to which the WUS configuration is applied. For example, the WUS configuration may be based on the Pcell configuration or the Scell configuration. After the terminal receives the WUS configuration and the cell corresponding to the WUS configuration, it determines that the cell corresponding to the WUS configuration is a second type of cell. After the terminal receives the above-mentioned WUS configuration, if it is determined that the corresponding secondary cell Scell is a first type of cell, the terminal receives the corresponding SSB based on the SSB corresponding semi-static signaling configuration.
[0549] Embodiment 1.3: Exemplarily, it can be determined based on a predefined method. If the terminal does not receive the corresponding SSB 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 SSB periods. The starting position of the first time window is the period in which the terminal currently receives SSB. N is determined based on a predefined or signaling configuration method, and exemplarily, N=3. If it is determined that the corresponding Scell is a second-category cell, the terminal sends a WUS on demand to request the transmission of the corresponding SSB. If it is determined that the corresponding Scell is a second-category cell, the terminal determines that the corresponding SSB cannot be received within a period of time. The WUS that triggers the SSB transmission can be sent on the primary cell or on the secondary cell. In some embodiments, the WUS can be a specific RRC signaling, a MAC CE signaling, or a physical layer signal. Based on the above scenario, the terminal can obtain the SSB in the following way. Figure 5A or Figure 5B shown.
[0550] like Figure 5A As shown, the downlink transmission method performed by the terminal may include:
[0551] Step 1: Determine that the cell is a first-class cell;
[0552] Step 2: The gNB of the second type of cell stops sending SSB;
[0553] Step 3: The terminal attempts to receive SSB but fails.
[0554] Step 4: The terminal sends WUS;
[0555] Step 5: gNB receives WUS;
[0556] Step 6: gNB sends SSB.
[0557] like Figure 5A As shown, the downlink transmission method performed by the terminal may include:
[0558] Step 1: Determine that the cell is a second type cell;
[0559] Step 2: Send SSB;
[0560] Step 3: The terminal fails to receive SSB.
[0561] Step 4: The terminal continues to try to receive SSB.
[0562] 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 comes 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.
[0563] Scenario 2: On-demand SIB1 in single carrier scenario
[0564] The network side can choose to send SIB1 on demand based on the access user and / or service requirements. This scenario mainly corresponds to the terminal in idle state and / or inactive state. 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.
[0565] If the terminal sends the corresponding WUS, it needs to obtain the corresponding WUS configuration.
[0566] Consider that the scenario mainly corresponds to a single carrier scenario.
[0567] 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. Figure 5C As shown, if there is no terminal in the cell, the transmission of common signals or channels is reduced. If a terminal enters, the base station is awakened and the transmission of common signals or channels is started. Figure 5D As shown, 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.
[0568] In this scenario, according to the characteristics of the cells sending SIB1, the cells can be divided into the first type of cells and the second type of cells. The first type of cells: cells where the base station normally sends SIB1 based on semi-static configuration.
[0569] The second type of cell: a cell in which the base station sends SIB1 based on the on-demand mode.
[0570] The first type of cells and the second type of cells may be distinguished in at least one of the following ways:
[0571] Embodiment 2.1: The first type of cells and the second type of cells may be determined based on a predefined manner.
[0572] 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.
[0573] The first time window may be determined based on signaling or in a predefined manner.
[0574] 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.
[0575] The starting position of the first time window is the period of the terminal's current blind detection type 0 CSS. N is determined based on a predefined or signaling configuration manner, and illustratively, N=3.
[0576] 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 checks the SI-RNTI based on the above Searchspace#0 and CORESET#0 for DCI1_0.
[0577] If the terminal fails to detect the corresponding DCI of the scheduling SIB1 for M consecutive blind detection periods, it determines that the cell is a second type cell.
[0578] If the terminal fails to blindly detect the corresponding scheduling SIB1 for M consecutive blind detection periods, and fails to receive the corresponding SIB1 when blindly detecting the corresponding DCI, the terminal determines that the cell is a second type cell.
[0579] Exemplarily, the terminal determines the state of the cell in the following manner: If the terminal does not receive the corresponding SIB1 within the first time window, the terminal determines the type of the corresponding cell. The first time window starts with the blind detection period of the current SIB1 where the terminal is located, and N consecutive configuration SIB1 periods.
[0580] The corresponding cell may be a cell corresponding to on demand SIB1. Alternatively, the cell is a cell that the terminal is prohibited from accessing.
[0581] The terminal stores the status information of the cell.
[0582] 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.
[0583] M is determined based on a predefined or signaling configuration. Exemplarily, M=1.
[0584] A blind detection period here may be the aforementioned receiving opportunity.
[0585] 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, and successfully receives the corresponding SIB1.
[0586] 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 of the 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.
[0587] 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 of other wireless access technologies to the current network, it needs to obtain system information.
[0588] Exemplarily, the terminal determines the type of the cell based on the following method. If the terminal does not receive the corresponding SIB1 within the first time window, the terminal determines that the cell is a cell that sends the first transmission based on the on-demand mechanism or determines that the cell is a cell that does not send the first transmission. The first transmission here includes but is not limited to SIB1, SSB and / or SIBx, where x can be a positive integer greater than or equal to 2.
[0589] In some embodiments, the first time window starts with the blind detection period of the current SIB1 where the terminal is located, and N consecutive configured SIB1 periods.
[0590] In some embodiments, the second cell is a cell corresponding to the on demand SIB1.
[0591] In some embodiments, the cell that does not send the first transmission is a cell that is prohibited from access by the terminal.
[0592] In some embodiments, the terminal stores cell information, which may indicate the type of the corresponding cell, to facilitate subsequent cell selection, reselection, access or residence.
[0593] In some embodiments, upon receiving the configuration information of the WUS corresponding to the cell, the terminal determines whether the cell is a cell that sends the first transmission based on the on-demand mechanism, otherwise the cell is determined to be a cell that does not send the first transmission. That is, under the condition that the WUS configuration information of the cell is not received, the terminal cannot send the WUS to trigger the sending of the first transmission. If the terminal does not receive the corresponding first transmission within the first time window, the cell can be considered as a cell that does not send the first transmission.
[0594] In some embodiments, the first type of cell and / or the second type of cell may determine the type of the cell based on a predefined rule. Exemplarily, if the terminal does not receive the corresponding SSB within the first time window, the terminal determines that the cell is a second type of cell. Embodiment 2.2: Exemplarily distinguishing between the first type of cell and the second type of cell based on WUS configuration.
[0595] The WUS configuration is used for the terminal to send a WUS on the configured resources, and the WUS can trigger SIB1 transmission.
[0596] 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.
[0597] As another example, the terminal attempts 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.
[0598] 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 DCI1_0 of SI-RNTI verification 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.
[0599] 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.
[0600] 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.
[0601] 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.
[0602] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding MIB, 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.
[0603] 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.
[0604] Embodiment 2.3-2: The indication signaling may be Kssb. Kssb is indicated based on ssb-SubcarrierOffset and the information bits in the PBCH.
[0605] Example 2.3-2-1: The SSB of the corresponding cell may be a cell associated with CORESET#0. For FR1, Kssb is greater than or equal to 0 and less than or equal to 23. For FR2, Kssb is greater than or equal to 0 and less than or equal to 11. 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. The first value set may be determined based on signaling or a predefined method. Exemplarily, the first value set corresponds to an even number for Kssb, and the second value set corresponds to an odd number for Kssb. Also exemplarily, the first value set includes a value range that is different from the value range of the second value set.
[0606] Exemplarily, the indication signaling may 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 of cell. 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 elaborated on this.
[0607] For terminals that support network energy saving, after receiving SSB and reading the corresponding Kssb, it can be determined based on signaling whether the cell to which it belongs is one of the first type of cell or the second type of cell, and the frequency domain position of CRB can be determined based on Kssb. 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.
[0608] Example 2.3-2-2: The SSB of the corresponding cell may be a cell that is not associated with CORESET#0. For FR1, Kssb is greater than or equal to 24. For FR2, Kssb is greater than 11. 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. The first value set may be determined based on signaling or a predefined method. Exemplarily, the second value set corresponds to Kssb=30, and the first value set is Kssb not equal to 30. Exemplarily, for a terminal that supports network energy saving, after receiving the SSB and reading the corresponding Kssb=30, it may be determined that the cell is in the second-category cell based on signaling, and the frequency domain position of the CRB may be determined based on Kssb.
[0609] The specific method is as follows: The terminal determines the lowest subcarrier of SSB and N based on Kssb-offset CRB The lowest subcarrier offset, N CRBThe lowest CRB that has frequency domain intersection with the CRB. Kssb-offset = Kssb-9, or Kssb-offset = Kssb mod 24; this method can be applied to the scenario of Kssb = 30, and can also be applied to other Kssb value scenarios. Exemplarily, for a terminal that supports network energy saving, under the condition that the cell is determined to be a second-class cell based on signaling, the corresponding pdcch-ConfigSIB1 can be read to determine the corresponding SearchSpace#0 or CORESET#0. Exemplarily, in some embodiments, the terminal determines based on the indication signaling Terminal based Determine the frequency domain position of the CRB grid, and further determine the frequency domain position of CORESET#0 based on the frequency domain position of the CRB. The indication signaling may be sent by the first cell or based on the second cell. In some embodiments, the indication signaling may be configuration information of the WUS. Also exemplarily, the indication signaling may be a type of the aforementioned second information. Also exemplarily, the indication signaling may be a type of the aforementioned third information. 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.
[0610] Embodiment 2.4: The distinction can be based on indication signaling. The indication signaling can be carried based on PBCH.
[0611] Embodiment 2.4-1: The indication signaling may be a reserved bit in the PBCH.
[0612] For example, Conditional bits, or Less than or equal to 8 or Bit.
[0613] 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.
[0614] 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:
[0615]
[0616] Table 4
[0617] Example 2.4-2:
[0618] 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 accordingly. 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.
[0619] 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 Class I cell. The terminal not supporting network energy saving demodulates the corresponding PBCH based on the existing CRC check, fails to successfully demodulate the corresponding PBCH, and continues to perform the cell search process.
[0620] 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 checks the SI-RNTI based on the above Searchspace#0 and CORESET#0 for DCI1_0.
[0621] If the terminal fails to detect the corresponding DCI scheduling SIB1 for M consecutive blind detection cycles, and / or detects the corresponding DCI but fails to 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.
[0622] 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, 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 has not blindly detected the corresponding DCI of the 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.
[0623] Scenario 3: On-demand SIB1 transmission scenario of multiple carriers.
[0624] The network side selects to send SIB1 on demand based on the access user and / or service requirements, etc. This scenario mainly corresponds to the terminal in the idle state and / or inactive state.
[0625] like 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.
[0626] If the terminal sends WUS to trigger the network to send SSB and / or SIB1, the terminal needs to obtain the WUS configuration.
[0627] 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 from the anchor cell, or can obtain the corresponding WUS configuration based on the anchor cell or non-anchor cell.
[0628] In this scenario, two types of cells are defined, namely, first type cells and second type cells.
[0629] First type of 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.
[0630] 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.
[0631] In some embodiments, the second type cell may also be a cell that does not send the first transmission.
[0632] The two cells can be distinguished based on the following:
[0633] Embodiment 3.1: It can be determined based on a predefined manner.
[0634] 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. 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 of type 0 CSS that schedules SIB1. The starting position of the first time window is the period of the terminal's current blind detection type 0 CSS. N is determined based on a predefined or signaling configuration method, and exemplarily, N=3.
[0635] Exemplarily, if the terminal searches 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.
[0636] 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, and successfully receives the corresponding SIB1.
[0637] If the terminal successfully resides on the cell and needs to obtain updated system information, for example, if the terminal fails to 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, illustratively, M=1;
[0638] Exemplarily, under the condition that 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.
[0639] Exemplarily, under the condition that 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 first type of cell sends a WUS request about the second type of cell, and the WUS request carries the information of 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.
[0640] 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.
[0641] Embodiment 3.2: The first type of cell and the second type of cell 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.
[0642] Exemplarily, 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. Alternatively, when the terminal receives the SSB but attempts and successfully receives the WUS configuration corresponding to the cell before receiving SIB1, the terminal determines that the cell corresponding to the WUS configuration is a second type cell.
[0643] 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 DCI1_0 of SI-RNTI verification 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.
[0644] 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.
[0645] Embodiment 3.3: The first type of cells and the second type of cells may be distinguished based on indication signaling.
[0646] The indication signaling may be carried based on the MIB or the MIB and the PBCH.
[0647] Embodiment 3.3-1: The indication signaling may be an idle bit in the MIB.
[0648] 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.
[0649] The indication signaling may be the last bit of ssb-SubcarrierOffset in the MIB. For example, if the spare bit indication is 0, it indicates that the corresponding cell is a first-class cell. If the spare bit indication is 1, it indicates that the corresponding cell is a first-class cell.
[0650] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding MIB, 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.
[0651] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding MIB, the idle bit legacy terminal ignores the information field indication.
[0652] Embodiment 3.3-2: The indication signaling may be Kssb. Kssb is indicated based on the ssb-SubcarrierOffset and the information bits in the PBCH.
[0653] Embodiment 3.3-2-1: Exemplarily, the SSB of the corresponding cell may be a cell associated with CORESET#0, that is, for FR1, Kssb is greater than or equal to 0 and less than or equal to 23. For FR2, Kssb is greater than or equal to 0 and less than or equal to 11. When Kssb 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.
[0654] 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.
[0655] 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 disclosure embodiment will not be elaborated on this.
[0656] For terminals that support network energy saving, after receiving SSB and reading the corresponding Kssb, it can be determined based on signaling whether the cell to which it belongs is a first type cell or a second type cell, and the frequency domain position of the CRB can be determined based on Kssb.
[0657] 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.
[0658] Example 3.3-2-2:
[0659] The SSB of the corresponding cell may be a cell not associated with CORESET#0, that is, for FR1 used by a cell not associated with CORESET#0, Kssb is greater than or equal to 24, or, for FR2 used by a cell not associated with CORESET#0, Kssb is greater than 11. When Kssb 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.
[0660] The first value set may be determined based on signaling or a predefined method. For example, the second value set corresponds to Kssb=30, and the first value set is that Kssb is not equal to 30.
[0661] In some embodiments, the terminal determines Kssb according to network signaling, and determines the subcarrier spacing according to Kssb. In some embodiments, Kssb is less than a specified value, and the subcarrier spacing can be considered equal to Kssb. In some embodiments, Kssb is greater than or equal to a specified value, and the subcarrier spacing can be determined according to Kssb. Exemplarily, the specified 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.
[0662] For example, for a terminal supporting network energy saving, after receiving SSB and reading the corresponding Kssb=30, it can determine that the cell is a second type cell based on signaling, and determine the frequency domain position of CRB based on Kssb. The specific method is as follows:
[0663] The terminal determines the lowest subcarrier of SSB and N based on Kssb-offset CRB The lowest subcarrier offset, N CRB The lowest CRB that has frequency domain intersection with the CRB. Kssb-offset = Kssb-9, or Kssb-offset = Kssb mod 24. In some embodiments, this determination of Kssb-offset or determination of the lowest subcarrier of the SSB and N CRBThe method of offsetting the lowest subcarrier can be applied to the scenario where Kssb=30, and can also be applied to other Kssb value scenarios.
[0664] In some embodiments, the terminal determines based on the indication signaling Terminal based Determine the frequency domain position of the CRB grid. The indication signaling may be sent by the first cell or based on the second cell. In some embodiments, the indication signaling may be configuration information of the WUS. In another exemplary embodiment, the indication signaling may be one of the aforementioned second information.
[0665] In some embodiments, It can be the aforementioned first parameter.
[0666] Exemplarily, for a terminal supporting network energy saving, under the condition that the cell is determined as a second-category cell based on signaling, the corresponding pdcch-ConfigSIB1 can be read to determine the corresponding SearchSpace#0 or CORESET#0;
[0667] 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.
[0668] Embodiment 3.4: The distinction can be based on indication signaling.
[0669] The indication signaling can be carried based on PBCH, that is, the type of cell can be distinguished through PBCH information.
[0670] Embodiment 3.4-1: The indication signaling may be a reserved bit in the PBCH. For example, Conditional bits, or Less than or equal to 8 or Bit.
[0671] 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.
[0672] 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.
[0673] Embodiment 3.4-2: The indication signaling may be different CRCs in the PBCH. Exemplarily, a new CRC is introduced, and the base station supporting network energy saving checks the PBCH based on the newly introduced CRC and sends accordingly.
[0674] 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.
[0675] 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 type cell.
[0676] The terminal that does not support network energy saving demodulates the corresponding PBCH based on the existing CRC check, fails to successfully demodulate the corresponding PBCH, and continues to perform a cell search process.
[0677] Exemplarily, 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 the WUS request corresponding to the SIB1 transmission;
[0678] Exemplarily, 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 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-class cell, to obtain the WUS configuration of the second-class cell. After obtaining the WUS configuration, the first-class cell sends a WUS request about the second-class cell, and the WUS request carries the information of the second-class cell. After the first-class cell base station transmits the request to the second-class cell base station through information exchange, the second-class cell base station receives the WUS request.
[0679] Exemplarily, 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 obtained the WUS configuration of the cell corresponding to the SSB, the terminal will send a WUS request in the second-category cell to request the corresponding SIB1 transmission.
[0680] Exemplarily, if the terminal determines that the cell is a second type cell and successfully obtains the corresponding SIB1, the terminal can receive the corresponding WUS configuration based on the cell. And if it needs to obtain and update SIB1 later, the terminal can send a WUS request based on the configuration to obtain the corresponding SIB1.
[0681] Scenario 4: SIB1 / SSB-less cell.
[0682] The network side chooses not to send SIB1 / SSB based on access users and / or service requirements.
[0683] The scenario mainly corresponds to the terminal in idle state and / or inactive state. Fig. 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 CC2 based on CC1.
[0684] Example 3.5:
[0685] In one case, the type of a cell may be determined based on information (ie, signaling) sent by a cell, for example, based on one or more signaling sent by a cell. In another case, the type of a cell may be indicated in combination with signaling sent by two or more cells.
[0686] Exemplarily, the indication signaling of cell 1 may be carried by the MIB or MIB and PBCH or system information, RRC signaling, MAC CE and DCI of the second cell, and the indication signaling of cell 1 may include but is not limited to the configuration information and / or system information (System Information, SI) of WUS. Exemplarily, the SI may include but is not limited to SIB1 and / or SIBx. For example, the indication signaling may also be RRC signaling or other indication signaling, which is not limited in the embodiments of the present disclosure. For specific signaling indications / implementations, please refer to the above-mentioned Examples 3.1 to 3.4, which will not be repeated here. The second cell here may be a first type cell. For example, the second cell may be a cell such as the anchor cell of the terminal.
[0687] The embodiment takes the first information as the configuration information of the WUS of cell 1 and the second information as the subcarrier offset parameter Kssb of cell 1 as an example to illustrate the specific scheme of the embodiment of the present disclosure:
[0688] Example 1: The terminal receives an indication signaling sent by cell 1 or cell 2 indicating that cell 1 may be a second-category cell. Exemplarily, under the condition that cell 1 is a second-category cell and Kssb of cell 1 satisfies the following conditions: Kssb is greater than 23 when the cell uses FR1, and Kssb is greater than 11 when cell 1 uses FR2, the terminal determines that cell 1 is a second-category cell.
[0689] Exemplarily, for a terminal supporting network energy saving, when receiving an SSB for cell 1 and determining that the Kssb corresponding to cell 1 is greater than 23 (FR1) or greater than 11 (FR1) according to the SSB, in order to further determine the frequency domain position of the CRB grid, thereby determining the frequency domain position of CORESET#0 and / or SIB1. The terminal can determine based on the indication signaling Based on Determine the frequency domain position of the CRB grid. The indication signaling may be the indication signaling sent by cell 2 or the indication signaling sent by cell 1. The indication signaling may include but is not limited to MIB or MIB and PBCH or RRC or MAC CE or DCI. In some embodiments, the indication signaling may also be configuration information of WUS. Exemplarily, if cell 1 uses FR1, Kssb is less than or equal to 23, and if cell 1 uses FR2, Kssb is less than or equal to 11.
[0690] The terminal receives the indication signaling sent by cell 1 or cell 2 indicating that cell 1 may be a second-category cell. Exemplarily, under the condition that the corresponding indication signaling indicates that cell 1 is a second-category cell, if the Kssb of cell 1 does not meet the following conditions: Kssb is greater than 23 when the cell uses FR1, and Kssb is greater than 11 when cell 1 uses FR2, then the terminal determines that cell 1 is not associated with CORESET#0, or the terminal determines that the scenario is an error scenario (error case), or the terminal determines that cell 1 is a second-category cell or a first-category cell. Exemplarily, the first-category cell is a cell that sends a first transmission based on a semi-static configuration and / or a periodic configuration; the second-category cell is a cell that sends a first transmission based on an on-demand mode, or the second-category cell is a cell that does not send a first transmission, or the second-category cell is a cell that sends the first transmission by other cells. In one embodiment, the first transmission may be SIB1.
[0691] Correspondingly, the terminal receives the indication signaling of cell 2 to determine the type of the corresponding cell. Exemplarily, under the condition that the indication signaling indicates that cell 1 is not a second-category cell, if the Kssb of the corresponding cell 1 satisfies the following conditions: when the cell uses FR1, Kssb is greater than 23, and when cell 1 uses FR2, Kssb is greater than 11, then the terminal determines that cell 1 is not associated with CORESET#0, and exemplary, cell 1 is a cell that does not transmit SIB1.
[0692] Correspondingly, the terminal receives the indication signaling of the cell and / or cell 2, indicating the corresponding cell. Exemplarily, under the condition that cell 1 is a second-category cell, if the Kssb of cell 1 does not meet the following conditions: when the cell uses FR1, Kssb is greater than 23, and when cell 1 uses FR2, Kssb is greater than 11, the terminal determines that the scenario is an error scenario or an abnormal scenario (error case), or the terminal determines that cell 1 is a second-category cell, or the terminal determines that cell 1 is a first-category cell.
[0693] Correspondingly, the terminal receives the indication signaling of cell 1 and / or cell 2 to indicate the type of the corresponding cell. Exemplarily, under the condition that cell 1 is not a second-category cell, if Kssb of cell 1 satisfies the following conditions: Kssb is greater than 23 when the cell uses FR1, and Kssb is greater than 11 when cell 1 uses FR2, the terminal determines that cell 1 is a cell not associated with CORESET#0, and exemplarily, cell 1 is a cell that does not transmit SIB1.
[0694] Example 2: The terminal receives the indication signaling of cell 2 indicating the corresponding cell. Exemplarily, under the condition that the indication signaling indicates that cell 1 is a second-category cell, if the Kssb of the corresponding cell 1 satisfies the following conditions: kssb is equal to a specific value, exemplarily, if cell 1 uses FR1, Kssb=30, or, if cell 1 uses FR2, Kssb=14, then the terminal determines that cell 1 is a second-category cell.
[0695] For example, for a terminal supporting network energy saving, after determining Kssb, it is necessary to further determine the frequency domain position of the CRB grid. The terminal can determine based on the indication signaling Based on Determine the frequency domain position of the CRB grid. The indication signaling may be sent by the first type of cell and / or the second type of cell. For example, the indication signaling may be sent by the first cell, the second cell and / or the third cell. Exemplarily, the indication signaling may be configuration information of the WUS. Exemplarily, when cell 1 uses FR1, Kssb is less than or equal to 23. Exemplarily, when cell 1 uses FR2, Kssb is less than or equal to 11.
[0696] Correspondingly, the terminal receives the indication signaling of the cell and / or cell 2, indicating the corresponding cell. Exemplarily, under the condition that cell 1 is a second-category cell, if the Kssb of cell 1 does not meet the following conditions: when cell 1 uses FR1, Kssb=30, or, when cell 1 uses FR2, Kssb=14, the terminal determines that the scenario is an error scenario or an abnormal scenario (error case), or the terminal determines that cell 1 is a second-category cell, or the terminal determines that cell 1 is a first-category cell.
[0697] Correspondingly, the terminal receives the indication signaling of cell 1 and / or cell 2 to indicate the type of the corresponding cell. Exemplarily, under the condition that cell 1 is not a second-category cell, if Kssb of cell 1 satisfies the following conditions: when cell 1 uses FR1, Kssb=30, or, when cell 1 uses FR2, Kssb=14, the terminal determines that cell 1 is a cell not associated with CORESET#0. Exemplarily, cell 1 is a cell that does not transmit SIB1.
[0698] In some embodiments, the first cell is a cell of a type to be determined.
[0699] In some embodiments, the system information corresponding to the first cell is transmitted based on an on-demand mode.
[0700] In some embodiments, the system information corresponding to the first cell needs to be transmitted based on WUS triggering.
[0701] In some embodiments, the third cell is a primary cell of the terminal and the first cell is a secondary cell of the terminal; or, the third cell is a secondary cell of the terminal and the first cell is a primary cell of the terminal.
[0702] In some embodiments, the second cell may be a regular cell, for example, the second cell may be a cell that periodically sends the first transmission. Exemplarily, the second cell is adjacent to or partially overlaps the coverage of the first cell. In some embodiments, the third cell may be a type of the second cell, but the second cell is not limited to the third cell.
[0703] The embodiments of the present disclosure take SIB1 as an example to illustrate the embodiments of the present disclosure. Other signals, such as SSB, are also within the protection scope of the embodiments of the present disclosure and are not limited thereto.
[0704] Based on this scenario, the correspondence can be defined as follows:
[0705] Type 1 cell: a cell where the base station normally sends SIB1 based on semi-static configuration. For example, the cell can send SIB1 information of at least one cell including the cell itself. For example, the cell can be Fig. 5F Corresponding CC1;
[0706] The second type of cell: a cell where the base station does not send SIB1. For example, the cell may be Fig. 5F Corresponding CC2;
[0707] The two cells can be distinguished based on the following:
[0708] Embodiment 4.1: The type of the cell may be determined based on a predefined manner.
[0709] 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 in a predefined manner.
[0710] 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.
[0711] 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, and illustratively, N=3.
[0712] 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 checks the DCI1_0 of the SI-RNTI check based on the above Searchspace#0 and CORESET#0.
[0713] If the terminal fails to detect the corresponding DCI scheduling SIB1 for M consecutive blind detection cycles, and / or detects the corresponding DCI but fails to 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.
[0714] Exemplarily, under the condition that the terminal does not 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, and receives the corresponding SSB, and can initiate the RACH process based on the SSB and the obtained SIB1 of the second type of cell.
[0715] Exemplarily, under the condition that the terminal has acquired SIB1 of the cell corresponding to the SSB, the terminal can initiate a RACH process in the second type of 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 the 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 where the terminal is located, and N consecutive configuration SIB1 periods.
[0717] The first sub-category cell is a cell corresponding to on demand SIB1, and the second sub-category cell is a cell prohibited to the terminal.
[0718] The terminal stores the status information of the cell.
[0719] 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.
[0720] Embodiment 4.2: The types of cells may be distinguished based on SIB1.
[0721] 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 SIB1 is the second type of cell.
[0722] Embodiment 4.3: Exemplarily, the distinction can be based on indication signaling, and the indication signaling can be carried based on MIB or MIB and PBCH. Embodiment 4.3-1: The indication signaling can be an idle bit in MIB. Exemplarily, 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.
[0723] 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.
[0724] For a terminal that supports network energy saving, after receiving the SSB and reading the corresponding MIB, 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.
[0725] For legacy terminals that do not support network energy saving, after receiving the SSB and reading the corresponding MIB, the idle bit reservation will be determined, and the legacy terminal will ignore the information field indication. Or the ssb-SubcarrierOffset is determined to determine the CRB offset of the SSB.
[0726] Embodiment 4.3-2: The indication signaling may be Kssb. Kssb is indicated based on ssb-SubcarrierOffset and the information bits in the PBCH.
[0727] Example 4.3-2-1: Exemplarily, the SSB of the corresponding cell may be a cell associated with CORESET#0.
[0728] For FR1, Kssb is greater than or equal to 0 and less than or equal to 23.
[0729] For FR2, Kssb is greater than or equal to 0 and less than or equal to 11.
[0730] When Kssb belongs to the first value set, the cell associated with SSB is a first type cell.
[0731] When Kssb belongs to the second value set, the cell associated with SSB is a second type of cell.
[0732] 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.
[0733] 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 disclosure embodiment will not be elaborated on this.
[0734] For terminals that support network energy saving, after receiving SSB and reading the corresponding Kssb, it can be determined based on signaling whether the cell to which it belongs is a first type cell or a second type cell, and the frequency domain position of the CRB can be determined based on Kssb.
[0735] Exemplarily, under the condition that the terminal determines that the cell is a second-category cell, if the terminal has acquired the SIB1 information corresponding to the second-category cell, the terminal receives the cell SSB and may try to access the cell.
[0736] For example, when the terminal determines that the cell is a second-category cell, if the terminal 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 the first-category cell is found and the corresponding SIB1 information is obtained.
[0737] 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.
[0738] Embodiment 4.3-2-2: The SSB of the second type of cell may be a cell that is not associated with CORESET#0.
[0739] For FR1, Kssb is greater than or equal to 24.
[0740] For FR2, Kssb is less than or equal to 11.
[0741] Exemplarily, the SSB of the first type of cell may be a cell associated with CORESET#0.
[0742] For FR1, the corresponding Kssb is less than 24.
[0743] For FR2, Kssb is less than or equal to 11.
[0744] When Kssb belongs to the first value set, the cell associated with SSB is a first type cell, and when Kssb belongs to the second value set, the cell associated with SSB is a second type cell.
[0745] The first value set may be determined based on signaling or a predefined manner. Exemplarily, the second value set corresponds to Kssb=30.
[0746] The first value set is that Kssb is not equal to 30.
[0747] For example, for a terminal supporting network energy saving, after receiving SSB and reading the corresponding Kssb, the cell can be determined as a second type cell based on signaling, and the frequency domain position of the CRB can be determined based on Kssb. The specific method is as follows:
[0748] The terminal determines the lowest subcarrier of SSB 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.
[0749] N_ CRB The common resource block (CRB) with the smallest frequency domain index among the CRBs where the SSBs have overlap in the frequency domain.
[0750] Kssb-offset is the offset of Kssb.
[0751] For FR1, Kssb-offset=Kssb-8, or Kssb-offset=Kssb mod 24.
[0752] For FR2, Kssb-offset=Kssb-4, or Kssb-offset=Kssbmod12.
[0753] Exemplarily, during a cell search, 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.
[0754] Exemplarily, when the terminal determines that the cell is a second-category cell, if the terminal 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 a first-category cell is found and the corresponding SIB1 information is obtained.
[0755] 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.
[0756] Embodiment 4.4: Exemplarily, the distinction may be based on indication signaling, and the indication signaling may be carried based on PBCH.
[0757] Embodiment 4.4-1: The indication signaling may be a reserved bit in the PBCH. For example, Conditional bits, or Less than or equal to 8 or Bit.
[0758] 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.
[0759] 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.
[0760] Embodiment 4.4-2: The indication signaling may be different CRCs in the PBCH. Exemplarily, a new CRC is introduced, and the base station supporting network energy saving checks the PBCH based on the newly introduced CRC and sends accordingly.
[0761] 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.
[0762] 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 Class I cell. The terminal not supporting network energy saving demodulates the corresponding PBCH based on the existing CRC check, fails to successfully demodulate the corresponding PBCH, and continues to perform the cell search process.
[0763] Exemplarily, 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;
[0764] Exemplarily, 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 obtained the WUS configuration of the cell corresponding to the SSB, the terminal will send a WUS request in the second-category cell to request the corresponding SIB1 transmission.
[0765] Exemplarily, if the terminal determines that the cell is a second-category cell and successfully acquires the corresponding SIB1, the terminal may continue to receive other system information based on the cell, or initiate a RACH process.
[0766] The embodiments of the present disclosure are mainly based on different scenarios to meet the requirements for determining different cell types, which is conducive to achieving consistent understanding between the base station and the terminal and reducing the complexity of terminal operations.
