[0059] Step 200: The terminal determines the first information based on the first object.

[0060] To enable terminals to search for suitable cells and synchronize with the selected cells, network broadcast synchronization signals and provide certain primary information about the cells are typically required. Synchronization signals mainly include primary synchronization signals and secondary synchronization signals. The Physical Broadcast Channel (PBCH) carries the most important system information and is also called the Master Information Block (MIB).

[0080] In one embodiment, the terminal determines the type of the first MIB, the size of the first MIB, and / or whether the first MIB exists or whether to send the first MIB, based on the first object.

[0081] In one embodiment, the terminal determines the type of the first SSB, the size of the PBCH payload corresponding to the first SSB, and / or whether the first SSB exists or whether to send the first SSB, based on the first object.

[0082] In one embodiment, the terminal determines at least one of the following based on the first object: the type of the first MIB or the type of the first SSB, the size of the PBCH payload corresponding to the first SSB or the size of the MIB, and whether to send the first MIB or the first SSB.

[0101] The first object will be explained in detail below.

[0102] 1) The first bit or field in the PBCH payload of the first SSB;

[0103] When multiple SSB / MIB types or sizes are introduced, the presence or transmission of different SSB types or sizes can be determined by specific bits or fields in the PBCH payload, ensuring that the MIB can be parsed after decoding.

[0104] Optionally, the first information of the first SSB or the first MIB can be determined based on the first bit or field in the PBCH payload of the first SSB, such as a specific field in the L1 payload (information bits generated by the physical layer) carried by the PBCH.

[0105] The first bit or field is a specific position in the PBCH payload, and the embodiments of this application do not impose specific limitations.

[0106] 2) The second bit or field in the first MIB;

[0107] Optionally, the first information can be determined based on the second bit or field in the first MIB.

[0108] For example, the first information can be determined by the contents of the first N bits of the MIB of the PBCH, where N is a positive integer, such as 1.

[0109] Optionally, the first information may be indirectly indicated through other fields of the MIB in the PBCH.

[0110] For example, when a field in the first MIB indicates that the cell is an NTN cell, it indirectly indicates that there is no second MIB.

[0111] For example, when a certain field of the first MIB indicates that the cell is an energy-saving cell, it indirectly indicates that there is a second MIB.

[0112] 3) The first signal of the first SSB;

[0113] Optionally, the first information can also be specified by the first signal of the first SSB. Optionally, the first signal of the first SSB may include the primary synchronization signal (PSS), the secondary synchronization signal (SSS), the demodulation reference signal (DMRS), etc.

[0122] Optionally, the first signal is determined based on at least one of the DMRS port of the PBCH and the type of the DMRS sequence of the PBCH.

[0123] The information transmission method provided in this application embodiment can determine the type, size, and / or whether to send or exist of the first MIB or the first SSB based on specific bits or fields in the PBCH payload or MIB of the first SSB. This achieves support for multiple MIB types or SSB types or MIB sizes or the PBCH payload size of the SSB or the existence of a specific type of MIB or a specific type of SSB, which can improve the flexibility of terminal access to the network in different application scenarios.

[0124] 4) The second information corresponding to the first SSB or the first MIB;

[0127] a) Blind search indication information corresponding to the first SSB or the first MIB, wherein the blind search indication information is used to indicate whether to perform blind search based on the synchronization grid or not;

[0128] The first information of the first SSB or the first MIB is determined based on whether the first SSB or the first MIB is a blind search based on a synchronization grid.

[0129] For example, the SSB of a blind search is the Nth SSB, which is a specific type of SSB; the SSB at the position specified by the Nth SSB is the N+1th SSB, and the Nth SSB and the N+1th SSB can have different MIB sizes.

[0130] b) The synchronization raster corresponding to the first SSB or the first MIB;

[0131] Based on the synchronization grid where the first SSB or the first MIB is located or corresponds, determine the first information, such as the type or size of the first SSB or the first MIB, or whether it is sent / exists.

[0132] For example, for SSBs that support different synchronization grid step sizes, SSBs with large synchronization grid step sizes use MIB1, while SSBs with small synchronization grid step sizes use MIB2. This allows the complexity of SSB detection to be balanced by supporting different MIB types.

[0133] c) The frequency range corresponding to the first SSB or the first MIB;

[0134] Based on the frequency range where the first SSB or the first MIB is located or corresponds, determine the first information, including determining at least one of the following: the type of the first SSB, the size of the first SSB, whether the first SSB exists or whether it is being transmitted, the type of the first MIB, the size of the first MIB, and whether the first MIB exists or whether it is being transmitted.

[0135] For example, for SSBs that support different frequency ranges, SSBs with a larger frequency range use MIB1, while SSBs with a smaller frequency range use MIB2.

[0136] d) The frequency band or combination of frequency bands corresponding to the first SSB or the first MIB;

[0138] For example, for SSBs supporting different frequency bands (bandwidths), small-bandwidth SSBs use MIB1, while large-bandwidth SSBs use MIB2. This improves the reliability of the channels where various MIBs reside by supporting different MIB sizes.

[0139] e) The subband corresponding to the first SSB or the first MIB;

[0140] Based on the subband where the first MIB or the first SSB is located or its corresponding subband, determine the first information, including determining at least one of the following: the type of the first SSB, the size of the first SSB, whether the first SSB exists or whether the first SSB is being sent, the type of the first MIB, the size of the first MIB, and whether the first MIB exists or whether the first MIB is being sent.

[0143] For example, for SSBs that support different subcarrier spacings, SSBs with smaller subcarrier spacings use MIB1, while SSBs with larger subcarrier spacings use MIB2.

[0161] Optionally, the first information is determined based on whether the first SSB or the first MIB is sent based on a request or is triggered, including determining at least one of the following: the type of the first SSB, the size of the first SSB, whether the first SSB exists or whether the first SSB is sent, the type of the first MIB, the size of the first MIB, and whether the first MIB exists or whether the first MIB is sent.

[0162] For example, use MIB1 for on-demand SSBs and MIB2 for non-on-demand SSBs.

[0163] o) Third information corresponding to the third SSB associated with the first SSB or the first MIB, the third information including: blind search indication information corresponding to the third SSB; synchronization grid corresponding to the third SSB; frequency range corresponding to the third SSB; bandwidth or bandwidth combination corresponding to the third SSB; subband corresponding to the third SSB; subcarrier spacing corresponding to the third SSB; partial bandwidth BWP corresponding to the third SSB; SSB index or SSB index group corresponding to the third SSB; TRP or TRP group corresponding to the third SSB; cell type corresponding to the third SSB; time window or period in which the third SSB is located; repeated transmission position of the third SSB; transmission period of the third SSB; transmission type of the third SSB.

[0164] It is understood that the third SSB is associated with the first SSB or the first MIB. Based on the third information of the third SSB, the first information can be determined, including determining at least one of the following: the type of the first SSB, the size of the first SSB, whether the first SSB exists or whether it is being transmitted; the type of the first MIB, the size of the first MIB, and whether the first MIB exists or whether it is being transmitted. The third information here refers to at least one of the following: blind search indication information; synchronization grid; frequency range; bandwidth or bandwidth combination; subband; subcarrier spacing; partial bandwidth BWP; SSB index or SSB index group; TRP or TRP group; cell type; time window or period; repeated transmission location; transmission period; transmission type.

[0165] Optionally, the third SSB includes at least one of the following:

[0166] a) The first-level SSB or the preceding-level SSB of the first SSB;

[0167] Based on the third information of the first level or the preceding level SSB of the first SSB, determine the first information, including determining at least one of the following: the type of the first SSB, the size of the first SSB, whether the first SSB exists or whether the first SSB is being sent, the type of the first MIB, the size of the first MIB, and whether the first MIB exists or whether the first MIB is being sent.

[0168] b) SSBs associated with the first SSB quasi-co-location (QCL);

[0169] Based on the third information of the SSB associated with the QCL of the first SSB, the first information is determined, including determining at least one of the following: the type of the first SSB, the size of the first SSB, whether the first SSB exists or whether the first SSB is being sent, the type of the first MIB, the size of the first MIB, and whether the first MIB exists or whether the first MIB is being sent.

[0170] Optionally, the QCL association includes at least one of the following:

[0171] Doppler extension correlation;

[0172] Doppler frequency shift correlation;

[0173] Average gain correlation;

[0174] Average latency correlation;

[0175] Delayed expansion association;

[0176] Receiver spatial parameter association.

[0177] It is understandable that the third SSB is an SSB that is related to the first SSB in terms of Doppler spread, Doppler shift, average gain, average delay, delay spread, or spatial Rx parameters.

[0178] c) Configure the SSB of the first SSB;

[0179] Optionally, based on the third information of the SSB that configures the first SSB (i.e., the SSB where the first MIB is located), the first information is determined, including determining at least one of the following: the type of the first SSB, the size of the first SSB, whether the first SSB exists or whether the first SSB is being sent, the type of the first MIB, the size of the first MIB, and whether the first MIB exists or whether the first MIB is being sent.

[0180] The information transmission method provided in this application embodiment can implicitly determine the first information based on the second information of the first SSB or the first MIB. While supporting multiple MIB types, SSB types, MIB sizes, SSB PBCH payload sizes, the existence of a specific type of MIB, or the existence of a specific type of SSB, it can reduce signaling overhead and improve the flexibility of terminal access to the network in different application scenarios.

[0181] 5) The transmission mode supported by the second object corresponding to the first SSB or the first MIB, wherein the second object includes at least one of the following: carrier, cell, frequency band, subband, transmit / receive point (TRP), SSB index, SSB index group; the transmission mode includes energy-saving transmission or non-energy-saving transmission.

[0182] It should be noted that the transmission modes supported by the frequency band corresponding to the first SSB or the first MIB include: the transmission on the frequency band resources corresponding to the first SSB or the first MIB supports energy-saving transmission or does not support energy-saving transmission.

[0183] Optionally, energy-efficient transmission refers to transmission based on a request or trigger.

[0184] Optionally, the first information is determined based on whether the carrier, cell, frequency band, subband, transmit / receive point (TRP), or corresponding SSB index or SSB group in which the first SSB is located is a carrier, cell, frequency band, subband, TRP, or corresponding SSB index or SSB group that is energy-saving for the network and / or terminal.

[0185] For example, in energy-saving scenarios, MIB1 is used for energy-saving carriers, cells, bands, subbands, TRPs, corresponding SSB indexes, or SSB groups in the network and / or terminals. MIB2 is used for non-energy-saving carriers, cells, bands, subbands, TRPs, corresponding SSB indexes, or SSB groups.

[0186] Optionally, for combinations of the two scenarios above, MIB3 or MIB1 can be used as the first-level SSB and MIB2 as the second-level SSB. This improves the flexibility of MIB content and size under different network terminal energy efficiency requirements.

[0187] 6) The application scenario corresponding to the first SSB transmission;

[0188] Optionally, the application scenarios here include one or more of the following: Low Power Wide Area (LPWA), non-LPWA (such as Enhanced Mobile Broadband (eMBB), scenarios supporting different coverage levels, scenarios with different synchronization accuracy requirements, etc.

[0189] For example, in scenarios supporting different synchronization accuracy requirements, the SSB with low accuracy requirements or simple initial search uses MIB1, while the SSB with high accuracy requirements or second-level search uses MIB2. This reduces the complexity of the initial search, and by using the second-level SSB for more precise measurement and synchronization, the reliability of subsequent channels (such as random access channels) can be improved.

[0190] For example, in scenarios supporting LPWA and non-LPWA, or supporting different coverage levels, MIB1 is used for LPWA or low-bandwidth and / or high-coverage (or with SSB retransmission or exceeding a certain number of SSB retransmissions) carriers, cells, bands, subbands, TRPs, corresponding SSB indexes, or SSB groups. MIB2 is used for eMBB or high-bandwidth and / or normal coverage (or without SSB retransmission or exceeding a certain number of SSB retransmissions) carriers, cells, bands, subbands, TRPs, corresponding SSB indexes, or SSB groups. Optionally, for combinations of the above two scenarios, MIB3 can be used, or MIB1 can be used as the first-level SSB and MIB2 as the second-level SSB. This improves the flexibility of MIB content and size under different service scenarios.

[0191] Optionally, the second SSB includes at least one of the following:

[0192] The SSB corresponding to the other SSB indexes of the first cell, where the first cell is the cell corresponding to the first SSB;

[0193] SSBs that are different from the first SSB type;

[0194] SSB or first system message from the second cell.

[0195] Understandably, the type and / or size and / or existence / transmission of the first SSB or first MIB can be determined based on the second SSB or second MIB. The second SSB can be another SSB in the cell corresponding to the first SSB, an SSB of a different type from the first SSB, or an SSB or first system message (such as SIB1) of the second cell, which is a different cell from the first cell. In other words, the type and / or size and / or existence / transmission of the first SSB or first MIB can be determined based on other SSBs in the same cell; the type and / or size and / or existence / transmission of the first SSB or first MIB can also be determined based on other types of SSBs; or the type and / or size and / or existence / transmission of the first SSB or first MIB can be determined based on SSBs or system messages from other cells.

[0196] The following 7) to 12) are all related expansions of the second SSB and the second MIB, that is, the type and / or size and / or existence / transmission of the first SSB or the first MIB can be determined according to 7) to 12). The first information of the first SSB or the first MIB can be determined directly from specific bits or fields in the PBCH payload of the second SSB or in the MIB. Alternatively, it can be determined directly from the first signal in the second SSB, or implicitly from the second information of the second SSB. It can also be determined based on whether the carrier, cell, frequency band, subband, transmit / receive point (TRP), or corresponding SSB index or SSB group where the second SSB is located is a carrier, cell, frequency band, subband, TRP, or corresponding SSB index or SSB group that is energy-saving for the network and / or terminal. Furthermore, it can be determined based on the application scenario corresponding to the transmission of the second SSB. This system supports multiple MIB types, SSB types, MIB sizes, SSB PBCH payload sizes, the existence of specific types of MIBs, or the existence of specific types of SSBs, thus improving the flexibility of terminal network access in different application scenarios.

[0240] Optionally, the first information is determined based on whether the carrier, cell, frequency band, subband, transmit / receive point (TRP), or corresponding SSB index or SSB group in which the second SSB is located is a carrier, cell, frequency band, subband, TRP, or corresponding SSB index or SSB group that is energy-saving for the network and / or terminal.

[0241] 12) Application scenarios corresponding to the second SSB transmission;

[0242] 13) The third signal;

[0243] Optionally, the first information can also be determined using a third signal. This third signal is independent of the SSB.

[0244] Optionally, the third signal includes at least one of the following:

[0245] Wake-up Signal (WUS);

[0246] First downlink synchronization signal;

[0247] The first signaling is sent on a third object containing SSBs other than the target SSB, wherein the target SSB includes the first SSB and / or the second SSB;

[0248] The second signaling is sent on a third object containing other MIBs besides the target MIB, wherein the target MIB includes the first MIB and / or the second MIB;

[0249] The third object includes at least one of the following: carrier, cell, frequency band, subband, TRP;

[0250] The first signaling or the second signaling includes at least one of the following: RRC signaling, MAC CE, physical layer signaling.

[0251] Optionally, the terminal sends a WUS to the network-side device, which carries the type or size of the SSB or MIB that the terminal expects. Based on the WUS, the network-side device can determine the type or size of the SSB or MIB that the terminal expects, so that the network-side device can respond according to the type or size of the SSB or MIB that the terminal expects.

[0252] Optionally, the first downlink synchronization signal is a downlink synchronization signal other than the SSB. The terminal determines the first information, such as the type and / or size and / or existence / transmission of the first SSB or the first MIB, based on the first downlink synchronization signal.

[0253] Optionally, the first downlink synchronization signal may include: CSI-RS, DMRS, PTRS, TRS, etc.

[0254] Optionally, the terminal determines first information, such as the type and / or size and / or existence / transmission of the first SSB or the first MIB, based on the first signaling transmitted by the carrier, cell, frequency band, subband, or TRP of other SSBs besides the target SSB.

[0255] Optionally, the terminal determines the first information, such as the type and / or size and / or existence / transmission of the first SSB or the first MIB, based on the second signaling sent by the carrier, cell, frequency band, subband, or TRP corresponding to other MIBs besides the target MIB.

[0256] The information transmission method provided in this application embodiment can determine the type and / or size and / or existence / transmission of the first SSB or the first MIB based on a third signal. The third signal can be a WUS signal, other downlink synchronization signals besides the SSB, or signaling sent on a third object where other SSBs or MIBs are located. This method supports different SSB / MIB types or sizes, balances the complexity of SSB detection with the size of information carried by the SSB and the reliability of the SSB, reduces signaling overhead, and improves the flexibility of terminal access to the network in different application scenarios.

[0257] 14) Terminal status;

[0258] For scenarios where different SSBs are supported for different terminal states, MIB1 is used for SSBs of a specific target terminal state (such as RRC idle / inactive and / or connected states), while MIB2 is used for SSBs of another specific target terminal state (such as RRC connected state). This approach improves the balance between the complexity of SSB detection, the size of the information carried by the SSB, and the reliability of the SSB by supporting different MIB types.

[0259] 15) Terminal type.

[0260] Optional terminal types include: RedCap terminals, LPWA terminals, XR terminals, satellite terminals, CPEs, FWAs, AIoT devices, robots, etc.

[0261] For example, in scenarios where different terminal types support different SSBs, a specific type of terminal (such as an LPWA terminal) uses MIB1 as its SSB, while another specific type of terminal (such as a CPE terminal) uses MIB2.

[0262] The information transmission method provided in this application embodiment can determine the type and / or size and / or existence / sending of the first SSB or the first MIB according to the type of the terminal. By supporting different SSB / MIB types or sizes, the complexity of SSB detection, the size of information carried by the SSB, and the reliability of the SSB can be balanced, which can meet the needs of different application scenarios.

[0263] In addition, embodiments of this application also support carrying additional fourth information through variable MIB / SSB size and multiple MIB / SSB types, as well as the presence / transmission of specific types, which can reduce signaling overhead.

[0264] In some embodiments, the first information is further associated with fourth information; or, the method further includes: determining the fourth information based on the first information;

[0265] The fourth information includes at least one of the following:

[0267] The configuration and / or definition of a first search space, the first search space being used to search for at least one of the following: the fourth SSB, the second system message, and the scheduling control channel corresponding to the fourth SSB or the second system message;

[0268] The configuration and / or definition of a second control resource set, which is used to search for WUS feedback signals or scheduling control channels corresponding to the WUS feedback signals;

[0269] The configuration and / or definition of a second search space, which is used to search for WUS feedback signals or scheduling control channels corresponding to the WUS feedback signals;

[0270] The configuration and / or definition of a third control resource set, the third control resource set being used to search for at least one of the following: random access response message, Msg4, MsgB, and the scheduling control channel corresponding to the random access response message, Msg4, or MsgB;

[0273] The configuration and / or definition of a fourth search space, which is used to search for paging messages or the scheduling control channel corresponding to the paging messages;

[0274] The third indication information is used to indicate whether WUS triggering is required or not.

[0275] The fourth indication information is used to indicate whether a subsequent SSB exists or not.

[0276] PBCH encoding, modulation scheme and / or waveform.

[0277] The information in the second system may be the same as or different from the information in the first system.

[0278] It is understood that the first information may also be associated with at least one of the following: different control resource sets (e.g., referred to as CORESET#0) or search spaces (e.g., referred to as SS#0) for searching the fourth SSB (e.g., the SSB following the first SSB) or the second system message (e.g., SIB1) of the cell where the fourth SSB is located, or the scheduling control channel corresponding to the fourth SSB or the second system message; different control resource sets or search spaces for searching the WUS feedback signal or the scheduling control channel corresponding to the WUS feedback signal; different control resource sets (e.g., referred to as CORESET#1) or search spaces (e.g., referred to as SS#1) for searching the random access response message or the fourth random access message Msg4 in a four-step random access process or the second random access message MsgB in a two-step random process, or the scheduling control channel corresponding to the random access response message, Msg4, or MsgB; different control resource sets or search spaces for searching the paging message or the scheduling control channel corresponding to the paging message.

[0279] Optionally, the first information can also indicate whether the first SSB or subsequent SSBs require WUS triggering. That is, whether the first SSB or subsequent SSBs are transmitted on demand.

[0280] Optionally, the first signal can also indicate whether a subsequent SSB exists.

[0281] Optionally, the first signal may also indicate different PBCH codes, PBCH modulation schemes, and / or PBCH waveforms.

[0282] In some embodiments, the method further includes at least one of the following:

[0283] The terminal sends a first WUS, and the relevant information of the first WUS is provided by the second SSB;

[0284] The terminal sends a first WUS, which is used to request a first SSB.

[0285] For scenarios that support at least two levels of SSB search, the terminal can send the first WUS based on the relevant information of the first WUS provided by the second SSB.

[0286] In scenarios where there is only a first-level SSB search, the terminal requests the first SSB through the first WUS.

[0287] For example, in scenarios supporting at least two levels of SSB search, the first-level SSB uses MIB1, the second-level SSB uses MIB2, or the first level may not have a MIB, only a synchronization sequence, such as PSS / SSS. The first level can have a longer period, and / or the second level can have a shorter period. Alternatively, the second-level SSB can be optional. Optionally, the second-level SSB is triggered on-demand transmission via a specific signal, such as the WUS signal. Information related to the WUS can be provided by at least a portion of the signals from the first-level SSB.

[0288] Optionally, the relevant information of the first WUS includes at least one of the following: WUS resources; the resource cell where the WUS resources are located; timing advance (TA); frequency offset; time compensation; frequency compensation; time change rate; frequency change rate; ephemeris information; WUS period; subcarrier spacing of the WUS; search time window information for the WUS feedback signal; threshold for the downlink measurement values ​​required for WUS to be transmitted; relevant information for WUS sequence generation; maximum transmit power; number of transmission opportunities for WUS frequency domain multiplexing; target receive power of WUS; maximum number of retransmissions of WUS; power ramp-up step size of WUS; number of WUS transmission repetitions; relevant information for the repetition resource determination window of WUS transmission; association information between WUS and target SSB; WUS type; duplex configuration; whether access to the cell is allowed; subcarrier spacing of the first SSB; power configuration information of the first SSB; frequency location information of the scheduling and control channel corresponding to the target SSB; the target SSB includes the first SSB and / or the second SSB.

[0289] Optionally, the WUS allows the transmission of a threshold for the required downlink measurements, including at least one of the following:

[0290] A first threshold value is set, allowing the terminal to send WUS if the measured value of the second SSB is less than or does not exceed the first threshold value;

[0291] A second threshold is set so that if the measured value of the second SSB is greater than the first threshold and less than or not greater than the second threshold, the terminal is allowed to send a WUS and / or search for the first SSB; if the measured value of the second SSB exceeds the second threshold, the terminal does not send a WUS and / or abandons the search for the first SSB.

[0292] The second SSB can be understood as the first-level SSB, and the first SSB can be understood as the second-level SSB. If the measured value of the first-level SSB is less than or does not exceed the first threshold, the terminal is allowed to send WUS, or the terminal sends WUS.

[0293] If the measured value of the first-level SSB is greater than the first threshold and less than or not greater than the second threshold, the terminal is allowed to send WUS and / or search for the second-level SSB.

[0294] If the measured value of the first-level SSB exceeds the second threshold, it indicates that the communication quality of the cell corresponding to the first-level SSB is good, allowing the terminal not to send WUS and / or to give up searching for the first SSB.

[0295] Optionally, the association information between the WUS and the target SSB includes at least one of the following: association ratio; association period; and the set of associated SSBs.

[0296] It is understandable that the relationship between the first WUS and the target SSB is reflected in the ratio, period, and SSB set.

[0297] In some embodiments, the structures of the SSBs corresponding to different sizes of MIBs may be the same or different.

[0298] The SSB structure can be the same or different for different MIB sizes. If the structure is the same, UE implementation is relatively simple. The main problem is that the reliability of large MIBs will be relatively poor due to the higher bit rate, making it suitable for scenarios with low coverage requirements, such as energy-saving scenarios. If the structure is different, it can ensure good performance for SSBs of different payload sizes, making it suitable for scenarios with high coverage requirements.
