Technical Field

[0004] With the evolution of communication technology, for example, 6G will have more application scenarios than 4G and 5G, and will require support for a wide range of terminal types. This may require support for multiple types of objects (such as synchronization signals and broadcast signals). These objects may have different characteristics (such as periodicity, bandwidth, search complexity, time-frequency domain resources, information carried, and generation method), and may not be limited to half-frame windows. Because different objects may not have the same periodicity, time-frequency domain resources, and other characteristics, and may not be limited to half-frame windows, the current mapping method for reference signal sequences cannot meet the needs of different types of objects. Therefore, determining the mapping method for reference signal sequences for different types of objects is a challenge that needs to be addressed. Summary of the Invention

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0066] To facilitate a better understanding of the embodiments of the present application, the embodiments of the present application are described using a synchronization signal block (SSB) as an example.

[0067] In order for the terminal to search for a reasonable cell and synchronize with the selected cell, the network usually needs to broadcast a synchronization signal and provide certain master information about the cell. Specifically, the SSB can be shown in Figure 2. The synchronization signal (SS) mainly includes the primary synchronization signal (PSS) and the secondary synchronization signal (SSS). Among them, the PSS and SSS can occupy 127 subcarriers, and the physical broadcast channel (PBCH) on both sides of the SSS can occupy 4 physical resource blocks (PRBs). The PBCH can carry the main system information, also known as the master information block (Master Information Block).

[0068] It should be noted that SSB can also be called synchronization signal / physical broadcast channel block (SS / PBCH block).

[0069] To facilitate a better understanding of the embodiments of the present application, some processes in the PBCH generation method are described.

[0070] The 5G PBCH contains 32 bits and does not change every 80ms.

[0071] 1. The upper layer generates the 24 bits contained in the PBCH.

[0072] 2. The physical layer generates 8 bits contained in the PBCH. These 8 bits mainly contain information related to the SSB merging within 80ms, such as the 1-4 least significant bits (LSB) system frame number (SFN), the 3-bit most significant bit (MSB) SSB index (for low frequencies, the 3 bits corresponding to the 3-bit MSB SSB index are not used to carry the SSB index, but are still generated by the physical layer) and the half frame indicator (HFI).

[0073] 3. Concatenate the bits generated by the upper layer and the physical layer into a 32-bit PBCH payload;

[0074] 1) Perform first-layer scrambling: Some bits generated by the physical layer are not scrambled, that is, the 3MSB SSB index (or the 3 bits corresponding to the low frequency), HFI, and the 2nd / 3rd LSB SFN of the PBCH are not scrambled, but the remaining bits of the PBCH payload are scrambled.

[0075] A. In the first layer of scrambling, the scrambling code sequence is related to the physical cell identifier (PCI) and the second / third LSB SFN carried in the PBCH;

[0076] B. Since the second / third LSB SFN is not scrambled for the first time, the second / third LSB SFN and thus the first scrambling code can be determined after PBCH decoding. Descrambling can be done directly without multiple assumptions and attempts, reducing complexity.

[0077] 2) Generate a cyclic redundancy check (CRC) and perform channel coding on the PBCH payload.

[0078] A. The basic idea of ​​the first layer of scrambling is: do not scramble the different bit parts of the contents of two SSBs that can be merged, and scramble the same parts of the contents of two SSBs that can be merged.

[0079] B. Since bits with different contents are not scrambled for the first time, the user can determine the position of the unscrambled bits in the encoded bit string before decoding the PBCH payload. After receiving SSBs in multiple cycles, the user can directly merge the bits with the same SSB content to improve the decoding success rate.

[0080] 3) Perform the second layer of scrambling: scramble the bits after channel coding collectively.

[0081] A. In the second layer of scrambling, the scrambling sequences corresponding to different SSBs are only related to the SSB index or HFI carried in the PCI and the Demodulation Reference Signal (DMRS).

[0082] B. Therefore, when the user performs the second descrambling, the second-layer scrambling code sequence can be directly derived based on the relevant information obtained during the DMRS and synchronization signal detection process, eliminating the need for multiple assumptions and attempts, thereby reducing complexity.

[0083] 4. Quadrature Phase Shift Keying (QPSK) modulation, resource mapping, etc.

[0084] Based on the above analysis, it can be seen that the two-layer scrambling design can ensure that the terminal can decode the PBCH in a short time with low complexity.

[0085] To facilitate a better understanding of the embodiments of the present application, the synchronization grid and GSCN are explained.

[0086] 5G NR defines a synchronization raster for the 0-100 GHz frequency band. The synchronization raster is numbered as the GSCN. Base stations can transmit SSBs (also known as synchronization signals / physical broadcast signal blocks (SS / PBCH blocks)) on the synchronization raster. The location and calculation of the GSCN in different frequency domains are shown in Table 1.

[0087] For example, when GSCN=2, it can be deduced that N=1, M=1, and thus the corresponding frequency domain position is 1250 kHz.

[0088] Table 1

[0089] According to NR's frequency domain planning, supportable channel bandwidths (bands) are defined for different operating frequency bands based on different subcarrier spacings (SCS). Table 2 below provides information about the channel bandwidth for band n1. For example, for band n1, when the SCS of the transmitted data / control signal is 15 kHz, the minimum channel bandwidth for this band is 5 MHz.

[0090] Table 2

[0091] NR defines GSCN ranges and step sizes for different bands. The step size is the difference between the GSCN numbers of two adjacent synchronization grids belonging to the band. For example, the GSCN range for n41 is 6246–6714. With a step size of 3, the GSCN numbers within the n41 range are 6246, 6249, ..., 6714.

[0092] It should be noted that there may be frequency overlap between different bands. For example, as shown in Table 3 below, band n38 and band n41 overlap, but the GSCN step sizes are different.

[0093] Table 3

[0094] To facilitate a better understanding of the embodiments of the present application, a channel raster is described.

[0095] NR defines a channel raster, on which base stations can deploy channels. Channel rasters can be 100kHz, 15kHz, 30kHz, 60kHz, or 120kHz.

[0096] For example, in Table 4 below, the channel raster for band n1 is 100 kHz. The NR-ARFCN numbers corresponding to its uplink frequency domain range are 384000–396000, and the NR-ARFCN numbers corresponding to its downlink frequency domain range are 422000–434000. An NR-ARFCN number can also be used to indicate a frequency domain location.

[0097] Table 4

[0098] It should be noted that there may be frequency overlap between different bands, for example, band n38 and band n41. As shown in Table 5 below, although these two bands overlap, the step sizes of NR-ARFCN are different.

[0099] Table 5

[0100] In 5G systems, SSB is limited to a half-frame window, so HFI also has special designs in the generation and scrambling process. For example, the terminal searches for the synchronization signal on the synchronization raster. For a given SCS, the interval between synchronization rasters on the same frequency band is fixed.

[0157] In some embodiments, when the mapping manner of the reference signal sequence of the first object is related to the first information, the mapping position of the reference signal sequence of the first object can be determined based on the first information.

[0158] In some embodiments, when the mapping manner of the reference signal sequence of the first object is related to the first information, the mapping position of the reference signal sequence of the first object is determined based on the first position information;

[0159] The first position information includes at least one of the following: a first reference position, a first offset, a first starting position, a first adjustment step, a first synchronization grid, and a first channel grid;

[0160] The first location information is related to the first information.

[0161] In this embodiment, the location where the reference signal sequence of the first object is mapped, determined based on the first location information, is the location where the reference signal sequence of the first object is actually mapped, thereby reducing interference between reference signal sequences of different objects.

[0162] Optionally, the first location information is agreed upon by a protocol, or the first location information is configured by a network side.

[0163] Exemplarily, if the first information is associated with the type of the first object, or the first information includes the type of the first object, assuming that the first object is SSB, the offset corresponding to the SSB of type A is frequency domain shift1, and the offset corresponding to the SSB of type B is frequency domain shift2, then the reference signal sequences of the two types of objects can be mapped to different resource elements (REs), so that the reference signal sequences of the two types of objects do not interfere with each other.

[0164] In some embodiments, the first location information is related to the first information and includes:

[0165] The first position information is determined based on the value of at least part of the bits of the first information; or,

[0166] The first location information is determined based on a value of at least some bits of the first information and an identifier of at least one physical resource. Optionally, each of the at least one physical resource is one of the following: a cell, a carrier, a BWP, a resource pool, a frequency band, or a subband. Exemplarily, the cell identifier may be a PCI.

[0167] In some embodiments, when the first position information is determined based on values ​​of at least some bits of the first information, the first position information is determined based on a result of values ​​of at least some bits of the first information mod C;

[0168] Wherein, C represents the frequency domain interval between two adjacent reference signal resources, or C represents the value of the frequency domain interval between two adjacent reference signal resources + 1, or C represents the interval between two adjacent objects, or C represents the total number of object types, and mod represents a modulo operation;

[0169] The types of the two objects are the same as the type of the first object.

[0170] For example, when the first position information is determined based on the value of at least some bits of the first information, the first position information=the value of at least some bits of the first information mod C.

[0171] It should be understood that if C=1, it means that C is not actually modulated.

[0172] In some embodiments, when the first location information is determined based on the value of at least some bits of the first information and the identifier of the at least one physical resource, the first location information is determined based on a result of (the value of at least some bits of the first information mod C)*D+ID mod D, or the first location information is determined based on a result of the value of at least some bits of the first information mod C+(ID mod D)*C, or the first location information is determined based on a result of [(the value of at least some bits of the first information mod C)*D+ID mod D] mod E, or the first location information is determined based on a result of [(the value of at least some bits of the first information mod C+(ID mod D)*C)] mod E;

[0173] Wherein, C represents the frequency domain interval between two adjacent reference signal resources, or C represents the value of the frequency domain interval between two adjacent reference signal resources + 1, or C represents the interval between two adjacent objects, or C represents the total number of object types;

[0174] Wherein, D represents the frequency domain interval between two adjacent reference signal resources, or D represents the value of the frequency domain interval between two adjacent reference signal resources + 1, or D represents the interval between two adjacent objects, or D represents the total number of object types;

[0175] Wherein, E represents the frequency domain interval between two adjacent reference signal resources, or, E represents the value of the frequency domain interval between two adjacent reference signal resources + 1, or, E represents the interval between two adjacent objects, or, E represents the total number of object types;

[0176] Wherein, ID represents the identifier of the at least one physical resource, the types of the two objects are the same as the type of the first object, and mod represents a modulo operation.

[0177] For example, when the first location information is determined based on the value of at least some bits of the first information and the identifier of at least one physical resource, the first location information = (the value of at least some bits of the first information mod C)*D+ID mod D.

[0178] For another example, when the first location information is determined based on the value of at least some bits of the first information and the identifier of at least one physical resource, the first location information = the value of at least some bits of the first information mod C + (ID mod D)*C.

[0179] For another example, when the first location information is determined based on the value of at least part of the bits of the first information and the identifier of at least one physical resource, the first location information = [(the value of at least part of the bits of the first information mod C)*D+ID mod D]mod E.

[0180] For another example, when the first location information is determined based on the value of at least part of the bits of the first information and the identifier of at least one physical resource, the first location information = [(the value of at least part of the bits of the first information mod C + (ID mod D)*C)] mod E.

[0181] It should be understood that if C=1, it means that C is not actually modeled; if D=1, it means that D is not actually modeled; and if E=1, it means that E is not actually modeled.

[0182] In some embodiments, if the first information is associated with the type of the first object, the first information includes type indication information; wherein the type indication information is used to indicate the type of the first object. In this embodiment, the mapping manner of the reference signal sequence of different types of objects can be distinguished.

[0183] In some embodiments, if the first information is associated with configuration information of the first object, the first information includes configuration indication information; wherein the configuration indication information is used to indicate the configuration of the first object. In this embodiment, the mapping method of the reference signal sequence of objects with different configurations can be distinguished.

[0184] In some embodiments, when the first information includes type indication information, the first object supports at least two types, or the first object is configured with at least two types, or the first object allows at least two types; or the first object is an object supported by a terminal or network that supports at least two types of objects. In this embodiment, the mapping manner of reference signal sequences of different types of objects can be differentiated.

[0185] In some embodiments, when the first information includes configuration indication information, the first object supports at least two configurations, or the first object is configured with at least two configurations, or the first object allows at least two configurations. In this embodiment, the mapping manner of the reference signal sequence of objects with different configurations can be distinguished.

[0186] In some embodiments, if the first information is associated with the type of the first object, and the first object supports at least two types, or the first object is configured with at least two types, or the first object allows at least two types, the first information is the intersection, union, exclusive-or result, summation, or AND result of the information bits associated with the at least two types, respectively. In this embodiment, the mapping method of the reference signal sequence of different types of objects can be distinguished.

[0187] In some embodiments, if the first information is associated with the configuration information of the first object, and the first object supports at least two configurations, or the first object is configured with at least two configurations, or the first object allows at least two configurations, the first information is the intersection of the information bits respectively associated with the at least two configurations, or the first information is the union of the information bits respectively associated with the at least two configurations, or the first information is the exclusive OR result of the information bits respectively associated with the at least two configurations, or the first information is the sum result of the information bits respectively associated with the at least two configurations, or the first information is the AND result of the information bits respectively associated with the at least two configurations. In this embodiment, the mapping method of the reference signal sequence corresponding to objects with different attributes can be distinguished.

[0188] In some embodiments, the first information is only related to a specific type of object, or a specific type of object is configured with the first information. In other words, the first object can be an object of a specific type. For example, for an SSB used for cell search and downlink synchronization, the mapping method of the corresponding reference signal sequence is related to the first information; for an SSB used for beam management or channel state information acquisition, the mapping method of the corresponding reference signal sequence is not related to the first information, or the SSB is not configured with the first information.

[0189] In some embodiments, when the first information is associated with configuration information of the first object, the first information includes an association between the configuration of the first object and a mapping method of a reference signal sequence of the first object. In this embodiment, the mapping methods of reference signal sequences of objects with different configurations can be distinguished.

[0190] Optionally, when the first information includes an association between the configuration of the first object and a mapping manner of a reference signal sequence of the first object, the mapping manner of the reference signal sequence of the first object may be determined based on the configuration of the first object.

[0191] In some embodiments, when the first information is associated with the transmission period or TTI of the first object, the first information includes at least part of the valid bits of the frame information (such as the system frame number (SFN)) associated with the transmission period or TTI of the first object.

[0192] For example, if the transmission period of the first object is 20 ms or the TTI is 80 ms, the first information is at least one bit of the second and third least significant bits (LSB) SFN.

[0193] For another example, if the transmission period of the first object is 20 ms or the TTI is 40 ms, the first information is at least one bit in the second LSB SFN.

[0194] For another example, if the transmission period of the first object is 20 ms or the TTI is 160 ms, the first information is at least one bit of the 2nd, 3rd, and 4th LSB SFNs.

[0195] For another example, if the transmission period of the first object is 10 ms or the TTI is 80 ms, the first information is at least one bit of the 1st, 2nd, and 3rd LSB SFNs.

[0196] For another example, if the transmission period of the first object is 10 ms or the TTI is 40 ms, the first information is at least one bit in the first and second LSB SFNs.

[0197] For another example, if the transmission period of the first object is 10 ms or the TTI is 20 ms, the first information is at least one bit in the 1st LSB SFN.

[0198] In some embodiments, the transmission period or TTI of the first object may be changed or activated or deactivated or updated.

[0199] Optionally, the transmission period / TTI of the first object is changed or activated or deactivated or updated because at least part of the first object (on demand) is (re)configured or activated or deactivated or released or overwritten.

[0200] For example, the first object is SSB. Assume that the SSB transmission period is 10ms (considering all SSBs, including on-demand SSBs), the TTI is 80ms, and all SSBs with even periods are on-demand SSBs. If on-demand SSB is not activated, the actual SSB transmission period is twice that when on-demand SSB is activated, that is, 20ms. The first information is the 2nd and 3rd LSB SFNs. If on-demand SSB is activated, the actual SSB transmission period is 10ms. The first information is at least one bit of the 1st and 2nd LSB SFNs.

[0201] Optionally, the transmission period / TTI of the first object is changed because the transmission period / TTI is configured or reconfigured. Exemplarily, the default transmission period / TTI of the first object is switched to a transmission period / TTI actually supported by the network, or the transmission period / TTI of the first object is reconfigured through a system message change or Radio Resource Control (RRC).

[0202] In some embodiments, when the first information is associated with a transmission period or a TTI of the first object, the first information satisfies one of the following conditions:

[0203] associated with the changed transmission period or TTI;

[0204] Associated with the activated transmission period or TTI;

[0205] associated with the updated transmission period or TTI;

[0206] associated with a default transmission period or TTI;

[0207] Associated with all configured transmission periods or TTIs;

[0208] associated with a specific transmission period or TTI among all configured transmission periods or TTIs;

[0209] Associated with the transmission period or TTI with the largest length among all configured transmission periods or TTIs;

[0210] Associated with the transmission period or TTI with the smallest length among all configured transmission periods or TTIs.

[0211] Optionally, the specific transmission period or TTI may be agreed upon by a protocol, or the specific transmission period or TTI may be configured by the network side, or the specific transmission period or TTI is the transmission period or TTI with the smallest index or number among all configured transmission periods or TTIs, or the specific transmission period or TTI is the transmission period or TTI with the largest index or number among all configured transmission periods or TTIs.

[0212] Exemplarily, the first object is an SSB. If the transmission period / TTI can be changed, activated, deactivated, or updated, the first information can be associated with the (certain / maximum / minimum / overall) transmission period / TTI corresponding to all configured SSBs. For example, for on-demand SSB, regardless of whether it is activated, the corresponding SSB period still considers all SSBs. In this case, the determination of the SFN bit is not affected by whether the on-demand SSB is activated.

[0213] In some embodiments, when the first information is associated with the transmission period or TTI of the first object, if the information bits (N1 bits) associated with the updated or changed or activated or deactivated transmission period or TTI are less than the information bits (N2 bits) associated with the current transmission period or TTI, or the information bits (N1 bits) associated with the updated or changed or activated or deactivated transmission period or TTI are a subset of the information bits (N2 bits) associated with the current transmission period or TTI, the first information is one of the following:

[0214] Information bits associated with the current transmission period or TTI;

[0215] Information bits associated with the updated or changed or activated or deactivated transmission period or TTI;

[0216] Information bits associated with the default transmission period or TTI;

[0217] The remaining information bits after a portion of the information bits associated with the current transmission period or TTI is truncated;

[0218] A first specific portion of information bits associated with the current transmission period or TTI;

[0219] The information bits remaining after a portion of the information bits associated with the default transmission period or TTI are truncated;

[0220] A first specific portion of information bits associated with a default transmission period or TTI;

[0221] The information bits associated with the updated or changed or activated or deactivated transmission period or TTI are filled with at least one bit to obtain the information bits;

[0222] The remaining information bits are obtained by truncating a portion of the information bits associated with the updated or changed or activated or deactivated transmission period or TTI.

[0223] It should be noted that the current transmission period or TTI may be a transmission period or TTI before being updated, changed, activated, or deactivated.

[0224] Exemplarily, the first information is the information bits remaining after a portion of the information bits associated with the current transmission period or TTI is truncated, and the remaining information bits after the portion is truncated are N1 bits, wherein the truncated bits are high bits and the retained bits are low bits.

[0225] Exemplarily, the first information is the information bits remaining after a portion of the information bits associated with the default transmission period or TTI is truncated, and the remaining information bits after the portion is truncated are N1 bits; optionally, the truncated bits are high bits and the retained bits are low bits.

[0226] Exemplarily, the first information is a first specific portion of information bits associated with the current transmission period or TTI, wherein the first specific portion is N1 bits; optionally, the first specific portion is a low bit.

[0227] Exemplarily, the first information is a first specific portion of information bits associated with a default transmission period or TTI, wherein the first specific portion is N1 bits; optionally, the first specific portion is a low bit.

[0228] Exemplarily, the first information is obtained by filling at least one bit in front of the information bit associated with the updated or changed or activated or deactivated transmission period or TTI, for example, filling 0 or 1 in front of the information bit associated with the updated or changed or activated or deactivated transmission period or TTI to obtain N2 bits.

[0229] In some embodiments, when the first information is associated with a transmission period or TTI, if the information bits (N3 bits) associated with the updated or changed or activated or deactivated transmission period or TTI are more than the information bits (N4 bits) associated with the current transmission period or TTI, or the information bits (N4 bits) associated with the current transmission period or TTI are a subset of the information bits (N3 bits) associated with the updated or changed or activated or deactivated transmission period or TTI, the first information is one of the following:

[0230] Information bits associated with the current transmission period or TTI;

[0231] Information bits associated with the updated or changed or activated or deactivated transmission period or TTI;

[0232] Information bits associated with the default transmission period or TTI;

[0233] The remaining information bits after a portion of the information bits associated with the updated or changed or activated or deactivated transmission period or TTI is truncated;

[0234] a second specific portion of information bits associated with the updated or changed or activated or deactivated transmission period or TTI;

[0235] The information bits remaining after a portion of the information bits associated with the default transmission period or TTI are truncated;

[0236] A second specific portion of information bits associated with a default transmission period or TTI;

[0237] The default transmission period or TTI-associated information bits are padded with at least one bit to obtain the information bits;

[0238] The information bits associated with the current transmission period or TTI are padded with at least one more bit to obtain the information bits;

[0239] The information bits remaining after a portion of the information bits associated with the current transmission period or TTI are truncated.

[0240] Exemplarily, the first information is the information bits remaining after a part of the information bits associated with the updated or changed or activated or deactivated transmission period or TTI is cut off, and the remaining information bits after the part is cut off are N4 bits, of which the cut bits are high bits and the retained bits are low bits.

[0241] Exemplarily, the first information is the information bits remaining after a portion of the information bits associated with the default transmission period or TTI is truncated, and the remaining information bits after the portion is truncated are N4 bits; optionally, the truncated bits are high bits and the retained bits are low bits.

[0242] Exemplarily, the first information is the second specific part of the information bits associated with the transmission period or TTI of the updated or changed or activated or deactivated first object, wherein the second specific part is N4 bits; optionally, the second specific part is a low bit.

[0243] Exemplarily, the first information is a second specific part of the information bits associated with the default transmission period or TTI, wherein the second specific part is N4 bits; optionally, the second specific part is a low bit.

[0244] Exemplarily, the first information is the information bit associated with the default transmission period or TTI and then filled with at least one bit to obtain the information bit. For example, 0 or 1 is filled before the information bit associated with the default transmission period or TTI to obtain N3 bits.

[0245] Exemplarily, the first information is the information bit associated with the current transmission period or TTI and then filled with at least one bit to obtain the information bit, for example, 0 or 1 is filled before the information bit associated with the current transmission period or TTI to obtain N3 bits.

[0246] In some embodiments, when the first information is associated with the transmission period or TTI of the first object, if the first object supports at least two transmission periods or TTIs, the first information is the intersection or union or exclusive OR result or sum result or AND result of the information bits respectively associated with the at least two transmission periods or TTIs.

[0247] Exemplarily, the first object supports two transmission periods or TTIs, wherein the transmission period of the first object is 20ms or TTI is 160ms, and the transmission period is 10ms or TTI is 40ms, and the first information is at least one bit of the 1st, 2nd, 3rd and 4th LSB SFN.

[0248] In some embodiments, different types of objects may independently determine the first information according to their own transmission time windows or transmission time limits.

[0249] For example, if the transmission period or TTI of the first object is 5 ms, the first information is a 1-bit HFI.

[0250] For example, if the transmission period or TTI of the first object is 2 ms, the first information is 4-bit indication information, and the indication information indicates the specific position of the 2 ms in a frame.

[0251] In some embodiments, when the first information is associated with a transmission time window or a transmission time limit of the first object, the first information satisfies one of the following:

[0252] associated with a changed transmission time window or transmission time limit;

[0253] associated with an activated transmission time window or transmission time limit;

[0254] associated with the updated transmission time window or transmission time limit;

[0255] associated with a default transmission time window or transmission time limit;

[0256] associated with an initial transmission time window or transmission time limit;

[0257] Associated with the current transmission time window or transmission time limit.

[0258] In some embodiments, if the transmission time window or transmission time limit of the first object is X, the transmission period or TTI of the first object is Y, the number of bits of the first information is related to the result of log2(Y / X), and both X and Y are positive numbers. Optionally, the number of bits of the first information is the smallest integer greater than log2(Y / X).

[0259] In some embodiments, when the first information is associated with the transmission time window or transmission time limit of the first object, if the first object supports at least two transmission time windows or transmission time limits, the first information is the intersection or union or exclusive OR result or sum result or AND result of the information bits respectively associated with the at least two transmission time windows or transmission time limits, or the first information is the information bit with the largest number of bits among the information bits respectively associated with the at least two transmission time windows or transmission time limits.

[0260] Exemplarily, if the first object supports a first type of transmission time window or transmission time limit and a second type of transmission time window or transmission time limit, where the first type of transmission time window or transmission time limit is 5ms and the second type of transmission time window or transmission time limit is 2ms, then the number of bits of the first information is max(1,4)=4bit.

[0261] In some embodiments, when the first information is associated with the index or number of the first object, if the first object supports at least two indexes or numbers, the first information is the intersection or union or XOR result or sum result or AND result of the information bits respectively associated with the at least two indexes or numbers, or the first information is the information bit with the largest number of bits among the information bits respectively associated with the at least two indexes or numbers.

[0262] For example, the first object is SSB, which can support two indexes (index) of type A and type B. Type A supports up to 8 SSBs, and the index information requires 3 bits. Type B supports up to 16 SSBs, and the index requires 4 bits. The mapping method of the reference signal sequence corresponding to type A is related to at least some of the bits in the 3-bit index, and the mapping method of the reference signal sequence corresponding to type B is related to at least some of the bits in the 4-bit index.

[0263] In some embodiments, when the first information is associated with the index or number of the first object, if the first object supports at least two index upper limits or number upper limits, the first information is the intersection or union or XOR result or sum result or AND result of the information bits respectively associated with the at least two index upper limits or number upper limits, or the first information is the information bit with the largest number of bits among the information bits respectively associated with the at least two index upper limits or number upper limits.

[0264] It should be noted that the "index upper limit" can also be understood as the maximum number of indexes, and the "number upper limit" can also be understood as the maximum number of numbers.

[0265] For example, the first object is SSB, which can support two indexes (index) of type A and type B. Type A supports up to 8 SSBs, and the index information requires 3 bits. Type B supports up to 16 SSBs, and the index requires 4 bits. The mapping method of the reference signal sequence corresponding to type A / B is related to at least part of the bits in the 4-bit index.

[0266] In some embodiments, when the mapping manner of the reference signal sequence of the first object is related to the second information, the mapping position of the reference signal sequence of the first object can be determined based on the second information.

[0267] In some embodiments, when the mapping manner of the reference signal sequence of the first object is related to the second information, the mapping position of the reference signal sequence of the first object is determined based on the second position information;

[0268] The second position information includes at least one of the following: a second reference position, a second offset, a second starting position, a second adjustment step, a second synchronization grid, and a second channel grid;

[0269] The second location information is related to the second information.

[0270] Optionally, the second location information is agreed upon by a protocol, or the second location information is configured by a network side.

[0271] For example, in a case where a cell supports multiple frequency bands, the reference signal sequence mapping of the first object on each band can be different. For example, a time / frequency domain offset (shift) associated with the band can be introduced. The reference signal sequence mapping of the first object of such a multi-band cell uses a shift set. Furthermore, different shift sets can be used for different cells containing multiple bands. The shift set can, for example, depend on the PCI. This reduces interference between reference signal sequences between such cells.

[0272] In some embodiments, the mapping method of the reference signal sequence of the first object is determined based on but not limited to at least one of the following: the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object.

[0273] In this embodiment, the mapping method of the reference signal sequence of the first object can be determined based on at least one of the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, so that the mapping method of the reference signal sequence of the first object can be accurately determined.

[0274] In some embodiments, the first information is associated with at least one of the following: the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position that the first object allows mapping, and the channel grid corresponding to the candidate frequency domain position that the first object allows mapping.

[0275] Exemplarily, if the first information is associated with the type of the first object, or the first information includes the type of the first object, at least one of the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the type of the first object, thereby further determining the mapping method of the reference signal sequence of the first object.

[0276] Exemplarily, if the first information is associated with the configuration information of the first object, or the first information includes the configuration information of the first object, the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and at least one of the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the configuration information of the first object, so as to further determine the mapping method of the reference signal sequence of the first object.

[0277] Exemplarily, if the first information is associated with the transmission period or TTI of the first object, or the first information includes the transmission period or TTI of the first object, the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and at least one of the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the transmission period or TTI of the first object, so as to further determine the mapping method of the reference signal sequence of the first object.

[0278] Exemplarily, if the first information is associated with the transmission time window or transmission time limit of the first object, or the first information includes the transmission time window or transmission time limit of the first object, the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the transmission time window or transmission time limit of the first object, thereby further determining the mapping method of the reference signal sequence of the first object.

[0279] Exemplarily, if the first information is associated with the index or number of the first object, or the first information includes the index or number of the first object, at least one of the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the index or number of the first object, thereby further determining the mapping method of the reference signal sequence of the first object.

[0280] In some embodiments, the second information is associated with at least one of the following:

[0281] The candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object.

[0282] Exemplarily, if the second information includes the frequency band corresponding to the type of the first object, the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and at least one of the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the frequency band corresponding to the type of the first object, thereby further determining the mapping method of the reference signal sequence of the first object.

[0283] Exemplarily, if the second information includes the frequency band range corresponding to the type of the first object, the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and at least one of the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the frequency band range corresponding to the type of the first object. Thus, the mapping method of the reference signal sequence of the first object can be further determined.

[0284] Exemplarily, if the second information includes the resource type corresponding to the type of the first object, the candidate frequency domain position corresponding to the first object, the interval between adjacent candidate frequency domain positions corresponding to the first object, the offset of the candidate frequency domain position corresponding to the first object, the starting position of the candidate frequency domain position corresponding to the first object, the synchronization grid corresponding to the candidate frequency domain position allowed to be mapped by the first object, and at least one of the channel grid corresponding to the candidate frequency domain position allowed to be mapped by the first object can be determined based on the resource type corresponding to the type of the first object, thereby further determining the mapping method of the reference signal sequence of the first object.

[0285] In some embodiments, assuming the first object is a synchronization signal or a broadcast signal, the synchronization signal or broadcast signal can be mapped based on the binding relationship between the operating frequency band and the frequency domain resource location predefined by the protocol, which facilitates the terminal's search during initial access. As shown in Table 6, taking band 38 as an example, the frequency domain locations where the synchronization signal or broadcast signal may be used for transmission / reception / search are defined. These locations are part of the GSCN, but the adjustment step size (step size) is related to the type of synchronization signal or broadcast signal. For a certain type of synchronization signal or broadcast signal, two adjacent candidate frequency domain locations are the locations corresponding to two GSCNs, and the two GSCNs are separated by X numbers, that is, step size = X; for another type of synchronization signal or broadcast signal, two adjacent candidate frequency domain locations are the locations corresponding to two GSCNs, and the two GSCNs are separated by Y numbers, that is, step size = Y. For example, the step size corresponding to the RedCap synchronization signal or broadcast signal may be relatively large, thereby effectively reducing the search complexity. This embodiment is not only applicable to band 38 but also to any band.

[0286] Table 6

[0287] In some embodiments, assuming that the first object is a synchronization signal or a broadcast signal, the frequency domain positions at which the synchronization signal or broadcast signal may be used for transmission / reception / search are defined. These positions are part of the Absolute Radio-Frequency Channel Number (ARFCN), but the adjustment step size is related to the type of the synchronization signal or broadcast signal. For a certain type of synchronization signal or broadcast signal, two adjacent candidate frequency domain positions are positions corresponding to two ARFCNs, and the two ARFCNs are separated by X numbers, that is, step size = X; for another type of synchronization signal or broadcast signal, two adjacent candidate frequency domain positions are positions corresponding to two ARFCNs, and the two ARFCNs are separated by Y numbers, that is, step size = Y. For example, the step size corresponding to the synchronization signal or broadcast signal of RedCap may be relatively large, thereby effectively reducing the search complexity.

[0288] In some embodiments, assuming the first object is a synchronization signal or a broadcast signal, mapping of the synchronization signal or broadcast signal can be performed based on the protocol-predefined binding relationship between the operating frequency band and the frequency domain resource location, facilitating the terminal's search during initial access. As shown in Table 7, using band 38 as an example, frequency domain locations where synchronization signals or broadcast signals may be transmitted / received / searched are defined. These locations are part of the GSCN, but the offsets are dependent on the type of synchronization signal or broadcast signal. This embodiment is applicable not only to band 38 but to any band.

[0289] For a certain synchronization signal or broadcast signal type, two adjacent candidate frequency domain positions are positions corresponding to two GSCNs, and there is an interval of X numbers between the two adjacent candidate frequency domain positions, that is, step size = X, and optionally, as shown in Table 8, starting from the initial position S1, every X GSCNs is a candidate frequency domain position. Optionally, a position corresponding to a GSCN offset by O1 based on a certain reference position is a candidate frequency domain position.

[0290] For another type of synchronization signal or broadcast signal, two adjacent candidate frequency domain positions are positions corresponding to two GSCNs, and there is a gap of Y numbers between the two adjacent candidate frequency domain positions, that is, step size = Y, and optionally, as shown in Table 8, taking band 38 as an example, starting from the initial position S2, every Y GSCN is a candidate frequency domain position. Optionally, a position corresponding to an offset of O2 GSCNs based on a certain reference position is a candidate frequency domain position. Among them, X and Y may be the same or different. O1 and O2 may be the same or different. S1 and S2 may be the same or different. For example, the offset corresponding to the synchronization signal or broadcast signal of RedCap may be different from the offset corresponding to other synchronization signals or broadcast signals, so that the corresponding positions are different. This embodiment is not only applicable to band 38 but to any band.

[0291] Table 7

[0292] Table 8

[0293] In some embodiments, assuming the first object is a synchronization signal or broadcast signal, mapping of the synchronization signal or broadcast signal can be performed based on the protocol's predefined binding relationship between the operating frequency band and the frequency domain resource location, facilitating terminal search during initial access. As shown in Table 6, using band 38 as an example, frequency domain locations where synchronization signals or broadcast signals may be transmitted / received / searched are defined. These locations are part of the ARFCN, but the offset depends on the type of synchronization signal or broadcast signal. This embodiment is applicable not only to band 38 but to any band.

[0294] For a certain synchronization signal or broadcast signal type, two adjacent candidate frequency domain positions correspond to two ARFCN positions, and there is an interval of X numbers between the two adjacent candidate frequency domain positions, that is, step size = X. Optionally, as shown in Table 7, taking band 38 as an example, starting from the initial position S1, every X ARFCNs are considered a candidate frequency domain position. Alternatively, a position corresponding to a reference position offset by O1 ARFCNs is considered a candidate frequency domain position. This embodiment is not limited to band 38 but is applicable to any band.

[0295] For certain other types of synchronization signals or broadcast signals, two adjacent candidate frequency domain positions correspond to two ARFCNs, and there is a Y number interval between the two adjacent candidate frequency domain positions, i.e., step size = Y. Optionally, as shown in Table 8, taking band 38 as an example, starting from the initial position S2, every Y number of ARFCNs is a candidate frequency domain position. Alternatively, a position corresponding to a reference position offset by O2 ARFCNs is a candidate frequency domain position. This embodiment is not limited to band 38 but applies to any band.

[0296] Here, X and Y may be the same or different. O1 and O2 may be the same or different. S1 and S2 may be the same or different. For example, the offset corresponding to the RedCap synchronization signal or broadcast signal may be different from the offset corresponding to other synchronization signals or broadcast signals, resulting in different corresponding positions. For example, S1 corresponding to the RedCap synchronization signal or broadcast signal may be different from S2 corresponding to other synchronization signals or broadcast signals, resulting in different corresponding positions.

[0297] It should be noted that the examples above use GSCN and ARFCN. In practice, other grid systems or scales may be defined, so the step size, offset, and starting position described above may also be defined based on other grid systems or scales. For example, if a scale is defined with a frequency domain position every Z kHz, then step size = X means the actual position is Z * K kHz. And so on.

[0298] For example, the synchronization signals or broadcast signals of full duplex and half duplex use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions, which is beneficial for staggering or avoiding interference.

[0299] For example, the synchronization signals or broadcast signals of artificial intelligence (AI)-based access and fallback-based access use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions. Further, for example, a special search method, such as unequal step sizes, is used for AI-based access.

[0300] For example, the synchronization signals or broadcast signals of the macro and small cells use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0301] For example, the synchronization signal / broadcast signal of the cell / channel / BWP using the OTFS waveform uses different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0302] For example, the long-period and short-period synchronization signals / broadcast channels use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0303] For example, synchronization signals or broadcast signals with different or specific periods or with and without paging / SIB / RACH enabled may use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0304] For example, the synchronization signals or broadcast signals of sensing services, NTN, and LP-SS / WUS use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0305] For example, when special services are enabled or not enabled, synchronization signals or broadcast signals such as data plane, NPN, or simplified protocol stack use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0306] In some embodiments, the first information is located at a specific position, or at least part of the bits of the first information are located at a specific position.

[0307] Specifically, the specific position may be the position or number of the first information in a plurality of information, or the specific position may be the position or number of at least part of the bits of the first information in a string of bits.

[0308] In some embodiments, the specific location satisfies at least one of the following:

[0309] If the first object corresponds to at least two types of first information, the at least two types of first information have respective specific positions, or at least some bits of the first information have respective specific positions;

[0310] If at least two types of objects have respective corresponding first information, the first information corresponding to the at least two types of objects respectively have respective specific locations;

[0311] If the first object corresponds to at least two first information, the specific position is a collection or union of the specific positions corresponding to the at least two first information, or the specific position is a position corresponding to a result of XORing, summing, or adding the specific positions corresponding to the at least two first information;

[0312] If at least two types of objects have respective corresponding first information, the specific position is the set or union of the specific positions of the first information corresponding to the at least two types of objects, or the specific position is the position corresponding to the result of exclusive OR, sum, or AND of the specific positions of the first information corresponding to the at least two types of objects;

[0313] If the first object corresponds to at least two types of first information, the length of the specific position is the maximum number of bits required by the at least two types of first information, or the length of the specific position is the sum or weighted sum of the number of bits required by the at least two types of first information;

[0314] If at least two types of objects have respective corresponding first information, the length of the specific position is the sum or weighted sum of the number of bits required for the respective first information corresponding to the at least two types of objects;

[0315] The length of the specific position is an integer multiple of S bits, where S is a positive integer;

[0316] The at least two types of objects include the first object.

[0317] Optionally, S may be agreed upon by a protocol, or configured by the network side. For example, S=8.

[0318] In some embodiments, at least some of the bits of the first information are generated at a physical layer, or at least some of the bits of the first information are generated at a higher layer.

[0319] In some embodiments, the first information is carried by the first object.

[0320] In some embodiments, different types of objects are independently configured with the first information, or different types of objects independently determine the first information based on their own transmission time windows or transmission time limits, or specific types of objects are configured with the first information. Specifically, the first object is a specific type of object.

[0321] In some embodiments, different types of objects are independently configured with the second information, or different types of objects independently determine the second information based on their own transmission time windows or transmission time limits, or specific types of objects are configured with the second information. Specifically, the first object is an object of a specific type.

In an embodiment of the present application, the mapping method of the reference signal sequence of the first object can be determined based on the first information or the second information, so that the mapping method of the reference signal sequence of different types of objects can be determined. When detecting or receiving an object, the terminal can determine the object type based on the mapping method of the reference signal sequence, and can also determine the characteristics of different types of objects (such as period, bandwidth, search complexity, time-frequency domain resources, carried information, generation method, etc.), thereby reducing the detection complexity of different types of objects.
