[0002] With the evolution of communication technologies, for example, the application scenarios of 6G will be more than those of 4G and 5G, and there will be many types of terminals that need to be supported. In this case, it may be necessary to support multiple types of objects (such as synchronization signals, broadcast signals, etc.). The characteristics of different types of objects (such as period, bandwidth, search complexity, time-frequency domain resources, carried information, generation method, etc.) may vary, and different types of objects may not be limited to the half-frame window. Since the characteristics such as the period and time-frequency domain resources of different types of objects are no longer the same, and different types of objects may not be limited to the half-frame window, the current mapping method of reference signal sequences cannot meet the requirements of different types of objects.

[0062] Among them, the access network device may also be referred to as a Radio Access Network (RAN) device, a radio access network function, or a radio access network unit.

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

[0063] Among them, the core network devices may include but are not limited to at least one of the following: core network nodes, core network functions, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), Network Data Analytics Function (NWDAF), Location Management Function (LMF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0064] For better understanding of the embodiments of this application, the embodiments of this application are described by taking the object as the Synchronization Signal Block (SSB) as an example.

[0065] In order for the terminal to search for a reasonable cell and synchronize with the selected cell, it is usually necessary for the network to broadcast synchronization signals and provide certain primary information about the cell. Specifically, the SSB may be asFigure 2 As 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 (MIB).

[0066] It should be noted that the SSB can also be referred to as the synchronization signal / physical broadcast channel block (SS / PBCH block).

[0067] To facilitate a better understanding of the embodiments of the present application, some processes in the PBCH generation method are described.

[0068] The 5G PBCH contains 32 bits (bit), and the PBCH does not change within every 80 ms.

[0069] 1. The upper layer generates 24 bits included in the PBCH.

[0070] 2. The physical layer generates 8 bits included in the PBCH. The main information included in these 8 bits is related to the combination with the SSB within 80 ms. For example, the 1 - 4 least significant bits (LSB) of the system frame number (SFN), 3 bits of the most significant bit (MSB) of the 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).

[0071] 3. Concatenate the bits generated by the upper layer and the physical layer into a 32 - bit PBCH payload;

[0072] 1) Perform the first - layer scrambling: Do not scramble some bits in the bits generated by the physical layer, that is, do not scramble the 3 MSB SSB index (or the 3 bits corresponding to the low - frequency band), HFI, and the 2 / 3 LSB SFN of the PBCH, but scramble other bit parts of the PBCH payload.

[0073] A. In the first - layer scrambling, the scrambling sequence is related to the Physical Cell Identifier (PCI) and the 2 / 3 LSB SFN carried in the PBCH.

[0074] B. Since the 2 / 3 LSB SFN is not scrambled for the first time, the 2 / 3 LSB SFN can be determined after PBCH decoding, and then the first - layer scrambling code can be determined. It can be directly descrambled without multiple assumptions and attempts, reducing the complexity.

[0075] 2) Generate Cyclical Redundancy Check (CRC) and perform channel coding on the PBCH payload.

[0076] A. The basic idea of the first - layer scrambling is: Do not scramble different bit parts of the content of two SSBs that can be combined, and scramble the same parts of the content of two SSBs that can be combined.

[0077] B. Since the bits with different content are not scrambled for the first time, the user can determine the positions of the unscrambled bits in the encoded bit string before PBCH payload decoding. After receiving SSBs in multiple periods, the user can directly combine the bit parts with the same content of the SSBs, improving the decoding success rate.

[0078] 3) Perform the second - layer scrambling: Scramble the bits after channel coding collectively.

[0079] A. In the second - layer scrambling, the scrambling sequences corresponding to different SSBs are only related to the PCI and the SSB index or HFI carried in the Demodulation Reference Signal (DMRS).

[0080] B. Therefore, when the user performs the second - layer descrambling, the second - layer scrambling code sequence can be directly deduced according to the relevant information obtained during the DMRS and synchronization signal detection process, without multiple assumptions and attempts, reducing the complexity.

[0081] 4. Quadrature Phase Shift Keying (QPSK) modulation, resource mapping, etc.

[0082] Based on the above analysis, it can be seen that the two-layer scrambling design can ensure that the terminal can decode the PBCH within a short time with relatively low complexity.

[0083] To facilitate a better understanding of the embodiments of the present application, the synchronization raster and GSCN are described.

[0084] 5G NR defines a synchronization raster for 0 - 100 GHz, and the number of the synchronization raster is called GSCN. The base station can send SSB (which can also be called Synchronization Signal / Physical Broadcast Channel Block (SS / PBCH block)) on the synchronization raster. The positions and calculations of GSCN in different frequency ranges are shown in Table 1 below.

[0085] For example, when GSCN = 2, it can be deduced that N = 1 and M = 1, so the corresponding frequency domain position is 1250 kHz.

[0086] Table 1

[0087]

[0088] According to the frequency domain planning of NR, for different subcarrier spacings (SCS), the supported channel bandwidths (bands) are defined for different operating frequency bands. Table 2 below is the information related to the channel bandwidth of band n1. For example, for band n1, when the SCS of the transmitted data / control signal is 15 kHz, the minimum channel bandwidth on this band is 5 MHz.

[0089] Table 2

[0090]

[0091] In NR, the ranges and step sizes or intervals of GSCN are defined for different bands. The step size is the difference between the GSCN numbers of two adjacent synchronization rasters belonging to this band. For example, the GSCN range of n41 is 6246 - 6714, and the step size is 3. The GSCN numbers within the range of n41 are 6246, 6249, ……, 6714.

[0092] It should be noted that there may be frequency domain overlap between different bands. For example, for band n38 and band n41, as can be seen from Table 3 below, although there is overlap between these two frequency bands, the step sizes of GSCN are different.

[0093] Table 3

[0094]

[0095] To facilitate a better understanding of the embodiments of the present application, the channel raster is described.

[0096] In NR, the channel raster is defined, and the base station can deploy channels on the channel raster. The channel raster may be 100 kHz, 15 kHz, 30 kHz, 60 kHz, or 120 kHz.

[0097] For example, in Table 4 below, the channel raster on band n1 is 100 kHz. The range of NR-ARFCN numbers corresponding to the uplink frequency domain is 384000 - 396000, and the range of NR-ARFCN numbers corresponding to the downlink frequency domain is 422000 - 434000. An NR-ARFCN number can also be used to indicate a frequency domain position.

[0098] Table 4

[0099]

[0100] It should be noted that there may be frequency domain overlaps between different bands. For example, between band n38 and band n41. As can be seen from Table 5 below, although there is an overlap between these two frequency bands, the step size of the NR-ARFCN is also different.

[0101] Table 5

[0102]

[0103] In the 5G system, the SSB is limited by a half-frame window. Therefore, special designs are also made in the generation and scrambling processes of the HFI. For example, the terminal searches for synchronization signals on the Synchronization raster. For a given SCS, the interval between Synchronization rasters on the same frequency band is fixed.

[0160] In some embodiments, when the mapping manner of the reference signal sequence of the first object is related to the first information, the position of the mapping of the reference signal sequence of the first object may be determined based on the first information.

[0161] In some embodiments, when the mapping manner of the reference signal sequence of the first object is related to the first information, the position of the mapping of the reference signal sequence of the first object is determined based on the first position information;

[0162] Wherein, 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, a first channel grid;

[0163] Wherein, the first position information is related to the first information.

[0164] In this embodiment, the position of the mapping of the reference signal sequence of the first object determined based on the first position information is the actual position where the reference signal sequence of the first object is mapped, thereby reducing interference between the reference signal sequences of different objects.

[0165] Optionally, the first position information is agreed upon by the protocol, or the first position information is configured by the network side.

[0166] 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 the first object is an 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 on different resource elements (REs), so that the reference signal sequences of the two types of objects do not interfere with each other.

[0167] In some embodiments, the first location information is related to the first information and includes:

[0168] The first location information is determined based on the values of at least some bits of the first information; or,

[0169] The first location information is determined based on the values of at least some bits of the first information and the identifier of at least one physical resource. Optionally, each physical resource in the at least one physical resource is one of the following: cell, carrier, BWP, resource pool, frequency band (band), sub-band (subband). Exemplarily, the cell identifier can be PCI.

[0170] In some embodiments, when the first location information is determined based on the values of at least some bits of the first information, the first location information is determined based on the result of the values of at least some bits of the first information mod C;

[0171] where C represents the frequency-domain interval between two adjacent reference signal resources, or C represents the value after adding 1 to the frequency-domain interval between two adjacent reference signal resources, or C represents the interval between two adjacent objects, or C represents the total number of object types, and mod represents the modulo operation;

[0172] where the types of the two objects are the same as the type of the first object.

[0173] For example, when the first location information is determined based on the values of at least some bits of the first information, the first location information = the values of at least some bits of the first information mod C.

[0174] It should be understood that if C = 1, it means that there is actually no modulo operation on C.

[0175] In some embodiments, when the first location information is determined based on the values 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 the result of ((the values of at least some bits of the first information mod C) * D + ID mod D), or the first location information is determined based on the result of (the values of at least some bits of the first information mod C + (ID mod D) * C), or the first location information is determined based on the result of [((the values 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 the result of [(the values of at least some bits of the first information mod C + (ID mod D) * C) mod E];

[0176] Wherein, C represents the frequency-domain interval between two adjacent reference signal resources, or C represents the value after adding 1 to the frequency-domain interval between two adjacent reference signal resources, or C represents the interval between two adjacent objects, or C represents the total number of object types;

[0177] Wherein, D represents the frequency-domain interval between two adjacent reference signal resources, or D represents the value after adding 1 to the frequency-domain interval between two adjacent reference signal resources, or D represents the interval between two adjacent objects, or D represents the total number of object types;

[0178] Wherein, E represents the frequency-domain interval between two adjacent reference signal resources, or E represents the value after adding 1 to the frequency-domain interval between two adjacent reference signal resources, or E represents the interval between two adjacent objects, or E represents the total number of object types;

[0179] 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 the modulo operation.

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

[0181] For another example, when the first location information is determined based on the values of at least some bits of the first information and the identifier of the at least one physical resource, the first location information = the values of at least some bits of the first information mod C + (ID mod D) * C.

[0182] 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) * D + ID mod D] mod E.

[0183] 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)] mod E.

[0184] It should be understood that if C = 1, it means that there is actually no modulo operation on C; if D = 1, it means that there is actually no modulo operation on D; if E = 1, it means that there is actually no modulo operation on E.

[0185] 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 sequences of different types of objects can be distinguished.

[0186] In some embodiments, if the first information is associated with the 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 manner of the reference signal sequences of objects with different configurations can be distinguished.

[0187] 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 the reference signal sequences of different types of objects can be distinguished.

[0188] 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 sequences of objects with different configurations can be distinguished.

[0189] 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 result, or AND result of the information bits respectively associated with the at least two types. In this embodiment, the mapping manner of the reference signal sequences of different types of objects can be distinguished.

[0190] 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 summation 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 manner of the reference signal sequences of objects corresponding to different attributes can be distinguished.

[0191] 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 a specific type of object. For example, for the SSB used for cell search and downlink synchronization, the mapping manner of its corresponding reference signal sequence is related to the first information; for the SSB used for beam management or channel state information acquisition, the mapping manner of its corresponding reference signal sequence is not related to the first information, or, it is not configured with the first information.

[0192] In some embodiments, when the first information is associated with the configuration information of the first object, the first information includes the association relationship between the configuration of the first object and the mapping manner of the reference signal sequence of the first object. In this embodiment, the mapping manner of the reference signal sequences of objects with different configurations can be distinguished.

[0193] Optionally, when the first information includes the association relationship between the configuration of the first object and the mapping manner of the reference signal sequence of the first object, the mapping manner of the reference signal sequence of the first object can be determined based on the configuration of the first object.

[0194] 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 some valid bits of the frame information (such as the System Frame Number (SFN)) associated with the transmission period or TTI of the first object.

[0195] 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 among the 2nd and 3rd least significant bits (LSB) of the SFN.

[0196] 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 among the 2nd LSB of the SFN.

[0197] 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 among the 2nd, 3rd, and 4th LSB of the SFN.

[0198] 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 among the 1st, 2nd, and 3rd LSB of the SFN.

[0199] 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 among the 1st and 2nd LSB of the SFN.

[0200] 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 among the 1st LSB of the SFN.

[0201] In some embodiments, the transmission period or TTI of the first object can be changed, activated, deactivated, or updated.

[0202] Optionally, the change, activation, deactivation, or update of the transmission period / TTI of the first object is due to at least part (on demand) of the first object being (re)configured, activated, deactivated, released, or overwritten.

[0203] Exemplarily, the first object is the SSB. Assume that the SSB transmission period is 10 ms (considering all SSBs, including on demand SSB), the TTI is 80 ms, and the SSBs in all even cycles are on demand SSBs. If the on demand SSB is not activated, the actual SSB transmission period at this time is twice that when the on demand SSB is activated, that is, 20 ms, and this first information is the 2nd and 3rd LSB SFNs. If the on demand SSB is activated, the actual SSB transmission period at this time is 10 ms, and this first information is at least one bit in the 1st and 2nd LSB SFNs.

[0204] Optionally, the change in the transmission period / TTI of the first object is due to the transmission period / TTI being configured or reconfigured. Exemplarily, switch from the default transmission period / TTI of the first object to the transmission period / TTI supported by the actual network, or change the transmission period / TTI of the first object through system messages or Radio Resource Control (RRC) reconfiguration.

[0205] In some embodiments, when this first information is associated with the transmission period or TTI of this first object, this first information satisfies one of the following:

[0206] Associated with the changed transmission period or TTI;

[0207] Associated with the activated transmission period or TTI;

[0208] Associated with the updated transmission period or TTI;

[0209] Associated with the default transmission period or TTI;

[0210] Associated with all configured transmission periods or TTIs;

[0211] Associated with a specific transmission period or TTI among all configured transmission periods or TTIs;

[0212] Associated with the transmission period or TTI with the maximum length among all configured transmission periods or TTIs;

[0213] Associated with the transmission period or TTI with the minimum length among all configured transmission periods or TTIs.

[0214] Optionally, a specific transmission period or TTI can be agreed upon by the protocol, or a specific transmission period or TTI can be configured by the network side, or a specific transmission period or TTI is the transmission period or TTI with the smallest index or number among all the configured transmission periods or TTIs, or a specific transmission period or TTI is the transmission period or TTI with the largest index or number among all the configured transmission periods or TTIs.

[0215] Exemplarily, if the first object is an SSB and the transmission period / TTI can be changed, activated, deactivated, or updated, this first information can be associated with the (certain / largest / smallest / overall) transmission period / TTI corresponding to all the configured SSBs. For example, in the case of on demand SSB, regardless of whether it is activated, the corresponding SSB period still considers all SSBs. In this case, determining the SFN bits is not affected by whether the on demand SSB is activated.

[0216] In some embodiments, when this first information is associated with the transmission period or TTI of this first object, if the information bits (N1 bits) associated with the updated, changed, activated, or deactivated transmission period or TTI are fewer than the information bits (N2 bits) associated with the current transmission period or TTI, or the information bits (N1 bits) associated with the updated, changed, activated, or deactivated transmission period or TTI are a subset of the information bits (N2 bits) associated with the current transmission period or TTI, this first information is one of the following:

[0225] The remaining information bits after intercepting a part of the information bits associated with the updated, changed, activated, or deactivated transmission period or TTI.

[0226] It should be noted that the current transmission period or TTI can be the transmission period or TTI before being updated, changed, activated, or deactivated.

[0227] Exemplarily, the first information is the remaining information bits after intercepting a part of the information bits associated with the current transmission period or TTI. The remaining information bits after intercepting a part are N1 bits. Among them, the intercepted bits are the high-order bits, and the retained bits are the low-order bits.

[0228] Exemplarily, the first information is the remaining information bits after intercepting a part of the information bits associated with the default transmission period or TTI. The remaining information bits after intercepting a part are N1 bits; optionally, the intercepted bits are the high-order bits, and the retained bits are the low-order bits.

[0229] Exemplarily, the first information is the first specific part of the information bits associated with the current transmission period or TTI, where the first specific part is N1 bits; optionally, the first specific part is the low-order bits.

[0230] Exemplarily, the first information is the first specific part of the information bits associated with the default transmission period or TTI, where the first specific part is N1 bits; optionally, the first specific part is the low-order bits.

[0231] Exemplarily, the first information is the information bits obtained after padding at least one bit to the information bits associated with the updated, changed, activated, or deactivated transmission period or TTI. For example, padding 0 or 1 before the information bits associated with the updated, changed, activated, or deactivated transmission period or TTI to obtain N2 bits.

[0232] In some embodiments, when the first information is associated with the transmission period or TTI, if the information bits (N3 bits) associated with the updated, changed, 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, changed, activated, or deactivated transmission period or TTI, the first information is one of the following:

[0233] Information bits associated with the current transmission period or TTI;

[0234] Information bits associated with the updated, changed, activated, or deactivated transmission period or TTI;

[0235] Default information bits associated with the transmission period or TTI;

[0236] The remaining information bits after intercepting a part of the information bits associated with the updated, changed, activated, or deactivated transmission period or TTI;

[0239] The second specific part of the default information bits associated with the transmission period or TTI;

[0241] The information bits obtained after padding at least one bit to the information bits associated with the current transmission period or TTI;

[0242] The remaining information bits after intercepting a part of the information bits associated with the current transmission period or TTI.

[0243] Exemplarily, the first information is the remaining information bits after intercepting a part of the information bits associated with the updated, changed, activated, or deactivated transmission period or TTI. The remaining information bits after intercepting a part are N4 bits, where the intercepted bits are the high-order bits and the remaining bits are the low-order bits.

[0244] Exemplarily, the first information is the remaining information bits after intercepting a part of the default information bits associated with the transmission period or TTI. The remaining information bits after intercepting a part are N4 bits; optionally, the intercepted bits are the high-order bits and the remaining bits are the low-order bits.

[0245] Exemplarily, the first information is the second specific part of the information bits associated with the updated, changed, activated, or deactivated transmission period or TTI of the first object, where the second specific part is N4 bits; optionally, the second specific part is the low-order bits.

[0246] Exemplarily, the first information is the second specific part of the information bits associated with the default transmission period or TTI, where the second specific part is N4 bits; optionally, the second specific part is the low-order bits.

[0247] Exemplarily, the first information is the information bits obtained after padding at least one bit to the information bits associated with the default transmission period or TTI. For example, 0 or 1 is padded before the information bits associated with the default transmission period or TTI to obtain N3 bits.

[0248] Exemplarily, the first information is the information bits obtained after padding at least one bit to the information bits associated with the current transmission period or TTI. For example, 0 or 1 is padded before the information bits associated with the current transmission period or TTI to obtain N3 bits.

[0249] 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 summation result or AND result of the information bits respectively associated with the at least two transmission periods or TTIs.

[0250] Exemplarily, the first object supports two transmission periods or TTIs, where the transmission period of the first object is 20 ms or the TTI is 160 ms, and the transmission period is 10 ms or the TTI is 40 ms. The first information is at least one bit in the 1st, 2nd, 3rd, and 4th LSB SFN.

[0251] In some embodiments, different types of objects can independently determine the first information according to their own transmission time windows or transmission time limits.

[0252] For example, if the transmission period or TTI of the first object is 5 ms, the first information is 1-bit HFI.

[0253] 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 within a frame.

[0254] In some embodiments, when the first information is associated with the transmission time window or transmission time limit of the first object, the first information satisfies one of the following:

[0255] Associated with the changed transmission time window or transmission time limit;

[0256] Associated with the activated transmission time window or transmission time limit;

[0257] Associated with the updated transmission time window or transmission time limit;

[0258] associated with a default transmission time window or transmission time limit;

[0259] associated with an initial transmission time window or transmission time limit;

[0260] associated with a current transmission time window or transmission time limit.

[0261] In some embodiments, if the transmission time window or transmission time limit of the first object is X, and 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), where 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).

[0262] 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, union, exclusive OR result, summation 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.

[0263] 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 5 ms and the second type of transmission time window or transmission time limit is 2 ms, then the number of bits of the first information is max(1, 4) = 4 bit.

[0264] 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, union, exclusive OR result, summation 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.

[0265] For example, the first object is an SSB, which can support two types of indexes, type A and type B. Type A supports a maximum of 8 SSBs and the index information requires 3 bits. Type B supports a maximum of 16 SSBs and the index requires 4 bits. Then the mapping method of the reference signal sequence corresponding to type A is related to at least some of 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 4-bit index.

[0266] 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, union, exclusive OR result, summation 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.

[0267] 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.

[0268] For example, if the first object is an SSB and supports two types of indexes, type A and type B, type A supports a maximum of 8 SSBs and the index information requires 3 bits, and type B supports a maximum of 16 SSBs and the index requires 4 bits, then the mapping method of the reference signal sequence corresponding to type A / B is related to at least some of the bits in the 4-bit index.

[0269] In some embodiments, when the mapping method of the reference signal sequence of the first object is related to the second information, the position of the mapping of the reference signal sequence of the first object can be determined based on the second information.

[0270] In some embodiments, when the mapping method of the reference signal sequence of the first object is related to the second information, the position of the mapping of the reference signal sequence of the first object is determined based on the second position information;

[0271] Wherein, 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;

[0272] Wherein, the second position information is related to the second information.

[0273] Optionally, the second position information is agreed upon by the protocol or configured by the network side.

[0274] Exemplarily, for a case where a cell supports multiple frequency bands (bands), the mapping of the reference signal sequence of the first object on each band can be different. For example, a time / frequency domain offset (shift) associated with the band is introduced. In this way, the mapping of the reference signal sequence of the first object in a multi-band cell uses a set of shifts. Further, for different cells including multiple bands, different sets of shifts can be used. The set of shifts can depend on the PCI, for example, to reduce interference between the reference signal sequences of such cells.

[0275] 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 positions allowed for mapping of the first object, and the channel grid corresponding to the candidate frequency-domain positions allowed for mapping of the first object.

[0276] 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 positions allowed for mapping of the first object, and the channel grid corresponding to the candidate frequency-domain positions allowed for mapping of the first object, so that the mapping method of the reference signal sequence of the first object can be accurately determined.

[0277] 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 positions allowed for mapping of the first object, and the channel grid corresponding to the candidate frequency-domain positions allowed for mapping of the first object.

[0278] 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 positions allowed for mapping of the first object, and the channel grid corresponding to the candidate frequency-domain positions allowed for mapping of the first object can be determined based on the type of the first object, so that the mapping method of the reference signal sequence of the first object can be further determined.

[0279] 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, at least one of the candidate frequency-domain positions 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 positions allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency-domain positions allowed to be mapped by the first object can be determined based on the configuration information of the first object, so that the mapping method of the reference signal sequence of the first object can be further determined.

[0280] 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, at least one of the candidate frequency-domain positions 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 positions allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency-domain positions allowed to be mapped by the first object can be determined based on the transmission period or TTI of the first object, so that the mapping method of the reference signal sequence of the first object can be further determined.

[0281] 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, at least one of the candidate frequency-domain positions 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 positions allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency-domain positions 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, so that, the mapping method of the reference signal sequence of the first object can be further determined.

[0282] 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 positions 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 positions allowed to be mapped by the first object, and the channel grid corresponding to the candidate frequency-domain positions allowed to be mapped by the first object can be determined based on the index or number of the first object, so that, the mapping method of the reference signal sequence of the first object can be further determined.

[0283] In some embodiments, the second information is associated with at least one of the following:

[0284] 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.

[0285] Exemplarily, if the second information includes the frequency band corresponding to 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 frequency band corresponding to the type of the first object. Thus, the mapping manner of the reference signal sequence of the first object can be further determined.

[0286] Exemplarily, if the second information includes the frequency band range corresponding to 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 frequency band range corresponding to the type of the first object. Thus, the mapping manner of the reference signal sequence of the first object can be further determined.

[0287] Exemplarily, if the second information includes the resource type corresponding to 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 resource type corresponding to the type of the first object. Thus, the mapping manner of the reference signal sequence of the first object can be further determined.

[0288] In some embodiments, assuming that the first object is a synchronization signal or a broadcast signal, the mapping of the synchronization signal or the broadcast signal can be performed based on the binding relationship between the working frequency band predefined by the protocol and the frequency-domain resource position, which is beneficial for the terminal to search during initial access. As shown in Table 6, taking band 38 as an example, the frequency-domain positions where the synchronization signal or the broadcast signal may be used for transmission / reception / search are defined. These positions are part of the GSCN, but the adjustment step size is related to the type of the synchronization signal or the broadcast signal. For a certain type of synchronization signal or broadcast signal, the two adjacent candidate frequency-domain positions are the positions corresponding to two GSCNs, and there are X numbers between the two GSCNs, that is, step size = X; for another type of synchronization signal or broadcast signal, the two adjacent candidate frequency-domain positions are the positions corresponding to two GSCNs, and there are Y numbers between the two GSCNs, that is, step size = Y. For example, the step size corresponding to the synchronization signal or the broadcast signal of RedCap may be relatively large, thus effectively reducing the search complexity. This embodiment is not only applicable to band 38 but also applicable to any band.

[0289] Table 6

[0290]

[0291] In some embodiments, assuming that the first object is a synchronization signal or a broadcast signal, the frequency-domain positions where the synchronization signal or the 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 the broadcast signal. For a certain type of synchronization signal or broadcast signal, the two adjacent candidate frequency-domain positions are the positions corresponding to two ARFCNs, and there are X numbers between the two ARFCNs, that is, step size = X; for another type of synchronization signal or broadcast signal, the two adjacent candidate frequency-domain positions are the positions corresponding to two ARFCNs, and there are Y numbers between the two ARFCNs, that is, step size = Y. For example, the step size corresponding to the synchronization signal or the broadcast signal of RedCap may be relatively large, thus effectively reducing the search complexity.

[0292] In some embodiments, assuming that the first object is a synchronization signal or a broadcast signal, the mapping of the synchronization signal or the broadcast signal can be performed based on the binding relationship between the working frequency band predefined by the protocol and the frequency domain resource position, which is beneficial for the terminal to search during initial access. As shown in Table 7, taking band 38 as an example, the frequency domain positions where the synchronization signal or the broadcast signal may be used for transmission / reception / search are defined. These positions are part of the GSCN. However, the offset is related to the type of the synchronization signal or the broadcast signal. This embodiment is not only applicable to band 38 but to any band.

[0293] For a certain type of synchronization signal or broadcast signal, two adjacent candidate frequency domain positions are the positions corresponding to two GSCNs, and there are X numbers between the two adjacent candidate frequency domain positions, that is, step size = X. Optionally, as shown in Table 8, starting from the initial position S1, every X GSCNs is a candidate frequency domain position. Optionally, the position corresponding to O1 GSCNs offset from a certain reference position is a candidate frequency domain position.

[0294] For another type of synchronization signal or broadcast signal, two adjacent candidate frequency domain positions are the positions corresponding to two GSCNs, and there are Y numbers between the two adjacent candidate frequency domain positions, that is, step size = Y. Optionally, taking band 38 as an example, as shown in Table 8, starting from the initial position S2, every Y GSCNs is a candidate frequency domain position. Optionally, the position corresponding to O2 GSCNs offset from 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 the broadcast signal of RedCap may be different from the offset corresponding to other synchronization signals or broadcast signals, so the corresponding positions are different. This embodiment is not only applicable to band 38 but to any band.

[0297] Table 8

[0298]

[0299] In some embodiments, assuming that the first object is a synchronization signal or a broadcast signal, the mapping of the synchronization signal or the broadcast signal can be performed based on the binding relationship between the working frequency band predefined by the protocol and the frequency-domain resource position, which is beneficial for the terminal to search during initial access. As shown in Table 6, taking band 38 as an example, the frequency-domain positions where the synchronization signal or the broadcast signal may be used for transmission / reception / search are defined. These positions are part of the ARFCN, but the offset is related to the type of the synchronization signal or the broadcast signal. This embodiment is not only applicable to band 38 but to any band.

[0300] For a certain type of synchronization signal or broadcast signal, the two adjacent candidate frequency-domain positions are the positions corresponding to two ARFCNs, and there are X numbers between the two adjacent candidate frequency-domain positions, that is, step size = X. And optionally, as shown in Table 7, taking band 38 as an example, starting from the initial position S1, every X ARFCNs is a candidate frequency-domain position. Or, the position corresponding to an offset of O1 ARFCNs based on a certain reference position is a candidate frequency-domain position. This embodiment is not only applicable to band 38 but to any band.

[0301] For another certain type of synchronization signal or broadcast signal, the two adjacent candidate frequency-domain positions are the positions corresponding to two ARFCNs, and there are 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 ARFCNs is a candidate frequency-domain position. Or, the position corresponding to an offset of O2 ARFCNs based on a certain reference position is a candidate frequency-domain position. This embodiment is not only applicable to band 38 but to any band.

[0302] 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 the broadcast signal of RedCap may be different from the offset corresponding to other synchronization signals or broadcast signals, so the corresponding positions are different. For example, S1 corresponding to the synchronization signal or the broadcast signal of RedCap may be different from S2 corresponding to other synchronization signals or broadcast signals, so the corresponding positions are different.

[0303] It should be noted that in the above examples, GSCN and ARFCN are used for illustration. In fact, other raster systems or scales may also be defined. Therefore, the above step size, offset, and starting position may also be defined by other raster systems or scales. For example, a scale is defined where there is a frequency domain position every Z kHz, and step size = X actually means Z*K kHz. And so on.

[0304] 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 (step size) or offsets (offset) or starting positions, which is beneficial to stagger or avoid interference.

[0305] For example, the synchronization signals or broadcast signals of AI (Artificial Intelligence)-based access and fallback-based access use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes (step size) or offsets (offset) or starting positions. Further, for example, a special search method, such as non-uniform step size, is used for AI-based access.

[0306] For example, the synchronization signals or broadcast signals of macro and small cell use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes (step size) or offsets (offset) or starting positions.

[0307] For example, the synchronization signals / broadcast signals of cells / channels / BWPs using OTFS waveforms use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes (step size) or offsets (offset) or starting positions.

[0308] For example, the synchronization signals / broadcast channels of long periods and short periods use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes (step size) or offsets (offset) or starting positions.

[0309] For example, the synchronization signals or broadcast signals with different or specific periods or with paging / SIB / RACH enabled and disabled use different or specific reference positions or synchronization grids or channel grids or adjustment step sizes (step size) or offsets (offset) or starting positions.

[0310] For example, for the sensing service, NTN, the synchronization signal or broadcast signal of LP-SS / WUS uses different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0311] For example, when a special service is enabled or not, such as the synchronization signal or broadcast signal of the data plane, NPN, or simplified protocol stack, etc., uses different or specific reference positions or synchronization grids or channel grids or adjustment step sizes or offsets or starting positions.

[0312] In some embodiments, the position of the first information is at a specific position, or at least some bits of the first information are at specific positions.

[0313] Specifically, the specific position may be the position or number of the first information among multiple information, or the specific position may be the position or number of at least some bits of the first information in a string of bits.

[0314] In some embodiments, the specific position satisfies at least one of the following:

[0315] If the first object corresponds to at least two types of first information, the at least two types of first information have their respective specific positions, or at least some bits of the first information have their respective specific positions;

[0316] If at least two types of objects have their respective corresponding first information, the first information corresponding to each of the at least two types of objects has its own specific position;

[0317] If the first object corresponds to at least two types of first information, the specific position is the union or intersection of the specific positions corresponding to the at least two types of first information, or the specific position is the position corresponding to the result of performing an OR, XOR, sum, or AND operation on the specific positions corresponding to the at least two types of first information;

[0318] If at least two types of objects have their respective corresponding first information, the specific position is the union or intersection of the specific positions of the first information corresponding to each of the at least two types of objects, or the specific position is the position corresponding to the result of performing an OR, XOR, sum, or AND operation on the specific positions of the first information corresponding to each of the at least two types of objects;

[0319] If the first object corresponds to at least two types of first information, the length of the specific position is the maximum value of the number of bits required for 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 for the at least two types of first information;

[0320] If at least two types of objects have their respective corresponding first information, the length of the specific position is the sum or weighted sum of the number of bits required for the first information corresponding to each of the at least two types of objects;

[0321] The length of the specific position is an integer multiple of S bits, where S is a positive integer;

[0322] Wherein, the at least two types of objects include the first object.

[0323] Optionally, S can be agreed upon by the protocol, or S is configured by the network side. For example, S = 8.

[0324] In some embodiments, at least some bits of the first information are generated at the physical layer, or at least some bits of the first information are generated at the high layer.

[0325] In some embodiments, the first information is carried by the first object.

[0326] 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 window or transmission time limit, or a specific type of object is configured with the first information. Specifically, the first object is a specific type of object.

[0327] 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 window or transmission time limit, or a specific type of object is configured with the second information. Specifically, the first object is a specific type of object.

In the embodiments of the present application, the mapping manner 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 manners of the reference signal sequences 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 manner 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.
