[0172] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of this application.

[0173] As shown in Figure 1A, the communication system 100 includes a terminal 101 and a network device 102.

[0174] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things (IoT) device, narrowband Internet of Things (NB-IoT) device, satellite communication device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, and red-capped terminal, but is not limited thereto.

The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in the embodiments of this application are also applicable to similar technical problems.

Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G / 6G).

[0181] In some embodiments, the terminal can use the cell synchronization signal to synchronize downlink time and frequency and obtain the Physical Cell Identity (PCID). In New Radio (NR), the Synchronization Signal Block (SSB) includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH).

[0182] In some embodiments, the structure of an SSB can be as shown in Figure 1B. An SSB consists of three parts: PSS, SSS, and PBCH, where the PBCH contains the demodulation reference signal (DM-RS). An SSB has the following characteristics in the time-frequency domain:

[0183] In the time domain: the time domain occupies 4 consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols. PSS is in OFDM symbol #0, SSS is in OFDM symbol #2, and PBCH is in OFDM symbols #1, #2, and #3. PBCH contains DM-RS.

[0184] In the frequency domain: an SSB occupies 20 consecutive Physical Resource Blocks (PRBs) in the frequency domain.

[0185] In this system, the PSS and SSS are mapped onto 127 Resource Elements (REs) in the center of PRBs #4 to #15 (a total of 12 PRBs) within their respective OFDM symbols. The 17 REs in these 12 PRBs that are not mapped to PSS or SSS are all mapped to 0. The mappings of PBCH and DM-RS in OFDM symbols #1 and #3 respectively occupy all 240 REs of 20 PRBs, and the mapping in OFDM symbol #2 occupies all 96 REs of the first and last 8 PRBs. Therefore, the total number of REs occupied by the PBCH mapping in an SSB is 576. The center frequencies of PSS / SSS and PBCH are aligned, and they all use the same subcarrier spacing.

[0186] In some embodiments, the synchronization signal of the NR SSB includes a primary synchronization signal PSS and a secondary synchronization signal SSS. The PSS has three sequences, corresponding to three IDs. One PSS corresponds to 336 SSS sequences, and the ID of the SSS is... NR supports a total of 1008 cell identifiers (PCIDs). The ID of each cell is determined by a combination of the PSS sequence and the SSS sequence.

[0187] In some embodiments, the synchronization signal of the NR SSB includes a primary synchronization signal PSS and a secondary synchronization signal SSS. The PSS has three sequences, corresponding to three IDs. One PSS corresponds to 336 SSS sequences, and the ID of the SSS is... NR supports a total of 1008 cell identifiers (PCIDs). The ID of each cell is determined by a combination of the PSS sequence and the SSS sequence.

[0188] In some embodiments, the NR PSS sequence is obtained by modulating a 127-length m-sequence with binary phase shift keying (BPSK), and the three PSS sequences are obtained by different cyclic shifts.

[0189] Alternatively, the PSS sequence can be obtained by the following formula: d PSS (n) = 1 - 2x(m). Where, 0 ≤ n < 127.

[0190] Based on the above formula, the cyclic shift positions corresponding to the three PSS sequences are 0, 43, and 86, respectively. The intervals between these three cyclic shifts are relatively large, thus allowing for better differentiation of different PSSs. Since searching for a PSS is the first signal the UE uses in cell search and has no prior information, the number of PSSs is small.

[0191] In some embodiments, the NR SSS sequence is obtained by BPSK modulation of a 127-length Gold sequence, and 336 SSS sequences are obtained by different cyclic shifts.

[0192] Understandably, Gold sequences possess excellent autocorrelation and cross-correlation properties, with the cross-correlation properties being similar to those of m sequences, but their autocorrelation properties are not as good. When using generator polynomials of the same order, the number of Gold sequences generated far exceeds the number of m sequences; therefore, Gold sequences can be used in SSS (Sequential Summarization and Execution System).

[0193] Optionally, the cyclic shift of the SSS sequence and and The correlation can be obtained using the following formula:

[0194] d SSS (n) = [1 - 2x0((n + m0) mod 127)][1 - 2x1((n + m1) mod 127)], where,

[0195] Based on the above formula, it can be seen that SSS is generated by the cascading of two generator polynomials. Regardless of and As for the value, m0 can only take 9 values: {0, 5, 10, 15, 20, 25, 30, 35, 40}.

[0196] In some embodiments, the SSB is transmitted as a whole each time it is sent. A transmission cycle contains one SSB burst set. Depending on the frequency band deployment and the corresponding sub-carrier spacing (SCS), the number of SSBs in a burst set can be 4, 8, or 64. In actual network deployments, the PSS / SSS is mainly used by the UE to complete time-frequency synchronization, obtain the cell's PCID, and complete some measurements, while the PBCH contains the Master Information Block (MIB) and the physical timing information of the SSB burst sets.

[0197] SSB burst sets are a method of transmitting SSBs using beamforming and beam scanning technologies. A group of multiple SSBs transmitted by a cell in one beam scan (i.e., one round-robin) is called an SSB burst set. SSB burst sets are transmitted periodically. SSB beam scanning and SSB burst sets can be illustrated in Figure 1C.

[0198] In some embodiments, after initial access is completed, the UE only needs to periodically receive PSS / SSS to ensure its time and frequency accuracy and perform simple measurement operations, without the need for network access. Therefore, the UE does not need to frequently receive / decode PBCH. If the SSB sends PSS / SSS and PBCH as a whole each time, it will consume more resources and waste resources and energy.

[0199] Therefore, in some embodiments, the synchronization signals PSS / SSS and PBCH can be semi-decoupled. That is, the PSS / SSS is mapped and transmitted independently, without needing to include the PBCH in the mapping and transmission; this is called a light function SSB. When the PBCH is mapped and transmitted, an associated PSS / SSS must be transmitted, and the UE needs to receive / decode both the PSS / SSS and the PBCH; this is called a full function SSB. In this case, the periods of both the full function SSB and the light function SSB can be extended accordingly, thereby saving resources and energy. However, when both the full function SSB and the light function SSB are transmitted in the same cell, it is necessary to consider how to distinguish between them so that the UE can perform subsequent corresponding steps after detection. For example, for an initial access UE, upon detecting a light function SSB, PBCH decoding may not be required.

[0200] As an example, the transmission of a lightweight SSB that is semi-decoupled from PSS / SSS and PBCH can be shown in Figure 1D. The transmission period of PSS / SSS is T1 (=640ms) and the transmission period of PBCH is T2 (=1280ms).

[0205] In some embodiments, terminal 101 receives at least one of a first information block and a second information block sent by network device 102.

[0206] In some embodiments, the first information block includes a first synchronization signal and a first physical broadcast channel (PBCH), and the second information block includes at least one of a second synchronization signal and a second PBCH.

[0207] Furthermore, the pattern of the first information block is different from the pattern of the second information block.

[0208] In some embodiments, the difference between the pattern of the first information block and the pattern of the second information block may refer to a difference in the structure within the first information block and the structure within the second information block. That is, the content included in the first information block and the second information block may differ, or the relative positions of the content within the first information block and the second information block may differ. For example, the second information block may only include the PBCH, or the second information block may only include the synchronization signal, or it may include both the PBCH and the synchronization signal, but with a structure different from the first information block. The following embodiments provide a more detailed description of the pattern differences.

[0209] In some embodiments, the first information block may include a first synchronization signal and a first PBCH.

[0210] Optionally, the first synchronization signal mentioned above includes at least one of PSS and SSS.

[0215] Optionally, the aforementioned first system information may include the most important basic information on the network side, or the aforementioned first system information may include some or all of the system information necessary for terminal 101 to access the network.

[0216] In some embodiments, the first information block is sent based on a first cycle.

[0217] Optionally, the value of the first period is a non-negative integer, and the value of the first period includes, but is not limited to, {5, 10, 20, 40, 80, 160, 320, 640, 1280}, and the unit can be milliseconds.

[0218] Alternatively, the unit of the first period mentioned above can also be other time units, which are not limited here.

[0219] In some embodiments, the name of the first information block is not limited, and may be, for example, "information block", "synchronization signal block", "synchronization signal and broadcast channel block", "full-function information block", "full-quantity information block", "full-function synchronization signal block", "full-function synchronization signal and broadcast channel block", etc.

[0220] In some embodiments, the second information block may include at least one of a second synchronization signal and a second PBCH.

[0221] In some embodiments, the second information block may include only the second PBCH, or only the second synchronization signal, or both the second PBCH and the second synchronization signal.

[0222] Optionally, the aforementioned second synchronization signal includes at least one of PSS and SSS.

[0223] Optionally, the aforementioned second synchronization signal may include only one or more PSSs, or only one or more SSSs, or at least one PSS and at least one SSS (e.g., one PSS and one SSS, or one PSS and multiple SSSs, or multiple PSSs and one SSS, or multiple PSSs and multiple SSSs, etc.).

[0224] Optionally, the second synchronization signal includes at least one signal generated based on a reference sequence (sequence length N, N>0), each signal being obtained by modulating and cyclically shifting the reference sequence.

[0225] Optionally, the reference sequence can be a ZC sequence, an m sequence, a Gold sequence, etc.

[0226] Optionally, the second PBCH carries second system information.

[0227] Optionally, the aforementioned second system information may be simplified system information, may be the main information block (MIB), may be part of the information in the MIB, or may be other system information, etc.

[0228] Optionally, the aforementioned second system information may also include other information related to the transmission time of the aforementioned second information block, etc.

[0229] Optionally, the aforementioned second system information may include some network-side information required by the terminal, etc. Alternatively, the aforementioned second system information may include some or all of the system information necessary for the terminal 101 to access the network, etc.

[0230] In some embodiments, the payload of the second system information may be less than or equal to the first system information.

[0231] In some embodiments, the second information block is sent based on a second cycle.

[0232] Optionally, the second cycle described above may be the same as or different from the first cycle described above.

[0233] Optionally, the value of the second period is a non-negative integer, and the value of the second period includes, but is not limited to, {5, 10, 20, 40, 80, 160, 320, 640, 1280}, and the unit can be milliseconds.

[0234] Alternatively, the unit of the second period mentioned above can also be other time units, which are not limited here.

[0235] In some embodiments, the name of the second information block is not limited, and may be, for example, "information block", "synchronization signal block", "synchronization signal and broadcast channel block", "lightweight function information block", "lightweight information block", "lightweight function synchronization signal block", "lightweight function synchronization signal and broadcast channel block", etc.

[0236] In some embodiments, the pattern of the first information block differs from the pattern of the second information block, including at least one of the following:

[0237] The amount of time-frequency domain resources occupied by the second PBCH is different from the amount of time-frequency domain resources occupied by the first PBCH.

[0238] The time-frequency domain resources occupied by the second PBCH are located in the second information block at a different position than the time-frequency domain resources occupied by the first PBCH are located in the first information block.

[0239] In some embodiments, the amount of time-frequency domain resources occupied by the second PBCH is different from the amount of time-frequency domain resources occupied by the first PBCH, including at least one of the following:

[0240] The amount of time-domain resources occupied by the second PBCH is different from the amount of time-domain resources occupied by the first PBCH.

[0241] The amount of frequency domain resources occupied by the second PBCH is different from the amount of frequency domain resources occupied by the first PBCH.

[0242] Optionally, the time-domain resources occupied by the second PBCH can be a subset of the time-domain resources occupied by the first PBCH, so that the number of time-domain resources occupied by the second PBCH can be less than the number of time-domain resources occupied by the first PBCH.

[0243] Optionally, the first PBCH carries first system information, and the second PBCH carries second system information. The second system information can be simplified system information compared to the first system information, so that the number of frequency domain resources occupied by the second PBCH can be less than the number of frequency domain resources occupied by the first PBCH.

[0244] In some embodiments, the position of the time-frequency domain resources occupied by the second PBCH in the second information block is different from the position of the time-frequency domain resources occupied by the first PBCH in the first information block, including at least one of the following:

[0245] The position of the temporal resources occupied by the second PBCH in the second information block is different from the position of the temporal resources occupied by the first PBCH in the first information block.

[0246] The position of the frequency domain resources occupied by the second PBCH in the second information block is different from the position of the frequency domain resources occupied by the first PBCH in the first information block.

[0247] Optionally, the position of the time-domain resources occupied by the second PBCH in the second information block can be a subset of the position of the time-domain resources occupied by the first PBCH in the first information block. For example, if the first PBCH occupies the first, second, and third time-domain symbols in the first information block, the second PBCH can occupy only one or any two of the first, second, and third time-domain symbols in the second information block.

[0248] Optionally, the position of the frequency domain resources occupied by the second PBCH in the second information block can be a subset of the position of the frequency domain resources occupied by the first PBCH in the first information block.

[0249] It should be noted that when the first information block and the second information block are rate matched, the same time-frequency domain resources are used for rate matching. Therefore, because the amount of time-frequency domain resources occupied by the second PBCH is different from the amount occupied by the first PBCH, and / or the position of the time-frequency domain resources occupied by the second PBCH in the second information block is different from the position of the time-frequency domain resources occupied by the first PBCH in the first information block, the waveform of the second information block is different from the waveform of the first information block. This difference in waveform allows the terminal 101 to distinguish between the two information blocks.

[0250] In some embodiments, the amount of time-frequency domain resources occupied by the second PBCH is different from the amount of time-frequency domain resources occupied by the first PBCH, including at least one of the following:

[0251] The number of time-domain symbols occupied by the second PBCH is different from the number of time-domain symbols occupied by the first PBCH.

[0252] The frequency domain resource length occupied by the second PBCH on the i-th time domain symbol in the second information block is different from the frequency domain resource length occupied by the first PBCH on the i-th time domain symbol in the first information block, where i is a non-negative integer less than m, and m is the smaller value between the number of time domain symbols contained in the second information block and the number of time domain symbols contained in the first information block.

[0253] Optionally, the time-domain symbols occupied by the second PBCH can be a subset of the time-domain symbols occupied by the first PBCH, so that the number of time-domain symbols occupied by the second PBCH can be less than the number of time-domain symbols occupied by the first PBCH.

[0254] Optionally, the length of the frequency domain resources occupied by the second PBCH on the i-th time domain symbol in the second information block may be less than the length of the frequency domain resources occupied by the first PBCH on the i-th time domain symbol in the first information block, wherein i is a non-negative integer less than m, and m is the smaller value between the number of time domain symbols contained in the second information block and the number of time domain symbols contained in the first information block.

[0255] In some embodiments, the position of the time-frequency domain resources occupied by the second PBCH in the second information block is different from the position of the time-frequency domain resources occupied by the first PBCH in the first information block, including at least one of the following:

[0256] The position of the frequency domain resources occupied by the second PBCH on the i-th time-domain symbol in the second information block is different from the position of the frequency domain resources occupied by the first PBCH on the i-th time-domain symbol in the first information block. The position includes at least one of the start position and the end position, where i is a non-negative integer less than m, and m is the smaller value between the number of time-domain symbols contained in the second information block and the number of time-domain symbols contained in the first information block.

[0257] The position of the time-domain symbol occupied by the second PBCH in the second information block is a subset of the position of the time-domain symbol occupied by the first PBCH in the first information block.

[0258] It is understood that if the length of the frequency domain resources occupied by the second PBCH on the i-th time-domain symbol in the second information block is different from the length of the frequency domain resources occupied by the first PBCH on the i-th time-domain symbol in the first information block, then the starting position of the frequency domain resources occupied by the second PBCH on the i-th time-domain symbol in the second information block is different from the starting position of the frequency domain resources occupied by the first PBCH on the i-th time-domain symbol in the first information block, and / or, the ending position of the frequency domain resources occupied by the second PBCH on the i-th time-domain symbol in the second information block is different from the ending position of the frequency domain resources occupied by the first PBCH on the i-th time-domain symbol in the first information block.

[0259] In some embodiments, the second PBCH occupies multiple time-domain symbols, and the second PBCH satisfies at least one of the following:

[0260] :

[0261] For each time-domain symbol, the frequency-domain resources occupied by the second PBCH have the same start and end positions in the second information block.

[0262] In at least one of the aforementioned time-domain symbols, the position of the frequency domain resources occupied by the second PBCH in the second information block is different from the position of the frequency domain resources occupied by the second PBCH in the second information block on other time-domain symbols, and the aforementioned position includes at least one of the start position and the end position;

[0263] The frequency domain resources occupied by the second PBCH on each time domain symbol are symmetrical based on the center frequency, which is the middle position of the frequency domain resources occupied by the second information block.

[0264] Optionally, the frequency domain resources occupied by the second PBCH on each time domain symbol have the same start and end positions in the second information block. The start position of the frequency domain resources occupied by the second PBCH on the j-th time domain symbol in the second information block can be the position of the lowest subcarrier in the frequency domain resources occupied by the second PBCH on the j-th time domain symbol, and the end position of the frequency domain resources occupied by the second PBCH on the j-th time domain symbol in the second information block can be the position of the highest subcarrier in the frequency domain resources occupied by the second PBCH on the j-th time domain symbol, where j is a non-negative integer less than n, and n is the number of time domain symbols contained in the second information block.

[0265] Optionally, the starting position of the frequency domain resources occupied by the second PBCH on the j-th time-domain symbol in the second information block is different from the starting position of the frequency domain resources occupied by the second PBCH on other time-domain symbols in the second information block, and / or, the ending position of the frequency domain resources occupied by the second PBCH on the j-th time-domain symbol in the second information block is different from the ending position of the frequency domain resources occupied by the second PBCH on other time-domain symbols in the second information block, wherein j is a non-negative integer less than n, n is the number of time-domain symbols contained in the second information block, n is greater than or equal to 2, and other time-domain symbols are at least one time-domain symbol other than the j-th time-domain symbol among the time-domain symbols contained in the second information block.

[0266] Optionally, the number of PRBs occupied by the second PBCH on each time-domain symbol is symmetrical about the center frequency, which is the middle position of the PRBs occupied by the second information block.

Specifically, Figure 2B a) is a schematic diagram of the structure of a first information block provided in an embodiment of this application, Figure 2B b) is a schematic diagram of the structure of a second information block provided in an embodiment of this application, and Figure 2B c) is a schematic diagram of the structure of another second information block provided in an embodiment of this application.

[0268] The structure of the first information block shown in Figure 2B a) is the same as that of the SSB in Figure 1B, and will not be described again here.

[0270] In this context, the starting position of the frequency domain resources occupied by the second PBCH on the j-th time domain symbol in the second information block is the position of the lowest subcarrier in the frequency domain resources occupied by the second PBCH on the j-th time domain symbol, and the ending position of the frequency domain resources occupied by the second PBCH on the j-th time domain symbol in the second information block is the position of the highest subcarrier in the frequency domain resources occupied by the second PBCH on the j-th time domain symbol. Here, j is a non-negative integer less than n, and n is the number of time domain symbols contained in the second information block. In Figure 2B, n = 4.

[0271] In Figure 2B, the pattern of the second information block shown in Figure 2B b) differs from the pattern of the first information block shown in Figure 2B a), including:

[0272] The amount of frequency domain resources occupied by the second PBCH is different from the amount of frequency domain resources occupied by the first PBCH;

[0273] The frequency domain resources occupied by the second PBCH are located in the second information block in a different position than the frequency domain resources occupied by the first PBCH in the first information block.

[0274] The amount of frequency domain resources occupied by the second PBCH differs from that occupied by the first PBCH, including:

[0275] The frequency domain resource length occupied by the second PBCH on the first time domain symbol in the second information block is less than the frequency domain resource length occupied by the first PBCH on the first time domain symbol in the first information block.

[0276] The frequency domain resource length occupied by the second PBCH on the second time domain symbol in the second information block is less than the frequency domain resource length occupied by the first PBCH on the second time domain symbol in the first information block.

[0277] The second PBCH occupies less frequency domain resources on the third time-domain symbol in the second information block than the first PBCH occupies on the third time-domain symbol in the first information block.

[0278] The frequency domain resources occupied by the second PBCH in the second information block are located differently from those occupied by the first PBCH in the first information block, including:

[0279] The position of the frequency domain resources occupied by the second PBCH on the first time domain symbol in the second information block is different from the position of the frequency domain resources occupied by the first PBCH on the first time domain symbol in the first information block (including the start and end positions).

[0280] The position of the frequency domain resources occupied by the second PBCH on the second time domain symbol in the second information block is different from the position of the frequency domain resources occupied by the first PBCH on the second time domain symbol in the first information block (including the start and end positions).

[0281] The position of the frequency domain resources occupied by the second PBCH on the third time-domain symbol in the second information block is different from the position of the frequency domain resources occupied by the first PBCH on the third time-domain symbol in the first information block (including the start and end positions).

[0282] In the second information block shown in Figure 2B b), the amount of time-domain resources occupied by the second PBCH is the same as the amount of time-domain resources occupied by the first PBCH in the first information block shown in Figure 2B a). Furthermore, the position of the time-domain resources occupied by the second PBCH in the second information block shown in Figure 2B b) is the same as the position of the time-domain resources occupied by the first PBCH in the first information block shown in Figure 2B a).

[0283] In the second information block shown in Figure 2B b), the amount of time-domain resources occupied by the second PBCH is the same as that occupied by the first PBCH in the first information block shown in Figure 2B a), including:

[0284] In the second information block shown in Figure 2B b), the number of time-domain symbols occupied by the second PBCH is the same as the number of time-domain symbols occupied by the first PBCH in the first information block shown in Figure 2B a).

[0285] In the second information block shown in Figure 2B b), the temporal resources occupied by the second PBCH are located in the same position as those occupied by the first PBCH in the first information block shown in Figure 2B a), including:

[0286] In the second information block shown in Figure 2B b), the position of the time-domain symbol occupied by the second PBCH in the second information block is the same as the position of the time-domain symbol occupied by the first PBCH in the first information block shown in Figure 2B a).

[0287] Furthermore, the second PBCH in the second information block shown in Figure 2B b) occupies multiple time-domain symbols and satisfies the following conditions:

[0288] On each time-domain symbol, the frequency-domain resources occupied by the second PBCH have the same start and end positions in the second information block;

[0289] The frequency domain resources occupied by the second PBCH on each time domain symbol are symmetrical based on the center frequency, which is the middle position of the frequency domain resources occupied by the second information block.

[0290] If the second information block shown in Figure 2B b) and the first information block shown in Figure 2B a) are both rate-matched using the time-frequency domain resources corresponding to the first information block shown in Figure 2B a), then the second information block shown in Figure 2B b) has a section without data at the beginning and end of OFDM symbols 0-3. Therefore, from the waveform perspective, the second information block shown in Figure 2B b) is different from the first information block shown in Figure 2B a). This waveform difference allows the terminal 101 to distinguish between the two information blocks.

[0291] In Figure 2B, the pattern of the second information block shown in Figure 2B c) differs from the pattern of the first information block shown in Figure 2B a), including:

[0292] The amount of frequency domain resources occupied by the second PBCH is different from the amount of frequency domain resources occupied by the first PBCH;

[0293] The frequency domain resources occupied by the second PBCH are located in the second information block in a different position than the frequency domain resources occupied by the first PBCH in the first information block.

[0294] The amount of frequency domain resources occupied by the second PBCH differs from that occupied by the first PBCH, including:

[0295] The second PBCH occupies a shorter frequency domain resource length on the second time domain symbol in the second information block than the first PBCH occupies a shorter frequency domain resource length on the second time domain symbol in the first information block.

[0296] The frequency domain resources occupied by the second PBCH in the second information block are located differently from those occupied by the first PBCH in the first information block, including:

[0297] The position of the frequency domain resources occupied by the second PBCH on the second time domain symbol in the second information block is different from the position of the frequency domain resources occupied by the first PBCH on the second time domain symbol in the first information block (including the start and end positions).

[0298] In the second information block shown in Figure 2B c), the amount of time-domain resources occupied by the second PBCH is the same as the amount of time-domain resources occupied by the first PBCH in the first information block shown in Figure 2B a). Furthermore, the position of the time-domain resources occupied by the second PBCH in the second information block shown in Figure 2B c) is the same as the position of the time-domain resources occupied by the first PBCH in the first information block shown in Figure 2B a).

[0299] In the second information block shown in Figure 2B c), the amount of time-domain resources occupied by the second PBCH is the same as that occupied by the first PBCH in the first information block shown in Figure 2B a), including:

[0300] In the second information block shown in Figure 2B c), the number of time-domain symbols occupied by the second PBCH is the same as the number of time-domain symbols occupied by the first PBCH in the first information block shown in Figure 2B a).

[0301] In the second information block shown in Figure 2B c), the temporal resources occupied by the second PBCH are located in the same position as those occupied by the first PBCH in the first information block shown in Figure 2B a), including:

[0302] In the second information block shown in Figure 2B c), the position of the time-domain symbol occupied by the second PBCH in the second information block is the same as the position of the time-domain symbol occupied by the first PBCH in the first information block shown in Figure 2B a).

[0303] Furthermore, the second PBCH in the second information block shown in Figure 2B c) occupies multiple time-domain symbols and satisfies the following conditions:

[0304] The position of the frequency domain resources occupied by the second PBCH on the second time domain symbol in the second information block is different from the position of the frequency domain resources occupied by the second PBCH on other time domain symbols (the first time domain symbol and the third time domain symbol) in the second information block (including the start position and the end position);

[0305] The frequency domain resources occupied by the second PBCH on each time domain symbol are symmetrical based on the center frequency, which is the middle position of the frequency domain resources occupied by the second information block.

[0306] If the second information block shown in Figure 2B c) and the first information block shown in Figure 2B a) are both rate-matched using the time-frequency domain resources corresponding to the first information block shown in Figure 2B a), then the second information block shown in Figure 2B c) will have a section without data at the beginning and end of OFDM symbol 2. Therefore, from the waveform perspective, the second information block shown in Figure 2B c) is different from the first information block shown in Figure 2B a). This waveform difference allows terminal 101 to distinguish between the two information blocks.

[0307] It should be noted that in Figure 2B, the frequency domain position of PBCH in each information block is symmetrical about the center frequency in each Symbol, but the possibility of non-symmetry about the center frequency cannot be ruled out.

[0308] It is understood that the OFDM symbols 0, 1, 2, and 3 mentioned in the embodiments of this application are relative to an information block and are not necessarily equal to the OFDM symbol numbers occupied by that information block during actual transmission.

[0309] In some embodiments, the pattern of the first information block differs from the pattern of the second information block, including at least one of the following:

[0310] The amount of time-frequency domain resources occupied by the second synchronization signal is different from the amount of time-frequency domain resources occupied by the first synchronization signal.

[0311] The position of the time-frequency domain resources occupied by the second synchronization signal in the second information block is different from the position of the time-frequency domain resources occupied by the first synchronization signal in the first information block.

[0312] In some embodiments, the amount of time-frequency domain resources occupied by the second synchronization signal is different from the amount of time-frequency domain resources occupied by the first synchronization signal, including at least one of the following:

[0313] The amount of time-domain resources occupied by the second synchronization signal is different from the amount of time-domain resources occupied by the first synchronization signal.

[0314] The amount of frequency domain resources occupied by the second synchronization signal is different from the amount of frequency domain resources occupied by the first synchronization signal.

[0315] Optionally, the time-domain resources occupied by the second synchronization signal can be a subset of the time-domain resources occupied by the first synchronization signal, so that the amount of time-domain resources occupied by the second synchronization signal can be less than the amount of time-domain resources occupied by the first synchronization signal.

[0316] Optionally, the first synchronization signal carries first system information, and the second synchronization signal carries second system information. The second system information can be simplified system information compared to the first system information, so that the amount of frequency domain resources occupied by the second synchronization signal can be less than the amount of frequency domain resources occupied by the first synchronization signal.

[0317] In some embodiments, the position of the time-frequency domain resources occupied by the second synchronization signal in the second information block is different from the position of the time-frequency domain resources occupied by the first synchronization signal in the first information block, including at least one of the following:

[0321] Optionally, the position of the frequency domain resources occupied by the second synchronization signal in the second information block can be a subset of the position of the frequency domain resources occupied by the first synchronization signal in the first information block.

[0322] It should be noted that when the first information block and the second information block are rate matched, the same time-frequency domain resources are used for rate matching. Therefore, because the amount of time-frequency domain resources occupied by the second synchronization signal is different from the amount occupied by the first synchronization signal, and / or the position of the time-frequency domain resources occupied by the second synchronization signal in the second information block is different from the position of the time-frequency domain resources occupied by the first synchronization signal in the first information block, the waveform of the second information block is different from the waveform of the first information block. This waveform difference allows the terminal 101 to distinguish between the two information blocks.

[0323] In some embodiments, the amount of time-frequency domain resources occupied by the second synchronization signal is different from the amount of time-frequency domain resources occupied by the first synchronization signal, including at least one of the following:

[0326] Optionally, the time-domain symbols occupied by the second synchronization signal can be a subset of the time-domain symbols occupied by the first synchronization signal, so that the number of time-domain symbols occupied by the second synchronization signal can be less than the number of time-domain symbols occupied by the first synchronization signal.

[0327] Optionally, the length of the frequency domain resources occupied by the second synchronization signal on the i-th time domain symbol in the second information block may be less than the length of the frequency domain resources occupied by the first synchronization signal on the i-th time domain symbol in the first information block, wherein i is a non-negative integer less than m, and m is the smaller value between the number of time domain symbols contained in the second information block and the number of time domain symbols contained in the first information block.

[0328] In some embodiments, the position of the time-frequency domain resources occupied by the second synchronization signal in the second information block is different from the position of the time-frequency domain resources occupied by the first synchronization signal in the first information block, including at least one of the following:

[0329] The position of the time domain symbol occupied by the second synchronization signal in the second information block is different from the position of the time domain symbol occupied by the first synchronization signal in the first information block;

[0330] The position of the frequency domain resources occupied by the second synchronization signal on the i-th time domain symbol in the second information block is different from the position of the frequency domain resources occupied by the first synchronization signal on the i-th time domain symbol in the first information block. The position includes at least one of the start position and the end position, where i is a non-negative integer less than m, and m is the smaller value between the number of time domain symbols occupied by the second synchronization signal and the number of time domain symbols occupied by the first synchronization signal.

[0331] It is understood that if the length of the frequency domain resources occupied by the second synchronization signal on the i-th time domain symbol in the second information block is different from the length of the frequency domain resources occupied by the first synchronization signal on the i-th time domain symbol in the first information block, then the starting position of the frequency domain resources occupied by the second synchronization signal on the i-th time domain symbol in the second information block is different from the starting position of the frequency domain resources occupied by the first synchronization signal on the i-th time domain symbol in the first information block, and / or, the ending position of the frequency domain resources occupied by the second synchronization signal on the i-th time domain symbol in the second information block is different from the ending position of the frequency domain resources occupied by the first synchronization signal on the i-th time domain symbol in the first information block.

[0332] In some embodiments, the second synchronization signal includes at least one of the primary synchronization signal PSS and the secondary synchronization signal SSS.

[0333] In some embodiments, the number of PSSs in the second information block is one or more;

[0334] One of the aforementioned PSS is located in any one of the multiple time domain symbols occupied by the aforementioned second information block;

[0335] The subcarrier located in the middle position of the frequency domain resources occupied by each of the above PSSs has the same or different frequency domain position in the second information block as the center frequency of the second information block, where the center frequency is the middle position of the frequency domain resources occupied by the second information block.

[0340] In Figure 2C, the second information block contains only PSS. The number of PSS can be one or more.

[0341] Optionally, the time-domain location of the PSS can be any symbol in the second information block.

[0342] Optionally, the time-domain location of the PSS can be on symbol 0 in the second information block. As shown in Figure 2C(a), the second information block includes only one PSS, which can be located on Symbol 0; or, as shown in Figure 2C(b), the second information block includes two PSSs, which can be located on Symbol 0 and Symbol 2 respectively; or, as shown in Figure 2C(c), the second information block includes two PSSs, which can be located on Symbol 0 and Symbol 1 respectively.

[0343] Optionally, the frequency domain position of the PSS can be in the middle of the second information block or at other frequency domain positions.

[0344] In some embodiments, the number of SSS in the second information block is one or more;

[0345] One of the aforementioned SSS is located in any one of the multiple time domain symbols occupied by the aforementioned second information block;

[0346] The subcarrier located in the middle position of the frequency domain resources occupied by each of the above-mentioned SSSs has the same or different frequency domain position in the above-mentioned second information block from the center frequency of the above-mentioned second information block, where the center frequency is the middle position of the frequency domain resources occupied by the above-mentioned second information block.

[0347] Optionally, the second information block mentioned above includes at least one SSS.

[0348] Optionally, if the second information block occupies multiple time-domain symbols of Symbol 0-3, then one of the aforementioned SSSs in the second information block is located in any one of Symbol 0-3. Optionally, the aforementioned SSS in the second information block can be located in Symbol 2.

[0349] Optionally, in the second information block, the subcarrier located in the middle position of the frequency domain resources occupied by each SSS is either at the center frequency of the second information block (possibly differing by one subcarrier) or not at the center frequency of the second information block.

[0350] Figure 2D is a schematic diagram of the second information block provided in an embodiment of this application.

[0351] In Figure 2D, the second information block contains only SSS. The number of SSS can be one or more.

[0352] Optionally, the time-domain location of the SSS can be any symbol in the second information block.

[0353] Optionally, the time-domain location of the SSS can be on symbol 2 in the second information block. As shown in Figure 2D(a), the second information block includes only one SSS, which can be located on Symbol 2; or, as shown in Figure 2D(b), the second information block includes two SSSs, which can be located on Symbol 0 and Symbol 2 respectively; or, as shown in Figure 2D(c), the second information block includes two SSSs, which can be located on Symbol 1 and Symbol 2 respectively.

[0354] Optionally, the frequency domain position of the SSS can be in the middle of the second information block or at other frequency domain positions.

[0355] In some embodiments, the second information block includes at least one PSS and at least one SSS; satisfying any of the following:

[0356] The PSS and SSS mentioned above are time-division multiplexed;

[0357] The PSS and SSS mentioned above are frequency division multiplexed;

[0358] The PSS and SSS mentioned above have different time-domain and frequency-domain positions in the second information block.

[0359] In the above embodiments, Time Division Multiplexing (TDM) refers to a situation where, within a second information block, the PSS and SSS can occupy different time-domain symbols, and the frequency domain resources occupied by the PSS within the second information block are located at the same position as those occupied by the SSS. For example, the PSS can occupy Symbol 0 and Symbol 1 in the second information block, and the SSS can occupy Symbol 2. Furthermore, the PSS on Symbol 0 and Symbol 1, and the SSS on Symbol 2, all occupy subcarriers from the p-th subcarrier on the a-th PRB to the q-th subcarrier on the b-th PRB within the second information block in the frequency domain. Here, a, b, p, and q are all non-negative integers, with b greater than a, the value of b less than the number of PRBs occupied by the second information block, and the values ​​of p and q less than the number of subcarriers included in each PRB.

[0360] In the above embodiments, Frequency Division Multiplexing (FDM) refers to a situation where, within a second information block, the PSS and SSS can occupy the same time-domain symbol (i.e., a time-domain symbol can simultaneously contain both PSS and SSS), but the position of the frequency-domain resources occupied by the PSS within the information block differs from the position of the frequency-domain resources occupied by the SSS. For example, both PSS and SSS can occupy Symbol 0 in the second information block, but the PSS and SSS on that Symbol are located differently in the frequency domain and do not overlap.

[0361] In the above embodiments, the time domain position and frequency domain position of the PSS and the SSS in the second information block are different. This can mean that in a second information block, the PSS and SSS can occupy different time domain symbols, and the position of the frequency domain resources occupied by the PSS in the information block is different from the position of the frequency domain resources occupied by the SSS in the information block.

[0362] Figure 2E is a schematic diagram of the second information block provided in an embodiment of this application.

[0364] Optionally, the time domain location of the PSS can be any symbol in the second information block. The time domain location of the SSS can be any symbol in the second information block. The time domain location of the PSS and the time domain location of the SSS may not coincide.

[0365] Optionally, the time-domain location of the PSS can be on symbol 0 in the second information block, and the time-domain location of the PSS can be on symbol 2 in the second information block. As shown in Figure 2E(a), the second information block includes one PSS and one SSS, where the PSS can be located on Symbol 0 and the SSS can be located on Symbol 2. Or, as shown in Figure 2D(b), the second information block includes one PSS and one SSS, where the PSS can be located on Symbol 0 and the SSS can be located on Symbol 1. Or, as shown in Figure 2D(c), the second information block includes two PSSs and one SSS, where the two PSSs can be located on Symbol 0 and Symbol 1 respectively, and the one SSS can be located on Symbol 2. Or, as shown in Figure 2D(d), the second information block includes one PSS and two SSSs, where the one PSS can be located on Symbol 0 and the two SSSs can be located on Symbol 2 and Symbol 3 respectively.

[0366] Optionally, the frequency domain position of the PSS can be in the middle of the second information block or at other frequency domain positions. The frequency domain position of the SSS can also be in the middle of the second information block or at other frequency domain positions. The frequency domain positions of the PSS and SSS do not have to coincide.

[0367] It is understood that in the above embodiments, for an information block, the PSS and SSS cannot occupy the same RE.

[0368] In some embodiments, the starting position of the frequency domain resources occupied by the second PBCH and / or the second synchronization signal in the second information block on each time domain symbol is determined based on a reference point and an offset.

[0369] The reference point mentioned above can be any of the following:

[0370] The subcarrier with the lowest frequency among the frequency domain resources occupied by the second information block mentioned above;

[0371] The subcarrier with the lowest frequency among the frequency domain resources occupied by the first information block mentioned above;

[0372] The lowest frequency subcarrier in the lowest frequency physical resource block (PRB) among the frequency domain resources occupied by the second information block mentioned above.

[0373] The lowest frequency subcarrier in the lowest frequency PRB among the frequency domain resources occupied by the first information block mentioned above;

[0374] The reference frequency domain location agreed upon in the agreement.

[0375] In some embodiments, the offset is used to indicate the frequency interval between the starting position of the frequency domain resources occupied by the second PBCH in the second information block on each time domain symbol and the reference point; and / or,

[0376] The aforementioned offset is used to indicate the frequency interval between the starting position of the frequency domain resources occupied by the aforementioned second synchronization signal in the aforementioned second information block and the aforementioned reference point on each time domain symbol.

[0377] The offsets mentioned above may be the same or different for each time-domain symbol.

[0378] Optionally, the aforementioned reference point can be any fixed point, which is independent of the first and second information blocks and is a reference frequency domain position agreed upon by the protocol. For example, the aforementioned fixed point can be CRB0, the start position of BWP, the position of the synchronization grid, etc.

[0409] The following is an exemplary description of the methods described in the above embodiments.

[0410] In some embodiments, the network device transmits at least one of a full-function information block (including a synchronization signal and a PBCH) (first information block) and a lightweight function information block (containing only a synchronization signal, or only a PBCH) (second information block). The full-function information block and the lightweight function information block are distinguished by different patterns.

[0411] In some embodiments, the PBCH carries system information, and the lightweight functional information block transmits simplified system information. Therefore, the frequency domain PRB occupied by the PBCH in the lightweight functional information block is less than that occupied by the PBCH in the full-function information block. However, the lightweight functional information block still uses the time-frequency domain resources of the full-function information block for rate matching. Therefore, when the terminal receives data, the full-function information block and the lightweight functional information block have different shapes, so they can be distinguished.

[0412] In some embodiments, the time domain symbols occupied by the PBCH in the lightweight functional information block are the same as those occupied by the PBCH in the full functional information block, or the time domain symbols occupied by the PBCH in the lightweight functional information block are a subset of those occupied by the PBCH in the full functional information block.

[0413] In some embodiments, the PBCH in the lightweight functional information block differs in frequency domain position from that in the full functional information block at at least one time domain symbol. Optionally, this may include at least one of the following: different start position, different end position, or different PRB length.

[0414] In some embodiments, the frequency domain position of each time-domain symbol in the PBCH of the lightweight functional information block is defined relative to the reference information block, wherein the reference information block can be a lightweight functional information block or a full-function information block.

[0415] In some embodiments, the starting position of the frequency domain resources occupied by the PBCH and / or synchronization signal on each symbol in the lightweight functional information block within the aforementioned second information block is determined based on a reference point and an offset. The reference point is:

[0416] a) The lowest frequency subcarrier among the frequency domain resources occupied by the reference information block;

[0417] b) The lowest frequency subcarrier in the lowest frequency PRB among the frequency domain resources occupied by the reference information block.

[0418] In some embodiments, the frequency domain resources occupied by the PBCH on each time-domain symbol in the lightweight functional information block have the same start position and / or the same end position in the lightweight functional information block. Here, the start position refers to the lowest subcarrier position among the frequency domain resources occupied by the PBCH on that time-domain symbol, and the end position refers to the highest subcarrier position among the frequency domain resources occupied by the PBCH on that time-domain symbol.

[0419] In some embodiments, the frequency domain resources occupied by the PBCH on each time domain symbol in the lightweight functional information block are at least one different from the start position and the end position in the lightweight functional information block.

[0420] In some embodiments, the number of PRBs occupied by the PBCH in the lightweight functional information block on each time domain symbol is symmetrical about the center frequency.

[0421] In some embodiments, at least one of PSS and SSS is sent in the lightweight function information block:

[0422] a) Send at least one SSS:

[0423] The time domain position of SSS is any one of Symbol 0-3, and in particular, it is the second Symbol;

[0424] The frequency domain position of the SSS is at the center frequency of the lightweight functional information block (may be one subcarrier off), or it is not at the center frequency of the lightweight functional information block. The center frequency is the middle position of the frequency domain resources occupied by the lightweight functional information block.

[0425] b) Send at least one PSS:

[0426] The time domain position of PSS is any one of Symbol 0-3, specifically the 0th Symbol;

[0427] The frequency domain position of the PSS is at the center frequency of the lightweight functional information block (may be one subcarrier off), or it is not at the center frequency of the lightweight functional information block. The center frequency is the middle position of the frequency domain resources occupied by the lightweight functional information block.

The technical features of different feasible implementations in this embodiment can be combined to form new optional implementations based on their inherent logical relationships.

[0429] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0430] This application also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed, which includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed, which includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0431] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits.

For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
