AI Technical Summary
In the existing technology, the second and third bits of the SFN indication information of the synchronization signal block are not scrambled, which causes the terminal device to be able to receive only 4 PBCHs within 80 milliseconds, thus failing to further improve the reception quality.
By introducing at least two unscrambled bits into the SFN indication information, the network device is used to indicate the number of times the PBCH is repeatedly transmitted within the maximum duration of PBCH combined reception by the terminal device. The at least two bits include bits with an index greater than 3 in the SFN indication information.
This increases the expected period of PBCH reception for terminal devices, improving reception quality. For example, it allows for the combined reception of four PBCHs within 160 milliseconds, significantly enhancing the signal-to-noise ratio.

For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field." Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the object being described is "device", then "first device" and "second device" can be the same device or different devices, and their types can be the same or different. Similarly, if the object being described is "information", then "first information" and "second information" can be the same information or different information, and their content can be the same or different.

[0178] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.
[0179] The following explains the terminology used in the embodiments of this disclosure.
[0180] Terminal devices include, but are not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet, 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, and wireless terminal device in smart home.
[0181] Network equipment includes, for example, nodes or devices that connect terminal devices to a wireless network. Network equipment can be satellites, spaceborne base stations, or base stations. Base stations can be at least one of the following in 5G communication systems: evolved NodeB (eNB), next-generation eNB (ng-eNB), next-generation NodeB (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul equipment, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in 6G communication systems, open RAN, cloud RAN, base stations in other communication systems, and access nodes in Wi-Fi systems, but are not limited to these.
[0182] Beam hopping is a technique that adjusts the beam direction at different times to improve the coverage and efficiency of satellite communications. Addressing the imbalance between supply and demand in satellite coverage areas is a current research direction in the evolution of Non-Terrestrial Networks (NTNs). By adjusting the duration of beam coverage (or beam position) and the beam period, different capacity values are provided to balance the requirements of different coverage areas.
[0183] A synchronization signal block (SSB) is a signal block periodically sent by network devices to terminal devices. It assists terminal devices in cell search, timing and frequency synchronization, location and mobility management, and other functions. The SSB includes primary synchronization signals (PSS), secondary synchronization signals (SSS), and the physical broadcast channel (PBCH).
[0184] Currently, related technologies use SSB cycles to support public information (such as SSB, PBCH, etc.) to achieve wide coverage of the target ground area. That is, within one SSB cycle (e.g., 20ms), only some coverage areas of multiple coverage areas of the network device have beams to provide services to the terminal device.
[0185] The following explanation, with reference to Figure 1a, illustrates the use of SSB periodicity to support the beam skipping mechanism.
[0186] Figure 1a is an exemplary architecture diagram of a beam-hopping mechanism according to an embodiment of this disclosure. As shown in Figure 1a, the network device has multiple coverage areas, including coverage areas 10a, 10b, 10c, and 10d.
[0187] For example, based on the beam hopping mechanism, the network device sends SSB 1 to coverage area 10a in the first SSB cycle, SSB 2 to coverage area 10b in the second SSB cycle, SSB 3 to coverage area 10c in the third SSB cycle, and SSB 4 to coverage area 10d in the fourth SSB cycle.
[0188] In related technologies, the SSB period is 20 milliseconds (ms). It is understood that when the terminal device is located in coverage area 10a, it receives SSB 1 from the network device within the SSB period. To receive SSB 1 again from the network device, it must wait until the next SSB period.
[0189] The SSB sent by network devices to terminal devices includes the PBCH. The PBCH can be used to carry the Master Information Block (MIB), which includes System Frame Number (SFN) indication information. The PBCH has 32 bits, of which 24 bits are provided by higher-layer parameters and are related to the MIB, and the remaining 8 bits are provided by the physical layer.
[0190] Of these 32 bits, 10 bits (SFN indication information) are related to the SFN, the 6 most significant bits (MSB) of these 10 bits are in the MIB-related bits, and the 4 least significant bits (LSB) of these 10 bits are in the bits provided by the physical layer. These 10 bits can indicate 1024 frames.
[0191] After receiving the PBCH, the network device will perform operations such as interleaving, scrambling, channel coding, rate matching, rescrambling, and modulation on the PBCH.
[0192] The scrambling rules for this 32-bit sequence are explained below: In the bit sequence a0, a1, a2...aA-1 The scrambling is a′0, a′1, a′2……a′ A-1 , where a′ i =(a i +S i ) mod 2, where i = 0, 1, ..., A-1. S i Generate according to the following rules: in a i =a1 or a i When = a2, S i =0; in a i ≠ a1 or a i When ≠a2, j is an integer that varies with i, and v is obtained from Table 1 below based on the second (2nd) and third (3rd) bits of the four least significant bits in the 10 bits related to SFN. or When, m = A - 3; in When, m = A - 4; in When, m = A - 5; in At that time, m = A - 6; where, This represents the number of candidate SSBs in a half-frame.
[0193] Table 1
[0194] From the above scrambling process, it can be concluded that for the second bit (2) of the four least significant bits in the 10 bits related to SFN, nd ) and the third bit (3 rd No scrambling is performed. In this way, when the terminal device needs to decode, it can receive the four PBCHs sent by the network device within 80ms in a combined manner, and determine the scrambling sequence based on the second bit, the third bit and the identifier (ID) of the cell where the terminal device is located, and then descramble it according to the sequence.
[0195] In order for the terminal device to receive 4 PBCHs within 80ms, the lower 3 bits of the 10 bits related to SFN are usually used to indicate these 80ms (2 3 ×10ms, where 10ms represents the duration of a frame), and the second and third bits of the lower 3 bits are used to indicate these 4 PBCHs without scrambling.
[0196] The following, with reference to Figure 1b, explains how to merge the four received PBCHs within 80ms.
[0197] Figure 1b is a schematic diagram of an exemplary architecture for supporting beam hopping mechanisms using SSB cycles according to an embodiment of this disclosure. As shown in Figure 1b, exemplaryly, the lower 3 bits are 000 (where 2 nd 0, 3 rd(0) Receive the 0th frame at 0ms, the lower 3 bits are 010 (where, 2) nd For 1, 3 rd The second frame is received in 20ms (where 2 is 0), and the lower 3 bits are 100 (where 2 is 0). nd 0, 3 rd 1) The 4th frame is received in 40ms, and the lower 3 bits are 110 (where, 2 nd For 1, 3 rd 1) Receive the 6th frame in 60ms.
[0198] Among them, the 0th frame, the 2nd frame, the 4th frame and the 6th frame are four frames received by merging within 80ms. Each frame includes one PBCH, that is, four PBCHs received by merging within 80ms.
[0199] Therefore, in the above-mentioned related technologies, the second and third bits are not scrambled, and only support the terminal device to combine and receive 4 PBCHs within 80ms. To improve the reception quality of the terminal device (e.g., signal-to-noise ratio, SNR), it is usually necessary to increase the SSB period. For example, in NTN, the SSB period needs to be increased from 20ms to 40ms. How to enable the terminal device to combine and receive 4 or more PBCHs has become an urgent technical problem to be solved.
[0200] To address the aforementioned issues, this disclosure provides a communication method, apparatus, system, storage medium, and program product. In this method, the PBCH is received in a manner with a longer SSB period by not scrambling other bits in the SFN, instead of the second and third bits.
[0201] The communication methods, apparatus, systems, storage media, and program products provided in this disclosure are described in detail below with reference to the accompanying drawings.
[0202] Referring to Figure 2, which is an exemplary flowchart of a communication method provided according to an embodiment of the present disclosure, the communication method includes the following steps:
[0203] In step S2101, the network device sends the PBCH to the terminal device. Correspondingly, the terminal device receives the PBCH.
[0204] In some embodiments, the network device sends an SSB to the terminal device, and the terminal device receives the SSB, which includes a PBCH.
[0205] In some embodiments, the SFN indication information of the PBCH includes at least two unscrambled bits.
[0206] In some embodiments, at least two bits are carried in the payload information of the PBCH. This payload information is provided by the physical layer.
[0207] In some embodiments, at least two bits are consecutive bits in the SFN indication information.
[0208] In some embodiments, the number of at least two bits is related to the number of bits in the SFN indication information. For example, the number of at least two bits is less than the number of bits in the SFN indication information. For example, when the number of bits in the SFN indication information is 10, the number of at least two bits can be 2, 3, or 4, etc.
[0209] In some embodiments, at least two bits are used to indicate the number of times the network device retransmits the PBCH to the terminal device within the maximum duration of the terminal device's PBCH merge reception.
[0210] In some embodiments, the maximum duration is the maximum duration for the terminal device to perform PBCH merging and reception.
[0211] In some embodiments, at least two bits are indexed in the SFN indication information to indicate the maximum duration.
[0212] In some embodiments, at least two bits include a first bit. The first bit is the most significant bit of the at least two bits. The index of the first bit in the SFN indication information is used to indicate the maximum duration.
[0213] In some embodiments, the maximum duration is 2 K ×T. Where K is the index of the first bit in the SFN indication information, and T is the unit duration. K is a positive integer, and T is a positive integer.
[0214] In some embodiments, K is related to the number of bits in the SFN indication information. In some embodiments, K is less than or equal to the number of bits in the SFN indication information. For example, if the number of bits in the SFN indication information is 10, K can be 4, 5, 6, 7, 8, 9, or 10. For example, if the number of bits in the SFN indication information is 11, K can be 4, 5, 6, 7, 8, 9, or 11.
[0215] For example, T can be 10ms or 20ms, etc.
[0216] In some embodiments, at least two bits contain a bit with an index greater than 3 in the SFN indication information.
[0217] In some embodiments, when the number of bits in the SFN indication information is 10 and at least two bits include two bits, if the at least two bits consist of a first bit and a second bit, then the index of the first bit and the second bit is as shown in Examples 1A to 1G below.
[0218] Example 1A: The index of the second bit in the SFN indication information is 3, and the index of the first bit in the SFN indication information is 4.
[0219] In Example 1B, the index of the second bit in the SFN indication information is 4, and the index of the first bit in the SFN indication information is 5.
[0220] Example 1C: The index of the second bit in the SFN indication information is 5, and the index of the first bit in the SFN indication information is 5.
[0221] In Example 1D, the index of the second bit in the SFN indication information is 6, and the index of the first bit in the SFN indication information is 7.
[0222] In Example 1E, the index of the second bit in the SFN indication information is 7, and the index of the first bit in the SFN indication information is 8.
[0223] In Example 1F, the index of the second bit in the SFN indication information is 8, and the index of the first bit in the SFN indication information is 9.
[0224] In Example 1G, the index of the second bit in the SFN indication information is 9, and the index of the first bit in the SFN indication information is 10.
[0225] The first bit and the maximum duration are explained below with reference to Examples 2A to 2D.
[0226] Example 2A, based on Example 1A, has the first bit indexed as 4 in the SFN indication information, and the maximum duration is 160ms.
[0227] Example 2B, based on Example 1B, has the first bit indexed as 5 in the SFN indication information, and the maximum duration is 320ms.
[0228] Example 2C, based on Example 1C, has the first bit indexed as 6 in the SFN indication information, and the maximum duration is 640ms.
[0229] Example 2D, based on Example 1D, has the first bit indexed as 7 in the SFN indication information, and the maximum duration is 1280ms.
[0230] In some embodiments, at least two bits comprise C bits, where C is an integer greater than or equal to 2.
[0231] In some embodiments, the "C" in the C bits is used to indicate the maximum number of PBCH merge receptions that the terminal device expects to perform.
[0232] In some embodiments, the "C" in the C bits satisfies the following condition with respect to the maximum number M of PBCH combining receptions expected by the terminal: 2 C =M, where M is a positive integer.
[0233] In some embodiments, C = 2, M = 4.
[0234] In some embodiments, C = 3 and M = 8.
[0235] In some embodiments, C = 4 and M = 16.
[0236] When the maximum number of PBCH merging receptions is M, the network device sends M PBCHs to the terminal device, and the terminal device merges and receives M PBCHs.
[0237] In some embodiments, the maximum duration is M×N, where N is the period during which the terminal device expects to receive the PBCH, and N is a positive integer. For example, N may also be referred to as the SSB period or the SSB extended period, etc.
[0238] In some embodiments, M is 4 and N is greater than 20ms. For example, M is 4 and N can be 40ms, 80ms, 160ms, 320ms, 640ms, or 1280ms, etc.
[0239] The following describes the number of times the terminal device expects to receive PBCH in combination (or the maximum number of times the terminal device expects to receive PBCH in combination), the period during which the terminal device expects to receive PBCH, and the maximum duration, when the number of at least two bits is 2, in conjunction with Examples 3A to 3G.

[0260] In the embodiments of this application, at least two unscrambled bits, including bits with an index greater than 3 in the SFN indication information, can enable the terminal device to perform PBCH combining reception according to a longer SSB period (i.e., the period during which the terminal device expects to receive PBCH), thereby improving the reception quality of the terminal device (e.g., signal-to-noise ratio (SNR)).
[0261] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

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.
