[0039] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0040] The steps illustrated in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in a different order than that presented here.

[0041] In 5G systems, terminals perform cell search based on the Synchronization Signal / Physical Broadcast Channel Block (SSB). The SSB achieves narrow-beam polling through repeated transmissions, thereby achieving coverage of the entire cell. After the terminal is powered on, it scans the SSB on each narrow beam to obtain the optimal beam, completes the cell search, and then accesses the network.

[0042] In 5G systems, the time-frequency structure of SSB is as follows: Figure 1 As shown, Figure 1 The diagram illustrates the time-frequency structure of the SSB (Secondary Synchronization Signal) in the existing technology. The SSB consists of the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), the Physical Broadcast Channel Block (PBCH), and its Demodulation Reference Signal (DMRS). The SSB occupies four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain and 240 consecutive subcarriers in the frequency domain. Assuming OFDM symbol indices range from 0 to 3 and subcarrier indices range from 0 to 239, the specific resource allocation of the PSS, SSS, PBCH, and DMRS within the SSB is as follows:

[0043] The PSS is located on symbol 0, occupying subcarriers 56 to 182, for a total of 127 subcarriers.

[0044] SSS is located on symbol 2, occupying subcarriers 56 to 182, for a total of 127 subcarriers.

[0045] PBCH, including PBCH DMRS and PBCH data, is located on symbols 1, 2, and 3.

[0046] On symbol 1, subcarriers 0 to 239 are occupied, totaling 240 subcarriers; on symbol 2, subcarriers 0 to 47 and subcarriers 192 to 239 are occupied, totaling 96 subcarriers; on symbol 3, subcarriers 0 to 239 are occupied, totaling 240 subcarriers.

[0047] The DMRS is located in the middle of the PBCH, and its frequency domain density is 1 / 4, that is, there is 1 DMRS in every 4 PBCH REs.

[0048] To meet the measurement requirements of high-speed mobile terminals, synchronization signals need to be transmitted at high density. However, the system message change cycle carried by the physical broadcast channel is usually quite large. Since the SSB is transmitted as a whole, the transmission of synchronization signals inevitably involves the transmission of physical broadcast channels, leading to unnecessary resource waste, limiting dynamic time-domain shutdown operations, increasing network power consumption, and hindering network energy conservation. Therefore, the method of transmitting synchronization signals and physical broadcast channels with the same cycle is no longer applicable in 6G systems. New methods for transmitting synchronization signals and physical broadcast channels need to be designed to achieve more flexible resource utilization, avoid resource waste, enable more flexible time-domain shutdown, and achieve network energy conservation.

[0049] In 4G systems, the primary and secondary synchronization channels have a fixed period of 5ms and a fixed location, situated in the last two time domain symbols of the first time slot, with the same frequency domain bandwidth per symbol. The PBCH has a fixed period of 10ms and is located in the first four time domain symbols of the second time slot, with the same frequency domain bandwidth per symbol. The fixed period and fixed location of the primary and secondary synchronization channels and PBCH in 4G systems lead to wasted network resources and prevent the network from flexibly shutting down in the time domain to achieve energy savings.

[0050] In one embodiment, Figure 2 A flowchart of a channel transmission method provided in an embodiment of this application is shown below. Figure 2 As shown, the method provided in this embodiment can be applied to a terminal device. For example, the terminal device can be a user equipment (UE). Figure 2 As shown, this embodiment includes: S110-S120.

[0051] S110, Receive synchronization signals and physical broadcast channels sent by the base station.

[0052] The transmission methods of the synchronization signal and physical broadcast channel include: transmitting the synchronization signal and physical broadcast channel together in a first time slot, and transmitting the synchronization signal or physical broadcast channel separately in a second time slot; and / or transmitting the synchronization signal and physical broadcast channel according to a first shared time slot resource in the first time slot, and transmitting the synchronization signal and physical broadcast channel according to a second shared time slot resource in the second time slot; wherein the first shared time slot resource and the second shared time slot resource are different time slot resources, and the first time slot and the second time slot are different time slots.

[0053] In this embodiment, the synchronization signal may include a primary synchronization signal and / or a secondary synchronization signal. The physical broadcast channel and the synchronization signal can be transmitted simultaneously in multiple time slots. The base station can transmit the synchronization signal and the physical broadcast channel to the terminal device in any of the following ways:

[0054] Method 1: In the first time slot, the synchronization signal and the physical broadcast channel share time domain resources for transmission, while in the second time slot, the synchronization signal occupies time domain resources for transmission alone.

[0055] Here, the first time slot and the second time slot are names used to distinguish different time slots. The first time slot may include at least one time slot, and the second time slot may include at least one time slot. In some time slots, the synchronization signal and the physical broadcast channel share time domain resources for transmission, while in other time slots, the synchronization signal occupies time domain resources for transmission alone.

[0056] Method 2: In the first time slot, the synchronization signal and the physical broadcast channel share time domain resources for transmission; in the second time slot, the synchronization signal occupies time domain resources for transmission alone; and in the third time slot, the physical broadcast channel occupies time domain resources for transmission alone.

[0057] The first, second, and third time slots are designated to distinguish different time slots, and each of these slots may include at least one time slot. In some time slots, synchronization signals and physical broadcast channels can share time-domain resources for transmission; in other time slots, synchronization signals can be transmitted using time-domain resources independently; and in still other time slots, the physical broadcast channel can be transmitted using time-domain resources independently.

[0058] In both of the above methods, time-domain resources can include multiple different time-domain resources. On some time-domain resources, the physical broadcast channel and the synchronization signal can share consecutive time-domain symbols for transmission. On other time-domain resources, the physical broadcast channel and the synchronization signal can each occupy consecutive time-domain symbols for transmission, or the synchronization signal can occupy consecutive time-domain symbols for transmission, or the synchronization signal can occupy non-consecutive time-domain symbols for transmission.

[0059] Method 3: In the first time slot, the synchronization signal and the physical broadcast channel are transmitted according to the first shared time domain resources, and in the second time slot, the synchronization signal and the physical broadcast channel are transmitted according to the second shared time domain resources.

[0060] Among them, the first shared time domain resources and the second shared time domain resources are names used to distinguish different time domain resources. The first shared time domain resources and the second shared time domain resources can be understood as time domain resources shared by the physical broadcast channel and the synchronization signal.

[0061] Method 4: In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission; in the second time slot, the secondary synchronization signal and the primary synchronization signal share time domain resources for transmission; and in the third time slot, either the primary synchronization signal or the secondary synchronization signal occupies time domain resources for transmission alone.

[0062] Method 5: In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission; in the second time slot, the secondary synchronization signal occupies time domain resources for transmission alone; and in the third time slot, the primary synchronization signal occupies time domain resources for transmission alone.

[0063] Method 6: In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission; in the second time slot, the secondary synchronization signal and the physical broadcast channel share time domain resources for transmission; and in the third time slot, either the primary synchronization signal or the secondary synchronization signal occupies time domain resources for transmission alone.

[0064] Method 7: In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission; in the second time slot, the secondary synchronization signal and the physical broadcast channel share time domain resources for transmission; and in the third time slot, the secondary synchronization signal and the primary synchronization signal share time domain resources for transmission.

[0065] Method 8: In the first time slot, the auxiliary synchronization signal and the physical broadcast channel share time domain resources for transmission; in the second time slot, the auxiliary synchronization signal and the main synchronization signal share time domain resources for transmission.

[0066] Methods 9 and 3 can be used in combination with other methods. For example, Method 3 can be combined with Method 1, where the synchronization signal and physical broadcast channel are transmitted according to the first shared time domain resources in the first time slot, the synchronization signal and physical broadcast channel are transmitted according to the second shared time domain resources in the second time slot, and the synchronization signal is transmitted using time domain resources alone in the third time slot; or, Method 3 can be combined with Method 4, where the synchronization signal and physical broadcast channel are transmitted according to the first shared time domain resources in the first time slot, the synchronization signal and physical broadcast channel are transmitted according to the second shared time domain resources in the second time slot, the primary synchronization signal and secondary synchronization signal are transmitted using time domain resources together in the third time slot (there is no physical broadcast channel transmission in the third time slot), and the primary synchronization signal is transmitted using time domain resources alone in the fourth time slot (there is no physical broadcast channel or secondary synchronization transmission in the fourth time slot).

[0067] In this embodiment, the first and second shared time-domain resources differ in at least one of the following ways: the lengths of the cyclic prefixes are different; the paging prefix length of the first shared time-domain resource is a first length, for example, a short CP; the paging prefix length of the second shared time-domain resource is a second length, for example, a long CP, where the long CP is longer than the short CP; the synchronization sequences transmitted on the occupied time-domain resources are different; the lengths of the occupied time-domain resources are different; the occupied bandwidths are different; the relative positional relationships are different; and the occupied subcarrier intervals are different. Specifically, the different relative positional relationships refer to the different relative positional relationships between the synchronization signal and the physical broadcast channel in the first shared resource and the second shared time-domain resource. For example, in the first shared resource, the synchronization signal is located before the physical broadcast channel; in the second shared resource, the synchronization signal is located after the physical broadcast channel.

[0068] S120. Access the network based on the synchronization signal and / or physical broadcast channel.

[0069] In this embodiment, the existence of the synchronization signal and / or physical broadcast channel corresponding to the second shared time domain resource is indicated by the first synchronization indication information. The first synchronization indication information can be transmitted on the physical broadcast channel corresponding to the first shared time domain resource, or it can be transmitted in the SIB. The SIB includes the period and position within the time slot of the second shared time domain resource.

[0070] In this embodiment, after receiving the synchronization signal and the physical broadcast channel, the terminal device can access the 6G network based on the synchronization signal and the physical broadcast channel, or select access resources to access the 6G network based on the synchronization signal, or determine whether to access the 6G network based on the information carried in the physical broadcast channel.

[0071] When there is a synchronization signal and / or physical broadcast channel corresponding to the second shared time domain resource being transmitted, the terminal determines the access resource and accesses the network based on the synchronization signal and physical broadcast channel corresponding to the first shared time domain resource and the synchronization signal and / or physical broadcast channel corresponding to the second shared time domain resource.

[0072] The synchronization signal and physical broadcast channel corresponding to the first shared time domain resource, and the synchronization signal and / or physical broadcast channel corresponding to the second shared time domain resource are transmitted in the same bandwidth portion, or in different bandwidth portions;

[0073] This embodiment does not impose specific restrictions on the method of network access.

[0074] In this embodiment, the synchronization signal and the physical broadcast channel are transmitted through different transmission methods. In some time slots, the physical broadcast channel or the synchronization channel can occupy time domain resources for transmission independently, which solves the problem of resource waste in network power consumption caused by the limitation of joint transmission of synchronization signal and physical broadcast channel.

[0075] In one embodiment, the synchronization signal includes a primary synchronization signal and a secondary synchronization signal. Accordingly, the synchronization signal and the physical broadcast channel share time domain resources for transmission in the first time slot, while the synchronization signal or the physical broadcast channel alone occupies time domain resources for transmission in the second time slot, including one of the following methods:

[0076] In the first time slot, the main synchronization signal, the auxiliary synchronization signal, and the physical broadcast channel share time domain resources for transmission, while in the second time slot, either the main synchronization signal or the auxiliary synchronization signal occupies time domain resources for transmission alone.

[0077] In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission; in the second time slot, the primary synchronization signal and the secondary synchronization signal share time domain resources for transmission.

[0078] In the first time slot, the auxiliary synchronization signal and the physical broadcast channel share time domain resources for transmission, while in the second time slot, the auxiliary synchronization signal and the main synchronization signal share time domain resources for transmission.

[0079] In the first time slot, the synchronization signal and the physical broadcast channel share the time domain resources for transmission. In the second time slot, the synchronization signal occupies the time domain resources for transmission alone. In the third time slot, the physical broadcast channel occupies the time domain resources for transmission alone.

[0080] In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission. In the second time slot, either the primary synchronization signal or the secondary synchronization signal occupies time domain resources for transmission. In the third time slot, the secondary synchronization signal and the primary synchronization signal share time domain resources for transmission.

[0081] In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission. In the second time slot, the secondary synchronization signal occupies time domain resources for transmission alone. In the third time slot, the primary synchronization signal occupies time domain resources for transmission alone.

[0082] In the first time slot, the main synchronization signal, the auxiliary synchronization signal, and the physical broadcast channel share time domain resources for transmission. In the second time slot, either the main synchronization signal or the auxiliary synchronization signal occupies time domain resources for transmission. In the third time slot, the auxiliary synchronization signal and the physical broadcast channel share time domain resources for transmission.

[0083] In the first time slot, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel share time domain resources for transmission. In the second time slot, the secondary synchronization signal and the primary synchronization signal share time domain resources for transmission. In the third time slot, the secondary synchronization signal and the physical broadcast channel share time domain resources for transmission.

[0084] In one embodiment, the synchronization signal and the physical broadcast channel are transmitted periodically.

[0085] The synchronization signals include the primary synchronization signal PSS and the secondary synchronization signal SSS.

[0086] In this embodiment, the periods of the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel can be the same or different; there are multiple options for the periods of the synchronization signal, the secondary synchronization signal, and the physical broadcast channel; the periods of the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel can be configured in the System Information Block (SIB).

[0087] In one embodiment, the transmission period of the synchronization signal and the transmission period of the physical broadcast channel have at least one of the following relationships:

[0088] The transmission period of the physical broadcast channel is greater than or equal to the transmission period of the synchronization signal;

[0089] The transmission period of the physical broadcast channel is longer than that of the secondary synchronization signal, and the transmission period of the secondary synchronization signal is longer than that of the primary synchronization signal.

[0090] The transmission period of the physical broadcast channel is the same as that of the auxiliary synchronization signal, while the transmission period of the primary synchronization signal is longer than that of the physical broadcast channel.

[0091] The transmission period of the physical broadcast channel is the same as that of the synchronization signal.

[0092] In this embodiment, the transmission period of the physical broadcast channel can be greater than or equal to the transmission period of the synchronization signal. For example, the PBCH period is 4, 8, or 16 times the synchronization signal period. The transmission period of the physical broadcast channel can be freely selected. For example, the PBCH transmission period can be 10ms, 20ms, 40ms, 80ms, 160ms, 320ms, 640ms, etc. The synchronization signal period can have multiple selections, such as 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, 320ms, etc.

[0093] Specific settings include: PBCH period of 20ms and synchronization signal (PSS / SSS) period of 5ms; or PBCH period of 40ms and synchronization signal (PSS / SSS) period of 10ms; or PBCH period of 80ms and synchronization signal (PSS / SSS) period of 20ms; or PBCH period of 160ms or 320ms and synchronization signal (PSS / SSS) period of 20ms, etc.

[0094] When the physical broadcast channel is transmitted, the physical broadcast channel and the synchronization signal are transmitted on consecutive time-domain symbols, or there is a predefined time-domain symbol interval between the PBCH and the synchronization signal. The transmission period of the physical broadcast channel and the transmission period of the secondary synchronization signal can be configured in the SIB. Multiple synchronization signals are associated with a physical broadcast channel, and these associated PSS, SSS, and PBCH have the same beam index. Figure 3 This is a schematic diagram illustrating the first association relationship between the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel, provided in an embodiment of this application.

[0095] In this embodiment, the transmission periods of the Physical Broadcast Channel (PBCH), the primary synchronization signal, and the secondary synchronization signal are different. The transmission period of PBCH is longer than that of SSS, and the transmission period of SSS is longer than that of PSS. For example, the transmission period of PSS is 5ms, the transmission period of SSS is 10ms, and the transmission period of PBCH is 20ms; or, the transmission period of PSS is 5ms, the transmission period of SSS is 20ms, and the transmission period of PBCH is 40ms; or, the transmission period of PSS is 10ms, the transmission period of SSS is 20ms, and the transmission period of PBCH is 40ms; or, the transmission period of PSS is 10ms, the transmission period of SSS is 40ms, and the transmission period of PBC is 160ms or 320ms; or, the transmission period of PSS is 10ms, the transmission period of SSS is 20ms, and the transmission period of PBCH is 160ms or 320ms. The transmission period of PBCH can be selected in various ways, such as 10ms, 20ms, 40ms, 80ms, 160ms, 320ms, etc.; the transmission period of PSS can be selected in various ways, such as 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, 320ms, etc.; the transmission period of SSS can be selected in various ways, such as 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, 320ms, etc.

[0096] When the physical broadcast channel is transmitted, the physical broadcast channel and the synchronization signal are transmitted on consecutive time-domain symbols, or there is a predefined time-domain symbol interval between the physical broadcast channel and the synchronization signal. The period of the physical broadcast channel and the period of the secondary synchronization signal can be configured in the SIB; multiple primary synchronization signals are associated with one secondary synchronization signal, and multiple secondary synchronization signals are associated with one physical broadcast channel. These associated physical broadcast channels, primary synchronization signals, and secondary synchronization signals correspond to the same beam index. When the physical broadcast channel is transmitted, the physical broadcast channel, primary synchronization signal, and secondary synchronization signal are transmitted on adjacent time-domain symbols, or there is a predefined time-domain symbol interval between the physical broadcast channel, primary synchronization signal, and secondary synchronization signal; when the secondary synchronization signal is transmitted, the secondary synchronization signal and the primary synchronization signal are transmitted on consecutive time-domain symbols, or there is a predefined time-domain symbol interval between the secondary synchronization signal and the primary synchronization signal. Figure 4 This is a schematic diagram illustrating the second correlation between the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel, provided in an embodiment of this application.

[0097] In this embodiment, the physical broadcast channel and the secondary synchronization signal have the same transmission period, while the transmission period of the primary synchronization signal is longer than that of the physical broadcast channel. For example, the transmission period of the PSS is 5ms, the transmission period of the SSS is 10ms or 20ms, and the transmission period of the PBCH is 10ms or 20ms; or, the transmission period of the PSS is 10ms, the transmission period of the SSS is 40ms, and the transmission period of the PBCH is 40ms; or, the transmission period of the PSS is 20ms, the transmission period of the SSS is 80ms, and the transmission period of the PBCH is 80ms. The transmission periods of the PBCH and SSS can be selected from various values, such as 10ms, 20ms, 40ms, 80ms, 160ms, and 320ms; the transmission period of the PSS can also be selected from various values, such as 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, and 320ms.

[0098] The transmission periods of the physical broadcast channel, secondary synchronization signal, and primary synchronization signal can be configured in the SIB. Multiple primary synchronization signals can be associated with a secondary synchronization signal or physical broadcast channel, and these associated physical broadcast channels, secondary synchronization signals, and primary synchronization signals have the same beam index. The physical broadcast channel and secondary synchronization signal can be transmitted on consecutive time-domain symbols, or the primary synchronization signal and secondary synchronization signal can be transmitted on discontinuous time-domain symbols with a predefined time-domain symbol interval; the physical broadcast channel, primary synchronization signal, and secondary synchronization signal can be transmitted on adjacent time-domain symbols, or there can be a predetermined time-domain symbol interval between the broadcast channel, primary synchronization signal, and secondary synchronization signal. Figure 5 This is a schematic diagram illustrating the third relationship between the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel, provided in an embodiment of this application.

[0099] In this embodiment, the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel have the same transmission period. The secondary synchronization signal and the physical broadcast channel are located on consecutive time domain symbols. The time domains of the secondary synchronization signal and the physical broadcast channel may overlap or not overlap. The primary synchronization signal and the secondary synchronization signal or the physical broadcast channel are located in different time slots. Figure 6 This is a schematic diagram illustrating the fourth correlation between the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel, provided in an embodiment of this application.

[0100] In carrier aggregation scenarios, some carriers may transmit only the secondary synchronization signal, while others may transmit the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel. Alternatively, some carriers may transmit only the primary synchronization signal and the secondary synchronization signal, while others may transmit the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel.

[0101] The transmission method in this embodiment breaks the bonded transmission relationship between the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel, allowing the transmission period of the physical broadcast channel to be longer than that of the primary and secondary synchronization signals, and the transmission period can be freely selected, thus achieving network energy saving.

[0102] In one embodiment, the presence of signal and / or channel transmission is determined by at least one of the following methods:

[0103] The presence of synchronization signals and physical broadcast channels is determined through blind detection.

[0104] The presence of a physical broadcast channel is indicated by the primary synchronization signal and / or secondary synchronization signal.

[0105] In this embodiment, when the primary synchronization signal, secondary synchronization signal, and physical broadcast channel have different periods, one approach is for the terminal to determine whether there is a primary synchronization signal, secondary synchronization signal, and physical broadcast channel through blind detection. Another approach is to use the primary synchronization signal and / or secondary synchronization signal to indicate whether there is a physical broadcast channel transmission.

[0106] In one embodiment, the presence of a physical broadcast channel is determined according to one or more of the following methods:

[0107] The presence of a physical broadcast channel is determined by the number of time-domain intervals between the primary synchronization signal and the secondary synchronization signal.

[0108] The order of the primary synchronization signal and the secondary synchronization signal determines whether there is a physical broadcast channel for transmission;

[0109] The sequence number of the auxiliary synchronization signal determines whether there is a physical broadcast channel for transmission.

[0110] In this embodiment, the presence of PBCH transmission is determined by the number of time-domain intervals between PSS and SSS. For example, when the number of time-domain intervals between PSS and SSS is 0, there is no PBCH transmission; when the number of time-domain intervals between PSS and SSS is not 0, there is PBCH transmission. Alternatively, when the number of time-domain intervals between PSS and SSS is 0, there is PBCH transmission; when the number of time-domain intervals between PSS and SSS is not 0, there is no PBCH transmission. Alternatively, when the time-domain interval data between PSS and SSS is t1, there is no PBCH transmission; when the time-domain interval data between PSS and SSS is t2, there is PBCH transmission, where t1 and t2 are not equal. Figure 7 This is a schematic diagram illustrating the fifth correlation between the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel, provided in an embodiment of this application.

[0111] In this embodiment, the presence or absence of PBCH transmission is determined by the order of PSS and SSS. For example, if PSS is transmitted before SSS, there is no PBCH transmission; if PSS is transmitted after SSS, there is PBCH transmission. Alternatively, if PSS is transmitted before SSS, there is PBCH transmission; if PSS is transmitted after SSS, there is no PBCH transmission.

[0112] In this embodiment, the presence of PBCH transmission is determined by the sequence of the SSS. For example, when the SSS uses sequence 1 for transmission, there is no PBCH transmission; when the SSS uses sequence 2, there is PBCH transmission. Sequence 1 and sequence 2 can correspond to different sequences of the same length, or a set of different sequences of the same length, or different sequences of different lengths, or a set of different sequences of different lengths.

[0113] In one embodiment, the presence of synchronization signals and physical broadcast channel transmission is determined according to one or more of the following methods:

[0114] The sequence number of the primary synchronization signal determines whether there is a secondary synchronization signal and / or physical broadcast channel transmission;

[0115] A proprietary indicator signal indicates whether there is a secondary synchronization signal and / or a primary synchronization signal and / or a physical broadcast channel transmission.

[0116] In this embodiment, the presence of SSS and / or PBCH transmission is determined by the sequence of the PSS. For example, when the PSS uses sequence 3 for transmission, there is no SSS and / or PBCH transmission; when the PSS uses sequence 4, there is SSS and / or PBCH transmission. Sequences 3 and 4 can correspond to different sequences of the same length, or a set of different sequences of the same length, or different sequences or sets of different sequences of different lengths.

[0117] In this embodiment, a proprietary indicator signal indicates whether PBCH and / or SSS, and / or PSS are being transmitted. For example, if the proprietary indicator signal is detected, PBCH and / or SSS, and / or PSS are being transmitted; if the proprietary indicator signal is not detected, PBCH and / or SSS, and / or PSS are not being transmitted. The proprietary indicator signal is transmitted in an OOK manner, corresponding to a specific sequence of 0s and 1s with a fixed length. Alternatively, the proprietary indicator signal can be enabled or disabled by the SIB, along with its frequency domain position and / or sequence information. Figure 8 This is a schematic diagram of the indication signal transmission provided in an embodiment of this application.

[0118] Among them, the proprietary indication signal can be located in Figure 8Before the middle time window, or at the beginning of the time window, the time window period and time domain position are configured by SIB. A proprietary indication signal is used to indicate the transmission status of the physical broadcast channel and / or synchronization signal within the time window; indication information is carried by the sequence corresponding to the proprietary indication signal, and / or, indication information is carried by the presence of the proprietary indication signal.

[0119] The proprietary indicator signal can be a synchronization signal or a signal generated by other sequences.

[0120] In one embodiment, the determination of the number of time-domain symbols occupied by the physical broadcast channel includes at least one of the following:

[0121] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the length of the cyclic prefix corresponding to the physical broadcast channel;

[0122] The number of time-domain symbols occupied by the physical broadcast channel is determined according to the type of the cyclic prefix corresponding to the physical broadcast channel;

[0123] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the frequency point of the physical broadcast channel;

[0124] The number of time-domain symbols occupied by the physical broadcast channel is a fixed value;

[0125] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the subcarrier spacing;

[0126] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the frequency-domain bandwidth;

[0127] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the synchronization signal;

[0128] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the indication information;

[0129] The number of time-domain symbols occupied by the physical broadcast channel is determined based on whether the physical broadcast channel and the synchronization signal are transmitted separately in a time slot.

[0130] Among them, one subcarrier spacing corresponds to one time-domain symbol; one frequency-domain bandwidth corresponds to one time-domain symbol; one cyclic prefix size corresponds to one time-domain symbol; one cyclic prefix type corresponds to one time-domain symbol; and one frequency point corresponds to one time-domain symbol.

[0131] In this embodiment, when the PBCH uses fixed time-domain symbol transmission, the preferred number of time-domain symbols is 2, 3, 4, 6, or 7.

[0132] In this embodiment, multiple subcarrier spacing sets can be predefined, each subcarrier spacing set including one or more subcarriers. The number of time-domain symbols corresponding to each subcarrier spacing set is predefined. For example, when the subcarrier spacing is 15KHz, 30KHz, and 60KHz, the number of time-domain symbols is 3; when the subcarrier spacing is 120KHz, 240KHz, and 480KHz, the number of time-domain symbols is 6; when the subcarrier spacing is 15KHz and 30KHz, the number of time-domain symbols is 4; when the subcarrier spacing is 60KHz and 120KHz, the number of time-domain symbols is 6; and when the subcarrier spacing is 240KHz and 480KHz, the number of time-domain symbols is 8.

[0133] In this embodiment, multiple PBCH bandwidth sets can be predefined, each PBCH bandwidth set including one or more bandwidths. The number of time-domain symbols corresponding to each bandwidth set is predefined. For example, when the PBCH bandwidth is 240 subcarriers, the number of time-domain symbols is 3; when the PBCH bandwidth is 120 subcarriers, the number of time-domain symbols is 6; when the PBCH bandwidth is less than or equal to a preset value, the number of time-domain symbols is 4; and when the PBCH bandwidth is greater than the preset value, the number of time-domain symbols is 8.

[0134] In this embodiment, the number of time-domain symbols occupied by the PBCH can also be determined based on the synchronization signal. There is no limitation on which information from the synchronization signal is used to determine the number of time-domain symbols occupied by the PBCH. The number of time-domain symbols occupied by the physical broadcast channel can also be determined based on whether the PBCH and the synchronization signal are transmitted separately in a single time slot. The number of time-domain symbols occupied when the PBCH is transmitted together with other signals in a single time slot is different from the number of time-domain symbols occupied when the PBCH is transmitted separately in a single time slot.

[0135] In this embodiment, the number of time-domain symbols occupied by the PBCH can also be determined through proprietary indication information. This indication information can be used to indicate the number of time-domain symbols for data in the PBCH. In one embodiment, the indication information includes at least one of the following:

[0136] The number of time-domain symbols in the data; the size of the information carried by the data; the type of information carried by the data.

[0137] In this embodiment, Figure 9 This is a schematic diagram of the structure of a physical broadcast channel provided in an embodiment of this application, as shown below. Figure 9As shown, when the PBCH is transmitted using a preamble + control + data structure, the data corresponds to the information carried by the PBCH, and the control corresponds to the indication information of the data. The indication information may include at least one of the following: the number of time-domain symbols of the data, the size of the carried information, and the type of the carried information. Alternatively, when the PBCH is transmitted using a preamble + data structure, the data corresponds to the information carried by the PBCH, and the preamble carries the indication information of the data. The indication information may include at least one of the following: the number of time-domain symbols of the data, the size of the carried information, and the type of the carried information.

[0138] In one embodiment, the method for determining the number of time-domain symbols occupied by the physical broadcast channel based on the synchronization signal includes:

[0139] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the number of time-domain symbols of the primary synchronization signal and / or the secondary synchronization signal.

[0140] The number of time-domain symbols occupied by the physical broadcast channel is determined based on the sequence length of the primary synchronization signal and / or secondary synchronization signal.

[0141] In this embodiment, the number of time-domain symbols of the PBCH can be determined based on the number of time-domain symbols of the primary synchronization signal and / or the secondary synchronization signal, or based on the sequence length of the primary synchronization signal and / or the secondary synchronization signal. For example: when the number of time-domain symbols of the PSS and / or SSS is m1, the PBCH occupies n1 time-domain symbols; when the number of time-domain symbols of the PSS and / or SSS is m2, the PBCH occupies n2 time-domain symbols; when the sequence length of the PSS and / or SSS is t1, the PBCH occupies n1 time-domain symbols; when the sequence length of the PSS and / or SSS is t2, the PBCH occupies n2 time-domain symbols.

[0142] In one embodiment, when the physical broadcast channel and the synchronization signal are transmitted together in one time slot, the number of time-domain symbols occupied by the physical broadcast channel is a first value; when the physical broadcast channel is transmitted alone in one time slot, the number of time-domain symbols occupied by the physical broadcast channel is a second value; wherein the first value and the second value are different values.

[0143] In one embodiment, the number of time-domain symbols occupied by the PBCH can be determined by the length or type of the cyclic prefix. For example, the number of time-domain symbols occupied by the PBCH corresponding to the first cyclic prefix length or the first cyclic prefix type is a first value, and the number of time-domain symbols occupied by the PBCH corresponding to the second cyclic prefix length or the second cyclic prefix type is a second value.

[0144] In one embodiment, the number of time-domain symbols occupied by the PBCH can be determined by the frequency point where the PBCH is located. For example, the number of time-domain symbols occupied by the PBCH corresponding to the first frequency point set (e.g., FR1 and FR2) is a first value, and the number of time-domain symbols occupied by the PBCH corresponding to the second frequency point set (e.g., FR3) is a second value.

[0145] In one embodiment, the number of subcarriers corresponding to the physical broadcast channel is determined in one of the following ways:

[0146] The number of subcarriers corresponding to the physical broadcast channel is a fixed value;

[0147] The number of subcarriers corresponding to the physical broadcast channel is determined based on the number of time-domain symbols occupied by the physical broadcast channel.

[0148] In this embodiment, one approach is to use 96, 144, 192, 288, or 336 subcarriers when the number of subcarriers corresponding to the PBCH is a fixed value. Another approach is to determine the number of subcarriers corresponding to the PBCH based on the number of time-domain symbols occupied by the PBCH. When selecting the number of subcarriers using either of these approaches, it is ensured that the number of subcarriers occupied by the PBCH is an integer multiple of the number of subcarriers included in a resource block. When there are multiple numbers of time-domain symbols, the total number of resource units with different numbers of time-domain symbols should be kept to be the same or similar as much as possible.

[0149] In one embodiment, a physical broadcast channel is triggered by a trigger signal for periodic transmission.

[0150] One trigger signal can trigger one or more PBCHs to be sent in a cycle. The trigger signal can be a sequence or a 2ASK signal. The position of the trigger signal can be configured by SIB or by a predefined configuration.

[0151] In one embodiment, on the first time domain resource, the synchronization signal and the physical broadcast channel share continuous time domain symbols for transmission, and on the second time domain resource, the synchronization signal and the physical broadcast channel each separately occupy continuous time domain symbols for transmission; or, on the first time domain resource, the synchronization signal and the physical broadcast channel share continuous time domain symbols for transmission, and on the second time domain resource, the synchronization signal occupies continuous time domain symbols for transmission alone; or, on the first time domain resource, the synchronization signal and the physical broadcast channel share continuous time domain symbols for transmission, and on the second time domain resource, the synchronization signal uses discontinuous time domain symbols for transmission alone.

[0152] Figure 10 This is a schematic diagram illustrating the transmission of a physical broadcast channel and synchronization signal in the time domain symbols according to an embodiment of this application, as shown below. Figure 10As shown in styles 3 and 4, when PSS and SSS are transmitted on consecutive time-domain symbols, PBCH is also transmitted on consecutive time-domain symbols.

[0153] In one embodiment, the synchronization signal includes a primary synchronization signal and a secondary synchronization signal. When the primary synchronization signal and the secondary synchronization signal are transmitted on discontinuous time-domain symbols, the mapping method of the physical broadcast channel includes at least one of the following:

[0154] The time-domain symbol of the physical broadcast channel and the time-domain symbol of the auxiliary synchronization signal are adjacent, and the physical broadcast channel is located before or after the auxiliary synchronization signal, and their time domains do not overlap.

[0155] The time-domain symbol of the physical broadcast channel is adjacent to the time-domain symbol of the main synchronization signal, and the physical broadcast channel is located before or after the main synchronization signal, with no overlap in time domain.

[0156] When the interval between the primary synchronization signal and the secondary synchronization signal is 1 time-domain symbol, and the primary synchronization signal is located before the secondary synchronization signal, and the synchronization signal and the physical broadcast channel are located in the same time-domain resource, the secondary synchronization signal is located at the first preset position.

[0157] When the interval between the primary synchronization signal and the secondary synchronization signal is one time-domain symbol, and the secondary synchronization signal is located before the primary synchronization signal, and the synchronization signal and the physical broadcast channel are located in a common time-domain resource, the secondary synchronization signal is located at a second preset position, or the physical broadcast channel is located at the second-to-last time-domain symbol in the common time-domain resource, or the primary synchronization signal is located at a third preset position.

[0158] When the interval between the primary synchronization signal and the secondary synchronization signal is greater than or equal to 2 time-domain symbols, and the primary synchronization signal is located before the secondary synchronization signal, the secondary synchronization signal is located at the fourth preset position.

[0159] When the interval between the main synchronization signal and the auxiliary synchronization signal is greater than or equal to 2 time-domain symbols, and the auxiliary synchronization signal is located before the main synchronization signal, the auxiliary synchronization signal is located at the fifth preset position or the main synchronization signal is located at the sixth preset position.

[0160] When the interval between the primary synchronization signal and the secondary synchronization signal is a preset number of time-domain symbols, the physical broadcast channel is located between the primary synchronization signal and the secondary synchronization signal. The number of time-domain symbols occupied by the physical broadcast channel is the preset number, which is greater than 2. Specifically, the primary synchronization signal is located in the last time-domain symbol of the time-domain symbols occupied by the physical broadcast channel, and the secondary synchronization signal is located in the first time-domain symbol of the time-domain symbols occupied by the physical broadcast channel; or, the primary synchronization signal is located in the first time-domain symbol of the time-domain symbols occupied by the physical broadcast channel, and the secondary synchronization signal is located in the last time-domain symbol of the time-domain symbols occupied by the physical broadcast channel; or, the primary synchronization signal is located in the first time-domain symbol of the time-domain symbols occupied by the physical broadcast channel, and the secondary synchronization signal is located in the third or fourth time-domain symbol of the time-domain symbols occupied by the physical broadcast channel.

[0161] In one embodiment, the first preset position includes the first or second time domain symbol among the time domain symbols occupied by the physical broadcast channel;

[0162] The second preset position includes the last time domain symbol or the second-to-last time domain symbol in the time domain symbols occupied by the physical broadcast channel;

[0163] The third preset position includes the first or second time domain symbol in the time domain symbols occupied by the physical broadcast channel;

[0164] The fourth preset position includes the first or third time domain symbol in the time domain symbols occupied by the physical broadcast channel;

[0165] The fifth preset position includes the last time domain symbol or the third-to-last time domain symbol in the time domain symbols occupied by the physical broadcast channel.

[0166] The sixth preset position includes the first, second, or third time domain symbol among the time domain symbols occupied by the physical broadcast channel.

[0167] In this embodiment, when PSS and SSS are transmitted on discontinuous time-domain symbols, the PBCH mapping method can adopt at least one of the following:

[0168] The PBCH time domain symbol and the SSS time domain symbol are adjacent, with the PBCH either preceding or following the SSS, and the time domains do not overlap.

[0169] The PBCH time domain symbol and the PSS time domain symbol are adjacent, with the PBCH either preceding or following the PSS, and the time domains do not overlap.

[0170] When the interval between PSS and SSS is one time-domain symbol, and PSS precedes SSS, and PSS, SSS, and PBCH are located on a common time-domain resource, SSS is located on the first time-domain symbol in the time-domain symbol occupied by PBCH, such as... Figure 10 Style 2 in the text, or, SSS is located on the second time domain symbol in the time domain symbol occupied by PBCH, such as Figure 10 Style 1 in the text;

[0171] When the PSS and SSS are separated by one time domain symbol, and the SSS is located before the PSS, and the PSS, SSS, and PBCH are located in a common time domain resource, the SSS is located on the last time domain symbol occupied by the PBCH, or the PBCH is located on the second to last time domain symbol in the common time domain resource; or the PSS is located on the first time domain symbol occupied by the PBCH, or the PSS is located on the second time domain symbol occupied by the PBCH.

[0172] When the interval between PSS and SSS is 2 or more time domain symbols, and PSS is located before SSS, SSS is located on the first time domain symbol occupied by PBCH, or SSS is located on the third time domain symbol occupied by PBCH.

[0173] When the interval between PSS and SSS is 2 or more time domain symbols, and SSS is located before PSS, SSS is located on the last time domain symbol occupied by PBCH, or on the third to last time domain symbol occupied by PBCH.

[0174] When the interval between PSS and SSS is 3 or 4 time-domain symbols, PBCH is located between PSS and SSS, and the number of time-domain symbols in PBCH is 3 or 4.

[0175] The PSS is located on the first time domain symbol occupied by the PBCH, and the SSS is located on the last time domain symbol occupied by the PBCH. Alternatively, the SSS is located on the first time domain symbol occupied by the PBCH, and the PSS is located on the last time domain symbol occupied by the PBCH. The number of time domain symbols occupied by the PBCH can be 3, 4, 5, 6, etc.

[0176] In one embodiment, the physical broadcast channel is transmitted using a prefix part + data part structure. The prefix part and the data part are transmitted using amplitude shift keying (APS) or orthogonal frequency division multiplexing (OFDM) symbols. Alternatively, the prefix part is transmitted using APS and the data part is transmitted using OFDM symbols.

[0177] In this embodiment, in order to reduce network overhead and better save network energy, in 6G or future wireless systems, such as Figure 11 As shown, Figure 11 The following is a schematic diagram of another physical broadcast channel structure provided in an embodiment of this application. The PSS / SSS / PBCH functions can be implemented using a Preamble+data structure. The data part carries at least one of the following: PBCH-bearing information, cell identification information, and frame information. Whether data is transmitted depends on whether there is Preamble transmission or the sequence corresponding to the Preamble. For example, when Preamble uses sequence 1, there is data transmission; when Preamble uses sequence 2, there is no data transmission. Alternatively, data may be transmitted or not transmitted when Preamble is sent. Preamble can be sent periodically or aperiodically.

[0178] Preamble can be transmitted using OOK (2ASK) or OFDM methods;

[0179] Data can be transmitted using OOK or OFDM methods;

[0180] Preferably, both the preamble and data are transmitted using the OOK method;

[0181] Preferably, the preamble is transmitted using OOK mode, and the data is transmitted using OFDM mode, with a predefined interval between the preamble and the data;

[0182] The terminal determines whether there is a preamble transmission through blind detection. After the preamble is detected, it then blindly detects the data to obtain the information carried by the data part, or determines whether there is a data transmission based on the sequence detected by the preamble.

[0183] In the above embodiments, Figure 12 This is a transmission diagram illustrating a physical broadcast channel, secondary synchronization signal, and primary synchronization signal provided in an embodiment of this application, as shown below. Figure 12As shown, PSS, SSS, and PBCH can be transmitted using OFDM, or PSS can be transmitted using OOK, and SSS and PBCH can be transmitted using OFDM. In this case, there is a predefined interval between PBCH or SSS and PSS. Alternatively, PSS and SSS can be transmitted using OOK, and PBCH can be transmitted using OFDM. In this case, there is also a predefined interval between PBCH and PSS or SSS. The aforementioned predefined interval is determined based on the terminal processing time, in units of time domain symbols, such as: 1 time domain symbol, or 2 time domain symbols, or 3 time domain symbols, or 4 time domain symbols, or one time slot.

[0184] In another approach, Preamble+data replaces PSS, while SSS and PBCH still exist. It is transmitted as described in the above embodiments. The information carried in the data portion may include at least one of the following: SSS configuration information, PBCH configuration information, access control information, frame information, and Physical Downlink Control Channel (PDCCH) configuration information. In yet another approach, Preamble+data replaces PSS and / or PBCH. SSS still exists and is transmitted as described in the above embodiments, but PBCH is not transmitted. The information carried in the data portion may include at least one of the following: SSS configuration information, PBCH configuration information, access control information, frame information, PDCCH configuration information, frequency domain location information, access information, and paging configuration.

[0185] The PDCCH configuration information corresponds to the PDCCH scheduling PDSCH transmission system information; the SSS configuration information includes at least one of the following: SSS period, time domain position, frequency domain position, presence of SSS, and time domain offset; the PDCCH configuration includes at least one of the following: PDCCH time domain position, PDCCH search space size, subcarrier spacing, and PDCCH frequency domain position; the access information includes access resource information initiated by the terminal, specifically including at least one of the following: access resource time domain information, access resource frequency domain information, and access resource sequence information; the paging configuration information includes wake-up terminal access network information and / or system message change indication. The access control information specifically includes: whether access is allowed.

[0186] The terminal obtains data bearer information through blind detection, performs PDCCH detection on the corresponding resources based on the PDCCH configuration information carried by the data bearer, decodes the PDSCH through the scheduling information carried by the detected PDCCH, obtains the system message carried by the PDSCH, initiates access based on the access information carried by the system message, completes the access process, and accesses the network; or, it performs data transmission based on the data transmission information carried by the system message; when the data bearer access information, the terminal directly initiates access after obtaining the data, detects the PDCCH according to the PDCCH configuration information, obtains the access response information and uplink data transmission information scheduling sent by the network to the terminal, and completes the access process. Figure 13 This is another transmission schematic diagram of the physical broadcast channel, secondary synchronization signal, and primary synchronization signal provided in an embodiment of this application, as shown below. Figure 13 As shown, the OOK signal is a preamble (single or multiple sequences) or preamble+data, used for coarse synchronization, or to indicate the existence of SSS, or to carry configuration information; the OOK signal can be used for at least one of coarse synchronization and cell discovery, SSS indication, and PBCH indication.

[0187] In one embodiment, the time domain length of the first shared time domain resource is different from the time domain length of the second shared time domain resource; or, the frequency domain width of the first shared time domain resource is different from the frequency domain width of the second shared time domain resource; or, the sequence of the primary synchronization signal or the sequence of the secondary synchronization signal on the first shared time domain resource is different from the sequence of the primary synchronization signal or the sequence of the secondary synchronization signal on the second shared time domain resource; or, the first shared time domain resource is the same as the time domain resource shared by the synchronization signal and physical broadcast of the 6G system, and the second shared time domain resource is the same as the time domain resource shared by the synchronization signal of the 5G system; or, the synchronization signal and physical broadcast signal in the first shared time domain resource are... The relative positional relationship of the channels is different from that of the synchronization signal and the physical broadcast channel in the second shared time domain resource; or, the subcarrier spacing of the first shared time domain resource is different from that of the second shared time domain resource; or, the cyclic prefix corresponding to the first shared time domain resource is different from that of the second shared time domain resource; or, the signaling carried by the physical broadcast channel corresponding to the first shared time domain resource is different from that carried by the physical broadcast channel corresponding to the second shared time domain resource; or, the number of information bits carried by the physical broadcast channel corresponding to the first shared time domain resource is different from that carried by the physical broadcast channel corresponding to the second shared time domain resource.

[0188] Specifically, the signaling carried by the physical broadcast channel corresponding to the first shared time domain resource includes at least one of the following: PDCCH configuration information, radio frame information, and frequency domain location information; the signaling carried by the physical broadcast channel corresponding to the second shared time domain resource includes access resource information and / or paging configuration information.

[0189] In one embodiment, when the synchronization signal and physical broadcast channel adopt the synchronization signal and physical broadcast channel structure of a 5G system, at least one of the pilot of the physical broadcast channel, the scrambling code sequence of cyclic redundancy check, and the reserved bits in the physical broadcast channel is used to indicate that the access network is a 6G network.

[0190] The reserved bits in the physical broadcast channel are the bits reserved in the 5G physical broadcast channel.

[0191] In this embodiment, the synchronization channel and physical broadcast channel of the 6G system have multiple structures. One structure is the same as the SSB structure of the 5G system, and the other structure is a completely new structure. For example, it is different from 5G in terms of time-frequency position relationship, or in terms of sequence, or in terms of the number of subcarriers, or in terms of the number of time domain symbols.

[0192] When the synchronization channel and physical broadcast channel of a 6G system adopt the SSB structure of a 5G system, the pilot and scrambling sequence of the PBCH (Plan-Based Switching) can be used; or, reserved bits in the PBCH can indicate that the current system is 6G; the reserved bits in the PBCH are the bits reserved in the 5G PBCH; in addition, if it is desired to allow some 5G terminals to access the network, the access prohibition command in the PBCH can be set to prohibit, the reserved bits can be set to a specific value, and other bits can be redefined to indicate new functions for use by 6G or 5G-A terminals.

[0193] When the synchronization channel and physical broadcast channel of a 6G system adopt a new structure, the terminal determines whether the current network is a 6G network by detecting the synchronization channel and / or physical broadcast channel through blind detection.

[0194] Figure 14 A flowchart of another channel transmission method provided in an embodiment of this application is shown below. Figure 14 As shown, the channel transmission method provided in this embodiment can be applied to a base station, including S210.

[0195] S210. Send a synchronization signal and a physical broadcast channel to the terminal so that the terminal can access the network based on the synchronization signal and / or the physical broadcast channel.

[0196] The transmission methods of the synchronization signal and the physical broadcast channel include:

[0197] In the first time slot, the synchronization signal and the physical broadcast channel share time domain resources for transmission, while in the second time slot, either the synchronization signal or the physical broadcast channel occupies time domain resources for transmission alone.

[0198] And / or,
