Alternatively, the wireless communication system 100 may include a plurality of network devices and may include other numbers of terminal devices within the coverage of each network device. The application embodiment does not limit this.

Optionally, the wireless communication system 100 may further include other network entities, such as a network controller, a mobility management entity, and the like.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" in this context is merely an association describing the associated object, indicating that there may be three relationships, for example, A and / or B, which may indicate that A exists separately, and A and B exist separately. There are three cases of B. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

In this embodiment, the network device may send a synchronization signal block to the terminal device, and each synchronization signal block may include a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a physical broadcast channel. (Physical Broadcasting Channel, PBCH).

Optionally, the network device may separately send at least one synchronization signal block at each of the at least one frequency point.

For example, for a broadband component carrier with a bandwidth of 400 MHz or even 1 GHz, on the terminal side, terminal devices with multiple working bandwidths are distributed in the same system broadband component carrier due to different usage scenarios and different cost considerations. For example, if the system bandwidth is 400 MHz, terminal devices with a bandwidth of 400 MHz may be distributed, and terminal devices with a bandwidth of 100 MHz, 40 MHz, and 10 MHz may also be available. Thus, if there is only one Synchronization Signal Block (SSB) location within the system broadband component carrier, the terminal device with a smaller working bandwidth may not have an SS block within its working bandwidth. Therefore, when the terminal device needs to receive the SS block for time-frequency synchronization, RRM measurement, and reading the PBCH, it needs to be frequency-modulated to the frequency position where the SS block is located. On the other hand, for broadband component carriers with very large bandwidths, the propagation characteristics of different frequency locations may vary greatly. For example, there are large differences in the path loss between the high frequency band and the low frequency band of the broadband component carrier.

Therefore, the network device can separately transmit the synchronization signal block at a plurality of frequency points.

Optionally, when multiple synchronization signal blocks are transmitted at a certain frequency point, different synchronization signal blocks may be transmitted by using different beams.

Optionally, the PBCH included in the synchronization signal block may indicate an RMSI corresponding to the synchronization signal block, where the RMSI may include a physical random access channel required for performing a random access procedure when accessing the synchronization signal block. (Physical Random Access Channel, PRACH) configuration information of a resource and/or a random access preamble set. The RMSI corresponding to the synchronization signal block may also carry other information, which is not specifically limited in this embodiment of the present application.

Optionally, when the SSBs are transmitted on multiple frequency points, the SSB and the RMSI may have a many-to-one relationship, that is, the SSBs at multiple frequency points correspond to the same RMSI.

Since the network device can send the synchronization signal block to the terminal device at the at least one frequency point, the terminal device can search for the SS block within the system bandwidth to obtain the cell identifier (Identifier, ID), time and frequency. Steps: Obtain PBCH information, and perform Radio Resource Management (RRM) measurement based on SSS and PBCH Demodulation Reference Signal (DMRS).

After the network device knows the frequency point of the synchronization signal block searched or detected by the terminal device, the synchronization signal block may be determined as the synchronization signal block of the defined cell of the terminal device. And further, based on the synchronization signal block of the defined cell, the frequency domain reference point, the resource allocation, the bandwidth part configuration or the scheduling performed on the terminal device may be determined.

The following describes how to make the network device know the frequency of the sync signal block detected by the terminal device.

Optionally, the terminal device sends the first frequency point information to the network device by using a message 3 (MSG3) or a radio resource control (RRC) signaling in a random access procedure.

Optionally, the first frequency point information is carried in: RRC signaling (eg, RRC Connection Request) in the MSG3 in the random access procedure, or media access control in the MSG3 (Media Access Control, MAC) in the Control Element (CE); or,

In 230, the network device receives the first frequency point information of the first synchronization signal block sent by the terminal device.

In 240, the network device determines a frequency point of the first synchronization signal block according to the first frequency point information.

Optionally, in the embodiment of the present application, the first frequency point information includes a frequency value of a frequency point of the first synchronization signal block.

Specifically, when the terminal device detects the first synchronization signal block, the first synchronization signal may be used. The frequency value of the absolute frequency of the block is informed to the network device, so that the network device can directly obtain the frequency of the first synchronization signal block according to the reporting of the terminal device.

Optionally, the first frequency point information is used to indicate a first frequency domain offset between a frequency point of the first synchronization signal block and a frequency point of the corresponding RMSI.

Correspondingly, after receiving the first frequency point information, the network device may obtain a frequency domain offset between a frequency point of the first synchronization signal block and a frequency point of the corresponding RMSI, because the frequency of the RMSI is for the network device. It may be known that the network device can thereby know the frequency of the first synchronization signal block.

Optionally, the network device may determine the frequency of the RMSI by receiving a PRACH signal sent by the terminal device (for example, message 1 (MSG1) in the random access procedure to obtain an RMSI for configuring the PRACH resource.

Optionally, the frequency of the SSB may be any one of the frequency points occupied by the SSB, for example, may be the center frequency of the SSB, or the frequency or maximum corresponding to the smallest physical resource block (PRB). The PRB corresponds to the frequency point and so on.

Optionally, the frequency of the RMSI may be any of the frequency points of the RMSI control resource set (eg, Control Resource Set, CORESET), for example, the center frequency of the RMSI CORESET; or the frequency corresponding to the RMSI CORESET minimum PRB. Point or RMSI CORESET maximum PRB corresponding frequency point, etc.

Optionally, the frequency of the RMSI may be any one of the frequency points of the RMSI Physical Downlink Shared Channel (PDSCH), for example, the center frequency of the RMSI PDSCH, or the frequency corresponding to the RMSI PDSCH minimum PRB. Point, or the frequency point corresponding to the largest PRB of the RMSI PDSCH.

Optionally, the first frequency domain offset may be a frequency domain offset of the frequency point of the RMSI relative to a frequency point of the first synchronization signal block. In this case, the reference point for obtaining the first frequency domain offset may be The frequency of the first sync signal block.

For example, as shown in FIG. 3, the frequency domain offset of the RMSI relative to the SSB frequency point 1 is the frequency domain offset 1, and the frequency domain offset of the RMSI relative to the SSB frequency point 2 is the frequency domain offset 2, The frequency domain offset of the RMSI relative to the SSB frequency point 3 is the frequency domain offset 3, and the frequency domain offset of the RMSI relative to the SSB frequency point 4 is the frequency domain offset 4.

Similarly, the first frequency domain offset may be a frequency domain offset of a frequency point of the first synchronization signal block relative to a corresponding RMSI frequency. In this case, the reference point for obtaining the first frequency domain offset may be The frequency of RMSI.

Optionally, the PBCH in the first synchronization signal block carries second frequency point information, where the second frequency point information is used to indicate a second between the frequency point of the first synchronization signal block and the frequency point of the RMSI Frequency domain offset; the terminal device may determine the first frequency point information based on the second frequency point information.

Optionally, the second frequency point information is used to indicate: a second frequency domain offset between a frequency point of the first synchronization signal block and a frequency point of the RMSI.

The second frequency domain offset may be a frequency domain offset of the frequency point of the first synchronization signal block relative to the frequency of the RMSI. In this case, the reference point for obtaining the second frequency domain offset may be the RMSI. Frequency point.

Alternatively, the second frequency domain offset may be an offset of a frequency point of the RMSI with respect to a frequency point of the first synchronization signal block. In this case, the reference point for obtaining the second frequency domain offset may be the first synchronization. The reference point of the signal block.

Specifically, after selecting the frequency point of the RMSI, the network device may search for a corresponding frequency offset (ie, a frequency domain offset) corresponding to the number of the indication bit in the PBCH, and carry it in the PBCH. For example, as shown in Table 1 below.

Table 1

Optionally, the relative frequency positional relationship between the frequency points when the first frequency domain offset is obtained is the same as the relative frequency positional relationship between the frequency points when the second frequency domain offset is obtained.

For example, the first frequency domain offset is a frequency domain offset of a frequency point of the synchronization signal block relative to the frequency point of the RMSI, and the second frequency domain offset is a frequency point of the synchronization signal block relative to a frequency point of the RMSI. a frequency domain offset; or the first frequency domain offset may be an offset of a frequency point of the RMSI relative to a frequency point of the synchronization signal block, and the second frequency domain offset may be a frequency point of the RMSI relative to the synchronization The offset of the frequency of the signal block.

Optionally, the relative frequency positional relationship between the frequency points when the first frequency domain offset is obtained is different from the relative frequency positional relationship between the frequency points when the second frequency domain offset is obtained.

For example, the first frequency domain offset is a frequency domain offset of a frequency point of the synchronization signal block relative to the frequency point of the RMSI, and the second frequency domain offset may be a frequency point of the RMSI relative to the synchronization signal block. Frequency Offset of the point; or, the first frequency domain offset may be an offset of a frequency point of the RMSI relative to a frequency point of the synchronization signal block, and the second frequency domain offset is a relative frequency of the synchronization signal block The frequency domain offset of the frequency of the RMSI.

Optionally, the first frequency point information may indicate the first frequency domain offset by carrying a frequency value of the first frequency domain offset, or may carry a number value corresponding to the frequency value of the first frequency domain offset to indicate The first frequency domain offset.

Optionally, the second frequency point information may indicate the second frequency domain offset by carrying a frequency value of the second frequency domain offset, or may carry a number value corresponding to the frequency value of the second frequency domain to indicate the first A frequency domain offset.

The first frequency point information and the second frequency point information have been separately introduced above. The following describes how to obtain the first frequency point information based on the second frequency point information.

In an implementation manner, when the first frequency point information indicates the first frequency domain offset, and the second frequency point information indicates the second frequency domain offset, the bit value of the first frequency point information is equal to the The bit value of the second frequency point information is taken.

For example, the first frequency point information and the second frequency point information respectively carry the value of the frequency domain offset, and the bit value of the first frequency point information and the bit value of the second frequency point information may be the same.

For example, the first frequency point information and the second frequency point information respectively carry the number value of the frequency domain offset, and the bit value of the first frequency point information and the bit value of the second frequency point information may be the same.

In this implementation manner, the relative frequency position relationship corresponding to the first frequency domain offset and the relative frequency position relationship corresponding to the second frequency domain offset may be the same. Of course, the relative frequency positional relationship corresponding to the first frequency domain offset and the relative frequency positional relationship corresponding to the second frequency domain offset may be opposite.

In an implementation manner, the terminal device determines the first frequency point information based on the number value included in the second frequency point information.

Optionally, the number value included in the second frequency point information may be determined as the number value included in the first frequency point information.

For example, as shown in FIG. 3 and FIG. 4, the frequency point information about the SSB frequency point 1 may be multiplexed with the frequency offset bit of the RMSI relative to the PBCH indicated by the PBCH in the SSB frequency point 1: 11; the frequency point of the SSB frequency point 2 The information may multiplex the frequency offset bits of the RMSI relative to the PBCH indicated by the PBCH in the SSB frequency point 2: 10; the frequency point information about the SSB frequency point 3 may multiplex the frequency of the RMSI relative to the PBCH indicated by the PBCH in the SSB frequency point 3. Offset bit: 01; the frequency point information about the SSB frequency point 4 can be multiplexed with the frequency of the RMSI indicated by the PBCH in the SSB frequency point 4 relative to the PBCH Rate offset bit: 00. Among them, the specific table can be as shown in Table 2 below.

Specifically, since the relative frequency positional relationship between the frequency domain offset in the first frequency point information and the frequency domain offset in the second frequency point information is different, the corresponding numbers may be different.

For example, the frequency domain offset corresponding to the first frequency point information is an offset of the frequency point of the synchronization signal block relative to the frequency point of the RMSI, and the frequency domain offset corresponding to the second frequency point information is the frequency point of the RMSI relative to the synchronization signal block. The offset of the frequency point.

For example, the frequency domain offset corresponding to the first frequency point information is an offset of the frequency point of the RMSI relative to the frequency point of the synchronization signal block, and the frequency domain offset corresponding to the second frequency point information is the frequency point relative to the RMSI of the synchronization signal block.

The frequency point of the sync signal block is obtained.

For example, the relationship between the plurality of number values and the frequency values of the plurality of frequency domain offsets may be as shown in Table 4, wherein the frequency offset in the first frequency point information may be the frequency point of the synchronization signal block relative to the PBCH. The frequency domain offset of the frequency point may also be the frequency domain offset of the frequency point of the PBCH relative to the frequency point of the synchronization signal block.
