Detailed Description

The following description of the technical solutions according to the embodiments of the present invention will be given with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.

Some terms referred to in this application will be briefly described as follows:

research on the next generation (New radio, NR) system currently mainly considers two Frequency bands, a Frequency band FR1 (Frequency range 1) and a Frequency band FR2 (Frequency range 2), wherein the Frequency domain ranges included in FR1 and FR2 are shown in table 1. It should be understood that the embodiments of the present application may be applied to FR1 and FR2 frequency bands, and may also be applied to other frequency bands, for example, a frequency band of 52.6GHz to 71GHz, or a frequency band of 71GHz to 100GHz, etc., which is not limited in this application.

Frequency band definition	Corresponding frequency range
FR1	410MHz–7.125GHz
FR2	24.25GHz–52.6GHz

TABLE 1

Studies of NR systems include non-terrestrial communication network equipment (Non Terrestrial Network, NTN) technology, where NTN typically provides communication services to terrestrial users by way of satellite communications. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit, geosynchronous Orbit) satellites, HEO (High Elliptical Orbit ) satellites, and the like according to the difference in Orbit heights. LEO and GEO are the main studies at the present stage.

For LEO satellites, the orbital heights range from 500km to 1500km, with corresponding orbital periods of about 1.5 hours to 2 hours. The signal propagation delay for single hop communications between terminals is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the terminal is not high.

For GEO satellites, the orbital altitude is 35786km and the period of rotation around the earth is 24 hours. The signal propagation delay for single hop communications between users is typically 250ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

Initial access in the NR system is accomplished by a synchronization signal Block (Synchronizing Signal/PBCH Block, SSB or SS/PBCH Block). SSB includes a primary synchronization signal (Primary synchronization signal, PSS), a secondary synchronization signal (Secondary synchronization signal, SSS), and a physical broadcast channel (Physical Broadcast Channel, PBCH).

In the NR system, the sync signal block SSB pattern supported by FR1 includes 3 cases (Case a, case B, case C), and the SSB pattern supported by FR2 includes 2 cases (Case D, case E). Wherein one SSB transmission opportunity may include one or more SSBs, one SSB includes 4 symbols in the time domain, and a group of SSB transmission opportunities should complete transmission within one half frame (5 ms). Assume that the index of the first symbol of the first slot within a field is symbol 0:

(1) Case a-15kHz subcarrier spacing:

1) The index of the first symbol of SSB includes {2,8} +14 x n;

2) For unshared spectrum:

(1) the carrier frequency is less than or equal to 3ghz, n=0, 1;

(2) the carrier frequency in FR1 is greater than 3ghz, n=0, 1,2,3;

3) For shared spectrum, n=0, 1,2,3,4.

(2) Case B-30kHz subcarrier spacing:

1) The index of the first symbol of SSB includes {4,8,16,20} +28×n;

(1) carrier frequency is less than or equal to 3ghz, n=0;

(2) the carrier frequency in FR1 is greater than 3ghz, n=0, 1.

(3) Case C-30kHz subcarrier spacing:

1) The index of the first symbol of SSB includes {2,8} +14 x n;

2) For non-shared spectrum and belonging to paired spectrum (e.g., frequency division duplex (Frequency Division Duplex, FDD) scenarios);

(1) The carrier frequency is less than or equal to 3ghz, n=0, 1;

(2) the carrier frequency in FR1 is greater than 3ghz, n=0, 1,2,3;

3) For unshared spectrum and belonging to unpaired spectrum (e.g., time division duplex (Time Division Duplex, TDD) scenarios);

(1) the carrier frequency is less than or equal to 2.4ghz, n=0, 1;

(2) the carrier frequency in FR1 is greater than 2.4ghz, n=0, 1,2,3.

4) For shared spectrum, n=0, 1,2,3,4,5,6,7,8,9.

(4) Case D-120kHz subcarrier spacing:

1) The index of the first symbol of SSB includes {4,8,16,20} +28×n;

(1) for carrier frequencies within FR2, n= 0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18.

(5) Case E-240kHz subcarrier spacing:

1) The index of the first symbol of SSB includes {8,12,16,20,32,36,40,44} +56 x n;

(1) for carrier frequencies within FR2, n= 0,1,2,3,5,6,7,8.

As shown in fig. 1A, a schematic diagram of a portion SSB pattern of the NR system with respect to FR1 under different conditions is shown. As shown in fig. 1B, a schematic diagram of a portion SSB pattern of the NR system with respect to FR2 under different conditions is shown. As shown in fig. 1C, a schematic diagram of a group of SSB transmission opportunities within one half frame is shown, taking SSB patterns in Case a as an example.

In an NR system, the initial access procedure of a terminal device can be accomplished by detecting a synchronization signal Block (Synchronization Signal/PBCH Block, SSB or SS/PBCH Block) on a synchronization grid (Sync Raster). The SSB transmits through a discovery signal transmission opportunity window (Discovery Burst Transmission Window) or SSB transmission opportunity window. Wherein the discovery signal transmission opportunity window may also be referred to as a DRS transmission opportunity window. The DRS transmission opportunity window or SSB transmission opportunity window occurs periodically, which may be configured by the network device through higher layer parameters. The DRS transmission opportunity window or SSB transmission opportunity window may include a set of candidate locations for SSB transmission. For FR1, a maximum of 8 SSBs may be included in a set of SSB transmission opportunities, and for FR2, a maximum of 64 SSBs may be included in a set of SSB transmission opportunities.

SSBs include two types: one is the transmission of a system message, e.g. a system message block (system information block, sib1) or the like, for determining the SSB of a cell, also called cell-defining SSB, associated with the cell, and the terminal device may complete the initial access of the cell after searching for the cell-defining SSB. The cell-defining SSB is always transmitted on the synchronization grid. cell-defining SSBs may be used for SSB-based measurements in addition to initial access of cells. Another is SSB not used for determining a cell, also called non cell-defining SSB, which is not associated with system message transmission of the cell, and indication information is included in a physical broadcast channel (Physical Broadcast Channel, PBCH) of the non cell-defining SSB, which is used for indicating a location of the cell-defining SSB. After the terminal device searches the non-cell-defining SSB, the terminal device can receive the cell-defining SSB according to the indication information, so as to complete the initial access of the cell. The non-cell-defining SSB may or may not be transmitted on the synchronization grid. The non-cell-defining SSB is mainly used for the terminal equipment to measure based on the SSB.

The network device indicates the actually transmitted SSB through indication information, wherein the indication information comprises SSB-positioning inburst in SIB1 and SSB position indication information in transmission opportunities in service cell common configuration (ServingCellConfigCommon); such as configuration information provided by ssb-PositionInBurst. The terminal device expects that the configuration information provided by ssb-PositionInBurst in ServerCellConfigCommon is the same as the configuration information provided by ssb-PositionInBurst in SIB 1. The terminal device may determine the actually transmitted SSB by an indication of the network device, e.g. SSB-locationinburst. The indication information corresponds to a bit map (bitmap), wherein bit 1 in the bitmap corresponds to SSB index 0, bit 2 in the bitmap corresponds to SSB index 1, and so on. As an example, if the bit is 0, it indicates that the SSB corresponding to the bit is not transmitted, and if the bit is 1, it indicates that the SSB corresponding to the bit is transmitted. For example, assuming that the bitmap corresponding to SSB-locationinburst on one serving cell is [10100000], SSB indexes that illustrate SSBs transmitted on the serving cell are SSB 0 and SSB 2.

When the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the SI-RNTI (System Information Radio Network Temporary Identifier, system information radio network device temporary identifier) is received and the system information included in the downlink control information (Downlink Control Information, DCI) corresponding to the SI-RNTI is indicated as 0 (or when the PDSCH scheduled by the SI-RNTI includes SIB1 information), the terminal device shall assume that no RE is included in the Resource Element (RE) included in the received PDSCH for SSB transmission.

When a PDSCH scheduled by SI-RNTI is received and system information included in DCI corresponding to SI-RNTI indicates 1 (or when system information other than SIB1 is included in PDSCH scheduled by SI-RNTI is received), or a PDSCH scheduled by RA-RNTI (Random Access RNTI ), msgB-RNTI, P-RNTI (Paging RNTI) or TC-RNTI (Temporary C-RNTI), or a PDSCH scheduled by cyclic redundancy code (Cyclic Redundancy Code, CRC) is received, a physical resource block (Physical Resource Block) in the scheduled PDSCH is overlapped with a PDSCH (Cell RNTI), MCS-C-RNTI (Modulation and Coding Scheme C-RNTI), modulation coding scheme C-RNTI) or CS-RNTI (Configured Scheduling RNTI, configuration scheduling RNTI), or a PDSCH scheduled by Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) is received, the terminal device shall assume a SSB to be transmitted according to the indication information such as SSB-positioning RNTI, or if a physical resource block (Physical Resource Block, CRC) in the scheduled PDSCH is overlapped with a PDSCH used for transmission of a PRB (PRB) or a device used for transmission of a PRB which is not overlapped with a PRB.

In the NTN scenario shown in the embodiment of the present application, one satellite may serve multiple root print through multiple beams, where one root print may be considered as one coverage area of the ground, and may also be referred to as a coverage cell. Wherein the plurality of root print correspond to the same cell Identity (ID) or to the same satellite cell. Fig. 2A is a schematic diagram of an NTN scenario according to an embodiment of the present invention.

One root print may correspond to one or more beams. Specifically, taking one slot print corresponding to one beam as an example, 3 cases may be included in the NTN network deployment scenario based on the beam:

case 1: the Frequency reuse factor (Frequency re-use factor) is 1, as shown in fig. 2B, which is a schematic diagram of the Frequency reuse factor 1 in the NTN scenario.

Case 2: the Frequency reuse factor (Frequency re-use factor) is 3, as shown in fig. 2C, which is a schematic diagram of the Frequency reuse factor of 3 in the NTN scenario.

Case 3: the Frequency reuse factor (Frequency re-use factor) is 2, as shown in fig. 2D, which is a schematic diagram of the Frequency reuse factor of 2 in the NTN scenario.

However, in the NTN system, when one network device (for example, a satellite) serves a plurality of terrestrial coverage cells (root print) through multiple beams, and the plurality of root print correspond to the same cell ID, different root print may correspond to different frequency bands in the system bandwidth. In the embodiment of the present application, how the terminal device performs initial access of the cell or rate matching of downlink data reception based on SSB is a problem mainly discussed in the present application.

The network formed between the terminal device 1201, the satellite 1202 and the base station 1203 may also be referred to as NTN. In the architecture of the communication system shown in fig. 3C, the satellite 1202 may not have the function of a base station, and communication between the terminal device 1201 and the base station 1203 needs to pass through the transit of the satellite 1202. Under such a system architecture, the base station 1203 may be referred to as a network device. Alternatively, a plurality of network devices 1203 may be included in the communication system, and the coverage area of each network device 1203 may include other number of terminal devices, which is not limited in the embodiment of the present application.

Taking a Band Width Part (BWP) as an example for each segment of frequency resource in the case 2 corresponding to fig. 2C, one root print corresponds to one BWP, and different SSB indexes can be corresponding to different BWP in the NTN network. Fig. 4A is an exemplary diagram of a beam-based NTN networking scenario according to an embodiment of the present invention. In fig. 4A, B represents a beam, or an index of SSB, for example, B0 refers to SSB0, B1 refers to SSB1, and the like. FP represents an overlay cell on the ground as shown by a hexagon, e.g., FP0 represents that the overlay cell ID is 0, fp1 represents that the overlay cell ID is 1, etc. BWP0 indicates that the ID of the BWP corresponding to the overlay cell is 0, BWP1 indicates that the ID of the BWP corresponding to the overlay cell is 1, and so on.

It should be understood that this SSB transmission manner is merely an example, and the embodiments of the present application may also be applied to other scenarios of SSB transmission, which is not limited in this application. In these examples, it is assumed that the number of SSBs that the network device needs to send is 8, i.e. a set of SSB transmissions includes 8 SSBs, where different BWP corresponding different beams are used to transmit different or identical SSB indexes, BWP identification and SSB index may be in one-to-many relationship, as shown in fig. 4A, corresponding beams in BWP0 are SSB0 and SSB7, corresponding beams in BWP1 are SSB1, SSB3 and SSB5, and corresponding beams in BWP2 are SSB2, SSB4 and SSB6.

Several ways of SSB transmission by the network device are described below, respectively, as follows:

mode 1: referring to fig. 4b, the SSB transmission method is different from Rel-15 in that the cell-defined SSBs are transmitted on the respective corresponding BWP according to the association relationship between the SSB index and the BWP identifier. That is, SSB0 and SSB7 are transmitted through BWP0, SSB1, SSB3 and SSB5 are transmitted through BWP1, and SSB2, SSB4 and SSB6 are transmitted through BWP 2.

In addition, BWP1 and BWP2 are also transmitted with part of SSBs in the set of SSBs, and the BWP1 or BWP2 has an association relationship with part of SSBs in the set of SSBs transmitted on BWP 0. Namely SSB1, SSB3 and SSB5 are also sent via BWP1, and SSB2, SSB4 and SSB6 are also sent via BWP 2. Wherein the SSB transmitted on BWP1 and BWP2 is a non cell-defining SSB.

Optionally, SSBs transmitted on BWP1 and BWP2 also need to be sent on the synchronization grid.

Mode 3: referring to fig. 4d, the SSB transmission method is similar to Rel-15, assuming BWP0 is an initial BWP in a cell, the set of SSBs is transmitted through BWP0, and the set of SSBs is a cell-defined SSB. In addition, the set of SSB transmissions is also on BWP1 and BWP2, and the SSB transmitted on BWP1 and BWP2 is a non-cell-defining SSB.

Mode 4: referring to fig. 4e, the SSB transmission method is the same as Rel-15, and assuming BWP0 is an initial BWP in a cell, the set of SSBs is transmitted through BWP0 and the set of SSBs is cell-defined SSBs. There may be no SSB transmission on BWP1 and/or BWP 2.

For example, the first indication information is used to indicate the SSB transmitted (or not transmitted) in the first SSB transmission opportunity on the first synchronization grid.

And the association relation between the index of at least one SSB in the SSB and the frequency domain position of the at least one SSB in the transmission of the at least one SSB.

As an example, the association relationship of the overlay cell ID and the BWP ID includes: q=p mod N, where p denotes the overlay cell ID, q denotes the BWP ID, and N denotes the number of BWP. For example, assuming that the frequency band in a cell can be divided into 3 BWP, the BWP IDs q corresponding to the coverage cells with the coverage cell IDs p of 0 to 9 are respectively: 0. 1, 2, 0, 1, 2, 0.

As an example, the association relationship of the overlay cell ID and the SSB index includes: s=p mod N, where p denotes the overlay cell ID, s denotes the SSB index, and M denotes the number of SSBs transmitted. For example, assuming that the number of SSBs transmitted in SSB transmission opportunities in a cell is 6 SSBs, SSB indexes corresponding to overlay cells having overlay cell IDs p of 0 to 9 are respectively: 0. 1, 2, 3, 4, 5, 0, 1, 2, 3.

As an example, the association relationship of the SSB index and the BWP ID includes: q=s mod N, where s denotes SSB index, q denotes BWP ID, and N denotes the number of BWP. For example, assuming that the frequency band in the cell may be divided into 3 BWP, and the number of SSBs transmitted in the SSB transmission opportunity is 8 SSBs, the SSB index s is 0 to 7, and the corresponding BWP IDs q are respectively: 0. 1, 2, 0, 1, 2, 0.

Optionally, the SSB includes an SSB in an SSB transmission window; alternatively, the SSB includes an SSB in a DRS transmission window.

It is to be appreciated that different frequency domain locations may be considered as one transmission opportunity or may be considered as multiple transmission opportunities.

The indication information of the frequency domain position of the SSB includes indication information of the frequency domain position of the SSB in a plurality of transmission opportunities, wherein the indication information of the frequency domain position of the SSB in different transmission opportunities is associated with different frequency domain positions. For example, assuming that the bitmap (bitmap) corresponding to SSB-location infurst on one serving cell includes [10000001] associated with BWP0, [01010100] associated with BWP1, and [00101010] associated with BWP2, SSB indexes indicating SSB transmitted on the serving cell are SSB0 and SSB7 transmitted through BWP0, SSB1, SSB3, and SSB5 transmitted through BWP1, and SSB2, SSB4, and SSB6 transmitted through BWP 2.

Optionally, the method further comprises: and when the terminal equipment receives the first PDSCH scheduled by the PDCCH with the CRC scrambling code of the SI-RNTI and the system information included in the DCI in the PDCCH is indicated as 0, or receives the first PDSCH scheduled by the PDCCH with the CRC scrambling code of the SI-RNTI and the SIB1 is included in the first PDSCH, the terminal equipment determines that no RE is used for SSB transmission in resource elements RE included in the first PDSCH. Further optionally, the first PDSCH includes the first indication information.

In the embodiment of the present invention, a terminal device receives first indication information sent by a network device, where the first indication information is used to indicate a frequency domain position of a synchronization signal block SSB and/or a coverage cell corresponding to the SSB. The terminal equipment can complete initial access and data rate matching of downlink reception according to the first indication information. By the method, under the condition that the frequency multiplexing factor of the NTN system is larger than 1, the terminal equipment of different coverage cells on the ground can accurately complete the initial access of the NTN system and the rate matching of downlink data reception.

In the following, referring to fig. 4A, taking an example that the terminal device is located in BWP2, B6, and boot print0, description will be given by taking first indication information corresponding to the SSB transmission method in each of the 4 modes of the foregoing example, initial access behavior of the terminal device, and downlink receiving rate matching based on SSB as an example.

Mode 1:

the first indication information is used for indicating a frequency domain position of the SSB and/or a coverage cell corresponding to the SSB in the DRS transmission opportunity window or the SSB transmission opportunity window. As an example, the first indication information indicates a frequency domain location of the SSB, which may be: the first indication information indicates an association relationship of the BWP identification and the SSB index transmitted in the SSB transmission opportunity in the BWP. For example, the first indication information includes 3 rows of bitmaps, each row of bitmaps includes 8 bits, each row of bitmaps is associated with a BWP ID, where the first row of bitmaps is [10000001] for indicating SSBs transmitted in SSB transmission opportunities on BWP0 as SSB0 and SSB7; the second row of bitmaps is [01010100] for indicating SSBs transmitted in SSB transmission opportunities on BWP1 as SSB1, SSB3, and SSB5; the third row of bitmaps is [00101010] for indicating that the SSBs transmitted in the SSB transmission opportunity on BWP2 are SSB2, SSB4, and SSB6.

Optionally, the first indication information indicates a frequency domain location of the cell-defining SSB.

Optionally, the first indication information is transmitted through at least one of PBCH, MIB and SIB 1. For example, the first indication information comprises ssb-PositionInBurst in SIB 1.

Optionally, the first indication information is transmitted through higher layer signaling. For example, the first indication information includes ssb-PositionInBurst in ServerCellConfigCommon.

Optionally, the configuration information provided by the first indication information included in the different configuration parameters is the same.

As an example, the first indication information indicates the coverage cell corresponding to the SSB, which may be: the first indication information indicates an association relationship of the overlay cell ID and the SSB index transmitted in the SSB transmission opportunity in the BWP.

When the terminal device performs initial access, it may detect SSB6 in BWP2 and access the network through SSB6 in the detected BWP2, because its geographical location FP0 corresponds to the coverage area of BWP2, B6. It is understood that BWP2 herein may be an active BWP or an initial BWP. Further, the terminal device may receive the first indication information according to the system message associated with the SSB6, and determine SSB transmitted on different BWP in the cell, or association information of BWP and SSB, or association information of overlay cell and BWP, or association information of overlay cell, BWP and SSB according to the first indication information. The terminal device may measure the corresponding BWP according to the SSB information transmitted on the different BWP, or the terminal device may determine the corresponding BWP information after detecting the SSB on the other BWP.

Optionally, the terminal device determines that SSB of the BWP2 transmission includes SSB2, SSB4 and SSB6 according to the first indication information, so as to determine rate matching of downlink data reception.

When the terminal device receives PDSCH scheduled by SI-RNTI and the system information included in DCI corresponding to SI-RNTI indicates 0 (or when PDSCH scheduled by SI-RNTI includes SIB1 information), the terminal device should assume that no RE in REs included in the received PDSCH is used for SSB transmission.

When the terminal device receives PDSCH scheduled by SI-RNTI and system information included in DCI corresponding to the SI-RNTI indicates 1 (or when PDSCH scheduled by SI-RNTI includes system information other than SIB 1), or PDSCH scheduled by RA-RNTI, msgB-RNTI, P-RNTI, or TC-RNTI is received, or PDSCH scheduled by PDCCH with CRC scrambling code of C-RNTI, MCS-C-RNTI, or CS-RNTI is received, or SPS PDSCH is received, the terminal device should determine that SSB transmitted by BWP2 includes SSB2, SSB4, and SSB6 according to the first indication information. If the PRBs in the scheduled PDSCH overlap with the PRBs used for transmission of SSBs (i.e., SSB2, SSB4, or SSB 6), then the terminal device should assume that the resource corresponding to the overlapping PRBs on the symbols of the SSB transmission (or resources used for transmission of SSB) is not used for PDSCH transmission.

Mode 2:

the first indication information is used for indicating a frequency domain location of the SSB, DRS transmission opportunity window or a frequency domain location of the SSB in the SSB transmission opportunity window and/or a coverage cell corresponding to the SSB. As an example, the first indication information indicates a frequency domain location of the SSB, which may be: the first indication information indicates an association relationship of the BWP identification and the SSB index transmitted in the SSB transmission opportunity in the BWP. For example, the first indication information includes 3 rows of bitmaps, each row of bitmaps includes 8 bits, each row of bitmaps is associated with a BWP ID, where the first row of bitmaps is [11111111] for indicating SSBs transmitted in SSB transmission opportunities on BWP0 as SSB0 to SSB7; the second row of bitmaps is [01010100] for indicating SSBs transmitted in SSB transmission opportunities on BWP1 as SSB1, SSB3, and SSB5; the third row of bitmaps is [00101010] for indicating that the SSBs transmitted in the SSB transmission opportunity on BWP2 are SSB2, SSB4, and SSB6.

Alternatively, the SSB transmitted in BWP0 is a cell-defining SSB, and the SSB transmitted in BWP1 and BWP2 is a non-cell-defining SSB.

Optionally, the terminal device determines the initial BWP according to the indication information of the network device, for example, since the SSBs transmitted in the first row include SSBs transmitted in the second row and the third row, the terminal device may determine that the SSB transmitting cell-defining is BWP0 according to the first indication information, or the first indication information is further used to indicate the location of the initial BWP.

When the terminal device performs initial access, because the geographic position where the terminal device is located is FP0 and corresponds to the coverage area of BWP2 and B6, the terminal device can detect SSB6 in BWP2, and after searching for non-cell-defining SSB6 in BWP2, the terminal device can receive the cell-defining SSB according to the indication information in SSB6 in BWP2 to the position of SSB6 in BWP1, thereby accessing the network. It is understood that BWP2 herein may be an active BWP. Further, the terminal device may receive the first indication information according to a system message associated with SSB6 on BWP1 or a PBCH or MIB in BWP2, and determine SSB transmitted on a different BWP in the cell, or association information of BWP and SSB, or association information of overlay cell and BWP, or association information of overlay cell, BWP and SSB according to the first indication information. The terminal device may measure the corresponding BWP according to the SSB information transmitted on the different BWP, or the terminal device may determine the corresponding BWP information after detecting the SSB on the other BWP.

The terminal device determines that SSB of the BWP2 transmission includes SSB2, SSB4 and SSB6 according to the first indication information, and further determines rate matching of downlink data reception.

Mode 3:

the first indication information is used for indicating a frequency domain position of the SSB and/or a coverage cell corresponding to the SSB in the DRS transmission opportunity window or the SSB transmission opportunity window. As an example, the first indication information indicates a frequency domain location of the SSB, which may be: the first indication information indicates a BWP identification including SSB transmission opportunities, wherein SSB indexes transmitted in each SSB transmission opportunity are the same. For example, the first indication information includes 1 row of 8 bits of bitmaps, each row of bitmaps is associated with a BWP ID, where the bitmaps are [11111111] and are used to indicate SSBs transmitted in SSB transmission opportunities as SSB0 to SSB7; the first indication information further includes BWP index indication information or a frequency domain position of the first RB in BWP corresponding to the BWP index, for indicating the BWP in the cell to transmit the SSB transmission opportunity. For example, assuming that at most 4 BWP can be included in the cell, the first indication information further includes 1 row of 4 bits of bitmap [1110] for indicating SSB including transmission in SSB transmission opportunities on BWP0, BWP1 and BWP 2.

Optionally, the terminal device determines the initial BWP according to the indication information of the network device, for example, the first indication information is further used to indicate the location of the initial BWP, and the terminal device may determine that the SSB for transmitting cell-defining is BWP0 according to the first indication information.

When the terminal device performs initial access, since the geographic location FP0 where the terminal device is located corresponds to the coverage of the BWP2 and B6, it can detect the SSB6 in the BWP2, and since the SSB6 in the BWP2 is a non-cell-defining SSB, the terminal device, after searching the non-cell-defining SSB6 in the BWP2, can receive the cell-defining SSB according to the indication information in the SSB6 in the BWP2 to the location of the SSB6 in the BWP1, thereby accessing the network. It is understood that BWP2 herein may be an active BWP. Further, the terminal device may receive the first indication information according to a system message associated with SSB6 on BWP1 or a PBCH or MIB in BWP2, and determine SSBs transmitted on different bwtps in the cell according to the first indication information. The terminal device may measure the corresponding BWP according to the SSB information transmitted on the different BWP, or the terminal device may determine the corresponding BWP information after detecting the SSB on the other BWP.

The terminal device determines that SSB of the BWP2 transmission includes SSB0 to SSB7 according to the first indication information, and further determines rate matching of downlink data reception.

When the terminal device receives PDSCH scheduled by SI-RNTI and system information included in DCI corresponding to the SI-RNTI indicates 1 (or when PDSCH scheduled by SI-RNTI includes system information other than SIB 1), or PDSCH scheduled by RA-RNTI, msgB-RNTI, P-RNTI, or TC-RNTI is received, or PDSCH scheduled by PDCCH with CRC scrambling code of C-RNTI, MCS-C-RNTI, or CS-RNTI is received, or SPS PDSCH is received, the terminal device should determine that SSB transmitted by BWP2 includes SSB2, SSB4, and SSB6 according to the first indication information. If the PRBs in the scheduled PDSCH overlap with the PRBs used for transmitting SSBs (i.e., at least one of SSBs 0 to 7), then the terminal device should assume that the resource corresponding to the overlapping PRBs on the symbols of SSB transmission (or resources used for transmitting SSBs) is not used for PDSCH transmission.

Mode 4:

the first indication information is used for indicating a frequency domain position of the SSB and/or a coverage cell corresponding to the SSB in the DRS transmission opportunity window or the SSB transmission opportunity window. As an example, the first indication information indicates a frequency domain location of the SSB. Since this way is the same as the SSB transmission way of Rel-15, the first indication information comprises SSB-posi-lnburst. For example, the first indication information includes 1 row of 8 bits of bitmaps, each row of bitmaps is associated with a BWP ID, where the bitmaps are [11111111] and are used to indicate SSBs transmitted in SSB transmission opportunities as SSBs 0 to SSB7. The first indication information further includes a BWP identifier or indication information of association between the frequency domain location of the first RB in the BWP corresponding to the BWP identifier and the SSB index, for indicating the SSB index associated on the BWP in the cell. For example, the first indication information is used to indicate the association relationship as shown in table 2 below.

Boot print identifier	BWP identification	SSB index
0	BWP0	0
1	BWP1	1
2	BWP2	2
3	BWP1	3

WiFi belongs to a short-distance wireless transmission technology, and a mobile phone can help a user to send and receive emails, browse webpages, access streaming media and the like through a WiFi module 870, so that wireless broadband Internet access is provided for the user. Although fig. 8 shows a WiFi module 870, it is understood that it does not belong to the necessary constitution of the handset, and can be omitted entirely as needed within the scope of not changing the essence of the invention.

The processor 880 is a control center of the mobile phone, connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions of the mobile phone and processes data by running or executing software programs and/or modules stored in the memory 820 and calling data stored in the memory 820, thereby performing overall monitoring of the mobile phone.
