FIG. 2 is a schematic diagram of a data transmission method according to Embodiment 1 of the present invention. As shown in FIG. 2, the method includes:

Step 201: Receive downlink signals and/or channels on a first time-frequency resource according to predefined first rules and/or received first indication information, and/or,

Step 202: Send an uplink signal and/or channel on a first time-frequency resource according to the predefined second rule and/or the received second indication information,

Wherein, at least one resource element (Resource) (RE) in the first time-frequency resource and at least one RE in the second time-frequency resource overlap, the second time-frequency resource corresponds to the first SSB, and the downlink signal And/or channel is a downlink signal and/or channel other than SSB.

In this way, by pre-defined rules and/or received indication information, other signals and/or channels other than SSB can be sent or received on time-frequency resources that overlap with the time-frequency resources corresponding to the SSB, and the SSB can be sent unnecessarily. Transmit and receive other signals and/or channels on the corresponding time-frequency resources, thereby effectively improving resource utilization.

In this embodiment, the data transmission method can be applied to various frequency bands. For example, it can be used in licensed bands, unlicensed bands or shared bands.

In this embodiment, step 201 and step 202 may be executed one of them, or may be executed at different times, but the order of execution is not limited.

In addition, when both

steps

201 and 202 are executed at different times, the first time-frequency resources used in

steps

201 and 202 are different.

The difference here means that no one RE overlaps.

In this embodiment, the downlink signal and/or channel is, for example, at least one of a downlink reference signal, a physical downlink control channel (Physical Downlink Control Channel, PDCCH), and a physical downlink data channel (Physical Downlink Shared Channel, PDSCH). Uplink signals and/or channels are Physical Random Access Channel (Physical Random Access Channel, PRACH), uplink reference signal (for example, Sounding Reference Signal (SRS)), Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH ) And at least one of a physical uplink data channel (Physical Uplink Shared Channel, PUSCH).

In this embodiment, at least one RE in the first time-frequency resource and at least one RE in the second time-frequency resource overlap, and the second time-frequency resource corresponds to the first SSB, that is, according to the pre- The defined first SSB set, the second time-frequency resource is reserved for sending the first SSB (the first SSB is one of the first SSB set), and it overlaps at least part of the first time-frequency resource of.

In this embodiment, steps 201 and 202 are for receiving downlink signals and/or channels and for transmitting uplink signals and/or channels, respectively. The first rule and the second rule may be the same or different. The received first indication information and second indication information may be the same or different.

In this embodiment, the specific description is mainly for receiving downlink signals and/or channels. For the implementation of sending uplink signals and/or channels, reference may be made to the content of receiving downlink signals and/or channels.

Hereinafter, the case of receiving a downlink signal and/or channel will be described first.

FIG. 3 is another schematic diagram of the data transmission method according to Embodiment 1 of the present invention. As shown in FIG. 3, the method includes:

Step 301: Receive a downlink signal and/or channel on a first time-frequency resource according to a predefined first rule and/or received first indication information,

Wherein, at least one RE in the first time-frequency resource and at least one RE in the second time-frequency resource overlap, the second time-frequency resource corresponds to the first SSB, and the downlink signal and/or channel is outside the SSB Downstream signals and/or channels.

As shown in FIG. 3, the method may further include:

Step 302: Determine to receive the downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and/or the first indication information.

In step 302, determining to receive the downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and/or the first indication information means that according to the predefined first rule and/or Or, when the first indication information determines whether to receive the downlink signal and/or channel on the first time-frequency resource, the determination result is “yes”. When the determination result is “No”, it is determined that the downlink signal and/or channel is not received on the first time-frequency resource.

That is, when the priority of the first SSB is higher than the downlink signal and/or channel, the determination is "No", and the downlink signal and/or channel is not received on the first time-frequency resource; when the first SSB's When the priority is lower than the downlink signal and/or channel, the determination is "Yes", and the downlink signal and/or channel is received on the first time-frequency resource.

In step 302, it is determined to receive the downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and/or the first indication information.

In this embodiment, when receiving different downlink signals and/or channels, the first rule and/or the first indication information may be the same or different.

For example, when receiving the PDCCH, the PDCCH may be determined to be received on the first time-frequency resource according to the predefined first rule and/or the first indication information; when receiving the PDSCH, it may be determined according to another predefined first rule and Or another first indication information determines to receive the PDSCH on the first time-frequency resource.

In the following, the downlink signals and/or channels are determined to be received on the first time-frequency resource according to the predefined first rule, and the downlink signals and/or channels are determined to be received on the first time-frequency resource according to the first indication information And three cases of determining that the downlink signal and/or channel is received on the first time-frequency resource according to the predefined first rule and the first indication information are described.

Solution 1. Determine to receive the downlink signal and/or channel on the first time-frequency resource according to a predefined first rule.

For example, the first rule means that when the first SSB belongs to a second SSB set, it does not receive downlink signals and/or channels on a first time-frequency resource; when the first SSB belongs to the first SSB set, but When it does not belong to the second SSB set, receive the downlink signal and/or channel on the first time-frequency resource,

The second SSB set is a subset of the first SSB set, and each SSB in the first SSB set corresponds to a different time domain position of a transmission window. In this embodiment, the time domain position and the number of SSBs sent in different transmission windows may be the same or different.

In this embodiment, a transmission window may be a periodic time transmission unit. For example, the transmission window is an SSB transmission window, a DRS (Demodulation Reference Signal, Demodulation Reference Signal) transmission window, a half-subframe, and a subframe. one of.

In this embodiment, each SSB in the first SSB set corresponds to a different time domain position of the transmission window. The number of SSBs in the first SSB set may be set according to actual needs.

For example, the number of SSBs in the first SSB set may be set according to actual needs, for example, 8, 16, 32 or 64.

In this embodiment, the first SSB set is predefined.

Here, the pre-defined means that at least one of the number of SSBs included in the first SSB set, the time domain position, and the quasi-co-location relationship is defined in the standard. The first SSB set is, for example, defined according to the regulatory requirements of unlicensed frequency bands to share spectrum resources as fair as possible.

In this embodiment, according to the quasi-co-location relationship between the SSBs, that is, according to the airspace information corresponding to the SSB, such as the second index, beam identification, SSBs corresponding to the same and unique airspace information are quasi-co-located. For example, the first SSB set is related to the frequency band (or frequency range) and/or sub-carrier spacing (SCS), that is, the corresponding first frequency band (or frequency range) and/or sub-carrier spacing are respectively defined as the corresponding first SSB collection.

Taking a frequency band as an example, for example, for the frequency bands F1 to F2 kHz, the first SSB set includes 8 SSBs SSB1 to SSB8, and for the frequency bands F3 to F4 kHz, the second SSB set includes 16 SSBs SSB1 to SSB16. For other frequency bands, similar settings can be made.

For example, for the time domain position of the SSB, the correspondence between the SSB and the first index is predefined, or the relationship between the SSB and the second index and the third index is predefined;

For the quasi-co-location relationship of the SSB, the correspondence between the SSB and the second index is predefined.

In this embodiment, each SSB in the first SSB set corresponds to a different time-domain position of the transmission window, where the different time-domain position refers to not exactly the same, that is, the The time domain positions of any two SSBs may be spaced apart or partially overlapped.

FIG. 4 is a schematic diagram of the first SSB set of Embodiment 1 of the present invention. As shown in FIG. 4, multiple transmission windows are periodically provided on the time axis, and a period T is, for example, 40 ms. One transmission window is one of multiple transmission windows. The first SSB set contains 16 SSBs, and these 16 SSBs are spaced from each other in the time domain.

FIG. 5 is another schematic diagram of the first SSB set of Embodiment 1 of the present invention. As shown in FIG. 5, the first SSB set includes 16 SSBs, and these 16 SSBs partially overlap in the time domain.

In this embodiment, the SSB in the first SSB set may be referred to as a nominal SSB (nominal SSB), but this name is only used to distinguish it from the existing SSB, and other names may also be used.

In this embodiment, the second SSB set is a subset of the first SSB set. For example, the second SSB set may be the first SSB set itself or a true subset of the first SSB set, that is, it contains the first SSB part of the SSB set.

In this embodiment, the SSB in the second SSB set may be referred to as a candidate SSB (candidate SSB), but the name is only to distinguish it from the existing SSB and the SSB in the first SSB set, and it may also use other name.

For example, for a certain SSB in the first SSB set, it is a nominal SSB. If the nominal SSB belongs to the second SSB set, the nominal SSB is also a candidate SSB.

In scheme 1, the second SSB set is predefined, that is, the SSBs contained in the second SSB set are predetermined.

Here, the pre-defined means that a specific value of I is defined in the standard, for example, I is defined according to the regulatory requirements of unlicensed frequency bands, so as to share spectrum resources as fair as possible.

For example, I is related to the frequency band (or frequency range) and/or sub-carrier spacing (SCS), that is, the corresponding minimum transmission number I is defined for different frequency bands (or frequency ranges) and/or sub-carrier spacing, respectively .

Taking a frequency band as an example, for example, for frequency bands F1 to F2 kHz, I=4, and for frequency bands F3 to F4 kHz, I=2. For other frequency bands, similar settings can be made.

For another example, the first rule means that when the first SSB belongs to a third SSB set, it does not receive downlink signals and/or channels on the first time-frequency resource; when the first SSB belongs to the first SSB set, However, when it does not belong to the third SSB set, receive the downlink signal and/or channel on the first time-frequency resource,

Wherein, the third SSB set is a subset of the first SSB set, and each SSB in the first SSB set corresponds to different time domain resources of a transmission window.

For the first SSB set, please refer to the above description.

In this embodiment, the third SSB set is a subset of the first SSB set, and the SSB in the third SSB set may be called a transmitted SSB (transmitted SSB), but the name is only to distinguish it from the existing SSB As well as the SSBs in the first SSB set and the second SSB set, they can also use other names.

For example, for a certain SSB in the first SSB set, it is a nominal SSB. If the nominal SSB belongs to the second SSB set, the nominal SSB is also a transmitted SSB.

In this embodiment, the correspondence between the third SSB set and the first SSB set or the second SSB set may be predefined.

For example, the SSBs in the third SSB set are the first X SSBs in the first SSB set or the second SSB set.

For example, the value of X is related to the number of values of the second index or the fourth index corresponding to the SSB in the second SSB set, for example, X=P×R, and R represents the number of the second corresponding to the SSB in the second SSB set. The number of values of the second index, P≥1, the value of P is predefined, and the second index and the fourth index will be described in detail later;

For another example, the value of X is related to the number of SSBs in the second SSB set, for example, X=Q×S, S represents the number of SSBs in the second SSB set, 0<Q<1, Q takes The value is predefined;

For another example, the value of X is related to the maximum number of SSBs sent in a transmission window, and the maximum number of SSBs sent in a transmission window is predefined or pre-configured;

For another example, the value of X is predefined.

In this embodiment, the third SSB set and the second SSB set may or may not have a predetermined relationship. For example, the third SSB set is a subset of the second SSB set, or the second SSB set is a subset of the third SSB set.

6 is a schematic diagram of a third SSB set in Embodiment 1 of the present invention. As shown in Figure 6, the third SSB set is a subset of the second SSB set. On the time axis, when successful listening first (Listen Before Talk, LBT) appears in the first SSB of the second SSB set Previously, the SSBs in the third SSB set were determined according to the correspondence between the third SSB set and the second SSB set.

7 is another schematic diagram of the third SSB set of Embodiment 1 of the present invention. As shown in FIG. 7, the third SSB set is a subset of the second SSB set. On the time axis, when a successful LBT appears after the first SSB of the second SSB set, the corresponding The third SSB set of the second SSB set.

8 is another schematic diagram of a third SSB set in Embodiment 1 of the present invention. As shown in FIG. 8, the SSBs in the third SSB set may be SSBs other than the second SSB set.

In scheme 1, the third SSB set is predefined, that is, the SSBs included in the third SSB set are predetermined.

For another example, the first rule means that when the first SSB belongs to a first SSB set, it does not receive downlink signals and/or channels on a first time-frequency resource; when the first SSB does not belong to the first SSB During aggregation, downlink signals and/or channels are received on the first time-frequency resource, and the time domain positions of the two SSBs in the first SSB set overlap. The first SSB set is predefined, that is, the SSBs included in the first SSB set are predetermined. In this way, the resources reserved for the SSB can be reduced while increasing the SSB transmission opportunities, thereby reducing resource waste and improving resource utilization.

FIG. 9 is another schematic diagram of the data transmission method according to Embodiment 1 of the present invention. As shown in FIG. 9, the method includes:

Step 901: Receive first indication information indicating that the downlink signal and/or channel is received on the first time-frequency resource;

Step 902: Determine, according to the first indication information, to receive a downlink signal and/or channel on the first time-frequency resource;

Step 903: Receive downlink signals and/or channels on the first time-frequency resource according to the first indication information. In this embodiment, the first indication information may be sent through higher layer signaling or physical layer signaling.

For example, through RRC signaling or MAC CE transmission.

Among them, since the network device needs to access the channel according to the channel detection result, it may not be able to predict the time domain position where the channel can be occupied, and sending the first indication information through physical layer signaling can more flexibly adapt to the dynamic channel access situation.

In scheme 2, the first indication information may directly indicate whether to receive the downlink signal and/or channel on the first time-frequency resource. Alternatively, the first indication information indirectly indicates whether the UE receives downlink signals and/or channels on the first time-frequency resource.

For example, by indicating the uplink and downlink configuration (or, transmission direction) corresponding to the first time-frequency resource, it is indirectly indicated whether the UE receives the downlink signal and/or channel on the first time-frequency resource; for another example, by indicating the first time-frequency resource The starting position of the corresponding COT and/or the channel occupation time range indirectly indicate whether the UE receives the downlink signal and/or channel on the first time-frequency resource.

For example, the priority of the downlink signal and/or channel other than the first SSB and the SSB is determined through the first indication information. When the priority of the first SSB is higher, the downlink signal and the downlink signal are not received on the first time-frequency resource. /Or channel, when the priority of the first SSB is low, the downlink signal and/or channel is received on the first time-frequency resource.

The physical layer signaling is, for example, information carried by DCI or downlink reference information.

For example, the DCI includes the first indication information (for example, 1-bit information), and the first indication information indicates whether the UE receives the corresponding downlink signal/channel (for example, PDSCH) on the first time-frequency resource, or the first indication The information indicates whether the UE receives the corresponding PDSCH through rate matching according to the second time-frequency resource corresponding to the first SSB. The first time-frequency resource overlaps with the second time-frequency resource corresponding to the first SSB. Specifically, the overlap between the first time-frequency resource and the second time-frequency resource corresponding to the first SSB means that at least one RE of the first time-frequency resource and at least one RE of the second time-frequency resource corresponding to the first SSB An RE has overlaps.

Further, the DCI may also indicate the first time-frequency resource. For example, assuming the same DCI format, the UE needs to determine whether the DCI corresponds to the time-frequency resources corresponding to the SSBs in the first SSB set or the second SSB set or the third SSB set indicated in the DCI. The first indication information is included to receive the DCI. For example, if the time-frequency resource indicated by the DCI does not overlap with the time-frequency resource corresponding to the SSB in the second SSB set, the DCI does not include the first indication information, and the information bit corresponding to the first indication information is predefined as 0, for example. ; If the time-frequency resource indicated by the DCI overlaps with the time-frequency resource corresponding to the SSB in the second SSB set, the DCI includes the first indication information. For another example, if the time-frequency resource indicated by the DCI does not overlap with the time-frequency resource corresponding to the SSB in the second SSB set, the DCI does not include the first indication information, and the information bit corresponding to the first indication information is, for example, predefined as 0; If the time-frequency resource indicated by the DCI overlaps with the time-frequency resource corresponding to the SSB in the second SSB set, the DCI includes the first indication information. The SSB in the first SSB set is predefined, and the SSB in the second SSB set or the third SSB set is predefined or pre-configured according to the received indication information.

For another example, the DCI indirectly indicates whether the UE receives downlink signals and/or channels on the first time-frequency resource by indicating the uplink and downlink configuration (or, transmission direction) corresponding to the first time-frequency resource. Specifically, the DCI indicates the uplink and downlink configuration of at least one symbol in the first time-frequency resource. For example, if the DCI indicates that the transmission direction corresponding to the symbol in the first time-frequency resource is flexible, the UE monitors or receives downlink signals and/or channels on the first time-frequency resource; otherwise, the UE is not in The first time-frequency resource receives downlink signals and/or channels. The first time-frequency resource overlaps with the second time-frequency resource corresponding to the first SSB.

For another example, the DCI indirectly indicates whether the UE receives the downlink signal/channel on the first time-frequency resource through the start position of the COT corresponding to the first time-frequency resource and/or the channel occupation time range. Specifically, the DCI includes indication information for indicating the COT starting position and/or the channel occupation time range. For example, after receiving the DCI, the UE may determine whether the first time-frequency resource is within the time range of the channel occupied by the base station according to the information, and if it is within the time range, monitor or receive a downlink signal on the first time-frequency resource And/or channel; otherwise, the UE does not receive downlink signals and/or channels on the first time-frequency resource.

Solution 3. Determine to receive the downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and the first indication information.

For example, as in scheme 1, the first rule means that when the first SSB belongs to a second SSB set, it does not receive downlink signals and/or channels on a first time-frequency resource; when the first SSB belongs to the second An SSB set, but not belonging to the second SSB set, receiving downlink signals and/or channels on the first time-frequency resource,

The second SSB set is a subset of the first SSB set, and each SSB in the first SSB set corresponds to different time-domain resources of a transmission window.

Different from solution 1, the second SSB set is semi-statically configured through the received indication information.

FIG. 10 is another schematic diagram of the data transmission method according to Embodiment 1 of the present invention. As shown in FIG. 10, the method includes:

Step 1001: Receive third indication information; the third indication information indicates the second SSB set corresponding to the first rule;

Step 1002: Determine to receive the downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and the third indication information;

Step 1003: Receive a downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and the third indication information.

The third indication information may be the above-mentioned first indication information.

In this embodiment, the third indication information may be sent through higher layer signaling or physical layer instructions.

For example, the high-level signaling is RRC signaling or MAC CE.

In this embodiment, the third indication information corresponds to the first parameter or the second parameter, the first parameter is an existing parameter, and the second parameter is a new parameter.

In this embodiment, the existing parameter is IE (information elements) already supported by RRC signaling in Rel-15NR. The use (or reuse) of existing parameters refers to the use of parameters with the same name as the existing parameters. The information and/or instructions it refers to may vary according to the actual situation, for example, for licensed and unlicensed bands , The information and/or indication methods referred to by the existing parameters are different.

In this embodiment, using the new parameter refers to using the newly introduced parameter IE.

For example, for the case of sending the first indication information through RRC signaling, an existing parameter, such as ssb-PositionsInBurst, may be used for indication, or a new parameter, such as ssb-Positions inBurst-NRU, may also be used for indication.

For example, for authorized bands, the ssb-PositionsInBurst indication includes a set of SSBs sent; for unlicensed bands, ssb-PositionsInBurst (new parameters, such as ssb-PositionsinBurst-NRU) indicates the second SSB set (candidate SSS set ).

For another example, for an unlicensed band, ssb-PositionsInBurst (new parameter, for example, ssb-PositionsinBurst-NRU) indicates that the SSB sent in the second SSB set depends on channel access, or depends on channel access and the above-mentioned maximum transmission number The number of SSBs; and for licensed frequency bands, it does not depend on channel access or the maximum number of SSBs sent above.

For another example, for authorized bands, the time domain positions of SSBs in an SSB set indicated by ssb-PositionsInBurst cannot overlap; for unlicensed bands, an SSB set indicated by ssb-PositionsInBurst (new parameter, such as ssb-PositionsinBurst-NRU) The time domain positions of SSBs in may overlap.

For another example, for Rel-15, for Rel-15, the ssb-PositionsInBurst indication includes a set of SSBs sent; for Rel-16 or other subsequent versions, ssb-PositionsInBurst (new parameters, such as ssb-PositionsinBurst-NRU) Indicate the above-mentioned second SSB set (candidate SSB set).

For another example, for Rel-15, ssb-PositionsInBurst (new parameter, such as ssb-PositionsinBurst-NRU) indicates that the SSB sent in the second SSB set depends on channel access, or depends on channel access and the above Number of SSBs; for Rel-16 or other subsequent versions, it does not depend on channel access or the maximum number of SSBs sent above.

For another example, for Rel-15, the time domain positions of SSBs in an SSB set indicated by ssb-PositionsInBurst cannot overlap; for Rel-16 or other subsequent versions, ssb-PositionsInBurst (new parameters, such as ssb-PositionsinBurst-NRU) The time domain positions of SSBs in an indicated SSB set may overlap.

In this embodiment, the third indication information may directly indicate the second SSB set.

For example, a bit-map is used to indicate which SSBs in the first SSB set belong to the second SSB set, or the indicated number of SSBs, the start position, and the end position in the second SSB set.

For example, the third indication information includes N bits, which correspond to each SSB in the first SSB set. 1 indicates that the corresponding SSB is the SSB in the second SSB set, and 0 indicates that the corresponding SSB is not the SSB in the second SSB set.

FIG. 11 is a schematic diagram indicating a second SSB set according to Embodiment 1 of the present invention. As shown in FIG. 6, the first indication information includes 16 bits, which are 1111110000000000 in sequence, and the SSB corresponding to “1” in the first SSB set is the SSB in the second SSB set.

For another example, the first SSB set is divided into M groups, and the third indication information includes M bits, which correspond to each group of SSBs in the first SSB set. 1 indicates that the SSB in the corresponding group is the SSB in the second SSB set, and 0 indicates that the SSB in the corresponding group is not the SSB in the second SSB set.

In this embodiment, the third indication information may also be based on the time domain position of the SSB in the first SSB set, and/or the quasi-co-location relationship of the SSBs in the first SSB set indicates the second SSB set.

For example, the third indication information indicates the second SSB set based on the correspondence between the SSB in the first SSB set and the first index; the first index indicates that the SSB in the first SSB set is in the one transmission window In the time domain, the SSBs in the first SSB set correspond to the values of the first index.

For another example, the first indication information indicates the second SSB set based on the corresponding relationship between the SSB in the first SSB set and the second index; the second index indicates the standard between the SSBs in the first SSB set The co-location relationship, or in other words, the second index represents spatial information (eg, beam identification) corresponding to the SSBs in the first SSB set, and the SSBs in the first SSB set corresponding to the same second index are quasi-co-located. The first SSB set includes two SSBs corresponding to the same second index value. In this embodiment, the two SSBs corresponding to the same second index value are quasi co-located.

For example, the second index has Y values, and the first indication information includes Y bits, which correspond to each value of the second index. 1 indicates that the SSB corresponding to the corresponding second index is the SSB in the second SSB set, and 0 indicates that the SSB corresponding to the corresponding second index is not the SSB in the second SSB set.

12 is another schematic diagram of indicating a second SSB set according to Embodiment 1 of the present invention. As shown in FIG. 7, the first indication information includes 4 bits, which are 1100 in sequence, the second index has 4 values, which are 0123 in sequence, and the first SSB set includes 16 SSBs, and the corresponding second index is sequentially 0123012301230123, then the SSB corresponding to the second index (values 0 and 1) corresponding to 1 is the SSB in the second SSB set.

In this embodiment, the SSBs in the first SSB set may correspond to one second index, or may correspond to multiple second indexes.

When one SSB corresponds to multiple second indexes, the second SSB set may be indicated according to the correspondence between the SSB and the multiple second indexes.

13 is another schematic diagram of indicating a second SSB set according to Embodiment 1 of the present invention. As shown in FIG. 9, the first indication information includes 4 bits, which are 1100 in sequence. The SSBs in the first SSB set correspond to two second indexes, which are denoted as second index 1 and second index 2, and the second index 1 has 4 values, respectively 0123, and the second index 2 also has 4 values, respectively 3012, then the second index 1 (values 0 and 1) and the second index 2 (value The SSBs corresponding to the

values

3 and 0 are all SSBs in the second SSB set.

In this embodiment, the first SSB set may be predefined or pre-configured.

For example, an SSB in the first SSB set may correspond to a first index value, or may correspond to at least one second index value, or may correspond to a first index value and at least one second index value at the same time. value.

In this embodiment, each SSB in the first SSB set corresponds to a first index. The first index indicates the time domain position of the SSB in the first SSB set in the one transmission window, and the SSBs in the first SSB set correspond to the values of the first index in a one-to-one correspondence.

The UE may determine the time domain position of the SSB in the first SSB set according to the first index, thereby acquiring the frame timing.

In this embodiment, each SSB in the first SSB set may also correspond to at least one second index. The second index indicates a quasi-co-location relationship between the SSBs in the first SSB set. The first SSB set includes two SSBs corresponding to the same second index value.

In this embodiment, each SSB in the first SSB set may correspond to one second index, or may correspond to multiple second indexes.

The UE may determine the airspace information between the SSBs in the first SSB set according to the second index, that is, the quasi-co-location relationship.

In this embodiment, the first index and/or the second index of the SSB in the first SSB set may be indicated. For example, it may be indicated by signals and/or channels in the SSB.

In addition, when each SSB in the first SSB set corresponds to a first index, the corresponding second index can also be determined by the indicated first index and the correspondence between the first index and the second index; when the first SSB When each SSB in the set corresponds to at least one second index, the corresponding first index may also be determined by the indicated second index and the correspondence between the second index and the first index.

In this embodiment, the first index is, for example, SSB time index (SSB time index) or SSB index (SSB index).

In this embodiment, the second index is, for example, SSB beam index (SSB beam index), SSB index (SSB index) or DRS index (DRS index) or timing offset (timing offset).

In addition, the quasi-co-location relationship between the SSBs in the second SSB set can also be determined through the received indication information. For example, the indication information indicates a quasi-co-location relationship between SSBs in the second SSB set through a fourth index, and SSBs having the same fourth index value are quasi-co-located.

For another example, as in Scheme 1, the first rule means that when the first SSB belongs to a third SSB set, it does not receive downlink signals and/or channels on the first time-frequency resource; when the first SSB belongs to Receiving the downlink signal and/or channel on the first time-frequency resource when the first SSB set does not belong to the third SSB set,

For the content of the third SSB set, please refer to the description in Scheme 1.

Different from solution 1, the third SSB set is semi-statically configured or dynamically configured through the received indication information.

FIG. 14 is another schematic diagram of the data transmission method according to Embodiment 1 of the present invention. As shown in FIG. 14, the method includes:

Step 1401: Receive fifth indication information; the fifth indication information indicates the third SSB set corresponding to the first rule;

Step 1402: Determine to receive the downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and the fifth indication information;

Step 1403: Receive a downlink signal and/or channel on the first time-frequency resource according to the predefined first rule and the fifth indication information.

The fifth indication information may be the above-mentioned first indication information.

In this embodiment, the fifth indication information may be sent through high-layer signaling to perform semi-static configuration.

For example, the high-level signaling is RRC signaling or MAC CE.

In this embodiment, for example, the indication method for semi-static configuration through the fifth indication information may be similar to the method for configuring the second SSB set by the third indication information, and the description will not be repeated here.

In this embodiment, the fifth indication information may also be sent through physical layer signaling for dynamic configuration.

In this way, the network device can dynamically adjust the third SSB set in different COTs or in different transmission windows.

Since the network device needs to access the channel according to the channel detection result, it may not be able to predict the time domain position that can occupy the channel, and sending the first indication information through physical layer signaling can be more flexibly adapted to the dynamic channel access situation.

15 is another schematic diagram of the third SSB set of Embodiment 1 of the present invention. As shown in FIG. 15, the third SSB set is a subset of the second SSB set. On the time axis, after the LBT succeeds, the third information in one or more COTs or one or more transmission windows is indicated by the indication information SSB collection. The indication information is the fifth indication information sent by physical layer signaling. As shown in FIG. 15, the number of SSBs in the third SSB set in different COTs may be different, and the starting position is the same, but it is not limited to this.

16 is another schematic diagram of the third SSB set of Embodiment 1 of the present invention. As shown in FIG. 16, the third SSB set is a subset of the first SSB set, and the second SSB set is a subset of the first SSB set. The third SSB set may include SSBs that do not belong to the second SSB set. In the above, after the LBT succeeds, the third SSB set in one or more COTs or in one or more transmission windows is indicated by the indication information. The indication information is the fifth indication information sent by physical layer signaling. As shown in FIG. 16, the number of SSBs in the third SSB set in different COTs and the time domain positions of the SSBs may be different.

FIG. 17 is another schematic diagram of the third SSB set in Embodiment 1 of the present invention. As shown in FIG. 17, the number of SSBs in the third SSB set in different COTs is the same, and the time domain positions may be different.

In addition, the above FIGS. 15-17 exemplarily show the case where one COT contains the indication information, but the indication may also be made across the COT.

In this embodiment, the priority of the PDCCH sending the fifth indication information is lower than the priority of the SSB in the second SSB set, or the priority of the PDCCH channel or other PDCCH sending the fifth indication information is lower than the first The priority of the SSB in the second SSB set.

The method may further include: sending a confirmation message to the network device that the fifth indication information is received; or, if the fifth indication information is not received, performing a predefined behavior, for example, the UE assumes a second SSB set The SSB in has higher priority.

In the above, the case of receiving downlink signals and/or channels has been described. For the case of sending uplink signals and/or channels, the specific implementation method is similar.

FIG. 18 is another schematic diagram of the data transmission method according to Embodiment 1 of the present invention. As shown in FIG. 18, the method includes:

Step 1801: Send an uplink signal and/or channel on a first time-frequency resource according to the predefined second rule and/or the received second indication information,

As shown in FIG. 18, the method may further include:

Step 1802: Determine to send the uplink signal and/or channel on the first time-frequency resource according to the predefined second rule and/or the second indication information.

In step 1802, determining to receive the downlink signal and/or channel on the first time-frequency resource according to the predefined second rule and/or the second indication information means that, according to the predefined second rule and/or Or, when the second indication information determines whether to receive the downlink signal and/or channel on the first time-frequency resource, the determination result is “Yes”. When the determination result is "No", it is determined that the uplink signal and/or channel is not sent on the first time-frequency resource.

That is, when the priority of the first SSB is higher than the upstream signal and/or channel, the determination is "No", and the upstream signal and/or channel is not sent on the first time-frequency resource; when the first SSB's When the priority is lower than the uplink signal and/or channel, the determination is "Yes", and the uplink signal and/or channel is sent on the first time-frequency resource.

In step 1802, it is determined to send the uplink signal and/or channel on the first time-frequency resource according to the predefined second rule and/or the second indication information.

In this embodiment, when different uplink signals and/or channels are sent, the second rule and/or second indication information may be the same or different.

For example, the second rule means that when the first SSB belongs to a second SSB set, uplink signals and/or channels are not sent on a first time-frequency resource; when the first SSB belongs to the first SSB set, However, when it does not belong to the second SSB set, an uplink signal and/or channel is sent on the first time-frequency resource,

The second SSB set is a subset of the first SSB set, and each SSB in the first SSB set corresponds to different time domain resources of a transmission window.

In this embodiment, the second SSB set corresponding to the first rule and the second SSB set corresponding to the second rule may be the same or different.

For another example, the second rule means that when the first SSB belongs to a third SSB set, uplink signals and/or channels are not sent on the first time-frequency resource; when the first SSB belongs to the first SSB set, However, when it does not belong to the third SSB set, send an uplink signal and/or channel on the first time-frequency resource,

The third SSB set is a subset of the first SSB set, and each SSB in the first SSB set corresponds to a different time domain resource of a transmission window.

In this embodiment, the third SSB set corresponding to the first rule and the third SSB set corresponding to the second rule may be the same or different.

For another example, the second rule means that when the first SSB belongs to a first SSB set, uplink signals and/or channels are not sent on a first time-frequency resource; when the first SSB does not belong to the first SSB During assembly, the uplink signal and/or channel is sent on the first time-frequency resource, and the time domain positions of the two SSBs in the first SSB set overlap

In this embodiment, the first SSB set corresponding to the first rule and the first SSB set corresponding to the second rule may be the same or different.

Similar to receiving downlink signals and/or channels, the method may further include:

Receiving the second indication information, where the second indication information indicates that the uplink signal and/or channel is sent on the first time-frequency resource.

Similar to the first indication information, the second indication information may be sent through higher layer signaling or physical layer signaling.

Receive fourth indication information indicating the second SSB set corresponding to the second rule.

The fourth indication information may be the above-mentioned second indication information.

Receiving sixth indication information indicating the third SSB set corresponding to the second rule.

The sixth indication information may be the above-mentioned second indication information.

Similar to the third indication information and the fifth indication information, the fourth indication information and the sixth indication information may be sent through higher layer signaling or physical layer signaling.

In this embodiment, the specific method for sending the uplink signal and/or channel on the first time-frequency resource and the method for receiving the uplink signal and/or channel are determined according to the predefined second rule and/or the second indication information The situation is similar and will not be repeated here.

In this embodiment, for example, in an unlicensed band, the SSB may also be sent as part of the DRS. In this case, there is a one-to-one correspondence between DRS and SSB.

For example, in this case, the transmission window may be a DRS transmission window, and the second index may be a DRS index.

That is to say, one DRS contains one SSB, and in addition, one DRS can also contain at least one remaining minimum system information (Remaining Minimum System Information, RMSI). At this time, the SSB in the DRS corresponds to the RMSI one by one.

When the SSB is included in the DRS and sent, the above method described for the SSB is also applicable to the DRS, and the description will not be repeated here.

It can be seen from the above embodiments that, through predefined rules and/or received indication information, other signals and/or channels other than SSB can be sent or received on time-frequency resources that overlap with time-frequency resources corresponding to the SSB. It is necessary to send and receive other signals and/or channels on the time-frequency resources corresponding to the SSB, so as to effectively improve resource utilization.

In addition, when step 1901 and step 1902 are both executed at different times, the first time-frequency resources used in step 1901 and step 1902 are different.

Unlike the UE side, the priority between the downlink signals and/or channels or the uplink signals and/or channels other than SSB and SSB is controlled by the network device, therefore, on the network device side, priority is not required determine.
