     TECHNICAL FIELD 
     The present disclosure relates to communications and, specifically, to a method and device for determining time-frequency resources. 
     BACKGROUND 
     In the related art, in a new radio (NR) system, it has been determined currently that a base station can semi-statically configure some resource sets. Resources in these resource sets can be dynamically multiplexed to a physical downlink shared channel (PDSCH) transmission, and specifically resources of which resource sets can be multiplexed to the PDSCH transmission is indicated through dynamic signaling. 
     In the related art, in a physical downlink control channel (PDSCH) of a Long Term Evolution (LTE) system, a frequency domain will be mapped to a full bandwidth, and the number of orthogonal frequency division multiplexing (OFDM) symbols occupied by the PDCCH in a time domain is indicated through a physical control format indicator channel (PCFICH). Therefore, a PDCCH domain is a frequency domain full bandwidth, the time domain occupies a structure of several OFDM symbols in front of a sub-frame, time-frequency resources of the PDCCH domain are completely separated from time-frequency resources of the PDSCH domain, and resources in the PDCCH domain cannot be used for the PDSCH transmission. 
     In an LTE enhanced PDCCH (ePDCCH), the ePDCCH is transmitted on a physical resource block (PRB) set, that is, the ePDCCH and the PDSCH adopt a frequency division multiplexing mode. Resources in the PRB set are not used for the ePDCCH transmission but still can be used for the PDSCH transmission, and a “Resource Block assignment” domain in downlink control information (DCI) may include an indication for this part of resources, so that a terminal may know allocation of all resources for the PDSCH transmission. 
     For an NR PDCCH, based on several current discussions of 3GPP RAN1 conferences, the design will be performed based on a control resource set (referred to as CORESET for short). Different from a characteristic of full bandwidth distribution in the LTE PDCCH, the distribution of downlink control channels in the NR is limited by CORESET(s) configured by the system, the CORESET is semi-statically configured while user scheduling itself is dynamically changed, so when idle resources remain in the CORESET, in order to avoid resource waste, these resources can be used for the PDSCH transmission. Therefore, how to indicate multiplexed CORESET resources to a user to let the user know that there is a PDSCH service on these control resources is a problem to be solved. 
     Furthermore, the 3GPP RAN1 has approved that the base station semi-statically configures several resource sets to dynamically indicate whether resources in the resource set can be multiplexed to the scheduled PDSCH transmission or whether the scheduled PDSCH transmission needs to perform rate matching on part of resources of the resource set. 
     No efficient solution has been provided to solve the problem in the related art of how to indicate time-frequency resources used by the PDSCH transmission.

     Through the above steps, the first communication node determines the information about the first resource set for the second communication node; the information is transmitted to the second communication node after the above information is determined, and the second communication node determines time-frequency resources used during the PDSCH transmission according to the information. The above technical solution resolves the problem in the related art of how to indicate time-frequency resources used during the PDSCH transmission, implementing the indication of the time-frequency resources used during the PDSCH transmission to a user.

     The present disclosure will be described below in conjunction with exemplary embodiments. 
     Embodiment One 
     The base station semi-statically configures multiple resource sets for the terminal and may configure the multiple resource sets through RRC signaling. Time-frequency resources of the multiple configured resource sets do not overlap. 
     When the base station configures resource sets for the terminal, the base station needs to configure time-frequency resources occupied by the resource sets in a time-frequency resource unit, and also needs to configure time-frequency resource units in which the resource sets appear or time-frequency resource units in which the terminal monitors the resource sets. The time domain configuration in the time-frequency unit may be configured through at least one of the following: a period, a time unit offset and a time unit pattern. The frequency domain configuration of the time-frequency resource unit may be configured through at least one of the following: a carrier, a bandwidth part (BWP) in the carrier, several RBGs on the BWP in the carrier and several PRBs on the BWP in the carrier. 
     If the base station does not configure the time-frequency resource unit in which the resource sets appear, the terminal may consider that the resource sets appear in each time-frequency resource unit, or the terminal needs to monitor the resource sets in all time-frequency resource units. 
     Embodiment Two 
     The base station semi-statically configures multiple resource sets for the terminal and may configure the multiple resource sets through RRC signaling. Time-frequency resources of the multiple configured resource sets may overlap. The overlap herein may be partial overlap, or may be complete overlap.  FIG.  2    is a schematic diagram of partial overlap or complete overlap according to an exemplary embodiment. As shown in  FIG.  2   , from left to right, complete overlap, partial overlap and complete overlap are shown respectively. 
     When the base station configures the resource sets, the base station may indicate a priority of each resource set or priorities of resource sets where resources overlap in an explicit or implicit manner. 
     As an example, the explicit manner may be to pre-configure by a system or semi-statically configure a priority sequence number x of the resource set, where x is an integer, and priority sequence numbers from small to large indicate that priorities are from high to low, or priority sequence numbers from large to small indicate that priorities are from high to low. 
     In another example, the explicit manner may be to pre-configure by a system or semi-statically configure resource sets meeting a characteristic  1  as high priorities and remaining resource sets failing to the characteristic  1  as low priorities. 
     The characteristic  1  may be, but is not limited to, one of the following: a resource set containing all or part of time-frequency resources meeting a characteristic  2 ; and a resource set whose configuration manner meets a characteristic  3 . 
     The characteristic  2  may be, but is not limited to, one of the following: being a specific or dedicated time-frequency resource, such as a time-frequency resource occupied by a certain reference signal (RS), which for example, may be a synchronizing signal, a channel state indication-RS (CSI-RS), a sounding reference signal (SRS), a demodulation reference signal (DMRS), a phase tracking reference signal (PTRS), etc., and a time-frequency resource occupied by a certain public channel, which for example, may be a physical broadcast channel (PBCH), a channel bearing system information, etc.; and being a reservation resource. 
     The characteristic  3  may be, but is not limited to, one of the following: containing a certain configuration granularity, such as resource element (RE)-level configuration granularity and a resource block (RB)-level configuration granularity; configuration signaling being a certain specific format; and configuration signaling being a certain specific length or greater than a certain length. 
     The implicit manner may be that a resource set index itself represents a priority sequence, the resource set indexes from low to high represent that priorities are from high to low, or the resource set indexes from high to low represent that priorities are from high to low. 
     When the dynamic signaling indicates whether a PDSCH resource needs to perform rate matching on the resource set or part of resources of the resource set, for multiple resource sets where resources overlap, if dynamic signaling indications of the multiple resource sets are consistent, that is, their dynamic signaling indications all indicate that rate matching needs to be performed or the rate matching does not need to be performed, the rate matching of the PDSCH is performed according to the dynamic signaling indications; and if their dynamic signaling indications are inconsistent, rate matching needs to be performed on some resource sets or part of resources thereof, and rate matching does not need to be performed on some resource sets or part of resources thereof, which is determined according to indications of the resource sets with high priority or part of resources thereof. Whether rate matching needs to be performed is determined based on the indication of the resource sets with high priority or part of resources thereof. 
     Embodiment Three 
     The base station semi-statically configures multiple resource sets for the terminal and may configure the multiple resource sets through RRC signaling. 
     The base station sends a dynamic signaling indication to the terminal to indicate a PDSCH transmission corresponding to a certain scheduling, resources of which resource sets may be occupied by the overlapped PDSCH, that is, rate matching does not need to be performed, and resources of which resource sets cannot be occupied by the PDSCH, that is, rate matching needs to be performed. 
     For multiple resource sets where resources overlap, if dynamic signaling indications are different, then for the overlap area, as long as the dynamic signaling indication of at least one of resource sets indicates that rate matching does not need to be performed, rate matching of the PDSCH does not need to be performed on the overlap area. Only when dynamic signaling indications of all resource sets where overlapping occurs indicate that rate matching needs to be performed, rate matching of the PDSCH needs to be performed on the overlap area. 
     If a dynamic signaling indication corresponding to a certain resource set being set to “1” indicates that rate matching does not need to be performed and the dynamic signaling indication being set to “0” indicates that rate matching needs to be performed, for the overlap area of multiple resource sets, a OR operation is performed according to the dynamic signaling indication of each resource set which belongs to the overlap area, and whether resource multiplexing or rate matching needs to be performed on the overlap area is determined according to results of the OR operation: if the result of the OR operation is “1”, rate matching does not need to be performed on the overlap area, and if the result of the OR operation is “0”, rate matching needs to be performed on the overlap area. 
     If a dynamic signaling indication corresponding to a certain resource set being set to “1” indicates that rate matching needs to be performed and the dynamic signaling indication being set to “0” indicates that rate matching does not need to be performed, for the overlap area of multiple resource sets, an AND operation is performed according to the dynamic signaling indication of each resource set which belongs to the overlap area, and whether resource multiplexing or rate matching needs to be performed on the overlap area is determined according to results of the AND operation: if the result of the AND operation is “0”, rate matching does not need to be performed on the overlap area, and if the result of the AND operation is “1”, rate matching needs to be performed on the overlap area. 
     In this embodiment,  FIG.  3    is a schematic diagram of a dynamic indication manner according to an exemplary embodiment of the present disclosure. As shown in  FIG.  3   , a black block in Resource set  1  denotes a PDCCH scheduling the PDSCH. For a PDCCH resource scheduling the PDSCH, regardless of whether the PDSCH needs to perform rate matching on other resources of a resource set where the PDCCH resource is located, the PDSCH needs to perform rate matching around time-frequency resources occupied by the PDCCH scheduling the PDSCH. In addition, if the terminal blindly detects a common PDCCH or a group-common PDCCH in a certain resource set, regardless of whether the PDSCH needs to perform rate matching on the resource set, the PDSCH needs to perform rate matching around time-frequency resources occupied by at least one of the common PDCCH and the group-common PDCCH. 
     Embodiment Four 
     The base station semi-statically configures multiple resource sets for the terminal and may configure the multiple resource sets through RRC signaling. 
     The base station sends a dynamic signaling indication to the terminal to indicate a PDSCH transmission corresponding to a certain scheduling, resources of which resource sets may be occupied by the overlapped PDSCH, that is, rate matching does not need to be performed, and resources of which resource sets cannot be occupied by the PDSCH, that is, rate matching needs to be performed. The dynamic signaling indication may be valid on part of OFDM symbols of one slot. 
       FIG.  4    is a schematic diagram according to an embodiment 4. As shown in  FIG.  4   , a PDCCH scheduling the PDSCH is sent in Resource set  1 , and a dynamic signaling indication indicating whether the PDSCH multiplexes resources of the semi-statically configured resource sets is sent in this PDCCH or another PDCCH. Assuming that the dynamic signaling indication for Resource set  1  is “1”, which indicates that all or part of time-frequency resources of Resource set  1  may be multiplexed by the PDSCH, the PDSCH does not need to perform rate matching on all or part of time-frequency resources of Resource set  1 . When a dynamic signaling indication of Resource set  2  is “0”, which indicates that all or part of time-frequency resources of Resource set  2  may not be multiplexed by the PDSCH, the PDSCH needs to perform rate matching on all or part of time-frequency resources of Resource set  2 . 
     Resource set  1  and Resource set  2  have their own monitor occasion configuration. The monitor occasion configuration of Resource set  1  is in a slot level. For example, each slot needs to be monitored or each several slots need to be monitored. One slot only has one monitor occasion at most. The monitor occasion configuration of Resource set  2  is in a min-slot level or an OFDM symbol level, and one slot may have multiple monitor occasions. 
     The dynamic signaling indications of Resource set  1  and Resource set  2  are valid on only one monitor occasion. For example, the monitor occasion may be a first monitor occasion where Resource set  1 , Resource set  2  and resource allocation of the PDSCH overlap in a slot where a PDSCH transmission corresponding to the dynamic signaling indication is located. Using  FIG.  4    as an example, for Resource set  1 , the valid monitor occasion is Occasion  1  of Resource set  1 , and for Resource set  2 , the valid monitor occasion is Occasion  1  of Resource set  2 . 
     Embodiment Five 
     Still using  FIG.  4    as an example, in a corresponding resource set, the dynamic signaling indications of Resource set  1  and Resource set  2  are valid on all monitor occasions which overlap resource allocation of a corresponding PDSCH. For example, the all monitor occasions may be all monitor occasions where Resource set  1 , Resource set  2  and resource allocation of the PDSCH overlap in a slot where a PDSCH transmission corresponding to the dynamic signaling indication is located. Using  FIG.  4    as an example, for Resource set  1 , the valid monitor occasion is Occasion  1  of Resource set  1 , and for Resource set  2 , the valid monitor occasion is Occasion  1  and Occasion  2  of Resource set  2 . 
     Embodiment Six 
       FIG.  5    is a schematic diagram according to an embodiment 6. As shown in  FIG.  5   , in a corresponding resource set, the dynamic signaling indications of Resource set  1  and Resource set  2  are valid on all monitor occasions which overlap resource allocation of a corresponding PDSCH. A PDCCH domain usually is first several OFDM symbols of one slot. In the PDCCH domain, dynamic signaling indications are valid on all monitor occasions where Resource set  1 , Resource set  2  and resource allocation of the PDSCH overlap. Using  FIG.  5    as an example, for Resource set  1 , the valid monitor occasion is Occasion  1  of Resource set  1 , and for Resource set  2 , the valid monitor occasion is Occasion  1  and Occasion  2  of Resource set  2 . Occasion  3  also overlaps resource allocation of the PDSCH, but since Occasion  3  is not within the PDCCH domain, the dynamic signaling indication is not valid in Occasion  3  of Resource set  2 . 
     Embodiment Seven 
     Still using  FIG.  4    as an example, for the dynamic signaling indications of Resource set  1  and Resource set  2 , their valid ranges are related to the blind detection of the terminal. For example, in a corresponding resource set, the dynamic signaling indications are valid on a first monitor occasion which overlaps resource allocation of a corresponding PDSCH. In  FIG.  4   , the first monitor occasion in Resource set  1  is Occasion  1 , and the first monitor occasion in Resource set  2  is Occasion  1 . For other monitor occasions which overlap resource allocation of the PDSCH, for example, Occasion  2  of Resource set  2  in  FIG.  4   , whether the dynamic signaling indication is valid depends on results of the blind detection performed by the terminal on the resource set in a corresponding monitor occasion. 
     The blind detection includes the following. 
     1) If the terminal does not blindly detect a PDCCH sent by the base station to the terminal itself on a corresponding occasion, 
     time-frequency resources of a corresponding resource set on this occasion, which overlap resource allocation of a corresponding PDSCH, may be used for the PDSCH transmission, that is, the terminal does not need to perform rate matching on the PDSCH in corresponding time-frequency resources, which is not related to the dynamic signaling indication; or the indication of the dynamic signaling indication for this resource set continues to be valid. 
     2) If the terminal detects the PDCCH sent by the base station to the terminal itself on a corresponding occasion, 
     a corresponding resource set cannot be used for the PDSCH transmission on this occasion, that is, the terminal needs to perform rate matching on the PDSCH in corresponding time-frequency resources, which is not related to the dynamic signaling indication. 
     Alternatively, in the corresponding resource set on this occasion, when the terminal blindly detects resources other than time-frequency resources occupied by the PDCCH, the indication of the dynamic signaling indication for this resource set continues to be valid. 
     Embodiment Eight 
     Using  FIG.  5    as an example, for the dynamic signaling indications of Resource set  1  and Resource set  2 , their valid ranges are related to the blind detection of the terminal. For example, in a corresponding resource set, the dynamic signaling indication is valid on all monitor occasions which overlap resource allocation of a corresponding PDSCH. In  FIG.  5   , the valid monitor occasion in Resource set  1  is Occasion  1 , and the valid monitor occasion in Resource set  2  is Occasion  1  and Occasion  2 . For other monitor occasions which overlap resource allocation of the PDSCH, for example, Occasion  3  of Resource set  2  in  FIG.  5   , whether the dynamic signaling indication is valid depends on results of the blind detection performed by the terminal on the resource set on a corresponding monitor occasion. 
     The result of the blind detection is as follows. 
     1) If the terminal does not blindly detect a PDCCH sent by the base station to the terminal itself on a corresponding occasion, 
     time-frequency resources of a corresponding resource set on this occasion, which overlap resource allocation of a corresponding PDSCH, may be used for the PDSCH transmission, that is, the terminal does not need to perform rate matching on the PDSCH in corresponding time-frequency resources, which is not related to the dynamic signaling indication; or the indication of the dynamic signaling indication for this resource set continues to be valid. 
     2) If the terminal detects the PDCCH sent by the base station to the terminal itself on a corresponding occasion, 
     a corresponding resource set cannot be used for the PDSCH transmission on this occasion, that is, the terminal needs to perform rate matching on the PDSCH in corresponding time-frequency resources, which is not related to the dynamic signaling indication. 
     Alternatively, in the corresponding resource set on this occasion, when the terminal blindly detects resources other than time-frequency resources occupied by the PDCCH, the indication of the dynamic signaling indication for this resource set continues to be valid.

       FIG.  6    is a schematic diagram according to an embodiment 9. As shown in  FIG.  6   , when a PDSCH scheduled in Resource set  1  occupies multiple slots, a multiplexing resource dynamic signaling indication which is sent by the base station to the terminal and corresponds to the PDSCH transmission is only valid in a first slot of resource allocation of the PDSCH, and is invalid in other slots of resource allocation of the PDSCH, that is, in  FIG.  5   , the dynamic signaling indication of Resource set  1  and Resource set  2  are only valid in Slot  1  and invalid in Slot  2 . 
     Embodiment Ten 
     As shown in  FIG.  6   , when the PDSCH scheduled in Resource set  1  occupies multiple slots, a multiplexing resource dynamic signaling indication which is sent by the base station to the terminal and corresponds to the PDSCH transmission is valid in all slots included in resource allocation of the PDSCH, that is, in  FIG.  5   , the dynamic signaling indication of Resource set  1  and Resource set  2  are valid in both Slot  1  and Slot  2 . 
     Embodiment Eleven 
     As shown in  FIG.  6   , when the PDSCH scheduled in Resource set  1  occupies multiple slots, a multiplexing resource dynamic signaling indication which is sent by the base station to the terminal and corresponds to the PDSCH transmission is valid in a first slot of resource allocation of the PDSCH, that is, this indication is valid in Slot  1  in  FIG.  5   ; for other slots included in resource allocation of the PDSCH, that is, Slot  2  in  FIG.  5   , dynamic signaling  2  is required to be indicate. According to the indication of the dynamic singling  2 , whether a corresponding resource set in Slot  2  may be multiplexed the PDSCH scheduled in Resource set  1  is determined. The dynamic singling  2  may be one of the following: 
     an indication indicating activation/inactivation of a dynamic signaling indication sent in Slot  1 ; and 
     a new dynamic signaling indication, which is not related to the dynamic signaling indication sent in Slot  1 , where an indicated resource set may be different from the dynamic signaling indication sent in Slot  1 . 
     Embodiment Twelve 
     When a gNB configures time-frequency resources of a resource set, if one resource set contains multiple CORESETs, monitor occasions of the multiple CORESETs configured in the same resource set should meet a certain requirement. The requirement may be one or a more of the following: 
     1) a monitor occasion configuration of each CORESET is totally the same, that is, the CORESET is blindly detected on the same radio frame or sub-frame or slot or OFDM symbol; 
     2) a monitor occasion configuration level of each CORESET is the same and is a slot level, for example, the CORESET may be blindly detected on each slot or every multiple slots; 
     3) a monitor occasion configuration level of each CORESET is the same and is a mini-slot level, for example, the CORESET may be blindly detected on each mini-slot or every multiple mini-slots; 
     4) a monitor occasion configuration level of each CORESET is the same and is an OFDM symbol level, for example, the CORESET may be blindly detected on each OFDM symbol or every multiple OFDM symbols; and 
     5) a monitor occasion configuration of each CORESET needs to meet an inclusion relationship, for example, for a CORESET with a sparse number of times of blind detections and a CORESET with an intensive number of times of blind detections, blind detection moment of the former is a subset of blind detection moment of the latter. As shown in  FIG.  7   , CORESET  1  and CORESET  4  are configured in the same resource set, and since the monitor occasion of CORESET  1  is each slot while the monitor occasion of CORESET  4  is each odd slot, the monitor occasion of CORESET  4  is a sub-set of the monitor occasion of CORESET  1 . CORESET  2  and CORESET  3  may be configured in the same resource set, and since the monitor occasion of CORESET  2  is OFDM symbols {0 2 5 12} of each slot while the monitor occasion of CORESET  3  is an OFDM symbol {5} of each slot, the monitor occasion of CORESET  3  is a sub-set of the monitor occasion of CORESET  2 . 
     The number of times of appearance of the monitor occasion configuration of each CORESET in a fixed time unit is the same. For example, with one slot as the fixed time unit, CORESETs whose monitor occasion appears once in one slot may be configured in the same resource set. As shown in  FIG.  7   , CORESET  1  and CORESET  3  may be configured in the same resource set, because their monitor occasion appears once in one slot. 
     After a resource set containing multiple CORESETs is configured according to the above rule, a dynamic signaling indication for this resource set is valid in corresponding unit time, where the unit time may be a sub-frame or multiple sub-frames, or a slot or multiple slots, or a PDCCH domain of one slot or PDCCH domains of multiple slots, or a fixed number of OFDM symbols. In time-frequency resources which overlap resource allocation of the PDSCH, all monitor occasions of all CORESETs included in the resource set in the unit time follow the dynamic signaling indication. 
     Alternatively, after one resource set containing multiple CORESETs is configured according to the above rule, the dynamic signaling indication for this resource set is valid on a single monitor occasion. The single monitor occasion may be time-frequency resources corresponding to a first monitor occasion of each CORESET included in this resource set in time-frequency resources where the resource set overlaps resource allocation of the PDSCH. 
     Embodiment Thirteen 
     The base station semi-statically configures multiple resource sets for the terminal and may configure the multiple resource sets through RRC signaling. 
     The base station sends a dynamic signaling indication to the terminal to indicate a PDSCH transmission corresponding to a certain scheduling, resources of which resource sets may be occupied by the overlapped PDSCH, that is, rate matching does not need to be performed, and resources of which resource sets cannot be occupied by the PDSCH, that is, rate matching needs to be performed. 
     For the overlap area of multiple resource sets, the base station may configure a principle to determine whether the scheduled PDSCH transmission performs rate matching on the overlap area. The principle may be configured through RRC signaling or system information semi-statically or through the PDCCH dynamically. 
     For the overlap area of multiple resource sets, different principles may be adopted to determine whether the scheduled PDSCH transmission performs rate matching on the overlap area. For example, for different configuration manners or a resource set containing different types of time-frequency resources, different principles may be adopted.  FIG.  8    is a schematic diagram  1  according to an embodiment thirteen. As shown in  FIG.  8   , when Resource set  1  and Resource set  2  are configured in a configuration manner  1  or configured as resource sets containing the type  1  of time-frequency resources and Resource set  3  is configured in a configuration manner  2  or configured as a resource set containing the type  2  of time-frequency resources, for an overlap area OA 1  of Resource set  1  and Resource set  2 , whether the PDSCH needs to perform rate matching on OA 1  is determined according a principle  1 , and for an overlap area OA 2  of Resource set  1  and Resource set  3 , whether the PDSCH needs to perform rate matching on OA 2  is determined according a principle  2 . 
     The principle  1  and the principle  2  may be one of the following. 
     1) In resource sets where overlapping occurs, as long as one resource set is indicated by the dynamic singling indication to be unable to be multiplexed by the PDSCH, the PDSCH needs to perform rate matching on the resource sets, and regardless of whether the PDSCH needs to perform rate matching on other resource sets, the overlap area cannot be multiplexed by the PDSCH, and the PDSCH needs to perform rate matching on the overlap area. 
     2) In resource sets where overlapping occurs, as long as one resource set is indicated by the dynamic singling indication to be able to be multiplexed by the PDSCH, the PDSCH does not need to perform rate matching on the resource sets, and regardless of whether the PDSCH needs to perform rate matching on other resource sets, the overlap area can be multiplexed by the PDSCH, and the PDSCH does not need to perform rate matching on the overlap area. 
     3) According to resource set priorities semi-statically configured or pre-configured by a system or resource set priorities which are equivalent to priorities semi-statically configured or pre-configured by the system, when a resource set having a high priority overlaps a resource set having a low priority, a dynamic signaling indication of the resource set having a high priority is followed to determine whether the overlap area can be multiplexed by the PDSCH and whether the PDSCH needs to perform rate matching on the overlap area. 
     Embodiment Fourteen 
     The dynamic singling indication may contain one or more bits for indicating whether one or more resource set time-frequency resources can be used by the scheduled PDSCH transmission or whether the scheduled PDSCH transmission needs to perform rate matching on resource set time-frequency resources. The resource set indicated by a certain one or multiple bits in the dynamic signaling indication may be semi-statically configured, or may be dynamically changed. 
       FIG.  9    is a schematic diagram  1  according to an embodiment fourteen. As shown in  FIG.  9   , when the resource set is configured semi-statically, the base station may configure an x-th bit or bit group in dynamic signaling indications corresponding to Resource  1  and Resource  2  and configure a y-th bit or bit group in a dynamic signaling indication corresponding to Resource set  3  through RRC signaling or system information, where x and y are positive integers not greater than a length of the dynamic signaling indication. In one slot, time-frequency resources corresponding to Resource set  1  and Resource set  2  may be the same or different, and may be semi-statically configured by the base station through RRC signaling or system information. At least one of the following parameters of Resource set  1  and Resource set  2  is different: a configuration period, a time domain offset and a monitor occasion, and these parameters may also be semi-statically configured by the base station through RRC signaling or system information. Therefore, the base station, through RRC signaling or system information, may semi-statically configure a time unit appearing in Resource set  1 , the x-th bit or bit group corresponding to Resource set  1  in the dynamic signaling indication, a time unit appearing in Resource set  2 , the x-th bit or bit group corresponding to Resource set  2  in the dynamic signaling indication, and the y-th bit or bit group corresponding to Resource set  3  in the dynamic signaling indication. 
     As shown in  FIG.  9   , when the resource set is configured dynamically, the base station may configure an x-th bit or bit group in dynamic signaling indications corresponding to Resource  1  and Resource  2  and configure a y-th bit or bit group in a dynamic signaling indication corresponding to Resource set  3  through RRC signaling or system information, where x and y are positive integers not greater than a length of the dynamic signaling indication. In one slot, time-frequency resources corresponding to Resource set  1  and Resource set  2  may be the same or different, and may be semi-statically configured by the base station through RRC signaling or system information. At least one of the following parameters of Resource set  1  and Resource set  2  is different: a configuration period, a time domain offset and a monitor occasion, and these parameters may also be semi-statically configured by the base station through RRC signaling or system information. According to the configuration of the base station, when the terminal may determine that only Resource set  1  or Resource set  2  exists in a certain time unit scheduled by the PDSCH (which may be a sub-frame or a slot or a mini-slot or an OFDM symbol group), the resource set corresponding to the x-th bit or bit group may be Resource set  1  or Resource set  2 , and the y-th bit or bit group in the dynamic signaling set always corresponds to Resource set  3 . 
     Configurations of Resource set  1  and Resource set  2  may also be shown in  FIG.  10   .  FIG.  10    is a schematic diagram  2  according to an embodiment fourteen. The x-th bit or bit group in the dynamic signaling indication corresponds to Resource set  1  in some time units (such as slots  1 ,  3  and  5 ) or corresponds to Resource set  1  and Resource set  2  in some time units (such as slots  2 ,  4  and  6 ), that is, a resource set index as well as the number of resource sets corresponding to the x-th bit or bit group may be different, and may also be semi-statically configured or determined by the terminal according to the configuration of the resource set. 
     Embodiment Fifteen 
     When the base station configures a length of dynamic signaling to be m bits and configures the number of candidate multiplexed resource sets that the dynamic signaling needs to indicate to be m+1, which resource set the m bits of the dynamic signaling correspond to depends on a resource set stored in a certain time unit and a resource set which overlaps resource allocation for the scheduled PDSCH transmission. 
     Using m=2 as an example, the length of the dynamic signaling is 2 bits, and the number of candidate multiplexed resource sets is 3, which are marked as Resource set  1 , Resource set  2  and Resource set  3  respectively. 
     If these three resource sets exist in a certain time unit and all overlap resource allocation of the PDSCH transmission scheduled by the current time unit, one of the following manners or a combination thereof is adopted. 
     According to a sequence order or priority order of the resource sets, 2-bit dynamic signaling cannot indicate the multiplexing of the last resource set, that is, the terminal considers by default that the last resource set cannot be multiplexed by the PDSCH and the PDSCH needs to perform rate matching on the last resource set. 
     According to a sequence order or priority order of the resource sets, 1 bit in the dynamic signaling indication is used for jointly indicating the multiplexing of last two resource sets, that is, both the last two resource sets are multiplexed or the both are not multiplexed. 
     If in a certain time unit, the number of resource sets that overlap resource allocation of the PDSCH transmission scheduled by the current time unit is 2, 2 bits of the dynamic signaling indicate the two resource sets respectively. 
     If in a certain time unit, the number of resource sets that overlap resource allocation of the PDSCH transmission scheduled by the current time unit is less than 2, for example, 1, redundant bits exist in the dynamic indication signaling. 
     Embodiment Sixteen 
     When there is redundancy in the number of bits contained in dynamic indication signaling transmitted by a certain time unit compared to the number of resources sets that the current time unit needs to indicate, redundant bits may have one of functions or a combination thereof. 
     The redundant bits are used for indicating multiplexing or rate matching after at least one of a time domain, a frequency domain and a space domain of a resource set corresponding to an adjacent bit or bit group is split. 
     The redundant bits are used for indicating multiplexing or rate matching after at least one of a time domain, a frequency domain and a space domain of a specific resource set is split. The specific resource set may be a resource set that the terminal needs to monitor, or a resource set of a PDCCH receiving the scheduled PDSCH transmission, or a resource set sent by the dynamic signaling indication, or a specific resource set semi-statically configured by the base station. 
     The redundant bits are used for indicating multiplexing or rate matching after at least one of a time domain, a frequency domain and a space domain of every other resource set corresponding to all other adjacent bits or bit groups is split. 
     The redundant bits are used for indicating whether activation and deactivation or handover of a carrier or a BWP occur in a subsequent time unit. The split is that at least one of a time domain, a frequency domain and a space domain of a corresponding resource set is equally split and may be equally split into n part according to the number of redundant bits, where n is a positive integer, and after the equal split is performed, non-redundant bits and redundant bits jointly indicate which equally split parts of the corresponding resource set are capable of being multiplexed to the PDSCH transmission, or the PDSCH does not need to perform rate matching on which equally split parts. 
     The redundant bits are used for indicating whether a length of a dynamic signaling indication sent by a subsequent time unit changes. For example, a state ‘0’ represents that the length does not change, and a state ‘1’ represents that the length changes. For example, the length is recued or increased by z bits, where z may be equal to, but is not limited to, the number of redundant bits or 1. 
     Embodiment Seventeen 
     The base station configures one or more resource sets for the terminal, where some resource sets are configured to contain one or more complete or partial CORESETs while configurations of other resource sets are not related to the CORESET, or although specific time-frequency resources overlap the CORESET, the base station does not configure resource sets with specific CORESET sequences, but directly configures specific time-frequency resources contained in the resource sets in an explicit manner. During configuring, at least one of following resources may be configured: time domain resources contained in a time domain resource unit, frequency domain resources contained in a frequency domain resource unit, a period and offset of a time domain resource unit in a time domain, and a period and offset of a frequency domain resource unit in a frequency domain. 
     For example, the time domain resource unit may be a slot or a sub-frame, and the base station configures a certain resource set for occupying part of OFDM symbols of the slot or sub-frame in a time domain resource unit. 
     The frequency domain resource unit may be N PRBs, for example, 25 or 50 PRBs, and the base station configures a certain resource set for occupying part of PRBs of the N PRBs in a frequency domain resource unit. 
     The period of the time domain resource unit in the time domain may be one or more time domain resource units. For example, if the period is configured as 2 slots, it means that in every 2 slots, part of OFDM symbols of one slot is time domain resources of the resource set. The offset of the time domain resource unit in the time domain represents that time domain resources of the resource set exist in a time domain resource unit (which one time domain resource depends to a value of the offset) in a time domain period. If the offset is set to 1, it means that part of OFDM symbols of a first time domain resource unit in each time domain period is time domain resources of the resource set. 
     The period of the frequency domain resource unit in the frequency domain may be one or more frequency domain resource units, and may be limited to be one or more carried bandwidths or one or more BWPs of one carrier bandwidth. For example, if the period is set to 2 frequency domain resource units, it means that in every 2 frequency domain resource units, part of PRBs of one frequency domain resource unit is frequency domain resources of the resource set. The offset of the frequency domain resource unit in the frequency domain represents that frequency domain resources of the resource set exist in a frequency domain resource unit (which one frequency domain resource unit depends on a value of the offset) in one frequency domain period. If the offset is set to 1, it means that part of PRBs of a first frequency domain resource unit in each frequency domain period is frequency domain resources of the resource set. 
       FIG.  11    is a flowchart of another method for configuring a first resource set according to an embodiment seventeen. As shown in  FIG.  11   ,  FIG.  11    shows a graphical representation of the above description. 
     From the above description of embodiments, it will be apparent to those skilled in the art that the method in the embodiments described above may be implemented by software plus a necessary general-purpose hardware platform, or may of course be implemented by hardware. However, in many cases, the former is a preferred implementation mode. Based on this understanding, the solutions provided by the present disclosure substantially, or the part contributing to the related art, may be embodied in the form of a software product. The computer software product is stored in a storage medium (such as a read-only memory (ROM)/random access memory (RAM), a magnetic disk or an optical disk) and includes several instructions for enabling a terminal device (which may be a mobile phone, a computer, a server, a network device, or the like) to execute the methods according to each embodiment of the present disclosure.

     This embodiment further provides a device for determining time-frequency resources for implementing the above-mentioned embodiments and preferred embodiments. What has been described will not be repeated. As used below, the term “module” may be software, hardware or a combination thereof capable of implementing predetermined functions. The apparatus described in the following embodiment is preferably implemented by software, but implementation by hardware or a combination of software and hardware is also possible and conceived.

     The transmission module is configured to transmit the information to the second communication node, where the PDSCH transmission includes a process in which data is transmitted to the second communication node through a PDSCH, and the PUSCH transmission includes a process in which the second communication node transmits data to the first communication node through a PUSCH.

     Optionally, when the first determination module configures multiple first resource sets for the second communication node, the first determination module configures priorities for part or all of the multiple first resource sets. 
     Optionally, when time-frequency resources of the multiple first resource sets overlap, whether the overlapped time-frequency resources are allowed to be multiplexed to the PDSCH transmission or whether the PDSCH transmission needs to perform rate matching around the overlapped time-frequency resources is determined through following manner: the determination is made according to a dynamic signaling indication of a first resource set having a higher priority. 
     Optionally, the first resource set for the second communication node includes one of the following: part of time domain resources in a time domain resource unit are configured as the first resource set; and part of frequency domain resources in a frequency domain resource unit are configured as the first resource set.
