The DCI is used to indicate descending scheduling resource, and for convenience, the resource of DCI scheduling is referred to as target dispatch money Source.The target dispatch resource may include multigroup (M groups) scheduling resource.Wherein, include at least one resource per group scheduling resource Block RB or resource block group RBG.For example, when the DCI be DCI format 2D, and the domains RA resource distribution mode be type 0 when, target The unit of scheduling resource is RBG, includes integral multiple RBG per group scheduling resource.For another example, when the DCI be DCI format 2D, and When the domains RA resource distribution mode is Class1, the unit of target dispatch resource can be RB, include integral multiple per group scheduling resource RB.In resource impact, RB can be expressed as PRB (Physical RB, physics RB), can also be virtual RB (virtual RB, VRB), wherein VRB includes centralization VRB and virtual reality B.The application for convenience, by a variety of projected forms of RB It is referred to as RB.Likewise, the RB in RBG is also not limited to certain RB form (being such as not limited to VRB or PRB), RB includes more The possible RB forms of kind.
This state multigroup scheduling resource correspond to the non-co-located QCL of standard M groups antenna port (for example, be denoted as antenna port group #1 and Antenna port group #2), every group of antenna port includes at least one antenna port.For example, the multigroup scheduling resource (for example, It is denoted as scheduling resource #1 and is denoted as scheduling resource #2) it can be with respective antenna port set #1 and antenna port group #2, antenna port group # 1 includes port #7, and antenna port group #2 includes port #9, then scheduling resource #1 corresponding ports #7, scheduling resource #2 corresponding ports # 9.Optionally, at least one antenna port included by every group of antenna port meets QCL.
It is corresponded with the M network equipment alternatively, it is also possible to be interpreted as multigroup scheduling resource.That is, each group Scheduling resource can dispatch a network equipment, and the M network equipment can be dispatched in target dispatch resource.For example, when M=2, Target dispatch resource includes scheduling resource #1 and is denoted as scheduling resource #2, and scheduling resource #1 can be used for dispatching first network and set Standby, scheduling resource #2 can be used for dispatching another network equipment in addition to first network equipment and (be set for example, being denoted as the second network It is standby).It is understood that the target dispatch scheduling of resource network equipment, such as scheduling resource #1 scheduling first network equipment refers to, When needing to send downlink data, first network equipment can send the downlink data on scheduling resource #1, in other words under this Row data can be carried on scheduling resource #1.
Optionally, as the application one embodiment, the same word in the domains same resource distribution RA in the DCI can be used Section, in other words in the same domains RA in the DCI same field bit information, indicate the target dispatch resource.The same word Section can be a bitmap (bitmap) in a domain RA.One domain RA refers to based on the resource distribution in DCI in LTE protocol (resource block assignment) field.Content in the domains RA is a bitmap.Determining DCI format (format) And after resource distribution mode used by the domains RA, can be determined according to downlink system bandwidth bit number that the domains RA occupy or Referred to as bit.
In this way, indicating that multigroup scheduling resource can save signaling overheads by a bitmap in a domain RA.
The DCI format of the embodiment of the present application, such as can be DCI format (format) 2D, it can also be DCI format 2A. The application is not especially limited DCI format.
Using DCI format as DCI format 2D for example, the two spike-type cultivars method of salary distribution is supported in the domains RA of format 2D DCI：Class Type 0 (type 0) and Class1 (type 1).Wherein, type 0 is the instruction that resource is scheduled as unit of RBG.Type 1 It can be grouped by resource, offset (shift) indicates, RB indicates to indicate the scheduling resource of RB granularities.
First, the concept of RBG is introduced.
RBG is one group of continuous localized resource blocks (localized VRB, VRB).Size (P, i.e., each RBG of RBG In include VRB numbers.The VRB numbers that the last one RBG includes are likely less than P) it is related to (downlink) system bandwidth, correspondence is such as Shown in table 1：
1 RBG sizes (size) of table and downlink system bandwidthRelationship (36.213 Table 7.1.6.1-1)
Corresponding downlink system bandwidthThe total N of RBGRBGFor：
Wherein, precedingThe size of a RBG is P,Expression rounds up.
It is 25RB with downlink system bandwidth in the case where the resource distribution mode that the domains RA of the DCI use is type 0 For, by searching for table 1 it is recognised that the sum of the size P=2, RBG of RBGThen should The bitmap (bitmap) in the domains RA includes 13 bits altogether.Wherein, preceding as shown in (a) in Fig. 3 for 13 RBG that can be dispatched Each RBG sizes of 12 RBG are 2, the size of the last one RBG is 1.If bitmap includes 13 bits altogether.If the RA The bitmap in domain is：1001110100010, then target dispatch resource is RBG0, RBG 3, RBG 4, RBG 5, RBG 7, RBG 11 (shown in (b) in such as Fig. 3), the resource for distributing to terminal in other words are RBG 0, RBG 3, RBG 4, RBG 5, RBG 7, RBG 11。
For in other DCI formats, the occupied bit number in the domains RA is referred to existing protocol, for sake of simplicity, herein It repeats no more.
Optionally, it as the application one embodiment, can be indicated by extending the domains RA in the DCI in existing protocol M group scheduling resources.
For example, may include two domains RA as M=2, in DCI, the format of the DCI behind the domains extension RA can be example Such as form as shown in Figure 4.Wherein, a domain RA is used to indicate a group scheduling resource.As shown in (a) in Fig. 4, it can will claim The DCI includes 2 domains RA (for example, being denoted as the domains RA #1 and RA domain #2), as shown in (b) in Fig. 4, can also claim the RA after extension Domain is a domain RA, but the domains RA include 2 bitmaps (bitmap) (for example, being denoted as bitmap #1 and bitmap #2).
In addition, multigroup scheduling resource, can be it is orthogonal in time domain and/or frequency domain, can also be in time domain and frequency domain It is completely overlapped, it can also partly overlap in time domain and/or frequency domain.
For example, as shown in figure 5, scheduling resource #1 and scheduling resource #2 are orthogonal, i.e., it is not overlapped completely；Such as (a) institute in Fig. 6 Show, scheduling resource #1 and scheduling resource #2 partly overlap；As shown in (b) in Fig. 6, scheduling resource #1 and scheduling resource #2 are complete Overlapping.
For another example, it is further assumed that target resource shown in Fig. 5 and Fig. 6 is 6RBG, and adjacent RBG shown in the drawings The index of represented RBG is also adjacent, and the RBG represented by RBG adjacent in other words is practical to be continuous, it can be seen that As shown in figure 5, scheduling resource #1 and scheduling resource #2 are orthogonal on frequency domain；As shown in (a) in Fig. 6, scheduling resource #1 and tune Degree resource #2 partly overlaps in time domain and frequency domain；As shown in (b) in Fig. 6, scheduling resource #1 and scheduling resource #2 are in time domain With it is completely overlapped on frequency domain.
For another example, it is assumed that the RBG represented by adjacent RBG shown in the drawings is not necessarily continuous, such as from top to bottom, in figure Shown 6RBG respectively represents RBG 0, RBG 3, RBG 4, RBG 5, RBG 7, RBG 11 shown in (b) in Fig. 3, then such as Shown in Fig. 5, for (b) in Fig. 5, scheduling resource #1 includes RBG 0, RBG 3, RBG7 and RBG 11, scheduling resource #2 packets RBG 4, RBG 5 are included, scheduling resource #1 and scheduling resource #2 are not overlapped completely；As shown in (a) in Fig. 6, scheduling resource #1 packets RBG 0, RBG 3, RBG 4 and RBG 5 are included, scheduling resource #2 includes RBG 4, RBG 5, RBG 7 and RBG 11, scheduling resource #1 It is overlapped on RBG 4 and RBG 5 with scheduling resource #2, that is to say, that first network equipment and second network equipment can be simultaneously Downlink data is transmitted on RBG 4 and RBG 5.As shown in (b) in Fig. 6, scheduling resource #1 and scheduling resource #2 in time domain and It is completely overlapped on frequency domain, include RBG 0, RBG 3, RBG 4, RBG 5, RBG 7 and RBG 11, that is to say, that first network Equipment and second network equipment can transmit downlink number on RBG 0, RBG 3, RBG 4, RBG 5, RBG 7 and RBG 11 simultaneously According to.
S220, first network equipment send the DCI.Correspondingly, terminal receives the DCI.
According to the first DCI, more specifically according to the bit information in the domains RA in the DCI, terminal can determine the target Resource.For example, in the case where terminal determines that the DCI is DCI format 2D and the domains RA resource distribution mode is Class1, work as RA The bit information in domain be 1001110100010 when, then terminal can determine target dispatch resource be RBG 0, RBG 3, RBG 4, RBG 5、RBG 7、RBG 11。
Optionally, returning method can also include：
S230, terminal determine the relationship of multigroup scheduling resource.
That is, terminal determines that multigroup scheduling resource belongs to any in following relationship or is not belonging to any：When It is orthogonal on domain and/or frequency domain, it is completely overlapped in time domain and frequency domain, it partly overlaps in time domain and/or frequency domain.It can will be multigroup Above-mentioned three kinds of relationships of scheduling resource are known as overlapping relation.
In the following, being described in detail in conjunction with a variety of situations.
Situation one：Network side (for example, network equipment) or agreement do not make the overlapping relation of multigroup scheduling resource any It limits.
In this case, multigroup scheduling resource may be orthogonal in time domain and/or frequency domain, can also can be in time domain and frequency domain It is upper completely overlapped, it is also possible to partly overlap in time domain and/or frequency domain.In one possible implementation, terminal needs true The overlapping relation of fixed multigroup scheduling resource is specially any in above-mentioned three kinds of situations.Alternatively, terminal at least it needs to be determined that The relationship of multigroup scheduling resource is orthogonal or overlapping (including be all overlapped and partly overlap).
Situation two：Network side (for example, network equipment) or agreement regulation, the relationship of multigroup scheduling resource be only possible to be In time domain and/or frequency domain it is orthogonal and in time domain and frequency domain both completely overlapped situations.
Situation three：Network side (for example, network equipment) or agreement regulation, the relationship of multigroup scheduling resource be only possible to be Partly overlap in time domain and/or frequency domain or it is non-it is partly overlapping (including it is completely overlapped in time domain and frequency domain, time domain and/ Or both orthogonal possibility on frequency domain) both situations.
Which kind of either above-mentioned situation, optionally, the network equipment can be by indicating information (hereinafter, for the ease of understanding And description, it is denoted as the first instruction information) display or implicitly indicate the relationship of multigroup scheduling resource.For situation one, terminal root According to the first instruction information, it may be determined that the relationship of multigroup scheduling resource is specially any in above-mentioned three kinds of situations.Alternatively, Terminal can at least determine that the relationship of multigroup scheduling resource is orthogonal or overlapping according to the first instruction information.Alternatively, terminal According to the first instruction information, it can at least determine that the relationship of multigroup scheduling resource is orthogonal or partly overlaps or weigh completely It is folded.For example, the first instruction information can occupy a bit, 0 indicates that the relationship of multigroup scheduling resource is orthogonal, and 1 indicates The relationship of multigroup scheduling resource is non-orthogonal, that is, is partly overlapped or completely overlapped situation.For situation two, terminal according to First instruction information, it may be determined that the relationship of multigroup scheduling resource is specifically orthogonal or completely overlapped.For situation Three, terminal is according to the first instruction information, it may be determined that the relationship of multigroup scheduling resource is specifically that positive part overlapping is also non-portion Divide overlapping.
The application couple first indicates that the specific format of information or form are not construed as limiting, for example, the first instruction information can be High-level signaling can also be and be carried on the DCI.
Further, the first instruction information can be QCL information, which can be carried on physical layer signaling (such as On DCI.More specifically, the QCL information is carried on the domains PQI of the DCI.That is, the bit information in the domains PQI is used for Indicate the QCL information.Alternatively, the QCL information is carried in a certain domain of signaling, the domain it could also be possible that the high-level signaling or The domain extended in person's MAC layer signaling or physical layer signaling (such as definition " resource grouping instruction information field ")
For example, when the QCL information be single QCL information or be a pilot tone/port/running time-frequency resource information constantly, eventually End can determine that multigroup scheduling resource is orthogonal in time domain and/or frequency domain；When the QCL information is more QCL information or is Constantly, terminal can determine the complete in time domain and frequency domain of multigroup scheduling resource to multiple pilot tone/port/running time-frequency resource information Overlapping.For another example when the QCL information is the QCL information of reserved (reserved), terminal can determine multigroup scheduling money Source is orthogonal in time domain and/or frequency domain, wherein reserved QCL information can be presented as some bit instructions (e.g., 00) of PQI
It should be understood that network side (for example, network equipment) or agreement etc. can also pre-define the pass of multigroup scheduling resource System can only be orthogonal in time domain and/or frequency domain, or can only be completely overlapped in time domain and frequency domain, or can only be in time domain And/or partly overlap on frequency domain, terminal need not execute S230 at this time.
S240, terminal are determined according to the DCI per group scheduling resource.
In the following, the step is described in detail according to the classification of the overlapping relation of multigroup scheduling resource.
(1) completely orthogonal
For example, terminal determines that multigroup scheduling resource is orthogonal in time domain and/or frequency domain according to the first instruction information, or Person provides that multigroup scheduling resource is orthogonal in time domain and/or frequency domain in network side/agreement etc..
Optionally, terminal can be determined in conjunction with resource pattern and the DCI per group scheduling resource.Wherein, resource pattern is used for Indicate the relative position relation of the M group schedulings resource.
Non-limiting as example, which can be with RBG or RB staggered pattern, such as with one Pattern (for example, as shown in (a) in Fig. 5) staggered a RBG or RB, such as with figure staggered two RBG or RB Sample (for example, as shown in (b) in Fig. 5), such as with pattern staggered three RBG or RB (for example, such as (c) institute in Fig. 5 Show).Target dispatch resource indicated in resource pattern and DCI is preset according to this, terminal can determine every group scheduling resource, than Such as determine scheduling resource #1 and scheduling resource #2.
Further, the arrangement pattern of continuous RBG or RB, but the embodiment of the present application pair can be indicated by presetting resource pattern This is not construed as limiting.For example, the default resource pattern of the embodiment of the present application can indicate the arrangement pattern of discrete RBG or RB. It, can according to presetting resource pattern and some or all of can not determine in target dispatch resource the grouping belonging to resource To combine other means, such as the parity bit of the bit in the domains RA etc. to determine grouping belonging to resource.
Optionally, terminal is determined according to resource occupation ratio and/or the DCI per group scheduling resource.
Non-limiting as example, which refers to the ratio that every group scheduling resource accounts for target dispatch resource, Such as the resource occupation ratio can refer to that each group scheduling resource (for example, scheduling resource #1 and scheduling resource #2) accounts for target dispatch The half of resource.Wherein, smaller RBG or RB are indexed and belongs to scheduling resource #1, indexed larger RBG or RB and belong to scheduling money Source #2；Alternatively, indexing smaller RBG or RB belongs to scheduling resource #2, indexes larger RBG or RB and belong to scheduling resource #1.It answers Understanding, the ratio that the application occupies each group scheduling resource target dispatch resource is not construed as limiting, in specific embodiment, Ke Yigen According to the network equipment, for example, the ratio is arranged in the historic demand of first network equipment and second network equipment.
Optionally, terminal can be determined according to the characteristic information of the bit in the domains RA per group scheduling resource.
Specifically, the characteristic information can be location information, and the characteristic information can also be according to the ratio in the domains RA What special numerical value determined.Also, the resource indicated by the bit with same characteristic features information belongs to same group scheduling resource.Ying Li Solution, the characteristic information of bit can be understood as the characteristic information of resource.Resource with same characteristic features information belongs to same group of tune Spend resource.Location information is it can be appreciated that index information, the i.e. index of resource.The numerical information of the bit in the domains RA can indicate Whether resource can be used.
For example, location information can be specifically the position of bit in the domains RA or the index of bit is to belong to odd term Or even item.In other words, can will be position in the domains RA it be that the bit of odd term is divided into one group (for example, being denoted as a group # 1), the bit that position is even item is divided into one group (for example, being denoted as a group #2).Then, then respectively determine institute in group #1 and group #2 Including target dispatch resource.It should be understood that for the bit in group #1, if the bit value is 0, then it represents that indicated by the bit RBG or RB be not belonging to target dispatch resource, if the bit value be 1, then it represents that RBG or RB indicated by the bit belong to mesh Mark scheduling resource.Similarly for group #2.In this way, can determine a group scheduling resource according to the bit value in group #1, such as dispatch Resource #1 can determine a group scheduling resource, such as scheduling resource #2 according to the bit value in group #2.Come in conjunction with (a) in Fig. 7 It says, it is assumed that the bitmap in the domains RA is 111011, and when scheduling of resource particle is RBG, the target dispatch resource scheduled in DCI includes RBG 0, RBG 1, RBG 2, RBG 4 and RBG 5.By the group #1 of odd term in bitmap 111011：111, in bitmap 111011 The group #2 of even item：101, respectively represent different resource groups.Wherein, #1 is organized：Scheduling resource #1 representated by 111 includes RBG 0, RBG2 and RBG 4 organize #2：Scheduling resource #2 representated by 101 includes RBG 1 and RBG 5.
For example, location information may also mean that in all bits corresponding to target dispatch resource, each bit Position belongs to odd term or even item.Specifically, can be by all bits corresponding to target dispatch resource, odd number The bit of item is divided into one group (for example, being denoted as a group #3), and the bit that position is even item is divided into one group (for example, being denoted as a group #4). A group scheduling resource, such as scheduling resource #1 can be determined according to group #3, and another group scheduling resource can be determined according to #4, such as Scheduling resource #2.For (b) in Fig. 7, it is similarly assumed that the bitmap in the domains RA is 111011, then in scheduling of resource particle For RBG when, the target dispatch resource scheduled in DCI includes RBG 0, RBG 1, RBG 2, RBG4 and RBG 5.In RBG 0, RBG 1, in RBG 2, RBG 4 and RBG 5, the group of odd term, that is, the resource organized represented by #3 includes RBG 0, RBG 2 and RBG 5, very Several groups, that is, the resource organized represented by #4 includes RBG 1 and RBG 4.So as to learn, scheduling resource #1 include RBG 0, RBG 2 and RBG 5, scheduling resource #2 include RBG 1 and RBG 4.
In the characteristic information determined according to the numerical value of the bit in the domains RA, for example, can be according to bitmap bit Value, the RB/RBG indicated by the identical bit of remainder that bit value divided by N are obtained is as one group of resource.N may be greater than or Integer equal to 2, for example, N can be the number for the network equipment for carrying out CoMP cooperation transmissions.N can be predefined or by net Network equipment passes through signal deployment/issue.The signaling can be high-level signaling, which can also be carried on DCI, for example, by The network equipment informs the value of terminal N by DCI.For example, when bitmap is 110011,6 bits, bit value divided by 2 (2 are shared A collaborative network equipment), the resource indicated by the identical bit of remainder values is a scheduling resource group.For example, when N=2,0, 1,2,3,4,5 this 6 bit positions divided by 2 remainder are respectively 0,1,0,1,0,1, then bit position institute generation of the remainder for 0 The resource of table is a group scheduling resource, for example, scheduling resource #1；The resource representated by bit position that remainder is 1 is one group of tune Resource is spent, for example, scheduling resource #2.It is 110011 in bitmap in conjunction with shown in (c) in Fig. 7, the target dispatch resource packet of expression In the case of including RBG 0, RBG 1, RBG 4 and RBG 5, scheduling resource #1 includes RBG 0 and RBG 4, and scheduling resource #1 includes RBG 1 and RBG 5.
In the characteristic information determined according to the numerical value of the bit in the domains RA, for example, can also will be according to bitmap Bit value, the RB/RBG indicated by the identical bit of quotient that bit value divided by Q are obtained is as one group of resource.Q may be greater than Or the integer equal to 2, for example, Q can be the number for the network equipment for carrying out CoMP cooperation transmissions, Q may be all available The half of resource.Q can be predefined or be passed through signal deployment/issue by the network equipment.The signaling can be high-level signaling, should Signaling can also be carried on DCI, inform the value of terminal Q by DCI by the network equipment.For example, all available resources are 6RBG When, Q=3 is enabled, when bitmap is 110011,1,2,3,4,5 this 6 bit positions divided by 2 quotient are respectively 0,0,0,1,1,1, The resource representated by bit position that so quotient is 0 is a group scheduling resource, for example, scheduling resource #1；The bit position that quotient is 1 Representative resource is a group scheduling resource, for example, scheduling resource #2.It is 110011 in bitmap in conjunction with shown in (d) in Fig. 7, In the case that the target dispatch resource of expression includes RBG 0, RBG 1, RBG 4 and RBG 5, scheduling resource #1 includes 0 Hes of RBG RBG 1, scheduling resource #2 include RBG 4 and RBG5.
Optionally, terminal by according to the initial position of the DCI and/or the M group schedulings resource and/end position, Determine the M group schedulings resource.For example, terminal can determine M group scheduling resources by the separation between each group scheduling resource Initial position and/end position, and then determine per group scheduling resource.
For example, the network equipment can indicate the separation between each group scheduling resource to terminal.For example, passing through bitmap Form indicates the separation between each group scheduling resource.Be used to indicate the separation between each group scheduling resource bitmap (for example, Be denoted as separation instruction information) bit number can be consistent with the bit number in the domains RA, such as the domains RA occupy 6 bit when, separation Indicate that information occupies 6 bits.1 number can be M-1 in separation instruction information, for example, when M=2, separation indicates information In 1 number be 1, be one group of resource, such as scheduling resource #1 in the RB/RBG before 1, which is another Group resource, such as scheduling resource #2.In the embodiment of the present application, separation instruction information can be configured by RRC/MAC CE/DCI Or it issues.For example, being 110011 in bitmap, the target dispatch resource of expression includes the feelings of RBG 0, RBG 1, RBG 4 and RBG 5 Under condition, if separation instruction information be 000100, terminal it was determined that scheduling resource #1 includes RBG 0 and RBG 1, scheduling resource #2 include RBG 4 and RBG 5.
It should be noted that the characteristic information of above-mentioned resource pattern, resource occupation ratio, terminal according to the bit in the domains RA Used rule etc. can be default or predefined when determining per group scheduling resource, can also be that the network equipment passes through height What layer signaling or DCI were configured/are issued.For ease of description and understand, in above-mentioned resource pattern, resource occupation ratio, terminal Used rule etc. is default or predefined feelings when being determined per group scheduling resource according to the characteristic information of the bit in the domains RA Under condition, resource pattern, resource occupation ratio, terminal can be determined according to the characteristic information of the bit in the domains RA per group scheduling resource When used rule be referred to as preset rules.Can also be that terminal can be according to preset rules and/or the finger of the network equipment Show, determines per group scheduling resource.
Can also be the network equipment and terminal (such as it should also be understood that the preset rules for example can be as defined in agreement One network equipment, second network equipment and terminal) appointed in a manner of static or is dynamic in advance.The mode of so-called static state It can be understood as the network equipment and terminal and no longer change the rule within very long a period of time after appointing the preset rules Then.So-called dynamic mode can be understood as the network equipment and terminal within a period of time after appointing the preset rules again The preset rules are updated.
(2) completely overlapped
For example, terminal determines that multigroup scheduling resource is completely overlapped in time domain and frequency domain according to the first instruction information, Or multigroup scheduling resource is provided when completely overlapped in time domain and frequency domain in network side/agreement etc., terminal can direct root Each group scheduling resource is determined according to target resource determined by DCI, i.e., is all the target dispatch resource per group scheduling resource.For example, If the bitmap in the domains RA is in DCI：1001110100010, then each group scheduling resource, for example, scheduling resource #1 and scheduling resource #2 Include RBG 0, RBG 3, RBG 4, RBG 5, RBG 7, RBG 11.
Optionally, completely overlapped in time domain and frequency domain in multigroup scheduling resource, this method can also include：
The terminal determines the antenna end corresponding to the data carried in target dispatch resource according to the second instruction information The quantity of mouth group.Wherein, it is integer that the quantity of the antenna port group, which is N, 1≤N≤M, and N,.
Optionally, the second instruction information is that high-level signaling or the second instruction information are carried on the DCI.
Further, the second instruction information can be QCL information, which is carried on the DCI.More Body, which is carried on the domains PQI of the DCI.That is, the bit information in the domains PQI is used to indicate the QCL Information.
For example, when the QCL information is list QCL information, terminal can determine the number carried in target dispatch resource Quantity according to corresponding antenna port group is 1；When the QCL information is more QCL information, terminal can be determined in target tune The quantity for the antenna port group corresponding to data that degree resource is carried is M.For another example when the QCL information illustrates that K are led When frequently/port/running time-frequency resource information, terminal can determine the antenna port corresponding to the data carried in target dispatch resource The quantity of group is K, wherein 1<=K<=M.
Further, in the case where the quantity of the network equipment of the target dispatch resource transmission data is M, this method Can also include：Terminal passes through the data that are carried on target resource described in certain demodulating algorithm, wherein the demodulating algorithm can To include that (Interference cancellation, IC) or serial interference elimination (serial IC, SIC) are eliminated in interference, Or (Network assistant are eliminated in the interference of parallel interference canceller (Parallel IC, PIC) or network side auxiliary IC, NAIC).
(3) it partly overlaps
For example, terminal determines that multigroup scheduling resource partly overlaps in time domain and/or frequency domain according to the first instruction information Or provide that multigroup scheduling resource partly overlaps in time domain and frequency domain in network side/agreement etc..
Optionally, the network equipment can be by indicating that information (for example, being denoted as third indicates information) informs the terminal part The resource (hereinafter, for ease of description, which being denoted as overlapped resource) of overlapping.If the network equipment receives Information is indicated to third, then can determine the overlapped resource in multigroup scheduling resource, and can indicate information in conjunction with third With target dispatch resource, each group scheduling resource is determined.
For example, third instruction information can be message bit pattern, and the network equipment indicates overlapping money by way of bitmap The range in source.Third indicates that the bit number that information occupies can be identical as the bit number that the domains RA occupy.For example, third indicates information Can only occur two 1, indicate that the two resources between 1 are overlapped resource.For example, the bitmap in the domains RA is in DCI： 1001110100010, including 13 bits, target dispatch resource are RBG 0, RBG 3, RBG 4, RBG 5, RBG 7 and RBG 11.Third indicates that information can also include 13 bits, it is assumed that third indicates that information is 0000100001000, then each group tune Resource is spent, if the overlapped resource of scheduling resource #1 and scheduling resource #2 are RBG 5 and RBG 7.If the prespecified overlapping money of system The resource indicated by the bit before bit in the corresponding domains RA in source bit position belongs to scheduling resource #1, bit institute later The resource of instruction belongs to scheduling resource #2, then can be determined with terminal scheduling resource #1 include RBG 0, RBG 3, RBG 4, RBG 5, RBG 7, scheduling resource #1 include RBG 5, RBG7 and RBG 11.
Further, this method can also include：
Terminal determines the M group schedulings resource point according to the correspondence of M groups antenna port and the M group schedulings resource Not corresponding antenna port group.
Optionally, M groups antenna port and the correspondence of the M group schedulings resource be can be pre-set, can also It is that terminal is determined according to the 4th instruction information.4th instruction information can be high-level signaling, can also be carried on the DCI.
