In the prior art, referring to FIG. 3, DCI and the DCI that terminal device is sent according to the network equipment are occupied PDCCH resource, the step of determining the PUCCH resource for sending UCI, are as follows.Present invention primarily contemplates terminal device reception is multiple DCI, and feed back in same uplink PUCCH resource the situation of the reception condition of the downlink data of multiple DCI instruction.
S301: the network equipment is to the multiple PUCCH resource set of terminal equipment configuration.
The network equipment gives terminal equipment configuration multiple PUCCH resources by high-level signaling, such as RRC signaling, usually 4-8 It is a, for example, PUCCH resource 1 indicates to occupy Physical Resource Block 1 (Physical Resource Block, PRB) and symbol 1 is simultaneously UCI is transmitted using PUCCH format0, PUCCH resource 2 indicates to occupy PRB2 and symbol 2, symbol 3, symbol 4 and symbol 5, And use PUCCH format1 transmission UCI etc..According to PUCCH resource instruction (PUCCH resource indicator) in DCI Multiple PUCCH resource is divided into 4 PUCCH resource set by the bit number (2 bit) that field includes, with the network equipment to terminal For 8 PUCCH resources of device configuration, then in each PUCCH resource set comprising there are two PUCCH resources, such as Fig. 4 institute Show.
S302: the network equipment determines terminal device for sending the PUCCH resource of UCI.
The network equipment determines a PUCCH resource from multiple PUCCH resources, and the PUCCH of UCI is sent for terminal device Resource.For example, the network equipment determines that first PUCCH resource in PUCCH resource set 01 is that terminal device sends UCI's PUCCH resource.
S303: the network equipment sends multiple DCI to terminal device in multiple PDCCH resources.
The network equipment sends DCI to terminal device in multiple PDCCH resources, with the PDSCH resource that is indicated by DCI to Terminal device sends downlink data, and is referred to by DCI and the occupied PDCCH resource of the last one DCI to terminal device Show this for sending the PUCCH resource of UCI.Each PDCCH resource in multiple PDCCH resource is by control channel element CCE composition.As shown in fig. 5, it is assumed that the bandwidth of the control channel of entire wireless communication system can be divided into 16 CCE, respectively For CCE0-CCE15, it is assumed that the network equipment dispatches 3 PDCCH resources, then first PDCCH resource can be by CCE0 and CCE1 group At second PDCCH resource can be made of CCE2, and third PDCCH resource can be made of CCE3 and CCE4, the network equipment 3 DCI are sent in 3 PDCCH resources.The letter of each DCI in 3 DCI in addition to the PDSCH resource comprising instruction Breath, also includes uplink control channel resource instruction information (PUCCH resource indicator), which includes 2 Which in 4 PUCCH resource set using network equipments configuration a bit, the instruction information are used to indicate to terminal device A PUCCH resource set, the value of the instruction information correspond to the serial number of PUCCH resource set, for example, the instruction information is 01, then Instruction uses PUCCH resource set 01.Terminal device is determined according to the occupied PDCCH resource of the last one DCI for sending The formula of the PUCCH resource of UCI is as follows:
Wherein, r is for sending serial number of the PUCCH resource of UCI in PUCCH resource set 01, due to each PUCCH It include 1 or 2 PUCCH resources in resource collection, for example, the network equipment gives terminal equipment configuration 8 PUCCH resources, Then there are 2 PUCCH resources in each PUCCH resource set；The network equipment is less than 8 PUCCH resources to terminal equipment configuration, It then then only include 1 PUCCH resource in some PUCCH resource set, therefore, the value of the serial number is 0 or 1；M is PUCCH The PUCCH resource number for including in resource collection is 1 or 2, and L is the aggregation level of the occupied PDCCH of the last one DCI, Can be 1,2,4,8,16, C be the occupied PDCCH resource of the last one DCI starting CCE serial number.If network equipment scheduling 3 A PDCCH resource, then the occupied PDCCH resource of the last one DCI is third PDCCH resource, in order to enable terminal device Enough determine that then the network equipment will control third PDCCH money using first PUCCH resource in PUCCH resource set 01 The ratio of the aggregation level of the starting CCE and the PDCCH in source and the value after M progress modulo operation are 0, therefore, if the network equipment Control third PDCCH resource aggregation level be 2, then third PDCCH resource originate CCE serial number can be 0,4,8, Any one in 12, then when dispatching third PDCCH resource, then the third PDCCH resource is necessary for the network equipment One in CCE0-CCE1, CCE4-CCE5, CCE8-CCE9 and CCE12-CCE13, the network equipment can be according to the actual situation One of them is selected, for example, determining that third PDCCH resource is CCE0-CCE1.And to first PDCCH resource and second The starting CCE serial number and aggregation level of PDCCH resource there is no limit, the network equipments can be with arbitrary disposition, then the network equipment is then 3 DCI are sent in this 3 PDCCH resources.
S304: terminal device receives multiple DCI in multiple PDCCH resources.
Terminal device is after receiving the DCI information, according to the PDCCH of the DCI received and the last one DCI occupancy The aggregation level of the starting CCE serial number of resource and the PDCCH resource determines the PUCCH resource for sending UCI.It is specific true Determine shown in mode such as formula (1), details are not described herein.
However, the last one DCI for causing terminal device to receive is simultaneously due to there is the case where losing in transmission process It is not the last one DCI that the network equipment is sent, then, the occupied PDCCH money of the last one DCI that terminal device receives Source is also not the last one PDCCH resource of network equipment scheduling, then the PUCCH for being used to send UCI that terminal device is determined Resource is not just the practical terminal device that is indicated to of the network equipment for sending the PUCCH resource of UCI, to cause PUCCH resource Determination mistake, the ascending resource for sending UCI with other terminal devices clashes, and causes the network equipment that may not receive The ACK/NACK response of terminal device feedback or the ACK/NACK response for receiving mistake.

S601: base station sends downlink information to the terminal device on N number of downlink resource.
In the embodiment of the present application, downlink resource can be PDCCH resource and/or PDSCH resource, correspondingly, downlink letter Breath can be DCI and/or downlink data, i.e. base station can send DCI to UE in PDCCH resource, can also be in PDSCH resource On to UE send downlink data, be also possible to base station and first pass through PDCCH resource to send DCI to UE, and by PDSCH resource to UE It sends downlink data or base station and dispatches PDCCH resource simultaneously on different frequency domain positions to UE transmission DCI and scheduling PDSCH resource sends downlink data to UE.Certainly, downlink resource is also possible to MPDCCH resource etc., in the embodiment of the present application It is illustrated so that downlink resource is PDCCH resource and PDSCH resource as an example.
Base station is communicated by scheduling PDCCH resource and PDSCH resource with UE.For example, time division duplex can be used (time division duplexing, TDD) mode or carrier wave polymerization (carrier aggregation, CA) mode and UE into Row communication.Both working methods will be illustrated so that PDCCH resource and UE communication are dispatched in base station as an example below:
1) TDD mode:
Base station can dispatch multiple PDCCH positioned at similar and different frequency domain position on different time-domain positions and provide Source sends DCI information to UE.As shown in figure 5, base station scheduled 3 PDCCH resources, wherein the corresponding time slot of PDCCH resource 1 (slot) 1 and frequency 1, the corresponding slot2 of PDCCH resource 2 and frequency 2, the corresponding slot3 of PDCCH resource 3 and frequency 3.
2) CA mode:
Base station can dispatch multiple PDCCH resources on different carrier waves on the same time-domain position, send to UE DCI information.As shown in fig. 7, base station scheduled 3 PDCCH resources, wherein PDCCH resource 1 is located on carrier wave 1, and occupy The PDCCH resource of carrier wave 1 is CCE0-CCE1, and PDCCH resource 2 is located on carrier wave 2, and the PDCCH resource of the carrier wave 2 occupied is CCE4-CCE6, the PDCCH resource for the carrier wave 3 that PDCCH resource 3 is corresponded on carrier wave 3, and occupied are CCE9.It should be noted that The number of CCE on each carrier wave can be independent from each other, i.e., carrier wave 1 is corresponding by 9 CCE, the CCE serial number of PDCCH resource 1 For the serial number in 9 CCE of carrier wave 1, serial number of the CCE serial number of PDCCH resource 2 in multiple CCE of carrier wave 2.
When base station sends multiple DCI to UE in multiple PDCCH resources, and sent in the PDSCH resource of DCI instruction to UE The position of downlink data, the PDSCH resource is similar with Fig. 5, Fig. 7, and details are not described herein.
In the embodiment of the present application, base station also needs to determine multiple PDCCH according to being indicated to resource of the UE for sending UCI Resource, and/or multiple PDSCH resources are determined for sending the resource of UCI according to UE is indicated to.For example, in multiple PDCCH resources In, there are at least two first PDCCH resources, which is used to show instruction for sending to UE is hidden The ascending resource of UCI, by the frequency domain resource of each of at least two the oneth PDCCH PDCCH, determining UE is for sending out Send the PUCCH resource of UCI identical, then base station need according to the UE of instruction send UCI resource determine this at least two first PDCCH resource, the PDCCH resource in addition at least two first PDCCH resource, base station can be directly according to the reality of downlink resource Border service condition determines.
It should be noted that any one determination at least two first PDCCH resource can be used in base station or UE UE sends the ascending resource of UCI, can also determine that UE sends the uplink of UCI together according at least two first PDCCH resource Resource, in this application with no restriction.In addition, the title of at least two first PDCCH resources be intended merely to it is convenient with it is N number of Other PDCCH for being not used in the determining PUCCH resource in PDCCH are distinguished, and one used calls, this at least two Other title also can be used in first PDCCH resource, and this is not restricted.
In one possible implementation, when downlink resource is PDCCH resource, at least two the oneth PDCCH money Source includes: the last one PDCCH money in first PDCCH resource and N number of PDCCH resource in N number of PDCCH resource Source；Or second PDCCH resource in first PDCCH resource and N number of PDCCH resource in N number of PDCCH resource；Or Most latter two PDCCH resource in N number of PDCCH resource；Or any three PDCCH resources in N number of PDCCH resource；Or Any i PDCCH resource in N number of PDCCH resource, i are the integer more than or equal to 2 and less than or equal to N.When downlink resource is When PDSCH resource, at least two the oneth PDSCH resource is similar at least two first PDCCH resource, no longer superfluous herein It states.
It should be noted that at least two first PDCCH resource or at least two the oneth PDSCH resource can be base It stands as defined in the perhaps standard appointed in advance with UE or static/is semi-statically configured, be also possible to base station determine should After at least two first PDCCH resources or at least two the oneth PDSCH resource, by indicating that information is indicated to UE, at this Apply in embodiment with no restriction.
In a kind of possible embodiment, ascending resource can be PUCCH resource.It certainly, if can also be by other Row resource bearing UCI, then ascending resource is also possible to other resources, and this is not restricted.For convenience of description, uplink is provided below Source is illustrated by taking PUCCH resource as an example.It is what UE was configured that the PUCCH resource, which can be base station in advance, such as the S301 institute in Fig. 3 It states, details are not described herein.
In the embodiment of the present application, when downlink resource is PDCCH resource, which includes: the frequency domain of PDCCH One of resource, time-domain resource, code domain resource and port numbers are a variety of, i.e., base station can by the frequency domain resource of PDCCH, One of time-domain resource, code domain resource and port numbers are a variety of, show the PUCCH resource indicated for sending UCI to UE is hidden Serial number.It specifically can be hidden according to the initial position of the frequency domain resource of PDCCH and/or time-domain resource, end position or number Show the serial number indicated for sending the PUCCH resource of UCI.Base station is hidden to show serial number of the instruction for sending the PUCCH resource of UCI Mode can be as shown in the formula (1) in the S303 in Fig. 3, wherein uses when base station is determined by any one resource of PDCCH When sending the serial number of PUCCH resource of UCI, the definition of the M in formula (1) is constant, and the DCI to send in PDCCH resource refers to The number for the PUCCH resource for including in the PUCCH resource set shown, and the PDCCH that the definition of formula C and L are used according to base station The difference of resource and change, parameter L can also not be used in formula (1).For example, when base station can be provided by the frequency domain of PDCCH Source is hidden when showing the serial number for indicating the PUCCH resource for sending UCI, and C is the starting CCE serial number of the frequency domain resource of PDCCH, or Terminate CCE serial number or CCE number etc., parameter L can not used in the aggregation level or formula (1) that L is PDCCH；When When base station can show the serial number for indicating the PUCCH resource for sending UCI by the way that the time-domain resource of PDCCH is hidden, C is PDCCH's The primary sign or terminating symbol of time-domain resource or symbol numbers etc. can not use parameter L at this time in formula (1)；Work as base It stands when can show the serial number for indicating the PUCCH resource for sending UCI by the way that the code domain resource of PDCCH is hidden, C is the code of PDCCH The sequence identifier of domain resource can not use parameter L at this time in formula (1)；Show instruction when the port numbers that base station passes through PDCCH are hidden When the serial number of the PUCCH resource for sending UCI, calculation formula can become: r=Mod (Q, M), wherein Q is the end of PDCCH Slogan.When base station using PDCCH multiple resources it is hidden show the serial number for indicating PUCCH resource for sending UCI when, for example, base The frequency domain resource stood using PDCCH with port numbers are hidden shows the serial number indicated for sending the PUCCH resource of UCI, then calculation formula It can be with are as follows: r=Mod ((C/L)+Q, M), it is of course also possible to use other calculation formula, this is not restricted.
When downlink resource is PDSCH resource, which includes: the frequency domain resource, time-domain resource, code domain of PDSCH One of resource and port numbers are a variety of.The specific hidden method for showing instruction is identical as PDCCH resource, and details are not described herein.
It should be noted that the hidden serial number and each resource for showing instruction PUCCH resource of which kind of resource that base station uses Determine that the calculation formula of the serial number of PUCCH resource can be as defined in base station is set in advance in advance with UE or standard, Huo Zhejing State/be semi-statically configured, it is also possible to base station and is indicated to UE, this is not restricted.
Base station determines that the mode of at least two PDCCH resources has following two ways, and base station can use any one:
First way:
Base station determines a PUCCH resource from multiple PUCCH resources, and the PUCCH resource of UCI is sent for UE.For example, really Determining first PUCCH resource in PUCCH resource set 01 is the PUCCH resource that UE sends UCI.If base station passes through PDCCH's Frequency domain resource is hidden to show the serial number in PUCCH resource set 01 for indicating the PUCCH resource, then base station can be using in S303 Method determines the frequency domain resource starting CCE serial number and the polymerization of each PDCCH of each PDCCH at least two PDCCH Rank, so that the UE that the frequency domain resource of each of at least two PDCCH PDCCH determines is used to send the PUCCH money of UCI Source is identical.Specific to calculation formula, then have:
For example, at least two PDCCH resource be N number of PDCCH resource in first PDCCH resource and the last one PDCCH resource, in order to make the frequency domain resource of first PDCCH and the last one PDCCH are hidden to show instruction PUCCH resource set 01 In first PUCCH resource, then can regulate and control first PDCCH frequency domain resource be CCE0-CCE1 (L=2), and regulation The frequency domain resource of the last one PDCCH is CCE2 (L=1).
The second way:
Base station does not need to determine that UE sends the PUCCH resource of UCI from multiple PUCCH resources in advance, but by least First PDCCH resource in two PDCCH determines the resource of PDCCH other at least two PDCCH, so that should The PUCCH resource that the UE that the frequency domain resource of each of at least two PDCCH PDCCH determines is used to send UCI is identical.Example Such as, which is first PDCCH resource and the last one PDCCH resource in N number of PDCCH resource, base The hidden serial number in PUCCH resource set 01 for showing the instruction PUCCH resource of frequency domain resource stood through PDCCH, then base station can To determine the frequency domain resource of first PDCCH according to normal dispatching algorithm, for example, the frequency domain resource of first PDCCH is CCE2-CCE3 (L=2), then, base station determine its hidden PUCCH resource for showing instruction according to the frequency domain resource of first PDCCH Serial number 1, then base station determines the serial number 1 of the hidden PUCCH resource for showing instruction of the frequency domain resource of the last one PDCCH, base station The frequency domain resource that can determine the last one PDCCH is CCE4-CCE7 (L=4).
Base station determines that the mode of at least two PDSCH resources is identical as the mode of at least two PDCCH resources is determined, herein It repeats no more.
After base station determines N number of PDCCH resource or N number of PDSCH resource, then sent in corresponding resource to UE corresponding Information.Specifically, base station can be one of the following two kinds situation to the mode that UE sends corresponding information.It is logical with base station Cross N number of PDCCH resource to UE send DCI for, base station can be determine a PDCCH resource after, in the PDCCH resource DCI is sent, is then determining next PDCCH resource；Alternatively, base station is also possible to first determine each of N number of PDCCH resource After PDCCH resource, DCI successively then is being sent in N number of PDCCH resource, this is not restricted.
It should be noted that principle and the downlink resource of the processing mode of base station are when downlink resource is PDSCH resource It is identical when PDCCH resource, therefore, no longer downlink resource is carried out individually for the case where PDSCH resource in the embodiment of the present application Description.
S602:UE receives the K downlink information that base station is sent.
For convenience of description, it is illustrated so that downlink resource is PDCCH resource, downlink information is DCI as an example below.
UE is empty in public search space (Common Search Space, CSS) and specific search by way of blind examination Between scan in (Specific Search Space, SSS), to obtain the DCI of base station transmission.
It should be noted that, although base station has sent N number of DCI to UE, but UE may be without all receiving, for example, UE N-1 DCI is received only, therefore, K is less than or equal to N, and K is more than or equal to zero positive integer
After UE receives the DCI of base station transmission, then by one at least two PDCCH resources of carrying DCI, really Determine the PUCCH resource for sending UCI.It is which specific resource, UE in N number of PDCCH resource according at least two PDCCH resources It determines that the mode of the PUCCH resource for sending UCI is different, is broadly divided into following four kinds of modes.
The first method of determination, at least two first downlink resources are first PDCCH money in N number of PDCCH resource The last one PDCCH resource in source and N number of PDCCH resource；Or at least two first downlink resource be N number of PDCCH money First PDCCH resource, penultimate PDCCH resource and the last one PDCCH resource in source:
S603: if first downlink information sent in K downlink information comprising base station, UE believes according to first downlink It ceases occupied downlink resource and determines PUCCH resource for sending UCI.
After UE receives K DCI, then (downlink is indexed according to the counter downlink task carried in DCI Assignment index, DAI) and/or total DAI determine whether to receive first DCI of base station transmission.Below with Illustrate for counter DAI.Specifically, when UE receives first DCI, obtain the counter DAI's in the DCI Value, when the value is 1, then it represents that the DCI is first DCI that base station is sent, then, then receive first of UE The value of the PUCCH resource indicator for including in DCI is determined for where sending the PUCCH resource of UCI Then PUCCH resource set is determined according to the occupied PDCCH resource of first DCI received for sending UCI's Serial number of the PUCCH resource in the PUCCH resource set.Due to PDCCH resource include the frequency domain resource of PDCCH, time-domain resource, Any one or more in code domain resource and port numbers, and base station can show instruction according to the resource progress made an appointment is hidden Or base station can indicate to have used to UE which kind of resource carry out it is hidden show instruction, therefore, UE after the corresponding PDCCH resource of acquisition, The serial number of PUCCH resource is then determined according to the method recorded in S601, details are not described herein.
S604: if first downlink information not sent comprising base station in K downlink information, UE believes according to the K downlink The occupied downlink resource of the downlink information finally received in breath determines the PUCCH resource for sending UCI.
When UE receives first DCI, the value of the counter DAI in the DCI is obtained, when the value is not 1, example For example 2, then it represents that first DCI that UE is received is second DCI that base station is sent.Then, UE is then more according to receiving The occupied PDCCH resource of any one DCI and the last one DCI determines the PUCCH resource for sending UCI in a DCI, Specific to determine that method is identical with S603, details are not described herein.
It should be noted that UE is according to whether first DCI for receiving base station transmission is determined and executed S603 or S604, i.e., S603 and S604 selects one and is executed.In Fig. 6, by taking S604 is optional step as an example.
If base station is when basis is indicated to UE and determines multiple PDCCH resources for sending the PUCCH resource of UCI, control is fallen The PUCCH resource of implicit instruction, implicit with first PDCCH resource and the last one PDCCH resource in second PDCCH of number The PUCCH resource of instruction is different, then the method in the embodiment of the present application further include:
S605:UE, which is determined, loses the last one downlink information that base station is sent.
In at least two first downlink resources include first PDCCH resource in N number of PDCCH resource and this is N number of The last one PDCCH resource in PDCCH resource, and UE determines first DCI for receiving base station transmission by S603, if then UE is determined with UE according to the last one DCI received according to the PUCCH resource for sending UCI that first DCI is determined PUCCH resource for sending UCI is different, then UE, which is determined, loses the last one DCI that base station is sent, since UE is lost finally One DCI can not naturally also receive the last one lower line number that base station is sent from the last one PDSCH resource that base station indicates According to therefore, when UE is when sending UCI, the NACK response to the last one downlink data of the loss can be increased, in this way, base Blind decoding can then not had to when receiving the UCI by, which standing, just can determine that UE is lost the last one downlink data.
It should be noted that S605 is optionally, that is, to be not required execution, that is, UE can not know whether lose most The latter DCI, if i.e. UE is lost the last one DCI, but without being determined using the method for S605, then UE when sending UCI, The NACK response to the last one downlink data of the loss cannot be sent, is i.e. has been lacked in UCI under the last one The bit number of the acknowledgement bit of row data, the bit number of the UCI UCI that receives more expected than base station is few, therefore base station needs Needing to carry out a blind decoding when receiving the UCI can determine that UE is lost the last one downlink data.
S606:UE sends UCI in PUCCH resource.
After UE receives K DCI, then K PDSCH resource is determined according to K DCI, then in the K PDSCH resource The upper downlink data for receiving base station and sending, and ACK/ corresponding with each PDSCH resource is generated according to the downlink data received NACK response.For example, UE can be carried in UCI using K bit and the downlink data in this K PDSCH resource ACK/NACK response, wherein each bit characterizes the ACK/NACK response to corresponding downlink data, for example, the 1st bit For the ACK/NACK response of the downlink data in the PDSCH resource to the first DCI instruction received, the 2nd bit is pair The ACK/NACK response of downlink data in the PDSCH resource of the second DCI instruction received, and so on.Certainly, this It is a kind of example of UE feeding back ACK/NACK response, to UE, how feeding back ACK/NACK response is not limited in this application.
Second of method of determination, referring to FIG. 8, at least two first downlink resources are first in N number of PDCCH resource Second PDCCH resource in a PDCCH resource and N number of PDCCH resource:
S607: if first downlink information sent in K downlink information comprising base station, UE believes according to first downlink It ceases occupied downlink resource and determines PUCCH resource for sending ascending control information UCI.
S608: if first downlink information not sent comprising base station in K downlink information, UE is according to the K downlink The second occupied downlink resource of downlink information sent by base station received in information is determined for sending UCI's PUCCH resource.In fig. 8, S608 is optional.
When UE receives the value of the counter DAI in first DCI, when the value is not that 1, UE determination does not receive First DCI that base station is sent, then UE determines whether the value is 2, if the value is 2, then it represents that the DCI is what base station was sent Second DCI, then UE determines the PUCCH resource for sending UCI according to the occupied PDCCH resource of the DCI and DCI, Specific to determine that method is identical with S603, details are not described herein.
It should be noted that UE is according to whether first DCI for receiving base station transmission is determined and executed S607 or S608, i.e., S607 and S608 selects one and is executed.
S609:UE sends UCI in PUCCH resource.
S609 is identical as S606, and details are not described herein.It should be noted that UE can be according to the counter DAI in DCI Determine the DCI being currently received is which DCI that base station is sent, then the counter DAI for first DCI that UE is received is When 3, then UE determines that first DCI and second DCI for not receiving base station transmission, i.e. UE do not receive base station and pass through this at least The DCI that any one PDCCH in two PDCCH is sent, then UE, which can choose, does not send UCI.
The third method of determination, at least two first downlink resources are most latter two PDCCH in N number of PDCCH resource When resource, UE is then directly according to the shared of any one DCI in the K DCI received and the last one DCI received PDCCH resource determines the ascending resource for sending UCI.
In this case, if base station, which is indicated to UE in basis, determines multiple PDCCH for sending the PUCCH resource of UCI When resource, the PUCCH resource of implicit instruction in third last PDCCH is controlled, with most latter two PDCCH resource implicit instruction PUCCH resource it is different, then the method in the embodiment of the present application further include:
If UE is according to the penultimate DCI that the receives PUCCH resource for sending UCI determined and UE according to reception To the PUCCH resource for sending UCI that determines of the last one DCI it is different, then UE determines last for losing that base station sends Therefore a DCI when UE is when sending UCI, can increase the NACK response to the last one downlink data of the loss, thus Base station, which can then not have to blind decoding when receiving the UCI, just can determine that UE is lost the last one downlink data.
4th kind of mode, referring to FIG. 9, at least two first downlink resources are first in N number of PDCCH resource PDCCH resource, second PDCCH resource and the last one PDCCH resource:
S610: if first downlink information sent in K downlink information comprising base station, UE believes according to first downlink It ceases occupied downlink resource and determines PUCCH resource for sending ascending control information UCI.
S611: if first downlink information not sent comprising base station in K downlink information, UE is according to the K downlink The second occupied downlink resource of downlink information sent by base station received in information is determined for sending UCI's PUCCH resource；
S610-S611 is identical as S607-S608, and details are not described herein.
S612: if UE determines first DCI and second DCI for not receiving base station transmission, basis is received most The occupied downlink resource of the latter DCI determines the PUCCH resource for sending UCI.
When UE is by the value of the counter DAI in DCI, determine first DCI for not receiving base station transmission and 2nd DCI, then UE is according to any one DCI in the multiple DCI received and the occupied PDCCH resource of the last one DCI Determine the PUCCH resource for sending UCI, specific to determine that method is identical with S603, details are not described herein.
It should be noted that if base station, which is indicated to UE in basis, determines multiple PDCCH for sending the PUCCH resource of UCI When resource, the PUCCH resource for controlling each of N number of PDCCH PDCCH resource implicit instruction is all the same, then UE can basis The occupied PDCCH resource of any one DCI received determines the PUCCH resource for sending UCI.
