2, the running time-frequency resource position that the network equipment indicates in above-mentioned DCI is sent out with the configuration parameter indicated in DCI to terminal Send corresponding data；Terminal receives the data that the network equipment is sent with relevant parameter in corresponding position.

3, terminal is after receiving the data, it is also necessary to feed back hybrid automatic repeat-request (Hybrid to the network equipment Automatic Repeat reQuest, HARQ)-data validation information, HARQ-ACK information can also be claimed.Wherein, HARQ is By forward error correction (Forward Error Correction, FEC) and automatic repeat request (Automatic Repeat ReQuest, ARQ) combine and the technology that is formed.FEC enables the terminal to correct a part of mistake by addition redundancy Accidentally, to reduce the number of re-transmission.For the mistake that FEC can not be corrected, terminal can be retransmitted by the ARQ mechanism request network equipment Data.Terminal uses error-detecging code, and usually cyclic redundancy check (Cyclic Redundancy Check, CRC) verifies, to examine Survey whether the data packet received malfunctions.If error-free, terminal can send the data validation information (ACK) an of affirmative to hair Sending end after the network equipment receives ACK, can then send next data packet.If error, terminal can abandon the data packet, And the data validation information (NACK) for sending a negative after the network equipment receives NACK, can be retransmitted identical to the network equipment Data.

Above-mentioned process may refer to shown in Fig. 2, and Fig. 2 is between one embodiment of the application network equipment provided and terminal The schematic diagram of downlink data transmission process, wherein PDCCH carries DCI, and PDSCH carries downlink data.In some embodiments In, terminal may exist the corresponding data validation information of multiple PDSCH when to network equipment feedback data confirmation message It is fed back in same time domain resource.As shown in figure 3, Fig. 3 is that the terminal that one embodiment of the application provides is fed back to the network equipment The schematic diagram of the corresponding data validation information of multiple PDSCH, by taking 3 PDSCH as an example, 3 PDSCH are needed in same time domain Fig. 3 Resource feedback data confirmation message is not using space division multiplexing and is being based on the biography of code block group (code block group, CBG) In the case where the technologies such as defeated, the size of the code book of corresponding data validation information is exactly 3 bits at this time, and the sequence of 3 bits can Being determined according to the received sequence of PDSCH.Wherein it is determined that the corresponding data validation information of which PDSCH is in same time domain The detailed process that resource is fed back to the network equipment are as follows: according to the time interval between PDSCH and corresponding data validation information, with And PDSCH and PDCCH time interval and each time slot in the occupied symbol of PDSCH position candidate, determine PDCCH candidate Then the time slot of position searches whether that there are PDCCH to monitor chance in the time slot of these PDCCH position candidates, then determines The data for finding PDSCH corresponding to PDCCH monitoring chance determine that information can be fed back to the network equipment simultaneously.

In 5G system, the network equipment is communicated with terminal using BWP, as shown in figure 4, Fig. 4 is with PDSCH and PDCCH Time interval be 0 time slot for, in time slot 1, the downlink BWP of activation is jumped on downlink BWP1 from downlink BWP0, wherein In time slot 1, the network equipment sends PDCCH to terminal on downlink BWP0, which dispatches the PDSCH of same time slot, so In time slot 1, the network equipment sends PDSCH to terminal on downlink BWP1.But the scheme of the prior art is to send data When confirmation message, the time slot (such as time slot 0,1,2) of the PDCCH position candidate on the downlink BWP (i.e. downlink BWP1) of activation Interior lookup PDCCH monitors chance.If monitoring chance without PDCCH on downlink BWP1 in time slot 1, it is believed that The corresponding data validation letter of PDSCH without effective PDSCH transmission in time slot 1, then not into network equipment feedback slot 1 Breath.But it will be seen that be in time slot 1 on downlink BWP0 there is PDCCH to monitor chance (PDSCH of time slot 1 is by BWP0 On time slot 1 in PDCCH scheduling).Therefore, this in the prior art activated when sending data validation information under PDCCH is searched on row BWP (only in a downlink BWP) and monitors the problem of chance causes under-enumeration PDCCH to monitor chance, to cause The problem of data validation information of some downlink datas is not fed back to the network equipment.The following each embodiments of the application can solve this One technical problem.

Fig. 5 is the flow chart for the communication means that one embodiment of the application provides, as shown in figure 5, the method for the present embodiment can To be applied to terminal, the network equipment also can be applied to, the method for the present embodiment may include:

S501, according to the first time-domain resource and the first information, determine the second time-domain resource.

Wherein, the first time-domain resource is the time-domain resource of PDSCH position candidate (PDSCH candidate), the second time domain Resource is the time-domain resource of PDCCH position candidate (PDCCH candidate).And the first information includes: the candidate bit of PDSCH The time interval with the position candidate of PDCCH is set, alternatively, the candidate bit of the position candidate of first information instruction PDSCH and PDCCH The time interval set.

The present embodiment, terminal and/or the network equipment determine that the second time domain provides according to the first time-domain resource and the first information Source.Such as: the time-domain resource of PDSCH position candidate is time slot 2, the time interval of PDSCH position candidate and PDCCH position candidate For 1 time slot, it is determined that the time-domain resource of PDCCH position candidate is time slot (2-1), i.e. time slot 1.

S502, in the corresponding time range of second time-domain resource, search PDCCH at least one downlink BWP Monitor chance.

In the present embodiment, after determining the second time-domain resource, terminal and/or the network equipment are corresponding in the second time-domain resource In time range, PDCCH is searched at least one downlink BWP and monitors chance.Since the present embodiment is more than in transmission data PDCCH, which is searched, on the downlink BWP (i.e. only in a downlink BWP) activated when confirmation message monitors chance, but at least one PDCCH is searched on downlink BWP and monitors chance, reduces the phenomenon that under-enumeration PDCCH monitors chance.

In some embodiments, above-mentioned at least one downlink BWP include: the network equipment configured to the terminal it is all Downlink BWP.It is, terminal and/or the network equipment be after determining the second time-domain resource, in the second time-domain resource corresponding time PDCCH, which is searched, in range, on all downlink BWP from the network equipment to the terminal that configure in monitors chance.If the network equipment to All lower BWP of terminal configuration include: downlink BWP0, downlink BWP1, downlink BWP2, for situation shown in Fig. 4, the present embodiment Terminal and/or the network equipment can be searched on downlink BWP0, downlink BWP1 and downlink BWP2 PDCCH monitor chance, this Sample can search the PDCCH on the downlink BWP1 missed in technology till now and monitor chance.Therefore, the present embodiment can avoid leakage Look into the case where PDCCH monitors chance.

In some embodiments, at least one downlink BWP are as follows: the network equipment is configured to the terminal, and All downlink BWP activated in the corresponding time range of second time-domain resource.It is, terminal and/or the network equipment After determining the second time-domain resource, in the corresponding time range of the second time-domain resource, configured in the network equipment to the terminal, And the downlink BWP activated in the corresponding time range of the second domain resource searches PDCCH and monitors chance.If the network equipment to All lower BWP of terminal configuration include: downlink BWP0, downlink BWP1, downlink BWP2, for situation shown in Fig. 4, if when second Domain resource is time slot 1 shown in Fig. 4, since the downlink BWP activated in time slot 1 jumps to downlink BWP1 by downlink BWP0, In the corresponding time range of time slot 1, the downlink BWP that activated is downlink BWP0 and downlink BWP1, then the terminal of the present embodiment and/ Or the network equipment can search PDCCH on downlink BWP0 and downlink BWP1 and monitor chance, can thus search till now PDCCH on the downlink BWP1 missed in technology monitors chance.Therefore, the present embodiment can avoid under-enumeration PDCCH and monitor chance Situation.

It follows that the present embodiment is by determining the second time-domain resource according to the first time-domain resource and the first information；It is described First time-domain resource is the time-domain resource of PDSCH position candidate, and the second time-domain resource is the time-domain resource of PDCCH position candidate, The first information include or instruction PDSCH position candidate and PDCCH position candidate time interval；Then it is provided in second time domain PDCCH, which is searched, in the corresponding time range in source, on all downlink BWP from the network equipment to the terminal that configure in monitors chance, Alternatively, the network equipment configured to the terminal and activated in the corresponding time range of second time-domain resource PDCCH is searched on all downlink BWP and monitors chance, can be found the corresponding all PDCCH of PDSCH in this way and be monitored chance, keep away The case where exempting from the phenomenon that under-enumeration PDCCH monitors chance, the data validation information of downlink data avoided to miss, to improve communication matter Amount.

In some embodiments, a kind of possible implementation of above-mentioned S502 may include: to provide in second time domain In time-domain resource in corresponding at least one downlink BWP in source on each downlink BWP, looked on each downlink BWP PDCCH is looked for monitor chance.

Wherein, subcarrier spacing is different, and correspondingly, the time span of time-domain resource unit is not also identical.Therefore, it is above-mentioned extremely The subcarrier spacing of a few downlink BWP may be not exactly the same, this makes the corresponding time-domain resource of at least one downlink BWP The time span of unit is different.Such as: if the subcarrier spacing of downlink BWP0 is 15KHz, the subcarrier spacing of downlink BWP1 is 30KHz, then the time span of the corresponding time-domain resource unit of downlink BWP0 is that the time of the time-domain resource unit of downlink BWP1 is long 2 times of degree.If the subcarrier spacing of downlink BWP0 is 30KHz, the subcarrier spacing of downlink BWP1 is 15KHz, then downlink BWP0 The time span of corresponding time-domain resource unit is 0.5 times of the time span of the time-domain resource unit of downlink BWP1.Therefore, exist Same time is not identical in the time-domain resource on downlink BWP0 and the time-domain resource on downlink BWP1.

So terminal and/or the network equipment are needed when at least one downlink BWP searches PDCCH and monitors chance by second Time-domain resource is converted to the time-domain resource at least one downlink BWP on each downlink BWP, then on each downlink BWP Time-domain resource in, on each downlink BWP search PDCCH monitor chance.Wherein, terminal and/or the network equipment determine Time-domain resource at least one downlink BWP on each downlink BWP for example may include: that terminal and/or the network equipment determine institute The length of the time-domain resource unit of each downlink BWP at least one downlink BWP is stated, it is then corresponding according to the second time-domain resource The length of the time-domain resource unit of the length of time-domain resource unit and each downlink BWP, determines second time-domain resource Time-domain resource on corresponding each downlink BWP.Wherein, the time-domain resource unit in the present embodiment can be time slot, but The present embodiment is not limited to this, and can also divide time-domain resource in other ways.By taking time-domain resource unit is time slot as an example, if The length of the corresponding time-domain resource unit of second time-domain resource is the length of the time-domain resource unit on one of downlink BWP 2 times, if the second time-domain resource is time slot 1, the corresponding time-domain resource on downlink BWP of second time-domain resource is time slot 2 and time slot 3, such as shown in Figure 6.

Optionally, terminal and/or the network equipment can determine each according to the subcarrier spacing of each downlink BWP The length of the time-domain resource unit of downlink BWP.

Wherein, which includes corresponding time-domain resource on the downlink BWP of the first activation, this first swashs Downlink BWP living can refer to the downlink BWP being active when terminal feedback data confirmation message.

In some embodiments, it if the various embodiments described above are executed by terminal, in terminal before executing above-mentioned S501, also connects PDSCH is received, such as receives the PDSCH that the network equipment is sent, then basis is used for transmission the corresponding data validation letter of the PDSCH M kind time interval between the time-domain resource of breath and the PDSCH and the data validation information, when determining described first Domain resource.

In some embodiments, if the various embodiments described above are executed by the network equipment, the network equipment execute above-mentioned S501 it Before, also transmission PDSCH, such as PDSCH is sent to terminal, then basis is used for transmission the corresponding data validation letter of the PDSCH M kind time interval between the time-domain resource of breath and the PDSCH and the data validation information, when determining described first Domain resource.

Wherein, above-mentioned M is the integer more than or equal to 1；Wherein it is determined that first time-domain resource include: first Corresponding time-domain resource on the downlink BWP of activation.The downlink BWP of first activation can refer to terminal feedback data confirmation letter The downlink BWP being active when breath.The corresponding data validation information of PDSCH passes through the uplink being active BWP transmission, the time-domain resource for being used for transmission the corresponding data validation information of PDSCH can consider including the uplink in the first activation At when the upper corresponding time-domain resource of BWP, uplink BWP of first activation can refer to terminal feedback data confirmation message In the uplink BWP of state of activation.And according to the time-domain resource that is used for transmission the corresponding data validation information of PDSCH and above-mentioned M kind time interval, the first time-domain resource of acquisition include: corresponding time-domain resource on the downlink BWP of the first activation.

In some embodiments, terminal and/or the network equipment, according to being used for transmission the corresponding data validation of the PDSCH M kind time interval between the time-domain resource of information and the PDSCH and the data validation information, determines described first Time-domain resource, a kind of implementation are as follows:

For every kind of time interval in the M kind time interval, if described be used for transmission the corresponding data of the PDSCH The time-domain resource of confirmation message is that Q kind time interval described in the n-th time-domain resource unit and the M kind time interval is K_1,QA time-domain resource unit, it is determined that first time-domain resource includes (n-K_1,Q) time-domain resource unit.

Wherein, first time-domain resource includes M time-domain resource unit, and the Q is the positive integer less than or equal to M.

Since time interval has M kind, so the n-th time-domain resource unit subtracts each other with M kind time interval, M can be obtained not Same time-domain resource unit.If n is equal to 3, M and is equal to 3, i.e. the n-th time-domain resource unit is the 3rd time slot, i.e. time slot 3, M kind time Interval may include: 1 time slot, 2 time slots, 3 time slots, then the first time-domain resource obtained is time slot 0, time slot 1, time slot 2, As shown in Figure 7.

Wherein, the row format up and down in each time-domain resource unit indicates to provide in each time-domain resource unit for the time domain of uplink Source and time-domain resource for downlink transfer, if PDSCH position candidate has weight with the time-domain resource for uplink It is folded, then illustrate that the PDSCH position candidate is not effective PDSCH position candidate；Otherwise, which is effective PDSCH position candidate.

Then terminal and/or the network equipment determine the first information according to the effective PDSCH position candidate of the J kind. In the present embodiment, every kind of PDSCH position candidate, and there are corresponding relationships for time interval, and therefore, terminal and/or the network equipment exist After determining the effective PDSCH position candidate of J kind, determine between the J kind effective PDSCH position candidate institute corresponding time Every the corresponding time interval of J kind effective PDSCH position candidate institute is then determined as PDSCH position candidate and PDCCH The time interval of position candidate.

Wherein, the I kind PDSCH position candidate configured in each time-domain resource unit on the downlink BWP of the first activation And corresponding time interval K₀As shown in Table 1.Wherein, in table one by taking time-domain resource unit is time slot as an example, PDSCH is waited Bit selecting is set by primary sign and symbol lengths and is indicated.The table an example is if any 4 column × I row.The content wherein respectively arranged is sequence respectively Number, time interval K₀It is worth, primary sign and symbol lengths in each time slot, map type.The table one can be pre-defined , it can also be configured with the network equipment to terminal.

Table one

Wherein, table one is by taking I is equal to 4 as an example, wherein the K of every row₀Value, primary sign and symbol lengths and map type It is all example, the present embodiment is not limited to this.The K of every row₀It is all 0 (i.e. time interval is 0 time slot), map type can be with Referring to description in the prior art.PDSCH position candidate in each time slot corresponding to each serial number in table one (i.e. primary sign and Symbol lengths) with the row format up and down in each time slot as shown in figure 8, if row format indicates first 10 in each time slot up and down Symbol (symbol 0-9) is used for downlink transfer, and rear 4 symbols (symbol 10-13) are used for uplink.Then it is found that serial number 0 and serial number 1 corresponding PDSCH position candidate meets row format up and down, and serial number 2 and the corresponding PDSCH position candidate of serial number 3 are not met up and down Row format.Then by the K in serial number 0 and serial number 1₀Value is determined as the time-domain resource and PDCCH candidate bit of PDSCH position candidate The time interval for the time-domain resource set.

In some embodiments, the first time-domain resource includes R sub- time-domain resources, between the time of the first information instruction It is divided into T kind, a kind of implementation of above-mentioned S501 may include:

When for every kind in the sub- time-domain resource of each of the R sub- time-domain resource and the T kind time interval Between be spaced, if H sub- time-domain resources are located at m in the R sub- time-domain resources_vIn time-domain resource unit and the T kind S kind time interval in time interval is K_0,S, then the terminal determines that second time-domain resource includes (m_v-K_0,S) when Domain resource unit；Wherein, the H is the positive integer less than or equal to R, and the S is the positive integer less than or equal to T, and the v is positive whole Number.

Optionally, which is continuous at least two symbol in the time-domain resource unit.

Below by taking time-domain resource unit is time slot as an example, the first time-domain resource includes time slot 0, time slot 1, time slot 2, according to every Effective PDSCH position candidate in a time slot, such as in conjunction with shown in table one and Fig. 8, it is known that the symbol 3- symbol 7 in time slot 0 is Sub- time-domain resource, the symbol 5- symbol 9 in time slot 0 are sub- time-domain resource, and the symbol 3- symbol 7 in time slot 1 is sub- time-domain resource, Symbol 5- symbol 9 in time slot 1 is sub- time-domain resource, and the symbol 3- symbol 7 in time slot 2 is sub- time-domain resource, the symbol in time slot 2 Number 5- symbol 9 is sub- time-domain resource, and therefore, the first time-domain resource includes 6 sub- time-domain resources.Wherein, the 1st sub- time-domain resource It is located in time slot 0 for the symbol 3- symbol 7 in time slot 0, since time interval is 0 time slot, may thereby determine that time slot (0- 0), i.e. time slot 0；2nd sub- time-domain resource is that the symbol 5- symbol 9 in time slot 0 is located in time slot 0, since time interval is 0 A time slot may thereby determine that time slot (0-0), i.e. time slot 0；3rd sub- time-domain resource is the symbol 3- symbol 7 in time slot 1 In time slot 1, since time interval is 0 time slot, time slot (1-0), i.e. time slot 1 may thereby determine that；4th sub- time domain money Source is that the symbol 5- symbol 9 in time slot 1 is located in time slot 1, since time interval is 0 time slot, may thereby determine that time slot (1-0), i.e. time slot 1；5th sub- time-domain resource is that the symbol 3- symbol 7 in time slot 2 is located in time slot 2, since time interval is equal For 0 time slot, time slot (2-0), i.e. time slot 2 may thereby determine that；6th sub- time-domain resource is the symbol 5- symbol 9 in time slot 2 In time slot 2, since time interval is 0 time slot, time slot (2-0), i.e. time slot 2 may thereby determine that.Therefore, it can obtain Obtaining the second time-domain resource includes time slot 0- time slot 2.After determining the second time-domain resource, terminal and/or the network equipment are in time slot 0- In the corresponding time range of time slot 2, PDCCH is searched at least one downlink BWP and monitors chance.

Optionally, after terminal and/or the network equipment execute above-mentioned S502, if (the m in second time-domain resource_v- K_0,S) in the corresponding time range of time-domain resource unit, PDCCH is found at least one downlink BWP and monitors chance, Then terminal and/or the network equipment determine that H sub- time-domain resources are effective PDSCH candidate bits in the R sub- time-domain resources It sets.If being found at least one downlink BWP in the time range of time slot 0 and time slot 2 in the second time-domain resource PDCCH monitors chance, then the 1st sub- time-domain resource corresponding with the time slot 0 in the second time-domain resource and the 2nd sub- time-domain resource For effective PDSCH position candidate, and the 5th sub- time-domain resource corresponding with the time slot 2 in the second time-domain resource and the 6th son Time-domain resource is effective PDSCH position candidate.

Optionally, after terminal and/or the network equipment execute above-mentioned S502, if (the m in second time-domain resource_v- K_0,S) in the corresponding time range of time-domain resource unit, do not find PDCCH at least one downlink BWP and monitor machine Meeting, then terminal and/or the network equipment determine that H sub- time-domain resources are not that effective PDSCH is waited in the R sub- time-domain resources Bit selecting is set.If not found at least one downlink BWP in the time range of the time slot 1 in the second time-domain resource PDCCH monitors chance, then the 3rd sub- time-domain resource corresponding with the time slot 1 in the second time-domain resource and the 4th sub- time-domain resource It is not effective PDSCH position candidate.

Wherein, effective PDSCH position candidate, which refers to, is determining semi-static data validation information (HARQ-ACK) code book When, it needs to take into account this PDSCH position candidate in subsequent possible process.For example, passing through reality described herein Example is applied, A effective PDSCH position candidates have finally been determined, then terminal at most needs to feed back A PDSCH to the network equipment Corresponding data validation information, the network equipment need to receive the corresponding data validation information of A PDSCH from terminal.Determining half When static HARQ-ACK code book, after using embodiment described herein, other methods are likely present, it can be further Filter out B (B is less than or equal to A) PDSCH position candidates from the effective PDSCH position candidates of A, final terminal is to network Equipment needs to feed back the corresponding data validation information of B PDSCH, and the network equipment needs to receive the corresponding number of B PDSCH from terminal According to confirmation message.

It is illustrated below with scheme of several specific embodiments to the application.It is below UE with terminal, time-frequency money Source unit is that the time interval of time slot, PDSCH position candidate and PDCCH position candidate is K0, is used for transmission the corresponding number of PDSCH It is K1 according to the time interval between the time-domain resource of confirmation message and the PDSCH, data validation information is HARQ-ACK information, into Row description.Effective PDSCH position candidate can be described as the active position of PDSCH, and effective PDSCH position candidate has been properly termed as The PDSCH transmission position of effect.

In the first embodiment, UE is switched on BWP2 from BWP2 in time slot 1 and works, as shown in Figure 9.UE quilt The value collection for being configured with K1 is combined into { 1,2,3 }.HARQ-ACK information is fed back on time slot 3.The time domain money that UE is configured on BWP2 The table of source distribution is as shown in above-mentioned table one, it can be seen that 4 PDSCH position candidates are configured in each time slot.Each PDSCH The corresponding K0 value of the position candidate (K as in table one₀) it is 0.Structure of time slot in each time slot is as shown in Figure 8.

UE is in time slot 0, in any one time slot of time slot 1 and time slot 2, can obtain effective PDSCH according to the prior art The corresponding position of transmission location, i.e. serial number 0 and serial number 1.Later can in time slot 0, in any one time slot of time slot 1 and time slot 2, According to serial number 0 and the corresponding K0 value of serial number 1, check whether that PDCCH monitors chance.
