In the present embodiment, terminal and/or the network equipment are in the corresponding time range of second running time-frequency resource, not only root According to the second information also according at least one of following: PDCCH listening period, PDCCH monitor deviant and PDCCH listening mode, To determine that prepared PDCCH monitors opportunity.The PDCCH listening period, PDCCH monitor deviant and PDCCH listening mode It may refer to the associated description of the prior art, details are not described herein again.

In a kind of mode, terminal and/or the network equipment can be first in the corresponding time ranges of second running time-frequency resource Interior, according at least one of following: PDCCH listening period, PDCCH monitor deviant and PDCCH listening mode, determine N number of PDCCH monitors opportunity, this process may refer to associated description in the prior art, and details are not described herein again.Then, terminal and/ Or the network equipment determines that G effective PDCCH monitor opportunity, the G is according to the second information from N number of PDCCH monitoring opportunity Integer more than or equal to 1, the N are the integer more than or equal to the G.Such as: if at least one in the PDCCH monitoring opportunity The running time-frequency resource of PDCCH position candidate and the third running time-frequency resource be not be overlapped, then it is assumed that PDCCH monitoring opportunity is effective PDCCH is monitored opportunity, and the data validation information of PDSCH corresponding to the PDCCH monitoring opportunity can be fed back to the network equipment；If should The running time-frequency resource of all PDCCH position candidates is Chong Die with the third running time-frequency resource in PDCCH monitoring opportunity, then it is assumed that should PDCCH monitors opportunity and monitors opportunity for invalid PDCCH, the data validation information of PDSCH corresponding to the PDCCH monitoring opportunity It is not fed back to the network equipment.

Therefore, terminal and/or the network equipment, can be according to the second letters in the corresponding time range of second running time-frequency resource Breath determines that effective PDCCH monitors opportunity, and the effective PDCCH monitoring opportunity determined eliminates Chong Die with third running time-frequency resource PDCCH monitor opportunity, reduce the bit number for the data validation information that terminal is sent to the network equipment, save network provide Source.

In addition, in 5G system, the network equipment is communicated with terminal using BWP, as shown in fig. 7, Fig. 7 with PDSCH with The time interval of PDCCH 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 same time slot PDSCH, so the network equipment sends PDSCH to terminal on downlink BWP1 in time slot 1.But the scheme of the prior art is When sending data validation information, the time slot of the PDCCH position candidate on the downlink BWP (i.e. downlink BWP1) of activation (such as Time slot 0,1,2) in determine that PDCCH monitors opportunity.If monitoring opportunity without PDCCH on downlink BWP1 in time slot 1, It is believed that the corresponding number of PDSCH without effective PDSCH transmission in time slot 1, then not into network equipment feedback slot 1 According to confirmation message.But it will be seen that be in time slot 1 on downlink BWP0 there is PDCCH to monitor opportunity (PDSCH of time slot 1 is By the PDCCH scheduling in the time slot 1 on BWP0).Therefore, this in the prior art when sending data validation information Searching PDCCH on the downlink BWP (only in a downlink BWP) of activation and monitoring opportunity will cause when missing effective PDCCH and monitoring The problem of machine, thus the problem of causing the data validation information of some downlink datas not feed back to the network equipment.The application is following Each embodiment can solve this technical problem.

Fig. 8 is the flow chart for the communication means that another embodiment of the application provides, as shown in figure 8, the method for the present embodiment It can be applied to terminal, also can be applied to the network equipment, the method for the present embodiment may include:

S801, according to the first running time-frequency resource and the first information, determine the second running time-frequency resource.

In the present embodiment, the specific implementation process of S801 may refer to the associated description in embodiment illustrated in fig. 6, herein not It repeats again.

S802, in the corresponding time range of second running time-frequency resource, according to the second information at least one BWP really Fixed effective PDCCH monitors opportunity.

Terminal and/or the network equipment are after determining the second running time-frequency resource, in the corresponding time range of the second running time-frequency resource, Determine that effective PDCCH monitors opportunity not only according to the second information but also at least one BWP.Optionally, terminal and/ Or the network equipment is in the corresponding time range of the second running time-frequency resource, it can be according to the second information and at least one of following: PDCCH listening period, PDCCH monitor deviant and PDCCH listening mode, and effective PDCCH is determined at least one BWP Monitoring opportunity.Such as: terminal and/or the network equipment are in the corresponding time range of the second running time-frequency resource, according to as follows at least one : PDCCH listening period, PDCCH monitor deviant and PDCCH listening mode, and N number of PDCCH is determined at least one BWP Then monitoring opportunity determines that G effective PDCCH monitor opportunity according to the second information from N number of PDCCH monitoring opportunity.

Therefore, terminal and/or the network equipment are in the corresponding time range of the second running time-frequency resource, according to the second information extremely Determine that effective PDCCH monitors opportunity on a few downlink BWP.Since the present embodiment is more than when transmitting data validation information Determine that PDCCH monitors opportunity on the downlink BWP (i.e. only in a downlink BWP) of activation, but at least one downlink BWP, It determines that effective PDCCH monitors opportunity according to the second information, not only reduces the data validation letter that terminal is sent to the network equipment The bit number of breath, saves Internet resources, also reduces the phenomenon that effective PDCCH of under-enumeration monitors opportunity.

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 running time-frequency resource, in the second running time-frequency resource corresponding time Determine that effective PDCCH is monitored in range, on all downlink BWP for configuring in the network equipment to the terminal according to the second information Opportunity.If all lower BWP that the network equipment is configured to terminal include: downlink BWP0, downlink BWP1, downlink BWP2, for Fig. 7 institute The case where showing, the terminal and/or the network equipment of the present embodiment can be according to the second information in downlink BWP0, downlink BWP1 and downlink Determine that effective PDCCH monitors opportunity, can thus determine having on the downlink BWP1 missed in the prior art on BWP2 The PDCCH of effect monitors opportunity.Therefore, the present embodiment not only reduces the ratio for the data validation information that terminal is sent to the network equipment Special number, saves Internet resources, also can avoid missing the case where effective PDCCH monitors opportunity.

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 running time-frequency resource.It is, terminal and/or the network equipment After determining the second running time-frequency resource, in the corresponding time range of the second running time-frequency resource, according to the second information, in the network equipment It is configured to the terminal and the downlink BWP activated in the corresponding time range of the second running time-frequency resource determines effective PDCCH Monitoring opportunity.If all lower BWP that the network equipment is configured to terminal include: downlink BWP0, downlink BWP1, downlink BWP2, for Situation shown in Fig. 7, if the second running time-frequency resource is time slot 1 shown in Fig. 7, since the downlink BWP activated in time slot 1 is by downlink BWP0 jumps to downlink BWP1, and in the corresponding time range of time slot 1, the downlink BWP activated is downlink BWP0 and downlink BWP1, then the terminal of the present embodiment and/or the network equipment can determine on downlink BWP0 and downlink BWP1 according to the second information Effective PDCCH monitors opportunity, can thus determine the effective PDCCH prison on the downlink BWP1 missed in the prior art Listen opportunity.Therefore, the present embodiment not only reduces the bit number for the data validation information that terminal is sent to the network equipment, saves Internet resources also can avoid missing the case where effective PDCCH monitors opportunity.

It follows that the present embodiment is by determining the second running time-frequency resource according to the first running time-frequency resource and the first information；It is described First running time-frequency resource is the running time-frequency resource of PDSCH position candidate, and the second running time-frequency resource is the running time-frequency 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-frequency In the corresponding time range in source, there is determination on all downlink BWP for being configured in the network equipment to the terminal according to the second information The PDCCH of effect monitors opportunity, alternatively, according to the second information the network equipment configured to the terminal and at described second Determine that effective PDCCH monitors opportunity on all downlink BWP activated in the corresponding time range of frequency resource, it in this way can be true It makes the corresponding all effective PDCCH of PDSCH and monitors opportunity, not only reduce the data validation that terminal is sent to the network equipment The bit number of information, saves Internet resources, also avoids missing the phenomenon that effective PDCCH monitors opportunity, avoids downlink data Data validation information the case where missing, improve communication quality.

In some embodiments, a kind of possible implementation of above-mentioned S802 may include: to provide in second time-frequency In running time-frequency resource in corresponding at least one downlink BWP in source on each downlink BWP, according to the second information described each Determine that effective PDCCH monitors opportunity on downlink BWP.

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, In 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 determine that effective PDCCH is monitored at least one downlink BWP according to the second information When opportunity, need to be converted to the second running time-frequency resource into the running time-frequency resource at least one downlink BWP on each downlink BWP, then In the running time-frequency resource on each downlink BWP, effective PDCCH is determined on each downlink BWP according to the second information Monitoring opportunity.Wherein, terminal and/or the network equipment determine the running time-frequency resource example at least one downlink BWP on each downlink BWP Time-domain resource list may include: each downlink BWP at least one downlink BWP as described in terminal and/or the network equipment determine The length of member, then according to the length of the corresponding time-domain resource unit of the second running time-frequency resource and each downlink BWP when The length of domain resource unit determines the running time-frequency resource on the corresponding each downlink BWP of second running time-frequency resource.Wherein, originally Time-domain resource unit in embodiment can be time slot, but the present embodiment is not limited to this, and can also be divided in other ways Time-domain resource.By taking time-domain resource unit is time slot as an example, if the length of the corresponding time-domain resource unit of the second running time-frequency resource is it In 2 times of length of time-domain resource unit on a downlink BWP, if the second running time-frequency resource is located in time slot 1, this second when The corresponding running time-frequency resource on downlink BWP of frequency resource is located in time slot 2 and time slot 3, such as shown in Figure 9.

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 running time-frequency 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, if the various embodiments described above are executed by terminal, terminal execute above-mentioned S601 or S801 it Before, also reception PDSCH, such as the PDSCH that the network equipment is sent is received, then basis is used for transmission the corresponding number of the PDSCH According to the M kind time interval between the running time-frequency resource of confirmation message and the PDSCH and the data validation information, institute is determined State the first running time-frequency resource.

In some embodiments, if the various embodiments described above are executed by the network equipment, the network equipment execute above-mentioned S601 or Before S801, also transmission PDSCH, such as PDSCH is sent to terminal, then basis is used for transmission the corresponding data of the PDSCH M kind time interval between the running time-frequency resource of confirmation message and the PDSCH and the data validation information, determine described in First running time-frequency resource.

Wherein, above-mentioned M is the integer more than or equal to 1；Wherein it is determined that first running time-frequency resource include: first Corresponding running time-frequency 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 running time-frequency 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 running time-frequency 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 running time-frequency resource that is used for transmission the corresponding data validation information of PDSCH and above-mentioned M kind time interval, the first running time-frequency resource of acquisition include: corresponding running time-frequency 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 running time-frequency resource of information and the PDSCH and the data validation information, determines described first Running time-frequency 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 running time-frequency resource of confirmation message is located in the n-th time-domain resource unit and between the Q kind time described in the M kind time interval It is divided into K_1,QA time-domain resource unit, it is determined that first running time-frequency resource includes (n-K_1,Q) time-domain resource unit.

Wherein, first running time-frequency 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 10.

Optionally, which can be predetermined, be also possible to be configured from the network equipment to the terminal 's.

In some embodiments, terminal and/or the network equipment are also held lower as follows before executing S601 or S801:

Terminal and/or the network equipment are according to the I configured in each time-domain resource unit on the downlink BWP of the first activation Row format up and down in kind PDSCH position candidate and each time-domain resource unit, from the I kind PDSCH position candidate really Determine the effective PDSCH position candidate of J kind, the I is the integer more than or equal to 1, and the J is the integer less than or equal to I.It should The downlink BWP of first activation can refer to the downlink BWP being active when terminal feedback data confirmation message.I.e. originally The terminal and/or the network equipment of embodiment are upper and lower in determining and each time-domain resource unit from I kind PDSCH position candidate The PDSCH position candidate that row format does not conflict, these PDSCH position candidates determined are known as effective PDSCH position candidate. 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-frequency of uplink Source and running time-frequency resource for downlink transfer, if PDSCH position candidate has weight with the running time-frequency 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, there are corresponding relationships with time interval for every kind of PDSCH position candidate, and therefore, terminal and/or the network equipment are true After determining the effective PDSCH position candidate of J kind, the corresponding time interval of the effective PDSCH position candidate institute of J kind is determined, Then the corresponding time interval of the effective PDSCH position candidate institute of J kind is determined as PDSCH position candidate and PDCCH is waited The time interval that bit selecting is set.

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 2.Wherein, in table two 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 two for example has 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 two can be pre-defined , it can also be configured with the network equipment to terminal.

Table two

Wherein, table two 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 two (i.e. primary sign and Symbol lengths) it is as shown in figure 11 with the row format up and down in each time slot, if row format indicates preceding 10 in each time slot up and down A 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 sequence 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 Downstream format.Then by the K in serial number 0 and serial number 1₀Value is determined as running time-frequency resource and the PDCCH candidate of PDSCH position candidate The time interval of the running time-frequency resource of position.

In some embodiments, the first running time-frequency resource includes R sub- running time-frequency resources, between the time of the first information instruction It is divided into T kind, a kind of implementation of above-mentioned S601 or S801 may include:

When for every kind in the sub- running time-frequency resource of each of the R sub- running time-frequency resource and the T kind time interval Between be spaced, if H sub- running time-frequency resources are located at m in the R sub- running time-frequency 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 running time-frequency 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 includes 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 running time-frequency 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 two and Figure 11, it is known that the symbol 3- symbol 7 in time slot 0 is Sub- running time-frequency resource, the symbol 5- symbol 9 in time slot 0 are sub- running time-frequency resource, and the symbol 3- symbol 7 in time slot 1 is sub- running time-frequency resource, Symbol 5- symbol 9 in time slot 1 is sub- running time-frequency resource, and the symbol 3- symbol 7 in time slot 2 is sub- running time-frequency resource, the symbol in time slot 2 Number 5- symbol 9 is sub- running time-frequency resource, and therefore, the first running time-frequency resource includes 6 sub- running time-frequency resources.Wherein, the 1st sub- running time-frequency resource Including the symbol 3- symbol 7 in time slot 0 and it is located in time slot 0, since time interval is 0 time slot, when may thereby determine that Gap (0-0), i.e. time slot 0；2nd sub- running time-frequency resource includes the symbol 5- symbol 9 in time slot 0 and is located in time slot 0, due to the time Interval is 0 time slot, may thereby determine that time slot (0-0), i.e. time slot 0；3rd sub- running time-frequency resource includes the symbol in time slot 1 Number 3- symbol 7 and it 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； 4th sub- running time-frequency resource includes the symbol 5- symbol 9 in time slot 1 and is located in time slot 1, since time interval is 0 time slot, It may thereby determine that time slot (1-0), i.e. time slot 1；When 5th sub- running time-frequency resource includes the symbol 3- symbol 7 in time slot 2 and is located at In gap 2, since time interval is 0 time slot, time slot (2-0), i.e. time slot 2 may thereby determine that；6th sub- running time-frequency resource packet It includes the symbol 5- symbol 9 in time slot 2 and is located in time slot 2, since time interval is 0 time slot, may thereby determine that time slot (2-0), i.e. time slot 2.Thus, it is possible to obtain the second running time-frequency resource includes time slot 0- time slot 2.After determining the second running time-frequency resource, Terminal and/or the network equipment are in the corresponding time range of time slot 0- time slot 2, according to the second information at least one described downlink It determines that effective PDCCH monitors opportunity on BWP, such as shown in Figure 10, determines that there are when PDCCH monitoring in time slot 0 and time slot 2 Machine, since the PDCCH monitoring opportunity in time slot 0 does not weigh with third running time-frequency resource (including the running time-frequency resource for speeds match) It is folded, so it is that effective PDCCH monitors opportunity that the PDCCH in time slot 0, which monitors opportunity,；Since the PDCCH in time slot 2 monitors opportunity It is Chong Die with third running time-frequency resource (including the running time-frequency resource for speeds match), so PDCCH in time slot 2 monitors opportunity is not Effective PDCCH monitors opportunity, so when the effective PDCCH monitoring opportunity finally determined monitors for the PDCCH in time slot 0 Machine.

Optionally, after terminal and/or the network equipment execute above-mentioned S602 or S802, if in second running time-frequency resource (m_v-K_0,S) in the corresponding time range of time-domain resource unit, according to the second information at least one downlink BWP really It makes effective PDCCH and monitors opportunity, then terminal and/or the network equipment determine H sub- time-frequencies in the R sub- running time-frequency resources Resource is effective PDSCH position candidate.If in the time range of time slot 0 and time slot 2 in the second running time-frequency resource, according to Two information determine that effective PDCCH monitors opportunity at least one downlink BWP, then in the second running time-frequency resource when The corresponding 1st sub- running time-frequency resource of gap 0 and the 2nd sub- running time-frequency resource are effective PDSCH position candidate, and with the second time-frequency The corresponding 5th sub- running time-frequency resource of time slot 2 and the 6th sub- running time-frequency resource in resource are effective PDSCH position candidate.

Optionally, after terminal and/or the network equipment execute above-mentioned S602 or S802, if in second running time-frequency resource (m_v-K_0,S) in the corresponding time range of time-domain resource unit, according to the second information at least one downlink BWP not Determine that effective PDCCH monitors opportunity, then terminal and/or the network equipment determine the H period of the day from 11 p.m. to 1 a.m in the R sub- running time-frequency resources Frequency resource is not effective PDSCH position candidate.If in the time range of the time slot 1 in the second running time-frequency resource, according to second Information is not determined by effective PDCCH at least one downlink BWP and monitors opportunity, then in the second running time-frequency resource when The corresponding 3rd sub- running time-frequency resource of gap 1 and the 4th sub- running time-frequency resource are not effective PDSCH position candidates.

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 running time-frequency 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, as shown in Figure 10, the value collection that UE is configured for K1 is combined into { 1,2,3 }.In time slot 3 Upper feedback HARQ-ACK information.Shown in the table table two as above of the time-frequency resource allocating of UE configuration, it can be seen that in each time slot It is configured with 4 possible PDSCH position candidates.The corresponding K0 value of each possible PDSCH position candidate is (as in table two K₀) it is 0.Structure of time slot in each time slot is as shown in figure 11.

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, it is determined whether there is effective PDCCH to monitor opportunity, specifically, UE first can basis The prior art, by high level configuration PDCCH listening period, PDCCH monitor deviant, the parameters such as PDCCH listening mode, from when PDCCH is judged whether there is in gap 0, time slot 1 and time slot 2 monitors opportunity.As shown in Figure 10, UE discovery is in time slot 0 and time slot 2 It is interior, there is PDCCH to monitor opportunity, then UE can also be according to third running time-frequency resource (the i.e. rate-matching money of network equipments configuration Source) judge whether oneself can monitor PDCCH position candidate in above-mentioned time slot 0 and time slot 2.As shown in Figure 10, in time slot 2, It is overlapping that UE needs the PDCCH position candidate monitored to have with the rate-matching resource of network equipments configuration, and UE will not monitor this A little PDCCH position candidates.Therefore UE never receives PDCCH (down dispatch information) in time slot 2, is determining semi-static code This when, naturally also there is no need to take into account time slot 2.Therefore by screening, in three time slots of time slot 0~2, only There is the active position of 2 PDSCH in time slot 0, the active position of the two PDSCH is needed in the semi-static code book of subsequent determination It takes into account in the process.

Therefore, the present embodiment further can determine semi-static code book according to rate-matching resource, and it is negative to reduce code book It carries, enhancing communicates new energy.

In the second implementation, as shown in figure 12, the value collection that UE is configured K1 is combined into { 1,2,3 }.On time slot 5 Feed back HARQ-ACK information.The table of the time-frequency resource allocating of UE configuration is as shown in following table three, it can be seen that matches in each time slot 4 possible PDSCH position candidates are set.The corresponding K0 value of each possible PDSCH position candidate is not all 0.UE is in time slot 2, in any one time slot of time slot 3 and time slot 4, effective PDSCH transmission position, i.e. serial number 0 can be obtained according to the prior art With the corresponding position of serial number 1.It later can be in time slot 2, in any one time slot of time slot 3 and time slot 4, according to serial number 0 and serial number 1 Corresponding K0 value, it is determined whether there is effective PDCCH to monitor opportunity.

Table three

Serial number (Index)	K0	Primary sign and symbol lengths (SLIV)	Map type
				0	0	3,5 symbol lengths of symbol	A
1	2	5,5 symbol lengths of symbol	A
				2	0	7,5 symbol lengths of symbol	B
3	2	9,5 symbol lengths of symbol	B

UE can be according to the prior art, by the PDCCH listening period of high level configuration, and PDCCH monitors deviant, PDCCH prison The parameters such as mode are listened, PDCCH is judged whether there is from time slot 2, time slot 3 and time slot 4 and monitors opportunity.Specifically, for when Time-domain resource Allotment Serial Number 0, K0=0 in gap 4, therefore when UE can determine whether to have PDCCH monitoring in this time slot (time slot 4) Machine, discovery exist；For the time-domain resource Allotment Serial Number 1, K0=2 in time slot 4, therefore UE can determine whether (the time slot 4-K0=of time slot 2 Time slot 2) in whether have PDCCH monitor opportunity, discovery exist.Therefore up to the present, the serial number 0 in time slot 4 and serial number 1 are corresponding PDSCH position candidate be all effective.According to identical method, UE may determine that serial number 0 and serial number 1 in time slot 2 correspond to PDSCH position candidate be all effective；Serial number 0 and the corresponding PDSCH position candidate of serial number 1 in time slot 3 be all it is invalid, Because all monitoring opportunity without PDCCH in time slot 3 and time slot 1.

In the present embodiment, UE can also be according to the third running time-frequency resource (rate-matching resource) of network equipments configuration Judge whether oneself can monitor PDCCH position candidate in above-mentioned time slot 2 and time slot 4.As shown in figure 12, in time slot 4, UE is needed The PDCCH position candidate to be monitored has overlapping with the rate-matching resource that base station configures.Therefore the serial number 0 in time slot 4 is right The PDSCH position candidate answered is invalid.Similarly, in time slot 0, the PDCCH position candidate and base station that UE needs to monitor are configured Rate-matching resource have overlapping.Therefore the corresponding PDSCH position candidate of serial number 1 in time slot 2 is invalid.

Therefore by screening, in three time slots of time slot 2~4, only in the serial number 1 in time slot 2 and the sequence in time slot 4 Number 0 corresponding 2 PDSCH are effective.The active position of this 2 PDSCH needs the process in the semi-static code book of subsequent determination In take into account.
