It, may be within a very long time all since the generation of the data packet of URLLC business has sudden and randomness It not will produce data packet, it is also possible to generate multiple data packets within a very short time.The data packet of URLLC business is in most cases For parcel, such as 50 bytes.The characteristic of the data packet of URLLC business can influence the resource distribution mode of communication system.Here Resource include but not limited to：Time-domain symbol, frequency domain resource, running time-frequency resource, code source and Beam resources etc..Usual system The distribution of resource is completed by base station, is illustrated by taking base station as an example below.If base station use the mode of reserved resource for URLLC traffic assignments resources, then system resource is waste when no URLLC business.And the short time-delay of URLLC business Characteristic requirements data packet is transmitted within the extremely short time, so base station needs reserved sufficiently large bandwidth to give URLLC business, So as to cause resource utilization ratio degradation.
Since the data volume of eMBB business is bigger, and transmission rate is relatively high, therefore generally use longer time Scheduling unit carries out data transmission to improve efficiency of transmission, for example, using a time slot of 15kHz subcarrier spacings, it is 7 corresponding Time-domain symbol, corresponding time span are 0.5ms.The shorter time scheduling unit of URLLC business datum generally uses, to meet The demand of ultrashort time delay, for example, using 2 time-domain symbols of 15kHz subcarrier spacings, or use 60kHz subcarrier spacings A time slot, corresponding 7 time-domain symbols, corresponding time span is 0.125ms.
Due to URLLC business data it is sudden, in order to improve resource utilization ratio, base station usually will not be The downlink data transmission of URLLC business reserves resource.When URLLC business datums reach base station, if not idle at this time Running time-frequency resource, base station can not wait for meet the ultrashort delay requirement of URLLC business by the eMBB business datums of this scheduling URLLC business datums are scheduled again after being transmitted.The mode for seizing (preemption) may be used in base station, is URLLC business datums distribute resource.
Fig. 4 shows the schematic diagram of the application one embodiment.As shown in figure 4, seizing here refers to base station Distribution, be used for transmission selected section on the running time-frequency resource of eMBB business datums or the running time-frequency resource of whole is used for transmission URLLC Business datum, base station do not send the data of eMBB business on the running time-frequency resource for being used for transmission URLLC business datums.
Further, due to the emergency and importance of URLLC business, the network equipment may be for URLLC service selections most Suitable frequency domain resource is to ensure the reliability of URLLC business.In this case, by the eMBB user of URLLC service impacts (or by eMBB user of URLLC business preempting resources) may more than one.Different eMBB users are by URLLC service impacts It is also different for the percentage of the total resources of its distribution that resource accounts for the network equipment.In general, shared by impacted running time-frequency resource Percentage it is bigger, the reliability drop that the signal that the reliability of the eMBB that is affected transmission is sent relative to original plan can reach Low is more.
According to foregoing description as it can be seen that for by the eMBB business of URLLC service impacts, due to the downlink of the secondary eMBB business Data fail to implement to send in whole resources that base station is dispatched, and the transmission reliability of the secondary eMBB business can be due to underlying cause And reduce, this is because：
1. the terminal device for receiving eMBB business does not know that the running time-frequency resource for being already allocated to it is allocated to another again URLLC business is transmitted, and will not belong to the data of oneself when the data being Myself carry out subsequent demodulating and decoding.
2. further, it is assumed that eMBB user be known that in the running time-frequency resource for being already allocated to it which resource allocation to Another transmission, and the data carried on the deallocated resources are abandoned and (abandons and receives the non-number of oneself in signal According to).For example, 20% in the running time-frequency resource that eMBB user has closely distributed is reassigned to another transmission.In this case, Since the reduction of resource can be used in eMBB user, the protection in eMBB data transmission procedures becomes smaller accordingly, therefore this time EMBB data transmission credibilities decline.
Therefore, the embodiment of the present application is provided by sending control information to terminal device, indicates that the terminal device is not belonged to In the resource that the business of oneself is seized, it is one's own business that terminal device, which can distinguish the information carried in which resource, Data, the information carried in which resource is not one's own business datum, is received to one's name to improve terminal device Business datum reliability.
In the embodiment of the present application, terminal device empty signal can be specifically the time frequency signal emptied before demodulation.For example, Demodulation front signal discarding to be emptied no longer is handled (such as demodulation etc.), the confidence of corresponding bit by terminal device It is zero to spend (Soft Inform ation) equipment.Emptied alternatively, terminal device treats empty signal before decoding, i.e., will with wait for empty signal Confidence level (Soft Inform ation) zero setting of corresponding bit.Therefore, described empty can also refer to discarding, remove, zero setting etc., the present invention is not It is construed as limiting.
In other words, described empty can wait for that empty signal is not used in decoding.
Terminal device can also empty the corresponding signal of a running time-frequency resource, i.e., terminal device is without using a time-frequency money The signal of source carrying is into row decoding, and in other words, the signal of running time-frequency resource carrying is not used in decoding.
In the embodiment of the present application, supplement transmission (supplemental transmission) can also be known as additionally weighing Multiple (additional repetition) or supplement repeat (supplemental repetition), and the present invention does not limit It is fixed.
In the embodiment of the present application, in the embodiment of the present application, resource includes one or more frequency domain units on frequency domain, Frequency domain unit may include one or more resource blocks, can also include one or more resource block groups.Above-mentioned resource is in time domain Upper includes one or more time quantums, and time quantum may include one or more time-domain symbols, can also including one or Multiple time slots (slot) can also include one or more mini time slots (mini-slot), alternatively, including one or more sons Frame (subframe).When above-mentioned frequency domain unit includes multiple frequency domain units, multiple frequency domain unit can be continuous, and can also be Discontinuous, the application does not limit.When above-mentioned time quantum includes multiple time quantums, multiple time quantum can be connected It is continuous, it can also be discontinuous, the application does not limit.Wherein, above-mentioned time-domain symbol can be orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol can also be single carrier frequency division multiplexing (single-carrier frequency-division multiplexing, SC-FDM) symbol.It should be understood that the symbol can To include the corresponding cyclic prefix of the symbol.
It should be noted that although in the present invention by taking URLLC seizes eMBB transfer resources as an example, the present invention not as Limit.For example, the user of preempting resources can also be the eMBB user of high priority.The URLLC user of low priority may also be by The user of high priority seizes.Other type of user in network may also become the person of seizing or by the person of robbing.The money being preempted Source may either control information for transmission data or be left blank white (such as avoid interference other signals or hide interference). It is seized in another example application background of the present invention may not be resource, and sends signal and receive uneven strong jamming, the secondary biography Defeated a certain part resource receives strong jamming, and the network equipment is by indicating that the disturbed terminal device influenced of information instruction understands The signal received on running time-frequency resource where the interference.And optionally, where the network equipment will interfere on running time-frequency resource Former carrying signal (being equivalent to previously described residual signal) retransmits to terminal device.
The method that the embodiment of the present application is described below.Fig. 5 shows the interaction figure of the method for the application one embodiment.Such as Shown in Fig. 5, this method comprises the following steps.It should be noted that the dotted line in Fig. 5 indicates that corresponding step is optional step. In addition, each step in Fig. 5 can be executed according to the different sequences presented from Fig. 5 respectively, and it is possible to not Execute all operationss in Fig. 5.It should also be understood that in the embodiment of the present application, " first ", " second " and " third " is only to be used for Different objects is distinguished, for example, different information, different running time-frequency resources, different data etc. are distinguished, it should not be to the application structure At any restriction.
As shown in figure 5, this method includes：
Step 501, the network equipment sends the first instruction information to terminal device, and the first instruction information is used to indicate down First resource in row data channel, at least part of the first resource are used to send the first part in coded data.
Specifically, the first instruction information can be Physical layer control information, which can be carried on first In down control channel, wherein first down control channel can be Physical Downlink Control Channel (physical Downlink control channel, PDCCH) or other down channels for carrying Physical layer control information, the application It does not limit.
It should be understood that the first instruction information can be the information in the first control information, which is used for Dispatch the transmission of the coded data on first resource.
Optionally, as the application one embodiment, the coded data is the network equipment at least one encoding block (code block, CB) encodes obtained data.That is, when the network equipment needs to send at least one encoding block, it will At least one encoding block is encoded to obtain coded data.
Specifically, downstream data channel can be the Physical Downlink Shared Channel (Physical for carrying data Downlink Shared Channel, PDSCH) or other down physical channels for carrying data.
At least part of first resource is used to send the first part in coded data, that is to say, that the network equipment phase Hope or actually use first part of at least part resource of first resource into terminal device transmission coded data.
Lower mask body introduces how the first control information indicates first resource.
Specifically, which can indicate the position of first resource by explicit way, can also be by hidden Formula mode indicates the position of first resource.
Specifically, the frequency domain position of the first control information instruction terminal equipment first resource, terminal device being capable of basis The control information determines that the frequency domain position of first resource, terminal device can also be true according to predefined rule and the control information Determine the time-domain position of first resource.
For example, predefined rule can be the time-domain position of the first resource be this first control information where Time domain unit；In another example the time-domain position and frequency domain position of the first control direct instruction terminal equipment first resource of information, because This, terminal device can determine the position of first resource according to the first control information.
Step 502, the network equipment sends control information to the terminal device, and the control information includes the second finger Show that information, the signal sent on the Secondary resource that the second instruction information is used to indicate in the downstream data channel are not used in Decoding, the Secondary resource are a part for the first resource.
Specifically, control information can be Physical layer control information.The control information can be carried on the control of the second downlink In channel, wherein second down control channel can be Physical Downlink Control Channel (physical downlink Control channel, PDCCH) or it is other for carrying the down channel of Physical layer control information, and the application does not limit.
It should be understood that the control information in step 502 is different from the first control information in step 501, for the convenience of description, Control information that can be in step 502 is referred to as the second control information.
Optionally, as the application one embodiment, the second instruction information is used to indicate the downstream data channel The signal sent on interior Secondary resource is not used in decoding：The second instruction information is used to indicate the downlink data letter The signal sent on Secondary resource in road is not used in decoding at least one encoding block.
Specifically, if the terminal device in step 501 and step 502 is that the first business (such as eMBB business) is corresponding Terminal device, then the information that the network equipment is sent on Secondary resource may be that the second business (such as URLLC business) is corresponding Terminal device, it should be appreciated that the corresponding terminal device of the first business and the corresponding terminal device of the second business can be identical Terminal device, or different terminal devices, the application do not limit.
That is, the second business may rob a part of resource for accounting for first resource, i.e., the second money in step 502 Source, the network equipment have sent the data of the second business using Secondary resource, therefore, on the Secondary resource in the downlink data information The signal of transmission is not used in the decoding of the first business.
In step 502, when the second instruction information occupies A2 bits, the second control information further includes third Indicate that information, the third instruction information are used to indicate the information resources in the downstream data channel, the information resources are used Second part in the transmission coded data；When the second instruction information occupies A1 bits, the second control letter Breath does not include that the third indicates information；A2<A1, A1 and A2 are positive integer.
In step 502, information resources are used to send the second part in above-mentioned coded data, that is to say, that network is set It is standby it is expected there are no the remaining coded datas for issuing terminal device to be sent to terminal device in coded data.In another way It says, plans to send by the volume of the first control message scheduling to the terminal device of first business on first resource in the network equipment Code data, still, the Secondary resource due to carrying the signal is seized by the second business, only on the part resource of first resource The first part of the coded data of the scheduling is had sent, and fails to send the coded data remainder of the scheduling, coded data Remainder includes the second part mentioned in step 502.
Optionally, which can also indicate Modulation and Coding Scheme used in coded data to terminal device (Modulation and Coding Scheme, MCS), transmission mode etc..The transmission mode may include transmission coded number According to the pre-coding matrix used in the used number of plies, transmission coded data, lobe etc. used in transmission coded data.It should First control information can use the mode of explicit (explicit) to indicate MCS, transmission mode etc., for example, in the first control letter Breath includes that corresponding field indicates corresponding information.First control information can also be referred to by the way of implicit (implicit) Show configured transmission, for example, by the format of the first control information, the application does not limit.Specifically, described first control is believed The index for ceasing the MCS candidate schemes transmitted to the terminal device instruction network equipment for dispatch terminal equipment, is hereinafter referred to as dispatched The MCS indexes used.Optionally, information resources are used to send the second part in above-mentioned coded data, can also be that network is set Standby it is expected more coded datas issuing terminal device, terminal caused by alleviate due to having lacked a part of coded data is set The case where standby decoding reliability decrease.
That is, in one case, the second instruction information occupies A2 bits, although the terminal for receiving the first business is set It is standby to will not belong to the signal of oneself according to the second of the network equipment the control information determination and remove from receiving in signal, due to can The running time-frequency resource used reduces (code rate for being equivalent to the secondary transmission rises), and the reliability of the transmission being affected still can It reduces.If further, more coded datas are sent to the corresponding terminal device of the first business by the network equipment, this The corresponding terminal device of one business utilizes the second part of the first part and subsequently received coded data in coded data Demodulating and decoding is carried out, therefore the reliability of the transmission of the first business can be promoted.
In this case, when the first resource percentage shared by the impacted Secondary resource is bigger, even if terminal Equipment can indicate that information empties the signal being carried on Secondary resource according to above-mentioned second, and terminal device still needs additional Supplement transmission could be transmitted according to the correct demodulating and decoding original of original transmission supplemented after transmitting and emptying corresponding signal and supplement transmission The data carried jointly.In this case, it indicates that the main function of information is to aid in terminal device and empties corresponding signal to avoid Soft memory for decoding pollutes.Therefore, if after the network equipment confirms follow-up scheduling supplement transmission, can only with compared with Few bit corresponds to above-mentioned instruction information, plays to avoid error signal being introduced into soft memory and causes decoding error, leads to simultaneously The third instruction information instruction crossed in the second control information transmits relevant information with supplement.
It should be understood that the former transmission mentioned in the embodiment of the present application refers to the volume of the first control message scheduling in step 501 Code data.
In other situations, the second instruction information occupies A1 bits, and the second control information does not refer to including third at this time Show information, that is to say, that the network equipment will not be sent to the second part of coded data by the second control information instruction First business corresponding terminal device, this when, the second instruction information need more accurately to send on instruction Secondary resource Signal is not used in decoding, also, A1>A2, since the second instruction information occupies more bit numbers, when impacted Secondary resource When the percentage of shared first resource is smaller, even if not supplementing the second part of transmission coded data, terminal device root According to above-mentioned pointing accuracy it is higher second instruction information empty the signal carried on Secondary resource after, terminal device remain to The correct demodulating and decoding coded data of high probability, the second instruction information can indicate the second impacted money with higher precision Source is conducive to improve terminal device according to the first part of the coded data sent on first resource, the demodulating and decoding coded number According to correct probability.
Optionally, bit number N, the bit number A1 that the second instruction information uses which uses, or One or more of the bit number A2 that second instruction information uses can be as defined in communication standard.Alternatively, the bit Number N, bit number A1, one or more of bit number A2 can be that the network equipment is configured by high-level signaling, Such as radio resource control signaling (Radio Resource Control, RRC), N is positive integer.
Optionally, when A1 bits correspond to the second instruction information in the second control information, the second control information Format (either type) be the first format (or type), it is described second control information in A2 bits correspond to instruction information when It waits, the format (either type) of the second control information is the second format (or type), it should be appreciated that the first format and the second lattice Formula can be identical.Alternatively, the first format can be different from the second format.First format benefit identical with the second format is to save Standardized complexity.The first format benefit different from the second format is conducive to clearer logic convenient for design Product, and help to reduce time of product development.Further, if the first format and the second format are different, above-mentioned second It includes a field to control in information, and the format which is used to indicate the second control information is the first format or the second lattice Formula.
Further, the bit number shared by the second control information is N, and no matter whether the second control information includes that third indicates The bit number of information, the second control information itself does not change, and helps to reduce terminal device blind Detecting the second control information When complexity.Meanwhile using different occupation modes according to the impacted situation of Secondary resource, second control can be utilized Information processed flexibly and effectively improves the reliability that the corresponding terminal device of the first business receives coded data.
Optionally, bit number N, at least one of bit number A1 and bit number A2 can be communications standard specifications It is defined, can also be that the network equipment is configured by high-level signaling.
Lower mask body introduces how the second instruction information in the second control information indicates the signal carried on Secondary resource The corresponding terminal device of the first business is not used in into row decoding.
In the case of one kind, when the second control information includes that third indicates information, third indicates that information indicates information resources When second part for sending coded data (that is indicate that information informs the terminal device of the first business by third, When by having the supplement transmission for coded data), what the A2 bits that the second instruction information includes indicated is the tool of Secondary resource Body position.Specifically, which is divided into A2 parts, and each bit corresponds to 1 part, pointing accuracy 1/ A2, such as A2 are 8 either 7 or 14.
When the second control information includes failing in exam three instruction information, that is to say, that the network equipment will not be sent for coding When the supplement transmission of data, second indicates the A1 bits instruction that information includes and Secondary resource specific location.Specifically, The second control information instruction first resource is divided into A1 parts, and each bit corresponds to 1 part, pointing accuracy 1/A1, such as A1 is 36 Either 32 or 24.
In another case, when the second control information includes that third indicates information, third indicates information instruction third money (that is indicate that information informs that the terminal of the first business is set by third when source is used to send the second part of coded data It is standby, it will when having the supplement transmission for coded data), it is which CB or which encoding block that the content of instruction, which is impacted, Group (code block group, CBG).In this case, the Secondary resource be with should which or which CB, or Person, which or which corresponding resources of CBG.In other words, the Secondary resource is indicated according to the first control information With should which either which CB alternatively, which or which corresponding resources of CBG.
Optionally, bit number A2 is consistent with the maximum CBG numbers of system configuration, and a CBG is represented per bit.Or bit Number A2 is variable, and CB numbers corresponding with the coded data in step 501 are consistent.Terminal device according to the instructions of A2 bits, By the corresponding signal removals of corresponding CB or CBG.
Optionally, bit number A2 is equal to 1, i.e. the network equipment only indicates whether be affected in former transmission by 1 bit.If Terminal device confirms that original transmission is affected, by the corresponding all reception signal removals of original transmission.In other words, if terminal device is true Recognize former transmission to be affected, all data-signals received on first resource are removed.
When the second control information includes failing in exam three instruction information, that is to say, that the network equipment will not have for coded number According to supplement transmission when, second instruction information include A1 bits instruction be also Secondary resource specific location.Specifically, should Second control information instruction first resource is divided into A1 part, and each bit corresponds to 1 part, pointing accuracy 1/A1, for example, A1 for 36 or Person 32 or 24.
Further, in this case, the second control information can also include the 5th instruction information, the 5th instruction What information was used to indicate the instruction of the second instruction information is the location information of specific Secondary resource, or instruction is Secondary resource pair The CB or CBG answered.
Further, in this case, when second instruction information instruction be the specific location of Secondary resource when, Second control information can also include the 6th instruction information, and the 6th instruction information is used to indicate the second instruction information instruction second When resource, the instruction granularity of A1 bits or A2 bits in time domain and frequency domain.For example, A1 bits are 36 bits, the 6th instruction After information can indicate that 1 bit in 36 bit represents and is divided into first resource in the time domain and is divided into 9 parts on 4 parts of frequency domains A copy of it or the 6th instruction information can indicate that 1 bit of 36 bit represents and first resource is divided into 6 in the time domain It is divided into a copy of it after 6 parts on part frequency domain.In another example A1 bits are 24 bits, the 6th instruction information can indicate 24 ratio 1 bit in spy, which represents to be divided into first resource in the time domain on 4 parts of frequency domains, is divided into a copy of it or the 6th after 6 parts After instruction information can indicate that 1 bit of 24 bit represents and is divided into first resource in the time domain and is divided into 4 parts on 6 parts of frequency domains A copy of it.
The second control information is described below and how to indicate whether the corresponding terminal device of the first business has supplement transmission, It is just whether to send the second part of coded data on information resources, for simplicity, we are simple to be described as second Whether control information, which indicates to mend, passes.
Optionally, as the application one embodiment, the second control information further includes the 4th instruction information, wherein The 4th instruction information is used to indicate whether the second control information includes third instruction information and/or described the Four instruction information are used to indicate the second instruction information and occupy A1 bits or A2 bits.
Specifically, in the case of a kind of, the second control information includes the 4th instruction information, and the 4th instruction information can adopt It indicates to exist with explicit mode to mend and passes or passed without mending.For example, the 4th instruction information can be 1 bit field, also may be used With can also be by including 2 bits or 2 bits by the wherein two state instruction comprising fields more than 2 bits either 2 bits 1 bit instruction in above field.
Another situation, above-mentioned second control information can also use implicit method instruction to there is benefit and pass or do not have It mends and passes.For example, controlling whether the time-frequency resource indication that information uses has benefit to pass by predefined second.In another example instruction institute It states the second instruction information and occupies A1 bits or A2 bits, also can indirectly instruction terminal equipment be passed with the presence or absence of benefit.
How instruction terminal equipment determines that the second control information is corresponding to the first control information for lower mask body introduction.Due to step After the first part of coded data transmitted on the first resource of the first instruction message scheduling in rapid 501, the in step 502 The Secondary resource of the second instruction information instruction in two control information is a part for first resource, and step is carried on the Secondary resource The second part of coded data in rapid 501.Therefore, it is necessary to instruction terminal device step 502 the second control information and step Coded data in 501 is corresponding, and what is carried on information resources in step 502 is the second part of the coded data in step 501.
In a kind of mode, terminal device is according to the position of the second control information in the time domain with first resource in time domain On position between relationship determine.For example, time quantum and time quantum shared by first resource where the second control information It is identical.Or time quantum where the second control information is adjacent with the time quantum shared by first resource, is provided in the first time domain Back to back time quantum after source, it should be appreciated that terminal device can also determine step 502 according to other position relationships In second control information it is corresponding to the coded data in step 501.
