Re-transmission rule schematic diagram based on modulation coding scheme as shown in Figure 4, in the figure, it is assumed that 1ms corresponds to 8 Slot, each slot are the transmission units of minimum, and the time domain length for exempting from authorized transmissions resource is 8 slot, under this arrangement, then Period is 1ms, the basic granularity for exempting from the frequency domain of authorized transmissions resource be one or more resource blocks (Resource Block, RB).Wherein, Fig. 4 a are the re-transmission schematic diagram of exemplary MCS configurations, that is, retransmit and first pass uses identical MCS；Fig. 4 b are The re-transmission schematic diagram of exemplary another MCS configuration, as retransmit relative to the MCS just passed increase with the number continuously retransmitted and Gradually variation setting multiple, specifically, for example, transmitting the valid data of 20bit using 1/3 code check, then total data is 60bit has 2/3 redundancy, if code check is incremented by, i.e., double, then code check becomes 1/6, total data 120bit, this 120bit performances then need twice of time to transmit in the time domain, show and then need twice of carrier wave on frequency domain to transmit, It then shows in the time domain in fig. 4b, transmission unit is double, i.e., it is 1 slot just to pass, and retransmits then need n-th+2 and for the first time Two slot of n+3, second of re-transmission then need n-th+4 to n-th+7 four slot；Fig. 4 c are another exemplary MCS configurations Retransmit schematic diagram, as every time it is continuous retransmit the MCS that uses relative to first time retransmit with the number continuously retransmitted increase and by Secondary variation sets multiple, and difference lies in the variation of MCS is not based on just biography to Fig. 4 c and Fig. 4 b in Fig. 4 c, and is based on weight for the first time It passes, i.e., retransmits for the first time and need n-th+2 slot, retransmit need n-th+3 and n-th+4 two slot for the second time, and so on. The first time transmission that rule variation is based on it can be seen from Fig. 4 b and Fig. 4 c can just be passed, and can also be to retransmit for the first time. In addition, rule change can also be every time the continuous transmission for retransmitting the configured transmission used and being used relative to first time transmission Parameters variation sets multiple (not shown).It should be noted that in Fig. 4, relating to repeat to transmit, it is a kind of letter to repeat transmission Single repetition, using with just pass identical parameter and transmit, behind repetition transmission is described in detail further.Certainly, the re-transmission based on MCS Rule can also include other rules, such as：The continuous MCS used that retransmits is relative to the first MCS increase settings for passing and using every time Multiple does not describe one by one in conjunction with attached drawing herein.

Re-transmission rule schematic diagram based on time-domain resource selection mode as shown in Figure 5, time-domain resource selection mode are main The parameters such as size are bound including time slot.Fig. 5 a are the exemplary one re-transmission rule configuration signal based on time-domain resource selection mode Figure, in fig 5 a, the timeslot number (i.e. time slot binds size) for just passing and retransmitting is identical, i.e., the timeslot number just passed is a slot, Then the subsequent timeslot number retransmitted every time is all a slot；Fig. 5 b be it is exemplary another based on time-domain resource selection mode Retransmit regular configuration schematic diagram, in figure 5b, every time the continuous timeslot number for retransmitting binding relative to the first timeslot number for passing binding with The number continuously retransmitted increases and gradually changes setting multiple, i.e., the time slot just passed is n-th of slot, the time slot retransmitted for the first time For n-th+2 and n-th+3 two slot, second of time slot retransmitted is n-th+4 to n-th+7 four slot, is 22 powers, if Also third time retransmits, then the timeslot number that third time retransmits is eight slot, and so on；Fig. 5 c are that exemplary another is based on The re-transmission rule configuration schematic diagram of time-domain resource selection mode, in fig. 5 c, every time the continuous timeslot number for retransmitting binding relative to Just pass binding timeslot number variation setting multiple, herein be increase be twice, i.e., for the first time retransmit time slot be n-th+2 and n-th+ 3 two slot, second of time slot retransmitted is n-th+4 to n-th+5 two slot, and the time slot that third time retransmits is n-th+6 and n-th + 7 two slot.In Fig. 5 b and Fig. 5 c, it is relative to just pass the timeslot number variation of binding, in fact, can also be opposite The timeslot number that binding is retransmitted in first time is changed.

The schematic diagram of re-transmission rule as shown in FIG. 6 based on frequency domain resource selection mode, frequency domain resource selection mode master Will including frequency domain bandwidth etc. parameters.Fig. 6 a are the exemplary one re-transmission rule configuration signal based on frequency domain resource selection mode Figure retransmits identical with the first frequency domain resource number for passing binding in Fig. 6 a；Fig. 6 b are that exemplary another is selected based on frequency domain resource The re-transmission rule configuration schematic diagram of mode, in figure 6b, the continuous frequency domain resource number for retransmitting binding is relative to the first progress of disease every time Multiple is set, is to increase to be twice herein, i.e., the frequency domain resource number for for example just passing binding is 1 RB, then retransmits binding every time Frequency domain resource number is 2 RB.Certainly, the re-transmission rule based on frequent resource selection mode can also be other rule changes, example Such as：Every time the continuous frequency domain resource number for retransmitting binding relative to first time retransmit binding frequency domain resource number variation setting multiple, The continuous frequency domain resource number for retransmitting binding is retransmitted relative to the first frequency domain resource number for passing or retransmitting binding for the first time with continuous every time Number increase and gradually change setting multiple etc..

Optionally, before step S101, can also include：The rule continuously transmitted described in network equipment generation.

S102, the terminal device are according to the configured transmission to the network equipment continuous data transfer.

Configured transmission is set to network used by terminal device is retransmitted according to each time that includes in the re-transmission rule received It is standby to carry out continuous business transmission.Specifically, terminal device determines configured transmission according to the rule that the network equipment is sent, so as to It is enough that corresponding transfer resource is determined according to the determining configured transmission transmitted every time.For example, configured transmission includes being retransmitted Time-domain resource selection mode, if it is determined that re-transmission rule increase relative to first pass for the continuous frequency domain resource number for retransmitting binding every time It is twice, then exempts from the frequency domain resource of the binding in authorization resources occupied by the terminal device.

S103, the network equipment demodulate the data that the terminal device continuously transmits according to the rule.

Since rule is network equipments configuration, to which terminal device carries out the continuous of data on the transfer resource of selection Transmission, the network equipment can demodulate the data of terminal device transmission according to rule.

A kind of data transmission method provided according to embodiments of the present invention is sent to terminal device by the network equipment and carries out The rule continuously transmitted, the configured transmission that terminal device is configured according to the rule carries out uplink and continuously transmits, to realize net Network equipment can be configured flexibly the configured transmission that terminal device is continuously transmitted.

Further, it in the case of it is that multiple terminal devices are shared to exempt from authorized transmissions resource, continuously transmits will increase and touch Hit probability.Therefore, as a kind of realization method, the uplink in above-described embodiment exempts from authorized transmissions and continuously transmits the rule of business also May include just passing rule, the rule that just passes includes：The configuration and the punching of the length of the conflict avoidance window of transfer resource The prominent selection rule for avoiding transfer resource in window；The selection rule includes：It is randomly choosed in the conflict avoidance window One transfer resource just pass and is taken to the length of the conflict avoidance window according to the mark of the terminal device The transfer resource that modular arithmetic is just passed.The first biography rule can also be associated with and match with the regular separate configurations of re-transmission above-mentioned It sets.

Specifically, the network equipment just passes rule for terminal equipment configuration, including：The length of the conflict avoidance window of transfer resource The selection rule of transfer resource in the configuration of degree and the conflict avoidance window when terminal device has data arrival, is passed according to first Rule is chosen transfer resource and is sent and just passes.The first configured transmission for passing rule can be based on time-domain resource selection mode, also The selection of frequency domain resource can be expanded to, it can also time-frequency combination selection.

It is described by taking the selection of time-domain resource as an example.In given first biography running time-frequency resource, the first biography of transfer resource is selected Selecting rule includes：

Rule 1 randomly chooses an available resources in given conflict avoidance length of window L；

Rule 2, transfer resource is chosen according to the mark (UE ID) of terminal device or the number of system configuration.For example, Slot numbers=UE ID mod length of window L, wherein mod is modulo operation.So in the case of L=4：UE ID are 1, User can send in GF resource pools on first slot；UE ID are 7, user can in GF resource pools third It is sent on slot.As shown in Fig. 7 no using the first biography contrast schematic diagram for just passing rule, in figure 7 a, UE1 and UE7 First biography do not use and just pass rule, then be likely to result in the collision just passed, and in fig.7b, rule, UE1 passed as a result of first In biography at the beginning of n-th of slot, UE7 is then according to the above-mentioned rule 2 that just passes in biography at the beginning of the n-th+2 slot, and herein, conflict avoidance window is long L=4 is spent, the probability for generating and colliding just is passed in this way and greatly reduces, it should be noted that repeat to be to directly transmit here, not adopt It is controlled with recurring rule.

Therefore, using the data transmission method of this realization method, by limiting the behavior just passed, touching of just passing can be reduced Hit probability.

Although can be seen that the collision just passed from Fig. 7 b to be discretized, repeats transmission and still have conflict.Therefore, In another realization method, need to configure to repeating transport behavior, so that further discretization repeats the conflict of transmission. Therefore, uplink exempts from authorized transmissions to continuously transmit the rule of business include recurring rule, and the recurring rule includes repeating Time domain interval between transmission and just biography should meet more than or equal to default time domain interval.Whether Fig. 8 is using recurring rule Transmission schematic diagram is repeated, in Fig. 8 a, and then just biography conflict avoidance window carries out for the repetition transmission just passed, that is, repeats directly to send out It send, the probability of the repetition transmission generation collision of UE1 and UE7 is larger；And in figure 8b, it is assumed that just pass and repeat the default of transmission with it Time domain interval is set as 3 slot, and UE1 repeats to be sent in n+3 transmissions, but falls in conflict avoidance window, so to be moved to n + 4 are sent, and UE7 has carried out first transmission in n+2, then carry out repeating transmission in n+2+3, that is, n+5, reduce repetition in this way The collision probability of transmission.

Therefore, using the data transmission method of this realization method, the behavior of transmission is repeated by limiting, can reduce repetition The collision probability of transmission.

It, can also arbitrary two it should be noted that above retransmit rule, just pass rule and recurring rule and can be separately configured It is a or three configure simultaneously.

More re-transmission rules and just biography rule, recurring rule and jointly controlling for re-transmission rule will combine sender Formula is described in detail in following realization method：

In another realization method, the network equipment sends rule that terminal device continuously transmits to the terminal device, It can be sent by following several message：

1) above-mentioned rule is carried out for different business features by system message (System Information, SI) Configuration, SI are sent to multiple terminal devices by broadcast message；Can also be the specific rule of broadcast message configuration, then by with Instruction of the family specific messages into line discipline；

2) by wireless heterogeneous networks (Radio Resource Control, RRC) signaling to specific terminal device into The configuration of the above-mentioned rule of row；

It 3) can also be in media access control (Media Access Control, MAC) control element (Control Element, CE) in carry above-mentioned rule；

4) above-mentioned rule or inside Downlink Control Information (Downlink Control Information, DCI) is carried.

The main distinction of above-mentioned a variety of sending methods has at following 3 points：

1) flexibility of the above signal deployment is stepped up from front to back：SI<RRC signaling<MAC CE<DCI；

2) according to system design criteria, the information content that each level carries gradually reduces：SI>RRC>MAC CE>DCI；

3) SI is sent using broadcast mode, and a information can be used for all terminal devices in cell, opposite RRC, MAC CE etc. is directed to the sending method of particular terminal device, has smaller overhead.

Configuration regular in above-mentioned transmission message is described in detail separately below.Specifically to retransmit being configured to for rule Example, the configuration of other rules can refer to the configuration for retransmitting rule.In addition, though the embodiment of front has been provided for a variety of re-transmission rule Then, as different MCS is configured, when different/configuration of frequency domain resource selection mode, although regular different, configuration process one It causes.Therefore, subsequent embodiment mainly is unfolded to describe for configuring for the MCS rules of URLLC business.

In the following description, multiple realization methods that SI configurations retransmit rule are provided.

It is configured in SI in each realization method for retransmitting rule, it is necessary first to which agreement pre-defines MCS tables and configures In the network equipment and terminal device, or sent for continuously transmitting or the MCS tables of URLLC business, such as 1 institute of table in SI message Show.This table can be that LTE is existing, can also be the MCS tables newly defined for URLLC business.

In one implementation, described to retransmit the configuration that rule includes the configured transmission retransmitted at least once.The configuration It can be the mark for configuring the configured transmission that each time retransmits, such as MCS index, the MCS tables are prestored in terminal device, according to The mark of the configured transmission of each re-transmission of configuration, it may be determined that the specific transmission parameter values of each re-transmission.Specifically, example Such as, SI is continuously transmitted according to the uplink that above-mentioned MCS tables are URLLC business and is configured, and configuration repeatedly retransmits the mark of the MCS used Know.URLLC business that can be all uses the configuration.The network equipment and terminal device prestore above-mentioned MCS tables, then net The MCS marks (for example, MCS index) that URLLC business retransmit use by network equipment are sent to terminal device, terminal device By inquiring the MCS tables, it may be determined that MCS used by retransmitting.

The MCS tables that table 1 defines

MCS index	Modulation system	Code check
			0	QPSK	0.6
1	QPSK	0.3
			2	QPSK	0.15
3	BPSK	0.6
			4	BPSK	0.3
5	BPSK	0.15

Therefore, a kind of cell (information element) need to be defined, as follows：

In the cell, the meaning of essential element is as shown in table 2 below：

The cell element that table 2 configures re-transmission rule according to MCS tables describes example

It is described to retransmit the variation rule that rule includes the configured transmission for retransmitting use at least once in another realization method Then, wherein the rule change is the rule of the variation of the configured transmission based on first time transmission, and the first time transmission includes It just passes and retransmits for the first time.Specifically, the rule change includes following at least one rule：It is continuous every time to retransmit using identical The configured transmission, the continuous transmission ginseng for retransmitting the configured transmission used and being used relative to first time transmission every time Number with the number that continuously retransmits increase and gradually change setting multiple and every time it is continuous retransmit the configured transmission that uses relative to The configured transmission variation setting multiple that the first time transmission uses.For example, the first MCS passed of configuration and follow-up rule change, than Such as say that code check halves (0.6, which becomes 0.3, becomes 0.15) or modulation system depression of order (QPSK becomes BPSK).

Specifically, first, increasing MCS rule change lists newly, need to be set in the network equipment and terminal with protocol conventions and configuration In standby, or the rule is sent in advance by terminal device by signaling such as SI information and is stored, as shown in table 3：

3 exemplary MCS list of rules of table

It should be noted that the network equipment and terminal device acquiescence have stored MCS tables shown in table 1, which can By protocol conventions, to be stored directly in the network equipment and terminal device, can also be given by signal deployment by the network equipment Terminal device.

Then, for certain uplink, just biography or the MCS retransmitted for the first time and subsequent MCS rule changes are sent.

New cell need to be defined, a realization method is different from, need to include only to rule change in this realization method It indicates and does not have to a string of specific MCS of configuration：

In the cell, the meaning of essential element is as shown in table 4 below：

The cell element that table 4 retransmits rule according to the MCS and the configuration of follow-up rule change of first time transmission describes example

It should be noted that the first time transmission in table 4 can just be passed, can also be to retransmit for the first time.

If initial transmission refers to retransmitting for the first time, cell is readily modified as：

In the cell, the meaning of essential element is as shown in table 5 below：

The cell element that table 5 retransmits rule according to MCS and subsequent transmission the rule configuration retransmitted for the first time describes

In another realization method, the re-transmission rule includes the business feature of the data and retransmits at least once The configuration of the correspondence of the configuration of configured transmission and the configured transmission retransmitted at least once.URLLC is distinguished in the configuration Business feature.The business feature includes：The data package size of URLLC business, the time delay of data, QoS (Quality of Service) or QoE is identified etc..It carries out retransmitting being configured to for rule with the data package size that business feature is URLLC business below Example is described.

It includes two parts to configure content：The MCS lists continuously retransmitted are first defined, including the MCS configurations retransmitted at least once, The configuration can be MCS index, can also be specific MCS value, for configuration MCS index the case where, the network equipment and Terminal device, which can be given tacit consent to, has stored MCS tables shown in table 1；Then multiple business features (various data package sizes) are configured With the incidence relation of MCS lists.

It is corresponding, when terminal device initiates data transmission, configured transmission is selected according to business feature.Therefore, step S102 It specifically includes：The terminal device determines the biography of re-transmission corresponding with the service feature of the data according to the correspondence Defeated parameter.In addition, the network equipment also needs to know the business feature of terminal device, it just can determine that terminal device using which kind of Configured transmission is transmitted, to could correctly solve adjusting data.Therefore, the business feature of network equipment acquisition terminal device includes Following two modes：1) business feature when terminal device data transmission can be network equipments configuration to terminal device, institute Business feature need not be reported with terminal device, is that network device in advance is consulted with terminal device, corresponding work side Formula：The network equipment sends multigroup business feature to terminal device, and the network equipment is first specified when providing service to terminal device and used Which kind of business feature；2) terminal device can be according to the service selection rule of actual transmissions, and reports, corresponding working method： The network equipment sends multigroup business feature to terminal device, and terminal device reports the business feature of itself before data is transmitted.

The cell that need to be defined is as follows：

In the cell, the meaning of essential element is as shown in table 6 below.

The cell element that table 6 configures re-transmission rule according to business feature describes example

It is described for configuring MCS rules to SI above, SI configuration TTI bundling size is briefly described below Realization method：

First, cell new in SI is defined：

The cell element that table 7 binds size configuration re-transmission rule according to time slot describes example

Then, it increases list of rules newly, protocol conventions need to be used, as shown in table 8：

Table 8 binds the re-transmission list of rules of size about time slot

Number	Description
		0	Re-transmission doubles window, and remains unchanged
1	Window successive doubling

As can be seen that SI configuration time-domain resource selection modes are similar with configuration MCS rules, meanwhile, SI configures frequency domain resource Selection mode is also similar.

By way of configuring RRC signaling and retransmitting rule, the mode of RRC configurations is similar with the mode of SI, and difference exists It is sent with system information in one, one is carried by RRC signaling, and system information is destined to multiple terminal devices, is wide It broadcasts and send, and RRC signaling sends for specific terminal device.The cell of definition can be in RRC message- It is carried in RRCConnectionSetup.RRC signaling configuration, which retransmits rule, can refer to SI described above configuration re-transmission rules Each realization method.

By way of retransmitting rule MAC CE configurations, configuration mode also configures with SI, RRC above-mentioned and retransmits rule Mode then is similar, and configuration content includes two aspects：Agreement predefines MCS lists, as shown in table 1；It needs single data weight The MCS information configurations needed for sending are passed to terminal device.

Configuration process can equally distinguish display and implicit mode.The method of display has arranged all data and has all used phase Same configuration such as MCS is transmitted；The independence that implicit mode is supplied to terminal device certain, to adapt to different business It is required that.

This realization method only describes the mode of display configuration.What implicit mode need to only be defined in configuration in display mode Increase the element of instruction business feature in MACCE newly.

MAC layer issues control signaling by MAC CE, and a MAC CE format need to be newly defined to carry above- mentioned information,

And define corresponding MAC subheaders (sub-header).MAC CE for configuring re-transmission MCS patterns are defined as follows：

In the MAC CE of the new definition, the meaning of each essential element is as shown in table 9 below：

The configuration of table 9 retransmits the essential element description of the MAC CE of MCS patterns

Wherein Oct indicates that MAC CE press byte-aligned.

The corresponding defined MAC subheaders formats of MAC sub-header reusables LTE, R/F2/E/ as follows LCIDMAC sub-header：

Wherein, LCID:Refer to Logic Channel Identifier (Logical Channel ID)；R refers to reserved bit；F2 is used to indicate MAC subheader Length field sizes；E：Indication field is extended, is used to indicate behind the MAC subheaders and whether also has MAC subheaders.

The corresponding LCID of new definition MAC CE are needed simultaneously.LCID can use the reserved field of TS 36321-e00, can The MAC control elements newly defined are associated with to select 10111, updated table is as shown in the following table 10.

10 Values of LCID for DL-SCH of table

The realization method for being configured by PDCCH and retransmitting rule is described below：

The content that need to be configured is similar to the above embodiments, but PDCCH, other than being separately configured, acceptable and high-level signaling is such as RRC signaling is completed to configure jointly, to reduce the signaling overheads of DCI.It should be noted that the instruction of DCI can also be half quiet The scheduling of state can only be sent primary after configuration generates.

About the format of signaling, there are following methods：

Mode 1：Directly extend the realization method of DCI 0

It directly extends existing DCI 0 and carries each configuration for retransmitting used MCS.Such as 1 exemplary URLLCMSC of table It is found that the MCS retransmitted every time needs 3bit, therefore for example carries out 5 re-transmissions, then 15bit is needed to define 5 re-transmissions from front to back The MCS used.

Mode 2：It increases a DCI format newly, is used for URLLC uplink

A DCI format can also newly be defined and carry each configuration for retransmitting used MCS.

In mode 1 and mode 2, the re-transmission rule for describing DCI0 and the carrying of newly-increased DCI format includes at least once The configuration of the configured transmission of re-transmission, in fact, DCI0 and newly-increased DCI format, which can also carry other, retransmits rule, it is described heavy Pass the rule change that rule includes the configured transmission for retransmitting use at least once, wherein the rule change is based on for the first time The rule of the variation of the configured transmission of transmission, the first time transmission include just passing and retransmitting for the first time；Or the re-transmission rule The correspondence of business feature including the data and the configuration of the configured transmission retransmitted at least once and it is described extremely The configuration of few configured transmission once retransmitted.

As can be seen that mode 1 and mode 2 are all to send rule by DCI, the type of the DCI only used is not Together, regular realization process class is retransmitted with previously described carried by system information broadcast message, RRC signaling and MAC CE Seemingly, details are not described herein.

Mode 3：More sets are provided by message such as SI broadcast messages, RRC signaling, MAC CE and retransmit rule, wherein the rule Include then the configuration of the configured transmission of multigroup re-transmission, every group of configuration includes the configuration or at least of the configured transmission retransmitted at least once The primary rule change for retransmitting the configured transmission used, wherein the rule change is based on the first biography passed or retransmit for the first time The rule of the variation of defeated parameter；Meanwhile instruction is carried by extending DCI format 0 or newly-increased DCI x, the DCI is used for Indicate the configured transmission that the one of which of the configuration of the configured transmission for multigroup re-transmission that the terminal device uses retransmits Configuration, terminal device choose corresponding one of which according to the instruction of DCI and retransmit rule.For example, the new field in DCI 0, 000 indicates that the 1st of the high-rise configuration of selection retransmits rule, and 001 indicates that the 2nd of the high-rise configuration of selection retransmits rule, with such It pushes away.The expense of DCI can be saved in this way.

Mode 4：MCS list of rules is predefined in DCI x, and rule used by retransmitting then are indicated each time by DCI x Then.

In addition, being different from SI broadcast messages and RRC signaling configuration re-transmission rule, it is directly configured with the running time-frequency resource of transmission, Once there is data arrival, user can directly initiate to transmit；For the mode of PDCCH configurations, if determining according to existing LTE SPS The initial position of right way of conduct formula, uplink is influenced by PDCCH, may be had an impact to exempting from authorized transmissions.

Therefore, transmission initial position is contemplated that two ways, Fig. 9 are the signal being transmitted by PDCCH transmission rules Figure：

When the initial position that the active mode determination data according to LTE SPS as illustrated in fig. 9 is sent, as Fig. 9 a show Example by a kind of schematic diagram that PDCCH transmission rules are transmitted, i.e., in a cycle (n-th to n+7 slot, period For 8 slot) (n+1)th slot network equipment issue the configuration parameter of PDCCH, then the transmission of data can only be at (n+1)th Slot starts to transmit.In this fashion, terminal device starts to continuously transmit the number in the initial position of the DCI received According to.

Second is that defining a kind of new rule, shown by what another PDCCH transmission rules were transmitted as Fig. 9 b are exemplary It is intended to, i.e. the PDCCH is provided solely for the configuration of configured transmission, such as MCS, and the transmission initial position of data is still on the side of GF resources Boundary chooses resource according to preset criterion, i.e., a cycle (n-th to n+7 slot, period be 8 slot) n-th+ 1 slot network equipment issues the configuration parameter of PDCCH, and the initial position of the transmission of data is not by the shadow of the configuration of PDCCH It rings, transmission data, such as the n-th+2 slot can be started in any one slot of GF resource pools.

For latter rule, terminal device needs to distinguish configuration to be to be directed to common transmission or URLLC business, Ke Yixin A Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell Radio Network Temporary Identifier, C-RNTI) is defined, Such as URLLC-C-RNTI.When receiving the scrambled PDCCH of URLLC-C-RNTI, terminal device, which is known, only receives configuration, transmission Initial position it is related to GF；Identify that the configuration is needle when being either resolved to URLLC transmission specific configurations in PDCCH To URLLC business.I.e. in this fashion, the rule further includes user identifier, and the user identifier is used to indicate the end End equipment is according to the initial position transmission data of the transfer resource for configuring selection of the configured transmission, and terminal device is according to institute The initial position for stating the transfer resource for configuring selection of configured transmission starts to continuously transmit the data.

Further, if it is to be broadcast the message to carry by SI that more sets, which retransmit rule,.In conjunction with existing protocol to minimum SI's It discusses, since above-mentioned rule is only for URLLC, the information reception for URLLC can be triggered by following manner:Work as receipts When PDCCH scrambled to new URLLC-C-RNTI, the reception of corresponding SI information is triggered；Either it is resolved in PDCCH Triggering receives when for the URLLC specific configuration parameters transmitted or specific DCI.

Realization method above essentially describes the configuration for retransmitting rule, and the configuration for just passing rule is described below.It carries out just Two parameters need to be configured by passing the configuration of rule：Exempting from configuration conflict in authorization resources avoids the selection of resource in window and the window accurate Then.

The similar configuration for retransmitting criterion can be carried by SI broadcast messages, RRC signaling, MAC CE or DCI.This realization method The SI methods sent are only provided, the configuration mode of remaining message is similar with criterion is retransmitted：

First, cell new in SI is defined, the control to transmitting criterion in conflict avoidance window and window is provided：

Element in the cell is described in detail as follows shown in table 11：

The definition for the cell element for just passing rule is configured in 11 SI of table

Then, it increases criterion list newly, protocol conventions need to be used, as shown in table 12 below：

Table 12 just passes list of rules

Number	Description
		0	It is randomly selected in window
1	Window size on UE ID moulds

Be described separately above and retransmitted rule, just passed rule and recurring rule is separately configured, can also to retransmit rule, It just passes rule and recurring rule carries out joint configuration.It is provided below and retransmits rule, just passes the joint configuration of regular and recurring rule Realization method：

In one implementation, if not differentiating between transport-type, each transmission is only focused on, then combining configuration mode can be with It is：The configured transmission used is transmitted in definition each time, is just passed and is repeated then can not differentiate between, or even retransmits.The network equipment pair It is separately configured in each transmission, such as URLLCRepetitionConfigList is only configured according to the realization method of front；Terminal Equipment only needs, according to being pre-configured with, to initiate transmission every time.The i.e. described rule includes the configuration for the configured transmission transmitted each time, The transmission each time includes following at least one transmission：It just passes, repeat to transmit and retransmits.

In another realization method, if explicit differentiation is wanted just to pass and retransmit, the boundary of both definition is needed.To same One continuously transmitting for data packet may have following multiple combinations situations：It just passes and retransmits, or just pass and repeat and retransmit.

If 1) only just pass and retransmit

The network equipment configures URLLCRepetitionConfigList and URLLCInitialConfig simultaneously.Wherein, The boundary that URLLCCollisonAvodanceWindow is defined is exactly the first boundary passed and retransmit.

If 2) include just to pass simultaneously, the repetition and re-transmission just passed needs the boundary for increasing a repetition transmission, further There are two types of modes：

Mode 1, the configuration of display --- a repetition transmission window is for example further added by by URLLCInitialConfig, The transmission window that repeats is the time slot just reached between the repetition end of transmission, and the rule is used to indicate It is retransmitted after the repetition transmission window.Concrete configuration is as follows：

The network equipment configure simultaneously URLLCRepetitionConfigList described in above example and URLLCInitialConfig。

Wherein, URLLCInitialConfig makees following correct with respect to above embodiment：

Each element is defined as follows shown in table 13 in the cell：

Table 13 just passes, repeats to transmit and retransmit the cell element definition of the rule configuration jointly controlled
