The specific example being applied to reference to the method for the transmission control information of the embodiment of the present invention in URLLC business,
The embodiment of the present invention is introduced in further detail.It should be noted that specific example hereafter is just for the sake of help those skilled in the art
Understand the embodiment of the present invention, and the embodiment of the present invention have to be limited to illustrated concrete numerical value or concrete scene.This area skill
Art personnel are according to given specific example, it is clear that can carry out various modifications or change of equal value, such modification or change
Also fall into the range of the embodiment of the present invention.
For the ease of understanding the embodiment of the present invention, the performance indications of URLLC business are introduced first.Preferably to quantify
The performance indications of URLLC business, so as to provide benchmark input and assessment level, third generation partner program to 5G system designs
(3rd Generation Partnership Project, 3GPP) Radio Access Network (Radio Access Network,
RAN) performance indications of URLLC business are defined as below with RAN1 working groups:
Time delay:SDU (Service Data Unit) of the user application layer packet from transmitting terminal wireless protocols stack layer 2/3
Reach the transmission time needed for receiving terminal wireless protocols stack layer 2/3SDU.The user plane time delay requirement of URLLC business is for upper and lower
Row is 0.5ms, and above-mentioned requirements are only applicable to base station and when terminal is not located in discontinuous reception state (DRX).It may be noted that this
In 0.5ms performance requirement refer to the average delay of packet, do not bound with following reliability requirements;
Reliability:Under given channel quality conditions, (L seconds) correctly passes within a certain period of time from transmitting terminal to receiving terminal
The probability of success of defeated certain bit, above-mentioned time are still defined as user application layer packet from transmitting terminal wireless protocols stack layer 2/
3 SDU (Service Data Unit) reaches the time needed for receiving terminal wireless protocols stack layer 2/3SDU.For URLLC industry
Business, an exemplary requirement be reach in 1ms 99.999% reliability.It may be noted that above-mentioned performance indications be only typical case
Value, specific URLLC business may have different demands to reliability, for example some extreme harsh Industry Controls need to arrive at end
Terminal delay time reaches 99.9999999% transmission success probability in 0.25ms.
Power system capacity:The cell maximum throughput that system under the premise of meeting that certain proportion interrupts user can reach,
Here interrupt user and refer to that system can not meet its reliability requirement in certain time delay range.
It will be appreciated by those skilled in the art that the reliability of URLLC service-user control channels is when number of retransmissions is less
The reliability requirement (1%) of down control channel than traditional LTE is higher.And improve one kind of down control channel reliability
Feasible method is to reduce the information bit of down control channel transmission and distribute more running time-frequency resources to it.
In terms of the requirement of URLLC business low time delay performances, a kind of feasible scheduling strategy be to unique user it is more when
Frequency resource allows each bag to be transmitted as early as possible.More running time-frequency resources are distributed to unique user it is also ensured that data pass
Defeated channel coding rate is sufficiently low so as to ensureing the reliability transmitted every time.Such scheduling strategy means in system simultaneously
The number of users of scheduling will not be too many, and the distribution of each user data channel running time-frequency resource is relatively simple, so URLLC business
Control information in the information bit of data channel time-frequency resource allocating can reduce.It is in addition, highly reliable from URLLC business
Property demand see that the requirement of system spectral efficiency is improved using high order modulation to be become not being especially urgent relatively, so control letter
The instruction of code modulation mode in breath can also do certain simplify.
According in the analysis of the indexs such as the above-mentioned reliability to URLLC business and propagation delay time as can be seen that URLLC business
Control information in schedule information bit number it is fewer.And in the prior art, the bit check code of generally use 16 is believed scheduling
Breath is verified.In this case, it is larger to occupy control information compared with the schedule information after simplifying for 16 bit check codes
Expense.So as to which the target for simplifying control information can not be reached.
The method 600 of the transmission control information applied to URLLC business is introduced below, this method 600 can be set by network
It is standby to perform, it can also be performed by the terminal device in D2D communication services.It will hereafter be introduced so that the network equipment performs as an example
Method 600.
S601, the network equipment generate the control information for URLLC business, and the control information includes the scheduling of terminal device
Information and the first identification information, first identification information are the portion identification letter in the identification information of the terminal device
Breath.
S602, the network equipment send the control information to terminal device.
In embodiments of the present invention, marked by carrying the part of terminal device in the control information for URLLC business
Information is known to indicate scheduled terminal device, has simplified control information, and then improves the reliability of transmission control information, is carried
The high efficiency of transmission control information.
Alternatively, the check code that the information of carrying is shown in control information can be included in the control information, can also not
Including the check code.The information of display carrying mainly includes schedule information, due to the scheduling in the control information of URLLC business
The bit number of information is less, so the probability that mistake occurs in schedule information can be reduced.In such a case, it is possible to correspondingly reduce
For verifying the check code of schedule information, or, it might even be possible to without using check code, so as to reach the mesh for simplifying control information
's.It will be appreciated by those skilled in the art that due to the less characteristic of URLLC service dispatching information bit numbers, check code is simplified simultaneously
The reliability of transmission control information is not interfered with.
Alternatively, above-mentioned check code can be CRC code, and above-mentioned CRC code can be less than 16.
Alternatively, above-mentioned first identification information can be contained among control information in manner shown.Or controlling
In the case that packet contains check code, at least part information in the first identification information is contained in check code in a manner of implicit
In, for being scrambled to check code.
For example, as a specific example, above-mentioned control information can include 6 the first identification informations and 8 CRC
Code.Wherein, 6 the first identification informations can be scrambled 8 by way of cover (for example, cyclic extensions cover or plus spot patch position)
On the CRC code of position.
For example, as another specific example, above-mentioned control information can include 10 the first identification informations and 8
CRC code.Wherein, 8 bit identification information in 10 the first identification informations can implicitly be contained in CRC code by way of scrambling
In.The bit identification information of residue 2 in 10 bit identification information can be carried among control information in manner shown.
Alternatively, because in the scheduling strategy of URLLC business, the number of users that system is dispatched is less, so controlling simultaneously
Whole identification informations of terminal device that can be scheduled without carrying in information, but only need in the control information carry and be adjusted
The portion identification information of the terminal device of degree.Control information is simplified so as to reach, and then improves the reliable of transmission control information
The purpose of property.
In order to make it easy to understand, the method for the schedule information simplified in URLLC business in control information is introduced below.URLLC
Schedule information in business can the HARQ processes including terminal device, new and old Data Identification, the running time-frequency resource point of data channel
Match somebody with somebody, the information such as transport block size and retransmitted redundant version.Wherein, time-frequency resource allocating information can only include time domain or frequency
The resource allocation information in domain, i.e. terminal device when domain scheduling or the unit of frequency domain dispatching can fix, in this case
The resource allocation information of terminal device can only include frequency domain resource or time-domain resource distribution information.
More resource is distributed in RULLC business for unique user, i.e. the combining form of resource allocation is less.For example, make
For an example, Fig. 6 gives the example of the system bandwidth distribution in a URLLC business, and system bandwidth is assigned as limited
Some subbands, the frequency domain resource distribution of terminal device only exist limited several possibility.In figure 6, overall system bandwidth is allocated to
Two subbands, the possibility of frequency domain resource distribution only has 3 kinds, so the bit number of terminal device resource allocation is 2.Wherein, it is sub
The number of band can both pre-define according to system bandwidth, can also be configured by the network equipment by high-level signaling.
In addition, the size of the transmission block of terminal device can also define a limited number of kind, i.e., if the high-rise data reached
Less than the size of physical layer transmission block, high-rise packet needs zero padding.In addition, the signaling instruction of transport block size and transmission block
Size specifically mapping can also pass through high-level signaling configuration realize.For example, Fig. 7 be the embodiment of the present invention configuration transmission block it is big
Small schematic diagram.In the figure 7, the size for four kinds of possible transmission blocks that physical layer can carry, i.e. physical layer transmission are defined
Only support the size of a limited number of kind of transmission block.
It was found from Fig. 6 and Fig. 7 example, the schedule information of URLLC business can include less bit after simplifying
Number.So as to simplify control information.
In embodiments of the present invention, the schedule information and terminal device in the control information by simplifying URLLC business
Identification information, with reduce control information occupancy bit, and then improve transmission control information reliability, improve transmission
The efficiency of control information.
