In the following, to being described in detail used in the communication system 100 for the running time-frequency resource of wireless communication.
In embodiments of the present invention, the network equipment and terminal device be used for transmission the time-domain resource of information in the time domain can be with
It is divided into multiple time quantums.
Also, in embodiments of the present invention, multiple time quantum can be continuous or it is certain adjacent when
Between preset interval is equipped between unit, the embodiment of the present invention is simultaneously not particularly limited.
In embodiments of the present invention, time quantum can be include for uplink information (for example, upstream data) transmission and/
Or the time quantum of downlink information (for example, downlink data) transmission.
In embodiments of the present invention, the length of a time quantum can arbitrarily be set, and the embodiment of the present invention is not special
It limits.
For example, 1 time quantum can include one or more subframes.
Alternatively, 1 time quantum can include one or more time slots.
Alternatively, 1 time quantum can include one or more symbols.
Alternatively, 1 time quantum can include one or more Transmission Time Interval (Transmission Time
Interval, referred to as " TTI ").
Alternatively, 1 time quantum can include one or more short transmission time interval (short Transmission
Time Interval, referred to as " sTTI ").
In embodiments of the present invention, in the time domain may be used used in communication system 100 for the running time-frequency resource of wireless communication
To be divided into multiple TTI, TTI is the parameter generally used in current communication system (for example, LTE system), is referred to wireless
The thread of schedule data transmission in link.In the prior art, it is generally recognized that 1TTI=1ms.That is, a TTI is one
In other words, the size of two time slots (slot), it is that wireless resource management (scheduling etc.) administers the time to subframe (subframe)
Base unit.
In a communication network, time delay is a crucial performance indicators, while also contributes to the usage experience of user.With
The development of communications protocol, to time delay influence, the scheduling interval of most apparent physical layer is also less and less, in initial WCDMA,
Scheduling interval is 10ms, and scheduling interval contracts in high-speed packet access (High-Speed Packet Access, referred to as " HSPA ")
2ms is short to, scheduling interval (that is, TTI) shortens to 1ms in long term evolution (Long Term Evolution, LTE).
The business demand of small time delay causes physical layer to need to introduce shorter TTI frame structures, between further shortening scheduling
Every raising user experience.For example, in LTE system TTI length can be shorten to from 1ms 1 symbol (symbol) to 1 time slot (including
7 symbols) between.The above-mentioned symbol referred to can be Orthogonal Frequency Division Multiplexing (the Orthogonal Frequency in LTE system
Division Multiplexing, referred to as " OFDM ") symbol or single-carrier frequency division multiple access (Single Carrier-
Frequency Division Multiple Access, referred to as " SC-FDMA ") symbol, it can also be in other communication systems
Symbol.In another example TTI length is again smaller than 1ms in 5G communication systems.
LTE system is in the data transmission based on the TTI that length is 1ms, turnaround time of data transmission under normal circumstances
(Round-Trip Time, referred to as " RTT ") is 8ms.It is assumed that it is compared with the scheduling for the TTI that existing length is 1ms, processing time
It is that equal proportion is reduced, i.e., still follows existing RTT time delays.So, when the data transmission based on the sTTI that length is 0.5ms
In, the RTT of data transmission is 4ms, and relative to the data transmission based on the TTI that length is 1ms, time delay can shorten half, from
And improve user experience.
TTI of the length less than 1ms is properly termed as sTTI.For example, in LTE system, the length of sTTI can be 1~7 symbol
Any one length in number, alternatively, sTTI length can also be the combination of at least two kinds of different lengths in 1~7 symbol, such as
Comprising 6 sTTI in 1ms, each sTTI length can be respectively 3 symbols, 2 symbols, 2 symbols, 2 symbols, 2 symbols,
3 symbols, alternatively, comprising 4 sTTI in 1ms, each sTTI length can be respectively 3 symbols, 4 symbols, 3 symbols, 4
Symbol, each sTTI length can also be the combination of other different lengths.
Also, the sTTI length of uplink can be identical with the sTTI length of downlink, such as the sTTI length and downlink of uplink
STTI length be 2 symbols.
Alternatively, the sTTI length of uplink can be longer than the sTTI length of downlink, such as the sTTI length of uplink is 7 symbols
Number, the sTTI length of downlink is 2 symbols.
Again alternatively, the sTTI length of uplink can be shorter than the sTTI length of downlink, such as the sTTI length of uplink is 4 symbols
Number, the sTTI length of downlink is 1 subframe.
TTI length is less than 1 subframe or the data packet of 1ms is known as short TTI data packets.Short TTI data transmissions on frequency domain,
Can be continuously distributed, it discontinuous can also be distributed.It should be noted that in view of backwards compatibility, base is may be simultaneously present in system
In the data transmission of TTI and the situation of data transmission based on sTTI that length is 1ms.
It in embodiments of the present invention, can be defined by the prior art (such as LTE system) (for example, length is 1ms or length
Degree is more than 1ms) TTI and sTTI be referred to as TTI, also, in embodiments of the present invention, and the length of TTI can be according to practical need
It changes.
It should be understood that the structure of time quantum listed above is merely illustrative, the embodiment of the present invention does not limit especially
It is fixed, can arbitrary change be carried out to the structure of time quantum according to actual needs, for example, the LTE system for not supporting sTTI
For, 1 time quantum can be 1 subframe (Subframe).For another example for supporting the LTE system of sTTI, 1
Time quantum can include 1 sTTI, and in other words, 1 time quantum can include 1 time slot (Slot), and 1 time quantum can
To include one or more (for example, the positive integer less than 7 or positive integer less than 6) symbols;1 time quantum can also
For 1 subframe.
It should be noted that in embodiments of the present invention, time quantum is used for length (in other words, the information of information transmission
Transmit duration) can be 1ms, it might be less that 1ms.In other words, with reference to foregoing description, even for the LTE for not supporting sTTI
For system, when time quantum is represented with subframe, the length in the time quantum for downlink information transmission can be 1ms,
It might be less that 1ms, similarly, the length in the time quantum for uplink information transmission can be 1ms, might be less that
1ms。
Hereinafter, in order to make it easy to understand, in case of a time quantum includes sTTI, to the uplink of the present invention
The transmission process of reference signal illustrates.

Whether the running time-frequency resource is used by other equipment, if the running time-frequency resource is in idle condition, in other words, the running time-frequency resource is not by it
He uses equipment, then terminal device can be communicated using the running time-frequency resource, for example, carrying out uplink etc.;If the time-frequency
Resource is not at idle state, and in other words, which is used by other equipment, then terminal device can not use the time-frequency
Resource.It should be noted that in embodiments of the present invention, the specific method and process of above-mentioned competition mechanism can be with the prior arts

Lift following rule #1.
Regular #1:Time quantum #T can be that terminal device #A can be competed in time quantum #1~time quantum #N
(in time sequencing) first time quantum, that is, time quantum # α.
It is non-limiting as example, for example, rule #1 can be as defined in communication system or communication protocol, alternatively, should
Regular #1 can be that user is input to terminal device #A, then alternatively, rule #1 can be manufacturer or telecom operators' configuration
In terminal device #A.
For another example rule #1 can be terminal device #A based on the instruction information from the network equipment (for example, first refers to
Show information or the second instruction information) it is determining.
Specifically, in embodiments of the present invention, the network equipment can be by the instruction information of rule #1 (that is, first refers to

Standby #A can compete one or more times in time quantum #1~time quantum #N (in time sequencing) positioned at front end
The possibility of unit (for example, first in time sequencing time quantum in time quantum #1~time quantum #N) compared with
Greatly, so as to which the network equipment can issue the first instruction information or the second instruction information to terminal device #A.
That is, if the network equipment judges that one or more of time quantum #1~time quantum #N time quantums belong to

For example, the network equipment can be determined that whether time quantum #1~time quantum #N all belongs to the network equipment institute
The MCOT used, if it is decided that result is "Yes", then the network equipment can determine terminal device by the higher money of use priority
It is (suitable in the time in time quantum #1~time quantum #N to may thereby determine that terminal device #A can be competed for source competitive way
In sequence) positioned at front end one or more time quantums (for example, in time quantum #1~time quantum #N in time sequencing
First time quantum) possibility it is larger, so as to which, the network equipment can issue the first instruction information to terminal device #A
Or second instruction information.
The part or all of time quantum in the first running time-frequency resource terminal of terminal device is distributed to when the network equipment to belong to

Between in unit # α for carrying the symbol of uplink reference signals.
It is non-limiting as example, in the case where time quantum #T can be time quantum # α, if the time is single
First # α include multiple symbols, then the symbol being likely to occur in the time quantum # α that terminal device #A is competed is only time list
The situation of partial symbols in first # α, that is, being likely to occur terminal device #A can not compete in time quantum # α (in time sequencing
On) positioned at front end one or more symbols situation.
In this regard, in embodiments of the present invention, terminal device #A can make terminal device #A in time quantum # α
With first symbol of (in other words, competition is arrived), the symbol as carrying uplink reference signals.

When the network equipment determines that the possibility (for example, probability) is smaller, third instruction information is issued to terminal device #A.
Also, non-limiting as example, the size that in the following manner determines above-mentioned possibility may be used in the network equipment.
Specifically, the network equipment can be determined that one or more of time quantum #1~time quantum #N times list
Whether member is not belonging to MCOT used in the network equipment, if it is decided that result is "Yes", then the network equipment can determine terminal
When equipment #A can be competed in time quantum #1~time quantum #N (in time sequencing) positioned at the one or more of front end
Between unit (for example, first in time sequencing time quantum in time quantum #1~time quantum #N) possibility compared with
It is small, so as to which the network equipment can issue third instruction information to terminal device #A.
That is, if the network equipment judges that one or more of time quantum #1~time quantum #N time quantums do not belong to
In MCOT used in the network equipment, then the network equipment can issue third instruction information to terminal device #A.
It should be understood that the network equipment listed above determines whether that the method and process for issuing third instruction information are merely illustrative
Property explanation, the present invention is not limited to this, for example, the network equipment can also judge that time quantum #1~time quantum #N does not belong to
Whether it is greater than or equal to preset threshold value #2 in the quantity of the time quantum of MCOT used in the network equipment, if it is decided that knot
Fruit is "Yes", then the network equipment can determine terminal device #A can compete in time quantum #1~time quantum #N (when
Between sequentially) positioned at front end one or more time quantums (for example, suitable in the time in time quantum #1~time quantum #N
First time quantum in sequence) possibility it is smaller, so as to which, the network equipment can issue third instruction to terminal device #A
Information.Also, above-mentioned threshold value #2 can be value or manufacturer or telecom operation as defined in communication system or communication protocol
Quotient is arranged in the network equipment, and the present invention is simultaneously not particularly limited.
For example, the network equipment can be determined that whether time quantum #1~time quantum #N is all not belonging to the network equipment
Used MCOT, if it is decided that result is "Yes", then the network equipment can determine that terminal device is relatively low by use priority
Resource contention mode may thereby determine that terminal device #A can be competed in time quantum #1~time quantum #N (in the time

On first time quantum) possibility it is smaller, so as to which, the network equipment can issue third instruction letter to terminal device #A
Breath.
The part or all of time quantum in the first running time-frequency resource terminal of terminal device is distributed to when the network equipment not belong to
When MCOT used in the network equipment, the time quantum that front end is located in terminal device competition to first running time-frequency resource can
Energy property is smaller, in this case, on the last one time quantum by making network equipment instruction terminal the first running time-frequency resource of equipment
Uplink reference signals are sent, the transmission of uplink reference signals can be reliably ensured, further improve the reliability of uplink
And accuracy.
In addition, in the case where time quantum #N includes multiple symbols, when terminal device #A can also further determine that this
Between in unit #N for carrying the symbol of uplink reference signals.
It is non-limiting as example, in the case where time quantum #T can be time quantum #N, if the time is single
First #N includes multiple symbols, then the symbol being likely to occur in the time quantum #N that terminal device #A is competed is only time list
The situation of partial symbols in first #N, that is, being likely to occur terminal device #A can not compete in time quantum #N (in time sequencing
On) positioned at front end one or more symbols situation.
In this regard, in embodiments of the present invention, terminal device #A can make terminal device #A in time quantum #N
With first symbol of (in other words, competition is arrived), the symbol as carrying uplink reference signals.
It should be understood that terminal device #A listed above determine for carry uplink reference signals symbol method and process
It is merely illustrative, the present invention is not limited to this, for example, when terminal device #A competitions to multiple symbols in time quantum #N
In the case of number, terminal device #A can join using any one or more symbols in multiple symbol as carrying uplink
Examine the symbol of signal.
It is non-limiting as example, in the case where time quantum #T can be time quantum #N, if the time is single
First #N includes multiple symbols, and first symbol in time quantum #N is for carrying uplink reference signals.
It is non-limiting as example, in the case where time quantum #T can be time quantum #N, if the time is single
First #N includes multiple symbols, and the last symbol in time quantum #N is for carrying uplink reference signals.
It is non-limiting as example, in the case where time quantum #T can be time quantum #N, if the time is single
First #N includes multiple symbols, and the position of symbol for being used to carry uplink reference signals in time quantum #N is that the network equipment passes through
Signal #A's to terminal device or communication system or communication protocol as defined in value.
As described above, it is determined that time quantum #T is (specifically, be to believe in time quantum #T for carrying uplink reference
Number symbol) after, in S240, terminal device #A can be in time quantum #T (specifically, being used in time quantum #T
Carry uplink reference signals symbol) on to the network equipment send uplink reference signals.
In addition, in embodiments of the present invention, when time quantum #T is time quantum #N, terminal device #A can also when

Number, thus, it is possible to improve the reliability of the transmission of ascending control information.
Also, in embodiments of the present invention, when the network equipment and terminal device #A are based on time quantum # α~time list
When mistake occurs for the uplink of first #N, retransmission process can also be carried out, for example, hybrid automatic repeat-request (Hybrid
Automatic Repeat reQuest, referred to as " HARQ ").
When time quantum #T includes time quantum # α, the process of the retransmission process can be similar to the prior art.
When time quantum #T only include time quantum #N when, due to uplink reference signals be carried on time quantum #1~when
Between the last one time quantum in unit #N, therefore, the network equipment can not determine terminal device #A based on uplink reference signals
Whether All Time unit in time quantum #1~time quantum #N is competed, and in other words, the network equipment can not be based on uplink
Reference signal determines first time quantum in time quantum #1~time quantum #N that terminal device #A is competed, that is, net
Network equipment can not determine that terminal device #A carries out the start bit of time quantum used in uplink based on uplink reference signals
It puts.
In this case, if mistake occurs for transmission, RV used in the re-transmission of above-mentioned upstream data is 0.
That is, when terminal device sends uplink reference signals by the last one time quantum in the first running time-frequency resource,
The network equipment can not determine the initial position of uplink by the uplink reference signals, so as to, when there is error of transmission,
The network equipment can not determine that the error of transmission is since error of transmission caused by channel conditions difference or terminal device do not compete
In first running time-frequency resource positioned at front end part-time unit and caused by error of transmission, in this case, by setting network
It is standby to determine that for RV used in the re-transmission of the upstream data be 0, it is right when can reduce because the reason of can not determine retransmission error
Influence caused by uplink.
Alternatively, if mistake occurs for transmission, the soft bit information of the upstream data of mistake can will occur for the network equipment
It abandons.
That is, when terminal device sends uplink reference signals by the last one time quantum in the first running time-frequency resource,
The network equipment can not determine the initial position of uplink by the uplink reference signals, so as to, when there is error of transmission,
The network equipment can not determine that the error of transmission is since error of transmission caused by channel conditions difference or terminal device do not compete
In first running time-frequency resource positioned at front end part-time unit and caused by error of transmission, in this case, by setting network
The standby soft bit for abandoning the upstream data that error of transmission occurs, can avoid the soft caching of network equipment side from being contaminated, so as to subtract
It is small because the reason of can not determine retransmission error due to uplink is impacted.
By making the last one on the running time-frequency resource used based on competitive way that terminal device distributes in the network equipment
Uplink reference signals are sent on time quantum or by making terminal device in being used based on competitive way of distributing of the network equipment
Uplink reference signals are sent on first time quantum that the terminal device competes in running time-frequency resource, it can be ensured that for carrying
The time quantum of uplink reference signals can be used by terminal device, and then ensure the transmission of uplink reference signals, thus, it is possible to
Improve the reliability and accuracy of uplink.

Defeated to be overlapped in time, in this case, DRS subframes are only capable of being subframe 0 or subframe 5, i.e. it is 0 or 5 that DRS, which is only capable of in subframe numbers,
Subframe on send, in addition, since DRS subframes belong to a downlink burst transmission, PDSCH can also be sent out in DRS subframes
It send.Another situation is that DRS subframes and a downlink burst transmission be not be overlapped in time, since the importance of DRS is higher,
In this case the network equipment can be come in a manner of the higher resource contention of use priority to send DRS competitive resources, and DRS can be with
It is sent in competition to first subframe of resource in DMTC windows, correspondingly, the transmission time of DRS is restricted, and is only capable of occupying DRS
Continuous 12 symbols in subframe, and PDSCH cannot be sent in DRS subframes.Fig. 5 shows DRS subframes and a downlink burst
