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.

In addition, in embodiments of the present invention, the network equipment and terminal device carry out used time-frequency money during uplink Source (for example, first running time-frequency resource) is including at least two time quantums.

In embodiments of the present invention, running time-frequency resource (in other words, the network equipment and terminal used in the communication system 100 The running time-frequency resource that equipment is used based on competition mechanism) can be licensed spectrum resource, that is, the communication system of the embodiment of the present invention 100 be the communication system that can use licensed band, also, each terminal device in system 100 may be used competitive way and make With the running time-frequency resource of the licensed band.

License running time-frequency resource generally requires the running time-frequency resource that the wireless committee's examination ＆ approval of country or place can just use, no Homologous ray such as LTE system and WiFi system are provided alternatively, the system that different operators include cannot be shared using license time-frequency Source.

In addition, in some embodiments of the embodiment of the present invention, the network equipment be capable of providing one or more exempt to permit it is small Area's (alternatively, being referred to as exempting to permit carrier wave) and one or more licensed cells (carry alternatively, being referred to as license Wave).

In addition, it is necessary to explanation, the information transmission for exempting from LTE system in licensed band can be without fixed frame structure. In short, access network equipment such as base station or cell can be loaded according to downlink business and/or uplink service loads, Huo Zheqi His Consideration is determined after robbing and accounting for exempting from licensed spectrum resource, determines the transmission duration and/or uplink information of downlink information Transmission duration.Further, access network equipment can be adjusted flexibly after robbing and accounting for exempting from licensed spectrum resource including downlink The number of the time quantum (i.e. downgoing time unit) of information, the time quantum (i.e. upstream time unit) including uplink information The uplink that transmission duration, each upstream time unit for the downlink information that number, each downgoing time unit include include The transmission duration of information.

Also, exempt to introduce transmission opportunity (TxOP, Transmission in licensed band in the frame structure of LTE system Opportunity concept), wherein, transmission opportunity is referred to as burst transfer (Transmission Burst), one It can include downlink burst in TxOP and transmit (DL Transmission Burst, Downlink Transmission Burst) And/or uplink burst transmission (UL Transmission Burst, Uplink Transmission Burst).

Wherein, downlink burst transmission (is referred to as：" downlink burst data transmission " or " transmission of downlink burst information ") It can include：Cell (Cell) under access network equipment (such as eNB) or access network equipment accounts for exempting from licensed band resource robbing Later, by do not need to again by competition mechanism (for example, LBT) in a manner of using this exempt from licensed band resource progress information transmit (in other words, data transmission).The time span of one downlink burst transmission is no more than the access network equipment (or the cell) at this Exempt from not needing to the maximum time that can be continuously transmitted by competition mechanism again in licensed band resource, which can also Referred to as maximum channel holding time (MCOT, Maximum Channel Occupied Time).The length of MCOT can be with region Regulations are related, for example, in Japan, MCOT can be equal to 4ms；In Europe, MCOT can be equal to 8ms either 10ms or 13ms.Alternatively, the competition mechanism that the length of MCOT can also be used with snooping equipment (such as access network equipment or terminal device) It is related, it is however generally that, time of intercept is shorter, and MCOT is shorter.Again alternatively, the length of MCOT can also be with the grade of service of transmission It is related.In embodiments of the present invention, MCOT can also be determined by other factors, be not specifically limited.

It should be noted that in the foregoing description, " by do not need to again by competition mechanism in a manner of using this exempt from license frequency The information transmission that Duan Ziyuan is carried out " can include, and access network equipment or cell are after robbing and accounting for exempting from licensed band resource, at this Exempt from actually to send in licensed band resource in the time of information or in MCOT, do not need to assess this by competition mechanism again and exempt to be permitted Can the resource of frequency range whether can be used.For example, by taking the downlink burst transmission that first TxOP includes as an example, transmitted from the downlink burst In second subframe start, which, which does not need to assess this by competition mechanism again, exempts from whether licensed band resource can be used.It changes Sentence is talked about, and before downlink burst data transmission, needs first to determine that this is exempted from licensed spectrum resource and can be used, once the downlink burst Start to transmit, the availability for exempting from licensed spectrum resource can not be evaluated and tested again, until the downlink burst data end of transmission.

Alternatively, " by do not need to again by competition mechanism in a manner of using this exempt from licensed band resource progress information transmit " Can also include, access network equipment or cell after robbing and accounting for exempting from licensed band resource, this exempt from it is real in licensed band resource Border is sent in the time of information or in MCOT, it may not be necessary to be considered with different coexisting for system and using competition mechanism, still It is contemplated that with coexisting for homologous ray and using competition mechanism, here, the competition mechanism used for coexisting for homologous ray can After being included in and rob and account for exempting from licensed band resource, sending in the time of information or MCOT, the specific time can be included Unit (or idle time quantum), herein in specific time quantum, base station or cell can be transmitted with Stop message (or can To stop sending information), herein in specific time quantum, base station or cell can carry out channel sense and exempt to evaluate and test this again Whether licensed spectrum resource can be used, and can not also carry out channel sense in specific time quantum, continue sending information Time or MCOT in send information.For example, out of, downlink burst transmission start to finish time range, access network equipment It can stop sending information for a period of time in position at any time.Here, for LTE system, non-LTE system can be seen as Different system, such as WLAN (WLAN, Wireless Local Area Network) system or using Wireless Fidelity The system of (WiFi, Wireless Fidelity) technology；LTE system can be seen as homologous ray, either belong to same operator LTE system still fall within the LTE systems of different operators, homologous ray can be seen as.Here, LTE system include base station and/ Or terminal device.

Similarly, uplink burst transmission (is referred to as：" uplink burst data transmission " or " uplink burst information passes It is defeated ") it can include：Terminal device after robbing and accounting for exempting from licensed band resource, with do not need to again by competition mechanism (for example, LBT the information that mode) exempts from the progress of licensed band resource using this is transmitted.For single terminal equipment, uplink burst The time span of transmission can be not more than the MCOT exempted from this in licensed band resource, alternatively, the time to uplink burst transmission Length can also have other restrictions.The information that uplink burst transmission can include single user is transmitted, and can also include multiple use The information transmission at family.From access network equipment side, uplink burst transmission can be the uplink information transmission included in TxOP.

Also, for terminal equipment side " by do not need to again by competition mechanism in a manner of using this exempt from licensed band provide The understanding of the information transmission that source carries out " is identical with access network equipment side, and this will not be repeated here.

Wherein, for terminal device, homologous ray is also understood that have same services cell with the terminal device Or the terminal device of serving Access equipment.Uplink burst transmission further includes, and access network equipment accounts for exempting from licensed band money robbing After source, do not need to exempt from the time range that licensed band transmits into row information using this by competition mechanism in the access network equipment It is interior, based on specific time delay (such as time delay based on 4ms), from first sub-frame of uplink that can be dispatched to can Transmitted with the information that terminal device between the last one sub-frame of uplink for being dispatched to carries out, for example, from first sub-frame of uplink to Time range between the last one sub-frame of uplink transmits corresponding time range for the uplink burst.In the embodiment of the present invention In, the time span of the sub-frame of uplink that can be dispatched to for uplink information transmission can be less than 1ms.

In embodiments of the present invention, the time span of a TxOP can be not more than downlink burst transmission and can allow most Under big transmission time length is either transmitted the maximum transmission time length that can allow or is not more than no more than uplink burst The maximum transmission time length that row burst transfer allows transmits the sum of maximum time length allowed with uplink burst, alternatively, one The time span of a burst transfer can exempt from the MCOT in licensed band resource no more than this.For example, locking equipment is given for one, Either access network equipment or terminal device or other equipment after robbing and accounting for exempting from licensed band resource, do not need to The maximum time length that data can be transmitted by competition mechanism again is 8ms (corresponding MCOT above-mentioned), that is, a TxOP Even if including DL transmission burst and UL transmission burst simultaneously, a TxOP is (in other words, Transmission Burst) maximum transmission time length be also 8ms.So as to which some appearances may be used in uplink burst transmission Terminal device is easily made to rob and account for the competition mechanism that (in other words, competition to) exempts from licensed band resource.

As previously mentioned, the information for exempting from LTE system in licensed band is transmitted without fixed frame structure, can include with down toward One item missing：The duration of different downlink burst transmission can be different, and the duration of different uplink burst transmission can be different, different The durations of downlink burst transmission that include of TxOP (can be adjacent or non-conterminous) can be different, it is different The duration of uplink burst transmission that TxOP includes can be different, and the duration of different TxOP can be different.In the embodiment of the present invention In, downlink burst transmission duration include, the finish time from the initial time of downlink burst to the downlink burst when Between length；The duration of uplink burst transmission includes, the finish time from the initial time of uplink burst to the uplink burst Time span.

In embodiments of the present invention, uplink can include uplink burst transmission, referred to as " uplink burst ".Terminal is set It is standby before uplink is carried out, need to first pass through for example, the modes such as LBT confirm running time-frequency resource that the network equipment dispatches (for example, The resource exempted from licensed band of network equipment scheduling) whether can be used, as specifically where LBT is being carried out, the present invention is not It is specifically limited.

In embodiments of the present invention, a uplink burst transmission can include one or more time quantums.

Also, when a uplink burst transmission includes multiple time quantums, multiple times in uplink burst transmission It can also be continuously discrete (for example, being separated with time interval between certain adjacent time quantums) that unit, which can be, this hair Bright embodiment is simultaneously not particularly limited.

Optionally, in multiple continuous time quantums that each uplink burst transmission includes, the time of each time quantum is long It spends identical.

That is, in embodiments of the present invention, each time quantum in a uplink burst transmission can be including identical symbol The time quantum of number number.

For example, the length of each time quantum in a uplink burst transmission is a subframe.

In another example the length of each time quantum in a uplink burst transmission is 2 symbols.

Alternatively, optionally, in multiple continuous time quantums that each uplink burst transmission includes, at least two times are single The time span of member differs.

That is, in embodiments of the present invention, it is at least single there are two the time in each time quantum in a uplink burst transmission Member includes different symbol numbers.

For example, in the transmission of uplink burst in addition to first time quantum and/or the last one time quantum when Between unit time span be 1ms (i.e. 1 subframe).Also, first time quantum in the transmission of uplink burst when Between length can be less than 1ms；Alternatively, the time span of the last one time quantum in a uplink burst transmission can be less than 1ms；Alternatively, the time span of first time quantum and the last one time quantum in a uplink burst transmission is respectively less than 1ms.It should be noted that the time span of above-mentioned first time quantum and the last one time quantum can be identical, also may be used With difference.

In another example the time span of a time quantum in the transmission of uplink burst can be less than 8 it is arbitrary just Integer symbol, such as the transmission of uplink burst include 6 time quantums, and the corresponding time span of each time quantum is 3 symbols, 2 symbols, 2 symbols, 2 symbols, 2 symbols, 3 symbols.

In embodiments of the present invention, the time quantum in a burst transfer can be used for transmitting the number of a terminal device According to, can be used for transmission multiple terminal devices data, the embodiment of the present invention is simultaneously not particularly limited, for example, same access net The modes such as frequency division multiplexing or time division multiplexing or space division multiplexing or code division multiplexing may be used in the multiple terminal devices that equipment is serviced By the time quantum in a burst transfer, the data of access network equipment transmission are received.In another example same access network equipment The multiple terminal devices serviced may be used the modes such as frequency division multiplexing or time division multiplexing or space division multiplexing or code division multiplexing and pass through Time quantum in one burst transfer, to the access network equipment transmission data.

In embodiments of the present invention, each burst transfer can be divide in advance it is (in other words, static or be semi-statically configured ), that is, the top management equipment of each burst transfer communication system divides and notifies each access network equipment, alternatively, each burst passes Defeated dividing mode can also be as defined in communication protocol, alternatively, the dividing mode of each burst transfer passes through default setting or pipe The modes such as reason person's setting are stored in advance in each access network equipment.For example, exempting from licensed spectrum resource for identical, net is respectively accessed Equipment can exempt from licensed spectrum resource by time-multiplexed mode using this, and specific corresponding time use scope can lead to The division of top management equipment is crossed, in the time use scope of division, it is also desirable to be evaluated and tested by channel and exempt from licensed spectrum using this Resource.

Alternatively, in embodiments of the present invention, each burst transfer can also be each access network equipment independently determine (or It says, dynamic change), that is, each access network equipment may be used competitive way and determine workable time quantum, and will be competed The one or more time quantums arrived are as one or more burst transfers, for example, access network equipment can be more by what is competed A time quantum configuration is in same burst transfer.

In the following, the transmission process of the uplink reference signals of the embodiment of the present invention is described in detail with reference to Fig. 2.Fig. 2 is The schematic interaction figure of an example of the transmission process of the uplink reference signals of the embodiment of the present invention.

As shown in Fig. 2, in S210, the network equipment can be that terminal device #A (that is, an example of terminal device) distribution is used for Carry out the running time-frequency resource #A (that is, an example of the first running time-frequency resource) of uplink.

Wherein, running time-frequency resource #A includes two or more time quantums in the time domain, hereinafter, for the ease of reason Solution and explanation, the running time-frequency resource #A time quantums included are denoted as：Time quantum #1~time quantum #N, N is whole more than 1 Number.

In addition, running time-frequency resource #A is the running time-frequency resource used based on competition mechanism, specifically, although the time it is single First #1~time quantum #N (in other words, the running time-frequency resource #A) is that the network equipment distributes to terminal device #A, and still, terminal is set Standby #A still needs using competitive way using time quantum #1~time quantum #N, and in other words, terminal device #A only can The running time-frequency resource to (in other words, rob and account for) is competed by terminal device #A using in time quantum #1~time quantum #N.

For example, non-limiting as example, running time-frequency resource #A can be the running time-frequency resource exempted from licensed band.

It should be noted that in embodiments of the present invention, time quantum #1~time quantum #N can be continuous, it should Can be spaced between certain adjacent time quantums of time quantum #1~time quantum #N there are one or multiple time quantums or Symbol, the present invention are simultaneously not particularly limited.

In addition, in embodiments of the present invention, running time-frequency resource #A can be that the network equipment individually distributes to terminal device # The running time-frequency resource of A；Multiple ends including terminal device #A are distributed to alternatively, running time-frequency resource #A can be the network equipment The running time-frequency resource of end equipment, the embodiment of the present invention are simultaneously not particularly limited.

Also, in embodiments of the present invention, running time-frequency resource #A can be that the network equipment is determining terminal device #A needs It is later terminal device #A distribution to carry out uplink；Alternatively, running time-frequency resource #A can be the network equipment for example, at the end When end equipment #A accesses the cell of network equipment offer, distribute to terminal device #A's；Again alternatively, running time-frequency resource #A can be with The network equipment for example, competition to communication system provides it is part or all of exempt from license running time-frequency resource when, from what is competed Exempt to permit to determine in running time-frequency resource and this distributes to terminal device #A, the embodiment of the present invention is simultaneously not particularly limited.

It is non-limiting as example, for example, the network equipment can be by resource scheduling information by running time-frequency resource #A's Instruction information is sent to terminal device #A, so as to which terminal device #A can determine to need using running time-frequency resource #A (that is, the time Unit #1~time quantum #N) in compete running time-frequency resource progress uplink.

Alternatively, for example, the initial position of running time-frequency resource #A can with the network equipment carry out downlink transfer when use when Frequency resource has correspondence, for example, when terminal device #A needs to carry out uplink, can currently carry out the network equipment Downlink transfer terminate after (after last symbol used in the downlink transfer that in other words, the network equipment currently carries out) It is spaced initial position of the time-domain position of X symbol of specified quantity as running time-frequency resource #A.Wherein, above-mentioned specified quantity X can To be as defined in communication system or communication protocol, notify to give terminal device #A alternatively, specified quantity X can also be the network equipment , the present invention is simultaneously not particularly limited.

Also, running time-frequency resource #A size (for example, the size in time-domain resource, specifically, be time quantum #1~ The total quantity N of time quantum #N) can be corresponding with the quantity of uplink carried out required for terminal device #A, alternatively, should The size of running time-frequency resource #A can also be specified value Y, wherein, above-mentioned specified value Y can be communication system or communication protocol regulation , it notifies to give terminal device #A alternatively, specified value Y can also be the network equipment, the present invention is simultaneously not particularly limited.

Sizes of the running time-frequency resource #A on frequency domain can arbitrarily be set as needed, also, running time-frequency resource #A is in frequency Size on domain can be as defined in communication system or communication protocol or the network equipment determines and notifies to set to terminal Standby #A's, the present invention is simultaneously not particularly limited.

Terminal device can determine running time-frequency resource #A as a result, specifically, terminal device can determine that running time-frequency resource #A exists Included each time quantum in time domain, that is, time quantum #1~time quantum #N.Specifically, terminal device can determine The total quantity of time quantum #1~time quantum #N and position.

In S220, terminal device #A may be used for example, the modes such as LBT, carry out for running time-frequency resource #A (for example, when Between unit #1~time quantum #N) competition, with from running time-frequency resource #A (for example, time quantum #1~time quantum #N) really The time quantum that fixed terminal device #A can be used.

It should be noted that if terminal device #A is not competed to any time unit, uplink can not be carried out, Uplink reference signals cannot be sent, therefore, in the case where terminal device #A can carry out uplink, terminal device #A can Compete at least one of time quantum #1~time quantum #N time quantums, that is, can carry out uplink in terminal device #A The last one time that terminal device #A can be at least competed in time quantum #1~time quantum #N in the case of transmission is single Member, that is, time quantum #N.

Hereinafter, for the ease of understanding and illustrating, it will be competing by terminal device #A in time quantum #1~time quantum #N The time quantum striven is denoted as：Time quantum # α~time quantum #N, wherein, α is greater than or equal to 1 integer.

It should be noted that in embodiments of the present invention, time quantum # α~time quantum #N can be continuous, it should Can be spaced between certain adjacent time quantums of time quantum # α~time quantum #N there are one or multiple time quantums or Symbol, the present invention are simultaneously not particularly limited.

It can determine to carry from the time quantum # α~time quantum #N competed in S230, terminal device #A The time quantum (that is, an example of first time unit) of uplink reference signals, hereinafter, for the ease of understanding and illustrating, by the time It is denoted as in unit # α~time quantum #N for carrying the time quantum of uplink reference signals：Time quantum #T.

It should be noted that in embodiments of the present invention, uplink reference signals are included for uplink data channels demodulation Demodulated reference signal (Demodulation Reference Signal, DMRS), the detection reference letter measured for up channel Any one or more signal in signals such as number (Sounding reference signal, SRS).

Non-limiting as example, in embodiments of the present invention, which is located on a time quantum, That is, in the embodiment of the present invention, only there are one uplink ginseng can be carried on time quantum in time quantum # α~time quantum #N Signal is examined, for example, the uplink reference signals can be used for the number on each time quantum in time quantum # α~time quantum #N According to demodulation.Wherein, the number for the reference signal sequence which includes and time quantum # α~time quantum #N The maximum number of plies of middle data transmission is equal.For example, the maximum number of plies of data transmission is 2 in time quantum # α~time quantum #N Layer, then the uplink reference signals include 2 reference signal sequences.It is it should be noted that upper on same symbol when being located at When row reference signal includes multiple reference signal sequences, frequency division can be added to ensure multiple references by code point or frequency division or code point Orthogonality between signal sequence.

Alternatively, in embodiments of the present invention, which can be located on multiple time quantums, that is, the present invention In embodiment, can have in time quantum # α~time quantum #N can carry the uplink reference signals on multiple time quantums, For example, the uplink reference signals on a time quantum can be used for the part-time list in time quantum # α~time quantum #N The demodulation of data in member；Alternatively, the uplink reference signals on multiple time quantums can combine do channel estimation and for when Between data in unit # α~time quantum #N on each time quantum demodulation.

Non-limiting as example, multiple uplink reference signals can be carried on multiple symbols, and multiple symbol belongs to same One time quantum.For example, demodulated reference signal and detection reference signal are carried simultaneously on unit at the same time, wherein demodulation ginseng It examines signal and detection reference signal is located at different symbols.

In embodiments of the present invention, time quantum #T can be time quantum # α (that is, situation 1), alternatively, the time is single First #T can be time quantum #N (that is, situation 2), in the following, above-mentioned two situations are described in detail respectively.

Situation 1

Specifically, as shown in figure 3, in embodiments of the present invention, as the rule for determining time quantum #T, Ke Yilie 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 Show an example of information), in other words, terminal device #A is used to indicate by terminal device #A energy in time quantum #1~time quantum #N Enough (in time sequencing) first time quantums (that is, time quantum # α) competed are believed as the instruction of time quantum #T Breath (that is, another example of the first instruction information) is sent to terminal device #A.

So as to, terminal device #A can be based on the first instruction information, determine to determine time quantum #T using rule #1, That is, terminal device #A can be based on the first instruction information, it can by terminal device #A in time quantum #1~time quantum #N First time quantum of (in the time sequencing) competed (that is, time quantum # α) is as time quantum #T.

Alternatively, in embodiments of the present invention, the network equipment can serve to indicate that terminal device #A by time quantum #1~when Between instruction of (in time sequencing) first time quantum (that is, time quantum #1) as time quantum #T in unit #N Information (that is, an example of the second instruction information) is sent to terminal device #A.

Time quantum #1 is arrived since terminal device #A can not guarantee competition, when terminal device #A is received During the second instruction information, terminal device #A can determine to determine time quantum #T using regular #1, that is, when terminal device #A connects When receiving the second instruction information, terminal device #A can compete terminal device #A in time quantum #1~time quantum #N First time quantum of (in the time sequencing) arrived (that is, time quantum # α) is as time quantum #T.

Non-limiting as example, in embodiments of the present invention, the network equipment may determine that terminal device #A can be competed Into time quantum #1~time quantum #N (in time sequencing) positioned at one or more time quantums of front end (for example, when Between first in time sequencing time quantum in unit #1~time quantum #N) possibility (for example, probability), and When the network equipment determines that the possibility (for example, probability) is larger, the first instruction information or the second finger are issued to terminal device #A Show information.

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 belongs to MCOT used in the network equipment, if it is decided that result is "Yes", then the network equipment can determine that terminal is set 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 MCOT used in the network equipment, then the network equipment can be issued to terminal device #A this first instruction information or second instruction Information.

It should be understood that the network equipment listed above determines whether the method for issuing the first instruction information or the second instruction information Be merely illustrative with process, the present invention is not limited to this, for example, the network equipment can also judge time quantum #1~ Whether the quantity that time quantum #N belongs to the time quantum of MCOT used in the network equipment is greater than or equal to preset threshold value # 1, if it is decided that result is "Yes", then it is single can to determine that terminal device #A can compete time quantum #1~time for the network equipment One or more time quantums in first #N (in time sequencing) positioned at front end are (for example, time quantum #1~time quantum #N In first in time sequencing time quantum) possibility it is larger, so as to, the network equipment can be under terminal device #A Send out the first instruction information or the second instruction information.Also, above-mentioned threshold value #1 can be as defined in communication system or communication protocol Value or manufacturer or telecom operators are arranged in the network equipment, the present invention are simultaneously not particularly limited.

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 Used in the network equipment during MCOT, terminal device competes the possibility to the first time quantum in first running time-frequency resource It is larger, in this case, being joined by the way that network equipment instruction terminal equipment is made to send uplink on first time quantum competed Signal is examined, is conducive to the transmission of uplink reference signals, and is conducive to the network equipment and detects or demodulate as early as possible uplink reference signals, And then reduce the processing delay of uplink.For example, the network equipment can be sentenced by detecting the existence of uplink reference signals The initial time unit of disconnected uplink.

In addition, in the case where time quantum # α include multiple symbols, when terminal device #A can also further determine that this 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.

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 # α 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 # α, if the time is single First # α include multiple symbols, and first symbol in time quantum # α is for carrying 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, and the last symbol in time quantum # α is for carrying 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, and the position of symbol for being used to carry uplink reference signals in time quantum # α is that the network equipment passes through Signal #A's to terminal device or communication system or communication protocol as defined in value.

Situation 2

Specifically, as shown in figure 4, in embodiments of the present invention, as the rule for determining time quantum #T, Ke Yilie Lift following rule #2.

Regular #2：Time quantum #T can be last (in time sequencing) in time quantum #1~time quantum #N One time quantum, that is, time quantum #N.

It is non-limiting as example, for example, rule #2 can be as defined in communication system or communication protocol, alternatively, should Regular #2 can be that user is input to terminal device #A, then alternatively, rule #2 can be manufacturer or telecom operators' configuration In terminal device #A.

For another example rule #2 can be terminal device #A based on the instruction information from the network equipment (for example, third refers to Show information) it is determining.

Specifically, in embodiments of the present invention, the network equipment can be by the instruction information of rule #2 (that is, third refers to Show an example of information), in other words, be used to indicate terminal device #A by time quantum #1~time quantum #N (in time sequencing On) the last one time quantum (that is, time quantum #N) as time quantum #T instruction information (that is, third indicate information Another example) be sent to terminal device #A.

So as to, terminal device #A can be based on the third and indicate information, determine to determine time quantum #T using rule #2, That is, terminal device #A can be based on the third indicate information, by time quantum #1~time quantum #N (in time sequencing ) the last one time quantum (that is, time quantum #N) is as time quantum #T.

Non-limiting as example, in embodiments of the present invention, the network equipment may determine that terminal device #A can be competed Into time quantum #1~time quantum #N (in time sequencing) positioned at one or more time quantums of front end (for example, when Between first in time sequencing time quantum in unit #1~time quantum #N) possibility (for example, probability), and When the network equipment determines that the possibility (for example, probability) is smaller, third instruction information is issued to terminal device #A.

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 Sequentially) positioned at one or more time quantums of front end (for example, in time quantum #1~time quantum #N in time sequencing 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 Between send ascending control information to the network equipment on unit #T, thus, it is possible to hold uplink reference signals and ascending control information Same time quantum is loaded in, the network equipment can reliably obtain the uplink reference letter for decoding or demodulating ascending control information 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.

In downlink data transmission, in order to which terminal device can be found in the cell and optimization for switching state eventually in time The wireless resource management RRM of end equipment is measured, and the network equipment can be configured to cell and find reference signal (Discovery Reference Signal, DRS).The DRS that DRS occurs in the period of network equipments configuration measures opportunity configuration (DRS Measurement timing configuration, DMTC) it is sent in window, the length of DMTC windows is 6ms.DRS is by leading Synchronizing signal (Primary synchronization signal, PSS), secondary synchronization signal (Secondary Synchronization signal, SSS), public reference signal (Cell-specific Reference Signal, CRS) Composition, can be configured with channel state information reference signals (Channel State Information Reference Signal, CSI-RS).

DRS subframes are sent on licensed spectrum is exempted from there are two types of situation, a kind of situation is that DRS subframes are passed with a downlink burst 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 The transmission schematic diagram of DRS subframes when transmission is not overlapped in time.In order to ensure the signal transmission on licensed spectrum is exempted from Continuity, to prevent other equipment from seizing channel, grey parts represent the stick signal that the network equipment is sent in Fig. 5 (reservation signal)。

In the prior art, when DRS subframes and downlink burst transmission not be overlapped in time, DRS and PDSCH cannot It is multiplexed and sends in DRS subframes, the network equipment can be ensured by sending stick signal in DRS subframes in DRS subframes The continuity of signal transmission, it is relatively low so as to cause the resource utilization exempted from licensed spectrum.

In the following, with reference to Fig. 6, the transmission process of the downlink data of the embodiment of the present invention is described in detail.Fig. 6 is this hair The schematic interaction figure of an example of the transmission process of the downlink data of bright embodiment.

As shown in fig. 6, in S310, the network equipment determines the second running time-frequency resource (for example, running time-frequency resource #B), wherein, this Two running time-frequency resources are the resources found in reference signal DRS subframes, which does not have in time with the transmission of the first downlink burst There is overlapping.

It should be understood that second running time-frequency resource can be the resource exempted from licensed band on frequency domain.

Non-limiting as example, which is not subframe 0 or subframe 5.That is, in embodiments of the present invention, allow DRS subframe numbers are not the multiplexing transmission of progress DRS and downlink data in 0 or 5 subframe.

In S320, the network equipment is sent on second running time-frequency resource for terminal device #B (that is, an example of terminal device) Physical Downlink Shared Channel PDSCH.

It should be understood that in the prior art, when DRS subframes and the first downlink burst transmission not be overlapped in time, DRS A length of 12 symbols when in subframe available for the maximum of signal transmission, that is, 0~symbol of symbol 11, as shown in Figure 5.As example And it is non-limiting, in embodiments of the present invention, which is less than or equal to 7 symbols.I.e. should DRS subframes can be divided into multiple sTTI according to TTI length, and the network equipment carries out the tune of PDSCH according to the sTTI structures of division Degree.

Non-limiting as example, when the corresponding TTI length of second running time-frequency resource is 7 symbol, which can be with Including 2 sTTI, corresponding length is respectively 7 symbols and 5 symbols.Correspondingly, the network equipment can be in 0~symbol of symbol Running time-frequency resource #B1 (that is, an example of the second running time-frequency resource) is dispatched on 6 for PDSCH transmission, is dispatched on 7~symbol of symbol 11 Running time-frequency resource #B2 (that is, another example of the second running time-frequency resource) is for PDSCH transmission.

Non-limiting as example, when the corresponding TTI length of second running time-frequency resource is 2 symbol, which can be with Including 5 sTTI, corresponding length is respectively 3 symbols, 2 symbols, 2 symbols, 2 symbols and 3 symbols, alternatively, right The length answered is respectively 2 symbols, 3 symbols, 2 symbols, 2 symbols and 3 symbols.Correspondingly, the network equipment can root According to above-mentioned sTTI structure dispatchings PDSCH transmission, details are not described herein again.

Non-limiting as example, which does not include being used for transmission synchronization in the DRS subframes in the time domain The symbol of signal.For example, the network equipment is when carrying out downlink data dispatching, not on the symbol 5 and symbol 6 in the DRS subframes Send PDSCH.

It should be understood that in the prior art, when DRS is transmitted in any subframe in 0~subframe of subframe 4, for the DRS The subframe numbers (or, timeslot number) of sequence generation are subframe 0 (or, first time slot of subframe 0, that is, time slot 0)；When DRS is in subframe When being transmitted in any subframe in 5~subframe 9, for the DRS sequences generation subframe numbers (or, timeslot number) for subframe 5 (or, First time slot of subframe 5, that is, time slot 10).It is non-limiting as example, in embodiments of the present invention, add for the PDSCH The subframe numbers (or, timeslot number) for the scrambler sequence generation disturbed and subframe numbers (or, timeslot number) phase generated for the DRS sequences Together.For example, when the PDSCH is transmitted in any subframe in 0~subframe of subframe 4, for the scrambled scrambler sequences of the PDSCH The subframe numbers (or, timeslot number) of generation are subframe 0 (or, first time slot of subframe 0, that is, time slot 0)；When the PDSCH is in subframe When being transmitted in any subframe in 5~subframe 9, for the subframe numbers (or, timeslot number) of the scrambled scrambler sequence generations of the PDSCH For subframe 5 (or, first time slot of subframe 5, that is, time slot 10).

In S330, terminal device #B PDSCH is received on second running time-frequency resource.

Non-limiting as example, in embodiments of the present invention, terminal device #B detects control letter in the DRS subframes Road, and according to the PDSCH indicated on reception second running time-frequency resource of control channel.

When DRS subframes and the first downlink burst transmission not be overlapped in time, by making the network equipment will be in DRS Resource allocation on frame, for downlink data transmission, can improve the resource utilization exempted from licensed spectrum to terminal device.
