The embodiment of the present application in order to facilitate understanding, firstly, the relevant technologies being related to application embodiment are briefly described.

Exempting from authorized transmissions mode basic principle is: regulation some authorization resources of exempting from base station are for multiple terminal devices progress uplink Data transmission, these resources may be what base station was semi-statically configured, and terminal device randomly chooses one or more resource units in exempting from authorization resources and transmit data when there is data transmission.

Authorized transmissions mechanism is exempted from using the prior art, if there is a large amount of terminal needs to send data, then multiple terminal devices are very high using the identical probability for exempting from authorization resources unit transmission data simultaneously, i.e. collision probability is higher, a large amount of re-transmissions are easy to cause, is unfavorable for terminal device and efficiently carries out data transmission.

Based on the above, the embodiment of the present application provides a kind of transmission method competition-based, is conducive to improve terminal device in the efficiency for exempting from authorization resources transmitting data.

Fig. 1 is the application scenario diagram suitable for the embodiment of the present application.As shown in Figure 1, the application scenarios include base station 101.The application scenarios further include the multiple terminal devices 102 within 101 coverage area of base station.Base station 101 can be communicated with terminal device 102.It should be understood that only using two terminal devices 102 in 101 coverage area of base station as example in Fig. 1.Obviously, there can also be more terminal devices 102 in the coverage area of base station 101.

Base station in following embodiment can be with the terminal device 102 in corresponding diagram 1 or similar to the multiple terminal devices of terminal device 102 with the base station 101 in corresponding diagram 1, terminal device.

Specifically, base station can specify that some authorization resources of exempting from for multiple terminals progress transmitting uplink data.In the embodiment of the present application, this, which exempts from authorization resources, can be understood as resource area, and multiple terminal devices are able to use at least partly resource in the resource area and send data.

For convenience, " competitive transfer resource region (contention-based transmission area, CTA) " can also be denoted as by being somebody's turn to do " exempting from authorization resources ".

Fig. 2 is the schematic figure of an example of the CTA suitable for the embodiment of the present application.As shown in Fig. 2, base station can be using a subband in system bandwidth as CTA.Frequency spectrum resource is divided into time domain unit one by one in time dimension.Wherein, which can be time slot (slot), perhaps symbol etc. is also possible to multiple subframes, multiple time slots, multiple mini-slot or multiple symbols etc. to mini-slot (mini-slot).

When CTA occupies a subband, all resources on this subband may not all belong to CTA.For example, the time-frequency domain position of some fixations may have (for example, subframe primary sign and terminating symbol) special-purpose in each subframe.Such as, the time-frequency domain position of some fixations in each subframe is for sending system information block (system information block, SIB), or for sending Downlink Control Information (downlink control information, DCI) etc..There is the resource of special-purpose to be not belonging to CTA for this on subband.Based on this, the CTA resource in each subframe can be one or more rectangular resource regions.

The resource area that the subband or CTA that CTA is occupied include can be adjusted as needed by base station.

For example, base station can send CTA resource information by broadcast message (for example, SIB or DCI).Terminal device obtains the relevant information of CTA by receiving the broadcast message.

Optionally an example, the CTA can be used by one group of terminal device.It is used for example, base station can configure the first CTA for terminal device #A, terminal device #B and terminal device #C, terminal device #D is not available the first CTA, and terminal device #D can not send data based on competition on exempting from authorization resources.

Optionally another example, the CTA can be uplink small data resource area competition-based.For example, there is the terminal device of uplink small data transmission demand in all terminal devices that base station is serviced, it can compete the CTA and send uplink small data.

Optionally, CTA can be in the time-domain resource periodically occurred, such as each subframe one and take the period of entire carrier bandwidths, and multiple units are then divided on frequency domain, and each unit occupies one or more subcarriers.Time domain and frequency domain can also be combined, the CTA of each period (such as subframe) occupies one or more rectangle running time-frequency resources region, CTA It is interior to divide smaller time/frequency source block as transmission unit.That is, the CTA can periodically occur.For example, the period of CTA can be subframe, a subframe is defined as 1 millisecond of time span, i.e., can all have CTA resource in each millisecond.By taking the period of CTA is two subframes as an example, which can be located in the subframe that subframe number is #0, #2, #4, #6 and #8.

Further, CTA can be divided into the transmission unit of multiple fixed sizes on time-frequency domain, it can will be somebody's turn to do " transmission unit of fixed size " and be denoted as " competitive transmission unit (contention-based transmission unit; CTU) ", that is, the CTA may include multiple CTU.Can be orthogonal in time-frequency domain between multiple CTU, mutually it can also overlap or be overlapped in time-frequency domain and be realized by code domain etc. orthogonal.In other words, various multiple access technologies can be used in CTU in CTA, such as, orthogonal frequency-time multiple access (orthogonal frequency division multiple access, OFDMA), Sparse Code multiple access accesses (sparse code multiple acces, SCMA), non-orthogonal multiple access (non-orthogonal multiple access, NOMA) etc..Under various multiple access technologies, the resource in CTA is all divided into several CTU.

Fig. 3 is the schematic diagram using an example of the division mode of CTU under SCMA multiple access technology suitable for the embodiment of the present application.As shown in figure 3, four resource blocks (resource block, RB) can be used as one group, each group of RB includes six CTU in logic.Each CTU practical occupancy two RB, each RB are repeated to occupy by three CTU.Each CTU in every group of CTU has unique code word (code), be overlapped in this way a running time-frequency resource unit signal can be realized by code word it is orthogonal.

There may be the CTA of plurality of specifications, CTU's in the CTA of every kind of specification is in different size, that is, the CTA having is suitble to transmit the data of very little, and CTU is smaller, and some CTA are suitble to transmit slightly larger data, and CTU is bigger.If only a kind of CTA of specification, UE can not be transmitted all data using a CTU, is transmitted at this point, UE can choose at least two CTU, or data are divided, transmitted in two times.The specific division mode of CTU and UE are not subject to the limits fixed using the specific transmission process the application of CTU.

Hereinafter, being described in detail in conjunction with competition-based transmission method of Fig. 4-Fig. 7 to the embodiment of the present application.

Fig. 4 is the schematic interaction figure according to an example of the transmission method competition-based 200 of the embodiment of the present application.It should be understood that Fig. 4 shows the detailed step or operation of method 200, but these steps or operation are only examples, the embodiment of the present application can also be performed other operations, various operations in Fig. 4 deformation or only execute part operation in Fig. 4.

This method 200 can be executed by base station and terminal device.Wherein, base station and terminal device can respectively correspond the base station 101 in above-mentioned communication scenes and terminal device 102.As shown in figure 4, this method 200 may include 210,220,230 and 240.

210, at least one terminal device is exempted from authorization resources in the first period to base station transmission data based on competition；Correspondingly, the data exempting from authorization resources on detect at least one terminal device based on competition sent of the base station in first period.

For ease of description, " the exempting from authorization resources of the first period " in the application can be denoted as " the first CTA ".At least one terminal device based on competition on the first CTA to base station send data may include: at least one terminal device each terminal device data are sent to base station by the part CTU in the first CTA.

Multiple terminal devices compete the first CTA, and at least one terminal device of the first CTA of successful contention can send data to base station by the first CTA.

Base station can detect the data that at least one terminal device is sent based on competition on the first CTA.For example, base station can monitor whether each CTU in the first CTA has signal, and the signal on the CTU for having signal in the first CTA is decoded.

220, the base station according to testing result, determines the competition window upper limit value for being equal to the first numerical value, described to be equal to first The competition window upper limit value of numerical value is competed for multiple terminal devices exempts from authorization resources after first period.

For ease of description, " the first upper limit value " will can be denoted as " equal to the competition window upper limit value of the first numerical value ".Base station can detecte the reception condition that data are received on the first CTA, and determine the first upper limit value according to testing result.

The testing result may include the information of a variety of reception conditions on the first CTA that can be used to indicate that base station.

Optionally an example, the testing result may include reception failure number (or quantity of the CTU clashed).

Specifically, if base station listens to signal in a CTU, but the signal cannot be correctly decoded, it is believed that signal reception failure (or clashing in the CTU) on the CTU.Signal reception failure on one CTU can be denoted as primary failure by optionally an example.For example, base station signal reception failure on F CTU in the first CTA, it is believed that base station reception failure number in the first CTA is F times.

Optionally another example, the testing result may include reception failure rate.

Optionally, reception failure rate η can satisfy formula: η=F/Z, wherein F is reception failure number, and Z is the sum for the CTU that the first CTA includes.For example, the first CTA includes Z₁A CTU, the base station know in the Z CTU there is F by detection₁Signal reception failure on a CTU, reception failure rate η=F₁/Z₁。

Optionally, reception failure rate η can satisfy formula: η=F/J, wherein F is reception failure number, and J is the quantity for the CTU that base station listens to signal in the first CTA.For example, the first CTA includes Z CTU, the base station is in the Z₁J in a CTU₁Signal is listened on a CTU, the J₁F in a CTU₁Signal reception failure on a CTU, reception failure rate η=F₁/J₁。

Preferably, η=F/Z is more reasonable as failure rate.

Optionally another example, the testing result can also include receiving number of success.If base station listens to signal in a CTU, and is correctly decoded the signal, it is believed that signal receives successfully on the CTU.Signal on one CTU can be received and successfully be denoted as primary success by optionally an example.For example, base station signal on S CTU in the first CTA receives successfully, it is believed that it is S times that base station receives number of success in the first CTA.

Optionally another example, the testing result can also include successful receiving rate.

Optionally, successful receiving rate λ can satisfy formula: λ=S/Z, wherein S is to receive number of success, and Z is the quantity for the CTU that the first CTA includes.For example, the first CTA includes Z₁The Z is known by detection in a CTU, the base station₁There is S in a CTU₁Signal on a CTU receives successfully, successful receiving rate λ=S₁/Z₁。

Optionally, successful receiving rate λ can satisfy formula: η=S/J, wherein S is to receive number of success, and J is the quantity for the CTU that base station listens to signal in the first CTA.For example, the first CTA includes Z₁A CTU, the base station is in the Z₁J in a CTU₁Signal is listened on a CTU, the J₁S in a CTU₁Signal on a CTU receives successfully, successful receiving rate η=S₁/J₁。

It should be understood that above-mentioned reception failure rate and successful receiving rate can also be determined by other means, can reception failure rate and successful receiving rate determines according to actual conditions, the embodiment of the present application is it is not limited here.

Preferably, using failure rate as adjusting competition window upper limit value according to more reasonable.

By taking testing result includes reception failure number as an example, this 220 may include one of following methods.

Mode #1

Base station can store the corresponding relationship of reception failure number Yu competition window upper limit value regulated quantity.

For ease of description, the corresponding relationship of reception failure number and competition window upper limit value regulated quantity can be denoted as the first corresponding relationship.Optionally, which can be the range of reception failure number and the corresponding relationship of competition window upper limit value regulated quantity.For example, reception failure number is that the first quantity to competition window upper limit value regulated quantity corresponding between the second quantity is equal to Δ W₁, reception failure number is that third quantity to competition window upper limit value corresponding between the 4th quantity is equal to ΔW₂.For example, competition window upper limit value to be adjusted to the minimum value allowed when the frequency of failure is less than 5 times (optionally, base station can store the minimum value that the competition window allows).When the frequency of failure is more than or equal to 5 times less than 10 times, keep existing competition window upper limit value constant.When the frequency of failure is more than or equal to 10 times less than 15 times, competition window upper limit value is being adjusted to 1.5 times of existing value.When the frequency of failure is more than or equal to 15 times less than 20 times, competition window upper limit value is being adjusted to 2 times of existing value.And so on.

Similarly, base station can store corresponding relationship of the reception failure rate (receiving number of success or successful receiving rate) with competition window upper limit value regulated quantity, such as, when failure rate is less than or equal to 1%, competition window upper limit value is adjusted to the minimum value allowed, or is adjusted to the 50% of current competitive window upper limit value tune but is not less than the minimum value allowed.When failure rate, which is greater than 1%, is less than or equal to 2%, keep existing competition window upper limit value constant.When failure rate, which is greater than 2%, is less than or equal to 3%, competition window upper limit value is adjusted to 1.5 times of existing value.When failure rate, which is greater than 3%, is less than or equal to 4%, competition window upper limit value is adjusted to 2 times of existing value.And so on.

The corresponding relationship of above-mentioned complexity can also not be used, and simply delimit a threshold range, such as first threshold is 1%, second threshold 2%.If failure rate is less than (or being equal to) first threshold, competition window upper limit value is adjusted to the minimum value allowed, or is adjusted to 50% or 75% etc. of current competitive window upper limit value but is not less than the minimum value allowed.If failure rate is greater than (or being equal to) first threshold, and is less than (or being equal to) second threshold, then keep existing competition window upper limit value constant.If failure rate is greater than (or being equal to) second threshold, competition window upper limit value is adjusted to 1.5 times or 2 times etc. of existing value.

Mode #2

The competition window upper limit value that base station can be used based on terminal device in the first CTA, determines first upper limit value.

That is, this before 210, this method can also include:

201, base station sends second indication information；Correspondingly, (multiple) terminal device receives the second indication information.

Optionally, base station can send the second indication information by broadcast message.For example, base station can send the second indication information by SIB or DCI.Wherein, the second indication information is used to indicate the competition window upper limit value equal to second value.For ease of description, " the second upper limit value " should can will be denoted as " equal to the competition window upper limit value of second value ".Second upper limit value competes moment #T for terminal device₁Later exempt from authorization resources.Optionally, moment #T₁At the time of can determining the second upper limit value for terminal device.

After terminal device receives second indication information, the second upper limit value competition moment #T of second indication information instruction can be used₁CTA later.That is, the CTA of the second upper limit value competition following sessions can be used after terminal device determines the second upper limit value, it should be appreciated that the period after moment #A included the first period.

This 210 may include:

The data that at least one terminal device is sent according to second upper limit value are detected on the first CTA in the base station.

This 220 may include:

Base station according to testing result, determines competition window upper limit value.Wherein, the competition window upper limit value of the determination can be equal to the second upper limit value or be not equal to the second upper limit value.

For example, the base station determines the first upper limit value, wherein first upper limit value is greater than second upper limit value if the reception failure number is greater than (or being equal to) first thresholding or reception failure rate is greater than (or being equal to) second thresholding.

By taking testing result includes reception failure number as an example, if reception failure number is greater than the first thresholding, illustrate that collision probability is higher on the first CTA, base station can tune up competition window upper limit value, so that the initial value (initial value of counter is described in detail in rear extended meeting) of counter can generate in bigger space, the probability that multiple terminal devices generate the initial value of identical counter will reduce, and can reduce collision probability.

In another example, if the reception failure number is less than (or being equal to) third thresholding or reception failure rate is less than (or being equal to) the 4th thresholding, the base station determines first upper limit value, wherein first upper limit value is less than second upper limit value.

Above-mentioned first threshold value is greater than third threshold value, and the second threshold value is greater than the 4th threshold value.

By taking testing result includes reception failure rate as an example, if reception failure rate is less than third thresholding, illustrate to conflict in the first CTA less, base station can turn competition window upper limit value down, be conducive to terminal device is avoided to keep out of the way in a big way to lead to the CTA wasting of resources.

It should be understood that may not raise (for example, the second upper limit value is adjusted in multiple) when base station is adjusted competition window upper limit value step by step, base station can directly determine first upper limit value according to reception failure number or reception failure rate.How base station according to the second upper limit value determines that the first upper limit value, the embodiment of the present application are not limited thereto.

Similarly, first upper limit value can be determined according at least one of number of success and successful receiving rate and second upper limit value is received.

230, the base station sends the first instruction information according to the competition window upper limit value equal to the first numerical value；Correspondingly, terminal device receives the first instruction information.

Optionally, base station can send the first instruction information by broadcast message.For example, terminal device can send the first instruction information by SIB or DCI.The first instruction information is used to indicate described equal to the first upper limit value.Specifically, the first instruction information can indicate the first upper limit value in several ways in the embodiment of the present application.

Optionally an example, the first instruction information can be with explicit instruction first upper limit value.

Optionally another example, base station and terminal device can known multiple competition window upper limit values, which is one in multiple competition window upper limit value, and base station can send the mark of first upper limit value.

Optionally another example, which can be with implicit instruction first upper limit value.Specifically, competition window upper limit value and upper limit value parameter can satisfy formula: wherein, W is competition window upper limit value to W=f (k), and W > 0, k are upper limit value parameter.First instruction information can indicate determine first upper limit value after the upper limit value parameter, terminal device receive the upper limit value parameter.For example, competition window upper limit value and upper limit value parameter meet formula: w=M*2^k- 1, wherein M is upper limit base value, which can be default value, which can also be the value that base station is notified to terminal device.For example, base station can send the upper limit base value to terminal device if terminal device access base station.In another example base station can periodically broadcast the upper limit base value.It is considered that the upper limit base value known to terminal device.K (k >=0) is upper limit parameter value.The first instruction information can indicate the upper limit parameter value.

Since upper limit parameter value is index, the value range of upper limit parameter value is smaller, the bit number of occupancy is less, compared to first instruction the first upper limit value of information explicit instruction, first instruction information indicates the first upper limit value by instruction upper limit parameter value, the length that the message (for example, broadcast message of carrying the first instruction information) of carrying the first instruction information can be reduced, is conducive to improve the availability of frequency spectrum.

240, terminal device exempts from authorization resources according to first upper limit value, competition.

Specifically, terminal device competes moment #T according to the first upper limit value₂CTA later.Moment #T₂At the time of can be understood as after the first period, moment #T₂It is also understood that terminal device determines (how the subsequent terminal device that will be described in detail is according to competition window upper limit value competition CTA) at the time of the first upper limit value.

With it is above-described similar, base station can detect the data that at least one terminal device is sent based on the first upper limit value on the CTA of the second period.The CTA of the second period can be denoted as the 2nd CTA for ease of description, base station can determine that (next week) competition window upper limit value maintains the first upper limit value constant or be adjusted the first upper limit value to obtain updated competition window upper limit value according to the testing result of the 2nd CTA.

If base station determines the competition window upper limit value (third value for being equal to third value according to the testing result on the 2nd CTA It is unequal with the first numerical value), base station can notify this to be equal to the competition window upper limit value of third value by three instruction information to terminal device.For ease of description, " third upper limit value " will can be denoted as " equal to the competition window upper limit value of third value ".

Maintain the first upper limit value constant if base station determines according to testing result, base station can continue to use the competition of the first upper limit value in next period and exempt from authorization resources without sending instruction information, terminal device.

That is, after terminal device determines the first upper limit value, CTA is competed according to the first upper limit value, until terminal device receives third instruction information, terminal device stops using the first upper limit value competition CTA and using the third upper limit value competition CTA of third instruction information instruction.

In the embodiment of the present application, base station can determine competition window upper limit value (according to reception condition), and indicate the determining competition window upper limit value in base station to terminal device by instruction information, and terminal device competes CTA according to the competition window upper limit value.It should be noted that the instruction information of the embodiment of the present application belongs to same category information, can be sent in the same way.For example, being sent by SIB or DCI.Further, the instruction information of the embodiment of the present application can be indicated either explicitly or implicitly when indicating competition window upper limit value.

Hereinafter, description terminal device competes the detailed process of CTA according to competition window upper limit value.

Fig. 5 is the schematic flow chart that an example of CTA is competed according to the terminal device of the embodiment of the present application.It should be understood that Fig. 5 shows the detailed step or operation that authorization resources are exempted from terminal device competition, but these steps or operation are only examples, and the embodiment of the present application can also be performed other operations or only execute part operation in Fig. 5.

Specifically, terminal device (for example, terminal device #A) may include: according to competition window upper limit value competition CTA

2a, competition window upper limit value W is obtained；

Specifically, terminal device can generate the initial value R of counter when transmitting the first data for the first time at random according to W₀.For example, it is assumed that W is equal to the first numerical value W₁, R₀Value range be [0, W₁]。

2c, terminal device receive the quantity information from base station, which is used to indicate the quantity N for the CTU that current CTA includes.

The quantity of the current CTA CTU for including can be denoted as to the quantity of current CTU for ease of description.

Similar with competition window upper limit value above, which can explicitly or implicitly indicate that the quantity N that current CTU includes, the quantity information can also pass through broadcast message transmission.

It should be understood that the quantity N (N > 0) of the competition window upper limit value W and current CTU can also pass through different broadcast message transmissions by a broadcast message transmission.Optionally, for competition window upper limit value, competition window upper limit value base station when changing can broadcast the multiple competition window upper limit value W of primary or continuous broadcast, and the broadcast cycle of competition window upper limit value may be longer, and competition window upper limit value W, which can be placed in SIB, to be transmitted.For the quantity of current CTU, the quantity of current CTU belongs to periodic data, and base station can be with the quantity of the current CTU of periodic broadcast, and the quantity of current CTU, which can be placed in DCI, to be transmitted.

It should be understood that the quantity of current CTU is not necessarily to periodic broadcast if the quantity of CTU is basically unchanged in the CTA in each period.In the case where the quantity N of current CTU changes compared to the quantity of upper primary CTU, the quantity N of the current CTU of base station broadcast.

The size relation of the quantity N for the CTU that 2d, terminal device judge the value of counter and current CTA includes, if N executes 2e, the value of counter is greater than N and executes 2f if the value of counter is less than or equal to.

2e, terminal device send data at least one CTU in current CTA.

2f, terminal device determination cannot send data, the value of terminal device refresh counter in current CTA.Wherein, the difference between the value of updated counter and the value of the counter before update is N, and terminal device can carry out the competition of next period CTA based on updated value.

For example, it is assumed that the value of nonce counter is R, the R > N, the value of counter can be updated to R'=R-N by terminal device.Wherein, R' is the value of backoff counter after updating, and R is the value of backoff counter before updating, and N is the quantity of current CTU, and whether terminal device can be greater than the quantity of the CTU in next period according to R', compete the CTA in next period.

Optionally, this method can also include:

If 2g, terminal device, in current CTA transmitting data, terminal device judges whether the data sent on current CTA are properly received by base station.

Specifically, terminal device can judge that the data on current CTA are whether to be successfully received in several ways.For example, terminal device determines that the data on current CTA are successfully received if terminal device receives ACK.In another example terminal device determines that the data on current CTA are not successfully received if terminal device receives NACK.For another example determining that the data on current CTA are not successfully received if terminal device does not receive ACK at predetermined time (such as timer expiry).

If 2h, terminal device determine that the data on current CTA are successfully received, the data being successfully received are removed from data buffer zone to be sent, do not need to make other more processing.

If 2i, terminal device determine that the data of the transmission on current CTA are not successfully received, and terminal device does not receive the competition window upper limit value of update, and terminal device executes 2b, and continues the competition of subsequent CTA.

Using the method for the embodiment of the present application, terminal device can generate the initial value of counter at random according to competition window upper limit value, and according to the size relation of the value of counter and the quantity of current CTU, it is determined whether send data on current CTA, can reduce collision probability.Such as, assuming that the first upper limit value is equal to 100, 80 terminal devices have the demand that data are sent on the 2nd CTA, it include 50 CTU on 2nd CTA, 80 terminal devices can generate the initial value of counter at random according to the first upper limit value, the initial value for the counter that some terminal device generates in 80 terminal devices is greater than 50, terminal device of the initial value of the counter of the generation greater than 50, which is determined, sends data without using the CTU in the 2nd CTA, terminal device of the initial value of the counter of generation less than or equal to 50 can be used the CTU in the 2nd CTA and send data, the quantity of the terminal device of data is sent less than 80 using the CTU of the 2nd CTA, it can reduce the probability that multiple terminal devices send data on identical CTU simultaneously, be conducive to improve number According to the efficiency of transmission.Further, in the embodiment of the present application, base station can advantageously reduce the probability that terminal device sends upstream data conflict according to the timely dynamic Competition adjustment window upper limit value of reception condition, be conducive to improve resource utilization simultaneously, be conducive to the efficiency of improve data transfer.

More than, an example of the transmission method competition-based of the embodiment of the present application is described, hereinafter, another example of the transmission method competition-based of description the embodiment of the present application.

Fig. 6 is another schematic interaction figure according to the transmission method competition-based 300 of the embodiment of the present application.It should be understood that Fig. 6 shows the detailed step or operation of method 300, but these steps or operation are only examples, the embodiment of the present application can also be performed other operations, various operations in Fig. 6 deformation or only execute part operation in Fig. 6.

This method 300 can be executed by base station and terminal device.Wherein, base station and terminal device can respectively correspond the base station 101 in above-mentioned communication scenes and terminal device 102.As shown in fig. 6, this method 300 may include 310,320,330 and 340.

310, base station determines upper limit base value.

Specifically, which determines the value range of competition window upper limit value for terminal device.Base station can determine the upper limit base value based on a variety of criterion.

Optionally an example, the upper limit base value can be equal at least about the pars of the CTA of each period in the two periods CTU for including.Wherein, which can be understood as a cycle of CTA.That is, the upper limit base value can be equal to the quantity of the average CTU of each period (period can be time slot) in a period of time.For example, this includes three periods for a period of time, the quantity for the CTU that period #1 includes is N₁, the quantity for the CTU that period #2 includes is N₂, the quantity for the CTU that period #3 includes is N₃, upper limit base value W=(N₁+N₂+N₃)/3。

Optionally another example, the upper limit base value can be equal at least about L times of the par of the CTA of each period in the two periods CTU for including, wherein L > 1.That is, the upper limit base value can be equal to L times of the quantity of the average CTU of each period (period can be time slot) in a period of time.For example, this includes three periods for a period of time, the quantity for the CTU that period #1 includes is N₁, the quantity for the CTU that period #2 includes is N₂, the quantity for the CTU that period #3 includes is N₃, upper limit base value W=2 (N₁+N₂+N₃)/3。

Optionally another example, the upper limit base value can be equal at least about the maximum quantities of the CTA of period single in the two periods CTU for including.That is, the upper limit base value can be equal to each period maximum CTU quantity in a period of time.For example, this includes three periods for a period of time, the quantity for the CTU that period #1 includes is N₁, the quantity for the CTU that period #2 includes is N₂, the quantity for the CTU that period #3 includes is N₃, N₁<N₃<N₂, upper limit base value W=N₂。

It should be understood that base station, which is also based on other criterion, determines upper limit base value, the embodiment of the present application is it is not limited here.

320, the base station sends instruction information according to the upper limit base value；Correspondingly, terminal device receives the instruction information that base station is sent, wherein the instruction information is used to indicate the upper limit base value.

Optionally, base station can send the instruction information by broadcast message.For example, base station can send the instruction information by SIB or DCI.Specifically, which can indicate certain parameters with the explicit instruction upper limit base value, the instruction information with the implicit instruction upper limit base value, such as the instruction information, and terminal device can calculate the upper limit base value by the parameter.For example, these parameters can be CTA time span, frequency domain width, the Parameters of Time-frequency Field of CTU, code book (Code book) parameter, pilot tone (Pilot) parameter etc. when using SCMA multiple access technology.CTU quantity how is specifically calculated, this is related with specific multiple access technology, does not describe in detail herein.

330, the terminal device determines the value range of the competition window upper limit value according to the upper limit base value of the competition window.

It should be understood that the value range includes minimum value and maximum value.

Optionally, the minimum value can satisfy formula W_min=M-1, wherein W_minEqual to the minimum value, M is equal to the upper limit base value；Or

For example, terminal device receives the instruction information, which can be used formula M*2 if terminal device is after transmitting the second data for the first time and before first time retransmits the second data¹- 1 determines the competition window upper limit value that second of the second data of transmission uses.

Reality can simply use W'=W*2+1, wherein W is current competitive window upper limit value, and W' is updated competition window upper limit value when transmission unsuccessfully tunes up competition window upper limit value.But use W=M*2^p- 1, which calculates new competition window upper limit value, different effects, such as the value of M becomes when transmitting again for the 3rd time, then W=M*2^pThe calculated result of -1 and W'=W*2+1 is different.It is therefore preferred that using W=M*2^pThe new competition window upper limit value of -1 calculating is more reasonable.

340, the terminal device sends data to the base station on exempting from authorization resources according to the value range.

Specifically, terminal device can compete moment #T according to the value range₂CTA later, moment #T₂At the time of can determining minimum value and maximum value for terminal device.

3e, terminal device send data at least one CTU in current CTA.

Specifically, terminal device can select at least one CTU to send upstream data based on certain criterion in current TA.

3f, terminal device determination cannot send data, the value of terminal device refresh counter in current CTA.Wherein, the difference between the value of updated counter and the value of the counter before update is N, and terminal device can carry out the competition of next period CTA based on updated value.

For example, it is assumed that the value of nonce counter is R, the R > N, the value of counter can be updated to R'=R-N by terminal device, and whether be greater than according to R' the quantity of the CTU in next period, compete the CTA in next period.

Optionally, this method can also include:

If 3g, terminal device, in current CTA transmitting data, terminal device judges whether the data sent on current CTA are properly received by base station.

If 3h, terminal device determine that the data on current CTA are successfully received, the data being successfully received are removed from data buffer zone to be sent, do not need to make other more processing.

If 3i, terminal device determine that the data of the transmission on current CTA are not successfully received, and terminal device does not receive the upper limit base value of update, and terminal device expands competition window upper limit value according to current upper limit base value.For example, can be according to M*2^p- 1 expands competition window upper limit value, through competing subsequent CTA according to the competition window upper limit value after expansion.

Specifically, if terminal device sends data on current CTA and is not successfully received, it may be possible to which at least two terminal devices have selected identical CTU to send data, and the data for causing the terminal device to send are not successfully received.The probability clashed again when retransmitting next time to reduce, terminal device can increase the value of competition window upper limit value, and returning to step 3b trial, transmission remains in the data that buffer area is not successfully received again.Since terminal device increases competition window upper limit value, the initial value of counter is generated in bigger space, the initial value that multiple terminal devices generate identical counter will reduce, and can reduce collision probability.Optionally, terminal device can increase competition window upper limit value in several ways, be twice for example, competition window upper limit value can be increased.For example, the competition window upper limit value increased meets W'=2W+1, wherein W' is the competition window upper limit value after increasing, and W is current competition window upper limit value (the competition window upper limit value before increasing)
