Specific embodiment

Technical scheme is done below in conjunction with Figure of description and specific embodiment and further explain in detail State.

Embodiment of the method one：

As shown in Fig. 2 the present embodiment provides a kind of information processing method, methods described includes：

Step S110：When uplink instruction is received, start the first timer；

Step S120：After first timer expired, start the second timer；

Step S130：In the second timer timing time, physical down transmission control channel is monitored PDCCH。

Can be applicable in UE in the information processing method described in the present embodiment.Mention in step S110 Uplink indicate can be carried on PDCCH channels in the PDCCH information that sends.The up biography Defeated to indicate for indicating that UE carries out transmitting uplink data, like this, base station will receive the number that UE sends According to.

In step s 110 after receiving the uplink and indicating, start the first timer, described the One timer can be uplink hybrid automatic repeat request timer UL HARQ RTT Timer.First meter When device will for trigger the second timer startup.When implementing, in the timing of first timer The PDCCH channels can be monitored in time, it is also possible to be not listening to the PDCCH channels, but extremely Few corresponding retransmit of uplink for indicating triggering without monitoring the uplink.

In the step s 120 after first timer expired, start the second timer.Second timing Device can receive re-transmission timer UL DRX-RetransmissionTimer for upstream discontinuous.

In step s 130 in the second timer timing time, UE will monitor the PDCCH, Like this, if base station has uplink retransmission to indicate, it would be possible to be sent to UE during PDCCH can be carried on, this Sample UE can just be monitored and be detected that the uplink retransmission is indicated, it is known that need to carry out in uplink retransmission execution Row data are retransmitted.

Obviously the described information processing method of the present embodiment, can be good at solving the uplink retransmission instruction biography The problem of defeated failure such that it is able to improve the speed of response for retransmitting.

The implementation of step S110 to step S120 has various, provides following three in the present embodiment Plant achievable mode：

Mode one：

As shown in Figure 3 and Figure 4, methods described includes：

Step S101：The user equipment monitors Physical Uplink Shared Channel PUSCH, forms snoop results；

Step S102：Based on the snoop results, time offset is determined；

Step S120 includes：

In the manner, UE will also monitor Physical Uplink Shared Channel, form snoop results.The PUSCH For the abbreviation of Physical Uplink Shared Channel.Generally the snoop results can be used in the present embodiment really The fixed time offset, it may also be used for determine whether that responding the uplink indicates to carry out upstream data Send.One time span of the time offset correspondence, in the step s 120 will be in first timer Overtime and time-out time is starting second timer after the time offset.

As shown in figure 4, in the waveform shown in Fig. 4, crest represents UE in the activation phase, in the activation phase Interior, UE will monitor the PDCCH, and UE will will be not listening to described in quiet period in the quiet period PDCCH.After the UE receives uplink instruction in the present embodiment, response uplink is indicated Upstream data is sent, if next base station decoding is unsuccessful, will be sent on PDCCH and be sent up heavy Pass and indicate.If UE is switched between activation phase and quiet period according to the DRX cycle shown in Fig. 1, show So it is possible to not receive uplink retransmission instruction.In the diagram because the first timer and the second timer point Do not start, and the PDCCH is monitored in the second timer timing time, equivalent to can increase UE Activation phase, such UE will continue to monitor PDCCH within the newly-increased activation phase, which increases UE Listen to the probability that the uplink retransmission of base station transmission is indicated.UE receives the first biography of base station transmission in the diagram It is designated as one kind that aforementioned uplink is indicated.Contrast Fig. 1 and Fig. 4 understands that script is mourned in silence in FIG It is interim because of the introducing of the first timer and the second timer, the UE switchings in the timing time of the second timer The monitoring of PDCCH is carried out to activator appliance.

In the manner, step S102 may include：

If the snoop results show that PUSCH does, determine that the time offset is equal to the first side-play amount；

Second side-play amount is more than first side-play amount.

The current PUSCH of the busy expressions of the PUSCH is robbed by other UE and be account for resource, is not available for this UE Send the resource of upstream data.Like this, base station would not receive upstream data, this when, base Stand without indicating after further decoding upstream data that UE is retransmitted again, and can be directly in specified transfer resource It is not received by indicating to retransmit during upstream data, therefore the time that this when of base station sends uplink retransmission instruction can Energy can decode the time advance of the transmission of the caused retransmit that fails than receiving upstream data.Therefore This phenomenon analysis is based in the present embodiment, if the PUSCH does in the present embodiment, the time is inclined Shifting is set to the first side-play amount, and the PUSCH spare time is then the second side-play amount.First side-play amount is less than the second side-play amount.

First side-play amount is less than second side-play amount, when illustrating using the first side-play amount, described second Timer can be earlier startup, what the UE can be earlier begins listening for PDCCH.

Obviously by above-mentioned analysis, two kinds of side-play amounts that shift durations are not waited are designed, is can be good at and nothing The communication scenes of line communication match, and as far as possible while UE power consumptions are saved, reduce uplink retransmission and refer to Show the probability of reception failure.

Mode two：

Methods described also includes：

Receive the first configured information；

The timing duration of first timer can be what is be dynamically determined in the present embodiment.In the present embodiment Described in UE can also receive first configured information from base station, according to first configured information, determine The timing duration of first timer.First configured information can directly described first in the present embodiment The timing duration of timer, it is also possible to index information firmly believed including the timing duration of the first timer etc..Example Such as, the timing duration of first timer includes N kinds, plants and be stored respectively in base station and UE in this N, And each is both provided with corresponding index, may include the index, such UE in first configured information After receiving first configured information, the timing duration of first timer can determine that by inquiry.

First configured information can be base station according to its own current load and/or correspondence upstream data Propagation delay time requires what is determined.Current base station feels that the load of itself is heavier, and is currently needed for the business for retransmitting Propagation delay time require relatively low, be not desired to further heavy load, base station oneself will be postponed under sending Row retransmit, this when can be just first timer setting one by first configured information Individual longer timing time.

Specifically such as, the timing duration of first timer includes the first timing duration and the second timing duration； Wherein, the first timing duration is not equal to the second timing duration；

The timing duration for determining first timer based on the configured information, including：Based on described First configured information, using the first timing duration or the second timing duration as first timing The timing duration of device.

The first timing duration and the second timing duration can be all previously stored with base station and UE, When the UE will be using the first timing duration or second timing according to first configured information determination Grow the timing to carry out first timer.In the manner, usual first timer is once overtime, Then start second timer immediately.

The first configured information sent according to base station is dynamically arranged described by the UE described in the manner The long code during timing of one timer, this makes it possible to meet the transmission demand under different radio transmitting scene, tool The characteristics of having realization easy.

Mode three：

Methods described also includes：

Receive the second configured information；

Step S120 includes：

The UE will receive the second configured information from base station in the present embodiment, the configured information indicate the Terminate the time interval between startup during rear and the second timer during one timer, this time interval is It is spaced for the very first time.The duration at this very first time interval can be from 0 to any duration, in this reality One or more subframes are may include generally in applying example.The generally timing of the first timer described in the present embodiment Duration is static state setting, but very first time interval is dynamic change, so can be used for dynamic tune The starting time of whole second timer, to meet the needs of current transmission scene.

It is specific such as, it is described in first timer expired and overtime duration is equal to very first time interval Afterwards, start second timer, including：After first timer expired, start described immediately Two timers；Or after first timer expired, after being spaced N number of subframe, start second timing Device；Wherein, the N is the integer not less than 1.The N can be the numerical value such as 1 or 2 or 3.

Second configured information described in the present embodiment is alternatively load and/or and/or right of the base station based on itself The propagation delay time of upstream data is answered to require what is determined, it is when transmitting uplink data delay requirement height, then described Base station may be indicated by as the fast as possible transmission uplink retransmission, and this when is in order to ensure the UE Be properly received the uplink retransmission to indicate, then may be after the first timer expired, in the time interval of very little Second timer initiation is just controlled, PDCCH is monitored, and uplink data retransmission is completed as soon as possible so as to convenient.

In the present embodiment, the Startup time of first timer is the first Startup time；Second meter When device Startup time be the second Startup time；Between first Startup time and second Startup time Time interval be the second time interval；Second time interval is indicated according to the transmission uplink To the time determination needed for the duration and the decoding upstream data completed needed for transmitting uplink data.

To in the second time interval between second Startup time, UE may be needed first Startup time Upstream data to be sent to base station, base station needs to decode upstream data and determine the need for according to decoded result Send uplink retransmission to indicate, and uplink is sent when needing and sending uplink retransmission instruction indicate.Therefore at this In embodiment arrange the timing duration of first timer, the timing duration of second timer, when Between side-play amount and very first time interval at least one when, can be by estimating second time It is spaced to determine.

Methods described also includes：

UE is not being heard on PDCCH in the timing time of second timer in the present embodiment Have information transfer, then the second timer will timing always, until timing time-out then timing stop, illustrating now There is very big probability to be transmitting uplink data success, uplink data retransmission need not be carried out.If listening to described Information on PDCCH, if being necessary to carry out uplink retransmission, will hold in the information that the PDCCH is carried The uplink retransmission information is loaded with, if there is no need to carry out uplink retransmission, UE also there is no need again in original This quiet period is kept for the activation phase to carry out PDCCH monitorings, therefore second timer stops timing, institute State PDCCH described in UE stopping degree monitoring, to save the power consumption of UE as far as possible, extend the standby of UE Duration.

Can be stored with the local storage medium of UE described in the present embodiment first timer and described The configuration information of two timers, the configuration information may be based on communication protocol and be stored in advance in the UE, Can also the UE in advance from base station send information in receive.Specifically such as, the configuration information holds UE is sent in being loaded in PDCCH, and the UE obtains the configuration information by detecting the PDCCH.

Certainly the first configured information described in the present embodiment and second configured information can be logical for the base station Cross dedicated signaling and be sent to UE, it is also possible to same message is together carried on the uplink configured information UE is transferred to, like this, the UE is just connect while the uplink instruction is received First configured information or second configured information is have received, is facilitated the UE and is started described first Timer and second timer.

Embodiment of the method two：

As shown in figure 5, the present embodiment provides a kind of information processing method, methods described includes：

Step S210：The first timer and the second timer is configured, configuration information is formed；Wherein, it is described to match somebody with somebody Confidence cease for control user equipment receive uplink indicate after, be respectively started the first timer and Second timer；

Step S220：The configuration information is sent to into user equipment.

Information processing method described in the present embodiment is can be applicable in base station.Described first count in the present embodiment When device and second timer be base station dynamic configuration, and define configuration information.For example base station is based on Communication protocol is configured with based on the instruction of upper layer network element and defines the configuration information.

The configuration information is sent to into UE in step S220, like this, facilitates user according to described Configuration information starts first timer and the second timer, preferably realizes the retransmission process of upstream data.

The system message or wireless link that configuration information described in the present embodiment can be sent by base station connects RRC Message is broadcast to all UE, it is also possible to individually issued the UE for needing to carry out transmitting uplink data by base station.

The formation of the configuration information has various, at least three kinds optional modes presented below：

Optional mode one：

The configuration information is opened after including the timing duration of first timer and first timer expired Move the time offset of second timer.During concrete implementation, the time offset can be wrapped The first side-play amount and the second side-play amount is included, snoop results of the UE by basis to channel select prime number first to offset Amount or second side-play amount.If typically described snoop results show that PUSCH does, described first is selected Side-play amount；If the snoop results show that the PUSCH is not busy, the second side-play amount is selected.

Mode two：

The configuration information includes at least two timing durations of first timer.First timer Timing duration be at least configured with two kinds.

Mode three：

The configuration information starts the very first time of second timer after including first timer expired Interval.The very first time is spaced corresponding time interval scope can be from 0 to N number of subframe.

In the present embodiment, when the configuration information includes at least two timing durations of first timer, Methods described may also include：Send the first instruction for indicating the timing duration for selecting first timer Information.First configured information will indicate that UE selects the timing duration of first timer.

In the present embodiment, start described second after the configuration information includes first timer expired When the very first time of timer is spaced, methods described also includes：Send for indicating to select the very first time Second configured information at interval.After second configured information is used for indicating the first timer expired, the second timer is opened The interval duration at the dynamic very first time interval.

Herein, first configured information and/or second configured information can be base stations according to certainly The parameter determinations such as the propagation delay time requirement of the load condition and/or upstream data of body.Like this, Neng Goudong The starting time of second timer of control of state, that is, control UE and be switched to the activation phase to monitor PDCCH, together When also can consider well data transmission quality require and base station the information such as load condition, balance well Relation between three.

As further improvement of this embodiment, as shown in fig. 6, step S110 includes：

Step S111：According to sub-frame configuration, it is determined that sending the transmission time of the uplink instruction to reception Duration interval between uplink transmission data；

Step S112：It is determined that the process time needed for the decoding upstream data；

Very first time interval can be 0 in the present embodiment, i.e., described first timer is once overtime, institute State the second timer immediately to start, the very first time interval can also be the duration of N number of subframe, because no matter It is uplink or downlink transfer, is all probably with subframe as unit of time, with N number of subframe as described The very first time is spaced, and can be good at mutually suiting with the scene of radio communication, same bigger several with having The characteristics of rate receives the uplink retransmission and indicates.

Additionally, the Startup time of first timer is the first Startup time；Second timer is opened The dynamic moment is the second Startup time；Between the time between first Startup time and second Startup time It is divided into the second time interval；Second time interval is indicated on completing according to the transmission uplink What the time needed for duration and the decoding upstream data needed for row data transfer determined.Like this, energy It is enough to ensure that UE has the quiet period time as much as possible as far as possible, to reduce power consumption of terminal.

Certainly, when implementing, second timing unit 120 will be in second timer When the time in listen to the information of the PDCCH or second timer expired, stop timing.So If, it is possible to reduce UE is because monitoring the power consumption that the PDCCH is produced.

Apparatus embodiments two：

As shown in figure 8, present example provides a kind of base station, the base station includes：

Dispensing unit 210, for configuring the first timer and the second timer, forms configuration information；Wherein, The configuration information is used for controlling user equipment after receiving uplink and indicating, is respectively started the first meter When device and second timer；

Transmitting element 220, for being sent to user equipment by the configuration information.

Base station described in the present embodiment can be evolved base station eNB etc..

The concrete structure of dispensing unit 210 described in the present embodiment may include processor or process circuit.It is described The concrete structure of processor or process circuit can be found in apparatus embodiments one.The processor or process electricity The formation of above-mentioned configuration information can be realized by performing specific instruction in road.

The transmitting element 220 may include that what transmission antenna or transmission antenna array constituted eats dishes without rice or wine, and such as X2 connects Mouthful, dedicated for carrying out information exchange with UE.

The configuration information is to give UE by base station configuration concurrency in the present embodiment, like this, base Stand and the configuration information is sent by configuration concurrency, can increase the probability that uplink retransmission indicates transmission success.

The composition of the configuration information has many kinds, and several optional informations presented below are constituted,

Or

Above-mentioned three kinds of configuration informations control the first timer and second timing of UE with different information structures The startup and timing of device, and monitor PDCCH, the characteristics of with realizing easy.

Specifically such as, the transmitting element 220 is additionally operable to include first timing when the configuration information At least two timing durations of device, send first for indicating the timing duration for selecting first timer Configured information；Or start second timer after the configuration information includes first timer expired Very first time when being spaced, send for indicating to select second configured information at very first time interval.

Certainly the time offset may have multiple, when this when may have multiple in the configuration information Between offset information, UE will select a time offset according to the snoop results to channel.

The dispensing unit 210 forms the structure of the configuration information various, presented below a kind of achievable Structure.Specific such as the dispensing unit can be used for according to sub-frame configuration, it is determined that sending the up biography The time that sends of defeated instruction is spaced to the duration received between uplink transmission data；It is determined that the decoding upper line number According to required process time；Based on duration interval and the process time, configuration starts first meter When device the first Startup time to start the second timer the second Startup time between the second time interval； First timer and second timer are configured according to second time interval and the configuration is formed Information.Here sub-frame configuration can be time division multiplex TDD sub-frame configuration, it is also possible to frequency division multiplexing TDD Frame is configured.

In a word, present embodiments provide a kind of base station can be collectively forming with the UE in apparatus embodiments one it is logical Letter system, is communicated using the communication system, and the probability with retransmit transmission success is high, during re-transmission The features such as prolonging little.

Below in conjunction with above-mentioned any embodiment, there is provided several specific examples.

Example one：

There are three kinds of configuration modes base station for each retransmission process configuration UL HARQ RTT Timer of UE. Mode one：A HARQ RTT timer-ul is configured for certain HARQ process, the timer includes Two parts, a standing part HARQ RTT timer-ulc, one is time offset offset. If HARQ RTT timer-ul are overtime, start DRX-RetransmissionTimer-ul.This In DRX-RetransmissionTimer-ul be aforesaid second timer.Here UL HARQ RTT Timer-ulc are regarded as aforementioned first timer.Certainly when implementing, it is also possible to will The HARQ RTT timer-ul are entirely considered as first timer.

HARQ RTT timer-ulc are defined as：When UE receives an instruction uplink During PDCCH, start HARQ RTT Timer-ulc, until time-out during first timer. Offset originates in the HARQ RTT Timer-ulc stop timings,

The time offset is being offset1 or offset2.UE using which offset (offset1 or Offset2) depend on channel-monitoring result.

When UE completes uplink (i.e. channel-monitoring result is not busy situation) in the specified time, make HARQ RTT timer-ulc+ are equal to offset1, the i.e. length of HARQ RTT timer-ul offset1；When UE fails to complete uplink in the specified time that (i.e. channel-monitoring result is busy feelings Condition), HARQ RTT are equal to using offset2, the i.e. length of HARQ RTT timer-ul timer-ulc+offset2.Here offset1 can be second side-play amount, and the offset2 can be First side-play amount.

Offset 2 is shorter than offset 1, because base station receives upstream data without from UE, therefore need not Decoding process is carried out to upstream data, i.e., without base station end processing delay, usual base station is if desired to upper line number 3ms may typically need according to being decoded.

Method without base station end processing delay can be：Base station listens to energy less than certain by energy measuring Individual threshold value, then it is assumed that UE could not send upstream data on the ascending resource for indicating.Now, base station End need not carry out the decoding operate of data block, so as to reduce processing delay.

It should be noted that the HARQ RTT timer-ul in being originally example are in timing course In, the UE may be at the activation phase and can also be in quiet period.

Mode two：A fixed HARQ RTT timer-ul is configured for certain HARQ process, should The setting of HARQ RTT timer-ul refers to existing protocol standard.Here HARQ RTT Timer-ul i.e. equivalent to previous embodiment in the first timer.

HARQ RTT timer-ul are configurable to one of following two values, and timer time-out starts DRX-RetransmissionTimer-ul：DRX-RetransmissionTimer-ul is aforementioned second meter When device.

The time span of HARQ RTT timer-ul is equal to HARQ RTT timer-ul-1：And The time span of the HARQ RTT timer-ul-1 can be equal to HARQ RTT timer-ulc+ offset1。

The time span of HARQ RTT timer-ul is equal to HARQ RTT timer-ul-2：And The time span of the HARQ RTT timer-ul-2 is equal to HARQ RTT timer-ulc+ offset2。

If the time span of the HARQ RTT timer-ul-1 can be first in previous embodiment Timing duration, then when the time span of the HARQ RTT timer-ul-2 is second timing It is long.If the time span of the HARQ RTT timer-ul-2 is the first timing duration, The time span of the HARQ RTT timer-ul-1 is the second timing duration.

Mode three：The length of HARQ RTT timer-ul is equal to HARQ RTT in method one timer-ulc.If adopting the HARQ RTT timer-ulcr, can be in HARQ RTT timer-ulc Start DRX-RetransmissionTimer-ul after time-out at once, it is also possible to which is made from first descending son Frame starts to start DRX-RetransmissionTimer-ul.

When UE receives the information that one carries the PDCCH that uplink is indicated, start HARQ RTT Timer-ul。

If base station occupation mode one is UE arranges HARQ RTT Timer-ul, what the step started It is HARQ RTT Timer-ulc；According to channel-monitoring result, which offset UE is determined using.Letter Road snoop results are the spare time, using offset1；Channel-monitoring result is busy, using offset2.

If base station occupation mode two is UE arranges HARQ RTT Timer-ul, the HARQ RTT Timer-ul is a fixed value.Its value is HARQ RTT Timer-ul-1 or HARQ RTT Timer-ul-2.HARQ RTT Timer-ul-1 or HARQ RTT Timer-ul-2 are adopted particularly, The first configured information can be sent to determine according to base station.

If base station occupation mode three is UE arranges HARQ RTT Timer-ul, the HARQ RTT Timer-ul is a fixed value, and its value can be RTT Timer-ulc in mode one.

HARQ RTT Timer-ul time-out starts DRX-RetransmissionTimer-ul, at this During the timing of DRX-RetransmissionTimer-ul, PDCCH channels are monitored.

If base station occupation mode three is UE arranges HARQ RTT Timer-ul, UE can be made to exist Start DRX-RetransmissionTimer-ul at once after HARQ RTT Timer-ul are overtime, it is also possible to UE is made to start DRX-RetransmissionTimer-ul when starting from first descending sub frame.

When PDCCH listens to message or DRX-RetransmissionTimer-ul is overtime, stop DRX-RetransmissionTimer-ul。

Example two：

Aforementioned manner used below one forms configuration information.

The sub-frame configuration formed using offset1 and offset2 respectively for base station LAA eNB shown in Fig. 9.

As shown in figure 9, UE receives up grant information UL Grant in subframe 8, start HARQ RTT Timer-ulc (the timing duration of HARQ RTT Timer-ulc here is equal to 5ms), and prepare Sub-frame of uplink 2 sends upstream data UL Data.Before UL Data are sent, UE needs monitor channel. If channel-monitoring result is the spare time, that is, represent that UE can send UL Data in specified resource, because This UE is using offset1 (offset1 here is equal to 3ms)；If channel-monitoring result is busy, i.e., Represent that UE can not send UL Data in specified resource, therefore UE adopts offset2 (here Offset2 is equal to 0ms).Here described up grant information can be to inform the transmission of UE upstream datas Resource information.This resource information may include the temporal information of transfer resource and band information.

The time of usual 1 subframe is 1ms, it is clear that knowable to the upper figure of Fig. 9, in HARQ RTT After Timer-ulc timing terminates, after offset by 3ms, DRX-RetransmissionTimer-ul starts, and It is in figure below of Fig. 9, after HARQ RTT Timer-ulc timing terminates, described DRX-RetransmissionTimer-ul starts immediately.

Example three：

The configuration of HARQ RTT timer-ul-1 and HARQ RTT timer-ul-2 refers to existing There is agreement TS36.213.Allocation list of the following table 1 for TDD radio frames, shows there is the nothing in table 7 kinds of configuration modes of the subframe of line frame in, this 7 kinds of configuration mode number consecutivelies are 0 to 6.In form D represents descending sub frame；S represents special subframe；U represents sub-frame of uplink.

Table 1

For 6 kinds of sub-frame configurations of TDD up-link UL/ downlink DL radio frames, if UE have received UL grant or the automatic Qin's retransmit information (Physcial of physical mixed in subframe n Hybrid automatic request Indicator Channel PHICH), then UE can be sent out in subframe n+k Send corresponding PUSCH.Wherein k value is shown in Table 2.

Table 2

Up UL grant informations are received in subframe 6, understands that k is equal to 6 by inquiry table 2, then will Be spaced 5 subframes after send up UL data, after upstream data has been sent, base station need into The operations such as row upstream data decoding, generally decoding need 3ms or so, equivalent to 3 subframes, therefore at this In this example, HARQ RTT timer-ul-1 are set to 10ms.

Up grant information is received in subframe 9, is understood that k is 4 by inquiry table 2,3 will be spaced Upstream data is sent after individual subframe, after upstream data has been sent, base station needs to carry out upstream data The operation such as decoding, generally decoding need 3ms or so, and equivalent to 3 subframes, and base station needs are descending Send up grant information next time in subframe, therefore the HARQ RTT in book example Timer-ul-1 is set to 10ms.

Up grant information is received in subframe 1, by inquiry table 2 understand k be equal to 6, then will Upstream data is sent after 5 subframes, after upstream data has been sent, base station needs to carry out line number According to the operation such as decoding, generally decoding needs 3ms or so, equivalent to 3 subframes, therefore in book example HARQ RTT timer-ul-1 are set to 10ms.

Up grant information is received in subframe 4, by inquiry table 2 understand k be equal to 4, then will Upstream data is sent after 3 subframes, after upstream data has been sent, base station needs to carry out line number According to the operation such as decoding, generally decoding needs 3ms or so, equivalent to 3 subframes, therefore in book example HARQ RTT timer-ul-1 are set to 10ms.

As shown in figure 11, below in sub-frame configuration mode 1 as an example, HARQ RTT timer-ul-2 are carried out Configuration, formed configuration information.

Up grant information is received in subframe 6, understands that k is equal to 6 by inquiry table 2, no channel It is available for sending upstream data, base station need not carry out the operation such as upstream data decoding, therefore in book example HARQ RTT timer-ul-2 are set to 8ms.

Up grant information is received in subframe 9, understands that k is 4 by inquiry table 2, no channel can For sending upstream data, base station need not carry out the operation such as upstream data decoding, therefore in book example HARQ RTT timer-ul-2 are set to 5ms.

Up grant information is received in subframe 1, understands that k is equal to 6 by inquiry table 2, no channel It is available for sending upstream data, base station need not carry out the operation such as upstream data decoding, therefore in book example HARQ RTT timer-ul-2 are set to 8ms.

Up grant information is received in subframe 4, understands that k is equal to 4 by inquiry table 2, without transmission Upstream data, base station need not carry out upstream data decoding etc. and operate, therefore the HARQ in book example RTT timer-ul-2 are set to 5ms.

Example three：

As shown in figure 12, in sub-frame configuration mode 2 as an example, HARQ RTT timer-ul-1 are configured, Form configuration information.

If subframe 8 receives UL grant informations, by the k knowable to 2 that tables look-up equal to 4, midfeather 3 Individual subframe sends up UL data, and base station decoding upstream data may need the time through 3 subframes, Therefore HARQ RTT timer-ul-1 are set to into 8ms, next just directly initiate DRX-RetransmissionTimer-ul。

If subframe 3 receives grant information, by tabling look-up, equal to 4, midfeather 3 is sub for k knowable to 2 Frame sends up UL data, and base station decoding upstream data may need the time through 3 subframes, therefore HARQ RTT timer-ul-1 are set to into 8ms, are next just directly initiated DRX-RetransmissionTimer-ul。
