Embodiment
For making the object of the invention, technological means and advantage clearer, the present invention is explained further details below in conjunction with accompanying drawing.
Basic thought of the present invention is: the state of affairs according to community user is at first confirmed the transmission cycle period of user's dispatch request and the sub-frame of uplink of transmitting and scheduling request; Then; Utilize dispatch request resource sum and the sub-frame of uplink number of transmitting and scheduling request in the sub-district; Confirm the assignable dispatch request resource of each sub-frame of uplink; The concrete sub-frame of uplink at the dispatch request resource that will confirm again and this resource place is distributed to the user, and notifies user's dispatch request resource, the sub-frame of uplink at this resource place and the transmission cycle period of dispatch request.
Among the present invention during the dispatch request resource of configure user; Utilize available dispatch request resource on the transmission cycle period of dispatch request, the sub-frame of uplink that is used for the transmitting and scheduling request and this sub-frame of uplink as parameter information, be the relevant information of user's configuration schedules request.Like this, the user can be used for the sub-frame of uplink of transmitting and scheduling request according to the transmission cycle period of distributing to self in sending cycle period, utilize the dispatch request resource of distributing to self to upload the uplink scheduling request.
Fig. 1 is the overview flow chart of uplink scheduling request collocation method provided by the invention.As shown in Figure 1, this method comprises:
Wherein, When confirming the transmission cycle period of user SR; Can all users' unifications in the sub-district be configured to identical transmission cycle period, can be each user's configuration transmission cycle period separately according to each user's in the sub-district the user gradation and the grade of service also perhaps.For sending the sub-frame of uplink that is used for the transmitting and scheduling request in the cycle period, then can adopt different definite modes based on FDD system and TDD system.
Wherein, when the base station issues the dispatch request resource, can utilize the dispatch request resource index of corresponding in advance dispatch request resource setting or other identification informations to indicate concrete resource; When issuing the sub-frame of uplink at dispatch request resource place, can utilize subframe deviant or the information of other unique identification subframes of sub-frame of uplink in sending cycle period to indicate; Issue when sending cycle period, can adopt the form of the unified broadcasting in sub-district, also can adopt high-level signaling to notify the mode of each UE respectively.
The information that the user issues based on base station in the step 103, just can the sub-frame of uplink of appointment in sending cycle period on, utilize the dispatch request resource transmission uplink scheduling request that distributes.
So far, uplink scheduling request collocation method flow process provided by the invention finishes.Visible by above-mentioned flow process; The present invention can confirm the transmission cycle period of user's SR, the sub-frame of uplink that is used for the transmitting and scheduling request and dispatch request resource successively; And the above-mentioned information that will confirm notifies to corresponding user, thereby can realize the configuration of dispatch request.
Above-mentioned is the collocation method flow process of uplink scheduling request; In above-mentioned flow process,, do not use within a certain period of time when the dispatch request resource of distributing to certain user; The base station can discharge the dispatch request resource of this distribution, so that other users can utilize this dispatch request resource to send dispatch request.
Through specific embodiment further explain is done in concrete realization of the present invention below.In the present embodiment, utilize the subframe deviant of sub-frame of uplink in sending cycle period to indicate the sub-frame of uplink at dispatch request place, utilize preset dispatch request resource index to indicate concrete dispatch request resource.
Fig. 2 is the collocation method particular flow sheet of uplink scheduling request in the embodiment of the invention.As shown in Figure 2, this method comprises:
When confirming to send cycle period, need consider the problem of expense and time delay simultaneously, the cycle is long, and then expense is little, but the scheduling time delay is big; Cycle is short, and then expense is big, and the scheduling short time delay.
In a kind of optional solution, it is identical that all users' of a sub-district SR sends cycle period, and utilizes the form of system broadcasts to notify the user should send cycle period.
Simultaneously, consider that the requirement to time delay is different in the business demand of different user in the practical application, the SR of different user sends the demand of cycle period also maybe be different; Therefore SR that can different user sends cycle period and is set to difference; Improve the SR configuration flexibility like this, helped making full use of limited SR resource, but need notify the user respectively; Its each self-corresponding SR sends cycle period, certainly will increase overhead.Therefore, need between expense and time delay, obtain a compromise based on the application scenarios of reality.
Among the present invention,, select to send the configuration mode of cycle period particularly, be specially the transmission cycle period that the user confirms SR then at first according to the number of users of each sub-district and user's class of business quantity.
Wherein, the configuration mode that sends cycle period comprises two kinds: first configuration mode is that all users' unifications in the sub-district are configured to identical transmission cycle period; Second configuration mode does, is each user's configuration transmission cycle period separately according to each user's in the sub-district the user gradation and the grade of service.
Preferably, when class of business less when the number of users in the sub-district, the user was also fewer, for example first configuration mode can be selected in the rural area, for all users in the sub-district dispose identical transmission cycle period, thereby had saved overhead.When class of business more when number of users in the sub-district, the user is also many; For example hot zones and Olympic venue area etc.; Can select second configuration mode, be each user's configuration transmission cycle period separately according to each user's in the sub-district the user gradation and the grade of service, thereby improved the SR configuration flexibility; Make full use of limited SR resource, reduce traffic delay.
Particularly, when confirming user's transmission cycle period, user's user gradation is high more in the sub-district, can be short more for this user configured transmission cycle period; In the sub-district in user's the grade of service delay requirement short more, can be short more for this user configured transmission cycle period.
In this step,, adopt different modes to confirm to be used for the sub-frame of uplink of transmitting and scheduling request respectively to FDD system and TDD system.
For the FDD system; Can be with sending all interior sub-frame of uplink of cycle period as the sub-frame of uplink that is used for the transmitting and scheduling request; For example; If the transmission cycle period of SR equals 10ms, all 10 sub-frame of uplink that then comprise in this transmission cycle period can be distributed to the transmission that different users carries out dispatch request with the sub-frame of uplink of these transmitting and scheduling requests all as the sub-frame of uplink that is used for the transmitting and scheduling request; The subframe deviant that then these 10 sub-frame of uplink are corresponding can be the value between the 0-9, need utilize 4 bits to identify this 10 sub-frame of uplink; If the transmission cycle period of SR equals 20ms; All 20 sub-frame of uplink that then comprise in this transmission cycle period are all as the sub-frame of uplink that is used for the transmitting and scheduling request; Can utilize value between the 0-19 as the corresponding subframe deviant of these 20 sub-frame of uplink, need utilize 5 bits to identify.
For the FDD system, can also identify the needed bit number of subframe deviant thereby reduce with sending the interior part sub-frame of uplink of cycle period as the sub-frame of uplink that is used for the transmitting and scheduling request.Preferably; Can be with the sub-frame of uplink that sends every separated preset number of sub frames in the cycle period as the sub-frame of uplink that is used for the transmitting and scheduling request; For example, when the transmission cycle period is 10ms, with whenever choosing in all 10 sub-frame of uplink at a distance from one; As the sub-frame of uplink that is used for the transmitting and scheduling request, then only need 3 bits to identify the subframe deviant of 5 sub-frame of uplink that are used for the transmitting and scheduling request.
For the TDD system, in advance to various possible transmission cycle periods, configuration subframe to be selected in the base station, and correspondence is provided with the subframe position sign; The sub-frame of uplink of transmitting and scheduling request is selected to be used for according to current uplink and downlink timeslot ratio configuration and user's transmission cycle period in the base station in said subframe to be selected.Here, subframe to be selected be in the native system might be used for the sub-frame of uplink of transmitting and scheduling request.
In order to guarantee that UE can have enough chances to send the uplink scheduling request, reserves more resources as far as possible in the transmission cycle period of a SR.A kind of opposite extreme situations is that all sub-frame of uplink all need be reserved the SR resource, is about to all possible sub-frame of uplink all as subframe to be selected.
For example, under different time slot ratios disposed in a frame, all possible sub-frame of uplink was a subframe 2,3,4,7,8,9, if the transmission cycle period of a SR is 10ms, subframe then to be selected and corresponding subframe deviant thereof are:
| Index | The subframe position sign | The subframe deviant |
| 0 | 000 | {2} |
| 1 | 001 | {3} |
| 2 | 010 | {4} |
| 011 | {7} | |
| 4 | 100 | {8} |
| 5 | 110 | {9} |
| 6 | 110 | N/A |
| 7 | 111 | N/A |
Table 1
In last table, the subframe deviant has been enumerated all subframes to be selected, and subframe position is designated the subframe deviant of utilizing 3 bit identification.If the transmission cycle period of SR is 20ms, then the maximum available subframe deviant of UE has 12 kinds, minimum needs 4 bits.If the transmission cycle period of SR prolongs, then bit number needs more.
The base station according to current uplink and downlink timeslot ratio and user's transmission cycle period, selects to be used for the sub-frame of uplink of transmitting and scheduling request according to pre-configured subframe to be selected in subframe to be selected.For example, the transmission cycle period of SR is 10ms, and subframe to be selected is provided with as shown in table 1, then works as uplink and downlink timeslot ratio not simultaneously, in current sub-frame of uplink, selects to be used for the sub-frame of uplink of transmitting and scheduling request.Wherein, sub-frame of uplink that can all are current is all as the sub-frame of uplink that is used for the transmitting and scheduling request.
So far, the step of confirming to be used for the sub-frame of uplink of transmitting and scheduling request in this step finishes.In this step, only confirmed that all can be used as the sub-frame of uplink of transmitting and scheduling request,, need when next confirming resource index, together confirm as for specifically distributing which sub-frame of uplink for each user.
Available dispatch request resource is confirmed in the sub-district, the multiplexing preset dispatch request resource index of different UE, so the resource index of UE and mapping relations of actual physical resource existence.Mapping ruler need consider that the resource index of different UEs can not conflict each other, if a UE does not use resource for a long time simultaneously, this dispatch request resource is releasable.
Specifically carry out through following steps:
Step 204 is selected N resource in the unappropriated dispatch request resource in the sub-district, correspondence is distributed to N user one by one.
During specifically through step 203 and 204 allocation schedule request resource, for each UE is carried out the scheduling resource reasonable distribution, the dispatch request resource index can be expressed as:
δ wherein
SRIBe the subframe deviant of dispatch request, N
ID UEBe ID number of UE, T is the transmission cycle period that UE sends SR, N
SRBe all available SR resources, promptly the resource index of dispatch request is the function of the transmission cycle period of subframe deviant, UE ID, SR, available SR resource sum.
A concrete example is: if all users are 10ms in the cycle of sending; The sub-frame of uplink deviant is 2,3,7,8; The sub-frame of uplink number that then is used for the transmitting and scheduling request is 4, and SR resource sum available in the sub-district is 100, and then each sub-frame of uplink that is used for the transmitting and scheduling request can distribute 25 of SR resources; But 25 of corresponding each subframe distributing user, the corresponding one by one resource index of each UE.
Step 205 is handed down to corresponding user with the transmission cycle period of user's dispatch request, the dispatch request resource of distribution and the sub-frame of uplink correspondence at this dispatch request resource place.
Particularly, when issuing the transmission cycle period, can notify UE through the form of system broadcasts or the mode of high-level signaling.Preferably; When first configuration mode is adopted in the configuration of sending cycle period; Can when second configuration mode is adopted in the configuration of sending cycle period, can notify each UE its corresponding transmission cycle period respectively through the form notice UE of system broadcasts through high-level signaling.And send cycle period and can after step 201, directly carry out, perhaps can in this step, together send with dispatch request resource and subframe deviant.
The concrete mode that issues the dispatch request resource is: for available dispatch request resource in the sub-district corresponding resource index is set in advance; The resource index correspondence that the dispatch request resource of distributing is corresponding is handed down to corresponding user.
Step 206 is not used in preset time gate limit value if distribute to user's dispatch request resource, and the base station discharges this scheduling resource that is not used.
Among the present invention,,, then need discharge this dispatch request resource index if certain user does not use the dispatch request resource index that distributes in preset time gate limit value always for guaranteeing making full use of of SR resource.Particularly, base station dispatch request resource that this dispatch request resource index is corresponding is distributed to other UE as available dispatch request resource in dispatch request configuration next time.
So far, the collocation method flow process of uplink scheduling request finishes in the embodiment of the invention.Visible by above-mentioned flow process; The present invention specifically realized the dispatch request in the LTE system transmission cycle period, subframe position and dispatch request resource configuration and issue; Thereby accomplished the configuration of whole dispatch request; And the different qualities according to FDD system and TDD system has provided implementation.
In addition, in said system, maybe be for the certain user; The base station is disregarded and is divided its allocation schedule request resource into; Then can be when the transmission cycle period be set, this type user's transmission cycle period is set to infinity, is not the purpose of this type user allocation schedule request resource thereby reach.
In the specific embodiment of the invention described above, the sub-frame of uplink at the transmission cycle period of SR and SR resource place is separately expression, and is handed down to UE's.Particularly, send cycle period and confirm the bit number that takies, and correspondence is provided with sign according to concrete transmission cycle period number; The sub-frame of uplink that is used for the transmitting and scheduling request utilizes the subframe position sign to represent, and is independent of and sends cycle period and send to UE.In fact; Also can unite sign with the sub-frame of uplink that is used for the transmitting and scheduling request, and unify to be handed down to UE, like this sending cycle period; After UE receives this and unites sign, can directly confirm to distribute to the sub-frame of uplink that self is used for the transmitting and scheduling request and the transmission cycle period of SR.Below the associating identification means is described, wherein same with the above-mentioned embodiment, still represent to be used for the sub-frame of uplink of transmitting and scheduling request with the subframe deviant.
Uniting when identifying sending cycle period and subframe deviant; Transmission cycle period that can all are optional and these send the subframe deviant combination particularize in the cycle period; And Unified coding is a subframe integrated sign of cycle; When issuing transmission cycle period and subframe deviant, directly subframe integrated sign of cycle is handed down to corresponding user.
Subframe integrated label manner of cycle specifically is set has several kinds:
The simplest mode, exactly that all are optional transmission cycle period is listed, and for example exists 4 kinds to send cycle period, is respectively 5ms, 10ms, 20ms and off, and the off representative cycle is an endless.Then; All subframe deviants in the various transmission cycle periods and its are sent cycle period carry out Unified coding, then there are 5 seed frame offset values in the cycle of 5ms, and there are 10 seed frame offset values in the cycle of 10ms; There are 20 seed frame offset values in the cycle of 20ms; Cycle be off have only a kind of maybe, then 4 kinds send that cycle period sends subframe deviant in the cycle period with these 4 kinds all be combined as 36 kinds, send cycle periods and the subframe deviant is carried out Unified coding to these 36 kinds; Corresponding every kind of combination is provided with subframe integrated sign of cycle, then utilizes 6 bits can represent all 36 kinds of situation.
The shared bit number of subframe integrated sign of cycle is more in the aforesaid way, is to save system resource, can also adopt following manner to simplify the bit number that subframe integrated sign of cycle takies.
Particularly; To the FDD system; Can be with every kind of sub-frame of uplink that sends every separated preset number of sub frames in the cycle period as the sub-frame of uplink that is used for the transmitting and scheduling request; Then the sub-frame of uplink deviant that is used for the transmitting and scheduling request in the various transmission cycle periods and its are sent cycle period and carry out Unified coding, the subframe deviant of the sub-frame of uplink of the corresponding transmitting and scheduling request that is useful on and the combination of sending cycle period, subframe integrated sign of the cycle that is provided with.
Perhaps; To the TDD system, can be directed against various possible transmission cycle periods, configuration subframe to be selected in the base station; Like the situation of describing in the previous embodiment; Then all subframes to be selected in the various transmission cycle periods and its corresponding transmission cycle period are carried out Unified coding, the subframe deviant of corresponding all subframes to be selected and the combination of sending cycle period, subframe integrated sign of the cycle that is provided with.
Certainly, above-mentionedly will send cycle period and the subframe deviant is carried out combined coding, unified subframe integrated label manner of cycle is set only is an example, in practical application, can also adopt other coded system that combined coding is carried out in its combination.
More than being merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
