Embodiment
For making purpose of the present invention, technological means and advantage clearer, the present invention is described in 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 determined the transmission cycle of user's dispatch request and the sub-frame of uplink of transmitting and scheduling request, then, utilize the dispatch request resource sum in the sub-district and the sub-frame of uplink number of transmitting and scheduling request, determine the assignable dispatch request resource of each sub-frame of uplink, the dispatch request resource that to determine again and the concrete sub-frame of uplink at this resource place are distributed to the user, and notify the sub-frame of uplink at user's dispatch request resource, this resource place and the transmission cycle of dispatch request.
Among the present invention during the dispatch request resource of configure user, utilize available dispatch request resource on the transmission cycle 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 of distributing to self in transmission cycle, utilizes 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 determining the transmission cycle of user SR, all users' unifications in the sub-district can be configured to identical transmission cycle, can be each user's configuration transmission cycle separately according to the user gradation and the grade of service of each user in the sub-district also perhaps.For the sub-frame of uplink that is used for the transmitting and scheduling request in the transmission cycle, then can adopt different definite modes according to 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 sub-frame of uplink in transmission cycle the subframe deviant or the information of other unique identification subframes indicate; When issuing transmission cycle, 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 according to base station in the step 103, just can the sub-frame of uplink of appointment in transmission cycle 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.By above-mentioned flow process as seen, the present invention can determine the transmission cycle 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 determine is notified 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.
Below by specific embodiment specific implementation of the present invention is described in further detail.In the present embodiment, utilize the subframe deviant of sub-frame of uplink in transmission cycle to indicate the sub-frame of uplink at dispatch request place, utilize default 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 determining transmission cycle, 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 time delay is little.
In a kind of optional solution, all users' of a sub-district SR transmission cycle is identical, and utilizes the form of system broadcasts to notify the user this transmission cycle.
Simultaneously, consider that the requirement to time delay is different in the business demand of different user in the practical application, the demand of the SR transmission cycle of different user also may be different, therefore SR transmission cycle that can different user 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 transmission cycle certainly will increase overhead.Therefore, need between expense and time delay, obtain a compromise according to the application scenarios of reality.
Among the present invention,, select the configuration mode of transmission cycle particularly, be specially the transmission cycle that the user determines 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 of transmission cycle comprises two kinds: first configuration mode is that all users' unifications in the sub-district are configured to identical transmission cycle; Second configuration mode is, is each user's configuration transmission cycle separately according to the user gradation and the grade of service of each user in the sub-district.
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, 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, the user gradation and the grade of service according to each user in the sub-district are each user's configuration transmission cycle separately, thereby improved the SR configuration flexibility, make full use of limited SR resource, reduce traffic delay.
Particularly, when determining user's transmission cycle, user's user gradation is high more in the sub-district, can be short more for this user configured transmission cycle; 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.
In this step,, be identified for the sub-frame of uplink of transmitting and scheduling request respectively in different ways at FDD system and TDD system.
For the FDD system, can be with all sub-frame of uplink in the transmission cycle as the sub-frame of uplink that is used for the transmitting and scheduling request, for example, if the transmission cycle of SR equals 10ms, then 10 sub-frame of uplink of all that comprise in this transmission cycle are all as the sub-frame of uplink that is used for the transmitting and scheduling request, the sub-frame of uplink of these transmitting and scheduling requests can be distributed to the transmission that different users carries out dispatch request, then the subframe deviant of these 10 sub-frame of uplink correspondences can be the value between the 0-9, need utilize 4 bits to identify this 10 sub-frame of uplink; If the transmission cycle of SR equals 20ms, then 20 sub-frame of uplink of all that comprise in this transmission cycle 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 subframe deviant of these 20 sub-frame of uplink correspondences, need utilize 5 bits to identify.
For the FDD system, can also identify the needed bit number of subframe deviant thereby reduce with the part sub-frame of uplink in the transmission cycle as the sub-frame of uplink that is used for the transmitting and scheduling request.Preferably, can with in the transmission cycle every the sub-frame of uplink of default number of sub frames as the sub-frame of uplink that is used for the transmitting and scheduling request, for example, when transmission cycle is 10ms, to choose every one in all 10 sub-frame of uplink, 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 at various possible transmission cycles, 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 in the base station in described 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 of a SR.A kind of opposite extreme situations is that all sub-frame of uplink all need to reserve 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 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 of SR is 20ms, then the maximum available subframe deviant of UE has 12 kinds, minimum needs 4 bits.If the transmission cycle of SR prolongs, then bit number needs more.
The base station according to current uplink and downlink timeslot ratio and user's transmission cycle, 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 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, selects to be used for the sub-frame of uplink of transmitting and scheduling request in current sub-frame of uplink.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 that is identified for the sub-frame of uplink of transmitting and scheduling request in this step finishes.In this step, only determined that all can be used as the sub-frame of uplink of transmitting and scheduling request,, need when next determining resource index, together determine as for specifically distributing which sub-frame of uplink for each user.
Available dispatch request resource is determined in the sub-district, the multiplexing default 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 mutually, if a UE does not use resource for a long time simultaneously, this dispatch request resource is releasable.
Specifically carry out as follows:
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 by 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 that UE sends SR, N
SRBe all available SR resources, promptly the resource index of dispatch request is the transmission cycle of subframe deviant, UE ID, SR, the function of available SR resource sum.
A concrete example is: if all users send the cycle all is 10ms, 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, SR resource sum available in the sub-district is 100, 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 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 transmission cycle, can notify UE by the form of system broadcasts or the mode of high-level signaling.Preferably, when first configuration mode is adopted in the configuration of transmission cycle, can when second configuration mode is adopted in the configuration of transmission cycle, can notify each UE its corresponding transmission cycle respectively by the form notice UE of system broadcasts by high-level signaling.And transmission cycle can directly be carried out after step 201, perhaps can together send with dispatch request resource and subframe deviant in this step.
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 of the dispatch request resource correspondence of distributing is handed down to corresponding user.
Step 206 is not used in default 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 to discharge this dispatch request resource index if certain user does not use the dispatch request resource index that distributes in default time gate limit value always for guaranteeing making full use of of SR resource.Particularly, other UE as available dispatch request resource, are distributed to the dispatch request resource of this dispatch request resource index correspondence in the base station in dispatch request configuration next time.
So far, the collocation method flow process of uplink scheduling request finishes in the embodiment of the invention.By above-mentioned flow process as seen, specific implementation of the present invention dispatch request in the LTE system transmission cycle, subframe position and dispatch request resource configuration and issue, thereby finished 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, may be for the certain user, the base station is disregarded and is divided its allocation schedule request resource into, then can be when transmission cycle be set, this class user's transmission cycle is set to infinity, is not the purpose of this class 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 of SR and SR resource place is separately expression, and is handed down to UE's.Particularly, transmission cycle is determined the bit number that takies according to concrete transmission cycle number, and correspondence is provided with sign; 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 transmission cycle and sends to UE.In fact, also transmission cycle and the sub-frame of uplink that is used for the transmitting and scheduling request can be united sign, and unify to be handed down to UE, like this, after UE receives this and unites sign, can directly determine to distribute to the sub-frame of uplink that self is used for the transmitting and scheduling request and the transmission cycle 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.
When transmission cycle and subframe deviant are united sign, can be with the combination of the subframe deviant in all optional transmission cycles and these transmission cycles particularize, and Unified coding is a subframe integrated sign of cycle, when issuing transmission cycle and subframe deviant, directly subframe integrated sign of cycle is handed down to corresponding user.
Subframe integrated label manner of cycle specifically is set to be had several:
The simplest mode is listed all optional transmission cycles exactly, for example has 4 kinds of transmission cycles, is respectively 5ms, 10ms, 20ms and off, and the off representative cycle is an endless.Then, all subframe deviants in the various transmission cycles and its transmission cycle are carried out Unified coding, then there are 5 seed frame offset values in the cycle of 5ms, 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 is that off has only a kind of possibility, then all of the subframe deviant in 4 kinds of transmission cycles and these 4 kinds of transmission cycles are combined as 36 kinds, these 36 kinds of transmission cycles and subframe deviant are carried out Unified coding, corresponding every kind of combination is provided with subframe integrated sign of cycle, then utilizes 6 bits can represent all 36 kinds of situations.
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, at the FDD system, can with in every kind of transmission cycle every the sub-frame of uplink of default number of sub frames 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 cycles and its transmission cycle are carried 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 transmission cycle, subframe integrated sign of the cycle that is provided with.
Perhaps, at the TDD system, can be at various possible transmission cycles, configuration subframe to be selected in the base station, the situation of describing among the embodiment as described above, then all subframes to be selected in the various transmission cycles and its corresponding transmission cycle are carried out Unified coding, the subframe deviant of corresponding all subframes to be selected and the combination of transmission cycle, subframe integrated sign of the cycle that is provided with.
Certainly, above-mentioned transmission cycle and subframe deviant are carried out combined coding, unified subframe integrated label manner of cycle is set only is an example, in actual applications, can also adopt other coded system that combined coding is carried out in its combination.
Being preferred embodiment of the present invention only below, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
