Description
Technical field
The present invention relates to mobile communication technology, particularly relate to a kind of method and system of uplink data sending.
Background technology
Long Term Evolution (LTE in third generation partner program (3GPP); Long TermEvolution) after the technology, the 3GPP tissue continues the LTE scheme is strengthened, and this technique for enhancing is called LTE and strengthens (LTE-A; LTE-Advanced) technology, promptly LTE-A is the follow-up evolution of LTE technology.
With respect to version 8 (R8) system; The LTE-A technology is had higher requirement to the delay character of version 10 (R10) system; Be the evolved universal wireless communication interface (E-UTRA that strengthens in the LTE-A specification requirement R10 system; Universal TelecommunicationRadio Access) and the evolution that strengthens whole world terrestrial radio Access Network (E-UTRAN; Universal Terrestrial Radio Access Net) with respect to E-UTRA in the R8 system and E-UTRAN, all to support littler chain of command time delay and user plane time delay.Fig. 1 is the chain of command time delay figure in the desired R10 of the LTE-A technology system.As shown in Figure 1; The LTE-A technology to the requirement of chain of command time delay in the R10 system is: the object transmission time between idle pulley (comprising the distribution of IP address) and the connection mode is less than 50 milliseconds; This process comprises the foundation of user plane, but does not comprise the propagation delay time of S1 interface; And under connection mode, the object transmission time between resting state and the state of activation does not comprise discontinuous reception (DRX, Discontinuous Reception) time delay less than 10 milliseconds in this process.And for user plane time delay; Do not stipulate concrete delay volume as yet in the LTE-A technology at present; But require user plane especially to note reducing time delay in following two kinds of situation, make it littler than the corresponding delay volume in the R8 system, both of these case is: (1) subscriber equipment (UE) does not have the efficient scheduling Resources allocation; (2) UE need carry out synchronous and obtain scheduling resource.
For realizing the above-mentioned requirements of LTE-A technology to R10 system delay character, prior art has adopted the up send mode based on competition (CB, Contention Based).Fig. 2 utilizes the flow chart of the CB resource uplink data sending of evolution base station (eNode B) mandate for UE in the prior art.As shown in Figure 2, this flow process may further comprise the steps:
Step 201: to different UE groups; ENode B divides into groups to available CB resource accordingly; Make between UE group and the CB resource group and have one-to-one relationship; And organize transmission respectively to each UE and organize the corresponding Radio Network Temporary Identifier (CB-RNTI, Contention Based-Radio Network Tempory Identifier) based on competition with this UE, after each UE winding receives that eNode B sends to the CB-RNTI of self; Monitor the authorization message whether self corresponding CB resource group is arranged on the Physical Downlink Control Channel (PDCCH, physical downlink control channel).
Here, after prior art is divided into groups to the UE in the same sub-district, promptly obtain a plurality of UE groups, have relation one to one between UE group and the CB-RNTI.CB-RNTI is used to notify self corresponding UE group to monitor whether to have on the PDCCH self authorization message of corresponding CB resource group, if having, then the UE in this UE group just can use the CB resource in the CB resource group of having passed through mandate, uplink data sending.
Step 202: to each UE group, eNode B takies the authorization message that a PDCCH distributes the CB resource group corresponding with this UE group.
Here, the authorization message of the CB resource group corresponding with the UE group is used for authorizing the UE of this UE group to utilize the CB resource uplink data sending in this CB resource group.
Step 203: after each UE group listens to the authorization message of self corresponding CB resource group from PDCCH, utilize the CB resource uplink data sending in self corresponding CB resource group.
In flow process shown in Figure 2, the eNode B of R10 system initiatively distributes the authorization message of the corresponding CB resource group of each UE group, after each UE group listens to the authorization message of self corresponding CB resource group; Need the UE of uplink data sending from the corresponding CB resource group of this UE group, to select the CB resource to carry out up transmission voluntarily; This shows, send dispatch request (SR by UE to eNode B earlier for avoiding competition (CF, Contention Free) with respect to the R8 system; Scheduling Request) thus obtain the method for the resource that eNode B distributes; The step of R10 system assignment resource has obtained simplifying, thereby has reduced time delay effectively, has also reduced signaling consumption.
But in the prior art, because UE in the sub-district and available CB resource are divided into many groups, eNode B need send respectively and the corresponding CB-RNTI of this UE group to each UE group, thereby system need reserve the demand that a plurality of CB-RNTI satisfy uplink data sending.In addition; In the prior art, to each UE group, eNode B need take the authorization message that a PDCCH distributes the CB resource group corresponding with this UE group; Thereby prior art need take the authorization message that many PDC CH distribute CB resource group; The use amount of PDCCH is bigger, and PDCCH is a kind of scarce resource, and prior art takies the waste that way that many PDCCH distribute CB resource group authorization message has caused the PDCCH resource.

Like this, in the present invention, because eNode B only needs to send same CB-RNTI to each UE; Can realize the purpose of notifying all UE that the authorization message whether the CB resource is arranged on the PDCCH is monitored; Therefore, the present invention only need use a CB-RNTI to get final product, and this has practiced thrift CB-RNTI effectively.In addition; Among the present invention because eNode B has sent the grouping number m of CB resource when sending CB resource authorization information to each UE; By authorization message and the grouping number m of each UE, be about to the CB resource certainly and be divided into m group, and from m group CB resource group, choose the CB resource group of self appointment according to the CB resource; And then utilize the CB resource in the CB resource group of self appointment to realize uplink data sending; Therefore, eNode B only need take the authorization message that a PDCCH sends one group of CB resource and gets final product among the present invention, thereby has greatly practiced thrift the PDCCH resource.
In order to make the object of the invention, technical scheme and advantage clearer, describe the present invention below in conjunction with accompanying drawing and specific embodiment.
Fig. 3 utilizes the flow chart of the CB resource uplink data sending of eNode B mandate for UE provided by the invention.As shown in Figure 3, the present invention proposes a kind of method of uplink data sending, this method may further comprise the steps:
Step 301:eNode B sends same CB-RNTI to each UE, is used to notify each UE to monitor whether the authorization message of CB resource is arranged on the PDCCH, and the authorization message of said CB resource is used for the CB resource authorization is used to UE; After each UE receives said CB-RNTI, monitor the authorization message whether the CB resource is arranged on the PDCCH.
UE described here is the UE that is arranged in same sub-district and need carries out up transmission, does not need the UE of uplink data sending can not receive CB-RNTI and the authorization message of monitoring CB resource group in the sub-district.
ENode B sends to the mode of each UE with CB-RNTI, can be that broadcasting is sent, and also can send for utilizing dedicated signaling.
Here; Because eNode B only needs to send same CB-RNTI to each UE, can realize the purpose of notifying all UE that the authorization message whether the CB resource is arranged on the PDCCH is monitored, therefore; The present invention only need use a CB-RNTI to get final product, and this has practiced thrift CB-RNTI effectively.
Step 302:eNode B takies a PDCCH, sends the authorization message and the grouping number m of CB resource of CB resource to each UE, and the span of said m is for greater than 0 and be not more than the total integer of CB resource.
Step 303: each UE receives the grouping number m of authorization message and CB resource of said CB resource from PDCCH after; Grouping number m according to the authorization message and the CB resource of said CB resource; The CB resource that will be authorized to use is divided into m CB resource group, and from said m CB resource group, selects a CB resource group as self appointment.
Here, after UE receives the authorization message of CB resource, just can confirm to pass through the scope of the CB resource that eNode B authorizes, and then, these CB resources have been divided into m CB resource group according to the grouping number m of CB resource.
Step 304: each UE utilizes the CB resource in the CB resource group of self appointment, to eNode B uplink data sending.
Here, each UE at first handled the data of the up transmission of needs before utilizing CB resource uplink data sending; These processing comprise modulation, encode, add packet header etc.; Obtain protocol Data Unit (PDU, Protocol Data Unit) after disposing, each UE selects the CB resource that PDU is carried out up transmission from the CB resource group of self appointment then; The CB resource comprises Physical Uplink Shared Channel (PUSCH, Physical Uplink SharedCHannel).
For ease of eNode B the UE of up transmission PDU is discerned; Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (the C-RNTI that comprises this UE among the PDU that each UE sent; Cell-RadioNetwork Tempory Identifier); Owing to have relation one to one between the UE of same sub-district and the C-RNTI, therefore, eNode B can identify the UE that sends upstream data according to C-RNTI.
Because eNode B has sent the grouping number m of CB resource in the step 302 when sending CB resource authorization information to each UE; In step 303, be divided into m group from being about to the CB resource by each UE; And from m group CB resource group, choose the CB resource group of self appointment; And then in step 304, utilize the CB resource in the CB resource group of self appointment to realize uplink data sending; Therefore, eNode B only need take the authorization message that a PDCCH sends one group of CB resource and gets final product among the present invention, thereby has greatly practiced thrift the PDCCH resource.
In step 303, each UE is according to the grouping number m of the authorization message and the CB resource of CB resource, and the CB resource that will be authorized to is divided into m CB resource group, and the method for grouping is:
Each UE is according to the authorization message of CB resource, the total k of the CB resource of confirming to be authorized to use;
Each UE calculates the number n um of CB resource in each CB resource group according to num=ceil (k/m), and wherein, ceil (k/m) computing is for obtaining being not less than the smallest positive integral of real number (k/m);
Each UE is according to the authorization message of CB resource; Confirm the starting point of first CB resource as number one CB resource group; And begin from first CB resource; With the CB resource of the every increase of sequence number (num-1) terminal point, with the CB resource of the every increase of sequence number num starting point, until the terminal point of confirming (m-1) number resource group and the starting point of m resource group as next CB resource group as this CB resource group; With the terminal point of k CB resource, then starting point, terminal point and starting point and the CB resource between the terminal point of each CB resource group are confirmed as the CB resource in the same CB resource group then as m resource group;
So far, the UE CB resource that will the be authorized to process that is divided into m CB resource group finishes.
This method specifically is exemplified below:
In the authorization message of the CB resource that eNode B sends, that authorizes CB resource that UE uses adds up to 8, is respectively A, B, C, D, E, F, G, H, and the grouping number m=3 of the eNode B CB resource of sending, then
At first, each UE is according to the authorization message of CB resource, the total k=8 of the CB resource of confirming to be authorized to use;
Secondly, each UE calculates the number n um of CB resource in each CB resource group according to num=ceil (k/m), through computing, and num=3, then (num-1)=2;
Once more, each UE confirms the starting point of first CB resource A as number one CB resource group according to the authorization message of CB resource; And begin from first CB resource A, with the CB resource of the every increase by 2 of sequence number terminal point, with the CB resource of the every increase by 3 of sequence number starting point as next CB resource group as this CB resource group; Until the terminal point of confirming No. second resource group and the starting point of No. three resource group, then with the terminal point of the 8th CB resource, like this as No. three resource group; The starting point of first, second and third number CB resource group is respectively A, D, G; Terminal point is respectively C, F, H, and like this, determined three CB resource groups are as shown in table 1:
| Number one CB resource group | No. second CB resource group | No. three CB resource group |
| A、B、C | D、E、F | G、H |
Table 1
So far, the UE CB resource that will the be authorized to process that is divided into 3 CB resource groups finishes.
In step 303, each UE selected a CB resource group as self appointment from said m CB resource group before, this method further comprised: confirm a parameter a who has one-to-one relationship with UE;
Like this; Each UE selects a method as the CB resource group of self appointment to be from said m CB resource group: each UE is according to group=a mod m; Calculate the sequence number group of the CB resource group of said self appointment; Wherein, to be parameter a ask modular arithmetic to the grouping number m of CB resource in (a mod m) computing.
Like this, corresponding with parameter a UE just can be with the CB resource group of (a mod m) group CB resource group as self appointment.
About the selection of parameter a, can be divided into following two kinds of situation:
First kind of situation:
When UE has disposed specific schedule request (D-SR; Dedicated-SchedulingRequest) during resource; Parameter a can select the dispatch request physical uplink control channel resource index (SR-PUCCH-Resource Index) in the D-SR configuration information, or the dispatch request configuration index in the D-SR configuration information (SR-Config Index).All UE confirm that the mode of parameter a is identical; That is to say; When having disposed the D-SR resource, all UE confirm that simultaneously SR-PUCCH-Resource Index is as parameter a, perhaps; All UE confirm SR-Config Index simultaneously as parameter a, and this can guarantee the uniformity that each UE divides into groups to the CB resource.
Here; Comprise these two parameters of SR-PUCCH-Resource Index and SR-Config Index in the D-SR configuration information; These two all round numbers of parameter; Such as, the span of SR-PUCCH-Resource Index can be the arbitrary integer between 0 to 2047, the span of SR-Config Index can be the arbitrary integer between 0 to 157.Certainly, these two parameter range of SR-PUCCH-Resource Index and SR-Config Index also can be other scopes.
When UE does not dispose the D-SR resource; UE does not just have the D-SR configuration information; Thereby can not select SR-PUCCH-Resource Index or SR-Config Index as parameter a; At this moment, UE does not adopt and utilizes parameter a to ask the mode of modular arithmetic to find the CB resource group of self appointment to the grouping number m of CB resource, but adopts one of following two kinds of methods to confirm the CB resource group of self appointment:
Method one: UE is an optional CB resource group as self appointment from said m CB resource group;
Method two: eNode B further sends no D-SR resource group indication information to each UE, the CB resource group of the UE use that is used to indicate confession not dispose the D-SR resource; After the UE that does not dispose the D-SR resource received no D-SR resource group indication information, the CB resource group that no D-SR resource group indication information is indicated was as the CB resource group of self appointment.
Second kind of situation:
Parameter a selects C-RNTI for use.
Because all UE have C-RNTI, and have relation one to one between the UE of same sub-district and the C-RNTI, therefore, select for use C-RNTI, can distinguish UE and whether dispose the D-SR resource as parameter a.
The present invention also provides a kind of system of uplink data sending, and Fig. 4 is the system diagram of uplink data sending provided by the invention.As shown in Figure 4, this system comprises: evolution base station 401 and a plurality of subscriber equipmenies 402, wherein,
Each subscriber equipment 402 is used for after receiving said CB-RNTI, monitors the authorization message whether the CB resource is arranged on the PDCCH; Receive the grouping number m of authorization message and CB resource of said CB resource from PDCCH after; Grouping number m according to the authorization message and the CB resource of said CB resource; The CB resource that will be authorized to use is divided into m CB resource group, and from said m CB resource group, selects a CB resource group as self appointment; Utilize the CB resource in the CB resource group of self appointment, to evolution base station 401 uplink data sendings.
Because 401 need of evolution base station send same CB-RNTI to each subscriber equipment 402; The purpose that whether can realize notifying has the CB resource on 402 couples of PDCCH of all subscriber equipmenies authorization message is monitored; Therefore; This system only need use a CB-RNTI to get final product, and this has practiced thrift CB-RNTI effectively.In addition; In the native system since evolution base station 401 at the grouping number m that when each subscriber equipment 402 sends CB resource authorization information, has sent the CB resource; By authorization message and the grouping number m of each subscriber equipment 402, be about to the CB resource certainly and be divided into m group, and from m group CB resource group, choose the CB resource group of self appointment according to the CB resource; And then utilize the CB resource in the CB resource group of self appointment to realize uplink data sending; Therefore, 401 need of evolution base station take the authorization message that a PDCCH sends one group of CB resource and get final product in the native system, thereby have greatly practiced thrift the PDCCH resource.
