Description
Technical field
The present invention relates to the communications field, particularly a kind of scheduling of resource indication and processing method and device.
Background technology
To LTE and LTE-A system; Define in the relevant criterion such as 3GPP TS36.211/212/213; PDCCH (descending control physical channel) is used to carry the dispatch of uplink/downlink sub-carriers channel; Be Uplink grant/Downlink grant, and defined relevant signaling information form to different transmission modes.Simultaneously, also defined the correlation timing relation, be specially: consult illustrated in figures 1 and 2, when scheduling downlink resource, the PDSCH (downlink business physical channel) of this subframe of each PDCCH scheduling; During ascending resource scheduling, need to keep UE (subscriber equipment) and detect the control signaling and prepare the processing delay of up channel transmission, for example; For the FDD system, the definition time delay is 3ms (assert that usually the transmission time that a sub-frame takies is 1ms), promptly at n+4 subframe transmission PUSCH (uplink service physical channel); And for the TDD system, because receive the influence of uplink and downlink timeslot ratio, the definition time delay is (k; K＞=3) ms; Promptly at n+k subframe transmission PUSCH (uplink service physical channel), concrete k value is relevant with time slot ratio, and the definition mode of k can be as shown in table 1:
Table 1
Under the prior art, the scheduling of resource mode that system adopts mainly contains two kinds, is respectively dynamic resource scheduling and semi-continuous scheduling of resource:
So-called dynamic resource scheduling; Be meant that promptly the base station passes through a dispatch grant (scheduling) data transfer (on TDD/the downstream arrangements 0); And use exclusive C-RNTI (the Cell-RadioNetwork Temporary Identity of UE; Cell Radio Network Temporary Identifier/Identity, Cell-RNTI) CRC in this dispatch (Cyclic Redundancy Check, CRC) is carried out scrambling.For a UE, a DL grant and/or a UL grant can only be arranged in each descending sub frame, as, the DL grant among the descending sub frame n is used for dispatching the downlink data transmission of this subframe; And for example; For the FDD system; UL grant among the descending sub frame n is used for the transmitting uplink data of dispatching uplink subframe n+4, for the TDD system, to last/downstream arrangements 1～6; UL grant among the descending sub frame n is used for the transmitting uplink data of dispatching uplink subframe n+k, and wherein the value of k is as shown in table 1; To uplink-downlink configuration 0, if the MSB (highest significant position) in UL index (indication) information among the UL grant of descending sub frame n is 1, then this UL grant is used for the transmitting uplink data of dispatching uplink subframe n+k, and wherein k is as shown in table 1; If the LSB (least significant bit) in the UL index information is 1, then this UL grant is used for the transmitting uplink data of dispatching uplink subframe n+7; If MSB and LSB are 1, then this UL grant is used for the transmitting uplink data of dispatching uplink subframe n+k and n+7.Wherein, a plurality of radio frames sequence arrangement, even last subframe is k among the radio frames a; Then first subframe is k+1 among the radio frames a+1; Table 1 with a radio frames be example provided each sub-frame of uplink for the situation of k, wherein n+k＞9, the then sub-frame of uplink in one radio frames of expression back.
So-called semi-continuous scheduling of resource; The system that promptly is meant at first disposes the cycle parameter of semi-continuous scheduling through high-level signaling; Trigger relevant UL/DL scheduling of resource through dispatch again, effective duration of each UL/DL scheduling of resource that triggers is carried out according to pre-configured cycle parameter, for example; If cycle parameter is configured to 20ms, then UE assert that the each indicated scheduling of resource mode term of validity of dispatch of sending of system is 20ms; Wherein, The concrete indicating mode of dispatch can be with reference to the dispatch indicating mode under the dynamic resource scheduling, and different is, under the dynamic resource scheduling; Go up each time/downlink data transmission all need send a dispatch and dispatch; And in semi-continuous scheduling, dispatch of the every transmission of system, in can the indicative of settings cycle on/downlink data transmission.Under semi-continuous scheduling of resource, the DCI that carries in the dispatch (Downlink Control Information) carries out scrambling through SPS-RNTI (Radio Network Temporary Identifier of semi-continuous scheduling); On/downlink data transmission carries out according to transformat of formulating in the standard and resource location, up to receiving SPS (semi-continuous scheduling) resource release signaling, a SPS finishing scheduling.
Under the prior art, dynamic resource scheduling is applicable to transfer of data flexibly, and shortcoming is that the expense of dispatch is bigger, therefore, relatively be applicable to/business that the downlink data transmission amount is bigger because this moment dispatch expense just relatively meet expectation; And semi-continuous scheduling is applicable to stable business, and for example, voice service (VoIP) is because this type of business has periodicity and stability preferably.
But along with the enhancing of mobile radio system, the type of service of support is also more and more abundanter, for example M2M (machine to machine; Machine), new business possibility data amount transmitted is less, but stablizes longer duration periodically again be not as professional as VoIP; At this moment, if use the dynamic resource scheduling mode, then can cause the expense of dispatch excessive; To bring operating load to system; And use the SPS scheduling mode to need the frequent resource of carrying out to trigger and release, and also will cause the expense of dispatch excessive, can bring operating load to system equally.
In view of this, need design a kind of new scheduling of resource indicating mode again.

Embodiment
Less and the unabiding novel business of cycle to data amount transmitted (as; M2M is professional); The signaling consumption that produces when reducing scheduling of resource; In the embodiment of the invention, designed a kind of new scheduling of resource indicating means again: be specially: network side adopts high-level signaling configuration associated transport patten (pattern) and sends to UE, adopts dispatch to dispatch triggering again; Compared to the dynamic resource scheduling mode, the scheduling mode that the embodiment of the invention provides is to carry out scheduling of resource according to transmission patten, can once dispatch a plurality of subframe data packets for transmission; Further, compared to SPS scheduling of resource mode, fix the effective time of scheduling mode provided by the invention, need not carry out resource and discharge, and surpasses the effective time of higher level parameters configuration, and resource can discharge automatically.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
Consult shown in Figure 3ly, in the embodiment of the invention, network side apparatus (like, base station) comprises first communication unit 30 and second communication unit 31, wherein,
First communication unit 30 is used for sending pre-configured transmission patten to UE, and this transmission patten is used for carrying at least two of UE indications the relative position of the subframe of transmission data;
Second communication unit 31 is used for sending dispatch at descending sub frame n to said UE, and indication UE is based on the transmission patten of descending sub frame n and acquisition, in the transfer of data of at least two sub-frame execution accordingly.
Based on technique scheme, to consult shown in Figure 4ly, in the embodiment of the invention, it is following that network side carries out the detailed process of scheduling of resource indication:
Step 400: network side sends pre-configured transmission patten to UE, and this transmission patten is used for carrying at least two of UE indications the relative position of the subframe of transmission data.
For example, suppose to comprise among the transmission pattern of network side configuration the relevant information of 10 sub-frame, promptly transmitting maximum length is 10; Then consult shown in Figure 5, in the embodiment of the invention, network side through high-level signaling (like, RRC (Radio Resource Control; Radio resource control) signaling) the transmission patten of configuration is: and 0,1,6,7}; Promptly be illustrated in relative position and be on 0,1,6 and 7 the subframe and have transfer of data, so-called transfer of data is as far as UE; Can be the Data Receiving on the descending sub frame, also can be that the data on the sub-frame of uplink are sent, and this point will describe in detail in the subsequent implementation example.
In the present embodiment, network side sends pre-configured transmission patten to UE, can adopt in the following mode any one, but be not limited only to following implementation:
A, network side adopt Bitmap (bit map) mode to UE notification transmission pattern through high-level signaling.
For example, be that { 0,1,6,7} is an example, adopts the Bitmap mode so when UE notification transmission pattern, and network side can be { 1100001100} to the selected subframe of UE indication still with pre-configured transmission patten;
B, network side are shown relative sequence number mode clearly through the high-level signaling employing and are notified pre-configured transmission pattern to UE.
For example, be that { 0,1,6,7} is an example still with pre-configured transmission patten; So, adopt and show relative sequence number mode clearly when UE notification transmission pattern, network side can be { 0,1,6 to the selected subframe of UE indication; 7, NA, NA, NA, NA; NA, NA}, NA represent non-selected subframe, can be defined as a certain particular values;
Again for example, be { 0,1,6 still with pre-configured transmission patten; 7} is an example, so, adopts and shows relative sequence number mode clearly when UE notification transmission pattern, and network side can also be { 0 to the selected subframe of UE indication; 1,6,7; #}, # represent that indication finishes, and can be defined as a certain particular values or content.
Step 410: network side sends dispatch at descending sub frame n to UE, and indication UE is based on the transmission patten of descending sub frame n and acquisition, in the transfer of data of at least two sub-frame execution accordingly.
In the present embodiment, network side is that the PDCCH through descending sub frame n sends dispatch to UE, the DCI that this dispatch carries by network side adopt can unique identification UE identification information carry out scrambling.Consult shown in Figure 6; According to correlation standard, the PDCCH of transmitting and scheduling signaling only can be carried on descending sub frame n before on several OFDM (Orthogonal Frequency Division Multiplexing, OFDM) symbol; Other OFDM symbols are used to carry the business datum that PDSCH (Physical Downlink Shared Channel) goes up transmission; The concrete resource location of business data transmission, promptly the particular location of PRB (Physical Resource Block) is issued a separate notice by high-level signaling, repeats no more at this.
In the above-described embodiments, be example (TDD system reference FDD system carries out corresponding configuration and gets final product) with the FDD system, the concrete executive mode of step 410 is following:
If what network side sent to UE at descending sub frame n is the descending scheduling signaling; Then network side indication UE is based on the transmission patten of descending sub frame n and acquisition; Confirm that network side carries out at least two descending sub frames of downlink data transmission, and on these at least two descending sub frames, receive the downlink data of network side transmission.
For example, consult shown in Figure 7ly, the transmission pattern of supposing the system configuration is { 0,1; 6,7} is the descending scheduling signaling and network side sends to UE at the PUCCH of descending sub frame n, and then UE is according to descending sub frame n that receives the descending scheduling signaling and transmission pattern{0; 1,6,7}, confirm network side carry out downlink data transmission descending sub frame be numbered { n+0; N+1, n+6, n+7}; Then UE will be at descending sub frame n+0, and descending sub frame n+1, descending sub frame n+6 and descending sub frame n+7 go up and receive the downlink data that network side sends.
And be the uplink scheduling signaling if network side sends to UE at descending sub frame n; Then network side indication UE is based on the transmission patten of descending sub frame n and acquisition; With reference to preset time delay; Confirm that UE carries out at least two descending sub frames of transmitting uplink data, and on these at least two sub-frame of uplink, send upstream data to network side.
For example, consult shown in Figure 8ly, the transmission pattern of supposing the system configuration is { 0,1,6; 7} is the uplink scheduling signaling and network side sends to UE at the PUCCH of descending sub frame n, and then UE is according to descending sub frame n that receives the uplink scheduling signaling and transmission pattern{0,1; 6,7} handles the required preset time delay k of uplink scheduling signaling with reference to UE, supposes k=3ms; Promptly postpone 3 sub-frame, confirm { n+4+0, n+4+1, the n+4+6 of being numbered to the sub-frame of uplink of network side transmit ascending data; N+4+7}, then UE will be at sub-frame of uplink n+4+0, sub-frame of uplink n+4+1, sub-frame of uplink n+4+6 and sub-frame of uplink n+4+7 go up to network side and send upstream data.
On the other hand, preferable in the above-described embodiments, after the network side execution in step 410, when arrive in preset effective time, discharge the running time-frequency resource (being PUSCH or PDSCH resource) that is used to carry out business data transmission automatically.Send corresponding dispatch and wait for next opportunity to UE.
Based on the foregoing description; In the present embodiment, the Downlink Control Information DCI that network side carries in the dispatch that UE sends at descending sub frame n, employing can be carried out scrambling by unique identification information of discerning UE; Wherein, this identification information configuration mode that can adopt comprises but is not limited to following several kinds:
1) reuse existing C-RNTI (identification information that dynamic resource scheduling uses down), perhaps SPS-RNTI (identification information that uses under the semi-continuous scheduling of resource) is as above-mentioned identification information.
Employing mode 1) during configuration identifier information; Owing to be to reuse existing identification information; Therefore the multiframe scheduling of resource mode that provides of the embodiment of the invention can not be launched with dynamic resource scheduling mode and semi-continuous scheduling of resource mode, simultaneously when system start-up dynamic resource scheduling mode and semi-continuous scheduling of resource mode; The multiframe scheduling of resource mode that the embodiment of the invention of should stopping using automatically provides to avoid the situation that identification information is obscured.
2) the wireless netting twine temporary mark RNTI that uses redetermination is as above-mentioned identification information.
Employing mode 2) during configuration identifier information; Owing to be the identification information that adopts redetermination; The situation that identification information is obscured can not take place; Therefore the multiframe scheduling of resource mode that provides of the embodiment of the invention, or/and semi-continuous scheduling of resource mode can be launched simultaneously, promptly network side can adopt multiple scheduling of resource mode to carry out combined dispatching with the dynamic resource scheduling mode.
3) reuse existing C-RNTI or SPS-RNTI as above-mentioned identification information, and the definition special field is distinguished mutually with existing occupation mode in DCI.
Employing mode 2) during configuration identifier information; Though be to reuse existing identification information; Distinguish but be provided with special field and the existing occupation mode claimed, thereby the situation that identification information is obscured can not take place, so the multiframe scheduling of resource mode that provides of the embodiment of the invention; Or/and semi-continuous scheduling of resource mode can be launched simultaneously, promptly network side can adopt multiple scheduling of resource mode to carry out combined dispatching with the dynamic resource scheduling mode.
Consult Fig. 7 and shown in Figure 8, in the embodiment of the invention, the transfer of data of a plurality of subframes is triggered by a dispatch; Thereby effectively saved the overhead that produces when system carries out scheduling of resource, reduced system loading, further; After arriving effective time, system carries out the release of running time-frequency resource automatically, and need not to wait for release signaling; Therefore, further save overhead, reduced system loading.Wherein, the transfer of data of a plurality of subframes that trigger by dispatch, the PRB position that the modulation demodulation system of its data and transmission are used is identical.
In the practical application; In order to improve the scheduling of resource ability of system; Further, the permission system uses enhancement mode scheduling of resource mode, so-called enhancement mode scheduling of resource mode; Promptly be that to allow to carry out continuously the PRB position of data modem mode and transmission data of a plurality of subframes of transfer of data inequality, promptly allow to issue multiple dispatch and carry out the federated resource scheduling.Be specially: network side at descending sub frame n before UE sends dispatch; Perhaps; At descending sub frame n after said UE sends dispatch; Send other dispatchs at other descending sub frames to UE, carrying out the federated resource scheduling, so-called other dispatchs can be a kind of or combination in any in the dispatch of dispatch and semi-continuous scheduling of resource of dispatch, dynamic resource scheduling of the multiframe scheduling of resource that provides of the embodiment of the invention.
For example, multiframe scheduling of resource mode that the embodiment of the invention is provided and dynamic resource scheduling mode are united when using, and its concrete combined dispatching mode is as shown in Figure 9; The transmission patten that supposing the system issues is { 0,1,6; 7}, system issues the dispatch that is used for the multiframe scheduling of resource at descending sub frame n to UE, and UE is at descending sub frame { n+0 in indication; N+1, n+6, the last downlink data receiving of n+7}; Simultaneously, system issues the dispatch that is used for dynamic resource scheduling at descending sub frame n+3 to UE, indication UE downlink data receiving on descending sub frame n+ 3.
Again for example, the many groups of the multiframe scheduling of resource mode that the embodiment of the invention is provided are united when using, and unite with two groups to be used for example, and its concrete combined dispatching mode is shown in figure 10; Two groups of transmission patten that supposing the system issues are respectively { 0,6, } and { 1,7; 8}, system issues the dispatch 1 that is used for the multiframe scheduling of resource at descending sub frame n to UE, and UE is at descending sub frame { n+0 in indication; The last downlink data receiving of n+6}, simultaneously, system issues the dispatch 2 that is used for the multiframe scheduling of resource at descending sub frame n+1 to UE; UE is at descending sub frame { n+1, n+7, the last downlink data receiving of n+7} in indication.
In sum, in the embodiment of the invention, to novel business demand; Designed new multiframe scheduling of resource mode, promptly, sent dispatch to UE more in advance to the transmission patten of UE notice configuration; Make UE combine the transmission patten that obtains, once realize the transfer of data on a plurality of subframes of scheduling, like this; Can save effectively and send the overhead that dispatch causes, reduce system's operating load, thereby improved systematic function.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
