Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Embodiment one
With reference to Fig. 3, show the flow chart of steps according to a kind of radio frames processing method of the embodiment of the present invention one.
The radio frames processing method of the present embodiment comprises the following steps:
Step S102: node is determined the SFN(System Frame Number of radio frames, System Frame Number when getting radio frames) divide the cycle to carry out the delivery frame number that obtains after modulo operation to frame.
Wherein, described node comprises base station and a plurality of via nodes that are connected successively with the base station.
Node can adopt suitable method arbitrarily when determining the delivery frame number of radio frames, as the method for SFN mould 2 or mould 4 or mould 8, as, after node receives the 5th frame (being SFN=5), calculate 5MOD4=1, determine that the delivery frame number of this frame is 1.
Step S104: node carries out corresponding radio frames and processes according to the state of this pre-configured node at the delivery frame number of determining.
Wherein, the state of base station comprises scheduling next-hop node or UE(User Equipment, subscriber equipment) state and only dispatch the state of UE; In a plurality of via nodes with the base station adjacent and for the state of the via node of most end tail node comprise receive upper hop node data or upper hop node send data state, scheduling next-hop node or UE state and only dispatch the state of UE; In a plurality of via nodes, the state of the via node at end comprises and receives state, the state of only dispatching UE and the down state that upper hop node data or upper hop node send data; The state of other via node in a plurality of via nodes comprises state, scheduling next-hop node or the state of UE, the state of only dispatching UE and the down state that receives upper hop node data or upper hop node transmission data.When a node when the state of a delivery frame number is configured to receive upper hop node data or upper hop node and sends the state of data, the upper hop node of this node is configured to dispatch the state of next-hop node or UE at the state of this delivery frame number, the next-hop node of this node is configured down state at the state of this delivery frame number.
Pass through the present embodiment, a kind of data transmission scheme of multi-hop relay is provided, in including the system of a plurality of via nodes, the state of each node of processing by pre-configured participation radio frames, make each node after receiving radio frames, divide the cycle to carry out the delivery frame number that obtains after modulo operation and pre-configured this node at the state of this delivery frame number according to the SFN of this radio frames to frame, can carry out the processing of corresponding radio frames.In existing trunking plan, the radio frames configuration of a plurality of via nodes is not provided and processes, therefore can't realize the transfer of data of multi-hop relay, and pass through the present embodiment, efficiently solve the problem of the transfer of data of multi-hop relay, reached the effect of the data normal transmission of the system that includes a plurality of via nodes.
Embodiment two
With reference to Fig. 4, show the flow chart of steps according to a kind of radio frames processing method of the embodiment of the present invention two.
In the present embodiment, take the LTE-A system that introduces four via nodes as example, Fig. 5 is the structural representation of this system, as can be seen from Figure 5, base station DeNB is connected successively with four via node RN1, RN2, RN3, RN4, and the node RN 4 at end is connected with terminal R-UE.In addition, although not shown, be connected with corresponding UE under each node of DeN, RN1, RN2, RN3 and RN4.Need to prove, the present embodiment is take the LTE-A system as example, but is not limited to this, other multihop relay system is applicable too, and in the present embodiment, the number of via node is only also exemplary illustration, and the via node of other quantity all can adapt to reference to the present embodiment to be processed.
Based on said structure, the radio frames processing method of the present embodiment comprises the following steps:
Step S202: pre-configured each node is at the state of corresponding delivery frame number.
In the present embodiment, pre-configured base station and four via nodes are at the state of corresponding delivery frame number.The SFN that the delivery frame number refers to radio frames divides the cycle to carry out the frame number that obtains after modulo operation to frame.
Wherein, the residing possible state of each node is described as: the DeNB(base-station node): scheduling sublayer node RN 1(is the next-hop node of DeNB) or UE, UE only dispatched; RN1(and base station are adjacent and be not the via node of most end tail node): receiving DeNB(is the upper hop node of RN1) data or send data to DeNB, scheduling sublayer node RN 2(is the next-hop node of RN1) or UE, only dispatch UE; RN2: receive RN1 data (being the upper hop node of RN2) or send data to RN1, scheduling sublayer node RN 3(is the next-hop node of RN2) or UE, only dispatch UE, unavailable (when RN1 sends or during receive data to DeNB, due to RN2 in the jumping scope of RN1, so RN2 is unavailable); RN3: receive RN2 data (the upper hop node of RN3) or send data, the next-hop node of scheduling sublayer node RN 4(RN3 to RN2) or UE, only dispatch UE, unavailable; The via node at the end of RN4(): receive RN3 data (the upper hop node of RN4) or send data to RN3, only dispatch UE, unavailable.
When a certain frame was configured to the Backhaul subframe, the father node of this node (being even higher level of node) was in the state of scheduling sublayer node or UE when certain node, and the child node of this node (being the next stage node) is unavailable." scheduling UE " refers to dispatch the UE of this RN or DeNB service.
Based on above-mentioned analysis, a RN has at most 4 kinds of states, and the mode that therefore can adopt 4 times of frames to divide for the node less than 4 kinds of states, can reach 4 times of frames by the subframe that configures a plurality of scheduling UE and divide.Certainly, be not limited to this, other multiple level frame of 4 divides also applicable, grades as 8 times of frames.
Below, take the system that contains 2 ~ 6 RN as example, to the examples of configurations of radio frames as following table 1 to as shown in table 5:
Table 1 contains the radio frames configuration of 2 RN
Table 2 contains the radio frames configuration of 3 RN
Table 3 contains the radio frames configuration of 4 RN
Table 4 contains the radio frames configuration of 5 RN
Table 5 contains the radio frames configuration of 6 RN
Need to prove, above " scheduling sublayer node (or UE) " of indicating in last RN in all forms in fact can only dispatch UE.
By above-mentioned table 1 to the example of table 5 as seen, radio frames distribution of the present invention has following characteristics: (1) each node divides 4 subframes in the cycle to be in what state at a frame, relevant with the jumping figure of nodal distance DeNB, there are what RN irrelevant with this node back, therefore, when after increasing again new RN after the node of end, on the not impact of configuration of original RN; (2) when the number of relaying node more than or equal to 5 the time, except DeNB and RN1, RN
nAnd RN
n+3Have identical state, so RN
5After the radio frames configuration of node can reuse RN
2~ RN
4Sub-frame configuration, also, except base station and the via node adjacent with the base station, other via node repeats once every three via nodes at the state of this radio frames.
Step S204: with the base station of configuration and four via nodes state notifying base station and each via node at corresponding delivery frame number.
Each node that comprises the participation radio frames processing of base station can be notified by suitable signalling by the base station at the knowing of state of corresponding delivery frame number one by one to this node, also can be by carry out Configuration on each node.
Step S206: from the base station, successively to each via node transmission radio frames; After each via node is received radio frames, determine the delivery frame number of radio frames, and according to the delivery frame number of determining according to the state of this pre-configured node at this delivery frame number, carry out corresponding radio frames and process.
Below, the frame of the above-mentioned multi-hop relay of explanation divides the configuration scheme how to be used for the TD-LTE-A system as an example of 4 RN example.
At first, for simplicity, with " scheduling sublayer node or UE ", " receive the father node data or send data to father node ", " unavailable ", " scheduling UE " this one of four states represents with S1, S2, S3, S4 respectively.
Take sub-frame configuration 2 as example, each node is as shown in table 6 at the state of corresponding delivery frame number, and wherein D represents descending sub frame, and U represents sub-frame of uplink, and S represents special subframe, and S1, S2, S3 and S4 are respectively as mentioned above.
Table 6
For each node, all need to configure frame and divide the cycle, as be configured to 2 or 4, divide the cycle as 2 when configuring frame take 4 fields during as the cycle.At this moment, the state justify method of each node is: state S=SFN mod frame divides the cycle, and mod represents delivery.
When frame divides the cycle to be 2, after SFN mould 2, then be the front field of this radio frames or the state that rear field judges this node according to the result judgement of SFN mould 2.Wherein, SFN is system-frame (radio frames) number, is unified for the UE under each node and this node.
S1, S2, S3, S4 state are for radio frames (perhaps field), and Backhaul subframe and Access subframe are for subframe.To configure 2 as example, previous field for RN3 radio frames N is S1, the subframe #0 of this field and subframe #1 are that the Access subframe can be to scheduling UE, and subframe #2 ~ 4 can scheduling sublayer node or UE for the Backhaul subframe, certainly also subframe #0 ~ 2 are configured to the Access subframe, subframe #3 ~ 4 are configured to the Backhaul subframe.
In addition, support the ascending-descending subframes switching cycle of 5ms due to sub-frame configuration 2, therefore can carry out 4 times of frames take 4 fields as the cycle and divide.Therefore, its frame divides the cycle can shorten to 20ms.Wherein, subframe #0, #1, #5 and #6 are used for synchronous signal transmission, broadcast channel or paging(paging) etc., can not be used as the Backhaul subframe, therefore always as the Access subframe.
For the residing field of S2, actual can flexible configuration, namely can select a subframe in field as the Backhaul subframe.
For the sub-frame configuration of supporting 10ms up and down subframe switching cycle, needing 4 radio frames is to carry out frame the cycle to divide, and namely to divide the cycle be 40ms to frame.
When node was in S2 or S3 state, node can not be dispatched UE, for compatible with the UE of R8, for sub-frame of uplink, can directly not dispatch UE by node and realized; For descending sub frame, can be configured to the MBSFN subframe and realize.Also namely, when the state of corresponding delivery frame number was S2 or S3 state, the up Backhaul subframe in radio frames corresponding to this delivery frame number configured this node and does not dispatch UE when node; When the state of corresponding delivery frame number was S2 or S3 state, configuring the descending Backhaul subframe of this node in radio frames corresponding to this delivery frame number was the MBSFN subframe when node.
The MBSFN subframe can send to UE by system message, and 3GPP is as follows to the message semantic definition of MBSFN sub-frame allocation
RadioframeAllocationPeriod wherein is set to n4, and adopts the fourFrames mode, can carry out above-mentioned configuration.
When node is in S1 or S4 state, node can be dispatched UE, be non-MBSFN subframe with the descending Backhaul sub-frame configuration of this node in radio frames corresponding to corresponding delivery frame number, realize dispatching UE or child node by node self dispatching algorithm, when node is in the S4 state, dispatching algorithm can realize with reference to existing scheme, as being in S1 when node, father node can be seen its child node and make UE, then dispatch the UE of its child node or its service with the scheme of similar existing dispatching algorithm.
By above-mentioned configuration, node is processed when receiving radio frames accordingly, can realize the transfer of data of multi-hop relay.For example, when DeNB begin the N transmission frame number according to the time, it is the scheduling sublayer node that DeNB obtains its state at the N frame, in the Backhaul subframe to the RN1 the transmission of data; RN1 determines that this node is reception father node data at the state of N frame, receives the data of DeNB transmission in the Backhaul subframe; RN2 determines that this node is unavailable at the state of N frame, does not do any action; But simultaneously, RN3 determines that from the state in the N frame be the scheduling sublayer node, in the Backhaul subframe to the RN4 the transmission of data; RN4 determines to be reception father node data, the data of sending at Backhaul subframe reception RN3 from the state in the N frame.
By the present embodiment, adopt Backhaul link and Access isl frame minute mode to solve the transfer of data of multi-hop relay, this mode is not limited only to use in the TD-LTE system, can also be applied in other multihop relay system; And, with the sub-frame configuration mode that Backhaul link and Access isl frame divide, in the TD-LTE-A system of application, solve the Backhaul link of TD-LTE-A multi-hop relay and the resource of Access link and distribute.By the present embodiment, solve existing TD-LTE-A sub-frame configuration mode and be only applicable to the single-hop relaying, can't satisfy the transfer of data of multi-hop relay, satisfied the transfer of data of multi-hop relay, be convenient to the single-hop relaying of TD-LTE system to multi-hop relay evolution.
