Background technology
In senior Long Term Evolution project time division duplex version 10 (LTE-A TDD Release10), introduce carrier aggregation concept to support more wide bandwidth transmission, be that two or more carrier waves are grouped together in together, to support LTE-A transmission bandwidth to be greater than the transmission of 20MHz.For the TD of the carrier aggregation of Release10, (intra-band) scene in band support, this frequency range (band) is the spendable Radio Resource frequency spectrum resource that International Telecommunication Union determines, if produce serious interference while adopting different up-downgoing proportionings can make up and descending transmitting-receiving, therefore each member carrier of polymerization (component carrier) adopts identical TDD up-downgoing proportioning
Table 1 is depicted as the ascending-descending subframes configuration mode of TDD, has wherein listed ascending-descending subframes configurations different in 7.Letter D represents that this subframe is descending sub frame; letter U represents that this subframe is sub-frame of uplink; letter S represents that this subframe is that special subframe (comprises descending pilot frequency time slot (DwPTS; Downlink Pilot Time Slot); uplink pilot time slot (UpPTS; Uplink Pilot Time Slot), protection time slot (Guard Period)).
Table 1
Be illustrated in figure 1 in prior art in a kind of typical Release10 the up-downgoing proportioning of each member carrier under carrier aggregation scene, wherein member carrier 1 (CC1) to member carrier 5 (CC5) all adopt shown in table 1 up-up-downgoing proportioning corresponding to downstream arrangements mark 1 (being designated hereinafter simply as configuration 1).
In Release10, in order to reduce the interference of isomery scene to control channel, introduce intersection carrier dispatching concept, the i.e. control information of a carrier wave can, by other carriers carry, distinguish by the carrier wave instruction territory (CIF) that adds 3bit at Downlink Control Information (DCI) above the carrier wave being scheduled.Be illustrated in figure 2 the schematic diagram of intersection carrier dispatching, wherein the Physical Downlink Control Channel (PDCCH) of carrier wave 0 (CC0) has carried the control information of these three carrier waves of CC0-CC2, distinguishes the Physical Downlink Shared Channel (PDSCH) of corresponding CC0-CC2 by the different values of CIF.
In Release11, will introduce (inter-band) carrier aggregation between frequency range, to reach the utilization of resources more flexibly.In the time that different frequency range uses different up-downgoing proportionings, may there is the scene that sub-frame of uplink conflicts with descending sub frame, as Fig. 3 a to Fig. 3 c is depicted as carrier aggregation different frequency range between frequency range and uses the schematic diagram of different up-downgoing proportionings.Wherein the CC1 of Fig. 3 a uses the configuration 1 shown in table 1, and CC2 uses the configuration 2 shown in table 1, has occurred respectively in subframe 3 and subframe 8 situation (subframe shown in ellipse) that ascending-descending subframes conflicts.The CC1 of Fig. 3 b uses configuration 3, CC2 to use configuration 4, occurs ascending-descending subframes conflict in subframe 4.The CC1 of Fig. 3 c uses configuration 2, CC2 to use configuration 4, all occurs the situation of ascending-descending subframes conflict in subframe 3, subframe 6 and subframe 7.
This situation can affect intersection carrier dispatching, therefore need to revise to adapt to new scene for the intersection carrier dispatching of Rel-10 definition.In Rel-10, also define the concept of community (Cell), the up CC that each Cell comprises a descending CC and is connected.
Enhancement mode Physical Downlink Control Channel is being discussed at present in Rel-11, i.e. e-PDCCH, transmits PDCCH to reach the object that strengthens control channel capacity by some region in PDSCH.Be illustrated in figure 4 the configuration schematic diagram of PDCCH and e-PDCCH.
The intersection carrier dispatching of Rel-10 can comprise that the PDCCH of a CC dispatches the situation of the PDSCH/ Physical Uplink Shared Channel (PUSCH) of another CC.In the situation that TDD different frequency range difference configures up and down, have four kinds of situations shown in Fig. 5.As Fig. 5 (a) (c) as shown in, if relation scheduling subframe corresponding to subframe that be scheduled is descending sub frame chronologically, no problem, can be according to the intersection carrier dispatching of Rel-10 definition.As Fig. 5 (b) (d) as shown in, if relation scheduling subframe corresponding to subframe that be scheduled is sub-frame of uplink chronologically, because scheduling subframe is sub-frame of uplink, cannot send mandate, therefore can not dispatch.

Embodiment
The present invention is applicable to full duplex scene, for configuration 0-configuration 6 these seven kinds of ratio of uplink subframe to downlink subframe, because mixing match has the complexity of considerable influence and design higher to specification, therefore the present invention will use the hypothesis in identical switching point cycle based on polymerization carrier wave.Suppose that different CC only configure the combination of the subframe proportioning of 5ms or 10ms.The CC of carrying scheduling authorization is called to scheduling CC, the CC that scheduling authorization transmits on other CC is called the CC that is scheduled simultaneously.
For the intersection carrier dispatching of conflict subframe, by using different control channel differentiations, across carrier dispatching, (control information of this carrier wave is by other carriers carry, (subframe before the control information of a certain subframe of this carrier wave is offset by this carrier wave or other carrier wave certain hours (subframe) is carried, as shown in Figure 2 b) as shown in Figure 2 a) and across subframe scheduling.For example, backward PDCCH monitors across subframe scheduling DCI, and e-PDCCH monitors across this carrier wave and across carrier dispatching DCI.
For the sub-frame of uplink of scheduling CC more than the sub-frame of uplink of the CC that is scheduled time, as shown in Figure 6.CC1 is scheduling CC, and CC2 is the CC that is scheduled.As shown in Figure 6,601-604 is the timing relationship that CC1 sends the uplink authorization of sub-frame of uplink.For the mandate of the PUSCH of the non-conflict subframe of the CC that is scheduled, can be according to the timing relationship of the mandate of the PUSCH of scheduling carrier wave, the uplink authorization of for example CC2 can be by the scheduling timing relation of CC1,, (shown in arrow 605) transmitted in the mandate of the subframe 2 of CC2 in the subframe 6 of CC1, and (shown in arrow 607) transmitted in the mandate of the subframe 7 of CC2 in the subframe 1 of CC1.Corresponding PHICH still transmits at the CC (being CC1) that sends uplink authorization upper, and transmits by the PHICH sequential relationship of CC1.
Intersect carrier dispatching for the downstream grants of conflict subframe by the scheduling CC of the subframe of a certain subframe (time) skew before this conflict subframe.For example, when this skew is made as three subframes, the DCI of CC2 subframe 3 transmits (shown in arrow 606) in the subframe 0 of CC1, and the DCI of CC2 subframe 8 transmits (shown in arrow 608) in the subframe 5 of CC1.Because CC1 subframe 0 will send the PDCCH of subframe 0 on CC1 in the time intersecting carrier dispatching, also to transmit the PDCCH of subframe 0 and the subframe 3 of CC2, in order to distinguish the subframe 0 of CC2 and the DCI of subframe 3, whether the DCI that therefore distinguishes CC2 by monitoring different control channel ground methods is across subframe scheduling.The DCI that UE monitors on the PDCCH of scheduling CC is the DCI across subframe scheduling, i.e. the DCI of subframe 3; Be this carrier dispatching and across carrier dispatching DCI at the DCI of e-PDCCH monitoring, and the DCI of scheduling CC subframe 0 and the DCI (shown in arrow 609) of the CC subframe 0 that is scheduled.
Situation for scheduling CC descending sub frame more than the CC that is scheduled, as shown in Fig. 7 (a), wherein 701-703 is the timing relationship that scheduling CC sends sub-frame of uplink uplink authorization.The mandate of the descending sub frame of each CC of being scheduled still can intersect carrier dispatching by scheduling CC, as shown in 708.For the uplink authorization (comprising conflict subframe and non-conflict subframe) of the CC that is scheduled, close to tie up in the corresponding subframe of scheduling CC according to the scheduling timing of this CC self and send, the subframe 7 of for example CC2,8 mandate should be in the subframe of CC2 1, on 4, send, therefore in the time intersecting carrier dispatching, will send and authorize (shown in arrow 704,705) by the subframe Isosorbide-5-Nitrae of CC1 respectively.In like manner, the mandate of CC2 subframe 2,3 sends (shown in arrow 706,707) in CC1 subframe 6,9.But PHICH is according to the subframe transmission of scheduling CC, do not increase new PHICH subframe, the position that is the PHICH of CC 1 is still subframe 3 and subframe 8, and these two PHICH resources need to be fed back the subframe 3 of CC2 and the Ack/Nack information of subframe 8 (shown in arrow 709 and 710).
For sub-frame configuration 0, owing to existing 1 subframe to send the situation of 2 subframe mandates, may send 2 PHICH set a PHICH resource accordingly, therefore, for avoiding confusion and simplifying system, while no matter dispatching CC or the CC that is scheduled use sub-frame configuration 0, will limit I PHICH=0.
Scheme 2 for scheduling CC descending sub frame more than the situation of the CC that is scheduled, as shown in Fig. 7 (b).701-703 is the timing relationship that scheduling CC sends sub-frame of uplink mandate.For non-conflict subframe, for example subframe 2 and 7, the CC that is scheduled will intersect carrier dispatching (shown in arrow 704,706) by the timing relationship of scheduling CC.For conflict subframe, for example subframe 3 and 8, the CC that is scheduled will authorize (shown in arrow 705,707) according to the transmission in the subframe of corresponding scheduling CC of self timing relationship.
PHICH is according to the subframe transmission of scheduling CC, do not increase new PHICH subframe, the position that is the PHICH of CC 1 is still subframe 3 and subframe 8, and these two PHICH resources need to be fed back the subframe 3 of CC2 and the Ack/Nack information of subframe 8 (shown in arrow 708 and 709).
For sub-frame configuration 0, owing to existing 1 subframe to send the situation of 2 subframe mandates, may send 2 PHICH set a PHICH resource accordingly, therefore, for avoiding confusion and simplifying system, while no matter dispatching CC or the CC that is scheduled use sub-frame configuration 0, will limit IPHICH=0.

Step 901: whether the sub-frame of uplink (descending sub frame) that judges scheduling member carrier is more than (being less than) the member's carrier wave that is scheduled, if execution step 902, otherwise, execution step 905.
Step 902: judgement is scheduled, and the up-downgoing of the subframe corresponding with scheduling member carrier is consistent for the subframe of member's carrier wave, if so, performs step 904, otherwise, execution step 903.
Step 903: the PDCCH of the scheduling member carrier of skew is upper sometime before described descending sub frame sends across subframe scheduling DCI sends this carrier dispatching and across carrier dispatching DCI on e-PDCCH.
Step 904: by scheduling member carrier timing relation, the member's carrier wave that is scheduled is intersected to carrier dispatching, but PHICH is according to the location transmission of scheduling CC.
