Description

A kind of method and apparatus for transmitting uplink control information
Technical field
The present invention relates to communication technical field, particularly relate to a kind of technology for transmitting uplink control information.
Background technology
In heterogeneous network, the introducing of low-power network node faces lot of challenges, such as up (UL, up link)/descending (DL, down link) unbalanced power, mobile robustness (mobility robustness), frequency error factor, generation signal overloading, and between the node to cause because of imperfect backhaul (non-ideal backhaul), resource utilization is low etc., this significantly limits network performance.
In 3GPP RAN2, dual link (dual-connectivity) is defined as the effective solution solved the problem.In dual link, subscriber equipment (UE) is connected at least two network nodes simultaneously, and it can be operated in identical or different frequency.Dual link typically can be applicable to by imperfect backhaul, and as having the backhaul of pine delay and capacity requirement, the multiple base stations be connected to each other are as eNB(evolved-NodeB).
Carrier aggregation (CA, Carrier aggregation) can be used to realize dual link, wherein, one wireless connections can be operated in portion of carriers component (CC, component carrier) on, and other wireless connections can be operated on other CC, as shown in Figure 2, wherein, UE is connected to macro-cell eNB and small-cell eNB simultaneously, connected by imperfect backhaul non-ideal backhaul between macro-cell eNB and small-cell eNB, macro-cell eNB is that UE configures one group of carrier component as CC1 and CC2, small-cell eNB is that UE configures one group of carrier component as CC3 and CC4.
But, in 3GPP LTE-Advanced Release10/11, multiple Serving cells of being polymerized by CA are controlled by identical eNB, ascending control information (UCI, uplink control information) notice have some rule, a such as Physical Uplink Control Channel (PUCCH at the most, Physical Uplink Control Channel) or Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel) can UCI be transported, and the PUCCH of carrying UCI can not transmit with the PUSCH of carrying UCI in identical subframe.
For realizing the dual link with CA, multiple Serving cells of assembling need be controlled by independent eNB, therefore, traditional C A strategy should be enhanced, and such as UCI in the upper transmission of multiple carrier component (CC, component carrier) instead of only should correspond to main plot (PCC, primary cell) CC on transmission, this just needs the PUCCH of the UCI of the multiple carrying of parallel transmission simultaneously on different CC, transmits the PUSCH of multiple carrying UCI simultaneously, and PUCCH and PUSCH of transmission bearer UCI simultaneously.
Therefore, for CA, need the multiplexing rule of new UCI and should be reconsidered to support the dual link based on CA about the Resourse Distribute of different UCI.
In current 3GPP LTE-Advanced Release10/11, according to the introduction of CA, multiple PUSCH can on different CC parallel transmission, then it is possible on identical or different CC, transmitting PUSCH and PUCCH simultaneously.
From high level, each CC can be used as the independent community with its community ID.Main Serving cell (PCell, Primary Serving Cell) be defined as in initial attach procedure by the community of initial configuration, about safety, Non-Access Stratum (NAS, Non-Access Stratum) mobile message, allocating cell system information (SI, System Information), and some low layer function aspects, it plays an important role.Auxiliary serving cell (SCell, Secondary Serving Cell) for be configured after initial connection only for providing the community of extra Radio Resource.
For CA, UCI(it comprise hybrid automatic repeat-request response/non-response (HARQ ACK/NACK, Hybird Automatic Repeat reQuest ACKnowledgement/Non ACKnowledgement) signaling, dispatch request (SR, scheduling request), and channel condition information (CSI, channel state information)) 5 descending carrier components (DL CC) at the most can be supported.In Release10/11, UCI is time-multiplexed on a up-link carrier component (UP CC), and namely UCI can not divide across multiple UL CC.
In prior art, the general principle realizing the multiplexing strategy of UCI is removing aperiodicity CSI, all UCI are multiplexed on the up main plot of PSell, if this PSell is scheduled in identical subframe, otherwise, (SCC, Secondary Cell) is used in one Ge Fu community, and the multiplexing strategy of the existing UCI of realization is exemplified below:
1. multiplexing all UCI on PUCCH only transmit on the UL PCC of PCell;
2. aperiodicity CSI report is transmitted on the PUSCH triggering the up CC corresponding to the descending CC of this report;
If 3. can not transmit PUCCH and PUSCH simultaneously, and there is at least one PUSCH transmission, then all UCI are multiplexed on PUSCH:
● when if PCC PUSCH is transmitted, any periodicity CSI feedback and/or HARQ-ACK report are multiplexingly transmitted on PCC PUSCH;
-Ruo PCC PUSCH is not transmitted, and when having a SCC PUSCH to be transmitted, UCI is multiplexed on SCC PUSCH and transmits;
-Ruo is in identical subframe, and more than one SCC PUSCH transmission occurs, and periodically CSI feedback and/or HARQ-ACK report are multiplexed in that the SCC PUSCH of the Serving cell with minimum cell index is upper to be transmitted.
If 4. can transmit PUCCH and PUSCH simultaneously, and there is at least one PUSCH transmission:
● HARQ-ACK transmits on PUCCH;
● when if PCC PUSCH is transmitted, periodically CSI feedback is multiplexing transmits on PCCPUSCH;
-Ruo PCC PUSCH is not transmitted, and when having a SCC PUSCH to be transmitted, periodically CSI is multiplexed on SCC PUSCH and transmits;
-Ruo is in identical subframe, and more than one SCC PUSCH transmission occurs, transmission periodically CSI on the SCC PUSCH of Serving cell with minimum cell index.
5. ought for depositing in the case of a conflict between the periodicity CSI of identical or different DL CC and aperiodicity CSI, periodically CSI is dropped, and only aperiodicity CSI is transmitted.
According to above current UCI multiplex strategy, even should by a CC transmission for different DL CC, all UCI, this CC can be connected to network node as macrocell eNB(macro-cell eNB) or small-cell eNB(small-cell eNB).Because of the imperfect backhaul of dual link, periodically CSI or HARQ-ACK can have significant delay, its appreciable impact dispatching efficiency and systematic function.
