Description

A kind of method and apparatus being used for transmission ascending control information

Technical field

The present invention relates to field of communication technology more particularly to a kind of technologies being used for transmission ascending control information.

Background technology

In heterogeneous network, the introducing of low-power network node faces lot of challenges, such as uplink (UL, up link)/under Mobile robustness (mobility robustness), frequency error factor, signal occurs for row (DL, down link) unbalanced power Overload, and resource utilization is low etc. between node caused by non-ideal backhaul (non-ideal backhaul), this is significantly Limit network performance.

In 3GPP RAN2, dual link (dual-connectivity) is defined as the effective solution to solve the above problems Scheme.In dual link, user equipment (UE) while at least two network nodes are connected to, identical or different frequency can be operated in Rate.Dual link typically can be applied to, by non-ideal backhaul, such as have pine delay and the backhaul of capacity requirement, be connected to each other Multiple base stations such as eNB (evolved-NodeB).

Carrier wave polymerization (CA, Carrier aggregation) can be used for realizing dual link, wherein a wireless connection can It is operated on portion of carriers component (CC, component carrier), and other wireless connections can be operated on other CC, As shown in Figure 2, wherein UE be connected to simultaneously macro-cell eNB and small-cell eNB, macro-cell eNB and It is configured for UE by non-ideal backhaul non-ideal backhaul connections, macro-cell eNB between small-cell eNB One group of carrier component such as CC1 and CC2, small-cell eNB are that UE configures one group of carrier component such as CC3 and CC4.

However, in 3GPP LTE-Advanced Release10/11, by multiple serving cells of CA polymerizations by identical ENB control, ascending control information (UCI, uplink control information) notice have some rule, such as extremely More Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) or the shared letter of physical uplink Road (PUSCH, Physical Uplink Shared Channel) can transport UCI, and the PUCCH of carrying UCI and carrying UCI PUSCH cannot be transmitted in same subframe.

To realize that the dual link with CA, multiple serving cells of aggregation need to be controlled by individual eNB, therefore, traditional CA Strategy should be enhanced, and such as UCI should be transmitted rather than only right on multiple carrier components (CC, component carrier) It should be transmitted on the CC of main plot (PCC, primary cell), this just needs the multiple carryings of parallel transmission simultaneously on different CC The PUCCH and PUSCH of the PUSCH and simultaneous transmission carrying UCI of the PUCCH of UCI, the multiple carrying UCI of simultaneous transmission.

Therefore, for CA, need new UCI be multiplexed rule and the resource allocation about different UCI should be reconsidered with Support the dual link based on CA.

In current 3GPP LTE-Advanced Release10/11, according to the introduction of CA, multiple PUSCH can be in difference The upper parallel transmissions of CC, then simultaneous transmission PUSCH and PUCCH are possible on identical or different CC.

From the point of view of high level, every CC can be used as the independent cell with its cell ID.Main serving cell (PCell, Primary Serving Cell) it is defined as the cell being initially configured during initial connection, about safety, non-access Layer (NAS, Non-Access Stratum) mobile message, the system information (SI, System Information) for configuring cell, And it in terms of some low layer functions, plays an important role.Auxiliary serving cell (SCell, Secondary Serving Cell) For the cell for being merely provided for additional radio resource being configured after initial connection.

For CA, (it includes hybrid automatic repeat-request response/non-response (HARQ ACK/NACK, Hybird to UCI Automatic Repeat reQuest ACKnowledgement/Non ACKnowledgement) signaling, scheduling request (SR, scheduling request) and channel state information (CSI, channel state information)) it can support At most 5 descending carrier components (DL CC).In Release10/11, UCI is time-multiplexed in a up-link carrier component On (UP CC), i.e. UCI can not be divided across multiple UL CC.

In the prior art, realize that the basic principle of the strategy of UCI multiplexings is removing aperiodicity CSI, all UCI are re-used On the uplink main plot of PSell, if the PSell is scheduled in identical subframe, otherwise, secondary cell (SCC, Secondary Cell) it is used, it is existing to realize that the strategy of UCI multiplexings is exemplified below：

1. all UCI being multiplexed on PUCCH are only transmitted on the UL PCC of PCell；

2. being transmitted on the PUSCH of uplink CC of the aperiodicity CSI report corresponding to the downlink CC of triggering this report；

3. if be unable to simultaneous transmission PUCCH and PUSCH, and there are at least one PUSCH transmission, then all UCI are re-used On PUSCH：

● when if PCC PUSCH are transmitted, any periodicity CSI feedback and/or HARQ-ACK report multiplexings are in PCC It is transmitted on PUSCH；

If PCC PUSCH are not transmitted, and there are one SCC PUSCH be transmitted when, UCI is multiplexed on SCC PUSCH Transmission；

If in same subframe, more than one SCC PUSCH transmissions occur, periodical CSI feedback and/or HARQ- ACK reports are multiplexed on the SCC PUSCH of the serving cell with minimum cell index and transmit.

If 4. can simultaneous transmission PUCCH and PUSCH, and there are at least one PUSCH transmissions：

● HARQ-ACK is transmitted on PUCCH；

● when if PCC PUSCH are transmitted, periodical CSI feedback multiplexing is transmitted on PCCPUSCH；

If PCC PUSCH are not transmitted, and there are one SCC PUSCH be transmitted when, periodical CSI is multiplexed in SCC It is transmitted on PUSCH；

If in same subframe, more than one SCC PUSCH transmissions occur, in the service with minimum cell index Periodicity CSI is transmitted on the SCC PUSCH of cell.

5. when for being deposited in the case of a conflict between the periodical CSI and aperiodicity CSI of identical or different DL CC, Periodical CSI is dropped, and only aperiodicity CSI is transmitted.

According to the above current UCI multiplex strategies, should be transmitted by a CC even for different DL CC, all UCI, The CC can be connected to network node such as macrocell eNB (macro-cell eNB) or cell eNB (small-cell eNB). Because of the non-ideal backhaul of dual link, periodical CSI or HARQ-ACK can have significant delay, significantly affect dispatching efficiency and System performance.
