Description
Technical field
The present invention relates to wireless communication system technologies, particularly the method for a kind of transmitting HARQ-ACK information.
Background technology
Long Term Evolution (LTE) system supports Frequency Division Duplexing (FDD) (FDD) and two kinds of duplex modes of time division duplex (TDD).Fig. 1 is the frame structure of TDD system.The length of each radio frames is 10ms, the field that it is divided into two length is 5ms.The time slot that it is 0.5ms that each field comprises 8 length and 3 special domain, i.e. descending pilot frequency time slot (DwPTS), protection interval (GP) and uplink pilot time slot (UpPTS), the length sum of these 3 special domain is 1ms.Each subframe is made of two continuous time slots, and namely k subframe comprises time slot 2k and time slot 2k+1.The TDD system supports 7 kinds of different upstream and downstream configurations, and is as shown in table 1.In the table 1, D represents descending sub frame, and U represents sub-frame of uplink, and S represents the above-mentioned special subframe that comprises 3 special domain.
The upstream and downstream configuration of table 1:LTE TDD
In order to improve user's transmission rate, enhancing (LTE-A) system of LTE system has been proposed.In LTE-A, (CC, Component Carrier) obtains larger bandwidth of operation by a plurality of unit of polymerization carrier wave, be carrier aggregation (CA, Carrier Aggregation), consists of the descending and up link of communication system, thereby support higher transmission rate.For example, in order to support the bandwidth of 100MHz, can obtain by the CC of 5 20MHz of polymerization.Here, each CC is called a residential quarter (Cell).To a UE, the base station can be configured among a plurality of Cell and work, and one of them is main Cell (PCC or PCell), and other Cell are called auxiliary Cell (SCC or SCell).
Stipulate in LTE-A TDD system: a plurality of Cell that condense together adopt identical upstream and downstream configuration, like this, mixed automatic retransfer request-the timing of affirmation (HARQ-ACK) information in various ce ll is the same with bundled window, and HARQ-ACK only transmits in main Cell, as shown in Figure 2.Main Cell, auxiliary Cell1 belong to same CA to auxiliary Cell3 among Fig. 2, and these Cell adopt identical upstream and downstream configuration, and the HARQ-ACK information of these Cell is all at the sub-frame of uplink of main Cell---transmission in subframe 2 and the subframe 7.
In fact, when the distance of the frequency domain between a plurality of Cell that carry out carrier aggregation was enough large, these Cell can adopt different uplink-downlink configuration fully and can not interfere with each other; In addition, each Cell adjacent may have been disposed different uplink-downlink configuration (frequently be different TD-SCDMA configuration such as the neighbour) frequently in the situation about having, at this moment, if continue these Cell are adopted identical uplink-downlink configuration, will produce more serious adjacent frequently interference, therefore, in the follow-up study of LTE-A, important problem is exactly how to study the different situation of uplink-downlink configuration of a plurality of Cell of effective support carrier aggregation.
A method is exactly: be the Cell of the identical definite transmitting HARQ-ACK information of Cell set of each TDD upstream and downstream configuration, as shown in Figure 3.Among Fig. 3:
The configuration of the upstream and downstream of main Cell and auxiliary Cell1 is identical, and the HARQ-ACK of main Cell and auxiliary Cell1 is all at the sub-frame of uplink of main Cell---transmission in subframe 2 and the subframe 7;
The configuration of the upstream and downstream of auxiliary Cell2 and auxiliary Cell3 is identical, and the HARQ-ACK of auxiliary Cell2 and auxiliary Cell3 is all at the sub-frame of uplink of auxiliary Cell2---transmission in the subframe 2,3,7 and 8;
According to method shown in Figure 3, will appear at same subframe sends HARQ-ACK information simultaneously at a plurality of Cell situation.But, be in the terminal of cell edge, because transmit power limited, its underpower is to support simultaneously in a plurality of Physical Uplink Control Channel (PUCCH) transmission HARQ-ACK information.
Another kind of Innovative method is regulation: in same sub-frame of uplink, HARQ-ACK only transmits at a Cell, if in this subframe a plurality of Cell that are determined for transmitting HARQ-ACK information are arranged, then select a Cell to be used for transmitting HARQ-ACK information according to priority, as shown in Figure 4.Under this mode, how specifically adopt which kind of transmission mode to carry out the transmission of HARQ-ACK information and base station is the technical problem that needs to be resolved hurrily to the UE indication transmission resource of using.

To having disposed the TDD system of carrier aggregation, the present invention supposes that the upstream and downstream configuration of a plurality of Cell of base station can be different.Similar with LTE-A, can will access the UE configuration effort of this base station at a Cell or a plurality of (some or all of) Cell.Among the present invention, to the configuration of the upstream and downstream of above-mentioned a plurality of Cell can be different situation, be consistent with LTE-A, for UE go physically each Cell of feedback in the control channel (PUCCH) HARQ-ACK regularly and bundled window remain definite according to the TDD upstream and downstream configuration of each Cell.The present invention is described below determines the transmission mode of HARQ-ACK information and the method that HARQ-ACK transmits employed PUCCH resource.Method proposed by the invention only is used for PUCCH.
In LTE-A, according to system configuration, the uplink-downlink configuration of a plurality of Cell of CA system is identical, at this moment, timing according to the HARQ-ACK of the TDD upstream and downstream that defines among LTE configuration also is identical with bundled window, and therefore, the HARQ-ACK of described a plurality of Cell only transmits in main Cell, and the timing of the HARQ-ACK of each Cell is the same, and the below considers that the uplink-downlink configuration of a plurality of Cell is not identical situation.
Among the present invention, the principle of HARQ-ACK transmission is: in same sub-frame of uplink, HARQ-ACK only transmits at a Cell, if in this subframe a plurality of Cell that are determined for transmitting HARQ-ACK information are arranged, then selects a Cell to be used for transmitting HARQ-ACK information according to priority.
Describe for example referring to Fig. 4:
In this CA system, have 4 Cell, wherein main Cell and auxiliary Cell1 belong to a frequency range, in this frequency range, main Cell is configured to transmitting HARQ-ACK information, and auxiliary Cell2 and auxiliary Cell3 belong to another frequency range, and auxiliary Cell2 is configured to transmitting HARQ-ACK information in this frequency range.
Suppose that the priority order from big to small that Cell selects is that main Cell is higher than auxiliary Cell2.
When subframe 2, main Cell and auxiliary Cell2 are sub-frame of uplink, according to the priority that arranges, select main Cell transmitting HARQ-ACK information, transmission be main Cell and auxiliary Cell1 subframe 4,5,6,8 ACK/NACK information and auxiliary Cell2 and auxiliary Cell3 subframe 5,6 HARQ-ACK information;
When subframe 3, only having auxiliary Cell2 is sub-frame of uplink, selects auxiliary Cell2 transmitting HARQ-ACK information, transmission be the HARQ-ACK information of auxiliary Cell2 and auxiliary Cell3 subframe 9;
When subframe 7, main Cell and auxiliary Cell2 are sub-frame of uplink, according to the priority that arranges, select main Cell transmitting HARQ-ACK information, transmission be main Cell and auxiliary Cell1 subframe 0,1,3,9 HARQ-ACK information and auxiliary Cell2 and auxiliary Cell3 subframe 0,1 HARQ-ACK information;

Take Fig. 4 as example, suppose: the base station is semi-static by the RRC signaling to be the transmission means that main Cell has disposed PUCCH form 3 and PUCCH channel selection 1b form, it is the transmission means that auxiliary Cell2 configuration PUCCH channel is selected the 1b form, so, on the sub-frame of uplink of main Cell transmitting HARQ-ACK information, the base station can adopt PUCCH form 3 or PUCCH channel to select 1b form transmitting HARQ-ACK information by RRC signaling terminal, on the sub-frame of uplink of auxiliary Cell2 transmitting HARQ-ACK information, the base station will adopt the PUCCH channel to select 1b form transmitting HARQ-ACK information by RRC signaling terminal.
Usually, if the length of HARQ-ACK is less than or equal to 4, the base station can be specified the PUCCH channel for the subframe of transmitting HARQ-ACK information and be selected the transmission means of 1b form, if the length of HARQ-ACK greater than 4, can be specified for the subframe of transmitting HARQ-ACK information the transmission means of PUCCH form 3.
Step 502: the base station will be used for the employed PUCCH resource notification of the subframe transmission HARQ-ACK information UE of transmitting HARQ-ACK information.
In this step, the base station will be carried out HARQ-ACK by the control of the through-put power in the Physical Downlink Control Channel (PDCCH) (TPC) territory and be transmitted employed PUCCH resource notification UE.
Particularly, suppose: the subframe of the current HARQ-ACK of carrying out communication is called the first subframe, Cell under this subframe is called a Cell, what transmit in the first subframe of a Cell is the HARQ-ACK information of the descending sub frame of Cell to a N Cell, so, adopt the TPC territory transmission TPC order among the PDCCH of corresponding descending sub frame of a Cell, adopt among Cell to the N Cell TPC territory among the PDCCH of any one descending sub frame in the corresponding descending sub frame of any one Cell except a Cell, carry out HARQ-ACK to the UE indication in the first subframe of a Cell and transmit employed PUCCH resource.Among the present invention, the value of N is more than or equal to 1, the number of the Cell under the HARQ-ACK information that represents to transmit on the first subframe of a Cell.When N equals 1, the HARQ-ACK information of the relevant descending sub frame that in fact only has a Cell that transmits on the first subframe of a Cell.
The TPC length of field is 2 bits, can transmit employed PUCCH resource by the different value indication HARQ-ACK of this 2 bit.
If among Cell to the N Cell except a Cell the corresponding descending sub frame of any one Cell all be not scheduled, what perhaps transmit in the first subframe of a Cell only is the HARQ-ACK information of the descending sub frame of a Cell, so, adopt the method for mapping resource of making an appointment to determine that carrying out HARQ-ACK in the first subframe of a Cell transmits employed PUCCH resource.For example: the method for mapping resource of stipulating in the 3GPPR8 platemaking technology standard.
Describe for example referring to Fig. 6:
When subframe 2, HARQ-ACK information is transmitted at main Cell, transmission be main Cell and auxiliary Cell1 subframe 4,5,6,8 HARQ-ACK information and auxiliary Cell2 and auxiliary Cell3 subframe 5,6 HARQ-ACK information.According to the present invention, TPC territory among main Cell subframe 4,5,6,8 the PDCCH is used for transmitting TPC order (concrete transmission method carries out according to prior art), and auxiliary Cell1 subframe 4,5,6,8 and auxiliary Cell2 and auxiliary Cell3 subframe 5,6 PDCCH in the TPC territory leave unused, the base station can adopt the TPC territory among the PDCCH in the above-mentioned subframe to carry out HARQ-ACK to the UE indication in the subframe 2 of main Cell to transmit employed PUCCH resource.Among Fig. 6, the frame of above-mentioned descending sub frame with the band point illustrated.
If auxiliary Cell1 subframe 4,5,6,8 and auxiliary Cell2 and auxiliary Cell3 subframe 5,6 PDCCH all be not scheduled, determine that with regard to adopting the method for mapping resource of stipulating in the 3GPP R8 platemaking technology standard carrying out HARQ-ACK in the subframe 2 of main Cell transmits employed PUCCH resource; If auxiliary Cell1 subframe 4,5,6,8 and any one or a plurality of being scheduled of auxiliary Cell2 and auxiliary Cell3 subframe 5,6 PDCCH is carried out the HARQ-ACK transmission with regard to the resource that adopts the TPC territory indication among the PDCCH that is scheduled in the subframe 2 of main Cell.
When subframe 7, HARQ-ACK information is transmitted at main Cell, transmission be main Cell and auxiliary Cell1 subframe 0,1,3,9 HARQ-ACK information and auxiliary Cell2 and auxiliary Cell3 subframe 0,1 HARQ-ACK information.According to the present invention, TPC territory among main Cell subframe 0,1,3,9 the PDCCH is used for transmitting TPC order (concrete transmission method carries out according to prior art), and auxiliary Cell1 subframe 0,1,3,9 and auxiliary Cell2 and auxiliary Cell3 subframe 0,1 PDCCH in the TPC territory leave unused, the base station can adopt the TPC territory among the PDCCH in the above-mentioned subframe to carry out HARQ-ACK to the UE indication in the subframe 7 of main Cell to transmit employed PUCCH resource.Among Fig. 6, above-mentioned descending sub frame is illustrated with the frame with grid.
When subframe 3, HARQ-ACK information is transmitted at auxiliary Cell2, transmission be the HARQ-ACK information of auxiliary Cell2 and auxiliary Cell3 subframe 9.At this moment, TPC territory among the PDCCH of auxiliary Cell2 subframe 9 can only be used for transmitting the TPC order, can not be used for carrying out HARQ-ACK to UE indication transmission in the subframe 3 of auxiliary Cell2 and transmit employed PUCCH resource, in this case, can adopt the method for mapping resource of stipulating in the 3GPP R8 platemaking technology standard to determine employed PUCCH resource; The TPC order need not be transmitted in TPC territory among the PDCCH of auxiliary Cell3 subframe 9, is used for carrying out HARQ-ACK to the UE indication in the subframe 3 of auxiliary Cell2 and transmits employed PUCCH resource.
When subframe 8, HARQ-ACK information is transmitted at auxiliary Cell2, transmission be the HARQ-ACK information of auxiliary Cell2 and auxiliary Cell3 subframe 4.
Step 503:UE determines to be used for carrying out the transmission mode that HARQ-ACK transmits employed PUCCH resource and HARQ-ACK information on each subframe according to the notice of base station.
Step 504: in the corresponding subframe of the Cell that be used for to send HARQ-ACK information, UE need to send in the HARQ-ACK information that this subframe sends each Cell of HARQ-ACK information.
Seen that by above-described embodiment the method for transmitting HARQ provided by the invention-ACK information is at least a its HARQ-ACK transmission mode on PUCCH of each Cell configuration of transmitting HARQ-ACK information by the base station.Because the path transmission loss difference that is in the Cell of different frequency range can be larger, in the constant situation of the maximum transmission power of supposition terminal, the coverage difference of HARQ-ACK information that is in the Cell of different frequency range can be larger.For the coverage difference that makes the HARQ-ACK information that is in different frequency range Cell as far as possible little, HARQ-ACK transmission for the Cell that is in the large frequency range of path transmission loss should adopt the PUCCH channel to select the 1b pattern as far as possible, because the PUCCH channel selects the needed signal to noise ratio of 1b pattern little; And should adopt PUCCH form 3 for the HARQ-ACK transmission of the Cell that is in the little frequency range of path transmission loss as far as possible, because PUCCH form 3 can improve the throughput of downlink data transmission.According to the concrete condition of each frequency range, dispose the method for corresponding HARQ-ACK transmission mode by provided by the invention for transmitting HARQ-each Cell of ACK information, can satisfy the demand of different frequency range HARQ-ACK transmission.And, the present invention is transmitted employed PUCCH resource notification UE by the TPC territory among the PDCCH with carrying out HARQ-ACK on each subframe, make UE can determine to carry out HARQ-ACK transmit employed PUCCH resource and based on transmission mode, even also can normally send HARQ-ACK information so that be in the terminal of cell edge, thereby effectively supported the different situation of uplink-downlink configuration of a plurality of Cell of carrier aggregation.
