Description
Technical field
The present invention relates to field of mobile wireless communication, particularly relate to the sending method and the subscriber equipment of channel condition information in the wireless communication system.
Background technology
In long evolving system (LTE:Long Term Evolution); The up control signaling of transmission that needs has correct/error response message (ACK/NACK:Acknowledgement/Negative Acknowledgement), and three kinds of forms of the information (CSI:Channel State Information) of reflection down physical channel state: channel quality indication (CQI:Channels quality indication), pre-coding matrix indication (PMI:Pre-coding Matrix Indicator), order indication (RI:Rank Indicator).
In the LTE system; The ACK/NACK response message goes up at Physical Uplink Control Channel (PUCCH:Physical Uplink Control ChanBel) to be transmitted with form 1/1a/1b (PUCCH format1/1a1/b); When if subscriber equipment (UE:User Equipment) needs to send upstream data; Then go up transmission at Physical Uplink Shared Channel (PUSCH:Physical Uplink Shared Channel); The CSI's that reports can be periodic, also can be that acyclic, concrete feedback is as shown in table 1:
| Scheduling method | Periodicity CQI reporting channel | Aperiodicity CQI reporting channel |
| Frequency is non-selective | ?PUCCH | |
| Frequency selectivity | ?PUCCH | ?PUSCH |
Corresponding uplink physical channel gives the correct time on table 1 periodicity and the aperiodicity
Wherein, if UE need not send upstream data, then with form 2/2a/2b (PUCCH format2/2a/2b) transmission, if when UE need send upstream data, then the CSI of periodic report transmits on PUSCH the CSI of periodic report on PUCCH; The CSI that aperiodicity reports only transmits on PUSCH.The different CQI of the semi-static configuration UE of high-level signaling periodic report on PUCCH, PMI and RI information, on give the correct time use report pattern as shown in table 2, each downlink transfer pattern all has the corresponding pattern that reports.
Table 2 reports pattern
CQI/PMI information and RI information reporting type in 4 have been defined among the LTE; Promptly support UE to select the reporting types 1 of subband CQI feedback information; Support the reporting types 2 of broadband CQI information and PMI feedback information, support the reporting types 3 of RI feedback information, support the reporting types 4 of broadband CQI information.
In order to satisfy (the International Telecommunication Union-Advanced of senior International Telecommunications Union; Abbreviate ITU-Advanced as) requirement; Senior Long Term Evolution (Long Term Evolution Advanced as the LTE evolution standard; Abbreviating LTE-A as) system need support bigger system bandwidth (reaching as high as 100MHz), and need backward compatibility LTE prior standard.On the basis of existing LTE system, can merge through bandwidth and obtain bigger bandwidth the LTE system, this technology is called carrier aggregation (Carrier Aggregation abbreviates CA as) technology.The availability of frequency spectrum, alleviation frequency spectrum resource that this technology can improve the IMT-Advance system are in short supply, and then optimize the utilization of frequency spectrum resource.The LTE system bandwidth of said carrier aggregation can be regarded component carrier (Component Carrier as; Abbreviate CC as); Each component carrier also can be called a Serving cell (Serving Cell), that is to say that a frequency spectrum can be polymerized by n component carrier (or Serving cell).The resource of a R10 UE is made up of n the component carrier (or Serving cell) of frequency domain, and wherein, a Serving cell is called main plot (Primary cell) or principal component carrier wave, and all the other Serving cells are called auxilliary sub-district (Secondary cell) or auxilliary component carrier.In the LTE-A system, CQI/PMI information, the reporting types of RI information also expands to: support UE to select the reporting types 1 of subband CQI information; Support the reporting types 1a of subband CQI and second PMI feedback, support the reporting types 2 of broadband CQI information and PMI feedback information, reporting types 2b; Reporting types 2c supports the reporting types 2a that broadband P MI feeds back, and supports the reporting types 3 of RI feedback information; Support the reporting types 4 of broadband CQI information; Support the reporting types 5 of RI and broadband P MI feedback, support the reporting types 6 of RI and PTI (Precoder Type Indication, the indication of precoding type).
In the discussion process of LTE-A, the PUCCH form that proposes several kinds of heavy loads of introducing is supported cycle CSI transmission, such as present PUCCH form 3, and the PUCCH form 3 that perhaps strengthens.
LTE-A system regulation: if UE has disposed a plurality of descending Serving cells, in arbitrary subframe, UE only transmits the cycle CSI information of a descending Serving cell, i.e. the cycle CSI of a plurality of Serving cells report adopts time-multiplexed mode to transmit.If prior art has also been stipulated the processing mode of the cycle CSI informational needs of a plurality of Serving cells in same subframe transmission: select a cycle CSI message transmission that descending Serving cell is corresponding, destroy the corresponding cycle CSI information of other descending Serving cells.Concrete system of selection is: the cycle CSI reporting types corresponding priorities according to each descending Serving cell is selected; Promptly select the cycle CSI message transmission of the high Serving cell of reporting types priority; If the reporting types corresponding priorities of the cycle CSI information that a plurality of descending Serving cells are corresponding is identical; Select according to the Serving cell index value, promptly select the cycle CSI message transmission of the minimum Serving cell of Serving cell index value.The reporting types that priority is the highest is: reporting types 3, reporting types 5, reporting types 6 and reporting types 2a; The reporting types that priority is minimum is: reporting types 1 and reporting types 1a; The priority of other reporting types is between the two.
Do not support the cycle CSI report transmission simultaneously of a plurality of descending Serving cells in the LTE-A system; But adopt time-multiplexed mode to transmit the cycle CSI report of a plurality of descending Serving cells; So obtaining the channel quality information of each descending Serving cell, the base station postpones; Scheduling is exerted an influence, thereby influence the throughput of system, the waste ascending resource.Transmit when adopting time-multiplexed mode can not avoid the cycle CSI information of same of a plurality of descending Serving cells fully; When the CSI report of the cycle of a plurality of descending Serving cells need be transmitted simultaneously; Only send the cycle CSI report of a descending Serving cell; Destroy the cycle CSI report of other descending Serving cells, also can make the decreased performance of system.And in follow-up version; Because the introducing of new technology; Like cooperative multicast system (Coordinated Multi-Point Transmission and Reception; Abbreviating CoMP as) the descending sub-district number of the cycle CSI report of need sending also can increase, and postpone or destroy and can not ignore the influence of system.

The cycle CSI that supposes 4 sub-districts of high-level signaling indication support sends simultaneously; Needing the descending sub-district number of the cycle CSI of transmission in the current subframe is 6; UE selects the cycle CSI of 4 sub-districts to report from 6 descending sub-districts, and the cycle CSI of these 4 descending sub-districts is respectively
and
In the present embodiment, predefined rule is a rule two, the new PUCCH form transmission cycle CSI of fixing use.UE fixes and uses new PUCCH form transmission cycle CSI according to rule two.
Suppose under the conventional CP that new PUCCH form is: the PUCCH form a of enhancing shown in Figure 5, under the expansion CP; New PUCCH form is: the PUCCH form a of enhancing shown in Figure 6, wherein cataloged procedure shown in Fig. 3 (b), each RM (L; O) list entries ascending control information sequence 1; Ascending control information sequence 2, ascending control information 3, ascending control information 4 are respectively by a kind of the obtaining in the following several kinds of schemes:
