Description

The sending method and device of ascending control information
Technical field
The present invention relates to the communications field, in particular to the sending method and device of a kind of ascending control information.
Background technology
Long Term Evolution (Long Term Evolution, referred to as LTE) system is the important meter of third generation partnership Draw, Fig. 1 shows the structural representation of basic frame structure in LTE system, as shown in figure 1, frame structure be divided into radio frames, field, Four grades of subframe and time slot, wherein, a length for radio frames is 10ms, and a radio frames are the half of 5ms by two length Frame is constituted, and, by 5 length for the subframe of 1ms is constituted, a subframe is by two length for the time slot of 0.5ms is constituted for a field.
In the descending HARQ of LTE, Physical Downlink Shared Channel (Physical Downlink Shared Channel, Referred to as PDSCH) correct/error (Acknowledgement/Negative Acknowledgement, referred to as ACK/ NACK) response message, when terminal (User Equipment, referred to as UE) is without Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH) when, it is physically row control channel (Physical Uplink Control Channel, referred to as PUCCH) on send.LTE defines various PUCCH format (format forms), bag PUCCH format 1/1a/1b and format 2/2a/2b are included, wherein format 1 is used for sending the dispatch request of UE (Scheduling Request, referred to as SR) signal, the ACK/NACK that format 1a and 1b are respectively intended to feed back 1 bit should The ACK/NACK response messages of information and 2 bits are answered, format 2 is used for sending channel condition information (Channel States Information, referred to as CSI).
In LTE system, in FDD (Frequency Division Duplex, referred to as FDD) system, due to Ascending-descending subframes are one-to-one, so when PDSCH only includes a transmission block, UE will feed back the ACK/NACK of 1 bit Response message, when PDSCH includes two transmission blocks, UE will feed back the ACK/NACK response messages of 2 bits, and UE uses PUCCH Formatla/1b sends the ACK/NACK response messages of 1/2 bit.Time division duplex (Time Division Duplex, referred to as TDD) in system, due to ascending-descending subframes is not one-to-one, that is to say, that the corresponding ACK/NACK of multiple descending sub frames Response message needs to be sent on a PUCCH channel for sub-frame of uplink, wherein, the corresponding descending sub frame collection of sub-frame of uplink is charge-coupled Into " bundling window ".The sending method of ACK/NACK response messages has two kinds：One kind is bundling (binding sides Method), the core concept of the method is the corresponding transmission block of each descending sub frame for needing to be fed back on the sub-frame of uplink ACK/NACK response messages carry out logic and operation.If a descending sub frame has 2 transmission blocks, UE will feed back 2 bits ACK/NACK response messages, if a descending sub frame only one of which transmission block, UE will feed back the ACK/NACK responses letter of 1 bit Breath, UE sends the ACK/NACK response messages of this 1/2 bit using PUCCH format 1a/1b；Another kind is Multiplexing (Multiplexing with Channel Selection, Channel assignment) method, the core of the method is thought Want to be represented using modulation symbol different on different PUCCH channels and the channel and need what is fed back on the sub-frame of uplink The different feedback states of descending sub frame, if there is multiple transmission blocks on descending sub frame, then first by the multiple transmission of descending sub frame The ACK/NACK of block feedback carries out Channel assignment again after carrying out logical AND (Spatial Bundling), and UE uses format 1b With channel selection (selection of form 1b combined channels) send ACK/NACK response messages.
In order to meet senior International Telecommunication Union (International Telecommunication Union- Advanced, referred to as ITU-Advanced) requirement, as senior long term evolution (the Long Term of the evolution standard of LTE Evolution Advanced, referred to as LTE-A) the bigger system bandwidth (reaching as high as 100MHz) of system needs support, and Need the existing standards of backward compatibility LTE.On the basis of existing LTE system, the bandwidth of LTE system can be merged To obtain bigger bandwidth, this technology is referred to as carrier aggregation (Carrier Aggregation, referred to as CA) technology, the skill Art can improve IMT-Advance systems the availability of frequency spectrum, alleviate frequency spectrum resource it is in short supply, and then optimize frequency spectrum resource profit With.In order to obtain peaks spectrum efficiency higher, in lte-a system, many transmission antennas of up support, i.e., up support Dan Tian Line transmission mode and multi-antenna transmission pattern.The reliability of transmission can be improved in view of transmission diversity mode, improvement connects The signal to noise ratio of the collection of letters number, so the discussion for PUCCH channel multi-antenna transmission patterns is all based on transmission diversity mode, and And for the scene of four antennas, all obtained by two antenna virtualizations.
In the system for introducing carrier aggregation, the carrier wave being polymerized referred to as component carrier (Component Carrier, referred to as CC), also referred to as one Serving cell (Serving Cell).It is also proposed that principal component carrier wave/small Area (Primary Component Carrier/Cell, referred to as PCC/PCell) and auxiliary component carrier/cell (Secondary Component Carrier/Cell, referred to as SCC/SCell) concept, in the system for carrying out carrier aggregation, at least wrap Containing a main serving cell and auxiliary serving cell, wherein, main serving cell is constantly in state of activation.Terminal for LTE-A For, if could support up 4 bit ACKs/NACK response messages, use format 1b with channel selection Send ACK/NACK response messages；If supporting to be more than 4 bit ACKs/NACK response messages, format 1b can be used With channel selection send ACK/NACK response messages, it is also possible to sent out using the new PUCCH format3 for introducing ACK/NACK response messages are sent, specifically used which kind of mode is sent ACK/NACK response messages and configured by high-level signaling.
Orthogonal space resource transmission diversity (Space Orthogonal-Resource Transmit Diversity, letter Referred to as SORTD) be PUCCH formatl/1a/1b, format2/2a/2b and format3 under current multiaerial system transmitting Diversity scheme, the principle of SORTD is that identical signaling is transmitted on different antennas using different orthogonal resources, for channel For selection, due to the increase at double of the orthogonal resource number that uses, so not supported different in the version of Rel-10 Identical signaling is transmitted on antenna.In later release, for FDD system, at most using 4 PUCCH resources in multiple antennas mould It is transmitted under formula, for TDD system, the problem that Channel assignment is transmitted under multi-antenna mode cannot be also realized now.
For above-mentioned problem, effective solution is not yet proposed at present.
