Description

The feedback of response message, method of reseptance and device
Technical field
The present invention relates to the communications field, in particular to a kind of feedback of response message, method of reseptance and device.
Background technology
According to IMT-Advanced (International Mobile communications-Advanced, referred to as IMT-Advanced technical need), senior long term evolution (Long Term Evolution Advanced, referred to as LTE-A) In order to meet descending peak speed 1Gbps, the requirement of up peak speed 500Mbps, it is desirable to provide the transmission bandwidth of maximum 100MHz, But due to so big bandwidth continuous frequency spectrum rare, LTE-A proposes the solution of carrier aggregation.Carrier aggregation (Carrier Aggregation, referred to as CA) it is by 2 or more carrier units (Component Carrier, referred to as CC) polymerization Together to support bigger transmission bandwidth (being 100MHz to the maximum).Carrier aggregation is in third generation partner program at present (3rd Generation Partnership Project, referred to as 3GPP) the R10 stage is standardized.
Auxiliary authorizes and accesses (License Assisted Access, referred to as LAA) as the important research class of 3GPP Rel-13 Topic, LAA will authorize carrier wave to be operated by way of carrier aggregation with unauthorized carrier wave, wherein authorizes carrier wave as main plot, There is provided basic network connection and mobility capability for terminal, unauthorized carrier wave, as secondary cell, provides data channel for terminal Capacity boost, the therefore basic framework of LAA carrier aggregation will be using original carrier aggregation modes.Simultaneously, due to LAA Need execution first to listen when site channel accesses and say (Listen Before Talk, referred to as LBT) afterwards, therefore believe in LAA website The situation of part subframe is will appear from, how to the Physical Downlink Shared Channel (Physical in this part subframe in number sending Downlink Shared Channel, referred to as PDSCH) carry out down channel control information (Downlink Control Information, referred to as DCI) indicate and how to carry out HARQ-ACK feedback to be LAA research on standard urgent need to resolve Problem.
Wherein, retransmit in (Hybrid Automatic Repeat Request, referred to as HARQ) mode in hybrid automatic request, Make a start the code of transmission, can not only error detection, but also there is certain error correcting capability.After receiving terminal decoder receives code word, first First check error situation, if within the error correcting capability of code, automatically carry out error correction, if mistake is a lot, exceed code Error correcting capability, but mistake can be detected out, then receiving terminal passes through feedback channel to a decision signal of making a start it is desirable to make a start again Photos and sending messages.In OFDM (Orthogonal Frequency Division Multiplex, referred to as OFDM) system, Controlled by correct/error response (Acknowledgement/Negative-acknowledgement, referred to as ACK/NACK) Signaling processed, to represent transmission correct/error, to judge whether with this to need to retransmit, described ACK and NACK is referred to as HARQ-ACK response message.
In the related, it is related to the descending HARQ ACK/NACK of LAA (License Assisted Access) carrier aggregation Feedback problem, especially needs transmitting portion subframe after execution LBT (the Listen Before Talk) of LAA base station, and this portion The DCI information instruction of molecule frame sends in next subframe, descending HARQ ACK/NACK feedback therefore in this operative scenario Require study.
For in correlation technique, the ACK/NACK response message feedback problem of the HARQ of part subframe, there is presently no Effect solution.
