Embodiment
Below in conjunction with drawings and Examples, the present invention will be described in further detail.It is it should be appreciated that described herein Specific embodiment only to explain the present invention, is not intended to limit the present invention.
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with accompanying drawing to the present invention Embodiment be described in detail.It should be noted that in the case where not conflicting, in the embodiment and embodiment in the application Feature can mutually be combined.
First embodiment
First embodiment of the invention provides a kind of sending method of ascending control information, and Fig. 1 is in the embodiment of the present invention The flow chart of the sending method of row control information, as shown in figure 1, the flow includes：
Step 101：Terminal from subframe index be n0Descending sub frame start to receive downlink information, S1 in S1 descending sub frame For the positive integer more than zero.
When actually implementing, terminal can be semi-duplex type B terminal, and exemplarily, terminal is HD-FDD UE.Son Frame index is n0Subframe can be：The subframe of default subframe or signaling instruction.
Here downlink information can be and machine type communication Physical Downlink Control Channel (MTC Physical Downlink Control Channel, abbreviation MPDCCH) corresponding to Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), do not correspond to MPDCCH PDSCH or indicating downlink semi-continuous scheduling (Semi-Persistent Scheduling, SPS) release MPDCCH, NB-IoT system in arrowband Physical Downlink Control Channel (Narrowband Physical Downlink Shared Channel) etc..
Step 102：Terminal confirms ACK responses letter according to the downlink information and corresponding hybrid automatic repeat-request HARQ- The timing relationship of breath, HARQ-ACK response messages corresponding to the downlink information are sent on S2 sub-frame of uplink.
Here, S2 sub-frame of uplink of above-mentioned record can be continuous sub-frame of uplink,QiFor i-th Corresponding number of sub-frames when HARQ-ACK response messages transmit, QiObtained according to the number of repetition of configuration；The downlink information is With MPDCCH corresponding to Physical Downlink Shared Channel PDSCH, do not correspond to MPDCCH PDSCH or indicating downlink SPS release MPDCCH。
Optionally, M value is preset value, and either M value determines according to S1 and preset value K or M value is descending according to S1 The downlink information number X and preset value K included in subframe is determined.Preferably, M=ceil (X/K), wherein, ceil represents upward Round, X represents the downlink information number included in S1 descending sub frames.
Further, K is equal to 4, or the value that K is signal deployment.
Optionally, the timing relationship of the downlink information and corresponding HARQ instance-ACK response messages is true by predefined rule Fixed, the predefined rule is at least one of：First rule, Second Rule；First rule is：The descending son Interval between first subframe corresponding to last subframe corresponding to frame/downlink information and HARQ-ACK response messages Number of sub frames meets the minimum value being more than in preset value L, i.e. last subframe corresponding to the downlink information and HARQ-ACK should It is L to answer the interval number of sub frames between first subframe corresponding to information, such as L is equal to 3；The Second Rule is：Any two The difference of HARQ-ACK response message numbers on sub-frame of uplink is less than or equal to preset value F, such as preset value F can be 2,3 or 4.
Here, first subframe corresponding to last subframe corresponding to the downlink information and HARQ-ACK response messages Between interval number of sub frames can be determined by signaling.
When actually implementing, HARQ-ACK response messages can confirm (ACK) information, non-acknowledgement (NACK) information or non- Continuously transmit (DTX) information etc..
Using the first embodiment of the sending method of ascending control information of the present invention, the UE can be made to support HARQ-ACK Binding, and then make the MTC of UE supports higher data rate application.
Second embodiment
In order to more embody the purpose of the present invention, on the basis of first embodiment of the invention, further lifted Example explanation.
In second embodiment of the invention, it is assumed that the timing relationship of the downlink information and corresponding HARQ instance-ACK response messages is Timing between the sub-frame of uplink according to where predefined rule determines S1 descending sub frame and corresponding HARQ instance-ACK response messages Relation obtains, it is assumed that maximum downstream enters the value that number of passes is 10, S1 and enters number of passes equal to maximum downstream, and preset value K is equal to 4, preset value L Equal to 3, subframe index n0Subframe be fixed subframe；When wireless frame index is even number, n0Equal to 0, when wireless frame index For odd number when, n0Equal to 5, QiEqual to 1, that is to say, that corresponding 1 sub-frame of uplink when HARQ-ACK response messages transmit, because S1 =10, preset value K=4, Qi=4, so S2=3.
Illustrate a variety of implementations of second embodiment of the invention below by specific embodiment 1 to specific embodiment 4.
