Description

Method, user equipment and the base station of information transmission

Technical field

Machine to machine (Machine to Machine, M2M), i.e. machine-to-machine communication, mainly study how on mobile communications network carrier working application.For mobile communications network, this communication service that it is undertaken is known as machine type communication (Machine Type Communication, MTC).Introducing for MTC device needs to optimize mobile communications network or enhance.The bandwidth of operation of equipment can be reduced on the direction for reducing MTC device cost, for example limits its bandwidth of operation as 1.4MHz；In terms of coverage enhancement (coverage enhancement, CE), supported for coverage enhancement is provided in the biggish MTC device of the path losses such as basement, so that above equipment has access to network and serviced.Signal repeats to be one of the method for realizing coverage enhancement.But, environment locating for different MTC devices is different, and coverage enhancement demand is also different.If definition coverage enhancement demand size is coverage enhancement grade (CE level), environment locating for different MTC devices is different, and the coverage enhancement grade of these MTC devices is also different.Equally by taking signal repeats as an example, it is also different that the different MTC device of coverage enhancement grade needs to carry out the duplicate number of signal.

Since the bandwidth of operation of MTC device is relatively narrow, when system bandwidth is greater than the bandwidth of operation that MTC device is supported, traditional control channel, such as Physical Downlink Control Channel (Physical Downlink Control Channel,) and physical mixed automatic re-transmission indicating channel (Physical Hybrid ARQ Indicator Channel PDCCH, PHICH), it is possible to cannot be received by MTC device.So, the uplink/downlink data of MTC device or physically/DSCH Downlink Shared Channel (Physical Uplink/Downlink Shared Channel, PU/DSCH transmission), if based on control channel scheduling, so that it may use the control channel for MTC device scheduling.For transmission confirmation (the i.e. transmission shape of PUSCH State feedback), confirmation (acknowledgement, ACK)/deny (negative acknowledgement, NACK), it is necessary to which new design scheme is realized.

Pass through the Downlink Control Information of the control channel for dispatching MTC device (Downlink Control Information in the prior art, DCI ACK/NACK function is realized in the new data instruction (New Data Indicator, NDI) (0 or 1) in).Since each DCI contains multiple bits (bit), and user equipment (User Equipment, UE) only needs to read NDI, thus leads to the wasting of resources.The above-mentioned wasting of resources, under coverage enhancement scene, especially seriously, because the control channel of scheduling MTC device is also required to be repeated as many times.So the transmission confirmation of upstream data is a problem to be solved under narrowband and/or coverage enhancement scene.
