The method and terminal of a kind of feedback acknowledgment information and base station
Technical field
The present invention relates to fields of communication technology, and in particular to the method and terminal of a kind of feedback acknowledgment information and base station.
Background technology
The development of the communication technology so that terminal(User Equipment, UE)It can establish and connect with more than two base stations simultaneously
It connects.For example, in long term evolution(LongTermEvolution, LTE)In the dual link scene of R12 versions, UE can simultaneously with it is macro
Base station(Macro)With small base station(Pico)Connection is established, receives the downlink data of both base stations transmission.
After terminal receives the downlink data of base station transmission, answering feedback acknowledgment information, described confirmation information includes to base station
Correct response or incorrect response(ACK/NACK, A/N).Since existing terminal can only be in a uplink band in synchronization
Upper transmission data, this is allowed for, if more than two base stations send downlink data to terminal simultaneously, terminal can only give wherein one
A base station feedback confirmation message cannot then timely feedback confirmation message for other base stations, thus can not normal communication.
In other words, although the prior art supports terminal is established simultaneously with more than two base stations to connect, it does not support
More than two base stations send downlink data to terminal simultaneously.
