Abstract

The invention provides a feedback acquiring and transmission method and a feedback acquiring and transmission device which are suitable for the field of mobile communication. The feedback acquiring and transmission method is characterized by comprising the steps that uplink control channels of main carriers which do not belong to a certain cell are monitored, and feedback of user equipment (UE) is acquired on the uplink control channels through monitoring. Due to the increasing of the working bandwidth of a base station, the frequencies of the main carriers can be supported by the working bandwidth, the uplink control channels of the main carriers can be monitored, and therefore feedback, on the uplink control channels, of the UE is further acquired, time delay of feedback acquiring is reduced, and system efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a feedback acquisition and transmission method and a feedback acquisition and transmission device. Background technique [0002] Under the carrier aggregation technology of the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) Long Term Evolution--Advanced (LTE-A) Release 11 (Release 11, Rel 11), for the user equipment (User Equipment, UE) service carriers are also called constituent carriers, which are macro base stations (Macro eNodeB, Macro eNB) and small base stations. The small base stations can be Remote Radio Headers (RRH), forwarding Repeater (Repeater) or micro base station (Pico eNodeB, Pico eNB), etc., the above-mentioned RRH, Repeater and Pico eNB are collectively called Low Power Node (Low Power Node, LPN). [0003] In the above scenario, the current uplink control channel, such as the physical uplink control channel (P...
