Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] first, figure 1 A system scenario to which the method for obtaining feedback provided by the present invention is applicable is shown, and for convenience of description, only parts related to this embodiment are shown.

[0035] refer to figure 1 , the carriers that provide services for UE 11 are respectively from macro base station 12 and at least one LPN 13, wherein macro base station 12 is used to ensure macro coverage and create possibility for the mobility of UE 11; LPN 13 can be RRH, Repeater or PicoeNB, using Focus on hotspot coverage to improve throughput. Among the multiple diffe...

Abstract

A feedback obtaining method, comprising: monitoring an uplink control channel of a main carrier not belonging to a current cell; and obtaining, through the monitoring, a feedback of a user equipment (UE) from the uplink control channel. According to the present invention, increasing an operating bandwidth of a base station enables the operating bandwidth to support a main carrier frequency, and monitor the uplink control channel of the main carrier, so as to further obtain the feedback of the UE in the uplink control channel, thereby reducing the delay in obtaining the feedback, and improving the system efficiency.

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 component carriers, which are macro base stations (Macro eNodeB, Macro eNB) and small base stations. The small base stations can be Remote Radio Headers (RemoteRadio Header, RRH), transponders (Repeater) or micro base station (Pico eNodeB, Pico eNB), etc., the above-mentioned RRH, Repeater and Pico eNB are collectively referred to as a low power node (Low Power Node, LPN). [0003] In the above scenario, the current uplink control channel, such as the physical upli...
