Method and an apparatus for providing channel quality information in a wireless communication system
Patent number: 9722749Abstract: A method for transmitting channel quality information for a downlink channel; a user equipment (UE) therefore; a method for receiving channel quality information for a downlink channel; and a base station therefore are discussed. The method for transmitting channel quality information for a downlink channel includes according to one embodiment receiving, by a user equipment (UE), configuration information on periodic channel state information (CSI) reporting by higher layer signaling; determining, by the UE, a channel quality information index at least based on a number of a specific resource element; and transmitting the determined channel quality information index to a base station. The number of the specific resource element is determined based on a UE-specific reference signal overhead. A resource element allocated for a Channel Status Information-Reference Signal (CSI-RS) is regarded as the specific resource element regardless of transmitting the CSI-RS.Type: GrantFiled: February 19, 2016Date of Patent: August 1, 2017Assignee: LG ELECTRONICS INC.Inventors: In Kwon Seo, Dae Won Lee, Ki Jun Kim -

Patent number: 9722752Abstract: A method is provided for receiving a sounding reference signal (SRS) in a wireless communication system. A base station transmits downlink control information to a user equipment at a first serving cell of the plurality of serving cells. The downlink control information includes a carrier indicator and a downlink assignment. When the downlink control information includes an aperiodic SRS request that indicates a triggering of an SRS transmission, the base station receives an SRS from the user equipment at the second serving cell. If the first serving cell is a frequency division duplex (FDD) and the second serving cell is a time division duplex (TDD) cell, the downlink control information includes the aperiodic SRS request. If the first serving cell is the TDD cell and the second serving cell is the FDD cell, the downlink control information does not include the aperiodic SRS request.Type: GrantFiled: September 6, 2016Date of Patent: August 1, 2017Assignee: LG Electronics Inc.Inventors: Joonkui Ahn, Dongyoun Seo, Suckchel Yang
