    Abstract: 통신 시스템은 양쪽 업링크(UL) 송신들이 동시에 스케쥴링될 때 ACK/NACK 및/또는 서비스 요청(SR)이 수신되었는지를 사용자 장비(UE)를 스케쥴링하는 베이스 노드(base node)가 결정할 수 있도록 멀티플렉싱 방식(scheme)을 통합한다. 베이스 노드가 ACK/NACK 또는 SR UL 채널에 의해 선택적인 사용을 해석할 수 있기 때문에, 상당한 복잡성 감소, 보다 우수한 링크 효율성, 및 보다 높은 멀티플렉싱 능력이 달성된다. 상기 해석은 다중 다운링크(DL) 송신 모드들, 특히 DL 단일 입력 다중 출력(SIMO), 랭크 1 송신에 관한 DL 다중 입력 다중 출력(MIMO), 및 랭크 2 송신에 관한 DL MIMO가 사용될 때로 확장될 수 있다. 스케쥴링 및 DL 송신 모드의 지식을 기초로, 베이스 노드는 UE로부터의 가능한 응답들의 맵핑으로 인해 다수의 가능성들을 블라인드 디코딩(blind decode) 하지 않아야 한다. 게다가, 멀티플렉싱 방식은 FDD 및 TDD에 응용할 수 있다.

    Abstract: 무선통신을위한방법들, 시스템들, 및디바이스들이설명된다. 무선디바이스는프레임의각각의서브프레임에대한서브프레임구성옵션들을정의하는업링크/다운링크 (UL/DL) 구성을식별할수도있다. 예를들어, UL/DL 구성은기지국과사용자장비 (UE) 간의시간분할듀플렉싱 (TDD) 동작에대한파라미터들을확립할수도있다. 무선디바이스 (예를들어, UE 또는기지국) 는 UL/DL 구성에기초하여프레임의서브프레임에대한제약을결정하고그 후그 제약에기초하여적응적서브프레임구성을결정할수도있다. 적응적서브프레임구성은하나또는여러개의다운링크심볼주기들및 하나또는여러개의업링크심볼주기들을포함할수도있다. 무선디바이스는그 후원래의 UL/DL 구성보다는적응적서브프레임구성에따른서브프레임동안통신할수도있고; 그리고, 적응적서브프레임이식별된 UL/DL 구성에의해제약될수도있기때문에, 서브프레임동안의통신은 UE들에대한중단을회피할수도있다.

    Abstract: PROBLEM TO BE SOLVED: To enable multicarrier wireless communication systems to receive multichannel quality feedback from a plurality of user devices during legacy single carrier communication.SOLUTION: CQI reporting regions of PUCCH formats are expanded for multiple DL carriers in order to receive CQI feedback of the multiple DL carriers (602). Quality feedback of wideband carriers is reported as a CQI for all the DL carriers (604). A table defining a subband size and bandwidth parts as a function of the system bandwidth is expanded to include larger bandwidths (606). Subband CQI reporting is done beyond the defined bandwidth parts with certain periodicity (608).

    Abstract: PROBLEM TO BE SOLVED: To provide a technique for reducing overhead system information between nodes and user equipment (UE).SOLUTION: Among the carriers, it is beneficial to have some special carriers designated by configurations in order to provide synchronization, system information, paging, data and control for multi-carrier enabled UE. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UE for access, synchronization, broadcast, and new control region within data regions of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate optimal transmission of system parameter data in a wireless communication system.SOLUTION: Data is classified by determining whether the data is one of static, semi-static, and dynamic in nature. A broadcast channel is split into at least two portions. One portion allows transmission of static system parameter data at a first data rate, and a second portion allows transmission of semi-static or dynamic parameter data at a second disparate data rate.
