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.

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.

PROBLEM TO BE SOLVED: To provide a method of sending grant information to mobile devices having single carrier capabilities and/or mobile devices having multicarrier capabilities in a multicarrier wireless communication system.SOLUTION: A method for transmitting grant information comprises: determining grant information including at least resource information to be used; identifying a control region to communicate the grant information as a function of user device capabilities; inserting the grant information in the identified control region; and transmitting the grant information in the identified control region. The grant information can be sent in a legacy control region and/or a non-legacy control region.
Abstract:
PROBLEM TO BE SOLVED: To provide techniques to support operation of user equipment (UE) in a compressed mode and a CPC mode.SOLUTION: The UE may obtain assignment of enabled subframes for the CPC mode and assignment of transmission gaps for the compressed mode. The transmission gaps may be aligned with idle times between the enabled subframes. The UE may exchange data during enabled subframes not overlapping the transmission gaps and may skip data exchanges during enabled subframes overlapping the transmission gaps. The UE may make cell measurement during the transmission gaps. The UE may obtain enabled subframes and skipped subframes, exchange data during enabled subframes not corresponding to the skipped subframes, and skip data exchanges during the skipped subframes. The UE may receive orders on a shared control channel to quickly enable and disable the compressed mode.
Abstract:
PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate assigning resources for an anchor carrier and an additional carrier with a grant message.SOLUTION: The grant message communicated with an anchor carrier can include resource information for a plurality of carriers. The systems and methodologies facilitate identifying control information for an anchor carrier and/or an additional carrier on the basis of an operating mode. The operating mode is a legacy mode or an extended mode (1102). On the basis of the operating mode, particular resources associated with control regions are monitored for control information for respective anchor carrier(s) or additional carrier(s) (1104).
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.
