    • Systems and methodologies are described that facilitate signaling and detecting discontinuous transmission (DTX) in a wireless communication environment. A DTX indicator and Channel Quality Indicator (CQI) feedback can be multiplexed within a common uplink control channel subframe and transmitted to a base station when the access terminal is operating in DTX mode for an Acknowledgement Channel. Further, when operating in non-DTX mode, the access terminal can multiplex an ACK indicator or a NAK indicator with the CQI feedback within a common uplink control channel subframe, which can thereafter be transferred to the base station. Accordingly, the base station can detect DTX operation or non-DTX operation of the access terminal. For example, reference signal symbols can carry one of the DTX indicator, the ACK indicator, or the NAK indicator. Pursuant to another example, the CQI feedback and the DTX indicator can be combined and carried jointly by non-reference signal symbols.
    • 描述了在无线通信环境中促进信令和检测不连续传输(DTX)的系统和方法。 DTX指示符和信道质量指示符(CQI)反馈可以在公共上行链路控制信道子帧内多路复用,并且当接入终端以确认信道的DTX模式工作时被发送到基站。 此外,当在非DTX模式下操作时,接入终端可以在公共上行链路控制信道子帧内将ACK指示符或NAK指示符与CQI反馈复用,然后可以将其传送到基站。 因此,基站可以检测接入终端的DTX操作或非DTX操作。 例如,参考信号符号可以携带DTX指示符,ACK指示符或NAK指示符之一。 根据另一示例,CQI反馈和DTX指示符可以由非参考信号符号组合和携带。

    • A communication system incorporates a multiplexing scheme so that a base node that schedules user equipment (UE) can determine whether an ACK/NACK and/or a service request (SR) has been received when both uplink (UL) transmissions are simultaneously scheduled. Significant complexity reduction, better link efficiency, and higher multiplexing capability since the base node can interpret selective use by the UE of either the ACK/NACK or SR UL channel. Such interpretation can be extended to when multiple downlink (DL) transmission modes can be used, specifically DL single input multiple output (SIMO), DL multiple input multiple output (MIMO) with rank 1 transmission, and DL MIMO with rank 2 transmission. Based upon knowledge of the scheduling and DL transmission mode, the base node does not have to blind decode a number of possibilities due to the mapping of possible responses from the UE. In addition, the multiplexing scheme is applicable to FDD and TDD.
    • 通信系统包含复用方案,使得调度用户设备(UE)的基节点可以在同时调度两个上行链路(UL)传输时确定是否已经接收到ACK / NACK和/或服务请求(SR)。 由于基节点可以解释UE对ACK / NACK或SR UL信道的选择性使用,所以显着的复杂度降低,更好的链路效率和更高的复用能力。 当可以使用多个下行链路(DL)传输模式时,这种解释可以扩展到具体的DL单输入多输出(SIMO),具有秩1传输的DL多输入多输出(MIMO)和具有秩2传输的DL MIMO。 基于调度和DL传输模式的知识,由于来自UE的可能响应的映射,基节点不必盲解码多种可能性。 另外,复用方案适用于FDD和TDD。

    • Techniques for transmitting beacon signals to assist user equipments (UEs) perform cell search and techniques for detecting for beacon signals are described. In an aspect, cells may be assigned beacon patterns defined based on orthogonal grouping of subcarriers. U subcarriers usable for beacon may be arranged into G orthogonal groups, with each group including S subcarriers. different beacon patterns may be defined based on the G groups of S subcarriers. In another aspect, the cells may transmit their beacon signals at configurable transmit power levels, which may be determined based on target beacon detection performance. In yet another aspect, a UE may perform overlapping DFTs in order to capture more received power when symbol timing at the UE is not aligned with symbol timing of cells being detected. In yet another aspect, the UE may perform beacon detection with maximal likelihood decoding.
    • 描述了用于发送信标信号以辅助用户设备(UE)执行小区搜索的技术以及用于检测信标信号的技术。 在一个方面,小区可以被分配基于子载波的正交分组定义的信标模式。 可用于信标的U个副载波可以被布置成G个正交组,每个组包括S个副载波。 可以基于G个子载波组来定义不同的信标模式。 在另一方面,小区可以以可配置的发射功率电平来发送它们的信标信号,这可以基于目标信标检测性能来确定。 在又一个方面中,UE可以执行重叠DFT以便当在UE处的符号定时不与被检测到的小区的符号定时对齐时捕获更多的接收功率。 在又一方面中,UE可以利用最大似然解码来执行信标检测。
