    • Systems and methodologies are described that facilitate simultaneous transmission of control information in a single sub-frame. For instance, simultaneous transmission can maintain single carrier waveforms for a control channel even when a plurality of information types is scheduled in concurrently. Channel quality indicators, scheduling requests and acknowledgement messages can be jointly coded. In addition, reference symbols in a sub-frame can be modulated to indicate values associated with a scheduling request or an acknowledgement message. Moreover, in situations where channel quality indicators, scheduling requests and or acknowledgement messages are simultaneously scheduled, one or more can be dropped. Further, a single carrier constraint can be relaxed to enable simultaneous transmission of information in the sub-frame at different frequencies.
    • 描述了便于在单个子帧中同时传输控制信息的系统和方法。 例如,即使当并行调度多个信息类型时,同时传输也可以保持用于控制信道的单载波波形。 信道质量指示符,调度请求和确认消息可以被联合编码。 此外,子帧中的参考符号可以被调制以指示与调度请求或确认消息相关联的值。 此外,在同时调度信道质量指示符,调度请求和确认消息的情况下,可以丢弃一个或多个。 此外,可以放宽单载波约束以使得能够以不同频率在子帧中同时传输信息。

    • Techniques for sending control information in a wireless communication system are described. In an aspect, a user equipment (UE) may send data for control information in a resource block with frequency division multiplexing (FDM) and may send pilot in the resource block with frequency-domain code division multiplexing (CDM). The UE may determine multiple groups of subcarriers to use to send data in multiple symbol periods of the resource block based on a predetermined pattern or a pseudo-random hopping pattern. Each group may include consecutive subcarriers to support localized FDM. The multiple groups may include different subcarriers to provide frequency diversity and possibly interference averaging. The UE may send modulation symbols for data (e.g., in the time domain) on the multiple groups of subcarriers in the multiple symbol periods. The UE may send a reference signal sequence for pilot on multiple subcarriers in each symbol period for pilot.
    • 描述用于在无线通信系统中发送控制信息的技术。 一方面,用户设备(UE)可以通过频分复用(FDM)在资源块中发送用于控制信息的数据,并且可以使用频域码分复用(CDM)在资源块中发送导频。 UE可以基于预定模式或伪随机跳频模式来确定用于在资源块的多个符号周期中发送数据的多个子载波组。 每个组可以包括连续的子载波以支持本地化的FDM。 多个组可以包括不同的子载波以提供频率分集和可能的干扰平均。 UE可以在多个符号周期中的多个子载波组上发送用于数据(例如,在时域中)的调制符号。 UE可以在用于导频的每个符号周期中在多个子载波上发送用于导频的参考信号序列。

    • Techniques for sending control information in a wireless communication system are described. In one design, a user equipment (UE) may map first information (e.g., CQI information) to M most significant bits (MSBs) of a message and may map second information (e.g., ACK information) to N least significant bits (LSBs) of the message if the second information is sent, where M = 1 and N = 1. The UE may encode the message with a block code, e.g., encode the M MSBs with the first M basis sequences of the block code and encode the N LSBs with the next N basis sequences of the block code. The second information may include N ACK bits. The UE may set each ACK bit to a first value for an ACK or to a second value for a NACK. The second value may also be used for discontinuous transmission (DTX) of ACK information.

    • A transmitter in a wireless network transmits joint channel quality indicator (CQI) and data packet acknowledgement (Ack) or just CQI within the same subframe without uplink data transmission that can be readily detected at a receiver. When a short cyclic prefix (CP) is appropriate, a first approach utilizes a pilot aided signaling by using two different Walsh covers for the pilots to signal CQI vs. CQI+ACK. When a long CP is appropriate with one pilot, two different code designs are provided for CQI and CQI+ACK that only optimize the code book for each mode separately, but also maximize the distance between these two code spaces. Various coset based approaches are described to search for such linear block codes. Initial results showed good codes can be found based on the coset based approach to minimize the false alarm and misdetection.
    • 无线网络中的发射机在同一子帧内发送联合信道质量指示符(CQI)和数据分组确认(Ack)或仅发送CQI,而无需在接收机处容易地检测到上行链路数据传输。 当短循环前缀(CP)适当时,第一种方法利用导频辅助信令,通过使用两个不同的沃尔什覆盖用于导频信号CQI与CQI + ACK。 当长的CP适合于一个导频时,为CQI和CQI + ACK提供两种不同的代码设计,其仅针对每个模式分别优化代码簿,而且最大化这两个代码空间之间的距离。 描述了各种基于陪集的方法来搜索这种线性块码。 初步结果表明,基于陪集方法可以找到良好的代码,以尽量减少误报和误检。
