    • 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.
    • 通信系统包括复用方案,使得调度用户设备(UE)的基站节点可以确定当同时调度上行链路(UL)传输时是否已经接收到ACK / NACK和/或服务请求(SR)。 显着的复杂度降低,更好的链路效率和更高的复用能力,因为基站节点可以解释UE对ACK / NACK或SR UL信道的选择性使用。 这样的解释可以扩展到当可以使用多个下行链路(DL)传输模式时,具体地,具有秩1传输的DL单输入多输出(SIMO),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,基本节点不必对许多可能性进行盲解码。 另外,复用方案适用于FDD和TDD。

    • Techniques for dynamically mapping assigned resources to physical resources are described herein. In one design, a resource assigned for communication may be mapped to a first physical resource based on a first mapping function and to a second physical resource based on a second mapping function. The assigned resource may be configurable for hopping or no hopping. The first mapping function may be a transparent function or may map consecutive input indices to non-consecutive output indices. The second mapping function may be equal to an output of the first mapping function plus an offset defined by a step size and a hop value. The hop value may be configurable for the assigned resource and may be conveyed in a resource assignment. The hop value may be set to a first value to indicate no hopping or to a second value to indicate hopping by the step size.
    • 本文描述了将分配的资源动态地映射到物理资源的技术。 在一种设计中,分配给通信的资源可以基于第一映射函数被映射到第一物理资源,并且可以基于第二映射函数映射到第二物理资源。 分配的资源可以被配置用于跳频或不跳频。 第一映射函数可以是透明函数,或者将连续输入索引映射到非连续输出索引。 第二映射函数可以等于第一映射函数的输出加上由步长和跳数定义的偏移量。 该跳值可以针对所分配的资源是可配置的,并且可以在资源分配中传送。 可以将跳值设置为第一值以指示不跳频或者指示第二值以指示通过步长的跳跃。

    • Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.

    • Systems and methodologies are described that facilitate efficiently indicating parameter(s) associated with a base station utilizing synchronization signals in a wireless communication environment. For instance, relative locations of a PSC and a SSC in a radio frame can be a function of a parameter. Further, a PSC sequence utilized to generate PSCs can be selected based upon a parameter. Moreover, inclusion or exclusion of PSCs from a radio frame can be a function of a parameter. Additionally or alternatively, pseudo random sequence mappings (e.g., to cell IDs, tone locations) can be a function of a parameter. Example parameters can be whether the base station is part of a TDD or a FDD system, whether the radio frame employs FS1 or FS2, whether the base station is associated with a macro or a femto cell, or whether the base station is associated with a unicast or a multicast system.
