    • Techniques for supporting distributed MIMO are described. For multi-user distributed MIMO, a cell directs its transmit power toward a UE while reducing interference to UE(s) in neighbor cell(s). For single-user distributed MIMO, multiple cells concurrently send transmissions to a UE. In an aspect, a UE sends channel estimates for serving and non-serving cells to support multi-user distributed MIMO. Each cell may use the channel estimates to select UEs for data transmission and determine precoding vectors to use for data transmission to the selected UEs. In another aspect, a UE sends CQI information for serving and non-serving cells to support single-user distributed MIMO. Each cell may use the CQI information to select UEs for data transmission and determine modulation and coding schemes to use for the selected UEs. In yet another aspect, a UE determines CQI information for a serving cell by taking into account interference nulling by non-serving cells.
    • 描述了支持分布式MIMO的技术。 对于多用户分布式MIMO,小区将其发射功率指向UE,同时减少对相邻小区中的UE的干扰。 对于单用户分布式MIMO,多个小区同时向UE发送传输。 在一方面,UE为服务小区和非服务小区发送信道估计以支持多用户分布式MIMO。 每个小区可以使用信道估计来选择用于数据传输的UE,并且确定用于向选择的UE进行数据传输的预编码向量。 另一方面,UE为服务小区和非服务小区发送CQI信息以支持单用户分布式MIMO。 每个小区可以使用CQI信息来选择用于数据传输的UE,并且确定用于所选择的UE的调制和编码方案。 在另一方面,UE通过考虑非服务小区的干扰归零来确定服务小区的CQI信息。

    • 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。

    • 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.
    • 这里描述了将分配的资源动态映射到物理资源的技术。 在一种设计中,分配用于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基于第二映射函数被映射到第二物理资源。 分配的资源可以配置为跳频或不跳频。 第一映射函数可以是透明函数或者可以将连续的输入索引映射到非连续的输出索引。 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跃值定义的偏移量。 跳数值可以针对分配的资源进行配置,并且可以在资源分配中传送。 跳跃值可以被设置为第一值以指示没有跳跃或者第二值以指示通过步长跳跃。

    • Techniques for performing power control during discontinuous transmission (DTX) operation are described. A UE transmits on the uplink during a transmission burst and receives TPC commands generated by a Node B based on the uplink transmission. The UE may receive two TPC commands at the end of the transmission burst that are not applied during the transmission burst. The UE saves and applies these two TPC commands in the next transmission burst. In one design, the UE applies each saved TPC command in one slot of the next transmission burst. In another design, the UE combines the two saved TPC commands and applies the combined value in the first two slots of the next transmission burst. In yet another design, the UE selects one of the saved TPC commands and applies the selected TPC command in the first two slots of the next transmission burst.
    • 描述了在不连续传输(DTX)操作期间执行功率控制的技术。 UE在传输突发期间在上行链路上进行发送,并且基于上行链路传输接收由节点B生成的TPC命令。 UE可以在传输突发结束时接收两个在传输突发期间不被应用的TPC命令。 UE在下一个传输突发中保存并应用这两个TPC命令。 在一种设计中,UE将每个保存的TPC命令应用于下一个传输突发的一个时隙。 在另一种设计中,UE组合了两个保存的TPC命令,并将组合值应用于下一个传输脉冲串的前两个时隙。 在另一种设计中,UE选择保存的TPC命令之一,并将所选择的TPC命令应用于下一个传输脉冲串的前两个时隙。
