    • Systems and methodologies are described that facilitate utilizing power control preambles with closed loop power control techniques in a wireless communication environment. An uplink grant can be transferred over a downlink (e.g., a first uplink grant after uplink inactivity), and a power control preamble can be sent over an uplink in response to the uplink grant. According to an example, transmission of the power control preamble can be explicitly scheduled and/or implicitly scheduled. The power control preamble can be transmitted at a power level determined by an access terminal utilizing an open loop power control mechanism. A base station can analyze the power control preamble and generate a power control command based thereupon to correct the power level employed by the access terminal. The access terminal can thereafter utilize the power control command to adjust the power level for uplink data transmission.
    • 描述了在无线通信环境中便利利用具有闭环功率控制技术的功率控制前导码的系统和方法。 可以通过下行链路(例如,上行链路不活动之后的第一上行链路许可)来传送上行链路许可,并且响应于上行链路许可,可以通过上行链路发送功率控制前导码。 根据一个示例,可以明确地调度和/或隐式调度功率控制前导码的传输。 功率控制前置码可以利用开环功率控制机制由接入终端确定的功率电平进行传输。 基站可以分析功率控制前同步码,并基于此来生成功率控制命令,以便校正接入终端所采用的功率电平。 接入终端此后可利用功率控制命令来调整上行数据传输的功率电平。

    • Techniques for supporting synchronization in wireless communication are described. A Node B generates a primary synchronization code (PSC) having a length of L chips based on a first inner sequence and a first outer sequence, where L is less than 256. The Node B also generates a sequence of secondary synchronization codes (SSCs) based on a second inner sequence and a second outer sequence, with each SSC having a length of L chips. L may be equal to 64, and the PSC and SSCs may have lengths of 64 chips. The Node B sends the PSC in each slot of each frame and sends the sequence of SSCs in each frame, one SSC in each slot. A user equipment (UE) detects for the PSC and then detects for the sequence of SSCs using slot timing from the PSC detection. The UE may perform PSC detection using correlation results for the SSCs.

    • 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.
