摘要： A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

摘要： Systems and methodologies are described that facilitate utilizing different power control algorithms as a function of access terminal speed. For instance, instantaneous Channel Quality Indicator (CQI) reports can be inverted for slow moving access terminals while long-term geometry inversion (e.g., average CQI report inversion) can be utilized for quick moving access terminals. Speed of the access terminal can be estimated based upon time correlation of CQI values. Further, selection of implementing instantaneous CQI inversion or long-term geometry inversion can be based upon the estimated speed of the access terminal.

摘要： Techniques for supporting communication in dominant interference scenarios are described. In an aspect, communication in a dominant interference scenario may be supported with cross-subframe control. Different base stations may be allocated different subframes for sending control information. Each base station may send control messages in the subframes allocated to that base station. Different base stations may have different timelines for sending control messages due to their different allocated subframes. With cross-subframe control, control information (e.g., grants, acknowledgement, etc.) may be sent in a first subframe and may be applicable for data transmission in a second subframe, which may be a variable number of subframes from the first subframe. In another aspect, messages to mitigate interference may be sent on a physical downlink control channel (PDCCH).

摘要： Systems and methodologies are described that facilitate mitigating intercarrier and intersymbol interference in symbol transmissions over wireless communications where transmitter and receiver may not be time synchronized. Symbol periods can be extended for transmitting symbols such that an original symbol can be transmitted with one or more duplicated symbols keeping phase continuous, blank symbols, and/or the like. In this regard, multiple receiver windows can be required to receive the symbol such that at least one window has a non-interfered symbol even though timing can be misaligned (e.g., in asynchronous communications channels). Alternatively, the receiver windows can be divided to allow similar receipt of symbols over multiple windows such that one window has a non-interfered symbol. Also, timing misalignment that leads to phase ramping in frequency is accounted for to allow proper demodulation of the symbol.
摘要翻译：描述了系统和方法，其有助于减轻发射机和接收机可能不是时间同步的无线通信中的符号传输中的载波间和符号间干扰。可以扩展符号周期以发送符号，使得可以用保持相位连续，空白符号等的一个或多个复制符号来发送原始符号。在这方面，可能需要多个接收机窗口来接收符号，使得即使定时可能未对准（例如，在异步通信信道中），至少一个窗口具有非干扰符号。或者，接收器窗口可以被划分以允许在多个窗口上类似地接收符号，使得一个窗口具有非干扰符号。此外，导致频率相位斜变的定时未对准被认为是允许符号的适当解调。

摘要： Systems and methodologies are described that facilitate improved resource partitioning and interference management in a wireless communication system. Techniques are described herein for the transmission and use of various types of signaling, such as Access Request commands, Reverse Link Special Resource Utilization Message (R-SRUM) signaling, Forward Link Special Resource Utilization Message (F-SRUM) signaling, and the like, for managing interference associated with range extension, restricted association networks, and other jamming scenarios. As described herein, downlink resource coordination and interference management are accomplished through the use of Access Request or R-SRUM signaling conducted in a unicast or broadcast fashion, and uplink resource coordination and interference management are accomplished through the use of F-SRUM signaling. As further described herein, a clean communication channel such as a Low Reuse Preamble (LRP) channel can be utilized for interference management signaling and/or leveraged for determining timing of various signaling messages.

摘要： Techniques for sending signaling messages with beacon signals in a wireless communication network are described. In one design, a transmitter station may map a signaling message (e.g., a reduce interference request) to multiple code symbols. The transmitter station may select multiple resource elements from among a plurality of resource elements based on the multiple code symbols. In one design, each code symbol may be sent across frequency by selecting one of multiple subcarriers in one symbol period. In another design, each code symbol may be sent across time by selecting one of multiple symbol periods on one subcarrier. The transmitter station may generate a beacon signal having transmit power on the selected resource elements and no transmit power on remaining resource elements. The transmitter station may send the beacon signal to at least one receiver station.
