摘要： Methods and apparatus provide for channel selection within a wireless network. A multi-channel wireless access point may select a channel for a wireless device requesting data or voice service based on the transmit times of each channel supported by the multi-channel wireless access point. The transmit times may be based on the physical rates of the devices assigned to each channel. The channel may also be selected based on the quality of service requested by the wireless device, the medium occupancy of each channel, or the number of wireless devices assigned to each channel. Alternatively the wireless device may select the channel for assignment based on channel statistics information provided by the multi-channel wireless access point. This information may be provided through one or more beacon signals, or supplied in response to a request for the information from a wireless device.

摘要： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： 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.
摘要翻译：通信系统包含复用方案，使得调度用户设备（UE）的基节点可以在同时调度两个上行链路（UL）传输时确定是否已经接收到ACK / NACK和/或服务请求（SR）。由于基节点可以解释UE对ACK / NACK或SR UL信道的选择性使用，所以显着的复杂度降低，更好的链路效率和更高的复用能力。当可以使用多个下行链路（DL）传输模式时，这种解释可以扩展到具体的DL单输入多输出（SIMO），具有秩1传输的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，基节点不必盲解码多种可能性。另外，复用方案适用于FDD和TDD。

摘要： Techniques for performing partial cyclic prefix discarding are described. A user equipment (UE) may reduce the amount of cyclic prefix to discard for the last OFDM symbol prior to a switch from data reception to data transmission. This may allow the UE to complete data reception earlier and to switch to data transmission in a timely manner. In one design, the UE may receive a first OFDM symbol and discard a first amount of cyclic prefix for the first OFDM symbol. The UE may then receive a second OFDM symbol and discard a second amount of cyclic prefix for the second OFDM symbol. The second amount of cyclic prefix to discard may be determined based on the amount of time needed to switch from data reception to data transmission, which may be dependent on the amount of time advance between transmit timing and receive timing at the UE.
摘要翻译：描述了用于执行部分循环前缀丢弃的技术。用户设备（UE）可以在从数据接收切换到数据传输之前减少最后OFDM符号丢弃的循环前缀量。这可以允许UE更早地完成数据接收并及时切换到数据传输。在一种设计中，UE可以接收第一OFDM符号并丢弃第一OFDM符号的第一量的循环前缀。 UE然后可以接收第二OFDM码元并丢弃第二OFDM码元的第二量的循环前缀。可以基于从数据接收切换到数据传输所需的时间量来确定丢弃的循环前缀的第二量，这可能取决于在UE处的发送时序与接收时序之间的时间提前量。

摘要： Techniques for sending a MIMO transmission in a wireless communication system are described. In one design, a transmitter sends a first reference signal to a receiver. The receiver selects a precoding matrix based on the first reference signal and in accordance with a selection criterion. The receiver estimates noise and interference at the receiver and determines channel quality indicator (CQI) or modulation and coding scheme (MCS) information based on the precoding matrix and the estimated noise and interference. The receiver sends the CQI or MCS information and a second reference signal to the transmitter. The transmitter selects the precoding matrix based on the second reference signal and in accordance with the same selection criterion used by the receiver. The transmitter then sends a MIMO transmission to the receiver based on the CQI or MCS information obtained from the receiver and the precoding matrix selected by the transmitter.

摘要： 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.

摘要： Techniques for sending control information in a wireless communication system are described. In an aspect, a UE spreads control information across frequency with a DFT and across time with an orthogonal sequence to obtain output data for the control information. In one design, the UE receives codewords for N HARQ processes in N downlink subframes, determines an ACK value for each HARQ process, codes N ACK values for the N HARQ processes to obtain ACK information, generates output data for the ACK information, and sends the output data in one of M uplink subframes. In another aspect, first control information is processed based on a first coding and multiplexing scheme utilizing code division multiplexing in time and frequency domains. Second control information is processed based on a second coding and multiplexing scheme utilizing code division multiplexing in time domain and spreading in frequency domain.

摘要： Techniques for performing spectral shaping to achieve a desired peak-to- average ratio (PAR) are described. Spectral shaping may be selectively performed for a single-carrier frequency division multiplexing (SC-FDM) signal based on one or more criteria, e.g., in transmit power limited conditions and/or if a modulation scheme with lower PAR is unavailable. At least one parameter of a window function or spectral shaping filter may also be adjusted based on at least one characteristic of the SC-FDM signal. For example, the roll-off of the spectral shaping filter may be adjusted based on the modulation scheme and/or the number of subcarriers used for the SC-FDM signal. A transmitter may perform spectral shaping on modulation symbols, if enabled, to obtain spectrally shaped symbols. Spectral shaping may be performed in the frequency domain either within an allocated bandwidth or with bandwidth expansion. The SC- FDM signal may be generated based on the spectrally shaped symbols.

摘要： Systems and methodologies are described that facilitate multiplexing unicast reference symbols and multicast transmissions in the same transmission time interval. In particular, mechanisms are provided that enable multiplexing unicast reference symbols to single frequency network transmissions that utilize a longer cyclic prefix duration. Unicast reference symbols are sent in a first symbol of a slot containing both unicast and single frequency network transmissions. The frequency utilized for the unicast reference symbols is staggered between the first symbol and a subsequent symbol in a sub-frame.

摘要： 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.
