摘要： Techniques for transmitting synchronization signals to assist user equipments (UEs) perform cell searches are described. In one design, a base station for a cell may generate and transmit a primary synchronization signal and a secondary synchronization signal, which may be used by the UEs for initial cell search at power up. The base station may also generate and transmit one or more beacon signals, which may be used by the UEs for neighbor cell search to detect for neighbor cells. The number of beacon signals to transmit and the set of subcarriers usable for each beacon signal may be determined based on the system bandwidth. Each beacon signal may be mapped to one subcarrier in the set of subcarriers in each beacon symbol period. This one subcarrier may be determined based on a beacon hopping pattern or a beacon code and may be dependent on a cell identifier (ID).

摘要： Multi-carrier point-to-multi-point CDMA system implementation reduces hardware changes in legacy single-carrier systems. The number of common downlink channels, such as timing/synchronization and paging channels, is reduced by designating an anchor carrier for transmitting these channels. Procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signaling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimize changes in asymmetric systems with different numbers of uplink and downlink carriers. Channel Quality Indicator (CQI) field is divided into multiple subfields to enable transmission of multiple CQIs and ACK/NACK indicators on one uplink carrier. Joint and separate scheduling schemes are shown for concurrent scheduling of a data stream transmission to a UE via multiple downlink carriers.

摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

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 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： 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.

摘要： 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.

摘要： Techniques for transmitting data and pilot for control information are described. In one aspect, a user equipment (UE) may spread a reference signal sequence with a first orthogonal sequence to obtain multiple pilot sequences. The UE may then send the multiple pilot sequences on multiple subcarriers in multiple symbol periods, one pilot sequence in each symbol period. The UE may modulate the reference signal sequence with control information (e.g., ACK information) to obtain a modulated sequence. The UE may spread the modulated sequence with a second orthogonal sequence to obtain multiple data sequences. The UE may then send the multiple data sequences on the multiple subcarriers in multiple symbol periods for data. In another aspect, the UE may send multiple pilot sequences on multiple subcarriers in multiple symbol periods separated by at least one symbol period, one pilot sequence in each symbol period.
