摘要： A method and apparatus for providing orthogonal spot beams (14a, 14b), sectors (16a, 16b), and picocells (18), by using orthogonal auxiliary pilots and different Walsh traffic channels in adjacent areas. According to the IS-95 standard, the pilot signal is covered with the 64-chip Walsh sequence zero. Designating the 64-chip all zeros Walsh sequence as P and the 64-chip all one sequence as M, additional pilot signals are provided in the present invention by concatenating the P and the M sequences. Thus, for two pilot signals, pilot Walsh sequences of PP and PM can be used. For four pilot signals, pilot Walsh sequences of PPPP, PMPM, PPMM, and PMMP can be used. In general, the required number of pilot Walsh sequences can be generated by substituting each bit in an K-bit Walsh sequence with the 64-chip all zeros P or all ones M sequence, depending on the value of that bit.

摘要： A method and apparatus for providing diversity transmissions to a mobile unit from a transmitting station having at least first and second antennas by repeatedly switching between the two antennas during the transmission of information to the receiving unit. Message information is transmitted from the first antenna in the transmitting station to the receiving unit. After the start of the transmission of the message information from the first antenna, transmission of the message information from the first antenna to the receiving unit terminates and transmission of the message information from the second antenna in the transmitting station to the receiving unit is initiated. Some time after transmission of the message information from second antenna is initiated, the transmission of the message information from the second antenna to the receiving unit terminates and transmission of the message information from the first antenna in the transmitting station to the receiving unit is initiated. Repeated switching between the first and second antennas is achieved by repeating the process. The switching results in diversity transmissions that improve the ability of a receiving unit to receive the coded and interleaved transmitted message information from the transmitting station. The interleaver disperses the encoded symbols in each antenna dwell period such that the decoder decisions are based on a mix of symbols form each antenna. Therefore the decoder decisions are unreliable only when the mix of symbols from the different antennas, with different fading characteristics, are unreliable over the span of symbols the decoder uses in its decision process.
摘要翻译：一种用于在具有至少第一和第二天线的发射台向移动单元提供分集传输的方法和装置，通过在向接收单元发送信息期间在两个天线之间重复切换。消息信息从发送站中的第一天线发送到接收单元。在从第一天线发送消息信息开始之后，消息信息从第一天线到接收单元的传输终止，并且发送消息信息从发送站中的第二天线到接收单元的发送。开始从第二天线发送消息信息之后的某个时间，消息信息从第二天线到接收单元的传输终止，并且发送消息信息从发送站中的第一天线到接收单元的发送。通过重复该过程来实现第一和第二天线之间的重复切换。切换导致分集传输，其提高接收单元从发射台接收编码和交织的传输消息信息的能力。交织器在每个天线驻留周期中分散编码符号，使得解码器判定基于每个天线的符号混合。因此，只有当解码器在其决策过程中使用的符号范围内，来自具有不同衰落特性的不同天线的符号混合不可靠时，解码器判决才是不可靠的。

摘要： Methods and apparatus are presented to select optimal transmission formats for transmissions to a single user or simultaneous transmissions to multiple users. Priority information and channel state information associated with each user are used to determine the optimal transmit formats. In particular, said formation is used to maximize a given revenue function that enhances system throughput while maintaining fairness among users. Once transmit formats are determined, any unallocated system resources, such as unused Walsh codes or transmission power, can be evenly or proportionately distributed among the users.

摘要： In a wireless communication system a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers indicating a target recipient of packet data. The message also identifies the transmission channels used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.

摘要： Methods and apparatus are presented for improving the feedback of channel information to a serving base station, which allows a reduction in the reverse link load while allowing the base station to improve the forward link data throughput. Over a channel quality indicator channel, a carrier-to-interference (C/I) symbol is transmitted over multiple slots at a reduced rate, which increases the likelihood that the base station can decode said symbol. The reduced rate mode can be selectively triggered by a high velocity condition or other unfavorable channel condition. The C/I symbol is used to determine transmission formats, power levels, and data rates of forward link transmissions.
