摘要： A transmitter directed, distributed receiver using multi-user diversity provided by the distribution of the receiver. Advantage is taken of the uncorrelated variations over time in the condition of communication links between a common transmitter and several users. The greater the variation in the quality of a particular link over time, the greater the increase in total system throughput provided. An scheduler metric (or scheduler metric) represents the instantaneous quality of the communication link between each user and the transmitter with respect to the average quality of the link. Alternatively, the scheduler metric represents the instantaneous channel condition with respect to the average data throughput over that channel. The common transmitting station uses the scheduler metric to directly compare the desirability of granting each channel access with the desirability of granting each other channel access. The users with links that have the greatest scheduler metric are provided access to the channels.

摘要： Embodiments disclosed herein relate to methods and systems for providing improved position-location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an embodiment, an access point may replace information (e.g., data) transmission by a "known" transmission (or "reference transmission") at a predetermined time known to access terminals in the corresponding sectors. The access terminals may use the received reference transmission to perform a position-location measurement, and report back the measured information. The access point may also send a reference transmission on demand, e.g., in response to a request from an access terminal in need for a location-based service.

摘要： Techniques to increase capacity in a wireless communications system. In an aspect, systematic non-transmission, or "blanking," of minimal-rate frames transmitted in a communications system is provided. In an exemplary embodiment, eighth rate frames in a cdma2000 voice communications system are systematically substituted with null-rate frames carrying zero traffic bits. Provisions are nevertheless made for the transmission of certain designated as "critical" by, e.g., a vocoder. The receiver detects the presence of null rate or non-null rate transmissions and processes the received frames accordingly, including updating an outer loop power control only in response to non-null rate frames. Further techniques for changing the pilot transmission gating pattern to assist the receiver in detecting null rate frames are provided. In another aspect, early termination of a signal transmission over a wireless communications link is provided. In an exemplary embodiment, a base station (BS) transmits power control groups (PCG's) for a frame over a forward link (FL) to a mobile station (MS) until accurate reception of the frame is acknowledged by the MS over a reverse link (RL), possibly before all PCG's of the frame are received over the FL. Possible ACK signaling methods are defined for channels associated with a cdma2000 wireless communications system. In another exemplary embodiment, techniques for reverse link early termination are also provided.
摘要翻译：提高无线通信系统容量的技术。在一方面，提供了在通信系统中传输的最小速率帧的系统非传输或“消隐”。在示例性实施例中，cdma2000语音通信系统中的第八速率帧被系统地替换为带有零业务位的零速率帧。然而，对于由例如声码器指定为“关键”的某些设备进行了规定。接收机检测到零速率或非零速率传输的存在并相应地处理接收到的帧，包括仅响应于非空速率帧来更新外部环路功率控制。提供了用于改变导频传输门控模式以辅助接收机检测零速率帧的其它技术。在另一方面，提供了通过无线通信链路的信号传输的提前终止。在示例性实施例中，基站（BS）通过前向链路（FL）向移动站（MS）发送用于帧的功率控制组（PCG），直到MS通过反向链路确认帧的准确接收（RL），可能在帧的所有PCG之前都被接收到FL。针对与cdma2000无线通信系统相关的通道定义了可能的ACK信令方法。在另一示例性实施例中，还提供了用于反向链路提前终止的技术。

摘要： Synchronized broadcast transmits a same broadcast content using a same waveform from multiple transmitters. Transmitters each apply a same spreading code for broadcast transmissions. In a spread-spectrum communication system having a time division multiplexed forward link, a synchronized broadcast transmission is inserted into a broadcast slot. One embodiment employs an Orthogonal Frequency Divisional Multiplex (OFDM) waveform for the synchronized broadcast. An OFDM receiver is then used to process the received synchronized broadcast transmission. An alternate embodiment implements a broadcast Pseudo-random Noise (PN) code for use by multiple transmitters. An equalizer is then employed to estimate the synchronized broadcast transmission.

摘要： For determining use of receive diversity in a mobile station, a control system (210 or 401) determines a demand level for use of communication resources. A transmitter (300) communicates a message indicating use of receive diversity at a mobile station based on the determined demand level. In another aspect, a receiver (200) receives a channel and determines transmit power level of the channel for being at a lower or upper transmit power level limit. The control system (210 or 401) controls receive diversity by selecting a number of receiver chains (290) based on the determined transmit power level. In another aspect, receiver (200) receives a channel and determines a channel condition of the channel and duration of the channel condition. Control system (210 or 401) controls receive diversity by selecting a number of receiver chains (290) based on the determined channel condition and the duration.

摘要： A method and apparatus for controlling the transmit power of a plurality of mobile radio units (800) transmitting to a base station (900) in a mobile radio telephone system. For each of the mobile units (800) in the system, a signal strength estimate is measured at the base station (900) based on reverse link signals sent from the mobile units (800) and received at the base station (900), wherein each signal strength estimate is associated with one of the mobile units (800). The signal strength estimate associated with each mobile unit (800) is compared to a threshold. Next, for each mobile unit (800) in the plurality of mobile units (800), if the signal strength estimate associated with the mobile unit (800) is greater than the threshold, then a power control bit having a first value is assigned to the mobile unit (800); conversely, if the signal strength estimate associated with the mobile unit is less than the threshold, then a power control bit having a second value is assigned to the mobile unit (800). A variable gain that is a function of the difference between the signal strength estimate associated with the mobile unit (800) and the threshold is next applied to each power control bit. The variable gain applied to each power control bit increases as the magnitude of the difference between the signal strength estimate associated with the mobile unit (800) and the threshold increases. Each gain-adjusted power control bit is then transmitted to the mobile units (800).
