摘要： An apparatus for data communication that receives a plurality of pulses from a remote communications device, determines a pulse puncturing rate based on the pulses, and punctures or discards subsequent pulses based on the pulse puncturing rate. During intervals when punctured pulses are expected, the apparatus operates in a lower power consumption mode for the purpose of conserving power. In another aspect, a receiving apparatus determines the pulse puncturing rate based on received pulses, and transmits the pulse puncturing rate information to a transmitting apparatus. In response, the transmitting apparatus sends a subset of the pulses it would have transmitted based on the pulse puncturing rate. Because the receiving apparatus receives fewer pulses (e.g., a subset), the receiving apparatus may operate in a lower power consumption mode for longer periods in order to conserve power. Similarly, because the transmitting apparatus sends fewer pulses, it may also operate in a lower power consumption mode for longer periods.
摘要翻译：一种用于从远程通信设备接收多个脉冲的数据通信装置，基于脉冲确定脉冲打孔速率，并且基于脉冲打孔速率对后续脉冲进行穿刺或丢弃。在期望脉冲脉冲的间隔期间，为了节省功率，该装置以较低的功耗模式工作。在另一方面，接收装置基于接收到的脉冲来确定脉冲打孔速率，并将脉冲打孔速率信息发送到发送装置。作为响应，发送装置基于脉冲打孔速率发送其将发送的脉冲的子集。由于接收装置接收到更少的脉冲（例如，子集），所以接收装置可以在较低的功耗模式下操作更长的时间段，以便节省功率。类似地，由于发送装置发送较少的脉冲，所以它也可以在较低的功耗模式下工作较长时间。

摘要： Timing acquisition may be performed without typical correlation computations by determining a power of a received signal at certain points in time and using the determined power to identify gaps in the received signal. By determining gaps in the received signal, frame timing may be estimated, particularly in time-division networks where the location of guard periods within a frame is known. Gap detection may thus be used for timing acquisition.

摘要： Methods and apparatus for selecting a serving sector in a high rate data (HDR) communication system are disclosed. An exemplary HDR communication system defines a set of data rates, at which a sector of an Access Point may send data packets to an Access Terminal. The sector is selected by the Access Terminal to achieve the highest data throughput while maintaining a targeted packet error rate. The Access Terminal employs various methods to evaluate quality metrics of forward and reverse links from and to different sectors, and uses the quality metrics to select the sector to send data packets to the Access Terminal.

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： Briefly, in accordance with one embodiment, a method of adjusting for digital automatic gain control (DAGC) quantization error in a mobile station is as follows. A first DAGC value is stored before reception of one or more enhanced pilot signals. A second DAGC value is computed during reception of the one or more enhanced pilot signal. The first DAGC value is restored after reception of the one or more enhanced pilot signals is over. An advantage associated with this particular embodiment may include reduction in quantization error for digital automatic gain control.
