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： A method for processing forward link channel signals generated by a CDMA base station includes time sharing by several mobile stations of spreading codes, which are orthogonal codes such as Walsh Code, and code-combining soft/softer handoff across sectors in the mobile station active set to increase dimensions on the CDMA2000 and WCDMA downlink while minimizing intra-sector interference. Since different parts of a packet or frame are transmitted to the user by the different base stations in the active set, earlier decoding and therefore early packet termination is enabled.

摘要： A control channel in a communication system transmits messages in a one or multiple-slot format. To assure consistency of a message, a content quality indicator is included in the message. Because a terminal receiving the message does not know the number of slots comprising the message, the terminal performs blind format determination by testing hypothesis for all slot formats. Unfortunately, the content of certain control messages results in control messages that appear to be valid in a sense that, the computed CRC is equal to the interpreted CRC. Consequently, the mobile station declares a valid control message, and a false-alarm event occurs. Moreover, the same control messages always result in the same false-alarm events. To prevent such repetitive incorrect determination, the content of the message is scrambled by a time-dependent scrambling sequence before transmission. Re-generating the scrambling sequence, and performing inverse to the scrambling then unscrambles the received message.
摘要翻译： 通信系统中的控制信道以一个或多个时隙格式发送消息。 为了确保消息的一致性，消息中包含内容质量指示符。 由于接收到该消息的终端不知道包含消息的时隙数，所以终端通过针对所有时隙格式的假设进行盲格式确定。 不幸的是，某些控制消息的内容导致控制消息看起来是有效的，因为所计算的CRC等于解释的CRC。 因此，移动台宣布有效的控制消息，并发生假警报事件。 此外，相同的控制消息总是导致相同的假警报事件。 为了防止这种重复的错误确定，在发送之前，通过时间相关的加扰序列对消息的内容进行加扰。 重新生成加扰序列，并且对加扰进行反相，然后解扰接收到的消息。

摘要： A method and apparatus for adaptively controlling the power level of transmissions from a remote station by determining the velocity of the remote station. A general classification of the velocity of the remote station can be used to selectively implement a closed loop power control scheme. Power level parameters are used to determine velocity. In accordance with a classification of stationary, low speed, or high speed, the closed loop power control is selectively operated. Velocity can be determined by either the base station or the remote station through various methods. One method is the use of power control bits and/or average power to determine level crossings and excursion times.

摘要： Independently controlling the transmitted power of each subchannel by a subchannel control loop is described. A transmitting station generates a channel made up of a sum of subchannels wherein each subchannel or group of subchannels is amplified with a unique gain value that is varied in accordance with subchannel power control messages from the receiving station. The receiving station generates each subchannel power control message subsequent to monitoring and calculating metrics based on that received subchannel.
