摘要： A disclosed code-division-multiple-access (CDMA) system has a base station (BS) and remote stations (RSs). A BS-spread-spectrum transmitter broadcasts a common-synchronization channel having a chip-sequence signal common to the remote stations served by the BS, and a frame-timing signal. A RS-spread-spectrum receiver receives the broadcast common-synchronization channel, and determines frame timing from the frame-timing signal. A first RS-spread-spectrum transmitter transmits an access-burst signal, which has a plurality of segments. Each access burst signal segment has a plurality of power levels. A BS-spread-spectrum receiver receives the access-burst signal at a detected-power level. In response to receiving the access-burst signal, a BS-spread-spectrum transmitter transmits an acknowledgment signal to the RS-spread-spectrum receiver. The RS-spread-spectrum receiver receives the acknowledgment signal, and in, the RS-spread-spectrum transmitter transmits a spread-spectrum signal having data to the BS-spread-spectrum receiver.

摘要： An access point device and access point system support wireless and/or wired communications. The access point includes temperature control functionality that is adapted to control/moderate the temperature within an access point. The temperature control functionality may operate to control the transmit power, the throughput or other operating parameters associated with the access point. The temperature control functionality may also actuate a cooling mechanism, e.g., a fan, associated with the access point. Load balancing may also be employed to reduce heat generation associated with an access point. The temperature control functionality may reside at the access point, e.g., a “fat” access point, or may reside at the wireless controller, e.g., a “thin” access point. Error voltage signals may also be generated and transmitted to a TCVCXO to control or moderate temperature conditions and heat generation.

摘要： Embodiments provide techniques for power control. For instance, a method exchanges one or more transmissions with a remote device in accordance with a retransmission protocol. In addition, a power control message is exchanged with the remote device through at least one of the one or more transmissions. Thus, closed loop power control may be performed through retransmission protocol communications.
