Abstract: A system and method are disclosed for decreasing the amount of power consumed by a wireless signal receiver in a wireless device. Received data is communicated from the receiver to a play-out buffer in communication with a media play-out device. The level of data in the play-out buffer increases when received data is written to the buffer, and the level of data decreases when data is read from the buffer. If the level of data is above a first watermark level, the receiver is transitioned to a sleep mode while data is read from the buffer. When the level of data in the buffer falls below a second watermark level, the receiver is transitioned back to an active mode to receive data. The device communicates status messages (whether the receiver is asleep or active) to the transmitting device so that the transmitting device stops transmitting data when the receiver is in sleep mode, and transmits data when the receiver is in the active mode.

Abstract: In accordance with unscheduled automatic power save delivery (U-APSD) mechanisms, an access point typically creates an unscheduled service period irrespective of availability of downlink data packets for a WLAN device. This can result in a large overhead that can limit the performance and throughput of the WLAN device. Functionality can be implemented on the access point and/or on the WLAN device so that the access point suppresses creating the service period (and transmitting an indication of an end of the service period) when there are no downlink data packets for the WLAN device. In some implementations, configuring the access point to defer creating the service period until it is determined that the WLAN device has transmitted all scheduled uplink data packets, or until the access point has available downlink data, can facilitate conservation of radio resources, and reduce power consumption.

Abstract: A method and an apparatus reduce power used when a traffic load is low in a base station of a wireless communication system. The base station monitors a traffic load. When the traffic load is lower than a predetermined threshold and a Multiple Input Multiple Output (MIMO) mode is used to communicate with a mobile station, the MIMO mode is converted to a Single Input Multiple Output (SIMO) mode.

According to another embodiment, when the traffic load is lower than a predetermined threshold, the base station limits the number of Resource Blocks (RBs) that may be allocated to a coverage area of the base station. A Power Amplifier (PA) bias related to a transmission output of the base station is reduced based on the limited number of RBs, thereby saving power consumption of the base station.

Abstract: A method and an apparatus for determining transmission power are disclosed. A gain factor of an E-DPDCH in a compressed mode is determined according to the number of E-DPDCHs used for initial transmission of data; and the transmission power of the E-DPDCH is determined according to the gain factor of the E-DPDCH in compressed mode. As the gain factor of E-DPDCH in compressed mode is determined according to the number of the E-DPDCHs for initial transmission of data, the gain factor of the E-DPDCH in compressed mode can be determined accurately, and thus the transmit power of the E-DPDCH can be determined accurately according to the gain factor of the E-DPDCH. Therefore, the waste of transmit power of the E-DPDCH is reduced, and thus the system capacity is improved.

Abstract: Optimizing a power level for a transmission so that the transmission is receivable at or near a destination, but no farther, is useful for reduced-power transmissions.

An obstruction database may be consulted to determine whether transmissions will degrade due to objects in between the transmitter and receiver, permitting power level, frequency, bandwidth or transmit/receive location to be adjusted accordingly.

Abstract: A system and method are disclosed for controlling transmit power amplification in a wireless transmitting device. A processor receives data to determine whether a communication channel from a transmitting device to a receiving device is strong enough to support a target data transmit rate of the devices with a power amplifier either on or off. The processor controls a switching device between a data transmitter circuit and the transmitter's antenna based on the quality of the communication channel. In a first state, the switching device connects the data transmitter circuit to the power amplifier to increase the strength of the signal communicated to the antenna. In a second state, the switching device bypasses the power amplifier. The power amplifier is turned off when the switch is in the second state, thereby decreasing the power consumed by the transmitting device as it transmits data at the target data transmit rate.
