Abstract:
In general, the subject matter described in this specification can be embodied in methods, systems, and program products for generating a schedule to transmit data on a network. The method includes accessing information that identifies a quantity of data that a particular client device has designated for transmission. The method includes determining, using the information that identifies the quantity of data for each of multiple client devices, a first schedule that identifies a subset of packet time segments, from a frame that includes packet time segments, during which a first client device is permitted to transmit data to the computing system. The first client device is one of the multiple client devices. The information includes transmitting the first schedule. The schedule includes receiving a transmission of data from the first client device during the identified subset of packet time segments in accordance with the schedule.
Abstract:
In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for adapting data rate. The method includes receiving a data transmission at a data rate, identifying a first quantity of packets that were not adequately received, and using the first quantity to increase a packet loss level. A second quantity of improper bits in those packets that were adequately received at the data rate are identified, and the second quantity is used to increase a bit error level. As a result of having determined that the first value does not satisfy a first criterion for reducing the rate of the data transmission and that the second value does satisfy a second criterion for increasing the rate of the data transmission, an instruction is sent for causing the sending device to increase the rate of the data transmission.
Abstract:
A technique includes communicating with a base station via a transmitter and a receiver of a first client device based on a static schedule. The static schedule indicates an uplink time and a downlink time allocated to the first client device and associated with each of multiple frames of the base station. Communication time between the base station and multiple client devices linked to the base station including the first client device is divided into multiple frames. A mode request signal is transmitted or received and performs one of: (i) requesting operation in a sleep mode for a selected number S of the frames, and (ii) indicating operation in a standby mode. An initiate signal is transmitted from the first client device to the base station via the transmitter and indicates when to begin operating in the one of the sleep mode and the standby mode.
Abstract:
Certain implementations of the disclosed technology may include systems and methods for computing device communications. According to an example implementation of the disclosed technology, a method is provided that can include determining a status and capability of at least one selected computing device, and sending a generated message to the at least one selected computing device. The at least one selected computing device is configured to retrieve content from a source identified by a uniform resource identifier in the message, and the at least one selected computing device is further configured to present the retrieved content.

Abstract:
A technique includes (i) receiving a first pilot signal from a base station via a receiver of a client device, or (ii) transmitting a second pilot signal from the client device to the base station via a transmitter of the client device. First time differences and signal quality values for N samples of N respective packets in the first pilot signal are determined. Second time differences and signal quality values are received via the receiver. The second time differences and signal quality values are generated for M samples of M respective packets in the second pilot signal. An offset value is determined based on (i) the first time differences and signal quality values, or (ii) the second time differences and signal quality values. Activation or deactivation times of the receiver or the transmitter or transmission times of the transmitter are adjusted based on the offset value.
Abstract:
In general, the subject matter described in this specification can be embodied in methods, systems, and program products for adaptive data unit transmission. A sliding window is filled with data units and designates a sliding window start position and a sliding window end position. A value for each of the data units in the sliding window is stored, the value representing a maximum number of times that each data unit is to be transmitted. The stored value is different among at least two of the data units. Data units are selected from the sliding window to be assembled into a packet. An assembled packet is transmitted to a receiving computerized device. A determination that the data unit positioned at the sliding window start position has been transmitted a maximum number of time is performed, and in response a different data unit is positioned at the sliding window start position.

Abstract:
In general, the subject matter described in this specification can be embodied in methods, systems, and program products for adapting data rate in a communication system. A receiving device receives a data transmission at an initial data rate. The device determines, based on an error rate of the data transmission at the initial data rate, that a first criterion is satisfied for requesting an increase in the data transmission. The device requests that a transmitting device increase the data transmission from the initial data rate to the first subsequent data rate. The device determines, based on an error rate of the data transmission at the first subsequent data rate, whether a second criterion is satisfied for maintaining the first subsequent data rate. The device maintains, if the second criterion is determined to be satisfied, a state of the device for receiving the data transmission at the first subsequent data rate.
