Abstract: Techniques for compressing data in a wireless network are provided. Data may be in the form of data packets that have one or more headers and a payload. One or more compression initiation criteria are used to determine whether to compress all data or certain data. Different data may be associated with different classes of service. Compression initiation criteria for data that belongs to one class of service may be different than compression initiation criteria for data that belongs to another class of service. Compression initiation criteria for data may be different than one or more compression halting criteria that are used to determine whether to cease compressing data. One type of compression involves use of synchronized history buffers. A wireless receiver may communicate with a wireless transmitter that an error is detected and that the history buffers of the wireless transmitter should be flushed or cleared.

Abstract: According to techniques described herein LO leakage may be automatically minimized in a transmitter chain, even though the leakage may be varying in nature. In an embodiment a target signal for transmission is received. An offset for reducing the effects of the LO leakage is applied to the target signal. After the offset is applied, the target signal is converted to a transmission signal using the LO. A power associated with the transmission signal is determined. The offset is then adjusted based on the power associated with the transmission signal. In another embodiment, the offset signal is adjusted in a manner that minimizes the power associated with the transmission signal.

Abstract: A multi-radio device system includes a set of sending radio devices and a set of receiving radio devices. Among the sending radio devices is a load-balancing radio device that receives data packets from an originating network. The load-balancing radio device labels data packets with sequence numbers and distributes the labeled data packets among the sending radio devices based on the relative capacities and statuses of those sending radio devices. The sending radio devices transmit the labeled data packets to the receiving radio devices. The receiving radio devices send the labeled data packets to an aggregating radio device within the set of receiving radio devices. The aggregating radio device uses the sequence numbers to ensure that the data packets are forwarded to a destination network in the correct order, extracting original data packets from the labeled data packets before forwarding the original data packets on toward the destination network.

Abstract: A method and apparatus for decoding a baseband signal of a radio signal removes, from the baseband signal, low-frequency and long-term noise that increases the possibility of decoding errors. The removal of low-frequency and long-term noise is performed by accumulating differences between the actual signal levels of the baseband signal and the expected signal levels for the baseband signal and subtracting the accumulated difference from the baseband signal before decoding. In one scheme, the baseband signal contains a predetermined training sequence of signal levels, where the differences between the actual signal levels of the baseband signal and the expected signal levels for the predetermined training sequence are accumulated. At the end of the training sequence, the accumulated training sequence difference is used as the accumulated difference and subtracted from the baseband signal, thereby providing stable operation for decoding signal levels that follow the training sequence.

Abstract: When a signal-to-noise ratio affecting radio communication becomes sufficiently low, the data transmission rate is responsively decreased in compensation. The signal-to-noise ratio of the communication link is thereby increased. Data for multiple different services is transmitted in data packets between two radios. By allocating one part, or time slot, of the data packet's payload to one service, and allocating another part, or time slot, of the data packet's payload to another service, communications sessions for multiple services can be maintained concurrently. Services are prioritized relative to each other. In case the signal-to-noise ratio becomes too low, data packet portions that are related to lower-priority services can be omitted from some data packets before those data packets are transmitted. Data remaining in the packet can be sent at a reduced data transmission rate without causing the quality of service for the remaining packets to fall below the minimum required level.
