摘要： A wireless device having a central control entity that coordinates multiple radio transceivers co-located within the same device platform to mitigate coexistence interference. The wireless device comprises an LTE transceiver, a WiFi transceiver, a BT transceiver, or a GNSS receiver. In one embodiment, the central control entity receives radio signal information from the transceivers and determines control information. The control information is used to trigger FDM solution such that the transceivers operate in designated frequency channels to mitigate co-existence interference. In another embodiment, the central control entity receives traffic and scheduling information from the transceivers and determines control information. The control information is used to trigger TDM solution such that the transceivers are scheduled for transmitting or receiving radio signals over specific time duration to mitigate co-existence interference. In yet another embodiment, power control solution is used to mitigate coexistence interference.

摘要： An apparatus and method for transmitting outgoing data uses data descriptors for multiple sets of contiguous data blocks stored in buffers. When new sets of contiguous data blocks are created due to acknowledgement signals for particular data blocks of the multiple sets of contiguous data blocks, new data descriptors are generated for some of the new sets of contiguous data blocks. These new data descriptors are placed in spaces in the buffers where the particular data blocks were originally stored.

摘要： An open-loop fast link adaptation scheme is proposed in an OFDM system. An access point first transmits a downlink packet comprising an open-loop link metric to a wireless station. The open-loop link metric contains a transmit power of the downlink packet plus a receiver sensitivity of the access point. The wireless station measures a received signal strength indication (RSSI) value of the downlink packet. The wireless station then applies open-loop link adaptation and determines a modulation and coding scheme (MCS) based on the open-loop link metric and the RSSI value. The open-loop link adaptation scheme is especially suitable for smart meter/sensor networks as it reduces overhead and increases link capacity.

摘要： Wireless local area networks must work in less than ideal environments, including environments having externally and internally generated interfering RF signals. Interfering signals can cause significant problems with signal detecting, amplifier gain adjustment, and signal decoding. Various parameters of the WLAN receiver can be adjusted to mitigate the effects of interference. By selectively adjusting sets of these parameters, receiver sensitivity and interference immunity can be advantageously balanced. In one embodiment, adjustments to these parameter sets can be made in response to different sources of interference.

摘要： An accurate total error rate performance can be measured using a computed error vector magnitude (EVM) per stream. Using this EVM, the receiver or the transmitter can advantageously generate an optimized modulation and coding scheme (MCS) that corresponds to a specific number of streams, modulation and coding rate for the transmitter. For example, the receiver can compute an SNR from the EVM and then use an SNR vs. MCS table to determine the optimized MCS. In contrast, the transmitter can receive an EVM-to-RSSI mapping and an EVM-to-MCS mapping from the receiver. These mappings and an EVM can facilitate selecting the optimized MCS.
