    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 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.

    摘要: A method of simultaneously providing channel quality feedback information in all valid sub-channels is provided to facilitate and improve the performance of dynamic transmission bandwidth adjustment and fast link adaptation. A receiving device receives a sounding signal over a wide channel in a wireless system. The sounding signal is transmitted from a transmitting device over multiple sub-channels of the wide channel. The receiving device estimates channel quality information based on the sounding signal for each sub-channel. The channel quality information includes estimated average SNR and recommended MCS and other channel quality metrics. The receiving device transmits a feedback message to the transmitting device. The feedback message contains the estimated channel quality information for all valid sub-channels within the transmission bandwidth. The transmitting device performs dynamic transmission bandwidth selection and fast link adaptation based on the channel quality information for all valid sub-channels.

    摘要: A method of supporting incompatible channelization in a wireless communications system is provided. A coordinating device determines a first set of physical parameters of a first wireless channel. The first set of physical parameters includes a channel bandwidth, a central frequency, a transmit power limit, and a modulation and coding scheme. The coordinating device establishes communication with a first set of communications devices over the first wireless channel. The coordinating device then broadcasts a channel-adjustment message and determines a protection period. The channel-adjustment message comprises a set of instructions on how to adjust to a second set of physical parameters of a second wireless channel. A second set of communications devices adjust physical parameters based on the channel-adjustment message. Finally, the coordinating device communicates with the second set of communications devices over the second wireless channel during the protection period.

    摘要: A scheduling-based down-link MU-MIMO mechanism is proposed in a wireless communication system. An access point transmits a first scheduling message to a plurality of stations. The first scheduling message reserves a first transmission burst for channel sounding. The AP then transmits a sounding signal and in response receives channel state information (CSI) from the plurality of stations. Based on the CSI, the AP performs MU-MIMO encoding and applies transmit beamforming (precoding). The AP transmits a second scheduling message that reserves a second transmission burst for MU-MIMO transmission. The AP then transmits downlink data streams to multiple stations simultaneously. Finally, the AP receives uplink acknowledgements from the stations. In one embodiment, the scheduling-based MU-MIMO is implemented using PSMP scheduling technique. PSMP-based downlink MU-MIMO allows both 802.11n and 802.11ac stations to process multiple spatial streams with reduced complexity, enhanced performance, and significant power saving.

    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.
