摘要： A wireless communication device is provided with a first radio module and a second radio module inside. The first radio module performs wireless transceiving according to a plurality of first traffic patterns which each indicates allocations of a plurality of first slots for a plurality of forthcoming transmitting or receiving operations, respectively. The second radio module determines an indicator indicating at least one of a plurality of second traffic patterns which each indicates allocations of a plurality of second slots for a plurality of forthcoming transmitting or receiving operations, respectively. Particularly, one or more allocations of the second slots are selectively determined according to the first traffic patterns. Also, the second radio module transmits the indicator to a peer communication device, so that the peer communication device performs transmitting or receiving operations according to the indicator.

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： A method of scheduling transmitting and receiving communication slots for co-located radio devices is provided. A Bluetooth (BT) device first synchronizes its communication time slots with a co-located radio module, and then obtains the traffic pattern of the co-located radio module. Based on the traffic pattern, the BT device selectively skips one or more TX or RX time slots to avoid data transmission or reception in certain time slots and thereby reducing interference with the co-located radio module. In addition, the BT device generates a co-located coexistence (CLC) bitmap and transmits the CLC bitmap to its peer BT device such that the peer BT device can also skip data transmission or reception in certain time slots affected by the co-located radio module. The skipped time slots are disabled for TX or RX operation to prevent interference and to achieve more energy saving.

摘要： A communications apparatus is provided. A first radio module provides a first wireless communications service and communicates with a first communications device in compliance with a first protocol. A second radio module provides a second wireless communications service and communicates with a second communications device in compliance with a second protocol. A Co-Located Coexistence radio manager detects activities of the first radio modules, obtains a first traffic pattern describing downlink and/or uplink traffic allocations of the first radio module from the first radio module, and generates a second traffic pattern of the second radio module according to the first traffic pattern to coordinate operations of the first and second radio modules. The second traffic pattern describes recommended downlink and/or uplink traffic allocations to a plurality of subframes for the second radio module, and each sub-frame defined by the second protocol includes Orthogonal Frequency Division Multiplexing symbols.
