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 to trigger in-device coexistence (IDC) interference mitigation is provided. A wireless device comprises a first radio module and a co-located second radio module. The first radio module measures a received radio signal based on a plurality of sampling instances. A control entity obtains Tx/Rx activity of the second radio module and informs Tx/Rx timing information to the first radio module. The first radio module determines a measurement result based on the obtained timing information. The first radio module triggers an IDC interference mitigation mechanism if the measurement result satisfies a configurable condition. In one embodiment, the first radio module reports IDC interference information and traffic pattern information of the second radio module to a base station for network-assisted coexistence interference mitigation. The IDC triggering mechanism prevents unnecessary and arbitrary IDC request from the device and thus improves network efficiency.

摘要： A coexistence interference mitigation method is provided. In a wireless network, a wireless device is equipped with multiple radios in the same device platform. The wireless device also has a control entity that communicates with the multiple co-located radio modules. A first radio module receives a notification from the control entity. The notification informs a critical signaling status of a second radio module co-located with the first radio module. Upon receiving the notification, the first radio module stops uplink transmission due to coexistence interference and transmits a coexistence indicator to its serving eNB. After a certain period, the first radio module receives a second notification that informs a completion status of the critical signaling of the second radio module. Upon receiving the second notification, the first radio module resumes uplink transmission and transmits a coexistence resume indicator to the eNB.

摘要： A method of power headroom reporting (PHR) is proposed. A UE is configured with a plurality of component carriers (CCs) and is served by one or more power amplifiers (PAs) in a wireless system with carrier aggregation. The UE determines transmit power limitation (TPL) information that comprises a set of TPL values, each TPL value corresponds to a UE-configured maximum transmit power for UE-level, PA-level, and CC-level. The TPL information is then reduced to non-redundant TPL values. Based on the non-redundant TPL values, the UE determines power headroom (PH) information that comprises a set of PH values. Each PH value equals to a TPL value subtracted by a UE-calculated transmit power. The UE reports the PH information to a base station via a fixed-length or variable-length MAC CE at each PHR reporting instance.
