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 supporting enhanced SIM replacement procedure is proposed. A UE detects that a first identification module running a first application is inserted. The first identification module belongs to a PLMN, and an enhanced service is provided by an operator of the PLMN via a second application. The UE sends a notification to the operator for obtaining a second identification module. The UE detects that the second identification module running the second application is inserted. The UE sends a second notification to the operator for activating the second identification module such that the UE is able to use the enhanced service provided by the operator. The device-assisted solution for SIM replacement complies with existing security/authentication model, has no standard charge, and complies with existing SIM replacement model and offers a simpler and more automatic procedure.

摘要： A method of measurement gap reporting and configuration is provided. In a mobile network, a UE receives a capability enquiry message from a serving base station. The UE comprises one or more radio frequency modules that support a list of frequency bands and a list of carrier aggregation (CA) band combinations. In response to the enquiry, the UE transmits capability information containing measurement parameters to the base station. In one embodiment, the measurement parameters comprise need-for-gap parameters for each frequency band and each CA band combinations associated with a list of to-be-measured frequency bands of target cells. Based on the reported measurement parameters, the eNB transmits a measurement configuration message to the UE. Finally, the UE transmits a measurement gap application message back to the base station. The measurement gap application message indicates whether the UE applies MG for each configured component carrier.

摘要： A method of implicit signaling to support In-Device coexistence interference avoidance is provided. A UE sends an IDC interference indication to an eNB. The indication indicates that a serving frequency becomes unusable due to a coexistence interference problem. The indication does not explicitly indicate a frequency index or a frequency location of the unusable serving frequency. The eNB determines the serving frequency as unusable in an implicit manner. The eNB also determines an implied unusable frequency region based on the received IDC indication. The implied unusable frequency region is between the serving frequency and the ISM band. In one advantageous aspect, the eNB configures a condition for the UE, such that the UE is refrained from sending IDC interference indications unless the condition is satisfied.

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： In a carrier assignment procedure, a mobile station and its serving base station exchange and negotiate carrier deployment and multi-carrier capability information, and make a well- informed carrier assignment decision based on the negotiation result. The carrier assignment procedure ensures that the assigned secondary carriers are not only supported by both the serving BS and the MS, but are also desirable under additional requirements and considerations. Furthermore, the carrier assignment decision may be updated based on additional considerations such as channel quality measurement and network load condition over the assigned carriers. Such updated assignment decision may be made by the base station in unsolicited manner, or based on a carrier re-assignment request from the mobile station.

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 Femto Base Station (FBS) includes a communication functionality and a reliability functionality. A control entity within the reliability functionality detects an FBS reliability compromising event (for example, an unscheduled loss of external power to the FBS). As a result of detecting the FBS reliability compromising event, the control entity sends a message (an "FBS Reliability Compromising Event Compensation Message" or "FBSRCECM") to the communication functionality. The FBSRCECM initiates an action that compensates for the FBS reliability compromising event. In many examples, the action is the initiating of a handover from the FBS to another base station. The reliability functionality typically includes a rechargeable battery that powers the FBS for a time until the handover is completed gracefully. By performing a graceful handover, cellular network reliability is improved as compared to situations in which a conventional FBS simply stops working and connections handled by the conventional FBS are broken.

摘要： A method of data transmission over guard sub-carriers is provided in a multi-carrier OFDM system. Adjacent radio frequency (RF) carriers are used to carry radio signals transmitted through adjacent frequency channels. A plurality of guard sub-carriers between adjacent frequency channels are aligned and identified for data transmission in a pre-defined physical resource unit. The identified guard sub-carriers do not overlap with normal data sub-carriers of the radio signals transmitted through the adjacent frequency channels. At least one of the identified guard sub-carriers is reserved as NULL sub-carrier. A flexible multi-carrier transceiver architecture is also provided in a multi-carrier OFDM system. Different multi-carrier and/or MIMO/SISO data transmission schemes are implemented by adaptively reconfigure same hardware modules including common MAC layer module, physical layer entities, and RF entities. Furthermore, the flexible multi-carrier transceiver architecture can be used to support data transmission over guard sub-carriers.
