1. A method comprising: receiving a notification from a control entity by a first radio module, wherein the control entity notifies a critical signaling status of a second radio module co-located with the first radio module; transmitting a coexistence indicator from the first radio module to a base station to prevent the base station from sending a false alarm and from triggering additional coexistence interference mitigation functions for the first radio module during a first period of time; and stopping uplink transmission with the base station for a second period of time by the first radio module and ignoring uplink transmission opportunity granted to the first radio module by the base station in response to the notification of the critical signaling status of the second radio module.
3. The method of claim 1, further comprising: receiving a second notification from the control entity, wherein the control entity notifies a completion status of the critical signaling of the second radio module; and resuming uplink transmission.
4. The method of claim 3, further comprising: transmitting a coexistence resume indicator to from the first radio module to the base station.
5. The method of claim 1, wherein the second radio module is a Bluetooth module, and wherein the critical signaling is part of an initial connection setup procedure.
6. The method of claim 1, wherein the second radio module is a Bluetooth module, and wherein the critical signaling is part of an adaptive frequency hopping (AFH) setup procedure.
7. The method of claim 1, wherein the second radio module adjusts a transmit power level based on a frequency distance from a frequency channel of the second radio module to a frequency channel of the first radio module.
8. The method of claim 1, wherein the second radio module adjusts a transmit power level based on a number of transmission failures.
9. A method comprising: receiving a coexistence indicator from a wireless device by a base station, wherein the coexistence indicator informs that the wireless device ignores uplink transmission opportunity granted by the base station and stops uplink transmission for a first period of time; configuring uplink measurement functions into abnormal status in response to the coexistence indicator, wherein the base station refrains from sending alarms and triggering additional coexistence interference mitigation functions for the wireless device during a second period of time; and receiving a coexistence resume indicator from the wireless device, wherein the base station configures the uplink measurement functions back to normal status.
10. The method of claim 9, wherein the uplink measurement functions include hybrid automatic repeat request (HARQ) function, and wherein the base station stops or resets an HARQ retransmission counter in abnormal status.
11. The method of claim 9, wherein the uplink measurement functions include uplink signal measurement function, and wherein the base station ignores uplink measurement results in abnormal status.
12. The method of claim 9, wherein the uplink measurement functions include minimization of driving test (MDT) function, and wherein the base station stops logging uplink measurement results for MDT in abnormal status.
14. A wireless device, comprising: a first radio module; a second radio module that is co-located with the first radio module; and a control entity that sends a notification to the first radio module, wherein the notification notifies the first radio module a critical signaling status of the second radio module, wherein the first radio module transmitting a coexistence indicator to a base station to prevent the base station from sending a false alarm and from triggering additional coexistence interference mitigation functions for the first radio module during a period of time, and wherein the first radio module ignores uplink transmission opportunity granted to the first radio module by the base station and stops an ongoing uplink transmission with the base station in response to the notification of the critical signaling status of the second radio module.
16. The device of claim 14, wherein the control entity sends a second notification to the first radio module notifying a completion status of the critical signaling of the second radio module, and wherein the first radio module resumes uplink transmission in response to the second notification.
17. The device of claim 16, wherein the first radio module transmits a coexistence resume indicator to the base station.
18. The device of claim 14, wherein the second radio module is a Bluetooth module, and wherein the critical signaling is part of an initial connection setup procedure.
19. The device of claim 14, wherein the second radio module is a Bluetooth module, and wherein the critical signaling is part of an adaptive frequency hopping (AFH) signaling procedure.
20. The device of claim 14, wherein the second radio module adjusts a transmit power level based on a frequency distance from a frequency channel of the second radio module to a frequency channel of the first radio module.
21. The device of claim 14, wherein the second radio module adjusts a transmit power level based on a number of transmission failures.

[0026] FIG. 4 is a simplified block diagram of a wireless device 41 having a central control entity to facilitate UE autonomous LTE denial. Wireless device 41 comprises memory 44, a processor 45 having a central control entity 46, a LTE/WiMAX transceiver 47, a WiFi transceiver 48, a Bluetooth transceiver 49, and bus 105. In the example of FIG. 8, central control entity 46 is a logical entity physically implemented within processor 45, which is also used for device application processing for device 41. Alternatively, central control entity 46 is a logical entity implemented within a processor that is physically located within the LTE/WiMAX transceiver, the WiFi transceiver, or the BT transceiver. Central control entity 46 is connected to various transceivers within device 41, and communicates with the various transceivers via bus 105. For example, BT transceiver 49 transmits BT signal information and/or BT traffic and scheduling information to central control entity 46 (e.g., depicted by a dotted line 101). Based on the received BT information, central control entity 46 determines control information and transmits the control information to LTE/WiMAX transceiver (e.g., depicted by a dotted line 102). In one embodiment, BT transceiver 49 performs initial connection setup with its peer BT device 43 (e.g., depicted by a dotted line 103). LTE/WiMAX transceiver 47 learns the BT activity through control entity 46 and performs autonomous LTE denial to protect the initial connection setup procedure. LTE/WiMAX transceiver 47 further communicates with its serving base station eNB42 to indicate its absence on Tx for a period of time (e.g., depicted by a dotted line 104) to prevent eNB false alarm.
