Abstract
A method for wireless communication is described. The method includes receiving a silent indication (SID) start message from a modem at a Bluetooth (BT) module when the modem detects a silent period in a voice call. The method also includes sending the SID start message from the BT module to a remote BT device. The method further includes disabling a BT transmitter during the silent period based on the SID start message received from the modem.
Claims22
A method for wireless communication, comprising:
- receiving, by a Bluetooth (BT) module in a wireless communication device, a silent indication (SID) start message and corresponding comfort noise over a modem interface from a separate modem in the wireless communication device, wherein the SID start message and the corresponding comfort noise are generated by the modem and the modem enters a discontinuous reception (DRX) mode in a voice call in response to detecting a silent period in the voice call, wherein the modem exits the DRX mode in the voice call and generates a SID end message in response to detecting that the silent period in the voice call has ended;
- sending the SID start message without the received corresponding comfort noise from the BT module to a remote BT device in a last Synchronous Connection Oriented (SCO) packet as a special non-speech packet indicating the SID start message;
- and
- disabling a BT transmitter during the silent period based on the SID start message received from the modem.

A wireless communication device comprising:
- a modem configured to detect a silent period in a voice call and to generate a silent indication (SID) start message and corresponding comfort noise and enter a discontinuous reception (DRX) mode in the voice call in response to detecting the silent period, wherein the modem exits the DRX mode in the voice call and generates a SID end message in response to detecting that the silent period in the voice call has ended;
- and
- a separate Bluetooth (BT) module configured to:
- receive the SID start message and corresponding comfort noise from the modem over a modem interface;
- send the SID start message without the received corresponding comfort noise to a remote BT device in a last Synchronous Connection Oriented (SCO) packet as a special non-speech packet indicating the SID start message;
- and
- disable a BT transmitter during the silent period based on the SID start message received from the modem.

An apparatus for wireless communication, comprising:
- means for receiving, at a Bluetooth (BT) module in the apparatus, a silent indication (SID) start message and corresponding comfort noise over a modem interface from a separate modem in the apparatus, wherein the modem comprises means for generating the SID start message and the corresponding comfort noise and means for entering a discontinuous reception (DRX) mode in a voice call in response to detecting a silent period in the voice call, wherein the modem comprises means for exiting the DRX mode in the voice call and means for generating a SID end message in response to detecting that the silent period in the voice call has ended;
- means for sending the SID start message without the received corresponding comfort noise from the BT module to a remote BT device in a last Synchronous Connection Oriented (SCO) packet as a special non-speech packet indicating the SID start message;
- and
- means for disabling a BT transmitter during the silent period based on the SID start message received from the modem.

A computer-program product for wireless communication, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:
- code for causing a Bluetooth (BT) module in a wireless communication device to receive a silent indication (SID) start message and corresponding comfort noise over a modem interface from a separate modem in the wireless communication device, wherein the SID start message and the corresponding comfort noise are generated by the modem and the modem enters a discontinuous reception (DRX) mode in a voice call in response to detecting a silent period in the voice call, wherein the modem exits the DRX mode in the voice call and generates a SID end message in response to detecting that the silent period in the voice call has ended;
- code for causing the BT module to send the SID start message without the received corresponding comfort noise to a remote BT device in a last Synchronous Connection Oriented (SCO) packet as a special non-speech packet indicating the SID start message;
- and
- code for causing the BT module to disable a BT transmitter during the silent period based on the SID start message received from the modem.
