Apparatus and method for coexistence between Wi-Fi communication and Bluetooth communication
Provided herein are apparatus and methods for coexistence between Wi-Fi communication and Bluetooth communication. An apparatus for a UE includes: a Wi-Fi module to perform Wi-Fi communication; a Bluetooth module to perform Bluetooth communication; and interface circuitry coupled with both of the Wi-Fi module and the Bluetooth module; wherein the Wi-Fi module is to: obtain event schedule information from the Bluetooth module via the interface circuitry, wherein the event schedule information is to indicate information about a schedule of the Bluetooth communication; and puncture, based on the event schedule information, a secondary channel for the Wi-Fi communication to reserve a sub-channel for the Bluetooth communication. Other embodiments may also be disclosed and claimed.
1. An apparatus for a User Equipment (UE), the apparatus comprising:
a wireless fidelity (Wi-Fi) module to perform Wi-Fi communication;
a Bluetooth module to perform Bluetooth communication; and
interface circuitry coupled with both of the Wi-Fi module and the Bluetooth module;
wherein the Wi-Fi module is to:
obtain event schedule information from the Bluetooth module ahead of a time period than occurrence of the Bluetooth communication via the interface circuitry, wherein the event schedule information is to indicate information about a schedule of the Bluetooth communication; and
puncture, based on the event schedule information, a secondary channel for the Wi-Fi communication to reserve a sub-channel for the Bluetooth communication,
wherein the event schedule information is to indicate a bandwidth of the sub-channel, start time of the Bluetooth communication, and a duration of the Bluetooth communication, and
wherein the time period ahead of the occurrence of the Bluetooth communication is based on interacting time required between the Wi-Fi module and a Wi-Fi Access Point (AP) in updating puncturing schedule and time required by the Bluetooth module for updating hopping sequence.
2. The apparatus of claim 1 , wherein the Wi-Fi module is to:
puncture the secondary channel for the Wi-Fi communication to reserve the sub-channel with the bandwidth starting from the start time for the duration.
3. The apparatus of claim 1 , wherein the secondary channel for the Wi-Fi communication is 20 MHz in bandwidth.
4. The apparatus of claim 1 , wherein the schedule of the Bluetooth communication is periodic or bursty.
5. The apparatus of claim 1 , wherein the Bluetooth communication includes a Bluetooth Low Energy (BLE) advertising message or a Basic Rate/Enhanced Data Rate (BR/EDR) inquiry/page packet.
6. The apparatus of claim 1 , wherein the Wi-Fi module is further to:
puncture the secondary channel for the Wi-Fi communication to further reserve a guard channel on either side of the sub-channel.
7. The apparatus of claim 6 , wherein the guard channel is 1 MHz in bandwidth.
8. The apparatus of claim 1 , wherein the bandwidth of the sub-channel is 2 MHz.
9. An apparatus for a User Equipment (UE), the apparatus comprising:
a wireless fidelity (Wi-Fi) module to perform Wi-Fi communication;
a Bluetooth module to perform Bluetooth communication; and
interface circuitry coupled with both of the Wi-Fi module and the Bluetooth module;
wherein the Bluetooth module is to:
generate event schedule information for transmission, ahead of a time period than occurrence of the Bluetooth communication, to the Wi-Fi module via the interface circuitry, wherein the event schedule information is to indicate information about a schedule of the Bluetooth communication; and
cause to perform the Bluetooth communication via a sub-channel after a time period since the transmission of the event schedule information to the Wi-Fi module, wherein the sub-channel is punctured from a secondary channel for the Wi-Fi communication by the Wi-Fi module based on the event schedule information,
wherein the event schedule information is to indicate a bandwidth of the sub-channel, start time of the Bluetooth communication, and a duration of the Bluetooth communication, and
wherein the time period ahead of the occurrence of the Bluetooth communication is based on interacting time required between the Wi-Fi module and a Wi-Fi Access Point (AP) in updating puncturing schedule and time required by the Bluetooth module for updating hopping sequence.
10. The apparatus of claim 9 , wherein the secondary channel for the Wi-Fi communication is 20 MHz in bandwidth.
11. The apparatus of claim 9 , wherein the schedule of the Bluetooth communication is periodic or bursty.
12. The apparatus of claim 9 , wherein the Bluetooth communication includes a Bluetooth Low Energy (BLE) advertising message or a Basic Rate/Enhanced Data Rate (BR/EDR) inquiry/page packet.
13. The apparatus of claim 9 , wherein the bandwidth of the sub-channel is 2 MHz.
