Abstract

Simultaneous operation of a short-ranged time division duplex (TDD) system with a mobile wireless broadband system may be implemented through scheduling and aligning both sets of communications. After determining a TDD frame configuration of the mobile wireless broadband system, a slot map is generated identifying slot-size selection information for each slot in the TDD frame configuration available for simultaneous operation. The slot-size selection information aligns the communication packet structure of the short-ranged TDD system and the uplink/downlink boundary of the TDD frame configuration. The communication device then transmits the slot map to a short-ranged TDD device for establishing the simultaneous operation.

Claims (43)

1. A method for simultaneous operation of a short-ranged time division duplex (TDD) mobile wireless system (MWS) with a mobile wireless broadband system, the method comprising:

determining, on a wireless communication device, a timing configuration of the mobile wireless broadband system;

generating, on a wireless communication device, based on the timing configuration, a time slot map identifying transmitting and receiving opportunities that enable simultaneous operation of the wireless systems within at least one time slot while mitigating interference between the wireless systems;

setting sniff anchor points based on guard bands of the timing configuration so short-ranged TDD MWS packets align with the guard bands; and

transmitting a message to a remote short-ranged TDD MWS device, the message setting an active communication period for the remote short-ranged TDD MWS device equal to a time period between successive guard bands in the timing configuration.

2. The method of claim 1 , in which the time slot map comprises packet length selection information aligning a communication packet structure of the short-ranged TDD system and an uplink/downlink boundary of the timing configuration between the wireless systems.

3. The method of claim 1 in which the determining, and the generating occur at a multi-system device, the multi-system device communicating on the mobile wireless broadband system and communicating with a remote short-ranged TDD MWS device on the short-ranged TDD MWS.

4. The method of claim 1 in which the determining comprises:

sensing an interference pattern indicative of the timing configuration, in which the sensing and the generating occur at a second short-ranged TDD MWS device in communication with a first short-ranged TDD MWS device.

5. The method of claim 1 :

in which the short-ranged TDD MWS comprises a BLUETOOTH® system; and in which the mobile wireless broadband system comprises one of:

a long term evolution (LTE) network; and

a WiMAX network.

6. An apparatus for simultaneous operation of a short-ranged time division duplex (TDD) mobile wireless system (MWS) with a mobile wireless broadband system, the apparatus comprising:

a memory; and

at least one processor coupled to the memory, wherein the at least one processor:

determines a timing configuration of the mobile wireless broadband system;

generates, based on the timing configuration, a time slot map identifying transmitting and receiving opportunities that enable simultaneous operation of the wireless systems within at least one time slot while mitigating interference between the wireless systems;

sets sniff anchor points based on guard bands of the timing configuration so short-ranged TDD MWS packets align with the guard bands; and

transmits a message to a remote short-ranged TDD MWS device, the message setting an active communication period for the remote short-ranged TDD MWS device equal to a time period between successive guard bands in the timing configuration.

7. The apparatus of claim 6 in which the at least one processor determines by sensing an interference pattern indicative of the timing configuration.

8. The apparatus of claim 6 in which the short-ranged TDD MWS comprises a BLUETOOTH® system; and

in which the mobile wireless broadband system comprises one of:

a long term evolution (LTE) network; and

a WiMAX network.

9. The apparatus of claim 6 , in which the time slot map comprises packet length selection information aligning a communication packet structure of the short-ranged TDD system and an uplink/downlink boundary of the timing configuration between the wireless systems.

10. A non-transitory computer readable medium tangibly storing code for simultaneously operating a short-ranged time division duplex (TDD) mobile wireless system (MWS) with a mobile wireless broadband system, the medium comprising:

code that is executed by a processor to determine a timing configuration of the mobile wireless broadband system;

code that is executed by a processor to generate, based on the timing configuration, a time slot map identifying transmitting and receiving opportunities that enable simultaneous operation of the wireless systems within at least one time slot while mitigating interference between the wireless systems;

code that is executed by a processor to set sniff anchor points based on guard bands of the timing configuration so short-ranged TDD MWS packets align with the guard bands;

code that is executed by a processor to transmit a message to a remote short-ranged TDD MWS device, the message setting an active communication period for the remote short-ranged TDD MWS device equal to a time period between successive guard bands in the timing configuration.

11. The medium of claim 10 , in which the time slot map comprises packet length selection information aligning a communication packet structure of the short-ranged TDD system and an uplink/downlink boundary of the timing configuration between the wireless systems.

12. The medium of claim 10 in which the determining code comprises code that is executed by a processor to sense an interference pattern indicative of the timing configuration.

13. The medium of claim 10 in which the short-ranged TDD MWS comprises a BLUETOOTH® system; and

in which the mobile wireless broadband system comprises one of:

a long term evolution (LTE) network; and

a WiMAX network.

14. A system for simultaneous operation of a short-ranged time division duplex (TDD) mobile wireless system (MWS) with a mobile wireless broadband system, the system comprising:

means for determining a timing configuration of the mobile wireless broadband system;

means for generating, based on the timing configuration, a time slot map identifying transmitting and receiving opportunities that enable simultaneous operation of the wireless systems within at least one time slot while mitigating interference between the wireless systems;

means for setting sniff anchor points based on guard bands of the timing configuration so short-ranged TDD MWS packets align with the guard bands; and

means for transmitting a message to a remote short-ranged TDD MWS device, the message setting an active communication period for the remote short-ranged TDD MWS device equal to a time period between successive guard bands in the timing configuration.

15. The system of claim 14 , in which the time slot map comprises packet length selection information aligning a communication packet structure of the short-ranged TDD system and an uplink/downlink boundary of the timing configuration between the wireless systems.
