Abstract

Techniques for enhanced co-existence for co-located radios are described. A mobile computing device may comprise a first radio module operative to communicate wirelessly across a first link using a first set of communications channels, a second radio module operative to communicate wirelessly across a second link using a second set of communications channels, and a coordination module operative to receive information regarding operation of the first and second radio modules, and modify a communications parameter for the first or second radio module based on the received information. Other embodiments are disclosed and claimed.

Claims

1. A mobile computing device, comprising:

a first radio module to communicate wirelessly across a first link using a first set of communications channels;

a second radio module to communicate wirelessly across a second link using a second set of communications channels; and

a coordination module to receive information regarding operation of the first and second radio modules, and modify a communications parameter for the first or second radio module based on the received information.

2. The mobile computing device of claim 1, the communications parameter comprising a fragmentation parameter, an aggregation parameter, a packet retry parameter, a rate selection parameter, a window size parameter, a frequency parameter, a clock speed parameter, a power parameter, a delay parameter, or a received signal strength indicator (RSSI) level.

3. The mobile computing device of claim 1, comprising an antenna and a shared antenna structure, the shared antenna structure comprising a combiner and at least one switch arranged to allow the first radio module and the second radio module to share the antenna for simultaneous operations or mutually-exclusive operations.

4. The mobile computing device of claim 1, the coordination module to receive information regarding operation of the first and second radio modules, and send a control directive to increase or decrease a data rate for the first or second radio module based on the received information.

5. A mobile computing device, comprising:

a first radio module to communicate wirelessly across a first link using a first set of communications channels;

a second radio module to communicate wirelessly across a second link using a second set of communications channels; and

a coordination module to receive density information for a communications environment for the first or second radio module, and determine a control directive to modify a communications parameter for the first or second radio module based on the density information.

6. The mobile computing device of claim 5, the coordination module to utilize a probability density function associated with the density information to select and modify the communications parameter.

7. The mobile computing device of claim 5, the communications parameter comprising a fragmentation parameter, an aggregation parameter, a packet retry parameter, a rate selection parameter, a window size parameter, a frequency parameter, a clock speed parameter, a power parameter, a delay parameter, or a received signal strength indicator (RSSI) level.

8. The mobile computing device of claim 5, the coordination module to receive information regarding operation of the first and second radio modules, and send a control directive to increase or decrease a window size for a communications protocol used by the first or second radio module based on the received information.

9. A mobile computing device, comprising:
