Abstract

A base station may organize poll groups into groups having similar predicted durations of subsequent responses. In one embodiment predicted durations may be provided by the devices that are to be polled. In another embodiment the predicted durations may be based on past responses from the devices that are to be polled.

Claims

1. An apparatus, comprising

a first electronic device adapted to:

receive a data transmission from each of multiple second electronic devices, each of the data transmissions including a predicted duration of a subsequent transmission from the respective second electronic device;

organize at least some of multiple second electronic devices into a group having similar predicted durations for the subsequent data transmissions; and

transmit polls substantially simultaneously to the second electronic devices within the group.

2. The apparatus of claim 1, wherein the first electronic device is further adapted to receive the data transmissions from the second electronic devices within the group substantially simultaneously.

3. The apparatus of claim 1, wherein the first electronic device is further adapted to transmit acknowledgements to the wireless devices within the group substantially simultaneously.

4. The apparatus of claim 1, wherein the first electronic device is further adapted to transmit polls to other second electronic devices within another group substantially simultaneously.

5. The apparatus of claim 1, wherein the apparatus comprises:

a computing platform; and

at least four antennas coupled to the computing platform.

6. The apparatus of claim 5, wherein the apparatus further comprises at least four modulator/demodulators coupled between the computing platform and the at least four antennas.

7. A method, comprising:

receiving indicators from multiple electronic devices indicating predicted durations of subsequent transmissions from the electronic devices;

organizing, subsequent to said receiving, the multiple electronic devices into a first group having the indicators for the predicted durations of the subsequent transmissions within a particular range of a first value and into a second group having the indicators for the predicted durations of the subsequent transmissions within a particular range of a second value;

transmitting data polls to the electronic devices in the first group substantially simultaneously; and

transmitting data polls to the electronic devices in the second group substantially simultaneously, subsequent to said transmitting to the electronic devices in the first group.

8. The method of claim 7, further comprising determining the indicators for the predicted durations based on durations of previously received transmissions from the electronic devices, prior to said organizing.

9. A machine-readable medium that provides instructions, which when executed by a processing platform, cause said processing platform to perform operations comprising:

receiving indicators for predicted durations of subsequent transmissions from multiple electronic devices;

organizing the multiple electronic devices into a first group having the indicators for the predicted durations of the subsequent transmissions within a particular range of a first value and into a second group having the indicators for the predicted durations of the subsequent transmissions within a particular range of a second value;

transmitting data polls to the electronic devices in the first group substantially simultaneously; and

transmitting data polls to the electronic devices in the second group substantially simultaneously, subsequent to said transmitting to the electronic devices in the first group.

10. The medium of claim 9, wherein the operations further comprise determining the indicators for the predicted durations based on durations of previously received transmissions from the electronic devices, prior to said organizing.
