Abstract
A method for controlling multiple-input and multiple-output operation in a communication device includes communicating data using multiple-input and multiple-output operation, determining a set of parameters that indicate quality of service associated with communicating the data to another device, and comparing the set of parameters to a set of thresholds. When one or more parameters in the set of parameters exceed one or more thresholds in the set of thresholds, the multiple-input and multiple-output operation is disabled.
Claims17
A method for controlling multiple-input and multiple-output operation in a communication device, the method comprising:
- communicating data from the communication device to a second device using multiple-input and multiple-output operation, using both a first data rate and a second data rate at the same time, wherein the first data rate supports one of 802.11 HT40 or 802.11 HT20, and the second data rate supports 802.11 HT80;
- determining a set of parameters that indicate quality of service associated with communicating the data to the second device;
- comparing the set of parameters to a set of thresholds;
- and
- when one or more parameters in the set of parameters exceed one or more thresholds in the set of thresholds:
- disabling communication via the first data rate;
- and
- communicating the data using the multiple-input and multiple-output operation, using the second data rate;
- and
- when none of the parameters in the set of parameters exceeds the one or more thresholds in the set of thresholds:
- determining a battery level of the communication device;
- determining whether the battery level is below a first battery level threshold corresponding to the first data rate;
- determining whether the battery level is below a second battery level threshold corresponding to the second data rate;
- disabling communication via the first data rate when the battery level is below the first battery level threshold;
- and
- disabling communication via the second data rate when the battery level is below the second battery level threshold.
A communication device configured to control multiple-input and multiple-output operation for communicating data, the communication device comprising:
- a transceiver component configured to communicate data to a second device using multiple-input and multiple-output operation, using both a first data rate and a second data rate at the same time, wherein the first data rate supports one of 802.11 HT40 or 802.11 HT20, and the second data rate supports 802.11 HT80;
- a set of processors coupled to the transceiver component and configured to:
- determine a set of parameters that indicate quality of service associated with communicating the data to the second device;
- compare the set of parameters to a set of thresholds;
- and
- when one or more parameters in the set of parameters exceed one or more thresholds in the set of thresholds:
- initiate disabling communication via the first data rate;
- and
- continue communicating the data using the multiple-input and multiple-output operation, using the second data rate;
- and
- when none of the parameters in the set of parameters exceeds the one or more thresholds in the set of thresholds:
- determine a battery level of the communication device;
- determine whether the battery level is below a first battery level threshold corresponding to the first data rate;
- determine whether the battery level is below a second battery level threshold corresponding to the second data rate;
- initiate disabling communication via the first data rate when the battery level is below the first battery level threshold;
- and
- initiate disabling communication via the second data rate when the battery level is below the second battery level threshold.
