Abstract
Methods, systems, and devices are described for efficient use of transmit opportunities (TXOPs) through adjustment of contention window backoff time values to compensate for one or more TXOPs that may exceed a TXOP limit. A contention window value may be increased, for example, to provide other devices in the network with a fair opportunity for network access based at least in part on one or more TXOPs that exceed the TXOP limit. Allowing one or more transmissions to exceed a TXOP limit may provide enhanced efficiency as compared to having multiple transmissions.
Claims30
A method for wireless communications, comprising:
- determining a utilization of a transmit opportunity (TXOP) for a transmission of data from a wireless communication device;
- determining a difference between the utilization of the TXOP and a TXOP limit;
- aggregating the difference with an accumulated difference between at least one other TXOP and a TXOP limit for the at least one other TXOP;
- determining a relative excess between the accumulated difference and the TXOP limit;
- and
- adjusting a contention window value for a subsequent transmission from the wireless communication device based at least in part on the relative excess.
A communications device for wireless communications, comprising:
- a memory that stores instructions;
- and
- a processor coupled with the memory, wherein the processor and the memory are configured to:
- determine a utilization of a transmit opportunity (TXOP) for a transmission of data from a wireless communication device and determine a difference between the utilization of the TXOP and a TXOP limit;
- aggregate the difference with an accumulated difference between at least one other TXOP and a TXOP limit for the at least one other TXOP;
- determine a relative excess between the accumulated difference and the TXOP limit;
- and
- adjust a contention window value for a subsequent transmission from the wireless communication device based at least in part on the relative excess.
A communications device for wireless communications, comprising:
- means for determining a utilization of a transmit opportunity (TXOP) for a transmission of data from a wireless communication device;
- means for determining a difference between the utilization of the TXOP and a TXOP limit;
- means for aggregating the difference with an accumulated difference between at least one other TXOP and a TXOP limit for the at least one other TXOP;
- means for determining a relative excess between the accumulated difference and the TXOP limit;
- and
- means for adjusting a contention window value for a subsequent transmission from the wireless communication device based at least in part on the relative excess.
A non-transitory computer-readable medium comprising computer-readable code that, when executed, causes a device to:
- determine a utilization of a transmit opportunity (TXOP) for a transmission of data from a wireless communication device;
- determine a difference between the utilization of the TXOP and a TXOP limit;
- aggregate the difference with an accumulated difference between at least one other TXOP and a TXOP limit for the at least one other TXOP;
- determine a relative excess between the accumulated difference and the TXOP limit;
- and
- adjust a contention window value for a subsequent transmission from the wireless communication device based at least in part on the relative excess.
