Abstract
According to an example, mobility-aware frame aggregation may include using mobility information related to a transmitter and/or a receiver associated with transmission of data over a wireless channel to determine an aggregation size for frame aggregation of the data to be transmitted over the wireless channel. The mobility information may be based on subcarriers and antennas related to the wireless channel.
Claims16
A method for mobility-aware frame aggregation, the method comprising:
- using channel state information (CSI) to determine, by a processor, a channel coherence time for a wireless channel between a mobile device and a wireless access point (AP), wherein the channel coherence time is a time duration during which the wireless channel changes due to movement of at least one of the mobile device and the wireless AP by less than a predetermined value;
- determining a bit-rate supported by the wireless channel;
- using a product of the channel coherence time and the bit rate supported by the wireless channel to determine an aggregation size for frame aggregation of packets to be transmitted over the wireless channel;
- using the determined aggregation size for frame aggregation of packets;
- and
- transmitting the packets over the wireless channel.
A mobility-aware frame aggregation apparatus comprising:
- a processor;
- and
- a memory storing machine readable instructions that when executed by the processor cause the processor to:
- determine channel state information (CSI) values for a time period;
- determine, using the CSI values for the time period, an average CSI correlation coefficient for a plurality of antennas;
- determine an aggregation size for frame aggregation of data to be transmitted over a wireless channel based on the average CSI correlation coefficient;
- use the determined aggregation size for frame aggregation of packets;
- and
- transmit the packets over the wireless channel.
A non-transitory computer readable medium having stored thereon machine readable instructions to provide mobility-aware frame aggregation, the machine readable instructions, when executed, cause a processor to:
- use mobility information related to at least one of a transmitter and a receiver associated with transmission of data over a wireless channel to determine a channel coherence time for the wireless channel, wherein the mobility information is based on an average correlation value determined based on a plurality of subcarriers and a plurality of antennas related to the wireless channel, wherein the channel coherence time is a time duration during which the wireless channel changes due to movement of at least one of a mobile device and a wireless access point (AP) by less than a user-specified value;
- use the channel coherence time to determine an aggregation size for frame aggregation of the data to be transmitted over the wireless channel;
- use the determined aggregation size for frame aggregation of packets;
- and
- transmit the packets over the wireless channel.
