Mitigating the Impact of Power Imbalances on Long-Range Data Rates in Wireless LANs

Abstract

A method for mitigating the impact of a power imbalance on a remote data rate in a wireless local area network (WLAN) includes transmitting a wireless local area network (WLAN) acknowledgement (ACK) packet at a first transmit power level to a remote device. The method further includes transmitting, to the remote device, a WLAN data packet at a second transmit power level that is lower than the first transmit power level of the WLAN ACK packet. Another method for mitigating the impact of a power imbalance on a remote data rate in a wireless local area network (WLAN) may include selecting a wireless local area network (WLAN) acknowledgement (ACK) packet transmit rate independent from a rate at which a WLAN data packet is received. This method further includes transmitting, to a remote device, a WLAN ACK packet at the selected WLAN ACK packet transmit rate.

Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and t...

AI Technical Summary

Problems solved by technology

Therefore, if the eNB uses RSRP reports to make handover decisions, a ping-pong effect of moving back and forth between the degraded channel and the desired channel may occur

[0011] Other unilateral actions on the part of the UE, such as simply stopping uplink communication, may cause power loop failure at the eNB without the cooperation of the eNB

Other problems present in conventional LTE include a general lack of ability on the part of the UE to suggest desired configurations as alternatives to configurations with coexistence issues

For at least these reasons, the uplink coexistence problem at the UE may remain unresolved for a longer period of time, degrading the performance and efficiency of other radio units of the UE
