==AGGRESSIVE EXTRA MICROSLEEP USING STALE CHANNEL ESTIMATE AND NOISE ESTIMATE TO DECODE CONTROL CHANNEL - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17654011 titled 'AGGRESSIVE EXTRA MICROSLEEP USING STALE CHANNEL ESTIMATE AND NOISE ESTIMATE TO DECODE CONTROL CHANNEL

==Simplified Explanation==

The patent application describes a method to reduce power consumption in user equipment (UE) by triggering a microsleep when a physical downlink control channel (PDCCH) does not include a downlink grant. However, the microsleep can only be triggered after decoding the PDCCH, which delays the sleep. To address this, the invention proposes an aggressive extra microsleep by reducing the PDCCH decode time. This is achieved by using a previous subframe's channel estimate and noise estimate for PDCCH demapping when certain conditions related to a PDCCH block error rate are met. This reduces the PDCCH decode time, allowing the UE to trigger the microsleep sooner and increase power savings.

* A user equipment (UE) triggers a microsleep when a physical downlink control channel (PDCCH) does not include a downlink grant.
* The microsleep can only be triggered after decoding the PDCCH, causing a delay in sleep.
* An aggressive extra microsleep is enabled by reducing the PDCCH decode time.
* The UE uses a stale channel estimate and noise estimate from a previous subframe for PDCCH demapping when certain conditions related to a PDCCH block error rate are satisfied.
* Removing channel estimation and noise estimation from the PDCCH demapping path reduces the PDCCH decode time.
* The UE can trigger the microsleep sooner, increasing the sleep ratio and power savings.

==Potential Applications==
* Mobile communication systems
* Wireless networks
* Power-saving techniques in user equipment

==Problems Solved==
* Reducing power consumption in user equipment
* Enabling quicker triggering of microsleep to increase power savings

==Benefits==
* Increased power savings in user equipment
* Reduced power consumption in mobile communication systems
* Improved efficiency in wireless networks


==Original Abstract Submitted==

To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.
