摘要:
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.
