  • Reducing power consumption in devices has various benefits, including reducing the amount of (and thus money spent on) energy used by the UEs and, for UEs that include a battery, extending the amount of time a UE can run from a charged battery.
  • UEs are oftentimes able to operate in a low power mode in certain situations in order to reduce power consumption, such as when the UE is not being used for an energy-intensive activity such as a voice call or video call, audio/video playback, gaming, and so forth.
  • An additional goal for many UEs is to provide high performance, performing tasks quickly when requested by a user. Unfortunately, while such low power modes reduce the amount of energy used by the UE, these low power modes typically reduce the performance of the UE.

  • the low power wake up radio When waking up the main radio, the low power wake up radio includes the information regarding the main radio that was received as part of the LP-WUS.

Accordingly, power can be conserved due to the main radio being in a low power mode, but the main radio can also begin to operate more quickly when coming out of the low power mode because the main radio receives the state or settings information from the low power wake up radio.

Abstract

Divers aspects de la présente divulgation concernent un dispositif qui comprend une radio principale et une radio de réveil faible puissance (LP-WUR). La radio principale peut être mise dans un mode faible puissance. Le LP-WUR écoute un signal de réveil faible puissance (LP-WUS) provenant d'un autre dispositif (par exemple, une entité de réseau), et en réponse à la réception du LP-WUS, le LP-WUR réveille la radio principale. Le LP-WUS comprend des informations concernant la radio principale, que le LP-WUR fournit à la radio principale lors du réveil de la radio principale au sujet de la radio principale. Ces informations peuvent comprendre des informations relatives à un état de transition de la radio principale, une indication de l'un de multiples cycles de réception discontinue à appliquer à la radio principale et/ou une indication de comportement de dormance ou de non-dormance pour une ou plusieurs cellules secondaires au niveau de la radio principale.
