Title (EN) TIME MASK TECHNIQUES FOR SHORTENED TRANSMISSION TIME INTERVALS
(FR) TECHNIQUES DE MASQUE TEMPOREL POUR DES INTERVALLES DE TEMPS DE TRANSMISSION RACCOURCIS
Abstract:
(EN) Methods, systems, and devices for wireless communication are described that support time mask techniques for shortened transmission time intervals (sTTIs) that may enhance low latency communications. Time masks may be identified and applied for transmissions that use sTTIs, in a manner that provides increased portions of sTTI durations having higher transmission power, and thus increase the likelihood of successful reception of such transmissions at a receiver. In some cases, a transmitter, such as a user equipment (UE), may identify one or more sTTIs for transmissions of a first wireless service (e.g., an ultrareliable low-latency communication (URLLC) service). An sTTI may be identified based on a duration of a TTI associated with the first wireless service being below a threshold duration (e.g., a TTI duration of less than 1ms may be identified as an sTTI).
(FR) L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil qui prennent en charge des techniques de masque temporel pour des intervalles de temps de transmission raccourcis (sTTIs) qui peuvent améliorer des communications à faible latence. Des masques temporels peuvent être identifiés et appliqués pour des transmissions qui utilisent des sTTIs, d'une manière à fournir des parties accrues de durées de sTTI ayant une puissance de transmission supérieure, et augmente ainsi la probabilité de réception réussie de telles transmissions au niveau d'un récepteur. Dans certains cas, un émetteur, tel qu'un équipement utilisateur (UE), peut identifier un ou plusieurs sTTIs pour des transmissions d'un premier service sans fil (par exemple, un service de communication à faible latence extrêmement fiable (URLLC)). Un sTTI peut être identifié sur la base d'une durée d'un TTI associé au premier service sans fil qui est inférieur à une durée seuil (par exemple, une durée de TTI inférieure à 1 ms peut être identifiée en tant que sTTI).
