Abstract

Técnicas para manejar las diferencias en la temporización en la transmisión de enlace ascendente entre las portadoras agregadas o los grupos de portadoras. En un grupo de formas de realización de estas técnicas, se provee un mecanismo basado en terminal móvil. En un método ejemplificativo de acuerdo con estas formas de realización, una terminal móvil determina (830) que una diferencia en la temporización en la transmisión de enlace ascendente entre una primera portadora o grupo y una segunda portadora o grupo ya es o será mayor que un umbral de diferencia de temporización y, en respuesta a dicha determinación, gestiona (840) una acción con respecto al menos a una portadora de enlace ascendente como para evitar que el umbral de diferencia de temporización sea excedido por las diferencias de temporización en la transmisión de enlace ascendente en una o más transmisiones de enlace ascendente subsiguientes.Techniques for handling differences in timing in uplink transmission between aggregate carriers or carrier groups. In a group of embodiments of these techniques, a mechanism based on mobile terminal is provided. In an exemplary method according to these embodiments, a mobile terminal determines (830) that a difference in timing in uplink transmission between a first carrier or group and a second carrier or group is already or will be greater than a timing difference threshold and, in response to said determination, manages (840) an action with respect to at least one uplink carrier as to prevent the timing difference threshold from being exceeded by timing differences in the transmission of uplink on one or more subsequent uplink transmissions.
