Title
(EN) TDD RECONFIGURATION WITH CONSIDERATION OF DTX/DRX
(FR) RECONFIGURATION TDD PRENANT EN COMPTE LA DTX/DRX
Abstract
(EN) Methods, systems, and devices are described for discontinuous transmission and/or discontinuous reception in time division duplex (TDD) systems that may have data transmission formats dynamically reconfigured. An initial uplink-downlink (UL-DL) configuration for TDD communication between a base station and user equipment (UE) may be established. This initial UL-DL configuration may be reconfigured to a different UL-DL configuration for one or more UEs in communication with the base station. When a UE switches to discontinuous reception (DRX) mode, it may monitor control information from the base station during DRX on periods, the frequency of the DRX on periods based on a reference UL-DL configuration irrespective of any reconfiguration of UL-DL configuration for a particular UE. In some aspects, a UE that is operating in a UL-DL reconfiguration mode may, upon entering DRX mode, autonomously discontinue operating in the UL-DL reconfiguration mode.
(FR) L'invention a trait à des procédés, des systèmes et des dispositifs destinés à l'émission discontinue (DTX) et/ou à la réception discontinue (DRX) dans les systèmes duplex à répartition dans le temps (TDD) qui peuvent avoir des formats d'émission de données reconfigurés dynamiquement. Une configuration liaison montante-liaison descendante (UL-DL) initiale concernant la communication TDD entre une station de base et un équipement utilisateur (UE) peut être créée. Cette configuration UL-DL initiale peut être reconfigurée pour aboutir à une configuration UL-DL différente relative à un ou plusieurs UE en communication avec la station de base. Lorsqu'un UE passe en mode DRX, il peut attendre des informations de commande provenant de la station de base pendant la DRX au cours de périodes, la fréquence de la DRX au cours de périodes étant basée sur une configuration UL-DL de référence quelle que soit l'éventuelle reconfiguration de la configuration UL-DL relative à un UE particulier. Dans certains aspects, un UE qui fonctionne en mode de reconfiguration UL-DL peut, lorsqu'il passe en mode DRX, mettre fin de manière autonome à son fonctionnement en mode de reconfiguration UL-DL.
