    Abstract: Methods, systems, and devices for wireless communication are described. A device—such as a base station or user equipment (UE)—may transmit a demodulation reference signal (DMRS) including signaling information in addition to channel estimation information. To improve reception of the DMRS signaling information, the transmitting device may employ data protection techniques to the signaling information and modify a data payload transmitted in the physical data channel associated with the DMRS. In one aspect, the transmitting device may modify cyclic redundancy check (CRC) bits in the payload to include verification for the signaling information. In another aspect, the transmitting device may determine a scrambling code based on the signaling information, and may scramble the payload based on the scrambling code.

    Abstract: Aspects of the present disclosure provide methods and apparatus for improving UL-based mobility. As described herein, a UE may determine it has failed to decode a first keep alive (KA) signal during a wake period of a discontinuous receive (DRx) cycle and may extend the wake period to monitor for a second KA signal, in response to the determination. An access network controller may select, while a (UE) is currently served by a first transmit/receive point (TRP), a second TRP to serve the UE, configure the first TRP to transmit a first keep alive (KA) signal, in response to a chirp signal received from the UE, and configure the second TRP to transmit a second KA signal after the first KA signal transmitted by the first TRP.

    Abstract: Various aspects described herein relate to dynamic uplink antenna port management. A user equipment (UE) may receive reference signal configuration information from a base station. The UE may configure one or more uplink antenna ports based on the received reference signal configuration information and transmit one or more reference signals to the base station on the one or more uplink antenna port. The UE may receive uplink configuration information for one or more data channels and/or one or more control channels. The UE may configure one or more uplinks antenna ports based on the uplink configuration information and may transmit one or more uplink signals on the one or more data channels and/or one or more control channels. The uplink configuration information may be based at least one the one or more reference signals transmitted to the base station.

    Abstract: L'invention porte sur des procédés de fonctionnement d'appareils de gestion de mobilité qui consistent à identifier une cellule cible à titre de candidate pour un ensemble actif. Les procédés de fonctionnement des appareils consistent en outre à déterminer qu'une condition de déclenchement d'ajustement existe, la condition de déclenchement d'ajustement déclenchant un ajustement d'une valeur de positionnement temporel qui indique un instant d'envoi d'un message d'ajout de cellule cible à une cellule de desserte. En outre, les procédés de fonctionnement des appareils consistent à envoyer le message d'ajout de cellule cible comprenant la cellule cible à la cellule de desserte sur la base de la détermination d'existence de la condition de déclenchement d'ajustement.
