Abstract
(EN)
Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support aperiodic and cross component carrier PRSs. Generally, the described techniques provide for receiving a dynamic trigger indicating that a UE is to monitor for one or more downlink positioning reference signals (PRSs). The UE may generate a timing measurement for the one or more downlink PRSs, and may transmit a measurement report that indicates the timing measurement to a transmission/reception point. A UE may also transmit a capability indicator, indicating that the UE is capable of maintaining phase coherence for a PRS that spans multiple component carriers, receive control signaling that indicates multiple component carries on which the PRS is phase coherent, generate a timing measurement for the PRS based on the control signaling, and transmit a measurement report that indicates the timing measurement to the transmission/reception point.

L'invention concerne des procédés, des systèmes et des dispositifs destinés aux communications sans fil. Les techniques de la présente invention concernent des procédés, des systèmes, des dispositifs et des appareils améliorés qui prennent en charge des signaux de référence de positionnement (PRS) de porteuses composantes croisées et apériodiques. D'une manière générale, les techniques décrites permettent de recevoir un déclencheur dynamique indiquant qu'un UE doit faire l'objet d'une surveillance relative à un ou plusieurs signaux de référence de positionnement (PRS) de liaison descendante. L'UE peut générer une mesure de synchronisation pour le ou les PRS de liaison descendante, et peut transmettre un rapport de mesure qui indique la mesure de synchronisation à un point d'émission/réception. Un UE peut également transmettre un indicateur de capacité, indiquant que l'UE est susceptible de maintenir une cohérence de phase pour un PRS qui s'étend sur de multiples porteuses composantes, de recevoir une signalisation de commande qui indique de multiples porteuses composantes sur lesquelles le PRS est cohérent en phase, de générer une mesure de synchronisation pour le PRS sur la base de la signalisation de commande, et de transmettre un rapport de mesure qui indique la mesure de synchronisation au point d'émission/réception.
