Title
(EN) TRANSMISSION OF DIFFERENTIAL BROADCAST POSITIONING SIBS FOR REDUCED POWER CONSUMPTION
(FR) TRANSMISSION DE BLOCS D'INFORMATIONS DE SYSTÈME (SIB) DE POSITIONNEMENT À DIFFUSION DIFFÉRENTIELLE POUR UNE CONSOMMATION D'ÉNERGIE RÉDUITE
Abstract
(EN) Positioning assistance data (PAD) is encoded in positioning System Information Blocks (posSIBs) and periodically broadcast by a base station in a differential manner. A PAD element that is different relative to previously broadcast PAD is encoded in a block of posSIB separately from PAD that is unchanged. Another separate block of posSIB includes reference encoding identifying the changed PAD and provides scheduling information. A UE may decode the reference encoding and determine whether the UE has previously decoded the changed PAD. If the UE has previously received the PAD, but has not yet received the new or changed PAD, the UE may receive and decode the block of posSIB with only the changed PAD, thereby increasing efficiency.
(FR) Selon la présente invention, des données d'aide au positionnement (PAD) sont codées dans des blocs d'informations de système de positionnement (posSIB) et diffusées périodiquement par une station de base d'une manière différentielle. Un élément de PAD qui est différent par rapport aux PAD diffusées précédemment est codé dans un bloc de posSIB séparément des PAD qui sont inchangées. Un autre bloc séparé de posSIB comprend un codage de référence identifiant les PAD modifiées et fournit des informations de planification. Un équipement utilisateur (UE) peut décoder le codage de référence et déterminer si l'UE a ou non décodé précédemment les PAD modifiées. Si l'UE a reçu précédemment les PAD, mais n'a pas encore reçu les nouvelles PAD ou les PAD modifiées, l'UE peut recevoir et décoder le bloc de posSIB avec uniquement les PAD modifiées, permettant ainsi d'augmenter l'efficacité.
