Title (EN) MESSAGE-BASED EXCHANGE OF ACCESS POINT PILOT SIGNATURE INDICATORS
(FR) ÉCHANGE BASÉ SUR DES MESSAGES D'INDICATEURS DE SIGNATURES PILOTES DE POINT D'ACCÈS
Abstract: front page image
(EN)An access point is identified based on a plurality of pilot signatures (pseudo-random noise, PN, spreading codes or scrambling codes). Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature (e.g. PN offset or PN phase). For example, an access point may use one PN offset to generate and transmit a pilot signal and transmit a different message that identifies (includes) at least another PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot- related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal. In a certain aspect of the invention, a femto management system maintains a pool of PN offsets that may be allocated to femtocells mapping between PN offsets and cell -IDs may be carried out.
(FR)Un point d'accès est identifié sur la base d'une pluralité de signatures pilotes. Ici, en plus d'émettre un signal pilote qui est codé (par exemple, étalé/embrouillé) à l'aide d'une signature pilote particulière, un point d'accès envoie un message qui inclut au moins une indication d'au moins une autre signature pilote. Un point d'accès peut, par exemple, utiliser un décalage de bruit pseudo-aléatoire pour générer un signal pilote et envoyer un message identifiant au moins un autre décalage de bruit pseudo-aléatoire. Un terminal d'accès recevant le signal pilote et le message peut alors générer un rapport pilote qui identifie toutes ces signatures pilotes. Lors de la réception d'un message de transfert incluant ces informations pilotes, une entité de réseau cible ayant connaissance des signatures pilotes affectées à ce point d'accès peut alors identifier précisément le point d'accès comme cible pour le transfert du terminal d'accès.
