Title (EN) PHYSICAL CELL IDENTIFICATION CHANNEL (PCICH)
(FR) CANAL D'IDENTIFICATION DE CELLULE PHYSIQUE (PCICH)
Abstract:
(EN) Aspects of the present disclosure provide for the transmission of a cell identifier of a serving cell to a user equipment (UE). A Physical Cell Identification Channel (PCICH) is defined for carrying the cell identifier of the serving cell within an uplink-based mobility framework. In some examples, the PCICH may be transmitted in response to a trigger event that requires the user equipment to have knowledge of the cell identifier. For example, the UE may require the cell identifier to demodulate signals received from the serving cell and facilitate transmission and/or reception of user data traffic with the serving cell.
(FR) La présente invention porte, selon des aspects, sur la transmission d'un identifiant de cellule d'une cellule de desserte à un équipement utilisateur (UE pour User Equipment). Un canal d'identification de cellule physique (PCICH pour Physical Cell Identification CHannel) est défini pour transporter l'identifiant de cellule de la cellule de desserte dans une structure de mobilité basée sur la liaison montante. Selon certains exemples, le canal PCICH peut être transmis à la suite d'un événement déclencheur qui nécessite que l'équipement utilisateur ait connaissance de l'identifiant de cellule. Par exemple, l'équipement utilisateur peut demander à l'identifiant de cellule de démoduler des signaux reçus de la cellule de desserte et de faciliter la transmission et/ou la réception d'un trafic de données d'utilisateur avec la cellule de desserte.
