Abstract: A method for improving link efficiency in multicast transmissions is described. A data packet is sent to a multicast server. The data packet is processed. A copy of the data packet is transmitted from the multicast server to a multicast internet protocol (IP) address associated with one or more access terminals. The copy of the data packet is multicast to each of the one or more access terminals using a channel dedicated for multicast traffic that is associated with each of the one or more access terminals.

Abstract: Techniques are disclosed for handover of a user equipment (UE) from a serving base station to a target base station. A target base station may use one or more directional beams to establish wireless communication links with UEs within a coverage area of the target base station. Directional beams may create a narrow-beam, high-bandwidth connection with a UE in a limited geographic area. Handover procedures include some latency between when a target base station dedicates resources to a UE and when the UE executes a communication via those dedicated resources. To compensate for latencies in a handover procedure and for the geographic limitations of directional beams, a target base station may assign multiple directional beams to the UE during a handover procedure. Each directional beam may be associated with access parameters used by the UE to generate messages (e.g., a RACH message) during the handover procedure.

Abstract: Se divulgan técnicas para la entrega de un equipo de usuario (UE) desde una estación base de servicio a una estación base objetivo. Una estación base objetivo puede usar uno o más vigas direccionales para establecer enlaces de comunicación inalámbrica con UE dentro de un área de cobertura de la estación base objetivo. Las vigas direccionales pueden crear una conexión de ancho de banda de haz estrecho y alto con un UE en un área geográfica limitada. Los procedimientos de entrega incluyen cierta latencia entre cuando una estación base objetivo dedica recursos a un UE y cuando el UE ejecuta una comunicación a través de esos recursos dedicados. Para compensar las latencias en un procedimiento de entrega y las limitaciones geográficas de los haces direccionales, una estación base objetivo puede asignar múltiples vigas direccionales al UE durante un procedimiento de transferencia. Cada haz direccional puede estar asociado con los parámetros de acceso utilizados por el UE para generar mensajes (por ejemplo, un mensaje RACH) durante el procedimiento de entrega.
