    Abstract: Apparatuses and methods of beam switching are presented. A beam switch message (BSM) is transmitted to a second device via a first beam set. The BSM includes a command to switch from communication via the first beam set to communication via a second beam set at a switch time. A response message is received from the second device via the first beam set. The response message indicates that the second device received the BSM. A communication is sent to the second device via the second beam set after the switch time if the response message is received.

    Abstract: Un procedimiento (1200, 1300, 1400) de comunicación inalámbrica en un equipo de usuario, que comprende: transmitir (1305) una indicación de su capacidad de traspaso de enlace doble a una estación base de origen, en el que la capacidad de traspaso de enlace doble está asociada con una capacidad de baja latencia; recibir (1205, 1310, 1405) un mensaje de reconfiguración de conexión asociado con un traspaso desde la estación base de origen a una estación base de destino, en el que el mensaje de reconfiguración de conexión comprende información de configuración de control de recursos de radio, RRC, de la estación base de destino; aplicar la configuración de RRC en base, al menos en parte, al mensaje de reconfiguración de conexión recibido; recibir (1210, 1315, 1410) una transmisión de datos de la estación base de origen después de recibir el mensaje de reconfiguración de conexión, en el que la transmisión de datos se recibe en base, al menos en parte, a la indicación; realizar (1215, 1320, 1415) un procedimiento de acceso con la estación base de destino en base, al menos en parte, a recibir el mensaje de reconfiguración de conexión; determinar (1220, 1325, 1420) si el procedimiento de acceso fue correcto; y reajustar (1225, 1330, 1425) una configuración de control de acceso al medio, MAC, reajustar una configuración de control del enlace de radio, RLC, o restablecer una configuración del protocolo de convergencia de datos en paquetes, PDCP, o cualquier combinación de las mismas, en base, al menos en parte, a un procedimiento de acceso correcto.

    IPC: H04W36/00

    Abstract: The apparatus for wireless communication includes a processing system. The processing system is configured to establish a first radio link with a master base station, establish a second radio link with a first cell associated with a secondary base station, wherein the second radio link comprises a SRB, receive a RRC connection reconfiguration signal from the second radio link SRB to enable measurement reports associated with the second radio link, and provide a measurement report to the secondary base station associated with the second radio link using the second radio link SRB.

    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: Aspects described herein relate to establishing communications using multicast in a wireless network. A connection of a User Equipment, UE, with an access point can be established using a cellular radio access technology. An internet protocol request for multicast communications can be transmitted to the access point over the connection, preferably by means of the Internet Group Management Protocol, IGMP. Multicast data can be received from the access point over resources corresponding to over-the-air multicast communications based on the internet protocol request. Assigned radio resources allow the UE to function in discontinuous reception, DRX mode. Mechanisms for ACK/NAK and CQI transmission are also described.
