Abstract:
PROBLEM TO BE SOLVED: To provide a method and device for performing efficient location updates of an MTC (machine type communication) terminal by providing a terminal specific idle mode timer and location update types with consideration for mobility types and traffic patterns of the MTC terminal in an MTC environment.SOLUTION: A method of allowing a terminal to perform a location update in an idle mode in a wireless access system comprises the steps of: receiving, from a base station, a machine-to-machine (M2M) terminal specific idle mode timer; and performing a location update based on the received M2M terminal specific idle mode timer. The M2M terminal specific idle mode timer represents length of the maximum interval between location updates when the terminal is in the idle mode.
Abstract:
Un método de sondeo de un punto de acceso, AP, para recibir información de retroalimentación incluyendo un estado del canal de enlace descendente, DL, en un sistema de LAN inalámbrica, WLAN, comprendiendo el método: transmitir una trama de anuncio, NDPA, de paquete de datos nulo NDP, que anuncia la transmisión de una trama de NDP; transmitir la trama de NDP; transmitir una trama de activación, que incluye información de asignación de recurso referida a una unidad de recurso asignada a una estación STA; y recibir una trama de retroalimentación que incluye una información de retroalimentación que incluye el estado de canal de DL mediante la transmisión de múltiples usuarios, MU, de enlace ascendente, UL, mediante la unidad de recurso asignada, en el que la información de retroalimentación se genera en base a la trama de NDP, en el que la información de retroalimentación se notifica para cada una de una pluralidad de granularidades de frecuencia, FG, con respecto a un ancho de banda de recepción parcial de la trama de NDP recibida, en el que el ancho de banda de recepción parcial es un ancho de banda de objetivo de informe, en el que cada una de la pluralidad de FG es una unidad de informe y en el que cada una de la pluralidad de FG tiene un menor tamaño que el ancho de banda de recepción parcial.
Abstract:
Disclosed is a method for performing a carrier switching operation in the perspective of a terminal in a multicarrier system, the method including establishing an enhanced-multicast broadcast service (E-MBS) service connection with a base station for E-MBS service reception, sending an E-MBS report message to the base station in the E-MBS service connected state with the base station, the E-MBS report message including connection information related to E-MBS channels, which the terminal is receiving or E-MBS channels, which the terminal intends to receive, receiving an E-MBS response message from the base station in response to the E-MBS report message, and performing a carrier switching operation for the E-MBS service reception based upon unicast available interval information included in the E-MBS response message.
Abstract:
The present document relates to a wireless communication system and, more particularly, to a method for performing retransmission in a wireless LAN system to which transmission opportunity (TXOP) sharing is applied, and a device therefor. To this end, a station transmits an initial transmission frame including primary access category (AC) information and secondary access category (AC) information; and when there is no response to the secondary AC information of the initial transmission frame, reconfigures a back-off timer value for the secondary AC information and retransmits the secondary AC information according to the reconfigured back-off timer value.
