Abstract: A quantity of antennas included in the antenna assembly is greater than a quantity of receive antennas supported by customer premises equipment (CPE). Therefore, when a network changes, the CPE may select, from a plurality of antennas included in the antenna assembly, a quantity of antennas with relatively good data transmission performance as receive antennas, where the quantity is the same as the quantity of receive antennas supported by the CPE. That is, the CPE may not need to adjust directions of antennas, but select, from a redundant quantity of set antennas, antennas with relatively good receiving performance to ensure that the CPE is aligned with a direction with relatively good signal quality.

Abstract: The present invention discloses a method and device for scheduling terminals based on the measurement gap. The method comprises: when the system side needs to schedule a terminal in a measurement state of measurement gap, not only judging whether the downlink scheduling information or the uplink authorization information of the terminal is sent during the period of measuring the measurement gap, but also judging whether the downlink scheduling feedback, the uplink data feedback or the uplink data corresponding to the uplink authorization is sent during the period of measuring the measurement gap, and scheduling the terminal normally when none of the above information is sent during the period of measuring the measurement gap; the device comprises a judging module, a scheduling module and a terminal information acquisition module. The present invention can simplify the processing for the terminal and save the resources of the system.

Abstract: A method and apparatus for handover between base stations are disclosed.

Abstract: The present invention discloses a method and system for transmitting an ETWS primary notification message. After paging a terminal through a paging message containing ETWS message indication information, a base station schedules the ETWS primary notification message as user data in a sub-frame subsequent to a sub-frame with the paging message and generates control information containing an ETWS ID and resource information on a DL-SCH assigned for the primary notification message of the ETWS; the base station sends the control information over a PDCCH and sends the primary notification message of the ETWS over the DL-SCH based on the control information; and after receiving the paging message, the terminal detects and analyzes the control information containing the ETWS ID by monitoring the PDCCH to obtain the resource information thereof, and receives the ETWS primary notification message on corresponding resources of the DL-SCH based on the resource information.

Abstract: The present disclosure provides an earthquake and tsunami warning system and a transmission method for a primary notification message thereof. The transmission method includes: a base station pages all terminals via a paging message containing indication information of an earthquake and tsunami warning system (ETWS) message, and transmits security information of an ETWS primary notification message via the resource prearranged with the terminals, and basic information of the ETWS primary notification message is transmitted within the paging message or via the prearranged resource; the terminals receive the security information of the ETWS primary notification message via the prearranged resource after receiving the paging message containing indication information of the ETWS message, and obtains the basic information of the ETWS primary notification message from the paging message or receives the basic information of the ETWS primary notification message via the prearranged resource.
