The embodiments of the disclosure provide a measurement method and apparatus for a terminal, as well as a terminal. The measurement method includes that: a terminal acquires first indication information, the first indication information being for determining a measurement parameter of a dedicated measurement frequency, the measurement parameter of the dedicated measurement frequency being a first measurement parameter and/or a second measurement parameter, and the first measurement parameter being greater than the second measurement parameter.

A method and a device for tight interworking processing, and a base station are provided, which relate to the technical field of communications. The method for tight interworking processing, applied to a first base station, includes: transmitting association information between a first cell and a second cell to a second base station; where the first cell is a cell belonging to the first base station, and the second cell is a cell requested by the first base station and belonging to the second base station.

Techniques and apparatuses are described for secondary cell-user equipment (SC-UE) handovers. In aspects, a base station provides, as a primary cell, primary cell services to a first group of user equipments (UEs) in a first base station-user equipment dual connectivity (BUDC) group. In implementations, the base station determines to perform an SC-UE handover that disconnects a first UE from a first secondary cell-user equipment (SC-UE) that provides a first secondary cell to the first BUDC group and connects the first UE to a second SC-UE that provides a second secondary cell to a second BUDC group. The base station directs the first SC-UE to release the first UE from the first BUDC group, and communicates, as the primary cell, control-plane information or user-plane data with one or more UEs in the first group of UEs that remain in the first BUDC group.

To configure a UE, a DU of a distributed base station receives, from a central unit (CU) of the distributed base station, a UE context request message including a conditional indication related to a conditional procedure (2202); generates, and in response to the conditional indication, configuration information related to the conditional procedure (2220); and transmits, to the CU, a UE context response message including the configuration information (2216).

A terminal apparatus is provided. The terminal apparatus includes a receiver configured to receive a first message from a base station apparatus, and a processing unit configured to modify first data radio bearer configuration configured for the terminal apparatus, based on the first message. A first PDCP entity is reconfigured as a packet data convergence protocol (PDCP) entity for the first data radio bearer. A first secrecy key for a source and a second secrecy key for a target are configured for the first PDCP entity as secrecy keys for the first data radio bearer. In a case that the first message includes first information and second information, the second secrecy key for the target of the first PDCP entity is configured based on the second information. In a case that the first message does not include the first information, the first secrecy key for the source is applied to the second secrecy key for the target of the first PDCP entity.

Methods and systems for easily establishing or switching between wireless connections by sending a Bluetooth Low-Energy (BLE) command from a first BLE enabled device to a second BLE enabled device, where the BLE command causes the second BLE enabled device to attempt to establish a Bluetooth Classic connection with one or more source devices from a list of source devices that have previously been paired with the second BLE device. The first BLE device is configured to obtain or receive the list from the second BLE device, and in response to one or more triggers, send the BLE command. The list of previously paired source devices may be presented to a user via a display screen with touch-screen functionality, and in some examples, may utilize one or more algorithms to intelligently order the available source devices based on a variety of factors.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention provides a method for controlling Wireless Local Area Network (WLAN) aggregation and an associated equipment. The method comprises the following steps of: acquiring, by a first radio access network node, WLAN information about a User Equipment (UE); and, controlling, by the first radio access network node, WLAN aggregation for the UE according to the acquired WLAN information. A second radio access network node decides whether to maintain a WT and/or whether to establish WLAN aggregation for the UE when the UE moves to a first radio access network; and, the second radio access network node transmits information about whether to maintain the WT and/or indication information about whether to establish the WLAN aggregation for the UE. The WT receives UE context reference information transmitted by the first radio access network node; and, the WT indexes a UE context according to the received UE context reference information. With the present invention, the WLAN aggregation performance in a UE mobility scenario can be improved.

A notification method and device for the execution of PDCP data recovery, and same is used to notify an SN to execute a PDCP data recovery process. The notification method for the execution of packet data convergence protocol (PDCP) data recovery comprises: a primary base station sending an inter-node signaling message between the primary base station and a secondary base station to the secondary base station to notify the secondary base station of the execution of a PDCP data recovery process, and the inter-node signaling message is used to instruct the secondary base station to execute a PDCP data recovery process. The method for executing packet data convergence protocol (PDCP) data recovery comprises: the secondary base station receiving the inter-node signaling message sent by the primary base station.

Systems and methods are disclosed for de-prioritizing an LTE anchor cell based on NR cell measurements. A UE may register on a first cell of a first Radio Access Technology (RAT), process a configuration message from a network prioritizing an anchor band of the first RAT, perform a first cell reselection from the first cell to a second cell of the first RAT that is in the anchor band, and perform cell measurements on one or more cells of a second RAT. In response to determining that none of the cell measurements for the one or more cells of the second RAT exceeds a threshold, the UE de-prioritizes the second cell in ranked cell prioritization data and performs a second cell reselection from the second cell of the first RAT to another cell of the first RAT based on the ranked cell prioritization data.
