A base station transmits parameters of cells grouped into control channel groups comprising: a primary control channel group; and a secondary control channel group. The secondary control channel group comprises: a control channel secondary cell with a secondary control channel; and a secondary cell. A radio link issue with the control channel secondary cell of a wireless device is detected. At least one command to deactivate the secondary cell for the wireless device is transmitted in response to the radio link issue.

A method and apparatus for discarding a buffered data in a wireless communication system is described. A central unit (CU) user plane (UP) of a gNB receives a buffered data discard indication from a CU-control plane (CU-CP) of the gNB, and discards buffered data for a user equipment (UE) based on the buffered data discard indication. Even after discarding the buffered data, UE context is still kept. The CU-CP is a logical node constituting the gNB that hosts a radio resource control (RRC) protocol and a packet data convergence protocol (PDCP)-C protocol, and the CU-UP is a logical node constituting the gNB that hosts a PDCP-U protocol.

The present disclosure relates to a communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention provides a method of a SMF entity in a wireless communication system. The method comprises identifying whether to deactivate an UP connection of a first PDU session of one or more established PDU sessions, identifying whether the first PDU session supports an UP optimization based on the identification, and transmitting, to an AMF entity, a first message for deactivating the UP connection.

A communication device comprises a first communication unit and a second communication unit of a same type as that of the first communication unit. The first communication unit or the second communication unit is configured to transmit, after wireless connection to an electronic apparatus is established, a waiting instruction signal for instructing the electronic apparatus to enter a state in which the electronic apparatus waits for a connection request.

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QoS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

New methods are proposed to detect misbehaving UEs based on 5GS. The methods allow the network to react accurately and efficiently to deal with misbehaving UE(s).

This application discloses a Bluetooth reconnection method, and relates to the field of short-range wireless communications technologies. The method includes: When a charging case is closed, a first earbud breaks a Bluetooth connection, where the first earbud stores a Bluetooth address of a terminal and a Bluetooth address of a second earbud. When the charging case is opened, the charging case accommodates only the first earbud, and a first preset condition is met, the first earbud sends a first paging request to the second earbud based on the Bluetooth address of the second earbud. The first preset condition is that the Bluetooth connection includes a Bluetooth connection between the first earbud and the second earbud. In this way, reconnection duration of the first earbud when the charging case is opened can be reduced.
