A Gap configuration method, User Equipment (UE), and a network device are provided. The Gap configuration method includes: receiving first enabling information from a network device, where the first enabling information is used to indicate whether a first need configuration of a first Gap is enabled, the first Gap is a Gap including at least one of N Gap types, and N is a positive number; sending first request information to the network device in a case that the first enabling information indicates that the first need configuration is enabled, where the first request information is used to request a first target Gap, and a Gap type of the first target Gap is at least one of the N Gap types; and receiving first configuration information from the network device, where the first configuration information is used to configure the first target Gap.

This application provides a receive chain enabled state switching method and a first multi-link device. The method includes: A first multi-link device receives, by using a first link, a first frame sent by a second multi-link device to the first multi-link device; and the first multi-link device makes one or more second links be in a multi-receive-chain enabled state, where the second link is a link that is between the first multi-link device and the second multi-link device and that is different from the first link. The method provided in this application helps the second multi-link device perform data transmission with the first multi-link device on the second link in a timely manner by using a plurality of spatial flows. This application may be applied to a plurality of Wi-Fi systems supporting an 802.11 standard, for example, the 802.11be standard.

This application discloses a multicast transmission method. The multicast transmission method includes: a first network device receives a first data packet and first indication information, where the first indication information indicates a sequence of the first data packet in at least one data packet; the first network device sets a sequence number of a first protocol layer of the first data packet based on the first indication information; and the first network device sends the first data packet to a terminal device. In this way, all data packets received by the terminal device include corresponding sequence numbers of the first protocol layers.

This disclosure provides systems, methods and apparatus for a signaling mechanism associated with activating a secondary cell (SCell) for uplink control information (UCI), including under circumstances in which the SCell is deactivated and belongs to a timing advance group (TAG) lacking a valid timing advance (TA) value. In one aspect, a user equipment (UE) and one or more components of a network entity may employ a signaling mechanism for establishing an SCell as a PUCCH-SCell in scenarios in which the PUCCH-SCell belongs to a secondary TAG (sTAG) lacking a valid TA value. The signaling mechanism may include signaling to directly provide the network entity with beam measurement information associated with one or more SCells of the sTAG or may include singling that the network entity may use to derive the beam measurement information associated with the one or more SCells of the sTAG.

The 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 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 disclosure relates to a method and a device for quickly recovering a connection to a network in a next-generation mobile communication system when the connection to the network fails.

Systems, methods, apparatuses, and computer program products for individual delivery of location-based multicast services are provided. One method may include receiving, by a session management node, information that a user equipment is participating in a multicast session, determining that the UE is served by a radio access node that does not support multicast sessions, and determining that the multicast session is only to be delivered to one or several service areas. In response to determining that the UE is served by a radio access node not supporting multicast and that the multicast session is only to be delivered to one or several service areas, the method further comprises subscribing to at least one notification from at least one access and mobility management node.

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.
