A first communication device determines whether a second communication device is in a power save mode with respect to a first communication link among a plurality of communication links that correspond to respective frequency segments, and determines whether the second communication device is in a power save mode with respect to a second communication link among the plurality of communication links. The second communication device is permitted to be in the power save mode with respect to the second communication link when the second communication device is not in the power save mode with respect to the first communication link, and vice versa. The first communication device communicates with the second communication device in accordance with the power save modes of the second communication device with respect to the first and second communication links.

A method for an apparatus operating in a wireless communication network. The method includes: determining at least one functional safety indicator that indicates at least whether associated data, especially V2X data that comprises at least one of a vehicle operating parameter and a roadway event, or industrial data that comprises a machine operating parameter, or building technology data that comprises building operational data, is relevant according to at least one safety integrity level; and transmitting the data along with the at least one determined functional safety indicator.

The present application provides a method and a device in nodes used for wireless communications. A first node receives first configuration information, the first configuration information being non-unicast, and the first configuration information indicating K sub-bearers; herein, K is a positive integer greater than 1; for any higher-layer packet transmitted respectively through the K sub-bearers, sequence numbers of the higher-layer packet in the K sub-bearers are the same; a first sub-bearer is one of the K sub-bearers, and a higher-layer packet transmitted in any of the K sub-bearers is transmitted through the first sub-bearer. The present application enables the users to acquire by broadcast configuration information of sub-bearers transmitting the same MBMS on different nodes or CGs, so that the same MBMS can be acquired from multiple nodes simultaneously with decreased traffic interruptions caused by inter-node mobility.

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may determine a preference of the UE for a termination point between a core network and a radio access network (RAN), the core network and the RAN supporting communications for the UE via at least one or a first cell and a second cell each associated with a multi-connectivity mode of the UE. The UE may transmit, to a base station, an indication of the preference of the UE for the termination point. In some cases, the base station may determine the termination point based on receiving the indication of the preference of the UE, and the base station may transmit a message indicating a configuration for the multi-connectivity mode to the UE, the configuration indicating the determined termination point.

Systems, devices, and techniques described herein relate to migrating a communication session from a path including a stressed user plane function (UPF) to a path including a replacement UPF. A communication session may traverse a first path including the first UPF. After establishing the communication session, the first UPF may be determined to be stressed. In response, the communication session can be proactively migrated to a second path including a second UPF. According to various implementations, the existing communication session can be maintained during the migration, thereby substantially eliminating interruptions caused by the stressed first UPF.
