It is provided a method, comprising monitoring if an assignment packet is received by a new node from a parent node; setting, if the assignment packet is received, a new value of an identifier for determining if a first packet of a first layer protocol is intended for the new node; wherein the assignment packet comprises the new value of the identifier; the assignment packet is a packet of the first layer protocol; the assignment packet comprises a header of the first layer protocol.

Address assignment

There is disclosed method for a network apparatus, the method comprising configuring the network apparatus to use a first transmit and/or receive pattern selected from a plurality of available transmit and/or receive patterns for performing discovery procedures with another network apparatus, wherein the first transmit and/or receive pattern is selected from said plurality in dependence on at least the mobility of said network apparatus and/or on the relative mobility of said network apparatus to said another network apparatus.

Communication system

Systems, methods, apparatuses, and computer program products for the configuration of user device(s) for reception of point-to-multipoint transmission are provided. One method may include receiving, at a user equipment, a configuration for point-to-multipoint reception of a group-common transport channel. The configuration may include a group-common signaling configuration for a group of user equipment. The method may also include receiving, at the user equipment, a point-to-multipoint reconfiguration message using the group-common signaling configuration on the group-common transport channel from a device (e.g., a network node). The point-to-multipoint reconfiguration message may include an updated point-to-multipoint configuration. The method may then include receiving point-to-multipoint data, from the device on the group-common transport channel, based on the updated point-to-multipoint configuration.

Embodiments of the disclosure provide a method, device and computer readable medium for centralized unit switch. According to embodiments of the present disclosure, the DU transmits identity information of a target CU/DU to the source CU for the CU switch. The target CU does not need to initiate context setup procedure to set up context for the terminal device. Thus, the switch is implemented with minimized signaling and interruption in the data connection and the switched is completed faster by avoiding the unnecessary F1 AP context setup.
