Abstract

Embodiments include methods for a first network node (e.g., eNB) of a wireless network (e.g., EPS). Such methods include sending (610), to a second network node of the wireless network, a request to retrieve context information associated with a user equipment (UE) that has been or is being handed over from the second network node to the first network node. Such methods include receiving (620) the context information associated with the UE from the second network node. Specifically, the context information includes an indication of whether the UE has an active IP Multimedia System (IMS) voice call that was subject to a first inter-system handover from a 5G System (5GS) to the wireless network. Other embodiments include complementary methods for the second network node, as well as network nodes configured to perform such methods.

Abstract

There is provided a referencing mechanism for messages (e.g., SEI messages) in order to reduce the bit cost when different versions of messages (e.g., SEI messages) are used in an arbitrary manner in the bitstream, e.g. in an alternating way in the bitstream. In embodiments, two SEI messages are used to express a functionality. In the first SEI message, syntax elements specifying the functionality is provided. The first SEI message may also have an identifier value, which uniquely identifies the instance of that particular SEI message. The second SEI message, typically much smaller and sent more frequently than the first SEI message, is used to reference the first SEI message in order to apply the functionality of the first SEI message to a part of the bitstream determined by the persistence scope of the second SEI message, e.g. for the picture or subpicture it was sent with.

Abstract

Techniques are provided to enable radio devices to operate using irregular bandwidths that are not defined channel bandwidths by the applicable RAT. A UE designed to limit emissions outside the irregular bandwidth block but within the channel bandwidth can indicate this capability when it accesses the network. When a UE indicates a capability to use irregular bandwidths, the network can schedule the UE in an irregular bandwidth block while blanking the part of the channel bandwidth outside the irregular bandwidth block in order to maximize the use of the irregular bandwidth block. If a UE does not indicate capability for using irregular bandwidth blocks, the network can schedule the UE in a defined bandwidth inside the irregular bandwidth block provided there is a defined channel bandwidth less than the irregular block bandwidth.

Abstract

According to some embodiments, a method performed by a wireless device for transmitting on a plurality of antennas comprises signaling, to a network node, a wireless device power transmission capability. The wireless device power transmission capability identifies a power ratio value of a plurality of power ratio values that the wireless device supports for transmission of a physical uplink channel. Each value of the plurality of power ratio values corresponds to a transmission power capability and to a number of antenna ports. A power ratio refers to a ratio relative to a maximum power the wireless device is rated to transmit. The method further comprises transmitting a physical uplink channel using the 0 number of antenna ports with a power scaled at least by the power ratio value.

Abstract

Methods, donor DU nodes and donor CU nodes, and computer programs are provided for allocating internet protocol, IP, addresses. A request is received at a donor DU node to allocate an IP address for a wireless node. The IP address is allocated for the wireless node by the donor DU node and the IP address is transmitted towards the wireless node. The donor CU node receives a message from a wireless node requesting an IP address. Responsive to receiving the message from the wireless node requesting an IP address, the donor CU node transmits an allocation message to a donor DU node to request IP address allocation for the wireless node.

Abstract

Embodiments includes methods for a centralized unit (CU) in an integrated access backhaul (IAB) network. Such methods include determining a first identifier of a first backhaul radio link control (BH RLC) channel between first and second nodes in the IAB network. The second node is a child node of the first node. Such methods include sending, to the second node, a second request to setup a second BH RLC channel between the second node and a third node in the IAB network. The third node is a child node of the second node, and the second request includes the first identifier for association with the second BH RLC channel. In some embodiments, at least one data radio bearer between a user equipment (UE) and the CU is associated with both the first and second BH RLC channels. Other embodiments include complementary methods for an intermediate node in the IAB network.
