Provisioning and communicating physical signals and channels in NR networks having a first subset of transmit and receive points that use a first cell ID and a second subset of transmit and receive points that use a second cell ID. Operations include transmitting from, and receiving from, a first transmit and receive point a first signal or channel wherein the first signal or channel is based on a first user equipment (UE) specific parameter assigned via the first subset of transmit and receive points and transmitting from, and receiving from, the first transmit and receive point the plurality of transmit and receive points a second signal or channel wherein the second signal or channel is based on a second UE specific parameter assigned via the second subset of transmit and receive points. A transmit and receive point and a UE for implementing the operations are also disclosed.

Methods, systems, and devices for wireless communications are described. a first donor node may serve a relay node, which in turn may serve a child node. The first donor node may determine to transfer (e.g., via a handover procedure) the relay node to a second donor node. The first donor node may transmit a first context transfer request for the relay node to the second donor node, and may transmit a second context transfer request for the child node of the relay node to the second donor node. The first donor node may indicate a correlation between the two context transfers. The second donor node may identify the correlated context transfers, and may successfully perform a migration procedure for the relay node and any descendent devices or nodes based on the correlated context transfers.

A radio access network handover method of a base station in a 5G radio access network (5G-RAN) is are disclosed. The method comprising: determining handing over a user equipment (UE) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN); transmitting a handover requirement message to an Access and Mobility Management Function (AMF); receiving a handover command message from the AMF and transmitting the handover command message to the UE, the handover message such that the UE is handed over from the 5G-RAN to the E-UTRAN; and performing indirect data forwarding to a base station in the E-UTRAN.

A computer implemented method allocates wireless network and adaptive video streaming resources in environments with high device density. The network has one or more access points and at least one user device. The stages of the method include obtaining the information from radio access network or video service telemetry; generating a resource allocation list between each user device and at least one channel with an associated representation index, distributing the resource allocation list, performing at least one handover and at least one video rate recommendation.

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. Embodiments herein provide a method for performing a routing ID (RID) update in user equipment (UE) in a wireless communication network.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a central or management entity of an integrated access and backhaul (IAB) network may receive a report indicating one or more of a failure associated with a communication link associated with an IAB node included in the IAB network or a quality of service (QoS) associated with the communication link. The apparatus may modify a topography of the IAB network or routing within the IAB network when the report indicates the failure associated with the communication link. The apparatus may verify a QoS associated with the IAB network when the report indicates the QoS associated with the communication link. Numerous other aspects are described.

An apparatus and method are provided for steering a PDU session associated with traffic routed to a selected UPF. The method includes receiving, from an AF entity, a first message including information for selecting a UPF entity for traffic routing of a terminal and information on a spatial condition associated with a location of the terminal; transmitting, to an SMF entity, a second message to receive information associated with the location of the terminal indicating that the terminal entered or left a specific area, the specific area being determined by the PCF entity based on the spatial condition; receiving, from the SMF entity, a third message including the information associated with the location of the terminal; and transmitting, to the SMF entity, a fourth message based on the information associated with the location of the terminal included in the third message, the fourth message including the information for selecting the UPF entity for traffic routing of the terminal.

The present invention relates to an IPv6 wireless sensor network node mobility management method based on RPL routing protocol. The present invention achieves the following: first, placing an RSSI in an ACK frame so as to detect the mobile state of a node and improve the accuracy of mobile detection; second, on the premise of compatibility with an original RPL routing protocol, improving the options for DIS and DAO in selecting the optimal parent node and updating a routing table; and finally, designing a cache method to prevent messages sent to the mobile node from being lost in the process of moving, and designing a new 6LoWPAN header so as to complete message caching.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.
