A method and apparatus for relaxation of mobility condition based on serving cell quality is provided. A wireless device, which has been configured with conditional mobility, performs a conditional mobility to a target cell by using a mobility condition related to the target cell upon detecting a radio link problem on a serving cell.

Systems and methods for performing signaling transmission or exchange for wireless sidelink relay communications are described. In one embodiment, a method performed by a first network node is disclosed. The method comprises: obtaining, from a wireless communication device, a first indication information indicating that the wireless communication device supports a sidelink relay communication involving the wireless communication device; transmitting, to a second network node, a second indication information generated based on the first indication information; and obtaining, from the second network node, a third indication information indicating whether the wireless communication device is authorized to perform the sidelink relay communication.

A method and device in a node for wireless communications. A node receives first information and monitors a control signaling candidate in a target control signaling candidate set; the first information determines a target cell, and the target cell schedules a characteristic cell; a first control signaling candidate belongs to a sub-band in the first sub-band set in frequency domain; a first time window comprises a control signaling candidate in time domain; a serving cell to which a sub-band comprised in the first sub-band set belongs belongs to a scheduling cell set; an SCS of a subcarrier comprised in the first sub-band set is equal to a first SCS; the first SCS is used to determine the first time window; a number of monitoring(s) performed on a control signaling candidate is not greater than a first threshold value. The application improves the performance of scheduling channels.

A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) associated with a primary link and a non-primary link determines that the non-primary link is unavailable, and transmits, on only the primary link, a frame carrying an indication of the unavailability of the non-primary link. The NSTR softAP MLD may set a Do Not Transmit (DNT) bit to a value of 1 and may operate as a single-link device on the primary link based on the unavailability of the non-primary link. In some instances, the NSTR softAP MLD determines that the non-primary link is available while operating as the single-link device on the primary link, resets the DNT bit based on the availability of the non-primary link, and transmits the reset DNT bit in another frame on only the primary link.

The present disclosure provides a method for conditional handover by a user equipment (UE) in a 5G communication network. The method may include: receiving, by the UE, a conditional handover command, and an associated condition from the source cell; receiving, by the UE, a plurality of target cell configurations, from the source cell, having details for a plurality of target cells meeting a conditional handover criterion; evaluating, by the UE, the received associated condition for the conditional handover; and assigning priority to the received target cells configured in the conditional handover during the cell selection procedure. The method may include selecting one target cell for conditional handover from among the plurality of target cells based on the assigned priority.

A pre-5th-Generation (5G) or 5G communication system is provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long term evolution (LTE). The method for operating a primary base station in a wireless communication system is provided. The method includes transmitting, to a secondary base station, an addition request message. The addition request message carries information of a secondary cell group (SCG) split bearer. The method further includes receiving, from the secondary base station, a response message of the addition request message.

A radio access network (RAN) node can receive, from a user equipment (UE), a request to establish a session associated with a low-latency service level agreement (SLA). The session can be mapped to a radio bearer associated with a network slice configured to support the low-latency SLA, wherein the network slice can include a RAN portion and a core network portion that are co-located at a RAN edge to support the low-latency SLA. The RAN node can provide information related to the radio bearer to a distributed unit (DU) associated with the RAN portion of the network slice and route traffic associated with the session through the network slice configured to support the low-latency SLA via the radio bearer mapped to the session. As such, the session can have a context maintained in the RAN portion and the core network portion of the network slice.

The described technology is generally directed towards contextual network function selection and transfer. Techniques disclosed herein can be implemented at core network access management functions (AMFs). An AMF can obtain user equipment context information via a gNodeB (gNB). Rather than causing a local default session management function (SMF) and user plane management function (UPF) to process user equipment communications, the AMF can use a mapping function to identify, based on the user equipment context information, a proximal SMF and corresponding UPF which have a nearer proximity to the user equipment. The AMF can facilitate selection of the proximal SMF and UPF for the user equipment, and the AMF can transfer the user equipment context information to a proximal AMF that is better situated to serve the proximal SMF and UPF. By facilitating transfer to the proximal SMF and UPF, communication latency experienced by the user equipment can be reduced.

A method performed by a user equipment (UE) and a UE for managing cell selection in a cellular network based on early measurement feature is provided. The method includes detecting that a signal strength of a first cell to which the UE is connected is below at least one threshold parameter, identifying a plurality of secondary cells, in the vicinity of the UE, having signal strengths greater than the at least one threshold parameter and supporting early measurement features, wherein the plurality of the secondary cells include at least one New Radio (NR) cell, and selecting the at least one NR cell from the identified plurality of secondary cells for connecting to the cellular network.

Apparatus and methods for guaranteeing a quality of experience (QoE) associated with data provision services in an enhanced data delivery network. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coax infrastructure) is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) via a common service provider. In one exemplary implementation, “over-the-top” voice data services may enable exchange of voice traffic with client devices in the aforementioned network. A distribution node may use a detection rule to identify received packets as voice traffic, and cause a dedicated bearer to attach to the default bearer, thereby enabling delivery of high-quality voice traffic by at least prioritizing the identified packets thereafter and sustaining the delivery even in a congested network environment, and improving the quality of service (QoS) and QoE for the user(s).
