System information acquisition for reduced capability NR devices

Systems, methods, apparatuses, and computer program products for facilitating explicit latency mode determination in beam switching. One method may include receiving, by a user equipment, at least one beam switch command from at least one network entity. The user equipment may further determine at least one latency and switching mode, and perform beam switch based on the at least one latency and switching mode.

Facilitating explicit latency mode determination in beam switching

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for transferring traffic in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Central Unit-Control Plane (CU-CP) of a first IAB donor transmits, to a second CU-CP of a second IAB donor, a request to transfer target traffic via a Distributed Unit (DU) of the second IAB donor. The request comprises first information of the target traffic. The first CU-CP receives, from the second CU-CP, second information to be used for configuring the target traffic. This solution can improve the reliability and robustness of the IAB communication.

Transferring traffic in integrated access and backhaul communication

In accordance with example embodiments of the invention there is at least a method and apparatus to perform determining by an apparatus information of a list of ranges in a communication network where at least one closed access group cell may be found and where at least one mobile integrated access and backhaul cell may be found; scanning synchronization signal blocks for physical cell identifiers of a candidate cell that are found in both at least one system information block closed access group list or range and at least one system information block mobile integrated access and backhaul list or range; based on the scanning, decoding system information at the candidate cell to verify that the candidate cell is a mobile integrated access and backhaul cell and a closed access group cell; and based on the decoding, enable the apparatus to access the candidate cell for cell reselection.

Method to detect and prioritize closed access group mobile IAB cells

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

A method comprises receiving resource configuration from at least one of a parent node and donor node. The resource configuration comprises information defining at least one resource type for a plurality of links for at least one time and at least one resource. The method comprises allocating, in dependence on the resource configuration, the at least one resource for said at least one time to at least one link of the plurality of links, the at least one link being with one or more child nodes.

Method and apparatus for resource allocation

According to an example embodiment, a method may include transmitting, to at least one integrated access backhaul (IAB) (e.g., relay) node within a wireless network, link capacity threshold information, wherein the at least one IAB node is requested to perform threshold-based reporting of updated link capacity based on the link capacity threshold information; and receiving, from a first IAB node of the at least one IAB node, an updated link capacity report that was triggered (e.g., caused to be generated and/or transmitted) at the IAB node based on a change of available link capacity of the IAB node with respect to the capacity threshold information, the updated link capacity report indicating updated available link capacity of at least one a child backhaul link or at least one access link of the first IAB node.

Threshold-based reporting for efficient admission control support for wireless networks

According to an aspect, there is disclosed a method that includes aligning, by a radio access network node wirelessly connected to at least two parent nodes and to a child node, an uplink reception timing associated with the child node with a downlink reception timing associated with a parent node of the at least two parent nodes.

Timing control in a radio access network node

A method for adjusting transmit timing is disclosed. The method includes determining a reference timing advance value TA, receiving a time offset parameter; and adjusting downlink transmit timing based on i) detected downlink receive timing of radio node and ii) the reference timing advance value TAand the time offset parameter.

Integrated access backhaul node downlink timing adjustment in presence of frequency offset

A distributed unit, DU, of a radio access node configured to operate in a scenario where the DU is one of multiple DUs serving links to a multi-connected entity, acquires a first DU radio resource configuration for the DU, acquires a first link radio resource configuration corresponding to a first link of a multi-connectivity link of a multi-connected entity, wherein the first link is served by the DU, acquires a multiplexing configuration of the multi-connectivity link, and determines availability of at least one radio resource for the multi-connectivity link based on the first DU radio resource configuration, the first link radio resource configuration, and the multiplexing configuration.

Dual connectivity conflict resolution for distributed units

A technique of performing a handover procedure involves providing a proper timing adjustment indication for the UE performing RACH-less HO. Even though the discussion herein is on IAB scenarios and the idea takes an advantage of IAB nodes being in fixed locations (i.e., not moving in the network), it can be applied to UEs in general. The timing adjustment provided in performing a HO in an IAB network according to the improved techniques involves computing a timing advance (TA) to be used by an IAB node prior to executing HO to an alternative serving node. Such a use of a TA may enable a bypassing of a RACH procedure when accessing a cell.

Timing advance for rach-less backhaul handover

Methods and apparatus, including computer program products, are provided In one aspect there is provided a method. The method may include detecting, at a first node, an event; generating, at the first node, a message in response to the detected event; and sending, at the first node, the message to at least a second node to enable the second node to determine at least one of a reliability or an importance of the message. Related apparatus, systems, methods, and articles are also described.
