A method comprises when a first data unit is to be transmitted on a plurality of different transmission paths determining, in dependence on at least one condition or indication if a) a copy of the first data unit is to be transmitted on one or more of the plurality of different transmission paths and/or if b) one or more coded data units are to be transmitted on one or more of the plurality of different transmission paths, a coded data unit being provided by coding the first data unit with at least one other preceding data unit. The method further comprises in dependence on said determining, causing the transmitting of one or more copies of the first data unit and/or one or more coded data units on respective ones of the plurality of different transmission paths.

Apparatus, method, and computer program

UE positioning is added by use of a reconfigurable reflecting surface (e.g., IRS). The IRS is configured to adjust elements of the surface. The configuration may include signal switching on or off, signal phase, group delay, or signal amplitude. Positioning reference signal transmissions are performed that have line of sight to the UE and that reflect off the IRS. The UE takes measurements for the transmissions and can determine measurement(s) of angle of arrival or time of arrival or reference signal received power, and/or determine a channel estimation. Multiple methods are proposed to provide UE positioning.

UE positioning aided by reconfigurable reflecting surfaces such as intelligent reflecting surfaces (IRS)

A method, apparatus, and computer program product provide for providing quality of service management during immersive content consumption. In the context of a method, the method includes receiving a first request comprising a positioning error set. The method also includes determining, based at least on the first request, an enhanced quality of service (QOS) indicator representing a QoS for a client device associated with the positioning error set. The method also includes causing transmission of a first response comprising configuration data related to a QoS flow for the client device, the configuration data being based at least on the enhanced QoS indicator.

Method, apparatus and computer program product providing quality of service management for extended reality applications

A method, apparatus, and computer program product are disclosed for modifying the transmission of media content update packets based on a determination that the elapsed uplink time and remaining downlink time in the aggregate are within a satisfactory round-trip delay time. In this regard, the method, apparatus, and computer program product are configured to correlate a returned media content update packet with an associated device update packet or packets. Correlating media content update packets with an associated device update packet may require identifying a returned packet containing a media content update by analyzing packets containing video streams to identify packets comprising reference video frames. Identifying reference video frame packets may assist in identifying the associated uplink packet or packets containing device pose and position or other user input.

Two-way delay budget for interactive services

Disclosed is a method comprising obtaining a reliability estimate indicating transmission success probability for a plurality of transmission legs and assigning a data packet type to a subset of the plurality of transmission legs based at least partly on said reliability estimate.

Leg selection for improved reliability of multi-connectivity

Methods and apparatuses for enhancement of quality of service flows, for extended reality services or other services are proposed. For example, a method can include receiving a plurality of quality of service parameters for first packet-based communication. The quality of service parameters can include a packet delay budget for the first packet-based communication having a first end time. The plurality of quality of service parameters can further include a packet validity time for the first packet-based communication having a second end time equal to or later than the first end time. The packet validity time can be applicable to the first packet-based communication on a protocol data unit session basis, a quality of service flow basis, a set of protocol data units basis, or a packet basis. The method can also include transmitting the packet of the first packet-based communication to a further communication device.

Packet validity time enhancement for quality of service flows

Disclosed are two methods, the first method comprising receiving a plurality of data packets, producing a coded data packet by coding together at least two data packets, wherein at least one of the at least two data packets is comprised in the received plurality of data packets or in a coding buffer, transmitting the at least two data packets to a first subset of legs, transmitting the coded data packets to a second subset of legs, and determining if the at least two data packets are to be duplicated based on, at least partly, one or more of the following: a notification, a condition, or a first indication. The second disclosed method comprises receiving a data packet and an indication of a coding function and parameters used for coding two or more data packets, determining if the received data packet is a coded data packet and if it is, determine if one or more internal buffers comprise a minimum set of data packets for generating the coded data packet, using sequence numbers assigned to each data packet, and if the one or more internal buffers comprise the minimum set of data packets, retrieve the minimum set of data packets from the one or more internal buffers, and decoding the coded data packet using the minimum set of data packets and the coding function and parameters indicated by the indication received.

Reliability of multi-connectivity

The present disclosure relates generally to the field of wireless communications, and in particular to techniques for efficiently transferring, among network nodes, an access context required to initiate data transfer when a user equipment (UE) is in an active or suspended Radio Access Network (RAN) connection state. The techniques disclosed herein involve identifying, based on UE-specific data (such, for example, as mobility information, a traffic profile), one or more relevant network nodes where the UE in the suspended RAN connection state could be located at the time when next data transfer needs to be initiated. After that, the access context is sent from an anchor network node to said one or more relevant network nodes. By sending the access context in this manner, network signalling overhead and storage capacity overhead may be significantly reduced.

Efficient transfer of access context for user equipment among network nodes

Techniques for determining a discontinuous reception configuration are disclosed. A user equipment may receive a discontinuous reception configuration from a network entity. The user equipment may select one or more discontinuous reception parameters to modify based at least in part on the received indication of a particular data burst class to be transmitted. The user equipment may receive a data burst and a selection command from the network entity. The user equipment selects one or more discontinuous reception parameters to modify based at least in part on the received indication of whether to apply the one or more adaptive parameters after the transmission of a current data burst is complete.

Method and apparatus for adaptive discontinous reception configuration

Systems, methods, apparatuses, and computer program products for real-time uplink (UL) power control are provided. One method may include estimating, by a network node, a power allocation function for determining power allocation across a plurality of legs that transmit simultaneously, the power allocation function being based on radio channel statistics and network performance metrics. The method may then include signaling, to a user equipment, the power allocation function and the parameters used to compute an output of the power allocation function.
