Abstract: There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the second access node, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.

Abstract: There is provided a method, computer program, and for an apparatus for causing an apparatus for a user equipment to perform: receiving, a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, an indication of when the first timing advance value will be invalid; using the indication of when the first timing advance value will be invalid to determine that the first timing advance value is or will soon be invalid; and determining whether to autonomously initiate obtaining a second timing advance value for the target cell in dependence on the determination of whether the first timing advance value is or will soon be invalid, the second timing advance value being obtained later in time than the first timing advance value.

Abstract: This specification describes a terminal device comprising: means for establishing a radio communications link between the terminal device and a serving cell of a telecommunications network; means for executing a transfer of the radio communications link from the serving cell to a target cell of the telecommunications network; means for detecting that a timer, expiry of which causes declaration of a radio link failure with the serving cell, has reached a threshold value but has been stopped prior to expiry and prior to execution of the transfer; and means for, after successful execution of the transfer, controlling the transmission or the content of a transfer report based on the detecting.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enabling a successful Mobility Robustness Optimization analysis for primary secondary cell (PSCell) changes. The method comprises transmitting, from a terminal device to a master node of the terminal device, information related to a node initiating a successful PSCell change for the terminal device, wherein the information is indicative of at least one of the following: whether the node initiating the successful PSCell change is either a master node or a secondary node for the apparatus; a cell identifier of the node initiating the successful PSCell change.

Abstract: This disclosure presents methods and processes to allow a user equipment (UE) to map a hybrid automatic retransmission request-acknowledgement (HARQ-ACK) feedback to one or more HARQ-ACK sub-codebooks for received services. The one or more HARQ-ACK sub-codebooks can be concatenated into one HARQ-ACK codebook and then communicated to a communication node, when those services use a HARQ-ACK feedback that is scheduled for the same time instance. Various methods can be used for the concatenation order depending on the number of multicast and broadcast services (MBS) for which HARQ feedback is to be provided, and depending on whether HARQ-ACK feedback is to be sent for unicast services at the scheduled time instance. The concatenation order can utilize an increasing order or a decreasing order of the concatenation order parameters.

Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for channel state information (CSI) reporting. According to embodiments of the present disclosure, a first device receives from a second device a configuration for CSI reporting. The configuration comprises at least a block error rate target and an indication of a number of HARQ transmissions. The first device determines Channel Quality Indicator (CQI) based on the block error rate target and the number of HARQ transmissions indicated by the configuration and transmits a CSI report comprising the CQI to the second device. The solution enables CSI feedback that is suitable for spectrally efficient and reliable delivery of Point to Multipoint services while meeting the delay requirement, in particular in the context of NACK-only feedback on common feedback resources.
