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.

Abstract: There is provided an apparatus including circuitry configured for performing: receiving radio transmission parameters for a set of base stations to transmit at least one data packet over same time-frequency physical resource blocks to the apparatus, the apparatus located in a first cell which is adjacent to a cell of at least one base station of the set of base stations; and receiving, in a data session, the at least one data packet at the apparatus; using the at least one data packet and the radio transmission parameters for interference cancellation for data signals received at the apparatus from user devices in the first cell.

Abstract: In accordance with some embodiments, a method may include receiving, by a first network entity, at least one user equipment context modification request from a second network entity. The method may further include configuring, by the first network entity, at least one of one or more unicast channels and one or more multicast channels. The method may further include receiving, by the first network entity, multicast data. The method may further include selecting, by the first network entity, at least one of one or more multicast channels and one or more unicast channels to transmit multicast data.

Abstract: According to an example aspect of the present invention, there is provided an apparatus including a memory configured to store received information, and at least one processing core configured to determine a quality level at which the received information was received, to select, based at least partly on the quality level, a feedback resource, and to decide on causing transmission of feedback on the selected feedback resource.
