Abstract: Disclosed are methods for power control on negative acknowledgement transmission. An example method may include receiving at a terminal device from a network device, at least one parameter relating to a transmit power for transmission of a negative acknowledgement from the terminal device to the network device on a hybrid automatic repeat request process, wherein the negative acknowledgement may indicate a request for a retransmission of a packet sent from the network device to the terminal device on the hybrid automatic repeat request process, determining at least one missed negative acknowledgement, wherein the at least one missed negative acknowledgement may include at least one sent negative acknowledgement for which no corresponding retransmission from the network device has been received at the terminal device on the hybrid automatic repeat request process, calculating a negative acknowledgement miss rate based at least on the determination of the at least one missed negative acknowledgement, and adjusting the transmit power for the transmission of the negative acknowledgement based at least on the calculated negative acknowledgement miss rate and the at least one parameter. Related apparatuses and computer readable media are also disclosed.

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: A method, apparatus, and a computer-readable storage medium are provided for joint encoding of downlink control information (DCI) fields to support hybrid automatic request-acknowledgement (HARQ-ACK) delays for more than 10 HARQ processes (e.g., 14 HARQ processes) at a user equipment. In an example implementation, the method may include a user equipment (UE) determining a number of hybrid automatic repeat request (HARQ) processes configured at the UE and determining a HARQ acknowledgement (HARQ-ACK) delay value based at least on the number of HARQ processes configured at the UE and downlink control information (DCI) received from a network node.

Abstract: Disclosed are methods and apparatus for multiplexing NACK-only HARQ feedback. A terminal device in a communication network may comprise at least one processor and at least one memory having computer program code stored thereon. The at least one memory and the computer program code may be configured, with the at least one processor, cause the terminal device to perform: receiving, from a network device, one or more uplink control channel configurations for transmitting HARQ feedback for multicast transmission of one or more services; receiving, from the network device, the multicast transmissions of the one or more services; converting HARQ feedback bits of the HARQ feedback for the multicast transmissions of the one or more services; multiplexing the converted HARQ feedback bits into a multiplexed HARQ feedback; selecting a physical uplink control channel (PUCCH) resource for transmission of the multiplexed HARQ feedback; and transmitting the multiplexed HARQ feedback using the selected PUCCH resource.
