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.

Abstract: Systems, methods, apparatuses, and computer program products for network-assisted signaling for uplink digital pre-distortion (DPD). A gNB may use an uplink reference signal (RS) to measure a user equipment's (UE's) power amplifier (PA) nonlinearity, where the UE may transmit its UE-specific RS with maximum transmit (Tx) power at a PA measurement window in the uplink. The gNB may train an artificial intelligence-based model to approximate the pre-distortion function (with PA parameters). The gNB may signal DPD-related information, and the UE may determine (and adjust) its DPD function based on the gNB signalling.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for enhancement of HARQ feedback. The method comprises: upon receipt of data of at least one of a group of services from a second device, generating, at a first device, a Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) codebook comprising HARQ feedback and identification information for the at least one service, the group of services comprising at least one of multicast and broadcast services (MBSs) and unicast services; and transmitting the HARQ-ACK codebook to the second device. In this way, retransmissions of unicast and multicast services can be accurately scheduled in time, and unnecessary retransmissions can be avoided. In addition, the spectral efficiency and packet loss rate of the communication system can be improved.
