    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.

    Abstract: Embodiments of the present disclosure relate to frequency domain resource allocation for multicast traffic. A method comprises: receiving, at a first device and from a core network element, multicast traffic to be scheduled for a second device; generating assistance information for the second device, the assistance information enabling the second device to identify, within a bandwidth part configured for the second device, a frequency domain resource allocated for the multicast traffic; and transmitting the assistance GC information to the second device. The method further comprises: receiving, at the second device, the assistance information from a first device; and determining the frequency domain resource from downlink control information based on the assistance information. In this way, a significant flexibility to schedule multicast traffic can be provided, and a significant complexity reduction to a terminal device can be provided.

    Abstract: An example embodiment includes measuring by a user equipment, at least a signal quality and angle-of-arrival of wireless signals received from a network node; determining, by the user equipment, that the received wireless signals include signals from both primary path wireless beams and/or received reflected path wireless beams, based on the signal quality and the angle of arrival of the wireless signals; ranking, by the user equipment, the received wireless signals to primary path wireless beams and/or received reflected path wireless beams, based on the signal quality; and transmitting, by the user equipment, to the network node, at least one report including indications of both the received primary wireless beams having the best overall signal quality among both the primary and reflected beams, and received reflected path wireless beams having the best signal quality among the received reflected path wireless beams.

    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: Example embodiments of the present disclosure relate to configuration and interpretation of control information for a retransmission. A first device receives control information from a second device. In accordance with a determination that the control information indicates a retransmission to be scheduled from the second device. the first device determines an information combination of at least one of the following: at least one field of the control information, a search space in which the control information is received. and a format of the control information. The first device further determines a source traffic type of the retransmission based on the information combination, the source traffic type of the retransmission indicating whether the retransmission is for traffic in a point-to-multipoint initial transmission or in a point-to-point initial transmission.
