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: Embodiments of the present disclosure relate to methods, devices and computer readable storage medium for transport block size (TBS) configuration. In example embodiments, a terminal device transmits a random access preamble to a network device. The terminal device receives a random access response from the network device. The random access response includes a resource allocated for a reference TBS. Based on the reference TBS, the terminal device determines a TBS for transmitting data to the network device. Then, the terminal device transmits the data to the network device by using the determined TBS and the allocated resource. This TBS configuration is more flexible.

Abstract: Embodiments of the present disclosure relates to estimating downlink size for a multicast traffic. According to embodiments of the present disclosure, a first device receives downlink control information (DCI) for a multicast traffic. The first device determines field size(s) in the DCI based on one or more parameters which are associated with the field size estimation for the multicast traffic. The first device decodes the DCI based on the determined field sizes(s). In this way, the DCI can be blindly decoded correctly.

Abstract: Example embodiments of the present disclosure relate to polling a device for multicast broadcast service interest indication. A first device receives, from a second device, a physical downlink control channel (PDCCH) order addressed by a paging radio network temporary identifier for the first device. The PDCCH order comprises a request for an indication that at least one multicast broadcast service is to be received by the first device. The first device transmits, to the second device, a random access preamble associated with the at least one multicast broadcast service as a response to the request. Through this solution, the first device that monitors the single PDCCH order may have less power consumption.

Abstract: An apparatus including at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to identify at least one of a plurality of user equipment based on a pre-determined channel quality. A determination is made that point-to-point efficiency is greater than point-to-multipoint efficiency. At least one identified UE with worse channel condition is switched from point-to-multipoint to point-to-point.
