Abstract: Various embodiments of the present disclosure provide a method for multicast communication. The method which may be performed by a terminal device comprises receiving a downlink control channel from a network node. The downlink control channel may be associated with a traffic of the terminal device. The method further comprises determining an uplink resource to transmit feedback for the traffic to the network node, according to the association between the downlink control channel and the traffic. According to various embodiments of the present disclosure, hybrid automatic repeat request feedback may be implemented efficiently and flexibly for different traffics such as multicast and unicast traffics.

Abstract: The application relates to a resource scheduling system (100) for a wireless communication network (102). The system comprises a first communication device (104a) and a second communication device (104b). The first and second communication devices (104a, 104b) belong to a group of plurality of communication devices (104, 104a, 104b) of the network. Each communication device (104, 104a, 104b) in the group of plurality of the communication devices is configured to provide a bi-directional radio communication with at least one of the plurality of the communication devices. The first communication device is configured to send a transmission resource configuration to rest (104, 104b) of the plurality of the communication devices. The first communication device is further configured to broadcast separately a transmission resource assignment to the rest of the plurality of the communication devices.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive a configuration message identifying a set of resources available for a plurality of UEs for transmission of feedback indications of multi-cast (or broadcast) transmission to the plurality of UEs, the set of resources comprising a plurality of subsets of resources, each subset of resources being associated with a corresponding channel metric for each UE of the plurality of UEs. The UE may determine that a feedback indication is to be provided in response to the multi-cast transmission. The UE may select, based at least in part on a channel metric of the UE, a first subset of the plurality of subsets of resources to use for transmitting a feedback message including the feedback indication. The UE may transmit the feedback message for the multi-cast transmission using resources within the selected first subset of resources.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for forward/retransmitting a data transmission to a target UE through a helper UE. A helper UE may receive a data transmission from a network node, determining whether the received data transmission is intended for a target UE or for the helper UE itself, based on a control message, and retransmitting the data transmission to the target UE upon determining that the data transmission is intended for the target UE. A network node such as a base station may transmit a control message to at least a help UE, the control message comprising an indicator of whether a data transmission is intended for the helper UE or a target UE and transmit the data transmission to at least the helper UE and the target UE.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications networks may implement aspects of a single frequency network (SFN), which may support multicast and broadcast transmissions. In some cases, a base station may use directional beamforming techniques to transmit a message to a user equipment (UE) using a first frequency configuration of the SFN. The base station may adjust the first frequency configuration to a second frequency configuration, and may transmit a retransmission of the message to the UE using the second frequency configuration.
