Abstract: A wireless device receives radio resource control message(s) indicating: first uplink resources, of an uplink data channel, for a periodic resource allocation; a first offset parameter for uplink control information (UCI) transmission via the periodic resource allocation; and a plurality of second offset parameters for UCI transmission via a dynamic grant. A first UCI is transmitted via a number of the first uplink resources. The number of the first uplink resources is determined based on the first offset parameter. A downlink control information is received. The downlink control information comprises: an uplink grant indicating second uplink resources of the uplink data channel; and an offset indicator value indicating one of the plurality of second offset parameters. A second UCI is transmitted via a number of the second uplink resources. The number of the second uplink resources is determined based on the offset indicator value.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.
