    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may convey uplink control information (UCI) to a base station using a multi-slot or single slot uplink channels. In some cases, however, transmissions scheduled on a first set of resources allocated for multi-slot transmission of a first uplink channel may overlap with one or more slots of a second set of resources allocated for multi-slot transmission of a second uplink control channel. Accordingly, the UE may employ a number of different techniques to transmit the UCI. In a first case, the UE may map the UCI to at least one of the overlapping slots of the first uplink channel. In a second case, the UE may drop the second uplink channel which carries the UCI. In a third case, and the UE may map the UCI to an overlapping slot of the second uplink channel.

    Abstract: Embodiments include systems and methods for supporting for supporting retransmission in a multicast session in a Fifth Generation (5G) New Radio (NR) (5G NR) radio access network (RAN). Various embodiments may provide an enhanced multicast radio bearer (MRB) architecture leveraging Packet Data Convergence Protocol (PDCP) status reporting by wireless devices to a base station of a 5G NR RAN. Various embodiments may support multiple Radio Link Control (RLC) entities, also referred to as RLC legs, in a multicast session. One or more multicast RLC legs may be used for multicast and/or unicast transmission to wireless devices and a unicast RLC leg may be used for unicast transmission to a specific wireless device. Various embodiments may enable PDCP level retransmission of PDCP protocol data units (PDUs).

    Abstract: Methods, systems, and devices for wireless communications are described. An encoding device (e.g., a base station or user equipment (UE)) may communicate, with a decoding device (e.g., a UE or base station), an indication of a set of encoding symbol identifiers via a control channel. The encoding device may transmit a set of packets associated with a rateless code via a data channel, where each of the set of packets includes an encoding symbol. The decoding device may decode the set of encoding symbols based on the set of encoding symbol identifiers.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, a broadcast message that indicates a plurality of occasions for a control resource set, wherein the plurality of occasions are associated with a plurality of component carriers that are associated with an unlicensed band; and monitor at least one of the plurality of occasions for the control resource set. In some aspects, a user equipment may receive, from a base station, a control message that indicates a plurality of occasions for at least one control resource set, wherein the plurality of occasions are associated with a plurality of component carriers that are associated with an unlicensed band; and monitor at least one of the plurality of occasions for the at least one control resource set. Numerous other aspects are provided.
