Abstract
Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive signaling indicating a set of multicast configurations for a set of multicast modes supported by the UE. Each multicast mode of the set of multicast modes may be associated with one or more radio resource control (RRC) states. The UE may determine a multicast configuration of the set of multicast configurations based on an RRC state according to which the UE is operating. The UE may receive, while operating according to the RRC state, multicast data according to the determined multicast configuration.
Claims30
A method for wireless communication at a user equipment (UE), comprising:
- receiving, from a network device, signaling indicating a plurality of multicast configurations for a plurality of multicast modes supported by the UE, each multicast mode of the plurality of multicast modes being associated with one or more radio resource control (RRC) states;
- and
- receiving, while operating according to an RRC state of the one or more RRC states and from the network device via a physical downlink shared channel, multicast data according to a multicast configuration of the plurality of multicast configurations, the multicast configuration being based at least in part on the RRC state.
A method for wireless communication at a network device, comprising:
- determining, for a user equipment (UE), a first multicast mode of a plurality of multicast modes supported by the network device, each multicast mode of the plurality of multicast modes associated with one or more radio resource control (RRC) states;
- transmitting signaling indicating a multicast configuration according to the first multicast mode;
- and
- transmitting, via a physical downlink shared channel, multicast data according to the transmitted multicast configuration.
An apparatus for wireless communication, comprising:
- a processor,
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive, from a network device, signaling indicating a plurality of multicast configurations for a plurality of multicast modes supported by the apparatus, each multicast mode of the plurality of multicast modes being associated with one or more radio resource control (RRC) states;
- and
- receiving, while operating according to an RRC state of the one or more RRC states and from the network device via a physical downlink shared channel, multicast data according to a multicast configuration of the plurality of multicast configurations, the multicast configuration being based at least in part on the RRC state.
An apparatus for wireless communication, comprising:
- a processor,
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- identify, for a user equipment (UE), a first multicast mode of a plurality of multicast modes supported by the apparatus, each multicast mode of the plurality of multicast modes associated with one or more radio resource control (RRC) states;
- transmit a multicast configuration according to the first multicast mode;
- and
- transmit, via a physical downlink shared channel, multicast data according to the transmitted multicast configuration.
