Abstract

Methods, systems, and devices for wireless communications are described. A network entity may transmit DCIs to a UE to schedule instances of one or more MBS TBs, the multiple instances of the one or more TBs being time-interleaved. For example, the network entity may transmit a first set of DCIs scheduling a first set of instances of a first TB, and a second set of DCIs scheduling a second set of instances of a second TB, where at least one instance of the first set of instances may be interleaved with the second set of instances. In some cases, the first and second set of DCIs may include one DCI to schedule the respective set of instances, or one DCI per instance of the respective set of instances. Additionally, or alternatively, the network entity may indicate one or more parameters to the UE associated with MBS inter-TB time interleaving.

Claims42

Dependent claims

A network entity for wireless communication, comprising:

a processing system configured to:
receive a first set of one or more downlink control information messages that collectively schedule a first set of instances of a first transport block;
receive a second set of one or more downlink control information messages that collectively schedule a second set of instances of a second transport block;
receive, via a set of one or more physical downlink shared channels (PDSCHs) in accordance with the first set of one or more downlink control information messages and the second set of one or more downlink control information messages, the first set of instances of the first transport block and the second set of instances of the second transport block for a multicast service or for a broadcast service, wherein at least one instance of the first set of instances of the first transport block is time-interleaved with the second set of instances of the second transport block;
and
decode the first transport block based on reception of the first set of instances of the first transport block.
