Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an initiator device may transmit a protocol data unit (PDU) associated with a first stream during a first subevent within a portion of an event that is shared between the first stream and a second stream. Additionally, or alternatively, the initiator device may transmit a PDU associated with the second stream during a second subevent within the portion of the event that is shared between the first stream and the second stream. Numerous other aspects are described.

14 . The apparatus of claim 1 , wherein the PDU associated with the second stream includes one or more bits in a header indicating that the PDU is for the second stream.
15 . The apparatus of claim 1 , wherein the PDU associated with the second stream is associated with a message integrity check (MIC) to indicate that the PDU is for the second stream.
16 . The apparatus of claim 1 , wherein the PDU associated with the second stream is associated with an inverted cyclic redundancy check (CRC) to indicate that the PDU is for the second stream.
17 . The apparatus of claim 1 , wherein the PDU associated with the second stream is associated with a time offset relative to the PDU associated with the first stream.
18 . An apparatus for wireless communication at an acceptor device, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
activate a low power mode during one or more first subevents within a portion of a single event that is shared between a first stream for the acceptor device and a second stream, wherein the portion of the single event includes the first subevent and one or more second subevents, and wherein the portion of the single event comprises one or more common subevents shared between the first stream and the second stream; and
