Reliable Transmission of Multicast and Broadcast Services

A wireless device receives parameters comprising a radio network temporary identifier (RNTI) associated with a multicast and broadcast service (MBS) session; a first scrambling identity associated with the MBS session; and a second scrambling identity associated with unicast transmissions. The wireless device receives, based on the RNTI, a group common downlink control information (DCI) scheduling a transport block (TB) of the MBS session. Based on the group common DCI being received based on the RNTI, the wireless device determines a scrambling identity for the TB being equal to the first scrambling identity, and receives the TB being scrambled with a scrambling sequence initialized by the determined scrambling identity and the RNTI.

POWER SAVINGS FOR VOICE SERVICES

Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).
