Abstract

In an example, a User Equipment, UE, receives and/or detects a transmission of data from a network. The transmission of the data is addressed to a Group Radio Network Temporary Identifier, G-RNTI, for a Hybrid Automatic Repeat Request, HARQ, process (905). In response to receiving and/or detecting the transmission of the data, the UE (i) starts a first HARQ Round Trip Time, RTT, timer associated with the G-RNTI for the HARQ process, and (ii) starts a second HARQ RTT timer associated with a Cell Radio Network Temporary Identifier, C-RNTI, for the HARQ process (910). The UE starts a multicast retransmission timer for the HARQ process in response to expiry of the first HARQ RTT timer (915). The UE starts a unicast retransmission timer for the HARQ process in response to expiry of the second HARQ RTT timer (920). The UE receives and/or detects a first retransmission of the DL data addressed to the G-RNTI for the HARQ process (925). In response to receiving and/or detecting the first retransmission of the data, the UE (i) stops the multicast retransmission timer, and (ii) stops the unicast retransmission timer (930).
