1. A method of a User Equipment (UE), comprising:
receiving a configuration of a first Discontinuous Reception (DRX) timer with a value in number of symbols;
receiving a configuration of a second DRX timer with a value in number of slot lengths;
transmitting, via a Sidelink (SL) Hybrid Automatic Repeat Request (HARQ) process, a first SL transmission associated with SL configured grant Type 1;
starting the first DRX timer for the SL HARQ process in response to the first SL transmission, wherein the UE determines a first symbol length associated with the first DRX timer based on a symbol length of an active Downlink (DL) Bandwidth Part (BWP) of a Primary Cell (PCell);
starting the second DRX timer for the SL HARQ process in response to expiration of the first DRX timer which was started in response to the first SL transmission, wherein the UE determines a first slot length associated with the second DRX timer based on a slot length of the active DL BWP of the PCell; and
monitoring Physical Downlink Control Channel (PDCCH) when the second DRX timer is running.
