POWER SAVING TECHNIQUES FOR SIDELINK COMMUNICATION
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.

2 . A method for wireless communication at a first user equipment (UE), comprising:
selecting one or more sidelink discontinuous reception (DRX) parameters for a sidelink communication link, wherein the one or more sidelink DRX parameters are associated with one or more sidelink DRX timers; and
transmitting, from the first UE, the one or more sidelink DRX parameters associated with the one or more sidelink DRX timers to a second UE.
3 . The method of claim 2 , further comprising:
transmitting, to the second UE, at least one transmission on the sidelink communication link based on the one or more sidelink DRX parameters.
4 . The method of claim 2 , wherein the first UE is within a coverage area of a cell and the second UE is outside of the coverage area of the cell.
5 . The method of claim 2 , wherein the one or more sidelink DRX parameters are selected from a set of sidelink DRX parameters.
6 . An apparatus for wireless communication at a first user equipment (UE), comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
select one or more sidelink discontinuous reception (DRX) parameters for a sidelink communication link, wherein the one or more sidelink DRX parameters are associated with one or more sidelink DRX timers; and
transmit, from the first UE, the one or more sidelink DRX parameters associated with the one or more sidelink DRX timers to a second UE.
7 . The apparatus of claim 6 wherein the one or more processors are further configured to:
transmit, to the second UE, at least one transmission on the sidelink communication link based on the one or more sidelink DRX parameters.
8 . The apparatus of claim 6 , wherein the first UE is within a coverage area of a cell and the second UE is outside of the coverage area of the cell.
9 . The apparatus of claim 6 , wherein the one or more sidelink DRX parameters are selected from a set of sidelink DRX parameters.
10 . An apparatus for wireless communication at a first user equipment (UE), comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive, at the first UE, one or more sidelink discontinuous reception (DRX) parameters for a sidelink communication link from a second UE, wherein the one or more sidelink DRX parameters are associated with one or more sidelink DRX timers; and
receive, at the first UE, at least one transmission on the sidelink communication link based on the one or more sidelink DRX parameters associated with the one or more sidelink DRX timers from the second UE.
11 . The apparatus of claim 10 , wherein the one or more processors are further configured to:
monitor the sidelink communication link for the at least one transmission based on the one or more sidelink DRX parameters.
12 . The apparatus of claim 10 , wherein the first UE is outside of a coverage area of a cell and the second UE is within the coverage area of the cell.
13 . The apparatus of claim 10 , wherein the one or more sidelink DRX parameters are selected by the second UE from a set of sidelink DRX parameters.
