Abstract
Certain aspects provide a method for wireless communication by a first user-equipment (UE). The method generally includes applying a discontinuous reception (DRX) configuration for the first UE, monitoring for first signaling from a second UE indicating that the second UE has data to send to the first UE, the first signaling being transmitted using a plurality of transmit beams during a DRX cycle of the DRX configuration, selecting one or more transmit beams of the plurality of transmit beams based on the monitoring of the first signaling, and communicating in accordance with the selection.

A method for wireless communication by a first user-equipment (UE), comprising:
- applying a discontinuous reception (DRX) configuration for the first UE;
- monitoring for first signaling from a second UE indicating that the second UE has data to send to the first UE, the first signaling being transmitted using a plurality of transmit beams during a DRX cycle of the DRX configuration;
- selecting one or more transmit beams of the plurality of transmit beams based on the monitoring of the first signaling;
- and
- communicating in accordance with the selection, wherein:
- the first signaling is transmitted by the second UE and a third UE;
- the first signaling transmitted from the second UE comprises a sequence indicating an identifier (ID) associated with the first UE and the second UE;
- and
- the first signaling transmitted from the third UE comprises a sequence indicating an ID associated with the first UE and the third UE.
A method for wireless communication by a first user-equipment (UE), comprising:
- transmitting first signaling to a second UE if the first UE has data to send to the second UE, the first signaling being transmitted using a plurality of transmit beams during a DRX cycle of a DRX configuration of the second UE;
- receiving an indication of one or more transmit beams of the plurality of transmit beams;
- and
- communicating in accordance with the received indication, wherein:
- the first signaling is transmitted to the second UE and a third UE;
- the first signaling transmitted to the second UE comprises a sequence indicating an identifier (ID) associated with the first UE and the second UE;
- and
- the first signaling transmitted to the third UE comprises a sequence indicating an ID associated with the first UE and the third UE.
An apparatus for wireless communication by a first user-equipment (UE), comprising:
- a memory;
- and
- one or more processors coupled to the memory, the memory and the one or more processors being configured to:
- apply a discontinuous reception (DRX) configuration for the first UE;
- monitor for first signaling from a second UE indicating that the second UE has data to send to the first UE, the first signaling being transmitted using a plurality of transmit beams during a DRX cycle of the DRX configuration;
- select one or more transmit beams of the plurality of transmit beams based on the monitoring of the first signaling;
- and
- communicate in accordance with the selection, wherein:
- the first signaling is transmitted by the second UE and a third UE;
- the first signaling transmitted from the second UE comprises a sequence indicating an identifier (ID) associated with the first UE and the second UE;
- and
- the first signaling transmitted from the third UE comprises a sequence indicating an ID associated with the first UE and the third UE.
An apparatus for wireless communication by a first user-equipment (UE), comprising:
- a memory;
