Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate generally to UE discontinuous reception (DRX) timing in association with a cell discontinuous transmission (DTX) configuration and/or a cell DRX configuration (“cell DTX/DRX configuration”).

Abstract: Methods, systems, and devices for joint sensing and data communication. A first sensing signal and a second sensing signal are transmitted in sequence, from a transmitter and using the same carrier frequency, for combined processing by a receiver. In some implementations, the sensing signals are radar signals. Data communication during an intervening time period between the first sensing signal and the second sensing signal involves the transmitter sending a data communication signal to another device or vice versa. Phase continuity between the first sensing signal and the second sensing signal can be maintained through performing radio frequency (RF) tuning on the transmitter after the transmitter transmits the data communication signal. The RF tuning may involve storing and restoring an operating state of a power amplifier in the transmitter. Alternatively, phase continuity can be maintained through preventing the transmitter from transmitting over an entirety of the intervening time period.

Additionally or alternatively, information related to a cell DTX configuration may be signaled in a system information block (SIB) or a multicast/broadcast service (MBS) configuration for UEs receiving MBS communications.
