Abstract: Aspects relate to a control message that includes at least one symbol mask to be applied to a set of symbols of a time slot. In some examples, the control message may also include at least one resource element mask to be applied to at least one resource element of the time slot. In some aspects, information may be communicated during the time slot according to the at least one symbol mask.

Abstract: Certain aspects of the present disclosure provide techniques for power saving through discontinuous reception (DRX) in multiple subscriber identity module (multi-SIM) user equipment (UE). A method that may be performed by a UE includes determining a first DRX configuration associated with a first SIM and a second DRX configuration associated with a second SIM are asynchronous, generating, based on the first DRX configuration and the second DRX configuration, a synchronous DRX configuration for communicating with the first SIM and the second SIM, transmitting, to a first base station (BS) associated with the first SIM and to a second BS associated with the second SIM, an indication of the synchronous DRX configuration, and communicating with the first BS using the first SIM and the second BS using the second SIM in accordance with the synchronous DRX configuration.

Abstract: Certain aspects of the present disclosure provide techniques for dynamic configuration of demodulation reference signals (DMRSs). A method that may be performed by a base station (BS) includes receiving one or more uplink signals from at least one user equipment (UE); estimating a Doppler shift associated with the one or more uplink signals; determining a density of reference signals (RSs) within a slot for the at least one UE based, at least in part, on the estimated Doppler shift associated with the one or more uplink signals; and transmitting information to the at least one UE indicating an allocation of RS resources for the UE, wherein the allocation of the RS resources is based on the density of the RSs for the at least one UE.
