    Abstract: Aspects of the disclosure relate to efficiently exchanging data in power-limited wideband communications. A base station and a UE transmit data using sub-band position modulation (SBPM), in which a select subset of frequency sub-bands carry the data transmission. At a given interval of the streamed data portion, a new subset of the sub-bands may be selected as the active sub-bands, thus modulating the active sub-band positions during the data transmission. A receiver monitors for the data transmission signal and detects the sub-bands on/off state in order to receive the data within the active sub-bands. The entities exchange no control information indicating which sub-bands a given transmission uses. Further, SBPM includes pattern recognition by both devices in order to convey additional information each interval by selecting the positions of the active sub-bands to match the pattern associated with the information to be conveyed.

    Abstract: Certain aspects of the present disclosure provide techniques for communicating using power control parameters for multiple transmitter receiver point (mTRP) physical uplink shared channel (PUSCH) repetition. A method that may be performed by a user equipment (UE) includes receiving a sounding reference signal (SRS) configuration indicating at least a first SRS resource set and at least a second SRS resource set, receiving downlink control information (DCI) scheduling a first set of one or more PUSCH repetitions to a first TRP and a second set of one or more PUSCH repetitions to a second TRP, and transmitting the first and second sets of PUSCH repetitions using at least one of a first set of default power control parameters or a second set of default power control parameters.
