Power scaling and traffic-to-pilot power ratio signaling for shared demodulation reference signal

Abstract

Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to sharing a wideband demodulation reference signal (DMRS) among multiple physical downlink shared channel (PDSCH) communications, and to configuring the wideband DMRS to have a common energy per resource element (EPRE). Furthermore, in some aspects, the multiple PDSCH communications may have a common EPRE, such that a traffic-to-pilot power ratio (TPR) is the same for all PDSCH communications that share the wideband DMRS. Alternatively, a set of candidate TPR values may be configured and mapped to respective TPR codepoints, and scheduling information for each PDSCH communication may dynamically indicate a TPR codepoint associated with the respective PDSCH according to an EPRE associated with the respective PDSCH communication and the common EPRE associated with the wideband DMRS.
