Abstract:
The apparatus is configured to transmit and/or receive GDMRS that may be scrambled based on a same scrambling identifier (ID) and shared for a plurality of UEs or channels. The apparatus, in some configurations, is further configured to multiplex, in time, data for the plurality of UEs or channels into different segments within each symbol in a set of symbols. The apparatus is further configured to transmit and/or receive the multiplexed data for the plurality of UEs or channels. In some configurations, the apparatus is further configured to demodulate the received data based on the GDMRS, and extract at least one segment for a UE or a plurality of channels associated with the apparatus within the demodulated data for subsequent decoding at the apparatus. In some configurations the extraction is based on a SLIV transmitted and/or received by the apparatus.
