SCHEMES FOR RECOVERY OF eMBB's RS PUNCTURING FROM DYNAMIC MULTIPLEXING OF URLLC/eMBB

摘要

Various aspects are described for schemes that address the potential puncturing of important reference signals (RSs) for enhanced mobile broadband (eMBB) applications, such as demodulation reference signal (DMRS), channel state information reference signal (CSIRS), tracking reference signal, and general reference signal. The schemes can be used for recovery of eMBB's RS puncturing from dynamic multiplexing of ultra-reliable-low-latency communications (URLLC) and eMBB. The schemes include a block-based scheme and an over-provisioning scheme. The schemes modify an existing RS pattern before puncturing occurs in response to a presence of the URLLC traffic. In addition, there can be an option not to use (e.g., disable) time-domain orthogonal cover code (TD-OCC) for the RSs.
