DEMODULATION REFERENCE SIGNAL RESOURCE ALLOCATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18183343 Titled 'DEMODULATION REFERENCE SIGNAL RESOURCE ALLOCATION'
Simplified Explanation
The abstract describes a wireless communication system where a user equipment (UE) can transmit information to a network entity regarding the number of demodulation reference signal (DMRS) ports for DMRS communications. The UE can then receive information from the network entity that restricts resource allocation for a physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) to a multiple of two for each contiguous physical resource block. It can also restrict the mapping of virtual resource blocks to physical resource blocks (VRB-to-PRB mapping) and limit the number of orthogonal DMRS ports to avoid multiplexing legacy and extended DMRS ports in the same code division multiplexing (CDM) group. The abstract mentions that there are numerous other aspects described in the disclosure.
Original Abstract Submitted
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, demodulation reference signal (DMRS) capability information that indicates a number of orthogonal DMRS ports for DMRS communications. The UE may receive, from the network entity, information that is associated with a DMRS port mapping for the number of orthogonal DMRS ports and that indicates to restrict a resource allocation for a physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) to an integer that is a multiple of two for each contiguous physical resource block, to restrict a virtual resource block to physical resource block (VRB-to-PRB) mapping, or to restrict the number of orthogonal DMRS ports such that a legacy number of DMRS ports and an extended number of DMRS ports are not multiplexed in a same code division multiplexing (CDM) group. Numerous other aspects are described.
