Pilot Signal Allocation TRIZ Cases

Segments PRS resources by spatial filters to resolve the trade-off between positioning accuracy and measurement time.

A terminal transmits multiple transport blocks using distinct reference signals on pre-allocated grant-free uplink resources.

Segmenting estimation from filtering allows early parallel interference cancellation, reducing noise amplification and improving service data reliability.

Bundling demodulation reference signals across slots enhances random access message reception reliability while reducing latency in wireless networks.

A signal processing method segments data bits into sub-data signals and inserts pilot sequences at target positions to generate frequency-domain signals.

A communication system modulates non-edge subcarriers in downlink MU PPDUs to avoid transmitting data on frequency edges.

Terminals use preset resource sets to receive system information, reducing power consumption by excluding unnecessary resources.

High-layer signaling configures time-domain parameters for aperiodic sounding reference signal transmission, reducing PDCCH resource consumption.

Randomly selecting a PRACH occasion group from a mapped set improves uplink coverage while managing transmission delay during random access.

Optimizing DM-RS symbol placement via dynamic pattern selection improves channel estimation accuracy while managing resource overhead.

A base station selects non-overlapping physical uplink shared channel resources for user equipment to reduce interference in two-step random access.
