What is pusch in 5G?

In 5G NR, PUSCH is the physical uplink channel that carries user data. DM-RS and PT-RS are the reference signals associated with PUSCH. DM-RS is used for channel estimation as part of coherent demodulation of PUSCH. To compensate for the common phase error (CPE), 3GPP 5G NR introduced PT-RS.

What is Dmrs Type A?

Type A means it is on symbol 2 or 3 if DMRS is single symbol, in frequency domain it is on alternating subcarriers if it is type 1, it is separated by 6 SCs with DMRS on 2 consecutive SCs if it is type 2.

What is Pdsch in 5G NR?

Introduction. In 5G NR, PDSCH is the physical downlink channel that carries user data. DM-RS and PT-RS are the reference signals associated with PDSCH. These signals are generated within the PDSCH allocation, as defined in TS 38.211 Sections 7.4.

What is Dmrs in LTE?

PUSCHPhysical Uplink Shared Channel DMRS is the uplink user's shared channel Demodulation Reference Signal (DMRS) and is transmitted in each resource block allocated to the user. PUSCH DMRS is transmitted during symbol 3 (normal CP1) Contention period, or 2) Cyclic prefix) or symbol 2 (extended CP).
