Pdsch mapping type b

PDSCH or PUSCH Mapping Type A or B, used to determine PDSCH DM-RS symbol locations according to Section 7.4.1.1.2. If set to "Auto" this parameter is automatically configured based on propagated parameters from the upstream NR_DL_FRMASM. DMRS_CONFIGTYPE.

The UE expects the PDSCH mapping type indicated by DCI field ‘Time domain resource assignment‘ to be mapping type B, and the indicated PDSCH mapping type is applied to both PDSCH transmission occasions.

The reference PDSCH are not defined in slots which overlap the SS burst (slot 0 or slots 0 and 1). They use front loaded PDSCH mapping type A with 2 additional DM-RS positions. There is no FDM between the PDSCH and the DM-RS. The full-band PDSCH start at symbol 2 and the first 2 symbols in a slot contain a full occupied CORESET.

DM-RS Mapping Type B pour lequel le signal DM-RS est aligné temporellement avec le canal PDSCH. Le Type A permet au mobile de recevoir les informations de contrôle sur le premier symbole, puis le signal de référence DM-RS associé au canal PDSCH sur le symbole 2 ou le symbole 3, le slot étant entièrement utilisé pour transmettre des ...
Both PDSCH and PUSCH has two different types of mapping called Type A and Type B. These types are characterized by DMRS type (PDSCH DMRS type and PUSCH DMRS type) and SLIV table as shown below. < 38.214-Table 5.1.2.1-1: Valid S and L combinations >
3GPP Ver. 13, enhanced D2D ProSe, are based on Ver. 12. Two-hop relay communications is supported by D2D ProSe which is known as the UE-to-network relay. Reuse the PC5 interface in Ver. 12. Features of 3GPP Ver. 12 vs 3GPP Ver. 13. Three scenarios are supported by Ver. 12 and Ver. 13. In-coverage: All in-coverage UEs receive services from an eNB.
For example, mapping type B for PDSCH only supports duration 2, 4, and 7 in release 15, a restriction that has been lifted in release 16 to support any lengths from 2 to 13 in order to better support unlicensed spectra as discussed in Chapter 19, as well as to improve the support for dynamic spectrum sharing between NR and LTE on the same carrier.
Mapping is performed between bearers/RLC channels of the UE 206 and the IAB node 202 and between bearers/RLC channels of the IAB nodes 201, 202 and the IAB donor 200. The means to perform the mapping is specified by the adaptation layers of either the IAB donor 200 or the IAB nodes 201, 202. The data is routed through the bearers/RLC channels.
The Synchronisation Channel ( SCH) is a downlink signal used for cell search. The SCH consists of two sub channels, the Primary Synchronisation Channel ( Primary SCH) and Secondary Synchronisation Channel ( Secondary SCH ). The SCH is not transmitted during the first 256 chips of each slot, refer to P-CCPCH.
