4.1 Power allocation for downlink
The gNB determines the downlink transmit EPRE.

For the purpose of SS-RSRP, SS-RSRQ and SS-SINR measurements, the UE may assume downlink EPRE is constant

across the bandwidth. For the purpose of SS-RSRP, SS-RSRQ and SS-SINR measurements, the UE may assume

downlink EPRE is constant over SSS carried in different SS/PBCH blocks. For the purpose of SS-RSRP, SS-RSRQ and

SS-SINR measurements, the UE may assume that the ratio of SSS EPRE to PBCH DM-RS EPRE is 0 dB.

For the purpose of CSI-RSRP, CSI-RSRQ and CSI-SINR measurements, the UE may assume downlink EPRE of a port

of CSI-RS resource configuration is constant across the configured downlink bandwidth and constant across all

configured OFDM symbols.

The downlink SS/PBCH SSS EPRE can be derived from the SS/PBCH downlink transmit power given by the parameter

ss-PBCH-BlockPower provided by higher layers. The downlink SSS transmit power is defined as the linear average

over the power contributions (in [W]) of all resource elements that carry the SSS within the operating system

bandwidth.

The downlink CSI-RS EPRE can be derived from the SS/PBCH block downlink transmit power given by the parameter

ss-PBCH-BlockPower and CSI-RS power offset given by the parameter powerControlOffsetSS provided by higher

layers. The downlink reference-signal transmit power is defined as the linear average over the power contributions (in

[W]) of the resource elements that carry the configured CSI-RS within the operating system bandwidth.

For downlink DM-RS associated with PDSCH, the UE may assume the ratio of PDSCH EPRE to DM-RS EPRE (

[dB]) is given by Table 4.1-1 according to the number of DM-RS CDM groups without data as described in

DMRS
DMRS

Subclause 5.1.6.2. The DM-RS scaling factor β specified in Subclause 7.4.1.1.2 of [4, TS 38.211] is given by

3 - -4.77 dB
When the UE is scheduled with a PT-RS port associated with the PDSCH,

- if the UE is configured with the higher layer parameter epre-Ratio, the ratio of PT-RS EPRE to PDSCH EPRE

per layer per RE for PT-RS port ( ρ ) is given by Table 4.1-2 according to the epre-Ratio, the PT-RS scaling

PTRS

factor β specified in subclause 7.4.1.2.2 of [4, TS 38.211] is given by β = 10 .

For link recovery, as described in clause 6 of [6, TS 38.213] the ratio of the PDCCH EPRE to NZP CSI-RS EPRE is

assumed as 0 dB.
5 Physical downlink shared channel related procedures
5.1 UE procedure for receiving the physical downlink shared
channel

For downlink, a maximum of 16 HARQ processes per cell is supported by the UE. The number of processes the UE

may assume will at most be used for the downlink is configured to the UE for each cell separately by higher layer

parameter nrofHARQ-ProcessesForPDSCH, and when no configuration is provided the UE may assume a default

number of 8 processes.

A UE shall upon detection of a PDCCH with a configured DCI format 1_0 or 1_1 decode the corresponding PDSCHs

as indicated by that DCI. For any HARQ process ID(s) in a given scheduled cell, the UE is not expected to receive a

PDSCH that overlaps in time with another PDSCH. The UE is not expected to receive another PDSCH for a given

HARQ process until after the end of the expected transmission of HARQ-ACK for that HARQ process, where the

timing is given by Subclause 9.2.3 of [6]. In a given scheduled cell, the UE is not expected to receive a first PDSCH in

slot i, with the corresponding HARQ-ACK assigned to be transmitted in slot j, and a second PDSCH starting later than

the first PDSCH with its corresponding HARQ-ACK assigned to be transmitted in a slot before slot j. For any two

HARQ process IDs in a given scheduled cell, if the UE is scheduled to start receiving a first PDSCH starting in symbol

j by a PDCCH ending in symbol i, the UE is not expected to be scheduled to receive a PDSCH starting earlier than the

end of the first PDSCH with a PDCCH that ends later than symbol i. In a given scheduled cell, for any PDSCH

corresponding to SI-RNTI, the UE is not expected to decode a re-transmission of an earlier PDSCH with a starting

symbol less than N symbols after the last
