nrPUCCH1Config
Description
The nrPUCCH1Config
object sets physical uplink control channel
(PUCCH) configuration parameters for format 1, as defined in TS 38.211 Sections 6.3.2.1,
6.3.2.2, 6.3.2.4, and 6.4.1.3.1 [1]. The object also configures
the bandwidth part (BWP) containing the PUCCH and the number of resource blocks (RBs) that the
PUCCH occupies within the BWP.
The default nrPUCCH1Config
object allocates a PUCCH format 1 in the first
RB in the BWP and in all OFDM symbols in a slot.
For operation with shared spectrum channel access
for frequency range 1 (FR1), set the Interlacing
property to true
, then use the
RBSetIndex
and InterlaceIndex
object properties to specify the allocated frequency
resources. (since R2023b)
Creation

PUCCH configuration object for format 1.pucch
= nrPUCCH1Config
specifies properties using one
or more name-value pairs. Enclose each property in quotes. For example,
pucch
= nrPUCCH1Config(Name,Value
)'NSizeBWP',200
specifies 200 physical resource blocks (PRB) in the
BWP.

(false
).
Data Types: double
FrequencyHopping

block starts from the minimum resource block allocated in the
PRBSet

starts from the resource block provided in the SecondHopStartPRB

property to
'intraSlot'
or 'interSlot'
and set the
Interlacing
property to 0
(false
).
Data Types: double
Interlacing

0
or false
(default) | 1
or true
Since R2023b
Interlaced resource allocation, specified as one of these values.
0
(false
) — Disable interlaced resource allocation.1
(true
) — Enable interlaced resource allocation. Use theRBSetIndex
andInterlaceIndex
properties to configure the frequency resource allocation.
This property implements the useInterlacePUCCH-PUSCH higher-layer parameter.
Data Types: double
| logical
RBSetIndex
— Indices of RB sets between intracell guard bands
0
(default) | vector of nonnegative integers
Since R2023b
Indices of RB sets between intracell guard bands (0-based), specified as a vector of nonnegative integers. Use this property to specify the indices of the RB sets in an interlaced resource allocation.
Dependencies
To enable this property, set the Interlacing
property to
1
(true
).
Data Types: double

Since R2023b
Interlace indices in the interlaced resource allocation, specified as a vector of nonnegative integers with up to M elements. The vector element must be in the range [0, M – 1). M = 10 for 15 kHz subcarrier spacing and M = 5 for 30 kHz subcarrier spacing.
Dependencies
To enable this property, set the
Interlacing

GroupHopping

If the higher-layer parameter hoppingId is not configured, this property must be equal to the physical layer cell identity and be in the range from 0 to 1007.
When you specify this property as []

hopping identity to the physical layer cell identity specified by the NCellID
property of the nrCarrierConfig
object.

Version History
Introduced in R2021aR2023b: Support for release 16 interlacing for operation in unlicensed spectrum (NR-U)
Use the Interlacing
, RBSetIndex
, and InterlaceIndex
properties to configure interlaced PUCCH
transmissions. Setting the Interlacing
property to
true
disables the PRBSet
and FrequencyHopping
properties.
R2023a: Release 17 updates to PRBSet
property
You can now set the PRBSet
object property to a vector, as defined in Release 17 of
TS 38.213 Section 9.2.1 and TS 38.211 Section 6.3.2.4. In previous releases, you set this
property to a scalar.
