PUCCHformat 3 configuration parameters

expand all in page

    Description

    ThenrPUCCH3Configobject sets physical uplink control channel (PUCCH) configuration parameters for format 3, as defined in TS 38.211 Sections 6.3.2.1, 6.3.2.2, 6.3.2.6, and 6.4.1.3.3[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 defaultnrPUCCH3Configobject allocates a PUCCH format 3 in the first RB in the BWP and in all OFDM symbols in a slot.

    Creation

    Syntax

    pucch = nrPUCCH3Config
    pucch = nrPUCCH3Config(Name,Value)

    Description

    pucch= nrPUCCH3Configcreates a default PUCCH configuration object for format 3.

    Properties

    expand all

    Number of PRBs in the BWP, specified as[]or an integer from 1 to 275. To set this property to theNSizeGridproperty of thenrCarrierConfigobject, use[].

    Data Types:double

    Starting PRB index of the BWP relative to the common resource block 0 (CRB 0), specified as[]or an integer from 0 to 2473. To set this property to theNStartGridproperty of thenrCarrierConfigobject, use[].

    Data Types:double

    Modulation scheme, specified as'QPSK'or'pi/2-BPSK'.

    Modulation Scheme Number of Bits Per Symbol
    'pi/2-BPSK' 1
    'QPSK' 2

    Data Types:char|string

    OFDM symbol allocation of the PUCCH within a slot, specified as[]or a two-element vector of nonnegative integers. The first element of this property represents the start of symbol allocation. The second element represents the number of consecutively allocated OFDM symbols and must be in the range [4, 14]. To indicate that no OFDM symbols are allocated for the PUCCH, use[]or specify the second element of the vector as0.

    Data Types:double

    PRB (0-based) allocation of the PUCCH within the BWP, specified as a vector of integers from 0 to 274. To indicate that no resource blocks are allocated for the PUCCH, use[].

    Data Types:double

    Frequency hopping configuration for the PUCCH, specified as one of these values.

    • 'neither'— Indicates no frequency hopping

    • 'intraSlot'— Enables intraslot frequency hopping

    • 'interSlot'— Enables interslot frequency hopping

    When you enable interslot frequency hopping, the slot number determines the starting resource block for the allocated OFDM symbols. For even-numbered slots, the resource block starts from the minimum resource block allocated in thePRBSetproperty. For odd-numbered slots, the resource block starts from the resource block provided in theSecondHopStartPRBproperty.

    Data Types:char|string

    Starting PRB index of the second hop relative to the BWP, specified as an integer from 0 to 274.

    Data Types:double

    Group hopping configuration for the PUCCH, specified as one of these values.

    • 'neither'— Disables group hopping and sequence hopping

    • 'enable'— Enables group hopping and disables sequence hopping

    • 'disable'— Disables group hopping and enables sequence hopping

    This property is the higher-layer parameterpucch-GroupHopping.

    Data Types:char|string

    跳跃的身份PUCCH,指定为[]or an integer from 0 to 1023.

    • If the higher-layer parameterhoppingIdis configured, this property must be in the range from 0 to 1023.

    • If the higher-layer parameterhoppingIdis 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[], the object sets the PUCCH hopping identity to the physical layer cell identity specified by theNCellIDproperty of thenrCarrierConfigobject.

    Data Types:double

    PUCCHscrambling identity, specified as[]or an integer from 0 to 1023.

    • If the higher-layer parameterdataScramblingIdentityPUSCHis configured, this property must be in the range from 0 to 1023.

    • If the higher-layer parameterdataScramblingIdentityPUSCHis 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[], the object sets the PUCCH scrambling identity to the physical layer cell identity specified by theNCellIDproperty of thenrCarrierConfigobject.

    Data Types:double

    Radio network temporary identifier of the user equipment (UE), specified as an integer from 0 to 65,535.

    Data Types:double

    Option to enable additional demodulation reference signal (DM-RS), provided by the higher-layer parameteradditionalDMRS, specified as one of these numeric or logical values.

    • 0(false) — Disable additional DM-RS. When the number of the PUCCH OFDM symbols is greater than 9, two DM-RS symbols are present.

    • 1(true) — Enable additional DM-RS. When the number of the PUCCH OFDM symbols is greater than 9, four DM-RS symbols are present.

    Data Types:double|logical

    Create a default PUCCH configuration object for format 3.

    pucch = nrPUCCH3Config;

    Specify the number of PRBs in the BWP as 150, the modulation scheme as pi/2-BPSK, the PRB allocation of the PUCCH to range from 90 to 97, and the data scrambling identity as 650. Enable group hopping and the additional DM-RS configuration flag. Display the object properties.
