Definition

The IE SchedulingRequestResourceConfig determines physical layer resources on PUCCH where the UE may send the dedicated scheduling request (D-SR) (see TS 38.213 [13], clause 9.2.4).

SchedulingRequestResourceConfig ::=     SEQUENCE {

FieldDescription
schedulingRequestResourceId
SchedulingRequestResourceId
schedulingRequestID
SchedulingRequestId
The ID of the SchedulingRequestConfig that uses this scheduling request resource.
periodicityAndOffset
CHOICE { · OPTIONAL Need M
SR periodicity and offset in number of symbols or slots (see TS 38.213 [13], clause 9.2.4) The following periodicities may be configured depending on the chosen subcarrier spacing: SCS = 15 kHz: 2sym, 7sym, 1sl, 2sl, 4sl, 5sl, 8sl, 10sl, 16sl, 20sl, 40sl, 80sl SCS = 30 kHz: 2sym, 7sym, 1sl, 2sl, 4sl, 5sl, 8sl, 10sl, 16sl, 20sl, 40sl, 80sl, 160sl SCS = 60 kHz: 2sym, 7sym/6sym, 1sl, 2sl, 4sl, 8sl, 16sl, 20sl, 40sl, 80sl, 160sl, 320sl SCS = 120 kHz: 2sym, 7sym, 1sl, 2sl, 4sl, 5sl, 8sl, 10sl, 16sl, 40sl, 80sl, 160sl, 320sl, 640sl SCS = 480 kHz: 1sl, 2sl, 4sl, 8sl, 16sl, 40sl, 80sl, 160sl, 320sl, 640sl, 1280sl, 2560sl SCS = 960 kHz: 1sl, 2sl, 4sl, 8sl, 16sl, 40sl, 80sl, 160sl, 320sl, 640sl, 1280sl, 2560sl, 5120sl sym6or7 corresponds to 6 symbols if extended cyclic prefix and a SCS of 60 kHz are configured, otherwise it corresponds to 7 symbols. For periodicities 2sym, 7sym and sl1 the UE assumes an offset of 0 slots. If periodicityAndOffset-r17 is present, any previously configured periodicityAndOffset (without suffix) is released, and vice versa. UE indicates support of the following SR periodicities in additionalSR-Periodicities (see TS 38.306, clause 4.2.6): SCS = 30 kHz: 5sl SCS = 120 kHz: 5sl, 10sl

resource
PUCCH-ResourceId · OPTIONAL Need M
ID of the PUCCH resource in which the UE shall send the scheduling request. The actual PUCCH-Resource is configured in PUCCH-Config of the same UL BWP and serving cell as this SchedulingRequestResourceConfig . The network configures a PUCCH-Resource of PUCCH-format0 or PUCCH-format1 (other formats not supported) (see TS 38.213 [13], clause 9.2.4). If this field is included in a ltm-SchedulingRequestResourceConfig IE within ltm-SchedulingRequestInfo , this field refers to the PUCCH resources to be used within the first active UL BWP.
