Fields (4)
| Field | Description |
|---|---|
| pusch-DMRS-Bundling-r17 ENUMERATED {enabled} · OPTIONAL Need R | Indicates whether DMRS bundling and time domain window for PUSCH are jointly enabled. |
| pusch-TimeDomainWindowLength-r17 INTEGER (2..32) · OPTIONAL Need S | Configures the length of a nominal time domain window in number of consecutive slots for DMRS bundling for PUSCH. The value shall not exceed the maximum duration for DMRS bundling for PUSCH as specified in TS 38.306 [26]. For PUSCH repetition type A/B, if this field is absent, the UE shall apply the default value that is the minimum value in the unit of consecutive slots of the time duration for the transmission of all PUSCH repetitions and the maximum duration for DMRS bundling for PUSCH as specified in TS 38.306 [26]. For TBoMS, if this field is absent, the UE shall apply the default value that is the minimum value in the unit of consecutive slots of the duration of TBoMS transmission (including repetition of TBoMS) and the maximum duration for DMRS bundling for PUSCH as specified in TS 38.306 [26]. |
| pusch-WindowRestart-r17 ENUMERATED {enabled} · OPTIONAL Need R | Indicates whether UE bundles PUSCH DMRS remaining in a nominal time domain window after event(s) triggered by DCI or MAC CE that violate power consistency and phase continuity requirements is enabled (see TS 38.214 [19], clause 6.1.7). NOTE: Events, which are triggered by DCI or MAC CE, but do not require UE capability to resume maintaining power consistency and/or phase continuity as specified in clause 6.1.7 of TS 38.214 [19], are excluded. |
| pusch-FrequencyHoppingInterval-r17 ENUMERATED {s2, s4, s5, s6, s8, s10, s12, s14, s16, s20} · OPTIONAL Need S | Configures the number of consecutive slots for the UE to perform inter-slot frequency hopping with inter-slot bundling for PUSCH. When both inter-frequency hopping and DMRS bundling are enabled for PUSCH repetitions, the UE is expected to be configured with at least one pusch-FrequencyHoppingInterval-r17 and pusch-TimeDomainWindowLength-r17 . This parameter is shared for both DG-PUSCH and CG-PUSCH. When DMRS bundling for PUSCH is enabled by pusch-DMRS-Bundling-r17, PUSCH frequency hopping interval is only determined by the configuration of PUSCH hopping interval if PUSCH hopping interval is configured. If the field is absent, the number of consecutive slots for the UE to perform inter-slot PUSCH frequency hopping is indicated by pusch-TimeDomainWindowLength-r17. Note: For unpaired spectrum, the UE is not expected to be configured the value of s6, s8, s12, s14 and s16. |
