AdvancedReceiver-MU-MIMO (AdvancedReceiver-MU-MIMO-r18)
AdvancedReceiver-MU-MIMO-r18 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
The IE AdvancedReceiver-MU-MIMO is used to provide a set of assistance information for R-ML (reduced complexity ML) receivers with enhanced inter-user interference suppression for MU-MIMO transmissions.

}Fields (4)
| Field | Description |
|---|---|
| precodingAndResourceAllocation-r18 BOOLEAN · OPTIONAL Need M | If the field is set to true, the UE can assume the precoding and resource allocation of the co-scheduled UE are the same in the PRG-level grid configured to the target UE when PRG=2 or 4, when the target UE and any co-scheduled UEs are in different CDM groups and with the same DMRS sequence. If the field is set to false, the UE can not assume the precoding or resource allocation of the co-scheduled UE is the same in the PRG-level grid configured to the target UE when PRG=2 or 4, when the target UE and any co-scheduled UEs are in different CDM groups and with the same DMRS sequence. |
| pdsch-TimeDomainAllocation-r18 BOOLEAN · OPTIONAL Need M | If the field is set to true, the UE can assume the time domain resource assignment for PDSCH symbols of all the co-scheduled UE(s), which has the same DMRS sequence as the target UE, is same as the target UE. If the field is set to false, the UE can not assume the time domain resource assignment for PDSCH symbols of all the co-scheduled UE(s), which has the same DMRS sequence as the target UE, is same as the target UE. |
| mcs-Table-r18 ENUMERATED {qam1024, qam256, qam64, spare1} · OPTIONAL Need R | Indicates the MCS table with the highest modulation order among all MCS tables configured to the co-scheduled UE(s), which has the same DMRS sequence as the target UE. |
| advReceiver-MU-MIMO-DCI-1-1-r18 ENUMERATED {enabled} · OPTIONAL Need R | Configure the presence of the co-scheduled UE information field in DCI format 1_1 (see TS 38.212 [17], clause 7.3.1.2.2). |
