1. An apparatus of an access point (AP) multilink device (MLD), the apparatus-comprising one or more processors configured to perform operations comprising:
identifying a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD, wherein frames with identical data are associated with an identical first sequence number (SN) based on the first SNS;
identifying the first SN based on the first SNS; and
preparing, for transmission by the AP MLD to the non-AP MLD based on the first SN, a first frame that includes the data;
identifying a second SNS that is to be used by the AP MLD to transmit groupcast with retry block acknowledgment (GCR-BA) data;
identifying a second SN based on the second SNS; and
preparing, for transmission by the AP MLD to the non-AP MLD based on the second SN, a second frame that includes the GCR-BA data.
