In some aspects, the bit sequence in the single DCI message may be based on a PDCCH validation procedure used to validate scheduling activation and/or release where multiple Type 2 uplink CG configurations, multiple downlink SPS configurations, and/or the like are supported per bandwidth part. For example, a new field may be defined to indicate within the single DCI message the configuration(s) and/or configuration set(s) to be activated or released, and the new field may be padded in a Cell RNTI (C-RNTI) to adhere to the above-mentioned constraint to maintain the DCI size. Additionally, or alternatively, one or more existing DCI fields may be reinterpreted or repurposed to indicate the configuration(s) and/or configuration set(s) to be activated or released. For example, an existing DCI field that may be reinterpreted or repurposed may be a HARQ process number, which is a 4-bit field. In this way, by reinterpreting or repurposing an existing field, a need to pad a new field in the C-RNTI may be avoided. Furthermore, in cases where HARQ indices are divided among different CG and/or SPS configurations, the HARQ index that belongs to a CG and/or SPS configuration can be used to activate or release the corresponding configuration (e.g., the codepoint in the first technique described above may indicate the HARQ index that corresponds to a particular CG and/or SPS configuration). For example, the above-mentioned field for the HARQ process number has 4 bits because there can be up to 16 HARQ indices, and these HARQ indices can be divided among different CG and/or SPS configurations. For example, if the UE has four CG configurations, the 16 HARQ indices can be divided among the four CG configurations (e.g., 4 HARQ indices per CG configuration). Accordingly, in any of the first through third techniques, the bit sequence in the single DCI message may indicate one of the HARQ indices associated with a particular CG configuration, a particular SPS configuration, and/or the like to be activated or released. In other words, the HARQ indices can be used as proxies for the CG and/or SPS configurations to be activated or released.
