- the network may define rules or conditions which indicate which TB is to be dropped/omitted in cases where the UE is to transmit a PUSCH message including only a subset of the configured TBs for a given PUSCH transmission occasion. Such rules/conditions may be used by the network to determine which TB to decode first. In other words, the network may be configured to decode “TB1"’ for a respective PUSCH message, but the rules/configurations may define which TB is regarded as “TB1.”
- uplink control information (UCI) messages multiplexed with transmitted PUSCH messages may include a bit field that indicates whether or not TB2 is included within the PUSCH message. As such, the network may determine whether or not to monitor for (and decode) TB2 based on the indicated bit field.

- the UE 115 may transmit PUSCH messages 230 within the allocated resources (e.g., within the PUSCH transmission occasions 215) if the UE 115 has uplink data in a message buffer.
- Such CG-PUSCH configurations may be usable in cases where the uplink data at the UE 115 has a variable instantaneous data generation rate.
- Some wireless communications systems may support different types of CG- PUSCH configurations, such as CG-PUSCH Type 1 and CG-PUSCH Type 2.
- CG-PUSCH Type 1 all the information of the CG-PUSCH is configured and activated via RRC signaling. That is, the UE 115-a may receive a Type 1 CG-PUSCH configuration via RRC signaling, where the RRC signaling also activates the CG- PUSCH configuration.

Stated differently, the UE 115 -a may autonomously determine/signal parameters for each respective PUSCH transmission occasion 215, such as the HARQ ID, the NDI. and RV. Such parameters may be indicated via UCI messages 235 associated with (e.g.. communicated within) the respective PUSCH transmission occasions 215. The NDI may be toggled for a respective PUSCH transmission occasion 215 to indicate that the PUSCH transmission occasion 215 is used for a new transmission, otherwise, it is used for a retransmission (or vice versa).

- the CG-UCI (e.g., UCI message 235) may be encoded separately and multiplexed on the CG-PUSCH message 230 that the information corresponds to (e.g., UCI message 235 multiplexed with a PUSCH message 230 of the first PUSCH transmission occasion 215-a indicates information associated with the PUSCH message 230/first PUSCH transmission occasion 215-a).
- the network entity 105-a may decode the CG-UCI (UCI message 235), and use the information of the CG-UCI to decode the uplink data of the PUSCH message 230.
- Table 1 illustrates information that may be communicated within UCI messages 235 associated with CG-PUSCH configurations:
- PUSCH transmission occasions 215 of a CG-PUSCH configuration may support a single TB 240 or CW. That is, for each PUSCH transmission occasion 215, the UE 115-a may transmit a PUSCH messages 230 including a single TB 240.
- PUSCH transmission occasions 215 may be associated with multiple TBs 240 or CWs.

- the UE 115-a may PUSCH messages 230 in each PUSCH transmission occasion 215 that include the first TB 240-a (TB1) and the second TB 240-b (TB2).
- a message buffer at the UE 115-a may not include uplink data to be transmitted, or may include only a small amount of data to be transmitted. In such cases, the UE 115-a may not need to use two TBs 240 for each PUSCH transmission occasion 215 to transmit all the buffered data.
- some networks use binary rules or configurations in which each PUSCH transmission occasion 215 is completely used (e.g., first TB 240-a and second TB 240-b are both transmitted in each PUSCH transmission occasion 215), or where each PUSCH transmission occasion 215 is completely skipped (e.g., first TB 240-a and second TB 240-b are both skipped). Such binary rules offer little flexibility.
- the UE 115-a may nonetheless be expected to skip transmitting both TBs 240, thereby resulting in increased latency associated with the data that could have otherwise be communicated via the first TB 240-a.
- the UE 115-a and the network entity 105-a of the wireless communications system 200 may support configurations and mechanisms that enable the UE 115-a to drop subsets of TBs 240 from PUSCH messages 230 communicated in PUSCH transmission occasions 215 configured for multiple TBs 240.

- the control signaling 210 may indicate that the PUSCH transmission occasions 215 are enabled for transmission of two TBs 240 each (e g., first TB 240-a and second TB 240-b). While much of the present disclosure is described in the context of PUSCH transmission occasions 215 that are enabled for a maximum of two TBs 240 per PUSCH transmission occasion 215 (e.g., TB 1 and TB2), this is solely for illustrative purposes.

Subsequently, the uplink buffer at the UE 115-a may include a smaller amount of uplink data to be transmitted.

That is, the UE 115-b may omit (e.g., skip) one or more TBs 240 from PUSCH messages 230 transmitted via the PUSCH transmission occasions 215-b and 215-e.
- the maximum quantity of enabled TBs 240 e.g. PUSCH transmission occasions 215-a, 215-c. 215-d

- each of the TBs 305 mapped to the respective sets of MIMO layers 310 may be precoded for the PUSCH message at 315 (thereby generating CWs after encoding), and may go through waveform generation at 320 to generate a waveform/PUSCH message that includes both TBs 305.
- the UE 115 may be configured to include/transmit the first TB 305-a, and omit or skip the second TB 305-b. For instance, as shown in FIG. 3, the UE 115 may perform precoding of the first TB 305-a at 315, and may perform waveform generation at 320 to generate a waveform/PUSCH message that includes only the first TB 305-a.

In other words, such bit field values may prevent the need for the network entity’ 105-a to perform blind detection to determine whether TBs 240 are skipped in the respective PUSCH messages 230 or not.
