Abstract: Methods, systems, and devices for wireless communications are described. A base station of a first network operator (OP) may determine a priority for the first OP for a transmission opportunity of a shared or unlicensed channel. The priority may be lower than a priority of a second OP for the transmission opportunity. Base station may transmit a tentative grant to a user equipment (UE) of the first OP scheduling transmissions over resources of the transmission opportunity. The transmitting device of the first OP may monitor a contention window for reservation signals communicated by devices of the second OP. Based on the monitoring and the tentative grant, the transmitting device of the first OP may perform the transmission over the resources of the shared or unlicensed channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a first transmission of a first service type (e.g., enhanced mobile broadband (eMBB)) and a second transmission of a second service type (e.g., ultra-reliable low-latency communication (URLLC)). The UE may identify a feedback codebook size for the first service type. The UE may multiplex a first feedback codebook having the identified feedback codebook size and generated for the first transmission with a second feedback codebook generated for the second transmission. Multiplexing the first and second feedback codebooks may produce a multiplexed feedback codebook. In some cases, the UE may perform the multiplexing based on a feedback multiplexing condition being satisfied. The UE may transmit the multiplexed feedback codebook in a control channel (e.g., a physical uplink control channel (PUCCH)) or a shared data channel (e.g., a physical uplink shared channel (PUSCH)).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in an idle mode in which the UE does not actively monitor for incoming transmissions. In some cases, the network may probe the idle UE by sending a paging early indication (PEI), which may trigger the UE to monitor paging occasions for incoming data. If the UE does not receive the PEI on the first PEI occasion, the UE may continue to monitor subsequent PEI occasions. However, the UE may stop monitoring subsequent PEI occasions once the data has been received. Accordingly, the network may indicate a stop trigger implicitly or explicitly to the UE. In some cases, the stop trigger may be an indication in a short message or downlink control information (DCI). Additionally, or alternatively, the UE may stop monitoring after receiving any downlink transmission.

The UE may determine SRS resources indicated by the first and second SRI values based on an association between control resource set (CORESET) pool index values and the first and second SRS resource sets. The UE may transmit the first PUSCH indicated by the first SRI value and the second PUSCH indicated by the second SRI value, in accordance with the determination.
