Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for identification of a slot format for a set of slots where at least one slot format of the set is an subband full-duplex slot (e.g., includes uplink and downlink resources separated in a frequency domain). The base station may transmit one or more semi-persistent scheduling configurations to a UE. The UE may identify semi-persistent scheduling occasions for receiving a downlink communication based at least in part on the SPS configurations matching the format of the slot, the periodicity of the slot formats of the set, or other considerations. The UE and the base station may communicate based at least in part on the determined semi-persistent scheduling occasions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station via a first instance of a periodic data burst, where the periodic data burst may include one or more uplink or downlink transmissions scheduled on a first bandwidth part (BWP). The UE may start a bandwidth switching timer at the beginning of the first instance of the periodic data burst, and determine whether the bandwidth switching timer has expired upon expiration of an inactivity timer that was triggered by receipt of one or more downlink control channel messages. The UE may operate, based on the determination, on one of the first BWP or a second BWP during at least a portion of a time period that extends from the expiration of the inactivity timer and a beginning of a second instance of the periodic data burst.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to estimate, during a first time interval, at least one of a first interference level for a first radio access technology (RAT) caused at least in part by a second RAT, a second interference level for the second RAT caused at least in part by the first RAT, or a combination thereof. The UE may transmit a control message to a base station using the first RAT based on at least one of the first estimated interference level, the second estimated interference level, or a combination thereof. The UE may then communicate, based on the control message and during a second time interval, with the base station using the first RAT and with a wireless device using the second RAT, the second time interval being after the first time interval.

Abstract: Techniques for transmission of Ultra-Reliable Low-Latency Communications (URLLC) data over Time Division Duplex (TDD) using a URLLC configuration for a TDD subframe are disclosed. The techniques include determining that data scheduled for transmission using a TDD band over a TDD subframe includes Ultra-Reliable Low-Latency Communications (URLLC) data, and in response, utilizing a URLLC subframe configuration for the TDD subframe. The URLLC subframe configuration includes downlink intervals and uplink intervals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a first sub-slot periodicity for downlink semi-persistent scheduling (SPS). The UE may receive a plurality of transmissions according to the first sub-slot periodicity in a first slot, wherein the first sub-slot periodicity enables receiving the plurality of transmissions within a single slot. The UE may transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a second slot, wherein the second slot includes a plurality of physical uplink control channels (PUCCHs) with a second sub-slot periodicity, and wherein the HARQ-ACK information is associated with the plurality of transmissions.
