Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may group multiple carriers with transmission time intervals (TTIs) having different durations into different physical uplink control channel (PUCCH) groups. The UE may reserve power per each PUCCH group. Alternatively, the UE may reserve power per each TTI duration across the one or more PUCCH groups.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may configure a physical uplink shared channel (PUSCH) using shortened transmission time intervals (sTTIs), which may be referred to as a shortened PUSCH (sPUSCH), to transmit uplink control information (UCI) to a base station or other wireless device. The UE may use mapping rules, which may be based at least in part on a number of data symbols included in the sPUSCH, to map different types of UCI to different resource elements (REs) within the sPUSCH. A base station or other wireless device may use mapping rules, which may be based at least in part on a number of data symbols included in an sPUSCH, to determine one or more REs within the sPUSCH to monitor for different types of UCI.

Abstract: Methods, systems, and devices for wireless communication are described. Multiple transmission time intervals (TTIs) may be used for communications between a base station and user equipment (UE), where each TTI may have a data pattern scheduled by a base station. Each TTI may include respective symbol periods designated as reference or data symbol periods. In some examples, the UE may be configured to transmit a sounding reference signal (SRS) in a last symbol period of a TTI, and a base station may dynamically determine a data pattern for the TTI such that a temporally last symbol period is immediately preceded by a reference symbol period (e.g., based on the presence of the SRS). In such cases, the UE may configure a transient time within the preceding reference symbol period to avoid signal degradation of the SRS (or data transmitted within the same TTI).
