US Patent 12022402 Uplink transmission techniques in low latency wireless communication systems

Symbol alignment and power scaling are provided for different length transmission time intervals (TTIs) within predefined boundaries, such as boundaries of a slot of a subframe. Described techniques provide for identifying time and/or frequency resources for one or more TTIs and allocating such resources based on a location within a subframe, pilot signals that may be transmitted using the resources, other processing timelines, or any combination thereof. In some cases, a power allocation for symbols within a TTI may be determined based on the allocated resources for the TTI. Frequency hopping patterns and power scaling for three-symbol TTIs are also provided.
