A radio frequency circuit includes a multilayer substrate, series arm circuits in a first path connecting the input/output terminals (T1 and T2) on the multilayer substrate, a parallel arm circuit in a second path connecting a node on the first path and a ground, a wiring A on the multilayer substrate connected to the input/output terminal (T1) as a part of the first path, a wiring B on the multilayer substrate connected to the input/output terminal (T2) as a part of the first path, and a wiring C on the multilayer substrate as a part of the second path. The parallel arm circuit includes an impedance variable circuit, the wiring A and the wiring B in a layer different from the multilayer substrate. When viewed in a plan view, the wiring C does not overlap with the wiring A and the wiring B.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may determine a grid allocation of single carrier resource blocks (SC-RBs) that defines a plurality of SC-RBs in a time domain and in a frequency domain. The first node may perform, to a second node, a frequency division multiplexed transmission associated with a single carrier waveform using one or more SC-RBs indicated in the grid allocation of SC-RBs. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may transmit a random access preamble to a base station as part of a random access procedure between the UE and the base station. To generate the random access preamble, the UE may repeat each time domain sample of a base sequence on a per-sample basis to obtain a repeated sequence that includes multiple repetitions of each time domain sample of the base sequence, with repetitions of the same sample being consecutive within the repeated sequence. The UE may perform such sample-wise repetition before adding a cyclic prefix (CP) to the repeated sequence or after adding a base CP to the base sequence.

A UE receives a configuration for a message A (Msg A) physical random access channel (PRACH) over a resource block (RB) set for a two-step random access channel (RACH) operation and receives one or more parameters for a Msg A physical uplink shared channel (PUSCH) configuration. The UE transmits a Msg A in a configured Msg A PRACH occasion and a Msg A PUSCH resource based on an RB set for the Msg A PRACH and the one or more parameters for the Msg A PUSCH configuration.
