Abstract: This disclosure provides methods, devices, systems, and computer programs encoded on storage media, for clear channel assessment (CCA) for a wide bandwidth channel. For example, a wide bandwidth channel may have a bandwidth that is greater than 160 MHz bandwidth. An example wide bandwidth channel has a 320 MHz bandwidth. The CCA techniques include detection thresholds that may be used for wide bandwidth channels. In some implementations, a CCA process may be extended to include assessments of extended portions of a wide bandwidth channel (such as a tertiary 80 MHz bandwidth channel and a quaternary 80 MHz bandwidth channel). In some implementations, a CCA process may be extended to use an assessment of a secondary channel of the wide bandwidth channel that has a 160 MHz bandwidth.

An access point (AP) may identify a sequence of on symbols and off symbols for transmission to a wake-up radio (WUR) of a wireless device. The AP may assign a modulation symbol from a set of possible modulation symbol waveforms to at least each on symbol in the sequence. The modulation symbol waveforms may be assigned to sequential on symbols in a random or pseudorandom order, e.g., by applying a random phase rotation to a stored modulation symbol waveform, by applying a random cyclic shift to a stored modulation symbol waveform, or by applying a random or pseudorandom phase-shift keying value to each subcarrier in a multicarrier system to generate a modulation symbol waveform. The AP may transmit the sequence to the WUR based at least in part on the assigned modulation symbol waveforms.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may implement polar coding to generate codewords for transmission, for example, in a physical broadcast channel (PBCH). The base station may identify a subset of the bandwidth allocated for PBCH transmission (e.g., corresponding to a bandwidth for a synchronization signal), and may assign sub-channels to information bits based on the identified bandwidth subset. The base station may generate a codeword based on the assigned sub-channels, and may map a subset of encoded bits for the codeword to the subset of the bandwidth such that the subset of encoded bits includes bits corresponding to the assigned subchannels for the information bits. A user equipment (UE) may receive the encoded bits in the subset of the bandwidth, and may decode the subset of encoded bits to determine the information bits.
