Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a physical uplink control channel (PUCCH) sequence for a set of PUCCH repetitions, wherein the PUCCH sequence is based at least in part on a PUCCH payload size. The UE may transmit the set of PUCCH repetitions using the PUCCH sequence. Numerous other aspects are provided.

A method includes generating a first DM-RS for V2X communication and a second DM-RS for V2X communication, the first DM-RS for V2X communication being mapped in a first symbol in a first slot of a subframe, the second DM-RS for V2X communication being mapped in a second symbol in the first slot; generating a third DM-RS for V2X communication and a fourth DM-RS for V2X communication, the third DM-RS for V2X communication being mapped in a first symbol in a second slot of the subframe, the fourth DM-RS for V2X communication being mapped in a second symbol in the second slot; and transmitting the first DM-RS for V2X communication, the second DM-RS for V2X communication, the third DM-RS for V2X communication, and the fourth DM-RS for V2X communication. The first DM-RS is generated based on a first group-hopping, and the second DM-RS is generated based on a second group-hopping.

A method for synchronization of an emitter of FBMC system with a RACH channel. On the emitter, a pseudo-random sequence with an initial offset in relation to a reference sequence is inserted into the spectral band of the RACH channel. On the receiver, the sequence received on the RACH channel is estimated using a sliding FFT using a starting point and correlated with the reference sequence. The position of the starting point leading to the highest correlation peak is selected as well as the correlation position corresponding to this peak, with these two positions making it possible to determine the offset of the sequence received with the reference sequence. This offset is transmitted to the emitter and the latter deduces from it a delay to be compensated in the emission in order to synchronize with the receiver.

A communications terminal comprises an encoder configured to encode a digital data signal to generate an encoded signal, a scrambler configured to scramble the encoded signal based on a scrambling signature, and a modulator configured to modulate resulting data frames for transmission via a random access communications channel. Each frame comprises a data payload, including a block of the scrambled signal, and a header, including a start of frame (SOF) sequence associated with the scrambling signature. Use of the SOF sequence for each frame provides a synchronization reference and serves to designate the associated scrambling signature for decoding the respective data payload. Use of the SOF sequence for each frame further serves to distinguish between the data frame and data frame(s) originating from further communications terminal(s), transmitted via a common time slot of the channel, for which different scrambling signature(s) were used to scramble respective encoded signal(s) thereof.

The present disclosure relates to an information processing device, an information processing method, and a program each capable of measuring a position and a posture by using sound without bringing discomfort to a user. A spread code signal emitted from each of multiple sound output blocks present at known positions, shifted to a frequency band that is not easily perceivable for a human sense of hearing, and based on a spread code to which spread spectrum modulation has been applied is received. The received spread code signal of a sound signal is reversely shifted. The own absolute position and the own absolute posture are calculated on the basis of the reversely shifted spread code signal, and angular velocity and acceleration detected by an IMU. The present disclosure is applicable to a game controller and an HMD.

Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first user equipment (UE) includes transmitting, to a second UE, a first sidelink synchronization block (S-SSB) in a first subset of a bandwidth, wherein the first S-SSB comprises a first sequence shift and a first identifier associated with the first UE and transmitting, to the second UE, one or more additional S-SSBs in one or more additional subsets of the bandwidth, wherein the one or more additional S-SSBs comprises at least one of a second sequence shift different from the first sequence shift or a second identifier associated with the first UE different from the first identifier associated with the first UE.

The first DM-RS is generated based on a first group-hopping, and the second DM-RS is generated based on a second group-hopping.

Mechanisms for interferer detection can detect interferers by detecting elevated signal amplitudes in one or more of a plurality of bins (or bands) in a frequency range between a maximum frequency (f.sub.MAX) and a minimum frequency (f.sub.MIN). To perform rapid interferer detection, the mechanisms downconvert an input signal x(t) with a local oscillator (LO) to a complex baseband signal x.sub.I(t)+jx.sub.Q(t). x.sub.I(t) and x.sub.Q(t) are then multiplied by m unique pseudorandom noise (PN) sequences (e.g., Gold sequences) g.sub.m(t) to produce m branch signals for I and m branch signals for Q. The branch signals are then low pass filtered, converted from analog to digital form, and pairwise combined by a pairwise complex combiner. Finally, a support recovery function is used to identify interferers.

Systems and methods are described for wake-up signaling of user equipment (UE). The systems and methods can include at least generating, by the BS, a wake up signal (WUS), wherein the WUS includes a length-131 Zadoff-Chu (ZC) sequence and a Gold sequence for radio equipment-level (RE-level) scrambling, and transmitting, by the BS, the WUS to a user equipment (UE) in a paging group associated with the WUS.
