Abstract: A wireless device (e.g., a UE or a base station) may identify a first subcarrier mapping associated with one or more redundant subcarriers. The one or more redundant subcarriers may correspond to one or more UWs in a UW-OFDM waveform. The wireless device may identify a second subcarrier mapping associated with one or more reference signals. A simultaneous application of the first subcarrier mapping and the second subcarrier mapping may be associated with one or more collisions. The wireless device may modify at least one of the first subcarrier mapping or the second subcarrier mapping to eliminate the one or more collisions. The wireless device may generate the UW-OFDM waveform based on the modified at least one of the first subcarrier mapping or the second subcarrier mapping. The wireless device may transmit a signal based on the generated UW-OFDM waveform.

Abstract: Aspects described herein relate to adding a set of redundant subcarriers to a set of data subcarriers to be transmitted in a unique-word orthogonal frequency division multiplexing (UW-OFDM) waveform, interleaving, based on a permutation matrix, the set of redundant subcarriers with the set of data subcarriers to generate a permutation of subcarriers, mapping the permutation of subcarriers as input to an inverse fast Fourier transform (IFFT), and generating the UW-OFDM waveform based on output of the IFFT. Other aspects relate to receiving and processing the UW-OFDM waveform.

Abstract: Certain aspects of the present disclosure provide techniques for providing direct current locations of bandwidth parts (BWPs) in a BWP hopping pattern. Certain aspects relate to a method for wireless communication by a user equipment (UE). In some examples, the UE may receive, from a base station (BS), a request for uplink direct current location information of the UE, wherein the UE is configured to transmit to the BS on an uplink according to a frequency hopping pattern for hopping between a plurality of uplink bandwidth parts corresponding to different frequency bandwidths. In some examples, the UE may transmit, to the BS, at least one uplink direct current location applicable to the plurality of uplink bandwidth parts. In some examples, the UE may transmit, to the BS, on the uplink according to the frequency hopping pattern.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless device determines a symbol configuration for transmission of SC-FDE waveform with zero gaps arranged between a communication channel part, RS part, and CP part. The SC-FDE waveform is transmitted to another wireless device, which processes the SC-FDE waveform.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first wireless device, an uplink communication using a first guard interval. The IAB may receive, from a second wireless device, a downlink communication using a second guard interval, a second length of the second guard interval being different from a first length of the first guard interval. The IAB may process the uplink communication and the downlink communication in a same fast Fourier transform window. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a semi-persistent scheduling (SPS) downlink communication. The UE may detect a collision between a configured uplink resource associated with a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the SPS downlink communication and a candidate synchronization signal block (SSB) position. The UE may transmit the HARQ-ACK for the SPS downlink communication in the configured uplink resource or in a deferred uplink resource in connection with detecting the collision. Numerous other aspects are described.

Abstract: A second base station may transmit, to a UE, an indication of a PCI associated with the second base station. The UE may transmit, to a first base station, a measurement report corresponding to the second base station. The UE may receive, from the first base station, a request for the CGI associated with the second base station based on the PCI associated with the second base station. The UE may receive, from a second base station, a first indication of a CGI associated with the second base station via a PDCCH or a PDSCH. The UE may transmit, to a first base station, a second indication of the CGI associated with the second base station based on the received first indication of the CGI. The CGI may be an NCGI. The UE may refrain from monitoring for a SIB 1 associated with the second base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted using a single carrier quadrature amplitude modulation (SC-QAM) waveform, wherein the SSB has a uniform bandwidth allocation for each of a primary synchronization signal (PSS) included in the SSB, a secondary synchronization signal (SSS) included in the SSB, and physical broadcast channel (PBCH) data included in the SSB. The UE may perform initial channel access based at least in part on the SSB. Numerous other aspects are described.

Abstract: Disclosed are techniques for positioning. A receiver measures a time of arrival (ToA) of a positioning reference signal (PRS) transmission of a first PRS sequence transmitted by a first transmitter, measures a ToA of a PRS transmission of a second PRS sequence transmitted by a second transmitter, and determines an observed time difference of arrival (OTDOA) as a difference between the ToA of the PRS transmission of the first PRS sequence and the ToA of the PRS transmission of the second PRS sequence, wherein the OTDOA is less than half a maximum differential delay expected between the PRS transmission of the first PRS sequence and the PRS transmission of the second PRS sequence, and wherein a repetition duration of the first PRS sequence and the second PRS sequence is greater than 10 milliseconds (ms) and at least twice the maximum differential delay.
