Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may support beamforming communication techniques and may communicate using one or more beams. The UE may support a bandwidth part (BWP) hopping pattern and may perform a beam failure detection (BFD) procedure across the supported BWPs. While performing the BFD procedure, the UE may declare beam failure and may determine whether to switch to an anchor BWP to initiate a beam failure recover (BFR) procedure or to remain on an active BWP to initiate the BFR procedure. In some implementations, the UE may determine whether to switch to the anchor BWP or to remain on the active BWP to initiate the BFR procedure based on an indication from the base station.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect, a method of wireless communication performed by a user equipment (UE) includes receiving, from a base station, a remaining minimum system information (RMSI) physical downlink control channel (PDCCH) that includes downlink control information (DCI). The DCI indicates a configuration of resources associated with RMSI repetition or RMSI slot aggregation. The method further includes monitoring for one or more RMSI messages based on the configuration of resources. The monitoring includes monitoring for multiple repetitions of an RMSI message based on the configuration of resources being associated with RMSI repetition and monitoring for a single RMSI message that is divided across multiple slots based on the configuration of resources being associated with RMSI slot aggregation. Other aspects are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may monitor for a transmission of a synchronization signal block that includes a first portion generated using a first waveform type and a second portion using a second waveform type that is different than the first waveform type. The wireless device may detect the first portion of the synchronization signal block based on the first waveform type used for the first portion. After detecting the first portion of the synchronization signal block, the wireless device may process the second portion of the synchronization signal block based on information obtained from the first portion of the synchronization signal block. The information obtained from the first portion of the synchronization signal block may include timing information, frequency information, or both.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided for facilitating wireless communication at a UE. An example apparatus receives information scheduling communication with a base station on a first set of resources in a first frequency range and on a second set of resources in a second frequency range. The example apparatus communicates with the base station on the first set of resources in the first frequency range using a first set of parameters applicable to the first frequency range. Further, the example apparatus communicates with the base station on the second set of resources in the second frequency range using a second set of parameters applicable to the second frequency range.

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: Methods, systems, and devices for wireless communications are described. A transmitting device may generate a first time-domain reference signal sequence of a first sequence length, and may truncate the first sequence length to a second sequence length and may append a header portion and a tail portion to the truncated first time-domain reference signal sequence. The transmitting device may perform a discrete Fourier transform (DFT) on the truncated first time-domain reference signal sequence to generate a frequency-domain reference signal sequence associated with a phase constant, and may perform an inverse fast-Fourier transform (IFFT) on the result of the DFT. The transmitting device may then transmit the result of the IFFT to a receiving device, which may further process the signal by performing a fast-Fourier transform (FFT), dividing by the phase constant, and taking the conjugate of the received sequence.

Abstract: In one aspect of the disclosure, a UE may be configured to receive, from a base station, information indicating a reference point associated with at least one L1 measurement; determine a reporting value of the at least one L1 measurement based on a difference between the reference point and a measured value of the at least one L1 measurement; and transmit information indicating the reporting value to the base station. In another aspect, a RAN node can indicate to a UE that a reduced measurement report resolution is to be used for beam measurements in a measurement report. The reduced measurement report resolution is less than a first measurement report resolution previously indicated to be used for the beam measurements. Lower resolution can be obtained by using fewer bits to indicate one or more of the beam measurements. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the UE transmits the measurement report to the RAN node.
