Abstract: An apparatus may receive a master information block and a synchronization signal (SS) block on a PBCH. The MIB may indicate an allocation associated with a CORESET. The apparatus may receive remaining minimum system information (RMSI) configuration information carried in the CORESET based on the allocation associated with the CORESET. The apparatus may determine a position associated with a downlink data channel based on a first value indicated by one of the MIB or the SS block in the PBCH and based on a second value indicated by the RMSI configuration information. The apparatus may receive data carried on the downlink data channel based on the position associated with the downlink data channel.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for operations with switching active bandwidth parts (BWPs), such as for radio link monitoring (RLM), beam failure recovery, random access, and/or other operations. As described herein, a UE may be configured with one or more sets of BWPs. The UE may determine/select the uplink and/or downlink BWP to use. For example, the UE can determine to use an active BWP or to switch to another BWP. The UE may use the BWP during operations, such as RLM, beam failure recovery, and/or random access, etc. for monitoring on the downlink and/or for transmitting on the uplink.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a bandwidth part switch from a first bandwidth part to a second bandwidth part. The user equipment may transition from the first bandwidth part to the second bandwidth part after determining the bandwidth part switch and based at least in part on a critical section defined for the transitioning from the first bandwidth part to the second bandwidth part. Numerous other aspects are provided.

Abstract: Various aspects directed towards generating a reference signal for pi/2-binary phase shift keying (BPSK) modulation are disclosed. In an example, a pi/2-BPSK sequence is selected from a plurality of candidate sequences. A reference signal is then generated based on the selected pi/2-BPSK sequence such that the reference signal is associated with a transmission of data modulated according to a t/2-BPSK modulation.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to random access channel (RACH) procedures in deployments where a RACH transmission may be sent on different UL carriers. An exemplary method performed by a base station includes receiving a random access (RA) preamble on a first component carrier (CC) of a plurality of CCs including at least one uplink (UL) CC and at least one supplemental uplink (SUL) CC and transmitting a response to the RA preamble, wherein the response indicates the first CC.

Abstract: Aspects of the present disclosure provide techniques for handling power transitions in transmissions in new radio (NR) devices. An exemplary method includes changing from using a first transmit power during a first portion of a transmission to a second transmit power during a second portion of the transmission, and taking action to mitigate a potential phase coherence loss associated with the changing from the first transmit power to the second transmit power.

Abstract: Various aspects described herein relate to techniques for timing control with filtering in orthogonal frequency division multiplexing (OFDM)-based wireless communications systems. In an aspect, the method includes determining whether time-domain filtering or frequency-domain filtering is used for a transmission signal waveform, and identifying a time delay based on a determination that the time-domain filtering is used for the transmission signal waveform. The method further includes applying a timing correction based on the identified time delay. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.
