Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a transmission power for a synchronization signal block (SSB) transmission by a base station, the indicated transmission power different than a default transmission power for SSB transmissions by the base station. The UE may determine a received power with which the SSB transmission is received at the UE. The UE may receive one or more downlink transmissions from the base station based at least in part on the received power for the SSB transmission and a difference between the default transmission power and the indicated transmission power for the SSB transmission.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide information identifying a first time offset between a first time associated with a measurement performed by the user equipment and a second time associated with a measurement gap or a time value of a serving cell of the user equipment, receive information identifying a second time offset between the second time and a third time, wherein the second time offset is based at least in part on the first time offset, and/or transmit a random access message at the third time based at least in part on the second time offset. A scheduling entity may coordinate a random access procedure associated with the random access message based at least in part on the second time offset. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information identifying a resource allocation for an uplink transmission of a transport block over multiple slots. The UE may transmit, to the base station, at least a portion of coded bits corresponding to the transport block based at least in part on a different uplink transmission being scheduled within the uplink transmission of the transport block over the multiple slots. 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 interleave a signal, that is to be transmitted using discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (DFT-s-OFDM), and a negative of the signal to obtain an interleaved signal prior to performing a DFT on the interleaved signal. The UE may transmit a DFT-s-OFDM signal that is based at least in part on the interleaved signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, Generally, a base station may send to a user equipment (UE) a configuration message, which may include an indication of one or more CSI-RS resources and one or more random access occasion indices. The UE may identify one or more random access occasions associated with the UE based on the CSI-RS resources, the random access occasion indices for the UE, and a random access occasion index reset time. The random access occasion index rest time may be based on a fixed time period. The random access occasion index reset time may be based on a number of CSI-RS resources. In some examples, the random access occasion index reset time may be based on a number of actually transmitted synchronization signal blocks (SSBs).

Abstract: Certain aspects of the present disclosure relate to methods and apparatus synchronization configuration in different operation modes using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications by a base station (BS) may include determining an operation mode of the BS, determining a transmission configuration of at least one of a one or more synchronization channels or a one or more synchronization signals based on the operation mode, and transmitting the one or more synchronization channels or the one or more synchronization signals based on the determined transmission configuration.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may be configured to transmit two or more consecutive transmissions that may be used for demodulation reference signal (DMRS) bundling. If criteria for DMRS bundling are not satisfied, the UE may generate dummy data to transmit during the skipped configured grant occasion, and may maintain phase continuity across the skipped configured grant occasion and any other PUSCHs in a set of uplink transmissions. In some examples, the UE may deprioritize DMRS bundling for sets of PUSCHs during which a PUSCH is to be skipped. If criteria for DMRS bundling are not satisfied, the UE may not maintain phase continuity across the set of PUSCHs, and may refrain from transmitting any data during the CG-PUSCH occasion.
