    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: 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.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of control resource sets for reduced bandwidths. In a first aspect, a method of wireless communication includes receiving, from a base station at a user equipment (UE) having a first type, a master information block (MIB) within a physical broadcast channel (PBCH). The MIB includes CORESET size information and search space information for devices having a second type. The method also includes selecting a CORESET size from a plurality of preconfigured CORESET sizes based on a subcarrier spacing used to communicate with the base station. The method further includes monitoring a set of time and frequency resources to receive a message from the base station. The set of time and frequency resources has the selected CORESET size. Other aspects and features are also claimed and described.
