Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Certain aspects of the present disclosure provide techniques for carrier independent signal transmission and reception. Certain aspects provide a method for wireless communication. The method includes applying, at a device, a phase correction to a first signal to compensate for a difference between a first zero tone location comprising a first frequency and a second zero tone location comprising a second frequency. The method further includes one of: transmitting the first signal after applying the phase correction; or receiving the first signal prior to applying the phase correction.

Abstract: Certain aspects of the present disclosure provide techniques and apparats for remaining minimum system information (RMSI) physical downlink control channel (PDCCH) monitoring. A method for wireless communications by a user equipment (UE) is provided. During initial access of a cell, the UE determines a default first periodicity to monitor for at least a first PDCCH scheduling RMSI. After the initial access, the UE determines a second periodicity to monitor at least a second PDCCH scheduling RMSI based on the default first periodicity or based on an indication received in a previous RMSI from the cell. The UE monitors for at least the first PDCCH during initial access at the default first periodicity and monitors for at least the second PDCCH at the second periodicity after the initial access.

Abstract: Aspects of the present disclosure describe synchronizing frequency and/or timing in a wireless communication system. A synchronization channel frequency can be determined as one of a plurality of possible synchronization channel frequencies within a frequency band. A tone of one or more synchronization signals that corresponds to the synchronization channel frequency can be punctured, and the one or more synchronization signals can be transmitted as centered around the synchronization channel frequency.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a network entity to indicate a network energy savings (NES) mode status for one or more cells in a common control message sent to a group of user equipments (UEs). The network entity may include one or more NES mode indications in a downlink control information (DCI) message that activates or deactivates a discontinuous transmission (DTX) configuration, a discontinuous reception (DRX) configuration, or both for one or more cells. The DCI message may include the DTX and the DRX information in one or more respective information blocks corresponding one or more serving cells for the group of UEs, and the network entity may include the one or more NES mode indications in the one or more information blocks.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes establishing a first component carrier as a primary cell for the user equipment (UE) and a second component carrier as a secondary cell for the UE, receiving primary cell configuration information for the second component carrier while the second component carrier is the secondary cell for the UE, receiving a control message triggering a switch of the primary cell from the first component carrier to the second component carrier, and establishing the second component carrier as the primary cell for the UE based on the control message and in accordance with the primary cell configuration information associated with the second component carrier.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving user equipment (UE) may transmit a first measurement that is based at least in part on a first reference signal, from a base station, that is to be reflected via a passive device. The receiving UE may transmit a second measurement that is based at least in part on a second reference signal, from a transmitting UE, that is to be reflected via the passive device and a third reference signal from the transmitting UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein may support authentication schemes for wireless communications. A first wireless device may communicate one or more messages associated with an authentication scheme with a second wireless device. The one or more messages may indicate a capability of one or more of the devices, that the authentication scheme includes a symmetric or an asymmetric authentication scheme, or both. The first wireless device may receive a signal from the second wireless device. The signal may include a set of authentication bits. The first wireless device may determine an authenticity of the signal based on the set of authentication bits, the signal, at least one key associated with the authentication scheme, or a combination thereof. The authenticity may indicate whether the signal was sent from the second wireless device or another wireless device.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives, from a network entity, a channel state information (CSI) report configuration including a set of sub-configurations. Each sub-configuration in the set of sub-configurations corresponds to a transmission setting associated with a channel state information reference signal (CSI-RS). The UE further determines one or more selected CSIs corresponding to a subset of the set of sub-configurations, incorporates the one or more selected CSIs into one or more CSI reports, and transmits, to the network entity, the one or more CSI reports based on the incorporation.
