An example method for wireless communication for a first device includes selecting a subset of synchronization signal block (SSB) occasions including SSB occasions within an SSB period, and wherein the subset of SSB occasions is associated with a pairing of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The example method also includes transmitting an SSB using at least one SSB occasion from the subset of SSB occasions. An example method for wireless communication for a user equipment (UE) includes selecting a synchronization signal pairing associated with a pairing of a PSS and a SSS, wherein the synchronization signal pairing maps to a subset of SSB occasions including SSB occasions within an SSB period, and also includes monitoring for an SSB at each SSB occasion from the subset of SSB occasions.

Abstract: Embodiments operate a multi-tenant cloud system. At a first data center, embodiments authenticate a first client corresponding to a first tenant ID and store resources that correspond to the first client, the first data center in communication with a second data center that is configured to authenticate the first client and replicate the resources. The first data center receives an Application Programming Interface (“API”) request for the first client corresponding to a change to the resources, and generates a change log and corresponding change event message in response to the API request. Embodiments compute a first hash corresponding to the first tenant ID of the change log to determine a first partition of a first queue at the first data center. The first data center pushes the change event message to the second data center via an API call.

Abstract: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

Abstract: Techniques described herein provide for the efficient usage of an RF channel for PRS transmissions by performing LBT sensing for a group of one or more vehicles (e.g., V2X vehicles) in a predetermined area by using an RSU. The RSU can determine a sequence in which an order for each vehicle in the group to transmit a respective PRS is defined, and provide the sequence to the group. The RSU may further perform the LBT functionality by listening to availability on the RF channel and, when the channel becomes available, the RSU can initiate this sequence by sending an initial PRS. This LBT sensing for a group can provide far more efficient usage of the RF channel than if LBT functionality were performed by each divisional vehicle.
