Abstract: The present invention discloses an urban traffic velocity estimation method based on multi-source crowd sensing data. This method, based on roadside pedestrian data and road navigation data collected by smart phones, obtains a final estimated velocity through the steps of missing data filling, self-view velocity aggregation and multi-view velocity fusion. This fine-grained large-scale urban traffic velocity estimation method can achieve velocity estimation on all types of roads, including suburban road sections and paths, instead of just focusing on main roads in a city center. According to the present invention, based on data driving, the urban traffic velocity estimation method does not need to install additional devices on roads, and is low in cost and high in universality. Compared with the prior art, the urban traffic velocity estimation method has higher practicability, theoretical property and applicability, and is of great significance for improving traffic management and planning.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a user equipment (UE) may access a network or cell using a random access (RACH) procedure. A base station may allocate dedicated RACH resources and common RACH resources for the UE to transmit a RACH preamble message on and may convey a configuration for the UE. In some cases, the UE may perform multiple transmissions of the RACH preamble message in the dedicated RACH resources, and based on the configuration may determine whether to perform a single or multiple transmissions of the RACH preamble message in the common RACH resources. The UE may transmit the messages using the same or different uplink transmit beams, and the base station may receive the messages using the same or different uplink reception beams. These multiple transmissions may reduce latency and improve reliability of the RACH procedure.
