A method for estimating a time of arrival of a signal transmitted over a wireless channel, includes receiving the signal by a receiving device to produce a received signal; filtering by a filter either the received signal or a code sequence, wherein the filter is designed to produce a correlation output that is near causal; correlating the received signal with the code sequence to create the correlation output that is near causal; wherein near causal means that early side lobes and an early part of a main lobe of the correlation output are sufficiently suppressed in order to substantially reduce an impact of delayed multipath onto a first path component in the received signal, wherein the first path is in an operating region; identifying in the correlation output, an observation window associated with a main lobe in the correlation output; processing the observation window to determine a time of arrival of the first path component in the received signal.

An automobile device receives first data from one or more transmitters located in an automobile. A random access preamble is transmitted on an uplink carrier to a base station in response to a pre-defined condition being met based on at least one of the following: the first data; a value of an internal timer; and a user input. A first message is transmitted to a network server via the base station over a bearer. The first message is configured to trigger establishment of a connection to the network server. A second message is received from the network server via the base station over the bearer. The second message is configured to cause transmission of the first data to the network server. The first data is transmitted to the base station via an established bearer.

A base station may transmit one or more configuration parameters for a cell. The one or more configuration parameters may indicate a periodic resource configuration. The periodic resource configuration may be activatable by predetermined values of: a hybrid automatic repeat request process identifier (HARQ ID) field of a first downlink control information (DCI) format; and a redundancy version (RV) field of the first DCI format. The base station may transmit a DCI based on a second DCI format without at least one of the HARQ ID field or the RV field. The base station may activate the periodic resource configuration based on: a size of the HARQ ID field of the DCI and/or the RV field of the DCI being zero; and the periodic resource configuration being in an inactive state.
