A communication system for facilitating control over a function of a vehicle (102) comprises a base station (104) positioned in the vehicle (102) and a mobile communication unit (122). The base station (104) comprises a first transmitter for transmitting a signal to the mobile communication unit (122) and a first receiver for receiving a signal from the mobile communication unit (122). The base station (104) is further configured to cause the mobile communication unit (122) to operate in accordance with a limited-response duty cycle.

Improvements to signaling procedures for use in physical random access channel (PRACH)-based proximity detection are disclosed. Signaling and signaling processes from a serving base station may trigger a more efficient and reliable transmission of PRACH from related user equipment (UE). At the dynamic power nodes (DPNs) monitoring for such PRACH-based proximity, features are disclosed which establish neighbor lists for more efficient management of detection and proximity activation.

An apparatus configured to broadcast a wireless signal when a processing circuitry of the apparatus is in a non-active state. The broadcasted signals can be used to localize the apparatus when the apparatus is lost. The apparatus has a first processing circuitry configured to operate in an active power consuming mode and a non-active low power consuming mode. The apparatus further has a wireless transmit circuitry configured to be in an active mode and broadcast a wireless signal when the first processing circuitry switches operation mode from the active mode to the non-active mode. The first processing circuitry is powered by a battery supply, and the first processing circuitry may be configured to automatically switch from the active mode to the non-active mode when the supply voltage provided by the battery supply decreases below a threshold voltage, whereby the wireless circuitry will be broadcasting.

Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

Provided is a setting device and the like with which correct estimation of a communication band is possible. The setting device 101 has a transmission unit 102 that, on the basis of a first timing at which a first information processing device 401 transmits to a second information processing device 402 a first signal for measuring a communication band which pertains to a communication network 403, transmits to the second information processing device 402 a setting signal for setting a communication unit 407 of the second information processing device 402 to a communication-enabled state.

A user equipment transmits user equipment information, associated with a communication of the user equipment, to permit a base station to select a first bandwidth part, a second bandwidth part, or a third bandwidth part. The user equipment is configured to communicate by the first bandwidth part, the second bandwidth part, and the third bandwidth part. The user equipment receives, from the base station, an instruction to monitor the first bandwidth part, the second bandwidth part, or the third bandwidth part. The instruction is selected based on the user equipment information. The user equipment monitors, based on the instruction, the first bandwidth part, the second bandwidth part, or the third bandwidth part.

An overheating protection method for user equipment includes: sending a first signaling to a base station, the first signaling carrying indication information indicating that the user equipment has a capability of reporting a temporary capability of the user equipment; receiving a second signaling returned by the base station in response to the first signaling; and when the user equipment is overheated due to a wireless link configuration being too high, sending a third signaling for adjusting the wireless link configuration to the base station, the third signaling carrying assistance information indicating the base station to solve an overheating problem of the user equipment.
