Systems and methods for maintaining voice communications between platooning vehicles, vehicles and other non-platooning vehicles, and with a Network Operations Controller (NOC) is disclosed. In various embodiments, the voice communications are maintained over a direct vehicle-to-vehicle link and/or a cellular link either between vehicles or with the NOC. Also disclosed is a PTT protocol with an interrupt feature that allows a first driver to interrupt a second driver while the second driver is transmitting. Also disclosed is using the system and methods for maintaining voice communications among drivers of tractor-trailer trucks operating in a platoon.

The present specification relates to a method for transmitting and receiving data in a wireless communication system supporting device-to-device (D2D) communication, and the method performed by a first terminal comprises the steps of: acquiring a resource pool used for D2D communication, wherein the resource pool includes either a scheduling assignment (SA) resource pool indicating a resource region through which an SA is transmitted or a data resource pool indicating a resource region through which D2D data is transmitted; transmitting, to a second terminal through the SA resource pool, the SA including information related to D2D data transmission; and transmitting the D2D data to the second terminal.

According to one embodiment, a wireless base station includes a transmitter and a receiver. The transmitter transmits a control signal and one or more operation signals to the second wireless communication terminal. The control signal instructs to transmit a signal that requests terminal-to-terminal communication between a first wireless communication terminal and the second wireless communication terminal. The operation signals are used for operating at least a part of the first wireless communication terminal. The receiver is capable of receiving at least one of a response signal or a data signal transmitted from the first wireless communication terminal to the second wireless communication terminal after the operation signals are transmitted.

Apparatus and methods for extending and enhancing wireless networks. An exemplary wireless network configured according to the disclosure uses in-service Wireless Network Clients (WNCs), such as mobile phones, laptops, etc., to extend and enhance the wireless network coverage via peer-to-peer sub-networks. In one implementation, each WNC is configured to operate as a Service Access Node (SAN) to other wireless client devices in the same network. The SAN provides peer-to-peer communications capabilities (to communicate with wireless clients) and gateway functionality (to aggregate data traffic over its own uplink communications), thereby enabling wireless clients to piggyback their data link onto the WNC. Peer Control Manager (PCM) software on each WNC enables, disables, and controls the service functions for that WNC in accordance with an overarching Peer Controller (PC) entity operated by an Access Point Controller/Core Network.

An operation method of a first communication node located in a vehicle may include: performing V2X communication with a second communication node using an original resource according to an original SPS configuration; when a congestion level in the original resource is not less than a predetermined threshold and at least one target base station supporting V2X communication is discovered, generating new SPS configuration to be applied to the serving base station and the at least one target base station by changing original SPS configuration; performing a message transmission and reception procedure with the at least one target base station for delivery of new SPS configuration; and performing V2X communication with the second communication node using first resource scheduled by the serving base station based on new SPS configuration and second resource scheduled by the at least one target base station based on new SPS configuration.

According to the teachings herein, a wireless device that is a candidate for operating in the cooperative positioning advantageously activates that mode in response to detecting a warning situation. In some embodiments, the detection and/or activation operations are autonomously undertaken by the wireless device. In other embodiments, the wireless communication network provides warning situation detection and/or control of the cooperative positioning mode. More generally, the wireless communication network maintains a database identifying those wireless devices within a given service area that are cooperative positioning mode candidatese.g., the devices having D2D communication capability and operational configurations that allow such operation. By the network providing such information in advance of a warning situation, the candidate devices have the information needed to efficiently discover or otherwise identify other such candidates.
