Transmitting and receiving devices for v2v communication

Abstract

A transmitting device includes a plurality of antenna ports. Each antenna port is configured to transmit signals and is arranged at a different location, and each antenna port is assigned, depending on its location, a unique resource from a set of resources for signal transmission. Further, a receiving device, preferably on a vehicle, includes at least one antenna element configured to receive signals, and at least one processor configured to determine position and/or orientation information of the transmitting device of a received signal based on a resource from the set of resources for signal transmission.

What is claimed: 
     
         1 . A transmitting method, the method comprising:
 assigning, to each of a plurality of antenna ports arranged at different locations, a unique resource from a set of resources for signal transmission based on the respective location of the antenna port.   
     
     
         2 . The transmitting method according to  claim 1 , wherein
 the plurality of antenna ports are mounted to a vehicle or user equipment (UE) at different locations and are controlled by at least one processor of the vehicle or the UE.   
     
     
         3 . The transmitting method according to  claim 1 , wherein:
 each resource in the set of resources is a frequency resource, a time resource, or a code resource; or   each of the plurality of antenna ports is assigned, based on the respective location, a different frequency band or sub-band, a different time period or slot, or a different code.   
     
     
         4 . The transmitting method according to  claim 1 , wherein:
 a first set of the antenna ports that is arranged in a first spatial area is assigned a first logical subset of the resources, and   a second set of the antenna ports that is arranged in a second spatial area is assigned a second logical subset of the resources.   
     
     
         5 . The transmitting method according to  claim 1 , the method comprising:
 when transmitting a signal using at least one of the antenna ports, including identification information of a transmitting device into the signal.   
     
     
         6 . The transmitting method according to  claim 1 , the method comprising:
 when transmitting a signal using at least one of the antenna ports, including into the signal at least one of a total number of the antenna ports, a total number of resources contained in the set of resources, location information of the antenna port, or distance information between an antenna port and at least one other antenna port.   
     
     
         7 . The transmitting method according to  claim 1 , wherein the signal comprises at least one of:
 a synchronization signal (SS);   a physical broadcast channel (PBCH);   an SS PBCH block;   a reference signal (RS);   a Position Reference Signal (PRS); or   a discovery signal.   
     
     
         8 . The transmitting method according to  claim 1 , wherein:
 at least one antenna port is assigned multiple unique resources to transmit different signals at the same time;or   the at least one antenna port is configured to transmit different signals with separate beams.   
     
     
         9 . The transmitting method according to  claim 1 , wherein:
 at least one antenna port is configured to transmit and receive signals at the same time.   
     
     
         10 . A receiving method, the method comprising:
 determining position or orientation information of a transmitting device of a signal received by at least one antenna element based on a resource from a set of resources for signal transmission.   
     
     
         11 . The receiving method according to  claim 10 , the method further comprising:
 determining an angle of arrival at a receiving device; and   determining the position or orientation information of the transmitting device based on the angle of arrival.   
     
     
         12 . The receiving method according to  claim 11 , the method comprising:
 determining a first angle of arrival of a signal received by at least one antenna element and a second angle of arrival of the signal received by at least a second antenna element; and   determining the position or orientation information of the transmitting device based the first and the second angles of arrival.   
     
     
         13 . The receiving method according to  claim 10 , the method comprising:
 determining a time-difference between a first signal received in a first resource and a second signal received in a second resource at the same antenna element; and   determining the position or orientation information of the transmitting device based on the time-difference.
