Patent number: 11706831Abstract: A wireless device (100) is configured for dual mode V2X communications over multiple short range radio interfaces. The wireless device (100) is configured to transmit ITS messages over a first short range radio interface configured to operate according to a first communication standard (e.g. PC5 or IEEE 802.11p), and to receive ITS messages over both the first short range radio interface and a second short radio interface configured to operate according to a second communication standard. Implementing the transmitter chain of only one technology, either PC5 or IEEE 802.11p, at each wireless device (100) reduces complexity and mitigates co-channel and adjacent channel interference that is caused by uncoordinated and concurrent transmissions of different technologies from the same wireless device. Implementing receiver chains for both PC5 and 802.11p allows the wireless device (100) to receive signals in the ITS frequency band regardless of which technology the transmitting device is using.Type: GrantFiled: July 6, 2018Date of Patent: July 18, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Håkan Andersson, Maciej Muhleisen, Tomas Nylander, Evanny Obregon, Stefano Sorrentino, Erika Tejedor, Henrik Voigt, Yunpeng Zang

Patent number: 11109237Abstract: A first wireless node of a wireless communication system is associated with a first cell having a first cell identity. The first wireless node obtains information relating to a set of wireless nodes which use at least one overlapping communication resource that is also used by at least one second node in the first cell. The first wireless node generates a preamble containing: a first data field designating the first cell identity, and a second data field reflecting a respective identity of the wireless nodes in the set of wireless nodes which use the at least one overlapping communication resource. The first wireless node transmits a preamble signal containing the preamble, over a predefined set of resources in a shared resource structure of the wireless communication system thus informing about the wireless nodes that use overlapping communication resources.Type: GrantFiled: August 23, 2017Date of Patent: August 31, 2021Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Amitav Mukherjee, Reem Karaki, Evanny Obregon, Du Ho Kang
