PATENT RESEARCH – PROBLEM SOLUTION APPROACH
As we have seen that V2X has two different connection types,
- DSRS (Dedicated Short-Range Communication)
- Cellular (using 4G/5G to communicate with a centralized infrastructure)
The most critical problem in standardization (i.e., 3GPP, IEEE) lies in cellular V2X communication and it seems evident from our recent patent surveys that “feedback collision” and “data synchronization” are the most prominent problems that need to be solved for enhancing the V2X communication.
We provide some exemplary patent evidence to showcase work regarding the concept of “feedback collision” and “data synchronization”.
WO2021029722A1
Assignee – LG
Problem Statement – The patent encounters the problems regarding feedback collision, resource utilization.
Solution Provided – The patent discloses determining a plurality of feedback (PSFCH) resources based on PSSCH and/or PSCCH related (transmission) parameters (e.g., PSCCH and/or PSSCH related slot index, PSCCH and/or PSSCH related subchannel index, source ID (Identity), destination ID, local group ID, etc.).
WO2021006500A1
Assignee – LG
Problem Statement – The patent encounters the issues related to the Near-Far problem that causes the UE unable to detect a specific PSFCH.
Solution Provided – The patent mentions about a receiving terminal that may determine the frequency domain and/or the code domain of the PSFCH resource based on at least one of SL RSRP, SINR, L1 source ID, and/or location information.
WO2020222560A1
Assignee – Samsung
Problem Statement – The patent encounters the problem regarding feedback collision.
Solution Provided – The patent discloses about transmitting a PSSCH/PSCCH to a UE and receiving in response a HARQ feedback. Also, it discloses that PSFCH with the highest priority of data packet indicated by PSCCH is preferentially transmitted.
WO2020222568A1
Assignee – Samsung
Problem Statement – The patent encounters a problem with the PSFCH collision.
Solution Provided – The patent discloses a reception UE that may determine the time domain resources and/or frequency domain resources and/or code domain resources for the PSFCH transmission. Also, a transmission UE determining the correspondence relationship between the time domain resources and/or frequency domain resources and/or code domain resources for the PSFCH transmission and at least one reception UE based on at least one of the following: a transmitter ID (i.e., source ID), a receiver ID (i.e., destination ID), a group ID, and an ID of the receiver within the group (i.e., an index within the group), the content of the feedback information.
WO2021067125A1
Assignee – Qualcomm
Problem Statement – The patent encounters a problem regarding feedback resource utilization.
Solution Provided – The patent talks about sidelink communications wherein a UE may use group size and its own UE member ID to derive a PSFCH resource to use for providing acknowledgement feedback of the packet.
PATENT RESEARCH – PROBLEM SOLUTION APPROACH
The DSRS-based V2X communication is described in IEEE standards (e.g., 802,11p, 802.11q, 802.11qt, 802.11 AS etc.) and the concerns regarding the DSRS-based V2X communication is an “insecure connection in short range packet communications”.
As per our analysis we have noticed some important classifications (e.g., H04L9/32, H04L9/3226 and H04L2209/00) which support solving the problems associated with the DSRS-based V2X communication regarding the concern for “insecure connection in short range packet communications”.
However, the DSRS-based V2X communication does not play an important role in today’s demand of V2X communication.
Some potential assignees who are working on concept of data security in DSRS-based V2X communication, are:
