Methods and apparatus for cluster management in DSRC cooperative safety systems
First Claim
1. A method of a wireless communication by a first user equipment (UE), comprising:
- receiving a safety message from a second UE, wherein the received safety message includes a cluster indicator that indicates whether the received safety message is a first safety message type or a second safety message type, wherein the first safety message type is associated with and includes information about a single UE, and wherein the second safety message type is associated with and includes information about multiple UEs;
determining whether the received safety message is the first safety message type or the second safety message type based on the cluster indicator included in the safety message;
determining whether a proximity condition between the first UE and the second UE is satisfied based on the received safety message;
determining a mode of the first UE, the mode of the first UE being one of a standalone mode that indicates the first UE is not a member of any cluster of UEs, or a cluster member mode that indicates the first UE is a member of a cluster of UEs; and
determining, when the first UE is in a cluster member mode where the first UE is a member of a cluster of UEs associated with the second UE, whether to leave the cluster of UEs based on successful matching of an identifier in the received safety message with a leader UE identifier associated with the cluster of UEs and based on the determination of whether the proximity condition is satisfied.

Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus receives a safety message from a second UE. The received safety message includes a cluster indicator that indicates whether the received safety message is a first safety message type or a second safety message type. The first safety message type is associated with a single UE and the second safety message type is associated with multiple UEs. The apparatus determines whether the received safety message is the first safety message type or the second safety message type based on the cluster indicator included in the safety message. The apparatus determines whether a proximity condition between the apparatus and the second UE is satisfied based on the received safety message.

15. An apparatus for wireless communication, the apparatus being a first user equipment (UE) and comprising:
-
a memory; and at least one processor coupled to the memory and configured to; receive a safety message from a second UE, wherein the received safety message includes a cluster indicator that indicates whether the received safety message is a first safety message type or a second safety message type, wherein the first safety message type is associated with and includes information about a single UE, and wherein the second safety message type is associated with and includes information about multiple UEs; determine whether the received safety message is the first safety message type or the second safety message type based on the cluster indicator included in the safety message; determine whether a proximity condition between the first UE and the second UE is satisfied based on the received safety message; determine a mode of the first UE, the mode of the first UE being one of a standalone mode that indicates the first UE is not a member of any cluster of UEs, or a cluster member mode that indicates the first UE is a member of a cluster of UEs; and determine, when the first UE is in a cluster member mode where the first UE is a member of a cluster of UEs associated with the second UE, whether to leave the cluster of UEs based on successful matching of an identifier in the received safety message with a leader UE identifier associated with the cluster of UEs and based on the determination of whether the proximity condition is satisfied. - View Dependent Claims (16, 17, 18, 19, 20, 21)
