Title:
SIDELINK CONNECTION MANAGEMENT BASED ON AN END-OF-DATA INDICATION
Document Type and Number:
WIPO Patent Application WO/2021/007802
Kind Code:
A1
Abstract:
Under current design assumptions on the NR sidelink, there is no periodic reference signal that is always sent; reference signals may, for example, accompany user traffic, and during periods with no traffic, there may be no corresponding reference signal. The present invention provides apparatus and methods for the Rx UE to distinguish these two cases and declare RLF appropriately when the link has been lost, while maintaining the link during periods of traffic inactivity when it has no basis to infer that the link quality has degraded. In some embodiments, methods of connection management between two UEs interacting over a sidelink interface are proposed. The described methods use an indication of the end of expected data, potentially together with a supervisory timer, to achieve substantially synchronous management of the connection between two peer UEs.
