HANDLING OF DEVICE-TO-DEVICE COMMUNICATIONS INTEREST INDICATION

摘要

This disclosure generally relates to handling of device-to-device communication interest indication. In one embodiment, a D2D UE may receive at its lower layer one or more first indicator for D2D communication interest indication from its higher layer during a time period of disconnection with its serving base station. The UE generates a second indicator for D2D communication interest indication based on the received first indicator(s). The second indicator is used to record or represent the latest first indicator for the UE's D2D communication interest indication received during the time period of disconnection. Once the connection with a base station is successfully reestablished, the UE reports to the re-established base station the generated second indicator to inform its D2D communication interest.

主权项

1. A method, comprising:
receiving, from a higher layer of a user equipment, at least one first indicator for device-to-device (D2D) communication interest indication during a time period when the user equipment experiences disconnection with a first base station originally serving the user equipment; generating a second indicator for D2D communication interest indication based on the received at least one first indicator, wherein the second indicator represents the latest first indicator; and reporting, in response to successful connection re-establishment with a second base station, the generated second indicator to the second base station.
