Abstract
Systems, methods, apparatuses, and computer program products for mobility failure evidence-related operations. A UE may measure, record, and report a channel access waiting (CAW) time period that elapsed from having a handover-related message in a transmission buffer until a channel for transmission of the handover-related message was obtained or until an acknowledgement or negative acknowledgement from a receiver of the handover-related message was received. The CAW time period information may be provided to a network node, and the network node may control mobility robustness optimization based on the received information.
Claims17
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- measure, during a handover procedure of a user equipment, one or more channel access waiting time periods associated with transmitting at least one handover-related message between a first network node and the user equipment;
- store information comprising the one or more measured channel access waiting time periods;
- and
- provide, to a second network node, the information comprising the one or more channel access waiting time periods,
- wherein the one or more channel access waiting time periods start with having an associated handover-related message in a transmission buffer and ends with obtaining a channel for transmission of the associated handover-related message or receiving an acknowledgement or negative acknowledgement from a receiver of the associated handover-related message.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- receive, from a further apparatus, information comprising one or more channel access waiting time periods associated with transmitting at least one handover-related message between a first network node and a first user equipment;
- and
- control mobility robustness optimization based on the received information,
- wherein the one or more channel access waiting time periods start with having an associated handover-related message in a transmission buffer and ends with obtaining a channel for transmission of the associated handover-related message or receiving an acknowledgement or negative acknowledgement from a receiver of the associated handover-related message.
A method, comprising:
- measuring, during a handover procedure of a user equipment, one or more channel access waiting time periods associated with transmitting at least one handover-related message between a first network node and the user equipment;
- storing information comprising the one or more measured channel access waiting time periods;
- and
- providing, to a second network node, the information comprising the one or more channel access waiting time periods,
- wherein the one or more channel access waiting time periods start with having an associated handover-related message in a transmission buffer and ends with obtaining a channel for transmission of the associated handover-related message or receiving an acknowledgement or negative acknowledgement from a receiver of the associated handover-related message.
