Abstract

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of the acknowledgement feedback for a positioning in RRC inactive state. The method comprises receiving, at a first device in a radio resource control, RRC, inactive state, information at least indicating a latency requirement for the first device to transmit an acknowledgement feedback for a reception of a message, the message being associated with a positioning of the first device and transmitted from a second device or a fourth device to the first device; and performing the transmission of the acknowledgement feedback for the reception of the message at least based on the information without changing the RRC inactive state. With the solution of the present disclosure, acknowledgement information report can be enabled to guarantee the reliability of positioning assistance data reception. It is benefit for the UE in the aspect of power saving, end-to-end positioning latency reduction and signaling overhead reduction.

Dependent claims

A first device comprising:

at least one processor;
and
at least one memory storing instructions that, when executed by the at least one processor, cause the first device at least to perform:
receiving information at least indicating a latency requirement for the first device to transmit an acknowledgement feedback for a reception of a message, the message being associated with a positioning of the first device and transmitted from a second device or a fourth device, wherein the first device is in a radio resource control (RRC) inactive state;
and
performing the transmission of the acknowledgement feedback for the reception of the message at least based on the information without changing the RRC inactive state,
wherein the information is received from the second device, and wherein performing the transmission of the acknowledgement feedback comprises:
determining, based on the latency requirement, a time window associated with the transmission of the acknowledgement feedback;
obtaining, from the information, an indication of a transmission mode and resources for transmitting the acknowledgement feedback for the reception of the message;
determining whether the acknowledgement feedback is allowed to be transmitted on the resources with the transmission mode before the time window expires;
and
in accordance with a determination that the acknowledgement feedback is allowed to be transmitted on the resources with the transmission mode before the time window expires, transmitting the acknowledgement feedback to the second device on the resources with the transmission mode,
wherein the resources comprising at least one of the following:
resources associated with a random access process between the first device and the second device,
resources associated with a configured grant allocated for the first device,
resources associated with a control channel between the first device and the second device, or
resources dedicate for the first device to transmit the acknowledgement feedback.
