Abstract
This document discloses a solution for providing a terminal device with one or more candidate cells for link setup. A network node providing the candidate cell(s) may compute a validity window for each candidate cell and indicate the validity window(s) to the terminal device. The terminal device may then perform the link setup with a candidate cell within the respective validity window of the candidate cell.
Claims18
A method comprising:
- receiving, in a terminal device of a cellular communication system, a message from a network node of the cellular communication system, the message comprising at least one information element indicating at least one candidate cell and at least one validity window for the at least one candidate cell, the at least one validity window defining at least one time window when link setup with the at least one candidate cell will be valid for the terminal device;
- selecting, in the terminal device, one of the at least one candidate cell for the link setup;
- and
- initiating, by the terminal device, the link setup with the selected candidate cell within a validity window associated with the selected candidate cell,
- wherein the at least one candidate cell comprises a plurality of candidate cells;
- and the method further comprises:
- comparing by the terminal device validity windows of the plurality of candidate cells and wherein said selecting is on a basis of the comparison.
4 more elements
An apparatus, comprising:
- at least one processor, and
- at least one non-transitory memory including a computer program code, wherein the at least one non-transitory memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- select for a terminal device of a cellular communication system, at least one candidate cell for link setup;
- determine at least one validity window for the at least one candidate cell, the at least one validity window defining at least one time window when the link setup with the at least one candidate cell will be valid for the terminal device;
- and
- cause transmission of a message to the terminal device, the message comprising at least one information element indicating the at least one candidate cell and a corresponding validity window for the terminal device to select for link setup based on a comparison of the at least one validity window.
3 more elements
An apparatus, comprising:
- at least one processor, and
- at least one non-transitory memory including a computer program code, wherein the at least one non-transitory memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- receive a message from a network node of a cellular communication system, the message comprising at least one information element indicating at least one candidate cell and at least one validity window for the at least one candidate cell, the at least one validity window defining at least one time window when link setup with the cell will be valid for the apparatus;
- select one of the at least one candidate cell for the link setup;
- and
- initiate the link setup with the selected candidate cell within a validity window associated with the selected candidate cell,
- wherein the at least one candidate cell comprises a plurality of candidate cells;
- and the apparatus is further caused to:
- compare validity windows of the plurality of candidate cells and wherein said selecting is on a basis of the comparison.
