US 2022/0046501 A1 · Link Determination and Establishment Method and Apparatus, Transmission System, and Satellite Communication System

Abstract

A link determination and establishment method and apparatus are provided. In the link determination method, a ground serving base station of User Equipment (UE) receives, from an air serving base station of the UE, link information of a primary link and configuration information of the air serving base station; the ground serving base station determines at least one cooperative base station of the UE and feature information of at least one secondary link according to the link information of the primary link and the configuration information of the air serving base station; and the ground serving base station sends, to the air serving base station and the at least one cooperative base station, indication information for establishing the at least one secondary link, the link information of the primary link, and configuration information of the ground serving base station.

Dependent claims

A link determination method, comprising:

receiving, by a ground serving base station of User Equipment (UE) from an air serving base station of the UE, link information of a primary link and configuration information of the air serving base station, wherein the primary link is a link between the ground serving base station and the air serving base station;
determining, by the ground serving base station, at least one cooperative base station of the UE and feature information of at least one secondary link according to the link information of the primary link and the configuration information of the air serving base station, wherein the secondary link is a link among the air serving base station, the cooperative base station and the ground serving base station;
and
sending, by the ground serving base station to the air serving base station and the at least one cooperative base station, indication information for establishing the at least one secondary link, the link information of the primary link, and configuration information of the ground serving base station.

A link establishment method, comprising:

sending, by an air serving base station of User Equipment (UE) to a ground serving base station of the UE, link information of a primary link and configuration information of the air serving base station, wherein the primary link is a link between the ground serving base station and the air serving base station;
receiving, by the air serving base station, link information of the primary link, configuration information of the ground serving base station, and indication information sent by the ground serving base station;
establishing, by the air serving base station according to the indication information sent by the ground serving base station, at least one secondary link with at least one cooperative base station and the ground serving base station;
and
performing, by the air serving base station, data or signaling transmission through the primary link and/or the at least one secondary link.

2 more elements

A link establishment method, comprising:

establishing, by a cooperative base station of User Equipment (UE) according to indication information sent by a ground serving base station of the UE, a secondary link with an air serving base station of the UE and the ground serving base station;
and
performing, by the cooperative base station, data or signaling transmission with the air serving base station through the secondary link.
