Abstract
Techniques for selecting a serving base station for a terminal by taking into account backhaul capability are described. The terminal may be within the coverage of multiple base stations, which may be of different types and may have different backhaul capabilities. One of the base stations may be selected as a serving base station for the terminal based on the backhaul capabilities of these base stations. The serving base station may also be selected based on additional criteria such as data or delay requirements of the terminal, transmit power capability of the terminal, characteristics of data for the terminal, etc.
Claims23
A method for wireless communication, comprising:
- obtaining a list of multiple base stations detected by a terminal;
- determining backhaul capability of each of the multiple base stations, the backhaul capability being determined from one or both of an aggregate data rate or a transmission delay between each respective base station and a data network;
- and
- selecting one of the multiple base stations as a serving base station for the terminal based on backhaul capabilities of the multiple base stations, wherein the selecting one of the multiple base stations comprises:
- determining an overall transmission capability of each of the multiple base stations based on transmission capability of a wireless direct or relay link for the base station and transmission capability of a wireless or wireline backhaul link for the base station, and
- selecting a base station with a largest overall transmission capability as the serving base station.
3 more elements
An apparatus for wireless communication, comprising:
- at least one processor configured to:
- obtain a list of multiple base stations detected by a terminal,
- determine backhaul capability of each of the multiple base stations, the processor configured to determine the backhaul capability from one or both of an aggregate data rate or a transmission delay between each respective base station and a data network,
- select one of the multiple base stations as a serving base station for the terminal based on backhaul capabilities of the multiple base stations,
- determine an overall transmission capability of each of the multiple base stations based on transmission capability of a wireless direct or relay link for the base station and transmission capability of a wireless or wireline backhaul link for the base station, and
- select a base station with a largest overall transmission capability as the serving base station.
