Method for determining uplink auxiliary carrier of terminal and wireless network controller

Abstract

The invention discloses a method for determining an uplink auxiliary carrier of a terminal, which comprises the following steps that: a wireless network controller selects a downlink carrier adjacent to a downlink carrier which corresponds to a selected uplink carrier as a downlink auxiliary carrier for a specified terminal, wherein an uplink carrier which corresponds to the downlink auxiliary carrier is an uplink auxiliary carrier; the wireless network controller notifies a node B of transmitting the authorization of a node B scheduler to the terminal in a service high-speed downlink shared channel (HS-DSCH) cell corresponding to the downlink auxiliary carrier through an Iub or Iur port control signaling; and the wireless network controller notifies the terminal of taking a carrier generated by an uplink frequency point which corresponds to the downlink auxiliary carrier in the service HS-DSCH cell as the uplink auxiliary carrier through a Uu port control signaling. The invention also discloses the wireless network controller. The problem that the selected uplink auxiliary carrier of the terminal is not adjacent to a main carrier in the prior art is solved.

Description

technical field [0001] The present invention relates to carrier technology in wireless communication, in particular to a method for determining an uplink auxiliary carrier of a terminal and a radio network controller. Background technique [0002] In a wireless communication system, an air interface refers to an interface between a terminal (UE, User Equipment) and an access network (UTRAN, Universal Terrestrial Radio Access), referred to as a Uu interface, and is usually also called a wireless interface. The radio interface protocol is mainly used to establish, reconfigure and release various radio bearer services. [0003] The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) introduced the dual-carrier High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) technology in the eighth release (Rel-8). Carriers (main carrier and auxiliary carrier) to improve downlink bandwidth. The primary carrier corresponds to a serving...
