Embodiment 1

[0146] This preferred embodiment provides a method for configuring F-TPICH information of uplink closed-loop transmit diversity on a ground interface. In this embodiment, after the RNC knows the RL Set and / or EDCH RL Set to which the RL belongs through the ground interface signaling, the RNC then configures the F-TPICH information of the RL of the serving link set cell to the base station NodeB through the ground interface signaling, The base station performs F-TPICH configuration on the cell to which the RL configured with F-TPICH information belongs according to the received configuration information.

[0147] Preferably, the ground interface refers to Iub port and / or Iur port.

[0148]Preferably, the RNC learns the RL Set and / or EDCH RL Set to which the RL belongs through ground interface signaling. Preferably, the ground interface signaling includes a radio link establishment response message, a radio link increase response message, and radio link reconfiguration Respond ...

Embodiment 2

[0152] This preferred embodiment provides a method for configuring F-TPICH information of uplink closed-loop transmit diversity on a ground interface. In this embodiment, when the RNC configures the uplink closed-loop transmission diversity information to the base station through the ground interface signaling, if the F-TPICH information needs to be configured to the serving link set cell, the RNC will perform all new, increased wireless links, or All new EDCH wireless links carry F-TPICH information to the base station; after receiving the request message, the base station allocates the RLSet and / or EDCH RL Set to which the RL belongs, and only reserves the F-TPICH of the RL of the serving link set cell. The TPICH information is configured; the RNC determines to reserve the F-TPICH information of the RL of the serving link set cell according to the RL Set and / or EDCH RL Set to which the RL belongs carried in the response message of the NodeB.

[0153] Preferably, the ground i...

Embodiment 3

[0156] This preferred embodiment provides a method for configuring F-TPICH information of uplink closed-loop transmit diversity on a ground interface. In this embodiment, the RNC obtains the cell set information of which cells on the NodeB side can perform soft combination through the audit response message or a new message, and then the RNC determines an RL Set, and then the RNC configures the serving link set cell through the ground interface signaling The F-TPICH information of the RL is sent to the base station NodeB, and the base station configures the F-TPICH for the cell to which the RL configured with the F-TPICH information belongs according to the received configuration information.

[0157] Through the technical solutions provided by the above three preferred embodiments, it can be solved that when the network controller configures the uplink closed-loop transmit diversity for the UE to the base station through the ground interface signaling, the F-TPICH information ...

Abstract

The invention discloses methods and device for configuring a fraction precoding indication channel. One method comprises the steps that an RL Set and / or an EDCH RL Set is acquired by an RNC, wherein each RL belongs to the RL Set; F-TPICH information of the RL of a service link set cell is determined by the RNC according to the acquired RL Set and / or the acquired EDCH RL Set; the F-TPICH information is sent to a base station by the RNC, and F-TPICH configuration is conducted on the service link set cell, wherein the RL corresponding to the F-TIPCH information belongs to the service link set cell. Through the methods and the device for configuring the fraction precoding indication channel, the accuracy of configuring the F-TPICH information through the service link set cell is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for configuring a Fractional Precoding Indicator Channel (F-TPICH). Background technique [0002] The multi-antenna technology achieves higher system capacity, wider cell coverage and better service quality by using multiple antennas at the sending end and (or) receiving end. Multiple antennas at the transmitting end and / or receiving end can be used to implement both transmit or receive diversity and spatial multiplexing. Among them, the transmit diversity technique is an anti-fading technique in the field of wireless communication in which at least two signals containing the same information are transmitted at the transmitting end. These signals carrying the same information originate from at least two mutually independent signal sources. Transmit diversity technology can be divided into three basic types of space, frequency, and time according to the str...
