Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] First, combine figure 1 A method 100 for transmitting PCI information according to an embodiment of the present invention is described.

[0037] like figure 1 As shown, the method 100 includes: in S110, obtaining the frame offset of the F-PCICH; in S120, occupying the F-PCICH according to the update period of the PCI information, the time slot format of the F-PCICH of the user equipment and a PCI information The number of time slots above, determine the...

Abstract

The embodiment of the invention provides a method for transporting pre-coding controlling indication information, a base station and a user device. The method comprises the steps of: acquiring frame offset of a fractional pre-coding controlling indication channel (F-PCICH); according to an updating period of PCT information, an F-PCICH time slot form and a time slot number occupied by a piece of PCI information on the F-PCICH, determining a first time slot number set loading PCI information and determining a character position occupied by the PCI information in the time slot, wherein the PCI information corresponds to a pre-coding matrix; and sending an F-PCICH frame to the user device according to the frame offset and the time slot form, and loading the PCI information in the character position in the time slot corresponding to a time slot number in the first time slot number set. Based on the scheme above, the channel timing when the F-PCICH is used for transporting the PCI information is realized, so that the base station can feed back the PCI information to the user device conveniently, and the adaptive speed of upstream data to a channel condition can be facilitated to be improved, and the system performance can be improved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method, base station and user equipment for transmitting precoding control indication information in the communication field. Background technique [0002] With the rapid development of communication technology, Wideband Code Division Multiple Access (WCDMA), as one of the mainstream technologies of the third generation mobile communication system, has been widely researched and applied in the world. Currently, WCDMA has Released the 99th version (Release99, R99), the fourth version (Release4, R4) to the 10th version (Release10, R10) and other versions. [0003] F-DPCH (Fractional Dedicated Physical Channel, Partial Dedicated Physical Channel) is introduced in the sixth release (Release6, R6). The F-DPCH is a special downlink DPCCH (Dedicated Physical Control Channel, dedicated physical control channel), which is used to carry TPC (Transmission Power Control, transmi...
