Problems solved by technology

[0003] However, the existing access methods may cause the terminal to access an inappropriate TP (for example, RRH), that is, the channel between the terminal and other TPs (for example, a macro base station in a heterogeneous network deployment scenario) Strong interference will be caused to the channel between the terminal and the TP, so that the terminal cannot normally perform communication services through the TP, thereby reducing the access reliability of the terminal

Abstract

Embodiments of the present application provide an access method and device. In this embodiment of the present application, the terminal obtains the quality information of the reference signal after the precoding of the channel corresponding to each transmission point according to the first precoding matrix and the reference signals sent by the first transmission point and the second transmission point, In this way, the terminal can obtain the quality information of the precoded reference signal more accurately, so that the first transmission point can switch the terminal to an appropriate second transmission point, so as to realize the splitting among various transmission points, Therefore, the access reliability of the terminal is improved.

Description

technical field [0001] The present application relates to communication technologies, and in particular to an access method and device. Background technique [0002] In a wireless communication system such as a heterogeneous network deployment scenario, a cell ID may correspond to a transmission point (Transmission Point, TP), or a cell ID may also correspond to multiple TPs, and each TP usually has a different reference signal ( Reference Signal (RS) resources can be distinguished by different indexes, for example, virtual identifiers, etc. Wherein, the TP may include an access point (Access Point, AP), a macro base station, and a low-power node, for example, a micro base station (Micro), a pico base station (Pico), a remote radio head (Remote Radio Head, RRH), Relay device (Relay) and femto base station (Femto). Each TP needs to send RS configuration information indicating the RS resource corresponding to the TP to the terminal, so that the terminal can use the RS config...
