Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the 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 persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] When data transmission in CoMP mode is performed between the network and the terminal device, different stations will transmit different channel state information reference signals to support the terminal device to perform channel measurement through the respective CSI-RS of multiple stations, so that the terminal device It is possible to perform data transmission using a plurality of stations corresponding to the CSI-RS. Terminal equipment is also ...

Abstract

The invention discloses a method and a device for cell switching. The method comprises the steps of: acquiring result of measurement on reference signals carried out by terminal equipment; determining a target base station of cell switching according to the measurement result; sending a switching request message to the target base station; and receiving a switching request confirmation message sent by the target base station, wherein the switching request confirmation message carries configuration information of at least one target CSI-RS or a confirmation instruction for confirming the configuration information of the at least one CSI-RS carried in the switching request message. The device comprises a first acquiring module, a first determining module, a first transmitting module and a receiving module. With the method and the device for cell switching provided by the embodiment of the invention, the terminal equipment can use a plurality of stations at the same time before and after cell switching, and thus business continuity of the terminal equipment during switching can be maintained.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and device for switching cells in the field of communications. Background technique [0002] In the Long Term Evolution (referred to as "LTE") R11 version, a new operation scenario will be introduced, that is, coordinated multi-point transmission / reception (Coordinated Multi-point, referred to as "CoMP"). The main benefit of implementing CoMP is that the rate of data transmission can be increased, for example, video services can be transmitted smoothly, thereby improving user satisfaction. Currently, there are four specific scenarios that need to be focused on for research, namely: [0003] Scenario 1: CoMP scenario within a homogeneous website; [0004] Scenario 2: A homogeneous network scenario with a high-power Remote Radio Head (RRH for short); [0005] Scenario 3: a heterogeneous network scenario with low-power RRH. In this scenario, a micro ce...
