Problems solved by technology

[0007] However, when MF-Tx has more than two different downlink timing scenarios, the "advance" and "lag" in the selection principle of the above timing reference cell cannot determine which cell is the timing reference cell. The subframe timing difference corresponding to the joint feedback cell is not unique, therefore, the UE cannot determine which timing difference to report based on after measurement

Embodiment Construction

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0062] An embodiment of the present invention provides a timing reference cell processing method, such as figure 1 As shown, the execution subject of this method is a network side device, including:

[0063] S101. The network side device determines a first cell in each cell group according to a first preset criterion.

[0064] Wherein, the cell group is at least two cell groups. It should be noted that each cell group includes at least one cell.

Abstract

Embodiments of the present invention provide a timing reference cell processing method, device, and system, which relate to the communication field, so as to realize the determination of a timing reference cell in an application scenario where there are more than two different downlink timings. The method includes: a network side The device determines a first cell in each cell group according to a first preset criterion; and determines a timing reference cell in the first cells determined in each cell group according to a second preset criterion. The embodiment of the present invention is used for determining the reference cell and reporting the measurement of the UE under more than two different downlink timings.

Description

technical field [0001] The present invention relates to the communication field, in particular to a processing method and equipment for a timing reference cell. Background technique [0002] MF-Tx (Multiflow Transmission, multi-stream transmission) technology is to use the coordination between multiple cells in a base station or the coordination between multiple cells in multiple base stations to send different streams to a UE (User Equipment, user equipment). data. The cells participating in MF-Tx can be of the same frequency or adjacent frequency, and can belong to different sectors, and can even belong to different base stations. In addition, the downlink timing of the cells participating in MF-Tx can also be different. [0003] MF-Tx adopts a joint feedback method for the uplink feedback information of downlink data, that is, the feedback information of UE receiving data in multiple serving cells is in the same HS-DPCCH (High-Speed ​​Dedicated Physical Control Channel, ...
