Embodiment 1

[0099] see image 3 , image 3 It is a flowchart of an application example of a method for determining a primary site or a primary cell of a user equipment provided by an embodiment of the present invention. In this embodiment, the base station and the user equipment agree on the M (M is greater than or equal to one) CSI- The transmission point corresponding to the Nth (N is greater than or equal to one) CSI-RS configuration information in the RS configuration information is used as the primary site, or the cell corresponding to the transmission point is used as the primary cell, where N≤M, or, the The transmission point corresponding to the CSI-RS configuration information sent on a certain port in at least one CSI-RS configuration information is determined as the primary site, or the cell corresponding to the transmission point is determined as the primary cell. In this embodiment, the first CSI-RS configuration information as an example. After the user enters the network,...

Embodiment 2

[0122] The difference between the second embodiment and the first embodiment is that in the first embodiment, after the user equipment accesses the network, the user equipment determines which transmission point corresponding to the CSI-RS configuration information from at least one received CSI-RS configuration information It is the primary site, or the cell corresponding to the transmission point is the primary cell; and in the second embodiment, during the handover process of the user equipment, the base station sends a handover instruction command (Handover Command message) to the terminal to provide at least one CSI of the target cell -RS configuration information. The user equipment determines from at least one piece of received CSI-RS configuration information that the transmission point corresponding to which CSI-RS configuration information is the target primary site, or the cell corresponding to the transmission point is the target primary cell, and in the second embo...

Embodiment 3

[0124] see also Figure 4 , Figure 4 It is a flowchart of an application example of another method for determining the primary site or primary cell of the user equipment provided by the embodiment of the present invention. After the user equipment accesses the network, the difference between the third embodiment and the first embodiment is:

[0125]Step 401: the base station configures the first CSI-RS configuration information for the user equipment, and sends the first CSI-RS configuration information to the user equipment;

[0126] In this step, the transmission point corresponding to the first CSI-RS configuration information configured by the default base station is the primary site, or the primary cell of the cell corresponding to the transmission point;

[0127] Step 402: The base station configures at least one CSI-RS configuration information for the user equipment, and sends the at least one CSI-RS configuration information to the user equipment;

[0128] In this ...

Abstract

Embodiments of the present invention disclose a method, measurement method, information sending method and apparatus for determining a primary site or a primary cell of a user equipment. The method for determining the primary site or primary cell of a user equipment includes: receiving a message sent by a network side. The at least one signal state information configured for the user equipment refers to the signal CSI-RS configuration information; the transmission point corresponding to one CSI-RS configuration information in the at least one CSI-RS configuration information is determined as the primary site, or the transmission point The cell corresponding to the point is determined as the primary cell. The present invention solves that in the prior art, in the case of CoMP, the user equipment cannot determine which transmission point sending CSI-RS configuration information is the primary site that sends control signaling, or cannot determine which cell corresponding to the transmission point is the primary cell The problem.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for determining a primary cell or primary site of a user equipment, a measurement method, an information sending method and a device thereof. Background technique [0002] With the development of communication technologies, a new operation scenario, that is, Coordinated Multi-Point Transmission (CoMP, Coordinated Multi-Point) is introduced. Coordinated multi-point transmission can increase the rate of data transmission, for example, smooth transmission of video services, etc., thereby improving user satisfaction. [0003] At present, whether it is CoMP within a homogeneous network site, or a homogeneous network with high-power remote radio heads (RRHs, remote radioheads), or a heterogeneous network scenario with low-power RRH, in this heterogeneous network, tiny A zone may be an independent cell with an independent cell ID; or it may not be an independent...
