Embodiment Construction

[0019] In order to better understand the spirit of the present invention, it will be further described below in conjunction with some preferred embodiments of the present invention.

[0020] Protocol 36.819 specifies multiple CoMP related sets, which are CoMP Cooperating Set (CCS, CoMPCooperating Set), CoMP Transmission Set (CTS, CoMP Transmission Point(s) Set), CoMP Measurement Set (CMS, CoMP Measurement Set), and CoMP Resource Management Set (CRMS, CoMP Resource Management Set).

[0021] Specifically, the transmission points in the coordinated multi-point coordination set can directly participate in the actual data transmission on the time-frequency resource, and can also participate in the user scheduling / beamforming (beamforming) decision on the time-frequency resource as a candidate transmission point, thereby indirectly for data transfer. The CoMP transmission set is a subset of the Cooperating Set, in which the transmission points directly transmit data to the user equ...

Abstract

In LTE-A release 11 for measuring coordinated multi-point CoMP resources a CoMP resource management set CRMS and a CoMP measurement set CMS is defined (3GPP TR 36.819). The measurement is based on reference signal receiving power RSRP measurement of channel state information - reference signal CSI- RS resource. The measurement set used in a mobile station may be changed by a command (MAC-CE signalling element) from the base station. Problem: There might be situation where after the change the mobile terminal measures CSI-RS resources which are inactive (SCell). This would lead to a waste of energy in the UE. Solution: The UE stops measuring after the change (adding) and continues only after being commanded to by the base station.

Description

technical field [0001] The present invention relates to Coordinated Multi-Point (CoMP, Coordinated Multi-Point) in wireless communication, in particular to a method and device for managing Coordinated Multi-Point related sets in wireless communication. Background technique [0002] Coordinated multi-point transmission is a very promising technology in Long Term Evolution-Advanced (LTE-Advanced, Long Term Evolution-Advanced), which can effectively reduce inter-cell interference (ICI, inter-cell interference) and improve high Coverage of data rate, cell edge throughput and / or system throughput. At the same time, as a technology that is constantly developing and improving, multi-point collaboration must also have some problems that need to be solved urgently. For example, how to manage and configure various CoMP correlation sets is currently a research hotspot in the industry. Contents of the invention [0003] An object of the present invention is to provide a method and d...
