Problems solved by technology

Since such measurement reports are only available after the radio link is established and are sent infrequently, it is difficult to achieve CoMP gain for signaling and data transfers during the radio link establishment phase and short data transfers

Abstract

The present disclosure relates to a cell selection scheme. In one embodiment, there provides a method for performing a cell selection for a UE at a primary serving cell of the UE in a CoMP cluster including the primary serving cell and one or more candidate cells, the method comprising the steps of: receiving PRACH measurements for the UE from the candidate cells; and selecting from the candidate cells one or more cells for the UE as its secondary serving cells based on the received PRACH measurements.

Description

technical field [0001] The present disclosure relates to cell selection, and more particularly, to a method and device for performing cell selection in a CoMP communication system. Background technique [0002] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0003] Currently, a coordinated multi-point (CoMP) scheme is under consideration for both the uplink (UL) of the HSPA and LTE systems. The main idea of ​​UL CoMP is to form a pool of several sector antennas between base station sites and / or within a base station site, and process the received multi-antenna signals in a central processing unit. Signals that were previously considered inter-cell interference can now be considered useful signals. In the case of using multiple antennas, the detection of multiple user signals can be done in a linear way (for example, the method...
