Abstract

Official abstract text for this publication.

To provide a radio base station apparatus, mobile terminal apparatus and transmission power control method for enabling conventional inter-cell interference reduction techniques and ULCoMP to be used together, a radio base station apparatus of the invention is characterized by having a ULCoMP processing section (2085) that applies ULCoMP to a mobile terminal (1001) when a difference (PL2−PL1) between a path loss PL1 between the mobile terminal (1001) and a base station apparatus (2001) connected to the mobile terminal (1001) and a path loss PL2 between the mobile terminal (1001) and a base station apparatus (2002) with the lowest path loss for the mobile terminal (1001) is within a predetermined range, and a transmission power control section (2089) that performs transmission power control for application of ULCoMP when the ULCoMP is applied, while performing transmission power control for non-application of the ULCoMP when the ULCoMP is not applied.

First claim

Opening claim text (preview).

The invention claimed is: 1. A radio base station apparatus comprising a processor and a memory, the processor comprising: a multiple point reception processing section configured to apply uplink coordinated multiple point reception to a mobile terminal apparatus when a difference (PL 2 -PL 1 ) between a first pass loss PL 1 between the mobile terminal apparatus and a first radio base station apparatus connected to the mobile terminal apparatus and a second pass loss PL 2 betwee…
