TL;DR: Three cell selection methods associated with ICIC in heterogeneous networks in the LTE-Advanced downlink are investigated: signal-to-interference plus noise power ratio (SINR)-based cell selection, reference signal received power (RSRP)-basedcell selection, andreference signal received quality (RSRQ)-based Cell selection.

TL;DR: This paper investigates the application of inter-cell interference coordination (ICIC) in heterogeneous networks for the LTE-Advanced downlink where picocells are overlaid onto macrocells and investigates the influence that the CRS has on the control channel, i.e., physical control format indicator channel (PCFICH), and physical downlink control channel (PDCCH).

TL;DR: In this article, the beam generation part of a radio base station device comprises: a beam generator part 35 generating a directional beam for a macro UE by using antenna weight based on a beam pattern allocated to the macro UE in a macro cell having a first coverage area in the macro base station M-BS; and a coordination part 36 determining a beam patterns so that the beam pattern for the macro UEs in the MBS is the beep pattern whose interference power for a pico UE in the pico UEs is suppressed.

TL;DR: In this paper, the authors proposed a new radio communication system for realizing an excellent communication environment, which consists of a reception unit that receives a plurality of downlink signals that include a downlink signal to be retransmitted and are multiplexed and downlink control information that includes information necessary for processing of receiving the downlink message.
