PURPOSE: To realize excellent two-way communication processing with a high frequency utilization efficiency without complicated configuration of a transmission reception circuit when the information amount in an outgoing way from a base station to a terminal equipment is considerably more than an incoming...
A METHOD FOR FREQUENCY ALLOCATION AND ASSIGNMENT IN WIRELESS COMMUNICATION SYSTEMSA single-cell wireless communication system is partitioned into n sectors, to which channels are allocated from two groups of non-adjacent channels. If the available channels are consecutively numbered from lowest to ...
1. A frequency allocation method, in a wireless base station apparatus communicating wirelessly with a terminal apparatus, for dividing a cell that is a communication range of the wireless base station apparatus into six areas in a clockwise direction, and allocating a frequency to each of the di...
This paper proposes a dynamic fractional frequency reused cell architecture that simplifies the problem of subcarrier allocation with frequency reuse in multicell OFDMA networks. The architecture divides the cell surface into two overlapping geographical regions and orthogonally allocates subcarriers, which ...
CONTROL STATION, RADIO COMMUNICATION SYSTEM, AND FREQUENCY ALLOCATION METHOD PROBLEM TO BE SOLVED: To improve the utilization efficiency of a frequency band by enhancing the flexibility of the allocation control of a frequency channel to each cell. H Kozue,浜元 こずえ,Y Hitoshi,... 被引量: 0...
PURPOSE: A mobile communications system of an OFDM connecting method and adaptive pilot subcarrier assigning method thereof are provided to reduce an interference effect of the pilot subcarrier between base stations in the mobile communication system by deciding a location of the pilot subcarrier for...
Resource Allocation and Organizational Form We show that establishing truthful upward communication raises the cost of inducing managerial effort compared with stand-alone firms; this effect dominates a... G Friebel,rnMichael Raith - 《American Economic Journal》 被引量: 135发表: 2010年 A Parent's...
