Intelligent Dynamic Channel Assignment with Small-Cells for Uplink Machine-Type Communications

چکیده
This letter proposes a novel intelligent dynamic channel assignment (DCA) scheme with small-cells to improve the system performance for uplink machine-type communications (MTC) based on OFDMA-FDD. Outdoor MTC devices (OMDs) have serious interference from indoor (IMDs) served by small-cell access points (SAPs) frequency reuse. Thus, in proposed DCA scheme, macro base station (MBS) first measures received signal strength both OMDs and IMDs after setting transmission power. Then, MBS dynamically assigns subchannels each SAP consideration of strong MBS. Through simulation results, it is shown that outperforms other schemes terms capacity IMDs.

Two-stage dynamic uplink channel and slot assignment for GPRS
General Packet Radio Service (GPRS) uses a two-stage mechanism to allocate uplink radio resource to Mobile Stations (MSs). In stage-1, the Base Station (BS) assigns several Packet Data CHannels (PDCHs) to an MS. Furthermore, a PDCH may be assigned to multiple MSs. In stage-2, therefore, the BS selects one of the multiplexed MSs in a PDCH to use the radio resource. In this work, maintaining a lo...
متن کاملFast Uplink Grant for Machine Type Communications: Challenges and Opportunities
The notion of a fast uplink grant is emerging as a promising solution for enabling massive machine type communications (MTCs) in the Internet of Things over cellular networks. By using the fast uplink grant, machine type devices (MTD) will no longer require random access (RA) channels to send scheduling requests. Instead, uplink resources can be actively allocated to MTDs by the base station. I...
متن کاملDynamic channel assignment in mobile communications based on genetic algorithms
The dynamic channel assignment (DCA) in mobile communications systems using genetic algorithm (GA) is investigated in this research. Two new strategies using GA are proposed. In the first one, the channels previously assigned are kept locked during the call holding time (GAL). In the second one, the calls can be switched to different channels during the connection time (GAS). The performance of...
متن کاملAlgorithms for Dynamic Channel Assignment
The eeciency of channel assignment in a cellular telephone system is considered using the measures of successful channel assignment ratio as well as response time. Existing paradigms of mutual exclusion and dining philosophers from distributed systems are used to synthesize new algorithms that optimize both measures. The results are veriied by extensive simulations.
