Method for radio resource control

In order to control the use of physical radio resources, the physical radio resources are divided into chronologically consecutive frames (14), so that a frame contains slots (16, 17, 18) of various sizes, which slots represent a given share of the physical radio resources contained in the frame and can be individually allocated to different radio connections. The first dimension of a frame is time and the second dimension can be time, frequency or code. In the direction of the second dimension the slots represent various sizes, and a given first integral number of slots of the first size can be modularly replaced by another integral number of slots of another size. A certain number of consecutive frames form a superframe (19), in which case frames with corresponding locations in consecutive superframes are equal in slot division and allocations, if the data transmission demands do not change. Changes in the state of occupancy of the slots are possible at each superframe. In order to form an uplink connection, the mobile station sends a capacity request, where it indicates the type of requested connection and the demand of resources. In order to form a downlink connection, the base station subsystem sends a paging call, where it indicates the location in the superframe of the slots allocated to the connection. In order to indicate the state of occupancy, the base station subsystem maintains a superframe-size parametrized reservation table.

Device-to-device group communication method and device using the same

Provided are a device-to-device (D2D) group communication method and a device using the same. The method includes transmitting a scheduling request for D2D group communication to a base station, receiving first radio resource information for a status report of D2D data to be transmitted from the base station, transmitting a D2D buffer status report to the base station through a first radio resource, receiving second radio resource information including D2D resource allocation information necessary for the D2D group communication from the base station, and transmitting control information for the D2D group communication including a D2D group identifier (ID) as a device ID and D2D user data to two or more communication partner devices belonging to the D2D group.

Remotely Reconfigurable Distributed Antenna System and Methods

The present disclosure is a novel utility of a software defined radio (SDR) based Distributed Antenna System (DAS) that is field reconfigurable and support multi-modulation schemes (modulation-independent), multi-carriers, multi-frequency bands and multi-channels. The present disclosure enables a high degree of flexibility to manage, control, enhance, facilitate the usage and performance of a distributed wireless network such as flexible simulcast, automatic traffic load-balancing, network and radio resource optimization, network calibration, autonomous / assisted commissioning, carrier pooling, automatic frequency selection, frequency carrier placement, traffic monitoring, traffic tagging, pilot beacon, etc. As a result, the SDR DAS can increase the efficiency and traffic capacity of the operators' wireless network.

Method of partitioning resources in a cognitive radio wireless communication system and system supporting the same

A method of partitioning resources in a CR wireless communication system and a system supporting the same are provided. A new BS receives radio resource status information from a prior BS using a particular frequency band, and requests resource partitioning to the prior BS using a new uplink subchannel defined for communications between BSs. Resource negotiation messages are exchanged over a channel defined between the two BSs so as to efficiently partition resources between the BSs.

Power- and bandwidth-adaptive in-home wireless communications system with power-grid-powered agents and battery-powered clients

A radio link management system for a home or office substantially (i) an ad hoc network of agents wirelessly communicating among themselves, while (iii) clients wirelessly communicate with proximate agents. Control of the network may be centralized as network controller integrated with an agent, or may be distributed upon the network of agents. Some agent or agents, which may include an agent that is also the network controller, typically serves as a gateway device which connects to a worldwide communications network external to the home or office, normally by fiber or by wire.Each agent is most commonly a small radio transceiver plus logic and power supply that mounts upon a wall and plugs directly into an AC power socket. Agents wirelessly communicate among themselves and with the controller-which may be centralized or distributed-in a bandwidth-efficient mode since prime power is not an issue. Each client, which is most commonly a battery-powered user device, wirelessly radio communicates with one or more proximately-located agents. Consistent with overall demand for the radio resource, parameters for radio communication are allocated ad hoc in a manner which is (a) client-dependent, and which (b) uses the least power from the battery-powered client. The agents establish an ad-hoc network among themselves, with routing among and between the agents being both multi-hop and "minimum hop" to conserve bandwidth. Accordingly both power and bandwidth are conserved, each as and where required and desired.

Method of transmitting ack/nack signal in wireless communication system

A method of transmitting an acknowledgement (ACK) / non-acknowledgement (NACK) signal in a wireless communication system is provided. The method includes: allocating a radio resource; and transmitting the ACK / NACK signal through an ACK channel in a location determined by an index for the radio resource, wherein the radio resource includes at least one resource unit which is a basic unit for resource allocation, the resource unit is at least one of a localized resource unit including subcarriers contiguous in a frequency domain and a distributed resource unit including subcarriers distributed in the frequency domain, an index of the localized resource unit is directly mapped to an index of the ACK channel, and an index of the distributed resource unit is mapped to an index of the ACK channel according to a permutation rule.
