A method of transmitting control information includes dividing frequency bandwidth into ranges to which the same PMI (precoding matrix index) is applied, obtaining multiple antenna information by the range to which the same PMI is applied and transmitting the multiple antenna information. Since multiple antenna information is transmitted by the unit of a range to which the same PMI is applied, radio resources allocated for transmitting the multiple antenna information may be reduced, thereby enhancing data transmission efficiency.

Apparatus, and an associated method, for determining an allowable packet size of data packets communicated by a mobile host to a correspondent host. Path MTU discovery is performed at a network-based proxy on behalf of the mobile host. Once the path MTU is determined, an ICMPTv6 message is sent to the mobile host to inform the mobile host of the allowable packet size.

A method for transmitting a band bitmap in a wireless communication system is provided. The method includes selecting at least one selection band from a plurality of bands, the plurality of bands being distributed throughout a whole frequency band, grouping the plurality of bands into a plurality of band groups, setting a primary bitmap for each band group according to whether the selection band is included in each band group and setting a secondary bitmap for bands in each band group, and transmitting the primary bitmap and the secondary bitmap. Radio resources used to transmit a band bitmap can be reduced by decreasing the number of bits of the band bitmap.

A method for transmitting data for a half-duplex device in a wireless communication system is provided. The half-duplex device receives first downlink control information from a base station in a first subframe. The half-duplex device transmits uplink data to the base station in a second subframe. The first downlink control information includes a resource through which the uplink data is transmitted and information on the second subframe.

A radio communication method is provided for reducing the overhead of radio resources (transmission power, transmission time, frequency band) caused by the transmission of a control signal to a mobile station in a poor propagation environment and thus enabling an improvement of throughput of the entire system. A base station (101) and mobile stations (111 and 112) are connected to allow communication by way of radio links in which a control channel and data channel can be set on each of downlinks and uplinks. The base station (101) uses the control channel to transmit a control signal to the mobile stations (111 and 112). The mobile stations (111 and 112), based on the control signal received from the base station (101), use a data channel to transmit or receive data. The base station (101) alters the amount of information of the control signal in accordance with communication conditions of the propagation paths of the radio links formed with the mobile stations (111 and 112).

A femto cell device comprises: a receiver for receiving transmissions from a user terminal in an active call with a macro cellular network node; an analyzer for determining a radio frequency (RF) signature characterizing the transmissions received from the user terminal; an authorizer arranged to use the RF signature to determine if the user terminal is authorized to use the femto cell device; and a communicator for informing the core network that the femto cell device is a valid candidate handover target for the user terminal when the user terminal is determined by the authorizer to be authorized to use the femto cell device.

A base station comprises a radio communication unit that uses a radio resource to perform radio communication with a radio terminal; an inter-base station communication unit that performs inter-base station communication with another base station; and a control unit that controls the radio communication unit and the inter-base station communication unit. The inter-base station communication unit comprises a transmission unit that transmits interference control information for controlling interference with the other base station, to the other base station; and a reception unit that receives information indicating a usage of the radio resource in the other base station, from the other base station. The control unit acquires the usage of the radio resource in the radio communication unit and changes a transmission cycle of the interference control information in accordance with at least one of the usage of the radio resource in the radio communication unit and the usage of the radio resource in the other base station.

Various examples provide a method for radio resources management. An MCE or a GCSE AS or a UE receives usage information of eMBMS radio resources, and adjusts radio resources in response to a determination that there is an overload state. The MCE may re-configure the eMBMS radio resources. Alternatively, the UE or the GCSE AS may establish a unicast channel for transporting a GCSE service which was transmitted on an overloaded eMBMS bearer, and release the eMBMS bearer. The technical mechanism can make effective use of radio interface resources and reduce data loss.

The present invention relates to an apparatus and method for arbitrating radio resources between femto base stations in which, when handover of a terminal takes place between femto base stations, the handover is carried out by reallocating radio resources of a serving femto base station assigned to the terminal to a target femto base station, to rearbitrate the radio resources and reduce the time required for rearbitration, thereby enhancing communication effectiveness.

A communication control method includes the step of restricting the number of communication channels used dedicatedly by each of mobile stations or a resource of communication channels used dedicatedly by each of the mobile stations when both communication channel shared by the mobile stations and communication channels used dedicatedly by each of the mobile stations are simultaneously used in a mobile communication system.

A telecommunication method for a user equipment roaming to a visited network is provided. A local network provides a telecommunication service to a user corresponding to the user equipment. In the telecommunication method, a service is started on the user equipment. According to the started service, the user equipment transmits an access point name query to the visited network. According to the access point name query, the visited network performs an authority check procedure with the local network on the user. When the user passes the authority check procedure, the visited network delivers an access point name corresponding to the service to the user equipment and the user equipment starts the service through the access point name.
