摘要： The present invention relates to a precursor of positron emission tomography (PET) radioactive medical supplies, a preparation method thereof, and an application thereof, and more specifically, to a precursor having a tetravalent organic salt leaving group, a preparation method, and a method for preparing desired PET radioactive medical supplies in a high radiochemical yield within a short preparation time by introducing 18F using the same through a single step. The precursor having a tetravalent organic salt leaving group of the present invention can simplify the known complex multistep preparation of radioactive medical supplies into a single step, can save production costs because an excessive amount of a phase transfer catalyst is not required, facilitates separation of a compound after reaction, and enables rapid reaction velocity. The features are appropriate for the mass production of PET radioactive medical supplies by an automated synthesis system.

摘要： A method and a device for allocating a persistent resource in a mobile communication system are provided. In a broadband mobile communication system such as an IEEE 802.16m system, when allocating a persistent resource, because the terminal may transmit a Hybrid Automatic Repeat reQuest (HARQ) sub packet in a continuous frame without receiving the HARQ feedback from the base station, uplink coverage may be extended. When persistent resource allocation is used in uplink, the base station may transmit an HARQ sub packet without receiving the HARQ feedback during the persistent resource allocation period to improve uplink coverage of an allocated persistent resource.

摘要： A base station for use in a wireless network that communicates with mobile stations according to the IEEE 802.16m standard. The base station transmits unicast data and E-MBS data in the downlink to mobile stations using physical resource units (PRUs) that are partitioned into a plurality of frequency partitions. The base station transmits E-MBS data using a first set of PRUs in at least a first common frequency partition, wherein the first set of PRUs are also used by at least a second base station to transmit E-MBS data. The base station further transmits unicast data using a second set of PRUs, wherein the second set of PRUs are randomized with respect to PRUs used by the at least a second base station to transmit unicast data.

摘要： Methods and apparatus are provided for requesting uplink Bandwidth (BW) over a BW Request (REQ) channel in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system. A BW REQ indicator is transmitted with a BW REQ message over the BW REQ channel from a Mobile Station (MS) to a Base Station (BS) to request an uplink resource for uplink traffic of a delay sensitive service. A grant of the requested uplink resource is received from the BS in accordance with the transmitted BW REQ indicator and the BW REQ message. The uplink traffic is transmitted from the MS to the BS using the granted uplink resource.
