  • Patent number: 9730221
    Abstract: A mobile station (MS) performs a first random access procedure using a dedicated preamble for non-contention based random access on a first available random access channel (RACH) of a plurality of RACHs in time domain within a period that the dedicated preamble is valid. In addition, the MS performs a second random access procedure using the dedicated preamble for non-contention based random access on the first available RACH after the predetermined time window has expired in a case that a random access response to the transmitted preamble is not received within a predetermined time window monitoring for the random access response. The MS also transmits the dedicated preamble on a RACH allowed to transmit by the BS, where any one of the RACHs in frequency domain is allowed to be transmitted by the BS over a period of time that the plurality of RACHs are allocated to a single carrier.

  • Patent number: 8743821
    Abstract: A radio communication system includes a base station device and a plurality of mobile station devices which radio-communicate with the base station device. The base station device allocates random access signal identifiers for identifying random access signals to the mobile station devices and decides an allocation period for each of the random access signal identifiers used by the mobile base stations. During the allocation period, each of the mobile station devices transmits a random access signal corresponding to the allocated random access signal identifier. Thus, it is possible to suppress a delay until the random access procedure using a dedicated preamble is complete.

  • Publication number: 20110038299
    Abstract: Efficient use of an identification information group (MAC ID) region which is assigned to a mobile station apparatus by a base station apparatus, and reduction in an uplink resource for making a request from the mobile station apparatus to the base station apparatus to start transmission of an MBMS service, are realized. In a mobile communication system which provides a Multimedia Broadcast Multicast Service (MBMS), a mobile station apparatus communicates with a base station apparatus. A control unit 210 is included which performs mapping between an MBMS service ID for identifying the MBMS service provided in this mobile communication system, and an MBMS short transmission ID for identifying the MBMS service transmitted within a cell, and further maps the MBMS short transmission ID to an MBMS group ID (MBMS-RNTI) for identifying a group of mobile stations to which multicast is performed.

  • Publication number: 20070274727
    Abstract: A communications system implementing high-speed, high-quality communication in an oblong communication range such as mobile communication, and a leaky optical fiber preferably used in such communications system are provided. An optical fiber (2) is a GI-type optical fiber having a core structured such that the refractive index at the center is large, gradually decreasing as it approaches the periphery, and may have scatterers mixed therein. When modulated light enters the optical fiber (2) from a transmitter (1), the modulated light proceeds through the optical fiber (2) while a part of the light leaks from the side thereof. A receiver (3) receives this leaked light, and demodulates it so as to obtain data. Since the optical fiber (2) is a GI type, high-speed, high-quality mobile communication is possible with little waveform deformation.
