    摘要: The invention relates to a communications system comprising a transmitter (30) and a receiver (30) for transmitting transparent data over a connection (32) therebetween. The bandwidth (b2) assigned to the connection (32) is wider than the bandwidth (b1) actually required by a nominal bit rate of the transparent data so as to allow the use of a retransmitting protocol over the connection by enabling data transmission to stop and wait for retransmission of the incorrectly received frames while a transparent connection with a constant delay and a constant bit rate and a low BER is provided to the user. The incoming transparent data stream with a constant bit rate is buffered into a transmission buffer (300) and the frames received over the retransmitting connection (32) are buffered into a receiving buffer (310) which outputs the transparent data at the constant nominal bit rate.

    摘要: A communication system, a mobile services switching center and a method is described, for allowing a multi-dialogue communication to take place between a first subscriber station (MS1, MS2, ...MSn) and a second subscriber station (ISDN ST1) through a mobile services switching center (MSC/VLR) of a public land mobile network (PLMN). A mapping means (MP) of the mobile services switching center (MSC) maps several communication channels between the first subscriber station (MS1, MS2, ...MSn) and the mobile services switching center (MSC/VLR) onto at least one second communication channel (CC2) between the PLMN and a fixed network (FN).

    摘要: A communication device sets a first channel access timer to a first duration in which at least a first portion of a communication channel is expected to be busy, the first timer corresponding to a first one of a plurality of component channels of the communication channel. The communication device also sets a second channel access timer to a second duration in which at least a second portion of the communication channel is expected to be busy, the second timer corresponding to a second one of the plurality of component channels. The communication device counts down the first timer and the second timer. When at least one of the first timer and the second timer reaches zero, the communication device determines whether one or more of the component channels are idle, and transmits at least one signal in at least one of the component channels determined to be idle.

    摘要: 【課題】通信経路の帯域が大きく変動する場合に、映像データの配信レートを高速に変更して、映像を安定して再生することができるようにする。 【解決手段】端末装置が、映像配信装置に蓄積されたセグメントの構成内容に関するセグメント構成情報を参照して、映像配信装置に要求するセグメントとして、帯域関連情報(例えば接続先の無線通信方式に関する接続先情報)に基づいて、帯域が広い状態と判定されると、時間長が短いセグメントを選択し、帯域が狭い状態と判定されると、時間長が長いセグメントを選択して、映像配信装置にセグメント取得要求を送信する。映像配信装置が、端末装置から送信されるセグメント取得要求を受信すると、そのセグメント取得要求に対応する配信レートおよび時間長のセグメントを端末装置に送信し、端末装置が、映像配信装置から送信されるセグメントを受信する。

    摘要: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to determine an RU allocated to the apparatus within a communication bandwidth for OFDMA transmission. The apparatus is configured to transmit a data packet on the allocated RU based on requirements associated with an amount of inter-RU interference to other RUs allocated to other wireless devices. In an aspect, the requirements may include at least one of an error vector magnitude (EVM) requirement or a spectral mask requirement.
