    摘要： The present invention provides a surface emitting laser and a photodiode which permit secure mounting even in mounting by flip chip bonding, and high-speed modulation. The present invention also provides a manufacturing method therefor and an optoelectric integrated circuit using the surface emitting laser and the photodiode. Semiconductor stacked layers stacked on a semiconductor substrate have a light emitting portion and a reinforcing portion formed with a recessed portion provided therebetween, and a p-type ohmic electrode and an n-type ohmic electrode are formed on the top of the reinforcing portion. The p-type ohmic electrode is electrically connected to a p-type contact layer through a contact hole vertically formed in polyimide buried in the recessed portion to permit supply of a current to the light emitting portion in the thickness direction. The recessed portion has a groove formed to reach the semiconductor substrate, thereby suppressing the parasitic capacity between the p-type ohmic electrode and the n-type ohmic electrode.

    摘要： In a retransmission-request transmitting method, the receiving side apparatus activates a reordering timer, when receiving a first packet before receiving an unreceived packet with a sequence number smaller than a sequence number of the first packet; triggers transmission of a retransmission request for the unreceived packet, when having not received the unreceived packet by the time of expiration of the reordering timer activated in response to the receipt of the first packet; and stops and reactivates the reordering timer activated in response to the receipt of the first packet, when a value of the sequence number of the first packet falls out of a range of the receiving side window as a result of changing the upper limit value and the lower limit value in accordance with a sequence number of a second packet received from the transmitting side apparatus.

    摘要： A controlling method and a radio base station apparatus capable of variably determining a Transmission Time Interval (TTI) length in accordance with a communication environment of a mobile terminal is disclosed. The radio base station apparatus includes a receiving section receiving information via an uplink channel; and a scheduler variably determining a Transmission Time Interval (TTI) length for any one of an uplink shared channel and a downlink shared channel or both based on at least any of a moving speed of a mobile terminal, location of the mobile terminal in a cell, a provided throughput value, and a number of retransmissions obtained from the received information. Preferably, the scheduler includes a TTI length allocation table describing relationships between parameter values and the corresponding TTI length, the parameters being used for estimating the location and/or the moving speed of the mobile terminal.
