摘要:
An eNB1-1 employs frequency hopping that assigns a radio resource to a UE2-1 in response to switching of a frequency of an SRS from the UE2-1, and determines an MCS in a first radio resource block when a first downlink radio resource block is assigned to the UE2-1, on the basis of SINR acquired for a second downlink radio resource block having a frequency bandwidth equal to a frequency bandwidth of the first downlink radio resource and being assigned to the UE2-1 in the past.

A transmission path state estimation unit estimates a state of a transmission path to a wireless terminal based on a DRS (Demodulation Reference Signal) included in uplink user data received from the wireless terminal when a re-sending request is received after transmission of an SRS is stopped. A transmission unit forms directivity of a plurality of antennas based on the estimated state of the transmission path and transmits downlink user data.

If the frequency band of an SRS from a serving radio terminal (UE 2-1) is identical with the frequency band of an SRS from a serving radio terminal (UE 2-2), a radio base station (eNB 1-1) transmits, to one of the serving radio terminals (UE 2-1, UE 2-2), an RRC connection reconfiguration message in which transmission halt request information has been set.

Provided is a base station device which communicates to/from a mobile station device supporting a MIMO scheme. A base station device (100) includes: a number-of-spatial-streams identification section (126) for identifying the number of spatial streams to be formed between the base station device and a mobile station device (200); a PRU-to-be-allocated identification section (128) for identifying at least part of a plurality of radio channels (PRUs), as a PRU to be allocated for forming the spatial streams whose number is identified by the number-of-spatial-streams identification section (126); and a message generating section (130) for transmitting, to the mobile station device (200), a single piece of control information which includes information indicating the number of the spatial streams, and information indicating the PRU to be allocated.

The present invention provides a fixing apparatus which effectively prevents a recording medium from coiling around the surface of a fixing member and also prevents damage to the surface of the fixing member, and an image forming apparatus comprising this fixing apparatus. A gap between the tip end of separating means and the fixing member can be managed appropriately, and as a result, the recording medium can be prevented from coiling around the surface of the fixing member. A spacer is mounted near the tip end of a separating claw, and the spacer contacts a protruding portion of a core metal of a fixing roller. Thus, a gap having a predetermined magnitude is formed between the tip end of the separating claw and the peripheral surface of the fixing roller. The gap is maintained by the spacer, and therefore the gap between the fixing roller and the separating claw can be managed appropriately over the long term. Moreover, paper can be prevented from coiling around the surface of the fixing roller by managing the gap appropriately, and since a contact member contacting the surface (fixing surface) of the fixing roller is not provided, the surface of the fixing roller is not damaged.

Provided is a small-sized electrophotographic apparatus for which maintenance such as disposal of a jam of sheets, replacement of consumables including toner, or replacement of components to be periodically replaced can be facilitated.Thus, there is provided a tandem type electrophotographic apparatus using an intermediate transfer belt, in which photosensitive drums are arranged in a vertical one row, the intermediate transfer belt is located on one side of the row of the photosensitive drums, the developing means are located on the other side of the row of the photosensitive drums, a transfer means for transfer a toner image from the intermediate transfer belt onto a recording medium is located above the row of the photosensitive drums, a recording medium conveying path composed of a vertical conveying path (a front opening door) for conveying a recording medium fed from the recording medium supply means, outside of the developing means and substantially in parallel with the intermediate transfer belt, a curved part and a horizontal conveying path for conveying the recording medium up to a transfer means in a substantially horizontal direction, and a fixing means for fixing a toner image transferred onto the recording medium is incorporated in the horizontal conveying path (a top surface opening door), downstream of the transfer means.
摘要:
An image forming apparatus, having imaging units arranged alternately on both sides of a continuous paper web, is characterized by minimized image misregistration and reduced processing cost. In order to prevent possible color misregistration caused by changes in paper feed path length resulting from the eccentricity of each drive roller, the difference in the eccentric phases of the rollers on the front and back surfaces is controlled, thereby minimizing the difference in changes in paper feed path length.
