A mobile communication method according to the present invention includes the steps of; (A) notifying, from a radio base station (eNB) to a mobile station (UE), a first cycle and information on the uplink radio resource; and (B) determining, at the mobile station (UE), a first allocation starting time, receiving a downlink data via a downlink radio resource and transmitting an acknowledgement information via an uplink radio resource at and after the first allocation starting time, when receiving a fixed allocation signal from the radio base station (UE). In the step (B), the uplink radio resource is adjusted by an adjustment signal included in the fixed allocation signal and the acknowledgement information is transmitted via the adjusted uplink radio resource.

A communication control apparatus (30, 10) used in a mobile communication system includes: means (32, 12) that derives a second target communication quality Q2 for TFs other than a reference format from a first target communication quality for the reference format in a plurality of TFs provide for communicating with an upper layer of a physical channel; means (33, 13) that derives a third target communication quality different from the first target communication quality from the first and the second target communication qualities; and means that sets the third target communication quality to be a target value of transmission power control.
摘要:
In a mobile communication method according to the present invention, a mobile station (UE) transmits uplink data to a radio base station by using an uplink radio resource assigned to the mobile station by predetermined scheduling information, in a predetermined cycle. The method includes the steps: (A) notifying, to the mobile station (UE), the predetermined cycle and information on the uplink radio resource; (B) notifying, to the mobile station (UE), the predetermined scheduling information; and (C) transmitting uplink data in the predetermined cycle by using the uplink radio resource assigned by the predetermined scheduling information, the transmission starting at a certain point determined on the basis of the received predetermined scheduling information. In the step (C), the predetermined scheduling information is discarded, when the information on the uplink radio resource and information notified by the predetermined scheduling information are inconsistent with each other.

摘要:
A retransmission control method has a physical control channel transmission step wherein a transmission side apparatus (10) transmits a new data specifier updated upon new packet transmission and a retransmission sequence number indicating whether transmission is the first transmission or retransmission, through a physical control channel related to a physical data channel. The retransmission control method also has a delivery confirmation information transmitting step wherein the receiving side apparatus (10) transmits delivery confirmation information to a packet received through the physical data channel, based on a new data specifier and the retransmission sequence number received through the physical control channel.
摘要:
In a retransmission control method, each of a transmitting-side apparatus and a receiving-side apparatus includes a first layer and a second layer; and first retransmission control processing is performed between the first layer of the transmitting-side apparatus and the first layer of the receiving-side apparatus, and second retransmission control processing is performed between the second layer of the transmitting-side apparatus and the second layer of the receiving-side apparatus; the first layer of the transmitting-side apparatus determines whether or not specific user data is under the second retransmission control processing, when receiving a retransmission request for the specific user data from the first layer of the receiving-side apparatus, during the first retransmission control processing; and the first layer of the transmitting-side apparatus does not retransmit the specific user data, when determining that the specific user data is under the second retransmission control processing.
摘要:
A disclosed base station apparatus includesa resource allocation unit allocating radio resources using a first resource allocation method for dynamically allocating the radio resources and a second resource allocation method for allocating the radio resources at a constant period, whereinwhen a size of data to be transmitted is equal to or greater than a first threshold value, the resource allocation unit allocates the radio resources using the first resource allocation method, otherwise, the resource allocation unit allocates the radio resources using the second resource allocation method, andwhen the size of the data to be transmitted is equal to or greater than a second threshold value, the resource allocation unit allocates radio resources reserved as radio resources to be allocated using the second resource allocation method as radio resources to be allocated using the first resource allocation method.
摘要:
A mobile station is configured to send a base station a buffer status report explicitly indicating that the amount of a transmission signal in a buffer of the mobile station has become zero. This configuration makes it possible to efficiently allocate radio resources of an uplink shared channel and thereby to increase uplink capacity.
