摘要:
A base station allocates a radio resource to a scheduling-target user based on a scheduling metric which is calculated for each of scheduling-target users and calculates the amount of available data for each user. When the radio resource is allocated to the scheduling-target user, the amount of data (Dassign) to be communicated using the allocated radio resource is subtracted from the amount of available data (Davailable) for the user. The amount of available data (Davailable) for each user within a cell is updated (min((Davailable+Dref), Dref)) to be less than or equal to a reference data amount in each control period (TAMBR). The scheduling-target user is selected based on the amount of available data for each user.
摘要:
The base station includes a scheduler controller that controls scheduling operations of a downlink and an uplink. The scheduler controller controls the scheduling operation of the DL and the UL in accordance with a first criterion such that a subframe of user equipment which includes UL data starts, prior to termination of a subframe of base station not including DL data, a second criterion such that the subframe of the user equipment which does not include the UL data starts, prior to the termination of the subframe of the base station including the DL data, or a third criterion such that the subframe of the user equipment which includes a signal other than an ACK/NACK starts, prior to the termination of the subframe of the base station including the DL data.

A mobile station UE of the present invention is a mobile station that communicates with a radio base station using equal to or greater than two carriers, wherein the equal to or greater than two carriers include a first carrier and a second carrier, the mobile station including: a first communicating unit configured to perform communication with the first carrier; and a second carrier measuring unit configured to perform measurement of the second carrier, wherein, in a case where a measurement gap for measuring the second carrier is set, the first communicating unit is configured to perform communication with the first carrier without considering the measurement gap when the second carrier is activated, and not to perform communication with the first carrier in the measurement gap when the second carrier is not activated.
摘要:
A base station apparatus capable of communicating with a user equipment terminal using a downlink shared channel is disclosed. The base station apparatus includes a user selection unit selecting a user equipment terminal to which radio resources are to be allocated, the selection being based on whether there is a MAC-layer control signal to be transmitted to the user equipment terminal.
摘要:
A radio base station includes: a measurement unit which measures a resource use amount in each time frame within predetermined period; a downlink persistent allocation signal transmission unit which transmits to a mobile station, a persistent allocation signal indicating a downlink radio resource allocation start moment; and a downlink communication unit which transmit downlink data using downlink radio resource starting at the downlink radio resource allocation start moment. The downlink persistent allocation signal transmission unit decides the downlink radio resource allocation start moment in accordance with a resource use amount in each time frame.
