Radio communication system, base station, mobile station, and radio communication method

摘要

A radio communication system includes a base station and a mobile station communicating with the base station. The base station includes a selection unit and a first transmitting unit. The selection unit selects an item of identification information for identifying a data series from a plurality of data series corresponding to resources used to transmit a signal that the mobile station uses to measure reception quality. The first transmitting unit transmits the item of identification information. The mobile station includes a receiving unit, a measurement unit, and a second transmitting unit. The receiving unit receives the item of identification information that the first transmitting unit has transmitted. The measurement unit measures the reception quality using a signal of the data series identified by the item of identification information. The second transmitting unit transmits information indicating the reception quality that the measurement unit has measured to the base station.

主权项

1. A radio communication system comprising a base station and a mobile station communicating with the base station, wherein
the base station includes: a processor configured to: select identification information for identifying a data series corresponding to a position of the mobile station from a plurality of data series corresponding to resources used to transmit a signal that the mobile station uses to measure reception quality, the identification information indicating a correspondence between one or more antenna ports and a parameter for specifying the data series, wherein the parameter for specifying the data series changes the data series based on the corresponding position of the mobile station; and a transmitter configured to transmit the identification information to the mobile station, and the mobile station includes: a receiver configured to receive the identification information transmitted by the base station; a processor configured to measure the reception quality at the one or more antenna ports using the signal of the data series identified by the identification information; and a transmitter configured to transmit, to the base station, information indicating the reception quality at the one or more antenna ports, wherein the base station processor is further configured to prepare a plurality of sequence numbers of the signal for respective antenna ports and provide the data series to be used by the mobile station to measure the reception quality.
