Wireless communication system, method for controlling wireless communication system, base station, and mobile station

摘要

Provided is, in wireless communication systems such as TD-LTE where there might be difference in frequency band allocated to a mobile station between uplink and downlink, a wireless communication system which is capable of ensuring desired antenna directivity by the mobile station controlling an adaptive array antenna, such a method for controlling a wireless communication system, such a base station, and such a mobile station. The mobile station transmits to the base station a message indicating that the self station includes an adaptive array antenna. Upon receiving the message, the base station assigns a downlink resource block and an uplink resource block following the downlink resource block allocated to the mobile station within the same frequency band. The mobile station 1 controls the adaptive array antenna based on a signal received using the allocated downlink resource block and transmits a signal using the allocated uplink resource block.

1. A method for controlling a wireless communication system which includes a mobile station and a base station and in which there might be a difference in a frequency band between a downlink resource and an uplink resource allocated to the mobile station, the mobile station including an adaptive array antenna, the method comprising:
the step, performed by the mobile station, of transmitting to the base station a message indicating that the mobile station includes the adaptive array antenna; the step, performed by the base station in response to receiving the message, of assigning the same frequency band as a frequency band of a downlink resource block to be a frequency band of an uplink resource block following the downlink resource block, the downlink resource block and the uplink resource block being allocated to the mobile station; and the step, performed by the mobile station, of controlling directivity of the adaptive array antenna based on a signal received by using the allocated downlink resource block and transmitting a signal by using the allocated uplink resource block.
