Method for supporting flexible frame structures in wireless communication systems

摘要

A wireless communication base station is disclosed, configured to serve a plurality of user terminals in a series of downlink radio frames wherein user terminals in a first group are served in a first temporal region of the downlink radio frame and user terminals in a second group are served in the second temporal region of the downlink radio frame. A downlink radio frame contains an indicator signaling a change of duration of either of the first or second temporal region of at least one downlink radio frame in a series of downlink radio frames.

1. A method in a wireless communication base station, the method comprising:
serving a plurality of user terminals in a series of downlink radio frames, the plurality of user terminals assigned to first and second groups; each downlink radio frame having a first temporal region and a second temporal region, the user terminals in the first group served in the first temporal region of the downlink radio frame and the user terminals in the second group served in the second temporal region of the downlink radio frame; changing a duration of either the first temporal region or the second temporal region of at least one downlink radio frame in the series of downlink radio frames in response to a grouping criteria adjustment representing a changed characteristic of at least one of the first group of user terminals and the second group of user terminal; including, in a downlink radio frame, an indicator signaling a change of duration of either the first temporal region or the second temporal region of at least one downlink radio frame in the series of downlink radio frames.
