FLEXIBLE CONFIGURATION OF UPLINK AND DOWNLINK RATIO BY EXCHANGING INFORMATION USING AN X2 INTERFACE

摘要

An apparatus and method for the flexible configuration of uplink and downlink ratio by exchanging information relating to user traffic pattern among eNodeBs in a wireless communications network using the X2 interface is disclosed herein. In one embodiment, the information exchanged among the eNodeBs comprises downlink subframe transmission power information and uplink subframe reception power information. In another embodiment, the information exchanged among the eNodeBs comprises downlink subframe loading information and uplink subframe loading information. The exchange of such information facilitates implementation of a flexible or dynamic configuration of the uplink and downlink ratio.

主权项

1. A first base station for exchanging traffic information to dynamically adjust a downlink and uplink configuration, the first base station comprising:
a transceiver; and a processor in communication with the transceiver, the processor configured to:
determine a downlink subframe traffic volume for each downlink subframe within a reporting period,determine an uplink subframe traffic volume for each uplink subframe within the reporting period, andprepare a downlink subframe traffic information corresponding to the downlink subframe traffic volume and an uplink subframe traffic information corresponding to the uplink subframe traffic volume for the reporting period for transmission to a second base station.
