摘要: Systems and methodologies are described that facilitate providing time-division duplexed beam-forming support in traditionally non-time-division wireless systems, such as an OFDMA system, a WCDMA etc. According to aspect, base station can analyze pilot information, portion of bandwidth over which user device is transmitting, transmit on the downlink using pre-hopped utilized by preceding reverse link time slot. The additionally segment reassignments hopping between devices served station. Additionally, instruct provide on-demand information resolve ambiguity related thereto.
