Abstract  Abstract

Transitioning from basic higher order MIMO estimation to enhanced higher order MIMO estimation (and vice-versa) can be accomplished through the signaling of high-speed downlink packet access (HSDPA) shared control channel (HS-SCCH) orders to next-generation user equipments (UEs). A base station can be configured to send an HS-SCCH order indicating activation of scheduled pilot channels and then begin transmitting the scheduled pilot channels after receiving an ACK message from at least one next-generation UE. A base station can also be configured to send an HS-SCCH order indicating de-activation of scheduled pilot channels to next-generation UEs scheduled for downlink transmission and then stop transmitting the scheduled pilot channels after receiving ACK messages from each next-generation UE. Alternatively scheduled pilot channels may be activated/de-activated upon expiration of a timeout period even without receiving an ACK message from some or all of the next-generation UEs scheduled for downlink transmission.
