摘要
Transitioning from basic higher order MIMO channel estimation to enhanced higher order MIMO channel 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 without receiving an ACK message from some or all of the next-generation UEs scheduled for downlink transmission.
