METHOD, APPARATUS AND SYSTEM FOR IMPLEMENTING DOWNLINK BEAM INDEX PROCESSING

摘要

Disclosed are a method, apparatus and system for implementing downlink beam index processing, comprising: notifying, by a base station through a pre-defined manner and/or system information, of using at least one of the following beam indication manners and relevant configuration information to indirectly indicate a downlink beam index required to be fed back when an uplink access signal is sent: using a time domain location of the uplink access signal to indicate a downlink beam index which is fed back; using a frequency domain location of the uplink access signal to indicate the downlink beam index which is fed back; using an uplink access signal sequence to indicate the downlink beam index which is fed back; adding index indication bit information at the end of the uplink access signal so as to indicate the downlink beam index which is fed back; adding a beam identification sequence at the end of the uplink access signal so as to indicate the downlink beam index which is fed back; and the downlink beam index being a beam index corresponding to using a beam to send a downlink signal.
