METHOD AND DEVICE FOR INDICATING DEMODULATION REFERENCE SIGNAL CONFIGURATION, METHOD AND DEVICE FOR TRANSMITTING DEMODULATION REFERENCE SIGNAL, AND METHOD AND DEVICE FOR DETECTING CONTROL SIGNALING

摘要

Disclosed are a method and device for indicating demodulation reference signal configuration, a method and device for transmitting a demodulation reference signal, and a method and device for detecting control signaling, comprising: a base station indicating, to a user equipment, a demodulation reference signal port and/or a demodulation reference signal scrambling sequence adopted at the time of transmitting control signaling on a dedicated control channel, or adopting a demodulation reference signal port and/or a demodulation reference signal scrambling sequence according to a preset rule; and the user equipment detecting, according to the demodulation reference signal port and/or the demodulation reference signal scrambling sequence acquired through the indication or the preset rule, the control signaling transmitted on the dedicated control channel. The present invention may support multiple users to multiplex the same dedicated control channel, and increase the capacity of the control channel.
