Description

Method and equipment for dynamically scheduling UE (user equipment), base station
Technical Field
The present invention relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus used for dynamic scheduling.
Background
Large scale (Massive) MIMO (Multiple Input Multiple Output) becomes a research hotspot of next generation mobile communication. In large-scale MIMO, multiple antennas form a narrow beam pointing to a specific direction by beamforming to improve communication quality. Both data channels and control channels can be used to improve transmission quality through multi-antenna beamforming.
In conventional LTE (Long Term Evolution) and LTE-a (Long Term Evolution Advanced, enhanced Long Term Evolution) systems, a physical layer Control channel corresponding to dci (downlink Control information) is transmitted in a non-beamforming manner. Hybrid beamforming, both analog beamforming and digital beamforming, has been discussed in 3GPP (3rd Generation Partner Project) RAN1(Radio Access Network) and has been considered as an important research direction in NR (New Radio) systems. Since analog beamforming is a wideband operation, control channels using different analog beamforming vectors can only be transmitted in a TDM (Time Domain Multiplex) manner, and accordingly new control channel designs need to be considered.
Disclosure of Invention
In the 5G system, one implementation is that the UE blindly detects the control signaling only in a time window corresponding to one beamforming vector, however, because the direction of the beamforming vector of the base station is inconsistent with the assumed direction of the UE and other unpredictable interference, blindly detecting only in a corresponding time window brings a risk of losing the control signaling. Another implementation manner is that the UE blindly detects the control signaling in the time windows corresponding to all beamforming vectors, which may cause the problems of higher complexity and more complex implementation.
The present invention provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict. For example, embodiments and features in embodiments in the UE of the present application may be applied in a base station and vice versa.
