Additional reference signals may be allocated or assigned to various resource elements (REs) of a transmission time interval (TTI). The receiving device (e.g., a base station or a user equipment (UE)) may be configured to use the additional reference signals during channel estimation. The use of additional reference signals may improve the accuracy of the channel estimations. In downlink communications, a base station may allocate one or more channel state information reference signals (CSI-RSs) to a port of a UE. In uplink communications, a UE may transmit several sounding reference signals (SRSs) in a group."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques for channel estimation","description":"Techniques are described herein for performing channel estimation for both uplink and downlink channels.
