One or more channel state information reference signals (CSI-RSs) of the cell are selected based on: the at least one first measurement report; and a first antenna port of the one or more CSI-RSs being quasi-collocated with a second port of the at least one synchronization signal. At least one second measurement report of the one or more CSI-RSs is received. At least one first CSI-RS of the one or more CSI-RSs is selected based on the at least one second measurement report. A downlink control information initiating a random access procedure of the cell is transmitted. The random access procedure is based on the at least one first CSI-RS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Selecting a CSI-RS for a random access procedure of a cell","description":"A base station receives, from a wireless device, at least one first measurement report of at least one synchronization signal of a cell.
