Abstract: A wireless device transmits, to a base station, at least one first measurement report of at least one synchronization signal of a cell. An indication, of one or more channel state information reference signals (CSI-RSs) of the cell, is received from the base station 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. Based on the indication, at least one second measurement report of the one or more CSI-RSs is transmitted. Based on the at least one second measurement report, a downlink control information is received that initiates a random access procedure of the cell based on at least one first CSI-RS from the one or more CSI-RSs.

Abstract: This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with a Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.
