Abstract: Methods, apparatus and systems are described for preamble aggregation in a random access procedure. In one embodiment, a method performed by a wireless communication device for preamble aggregation is disclosed. The method includes: transmitting, to a wireless communication node, a first message comprising a number of copies of a preamble for an access to the wireless communication node, wherein the number is an integer larger than one, and wherein the copies of the preamble are carried by different uplink random access channel (RACH) occasions respectively; and monitoring, within a response time window, for a second message comprising a response to the first message from the wireless communication node, wherein all of the copies of the preamble are transmitted before the response time window expires.

Abstract: Methods, apparatus, and systems for providing Synchronization Signal Block (SSB) mapping schemes are described. The techniques can be implemented in various embodiments to allow the transmission of SSB using higher spectrum frequencies. The techniques also take into account of various Cyclic Prefix (CP) lengths for compatibility concerns. In one example aspect, a wireless communication method is disclosed. The method includes mapping a synchronization signal block to multiple symbols having a first subcarrier spacing and generating a transmission pattern for a first time interval that includes the multiple symbols for the synchronization signal block. The multiple symbols are from a set of non-consecutive candidate symbol groups.
