MULTIPLEXING RANDOM ACCESS TRANSMISSIONS WITH DIFFERENT SPATIAL FILTERS

Abstract: methods, systems, and devices for wireless communication are described. in some systems, a first network node may transmit a first synchronization signal block (ssb) associated with a first spatial filter and a first set of random access occasions within a respective instance of a random access occasion window and a second ssb associated with a second spatial filter and a second set of random access occasions that overlap in time with the first set of random access occasions during the random access occasion window. a second network node may receive the ssbs and transmit instances of a random access message during one or more instances of the random access occasion window using the first spatial filter, the second spatial filter, or both based on a rule for random access message multiplexing when random access occasions associated with different spatial filters to be used for random access messages overlap in time.
