Abstract (en)
[origin: WO2020068596A1] Technology is disclosed for a user equipment (UE) operable for low latency random access channel (RACH) communication in a fifth generation (5G) new radio (NR) network. The UE can be configured to 5 : identify one or more physical random access channel (PRACH) resource sets based on a modulation and coding scheme (MCS) or a transport block size (TBS), wherein each of the one or more PRACH resource sets includes one or more physical resources; select randomly a PRACH preamble from the one or more identified PRACH resource sets; encode a message A (msgA), wherein the 10 msgA includes the PRACH preamble in the one or more physical resources from the one or more PRACH resource sets; and encode the msgA, wherein the msgA further includes payload on a physical uplink shared channel (PUSCH) in one or more physical resources associated with the one or more PRACH resource sets in msgA.
