|1. (WO2017151187) LOW LATENCY PRACH DESIGN IN UNLICENSED SPECTRUM|
|Applicants:||INTEL IP CORPORATION

|Title:||LOW LATENCY PRACH DESIGN IN UNLICENSED SPECTRUM|
Methods for low latency PRACH design in unlicensed spectrum are generally described herein. An exemplary apparatus of User Equipment (UE) includes memory; and processing circuitry, the processing circuitry to perform a listen-before-talk (LBT) procedure on one or more channels of an unlicensed spectrum. The processing circuitry further to, in response to a clear channel assessment (CCA), encode a first message for a first transmission associated with a low latency random access (RA) procedure on the unlicensed spectrum. The first message includes a physical random-access channel (PRACH) preamble and a message part. The message part includes at least one of a cell radio network temporary identifier (C-RNTI), buffer status report (BSR) information, capability of the UE, and/or an identity of the UE. The processing circuitry further to, in response to receipt of an uplink (UL) grant based on the first step of low-latency RA procedure, encode UL data for transmission.
