Abstract
Systems and methods are described for a 2-Step Random Access Channel (RACH) for New Radio (NR) with unlicensed operation. The systems and methods include at least, generating, by a user equipment (UE), a MsgA of a random access channel (RACH) procedure associated with the NR network, the MsgA having a physical random access channel (PRACH) occasion and an associated physical uplink shared channel (PUSCH) occasion for transmission during the RACH procedure, and transmitting, by the UE, the MsgA to a base station (gNB) over unlicensed spectrum of the NR network during the RACH procedure.
Claims20
A method of operating a user equipment (UE) in a wireless network comprising:
- generating, by the UE, a MsgA of a random access channel (RACH) procedure associated with the wireless network, the MsgA having a physical random access channel (PRACH) occasion and an associated physical uplink shared channel (PUSCH) occasion for transmission during the RACH procedure;
- and
- transmitting, by the UE, the MsgA to a base station (BS) over unlicensed spectrum of the wireless network during the RACH procedure.
A non-transitory computer readable medium having instructions stored thereon that, when executed by a user equipment (UE), cause the UE to perform operations comprising:
- generating a MsgA of a random access channel (RACH) procedure associated with a wireless network, the MsgA having a physical random access channel (PRACH) occasion and an associated physical uplink shared channel (PUSCH) occasion for transmission during the RACH procedure;
- and
- transmitting the MsgA to a base station (BS) over unlicensed spectrum of a wireless network during the RACH procedure.
A user equipment (UE) comprising:
- processor circuitry configured to generate a MsgA for a random access channel (RACH) procedure, the MsgA having a physical random access channel (PRACH) occasion and an associated physical uplink shared channel (PUSCH) occasion for transmission during the RACH procedure;
- and
- radio front end circuitry, coupled to the processor circuitry, configured to transmit the MsgA over unlicensed spectrum of a wireless network during the RACH procedure, wherein the PRACH occasion and the associated PUSCH occasion are configured to cause the MsgA to satisfy an occupied channel bandwidth (OCB) requirement of the unlicensed spectrum during the RACH procedure.
