Timing determination techniques for 5g radio access network cells

An apparatus, comprising:

• a memory interface;
• and
• circuitry for user equipment (UE), the circuitry to:
• detect downlink control information (DCI) scheduling a downlink (DL) data transmission of a next generation node B (gNB) during a random access procedure in a next generation radio access network (NG-RAN) cell;
• identify an applicable slot offset value for the DL data transmission;
• identify a scheduled slot for the DL data transmission based on:
• a slot of receipt of the DCI;
• and
• the applicable slot offset value;
• and
• access a DL wireless channel of the NG-RAN cell during the scheduled slot to receive the DL data transmission.

User equipment (UE), comprising:

• radio frequency (RF) circuitry;
• and
• baseband circuitry coupled to the RF circuitry, the baseband circuitry to:
• detect receipt, from a next generation node B (gNB), of a grant of resources for an uplink (UL) data transmission during a random access procedure in a next generation radio access network (NG-RAN) cell;
• identify a scheduled slot for the UL data transmission based on a slot of receipt of the grant and an applicable slot offset value;
• and
• encode data comprising a radio resource control (RRC) message for transmission over a physical uplink shared channel (PUSCH) of the NG-RAN cell during the scheduled slot.

At least one non-transitory computer-readable storage medium having stored thereon instructions that, when executed by processing circuitry of user equipment (UE), cause the UE to:

• transmit a random access preamble to initiate a random access procedure in a next generation radio access network (NG-RAN) cell;
• detect downlink control information (DCI) scheduling a data transmission over a wireless channel of the NG-RAN cell during the random access procedure;
• identify a scheduled slot for the data transmission based on a slot of receipt of the DCI and a slot offset value applicable to the data transmission;
• and
• access the wireless channel during the scheduled slot.
