Abstract
Disclosed are systems and methods for coverage-based robust and efficient random access for 5G networks which uses a higher Aggregation Level (AL) and lower and Modulation and Coding Scheme (MCS) the larger the Path Loss (PL) between the user equipment (UE) and the base station. To do so, the message preamble of the Random Access Channel (RACH) message received from the UE by the base station (gNB) is associated with the PL between the base station and the UE, and is thus used to determine the AL and MCS.

A method comprising:
- receiving, by a Next Generation Node B (gNB) in a fifth generation (5G) New radio (NR) wireless network, a random access channel (RACH) message preamble from a user equipment device (UE) on the 5G NR network;
- determining, by the gNB, which preamble type the message preamble is;
- determining, by the gNB, an Aggregation Level (AL) and a Modulation and Coding Scheme (MCS) to use for the UE and gNB to exchange subsequent messages during a RACH phase based on which preamble type the message preamble is;
- and
- the gNB communicating during the RACH phase with the UE using the determined AL and MCS;
- wherein the determining the AL and the MCS to use includes:
- determining, based on which preamble type the message preamble is, an estimated Path Loss (PL) between the UE and the gNB;
- and
- determining, by the gNB, the AL and the MCS to use for the UE and gNB to exchange subsequent messages during the RACH phase based on the estimated PL between the UE and the gNB determined according to the preamble type.
A system comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the system to perform operations including:
- receiving, by a Next Generation Node B (gNB) in a fifth generation (5G) New radio (NR) wireless network, a random access channel (RACH) message preamble from a user equipment device (UE) on the 5G NR network;
- determining, by the gNB, which preamble type the message preamble is;
- determining, by the gNB, an Aggregation Level (AL) and a Modulation and Coding Scheme (MCS) to use for the UE and gNB to exchange subsequent messages during a RACH phase based on which preamble type the message preamble is;
- and
- the gNB communicating during the RACH phase with the UE using the determined AL and MCS;
- wherein the determining the AL and the MCS to use includes:
- determining, based on which preamble type the message preamble is, an estimated Path Loss (PL) between the UE and the gNB;
- and
- determining, by the gNB, the AL and the MCS to use for the UE and gNB to exchange subsequent messages during the RACH phase based on the estimated PL between the UE and the gNB determined according to the preamble type.
A non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, when executed by at least one processor, cause a system to perform operations including:
- receiving, by a Next Generation Node B (gNB) in a fifth generation (5G) New radio (NR) wireless network, a random access channel (RACH) message preamble from a user equipment device (UE) on the 5G NR network;
- determining, by the gNB, which preamble type the message preamble is;
- determining, by the gNB, an Aggregation Level (AL) and a Modulation and Coding Scheme (MCS) to use for the UE and gNB to exchange subsequent messages during a RACH phase based on which preamble type the message preamble is;
- and
- the gNB communicating via the RACH with the UE using the determined AL and MCS;
- wherein the determining the AL and the MCS to use includes:
- determining, based on which preamble type the message preamble is, an estimated Path Loss (PL) between the UE and the gNB;
- and
- determining, by the gNB, the AL and the MCS to use for the UE and gNB to exchange subsequent messages during the RACH phase based on the estimated PL between the UE and the gNB determined according to the preamble type.
