Abstract: Disclosed are systems and methods for user equipment (UE) transmission adaptation after physical uplink shared channel (PUSCH) misdetection. Instead of the cell base station (e.g., gNB) transmitting a new grant with exactly the same parameters as a first grant transmission that failed to receive a response from the user equipment (UE), the gNB transmits a new transmission with an adjusted DCI and/or an adjusted grant to increase a probability that the expected uplink (UL) transmission is received from the UE. For example, a gNB may transmit a new DCI with a new Aggregation Level (AL) indicating a new UL grant to cause one or more of: an increase in UL power spectral density (PSD) on the PUSCH; a reduction in a number of allocated resource blocks (RB); a reduction in transport block size (TBS); a reduction in a Modulation and Coding Scheme (MCS) to use for the UE transmission; and use of different redundancy versions (RV) for retransmissions.

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.
