A system and method for performing a Random Access Channel (RACH) procedure is provided. The method includes configuring a plurality of Bandwidths Parts (BWPs) to one or more Physical Random Access Channel (PRACH) occasions mapped to a public land mobile network identification (PLMN-ID) of a set of different PLMN-IDs, each different PLMN-ID is assigned with at least one operator of a set of operators; assigning each PRACH occasion within an uplink (UL) transmission wherein each PRACH occasion is allocated by the host operator to at least one operator; separating each PRACH occasion of a set of PRACH occasions based on each PLMN-ID of the set of PLMN-IDs; and enabling a User Equipment (UE) operating at a cell site of the RACH procedure via at least one PRACH occasion allocated by the host operator based on the PLMN-ID that has been mapped to subscribers for at least one operator.

Fallback aspects associated with the power ramping procedure are addressed. More specifically, a set of control mechanisms allows for a gNB to adjust thresholds for controlling the UE transfer from a 2-step RACH procedure to a 4-step RACH procedure while still maintaining a proper setting for transmit power during this transition. The mechanism will allow for a UE to have a smooth transition to the 4-step procedure instead of having to start the power ramping from scratch when transferring to the fall-back routine.

Wireless communications are described for access procedures. A wireless device may use a plurality of identifiers to monitor for a response from a base station. The wireless device may determine whether a random access procedure is a success or a failure based on the identifier that the wireless device is able to use to receive the response.

The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). Accordingly, embodiments herein disclose a system and method for handling resource allocation in wireless communication system. The method includes registering, by a UE, a first SIM among a plurality of SIMs with a first network entity in the wireless communication system and a second SIM among plurality of SIMs with a second network entity in wireless communication system. Further, the method includes configuring, by the UE, a RF resource with the first SIM for at least one of a downlink reception and uplink transmission. Further, the method includes determining, by the UE, whether second SIM needs RF resource. Further, the method includes performing, by the UE, provisioning of RF resource based on the determination.

Granting access to a communication channel for a user device by a base station includes receiving, from a user device, a request to access the communication channel, the request including a random access preamble and a payload, attempting to decode the payload, selecting a format of a response message in accordance with whether the payload was decoded successfully, and transmitting, to the user device, the response message, including providing an indication of the format of the response message to the user device.

Systems and methods for enhanced random access procedure are provided. A wireless communication device can receive, from a wireless communication node, information indicating a value. The wireless communication device can compare a randomly generated value with the value. The wireless communication device can select, based on the comparison, either a 4-step random access procedure or a 2-step random access procedure to access to the wireless communication node. The wireless communication device can transmit a first message to access to the wireless communication node, wherein content of the first message is based on the selection of the 4-step random access procedure or the 2-step random access procedure.

A user device (UE) for scheduling an uplink transmission assignment with a base station that communicates with the user device via a shared carrier, receives, from the base station, a configuration that indicates (i) a first channel access procedure for the user device to perform prior to transmitting an uplink transmission and (ii) at least one occasion at which the user device is to transmit the uplink transmission (1602); receives, from the base station via the shared carrier, a signal indicating at least a portion of a transmission time period during which the shared carrier is available to the base station (1604); and performs the first channel access procedure or a second channel access procedure before transmitting the uplink transmission based at least in part on whether the occasion is within the transmission time period (1606).
