Abstract: Disclosed are systems and methods for reducing delays and obtaining rapid uplink access in 5G and 6G, by transmitting pre-grant messages on a random access channel. In one version, a user transmitting an SR (scheduling request) message at a pre-assigned time may transmit a second message on a random access channel synchronized with the SR message. For example, the second message may be a BSR (size) message, thereby avoiding additional delays. In another version, the user may transmit a series of messages on the random access channel without waiting for an uplink grant, thereby reducing delays further. The methods can generally be implemented by software upgrades, a cost-saving advantage. AI (artificial intelligence) may be used to determine which users may transmit messages pre-grant, and on which random access channels.

Abstract: A wireless data message in 5G/6G generally includes the destination address (such as MAC address) encoded in a field of the data message. A base station must receive the data message and decode the address before the core network can deliver the message to the recipient's cell. For faster communication, certain address messages are disclosed, by which the destination address may be disclosed before the data message is uploaded. Early disclosure of the destination address may enable the core network to deliver the data message to the recipient with fewer delays. In various configurations, the destination address may be provided concurrently with a scheduling request, or combined with a BSR (size) message, or delivered on a random access channel, among other possibilities. For faster uploads, a pointer or code representing the destination address can be specified, resulting in further delay reductions.
