Early disclosure of destination address for fast information transfer in 5G
A wireless data message 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.
1. A method for a user node of a wireless network to transmit a wireless data message to a destination outside the wireless network, the method comprising:
transmitting one or more messages, the one or more messages comprising an indicator of a destination address of the data message, an uplink request, and a BSR (buffer status report) message;
then receiving, on a PDCCH (physical downlink control channel), an uplink grant for uploading the data message; and
then transmitting the data message on a PUSCH (physical uplink shared channel);
such that the transmitting of the indicator of the destination address before the data message enables a base station or a core network or both to plan a multi-hop transmission methodology for transmission of the data message to the destination address prior to or contemporaneous with the data message being uploaded by the user node to the base station, wherein the transmission of the data message occurs sooner than in a case where the multi-hop transmission is not planned prior to or contemporaneous with the data message being uploaded.
2. The method of claim 1 , wherein the address message is transmitted by the user node at a time and frequency assigned for scheduling request messages.
3. The method of claim 2 , wherein the address message comprises a request for an uplink grant.
4. The method of claim 1 , wherein the address message is transmitted in association with a BSR (buffer state report) message, the association being multiplexing or concatenation.
5. The method of claim 1 , wherein the address message is transmitted synchronously with a scheduling request message.
6. The method of claim 5 , wherein the address message is transmitted on a random access channel.
7. The method of claim 5 , wherein the address message is transmitted on a channel allocated for transmission of address messages.
8. The method of claim 5 , wherein synchronously comprises simultaneously.
9. The method of claim 5 , wherein synchronously comprises within a predetermined time interval.
