SYSTEMS, METHODS AND DEVICES FOR UPLINK TRANSMISSIONS WITH REDUCED SIGNALING OVERHEAD
First Claim
1. A computer program product comprising a computer-readable storage medium storing program code for causing one or more processors to perform a method, the method comprising:
- acquire a downlink (DL) synchronization signal of a wireless network;
determine resource pool information from system information data provided over the wireless network;
randomly select an uplink (UL) resource from within a resource pool;
transmit a scheduling request for the selected resource; and
when an acknowledgement (ACK) of the scheduling request is detected;
transmit data in the selected resource.

Abstract
Techniques, apparatus and methods are disclosed that enable reduced signaling overhead in a fifth generation (5G) wireless system. The system includes support for asynchronous uplink transmission, resource pool configuration, acknowledgement response and retransmission. For example, in a Type-1 transmission scheme, a user equipment (UE) selects one resource within the resource pool and transmits data in the uplink on the selected resource. In a Type-2 transmission scheme, a UE selects one resource within a scheduling request (SR) region in the resource pool, transmits the SR for the resource which contains the resource allocation for data transmission, and transmits the uplink data on the resource which is indicated in the SR information. In a Type-3 transmission scheme, a UE selects a resource within the SR region, transmits the SR on the selected resource with information on the resource selected for subsequent data transmission and transmits on the indicated resource if it receives an acknowledgment, in response to its transmitted SR.

11. A user equipment (UE) comprising:
-
a wireless interface configured to communicate over one or more radio access technologies (RATs) with an enhanced node B (eNB); and a processor to provide uplink transmission through the one or more RATs to the eNB, the a processor configured to; acquire a downlink (DL) synchronization signal from the eNB; obtain an uplink (UL) resource pool information from a System Information Block (SIB) transmitted by the eNB; transmit, through the wireless interface, data in a selected uplink resource from a resource pool to the eNB without approval of the eNB; and determine whether the data was received by the eNB. - View Dependent Claims (12, 13, 14, 15)

16. A baseband processor for a user equipment (UE) comprising:
baseband circuitry configured to; receive a synchronization signal provided over a mobile broadband network by a base station; determine a set of uplink resources within the mobile broadband network of the base station; randomly select a resource from within the set of uplink resources; transmit a scheduling request for the selected resource to the base station; and transmit data in a selected resource to the base station. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
