USER EQUIPMENT DIRECT TRANSMISSION WHILE INACTIVE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17441326 titled 'USER EQUIPMENT DIRECT TRANSMISSION WHILE INACTIVE

Simplified Explanation

The patent application describes a method for allowing an inactive user equipment (UE) to transmit uplink data to a base station using a contention-free random access process. Here is a simplified explanation of the abstract:

• The method involves receiving configuration information from the network regarding a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource.
• While in an inactive state, without entering a connected state, the UE uses a contention-free random access process to transmit uplink data to the base station using the dedicated PRACH/preamble resource.

Potential applications of this technology:

• This technology can be used in cellular networks to improve the efficiency of uplink data transmission from inactive UEs.
• It can be particularly useful in scenarios where UEs need to transmit small amounts of data sporadically, without the need to establish a full connection with the network.

Problems solved by this technology:

• Inactive UEs typically cannot transmit uplink data without first establishing a connection with the network, which can be time-consuming and resource-intensive.
• This technology solves this problem by allowing inactive UEs to directly transmit uplink data using a contention-free random access process, without the need for a full connection.

Benefits of this technology:

• Improved efficiency: By allowing inactive UEs to transmit uplink data directly, the technology reduces the time and resources required for establishing a connection.
• Enhanced network capacity: The use of contention-free random access process enables more efficient utilization of network resources, leading to increased network capacity.
• Reduced latency: Inactive UEs can quickly transmit small amounts of data without the need for connection establishment, resulting in reduced latency for certain applications.

Original Abstract Submitted

Systems, methods, and circuitries are provided for direct transmission of uplink data by an INACTIVE UE using a contention free random access (CFRA) process. In one example, a method, includes, receiving, from a network, configuration of a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource (dedicated PRACH/preamble resource); and while in a radio resource control (RRC) INACTIVE state, without entering an RRC CONNECTED state, using a contention-free random access (CFRA) process to transmit uplink data to a base station using the dedicated PRACH/preamble resource.
