Flexible Aperiodic SRS Triggering in a Cellular Communication System - A simplified explanation of the abstract

This abstract first appeared for US patent application 18482702 titled 'Flexible Aperiodic SRS Triggering in a Cellular Communication System

Simplified Explanation

The abstract describes a patent application for a cellular base station and a user equipment (UE) that can transmit and receive flexible downlink control information (DCI). The DCI message can have different formats and may include specific instructions for the UE, such as transmitting an aperiodic SRS and not transmitting on the PUSCH. The base station can also generate a targeted DCI message for a group of UEs for greater efficiency.

• The patent application is for a cellular base station and UE that can transmit and process flexible downlink control information (DCI).
• The DCI message can have different formats, such as 0_1 or 0_2.
• The DCI message may include instructions for the UE, such as transmitting an aperiodic SRS and not transmitting on the PUSCH.
• The DCI message may also include existing fields for slot offset or beam information for transmitting the aperiodic SRS.
• The base station can generate a targeted DCI message for a group of UEs, improving efficiency.

Potential applications of this technology:

• Improved control and communication between base stations and UEs in cellular networks.
• Enhanced flexibility in transmitting control information to UEs.
• Efficient utilization of network resources by targeting specific groups of UEs.

Problems solved by this technology:

• Lack of flexibility in transmitting control information to UEs.
• Inefficient utilization of network resources.
• Difficulty in targeting specific groups of UEs for control information.

Benefits of this technology:

• Improved communication efficiency between base stations and UEs.
• Enhanced flexibility in controlling UEs' transmission behavior.
• Optimal utilization of network resources.
• Targeted transmission of control information for specific groups of UEs.

Original Abstract Submitted

A cellular base station (BS) which transmits more flexible downlink control information (DCI) to the UE, and a UE capable of receiving and processing a received DCI message. The DCI message may have a DCI format of 0_1 or 0_2 and further may comprise an UL-SCH set to 0, a CSI request field of all 0s and an SRS request field having a nonzero value. The DCI message may indicate to the UE that the UE should: 1) transmit an aperiodic SRS corresponding to SRS request; and 2) that the UE should not transmit on the PUSCH. The DCI may include existing fields that specify either a slot offset or beam information useable when transmitting the aperiodic SRS. The base station may also generate a DCI message with an SRS trigger that is targeted to a plurality of UEs in a group, or a plurality of groups of UEs, for greater efficiency.
