METHOD AND SYSTEMS FOR MULTIPLE PRECODER INDICATION FOR PHYSICAL UPLINK SHARED CHANNEL COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17441929 titled 'METHOD AND SYSTEMS FOR MULTIPLE PRECODER INDICATION FOR PHYSICAL UPLINK SHARED CHANNEL COMMUNICATIONS

Simplified Explanation

The patent application describes an approach for performing Physical Uplink Shared Channel (PUSCH) transmissions in wireless communication systems. Here are the key points:

• The approach involves a user equipment (UE) receiving an indicator from a base station. The indicator represents a set of precoders corresponding to multiple PUSCH repetitions.
• The UE configures the precoders based on the indicator and transmits one or more PUSCH repetitions using the configured precoders.
• The indicator can be provided through higher layer signaling, such as transmission rank indicator (TRI) and transmission precoder matrix indicator (TPMI).
• The indicator can also be provided in a scheduling downlink control indicator (DCI) communication or within sounding reference signal (SRS) resource indicators (SRIs) of the scheduling DCI.

Potential applications of this technology:

• This technology can be applied in wireless communication systems, particularly in the uplink transmission of data from user equipment to base stations.
• It can improve the efficiency and reliability of PUSCH transmissions by allowing the UE to configure and use multiple precoders for different repetitions.

Problems solved by this technology:

• Traditional approaches for PUSCH transmissions may not fully utilize the available resources and may not adapt well to changing channel conditions.
• This technology solves these problems by providing a mechanism for the UE to receive and configure multiple precoders based on an indicator, enabling more efficient and adaptive PUSCH transmissions.

Benefits of this technology:

• By using multiple precoders, the UE can optimize the transmission for different repetitions, leading to improved overall performance.
• The approach allows for better adaptation to varying channel conditions, resulting in increased reliability and throughput for PUSCH transmissions.
• The use of higher layer signaling and indicators simplifies the configuration process and enhances the flexibility of the system.

Original Abstract Submitted

Approaches for performing Physical Uplink Shared Channel (PUSCH) transmissions include receiving, by a user equipment (UE) from a base station, an indicator of a plurality of precoders corresponding to M Physical Uplink Shared Channel (PUSCH) repetitions, wherein M is an integer. A plurality of precoders corresponding to two or more of the M PUSCH repetitions are indicated. The UE configures the plurality of precoders based on the indicator and transmits one or more of the M Physical Uplink Shared Channel (PUSCH) repetitions corresponding to one or more of the plurality of precoders. The indicator can be provided in higher layer signaling. One or more transmission rank indicator (TRIs) and transmission precoder matrix indicators (TPMIs) for the M PUSCH repetitions can be provided. The indicator can be provided in a scheduling downlink control indicator (DCI) communication. The indicator can also be provided within N sounding reference signal (SRS) resource indicator(s) (SRIs) of the scheduling DCI.
