METHOD FOR TRANSMITTING SOUNDING REFERENCE SIGNAL FOR USER EQUIPMENT WITH ASYMMETRIC TRANSMIT/RECEIVE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18455955 titled 'METHOD FOR TRANSMITTING SOUNDING REFERENCE SIGNAL FOR USER EQUIPMENT WITH ASYMMETRIC TRANSMIT/RECEIVE

Simplified Explanation

- User equipment (UE) can transmit a message indicating its supported transmit antenna switching (TxAS) capability for each port. - The UE receives a configuration message indicating an uplink multiple-input/multiple-output (UL MIMO) configuration based on the UE's TxAS capability. - The UE identifies a sounding reference signal (SRS) configuration for transmitting SRSs in conjunction with UL MIMO communications. - The SRS configuration includes a configuration for transmitting SRSs using one or more ports of the UE, selected based on a TxAS configuration for each port.

Potential Applications

- Wireless communication systems - 5G networks - Mobile devices

Problems Solved

- Efficient use of multiple antennas in wireless communications - Optimizing UL MIMO configurations based on UE capabilities

Benefits

- Improved signal transmission quality - Enhanced network capacity - Better overall performance in wireless communication systems

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message, the UE capability message indicating a supported transmit antenna switching (TxAS) capability for each port of the UE. The UE may receive a configuration message indicating an uplink multiple-input/multiple-output (UL MIMO) configuration for the UE, the UL MIMO configuration being based at least in part on the UE capability message. The UE may identify, based at least in part on the configuration message, a sounding reference signal (SRS) configuration to use for transmitting SRSs in conjunction with the UL MIMO communications, the SRS configuration comprising a configuration for transmission by the UE of SRSs using at least one of the two or more ports of the UE, the SRSs transmitted on one or more antennas of the UE selected according to a TxAS configuration for the respective port.
