Samsung patents 5G method to speed up connection setup with early signal checks

Samsung has been granted a patent for a communication method in 5G or 6G networks that allows a phone to send a specific test signal, called a sounding reference signal, immediately after initiating a connection. This early signal helps the network understand the quality of the connection before sending main data, allowing for better signal processing.

Why it mattersThis technical improvement could help mobile devices establish a stable connection faster by letting the network adjust its signal strength and direction sooner.

In the filing’s own words

The disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A communication method performed by a user equipment (UE) during a network communication procedure is provided. The communication method includes transmitting a random access preamble, receiving a modified random access response (RAR) comprising a sounding reference signal (SRS) request field whose value indicates whether the UE should transmit the SRS, when the SRS request field value indicates that the UE should transmit the SRS, transmitting the SRS, and receiving one or multiple subsequent downlink (DL) transmissions with adaptive spatial signal processing performed on the basis of a channel state information (CSI) acquired on the basis of measurements of the SRS.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a communication system, the method comprising: transmitting a random access preamble on a physical random access channel (PRACH); receiving, on a physical downlink shared channel (PDSCH), a random access response (RAR) associated with the random access preamble, wherein the RAR includes a transmit power control (TPC) field, a sounding reference signal (SRS) request field and an SRS TPC field, wherein a value of the TPC field indicates a transmit power for a radio resource control (RRC) connection setup request, a value of the SRS request field indicates whether to transmit the SRS and a value of the SRS TPC field indicates a transmit power for the SRS, and wherein the value of the SRS TPC field is different from the value of the TPC field; in case that the value of the SRS request field is one bit and indicates to transmit the SRS, transmitting the SRS using the transmit power indicated by the SRS TPC field; in case that the value of the SRS request field is two bits or three bits and indicates a predetermined configuration of the SRS among a plurality of predetermined configurations, transmitting the SRS based on the predetermined configuration indicated by the SRS request field using the transmit power indicated by the SRS TPC field; and receiving one or multiple subsequent downlink transmissions with adaptive spatial signal processing based on channel state information (CSI) associated with measurements of the SRS.
