Samsung patents 5G signal method to reduce interference between cell towers

This patent describes a way for 5G or 6G base stations to manage how phones send test signals back to the network. It uses specific patterns called cyclic shifts and comb offsets to separate signals from different antennas, helping the network handle multiple towers without them interfering with each other.

Why it mattersThis improves the efficiency of future mobile networks by reducing signal clutter when multiple cell towers serve the same area.

In the filing’s own words

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method is provided for handling SRS resource allocation in multi-TRP in wireless networks by a BS or a TRP unit. The method includes configuring CS allocation to at least one port of a UE. The CS allocation uses values from a sub-set of a plurality of allowable CS values. Further, the method includes receiving a SRS using the allocated CS. In an embodiment, per-port CS allocation provides flexibility of using the CS resources efficiently to minimize inter-TRP interference. The method can be used to allocate CS and SRS resources efficiently.

What exactly they claim (claim 1)

1. A method performed by a base station (BS) in a wireless communication system, the method comprising: transmitting, to a user equipment (UE), a radio resource control (RRC) message including configuration information on a sounding reference signal (SRS) resource, wherein the configuration information includes information on a comb offset hopping and information on a cyclic shift hopping; and receiving, from the UE, an SRS based on the configuration information on the SRS resource, wherein the comb offset hopping and the acyclic shift hopping are applied to the SRS based on the configuration information, wherein cyclic shifts of antenna ports for orthogonal frequency-division multiplexing (OFDM) symbols include at least one first subset, and wherein the cyclic shift hopping is based on a first hopping identity (ID) and the comb hopping is based on a second hopping ID.
